class="card-text"><strong>Abstract:</strong></p> This study is to develop a methanol steam reformer with a heat recovery zone, which recovers heat from exhaust gas of a diesel engine, and to investigate waste heat recovery ratio at the required reaction temperature. The operation conditions of the reformer are reaction temperature (200 °C, 250 °C, and 300 °C), steam to carbonate (S/C) ratio (0.9, 1.1, and 1.3), and N2 volume flow rate (40 cm3/min, 70 cm3/min, and 100 cm3/min). Finally, the hydrogen concentration, the CO, CO2, and N2 concentrations are measured and recorded to calculate methanol conversion efficiency, hydrogen flow rate, and assisting combustion gas and impeding combustion gas ratio. The heat source of this reformer comes from electric heater and waste heat of exhaust gas from diesel engines. The objective is to recover waste heat from the engine and to make more uniform temperature distribution within the reformer. It is beneficial for the reformer to enhance the methanol conversion efficiency and hydrogen-rich gas production. Experimental results show that the highest hydrogen flow rate exists at N2 of the volume rate 40 cm3/min and reforming reaction temperature of 300 °C and the value is 19.6 l/min. With the electric heater and heat recovery from exhaust gas, the maximum heat recovery ratio is 13.18 % occurring at water-methanol (S/C) ratio of 1.3 and the reforming reaction temperature of 300 °C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20recovery" title="heat recovery">heat recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen-rich%20production" title=" hydrogen-rich production"> hydrogen-rich production</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20steam%20reformer" title=" methanol steam reformer"> methanol steam reformer</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20conversion%20efficiency" title=" methanol conversion efficiency"> methanol conversion efficiency</a> </p> <a href="https://publications.waset.org/abstracts/14202/methanol-steam-reforming-with-heat-recovery-for-hydrogen-rich-gas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14202.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">466</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Brainbow Image Segmentation Using Bayesian Sequential Partitioning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yayun%20Hsu">Yayun Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Horng-Shing%20Lu"> Henry Horng-Shing Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a data-driven, biology-inspired neural segmentation method of 3D drosophila Brainbow images. We use Bayesian Sequential Partitioning algorithm for probabilistic modeling, which can be used to detect somas and to eliminate cross talk effects. This work attempts to develop an automatic methodology for neuron image segmentation, which nowadays still lacks a complete solution due to the complexity of the image. The proposed method does not need any predetermined, risk-prone thresholds since biological information is inherently included in the image processing procedure. Therefore, it is less sensitive to variations in neuron morphology; meanwhile, its flexibility would be beneficial for tracing the intertwining structure of neurons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brainbow" title="brainbow">brainbow</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20imaging" title=" 3D imaging"> 3D imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20segmentation" title=" image segmentation"> image segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=neuron%20morphology" title=" neuron morphology"> neuron morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20data%20mining" title=" biological data mining"> biological data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=non-parametric%20learning" title=" non-parametric learning"> non-parametric learning</a> </p> <a href="https://publications.waset.org/abstracts/2189/brainbow-image-segmentation-using-bayesian-sequential-partitioning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2189.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">487</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Multiscale Connected Component Labelling and Applications to Scientific Microscopy Image Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yayun%20Hsu">Yayun Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Horng-Shing%20Lu"> Henry Horng-Shing Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new method is proposed to extending the method of connected component labeling from processing binary images to multi-scale modeling of images.

In addition, the computational cost of this approach remains similar to that of the typical approach of component labeling. Then, this methodology is applied to grain boundary detection and Drosophila Brain-bow neuron segmentation.

However, this scaffold is thought to have poor mechanical properties and rapid degradation, it is hard for cell recellularization. In this study, we used decellularized brain extracellular matrix combined with chitosan, which is naturally occurring polysaccharide and non-cytotoxic polymer, forming a 3-D scaffold for neural stem/precursor cells (NSPCs) regeneration. HE staining and DAPI fluorescence staining confirmed decellularized process could effectively vanish the cellular components from the brain. GAGs and collagen I, collagen IV were be showed a great preservation by Alcain staining and immunofluorescence staining respectively. Decellularized brain extracellular matrix was well mixed in chitosan to form a 3-D scaffold (DB-C scaffold). The pore size was approximately 50±10 μm examined by SEM images. Alamar blue results demonstrated NSPCs had great proliferation ability in DB-C scaffold. NSPCs that were cultured in this complex scaffold