As interest in the public display of art and outdoor sculptures is increasing, the conservation and treatment of these sculptures is becoming increasingly crucial. Long-term exposure to the natural elements and atmospheric pollution can cause corrosion and deterioration in outdoor sculptures. In the case of Kim Chan Shik's "Feeling", which was exhibited in the outdoor sculpture park at the National Museum of Modern and Contemporary Art (MMCA), the patina of the sculpture was damaged during a long outdoor exhibition. Therefore, the treatment process was as follows: recording of condition, sanding, repatination, and wax coating. Consequently, the sculpture was restored similar to the original. Chemical analysis revealed that the sculpture was crafted from bronze and was cast from a quaternary alloy of Cu-Pb-Sn-Zn. The welding is lower in Zn, Sn, and Pb content than the metal used in the sculpture itself. Bright strains contain about 13.0 wt% Sn and 10.5 wt% Pb. The strains are higher in Sn and Pb content than the rest of the metal in the sculpture (7.0 wt% Sn and 4.4 wt% Pb). As a result of component analysis and microstructure observation, the material is estimated to have been made by casting without artificial treatment.

Waxes currently used as a coating material to preserve surfaces of outdoor iron sculptures tend to face lower coating strength and efflorescence due to the aging from air pollution and acid rains. Consequently, they are subjected to repeated corrosions shortly after the treatment. And the sculptures face the problem losing their original nature because of the changes of colors and lusters, so this convergence study aims at developing wax with better performance than the existing materials. For this reason, the study identified the effects of physical property using the environmental experiments such as the tests of salt spray and gas corrosion as well as the analysis of luster level and thermo-gravimetry. As this study result, the developed ISC wax showed the excellent blocking effect from salt water and coating durability more than five times compared with the existing waxes, better acid resistance by two-four times, sun block effect by 2-10 times, improved luster variance by 3-16 times, improved thermo-stability and durability by 0.5-5 times, and therefore demonstrating far better coating effect than the existing waxes. In the light of these findings, this study contributes for this new development which can replace the existing waxes used so far in order to preserve the outdoor iron sculptures.

This study aimed to examine the characteristics of paint used for modern art works by conducting sectional observations, inorganic component analysis, and infrared spectroscopic analysis on the painted layers of 3 painted sculpture works exhibited in the Yongdam Dam Environmental Sculpture Park and Naejangsan Sculpture Park in the Jeollabuk-do area. The observations indicate that the cross section is composed of various layers of 2-3 folds, the thickness of the layers was uneven at approximately 23-150 ㎛, and putty was used for plate treatment prior to painting. Inorganic component analysis results show that putty containing calcium carbonate, iron oxide, diatomite, and titanium dioxide was used for the putty layer. It is also assumed that paint mixed with green (Cr₂O₃), blue(sodaliteblue), red(chromered), andwhite(TiO₂) colors were used for the painted layers. As a result of infrared spectroscopic analysis to confirm the types of paint, it is estimated that the paint was mixed with polyester resin and an extender.

A study on conservation of outdoor painted sculptures has begun to receive attention as increasing numbers of the sculptures, but it is still in an early stage in South Korea. In the case of a painted outdoor object which has been exhibited in National Museum of Modern and Contemporary Art (MMCA), 'Black nana' produced by Niki de Saint Phalle in 1964, deterioration was observed, such as flaking and discolouration of paint layers due to ultraviolet light and a sudden temperature change during an outdoor exhibition. For this reason, prior to treatment of the sculpture, to find out the painting techniques and materials applied, cross section, FT-IR, Raman and Py-GC/Mass were conducted. As a result, the type and colour of the paint agree with results of the other studies as well as deterioration pattern. It is expected that the results of this study will be utilized for treatment proposal and conservation material selection of 'Black nana'. In addition, to determine the artist's intention of the artist, cooperation with the foundation of Niki de Saint Phalle and artist's assistants will be carried out.

The 88 Olympic Park is a monumental urban park in Seoul, developed to commemorate South Korea's hosting of the 1988 Seoul Olympic Games. Initially conceived to emphasize the event slogan, 'Cultural Olympics,' which was driven by the Korean government, the park, already designed and constructed by 1986, was reconfigured into a sculpture park following two international outdoor sculpture Olympiads and an invitational sculpture exhibition. This study takes a look at the process of redesigning the park into sculpture park and the socio-political discussions surrounding such a process, in order to reconsider the significance of the 88 Seoul Olympic Park with regards to Korean landscape architectural history. Several discussions within Korean society arose during the redesign process. First, there were critiques on the artwork selection during the early phase of the project. Second, issues regarding the conservation of the national heritage site, Mongchon-tosung, located within the park, gave rise to a larger discourse on heritage preservation in Seoul. Third, discussions regarding the formation of the park identity, or lack thereof, prevalent. Through this study, the 88 Seoul Olympic Park presents itself as an example where large park construction in Seoul caused discussions regarding globalization, nationalism, publicness and art to be brought forth. This paper concludes that the 88 Seoul Olympic Park is a cultural landscape that requires further examination and exploration as it provides rich historical context for understanding the history of cultural and artistic practices in Korean urban landscapes.

