Following the social requirement to strengthen field supervision of the asbestos containing materials (ACM) abatement process with regard to asbestos school buildings, this study was conducted to understand the status and characteristics of airborne asbestos that may potentially occur after the ACM abatement process is completed. In the area where a series of asbestos abatement processes were finally completed, comprehensive area air sampling was performed. For sample analysis, Transmission Electron Microscopy (TEM) was used according to The Asbestos Hazard Emergency Response Act (AHERA) method and Phase Contrast Microscopy (PCM) analysis was also performed. Airborne asbestos was detected in 29.5% of the total samples, and the average concentration was 0.0039 ± 0.0123 s/cc (12.3 ± 38.9 s/mm2). 4.5% of the total samples exceeded the AHERA standard (70.0 s/mm2) and the average concentration was 0.0528 ± 0.0256 s/cc (167.2 ± 82.0 s/mm2). Airborne asbestos was no longer detected at the point when AHERA is exceeded after re-cleaning. Most of the detected asbestos was chrysotile (94.4%) and the structure types of asbestos were Matrix (41.4%), Fiber (39.9%), Bundle (10.8%), and Cluster (7.8%). Among the asbestos structures detected through transmission electron microscope analysis, the asbestos structures satisfying PCM-equivalent structures were found to be 6% of the detected asbestos, indicating that there is a limitation of the PCM analysis to check the airborne asbestos in that area. As a result of reviewing the status of airborne asbestos that may potentially occur and the type and dimensions of asbestos structure detected in the area, since the airborne asbestos exposure caused by poor field supervision for the ACM abatement process could not be ruled out, thorough management is necessary. In addition, the result of this study could be used as scientific evidence for establishing and strengthening policies related to ACM abatement, including cases of school buildings.

우리나라는 삼면이 바다이며 북쪽과 동쪽으로 산지가 위치하고 서쪽으로는 평탄한 지리적 특성을 가진다. 또한 계절풍, 태풍 등의 바람이 지리적 특성으로 인하여 지역마다 풍향별 풍속이 다르다. 그러나 건축구조기준(이하 KDS 41 12 00: 2019)은 전풍향에 대 해 동일한 풍속을 적용한다고 규정하였고, 이것은 상대적으로 약한 풍향에 대해 과다한 풍속을 적용할 수 있다. 이런 점을 고려하여 건 축구조기준(이하 KDS 41 12 00: 2022)에서는 합리적인 설계를 위해 풍향계수를 적용한다. 본 연구는 8개소를 대상으로 10년간의 자 료를 수집하여 사용성 평가를 위한 1년 재현기대풍속과 풍향계수를 산출하였다. 선행 연구된 논문에서 사용성 평가를 위한 1년 재현 기대풍속과 풍향계수를 산출하였으나, 이는 기상청에서 제공하는 일최대풍속으로 산출하였기 때문에 누락되는 풍속이 있을 수 있다고 판단되었다. 따라서 분풍속을 이용하여 모든 풍향의 일최대풍속을 구하였고, Weibull 분포를 통해 재현기대풍속을 산출하였다. 최종적 으로 기상청에서 제공하는 일최대풍속으로 구한 풍향계수와 분풍속으로 구한 일최대풍속의 풍향계수를 비교하여 지역별 풍향계수의 경향 및 두 방법의 차이점에 대해 분석하였다.

Recently, local studies looking at the 'local(region) as a whole' are gradually increasing. The study of local architectural history is important in that it provides specific information that encompasses the local and the entire and clues to three-dimensionalize the time and space in the local. To infer the 'presentness' of each era, reliable data in various fields are needed. Recently, as many databases (DB) and archives, from the 'National Archives of Korea' to other local archives, have been established and publicized, research resources in the local are growing rapidly in quantity and quality. Nevertheless, it is difficult to comprehensively check the data necessary to study the local architectural history(local architectural history research resources). Against this background, this study confirmed the trend of changes in the archive construction environment and the status and problems of local architectural history research resources in places that currently disclose local history research resources among generalized web-archives. Next, the relationship between the actual research on local architectural history was confirmed through the analysis of existing studies and the data used for Jeju. As a result, local studies, local archives, and local architectural history research agree with recent changes in local research trends, and the degree of archival construction has reached the same level as the available research resources except core data in local architectural history research. However, there is a problem that the density of information that can be used is low because the local architectural history research resources that can be obtained are fragmented because there are no archives and construction entities specialized in local architecture. As each archive has entered the stabilization and upgrading stage, the construction of new archives needs to be reconsidered, but it is time to find a detailed way to link related information quickly and accurately, such as private records, to reduce the gap in information needed in terms of research on local architecture and architecture history.

Korean architecture classifies Banja (the decorated flat of the ceiling visible from the inside) of Royal Palaces into two types: Woomul(water-well, 井) banja, which inserts rectangular wooden board into lattice frame, and paper banja, which applies paper to the flat ceiling. Such classification was established in the 19th century. Before that, Banja was classified according to what was inserted into the lattice frame, either wooden or paper board. At first, the banja that used paper board was widely installed regardless of the purpose or nobility of the building. However, since the 17th century, the use of paper board banja became mostly restricted to Ondol (Korean floor heating system) rooms which are characterized by private usage and the importance of heating, and it was considered inferior to wooden board banja in terms of rank or grace. The contemporary paper banja was mainly installed in low-rank ondol rooms until the late 19th century to early 20th century, when roll-type wallpaper was introduced from the West and the paper banja came to decorate the King’s and Queen’s bedrooms. The traditional paper board banja benefits heat reservation, reduces the weight of the ceiling, and allows the adjustment of the lattice frame size. Furthermore, it can feature unique artistry if covered with blue, white, or red Neung-hwa-ji (traditional flower pattered paper).

