Shinbundang-line is new Metropolitan Railway which was invested by private capital and is under construction for opening in 2010. Now Shinbundang-line pursues various innovation, for example, an express train which uses long distance of each station, and an unmanned operation. And it may be independent of existing metropolitan railway system from a viewpoint of line and fare system. So according to the present plan, Shinbundang-line will be not able to get sufficient demand because of weak connection with existing lines and monotonous function of the line. And it may be difficult to deliver various innovation which Shinbundang-line prepares to passengers. Hereupon, in this paper, I propose 3 methods for increasing competitive power of Shinbundang-line railway. First, making Shinbundang-line a trunk railway line of southern metropolitan area was proposed in relation to northern and southern extension of it. In addition connection with bus and light rail was discussed. Second, multipurpose usage of Shinbundang-line was proposed as express train and conventional passenger train in that line in addition to simple metropolitan railway. Finally, an effective operation method which Shinbundang-line must have was proposed from unmanned driving and fare system side. These methods can improve Shinbundang-line and then it will solve traffic congestion of southern metropolitan area effectively.

This research aims to take a close look at the following topics; the ground elevation of playground, equipments of playground, and equipments around playground, and to propose the improvement measure for favorable educational environment. In consideration of the needs mentioned, the following improvement measure for playground can be suggested. First, the elevation of playground should be changed. According to Environment psychology, current playground elevation should be lowered 2 stair-long height from a classroom site. This kind of elevation change can remove unnecessary stairs, and reduces inconvenience incurred by stairs and edges, which results in considerable educational finance saving. Second, the incidental equipment within a playground needs to be improved. This fact is found out at the surveyed schools; school gathering is held at classrooms (through broadcasting) or a multi-purpose auditorium in place of a playground. The results of this study make us conclude that the most important issue to be considered in the processes of selection and investigation for school playground elevation, incidental equipments and others.

The purpose of this study was to discuss how traditional construction practices could be applied to school buildings. The spatial arrangement and constituents of Seoweon and Hyanggyo buildings were analyzed, and the spatial arrangement and ground plans of current schools were analyzed as well. As a result, it's found that how the characteristics of traditional architecture should be reflected in today's school design is one of critical matters that need an immediate attention. Based on the case study, there are some suggestions about the application of traditional construction techniques to school buildings: (1) The link between internal and external spaces should be stressed. The type of spatial configuration the could ensure nature accessibility is required. (2) The use of environment-friendly materials is recommended, and classrooms should be arranged in a way to let them function as multipurpose educational spaces. (3) It's not advisable to construct school buildings according to the sung-Confucianistic construction techniques of traditional educational institutions, but there should evidently be a change in tasteless school buildings, They should be built in small size and in consideration of harmony with nature and ecosystem, and boarding schools should be constructed in a more careful and discreet manner.

Manufacturing technology for the production of high value-added fine chemical products is emphasized and getting more attention as the diversified interests of customers and the demand of high quality products are getting bigger and bigger everyday. Thus, the development of advanced batch processes, which is the preferred and most appropriate way of producing these types of products, and the related technologies are becoming more important. Therefore, high-precision batch distillation is one of the important elements in the successful manufacturing of fine chemicals, and the importance of the process operation strategy with quality assurance cannot be overemphasized. Accordingly, proposing a process structure explanation and operation strategy of such processes including batch processes and batch distillation would be of great value. We investigate optimal operation strategy and production planning of multi-purpose plants consisting of batch processes and batch distillation for the manufacturing of fine chemical products. For the short-term scheduling of a sequential multi-purpose batch plant consisting of batch distillation under MPC and UIS policy, we proposed a MILP model based on a priori time slot allocation. Also, we consider that the waste product of being produced on batch distillation is recycled to the batch distillation unit for the saving of raw materials. The developed methodology will be especially useful for the design and optimal operations of multi-purpose and multiproduct plants that is suitable for fine chemical production.

This paper reviews researches related with the elderly caregiving, which hale published during the 1990s. After analyzingthe 29 articles in this field, the major findings are as follows: First, the advantageous position in life chances which is consisted of socioeconomic status and resources tends to reduce th burden for the elderly care. The higher in social status, the more resources older adults have, the more advantageous in controlling their relationship with their children and caregivers. Second, values based on familism is more associated with providing caregiving services for their parents than those of filial piety. Third, the tendency that daughter-in-law takes the role of the primary caregiver suggests a possibility of diminishing her enthusiasm, and finally comes to recognize her role as an enforced one, as time goes by. Fourth, cargiving burden affects the diverse aspects of caregiver's way of life. When the lower class elderly has dementia, caregiving stress and hassle have reached at their peak level. For meeting the needs of reducing the burden for the elderly care, this study suggests community- based approach for the elderly care. This approach attempts to share the caregiving burden with local community. To share the burden means that the boundaries of caregivers does not limit family members, but to expand community. This attempt includes a plan that establishes multipurpose community center which provides comprehensive services and care for the aged. The theoretical rationale of this approach are also discussed.
