In a software product line approach, developers first develop common software architecture and components by analyzing the characteristics of software members, and then produce each application by integrating components. The approach is considered very effective means for developing and maintaining in parallel a software product family. In this paper, we present an effective specification method in developing software product family. While developing initial members, designers recognize any possible variations during the requirements analysis, analyze the alternatives for each specification item, and record the analysis result in the variations specification as well as the traditional requirements specification document. Both documents will be used later in developing other members of the family.

본 연구에서는 학교 밖 탐구활동의 실태 분석 결과와 수공적 기능이 강조된 HASA 교육과정 기준안에 근거하여 체험 중심 과학캠프 프로그램의 개발 내용과 과정을 분석하였다. 과학캠프 프로그램을 개발하고 적용하는 과정에 대해서는 개발자들과 운영자들이 기획한 자료와 면담 내용을 바탕으로 개발과정에서의 문제점과 개선방안을 분석하였다. 분석한 캠프 프로그램은 개발진이 설정한 개발 방향과 수업 모형을 토대로 과학 강연, 과학 체험학습, 과학 경연, 탐구주제 토론으로 구성되었다. 이 프로그램들은 HASA 교육과정에서 강조하는 수공적 기능, 탐구, 지식, 태도를 모두 포함하였다. 프로그램의 개발 과정에 대한 분석한 결과, 개발 기관의 인적 물적 인프라는 부족함이 없었으나, 프로그램 개발자 중 과학교육학 전공자가 부족하다는 점과 참가 대상 및 비용 측면에서 문제점이 지적되었다. In this study, practice-centered science camp programs developed based on the HASA science curriculum standard and its developmental processes were analyzed. For this purpose, materials related with development of programs and interview protocols were overviewed, and the shortcomings and revision points of the science camp were introduced. The camp programs included science lecture, science experiment, science contest, and inquiry topic discussion. These were based on manipulative skill, inquiry, knowledge, and attitude which were emphasized in HASA curriculum. As a results of analysis, we found that the institutions had enough infrastructures. However, there was no expert in science education, and had some problems in participant's school grade level and participation fee.

After the introduction and development of rigid fixation concept on the traumatized, osteomatized facial bone, miniplates have used for last decade. Therfore, commercial miniplates have been made with many shapes and materials. At present, generally using miniplates are stainless steel and titanium miniplate. These materials must have biocompatibility and less cytotoxicity. In this study, to compare to cytotoxicity of these materials, three kinds of titanium miniplates and two kinds of stainless steel miniplates were inserted to he culture media with fibroblast extracted from I.C.R. mouse and were incubated for 2, 4, 7 days. The cytotoxicity was measured by the viable fibroblast cell numbers in the vicinity of the inserted miniplate surface. The results were as follows: 1. Titanium miniplates that consist of high purity of titanium show weak cyctotoxicity. 2. Titanium miniplates that consist of high purity of titanium show weak cytotoxicity. 3. Stainless steel miniplates present relatively weak cytotoxicity.
