This study examined the relationships between communicative competence, language proficiency, and employability using descriptive analysis and inferential statistics. Next, Pearson’s Correlation determines the correlation between communication competence, language proficiency, and employability skills of Malaysian Polytechnic ESL engineering students. The total number of participants was 81 final-year engineering students. The findings revealed high positive correlations between the communicative competence -'I can talk with a friend in English.' and employability skill (r = 0.854, p = .031), also, language proficiency -'I can understand the English songs I listen to' and employability skill (r = 0.887, p = .038). The result is consistent with the theories. The result revealed that for the 81 students, communication competence and language proficiency, and employability skills are firmly and significantly correlated. Thus, it concluded that both communicative competence and language proficiency equally essential to ensure a higher employability rate among Malaysian polytechnic ESL engineering students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communicative%20competence" title="communicative competence">communicative competence</a>, <a href="https://publications.waset.org/abstracts/search?q=employability" title=" employability"> employability</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20proficiency" title=" language proficiency"> language proficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysian%20polytechnic" title=" Malaysian polytechnic"> Malaysian polytechnic</a> </p> <a href="https://publications.waset.org/abstracts/138854/communication-competence-or-language-proficiency-for-employability-an-investigation-on-malaysian-polytechnics-esl-engineering-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138854.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">160</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">177</span> The Planning Strategies of Public Sports Facilities Based on the Field Investigation: Case Study of Songyuan, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Hua%20Li">Li Hua Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ling%20Ling%20Li"> Ling Ling Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the National Fitness Program being established as a national strategy by the Chinese government, Chinese old planning strategies of sports facilities which are based on the purpose for hosting high-level sports events have been failed to meet the rapid growth of Chinese residents’ healthy needs. As the most important carrier for promoting the health of citizens in China, public sports facilities may have further conflicts when they are planned without considering the characteristics of the city itself and the fitness needs of the urban residents. With the planning practice in Songyuan in northeastern China, this paper explores the key planning strategies of public sports facilities through the field investigation to obtain the current situation of public sports facilities in Songyuan and the questionnaire to get the date of Songyuan residents’ fitness characteristics and needs. Findings from this investigation suggest that the planning of public sports facilities in Songyuan should first increase the quantities of public sports facilities at the community level, which could match the fitness population and meet the fitness needs in Songyuan. Secondly, the planning should combine with other available resources, such as urban parks, squares and other places where Songyuan residents often choose to do physical activities to enhance the vitality of public sports facilities. Finally, the planning should also link the urban transportation system in Songyuan to improve the accessibility and efficiency of public sports facilities. All these planning strategies could provide essential information for updating the urban and regional design of Songyuan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=field%20investigation" title="field investigation">field investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20needs" title=" healthy needs"> healthy needs</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sports%20facilities" title=" public sports facilities"> public sports facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=planning%20strategies" title=" planning strategies"> planning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a> </p> <a href="https://publications.waset.org/abstracts/80508/the-planning-strategies-of-public-sports-facilities-based-on-the-field-investigation-case-study-of-songyuan-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80508.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">237</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">176</span> Measuring Banking Systemic Risk Conditional Value-At-Risk and Conditional Coherent Expected Shortfall in Taiwan Using Vector Quantile GARCH Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ender%20Su">Ender Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai%20Wen%20Wong"> Kai Wen Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=I-Ling%20Ju"> I-Ling Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Ya-Ling%20Wang"> Ya-Ling Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the systemic risk change of Taiwan’s banking sector is analyzed during the financial crisis. The risk expose of each financial institutions to the whole Taiwan banking systemic risk or vice versa under financial distress are measured by conditional Value-at-Risk (CoVaR) and conditional coherent expected shortfall (CoES). The CoVaR and CoES