We utilized tunicate cellulose nanowhisker (CNW) as scaffold and developed complex system that can enhance differentiation of osteoblast by applying mechanical stimulation. CNW, a crystal form of cellulose, has high stiffness with a large surface area and is useful as a biomedical material due to its biodegradability and biocompatibility. In this study, CNW was obtained from tunicate extraction and was confirmed for its adhesion, differentiation, growth of osteoblast without cytotoxicity. In addition, osteoblast was successfully differentiated under mechanical stimulation, followed by calcium dependent signaling.

And cellular physiological changes were analyzed from cells cultured in the device. Excessive calcium ion influx through into cytoplasm was induced from mechanical stress. The results revealed that compressed cells had up-regulated Mat3 mRNA which regulates cell size and cell cycle from a prolonged G1 phase. Additionally, TAG used for the production of biodiesel was raised rapidly from 4 h after compression.

When applying this mechanism to the unicellular green algae Chlamydomonas reinhardtii, the dramatic result that the accumulation of intracellular lipid was up to 60% of dry weight basis occurred. Furthermore, various variations in cellular physiology occurred, but there is a lack of the development of the system and related research for applying that technology to control the mechanical stress and facilitate molecular analyses. In this study, applying a mechanical stress to microalgae, the microfluidic device system that finely induced direct membrane distortion of microalgae. Cellular membrane distortion led to deflagellation, calcium influx and lipid accumulation in microalgae.

However, ceramide was too hydrophobic to be directly absorbed into stratum corneum and has risks of side effects by excessive treatment. To overcome the obstacles, ceramide was embedded into PLGA nanoparticles coated with chitosan. PLGA and chitosan have been known as biocompatible materials. PLGA was squeezed when faced with water and pumped ceramide out of PLGA nanoparticle. In addition, the chitosan coating layer helped initial adherence of nanoparticles to skin and regulate ceramide release until removed. This coating was degraded at weakly acid state like skin surface, finally ceramide release could be controlled. Finally, the nanoparticle was demonstrated to be non-cytotoxic and regenerate stratum corneum of atopic dermatitis model. Overall the nanoparticle is suggested as a novel and effective nanodrug to apply atopic dermatitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title="nanoparticle">nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20release" title=" controlled release"> controlled release</a>, <a href="https://publications.waset.org/abstracts/search?q=atopic%20dermatitis" title=" atopic dermatitis"> atopic dermatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan%20coating" title=" chitosan coating"> chitosan coating</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramide" title=" ceramide"> ceramide</a> </p> <a href="https://publications.waset.org/abstracts/50871/ceramide-plga-nanoparticle-formation-to-apply-to-atopic-dermatitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50871.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">394</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">138</span> Suitability Evaluation of CNW as Scaffold for Osteoblast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoo%20Cheol%20Lee">Hoo Cheol Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Seung%20Kim"> Dae Seung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Myung%20Jung"> Sang Myung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwang%20Heum%20Yoon"> Gwang Heum Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwa%20Sung%20Shin"> Hwa Sung Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Loss of bone tissue can occur due to a bone tissue disease and aging or fracture. Renewable formation of bone is mainly made by its differentiation and metabolism. For this reason, osteoblasts have been studied for regeneration of bone tissue. So, tissue engineering has attracted attention as a recovery means. In tissue engineering, a particularly important factor is a scaffold that supports cell growth. For osteoblast scaffold, we used the cellulose nanowhisker (CNW) extracted from marine organism. CNW is one of an abundant material obtained from a number of plants and animals. CNW is polymer consisting of monomer cellulose and this composition offers biodegradability and biocompatibility to CNW. Mechanical strength of CNW is superior to the existing natural polymers. In addition, substances of marine origin have a low risk of secondary infection by bacteria and pathogen in contrast with those of land-derived. For evaluating its suitability as an osteoblast scaffold, we fabricate CNW film for osteoblast culture and performed the MTT assay and ALP assay to confirm its cytotoxicity and effect on differentiation. Taking together these results, we assessed CNW is a potential candidate of a material for bone tissue regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20regeneration" title="bone regeneration">bone regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose%20nanowhisker" title=" cellulose nanowhisker"> cellulose nanowhisker</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20derived%20material" title=" marine derived material"> marine derived material</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title=" osteoblast"> osteoblast</a> </p> <a href="https://publications.waset.org/abstracts/7802/suitability-evaluation-of-cnw-as-scaffold-for-osteoblast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7802.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">137</span> Cellulose Acetate Nanofiber Modification for Regulating Astrocyte Activity via Simple Heat Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sang-Myung%20Jung">Sang-Myung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Hyun%20Ju"> Jeong Hyun Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwang%20Heum%20Yoon"> Gwang Heum Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwa%20Sung%20Shin"> Hwa Sung Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Central nervous system (CNS) consists of neuronal cell and supporting cells. 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. For the results, we highlight that the stiffness is a factor to regulate astrocyte activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astrocyte" title="astrocyte">astrocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose%20acetate" title=" cellulose acetate"> cellulose acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20therapy" title=" cell therapy"> cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness%20of%20scaffold" title=" stiffness of scaffold"> stiffness of scaffold</a> </p> <a href="https://publications.waset.org/abstracts/8514/cellulose-acetate-nanofiber-modification-for-regulating-astrocyte-activity-via-simple-heat-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8514.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">477</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> A Study on the Non-Destructive Test Characterization of Carbon Fiber Reinforced Plastics Using Thermo-Graphic Camera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin">Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee"> Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Ho%20Kim"> Tae Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon%20Sun%20Lee"> Yoon Sun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-destructive testing and evaluation techniques for assessing the integrity of composite structures are essential to both reduce manufacturing costs and out of service time of transport means due to maintenance.

