The aim of software education is to increase students' Computational Thinking(CT) skills that they can compose problems and provide solutions which can be carried out effectively by information-processing systems. Furthermore, if problem solving situations can provide students with meaningful problem solving opportunities in authentic social contexts, then software education would be more valuable. This study pursued educational robot-based SW convergence education where 4th grade primary students have access to tangible outputs and can engage in authentic problem solving situations working with peers by using robots and programming. In addition, this study investigated the effectiveness of the classes in terms of computational thinking skills and social capabilities(collaborative skills and communication skills). The current study provides educational robot-based SW convergence education cases of a primary school and discusses the effectiveness of the classes in terms of students' computational thinking skills and social capabilities.

산림은 탄소저장능력이 있어 대표적인 온실가스인 이산화탄소를 저감시킨다. 따라서 산림의 탄소저장능력 특성을 규명하고 그것을 산림경영에 반영함으로써 온실가스 저감이라는 국제적 노력에 동참하는 수단으로 활용할 수 있다. 일반적으로 임분에서의 탄소저장능력(Carbon Storage, CS)은 식생탄소저장능력(Vegetation Carbon Storage, VCS)과 토양탄소저장능력(Soil Carbon Storage, SCS)의 합으로 볼 수 있다. 본 연구에서는 우리나라 대표적인 자생수종인 소나무림 VCS의 공간분포를 지엽적 범위(spot level)에서 광역적 범위(regional level)로 확대하여 그 특성을 규명하는 방법을 제시하고자 한다. 지엽적 범위의 조사 및 연구에서 VCS는 임목의 흉고직경(Diameter at Breast Height)과 밀접한 관계가 있는 것으로 확인되었다. 이러한 관계와 Quickbird 고해상도 위성영상에서 추출한 소나무림 공간분포도를 이용해 경관범위(landscape level)에서 소나무림 탄소저장능력의 공간분포를 추정할 수 있었으며,그 결과를GIS 및 RS를 통해 광역적 범위로 확대하였다.

As evolution of multimedia technology brings changes to industries concerned with design, new education program is needed to cultivate designers with abilities which are adapted to changed circumstance. This paper is purposed to show guideline to set up a fundamental course for multimedia design in which students know what are new presentation modes and learn how to use them, Multimedia design call for abilities of organizing information, representing, and implementing interactivity. Among them, fundamental course considers representing information as central subject. And it also contains lessons which are relative to proceeding courses. It should have students to experience creative composition and various expressions, and study cognitive or aesthetic effects of them. All activities are based on the understanding about presentation factors and principles. Basic course's lessons are composed by two main subjects, which are essential expression and matters relative to organization and interactivity. Described in detail, lessons are divided into three phases. First phase is combining presentation factors for affective effects, second is delivering message of various knowledges and third is forming simple interaction.

The purpose of this study is to provide base line data to the educational settings so that more improved occupational core competencies could be taught under the formal curriculum of the technical highschool than before through the inquiry into 'the need for the consolidation of education that principals of technical highschool perceive'. Initial occupational key competencies had been prepared through the literature review on the occupational core competencies and the review on the key competencies by the experts in the field of technical industry had been performed to achieve the purpose of this study. The survey instrument consisting of final 9 occupational key competencies had been developed with the careful consideration for the calculation of the need for the consolidation of education using the Borich's model. The results show that principals for the technical highschool perceive the strong need for the educational consolidation regarding the all 9 occupational core competencies in the whole. However, for the specific key competency of understanding the organization and the mathematical competency, the principals of the technical meister highschool perceive somewhat differently from the principals of the specialized technical highschool. The principals in the meister highschool perceive not much need for the consolidation of education regarding the competency of understanding the organization and the mathematical competency.

