Korean temple gardens have very high preservation value as the place reflecting ancestral wisdom in harmony with nature. Not only as a religious place but also as a beautiful landscape place, many people including foreigners are visiting traditional Korean temples. However, current many Korean temple gardens lost their original value and meaning because of the inappropriate planting in traditional places. In this study, for maintaining the representativeness of traditional Korean temple, we researched the current planting status of traditional Korean temple. After the research of 51 traditional Korean temples, a total of 207 species of plants was investigated, and among them 128 species (61.84%) were Korean native plants, 76 species (36.71%) were cultivar plants, 2 species (0.97%) were naturalized plants, and 1 species (0.48%) is introduced plant. Korean red pine (46 temples), sawleaf zelkova (38 temples), and ginkgo (36 temples) were the high rank species among 207 species. Korean rare plants including black-fruit hackberry and Korean fir form 5.3% of total species, and Korean endemic plants including Korean weigela and Korean paulownia form 3.4% of total species in traditional Korean temples. On the other hand, plants that have religious meaning such as lotus, musa, and guelder rose form slightly. There is a higher proportion of traditional Korean plants than religious meaning plants in traditional temple gardens, so that temple gardens are highlighted as historic places. Based on the planting status, maintenance plans were established reflecting characteristics of each spaces: entry space, the precincts of a shrine, and flower stairs. As a result, we suggest that selecting a suitable plant species with regard to the religious meaning of the plant symbolism for newly designing Korean temple gardens.

그간 무궁화 보급운동은 무궁화가 가지고 있는 속성과 품종의 선택, 식재방법 및 관리에 대한 기본 개념이 정립되지 않은 상태에서 추진되어온 결과 다소 잘못된 점이 도출 되었을 뿐 아니라 국민들이 좋아할 만큼 성공되지 못하였다. 세계적으로 무궁화를 가로수나 정원수로 심고 있는 나라는 온대지역에 속하는 대부분의 나라로 알려져 있고 특히 그리스나 이태리에서 주택가나 가로수로 식재되고 있다. 그러나 그 가로수는 우리가 일반적으로 생각하고 있는 느티나무, 은행나무, 버드나무등과 같이 크게 자라는 나무가 아니므로 주택가나 꽃길조성에 식재되어 왔다. 이제 무궁화는 어느 곳이든 잘 자라는 수벽이나 꽃동산으로 이용하고 아무데서나 잘 자란다는 「고정관념」을 버려야 한다.

We have measured ${\pi}^*$, $\alpha$ and $\beta$ polarity parameters of 2-propanol / hexane and ethyl acetate / hexane mixed solvents over the entire range of composition. For the ethyl acetate / hexane system, only ${\pi}^*$ and $\beta$ were measured since $\alpha$ of these mixed solvents are defined zero. We have corrected the measured polarity parameters to obtain consistent data with the existing literature data assuming a good linear correlation between the measured and the true values. The variation patterns are consistent with the expected trends based on the chemistry of the solvent components. The general trends of the two solvent systems are summarized as follows. ${\pi}^*$ merely increases as the content of the more polar solvent increases while $\alpha$ and $\beta$ increase with the increase of the content of the more polar solvent, then decrease upon continuing addition of the more polar solvent.

태양전지, 터치센서와 같이 투명한 전극(TCO: Transparent conducting oxide)이 필요로 하는 곳에는 금속 산화물 형태의 ITO, ZnO, FTO와 같은 투명 전극이 사용된다. 그중에서 FTO는 저렴한 가격과 높은 투과율, 낮은 저항으로 주목을 받고 있다. 뿐만아니라 FTO 박막은 다른 산화물 전도체에 비해 구부림에 강한 저항성을 보여 주고 있다. FTO 박막의 캐리어 전하 생성 원리는 F 원자가 O 원자의 자리를 치환하게 되면서 잉여 전자의 발생으로 전기가 흐를 수 있다. 아직까지는 화학적 조성비에 유리한 CVD를 이용한 증착 방법이 많이 사용되고 있다. 스퍼터 장비 역시 공정 가스에 따라 화학적 조성비 변화가 가능하고 CVD와 비교하여 공정이 간단하며 연속 공정이 쉽고 대면적 적용이 가능하다. 본 실험은 본사에서 R&D용으로 제작한 Daon-1000 S 장비를 사용하였으며 DaON-1000 S는 3개의 2" sputter gun이 장착 되어 있어 co-sputtering이 가능한 장비이다.

