본 논문에서는 정보 분야의 학습 능력을 나타낼 수 있는 ICT 리터러시에 대해 지역 규모에 따른 수준의 차이를 측정해 분석하였다. 그 결과, 초등학교에서는 지역규모에 따른 ICT 리터러시 검사의 평균 점수가 대도시, 중소도시, 읍면지역 순으로 높았고 중학교에서는 중소도시, 대도시, 읍면지역 순으로 높게 나타났다. ICT 리터러시 세부 능력요소 및 등급의 차이도 지역규모에 따라 초등학교와 중학교에서 다른 양상을 보이는 것을 확인하였다. 다만, 초등학교와 중학교 모두 읍면지역 학생들의 점수가 다른 지역 학생들의 점수보다 낮은 것으로 나타났다. 이를 통해, 도시지역과 읍면지역 학생들 간에 격차가 발생하고 있는 것을 확인할 수 있었으며, 이를 개선하기 위한 체계적인 교육 프로그램 개발이 필요한 것으로 판단된다. 본 연구는 향후 지역규모 및 학교급별 특성에 따른 체계적인 ICT 리터러시 교육 정책 및 프로그램 개발의 필요성을 위한 기초 자료로서 의의가 있다.

In this paper, According to researches on the effectiveness analysis of digital textbooks for the last three years, it was turned out in digital textbook research school that learners' computer literacy is the most effective factor and the basic ability required to use digital textbooks. Therefore, in this paper, the effects of computer literacy on various factors were analyzed. For this purpose, after the level of learner's computer literacy was divided into upper, middle, and lower, and the effects of each level on cognitive aspects ability(problem solving ability, self-directed learning ability, and critical thinking ability) were analyzed. As a result, It turned out that the learner 's computer literacy has a close correlation with cognitive aspects ability(problem solving ability, self-directed learning ability, and critical thinking ability), and has a significant effect on cognitive aspects ability. In particular, the group with lower level of computer literacy had the greatest influence on the cognitive aspects ability, and the group with upper level had the greatest influence on the cognitive aspects ability in score improvement. Therefore, this paper suggests that various types of computer literacy education are needed to use effective digital textbooks.

Objective : This study was produced to examine the effects of moxibustion that had been played important role to traditional oriental medical treatment on disease. Recently, it was reported that moxi-tar which is generated in the process of moxibustion as burning combustibles decreased NO and iNOS generation in C6-glioma and RAW 264.7 cells in our lab. Methods : C6-glioma cells were cultured in RPMI 1640 with FBS 10% in CO2 incubator. To study the protective effects of moxi-tar, we observed cell viability, DPPH activity, SOD activity, catalase activity and cell morphology after injury with $H_2O_2$. Results and Conclusions : Moxi-tar increased cell viability about twice as much as that of being injury by $H_2O_2$(moxi-tar $40{\mu}g/m{\ell}$, $H_2O_2$ $500{\mu}M$). And the results of free radical scavenger activity($80{\mu}g/m{\ell}$ : $78.91{\pm}4.4%$), SOD activity and catalase activity($80{\mu}g/m{\ell}$ : 21.6unit/mg protein) were increased by moxi-tar as dose-dependent manner. So we concluded that the effects of moxibustion which is played important role in Oriental medicine, might be free radical scavenger effects induced by moxi-tar. Conclusion : These results indicate that tBHP induces apoptosis through a lipid peroxidation-dependent mechanism and JS exerts the protective effect against the apoptosis by preventing peroxidation of membrane lipids.

The good courseware must have the me끼ts of computer and must be designed according to principles of instruction. Therefore, we propose a model of learning structure for tutorial web courseware on the basis of elaboration theory that can give us the suitable design strategies of contents for web courseware. This model is suited to the level learning and individual learning because it is constructed of six factors - epitome, precedence learning, basis learning, depth learning, summarizer, synthesizer. We also make a tutorial web courseware to apply this model and evaluate effects in comparison with the existing tutorial web coursewares. 좋은 코스웨어란 컴퓨터라는 매체가 가진 장점을 최대한으로 살릴 수 있고 수업설계의 원리에 따라 설계된 것이다. 따라서 본 논문에서는 웹이라는 매체의 특성을 가장 잘 표현해 줄 수 있는 정교화 이론에 따라 개인교수형 웹 코스웨어의 내용구조 모델을 제시하였다. 이 모델은 개요정리, 선수학습요소, 기본학습, 심화학습, 요약정리, 종합정리 등의 여섯 가지 요소로 구성되어 있어 수준별 학습이 용이하고 개별학습에 적합하다. 또한, 제시한 모델을 개발에 실제 적용하여 개인교수형 웹 코스웨어를 제작하고, 기존의 개인교수형 웹 코스웨어와 비교하여 효과성을 검토하였다.

