In this study, the various financial management systems practiced by modem dual-income families were assessed by in-depth interviews with 6 people, 3 practicing integrated financial management and 3 practicing individual financial management. The results indicated significant differences between the two financial management methods regarding family structure, individual values, and family finances. Families that practiced individual financial management consisted of weekend couples without children who showed an individual-centered value tendency and seemed to take a positive attitude towards their future economic situation due to possession of their on stabilized financial assets. Based on these results, we can expect more families to adopt methods of individual financial management and show a wider variety in their financial planning tools which will require adequate and efficient countermeasures and strategies suitable for each financial management practice.

The purpose of this parer is to provide a survey of the state of the art of routing methods in store-and-forward computer networks. The survey is carried out in line with a new taxonomy： heuristic methods, user-optimization methods, and system-optimization methods. This taxonomy on routing algorithms is based on two viewpoints： the level of optimization and the relative difficulty for the implementation in real computer networks. Some actual methods implemented in real computer networks are surveyed as well as the theoretical studies in the literature. This paper concludes with some points in need of further researches.

I propose new combined randomized methods for global optimization problems. These methods are based on the Nested Partitions(NP) method, a useful method for simulation optimization which guarantees global optimal solution but has several shortcomings. To overcome these shortcomings I hired various statistical selection methods and combined with NP method. I first explain the NP method and statistical selection method. And after that I present a detail description of proposed new combined methods and show the results of an application. As well as, I show how these combined methods can be considered in case of computing budget limit problem.

The employment of risk management theory in Urban Disaster Management System (UDMS) has become an important trend in recent years. The viewpoint of risk management is mainly a comprehensive risk assessment of various internal and external factors, and a subsequent handling of risks. Through continuous and systematic accumulation and analysis of risk information, disaster prevention and rescue system is established. Taking risk management theory as the foundation, Organization for Economic Cooperation and Development (OECD) has developed a series of UDMS in the mega-cities all over the world. With this system as a common platform, OECD cooperates with different cities to develop disaster prevention and rescue system consisting of vulnerability assessment methods, risk assessment and countermeasures. The paper refers to the urban disaster vulnerability assessment and risk management of OECD and the mega-cities of different advanced and developed countries in the world, and then constructs a preliminarily drafted structure for the vulnerability assessment methods and risk management mechanism in the metropolitan districts of Taiwan.

The creation of knowledge is a major concern for knowledge management practice. In particular, effective knowledge creation is one of the critical success factor in SI(System Integration) industry. This paper designs a framework of effective knowledge creation methods for organizations in SI industry. First, we give a comprehensive survey on knowledge creation and discovery methods. And the structure of SI knowledge has been analysed. Also, characteristics of knowledge management processes of SI industry have been surveyed and analysed. A framework for effective knowledge creation of SI organization has been discussed based on the characteristics of SI knowledge and knowledge management processes. Organizational issues and theoretical issues of the methods have been discussed. Future research will be needed to expand the current framework and to examine the effectiveness of the proposed framework.

The use of the gas turbine for power supply is increasing recently. Accordingly, the operation and maintenance cost of the gas turbine is gradually increasing and the various efforts to cut the cost are needed. For an operation and maintenance cost saving of the gas turbine, reductions of the new purchasing charge and the reproduction repair cost of the hot gas parts are required through more effective operation and life management methods for the hot gas parts. The hot gas parts are the main parts of the gas turbine and they are replaced with the periodic. In this research, efficient operation and life management methods for the hot gas parts were presented with the cases. The methods were analyzed and verified based on real data and the cases for improving a lifetime were utilized in the field.

Today, most companies are needed to become interested on e-Biz and information management system. Especially, Data classification format system was very important for application to effective and efficiency management decision support. They should include main entry which consists of department, employee's name, title, publication date. Now, each company is using eleven different methods on data classification format system. In this paper finding result was as follows, in other words, general management document case using the nine date classification methods and special report management document ca se using the twodata classification methods. The aim of this study is to investigate problems that the present data classification format system has and some concerns that should be taken into account in case of the modification of the data classification system and change into a new one. This study is based on the survey in that the company managergave to 35 companies throughout the nation. As a result, the survey indicates that the crucial concerns of the participating managers are ineffective management information source and the duplication of data classification systems. This paper is the transcendental study the introduction of data classification format systems to business companies in Korea. This paper provided the fundamental data for the effective business process reengineering in business activity for management information.

Purpose: The purpose of this paper proposes an effective and systematic methods of risk management in product development project. Methods: This paper first discusses what risk factors be considered during product development period and then presented a model for preventive risk management. For that, this paper proposes how to evaluate the risk factors and risk events, and how to select prevention action for managing risk factors effectively. For this process, this paper uses well-known quality tools such as House of Quality (HOQ) and Failure Mode and Effects Criticality Analysis (FMECA) methods. Results: There is an inherent need for the development of robust risk management framework in order for product development projects to be successful. The identification and quantification of risk factors, risk events, and prevention actions can have significant effects on the success of a product development projects. Project managers can implement the proposed model to improve project success. Conclusion: The findings showed that this method would be effective for project managements in dealing with risk management issues in product development projects. This method presented would be an one of good guidelines for practitioners in the industry.

국내 건설산업의 효율성 제고를 목적으로 1996년 12월 건설산업기본법의 제정과 함께 건설사업관리(Construction Management, CM) 제도가 도입되었지만, 16년이 지난 현재 발주청이 공공건설공사 수행 시 건설사업관리 방식을 선정하기 위한 명확한 가이드라인이나 지침의 부재 등으로 인하여 발주청이 건설사업관리 방식의 적용여부를 자체적으로 판단하기 매우 어려운 실정이다. 이에 따라 본 논문에서는 이론적 고찰 및 설문배포, AHP분석을 통하여 공공건설공사에서의 건설사업관리 방식 적용을 위한 검토기준을 마련하였으며, 실제 지방국토관리청에 등록되어 있는 발주공사를 바탕으로 사례적용 Simulation을 수행하여 발주청이 건설사업관리를 위탁 시행하기 위해 필요한 적정성 검토의 선정 기준을 수립하였다. 국내에서는 향후 건설사업관리에 대한 수요가 공공 부문이나 민간부문에서 점점 더 확대 될 것으로 기대된다. 그러나 현재 상태의 건설사업관리 제도 하에서는 건설사업관리 방식을 적용한 건설 사업이 본격적으로 활성화 되기는 어려울 것으로 판단되고 있다. 따라서 국내에서도 선진국 수준의 건설사업관리 제도가 활성화 되도록 적극적인 노력이 필요하다고 할 수 있으며, 발주기관에서는 건설사업관리 제도의 활성화를 위하여 발주방식 선정 시 건설사업관리를 위탁 시행하기 위한 건설공사의 적정성 검토의 자료로 본 연구 결과를 유용하게 활용할 수 있을 것으로 기대된다.
