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">73</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">72</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">71</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 this study, we designed edutainment contents in the form of an adventure game that applies the storytelling method. This content provides questions and items constituted dynamically and reorganized learning contents through analysis of test results. It allows learners to solve various questions through effective iterative learning.

With no synchronizing clock, it is difficult to diagnose an occurrence of permanent or stuck-in faults in the operation of asynchronous machines. In this paper, we present a fault detector comprised of a timer and a set of static functions to determine the occurrence of faults. 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">69</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.

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">62</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. On evaluating the existing format of e-learning, conditions regarding repetitive learning to achieve mastery, causes issues for learners to lose tension and become neglectful of learning. 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.

Data utilized in this study were derived from 306 U.S. Federal court cases of cybercrime. The findings of this study indicated that there was a positive relationship between co-offending and journey-to-cybercrime, whereas there was no link between offender-stranger and journey-to-cybercrime.

Pd catalyst supported on activated carbon having various specific surface area were characterized by BET, XRD and FE-TEM.

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.

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">57</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.

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">56</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.

Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oxide layer of normal Al-Mg alloy can be characterized by upper MgO and lower MgAl2O4 spinel. The formation of the MgO outmost layer occurs by the surface segregation of Mg in the initial oxidation. After then, the oxidation is proceeded with the formation of MgA12O4 spinel beneath the MgO. Growth of the oxide layer is accelerated by constant formation of MgA12O4 spinel. On the other hand, the oxidation resistance of Al-Mg alloys can be significantly improved simply by Mg+Al2Ca master alloy use as the Mg alloying element and such an improvement is attributed to the CaO/MgO mixed layer. Al-Mg alloy containing Al2Ca shows CaO as the upper layer and MgO as the lower one without MgA12O4 spinel. Such a dense oxide film acts as a protective layer. However, the CaO/MgO scale has the outmost MgO, partly, after a long time exposure to a harsh oxidation condition. The aim of this study is to investigate the inter-filling behaviour of CaO and MgO mixed layer in oxidation resistance mechanism of Al-Mg alloys containing Al2Ca. The process of outmost MgO layer formation will be clarified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Mg%20alloy" title="Al-Mg alloy">Al-Mg alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=Al2Ca" title=" Al2Ca"> Al2Ca</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation" title=" oxidation"> oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=MgO" title=" MgO"> MgO</a> </p> <a href="https://publications.waset.org/abstracts/49097/inter-filling-of-cao-and-mgo-mixed-layer-in-surface-behavior-of-al-mg-alloys-containing-al2ca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49097.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">54</span> Optimization of Urea Water Solution Injector for NH3 Uniformity Improvement in Urea-SCR System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyoungwoo%20Park">Kyoungwoo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Gil%20Dong%20Kim"> Gil Dong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Joon%20Moon"> Seong Joon Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Kil%20Lee"> Ho Kil Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Urea-SCR is one of the most efficient technologies to reduce NOx emissions in diesel engines. In the present work, the computational prediction of internal flow and spray characteristics in the Urea-SCR system was carried out by using 3D-CFD simulation to evaluate NH3 uniformity index (NH3 UI) and its activation time according to the official New European Driving Cycle (NEDC). The number of nozzle and its diameter, two types of injection directions, and penetration length were chosen as the design variables. The optimal solutions were obtained by coupling the CFD analysis with Taguchi method. The L16 orthogonal array and small-the-better characteristics of the Taguchi method were used, and the optimal values were confirmed to be valid with 95% confidence and 5% significance level through analysis of variance (ANOVA). The results show that the optimal solutions for the NH3 UI and activation time (NH3 UI 0.22) are obtained by 0.41 and 0,125 second, respectively, and their values are improved by 85.0% and 10.7%, respectively, compared with those of the base model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=NH3%20uniformity%20index" title=" NH3 uniformity index"> NH3 uniformity index</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=Urea-SCR%20system" title=" Urea-SCR system"> Urea-SCR system</a>, <a href="https://publications.waset.org/abstracts/search?q=UWS%20injector" title=" UWS injector"> UWS injector</a> </p> <a href="https://publications.waset.org/abstracts/53096/optimization-of-urea-water-solution-injector-for-nh3-uniformity-improvement-in-urea-scr-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53096.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">267</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">53</span> Wind Fragility for Soundproof Wall with the Variation of Section Shape of Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seong%20Do%20Kim">Seong Do Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung"> Woo Young Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, damages due to typhoons and strong wind are on the rise.

Generally, a single-material pad used for insulation has a heavyweight impact sound level of 44~47 dB with 210 mm thickness slab.

