pocket-sized, and carriable on the users. To serve these requirements, we developed the SiPM-based portable radiation detectors. The prototype uses a Ce:GAGG scintillator coupled to a silicon photomultiplier and a radio frequency(RF) module to measure gamma-ray, and can be accessed wirelessly or remotely by mobile equipment. The prototype device consumes roughly 4.4W, weighs about 180g (including battery), and measures 5.0 7.0.

Likewise, the Licca-chan, a Japanese doll created in 1967, also became a Japanese symbolic doll of Japanese society. Prior to the introduction of Licca-chan, Barbie was already marketed in Japan but their sales were dismal. Licca-chan (an actual name: Kayama Licca) is a plastic doll with a variety of sizes ranging from 21.0 cm to 29.0 cm which many Japanese girls dream of having. For over 35 years, the manufacturer, Takara Co., Ltd. has sold over 48 million dolls and has produced doll houses, accessories, clothes, and Licca-chan video games for the Nintendo DS. Many First-generation Licca-chan consumers still are enamored with Licca-chan, and go to Licca-chan House, in an amusement park with their daughters. These people are called Licca-chan maniacs, as they enjoy touring the Licca-chan’s factory in Tohoku or purchase various Licca-chan accessories. After the successful launch of Licca-chan into the Japanese market, a mixed-like doll from the US and Japan, a doll, JeNny, was later sold in the same Japanese market by Takara Co., Ltd. in 1982. Comparison of these cultural iconic dolls, Barbie and Licca-chan, are analyzed in this paper. In fact, these dolls have concepts of girls’ dreams. By using concepts of mythology of Jean Baudrillard, these dolls can be represented idealized images of figures in the products for consumers, but at the same time, consumers can see products with different perspectives, which can cause controversy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barbie" title="Barbie">Barbie</a>, <a href="https://publications.waset.org/abstracts/search?q=dolls" title=" dolls"> dolls</a>, <a href="https://publications.waset.org/abstracts/search?q=JeNny" title=" JeNny"> JeNny</a>, <a href="https://publications.waset.org/abstracts/search?q=idealization" title=" idealization"> idealization</a>, <a href="https://publications.waset.org/abstracts/search?q=Licca-chan" title=" Licca-chan"> Licca-chan</a> </p> <a href="https://publications.waset.org/abstracts/8507/idealization-of-licca-chan-and-barbie-comparison-of-two-dolls-across-the-pacific" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8507.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">271</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">1181</span> Study on Filter for Semiconductor of Minimizing Damage by X-Ray Laminography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chan%20Jong%20Park">Chan Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Min%20Park"> Hye Min Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Ho%20Kim"> Jeong Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki%20Hyun%20Park"> Ki Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Koan%20Sik%20Joo"> Koan Sik Joo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research used the MCNPX simulation program to evaluate the utility of a filter that was developed to minimize the damage to a semiconductor device during defect testing with X-ray. The X-ray generator was designed using the MCNPX code, and the X-ray absorption spectrum of the semiconductor device was obtained based on the designed X-ray generator code. To evaluate the utility of the filter, the X-ray absorption rates of the semiconductor device were calculated and compared for Ag, Rh, Mo and V filters with thicknesses of 25μm, 50μm, and 75μm. The results showed that the X-ray absorption rate varied with the type and thickness of the filter, ranging from 8.74% to 49.28%. The Rh filter showed the highest X-ray absorption rates of 29.8%, 15.18% and 8.74% for the above-mentioned filter thicknesses. As shown above, the characteristics of the X-ray absorption with respect to the type and thickness of the filter were identified using MCNPX simulation. With these results, both time and expense could be saved in the production of the desired filter. In the future, this filter will be produced, and its performance will be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-ray" title="X-ray">X-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNPX" title=" MCNPX"> MCNPX</a>, <a href="https://publications.waset.org/abstracts/search?q=filter" title=" filter"> filter</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor" title=" semiconductor"> semiconductor</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a> </p> <a href="https://publications.waset.org/abstracts/53350/study-on-filter-for-semiconductor-of-minimizing-damage-by-x-ray-laminography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53350.