The adaptive reuse of 20th-century high-rise architecture poses important questions about the prevalence of authorized discourses in the heritage conservation field. Based on a two-year teaching experience at Tongji University about the adaptive reuse of the Metropolo Hotel (Palmer and Turner, 1934), an iconic historic high-rise building in the Shanghai Bund area, this paper will show the extent to which disciplinary and urban authorized heritage discourses are present in the development of design and representation strategies in adaptive reuse. Using discourse analysis as a method, this paper will make the argument that disciplinary discourses have a limited effect in the practice of adaptive reuse, which is perceived as a fundamentally creative activity. At the same time, the paper reveals how urban discourses have a much more lasting effect, confirming the intimate links between adaptive reuse and the wider phenomena of beautification and gentrification of high-rise listed areas.

In the past decade, experts have conducted parasitological research on archaeological specimens in Korea to collect historical parasite infection data. In these studies, parasitologists successfully described the infection pattern of each parasite species in history. However, in the first half of the 20th century, archaeoparasitological reports have been scant. In 2021, we conducted a parasitological examination of a toilet-like structure that emerged in the early 20th century. This structure was built by stacking 2 wooden barrels; and in the study samples, we found ancient Trichuris trichiura, Ascaris lumbricoides (unfertilized), and Taenia spp. eggs and therefore proposed a higher possibility that the barrels could have been used as a toilet at the time. To understand how the antihelminthic campaign since the 1960s helped reduce parasite infection rates in Korea, more research should focus on early-20th-century toilet ruins.

Konbaung Dynasty was the last unified dynasty that ruled Myanmar from 18^th to 19^th century. During this time Buddhist art flourished in Myanmar due to the interest of the rulers toward their traditional culture. Metal decorative artifacts in the 18^th century are classified into structures and Buddha statues. They are further subdivided into gilt-bronze and bronze objects, depending on their material component. Three-dimensional gilt-bronze decorative artifacts were cast with a brass alloy of Cu-Zn-Sn-Pb and their surfaces were gilded with extremely thin gold leaves (less than 1 ㎛ in thickness). The gilded layer approximately comprised 10 wt% silver in addition to the main element, gold. The lack of Hg in the gilded layer, indicated that the amalgam gilding technique was not applied. The analysis results indicated that the lacquered gilding technique was applied to the objects. Bronze decorative artifacts without gilding were cast with materials containing Cu-Sn-Pb. The bronze pavilions and bronze Buddha staues were crafted using the same alloy of high-tin bronze, which approximately contained 20 wt% Sn. No heat treatment was applied to reduce the brittleness of the objects after they were cast with a large amount of Sn. The most significant difference between the gilt-bronze and bronze decorative artifacts lie in their elemental compositions. The gilt-bronze decorative artifacts with their gilded surface were manufactured using brass containing zinc, while the unplated bronze decorative artifacts were composed of bronze containing tin. Artifacts of the same type and size are classified differently depending on the materials utilized in the surface treatment such as gilding.

Through a combination of scientific analytical methods, the coloring materials used in $20^{th}$ century paintings in historical churches of Baclayon, Dauis and Loay, which are municipalities in Bohol, Philippines, were studied. Inorganic pigments were identified using SEM-EDS and XRD. Iron-based pigments were commonly found in the paintings, yielding dark yellow and brown colors. Zinc oxide was identified as the white pigment in the ceiling paintings of Dauis Church and Loay Church, while titanium dioxide was detected in the column painting in Baclayon Church. Organic analysis showed the presence of Pigment Yellow 3, a synthetic organic pigment. Paint layers, as well as other components of the samples such as grounds and metal leaves, were examined microscopically. It was observed that different types of grounds were applied on different types of surfaces. Moreover, organic pigments were found in combination with white extender materials. Microscopic examination also revealed alterations in the artworks, such as the overpaint layer found in the samples from Baclayon Church cornice and the imitation metal leaf layers applied over the original gilt surface in the Loay Church retablo.