The reason for selecting national parks as the subject of this study was that many Koreans visit national parks on weekends, and their visits continue even as changes are made to the parks. The purpose of this study was to evaluate what type of value perceived by tourists who visit national parks positively influences their satisfaction. Concurrently, the relationship between satisfaction and future behavioral intention was also examined. The understanding and analysis of this relationship is very important for the success of destination tourism development. This analysis can contribute to the creation of a marketing strategy that will induce tourists to stay longer, revisit, and recommend a national park to others. If national park administrators fully utilize the study results, they will be able to increase the number of visitors to their national parks. Furthermore, the results of this study will contribute to the development of Korean national parks as a tourist destination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=national%20park" title="national park">national park</a>, <a href="https://publications.waset.org/abstracts/search?q=visitor%20satisfaction" title=" visitor satisfaction"> visitor satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=loyalty" title=" loyalty"> loyalty</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20management" title=" tourism management"> tourism management</a> </p> <a href="https://publications.waset.org/abstracts/13788/does-the-perceived-value-of-a-national-park-increases-visitor-satisfaction-and-loyalty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13788.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">459</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">134</span> Zero Valent Iron Algal Biocomposite for the Removal of Crystal Violet from Aqueous Solution: Box-Behnken Optimization and Fixed Bed Column Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Jerold">M.

The Box-Behnen design (BBD) experimental results revealed the biosoprtion was maximum at pH 7.5, biosorbent dosage 0.1 g/L and initial CV concentration of 100 mg/L. The effect of various column parameters like bed depth (3, 6 and 9 cm), flow rate (5, 10 and 15 mL/min) and influent CV concentration (5, 10 and 15 mg/L) were investigated. The exhaustion time increased with increase of bed depth, influent CV concentration and decrease of flow rate. Adam-Bohart, Thomas and Yoon-Nelson models were used to predict the breakthrough curve and to evaluate the model parameters. Out of these models, Thomas and Yoon-Nelson models well described the experimental data. Therefore, the result implies that nZVI-SS biocomposite is a cheap and most promising biosorbent for the removal of CV from wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algae" title="algae">algae</a>, <a href="https://publications.waset.org/abstracts/search?q=biosorption" title=" biosorption"> biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-valent" title=" zero-valent"> zero-valent</a>, <a href="https://publications.waset.org/abstracts/search?q=dye" title=" dye"> dye</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/114454/zero-valent-iron-algal-biocomposite-for-the-removal-of-crystal-violet-from-aqueous-solution-box-behnken-optimization-and-fixed-bed-column-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114454.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">195</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">133</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.

