Purpose This study examines firms at various industries to identify key organizational characteristics that positively drive the evaluation of cloud computing. In addition, this study tests the impact of one's evaluation has on the adoption and integration of cloud computing within their respective firm. Design/methodology/approach A total of 172 responses from various firms currently using cloud computing service were analyzed using the structural equation modeling(SEM). Findings Results show that organizational Needs(Mobility and Job Relevance), Perceived Factors(Relative Advantages and Cost Savings), and Organizational Readiness(Technical Knowledge, Financial Supports, and Managerial Supports) have a significant impact on cloud computing evaluation; and evaluation influences its adoption, and integration. However, two variables(IT Performance Gaps and Compatibility) have no significant impact on cloud computing evaluation. Finally, Evolutional Leadership has a significant moderating effect within the relationship among variables in the process of cloud computing implementation.

Long-term relationship in distribution channels has been emphasized in the former researches. But many researches and literatures have not focused on how to achieve and maintain long-term relationship. To achieve and maintain long-term relationship, this study pays attention to the role of trust and commitment. The purpose of this study is explaining the relation between trust and commitment with the mutual perspectives of retailer and supplier. Research results indicate that trust has an effect on commitment, trust has two levels of firm and a responsible person, and perception of partners commitment has an effect on trust in two levels. And it shows that to increase perception of commitment, increasing commitment, quality of communication, satisfaction, reputation, and decreasing opportunistic behavior should be considered.

Weather derivatives designed to manage casual changes of weather, as opposed to catastrophic risks of weather, are relatively a new class of financial instruments. There are still many theoretical and practical challenges to the effective use of these instruments. The objective of this paper is to develop a pricing approach for valuing weather derivatives and presents a case study that is practical enough to be used by the risk managers of electrical utility firms. Utilizing daily average temperature data of Guangzhou, China from $1^{st}$ January 1978 to $31^{st}$ December 2010, this paper adopted a univariate time series model to describe weather behavior dynamics and calculates equilibrium prices for weather futures and options for an electrical utility firm in the region. The results imply that the risk premium is an important part of derivatives prices and the market price of risk affects option values much more than forward prices. It also demonstrates that weather innovation as well as weather risk management significantly affect the utility's financial outcomes.

This study evaluates how activation plans presented by previous research are perceived by employees in the ship supply industry by sample surveys. Another objective of this study is to also assist in the selection of effective activation plans. It is becoming more and more difficult for the Port of Busan to strengthen its competitiveness in the ship supply industry by maintaining the status quo. Much research extending the scope of research subjects in the port logistics industry indicates that the development of the port logistics industry is very important for creating new value for the Port of Busan. The results shows that improvement in the retail structure and government support had a significantly positive correlation between the importance and necessity of the ship supply industry activation.

This study aims to develop strategic diagnosis framework of performance by identifying and analysing the dynamics of the technology commercialization ecosystem in innovative region. To achieve the purpose of this study, the systems thinking approach is used. The systems thinking approach connects feedback structure and behavior more explicitly to diagnosis vicious feedback loop in the regional technology commercialization ecosystem. In terms of an ecological point of view, it will be possible to explore dominant feedback structure and find leverages to overcome the limitations of regional technology commercialization performance. The diagnosis of reenforcing and balancing feedback structure is based on the statistical analysis of the survey data which has been collected in a cluster random sampling method, targeting on the 200 firm located in the Pangyo and Daeduk region. The results from this research showed that the regional technology commercialization ecosystem was immature and faced limit to the growth. An important finding of this study was that regional technology commercialization ecosystem need to activation of startups and reinforcement of virtuous feedback structures of technology commercialization market systems.

Leadership is one of the most widely explored subjects in the field of management. A variety of papers on leadership, however, still have insufficient aspects to reveal the theoretical logic about the CEO leadership itself. Such research, especially focused on organizational performance, tend to concentrate on the CEO's behavior rather than leadership because CEO's behavioral trait as an explanatory variable is useful to connect with firms' performance. Our purpose is to show how the characteristic of CEO leadership can be built at the organizational level. For a detail, the larger the firms' size, the greater the degree of CEO's charismatic leadership. The larger the degree of a firm's diversification, the greater the degree of the CEO's transformational leadership. And the less the degree of a firm's diversification, the greater the degree of the CEO's transactional leadership. This theoretical paper on CEO leadership suggests that the characteristics of CEO should be adaptable to the changing institutions and organizational environments.

NAVER provides search frequency data of search terms via its DataLab service (http://datalab.naver.com/). Using this data, this paper examines the relation between the search frequency of firm's name and its future stock returns. Our results show that the search frequency of firm's name is a new investor attention measure, which is different from previously explored attention measures such as extreme returns, turnover, etc. Firms that go through higher search frequency this week tend to have higher returns in the next week. We do not find return reversal in the long run for the firms with higher search frequency. Furthermore, the extent to which search frequency affects stock returns becomes more pronounced following market-wide attention grabbing events. Our results indicate that search frequency incorporates information for future stock returns.

This study investigates whether earnings management behavior of chaebol firms differ from that of non-chaebol firms. The ownership structure of chaebol firms is characterized by the dominance of one largest shareholder and his family members who typically participate in the management of the firm directly or indirectly and influence most of the important management decision. This study adopts the random effect model and the hausman and talyor model, using a panel of 5092 firm-year over a period from 1991 to 2010 to control for potential heterogeneity and endogeneity that may cause sever bias. This study finds that there is no difference in accrual based earnings management level between chaebol firms and non-chaebol firms. However, chaebol firms appeared to engage less real earnings management that is known to negatively affect future earnings and share prices. The results are consistent when controlling for potential heterogeneity and endogeneity in the hausman and taylor model. The results may be of interest to various stakeholders, policy makers, standard setters and academic researchers.

The importance of Corporate Social Responsibility (CSR) implementation is increasing and CSR activity has become a core activity for firms. The increase on CSR activity expenditures also increases the need for strategic. When firms implement CSR strategically, firms need to consider consumers' perspectives toward CSR. This research investigated how Korean fashion companies integrate consumers' CSR expectations into CSR implementation. Through a qualitative study, we researched a firm's consideration of consumers which are reflected in detailed procedures of CSR implementation. We conducted in-depth interviews with executives and managers in charge of CSR and found the following results. First, motivations for CSR implementation were both strategic and moral along with consumers who play a crucial role in CSR motivation. Second, firms conducted various strategic CSR activities differentiating themselves using a specific resource. Third, self-CSR evaluation was not active and structured. Few companies were collecting consumer responses to CSR activities. Last, executives and managers have difficulties to perform CSR activities due to gaps between ethical consumption consciousness and the ethical consumption behavior, measurement of CSR effect, and lack of understanding of strategic CSR. The results of our study show that firm's consideration of consumers is insufficient despite executives and managers who strongly agree with the need for strategic CSR.