are estimated by using vector quantile autoregression (MVMQ-CaViaR) with the daily stock returns of each banks included domestic and foreign banks in Taiwan. The daily in-sample data covered the period from 05/20/2002 to 07/31/2007 and the out-of-sample period until 12/31/2013 spanning the 2008 U.S. subprime crisis, 2010 Greek debt crisis, and post risk duration. All banks in Taiwan are categorised into several groups according to their size of market capital, leverage and domestic/foreign to find out what the extent of changes of the systemic risk as the risk changes between the individuals in the bank groups and vice versa. The final results can provide a guidance to financial supervisory commission of Taiwan to gauge the downside risk in the system of financial institutions and determine the minimum capital requirement hold by financial institutions due to the sensibility changes in CoVaR and CoES of each banks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bank%20financial%20distress" title="bank financial distress">bank financial distress</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20quantile%20autoregression" title=" vector quantile autoregression"> vector quantile autoregression</a>, <a href="https://publications.waset.org/abstracts/search?q=CoVaR" title=" CoVaR"> CoVaR</a>, <a href="https://publications.waset.org/abstracts/search?q=CoES" title=" CoES"> CoES</a> </p> <a href="https://publications.waset.org/abstracts/53814/measuring-banking-systemic-risk-conditional-value-at-risk-and-conditional-coherent-expected-shortfall-in-taiwan-using-vector-quantile-garch-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53814.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">386</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">175</span> Development and Characterization of Controlled Release Photo Cross-Linked Implants for Ocular Delivery of Triamcinolone Acetonide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravi%20Sheshala">Ravi Sheshala</a>, <a href="https://publications.waset.org/abstracts/search?q=Annie%20Lee"> Annie Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ai%20Lin%20Ong"> Ai Lin Ong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ling%20Ling%20Cheu"> Ling Ling Cheu</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiagarajan%20Madheswaran"> Thiagarajan Madheswaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Thankur%20R.%20R.%20Singh"> Thankur R.

The photo cross-linked implants were prepared using film casting technique by mixing TA (2.5%) polyethylene glycol diacrylate (PEGDA 700), pore formers (mannitol, maltose, and gelatin) and the photoinitiator (Irgacure 2959). The resulting mixture was injected into moulds using 21 G and subjected to photocrosslinking at 365 nm. Scanning electron microscopy results demonstrated that more pores were formed in the films with the increase in the concentration of pore formers from 2%-10%. The maximum force required to break the films containing 2-10% of pore formers were determined in both dry and wet conditions using texture analyzer and found that films in a dry condition required a higher force to break compared to wet condition and blank films. In vitro drug release from photo cross-linked films were determined by incubating samples in 50 ml PBS pH 7.4 at 37 C and the samples were analyzed for drug release by HPLC. The films demonstrated a biphasic release profile i.e. an initial burst release (<20%) on the first day followed by a constant and continuous drug release in a controlled manner for 42 days. The drug release from all formulations followed the first-order release pattern and the combination of diffusion and erosion release mechanism. In conclusion, the developed formulations were able to provide controlled drug delivery to treat the chronic ocular diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=controlled%20release" title="controlled release">controlled release</a>, <a href="https://publications.waset.org/abstracts/search?q=ophthalmic" title=" ophthalmic"> ophthalmic</a>, <a href="https://publications.waset.org/abstracts/search?q=PEGDA" title=" PEGDA"> PEGDA</a>, <a href="https://publications.waset.org/abstracts/search?q=photocrosslinking" title=" photocrosslinking"> photocrosslinking</a>, <a href="https://publications.waset.org/abstracts/search?q=pore%20formers" title=" pore formers"> pore formers</a> </p> <a href="https://publications.waset.org/abstracts/51380/development-and-characterization-of-controlled-release-photo-cross-linked-implants-for-ocular-delivery-of-triamcinolone-acetonide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51380.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">404</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> Synergistic Cytotoxicity of Cisplatin and Taxol in Overcoming Taxol Resistance through the Inhibition of LDHA in Oral Squamous Cell Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lin%20Feng">Lin Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Ling-Ling%20E."> Ling-Ling E.