differentiated into neurons and astrocytes, as reveled by NSPCs expression of microtubule-associated protein 2 (MAP2) and glial fibrillary acidic protein (GFAP). In conclusion, DB-C scaffold may provide bioinformatics cues for NSPCs generation and aid for CNS injury functional recovery applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain" title="brain">brain</a>, <a href="https://publications.waset.org/abstracts/search?q=decellularization" title=" decellularization"> decellularization</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title=" scaffold"> scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20stem%2Fprecursor%20cells" title=" neural stem/precursor cells"> neural stem/precursor cells</a> </p> <a href="https://publications.waset.org/abstracts/41130/decellularized-brain-chitosan-scaffold-for-neural-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41130.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">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> MOOCs (E-Learning) Project Personnel Competency Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shang-Hua%20Wu">Shang-Hua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong-Chi%20Chang"> Rong-Chi Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Horng%E2%80%93Twu%20Liaw"> Horng–Twu Liaw</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, competencies of e-learning project personnel are very important in assisting them in offering courses, serving students in an effective way, leveraging advantages, strengthen their relationships with potential students, etc. among e-learning platforms, MOOCs has recently attracted increasing focuses in distance education since it can be conducted for a large numbers of virtual learners. Nonetheless, since MOOCs is a relatively new e-learning platform, top concerns have been paid to what competencies are important for e-learning personnel to consider. Taking this need, this research aimed to carry out an in-depth exploration of competency requirements of MOOCs (e-learning) project personnel in Taiwan vocational schools. Data were collected through thorough literature reviews and discussions and competency analysis was carried out using Delphi technique questionnaires. The results show that that MOOCs (e-learning) project personnel’ professional competency lie in three main dimensions, among which ‘demand analysis competency’ (i.e., containing 10 major competences and 48 subordinate capabilities) is the most important competency, followed by ‘project management competency’ (i.e., comprising 6 major competences and 31 secondary capabilities), and finally ‘digital content production competency’ (i.e., including 12 major competences and 79 secondary capabilities). As such, in Taiwan context with different organizational scales and market sizes, the e-learning competency items and unique experience/ achievements throughout the promotion process obtained in this research will provide useful references for academic institutions in promoting e-learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competency%20analysis" title="competency analysis">competency analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Delphi%20technique%20questionnaire" title=" Delphi technique questionnaire"> Delphi technique questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=massive%20open%20online%20courses" title=" massive open online courses"> massive open online courses</a> </p> <a href="https://publications.waset.org/abstracts/56037/moocs-e-learning-project-personnel-competency-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56037.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">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> An Application of Hip Arthroscopy after Acute Injury - A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Nguyen%20Binh">Le Nguyen Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Luong%20Xuan%20Binh"> Luong Xuan Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Van%20Tuan"> Le Van Tuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Binh%20Duong"> Tran Binh Duong</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Khanh%20Hung"> Truong Nguyen Khanh Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Le%20Hoang%20Son"> Do Le Hoang Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Pham%20Quang%20Vinh"> Pham Quang Vinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Quoc%20Huy"> Hoang Quoc Huy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Bach"> Nguyen Bach</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quoc%20Khanh%20Le"> Nguyen Quoc Khanh Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiunn%20Horng%20Kang"> Jiunn Horng Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Traumatic hip dislocation is an emergency in young adult which can cause avascular necrosis of femoral head or osteoarthritis of hip joint. The reasons for these may be the loose body of bony or chondral fragments, which are difficult to be detected on CT scan or MRI. In those cases, Hip arthroscopy may be the method of choice for diagnosis and treatment of loose bodies in hip joint after traumatic dislocation. Methods: A case report is performed. A 55-year-old male patient was under hip arthroscopy to retrieve the loose body in the right hip joint. Results: The patient’s hip was reduced under anesthesia in the opeation room. Xray and CT scan post-reduction showed that his right hip was wide and a small fragment of femoral head (< 5mm) locking inside the joint. A hip arthroscopy was done to take the fragment out. Post-operation, the patient went under rehabilition. After 6 months, he can walk with full-weight bearing; no further dislocaion was noted, and the Harris score was 84 points. Conclusions: Although acute traumatic injury of hip joint is usually treated with open surgeries, these