The purpose of this study is to find out some hidden factors related to the moderate drinking of female workers and grasp heir relationship to drinking rate. As for the method of this study, the questionnaire was developed through the analysis of the recorded data obtained from the profound interview with some female workers who worked for a plastic company in seoul. This tool was used to collect the data for the research in the same company from Dec. 3 to Dec. 4, 2001.. The collected data were analysed through SPSS package. The obtained results are as follows. 1. Two hidden factors proved to be involved in the moderate drinking of female workers and they were named 'intimacy' and 'drinking manners' respectively. 2. One of the two hidden factors, 'intimacy' could explain 47% of the amount of drinking of female workers. The other hidden factor, 'drinking manners' could explain 28% of their amount of drinking by itself and it could explain 58%, along with two more variables 'educational background' and 'perception of life quality'. These results are expected to be used as useful materials by health managers to guide female workers to 'moderate drinking'. However, to get more confidence, similar researches need to be conducted repeatedly by occupation and size.

The purpose of this study is to find out factors related to the health perception and locus of control of the college students majoring in physical education. The questionnaire survey was conducted on the students attending five universities in urban area between June 1 and June 30, 2000. A total of 511 questionnaires were collected and analyzed by SPSS/PC+. The obtained results are as follows. 1. The level of their health perception was over average, and their health locus-of-control was approximate to the internal tendency. 2. Pearson correlation coefficients between their health perception and locus-of-control turned out to be 304. The most influential factor on the health perception was 'internal' locus-of-control, which could explain 13.5% of their health perception. The most influential factor on their internal locus-of-control was the perception of 'regimen' which could explain 13.3% of their locus-of-control. In conclusion, it is necessary to introduce the curriculum whose contents focus on intensifying the will power to practice health promotion habits.
Development of an SIS (Superconductor-Insulator-Superconductor) Junction Mixer over 120~180 GHz Band

120∼180 GHz 대역의 고정 튜닝방식을 사용한 SIS(Superconductor-Insulator-Superconductor) 접합 믹서를 개발하였다. 이 믹서는 노베야마 전파천문대에서 제작된 6개 직렬 연결 Nb/Al-Al2O3/Nb SIS 접합 소자를 사용하였으며 석영유리 기판에 제작된 이 SIS 칩은 전 주파수 대역에서 입력신호 결합을 향상시키기 위해 half-height 도파관의 중심에 놓여 있다. 본 논문에서 개발된 SIS 믹서는 기계적인 튜닝 장치를 사용하지 않으며 RF 신호와 LO 전력은 냉각된 십자형 방향성 결합기를 통해서 믹서에 공급된다. 또한 IF 신호 손실을 줄이기 위해 SIS 믹서의 IF 출력 임피던스를 IF 증폭단의 50 Ω 입력 임피던스에 정합 시켰다. SIS 수신기의 측정된 DSB 잡음온도는 120∼180 GHz 대역에서 32∼131 K이며 본 논문에서 개발된 SIS 믹서는 대덕전파천문대의 14 m 전파망원경에 설치되어 전파천문 관측에 사용되고 있다.
다층구조와 전자장결합 급전구조를 갖는 사각형 마이크로스트립 패치안테나의 해석

In this papaer, the input impedance of the rectangular microstrip patch antennas with the multilayered structure is analysed by using the moment method technique in the spectral domain. The analysis is carried out for two different feeding structures : directfeeding structure and electromagnetic-feeding structure. In order to obtain the accurate input impedance, the current distribution on the microstrip feed line is modeled by the quasi-TEM travelling wave and the PWS(piecewise sinusoidal) mode. The input impedances of the designed microstrip antennas are measured and compared with the calculation. which shows a good agreement.
Death from 2,4-Dinitrophenol Poisoning: An Autopsy Case
정문희,이수진,유성호,김형석 대한법의학회 2020 대한법의학회지 Vol.44 No.3
DNP (2,4-dinitrophenol) has been commonly used as a weight loss aid; in particular, it has been used by body builders to achieve significant fat loss while maintaining muscle mass. The sale of DNP was banned due to some cases of fatal poisoning. We describe an autopsy case of a 39-year-old man who died from taking DNP to treat obesity. He was 183 cm tall and weighed 101 kg (body mass index of 31). External examination did not reveal any specific findings implicating the cause of death. Gross examination revealed that the heart weight was 450 g, and there were no significant findings in the coronary arteries and myocardium, except for a few petechiae of the epicardium. The DNP concentration in the subject’s blood was 38.28 mg/L. According to references, a DNP blood concentration of 28 mg/L or higher would result in death. Therefore, the cause of death in this autopsy case was DNP toxicity.
