The MDPS system is a new power steering technology for vehicles and it can enhance driver’s convenience and fuel efficiency. AUTOSAR defines common standards for the implementation of embedded automotive software. Some aspects of safety and timing requirements are analyzed. Through the AUTOSAR methodology, the embedded software becomes more flexible, reusable and maintainable than ever.

Their widespread detection and accumulation in the environment raise concerns about whether these chemicals might be developmental toxicants and teratogens in the ecosystem. We evaluated and compared the toxicity of PFCs of containing various numbers of carbon atoms (C8-11 carbons) on vertebrate embryogenesis. We assessed the developmental toxicity and teratogenicity of various PFCs. The toxic effects on Xenopus embryos were evaluated using different methods. We measured teratogenic indices (TIs) and investigated the mechanisms underlying developmental toxicity and teratogenicity by measuring the expression of organ-specific biomarkers such as xPTB (liver), Nkx2.5 (heart), and Cyl18 (intestine). All PFCs that we tested were found to be developmental toxicants and teratogens. Their toxic effects were strengthened with increasing length of the fluorinated carbon chain. Furthermore, we produced evidence showing that perfluorodecanoic acid (PFDA) and perfluoroundecanoic acid (PFuDA) are more potent developmental toxicants and teratogens in an animal model compared to the other PFCs we evaluated [perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA)]. In particular, severe defects resulting from PFDA and PFuDA exposure were observed in the liver and heart, respectively, using the whole mount in situ hybridization, real-time PCR, pathologic analysis of the heart, and dissection of the liver. Our studies suggest that most PFCs are developmental toxicants and teratogens, however, compounds that have higher numbers of carbons (i.e., PFDA and PFuDA) exert more potent effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PFC" title="PFC">PFC</a>, <a href="https://publications.waset.org/abstracts/search?q=xenopus" title=" xenopus"> xenopus</a>, <a href="https://publications.waset.org/abstracts/search?q=fetax" title=" fetax"> fetax</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a> </p> <a href="https://publications.waset.org/abstracts/46966/evaluation-of-developmental-toxicity-and-teratogenicity-of-perfluoroalkyl-compounds-using-fetax" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46966.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">352</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">306</span> Analysis of Stacked SCR-Based ESD Protection Circuit with Low Trigger Voltage and Latch-Up Immunity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Geol%20Park">Jun-Geol Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Il%20Do"> Kyoung-Il Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Ju%20Kwon"> Min-Ju Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Hyun%20Park"> Kyung-Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Seo%20Koo"> Yong-Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we proposed the SCR (Silicon Controlled Rectifier)-based ESD (Electrostatic Discharge) protection circuit for latch-up immunity.

The architecture of the hardware is a high integrity system such that it incorporates a high performance 32-bit CPU and a separate Peripheral Control-Processor (PCP) together with an external watchdog CPU. Communication between the main CPU and the PCP is executed via a common area of RAM and events on either processor which are invoked by interrupts. Safety-related software is also implemented to provide a reliable, self-testing computing environment for safety critical and high integrity applications. The validity of the design approach is shown by using the Hardware-in-the-Loop Simulation (HILS) for Electric Power Steering (EPS) systems which consists of the EPS mechanism, the designed ECU, and monitoring tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20control%20unit" title="electronic control unit">electronic control unit</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20power%20steering" title=" electric power steering"> electric power steering</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20safety" title=" functional safety"> functional safety</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware-in-the-loop%20simulation" title=" hardware-in-the-loop simulation"> hardware-in-the-loop simulation</a> </p> <a href="https://publications.waset.org/abstracts/8013/on-the-design-of-electronic-control-unitsfor-the-safety-critical-vehicle-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8013.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">295</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">304</span> Next Generation Membrane for Water Desalination: Facile Fabrication of Patterned Graphene Membrane</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae-Kyung%20Choi">Jae-Kyung Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Soon-Yong%20Kwon"> Soon-Yong Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Duk%20Yun"> Hyung Duk Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Sang%20Chung"> Hyun-Sang Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Seongho%20Seo"> Seongho Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kukjin%20Bae"> Kukjin Bae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, there were several attempts to utilize a graphene layer as a water desalination membrane. In order to use a graphene layer as a water desalination membrane, fabrication of crack-free suspension of graphene on a porous membrane, having hydrophobic surface, and generation of a uniform holes on a graphene are very important. In here, we showed a simple chemical vapor deposition (CVD) method