In an extremely enlarged right heart, the repeated midline sternotomy was considered to involve the risk of massive hemorrhage. A right thoracotomy provides a convenient and safe way to approach the tricuspid valve in patient who have had previous heart surgery through a midline sternotomy.

Intravenous leiomyomatosis is a rare neoplasm characterized by intravenous growth of histologically benign smooth muscle cell tumor. We report a case of intravenous leiomyomatosis with right atrial extension in a 19-year-old we-man. Various surgical techniques and approaches have been previously reported. In this case, the tumor was re-moved with a single-stage approach via laparotomy without cardiopulmorary bypass.

A great variety of models including marine ecology model, water quality model, marine fluid model have been used in the marine research. The results of marine model is presented as a numerical value that is difficult for researcher to understand. In this paper, we developed a method for conversing and presenting results of marine models to visual form to improve the visualization of modelling results that is difficult to analyze and applied the method in actual practice.

A terrestrial LiDAR was used to acquire precise and high-resolution topographical information of Malipo beach, Korea. Terrestrial LiDAR and RTK-DGPS (VRS) were mounted on top of a survey vehicle and used to scan 20 times stop-and-go method with 250 m spacing intervals at ebb tides. In total, 7 measurements were made periodically from 2008 to 2009 and after each beach replenishment event. We carried out GIS-based 3D spatial analysis such as slope and volume calculations in order to assess topographical changes over time. In relation to beach replenishment, comparative analysis of each volume change revealed them to be similar. This result indicates that the terrestrial LiDAR measurements are accurate and can be used to analyze temporal topographical changes. In conclusion, the methodology employed in this study can be used efficiently to exercise coastal management through monitoring and analyzing beach process such as erosion and deposition.

This study examined the motif, weave structure, fabric density, and thread thickness of the patterned silks excavated from the Lady Lee's Tomb to trace the weave composition of the 18th Century in Korea. Different weave compositions were adopted depending on the weave structure. Two weave structures appeared in these patterned silks : simple gauze and satin damask. In the case of simple gauze Jergori, all the components, Gil(bodice), Somae(Sleeve) had similar fabric density and thread thickness. On the other hand, the satin damask Jergoris was composed of the components of different fabric density and thread thickness. According to the fabric density and thread thickness, the motif sharpness of damask Jergori was represented in three different ways : smooth and clear, rough and clear, and rough and vague. This revealed that Lady Lee selected not only pattern but also fabric density and thread thickness in the design of damask Jergori.

은하의 형태학적 진화 양상을 분석하기 위해 허블 울트라 딥 필드 (Hubble Ultra Deep Field; HUDF)에 있는 밝은 은하를 조사하였다. Coe et al. (2006)의 HUDF 카탈로그에 포함된 적색편이, 적경, 적위, 밝기 등급, 픽셀 면적 값을 사용하여 HUDF은하의 B필터 영상에서 밝은 순서로 1000개의 천체를 선택하고 이로부터 939개의 은하의 육안 분류를 수행하였다. Elmegreen et al. (2005)의 분류 방법에 기초하여 타원 은하, 렌즈 은하, 나선 은하, 올챙이 은하(Tadpole), 이중 은하(Double), 사슬 은하(Chain), 덩어리 은하(Clump cluster)와 그 외의 불규칙 은하로 분류하였다. 이렇게 분류된 은하의 분류형과 은하의 적색이동 사이의 관계를 분석하여 HUDF 은하의 적색편이에 따른 형태학적 진화 양상을 찾아낼 수 있었다. 올챙이 은하, 이중 은하, 사슬형 은하, 덩어리 은하 등 병합 단계에 있는 것으로 추정되는 은하들은 적색편이가 작을수록 그 수가 대체로 감소하는 경향을 보이는 반면, 나선은하들은 적색편이가 작을수록 그 수가 증가하는 경향을 보였다. 또한, 적색편이와 은하 크기 사이의 관계를 보았을 때 낮은 적색 편이에서 나타나는 상대적으로 큰 은하들이 대부분 나선 은하였으며 이러한 결과는 은하 생성의 Bottom-Up 가설로 설명이 가능하다. 이와 함께 은하 형태의 정량적 분석을 위해 각 은하의 CAS와 함께 M20, Gini Coefficient(G)를 구하여 이들과 육안 분류와의 관계를 분석하여, CASGM20, 으로부터 은하의 분류 형을 찾는 방법을 모색하였다.

