The current paper is to review the need to considering cultural and educational aspects rather than technical approaches for the maritime safety. General and rather simple views on culture and education are provided as well as the state-of-the-art of the methodologies on ship safety assessment. Conclusions such as the national role and contributions to the international bodies and the third worlds are drawn in addition to the importance of cultural and educational factors to enhance the safety of ships.

An intelligent grid computing architecture is proposed and developed for transient stability constrained total transfer capability evaluation of future smart grid. In the proposed intelligent grid computing architecture, a model of generalized compute nodes with 'able person should do more work' feature is presented and implemented to make full use of each node. A timeout handling strategy called conditional resource preemption is designed to improve the whole system computing performance further. The architecture can intelligently and effectively integrate heterogeneous distributed computing resources around Intranet/Internet and implement the dynamic load balancing. Furthermore, the robustness of the architecture is analyzed and developed as well. The case studies have been carried out on the IEEE New England 39-bus system and a real-sized Chinese power system, and results demonstrate the practicability and effectiveness of the intelligent grid computing architecture.

The decrease in population of school age is one of major influencing factor of transformative educational environment. After the nineteen eighties, the population of South Korea has increased step by step, but the population of school age has been decreasing rapidly by low birth rate. As a result, closed school by merger and abolition of small school occurred all over the country. The closed school needed effective function as center of local community. Consequently the purpose of this study is to provide basic data for effective policy making of closed school by comparative analysis of educational environment such as number of students, schools, students per class, status of usage of closed school of the east area and the west area divided by The Tae Baek Mountains in the Gangwon-do, which has the least students in the nationwide. The results of this study are summarized as follows: 1) Gangwon-do has high decreasing rate of population, schools and students compared with other provinces. However it has significantly low number of students per class. 2) The number of students, schools of the west area in Gangwon-do outnumbers that of the east area. However the number of students per class of the east area in Gangwon-do lesser than that of the west area.

Purpose: The characteristics of site plan of dentistry through examining the schools of dentistry and dental hospitals in Korea and comparison between them are necessary for the development of planning of the dental healthcare system. This study has been started to provide basic information for the planning of education and hospital architecture in dentistry. Methods: Literature review of space analysis and investigation on current status of dentistry in Korea have been conducted. The site plans of eleven schools of dentistry and dental hospitals have been analyzed with S3 axial analyzer in space syntax. Results: The result of this study can be summarized in four points. The first one is that the site plan of school of dentistry and dental hospital is influenced on the location of main campus in the city. The second one is that the types of relationship between dentistry and main campus are diverse from school and hospital in the main campus to independent dental campus in the city center. The third one is that the integration, connectivity and ERAM(3) of dental hospital are greater than school of dentistry and it means that dental hospital is located in easy access area compared with school of dentistry. The fourth one is that school of dentistry roles the connection space between main campus and dental hospital. Implications: It is necessary to analyze the site plan and arrangement of school of dentistry and dental hospital in the campus to develop the dental healthcare system in the city.

Hybrid coupled shear walls in tall buildings are known as efficient structural systems to provide lateral resistance to wind and seismic loads. Multiple hybrid coupled shear walls throughout a tall building should be joined to provide additional coupling action to resist overturning moments caused by the lateral loading. This can be done using a coupling beam which connects two shear walls. In this study, experimental studies on the hybrid coupled shear wall were carried out. The main test variables were the ratios of coupling beam strength to connection strength. Finally, this paper provides background for rational design guidelines that include a design model to behave efficiently hybrid coupled shear walls.

Most offshore structures including offshore wind turbines, ships, etc. suffer from the impulsive pressure loads due to slamming phenomena in rough waves. The effects of elasticity & plasticity on such slamming loads are investigated through wet free drop test results of several steel unstiffened flat bottom bodies in the rectangular water tank. Also, their cumulative deformations by consecutively repetitive free drops from 1000 mm to 2000 mm in height are measured.