to create a patterned graphene membrane on a patterned platinum film. After CVD growth process of patterned graphene layer/patterned Pt on SiO2 substrates, the patterned graphene layer can be successfully transferred onto arbitrary substrates via thermal-assisted transfer method. In this result, the transferred patterned graphene membrane has so hydrophobic surface which will certainly impact on the naturally and speed pass way for fresh water. In addition to this, we observed that overlapping of patterned graphene membranes reported previously by our group may generate different size of holes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition%20%28CVD%29" title="chemical vapor deposition (CVD)">chemical vapor deposition (CVD)</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%20surface" title=" hydrophobic surface"> hydrophobic surface</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20desalination" title=" membrane desalination"> membrane desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20graphene" title=" porous graphene"> porous graphene</a> </p> <a href="https://publications.waset.org/abstracts/57970/next-generation-membrane-for-water-desalination-facile-fabrication-of-patterned-graphene-membrane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57970.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">471</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">303</span> A Different Approach to Optimize Fuzzy Membership Functions with Extended FIR Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Ho%20Chung">Jun-Ho Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Hyun%20Yoo"> Sung-Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Hwan%20Choi"> In-Hwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kook%20Lee"> Hyun-Kook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Moon-Kyu%20Song"> Moon-Kyu Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon-Ki%20Ahn"> Choon-Ki Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extended finite impulse response (EFIR) filter is addressed to optimize membership functions (MFs) of the fuzzy model that has strong nonlinearity.

All printing technology was used for the fabrication of the robot. Polyjet printing was used to print the front and back limbs, while ultrathin filament was used to print the body of the robot, which makes it a complete soft swimming robot. The dual thrust generation approach has been proposed by embedding the main muscle and antagonistic muscle in all the limbs, which enables it to attain high speed (18 mm/s), and significant control of swimming in dual modes (synchronous and asynchronous modes). To achieve the swimming motion of the frog, the design, motivated by the rigorous modelling and real frog dynamics analysis, enabled the as-developed frog robot (FROBOT) to swim at a significant level of consistency with the real frog. The FROBOT (weighing 65 g) can swim at different controllable frequencies (0.5–2Hz) and can turn in any direction by following custom-made LabVIEW software’s commands which enables it to swim at speed up to 18 mm/s on the surface of deep water (100 cm) with excellent weight balance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20robotics" title="soft robotics">soft robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20actuator" title=" soft actuator"> soft actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=frog%20robot" title=" frog robot"> frog robot</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title=" 3D printing"> 3D printing</a> </p> <a href="https://publications.waset.org/abstracts/151715/design-modelling-and-fabrication-of-bioinspired-frog-robot-for-synchronous-and-asynchronous-swimming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151715.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">301</span> A Study on the Comparatison of Mechanical and Thermal Properties According to Laminated Orientation of CFRP through Bending Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin">Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee"> Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In rapid industrial development has increased the demand for high-strength and lightweight materials. Thus, various CFRP (Carbon Fiber Reinforced Plastics) with composite materials are being used. The design variables of CFRP are its lamination direction, order, and thickness. Thus, the hardness and strength of CFRP depend much on their design variables. In this paper, the lamination direction of CFRP was used to produce a symmetrical ply [0°/0°, -15°/+15°, -30°/+30°, -45°/+45°, -60°/+60°, -75°/+75°, and 90°/90°] and an asymmetrical ply [0°/15°, 0°/30°, 0°/45°, 0°/60° 0°/75°, and 0°/90°]. The bending flexure stress of the CFRP specimen was evaluated through a bending test. Its thermal property was measured using an infrared camera. The symmetrical specimen and the asymmetrical specimen were analyzed. The results showed that the asymmetrical specimen increased the bending loads according to the increase in the orientation angle; and from 0°, the symmetrical specimen showed a tendency opposite the asymmetrical tendency because the tensile force of fiber differs at the vertical direction of its load. Also, the infrared camera showed that the thermal property had a trend similar to that of the mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carbon%20Fiber%20Reinforced%20Plastic%20%28CFRP%29" title="Carbon Fiber Reinforced Plastic (CFRP)">Carbon Fiber Reinforced Plastic (CFRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title=" bending test"> bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20camera" title=" infrared camera"> infrared camera</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a> </p> <a href="https://publications.waset.org/abstracts/21385/a-study-on-the-comparatison-of-mechanical-and-thermal-properties-according-to-laminated-orientation-of-cfrp-through-bending-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21385.