This study is aimed to implement a preferred generalization classes for gifted students. By designing and applying the generalization lesson using GSP, we tried to investigate the characteristics on the class. To do this, we designed a lesson on generalization of Viviani theorem and applied to 13 8th grade students in a math gifted class. As results, we could extract five subjects as followings; mediating the conjecture by GSP and checking the pattern, misunderstanding the confirm by GSP as a proof and its overcoming, digressing from the topic and cognitive gap, completing the proof by incomplete conjecture, gap between the generalization and understanding generality. Based on this subjects, we discussed the educational implications in order to help implement a preferred generalization classes for gifted students.

Inscriptions are integral parts of the current science textbooks, and become medium that makes sense of scientific concepts effectively. This study analyzed the inscriptions from five science textbooks at the secondary level in terms of its type, function, and structures. Analyzing types of inscriptions resulted that the ratio of frequently used photographs and illustrations were much higher than that of graphs and tables used. In case of function analysis, illustrative and complementary functions were dominant in terms of frequency and ratio, whereas explanatory, decorative and inquisitive functions were relatively rare. Inscriptions of single structure was much more than multiple structure. Multiple structure of pair and series were mainly used for representing contrast and sequence, respectively. The proportion of inscriptions in type, function and structure across the textbooks was significantly different. Based on the results, it was suggested that semiotic study about the function and the structure of inscriptions need to be carried out in earth science area to better understand the pedagogical implications of inscriptions in school science.

전염병 정보화사업은 1995년 콜레라의 집단 발병을 계기로 1996년부터 추진되었다. 교통의 발달과 국제교류의 증가는 전염병의 전파와 확산속도가 빨라져 국민건강을 위협하고 있으며 기존의 수작업만으로 정보수집 및 효율적인 전염병관리가 어려워 체계적이고 효율적인 전염병관리를 위하여 국가적 D/B 구축, 전염병관리의 의사결정지원자료 축적의 필요성 제기되었으나 독자적인 망 구축에는 막대한 예산이 들고 망의 운영과 유지관리를 위한 예산과 조직의 한계가 있는 상황에서 콜레라 발생을 계기로 보건복지부 방역과, 국립보건원, 국립서울 검역소, 경기도 6개 보건소 및 경기 및 인천 보건환경연구원을 실험적으로 연계하여 전염병 관리에 필요한 정보의 내용과 흐름, 자료 관리를 위한 기관별, 자치단체별 역할과 기능 등에 관한 개념 정립 둥 전산개발과 함께 제도정비 방안 등이 동시에 수행되었다. 이러한 실험과 연구 결과를 토대로 1998년부터 인터넷을 활용한 전염병의 신고 보고, 전염병관련 자료의 D/B를 통한 전염병의 발생 예측, GIS 등 전염병에 관한 모든 정보를 제공할 수 있는 portal site 구축을 위한 2단계 정보화사업이 정보통신부 지원 하에 시도되었다. 약 2년간의 작업 결과 전염병관리의 전산화 가능성이 확인된 후 전염병예방법을 개정하여 전산 보고의 제도적 틀을 만들고 2000년 8월부터 법정전염병은 전산 보고가 이루어 지고 있다. 일방적이 보고이외 전염병관리의 쌍방화를 위하여 각종 지령/정보의 전파, 각종 통계, 지침, 교육자료, 전염병관련 논문 등을 제공하고 있으며, 상담, 민원접수는 전염병 관련 정보의 전문화와 함께 국민과 호흡할 수 있는 시스템으로 운영될 수 있도록 설계하였다. 그러나 현재 사용하고 있는 WEB EDI가 가진 속도 문제, 응용프로그램의 문제로 신고 보고를 C/S 버전으로 전환하여 사용자의 편리성을 증진하고 있다. 또한 예방접종자료의 전산화를 통한 이상반응 관리, 접종주기 관리, 예방접종으로 관리할 수. 있는 전염병관리(Vaccine preventable disease), 학교에서 발생하는 전염병의 감시 등 전염병 포탈 사이트에 걸맞게 정보 내용을 한층 확대하고 있고 일선의료기관도 활용할 수 있는 시스템으로 발전시키고 있다. 이를 위하여 정보관리과도 신설하였다. 그러나 전염병관리의 전산화는 궁극적으로 전염병 자료의 지역화와 그를 통한 전염병관리의 분권화 및 지방자치화를 이루고자 하는 것이다. 기술적인 측면에서 전산망은 쉽게 만들 수 있으나 전염병관리의 개선과 그 정착은 1-2년간의 전산프로그램개발 작업만으로 달성되기는 어려우며 범국가적인 노력과 더불어 일선보건요원의 교육과 훈련 및 보건소장 등 보건관리자의 전산마인드 개발 등의 작업도 매우 중요할 것으로 사료된다.

