Recently, Information and Communication Technology and SMART Phone Technology have been rapidly developed. According to the increase of data use, the era of big data has come. With the approach of non-contact society, QR Codes are becoming inseparable in our lives. In this paper, we are trying to figure out the implications of QR Code research based on Big Data in Korea. The purpose of this study is to first examine the previous studies on "QR Code" and conduct an analysis on keywords by field using Big Data. Second, for data visualization WordCloud analysis and network analysis are performed on "QR Code" frequent keyword. Third, we would like to present the research direction to future researchers regarding "QR Code". In the results, First of all, research trends showed that research is on the rise and that various fields are being utilized. Second, the results of the analysis of frequent keyword resulted in similar results overall, with some differences depending on the field and year. Third, we found that the visualization results according to the frequent keyword were also analyzed in the same way as the frequent keyword analysis results. The practical implications of the theoretical findings are as follows. First, 'QR Code' needs to be studied as a means of information delivery, not as a technical aspect. Second, it can be seen that "QR Code" is developing reflecting social trends or issues. With both theoretical and practical implications, we are trying to provide the strategic ways of QR-code in future.

With the recent advent of the New Normal era, realistic technologies and non-contact technologies are receiving social attention. However, the hair styling field focuses on the direction of the hair itself, individual movements, and modeling, focusing on hair simulation. In order to create an improved practice environment and demand of the times, this study proposed a non-contact hair styling VR system. In the theoretical review, we studied the existing cases of hair cut research. Existing haircut-related research tend to be mainly focused on force-based feedback. Research on the interactive haircut work in the virtual environment as addressed in this paper has not been done yet. VR controllers capable of finger tracking the movements necessary for beauty enable selection, cutting, and rotation of beauty tools, and built a non-contact collaboration environment. As a result, we conducted two experiments for interactive hair cutting in VR. First, it is a haircut operation for synchronization using finger tracking and holding hook animation. We made position correction for accurate motion. Second, it is a real-time interactive cutting operation in a multi-user virtual collaboration environment. This made it possible for instructors and learners to communicate with each other through VR HMD built-in microphones and Photon Voice in non-contact situations.

The aim of this study is to provide basic data for college life adaptation support measures at the college level by identifying college life adaptation status, the relevance of university life adaptation and the core competencies. In order to ahieve this aim there are three objectives. This study is a research study to understand the relationship between college life adaptation and core competencies of college students before and after the coronavirus. The subject of this study was 171 university students from Seoul, Gyeonggi, and Honam. Data was collected through an untact questionnaire, and data analysis was performed using the SPSSWIN 25.0 program for mean, descriptive statistics, frequency analysis, T-test, correlation, and regression analysis. As a result, first, the difficulty of "emotional adaptation" before the coronavirus was high, and the difficulty of "academic adaptation" was high after the coronavirus. Second, the core competencies of college students were highest in the order of 'interpersonal relationship competency', 'problem solving competency', and 'information communication competency'. Third, as a result of analysis of the relationship between core competency factors and adaptation to university life, difficulties in social adaptation were found both before and after the coronavirus. After the corona, difficulties in adapting to school and learning new skills appeared. In conclusion, in order for university students to adapt to university life in the post-corona era, university-level support is needed to reinforce interpersonal relations competencies in unrect situations, reinforce information and communication competencies to promote academic adaptation, and reinforce new skills acquisition competencies.

In 2020, civilized society's overall lifestyle showed a distinct change from consumable analog media, such as paper, to digital media with the increased penetration of cloud computing, and from wired media to wireless media. Based on these social changes, this work examines whether the use of computer media in the field of landscape architecture is appropriately applied. This study will give directions for new computer media classes in landscape architectural education in the 4th Industrial Revolution era. Landscape architecture is a field that directly proposes the realization of a positive lifestyle and the creation of a living environment and is closely connected with social change. However, there is no clear evidence that landscape architectural education is making any visible change, while the digital infrastructure of the 4th Industrial Revolution, such as Artificial Intelligence (AI), Big Data, autonomous vehicles, cloud networks, and the Internet of Things, is changing the contemporary society in terms of technology, culture, and economy among other aspects. Therefore, it is necessary to review the current state of the use of computer technology and media in landscape architectural education, and also to examine the alternative direction of the curriculum for the new digital era. First, the basis for discussion was made by studying the trends of computational design in modern landscape architecture. Next, the changes and current status of computer media classes in domestic and overseas landscape education were analyzed based on prior research and curriculum. As a result, the number and the types of computer media classes increased significantly between the study in 1994 and the current situation in 2020 in the foreign landscape department, whereas there were no obvious changes in the domestic landscape department. This shows that the domestic landscape education is passively coping with the changes in the digital era. Lastly, based on the discussions, this study examined alternatives to the new curriculum that landscape architecture department should pursue in a new degital world.

The purpose of this study is to examine COVID-19 situation in temrs of war-theory and to find out ways to overcome it. Just as the war changes the paradigm in the international situation and the national crisis management system, the current COVID-19 pandemic is bringing about the entry of the so-called "New Normal" era having the characteristics including untact culture. Although academic research on COVID-19 is mainly dealt with in terms of medical, tourism, and economics, the military research has not yet begun from the perspective of military science or war theory. In the concept of a comprehensive crisis that COVID-19 can cause enormous damage to the life and property of a country, it can be regarded as a target or enemy to be overcome. Among various war theories, the similarities with COVID-19 incident are analyzed in terms of the nature and aspect of the war and the factors of victory. Qualitative and questionnaire analysis results show that the COVID-19 outbreak is very similar to war when considering a variety of war-characteristics. In addition this research proposes ways to overcome COVID-19 based on the victorious factors of the past war, and predicts the impact of the international community after the end of COVID-19 pandemic. As a result of analyzing the priority of overcoming factors through the Analytical Hierarchy Process (AHP) shows that clear goals and establishment of alliances should be prioritized for successfully overcoming COVID-19.

This study analyzed the most frequently used navigation cases in a desktop environment. As a result of the research, GNB induces users' search as the top element of the search structure and can place color, text, icon, and image elements. LNB could be classified in the form of a dropdown, flyout, dropline and mega menu. In this study, the navigation structure of Interpark and Interpark among open markets used by users was analyzed. G-Market's GNB has a two-tier structure with color, text, image, and icon elements, and Interpark has a three-tiered horizontal label. Interpark's GNB drew attention by placing a badge on the seasonal label, which is a temporary content section, unlike G-market. It can be seen that the LNBs of both shopping malls have flyout menus that protrude when you mouse over the category menu arranged in a vertical text form under the logo placed on the left. The flyout menu has a complex structure consisting of the layout of the mega menu. This study is meaningful in revealing user experience elements by analyzing the GNB and LNB of shopping malls these days where internet shopping is increasing.
