The scheme of direct synthesis of DMC from CO₂ and Methanol is 'CO₂ + 2MeOH ↔ DMC + H₂O'. Among them, reactants are CO₂ and MeOH, product is DMC, and byproduct is H₂O (water). According to Le Chatelier’s principle, removing byproduct (water) can shift the reaction equilibrium to the right (DMC production). The main purpose of this process is removing water during the reaction. For efficient in situ water removal (dehydration) and DMC separation, zeolite 4A membranes with very small pore diameter and hydrophilicity were introduced. In this study, pervaporation performances of binary and ternary DMC / methanol / water mixtures were evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dimehtyl%20carbonate" title="dimehtyl carbonate">dimehtyl carbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol" title=" methanol"> methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite%20membrane" title=" zeolite membrane"> zeolite membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=pervaporation" title=" pervaporation"> pervaporation</a> </p> <a href="https://publications.waset.org/abstracts/71361/pervaporation-of-dimethyl-carbonate-methanol-water-mixtures-using-zeolite-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71361.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">362</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">155</span> Iterative Panel RC Extraction for Capacitive Touchscreen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chae%20Hoon%20Park">Chae Hoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Kang%20Park"> Jong Kang Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Tae%20Kim"> Jong Tae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical characteristics of capacitive touchscreen need to be accurately analyzed to result in better performance for multi-channel capacitance sensing.

One of the key applications is to recognize the user location by indoor illuminators such as light emitting diodes. For localization of individual receivers in these systems, we usually assume that receivers and transmitters are placed in parallel. However, it is difficult to satisfy this assumption because the receivers move randomly in real case. It is necessary to analyze the case when transmitter is not placed perfectly parallel to receiver. It is also important to identify changes on optical gain by the tilted angles and distances of them against the illuminators. In this paper, we simulate optical gain for various cases where the tilt of the receiver and the distance change. Then, we identified changing patterns of optical gains according to tilted angles of a receiver and distance. These results can help many VLC applications understand the extent of the location errors with regard to optical gains of the receivers and identify the root cause. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visible%20light%20communication" title="visible light communication">visible light communication</a>, <a href="https://publications.waset.org/abstracts/search?q=incident%20angle" title=" incident angle"> incident angle</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20gain" title=" optical gain"> optical gain</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20emitting%20diode" title=" light emitting diode"> light emitting diode</a> </p> <a href="https://publications.waset.org/abstracts/60436/effects-of-incident-angle-and-distance-on-visible-light-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60436.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">335</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> Single Event Transient Tolerance Analysis in 8051 Microprocessor Using Scan Chain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Sung%20Go">Jun Sung Go</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Kang%20Park"> Jong Kang Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Tae%20Kim"> Jong Tae Kim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> As semi-conductor manufacturing technology evolves; the single event transient problem becomes more significant issue. Single event transient has a critical impact on both combinational and sequential logic circuits, so it is important to evaluate the soft error tolerance of the circuits at the design stage. In this paper, we present a soft error detecting simulation using scan chain. The simulation model generates a single event transient randomly in the circuit, and detects the soft error during the execution of the test patterns. We verified this model by inserting a scan chain in an 8051 microprocessor using 65 nm CMOS technology. While the test patterns generated by ATPG program are passing through the scan chain, we insert a single event transient and detect the number of soft errors per sub-module. The experiments show that the soft error rates per cell area of the SFR module is 277% larger than other modules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scan%20chain" title="scan chain">scan chain</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20event%20transient" title=" single event transient"> single event transient</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20error" title=" soft error"> soft error</a>, <a href="https://publications.waset.org/abstracts/search?q=8051%20processor" title=" 8051 processor"> 8051 processor</a> </p> <a href="https://publications.waset.org/abstracts/60435/single-event-transient-tolerance-analysis-in-8051-microprocessor-using-scan-chain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60435.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">347</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> The Effect of Remifentanil on Emergence Agitation after Sevoflurane Anesthesia in Children: A Meta-Analysis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong%20Yeop%20Kim">Jong Yeop Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Young%20Park"> Sung Young Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Hee%20Kim"> Dae Hee Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Bum%20Joe"> Han Bum Joe</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Young%20Yoo"> Ji Young Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Bum%20Choi"> Jong Bum Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sook%20Young%20Lee"> Sook Young Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emergence agitation (EA) is commonly reported adverse events after sevoflurane anesthesia in pediatric patients.