A time instant was recognized as FOG if the mean amplitude of the acceleration in the time window surrounding the time instant was in the specific FOG range.

Various low cost adsorbents have been studied for their applicability in treatment of different types of effluents. In this work, the intention of the study was to explore the efficacy and feasibility for azo dye, Acid Orange 7 (AO7) adsorption onto fixed bed column of NaOH Treated eggshell (TES). The effect of various parameters like flow rate, initial dye concentration, and bed height were exploited in this study. The studies confirmed that the breakthrough curves were dependent on flow rate, initial dye concentration solution of AO7 and bed depth. The Thomas, Yoon–Nelson, and Adams and Bohart models were analysed to evaluate the column adsorption performance. The adsorption capacity, rate constant and correlation coefficient associated to each model for column adsorption was calculated and mentioned. The column experimental data were fitted well with Thomas model with coefficients of correlation R2 ≥0.93 at different conditions but the Yoon–Nelson, BDST and Bohart–Adams model (R2=0.911), predicted poor performance of fixed-bed column. The (TES) was shown to be suitable adsorbent for adsorption of AO7 using fixed-bed adsorption column. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20models" title="adsorption models">adsorption models</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20orange%207" title=" acid orange 7"> acid orange 7</a>, <a href="https://publications.waset.org/abstracts/search?q=bed%20depth" title=" bed depth"> bed depth</a>, <a href="https://publications.waset.org/abstracts/search?q=breakthrough" title=" breakthrough"> breakthrough</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20adsorption" title=" dye adsorption"> dye adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed-bed%20column" title=" fixed-bed column"> fixed-bed column</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20eggshell" title=" treated eggshell"> treated eggshell</a> </p> <a href="https://publications.waset.org/abstracts/43408/continuous-fixed-bed-reactor-application-for-decolourization-of-textile-effluent-by-adsorption-on-naoh-treated-eggshell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43408.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">377</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">130</span> A Case Study: Teachers Education Program in a Global Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=In%20Hoi%20Lee">In Hoi Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Baeg%20Kim"> Seong Baeg Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Je%20Eung%20Jeon"> Je Eung Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwang%20Yong%20Choi"> Gwang Yong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Joo%20Sub%20Lee"> Joo Sub Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ik%20Sang%20Kim"> Ik Sang Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the interest of globalization in the field of teacher education has increased. In the U.S., the government is trying to enhance the quality of education through a global approach in education. To do so, the schools in the U.S. are recruiting teachers with global capability from countries like Korea where competent teachers are being trained. Meanwhile, in the case of Korea, although excellent teachers have been cultivated every year, due to a low birth rate it is not easy to become a domestic teacher. To solve the trouble that the two countries are facing, the study first examines the demand and necessity of globalization in the field of teacher education between Korea and the U.S. Second, we propose a new project, called the ‘Global Teachers University (GTU)’ program to satisfy the demands of both countries. Finally, we provide its implications to build the future educational cooperation for teacher training in a global context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20cooperation" title="educational cooperation">educational cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%20education%20program" title=" teachers education program"> teachers education program</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20training%20institutions" title=" teacher training institutions"> teacher training institutions</a> </p> <a href="https://publications.waset.org/abstracts/3525/a-case-study-teachers-education-program-in-a-global-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3525.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">501</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 Study on Automotive Attack Database and Data Flow Diagram for Concretization of HEAVENS: A Car Security Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Se-Han%20Lee">Se-Han Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwang-Woo%20Go"> Kwang-Woo Go</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwang-Hyun%20Ahn"> Gwang-Hyun Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee-Sung%20Park"> Hee-Sung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheol-Kyu%20Han"> Cheol-Kyu Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Bo%20Shim"> Jun-Bo Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Geun-Chul%20Kang"> Geun-Chul Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jung%20Lee"> Hyun-Jung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, with the advent of smart cars and the expansion of the market, the announcement of 'Adventures in Automotive Networks and Control Units' at the DEFCON21 conference in 2013 revealed that cars are not safe from hacking. As a result, the HEAVENS model considering not only the functional safety of the vehicle but also the security has been suggested. However, the HEAVENS model only presents a simple process, and there are no detailed procedures and activities for each process, making it difficult to apply it to the actual vehicle security vulnerability check. In this paper, we propose an automated attack database that systematically summarizes attack vectors, attack types, and vulnerable vehicle models to prepare for various car hacking attacks, and data flow diagrams that can detect various vulnerabilities and suggest a way to materialize the HEAVENS model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20security" title="automotive security">automotive security</a>, <a href="https://publications.waset.org/abstracts/search?q=HEAVENS" title=" HEAVENS"> HEAVENS</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20hacking" title=" car hacking"> car hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20model" title=" security model"> security model</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a> </p> <a href="https://publications.waset.org/abstracts/84442/a-study-on-automotive-attack-database-and-data-flow-diagram-for-concretization-of-heavens-a-car-security-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84442.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">128</span> Analyses for Primary Coolant Pump Coastdown Phenomena for Jordan Research and Training Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yazan%20M.%20Alatrash">Yazan M.

