디지털 방송 환경의 메타데이타 서비스 중에서도 가장 혁신적인 것이 하이라이트(highlight)메타데이타 서비스이다. 하이라이트 메타데이타를 생성하기 위해서 시각율동을 이용한 샷경계 검출 알고리즘을 사용해 스포츠 경기의 하이라이트 시간구간을 결정하고, 하이라이트 표시기에서 하이라이트를 설명하는 간단한 주제어를 부가한다. 그리고 하이라이트 템플릿을 이용해 계층구조를 생성하고 하이라이트에 부가된 하이라이트 주제어에 따라 계층 구조의 적절한 위치에 삽입하고. 하이라이트 계층구조는 MPEG-7 표준 스키마에 따라 xml로 서술한다 하이라이트 메타데이타 서비스를 받는 시청자들은 매우 짧은 시간에 이미 방영된 스포츠 경기의 중요 장면들을 모두 볼 수 있다.

제 1주제에는 총 106편의 논문이 접수되었으며, 이 논문들의 내용, 성격, 해석방법 등을 정리하였다. 일반적으로 논문의 수준은 모두 우수했으며, 구두발표를 위한 논문을 선정하는데 어려움이 있었다. 해석적인 방법에 있어서는 수치해석 방법이, 계측에 있어서는 직접 계측방법이 가장 일반적으로 사용되었다. 논문 면 수에 제한이 있었기 때문에 대부분의 저자들은 자세한 해석내용을 생략하고 있었다. 특이한 점은 암석역학과 유체동력학과의 접합이라 할 수 있으며, 암반 안전성에 미치는 시간의 영향 등에 대한 연구가 계속적으로 이루어져야 한다.

지난 연구에서는 국립과학관 천체투영관 등에서 사용하는 천체시뮬레이션 소프트웨어를 활용하여 스크립트 제작 및 360° VR 영상 제작기술을 개발하였고, 비대면 환경에서도 개인휴대기기 등을 통한 몰입도 높은 천문학 교육을 구현할 수 있도록 연구를 진행하였다. 계속되는 연구로 천체시뮬레이션을 활용한 교육프로그램의 장점을 잘 나타낼 수 있는 주제들 중 2015 교육과정 중학교 3학년에서 다루는 '우주 탐사 성과와 의의'를 주제로 파일럿 프로그램을 개발 중이며 그 과정을 소개하고자 한다. 개발하는 프로그램은 과학관 천체투영관에 적용하여 실무자의 활용을 지원할 계획이며 다양한 교육콘텐츠 개발에 활용되기를 기대한다.

In order to prepare for changes in future society, cross-curricular learning is emphasized, and the need to link cross-curricular learning topics and subjects is increasing. However, there are few studies on how to deal with cross-curricular learning in mathematics education. This study analyzed the contents and methods of cross-curricular learning topics in subject-specific curriculum and mathematics textbooks. As a result of the study, the curriculum can be categorized into four types according to the variety of cross-curricular learning topics applied and the presence or absence of a main cross-curricular learning topic, and the mathematics curriculum belongs to the type where some cross-curricular learning topics are dealt with passively and there is no main topic. On the other hand, the analysis of 10 math textbooks for grades 5 and 6 according to the 2015 revised curriculum showed that, unlike the curriculum, various cross-curricular learning topics were applied in the textbooks, mainly environment and sustainable development education, safety and health education, career education, character education, and economic and financial education. In addition, in mathematics textbooks, cross-curricular learning topics appeared in various types such as materials, questions, explanations, illustrations, and in many cases, they appeared mainly as materials or illustrations. Based on these findings, implications were explored and suggested on how to integrate and apply cross-curricular learning topics in mathematics.

The STS materials, emphasized in the 6th curriculum, in the chemistry part of middle school science textbooks were analyzed. The average value of the STS content of textbook was 13.2%. In the study of chapter of textbook, 15.9% of STS materials was included in the chapter of ？reaction of materials?, 12% in "character and separation of materials", and 10.8% in "composition of materials". When the STS topics classified by Piel were analyzed, the results were as follows; 40.2% on sociology of science, 28.8% on environmental quality and utilization of natural source, 20.4% on effects of technological developments, and 12.9% on energy. However, the topic on human engineering was only included in a textbook, and the topics on space research and national defence were not included in any textbooks. When the STS materials were analyzed by student activities of SATIS, the number of activities was 71. Most activities were consisted of solving problems and decision, simulation and data analysis, and there was no research design and role playing.

The goal of this study is to build the environmental and geographic information system according to the administrative territory in Gyeongbuk province in order to resolve the mismatch between the environment attribute information and geographic information system. In order to do that, this study reviews the characteristics of local geographic information system and environmental attribute information. After that, this paper tries to figure out the way of integration between geographic and environmental informations using the administrative unit code. The result of this study can provide the basic database for building the environmental policy and improve the reality of policy analysis because this method can provide the environmental attribute database with the administrative territory information. And it will contribute to improve the environmental management system and to build the other attribute databases for the local government.

The purpose of this study is to explore the social perception on geoscience using a big data analysis and to propose a way to enhance people's perception on geoscience. For this, 5,044 media articles including geoscience produced by 54 media companies from January 1, 2010 to April 14, 2022. were analyzed. Big data analyses were applied. The results of analyses are as follows: Media articles consist of key words of research institute, some countries of America, China and Japan, City of Pohang, CEO of KIGAM. And geology, industry, development of mineral resources, environment, energy, nuclear power, and groundwater are highlighted as key words. Also, it is confirmed that topics related to geoscience such as expert, environment and research institute are not individually isolated, but interconnected and linked to topics in the center of future, industry, and global. Based on this result, ways to enhance people's perception on geoscience were discussed.

The purpose of this study is to develop a project-based teaching-learning instruction to solve the problems in family life. The developed process can be a practical plan to activate environmental education centered on living environment problems curriculum of Home Economic Education[HEE]. In order to achieve the purpose of this study, the curriculum of HEE and environmental education categories were compared and analyzed. The study selected 10 themes and developed a project-based HEE teaching-learning instruction with 8 sessions. The characteristics of the developed teaching-learning instruction are as follows. First, HEE curriculum included environmental knowledge, values and attitudes, competence, and practice and participation in environmental education and related categories in achievement standards and learning elements. Second, since HEE curriculum has a teaching-learning instruction plan based on project-based learning that allows learners to recognize and solve problems themselves was developed based on the real life-centered learning themes related to environmental education. It was also proposed that the subject of HEE has a high correlation with environmental competence and environmental practice, and thus environmental contents that can raise students' interests in society and environment should be added to the HEE curriculum. The teaching-learning instruction developed in this study can be used for classes such as HEE classes or free semeste. A follow up study would need to test the educational effects of this teaching and learning plan by implementing it to the actual class.
