Hanmin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wong Kar-Wai’s multi-genre film 2046, world premiered in 2004, comes with a vibrant mediascape made up of multiple named languages, code-switching, intertitles, news footage from the real world, and extra-linguistic means of communication. In film- and multilingual studies it is still a challenge to incorporate non-languages into an analytical framework with conventional languages. This paper uses translanguaging theory to read silent practices in Wong Kar-Wai’ 2046. Two scenes that feature the silence experience the most are taken as case studies. In these two scenes, we can identify two tropes of intersemiotic relationships that are co-articulated by silence: patriarchy and unfinished romance, respectively. The conclusion argues that silence in Wong Kar-Wai’s 2046 exerts multimodal agency by ‘speaking’ directly to the audience and in mutual directions to characters. Thereby, it moves beyond the passive role of merely accentuating or assisting the aural register of a film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=translanguaging" title="translanguaging">translanguaging</a>, <a href="https://publications.waset.org/abstracts/search?q=Wong%20Kar-Wai" title=" Wong Kar-Wai"> Wong Kar-Wai</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodality" title=" multimodality"> multimodality</a>, <a href="https://publications.waset.org/abstracts/search?q=semiotics" title=" semiotics"> semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=inter%20semiotics" title=" inter semiotics"> inter semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Kong%20media" title=" Hong Kong media"> Hong Kong media</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20culture" title=" film culture"> film culture</a> </p> <a href="https://publications.waset.org/abstracts/163911/silence-the-silence-no-more-a-translanguaging-analysis-of-two-silent-scenes-in-wong-kar-wais-multi-genre-film-2046" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163911.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">103</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">181</span> Bubble Point Pressures of CO2+Ethyl Palmitate by a Cubic Equation of State and the Wong-Sandler Mixing Rule</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Sedghamiz">M.

Raeissi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents three different approaches to estimate bubble point pressures for the binary system of CO2 and ethyl palmitate fatty acid ethyl ester. The first method involves the Peng-Robinson (PR) Equation of State (EoS) with the conventional mixing rule of Van der Waals. The second approach involves the PR EOS together with the Wong Sandler (WS) mixing rule, coupled with the Uniquac Ge model. In order to model the bubble point pressures with this approach, the volume and area parameter for ethyl palmitate were estimated by the Hansen group contribution method. The last method involved the Peng-Robinson, combined with the Wong-Sandler Method, but using NRTL as the GE model. Results using the Van der Waals mixing rule clearly indicated that this method has the largest errors among all three methods, with errors in the range of 3.96–6.22 %. The Pr-Ws-Uniquac method exhibited small errors, with average absolute deviations between 0.95 to 1.97 percent. The Pr-Ws-Nrtl method led to the least errors where average absolute deviations ranged between 0.65-1.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bubble%20pressure" title="bubble pressure">bubble pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Gibbs%20excess%20energy%20model" title=" Gibbs excess energy model"> Gibbs excess energy model</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing%20rule" title=" mixing rule"> mixing rule</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20solubility" title=" CO2 solubility"> CO2 solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=ethyl%20palmitate" title=" ethyl palmitate"> ethyl palmitate</a> </p> <a href="https://publications.waset.org/abstracts/2308/bubble-point-pressures-of-co2ethyl-palmitate-by-a-cubic-equation-of-state-and-the-wong-sandler-mixing-rule" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2308.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">474</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">180</span> Recent Studies on Strengthening of Reinforced Concrete Members by Ferrocement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Lam">E.

