유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

This paper presents an object-oriented design for a video conversation system. This paper adapts the traditional client/server architecture and uses JMF for process media transmission. It starts from the analysis of functional/non-functional requirements and it documents the model of the system based on'4+1 View Model.' The manifest in this paper will be used usefully to design a system for cyber university or visual conference based audio/video media transmission.

The purpose of this study is to exhibit fundamental data which can apply to quality and process management of structure concrete using special cement in the construction field investigating strength prediction by maturity method of concrete according to cement types. The activation energy value was derived from the experimental study that experimental factors were selected as W/C ratio of 45%, the kinds of cements of 3 levels of O.P.C, H.B.C, H.S.C and curing temperature of 3 levels of 5℃, 20℃, 35℃. Also, after investigating relationship between compression strength and equivalent ages of concrete according to cement types, the strength prediction was investigated by maturity method. As the above of results, differences between the prediction strength by strength prediction equation and the actual measurement strength were lower, therefore it is considered that the strength prediction by maturity method is possible not only concrete using normal portland cement but also concrete using special cement.

Chronic neutrophilic leukemia is a very rare myeloproliferative disorder which is characterized by severe sustained mature neutrophilic leukocytosis in peripheral blood (PB), hepatosplenomegaly, elevated leukocyte alkaline phosphatase, serum uric acid. serun viatmin B 12 and the bleeding tendency despite normal platelet count and coagulation time, absence of philadelphia chromosome, and the absence of fever or underlying infection or disease sufficient to mimic a leukemoid reaction. We have experienced a 34-years-old male patient with atypical chronic neutrophilic leukemia. On admission, the leukocyte count was 56,860/uL. severe neutrophic leukocytosis with 76% neutrophils and rare immature forms on PB smear. Many neutrophils had toxic granules, and vacuoloes. Leukocyte alkaline phosphatase score was decreased. The cytogenetic study showed Philadelphia chromosome negative with normal karyotype.

The purpose of this study is to investigate and analyze experimentally and positively engineering properties of recycled concrete using high quality recycled fine aggregate according to w/c ratio and unit water contents. And it is intend to present fundamental data for the mix design and the improvement of quality. The results are as follows; According to the increase of W/C ratio, the addition ratio of superplasticizer was reduced, the strength of compressive and tensile showed low and carbonation depth and chloride penetration depth showed high. And according to the increase of unit water contents, the addition ratio of superplasticizer was reduced, the strength of compressive and tensile showed low and carbonation depth and chloride penetration depth showed high.

This research examined closely the influence that sports participation has on lineage-disabled person's society integration, inculcated awareness about obstacle sports to storing in secrecy lovers along with disabled person through this, and wished to grope activation way as integration sports that take part in sports with secrecy lover and present basis data for physical education and welfare policy direction, The statistical information on the subject population for this research is as follows: Research target established lineage person registrated as disabled person by population more than 19 years old that inhabits in Daegu-kwangyokshi until 2.904, To achieve this goal, the study established a hypothetical model based on previous related research, The Systematic Stratified Cluster Random Sampling Method was used in evaluating the sampling data, So, used wave and total 212. copies (92.1%) that distribute questionnaire to 230 people all by validity type. In analyzing the data, the SPSS 11.0 program was used for the t-test, One-way ANOVA and simple regression and the Ducan was used for the posterior test, The statistical significance level was 5%, Following results were obtained through the above research methods and data analyses. The results of the research conducted by using the above-mentioned study methods and data analysis are as follows: First, as the period of participating in sports is longer, the degree of existence, participation consumption and whole society integration is the higher, Second, the higher the frequency to participate sports is, the higher access, participation, whole society integration is, However, in the case of participation participating four times a week shows higher degree of social integration than five times a week, Third, existence degree appears higher when the companion of the participant is a community member, the other disabled, a volunteer worker or the disable himself than when the companion is the family member. Fourth, it appears that the degree of satisfaction from sports activities have an effect on that of consumption. Taking all the results mentioned above into consideration, lineage disabled persons can adapt themselves to society and obtain the society integration by participating in sports activities more frequently and continuously, by finding satisfaction in sports activities, and by taking part in integrated sports activities along with the undisabled, Therefore, systematic devices are necessary that can secure, supplement and foster things such as facilities, programmes, and coaches, which help the lineage-disabled and the undisabled do sports activities together.
