보물 제1746호로 지정된 논산 노강서원강당은 2008년 정밀안전진단, 2015~2017년 주기적인 모니터링 결과에 따라 2017년 보수정비기본계획을 수립을 통해 현재 기둥이상 해체수리를 진행하고 있다. 강당의 건립시기는 기문헌(『노강서원지』, 각종 보고서, 문화재 안내 등)에서 1675년으로 보고 있으나, 해체 수리 과정에 서 확인된 중도리와 대공의 묵서, 기와 명문, 주요부재의 연륜연대 조사 등의 결과를 종합하여 창건시기를 검토해본 결과 1695년으로 확인되었다. 조선후기 서원의 기능이 교육에서 향사 중심으로 이동한 사실에 비춰본다면, 기존에 알려진 1675년 노강서원은 사당 중 심의 영역으로 건립된 후 1682년 사액을 통한 재정적 뒷받침을 바탕으로 1695년 강당을 신축한 것으로 보는 것이 타당하다 고 판단된다.

A very unique case is found in the architectural remains related to the north and south square-platform at the lecture hall site of Hwangnyongsa, that of Anyangsa, and the estimated lecture hall site of Beopsusa as they are not observed in the other lecture halls. The platform has been discovered at only those three Buddhist temples from Goryeo, and its case has not been found in ancient Buddhist temples of China and Japan. This study thus set out to investigate the north and south square-platform at lecture hall sites by examining in details its architectural remains at the three Buddhist temples and reviewing the Buddhist literature about the lecture halls of ancient Buddhist temples. Based on the findings, it was estimated that the architectural remains of north and south square-platform at the lecture hall sites of Buddhist temples were those of platform for Buddhist sermons or those of high chair platform. While the north square-platform involved the remains of north high chair for the Lecturer that gave lectures on the Buddhist scriptures, the south one did those of south high chair for the Reader who recited the Buddhist scriptures.

Jeongrimsaji as temple remains of Baekje Sabi period, its re-excavation has been carried three times in full scale. As a result, the buildings in left and right of lecture hall was largely identified in 3 forms. First, layout of small buildings in left and right of lecture hall. Second, layput of corridor in left and right of lecture hall. Third, layout of construction site in the north of corridor in left and right of lecture hall. Above second is included into remains of Gorye, the third is included into remains of Baekje - the remains were almost ruined then. The first form and third form in above is different each other in size of buildings, form of layout, and location. It is important to investigate these points: the time of constructing the buildings; what position have the use and function of the buildings in the temple? ; transition process of layout of the Buddhist temple. In this context, of temple remains in Baekje during the 5~7th century, the cases where construction sites in left and right of lecture hall and construction site in the north of corridor are identified, have been reviewed. Based on this review, the use and function of buildings, their transition process were investigated. The survey results show that small buildings in left and right of lecture hall existed in the middle and later period of the 6th century. During the later 6th century ~ the 7th century, construction site in narrow and long square shape was located in left and right of lecture hall instead of small buildings in the north of corridor. Therefore, it is identified that the aforementioned thing is earlier stage and the latter thing is later stage.

This study was to analyze the architectural characteristics and facade construction of brick masonry auditorium through the Auditorium of Namsan Primary School in 1936. The results of this study were described separately as follows. 1. The auditorium is located away from the school buildings, and its plane is a chamber of rectangle type with an entrance installed on each of the four sides. 2. The external appearance is Renaissance eclectic style, laid red bricks on the lower wall of the window and having a mansard roof. The front and the rear are symmetric with respect to the projected wall at the center. 3. As to the structure of the building, a concrete lower wall was built on the concrete continuous footing, and the brick wall was constructed on the lower wall. The roof is queen post roof truss, and the wall girders were installed on the brick wall. 4. The auditorium has had a number of repairing and maintenance works, which changed the roof and windows outside and the floor, walls, ceiling, etc. inside. 5. The decorative elements of external appearance include lower wall, brick wall, entrances, windows, roof, and dormer windows. The brick wall gives verticality and solidity to the surface of the wall, and the lower wall and wall girders are connected like a cornice of the wall. The surface of the mansard roof and dormer windows express a stable vertically oriented shape.
