The interest in economics and efficiency of IT investment is growing as the amount of overall governmental IT investment steadily increase. Accordingly, there is a strong need to determine whether the expenditure incurs effectively for IT investment and to accurately analyze the economics of IT investment, In this perspective, this study discusses the prior researches on concepts regarding the analysis of IT investment management framework as proposed from academic and professional perspectives in advanced countries' government sectors. Thereafter, an adoption of IT investment management (ITIM) framework has been considered so as to enhance the performance of ICT initiative projects in the public sector. In the suggested IT investment management framework, we suggest economics and efficiency of public IT investment should be improved by integrating ICT project selection and control as well as evaluation stage into single governance framework.

정부는 최근까지 창업 촉진 및 신규 일자리 창출 도모를 목적으로 비 수도권 제조 창업기업에 대해 창업투자 보조금을 지원해 왔다. 정부의 이러한 보조금 지급 결과, 4년간 총 1조 5천 4백 60억원 정도의 매출 증대 효과와 비정규직 포함 총 3,825명의 고용 효과가 있는 것으로 분석되었다. 본 논문에서는 창업투자 보조금에 대한 전반적 성과와 더불어 개선되어야 할 정책적 방향성에 대한 제언을 한다.

The use of school should not be limited to student education any longer but be extended for attaining social benefits. For this reason, school should play central roles not only in education but also in childcare, welfare, culture, physical education, etc. In order for school to accommodate various new functions, it is essential to promote the mixed-uses of school facilities, and this process requires the involvement of private capitals for early achievement of social benefits from school facilities. Thus, this study purposed to examine the necessity of the multiple uses of school facilities through the investment of private capitals, to diagnose the adequacy of build-transfer-lease (BTL) applied currently to the multiple uses of school facilities, and to find obstacles to the activation of private sector investment and suggest solutions for the obstacles. In particular, this study aimed at proposing plans to enhance the efficiency of private sector investment and activate private sector investment projects by suggesting how to promote the multiple uses of school facilities in consideration of profitability for private investors.

We focus on the issues of the non-linear return/risk relationship of IT investment and the balance between return and risk of IT portfolio. We develop an IT project selection model by integrating DEA models with Markowitz portfolio selection theory. The project data collected from a Fortune 100 company are used to illustrate the implementation of the model. In addition, computational experiments are conducted to demonstrate the validity of the proposed model.

It was on the rise importantly to provide the efficient management process of the organization for dealing with the change about information and business management quickly and consistently. It was suggested with the architectural model on information technology to provide it in theoretically. The Federal Government and budget organization of the USA used it on actual business and the terms of EA (Enterprise Architecture) and are raising the efficiency of management. NCA (National Computerization Agency) of Korea published the book - "The Research about establishing ITA (Information Technology Architecture) and appling the standards". After being applied the model on MOGAHA (Ministry of Government Administration and Home Affairs) and MIC(Minisstry of Information and Communication), the concrete case was made. MOMAF (Ministry of Maritime Affairs and Fisheries) drove the leading model. The report ascertained the basic contents of ITA and researched the case of USA, MOGAHA, MIC, and tried to analyze the contents of appling maritime and fisheries area. The report contained the definition of purpose through analyzing environment and establishing the vision and the principles based on them. The report also contained the contents of architecture based on the standard of NCA - "The Government Standard Meta Model version 2.0" - and researched the MOMAF's Reference model using Government Reference model. The report established the investment architecture and the process of information technology asset management. It ascertained the characteristic of maritime & fisheries area and the subject of developing the MOMAF's ITA sustainably.

Korea has been ranked at the top consecutively in UN e-Government Survey. This fact reflects consistent efforts by public institutes in Korea. However, there were some duplicate efforts and inefficiency in the investment into IS(information systems). In other words, management and decision making on e-government have yet to improved. Accordingly, governmental institutes have long been promoting policies for EA in order to carry out and manage effectively IT projects including the e-Government projects. EA is being regarded as a means to facilitate IT Governance for systematic management of IT projects, A major objective is to firmly establish the decision making process for IS investment through EA, since the each institute is a large organization with so complicated and specialized demand for IS. As a result, systematic decision making is becoming quite difficult. Thus, this study attempts to identify different types of IT investment decision making and to figure out the relationship between the decision types and the organizational performance of public institutes where EA was implemented.

Early decision support systems (DSS) were the "passive" decision support systems in the sense that the systems only able to do what the users explicitly direct them to do. But some researchers such as Raghav Rao et al. [51 showed architectures to suggest general idea of the innovative DSS systems which offer active form of decision support, say, "active Intelligent Decision Support Systems(active IDSS)". The system can perform not only what the users want to do but some voluntary (or involuntary) intelligent works. This paper presents the issues in the design of the active IDSS in the domain of investment evaluation, a domain area where few researchers have suggested frameworks or architectures to discriminate good investment from bad one. We propose a new paradigm, by utilizing historical investment results using neural network and Multivariate Discriminant Analysis(MDA), to identify goodness of investment. A new active IDSS architecture which consists of neural network, expert system and three components of the traditional passive DSS is suggested with some scenario based results.nario based results.

우리나라는 정보화 부분에 '04년부터 '13년 까지 지난 10년간 연 평균 약 3조 2천억 원을 투자를 해 오고 있다. 정보화투자 형태에 있어서는 정부정책 등에 따라 예산 증가와 감소의 주기적 반복현상을 보이고 있다. 특히, 운영 및 유지보수 등의 고정비용은 새로운 정보화 수요에 대한 여력을 감소시키는 현상을 초래하고 있다. 이 같은 상황임에도 불구하고 지속가능한 정보화 추진체계 구축을 위한 중 장기적 정보화 투자방향 수립에 필요한 문제 제기는 부족한 실정이다. 본 연구의 목적은 공공부문에서 신규 정보화사업 투자의사결정 시 기관에서 요구한 정보화 수요를 맞추기 위해 필요한 사전적 요건과 준비사항을 정리하기 위한 기초연구이다. 이를 위해 수요예측 기반으로 정보화 투자방향을 잡기 위한 개념들을 개관하였다. 그리고 국외 및 국내의 관련사례들을 목적과 기준, 방법과 정보, 지원시스템 관점으로 살펴보고 각각의 사례별 시사점을 도출한다. 이를 통해 정보화투자의사 결정 대상이 되는 사업들을 수요예측 기반으로 하여 투자방향 정립 방안을 제시해 보았다. 연구결과는 공공 정보화예산을 보다 효율적으로 관리할 수 있는 정책자료 중의 하나로써 활용되었으면 한다.

As the zero interest rate era was over with the end of quantitative easing, the economy of several global markets observed the fluctuations of the base interest rate. Interest rate, which is the change of money value with respect to time, is negatively correlated with construction investment. Considering the characteristics of interest rates and construction investment as economic variables, the necessity of cross-border analysis between base interest rate and construction investment was suggested in this paper. Cross-correlation analysis between base interest rates and construction investment crossing the border was performed. The effective correlations were confirmed with values varying by countries. Similar characteristics were also observed among countries with similar economy, which were then divided into three groups. Additionally, identifying the base interest rate that affects the construction investment of a particular country was made possible by reflecting a self-cycle of base interest rates. Lastly, from the result of examining the influence of each rise and fall of the interest rate, it was verified that the difference was more than twice as large in some countries. These results are expected to contribute to construction-related policy makers or investors to make decisions in response to the economic status of the construction market.