</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong-Chen%20Liu"> Hong-Chen Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of chemoresistance in patients represents a major challenge in cancer treatment. Lactate dehydrogenase‑A (LDHA) is one of the principle isoforms of LDH that is expressed in breast tissue, controlling the conversion of pyruvate to lactate and also playing a significant role in the metabolism of glucose. The aim of this study was to identify whether LDHA was involved in oral cancer cell resistance to Taxol and whether the downregulation of LDHA, as a result of cisplatin treatment, may overcome Taxol resistance in human oral squamous cells. The OECM‑1 oral epidermal carcinoma cell line was used, which has been widely used as a model of oral cancer in previous studies. The role of LDHA in Taxol and cisplatin resistance was investigated and the synergistic cytotoxicity of cisplatin and/or Taxol in oral squamous cells was analyzed. Cell viability was analyzed by MTT assay, LDHA expression was analyzed by western blot analysis and siRNA transfection was performed to knock down LDHA expression. The present study results showed that decreased levels of LDHA were responsible for the resistance of oral cancer cells to cisplatin (CDDP). CDDP treatments downregulated LDHA expression and lower levels of LDHA were detected in the CDDP‑resistant oral cancer cells compared with the CDDP‑sensitive cells. By contrast, the Taxol‑resistant cancer cells showed elevated LDHA expression levels. In addition, small interfering RNA‑knockdown of LDHA sensitized the cells to Taxol but desensitized them to CDDP treatment while exogenous expression of LDHA sensitized the cells to CDDP, but desensitized them to Taxol. The present study also revealed the synergistic cytotoxicity of CDDP and Taxol for killing oral cancer cells through the inhibition of LDHA. This study highlights LDHA as a novel therapeutic target for overcoming Taxol resistance in oral cancer patients using the combined treatments of Taxol and CDDP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cisplatin" title="cisplatin">cisplatin</a>, <a href="https://publications.waset.org/abstracts/search?q=Taxol" title=" Taxol"> Taxol</a>, <a href="https://publications.waset.org/abstracts/search?q=carcinoma" title=" carcinoma"> carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20squamous%20cells" title=" oral squamous cells"> oral squamous cells</a> </p> <a href="https://publications.waset.org/abstracts/27921/synergistic-cytotoxicity-of-cisplatin-and-taxol-in-overcoming-taxol-resistance-through-the-inhibition-of-ldha-in-oral-squamous-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27921.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">418</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">173</span> Can Career Advancement and Job Security Act as Collaterals for Commitment?

The long-term goal of this study is to lengthen the professional life of operating room nurses by attenuating the work stress and enhancing their contentment in work. Method: This was a cross-sectional, descriptive study performed in a metropolitan teaching hospital in the southern Taiwan between May 2017 to July 2017. A structured self-administered questionnaire, modified from the Occupational Stress Indicator-2 (OSI-2) and Maslach Burnout Inventory (MBI) manual was collected from the operating room nurses. Chi-square test was used to analyze the categorical data and Pearson correlation was used to analyze the association between two numerical datasets (SPSS version 20.0). Results: The response rate was 80% (80/100) and a total of 73 (73%) completed forms were eventually proceeded for analysis. The average scores for work stress and job satisfaction of the operating room nurses were 145.96±32.91 and 47.38±6.07, respectively. The correlation coefficients of work stress versus job satisfaction and organizational identity were (r=-0.338, p=0.003 and r=-0.354, p=0.002), respectively. There were more nurses who took rotating shift quitted works from the operating room than those who took only dayshift (2＝5.176, p<0.05). Nurses who reported of having lower job satisfaction were associated with significantly higher turnover intention (t=3.714, p< 0.01). Following multivariate regression analysis, rotating shift and low job satisfaction were identified as the two independent predictors of intention to quit from working in the operating room. Conclusion: Our study clearly demonstrates that increased work stress significantly attenuates job satisfaction and organizational identity. Rotating shift is associated with higher work stress, lower job satisfaction, and higher turnover intention, which is consistent with the previous surveys carried out in the department of medical technology. Therefore, improvement of working quality in the operating rooms is essential to increase the retain intention of the well-trained nursing staffs. Further investigation into types of work shifts and other strategies of attenuating stress in workplace is currently undertaken in order to improve the job satisfaction and to decrease turnover intention in the operating room. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rotating%20shift" title="rotating shift">rotating shift</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20stress" title=" work stress"> work stress</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20satisfaction" title=" job satisfaction"> job satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=turnover%20intention" title=" turnover intention"> turnover intention</a> </p> <a href="https://publications.waset.org/abstracts/85554/the-association-of-excessive-work-stress-with-job-satisfaction-and-turnover-intention-in-operating-room-nurses-a-cross-sectional-study-in-a-metropolitan-teaching-hospital-in-southern-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85554.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">197</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">170</span> New High Order Group Iterative Schemes in the Solution of Poisson Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sam%20Teek%20Ling">Sam Teek Ling</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhashidah%20Hj.%20Mohd.%20Ali"> Norhashidah Hj.