methods have many drawbacks, such as soft tissue destruction, blood-loss,….Despite its technical requirement, hip arthroscopy is less invasive and effective treatment. Therefore, it may be an alternative treatment for a traumatic hip injury and can be applied frequently in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hip%20dislocation" title="hip dislocation">hip dislocation</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20arthroscopy" title=" hip arthroscopy"> hip arthroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20osteoarthritis" title=" hip osteoarthritis"> hip osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20hip%20trauma" title=" acute hip trauma"> acute hip trauma</a> </p> <a href="https://publications.waset.org/abstracts/162276/an-application-of-hip-arthroscopy-after-acute-injury-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162276.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">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Impact and Risk Assessment of Climate Change on Water Quality: A Study in the Errer River Basin, Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsin-Chih%20Lai">Hsin-Chih Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yung-Lung%20Lee"> Yung-Lung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Yao%20Chi"> Yun-Yao Chi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Yi%20Horng"> Ching-Yi Horng</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Chih%20Wu"> Pei-Chih Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsien-Chang%20Wang"> Hsien-Chang Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taiwan, a climatically challenged island, has always been keen on the issue of water resource management due to its limitations in water storage. Since water resource management has been the focal point of many adaptations to climate change, there has been a lack of attention on another issue, water quality. This study chooses the Errer River Basin as the experimental focus for water quality in Taiwan. With the Errer River Basin being one of the most polluted rivers in Taiwan, this study observes the effects of climate change on this river over a period of time. Taiwan is also targeted by multiple typhoons every year, the heavy rainfall and strong winds create problems of pollution being carried to different river segments, including into the ocean. This study aims to create an impact and risk assessment on Errer River Basin, to show the connection from climate change to potential extreme events, which in turn could influence water quality and ultimately human health. Using dynamic downscaling, this study narrows the information from a global scale to a resolution of 1 km x 1 km. Then, through interpolation, the resolution is further narrowed into a resolution of 200m x 200m, to analyze the past, present, and future of extreme events. According to different climate change scenarios, this study designs an assessment index on the vulnerability of the Errer River Basin. Through this index, Errer River inhabitants can access advice on adaptations to climate change and act accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation" title=" adaptation"> adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/57889/impact-and-risk-assessment-of-climate-change-on-water-quality-a-study-in-the-errer-river-basin-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57889.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">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Factors Affecting Internet Behavior and Life Satisfaction of Older Adult Learners with Use of Smartphone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Horng-Ji%20Lai">Horng-Ji Lai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The intuitive design features and friendly interface of smartphone attract older adults. In Taiwan, many senior education institutes offer smartphone training courses for older adult learners who are interested in learning this innovative technology. It is expected that the training courses can help them to enjoy the benefits of using smartphone and increase their life satisfaction. Therefore, it is important to investigate the factors that influence older adults’ behavior of using smartphone. The purpose of the research was to develop and test a research model that investigates the factors (self-efficacy, social connection, the need to seek health information, and the need to seek financial information) affecting older adult learners’ Internet behaviour and their life satisfaction with use of smartphone. Also, this research sought to identify the relationship between the proposed variables. Survey method was used to collect research data. A Structural Equation Modeling was performed using Partial Least Squares (PLS) regression for data exploration and model estimation. The participants were 394 older adult learners from smartphone training courses in active aging learning centers located in central Taiwan. The research results revealed that self-efficacy significantly affected older adult learner’ social connection, the need to seek health information, and the need to seek financial information. The construct of social connection yielded a positive influence in respondents’ life satisfaction. The implications of these results for practice and future research are also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title="older adults">older adults</a>, <a href="https://publications.waset.org/abstracts/search?q=smartphone" title=" smartphone"> smartphone</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20behaviour" title=" internet behaviour"> internet behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20satisfaction" title=" life satisfaction"> life satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/76387/factors-affecting-internet-behavior-and-life-satisfaction-of-older-adult-learners-with-use-of-smartphone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76387.