Recently central and local governments developed a huge spatial database and system using full-scale Geographic Information System (GIS). But Inconsistent spatial data through duplicated database management drops off in efficiency and confidence of administration. It is difficult to share data because of their unique system and data type. Under these circumstances Ministry of Construction and Transportation (MOCT) has been carrying out Land Management Information System (LMIS) to computerize land administration and policy affairs and to implement land database such as law, spatial, attribute data. A prerequisite mission of LMIS is to develop open system for solving the problem of duplicated data management and data sharing and for supporting various computer environments such as hardware, software, network etc. The purpose of LMIS is to reuse the existing investment resources and to expand the existing system resources. Therefore the purpose of this study is to investigate a method of LMIS operation under the existing circumstances and expansion of the system in the future. To do this, Supporting various DBMS, GIS server, Distributing Computing Platform(Unix, NT Server) is needed. Especially LMIS need to be developed as open system with interoperability to get independence of application from various GIS servers.

The purpose of this study was to analyze the responses and the behavioral characteristics between mathematically promising students and normal students in solving open-ended problems. For this study, 55 mathematically promising students were selected from the Science Education Institute for the Gifted at Seoul National University of Education as well as 100 normal students from three 6th grade classes of a regular elementary school. The students were given 50 minutes to complete a written test consisting of five open-ended problems. A post-test interview was also conducted and added to the results of the written test. The conclusions of this study were summarized as follows: First, analysis and grouping problems are the most suitable in an open-ended problem study to stimulate the creativity of mathematically promising students. Second, open-ended problems are helpful for mathematically promising students' generative learning. The mathematically promising students had a tendency to find a variety of creative methods when solving open-ended problems. Third, mathematically promising students need to improve their ability to make-up new conditions and change the conditions to solve the problems. Fourth, various topics and subjects can be integrated into the classes for mathematically promising students. Fifth, the quality of students' former education and its effect on their ability to solve open-ended problems must be taken into consideration. Finally, a creative thinking class can be introduce to the general class. A number of normal students had creativity score similar to those of the mathematically promising students, suggesting that the introduction of a more challenging mathematics curriculum similar to that of the mathematically promising students into the general curriculum may be needed and possible.

This study investigates the research trends of SMEs and technological innovations in the last 40 years. Research topics and methodological trends were analyzed for 114 academic papers deals with technology innovation in SMEs. In terms of research subjects, there have been interested in the technology capability and technology accumulation of SMEs in the 1990s, but after the 2000s, research on external open innovation and innovation performance has increased. The empirical analysis studies using primary or secondary data were dominated since the 2000s. We suggest some future research directions, more systematic innovation processes in SMEs, the interactions between technology innovation and external environments, and advanced methodologies on SMEs' technology innovation studies.

Measurement is an imperative content area of early elementary mathematics, but it is reported that students' understanding of units in measurement situations is insufficient despite its importance. Therefore, this study examined lower-grade elementary students' quantitative reasoning of units in length measurement by identifying the levels of reasoning of units. For this purpose, we collected and analyzed the responses of second-grade elementary school students who engaged in a set of length measurement tasks using an open number line in terms of unitizing, iterating, and partitioning. As a result of the study, we categorized students' quantitative reasoning of unit levels into four levels: Iterating unit one, Iterating a given unit, Relating units, and Transforming units. The most prevalent level was Relating units, which is the level of recognizing relationships between units to measure length. Each level was illustrated with distinct features and examples of unit reasoning. Based on the results of this study, a personalized plan to the level of unit reasoning of students is required, and the need for additional guidance or the use of customized interventions for students with incomplete unit reasoning skills is necessary.

유럽연합은 1990년대에 접어들면서 미국과의 경제 격차가 점차 확대되자 미국을 따라잡기 위해 리스본 전략을 채택하였다. 이 전략의 목표는 유럽의 정보화를 통한 성장, 고용, 사회적 참여로 요약할 수 있다. 리스본 전략에서 제시된 정보화 모토는 정책과 연구개발을 2개의 기둥으로 하고, 이 두 영역간의 긴밀한 상호협조를 통해 유럽정보화의 시너지를 창출하자는 것이었다. 정책 부문은 리스본 전략에서 출발하여 신 리스본 전략, i2010 전략으로 발전되어 왔으며, 이에 맞추어 연구개발 부문은 FP5, FP6으로 발전되어 오다가 현재는 FP7이 시행되고 있다. 본 고에서는 FP7의 ICT 연구프로그램에서 제안하는 도전과제와 미래기술전략을 소개하는 한편, 그 정책적 시사점을 도출하였다. FP7 ICT 연구프로그램은 유럽이 차세대 ICT 및 그 사용에 있어서 세계 선도 그룹에 들기 위해 극복해야 할 7가지 도전과제를 제안하고 있다. 이들 도전 과제들은 크게 업계의 기술 목표 및 사회경제적 목표 달성을 위한 과제로 이분할 수 있으며, 향후 10년 간의 목표와 성과물을 제시하고 있다. FP7 ICT 연구프로그램 중 '미래 및 새로 부상하고 있는 기술(FET)' 프로젝트는 예상하지 못했던 아이디어와 발전에 효과적으로 대응하기 위하여 '개방형 FET프로젝트'와 '전 방위적 FET 프로젝트'의 두 가지 상호보완적 플랜을 운영하고 있다. 본 고에서는 이들 프로젝트에 대하여 성과목표, 기대효과, 자금지원 및 예산분배계획을 간략하게 소개하였다. 결론부에서는 앞에서의 논의를 토대로 우리나라의 미래 ICT 기술개발 전략 구상시 참조해야 할 정책적 시사점을 제시하였다.

Up to present science and technology (S&T) policy in Korea has focused on producing academic papers and patents through the increase of investment on research and development (R&D). However, as the role of science and technology on boosting national economy has been emphasized and the current government has established 'creative economy' as a main policy agenda, 'technology commercialization' has been moving onto the center of S&T policy. Technology commercialization policy encourages R&D outcomes of public R&D institutions to be utilized in private firms for their new business development, and this concept is in line with out-bound open innovation, in the sense that it involves the flow of technological knowledge from public R&D institutions to private firms. Based on this understanding, this paper analyses government technology commercialization programs and attempts to suggest policy implications. The results suggest that future technology commercialization policy (1) be specialized in a way of reflecting the characteristics of each government ministry, (2) strongly support technology licensing-out, (3) strengthen the linkage between each programs, and (4) nurture expert groups, such as accelerators who can help and foster technology start-ups.
