</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">437</span> A Comparison between the McGrath Video Laryngoscope and the Macintosh Laryngoscopy in Children with Expected Normal Airway</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=Ji%20Eun%20Kim"> Ji Eun Kim</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: This prospective, randomized, controlled study was performed to evaluate the usefulness of the McGrath VL compared to Macintosh laryngoscopy in children with expected normal airway during endotracheal intubation, by comparing the time to intubation and ease of intubation. Methods: Eighty-four patients, aged 1-10 years undergoing endotracheal intubation for elective surgery were randomly assigned to McGrath group (n = 42) or Macintosh group (n = 42). Anesthesia was induced with propofol 2.5-3.0 mg/kg and sevoflurane 5-8 vol%. Orotracheal intubation was performed 2 minutes after injection of rocuronium 0.6 mg/kg with McGrath VL or Macintosh laryngoscope. The primary outcome was time to intubation. The Cormack and Lehane glottic grade, intubation difficulty score (IDS), and success rate of intubation were assessed. Hemodynamic changes also were recorded. Results: Median time to intubation [interquartile range] was not different between the McGrath group and the Macintosh group (25.0 [22.8-28.3] s vs. 26.0 [24.0-29.0] s, p = 0.301). The incidence of grade I glottic view was significantly higher in theMcGrath group than in the Macintosh group (95% vs. 74%, p = 0.013). Median IDS was lower in the McGrath group than in the Macintosh group (0 [0-0] vs. 0 [0-1], p = 0.018). There were no significant differences in success rate on intubation or hemodynamics between the two groups. Conclusions: McGrath VL provides better laryngeal views and lower IDS, but similar intubation times and success rates compared to the Macintosh laryngoscope in children with the normal airway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intubation" title="intubation">intubation</a>, <a href="https://publications.waset.org/abstracts/search?q=Macintosh%20laryngoscopy" title=" Macintosh laryngoscopy"> Macintosh laryngoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mcgrath%20videolaryngoscopy" title=" Mcgrath videolaryngoscopy"> Mcgrath videolaryngoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a> </p> <a href="https://publications.waset.org/abstracts/75537/a-comparison-between-the-mcgrath-video-laryngoscope-and-the-macintosh-laryngoscopy-in-children-with-expected-normal-airway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75537.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">228</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">436</span> Optimal Rotor Design of an 150kW-Class IPMSM through the 3D Voltage-Inductance Map Analysis Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eung-Seok%20Park">Eung-Seok Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Chul%20Jeong"> Tae-Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jong%20Park"> Hyun-Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jun"> Hyun-Woo Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Woo%20Kang"> Dong-Woo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presents a methodology to determine detail design directions of an 150kW-class IPMSM (interior permanent magnet synchronous motor) and its detail design.

The upconversion emission spectra in 1 mol% Er³⁺/5 mol% Yb³⁺/xTm³ tri-doped Y₂O₃ nanophosphors sintered at 1000 °C with x from 0 to 0.5 mol%. The blue emission intensity increase with Tm³⁺ concentration from 0 to 0.5 mol%, it is due to the 2F7/2→2F5/2 transition of Yb³⁺ around 10,000 cm-1 could easily reach the Tm³⁺ sates. The white light is composed with the blue (1G4→3H6 of Tm³⁺), green (2H11/2, 4S3/2→4I15/2 of Er³⁺), and red (4F9/2→4I15/2 of Er³⁺) upconversion radiations. The Y₂O₃: Er³⁺/Yb³⁺/Tm³⁺ nanophosphors show from white to green upconversion emission at power of 600 mW/cm² as sintering temperature increased.

