Private security organizations are complementary to the national safety of life and property of individuals as a social role to play in maintaining peace and order. Pursuit of profit is to the public practice according to the logic of capitalist markets and customers seeking to protect the lives and property. However, the legal and institutional constraints of private security is being requirements inhibited by the development. Crime prevention as a private security role that the private companies, which will pursue the public interest. After all, the expansion of the private security crime is results in an increase in unit. The current level of private security in the 1970s remain, and the constraints is being under goodwill and expertise outside of the training system on the market. Variety of crimes, including cyber crime increases and considering the reality of the constraints on private security requirements are able to improve or supplement shall be realistic. In particular, the legal, regulatory and institutional factors must be improved, with goodwill, and for the creation of new industrial policy as a complement to the public interest should be also provided. The private security law interests through integration of private security guards should be guaranteed, and the term of the theorem, sales activities, ensuring the training of professional staff with professional qualifications system is to be settled. As a private security guard industry growth and development can be based on this composition.

After liberation, several literary groups with the nature of the national culture movement joined in Japan in January 1948 to form the Korean-Japanese Joseon Literary Society. However, the Korean-Japanese Joseon Literary Society was unable to play an active role due to the suppression of the GHQ and gathered again as the Korean War Armistice Agreement was concluded in 1953. The institutional journal of the 'Korean-Japanese Joseon Literary Society' is published by changing the magazine name to "Munhakbo" in Japanese and "Joseon Literature", "Joseon Literature and Arts" in Korean. The national movement group of Korean residents in Japan and literature groups were reorganized in conjunction with the political situation in Japan and the Korean peninsula. The reunion of 'Korean-Japanese Joseon Literary Society' was also based on the appearance of 'Jochongnyeon (pro-Pyeongyang federation of Korean residents in Japan)' and 'conversion of line'. In this paper, we are to fill up the blank of the research on literature of Korean residents in Japan in the 1950s by identifying the reality of conflict between 'Jochongnyeon' and 'Mindan', meaning of 'Korean Writing' Movement as a subject of national movement and the issue of promoting self-esteem as a 'citizen of the Republic' that 'Korean-Japanese Joseon Literary Society' tried to convey to Korean readers in Japan.

Recently, the Kim Jong Eun regime announced the completion of nuclear armed forces, and has been holding a summit meeting between the ROK and the US administration to promote the denuclearization of the Korean peninsula by the complete dismissal of the North Korean nuclear weapons toward the international community and the Republic of Korea. North Korea's Kim Jong Eun declares complete denuclearization, but in order to complete the real denuclearization of the Korean peninsula we seek, we need more practical preparation and preparation. In modern international society, the jungle law logic is applied precisely. A country that is not prepared cannot exist in history unless it believes only the good will of the other party and makes substantial preparations. Therefore, the top priority for us to prepare at this point is to obtain and manage complete information on the reality of North Korea's weapons of mass destruction. In particular, the weapons of mass destruction possessed by North Korea must be identified early on, and preparations for such weapons are essential, due to the seriousness of the damage. Therefore, this study complements the inherent limitations of modernized technology information in order to obtain accurate information on North Korea's threat of weapons of mass destruction, which is a serious issue directly linked to the survival of the Korean people and the state, And the operation plan was specified.

In this paper, we propose an evaluation model to evaluate the usability of locomotion technologies in a virtual environment (VE; Virtual Environment) and try to verify them through a case study. The order of this study firstly, the factors for analysis are derived through theoretical approach to locomotion technology on VR. Second, the definition and concept of mobile technology and usability evaluation in VR are established theoretically and the elements for analysis are derived through the literature survey through the theoretical approach to VE. Third, based on this, a usability evaluation model is proposed to evaluate locomotion technologies in the VE. Finally, the results are derived by experimenting and analyzing the existing VR games applied with the three locomotion technologies derived from the literature survey. Through this paper, the locomotion technology in VR is not used separately, but can propose mobile technology that conforms to VR game content characteristics by assessing its usability and analyzing it, and it is considered to be a significant data that can suggest criteria for identifying problems in locomotion technology.

