Providing the reasonable construction cost at the initial stage of the rural development project, is a kety factor of the each step of project , such as propriety analysis , cost planning , design, and planning the progress of work. The explainable construction cost can be estimated at the early stage using the actual cost data by statistical analysis. In this study, the influence factors are extracted by factor analysis with the actual cost data of rural development project, object cost model is developed by multiple regression analysis, and verify the developed cost model by Monte-Carlo simulation .

This paper presents a substation expansion planning method with quantitative analysis using ANP. To calculate the reliability factor and economy factor of the system, reliability indices and total construction cost is used. With these factors, new ANP model which select the best plan either economy or reliability among various alternatives is developed. This model can assist the decision making for the system planner. The usefulness of the method is verified by applying it to the large-scaled distribution system.

Over the past two decades, forecasting has gained widespread acceptance as an integral part of business planning and decision making. Accurate forecasting is a prerequisite to successful planning. Accordingly, recent advances in forecasting techniques are of exceptional value to corporate planners. But most of forecasting mothods are reveal its limit and problem for precision and reliability duing to each relationship for raw data and possibility of explanation for each variable. Therefore, to construct the Integrated Forecasting Model(IFM) for Information Factor Analysis, it shoud be considered that whether law data has time lag and variables are explained. For this. following several method can be used : Least Square Method, Markov Process, Fibonacci series, Auto-Correlation, Cross-Correlation, Serial Correlation and Random Walk Theory. Thus, the unified property of these several functions scales the safety and growth of the system which may be varied time-to-time.

This study deals zoning and building codes that act on the physical planning and design of university campus in Korea. Campus facility related laws were analyzed in relation to various factor found out through the survey on the existing campuses in rural or urban area. The study shows that the gaps between the standards required by the law and the state of facilitation in many universities could be filled by applying varied norms in accordance with the locational characteristics of each university.

This study began to learn wether or not satisfaction factor of rural tourism is effective to visit for the ordinary foreign people. Research method was parallel-site investigation literature, questionnaire. The analytical data of the study, literature 40 reviews, questionnaire 179 survey in 200 of the subject was using. Measurement and scale was set factors of satisfaction with 'Transportation Infrastructure', 'Festival Experience Program', 'Place', 'Room and Food', 'Local People', and 'Buying the Local Product' through the previous studies and preliminary survey. In the statistical analysis method, frequency analysis, crosstabs, multiple regression analysis and a structural equation model analysis was performed, using SPSS and AMOS program. The Structural analysis results showed 'Place' and 'Local People' have an positive effect on the 'Overall Satisfaction'. Satisfaction of the 'Festival ExperienceProgram', had a major impact also 'Intention of Revisit'. Finally for rural tourism fascination, the contents such as the distinctive local attraction, human resources, information transmission and convenient use is more important than the format and scale.

The purpose of this study is to analyze the characteristics of the 11 southeastern states in the United States by using regional characteristics variables and to classify the regions. First, 19 variables from four categories of population, society, industry-economy and urban service were selected and factor analysis were conducted, and the result showed five major factors of population, economic condition, job and commuting. Based on the following factor scores, a cluster analysis was conducted, and eight types of big city, medium-sized city, bed town, small town, urban hinterland, retirement town, and rural village were derived. These types of spatial distribution characteristics showed big cities were by different types of regions and they formed metropolitan areas. Each types of classified regions were located along the road network with hierarchy. The study focused on cases in the southeastern regions of the United States and can be used as a comparison with Korean cases. If the same research method is applied to Korea in the future, or if the time series of changes is tracked by analyzing different time points, it will greatly help identify the characteristics of urban and rural mixed areas.

본 연구에서는 원격탐사와 GIS 기술을 이용하여 지형특성을 분석하고 효과적인 토양보존계획 및 관리를 위해 검토되어야 할 토사유실 원인지역을 선정하기 위한 전략적 접근방법을 제시하였다. 이를 위해 지형학적으로 인접되어 있지만 저수지의 탁도에는 매우 큰 차이를 보이고 있는 안동과 임하호 유역을 선정하였다. 각 유역에 대한 효과적인 토양보존계획 및 관리를 위해서는 강우발생에 따른 토사유실의 전반적인 거동을 파악하는 것이 중요하다. 또한 토양보존 프로그램의 효용성을 증가시키기 위해서는 각 유역을 구성하고 있는 소유역별 토사유실 잠재성을 심도 있게 분석해야 한다. 특히 본 연구에서는 안동호와 임하호 유역을 상류, 중류, 하류로 구분하여 토양침식인자, 지형인자, 식생피복인자 그리고 토사유실량의 거동을 분석하였다. 여기서 제시된 접근방법은 토양보존계획을 위해 검토되고 관리되어야 할 우선지역 선정을 위한 가이드라인을 제공 할 것이다.

본 연구는 폐암 환자의 정위방사선치료 시 환자의 호흡인자를 적용한 치료계획을 설정하여 그 유용성을 평가하고자 하였다. 폐암 환자 10명을 대상으로 4차원 컴퓨터단층촬영을 시행하고, 환자의 호흡 인자를 적용한 치료계획과 기존의 치료계획과 비교 평가하였다. 실험은 폐의 용적변화, 폐의 방사선 흡수선량 변화, 폐암 주위의 중요 장기의 흡수선량 등을 분석하였다. 본 연구에서 호흡인자를 적용한 방사선 치료계획 시 기존의 방법과 비교하여 폐의 용적변화, 폐의 방사선 흡수선량 변화, 폐암 주위의 중요 장기의 흡수선량의 차이를 확인할 수 있었다. 결론적으로 폐암 환자의 정위체부방사선치료를 위하여 호흡인자를 적용한 방사선 치료계획 방법은 유용할 것으로 사료된다.

The purpose of this study is to examine the factors affecting on CRPI (capability of retirement planning and implementing) and to identify the critical point of financial factors to increase CRPI. 908 Korean individuals' data were used for descriptive statistics, t-test, F-test, and Generalized Linear Mixed Model Analysis. As a result, CRPI was influenced by attitude toward retirement planning, gender, income, and propensity to save. Some mid-group did not make a significant difference in CRPI compared to the lower-group. Men were more capable at CRPI than women in terms of sense of independence and getting a consulting service. Most consumers appear to have difficulty in calculating their retirement fund. People who have income over 3,000,000 won have dramatically greater CRPI than people who have income under 3,000,000 won. And people who have saving ratio over 23% have significantly greater CRPI than people who have propensity to save under 23%. The monthly income 3,000,000 won and propensity to save 23% were considered as critical points related to CRPI.
