But, the new town is often of high-intensity development, bringing a series of natural, ecological and environmental issues, so it is difficult to achieve sustainable development. In this paper, taking the administrative center of Jiangping in Dongxing as an example. It is analyzed from the following three aspects：Vertical design of road traffic，Space layout of mountain buildings，and the design of landscape. The purpose is to elaborate the hillside design methods guided by low-intensity damage, and explore the guiding significance of sustainable development of the hillside construction in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-intensity%20damage" title="low-intensity damage">low-intensity damage</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20town%20construction%EF%BC%8Chillside%EF%BC%8Csustainable%20development" title=" new town construction，hillside，sustainable development"> new town construction，hillside，sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=natural" title=" natural"> natural</a>, <a href="https://publications.waset.org/abstracts/search?q=ecology" title=" ecology"> ecology</a> </p> <a href="https://publications.waset.org/abstracts/30503/the-analysis-of-new-town-hillside-development-pattern-guided-by-low-intensity-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> An Algorithm for Removal of Noise from X-Ray Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajidullah%20Khan">Sajidullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Najeeb%20Ullah"> Najeeb Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Yin%20Chai"> Wang Yin Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chai%20Soo%20See"> Chai Soo See</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose an approach to remove impulse and Poisson noise from X-ray images. Many filters have been used for impulse noise removal from color and gray scale images with their own strengths and weaknesses but X-ray images contain Poisson noise and unfortunately there is no intelligent filter which can detect impulse and Poisson noise from X-ray images. Our proposed filter uses the upgraded layer discrimination approach to detect both Impulse and Poisson noise corrupted pixels in X-ray images and then restores only those detected pixels with a simple efficient and reliable one line equation. Our Proposed algorithms are very effective and much more efficient than all existing filters used only for Impulse noise removal. The proposed method uses a new powerful and efficient noise detection method to determine whether the pixel under observation is corrupted or noise free. Results from computer simulations are used to demonstrate pleasing performance of our proposed method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-ray%20image%20de-noising" title="X-ray image de-noising">X-ray image de-noising</a>, <a href="https://publications.waset.org/abstracts/search?q=impulse%20noise" title=" impulse noise"> impulse noise</a>, <a href="https://publications.waset.org/abstracts/search?q=poisson%20noise" title=" poisson noise"> poisson noise</a>, <a href="https://publications.waset.org/abstracts/search?q=PRWF" title=" PRWF"> PRWF</a> </p> <a href="https://publications.waset.org/abstracts/54256/an-algorithm-for-removal-of-noise-from-x-ray-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54256.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> A Study on Finite Element Modelling of Earth Retaining Wall Anchored by Deadman Anchor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20S.%20Chai">K.

Community home-based care for the aged is an important solution to old-age care in aging society. In this aspect, Europe, the United States and Japan are on the top in the world. As an East Asian country, Japan has similar cultural traditions in pension with China. So, there is much enlightenment China can get from Japan in the mode of community home-based care for the aged. This paper introduces the mode of community home-based care for the aged in Kishiwada, Japan and Hangzhou, China. Then compare the two modes in the aspects of insurance system for the aged, community service and facilities, support system and so on. Thereby the success experience of Kishiwada and weaknesses of Hangzhou are summarized. At last, the improvement strategy of facility plan and service mode of community home-based care for the aged in China are also proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison" title=" comparison"> comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly-oriented" title=" elderly-oriented"> elderly-oriented</a>, <a href="https://publications.waset.org/abstracts/search?q=home-based%20care%20for%20the%20aged" title=" home-based care for the aged"> home-based care for the aged</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20system" title=" support system"> support system</a> </p> <a href="https://publications.waset.org/abstracts/63994/the-comparison-of-community-home-based-care-for-the-aged-in-kishiwada-japan-and-hangzhou-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63994.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> The Existence of Field Corn Networks on the Thailand-Burma Border under the Patron-Client Contract Farming System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kettawa%20Boonprakarn">Kettawa Boonprakarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jedsarid%20Sangkaphan"> Jedsarid Sangkaphan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bejapornd%20Deekhuntod"> Bejapornd Deekhuntod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuntharat%20Suriyo"> Nuntharat Suriyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to investigate the existence of field corn networks on the Thailand-Burma border under the patron-client contract farming system. The data of this qualitative study were collected through in-depth interviews with nine key informants. The results of the study revealed that the existence of the field corn networks was associated with the relationship where farmers had to share their crops with protectors in the areas under the influence of the KNU (Karen National Union) and the DKBA (Democratic Karen Buddhist Army) or Burmese soldiers. A Mae Liang, the person who starts a network has a connection with a Thaokae, Luk Rai Hua Chai or the head of a group of farmers, and farmers. They are under the patron-client system with trust and loyalty that enable the head of the group and the farmers in the Burma border side to remain under the same Mae Liang even though the business has been passed down to later generations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existence" title="existence">existence</a>, <a href="https://publications.waset.org/abstracts/search?q=field-corn%20networks" title=" field-corn networks"> field-corn networks</a>, <a href="https://publications.waset.org/abstracts/search?q=patron-client%20system" title=" patron-client system"> patron-client system</a>, <a href="https://publications.waset.org/abstracts/search?q=contract%20farming" title=" contract farming"> contract farming</a> </p> <a href="https://publications.waset.org/abstracts/3431/the-existence-of-field-corn-networks-on-the-thailand-burma-border-under-the-patron-client-contract-farming-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3431.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Intended-Actual First Asking/Offer Price Discrepancies and Their Impact on Negotiation Behaviour and Outcomes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liuyao%20Chai">Liuyao Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Colin%20Clark"> Colin Clark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of 574 participants in a simulated two-person distributive negotiation revealed that the first price 245 (42.7%) of these participants actually asked/offered for the item under negotiation (a used car) differed from the first price they previously stated they intended to ask/offer during their negotiation. This discrepancy between a negotiator’s intended first asking/offer price and his/her actual first asking/offer price had a significant and economically consequential impact on both the course and the outcomes of the negotiations studied. Participants whose actual first price remained the same as their intended first price tended to secure better negotiation outcomes. Moreover, participants who changed their intended first price tended to obtain relatively lower outcomes regardless of whether their modified first announced price had created a negotiating position that was ‘stronger’ or ‘weaker’ than if they had opened with their intended first price. Subsequent investigation of over twenty negotiation behaviours and pre-negotiation perceptual variables within this dataset indicated that the three types of first price announcers—i.e. intended first asking/offer price ‘weakeners’, ‘maintainers’ and ‘strengtheners’— comprised persons who tended to have significantly different pre-negotiation perceptions and behaved in systematically different ways during their negotiation. Typically, the most negative, outcome-compromising consequences of changing, weakening or strengthening an intended first price occurred at the very beginning of a negotiation when participants exchanged their actual first asking/offer prices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20communication" title="business communication">business communication</a>, <a href="https://publications.waset.org/abstracts/search?q=negotiation" title=" negotiation"> negotiation</a>, <a href="https://publications.waset.org/abstracts/search?q=persuasion" title=" persuasion"> persuasion</a>, <a href="https://publications.waset.org/abstracts/search?q=intended%20first%20asking%2Foffer%20prices" title=" intended first asking/offer prices"> intended first asking/offer prices</a>, <a href="https://publications.waset.org/abstracts/search?q=bargaining" title=" bargaining"> bargaining</a> </p> <a href="https://publications.waset.org/abstracts/24182/intended-actual-first-askingoffer-price-discrepancies-and-their-impact-on-negotiation-behaviour-and-outcomes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Racial Microaggressions: Experiences among International Students in Australia and Its Impact on Stress and Psychological Wellbeing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20M.%20Gonzales">Hugo M.

