This study theoretically analyzes the cost allocation of replacement costs that occur when existing operators have to replace circuit breakers due to the entry of new generators. We adopt the sequential equal contributions rule as the cost allocation rule, which is widely used in cost allocation problems in cooperative game theory. We derive various cost allocation plans based on several criteria and examine to what extent each alternative meets various desirable axioms. According to the analysis, (i) the alternative that excludes the cost of the new operator, residual value, and network operator and (ii) the alternative that excludes the cost of the new operator, residual value, and includes network operator are relatively superior to other schemes. We also identify a realistic plan by taking into account practical factors and analyze its axiomatic characteristics.

Firms prefer in some specific conditions cooperative R&D to non-cooperative for developing technology. Previous studies on the conditions show firms want to choose cost-sharing type of cooperative R&D (the CS-RJV) rather than non-cooperative one when target technology is either 'relatively easy'or 'relatively difficult', and to join multiple-research type of cooperation (the MR-RJV) than to compete each other if technology is only 'relatively easy'. However, by introducing technological spillover as well as difficult of technology, only if there shown that this seemingly contrasted phenomenon almost disappears : the MR-RJV can i3e also preferred by firms even in case of 'relatively difficult'technology only if there exists some extent of a technological spillover.

The purpose of this study is primarily to analyse empirically the productivity effects of worker participation in capital by Korean employee stock ownership plan that had taken newly effect on and after January 1,2002, and secondarily to examine the impact of unionization on productivity. The analysis data are those of 150 firms that listed or registered on the stock market, and introduced ESOP. The result of this study can be summarized as follows. First, the worker participation in capitia have significantly a positive effect on productivity, but the magnitude of those effects vary according to estimation models and sectors. The elasticity of stock share owned by employees on productivity is from 0.03 to 0.24. Second, there is no unitary relationship between unionization and productivity. The coefficients of union dummy variable are positive or negative according to models and sectors as well as insignificant.

This paper explains that tacit knowledge is a critical component for the success of government-led R&D project selection, where rapid and accurate decision making need to be made under lack of information circumstances. It also explores ways to fully exploit the tacit knowledge of experts participating in the Korean government's R&D project selection process. Some of these include: (1) strategic attention from the top officials, (2) forming self-organizing teams, (3) establishing a horizontal and risk-taking culture, (4) encouraging a sense of responsibility in creating and sharing tacit knowledge, and (5) providing a seamless monitoring system and training.

Previous studies on the conditions show firms want to choose cost-sharing type of cooperative R&D (the CS-RJV) rather than non-cooperative one when target technology is either 'relatively easy' or 'relatively difficult', and to join multiple-research or pararell-research type of cooperation (the PR-PJV) than to compete each other if technology is only 'relatively easy'. However, by introducing technological leakage as well as difficulty of technology. it is shown that this seemingly contrasted phenomenon almost disappears ; the PR-RJV can be also preferred by firms even is case of 'relatively difficult' technology only if there exists some extent of a technological leakage.

Recently, interest in fair tourism and demand for this service has been steadily increasing. This study examined the tourists' perceptions of their fair tourism experiences. Phenomenological method was adopted as a qualitative research approach. Participants were nine adults who were interviewed in depth on their experiences of fair tourism. Data analysis led to the emergence of seven categories (sharing and volunteerism, environment and animal protection, tourism created together, communication and relationship, from consumption to experience, ethicality and fairness, contemplating life) and 21 subcategories. This research was a significant step in providing options to explore the improvement of ethical-tourism and may have implications for the future development of tourism. This study also has various implications for tour operators, consumers, and government. In future all stakeholders should make efforts to establish the tour culture which encourages consumers to consider the ethicality and fairness of their choices as tourists.

Infinite competition on ICT industries is starting again. The basis of competence over global dominance will be human resource, a global ecosystem for products and national agenda for science and technology, etc.. This paper presents the six solution for the Global Competitiveness and Coexistence of Korean ICT Industries. Korea should nurture the brand of "World Best Korean ICT Forever" to secure technical competency of ICT related fields in global market. All ICT technologies should be aligned to global standard and market demand from beginning and the ecosystem around product needs to be established. System framework for utilizing the resource of core SW experts must be established. Through global partnership with China as manufacturing base for Korea-developed products, technical competency can be maintained including product planning. Security measure for technical assets is mandatory. Finally, core technology that will drive the future of ICT industries in Korea should be regarded as core subjects.

This paper examined the leapfrogging of Korean Digital TV Industry in the midst of digital Revolution. Despite the lack of sufficient capability and core knowledge base, the Korean firms succeeded in the catching up forerunner firms in the Digital TV industry. The reasons of the success of Korean firms were as follows. Firstly, the Korean firms had some complementary asset, such as the experience of producing analog TV, and were able to develop the prototype digital TV given the accesses to the foreign knowledge via overseas R&D posts and acquisition of a foreign company. Secondly, the Korean firms were not locked in the analog technologies. As a follower, they had little sunk cost on the existing analog technologies. Thirdly, New mode of innovation, such as National R&D program for the development of HDTV and ASIC, were used as a tool for the mobilization of scarce knowledge base of digital technologies and the sharing the risks of development of path-breaking new technologies.

Owning to rapid infrastructure development, Asia is experiencing dramatic economic growth. There are not a few cases in which, however, economic growth is achieved by increasing the external diseconomy. Pursuit of sustainable development is one of the most important issues for mankind. Under the post-industrial capitalism society, however, there seems a big risk of increase in the external diseconomy worldwide. The objectives of this manuscript are to discuss importance of risk management of construction practice in present and future. Regarding the latter, a particular attempt is made to discuss how project risk communication should be done to reduce the external diseconomy. Presently, one of the important issues in implementation of infrastructure projects is practice of risk management to properly manage time, cost, quality, and safety: mainly maximization of internal economy. Multi-party risk and uncertainty management process (MRUMP) is one of tolls to assist it. The idea on MRUMP can be used to reduce the external diseconomy through identifying, sharing, and tuning people's rhythms.

The purpose of this study was to investigate the relation among family environment variables, self-esteem, family strengths, and achievement motivation. This subjects were the 467 middle school students living in Gwangju. Data were analyzed with SPSS/WIN 20.0 program. The major findings were as follows; First, adolescents' self-esteem, family strengths, and achievement motivation scores were higher than median(3.00). Second, the male adolescents' achievement motivation showed significant positive correlation with standard of living, self-esteem, and family strengths. The female adolescents' achievement motivation showed significant positive correlation with standard of living, father's education achievement, mother's education achievement, self-esteem, and family strengths. Third, the male adolescents' achievement motivation was influenced by self-esteem, role sharing and problem solving, communication and family bonding, and financial stability. And the male adolescents' achievement motivation was explained about 42% by this variables. The female adolescents' achievement motivation was influenced by self-esteem, communication and family bonding, and financial stability. And the male adolescents' achievement motivation was explained about 39% by this variables. Examining the influence of Family Environment variables, self-esteem, and family strengths on achievement motivation of adolescents, self-esteem has the greatest influence and students who think themselves positive and competent has high level of achievement motivation. Adolescents find their own strong point and advantage so that cherish, respect and have proud of themselves.
