We have used Visual Image Tracing(VIT) strain measurement system coupled with a micro tensile testing unit to test thickness and microstructure dependent mechanical behavior of Au film. The advantage using this method is to monitor the real time images of specimen during the test in order to determine its Young’s modulus, yield strength and tensile strength. 0.5, 1 and 2 ㎛ thick films were deposited by sputtering system. Free standing films were prepared through lithography and etching processes. Au films were annealed at 300℃ and 350℃ to achieve microstructure evolution and Focus ion beam (FIB SEM) and transmission electron microscopy (TEM) were employed to characterize grain sizes of films. Thickness and grain sizes dependent mechanical behavior such as stress-strain curve, Young’s modulus and yield strength of Au thin film will be presented.

Jo Myung-am"s or, Jo Young-chool wrote the poem and popular-song poem in 1930s and 40s as Japanese colonial era at the same time and defected to North Korea in 1948 at the age of 35. He was a presentative lyricist of Korean popular song changing over from Korean popular song faltered by Japanese popular songs to the fresh lyrics matching Korean sentiment. However, Jo Myung-am has published very meaningful poems in not only poem but song poem. The result of the study was insignificant so it was judged that the poetic value and meaning weren"t properly proved. "NamSaDang" is a presentative poetry. "Namsadangpae poetry" includes 6 kinds such as ⓛNamsadang, ②Sogo chum(tabor dance), ③Sangmu chum, ④Mudeung chum ⑤Boy ⑥Custom etc. Because the poems of Namsadang is one of poems continuing the tradition of few custom poem in Korean poem history, it is considered as a valuable literary property itself. However, these poems were from an unknown source so it has been studied being left out all the while. Therefore, this article was intended to search the literary significance and to reconstitute the poetry of Jo Myung-am omitted analyzing 6 poems as "Namsadangpae" poem written by Jo Myung-am. Based on this study, it was an opportunity to be investigated refreshingly the relationship between custom and modern poem discussed fragmentarily.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

This study is to choose the most proper model for AGV Throughout simulation of behavior of suspension to reduce trial and error because there is no AGV treating heavy weight at harbor loading and unloading at home. Therefore, we estimate the vibration modes of the various suspensions applied to AGV, which is over 75 ton included the weight of two containers using the Matlab in the case of G and 5G, one of the simulation programs.

CIE1931 색도좌표 상에서 가중치를 적응적인 변환 선에 적용하여 화질개선을 하기 위한 색 변환 알고리즘

전봉기,하주영,강봉순 東亞大學校附設情報技術硏究所 2005 情報技術硏究所論文誌 Vol.12 No.2

본 논문에서는 CIE1931 색도 좌표 상에서 가중치를 적용한 적응적인 변환 선을 따라 색상의 질을 향상시키기 위한 색 변환 알고리즘을 제안 하였다. 제안된 색 좌표이동에 의한 강조 방법은 기존의 색 온도를 이용하는 방법, 색차신호를 이용하는 방법보다 간단한 구조를 가지지만 얻게 되는 결과는 동일하다. 제안된 알고리즘은 사람의 피부색과 같은 사용자가 민감하게 반응하는 색상이 변형되는 것을 막아주며, 이를 위해서 색상좌표를 변환 영역과 비 변환 영역으로 나눈다. 변환영역의 색상은 색상의 좌표와 원점과의 기리의 비에 따라 비선형적으로 가중치를 부여하여 RGB gamut의 외각 선으로 이동하게 된다. 비선형적인 가중치를 변환 곡선에 적용함으로서 색상좌표가 RGB gamut을 벗어나는 현상과 색상이 왜곡되는 현상을 막아준다. 결과적으로, 제안된 색상변환 알고리즘은 색상의 왜곡 없이 원래의 색상의 질을 향상 시킬 수 있다. 본 알고리즘은 Matlab을 이용하여 검증하였다.

본 연구에서는 人蔘 Saonin 이 不水溶性 Vitamin인 Vitamin A와 Vitamin E의 吸收에 미치는 영향을 쥐(albino rat, 100~120g ♂)를 使用하여 觀察하고 다음과 같은 結果를 얻었다. 1) Vit. A 를 人蔘 Saponin 과 함께 Stomach tubing法으로 投與한후 쥐의 血淸을 조사한 結果 試驗群의 Vit.A의 含量은 對照群보다 2倍나 된다. 그러나 3時間後부터는 過量의 Vitamin含量이 減少되기 시작하였다. 試驗群의 肝의 Vitamin A含量도 對照群의 1.5倍였으며 3時間後에는 正常 Vitamin量으로 回復되었다. 2) Vit.E의 경우도 Vitamin E를 投與하고 40分後에 血淸과 肝에서의 Vit. E含量을 調査한 結果 試驗群이 對照群에 比하여 1.4~1.5倍였다. 3) 위와같은 實驗結果는 人蔘 Saponin이 Vit. A와 Vit. E의 吸收를 促進한다는 것을 意味하는 것이다. 4) 한편 試驗群의 腎藏에서의 Vitamin含量이 對照群에 比하여 훨씬 높은 것은 人蔘 Saponin이 不水溶性 Vitamin의 吸收뿐 아니라, 移動 및 排泄에도 크게 영향을 미칠것으로 예상된다. It was attempted in this experiment to observe the effect of ginseng saponin on the absorption of water insoluble Vitamins such as Vitamin A and Vitamin E using albino rat (150-200g,♂) and the following result were obtained. 1) When the Vitamin A and ginseng saponin were fed by stomach tubing, Vit. A concentration of blood serum of test group was found as much as twice that of control, but the Vitamin A content started to decrease 3 hours after. The Vitamin A content of the liver of test animal was also found about 1.5 times that of control and its value returned to normal value three hours later. 2) The Vitamin E contents of the blood and lover of test animals were found as much as 1.4-1.5 times that of control 40 minutes after feeding. 3)The above results suggested tha saponin stimulated the absortion of water insolubl Vitamin A and E 4) On the other hand, the contents of the above Vitamins in the kidney of test animals were significantly higher suggesting that the ginseng saponin also affects the transport of the above water insoluble Vitamins.

자궁내막에 발생한 점막 연관 림프조직 (MALT) 림프종 1예

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.

The purpose of this study is to offer proper physical programs to the middle school EMR boys and to improve their cardiorespiratory function through measuring cardiorespiratory function when they are rest situation, all out situation ten EMR boys, divided into two groups as five exercise boys and five non- exercise ones, played soccer game more than one hour a week for 10 weeks. The results of the measurement by treadmill were as fallows 1. In analyzing the two group t-test score it was found that HR and RQ of both group didn't show statistically significant difference of all(p<0.05). 2. VE, VO₂, Vt, O₂,pluse, CO₂,were revealed the significant difference of rest situation with the exception of all-out situation and recovery(p<0.05) 3. VE, VE/VO₂, O₂/ml/kg. O₂/kg/HR, were revealed the significant difference of all-rest situation with the exception of rest situation and recovery(p<0.05) 4. VO₂, Vt, O₂pluse were revealed the significant difference of recovery situation with the exception of all-out situation and rest(p<0.05) 5. The non-exercise group higher figure in HR, Vt, O₂/ml/kg than exercise group except in VE in the rate of recovery situation in 3 minute