In this study, primary coolant flow coastdown phenomena are investigated for the Jordan Research and Training Reactor (JRTR) using a simulation software package, Modular Modelling System (MMS). Two MMS models are built. The first one is a simple model to investigate the characteristics of the primary coolant pump only. The second one is a model for a simulation of the Primary Coolant System (PCS) loop, in which all the detailed design data of the JRTR PCS system are modelled, including the geometrical arrangement data. The same design data for a PCS pump are used for both models. Coastdown curves obtained from the two models are compared to study the PCS loop coolant inertia effect on a flow coastdown. Results showed that the loop coolant inertia effect is found to be small in the JRTR PCS loop, i.e., about one second increases in a coastdown half time required to halve the coolant flow rate. The effects of different flywheel inertia on the flow coastdown are also investigated. It is demonstrated that the coastdown half time increases with the flywheel inertia linearly. The designed coastdown half time is proved to be well above the design requirement for the fuel integrity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20coastdown" title="flow coastdown">flow coastdown</a>, <a href="https://publications.waset.org/abstracts/search?q=loop%20inertia" title=" loop inertia"> loop inertia</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20reactor" title=" research reactor"> research reactor</a> </p> <a href="https://publications.waset.org/abstracts/2606/analyses-for-primary-coolant-pump-coastdown-phenomena-for-jordan-research-and-training-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2606.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">502</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">127</span> Comparison of Adsorbents for Ammonia Removal from Mining Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Al-Sheikh">F.

Elkamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ammonia in mining wastewater is a significant problem, and treatment can be especially difficult in cold climates where biological treatment is not feasible. An adsorption process is one of the alternative processes that can be used to reduce ammonia concentrations to acceptable limits, and therefore a LEWATIT resin strongly acidic H+ form ion exchange resin and a Bowie Chabazite Na form AZLB-Na zeolite were tested to assess their effectiveness. For these adsorption tests, two packed bed columns (a mini-column constructed from a 32-cm long x 1-cm diameter piece of glass tubing, and a 60-cm long x 2.5-cm diameter Ace Glass chromatography column) were used containing varying quantities of the adsorbents. A mining wastewater with ammonia concentrations of 22.7 mg/L was fed through the columns at controlled flowrates. In the experimental work, maximum capacities of the LEWATIT ion exchange resin were 0.438, 0.448, and 1.472 mg/g for 3, 6, and 9 g respectively in a mini column and 1.739 mg/g for 141.5 g in a larger Ace column while the capacities for the AZLB-Na zeolite were 0.424, and 0.784 mg/g for 3, and 6 g respectively in the mini column and 1.1636 mg/g for 38.5 g in the Ace column. In the theoretical work, Thomas, Adams-Bohart, and Yoon-Nelson models were constructed to describe a breakthrough curve of the adsorption process and find the constants of the above-mentioned models. In the regeneration tests, 5% hydrochloric acid, HCl (v/v) and 10% sodium hydroxide, NaOH (w/v) were used to regenerate the LEWATIT resin and AZLB-Na zeolite with 44 and 63.8% recovery, respectively. In conclusion, continuous flow adsorption using a LEWATIT ion exchange resin and an AZLB-Na zeolite is efficient when using a co-flow technique for removal of the ammonia from wastewater.

