Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.

The purpose of this study is to present a standardized scheme for providing agriculture-related information at various spatial resolutions of satellite images including Landsat＋ETM, KOMPSAT-1 EOC, ASTER VNIR, and IKONOS panchromatic and multi-spectral images. The satellite images were interpreted especially for identifying agricultural areas, crop types, agricultural facilities and structures. The results were compared with the land cover/land use classification system suggested by Ministry of Construction & Transportation based on NGIS (National Geographic Information System) and Ministry of Environment based on satellite remote sensing data. As a result, high-resolution agricultural land cover map from IKONOS imageries was made out. The results by IKONOS image will be provided to KOMPSAT-2 project for agricultural application.

Based on the real-time monitoring by remote sensing and dynamic management by GIS on agricultural land and water resources in arid area, we solved the practicability and popularization of small-scale spatial information service system. Through demonstration, the standards of spatial information service database of agricultural land and water resources is set up, and the agricultural land and water resources management system in Shehezi City of Xinjiang Autonomy is established, which provides periodically the spatial information services needed by agricultural production to support for sustainable development in arid area.

A Web-based information system from the Korea Agricultural Water Use Laboratory AWUL, has been developed to provide with regional water management information and guidance for the operations of irrigation reservoirs through the World Wide Web(WWW). Twenty-six reservoirs are selected as the reference reservoirs for regional water management , and the real-time operation guide may be issued the grwoing seasons. The information available from the system includes the wether forecasting , drought analyses, and reservoir operation data for those reference sites. For a specific reservoir, the manager may access the system to obtain the water requriement, irrigation secheduling , and reservoir operations that fit best to the irrigation district.

In this study, it was developed and verified an application method of fuzzy-logic theory to the rating process of agricultural fill dam safety. A fuzzy-logic is very famous logical system when some decision making is made on the status of a lack of information. Three proxies were selected and configured membership functions (MFs) and these MFs were activated in the process of fuzzification procedures. Fuzzified vlaues were passed through the rule-based inference system, then fire strength could classified among cases of the rule-based inference system. To obtain final results, Mandani-type was adapted in the defuzzification process. As the results, it was shown the developed system can give a correct results that was compared with Matlab - fuzzy inference function. More ever it could perform the detailed analysis and improvement on the infrastructure safety rating process using classical diagnosis method.

The information on agricultural weather over the Korean Peninsula was produced, using the Bio-sphere-Atmosphere Transfer Scheme(BATS). We modified the input and output portions of BATS such that the whole processes can be excuted as a package. Based on this approach, automatic production system of agricultural meteorology information was developed. The results of this model was compared with the observed data. The differences between the model results and observed data for surface temperature, rooting zone temperature and top soil temperature were 2.0$^{\circ}$C, 2.0$^{\circ}$C and 2.6$^{\circ}$C, respectively.

Coordination has been identified as a concern in the cross-cutting issues of food security and nutrition (FSN) in Cambodia. Food Security and Nutrition Information System (FSNIS) in Cambodia is the only "entry portal" to support policy formulation and decision-making with regard to FSN. While this knowledge and information management system has earned a respectful reputation, Council for Agricultural and Rural Development (CARD) faces many challenges in the implementation of the system. This paper will present how FSNIS has been developed and impacts on policy or strategy related to FSN. In addition, sustainability of the system is a key challenge for FSNIS; yet it is interesting to see how it works. Along with a success story, FSNIS is recognized by its stakeholders as the most successful knowledge and information management system in the field of FSN in Cambodia.

In this study , the system was developed for design procecure of agriultural engineering. For development of the system, design reports of Rural Development Corporation were analyzed, the components using in system were searched, and the user interface was developed. It was found that the development of this system would be used for design procedure using design information based on RDBMS.

The yield is basic and necessary information in precision agriculture that reduces input resources and enhances productivity. Yield information is important because it can be used to set up farming plans and evaluate farming results. Yield monitoring systems are commercialized in the United States and Japan but not in Korea. Therefore, such a system must be developed. This study was conducted to develop a yield monitoring system that improved performance by correcting a previously developed flow sensor using a grain tank-weighing system. An impact-plated type flow sensor was installed in a grain tank where grains are placed, and grain tank-weighing sensors were installed under the grain tank to estimate the weight of the grain inside the tank. The grain flow rate and grain weight prediction models showed high correlations, with coefficient of determinations (R2) of 0.9979 and 0.9991, respectively. A main controller of the yield monitoring system that calculated the real-time yield using a sensor output value was also developed and installed in a combine harvester. Field tests of the combine harvester yield monitoring system were conducted in a rice paddy field. The developed yield monitoring system showed high accuracy with an error of 0.13%. Therefore, the newly developed yield monitoring system can be used to predict grain weight with high accuracy.

Efficient use of scientific and technical information is indispensable for research and development. This study is aimed at new system design of Agricultural Information for RDA Library operation by an expeditious system for appropriate support of research activities through information service. Current Library management factors such as organization, budget, collections, staff. space, and information service was surveyed and user's requirements was also evaluated. In order of optimize the information system performance the new designed system was suggested as follows : 1) Existing dispersed library functions have to be unified as a whole 2) Library could be reorganize as a independent unit 3) Construction of inter-library network between libraries engaged in the same field highly recommand for the exchange of information.