The aim of this study was to compare tracheal intubation performance regarding the time to intubation, glottic view, difficulty, and dental click, by a novice using McGrath VL, Pentax Airway Scope (AWS) and Macintosh laryngoscope in normal and cervical immobilized manikin models. Methods: Thirty-five anesthesia nurses without previous intubation experience were recruited. The participants performed endotracheal intubation in a manikin model at two simulated neck positions (normal and fixed neck via cervical immobilization), using three different devices (McGrath VL, Pentax AWS, and Macintosh direct laryngoscope) at three times each. Performance parameters included intubation time, success rate of intubation, Cormack Lehane laryngoscope grading, dental click, and subjective difficulty score. Results: Intubation time and success rate at the first attempt were not significantly different between the 3 groups in normal airway manikin. In the cervical immobilized manikin, the intubation time was shorter (p = 0.012) and the success rate with the first attempt was significantly higher (p < 0.001) when using McGrath VL and Pentax AWS compared with Macintosh laryngoscope. Both VLs showed less difficulty score (p < 0.001) and more Cormack Lehane grade I (p < 0.001). The incidence of dental clicks was higher with McGrath VL than Macintosh laryngoscope in the normal and cervical immobilized airway (p = 0.005, p < 0.001, respectively). Conclusion: McGrath VL and Pentax AWS resulted in shorter intubation time, higher first attempt success rate, compared with Macintosh laryngoscope by a novice intubator in a cervical immobilized manikin model. McGrath VL could be reduced the risk of dental injury compared with Macintosh laryngoscope in this scenario. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intubation" title="intubation">intubation</a>, <a href="https://publications.waset.org/abstracts/search?q=manikin" title=" manikin"> manikin</a>, <a href="https://publications.waset.org/abstracts/search?q=novice" title=" novice"> novice</a>, <a href="https://publications.waset.org/abstracts/search?q=videolaryngoscope" title=" videolaryngoscope"> videolaryngoscope</a> </p> <a href="https://publications.waset.org/abstracts/97770/comparison-of-mcgrath-pentax-and-macintosh-laryngoscope-in-normal-and-cervical-immobilized-manikin-by-novices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97770.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">158</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">432</span> Biomimetic Adhesive Pads for Precision Manufacturing Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoon%20Yi">Hoon Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Minho%20Sung"> Minho Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hangil%20Ko"> Hangil Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Moon%20Kyu%20Kwak"> Moon Kyu Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoon%20Eui%20Jeong"> Hoon Eui Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inspired by the remarkable adhesion properties of gecko lizards, bio-inspired dry adhesives with smart adhesion properties have been developed in the last decade. Compared to earlier dry adhesives, the recently developed ones exhibit excellent adhesion strength, smart directional adhesion, and structural robustness. With these unique adhesion properties, bio-inspired dry adhesive pads have strong potential for use in precision industries such as semiconductor or display manufacturing. In this communication, we present a new manufacturing technology based on advanced dry adhesive systems that enable precise manipulation of large-area substrates over repeating cycles without any requirement for external force application. This new manufacturing technique is also highly accurate and environment-friendly, and thus has strong potential as a next-generation clean manufacturing technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gecko" title="gecko">gecko</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20robot" title=" manufacturing robot"> manufacturing robot</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20manufacturing" title=" precision manufacturing"> precision manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/38058/biomimetic-adhesive-pads-for-precision-manufacturing-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38058.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">505</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">431</span> Caring and Sustainable Government: An Examination of Political Vision of Jeong Do-Jeon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeon%20Sop%20Baek">Hyeon Sop Baek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper will briefly investigate Jeong Do-jeon’s political philosophy. Jeong Do-jeon was a Korean Confucian philosopher and politician during the turbulent 14th Century who revolted against the old order, founded Joseon Dynasty, and significantly impacted the development of Korean culture. Jeong’s vision of an ideal state involved a polity that has its roots in the people -that is, an ideal government prioritizes caring for the welfare of the people, respecting and attending to the diverse opinions and concerns of the people, and relies on the genuine, voluntary support of the people. With the neo-Confucian worldview in mind -that every human being has the equal potential to become a moral person- Jeong sought to create a world suitable for everybody to contribute to the