The purpose of this study was to examine the perceptions of novelty space among pre-service elementary and secondary earth science teachers. We conducted a survey to explore the perceptions of 38 pre-service elementary school teachers at the National University of Education and 31 pre-service secondary earth science teachers at the Department of Earth Science Education at B University. Semi-structured interviews were conducted with 12 participants, including three pre-service elementary teachers and nine pre-service secondary science teachers. In addition to the elements of novelty space, prior knowledge (cognition), prior outdoor learning experience (psychology), familiarity (geography) with outdoor field learning, and social and technical elements were added. When classified based on elementary and secondary levels, there were statistically significant differences in cognitive, psychological, geographic, and social areas for the elements of novelty space. Statistical differences indicated that the experience or capital related to outdoor learning may have resulted from more pre-service secondary earth science teachers than pre-service elementary teachers. In additional interviews, both elementary and secondary pre-service teachers reported that competencies in the technical domain would be emphasized in the future owing to the necessity and the technical development of virtual-reality-based outdoor field learning programs. This study emphasizes the academic significance of novelty space that should be considered to conduct geological field learning for elementary and secondary earth science pre-service teachers while considering the current post-pandemic educational context.

This study analyzed a group interview with six earth science teachers and eight middle school students to find out the evaluations and criteria they use to evaluate VR/AR contents (two virtual reality content and two augmented reality contents) in middle school science digital textbook. The study found the VR/AR contents were evaluated on four criteria as follows: VR/AR media characteristics; technical operation; user interface; and teaching-learning design. The evaluations can be summarized by each criterion. First, regarding VR/AR media characteristics, interesting features of VR/AR contents were considered relatively advantageous compared to other media like videos. However, its shortage of visual presence and inconvenience of using markers were mentioned as shortcomings. Second, in the technical operation criteria, teachers and students found the following conditions as technically challenging: failing to properly operate on a particular OS; huge volumes of contents in the application; and frequent freezing when using the application. Third, poor intuitiveness and lack of flexibility were found as negative aspects in user interface. Fourth, regarding teaching-learning design, the teachers evaluated whether the VR/AR contents delivered scientifically accurate information; whether they incorporated class goals set by teachers; and whether they can help students' inquiry. It turned out teachers gave negative feedbacks on VR/AR contents. The students evaluated VR/AR contents by assessing whether they help them with learning science but concluded they did not regard them necessary in science learning at school. Based on the findings, this study discusses which development direction VR/AR contents should take to be useful in teaching and learning science.

최근 우리 나라에서도 경영합리화와 생산성향상의 문제가 활발하게 논의되고 있고, 또한 이와 동시에 기업을 경영하는데 있어서 계획 및 관리의 필요성이 강조되고 있다. 이와 같이 기업환경의 급속한 구조 변화에 대비하여 본론에서는 생산성향상을 위한 가장 중요한 경영관리 기법중의 하나인 I.E(Industrial Engineering)에 대하여 소개하고저 한다. 본래 I.E는 그 수법이나 대상에 있어서 자연과학이나 사회과학분야에서 활용되고 있었으나 미국의 F.W.Tayler 박사가 이를 최초로 경영학적 측면에 도입, 적용하였다. 1890년대에 미국은 공업생산국으로서 산업근대화에로의 발전과정에서 경영자측은 기술이나 방법에의 개선에 의한 산출량 증가로서 노동자의 임금절하를 기도하고 있는 노동자측은 태업으로 임금문제를 해결하려고 하였다. 따라서 F.W.Taylor 는 산업발전에 최대의 장벽인 임금문제의 기술적인 해결에 주력하여 노사간의 분쟁을 $\ulcorner$성과급임금제도$\lrcorner$로서 조정하기 위해 $\ulcorner$과학적 관리법$\lrcorner$(The Scientific Management)을 체계화시키기 위한 일련의 작업에 착수하였다. 이외에도 테일러는 임금문제에 관련된 생산성 향상 문제까지도 연구발전시켜 생산계획$\cdot$공장관리$\cdot$작업조직$\cdot$자재관리$\cdot$공정관리 등의 전반적인 공장관리 문제를 해결하기 위하여 $\ulcorner$공장관리$\lrcorner$(Shop management)를 발표하여 I.E의 체계를 확립시키는 계기를 마련하였다. 이와 같이 I.E는 미국을 중심으로 발생한 것이지만 그간 우리나라에서도 도입 적용되어 발전되고 있음을 감안할 때 한국양회공업협회가 본기법에 대하여 관심을 갖고 일련의 조사활동을 시작한 것은 매우 의의있는 일이라 할 수 있다.

Stone cultural heritage will either be damaged by composite damage or will lose its original historical authenticity starting with the moment it is created. Various artificial interventions to restore them to their original state have been described, centering on the conservation treatment case of the Stupa of State Preceptor Jigwang from the Wonju Beopcheonsa Temple Site. Restoration of the Jigwang stone pagoda was carried out after securing all scientific and technological means for the research and protection of the cultural heritage in question. Since its restoration was promoted to retain its aesthetic and historical value and was based on a careful understanding of the original materials and prototypes, extensive restoration was sought, which contributed to the restoration of the original form, resulting in both preservation and authenticity.

With the development of information technology, fake news is becoming a serious social problem. Individual measures to manage the problem, such as fact-checking by the media, legal regulation, or technical solutions, have not been successful. The flood of fake news has undermined not only trust in the media but also the general credibility of social institutions, and is even threatening the foundations of democracy. This is why one cannot leave fake news unchecked, though it is certainly a difficult task to accomplish. The problem of fake news is not about simply judging its veracity, as no news is completely fake or unquestionably real and there is much uncertainty. Therefore, managing fake news does not mean removing them completely. Nor can the problem be left to individuals' capacity for rational judgment. Recurring fake news can easily disrupt individual decision making, which raises the need for socio-technical measures and multidisciplinary collaboration. In this study, we introduce a new public online platform for fake news management, which incorporates a multidimensional and multidisciplinary approach based on citizen science. Our proposed platform will fundamentally redesign the existing process for collecting and analyzing fake news and engaging with user reactions. People in various fields would be able to participate in and contribute to this platform by mobilizing their own expertise and capability.

This study aims to analyze the content and methodological aspects of converging scientific technology and humanities in 233 elementary school STEAM programs developed and publicized from 2012 to 2015, to provide the basic materials and implications for editing and supplementing the development of future STEAM programs or policies, or on-site applications of developed programs. The analysis results show that among the Liberal Arts courses of the STEAM program, including Korean, Social Studies, and Ethics, the level of convergence was lowest in Ethics. This seems to be due to the fact that convergence between scientific technology and humanities tended to emphasize a cross-studies convergence over a content convergence done with a specific purpose. In terms of methodological convergence between scientific technology and humanities, the level of convergence of humanities at a normative level was relatively lower than that at a descriptive level. Although a quantitative comparison of the two methods was not significant, it is rather concerning that due to simply converging descriptive humanities, students may not be so aware of the double-sidedness of scientific technology, despite the discovery of some programs that need re-evaluations of their ethical or normative directions. Moreover, the results showed that the cases of converging scientific technology and humanities at a normative level that were analyzed in the STEAM program can be divided into 'complementation of humanities to utilizing scientific technology' and 'complementation of humanities to research in scientific technology and development.' Based on such research results, the study discusses the development of STEAM programs and policies and directions for editing and supplementing programs on-site.
