Recently, We will analyzed the effects of supply chain management(SCM) execution factors on the competitive advantage, focusing on display industry, which is the most intense sectors in global competition. It is important for global companies to secure corporate agility to actively respond to rapid changes in the market. This study examines whether business agility influences competitive advantage and plays a mediating role between performance and competitive advantage considering market situation.. As a result, it was analyzed that three variables of strategic factors such as strategic partnership, information sharing, and information technology have statistically significant effects on firm agility and competitive advantage. Also, it is proved that corporate agility is mediating effect on SCM execution factor and competitive advantage. This study suggests that SCM in global manufacturing industry is a Business Management System(MIS) that must be operated in enterprise management.

This study presents the linkage method combining the existing Port Management Information System (PORT-MIS) DB with the scattered vessel activity data sets including the hotelling and maneuvering characteristics and specification information of the vessels arriving and departing from the port of Busan from January 2009 to June 2010. By linking the data sets, this study made three types of vessel activity databases: L-PORT-MIS DB with low-level vessel activities, M-PORT-MIS DB with medium-level vessel activities such as hotelling time, H-PORT-MIS DB with high-level vessel activities such as hotelling time, engine power, etc. The greenhouse gas (GHG) emissions estimation results show that total GHG emissions decreases when the detailed vessel activities are employed. This decrease in the total GHG emissions by the level of vessel activities implies that the GHG emissions from the low and medium level vessel activities are overestimated due to the aggregated hotelling/maneuvering times and speeds resulting from the past vessel specifications. Therefore, the GHG emissions using the H-PORT-MIS DB are more reliable GHG emission estimates in that the vessel specifications and the observed hotelling time of each vessel are employed in the estimation process. Hence, the high-level vessel activity dataset should be constructed to implement more suitable countermeasures for reducing the GHG emissions in the port of Busan.

The advent of information communication technology or the Fourth Industrial Revolution facilitated the fusion of equipment and management systems, such as Manufacturing Execution System, Enterprise Resource Planning, and Product Lifecycle Management, in the successful implementation of smart factories. The government supports the early adoption of these systems in small and medium companies to enhance their global competitiveness in producing products that can be recognized in a dramatically changing manufacturing environment. This study introduces smart factories to improve company competitiveness and address influences from the government assistance, CEO leadership, external consultancy, and organizational participation. We analyzed 101 results received from the questionnaires circulated to small- and medium-sized manufacturing companies. Given a successful smart factory implementation, company competitiveness is the factor that mostly influences organizational participation, government assistance, external consultancy, and CEO leadership. This study suggests several perspectives to implement a smart factory, which is the most important aspect of company competitiveness.

This study is intended to identify the factors affecting the successful information warehouse (IW) implementation through the technology acceptance model. As the IW has played an important role with the organizations, it has become a strategic management tool. However, because the building of an IWS requires a great amound of financing and a multi-period, managers should consider identifying the variables as a predictor of IWS success. The related research areas, such as TAM , TRA, and innovation diffusion theory, and previous research associated with the EWS success factors are reviewed in this paper. Based on the hypotheses presented , the study will empirically test the relationships between six external variable-user involvement, computer self-efficacy, OLAP characteristics, problem difficulty , user training and top management support-and system utilization via user's perceptions of ease of use, unusefulness. This study semmes to be a first attempt in this research area, and its results will provide general guidclines for IWS project managers to enhancement the like hood of system succes.

There are many studies on the project planning, project management and quality management. The cost of the new project takes only 20% of system's lifetime resource and the costs of the maintenance and infrastructure take more than 80%, so the study on the maintenance is much more important than the study on the new project. There has been many studies on the economic life cycle of the system using it's maintenance cost, but no studies on it's infrastructure cost. This paper provides how we can adapt infrastructure cost, which takes more than 40% of system's life cycle cost, to the economic life cycle of the system and its effects on the system's economic life cycle.

ISP(Information Strategy Planning) is the methodology to light the objective and the business system architecture, and to recognize the strategic situation for the establishment of effective information system in an organization. Customer Needs Research is one of the Research Methodology that analyze the customer needs effectively and use to establish the policy and the direction of corporation. Both have the important role to establish the strategy for the corporation. The former can propose the corporate information strategy in MIS, the latter can be used to research the customer needs about a corporation, to establish the business management strategy and to decide the way corporate must head. But each has studied independently and there is no integrated methodology of ISP and Customer Needs Research. Actually, a lot of corporations still establish ISP to increase the business efficiency rather than to satisfy the customer needs. Customer satisfaction is the final objective of all business so that corporations have to find the customer needs through Customer Needs Research and make ISP oriented to customer satisfaction through the result of Customer Needs Research.
