Comparative analyses of a shield building subjected to a large commercial aircraft impact between decoupling method and coupling method are performed in this paper. The decoupling method is applying impact force time-history curves on impact area of the shield building to study impact damage effects on structure. The coupling method is using a model including aircraft and shield building to perform simulation of the entire impact process. Impact force time-history curves of the fuselage, wing and engine and their total impact force time-history curve are obtained by the entire aircraft normally impacting the rigid wall. Taking aircraft structure and impact progress into account some loading areas are determined to perform some comparative analyses between decoupling method and coupling method, the calculation results including displacement, plastic strain of concrete and stress of steel plate in impact area are given. If the loading area is determined unreasonably, it will be difficult to assess impact damage of impact area even though the accurate impact force of each part of aircraft obtained already. The coupling method presented at last in this paper can more reasonably evaluate the dynamic response of the shield building than the decoupling methods used in the current nuclear engineering design.

Source criticism is very important on the research of architectural history as well as general history. In this point this research studied on the original form and change of Dokrak-dang that is very important building in architectural history of Korea. The result is as in the following. Dokrak-dang that Whoijae built at first was three by two kans size that had daecheong of four kans and ondol-bang of two kans. Gye-jeong that Whoijae built was three kans size that had daecheong of two kans and ondol-bang of one kan. After Whoijae died, Dokrak-dang's ondol-bang was changed to maru between 1555 and 1556 and ondol-bang in west side and stack room was added in 1630. Gye-jeong was changed to ㄱ-shaped floor plan that was added up two kans from three kan's 'ㅡ'-shaped one.

Today, most architectural and engineering historians no longer consider the Home Insurance Building to be the first skyscraper. Despite this, the popular belief remains that William Le Baron Jenny invented the first skyscraper when he designed the Home Insurance Building in 1884. This paper recounts the history of how Jenney won the public debate starting in 1896, despite his building being only a small evolutionary step forward. In that year, a series of letters in The Engineering Record allowed Jenney and his colleagues to engage in a public relations campaign to recast the debate about the first skyscraper to place the Home Insurance Building as the pivotal structure in skyscraper history.

중국의 조선기술은 유구하고 찬란한 발전역사를 가지고 있으며 세계 고대 조선기술사에서 아주 중요한 자리를 차지하고 있다. 지금까지 조선기술사의 연구경향은 서양 조선기술사에 편중되어 있었기 때문에 중국 조선기술사에 관한 연구는 이러한 결함을 보완 할 것이다, 인류사회의 발전과 더불어 조선기술도 급속히 발전되었다. 송대(960-1279년)에 이르러 중국의 조선업은 크게 발전되었으며, 그 특징으로는 선박의 대형화, 조선기지와 선박수량의 현저한 증가, 조선기술의 제고와 설비의 발전으로 나타난다. 송대의 조선기술은 원명(元明)시대의 조선기술 발전에 토대를 마련하였다. 따라서 교량역할을 한 송대의 조선기술을 연구함으로써 중국의 조선기술의 발전사를 알아볼 수 있을 것이다.

It could be said that the Kyongbok Palace, the main palace of the Chosun Dynasty which built in the early years of the Dynasty, had two main architectural characters. One ; the entire building complex was arranged under the influence of ancient Chinese building principle based on the Confucian ideas. Two ; building compositions and shape of each buildings were succeeded from the palace of the former Koryo Dynasty, especially on the latter periods of it. The architecture of the Kyongbok Palace had formed its own uniqueness by developing these two characters.

Frank Lloyd Wright and Mies van der Rohe are two of the most influential architects in modern architecture. In spite of the different values in their architectural lives, the design of high-rise building had been a continuous matter of primary concern for them. The purpose of this study is to compare the architectural characteristics of the two master architects in terms of building form, structure, function, and envelop skin. glass. Both of them shared with the principle of organic architecture even in the design of high-rise buildings. However, the specific approaches to realize it in high-rise buildings are significantly different. Although they emphasized the integration of building form and structure, Wright regarded the reinforced concrete structure as an organic form-giver, while Mies introduced the steel skeleton structure only as an efficient and flexible building frame. As primary finishing materials for high-rise buildings, glass was used for functional purpose by Wright, but for visual purpose by Mies.

Considering on the crisis and dilemma of monumentality in Modern architecture, this study analyse the historic reason of decay and new possibility of monumentality within the context of contemporary socio-cultural context. Historically monumentality has been considered as a main substance of High architecture in e tradition of Western Architecture. Difference between building and architecture mainly lies in monumentality which brings about esthetic quality. Usually architects take it granted that the physical and formal characteristics automatically cause the monumentality, But since the modem period the decline of communicative and representative function of architecture made this belief questionable. As Monumentality itself faced the dilemma with the modernity, ironically architects has to response to the task to handle the increasing social demands of monumental building. This study firstly shows the dilemma of monumentality in depth in case of the holocaust museum. Then we analyse the concept of monumentality itself by means of theoretical view of A. Loos and A Riegl We also analyse the change of role which monumental building played in history. Cultural and social change of context, and fundamental change of architecture old way of building a monument impossible. In conclusion this study proposes the new concept and searches new horizon of monumentality with a finding of the otherness of monumentality. Conventional monumental building language has to give way to new approaches. With some examples we already can find a new possibility.

We report for the first time the life history of a 'social' spider, Philoponella prominens, living in a temperate region. Philoponella prominens hibernated as immatures or subadults for 7-8 months in 1995 and 1996 from September-October to April-May in central Korea. When they emerged from their winter hibernation, a majority began their lives as commensals in the webs of other species. As the mating season approached, however, commensal spiders switched to become colonial or solitary. The mating season began in early June and lasted until early August. Newly-hatched spiderlings began to appear in the field in late June. They formed a colony by building their webs connected to the mother's by using pan of the mother's web as supporting substrates. As the season progressed, however, some of the colonial spiderlings became commensal or solitary individuals. Our field observations suggest that Philoponella prominens form colonies or commensal associations to reduce the web-building cost.
