In digital broadcasting, applications are computer programs executed by the set-top box(TV receiver) , and synchronized applications are those that perform tasks at the specified moments in the underlying video. This paper describes important concepts, standards, and skills needed to implement synchronized applications and explains how to integrate them to implement these applications. This Paper assumes the European data broadcasting standard, DVB-MHP. In DVB-MHP, scheduled stream events are recommended as a means of synchronizing applications with video streams. In this method, the application receives each stream event, and executes the action associated with the stream event at the time specified in the stream event. Commercially available stream generators, i.e., multiplexers, do not generate transport streams that support scheduled stream events. So we used a stream generator implemented in our lab. We implemented a synchronized application where the actions triggered by stream events are to display graphic images. We found that our synchronized application processes scheduled stream events successfully. In our experimentation, the stream events were synchronized with the video and the deviation from the intended time was within 240 ㎳, which is a tolerance for synchronization skew between graphic images and video.

인터넷이 대중화된 현대사회에서 프로그램이 좀더 나은 가용성을 띠기 위해선 웹 브라우저를 이용한 인터넷 프로그램이 당연시되어 가는 추세에 이르렀다. 이러한 시점에서 전문가시스템으로 개발되는 모든 시스템도 현 추세에 맞게 변화해가야 할 것으로 생각한다. 본 논문의 목적은 JESS를 이용 전문가 시스템을 제작하여 구축 된 웹서버와 데이터베이스와의 연동으로 보다 효과적인 방법으로 많은 대중에게 전문가시스템의 사용을 일반사용자들이 접할 수 있도록 하는 기회를 제공함으로서 전문가시스템의 현실화에 접근하는 것이다.

The values of material civilizations that dominated the last century have been replaced with invisible values such as knowledge, information, and culture. The central axis of the world economy is also rapidly shifting from a capital and labor-intensive industry to a knowledge-based industry of software and contents. From the perspective of the industrialization of culture as multinational corporations and dominance and subordination relationships between cultures thereof, and crisis of cultural identity, the issues of support and fostering a culture industry arise. These have become major issues of concern in deciding national policies. In response to this trend, new departments related to culture contents in various universities have been established for fostering manpower in the field and the government policy to foster related human resources. However, actual results have not been currently achieved, despite the increase in quantity. This is due to the fact that the walls between culture contents departments were too high and thus education and fostering excellent human resources have not been properly conducted. It is also due to the obscure direction of education and a deficiency in the system. To cope with these problems, a systematic manpower-fostering education program should be developed through enhancement of the understanding of culture contents via linking education programs with detailed major fields of study. Accordingly, this study aims to identify changes in the current culture contents industry at home and abroad according to digitalization for fostering manpower of culture contents required in a rapidly changing environment of the culture contents industry. Then, it will review what influence has been made on the education system through the identification of personnel types through work flow charts and contents delivery modes following integration, as well as a desirable method to construct culture contents. Therefore, this study is a preliminary study on the means of fostering core personnel in the culture contents industry through linkage with the education system.

To identify virtual reality (VR) interventions used for upper extremity rehabilitation in stroke patients. The Medline database was searched up to February 11, 2015. Randomized controlled and clinical trials that included a VR intervention for upper extremity rehabilitation in stroke patients were included. The Physiotherapy Evidence Database (PEDro) scale was used to assess the quality of the included studies. In total, 8 studies were included. PEDro scores varied from 5 to 8/10. All studies showed significant improvement in outcomes in favor of the VR group. This review suggests that VR applications used for upper extremity rehabilitation in stroke patients predominantly mediate learning through providing task-oriented and graduated learning with variable and unpredictable practice.

Avionics OFP runs on the mission computer and can be operated by interacting with several avionics equipments. In order to verify OFP SW, SIL having real avionics equipments or models is absolutely necessary. Therefore in many cases SIL is implemented concurrently with OFP developing, and only one SIL is provided to developers. So developers sometimes need an alternative to SIL for verifying requirements in the middle of development process. In this paper, we propose a single PC based STE SW that simulates interworking equipments and verifies OFP in a single PC environment without actual interworking equipments or SIL HW interfaces.
