This study sought to reveal the architectural characteristics of Quonset church built in the Archdiocese of Gwangju, and the conclusions are as follows. The Quonset structure, which was used as a military barracks during World War II and was designed to be easily assembled and disassembled quickly, was used in Damyang, Hwasun, and Gokseong churchs. They were all built in 1958, after the Korean War, and can be related to the historical background of the rapid increase in the number of Catholics. They are utility buildings that can accommodate many believers, that is, large quonsets measuring 40 feet (width) x 100 feet (length). The floor plan was largely divided into two spaces, with about 3/4 reserved for the nave and altar, and the remaining 1/4, or 24 to 30 feet, used as a sacristy or confessional. The cross-section is a semicircle with a radius of 20 feet, framed by 6-inch ribs, and its unique structure, in which bricks are stacked on the outside to form the exterior, makes it different from a typical brick church. Unlike other stone churches built around the same time, Quonset church was not expanded. This may be due to the difficulty in supplying special materials such as the ribs that make up the frame, as well as the absence of relevant experts.

Recently, the occurrence frequency of earthquake has increased in Korea, and the interests for seismic reinforcement of existing school buildings have been raised. To this end, the seismic performance evaluations for school buildings that did not accomplish the seismic design are required. In particular, this study checks the eigenvalue analysis, pushover curves, maximum base shears, performance points and story drift ratios, and then analyzes the seismic performance characteristics according to bracing configuration of steel frame system reinforcement. Also, this study presents the practical field application methods through the comparison of analysis results for the seismic performance characteristics.

J ogyeongdan is an altar built by the Korean Empire within the burial grounds of Sijomyo(始祖墓), the Jeonju Lee clan, as a part of their posthumous respecting project. This site adheres to strict rules and formalities that are comparable to those of the royal tombs of the Joseon Dynasty, with its altars and monument House demonstrating construction techniques that hold high value in architectural history. This study compares and analyzes construction-related records such as Uigwe, Statements, and Figure, along with their historical context. Through this effort, the study explores in detail the original form of J ogyeongdan at the time of its construction and subsequent transformations in later periods. Findings showed that the Figure was drawed by Chae Yongsin and was only a blueprint prior to the construction; it was modified during the actual construction process. A part of J ogyeongdan project was carried out by demolishing four government office buildings that were closed because of the Gabo Reform in order to secure wood and roof tiles, among other materials. Additionally, concluded the J aesil was by relocated Deokryudang from Samryeyeokcham. Further, instances of distinctive terminology usage were found related to construction materials in the J ogyeongdan Uigwe , which were not used in another Uigwe . These terms were distinguished in detail according to the locations in which the materials were used.

Homogot Lighthouse is located in Pohang of the easternmost of Korean Peninsula. Homogot has become first known as Cape Clonard in the West through the navigation log by La Perouse, a Frenchman who embarked on a global exploration in 1785. Homogot Lighthouse represents an outstanding accomplishment of modernization that numerous civilized countries scrambled to attain in the early 20th century. Located where the geographical risk of earthquakes is high, the structure was nonetheless built to be 26.4m high with brick masonry. Structurally safe and aesthetically graceful, it demonstrates neoclassical ideas superbly in terms of style as well. Although the history of Asian lighthouses is shorter than that of European ones. Homogot Lighthouse, which demonstrates the history of a modern lighthouse along with those in Japan and China, is differentiated by the following characteristics. ① The ‘living lighthouse heritage’ is linked to one of the largest lighthouse museum in the world. ② Where you can see the earliest sunrise at the easternmost of the Eurasian Continent. ③ The completion of a modern-style lighthouse constructed at the easternmost of the Far East after being initiated in Europe. ④ Differentiated historical, architectural, and aesthetic value. ⑤ The heart of the national marine park.

Jogyeongmyo Shrine is the Sijomyo Shrine of the Joseon royal family. It is a representative building that symbolizes Jeonju, the hometown of the Joseon royal family. This study comprehensively analyzes a variety of literature, old maps, and figures, and it investigates the meaning of Jogyeongmyo Shrine as an architectural example as well as its architectural characteristics. The Jogyeongmyo Shrine was built to symbolically demonstrate the superior virtue of the royal ancestors compared to the ancestors of the gentry. King Yeongjo built Jogyeongmyo Shrine, which he considered his greatest achievement, to raise the status of the royal family and exact loyalty from the vassals. Jogyeongmyo Shrine is a unique example of an ceremonial architecture that cannot be observed in China or the previous Korean dynasties. In addition, its architecture looks different from that of ordinary shrines because both Confucian ceremonies and the function of each building were taken into consideration during construction. Although Jogyeongmyo Shrine was preserved without significant changes until the late Joseon dynasty, major modifications were made in all areas except the main shrine area during the Japanese colonial era.

This study chiefly aims to clarify efficient methods considering behavioral pattern of refugees in multi-use facilities which can be applied to architectural planning. Accordance with COVID-19 situation, it is mandatory to check the temperature of visitors as a measure for the prevention of COVID-19 in multiuser facilities. When disaster occurs, for people in multi-use facilities such as medical facilities, museum, concert hall etc, it is difficult to find out short and right route to outside since the spatial characteristics are not familiar to visitors. If we design floor plans and circulation system considering behavioral pattern of refugees we can prevent the spread of disasters when they happen.

In this research, the case of modern wooden structures since 1950 with span of 30m or more was investigated and analyzed the construction status and structural planning characteristics of wooden large space architecture. As a result, wooden large space buildings have built around Asia, North America, and Europe, in which cases of ice skating stadiums with span of 30m to 60m were concentrated. In the case of baseball parks and football stadiums, even a span of about 165m was built in a wooden structure. In addition, it was found that the structural systems used in wooden large space structures were a funicular arch and truss structure, in that cases, funicular arch system consisting of radial arrangements was used in the examples exceeded 150m and the two way truss system was also used in long span wooden structures exceeding 100m. As the truss structure with a tie-rod or the flexure+tension structure was partially investigated, it can be seen that various timber structural systems need to be devised and researched. Also, It was investigated that a technique in which some members of the truss are made of steel or a composite member of steel and timber is also possible to develop

The remaining Joongjaesil(中齋室)-type pavilions in the eastern part of the Jirisan Mountain area showed more complex characteristics than those in the western part. The front number of kan(間) had two, three, and four kan (間) types, but the number of kan on the side was consistent with two regardless of the number of kan on the front. The pavillion is classified into 'central type', 'towards the backward type', and 'expanded by backwards type' according to the location of Joongjaesil. Joongjaesil's size, which characterizes the characteristics of Joongjaesil-type Pavilion, is related to the building's front number of kan. Front number of kan. When this space was increased by one space to four spaces, Joongjaesil must have two spaces. The pavilion with four bays in front showed the characteristics of being concentrated in Sancheong and Jinju, the eastern part of the Jirisan Mountain area. In the eastern region, many high pavilions remain, and the upper structure of the pavilion was insignificant, but the flat shape and public construction showed strong locality.
