Inquiry has been emphasized in science classrooms, but the problems shown in the inquiry are somewhat different with ones that students usually meet and experience in everyday life. The purpose of this study is to investigate how attitudes toward the task and thinking skills affect students' problem solving process, especially, the way of creating a problem space and elaborating problem solving strategies when they have little schema. The difference in students' problem solving strategies of Lego Robotics class, one of the summer programs for $4^{th}-6^{th}$ grade gifted students, which is new to them, was investigated. The results are as follows: (1) The difference in attitudes toward the task, or selection and identification of the missions, and the perception of operators, affected creating a different problem space. (2) Different level of thinking skills, or analytical and flexible thinking, efficient elaborative skill, and application of schema affected a different level of elaboration of the problem space and resulted in asuccess rate of problem solving. (3) Different initial problem space resulted in different problem solving strategies. But without thinking skills, students could not elaborate problem solving strategies efficiently. Several instructional recommendations to promote scientific inquiry were suggested based on the results.

The purpose of this study is to analyze the teaching and learning strategies included in the inquiry tasks of elementary moral textbooks with multiple intelligences (M.I), and to propose educational information services of teacher librarians. It was found that the tasks were mainly designed by the linguistic intelligence, logical & mathematical intelligence and spatial intelligence. In terms of the information literacy process, linguistic intelligence and spatial intelligence are mainly applied to the analysis-understanding stage. Logical & mathematical intelligence is applied to the stage of comprehensive-application and linguistic intelligence is applied to expression-delivery step. In order to cultivate the insufficient M.I in inquiry activities, teacher librarians should improve room and teaching materials of their school library and provide workbooks using the graphic organizer after analyzing the linkage of the inquiry tasks between the subjects.

온톨로지는 시맨틱 웹의 핵심 기술 요소로서 지식을 개념화하고 명세화해서 의미론적 지식체계를 구축한다. 온톨로지는 개념적 모델링(Conceptual Modeling)을 통해 실제 세계의 지식(Real World Knowledge)을 표현하는 중요한 수단으로 제안되었고, 수많은 정보에 대한 지식관리를 효과적으로 수행할 수 있는 토대를 제공한다. 본 연구에서는 연구과제회의를 대상으로 온톨로지를 설계 및 구축한다. 과제 진행에 수반되는 다양한 회의와 관련자료는 과제의 성공적인 수행을 위해 반드시 관리되어야 한다. 일반적으로 회의에서 참석자들 사이에 정보 공유 및 자료 검색이 어렵고 회의일정 조정이 번거로우며 회의자료 관리가 체계적이지 못하다. 따라서 연구과제 진행과정의 회의와 관련자료들을 분석/분류해서 개념적 모델링을 통해 연구과제회의 온톨로지를 구축하고자 한다. 향후 이를 활용하여 지능형 반응 공간에서 회의 관리 및 서비스 제공을 할 수 있다.

Purpose : This study attempted to investigate the effects of supply of highly concentrated $(30\%)$ oxygen on human ability of visuospatial cognition using time course data analysis of functional Magnetic Resonance Imaging (fMRI). Materials and Methods : To select an item set in the visuospatial performance test, two questionnaires with similar difficulty were developed through group testing. A group test was administered to 263 college students. Two types of questionnaire containing 20 questions were developed to measure the ability of visuospatial cognition. Eight college students (right-handed male, average age of 23.5 yrs) were examined for fMRI study. The experiment consisted of two runs of the visuospatial cognition testing, one with $21\%$ level of oxygen and the other with $30\%$ oxygen level. Each run consisted of 4 blocks, each containing control and visuospatial items. Functional brain images were taken from 37 MRI using the single-shot EPI method. Using the subtraction procedure, activated areas in the brain during visuospatial tasks were color-coded by t-score. To investigate the time course data in each activated area from brain images, 4 typical regions (cerebellum, occipital lobe, parietal lobe, and frontal lobe) were selected. Results : The average accuracy was $50.63{\pm}8.63$ and $62.50{\pm}9.64$ for $21\%\;and\;30\%$ oxygen respectively, and a statistically significant difference was found in the accuracy between the two types of oxygen (p<0.05). There were more activation areas observed at the cerebellum, occipital lobe, parietal lobe and frontal lobe with $30\%$ oxygen administration. The rate of increase in the cerebellum, occipital lobe and parietal lobe was $17\%$ and that of the frontal lobe, $50\%$. Especially, there were increase of intensity of BOLD signal at the parietal lobe with $30\%$ oxygen administration. The increase rate of the left parietal lobe was $1.4\%$ and that of the right parietal lobe, $1.7\%$. Conclusion : It is concluded that while performing visuospatial tasks, high concentrations of oxygen administration make oxygen administration sufficient, thus making neural network activate more, and the ability to perform visuospatial tasks increase.

This study aims to explore the significance of homework help service as a library program to support young people in the community and investigate the characteristics of homework help services in U.S. public libraries. It reviews the previous literature on the cases and trend of homework help services in U.S. public libraries. It also investigates the practice and characteristics of homework help services using an email survey targeting public libraries that offer the services. The results are analyzed in terms of the user, collection, space, public relations and human resources of homework help services. This study may contribute to eliciting the service plan on homework help service in its planning and implementation stage in public libraries.