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">398</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">300</span> Effects of Extract from Lactuca sativa on Sleep in Pentobarbital-Induced Sleep and Caffeine-Induced Sleep Disturbance in Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hae%20Dun%20Kim">Hae Dun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Joo%20Hyun%20Jang"> Joo Hyun Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Geu%20Rim%20Seo"> Geu Rim Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung%20Soo%20Ra"> Kyung Soo Ra</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Joo%20Suh"> Hyung Joo Suh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lactuca sativa (lettuce) has been known for its medical property to relieve anxiety and nervous. This study was implemented to investigate sleep-promoting effects of the lettuce alcohol extract (LAE). Caffeine is widely used psychoactive substance known to induced wakefulness and insomnia to its consumers. In the present study, the sedative-hypnotic activity of the LAE was studied using the method of pentobarbital-induced sleep in the mouse model. The LAE was administrated to mice 30 min before the pentobarbital injection. The LAE prolonged the pentobarbital-induced sleep duration and decreased sleep latency. The effects of LAE were comparable to those of induced by diazepam. Another study was performed to examine whether LAE ameliorates caffeine-induced sleep disturbance in mice. Additionally, caffeine (10 mg/kg, p.o) delayed sleep onset and reduced sleep duration of mice. Conversely, LAE treatment (80 or 160 mg/kg, p.o), especially at 160 mg/kg, normalized the sleep disturbance induced by caffeine. LAE supplementation can counter the sleep disturbance induced by caffeine. These results suggest that LAE possess significant sedative-hypnotic activity, which supports the popular use of lettuce for treatment of insomnia and provide the basis for new drug discovery. Furthermore, these results demonstrate that the lettuce extract may be preferable for the treatment of insomnia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caffeine" title="caffeine">caffeine</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactuca%20sativa" title=" Lactuca sativa"> Lactuca sativa</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20duration" title=" sleep duration"> sleep duration</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20latency" title=" sleep latency"> sleep latency</a> </p> <a href="https://publications.waset.org/abstracts/49766/effects-of-extract-from-lactuca-sativa-on-sleep-in-pentobarbital-induced-sleep-and-caffeine-induced-sleep-disturbance-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49766.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">308</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">299</span> Analysis of Silicon Controlled Rectifier-Based Electrostatic Discharge Protection Circuits with Electrical Characteristics for the 5V Power Clamp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Geol%20Park">Jun-Geol Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Il%20Do"> Kyoung-Il Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Ju%20Kwon"> Min-Ju Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Hyun%20Park"> Kyung-Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Seo%20Koo"> Yong-Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzed the SCR (Silicon Controlled Rectifier)-based ESD (Electrostatic Discharge) protection circuits with the turn-on time characteristics. The structures are the LVTSCR (Low Voltage Triggered SCR), the ZTSCR (Zener Triggered SCR) and the PTSCR (P-Substrate Triggered SCR). The three structures are for the 5V power clamp. In general, the structures with the low trigger voltage structure can have the fast turn-on characteristics than other structures. All the ESD protection circuits have the low trigger voltage by using the N+ bridge region of LVTSCR, by using the zener diode structure of ZTSCR, by increasing the trigger current of PTSCR. The simulation for the comparison with the turn-on time was conducted by the Synopsys TCAD simulator. As the simulation results, the LVTSCR has the turn-on time of 2.8 ns, ZTSCR of 2.1 ns and the PTSCR of 2.4 ns. The HBM simulation results, however, show that the PTSCR is the more robust structure of 430K in HBM 8kV standard than 450K of LVTSCR and 495K of ZTSCR. Therefore the PTSCR is the most effective ESD protection circuit for the 5V power clamp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESD" title="ESD">ESD</a>, <a href="https://publications.waset.org/abstracts/search?q=SCR" title=" SCR"> SCR</a>, <a href="https://publications.waset.org/abstracts/search?q=turn-on%20time" title=" turn-on time"> turn-on time</a>, <a href="https://publications.waset.org/abstracts/search?q=trigger%20voltage" title=" trigger voltage"> trigger voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20clamp" title=" power clamp"> power clamp</a> </p> <a href="https://publications.waset.org/abstracts/65650/analysis-of-silicon-controlled-rectifier-based-electrostatic-discharge-protection-circuits-with-electrical-characteristics-for-the-5v-power-clamp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65650.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">348</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">298</span> Maximum-likelihood Inference of Multi-Finger Movements Using Neural Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyung-Jin%20You">Kyung-Jin You</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiwon%20Rhee"> Kiwon Rhee</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20H.%20Schieber"> Marc H.