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">424</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">1180</span> Study on Beta-Ray Detection System in Water Using a MCNP Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ki%20Hyun%20Park">Ki Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Min%20Park"> Hye Min Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Ho%20Kim"> Jeong Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chan%20Jong%20Park"> Chan Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Koan%20Sik%20Joo"> Koan Sik Joo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the modern days, the use of radioactive substances is on the rise in the areas like chemical weaponry, industrial usage, and power plants. Although there are various technologies available to detect and monitor radioactive substances in the air, the technologies to detect underwater radioactive substances are scarce. In this study, computer simulation of the underwater detection system measuring beta-ray, a radioactive substance, has been done through MCNP. CaF₂, YAP(Ce) and YAG(Ce) have been used in the computer simulation to detect beta-ray as scintillator. Also, the source used in the computer simulation is Sr-90 and Y-90, both of them emitting only pure beta-ray. The distance between the source and the detector was shifted from 1mm to 10mm by 1 mm in the computer simulation. The result indicated that Sr-90 was impossible to measure below 1 mm since its emission energy is low while Y-90 was able to be measured up to 10mm underwater. In addition, the detector designed with CaF₂ had the highest efficiency among 3 scintillators used in the computer simulation. Since it was possible to verify the detectable range and the detection efficiency according to modeling through MCNP simulation, it is expected that such result will reduce the time and cost in building the actual beta-ray detector and evaluating its performances, thereby contributing the research and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beta-ray" title="Beta-ray">Beta-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=CaF%E2%82%82" title=" CaF₂"> CaF₂</a>, <a href="https://publications.waset.org/abstracts/search?q=detector" title=" detector"> detector</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNP%20simulation" title=" MCNP simulation"> MCNP simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=scintillator" title=" scintillator"> scintillator</a> </p> <a href="https://publications.waset.org/abstracts/53352/study-on-beta-ray-detection-system-in-water-using-a-mcnp-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">510</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1179</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.

We also analyze the design factors that can affect the accuracy of DOA estimation through simulation, and proceed with further consideration on how to apply the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DOA%20estimation" title="DOA estimation">DOA estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=MUSIC%20algorithm" title=" MUSIC algorithm"> MUSIC algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20spectrum" title=" spatial spectrum"> spatial spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=array%20signal%20processing" title=" array signal processing"> array signal processing</a> </p> <a href="https://publications.waset.org/abstracts/88658/simulation-of-3-d-direction-of-arrival-estimation-using-music-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88658.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">379</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">1175</span> Pervaporation of Dimethyl Carbonate / Methanol / Water Mixtures Using Zeolite Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Ho%20Moon">Jong-Ho Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Ho%20Lee"> Dong-Ho Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyunuk%20Kim"> Hyunuk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Cheol%20Park"> Young Cheol Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Seop%20Lee"> Jong-Seop Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-deok%20Jeon"> Jae-deok Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Keun%20Lee"> Hyung-Keun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel membrane reactor process for DMC synthesis from carbon dioxide has been developing in Korea Institute of Energy Research. The scheme of direct synthesis of DMC from CO₂ and Methanol is 'CO₂ + 2MeOH ↔ DMC + H₂O'. Among them, reactants are CO₂ and MeOH, product is DMC, and byproduct is H₂O (water). According to Le Chatelier’s principle, removing byproduct (water) can shift the reaction equilibrium to the right (DMC production). The main purpose of this process is removing water during the reaction. For efficient in situ water removal (dehydration) and DMC separation, zeolite 4A membranes with very small pore diameter and hydrophilicity were introduced. In this study, pervaporation performances of binary and ternary DMC / methanol / water mixtures were evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dimehtyl%20carbonate" title="dimehtyl carbonate">dimehtyl carbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol" title=" methanol"> methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite%20membrane" title=" zeolite membrane"> zeolite membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=pervaporation" title=" pervaporation"> pervaporation</a> </p> <a href="https://publications.waset.org/abstracts/71361/pervaporation-of-dimethyl-carbonate-methanol-water-mixtures-using-zeolite-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71361.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1174</span> Study of Drawing Characteristics due to Friction between the Materials by FEM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Won%20Jin%20Ryu">Won Jin Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mok%20Tan%20Ahn"> Mok Tan Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeok%20Choi"> Hyeok Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Hong%20Park"> Joon Hong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Min%20Kim"> Sung Min Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Bae%20Park"> Jong Bae Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pipes for offshore plants require specifications that satisfy both high strength and high corrosion resistance.

