The purpose of this paper is to examine the change in perception of 3D virtual fashion before and after COVID-19 using big data analysis. The data collection period is from January 1, 2017, before the outbreak of COVID-19, to October 30, 2022, after the outbreak. Big data was collected for key words related to 3D virtual fashion extracted from social media such as Naver, Daum, Google, and YouTube using Textom. After the collected words were refined, word cloud, word frequency, connection centrality, network visualization, and CONCOR analysis were performed. As a result of extracting and analyzing 32,461 words with 3D virtual fashion as a keyword, the frequency and centrality of fashion, virtual, and technology appeared the highest, and the frequency of appearance of digital, design, clothing, utilization, and manufacturing was also high. Through this, it was found that 3D virtual fashion is being used throughout the industry along with the development of technology. In particular, the key words that stand out the most after COVID-19 are metaverse and 3D education, which are in high demand in the fashion industry.

The purpose of this study is to survey the occupational therapists's vocational core competency. Study subjects were 138 occupational therapists and 95 students majored occupational therapy and they participated in the survey about the vocational core ability to confirm the factors about the vocational core ability. As the results of these, both occupational therapists and university students majored occupational therapy felt the need for vocational ability and communication skills, interpersonal relationship skills, and problem-solving skills were found to be important, and that they also possessed them. However, only in the group of students majored occupational therapy showed that technical skills were important, but they did not possess the most. Accordingly, it is necessary to consider a curriculum that can collect knowledge and information on various skills necessary for actual vocational performance as the occupational therapist.

Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.

The values of a organization generate belief and activate participation of community members. Accordingly, it is necessary to find new core values of the school library in addition to access and assistance which are the library's traditional values. This study analyzed the central keywords in the contents of mission and vision appeared in the International School Library Standards and acquired core values being composed of 5 fields such as education, collaboration, access, cultural awareness and sensitivity, and democratic citizenship. As a result of analyses of missions and visions in America, Australia, UK, and Canada School Library Standards, it seems that life-long learning skills, physical access and social responsibility are common core values. America and UK School Library Standards which were revised recently are underlining technology skills, multiple literacies and integrated information literacy curriculum particularly. Ultimately, these core values will be utilized as the directions and basic materials for the establishment of missions and visions for the school library in Korea.

In this paper, both content analysis and Romey analysis were employed to analyze three 'General Computer' textbooks used in commerce and information high schools. The content analysis was employed to study the organization and contents of the textbooks, whereas the Romey analysis to determine the inquisitive tendency of four sections - Text, Data, Activity and Evaluation. The results from the content analysis showed that textbooks differed in the number of subsections, the number of pages in each section, and the number of concepts introduced in each section. Also, results from the Romey analysis demonstrated that the section Text in all the textbooks was written with a low level of inquisitive tendency, but also that they differed in that two other sections Data and Activity in one textbook exhibited a high level of inquisitive tendency while the other section Evaluation in two textbooks did. Using the aforementioned results, we proposed ways to improve the readability of 'General Computer' textbooks.

This study examines the digital divide, one of the main issues in digital media environment, in relation with the digital literacy on the perspective of audience welfare. The study explores the current state of audience welfare policy with regard to the issue of digital divide which can be seen as the dark side of this flourishing digital technology society. The barriers and enablers of the digital divide are discussed with the question of how these factors are related with the digital literacy competence of audience. It has been criticized that both the research efforts and the policy implementations on the digital divide had been set within the limitation of physical access to the digital equipment and technology. Recent studies suggested that the digital divide should be viewed in dynamic interaction of a variety of factors such as psychological dispositions, inner attitudes toward digital media, competence and ability of audiences as well as socio-economic status of individuals. Despite the recent inclusive discussion, however, the role of digital literacy in the digital divide remains unexplored. It should be noted that the question of access is not just to do with equipment, but with skills and knowledge that are required to use equipment. This notion suggests an important implication for the digital divide policy establishment. This study proposes a two-stage solution for reducing the digital divide, in which the first stage focuses on physical access and technology education and the second stage on the digital literacy education.

This paper presented an effective strategy to extract the buildings and to reconstruct 3-D buildings using high-resolution multispectral stereo satellite images. Proposed scheme contained three major steps: building enhancement and segmentation using both BDT (Background Discriminant Transformation) and ISODATA algorithm, conjugate building identification using the object matching with Hausdorff distance and color indexing, and 3-D building reconstruction using photogrammetric techniques. IKONOS multispectral stereo images were used to evaluate the scheme. As a result, the BDT technique was verified as an effective tool for enhancing building areas since BDT suppressed the dominance of background to enhance the building as a non-background. In building recognition, color information itself was not enough to identify the conjugate building pairs since most buildings are composed of similar materials such as concrete. When both Hausdorff distance for edge information and color indexing for color information were combined, most segmented buildings in the stereo images were correctly identified. Finally, 3-D building models were successfully generated using the space intersection by the forward RFM (Rational Function Model).

This paper aims to explore what we can improve in the curriculum, teaching-learning, and evaluation on the bases of the analyses of multiple-choice items set in National Assessment of Educational Achievement. For this goal, by using the distribution curves of the responses percentages, we will grasp the features of educational achievement which appear to students through an in-depth analysis about not only item itself but also the contents included in particular distracters. These analyses provide more information than the descriptive statistical values such as the mean of correct answer percentage and the discrimination of whole group and the mean of responses percentages of replies of subgroups. Because the distribution curves of the responses percentages reveal the transition from the lowest to the highest educational achievement very well. From these analyses we acquire the implications about the concept of prime factor or prime factorization, ratio(proportion) such as velocity, linear function, volume of cone, properties of solid figure, and probabilities of empty event and total event.

This paper implements the graphic service template authoring tool based on the service template object model of describing the meta information of the services for early childhood education in the semantic web service environment. Our proposed system provides the robot services by constructing web services automatically and making the appropriate service plans. Moreover, it can create, append, delete, and update the service templates of URC based on STDL, and provide the graphic function on service template resources. In order to provide the user friendly environment in the service template phase, we implement the various editing environment : flow view style, grid view style, and text view style. We also provide the easy editing function by realizing abstract service block based on the robot API. Finally we can offer the intelligent and autonomous service of service agent based on semantic information.
