가상 현실을 이용한 다양한 응용기술이 등장함에 따라, 그를 이용한 서비스와 상용 애플리케이션이 개발되고 있다. VR, AR 사용자가 증가하고, 주위에서도 쉽게 이러한 기술을 접할 수 있게 되었다. 이에 본 논문은 2D로 표현되는 기존의 지도 사용을 어려워하는 사람들의 문제점을 해결하기 위하여 VA과 AR-based 3D를 통합할 수 있는 지도를 연구하고 'SNUT MAP'을 개발하였다. 'SNUT MAP'을 개발하는 데 Unity 3D와 Dronedeploy, Blender, Vuforia, AR+GPS location, Google maps API를 사용하였다.

클라우드 스토리지는 다양한 리소스에서 인터넷을 통해 데이터를 저장하고 접근하는 형태의 데이터 스토리지를 말한다. 클라우드 스토리지는 서비스 접근성, 용량 조절의 용이성이 높아 꾸준히 사용자가 증가해왔다. 특히 모바일 기기와 연동하여 자동 동기화함으로써 사용자와 관련한 다양한 데이터가 실시간으로 업·다운로드 된다. 이에 따라 클라우드 스토리지에는 디지털 포렌식 관점에서 특정 사실을 증명하거나 사건의 실마리가 되는 중요한 단서가 저장되어 있을 가능성이 크다. 따라서, 본 논문에서는 클라우드 스토리지의 정의와 종류를 살펴보고 디지털 포렌식 관점에서 클라우드 스토리지의 데이터 수집 및 분석 기술에 관한 연구 동향을 분석한다. 또한, 현재 클라우드 스토리지 데이터 수집 기술의 한계를 분석하고 향후 연구 방향에 관해 논의한다.

The purpose of this study was to investigate the effects of implementing semantic mapping reading strategy in the science class on high school students' science text reading ability. 3^rd grade students of science core high school in a small and medium-sized city participated in this study for a semester. Texts with socio-scientific issues and chemistry subjects were used to implement semantic mapping reading strategy in the science class. To investigate the changes in students' science text reading ability, experimental group students participated in the pre-reading and post-science reading ability tests and the results were analyzed. The results of this study showed that the mean of the science reading ability test score of experimental group was significantly higher than that of the comparison group. We found that drawing a semantic mapping before solving a reading task made it easier for students to find information and infer meaning from text. It can be seen that students also recognize that the semantic mapping is helpful in understanding the text because it is easy to understand the relationship between concepts by visualizing the content of the text, and can connect their background knowledge with the text content.

This study recruited 11 teachers with experience in guiding science exhibitions nationwide to investigate the perception and necessity of teachers as educational consumers of science exhibitions, one of the out-of-school science education activities, and conducted an in-depth written survey. An average of more than 3,600 characters answered a total of seven questions in writing, and through qualitative analysis, the growth of students and teachers due to participation in science exhibitions, difficulties in participating in competitions, and teachers' voices for revitalization were recognized. Teachers offered positive opinions in that participation in science exhibitions improves students' knowledge and attitudes related to science and experiences an open inquiry process linked to career advancement in science and engineering. However, the students who participated in the competition failed to record the contents of the inquiry in their school records, and instructors pointed out the obsession with discovering novel topics, the burden of guiding the inquiry process, and the limitations of their expertise in major knowledge. In order to revitalize science exhibitions, 17 city and provincial education offices called for measures to strengthen the capabilities of instructors and students, improve the promotion and screening methods of the National Science Museum, and improve the Ministry of Education's school records.
