Therefore, the signal detection of MIMOOFDM system is important issue. In this paper, efficient iterative VBLAST detection technique is proposed in wireless communication system. The proposed scheme adjusts the number of candidate symbol and iterative scheme based on channel state. According to the simulation result, the proposed scheme has better BER performance than conventional schemes and similar BER performance of the QRD-M with iterative scheme. Moreover complexity of proposed scheme has 50.6 % less than complexity of QRD-M detection with iterative scheme. Therefore the proposed detection scheme can be efficiently used in wireless communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIMO-OFDM" title="MIMO-OFDM">MIMO-OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=V-BLAST" title=" V-BLAST"> V-BLAST</a>, <a href="https://publications.waset.org/abstracts/search?q=QR-decomposition" title=" QR-decomposition"> QR-decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=QRDM" title=" QRDM"> QRDM</a>, <a href="https://publications.waset.org/abstracts/search?q=DFE" title=" DFE"> DFE</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative%20scheme" title=" iterative scheme"> iterative scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20condition" title=" channel condition"> channel condition</a> </p> <a href="https://publications.waset.org/abstracts/3522/efficient-iterative-v-blast-detection-technique-in-wireless-communication-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3522.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">530</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">495</span> Enhanced Energy Powers via Composites of Piezoelectric CH₃NH₃PbI₃ and Flexoelectric Zn-Al:Layered Double Hydroxides (LDH) Nanosheets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soon-Gil%20Yoon">Soon-Gil Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Ju%20Choi"> Min-Ju Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Ho%20Shin"> Sung-Ho Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Junghyo%20Nah"> Junghyo Nah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Seok%20Choi"> Jin-Seok Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-A%20Song"> Hyun-A Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Goeun%20Choi"> Goeun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Ho%20Choy"> Jin-Ho Choy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Layered double hydroxides (LDHs) with positively charged brucite-like layers and negatively charged interlayer anions are considered a critical nanoscale building block with potential for application in catalysts, biological sensors, and optical, electrical, and magnetic devices. LDHs also have a great potential as an energy conversion device, a key component in common modern electronics. Although LDHs are theoretically predicted to be centrosymmetric, we report here the first observations of the flexoelectric nature of LDHs and demonstrate their potential as an effective energy conversion material. We clearly show a linear energy conversion relationship between the output powers and curvature radius via bending with both the LDH nanosheets and thin films, revealing a direct evidence for flexoelectric effects. These findings potentially open up avenues to incorporate a flexoelectric coupling phenomenon into centrosymmetric materials such as LDHs and to harvest high-power energy using LDH nanosheets. In the present study, for enhancement of the output power, Zn-Al:LDH nanosheets were composited with piezoelectric CH3NH3PbI3 (MAPbI3) dye films and their enhanced energy harvesting was demonstrated in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layered%20double%20hydroxides" title="layered double hydroxides">layered double hydroxides</a>, <a href="https://publications.waset.org/abstracts/search?q=flexoelectric" title=" flexoelectric"> flexoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric" title=" piezoelectric"> piezoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20harvesting" title=" energy harvesting "> energy harvesting </a> </p> <a href="https://publications.waset.org/abstracts/60228/enhanced-energy-powers-via-composites-of-piezoelectric-ch3nh3pbi3-and-flexoelectric-zn-allayered-double-hydroxides-ldh-nanosheets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60228.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">492</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">494</span> An Experimental Study on the Optimum Installation of Fire Detector for Early Stage Fire Detecting in Rack-Type Warehouses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ki%20Ok%20Choi">Ki Ok Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Ho%20Hong"> Sung Ho Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Suck%20Kim"> Dong Suck Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Don%20Mook%20Choi"> Don Mook Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rack type warehouses are different from general buildings in the kinds, amount, and arrangement of stored goods, so the fire risk of rack type warehouses is different from those buildings. The fire pattern of rack type warehouses is different in combustion characteristic and storing condition of stored goods. The initial fire burning rate is different in the surface condition of materials, but the running time of fire is closely related with the kinds of stored materials and stored conditions. The stored goods of the warehouse are consisted of diverse combustibles, combustible liquid, and so on. Fire detection