Using mortar in ferrocement with high tensile strength, tensile properties of (high performance) ferrocement can be enhanced. In the proposed strengthening strategy, defective concrete cover of structural members is replaced by ferrocement so as to increase the load carrying capacity. This has been successfully applied to strengthen columns and beam-column joints. To facilitate the ease of application of the proposed strengthening strategy, mortar in ferrocement is applied through dry spray shotcrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferrocement" title="ferrocement">ferrocement</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20ferrocement" title=" high performance ferrocement"> high performance ferrocement</a>, <a href="https://publications.waset.org/abstracts/search?q=dry" title=" dry"> dry</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20shotcrete" title=" spray shotcrete"> spray shotcrete</a>, <a href="https://publications.waset.org/abstracts/search?q=column" title=" column"> column</a>, <a href="https://publications.waset.org/abstracts/search?q=beam-column%20joint" title=" beam-column joint"> beam-column joint</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a> </p> <a href="https://publications.waset.org/abstracts/17783/recent-studies-on-strengthening-of-reinforced-concrete-members-by-ferrocement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17783.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">443</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">179</span> Genres as Time Machines: Hong Kong Cinema's Ways of Historicizing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chin%20Pang%20Lei">Chin Pang Lei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Colonized by the UK, handed over to China, and now as a global financial city, Hong Kong’s history is never easy to write under the dominant discourses of colonialism, nationalism and globalization. In this plight, cinema, regarded as Hong Kong’s most representative cultural form, is used for writing, exploring and questioning the local history of the city. In their writing of the past, Hong Kong directors such as Wong Kar-wai, Stanley Kwan and Tsui Hark have demonstrated alternative ways of historicizing Hong Kong. Despite their interests in different periods of time (Wong is obsessed with the 1960s; Kwan is attracted to the 1930s; Tsui often goes back to the early 20th century), all these directors use genres as their time machines to revisit the past. As a popular cultural form, genres always come with a series of ideologies which define our lives and explain the society. Hence, in a changing society, genres change and complicate themselves with different packages of meanings. Genres function as open-ended and corrigible schemata which can contain multiple themes and various meanings. In Hong Kong, genres, often seen as highly commercial and overly market-oriented, are opportunities for alternative history writing and the exploration of local identities. This paper examines how these Hong Kong directors use the popular forms of genres, such as melodrama, martial art and gangster films, to present the past, and how the stories of the fictional characters, such as prostitutes, martial artists and jobless hooligans mobilize imagination of history. These texts show that genre is a crucial platform for Hong Kong’s post-colonial self-writing. Via genres, history in these films is against official and canonical history as well as grand narrative. Genres as time machines articulate a voice for Hong Kong. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Kong%20cinema" title="Hong Kong cinema">Hong Kong cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=genre" title=" genre"> genre</a>, <a href="https://publications.waset.org/abstracts/search?q=historicizing" title=" historicizing"> historicizing</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20history" title=" local history"> local history</a>, <a href="https://publications.waset.org/abstracts/search?q=Wong%20Kar-Wai" title=" Wong Kar-Wai"> Wong Kar-Wai</a> </p> <a href="https://publications.waset.org/abstracts/86950/genres-as-time-machines-hong-kong-cinemas-ways-of-historicizing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86950.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">366</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">178</span> A Framework for Internet Education: Personalised Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zoe%20Wong">Zoe Wong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to develop a framework for internet education.

The proposed PV balancer senses the voltage and current of PV module and adjusts the output voltage of converter. Thus, the PV system can implement maximum power point tracking (MPPT) independently for each module whether it is under shading, different irradiation or degradation of PV cell. In addition, the cost of PV balancer can be reduced due to the low power rating of converter. To assess the effectiveness of the proposed system, two PV balancers are designed and verified through simulation under different shading conditions. The proposed PV balancers can provide more energy than the traditional PV balancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MPPT" title="MPPT">MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20shading" title=" partial shading"> partial shading</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20System" title=" PV System"> PV System</a>, <a href="https://publications.waset.org/abstracts/search?q=converter" title=" converter"> converter</a> </p> <a href="https://publications.waset.org/abstracts/56905/an-improved-photovolatic-system-balancer-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56905.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">291</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">174</span> Visualization of Malaysia Universities Websites Based On Social Network Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20A.%20Ismail">N.