decision-making procedure and be able to realize their potential fully. This paper will first examine his works and present a quick overview of his vision of the ideal government. Then, it will examine the Confucian virtues of ren (仁) and yi (義) and how they formulate the basis of his philosophy, and then discuss the central features of his vision of government: popular mandate, equity of wealth, promoting freedom of expression and political participation, and elevating caring disposition as the paramount quality of the political leaders. Furthermore, this paper aims to analyze the element of care inherent within his political philosophy, namely his view on the dynamics of power, nurturing the people, and noncoercive justice. Finally, a discussion on why his philosophy is still relevant in the contemporary context will be provided. Jeong’s view aimed at building a sustainable model of government, by proposing that the people should be the foundation of a state and that they need to be carefully nurtured so they can realize their inborn potential and continue to contribute to the sustenance of the world, is the focal point of Jeong’s philosophy. Just as he sought to rebuild his world following the turmoils of the 14th Century, his philosophy still has a substantial implication on how we should strive to rebuild our society today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Korea" title="Korea">Korea</a>, <a href="https://publications.waset.org/abstracts/search?q=Confucianism" title=" Confucianism"> Confucianism</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Do-jeon" title=" Jeong Do-jeon"> Jeong Do-jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseon" title=" Joseon"> Joseon</a>, <a href="https://publications.waset.org/abstracts/search?q=Korean%20philosophy" title=" Korean philosophy"> Korean philosophy</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20philosophy" title=" political philosophy"> political philosophy</a> </p> <a href="https://publications.waset.org/abstracts/159524/caring-and-sustainable-government-an-examination-of-political-vision-of-jeong-do-jeon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159524.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">430</span> Indoor Temperature Estimation with FIR Filter Using R-C Network Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung%20Hyun%20You">Sung Hyun You</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Hoon%20Kim"> Jeong Hoon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Ki%20Kim"> Dae Ki Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon%20Ki%20Ahn"> Choon Ki Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we proposed a new strategy for estimating indoor temperature based on the modified resistance capacitance (R–C) network thermal dynamic model.

Their widespread detection and accumulation in the environment raise concerns about whether these chemicals might be developmental toxicants and teratogens in the ecosystem. We evaluated and compared the toxicity of PFCs of containing various numbers of carbon atoms (C8-11 carbons) on vertebrate embryogenesis. We assessed the developmental toxicity and teratogenicity of various PFCs. The toxic effects on Xenopus embryos were evaluated using different methods. We measured teratogenic indices (TIs) and investigated the mechanisms underlying developmental toxicity and teratogenicity by measuring the expression of organ-specific biomarkers such as xPTB (liver), Nkx2.5 (heart), and Cyl18 (intestine). All PFCs that we tested were found to be developmental toxicants and teratogens. Their toxic effects were strengthened with increasing length of the fluorinated carbon chain. Furthermore, we produced evidence showing that perfluorodecanoic acid (PFDA) and perfluoroundecanoic acid (PFuDA) are more potent developmental toxicants and teratogens in an animal model compared to the other PFCs we evaluated [perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA)]. In particular, severe defects resulting from PFDA and PFuDA exposure were observed in the liver and heart, respectively, using the whole mount in situ hybridization, real-time PCR, pathologic analysis of the heart, and dissection of the liver. Our studies suggest that most PFCs are developmental toxicants and teratogens, however, compounds that have higher numbers of carbons (i.e., PFDA and PFuDA) exert more potent effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PFC" title="PFC">PFC</a>, <a href="https://publications.waset.org/abstracts/search?q=xenopus" title=" xenopus"> xenopus</a>, <a href="https://publications.waset.org/abstracts/search?q=fetax" title=" fetax"> fetax</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a> </p> <a href="https://publications.waset.org/abstracts/46966/evaluation-of-developmental-toxicity-and-teratogenicity-of-perfluoroalkyl-compounds-using-fetax" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46966.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">427</span> ELectromagnetic-Thermal Coupled Analysis of PMSM with Cooling Channel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jun">Hyun-Woo Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Chul%20Jeong"> Tae-Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Huai-Cong%20Liu"> Huai-Cong Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents the electromagnetic-thermal flow coupled analysis of permanent magnet synchronous motor (PMSM) which has cooling channel in stator core for forced air cooling.

