Enterprises or public organizations have invested in development of their information systems and operated them repeatedly. Since these information systems projects have unique characteristics such as technology sensitiveness, network effectiveness, embeddedness, and externality, these investment projects have been not taken care of in the field of administration and evaluation. And then, it is difficult to manage and monitor them. In this research, we propose a evaluation life cycle management model on the basis of result to evaluate information systems. This life cycle model with ten stages would furnish a guide to introduction of total evaluation systems.

Korean construction firms have been continuing investment of IT for last ten years. However, manager did not support a decision-making of IT because there is no evaluation and feedback system of IT investment. This study is a preceding research of making IT evaluation model as a part of MOCT(the Ministry of Construction and Transportation)'s construction CALS/EC policy and makes a basic frame through a trend and state of IT survey. As a result of survey, To encourage them, IT development to be balanced in each members for successful stabilization of CALS/EC as well as IT evaluation will be conducted in accordance with one's environment, such as a role and level of companies.

This research is aiming to specify the requirement of the investment such as intial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can be defer each other in their implementations. Second, though the remodeling of exist building to promote the functions has been applied, no suitable assessment tool has bee developed for deciding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific date base should be established to apply the suggested economic acessments in business enough ti forecast the future circumstances. More researches should be promoted on the area continuously as well as the integrated economic evaluation of remodeling on existing building.

This study aims to analyze the relationship between transport infrastructure investment and rural development in Korea in a more systematic and empirical way. To do so, we formulate research framework to examine the multi-faceted relationship through extensive literature review and carry out a descriptive study on the spatial patterns of road investment and rural development in Korea. Finally, using the structural equation model, this study carries out the exploratory empirical analysis on the direct and indirect relationship between transport infrastructure investment and rural development. The study finds that the transport infrastructure investment in rural Korea impacts clearly on both the population base promotion and production and income growth through better accessibility. In addition, the investment has an indirect effects on the production and income growth through its influence on the population base promotion. This implies that the transport infrastructure investment in rural Korea so far exerts both long-term and short-term influences on rural development through various channels of impacts.

Under traditional analysis of the capital budgeting, NPV, it is assumed that management cannot react to deviation from the expected scenario of cash flow at the time of evaluation. In practice, however, it is less likely that the expected scenario will come true when new information arrives and uncertainty is resolved. Uncertainty and risk can be influenced through 'managerial flexibility', which becomes a central instrument for value creation. Real option framework including option to defer, option for staged investment, option to alter, option to abandon, option to switch, etc. takes this managerial flexibility into account. Therefore, it is more appropriate to use real option method to evaluate the project than the traditional DCF(discounted cash flow) tool if the firm has high volatility of the expected returns.

In spite of IT performance can be achieved through the interaction of IT and organization, many previous study has been treated the introduction of the information system itself as a final outcome. But if it doesn't clear about understanding on IT performance, performance management is difficult and also it is impossible to produce the intended outcomes. This study investigates the improvement of the business performance of SMEs through IT investment, whether the investment process on business performance. Analytical methods that were used in previous studies were maintained and new model IO(Information Orientation) analysis was applied. Therefore, this study is meaningful to establish a new methodology, that is not attempted until now, for evaluating the performance of IT investment, and analysis relationship between IT investment and business performance.

This paper suggests a model for the economic evaluation and the selection of alternatives using teletraffic. Economic evaluation is analyzed by the comparison of revenue loss which happens without trunk extension and additional revenue which results from trunk extension. Simulation technique is used as a methodology to apply economic evaluation to telephone system. The study results will provide a support in a optimal decision about investment strategies.

Supply Chain Management(SCM) system is a critical investment that can affect future competitiveness and performance of a company. Selection of a right SCM system is one of the critical issues. This paper provides the characteristic factors of SCM system selection and the SCM system evaluation and selection model based on Analytic Hierarchy Process(AHP). The proposed model can systematically construct the objectives of SCM system selection to support the business goals. A empirical example demonstrates the feasibility of the proposed model and the model can help a company to make better decision-making in selecting SCM system.

Financial IT evaluation methods have been unable to satisfy firms' requirements. There has been a growing demand for more comprehensively and non-financially measuring the IT performance. We developed a process-based approach in evaluating impacts of IT on primary activities. In this research we proposed a model that uses the corporate objective of IT and strategic fitt as the core independent variables in measuring the IT effect. Based on the data collected from the management variables of the 125 companies located in Korea, the companies were classified into the 4 different groups according to their corporate objective for IT: un-oriented, operations oriented, market oriented and dual oriented. Through the empirical analysis, we were able to demonstrate that the management of the companies showing a higher orientation level perceives a better IT investment performance, and this shows that the corporate objective for IT serves as a useful index for measuring the IT investment effect. In this research, it was also demonstrated that the strategic alignment has a positive influence on perceiving the IT investment effect.

The Battery Energy Storage System(BESS) can help the load factor improved by discharging the battery energy when the load is peak in the daytime. BESS has the advantages such as spinning reserve, control of voltage and frequency, deferment of investment for generation and transmission capacity construction, and reliability improvement of utility power service. To develop BESS and to apply it to Korea's power system, economic evaluation must be preceded. In this paper, we analyzed the investment costs, by modifying and complementing the Sysplan Model, through the economic assessment.
