In this paper, we propose u-learning hub site systems which are designed and implemented based on learning activities oriented components. The proposed systems are composed of component which can process the functionalities for coming into action of learning activities through various devices. Specially, each component is broken into class units by which learning activities of users can be performed on various devices. When users try to connect u-learning system in hub site, the system explores devices of users and connection program and then selects components that are fit to the activities and combines them in realtime. Through the methodology of u-learning hub site, the system proposed in this paper provides u-learning environment so that users can use the learning activity services taking no influence on time, place, devices and programs under the consistent system. That is different to traditional e-learning system which cannot support various devices of users directly.

A maximum of 3 km thickness of sediments were deposited above basement deformed by volcanic activities around the Dok Island. As the geological structure, the tension caused the basement-involved normal faults in the early stage of basin formation, whereas the sediment layers showed normal faults, volcanic domes and sills caused by volcanic activities. From the distribution of volcanics in order of age at the Ulleung Basin, volcanic activities were increased toward the northeastern direction (toward Dok Island). The study area is characterized by extensional crustal deformation before sediment deposition during the Early or Middle Miocene age, After the Late Miocene age, the basin was deformed by deep buried volcanics or subsidence of basin, in consequence, became complex geological structures.

In this paper, a variable motion estimation scheme based on HBMA(Hierarchical Block Matching Algorithm) to improve the performance and to reduce heavy computational and transmission load, is presented. The proposed algorithm is composed of four steps. First, block activity for each block is defined using the edge information of differential image between two sequential images, and then average block activity of the present image is found by taking the mean of block activity. Secondly, camera pan compensation is carried out, according to the average activity of the image, in the hierarchical pyramid structure constructed by wavelet transform. Next, the LUT classifying each block into one among Moving, No Moving, Semi-Moving Block according to the block activity compensated camera pan is obtained. Finally, as varying the block size and adaptively selecting the initial search layer and the search range referring to LUT, the proposed variable HBMA can effectively carries out fast motion estimation in the hierarchical pyramid structure. The cost function needed above-mentioned each step is only the block activity defined by the edge information of the differential image in the sequential images.

The purpose of this study is to develop learning materials and teaching model for the gifted, and to examine the improvement of creativity of them in middle schools. Subjects were 126 gifted students, who were the 7th or 8th graders and have been taught in gifted classes of the adjacent Education Institute for the gifted of Boryeong Education Districts, Chungnam Province Office Of Education. Divisions of gifted Classes were logical reasoning, mathematics, foreign language, science. After the instruction of project-based task, gifted students had improved creativity. Especially, instruction using project-based task was more effective on scientifically gifted students. Most gifted students were satisfied with the instruction using project-based task, and attractive in it. Finally, it was suggested that the instruction using project-based task should be actively used for the gifted students.

This paper applies an active period based bottleneck detection method to flow shop manufacturing system with limited buffer size. Manufacturing systems are constrained by one or more bottlenecks which degrades the system throughput. Conventional bottleneck detection methods include the waiting time or queue length of production stations and their utilization. Due to the random events such as production time of items, machine failure and repair times, the systems may change over time, and subsequently bottlenecks shift from one station to another station. Active period of working station may cause other stations to wait for productions. Information when and where active periods occur helps to find bottlenecks in production systems. Based on these informations, we predict bottlenecks in applying AweSim simulation language. We compare the simulation results of conventional methods with those obtained from duration of active period method, and duration ratio method of both sole and shift bottleneck periods. Even though simulation results are from simple flow shop model, they are quite promising for predicting bottlenecks of production stations. We hope this study aids in decision making regarding the improving system production yield and allocation of available resources of system.

In order to strengthen the core competencies of architecture, not only the curriculum should be reorganized practically, but also various extracurricular activities should be developed so that they cultivate various competencies required for architecture accreditation. In this paper, by surveying competency-based curriculum-extracurricular activities convergence educational system established in D university, strategy to increase students' participation in extracurricular activities is proposed. As a result of the questionnaire survey of the students and representatives of the local architectural designers, the programs to enhance student's creativity, such as contest participation and license certification program, were found to be the most effective extracurricular activities which help to develop the learning capability in architect as well.

This study aims to identify the current status of the village citizen archivist training program (hereinafter "training program") and propose a competency-based training program operational model to improve it. With the steadily increasing number of training programs, revitalizing programs and systemizing operations become imperative. This study focuses on achieving the program's goals, the competence of village citizen archivists, and the continuity of training programs and archiving activities. To this end, the meaning and role of village citizen archivists were investigated through domestic and international literature. Moreover, the current status of training programs from 2015 to 2023 was identified, and the implications of literature reviews and case studies were verified through interviews with the program educators. The implications of the interview were summarized as the program operational plan for each goal, the competence of village citizen archivists, and the development plan, thereby being reflected in the operational model. The competency-based education program operational model was proposed to incorporate a model structure, design principles, curricular modules for each goal, and considerations for each stage of education program operation.

세계는 군사패권주의에서 과학기술에 의한 기술패권주의로 국제질서의 개편이 이루어지고 있으며, 이로 인하여 선진국간 기술블럭화 등 기술이기주의가 심화되고 있다. 일찌기 과학기술 선진국들은 연구개발활동의 성패를 좌우하는 핵심요소인 기술정보의 중요성을 인식하고 1950년대 이래로 국가적 차원에서 정보의 수집, 분석, 가공, 유통체제를 구축해 오고 있다. 이에 비해 우리는 1980 년대 중반 이후 국가적 차원의 기술정보관련 활동을 추진해 오고 있으나 아직도 보유 정보량의 절대부족, 정보활동 및 지원 미흡, 과학기술전담 정보자료센터의 부재, 공동활용에 대한 인식 부족 등이 문제점으로 남아 있다. 이러한 문제점에도 불구하고 2000년대 과학기술선진국으로 진입하기 위하여 우리는 단 기간내에 선진국과 대등한 과학기술정보 보유국으로 발전할 수 있는 체제의 정비는 물론, DB구축 및 유통체제의 확립을 통한 연구개발의 생산성 제고 등 전체적인 과학기술혁신의 기반을 조성하는 것이 필요하다. 이를 위하여 국내외 정보수집체계확립, 심도 있는 정보의 조사분석, 양질의 DB구축, 정보유통 및 서비스체제를 이룩하여야 하며, 정부의 정책적 지원과 함께 과학기술관련 출연 연구소가 종합적인 정보기능을 충실히 수행하여야 할 것이다.

2007년 허베이 스피리트호 사고와 2010년 천안함 사고에서와 같이 사고시 초기대응과 구조체계의 미흡으로 인한 심각한 해양오염사고와 인명피해를 초래하였다. 해양사고 발생시 현장의 비상대응체계의 부족, 혼란 등으로 인한 구난활동의 지연으로 피해규모가 확산될 수 있으며, 구난장비를 포함한 예선의 신속한 지원이 구난의 핵심으로 판단된다. 선진국에서는 장기간의 연구개발을 통한 수준 높은 기술과 첨단장비를 통해 전세계 대형 해양사고에 참여하고 있으나, 국내 민간 선박구난업체는 자체적으로 기술력을 확보할 수 있는 기술적, 재정적 기반이 취약한 상황이다. 따라서 최근에 실시된 국내의 대표적 구난활동 사례를 분석하여 문제점과 향후 개선방향을 제시하였다.