Many workers on construction sites are suffering from extended exposure to stressful situations such as poor and hazardous work environments and task complexity. Stress can be commonly defined as a feeling of emotional or physical tension, which can easily impact construction safety and result in a higher rate of job-related injuries in the construction industry. Physiological signals transmitted from wearable biosensors can be used to detect excessive stress. Therefore, workers’ stress should be detected and mitigated to prevent any type of serious incident or accident proactively. By doing this, construction productivity, as well as job satisfaction, would also be improved in the construction industry. To establish a foundation in this field of research, a conceptual framework for using wearable technology for construction safety has been developed for continuous and automatic monitoring of worker’s stress. The conceptual framework will serve as a foothold in future studies on the application of wearable technology for construction safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20safety" title="construction safety">construction safety</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20stress" title=" occupational stress"> occupational stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20monitoring" title=" stress monitoring"> stress monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20biosensors" title=" wearable biosensors"> wearable biosensors</a> </p> <a href="https://publications.waset.org/abstracts/136006/using-wearable-technology-to-monitor-workers-stress-for-construction-safety-a-conceptual-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136006.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">161</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">50</span> Effect of Poly Naphthalene Sulfonate Superplasticizer on Constructibility of Roller-Compacted Concrete Pavement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chamroeun%20Chhorn">Chamroeun Chhorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Jae%20Hong"> Seong Jae Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon-Ho%20Cho"> Yoon-Ho Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Jong%20Lee"> Hyun Jong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Woo%20Lee"> Seung Woo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of Roller-Compacted Concrete Pavement (RCCP) in public and private applications has been increasing steadily in the past few decades due to its cost saving. This eco-concrete pavement shares construction characteristics from asphalt pavement and material characteristics from the conventional concrete pavement. Due to its low binder and water content, the consistency of Roller-Compacted Concrete (RCC) is typically very stiff. Thus, it is crucial to control the consistency of this concrete. Without appropriate consistency, required density may not be achieved in actual construction for RCCP. The purpose of this study is to investigate the effect on Poly Naphtalene Sulfonate (PNS) superplasticizer on the consistency of RCC as well as its compactibility in actual construction. From this study, it was found that PNS superplasticizer can effectively reduce the stiffness of an RCC mixture and maintain it for a sufficient amount of time without compromising its strength properties. Moreover, it was observed from field test specimens that the use of this admixture can also improve the compaction efficiency throughout the whole depth of pavement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roller-compacted%20concrete" title="roller-compacted concrete">roller-compacted concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=consistency" title=" consistency"> consistency</a>, <a href="https://publications.waset.org/abstracts/search?q=compactibility" title=" compactibility"> compactibility</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20naphthalene%20sulfonate%20superplasticizer" title=" poly naphthalene sulfonate superplasticizer"> poly naphthalene sulfonate superplasticizer</a> </p> <a href="https://publications.waset.org/abstracts/54668/effect-of-poly-naphthalene-sulfonate-superplasticizer-on-constructibility-of-roller-compacted-concrete-pavement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54668.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">251</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">49</span> Anti-Melanogenic Effect of Fisetin through Activating Connective Tissue Growth Factor in vivo Mice Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ryeong-Hyeon%20Kim">Ryeong-Hyeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ah-Reum%20%20Lee"> Ah-Reum Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Soo%20Roh"> Seong-Soo Roh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyo-Nam%20Kim"> Gyo-Nam Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Appropriate regulation of melanogenesis is important for the management of skin pigmentation-related disease.

Here, we induced melanogenesis of HRM2 mice (n=7/group) by UVB irradiation for 20 days. UVB-induced HRM2 mice showed that the significantly increased melanin accumulation, however, fisetin treatment (25mg and 50mg/kg of body weight) dose-dependently and significantly inhibits UVB-induced melanogenesis. In line with this, fisetin treatment effectively down-regulated m RNA and expression levels of tyrosinase, TRP2, and MITF.

Most of the clad pipes are produced by hot rolling. However, problems arise due to high product prices and excessive process numbers. Therefore, in this study, the hot drawing process with excellent product cost, process number and productivity is applied. Due to the nature of the drawing process, the shape of the mold greatly influences the formability of the material and the bonding pressure of the two materials because it is a process of drawing the material to the die and reducing the cross-sectional area. Also, in case of hot drawing, if the mold shape is not suitable due to the increased fluidity of the material, it may cause problems such as tearing and stretching. Therefore, in this study, we try to find the shape of the mold which suppresses the occurrence of defects in the hot drawing process and maximizes the bonding pressure between the two materials through the mold shape optimization design by FEM analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clad%20pipe" title="clad pipe">clad pipe</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20drawing" title=" hot drawing"> hot drawing</a>, <a href="https://publications.waset.org/abstracts/search?q=bonding%20pressure" title=" bonding pressure"> bonding pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=mold%20shape" title=" mold shape"> mold shape</a> </p> <a href="https://publications.waset.org/abstracts/77162/optimal-design-of-shape-for-increasing-the-bonding-pressure-drawing-of-hot-clad-pipes-by-finite-element-method-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77162.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">304</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">47</span> Genetic Diversity and Discovery of Unique SNPs in Five Country Cultivars of Sesamum indicum by Next-Generation Sequencing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nam-Kuk%20Kim">Nam-Kuk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Kim"> Jin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Soomin%20Park"> Soomin Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Changhee%20Lee"> Changhee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mijin%20Chu"> Mijin Chu</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Hun%20Lee"> Seong-Hun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we conducted whole genome re-sequencing of 10 cultivars originated from five countries including Korea, China, India, Pakistan and Ethiopia with Sesamum indicum (Zhongzho No. 13) genome as a reference.