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">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Solar-Blind Ni-Schottky Photodetector Based on MOCVD Grown ZnGa₂O₄</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taslim%20Khan">Taslim Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ray%20Hua%20Horng"> Ray Hua Horng</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajendra%20Singh"> Rajendra Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a comprehensive analysis of the design, fabrication, and performance evaluation of a solar-blind Schottky photodetector based on ZnGa₂O₄ grown via MOCVD, utilizing Ni/Au as the Schottky electrode. ZnGa₂O₄, with its wide bandgap of 5.2 eV, is well-suited for high-performance solar-blind photodetection applications. The photodetector demonstrates an impressive responsivity of 280 A/W, indicating its exceptional sensitivity within the solar-blind ultraviolet band. One of the device's notable attributes is its high rejection ratio of 10⁵, which effectively filters out unwanted background signals, enhancing its reliability in various environments. The photodetector also boasts a photodetector responsivity contrast ratio (PDCR) of 10⁷, showcasing its ability to detect even minor changes in incident UV light. Additionally, the device features an outstanding detective of 10¹⁸ Jones, underscoring its capability to precisely detect faint UV signals. It exhibits a fast response time of 80 ms and an ON/OFF ratio of 10⁵, making it suitable for real-time UV sensing applications. The noise-equivalent power (NEP) of 10^-17 W/Hz further highlights its efficiency in detecting low-intensity UV signals. The photodetector also achieves a high forward-to-backward current rejection ratio of 10⁶, ensuring high selectivity. Furthermore, the device maintains an extremely low dark current of approximately 0.1 pA. These findings position the ZnGa₂O₄-based Schottky photodetector as a leading candidate for solar-blind UV detection applications. It offers a compelling combination of sensitivity, selectivity, and operational efficiency, making it a highly promising tool for environments requiring precise and reliable UV detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wideband%20gap" title="wideband gap">wideband gap</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20blind%20photodetector" title=" solar blind photodetector"> solar blind photodetector</a>, <a href="https://publications.waset.org/abstracts/search?q=MOCVD" title=" MOCVD"> MOCVD</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20gallate" title=" zinc gallate"> zinc gallate</a> </p> <a href="https://publications.waset.org/abstracts/186831/solar-blind-ni-schottky-photodetector-based-on-mocvd-grown-znga2o4" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186831.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">39</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">5</span> Effectiveness of Control Measures for Ambient Fine Particulate Matters Concentration Improvement in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiun-Horng%20Tsai">Jiun-Horng Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi-Jie"> Shi-Jie</a>, <a href="https://publications.waset.org/abstracts/search?q=Nieh"> Nieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fine particulate matter (PM₂.₅) has become an important issue all over the world over the last decade. Annual mean PM₂.₅ concentration has been over the ambient air quality standard of PM₂.₅ (annual average concentration as 15μg/m³) which adapted by Taiwan Environmental Protection Administration (TEPA). TEPA, therefore, has developed a number of air pollution control measures to improve the ambient concentration by reducing the emissions of primary fine particulate matter and the precursors of secondary PM₂.₅. This study investigated the potential improvement of ambient PM₂.₅ concentration by the TEPA program and the other scenario for further emission reduction on various sources. Four scenarios had been evaluated in this study, including a basic case and three reduction scenarios (A to C). The ambient PM₂.₅ concentration was evaluated by Community Multi-scale Air Quality modelling system (CMAQ) ver. 4.7.1 along with the Weather Research and Forecasting Model (WRF) ver. 3.4.1. The grid resolutions in the modelling work are 81 km × 81 km for domain 1 (covers East Asia), 27 km × 27 km for domain 2 (covers Southeast China and Taiwan), and 9 km × 9 km for domain 3 (covers Taiwan). The result of PM₂.₅ concentration simulation in different regions of Taiwan shows that the annual average concentration of basic case is 24.9 μg/m³, and are 22.6, 18.8, and 11.3 μg/m³, respectively, for scenarios A to C. The annual average concentration of PM₂.₅ would be reduced by 9-55 % for those control scenarios. The result of scenario C (the emissions of precursors reduce to allowance levels) could improve effectively the airborne PM₂.₅ concentration to attain the air quality standard. According to the results of unit precursor reduction contribution, the allowance emissions of PM₂.₅, SOₓ, and NOₓ are 16.8, 39, and 62 thousand tons per year, respectively. In the Kao-Ping air basin, the priority for reducing precursor emissions is PM₂.₅ > NOₓ > SOₓ, whereas the priority for reducing precursor emissions is PM₂.₅ > SOₓ > NOₓ in others area. The result indicates that the target pollutants that need to be reduced in different air basin are different, and the control measures need to be adapted to local conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airborne%20PM%E2%82%82.%E2%82%85" title="airborne PM₂.₅">airborne PM₂.