방송용 문자발생 장비는TV방송의 역사와 함께 많은 변화를 겪어 왔다. 70년대 스캐너를 거친 문자를 방송에 이용하던 시절에 이어, 한국방송(KBS)에서는 자체 기술연구소에서 초기의 'DATAVIX'와 'Vidi-master'를 거쳐 '프리즘'시리즈 등을 연이어 개발하여 방송에 활용하였고, 디지털 방송시대를 맞아 근래에는 디지털 문자발생기 '다빈치'와 '다빈치젬' (daVinci GEM)을 개발하였다. 여기에서는 가장 최근에 개발하여 현업 활용을 앞두고 있는 '다빈치젬' 에 대해 소프트웨어 구조를 소개한다.

The purpose of this study is to compare the potential effects of service quality measured in DA VINCI and STARBUCKS, which were local and overseas reputable takeout coffee shop brands respectively, upon customer satisfaction, revisit intention and word-of-mouth(WOM). In order to achieve the goal, a survey was conducted to total 230 customers who have ever visited and experienced coffee shops in Daegu metropolitan city, and valid and complete 217 copies of the questionnaire were used for the final data analysis. As a result, the determinant of customer satisfaction was coffee quality for STARBUCKS(n=94) while it included coffee quality, reliability and service attitude for DAVINCI(n=123). Respondents regarded coffee quality as the most important for revisit intention both in STARBUCKS and DAVINCI. Also, the determinants of WOM included coffee quality and reliability for STARBUCKS, and coffee quality and service attitude for DAVINCI. In addition, it was found that the path coefficient of service quality influencing both customer satisfaction and WOM proved to show partially significant difference between STARBUCKS and DAVINCI.

영상 통화 시스템을 설치한 장소에서 대두되는 문제점은 문서 유출 등의 보안문제와 사생활 침해가 발생하는 것이다. 본 논문에서는 실시간 영상 통화를 하면서 문서유출 및 보안사항에 위배되거나 사생활이 침해되는 영상이 발견된 즉시 영상 통화를 중단시켜 보안유지 및 사생활 보호를 위한 다빈치 기반 실시간 영상 통화 시스템을 개발하고자한다. 구현 된 시스템은 실시간 처리가 가능하고 영상통화 시 문서 유출 등 보안문제가 발생하는 영상을 검출하는 알고리즘을 개발하여 다빈치보드에 포팅하고 여러 가지 보안사항에 대한 실험에 적용하였다.

Video-assisted thoracoscopic surgery has gained a broad acceptance for various thoracic lesions because it is the minimally invasive surgery with little tissue trauma, less pain, improved cosmetic results and short recovery time. However, there are some limitations for this method, such as restricted visual sensory information to a two-dimensional image and limited maneuverability of the tips of the instruments. To overcome these limitations, advanced technology has been introduced and the da $Vinci^{TM}$ Surgical System (Intuitive Surgical Inc, Mountain View, CA, USA) became available in 2001. In Korea, the da $Vinci^{TM}$ Surgical System was introduced in Severance hospital (Yonsei University College of Medicine) in May 2005, and approved by KFDA in July 2005. Herein, we report the first experience of robot-assisted thoracic surgery with the da $Vinci^{TM}$ Surgical System in extirpation of a large teratoma in anterior mediastinum.

In this paper, a new viewpoint and practical education method were presented on educational culture related to today's religions and media. For this purpose, this paper considered the theories of religious media pedagogic and the concept of symbo1ic didactics relating to religious symbols in popular culture. In this paper, a total of eight cases of applying symbolic didactics were developed using the example of "The Da Vinci Code", based on the theoretical framework of religious media education and symbolic didactics. For this, the education methods and contents of religious media education were integrated with the teaching plan model of "action and development oriented media education". In order for this education to be applied effectively, experimental studies have to be carried out verifying the learning effects regarding this education. In particular, education for teachers who will tarry out this education is needed. This is because, in media education, the efficiency of education is significantly affected by the capacity of the one who is teaching.

Background: The interest in robotic cardiac surgery has recently grown but there has not been much clinical research reported on this. The aim of this study is to examine our initial experience, since August 2007, with robotic cardiac surgery using the da $Vince^{TM}$ surgical system and to evaluate the feasibility and safety of it. Material and Method: Between August and December 2007, a total of 20 patients underwent robotic cardiac surgery using the da Vinci surgical system. For mitral valve repair (n=11), tricuspid valve repair (n=1), and ASD repair (n=1), cannulation, antegrade cardioplegia and transthoracic aortic cross-clamping were conducted for the right femoral vessels and the right internal jugular vein. For minimally invasive direct CABG (MIDCAB) (n=7), the internal thoracic artery (ITA) was harvested with the da Vinci surgical system. Result: The mean age of the patients was 50.1 (range: $26{\sim}78$) years. Three concomitant Maze procedures and one tricuspid annuloplasty were combined with mitral valve repair. The mean cardiopulmonary bypass time was $208.0{\pm}61.3$ minutes and the aortic cross clamp time was $158.8{\pm}40.6$ minutes. No patients showed more than mild mitral regurgitation after repair and the median hospital stay was 4 days. The robotic-harvested ITA was used for either left ITA (n=6) or bilateral ITA (n=1). The mean harvest time was $43.2{\pm}12.0$ minutes. The harvested ITA showed good flow and it was anastomosed under direct vision after left anterolateral thoracotomy. The patency of all the grafts was 100% (18/18) in MIDCAB. Conclusion: Robotic cardiac surgery using the da Vinci surgical system was variously adapted to areas such as mitral and tricuspid valve repair, ASD repair and ITA harvest for MIDCAB. The early results of the robotic cardiac surgery showed its safety and feasibility. With this primary report, we anticipate that clinical applications and further studies on robotic cardiac surgery using the da Vinci surgical system will be actively conducted in Korea.
