We report a case of cutaneous B cell lymphoma in a 68-year-old male who had primarily developed two 2.0 * 2.0 * 0,6cm sized, dome shaped, dark red colored tumors on the medial side of his left thigh about 4 months previously. His general condition was good and laboratory results were within normal limits, except for the enlargement of aortocaval, paraaortic and left inguinal lymph nodes. Histopathological examinations revealed diffuse dense infiltration of large atypical cells with vesicular nuclei and large prominent nucleoli in the entire dermis. They were largely composed of centroblast and immunoblast-like cells and showed positive reactions to the leukocyte common antigen, and L26 and CD22 was related to peripheral B-cell lineage in the immunohistochemical study. The skin lesions improved completely with an m-BACOD regimen. There was no relapse over a 3-year follow-up period. (Kor J Dermatol 1997;35(2): 312-316)

본 연구에서는 최근 재개발되고 있는 정선지역의 철광산에서 현장 초기지압 시험과 수많은 암석 실내시험을 실시하였다. 본 광산의 측압계수는 심도가 깊어질수록 작아지는 경향을 보였으며 평균값은 1.10으로 나타났다. 본 광산에 주로 분포하는 네 가지 암종인 백운암, 규장암, 화강암, 철광석에 대한 실내시험을 통해 암석의 단위중량, 공극률, 흡수율, 탄성파속도, 일축압축강도, 영률, 포와송비, 인장강도, 쇼어경도, 내부마찰각, 점착력 등의 각종 역학적 특성을 조사하였다. 실내시험 결과의 통계분석을 통해 암종별 물성을 비교하였고 물성 상호간의 관련성을 검토하였는데, 철광석보다는 규장암이나 화강암의 강도특성이 더 컸으며 암석 물성 간의 일반적인 상관관계와는 반대되는 현상도 발견되었다. 또한 Mohr-Coulomb 파괴조건과 Hoek-Brown 파괴조건을 적용하여 네 가지 암석의 파괴조건을 해석하였다. In this study, both in-situ stress measurements and a lot of laboratory rock tests were conducted at a metal mine in Jeongseon, Korea. The stress ratio obtained from in-situ stress measurements showed a tendency to decrease according to depth below surface and its average value was 1.10. The mechanical properties such as unit weight, absorption ratio, porosity, elastic wave velocity, uniaxial compressive strength, Young's modulus, Poisson's ratio, tensile strength, shore hardness, friction angle and cohesion were investigated for the four different rocks mainly distributed at a studied mine, which were dolomite, felsite, granite and magnetite. The mechanical properties of the four different rocks were compared by means of statistical analyses, whereupon the felsite and the granite turned out to have more strength characteristics than the magnetite. The correlation of mechanical properties was also investigated, whereupon a few results against the general correlation were found out. The failure criteria of the four different rocks were finally discussed by means of both Mohr-Coulomb criterion and Hoek-Brown criterion.

We have encountered a rare case of erythema nodosum-like leukemia cutis associated with acute myelocytic leukemia(AML) in a 57-year-old male. He was in good health until about 2 weeks prior to admission, when the systemic symptoms of high fever, anorexia, general weakness and malaise, and subcutaneous nodules developed. The nodules were multiple, red and noted bilaterally on the pretibial areas. Histological findings of his skin lesions showed diffuse cellular infiltrates intermingled with leukemic cells predominantly involving the adipose tissues. The cells displayed negative stainirig to antibodies CD3 and CD20, but positive staining to LCA. The diagnosis of AML(M4) was made by blood and bone marrow studies. He had a rapid downhill course and was discharged after 2 weeks of admission, with no anti-cancer chemotherapy. (Kor J Dermatol 1997;35(3): 556 - 560)

목초(牧草)의 하고성(夏枯性) 방제(防除)에 관(關)한 연구(硏究) -초지피복(草地被覆)이 목초(牧草) 생산성(生産性) 및 영양성분(營養成分)에 미치는 영향(影響)-
김종우,Kim, Jong-Woo 충남대학교 농업과학연구소 1976 Korean Journal of Agricultural Science Vol.3 No.2
북방형(北方型) 목초(牧草)의 하고성(夏枯性) 방제(防除)하기 위하여 1976년(年) 7월(月)1일(日)부터 8(월)月14일(日)까지 Orchard grass, Tall fescue, Red clover, Alfalfa, Crabgrass의 5초종(草種)에 보리짚을 $100g/m^2$, $200g/m^2$, $300g/m^2$ 피복(被覆)하고 목초(牧草)의 성장(成長), 수량(收量) 및 영양성분(營養成分)에 미치는 영향(影響)을 검토(檢討)한 결과(結果) 다음과 같은 결론(結論)을 얻었다. 보리짚 피복(被覆)에 의하여 피복구(被覆區) 지온(地溫)은 무처리구(無處理區)에 비(比)하여 $1.0{\sim}3.04^{\circ}C$의 강하현상(降下現象)을 나타내었다. 피복처리구(被覆處理區)는 무처리구(無處理區)에 비(比)하여 6.0~45%의 성장효과(成長效果)를 나타내었다. $100g/m^2$ 피복구(被覆區)는 무처리구(無處理區)에 비하여 32.77%의 증수효과(增收效果)를 나타내었고 $300g/m^2$구(區) 이상은 부식(腐蝕)에 의하여 7.75%의 감수현상(減收現象)을 표현(表現)하였다. 피복처리구(被覆處理區)에서 생산된 목초(牧草)는 무처리구(無處理區)에 비하여 조단백질(粗蛋白質) 및 가용무질소물(可溶無窒素物)의 증가(增加)를 가져왔고 조지방(粗脂肪), 조섬유(粗纖維) 및 조회분(粗灰分)은 감소현상(減少現象)을 나타내었다. This experiment was conducted for the control of summer depression of cool-season pasture plant. Orchard grass, tall fescue, red clover, alfalfa, and crabgrass were mulched by barley straw with depths of $100g/m^2$, $200g/m^2$ and $300g/m^2$ for 45 days -from July 1, to August 14-, and the effects on growth, yield and chemical composition were observed. The results obetain were as follow: Temperature decrease of $1.0{\sim}3.04^{\circ}C$ was followed after barley straw mulching on the grassland as compared with the control. The growth of the grasses after mulching was hastened, i. e. plant height was increasd 6.0~45% as compared with the control. Barley straw mulching with $100g/m^2$ supported the increase in yield of the grasses with an average of 32.77%, however, average yield was decreased by 7.75% with $300g/m^2$ mulching, apparently due to the rottening of grasses. Chemical compositions of mulched grasses were varied; contents of crude protein and nitrogen free extract were higher, but crude fats, fibre, and ashes were lower than those of the control.

