The purpose of this study was to apply the Q methodology to type subjective perceptions of virtual clothing and to examine the characteristics of each type. Perceptions of virtual clothing were analyzed into four types. The first type was the "virtual clothing trusting fit grasping type," who preferred to use virtual clothing and believed that virtual clothing would help them grasp the fit. The second type was the shopping mall adoption-positive design understanding type, which believes that virtual clothing is useful for design understanding and that all shopping malls should have a virtual clothing system. The third type was the environmental pollution reduction virtual clothing purchase type, where the virtual clothing reduces environmental pollution and the user wants to purchase virtual clothing that cannot actually be worn. The fourth type was the actual clothing-like fun-seeking type, in which the virtual clothing resembles actual clothing and the shopper believes that the virtual clothing will make shopping more enjoyable. Depending on the type, the avatar was required to adjust the dimensions of the avatar, enhance the design expression of the garment, equip the avatar with decorative items, and produce virtual clothing for sale.

The purpose of this study is to understand the educational types and educational status of institutions that operate virtual training contents distributed by K University's Online Lifelong Education Center and to examine the role and improvement measures of institutions that supply virtual training contents. To this end, a survey was conducted on 56 institutions that operate virtual training contents distributed by K University's Online Lifelong Education Center in 2020, and a survey of 44 institutions that responded finally was analyzed. The analysis results are as follows. First, virtual training education media responded that a total of 52 courses were applied to the content process using PC, the theory+virtual training type is the most, and one to two weeks of practice period were the most. In addition, when looking at the current status of education, the subjects of virtual training were mainly students, and the institution itself recruited, and the largest number of respondents was 1-20, the number of courses opened was 1-3, and the number of teachers and instructors in charge was 1-3. Second, they responded that it is necessary to develop various virtual training contents as a virtual training content supply institution, present ways to apply and utilize virtual training curriculum, and improve the quality of virtual training content. Third, as an improvement plan for virtual training content distribution institutions, it demanded strengthening the linkage of virtual training content, training using virtual training content by teachers and instructors, suggesting various virtual training content linkage, and strengthening virtual training content quality management. Therefore, this study is meaningful in that it identified the overall operation status and status of virtual training content management institutions and examined ways to establish and improve the role of public virtual training supply institutions.

Virtual Advertising, which was introduced exclusively in sports casting programs in 2010, has enlarged its scope to terrestrial TV networks' sports news, entertainment shows, and dramas by 2015. Such advertising deregulation allows broadcasting business operators to insert more various virtual advertising methods into TV programs. Despite recent evaluation that virtual advertising was deregulated to a large degree, it is still inadequate compared to foreign state of affairs and has a lot of room for growth. Therefore, this research explores a literature review of virtual advertising in other countries and considers possible ways for virtual advertising in Korea to move forward. Additionally, through in-depth interview with seven virtual advertising experts, the research unravels positive and negative impacts of virtual advertising as well as its current state of affairs and struggles. This research also analyses the regulation of virtual advertising and finally explores possible revitalization strategies. The results of the research show that it is necessary to first improve the viewers' favorable concerning virtual advertising in order to revitalize virtual advertising. Revitalization will also require a clarification of regulation as well as a more unified and consistent content review and rating system. Furthermore, it is imperative that data of advertising impact will be accessible to advertisers and that advertising regulation will loosen. Revitalization will also require a clarification of regulation as well as a more unified and consistent content review and rating system. Furthermore, it is imperative that data of advertising impact will be accessible to advertisers and that advertising regulation will loosen. It is necessary to further develop new techniques and creators of virtual advertising. The research suggests strategies and alternative paths for the growth and revitalization of the virtual advertising market in light of recently revised law.

최근에 축구 중계 방송에서 경기장 바닥에 로고와 함께 득점 상황을 보여주거나 대형의 가상 전광판 같은 그래픽 영상을 경기장에 실레조 존재하는 듯이 합성하여 보여주는 것을 종종 볼수 있다. 이를 가능하게 하는 것이 가상이미징(virtual imaging) 기술이며, 외국에서는 가상광고(virtual advertising)로도 이용하고 있다 본고에서는 새로운 영상합성 기술로 각광받고 있는 가상이미징 시스템에 대하여 살펴 보고자 한다.

가상시험장은 양질의 시험 서비스를 보다 적은 비용으로 신속하게 제공하면서 실제 시험시에 발생할 수 있는 새로운 시험공간의 확보, 안전문제, 오염방지, 민원등에 효과적으로 대처할 수 있는 기술로 판단된다. 가상시험장의 효용가치는 가상시험 결과와 실제시험 결과의 근접성에 의해 결정되므로 모델링과 시뮬레이션 기술 개발과 더불어 Ground Truth Data의 축적이 선행되어야 성공적인 가상시험장 구축을 기대할 수 있다.

Virtualization obfuscation makes hard to analyze the code by applying virtualization to code section. Protected code by common used virtualization obfuscation technique has become known that it doesn't have restored point and also it is hard to analyze. However, it is abused to protect malware recently. So, It is been hard to analyze and take action for malware. Therefore, this paper's purpose is analyze and take action for protected malware by virtualization obfuscation technique through implement tool which can extract virtualization structure automatically and trace execution process. Hence, basic structure and operation process of virtualization obfuscation technique will be handled and analysis result of protected malware by virtualization obfuscation utilized Equation Reasoning System, one kind of program analysis. Also, we implement automatic analysis tool, extract virtualization structure from protected executable file by virtualization obfuscation technique and deduct program's execution sequence.

This paper presents the development of a certain highly efficient authoring tool for constructing realistic 3D virtual space using image-based rendering techniques based on a virtual space map. Unlike conventional techniques such as TIP, for constructing a small 3D virtual space using single image, the authoring tool developed herein produces a wide 3D virtual space using multiple images. This tool is designed for constructing each small 3D virtual space for each input image, and for interconnecting these 3D virtual spaces into a wide 3D virtual space using a virtual space map. The map consists of three elements such as specific room, link point and passageway, and three directions. It contains various information such as the connection structure, the navigation information and so on. Also, the tool contains a user interface that let users construct the wide 3D virtual space easily.