The 7.5 million residents of this mature and busy metropolis are living in a primarily high-rise city whereby development and renewal of the cityscape are taking place unceasingly. Hong Kong residents are therefore affected by the virtually continuous and numerous construction activities. In 2020, the Hong Kong environmental protection department (EPD) completed a feasibility study on managing construction noise, including those associated with the renovation of domestic premises. Part of the study was the review of management and control of construction noise in other metropolitan cities globally. As far as the authors are aware of, such worldwide and extensive review of best practices on construction noise control has not been conducted for over 20 years. In order to benefit from international best practices, the extensive review is to identify possible areas for improvement in Hong Kong. The consultant of the study first referred to the United Nations Report ‘The World’s Cities in 2016’ and examined the top 100 cities therein. The 20 most suitable cities were then chosen for further review. Upon screening of each of these 20 cities, 12 cities with the more relevant management practices were selected for further scrutiny. These 12 cities were: Asia – Tokyo, Seoul, Taipei, Guangzhou, Singapore; Europe – City of Westminster (London), Berlin; North America – Toronto, New York City, San Francisco; Oceania – Sydney, Melbourne. Afterwards, three cities, namely Sydney, City of Westminster, and New York City, were selected for in-depth review. These cities were chosen primarily because of the maturity, success, and effectiveness of their construction noise management and control measures, as well as their similarity to Hong Kong in key and selected aspects. One of the more important findings of the review is the usefulness of early focus, with the aim of designing the noise issues away wherever practicable. The consultant examined the similar yet different construction noise early focus mechanisms of the three cities. This paper describes this landmark worldwide and extensive review of international best practices on construction noise management and control. The methodology, approach, and key findings are presented to give readers a succinct yet comprehensive view. The authors shared the findings with the acoustics professionals worldwide with the hope of global advancement of more mature construction noise management while welcoming sustainable development and construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20noise" title="construction noise">construction noise</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20best%20practices" title=" international best practices"> international best practices</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20control" title=" noise control"> noise control</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20management" title=" noise management"> noise management</a> </p> <a href="https://publications.waset.org/abstracts/138585/construction-noise-control-hong-kong-reviews-international-best-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138585.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">137</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">172</span> A Cohort and Empirical Based Multivariate Mortality Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Tzu-Hao%20Tsai">Jeffrey Tzu-Hao Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Shan%20Wong"> Yi-Shan Wong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article proposes a cohort-age-period (CAP) model to characterize multi-population mortality processes using cohort, age, and period variables.

The model not only provides a fruitful intuition for explaining multivariate mortality change rates but also has a better performance in forecasting future patterns.

Specifically, it aimed to: 1. Identify the appropriate Instructional Systems Design (ISD) model in the development of the courseware material; 2. Assess the courseware material according to its: a. Content Characteristics; b. Instructional Characteristics; and c. Technical Characteristics 3. Find out if there is a significant difference in the performance of students before and after using the tutorial CAI. This research is developmental as well as a one group pretest-posttest design. The study had two phases. Phase I includes the needs analysis, writing of lessons and storyboard by the respective experts in each field. Phase II includes the digitization or the actual development of the courseware by the faculty of the ICT department. In this phase it adapted an instructional systems design (ISD) model which is the ADDIE model. ADDIE stands for Analysis, Design, Development, Implementation and Evaluation. Formative evaluation was conducted simultaneously with the different phases to detect and remedy any bugs in the courseware along the areas of content, instructional and technical characteristics. The expected output are the digitized lessons in Algebra, Biology, Chemistry, Physics and Communication Arts in English. Students and some IT experts validated the CAI material using the Evaluation Form by Wong & Wong. They validated the CAI materials as Highly Acceptable with an overall mean rating of 4.527and standard deviation of 0 which means that they were one in the ratings they have given the CAI materials. A mean gain was recorded and computing the t-test for dependent samples it showed that there were significant differences in the mean achievement of the students before and after the treatment (using CAI). The identified ISD model used in the development of the tutorial courseware was the ADDIE model. The quantitative analyses of data based on ratings given by the respondents’ shows that the tutorial courseware possess the characteristics and or qualities of a very good computer-based courseware. The ratings given by the different evaluators with regard to content, instructional, and technical aspects of the Tutorial Courseware are in conformity towards being excellent. Students performed better in mathematics, biology chemistry, physics and the English Communication Arts after they were exposed to the tutorial courseware. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAI" title="CAI">CAI</a>, <a href="https://publications.waset.org/abstracts/search?q=tutorial%20courseware" title=" tutorial courseware"> tutorial courseware</a>, <a href="https://publications.waset.org/abstracts/search?q=Instructional%20Systems%20Design%20%28ISD%29%20Model" title=" Instructional Systems Design (ISD) Model"> Instructional Systems Design (ISD) Model</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a> </p> <a href="https://publications.waset.org/abstracts/8852/development-of-tutorial-courseware-on-selected-topics-in-mathematics-science-and-the-english-language" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8852.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">346</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">168</span> The Compliance of Safe-Work Behaviors among Undergraduate Nursing Students with Different Clinical Experiences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20C.%20Wong">K.

