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">199</span> Improving Cheon-Kim-Kim-Song (CKKS) Performance with Vector Computation and GPU Acceleration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smaran%20Manchala">Smaran Manchala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Homomorphic Encryption (HE) enables computations on encrypted data without requiring decryption, mitigating data vulnerability during processing. Usable Fully Homomorphic Encryption (FHE) could revolutionize secure data operations across cloud computing, AI training, and healthcare, providing both privacy and functionality, however, the computational inefficiency of schemes like Cheon-Kim-Kim-Song (CKKS) hinders their widespread practical use. This study focuses on optimizing CKKS for faster matrix operations through the implementation of vector computation parallelization and GPU acceleration. The variable effects of vector parallelization on GPUs were explored, recognizing that while parallelization typically accelerates operations, it could introduce overhead that results in slower runtimes, especially in smaller, less computationally demanding operations. To assess performance, two neural network models, MLPN and CNN—were tested on the MNIST dataset using both ARM and x86-64 architectures, with CNN chosen for its higher computational demands. Each test was repeated 1,000 times, and outliers were removed via Z-score analysis to measure the effect of vector parallelization on CKKS performance. Model accuracy was also evaluated under CKKS encryption to ensure optimizations did not compromise results. According to the results of the trail runs, applying vector parallelization had a 2.63X efficiency increase overall with a 1.83X performance increase for x86-64 over ARM architecture. Overall, these results suggest that the application of vector parallelization in tandem with GPU acceleration significantly improves the efficiency of CKKS even while accounting for vector parallelization overhead, providing impact in future zero trust operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CKKS%20scheme" title="CKKS scheme">CKKS scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=runtime%20efficiency" title=" runtime efficiency"> runtime efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=fully%20homomorphic%20encryption%20%28FHE%29" title=" fully homomorphic encryption (FHE)"> fully homomorphic encryption (FHE)</a>, <a href="https://publications.waset.org/abstracts/search?q=GPU%20acceleration" title=" GPU acceleration"> GPU acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20parallelization" title=" vector parallelization"> vector parallelization</a> </p> <a href="https://publications.waset.org/abstracts/192456/improving-cheon-kim-kim-song-ckks-performance-with-vector-computation-and-gpu-acceleration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192456.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">23</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">198</span> Ripening Conditions Suitable for Marketing of Winter Squash ‘Bochang’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Do%20Su%20Park">Do Su Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Jun%20Park"> Sang Jun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheon%20Soon%20Jeong"> Cheon Soon Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was performed in order to investigate the optimum ripening conditions for the marketing of Squash. Research sample 'Bochang' was grown at Hongcheonin in Gangwon province in August 2014. Ripening the samples were stored under the conditions of 25℃, 30℃, and 35℃ with the humidity RH70 ± 5%. They were checked every 3 days for 21 days. The respiration rate, water loss, hardness, coloration, the contents of soluble solids, starch, total sugar were evaluated after storage. Respiration rate was reduced in all treatments with longer storage period. Water loss was increased in the higher temperature. The 13% water loss was found at 35℃ on 21st storage day. The store initially 25℃ and 30℃ Hardness 47N and the ripening 21 days decreased slightly. On the other hand, in the case of 35℃ showed a large reduction than 25℃ and 30℃. Soluble solid contents were increased with longer ripening period. 30℃ and 35℃ was highest ripening 15 days. In the case of 25℃, it was highest on 21th day. The higher the temperature, the higher the soluble solids content are. 25℃ and 30℃ Coloration was increased rapidly until the ripening 12 days. In case of 35℃, continued increase up to 21 days. 25℃ and 30℃ showed no differences. Meanwhile, in case of 35℃, appearance quality was reduced in Occurrence of yellowing phenomenon of pericarp occurs from after ripening for 9 days. The coloration of fruit flesh is increase until after ripening for 9 days and decrease from after ripening for 9 days. There was no significant difference depending on the conditions of temperature. The higher the temperature, the lower the content of the starch. In case of 30℃ and 35℃, was reduced with longer storage period. 