In this study, an evaluation system for a water resources technology research and development project, which is one of the 21C frontier R&D programs sponsored by Korea Ministry of Science and Technology, is proposed. The purpose of this paper is to contribute in the implementation of an efficient R&D policy scheme and in the successful commercialization and diffusion of water resources technologies through proper evaluation of water resources technology R&D projects. The evaluation system is consisted of two levels of evaluation categories and attributes to reflect qualitative evaluation as well as quantitative evaluation of the water resources technology development. The weights of 4 evaluation categories and 26 attributes are calculated by using Analytic Hierarchy Process(AHP). To demonstrate the evaluation system, a numerical example of water resources technology evaluation is presented.

As the need for quantitative qualities of IT investment performance heightens, numerous research organizations are developing various measurement methods for the quantitative evaluation and its currency value conversion. Corporations utilizing these methods to evaluate IT investment performance are gradually increasing. However, working-level staff in the corporations that have introduced the quantitative evaluation can not assure if the evaluation sufficiently reflects the actual effect provided by IT since the results arising from the conversion of currency value can't be visibly confirmed. This study tries to identify whether the quantitative evaluation of IT investment performance can be explained in terms of the level of consumer satisfaction proven by the qualitative evaluation by analyzing the level of consumer satisfaction and quantitative evaluation of a case company and identifying the correlation between them. As the result of the case study, the following points have been concluded. Firstly, the currency value of IT effect correlates with the level of consumer satisfaction. Secondly, in order to come up with a rational currency value of IT effect, developing an indicator as well as managing data on currency conversion that will enable the internal system's efficiency to become more quantitative is essential. Thirdly, IT ROI is not appropriate to compare the performance between systems and is utilized as a measurement standard for each system's performance and efficiency. Lastly, quantitative evaluation is still inadequate in the evaluation of the system's strategic side, and consumer satisfaction can be utilized as a supplementary method.

Technology valuation is necessary for determining the feasibility of technology commercialization. However, existing methods focus only on technology evaluation, with limitation in sufficiently reflecting buyer viewpoint. In addition, it causes a gap between estimated value and market value. Therefore, this research suggests a new technology valuation method which focuses on the perspectives of buyers. Technology factors, buyer factors and market factors are first determined and their relationships are analyzed. Second, based on the relationships, profit projections are calculated using the discount cash flow method. Finally, profit projections for each year are discounted. The proposed method was applied using the ubiquitous home network system and audio service and illumination control method and results compared with the value of a technology valuation guide distributed by the Ministry of Trade, Industry and Energy. The technology valuation approach used in this research is quantitative and systematic and can be used as a decision making support tool in technology transfer, reflecting various perspectives of stakeholders.

In the domestic data exchanging market, unreasonable pricing of purchase data is consistently mentioned as a major obstacle in data trading. This is a problem caused by the inability to properly evaluate the value of data products due to lack of product information and experience in using them. In order to activate trading, the data exchanges need to provide information that allows consumers to comprehensively judge the value of data products in addition to prices. The cost-based, income-based, and market-based methods, which are mainly applied to data valuation, are insufficient as data valuation methods to stimulate trading and distribution because only price information, a result of valuation from a supplier's point of view, can be shared with consumers. This study aims to develop a measurable valuation method that allows data trading stakeholders (exchanges, suppliers, and consumers) to judge and share the value of data products from a common perspective. To this end, we identified the value drivers of data products, which are considered important in overseas data exchanges and related research, and derived an evaluation method that can quantitatively measure each value driver. In addition, evaluation criteria in the form of a rating table were developed using data products for transactions, and a value evaluation index was developed through stratification analysis (AHP) to enable relative value comparison. As a result of applying the evaluation criteria to actual data products, it was found that the evaluation values were differentiated according to the characteristics of individual data products, so it could be used as a relative value comparison tool.