time may be delayed because the residents are less than office and commercial buildings. If fire detectors installed in rack type warehouses are inadaptable, the fire of the warehouse may be the great fire because of delaying of fire detection. In this paper, we studied what kinds of fire detectors are optimized in early detecting of rack type warehouse fire by real-scale fire tests. The fire detectors used in the tests are rate of rise type, fixed type, photo electric type, and aspirating type detectors. We considered optimum fire detecting method in rack type warehouses suggested by the response characteristic and comparative analysis of the fire detectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20detector" title="fire detector">fire detector</a>, <a href="https://publications.waset.org/abstracts/search?q=rack" title=" rack"> rack</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20characteristic" title=" response characteristic"> response characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=warehouse" title=" warehouse"> warehouse</a> </p> <a href="https://publications.waset.org/abstracts/56376/an-experimental-study-on-the-optimum-installation-of-fire-detector-for-early-stage-fire-detecting-in-rack-type-warehouses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56376.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">746</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">493</span> Identifying Model to Predict Deterioration of Water Mains Using Robust Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Go%20Bong%20Choi">Go Bong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shin%20Je%20Lee"> Shin Je Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Jin%20Yoo"> Sung Jin Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gibaek%20Lee"> Gibaek Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In South Korea, it is difficult to obtain data for statistical pipe assessment.

Selected baby vegetables have various functional materials but they have short shelf life. This study was conducted to improve storability by using suitable laser ablation OTR (oxygen transmission rate) films. Baby vegetable of endive (Cichorium endivia L.) and pak choi (Brassica rapa chinensis) for this research, around 10 cm height, cultivated in glass greenhouse during 3 weeks. Harvested endive and pak choi were stored at 8 ℃ for 5 days and were packed by PP (Polypropylene) container and covered different types of laser ablation OTR film (DaeRyung Co., Ltd.) such as 1,300 cc, 10,000 cc, 20,000 cc, 40,000 cc /m2•day•atm, and control (perforated film) with heat sealing machine (SC200-IP, Kumkang, Korea). All the samples conducted 5 times replication. Statistical analysis was carried out using a Microsoft Excel 2010 program and results were expressed as standard deviations. The fresh weight loss rate of both baby vegetables were less than 0.3 % in treated films as maximum weight loss rate. On the other hands, control in the final storage day had around 3.0 % weight loss rate and it followed decreasing quantity. Endive had less 2.0 % carbon dioxide contents as maximum contents in 20,000 cc and 40,000 cc. Oxygen contents was maintained between 17 and 20 % in endive, 19 and 20 % in pak choi. Ethylene concentration of both vegetables maintained little lower contents in 20,000 cc treatments than others at final storage day without statistical significance. In the case of hardness, 40,000 cc film was shown little higher value at both baby vegetables without statistical significance. Visual quality was good at 10,000 cc and 20,000 cc in endive and pak choi, and off-flavor was not appeard any off-flavor in both vegetables. Chlorophyll (SPAD-502, Minolta, Japan) value of endive was shown as similar result with initial in all treatments except 20,000 cc as little lower. And chlorophyll value of pak choi decreased in all treatments compared with initial value but was not shown significantly difference each other. Color of leaves (CR-400, Minolta, Japan) changed significantly in 40,000 cc at endive. In an event of pak choi, all the treatments started yellowing by increasing hunter b value, among them control increased substantially. As above the result, 10,000 cc film was most reasonable packaging film for storing at endive and 20,000 cc at pak choi with good quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title="carbon dioxide">carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf-life" title=" shelf-life"> shelf-life</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20quality" title=" visual quality"> visual quality</a>, <a href="https://publications.waset.org/abstracts/search?q=pak%20choi" title=" pak choi"> pak choi</a> </p> <a href="https://publications.waset.org/abstracts/20815/effect-of-laser-ablation-otr-films-on-the-storability-of-endive-and-pak-choi-by-baby-vegetables-in-modified-atmosphere-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20815.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">789</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">484</span> A Study on Energy Efficiency of Vertical Water Treatment System with DC Power Supply</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Kwan%20Choi">Young-Kwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gang-Wook%20Shin"> Gang-Wook Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Taek%20Hong"> Sung-Taek Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water supply system consumes large amount of power load during water treatment and transportation of purified water.