This study investigated the influence of work stress on the burnout and turnover intention of nurse anesthetists in a regional general hospital in Southern Taiwan. Methods: This was a descriptive correlational study carried out in 66 full-time nurse anesthetists. Data was collected from March 2017 to June 2017 by in-person interview, and a self-administered structured questionnaire was completed by the interviewee. Outcome measurements included the Practice Environment Scale of the Nursing Work Index (PES-NWI), Maslach Burnout Inventory (MBI) and nursing staff turnover intention. Numerical data were analyzed by descriptive statistics, independent t test, or one-way ANOVA. Categorical data were compared using the chi-square test (x²). Datasets were computed with Pearson product-moment correlation and linear regression. Data were analyzed by using SPSS 20.0 software. Results: The average score for job burnout was 68.7916.67 (out of 100). The three major components of burnout, including emotional depletion (mean score of 26.32), depersonalization (mean score of 13.65), and personal(mean score of 24.48). These average scores suggested that these nurse anesthetists were at high risk of burnout and inversely correlated with turnover intention (t = -4.048, P < 0.05). Using linear regression model, emotional exhaustion and depersonalization were the two independent factors that predicted turnover intention in the nurse anesthetists (19.1% in total variance). Conclusion/Implications for Practice: The study identifies that the high risk of job burnout in the nurse anesthetists is not simply derived from physical overload, but most likely resulted from the additional emotional and psychological stress. The occurrence of job burnout may affect the quality of nursing work, and also influence family harmony, in turn, may increase the turnover rate. Multimodal approach is warranted to reduce work stress and job burnout in nurse anesthetists to enhance their willingness to contribute in anesthesia care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anesthesia%20nurses" title="anesthesia nurses">anesthesia nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=burnout" title=" burnout"> burnout</a>, <a href="https://publications.waset.org/abstracts/search?q=job" title=" job"> job</a>, <a href="https://publications.waset.org/abstracts/search?q=turnover%20intention" title=" turnover intention"> turnover intention</a> </p> <a href="https://publications.waset.org/abstracts/85613/the-investigation-of-work-stress-and-burnout-in-nurse-anesthetists-a-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85613.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">296</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> Effects of Nanoencapsulated Echinacea purpurea Ethanol Extract on the Male Reproductive Function in Streptozotocin-Induced Diabetic Rats </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jia-Ling%20Ho">Jia-Ling Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiu-Ru%20Zhang"> Xiu-Ru Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zwe-Ling%20Kong"> Zwe-Ling Kong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diabetes mellitus (DM) is a major health problem that affects patients’ life quality throughout the world due to its many complications. It characterized by chronic hyperglycemia with oxidative stress, which impaired male reproductive function. Fibroblast growth factor 21 (FGF21) is a metabolic regulator that is required for normal spermatogenesis and protects against diabetes-induced germ cell apoptosis. Echinacea purpurea ethanol extract (EE), which contain phenolic acid and isobutylamide, had been proven to have antidiabetic property. Silica-chitosan nanoparticles (Nano-CS) has drug delivery and controlled release properties. This study aims to investigate whether silica-chitosan nanoparticles encapsulated EE (Nano-EE) had more ameliorating male infertility by analyzing the effect of testicular FGF21. The Nano-EE was characterized before used to treatment the diabetic rat model. Male Sprague-Dawley (SD) rats were obtained and divided into seven groups. A group was no induced Streptozotocin (STZ), marked as normal group. Diabetic rats were induced into diabetes by STZ (33 mg/kg). A diabetic group was no treatment with sample (diabetic control group), and other groups were treatment by Nano-CS (465 mg/kg), Nano-EE (93, 279, 465 mg/kg), and metformin (Met) (200 mg/kg) used as reference drug for 7 weeks. Our results indicated that the average nanoparticle size and zeta potential of Nano-EE were 2630 nm and -21.3 mV, respectively. The encapsulation ratio of Nano-EE was about 70%. It also confirmed the antioxidative activity was unchanged by comparing the DPPH and ABTS scavenging of Nano-EE and EE. In vivo test, Nano-EE can improve the STZ induced hyperglycemia, insulin resistance, and plasma FGF21 levels. Nano-EE has increased sperm