The objective of epidemiology research is to analyze the relationship between outbreaks of disease and exposure to the specific risk factor. In this study, the assumption of the relationship between cause and effect and the definition of the confounding variable in the control group are designated. The study also implies the importance of assessing preliminary information at the initial step of research design.

Water to provide for human use will be critical problem we face for next century and should be major branch of an earth science. It has been anticipated that consumption of water in Korea will have outstripped available resources before 2006. Already water shortage was reported in a tributary of the Nakdong river. Water supplies from downstream area of this river such as Pusan and Kyung-Nam, we heard, have become severely contaminated by human and industrial waste products. To solve these problem and make preparations for a waterway, we propose 58 dams located upstreams, whose storage of water amount to 1.4 billion tons. By these dams, fresh water can be obtained with small submerged area compared to the dams planned by government.

Recently, there has been widespread recognition that traffic noise is a serious social problem. Soonchunhyang university also likely to be suffered by the problem because a busy highway is near the school. In this study, we examined the exposure level to traffic noise in a classroom of Soonchunhyang university. The results were as follows: 1. Total mean exposure level in classrooms was 42.6 dB. The exposure level in college of humanities was higher than that of orther colleges (college of natural sciences and college of medicine) 2. The exposure level in a classroom was 37.5 dB if the windows were kept close, and 42.5 dB if open. The level also influenced by the distance between the classroom and road. 3. After the construction of an antinoise wall, the exposure level was slightly changed from 43.3 dB to 42.3 dB. This suggest that the exposure levels were not affected by the antinoise wall.

An attempt was made to determine the factors influencing personal exposure levels of NO₂ for housewives living in urban area in Korea and Japan. NO₂was measured with small passive sampler containing Triethanolamine, and samplers were set for 24 hours at volunteers (personal exposure level), near the TV in living room (indoor level) and near the porch of their houses (outdoor level). The subjects recorded the time of spending cooking using gas appliances, using kitchen ventilator and unvented oil or gas heater, total of minutes of opening window, going out of home and room. There was an apparent increase in personal exposure level in the case of the unvented heater and also and increased by cooking on a gas range in Korea and Japan. Through these observations, we concluded that personal exposure level of NO₂ was strongly related to indoor NO₂level, and the factors influencing indoor NO₂level seemed different between in Korea and Japan. The biggest factor in the former was indoor pollution and in the latter, was the level of outdoor environment.

GeS 결정은 승화법에 의해 성장시키고 GeSe 결정은 vapour transport 방법을 이용하여 성장시켰다. GeS와 GeSe 결정은 orthorhombic 구조를 가지고 있다. 297K에서 optical energy gap은 1.64eV(GeS), 1.51eV(GeSe)이고, GeS의 광전도도는 764nm에서 peak가 나타난다. GeSe의 전기적 특성을 알아보기 위하여 van der Pauw 방법을 사용하여 Hall 효과를 측정했다. Crystals of GeS were obtained by sublimation of GeS chunks between 520℃ and 580℃ in closed evacuated (10?? torr) quartz ampoule using a vertical pulling method, and GeSe crystals were grown in an ampoule by vapour transport method. Both GeS and GeSe crystals had the orthorhombic structures and the lattice constants were measured to be ??, ?? and ?? (GeS); ??, ??, ?? (GeSe), respectively. At the temperature of 297K the optical energy gaps were 1.64eV (GeS), 1.51eV (GeSe), respectively. The photocurrent spectra of GeS measured at room temperature show a peak at 764nm. In order to investigate the temperature dependence of the electrical characteristies of GeSe crystals, the Hall effect was measured by using van der Pauw method.

The prevalence of chronic respiratory symptoms was determined in 805 Residents 30 to 49 year of age in areas along major traffic arterials, in Tokyo Metropolis. Each resident was divided into three groups with respect to distances from the major arterials to household location. Some of chronic respiratory symptoms, that is, chronic cough, chronic phlegm, chronic wheeze, breathlessness, were reported more frequently among residents nearer to the road, these results suggest that exposure to automobile exhaust is significant risk in development of chronic respiratory symptoms.

For the investigation of the relationship between the exposure and the disease, it is necessary to infer the degree of the relationship. Some biologically deducible epidemiology parameters are useful for this. These parameters are the difference between risks, the rate ratio, the rate difference, and the assumption rate ratio by Odd's ratio. The investigation of the degree of inferential epidemiology parameters is important. and it is manifested by the confidential interval.

The indoor and outdoor levels of nitrogen dioxide (NO2) and sulfur dioxide (SO2) were studied at the bus terminals in Chonan area. The mean levels of indoor and outdoor NO2 were 25 and 27 ppb, respectively; this difference did not have a statistical significance. The mean levels of indoor and outdoor SO2 were 21 and 23 ppb, respectively. The higher levels of NO2 and SO2 showed in local bus terminal than express bus terminal. The higher levels also exhibited in winter than summer.

In this study, 9 PC Rooms were selected to Assess the exposure to Indoor Air pollutants such as carbon monoxide(CO) and Total Suspended particulate(TSP). Indoor Air Quality of PC Rooms might be worse by smoking and vehicle emissions because the PC Room were generally located near roadway. Therefore, proper methods should be prepared to improve the indoor air quality in PC Room.
