In order to give back-to-farm residents the stable settlement environment in the rural area, the 'community village' is desirable as the village type and its village planning guideline should be supported as well. The purpose of this study was to develop a guideline for the planning of back-to-farm community village in the living and social environmental aspects, based on the comprehensive comparative analysis about items that field survey and literature suggested. The guideline for the living environment was developed for 6 items; village structure(adequate size, lot, outer space for household), village landscape(allocation, space composition), road system and transportation(parking lot in village, placement of bus stops, village trail, public transportation, road and pedestrian system), common living facilities and common space(number, size, location & placement, plan type, planning type of common facilities), transfer space, individual housing(type, size, planning type). The guideline for the social environment was developed for 3 items; village making and establishment(resident participation type, resident participation tool, residents' construction participation) and resident education in the course of planning, resident participation(gathering resident opinion, decision making, composition of construction committee, community newsletter).

The purpose of this study was to develop guidelines for sustainability of back-to-farm community village in 4 aspects; social environment, maintenance and management, regional environment, and economic environment. These 4 aspects, which count for sustainability, based on the comprehensive comparative analysis about items that field survey and literature suggested. Conclusions of guideline are of the following. The guidelines on social environment are developed by 3 items; resident participation and activity, village leader, decision making in village and person in charge of operation. The guidelines on maintenance and management are developed by 5 items; village operation system, village regulation, transparency of management, village operation expenses, and management type. The guidelines on regional environment are developed by 2 items; support by central and local government, and area projects and connection to regional resources. The guideline on economic environment is not developed due to low demands of based production facilities and income increase facilities.

The purpose of this study is to suggest the spatial model which can be applied to the tourism farm plan. This study includes : (1) the analysis of existing facilities and activities of 22 tourism farms in Kyunggido and (2) the survey questionnaire about user's attitudes in 3 tourism farms. The results can be summarized as follows : 1) The .Major activities in the tourism farm are the resting/playing based on the natural environment and group meeting. 2) Average area is 17879.4uf (5418 坪). The most frequent facility is restaurant and lodge. 3) It is necessary to propose various types of tourism farm considering both natural conservation and development of rural region and users'various wants. The tourism farms are officially classified into four types Natural education type, Mind and body training type, Weekend farm type, Recreation type. 4) The space for tourism farm is divided into an area of production, and area of processing, and an area of convenience/recreation. 5) It is desired the convenience facilities are located in front of a farm, and the area of production is located at the back of a farm, and simple rest facilities are located all of the farm. 6) The weekend farm model and processing/convenient facility model are proposed in this study. Three types of the weekend farm models are proposed - simple type, composite type, and garden type. Three types of the processing/convenient models are proposed one building type, adjacent building type, and scattered building type.

Purpose: This study is to investigate the low back pain, social support, impediment in daily living activities and to identify factors affecting impediment in elderly farmer' daily living activities. Methods: The participants were 128 elderly farmers who had received nerve block. Data were collected using a structured questionnaire from February to March, 2018. They were analyzed using t-test, ANOVA, pearson's correlation coefficient, and linear multiple regression. Results: The score of low back pain was $6.27{\pm}1.69$ (10 points), that of social support $2.92{\pm}0.76$ (1~5 points), and that of impediment in activity of daily living $2.01{\pm}0.82$ (0~5 points). Factors affecting impediment in activity of daily living were found to include age (p=.017), daily hours of farm work (p<.001), fear for the nerve block (p<.001), low back pain (p<.001), and social support (p<.001); the explanatory power of these variables was 58.8%. Conclusion: This study has found the controllable factors affecting impediment in activity of daily living among the rural elderly engaging in farm work include low back pain, social support, and daily farming hours. Therefore, to reduce impediment in activity of daily living among them, it is necessary to develop nursing interventions that can improve impediment in activity of daily living through reduction of daily farming hours using local resources. It is also desirable to improve their health status by reducing low back pain, and develop and apply social supports with health education programs that fit the local resources and the needs of the rural elderly.

This paper present stabilization control of fixed speed wind generator by using variable speed permanent magnet wind generator in a wind farm connected with multi-machine power system. A novel direct-current based d-q vector control technique of back to back converter integrated with Fuzzy Logic Controller for optimal control configuration is proposed, in which both active and reactive powers delivered to a power grid system are controlled effectively. Simulation analyses have been performed using PSCAD/EMTDC. Simulation results show that the proposed control scheme is very effective to enhance the voltage stability of the wind farm during fault condition.

Jeollabuk-do has announced a future plan for the Saemangeum Wind Farm which includes the installation of fourteen wind turbines in a single line, located 500m back from the Saemangeum Seawall. It is anticipated as a positive effect that, for sea breeze blowing toward land, the average wind speed could be accelerated and the wind speed distribution could be uniformized by dint of the seawall, an upstream structure of the turbines. At the same time it is also anticipated as a negative effect that the strength of wind turbulence could be increased due to the flow separation generated at the back end of the seawall. According to the results of the computational fluid dynamics analysis of this paper, it has been observed that, at the 50m zone on the road surface located at the uppermost part of the Saemangeum Seawall, the average wind speed has been accelerated by approximately 6~7% and that wind shear has been decreased by 70%, but this positive effect disappears in the zone situated beyond the 100m from the back end of the seawall. It has also been observed that flow separation exists to a limited extent only below the bottom of the blade-sweeping circle and, furthermore, does not extend very far downstream of the wind. As a conclusion, it can be said that the seawall neither positively nor negatively affects the proposed Saemangeum Seawall Wind Farm layout.

