The human body, which is composed of concave and convex curvatures, makes it difficult to transfer into 2D patterns directly from 3D data. In previous studies. Jeong, et al.(2004) suggested the block method was fester and easier when dealing with the triangular patches of male's upper dress form. Although the block method is useful to make a pattern, the information(area, length, etc.) from a 2D pattern would be different depending on the direction of the block method. As a result horizontal and diagonal block methods were suggested as optimal methods for 2D tight-fitting patterns. These block methods were closer to the original area of the 3D scan data than the vertical block method. The total area of the 2D pattern obtained by the horizontal and diagonal block methods showed little differences. In case of the horizontal and diagonal block methods, the total error of the 2D pattern area ranged from $0.01\%\~0.25\%$. In comparing the length of the 2D pattern with that of the 3D scan data, the obtained 2D pattern was $0.1\~0.2cm$ shorter than the 3D scan data, which was within the acceptable range of errors in making clothes. 3D space distribution images between the body surface and the experimental clothing were also measured and $3\%$ enlargement of the original pattern was verified as the adequate adjustment.

Background: This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. Materials and Methods: We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Results: Of the 289 lymph node biopsy specimens received, 154 (53.3%) were from males and 135 (46.7%) from females giving a male: female ratio of 1.14:1. Age of the patients ranged from 2.5 to 96 years with a mean age 33.9 years. The commonest lymph node group affected was the cervical (30.4%) followed by axillary (9.7%) and inguinal (8.7%). Malignant lymphoma [71 Hodgkin's disease (HD), 57 non Hodgkin's lymphoma (NHL)] 128 (44.3%), reactive hyperplasia 68 (23.5%), and tuberculosis 41 (14.2%) were the common causes of lymph node enlargement. While HD, reactive hyperplasia and tuberculosis were commonest in young adult patients (10-29 years old) and rare above the age of 50 years; NHL was the predominant cause of lymph node enlargement above 50 years. Conclusions: Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, lymphomas were the most common (44.3%) followed by non-specific reactive hyperplasia (23.5%) and tuberculous lymphadenitis (14.2%).

The importance of environmental water has been risen in terms of river ecosystem soundness with preventing stream flow depletion in rural area, while enlarging agricultural reservoir project is conducted under the 4 main river restoration project for supplying more water to 4 main rivers. The aim of this study was to estimate the amount of environmental water release and analyze the release pattern during non-irrigation season in enlarged agricultural reservoirs. The 4 reservoirs (Dansan, Samga, Geumbong, Changpyeong) located on the upper region of Nakdong river were simulated applying the operation rule which was determined by release criteria curves. The simulated results indicated that the more environmental water could be released than the spillway release and continuous release was achieved with smaller range of fluctuation. In case of Changpyeong reservoir, average 506.0 thousand $m^3$ environmental water could be released on Feb., and it was about twice as much as the spillway release before the enlargement, and also, the 18 thousand $m^3$/day environmental water could be supplied to a stream consistently after enlargement. From the results, it was expected that the additional environmental water release will improve stream water flow during dry season in terms of quantity and quality of water.

An 11-year-old poodle bitch was presented for investigation of multicentric mammary masses. Abdominal sonography and radiography demonstrated abnormal enlargement of uterus and ovaries. Blood analysis revealed high progesterone concentration. The ovariohysterectomy and mastectomy were performed. Histopathologically, the mammary masses revealed complex carcinoma-tubulopapillary carcinoma with papillary pattern and tubule pattern. In the uterus, cystic endometrial hyperplasia was observed. Scattered inflammatory cells were observed in the endometrial stroma and mucinous material was protruded from endometrial surface. Also, in the ovaries, bilateral ovary granulosa cell tumor was detected. The bitch made a complete recovery following the ovariohysterectomy and mastectomy. This case was a very rare multiple tumor occurrence with bilateral ovary granulosa cell tumor and mammary complex carcinoma. High progesterone concentration was characterized clinically in the bitch.