Among these variants, 266,051 SNPs were identified as unique to countries. Pakistan and Ethiopia had high densities of SNPs compared to other countries. Three main clusters (cluster 1: Korea, cluster 2: Pakistan and India, cluster 3: Ethiopia and China) were recovered by neighbor-joining analysis using all variants. Interestingly, some variants were detected in DGAT1 (diacylglycerol O-acyltransferase 1) and FADS (fatty acid desaturase) genes, which are known to be related with fatty acid synthesis and metabolism. These results can provide useful information to understand the regional characteristics and develop DNA markers for origin discrimination of sesame. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sesamum%20indicum" title="Sesamum indicum">Sesamum indicum</a>, <a href="https://publications.waset.org/abstracts/search?q=NGS" title=" NGS"> NGS</a>, <a href="https://publications.waset.org/abstracts/search?q=SNP" title=" SNP"> SNP</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20marker" title=" DNA marker"> DNA marker</a> </p> <a href="https://publications.waset.org/abstracts/54776/genetic-diversity-and-discovery-of-unique-snps-in-five-country-cultivars-of-sesamum-indicum-by-next-generation-sequencing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54776.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">327</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">46</span> Nutritive Advantage of Mealworm (Tenebrio molitor) in the Diet of White Shrimp (Litopenaeus vannamei)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae-ho%20Chung">Tae-ho Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Park"> Chul Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Gi-wook%20Shin"> Gi-wook Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Joo-min%20Kim"> Joo-min Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-hyun%20Kim"> Seong-hyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Namjung%20Kim"> Namjung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mealworm (Tenebrio molitor) was evaluated to investigate the effect of partial or total replacement of fish meal in diets for white shrimp, Litopenaeus vannamei. Experimental groups of shrimp with average initial body weight (2.43 ± 0.54 g) were fed each with 4 isonitrogeneous (38% crude protein) diets formulated to include 0, 25, 50 and 100% (diets 1 to 4, respectively) of fish meal substituted with mealworm. After eight weeks of feeding trials, shrimp fed with diet 3 and 4 revealed the highest values for live weight gain(8.01 ± 2.51 and 7.93 ± 1.12), specific growth rates (2.70 ± 1.12 and 2.59 ± 0.51) as well as better feed conversion ratio (2.69 ± 0.09 and 2.72 ± 0.19) compared to the control group with statistically significant manner (p<0.05). Survival range was 98% in all the treatments. An increase in weight gain and other growth associated parameters was observed with higher replacement. These results clearly indicate that 50% and 100% of fish meal protein in shrimp diet can be replaced by mealworm not only without any adverse effect but also the effect of promoting growth performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mealworm" title="mealworm">mealworm</a>, <a href="https://publications.waset.org/abstracts/search?q=Litopenaeus%20vannamei" title=" Litopenaeus vannamei"> Litopenaeus vannamei</a>, <a href="https://publications.waset.org/abstracts/search?q=Tenebrio%20molitor" title=" Tenebrio molitor"> Tenebrio molitor</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20shrimp" title=" white shrimp"> white shrimp</a> </p> <a href="https://publications.waset.org/abstracts/26041/nutritive-advantage-of-mealworm-tenebrio-molitor-in-the-diet-of-white-shrimp-litopenaeus-vannamei" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26041.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">469</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">45</span> Online Topic Model for Broadcasting Contents Using Semantic Correlation Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang-Uk%20Kwak">Chang-Uk Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun-Joong%20Kim"> Sun-Joong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Bae%20Park"> Seong-Bae Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Jo%20Lee"> Sang-Jo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a method of learning topics for broadcasting contents. There are two kinds of texts related to broadcasting contents. One is a broadcasting script which is a series of texts including directions and dialogues. The other is blogposts which possesses relatively abstracted contents, stories and diverse information of broadcasting contents. Although two texts range over similar broadcasting contents, words in blogposts and broadcasting script are different. In order to improve the quality of topics, it needs a method to consider the word difference. In this paper, we introduce a semantic vocabulary expansion method to solve the word difference. We expand topics of the broadcasting script by incorporating the words in blogposts. Each word in blogposts is added to the most semantically correlated topics. We use word2vec to get the semantic correlation between words in blogposts and topics of scripts. The vocabularies of topics are updated and then posterior inference is performed to rearrange the topics. In experiments, we verified that the proposed method can learn more salient topics for broadcasting contents. <p class="card-text"><strong>Keywords:</strong> <a