The number of patients of reporting EA was summarized using risk ratio (RR) with 95% confidence interval (CI), with point estimates and 95CIs derived from a random effects Mantel-Haenszel method. Overall incidence of EA was about 41%. Compared with sevoflurane alone anesthesia, intravenous infusion of remifentanil with sevoflurane significantly reduced the incidence of EA (RR 0.53, 95% CI 0.39-0.73, P < 0.0001), (heterogeneity, I2 = 0, P = 0.42). This meta-analysis suggested that continuous infusion of remifentanil could be effective in decreasing the EA of about 47% after sevoflurane anesthesia. However, considering limitations of the included studies, more randomized controlled studies are required to verify our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergence%20agitation" title="emergence agitation">emergence agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=remifentanil" title=" remifentanil"> remifentanil</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a> </p> <a href="https://publications.waset.org/abstracts/76607/the-effect-of-remifentanil-on-emergence-agitation-after-sevoflurane-anesthesia-in-children-a-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76607.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">375</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">148</span> Comparison of Remifentanil EC50 for Facilitating I-Gel and Laryngeal Mask Airway Insertion with Propofol Anesthesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong%20Yeop%20Kim">Jong Yeop Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Bum%20Choi"> Jong Bum Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Jeong%20Kwak"> Hyun Jeong Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Sook%20Young%20Lee"> Sook Young Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Each supraglottic airway requires different anesthetic depth because it has a specific structure and different compressive force in the oropharyngeal cavity. We designed the study to investigate remifentanil effect-site concentration (Ce) in 50% of patients (EC50) for successful insertion of i- gel, and to compare it with that for laryngeal mask airway (LMA) insertion during propofol target-controlled infusion (TCI). Methods: Forty-one female patients were randomized to the i-gel group (n=20) or the LMA group (n=21). Anesthesia induction was performed using propofol Ce of 5 μg/ml and the predetermined remifentanil Ce, and i-gel or LMA insertion was attempted 5 min later. The remifentanil Ce was estimated by modified Dixon's up-and-down method (initial concentration: 3.0 ng/ml, step size: 0.5 ng/ml). The patient’s response to device insertion was classified as either ‘success (no movement)’ or ‘failure (movement)’. Results: Using the Dixon’s up and down method, EC50 of remifentanil Ce for i-gel (1.58 ± 0.41 ng/ml) was significantly lower than that for LMA (2.25 ± 0.55 ng/ml) (p=0.038). Using isotonic regression, EC50 (83% CI) of remifentanil in the i-gel group [1.50 (1.37-1.80) ng/ml] was statistically lower than that in the LMA group [2.00 (1.82-2.34) ng/ml]. EC95 (95% CI) of remifentanil in the i-gel group [2.38 (1.48-2.50) ng/ml] was statistically lower than that in the LMA group [3.35 (2.58-3.48) ng/ml]. Conclusion: We found that EC50 of remifentanil Ce for i-gel insertion (1.58 ng/ml) was significantly lower than that for LMA insertion (2.25 ng/ml), in female patients during propofol TCI without neuromuscular blockade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=i-gel" title="i-gel">i-gel</a>, <a href="https://publications.waset.org/abstracts/search?q=laryngeal%20mask%20airway" title=" laryngeal mask airway"> laryngeal mask airway</a>, <a href="https://publications.waset.org/abstracts/search?q=propofol" title=" propofol"> propofol</a>, <a href="https://publications.waset.org/abstracts/search?q=remifentanil" title=" remifentanil"> remifentanil</a> </p> <a href="https://publications.waset.org/abstracts/42987/comparison-of-remifentanil-ec50-for-facilitating-i-gel-and-laryngeal-mask-airway-insertion-with-propofol-anesthesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42987.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">147</span> Integrated Simulation and Optimization for Carbon Capture and Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taekyoon%20Park">Taekyoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokgoo%20Lee"> Seokgoo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungho%20Kim"> Sungho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ung%20Lee"> Ung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chonghun%20Han"> Chonghun Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO2 capture and storage/sequestration (CCS) is a key technology for addressing the global warming issue.