The occurrence pattern and bionomics of Selatosomus puncticollis (Motschulsky) were surveyed in three net house (6$\times$70m) in the field and in a laboratory ($20^{\circ}C$, RH$75\%$, L16/DB). Emergence of hibernated adults of S. puncricollis started from early May, reached peak at early June and diminished in late June. Occurrence rate to total number was $42.1\%$ in early June and $31.7\%$ in late May, when most of hibernated adults emerged at these periods. Adults started to oviposit from mid June, and eggs hatched from early July Larvae turned into pupae from mid July and emerged to adults from mid August. Egg-period was 23 days and pupal period was 21 days. It is estimated that preovipositional period and larval period were approximately 10 months and 30 months, respectively. Wireworms were distributed at the soil depth of 10-5 cm, $56.8\%$ in 1997 and $45.8\%$ in 1998. To establish bait techniques to attract wireworms in the soil, six baits: pieces of potato, carrot, and sweet potato, wheat grains, corns, and flour dough wrapped with gauze, were buried at 15 cm of soil depth, and collected after 5 and 10 days. The numbers of wireworms attracted by potato pieces, wheat grains and sweet potato pieces after 10 days were 1.8, 1.6, and 1.4/bait, respectively. Therefore, burying potato pieces at 15 cm of soil depth and collected after 10 days could be recommended as a wireworm baiting technique.

The purpose of this study was to analyze the monumental expression of Korean War Memorials(KWM) in Korea(KWMK). Through site survey and internet searching, the researcher selected 17 KWMK and analyzed four analysis categories: contents, spatial form, landscape elements, sculptures and architectural elements. The results are as follows: 1. The analysis revealed that main contents of KWMK were to cherish victims of the Korean War, honor military merit, and explain Korean War. 2. Most KWMK built battlefield had the form of symmetry and spatial axis arranged monuments and sculptures for solemnity and heroism. Though the sites were terraced by traditional spatial order, spatial sequence wasn't seen except Yang-gu KWMK and Chumomyeongbi in United Nations Memorial Cemetery in Korea. 3. Stone monument-like towers, tablets, podium, monoliths, cenotaphs, and exhibit halls to explain Korean War and combat history were used as main elements of KWMK and also, war weapons were often displayed the flags of countries taking part in Korean War were raised with Taegeukgi and the United Nations flag. 4. Most sculptures were used as important media to represent the Korean War and assumed realistically the form of heroic combat. But a few architectural memorial built in recent were designed in contemporary style to have spatial sequence and represent Korean War symbolically and narratively. 5. In memorial culture, KWMK were strongly influenced by ideology and patriotism, impacted by conventional value, and designed by some sculptors and designers in a certain circle. Further study will be required to analyze the characteristics of KWMK in the point of design style and diachronic.

The National Museum of Korea Conservation science division conducted a precise diagnosis and a non-destructive investigation to comprehensively assess the overall damage of the Twin-lion stone lantern from the Godalsa Temple site, Yeoju to be placed on display in the museum's outdoor stone garden, then reviewed the relevant conservation and management plan and applied conservation treatment to the artifact. The museum carried out the treatment in the following order: precise diagnosis; dismantling of the previously-restored part of the roof stone; reinforcement and restoration of the roof structure with new stone; restoration of the previously-restored part of the lantern's support stone (jungseok); surface texture treatment to the restored area; cleaning (basic, laser); and color matching. The previously-restored part of the roof stone was removed and restored with new stone material, based on the results of a safety diagnosis regarding the separation at the said part. Granite from the Sangju area was selected as the material for the restoration in consideration of the results of mineral analysis as well as the surface color and particle size. The new stone was divided into three pieces based on the descending edges of the octagonal roof structure and joined together using epoxy resin. The structure was further strengthened by inserting titanium rods. It is expected that the status diagnosis and conservation treatment of the twin-lion stone lantern from the Godalsa Temple site in Yeoju will be used as a reference for the future conservation and management of outdoor displays of stone cultural heritage.

Neulgeori prehistoric site is located at Joong-ri Kwanin-myon Pocheon-si, Gyeonggi-do, where lots of stone artefacts were excavated. We investigated the petrological features of the artefacts through petrographical observation and modal analysis. In addition we estimated the provenance of the artefacts by means of the geological survey. The twelve stone artefacts used in this study are identified as ash tuff, lapilli tuff, granite porphyry, andesite and diorite porphyry. Various rocks were used for making flakes, whereas blades and debris were from the tuffaceous rocks. Lapilli tuff is considered to have been delivered from the Dongmakgol tuff in the Cheolwon basin, granite porphyry from the Cretaceous granite porphyry stocks cropped out at the southeastern Oksan-ri and eastern Yeoncheon areas. Andesite artefact would have been originated from the outcrops located at the northern part of the site, and diorite porphyry artefact from the southern part of the site. The stone artefacts investigated are estimated to have been transported from the area within 15 kilometers from the site.

The tracksite of dinosaurs and pterosaurs in Sanbuk-dong of Gunsan is the largest early Cretaceous dinosaur footprint fossil site in Korea, and all the footprints are important evidence indicating that large ornithopod and theropod dinosaurs inhabited the Korean peninsula during the early Cretaceous. The Sanbuk-dong site was covered with waterproof sheet in an outdoor environment until the installation of a protective enclosure in 2021. As a result, various factors such as shear force, load reduction, temperature and humidity fluctuations, acid rain, salinity and microorganisms have complexly interacted in the substrate of fossils, exacerbating the damage to footprints. For 159 footprints in 12 trackways among the footprints found in the site, the damage types were classified in detail and the level of each damage was assessed. The damages were classified into 6 types through the classification of deterioration degree of individual footprints. As a result of ultrasonic physical property evaluation on the surface of the fossil site, most of these footprints are in the completely weathered (CW) stage. Furthermore, various weathering patterns were observed in the study area, and surface contaminants were analyzed along the stratigraphy. Although the patterns of freshness and contaminants varied at different points within the fossil site, the chemical compositions were similar. Based on the results, an efficient conservation management system for dinosaur footprint fossils was established, and a conservation treatment type for each footprint was proposed.