We present an evidence of correlation between single and multi-finger movements and also attempt a challenging task of semi-blind decoding of neural data with minimum training of the neural decoder. Data were collected from 115 task-related neurons in M1 of a trained rhesus monkey performing flexion and extension of each finger and the wrist (12 single and 6 two-finger-movements). By exploiting correlation of temporal firing pattern between movements, we found that correlation coefficient for physically related movements pairs is greater than others; neurons tuned to single finger movements increased their firing rate when multi-finger commands were instructed. According to this knowledge, neural semi-blind decoding is done by choosing the greatest and the second greatest likelihood for canonical candidates. We achieved a decoding accuracy about 60% for multiple finger movement without corresponding training data set. this results suggest that only with the neural activities on single finger movements can be exploited to control dexterous multi-fingered neuroprosthetics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finger%20movement" title="finger movement">finger movement</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20activity" title=" neural activity"> neural activity</a>, <a href="https://publications.waset.org/abstracts/search?q=blind%20decoding" title=" blind decoding"> blind decoding</a>, <a href="https://publications.waset.org/abstracts/search?q=M1" title=" M1"> M1</a> </p> <a href="https://publications.waset.org/abstracts/1874/maximum-likelihood-inference-of-multi-finger-movements-using-neural-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1874.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">320</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">297</span> Electromagnetic Interference Shielding Characteristics for Stainless Wire Mesh and Number of Plies of Carbon Fiber Reinforced Plastic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee">Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin"> Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Woo%20Hong"> Seong Woo Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Jae%20Yu"> Min Jae Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated.

It has been considered to improve immune system and physical strength. The goal of this study was to investigate the immunomodulatory effect of deer antler velvet using in vitro system. In the first step, the effects of VA (70% ethanol extract) on the proliferation of splenocytes, bone marrow cell, and macrophages were determined. Next, the effect of VA on the production of nitric oxide and phagocytic activity in macrophage were measured. The results showed that VA treatment increased concanavalin-A stimulated splenocyte, bone marrow cells, and macrophage proliferation in a dose dependent manner. VA at 50 and 100 ug/mL concentrations significantly enhanced the concanavalin-A stimulated splenocyte proliferation by 8.8% and 18.5%, respectively. The proliferation of bone marrow cells, isolated from 5wk-old ICR mice, were increased by 25.2% and 46.5% by 50 and 100 ug/mL VA treatment. RAW 264.7 cell proliferation reached peak value at 50 ug/mL of VA treatment exhibiting 108% of the basal value. Nitric oxide production by RAW 264.7 macrophage cells was slightly reduced by VA treatment but was not statistically significant. Moreover, the phagocytic activity of macrophages was enhanced by VA treatment. These results indicate that VA is effective in immune system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deer%20antler" title="deer antler">deer antler</a>, <a href="https://publications.waset.org/abstracts/search?q=splenocyte" title=" splenocyte"> splenocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20marrow%20cells" title=" bone marrow cells"> bone marrow cells</a>, <a href="https://publications.waset.org/abstracts/search?q=macrophage%20proliferation" title=" macrophage proliferation"> macrophage proliferation</a>, <a href="https://publications.waset.org/abstracts/search?q=phagocytosis" title=" phagocytosis"> phagocytosis</a> </p> <a href="https://publications.waset.org/abstracts/51025/immunomodulatory-effect-of-deer-antler-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51025.