This study is to develop a web-based integrated system for flow of agricultural products based on recent researches with engineering approach. The system stands on the basis of web for accessibility and usability. Three parts of the system consist of analysis of regional shipping characteristics using tank model, estimation of pallet load efficiency with Monte Carlo Simulation, a long term prediction of market price with reliability analysis. Besides a decision support module for selecting optimal shipping market is added through synthesizing techniques and spatial analysis using GIS and applied to Chinese cabbage of Pyeongchang in 2004.

Practically, it is very hard to investigate the rural villages in North Korea. The Korean rural village in Yanbian is proximate from North Korea and most of inhabitants of the village have been emigrated from Hamgyeong-Do and Pyeongan-Do. In this sense, it can be meaningful to study Korean villages in Yanbian is an alternative approach toward researches of North Korean rural villages. In this study, spatial characteristics of the Ryongsan village, Ryongjeong city was studied as a representative korean rural village in Yanbian. The Ryongsan village has been formed based on the traditional culture and custom of North Korea. The case of planning and design is provided through drawings of components for planning of rural villages based on the results of spatial characteristics analysis.

In this study the effect caused by limited storage lift of agricultural products for determining shipping amount can be analyzed by lst order autoregressive model based on cobweb theorem. Carrying capacity and auction price of upland-grown cabbage and garlic from 2000 to 2003 in wholesale markets were used for analysis. In result regression models of cabbage can not be used in verification periods although those of garlic approximately predicted shipping amounts in verification periods. It can be inferred that it is hard to control shipping amounts depending on price fluctuation for agricultural products which have limited storage life so cultivated areas and meteorological risk should be managed for stable price.

This study tried to construct a direction in regional planning concerning the structural relationship between the ratio of aged population and the industrial characteristics. We investigated this structural relationship incorporating the aged population index and the number of classified companies. We applied diverse statistical analyses to understand the relationship. We classified the number of companies to reflect regional industrial characteristics using the principal component analysis. We applied a multiple regression model to understand the relationship between these two indices. The aged population index represents the degree of being old divided by the ratio of juvenile population and aged population. We found that such industries as manufacturing, service, and conveyance increase the ratio of juvenile population. However, industries such as tourism, waterworks, forestry, agriculture and etc. have a positive effect on the aged population index. In addition to these findings, we believe that the efficacy of this study is the possibility that can be used as the basic data when central or local autonomous entities need to adopt rural development planning.

In this study, the longevity index was suggested for researches about social and environmental effects to human immorality and criteria for defining longevity area were developed using statistical analysis. Candidates indexes based on researches about the tend of human death ratio were investigated. As a result statistical analysis, ratio of population over 85 yearn old and over 65 years was selected as a longevity index. Statistical analysis on the longevity distribution at each district showed that 'eup' and 'myun' are appropriate spatial unit to study social and geographical characteristics of longevity. The spatial analysis using the ArcViewTM with the suggested index shows the time dependent variances of degree of immorality and spatial relationship between degree of immorality and human migration.

The purpose of this research was to develop evaluation index of regional development for producing potential values of rural regions besides agriculture on a commercial scale. Rural regions have potential values such as preserved nature and spatial advantages and so on. For regional development, potential values should be synthetically evaluated by objective and standard index for supporting decision. For evaluation of plural functions of rural regions, evaluation index of rural regions was developed based on rural amenity. Applicability of evaluation index was studied using GIS and natural break method.
