Such discussion between the instructor and student or peer-to-peer discussion can be in several different forms. It could be face-to-face discussion, via email and use of online discussion forum. In this study, the effectiveness of using WhatsApp for academic discussion for a first year half-credit Chemistry course was examined. This study was run over two years with two different batches of students. Participation in the study was voluntary and student volunteers were recruited within the first week of the term. The activity in the WhatsApp group was monitored by two instructors teaching the course. At the end of the course, the students participated in an online survey to evaluate their experience of using WhatsApp for academic discussion. There were a total of 26 questions. The survey had a total of 4 sections with regards to the use of WhatsApp for academic discussion: 1) Familiarity with WhatsApp, 2) Effectiveness of using WhatsApp for discussion, 3) Challenges and 4) Overall experience. The main purpose of using an IM platform for academic discussion was to encourage after-class discussion amongst the students. 32% of the participants had used other online platform, such as Piazza and forums in Learning Management System (LMS), for after-class academic discussion with their instructors and peers. This was a low percentage considering that some courses use such online platform as their main forum amongst instructors and students. At the end of our study, over 83% of the participants felt that WhatsApp was a more effective platform compared to other online forum. One interesting finding was the effect of WhatsApp discussion on face-to-face interaction with instructors. 28% of the students agreed that the use of WhatsApp as a discussion forum had encouraged them to approach their instructors during or after class. 51% of students answered neutral. This could be interpreted that the use of WhatsApp had not affected the frequent (or lack of) face-to-face interaction with their instructors. A second survey question, similar but phrased differently from the first, was also asked to evaluate the aspect of face-to-face interaction with instructors. 34% disagreed that the use of WhatsApp had reduced the frequency of face-to-face interaction. This could imply that the frequency remained the same or might have increased. The 38% who agreed to a decrease in face-to-face interaction have either asked the questions in WhatsApp or had their questions answered by a query from another student in the group chat. These outcomes suggested that the use of technology aided and complemented face-to-face interaction between instructors and students. The study also looked at the challenges of using WhatsApp for academic discussion. Some challenges included difficulty in referring back to previous discussion and students finding some discussions irrelevant to them. In conclusion, the use of IM platform for academic discussion was desirable for the students, but it should not be the only channel as face-to-face consultation and online forum for lengthy discussion are still important for after-class learning of students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemistry" title="chemistry">chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=pedogogy" title=" pedogogy"> pedogogy</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20tools" title=" technological tools"> technological tools</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate" title=" undergraduate"> undergraduate</a> </p> <a href="https://publications.waset.org/abstracts/129366/using-smartphone-instant-messaging-im-app-for-academic-discussion-in-an-undergraduate-chemistry-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129366.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">136</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">294</span> Identifying Model to Predict Deterioration of Water Mains Using Robust Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Go%20Bong%20Choi">Go Bong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shin%20Je%20Lee"> Shin Je Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Jin%20Yoo"> Sung Jin Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gibaek%20Lee"> Gibaek Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In South Korea, it is difficult to obtain data for statistical pipe assessment.