motility, mitochondria membrane potential (MMP), plasma testosterone level, and reduction of abnormal sperm, nitric oxide (NO), superoxide production as well as reactive oxygen species (ROS). In addition, in plasma antioxidant enzymes glutathione peroxidase (GPx) and superoxide dismutase (SOD) was increased whereas pro-inflammatory cytokines TNF-α, and IL-1β were decreased. Further, in testis, protein content of FGF21, PGC-1α, and SIRT1 were improved. Nano-EE might improve diabetes-induced down-regulation of testicular FGF21 and SIRT1/PGC-1α signaling hence maintain spermatogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=Echinacea%20purpurea" title=" Echinacea purpurea"> Echinacea purpurea</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20dysfunction" title=" reproductive dysfunction"> reproductive dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=silica-chitosan%20nanoparticles" title=" silica-chitosan nanoparticles"> silica-chitosan nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/92184/effects-of-nanoencapsulated-echinacea-purpurea-ethanol-extract-on-the-male-reproductive-function-in-streptozotocin-induced-diabetic-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92184.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">192</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> An Application-Based Indoor Environmental Quality (IEQ) Calculator for Residential Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwok%20W.%20Mui">Kwok W.

Elevated levels of nitrite also found in edible bird’s nests (EBNs). Consumption of NO2- ion at levels above the health-based risk may cause cancer in humans. Spectrophotometric Griess test is the simplest established standard method for NO2- ion detection, however, it requires careful control of pH of each reaction step and susceptible to strong oxidants and dyeing interferences. Other traditional methods rely on the use of laboratory-scale instruments such as GC-MS, HPLC and ion chromatography, which cannot give real-time response. Therefore, it is of signiﬁcant need for devices capable of measuring nitrite concentration in-situ, rapidly and without reagents, sample pretreatment or extraction step. Herein, we constructed a microspheres-based microbial optode for visual quantitation of NO2- ion. Raoutella planticola, the bacterium expressing NAD(P)H nitrite reductase (NiR) enzyme has been successfully extracted by microbial technique from EBN collected from local birdhouse. The whole cells and the lipophilic Nile Blue chromoionophore were physically absorbed on the photocurable poly(n-butyl acrylate-N-acryloxysuccinimide) [poly (nBA-NAS)] microspheres, whilst the reduced coenzyme NAD(P)H was covalently immobilized on the succinimide-functionalized acrylic microspheres to produce a reagentless biosensing system. Upon the NiR enzyme catalyzes the oxidation of NAD(P)H to NAD(P)+, NO2- ion is reduced to ammonium hydroxide, and that a colour change from blue to pink of the immobilized Nile Blue chromoionophore is perceived as a result of deprotonation reaction increasing the local pH in the microspheres membrane. The microspheres-based optosensor was optimized with a reflectance spectrophotometer at 639 nm and pH 8. The resulting microbial bio-optode membrane could quantify NO2- ion at 0.1 ppm and had a linear response up to 400 ppm. Due to the large surface area to mass ratio of the acrylic microspheres, it allows efficient solid state diffusional mass transfer of the substrate to the bio-recognition phase, and achieve the steady state response as fast as 5 min. The proposed optical microbial biosensor requires no sample pre-treatment step and possesses high stability as the whole cell biocatalyst provides protection to the enzymes from interfering substances, hence it is suitable for measurements in contaminated samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acrylic%20microspheres" title="acrylic microspheres">acrylic microspheres</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20bio-optode" title=" microbial bio-optode"> microbial bio-optode</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrite%20ion" title=" nitrite ion"> nitrite ion</a>, <a href="https://publications.waset.org/abstracts/search?q=reflectometric" title=" reflectometric"> reflectometric</a> </p> <a href="https://publications.waset.org/abstracts/23850/acrylic-microspheres-based-microbial-bio-optode-for-nitrite-ion-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23850.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">448</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">165</span> Continuous Catalytic Hydrogenation and Purification for Synthesis Non-Phthalate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Ling%20Li">Chia-Ling Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The scope of this article includes the production of 10,000 metric tons of non-phthalate per annum.