25℃ was minimal content change. Total sugar was increased in all treatments with longer storage period. The higher the temperature, the higher the amount of total sugar content is. Therefore, at 25℃ for 18-21 days and at 30℃ for 12-15 days is suitable for ripening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marketing" title="marketing">marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=ripening" title=" ripening"> ripening</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=winter%20squash" title=" winter squash "> winter squash </a> </p> <a href="https://publications.waset.org/abstracts/20818/ripening-conditions-suitable-for-marketing-of-winter-squash-bochang" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20818.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">598</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">197</span> Structural Analysis of Multi-Pressure Integrated Vessel for Sport-Multi-Artificial Environment System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joon-Ho%20Lee">Joon-Ho Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-Hwan%20Yoon"> Jeong-Hwan Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Hwan%20Yoon"> Jung-Hwan Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangmo%20Kang"> Sangmo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-Yeon%20Hong"> Su-Yeon Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jeong"> Hyun-Woo Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaeick%20Chae"> Jaeick Chae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are several dedicated individual chambers for sports that are supplied and used, but none of them are multi-pressured all-in-one chambers that can provide a sports multi-environment simultaneously.

PV Generation System on the ground applied considerably until now raise environmental damage by using farmland and forest land, PV generation system on the building roof is already installed at almost the whole place of business and additional installation is almost impossible. Installation space of PV generation system is infinite and efficient national land use is possible because it is installed above water. Also, PV module's efficiency increase by natural water cooling method and no shade. So it is identified that annual power generation is more than PV generation system on the ground by operating performance data. Although it is difficult to design and construct by high cost, little application case, difficult installation of floater, mooring device, underwater cable, etc. However, it has been examined cost reduction plan such as structure weight lightening, floater optimal design, etc. This thesis described basic and working design result systematically about K-water's floating PV generation system development and suggested optimal design method of floating PV generation system. Main contents are photovoltaic array location select, substation location select related underwater cable, PV module and inverter design, transmission and substation equipment design, floater design related structure weight lightening, mooring system design related water level fluctuation, grid connecting technical review, remote control and monitor equipment design, etc. This thesis will contribute to optimal design and business extension of floating PV generation system, and it will be opportunity revitalize clean energy development using water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PV%20generation%20system" title="PV generation system">PV generation system</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title=" clean energy"> clean energy</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20growth" title=" green growth"> green growth</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/48114/application-case-and-result-consideration-about-basic-and-working-design-of-floating-pv-generation-system-installed-in-the-upstream-of-dam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48114.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">413</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">195</span> Artificial Intelligence Based Abnormality Detection System and Real Valuᵀᴹ Product Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junbeom%20Lee">Junbeom Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaehyuck%20Cho"> Jaehyuck Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Wookyeong%20Jeong"> Wookyeong Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonghan%20Won"> Jonghan Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungmin%20Hwang"> Jungmin Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Youngseok%20Song"> Youngseok Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Taikyeong%20Jeong"> Taikyeong Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates and analyzes meta-learning technologies that use multiple-cameras to monitor and check abnormal behavior in people in real-time in the area of healthcare fields. Advances in artificial intelligence and computer vision technologies have confirmed that cameras can be useful for individual health monitoring and abnormal behavior detection. Through this, it is possible to establish a system that can respond early by automatically detecting abnormal behavior of the elderly, such as patients and the elderly. In this paper, we use a technique called meta-learning to analyze image data collected from cameras and develop a commercial product to determine abnormal behavior. Meta-learning applies machine learning algorithms to help systems learn and adapt quickly to new real data. Through this, the accuracy and reliability of the abnormal behavior discrimination system can be improved. In addition, this study proposes a meta-learning-based