The purpose of this study is to analyze the legislation types and prescriptions of American earth building codes. The process of this study is as follows: (1) To understand the legislation background of American earth building codes, this study investigated the history and present state of earth building techniques which is used in USA. (2) To understand the legislation method and procedure of American earth building codes, this study investigated the legislation system of American building codes and the process of model building codes development and adoption. (3) To provide basic data for the legislation of Korean earth building codes or guidelines, this study analyzed American earth building codes about adobe, compressed earth block and rammed earth. The result of this study is as follows: (1) To meet need of a single coordinated set of national model building codes in the United States, the nation's three model code groups decided to form the International Code Council and the first edition of the International Building Code was published in 1997. In the International Building Code there are prescriptions on adobe construction. (2) There are three legislation types of earth building codes in USA. First is to use prescriptions of International Building Code on adobe construction. Second is that State governments establish and issue a separate document under its own title. The last is that local jurisdictions adopt International Building Code with amendments or additional rules. (3) On the base of analysis of American earth building codes, this study proposed the legislation process and direction of Korean earth building codes and guidelines.

The purpose of this research was to analyze the connections of the seismic-performance values for domestic-performance-based designs. Basic research on the performance design method has been increasing of late, along with performance-based organization investigations. These investigations concern the performance level state of steel structure buildings. According to the performance limit state, seismic-performance values should be presented as appropriate steel structure engineering amounts. The first step, based on the full-scale steel structure experiments, involves researching on the making of a basic document. The moment-rotation angle relationship results of the experiment on the moment-frame connection were used to assort the functional and undamaged limits, which were assumed to be less than the yield moment. Moreover, the repairable and safety limits, which were assumed to exist between the yield and maximum moments, were assorted by investigating the accumulated plastic deformation ratio.

The RC private constructions represent a large part of the housing stock in the north part of Algeria. For various reasons, they are mostly built without any seismic considerations and their seismic vulnerability remains unknown for different levels of seismic intensity possible in the region. To support future seismic risk mitigation efforts in northern Algeria, this document assesses the seismic vulnerability of typical private RC constructions built after the Boumerdes earthquake (May 21, 2003) without considering existing seismic regulation, through the development of analytical fragility curves. The fragility curves are developed for four representative RC frames in terms of slight, moderate, extensive, and complete damage states suggested in HAZUS-MH 2.1, using nonlinear time history analyses. The numerical simulation of the nonlinear seismic response of the structures is performed using the SeismoStruct software. An original intensity measure (IM) is proposed and used in this study. It is the zone acceleration coefficient "A", through which the seismic hazard level is represented in the Algerian Seismic Regulations. The efficiency, practicality, and proficiency of the choice of IM are demonstrated. Incremental dynamic analyses are conducted under fifteen ground motion accelerograms compatible with the elastic target spectrum of the Algerian Seismic Regulations. In order to cover all the seismic zones of northern Algeria, the accelerograms are scaled from 0.1 to 2.5 in increments of 0.1. The results mainly indicate that private constructions built after the Boumerdes earthquake in the moderate and high seismic zones with four (04) or more storeys are highly vulnerable.

The purpose of this study was to analyze the planning characteristics and it's applications of container architecture in Seoul and Kyunggi Area. A document research and field survey were used to analyze and classify the spatial characteristics of the container architecture since 2009. Based on the results of the critical review, this research proposed a framework to identify the potential of the container architecture for sustainable and flexible planning. The framework was composed of four dimensions such as flexibility, rapidity, sustainability and economic feasibility. The types of space construction were dynamically self-erecting structure, incremental structure, mobile and disposable architecture. The spacial aspects were commercial spaces, housing spaces such as dormitory and urban compact apartments, and the multi-purpose spaces such as gallery and culture space as well as temporary spaces. It attempted to resolve the concept of flexibility and mobility through the experiment so that they might apply to the space of contemporary city.

