The length of the links in an eccentrically braced frame will dictate the behavior of the frame. Link length controls the yielding mechanism and the ultimate failure mode. For short links, the links' shear forces reach the plastic shear capacity before the end moments reach the plastic moment capacity, and the links yields in the shear, forming a shear hinges. These links are termed "shear links." For long links, the end moments reach the plastic moment capacity before the links' shear forces reach the plastic shear capacity, forming moment hinges. These links are termed moment links." In long links, flexural yielding dominates the response, and very high bending strains are required at the link ends to produce large link deformations. In a shear links, the shear force is constant along the length of the links, and the inelastic shear strain are is uniformly distributed over the length of the links. This permits the development of large inelastic link deformations without the development of excessively high local strains. However, The use of eccentrically braced steel frames for the purpose of architectural cionsiderations such as openings and doors, areis dictating the use of longer links, though. Little data areis available on the behavior of long links under cyclic loading conditions. In This paper documents the results of an experimental program is that was conducted to assess the response of moment links in eccentrically braced frames. Sixteen specimens awere tested using a cyclic load. 편심브레이스골조의 설계에서 가장 중요한 인자는 링크보의 길이이다. 링크보의 길이에 따라 편심브레이스골조의 거동과 파괴메카니즘이 결정된다. 링크보의 길이가 짧아져 전단력에 의해 소성화되면 중심브레이스골조와 대등한 수평방향강성과 모멘트 연성골조의 연성을 동시에 확보할 수 있다. 또한 링크보의 길이가 길어지게 되면 링크보는 모멘트에 의해 소성화 되어 연성적인 거동을 확보할 수 없게 된다. 근래에 이르러 건축계획적인 측면에서는 링크보의 길이가 길어지는 것이 입면 및 단면계획이 용이하며, 그 필요성이 증대되고 있지만, 모멘트 링크에 대한 기존의 연구가 많이 수행되어 있지 않으며, 이와 관련된 자료가 부족한 실정이다. 본 연구에서는 실험을 통해 다양한 접합디테일을 가진 모멘트링크보의 거동을 규명하고 모멘트링크보의 거동을 개선시킬 수 있는 접합디테일을 제시하고자 한다. 4개의 접합 디테일을 가진 총 16개의 실험체를 계획하여 이력거동 실험을 수행하였다.

구한말(舊韓末) 외인건축술(外人建築術)의 전래과정(傳來過程) 연구

김태영,Kim, Tai-Young 한국건축역사학회 1992 건축역사연구 Vol.1 No.1

The purpose of this paper is to clarify the introduction of foreigner's architectural engineering such as building materials techniques engineers, focused on the Late Yi-dynasty. Such all kind of building materials as timber brick tile cement lime glass window furniture and so on was imported from the foreign company in opening period of ports in Cho-son. The timer of these materials was imported from Japan, the brick tile from China, and others directly from Western counteries indirectly from Japan China. As it was active in an inflow of building materials and machines about 1890's, the modern building techniques were introduced and elementarily mastered such as timber sewing, manufacturing baking of brick glass, and masonry, The above modern techniques became the direct background in the formation of Korean modern architecture. Building engineers can be divided into three classes : architect engineer apprentice. But It could be apparently not divided the relation between architect and engineer at that time. They could be classified into job-architects who were engaged by the Korean government and leaded an active life in their settlement, and missonaries, They introduced the construction and style of modern architecture in our country, And so many skilled laborers and laborers participated in the construction of their settlement.

When the castle of the city was destructed from 1911 through 1915 in Cheongju, the city's spatial structure was reorganized and "Han-ok Housing", a dwelling site filled with Korean traditional houses, was newly formed around the former castle site. These days, the Han-ok housing in Seoun-dong, Cheongju in which elderly couples and senior citizens live is enclosed by modernized roads and three or four-story buildings, leaving the housing as an isolated island in the city block. Nonetheless, the Han-ok housing not only plays an important role in sustaining the historic and local identity of the city, but also offers environmental benefits in terms of daylighting and ventilation. The purpose of this study is to reorganize the housing suitable for those who currently live and recreate it by adding new functionality. Consequently, three strategies are established; the conservation of existing building through the improvement of existing facilities; the conversion of vacant buildings into a new use; and the creation of the urban mid-rise Han-ok housing at street sides. The first strategy has a significance in that the traditional building's single wing plan, small room sizes and lack of storages now cause great inconvenience for current life style. The second strategy also promotes the practical use of abandoned buildings through alterations and additions. Finally, the creation of the urban mid-rise Han-ok housing that is accomplished by the combination of reinforced concrete and wooden structure interacts with or respond to the city's development. As a result, this study for the adaptive reuse of Han-ok housing proves how the traditional properties can be maintained in a careful manner and how its creative reuse can be achieved.