₅</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20multi-scale%20air%20quality%20modelling%20system" title=" community multi-scale air quality modelling system"> community multi-scale air quality modelling system</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20measures" title=" control measures"> control measures</a>, <a href="https://publications.waset.org/abstracts/search?q=weather%20research%20and%20forecasting%20model" title=" weather research and forecasting model"> weather research and forecasting model</a> </p> <a href="https://publications.waset.org/abstracts/99765/effectiveness-of-control-measures-for-ambient-fine-particulate-matters-concentration-improvement-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99765.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">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Assessment and Adaptation Strategy of Climate Change to Water Quality in the Erren River and Its Impact to Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pei-Chih%20Wu">Pei-Chih Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Chih%20Lai"> Hsin-Chih Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yung-Lung%20Lee"> Yung-Lung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Yao%20Chi"> Yun-Yao Chi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Yi%20Horng"> Ching-Yi Horng</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsien-Chang%20Wang"> Hsien-Chang Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of climate change to health has always been well documented. Amongst them, water-borne infectious diseases, chronic adverse effects or cancer risks due to chemical contamination in flooding or drought events are especially important in river basin. This study therefore utilizes GIS and different models to integrate demographic, land use, disaster prevention, social-economic factors, and human health assessment in the Erren River basin. Therefore, through the collecting of climatic, demographic, health surveillance, water quality and other water monitoring data, potential risks associated with the Erren River Basin are established and to understand human exposure and vulnerability in response to climate extremes. This study assesses the temporal and spatial patterns of melioidosis (2000-2015) and various cancer incidents in Tainan and Kaohsiung cities. The next step is to analyze the spatial association between diseases incidences, climatic factors, land uses, and other demographic factors by using ArcMap and GeoDa. The study results show that amongst all melioidosis cases in Taiwan, 24% cases (115) residence occurred in the Erren River basin. The relationship between the cases and in Tainan and Kaohsiung cities are associated with population density, aging indicator, and residence in Erren River basin. Risks from flooding due to heavy rainfall and fish farms in spatial lag regression are also related. Through liver cancer, the preliminary analysis in temporal and spatial pattern shows an increases pattern in annual incidence without clusters in Erren River basin. Further analysis of potential cancers connected to heavy metal contamination from water pollution in Erren River is established. The final step is to develop an assessment tool for human exposure from water contamination and vulnerability in response to climate extremes for the second year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20impact" title=" health impact"> health impact</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20adaptation" title=" health adaptation"> health adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=Erren%20River%20Basin" title=" Erren River Basin"> Erren River Basin</a> </p> <a href="https://publications.waset.org/abstracts/58877/assessment-and-adaptation-strategy-of-climate-change-to-water-quality-in-the-erren-river-and-its-impact-to-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58877.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">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> The Improved Therapeutic Effect of Trans-Cinnamaldehyde on Adipose-Derived Stem Cells without Chemical Induction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karthyayani%20Rajamani">Karthyayani Rajamani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Chun%20Lin"> Yi-Chun Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tung-Chou%20Wen"> Tung-Chou Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeanne%20Hsieh"> Jeanne Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Maun%20Subeq"> Yi-Maun Subeq</a>, <a href="https://publications.waset.org/abstracts/search?q=Jen-Wei%20Liu"> Jen-Wei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Po-Cheng%20Lin"> Po-Cheng Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Horng-Jyh%20Harn"> Horng-Jyh Harn</a>, <a href="https://publications.waset.org/abstracts/search?q=Shinn-Zong%20Lin"> Shinn-Zong Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzyy-Wen%20Chiou"> Tzyy-Wen Chiou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assuring cell quality is an essential parameter for the success of stem cell therapy, utilization of various components to improve this potential has been the primary goal of stem cell research. The aim of this study was not only to demonstrate the capacity of trans-cinnamaldehyde (TC) to reverse stress-induced senescence but also improve the therapeutic abilities of stem cells. Because of the availability and the promising application potential in regenerative medicine, adipose-derived stem cells (ADSCs) were chosen for the study. We found that H2O2 treatment resulted in the expression of senescence characteristics in the ADSCs, including decreased proliferation rate, increased senescence-associated- β-galactosidase (SA-β-gal) activity, decreased SIRT1 (silent mating type information regulation 2 homologs) expression and decreased telomerase activity. However, TC treatment was sufficient