부서지기 쉬운 큰 응집입자의 파괴 없이 미립자의 침강거동에 관한 실험을 정지수면 조건하에서 CCD(Charged Coupled Device) 카메라로 실시하였다. CCD 카메라를 통한 실험은 점착성 미립자의 연직분포의 농도와 농도의 연직분포에 대해 물리-화학적 인자(NaCl, 밀도, 온도 및 pH)의 영향을 조사하는 것이다. 부유된 미립자(alumina와 quartz) 농도의 연직분포는 <TEX>$20,000\;mg/{\ell}$</TEX>까지 CCD 카메라로 측정할 수 있었다. 점착성 퇴적물의 농도의 연직분포는 초기농도의 증가, 온도의 증가 및 염분의 증가로 커진다. 그리고 염분의 첨가로 미립자(alumina) 농도의 연직분포가 quartz보다도 더 빠르게 감소한다. 그와 더불어서 PH은 미립자(alumina) 침강거동에 영향을 끼친다. pH 4.2에서 미립자의 침강률은 낮고, pH 8.9에서 입자의 응집현상 때문에 미립자의 침강률은 크다. pH 9부터 침강 평균속도는 감소한다. Experiments on settling behaviour of fine-grained particles without destroying the large fragile aggregates were carried out in still water with a CCD (Charged Coupled Device)-Camera. The experiments dealt with the measuring of the vertical concentration profile of cohesive particles with a CCD-Camera and the physico-chemical influences (NaCl, density, temperature and pH value) on the vertical distribution of the concentration. The vertical concentration profile of fine suspended particles (alumina and quartz) was possible up to <TEX>$20,000\;mg/{\ell}$</TEX> with a CCD-Camera. The vertical concentration profile of cohesive sediments was on the decrease because of the increasing initial concentration, temperature and salinity. The vertical concentration profile of alumina was on the decrease quicker than quartz with increasing salinity. Furthermore, the pH value affects the settling behaviour of alumina. At a PH value of 4.2 the settling rate of the particles was very low and on the increase until pH 8.9 because of the aggregation behaviour of particles. From the PH value of 9 the average settling velocity was on the decrease.

플록의 입경과 밀도에 따른 부유된 미세 미립자의 침전률 특성에 관한 연구
김종우,Kim. Jong-Woo 한국방재학회 2009 한국방재학회논문집 Vol.9 No.4
본 연구는 점착성 미립자의 침전률에 대한 플록의 영향에 관한 것이다. 연구 진행시 플록 밀도와 입경변화의 영향도 고려하였다. 플록입자의 침전속도는 정지수면에서 측정되었다. 플록 입경과 밀도는 수정된 Stokes방정식에 유체의 밀도, 입자의 밀도, 점성계수 및 측정된 침전속도와 입경과의 관계식으로부터 얻은 플록 차원을 이용하여 분석되었다. 석영과 알루미나의 플록지름은 초기농도가 증가함에 따라 증가되었으며, 염도농도의 증가에 따른 석영의 플록된 입경은 <TEX>$0.8{\sim}10$</TEX> <TEX>${\mu}m$</TEX>이다. 플록밀도는 입경이 증가함에 따라 감소하였다. 플록 침전속도와 입경의 관계는 로그표위에 직선식으로 표현된다. 플록 차원(<TEX>$=n_f$</TEX>)은 초기농도가 증가할 경우 2.65이며, 염도가 증가할 때 2.93이다. 침전속도를 예측하기 위한 비례상수(n)는 제시되었으며, 그 범위는 <TEX>$1{\sim}1.93$</TEX>이다. This paper considers the influence of floc on the sedimentation rate for the cohesive material. The effects of floc density and size changes were also taking into consideration during the experiment. The settling velocity of a discrete floc was measured in a quiescent water column. Floc diameter and density were investigated using a modified Stokes equation with some constants such as water density, viscosity, material density and the floc fractal dimension <TEX>$n_f$</TEX> obtained from the relationship between the floc diameter and the floc settling. The floc diameter of quartz and alumina increased at increasing initial concentrations. The floc size of quartz with increasing NaCl concentration varied between approximately 0.8 um to <TEX>$10{\mu}m$</TEX>. Floc density decreased as floc size increased. The floc settling velocity and the floc diameter have a straight line relationship on a logarithm. The floc fractal dimension nf was 2.65 with increasing of initial concentration and 2.93 with increasing of NaCl. The exponent n to predict the settling velocity was proposed and varied from 1 to 1.93.
