The Information System(IS) planning for construction project management must be performed through decomposing the construction management business process upon considering the information technology in a construction company. Following this background, this paper proposes a model for evaluating the expected value of IS planning for construction project management. The model is made to analyze the effectiveness and to evaluate the opportunity of IS planning for task and information, then finally to quantify the value. Lastly, this model can be used to plan IS for construction project management.

Option pricing model in finance has been applied to price non-financial options, called real options. The real option valuation method is ideally suited to irreversible decision making under uncertainty, including the need to determine the optimal time to act and even change between alternative courses of action as information is collected. Therefore, the real option valuation method is expected to provide a superior and less subjective approach to determining optimal strategies for water resources supply projects, which have been reported to have huge risks due to uncertainties, and investors and policy makers need to build an optimal strategy - when and if to invest - with uncertainties and managerial flexibilities considered.

This research proposes a new approach to measure corporate contributions to sustainability called Sustainable Value. With some global corporations which recognize the seriousness of environmental crisis and their social responsibility, enterprises are positively accepting the sustainable management. Also, publication of the sustainability report is proliferating which is showing the enterprise's strategy, activity, result and influence in environmental, economic, social cases to the stakeholder. However, to settle and proliferate this current, it rests with how to evaluate enterprises sustainability in reasonable and reliable figure. In this context, what introduced and taking effects are sustainability report evaluation and awarding system. But the quality of sun stainability report and its content's depth and the evaluation of enterprise's sustainability itself should be distinguished. Because the enterprise which published excellent graded sustainability report is not always the enterprise that is sustainable. Then, how could we prove the result of enterprise's sustainable management based on sustainability report? This paper is to find the answer and to utilize it based on sustainability report, particularly sustainable value model as the central figure.

The purpose of this study is developing a information support system for R&D decision making to maximize economic results of the R&D. This system is composed of studying the model of work flow for R&D decision making, analyzing a technology information, connecting with the databases from KISTI and others, and valuing R&D technology on line. Especially in the case of technology valuation, this system is combined with the valuation model which supports knowledge information for helping more objective estimation.

For efficient maintenance management of bridges, an establishment of asset management system is necessary which helps prediction of maintenance cost and strategic allocation of budget in consideration of top priority. The main purpose of this study is to suggest asset valuation method, which is practical in conformity with domestic situations, through researches on asset valuation method of bridges. This study has researched asset valuation method of bridge, which is appropriate for domestic situations by finding out advantages and disadvantages through investigating domestic and foreign application examples of asset valuation method for bridge facilities. In this study, asset valuation method by historical cost and replacement cost were suggested and a valuation model for bridges was established. In addition, two suggested valuation methods were applied to actual bridges which is used in Korea. As the result, it was analyzed that bridge asset valuation method in consideration of historical cost is desirable for the accounting purpose. And, it was analyzed that valuation method utilizing depreciated replacement cost(DRC), which could consider various factors, is desirable for the maintenance decision supporting purpose.

Real estate development requires significant amount of capital investment. The project duration has been increased according to its enlarged size. For this reason, cost overrun and time delay are important risk factors that should be managed properly. As a method to hedge the risk, varoius real option methods have been presented. However, conventional project value assesment methods such as NPV(Net Present Value) have weakness to support decision making by reflecting dynamic situations in terms of variation of cost and time. Furthermore, the decision making process is serious of actions rather than discrete event. The purpose of this paper is to present a multiple real option valuation method to overcome the deterministic aspect of real option presented in previous research and practice. The method is developed as following: firstly, to select the model that can be applied in the real estate development project through a survey from previous literature on real options analysis; secondly, to apply data from office development case in order to verify the model by applying conventional real option and multiple real option valuation. According to analysis result, multiple real option provides enhanced values comparing to NPV and single real option.

As transaction and investment using technology are vitalized, the need for objective standards for the technology is increasing. Current technology value evaluation system is limited lacking reliability and objectivity. Besides the traditional evaluation methodology which are market approach, income approach and cost approach other diverse evaluation methodology such as real option method and royalty calculation method are being studied; however currently there are no dominant evaluation methodology in the market. Same value evaluation system cannot be applied between similar technologies because value of technology is relatively decided based on the target. Approaching through collective intelligence and crowd sourcing, in meaning of majority participant's decision can make objective and better result than handful of experts, suggest alternative to problems of such matter above. By grafting the four types of crowd sourcing model which are Wisdom, Voting, Funding and Creation, this paper will discuss the ways to enhance the objectivity of technology evaluation through direct evaluation utilizing expert group and the public's indirect evaluation.

기술에 대한 선점이 기업 경쟁의 핵심이 되는 현 시점에서 관심 있는 기술의 경제성, 발전 가능성과 같은 기술 가치를 판단하는 것은 매우 중요하다. 따라서 본 연구에서는 현 시점에서 어떤 기술에 진입하는 것이 옳은지에 대한 의사 결정을 지원할 수 있는 모델을 제안하고자 한다. 기술의 진입 여부를 결정하는 것은 현재 시점에서의 기술의 가치를 판단하는 것과 일맥상통하므로, 가장 대표적인 기술 가치 평가 소프트웨어인 미국 NTTC의 TOP INDEX에서 사용한 평가 항목을 기준으로 하여 기술 진입 가능 지수를 개발하였고, 계산된 지수 값에 의해 기술의 진입 여부를 판단하게 된다. 추후 성능 테스트를 통하여 개선 방향을 도출하고 지속적으로 보완할 예정이다.

Since the late 20th century, there has been much effort to improve the market value of media contents which are commercialized in a digital format, by fusing digital data of video, audio, numerals, characters with IT technology together. Then by what criteria and methodologies could the market value for the drama "Sons of the Sun" or the animated film 'Frozen', often referred to in the meida, be estimated? In the circumstances there has been little or no research on the valuation framework of media contents and the status of their valuation system development to date, we propose a practical valuation models for various purposes such as contents trading, review of investment adequacy, etc., by formalizing and presenting a contents valuation framework for the four types of media of movies, online games, and broadcasting commercials, and animations. Therefore, we develope computational methods of cash flows which includes production cost by media content types, provide reference databases associated with key variables of valuation (economic life cycle, discount rates, contents contribution and royalty rates), and finally propose the valuation framework of media contents based on both income approach and relief-from-royalty method which has been applied to valuation of intangible assets so far.