The purpose of this research is to investigate Korean architects’ perception of the Modern Movement in architecture in the West during the Japanese colonial period, by analyzing two Korean publications in the 1930s: Park Dongjin’s ‘Present Architectural Tendency’ (Dong-A Ilbo, March 1931) and Hong Yunsick’s ‘Trend in the Thought of Moderne Baukunst’ (Chogwang, September 1937). As a result of the investigation, it is confirmed that the two men welcomely accepted the universal modernity, regarding the rational and functional - rather than subjective expressions of the individual - as the key to modern architecture. Although their perception of the Modern Movement in Western architecture was inevitably superficial due to the limited condition of the Japanese colonial period in Korea, there was an obvious advancement in the latter’s perception from the former’s, reflecting the progress in knowledge of it over the six and a half years between the two. Therefore, it is argued that their 1930s’ writings are meaningful as the first Korean publications that illustrate how Korean architectural circles perceived the contemporary architectural movement in the West.

The construction method of scaffolding structures is different from Mortise and Tenon and bucket arch structure of traditional large woodwork. It forms an independent construction system-fixing nodes with knots, a large number of diagonal braces are used to fix shelves and the structures mostly contain X-shape and triangular shape details. Simple ones include stalls, sheds, rain sheds, altars, lamp racks etc. But the scaffolding with larger scale and more complicated structure are modeled on archways, theatres and other buildings which are used in commercial and festival activities. At present, Macao, Hong Kong, Guangdong, Sichuan, Shanxi and other places in China have retained the custom of using scaffolding structures in important festival activities, but their uses, techniques and building types are slightly different from place to place. Due to building and demolishing at any time, the construction and service cycle is short. As a result, there are almost no physical objects left. We can only deduce the use and technical characteristics of ancient scaffolding skills through the colorful building styles that have been preserved with folk activities in various parts of China, the craftsmanship handed down from generation to generation by the scaffolding guild and artisans, and the description of cultural and historical materials and the mutual corroboration of visual materials.

Structures of high-rise buildings are less prone to earthquake damage. This is because the response acceleration of high-rise buildings appears to be small by generally occurring short-period ground motions. However, due to the increased construction volume of high-rise buildings and concerns about large earthquakes, long-period ground motions have begun to be recognized as a risk factor for high-rise buildings. Ground motion observed on each floor of the building is affected by the eigenmode of the building because the ground motion input to the building is amplified in the frequency range corresponding to the building's natural frequency. In addition, long-period components of ground motion are more easily transmitted to the floor or attached components of the building than short-period components. As such, high-rise buildings and non-structural components pose concerns about long-period ground motion. However, the criteria (ASCE 7-22) underestimate the acceleration response of buildings and non-structural components caused by long-period ground motion. Therefore, the characteristics of buildings’ acceleration response amplification ratio and non-structural components were reviewed in this study through shake table tests considering long-period ground motions.

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.

This paper is an architectural historical study on Chimi of Hwangnyongsa Temple. In this research, the shape and cross-section of the chimi are reviewed. The results of the study are as follows. The chimi is a form in which the head part facing the maru is omitted, and the upper and lower body are separated. The upper and lower bonds are assembled into a two types of joint throughout the side of the torso, and then bound with an iron strap. Because of the absence of ridge line in the front, and the narrow curved surface which makes the side plate close to the plane, the entire cross-section is triangular, and the rear plate maintains the shape of the chimi. The naerimmaru connected to the side of the chimi has a slope, so it is clear that the chimi was used on the woojingak-jibung(hipped-roof), and the wing part and back of the chimi are erected on the side roof. The height of the yongmaru and chunyeomaru is about the same and the roofing tiles of those are in contact. The roofing tiles of chunyemaru should be cut to fit the angle of the contacting part. The maru is 30 stories high of roofing tiles as a result of the on-board survey. Based on reference on the shape and timing of the production of chimi, the height of chimi, and the maru is believed to have been built before the Unified Silla Period and used in buildings with at least seven-kan frontage. Buildings corresponding to these construction conditions can be seen as Central hall and East hall in Hwangnyongsa temple.

The purpose of this research is to understand Ko Yu-seop’s perception of ‘contemporary emerging architecture’ in the West by investigating into his two early 1930s’ articles: ‘On Emerging Arts, Particularly the Cutting-edge Architecture’ (Jan. 1931) and ‘Russian Architecture’ (Dec. 1932). As a result of the investigation, it is argued that he attempted to systematically describe his contemporary architecture, from the concept of ‘modern’ to representative architectural theories, and his suggested reference list is considered meaningful since it illustrates one aspect of how modern architectural knowledge was transferred to Korea at that time. As his limitation, however, it should be pointed out that a significant part of his writing was a verbatim translation of the Japanese critic Takao Itagaki’s New Art Acquisition (1930). Nevertheless, the two articles give us a valuable understanding related to his socialist tendency, his preferred commune-type city-cum-architecture that reflects the ideology, etc. Hereafter, this understanding needs to be further discussed in both study areas of art history and architectural history in Korea.
