This study was conducted to investigate the nutrient intake, dietary and weight control behaviors and iron deficiency of adolescent girls. The subjects were 216 female middle school students living in urban and rural areas of Inchon. Thin cross- sectional study was conducted by questionnaires and data were analyze by SAS program. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program(CAN-pro). The mean height, weight. BMI and obesity index for the subjects were 158.2 cm, 51.1kg, 20.4 and -5.3 % in urban students and 155.9 cm, 49.3 kg 21.1 and -8.2% in rural students, respectively. Easting blood samples were obtained and analyzed for iron nutritional status. The mean obesity index of the urban students was higher than that of the rural students. The proportion of the overweight group was higher in urban students compared to rural students, However, over 10% of both area students belonged to the low weight group, respectively. Most students of both areas skipped breakfast and the main reason was on appetite and lack of time. Urban students were more concerned with body image. The nutrients which showed a lower mean intake as percentile of RDA were Ca, iron, vit A an Vit B$_2$ and most nutrient intakes of urban students were significantly higher compared to those of rural students. These results indicate that nutrient intakes in the female middle school students were considerably lower than the RDA. Also they had undesirable food habits and lower self-satisfaction with their body image, There were significant differences in the mean MCV, TIBC and serum ferritin between urban and rural area subjects. Mean Hb, Hct, MCH, MCHC and TS, bowaver, were not significantly different. Prevalence of iron deficiency greatly varied by indices from urban(11.5%) and rural (8.7%) when judged by Hb to urban(23.1) and rural (23.3%) by serum ferrition. Therefore, proper nutrition education is required for good nutrition desirable food habits, weight control, and guidance for iron deficiency in anemic female of adolescents.

The present study was conducted to evaluate nutritional intake by lunch-box of middle school girls who live in Chonbuk area. Anthropometric measurements and food intake from lunch-box over a three day period were investigated in a total of 110 middle school girls from rural (n＝37) and urban (n＝73) areas. The results are summarized as follows : 1. Not all the steamed rice in the lunch-box had enough mixed-cereal. 2. In the survey of food intake by food groups, 70.5% of the food came from the cereal group. 3. The intake of protein, phosphate, Vitamins $B_1 and B_2$, niacine and Vitamin E were adequate, however, the intake of other nutrients was significantly lower than those of one-third of the Korean RDA.4. Protein, lipid, and zinc intakes of the students from the rural area were significantly lower than those of students from the urban area. however, the carbohydrate and dietary fiber intakes of those in the rural area were significantly higher than those of the students in the urban area. 5. The percentage of calories from carbohydrate : protein lipid ratio was 67.6 : 12.2 : 16.9 for students in the rural area and 59.2 : 14.9 : 22.5 respectively for those in the urban area. In Summary, the intake of calcium, iron, Vitamins A, $B_6$, and D, folate and zinc from lunch-box in middle school girls was much lower than that of one-third of the Korean RDA. The intake of carbohydrate and dietary fiber of the students in the rural area was significantly higher, but that of protein, lipids, and zinc was lower than that of the students in the urban area. Therefore, nutritional education programs for both students and their parents should be provided to improve the daily food intake from lunch-box.

Handling the emergency problems such as Chemobyl accident require real time prediction of pollutants dispersion. One-point real time sounding at pollutant source and simple model including turbulent-radiation process are very important to predict dispersion at real time. The stability categories obtained by one-dimensional numerical model (including PBL dynamics and radiative process) are good agreement with observational data (Golder, 1972). Therefore, the meteorological parameters (thermal, moisture and momentum fluxes; sensible and latent heat; Monin-Obukhov length and bulk Richardson number; vertical diffusion coefficient and TKE; mixing height) calculated by this model will be useful to understand the structure of stable boundary layer and to handling the emergency problems such as dangerous gasses accident. Especially, this simple model has strong merit for practical dispersion models which require turbulence process but does not takes long time to real predictions. According to the results of this model, the urban area has stronger vertical dispersion and weaker horizontal dispersion than rural area during daytime in summer season. The maximum stability class of urban area and rural area are "A" and "B" at 14 LST, respectively. After 20 LST, both urban and rural area have weak vertical dispersion, but they have strong horizontal dispersion. Generally, the urban area have larger radius of horizontal dispersion than rural area. Considering the resolution and time consuming problems of three dimensional grid model, one-dimensional model with one-point real sounding have strong merit for practical dispersion model.al dispersion model.

평균수명의 증가로 은퇴 후 생활에 대한 관심이 높아지면서 쾌적한 자연환경을 찾아 귀촌을 희망하는 가구가 증가하고 있다. 본 연구는 전국 도시가구를 대상으로 은퇴 후 귀촌을 희망하는 가구의 사회경제적 특성을 고찰하고 임의절편 로짓모형을 이용하여 귀촌 희망 요인을 분석하였다. 주거실태조사 자료를 이용한 분석 결과 도시가구의 약 27%는 은퇴 후 귀촌을 희망하고 있으며 중간 소득층, 40~50세, 고등학교 졸업 가구주의 귀촌 희망 비율이 높다. 귀촌 희망 가구는 사회경제적으로 중간계층에 속하는 집단이며, 주택보다는 소음, 대기오염 등 주거환경이 귀촌 희망여부에 유의한 영향을 미치고 있다. 즉 은퇴 후 자신의 경제적 능력으로 쾌적한 자연환경에서 좀 더 여유로운 전원생활을 누리는 것이 귀촌을 희망하는 가장 주된 이유로 볼 수 있다. 또한 고령자 중 귀촌자가 많았던 도시에서 귀촌 희망 비율이 높게 나타나 도시민들이 은퇴 후 귀촌을 희망하고 실행하는 데 귀촌에 대한 정보 제공이 중요한 역할을 할 것으로 보인다.

