While economic incentives have led to migration, the failure to adapt to a new city and to ease the financial burden to support families have raised migrants' intention to return to their hometowns. Using the 2016 China Migrants Dynamic Survey, this study investigates determinants of migrants' intention to return. Migration at a young age, which is associated with lower barriers to the new culture, and intraprovince migration requiring less effort to adapt to the new city, were associated with lower intention to return. Also, migrants with less burden to support a family tend to have a higher intention to return to rural hometowns. Specifically, migrants with children over 18 years old and fewer family members are likely to return to their hometowns. To revitalize rural economy and reduce the rural-urban disparity, a policy to support migrants with high intention to return will be needed.

The growth-share matrix is a portfolio planning tool developed by the Boston Consulting Group (BCG) to assist competitive positioning in the international market including those in the construction industry. This matrix is helpful in balancing the firm's cash-flow, and it can suggest strategic directions for each business unit. However, its effectiveness and applicability have long been debated in the academic field due to the complex and unique industrial context of construction. To solve the dispute, this research clarifies the applicability of theories underlying the growth-share matrix to the construction industry. Empirical research based on actual financial data of Korean construction firms is adopted for the statistical analysis including one-way analysis of variance and correlation analysis. The results of this research show that empirical findings on the relationship between performance variables. In this context, this research can provide important insights on the concept of portfolio management in the construction industry.

In planning an assembly system, choosing the proper assembly sequence is one of the most important decisions because it significantly affects the costs associated with the assembly process. This paper deals with the selection of assembly sequences in flexible assembly systems. The selection criterion is the minimization of makespan to complete all assembly products. This problem is formulated as a "modified FAS scheduling problem" (MFASSP) and its scheduling procedure is described. The experimental results show that the procedure is very efficient for both quality of solution and computation time.

현재 은행들은 종합금융서비스업(Total Financial Solution)인 금융그룹화 추진에 비 은행 사업 분야를 보완하여 금융 업무 대형화를 강화하고 있다. 이에 따라 대형화된 은행권에서는 계열사 간 커뮤니케이션 부재를 해결하고, 각기 다른 기업문화를 통합 할 수 있는 조직 내 커뮤니케이션 매체로 위성영상방송을 찾게 된다. 본 논문에서는 대형화된 은행 내 조직 커뮤니케이션 매체로서의 위성영상방송이 조직에 어떠한 효과를 미치는지 알아보았다.

The purpose of this paper is to present a procedure for feasibility analysis of new hospitals. The major steps of the procedure proposed consists of determination of location for a new hospital, analysis of the community served, facilities planning, estimation of capital requirements and financial analysis. Technical details of the necessary analyses are covered by providing relevant information most of which is readily available in Korea. The procedure proposed in this paper can be applied not only for the case of the general hospital but also for the case of the clinic.

Due to a rapidly aging society, the future Korea mortality rate is important for planning national financial strategies and social security policies. Old age mortality statistics are very limited in their ability to project a future mortality rate; therefore, it is essential to accurately estimate the old age mortality rate. In this paper, we show that the CK model with a Relational model as a base model provides accurate estimates of old age mortality rates.

Recently, electric industry confront a strategical change and high competiveness environment in the course of deregulation. Especially, rapid growth in electricity demand, financial need for new power plant construction, and environmental problems have led to search for more efficient energy production and energy conservation technologies in Korea. Due to the potential energy and cost savings, DSM(Demand-Side Management) plays and important role in the electric resource planning. In this paper, we suggest DSM potential evaluation procedures and algorithm. Also, we present screening analysis methods for DSM potential evaluation.

Case-Based Reasoning(CBR) offers a new approach for developing knowledge based systems. In case-based approach the problem solving experience of the domain expert is encoded in the form of cases. CBR has successfully been applied to many kinds of problems such as design, planning, diagnosis and forecasting. In this paper, CBR was applied for forecasting default risk. The applied result was successful in spite of the small casebase. Generally, CBR requires large casebase. So, if the number of data was large, the result was better. But in this paper, what financial variable was more forecastable was not tested. Next, this should be tested.

While sustainability is seen in terms of social, economic and environmental dimensions, securing longterm financial costs and planning long-term strategic perspective among policy-makers are needed to maintain a healthcare system sustainability. Thus, the networking and cooperation between policy makers and health care workers should be tightened and strengthened in order to keep and enhance the healthcare system sustainability.

This paper investigates the time-inconsistent agent's optimal consumption and investment problem under inflation risk. The agents' discount factor is governed by hyperbolic discounting, which has a random time to change. We impose the inflation risk which plays a crucial role in long-term financial planning. We derive the semi-analytic solution to the problem of sophisticated agents when the time horizon is finite.