This study is to analyze the relationship among potential variables of self-development, social development, learning readiness, and academic ability using data from the Panel Study on Korean Children, which was surveyed in 2014, and to find factors affecting the academic ability of preschool children will be. The subjects of this study were 6-year-old children of 1113 households among 2150 households in the 7th Panel Study on Korean Children(2014) data, excluding non-responders and system-missing 1037 households. As a result of analyzing the path effect of the research model, it was found that, between self-development and academic skills, self-development had a direct effect on academic skills and also had a significant indirect effect through social development and learning readiness as a medium. In addition, it was found that learning readiness had the greatest influence among self-development, social development, and learning readiness on academic skills. As a result, the academic skills of preschool-age children should be treated with great importance in order to develop them into talents with creativity and problem-solving ability.

With the 4th Industrial Revolution, VR/AR technology is developing, and since COVID-19, the use of VR/AR technology is increasing and is being used in various environments. In particular, AR technology can be used in various educational fields and the perception of VR in the educational field and learning satisfaction, problem-solving ability, and self-directed learning ability when using VR were analyzed. It was analyzed that perception of VR and learning satisfaction had a significant correlation at the significance level of 0.001, and problem-solving competency had a significant correlation between learning satisfaction and self-directed learning ability at the significance level of 0.05.

The purpose of this study is to examine how the content components of information literacy textbooks develop and is to find implications for improving of textbook publication. Three kinds of information literacy textbooks were published sequentially over time. The content components of 『Information and media』(1996) and 『Library and information skills』(2011) are processed by filament structure and 『Information and library』(2002) has a topic-driven project activity. Generally, a small lesson unit of the textbook consisted of three components (learning goals, learning contents, learning activities) and each component in the unit have to make semantic close relationships. However, in some information literacy textbooks, there are cases that the semantic relationship between goals, contents, and activities are cut off. This disconnection cases can be a fatal drawback for the reliability of textbooks, so sufficient attention is needed to develop information literacy textbooks later.

지식검색서비스의 사용자들이 많아지면서 정보를 획득하고 전파하는 새로운 방법으로 각광받고 있고 많은 연구가 진행되었다. 그러나 기존의 연구는 단순히 사용자의 만족도에 관한 연구가 대부분이었다. 본 연구에서는 기존의 사용자 만족도에 관한 연구와 더불어 개인이 느끼는 자신의 컴퓨터 활용능력에 따라 지식검색서비스에 대한 만족도가 상이할 것이라는 가정 하에 연구를 진행하였다. 연구결과 만족도에 정보 품질과 서비스 품질, 재미, 웹 사이트 신뢰도가 만족도에 영향을 미치는 것으로 나타났고, 조절 변수로 사용한 자기 효능감은 서비스 품질에 대해서만 조절 효과를 가지고 있음을 확인하였다. 이는 자기 효능감은 정보품질과 재미, 웹 사이트 신뢰도에는 영향을 미치지 않는 것으로 볼 수 있다. 이 연구를 통해서 앞으로 지식검색서비스 사용자 만족도에 대한 연구들이 더욱 활발히 진행되고 사용자들을 유인할 수 있는 컨텐츠의 개발에 도움이 되고 사용자들의 손쉬운 정보 공유와 활용에 더 큰 역할을 할 수 있게 되기를 기대한다.

귀금속 보석 분야의 업무 전산화 이전에는 원시적인 기입식 장부정리로 비효율적인 상품관리와 인적 자원낭비가 심하였다. 그러나 최근 많은 업체들이 전자적인 문서관리 시스템 도입으로 업무능력 향상과 비용절감 효과로 업체의 경쟁력이 높아지고 있다. 이에 따라 기존 텍스트 기반 정보에서 벗어나 멀티미디어 기반의 정보를 요구하고 있으며, 상품 정보의 전자카탈로그(E-Catalog) 시스템 도입으로 실시간 상품 이미지와 정보를 제공해 판매자와 고객 간의 신뢰할 수 있는 정보 제공과 모바일(Mobile)통신의 장점인 이동성, 편재성, 실시간성, 휴대성 등을 활용한 기술개발 및 상품화가 요구되고 있다. 본 논문에서는 모바일 기술을 활용하여 휴대용 단말 장치를 이용한 귀금속 보석분야의 이동성이 보장되는 휴대용 B2B 시스템을 구측하였다.