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">272</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">295</span> A Study on the Interlaminar Shear Strength of Carbon Fiber Reinforced Plastics Depending on the Lamination Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee">Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin"> Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Ho%20Ko"> Sun Ho Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The prepreg process among the CFRP (Carbon Fiber Reinforced Plastic) forming methods is the short term of ‘Pre-impregnation’, which is widely used for aerospace composites that require a high quality property such as a fiber-reinforced woven fabric, in which an epoxy hardening resin is impregnated. the reality is, however, that this process requires continuous researches and developments for its commercialization because the delamination characteristically develops between the layers when a great weight is loaded from outside. to supplement such demerit, three lamination methods among the prepreg lamination methods of CFRP were designed to minimize the delamination between the layers due to external impacts. Further, the newly designed methods and the existing lamination methods were analyzed through a mechanical characteristic test, Interlaminar Shear Strength test. The Interlaminar Shear Strength test result confirmed that the newly proposed three lamination methods, i.e. the Roll, Half and Zigzag laminations, presented more excellent strengths compared to the conventional Ply lamination. The interlaminar shear strength in the roll method with relatively dense fiber distribution was approximately 1.75% higher than that in the existing ply lamination method, and in the half method, it was approximately 0.78% higher. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber%20reinforced%20plastic%28CFRP%29" title="carbon fiber reinforced plastic(CFRP)">carbon fiber reinforced plastic(CFRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-impregnation" title=" pre-impregnation"> pre-impregnation</a>, <a href="https://publications.waset.org/abstracts/search?q=laminating%20method" title=" laminating method"> laminating method</a>, <a href="https://publications.waset.org/abstracts/search?q=interlaminar%20shear%20strength%20%28ILSS%29" title=" interlaminar shear strength (ILSS)"> interlaminar shear strength (ILSS)</a> </p> <a href="https://publications.waset.org/abstracts/21484/a-study-on-the-interlaminar-shear-strength-of-carbon-fiber-reinforced-plastics-depending-on-the-lamination-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21484.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">294</span> Adaptive Cooperative Scheme Considering the User Location</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bit-Na%20Kwon">Bit-Na Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jee%20Yang"> Hyun-Jee Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Hyun%20Ha"> Dong-Hyun Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, an adaptive cooperative scheme in the cell edge is proposed.

However, the performance of communication is not sufficiently improved since the distance between each base station and a user is still distant.

The mechanism underlying this teratogenicity was also investigated by measuring the expression of tissue-specific biomarkers such as phosphotyrosine‑binding protein, xPTB (liver); NKX2.5 (heart); and Cyl18 (intestine). Whole‑mount in situ hybridization, reverse transcriptase‑polymerase chain reaction (RT-PCR), and histologic analyses detected severe defects in the liver and heart following exposure to PFHxA or PFHpA. In addition, immunoblotting revealed that PFHpA significantly increased the phosphorylation of extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK), while PFHxA slightly increased these, as compared with the control. These results suggest that PFHxA and PFHpA are developmental toxicants and teratogens, with PFHpA producing more severe effects on liver and heart development through the induction of ERK and JNK phosphorylation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PFCs" title="PFCs">PFCs</a>, <a href="https://publications.waset.org/abstracts/search?q=ERK" title=" ERK"> ERK</a>, <a href="https://publications.waset.org/abstracts/search?q=JNK" title=" JNK"> JNK</a>, <a href="https://publications.waset.org/abstracts/search?q=xenopus" title=" xenopus"> xenopus</a> </p> <a href="https://publications.waset.org/abstracts/46964/perfluoroheptanoic-acid-affects-xenopus-embryo-embryogenesis-by-inducing-the-phosphorylation-of-erk-and-jnk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46964.