Furthermore, the tilting bearing has many advantages such as high stability at high-speed performance, long life, high damping, high impact resistance and low noise. Therefore, it mostly used in mid to large size turbomachines, despite the high price disadvantage. Recently, manufacture and process employing laser techniques advancing at a fast-growing rate in mechanical industry, the dissimilar metal weld process employing laser techniques is actively studied. Moreover, also, Industry fields try to apply for welding the white metal and the back metal using laser cladding method for high durability. Furthermore, it has followed that laser cladding method has a lot better bond strength, toughness, anti-abrasion and environment-friendly than centrifugal casting method through preceding research. Therefore, the laser cladding method has a lot better quality, cost reduction, eco-friendliness and permanence of technology than the centrifugal casting method or the gravity casting method. In this study, we compare the mechanical properties of different bearing materials by evaluating the behavior of laser cladding layer with various materials (i.e. SS400, SCM440, S20C) under the same parameters. Furthermore, we analyze the porosity of various tilting pad bearing materials which white metal treated on samples. SEM, EDS analysis and hardness tests of three materials are shown to understand the mechanical properties and tribological behavior.

In the industry field, bearing durability is improved by surface treatment on the bearing surface by centrifugal casting or gravity casting production method. However, this manufacturing method has caused problems such as long processing time, defect rate, and health harmful effect. To solve this problem, there is a laser cladding deposition treatment, which provides fast processing and food adhesion. Therefore, optimum conditions of white metal laser deposition should be studied to minimize bearing contact axis wear using laser cladding techniques. In this study, we deposit a soft white metal layer on SCM440, which is mainly used for shaft and bolt. On laser deposition process, the laser power and powder feed rate and laser head speed factors are controlled to find out the optimal conditions. We also measure hardness using micro Vickers, analyze FE-SEM (Field Emission Scanning Electron Microscope) and EDS (Energy Dispersive Spectroscopy) to study the mechanical properties and surface characteristics with various parameters change. Furthermore, this paper suggests the optimum condition of laser cladding deposition to apply in industrial fields.

In this study on hybrid joints, quasi-static experiments and finite element analysis were performed to investigate the failure mechanism of hybrid composite joint with respect to the joint properties such as the adhesive material, clamping force, and joint geometry. The outcomes demonstrated that the stiffness of the adhesive is the most imperative design parameter. In this investigation, two adhesives with various stiffness values were utilized. Regarding the joints utilizing the adhesive with the lower stiffness modulus, it was observed that the load was exchanged promptly through the adhesive since it was shared more proficiently between the bolt and adhesive. This phenomenon permitted the hybrid joints with low-modulus adhesive to support more prominent loads before failure when contrasted with the joints that utilize the stiffer adhesive. In the next step, the stress share between the bond and bolt as a function of various design parameters was studied using a finite element model in which it was understood that the geometrical parameters such as joint overlap and width have a significant influence on the load sharing between the bolt and the adhesive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20joints" title="composite joints">composite joints</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20joints" title=" hybrid joints"> hybrid joints</a>, <a href="https://publications.waset.org/abstracts/search?q=single-lap%20joint" title=" single-lap joint"> single-lap joint</a> </p> <a href="https://publications.waset.org/abstracts/85844/studying-the-load-sharing-and-failure-mechanism-of-hybrid-composite-joints-using-experiment-and-finite-element-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85844.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">406</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">1168</span> Optimal Rotor Design of an 150kW-Class IPMSM through the 3D Voltage-Inductance Map Analysis Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eung-Seok%20Park">Eung-Seok Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Chul%20Jeong"> Tae-Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jong%20Park"> Hyun-Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jun"> Hyun-Woo Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Woo%20Kang"> Dong-Woo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presents a methodology to determine detail design directions of an 150kW-class IPMSM (interior permanent magnet synchronous motor) and its detail design.

