Recently the use of smart phones and mobile devices is increasing rapidly, data search and retrieval in the mobile environments are generalized. There are only few mobile applications available in the area of agriculture while huge amount of new applications are developed and uploaded. The purpose of this study was to develop the android based mobile application for providing agricultural infrastructure and disaster information. The mobile application was designed through the database establishment and management system, server management system, and mobile application development. The database is composed of weather data, agricultural infrastructure data, and agricultural disaster data. By developing the mobile application which provides agricultural infrastructure information, it is expected to improve the accessibility to agricultural information and mitigate the agricultural disaster damages.

This study were performed to find the cooling effect and to provide design data during summer season for the Pad& Fan system of greenhouse . The temperature variation along the greenhouse width were analyzed. Also, the effect of the pad location and fan capacity on the cooling of the greenhouse were analyzed. While Pad &Fan systems were operating the temperatures in greenhouse were very different along the meausring locations. It is recommeded that PAD location and FAN capacity should be considered to design the Fan and Pad system in order to provide greenhouse the optimum temperature condition.

As the importance of renewable energy diffusion spreads, promotion of sustainable renewable energy projects such as agrivoltaics is expected to accelerate. Furthermore, to promote agrivoltaics projects, it must be considered the legislation related to agrivoltaics and Chungnam Province's local policy. This research focuses on the selection of the most suitable sites for agrivoltaics installations in Chungnam Province in South Korea. Therefore, the process of this research was as follows. First, the legislation related to agrivoltaics and local policy in Chungnam Province were identified. Second, it employs an analytic hierarchy process (AHP) to consider important criteria and their weights for site selection. Third, based on the weights calculated AHP, geographic information system (GIS) was performed to select most suitable location selection of agrivoltaics installations in Chungnam Province. The analysis identified approximately 60 promising most suitable location for agrivoltaics installations in Chungnam Province, primarily in the northern part of Chungnam Province. These areas are expected to meet electricity demands in nearby regions since these are relatively adjacent to Gyeonggi Province. According to the results of research, policy suggestions related to agrivoltaics were presented separately into the agricultural sector and the electricity power sector. The study's results serve as a valuable resource for future national-level candidate site selection for agrivoltaics projects.

Location patterns of protected horticulture were analyzed using a multiple correspondence analysis(MCA). The analysis could be used in evaluating location suitability of protected horticulture. The location factors of the protected horticulture for MCA include land category, size of protected horticulture, land slope, topography, effictive soil depth, irrigation and drainage condition, distance from roads, and so forth. The results showed that there were three different location patterns of protected horticulture. The first pattern was characterized by their nearness to villages. The facilities of this pattern were mainly located near to residential area. The second pattern was of those found in plain area. The facilities of this pattern were large in scale and located in paddy field far from residential area. The facilities of the last pattern were small in scale and located on nonpaddy fields. They were mostly found in hilly or mountainous area.

It is necessary to evaluate the location suitability of protected horticulutre facilities to guide and/or plan new protected horticulture facilities in rural areas. In this study, as one of methodological approaches for objective and systematic evaluation of location suitability for protected horiculture, the evaluation model of location sutitability for protected horticulture was formulated using AHP (Analytic Hierarchy Process) as a base technique. The evaluation model was made in three different selected regions ; suburban, plain, and mountainous, The results showed that there were significant differences in evaluation model of location suitability for protected horticulture among three regions.

본 연구는 전통적인 농업입지론에 기초한 생산지향 모델에서 시장원리를 고려하여 토지이용에서 변화와 농작물 가격의 변화를 고찰하기 위한 이론 연구이다. 본 연구에서 제시된 균형모델은 생산비용, 운송률, 수요의 측면에서 생산지향모델과 비교된다. 시장(도시)의 규모가 농업토지이용에 미치는 영향을 시나리오를 통해 분석하였다. 또한 제시된 균형모델이 농업에서 불확실성이란 요소를 그 모델에서 어떻게 수용하는가를 제시하였다.

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.

It is prescribed for the controls layout of agricultural tractors to offer a comfortable workspace in ISO 4253 as international standard. To export other country to the Korea agricultural tractor, it needs to come up to the nation standard. The objective of the study is to investigate for location of control operation of the Korea agricultural tractor after applying the ISO 4253, to know whether it suits or not the nation standards with the tractor of product and supply within the country. As the research result of Korea agricultural tractor, Controls position of them are few in zone of comfort which defined in ISO 4253 and escapes lots in the zone of reach.

Through 3D seepage analysis of pressure relief well installed on the embankment of agricultural reservoir, the effects of reducing pore water pressure and hydraulic gradient, and increasing piping safety, depending on diameter (0.2, 0.4, 0.6 m) and space (10, 25, 50 m) of relief well, were analyzed. The conclusions drawn through this study are as follows. i) At the location of pressure relief well, pore water pressure decreases by 25.3~62.5%, and hydraulic gradient decreases by 22.4~55.7%. ii) Between relief wells, pore water pressure decreases by 2.7~40.3%, and hydraulic gradient decreases by 2.8~47.0%, which are relatively less than at the cross section of installed location of relief well. iii) Piping safety factor by critical hydraulic gradient increases by 28.9~125.6% at the location of relief well and increases by 2.9~88.8% between relief wells. iv) Seepage analysis needs to be performed by the 3D method to make evaluation of seepage at the location of relief well and between relief wells possible. v) Additional evaluation is required for various conditions such as waterhead, engineering characteristics of embankment body and its foundation, location, diameter, spacing and depth of pressure relief well.

The objectives of the study were 1) to make the reasonable standard, 2) to select the objective and scientific method and process for the location-allocation of a new provincial capital city. The Main standard of location-allocation were suggested as follows ; 1) Integration of province 2) Convenience of Administration service 3) Accomodations of new provincial capital city 4) Balanced development by region. The validity of location-allocation were reviewed the population potentials and nodal accessibilities. The population potential was examined to find the maximum point of administrative demand, and the locationallocation model was examined to find the minimum point of the aggregated travel-cost to a proposed provincial government office. The nodal accessibilities measured in travel-time distance and actual values. Two major concerns in locating public facilities are efficiency and equity.