Many cultural heritages for the modern ages in Korea are becoming lost rapidly as a result of subsequent technological innovation and changes in industrial structures and other reasons. But they are indispensable for an understanding of history, tradition culture of Korea, and form the basis for development and advancement of future culture at the same time. Therefore, this study is aimed to review the protection of cultural heritage in Japan, establishing the protection policies in Korea. In Japan, The Advisory Committee for the Preservation and Utilization of Modern Cultural heritage was organized by The Agency for Cultural Affairs. And this classified modern cultural heritage into four fields, as like; (1)monuments, (2)buildings, (3)fine arts and historical heritage, and (4)life, culture, and technology to pursue concrete research and study. The next step is tarrying out investigations to identify these cultural heritages, which were once the backbone of Japanese modernization and are now in the process of being lost, in an effort to preserve them as cultural heritage of the Japanese modernization period. The investigation will have conducted on an about eight year scheme starting with 1996. And it's will ask all local boards of education(of the prefectures, cities, towns, and villages throughout the country) to supply all related records or documents available and to cooperate in field studies. So now, many cultural heritages for the modern ages in Japan have been designated as Important Cultural Properties, Registered Tangible Cultural Properties, Monuments, etc. And they have been prepared various tax policy(ex, reduction of the real estate tax). Also, that's examples are not only one by one but magnified with protection of large-scale construction associated with region. In addition, magnified with region's activities. In conclusion, in the process, protection has been extended to a broader variety of cultural properties and much consideration has been given to the methods of protection in Japan.

정보통신기술의 발전으로 컴퓨터에 대한 의존도가 높아지고 있다. 이런 높은 의존도는 곧 사이버 보안적인 측면에서 문제가 생길 경우 국가적으로 큰 혼란이 발생한다는 것을 국내에서 발생한 사고들을 통해 알 수 있다. 이에 대응하기 위해 많은 보안 솔루션들이 존재함에도 불구하고 보안 사고들이 지속적으로 발생하고 있는 것은 특정 기능에 국한되어 중복과 취약점이 존재하고 있기 때문이다. 이러한 정보보호 환경의 한계를 극복하고자 새로운 개념의 SDN을 활용한 검역 시스템을 제안되었으며, 본 논문에서는 SDN을 활용한 검역 시스템 내에서 적용할 로그 분석 시스템을 제안한다.

We argue that organizational scope and niche crowding increase the rate of technological innovation, particularly in the case of incremental innovation, while prior experience in another industry lowers the rate of both incremental and radical innovation. Further, we argue that while innovation itself may improve an organization's survival chances, its simultaneous occurrence with other organizational changes such as a change in market position is likely to lower its survival chances. Using data on all American automobile manufacturers from 1885-1981, we find substantial support for our predictions. Our results are consistent with the implications of a cascading model of organizational change with incremental innovations providing survival benefits and radical innovations lowering survival chances when they occur jointly with market position change.

Nowadays, in the constructions of large-scale structure, there is applied top-down construction method for the purpose of the safety of building construction and the effects of a shortening term. In the design of headed stud connectors encased column base, shear strength of stud connector have followed the shear strength evolution of composite steel-concrete beams. The purpose of this paper is to compare stud shear strength evolution of encased column base with that of composite beam. Push-out specimens were tested by each parameter of horizontal reinforcements(hoop, D10@100), stud diameter(Φ13, 16, 19, 22). and concrete compressive strength(F_c=240, 300 ㎏/㎠). And the other aim of this paper is to acquire the basic data of structural design calculated to the number of headed stud connector.