One of the key applications is to recognize the user location by indoor illuminators such as light emitting diodes. For localization of individual receivers in these systems, we usually assume that receivers and transmitters are placed in parallel. However, it is difficult to satisfy this assumption because the receivers move randomly in real case. It is necessary to analyze the case when transmitter is not placed perfectly parallel to receiver. It is also important to identify changes on optical gain by the tilted angles and distances of them against the illuminators. In this paper, we simulate optical gain for various cases where the tilt of the receiver and the distance change. Then, we identified changing patterns of optical gains according to tilted angles of a receiver and distance. These results can help many VLC applications understand the extent of the location errors with regard to optical gains of the receivers and identify the root cause. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visible%20light%20communication" title="visible light communication">visible light communication</a>, <a href="https://publications.waset.org/abstracts/search?q=incident%20angle" title=" incident angle"> incident angle</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20gain" title=" optical gain"> optical gain</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20emitting%20diode" title=" light emitting diode"> light emitting diode</a> </p> <a href="https://publications.waset.org/abstracts/60436/effects-of-incident-angle-and-distance-on-visible-light-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60436.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">335</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">1166</span> Single Event Transient Tolerance Analysis in 8051 Microprocessor Using Scan Chain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Sung%20Go">Jun Sung Go</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Kang%20Park"> Jong Kang Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Tae%20Kim"> Jong Tae Kim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> As semi-conductor manufacturing technology evolves; the single event transient problem becomes more significant issue. Single event transient has a critical impact on both combinational and sequential logic circuits, so it is important to evaluate the soft error tolerance of the circuits at the design stage. In this paper, we present a soft error detecting simulation using scan chain. The simulation model generates a single event transient randomly in the circuit, and detects the soft error during the execution of the test patterns. We verified this model by inserting a scan chain in an 8051 microprocessor using 65 nm CMOS technology. While the test patterns generated by ATPG program are passing through the scan chain, we insert a single event transient and detect the number of soft errors per sub-module. The experiments show that the soft error rates per cell area of the SFR module is 277% larger than other modules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scan%20chain" title="scan chain">scan chain</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20event%20transient" title=" single event transient"> single event transient</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20error" title=" soft error"> soft error</a>, <a href="https://publications.waset.org/abstracts/search?q=8051%20processor" title=" 8051 processor"> 8051 processor</a> </p> <a href="https://publications.waset.org/abstracts/60435/single-event-transient-tolerance-analysis-in-8051-microprocessor-using-scan-chain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60435.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1165</span> Integrated Simulation and Optimization for Carbon Capture and Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taekyoon%20Park">Taekyoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokgoo%20Lee"> Seokgoo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungho%20Kim"> Sungho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ung%20Lee"> Ung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chonghun%20Han"> Chonghun Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO2 capture and storage/sequestration (CCS) is a key technology for addressing the global warming issue.

