구름, 연기, 가스 등과 같은 반투과 매체 (participating media)를 사실적으로 가시화해주기 위해서는 그 내부에서 빛이 진행하는 과정을 물리적으로 시뮬레이션 해주어야 한다. 이 과정은 볼륨 렌더링 방정식이라는 적분 방정식을 통하여 표현할 수 있으나, 이를 정밀하게 푸는 것은 상당한 계산 시간을 요한다. 최근 GPU의 성능 향상에 힘입어, 반투과 매체에 대한 고속의 렌더링 기법들이 소개되고 있으나, 아직도 해결해야할 문제들이 많이 남아있다. 본 논문에서는 기존의 GPU 기반의 반투과 매체 렌더러의 기능/성능 향상을 위하여 적용한 렌더링 기법들을 설명하고, 그러한 노력들이 어떠한 개선 효과를 달성하였는지 분석한다. 이러한 기법들은 추후 각종 디지털콘텐츠 제작에 있어 특수 효과 생성을 위한 고속의 사실적인 볼륨 렌더러 구축에 유용하게 적용될 수 있을 것이다.

This study was conducted to investigate the motives and effects of artists and teachers who participated in the ' Explore Life through Art' support project for school education by theme of culture and arts. As a result of research analysis using online survey and in-depth interview research method, it was found that both intrinsic and extrinsic motives have a complex effect on artists and teachers' motivation to participate in the project. As for the effectiveness of participating in the project, the trust between artists and teachers and the contribution of education were positive, but the trust and satisfaction with the institution were negative. In order to increase the effectiveness of the project, it is required to improve the operation and management of the operating institution. Motivation and effectiveness of project participation are important factors in improving the quality of a project, and it is hoped that this study will serve as a basis for practical discussions on the role of operating institutions and projects.

This study examines the digital era's fashion system and defines fashion leaders in the system. The study was based on a theoretical review and a research survey to verify the theoretical findings. The results are follows. The critical changes in the fashion system are expansion, cyclical direction and closer distance between producer and consumer. By inflow of media to a new channel, a layer of consumers was extended and the range of celebrities participating in the fashion industry has expanded dramatically. Simultaneously with the change from vertical communication to cyclical and interactive, the direction of communication was re-routed through diverse media. Crowd sourcing activated through two-way communication service has increased consumer opportunities to participate in production and consumption. Fashion leaders have changed significantly under this new system. The range of celebrities participating in the fashion system has increased and different fashion leaders have appeared. An interactive and cyclical fashion system has been established through media innovation; consequently, the influential power of celebrities and individuals for direct participation in the fashion system directly has increased significantly.

This is the research on the correlation between the marketing activities conducted by the companies participating in the overseas exhibitions in the exhibition and the satisfaction of the visitors. I have been able to obtain the following findings through the positive research on the satisfaction of the visitors to the overseas exhibitions. The research findings show that the external elements of the participating companies such as 'external appearances of booths, interior facilities and the atmosphere', 'designs of exhibits', 'size of the participating companies', and the publicity elements of the participating companies such as 'the degree of application of mass media', 'prior publicity of the participating companies', etc. among the marketing activities conducted by the participating companies in the exhibition affect the interest and repeat business deals of the visitors. The findings also show that the elements to induce the interest of the visitors such as the booth design and display of products where the participating companies may produce their unique image and the prior publicity to the visitors constitute the important elements of marketing. It has also been revealed that the visitors whose purpose of the visits are to purchase the products and to satisfy their interest in 'the events and contents of the events affect the interest and the repeat business deals of the visitors, among the interest and repeat business deals pursuant to the characteristics of the visitors. It has also been found that the visitors who have recognized the representative brands in the exhibitions affect the interest and the repeat business deals and the visitors who have visited the exhibition several times are more satisfied than the visitors who have visited the exhibition for the first time. The comparative evaluation of the degree of importance of the marketing activities of the participating companies before the visitors' visit to the exhibitions and the degree of satisfaction after their visit reveals degrees of satisfaction in the order of 'the booth staff's professional knowledge of the exhibits', 'foreign language proficiency and their techniques of negotiation and demonstration', 'designs of the exhibits (colors and packaging), 'prior publicity of the participating companies. Such being the case, the companies participating in any of the overseas should maximize the result of their participation in the exhibition by training their staff in the products and foreign languages and through the prior publicity. It has also been found out that "the atmosphere of the booth in the exhibition such as 'launching of new products', 'external appearances of the booth, layout of the interior facilities and the atmosphere and events of the participating companies affect the interest and repeat business deals of the visitors, among the factors for the satisfaction of the visitors. Therefore, it has been proven that the external factors such as the external appearances of the booth, display of the products, launching of new products and events producing the atmosphere of the booth of the participating companies among the marketing activities conducted by the participating companies, and the extent of the training of the booth staff and prior publicity are the major factors affecting the interest and repeat business deals of the visitors.

