At the same time, consumers pay more attention on the healthy fat, especially on unsaturated fatty acids. These long chain carbohydrates reduce heart diseases, improve memory and eye sight and activate the immune system. One of the important issues to be solved for our Mongolia’s food security is to provide healthy, fresh, widely available and cheap meat for the population. Thus, an importance of the Selenge breed meat production is increasing in order to supply the quality meat food security since the Selenge breed cattle are rapidly multiplied, beneficial in term of income, the same quality as Mongolian breed, and well digested for human body. We researched the lipid, unsaturated and saturated fatty acid contents of meat of Selenge breed younger cattle by their muscle types. Result of our research reveals that 11 saturated fatty acids are detected. For the content of palmitic acid among saturated fatty acids, 23.61% was in the sirloin meat, 24.01% was in the round and chuck meat, and 24.83% was in the short loin meat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chromatogram" title="chromatogram">chromatogram</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography" title=" gas chromatography"> gas chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20resolving" title=" organic resolving"> organic resolving</a>, <a href="https://publications.waset.org/abstracts/search?q=saturated%20and%20unsaturated%20fatty%20acids" title=" saturated and unsaturated fatty acids"> saturated and unsaturated fatty acids</a> </p> <a href="https://publications.waset.org/abstracts/55605/result-of-fatty-acid-content-in-meat-of-selenge-breed-younger-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55605.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">268</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">154</span> Transcriptome Analysis of Protestia brevitarsis seulensis with Focus On Wing Development and Metamorphosis in Developmental Stages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihye%20Hwang">Jihye Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Hwa%20Choi"> Eun Hwa Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Youn%20Baek"> Su Youn Baek</a>, <a href="https://publications.waset.org/abstracts/search?q=Bia%20Park"> Bia Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyeongmin%20Kim"> Gyeongmin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chorong%20Shin"> Chorong Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Ha%20Lee"> Joon Ha Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Sam%20Hwang"> Jae-Sam Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ui%20Wook%20Hwang"> Ui Wook Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> White-spotted flower chafers are widely distributed in Asian countries and traditionally used for the treatment of chronic fatigue, blood circulation, and paralysis in the oriental medicine field. The evolution and development of insect wings and metamorphosis remain under-discovered subjects in arthropod evolutionary researches. Gene expression abundance analyses along with developmental stages based on the large-scale RNA-seq data are also still rarely done. Here we report the de novo assembly of a Protestia brevitarsis seulensis transcriptome along four different developmental stages (egg, larva, pupa, and adult) to explore its development and evolution of wings and metamorphosis. The de novo transcriptome assembly consists of 23,551 high-quality transcripts and is approximately 96.7% complete. Out of 8,545 transcripts, 5,183 correspond to the possible orthologs with Drosophila melanogaster. As a result, we could found 265 genes related to wing development and 19 genes related to metamorphosis. The comparison of transcript expression abundance with different developmental stages revealed developmental stage-specific transcripts especially working at the stage of wing development and metamorphosis of P. b. seulensis. This transcriptome quantification along the developmental stages may provide some meaningful clues to elucidate the genetic modulation mechanism of wing development and metamorphosis obtained during the insect evolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=white-spotted%20flower%20chafers" title="white-spotted flower chafers">white-spotted flower chafers</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptomics" title=" transcriptomics"> transcriptomics</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA-seq" title=" RNA-seq"> RNA-seq</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20biology" title=" network biology"> network biology</a>, <a href="https://publications.waset.org/abstracts/search?q=wing%20development" title=" wing development"> wing development</a>, <a href="https://publications.waset.org/abstracts/search?q=metamorphosis" title=" metamorphosis"> metamorphosis</a> </p> <a href="https://publications.waset.org/abstracts/138739/transcriptome-analysis-of-protestia-brevitarsis-seulensis-with-focus-on-wing-development-and-metamorphosis-in-developmental-stages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138739.