The efficacy of prophylactic remifentanil, one of mu opioid agonist, in preventing EA is controversial. This meta-analysis assessed the effectiveness of remifentanil to decrease the incidence of EA from sevoflurane anesthesia in children. We searched for randomized controlled trials comparing sevoflurane alone anesthesia with sevoflurane and remifentanil anesthesia to prevent EA in the Cochrane Library, Embase, Pubmed, and KoreaMed, and included 6 studies with 361 patients. The number of patients of reporting EA was summarized using risk ratio (RR) with 95% confidence interval (CI), with point estimates and 95CIs derived from a random effects Mantel-Haenszel method. Overall incidence of EA was about 41%. Compared with sevoflurane alone anesthesia, intravenous infusion of remifentanil with sevoflurane significantly reduced the incidence of EA (RR 0.53, 95% CI 0.39-0.73, P < 0.0001), (heterogeneity, I2 = 0, P = 0.42). This meta-analysis suggested that continuous infusion of remifentanil could be effective in decreasing the EA of about 47% after sevoflurane anesthesia. However, considering limitations of the included studies, more randomized controlled studies are required to verify our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergence%20agitation" title="emergence agitation">emergence agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=remifentanil" title=" remifentanil"> remifentanil</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a> </p> <a href="https://publications.waset.org/abstracts/76607/the-effect-of-remifentanil-on-emergence-agitation-after-sevoflurane-anesthesia-in-children-a-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76607.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">376</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">1163</span> A Study on Improvement of Performance of Anti-Splash Device for Cargo Oil Tank Vent Pipe Using CFD Simulation and Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min-Woo%20Kim">Min-Woo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ok-Kyun%20Na"> Ok-Kyun Na</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Ho%20Byun"> Jun-Ho Byun</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Hwan%20Park"> Jong-Hwan Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Hwa%20Yang"> Seung-Hwa Yang</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=Young-Chul%20Park"> Young-Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is focused on the comparative analysis and improvement to grasp the flow characteristic of the Anti-Splash Device located under the P/V Valve and new concept design models using the CFD analysis and Artificial Neural Network.

The Rogue waves, which are also known as big waves, freak waves, extreme waves, monster waves, focused waves, giant waves and abnormal waves, are unexpected and suddenly appearing, and can have a breaking force to destroy the structure even though modern structures are designed to tolerate a breaking wave. In the present study, a series of focused waves are numerically reproduced by concentrating nonlinear multi-directional waves into a target point using a commercial CFD software, Star-CCM+. A flow analysis for investigating the physical characteristics of the focused waves is performed using the Star-CCM+, while it has several difficulties to examine the inner properties of the waves in existing potential theory and experiments.

In contrast to the deepening concerns, measurement tools that can assess the vulnerability of cyber violence in individual youths still need to be supplemented. The measurement tools lack consideration of various factors related to cyber violence among youths. Most of the tools are self-report questionnaires, and these adolescents' self-report questionnaire forms can underestimate the harmful behavior and overestimate the damage experience. Therefore, this study aims to develop a multi-report measurement tool for youths that can reliably measure individuals' ecological factors related to cyber violence. The literature review explored factors related to cyber violence, and the questions were constructed. The face validity of the questions was confirmed by conducting focus group interviews. Exploratory and confirmatory factor analyses (N=671) were also conducted for statistical validation. This study developed a multi-report measurement tool for cyber violence with 161 questions, consisting of six domains: online behavior, cyber violence awareness, victimization-perpetration-witness experience, coping efficacy (individuals, peers, teachers, and parents), psychological characteristics, and pro-social capabilities. In addition to self-report from a youth respondent, this measurement tool includes peers, teachers, and parents reporting for the respondent. It is possible to reliably measure the ecological factors of individual youths who are vulnerable or highly resistant to cyber violence. In schools, teachers could refer to the measurement results for guiding students, better understanding their cyber violence conditions, and assessing their pro-social capabilities. With the measurement results, teachers and police officers could detect perpetrators or victims and intervene immediately. In addition, this measurement tool could analyze the effects of the prevention and intervention programs for cyber violence and draw appropriate suggestions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescents" title="adolescents">adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20violence" title=" cyber violence"> cyber violence</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20violence%20measurement%20tool" title=" cyber violence measurement tool"> cyber violence measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20tool" title=" measurement tool"> measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-report%20measurement%20tool" title=" multi-report measurement tool"> multi-report measurement tool</a>, <a href="https://publications.waset.org/abstracts/search?q=youths" title=" youths"> youths</a> </p> <a href="https://publications.waset.org/abstracts/155962/the-development-of-a-cyber-violence-measurement-tool-for-youths-a-multi-reporting-of-ecological-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155962.