A cursory study of small mammals on and near five military compounds where Korean Hemorrhagic Fever patients had been reported indicated that Mus musculus was more closely associated with man than all other mammals ccmbined. Therefore, there is a greater probability that Mus musculus is associated with the disease than any other species. Rattus rattus was common in villages and farm houses but was not abundant on military compounds. The two shrews, Crocidura lasiura and C. suaνeolens were uncommon, but they were often found in close association with hemorrhagic fever patients. Other small mammals were rare or lived in such places as to come in contact with man rarely.

Up to date, the majority research on the major landscape elements in organic farming has been mainly focused on the practice of seeking efficiency. The problem is that this type of study contributes to polluting the agricultural environment and damaging the ecological circulation system. As an alternative, there is a growing body of research on organic farming, but it is not widely applied that research on how to manage the landscape considering the scenic characteristics of farming villages practicing organic farming. Therefore, this study was carried out in the conservative aspects of rural landscapes in order to effectively manage the landscape of organic agriculture and, intended to be used to maintain and preserve natural and ecologically harmonious landscapes by deriving management methods suitable for landscape elements targeting the major landscape elements of the organic farming complex. To carry out, this study performed the experts survey which is composed of 13 major landscape elements, including rice paddies and fields, monoculture and diverse crops, dirt roads, windbreak trees, accent planting, dum-bung(small pond), natural small river, natural waterways, plastic film houses, one-storied houses, and pavilion. As a result, Farm land was formed in a square shape, concentrated in an independent space, planted companion plants around the crop, and covered with plants to manage the borders. As for the surrounding environment, it was analyzed that the aspart road system circulating through the village, the evergreen broad-leaved windbreak forest around the cultivated land, and the accent plant located at the entrance of the village were suitable. The hydrological environment consists of Round small pond made of stone in an open space, natural rivers around the village, and natural channels around the farmland, and The Major facilities are suitable for greenhouses that are shielded by plants in independent regions, and wooden duck houses located inside the cultivation area are suitable and The settlement facilities were analyzed to be suitable for single-story brick houses located in independent residential areas, pavilion located with greenery in the center of the village, and educational spaces shielded with wood from arable land. If supplementary evaluation criteria suitable for the management of organic farming landscape are additionally supplemented based on the results derived from this study, It is expected to enhance the landscape value of ecologically superior organic farming.

As a part of investigation on causes of drop in egg production in domestic chicken breeding farm, bacteriological contamination on air, feed, drinking water and artificial insemination instruments of randomly selected three farms was surveyed. Total bacterial population in the air was very high in all of the chicken houses tested and was not significantly different among these farms . However, total bacterial counts in the air of the problem house having egg drop problem and colibacillosis was higher than normal house within the problem farm. Bacterial population in the assorted feed was low before or after administration on the normal farm while it was much more increased after administration than before administration on the problem farm. Bacterial population of the drinking water in the source of water supply was very low and has no differences among farms tested. Also, bacterial population in the normal farm was not significantly different between source of water supply and after administration. However, population of total bacteria and coliform bacteria after administration was increased. Bacterial population was much higher in the artificial insemination instrument of problem farm than normal farm. However, this bacterial population in the problem farm was decreased to those of normal farm after these instruments were sanitized.

This study was carried out for preliminary feasibility review to investigate work efficiency of chestnut harvest using yield net and to find a way to reduce the cost for purchasing and managing yield net. To this end, we conducted a survey of 6 forest farm houses in Cheongyang, Gongju and Buyeo regions where yield nets are being used efficiently. Cost-benefit analysis based on Net Present Value and Benefit Cost Ratio was used to examine the investment profitability. While regions of Cheongyang A, Cheongyang B and Buyeo A are profitable in spite of no subsidy for purchasing yield net from the government, the regions of Gongju A, Gongju B and Buyeo B are not profitable without subsidy. When an 80% of subsidy for purchasing yield nets is provided, the forest farm houses in Cheongyang A, Cheongyang B, Buyeo A and Gongju B regions are found to be profitable while those in Gongju A and Buyeo B regions are still not profitable. We consider that the different results come from the differences in the planting method of chestnut, labor efficiency, labor skill and the orchard conditions such as slop. Finally, several efforts for government and cultivator are suggested to expand the use of yield net; planting chestnut in line, establishing installation and management methods, supporting the cost for purchasing yield net and studying detailed effects besides profitability issue.