Likewise, undergraduate nursing students are also exposed to potential safety hazard due to their similar work nature of registered nurses. Especially, those students who worked as Temporary undergraduate nursing students (TUNS) which is a part-time clinical job in hospitals in Hong Kong who mainly assisted in providing bedside cares appeared to at high risk of work-related injuries. Several studies suggested the level of compliance with safe work behaviors was highly associated with work-related injuries. Yet, it had been limitedly studied among nursing students. This study was conducted to assess and compare the compliance with safe work behaviors and the levels of awareness of different workplace safety issues between undergraduate nursing students with or without TUNS experiences. Methods: This is a quantitative descriptive study using convenience sampling. 362 undergraduate nursing students in Hong Kong were recruited. The Safe Work Behavior relating to Patient Handling (SWB-PH) was used to assess their compliance of safe-work behaviors and the level of awareness of different workplace safety issues. Results: The results showed that most of the participants (n=250, 69.1%) who were working as TUNS. However, students who worked as TUNS had significantly lower safe-work behaviors compliance (mean SWB-PH score = 3.64±0.54) than those did not worked as TUNS (SWB-PH score=4.21±0.54) (p<0.001). Particularly, these students had higher awareness to seek help and use assistive devices but lower awareness of workplace safety issues and awareness of proper work posture than students without TUNS experiences. The students with TUNS experiences had higher engagement in help-seeking behaviors might be possibly explained by their richer clinical experiences which served as a facilitator to seek help from clinical staff whenever necessary. Besides, these experienced students were more likely to bear risks for occupational injuries and worked alone when no available aid which might be related to the busy working environment, heightened work pressures and high expectations of TUNS. Eventually, students who worked as TUNS might target on completing the assigned tasks and gradually neglecting the occupational safety. Conclusion: The findings contributed to an understanding of the level of compliance with safe work behaviors among nursing students with different clinical experiences. The results might guide the modification of current safety protocols and the introduction of multiple clinical training courses to improve nursing student’s engagement in safe work behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Occupational%20safety" title="Occupational safety">Occupational safety</a>, <a href="https://publications.waset.org/abstracts/search?q=Safety%20compliance" title=" Safety compliance"> Safety compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=Safe-work%20behavior" title=" Safe-work behavior"> Safe-work behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=Nursing%20students" title=" Nursing students"> Nursing students</a> </p> <a href="https://publications.waset.org/abstracts/128239/the-compliance-of-safe-work-behaviors-among-undergraduate-nursing-students-with-different-clinical-experiences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128239.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">144</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">167</span> Development of Soft 3D Printing Materials for Textile Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Chung%20Marven%20Chick">Chi-Chung Marven Chick</a>, <a href="https://publications.waset.org/abstracts/search?q=Chu-Po%20Ho"> Chu-Po Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Sau-Chuen%20Joe%20Au"> Sau-Chuen Joe Au</a>, <a href="https://publications.waset.org/abstracts/search?q=Wing-Fai%20Sidney%20Wong"> Wing-Fai Sidney Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Wai%20Kan"> Chi-Wai Kan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, 3D printing becomes popular process for manufacturing, especially has special attention in textile applications. However, there are various types of 3D printing materials, including plastic, resin, rubber, ceramics, gold, platinum, silver, iron, titanium but not all these materials are suitable for textile application. Generally speaking, 3D printing of textile mainly uses thermoplastic polymers such as acrylonitrile butadiene styrene (ABS), polylactide (PLA), polycaprolactone (PCL), thermoplastic polyurethane (TPU), polyethylene terephthalate glycol-modified (PETG), polystyrene (PS), polypropylene (PP). Due to the characteristics of the polymers, 3D printed textiles usually have low air permeability and poor comfortable. Therefore, in this paper, we will review the possible materials suitable for textile application with desired physical and mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing%20materials" title=" 3D printing materials"> 3D printing materials</a>, <a href="https://publications.waset.org/abstracts/search?q=textile" title=" textile"> textile</a>, <a href="https://publications.waset.org/abstracts/search?q=properties" title=" properties"> properties</a> </p> <a href="https://publications.waset.org/abstracts/184118/development-of-soft-3d-printing-materials-for-textile-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184118.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">63</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">166</span> Design Aspects of 3D Printing for Fashion and Textiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Chung%20Marven%20Chick">Chi-Chung Marven Chick</a>, <a href="https://publications.waset.org/abstracts/search?q=Chu-Po%20Ho"> Chu-Po Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Sau-Chuen%20Joe%20Au"> Sau-Chuen Joe Au</a>, <a href="https://publications.waset.org/abstracts/search?q=Wing-Fai%20Sidney%20Wong"> Wing-Fai Sidney Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Wai%20Kan"> Chi-Wai Kan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 3D printing is now drawing attention to manufacturing process.