Objective: In 1960`s Bonghan Kim`s team found BongHan(BH) ducts which were presumed as acupuncture meridians and BH corpuscles. They asserted Bonghan theory and SanAl theory which was involved in cell division and cell restoration. However, many other experiments which had been operated to demonstrate and find the existence of BH ducts had failed because of the secret of blue stain drugs. During the last several years, BongHan theory has been revived through experimental researches to find the anatomical structures of BH ducts and corpuscles by Soh`s Biomedical Physics Lab. Soh`s research team used the staining with Janus Green B, Alcian blue, nanoparticles and Acridine Orange. We used DAPI staining to find the existence of BH ducts and the corpuscles and to observe nuclear arrangement. Methods: We used japan white rabbits as experimental animals. BH ducts and corpuscles were stained with DAPI. The nucleus configuration in BH ducts stained with DAPI were observed with microscope. Results: In this study, we found thread like structures in silver white color distinguished from the blood vessels, nerves and lymph vessels. These thread like vessels in the linear duct shape were connected to same colored mass in the ball shape. Thread like structures we found could be separated easily from the surrounding other organ mass. The nuclei of the thread like structure in DAPI staining, are about 10~20㎛ length, in rod shape and linear arrangement. Conclusion: We concluded that the thread like structure we found was same vessel reported by Soh`s research team, BongHan ducts and corpuscle.

As online classes started in 2020 due to the COVID-19 outbreak, the use of online content in classes such as e-books, Google tools, and videos has increased. Accordingly, the need for textbooks made by teachers is emerging so that students can learn effectively even in an online environment. In addition, as online classes and student-participatory classes using various online contents expand, teachers are actively using online content-using textbooks as well as book-type textbooks. In other words, it is a time not only to prepare for online classes, but to establish the concept of online textbooks and to think about the system and direction of current textbooks in order to transform into a future education system. Therefore, in this paper, the basic data for establishing the concept of online content utilization textbooks that are currently being introduced have been analyzed and theoretical contents for the development direction of future textbooks to be developed in the future are explored.

초·중학교 SW 심화교육을 위한 가상현실 프로그래밍 도입 가능성 탐색

안성훈 ( Sung Hun Ahn ) 한국창의정보문화학회 2017 창의정보문화연구 Vol.3 No.1

The Ministry of Education announced plans to introduce SW education to elementary and secondary schools in the 2015 curriculum. However, if we examine major foreign countries where SW education strongly implemented it is found that they stress not only coding education but also real life SW education. Especially they emphasized convergence with other different fields. Therefore, it can be concluded SW education in Korea should be differentiated based on levels of students. For the common basic curriculum, it is needed basic concepts and thinking skills of SW development, but for the enriched curriculum, it should be emphasized SW development education that can be applied to real life experiences and other difference fields as well. Therefore, it is necessary to plan SW intensive education to develop programs for the enriched program. In this study, I explored how virtual reality programming education can be applied to the level of elementary and secondary school students as an enrichment program.

In order to establish the correct direction for the use of digital textbooks in the future, it is necessary to derive implications for improving the domestic digital textbook utilization policy by analyzing the actual conditions of other countries that are already using digital textbooks. Therefore, in this paper, we compared the policies of using digital textbooks in the United States, Canada, Malaysia, and China, and reviewed ways to improve Korea's digital textbook policies. First, each country's digital textbook promotion subject and strategy, scope of use, issuance system, and usage method were compared, and then the implications of each country's digital textbook policy were analyzed. And based on these implications, a plan to improve Korea's digital textbook policy was suggested. It is expected that this will be used as meaningful basic data in preparing policies for the development of digital textbooks in the future.