ER fluid is a smart material, which cause the suspended particles polarize and connect each other to form chain. The stiffness and damping coefficients of the ER fluid can be changed in 10 micro seconds; therefore, ERF is suitable to become the material embedded in the tunable vibration absorber to become a smart absorber. For the ERF smart material embedded structure, the fuzzy control law depends on the experimental expert database and the proposed self-tuning strategy. The electric field is controlled by a CRIO embedded system to implement the real application. This study investigates the different performances using the Type-1 fuzzy and interval Type-2 fuzzy controllers. The Interval type-2 fuzzy control is used to improve the modeling uncertainties for this ERF embedded shock absorber. The self-tuning vibration controllers using Type-1 and Interval Type-2 fuzzy law are implemented to the shock absorber system. Based on the resulting performance, Internal Type-2 fuzzy is better than the traditional Type-1 fuzzy control for this vibration control system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-rheological%20fluid" title="electro-rheological fluid">electro-rheological fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-active%20vibration%20control" title=" semi-active vibration control"> semi-active vibration control</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber" title=" shock absorber"> shock absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20fuzzy%20control" title=" type 2 fuzzy control "> type 2 fuzzy control </a> </p> <a href="https://publications.waset.org/abstracts/7630/interval-type-2-fuzzy-vibration-control-of-an-erf-embedded-smart-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7630.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">447</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">291</span> 3D Printed Multi-Modal Phantom Using Computed Tomography and 3D X-Ray Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Suk%20Oh">Sung-Suk Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong-Keun%20Kang"> Bong-Keun Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Wook%20Park"> Sang-Wook Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui-Jin%20Joo"> Hui-Jin Joo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ryul%20Choi"> Jong-Ryul Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Jun%20Lee"> Seong-Jun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-Woo%20Sohn"> Jeong-Woo Sohn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The imaging phantom is utilized for the verification, evaluation and tuning of the medical imaging device and system.

Plants, alone or in combination, have been widely used for hair growth promotion since ancient times in Asia. In this study, the efficacy of a traditional Chinese herbal formula, Shen-Ying-Yang-Zhen-Dan (SYYZD) with different kinds of extract solvents, facilitating hair regrowth in testosterone-induced hair loss have been determined. The study was performed by treating with either 95 % ethanol aqueous extracts, 50% ethanol aqueous extracts or deionized water extracts orally in four-week-old male S.D. rats that experienced hair regrowth interruption induced by testosterone treatment. The 50% ethanol aqueous extracts group showed better hair regrowth promotion activities than either 95% ethanol aqueous extracts or deionized water extracts groups in 14 days treatment. In conclusion, our results suggest that 50% ethanol aqueous SYYZD extracts have hair growth promoting potential and may be beneficial as an alternative medicine for androgenetic alopecia treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shen-Ying-Yang-Zhen-Dan" title="Shen-Ying-Yang-Zhen-Dan">Shen-Ying-Yang-Zhen-Dan</a>, <a href="https://publications.waset.org/abstracts/search?q=androgenic%20alopecia" title=" androgenic alopecia"> androgenic alopecia</a>, <a href="https://publications.waset.org/abstracts/search?q=hair%20loss" title=" hair loss"> hair loss</a>, <a href="https://publications.waset.org/abstracts/search?q=hair%20growth%20promotion" title=" hair growth promotion"> hair growth promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=hair%20regrowth%20effect" title=" hair regrowth effect"> hair regrowth effect</a> </p> <a href="https://publications.waset.org/abstracts/16355/hair-regrowth-effect-of-herbal-formula-on-androgenic-alopecia-rat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16355.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">777</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">289</span> A Study on the Establishment of a 4-Joint Based Motion Capture System and Data Acquisition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyeong-Ri%20Ko">Kyeong-Ri Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Bong%20Bae"> Seong Bong Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang%20Sik%20Choi"> Jang Sik Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Bum%20Pan"> Sung Bum Pan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple method for testing the posture imbalance of the human body is to check for differences in the bilateral shoulder and pelvic height of the target.