to rescue or reduce the effects of H2O2 induction, ultimately leading to an increased proliferation rate, a decrease in the percentage of SA-β-gal positive cells, upregulation of SIRT1 expression, and increased telomerase activity of the senescent ADSCs at the cellular level. Further recently it was observed that the ADSCs were treated with TC without induction of senescence, all the before said positives were observed. Moreover, a chemically induced liver fibrosis animal model was used to evaluate the functionality of these rescued cells in vivo. Liver dysfunction was established by injecting 200 mg/kg thioacetamide (TAA) intraperitoneally into Wistar rats every third day for 60 days. The experimental rats were separated into groups; normal group (rats without TAA induction), sham group (without ADSC transplantation), positive control group (transplanted with normal ADSCs); H2O2 group (transplanted with H2O2 -induced senescent ADSCs), H2O2+TC group (transplanted with ADSCs pretreated with H2O2 and then further treated with TC) and TC group (ADSC treated with TC without H2O2 treatment). In the transplantation group, 1 × 106 human ADSCs were introduced into each rat via direct liver injection. Based on the biochemical analysis and immunohistochemical staining results, it was determined that the therapeutic effects on liver fibrosis by the induced senescent ADSCs (H2O2 group) were not as significant as those exerted by the normal ADSCs (the positive control group). However, the H2O2+TC group showed significant reversal of liver damage when compared to the H2O2 group 1 week post-transplantation. Further ADSCs without H2O2 treatment but with just TC treatment performed much better than all the groups. These data confirmed that the TC treatment had the potential to improve the therapeutic effect of ADSCs. It is therefore suggested that TC has potential applications in maintaining stem cell quality and could possibly aid in the treatment of senescence-related disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=senescence" title="senescence">senescence</a>, <a href="https://publications.waset.org/abstracts/search?q=SIRT1" title=" SIRT1"> SIRT1</a>, <a href="https://publications.waset.org/abstracts/search?q=adipose%20derived%20stem%20cells" title=" adipose derived stem cells"> adipose derived stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20fibrosis" title=" liver fibrosis"> liver fibrosis</a> </p> <a href="https://publications.waset.org/abstracts/41305/the-improved-therapeutic-effect-of-trans-cinnamaldehyde-on-adipose-derived-stem-cells-without-chemical-induction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41305.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">258</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> A Comprehensive Survey of Artificial Intelligence and Machine Learning Approaches across Distinct Phases of Wildland Fire Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ursula%20Das">Ursula Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Manavjit%20Singh%20Dhindsa"> Manavjit Singh Dhindsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kshirasagar%20Naik"> Kshirasagar Naik</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzia%20Zaman"> Marzia Zaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Purcell"> Richard Purcell</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivas%20Sampalli"> Srinivas Sampalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Mutakabbir"> Abdul Mutakabbir</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Horng%20Lung"> Chung-Horng Lung</a>, <a href="https://publications.waset.org/abstracts/search?q=Thambirajah%20Ravichandran"> Thambirajah Ravichandran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wildland fires, also known as forest fires or wildfires, are exhibiting an alarming surge in frequency in recent times, further adding to its perennial global concern. Forest fires often lead to devastating consequences ranging from loss of healthy forest foliage and wildlife to substantial economic losses and the tragic loss of human lives. Despite the existence of substantial literature on the detection of active forest fires, numerous potential research avenues in forest fire management, such as preventative measures and ancillary effects of forest fires, remain largely underexplored. This paper undertakes a systematic review of these underexplored areas in forest fire research, meticulously categorizing them into distinct phases, namely pre-fire, during-fire, and post-fire stages. The pre-fire phase encompasses the assessment of fire risk, analysis of fuel properties, and other activities aimed at preventing or reducing the risk of forest fires. The during-fire phase includes activities aimed at reducing the impact of active forest fires, such as the detection and localization of active fires, optimization of wildfire suppression methods, and prediction of the behavior of active fires. The post-fire phase involves analyzing the impact of forest fires on various aspects, such as the extent of damage in forest areas, post-fire regeneration of forests, impact on wildlife, economic losses, and health impacts from byproducts produced during burning. A comprehensive understanding of the three stages is imperative for effective forest fire management and mitigation of the impact of forest fires on both ecological systems and human well-being. Artificial intelligence and machine learning (AI/ML) methods have garnered much attention in the cyber-physical systems domain in recent times leading to their adoption in decision-making in diverse applications including disaster management. This paper explores the current state of AI/ML applications for managing the activities in the aforementioned phases of forest fire. While conventional machine learning and deep learning