Objectives: The purpose of this study was to examine affecting factors on problematic drinking of college students. Methods: The subjects were 258 college students. Data collected from November 28 through December 9, 2016. Collected data were analyzed with Independent t-test, One-way ANOVA, Pearson`s correlation and multiple regression analysis. Results: Problematic drinking based on general characteristics showed statistically significant difference in gender, age, grade, resident type, major GPA, having smoke and drinking cost. The factors affecting problematic drinking were as follows: high drinking costs, low major GPA, smoker, drinking refusal self-efficacy and drinking motivation. The explanatory power of theses factors was 54.3%. Conclusions: This findings suggest that in order to reduce the problematic drinking of college students, it is necessary to develop and apply a reducing drinking program considering individual factors, cognitive factors, and socio-cultural factors and it should be approached from a diverse and comprehensive viewpoint including smoking cessation education.

In our study, osteoporosis was induced by ovariectomized in female Sprague-Daweley rats, and the prevention and treatment efficacy of the climacteric disease the postmenopausal Type I pattern was examined by using the experimental substance soybeans and arrowroot. After ovariectomy, the amount of estrogen was found to be reduced by 21.37% and it showed the tendency to be increased by 4.49% in T1 (extraction of soybeans group) and 7.62% in T2 (extraction of ferment soybeans group). The change of bone density, 14 weeks after ovariectomy in the femur, was decreased by 9.33% in N.C. group, and 5.46% in T3 (extraction of ferment arrowroot group). As pathological findings, the trabeculae of femur were detected to be abundant as normal and the frequency of the appearance of osteoclasts was very minimal. In the T3, the frequency of the appearance of the trabeculae of femur was increased to the level that could be distinguished. In regard to the accumulation of lipid in the bone marrow, the accumulation of lipid in the bone marrow was low as normal. However, in T3, the decrease to the level that could be distinguished was detected. In addition, in regard to the pathological findings of the uterus, normal uterine tissue findings were detected. In the T3, the minimal atrophy findings were detected. In conclusion, when the T3 was orally administered continuously for 14 weeks, it was thought that a certain proportion of the hormonal balance was maintained that functioned as a substance interfering the accumulation of fat, and it was considered to be of help in the treatment of not only osteoporosis Type I, but also for the prevention and treatment of various endocrinal diseases.

KSLV-l의 탑재 시스템은 발사 전부터 발사 후 임무 종료 시까지 발사체 및 탑재위성에 대한 각종동작상태 및 특성에 관한 제반자료를 원격측정 지상국시스템으로 전송한다. 원격측정 지상국시스템의 안테나시스템은 이러한 원격측정신호를 실시간으로 획득한 후 자료처리시스템으로 공급하고, 자료처리시스템은 수신한 텔레메트리 데이터를 처리?저장한 후 임무진행자들에게 분배하여 발사 진행시 발사임무진행을 위한 판단자료로 활용하도록 한다. 본 논문에서는 KSLV-1 으로부터 텔레메트리 신호를 수신한 후 효율적이고 안정적인 데이터처리과정을 위한 최적의 자료처리시스템의 구성 및 기능을 제시하였다. The on-board telemetry system of KSLV-1 transmits telemetry signal for the launch vehicle and satellite to ground telemetry system in real time. In ground telemetry system, antenna system acquires telemetry signals and transfers these to data processing system. Data processing system processes and recordes telemetry data and distributes it to each mission operator in order to monitor it the operation goes well or not. This document describes the configurations and functions of data processing system designed for efficient and appropriate processing of telemetry data.

Objectives: Samul-tang(Siwu-tang) has been traditionally prescribed a medicine as a restorative. Methods: In this study, we investigated the acute toxicity about water-extracted Samul-tang(Siwu-tang). Twenty-five mice completed 14 days of oral Samul-tang(Siwu-tang) at the respective doses of 0(control group), 2560, 3200, 4000 and 5000mg/kg. Results: We observed survival rates, general toxicity, change of body weight, and autopsy. Conclusions: Compared with the control group, we could not find any toxic alteration in all treated groups (2560, 3200, 4000 and 5000mg/kg). $LD_{50}$ of Samul-tang(Siwu-tang) was over 5000mg/kg and it is very safe to ICR mice.