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">229</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">153</span> Generation of Charged Nanoparticles and Their Contribution to the Thin Film and Nanowire Growth during Chemical Vapour Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Min%20Yang">Seung-Min Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Han%20Park"> Seong-Han Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Hoon%20Lee"> Sang-Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Wan%20Yoo"> Seung-Wan Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Chan-Soo%20Kim"> Chan-Soo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nong-Moon%20Hwang"> Nong-Moon Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The theory of charged nanoparticles suggested that in many Chemical Vapour Depositions (CVD) processes, Charged Nanoparticles (CNPs) are generated in the gas-phase and become a building block of thin films and nanowires. Recently, the nanoparticle-based crystallization has become a big issue since the growth of nanorods or crystals by the building block of nanoparticles was directly observed by transmission electron microscopy observations in the liquid cell. In an effort to confirm charged gas-phase nuclei, that might be generated under conventional processing conditions of thin films and nanowires during CVD, we performed an in-situ measurement using differential mobility analyser and particle beam mass spectrometer. The size distribution and number density of CNPs were affected by process parameters such as precursor flow rate and working temperature. It was shown that many films and nanostructures, which have been believed to grow by individual atoms or molecules, actually grow by the building blocks of such charged nuclei. The electrostatic interaction between CNPs and the growing surface induces the self-assembly into films and nanowires. In addition, the charge-enhanced atomic diffusion makes CNPs liquid-like quasi solid. As a result, CNPs tend to land epitaxial on the growing surface, which results in the growth of single crystalline nanowires with a smooth surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapour%20deposition" title="chemical vapour deposition">chemical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=charged%20nanoparticle" title=" charged nanoparticle"> charged nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20force" title=" electrostatic force"> electrostatic force</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructure%20evolution" title=" nanostructure evolution"> nanostructure evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20mobility%20analyser" title=" differential mobility analyser"> differential mobility analyser</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20beam%20mass%20spectrometer" title=" particle beam mass spectrometer"> particle beam mass spectrometer</a> </p> <a href="https://publications.waset.org/abstracts/2492/generation-of-charged-nanoparticles-and-their-contribution-to-the-thin-film-and-nanowire-growth-during-chemical-vapour-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2492.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">451</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">152</span> LGR5 and Downstream Intracellular Signaling Proteins Play Critical Roles in the Cell Proliferation of Neuroblastoma, Meningioma and Pituitary Adenoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Hwan%20Cheong">Jin Hwan Cheong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mina%20Hwang"> Mina Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung%20Hoon%20Han"> Myung Hoon Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Je%20Il%20Ryu"> Je Il Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20ha%20Oh"> Young ha Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Ho%20Koh"> Seong Ho Koh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wu%20Duck%20Won"> Wu Duck Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Jin%20Ha"> Byung Jin Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) has been reported to play critical roles in the proliferation of various cancer cells. However, the roles of LGR5 in brain tumors and the specific intracellular signaling proteins directly associated with it remain unknown. Expression of LGR5 was first measured in normal brain tissue, meningioma, and pituitary adenoma of humans. To identify the downstream signaling pathways of LGR5, siRNA-mediated knockdown of LGR5 was performed in SH-SY5Y neuroblastoma cells followed by proteomics analysis with 2-dimensional polyacrylamide gel electrophoresis (2D-PAGE). In addition, the expression of LGR5-associated proteins was evaluated in LGR5-inꠓhibited neuroblastoma cells and in human normal brain, meningioma, and pituitary adenoma tissue. Proteomics analysis showed 12 protein spots were significantly different in expression level (more than two-fold change) and subsequently identified by peptide mass fingerprinting. A protein association network was constructed from the 12 identified proteins altered by LGR5 knockdown. Direct and indirect interactions were identified among the 12 proteins. HSP 90-beta was one of the proteins whose expression was altered by LGR5 knockdown. Likewise, we observed decreased expression of proteins in the hnRNP subfamily following LGR5 knockdown. In addition, we have for the first time identified significantly higher hnRNP family expression in meningioma and pituitary adenoma compared to normal brain tissue. Taken together, LGR5 and its downstream sigꠓnaling play critical roles in neuroblastoma and brain tumors such as meningioma and pituitary adenoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LGR5" title="LGR5">LGR5</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroblastoma" title=" neuroblastoma"> neuroblastoma</a>, <a href="https://publications.waset.org/abstracts/search?q=meningioma" title=" meningioma"> meningioma</a>, <a href="https://publications.waset.org/abstracts/search?q=pituitary%20adenoma" title=" pituitary adenoma"> pituitary adenoma</a>, <a href="https://publications.waset.org/abstracts/search?q=hnRNP" title=" hnRNP"> hnRNP</a> </p> <a href="https://publications.waset.org/abstracts/180812/lgr5-and-downstream-intracellular-signaling-proteins-play-critical-roles-in-the-cell-proliferation-of-neuroblastoma-meningioma-and-pituitary-adenoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180812.