This study investigated the prevalence of racial microaggressions among international students and their impact on stress and psychological well-being. This research was conducted during the COVID-19 pandemic, which has been documented to contribute to anti-Asian racism. Participants included 54 international students, of which 72% were Asian. The Racial and Ethnic Microaggressions Scale (REMS), Perceived Stress Scale (PSS), and the Perceived General Wellbeing Indicator (PGWBI) were used to measure the participants’ responses. All participants reported experiencing racial microaggression in the last six months, and significant correlations and regression models were found between REMS, certain elements of the PSS scale, and time in Australia. Despite the small sample size, this research corroborated outcomes from recent studies and provided insight into the prevalence and impact of racial microaggressions among such populations, highlighting the need for further exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=racial%20microaggressions" title="racial microaggressions">racial microaggressions</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20students" title=" international students"> international students</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=REMS" title=" REMS"> REMS</a>, <a href="https://publications.waset.org/abstracts/search?q=microaggressions%20in%20Australia" title=" microaggressions in Australia"> microaggressions in Australia</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20wellbeing" title=" psychological wellbeing"> psychological wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/160533/racial-microaggressions-experiences-among-international-students-in-australia-and-its-impact-on-stress-and-psychological-wellbeing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Experimental Investigations on the Mechanism of Stratified Liquid Mixing in a Cylinder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chai%20Mingming">Chai Mingming</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Lei"> Li Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Xiaoxia"> Lu Xiaoxia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the mechanism of stratified liquids’ mixing in a cylinder is investigated. It is focused on the effects of Rayleigh-Taylor Instability (RTI) and rotation of the cylinder on liquid interface mixing. For miscible liquids, Planar Laser Induced Fluorescence (PLIF) technique is applied to record the concentration field for one liquid. Intensity of Segregation (IOS) is used to describe the mixing status. For immiscible liquids, High Speed Camera is adopted to record the development of the interface. The experiment of RTI indicates that it plays a great role in the mixing process, and meanwhile the large-scale mixing is triggered, and subsequently the span of the stripes decreases, showing that the mesoscale mixing is coming into being. The rotation experiments show that the spin-down process has a great role in liquid mixing, during which the upper liquid falls down rapidly along the wall and crashes into the lower liquid. During this process, a lot of interface instabilities are excited. Liquids mix rapidly in the spin-down process. It can be concluded that no matter what ways have been adopted to speed up liquid mixing, the fundamental reason is the interface instabilities which increase the area of the interface between liquids and increase the relative velocity of the two liquids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interface%20instability" title="interface instability">interface instability</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20mixing" title=" liquid mixing"> liquid mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayleigh-Taylor%20Instability" title=" Rayleigh-Taylor Instability"> Rayleigh-Taylor Instability</a>, <a href="https://publications.waset.org/abstracts/search?q=spin-down%20process" title=" spin-down process"> spin-down process</a>, <a href="https://publications.waset.org/abstracts/search?q=spin-up%20process" title=" spin-up process"> spin-up process</a> </p> <a href="https://publications.waset.org/abstracts/51374/experimental-investigations-on-the-mechanism-of-stratified-liquid-mixing-in-a-cylinder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Incorporating Priority Round-Robin Scheduler to Sustain Indefinite Blocking Issue and Prioritized Processes in Operating System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heng%20Chia%20Ying">Heng Chia Ying</a>, <a href="https://publications.waset.org/abstracts/search?q=Charmaine%20Tan%20Chai%20Nie"> Charmaine Tan Chai Nie</a>, <a href="https://publications.waset.org/abstracts/search?q=Burra%20Venkata%20Durga%20Kumar"> Burra Venkata Durga Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Process scheduling is the method of process management that determines which process the CPU will proceed with for the next task and how long it takes.

Deuterated potassium dihydrogen phosphate (DKDP) crystal is an optimal choice for converting the Nd: glass radiation to the fourth harmonic laser by noncritical phase matching (NCPM). To reduce the damage probability of focusing lens, the DKDP crystal is suggested to be set before the focusing lens. And a converging beam enters the FHG crystal consequently. In this paper, we simulate the process of FHG in the scheme and the dependence of FHG efficiency on the lens’ F is derived. Besides, DKDP crystal with gradient deuterium is proposed to realize the NCPM FHG of the converging beam. At every position, the phase matching is achieved by adjusting the deuterium level, and the FHG efficiency increases as a result. The relation of the lens’ F with the deuterium gradient is investigated as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fourth%20harmonic%20generation" title="fourth harmonic generation">fourth harmonic generation</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20induced%20damage" title=" laser induced damage"> laser induced damage</a>, <a href="https://publications.waset.org/abstracts/search?q=converging%20beam" title=" converging beam"> converging beam</a>, <a href="https://publications.waset.org/abstracts/search?q=DKDP%20crystal" title=" DKDP crystal"> DKDP crystal</a> </p> <a href="https://publications.waset.org/abstracts/103692/noncritical-phase-matched-fourth-harmonic-generation-of-converging-beam-by-deuterated-potassium-dihydrogen-phosphate-crystal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> The Development of Leisure and Endowment Characteristic Villages in the Perspective of Balancing the Dwellers and Aged Visitors：A Case Study of Villages in Hangzhou Metropolitan Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zijiao%20Chai">Zijiao Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Wangming%20Li"> Wangming Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Under the background of increasing aging population, the situation of city endowment resources shortage gradually revealed.

This paper is based on a survey of more than ten villages which are characterized by leisure and endowment in Hangzhou metropolitan area, China. The satisfaction degree of the two main groups in the villages, dwellers, and aged visitors, is researched using the method of fuzzy comprehensive evaluation. The statistics are obtained from 535 questionnaires and qualitative interview. According to the satisfaction scores, it could be determined whether the dwellers and aged visitors have reached the equilibrium state. The equilibrium state is the development target of the villages, and it`s defined by environmentally friendly, proper for employment and pension, facilities sharing and harmonious life for each other.