Afterwards, the data set is divided into two parts, the training data set and the testing data set. By the training data set the best structure of GEP and ANN are selected and to evaluate the power of the mentioned methods the testing data set is used. The result obtained shows that the accuracy of GEP is more than ANN. Moreover, unlike ANN, a mathematical equation is presented by GEP for the supplier selection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supplier%20selection" title="supplier selection">supplier selection</a>, <a href="https://publications.waset.org/abstracts/search?q=automotive%20supply%20chains" title=" automotive supply chains"> automotive supply chains</a>, <a href="https://publications.waset.org/abstracts/search?q=ANN" title=" ANN"> ANN</a>, <a href="https://publications.waset.org/abstracts/search?q=GEP" title=" GEP"> GEP</a> </p> <a href="https://publications.waset.org/abstracts/28503/artificial-intelligence-based-comparative-analysis-for-supplier-selection-in-multi-echelon-automotive-supply-chains-via-gep-and-ann-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28503.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">631</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> Optimal Resource Configuration and Allocation Planning Problem for Bottleneck Machines and Auxiliary Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yin-Yann%20Chen">Yin-Yann Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Ling%20Chen"> Tzu-Ling Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the case of an actual Taiwanese semiconductor assembly and testing manufacturer. Three major bottleneck manufacturing processes, namely, die bond, wire bond, and molding, are analyzed to determine how to use finite resources to achieve the optimal capacity allocation. A medium-term capacity allocation planning model is developed by considering the optimal total profit to satisfy the promised volume demanded by customers and to obtain the best migration decision among production lines for machines and tools. Finally, sensitivity analysis based on the actual case is provided to explore the effect of various parameter levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacity%20planning" title="capacity planning">capacity planning</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20allocation" title=" capacity allocation"> capacity allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20migration" title=" machine migration"> machine migration</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20configuration" title=" resource configuration"> resource configuration</a> </p> <a href="https://publications.waset.org/abstracts/49417/optimal-resource-configuration-and-allocation-planning-problem-for-bottleneck-machines-and-auxiliary-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49417.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">461</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">159</span> Developing a Model for Information Giving Behavior in Virtual Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pui-Lai%20To">Pui-Lai To</a>, <a href="https://publications.waset.org/abstracts/search?q=Chechen%20Liao"> Chechen Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Ling%20Lin"> Tzu-Ling Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Virtual communities have created a range of new social spaces in which to meet and interact with one another. Both as a stand-alone model or as a supplement to sustain competitive advantage for normal business models, building virtual communities has been hailed as one of the major strategic innovations of the new economy. However for a virtual community to evolve, the biggest challenge is how to make members actively give information or provide advice. Even in busy virtual communities, usually, only a small fraction of members post information actively. In order to investigate the determinants of information giving willingness of those contributors who usually actively provide their opinions, we proposed a model to understand the reasons for contribution in communities. The study will definitely serve as a basis for the future growth of information giving in virtual communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20giving" title="information giving">information giving</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20identity" title=" social identity"> social identity</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20community" title=" virtual community"> virtual community</a> </p> <a href="https://publications.waset.org/abstracts/50884/developing-a-model-for-information-giving-behavior-in-virtual-communities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50884.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">322</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">158</span> Search for New Design Elements in Time-Honoured Shops in Tainan — On Curriculum Practice about Culture Creative Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ya-Ling%20Huang">Ya-Ling Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Chun%20Tsai"> Ming-Chun Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Fan%20Hsu"> Fan Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai-Ru%20Hsieh"> Kai-Ru Hsieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper mainly discusses the research and practice process of a laboratory curriculum by leading students to perform field investigation into time-honoured shops that have existed for more than 50 years in the downtown area of Tainan, Taiwan, and then search again for design elements and completing the design.