We, therefore attempted to analyze the factors to cause the death in NMD patients from our cohort. Methods：From 1998 to 2013, we retrospectively collected the information of the NMD patients treated and followed up in Kaohsiung Medical University Hospital. Forty-two patients with NMD who expired during these fifteen years were enrolled. The medical records of these patients were reviewed and the causes of death and the associated affecting factors were analyzed. Results：Eighteen patients with NMD (mean age=13.3, SD=12.4) with complete medical record and detailed information were finally included in this study, including spinal muscular atrophy (SMA) (n=9, 7/9: type 1), Duchenne muscular dystrophy (n=6), congenital muscular dystrophy (n=1), carnitine acyl-carnitine translocase (CACT) deficiency (n=1) and spinal muscular atrophy with respiratory distress (SMARD)(n=1). The place of death was in ICU (n=11, 61%), emergency room (n=3, 16.6%) or home (n=4, 22.2%). For SMA type 1 patients, most of them (71.4%, 5/7) died in emergency room or home and the other two expired during an ICU admission. The causes of death included acute respiratory failure due to pneumonia (n=13, 72.2 %), ventilator failure or dislocation (n=2, 11.1%), suffocation/choking (n=2, 11.1%), and heart failure with hypertrophic cardiomyopathy (n=1, 5.55%). Among the 15 patients died of respiratory failure or choking, 73.3% of the patients (n=11) received no ventilator care at home. 80% of the patients (n=12) received no cough assist at home. The patient died of cardiomyopathy received no medications for heart failure until the last admission. Conclusion: Respiratory failure and choking are the leading causes of death in NMD patients. Appropriate respiratory support and airway clearance play the critical role to reduce the mortality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuromuscular%20disease" title="neuromuscular disease">neuromuscular disease</a>, <a href="https://publications.waset.org/abstracts/search?q=cause%20of%20death" title=" cause of death"> cause of death</a>, <a href="https://publications.waset.org/abstracts/search?q=tertiary%20care%20hospital" title=" tertiary care hospital"> tertiary care hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20sciences" title=" medical sciences"> medical sciences</a> </p> <a href="https://publications.waset.org/abstracts/14948/causes-of-death-in-neuromuscular-disease-patients-15-year-experience-in-a-tertiary-care-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14948.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">532</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">145</span> Disaster Response Training Simulator Based on Augmented Reality, Virtual Reality, and MPEG-DASH</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunho%20Seo">Sunho Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Younghwan%20Shin"> Younghwan Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Hong%20Park"> Jong-Hong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sooeun%20Song"> Sooeun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Junsung%20Kim"> Junsung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jusik%20Yun"> Jusik Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongkyun%20Kim"> Yongkyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Moon%20Chung"> Jong-Moon Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to effectively cope with large and complex disasters, disaster response training is needed. Recently, disaster response training led by the ROK (Republic of Korea) government is being implemented through a 4 year R&D project, which has several similar functions as the HSEEP (Homeland Security Exercise and Evaluation Program) of the United States, but also has several different features as well. Due to the unpredictiveness and diversity of disasters, existing training methods have many limitations in providing experience in the efficient use of disaster incident response and recovery resources. Always, the challenge is to be as efficient and effective as possible using the limited human and material/physical resources available based on the given time and environmental circumstances. To enable repeated training under diverse scenarios, an AR (Augmented Reality) and VR (Virtual Reality) combined simulator is under development. Unlike existing disaster response training, simulator based training (that allows remote login simultaneous multi-user training) enables freedom from limitations in time and space constraints, and can be repeatedly trained with different combinations of functions and disaster situations. There are related systems such as ADMS (Advanced Disaster Management Simulator) developed by ETC simulation and HLS2 (Homeland Security Simulation System) developed by ELBIT system. However, the ROK government needs a simulator custom made to the country's environment and disaster types, and also combines the latest information and communication technologies, which include AR, VR, and MPEG-DASH (Moving Picture Experts Group - Dynamic Adaptive Streaming over HTTP) technology. In this paper, a new disaster response training simulator is proposed to overcome the limitation of existing training systems, and adapted to actual disaster situations in the ROK, where several technical features are described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title="augmented reality">augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response%20training%20simulator" title=" emergency response training simulator"> emergency response training simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=MPEG-DASH" title=" MPEG-DASH"> MPEG-DASH</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a> </p> <a href="https://publications.waset.org/abstracts/67510/disaster-response-training-simulator-based-on-augmented-reality-virtual-reality-and-mpeg-dash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">144</span> The Development of a Cyber Violence Measurement Tool for Youths: A Multi-Reporting of