The recent COVID-19 pandemic is threatening human life and well-being, causing pain that has not been experienced before. Human security was summoned again as a result of the COVID-19 pandemic. However, it is paradoxically a threat to human security due to its inherent limitations and authoritarian control model. This paper first raises the analytical rigor of the concept of human security, focusing on COVID-19. Based on this, the practical usefulness of human security is improved by constructing a practical model that reflects the human security issues raised in reality. In particular, we approach the COVID-19 pandemic not from a natural disaster, but from the perspective of an artificial catastrophe caused by immorality and division in the international community. At the same time, we propose a multilateralism governance model that reflects the perspective of emerging security in order to realize human rights, the fundamental value of human security, and quarantine, a practical task in a balanced way.

Because the specific security technology alone can not cope with sophisticated attacks, various security management models are applied. But, they do not focus on the vulnerability of the highest part because they offer so many common security management criteria. By analyzing the main information and confidential leakage cases inflicting enormous damage to our society, we found that attackers are using mainly an interface vulnerabilities - the paths that connect the internal and external of the organization, such as e-mail, web server, portable devices, and subcontractor employees. Considering the reality that time and resources to invest in security domain are limited, we point out the interface security vulnerabilities the possibility of attackers to exploit and present a convergence method of security measures. Finally, based of ROI(Return on Investment), we propose the real-time security management system through the intensive and continuous management.

Mobile computing has become a reality thank to the convergence of two technologies :powerful portable computers and the wireless networks. The restrictions of wireless network such as bandwidth and energy limitations make data broadcasting an attractive data communication method. This paper addresses the clustering of wireless broadcast data for multipoint queries. By effective clustering of broadcast data the mobile client can access the data on the air in short latency In the paper we define the data affinity and segment affinity measures. The data affinity is the degree that two data objects are accessed by queries, and the segment affinity is the degree that two sets of data (i.e segments) are accessed by queries Our method clusters data objects based on data and segment affinity measures we show that the performance of our method is scarcely infuenced by the growth of the number of queries.

The objectives of this study are to investigate core learning ability necessary for the 21st century and to develop core human resources required for social and national development in the future. The '21st Century Learning Ability Project' is to approach the existing knowledge and learning multidisciplinary and interactively based on the learning ability of each learner and individually and socially valuable themes. Even in Korea, a variety of intersubject integrative educational curriculum was attempted to cultivate learning ability. However, there are not enough teachers who can teach the differences between the content and characteristics for each subject by fully understanding them. Thus, it is difficult to apply them easily to the field of education. Thus, this study develops the multidisciplinary customized educational curriculum in order to develop the learning ability necessary for the 21st century, analyzes the reality of the educational curriculum integrating the academic knowledge in order to support this effectively. As a result, this study offers the interdisciplinary customized integrated model applicable to elementary and middle schools.

Lil Miquela, who appeared on social media in 2016, is one of the most popular virtual influencers. In particular, Miquela is having a great impact on society by continuing to collaborate with many fashion brands through Instagram. As the activity of virtual influencers is emerging today, this study aims to derive the meanings of contemporary fashion through analyzing Miquela's social media case. This study analyzed Miquela's Instagram posts as research subjects. As a result of the above analysis, it was possible to classify the methods and devices for expressing fashion in Miquela's social media into three categories: storytelling, reality, and tags & hyperlinks. In addition, the meanings of fashion could be derived from three aspects: the object of experience, the direction of technology, and the realization of the spirit of the times. After appearing on social media, Miquela, who has gradually expanded her domain, is a virtual fashion influencer who has built her identity through fashion, and is expected to give new meaning to fashion in the future.

Recently as a result of covid 19, it has emphasis on the importance of non-contact. VR content has been attracting attention as an alternative to visual arts, media art, new media exhibitions and performances with limited offline activities. Although interest in 360 VR video contents such as VR contents for exhibitions and performances is increasing, research on immersion and satisfaction is focused on games and animation VR contents. In this paper, it verified the effect of the difference in the position and height of the VR camera in exhibitions and performances on the user's presence and satisfaction. For this experiment, the presence and satisfaction were measured after experiencing the VR contents of the convergence exhibition and performance filmed at different locations and heights. As a result of the experiment, the difference of VR camera's position had a significant effect on presence and satisfaction, the difference of VR camera's height had a significant effect only Realistic immersion of the presence.

With the development of information and communication technology, the demand for indirect experience contents using realistic media is increasing. It is important to keep the overall concept of the models consistently in order to immerse in the contents while watching realistic media. In the case of realistic media that provides an indirect experience of tourist attractions, modeling should be done by reflecting the actual information of the sites in order to provide an accurate experience. In this paper, we propose a three-dimensional modeling method of islands, representative tourism resources of the southern coast, by reflecting actual data. Since the proposed method is performed according to a structured procedure, it makes it easy to maintain the visual consistency of the entire model when several people work together. Implementation results show that the proposed method produces more realistic results than the modeling method using height information simply.

Seafarers play an important role in shipping and logistics. However, seafarers are relatively vulnerable to mental illness because they have to board ships for a considerable period of time and work in isolation. In particular, in the pandemic situation caused by COVID-19, the crew change is delayed due to the closure of many ports around the world, increasing the mental burden on seafarers. The mental health management of the crew is important because these mental problems can lead to major accidents of lives and ships. This paper identified the necessity of mental health management of seafarers through a survey and identified problems with the currently operated mental health management program and curriculum. Especially, this study proposed VR-based programs to help crews receive mentally counseling treatment in a timely manner and to reduce the mental burden on them by preventing sensitive personal information exposure. Through this, it is expected to contribute to the stable development of the logistics industry by establishing a safe seafarers working environment.