Methods: Autologous DPSCs were isolated from rabbit dental pulp tissue and expanded ex vivo to enrich DPSCs numbers, and then their attachment and differentiation capability were evaluated when cultured on the culture plate or nHAC/PLA. The alveolar bone defects were treated with nHAC/PLA, nHAC/PLA+rhBMP-2, nHAC/PLA+DPSCs, nHAC/PLA+DPSCs+rhBMP-2, and autogenous bone (AB) obtained from iliac bone or were left untreated as a control. X-ray and a polychrome sequential fluorescent labeling were performed post-operatively and the animals were sacrificed 12 weeks after operation for histological observation and histomorphometric analysis. Results: Our results showed that DPSCs expressed STRO-1 and vementin, and favoured osteogenesis and adipogenesis in conditioned media. DPSCs attached and spread well, and retained their osteogenic phenotypes on nHAC/PLA. The rhBMP-2 could significantly increase protein content, alkaline phosphatase (ALP) activity/protein, osteocalcin (OCN) content, and mineral formation of DPSCs cultured on nHAC/PLA. The X-ray graph, the fluorescent, histological observation and histomorphometric analysis showed that the nHAC/PLA+DPSCs+rhBMP-2 tissue-engineered bone complex had an earlier mineralization and more bone formation inside the scaffold than nHAC/PLA, nHAC/PLA+rhBMP-2 and nHAC/PLA+DPSCs, or even autologous bone. Implanted DPSCs contribution to new bone were detected through transfected eGFP genes. Conclutions: Our findings indicated that stem cells existed in adult rabbit dental pulp tissue. The rhBMP-2 promoted osteogenic capability of DPSCs as a potential cell source for periodontal bone regeneration. The nHAC/PLA could serve as a good scaffold for autologous DPSCs seeding, proliferation and differentiation. The tissue-engineered bone complex with nHAC/PLA, rhBMP-2, and autologous DPSCs might be a better alternative to autologous bone for the clinical reconstruction of periodontal bone defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano-hydroxyapatite%2Fcollagen%2Fpoly%20%28L-lactide%29" title="nano-hydroxyapatite/collagen/poly (L-lactide)">nano-hydroxyapatite/collagen/poly (L-lactide)</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20pulp%20stem%20cell" title=" dental pulp stem cell"> dental pulp stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=recombinant%20human%20bone%20morphogenetic%20protein" title=" recombinant human bone morphogenetic protein"> recombinant human bone morphogenetic protein</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title=" bone tissue engineering"> bone tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=alveolar%20bone" title=" alveolar bone"> alveolar bone</a> </p> <a href="https://publications.waset.org/abstracts/21179/reconstruction-of-alveolar-bone-defects-using-bone-morphogenetic-protein-2-mediated-rabbit-dental-pulp-stem-cells-seeded-on-nano-hydroxyapatitecollagenpolyl-lactide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21179.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">401</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">156</span> Several Spectrally Non-Arbitrary Ray Patterns of Order 4</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ling%20Zhang">Ling Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Liu"> Feng Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A matrix is called a ray pattern matrix if its entries are either 0 or a ray in complex plane which originates from 0.