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">296</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">292</span> Bone Strengthening Effects of Deer Antler Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hye%20Kyung%20Kim">Hye Kyung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung-Gyou%20Kim"> Myung-Gyou Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang-Hyun%20Leem"> Kang-Hyun Leem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been reported that deer antler extract has bone-strengthening activity and effectively used in bone diseases therapy. However, little is known about the cellular and molecular mechanism of this effect. The upper section, mid section, and base of the antler has been known to exhibit different biological properties. Present study investigated the effects of these three parts of deer antler extracts on bone formation and resorption. The effects of deer antler extracts (DH) on bone formation were determined by cell proliferation, alkaline phosphatase (ALP) activity, collagen synthesis, and mineralization in human osteoblastic MG-63 cells. The effect on bone resorption was determined by osteoclastogenesis from bone marrow-derived precursor cells driven by RANKL. Ethanol extracts of DH (50 ~ 100 µg/ml) dose-dependently increased cell proliferation, and upper part increased the cell proliferation by 118.4% while mid and base parts increased proliferation by 107.8% and 102.3%, respectively. ALP activity was significantly increased by upper part of the DH treatment. After enhancement of ALP activity, significant augmentation of collagen synthesis and calcification assessed by Sirus red and Alzarin red staining, respectively, was observed in upper part of the DH treatment. The effect of DH on bone resorption was not observed in all three parts of the DH. These results could provide a mechanistic explanation for the bone-strengthening effects of DH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20phosphatase" title="alkaline phosphatase">alkaline phosphatase</a>, <a href="https://publications.waset.org/abstracts/search?q=collagen%20synthesis" title=" collagen synthesis"> collagen synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=deer%20antler" title=" deer antler"> deer antler</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblastic%20MG-63%20cells" title=" osteoblastic MG-63 cells"> osteoblastic MG-63 cells</a> </p> <a href="https://publications.waset.org/abstracts/24280/bone-strengthening-effects-of-deer-antler-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24280.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">314</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">291</span> Anti-Osteoporotic Effect of Deer Antler in Ovariectomized Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hye%20Kyung%20Kim">Hye Kyung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung-Gyou%20Kim"> Myung-Gyou Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang-Hyun%20Leem"> Kang-Hyun Leem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The deer velvet antler is well known for its traditional medicinal value and is widely used in the clinic. It has been considered to possess bone-strengthening activity. The goal of this study was to investigate the anti-osteoporotic effect of deer antler velvet on ovariectomized rats (OVX), and their possible mechanism of the action. In the first step, the in vitro effects of DAE on bone loss were determined. The proliferation, collagen content and alkaline phosphatase (ALP) activity of human osteoblastic MG-63 cells and osteoclastogenesis from bone marrow-derived precursor cells were measured. The in vivo experiment confirmed the positive effect of DAE on bone tissue. 3-month old female Sparague-Dawley rats were either sham operated or OVX, and administered DAE (20 and 100 mg/kg) for 4 weeks. DAE increased MG-63 cell proliferation and ALP activity in a dose-dependent manner. Collagen content was also increased by DAE treatment. However, the effect of DAE on bone resorption was not observed. OVX rats supplemented with DAE showed osteoprotective effects as the bone ALP level was increased and c-terminal telopeptide level was decreased by 100 mg/kg DAE treatment compared with OVX controls. Moreover, the tartrate-resistant acid phosphatase-5b level was also decreased by DAE treatment. The present study suggests that DAE is effective in preventing bone loss in OVX rats, and may be potential therapeutic agents for the treatment of postmenopausal osteoporosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20ALP" title="bone ALP">bone ALP</a>, <a href="https://publications.waset.org/abstracts/search?q=c-terminal%20telopeptide" title=" c-terminal telopeptide"> c-terminal telopeptide</a>, <a href="https://publications.waset.org/abstracts/search?q=deer%20antler" title=" deer antler"> deer antler</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis"> osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ovariectomy" title=" ovariectomy"> ovariectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=tartrate-resistant%20acid%20phosphatase-5b" title=" tartrate-resistant acid phosphatase-5b"> tartrate-resistant acid phosphatase-5b</a> </p> <a href="https://publications.waset.org/abstracts/48669/anti-osteoporotic-effect-of-deer-antler-in-ovariectomized-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48669.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">245</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">290</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.