The aim of this study is to perform a detailed review of this rare disease in a large cohort of patients with TO proven by fiberoptic bronchoscopy from China. Patients and Methods: Retrospective chart review was performed on 41,600 patients who underwent bronchoscopy in the Department of Respiratory Medicine of Changhai Hospital between January 2005 and December 2012. Cases of TO were identified based on characteristic features during bronchoscopic examination. Results: 22 cases of bronchoscopic TO were identified. Among whom one-half were male and the mean age was 47.45 卤10.91 years old. The most frequent symptoms at presentation were chronic cough (n=14) and increased sputum production (n=10). Radiographic abnormalities were observed in 3/18 patients and findings on computed tomography consistent with TO such as beaded intraluminal calcifications and/or increased luminal thickenings were observed in 18/22 patients. Patients were classified into the following categories based on the severity of bronchoscopic findings: Stage I (n=2), Stage II (n=6) and Stage III(n=14). The result that bronchoscopic improvement was observed in 2 patients administered with inhaled corticosteroids suggested that resolution of this disease is possible. Conclusions: TO is a benign disease with slow progression, which could be roughly divided into 3 stages on the basis of the characteristic endoscopic features and histopathologic findings. Chronic inflammation was thought to be more important than the other existing plausible hypotheses in the course of TO. Inhaled corticosteroids might have some impact on patients at Stage I/II. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20obstruction" title="airway obstruction">airway obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchoscopy" title=" bronchoscopy"> bronchoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=etiology" title=" etiology"> etiology</a>, <a href="https://publications.waset.org/abstracts/search?q=Tracheobronchopathia%20osteochondroplastica%20%28TO%29" title=" Tracheobronchopathia osteochondroplastica (TO)"> Tracheobronchopathia osteochondroplastica (TO)</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/17926/a-clinical-study-of-tracheobronchopathia-osteochondroplastica-findings-from-a-large-chinese-cohort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17926.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">464</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">282</span> The Protective Role of Decoy Receptor 3 Analogue on Rat Steatotic Liver against Ischemia-Reperfusion Injury by Blocking M1/Th1 Polarization and Multiple Upstream Pathogenic Cascades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tzu-Hao%20Li">Tzu-Hao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Shie-Liang%20Hsieh"> Shie-Liang Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Chieh%20Lin"> Han-Chieh Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Ying%20Yang"> Ying-Ying Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> TNF superfamily-stimulated pathogenic cascades and macrophage (M1)/kupffer cells (KC) polarization are important in the pathogenesis of ischemia-reperfusion (IR) liver injury in animals with hepatic steatosis (HS). Decoy receptor 3 (DcR3) is a common upstream inhibitor of the above-mentioned pathogenic cascades. The study evaluated whether modulation of these DcR3-related cascades was able to protect steatotic liver from IR injury. Serum and hepatic DcR3 levels were lower in patients and animals with HS. Accordingly, the effects of pharmacologic and genetic DcR3 replacement on the IR-related pathogenic changes were measured. Significantly, DcR3 replacement protected IR-Zucker(HS) rats and IR-DcR3-Tg(HS) mice from IR liver injury. The beneficial effects of DcR3 replacement were accompanied by decreased serum/hepatic TNF, soluble TNF-like cytokine 1A (TL1A), Fas ligand (Fas-L) and LIGHT, T-helper-cell-1 cytokine (INF) levels, neutrophil infiltration, M1 polarization, neutrophil-macrophage/KC-T-cell interaction, hepatocyte apoptosis and improved hepatic microcirculatory failure among animals with IR-injured steatotic livers. Additionally, TL1A, Fas-L, LIGHT and TLR4/NFB signals were found to mediate the DcR3-related protective effects of steatotic livers from IR injury. Using multimodal in vivo and in vitro approaches, we found that DcR3 was a potential agent to protect steatotic livers from IR injury by simultaneous blocking the multiple IR injury-related pathogenic changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Decoy%203%20receptor" title="Decoy 3 receptor">Decoy 3 receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia-reperfusion%20injury" title=" ischemia-reperfusion injury"> ischemia-reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=M1%20polarization" title=" M1 polarization"> M1 polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=TNF%20superfamily" title=" TNF superfamily"> TNF superfamily</a> </p> <a href="https://publications.waset.org/abstracts/77043/the-protective-role-of-decoy-receptor-3-analogue-on-rat-steatotic-liver-against-ischemia-reperfusion-injury-by-blocking-m1th1-polarization-and-multiple-upstream-pathogenic-cascades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77043.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">208</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">281</span> The Empirical Analysis and Comparisons Using TAIEX Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pao-Peng%20Hsu">Pao-Peng Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Hsiu%20Chen"> Ying-Hsiu Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Historical data shows that there were high correlations among TAIEX Futures, Electronic Sector Index Futures, Finance Sector Index Futures and Taiwan Top 50 ETF.