The X-ray generator was designed using the MCNPX code, and the X-ray absorption spectrum of the semiconductor device was obtained based on the designed X-ray generator code. To evaluate the utility of the filter, the X-ray absorption rates of the semiconductor device were calculated and compared for Ag, Rh, Mo and V filters with thicknesses of 25μm, 50μm, and 75μm. The results showed that the X-ray absorption rate varied with the type and thickness of the filter, ranging from 8.74% to 49.28%. The Rh filter showed the highest X-ray absorption rates of 29.8%, 15.18% and 8.74% for the above-mentioned filter thicknesses. As shown above, the characteristics of the X-ray absorption with respect to the type and thickness of the filter were identified using MCNPX simulation. With these results, both time and expense could be saved in the production of the desired filter. In the future, this filter will be produced, and its performance will be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-ray" title="X-ray">X-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNPX" title=" MCNPX"> MCNPX</a>, <a href="https://publications.waset.org/abstracts/search?q=filter" title=" filter"> filter</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor" title=" semiconductor"> semiconductor</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a> </p> <a href="https://publications.waset.org/abstracts/53350/study-on-filter-for-semiconductor-of-minimizing-damage-by-x-ray-laminography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53350.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">423</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">422</span> Effect of Pre-Construction on Construction Schedule and Client Loyalty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong%20Hoon%20Kim">Jong Hoon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Soo%20Lee"> Hyun-Soo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Moonseo%20Park"> Moonseo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Jeong"> Min Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Inbeom%20Lee"> Inbeom Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pre-construction is essential in achieving the success of a construction project. Due to the early involvement of project participants in the construction phase, project managers are able to plan ahead and solve issues well in advance leading to the success of the project and the satisfaction of the client. This research utilizes quantitative data derived from construction management projects in order to identify the relationship between pre-construction, construction schedule, and client satisfaction. A total of 65 construction projects and 93 clients were investigated for this research in an attempt to identify (a) the relationship between pre-construction and schedule reduction, and (b) pre-construction and client loyalty. Based on the quantitative analysis, this research was able to establish a negative correlation based on 65 construction projects between pre-construction and project schedule existed. This finding represents that the more pre-construction is performed for a certain project, the overall construction schedule decreased. Then, to determine the relationship between pre-construction and client satisfaction, Net Promoter Score (NPS) of 93 clients from the 65 projects was utilized. Pre-construction and NPS was further analyzed and a positive correlation was found between the two. This infers that clients tend to be more satisfied with projects with higher ratio of pre-construction than those projects with less pre-construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=client%20loyalty" title="client loyalty">client loyalty</a>, <a href="https://publications.waset.org/abstracts/search?q=NPS" title=" NPS"> NPS</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-construction" title=" pre-construction"> pre-construction</a>, <a href="https://publications.waset.org/abstracts/search?q=schedule%20reduction" title=" schedule reduction"> schedule reduction</a> </p> <a href="https://publications.waset.org/abstracts/48581/effect-of-pre-construction-on-construction-schedule-and-client-loyalty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48581.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">360</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">421</span> A Different Approach to Optimize Fuzzy Membership Functions with Extended FIR Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Ho%20Chung">Jun-Ho Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Hyun%20Yoo"> Sung-Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Hwan%20Choi"> In-Hwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kook%20Lee"> Hyun-Kook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Moon-Kyu%20Song"> Moon-Kyu Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon-Ki%20Ahn"> Choon-Ki Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extended finite impulse response (EFIR) filter is addressed to optimize membership functions (MFs) of the fuzzy model that has strong nonlinearity.

Although there are various technologies available to detect and monitor radioactive substances in the air, the technologies to detect underwater radioactive substances are scarce. In this study, computer simulation of the underwater detection system measuring beta-ray, a radioactive substance, has been done through MCNP. CaF₂, YAP(Ce) and YAG(Ce) have been used in the computer simulation to detect beta-ray as scintillator. Also, the source used in the computer simulation is Sr-90 and Y-90, both of them emitting only pure beta-ray. The distance between the source and the detector was shifted from 1mm to 10mm by 1 mm in the computer simulation. The result indicated that Sr-90 was impossible to measure below 1 mm since its emission energy is low while Y-90 was able to be measured up to 10mm underwater. In addition, the detector designed with CaF₂ had the highest efficiency among 3 scintillators used in the computer simulation. Since it was possible to verify the detectable range and the detection efficiency according to modeling through MCNP simulation, it is expected that such result will reduce the time and cost in building the actual beta-ray detector and evaluating its performances, thereby contributing the research and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beta-ray" title="Beta-ray">Beta-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=CaF%E2%82%82" title=" CaF₂"> CaF₂</a>, <a href="https://publications.waset.org/abstracts/search?q=detector" title=" detector"> detector</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNP%20simulation" title=" MCNP simulation"> MCNP simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=scintillator" title=" scintillator"> scintillator</a> </p> <a href="https://publications.waset.org/abstracts/53352/study-on-beta-ray-detection-system-in-water-using-a-mcnp-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53352.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">510</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">419</span> Fused Salt Electrolysis of Rare-Earth Materials from the Domestic Ore and Preparation of Rare-Earth Hydrogen Storage Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeong-Hyun%20Yoo">Jeong-Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanjung%20Kwon"> Hanjung Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Wook%20Cho"> Sung-Wook Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fused salt electrolysis was studied to make the high purity rare-earth metals using domestic rare-earth ore.

