이인성,김형묵,Lee, In-Sung,Kim, Hyoung-Mook 대한흉부심장혈관외과학회 1977 Journal of Chest Surgery (J Chest Surg) Vol.10 No.2

There appears to be significant problems remained in the treatment of thoracic empyema inspire of the more potent broad spectrum antimicrobial agents available and improved surgical managements. Clinical analysis of 60 patients of thoracic empyema was done who received major and/or minor surgical intervention at the Dept. of Thoracic and Cardiovascular Surgery, Korea University Hospital in the period of 3 years from May 1973 to July 1976. Following was the results: 1. Male was predominent to female with the ratio of 2.16 to 1, and adult to infant was 2.75: 1. 2. Most frequent predisposing factors of thoracic empyema in infancy and childhood was pneumonia [38.3%], and in adult was pulmonary tuberculosis [36.7%]. 3. Cardinal symptoms were dyspnea, fever, chest pain and productive cough etc. 4. Positive result of bacteriological culture study was reported in 26. 7%, and among them, Staph. aureus [10%], Diplo. pneumonia [3.3%], Streptococcal group [1.7%], Pseu. aeruginosa [1.7%], Paracolon bacilli [1.7%] and others [8.3%] in respectively. No growth of pathologic organism was reported in 60.0%, and not requested in 13.3%. Among the negative group, tuberculosis was confirmed on pathological tissue slide in half and other half was not determined bacteriologically and pathologically. 5. Surgical treatment was performed to the almost all of the patients with closed thoracostomy [48.3%], empyemectomy [28.3%], empyemectomy with pulmonary resection [11.7%] and others [I1.6%] in respectively with favorable results. 6. Mortality rate was 8.3% [5 cases], each one with lung cancer, diabetes mellitus, respiratory insufficiency, sepsis and another, two months old infant with asphyxia.

원발성 종격동 정상피종: 1례 보고

이인성,김형묵,Lee, In-Sung,Kim, Hyoun-Mook 대한흉부심장혈관외과학회 1978 Journal of Chest Surgery (J Chest Surg) Vol.11 No.2

A case of mediastinal seminoma is presented. A male driver, 27 years old Korean, has been suffered from substernal pain, cough and moderate swallowing difficulty since 5 months prior to this admission. At the time of onset, he visited at a local clinic to find some mass in his anterior mediastinum on chest P-A and lateral X-ray check. Recently, intermittent hiccups with much aggravated dysphagia forced him to visit our hospital, and admitted for radical resection under the impression of anterior superior mediastinal tumor of thymus origin. Median sternotomy was done and total resection of the tumor of 8.0X11.0X3.5cm was done without any specific complication and biopsy of the tumor revealed as primary mediastinal seminoma of the mediastinum. Supplementary prophylactic irradiation therapy was done with a tumor dose of 4,000 rad in 4 weeks after operation. Postoperative hospital course was uneventful and patient was joyful with his occupation for 3 months after discharge.

이인성,박희인,Lee, In Sung,Park, Hee-In The Korean Society of Economic and Environmental G 1982 자원환경지질 Vol.15 No.1