The recycling of STS produced in Korea for construction applications is limited due to its poor hydraulic properties. On the other hand, STS has high carbonation reactivity to CO2 as it contains gamma-C2S content. This material is ideal for mineral carbonation which is one of the techniques proposed for carbon emission reduction. The objective of this study is to investigate the feasibility of developing a zero-cement STS binder activated by carbonation as alternative cementitious material. The quantitative analyses for CO2 uptake of STS powder and STS blended cement were investigated using thermogravimetric analysis (TGA), X-ray diffraction (XRD). In addition, the compressive strength and microstructure of STS pastes after CO2 curing were evaluated. Test results showed that STS can be activated by carbonation to gain a sufficient strength as alternative cementitious material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gamma-C2S" title="gamma-C2S">gamma-C2S</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20uptake" title=" CO2 uptake"> CO2 uptake</a>, <a href="https://publications.waset.org/abstracts/search?q=carbonation" title=" carbonation"> carbonation</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel%20slag" title=" stainless steel slag"> stainless steel slag</a> </p> <a href="https://publications.waset.org/abstracts/75421/development-of-zero-cement-binder-activated-by-carbonation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75421.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">464</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">481</span> Paper-Based Colorimetric Sensor Utilizing Peroxidase-Mimicking Magnetic Nanoparticles Conjugated with Aptamers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min-Ah%20Woo">Min-Ah Woo</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Cheol%20Lim"> Min-Cheol Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Joo%20Chang"> Hyun-Joo Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Wook%20Choi"> Sung-Wook Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We developed a paper-based colorimetric sensor utilizing magnetic nanoparticles conjugated with aptamers (MNP-Apts) against <em>E. coli</em> O157:H7.

The efficacy of the self-help therapy was analyzed by using mixed ANOVAs. There were significant differences in the rate of occurrence of mania or depression between the two groups. ST group reported stable moods on mood chart, and reductions in mood symptoms and improvements in quality of life and treatment adherence. This study was confirmed applicable to BD to the self-help therapy for patients with BD conducted first in Korea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self%20help%20therapy" title="self help therapy">self help therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=bipolar%20disorder" title=" bipolar disorder"> bipolar disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20help" title=" self help"> self help</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20therapy" title=" self therapy"> self therapy</a> </p> <a href="https://publications.waset.org/abstracts/37802/a-study-on-the-development-of-self-help-therapy-for-bipolar-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37802.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">677</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">477</span> Two-Step Patterning of Microfluidic Structures in Paper by Laser Cutting and Wax Printing for Mass Fabrication of Biosensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bong%20Keun%20Kang">Bong Keun Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Suk%20Oh"> Sung Suk Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-Woo%20Sohn"> Jeong-Woo Sohn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ryul%20Choi"> Jong-Ryul Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Ho%20Kim"> Young Ho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we describe two-step micro-pattering by using laser cutting and wax printing. Wax printing is performed only on the bridges for hydrophobic barriers. We prepared 405nm blue-violet laser module and wax pencil module. And, this two modules combine x-y plot. The hollow microstructure formed by laser patterning define the hydrophilic flowing paths. However, bridges are essential to avoid the cutting area being the island. Through the support bridges, microfluidic solution spread out to the unnecessary areas. Chromatography blotting paper was purchased from Whatman. We used 20x20 cm and 46x57 cm of chromatography blotting paper. Axis moving speed of x-y plot was the main parameter of optimization. For aligning between the two patterning, the paper sheet was taped at the bottom. After the two-step patterning, temperature curing step was done at 110-130 °C. The resolution of the fabrication and the potential of the multiplex detection were investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C2%B5PADs" title="µPADs">µPADs</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidic" title=" microfluidic"> microfluidic</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensor" title=" biosensor"> biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=mass-fabrication" title=" mass-fabrication"> mass-fabrication</a> </p> <a href="https://publications.waset.org/abstracts/62844/two-step-patterning-of-microfluidic-structures-in-paper-by-laser-cutting-and-wax-printing-for-mass-fabrication-of-biosensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62844.