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">56</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">151</span> Regulation of Differentiating Intramuscular Stromal Vascular Cells Isolated from Hanwoo Beef Cattle by Retinoic Acid and Calcium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seong%20Gu%20Hwang">Seong Gu Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Kyoon%20Oh">Young Kyoon Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20F.%20dela%20Cruz"> Joseph F. dela Cruz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marbling, or intramuscular fat, has been consistently identified as one of the top beef quality problems. Intramuscular adipocytes distribute throughout the perimysial connective tissue of skeletal muscle and are the major site for the deposition of intramuscular fat, which is essential for the eating quality of meat. The stromal vascular fraction of the skeletal muscle contains progenitor cells that can be enhanced to differentiate to adipocytes and increase intramuscular fat. Primary cultures of bovine intramuscular stromal vascular cells were used in this study to elucidate the effects of extracellular calcium and retinoic acid concentration on adipocyte differentiation. Cell viability assay revealed that even at different concentrations of calcium and retinoic acid, there was no significant difference on cell viability. Monitoring of the adipocyte differentiation showed that bovine intramuscular stromal vascular cells cultured in a low concentration of extracellular calcium and retinoic acid had a better degree of fat accumulation. The mRNA and protein expressions of PPARγ, C/EBPα, SREBP-1c and aP2 were analyzed and showed a significant upregulation upon the reduction in the level of extracellular calcium and retinoic acid. The upregulation of these adipogenic related genes means that the decreasing concentration of calcium and retinoic acid is able to stimulate the adipogenic differentiation of bovine intramuscular stromal vascular cells. To further elucidate the effect of calcium, the expression level of calreticulin was measured. Calreticulin which is known to be an inhibitor of PPARγ was down regulated by the decreased level of calcium and retinoic acid in the culture media. The same tendency was observed on retinoic acid receptors RARα and CRABP-II. These receptors are recognized as adipogenic inhibitors, and the downregulation of their expression allowed a better level of differentiation in bovine intramuscular stromal vascular cells. In conclusion, data show that decreasing the level of extracellular calcium and retinoic acid can significantly promote adipogenesis in intramuscular stromal vascular cells of Hanwoo beef cattle. These findings may provide new insights in enhancing intramuscular adipogenesis and marbling in beef cattle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium" title="calcium">calcium</a>, <a href="https://publications.waset.org/abstracts/search?q=calreticulin" title=" calreticulin"> calreticulin</a>, <a href="https://publications.waset.org/abstracts/search?q=hanwoo%20beef" title=" hanwoo beef"> hanwoo beef</a>, <a href="https://publications.waset.org/abstracts/search?q=retinoic%20acid" title=" retinoic acid"> retinoic acid</a> </p> <a href="https://publications.waset.org/abstracts/31990/regulation-of-differentiating-intramuscular-stromal-vascular-cells-isolated-from-hanwoo-beef-cattle-by-retinoic-acid-and-calcium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31990.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">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">150</span> Effects of Blood Pressure According to Age on End-Stage Renal Disease Development in Diabetes Mellitus Patients: A Nationwide Population-Based Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eun%20Hui%20Bae">Eun Hui Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Yeob%20Lim"> Sang Yeob Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Bongseong%20Kim"> Bongseong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Ryom%20Oh"> Tae Ryom Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Hyun%20Song"> Su Hyun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Heon%20Suh"> Sang Heon Suh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Sang%20Choi"> Hong Sang Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Mi%20Yang"> Eun Mi Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Seong%20Kim"> Chang Seong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Kwon%20Ma"> Seong Kwon Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Do%20Han"> Kyung-Do Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Wan%20Kim"> Soo Wan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Recent hypertension guidelines have recommended lower blood pressure (BP) targets in high-risk patients. However, there are no specific guidelines based on age or systolic and diastolic blood pressure (SBP and DBP, respectively). We aimed to assess the effects of age-related