Benign or malignant tumors that arise in a benign cystic teratoma are rare. Malignant transformation in mature cystic teratoma of ovary is reported to occur in 1~3%. Several types of malignancy can occur from any of three germ-cell layers, but the most common malignancy is a squamous cell carcinoma derived from ectoderm. We experienced a papillary carcinoma arising in a struma ovarii of the complex teratoma. 74-year-old female presented with an abdominal discomfort. A pelvic ultrasonograph and computed tomography detected a 7×6 cm-sized and well-circumscribed cystic mass at the anterior to the uterus. The inner part of the mass was filled with cystic fluid showing low-density, however, solid portion including fat and soft tissue accompanied by calcification was identified in more than half of the entire tumor volume. The patient underwent a bilateral salpingo-oophorectomy. On histopathologic examination, the lesion was consistent with papillary carcinoma with squamoid features arising in a struma ovarii of the mature cystic teratoma. We herein report a case of the very rare papillary carcinoma arising in a struma ovarii of the complex teratoma and review the available literature.

소프트웨어 아키텍처는 소프트웨어 시스템의 중요한 요소를 정의하고 이들 요소 간의 상호관계를 나타낸 전체 시스템의 기본 구조이다. 시스템의 변경과 확장에 용이하고 시스템의 상호 연동성을 확보하는데 있어 아키텍처기반의 기술 접근은 필수적인 요소이다. 이러한 소프트웨어 아키텍처를 분석하기 위한 다양한 방법들이 제시되고 있으며, 이 방법들은 비즈니스요구를 반영하고 품질속성에 따른 시나리오를 만들어 그것을 기반으로 소프트웨어아키텍처를 갖추게 된다. 이에 본 논문에서는 시나리오 기반 소프트웨어 아키텍처 분석방법에 대한 비교 연구를 통하여 향후 소프트웨어 아키텍처 분석을 위한 효과적인 방향을 제시해 보고자 한다.

The purpose of this study was to identify the influence of the Project Approach Teaching to make use of toy on young children's creative thinking; Toy in young children is the best friend and it is always with them. Therefore, I expected that it would be a good subject matter for the development of young children's creative thinking. The study seek to answer to the following questions : Firstly, Is there any significant difference in children's creative thinking between the group of project approach teaching to make use of toy and comparative group? Secondly, Is there any significant difference in the sub-factors of creative thinking in young children between the group of project approach teaching to make use of toy and comparative group? The sub-factors of creative thinking was composed fluency, originality, openness, and sensitivity. The subjects of th study were 56 children of age 5 who were attending at D preschool in Busan city. They were classified into two groups, experimental and comparative group. The children's creative thinking was measured by K-FCTYC(korean Figural Creative Test for Young Children) and pre/post test came into effect. The collected data were analyzed by means of electronic data processing program SPSS/PC WIN 10.0. The method of analysis in the study were t-test and ANOVA for the measure of the difference of children's creative thinking between the experimental and comparative group. The findings of the study are as follows : Firstly, the project approach teaching to make use toy was effective in improving the level of children's creative thinking. there was some significant difference in children's creative thinking between the experimental and comparative group, and the score of experimental group was more height than that of the comparative group. Secondly, the project approach teaching to make use toy significantly influenced the sub-factors of creative thinking. it was effective for the development of fluency, originality, and sensitivity. In conclusion, the project approach to make use toy may be effective to increase creativity thinking and their sub-factors in young children. Therefore, education using toy project approach will service to solve problems in an innovative way and discover new things for themselves.

현재 우리군은 900여개의 크고 작은 정보체계가 각기 독립적(stand-alone)으로 운영되는 연통형정보체계로, 단위 정보체계 각각은 효과적으로 운영되지만 정보체계 간 상호연계에 많은 어려움을 겪고 있다. 이러한 상호연동문제 해결방안 중 하나로 이기종 시스템 간 상호운영 표준기술로 웹서비스의 도입방안을 연구하였다. 민간분야의 웹서비스 추진전략은 국방도메인이 요구하는 웹서비스 추진전략과는 서로 상충되는 면이 존재한다. 이에 국방분야의 특수성을 고려한 웹서비스 신기술을 도입 시, 표준화되고 빠르고 안정적인 국방 웹서비스 프로젝트진행을 위한 기반환경구축을 목표로 국방 웹서비스 프레임워크 모델개발을 추진중에 있다.