In this study, the phospholipids was extracted from squid skin and manufactured into a liposome (SQ liposome) to mimic apoptotic body. We then evaluated anti-inflammatory effects of SQ liposome on mouse microglial cell line (BV-2) by lipopolysaccharide (LPS) induction. First, the major phospholipid constituents in the squid skin extract were including 46.2% of phosphatidylcholine, 18.4% of phosphatidylethanolamine, 7.7% of phosphatidylserine, 3.5% of phosphatidylinositol, 4.9% of Lysophosphatidylcholine and 19.3% of other phospholipids by HPLC-UV analysis. The contents of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the squid skin extract were 11.8 and 28.7%, respectively. The microscopic images showed that microglia cells can engulf apoptotic cells or SQ-liposome. In cell based studies, there was no cytotoxicity to BV-2 as the concentration of SQ-liposome was less than 2.5 mg/mL. The LPS induced pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), were significant suppressed (P < 0.05) by pretreated 0.03~2.5mg/ml SQ liposome. Oppositely, the anti-inflammatory cytokines transforming growth factor-beta (TGF-β) and interleukin-10 (IL-10) secretion were enhanced (P < 0.05). The results suggested that SQ-liposome possess anti-inflammatory properties on BV-2 and may be a good strategy for against neuro-inflammatory disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apoptotic%20mimicry" title="apoptotic mimicry">apoptotic mimicry</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroinflammation" title=" neuroinflammation"> neuroinflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=microglia" title=" microglia"> microglia</a>, <a href="https://publications.waset.org/abstracts/search?q=squid%20processing%20by-products" title=" squid processing by-products"> squid processing by-products</a> </p> <a href="https://publications.waset.org/abstracts/78159/inflammatory-alleviation-on-microglia-cells-by-an-apoptotic-mimicry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78159.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">483</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Experimental Study on the Effect of Storage Conditions on Thermal Hazard of Nitrocellulose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hua%20Chai">Hua Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiangling%20Duan"> Qiangling Duan</a>, <a href="https://publications.waset.org/abstracts/search?q=Huiqi%20Cao"> Huiqi Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi%20Li"> Mi Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinhua%20Sun"> Jinhua Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nitrocellulose (NC), a kind of energetic material, has been widely used in the industrial and military fields. However, this material can also cause serious social disasters due to storage conditions. Thermal hazard of nitrocellulose (NC) was experimentally investigated using the CALVET heat flux calorimeter C80, and three kinds of storage conditions were considered in the experiments: (1) drying time, (2) moisture content, (3) cycles. The results showed that the heat flow curves of NC moved to the low-temperature direction firstly and then slightly moved back by increasing the drying hours. Moisture that was responsible for the appearance of small exothermic peaks was proven to be the unfavorable safety factor yet it could increase the onset temperature of the main peak to some extent. And cycles could both lower the onset temperature and the maximum heat flow but enlarged the peak temperature. Besides, relevant kinetic parameters such as the heat of reaction (ΔH) and the activation energy (Ea) were obtained and compared. It was found that all the three conditions could reduce the values of Ea and most of them produced larger reaction heat. In addition, the critical explosion temperature (Tb) of the NC samples were derived. It was clear that not only the drying time but also the cycles would increase the thermal hazard of the NC. Yet, the right amount of water helped to reduce the thermal hazard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C80" title="C80">C80</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrocellulose" title=" nitrocellulose"> nitrocellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20conditions" title=" storage conditions"> storage conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20critical%20explosion%20temperature" title=" the critical explosion temperature"> the critical explosion temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20hazard" title=" thermal hazard"> thermal hazard</a> </p> <a href="https://publications.waset.org/abstracts/107946/experimental-study-on-the-effect-of-storage-conditions-on-thermal-hazard-of-nitrocellulose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Developing Pavement Structural Deterioration Curves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gregory%20Kelly">Gregory Kelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Gary%20Chai"> Gary Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittampalam%20Manoharan"> Sittampalam Manoharan</a>, <a href="https://publications.waset.org/abstracts/search?q=Deborah%20Delaney"> Deborah Delaney</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Structural Number (SN) can be calculated for a road pavement from the properties and thicknesses of the surface, base course, sub-base, and subgrade. Historically, the cost of collecting structural data has been very high. Data were initially collected using Benkelman Beams and now by Falling Weight Deflectometer (FWD). The structural strength of pavements weakens over time due to environmental and traffic loading factors, but due to a lack of data, no structural deterioration curve for pavements has been implemented in a Pavement Management System (PMS). International Roughness Index (IRI) is a measure of the road longitudinal profile and has been used as a proxy for a pavement’s structural integrity. This paper offers two conceptual methods to develop Pavement Structural Deterioration Curves (PSDC). Firstly, structural data are grouped in sets by design Equivalent Standard Axles (ESA). An ‘Initial’ SN (ISN), Intermediate SN’s (SNI) and a Terminal SN (TSN), are used to develop the curves. Using FWD data, the ISN is the SN after the pavement is rehabilitated (Financial Accounting ‘Modern Equivalent’). Intermediate SNIs, are SNs other than the ISN and TSN. The TSN was defined as the SN of the pavement when it was approved for pavement rehabilitation. The second method is to use Traffic Speed Deflectometer data (TSD). The road network already divided into road blocks, is grouped by traffic loading. For each traffic loading group, road blocks that have had a recent pavement rehabilitation, are used to calculate the ISN and those planned for pavement rehabilitation to calculate the TSN. The remaining SNs are used to complete the age-based or if available, historical traffic loading-based SNI’s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual" title="conceptual">conceptual</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20structural%20number" title=" pavement structural number"> pavement structural number</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20structural%20deterioration%20curve" title=" pavement structural deterioration curve"> pavement structural deterioration curve</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20management%20system" title=" pavement management system"> pavement management system</a> </p> <a href="https://publications.waset.org/abstracts/83307/developing-pavement-structural-deterioration-curves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">544</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Foot-and-Mouth Virus Detection in Asymptomatic Dairy Cows without Foot-and-Mouth Disease Outbreak</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duanghathai%20Saipinta">Duanghathai Saipinta</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanittian%20Panyamongkol"> Tanittian Panyamongkol</a>, <a href="https://publications.waset.org/abstracts/search?q=Witaya%20Suriyasathaporn"> Witaya Suriyasathaporn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Animal management aims to provide a suitable environment for animals allowing maximal productivity in those animals. Prevention of disease is an important part of animal management. Foot-and-mouth disease (FMD) is a