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">101</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">1158</span> Appraising the Need to Improve Sumu Wildlife Park Bauchi, North-Eastern Nigeria to International Standard </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanusi%20Abubakar%20Sadiq">Sanusi Abubakar Sadiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20William%20Chiwar"> Rebecca William Chiwar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wildlife Park stands a chance of contributing to tourism development in different ways, but available infrastructure, and facilities required by visitors when they arrive, access road to the destination, and resources to facilitate positive experience are lacking in certain areas. The study set out to find out the need to develop Sumu Wildlife Park Bauchi State, to an international standard. The study focused on identifying the existing facilities and infrastructure at the park and to further identify the available resources used by visitors. In attempt to find out the impact of developing Sumu Wildlife Park and ways of filling the gap of the actual standard data were obtained from fifteen administrative staff of Sumu Wildlife Park, ten staff of Bauchi state Tourism Board and twenty-five residents of the community in Kafin Madaki, Bauchi. Relevant literature were reviewed in the study; data collected were organized and analyzed using Statistical Package of Social Sciences (SPSS), software for analysis. Findings revealed that though Sumu Wildlife Park has attractions to keep visitors patronage but has insufficient facilities to maintain visitors and has not been developed to an expected standard. The problem faced by the management of Sumu wildlife Park is lack of adequate facilities, infrastructure and resources. The need to develop Sumu Wildlife Park has enormous benefits in increasing patronage. Provision of more funds would help improve standard as there would be more activities within and around the park. Regular maintenance of those facilities protects the life span of the park. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attractions" title="attractions">attractions</a>, <a href="https://publications.waset.org/abstracts/search?q=facilities" title=" facilities"> facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a> </p> <a href="https://publications.waset.org/abstracts/51201/appraising-the-need-to-improve-sumu-wildlife-park-bauchi-north-eastern-nigeria-to-international-standard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51201.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">385</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">1157</span> Chemical Stability of Ceramic Crucibles to Molten Titanium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Min%20Park">Jong-Min Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Ki%20Park"> Hyung-Ki Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seok%20Hong%20Min"> Seok Hong Min</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Titanium is widely used due to its high specific strength, good biocompatibility, and excellent corrosion resistance. In order to produce titanium powders, it is necessary to melt titanium, and generally it is conducted by an induction heating method using Al₂O₃ ceramic crucible. However, since titanium reacts chemically with Al₂O₃, it is difficult to melt titanium by the induction heating method using Al₂O₃ crucible. To avoid this problem, we studied the chemical stability of the various crucibles such as Al₂O₃, MgO, ZrO₂, and Y₂O₃ crucibles to molten titanium. After titanium lumps (Grade 2, O(oxygen)<0.25wt%) were placed in each crucible, they were heated to 1800℃ with a heating rate of 5 ℃/min, held at 1800℃ for 30 min, and finally cooled to room temperature with a cooling rate of 5 ℃/min. All heat treatments were carried out in high purity Ar atmosphere. To evaluate the chemical stability, thermodynamic data such as Ellingham diagram were utilized, and also Vickers hardness test, microstructure analysis, and EPMA quantitative analysis were performed. As a result, Al₂O₃, MgO and ZrO₂ crucibles chemically reacted with molten titanium, but Y₂O₃ crucible rarely reacted with it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium" title="titanium">titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20melting" title=" induction melting"> induction melting</a>, <a href="https://publications.waset.org/abstracts/search?q=crucible" title=" crucible"> crucible</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20stability" title=" chemical stability"> chemical stability</a> </p> <a href="https://publications.waset.org/abstracts/77805/chemical-stability-of-ceramic-crucibles-to-molten-titanium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77805.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">301</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">1156</span> Economic Valuation of Environmental Services Sustained by Flamboyant Park in Goiania-Go, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brenda%20R.%20Berca">Brenda R.