Tidal flats develop along the south coast ofthe Korean peninsula. These areas are famous for sea farming. Specially, strong and coherent radar backscattering signals are observed over oyster sea farms that consist of artificial structures. Tide height in oyster farm is possible to measure by using interferometric phase and intensity of SAR data. It is assumed that the radar signals from oyster farm could be considered as double-bouncing returns by vertical and horizontal bars. But, detailed backscattering mechanism and polarimetric characteristics in oyster farm had not been well studied. We could not demonstrate whether the assumption is correct or not and exactly understand what the properties of back scattering were in oyster farm without full polarimetric data. The results of AIRSAR L-band POLSAR data, experiments in laboratory and JERS-l images are discussed. We carried out an experiment simulating a target structure using vector network analyser (Y.N.A.) in an anechoic chamber at Niigata University. Radar returns from vertical poles are stronger than those from horizontal poles by 10.5 dB. Single bounce components were as strong as double bounce components and more sensitive to antenna look direction. Double bounce components show quasi-linear relation with height of vertical poles. As black absorber replaced AI-plate in bottom surface, double bounce in vertical pole decreased. It is observed that not all oyster farms are characterized by double bounced scattering in AIRSAR data. The image intensity of the double bounce dominant oyster farm was investigated with respect to that of oyster farm dominated by single bounce in JERS-l SAR data. The image intensity model results in a correlation coefficient (R2 ) of 0.78 in double bounce dominant area while that of 0.54 in single bouncing dominant area. This shows that double bounce dominant area should be selected for water height measurement using In8AR technique.

Residential architecture was a lot more changed due to adopting modern residential type since 1960s. But people in farm houses are still living in a space of their past life causing a discrepancy. For this reason, the paper will identify the changed use for farm houses focusing on their plane views, and reason for the changed use as well. The result of this paper is expected to play a role for practical data to reasonably change and re-model farm houses located in back of cities such as Hyunpoong area. Targeted area for this paper, in order to survey change in residential environment due to industrialization and modernization, has narrowed down to 42 farm houses which are located Yuga-Myun, Hyunpoong-Gun, Dalsung-Gun where tradition and modern characteristics are harmonized being built before 1960s Researching relied on both documentary records and survey on the site, and survey on documentary records was performed in a way that preceding research for changed use of residential area was to be compared with people's farm houses in Kyeongsang-Do area, and survey on the site was carried out by photographing and land surveying and interview and analysis for them, and finally we acquired the result by analyzing use of interior for houses and plane view and relations between culture and social environment. From the result of this paper, there was a trend that farm houses had been improved function of a specific space by enlarging space and enlarged construction for inner rooms. And among spaces, kitchen and bath room was mostly enlarged its left side, and inner room had mostly enlarged its rear side, and kitchen was frequently enlarged in its side space. These kinds of variation in space is believed to be result of change of life style and house facilities

This study was conducted to evaluate seasonal effects on production performance of lactation sows reared in two different environments in South Korea. A total of 76 sows ($Landrace{\times}Yorkshire$) from the Dankook University experimental farm and 120 sows ($Landrace{\times}Yorkshire$) from a commercial farm were collected. In the current study, reduced (p < 0.01) feed intake and energy intake during lactation were observed in warm season compared with cool season in both farms. Sows in cool season had higher backfat thickness at weaning but lower back fat loss (p < 0.01) than those in warm season. The weaning to estrus interval was lower (p < 0.01) in cool season than in warm season. Piglets weaned in warm season had lower (p < 0.01) body weight (BW), body weight gain (BWG), and average daily gain (ADG) at weaning than did those weaned in cool season on the Dankook University farm, whereas the reduction effect was only observed during 0 - 21 d on the commercial farm (p < 0.01). Moreover, piglets weaned in cool season had higher BW, BWG, and ADG (p < 0.05) on both farms. In conclusion, our results indicate that warm season had very negative effects on feed intake and production performance of lactating sows and piglets.

The objective of this study is to analyze the relationships among support for farm village development work, farm village's brand equity and social and economic performance. The questionnaire was performed for 380 villagers in Jeollabuk-do Province. The surveyed data was analyzed by structural equation model analysis and Sobel test. Support for farm village development work such as living environment improvement project, income foundation creation project, rural tourism facilities project, and regional competency education project showed statistically significant positive effects on the farm village's brand equity. The farm village's brand equity also showed a statistically significant positive effect on the social and economic performance. The support for farm village development work such as living environment improvement project, village landscape improvement project, income foundation creation project, rural tourism facilities project, and regional competency education project showed no statistically significant effects on the social and economic performance. But, they showed statistically significant effects on the social and economic performance in indirect manner with the mediating effect of the farm village's brand equity. In this study, the effect factors on the farm village's brand equity and social and economic performance was verified in farm village development strategy, and then, it is meaningful to present the role and importance of support for farm village development work.
