Papillary eccrine adenoma is a rare benign sweat gland neoplasm. It occurs most often as a solitary nodule in women and is located predominantly on the distal portion of the extremities. This tumor is similar to tubular apocrine adenoma in histological and clinical aspects, so distinction of these tumors is still controversial. We report a case of two papillary eccrine adenomas developed on the left popliteal and calf area of a 58-year-old-man, this is the first report of the multiple papillary eccrine adenomas in Korea.

The effect of annealing temperature and holding time on the mechanical properties of pure titanium castings was investigated by means of microhardness test, compression test, microscopic observation, and EDS. Casting process was carried out under argon gas and the heat treatment was carried out under air. The results were as follows : 1. The mechanical properties of the specimens heat-treated at 500, 750℃ were slightly increased, but those of specimen heat-treated at 1,000℃ were remarkably increased by prolonged holding time. 2. The microstructures of specimens heat-treated at 500, 750℃ were bluntly serrated α structure, but that of specimen heat-treated at 1000℃ showed the mixture of acicular α and platelike α structures with a great number of fine precipitates. 4. The surface reaction layer was gradually thinned away by prolonged holding time at 1,000℃, Al and Si elements of the surface reaction layer were homogeneously diffused to the inside of the specimen.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the third year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows : - analyzing and differentiating of epidemic febrile disease - analyzing and differentiating in accordance with the Sasang constitution medicine based on four-type recognition - differentiation of disease according to pathological changes of Chong and Ren channels - standards for diagnosis of women's disease - standards for diagnosis of children's disease - standards for diagnosis of motor and sensor disturbance (-muscle. born, joint, etc.) - standards for diagnosis of neuropsychiatric disease - standards for diagnosis of five sense organ disease - standards for diagnosis of external disease The indivisual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name, notion of diagnosis pattern, index of differentiation of symptoms and signs, the main point of diagnosis, analysis of diagnosis pattern, discrimination of diagnosis pattern, prognosis, a way of curing a disease, prescription, herbs in common use, disease appearing the diagnosis pattern, documents. The standards for diagnosis of each disease was arranged by the diagnostic requirements in the following order : another name, notion of disease, the main point of diagnosis, analyzing and differentiating of disease, analysis of disease, discrimination of disease, prognosis, a way of curing and prescription of disease, disease in western medicine appearing the disease in oriental medicine, documents.

OCL을 사용한 데이터베이스 제약사항 일관성 검증 프로세스

데이터베이스를 활용하는 웹 응용 시스템을 객체지향 기반으로 개발할 경우 클래스 다이어그램, 개체관계 다이어그램 등 다양한 설계 모델의 작성이 필요하다. 이러한 설계 모델들 사이에서 데이터베이스 제약사항의 일관성을 유지하고 확인할 수 있어야 하며, 이를 위해서 정형 언어를 적용하여 제약사항을 명세하는 것은 좋은 해결방법이 될 수 있다. 본 논문에서는 UML의 OCL을 활용하여 데이터베이스 제약사항을 명세하고 이를 검증하는 프로세스를 제안한다. 제안하는 프로세스에 사용하기 위해 데이터베이스 제약사항 중 핵심이 되는 제약사항들을 키 제약사항, 참조 제약사항, 그리고 속성 제약사항으로 분류하였으며, 이에 대한 OCL 명세 방법을 제시하였다. 제안한 방법의 명세 효과를 확인하기 위해 기존의 데이터베이스 모델링에 사용하는 ODL과 E-R 다이어그램과의 명세 정도를 비교하였다. It is essential to develope class diagrams, E-R diagrams, and other various diagrams in case of constructing web application systems with the database applying object-oriented methods. These models have to maintain consistency about constraints of the database and to be checked about consistency. Formal languages are a good solution to specify the constraints. This paper proposes a process that specifies and verifies the constraints of the database with OCL. The constraints of the database can be categorized with three types : Key constraints, Referential constraints, and Attribute Constraints. We shows the specifying method about three types. To validate the effectiveness of the proposed method, we compare the method to ODL and E-R diagram which are used to model the database.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

Basal cell carcinoma is the most common malignant skin cancer in Korea. The lesions are most frequently found in the head and neck region. But penile basal cell carcinoma is very rare and there are only 29 other reported cases. We report a rare case of basal cell carcinoma of the penis in a 76-year-old man. He had a well circumscribed 1.3㎝×1.3㎝ thick scaly plaque with central ulcer in right penile root area for 4 years. The lesion was completely excised and no recurrence for four months.

정밀토양도를 이용한 유효강우량 산정에 관한 연구

김경탁,최윤석 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.2

유역의 유출량을 계산하는 유출모의를 위해서는 직접유출에 기여하는 강우량인 유효강우량을 산정해야한다. 본 연구에서는 SCS CN방법을 이용하여 유효강우량을 산정하기 위해 필요한 유역의 지형자료와 토지피복도 및 토양도 중 정밀토양도의 이용에 관한 내용을 기술하고 있다. 우리나라의 정밀토양도를 SCS CN방법에 적용하기 위해서는 SCS 수문학적 토양군으로의 재분류가 필요하다. 본 연구에서는 정밀토양도를 SCS의 수문학적 토양군으로 분류할 때 허기술과 정정화(1987)의 분류기준과 정정화 등(1995)의 분류기준을 적용하여 유출모의를 수행하여 그 결과를 비교 검토하였다. 대상유역은 IHP 시범유역인 위천 유역과 평창강 유역을 선정하였다. 유출모의는 HEC-1을 이용하였으며 지형인자의 계산은 WMS v6.1을 사용하였다. 대상유역에 대하여 유출모의를 수행한결과 정밀토양도의 분류방법에 따론 유출모의 결과의 차이는 유역에 따라서 달리 나타날 수 있으나, 정정화 등(1995)이 제시한 기준에 의해서 분류된 정밀토양도를 이용할 경우 대상유역으로 선정한 두 지역에서 모두 실측치에 좀더 근접한 결과를 도출할 수 있는 것으로 나타났다. For the simulation of flow phenomenon that calculate basin outflow, it is required to estimate effective precipitation which contributes to direct runoff. This paper is focused on using detailed soil map which is one of the data required to estimate effective precipitation by SCS CN method. Korean detailed soil map must be reclassified as SCS hydrologic soil group when it is applied to SCS CN method. In this study, Korean detailed soil maps which are reclassified as SCS hydrologic soil group by the methods of Her and Jung (1987) and lung et al. (1995) are applied to flow simulation and the results are analyzed. The study sites are Wichon watershed and Pyungchang river basin which are studied by International Hydrological Program (IHP) . HEC-1 and WMS v6. 1 are used to simulate flow phenomenon and calculate geographic parameters. The difference of flow analysis results from each soil reclassification method is different from each sites. But the results of flow analysis approximate observed data by using Jung et al. (1995) method more than Her and Jung (1987) method.
