In this paper an analysis of current video chatting situation and connection status is performed and a technical method to block the obscene contents is proposed. Methods to shut down socially degenerate Internet sites are well known, which are essentially directory or vocabulary based. For the video chatting sites. however, dynamic selectivity is required as the chatting groups in a sites are all different and even in a single group the contents of chatting may turn socially objectionable as time passes. The proposed method is based on the analysis of chatting contents and selectively blocks the sound and/or video data streams. To prove the effectiveness of the method the experiments are performed and the results are shown very satisfactioy.

The purpose of this study was to examine the awareness and experience of extramarital relations across individual and familial variables of married men and women. Data for this study were 600 married men and women who were recruited the respondents through internet site. Results of this study were as follows; 1) Most of married men and women were regarded extramarital relations types(emotional connections, short-term relationship such as prostitution, sexual intercourse except a prostitution, one-night stands, physical connections, letter chatting with multimedia, video chatting with multimedia), By gender men had more permissiveness attitudes about extramarital relations type than women, 2) There were significant differences in the awareness and experience of extramarital relations types across variables(sex, age, education level, income, occupation, religion, marriage duration). 3) Married men reported that they experience(emotional connections, sexual intercourse, physical connections, letter chatting with multimedia, video chatting with multimedia, infidelity ideation, infidelity attempts) more extramarrital relations types than married women. There were significant differences in the experience extramarital relations types across variables.

We propose a video chatting algorithm using MPEG-4 over Mobile IPv6. This real-time system transmits video and character data based on UDP. To send data efficiently within limited bandwidth, we use a standard multimedia compression algorithm, MPEG-4, that encodes video data and mobile IPv6 guarantees effective mobility. This system presents the example of the mobile multimedia applications that will be the solution for the next internet services.

본 논문에서는 현대사회에서 응용분야가 광범위하고, 높은 인식율과 빠른 처리속도를 위하여 많은 연구가 진행되어왔던 오프라인 필기체 인식 중 디지털 펜을 위한 새로운 필기체 문자 인식 시스템과 이를 이용한 화상 채팅 시스템을 제안한다. 이 시스템의 문자 인식에 필요한 처리는 체인코드에 기반하며 유니코드와 획 코드를 이용하여 처리하는 필기체 문자 인식 시스템으로, 일반적으로 터치 패널이 없는 데스크 탑 과 노트북에서도 터치 펜 기능을 가능하게 하는 디지털 펜을 위한 필기체 문자 인식 시스템이며 화상 채팅은 WSAEventSelect Model을 사용하여 제작한 시스템이다.

After COVID-19, various metaverse platforms for online lectures are being provided. Most of the classrooms are tiered type, and they are divided into intensive classrooms and open classrooms depending on the shape of the classrooms. Intensive classrooms provide a one-sided lecture format, so there are many difficulties in conducting communication-based classes that carry out team missions like PBL classes. In this study, we propose a metaverse classroom that applies the functions of a multiplayer online role-playing game (MMORPG), one of the game genres suitable for PBL classes. The proposed system provides various interaction techniques for PBL classes. We evaluated user satisfaction when this was applied to actual classes. As a result of the evaluation, it was found that users preferred text and voice chatting more than video chatting and solving missions like games was very helpful in online classes.

SNS is a platformwhere users build a social relationship and share opinions and informations. To do these, it supports a text, an image and a video data. As it is possible to exploit the location data of a smart device, SNS tries to use the location data. However,since SNS does not support the coordinate data, it provides the restricted function sharing the image map instead of the vector map. In this paper, we propose a chatting systemsharing pathsto support the coordinate data on a classical SNS. On the proposed system, it is possible for usersjoined in a roomto watch a vector map of same area and exchange texts. If a user builds a path on the map, the system propagates the coordinate data of the generated path and the other users joined in the room watch the path immediately. The implemented chatting systemhasthe benefit to share the information related a map between users using coordinate data.

The purpose of this study is to provide basic data for the planning of adolescents preferred space, and fur the purpose of the study analyzed the spaces made by them in the web site where 3-dimension space manipulating is possible and captured their consciousness of space. The study was to interview 60 adolescents in the web-site by video chatting and observation by video ethnography. The results are as follows. 1) Three-dimension space is where adolescents express their present preference for spaces of residence, leisure and outer activities, and where they reveal their desire to be realized in the future. 2) Adolescents foster friendship in the cyberspace, where they meet friends and enjoy talking and share their desire for space creation which is hardly come true in reality. 3) It is possible to grasp their latent preference of space, and actualization of the cyber preference would give them more satisfaction.

The Web is a way to share documents and communicate. However, voice and video data can be transmission in real time and currently being developed by the objects and the objects that interact to further develop the Internet. Existing video and audio programs to transmission data to the interface of different types of systems a lot of constraint condition on the cost of the interface, extensibility. In this paper, voice and audio transmission system a different operating system, improve the constraints of the ERP system compatibility and extensibility is a open source based system developed by the research. The program is different types of systems and interface, extensibility with program design and development methodologies, and open source-based system composed This system is good for cost saving and extensibility. Therefore, systems research and development, Extensibility and excellent on the interface, system design and development methodologies, such as real-time video conferencing, HMI, and take advantage of your video available from SNS.