Ecological Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Hyo%20Park">Jong-Hyo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunyoung%20Choi"> Eunyoung Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Yeon%20Lim"> Jae-Yeon Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seon-Suk%20Lee"> Seon-Suk Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeong-Rong%20Koo"> Yeong-Rong Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Ung%20Kwon"> Ji-Ung Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Sung%20Kim"> Kyung-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ik%20Lee"> Jong-Ik Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Juhan%20Park"> Juhan Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kyu%20Lee"> Hyun-Kyu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Won-Kyoung%20Oh"> Won-Kyoung Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jisang%20Lee"> Jisang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiwon%20Choe"> Jiwon Choe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to COVID-19, cyber violence among youths has soared as they spend more time online than before. In contrast to the deepening concerns, measurement tools that can assess the vulnerability of cyber violence in individual youths still need to be supplemented. The measurement tools lack consideration of various factors related to cyber violence among youths. Most of the tools are self-report questionnaires, and these adolescents' self-report questionnaire forms can underestimate the harmful behavior and overestimate the damage experience. Therefore, this study aims to develop a multi-report measurement tool for youths that can reliably measure individuals' ecological factors related to cyber violence. The literature review explored factors related to cyber violence, and the questions were constructed. The face validity of the questions was confirmed by conducting focus group interviews. Exploratory and confirmatory factor analyses (N=671) were also conducted for statistical validation. This study developed a multi-report measurement tool for cyber violence with 161 questions, consisting of six domains: online behavior, cyber violence awareness, victimization-perpetration-witness experience, coping efficacy (individuals, peers, teachers, and parents), psychological characteristics, and pro-social capabilities. In addition to self-report from a youth respondent, this measurement tool includes peers, teachers, and parents reporting for the respondent. It is possible to reliably measure the ecological factors of individual youths who are vulnerable or highly resistant to cyber violence. In schools, teachers could refer to the measurement results for guiding students, better understanding their cyber violence conditions, and assessing their pro-social capabilities. With the measurement results, teachers and police officers could detect perpetrators or victims and intervene immediately. In addition, this measurement tool could analyze the effects of the prevention and intervention programs for cyber violence and draw appropriate suggestions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescents" title="adolescents">adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20violence" title=" cyber violence"> cyber violence</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20violence%20measurement%20tool" title=" cyber violence measurement tool"> cyber violence measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20tool" title=" measurement tool"> measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-report%20measurement%20tool" title=" multi-report measurement tool"> multi-report measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=youths" title=" youths"> youths</a> </p> <a href="https://publications.waset.org/abstracts/155962/the-development-of-a-cyber-violence-measurement-tool-for-youths-a-multi-reporting-of-ecological-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155962.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">101</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">143</span> Design of Local Interconnect Network Controller for Automotive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Bae%20Lee">Jong-Bae Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seongsoo%20Lee"> Seongsoo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Local interconnect network (LIN) is a communication protocol that combines sensors, actuators, and processors to a functional module in automotive applications.

However, the reaction mechanism of w-TA has been not well studied, contrary to a-transaminase (a-TA) such as AspTA. Here, we propose in silico model on the reaction mechanism of w-TA. Based on the modeling results which showed large free energy gaps between external aldimine and quinonoid on deamination (or ketimine and quinonoid on amination), withdrawal of Ca-H seemed as a critical step which determines the reaction rate on both amination and deamination reactions, which is consistent with previous researches. Hyperconjugation was also observed in both external aldimine and ketimine which weakens Ca-H bond to elevate Ca-H abstraction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20modeling" title="computational modeling">computational modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=reaction%20intermediates" title=" reaction intermediates"> reaction intermediates</a>, <a href="https://publications.waset.org/abstracts/search?q=w-transaminase" title=" w-transaminase"> w-transaminase</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silico%20model" title=" in silico model"> in silico model</a> </p> <a href="https://publications.waset.org/abstracts/23667/in-silico-model-of-transamination-reaction-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">544</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> Implementation of Sensor Fusion Structure of 9-Axis Sensors on the Multipoint Control Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Gil%20Ahn">Jun Gil Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Tae%20Kim"> Jong Tae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the sensor fusion structure on the multipoint control unit (MCU).

