In order to cope with the changes in the future battlefield that the 4th industrial revolution technology will bring, the development of an intelligent weapon system that quickly reflects new technologies is urgent. Since the intelligent weapon system refers to the CPS consisting of sub-systems with mobility, the functional safety of CPS must be implemented in advance to prevent and mitigate accidents. A TFFS(Traceability Framework for Functional Safety) that can trace the cause of the accident and the safety analysis of CPS is proposed, and a method that can be used in the SW safety management framework is shown. In addition, the validity of the framework was confirmed by applying TFFS to the unmanned military surface reconnaissance CPS scenarios.

저자들은 만성 설사와 하지 부종을 주소로 내원한 63세 여자 환자에서 류마티스 관절염과 연관되고 대장에 국한된 속발성 유전분증을 진단하였고 환자의 임상경과를 기존의 문헌 고찰과 함께 보고하는 바이다. Suspicion of gastrointestinal amyloidosis in patients without known history of amyloidosis is difficult, but gastrointestinal amyloidosis should be considered in those older than 30year with unexplained diarrhea, weight loss or malabsorption. We experienced a case of an 63-year-old female in patient with rheumatoid arthritis, who have a chronic watery diarrhea caused by colonic amyloidosis. Congo-red stain and immunohistochemical stain for amyloid A protein of colonoscopic pathologic specimen showed positive response. Other organs such as kidney, heart, liver and skin, were not involved by amyloidosis. She was diagnosed to secondary and localized colonic amyloidosis related with rheumatoid arthritis. In spite of anti-rheumatic therapy, our patient did not recover.

CMV 감염은 주로 면역기능이 저하된 환 자에서 흔한 기회감염으로 상부 위장관에서 의 내시경 소견은 경미한 발적에서부터 궤 양까지 다양하다. 저자들은 흑색변을 주소로 내원한 환자에서 내시경적으로는 악성궤양 의 소견을 보였으나 궤양부위 조직검사상 거대세포바이러스 봉입체를 관찰하여 CMV 감염에 의한 궤양으로 진단되었고 면역억제 의 원인을 추적하여 HIV 감염을 확인한 증례가 있어 보고하는 바이다. Cytomegalovirus (CMV) causes a wide spectrum of disorders in immunocompetent and immunocompromised patients, however it is more frequent and raises more clinical concerns in immunocompromised patients due to its severity. Moreover, suspicion or recognition of gastrointestinal CMV infection by routine laboratory tests and endoscopy with biopsy is difficult since blood tests and pathology do not always reveal the clues for immune deficiency such as leukopenia or inclusion bodies-the hallmark of CMV infection and also due to the lack of specific endoscopic findings. We report a case of an HIV infection without leukopenia whose initial presentation was a solitary CMV gastric ulcer, which initially was suspected as an advanced gastric cancer with melena.

Systemic lupus erythematosus is an autoimmune disease characterized by the production of variety of autoantibodies, especially antinuclear antibodies, with a diverse array of multisystem inflammatory destructions. However, the etiology of lupus has remained elusive. The interpretation of heterogeneity of systemic lupus erythematosus has suggested that different genetic and environmental components might play a role in the development of this disease, The recognition that familial lupus and increased concordance rate in monozygotic twins suggest the possible important role of genetic components. In this paper, we describe a familial systemic lupus erythematosus in monozygotic twins and their mother, with literature review for possible genetic factors that involving pathophysiology of systemic lupus erythematosus.