BP on the development of end-stage renal disease (ESRD) in patients with diabetes. Methods: A total of 2,563,870 patients with DM aged >20 years were selected from the Korean National Health Screening Program from 2009 to 2012 and followed up until the end of 2019. Participants were categorized into age and BP groups, and the hazard ratios (HRs) for ESRD were calculated. Results: During a median follow-up of 7.15 years, the incidence rates of ESRD increased with increasing SBP and DBP. The HR for ESRD was the highest in patients younger than 40 years of age with DBP ≥ 100 mmHg. The effect of SBP and DBP on ESRD development was attenuated with age (interaction p-value was <0.0001 for age and SBP and 0.0022 for age and DBP). The subgroup analysis for sex, anti-hypertension medication, and history of chronic kidney disease (CKD) showed higher HRs for ESRD among males younger than 40 years, not taking anti-hypertension medications and CKD compared to those among females older than 40 years, anti-hypertension medication and non-CKD groups. Conclusions: Higher SBP and DBP increase the risk of developing ESRD in patients with diabetes, and in particular, younger individuals face greater risk. Therefore, intensive BP management is warranted in younger patients to prevent ESRD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypertension" title="hypertension">hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adult" title=" young adult"> young adult</a>, <a href="https://publications.waset.org/abstracts/search?q=end-stage%20renal%20disease" title=" end-stage renal disease"> end-stage renal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20kidney%20disease" title=" chronic kidney disease"> chronic kidney disease</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure" title=" blood pressure"> blood pressure</a> </p> <a href="https://publications.waset.org/abstracts/149411/effects-of-blood-pressure-according-to-age-on-end-stage-renal-disease-development-in-diabetes-mellitus-patients-a-nationwide-population-based-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149411.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">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">149</span> Some Issues with Extension of an HPC Cluster</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pil%20Seong%20Park">Pil Seong Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Homemade HPC clusters are widely used in many small labs, because they are easy to build and cost-effective. Even though incremental growth is an advantage of clusters, it results in heterogeneous systems anyhow. Instead of adding new nodes to the cluster, we can extend clusters to include some other Internet servers working independently on the same LAN, so that we can make use of their idle times, especially during the night. However extension across a firewall raises some security problems with NFS. In this paper, we propose a method to solve such a problem using SSH tunneling, and suggest a modified structure of the cluster that implements it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extension%20of%20HPC%20clusters" title="extension of HPC clusters">extension of HPC clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=NFS" title=" NFS"> NFS</a>, <a href="https://publications.waset.org/abstracts/search?q=SSH%20tunneling" title=" SSH tunneling"> SSH tunneling</a> </p> <a href="https://publications.waset.org/abstracts/8521/some-issues-with-extension-of-an-hpc-cluster" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8521.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">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">148</span> The Analysis of Questionnaires about the Health Condition of Students Involved in the Korean Medicine Doctors` Visiting School Program-Cohort Study: Middle and High School Participator of Seong-Nam-</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narae%20Yang">Narae Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Sung"> Hyun Kyung Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Seon%20Mi%20Shin"> Seon Mi Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jung"> Hee Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Ji%20Kim"> Yong Ji Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Yong%20Park"> Tae-Yong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Yeon%20Go"> Ho Yeon Go</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to build base-line data for the Korean Medicine Doctors` Visiting School Program (KMDVSP) by analyzing a student health survey filled out by the students. Korean medicine doctors assigned to 20 middle and high schools in Seong-nam visited these schools eight times in five months. During each visit, the assigned doctors performed health consultations and Korean medicine treatment, and taught health education classes. 12115 students answered self-reported questionnaires about their own physical condition at the beginning of the program. In a question about pain, 7080(58%) reported having a headache, while 4048(33%) said they had a backache, nuchal pain/shoulder pain was reported by 5993(49%), dyspepsia was present in 2736(23%), rhinitis/sinusitis was reported by 4176(34%), coughing/dyspnea by 7102(59%), itching/skin rash by 2840(23%), and constipation was reported by 1091(9%), while 2264(18%) said they had diarrhea. Increased urinary frequency/feeling of residual urine was reported by 569 students (5%), and 3324(27%) said they had insomnia/fitful sleep/morning fatigue. When asked about menstruation, 4450(83%) of the female students reported irregular menstruation or said they experienced menstrual pain. Understanding the health condition of adolescent students is the starting point to determining national health policy to prevent various diseases in the future. We have developed the pilot project of KMDVSP and collected research about students’ health. Based on this data, further studies should be performed in order to develop a cooperative program between schools and the Korean medical center. