Gastric small cell carcinoma(SCC) is defined as poorly-differentiated neuroendocrine tumor of the stomach, and their morphologic and biologic features arc similar to those of the lung. It is known that this tumor has poor prognosis even in early pathologic stage, It acounts for only 3% of all gastrointestinal SCC. that has been reported only 33 cases outside and 6 cases inside of the comitiy. Most of these reports are related to advanced gastric SCC. as pathologic stage IIIb or IV. This report describes a case of early gastric SCC. pathologic stage Ib.

음성군의 금봉광산에서 시추한 화강암의 코아시료를 대상으로 기본물성과 P파, S파 속도를 측정하고 그들 상호간의 관계를 탐구하였다. 밀도는 2.63∼2.72g/㎤, 공극률은 0.29∼1.84%, 함수율은 0.09∼0.41%의 범위에서 변한다. P파 속도와 S파 속도는 밀도에 대하여 각각 0.8 및 0.7의 상관도를 갖고 비레한다. 반면 공극률에 대하여는 Vp와 Vs가 각각 0.6 및 0.52의 상관도를 갖고 반비례하는 경향을 보인다. 한편 Vp와 Vs는 높은 상관도(0.8)를 갖고 비례관계를 유지한다. On the granitic core samples of Kumbong Mine in Umsong-Kun, the basic physical properties and the velocities of P and S wave are measured, and their inter-relationship was investigated. The physical properties vary in the of 2.63∼2.72g/㎤ for density, 0.29∼1.84% for porosity, and 0.09∼0.41% for moisture content ratio. P wave and S wave velocities show the proportional tendency with the density within the correlation coefficient 0.8 and 0.7, respectively. On the other hand, about the porosity, Vp and Vs show the inverse proportional tendency within the correlation coefficient 0.6 and 0.52, respectively. Vp and Vs are each other in the proportionate relation within 0.8 of correlation coefficient.

CAD를 활용한 자카드 텍스타일 디자인 개발 프로세싱 연구 : 넥타이 디자인을 중심으로 On Based Nec-tie Design

송경자,진영길 한국의류산업학회 2005 한국의류산업학회지 Vol.7 No.1

This study attempts to address the development processing of yarn-dyeing jacquard design by using jacquard textile design professional CAD system to create high valued worth products. To carry out this purpose, two kinds of necktie samples were designed and each of them was different in three types of weaving method. The results arc as follows; All over typo is appropriate when the motive's size is small. And the work can be finished within short time and design can he illustrated by basic jacquard system. However, one point type can represent rather big and audacious motive but it needs lots of working hours and jacquard system. Though the motives are identical, showed many changes in cubicle representation according to weaving methods and the structure. To express simple and modest design, single fabric woven is suitable and in the need of colorful and technical design, expressing by double weft cloths and triple weft cloths rather than single firbric woven are better to give creativity and colorfulness. For the production of jacquard design, cad system using ability is important but the understanding and study of the whole process of weaving development should he made.

A study was conducted to design automotive thermal energy storage for reduction in exhaust emission and enhancing the passenger's comfortability. Ba(OH)2 8H2O was chosen, based on its thermodynamic characteristics and a series of test, as a base material for the energy storage system. Sr(OH)2 8H2O and H2O were added to the base material to protect degradation that is appeared during the cycling test of the pure base material. Thermal storage were, then designed to provide 2,000 kJ of energy within a few minutes of engine ignition with the computer simulation results.

Objectives : To clarify the cytotoxic effect of glucose oxidase(GO) and protective effect of gastrodiae Rhizoma (GR) on spinal sensory ganglion(DRG) neurons, neurotoxicity mediated by GO was measured by MTT assay and neurofilament enzymeimmuno assay(EIA). Methods : DRG neurons were cultured in the media containing various concentrations of GO for 3 hours. In addition, neuroprotective effects of GR, on GO-induced neurotoxicity in DRG neurons were examined after DRG neurons were preincubated with various concentrations of GR for 2 hours before 15mU/ml GO for 3 hours. Results : GO decreased remarkably cell viability in dependently in these cultures, and also RG increased cell viability and amount of neurofilament in DRG neurons damaged by GO. Conclusion : It is suggested that GO has toxic effect in cultured mouse DRG neurons, and also RG was effective in the protection of GO-induced neurotoxicity in these cultures.

