The urban form of Korean cities significantly changed in the late Chosun dynasty. The influence of commercial development was the main cause of these changes. Commerce became a important function of existing cities, and the new type of commercial towns emerged at the important spots of traffic routes. In both cases streets became dominant element of urban form. Mainly commercial buildings aggregated along the streets, and to obtain higher land use intensity shape of lots became narrow and deep. Koyang(高陽) shows the most significant example of this new type of lot and lot pattern. Approximately 30 narrow and deep type of lots lined on each side of street forming about 390 meters long linear commercial town. Similar examples were found at the outside of south gate of Suwon(水原), Nuwon(樓院), and Pangyo(板橋).

In contemporary architecture, a tendency of architectural expressions is very various aspects, therefore this study is searched about how to express the works of Richard Meier, the background of his growth, his architectural thoughts and etc. Especially the meanings of 'white architecture' have contained, which was presented on the relationships of nature, light, purity and completeness. Lucid and complex, refined yet robust, rational and poetic, richard Meier's architecture has a timeless quality. for over three decades, he has steered an unwavering course through the shoals and cross currents of architectural fashion, creating a secession of serene white houses museums, public and commercial buildings. from Getty Center, his architectural genius came into the world agaiv. With has architectures, this study tries to read the streams of direction on Richard Meier and contemporary architecture.

Recently, Architecture Frameworks are used to develop Information Management System (IMS). This paper describes an operational architecture development method for railway system safety assessment. using DoDAF (Department of Defense Architecture framework). The need of IMS is increasing to perform safety assessment task effectively and efficiently as safety-critical system like railway System. It is necessary that operational architecture based IMS requirements generated fir safety assessment. ARP(Aerospace Recommended Practice)4761 are referred to develop safety assessment operational architecture applicable to railway system. Firstly, schema and template was developed to perform the operational architecture development process using a commercial CASysE(Computer-Aided Systems engineering) tool, CORE. Not only the operational architecture allows building flexible IMS, but also helps business process solving.

This paper discusses a new formulation for the failure strain in the average stress triaxiaility domain for a low-temperature high-strength steel (EH36). The new formula available at a low average stress triaxiality zone is proposed based on the comparison of two results from tensile tests of flat type specimens and their numerical simulations. In order to confirm the validity of the failure strain formulation, a user-subroutine was developed using Abaqus/Explicit, which is known to be one of the most popular commercial finite element analysis codes. Numerical fracture simulations with the user-subroutine were conducted for all the tensile tests. A comparison of the engineering stress-strain curves and engineering failure strain obtained from the numerical simulation with the user-subroutine for the tensile tests revealed that the newly developed user-subroutine effectively predicts the initiation of failure.

In the modern city in which the high-density and complex land use is needed, high-rise residential-commercial buildings appeared as a scheme to arrange a metropolitan residence with multiple high-techs and to induce activation of the city with leading the settled population to flow into the city. And the need of the times is to actively apply the eco-friendly notion to the architecture. In this study, the works of Ken Yeang who is regarded as an eco-friendly architect to make high-rise residential-commercial buildings ecological should be focused on with analyses of eco-friendly characteristics in inside, intersection between inside and outside, and outside of his works. The result o the study would be the suggestion to design eco-friendly high-rise buildings which make the city rise in quality.

Since late 1960s, we have had the discourse about the way of succession of korean traditional architectural heritage. Through 60s and 70s, the formal mimesis and transformation was pretty much dominated in domestic design currents. After 80s, we could see a kind of different ways of design to deal with traditions in architectural practices. These methodology can be summarized as spatiality, abstraction and diversity. These discourses acted as bases for aesthetic and formal stream which might be needed to present the formal possibilities for various commercial needs. Especially, the interior design field utilized those ideas in order to show korean identity for the commercial needs such as korean restaurant, korean bar, or korean costume shop. Interior designers positively adapted the ideas from architectural discourse and created their own vocabulary after 90s. Before 90s, interior designers did very representational mimesis to express korean identity designing commercial facilities. However from mid 90s they could establish new tendencies in expressing korean traditional moods. These tendencies are a focus on spatial relationship, abstraction and materiality, utilization of traditional objects and lighting method.

The recent completions of free-form spatial structures provide us a very attractive form. To realize such an extraordinary shape, it is absolutely necessary that the connector systems have to be investigated the characteristics of the systems and analyzed with a practicable method. In this context, this research consists of not only literature research but also numerical analysis with selected connector systems, which was adopted in real free-form spatial structures. For numerical analysis, especially, finite element analysis (FEA) is performed with a various test parameter using a commercial program ANSYS. Consequently, the general characteristics of node connectors the moment-rotation-curves are presented by considering a large deformation effect as well as a multi-linear material properties.

Townscape design is now considered to be the most important part in city management as a means to improve the life quality of its dwellers. Therefore, the recognition of local autonomous entities and local residents on townscape has been greatly changed. As a part of this effort, the plan to improve the townscape of the central rotary district in Geochang-eup has been examined in multilateral ways. In this plan, first, improvement for proper buildings was studied. Second, betterment for street furniture around the central rotary was considered. Third, making a landscape square around it was also investigated. Based on those considerations, this article intends to suggest directions for improving the commercial buildings of the central rotary district which has the greatest symbolicity in Geochang-eup. To achieve the goal, this paper conducted a survey to the dwellers beforehand in order to investigate their recognition on creating townscape for the central rotary district and collected their opinions on it. According to the result, among the elements of townscape in the shopping district around the rotary, the externals of the buildings such as signboards, color, and shape and the pleasantness part like the maintenance of telegraph poles occupied the highest portion on the street. And It is proposed 4 Alternative plans for the improvement of commercial building design in the central rotary district of geochang-eup.

Recently, the roof garden of the large commercial facilities has been changed as a complex cultural space follow the users' diverse needs. It is focused on large commercial facilities on Seoul and Gyeonggi area but large commercial facilities of the province still has not been able to respond to the needs of users. Thus, the present condition of roof gardens was compared space components with physical environmental factors in Seoul, Gyeonggi and Daejeon, Chungcheong. Throughout the comparison, roof gardens in Daejeon and Chungcheong area were focused on finding ways to improve As a result, roof gardens in Seoul and Gyeonggi area were applied to a variety of factors in space components experience, learning, performance, exhibition and etc. It is composed to take place of various acts in the roof garden. On the other hand, roof gardens in Daejeon and Chungcheong were not applied a variety space components by comparing Seoul and Gyeonggi area. Physical environmental factors also were insufficient by comparing Seoul and Gyeonggi area the landscape, awning facilities, amenities for handicapped. As described above, space components and physical environmental factors in Daejeon and Chungcheong area roof gardens were insufficient. To perform the role of the roof garden changing as a complex cultural space and to confront to the users' needs space component such as learning, performance, exhibition should be considered during planning. And physical environmental factors supportable space components should be considered together.