Considering the representative unit cell of graphene under various loading conditions, the deformations of carbon bonds and the variations of the interlayer distance could be realized numerically under the geometry constraints and minimum energy assumption. In elastic region, it was found that graphene was in-plane isotropic. Meanwhile, the in-plane deformation of the representative unit cell is not uniform along armchair direction due to the discrete and non-uniform distributions of the atoms. The fracture of graphene could be predicted using fracture criteria based on the critical bond length, over which the bond would break. It was noticed that the fracture behavior were directional dependent, which was consistent with molecular dynamics simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20minimization" title="energy minimization">energy minimization</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20mechanics" title=" molecular mechanics"> molecular mechanics</a> </p> <a href="https://publications.waset.org/abstracts/25956/the-study-on-mechanical-properties-of-graphene-using-molecular-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25956.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">402</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">154</span> The Study of Participant Motivation, Social Support, and Training Satisfaction of Collegiate Teakwondo Athlete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen-Goang%20Yang">Wen-Goang Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Wei%20Liu"> Li-Wei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Peli-Ling%20Liu"> Peli-Ling Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to explore relations among athletic participant motivation, social support, and training satisfaction.

Since many of the greatest threats to human health are spread by direct person-to-person contact, understanding the spread of respiratory pathogens and patterns of human interactions are public health priorities. This study used social contact diaries to compare the number of contacts per day per participant across different flu/non-flu seasons and weekend/weekday. We also present contact properties such as sex, age, masking, setting, frequency, duration, and contact types among school-age children (grades 7–8). The sample size with pair-wise comparisons for the seasons (flu/non-flu) and stratification by location were 54 and 83, respectively. There was no difference in the number of contacts during the flu and non-flu seasons, with averages of 16.3 (S.D. = 12.9) and 14.6 (S.D. = 9.5) people, respectively. Weekdays were associated with 23% and 28% more contacts than weekend days during the non-flu and flu seasons, respectively (p < 0.001) (Wilcoxon signed-rank test). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20patterns" title="contact patterns">contact patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior" title=" behavior"> behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=influenza" title=" influenza"> influenza</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20mixing" title=" social mixing"> social mixing</a> </p> <a href="https://publications.waset.org/abstracts/42689/social-contact-patterns-among-school-age-children-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42689.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">345</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">150</span> Constructing Orthogonal De Bruijn and Kautz Sequences and Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaw-Ling%20Lin">Yaw-Ling Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A de Bruijn graph of order k is a graph whose vertices representing all length-k sequences with edges joining pairs of vertices whose sequences have maximum possible overlap (length k−1). Every Hamiltonian cycle of this graph defines a distinct, minimum length de Bruijn sequence containing all k-mers exactly once. A Kautz sequence is the minimal generating sequence so as the sequence of minimal length that produces all possible length-k sequences with the restriction that every two consecutive alphabets in the sequences must be different. A collection of de Bruijn/Kautz sequences are orthogonal if any two sequences are of maximally differ in sequence composition; that is, the maximum length of their common substring is k. In this paper, we discuss how such a collection of (maximal) orthogonal de Bruijn/Kautz sequences can be made and use the algorithm to build up a web application service for the synthesized DNA and other related biomolecular sequences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomolecular%20sequence%20synthesis" title="biomolecular sequence synthesis">biomolecular sequence synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=de%20Bruijn%20sequences" title=" de Bruijn sequences"> de Bruijn sequences</a>, <a href="https://publications.waset.org/abstracts/search?q=Eulerian%20cycle" title=" Eulerian cycle"> Eulerian cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamiltonian%20cycle" title=" Hamiltonian cycle"> Hamiltonian cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=Kautz%20sequences" title=" Kautz sequences"> Kautz sequences</a>, <a href="https://publications.waset.org/abstracts/search?q=orthogonal%20sequences" title=" orthogonal sequences"> orthogonal sequences</a> </p> <a href="https://publications.waset.org/abstracts/121912/constructing-orthogonal-de-bruijn-and-kautz-sequences-and-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121912.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">167</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">149</span> Environmental Parameters Influence on Chronic Obstructive Pulmonary Disease (COPD) Patients’ Quality of Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwok%20W.%20Mui">Kwok W.

Investigators are eager to explore the environmental risk factors for COPD such as air pollution and occupational exposure. 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