문화재 인식의 출발점이 되는 문화재 '선택'에는 당시 지배 권력의 문화적 이데올로기가 반영된다는 가정을 세웠고, 이를 20세기 한국의 사례를 통해 증명하였다. 먼저 대한제국 후기(1901~1910)에는 조선시대부터 가져오던 과거 유적들에 대한 관점을 거의 유지하고 있었다. 국가가 중요하게 보호하려 한 대상은 왕릉과 왕실기록물들이었다. 이 시기에 한국 유적들에 대한 일본인들의 조사가 본격적으로 시작되었고, 이에 자극받은 계몽주의 지식인들에 의한 주체적 문화재 인식 시도가 있었으나 제도화되지 못하였다. 일제강점기(1910~1945)에는 일본인들 주도로 문화재 조사와 제도화가 진행되었고, 이는 현재 한국 문화재 관리체계의 출발점이 되었다. 당시 조선총독부가 주도한 고적 조사, 지정, 보호, 선양 활동은 일본 제국주의 지배를 합리화함과 동시에 식민주의 사관을 반영하는 것들이었다. 국내 민족주의자들이 계몽적 차원에서 고적애호 운동을 벌였으나, 이는 일본인들이 기획한 고적조사 성과에 기초하였다는 한계가 있었다. 해방 후(1945~2000)에는 민족주의 이데올로기에 기반하여 문화재 복구와 복원 활동들이 있었고, 여기에도 정권의 정통성을 공고히 하려는 의도가 내포되었다. 그리고 1997년의 '문화유산 헌장' 제정은 문화재가 민족주의 이데올로기의 수단이 되는 것을 넘어 그 자체로 이데올로기가 되는 일이었다. 지난 20세기 동안 한국에서는 정치권력의 선택에 따라 문화재의 내용이 변하였다. 이 선택에는 당시 권력이 문화재에 대해 가지는 문화적인 이데올로기가 반영되었다. 이런 문화재 선택의 배경에는 개념어와 사회의 상호 보완적 관계, 즉 집합기억의 이데올로기적 특성이 작용하고 있었다. 지배집단은 그들의 이데올로기를 피지배집단에 각인시키려 하는데, 그 수단으로 정권의 정통성을 인식시킬 수 있는 전통문화에 관련된 집합기억, 즉 문화재 선정과 활용에 관여함으로써 이를 실현하려고 했다고 볼 수 있다.

The Choijin Lama Temple is a representative example of 19th- to 20th-century architecture. The temple has been damaged by various development pressures and the effect of a harsh continental climate. This study digitalized the entire temple site using three-dimensional scanning to establish the basic data of conservational management and monitoring for spatial changes. A terrestrial laser scanning model of the temple was completed, which showed low registering error vectors (3.73 mm average) and dense point distances. Unmanned aerial vehicle (UAV) photogrammetry was also applied to verify its applicability to the spatial and environmental monitoring of the temple. The results showed that the overall point density of the UAV photogrammetry model is similar within a 10 mm resolution. The relatively low RMSE of UAV photogrammetry from the ground to the uppermost roof indicates the high applicability of integrating it with the terrestrial laser scanning model. The digital documentation of the Choijin Lama Temple is expected to have a great ripple effect on the documentation, conservation, and utilization of Mongolian cultural heritage sites.

The $18^{th}$ century's Industrial Revolution brought about influx of commerce, industry, and agricultural population into the urban areas, entering the $19^{th}$ century. Quality of rural communities declined, and the exploding population in the cities gave rise to various problems. 'Mietskaserne' Blockhousing was constructed by the 'Hobrechtplan', but led to social problems such as poor living conditions, insufficient sunshine due to overcrowding, slums due to incomplete urban infrastructure, epidemics, and so on. Starting in the early $20^{th}$ century, Berlin has driven forward a remodeling plan under the motto of 'critical reconstruction (kritische Rekonstruktion)'. It is performed in the place, which represents the vicissitudinous history of Berlin with site plans coexisting past with presence, using modern vocabulary of architectural forms. Reconstructing a city is a process which not only raises the economic value of each building consisting a city, but also a redevelopment process that brings out cultural value of an era. When a new era emerges buildings get reconstructed or rebuilt, and thereby form the identity of a city by reflecting its society, culture, politics, economy, and history. Old German architecture were not destroyed or rebuilt recklessly just by the fact that they are functionally or aesthetically outdated. Each building is treated as precious cultural heritage reflecting the history. This is how Berlin is being transformed today.

