An areal elderly migration model (AEMM) was developed to assess the demand of rural development projects targeted towards elderly people. The AEMM was developed with adaptation of the gravity model to represent spatial interaction regarding amenities. Areal characteristics were classified for estimating the amenities from the perspective of net migration. From 1990 to 2000, data were acquired from USCB, PASDA, PAHEALTH, PADCNR, PFBC, and NCDC in 67 Pennsylvania counties for analysis and application. The results revealed that elderly migration can be explained not only by areal characteristics but also by spatial interaction considering the population, distances, and amenities of surrounding areas.

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 trend of human death ratio were investigated. As a result statistical analysis ratio of population over 85 years 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 ArcView^(TM) with the suggested index shows the time dependent variances of degree of immorality and spatial relationship between degree of immorality and human migration.

According to the growing concerns of the public with efficiency and effects of regional policies, their assessment works have become an important issue. Up to now, several studies have been carried out on economic effects of policies using conventional cost/benefit analysis, while there have been few studies on assessment of amenity oriented policies. From the above consideration, this study tried to develop An Annual Expenditure Assessment Model (AEAM) for amenity-oriented policy-making in rural area. As a pre-work for model development, the hierarchical indices system for rural development and the classification system of expenditure were designed. Being based on high significant relationship between rural amenities and local government expenditure, a linear optimization model for maximization of regional amenity was constructed. Through a case study of Sunchang-gun, Chonbuk-province, the model applicability was ascertained.

The purpose of this study is to verify the effect of urban agricultural practice on the factors of adolescent problem behavior. The main findings of this study are as follows. First, as a result of measuring quantitative research, urban agricultural practice improves 16.7% of self-worth, reduces 28.1% of depression, and improves 19.4% of sociality, the factors of adolescent problem behavior, and statistical significance is confirmed in all lower measures. Second, as a result of measuring qualitative research, there are overwhelmingly many cases that most items change positively or are maintained in sentence completion test. Third, a positive change of mind in adolescent communication, cognitive and problem-solving abilities, and participation is confirmed through observation of program participation behavior. It is significant for this study to confirm that urban agricultural experiential activity has a positive impact on the factors of adolescent problem behavior, and to verify educational effects and social values of urban agricultural practice including the necessity of development and operation of urban agricultural program to solve youth problems.

이 연구에서는 기후변화와 기술개발에 의해 생산량 변동이 큰 일년생 밭작물을 대상으로 기후변화 취약성 지표종을 선정하고자 하였다. 이를 위해 전남 지역의 각 시·군 단위 기후자료와 밭작물 생산 통계자료와의 상관분석을 통해 지역별 지표종을 선정하였다. 연구결과, 기후자료와 단위면적당 밭작물 생산량은 일정한 상관성을 가지며, 특히 연간 일조시간은 높은 상관성을 가지고 있어서 지표항목으로 설정하였다. 각 시·군별 지표종을 종합하여 보면, 고흥군은 콩, 곡성군은 파, 구례군은 고추, 나주시는 감자, 목포시는 오이, 무안군은 참외, 신안군은 파, 영암군은 감자, 완도군은 당근, 장성군은 시금치, 진도군은 호박, 화순군은 배추 등이 선정되었다. 본연구에서는 일조시간과 농작물의 단위면적당 생산량 간의 일정한 상관관계가 존재함을 확인할 수 있었으며, 기술발전 등 단위면적당 생산량 변화 영향을 미치는 기후 외적인 부분을 제외시킬 수 있다면 기후변화에 의한 지역의 밭작물 변화를 추정할 수 있을 것으로 기대된다. In this research, we try to develop an upland indicator plant selection model for vulnerability assessment of climate change. Climate and upland agricultural production data of Jeollanamdo were collected and statistically analyzed for finding the relation. We induced vulnerability from the sensitivity of agricultural production per unit area for excluding social and economic factors in agriculture. The duration of sunshine per year was selected as the representative of climate data because it has discrimination in climate data and relative to total upland agricultural production. Results show that upland indicator plants of climate change are bean in Goheung-gun, green onion in Gokseong-gun, pepper in Gurye-gun, potato in Naju-si, cucumber in Mokpo-si, melon in Muan-gun, allium fistulosum in Sinan-gun, potato in Yeongam-gun, carrot in Wando-gun, spinach in Jangseong-gun, pumpkin in Jindo-gun, and cabbage in Hwasun-gun. We verified that agricultural production per unit area of some upland crops in each region relate with climate change. If there are researches about change of agricultural production per unit area by technical development in each crop, we can estimate the effect of climate change to agriculture by region.

In the evaluation of rural amenities, its properties are related with social, cultural, and environmental elements. In this study, Information Measure Model (IMM) and Cultural Property Priority Assessment Model (CPPAM) were developed adapting information measure model with text based surveying data. To apply developed model not only general properties but also specific surveyed data, Specific Information Gathering and Utilizing System (SIGUS) was constructed using the data in Dusan World encyclopedia. IMM shows priorities of cultural property by information in national-designated cultural properties. And CPPAM applied in surveying data in 2004 by Rural Resources Development Institute.

Methodologies of the finite element and boundary element are combined to achieve an efficient and accurate analysis model of frame structure containing shear wall. This model analyzes the frame by employing the finite element method and the shear wall by boundary element method. This study is applicable to a specific situation, where the boundary element is surrounded by finite elements. By employing FE dominant method in which boundary stiffness matrix is transformed into finite element stiffness matrix, boundary element and finite element method are combined to analyze frame structure with walls.