The LFM-FSK method combines FMCW (Frequency Modulation Continuous Wave) signal with FSK (Frequency Shift Keying). This shows an advantage which can suppress the ghost phenomenon without the complicated CFAR (Constant False Alarm Rate) algorithm. Moreover, the parametric sparse algorithm applying the compressive sensing that restores signals efficiently with respect to the incomplete data samples is also integrated, leading to reducing the burden of ADC in the receiver of radars. 24 GHz FMCW signal is applied and tested in the real environment with FSK modulated data for verifying the proposed algorithm along with the compressive sensing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20sensing" title="compressive sensing">compressive sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=LFM-FSK%20radar" title=" LFM-FSK radar"> LFM-FSK radar</a>, <a href="https://publications.waset.org/abstracts/search?q=radar%20signal%20processing" title=" radar signal processing"> radar signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sparse%20algorithm" title=" sparse algorithm"> sparse algorithm</a> </p> <a href="https://publications.waset.org/abstracts/51309/linear-frequency-modulation-frequency-shift-keying-radar-with-compressive-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51309.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">481</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">279</span> Two-Step Patterning of Microfluidic Structures in Paper by Laser Cutting and Wax Printing for Mass Fabrication of Biosensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bong%20Keun%20Kang">Bong Keun Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Suk%20Oh"> Sung Suk Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-Woo%20Sohn"> Jeong-Woo Sohn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ryul%20Choi"> Jong-Ryul Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Ho%20Kim"> Young Ho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we describe two-step micro-pattering by using laser cutting and wax printing. Wax printing is performed only on the bridges for hydrophobic barriers. We prepared 405nm blue-violet laser module and wax pencil module. And, this two modules combine x-y plot. The hollow microstructure formed by laser patterning define the hydrophilic flowing paths. However, bridges are essential to avoid the cutting area being the island. Through the support bridges, microfluidic solution spread out to the unnecessary areas. Chromatography blotting paper was purchased from Whatman. We used 20x20 cm and 46x57 cm of chromatography blotting paper. Axis moving speed of x-y plot was the main parameter of optimization. For aligning between the two patterning, the paper sheet was taped at the bottom. After the two-step patterning, temperature curing step was done at 110-130 掳C. The resolution of the fabrication and the potential of the multiplex detection were investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C2%B5PADs" title="碌PADs">碌PADs</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidic" title=" microfluidic"> microfluidic</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensor" title=" biosensor"> biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=mass-fabrication" title=" mass-fabrication"> mass-fabrication</a> </p> <a href="https://publications.waset.org/abstracts/62844/two-step-patterning-of-microfluidic-structures-in-paper-by-laser-cutting-and-wax-printing-for-mass-fabrication-of-biosensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62844.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">467</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">278</span> Fault Detection of Pipeline in Water Distribution Network System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shin%20Je%20Lee">Shin Je Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Go%20Bong%20Choi"> Go Bong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Cheol%20Seo"> Jeong Cheol Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Gibaek%20Lee"> Gibaek Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water pipe network is installed underground and once equipped; it is difficult to recognize the state of pipes when the leak or burst happens. Accordingly, post management is often delayed after the fault occurs. Therefore, the systematic fault management system of water pipe network is required to prevent the accident and minimize the loss. In this work, we develop online fault detection system of water pipe network using data of pipes such as flow rate or pressure. The transient model describing water flow in pipelines is presented and simulated using Matlab. The fault situations such as the leak or burst can be also simulated and flow rate or pressure data when the fault happens are collected. Faults are detected using statistical methods of fast Fourier transform and discrete wavelet transform, and they are compared to find which method shows the better fault detection performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20detection" title="fault detection">fault detection</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pipeline%20model" title=" water pipeline model"> water pipeline model</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20Fourier%20transform" title=" fast Fourier transform"> fast Fourier transform</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20wavelet%20transform" title=" discrete wavelet transform"> discrete wavelet transform</a> </p> <a href="https://publications.waset.org/abstracts/5007/fault-detection-of-pipeline-in-water-distribution-network-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5007.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">512</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">277</span> Production of Ginseng Berry Wines and Analysis of Their Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Hee%20Choi">Jae Hee Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Il%20Ahn"> Seung Il Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Sae%20Kyul%20Kim"> Sae Kyul Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Wook%20Yang"> Byung Wook Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong%20Sun%20Park"> Bong Sun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwan%20Sup%20Kim"> Hwan Sup Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Tae%20Hahm"> Young Tae Hahm</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The root of Panax ginseng C.