highly contagious viral disease in cattle and is an economically important animal disease worldwide. Monitoring the FMD virus in farms is useful management for the prevention of the FMD outbreak. A recent publication indicated collection samples from nasal swabs can be used for monitoring FMD in symptomatic cows. Therefore, the objectives of this study were to determine the FMD virus in asymptomatic dairy cattle using nasal swab samples during the absence of an FMD outbreak. The study was conducted from December 2020 to June 2021 using 185 asymptomatic signs of FMD dairy cattle in Chiang Mai Province, Thailand. By random cow selection, nasal mucosal swabs were used to collect samples from the selected cows and then were to evaluate the presence of FMD viruses using the real-time rt-PCR assay. In total, 4.9% of dairy cattle detected FMD virus, including 2 dairy farms in Mae-on (8 samples; 9.6%) and 1 farm in the Chai-Prakan district (1 sample; 1.2%). Interestingly, both farms in Mae-on were the outbreak of the FMD after this detection for 6 months. This indicated that the FMD virus presented in asymptomatic cattle might relate to the subsequent outbreak of FMD. The outbreak demonstrates the presence of the virus in the environment. In conclusion, monitoring of FMD can be performed by nasal swab collection. Further investigation is needed to show whether the FMD virus presented in asymptomatic FMD cattle could be the cause of the subsequent FMD outbreak or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cattle" title="cattle">cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=foot-and-mouth%20disease" title=" foot-and-mouth disease"> foot-and-mouth disease</a>, <a href="https://publications.waset.org/abstracts/search?q=nasal%20swab" title=" nasal swab"> nasal swab</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20rt-PCR%20assay" title=" real-time rt-PCR assay"> real-time rt-PCR assay</a> </p> <a href="https://publications.waset.org/abstracts/160071/foot-and-mouth-virus-detection-in-asymptomatic-dairy-cows-without-foot-and-mouth-disease-outbreak" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Research on Container Housing: A New Form of Informal Housing on Urban Temporary Land</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lufei%20Mao">Lufei Mao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongwei%20Chen"> Hongwei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zijiao%20Chai"> Zijiao Chai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Informal housing is a widespread phenomenon in developing countries. In many newly-emerging cities in China, rapid urbanization leads to an influx of population as well as a shortage of housing. Under this background, container housing, a new form of informal housing, gradually appears on a small scale on urban temporary land in recent years. Container housing, just as its name implies, transforms containers into small houses that allow migrant workers group to live in it. Scholars in other countries have established sound theoretical frameworks for informal housing study, but the research fruits seem rather limited on this small scale housing form. Unlike the cases in developed countries, these houses, which are outside urban planning, bring about various environmental, economic, social and governance issues. Aiming to figure out this new-born housing form, a survey mainly on two container housing settlements in Hangzhou, China was carried out to gather the information of them. Based on this thorough survey, the paper concludes the features and problems of infrastructure, environment and social communication of container housing settlements. The result shows that these containers were lacking of basic facilities and were restricted in a small mess temporary land. Moreover, because of the deficiency in management, the rental rights of these containers might not be guaranteed. Then the paper analyzes the factors affecting the formation and evolution of container housing settlements. It turns out that institutional and policy factors, market factors and social factors were the main three factors that affect the formation. At last, the paper proposes some suggestions for the governance of container housing and the utility pattern of urban temporary land. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=container%20housing" title="container housing">container housing</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20housing" title=" informal housing"> informal housing</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20temporary%20land" title=" urban temporary land"> urban temporary land</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20governance" title=" urban governance"> urban governance</a> </p> <a href="https://publications.waset.org/abstracts/71245/research-on-container-housing-a-new-form-of-informal-housing-on-urban-temporary-land" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> The Effect of Foundation on the Earth Fill Dam Settlement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Ghaemi">Masoud Ghaemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadjafar%20Hedayati"> Mohammadjafar Hedayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Faezeh%20Yousefzadeh"> Faezeh Yousefzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoseinali%20Heydarzadeh"> Hoseinali Heydarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Careful monitoring in the earth dams to measure deformation caused by settlement and movement has always been a concern for engineers in the field. In order to measure settlement and deformation of earth dams, usually, the precision instruments of settlement set and combined Inclinometer that is commonly referred to IS instrument will be used. In some dams, because the thickness of alluvium is high and there is no possibility of alluvium removal (technically and economically and in terms of performance), there is no possibility of placing the end of IS instrument (precision instruments of Inclinometer-settlement set) in the rock foundation. Inevitably, have to accept installing pipes in the weak and deformable alluvial foundation that leads to errors in the calculation of the actual settlement (absolute settlement) in different parts of the dam body. The purpose of this paper is to present new and refine criteria for predicting settlement and deformation in earth dams. The study is based on conditions in three dams with a deformation quite alluvial (Agh Chai, Narmashir and Gilan-e Gharb) to provide settlement criteria affected by the alluvial foundation. To achieve this goal, the settlement of dams was simulated by using the finite difference method with FLAC3D software, and then the modeling results were compared with the reading IS instrument. In the end, the caliber of the model and validate the results, by using regression analysis techniques and scrutinized modeling parameters with real situations and then by using MATLAB software and CURVE FITTING toolbox, new criteria for the settlement based on elasticity modulus, cohesion, friction angle, the density of earth dam and the alluvial foundation was obtained. The results of these studies show that, by using the new criteria measures, the amount of settlement and deformation for the dams with alluvial foundation can be corrected after instrument readings, and the error rate in reading IS instrument can be greatly reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth-fill%20dam" title="earth-fill dam">earth-fill dam</a>, <a href="https://publications.waset.org/abstracts/search?q=foundation" title=" foundation"> foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference" title=" finite difference"> finite difference</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a>, <a href="https://publications.waset.org/abstracts/search?q=curve%20fitting" title=" curve fitting"> curve fitting</a> </p> <a href="https://publications.waset.org/abstracts/135983/the-effect-of-foundation-on-the-earth-fill-dam-settlement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135983.