이 연구의 목적은 여자대학생의 지각된 스트레스에 영향을 미치는 요인을 파악하기 위한 기초조사연구이다. 이 연구는 횡단적 서술적 조사로 3개 도서지역의 여자대학생 459명을 대상으로 2017년8월 27일부터 10월 26일까지 온라인 설문방법으로 자료를 수집하였다. 지각된 스트레스에 영향을미치는 요인은 단계적 다중회귀분석방법으로 분석하였다. 여자대학생의 특성에 따른 지각된 스트레스는 운동을 하지 않는 경우에, 성매개질환감염 경험이 있는 경우에 높았다. 지각된 스트레스는 자기효능감과 음의 상관관계를, 불확실성 불내성과는 양의 상관관계를 보였다. 지각된 스트레스의 평균점수는 17.45±4.79(범위:6-40이었다. 여자대학생의 지각된 스트레스에 영향을 미치는 요인은 자기효능감, 불확실성 불내성, 건강상태, 성매개질환감염이었고, 이 4가지 변수는 지각된 스트레스 회귀모델에서 37.7 %의 설명력을 나타냈다(F = 70.38, p<.001). 이 연구의 결과를 토대로 여자대학생의지각된 스트레스를 감소시키기 위해서는 성매개질환감염을 예방하고, 건강상태를 좋게 유지하도록하고, 불확실성 불내성은 감소시키고 자기효능감을 향상시키는 중재를 개발할 필요가 있다. The purpose of this study was to identify factors influencing the perceived stress among female college students. The cross-sectional survey data were collected from 459 female college students in three provinces in South Korea by online method from August 27 to October 26, 2017., and analyzed by a stepwise multiple regression method. The perceived stress level was found high among those with no regular exercise or experiences with sexually transmitted infections. It was negatively correlated with self-efficacy, but positively correlated with uncertainty intolerance. The mean score of perceived stress was 19.45±4.79 (range: 6-40). The factors influencing the perceived stress of female college students include self-efficacy, intolerance of uncertainty, health status, and experiences with sexual transmitted infections, which explained 37.7% of the variability in the perceived stress according to the regression model (F=70.38, p<.001). The findings of this study suggest a need of developing interventions that prevent sexually transmitted infections, reduce intolerance of uncertainty, maintain good health, and increase self-efficacy in order to reduce the perceived stress of female college students in South Korea.

PEMFC performance is changed by the very complicated physical phenomenon. In this study, numerical analyses on performance for Fuel Cell in the aspects of water management were performed to compare Serpentine channel flow fields of 5pass 4turn Serpentine and 25㎠ reaction surface between with and without sub channel at rib. PEMFC operating conditions were the same and the inlet flow velocity was controlled by stoichiometric numbers of 1.5 at anode and 2.0 at cathode. Through the supplement of sub channel flow field, it is shown from the results that water removal characteristic inside channel improves because the flow direction of under-rib convection is changed into the sub channel. Reacting gases supplied from entrance disperse into sub channel flow field and electrochemical reaction occurs uniformly over the reaction surface. Therefore, it was also known that total current density distributions become uniform because retention time of reacting gases traveling to sub channel flow field is longer than to main channel.

Proton exchange membrane electrolyzer has various influence factors on performance. In this paper, the analytic model is designed for proton exchange membrane electrolyzer based on electrochemical reaction and conservation of mole balance at the anode and cathode. It includes production hydrogen and oxygen, rated voltage accommodating variation in current density and temperature in active area 25㎠. Moreover, the model is considered that variation of pressure in the stored hydrogen gas generated by electrolysis. The analysis results show that proton exchange membrane electrolyzer performance increases as the current density and temperature increases. The model is designed with MATLAB and Simulink, and will be investigated experimentally in the future.