For the selected area, 6 to 12 portable photoionization detector (PID) were placed uniformly in its workplace to measure its total VOCs concentrations (CT-VOCs) for 6 randomly selected workshifts. Simultaneously, one sampling strain was placed beside one of these portable PIDs, and the collected air sample was analyzed for individual concentration (CVOCi) of 5 VOCs (xylene, butanone, toluene, butyl acetate, and dimethylformamide). Predictive models were established by relating the CT-VOCs to CVOCi of each individual compound via simple regression analysis. The established predictive models were employed to predict each CVOCi based on the measured CT-VOC for each the similar working area using the same portable PID. Results show that predictive models obtained from simple linear regression analyses were found with an R2 = 0.83~0.99 indicating that CT-VOCs were adequate for predicting CVOCi. In order to verify the validity of the exposure prediction model, the sampling analysis of the above chemical substances was further carried out and the correlation between the measured value (Cm) and the predicted value (Cp) was analyzed. It was found that there is a good correction between the predicted value and measured value of each measured chemical substance (R2=0.83~0.98). Therefore, the surrogate approach could be assessed the exposure concentration of similar exposed groups using the same chemicals but different formula ratios. However, it is recommended to establish the prediction model between the chemical substances belonging to each coater and the direct-reading PID, which is more representative of reality exposure situation and more accurately to estimate the long-term exposure concentration of operators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exposure%20assessment" title="exposure assessment">exposure assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20prediction%20model" title=" exposure prediction model"> exposure prediction model</a>, <a href="https://publications.waset.org/abstracts/search?q=surrogate%20approach" title=" surrogate approach"> surrogate approach</a>, <a href="https://publications.waset.org/abstracts/search?q=TVOC" title=" TVOC"> TVOC</a> </p> <a href="https://publications.waset.org/abstracts/96267/establishing-a-surrogate-approach-to-assess-the-exposure-concentrations-during-coating-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96267.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">150</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">275</span> The Language of Fliptop among Filipino Youth: A Discourse Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bong%20Borero%20Lumabao">Bong Borero Lumabao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This qualitative research is a study on the lines of Fliptop talks performed by the Fliptop rappers employing Finnegan鈥檚 (2008) discourse analysis.