월악 중석-몰리브덴 광상은 옥천충군에 속하는 함력석회질 호온펠스, 호온펠스 그리고 이를 관입한 백악기의 화강암내에 발달한 주향 $NS-N20^{\circ}W$, 수직에 가까운 경사의 열극을 충전한 항중석-몰리브덴 석영맥이다. 광산의 채광장은 서쪽의 동산지구와 동쪽의 광천지구로 나누어져 있다. 두 지구에서 산출되는 광석광물은 철망간중석, 회중석, 휘수연석, 창연, 휘창연석, 황철석, 유비철석 황동석, 큐바나이트, 스태나이트, 자류철석, 섬아연석, 방연석, 백철석, 티단철석, Pb-Bi sulfosalt이다. 맥석 광물로는 석영, 방해석, 녹주석, 형석, 백운모, 능망간석 및 능철석이 산출된다. 유체포유물 연구는 석영, 녹주석, 희중석, 초기의 형석 그리고 말기의 형석을 그 대상으로 하였다. 액체 $CO_2$를 포함하는 포유물은 석영과 초기의 형석에서만 발견된다. 동산지구에서 유체포유물의 염농도는 석영에서 3.9~8.0wt.% 녹주석에서 5.3~7.7wt.%의 범위이며, 광화작용의 말기에 정출한 형석에서는 1.5~3.2wt.%의 범위이다. 광천지구에서의 염농도는 석영에서 3.9~9.6wt.%, 초기의 형석에서 2.9~7.3wt.%, 말기의 형석에서 1.3~1.5wt.%의 범위를 가진다. 유체포유물의 균일화온도는 동산지구의 석영에서 $239^{\circ}{\sim}360^{\circ}C$ 이상, 회중석에서 $360^{\circ}C$ 이상, 녹주석에서 $288^{\circ}{\sim}360^{\circ}C$이상, 말기의 형석에서는 $159^{\circ}{\sim}202^{\circ}C$의 범위를 갖는다. 광천지구에 있어서 유체포유물의 균일화 온도는 석영에서 $240^{\circ}{\sim}360^{\circ}C$ 이상, 초기의 형석에서는 $240^{\circ}{\sim}328^{\circ}C$의 범위이다. 전체적으로 보아 동산지구나 광천지구간에 뚜렷한 광물이나 염농도, 균일화 온도의 차이는 나타나지 않는다. 양지역에 있어서 노두에서 수직으로 약 300m 깊이까지에 걸쳐 상하간에 균일화 온도의 차이는 보이지 않으나 염농도는 하부로 갈수록 약간 증가하는 경향을 보인다. 광화유체는 석영, 녹주석, 초기의 형석등이 정출한 광화작용의 비교적 초기단계에 있어서는 $CO_2$ 농도, 온도와 염농도가 높았으나 말기의 형석의 정출시기에는 $CO_2$ 농도, 온도와 염농도가 현저히 낮아진 것으로 보인다. The Wolak tungsten-molybdenum deposits are tungsten-molybdenum bearing quartz veins which filled the fractures in Pre-Cambrian pebble-bearing calcareous hornfels, hornfels and Cretaceous granite. There are two vein groups in this mine, Dongsan vein group in the west and Kwangcheon vein group in the east. The ore minerals are wolframite, scheelite, molybdenite, native bismuth, bismuthinite, pyrite, arsenopyrite, chalcopyrite, cubanite, stannite, pyrrhotite, sphalerite, galena, marcasite, Pb-Bi sulfosalt and ilmenite. Quartz, calcite, beryl, fluorite, muscovite, rhodochrosite and siderite are gangue minerals. Fluid inclusion studies were carried out for the quartz, beryl, scheelite, early and late fluorite. Fluid inclusion studies reveal that liquid-gas inclusions are most common and occur in all of the minerals examined. Filling degree of the inclusions in the late fluorite is much higher than that of the inclusions in quartz and early fluorite. Liquid $CO_2$ bearing liquid-gas inclusions occur in quartz and early fluorite. Liquid, gas and solid phase inclusions occur in quartz, beryl and scheelite. Salinities of inclusions in quartz and beryl from Dongsan vein group range from 3.9 to 8.0, from 5.3 to 7.7 wt.% NaCl equivalent respectively. Salinities in the late fluorite range from 1.5 to 3.2 wt.% NaCl equivalent. In Kwangcheon vein group salinities range from 3.9 to 9.6 wt.% NaCl equivalent in quartz, from 2.8 to 7.3 wt.% NaCl equivalent in early fluorite, from 1.3 to 1.5 wt.% NaCl equivalent in late fluorite. Homogenization temperatures of inclusions range from $239^{\circ}$ to higher than $360^{\circ}C$ in quartz, over $360^{\circ}C$ in scheelite, from $288^{\circ}C$ to higher than $360^{\circ}C$ in beryl, and from $159^{\circ}$ to $202^{\circ}C$ in late fluorite of the Dongsan vein group. In Kwangcheon vein group, homo genization temperatures of inclusions range from $240^{\circ}C$ to higher than $360^{\circ}C$ in quartz and from $240^{\circ}$ to $328^{\circ}C$ in early fluorite. As a whole, in Dongsan and Kwangcheon vein groups it seems that there are no distinct differences in mineralogy, salinities and homogenization temperatures. No distinct variations in homogenization temperatures are revealed through about 300 m vertically in both district. The faint trend of increase in salinities in the lower level can be detected. The salinity, $CO_2$ content and the temperature of ore fluid were much higher in the early vein stage and then dropped off in the late stage of mineralization as represented by the quartz and fluorite inclusion data.