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Effects of Modified Low-Dye Taping on First Ray Mobility Test and Sprint Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Ju%20Tsai">Yu-Ju Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Chun%20Wang"> Ching-Chun Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Tzu%20Tang"> Wen-Tzu Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huei-Ming%20Chai"> Huei-Ming Chai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A pronated foot is frequently associated with a hypermobile first ray, then developing further severe foot problems. Low-Dye taping with athletic tape has been widely used to restrict excessive first ray motion and re-build height of the medial longitudinal arch in general population with pronated foot. It is not the case, however, for sprinters since they feel too much restriction of foot motions. Currently, the kinesio tape, more elastic than the athletic tape, has been widely used to re-adjust joint positions. It was interesting whether modified low-Dye taping using kinesio tape was beneficial for altering first ray mobility and still giving enough arch support. The purpose of this study was to investigate the effect of modified low-Dye taping on first ray mobility test and 60-m sprint time for sprinters with pronated foot. The significance of this study provides new insight into a treatment alternative of modified low-Dye taping for sprinter with pronated foot. Ten young male sprinters, aged 20.8±1.6 years, with pronated foot were recruited for this study. The pronated foot was defined as the foot that the navicular drop test was greater than 1.0 cm. Three optic shutters were placed at the start, 30-m, and 60-m sites to record sprint time. All participants were asked to complete 3 trials of the 60-m dash with both taping and non-taping conditions in a random order. The low-Dye taping was applied using the method postulated by Ralph Dye in 1939 except the kinesio tape was used instead. All outcome variables were recorded for taping and non-taping conditions. Paired t-tests were used to analyze all outcome variables between 2 conditions. Although there were no statistically significant differences in dorsal and plantar mobility between taping and non-taping conditions, a statistical significance was found in a total range of motion (dorsiflexion plus plantarflexion angle) of the first ray when a modified low-Dye taping was applied (p < 0.05). Time to complete 60-m sprint was significantly increased with low-Dye taping (p < 0.05) while no significance was found for time to 30-m. it indicated that modified low-Dye taping changed maximum sprint speed of 60-m dash. Conclusively, modified low-Dye taping was capable of increasing first ray mobility and further altered maximum sprint speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=first%20ray%20mobility" title="first ray mobility">first ray mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=kinesio%20taping" title=" kinesio taping"> kinesio taping</a>, <a href="https://publications.waset.org/abstracts/search?q=pronated%20foot" title=" pronated foot"> pronated foot</a>, <a href="https://publications.waset.org/abstracts/search?q=sprint%20time" title=" sprint time"> sprint time</a> </p> <a href="https://publications.waset.org/abstracts/89509/effects-of-modified-low-dye-taping-on-first-ray-mobility-test-and-sprint-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89509.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Dimensional-Controlled Functional Gold Nanoparticles and Zinc Oxide Nanorods for Solar Water Splitting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kok%20Hong%20Tan">Kok Hong Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hing%20Wah%20Lee"> Hing Wah Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhih-Wei%20Chen"> Jhih-Wei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Fu%20Dee"> Chang Fu Dee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Lin%20Wu"> Chung-Lin Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Siang-Piao%20Chai"> Siang-Piao Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Sea%20Chang"> Wei Sea Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Semiconductor photocatalyst is known as one of the key roles in developing clean and sustainable energy. However, most of the semiconductor only possesses photoactivity within the UV light region, and hence, decreases the overall photocatalyst efficiency. Generally, the overall effectiveness of the photocatalyst activity is determined by three critical steps: (i) light absorption efficiency and photoexcitation electron-hole pair generation, (ii) separation and migration of charge carriers to the surface of the photocatalyst, and (iii) surface reaction of the carriers with its environment. Much effort has been invested on optimizing hierarchical nanostructures of semiconductors for efficient photoactivity due to the fact that the visible light absorption capability and occurrence of the chemical reactions mostly depend on the dimension of photocatalysts. In this work, we incorporated zero-dimensional (0D) gold nanoparticles (AuNPs) and one dimensional (1D) Zinc Oxide (ZnO) nanorods (NRs) onto strontium titanate (STO) for efficient visible light absorption, charge transfer, and separation. We demonstrate that the electrical and optical properties of the photocatalyst can be tuned by controlling the dimensional structures of AuNPs and ZnO NRs. We found that smaller AuNPs sizes exhibited higher photoactivity because of Fermi level shifting toward the conductive band of STO, STO band gap narrowing and broadening of absorption spectrum to the visible light region. For ZnO NRs, it was found that the average ZnO NRs c-axis length must achieve of certain length to induce multiphoton absorption as a result of light reflection and trapping behavior in the free space between adjacent ZnO NRs hence broadening the absorption spectrum of ZnO from UV to visible light region. This work opens up a new way of broadening the absorption spectrum by incorporating controllable nanostructures of semiconductors, which is important in optimizing the solar water splitting process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title="gold nanoparticles">gold nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical" title=" photoelectrochemical"> photoelectrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=PEC" title=" PEC"> PEC</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor%20photocatalyst" title=" semiconductor photocatalyst"> semiconductor photocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide%20nanorods" title=" zinc oxide nanorods"> zinc oxide nanorods</a> </p> <a href="https://publications.waset.org/abstracts/92902/dimensional-controlled-functional-gold-nanoparticles-and-zinc-oxide-nanorods-for-solar-water-splitting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92902.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Probing Environmental Sustainability via Brownfield Remediation: A Framework to Manage Brownfields in Ethiopia Lesson to Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mikiale%20Gebreslase%20Gebremariam">Mikiale Gebreslase Gebremariam</a>, <a href="https://publications.waset.org/abstracts/search?q=Chai%20Huaqi"> Chai Huaqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfay%20Gebretsdkan%20Gebremichael"> Tesfay Gebretsdkan Gebremichael</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawit%20Nega%20Bekele"> Dawit Nega Bekele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, brownfield redevelopment projects (BRPs) have contributed to the overarching paradigm of the United Nations 2030 agendas. In the present circumstance, most developed nations adopted BRPs, an efficacious urban policy tool. However, in developing and some advanced countries, BRPs are lacking due to limitations of awareness, policy tools, and financial capability for cleaning up brownfield sites. For example, the growth and development of Ethiopian cities were achieved at the cost of poor urban planning, including no community consultations and excessive urbanization for future growth. The demand for land resources is more and more urgent as the result of an intermigration to major cities and towns for socio-economic reasons and population growth. In the past, the development mode of spreading major cities has made horizontal urbanizations stretching outwards. Expansion in search of more land resources, while the outer cities are growing, the inner cities are polluted by environmental pollution. It is noteworthy that the rapid development of cities has not brought about an increase in people's happiness index. Thus, the proposed management framework for managing brownfields in Ethiopia as a lesson to the developing nation