abnormal behavior detection system that includes steps such as data collection and preprocessing, feature extraction and selection, and classification model development. Various healthcare scenarios and experiments analyze the performance of the proposed system and demonstrate excellence compared to other existing methods. Through this study, we present the possibility that camera-based meta-learning technology can be useful for monitoring and testing abnormal behavior in the healthcare area. <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=abnormal%20behavior" title=" abnormal behavior"> abnormal behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20detection" title=" early detection"> early detection</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20monitoring" title=" health monitoring"> health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/168915/artificial-intelligence-based-abnormality-detection-system-and-real-valu-product-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168915.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">87</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">194</span> Identity and Disability in Contemporary East Asian Dance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanghyun%20Park">Sanghyun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Influenced by the ideas of collectivism, East Asian contemporary dance is marked by an emphasis on unity and synchronization. A growing element of this discipline that disrupts the path that strives to attain perfection, requiring coordination between multiple parties in order to produce work of their highest artistic potential, with the support from individuals or groups is the presence of disabled dancers. Kawanaka Yo, a Japanese dancer with a mental disability, argues through her '“Dance of Peace' that a dancer should focus on her impulses and natural thoughts through improvisational dancing and eschewal of documentation. Professor and poet Jung-Gyu Jeong, co-founder of the Korea Disability International Art Company, demonstrates with his company’s modernized performances of popular works and musicals that disabled artists do not need perfection so long as they can assert their finesse to mimic or create an equivalence with able-bodied dancers. Yo has studied various forms of modern dance and ballet in Japan and has used her training to ease her mental disability but also accept her handicap as an extension of her identity, representing a trend in disabled dance that favors individuality and acceptance. In contrast, Jeong is an influential figure in South Korea for disabled dancers and artists, believing that disabled artists must overcome a certain threshold in order to reach a status as an artist that is equivalent to a 'normal artist.' East Asian art created by the disabled should not be judged according to different criteria or rubrics compared to able-bodied artists because, as Yo explains, a person’s identity and her handicaps characterize the meaning of, and the value of, the piece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disability%20studies" title="disability studies">disability studies</a>, <a href="https://publications.waset.org/abstracts/search?q=modern%20dance" title=" modern dance"> modern dance</a>, <a href="https://publications.waset.org/abstracts/search?q=East%20Asia" title=" East Asia"> East Asia</a>, <a href="https://publications.waset.org/abstracts/search?q=politics%20of%20identity" title=" politics of identity"> politics of identity</a> </p> <a href="https://publications.waset.org/abstracts/82109/identity-and-disability-in-contemporary-east-asian-dance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82109.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">209</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">193</span> Thermal Pre-Treatment of Sewage Sludge in Fluidized Bed for Enhancing Its Solid Fuel Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sujeeta%20Karki">Sujeeta Karki</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeeban%20Poudel"> Jeeban Poudel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ja%20Hyung%20Choi"> Ja Hyung Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sea%20Cheon%20Oh"> Sea Cheon Oh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A lab-scale fluidized bed was used for the study of sewage sludge, a non-lignocellulosic biomass, torrefaction. The influence of torrefaction temperature ranging from 200–350 °C and residence time of 0–50 minutes on the physical and chemical properties of the torrefied product was investigated. Properties of the torrefied product were analyzed on the basis of degree of torrefaction, ultimate and proximate analysis, gas analysis and chemical exergy. The degree of torrefaction and chemical exergy had a positive influence on increasing the torrefaction temperature. Moreover, the effect of torrefaction temperature and residence time on the elemental variation of sewage sludge exhibited an increase in the weight percentage of carbon while the content of H/C and O/C molar ratios decreased. The product gas emitted during torrefaction was analyzed to study the pathway of hydrocarbons and oxygen-containing compounds. The compounds with oxygen were emitted at higher temperatures in contrast to hydrocarbon gases. An attempt was made to obtain the chemical exergy of sewage sludge.