In term of fire resistance, cross-laminated timber panels are promoted as having excellent fire resistance, comparable to that of non-combustible materials and to heavy timber construction, due to the ability of thick wood assemblies to char slowly at a predictable rate while maintaining most of their strength during the fire exposure. This paper presents an overview of fire performance of cross-laminated timber and evaluation of its resistance to elevated temperature in comparison to homogeneous timber panels. Charring rates for cross-laminated timber panels of those obtained experimentally were compared with those provided by Eurocode simplified calculation methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=timber%20structure" title="timber structure">timber structure</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-laminated%20timber" title=" cross-laminated timber"> cross-laminated timber</a>, <a href="https://publications.waset.org/abstracts/search?q=charring%20rate" title=" charring rate"> charring rate</a>, <a href="https://publications.waset.org/abstracts/search?q=timber%20fire%20resistance" title=" timber fire resistance"> timber fire resistance</a> </p> <a href="https://publications.waset.org/abstracts/7520/the-fire-performance-of-exposed-timber-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7520.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">415</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">164</span> Mechanisms Underlying the Effects of School-Based Internet Intervention for Alcohol Drinking Behaviours among Chinese Adolescent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keith%20T.%20S.%20Tung">Keith T.

Conventional prevention/intervention relies on unidirectional knowledge transfer such as mail leaflets or health talks which showed mixed results in changing the target behaviour. Previously, we conducted a school internet-based intervention which was found to be effective in reducing alcohol use among adolescents, yet the underlying mechanisms have not been properly investigated. This study, therefore, examined the mechanisms that explain how the intervention produced a change in alcohol drinking behaviours among Chinese adolescent as observed in our previous clustered randomised controlled trial (RCT) study. Methods: This is a cluster randomised controlled trial with parallel group design. Participating schools were randomised to the Internet intervention or the conventional health education group (control) with a 1:1 allocation ratio. Secondary 1–3 students of the participating schools were enrolled in this study. The Internet intervention was a web-based quiz game competition, in which participating students would answer 1,000 alcohol-related multiple-choice quiz questions. Conventional health education group received a promotional package on equivalent alcohol-related knowledge. The participants’ alcohol-related attitude, knowledge, and perceived behavioural control were self-reported before the intervention (baseline) and one month and three months after the intervention. Results: Our RCT results showed that participants in the Internet group were less likely to drink (risk ratio [RR] 0.79, p < 0.01) as well as in lesser amount (β -0.06, p < 0.05) compared to those in the control group at both post-intervention follow-ups. Within the intervention group, regression analyses showed that high quiz scorer had greater improvement in alcohol-related knowledge (β 0.28, p < 0.01) and attitude (β -0.26, p < 0.01) at 1 month after intervention, which in turn increased their perceived behavioural control against alcohol use (β 0.10 and -0.26, both p < 0.01). Attitude, compared to knowledge, was found to be a stronger contributor to the intervention effect on perceived behavioural control. Conclusions: Our internet-based intervention has demonstrated effectiveness in reducing the risk of underage drinking when compared with conventional health education. Our study results further showed an attitude to be a more important factor than knowledge in changing health-related behaviour. This has an important implication for future prevention/intervention on an underage drinking problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescents" title="adolescents">adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=internet-based%20intervention" title=" internet-based intervention"> internet-based intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=randomized%20controlled%20trial" title=" randomized controlled trial"> randomized controlled trial</a>, <a href="https://publications.waset.org/abstracts/search?q=underage%20drinking" title=" underage drinking"> underage drinking</a> </p> <a href="https://publications.waset.org/abstracts/112258/mechanisms-underlying-the-effects-of-school-based-internet-intervention-for-alcohol-drinking-behaviours-among-chinese-adolescent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112258.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">163</span> Innovative Pictogram Chinese Characters Representation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Low">J.