Watering operation for oyster mushroom growing houses is regarded as drudgery and time consuming farm operation for growers. Most of mushroom growing beds in oyster mushroom growing houses are designed as two-row with four floor beds, therefore the watering and ventilation between the bed floors are much difficult for farmers because of its structural design. The study aimed to reduce the watering operation and improve the mushroom growing environment through the humidification and air supply on mushroom growing beds. Results showed that appropriate size of nozzle is between 0.8~0.5ml/s for the humidification and higher than the 2.0ml/s for the watering. The optimum water supply pressure was regarded as between 1.0~2.0MPa and the uniform distribution of droplet on the bed showed on air flow speed of 14m/s. The prototype was equipped with twin nozzle with. the humidification nozzle of 0.85ml/s and watering nozzle of 5.0ml/s, and the air blast fan with the air speed of 10m/sec in each air spout. In the field test in a practical scale mushroom growing house, it was well operated dependant on the set desire by a electric control unit. The machine can be practically used as air blast watering and air blast humidification for oyster mushroom growing farms without manual.

This study focuses on the regional characteristics observed in the composition and floor plan of folk houses in the Young-cheon region situated in the Southern East inland of Gyungsangbukdo. According to the typical characteristics of the Korean folk house, Young-cheon region is supposed to be classified as the Young-Nam region. Our study shows that the open inverse 'ㄱ' type composition is the most common among others, which consists the living room, UtChae and one BoosokChae that serves as a living room and a farm shop. The typical floor plan is called 'Young Nam type' 'H$\hat{o}$tjib' composed of four rooms. Young Nam type of house has a wall in front of the room floor with a door to make the space with the room floor as the internal space. This can be explained by the climatic conditions in the Southern region of Gyungsangbukdo, which has a very cold winter and has a harsh spring wind in Young-cheon. The structural feature to which we should pay attention is the Young Nam type house has a gambrel roof. The evolutions of the house in the 70s are observed in the roof during the Saemaeul Movement from a hut to a modernized roof. In the 80s, the replacement of the heating system, expansion of rooms, modernization of kitchen, replacement of paper windows, modernization of roof, and construction of amenities had taken place to change the space, construction and structure following the modern house features.

This study aims at explaining locality of living space which is changing drastically by exploring change of land utilization, living space and condition in Yeo-ju, an agricultural area around Seoul. The conclusions are as follows. 1. Agricultural land utilization tends to decrease, while civic land utilization tends to increase. 2. Change of living space due to transportation development is remarkable. Big ferry town (Yeoju-town) grew to a city, while small ferry town fell away. 3. In villages on slow urbanization, houses or lands are deserted. 4. In villages, there has been increasing number of recreational farm for urbanite. 5. In 80% of villages, there has been an increasing number of part-time farmers. 6. Most serious social problem in Yeo-ju is incompetence in agricultural activity after UR. In sum, Yeoju is now an area where the pace of urbanization is very tardy. However, this area, as an changeable area just before speedy urbanization, is expected to be urbanized drastically on condition that transportation develop. When plans suitable for this town are set up, Yeoju is expected to be a comfortable city.

In the production of organic Panax ginseng, the morphological changes were confirmed by providing general water and microbubble water, respectively. Analysis of seedling ginseng treated with general water and bubbles water revealed that many seedlings were formed in the seedling treated with bubble water, and about 15% weight increase occurred in the growing period. The growth rate of stem, leaf, and root was about 15% higher than that of all. Taken together, the growth of seedling cultivation using bubble water was about 15% overall. In order to process ginseng, the dried ginseng was higher in dry weight than the general water seedling seedlings grown in bubble water. This suggests that more processed products will be produced per unit weight at the time of producing the processed products at the farm, which can directly increase the farm income.