La1-xSrxCo1-yFeyO3, which is an air electrode, is occurred stability degradations due to reaction and delamination with yittria stabilized zirconia(YSZ) electrolyte in a water electrolysis mode. To complement this phenomenon SOCs need gadolinium doped ceria(GDC) buffer layer between electrolyte and air electrode. However, GDC buffer layer requires a high sintering temperature and it causes a reaction with YSZ electrolyte. This study carried out low temperature sintering of GDC layer by applying Cu-oxide as a sintering aid. The effect of a copper additive as a sintering aid to lower the sintering temperature for the construction of solid oxide fuel cells (SOFCs) was investigated. GDC buffer layer with 0.25-10 mol% CuO sintering aid was prepared by reacting GDC power and copper nitrate solution followed by heating at 600 ℃. The sintering of CuO-added GDC powder was optimized by investigating linear shrinkage, microstructure, grain size, ionic conductivity, and activation energy of CuO-GDC electrolytes at temperatures ranging from 1100 to 1400 ℃. The sintering temperature of the CuO-GDC electrolyte decreases from 1400 ℃ to 1100 ℃ by adding the CuO sintering aid. The ionic conductivity of the CuO-GDC electrolyte shows a maximum value at 0.5 mol% of CuO. However, the addition of CuO has no significant effects on the activation energy of GDC electrolyte.

Astrocytes are the most common supporting cells and play roles in metabolism between neurons and blood vessel. For this function, engineered astrocytes have been studied as a therapeutic source for CNS injury. In neural tissue engineering, nanofiber has been suggested as an effective scaffold for providing structure and mechanical properties influencing physiology. Cellulose acetate (CA) has been investigated for material to fabricate scaffold because of its biocompatibility, biodegradability and fine thermal stability. In this research, CA nanofiber was modified via heat treatment and its effect on astrocyte activity was evaluated. Adhesion and viability of astrocyte were increased in proportion to stiffness. Additionally, expression of GFAP, a marker of astrocyte activation, was increased via stiffness of scaffold. This research suggests a simple modification method to change stiffness of CA nanofiber and shows cellular behavior affecting stiffness of three-dimensional scaffold independently.

Tram-Train is a Tram and Train-combined railway vehicles, which operates at a maximum speed of 70km/h in the city section (Tram section) and at a maximum speed of 150km/h in the out-of-city section (Train section). For this reason, tram-train was designed to be an IPMSM (Interior Permanent Synchronous Motor) with a wide range of speed variation. IPMSM’s magnetic path varies depending on the shape of rotor and in this case, the power characteristics are different in the constant torque area and the flux weakening area. Therefore, this study suggests a method to improve Tram-Train’s traction force, based on the relationship between magnetic torque and reluctance torque. The suggested method was applied through IPMSM rotor shape design and electromagnetic field finite element method was conducted to verify the validity of the suggested method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tram-train" title="tram-train">tram-train</a>, <a href="https://publications.waset.org/abstracts/search?q=traction%20motor" title=" traction motor"> traction motor</a>, <a href="https://publications.waset.org/abstracts/search?q=IPMSM" title=" IPMSM"> IPMSM</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous%20motor" title=" synchronous motor"> synchronous motor</a>, <a href="https://publications.waset.org/abstracts/search?q=railway%20vehicles" title=" railway vehicles"> railway vehicles</a> </p> <a href="https://publications.waset.org/abstracts/41383/a-study-on-traction-motor-design-for-obtaining-the-maximum-traction-force-of-tram-train" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41383.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">471</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">415</span> Change of Flavor Characteristics of Flavor Oil Made Using Sarcodon aspratus (Sarcodon aspratus Berk.