facing similar challenges and growth will add immense value in solving the problems and give insights into brownfield land utilization. Under the umbrella of the grey incidence decision-making model and with the consideration of multiple stakeholders and tight environmental and economic constraints, the proposed management framework integrates different criteria from economic, social, environmental, technical, and risk aspects into the grey incidence decision-making model and gives useful guidance to manage brownfields in Ethiopia. Furthermore, it will contribute to the future development of the social economy and the missions of the 2030 UN sustainable development goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brownfields" title="Brownfields">Brownfields</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20sustainability" title=" environmental sustainability"> environmental sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=grey-incidence%20decision-making" title=" grey-incidence decision-making"> grey-incidence decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20development" title=" sustainable urban development"> sustainable urban development</a> </p> <a href="https://publications.waset.org/abstracts/151960/probing-environmental-sustainability-via-brownfield-remediation-a-framework-to-manage-brownfields-in-ethiopia-lesson-to-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151960.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> A Study of Predicting Judgments on Causes of Online Privacy Invasions: Based on U.S Judicial Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minjung%20Park">Minjung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangmi%20Chai"> Sangmi Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Myoung%20Jun%20Lee"> Myoung Jun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since there are growing concerns on online privacy, enterprises could involve various personal privacy infringements cases resulting legal causations. For companies that are involving online business, it is important for them to pay extra attentions to protect users’ privacy. If firms can aware consequences from possible online privacy invasion cases, they can more actively prevent future online privacy infringements. This study attempts to predict the probability of ruling types caused by various invasion cases under U.S Personal Privacy Act. More specifically, this research explores online privacy invasion cases which was sentenced guilty to identify types of criminal punishments such as penalty, imprisonment, probation as well as compensation in civil cases. Based on the 853 U.S judicial cases ranged from January, 2000 to May, 2016, which related on data privacy, this research examines the relationship between personal information infringements cases and adjudications. Upon analysis results of 41,724 words extracted from 853 regal cases, this study examined online users’ privacy invasion cases to predict the probability of conviction for a firm as an offender in both of criminal and civil law. This research specifically examines that a cause of privacy infringements and a judgment type, whether it leads a civil or criminal liability, from U.S court. This study applies network text analysis (NTA) for data analysis, which is regarded as a useful method to discover embedded social trends within texts. According to our research results, certain online privacy infringement cases caused by online spamming and adware have a high possibility that firms are liable in the case. Our research results provide meaningful insights to academia as well as industry. First, our study is providing a new insight by applying Big Data analytics to legal cases so that it can predict the cause of invasions and legal consequences. Since there are few researches applying big data analytics in the domain of law, specifically in online privacy, this study suggests new area that future studies can explore. Secondly, this study reflects social influences, such as a development of privacy invasion technologies and changes of users’ level of awareness of online privacy on judicial cases analysis by adopting NTA method. Our research results indicate that firms need to improve technical and managerial systems to protect users’ online privacy to avoid negative legal consequences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20text%20analysis" title="network text analysis">network text analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20privacy%20invasions" title=" online privacy invasions"> online privacy invasions</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20information%20infringements" title=" personal information infringements"> personal information infringements</a>, <a href="https://publications.waset.org/abstracts/search?q=predicting%20judgements" title=" predicting judgements"> predicting judgements</a> </p> <a href="https://publications.waset.org/abstracts/56304/a-study-of-predicting-judgments-on-causes-of-online-privacy-invasions-based-on-us-judicial-cases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56304.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Knowledge, Attitude and Practice on Swimming Pool Hygiene and Assessment of Microbial Contamination in Educational Institution in Selangor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zarini%20Ismail">Zarini Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mas%20Ayu%20Arina%20Mohd%20Anuwar"> Mas Ayu Arina Mohd Anuwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ling%20Chai%20Ying"> Ling Chai Ying</a>, <a href="https://publications.waset.org/abstracts/search?q=Tengku%20Zetty%20Maztura%20Tengku%20Jamaluddin"> Tengku Zetty Maztura Tengku Jamaluddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Azmawati%20Mohamed"> Nurul Azmawati Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadeeya%20Ayn%20Umaisara%20Mohamad%20Nor"> Nadeeya Ayn Umaisara Mohamad Nor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transmission of infectious diseases can occur anywhere, including in the swimming pools. A large number of swimmers turnover and poor hygienic behaviours will increase the occurrence of direct and indirect water contamination. A wide variety of infections such as the gastrointestinal illnesses, skin rash, eye infections, ear infections and respiratory illnesses had been reported following the exposure to the contaminated water. Understanding the importance of pool hygiene with a healthy practice will reduce the risk of infection. The aims of the study are to investigate the knowledge, attitude and practices on pool hygiene among swimming pool users and to determine the microbial contaminants in swimming pools. A cross-sectional study was conducted using self-administered questionnaires to 600 swimming pool users from four swimming pools belong to the three educational institutions in Selangor. Data was analyzed using SPSS Statistics version 22.0 for Windows. The knowledge, attitude and practice of the study participants were analyzed using the sum score based on Bloom’s cut-off point (80%). Having a score above the cut-off point was classified as having high levels of knowledge, positive attitude and good practice. The association between socio-demographic characteristics, knowledge and attitude with practice on pool hygiene was determined by Chi-Square test. The physicochemical parameters and the microbial contamination were determined using a standard method for examination of waste and wastewater. Of the 600 respondents, 465 (77.5%) were females with the mean age of 21 years old. Most of the respondents are the students (98.8%) which belong to the three educational institutions in Selangor. Overall, the majority of the respondents (89.2%) had low knowledge on pool hygiene, but had positive attitudes (91.3%). Whereas only half of the respondents (50%) practice good hygiene while using the swimming pools. There was a significant association between practice level on pool hygiene with knowledge (p < 0.001) and also the attitude (p < 0.001). The measurements of the physicochemical parameters showed that all 4 swimming pools had low levels of pH and two had low levels of free chlorine. However, all the water samples tested were negative for Escherichia coli. The findings of this study suggested that high knowledge and positive attitude towards pool hygiene ensure a good practice among swimming pool users.