In terms of development for CMC computer science curriculum was started from 2006 year, and it was confirmed at 2013 year and adapting through 1 to 8 grade. CMC is focused on the "Develop computer fluency, not just computer literacy", "Develop thinking process skills, not just content mastery", and "Highlight the interconnectedness of knowledge, not just address a topic/subject in isolation" as a base of the curriculum. CMC have selected core factors which are Thinking process skills, Computer literacy integrated with fundamental concepts and thinking skills, Thematic integration, Spiral curriculum, and Scalability. Once CMC have been developed as a common computer curriculum by India government, both of computer training course and textbook development were conducted by government. In addition, they are trying to enforce the computer education. It suggests to Korea some significant points which were the necessity of Computer education as an independent subject and the requirement of Software education and Computational thinking as an educational content.

This paper presents a case history of a geosynthetics-reinforced segmental retaining wall, which collapsed during a severe rainfall immediately after the completion of the wall construction. In an attempt to identify possible causes for the collapse, a comprehensive investigation was carried out including physical and strength tests on the backfill, stability analyses on the as-built design based on the current design approaches, and slope stability analyses with pore pressure consideration. The investigation revealed that the inappropriate as-built design and the bad-quality backfill were mainly responsible for the collapse. This paper describes the site condition including wall design, details of the results of investigation and finally, lessons learned. Practical significance of the findings from this study is also discussed.

The purpose of this study was to explore $6^{th}$ graders learning progression for lunar phase change focusing astronomical systems thinking. By analyzing the results of previous studies, we developed the constructed-response items, set up the hypothetical learning progressions, and developed the item analysis framework based on the hypothetical learning progressions. Before and after the instruction on the lunar phase change, we collected test data using the constructed-response items. The results of the assessment were used to validate the hypothetical learning progression. Through this, we were able to explore the learning progression of the earth-moon system in a bottom-up. As a result of the study, elementary students seemed to have difficulty in the transformation between the earth-based perspective and the space-based perspective. In addition, based on the elementary school students' learning progression on lunar phase change, we concluded that the concept of the lunar phase change was a bit difficult for elementary students to learn in elementary science curriculum.

A methodology for BIM Quality Assurance in the construction industry is becoming increasingly an important issue to determine the reliability of BIM. However, the quality assurance of BIM is currently limited to check 3D models, such as clash detection and space layout while verification methods for disciplinary BIM results from structural engineering, mechanical engineering, and estimation do not exist yet. Particularly, in the BIM-based estimation mathematical equations to take off quantities are not clearly exposed so that the results are not quite accepted at practices. With the concept of reliability engineering defined in the manufacturing industry to improve reliability of outcomes of BIM-based quantity take-off, impacting factors that affect reliability of BIM-based quantity take-off were derived. It was found that the factors also include the modeling method and the features of a BIM tool. Therefore, this research aims to propose modeling and verification methods to improve reliability of BIM-based quantity take-off through the pilot test that was performed with commercial BIM tools and IFC-based BIM data.