The Flamboyant Park is one of the most relevant urban parks, and it is located near a stadium, a shopping center, and two supercenters. In order to define the methods used for the valuation of Flamboyant Park, the first step was carrying out bibliographical research with the view to better understand which method is most feasible to valuate the Park. Thus, the following direct methods were selected: travel cost, hedonic pricing, and contingent valuation. In addition, an indirect method (replacement cost) was applied at Flamboyant Park. The second step was creating and applying two surveys. The first survey aimed at the visitors of the park, addressing socio-economic issues, the use of the Park, as well as its importance and the willingness the visitors, had to pay for its existence. The second survey was destined to the existing trade in the Park, in order to collect data regarding the profits obtained by them. In the end, the characterization of the profile of the visitors and the application of the methods of contingent valuation, travel cost, replacement cost and hedonic pricing were obtained, thus monetarily valuing the various ecosystem services sustained by the park. Some services were not valued due to difficulties encountered during the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contingent%20valuation" title="contingent valuation">contingent valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20services" title=" ecosystem services"> ecosystem services</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20environmental%20valuation" title=" economic environmental valuation"> economic environmental valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=hedonic%20pricing" title=" hedonic pricing"> hedonic pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20cost" title=" travel cost"> travel cost</a> </p> <a href="https://publications.waset.org/abstracts/109560/economic-valuation-of-environmental-services-sustained-by-flamboyant-park-in-goiania-go-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109560.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">226</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">1155</span> A Descriptive Preference Analysis on Waterfront Parks Neighboring Lake Shihwa </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Ahn">J.

Each development project includes a plan on utilizing waterfront areas, but there exist a difference on waterfront design criteria between experts and users. Therefore, it is significant to analyze preferences in design elements of existing waterfront parks around Lake Shihwa (Ansan Waterfront Park, Shihwa Reed Wetland Park, and T-Light Park) based on users’ perspectives and to reflect the result on upcoming waterfront developments. This study derives design elements on waterfront parks from literature reviews. The survey questionnaires are created based on these classified elements and the surveys are conducted to experts and users with in-depth interviews. For all three parks, several park facilities appear to be not recognized by users. Therefore, the circulation path should be introduced in guide maps and information activities and furthermore in disposition of park facilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20elements" title="design elements">design elements</a>, <a href="https://publications.waset.org/abstracts/search?q=lake%20Shihwa" title=" lake Shihwa"> lake Shihwa</a>, <a href="https://publications.waset.org/abstracts/search?q=preference" title=" preference"> preference</a>, <a href="https://publications.waset.org/abstracts/search?q=waterfront%20park" title=" waterfront park "> waterfront park </a> </p> <a href="https://publications.waset.org/abstracts/3638/a-descriptive-preference-analysis-on-waterfront-parks-neighboring-lake-shihwa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3638.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">457</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">1154</span> Evaluation of Japanese Kyoto Park in Terms of User Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruhug%C3%BCl%20%C3%96zge%20Gemici">Ruhugül Özge Gemici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The need for open space, which is an important problem especially since the 19th century, has become more important in today's conditions. The most important factor in increasing the livability of cities is the open and green areas. Parks are the most important of the urban open and green space elements that provide the most benefit to users. In this context, the user satisfaction of the Japanese Kyoto Park, which is the subject of the research, was evaluated in the light of the questionnaires. With this analysis, the satisfaction level of the user using the park was determined. Suggestions have been developed for the park to be handled and regulated according to the user requests and requirements changing over time. <p class="card-text"><strong>Keywords:</strong> <a
