This paper proposes a new approach to technology valuation, the market-replacement cost approach which integrates the cost-based approach and market-based approach. The proposed approach estimates the market-replacement cost of a target technology using R&D costs of similar R&D projects previously conducted. Similar R&D projects are extracted from project database based on document similarity between project proposals and technology description of the target technology. R&D costs of similar R&D projects are adjusted by mirroring the rate of technological obsolescence and inflation. Market-replacement cost of the technology is then derived by calculating the weighted average of adjusted costs and similarity values of similar R&D projects. A case of "Prevention method and system for the diffusion of mobile malicious code" is presented to illustrate the proposed approach.

In this paper, we propose the rough set approach to extract trading rules able to discriminate between bullish and bearish markets in stock market. The rough set approach is very valuable to extract trading rules. First, it does not make any assumption about the distribution of the data. Second, it not only handles noise well, but also eliminates irrelevant factors. In addition, the rough set approach appropriate for detecting stock market timing because this approach does not generate the signal for trade when the pattern of market is uncertain. The experimental results are encouraging and prove the usefulness of the rough set approach for stock market analysis with respect to profitability.

The purpose of this study was to investigate the present state of e-business according to the establishment year and the sales approach of Dongdaemun clothing market and to present problems according to e-business activation of it and its developmental direction. The subjects for this study were selected out of Dongdaemun clothing markets being considered as more fashion-oriented markets and were divided into two categories both according to the establishment year and according to the sales approach. As a result, Dongdaemun clothing markets are mainly divided into traditional wholesale market, eastern wholesale & retail market, and western retail market and having dealings with each other according to the market's characteristics. The utility percentage of on-line e-business according to the establishment year and the sales approach showed that traditional wholesale market was 42%, eastern wholesale & retail market 0.75%, and western retail market 11%. This result indicated that the utility percentage of traditional wholesale market showed much higher than eastern wholesale & retail market and western retail market. This would be because the structural characteristics of clothing market delayed the utility of e-business. For the problems on the utility of on-line e-business through counselling, traditional wholesale market showed much higher than wholesale & retail market and retail market because it had little problems on design imitation in retail market due to export by order and mass production. The problems of low utility of on-line e-business in Dongdaemun clothing market would result from well-timed on-line update according to rapid goods cycle, constant satisfaction for additional order, standardization of size and quality, and inexpensive internet purchase despite of express expense.

시장구조 분석에서 흔히 사용되는 상표전환 자료는 비내구재 분석에 적절한 방법이 될 수 있으나 자동차 같이 사용연한이 장시간인 내구재의 경우에는 소비자의 상표에 대한 선호도가 변할 수 있어 상표전환 자료의 사용에 문제가 있다. 따라서 경쟁을 잘 포착할 수 있는 다른 접근이 필요하다. 본 연구는 이에 대한 대안으로 상표간 경쟁 자료로써 고려상표군을 이용하여 자동차 시장의 구조를 Latent Class 군집분석을 활용한 탐색적 검증방법으로 분석하였다. 또한 소비자 행동분석에 근거하여 상표간 경쟁의 근간을 이루는 고려상표군 형성에 영향을 미치는 인자들을 밝히는데 중점을 두었다. 미국 자동차 시장을 대상으로 분석한 결과, 시장은 상표 원산지 효과에 의해 구분되었다. 즉, 미국 상표, 유럽 상표, 그리고 아시아 상표 등으로 시장이 구분되었다. 또한 각 시장구조 내 소비자들의 고려상표군 형성에 신뢰성/안전, 이미지/즐거움, 경제성 등의 편익과 성별, 소득 등 개인적 요인이 영향을 미치는 것으로 나타났다.

본 연구에서는 시장세분화의 기준들이 가질 수 있는 다차원적인 특성들을 고려하여 시장 세분화를 순차적으로 접근하였다. 소비자들이 유통형태를 선택할 때 추구하는 해택을 중심으로 순차적 세분화를 분석하기 위하여 서울시내의 20세 이상 55세 미만의 가정주부들이 모집단으로 정의되고, 이 중에서 할당추출방법에 의해 수집된 1000명의 표본이 이용되었다. 애프터서비스 추구혜택 세분시장 이외에 4개의 세분시장을 각 세분시장의 1차 추구혜택변수에 부가된 2차적 혜택변수를 기준으로 군집분석을 실시한 결과, 각 세분시장은 2개의 또 다른 하위세분시장으로 나누어졌다. 끝으로 이러한 결과의 시사점이 논의되고 연구의 한계점과 미래의 연구방향이 제시되었다.

This study secured comparable sales transaction information of technology transfer corresponding to an active market conditions and proposes a method to assess the similarity of technologies with regard to comparability of technology transfer based on these cases information. In order to analyze the association and similarity between target technology and sales transactions, it proposes the significant factors affecting royalty decision and the cosine coefficient method by industry categories. It also proposes the method to adjust royalty, which means that this method unlike the conventional method provides clear standards to valuators in order to revise royalty. Therefore, it offers a solution to the difficulties of applying the market approach for a lot of valuators that have wanted to apply it and objective method to enhance the reliability of the value of intangible asset evaluated by the market approach.

본 연구에서는 시장접근법 기반의 기술가치평가를 위한 원리적인 개념 모형을 제안한다. 하나의 기술이 기술성과 사업성을 기초로 기술가치를 부여받고, 다시 그 기술가치가 시장가치로 전이되는 개념모형을 제시하고 그 논리적인 타당성을 논의한다. 기술대가 지불방식의 두 가지 형태인 정액기술료 및 경상기술료 방식 각각에 대해, 기술-기술가치-시장가치 전이모형을 구성하는 구체적인 요인들을 식별하고 측정방식을 분석함으로써 구체화된 시장접근법 기반 기술가치평가 개념 모형을 개발한다. 더불어 본 연구에서 제안하는 개념 모형을 이용하여 기술가치평가의 세 가지 접근법인 비용-소득-시장접근법간의 관계를 설명할 수 있음을 보인다.

This paper proposes a new method to handle transmission line losses using loss distribution factors (LDF) rather than marginal loss factors (MLF) in electricity market operation. Under a competitive electricity market, the bidding data are adjusted to reflect transmission line losses. To date the most proposed approach is using MLFs. The MLFs are reflected to bidding prices and market clearing price during the trading and settlement of the electricity market. In the proposed algorithm, the LDFs are reflected to bidding quantities and actual generations/ loads. Computer simulations on a 9-bus sample system will verify the effectiveness of the algorithm proposed. Moreover, the proposed approach using LDFs does not make any payments residual while the approach using MLFs induces payments residual.

The u-City construction project has become a hot topic in the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because environments of the future business for the u-City are very uncertain. Scenario planning is a very powerful method in managing this uncertain planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market in S.Korea through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Finally, we developed three coherent u-City construction market scenarios. Construction firms can use these scenarios as a basic reference for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.