LCAOMO calculation has been carried out for thirty chemical carcinogens and nine metabolites of them. The LUMO electron density which is a measure of ability electron to be accepted and observed DNA-Modifying activity which is a measure of mutation relationship was considered. It was found that the sum of LUMO electron density of 1, 2, 4-positions of a relevant trans-butadiene type (F??) in the compound was correlative to DNA-Modifying activity. This means that carcinogenesis closely relate to mutagensis, since the LUMO electron density is a measure of carcinogenic activity of carcinogens as shown earlier. It was also found that LUMO electron density of 1, 2, 4-positions in compounds increase with their metabolic activation. This is in agreement with the experimental result that carcinogen is more electrophilic as metabolic activation. In conclusion, it may be possible to give a theoretical interpretation on the mutation of chemical carcinogens and explain theoretically the fact that the compound have a strong elestrophilicity on metabolic activation.

The flora of Tsushima Islands consists of total 250 species. The major natural forests are coastal shrub forest, low-land forests, mountain forests, secondary forests, and planted forests. The vegetation maps of Tsushima Islands are similar to those of Jeju Islands, Ulreung Islands and the South-coastal districts of Korean Peninsula. The fresh water algae of Korea listed total 8 classes, 20 orders, 47 families, 122 genera and 618 kinds (including 459 species, 1 subspecies and 31 kinds). The fauna of fresh water fishes comprises 25 families, 83 genera, and 132 species in South Korea and 9 families, 20 genera and 22 species in Tsushima Islands, respectively. The Late 0ligocene sedimentation recorded in the Taishu Group reveals an unstable shallow marine depositional environment as shown in sole marks and other sedimentary features. Previous studies on directional features of the Taishu Group have shown that the Paleo-Tsushima Strait and the East Sea originated during the Taishu sedimentation. The provenances of the Taishu Group appear to be the Korean Peninsula and the Early Paleogene sedimentary rocks of Yellow Sea floor and the sea floor between Yellow Sea and the Tsushima Island. The Early Miocene uplift and folding of the Taishu Group must have closed the Paleo-Tsushima Strait connecting Korea and the Japanese Islands. According to previous studies, the Korean Peninsula and the Japanese Islands were connected during the end of the Miocene and the Late Pleistocene. The last isolation commenced during the Riss-Wu¨rm Interglacial age.

Neuropeptide Y(NPY) was first isolated from porcine brain. This discovery has lead some workers to study the distribution of this peptide in the central nervous system of various mammals. In this study the distribution pattern of neuropeptide Y-immunoreactive neurons was examined in the hippocampal complex of Striped field mouse in Korea(Apodemus agrarius coreae) Experimental animals were anesthesized with thiopental sodium and perfused with 4% paraformaldehyde through the left ventricle and the ascending aorta. The brains were removed and transferred 10%, 20% and 30% sucrose solution. Sections were cut on a cryostat into 40㎛-thick. The tissue was immunostained with free-floating and avidin-biotm complex(ABC) method. The results obtained in this study were summarized as followings. 1. The most of NPY-IR neurons in hippocampus proper were found in the polymorphic layer and a few was found in the pyramidal layer. 2. The process run vertically in the deep polymorphic layer and run parallel to corpus callosum in superficial polymorphic layer. 3. The shapes of neurons in hippocampus proper were varied of polymorphic, oval or round, and the nerve fibers were found in the molecular laver and the hippocampal fissure. 4. The highest density in number of NPY-IR neurons on dentate gyrus were found in hilar area of dentate gyrus. 5. The most of NPY-IR nerve fibers were found in molecular cell layer.
