  • 서울시는 도시에서 발생하는 다양한 문제를 해결하고 대시민 서비스 등을 위해 디지털트윈 기반의 도시 공간정보를 구축 및 운영하고 있다. 이러한 디지털트윈 도시 구현을 위한 공간정보의 안정적인 활용을 보장하기 위한 필수요소 2가지는 자료의 최신성과 품질이다. 그러나 높은 품질의 도시 공간정보에 대해 지속적인 최신성을 유지하는 것은 많은 시간과 비용이 필요하다. 이를 극복하기 위하여 효율적인 도시 공간정보 구축 기술과 구축 데이터의 운영, 관리 및 갱신 절차를 연구하였다. 우선, 최신 하이브리드센서를 활용한 포인트 클라우드 중심의 자동 3차원 건물 제작 기술을 실증하여 적용하였고, 고점밀도 항공라이다 성과를 이용하여 수준 높은 건물 모델을 자동제작이 가능함을 확인하였으며, 효율적인 데이터 관리 방안을 수립하였다. 지역별 차별화된 제작 방법의 적용, 공간 객체 고유 관리번호를 통한 도시 변화지역 탐지 지원하고, 수준별 국제표준자료 제작으로 도시 공간정보의 활용성을 강화하였다. 본 연구를 통해 디지털트윈 기반의 도시 공간정보 활성화를 고민하는 지방자치단체 및 관련 기관의 사업 추진에 좋은 선례가 될 수 있을 것으로 판단되며, 도시 단위 디지털트윈 구현의 인프라 정보로써 공간정보의 구축 및 관리에 대한 논의가 지속적으로 이루어 질 것을 기대한다.

  • This study is about Yoo Young-kuk's early works which show constructivism, especially focus on his debut painting, for the 7th Dokuritsu Bijutsu Kyokai(獨立美術協會, the Independent Fine Arts Association) in Tokyo in 1937. The work was painted 2 years after he had started his study in Japan in 1935. It was the first painting that applied Constructivism. played an important role for Constructivism to be a leading art in his abstraction. After this picture, Yoo was soon devoted to the principles of Constructivism-- Faktura(material), Tektonika (tectonics), Tekhnika(technique), space, construction-- in his painterly reliefs. This article examined why Yoo concentrated on Constructivism for , what the characteristics were, and what influences were on other works from 1935 to 1949. In addition, I investigated in which period was painted and how Constructivism was spread in 1930s and early 1940s in chapter 2. I scrutinized Rhapsody in chapter 3. When Yoo created Japan was under the Fifteen Years War(1931-1945), and a major discourse was the Japanese Spirit at that time. It was connected with construction of an ideal nation which the Japanese ultra-national fascism pursued. This ideological pursuit was intended to unite the Japanese people for total war system and to restore a national dignity which had been fallen down due to Manchurian Incident(1931). Thus, on the hand, Kokusai Bunka Shinkokai(國際文化振興, The Society for International Cultural Relations) and the Nippon Kosaku Bunka Renmei(日本工作文化連盟, Japanese Werkbund) were supported financially by the Japanese government. On the other hand, the government enacted regulations to opposing parties which would distract Japanese people's unification. As for the Japanese art world, the merge of art groups was carried out through remodeling of Teikoku Bijutsuin(帝國美術院, The Imperial Fine Arts Academy) in 1935. This brought out continuous dispute and disorder. Young artists who felt difficulty of entering an entry of Imperial Fine Arts Exhibition repeatedly grouped and disbanded for small art groups to build their standing, which they pursued Surrealism and Abstract art. Among them Constructivism was considered as the latest trend and was popular in craft, design, architecture as well as fine arts. In the year before he painted , Avant-garde theatres including Constructivism theatre were introduced in a feature article of September, 1936 in Atelier, which was dealing with mainly avant-garde arts. Books related with Constructivism were translated into Japanese, and Gestaltung Education had become active since the publication of A Compendium of Gestaltung Education("構成敎育大系"(1934)), Salvador Dali(1904-1989) was also introduced, so Surrealism was drawn more attention by young artists. reflected popular trends. Yoo analyzed the Japanese avant-gardists' archaic taste in the Independent Art Association that he submitted his painting to. And then he entitled 'Rhapsody' which derives from Ancient Greek's epic poetry and deliberately set up images in a scene. In chapter 3, I examined a theme which was planned carefully by sorting favorite images from the Japanese Surrealism. was a result that Yoo Young-kuk observed objectively the phenomenon that young artists dreamt of Utopia or longed for Nostalgia passively and lethargically under wars. And then he otherized himself from that circumstance. First of all, for he used the typical icons of Japanese Surrealism such as the horizon, flowing clouds, and vast plain that were considered stereotypes of Arcadia. He, however distinguished himself form those Japanese Surrealists. He made his own vision about Utopia by referring Lyubov Popova(1889-1924)'s stage design. His objective point of view was expressed by positive and dynamic images of structure and human's actions. Constructivism which was attempted in had an effect on other early constructive works, and the principles of Constructivism were sought hard in reliefs, paintings, and photos.

