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.

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.

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(NO_2) and sulfur dioxide(SO_2) were studied at the bus terminals in Asan area. The mean levels of indoor and outdoor NO_2 were 36.05 and 33.70ppb, respectively; this difference did not have a statistical significance. The mean levels of indoor and outdoor SO_2 were 12.95 and 12.3ppb, respectively. The higher levels of NO_2 and So_2 showed in local bus terminal than express bus terminal. The higher levels also exhibited in winter than summer.

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.

아산지역 PC방에서의 CO및 TSP에 관한 연구

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.

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.

大氣汚染 疫學에 있어서의 暴露評價에 대하여

孫富順,朴鍾安 서울大學校保健大學院 1995 國民保健硏究所硏究論叢 Vol.5 No.2

「Total Exposure」의 개념에 기초하여, 大氣汚染의 健康影響 關한 疫學硏究를 再構築한다고 하는 시도는, 아직 시작한 단계에 불과하다. 지금까지 實施된 疫學硏究를 이와같은 暴露評價의 点에서 다시 보는것도 必要할 것이다. 暴露와 影響의 關連을 檢出할 수 있다는 感度의 点에서는, sample size와 誤分類의 問題가 Trade-off관계에 있는 것에 충분한 留意를 해야 한다. 엄밀한 意味에서는 Individual Exposure를 測定할 수 있는 Technology의 開發을 推進하지 않으면 안되지만, 한편으로는 質的評價와 量的 評價의 조합에 의해서 暴露評價를 精密化해 나가는 길도 探索할 必要가 있을 것이다.

Recent epidemiologic studies revealed that the concentration of air pollutants and fine particulated matter have some effects on health status and are associated with increased mortality and morbidity. The purpose of this study was to characterize background mass concentration of fine particle (PM2.5) and metallic composition from September 2001 to August 2002 in comparison with a medium city, Asan and metropolitan city, Seoul. Conclusively, proper management for fine particles was required in a medium city, Asan, considering the concentrations of metallic elements in fine particles in Asan were relatively higher than those in Seoul. The results were as followed. 1. Average mass concentrations of fine particles in Asan and Seoul were 37.70(±18.41 ㎍/㎥) and 5.83(±38.50)㎍/㎥, respectively. When the weather conditions were classified as normal and yellow-sand, measured average mass concentrations of fine particles in yellow-sand weather condition was significantly higher than those of normal weather condition in both cities (p<0.05). 2. Depending on seasons, measured average mass concentrations of fine particles in Asan and Seoul in spring were 47.76(±19.07) ㎍/㎥m and 61.53 (±4.37) ㎍/㎥, respectively. In summer, the average mass concentrations of fine particles in Asan and Seoul were 29.44(±9.85) ㎍/㎥ and 25.42(±8.10) ㎍/㎥, respectively. Especially, the concentration was the highest in spring and the lowest in summer among four seasons. 3. Average concentrations of manganese(Mn), iron(Fe), chromium(Cr), cadmium(Cd), lead(Pb) and silicon(Si) in fine particles in Asan were significantly higher in Seoul (p<0.05). Average concentration of Si in fine particle in Asan was statistically higher than that of Seoul during yellow-sand condition (p<0.05). 4. Considering the characterization of four seasons, average Pb concentration of fine particle in Asan is significantly higher than that of Seoul in spring(p<0.01). In summer, average Mn and Cr concentrations of fine particle in Asan is higher than those of Seoul (p<0.05). Average Mn. Fe. Cr and Si concentrations in fall (p<0.05), and average Mn, Fe, Cr, Pb, and Si concentrations in winter (p<0.05) in Asan were higher than those of Seoul, respectil'ely. 5. Mass concentrations of each Mn, Fe, Cd and Si in fine particles were significantly correlated with both cities. In normal weather condition, Mn, Cu and Si concentrations are statistically significant in Asan, while Mn, Fe, Cu and Si concentrations are statistically significant in Seoul. Mn, Fe and Si concentrations in both cities were statistically significant during yellow-sand weather.