Glass pieces excavated from Mireuksa Temple dated $7^{th}$ century A.D. were characterized by chemical composition, specific gravity and melting point. Lead isotope ratios of lead glasses were also compared with those of lead ore to attribute which lead ore was delivered for making lead glass. It was known that some lead glasses found in Japan were similar with those of Mireuksa Temple as comparing the data of chemical composition and lead isotope ratios. Characteristics of lead glass from Mireuksa Temple Thirty five glass pieces of Mireuksa Temple were analyzed for five oxides and found that all was lead glass system(PbO-$SiO_2$) with the range of 70~79% for PbO and 20~28% for $SiO_2$. The concentrations of oxides such as $Al_2O_3$, $Fe_2O_3$ and CuO were below 0.4%, 0.3% and 0.9%, respectively. Principal component analysis(PCA) as a statistical method was carried out to classify glasses with the similarities of chemical concentrations. The result of PCA has shown that three groups of glasses were created according to the excavation positions and two major oxides(PbO and $SiO_2$) greatly contributed to the dispersion of glasses on principal component 1(PC1) axis and trace element oxides($Al_2O_3$ and $Fe_2O_3$) for PC2 axis. Most of lead glasses were greenish by the efficacy of iron and copper oxides and some showed yellowish-green. The gravity of lead glasses was about 4.4~5.4 and estimated melting point was near $670^{\circ}C$. Lead isotope ratios of glasses were analyzed and found quite close to a lead ore from the Bupyeong mine in Gyeonggi-do. Comparison with lead glasses found in Japan Lead glasses of Mireuksa Temple were compared with those of Japan on the basis of chemical and physical data. Chemical compositions of Japanese lead glasses dated $7^{th}{\sim}8^{th}$ century A.D. were nearly similar with those of Mireuksa Temple but lead isotope ratios of those were separated into two groups. Three distribution maps of lead ores of Korea, Japan and China with lead isotope ratios were applied for lead glasses found in Japan. The result have shown that the locations of lead glasses from Fukuoka Prefecture coincided with the region of northen part of Korea and similar with those of Mireuksa Temple and lead glasses from Nara Prefecture dated $8^{th}$ century A.D. were located in the region of Japanese lead ore. This research has demonstrated that lead glasses of Mireuksa Temple conveyed to Miyajidake site, Fukuoka Prefecture around $7^{th}$ century A.D. and glass melting pots and glass beads excavated from Nara Prefecture confirmed the first use of Japanese lead ore for production of lead glasses from the end of $7^{th}$ century A.D.

The cultural properties of paper made from 11 to 16th century of the Kirimsa temple were found in Birozana Buddhist Statue which was made from 15 to 16th century. These have been stored and exhibited in the exhibition showcase. To examine the environment of conservation and the state of paper, we investigated the temperature and the relative humidity in the inside and outside of the Kirimsa museum and examined the external form and the internal state (water content, acidity and whiteness) of paper. During the investigation period from 27 Aug. to 30 Aug. 1997. The average of temperature and relative humidity were $28.2^{\circ}C$, 67% in the outside and $27.1^{\circ}C$, 73% in the inside, respectively. These indicated the air conditioning was wrong. Among the cultural properties of 79 papers stored in the Kirimsa museum, 37 cases had been repaired but 42 cases not. From the result examining the external form, 20 cases needed to repair. In the internal state of the cultural properties of paper, the water contents were from 11.9% to 16.5%, the average was 15.7%, the acidities from pH 5.7 to pH 6.2 and the whiteness from 37 to 45. From these results, we could see the cultural properties of paper stored in the Kirimsa museum was damaged by the several factors (hydrolysis by fungi, repeated elongation and retraction of cellulose) caused mainly by the high temperature and relative humidity. Therefore, for the conservation of the cultural properties of paper stored in the Kirimsa museum, it need to control the temperature at $18~20^{\circ}C$ and the relative humidity at $55\pm5%$ by the appropriate air conditioning. In order to sterilize fungi occurred to the surface of paper, the cultural properties of paper needed to fumigate. The fungi occurred on the surface of paper were wiped out by using of 70%solution dissolved thymol in ethyl alcohol.