기후변화 및 도시열섬화 등의 영향으로 여름철 폭염 및 봄·겨울철 미세먼지 영향은 증가하고 있다. 최근 40년(1980년~2019년) 동안 서울의 최고기온은 2.2℃ 증가하였으며, 이는 전국에서 두 번째로 높은 증가추세이다. 서울시는 도시열섬과 미세먼지 저감을 일환으로 '스마트 물순환도시 조성사업'을 추진하고 있다. 본 연구에서는 서울형 물순환도시 소개와 더불어 쿨링포그, 쿨루프, 클린로드시스템, 투수블록, 식생수로 빗물정원 등 수자원을 활용한 기술을 조사하고 문헌조사를 통해 저감효과를 비교분석하였다. 이는 수자원을 활용한 도시 형태 개선으로 쾌적한 도시환경 조성 뿐만 아니라 시민의 행복과 만족감 증대에 기여할 것으로 판단되며, 향후 서울형 스마트 물순환도시 보다 많은 지역에 확대운영 할 수 되도록 기여하고자 한다.

The vertical garden is an environment where plants have many limitations in their growth. In particular, the upper and lower parts of the foundation are characterized by unbalanced moisture distribution. And although it may vary depending on the installation location of the light, generally the base of the light is not in desperate need for plants to grow due to shade. The purpose of this study was to identify the physical characteristics of the vertical garden based on Felt through experiments, classify the location characteristics of the media, and suggest the method of installing the water quantity water frequency, and lighting according to the location characteristics of the foundation. As a result, it was found to be most appropriate to use a 4mm base for the vertical garden and to have an irrigation of about 10 minutes once every 6 hours. In addition, it was found that in order to create a light condition for sufficient growth of plants, light bulbs should be installed at the upper and lower parts of the foundation. As a result of irrigation and lighting tests, the results of the above-mentioned plants need to be referred to in selecting plants that are introduced to vertical gardens, as the results show that the upper part of the foundation has a lower moisture rate and a stronger light than the lower part, and the lower part has a higher moisture rate and a weaker light than the upper part. In the future, we would like to present more accurate methods of selecting and maintaining plants by conducting plant experiments using the underlying characteristics found in this study.

This study is the research about Okcheonjeong(玉泉亭) located in the backyard of Namhansanseong(南漢山城)'s temporary palace(行宮). Okcheonjeong was not only built by a government inside Namhansanseong but it was also representative garden which is shown the culture of the nobility. It became famous garden ruins recently because it has remained many carved stones. However, there has been no study about Okcheonjeong yet. We studied Okcheonjeong to establish basic knowledge by literature analysis and field investigation. We tried to discover garden style by deciphering carved stones, and estimate Okcheonjeong's location by documentary research. Sim, Sang-Gyu became Gwangjuyusu(廣州留守) in 1816, and he built Okcheonjeong on the backyard of Namhansanseong's temporary palace in 1817. It was located in the foot of a mountain beside a stream. It consisted of Pungaepok(楓靄瀑: waterfall), Chusudam(秋水潭: a little pond), and Okcheon(玉泉: a stone wall). The stone for sign stands in front of the entrance of Pungaepok to show Okcheonjeong, and there is Yeongyeondae(泠然臺) above the waterfall. We thought that Okcheonjeong was typical Imcheon-garden(林泉庭苑). Okcheonjeong is located in the foot of a mountain following Gamigyeong(歌薇逕) 60 meters so it was able to see the whole temporary palace from the Okcheonjeong. It was the garden pavilion of temporary palace, but it was used in semi public garden(半公的庭苑). Okcheonjeong is the only graden ruins which was located in Namhansanseong, so we have to preserve as cultural heritage. We expect to make use of primary datas to restore Namhansanseong soundly which was world heritage.

The Sin-Wol filtration plant was an urban infrastructure and off-limits to the public. It is recreated as a representative experiential theme park in the southwest area. It has not only provided places to relax, but has made a new model of urban park by reusing advantages. The current lack of easy access into the park area almost isolates it like a green island. The neighborhood surrounding the park does not have many physical connections to the park to be able to use it. By connecting the surrounding communities with numerous access points into the park and linking the hiking trails and bike paths, the city's need for open space and recreation would be far better satisfied than before. This would allow for the use of the valuable assets of the existing forest and open space.
