선진국 스마트폰 시장이 포화상태에 도달함에 따라 주요 IT기업들의 차세대 IT 비즈니스 발굴이 큰 화두다. 차세대 IT 비즈니스의 주목할만한 후보군 중 하나는 가상현실(VR: Virtual Reality)이다. 최근 고해상도 디스플레이, 강력한 컴퓨팅 파워, 3D센싱 등의 기술이 비약적으로 발달하고 하드웨어 비용이 크게 하락함에 따라 드디어 일반 사용자들을 대상으로 유의미한 수준의 '몰입감'과 '상호작용'을 제공할 수 있는 환경이 조성됐다. 현재 삼성전자, 소니, 엡슨 등의 대기업들이 VR 헤드셋 개발에 뛰어들었으며 뷰직스(Vuzix), 아 베간트(Avegant), 버추익스(Virtuix), 시브라이트(Seebright) 등의 가상현실 벤처기업들이 크게 주목을 받으면서 해당 업체들에 투자하겠다는 문의가 쇄도하고 있는 실정이다. 향후 가상현실 시장은 기업들에게 엄청난 비즈니스 기회를 제공할 것으로 전망된다. 단지 VR 헤드셋이나 관련 기기의 매출보다는 가상공간에서 사용자들이 소비하는 시간과 비용이 중요하다. 기존 오프라인, 온라인의 비즈니스 모델과 수익 모델 대부분을 가상현실에서 구현할 수 있다. 사람들은 앞으로 현실환경의 모든 오브젝트와 연결돼 상호작용을 하고, 또한 가상환경의 모든 오브젝트와 연결돼 상호작용을 하게 될 것이다. 그것이 진정한 사물인터넷과 가상현실이다.

The purpose of this study is to explore the interaction of virtual reality consumption pattern under the background of virtual reality, and the influence of such interaction on consumers' purchase intention. In this paper, we selected three independent variables (including content interaction, function interaction and service interaction) and two mediating variables (including perceived quality and perceived value) to explore the relationship between them and consumers' purchase intention, used SPSS24.0 and AMOS24.0, made the analysis of reliability and validity, constructed the structural equation model, and tested the hypotheses. The findings show that: fourteen hypotheses are all true, and the perceived value of virtual reality has a positive influence on consumers' purchase intention. In addition, we find that the perceived value has a mediating effect in this study.

More realistic calculation models for evaluating man's annual intakes of radionuclides released from operating nuclear facilities were established. For the application of these models, the harvest years of food and feed crops consumed in the year of dose assessment and every year's average concentrations of a radionuclide in air and in water for the whole period of real operation had to be taken into account. KFOOD, an existing equilibrium food chain computer code for the Korean dose assessment, was modified according to the models. Sample runs of the modified code on the assumption of a constant release during 10 years' operation were made with three kinds of the input data files enabling the dose assessment in the improved method, the KFOOD method and another existing method, respectively, and the results were compared. Annual committed effective doses to Korean adult by intakes of Mn-54, Co-60, Sr-90, I-131 and Cs-137 calculated in the improved method were about 11, 2, 5, 60 and 3%, respectively, lower than the corresponding KFOOD dose. To the intakes of the radionuclides except Sr-90 evaluated in the improved method, foliar uptake contributed much more than root uptake did but, in the case of Sr-90, the result was opposite.

This study is to identify marketing methods that are different from the existing ones on the Metaverse platform, where new business models and industrial ecosystems are being formed. The purpose of this study is to identify how brand marketing methods are differentiated according to the type of metaverse and the characteristics of the main users who use metaverse. The research method was a case analysis method, and Roblox, which currently has the largest number of active users, was selected. We closely analyzed how Nike and Gucci brands market by reflecting the characteristics and consumption patterns of Alpha Generation and Generation Z, the main users of Roblox. The results of the analysis are as follows. First, it is approaching with enjoyable content, including games, rather than direct marketing. Second, the content provided contains the brand's story and philosophy. Third, it takes a method of linking virtual and reality. Lastly, through Metaverse, Brands are identifying the tastes of future potential customers and collecting data for customized services.

This study seeks to find a way to induce users to expand their direct participation in sports through the acceptance of digital technology. From July 1 to August 30, 2022, a survey was conducted targeting home training users who applied the Internet of Things (IoT). 129 people participated in the survey through non-face-to-face self-administration method. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and 3-step mediation regression analysis were conducted using IBM's SPSS 21.0 program. The results of the study are as follows. First, in the relationship between the home training PPM model and direct participation in sports, ease appeared to have a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. In the mooring factors, individual innovativeness showed a complete mediating effect. Second, in the relationship between home training PPM model and direct participation in sports, usefulness showed a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. Among the mooring factors, individual innovativeness showed a partial mediating effect. Through this research, it is expected that the sports industry will contribute to the expansion of consumption expenditure and economic growth through the expansion of digital technologies such as NFT, Metaverse, and virtual/augmented reality.

Most of the sounds used in animated films are artificially made. A large number of the sounds used are either actual sound recordings or diversely processed artificial sounds made with professional sound equipments such as synthesizers. One animation episode contains numerous amounts of sounds, resulting in significant sound production costs. These sounds have full potential to be reused in different films or animations, but in reality we fail to do so. This thesis discusses ways these sound sources can be acknowledged as added new values to the present market situation as a usable 'digital content'. The iTunes Music Store is an American Apple company product that is acknowledged as the most successful digital content distribution model at the time being. Its system's sound library has potential for application in the Korean sound industry. In result, this system allows the sound creator to connect directly to the online store and become the initiative content supplier. At the same time, the user can receive a needed content easily at a low price. The most important part in the construction of this system is the search engine, which allows users to search for data in short periods of time. The search engine will have to be made in a new manner that takes into consideration the characteristics of the Korean language. This thesis presents a device incorporating the Wiki System to allow users to search and build their own data bases to share with other users. Using this system as a base, the Korean animation sound library will provide development and growth in the sound source industry as a new digital sound content.
