The present study was conducted to analyze the quality of the habitats of Abies koreana WILS. by using the InVEST model based on the analytic hierarchy process (AHP) technique and to evaluate the economic value by estimating the carbon fixation. Abies koreana WILS., an original biological species of South Korea, may be an essential element in establishing the national biological sovereignty in the future. The subjects of the present study were the national parks in Mt. Halla, Mt. Jiri, and Mt. Sobaek, which are the habitats of Abies koreana WILS. As suggested by previous studies as a limitation of the InVEST model, the utilization of the data from relevant international publications as the input data, due to the lack of the domestic input data, may decrease the accuracy of the modeling. Therefore, the AHP technique was applied for the input data. The modeling was performed with reference to the years of 1980, 1990, and 2000 for the scenario analysis. The result of the modeling showed that the habitat quality was changed most in the national park in Mt. Halla, as the habitat quality score was decreased from 0.96 in 1980 to 0.97 in 1990 and 0.94 in 2000. In the national part of Mt. Sobeak, the habitat quality was changed most in the sub-alpine zone, as the habitat quality score was decreased from 0.98 in 1980 and 0.98 in 1990 to 0.97 in 2000. The habitat quality was best conserved in the national part in Mt. Jiri, as the habitat quality score was 0.98 in 1980, 0.99 in 1990, and 0.99 in 2000. The estimated economic loss by the change of the habitat quality was 19,280,000 USD for Mt. Halla and 8,030,000 USD for Mt. Sobeak. In the present study, the habitat quality of the Abies koreana WILS, the original species of South Korea, was evaluated and the economic value of the ecological services provided by the habitats was estimated quantitatively. The result showed that the ecosystem service model may be used to qualitatively analyze the quality of a habitat located in a specific region and to estimate the economic value quantitatively. The objective evaluation of ecosystem services demonstrated in the present study may be applied to promote sustainable utilization of natural resources and conservation of the ecosystem by predicting the changes that may be caused by external factors including the development of preservation areas.

국내에서 천연 제올라이트는 부존자원으로서의 높은 잠재성에도 불구하고, 용도개발에 대한 연구개발이 부진하여 관련산업이 활성화되지 못하고 있는 실정이다. 환경개선용 기능성 소재로서의 천연 제올라이트의 응용이 앞으로 국내에서 천연 제올라이트의 부가가치 향상을 도모할 수 있는 효과적인 방안이 될 것으로 생각된다. 환경산업 분야에서는 천연 제올라이트가 합성 제올라이트와의 경쟁관계에서 유리한 위치를 점유할 수 있을 것으로 판단된다. 환경산업에서 천연 제올라이트의 새로운 수요처가 형성되면 기존의 저급한 용도보다 한 단계 향상된 부가가치의 창출이 가능할 것으로 여겨진다. 국내산 천연 제올라이트의 자원잠재성과 부가가치를 제고시키기 위해서 앞으로는 관련산업이 응용광물학적 지식기반 산업으로 전환되어야 한다. 또한 지금까지 국내에서 천연 제올라이트에 관례적으로 적용되어 왔던 화학조성 및 CEC 분석자료에 의거한 제올라이트의 품위 및 품질 평가 방식에서도 개선과 보완이 요구된다. 특히 X-선회절 정량분석, 전자현미경관찰, 선택적 이온교환 및 흡착특성과 관련된 실험 등을 통해서 천연 제올라이트의 품위와 품질이 보다 정밀하게 감정되고 평가되어야 할 것으로 여겨진다. 따라서 앞으로는 천연제올라이트의 부가가치 향상을 위한 연구개발과 산업응용은 반드시 제올라이트의 세공구조, 광물상, 광물 조성 및 특성에 대한 이해와 지식에 기반하여 이루어져야 할 것이다.

Measuring the intangible asset has been vigorously studied for its importance. Especially, the value of character in media industry is difficult to quantitatively evaluate in spite of the industry's rapid growth. Recently, the Social Network Analysis (i.e., SNA) has been actively applied to understand human usage patterns in a media field. By using SNA methodology, this study attempts to investigate how the character network characteristics of media works are linked to human search behaviors. Our analysis reveals the positive correlation and causality between character network centralities and character search data. This result implies that the character network can be used as a clue for the valuation of character assets.