The UC efficiency is mainly dependent on the host lattice and the interaction between the host lattice and doped ions. Up to date, various host matrices, such as oxides, fluorides, vanadates and phosphates, have been investigated as efficient UC luminescent hosts. Recently, oxide materials with low phonon energy have been investigated as the host matrices of UC materials due to their high chemical durability and physical stability. A series of Sr2CeO4: Tm3+/Yb3+ phosphors with different concentrations of Yb3+ ions have been successfully prepared using the high-energy ball milling method. In this study, we reported the UC luminescent properties of Tm3+/Yb3+ ions co-doped Sr2CeO4 phosphors under an excitation wavelength of 975 nm. Furthermore, the structural and morphological characteristics, as well as the UC luminescence mechanism were investigated in detail. The X-ray diffraction patterns confirmed their orthorhombic structure. Under 975 nm excitation, the emission peaks were observed at 478 nm (blue) and 652 nm (red), corresponding to the 1G4 → 3H6 and 1G4 → 3F4 transitions of Tm3+, respectively.

The proposed scheme considers the location of a user and applies the suitable cooperative scheme. In cellular systems, the performance of communication is degraded if the user is located in the cell edge. In conventional scheme, two base stations are used in order to obtain diversity gain. However, the performance of communication is not sufficiently improved since the distance between each base station and a user is still distant. Therefore, we propose a scheme that the relays are used and the cooperative scheme is adaptively applied according to the user location. Through simulation results, it is confirmed that the proposed scheme has better performance than the conventional scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20transmission" title="adaptive transmission">adaptive transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperative%20communication" title=" cooperative communication"> cooperative communication</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity%20gain" title=" diversity gain"> diversity gain</a>, <a href="https://publications.waset.org/abstracts/search?q=OFDM" title=" OFDM"> OFDM</a> </p> <a href="https://publications.waset.org/abstracts/32518/adaptive-cooperative-scheme-considering-the-user-location" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32518.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">572</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">412</span> EEG-Based Classification of Psychiatric Disorders: Bipolar Mood Disorder vs. Schizophrenia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han-Jeong%20Hwang">Han-Jeong Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hyun%20Jo"> Jae-Hyun Jo</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Alimardani"> Fatemeh Alimardani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An accurate diagnosis of psychiatric diseases is a challenging issue, in particular when distinct symptoms for different diseases are overlapped, such as delusions appeared in bipolar mood disorder (BMD) and schizophrenia (SCH). In the present study, we propose a useful way to discriminate BMD and SCH using electroencephalography (EEG). A total of thirty BMD and SCH patients (15 vs. 15) took part in our experiment. EEG signals were measured with nineteen electrodes attached on the scalp using the international 10-20 system, while they were exposed to a visual stimulus flickering at 16 Hz for 95 s. The flickering visual stimulus induces a certain brain signal, known as steady-state visual evoked potential (SSVEP), which is differently observed in patients with BMD and SCH, respectively, in terms of SSVEP amplitude because they process the same visual information in own unique way. For classifying BDM and SCH patients, machine learning technique was employed in which leave-one-out-cross validation was performed. The SSVEPs induced at the fundamental (16 Hz) and second harmonic (32 Hz) stimulation frequencies were extracted using fast Fourier transformation (FFT), and they were used as features. The most discriminative feature was selected using the Fisher score, and support vector machine (SVM) was used as a classifier. From the analysis, we could obtain a classification accuracy of 83.33 %, showing the feasibility of discriminating patients with BMD and SCH using EEG. We expect that our approach can be utilized for psychiatrists to more accurately diagnose the psychiatric disorders, BMD and SCH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar%20mood%20disorder" title="bipolar mood disorder">bipolar mood disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=electroencephalography" title=" electroencephalography"> electroencephalography</a>, <a href="https://publications.waset.org/abstracts/search?q=schizophrenia" title=" schizophrenia"> schizophrenia</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/60167/eeg-based-classification-of-psychiatric-disorders-bipolar-mood-disorder-vs-schizophrenia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60167.