The aim of the present study is to investigate the effect of SSAO inactivation on the development of atherosclerosis. Methods: Female LDLr knockout (KO) mice were given the Western-type diet for 6 and 9 weeks to induce the formation of early and advanced lesions, and semicarbazide (SCZ, 0.125%) was added into the drinking water to inactivate SSAO in vivo. Results: Despite no impact on plasma total cholesterol levels, abrogation of SSAO by SCZ not only resulted in the enlargement of both early (1.5-fold, p=0.0043) and advanced (1.8-fold, p=0.0013) atherosclerotic lesions, but also led to reduced/increased lesion contents of macrophages/smooth muscle cells (SMCs) (macrophage: ~0.74-fold, p=0.0002(early)/0.0016(advanced); SMC: ~1.55-fold, p=0.0003(early) /0.0001(advanced)), respectively. Moreover, SSAO inactivation inhibited the migration of circulating monocytes into peripheral tissues and reduced the amount of circulating Ly6Chigh monocytes (0.7-fold, p=0.0001), which may account for the reduced macrophage content in lesions. In contrast, the increased number of SMCs in lesions of SCZ-treated mice is attributed to an augmented synthetic vascular SMC phenotype switch as evidenced by the increased proliferation of SMCs and accumulation of collagens in vivo. Conclusion: SSAO inactivation by SCZ promotes the phenotypic switch of SMCs and the development of atherosclerosis. The enzymatic activity of SSAO may thus represent a potential target in the prevention and/or treatment of atherosclerosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atherosclerosis" title="atherosclerosis">atherosclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotype%20switch%20of%20smooth%20muscle%20cells" title=" phenotype switch of smooth muscle cells"> phenotype switch of smooth muscle cells</a>, <a href="https://publications.waset.org/abstracts/search?q=SSAO%2FVAP-1" title=" SSAO/VAP-1"> SSAO/VAP-1</a>, <a href="https://publications.waset.org/abstracts/search?q=semicarbazide" title=" semicarbazide"> semicarbazide</a> </p> <a href="https://publications.waset.org/abstracts/45625/inactivation-of-semicarbazide-sensitive-amine-oxidase-induces-the-phenotypic-switch-of-smooth-muscle-cells-and-aggravates-the-development-of-atherosclerotic-lesions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45625.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">329</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">273</span> Effect of Mineral Admixture on Self-Healing Performance in Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Cheol%20Choi">Young-Cheol Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Won%20Yoo"> Sung-Won Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong%20Chun%20Lee"> Bong Chun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Byoungsun%20Park"> Byoungsun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Hwa%20Jung"> Sang-Hwa Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cracks in concrete commonly provide the passages of ingresses of aggressive and harmful ions into concrete inside and thus reduce the durability of concrete members. In order to solve this problem, self-healing concrete based on mineral admixture has become a major issue. Self-healing materials are those which have the ability of autonomously repairing some damages or small cracks in concrete structures. Concrete has an inherent healing potential, called natural healing, which can take place in ordinary concrete elements but its power is limited and is not predictable. The main mechanism of self-healing in cracked concrete is the continued hydration of unreacted binder and the crystallization of calcium carbonate. Some mineral admixtures have been found to promote the self-healing of cementitious materials. The aim of this study is to investigate the effect of mineral admixture on the self-healing performances of high strength concrete. The potential capability of self-healing of cementitious materials was evaluated using isothermal conduction calorimeter. The self-healing efficiencies were studied by means of water flow tests on cracked concrete specimens. The results show a different healing behaviour depending on presence of the crystalline admixture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mineral%20admixture" title="mineral admixture">mineral admixture</a>, <a href="https://publications.waset.org/abstracts/search?q=self-healing" title=" self-healing"> self-healing</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20flow%20test" title=" water flow test"> water flow test</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/75654/effect-of-mineral-admixture-on-self-healing-performance-in-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75654.