This study started from my concern over maintenance and renewal of existing buildings and other seriously damaged Modern Architecture under the urban development. Above all, we must face up to reality of an increasing need of renovation of old buildings that are in its physical, social, and economical decrepitude. Currently, 25% of total buildings come under renovation period within 20 years, which means that we do not have enough time to decide the destiny of old buildings. In the city, there has been endless controversy over conversation and development. Recently the Cultural property Registration System made it possible a positive usage of non-designated cultural property with historical value. This very useful system renewed our perception on Modern Architecture as cultural property and also triggered peoples' interest in recreating new value beyond economical one. So we really need a balanced view that can bring into both growth of contemporary city and renewal use of Modern Architecture. Here, in this study I tried to solve that problem with Conversion Design and define what a realistic design way for them is. To get more reasonable result, I chose a factor analysis for 20 conversion projects in Japanese Modern Architecture. Conversion Design is a proper way to restore the identity of old buildings and the most effective way to sustainable use of Modern Architecture.

본 논문은 소프트웨어 아키텍처의 설계를 위한 방법론을 제안한다. 논문의 제안하는 아이디어는 시스템에 존재하는 액터(actor)나 모듈, 통신요소 간의 인터페이스를 식별하면, 이 인터페이스에 연결된 모듈을 단계적으로 탐색해 나가는 방식을 활용한다. 그리고 설계범위의 인터페이스와 모듈을 점차 확장해 나감으로써 아키텍처의 설계가 완료될 때까지 설계를 점진적으로 진행해 간다. 이 방법은 기본적인 아키텍처 설계의 접근을 인터페이스로부터 출발하여, 이 인터페이스의 입력을 기다리는 모듈, 그리고 다시 이 모듈로부터 출력 인터페이스를 확인하는 방법을 통해, 설계의 원인과 결과가 서로 연관되게 함으로써 자연스러운 설계를 유도한다고 할 수 있다. 또한, 제안 방법은 아키텍처 설계에 필요한 5개의 아키텍처 뷰를 정의하고, 설계과정에서 아키텍처 패턴의 활용하도록 하고 있다. 특히, 이 방법은 아키텍처 설계를 처음 습득하는 설계자들에게 설계방법에 대한 구체적인 이해를 도모한다는 장점을 제공한다.

Traditional text-based system engineering, which has been used in the design and application of passive residual heat removal system (PRHRS) for lead-cooled fast reactors, is prone to several problems such as low development efficiency, long iteration cycles, and model ambiguity. This study aims to effectively address the abovementioned problems by adopting a model-based system engineering (MBSE) method, which has been preliminarily applied to meet the design requirements of a PRHRS. The design process has been implemented based on the preliminary design of the system architecture and consists of three stages: top-level requirement analysis, functional requirements analysis, and design requirements synthesis. The results of the top-level requirements analysis and the corresponding use case diagram can determine the requirements, top-level use cases, and scenario flow of the system. During the functional requirements analysis, the sequence, activity, and state machine diagrams are used to develop the system function model and provide early confirmation. By comparing these sequence diagrams, the requirements for omissions and inconsistencies can be effectively checked. In the design requirements synthesis stage, the Analytic Hierarchy Process is used to conduct preliminary trade-off calculations on the system architecture, after which a white box model is established during the system architecture design. Through these two steps, the analysis and design of the system architecture are ultimately achieved. The resulting system architecture ensures the consistency of the design requirements. Ultimately, a functional hazard analysis was conducted for a specific incident to validate case requirements and further refine the system architecture. Future research can further reduce the design risk, improve the design efficiency, and provide a practical reference for the design and optimization of PRHRS in digital lead-cooled fast reactors.

In this study, the concept of environmental-friendly architecture, where environment is importantly regarded as a design concept in modern architecture and the meaning of boundary are examined, To apply properly design methodologies along with the importance of environment, the concept of environmental-friendly architecture should be first correctly established. And as the recent rapid development of technologies provides new possibilities for environmentally-friendly architecture, it is needed to have a new boundary concept and the interpretation of the meaning of boundary differentiated from the one of existing architecture. Recently the meaning of boundary is expanding its range to the relations with its neighboring environment beyond the relations with in and out of a space and has also the role as a medium for exchange and communication instead of breaking-off. Therefore, the boundary of environmental-friendly architecture alongside physical boundary is extended to the area for communication. Here, a basic boundary of architecture is maintained, but its meaning and expressions get natural shapes. The study deals with the analysis of the concept of environmental-friendly architecture and its changes from the perspective of times, environment and social backgrounds and seeks its appropriateness centered on environmental-friendly architecture Since 1980s when the issues of human and environment were raised in earnest.

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.

Development of the system that has required performance is the most important figure and that is the key of project succeed. In order to perform that, systems engineering has come to the fore as a solution. In each step of system engineering process, particularly, requirement analysis and derivation, logical solution, architecture design step are known to affect many of the function and efficiency. Of these, this paper focus on architecture design. We introduce methodology for physical architecture design by applying DSM(Design Structure Matrix) methodology which is based on result of logical solution from MBSE methodology.

This study aims to analyze the typological characteristics of Alvar Aalto's library design. The unique characteristics of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. Besides this, Aalto's typological approach in design made his color. The library might be the best example for understanding his design approach in that he showed 3 main features of type; wholeness, self-control and transformation. He established architectural types in his 30s through Viipuri public library and developed so-called fan type library plan. Aalto's library type is not a simple copy of exterior and interior form. It acts as a principle of configuration of his library architecture and applied to the building. Therefore, Aalto's library architecture can be recognized as the results of typological design approach in that it shows the transformation of type in according to factors including site, size, region and cultural tradition. In conclusion, Aalto's libraries reveal the typological characteristics in the field of building layout, dynamic space and the effective use of light.

In this paper we present a new-generation sensor network processor which is not optimized in circuit level, but in system architecture level. The new design build on a conventional processor architecture, improving the design by focusing on application oriented specification, ISA, and micro-architectural optimization that reduce overall design size and advance energy-per-instruction. The design employs harvard architecture, 8-bit data paths, and an compact 19 bit wide RISC ISA. The design also features a unique interrupt handler which offloads periodical monitoring jobs from the main part of CPU. Our most efficient design is capable of running at 300 KHz (0.3 MIPS) while consuming only about few pJ/instruction.

Hospital Architectures in Korea are continuously erected to old-fashioned design, such as a large self-sufficient, but cost-inefficient hospital, in spite of rapidly changing social and healthcare environment. However, changes are slowly coming from inside of itself. This paper analyzed block plans of 7 best Korean hospitals which constructed in recent 20 years in aspects of the purpose of erection, departmental composition, areal composition, mass design and functional zoning of block plans and then, presented the directions of new design trends of hospital architecture in Korea. It is anticipated that hospital architecture will change immensely in the enlarging process of these minor changes.