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">467</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">476</span> Cyclic Loading Tests of Reinforced Concrete Frame Structures Strengthened by Externally-Anchored Precast Wall-Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Ho%20Choi">Seung-Ho Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Yuel%20Oh"> Jae Yuel Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Sung%20Lim"> Chi Sung Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Seong%20Jung"> Ho Seong Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Su%20Kim"> Kang Su Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, various strengthening methods for buildings have been developed, but most of them require quite a long construction period during which the building users need to be patient on uncomfortable working environments including various lousy noises or even evacuation of the buildings. In this study, externally anchored precast wall-panel method (EPCW) for strengthening non-seismic reinforced concrete (RC) structures has been proposed, which is occupant-friendly technique because the strengthening walls are manufactured at factory and can be tightened to the members very quickly at the site. In order to investigate the structural performance of the specimens strengthened by the EPCW method, a total of four specimens were fabricated, and tested under axial and reversed cyclic lateral loads. The test results showed that the lateral resistances of the specimens strengthened by the EPCW method were greatly enhanced in both positive and negative directions, compared to the RC specimen having non-seismic details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=precast%20wall" title="precast wall">precast wall</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20strengthening" title=" seismic strengthening"> seismic strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=externally-anchored" title=" externally-anchored"> externally-anchored</a> </p> <a href="https://publications.waset.org/abstracts/75858/cyclic-loading-tests-of-reinforced-concrete-frame-structures-strengthened-by-externally-anchored-precast-wall-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75858.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">299</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">475</span> Improvement of Performance of Anti-Splash Device for Cargo Oil Tank Vent Pipe Using CFD Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Min%20Kim">Sung-Min Kim</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=Hyuk%20Choi"> Hyuk Choi</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.

The Royal Project Foundation is, therefore, well aware of organic agriculture. The project only focused on using natural products and utilizing its highland biological merits to increase resistance to diseases and insects for the produce grown. The project also brought in basic knowledge from a variety of available research information, including, but not limited to, improvement of soil fertility and a control of plant insects with biological methods in order to lay a foundation in developing and promoting farmers to grow quality produce with a high health safety. This will finally lead to sustainability for future highland agriculture and a decrease of chemical use on the highland area which is a source of natural watershed. However, there are still shortcomings of the postharvest management in term of quality and losses, such as bruising, rottenness, wilting and yellowish leaves. These losses negatively affect the maintenance and a shelf life of organic vegetables. Therefore, it is important that a research study of the appropriate and effective postharvest management is conducted for an individual organic vegetable to minimize product loss and find root causes of postharvest losses which would contribute to future postharvest management best practices. This can be achieved through surveys and data collection from postharvest processes in order to conduct analysis for causes of postharvest losses of organic pak-choi, baby pak-choi, and choy sum. Consequently, postharvest losses reduction strategies of organic vegetables can be achieved. In this study, postharvest losses of organic pak choi, baby pak-choi, and choy sum were determined at each stage of the supply chain starting from the field after harvesting, at the Development Center packinghouse, at Chiang Mai packinghouse, at Bangkok packing house and at the Royal Project retail shop in Chiang Mai. The results showed that postharvest losses of organic pak-choi, baby pak-choi, and choy sum were 86.05, 89.05 and 59.03 percent, respectively. The main factors contributing to losses of organic vegetables were due to mechanical damage and underutilized parts and/or short of minimum quality standard. Good practices had been developed after causes of losses were identified. Appropriate postharvest handling and management, for example, temperature control, hygienic cleaning, and reducing the duration of the supply chain, postharvest losses of all organic vegetables should be able to remarkably reduced postharvest losses in the supply chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=postharvest%20losses" title="postharvest losses">postharvest losses</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20vegetables" title=" organic vegetables"> organic vegetables</a>, <a href="https://publications.waset.org/abstracts/search?q=handling%20improvement" title=" handling improvement"> handling improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title=" shelf life"> shelf life</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/92052/postharvest-losses-and-handling-improvement-of-organic-pak-choi-and-choy-sum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">477</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">472</span> Effect of Mineral Admixture on Self-Healing Performance in Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Cheol%20Choi">Young-Cheol Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Won%20Yoo"> Sung-Won Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong%20Chun%20Lee"> Bong