The study is targeted on Internet users, and the value of their private information will be converted into economic figures. Moreover, how economic value changes in relation with individual attributes, dealer’s traits, circumstantial properties will be studied. In this research, the changes in factors on private information value responding to different situations will be analyzed in an economic perspective. Additionally, this study examines the associations between users’ perceived risk and value of their personal information. By using the cost-benefit analysis framework, the hypothesis that the user’s sense in private information value can be influenced by individual attributes and situational properties will be tested. Therefore, this research will attempt to provide answers for three research objectives. First, this research will identify factors that affect value recognition of users’ personal information. Second, it provides evidences that there are differences on information system users’ economic value of information responding to personal, trade opponent, and situational attributes. Third, it investigates the impact of those attributes on individuals’ perceived risk. Based on the assumption that personal, trade opponent and situation attributes make an impact on the users’ value recognition on private information, this research will present the understandings on the different impacts of those attributes in recognizing the value of information with the economic perspective and prove the associative relationships between perceived risk and decision on the value of users’ personal information. In order to validate our research model, this research used the regression methodology. Our research results support that information breach experience and information security systems is associated with users’ perceived risk. Information control and uncertainty are also related to users’ perceived risk. Therefore, users’ perceived risk is considered as a significant factor on evaluating the value of personal information. It can be differentiated by trade opponent and situational attributes. This research presents new perspective on evaluating the value of users’ personal information in the context of perceived risk, personal, trade opponent and situational attributes. It fills the gap in the literature by providing how users’ perceived risk are associated with personal, trade opponent and situation attitudes in conducting business transactions with providing personal information. It adds to previous literature that the relationship exists between perceived risk and the value of users’ private information in the economic perspective. It also provides meaningful insights to the managers that in order to minimize the cost of information breach, managers need to recognize the value of individuals’ personal information and decide the proper amount of investments on protecting users’ online information privacy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=private%20information" title="private information">private information</a>, <a href="https://publications.waset.org/abstracts/search?q=value" title=" value"> value</a>, <a href="https://publications.waset.org/abstracts/search?q=users" title=" users"> users</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20risk" title=" perceived risk"> perceived risk</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20information%20privacy" title=" online information privacy"> online information privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=attributes" title=" attributes"> attributes</a> </p> <a href="https://publications.waset.org/abstracts/56324/evaluating-value-of-users-personal-information-based-on-cost-benefit-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56324.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Development of Structural Deterioration Models for Flexible Pavement Using Traffic Speed Deflectometer Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sittampalam%20Manoharan">Sittampalam Manoharan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gary%20Chai"> Gary Chai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanaul%20Chowdhury"> Sanaul Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Golding"> Andrew Golding</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary objective of this paper is to present a simplified approach to develop the structural deterioration model using traffic speed deflectometer data for flexible pavements. Maintaining assets to meet functional performance is not economical or sustainable in the long terms, and it would end up needing much more investments for road agencies and extra costs for road users. Performance models have to be included for structural and functional predicting capabilities, in order to assess the needs, and the time frame of those needs. As such structural modelling plays a vital role in the prediction of pavement performance. A structural condition is important for the prediction of remaining life and overall health of a road network and also major influence on the valuation of road pavement. Therefore, the structural deterioration model is a critical input into pavement management system for predicting pavement rehabilitation needs accurately. The Traffic Speed Deflectometer (TSD) is a vehicle-mounted Doppler laser system that is capable of continuously measuring the structural bearing capacity of a pavement whilst moving at traffic speeds. The device’s high accuracy, high speed, and continuous deflection profiles are useful for network-level applications such as predicting road rehabilitations needs and remaining structural service life. The methodology adopted in this model by utilizing time series TSD maximum deflection (D0) data in conjunction with rutting, rutting progression, pavement age, subgrade strength and equivalent standard axle (ESA) data. Then, regression analyses were undertaken to establish a correlation equation of structural deterioration as a function of rutting, pavement age, seal age and equivalent standard axle (ESA). This study developed a simple structural deterioration model which will enable to incorporate available TSD structural data in pavement management system for developing network-level pavement investment strategies. Therefore, the available funding can be used effectively to minimize the whole –of- life cost of the road asset and also improve pavement performance. This study will contribute to narrowing the knowledge gap in structural data usage in network level investment analysis and provide a simple methodology to use structural data effectively in investment decision-making process for road agencies to manage aging road assets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjusted%20structural%20number%20%28SNP%29" title="adjusted structural number (SNP)">adjusted structural number (SNP)</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20deflection%20%28D0%29" title=" maximum deflection (D0)"> maximum deflection (D0)</a>, <a href="https://publications.waset.org/abstracts/search?q=equant%20standard%20axle%20%28ESA%29" title=" equant standard axle (ESA)"> equant standard axle (ESA)</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20speed%20deflectometer%20%28TSD%29" title=" traffic speed deflectometer (TSD)"> traffic speed deflectometer (TSD)</a> </p> <a href="https://publications.waset.org/abstracts/88655/development-of-structural-deterioration-models-for-flexible-pavement-using-traffic-speed-deflectometer-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88655.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Interfacial Instability and Mixing Behavior between Two Liquid Layers Bounded in Finite Volumes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Li">Lei Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20M.%20Chai"> Ming M.

Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mixing process of two liquid layers in a cylindrical container includes the upper liquid with higher density rushing into the lower liquid with lighter density, the lower liquid rising into the upper liquid, meanwhile the two liquid layers having interactions with each other, forming vortices, spreading or dispersing in others, entraining or mixing with others. It is a complex process constituted of flow instability, turbulent mixing and other multiscale physical phenomena and having a fast evolution velocity. In order to explore the mechanism of the process and make further investigations, some experiments about the interfacial instability and mixing behavior between two liquid layers bounded in different volumes are carried out, applying the planar laser induced fluorescence (PLIF) and the high speed camera (HSC) techniques. According to the results, the evolution of interfacial instability between immiscible liquid develops faster than theoretical rate given by the Rayleigh-Taylor Instability (RTI) theory. It is reasonable to conjecture that some mechanisms except the RTI play key roles in the mixture process of two liquid layers. From the results, it is shown that the invading velocity of the upper liquid into the lower liquid does not depend on the upper liquid's volume (height). Comparing to the cases that the upper and lower containers are of identical diameter, in the case that the lower liquid volume increases to larger geometric space, the upper liquid spreads and expands into the lower liquid more quickly during the evolution of interfacial instability, indicating that the container wall has important influence on the mixing process. In the experiments of miscible liquid layers’ mixing, the diffusion time and pattern of the liquid interfacial mixing also does not depend on the upper liquid's volumes, and when the lower liquid volume increases to larger geometric space, the action of the bounded wall on the liquid falling and rising flow will decrease, and the liquid interfacial mixing effects will also attenuate. Therefore, it is also concluded that the volume weight of upper heavier liquid is not the reason of the fast interfacial instability evolution between the two liquid layers and the bounded wall action is limited to the unstable and mixing flow. The numerical simulations of the immiscible liquid layers’ interfacial instability flow using the VOF method show the typical flow pattern agree with the experiments. However the calculated instability development is much slower than the experimental measurement. The numerical simulation of the miscible liquids’ mixing, which applying Fick’s diffusion law to the components’ transport equation, shows a much faster mixing rate than the experiments on the liquids’ interface at the initial stage. It can be presumed that the interfacial tension plays an important role in the interfacial instability between the two liquid layers bounded in finite volume. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfacial%20instability%20and%20mixing" title="interfacial instability and mixing">interfacial instability and mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20liquid%20layers" title=" two liquid layers"> two liquid layers</a>, <a href="https://publications.waset.org/abstracts/search?q=Planar%20Laser%20Induced%20Fluorescence%20%28PLIF%29" title=" Planar Laser Induced Fluorescence (PLIF)"> Planar Laser Induced Fluorescence (PLIF)</a>, <a href="https://publications.waset.org/abstracts/search?q=High%20Speed%20Camera%20%28HSC%29" title=" High Speed Camera (HSC)"> High Speed Camera (HSC)</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20energy%20and%20tension" title=" interfacial energy and tension"> interfacial energy and tension</a>, <a href="https://publications.waset.org/abstracts/search?q=Cahn-Hilliard%20Navier-Stokes%20%28CHNS%29%20equations" title=" Cahn-Hilliard Navier-Stokes (CHNS) equations"> Cahn-Hilliard Navier-Stokes (CHNS) equations</a> </p> <a href="https://publications.waset.org/abstracts/68285/interfacial-instability-and-mixing-behavior-between-two-liquid-layers-bounded-in-finite-volumes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Constitutive Androstane Receptor (CAR) Inhibitor CINPA1 as a Tool to Understand CAR Structure and Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milu%20T.%20Cherian">Milu T.