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">367</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">272</span> The Right of Taiwanese Individuals with Mental Illnesses to Participate in Medical Decision-Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying-Lun%20Tseng%20Chiu-Ying%20Chen">Ying-Lun Tseng Chiu-Ying Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taiwan's Mental Health Act was amended at the end of 2022; they added regulations regarding refusing compulsory treatment by patients with mental illnesses. In addition, not only by an examination committee, the judge must also assess the patient's need for compulsory treatment. Additionally, the maximum of compulsory hospitalization has been reduced from an unlimited period to a maximum of 60 days. They aim to promote the healthcare autonomy of individuals with mental illnesses in Taiwan and prevent their silenced voice in medical decision-making while they still possess rationality. Furthermore, they plan to use community support and social care networks to replace the current practice of compulsory treatment in Taiwan. This study uses qualitative research methodology, utilizing interview guidelines to inquire about the experiences of Taiwanese who have undergone compulsory hospitalization, compulsory community treatment, and compulsory medical care. The interviews aimed to explore their feelings when they were subjected to compulsory medical intervention, the inside of their illness, their opinions after treatments, and whether alternative medical interventions proposed by them were considered. Additionally, participants also asked about their personal life history and their support networks in their lives. We collected 12 Taiwanese who had experienced compulsory medical interventions and were interviewed 14 times. The findings indicated that participants still possessed rationality during the onset of their illness. However, when they have other treatments to replace compulsory medical, they sometimes diverge from those of the doctors and their families. Finally, doctors prefer their professional judgment and patients' families' option. Therefore, Taiwanese mental health patients' power of decision-making still needs to improve. Because this research uses qualitative research, so difficult to find participants, and the sample size rate was smaller than Taiwan's population, it may have biases in the analysis. So, Taiwan still has significant progress in enhancing the decision-making rights of participants in the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medical%20decision%20making" title="medical decision making">medical decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=compulsory%20treatment" title=" compulsory treatment"> compulsory treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20ethics" title=" medical ethics"> medical ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health%20act" title=" mental health act"> mental health act</a> </p> <a href="https://publications.waset.org/abstracts/168659/the-right-of-taiwanese-individuals-with-mental-illnesses-to-participate-in-medical-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168659.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">80</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">271</span> Grain Refinement of Al-7Si-0.4Mg Alloy by Combination of Al-Ti-B and Mg-Al2Ca Mater Alloys and Their Effects on Tensile Property</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Ok%20Yoon">Young-Ok Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-Yeon%20Lee"> Su-Yeon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Ho%20Ha"> Seong-Ho Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Gil-Yong%20Yeom"> Gil-Yong Yeom</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong-Hwan%20Kim"> Bong-Hwan Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kyu%20Lim"> Hyun-Kyu Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Shae%20K.%20Kim"> Shae K.

Grain refinement has a significant effect on the mechanical properties of castings, mainly since the distribution of secondary phase is changed. As a grain refiner, the Al-Ti-B master alloys containing TiAl3 and TiB2 particles have been widely used in Al foundries. The Mg loss and Mg based inclusion formation by the strong affinity of Mg to oxygen in the melting process of Mg contained alloys have been an issue. This can be significantly improved only by Mg+Al2Ca master alloy as an alloying element instead of pure Mg. Moreover, the eutectic Si modification and grain refinement is simultaneously obtained because Al2Ca behaves as Ca, a typical Si modifier. The present study is focused on the combined effects of Mg+Al2Ca and Al-Ti-B master alloys on the grain refiment of Al-7Si-0.4Mg alloy and their proper ratio for the optimum effect. The aim of this study, therefore, is to investigate the change of the microstructure in Al-7Si-0.4Mg alloy with different ratios of Ti and Al2Ca (detected Ca content) and their effects on the tensile property. The distribution and morphology of the secondary phases by the grain refinement will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-7Si-0.4Mg%20alloy" title="Al-7Si-0.4Mg alloy">Al-7Si-0.4Mg alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=Al2Ca" title=" Al2Ca"> Al2Ca</a>, <a href="https://publications.waset.org/abstracts/search?q=Al-Ti-B%20alloy" title=" Al-Ti-B alloy"> Al-Ti-B alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20refinement" title=" grain refinement"> grain refinement</a> </p> <a href="https://publications.waset.org/abstracts/49096/grain-refinement-of-al-7si-04mg-alloy-by-combination-of-al-ti-b-and-mg-al2ca-mater-alloys-and-their-effects-on-tensile-property" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49096.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">435</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">270</span> Numerical Studies on the Performance of the Finned-Tube Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Praveen%20Kumar">S.

