The simultaneous occurrence of primary gastric lymphoma and adenocarcinoma is rarely reported. We here report a case of synchronous double primary tumor of advanced gastric cancer and diffuse large B cell lymphoma. A 65-year-old woman underwent an esophagogastroduodenoscopy for the evaluation of abdominal discomfort of two months` duration. The endoscopic examination showed an ulcerating tumor in the gastric antrum and thickened folds in the fundus and the microscopic examination revealed an adenocarcinoma in the antrum and a diffuse large B-cell lymphoma in the fundus. She has had total gastrectomy and CHOP chemotherapy with rituximab. Since the cases of synchronous double primary gastric tumors have been increased on the recent medical advances, when a gastric tumor is detected for the endoscopic examination, an endoscopist has to make every endeavor not to miss another tumor in the stomach.

This study is about to constructing BOM for managing and integrating information, which is drawing, technical data, attribution, design, ordering, cost, weight, process, service ,etc. based on train"s system, elements, substructure, assembly, components, parts during whole train"s lifetime of the next generation. The BOM is the mostly basic structure information as hierarchical data what are parts consisted specific products. The BOM was utilized as essential elements for collectively managing through informing all of the business activity from ordering to suppling. The BOM in railroad is consist of two parts. One is Engineering BOM for design, the other is Production BOM for production, which are utilized in development calculating the quantity of materials. Also the Maintenance BOM is applied to suppling parts and managing malfunction in railroad corporation like the Seoul Metro. There are many kind of BOMs, because of the special character for each step. Therefore We have need to develop BOM which is able to integrate drawing, technical data for helping good circulation between RAMS applied maintenance using database and helpful know-how for development and production. Also the BOM of the next generation must be consisted regard to whole life-cycle.

N/A Because of the limited validity of serologic tests, there has been interest in alternative ways of assessing prognosis and disease severity in systemic lupus erythematosus(SLE), espec ally in direct histopathologic evaluation of affected tissue. Since the renal disease is still a major cause of morbidity and mortality in SLE and the kidney is the most accessible organ by biopsy, the role of renal biopsy in the management of SLE has been discussed frequently. It is known that despite of the absence of clinical abnormalities of urine, histological examination of renal tissue has been shown variable morphological changes including diffuse proliferative type that has the worst prognosis in lupus nephritis. To investigate the usefullness of renal biopsy and the treatment modalities we performed the analysis of clinical and pathological findings in lupus nephritis without clinical renal involvement. Among the 95 patients of SLE, the number of silent lupus nephritis was 23, who were less hypertensive and clinically more favorable. The decrease of C3 and C4 was more marked in the patients who had the renal symptoms clinically. The severity of extrarenal symptoms was not correlated with whether the patient had the renal symptoms or not. The pathologic classification in silent lupus nephritis was as followings; WHO class IIa;8, IIb;7, class IIl;4, class IV;3, class V;1 respectively. Thus we concluded that the diffuse lupus glomer-ulonephritis could be clinically silent and the type of morphologic lesion in lupus nephritis cannot be deduced from the clinical criteria alone. It may be necessary to perform the biopsy in any SLE patient, regardless of the clinical renal involvement.

이 연구는 NCS 기반 기계 절삭가공분야 실무과목에 대한 교사들의 인식을 분석하여 교육 환경 개선 방향에 대한 기초자료를 제공하는데 그 목적이 있었다. 이 연구의 결론은 다음과 같다. 첫째, NCS 기반의 기계 절삭가공분야 실무과목에 대한 교사의 인식을 분석한 결과, 전반적으로 중요도와 실행도의 분석 결과 전체 중요도 평균(4.17)과 실행도 평균(3.83)에 대한 인식 수준 차이가 발견되었다. 둘째, 개별 실무과목의 IPA에서는 선반가공, 밀링가공, 컴퓨터 활용생산, 측정의 4개 영역 중 밀링가공과 컴퓨터 활용생산의 2개 과목은 현상유지 영역에 해당하였으로 이 영역이 학교 현장에서 적절히 운영되고 있음을 알 수 있었다. 셋째, 개별 실무과목의 능력단위 별 IPA에서 현상유지 영역에 해당하는 능력단위는 14개였으며 이에 해당하지 않는 점진개선 영역(8개), 초과달성 영역(4개), 중점관심 영역(3개)의 능력단위에 대해서는 교육 여건의 검토가 필요하다. 연구의 결론을 바탕으로 다음과 같이 제언한다. 첫째, 절삭가공분야의 실무과목에 대하여 교사가 인식하는 중요도에 비하여 실행도가 전반적으로 낮은 이유를 밝히기 위한 후속 연구가 요구된다. 둘째, 중요도에 대한 인식이나 실행도를 개선하기 위한 구체적인 방안에 대해 심도 있는 연구가 필요하다. The purpose of this study was to analyze teachers perceptions of practical subjects in NCS-based machine cutting process and to provide basic data on how to organize related curriculum and improve educational environment. Based on the findings, the conclusion is as follows.First, as a result of analyzing teacher s perception of NCS-based working subjects in the field of mechanical cutting, overall analysis of importance and performance revealed that there was a difference in recognition level between overall importance average (4.17) and performance average (3.83). It became. Second, in the IPA of each practical subject, the two subjects of milling and computerized production among the four areas of turning, milling, computerized production, and measurement were the status quo, and thus, they were properly operated at the school site. Could know. Third, there were 14 competency units in the IPA by individual competency, which were the status quo for the status quo, and that did not correspond to the gradual improvement area (8), the excess achievement area (4), and the key area of interest (3) The competency unit of the study needs to be reviewed. Based on the conclusions of the study, the following suggestions are made.First, follow-up studies are needed to clarify the reason why overall performance is low compared to the importance perceived by teachers in the field of NCS-based cutting process. Second, in-depth research is needed on the concrete measures to improve the recognition and performance of importance.

The 2-way valve was manually worked for fluid controling. In this case, the problems of pressure control and security of worker was existed. 3-way auto change valve makes the fluid flow to become fine and auto change, work efficiency and quality are increased. The 3-way auto change valve needs air flow analysis for application on industry. In this study, the 3-way auto change valve was analyzed on fluid flow of maximized velocity, minimized velocity, air pressure and air density by changing entrance air velocity. The results was that the maximum velocity lineally increased according to increase entrance velocity and Maximum pressure increased non-lineally.

Porous Al metal was produced by batch type casting process. In this foaming process, the viscosity and surface tension of molten Al as two most important factors have been investigated in the temperature range of 680-95$0^{\circ}C$ by the ring method and rotational method respectively. The experimental results showed that both the surface tension and viscosity of the melt decreased linearly with increasing temperature. Addition of Ca decreased surface tension, but increased viscosity significantly.
