To investigate the status of farmers health management for health promotion, and for checking the effect of village health care center during 1 year, 746 subjects were selected with cluster method in 8 provinces of Korea. The most frequent group was 40th of age (39%) : elementary school graduates (32%) The self-conscious of health status tested with CMI (Cornell Medical Index) questionnaire, the subjects in the village of health care center had lower health status than those of conventional village. The farmers living in the village with health care center had longer agricultural work (p＜0.05) and more frequency of spraying pesticides in the fields. The subjects of living the village of health care center were frequently exercise (34%) with health appliance use methods (30%), but the duration time of exercise was similar, Dietary habits and agricultural work condition were similar between two groups. For the fatigue recovery, steeping and bathing were most favorite methods, but exercise was lowest. It was significantly different between 2 groups the fatigue recovering methods, the subjects of village with health care center were more doing exercise (p＜0.01), less sleeping (p＜0.01) than those of conventional village. The working condition of self-estimated of farmers was not good, only 8.7% was thought pleasant condition. Of the various health factors, exercise, nutrition, and working situation would be more important. Considering on farmers exercise, it was very weak point for health management. The foundation and leading of the Farmers health care center was encouraged to farmers. For more effective operations, the experts education, easy and funny exercise program, and health promotion committee for administrators would be needed. The better systemic and continuous exercise programs should develop for associating livelihood. Funding for this project provided by the ministry of health and welfare of Korea.

Crop inputs in excess of the yield potential of the soil type reduce profitability and increase pollution problems from leaching and runoff. Inaccurate fertilizer and pesticide application can also result in profit loss. Current farming practices plan only for the dominate soil in the field. A government-supported program titled "Pilot village project for the environment-friendly agriculture" was proceeded from 1999 to 2001 to tackle the problems with which our agriculture is faced by introducing IPM, INM and others. The objective of this study is to consider the potential input savings of agricultural chemicals and economic feasibility of the project compared with the conventional farming. The results of the analysis indicate the followings: (1) organic or no-pesticide farming size was increased from 9% in 1999 to 20% in 2001 ; (2) crop yield was a link bit lower than that of the conventional farming, but the sal6 price, gross income and income of the pilot village were 6%, 10% and 9% higher than that of the conventional farming, respectively; and (3) fertilizer and pesticide use also showed decreasing trend gradually.

Among many UNESCO world heritage sites in Korea, "Historic Village: Hahoe" is adjacent to Nakdong River and it is imperative to monitor the water level near the village in a bid to forecast floods and prevent disasters resulting from floods.. In this paper, we propose a recurrent neural network with multiple hidden layers to predict the water level near the village. For training purposes on the proposed model, we adopt the sixth-order error function to improve learning for rare events as well as to prevent overspecialization to abundant events. Multiple hidden layers with recurrent and crosstalk links are helpful in acquiring the time dynamics of the relationship between rainfalls and water levels. In addition, we chose hidden nodes with linear rectifier activation functions for training on multiple hidden layers. Through simulations, we verified that the proposed model precisely predicts the water level with high peaks during the rainy season and attains better performance than the conventional multi-layer perceptron.

The study is about the process of modernization of conventional rural houses in Kyung-gi province. It alms to identify the pattern of change, particularly focusing on the changes of the site plan and plan. The site of study is Samga Village, in YongIn County, near Seoul. The study discusses the process of modernization during the three decades from 1960 to 1980. The basic information was obtained through field research and site analysis, and the study relies predominatly on observational and statistical analysis. Four developmental stages can be clearly identified which are ; (1) Traditional type, (2)Modified-traditional type, (3) Saemaul type, and (4) The type of urban houses. The analysis was done through identification of changing site plan and plan. It is interesting to note that the changes of these elements show a certain pattern of sequential steps which also can be classified according to the four developmental stages mentioned above. The pattern of site design was consistantly maintained while plan and building system became very different However, the process of modernization of Korean rural houses was the process of producing a certain type of architecture that is not universal but uniquely Korean.

Of the total economic loss caused by disasters, 40% are due to floods and floods have a severe impact on human health and life. So, it is important to monitor the water level of a river and to issue a flood warning during unfavorable circumstances. In this paper, we propose a modified error function to improve a hydrological modeling using a multi-layer perceptron (MLP) neural network. When MLP's are trained to minimize the conventional mean-squared error function, the prediction performance is poor because MLP's are highly tunned to training data. Our goal is achieved by preventing overspecialization to training data, which is the main reason for performance degradation for rare or test data. Based on the modified error function, an MLP is trained to predict the water level with rainfall data at upper reaches. Through simulations to predict the water level of Nakdong River near a UNESCO World Heritage Site "Hahoe Village," we verified that the prediction performance of MLP with the modified error function is superior to that with the conventional mean-squared error function, especially maximum error of 40.85cm vs. 55.51cm.