본 연구에서는 한국 전통예술 중 하나인 진도 북춤을 다양한 인공지능 기술을 이용하여 디지털 아트로 재창조하는 과정을 제안하였다. 인공지능 언어 분석 기술을 통해 정량화된 관객들의 감정 데이터는 프로젝션 맵핑 공연에서 다양한 오브젝트 형태로 개입하여 큰 스토리에 변화를 주지 않는 선에서 영향을 준다. 대부분의 인터렉티브 아트들이 공연자와 영상 간의 소통을 표현한 것이라면, 본 공연은 인공지능 감정분석 기술을 중심으로 관객이 작품과 직접 소통할 수 있는 새로운 형태의 반응형 공연이 된다. 이는 한국 전통예술에서만 흔히 나타나는 관객이 공연에 직간접적으로 개입하여 영향을 끼치는 퍼포먼스인 '추임새'에서 시작된다. 공연자의 '프롤로그'에 담긴 감정 정보를 기반으로 관객의 감정 정보와 결합하여, 공연에 쓰이는 이미지와 파티클의 형태로 변환함으로서 공연에 관객이 간접적으로 참여하고 변화를 줄 수 있는 형태가 된다.

Natural convection and radiation heat transfer in a square enclosure containing absorbing, emitting, and isotopically scattering(participating) media is studied numerically using the finite volume method. Various numerical methods are employed to analyze the radiative heat transfer. However, it is very difficult to choose the proper method. In present study, a finite volume method(FVM) and a discrete ordinates method(DOM) are compared in rectangular enclosure. The SIMPLER algorithm is used to solve the momentum and energy equations. Thermal and flow characteristics are investigated according to the variation of radiation parameters such as optical thickness and scattering albedo. The result shows that the accuracy and the computing time of FVM are better than those of DOM in regular geometry.

Creative thinking appears even before it is expressed in language, and its existence is revealed through emotion, intuition, image and body feeling before logic or linguistics rules work. In this study, Lego is intended to present experimental child interactive content that is applied with a computer vision based on image processing techniques. In the case of infants, the main purpose of this content is the development of hand muscles and the ability to implement imagination. The purpose of the analysis algorithm of the OpenCV library and the image processing using the 'VVVV' that is implemented as a 'Node' in the midst of perceptual changes in image processing technology that are representative of object recognition, and the objective is to use a webcam to film, recognize, derive results that match the analysis and produce interactive content that is completed by the user participating. Research shows what Lego children have made, and children can create things themselves and develop creativity.

Purpose: To better understand the benefits and harms of engagement with online pediatric liver disease communities within social media. Methods: We conducted a survey of caregivers of children with liver disease participating in online pediatric liver disease communities within social media, as well as a survey of healthcare providers (e.g., physicians, surgeons, nurse coordinators) from this field to better understand the perceived benefits and harms of participation. Results: Among 138 caregivers of children with liver disease that completed the survey, 97.8% agreed social media was a good place to learn about patient experiences and 88% agreed it was a good source of general information. Among caregivers, 84.8% agreed social media helps them to better advocate for their child. While 18% agreed that the information over social media was equal to the information from their healthcare team and 19% neither agreed/disagreed, only 3% indicated they would use this information to change care without telling their provider; in contrast, among 217 healthcare providers, 55% believed social media may lead caregivers to change management without telling their team. Conclusion: Engagement with online disease-specific communities in social media yields several benefits for caregivers and, in contrast to healthcare providers' concerns, participation is unlikely to lead to problems including caregivers changing the treatment plan without first discussing these plans with their team. Openness between caregivers and medical teams about the role for social media can help to improve trust and maximize the potential benefits of engagement with these groups.
