Midtown redevelopment project is intended for restoration of city's declining function and promoting the utilization of land, but several factors such as participants of different nature in the project, different expectation level from them, high land value accompanied by geographical location as a city and the demand for high density development, nature of business that requires long duration to complete and vast amount of fund contribute to complication of feasibility study. Due to these characteristics of midtown redevelopment project, consideration of various factors involved with it and reliable analysis are required but suggested complication of feasibility study is causing halt in project, preventing from launching it and delaying it. So, this study was undertaken to be a help to feasibility study of midtown redevelopment project by suggesting main elements that need to be dealt with analysing questionnaire survey result attained from related expert in this area and arranging total 45 factors essential to feasibility study for midtown redevelopment project that can be classified into 5 main category such as economic/financial factors, legal/institutional factors, market related factors, technical factors and conflict related factors through documental investigation, case study and interview with specialist concerned.

국가 R&D 사업에 대한 예비타당성조사 시 R&D 중복성에 대한 검토는 중복된 투자를 방지하여 재정 투자의 효율성을 높이는데 중요하다. 본 연구에서는 예비타당성조사 담당자들을 대상으로 중복성 검토에 대한 중요요인, 개선사항, 판단기준, 판단주체에 대한 설문조사 분석을 진행하였고, 외부 전문가 그룹의 인식차이와 비교하였다. 설문조사 결과에 대한 통계 분석을 통해 중복성 검토에서 가장 중요한 요인은 '중복성 판단기준, 시스템의 데이터베이스 및 검색 알고리즘'으로 확인되었고, 3가지 요인에 대한 개선이 중복성 검토를 개선하는데 가장 중요함을 확인하였다. 또한 다중회귀분석을 통해 주요 요인들이 중복성 검토결과의 정확성에 미치는 영향성을 분석하여 요인들의 유의성에 대해 확인하였다. 본 연구를 통해 예비타당성 조사 시 R&D 중복성에 대한 검토가 향후 어떤 방향으로 개선되어야하는지에 대해 시사점이 제시된다.

In the stage of feasibility study of urban rehabilitation projects, the precise forecast of physical and environmental changes has great influence on the further transaction of the projects. However, various important decision makings are made by the experience and intuition of the person-in-charge in practice without the process and method for systematic and quantitative analysis. In spite of various qualitative influent factors on the projects, the feasibility studies are made by the result of economic analysis only, which often lead the projects to the crucial deficit. The main reasons of such a mal-functional transaction are due to the absence of the reasonal procedure of feasibility study and decision making reflecting the characteristics of urban rehabilitation projects. The objective of this paper is to propose feasibility study processes and decision making methods in relation to various influent factors on urban rehabilitation projects in the initial stage. The goal and process of every analysis stage and the pertinent factors and decision makings are analyzed and proposed through the survey of current research, a case study, interview with the professionals. The processes and methods are well applied to improve current problems of feasibility study of urban rehabilitation projects. In addition, the establishment of the analysis goal at three principal stage and a series of reasonable decision makings with pertinent factors to each stage will lead the project to more successful result than ever.

Risk analysis model is systematic and structural process that considers internal security problems and threat factors of the information systems to find optimal level of security control. But, the risk analysis model is just only defined conceptually and there are not so many empirical studies. This research used structural equation modeling(SEM) research methodology with rigorously validated research instrument. Based on results of this study, risk analysis methodology was proved to be practically useful in e-commerce environment. Factors like threat and control were significantly related to risk. In conclusion, the results of this study can be applied to general situation or environment of information security for analyzing and managing the risk and providing new approach to comprehend concept of risk in e-commerce environment.

본 연구는 정보보안 수준을 효과적이고 효율적으로 측정할 수 있는 간편한 지표를 개발하는 목적으로 수행되었다. 기존 관련연구 및 지표를 분석하여 문제점을 도출하고 개선 방향을 설정한 후, 관련전문가들에게 예비조사를 실시하여 후보지표 항목을 선정하였다. 선정된 후보지표 항목에 대한 타당성 검증을 위해 보안 전문가 집단에게 설문조사를 실시하였다. 요소로서의 타당성, 상대적 중요성, 항목 결여시 보안사고 발생확률, 사고의 심각성 등 4가지 기준에 의한 설문조사 결과를 분석하여 각 후보 지표 항목에 대한 요소로서의 타당성을 도출하였다. 대부분의 후보 항목이 바람직한 항목인 것으로 나타났다. 향후 요인 분석과 상관 분석 등을 추가로 수행하고, 보안 수준을 계량화하는 연구로 발전시킬 필요가 있다.

본 연구는 한국의 벤처캐피탈회사들이 투자안이 투자여부를 판단하는데 사용하는 평가모형이 실제의 성과와 비교하여 타당성을 갖는가를 분석하였다. 이를 위해 본 연구는 다음의 두가지 투자모형을 도출하여 그 내용을 비교하였다. 실제심사모형(Current Evaluation Model)은 심사과정을 거친 168개 투자안을 coxorehlse 그룹과 기각된 그룹으로 분류하여 이에 대한 판별분석을 통해 투자여부에 영향을 미친 평가요인의 우선순위를 규명하여 도출하였다. 한편, 성과모형(Performance-based model)은 앞 모형에서 채택된 투자안을 다시 성공과 실패의 두 그룹으로 분류하고 이를 종속변수로 한 판별분석을 통해 성과에 대한 평가요인의 영향도를 파악하여 개발하였다. 이 두 모형을 비교함으로써 본 연구는 우리나라 벤쳐캐피탈이 적용하는 투자평가시스템의 문제점을 파악하고 그 원인을 고찰하였다. 본 연구는 미국 등 선진국과 달리 다양한 투자환경에서 나타날 수 있는 투자평가모형의 타당성을 검증할 수 있는 접근방법을 제시했다는 점에 큰 의의가 있다. 이러한 접근을 통해 현 평가 모형의 문제점을 파악하고 개선방법을 제시할 수 있을 것이다.

Self-Compassion(SCS) Scale is developed by Neff(2003a) and translated by Kim, Lee, Cho, Chae, Lee(2008). But, there is the limitation with validation SCS and Korean version Self-Compassion(K-SCS) performed in college students and the incoherence for the results of the scale's factor analysis in other countries. Therefore, this study examined the validity of factor structure in SCS based on data in 435 adult aged from 18 to 79. For this, we conducted exploratory factor analysis(EFA) and confirmatory factor analysis(CFA), and we examined the each adequacy of two-factor, tree-factor and six-factor model. The result of EFA supported six-factor and the result of CFA was the six factor model best as well.

The startingpoint of successful buildingproduction process is the feasibility study of the project. If the feasibility study is poor which is affected in direct production processes such as designing and engineering, it incurs a great unrecoverable loss to the company. The governmentinstitutionalized the feasibility study for projects that budgets over 50billion won in an effort to ensure competitiveness of the construction industry after IMF; however, the system and effort to created systematic studies or guidance preparation for private construction development projects are lacking in great deal. Therefore, the objective of this study is to establish the analysis factors of feasibility study and evaluation standard by systematic analysis in consideration of the changes of various variables and mutual relationships using system dynamics technique for office buildings among commercial buildings.

The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.