But it is hard to identify the related issues or to distinguish them. Although the similarity between the issues cannot be identified, but with the R&D lexicon, the issues that always shared the same R&D keywords can be determined. In details, the R&D keywords that associated with particular issue is implied the key technology elements that needed to solve the problem of the particular issue. Furthermore, the related issues that sharing the same R&D keywords can be showed in a more systematic way through the issue clustering constructed from the perspective of R&D. Thus, sharing of the R&D result and reusable of the R&D technology can be facilitated. Indirectly, the redundancy of investment on the same R&D can be reduce as the R&D information can be shared between those corresponding issues and reusability of the related R&D can be improved. Therefore, a methodology of constructing an issue clustering from the perspective of common R&D keywords is proposed to satisfy the demands mentioned. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering" title="clustering">clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20network%20analysis" title=" social network analysis"> social network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20mining" title=" text mining"> text mining</a>, <a href="https://publications.waset.org/abstracts/search?q=topic%20analysis" title=" topic analysis"> topic analysis</a> </p> <a href="https://publications.waset.org/abstracts/12451/issue-reorganization-using-the-measure-of-relevance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12451.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">573</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">160</span> Developing a Rational Database Management System (RDBMS) Supporting Product Life Cycle Appications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusri%20Yusof">Yusri Yusof</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Wong%20Keong"> Chen Wong Keong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the implementation details of a Relational Database Management System of a STEP-technology product model repository.

To overcome this, we present a novel approach using modified kernel density estimation (KDE) technique with bilateral filtering to remove noisy points and outliers. First we present a method for estimating optimal bandwidth of multivariate KDE using particle swarm optimization technique which ensures the robust performance of density estimation. Then we use mean-shift algorithm to find the local maxima of the density estimation which gives the centroid of the clusters. Then we compute the distance of a certain point from the centroid. Points belong to outliers then removed by automatic thresholding scheme which yields an accurate and economical point surface.

Through a cross-sectional survey, this study investigates the impact of air quality to the quality of life of patients with the COPD in terms of the scores of the (Chinese) chronic respiratory questionnaire (CCRQ) and the measurements of indoor air quality (IAQ) and Moser’s activities of daily living (ADL). Strong relationships between a number of indoor/outdoor environmental parameters were found and CRQ sub-scores for patients of COPD and thus indoor air pollutants must be monitored for future studies related to QOL for patients with COPD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20obstructive%20pulmonary%20disease%20%28COPD%29" title="chronic obstructive pulmonary disease (COPD)">chronic obstructive pulmonary disease (COPD)</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20air%20pollutants" title=" indoor air pollutants"> indoor air pollutants</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20respiratory%20questionnaire%20%28CRQ%29" title=" chronic respiratory questionnaire (CRQ)"> chronic respiratory questionnaire (CRQ)</a> </p> <a href="https://publications.waset.org/abstracts/39989/environmental-parameters-influence-on-chronic-obstructive-pulmonary-disease-copd-patients-quality-of-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39989.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">424</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">153</span> Investigation of Topic Modeling-Based Semi-Supervised Interpretable Document Classifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dasom%20Kim">Dasom Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Xiu%20Shun%20Wong"> William Xiu Shun Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoonjin%20Hyun"> Yoonjin Hyun</a>, <a href="https://publications.waset.org/abstracts/search?q=Donghoon%20Lee"> Donghoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Minji%20Paek"> Minji Paek</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungho%20Byun"> Sungho Byun</a>, <a href="https://publications.waset.org/abstracts/search?q=Namgyu%20Kim"> Namgyu Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There have been many researches on document classification for classifying voluminous documents automatically. Through document classification, we can assign a specific category to each unlabeled document on the basis of various machine learning algorithms. However, providing labeled documents manually requires considerable time and effort. To overcome the limitations, the semi-supervised learning which uses unlabeled document as well as labeled documents has been invented. However, traditional document classifiers, regardless of supervised or semi-supervised ones, cannot sufficiently explain the reason or the process of the classification. Thus, in this paper, we proposed a methodology to visualize major topics and class components of each document. We believe that our methodology for visualizing topics and classes of each document can enhance the reliability and explanatory power of document classifiers. <p