Chun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Byoungsun%20Park"> Byoungsun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Hwa%20Jung"> Sang-Hwa Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cracks in concrete commonly provide the passages of ingresses of aggressive and harmful ions into concrete inside and thus reduce the durability of concrete members. In order to solve this problem, self-healing concrete based on mineral admixture has become a major issue. Self-healing materials are those which have the ability of autonomously repairing some damages or small cracks in concrete structures. Concrete has an inherent healing potential, called natural healing, which can take place in ordinary concrete elements but its power is limited and is not predictable. The main mechanism of self-healing in cracked concrete is the continued hydration of unreacted binder and the crystallization of calcium carbonate. Some mineral admixtures have been found to promote the self-healing of cementitious materials. The aim of this study is to investigate the effect of mineral admixture on the self-healing performances of high strength concrete. The potential capability of self-healing of cementitious materials was evaluated using isothermal conduction calorimeter. The self-healing efficiencies were studied by means of water flow tests on cracked concrete specimens. The results show a different healing behaviour depending on presence of the crystalline admixture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mineral%20admixture" title="mineral admixture">mineral admixture</a>, <a href="https://publications.waset.org/abstracts/search?q=self-healing" title=" self-healing"> self-healing</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20flow%20test" title=" water flow test"> water flow test</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/75654/effect-of-mineral-admixture-on-self-healing-performance-in-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75654.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">368</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">471</span> Design of a Simple Smart Greenhouse for Optimized Pak choi Cultivation in Rural Tropical Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dedie%20Tooy">Dedie Tooy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rio%20Kolibu"> Rio Kolibu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rio%20Putra"> Rio Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Herry%20Frits%20Pinatik"> Herry Frits Pinatik</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20P.%20M.%20Ludong"> Daniel P.

Pak choi, a high-demand leafy vegetable in Indonesia, often experiences suboptimal growth due to elevated temperatures and humidity. The objective of this research is to design and develop an intelligent greenhouse to optimize pak choi cultivation in tropical rural climates. The design of a smart greenhouse provides a controlled environment to stabilize these conditions, but managing fluctuating temperature, humidity, and light in tropical regions remains challenging. This system regulates critical environmental factors, including temperature, humidity, irrigation system, and light, creating optimal conditions for Pak Choi. The prototype's effectiveness was evaluated by monitoring growth indicators such as leaf weight, freshness, and moisture content, alongside the consistency of the internal climate compared to external conditions. Results indicate that the smart greenhouse supports superior crop growth, enhances yield quality, and reduces environmental resource consumption. The irrigation control system test was carried out for 40 days. Researchers observed the results of the automatic system working according to the sensor value readings. The results of the temperature control system test work: when the air temperature in the greenhouse is more than 33 degrees, the condensation pump will turn on, and when the temperature is below 32 degrees, the pump will automatically turn itself off. The cycle repeats continuously. The results achieved pak coy can live up to 40 days. As part of our ongoing research, we are actively considering integrating double-layered roofs to improve insulation and reduce external temperature fluctuations, which could further enhance the effectiveness of the smart greenhouse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20greenhouse" title="smart greenhouse">smart greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=horticulture" title=" horticulture"> horticulture</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20tropical%20climate" title=" rural tropical climate"> rural tropical climate</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20agriculture" title=" sustainable agriculture"> sustainable agriculture</a> </p> <a href="https://publications.waset.org/abstracts/195110/design-of-a-simple-smart-greenhouse-for-optimized-pak-choi-cultivation-in-rural-tropical-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195110.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">8</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">470</span> The Effect of Remifentanil on Emergence Agitation after Sevoflurane Anesthesia in Children: A Meta-Analysis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong%20Yeop%20Kim">Jong Yeop Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Young%20Park"> Sung Young Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Hee%20Kim"> Dae Hee Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Bum%20Joe"> Han Bum Joe</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Young%20Yoo"> Ji Young Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Bum%20Choi"> Jong Bum Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sook%20Young%20Lee"> Sook Young Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emergence agitation (EA) is commonly reported adverse events after sevoflurane anesthesia in pediatric patients. 