The purpose of this analysis was to verify the relationship between Taekwondo centre service quality and behavioral intention. To achieve the goal, a total of 272 questionnaires were distributed to Taekwondo centre in Sichuan, China. Conducted frequency analysis, exploratory factor analysis, reliability verification, correlation analysis and multiple regression analysis by utilizing SPSS 24.0 ver. The results are as follows. First, programme and human resources factor of Taekwondo centre had effected on re-visit intention of behavioral intention. However physical environment of Taekwondo centre service quality had no effect on re-visit intention. Second, physical environment and programme factor of Taekwondo service quality had effected on oral intention of behavioral intention.

The purpose of this study is to analyze relationship between the e-health literacy and health behavior for health-related information on the Internet as a factor influencing University students' health behavior. The conclusions of this study are as follows. First, it was confirmed that the ability to use and evaluate e-health literacy had a significant effect on dietary behavior during health behavior, and it is judged that the acquisition and importance of health-related information online are increasing due to the influence of the COVID-19 situation. Second, among the sub-variables of e-health literacy, utilization ability showed a significant relationship with exercise behavior, but evaluation ability and resolution ability did not affect exercise behavior. As expected, health-related online activities seem to be increasing in the COVID-19 situation, and online information needs to be accepted through a critical attitude. Third, among the sub-variables of e-health literacy, literacy, evaluation ability, and resolution ability did not show any influence on sleep behavior. In a situation where the use of smart phones continues to increase to access online, excessive use of smart phones has negative consequences, and education and measures for proper Internet use are needed.

Purpose: This study was done to identify the differences nursing needs and satisfaction with medications in patients admitted to hospital. Method: The participants were 258 patients admitted for 3days or more to D hospital. The data were analyzed using frequencies, percentages, means, standard deviations, t-test and ANOVA, SPSS-WIN 11.0 was used to assist analysis. Results: The results are as follow: 1. Variables effecting nursing needs were education and economic level. All scores of nursing needs were higher in the group with less than middle school education compared to those with high school education or higher. 2. The scores for nursing needs were higher than the score for satisfaction in common item and injection domains. The scores for nursing satisfaction were higher than nursing needs in the oral medication domain, 3, The item with the highest difference between the scores for nursing needs and satisfaction was 'I want to know the side effect of the drugs'. Conclusion: Patients admitted to hospital want to know the therapeutic effect, side effect and reason for their drugs. However satisfaction with medication was not equal to needs. It is necessary to emphasize clinical pharmacology in nursing education programs.

전술유도무기용 소형 유압식 구동장치의 모델링 및 시뮬레이션
이도윤(Doyun Lee),이호성(Hosung Lee),안성용(Sungyong An),박연정(Yeonjung Park) 한국항공우주학회 2017 韓國航空宇宙學會誌 Vol.45 No.4
최근 전술유도무기 분야는 대부분 전기식 구동장치를 채용하고 있으나 주어진 공간조건과 무게 제한 아래 상대적으로 부하가 크며 작동시간이 짧고 동시에 빠른 응답성이 요구될 경우에는 무게 및 공간 조건을 맞추기 위해서 반드시 유압식 구동장치를 적용해야 할 경우가 발생한다. 본 논문에서는 소형 유압식 구동장치 시스템을 대상으로 수학적 모델링과 시뮬레이션을 수행하였다. 수학적 모델은 고압용기, 압력조절밸브, 저유기, 유압작동기로 나누어 구성하였으며 실험 결과와 비교하여 모델의 타당성을 검증하고 고찰하였다. 본 연구를 통하여 소형 유압식 구동장치 시스템 설계에 유용한 수학적 모델을 수립하였다. If an actuation system of the tactical missile is required very fast response time on conditions of short operating time and big loads on the actuator, we would prefer to adopt a small hydraulic system. In this paper, a mathematical model is proposed to analyze and simulate the small hydraulic actuation system. The mathematical model consists of a high pressure vessel model, a pressure regulator model, a hydraulic reservoir model and a actuator model. The suggested model is validated by comparison of simulation results with experimental data. The simulation results show that the mathematical model could be useful for designing a hydraulic actuation system.