However, it is difficult to achieve uniform and freestanding 1D nanostrcutures over a large area. Here, a simple and novel method was developed for fabrication of universal nanoporous templates for high-density nanostructure arrays, by combining self-assembly of a Si-containing block copolymer with a bilayer lithography system. We introduced a dually responsive photoresist bottom layer into which the nanopatterns of block copolymer are transferred by oxygen reactive ion etching. Because the dually responsive layer becomes cross-linked by heating, it can be used as a hard template during the etching process. It becomes soluble again by chain scission upon exposure to light. Therefore, it can be easily removed by the lift-off process. The template was applicable to the various conducting substrates due to the compatibility of the photoresist with a wide range of substrates and was used in electrodeposition for well-aligned and high-density inorganic and organic nanoarrays. We successfully obtained vertically aligned and highly ordered gold nanorods and polypyrrole dots on the substrate without aggregation, and these arrays did not collapse after removing the dually responsive templates by the simple lift-off process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=block%20copolymer" title="block copolymer">block copolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=dually%20responsive" title=" dually responsive"> dually responsive</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructure" title=" nanostructure"> nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=photoresist" title=" photoresist"> photoresist</a> </p> <a href="https://publications.waset.org/abstracts/36938/fabrication-of-nanostructured-arrays-using-si-containing-block-copolymer-and-dually-responsive-photoresist" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36938.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">257</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">191</span> An Analysis on Gravel of Sand-Gravel Bar at Gneiss or Granite Area of the Upper Hongcheon River in South Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Man%20Kyu%20Kim">Man Kyu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansu%20Shin"> Hansu Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is an analysis on gravel of sand-gravel bar that stretches variously in the Duchon and Naechon stream basins, which are situated on Hong-Cheon River (a well-developed sand-gravel bar in upstream river) basins in Korea.

The characteristics of gravel in the sand-gravel bar of these two branches in the upper Hongcheon River were analyzed in this study in order to understand the geomorphic development of streams depending on the differences of bedrock. Through the analysis on the roundness and flatness of gravel, we figured out an irregular trend following the increase in supply of granite gravel and gneiss gravel as we traveled downstream. The result shows that the two basins have uppermost small basin condition reflecting the mountain valley environment although it may be difficult to do an equivalent comparison to other roundness researches in Korea or in Europe.

In this research project, the effectiveness of numerous thiazole derivatives was explored in inhibiting the PfPKG, a crucial part of the Plasmodium life cycle. This study involved the synthesis of six thiazole-derived amides to inhibit the PfPKG pathway. Nuclear Magnetic Resonance (NMR) spectroscopy and Infrared (IR) spectroscopy were used to characterize these compounds. Furthermore, AutoDocking software was used to predict binding affinities of these thiazole-derived amides in silico. In silico, compound 6 exhibited the highest predicted binding affinity to PfPKG, while compound 5 had the lowest affinity. Compounds 1-4 displayed varying degrees of predicted binding affinity. In-vitro, it was found that compound 4 had the best percent inhibition, while compound 5 had the worst percent inhibition. Overall, all six compounds had weak inhibition (approximately 30-39% at 10 μM), but these results provide a foundation for future drug discovery experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Medicinal%20Chemistry" title="Medicinal Chemistry">Medicinal Chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaria" title=" Malaria"> Malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title=" drug discovery"> drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=PfPKG" title=" PfPKG"> PfPKG</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiazole" title=" Thiazole"> Thiazole</a>, <a href="https://publications.waset.org/abstracts/search?q=Plasmodium" title=" Plasmodium"> Plasmodium</a> </p> <a href="https://publications.waset.org/abstracts/174021/combating-malaria-a-drug-discovery-approach-using-thiazole-derivatives-against-prolific-parasite-enzyme-pfpkg" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174021.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">98</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">189</span> Efficient Delivery of Biomaterials into Living Organism by Using Noble Metal Nanowire Injector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kkochorong%20Park">Kkochorong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Keun%20Cheon%20Kim"> Keun Cheon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoban%20Lee"> Hyoban Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Ju%20Lee"> Eun Ju Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bongsoo%20Kim"> Bongsoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction of biomaterials such as DNA, RNA, proteins is important for many research areas. There are many methods to introduce biomaterials into living organisms like tissue and cells. To introduce biomaterials, several indirect methods including virus‐mediated