This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.

In various fields such as art, design, music, film, sports, games, and fashion, NFTs (Non-Fungible Tokens) are creating new economic value through trading platforms dedicated to NFT art and content. In this article, I analyze the current state of blockchain technology and NFT art content in the context of an expanding market for blockchain-based NFT art content in the metaverse. I also propose several tasks based on the economic and industrial logic of technological innovation. The first task proposed is to integrate cultural arts on blockchain, metaverse, and NFT platforms through digital innovation, instead of separating or distinguishing between creative production and consumption. Before the COVID-19 pandemic, there was a clear separation between creators and consumers. However, with the rise of Web 3.0 platforms, any user can now create and own their own content. Therefore, it is important to promote a collaborative and integrated approach to cultural arts production and consumption in the blockchain and metaverse ecosystem. The second task proposed is to align the legal framework with blockchain-based technological innovation. The enactment and revision of relevant laws should focus on promoting the development of the NFT trading platform ecosystem, rather than merely regulating it for user protection. As blockchain-based technology continues to evolve, it is important that legal systems adapt to support and promote innovation in the space. This shift in focus can help create a more conducive environment for the growth of blockchain-based NFT platforms. The third task proposed is to integrate education on digital arts, including metaverse and NFT art contents, into the current curriculum. This education should focus on convergence and consilience, rather than merely mixing together humanities, technology, and arts. By integrating digital arts education into the curriculum, students can gain a more comprehensive understanding of the potential of blockchain-based technologies and NFT art. This article examines the digital technological innovation such as blockchain, metaverse, and NFT from an economic and industrial point of view. As a limitation of this research, the critical mind such as philosophical thinking or social criticism on technological innovation is left as a future task.

The electrochemical performance of Li-S cells was investigated in various ternary electrolyte solutions composed of 1,2-dimethoxyethane (DME), tetra(ethylene glycol) dimethyl ether (TGM), and 1,3-dioxolane (DOX). The discharge capacity values and cycle data obtained at each composition were statistically treated with the Minitab program to obtain mixture contour plots, from which the optimal composition of the ternary solvent systems was predicted. The discharge capacities and capacity retention were quite dependent on the electrolyte composition. It was estimated from the contour plots of the capacity at 1.0 C that the discharge capacity sharply increased with a decrease in the TGM content. High capacities greater than 900 mAh/g at 1.0 C were expected for the electrolyte composition with a volume ratio of DME/TGM/DOX = 1/0/1. In contrast, it was predicted from the mixture contour plot of the capacity retention that the cycle performance would significantly increase with an increase in the DME content.

본 연구는 사이버교육의 활성화와 발전을 근본적인 목적으로 하면서, 원격대학을 중심으로 콘텐츠를 상호 교환하여 활용할 수 있는 체제 및 방법으로 기술 표준화를 제안하고자 하였다. 원격대학의 콘텐츠 교류를 위한 기술 표준화의 모색은 비단 원격대학에만 한정되는 문제는 아니다. 그것은 사이버교육을 수행하고 있고, 다양한 콘텐츠를 개발하여 관리를 해야 하는 주체라면 동일한 문제에 봉착하고, 기술 표준화에 대해 인식을 같이하리라 예상되기 때문이다. 이를 위해 본 연구에서는 원격대학이 당면하고 있는 콘텐츠의 공동활용 방안을 모색하고, 이미 진행되고 있는 콘텐츠의 개발 관리 측면에서 효율성을 기하는 방안을 제시하였다.

The language and the gestures of a teacher, generally, have a great influence on the effect of a lesson. This is because subject content is transferred to students by teachers' language and gestures. In the science lessons which focus on experiments, the language and gestures of both students and teachers will help the learning of scientific content. However, the role of gestures, despite its importance, has rarely been investigated in science education research. The role of gestures of students and teachers is a much needed area of study. This study investigated the gestures observed in the experimental process performed by students who participated in a science exploration activity. Students' gestures play an essential role in the successful performance of the experiment. and they could function as a process of solving the contradictory situation. In addition, the demonstration and the communication of gestures should be performed very cautiously. There were a number of implications for the long-standing problem of the relation between the understanding of science concepts and the performance of experiments.

In this study, we created, implemented, and evaluated the impact of proportional reasoning authentic investigative activities on the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers. For this purpose, a special teaching model was developed, implemented, and tested as part of the pre-service mathematics teacher training programs conducted in Israeli teacher colleges. The model was developed following pilot studies investigating the change in mathematical and pedagogical knowledge of pre- and in-service mathematics teachers, due to experience in authentic proportional reasoning activities. The conclusion of the study is that application of the model, through which the pre-service teachers gain experience and are exposed to authentic proportional reasoning activities with incorporation of theory (reading and analyzing relevant research reports) and practice, leads to a significant positive change in the pre-service teachers' mathematical content and pedagogical knowledge. In addition, improvement occurred in their attitudes and beliefs towards learning and teaching mathematics in general, and ratio and proportion in particular.

The purpose of this study was to examine the impact of the application of a creative thinking technique for development on the creativity and attitude toward science of the students in elementary school. In order to better assist students' levels of creative thinking process, creative thinking techniques were reorganized based on the features of creative learning content in science textbooks. Furthermore, related units from an elementary science textbook were analyzed to map out the lesson plans. The findings of the study were as follows. First, the creative thinking technique developed in this study could be applicable to teaching-learning activities. When a creative thinking technique is applied, that should carefully be selected in consideration of all the creativity elements to be covered in class, and that should be used in a manner to be covered in class, and that should be used in a manner to be appropriate at learner level. Second, the utilization of the creative technique turned out to have a good impact on boosting the creativity of the elementary schoolers. Third, the utilization of the creative technique turned out to exert a good influence on fostering the school children's attitude toward science.