CAR and PXR are xenobiotic sensors that respond to drugs and endobiotics by modulating the expression of metabolic genes that enhance detoxification and elimination. Elevated levels of drug metabolizing enzymes and efflux transporters resulting from CAR activation promote the elimination of chemotherapeutic agents leading to reduced therapeutic effectiveness. Multidrug resistance in tumors after chemotherapy could be associated with errant CAR activity, as shown in the case of neuroblastoma. CAR inhibitors used in combination with existing chemotherapeutics could be utilized to attenuate multidrug resistance and resensitize chemo-resistant cancer cells. CAR and PXR have many overlapping modulating ligands as well as many overlapping target genes which confounded attempts to understand and regulate receptor-specific activity. Through a directed screening approach we previously identified a new CAR inhibitor, CINPA1, which is novel in its ability to inhibit CAR function without activating PXR. The cellular mechanisms by which CINPA1 inhibits CAR function were also extensively examined along with its pharmacokinetic properties. CINPA1 binding was shown to change CAR-coregulator interactions as well as modify CAR recruitment at DNA response elements of regulated genes. CINPA1 was shown to be broken down in the liver to form two, mostly inactive, metabolites. The structure-activity differences of CINPA1 and its metabolites were used to guide computational modeling using the CAR-LBD structure. To rationalize how ligand binding may lead to different CAR pharmacology, an analysis of the docked poses of human CAR bound to CITCO (a CAR activator) vs. CINPA1 or the metabolites was conducted. From our modeling, strong hydrogen bonding of CINPA1 with N165 and H203 in the CAR-LBD was predicted. These residues were validated to be important for CINPA1 binding using single amino-acid CAR mutants in a CAR-mediated functional reporter assay. Also predicted were residues making key hydrophobic interactions with CINPA1 but not the inactive metabolites. Some of these hydrophobic amino acids were also identified and additionally, the differential coregulator interactions of these mutants were determined in mammalian two-hybrid systems. CINPA1 represents an excellent starting point for future optimization into highly relevant probe molecules to study the function of the CAR receptor in normal- and pathophysiology, and possible development of therapeutics (for e.g. use for resensitizing chemoresistant neuroblastoma cells). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antagonist" title="antagonist">antagonist</a>, <a href="https://publications.waset.org/abstracts/search?q=chemoresistance" title=" chemoresistance"> chemoresistance</a>, <a href="https://publications.waset.org/abstracts/search?q=constitutive%20androstane%20receptor%20%28CAR%29" title=" constitutive androstane receptor (CAR)"> constitutive androstane receptor (CAR)</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-drug%20resistance" title=" multi-drug resistance"> multi-drug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20activity%20relationship%20%28SAR%29" title=" structure activity relationship (SAR)"> structure activity relationship (SAR)</a>, <a href="https://publications.waset.org/abstracts/search?q=xenobiotic%20resistance" title=" xenobiotic resistance"> xenobiotic resistance</a> </p> <a href="https://publications.waset.org/abstracts/64478/constitutive-androstane-receptor-car-inhibitor-cinpa1-as-a-tool-to-understand-car-structure-and-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64478.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> [Keynote Talk]: Surveillance of Food Safety Compliance of Hong Kong Street Food</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mabel%20Y.%20C.%20Yau">Mabel Y.

The study reflects similar situations in running mobile food vending business on trucks. Hong Kong is about to launch the Food Truck Pilot Scheme by the end of 2016 or early 2017. Technically, selling food on the vehicle is no different from hawking food on the street or vending food on the street. Each type of business bears similar food safety issues and cast the same impact on public health. Present findings demonstrate exemplarily situations that also apply to food trucks. 9 types of Cantonese style snacks of 32 samples in total were selected for microbial screening. A total of 16 vending sites including supermarkets, street markets, and snack stores were visited. The study finally focused on a traditional snack, the steamed rice cake with red beans called Put Chai Ko (PCK). PCK is a type of classical Cantonese pastry sold on push carts on the street. It used to be sold at room temperature and served with bamboo sticks in the old days. Some shops would have them sold steam fresh. Microbial examinations on aerobic counts, yeast, and mould, coliform, salmonella as well as Staphylococcus aureus detections were carried out. Salmonella was not detected in all samples. Since PCK does not contain ingredients of beef, poultry, eggs or dairy products, the risk of the presence of Salmonella in PCK was relatively lower although other source of contamination might be possible. Coagulase positive Staphylococcus aureus was found in 6 of the 14 samples sold at room temperature. Among these 6 samples, 3 were PCK. One of the samples was in an unacceptable range of total colony forming units higher than 105. The rest were only satisfactory. Observational evaluations were made with checklists on personal hygiene, premises hygiene, food safety control, food storage, cleaning and sanitization as well as waste disposals. The maximum score was 25 if total compliance were obtained. The highest score among vendors was 20. Three stores were below average, and two of these stores were selling PCK. Most of the non-compliances were on food processing facilities, sanitization conditions and waste disposal. In conclusion, although no food poisoning outbreaks happened during the time of the investigation, the risk of food hazard existed in these stores, especially among street vendors. Attention is needed in the traditional practice of food selling, and that food handlers might not have sufficient knowledge to properly handle food products. Variations in food qualities existed among supply chains or franchise eateries or shops. It was commonly observed that packaging and storage conditions are not properly enforced in the retails. The same situation could be reflected across the food business. It did indicate need of food safety training in the industry and loopholes in quality control among business. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cantonese%20snacks" title="cantonese snacks">cantonese snacks</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial" title=" microbial"> microbial</a>, <a href="https://publications.waset.org/abstracts/search?q=hygiene" title=" hygiene"> hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=street%20food" title=" street food"> street food</a> </p> <a href="https://publications.waset.org/abstracts/57554/keynote-talk-surveillance-of-food-safety-compliance-of-hong-kong-street-food" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57554.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