delivery, chemical reagent (i.e., lipofectamine), electrophoresis have been used. Such methods are passive delivery using an endocytosis process of cell, reducing an efficiency of delivery. Unlike the indirect delivery method, it has been reported that a direct delivery of exogenous biomolecules into nucleus have been more efficient to expression or integration of biomolecules. Nano-sized material is beneficial for detect signal from cell or deliver stimuli/materials into the cell at cellular and molecular levels, due to its similar physical scale. Especially, because 1 dimensional (1D) nanomaterials such as nanotube, nanorod and nanowire with high‐aspect ratio have nanoscale geometry and excellent mechanical, electrical, and chemical properties, they could play an important role in molecular and cellular biology. In this study, by using single crystalline 1D noble metal nanowire, we fabricated nano-sized 1D injector which can successfully interface with living cells and directly deliver biomolecules into several types of cell line (i.e., stem cell, mammalian embryo) without inducing detrimental damages on living cell. This nano-bio technology could be a promising and robust tool for introducing exogenous biomaterials into living organism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20delivery" title=" gene delivery"> gene delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoinjector" title=" nanoinjector"> nanoinjector</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowire" title=" nanowire"> nanowire</a> </p> <a href="https://publications.waset.org/abstracts/62718/efficient-delivery-of-biomaterials-into-living-organism-by-using-noble-metal-nanowire-injector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62718.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">275</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">188</span> Evolution of Floating Photovoltaic System Technology and Future Prospect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Kwan%20Choi">Young-Kwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Sang%20Jeong"> Han-Sang Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Floating photovoltaic system is a technology that combines photovoltaic power generation with floating structure.

Because of the friction heat of air flow with high speed on the surface of the vehicle, it is not easy to cool the superheat of the vehicle by the simple air cooling method. For this reason, a cooling method through endothermic heat is attracting attention by using a fuel that causes an endothermic reaction in a high-speed vehicle. There are two main ways of cooling the fuel through the endothermic reaction. The first is physical heat absorption. When the temperature rises, there is a sensible heat that accompanies it. The second is the heat of reaction corresponding to the chemical heat absorption, which absorbs heat during the fuel decomposes. Generally, since the decomposition reaction of the fuel proceeds at a high temperature, it does not achieve a great efficiency in cooling the high-speed flight body. However, when the catalyst is used, decomposition proceeds at a low temperature thereby increasing the cooling efficiency. However, when the catalyst is used as a powder, the catalyst enters the engine and damages the engine or the catalyst can deteriorate the performance due to the sintering. On the other hand, when used in the form of pellets, catalyst loss can be prevented. However, since the specific surface of pellet is small, the efficiency of the catalyst is low. And it can interfere with the flow of fuel, resulting in pressure loss and problems with fuel injection. In this study, we tried to maximize the performance of the catalyst by preparing a hollow fiber type pellet for zeolite ZSM-5, which has a higher amount of heat absorption, than other conventional pellets. The hollow fiber type pellet was prepared by phase inversion method. The hollow fiber type pellet has a finger-like pore and sponge-like pore. So it has a higher specific surface area than conventional pellets. The crystal structure of the prepared ZSM-5 catalyst was confirmed by XRD, and the characteristics of the catalyst were analyzed by TPD/TPR device. This study was conducted as part of the Basic Research Project (Pure-17-20) of Defense Acquisition Program Administration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalyst" title="catalyst">catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=endothermic%20reaction" title=" endothermic reaction"> endothermic reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20vehicle%20cooling" title=" high-speed vehicle cooling"> high-speed vehicle cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite" title=" zeolite"> zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=ZSM-5" title=" ZSM-5"> ZSM-5</a> </p> <a href="https://publications.waset.org/abstracts/80210/a-study-on-the-performance-improvement-of-zeolite-catalyst-for-endothermic-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80210.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">312</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">186</span> PSRR Enhanced LDO Regulator Using Noise Sensing Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min-ju%20Kwon">Min-ju Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae-won%20Kim"> Chae-won Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-yun%20Seo"> Jeong-yun Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee-guk%20Chae"> Hee-guk Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-seo%20Koo"> Yong-seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we presented the LDO (low-dropout) regulator which enhanced the PSRR by applying the constant current source generation technique through the BGR (Band Gap Reference) to form the noise sensing circuit.

