Conventional apartment building projects have favored wall slab structure for the ease of construction and economic viability. However, wall slab structure, consisting of bearing walls, makes remodeling a difficult challenge. In addition, as the amendment to the Building Act in November, 2005 incentivized easy-to-remodel Rahmen structure design for apartment building in terms of floor area ratio and the number of stories, were are seeing more use of PC construct method in apartment building projects gradually. However, PC construction method requires complex connections between beams and columns, making it difficult to install and remove formwork. Furthermore, it is not possible to reuse forms after removal, generating lots of construction wastes, and it is necessary to install new forms again when the size of connection changes in line with modification of column cross-section. Researchers in Korea and elsewhere in the world have focused on structural performance of connection in PC construction method, with little attention to alternative approaches to improving connection forms for PC construction method. Accordingly, this research aims to study an approach to improving connection forms for PC construction method.

The purpose of this study was to investigate the effects of early storybook reading intervention participation on the first graders' language abilities in low income families. The subjects consisted of 148 first graders and their primary caregivers. The intervention group was composed of 100 first graders who participated in the early storybook reading intervention program in childcare or kindergarten. The comparison group comprised 48 first graders from equivalent social and economic backgrounds, who did not participate in the program. The language abilities of the children were tested and questionnaires regarding the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors were completed by the children's primary caregivers. The data were analyzed by means of structural equation modeling. The results indicated that early intervention participation was directly associated with children's higher language abilities in first grade and indirectly influenced the children's language abilities through the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors.

By the continued island-mainland bridging works, increased consumer demand for seashore regions and fundamental improvement of accessibility to metropolitan areas, rural service industries in the island areas has been rapidly developed in the past decades, and also, their functions differentiated geographically. In most island areas, catering and accommodation sectors have been expanded, while traditional trading sector decreasing. And the dominant power of public sectors has been increased but private ones decreased. So, the overall development trends of service industries in island areas would be considered as unhealthy for rural economic sustainability. As a tentative solution, it may be proposed that through the functional specialization/differentiation and efficient linking/networking of rural service industries with multifunctionality of countryside capitals, their spatial cohesion would be strengthened.

National major facilities have been rigorously investigated using regular safety inspections and precision safety diagnosis since the Special Law for Facilities Safety Management was made in 1995. However, the process of safety inspection and precision safety diagnosis could be doubted due to intervention of facility owner for safety level evaluation, competition to obtain low price order, and low technical skills of inspection companies. Although the management processes for evaluating the inspection companies were used for several years, the process should continue to improve in the safety inspection field. This study analyzed the recent evaluation system and the ratios of insufficient inspection. Estimation of national loss expenses to the insufficient safety inspection was investigated to recognize the necessity for the improvement of facility inspection process and evaluation system.

This study aims at examining the structural and managemental problems of the existing fishways which affect the migrations of fishes, and at suggesting alternatives to improve the fishways' efficiency. The study focuses on the fishways constructed in the diversion weirs in the lower reaches of 41 rivers(2 national rivers and 39 rural rivers) in the eastern coast of Korea. Most of water-using facilities in Korean rivers are diversion weirs, and fishways are established as subsidiary facilities of most of the weirs. Among the 58 or so fishways examined in this study, only a few are doing their proper function, and most of them need improvement. This study aims at strengthening those fishways function and increasing their economic efficiency and migration efficiency. Based on the results of this study, the followings are suggested. In case the fishway sticks out downstream from the apron, a subsidiary fishway diverging from the main is suggested to attract fish. The entrance to the subsidiary should head below the raised part of the apron and a pool should be constructed in the connecting part with the main. To attract fish and let the upstream migrators rest for a while, an entrance pool should be constructed in the fishway. Most of the examined fishways have low side walls, which allow the upstreamers to jump out of the fishway. Those side walls are suggested to be raised above the jumping height of target fishes. The exit parts of most fishways are too shallow, or have no grass to protect the fish from the birds. Protective facilities are suggested to keep the birds from entering the fishway. By the time Ice-harbor type and Vertical-slot type fishways are scientifically proved to be defective, the fishway should not diverge from the standard design.