The design of finned-tube heat exchangers requires the selection of over a dozen design parameters by the designer such as tube pitch, tube diameter, tube thickness, etc. Finned-tube heat exchangers are common devices; however, their performance characteristics are complicated. In this paper, numerical studies have been carried out to analyze the performances of finned tube heat exchanger (without fins considered for experimental purpose) by predicting the characteristics of temperature difference and pressure drop. In this study, a design considering 5 design variables, maximizing the temperature difference and minimizing the pressure drop was suggested by applying DOE. In this process, L18 orthogonal array was adopted. Parametric analytical studies have been carried out using Analysis of Variance (ANOVA) to determine the relative importance of each variable with respect to the temperature difference and the pressure drop. Following the results, the final design was suggested by predicting the optimum design therefore confirming the optimized condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title="heat exchanger">heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20analysis" title=" fluid analysis"> fluid analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20variance" title=" analysis of variance"> analysis of variance</a> </p> <a href="https://publications.waset.org/abstracts/4352/numerical-studies-on-the-performance-of-the-finned-tube-heat-exchanger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4352.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">446</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">269</span> Discussion on Microstructural Changes Caused by Deposition Temperature of LZO Doped Mg Piezoelectric Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Ying%20Li">Cheng-Ying Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheng-Yuan%20Chu"> Sheng-Yuan Chu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article deposited LZO-doped Mg piezoelectric thin films via RF sputtering and observed microstructure and electrical characteristics by varying the deposition temperature. The XRD analysis results indicate that LZO-doped Mg exhibits excellent (002) orientation, and there is no presence of ZnO(100), Influenced by the temperature's effect on the lattice constant, the (002) peak intensity increases with rising temperature. Finally, we conducted deformation intensity analysis on the films, revealing an over fourfold increase in deformation at a processing temperature of 500掳C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RF%20sputtering" title="RF sputtering">RF sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectricity" title=" piezoelectricity"> piezoelectricity</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a>, <a href="https://publications.waset.org/abstracts/search?q=Mg" title=" Mg"> Mg</a> </p> <a href="https://publications.waset.org/abstracts/186346/discussion-on-microstructural-changes-caused-by-deposition-temperature-of-lzo-doped-mg-piezoelectric-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186346.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">41</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">268</span> Mooring Analysis of Duct-Type Tidal Current Power System in Shallow Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chul%20H.%20Jo">Chul H.

Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exhaustion of oil and the environmental pollution from the use of fossil fuel are increasing. Tidal current power (TCP) has been proposed as an alternative energy source because of its predictability and reliability. By applying a duct and single point mooring (SPM) system, a TCP device can amplify the generating power and keep its position properly. Because the generating power is proportional to cube of the current stream velocity, amplifying the current speed by applying a duct to a TCP system is an effective way to improve the efficiency of the power device. An SPM system can be applied at any water depth and is highly cost effective. Simple installation and maintenance procedures are also merits of an SPM system. In this study, we designed an SPM system for a duct-type TCP device for use in shallow water. Motions of the duct are investigated to obtain the response amplitude operator (RAO) as the magnitude of the transfer function. Parameters affecting the stability of the SPM system such as the fairlead departure angle, current velocity, and the number of clamp weights are analyzed and/or optimized. Wadam and OrcaFlex commercial software is used to design the mooring line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mooring%20design" title="mooring design">mooring design</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20analysis" title=" parametric analysis"> parametric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=RAO%20%28Response%20Amplitude%20Operator%29" title=" RAO (Response Amplitude Operator)"> RAO (Response Amplitude Operator)</a>, <a href="https://publications.waset.org/abstracts/search?q=SPM%20%28Single%20Point%20Mooring%29" title=" SPM (Single Point Mooring)"> SPM (Single Point Mooring)</a> </p> <a href="https://publications.waset.org/abstracts/42998/mooring-analysis-of-duct-type-tidal-current-power-system-in-shallow-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42998.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">289</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">267</span> Catalytic Cracking of Butene to Propylene over Modified HZSM-5 Zeolites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianwen%20Li">Jianwen Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiwen%20Sun"> Qiwen Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Catalytic cracking of butene to propylene was carried out in a continuous-flow fixed-bed reactor over HZSM-5 catalysts modified by nickel and phosphorus. The structure and acidity of catalysts were measured by N2 adsorption, NH3-TPD and XPS. The results revealed that surface area and strong acid sites both decreased with increasing phosphorus loadings. The increment of phosphorus loadings reduced the butene conversion but enhanced the propylene selectivity and catalyst stability. <p class="card-text"><strong>Keywords:</strong> <a