The axial piston pump is a type of positive displacement pump that has several pistons in a circular array within a cylinder block. As the cylinder block and pistons start to rotate, since the exposed ends of the pistons are constrained to follow the surface of the swashed plate, the pistons are driven to reciprocate axially and then a hydraulic power is produced. In the present study, a numerical simulation which has three dimensional full model of the axial piston pump was carried out using a commercial CFD code (Ansys CFX 14.5). In order to take into consideration motion of compression and extension by the reciprocating pistons, the moving boundary conditions were applied as a function of the rotation angle to that region. In addition, this pump using hydraulic oil as working fluid is intentionally designed as a small amount of oil leaks out in order to lubricate moving parts. Since leakage could directly affect the pump efficiency, evaluation of effect of oil-leakage is very important. In order to predict the effect of the oil leakage on the pump efficiency, we considered the leakage between piston-shoe and swash-plate by modeling cylindrical shaped-feature at the end of the cylinder. In order to validate the numerical method used in this study, the numerical results of the flow rate at the discharge port are compared with the experimental data, and good agreement between them was shown. Using the validated numerical method, the effect of the discharge pressure was also investigated. The result of the present study can be useful information of small axial piston pump used in many different manufacturing industries.

Different simulation devices are also being developed for military equipment training. This is to address the concerns regarding safety accidents as well as cost issues associated with training with expensive equipment. An important aspect of developing simulation devices to replicate military training is that trainees experience the same effect as training with real devices. In this study, the criteria for performance evaluation are established to compare the training effect of an MR-based simulation device to that of an actual device. K-9 Self-propelled artillery (SPA) operators are selected as training subjects. First, MR-based software is developed to simulate the training ground and training scenarios currently used for training SPA operators in South Korea. Hardware that replicates the interior of SPA is designed, and a simulation device that is linked to the software is developed. Second, criteria are established to evaluate the simulation device based on real-life training scenarios. A total of nine performance evaluation criteria were selected based on the actual SPA operation training scenarios. Evaluation items were selected to evaluate whether the simulation device was designed such that trainees would experience the same effect as training in the field with a real SPA. To eval-uate the level of replication by the simulation device of the actual training environments (driving and passing through trenches, pools, protrusions, vertical obstacles, and slopes) and driving conditions (rapid steering, rapid accelerating, and rapid braking) as per the training scenarios, tests were performed under the actual training conditions and in the simulation device, followed by the comparison of the results. In addition, the level of noise felt by operators during training was also selected as an evaluation criterion. Due to the nature of the simulation device, there may be data latency between HW and SW. If the la-tency in data transmission is significant, the VR image information delivered to trainees as they maneuver HW might not be consistent. This latency in data transmission was also selected as an evaluation criterion to improve the effectiveness of the training. Through this study, the key evaluation metrics were selected to achieve the same training effect as training with real equipment in a training ground during the develop-ment of the simulation device for military equipment training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=K-9%20self-propelled%20artillery" title="K-9 self-propelled artillery">K-9 self-propelled artillery</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20reality" title=" mixed reality"> mixed reality</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20device" title=" simulation device"> simulation device</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronization" title=" synchronization"> synchronization</a> </p> <a href="https://publications.waset.org/abstracts/181405/a-study-on-the-establishment-of-performance-evaluation-criteria-for-mr-based-simulation-device-to-train-k-9-self-propelled-artillery-operators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181405.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">66</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">120</span> A Cooperative Space-Time Transmission Scheme Based On Symbol Combinations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keunhong%20Chae">Keunhong Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokho%20Yoon"> Seokho Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a cooperative Alamouti space time transmission scheme with low relay complexity for the cooperative communication systems.

