  • 시스템 엔지니어링은 현대사회에서 성공적인 프로젝트의 실현을 가능케 하는 하나의 개발 방법론으로 선진국에서는 정부, 공공기관, 방위산업체, 민수산업체 등에서 도입하여 시스템 개발 프로젝트를 전수명주기에 걸쳐 효율적이고 체계적으로 관리하고 있다. 시스템 검증 및 확인 프로세스는 시스템 엔지니어링의 핵심 요소 중의 하나로서 고객이 요구하는 시스템 요구사항들이 프로젝트 전수명주기에 걸쳐 올바르게 충족이 되었는가를 입증하고 확인하는 일련의 활동으로 구성된다. 본 논문에서는 국외의 연구 사례들을 조사하여 이러한 검증 및 확인 활동의 독립성이 시스템 개발 사업에 어떠한 긍정적인 효과를 발생시키는지를 분석하였다.

  • Ultrastructural characteristics of hemocytic differentiation pathway in Sericinus montetla Grey were observed with transmission electron microscope. Hemocytic differentiation took place in loose islets of hemopoietic organs as indicated by the presence of differentiating hemocytes; prohemocytes, plasmatocytes, granular cells and spherule cells. They are differentiatied from the stem cells through individual cell lineages. However, differentiating aspects of the oenocytoids were not observed. According to Brehelin and Zachary (1986), the premature hemocytes around the hemopoietic organs were classified into five types; prohemocytes, plasmatocytes, granular cells, spherule cells and oenocytoids.

  • This preliminary study examines historical background of construction, establishment process, and destroy process for the Goryeo-sa-haeng-guan in Myeong-Ju during the Song Dynasty. The research was conducted based on local journals at that time. The Myeong-Ju is one of the famous port cities for marine trade. The Myeong-Ju had a good relationship with the Goryeo. Especially, the Song Dynasty built the Goryo-sa-haeng-guan for Goryeo envoys and traders to maintained a good partnership with Goryeo. A comprehensive review on records and historical issues of the Goryeo-sa-haeng-guan helps us to understand foreign policy and inter-relationship between Korean and China.
