This study presents the process and outcomes of developing mathematical-informatics linkage·convergence class materials, based on previous research findings that indicate a lack of such materials in high schools despite the increasing need for development of interdisciplinary linkage·convergence class materials In particular, this research provides insights into the discussions of six teachers who participated in the same professional learning community program, aiming to create materials that are suitable for linkage·convergence class materials and highly practical for classroom implementation. Following the material development process, a theme-based design model was applied to create the materials. In alignment with prior research and consensus among teacher learning community members, mathematics and informatics teachers developed instructional materials that can be utilized together during a 100-minute block lesson. The developed materials utilize societal issue contexts to establish links between the two subjects, enabling students to engage in problem-solving through mathematical modeling and coding. To increase the validity and practicality of the developed resources during their field application, CVR verification was conducted involving field teachers. Incorporating the results of the CVR verification, the finalized instructional materials were presented in the form of a teaching guide. Furthermore, we aimed to provide insights into the trial-and-error experiences and deliberations of the developers throughout the material development process, with the intention of offering valuable information that can serve as a foundation for conducting related research by field researchers. These research findings hold value as empirical evidence that can explore the applicability of teaching material development models in fields. The accumulation of such materials is expected to facilitate a cyclical relationship between theoretical teaching models and practical classroom applications.

This study attempts to look at the role that modern Christianity should play on an educational level in order to effectively prepare for the future society in the era of the fourth industrial revolution. In the coming era, various areas of human life, including human labor, are expected to be replaced by AI robots. As new alternatives, the ability to empathize effectively and educate creatively to help develop personality qualities are proposed in a rapidly changing world of uncertainty. Modern Christianity, however, has the responsibility to help solve the problems facing this era in the public as a member of the community beyond the boundaries of the church. The purpose of this study is to examine what education the modern Christianity can present to the world as a public discourse and how that should be done. This study suggests the following points on the proper education for which Christianity will participate in the era of the fourth industrial revolution. First, it is necessary to emphasize a sense of belonging through a sense of community. Second, serious considerations and preparations for education that develops creativity are needed. Third, it is necessary to establish an educational direction that encompasses the entire generation. Fourth, practical education through digital utilization should be implemented in the local community. Finally, Christianity in the era of the fourth Industrial Revolution needs to be more integrated. As the Christian community recognizes that the agenda of the community is its task, it will be able to create a co-existing and symbiotic society.

원격강의 방식은 일반 면대면 수업 방식과 비교할 때 교수자와 학습자의 실시간 질의응답이 잘 이루어지지 않는 점과 학습자의 흥미도와 집중도를 높이기 어려운 단점이 있다. 이러한 단점을 보완하기 위하여 일부 웹사이트에서는 메신저 등을 사용하기도 하지만, 키보드에 익숙하지 않은 학습자는 학습 도중에 키보드를 통해 질문을 하는데 많은 어려움을 겪을 수 있다. 그러나, 실시간 음성과 화상통신(H.323)과 SIP을 사용하면 교수자와 학습자간에 또는 학습자와 학습자들 간의 질의응답을 보다 편리하게 처리한 수 있고 공동체 활동을 활성화 할 수 있다.

This study is purposed to prepare students in theological universities so that they contribute to their faith community as well as the broader social community in future through developing a practical course model for education of character formation. Facing the challenge of a high-tech revolution being progressed globally in this period, theological seminaries as the Christian-affiliated institute of higher education see the necessity to nurture their learners' competency of holistic personality comprehending cognitive, affective, behavioral, and more spiritual maturity as well as specialty in each subject matter. The holistic character capability of seminarians is closely related not only to their own self-realization, but also social community's well-being. This research had the following content and results. Chapter 1 brought up a subject to educational needs of the holistic character formation in the theological seminaries to meet the rapidly changing times. Chapter 2 considered the importance of character formation in the curriculum of the universities and theological seminaries in the times of high-tech revolution through the literature reviews related to. Chapter 3 clarified the elements of character education to be placed emphasis on theological seminaries and established the way of course planning. Chapter 4, using a course of Christian social education for illustration, described in order the whole process of course planning comprehending the need of planning, description of course concept, establishment and definition of learning outcomes, organization of learning experience(course content), teaching-learning activities, evaluation of learning outcome, and course improvement, which was visualized with the chart of the process of course design. Also, it provided a practical illustration of the conceptual map, an outline of content and an organization of units, and scope-sequence chart. Finally, chapter 5 gave an syllabus example in an integrative and digestive form as the course plan to be distributed to the students, which is the final result produced through the whole process of course planning. This research is intended not to present a overall curriculum planning of the university-level in the theological seminaries, but to develop a course-level curriculum focused on the formation of character. The author hope that this study would be used as a guideline in developing a course model to nurture the capability of the learners' holistic character.

Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

A numerical analysis model capable of predicting the shape, the size and the potentiality of collapse of tetrahedral blocks considering the persistence obtained from the field survey of joint distribution around the underground excavation surface has been developed. Numerical functions of analyzing both the exposed trace distribution on the excavation surface and the formation of tetrahedral block controlled by the extent of joint surface have been established and linked to the previously developed three dimensional deterministic block analysis model. To illustrate the reliability of advanced numerical model the case of underground excavation in which the collapse of rock block had practically taken place was studied. Representative orientations of joint sets was determined based on the joint distribution pattern observed on the excavation surfaces. The formation of block on the roof of underground opening was analyzed to unveil the potential tetrahedral block the shape of which was very similar to the collapsed rock block. Mechanisms of collapse process has been also analyzed by considering the three dimensional shape of tetrahedral block.

The purpose of this study was to find out the usage of animation and its relation to the social values and clothing behaviour of adolescents. A survey was conducted in four different high schools in the metropolitan area (Seoul) and 187copies were analyzed by SPSS 12.0 package. The results were as follows; First, According to Usage survey, a number of adolescents watched animations mainly through the internet and 39% of them used the internet $2{\sim}3$ times a week. The most watched genre of animation was action/science-fiction but some differences were observed between male students and female students. Male students enjoyed action/science-fiction, comedy and drama/romance, whereas female students enjoyed drama/romance, action/science-fiction and comedy in the decreasing order. Second, It was found that the favorite genre of animation by adolescents had influence on their community mind and materialism. The most significant genre affectingcommunity life was drama/romance and the one affecting materialism of adolescents was action/science-fiction. Third, Materialism had a significant influence on clothing conformity and the next was community mind. Only materialism proved to be a significant variable affecting fashion followers. In conclusion, the results of this study showed that the adolescents' community life and materialism were significantly influenced by their favorite genre of the animation, and their social values were related to their clothing behaviors.