However, not only fast neutrons but also thermal neutrons, epithermal neutrons and gamma exist in the nuclear reactor. And the electrical properties of the IGBT may be deteriorated by the irradiation of gamma. Gamma irradiation damages are known to be caused by Total Ionizing Dose (TID) effect and Single Event Effect (SEE), Displacement Damage. Especially, the TID effect deteriorated the electrical properties such as leakage current and threshold voltage of a power semiconductor. This work can confirm the effect of the gamma irradiation on the electrical properties of 600 V NPT-IGBT. Irradiation of gamma forms lattice defects in the gate oxide and Si-SiO<sub>2</sub> interface of the IGBT. It was confirmed that this lattice defect acts on the center of the trap and affects the threshold voltage, thereby negatively shifted the threshold voltage according to TID. In addition to the change in the carrier mobility, the conductivity modulation decreases in the n-drift region, indicating a negative influence that the forward voltage drop decreases. The turn-off delay time of the device before irradiation was 212 ns. Those of 2.5, 10, 30, 70 and 100 kRad(Si) were 225, 258, 311, 328, and 350 ns, respectively. The gamma irradiation increased the turn-off delay time of the IGBT by approximately 65%, and the switching characteristics deteriorated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NPT-IGBT" title="NPT-IGBT">NPT-IGBT</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20irradiation" title=" gamma irradiation"> gamma irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=switching" title=" switching"> switching</a>, <a href="https://publications.waset.org/abstracts/search?q=turn-off%20delay%20time" title=" turn-off delay time"> turn-off delay time</a>, <a href="https://publications.waset.org/abstracts/search?q=recombination" title=" recombination"> recombination</a>, <a href="https://publications.waset.org/abstracts/search?q=trap%20center" title=" trap center"> trap center</a> </p> <a href="https://publications.waset.org/abstracts/93282/modification-of-electrical-and-switching-characteristics-of-a-non-punch-through-insulated-gate-bipolar-transistor-by-gamma-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93282.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">155</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">117</span> Determination of Concentrated State Using Multiple EEG Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae%20Jin%20Choi">Tae Jin Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Ok%20Kim"> Jong Ok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Min%20Jin"> Sang Min Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilwon%20Yoon"> Gilwon Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of EEG brainwave provides information on mental or emotional states.

A numerical example is presented to illustrate our theoretic findings in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broadcasting%20control" title="broadcasting control">broadcasting control</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-agent%20system" title=" multi-agent system"> multi-agent system</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20function" title=" transfer function"> transfer function</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a> </p> <a href="https://publications.waset.org/abstracts/11214/broadcasting-stabilization-for-dynamical-multi-agent-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11214.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">380</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">115</span> Robust Stabilization against Unknown Consensus Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myung-Gon%20Yoon">Myung-Gon Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Ho%20Moon"> Jung-Ho Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers a robust stabilization problem of a single agent in a multi-agent consensus system composed of identical agents, when the network topology of the system is completely unknown. It is shown that the transfer function of an agent in a consensus system can be described as a multiplicative perturbation of the isolated agent transfer function in frequency domain.

First we elucidate the viscoelastic behavior of collagen molecules whose diameter is a couple of nanometers. By using the molecular dynamics simulation, we observed the viscoelastic behavior in different pulling velocity. Second, the protein layer, so called ‘sheath’ in enamel microstructure reduces the stress concentration in enamel minerals. We examined the result by using the finite element methods. Third, the anisotropic elastic constants of dentin are estimated by micromechanical analysis and estimated results are close to the experimentally measured data. Last, new formulation between the fabric tensor and the wave velocity is established for calcaneus by employing the poroelasticity. This formulation can be simply used for future experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tissues" title="tissues">tissues</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanics" title=" mechanics"> mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20propagation" title=" wave propagation"> wave propagation</a> </p> <a href="https://publications.waset.org/abstracts/34027/mechanical-properties-of-biological-tissues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34027.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">372</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">113</span> Analysis on Thermococcus achaeans with Frequent Pattern Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeongyeob%20Hong">Jeongyeob Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Myeonghoon%20Park"> Myeonghoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Taeson%20Yoon"> Taeson Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> After the advent of Achaeans which utilize different metabolism pathway and contain conspicuously different cellular structure, they have been recognized as possible materials for developing quality of human beings. Among diverse Achaeans, in this paper, we compared 16s RNA Sequences of four different species of Thermococcus: Achaeans genus specialized in sulfur-dealing metabolism. Four Species, Barophilus, Kodakarensis, Hydrothermalis, and Onnurineus, live near the hydrothermal vent that emits extreme amount of sulfur and heat. By comparing ribosomal sequences of aforementioned four species, we found similarities in their sequences and expressed protein, enabling us to expect that certain ribosomal sequence or proteins are vital for their survival. Apriori algorithms and Decision Tree were used. for comparison. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achaeans"