The Purpose of this study was to isolate and identify fungi found in excavated clothes dating on the 16th century. As a result of microscoping with LPCB staining, seven isolated strains were classified-Acremonium strictum, Acremonium kiliense, Fonsecaea sp., Candida sp., Trichoderma sp., Cladosporium spp., Penicillium spp.. In the process of isolation and identification of fungi by the sort of textile, more fungi were found in cotton, cotton batt and silk than in ramie and hemp, suggesting that hemp has antibacterial characteristics due to the presence of lignin. In the Comparison washed samples with unwashed ones, there were more kinds of fungi in washed samples. In the cellulase activity test, Acremonium kiliense had the highest level cellulase activity, suggesting that Acremonium killiense has an important Influence on damage of textiles.

In this study, the effect of sizing on the physical and mechanical characteristics of Hansan ramie was studied. 2 kinds of Hansan ramie were used for this study and one kind of the chinese ramie was also used for comparing with the characteristics of Hansan ramies. The following results were obtained from this experimental study. The wrinkle recovery angle was gradually reduced according to the increasing of the concentration of sizing agent. As the size agent could easily penetrate between the thick yarms, the effect of sizing on the wrinkle recovery angle was evident on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently than the bending properties. The other mechanical properties didn't changed much by sizing. The calculated primary hand value also showed that the ramie became more stiff after sizing.

우리 민족(民族)의 희노애락(喜怒哀樂)과 함께 흘러온 민속주(民俗酒)는 우리의 문화(文化)와 더불어 발전(發展)되어 왔었다. 그러나 일본(日本)의 지배(支配)를 받게된 이후(以後)에는 대부분의 민속주(民俗酒)는 밀주(密酒)로 규정(規定)되어 주조(酒造)가 금지되어 왔으며 해방후(解放後)에도 한국정부(韓國政府)의 양곡정책(糧穀政策)으로 인하여 특히 1961년(年) 이후(以後)에는 쌀을 사용하는 민속주(民俗酒)는 강력(强力)하게 금지(禁止)되었고 민속주(民俗酒)에 관(關)한 문화(文化)는 거의 자취를 감추게 되어 왔었다. 그런데 다행(多幸)히도 1985년(年)에 문공부(文公部)에서 민속주(民俗酒)의 주조(酒造) 기술(技術)을 가진 많은 기능인(機能人)을 문화재보호(文化財保護)의 차원(次元)에서 발굴(發掘)하였고 그 기능(機能)을 보존(保存) 계승(繼承)하도록 노력하였다. 따라서 정부(政府)에서는 1988년(年) 9월(月) 전통(傳統)과 기술(技術)이 인정(認定)되는 24종(種)이 민속주(民俗酒)를 민간인(民間人)에게 주조(酒造)할 수 있도록 예비(豫備) 가능(可能)한 바 있었다. 그 24종(種)의 민속주(民俗酒) 중(中)에서 한산(韓山) 소곡주(素穀酒), 경주(慶州) 법주(法酒), 천(川) 박시주(朴?酒), 안동(安東) 소주(燒酒), 이리 이강주(梨薑酒)에 관(關)하여 그 유래(由來), 특징(特徵), 전승(傳承)의 근원, 제조현황(製造現況) 그리고 전래(傳來)된 일화(逸話) 등을 조사(調査) 수록(收錄)하였다.

Propyl gallate used as an antioxidant was examined for its effects on murine Immune system and metbemoglobin content treated with anillne. As immunotoxicology assay parameters, we adopted circulating leukocytes and immunoorgan weights for pathtoxicology, IgM plaque forming cells and Artbus reaction for humoral immunity. Propyl gallate's effects were observed as follows; 1. Propyl gallate decreased circulating leukocyte counts, dose dependently. 2. Relative immunoorgan weigbts were not affected. 3. Propyl gallate diminisbed IgM PFCs/spleen cell and IgM PFCs/spleen. 4. Propyl gallate decreased Arthus reaction. 5. Propyl gallate did not affect metbemogiobin content treated wltb aniIIne.
