Hydro-electric power generation from multi-purpose dams has been playing important roles in the electric power supply network in Korea. Although the total share of hydro power in national electricity supply now becomes very small, the peak-shaving and frequency control capability of hydro power helps the power company enormously in maintaining the quality of power. But since the company that builds and operates the multi-purpose dams in Korea has to sell all the electricity produced to the monopolistic utility, there have been various problems in justifying the investment, designing pricing mechanism, and controlling operations of the power plants. In addition, economic evaluation of the hydro power has been distorted by a variety of reasons and hence it has been very difficult to encourage effective development and utilization of national water resources. To make the problem worse, both parties are public companies with X-inefficiency problems. Thus, changing environment requires to reengineer the system that governs hydro power generation. We address the problems of Korean hydro-electric power generation system in four areas: the investment justification process, the operations decison right of the hydro power plants, the pricing of the purchased-power, and the negotiation of contract revision. Then we propose improvement directions of new hydro-electric power system in view of static and dynamic efficiency, X-inefficiency and equity.

Purpose - This paper aims to examine the impact of buyer-supplier cooperation on suppliers' trust on buyers and the moderating role of buyers' governance mechanism between the sharing activities and trust. Research design, data, and methodology - An integrated research model is designed to materialize the research hypotheses. First, the impact of buyer-supplier cooperation is empirically analyzed by looking into how the sharing activities, in the field of information, resource, and knowledge, of buyer with supplier will affect the trust of supplier on buyer. Second, the moderating effect of contract-based governance mechanism of buyer is empirically analyzed. Third, the influence of trust on innovation performance of suppler is empirically analyzed. Results - Our findings provide supporting evidence for some of our hypotheses. First, all of the sharing activities are significantly influential, but in different degree, to trust of supplier. Second, contract-based governance mechanism of buyer have a moderating effect on the relationship between sharing activities and trust, positively in resource-sharing activities, negatively in information-sharing activities, not significant in knowledge-sharing activities. Third, supplier's trust on buyer positively affects supplier's own innovation performance. Conclusions - The strategies applied in supply chain management have become important as the competition among firms has shifted from competition between individual firms to competition between supply chains. A customer's sharing activities with its supplier may contribute to an increase in innovation performance. The supplier's information-sharing activity with its customer could affect its information-sharing activities with its main supplier. Cooperative activity with a partner in the supply chain is cultivated and amassed into relationship knowledge, and this study shows that the cooperative relational knowledge related to information-sharing activities enables firms to participate in sharing activities with their main suppliers. Increasing evidence shows that sharing various activities between buyer and supplier improves trust and performance outcomes, and enables firms to maintain competitive advantage. From the perspective of knowledge theory, external knowledge is becoming more important in firms' innovation activities, because innovative knowledge is acquired primarily through interaction with another organization. In addition, relationship learning could be an important tool in absorbing the supplier's core technology, information, expertise, and core competencies, increasing relational value.

Application software is delivered to customers as a form of service at cloud environment. A cloud service provider is a marketplace between supply side (application providers) and demand side (customers). Cloud service providers have to validate applications to be included in their service portfolio. Not only performance, security, networking, compliances should be checked but also business contract, authentication should be provided. Organization customers are more sensitive to these validation criteria and process. We study the Internet2 NET+, which is a successful cloud marketplace of applications for research and education organizations. This case study shows us three things : (i) a cloud marketplace's application management process : selection, validation, transition to service, customization of applications (ii) what a cloud marketplace has for its infrastructure like authentication, security, access control etc. (iii) what a cloud marketplace has as its governance structure. This case study will provide informative analysis of Internet2 NET, a profit-making vertical and buyer's marketplace (education industry). And we will get some strategic implications for planning and implementing cloud marketplaces.

Most of the Chinese immigrants in the 19th century migrated to the eastern part of the Malay Peninsula via Penang. At that time, the British colonial government recruited Chinese immigrants to supply Chinese labor. The influence of the Chinese in Penang has been greatly increased due to the continuous influx of Chinese immigrants. Specifically, looking at Chinese immigration, from 1805 to 1815, a large number of Chinese labor migrants, from about 500 to 1,000, arrived from Macao to Penang, Malaysia, and they were all contract migrants. In the late 19th century, most of the Chinese in the Malay Peninsula were resettlement from Penang and Singapore. At that time, the Malay Peninsula desperately needed to clear the jungle for farm development, and thus a large-scale labor force was needed. Therefore, the Chinese labor force that was overflowing in Penang and Singapore was able to meet the demand for labor in the Malay Peninsula.

This paper deals with disputes incurred from the CISG provisions in relation with the conformity of goods with a view to finding the general way of approach made by the court and arbitration tribunal in the case laws for the interpretation of CISG based on 6(six) cases thereon. Throughout this study, it has been noted that the German Supreme Court devoted most in creating the general principle of CISG interpretation in relation with national compulsory law of regulation applicable on the conformity of goods. It was New Zealand mussels case in which the German supreme court decided that the exporting country's compulsory law of regulation would be applied in determining the conformity of goods. Furthermore, German supreme court added that CISG does not place an obligation on the exporter to supply goods, which conform to all statutory or other public provisions in force in the import state unless the same provisions exist in the export State as well, or the importer informed the exporter about such provisions existing in the import state, or the exporter had knowledge of the provisions due to special circumstances. It is stipulated in CISG that the goods conform with contract if they are fit for the purpose for which goods of the same description would ordinarily be used. When questions arise concerning matters governed by the CISG that are not expressly defined in the CISG, the question is to be settled in conformity with general principles on which the convention is based. Only when such a general principle cannot be found may the tribunal turn to other sources such as UNIDROIT Principles, Principles of European Contract Law and Lex Mercatoria, etc. Interpretation of CISG should be autonomous, in the sense that it should not depend on principles and concepts derived from any national legal system. Even where a CISG rule is directly inspired by domestic law, the court should not fall back on its domestic law, but interpret the rule by reference to the CISG with a view to its international character and to the need to promote uniformity in its application and the observance of good faith in international trade.
