In this paper, we design and implement a SNS-web platform based video seminar system which supports effective information sharing and cooperation. The proposed system has 3 characteristics. First, a user can take part in Web-based video seminar without installing a specific hardware or software because our system has been developed with Java Web Start. Secondly, our system can be executed on various operating systems and internet web browsers. Thirdly, our system can support the expert knowledge sharing and cooperation among experts who are connected on SNS because the system operate on SNS-web platform. Finally, we show from our performance analysis that our system is efficient in terms of average delay time.

It is important to consider not only audio/video but presentation way, in video conferencing, seminar, lecture based network communication. The method to transmit image of a chalkboard used in traditional seminar, conference, lecture are one of difficulties for remote environment since it requires techniques high-resolution transmission and talking films. In this paper we implemented real-time multimedia shared board system for shared effective multimedia presentation using connection-oriented socket of TCP. In this system, decreasing cost of related system construction, improve of data reliableness and interaction, presentation delay time be able to minimize.

The purpose of this study was to develope Premarial Sexual Education Program. This program was based on survey(466 data used) for the need of PSEP. The result were as followings: 1. The need of sex education was higher(92.9%) and the participation of this PSEP was 80.4%, so this program was systemic structure. 2. Their premarital sexual values were more permissive(52.2%) than the past. But women thought tha female would be vergin(27.1%) their inter course experience rate was 33.4% and Age of experience was under 23 year olds. 3. The unmarried persns wanted that PSEP was consisted of 10 sub themes : (1) pregnancy and child-birth(mean=4.4/5) (2) contraception and family planning(m=4.3) (3) sexual morality and sexual value(m=4.2) (4) sexual healthy family (m=4.1) (5) sexual open communication(m=4.1) (6) venereal disease and coping stratiges(m=4.0) (7) sex role learning(m=3.9) (8) sexual physiology(m=3.8) (9) premarital sex and unwed mother(m=3.7) (10) adultery and society(m=3.6) 4. They want that group meeting would be every Wensday or Friday evening and the required time is two hours. The instruction methods are expected lecture, discussion or seminar and viewing video tapes. 5. So PSEP was consist of 10 sub-themes: (1) orientation and self-disclosure(test, lecture, game) (2) sexual physiology(video tape, lecture) (3) pregnancy and child birth(lecture, video tape) (4) contraceptive methods and family planning(lecture, video tape, test, discussion) (5) sex role learning(test, lecture, role-play) (6) venereal disease and coping stratiges(lecture, video tape) (7) premarital sex and incest(cause study, lecture) (8) sex morality and sex value(seminars, lecture) (9) sexual open communication(seminars) (10) sexual healthy family(lecture, seminars)

컴퓨터와 인터넷의 급속한 보급으로 인해 원격교육(Distance Learning)에 대한 많은 연구가 진행되고 있다. 그러나, 지금까지 대부분의 원격교육 시스템은 웹 기반의(Web-Based) 비동기(asynchronous) 형태로써 피교육자가 이미 제작된 컨텐츠를 다운로드하여 보는 단순한 형태의 교육방식이다. 따라서, 전통적인 면대면(Face-to-Face) 교육방식을 대체할수 있는 원격교육이 되기 위해서는 교육자와 피교육자, 피교육자와 피교육자간에 인지(awareness) 및 상호작용(interaction)이 가능한 원격교육의 기능이 지원되어야 한다. 본 논문에서는 비디오 및 오디오 컨퍼런싱(video and audio conferencing), 텍스트 기반 대화(text-based chat), 선 밀 텍스트 애노테이션이 가능한 슬라이드(slide with line and text annotation)를 제공하고 피교육자에 대한 인지정보(awareness information)를 공유하는 동기식 세미나용 원격교육 시스템을 설계하고 구현하였다.

In recent years, the use of touch screens has expanded, and devices such as remote controllers have been developed in various ways to control and access contents at long range. The wireless-based touch screen is used in classroom, seminar room, and remote video conversation in addition to the TV remote control. The purpose of the study is to design a smart phone-based intuitive interface that can perform the role of a wireless mouse and a wireless keyboard at range using Bluetooth and to develop an application that integrates functions of a mouse and a keyboard. Firstly, touch interaction model for controlling software such as PowerPoint by connecting to a general PC on a smart phone has been studied. The most simple touch operation interface is used to reproduce the function of existing devices and design more simply. The studies of the extension of interfaces with various functions are important, but development of optimized interfaces for users will become more important in the future. In this sense, this study is valuable.

최근 유무선 통신기술의 발달에 힘입어 정보소통의 주요 방식이 기존의 이메일에서 SNS로 변화되어 가고 있다. 이와함께 신속한 정보전달 및 원할한 협업이 기업의 경쟁력을 향상시키는 중요 요소로 인식됨에 따라, 영상회의 솔루션이 기업의 가치를 상승시키는 서비스로 주목받고 있다. 그러나 기존의 SNS의 경우, 일상적인 정보의 공유에 초점이 맞추어져 있어 전문지식의 공유 및 협업이 요구되는 전문가형 SNS로 활용하기에는 다소 미흡한점이 있다. 또한 영상회의의 경우, 특정 하드웨어 또는 소프트웨어를 설치하여야만 영상회의 솔루션을 활용할 수 있다는 문제점이 존재한다. 따라서 전문가를 위한 SNS개발을 위해서 본 연구에서는 SNS플랫폼 기반의 영상세미나 시스템을 설계한다. 설계하는 시스템은 Java Media Framework 및 소켓통신을 활용하여 영상세미나 시스템을 구축하고 아울러 Java Web Start의 형태로 SNS플랫폼 상에서 동작할 수 있도록 설계되었다. 이를통해 전문가를 위한 효율적인 정보공유 및 원할한 협업을 지원하며, SNS 플랫폼 기반으로 동작하기 때문에 기존 영상시스템을 활용하는데 발생하는 문제점을 해결할 수 있다.