간경변을 보유한 환자의 복부 CT 영상을 관찰한 결과 비장의 웨이브 패턴(wave pattern)이 정상간을 보유한 사람의 복부 CT 영상과 차이가 있음이 발견되었다. 한편 간경변에 동반된 비장은 일반적으로 비대한 것으로 알려져 있다. 따라서 본 논문에서는 이러한 두가지 원리를 바탕으로, 복부 CT 영상에서 비장의 웨이브 패턴을 이용하여 비장 비대를 효과적으로 진단하는 새로운 방법을 제시한다. 제안된 방법에서는 단순히 비장의 크기만물 이용하지 않고 비장의 형태 변화를 바탕으로 국소적 비장 비대의 자동 판정을 효과적으로 수행할 수 있음을 입증하였다.

With the advent of smart clothing for health care and sports, the sophisticated designs with curved seams are drawing attention. One of the problems in those clothing is to determine the design curves in 2D pattern, such that it corresponds to the lines on the intended 3D body. Moreover, the difficulty increases when the original pattern needs to be changed for various sizes and body types. We compare two methods of pattern enlargement in this paper: one is the offset/projection type, and the other is the split grading type. For the enlarged pattern with offset/projection type, the 3D surface offset was first adopted to transform the standard lower body to the target larger size; next, the design lines were projected to the new 3D surface, following which the 3D pattern was developed from the newly transformed 3D surface. In the second method, the enlarged pant patterns were developed by the split grading method. Here, a 3D pattern was developed from the initial body, and then enlarged to the target size by the conventional split grading method. Two feminine pants patterns were examined by 3D virtual fitting. We observed that the 3D offset/projection pants pattern was well fitted, having an evenly distributed surplus, as compared with the sample developed using the split grading method. The difference between the two patterns were apparent at the location where several curved lines merged.

This study was carrid out to examine a part of the mechanism for the etiology of diabetic complications. Thirty normal and forty streptozotocin(STZ)-induced diabetic rats were used as the animal models. Animals were sacrificed at the time points of 3 days, 1, 2, 4 and 6 weeks after STZ-injection and time course in body weight and organ weight, the levels of blood glucose, plasma lipid patterns, and atherogenic index were measured during 6 weeks. The STZ-diabetic animals showed 63% survival rate and fsting blood glucose levels of the diabetic animals measured in the range of 230-410mg/dL during the experimental period. The body weigh of diabetic animals decreased significantly throughout the experimental period and the relative weights of organs to body weight were significantly higher than the normal control ones. The enlargement of the kidney in the diabetic animals was especially remarkable. Plasma triglyceride concentration in diabetic rats substancially increased from the first week of onset of diabetes mellitus and maintained higher levels than the control ones throughout the whole experimental period. The plasma total cholesterol level and atherogenic index in the diabetic rats were significantly higher than the normal ones from the third day after STZ injection and showed a gradual increase with the duration of the disease. Throughout the experiment, the diabetic rats consistently showed a slightly lower HDL-cholesterol level compared to the normal animals. From the results of this study, it appears that the significant changes in blood lipid pattern in STZ-diabetic animals start from the first week after STZ injection.

선박의 대형화에 따른 풍압면적의 증가 및 갑작스런 돌풍 등 자연환경의 급격한 변화 등으로 묘박 중인 선박이 주묘 되는 현상이 자주 발생되고 있다. 특히, 선박운항자의 관점에서는 풍속 및 파랑 등의 외력 변화에 따른 주묘 발생 시점 및 주묘 형태, 주묘시의 속력과 주변 선박 또는 장애물과의 충돌 가능성 등을 고려한 적절한 대응 방안이 모색되어야 한다. 본 논문은 실습선 한바다호가 단묘박으로 묘박 중 기상이 점점 악화되면서 실제로 주묘가 발생한 현상을 검토한 것으로, 묘박 당시의 풍압력, 유압력, 표류력, 선체운동 그리고 파주력 등을 분석하여 주묘의 발생 가능성 및 한계 외력을 고찰하였다. 또한, 당시의 외력 조건하에서 발생한 주묘패턴을 분석하여 선수방위 변화량, 스윙폭, 주묘 속도 등을 확인하였다.