수소가 매력적인 연료로 각광받기 시작하면서 수요가 급증하였으며 이에 대응하여 수소 생산 기술에 대한 연구가 필요하다. 본 연구에서는 산소-메탄올 비율에 따른 연료전지용 메탄올 개질기의 반응 효율을 알아보았다. 각각의 촉매 배열에 따른 산소-메탄올의 비율(O₂/CH₃ OH)의 영향을 알아보기 위해 O₂/CH₃ OH를 0.1에서 0.4까지 0.05씩 증가시켜 반응기의 온도, 변환율, 효율에 관한 실험을 수행하였다. O₂/CH₃ OH가 0.15에서 0.2로 증가할 때 촉매층(catalyst bed)의 온도도 증가하며, 흡열 반응이 발열반응으로 변하여 반응기의 온도를 상승시켜 촉매 점화에 따라 온도는 235 ℃정도 급상승한 500 ℃가 된다. 반응기의 성능은 O₂/CH₃ OH에 크게 의존하며 이론적 연구에서 O₂/CH₃ OH는 0.23이었으나 실험 결과는 30 % 높은 0.30일 때 최적의 성능을 나타내었다. 이것은 혼합기체의 농도차이, 반응속도, 촉매, 반응기의 열손실, 반응 시 생성된 생성물 등의 변화 때문인 것으로 여겨진다. The use of Hydrogen as a fuel is receiving considerable attention and as a result, research on novel methods of hydrogen production is necessary so that the hydrogen demands in the future can be satisfied. This study presents experimental data on methanol Autothermal Reformation that quantifies the relationship between the oxygen-to-methanol ratio (O₂/CH₃OH) and reformer efficiency. For each catalyst configuration, the O₂/CH₃OH was varied from 0.1 to 0.4, with an increment of 0.05, to investigate the effects of O₂/CH₃OH on the reactor performance, including temperature profile, conversion, and efficiency. O₂/CH₃OH was increased from 0.15 to 0.20, and the catalyst bed temperature increased by 235 ℃ to approximately 550 ℃. The catalyst bed temperature increased with increasing O₂/CH₃OH as the reaction shifted from endothermic to exothermic reaction and as a result, excess heat, which raised the reactor temperature, was generated. The reactor performance was shown to be highly dependent on O₂/CH₃OH. The optimum O₂/CH₃OH = 0.30 found in the experimental tests is 30% higher than the theoretical optimum of 0.23. This is attributed to a combination of factors such as the concentrations of the O₂ and CH₃OH gas, reaction rate, catalyst effects, heat loss from the reactor, and the difference between the actual amounts of reaction products formed and the theoretical amounts of the reaction products.

본 연구의 목적은 한국, 중국 및 일본에 거주하는 한국계 노인들을 대상으로 건강상태를 평가하는 것으로 한국에 거주하는 노인 및 한국에서 출생 한 후 중국과 일본으로 이주한 노인을 대상으로 건강상태를 비교, 분석하였다. 본 연구의 대상자는 한국노인 231명, 일본노인 126명, 중국노인 246명으로 총 603명이었으며 평균 연령은 74.4세였다. 한국, 중국, 노인의 건강상태는 한국 노인이 중국과 일본 노인에 비해서 건강상태의 평균점수가 높았다. 노인의 건강상태에 영향을 미치는 특성 으로는 연령, 성별, 결혼상태, 종교, 교육정도, 용돈, 흡연과 음주, 수면시간 및 건강관리방법에 따라 유의한 차이가 있었다. 본 연구결과 한국, 중국, 일본의 문화적 차이에 따라 거주하는 노인의 일반적 특성, 건강상태, 일반적 특성에 따른 건강상태에 차이가 있음이 나타났다. 따라서 추후 노인의 건강증진 방안 모델 제시에는 노인들의 문화적 특성이 고려되어져야 할 것으로 판단된다. Most overseas Korean seniors live in China and Japan due to Korea’s historical background. Although Korean seniors living in Korea China and Japan share some similarities, the overseas seniors have become culturally different as they adapted to their countries of residence. Therefore, the aim of this study was to provide basic reference data for future senior health enhancement models by comparing and analyzing the health of Korean and overseas Korea seniors. The number of subjects in this study was 603 people, which was comprised of 231 Korean seniors, 246 overseas seniors in China, and 126 overseas seniors in Japan. The average age of the subjects was 74.4 years old. The Korean seniors displayed higher average health score than the overseas seniors. Therefore, the study believes that cultural elements should be considered in a future senior health enhancement model.