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">421</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">411</span> Drag Reduction of Base Bleed at Various Flight Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Man%20Chul%20Jeong">Man Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung%20Jin%20Lee"> Hyoung Jin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Yoon%20Lee"> Sang Yoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Hyun%20Park"> Ji Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Wook%20Chang"> Min Wook Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Seuck%20Jeung"> In-Seuck Jeung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focus on the drag reduction effect of the base bleed at supersonic flow. Base bleed is the method which bleeds the gas on the tail of the flight vehicle and reduces the base drag, which occupies over 50% of the total drag in any flight speed. Thus base bleed can reduce the total drag significantly, and enhance the total flight range. Drag reduction ratio of the base bleed is strongly related to the mass flow rate of the bleeding gas. Thus selecting appropriate mass flow rate is important. However, since the flight vehicle has various flight speed, same mass flow rate of the base bleed can have different drag reduction effect during the flight. Thus, this study investigates the effect of the drag reduction depending on the flight speed by numerical analysis using STAR-CCM+. The analysis model is 155mm diameter projectile with boat-tailed shape base. Angle of the boat-tail is chosen previously for minimum drag coefficient. Numerical analysis is conducted for Mach 2 and Mach 3, with various mass flow rate, or the injection parameter I, of the bleeding gas and the temperature of the bleeding gas, is fixed to 300K. The results showed that I=0.025 has the minimum drag at Mach 2, and I=0.014 has the minimum drag at Mach 3. Thus as the Mach number is higher, the lower mass flow rate of the base bleed has more effect on drag reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20bleed" title="base bleed">base bleed</a>, <a href="https://publications.waset.org/abstracts/search?q=supersonic" title=" supersonic"> supersonic</a>, <a href="https://publications.waset.org/abstracts/search?q=drag%20reduction" title=" drag reduction"> drag reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=recirculation" title=" recirculation"> recirculation</a> </p> <a href="https://publications.waset.org/abstracts/69358/drag-reduction-of-base-bleed-at-various-flight-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">410</span> Approach to Functional Safety-Compliant Design of Electric Power Steering Systems for Commercial Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Chul%20Koag">Hyun Chul Koag</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Sik%20Ahn"> Hyun-Sik Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose a design approach for the safety mechanism of an actuator used in a commercial vehicle’s EPS system. As the number of electric/electronic system in a vehicle increases, the importance of the functional safety has been receiving much attention. EPS(Electric Power Steering) systems for commercial vehicles require large power than passenger vehicles, and hence, dual motor can be applied to get more torque. We show how to formulate the development process for the design of hardware and software of an EPS system using dual motors. A lot of safety mechanisms for the processor, sensors, and memory have been suggested, however, those for actuators have not been fully researched. It is shown by metric analyses that the target ASIL(Automotive Safety Integrated Level) is satisfied in the point of view of hardware of EPS controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safety%20mechanism" title="safety mechanism">safety mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20safety" title=" functional safety"> functional safety</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20vehicles" title=" commercial vehicles"> commercial vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20power%20steering" title=" electric power steering"> electric power steering</a> </p> <a href="https://publications.waset.org/abstracts/71842/approach-to-functional-safety-compliant-design-of-electric-power-steering-systems-for-commercial-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71842.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">393</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">409</span> Anti-Inflammatory Effect of Myristic Acid through Inhibiting NF-κB and MAPK Signaling Pathways in Lipopolysaccharide-Stimulated RAW 264.7 Macrophage Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Ji%20Hyun">Hyun Ji Hyun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo%20Sun%20Suh"> Hyo Sun Suh</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Kook%20Kim"> Min Kook Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Chan%20Kwon"> Yong Chan Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung-Mu%20Lee"> Byung-Mu Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scope: This study is focused on the effect of myristic acid on LPS-induced inflammation in RAW 264.7 macrophage cells. Methods and results: For the experiment, RAW 264.7 mouse macrophage cell line was used. Results showed that treatment with myristic acid can attenuate LPS-induced inflammation. Moreover, myristic acid significantly suppressed expression of inflammatory mediators and down-regulating UVB-induced intracellular ROS generation. Furthermore, myristic acid reduced the expression of NF-κB by inhibiting degradation of IκB-α and ERK, JNK, and p38 pathways by inhibiting phosphorylation in RAW 264.7 macrophage cells. Conclusion: Overall, these data suggest that the myristic acid could reduce LPS-induced inflammation.