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=korean%20medicine%20doctors%60%20visiting%20school%20program%28kmdvsp%29" title="korean medicine doctors` visiting school program(kmdvsp)">korean medicine doctors` visiting school program(kmdvsp)</a>, <a href="https://publications.waset.org/abstracts/search?q=student%60s%20health%20condition" title=" student`s health condition"> student`s health condition</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaires" title=" questionnaires"> questionnaires</a>, <a href="https://publications.waset.org/abstracts/search?q=cohort%20study" title=" cohort study "> cohort study </a> </p> <a href="https://publications.waset.org/abstracts/66988/the-analysis-of-questionnaires-about-the-health-condition-of-students-involved-in-the-korean-medicine-doctors-visiting-school-program-cohort-study-middle-and-high-school-participator-of-seong-nam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66988.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">478</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">147</span> A Development of Personalized Edutainment Contents through Storytelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Kyeong%20Cha">Min Kyeong Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Yeon%20Mun"> Ju Yeon Mun</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Baeg%20Kim"> Seong Baeg Kim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, ‘play of learning’ became important and is emphasized as a useful learning tool.

In order to realize immediate fault tolerance, corrective control theory is applied to designing a dynamic feedback controller. Existence conditions for an appropriate controller and its construction algorithm are presented in terms of reachability of the machine and the feature of fault occurrences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asynchronous%20sequential%20machines" title="asynchronous sequential machines">asynchronous sequential machines</a>, <a href="https://publications.waset.org/abstracts/search?q=corrective%20control" title=" corrective control"> corrective control</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20diagnosis%20and%20tolerance" title=" fault diagnosis and tolerance"> fault diagnosis and tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20detector" title=" fault detector"> fault detector</a> </p> <a href="https://publications.waset.org/abstracts/53634/asynchronous-sequential-machines-with-fault-detectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53634.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">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">145</span> Experimental Study on the Floor Vibration Evaluation of Concrete Slab for Existing Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong-Taeg%20Lee">Yong-Taeg Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Ho%20Na"> Jun-Ho Na</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Hun%20Kim"> Seung-Hun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Uk%20Hong"> Seong-Uk Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Damages from noise and vibration are increasing every year, most of which are noises between floors in deteriorated building caused by floor impact sound.

Roll-forming is a key technology among the manufacturing process of reed wire using textile machine. A simulation of roll-forming line in accordance with the reduction rate is performed using LS-DYNA. The upper roller, fixed roller and reed wire are modeled by finite element. The roller is set to be rigid body and the wire of SUS430 is set to be flexible body. We predict the variation of the cross-sectional shape of the wire depending on the reduction ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=textile%20machine" title="textile machine">textile machine</a>, <a href="https://publications.waset.org/abstracts/search?q=reed" title=" reed"> reed</a>, <a href="https://publications.waset.org/abstracts/search?q=rolling" title=" rolling"> rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction%20ratio" title=" reduction ratio"> reduction ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=wire" title=" wire"> wire</a> </p> <a href="https://publications.waset.org/abstracts/50434/analysis-of-roll-forming-for-high-density-wire-of-reed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50434.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">374</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">139</span> Angle of Arrival Estimation Using Maximum Likelihood Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olomon%20Wu">Olomon Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung%20Lu"> Hung Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Wilkins"> Nick Wilkins</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Kerr"> Daniel Kerr</a>, <a href="https://publications.waset.org/abstracts/search?q=Zekeriya%20Aliyazicioglu"> Zekeriya Aliyazicioglu</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20K.%20Hwang"> H.