To handle this problem, the method of Lagrange multipliers including classical and localized versions are the most popular technique. It essentially imposes the interface compatibility conditions by introducing Lagrange multipliers. However, the numerical system becomes unstable and inefficient due to the Lagrange multipliers. The interface element-independent formulation that does not include the Lagrange multipliers can be obtained by modifying the independent variables mathematically. Through this modification, more efficient and stable system can be achieved while involving equivalent accuracy comparing with the conventional method.

This time lag effect should be considered in calculating efficiency of decision making units (DMU). Recently, a couple of DEA models were developed for considering time lag effect in efficiency evaluation of research activities. However, these models can’t discriminate efficient DMUs because of the nature of basic DEA model in which efficiency scores are limited to ‘1’. This problem can be resolved a super-efficiency model. However, a super efficiency model sometimes causes infeasibility problem.

Photo-unstable CH2I2 molecules are stabilized via capturing within suprachannels, which is monitored by UV-Vis spectroscopy. Furthermore, the photoluminescence intensity, from the chromophore naphthyl moiety of [ZnCl2L]2, gradually decreases with the addition of CH2I2.

Research has been continuously studied because of the advantage of better dimensional accuracy, smooth surface and improved mechanical properties in the case of drawing. Among them, multipass drawing, which is a method to realize complicated shape by drawing, was discussed in this study. The most important factor in the multipass drawing is the dimensional accuracy and simplify the process. To accomplish this, a multistage shape drawing was performed using various intermediate die shape designs, and finite element analysis was performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEM%20%28Finite%20Element%20Method%29" title="FEM (Finite Element Method)">FEM (Finite Element Method)</a>, <a href="https://publications.waset.org/abstracts/search?q=multipass%20drawing" title=" multipass drawing"> multipass drawing</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediate%20die" title=" intermediate die"> intermediate die</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20pipe" title=" hollow pipe"> hollow pipe</a> </p> <a href="https://publications.waset.org/abstracts/77008/a-study-on-improvement-of-straightness-of-preform-pulling-process-of-hollow-pipe-by-finete-element-analysis-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77008.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">316</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">171</span> Associations between Game Users and Life Satisfaction: The Role of Self-Esteem, Self- Efficacy and Social Capital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hye%20Rim%20Lee">Hye Rim Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Eui%20Jun%20Jeong"> Eui Jun Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Hye%20Yoo"> Ji Hye Yoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study makes an integrated investigation on how life satisfaction is associated with the Korean game users' psychological variables (self-esteem, game and life self- efficacy), social variables (bonding and bridging social capital), and demographic variables (age, gender). The data used for the empirical analysis came from a representative sample survey conducted in South Korea. Results show that self-esteem and game efficacy were an important antecedent to the degree of users’ life satisfaction. Both bonding social capital and bridging social capital enhance the level of the users’ life satisfaction. The importance of perspectives as well as their implications for the game users and further associated research, are explored. <p class="card-text"><strong>Keywords:</strong> <a