This study was carried out to investigate the changes of rural residential environmemts accompanied by the rural village improvement projects. The results of this study can be a guidoline for further betterment works of rural village envirnments. This sutdy is composed of the survey of two major parts, one Is the interview of the residents and the survey of existing conditions of residential environments, and the other is a questionnaire survey of the mental image, preference and satisfaction for each village residential environments. Based on preliminary investigation, five rural villages, located In Kyungsamgun., Kyungbuk province, were selected as sutdy sites. The major results are summarized as follows; 1. In socio-cultural enveronments, the ratio of compound and non - agricultural household are increased with the modernization of rural villages. On the ocher hand, the numbers of neighbor's association are considerably decreased. This means the traditional community of korean rural villages are diminishing. 2. In physical environments, the ratio of improved western type gouses are increased In modprnized villages. And the modernization is most remarkable in the palls of fences and gardens. 3. By the result of the analysis of residfnt's environmental image and preference, the image scores of urban, formal, mdoern, etc. are showed to be high. And the preference is also high in modernized villages. But in general, the Preference for the village environment is comparatively low in all villages. This means the improvememt work should be continuous and systematic. 4. By the result of stepwise regression analysis, the variables, affecting the preference of village environment. are regularity, familiarity, amount of greenery, beauty of surrounding scenery, convenience, cleanness, etc. The R2s of the perference models were 0.4486 ∼0.9395, Which are considered to be high. 5. In the satisfaction for each residences, the toilets are mostly dis - satisfying. With the modernization of vilelages, the needs for environmental quality by residents are increased. 6. In the satisfaction for village enveironments, the satisfaction level is most low in service facilities, such as public bath, barbershop. And the satisfaction for the scenic beauty, the amenity of surrondings, and the com munity of the traditional villages, are commparatively high in conventional villges. 7. The imporvement works, based on the characteristics of each rural villages, are recommended. And the tradition of Jung - ja tree spaces and harmony with surrounding landscape of traditional villages, must be conserved with good regards.

The drastic change of mountain community, which have led existing villages to a size reduction or an extinction, makes this study concentrate on finding out the new community unit as a spatial zone of dayily life and agricultural production. The communality which has played a key role in a aura settlement consistency has been focused on the socio-economic aspect till now, neglecting the spatia] nature. The settlement-communality( SC) putting a stress on the spatial aspect can be, therefore, shapec as being multi-dimensional, composed of both a horizontally areal coverage on the surface of the residential place and a vertically hierarchial relationship between settlements, by analyzing thro( elements of communality that are the economic, socio -cultural and spatial activities. The research site is located administratively in Milan-Myoun, Pyoungchang-Gun, Gangwon-Do that ha: the characteristics as a typical mountain community. The results of field survey of which the method i: to draw the activity zone from an interview with every village's head and some residents with th( prepared questionaire can be summarized as followings. Firstly, the SC in almost all villages tended to be weakened or extincted, none the less, the spatia zone of that overally enlarged and got out of natural village unit(hamlet). However the areal coverall on which the SC has an influence reaches up to the alliant domain of a few villages generally congruen with the lowest level administrative district, Secondly, the economic and social activity pattern in village life has a tendency to be directly linked with a upper central place, so that has induced the function of a central village in the middle-low settlement hierarchy to be largely shrinked. Not only the conventional residents'access to goods service but also the recent service-delivers'access to residents has gradually formed the vertical communality with direct linkage between the upper and the bottom level settlements Lastly, the enfeeblement of the SC in the lowest settlement level tends to be supplemented by enlarging the horizontal zone of the SC or especially by strengthening the vertical direct linkage system. The very this point makes the mountain community open to the external world and also makes the spatial unit of community be multi-dimensional just like a cubic.

Since 2000 country region developmental policy has been to integrate not only the improvement of physical living environment but also various subjects on ecology, environment, scenery, local culture, and green tourism. This study has recently established a decentralized Rainwater Management plan in order to provide an hydrology cycle system to the eco-village being planned by Seocheon-gun as a part of the garden village development business promoted by the ministry of agriculture and forestry. Hydraulic conductivity of the subject area is measured at $10^{-7}{\sim}10^{-10}m/sec$, and a flowerbed-type rainwater Infiltration system capable of controlling a non-point pollution source that stems from the development-caused impermeable surface has been applied. In the case of rainwater flowing out from the main entrance way and parking lot within the complex being treated in the flowerbed-type rainwater infiltration system, natural purification effects via soil and plants as well as natural water cycling effects through evaportranspiration and infiltration are expected. The significance of this study, compared to conventional decentralized rainwater management being applied limited to the urban areas, is that it offers appropriate rainwater management planning based on the analysis of the current situation of the subject area. Decentralized Rainwater Management is a valuable measure both economically and ecologically that reduces the burdens on local underground water cultivation as well as rain water pipe lines or purification systems, and sewage pipes.

Along with fusion energy, photovoltaic solar energy conversion has long been considered as one of the few sustainable options for large scale energy supply in the future. In the past, commercial use has been restricted largely to remote area applications where conventional electricity is expensive. However, 1998 marked a year of transition where the major application of the cells changed to become generation of residential electricity in urban areas already supplied by the conventional grid. The current state of the technology is discussed as are major overseas programs to accelerate the urban residential use of photovoltaics, particularly in Japan, Europe and the United States, includng the "million roof" program in the latter. Finally, the planned use of photovoltaics in the Sydney 2000 Olympics is described, where the technology will be used to provide most of the electricity requirements of the 665 residences which will be a legacy of the Olympic Village.