Although some progress has been made to improve PSO algorithms over the last two decades, additional work is still needed to balance parameters to achieve better numerical properties of accuracy, efficiency, and stability. In the optimal PSO algorithm, the optimal weightings of (√ 5 − 1)/2 and (3 − √5)/2 are used for the cognitive factor and the social factor, respectively. By the same token, the same optimal weightings have been applied for intensification searches and diversification searches, respectively. Perturbation and constriction effects are optimally balanced. Simulations of the de Jong, the Rosenbrock, and the Griewank functions show that the optimal PSO algorithm indeed achieves better numerical properties and outperforms the canonical PSO algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diversification%20search" title="diversification search">diversification search</a>, <a href="https://publications.waset.org/abstracts/search?q=intensification%20search" title=" intensification search"> intensification search</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20weighting" title=" optimal weighting"> optimal weighting</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a> </p> <a href="https://publications.waset.org/abstracts/36390/optimized-algorithm-for-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36390.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">581</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">129</span> A Ratiometric Inorganic Phosphate Sensor Based on CdSe/ZnS QDs and Rhodamine 6G-Doped Nanofibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Dinh%20Duong">Hong Dinh Duong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Il%20Rhee"> Jong Il Rhee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a ratiometric inorganic phosphate sensor was fabricated by a double layer of the rhodamine 6G-doped nanofibers and the CdSe/ZnS QDs-captured polymer. In which, CdSe/ZnS QDs with emission wavelengths of 595nm were synthesized and ligands on their surface were exchanged with mercaptopropionic acid (MPA). The synthesized MPA-QDs were combined with the mixture of sol-gel of 3-glycidoxypropyl trimethoxysilane (GPTMS), 3-aminopropyltrimethoxysilane (APTMS) and polyurethane (PU) to build a layer for sensing inorganic phosphate. Another sensing layer was of nanofibers doped R6G which were produced from poly(styrene-co-acrylonitrile) by electrospining. The ratio of fluorescence intensities between rhodamin 6G (R6G) and CdSe/ZnS QDs exposed at different phosphate concentrations was used for calculating a linear phosphate concentration range of 0-10mM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title="nanofiber">nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=QDs" title=" QDs"> QDs</a>, <a href="https://publications.waset.org/abstracts/search?q=ratiometric%20phosphate%20sensor" title=" ratiometric phosphate sensor"> ratiometric phosphate sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=rhodamine%206G" title=" rhodamine 6G"> rhodamine 6G</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel" title=" sol-gel"> sol-gel</a> </p> <a href="https://publications.waset.org/abstracts/36346/a-ratiometric-inorganic-phosphate-sensor-based-on-cdsezns-qds-and-rhodamine-6g-doped-nanofibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36346.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">409</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">128</span> Removal of Deposits and Improvement of Shelf Life in CO₂-Rich Mineral Water by Ozone-Microbubbles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Un%20Hwa%20Choe">Un Hwa Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Hyon%20Choe"> Jong Hyon Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Jun%20Kim"> Yong Jun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to effectively remove Fe2+ by using ozone microbubbles in bottled mineral water to prevent sediment from occurring during storage and increase shelf life. By considering the characteristics of mineral water with low solubility of ozone and high CO2 content, a suitable ozone injection step was chosen and a new mineral water treatment method using microbubbles was proposed. As a result of the treatment of the bottled mineral water with ozone microbubbles, the iron ion concentration was reduced from 0.14 mg/L to 0.01 mg/L, and the shelf life increased to 360 days. During the treatment, the concentrations of K+ and Na+ were almost unchanged, and the deposition time was reduced to one-third compared to the natural oxidation. <p