The The government has recently announced its mid- to long-term plans for promoting art. With the advent of the 4th industrial revolution, contemporary art contents that are integrated with Intelligent Information Technologies such as Artificial Intelligence (AI), Virtual Reality (VR), and Big Data are being introduced, and social interest in humanities and creative convergence is rising. In addition, the industrialization of the art market is expanding amid the rising popularity of art among the general public and the growing interest of art as an investment replacement system, along with the strengthening of the creative personality education of our Education Ministry. Therefore, it is necessary to establish a strategy for transparency and revitalization of the art market by providing comprehensive information such as search functions, analysis data, and criticism by writer and price. This paper has established an information system plan for the establishment of an online supply system for art transaction information, providing auction transaction information for art market, providing report and news for art market, providing public relations platform, and providing art market analysis service and membership relationship management service. To this end, the future model was established through environmental analysis and focus analysis of the art market, and strategic tasks and implementation plans were established accordingly.

Recently, natural and social disasters in Korea are increasing, and new disasters such as COVID 19 and sinkholes, and large-scale disasters that combine natural and social disasters are occurring frequently. In order to reduce damage caused by disasters and effectively respond to disasters, the importance of disaster safety education is emerging because it is necessary to understand the awareness of disaster situations and the functional response process. Ministry of Public Interior and Security is providing disaster safety education for emergency managers through 54 specialized disaster safety education institutions. There is also a lack of experience facilities. This has a problem in that it makes it difficult for disaster safety personnel to effectively respond to disasters due to lack of experience in actual disaster sites. Also, unlike other education fields, the connection between disaster safety education contents and new technologies such as AI is still lacking. In this study, focusing on natural disaster, the current status and problems of domestic disaster safety education institutions and their contents are investigated and analyzed, and based on this, this study suggested improvement plans for domestic disaster safety education contents such as establishment of a unified disaster safety standard curriculum, production and distribution of disaster safety education experience contents using virtual reality technology and infotainment technology, and development of mobile AI tutoring service.

Recently, the metaverse has been receiving a lot of attention. Metaverse means a virtual space, and various events can be held in this space. In particular, 360-degree video, a format optimized for the metaverse space, is attracting attention. A 360-degree video image is created by stitching images taken with multiple cameras or lenses in all 360-degree directions. When shooting a 360-degree video, a variety of shooting equipment, including a shooting staff to take a picture of a subject in front of the camera, is displayed on the video. Therefore, when shooting a 360-degree video, you have to hide everything except the subject around the camera. There are several problems with this shooting method. Among them, lighting is the biggest problem. This is because it is very difficult to install a fixture that focuses on the subject from behind the camera as in conventional image shooting. This study is an experimental study to find the optimal angle for 360-degree images by adjusting the angle of indoor lighting. We propose a method to record 360-degree video without installing additional lighting. Based on the results of this study, it is expected that experiments will be conducted through more various shooting angles in the future, and furthermore, it is expected that it will be helpful when using 360-degree images in the metaverse space.

It is not easy to predict the future society in the rapidly changing present, but it is said that a new social environment of sensibility and virtuality will come, and we should pay attention to the fact that women have entered this as the subject. This study is a literature review study on gender roles. Through the study, it was found that gender stereotypes that exist in our society allow men to enjoy a lot of vested rights just by being male, and that women have to endure pain because they are women is accepted as a matter of course. Living in the 21st century, we were able to know the reality that we could not escape the pre-modern patriarchal ideology and still worshiped the idea of preferring boys. Through this study, unlike other elderly groups, elderly people who live alone are likely to be cut off from society and lead a limited life in their own world. However, through the efforts of the government, local organizations, and individuals, the goal of welfare for the elderly is to increase the satisfaction of life for the elderly living alone so that they can enjoy a successful old age. From this point of view, the support measures for the elderly living alone will be effective only when systematic and complementary in various dimensions such as family structure, physical, economic, and social aspects.

Recent advances in new media for sensory experiences keep expanding visual expression methods in installation art such as projection mapping and virtual reality. Artists can create and develop visual expression techniques based on such new media. Projection mapping is a new medium that continues to add various possibilities to visual expression in media art. Under the projection mapping environment, artists can recompose the object or space with the digital content by projecting video onto three-dimensional surfaces in the space. This paper focuses on the process where visual expression with the projection mapping technology leads to viewers' sensory experience. To this end, "reproducibility," "dissemination," "virtuality," and "interactivity" of media were analyzed to describe the meaning and *definition of visual expression. Artworks are considered as an example to study visual expression techniques such as "repetition and overlap," "simulacrum and metaphor," and "displacement and conversion." I applied the analysis and created Domino, a projection mapping artwork, which helps the research on visual expression techniques that can lead to sensory experience the extensibility of visual expression.