Although there have been cases of evaluating the value of specific companies or projects which have centralized on developed countries in North America and Europe from the early 2000s, the system and methodology for estimating the economic value of individual technologies or patents has been activated on and on. Of course, there exist several online systems that qualitatively evaluate the technology's grade or the patent rating of the technology to be evaluated, as in 'KTRS' of the KIBO and 'SMART 3.1' of the Korea Invention Promotion Association. However, a web-based technology valuation system, referred to as 'STAR-Value system' that calculates the quantitative values of the subject technology for various purposes such as business feasibility analysis, investment attraction, tax/litigation, etc., has been officially opened and recently spreading. In this study, we introduce the type of methodology and evaluation model, reference information supporting these theories, and how database associated are utilized, focusing various modules and frameworks embedded in STAR-Value system. In particular, there are six valuation methods, including the discounted cash flow method (DCF), which is a representative one based on the income approach that anticipates future economic income to be valued at present, and the relief-from-royalty method, which calculates the present value of royalties' where we consider the contribution of the subject technology towards the business value created as the royalty rate. We look at how models and related support information (technology life, corporate (business) financial information, discount rate, industrial technology factors, etc.) can be used and linked in a intelligent manner. Based on the classification of information such as International Patent Classification (IPC) or Korea Standard Industry Classification (KSIC) for technology to be evaluated, the STAR-Value system automatically returns meta data such as technology cycle time (TCT), sales growth rate and profitability data of similar company or industry sector, weighted average cost of capital (WACC), indices of industrial technology factors, etc., and apply adjustment factors to them, so that the result of technology value calculation has high reliability and objectivity. Furthermore, if the information on the potential market size of the target technology and the market share of the commercialization subject refers to data-driven information, or if the estimated value range of similar technologies by industry sector is provided from the evaluation cases which are already completed and accumulated in database, the STAR-Value is anticipated that it will enable to present highly accurate value range in real time by intelligently linking various support modules. Including the explanation of the various valuation models and relevant primary variables as presented in this paper, the STAR-Value system intends to utilize more systematically and in a data-driven way by supporting the optimal model selection guideline module, intelligent technology value range reasoning module, and similar company selection based market share prediction module, etc. In addition, the research on the development and intelligence of the web-based STAR-Value system is significant in that it widely spread the web-based system that can be used in the validation and application to practices of the theoretical feasibility of the technology valuation field, and it is expected that it could be utilized in various fields of technology commercialization.

This study has examined the allocation of risk in Korea's private provided Infrastructure(PPI) with the following contents (1) Developing a quantitative risk allocation model for Korea's PPI and (2) examining the implication of changes in the minimum revenue guarantees (MRG) clause of government legislation using the developed empirical model. The model of this study adopts and extends H. Yamaguchi's model developed in 2002. To investigate Korea's actual risk allocation deals, the author incorporated the MRG framework. The payment related to the MRG is indeterminable. Hence. the average MRG rate was calculated using probabilistic risk analysis. The risk allocation model is applied to the two eases to validate the model and evaluate the project's VFM(Value for Money). As the revenue guarantee rate is lowered, the government subsidies are increased. This in turn worsens VFM. The same relationship is true when the revenue guarantee Period is shortened.

To quantitatively measure or evaluate aesthetic factors is not easy in comparison with physical, functional, behavioral or economic factors. Yet aesthetic factors essentially play an important role in design modeling process. Despite its importance, research on aesthetic assessment or the interaction of aesthetic influential elements is insufficient. Therefore, this study is intended to find the relationships between visual preference and aesthetic variables of perceptual-cognitive dimension and affective dimension in commercial space design. According to the result of this substantiation research, aesthetic variables that give a positive effect on the preference of commercial space design are unity, order, and clarity in perceptual-cognitive dimension and 'pleasant', 'relaxing' in affective dimension. On the other side, aesthetic variables that give a negative effect on the preference are contrast, complexity, and ambiguity that is a contrary concept of clarity in perceptual-cognitive dimension and 'exciting', 'arousing' in affective dimension.

최근 우리나라는 과거에 비해 기후변화 등의 사유로 가뭄과 홍수가 증가하는 추세에 있으며, '90년대에 들어서는 대규모의 홍수와 극심한 가뭄이 거의 매년 되풀이 되고 있어 지역간 물수급·공급의 불균형이 심각하여 국민이 활용가능한 수자원확보량과 공급가능량이 많은 차이를 보이고 있다. 기후패턴 변화 및 지속적인 용수수요 증가로 인해 가뭄 발생 위험이 커지고 있으나, 신규 수자원개발은 지역갈등 유발 등 사회적 여건에 따라 불가하므로, 기존댐을 평가하고 효율적으로 활용한다는 것은 기존 수자원을 최대한 활용하여 그 가치를 재조명하고 감춰져 있는 수자원을 다시 찾아내어 활용한다는 점에서 큰 의미가 있다. 허나, 댐 용수공급 안정성을 재평가하기 위한 그간 수많은 노력이 이루어지고 있으나, 용수공급 안정성(이수안전도) 기준은 댐 건설 당시 시대적 여건 등에 따라 다르게 적용되어 표준화된 기준이 전무한 실정이다. 이에 따라 국민의 물이용 보장 등 수요자 입장을 고려한 댐별 표준화된 이수안전도 기준 마련이 시급하다고 판단되며, 본 과업을 통해 댐마다 달리 적용된 이수 안전도를 개선하여 형평성을 고려한 국민 물이용 보장 등을 구현할 수 있는 댐 이수안전도 표준화 및 개선방안을 도출하고자 한다. 표준화된 기준을 통하여 신규댐 설계, 기존댐 평가, 갈수 대책용량 결정 등과 관련하여 용수공급 능력 평가 시 혼란을 사전에 예방하고, 본 연구에서는 수자원 시스템의 용수공급 안정성(이수안전도)을 평가하고 표준화 방안을 마련하기 위한 정량적이고 객관적인 지표를 개발하였고 이를 댐설계 기준 등 국가계획에 반영하여 지침 화할 수 있는 방안을 연구하였다.

Game software is tremendous popularity in inside and outside of the country, so it rises market value. Therefore, it is important to study for the evaluation models of game software. In a general way, I think that ISO/IEC 9126 is the international standard of the software quality testing. Especially, game software quality has been more important on users and developers, so we need the compliance testing model of the game software. In this paper, we evaluate the game software quality objectively and quantitatively, we propose the software quality metrics of testing. Also, we propose the evaluation model of game software on the basis of international standard ISO/IEC 9126, six quality characteristic point of view. That is functionality, reliability, usability, efficiency, portability, and maintainability.