However, very little information is currently available for their mechanism. The prikly pear variety Opuntia ficus-indica var. Saboten (OFS) is widely cultivated in Cheju Island, southwestern region of Korea, and used as a functional food. Present study investigated the effects of OFS on pancreatic β-cell function using pancreatic islet β cells (HIT cell). Alpha-glucosidase inhibition, glucose uptake, insulin secretion, insulin sensitivity, and pancreatic β cell proliferation were determined. The inhibitory effect of ethanol extract of OFS stem on α-glucosidase enzyme was measured in a cell free system. Glucose uptake was determined using fluorescent glucose analogue, 2-NBDG. Insulin secretion was measured by ELISA assay. Cell proliferation was measured by MTT assay. Ethanol extracts of OFS dose-dependently inhibited α-glucosidase activity as well as glucose uptake. Insulinotrophic effect of OFS extract was observed at high glucose media in pancreatic β-islet cells. Furthermore, pancreatic β cell regeneration was also observed.These results suggest that OFS mediates the antidiabetic activity mainly via α-glucosidase inhibition, glucose uptake, and improved insulin sensitivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prickly%20pear%20cactus" title="prickly pear cactus">prickly pear cactus</a>, <a href="https://publications.waset.org/abstracts/search?q=Opuntia%20ficus-indica%20var.%20Saboten" title=" Opuntia ficus-indica var.

Egg yolk is composed of various important chemical substances for human health. Growth means not only the increase of body weight but also the elongation of height and the enlargement of each organ's anatomical and morphological size. A calcium shortage causes the growth retardation on the body growth. In this study, we examined the therapeutic effects of egg yolk peptide (EYP) on the retardation of the longitudinal bone growth induced by low-calcium diet (0.05%) in adolescent rats. Low calcium diets were administrated for 15 days. During the last five days, calcium and/or vitamin D and/or EYP were administrated. The body weights, longitudinal bone growth rates, the heights of growth plates, and bone morphogenetic protein (BMP)-2 and insulin-like growth factor (IGF)-1 expressions were measured using histochemical analysis. Low calcium diets caused the significant reduction in body weight gains and the longitudinal bone growth. The heights of growth plates and the expressions of BMP-2 and IGF-1 showed the impairment of body growth as well. Calcium and/or vitamin D administration could not significantly increase the longitudinal bone growth. However, calcium, vitamin D, and EYP administration significantly increased the bone growth, the growth plate height, and BMP-2 and IGF-1 expressions. These results suggest that EYP enhances the longitudinal bone growth in the calcium and/or vitamin D deficiency and it could be a promising agent for the treatment of children suffering from malnutrition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=egg%20yolk%20peptide" title="egg yolk peptide">egg yolk peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=low-calcium%20diet" title=" low-calcium diet"> low-calcium diet</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20bone%20growth" title=" longitudinal bone growth"> longitudinal bone growth</a>, <a href="https://publications.waset.org/abstracts/search?q=morphogenetic%20protein-2" title=" morphogenetic protein-2"> morphogenetic protein-2</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin-like%20growth%20factor-1" title=" insulin-like growth factor-1"> insulin-like growth factor-1</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D" title=" vitamin D"> vitamin D</a> </p> <a href="https://publications.waset.org/abstracts/11287/effects-of-egg-yolk-peptide-on-the-retardation-of-bone-growth-induced-by-low-calcium-diets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11287.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">449</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">287</span> Approach to Functional Safety-Compliant Design of Electric Power Steering Systems for Commercial Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Chul%20Koag">Hyun Chul Koag</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Sik%20Ahn"> Hyun-Sik Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose a design approach for the safety mechanism of an actuator used in a commercial vehicle’s EPS system. As the number of electric/electronic system in a vehicle increases, the importance of the functional safety has been receiving much attention. EPS(Electric Power Steering) systems for commercial vehicles require large power than passenger vehicles, and hence, dual motor can be applied to get more torque. We show how to formulate the development process for the design of hardware and software of an EPS system using dual motors. A lot of safety mechanisms for the processor, sensors, and memory have been suggested, however, those for actuators have not been fully researched.

Moreover, myristic acid significantly suppressed expression of inflammatory mediators and down-regulating UVB-induced intracellular ROS generation. Furthermore, myristic acid reduced the expression of NF-κB by inhibiting degradation of IκB-α and ERK, JNK, and p38 pathways by inhibiting phosphorylation in RAW 264.7 macrophage cells.