  • The study was to estimate the effect of the rise of water temperature in the warm water pool and to make contribution to the establishment of reducing to a damage of cool water as well as to the planning for warm water pool. This observation was performed in Wudu warm water pool located at Wudu-Dong of Chuncheon for two years from 1975 to 1976. The results were showed as follows; 1. The daily variation of water temperature was the least for inset (No.1; 0.6$^{\circ}C$) the second for middle overflow (No2: 3$^{\circ}C$, No.3; 2.3$^{\circ}C$) and another for outflet (No.4; 3.6$^{\circ}C$, No.5; 3.8$^{\circ}C$) And the highest reaching time of water temperature in each block was later about 1 hour than the time at which air temperature happend in the daytime. So, the variation of water temperature was sensitive to the variation of air temperature 2. The monthly variation of water temperature at each measuring point was plotted to be increased with increase in air temperature till August (Mean monthly rising degree; No.1; 1.15$^{\circ}C$, No.2; 1.7$^{\circ}C$, No.3; 1.73$^{\circ}C$, No.4; 2.08$^{\circ}C$, No.5; 2.0$^{\circ}C$), and expressed gradually descended influence upon water temperature after August. 3. The mean temperature of inflow folwed in warm Water pool was 7.5∼12.5$^{\circ}C$, and outflow temperature was described as 13.4∼22.5$^{\circ}C$ to be climbed. And So, the rising interval of water temperature was shown as 6.7∼10.4$^{\circ}C$. 4. The correlation between the rising of water temperature and the weather condition was found out highly significant. As the result, their correlation coefficents of water temperature depending on mean air temperature, ground temperature, wind velocity and relative humidity were to be 0.93, 0.90, - 0.83 and 0.71 respectively. But there was no confrimation of the correlation on the clouds, sunlight time, volume of evaporation, and heat capacity of horizontal place. 5. The water temperature of balance during the period of rice growing in Chuncheon district was shown as table 10, and the mean of whole period was calculated as about 23.7$^{\circ}C$. 6. The observed value of the outflow temperature passed through the warm water pool was higher than that of computed, the mean difference between two value was marked as 1.15$^{\circ}C$ for blockl, 1.18$^{\circ}C$ for block2, and 0.47$^{\circ}C$ for block3, respectivly. Therefore, the ratio on the rising degree between the observed and computed were shown as 53%, 44%, and 18%, mean 38% through each block warm water pool (referring item $\circled9$ of table 11,12, and 13). Accordingly, formula (4) in order to fit for each block warm water pool was transfromed as follow; {{{{ { theta }_{w } - { theta }_{ 0} =[1-exp LEFT { { 1-(1+2 varphi )} over {cp } CDOT { A} over { q} RIGHT } ] TIMES ( { theta }_{w } - { theta }_{ 0}) TIMES C }}}} Here, correction coefficinent was computed 1.38, and being substituted 1.38 for C in preceding formula, the expected water temperature will be calculated to be able to irrigate the rice paddy. As the result, we can apply the coefficient in order to plan and to construct a new warm water pool.

  • 18세기 전반 북경에서 형성된 사왕산수화풍은 19세기에 한국과 일본으로 널리 전파되어 각국의 새로운 시대 화풍을 발전시키는데 중요한 밑거름이 되었다. 이러한 화풍은 청 문사들과 교유했던 신위나 김정희에 의해 본격적으로 전래되기 시작하였고, 그들의 영향을 직간접으로 받았던 신명연, 이한철, 유숙, 장승업, 안중식, 조석진 등이 사왕풍으로 그림을 그리면서 한국 화단의 주요한 화풍으로 자리매김하게 되었다. 이들이 그린 사왕풍 산수화에서 공통으로 보이는 특징은 고원법으로 자연 경물을 가까이에서 포착하고, 화면의 오른쪽이나 왼쪽 하단부에 배치된 키가 큰 나무를 기점으로 계류(溪流)를 건너 주산이 펼쳐지는 것이다. 하지만 최근 공개된 화원화가 안건영이 그린 <산수도> 6폭 병풍은 19세기 후반 유행했던 사왕풍을 근간으로 하면서도 경물포착이나 필법 및 색채감각 등에서 이들과는 차별화된 면모를 보여주고 있어 주목된다. 안건영의 현전 작품들은 대개 소품인데 이 병풍은 6폭의 산수화로 꾸며진 대작에 해당된다. 특히 산수의 여러 경관을 윤묵(潤墨)의 가는 필선으로 섬세하게 묘사하여 고요하면서도 차분한 분위기를 조성한 것이라든지 일부 화폭에서 조감법(鳥瞰法)으로 경물을 포착하여 거시적인 시점을 보여주는 것, 연운(煙雲)을 통해 화면에 생동감을 부여하는 것 등에서 새로운 면모를 읽을 수 있다. 이러한 화풍은 19세기 전반 강남(江南) 화단에서 사왕풍을 근간으로 하면서도 중국의 실제 명산을 돌아다니며 익힌 사생(寫生)을 절충하며 산수의 기운이나 생명력을 전달하려고 했던 왕학호, 탕이분, 대희 등의 화풍과 연관이 있는 것으로 판단된다. 따라서 안건영의 <산수도> 6폭 병풍은 19세기에 북경 화단과는 차별화된 양상을 나타냈던 강남 화단의 사왕산수화풍이 전래 수용되었다는 사실을 알려주는 보기 드문 사례로 중요하다고 할 수 있다.
