This paper discusses a scheduling problem on object-oriented developments over multiple teams with limited resources in matrix organization. The objective of the problem is to minimize the makespan of overall projects. There are tangible and intangible advantages such as efficient resource share, improvement of productivity, development efforts and cost reduction, etc. by dispatching resources properly to the development teams. Traditionally, the project scheduling has been done with a manager's intuition or heuristic. We present a scheduling model with illustrative examples, stochastic search approach, and apply a variety of problems generated randomly to the approach. The results are analysed.

The area of informatization in small business industry consists of production automation. management automation, and network. This paper mainly deals with the management automation which uses management information systems. Functionally speaking, there are four broad categories such as manufacturing, marketing. human resource, and accounting. However, since most of small business industries emphasize more on the manufacturing and marketing, an integrated information system with these two core processes has been developed based on object-oriented methodology. The system, one of the important steps in the stage model this paper proposes, has not only simple and essential features ensuring easy implementation, but also friendly interface and good modularity based on the object-oriented paradigm.

One of the important applications in Enterprise Resource Planning(ERP) systems is the Manufacturing Resource Planning(MRPII) system using Bill of Material(BOM). The manufacturing resource planning determines the quantity and timing of the production or purchase of subassemblies and raw materials needed to support the Master Production Scheduling(MPS). The bill of material is the recipe, a list of the materials needed to make a product. This paper intends to suggest a component-based materials management system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based materials management systems designed with UML methodology, we analyzed the workflow and the document on materials management process from production planning to inventory management, and implemented a prototype of efficient materials management system, as a surrogate of existing material requirement planning(MRPI) system. To produce many other assemblies for a automobile part firm, component parts are assembled into subassemblies that are joined to assemble the finished product. Through the system suggested in this study, the level of inventory has cut down and the cost of inventory management has decreased. Also, the development method using UML makes the analysis and design phase to shorten in implementation period of MRPII system. The implementation of materials management system using CBD shows the ease of use in software reuse and the interoperability with corporate Internal information system. The result of applying object-oriented CBD technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology.

SMRT(Seoul Metropolitan Rapid Transit Corporation) changed PC-oriented office system to Smart-Phone oriented mobile office system(STnF: SMRT Talk & Flash), and provided smart phone to all staffs. STnF make it possible not only voice communication between staff, but also to input and inquiry all kind of information related to work(ex: Facility maintenance, Rolling Stock management, office management, Finance, human resource etc.) based on smart phone. STnF conquers the limitation of time and space. All staffs can commute to the site directly to reduce moving time and to share information between staffs, so SMRT improve speed and reliability of work by making a quick decision and action on the spot. After introduction of STnF, within 1 year, the equipment failure ratio fell to 47%. Mobile office system reduced and level-off the step of approval. so enhanced civil customer service. Quantification and scientific movement of work make it fast evolution and development. These business improvement make it possible to put more outstanding manpower on new business and R&D project, and this contributes to company's management effectiveness.

The prospects for growth of the nuclear power industry in Korea have improved remarkably as the demand for energy increases in stride with economic development. Meanwhile, as nuclear energy development is enhanced, nuclear technology has also improved evolutionarily and innovatively in the areas of reactor design and safety measures. As nuclear technology development in Korea advances, more human resources are required. Accordingly, the need for a well-managed program of human resource development (HRD) aimed at assuring needed capacities, skills, and knowledge and maintaining valuable human resources through education and training in various nuclear-related fields has been recognized. A well-defined and object-oriented human resource development and management (HRD&M) is to be developed in order to balance between the dynamics of supply and demand of the workforce in the nuclear industry. The HRD&M schemes include a broad base of disciplines, education, sciences, and technologies within a framework of national sustainable development goals, which are generally considered to include economics, environment, and social concerns. In this study, the projection methodology considering a variety of economic, social, and environmental factors was developed. Using the developed methodology, medium- and long-term nuclear human resources projections up to 2030 were conducted in compliance with the national nuclear technology development programmes and plans.

The stress experienced by employees on international deployment has serious implications for their physical and mental health as well as their work performance. This study aimed to investigate the impact of resource-oriented music listening on work-related stress among employees on international deployment. The study recruited 10 participants of varying ages and occupations who had worked abroad for at least three years and conducted five personalized resource-oriented music listening sessions along with interviews. The Global Assessment of Recent Stress Scale (GARS) and Job Stress Scale (JSS) were used to measure stress levels before and after the intervention. Results showed that participants' work-related stress and perceived stress were significantly reduced following the music therapy intervention. The study also found that "awareness of own's life situation" and "self-acceptance of here and now emotional challenges" were factors that reduced regulatory stress among employees on international deployment. This study highlights the potential of resource-oriented music listening as a useful tool for managing workplace stress and promoting the well-being of expatriate employees.

The article's purpose is to depict the experiences and cognition of Korean male workers on the relationship between work and family, in a conglomerate company. It examines the data of 11 interviews, especially focusing on the issue of participation in family lives. The cases consist of new comer employees, managerial officers, and executive personnel. According to the interviewee's report, Korean companies have drastically changed from a so called collectivistic culture to an individualisic one. In addition, the styles of their stories have changed drastically. New comers and managerial officers accentuate the importance of family in contrast to the attitudes of executive staff. These individuals also discuss the trend of increasing participation in domestic chores. However, the study does not illustrate a change in the younger generations' inner identities in relation to familial responsibility. Many of the interviewees' opinions taken from the study are almost similar in that these individuals do not encompass the lives of family in future plans. In conclusion, workers from large companiesin Korea maintain the attitude of focusing on official life one-sidedly.