Traditionally, the feasibility of the private investment is determined by NPV(Net Presented Value) based on DCF(Discounted Cash Flow) and the volume of government's subsidiary without quantifying the effect of overturn share ratio and MRG(Minimum Revenue Guarantee), these variables which can seriously effect on the economic feasibility. One of the most important reasons why these variables are not underestimated is that the quantifying methods are insufficiently or so complicatedly studied to apply practically the real project. Therefore, this study suggests the modified binominal option model to estimate the overturn share ratio and MRG and estimates how much these variables impact the private investment. Also, these results are helpful to estimate how much the government's subsidiary can be reduced.

현재까지 주요 항만의 운항경로에 설치되는 항로표지의 선택과 배치는 전문가의 경험에 의지하여 결정하여 왔다. 이에 따라 기존 항로표지 설치에 대한 객관적인 근거와 타당성을 확보하기 어려웠다. 그러나 최근 빠른 연산 능력을 지닌 컴퓨터와 이를 이용한 시뮬레이터를 활용하여 보다 빠르고 정확한 프로그램을 운용할 수 있어 전문가의 경험에 의존하는 전통적 방법을 대체하고 있다. 이에 본 연구는 국제 규격과 경험식을 기준으로, 항로표지를 배치하여 산출되는 수치를 비교 분석하여 정량적인 평가를 통한 최적의 항로표지 배치를 도출하는데 그 목적을 가진다. 본 논문에서는 국내 특정 항만을 대상으로 적용한 시뮬레이션 결과를 통하여 항로표지 시뮬레이터의 추후 사용 가치와 발전방향에 대하여 논한다.

In spite of various approaching method to satisfy with the owner's requirements in schematic design phase, it is insufficient to evaluate intermediate process of design arithmetically with participating in design process. So the numerous changes of design after completion of design development cause a lot of loss to the design company. The designer arranges owner's requirements to prevent from this loss at the initial stage of schematic design phase systematically and lets owner and stakeholder to evaluate the value of schematic design to satisfy with owner's and stakeholder's requirements. If the evaluated value for schematic design is above a definite value index, the next design phase should be advanced. By this method, the design company can reduce the additional expenses remarkably by preventing with re-design which is occurred by not reflecting owner's intention or by changing owner's intention. Also the designer have the owner to evaluate the result of design and construction. The designer let the owner know whether the owner's requirement should well have been reflected on drawing or not. There is a strong point to be able to minimize the criticism which can be occurred after completion of construction by evaluating for owner's satisfactory degree and by having owner and designer confirm the result of design and construction arithmetically. This paper presents that the loss of design company can be minimized by going over at next step if the value is over a definite value index after evaluating value for each design from design process.

A number of BTL projects for educational facilities have been augmented because of the increase of newtown development and deflationary policy of class size for learning efficiency. As the operation and maintenance costs rapidly increase, the budget for operation and maintenance is expected to be short. Therefore the asset management maximizing asset value is required to clarify the budget plan and distribution and provide a qualitatively high service. The main objective of this research is to establish asset valuation process in educational facilities delivered by BTL project. In order to meet the research objective, the asset valuation process is established by literature reviews, expert advice, and lessons learned from the developed countries. The developed process includes depreciation by internal accounting law, the core element of valuation, and asset valuation process. The results of the research will be help to offer the qualitatively high service and explain the standard of budget plan. It will assist commencing the asset management system.

In many countries, governments invest a substantial amount of budget in open government data (OGD) for governmental performance and transparency. To understand the actual performance of such policies, the governments should measure the realized value. Many organizations and researchers have attempted to assess the value of OGD. However, they have neglected a perspective of consumers who benefit from OGD. Moreover, little research has quantified the economic value. This research examines extant methods of intangible asset valuation to quantify the economic value of OGD in a citizen perspective. In consideration of the extant research methods and the characteristics of OGD, the contingent valuation method is the most appropriate because it effectively reflects various users and their purpose of use. We then conduct a survey of citizens living in Seoul, Korea and assess the economic value of OGD provided by the Seoul government. Findings show that citizens' willingness to pay (WTP) differs across respondents' prior experience, tax resistance, perceived benefit and perceived reality of virtual scenario, but it does not differ across their demographics. WTP also significantly varies across the question formats. We discuss the reliability of the results and implications for future research.
