Economic value added (EVA) is introduced on two levels: as index for evaluation of corporation and as index for evaluation of business unit. In the latter case, application of one and the same cost of capital to all business units of a business corporation may be possible, but it is a fundamental policy for EVA to apply different cost of capital to business units with different risks. Estimate of cost of capital of business units is a problem to be resolved. The author, focusing on the question of the estimate of cost of capital of business units, has conducted a demonstrative study on risk structure of cost of capital estimates by using financial indices of Japanese manufacturers (37 automotive industries, 141 electrical and electronic machinery industries, 63 food processing industries, 98 chemical industries, 125 general machinery industries) for a period of 5 years from 1995 to 1999. The author presumes that $\beta$ is explained by a regression formula ${\beta}=B_0+{\Sigma}B_iY_i+{\alpha}$ ($Y_i$: financial indices) and selects 40 explanatory variables from financial statements as risk components. Using their financial indices, the author concludes through a series of statistical analyses that there is a good likelihood of estimating cost of capital for Japanese industries and is convinced that it will lead to more reliable and practical results by assigning averages and variances to 40 primary financial indices for a period of 3 to 5 years selected in this demonstrative study.

이 글은 저작권법상 법인에게 저작자 지위를 귀속시키는 업무상저작물제도를 보완하여 게임 개발자의 권리를 강화함으로써 개발자의 창작의욕을 고취하고 이직 및 기술유출과 관련된 분쟁을 미연에 방지하여 산업발전을 촉진할 수 있는 방안을 찾는 것을 목적으로 하였다. 이를 위해 기능성저작물과 문예저작물의 복합적 성격을 띤 게임의 특성에 비추어 일반적인 산업저작권의 개발자와 비교하여 두텁게 보호될 필요가 있는지 그리고 보호의 필요가 있다면 어떠한 방법이 가능할 것인지를 검토하였다. 구체적으로 그 보완 방법을 세 측면으로 나누어 분석하였다. 첫번째 측면은 업무상저작물제도를 엄격하고 제한적으로 적용해야 한다는 해석론적 관점과 법적으로 저작인격권의 보호를 인정하여야 한다는 입법론적 관점을 살펴보았다. 두 번째 측면은 다수의 저작자가 관여하는 온라인게임 개발에 있어서 저작인격권을 인정하고자 하였을 때 문제가 되는 부분인 공동저작자 인정 여부와 관련된 학설과 판례를 검토하였다. 끝으로, 현실적으로 저작인격권을 보호하는 것이 용이하지 않을 때에 직무발명의 보상청구권 청구 규정을 유추하여 개발자의 경제적 이익을 확보할 수 있을 것인지 검토하였다.

Corrosion of the Cu alloy with 10wt% Ni in stagnant seawater with residual free chlorine was investigated. Despite that fact that Cu alloys are widely used for seawater applications due to their stubborn resistance to chloride attack, not much is known as to how the residual free chlorine in seawater affects corrosion of Cu and its alloys. In this work, immersion tests were conducted in the presence of different levels of chlorine for 90-10 Cu-Ni samples, one of the most frequently used Cu alloys for seawater application, mostly in shipbuilding. The results revealed no evidence for accelerated corrosion of the Cu-Ni alloy even in the presence of 5 ppm residual chlorine in seawater, signifying that the Cu-Ni alloy can be more tolerant to residual chlorine that has been commonly cited by the shipbuilding industry. However, comparison of polarization behavior of the alloy samples in the presence of different electrolytes with different concentrations of residual chlorine suggests that higher concentration of chlorine could increase the corrosion rate of the Cu-Ni alloy. Furthermore, it is suggested that microorganisms in the seawater could increase the corrosion rate of the Cu-Ni alloy by encouraging exfoliation of the corrosion product off the metal surface.

This study investigates employees' online reviews, conducts in-depth text topic mining, effectively summarizes the dimensions of employer brand value, and seeks effective ways to build employer brands from a multi-dimensional perspective. This study employs samples of employer reviews, filter keywords according to word frequency-inverse document frequency, builds a review network containing the same keywords, explore the community and summarize the theme dimensions. Simultaneously, it makes a dynamic comparison and analysis of the employer brand value dimension of different industries and enterprises. The study shows that the community exploration theme can be summarized into 11 dimensions of employer brand value, and the dimensions of employer brand value are significantly different across industries and among different enterprises within the industry. The attention to the employer brand value dimension has a significant time change. Various industries pay increasing attention to the dimension of work intensity and career development, while employers pay steady attention to the dimension of welfare benefits. The findings of this study suggest that seeking the heterogeneity of employer brand resources from the multi-dimensional differences and changes is an effective way to improve the competitiveness of enterprises in the human capital market.

Purpose: This study aims to develop measuring tools for 'Consumer Issues' of ISO 26000, the international standards for corporate social responsibility(CSR), and propose strategic suggestions on the CSR implemention by analyzing the differences among various industries. Methods: In order to test the research models, structured questionnaires were used and nationwide surveys were conducted targeting at customers who have had experiences in using the products and services from the companies which published CSR reports. In addition, for the empirical analysis of data, the models were verified with AMOS confirmatory factor analysis(CFA). Results: From the result of the analysis of differences among industries, it was shown that level of CSR activities was high in public sectors, followed by service industries and manufacturing. It was also shown high in air transport and the electrical and electronic industries, while it was confirmed low in energy and environment related industries such as energy, automobile and chemical industries. As a result, strategic approaches are suggested, considering the different characteristics of each industry in implementing CSR. Conclusion: This study has developed measuring tools for 'Consumer Issues' to research the core subjects and issues of ISO 26000, the international standards for CSR. It has confirmed the characteristics and differences regarding 'Consumer Issues' among industries and proved that industries can provide guidelines for the implementation of CSR activities through approaching and researching various issues from interested parties. This study has also suggested the importance of customer awareness of CSR activities and active communications by industries.

The content industries environment has been undergoing significant changes due to rapid technological innovation and content market expansion. Interest in the industry is growing fast both in Asia and Europe. However, in Japan content industries are showing almost zero growth with no increase in overseas expansion. Until now, Japanese content industries have been able to grow based on domestic demands. Many different factors contributed to today's zero growth in Japanese content industries. Two main reasons are: 1) Their lack of interest in overseas expansion and 2) Insufficient investment in domestic human resources development. Considerable amounts of Japanese contents including films, music, games, and animations have been distributed in many Asian countries and today piracy problems in the region are at a serious level. According to 2004 records pirated editions accounted for 85%, 16%, 19%, and 36% in China, Korea, Hong Kong, and Taiwan respectively. Pirated editions bring economic losses to Japanese copyright profits. Making it worse, they weaken the motivation to create content and make it hard to activate cultural exchanges. Losses from copyright violations in Japanese content industries are expected to keep increasing in the future. In order to make Japan competitive and grow it is crucial to take proper measures to protect copyright infringements. This study considers the current situation of the Japanese content market, infringement issues in content which is causing many problems in Asian countries, including China, and facts about losses caused by this problem.

This paper presents a new method for multiobjective optimization using Genetic Algorithm-Sexual Reproduction Model(SR model). In SR model, each individual consists of chromosome pairs. Sex cells(gametes) are produced through artificial meiosis in which crossover and mutation occur, The proposed method has two selection operators, one, individual selection which selects the individual to fertilize, and the other, gamete selection which makes zygote for offspring production, The two selection schemes are repectively conducted according to different fitness(or objective) function and consequently give a solution which is unbiased to any objectives. We apply the proposed method to optimization of the design parameters of Linear Induction Motor(LIM) and show its effectiveness.