The main results of the study are as follows: First, there was a difference in expectations that the burden of the examinees would decrease as announced by KCUE. Thus, there was still a strain on the university entrance exam after the enforcement of the policy. Second, private tutoring is expanding in different forms, rather than reducing the policy. It is different from the prediction that examinees can prepare for university admissions without the private tutoring. Thus, the college admission rules currently enforced needs to be improved.

Since the building construction works repeatedly in the vertical space, it is relatively easy to confirm the interference effect when applying the BIM, but the interference effect for the civil engineering project is relatively small because the civil works perform non-repetitive processes in the horizontal space. For this reason, it is desirable to apply BIM to the construction phase when applying BIM to the civil engineering project, and the most active BIM tool applied to the construction phase is the 4D CAD function for the schedule management. This paper proposes the application procedure of BIM by the construction phase of civil engineering project and a linear 4D CAD construction methodology suitable for the civil engineering project in which linear work is performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BIM" title="BIM">BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=4D%20CAD" title=" 4D CAD"> 4D CAD</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%204D%20simulation" title=" linear 4D simulation"> linear 4D simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=VR" title=" VR"> VR</a> </p> <a href="https://publications.waset.org/abstracts/83745/bim-application-and-construction-schedule-simulation-for-the-horizontal-work-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83745.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">400</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> An Online Mastery Learning Method Based on a Dynamic Formative Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeongim%20Kang">Jeongim Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Moon%20Hee%20Kim"> Moon Hee Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Baeg%20Kim"> Seong Baeg Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a novel e-learning model that is based on a dynamic formative evaluation.

The dynamic formative evaluation proposed is able to supplement limitation of the existing approaches. Since a repetitive learning method does not provide a perfect feedback, this paper puts an emphasis on the dynamic formative evaluation that is able to maximize learning achievement. Through the dynamic formative evaluation, the instructor is able to refer to the evaluation result when making estimation about the learner.

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.

Here we report design, fabrication and validating of a micro-machined Coulter counter device with multiple-channel to realize such application for low cost. Multiple vertical through-holes were fabricated on a silicon chip, combined with the PDMS micro-fluidics channel that serves as the sensing channel. In order to avoid the crosstalk introduced by the electrical connection, instead of measuring the current passing through, the potential of each channel is monitored, thus the high throughput is possible. A peak of the output potential can be captured when the cell/particle is passing through the microhole. The device was validated by counting and sizing the polystyrene beads with diameter of 6 μm, 10 μm and 15 μm. With the sampling frequency to be set at 100 kHz, up to 5000 counts/sec for each channel can be realized. The counting and enumeration of MCF7 cancer cells are also demonstrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Coulter%20counter" title="Coulter counter">Coulter counter</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20enumeration" title=" cell enumeration"> cell enumeration</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20through-put" title=" high through-put"> high through-put</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20sizing" title=" cell sizing"> cell sizing</a> </p> <a href="https://publications.waset.org/abstracts/12788/multiple-channel-coulter-counter-for-cell-sizing-and-enumeration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12788.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">610</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> Development of Visual Element Design Guidelines for Consumer Products Based on User Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taezoon%20Park">Taezoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Wonil%20Hwang"> Wonil Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to build a design guideline for the effective visual display used for consumer products considering user characteristics; gender and age.