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">469</span> Experimental Study on the Creep Characteristics of FRC Base for Composite Pavement System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Woo-Tai%20Jung">Woo-Tai Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Yong%20Choi"> Sung-Yong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Hwan%20Park"> Young-Hwan Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The composite pavement system considered in this paper is composed of a functional surface layer, a fiber reinforced asphalt middle layer and a fiber reinforced lean concrete base layer. The mix design of the fiber reinforced lean concrete corresponds to the mix composition of conventional lean concrete but reinforced by fibers. The quasi-absence of research on the durability or long-term performances (fatigue, creep, etc.) of such mix design stresses the necessity to evaluate experimentally the long-term characteristics of this layer composition. This study tests the creep characteristics as one of the long-term characteristics of the fiber reinforced lean concrete layer for composite pavement using a new creep device. The test results reveal that the lean concrete mixed with fiber reinforcement and fly ash develops smaller creep than the conventional lean concrete. The results of the application of the CEB-FIP prediction equation indicate that a modified creep prediction equation should be developed to fit with the new mix design of the layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creep" title="creep">creep</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20concrete" title=" lean concrete"> lean concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20reinforced%20concrete" title=" fiber reinforced concrete"> fiber reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=base" title=" base"> base</a> </p> <a href="https://publications.waset.org/abstracts/1482/experimental-study-on-the-creep-characteristics-of-frc-base-for-composite-pavement-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1482.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">522</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">468</span> Coupled Analysis with Fluid and Flexible Multibody Dynamics of 6-DOF Platform with Liquid Sloshing Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Pill%20Kim">Sung-Pill Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Gyu%20Sung"> Dae-Gyu Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee-Sung%20Shin"> Hee-Sung Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Chun%20Park"> Jong-Chun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When a sloshing tank filled partially with liquid is excited with the motion of platform, it can be observed that the center of mass inside the tank is changed and impact loads is instantaneously applied to the wall, which causes dynamic loads additionally to the supporting links of platform. In this case, therefore, the dynamic behavior of platform associated with fluid motion should be considered in the early stage of design for safety and economics of the system. In this paper, the dynamic loads due to liquid sloshing motion in a rectangular tank which is loaded up on the upper deck of a Stewart platform are simulated using a coupled analysis of Moving Particle Simulation (MPS) and Flexible Multi-Body Dynamics (FMBD). The co-simulation is performed using two commercial softwares, Recurdyn for solving FMBD and Particleworks for analyzing fluid motion based on MPS method. For validating the present coupled system, a rectangular sloshing tank being enforced with inline sway motion by 1-DOF motion platform is assumed, and time-varied free-surface elevation and reaction force at a fixed joint are compared with experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20loads" title="dynamic loads">dynamic loads</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20sloshing%20tank" title=" liquid sloshing tank"> liquid sloshing tank</a>, <a href="https://publications.waset.org/abstracts/search?q=Stewart%20platform" title=" Stewart platform"> Stewart platform</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20particle%20semi-implicit%20%28MPS%29%20method" title=" moving particle semi-implicit (MPS) method"> moving particle semi-implicit (MPS) method</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20multi-body%20dynamics%20%28FMBD%29" title=" flexible multi-body dynamics (FMBD)"> flexible multi-body dynamics (FMBD)</a> </p> <a href="https://publications.waset.org/abstracts/32915/coupled-analysis-with-fluid-and-flexible-multibody-dynamics-of-6-dof-platform-with-liquid-sloshing-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32915.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">706</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">467</span> A Study on Analysis of Magnetic Field in Induction Generator for Small Francis Turbine Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Kwan%20Choi">Young-Kwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Sang%20Jeong"> Han-Sang Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeon-Ho%20Ok"> Yeon-Ho Ok</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Choi"> Jae-Ho Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to verify validity of design by testing output of induction generator through finite element analysis before manufacture of induction generator designed. Characteristics in the operating domain of induction generator can be understood through analysis of magnetic field according to load (rotational speed) of induction generator. Characteristics of induction generator such as induced voltage, current, torque, magnetic flux density (magnetic flux saturation), and loss can be predicted by analysis of magnetic field. <p