As China enters the 21st century, China is strengthening its position as a world power in an international position. However, there are still problems with Three Agricultural(Agricultural, Rural, Farmer) and unbalanced urban and rural villages. China, as one of the largest and most populous nations, values the development of three farms. Strategies such as "The Construction Of New Socialist Countryside" were a policy to solve rural problems, But they were not enough to achieve breakthrough results. In order to achieve more effective results, the Central Committee of THE STATE COUNCIL proposed The Document No.1 of "Opinion on the Implementation of The Rural Revitalization Strategy" in February 4, 2018 and published "The Rural Revitalization Strategy (2018-2022 )". The Yanbian region, which is the subject of this study, is the home of Korean-Chinese tribes and the Korean autonomous region. As a minority of Chinese ethnic minorities, the Korean-Chinese has their own unique culture, and Yanbian has distinct regional characteristics. As The Rural Revitalization Strategy was raised, Villages is showing positive change in accordance with policy implementation in Yanbian. This study analyzed the current status of policy implementation of The Rural Revitalization Strategy in Yanbian area and analyzed the policy contents and performances based on the of Yanbian Daily News. Based on the results of the analysis, I would like to help in suggesting a more rational development direction and building the villages.

The purpose of this study is to scrutinize forefathers' standpoint on architectural planning by peering into their literature. Dongkukyisangkukjib which contains works about daily life of Lee Gyu-Bo, a great writer in the middle of Koryo, reveals well people of Koryo' thought on architecture, if we have a interest in a building space. The book holds his general viewpoint on architecture and documents about the remarkable houses he and his friends visited. Then we can know, through it, general thought on architecture of the upper classes in those days. Lee Gyu-Bo considered a house the other self of its owner and connected buildings with personality of their owner. 0 architectural process and architectural planning, buildings were shown variously by reflecting owner's value on architecture. Unlike Chosun era, people of Koryo prefer unlimited thinking to form or order. Therefore in construction especially such as a pavilion, there were many experimental tries which reflected owners' thought. Particularly we could estimate people of Koryo' conception of architectural design through a work of Lee Gyu-Bo, Saryunjungky, a document about a pavilion carrying four wheels, which describes concretely contents of architectural planning such as a planning of space, module, and intention.

Collections in the buddhist statue owned by Dr. Jong-Hm Baik(白宗欽) included 3 ancient documents and 2 wooden cylinders that showed a clear historical order. The temple and buddhist statue that these objects were belonged to were not known, however, according to the document, it could be inferred as Chunsukwaneumsang(천수관음상) created in 1322 and reformed in 1614 from the list of donator for the statue. Inside a wooden cylinder, a bundle of ivory, yellow, green, orange, and dark brown fabrics that were folded up and tided up with 5 different colored thread strands and aromatic trees and rice plant was placed on the bottom. All the fabrics were silk. Three thread strands were silk. The white and blue strands were cotton fibers as a result of analysis of IR spectrum and the microscope. According to a radioactive carbon isotope dating by accelerator mass spectroscopy, years before present was 160$\pm$40, and cablibrated ages were 1680-1890 (79.3$\%$), 1910-1960(16.1$\%$) in 95.4$\%$ probability. Accordingly, the fabrics in the buddhist statue proved to be reformed in 1614 not the original ones in 1322.

The amount of Meta-data to be managed increases with development of information technology. However, when trying to integrate and share product information of heterogeneous systems within or between companies, sharing of information is impossible if product information classification systems are different. Due to the situation mentioned above, engineers judge the product information classification system and maps corresponding Meta-data for document-based sharing. Judging exponentially increasing amount of data by engineers and sharing product information using documents create great amount of time delay and errors in data handling. Therefore, construction of a system for integrated management and interoperability between product information based on semantic information similar to engineer's judgment is required. This paper proposes a methodology and necessity of a system for interoperability of product information based on semantic web, and also designs a system to integrate heterogeneous systems with different product information using rule based reasoning. This paper also suggests a system base for interoperability and integration of product information between heterogeneous systems by integrating the product information classification system semantically.

We study the impact of economic policy uncertainty (EPU) of Asian four countries such as Korea, Japan, Hong Kong, and China on housing market returns in Korea. Also, we document the relationship between the EPU index of those four countries and the housing market including macroeconomic indicators in Korea. The EPU index of those four countries has significantly a negative effect on the housing purchase price index, housing lease price index in Korea. The EPU index in Korea and Japan has significantly a negative effect on the CPI. The EPU index in only Japan has significantly a negative effect on the PPI. The EPU index in Hong Kong and Korea has significantly a negative effect but the EPU index in China significantly has a positive effect on the stock price index in construction industry. The EPU index in only Korea has significantly a negative effect the stock price index in banking industry. This study shows the EPU index of the Korea has the negative relationships on the housing market economy rather than other countries by VECM. And this study has an important evidence of the spillover of several macroeconomic indicators in Korea for the EPU index of the Asian four countries.