Visual design elements commonly used for consumer product, were selected and appropriate guidelines were developed based on the experimental result. Since the provided data with case example suggests a feasible design space, it will save time for a product designer to find appropriate design alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20guideline" title="design guideline">design guideline</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20product" title=" consumer product"> consumer product</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20design%20element" title=" visual design element"> visual design element</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20perception" title=" visual perception"> visual perception</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20design" title=" emotional design"> emotional design</a> </p> <a href="https://publications.waset.org/abstracts/55080/development-of-visual-element-design-guidelines-for-consumer-products-based-on-user-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55080.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">128</span> A Study on Optimum Shape in According to Equivalent Stress Distributions at the Die and Plug in the Multi-Pass Drawing Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yeon-Jong%20Jeong">Yeon-Jong Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mok-Tan%20Ahn"> Mok-Tan Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Seok-Hyeon%20Park"> Seok-Hyeon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Hun%20Ha"> Seong-Hun Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon-Hong%20Park"> Joon-Hong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Bae%20Park"> Jong-Bae Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multi-stage drawing process is an important technique for forming a shape that cannot be molded in a single process. multi-stage drawing process in number of passes and the shape of the die are an important factors influencing the productivity and formability of the product. The number and shape of the multi-path in the mold of the drawing process is very influencing the productivity and formability of the product. Half angle of the die and mandrel affects the drawing force and it also affects the completion of the final shape. Thus reducing the number of pass and the die shape optimization are necessary to improve the formability of the billet. Analyzing the load on the die through the FEM analysis and in consideration of the formability of the material presents a die model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-pass%20shape%20drawing" title="multi-pass shape drawing">multi-pass shape drawing</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20stress" title=" equivalent stress"> equivalent stress</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20shape" title=" optimum shape"> optimum shape</a> </p> <a href="https://publications.waset.org/abstracts/60708/a-study-on-optimum-shape-in-according-to-equivalent-stress-distributions-at-the-die-and-plug-in-the-multi-pass-drawing-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60708.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">479</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> EEG Signal Processing Methods to Differentiate Mental States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20H.%20Hwang">Sun H.

EOG is the most distinct interfering signal when EEG signals are measured and analyzed. It is very important how to process raw EEG signals in order to obtain useful information. In this study, the EEG signal processing techniques such as EOG filtering and outlier removal were examined to minimize unwanted EOG signals and other noises. The two different mental states of resting and focusing were examined through EEG analysis. A focused state was induced by letting subjects to watch a red dot on the white screen. EEG data for 32 healthy subjects were measured. EEG data after 60-Hz notch filtering were processed by a commercially available EOG filtering and our presented algorithm based on the removal of outliers. The ratio of beta wave to theta wave was used as a parameter for determining the degree of focusing. The results show that our algorithm was more appropriate than the existing EOG filtering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG" title="EEG">EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=focus" title=" focus"> focus</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20state" title=" mental state"> mental state</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier" title=" outlier"> outlier</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a> </p> <a href="https://publications.waset.org/abstracts/62057/eeg-signal-processing-methods-to-differentiate-mental-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62057.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">283</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">126</span> Shape Optimization of a Hole for Water Jetting in a Spudcan for a Jack-Up Rig</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han%20Ik%20Park">Han Ik Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Hyeon%20Seong"> Jeong Hyeon Seong</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Seop%20Han"> Dong Seop Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-Chul%20Shin"> Su-Chul Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Chul%20Park"> Young Chul Park </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Spudcan is mounted on the lower leg of the jack-up rig, a device for preventing a rollover of a structure and to support the structure in a stable sea floor. At the time of inserting the surface of the spud can to penetrate when the sand layer is stable and smoothly pulled to the clay layer, and at that time of recovery when uploading the spud can is equipped with a water injection device. In this study, it is significant to optimize the shape of pipelines holes for water injection device and it was set in two kinds of shape, the oval and round. Interpretation of the subject into the site of Gulf of Mexico offshore Wind Turbine Installation Vessels (WTIV)was chosen as a target platform. Using the ANSYS Workbench commercial programs, optimal design was conducted. The results of this study can be applied to the hole-shaped design of various marine structures. <p class="card-text"><strong>Keywords:</strong> <a
