IT system in supply chain management(hereafter, SCM) has been regarded as one of competitive advantage to win over competing supply chain. SCM participants rush to adopt IT system to be agile for changing environment. Companies expect the improvement of the process integration over the supply chain, which enhance the overall SCM performance. IT system has been considered to influence on effective communication over the wall of firm boundaries. But, the profitability or the effectiveness of IT investment are controversial. This study try to reemphasize the importance of IT system considering the differences of processes, and the influences on the collaboration of supply chain participants. We want to know the perception level of functional managers for the importances, usages, and contributions of IT system in manufacturing sector. Also, we compare the different perception for collaborative SCM among supplier, buyer, and employees of buyer, and try to understand the context in which the IT investment acceptance occurs. We collected 297 responses(199 from line process and 98 from project process respectively). Results show that the importances, usages, and contributions of IT system are higher in the line process than in the project process.

This study has developed Web-based, Automated Lesson Planner System for teachers to make out and make use of lesson plans using ICT(Information ＆ Communication Technology). First, web-based lesson planner system has been developed to make teachers possible to make and use lesson plans on the web. Second, the database of electronic lesson planner system has been designed and established according to Korean curriculum and form of teaching-loaming lesson plan using ICT. Third, the system embodied making out a lesson plan easily and operating all ICT materials together. Last, the system was applied to the real elementary school fields and the efficiency and improvements were analyzed. This lesson planner system made database of all ICT materials and lesson plans, so that it can manage and control all lesson plans systematically. Also, the lesson plans and ICT materials are connected together, so the database can be a dynamic content storage. The construction of this system established maximization of share, use and storage of teaching-learning lesson plans. It will be popularize in real education fields and made a contribution to the school informatization.

The researchers developed On-line Lesson Planner System so that teachers can make a lesson plan using ICT(Information & Communication Technology) on line. Developed On-line Lesson Planner System can make ICT using lesson plans store in the database, manage them systematically and help maximize share, use and storage of the lesson plans. It can contribute to the school informatization. It is important to suggest solution through analyzing the educational effects and problems appeared during applying to this developed system in real fields. Thus, this study suggests first, procedure of designing the lesson plan using ICT for the development of this system, second. the summary of designing and embodying methods, and third, the improvement and analysis of the effects and problems revealed in elementary school fields. This study provided educational grounds of the solution to the problems and consideration of this On-line Lesson Planner system.

With rapid advances in IT and introduction to the concept of business process reengineering, many companies have used tremendous resources in implementing ERP systems to improve cost saving and operational efficiency, However, researchers and IT professionals have not clearly explained the roles and values of ERP systems in achieving business objectives. The purpose of the research is to analyze the differences of organizations' performances based on the organizations' ERP readiness, and to identify the roles of ERP systems in enhancing the organizatons' information capabilities and improving business performances, The findings illustrate that ERP systems implementation do not guarantee business performance improvements, and imply that the implementation of ERP systems is likely to enhance organizations' information capabilities, and information capabilities enhanced by the implementation of ERP systems can improve business performances.

Due to COVID-19 and soaring participation of individual investors, large-scale transactions exceeding system capacity limits have been reported frequently in the capital market. The capital market IT systems, which the impact of system failure is very critical, have encountered unexpectedly tremendous transactions in 2020, resulting in a sharp increase in system failures. Despite the fact that many companies maintained large-scale system capacity planning policies, recent transaction influx suggests that a new approach to capacity planning is required. Therefore, this study developed capital market IT system capacity planning models using machine learning techniques and analyzed those performances. In addition, the performance of the best proposed model was improved by using sentiment index that can promptly reflect the behavior of investors. The model uses empirical data including the COVID-19 period, and has high performance and stability that can be used in practice. In practical significance, this study maximizes the cost-efficiency of a company, but also presents optimal parameters in consideration of the practical constraints involved in changing the system. Additionally, by proving that the sentiment index can be used as a major variable in system capacity planning, it shows that the sentiment index can be actively used for various other forecasting demands.

Recently, as the business using IT has increased rapidly, a lot of budget is required to operate and manage the complex IT infrastructure. There is a need for a new IT infrastructure technology that can effectively and reduce costs. In this paper, we introduce CI(Converge Infrastructure) and HCI(Hyper Converge Infrastructure) methods, which are IT infrastructure methods for simplifying information systems and reducing operational management efficiency and cost. In addition, it proposes an information system using the HCI method, a new IT infrastructure technology, and a plan to establish a disaster recovery system to provide continuity of service in the event of a disaster or failure. In addition to the introduction of major technologies for using the HCI method, the area, power consumption, and operational efficiency of the information system before and after the introduction of HCI are compared and analyzed.