도시녹지 평가를 위한 경관지수의 스케일 민감성 분석

이인성,윤은주,Lee, In-Sung,Yoon, Eun-Joo 한국조경학회 2008 韓國造景學會誌 Vol.36 No.2

경관지수는 면적 및 밀도, 모양, 중심지, 고립 및 접근, 접촉 및 산포, 연결성 등 경관생태의 공간적 구조와 패턴에 관한 다양한 정보를 제공해 준다. 현재 100개 이상의 경관지수가 개발되어 많은 연구들에 이들이 사용되고 있다. 그러나 경관지수는 공간해상도 및 분석범위 등 분석 스케일에 따라 다른 결과를 도출할 수 있어서 오류의 가능성을 가지고 있다. 이 연구는 경관지수의 스케일 민감성을 검토하여 우리나라의 복잡한 경관생태에서 비교적 안정적 결과를 도출하는 지수들을 선별하였다. 이를 위해 서울의 5개 연도 - 1985, 1991, 1996, 2000 및 2003년 - Landsat TM/ETM+ 영상을 이용하여 20 범주의 셀 크기와 41 범주의 분석범위에 대해 FRAGSTATS에 탑재된 54개 클래스 수준 지수의 민감성을 검토하였다. 연구결과는 다음과 같다. 첫째, 54개 클래스 수준 지수 중 19개 지수가 스케일 변화에 안정적인 것으로 나타났다. 둘째, 단편화 정도가 지수의 민감성에 영향을 미치며, 녹지비율 $40{\sim}50%$를 기준으로 지수반응 패턴이 변하는 현상이 발견되었다. 셋째, 국내 관련연구에서 빈번히 이용된 16개 지수 중 6개만이 우리나라의 복잡한 경관생태에서 안정적인 결과를 도출하였는데, 이는 단편화 정도 및 녹지비율에 따라 세심한 지수 선정이 필요함을 보여주고 있다. Landscape indices are effective tools to explain the spatial structure and patterns of ecological landscape including area/density, shape, core area, isolation/proximity, contagion/interspersion, and connectivity. More than 100 indices have been developed and an increasing amount of research explains changes in urban spaces using the indices. However, landscape indices have a high level of sensitivity to the scale of analysis - grain size and extent. If the scale sensitivity of indices is not considered, the research may produce inaccurate results. This study examines the scale sensitivity of landscape indices to find relatively stable indices in the complex geographical features of Korea. The scale sensitivity was analyzed using 20 categories of grain size and 41 categories of extent change. Landsat TM and ETM+ images of five years - 1985, 1991, 1996, 2000 and 2003 - were used, and 54 class level indices mounted on the FRAGSTATS program were examined. The results are as follows: First, according to the analysis of the scale sensitivity, 19 out of 54 class level indices were found to be stable to scale change. Second, the scale sensitivity was closely related to the green area ratio, and the typical threshold of change was $40{\sim}50%$. Third, among the 16 indices which were frequently used in the research in Korea, only 6 indices were relatively stable to the scale change. These results can be an effective basis for the selection of indices in the landscape ecology research in Korea.