methods have been extensively explored for the prevention, detection, and management of forest fires, a systematic classification of these methods into distinct AI research domains is conspicuously absent. This paper gives a comprehensive overview of the state of forest fire research across more recent and prominent AI/ML disciplines, including big data, classical machine learning, computer vision, explainable AI, generative AI, natural language processing, optimization algorithms, and time series forecasting. By providing a detailed overview of the potential areas of research and identifying the diverse ways AI/ML can be employed in forest fire research, this paper aims to serve as a roadmap for future investigations in this domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=during-fire%20activities" title=" during-fire activities"> during-fire activities</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20fire%20management" title=" forest fire management"> forest fire management</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-fire%20activities" title=" pre-fire activities"> pre-fire activities</a>, <a href="https://publications.waset.org/abstracts/search?q=post-fire%20activities" title=" post-fire activities"> post-fire activities</a> </p> <a href="https://publications.waset.org/abstracts/176766/a-comprehensive-survey-of-artificial-intelligence-and-machine-learning-approaches-across-distinct-phases-of-wildland-fire-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176766.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">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> A Comprehensive Study of Spread Models of Wildland Fires</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manavjit%20Singh%20Dhindsa">Manavjit Singh Dhindsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ursula%20Das"> Ursula Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Kshirasagar%20Naik"> Kshirasagar Naik</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzia%20Zaman"> Marzia Zaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Purcell"> Richard Purcell</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivas%20Sampalli"> Srinivas Sampalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Mutakabbir"> Abdul Mutakabbir</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Horng%20Lung"> Chung-Horng Lung</a>, <a href="https://publications.waset.org/abstracts/search?q=Thambirajah%20Ravichandran"> Thambirajah Ravichandran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> These days, wildland fires, also known as forest fires, are more prevalent than ever. Wildfires have major repercussions that affect ecosystems, communities, and the environment in several ways. Wildfires lead to habitat destruction and biodiversity loss, affecting ecosystems and causing soil erosion. They also contribute to poor air quality by releasing smoke and pollutants that pose health risks, especially for individuals with respiratory conditions. Wildfires can damage infrastructure, disrupt communities, and cause economic losses. The economic impact of firefighting efforts, combined with their direct effects on forestry and agriculture, causes significant financial difficulties for the areas impacted. This research explores different forest fire spread models and presents a comprehensive review of various techniques and methodologies used in the field. A forest fire spread model is a computational or mathematical representation that is used to simulate and predict the behavior of a forest fire. By applying scientific concepts and data from empirical studies, these models attempt to capture the intricate dynamics of how a fire spreads, taking into consideration a variety of factors like weather patterns, topography, fuel types, and environmental conditions. These models assist authorities in understanding and forecasting the potential trajectory and intensity of a wildfire. Emphasizing the need for a comprehensive understanding of wildfire dynamics, this research explores the approaches, assumptions, and findings derived from various models. By using a comparison approach, a critical analysis is provided by identifying patterns, strengths, and weaknesses among these models. The purpose of the survey is to further wildfire research and management techniques. Decision-makers, researchers, and practitioners can benefit from the useful insights that are provided by synthesizing established information. Fire spread models provide insights into potential fire behavior, facilitating authorities to make informed decisions about evacuation activities, allocating resources for fire-fighting efforts, and planning for preventive actions. Wildfire spread models are also useful in post-wildfire mitigation strategies as they help in assessing the fire's severity, determining high-risk regions for post-fire dangers, and forecasting soil erosion trends. The analysis highlights the importance of customized modeling approaches for various circumstances and promotes our understanding of the way forest fires spread. Some of the known models in this field are Rothermel’s wildland fuel model, FARSITE, WRF-SFIRE, FIRETEC, FlamMap, FSPro, cellular automata model, and others. The key characteristics that these models consider include weather (includes factors such as wind speed and direction), topography (includes factors like landscape elevation), and fuel availability (includes factors like types of vegetation) among other factors. The models discussed are physics-based, data-driven, or hybrid models, also utilizing ML techniques like attention-based neural networks to enhance the performance of the model. In order to lessen the destructive effects of forest fires, this initiative aims to promote the development of more precise prediction tools and effective management techniques.
