The purpose of this study was to analyze the effectiveness of injury prevention education on elementary school students. We are selected two elementary school in Tejeon, one was intervention school, the other was control school. Surveys were completed before the begining of the interventions in February in 1994 and again after their completion in July 1994. Intervention group was 284 students in pre-test and 218 students in post-test. And control group was 253 students in pre-test and 208 students in post-test. The results of this study was followed. 1. In the general characteristics of subjects studied, sex, mother education, father education, economic status, number of household, and traffic environment were not significant difference between intervention and control group(p>0.05). 2. The contents of injury prevention education that subjects wished to learn, were not significant difference between intervention and control group(p>0.05). Also the mothods of that were significant difference between intervention and control group in pre-test(p<0.05) but not in post-test(p>0.05). 3. Education in knowledge, attitude and practice of injury prevention was slightly effectiveness. Change in attitude of injury prevention was higher than in knowledge and attitude of that we guess that they require a lot of education in the pedestrian prevention. 4. Reative risk between intervention and control group in injury incidence was 1.53 in hospital-care students, and 1.43 in home-care children. Also relative risk of total injury incidence was 1.38, therefore we knew that injury incidence after education was reduced. 5. In the analysis of injury causes, pedestrain injury was remarkably reduced at hospital-care students in two group. At home-care students, two groups were high proportion in play injury. 6. In the analysis of injury places, intervention group was high proportion at near-the house in pre-test(35.4%) and at school in post-test(36.4%). And control group was high at inside-the house in pre-test(31.5%) and at near-the house in post-test(28.2%).

The purpose of this study was to investigate clothing behavior of women in Dae Jeon and to find out the relationship between clothing behavior and occupations. Measures selected for this study was‘Creekmore Scales of Eight Clothing Variables’, (Creekmore, 1966). The questionnaires were distributed to women in Dae Jeon including teachers, women working in a government office, women working in a company, nurses, women working in a bank, women working in a department store and the business center, technicians, women working in a merry making place, and house wives. For statistical analyses of the data from 400 respondents, F-test, and t-test were used. The results were as follows: 1. There were partially significant relationship between clothing behavior and occupations. The significant variables were modesty, comfort, approval, and dependence among the eight clothing variables. a) The group of highest interest in modesty and comfort was house wives and the group of lowest interest was women working in a merry making place. b) The group of highest interest in approval was women working in a merry making place and the group of lowest interest was women working in a bank. c) The group of highest interest in dependence was teachers and the group of lowest interest was nurses. 2. Partially significant differences were found in clothing behavior between a working women and house wives: The house wives were more interest in modesty, comfort, management. 3. Partially significant difference were found in clothing behavior between White-collar workers and Blue-collar workers were more interest in attention, approval, interest.

The researches on the environmental friendly buildings have carried out on the materials, environmental property, technical elements and etc., and various buildings with these green materials have built and under construction nowadays and became a new trend of the green building. And recently, new building technique which builds the wall with the soil and wood and very easy to construct (called M Earthen House) was introduced as the green building and rapidly propagated. But the research on the indoor climatic characteristics, the ability to control the environmental comfort and the influence to the human beings of these buildings are not sufficiently identified yet. In this paper, the indoor environmental characteristics and the temperature controlling ability of these buildings in summer season were measured and analysed by the Portable Indoor Air Quality Monitor(BABUC/A, LSI) measuring equipments, ana the subjective test on the thermal environment of the subjects were carried out to evaluate the thermal comfort. The results can be summarized as follows; 1) Compared to the outdoor dry bulb temp.($15.4{\sim}28.7^{\circ}C$), the indoor temp. was $19.5{\sim}26.8^{\circ}C$. It showed the temperature controlling ability of the M earthen house was outstanding. And the indoor relative humidity, compared to the outdoor($45.4{\sim}100%$), was $58.1{\sim}76.4%$, it showed the humidity controlling ability of the M earthen house was also outstanding. 2) The thermal environment was evaluated as 'comfort'(neutral-slightly warm) and the humidity was also evaluated as 'comfort'(neutral-slightly humid). So, the results of the physical and subjective evaluation on the indoor thermal comfort in summer season were 'neutral' and 'comfort' coincidently, it was confirmed that the controlling ability of the indoor temperature and humidity of the M earthen house was very excellent.

This paper adopts recently developed panel unit root test that is cross-sectionally robust. Cointegration test is also used to find whether regional house prices are in line with gross regional domestic production (GRDP) in the long run in Korea during 1989-2009. Based on the panel VECM and the panel ARDL models, we examine causal relationships among the variables and estimate the long-run elasticity. We find evidence of cointegration and bidirectional causal relationships between regional house prices and GRDP. The results of long-run estimates, using both fixed effect and ARDL models, show that house prices positively and significantly influence on the GRDP and vice versa. Together with these results, the findings of ARDL-ECM imply that there exists a long-run equilibrium relationship between house prices and regional economic variables even if there is a possibility of short-run deviation from its long-run path.

The purpose of this study was to analyze the wind force distribution on the two single-span arched plastic house depending upon the house spacing and wind direction, which may provide the fundamental criteria for the structural design. In order to specify the wind force distribution, the variation of the wind force coefficients, the mean wind force coefficients and the drag force coefficients were estimated from the wind tunnel test data. The results obtained are as follows : 1. At the wind direction of 90$^{\circ}$, there was a typical span interval at which the maximum negative pressure was occured at the edge of the inside walls. 2. In the consideration of wind loads, the wind force coefficients estimated from independent single-span arched plastic house should not be directly applied to the structural design on the double houses separated. 3. The average maximum negative wind force on the inside walls was occured at the wind direction of 90$^{\circ}$, and the variations depending on the span intervals was not significant. 4. The average maximum drag force was occured at the wind direction of 300, and the magnitude of drag force was more significant at the first house. As the distance between two houses was increased, the drag force was slightly increased for every wind direction.