However, the HEAVENS model only presents a simple process, and there are no detailed procedures and activities for each process, making it difficult to apply it to the actual vehicle security vulnerability check. In this paper, we propose an automated attack database that systematically summarizes attack vectors, attack types, and vulnerable vehicle models to prepare for various car hacking attacks, and data flow diagrams that can detect various vulnerabilities and suggest a way to materialize the HEAVENS model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20security" title="automotive security">automotive security</a>, <a href="https://publications.waset.org/abstracts/search?q=HEAVENS" title=" HEAVENS"> HEAVENS</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20hacking" title=" car hacking"> car hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20model" title=" security model"> security model</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a> </p> <a href="https://publications.waset.org/abstracts/84442/a-study-on-automotive-attack-database-and-data-flow-diagram-for-concretization-of-heavens-a-car-security-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84442.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">283</span> Opuntia ficus-indica var.

The prickly pear variety Opuntia ficus-indica var. Saboten (OFS) is widely cultivated in Cheju Island, the southwestern region of Korea, and used as a functional food. The present study investigated the effects of OFS on adipogenesis, lipolysis, glucose uptake, and glucose transporter (GLUT4) expression using preadipocyte 3T3-L1 cells. Adipogenesis was determined by preadipocyte differentiation and triglyceride accumulation assessed by Oil Red O staining. Lipolysis was determined as the rate of glycerol release. Insulin-stimulated glucose uptake and GLUT4 expression were measured using fluorescent glucose analogue, 2-NBDG, and ELISA, respectively. Quantitative real-time RT-PCR was performed to investigate the effects of OFS on the mRNA expression of peroxisome proliferator-activated receptor γ (PPARγ), a regulator of adipocyte differentiation. Ethanol extracts of OFS dose-dependently enhanced adipocyte differentiation and cellular triglyceride levels indicating the enhancement of the differentiation of preadipocytes into adipocytes. Insulin-stimulated glucose uptake and GLUT4 expression were also dose-dependently increased by OFS treatment. Furthermore, OFS treatment also increased the mRNA levels of PPARγ. These effects of OFS on adipocytes suggest that OFS is potentially beneficial for type 2 diabetes by due to its enhanced glucose uptake and balanced adipogenesis and lipolysis properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3T3-L1%20preadipocyte%20cell" title="3T3-L1 preadipocyte cell">3T3-L1 preadipocyte cell</a>, <a href="https://publications.waset.org/abstracts/search?q=adipogenesis" title=" adipogenesis"> adipogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=GLUT4" title=" GLUT4"> GLUT4</a>, <a href="https://publications.waset.org/abstracts/search?q=lipolysis" title=" lipolysis"> lipolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Opuntia%20ficus-indica%20var.%20Saboten" title=" Opuntia ficus-indica var.

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">281</span> Egg Yolk Peptide Stimulated Osteogenic Gene Expression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hye%20Kyung%20Kim">Hye Kyung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung-Gyou%20Kim"> Myung-Gyou Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang-Hyun%20Leem"> Kang-Hyun Leem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Postmenopausal osteoporosis is characterized by low bone density which leads to increased bone fragility and greater susceptibility to fracture. Current treatments for osteoporosis are dominated by drugs that inhibit bone resorption although they also suppress bone formation that may contribute to pathogenesis of osteonecrosis. To restore the extensive bone loss, there is a great need for anabolic treatments that induce osteoblasts to build new bone. Pre-osteoblastic cells produce proteins of the extra-cellular matrix, including type I collagen at first, and then to successively produce alkaline phosphatase (ALP) and osteocalcin during differentiation to osteoblasts. Finally, osteoblasts deposit calcium. Present study investigated the effects of egg yolk peptide (EYP) on osteogenic activities and bone matrix gene expressions in human osteoblastic MG-63 cells. The effects of EYP on cell proliferation, alkaline phosphatase (ALP) activity, collagen synthesis, and mineralization were measured. The expression of osteogenic genes including COL1A1 (collagen, type I, alpha 1), ALP, BGLAP (osteocalcin), and SPP1 (secreted phosphoprotein 1, osteopontin) were measured by quantitative realtime PCR. EYP dose-dependently increased MG-63 cell proliferation, ALP activity, collagen synthesis, and calcium deposition. Furthermore, COL1A1, ALP, and SPP1 gene expressions were increased by EYP treatment. Present study suggested that EYP treatment enhanced osteogenic activities and increased bone matrix osteogenicgenes. These results could provide a mechanistic explanation for the bone-strengthening effects of EYP. <p class="card-text"><strong>Keywords:</strong> <a
