Purpose: Prefabricated modular space such as a container construction has recently been interested unlike the conventional construction method, and their scale have expanded from small buildings such as cafes, houses and pensions to shopping centers, complex cultural spaces where shows and exhibitions are possible doing. In this way, the container is in the spotlight as an advantage such as mobility, flexibility, correspondence, economic efficiency, recyclability and so on. However, there are no specific guidelines and standard design methods in aspects of structural calculation, functional insulation and environmental configuration. Therefore, as the first step to resolve these problems, this study has focused on the field of environmental performance of container construction, presented appropriate guidelines and searched ways to improve performances. Method: For this study, seven types of the modular building were chosen and compared, and their energy performances have been analyzed using a proven simulation tool. Essential methodology and terminology were examined to estimate and judge their efficiency. Result: In conclusion, energy performances depend on specific configuration of combined unit spaces, and design guidelines cold be set up for promoting their use in the practical field.

Purpose: As emergency medical service fund is further expanded due to amendment of the law on emergency medical services in 2008, Korean government has prepared to intervene in a comprehensive manner to strengthen a trauma treatment system. As a result, it announced a master plan to establish a serious trauma treatment center in 16 areas across the nation. Therefore, this study has attempted to investigate the current status of the serious trauma treatment centers and suggest the goal and improvement plan of future serious trauma treatment centers. Methods: As of 2011, Korea operates 23 emergency cerebrovascular service centers, 23 emergency heart disease centers and 35 severe trauma treatment centers across the country. 12 emergency medical service centers have been chosen among the serious trauma treatment centers. Then, top six (6) centers chosen at Emergency Medical Institute Assessment 2011 by Ministry of Health and Welfare have been selected, and floor layout and spatial allocation by usage have been reviewed and analyzed. Results: Consequently, this study has investigated the spatial components, circulation layout and spatial allocation of a serious trauma treatment. For construction planning in consideration of the fundamental objectives and goal of emergency medical services, it is essential to allot spaces and select exact spatial components. It appears that it is necessary to design spaces for emergency medical services and come up with construction planning through appropriate spatial allocation.

The purpose of this study is to analyze the characteristics of the church architecture by Alvar Aalto. General features of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. The church would be the best example for understanding his architecture because he designed most of his churches in the prime of life. He established architectural types in his 30s through Viipuri public library and Saynatsalo town hall. He developed these types and applied them to his whole design. His type acts as a principle of configuration of his church architecture rather than a copy of form and shows the characteristics in the field of building layout, dynamic space and the effective use of light. Therefore, Aalto's church architecture can be recognized as the representative of Modern Finnish architecture in that they developed the meaning of their specific context including site, region and cultural tradition without losing the concept and technology of Modern architecture.

Recently, great improvements have been made in developing autonomous underwater vehicles (AUVs) using stateof- the-art technologies for various kinds of sophisticated underwater missions. To meet increasing demands posed on AUVs, a powerful on-board computer system and an accurate sensor system with an well-organized control system architecture are needed. In this paper, a new control system architecture is proposed for AUV, ORCA (Oceanic Reinforced Cruising Agent) which is being currently developed by Korea Research Institute of Ships and Ocean Engineering (KRISO). The proposed architecture uses a hybrid architecture that combines a hierarchical architecture and a behavior based control architecture with an evaluator for coordinating between the architectures. This paper also proposed a sensor fusion structure based on the definition of 4 categories of sensors called grouping and 5-step data processing procedure. The development of the AUV, ORCA involving the system architecture, vehicle layout, and hardware configuration of on-board system are described.

Component-based development approach is used in modern software system development projects that are very complex and large-scale. Technical components are more effective rather than business components in software development. However, on the Microsoft .net environment, the technical component-based development issues are not adopted. Moreover, software architecture on the .net environment is not studied yet because the development platform is recently used in the development of enterprise-level system. This paper proposes a technical component-based software architecture on .net environment. Seven technical components - configuration, data access, exception, file I/O, log, message, and paging - are contained in the architecture. The proposed architecture enables developers to reduce development time and to concentrate business logic rather than architectural issues. To verify the proposed architecture and the components, a partner management system is developed based on the architecture.

This study aims to analyze the design concepts of Libeskind's Jewish museums through their comparisons for figuring out his design intentions and characteristics in the realization process. Libeskind's realized four Jewish museums are chosen for this study. For more concrete study, their extracting and application process are also reviewed. The comparison of his museum designs can be good examples in that they show different design approaches on the same architectural type, Jewish museum, to tell their something in common from differences. He could realize his architectural thoughts and configuration methods made by experimental drawings for the first time as real buildings through a series of Jewish museum projects. The commonness of Libeskind's Jewish museums lie on their sharing design concept of Jewish 'history and memory', especially Holocaust, and realized as in contrast to surroundings and 'labyrinth' of spatial configuration to maximize spectator's experiences. As Libeskind regards museum architecture as a carrier of 'time and place', he tried to reflect surrounding context including places, cities, persons and events about museum programs. As a result, unprecedented museums which are not related to traditional museum systems about circulation and spatial configuration are suggested for users to experience Jewish life and history through architecture.

The results of a series of finite element (FE) simulations and experimental studies are used to develop strength and stiffness models that predict the failure capacity and response characteristics of unstiffened extended endplate connections with circular and rectangular bolt configurations associated with deep girders. The proposed stiffness models are composed of multi-linear springs which model the overall extended endplate/column flange system deformation and strength of key-components. Comparison of model predictions with FE and experimental results available in the literature show that the proposed models accurately predict the strength and the response of extended endplate/column system with circular and rectangular bolt configurations. The effect of the bolt configuration (circular and rectangular) on the prying phenomenon encountered in the unstiffened extended endplate/column system was investigated. Based on FE results, extended endplate with circular bolt configuration has a more ductile behavior and exhibits higher total prying forces. The proposed models can be used to design connections that cover all possible failure modes for extended endplate with circular bolt configuration. This study provides guidelines for engineers to account for the additional forces induced in the tension bolts and for the maximum rotational capacity demand in the connection which are required for seismic analysis and design.
