본 연구는 기업규모, 장부가치/시장가치 비율, 순이익/주가 비율, 현금흐름/주가 비율, 레버리지 등 기본적 변수를 사용하여 주식수익률에 유의적인 변수를 확인하고자 하였다. 이를 위해 본 연구에서는 횡단면 자료와 시계열 자료를 결합한 패널자료(panel data)를 이용하여 패널자료분석방법으로 연구모형을 실증적으로 분석하였다. 일반적으로 패널자료를 사용하면 Hsiao(2003)가 지적한 바와 같이 표본의 크기를 확대시켜 자유도를 증가시키고 이론적으로 설명변수간 다중공선성(muti-collinearity) 문제를 완화할 수 있다. 실증분석결과에 의하면 기업규모(SIZ), 장부가치/시장가치 비율(B/M), 순이익/주가 비율(E/P), 현금흐름/주가 비율(C/P) 등이 주식수익률의 횡단면적 차이를 설명할 수 있는 유의적인 변수라 할 수 있다.

This paper examines the time-series relations among expected return, risk, and book-to-market(B/M) at the portfolio level. The time-series analysis is a natural alternative to cross-sectional regressions. An alternative feature of the time-series regressions is that they focus on changes in expected returns, not on average returns. Using the time-series analysis, we can directly test whether the three-factor model explains time-varying expected returns better than the characteristic-based model. These results should help distinguish between the risk and mispricing stories. We find that B/M is strongly associated with changes in risk, as measured by the Fama and French(1993) three-factor model. After controlling for changes in risk, B/M contains little additional information about expected returns. The evidence suggests that the three-factor model explains time-varying expected returns better than the characteristic-based model.

Annual total values and thereby assets values of natural resources are determined by sample household WTP estimates and the extent of market. In the current domestic practice of CVM, total numbers of national households were used as the target population to measure total economic values including non-use values. This study proposed an alternative method of calculating potential user groups based on distributions of residential area of visitors in the sample using 4 provincial parks in the Chon Buk area as cases. The sample mean of WTP of Moak Mt. visitors, who are mostly from the nearby Chon Buk provincial area, was estimated to be about 8,215 won. On the other hand, the mean of WTP of Sun Woon Mt., whose visitors are evenly distributed from all over the country, was about 4,693 won. When applied national households as the target population, annual total benefits and thereby asset values of Moak Mt. was high enough to be 86 billion and 1.6 trillion won respectively. However, those of Sun Woon Mt. was low to be 52 billion and 1 trillion. On the contrary, when applied potential user groups of each park as the extent of market, annual total benefits and asset values of Sun Woon Mt. was reversed to be high--23 billion won and 400 billion won respectively. However, those of Moak Mt. was lowered to be 10 billion won and 200 billion won. Furthermore, asset values of the same park were differed by 2 to 8 times according to the way of setting the extent of market.

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.

Given the rapid changes in consumer tastes, technology, and competition, companies must develop a steady stream of new products and services. To be a successful product or service and explore the available market, the target market consumers need to be fully acknowledged a new product or service's value or benefit. And at the same time, the presented benefit should satisfy the customer's needs and wants. Therefore, a firm must investigate the target consumers' needs and wants before launching the new product or service. In this paper, we suggest the marketing strategy for newly developed WiBro service in telecommunication industry. We focus on consumer-oriented marketing strategy as well as the technology development process. To explore the customer's value scheme, we employ a self-explicated approach for estimating the customer's part-worth of the different target market in the process of market development stage. And we present the marketing strategy for each market development stages as well.

본 연구에서는 기존에 존재하는 제품을 대체하고 보완하는 기능을 가진 새로운 유형의 컴퓨터가 시장에서 받아들여지지 않아 실패하는 요인을 연구하였다. 제품실패의 원인을 소비자가 제품의 가치를 부정적으로 지각하는 것에 두고, 가치 지각에 영향을 주는 요인들을 소비자가 제품을 사용하여 얻게 되는 혜택과 제품을 사용하는데 소요되는 비용으로 구분하여 영향관계를 파악하였다. 넷북을 대상으로 실증 연구한 결과 소비자가 신제품의 가치에 대해 부정적으로 지각하는 것은 사용의도에 부정적으로 영향을 미치는 것으로 나타났다. 그리고 소비자가 새로운 유형의 컴퓨터에 대해 지각하는 비용은 신제품의 가치를 부정적으로 지각하는데 유의하게 영향을 미치는 것으로 나타났다. 다만 소비자가 새로운 유형의 컴퓨터에 대해 혜택을 부정적으로 지각하더라도 이는 가치를 부정적으로 지각하는데 영향을 미치지 않았다.

We aim to confirm empirically that a corporate's R&D expenditure effect positively on its value. As a result of the regression analysis on financial statements of KSE and KOSDAQ enterprises, the sum of R&D expenditure effects positively on corporate value. Moreover, we have the result that R&D expenditure appropriated as cost has more effect on corporate value than the expenditure appropriated as asset.

고객가치에 기반을 두지 않은 소프트웨어는 블루오션을 창출할 수 없고, 기존 시장에서 우위를 점유할 수 없으므로 최근에는 고객가치와 품질 향상에 초점을 맞춰 소프트웨어 개발이 이루어지고 있다. 또한 시장에서 우위를 차지하기 위한 중요한 요소 중 하나가 비용인데, COTS 기반의 개발방법은 시장출하 시간의 단축과 비용절감의 효과가 있어 관심이 증가하는 추세이다. 본 논문에서는 고객가치를 창출하고 소프트웨어 품질을 향상시키기 위해 고객가치와 COTS의 품질속성을 고려하여 COTS를 선택하는 요구공학방법론을 제시하였다.