Relations of urban heat island and air pollution are analyzed by using $SO_2$ concentration data (winter season in 1985) from 10 sites of Seoul area and differences of wind speed and air temperature in urban and rural area. Urban heat island is developed when daily mean wind speed at urban site is lower than 1.5m/sec or in the interval of 3.0 $\sim$ 3.5m/sec. When differences between urban and rural air temperature is greater than the overall average of those differences, $SO_2$ concentrations of those above-average differences are 1.3 $\sim$ 1.8 times higher than those of below-average differences. The trends are shown obviously at north-eastern area of Seoul (Gilum Dong, Ssangmun Dong, Myeonmog Dong). When intensity of Urban Heat Island is weak, $SO_2$ concentration was reduced in propotion to a rise of wind speed. But $SO_2$ concentration is on the partial increase in spite of a rise of wind speed when intensity of urban heat island is strong.

With the increasing number of migrants from urban to rural areas in Korea, Population inflow policies have helped increase the number of urban-to-rural migrants which has eased the labor shortage in rural areas.. But, there are new problems in rural areas caused by the "perception gap in regard to harmony, awareness, pride and opportunity to meet" between the urban-to-rural migrants and the original residents. The purpose of this study was to analyze the factors affecting the harmony between the urban-to-rural migrants and residents. A survey was conducted among 70 people living in Hongseong-gun in Chungcheongnam-do with an aim to come up with proposals for policies that can help resolve these social problems in the mutual understanding of urban-to-rural migrants and original residents. An ordered logit model was used to analyze the effect of the perception gap between the urban-to-rural migrants and the rural residents. The result of the survey showed that most of the urban-to-rural migrants believed that the increase in urban-to-rural migrants did not bring harmony to rural areas because of the perception gap. Based on these results, we concluded that the following three policy alternatives would be needed: first, development of urban-to-rural migrant education programs for relatively young men; second, a policy supporting various forms of community gathering in a rural society; third, diversification of urban-to-rural migrant education programs such as communication program and conflict management program, etc.

This study begins with a question of what spatial impact international trade policy would have following the Uruguay Round, particularly focusing on agricultural trade liberalization in Korea. Based upon the neoclassical urban economic model, it first identifies the channel in which agricultural market opening can ultimately affect both rural and urban are as; $\circled1$ Free trade will depress domestic price of agricultural products, $\circled2$ which will in turn depreciate agricultural land price. $\circled3$ The decrease in marginal supply cost for urban land will then facilitate urban sprawl, provided that the government relaxes restrictions on urban-rural land conversion. Theoretical analysis is further refined by empirical considerations that distinguish agricultural land value solely for production purpose from that for future urban, uses, and that distinguish the urbanization effect caused by the fall in the supply cost of urban land from that caused by the existing high level of demand. Utilizing the estimate of bid-price for paddy field derived from the revenue-cost relationship of rice production, simulation results show that the urban-rural boundary under trade liberalization can expand outward up to 70-85km radius in the Seoul metropolitan area, suggesting the emergency of a metropolis or even a megalopolis which extends from Seoul to the central part of the country. Since the geographic extent of urbanization effect can vary depending upon the urban spatial structure, however, it is recommended that the redevelopment option in the built - up area should always be tied up with the issue of whether to deregulate rural-to-urban land conversion.

본 연구의 목적은 농촌지역 쓰레기의 발생 및 관리실태를 도시지역과 비교분석하고, 농촌산업활동 유형별로 쓰레기 발생특성을 조사하여 향후 농촌지역의 특성에 적합한 쓰레기의 관리 및 처리시스템 설계를 위한 기초 자료를 제시하는데 있다. 농촌지역의 지역특성별 및 계절별 쓰레기발생 실태에 대한 현장조사 결과는 다음과 같다. (1) 도시규모별 1인 1일당 쓰레기 발생량을살펴보면 대도시일수록 소득수준이 높고 생활문화의 다양함과 복잡함으로 인해 발생량이 많으며, 군급 도시에서는 1995년에 1일 1인당 0.88kg으로 서울시민 배출량의 약 2/3수준에 지나지 않는 것으로 나타났다. (2)우리 나라 생활쓰레기의 처리 의존도는 매립처분, 재활용, 소각처리 순으로, 대도시일수록 매립처분에 의존하는비중이 크며, 군급 도시로 갈수록 소각에 의존하는 비율이 높았다. (3) 농촌 쓰레기의 물리화학적특성조사 결과 거의 모든 물리화학적 특성이 도시지역의 쓰레기와 그다지 차이를 보이지 않아 최근 농촌지역의 소비형태가 도시지역과 유사한 것으로 나타났다.

Though children are imperfect and immature in themselves, they have their own merits and characteristics, so that they should not be appreciated by the adult's own viewpoints. The needs of a child are obviously different from those of an adolescent or an adult. Therfore we should understand their mentality and psychology in order to give desirable outdoor space to them. In this study, children's view of outdoor environment was studied by analyzing the painting of object elementary school students of one and the other urbanizations and schooling years and different schooling years also. The data were drawn from 182 children of two different urbanization levels. The urbanization level was standardized with urban area(Taegu), and rural area(Jukjang - myon). According to the research, more area of garden was exprssed In paintings of urban children. House was expressed vy far more frequently in paintings of rural childrin than in those of urban dwellers. The children of urban expressed recreation facilities more frequently within their garden. It reflected the limitation of play space for them, As a result, the preference fur outdoor 7pare of children should by considered in Planning space for them.
