Jeju Special Self-Governing Province has implemented a self-governing environmental impact assessment system (Jeju-EIAS) in recognition of its autonomy. In this study, the institutional features of Jeju-EIAS were examined by analyzing the development projects whose consultation under Jeju-EIAS were completed from 1994 to 2019. The consultation procedure of Jeju-EIAS, such as the actual operation of Review Committee for Environmental Impact Assessment (EIA), the consent of the provincial council, and the regular follow-up activities for the implementation of EIA consultations, has been implemented differently from those of other metropolitan cities and provinces. Under Jeju-EIAS, types of development projects subject to consultation on EIA also take into account local conditions, and include the construction of aquarium basin and building. In addition, provisions concerning the scale of development projects is strengthened above the Korean Environmental Impact Assessment Act (EIA Act).

This paper researches a lightweight composite structure referred to as the Profiled Steel Sheeting Dry Board (PSSDB). It is fundamentally produced by connecting a Profiled Steel Sheeting to Dry Board using mechanical screws. It is mainly employed as floor panels. However, almost all studies have focused on researching the one-way structural performance. Therefore, this study focuses on the bending behaviour of the two-way PSSDB floor system using both of Finite Element (FE) and Experimental analysis. Four panels were used in the experimental tests, and a mild steel plate has been applied at the bottom for two panels. For the FE process, models were created using ABAQUS software. 4 parametric studies have been utilized to understand the system's influential elements. From the experimental tests, it was found that using Steel Plate shall optimize the two-way action of the system and depending on the type of dry board the improvement in stiffness may reach up to 38%. It was shown from the FE analysis that the dry board, profiled steel sheeting and steel plat can affect the system by up to 10 %, 17% and 3% respectively, while applying a uniform load demonstrate a better two-way action.

Community facilities in apartment complex was developed through combination with residents' needs about housing environmental amenity, marketing competition among construction companies and social trend 'Well-being' . But community facilities and fitness center which are situated in the beginning are alienated by residents because the designers plan community facilities without considering about residents' life-style and preference. In this paper, the study includes present status of fitness center and residents' preference for proper fitness center design. The result presents that fitness center users in apartment complex want a resting space which is already located in fitness center of mixed-use residential building. A resting space provides conditions that users can make up with the community each other as well as they can rest after exercise. And the fitness center users prefer wood as interior finish material of floor and wall in exercising space and resting space because they have a feeling comfortable and splendid.

Domestic apartment housing has been designed in accordance with the new housing supply-driven policies for a long time. As a result, its design, material production, construction, maintenance and remodeling process, rather than being systematically performed, were individually approached to cause insufficient linkage between technologies. For these problems and the supply of long life housing, active research on long life housing has been conducted in Korea since 2005. However, the existing research on long life housing has been focused on a single item with no connection made between infill systems, and no overall interface rule, resulting in no activation of the business. In this study, for the supply and activation of long life housing, we aim to analyze the problems of existing long life housing to set up its matching standards for infill systems.

Range of cantilever construction that specializes in bridge and building has been extended, the process that affects the cantilever chair is the overall flow. 1926, appeared by Mart stam, cantilever chair has achieved a great development in a short period of time that has not been 100 years up to now. On the basis of age and the feature "Initial stage" - "Growth & Apotheosis stage" - "Application stage", was divided into the total three stages. And an understanding of the evolution of the cantilever chair that occupies an important part in the history of the chair design, is intended to consider the direction to go in the future.

An importance sampling method is presented for computing the first passage probability of elasto-plastic structures under stochastic excitations. The importance sampling distribution corresponds to shifting the mean of the excitation to an 'adapted' stochastic process whose future is determined based on information only up to the present. A stochastic control approach is adopted for designing the adapted process. The optimal control law is determined by a control potential, which satisfies the Bellman's equation, a nonlinear partial differential equation on the response state-space. Numerical results for a single-degree-of freedom elasto-plastic structure shows that the proposed method leads to significant improvement in variance reduction over importance sampling using design points reported recently.

As the importance of cultural information becomes greater than before, there are some needs for a new national economic paradigm in the knowledge based society. The purpose of this paper is to suggest guidelines for building up a national cultural information network model that enable to promote government's recognition and cultural policy. This research includes feasibility analysis of cultural policy perspective, current situations, and economic effect of cultural industry.

This research has a purpose to review architectural education in the early modern times in Korea. Although the mission school had some programs on basic woodworks, which were for architectural technicians afterwards, it has not been paid attention yet. Missionaries recognized the problematic situation that the most western-styled building all over Korea were built by Chinese or Japanese technicians, and they made up the minds and tried to train Korean apprentices. This training program couldn't be developed to the authorized curriculum, and moreover was limited that it was concentrated on just woodwork training; however, the missionaries made their best endeavor to overcome the deficiency of skillful technicians. At the woodwork department of the mission school there were occasionally effective programs, for example, a training of drawing or an actual participation at the real construction site. Mission schools could be said to offer the helpful programs for the early education on newly coming architecture.

The paper describes the work of the IAWE Working Group WBG - Reliability and Code Level, one of the International Codification Working Groups set up at ICWE10 in Copenhagen. The following topics are covered: sources of uncertainties in the design wind load, appropriate design target values for the exceedance probability of the design wind load for different structural classes with different consequences of a failure, yearly exceedance probability of the design wind speed and specification of the design aerodynamic coefficient for different design purposes. The recommendations from the working group are summarized at the end of the paper.

As a mass transportation system, a railway contains potential risks that may result in a high death rate and property losses. Accordingly, Railroad Safety Technology R&D Corps. is adopting the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective project management methods with Systems Engineering techniques. When a system or a service is realized, such as the Railway Total Safety Project, it needs to be verified by requirements and the process of verification is to check whether customers/stakeholders requirements have been properly transformed into a system or a service. Recently, building the standardized verification system up could be the solution to reduce possible system-failed risks. To support that, we propose the more effectual verification method of constructing the Railway Safety Test Facilities applying the systems engineering tool to the research.
