우리나라의 바람은 계절풍, 태풍, 저기압 전선풍으로 나눌 수 있다. 또한 우리나라는 산지가 많고 삼면이 바다로 둘러싸인 지 리적인 특성도 갖고 있다. 이로 인해 각 지역의 풍향마다 풍속이 균일하게 불어오지 않는다. 내풍설계 시 사용하는 풍속은 건축구조기 준에 규정된 100년 재현기대풍속을 전풍향에 대해 동일하게 사용한다. 이 값은 풍향을 고려하지 않기 때문에 다소 보수적인 설계가 될 수 있다. 이 연구에서는 10개 지역을 대상으로 16풍향에 대한 분풍속을 수집하여 풍향별 100년 재현기대풍속을 산출하였다. 기상청에 서 수집한 자료를 균질하게 하기 위해 풍향별로 유효높이를 고려하였고, 지표면조도구분을 하는 방법으로 가스트계수방법과 목측방법을 사용하였다. 풍향별 100년 재현기대풍속을 산정하기 위한 확률분포는 Gumbel분포를 사용하였고, 경험적 초과확률로는 Hazen방법 을 이용하였으며, Gumbel분포와 Hazen방법의 적합성은 적합성평가함수에 의해 판단하였다. 이것을 토대로 각 지역의 풍향계수를 산출하였고, 풍향계수의 비교를 통해 지역별, 풍향별 풍속의 특성을 파악하였다.

This study mainly inquired characteristics and changes of 'Chang-aelgool' through 38 cases(with 161 Ssang-chang) of annex and pavillion buildings in Yeong-nam region which are built during the Chosun dynasty. The method of inquiry included actual survey of windows along with bibliographical research, and the results are as below. First, through the discovery of the term 'Chang-aelgool' as an indication of the window-forming frame in 'YeongGeonUiGwe'(1680 A.D), it is apparent that the term 'Chang-aelgool' was widely used in Korea from the late 17th century. Second, the 'Chang-aelgool' of study objects are classified into 4 categories. Type Ⅰ and Ⅱ are comprised of mitre-joints which cover the 4 corners of 'Chang-aelgool' and mainly used in building annex and pavillion buildings during the early period of the Chosun dynasty. Type Ⅲ was widely used during the early and middle period of the Chosun dynasty and drastically dropped in number during the late period of the dynasty. Type Ⅳ is comprised of mitre-joint of the upper-half, tenon-jointing of the lower-half and widely used in annex and pavillion building during the late period of the Chosun dynasty. Third, the form of 'Chang-aelgool' has changed from rectangular form with longer width during the early period of Chosun dynasty to square form during the middle period and eventually ended up as a rectangular form with longer height during the late period of the dynasty. Fourth, it is considered that while mullion which is located in the center of 'Chang-aelgool' was mainly used around the main floored room during the early period of the Chosun dynasty, became commonly used in main floored room and 'ondol' rooms during the middle period and drastically dropped in number from then and ended up being not in use after the mid 18th century.

Studies and reports on buddhist temples in Goryeo dynasty are rarely in the present situation. At this point of time new excavational reports and historic records offer many materials to understand a architecture in Goryeo period. Especially, temple site have various transitions, it is of great value to study. This article attempted a restorative study of a location, function, spacial arrangement, structure, building age is based on a measure and transition of temple layout that is based on the excavational result and related historic documents about Godal temple site in Yeoju. Godal temple site was a representative Zen buddhist temple in Goryeo Dynasty. It was difficult of access by watercourse because it was located in an inland in the upper Han River. Archaeological research and historical records has reveals that the temple was constructed with a minium of four levels[six terms]. We could recognized the central site of temple and buildings were constantly established, enovated or collapsed. It has went through many transition according as it encountered new sects and doctrines. Also it should perform various functions and overcome given conditions. Ultimately it let see greater diversity in the spacial composition, and layout. That is to say it were planed several separate areas, each was consisted of main buildings, once again was integrated into one temple.

As the aging of the facility increases, the safety, durability, and serviceability that were originally possessed by the natural aging deteriorate. Accordingly, periodic safety inspections, repair and strengthening are the basic procedures for th maintenances of facilities. However, except for some facilities that are prescribed in the law, the safety and maintenance of facilities are still insufficient. Especially, social welfare facilities, which occupy the majority of small-scale vulnerable facilities, have a high proportion of old facilities with many years of age, leading to major damages that affect the durability and safety of facilities. The purpose of this paper is to identify the main damage and its causes according to the change of the years of social welfare facilities, and to use it as a basic data to suggest reasonable maintenance methods.
