Sagunja-tang(Sijunzi-tang) has been traditionally prescribed as a restorative. The present study was undertaken to determine the possible toxic effects of Sagunja-tang on SD rats. In this study, we investigated the subacute toxicity of water-extracted Sagunja-tang(Sijunzi-tang) on SD rats. Twenty rats were orally adiministered Sagunja-tang for 28 days at a dose of 0 ㎎/㎏(control group) or 1500㎎/㎏(treated group), respectively. All of subjects was survived. No significant difference in abnormal clinical signs, related to hematological values, serum biochemical values, water and feed intake, coagulation time, autopsy analysis, organ weight, tissue microscopically, funduscopy, urine intake and urinalysis, was detected. Compared with the control group, we could not find any subacute toxic alteration in treated group (l500㎎/㎏) for 28 days. This result suggests that Sagunja-tang(Sijunzi-tang), a herbal medicine prescription, is a safe prescription to body.

SsangHwaTang has been traditionally prescribed a medicine as a restorative. In this study, We investigated the acute toxicity about water-extracted SsangHwaTang Twenty-five mice completed 14 days of oral SsangHwaTang at the respective doses of 0(control group), 2560, 3200, 4000 and 5000㎎/㎏. And then we observed survival rates, general toxicity, change of body weight, and autopsy. Compared with the control group, we could not find any toxic alteration in all treated groups (2560, 3200, 4000 and 5000㎎/㎏). In conclusion, LD50 of SsangHwaTang was over 5000㎎/㎏ and it is very safe to ICR mice.

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.

Purpose: This study examined the impact of a drinking reduction program on drinking motivation, drinking refusal self-efficacy, and problematic drinking behaviors in college students with problematic drinking habits. Methods: This study incorporated a non-equivalent control group prepost-test design. Study participants included 58 college students who scored 12 or more in the AUDIT-K test (Alcohol Use Disorders Identification Test-Korean version) (experimental group: 30; control group: 28). The intervention consisted of eight sessions and was conducted once a week. It was designed to promote autonomy, competence, and relatedness-the three elements of basic psychological needs in self-determination theory. The participants were assessed before the intervention, immediately after, and four weeks post intervention. Data were collected from October 12 to December 31, 2017. The analysis employed the chi-square test, Fisher’s exact test, independent t-test, and repeated measures ANOVA using SPSS/WIN 22.0. Results: The mean age of participants was 21.8 years. There were 30 men (51.7%) and 28 women (48.3%). The differences in drinking motivation, drinking refusal self-efficacy, and problematic drinking behaviors were statistically significant for the group by time interaction (F = 42.56, p < .001; F = 54.96, p < .001; F = 39.90, p < .001, respectively). Conclusion: The findings indicate that the intervention effectively decreases drinking motivation, increases drinking refusal self-efficacy, and decreases problematic drinking behaviors. It can be an efficient strategy for college students with problematic drinking habits to enhance their self-determination ability.
