This study examined the instability factor of real income and net profits of Chung-yang Green Pepper Farm through an analysis of the operating costs. Furthermore, this paper suggests a plan for stabilizing the price by shipment adjustments resulting from an analysis of the price elasticity by A Linear Approximated Inverse Almost Ideal Demand System (LA/IAIDS). The income instability factor of the farm based on an analysis of the operating costs was attributed to the unexpected loading of utility expenses and collapse of the price due to oversupply at a specific point in time. On the other hand, this is insufficient to completely explain the income instability factor of Chung-yang Green Pepper Farm because a price collapse does not include the monthly price changes. An analysis of the price and scale flexibility of Chung-yang Green Pepper Farm by monthly data showed that annual farm net yield increases by 1.21% due to a 2.21% increase in price if the shipment quantity is reduced to 1% a year. In summary, a plan that supports the farm price received through declining shipments in winter is effective in stabilizing the income of farms. Because Chung-yang Green Pepper in Gyeongnam region has an especially high market share of 82.5%, the prices and income of Gyeongnam Chung-yang Green Pepper farms can be stabilized effectively if they form an association of producers around the Gyeongnam region and adjust the shipment.

This study used the functions for public benefits as a standard for evaluating Green Tourism. By referring to the existing literature, the "function of building emotion", the "function of providing a natural environment", the "function of preserving traditional cultures", and the "function of maintaining the local community" have been selected as the measuring variables. Detailed sub-variables of each function were prepared to examine and analyze the recognition of these are the part of Green Tourists. The Green Tourists of Yangsuri in Yangpyeong, Sinnonri in Yangpyeong, and Jurokri in Yeoju participated in the survey for which 13 variables were used as measurement. The results are as follows: First, Green Tourists recognize farm villages as places for rest and relaxation and they laid great importance on the function of providing access to the natural environment. Secondly, out of the 13 measurement variables, "beautiful scenery in farm village", "making a contribution to village income", and "trust in agricultural products" greatly influenced the overall evaluation of Green Tourism. Thirdly, regarding the relationship between the functions for public benefits and Green Tourism, it was found that "facilities and activities for experiencing farming", "facilities for rest", and "beautiful scenery in farm villages" are closely related to building the emotion experienced in these villages, and that "cultivating environmentally-friendly agricultural products" and "beautiful scenery in farm village" are closely related to the function of providing access to the natural environment.

In this research, the concept of a salt farm parallel solar power system, which produce salt and electricity at the same site, is proposed for the first time in the world. The concept is that large waterproof plates made by interconnected solar modules are installed at the bottom of the salt farm. The pilot system was successfully installed at a sea shore, and verified its feasibility as a solar power plant. For deeper understanding, simulations for power prediction of the system were carried out and compared with the field test results. The power generation of the salt farm parallel system is comparable to conventional solar power plants. The cooling effect by sea water contributes more to the increase in the crystalline silicon photovoltaic module performance than the absorption loss due to sea water by maintaining certain height above the module.

This study was carried out to analyze the effect of the farm management and productivity increase of cabbages growing in the plastic house based on application of green manure crops such as silage corn, haussolgo (Sorghum bicolar L. Moench), hairy vetch, etc. According to the effect of green manure crop grown in summer season, the biomass amount of the silage corn was the highest; 7,630 kg per 10a, the next was haussolgo, 5,620 kg per 10a. In terms of the fertilizer ingredients, the first of forage soybean was 3.84% of nitrogen, whereas hairy vetch was 1.74% of phosphate and kalium, 4.74%. Productivity increase of cabbages was the highest in the haussolgo plot of which the yield of showed 10,090 kg per 10a and the farm household income would be worth 8,053 thousand won. By growing forage crops in the winter season, the biomass amount was the highest in the mixed sowing plot with rye (50%) and hairy vetch (50%) of 3,590 kg per 10a, whereas the productivity in the mixed seeding with rye (70%) and hairy vetch (30%) was highest, 6,249 kg per 10a and the farm household income would be worth 7,387 thousand won. Judging from these results, more practical on-farm research on applying different green manure crops as a basal fertilizer with cabbage in the plastic house should be considered to analyze the farm management and the farm household income at different sites.

Green tourism has recently focused on an alternative plan for activating a rural economy and coping with an income inequality between urban and rural areas. The Rural Development Administration has supported farm restaurants with the aim of increasing the income of farmers, determined unique native local foods and developed programs based on the experience rural life since 2007. Farm restaurants, which are the new type of local food restaurants, have unique food and various experiencing programs that reflect their own regional characteristics. We would like to understand how the farm restaurants have been developed and what types of characteristics they have based on the currently operating farm restaurants. The management situations and value of farm restaurants as tourist attractions were investigated as well in the tools for rural development.

This study is aimed to define and classify GREEN TOURISM (GT) resources as the basis for rural sustainable development, and to analyze the current conditions of GT and applicable resources in Korea. For these purposes, a field survey about 24 rural villages in Japan and Korea is applied, accompanied by a questionnaire survey of 30 specialists, as well as a literature review. The results of this study are summarized as follows. The concept of GT has 3 important points: interchange between rural and urban residents, staying in villages, and residents' participation. GT resource are divided into 4 types: Agricultural, Ecological, Historical and Living resources in a space and activity program. In addition, the GT resources in Japan are more quantitatively abundant than in Korea, but Korean agricultural and ecological resources were more abundant relatively. According to the several methods above, 18 space and 14 activity programs were classified. Lastly, this study analyzed the applicable 32 Korean resources using the specialists' questionnaire survey. Among the space resources, ecological landscape, farm produce, farm-land, water, and historical landscape have higher applicability, but the applicability of sports, event, commemoration, and divine space are lower. Among the activity programs, farm produce, animal, plant, food&beverage, and living appliance have higher applicability.

This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.

In this study, the effect of water level and temperature on the power generation was investigated in a water tank with an aquavoltaic PV module to perform feasibility research for the development of salt farm aquavoltaic system. The silicon solar cell attached to the bottom of each water tank is a 1-cell mini module, and the underwater effects of the crystal phase (19.0~19.9% of single- & 17.9~19.9% of poly-crystalline) of the PV module were investigated, and power generation characteristics for water level (0~10 cm) and temperature (10~40℃) were analyzed. The deterioration coefficients according to the water level and temperature of each single- and poly-crystalline module were investigated at very similar levels such as, -2.01 %/cm and -2.02 %/cm, -0.50 %/℃ and -0.48 %/℃, respectively. Therefore, in salt farm aquavoltaic system, water levels need to maintain as low as possible, and heat-induced degradation is similar to those shown in general land, and no factors have been found to be affected by the underwater environment depending on the determination.
