When modern farm houses were built, they were made up of only residential parts. So that many new accessory building-private residential room, toilet, warehouse, storeroom, barn, cattle pen and etc.-were made without any order around modern farm houses. This study is aimed at grasping how the process and contents of extension of the accessory building of modern farm houses have been changed, understands and explicates the reason why accessory buildings of modern farm houses were changed and bring forward better directions about accessory building of modern farm houses at Samchok seashore area of Kangwon Province. The way for it which be made good that the scenery of a rural district was ruined by accessory buildings distributes and develops various standard models about accessory buildings that they are becoming to modern farm houses.

This research is to establish a theme-type organic edu-farm model and provide ways to practically apply it so as to vitalize urban-rural exchange through the emerging concept of green tourism. This research also traces the practical development of organic edu-farm programs. Organic edu-farm(OEF) should be some of the ideas to develop organic agriculture resources according to the local features, and learn by direct and actual experience a life of organic farm. A few policy suggestions to put OEF model in practical use are proposed. What the state needs to do through direct involvement are to put efforts at demand expansion on organic farm products, to clean and beautify the green rural environmental settings, to build more urban-rural exchange facilities. What is more important, however, is financial support, to create the network and to develop program contents for each OEF operation unit. The OEF model proposed in this research will be applied as a relevant reference in planning and realizing sustainable green tourism at the village level.

The objective of this study is to investigate the commercializations and difficulties on the farm-food. For the activation of the farm-food, it is necessary to totally review the support of the government and prepare the supporting system like manual on the commercialization of farm-food that is helpful to the small farmers. It is also necessary to support small farms strategies customized for increase the sales and satisfaction on farm-food and build-up the promotion related to the green tour and/or farm experience. The results and finding of this study can be used to build-up the supporting system that reflects the rapid change of market and customer's preference. They can also be used to design rational policies that is helpful to the farm-food producers.

The purpose of this study was to analyze clothing expenditure patterns of urban, rural/farm, and rural/non-farm households. A sample of 23,994 households was selected from the 1996 National Survey of Household Income and Expenditure, and 1996 Farm Household Economy Survey. Frequency and regression analyses were used. Major findings were: 1) clothing expenditure of rural/farm households were significantly lower than that of urban and rural/non-farm households; 2) in terms of clothing expenditure by categories, urban and rural-non-farm households have similar expenditure pattern; 3) clothing expenditures relative to income were lower than 1 for all three groups; 4) clothing expenditures relative to total income for urban and rural/non-farm households were higher than 1, while that for rural/farm households was lower than 1; 5) a major factor explaining clothing expenditure differences between urban and rural consumers was the household head＇s occupation.

This study aims at shedding light on two questions: 1) how livelihood strategies hired by heterogeneous farm households differ and in what aspect, and 2) would the strategy change over time or remain identical across farm types? Using 2013-2017 Farm Economy Survey panel data, we divide the sample farms into 4 sub-groups based on income level and sources. Key findings are as follows. First, regardless of farm types, strong path dependency has been observed. That is, lots of farms are likely (enforced) to maintain the livelihood strategies, accounting for why many farms fail to response to market and/or policy signals. Second, along with compounding risks, farms are more vulnerable to specific sorts risks. Third, based on the findings, we made policy suggestions.

Background and objective: This study was conducted to compare the cultivation environment, growth of cut flowers, and management performance of conventional farms and smart farms growing the standard cut chrysanthemum, 'Jinba'. Methods: Conventional and smart farms were selected, and facility information, cultivation environment, cut flower growth, and management performance were investigated. Results: The conventional and smart farms were located in Muan, Jeollanam-do, and conventional farming involved cultivating with soil culture in a plastic greenhouse, while the smart farm was cultivating with hydroponics in a plastic greenhouse. The conventional farm did not have sensors for environmental measurement such as light intensity and temperature and pH and EC sensors for fertigation, and all systems, including roof window, side window, thermal screen, and shading curtain, were operated manually. On the other hand, the smart farm was equipped with sensors for measuring the environment and nutrient solution, and was automatically controlled. The day and night mean temperatures, relative humidity, and solar radiation in the facilities of the conventional and the smart farm were managed similarly. But in the floral differentiation stage, the floral differentiation was delayed, as the night temperature of conventional farm was managed as low as 17.7℃ which was lower than smart farm. Accordingly, the harvest of cut flowers by the conventional farm was delayed to 35 days later than that of the smart farm. Also, soil moisture and EC of the conventional farm were unnecessarily kept higher than those of the smart farm in the early growth stage, and then were maintained relatively low during the period after floral differentiation, when a lot of water and nutrients were required. Therefore, growth of cut flower, cut flower length, number of leaves, flower diameter, and weight were poorer in the conventional farm than in the smart farm. In terms of management performance, yield and sales price were 10% and 38% higher for the smart farm than for the conventional farm, respectively. Also, the net income was 2,298 thousand won more for the smart farm than for the conventional farm. Conclusion: It was suggested that the improved growth of cut flowers and high management performance of the smart farm were due to precise environment management for growth by the automatic control and sensor.

Background: Activation of peroxisome proliferator activated receptor gamma ($PPAR{\gamma}$) in the alveolar macrophages (AM) by selective synthetic $PPAR{\gamma}$ ligands, improves the ability of the cells to resolve inflammation. In birds, respiratory macrophages are known as free avian respiratory macrophages (FARM) and show distinct functional differences from AM. The effects of treating FARM with $PPAR{\gamma}$ ligands are unclear. Methods: FARM were harvested by lavage of chicken respiratory tract and their morphology assessed at microscopic level. The effects of $PPAR{\gamma}$ agonists on the FARM in vitro viability, phagocytic capacity and proinflammatory cytokine (TNF-${\alpha}$) production were assessed. Results: FARM had eccentric nucleus and plasma membrane ruffled with filopodial extensions. Ultrastructurally, numerous vesicular bodies presumed to be lysosomes were present. FARM treated with troglitazone, a selective $PPAR{\gamma}$ agonist, had similar in vitro viability with untreated FARM. However, treated FARM co-cultured with polystyrene particles, internalized more particles with a mean volume density of 41 % compared to that of untreated FARM of 21 %. Further, treated FARM significantly decreased LPS-induced TNF-${\alpha}$ production in a dose dependent manner. Conclusion: Results from this study show that $PPAR{\gamma}$ synthetic ligands enhance phagocytic ability of FARM. Further the ligands attenuate production of proinflammatory cytokines in the FARM, suggesting potential therapeutic application of $PPAR{\gamma}$ ligands in the management of respiratory inflammatory disorders in the poultry industry.

Farm themed restaurants is an initiation by the Rural Development Administration (RDA) in order to perpetuate and develop Korean traditional food-culture. This food business model contributes to the increase of local food consumption and non-farm income for rural communities. Thus, the purpose of this study was to investigate the visitor's expectations, perception and satisfaction on the farm restaurant management type in order to assist activation of farm restaurants. Farm restaurants were categorized into two types; restaurant style and experience style. The majority of subjects(67.9%) were experiencing their first time to dine at farm restaurants. Regardless of farm restaurant style, the subjects perceived that farm restaurants use high quality food ingredients. The degree of subjects expectations prior to visiting a farm restaurant was estimated by 7 Likert scales. The results show that most subjects had high expectations for using good-quality food ingredients such as ‘fresh food (restaurant style 6.25, dietary education style 6.02)’ and ‘environment-friendly food (restaurant style 6.07, dietary education style 5.91)’. Overall satisfaction of the farm restaurants was also high. The satisfaction of food scored 4.1 and the satisfaction of experience program scored 3.8.
