최근에는 통신기술과 인터넷의 발달로 원격의 사람과 전화, 이메일, 메신저 또는 화상회의 시스템 등을 통해서 쉽게 의사소통 할 수 있다. 이 시스템들은 주로 음성, 그림, 동영상 또는 문자 기반의 시청각 정보를 서로 주고 받으며 자신의 의사 및 감정을 전달하는 통로를 제공한다. 그러나 일상 생활에서 시청각 정보 외에 촉감 정보도 서로 의사소통 하는데 중요한 역할을 한다. 악수, 포옹 등의 촉감 상호작용은 사람 사이에서 친근감을 표시하는데 가장 직접적인 방법으로 자신의 감정을 전달하거나 느낌을 표현하는데 사용된다. 그럼에도 불구하고 촉감 상호작용을 가능케 하는 의사소통 시스템의 연구는 아직 폭넓게 진행되고 있지 않다. 본 논문에서는 일상에서와 같이 원격에서도 상대를 바라 볼 수 있고 자연스럽게 접촉할 수 있는 원격 촉감 커뮤니케이션 시스템을 제안한다. 이 시스템에서는 로컬 사용자가 손가락으로 상대의 몸 특정 부위를 만질 수 있고 서로 그 촉감을 실시간으로 느낄 수 있다. 이 시스템은 크게 AR 시스템, 그래픽 시스템, 햅틱 시스템, 택타일 시스템의 부시스템들로 나눌 수 있다. AR 시스템에서는 몸의 한 부위에 사각형의 AR 마커를 부착한 원격 사용자를 웹카메라로 촬영하고 ARToolKit 을 사용하여 마커의 위치를 측정한다. AR 마커의 바로 밑에는 택타일 장치가 장착되어 있으며 이 부위를 통하여 원격의 사용자는 로컬사용자가 자신의 팔을 만지는 느낌을 받게된다. 그래픽 시스템은 로컬사용자에게 촬영된 원격 사용자와 측정된 마커의 위치가 대표하는 원격 사용자의 가상 피부, 그리고 자신의 가상 손가락을 보여준다. 햅틱 시스템에서는 촉감 장치를 사용하여 로컬 사용자의 손가락 위치를 구하여 원격 사용자의 가상 피부와 접촉했을 때 그 충돌을 감지하고 접촉력을 계산하여 촉감 장치에 반영함으로써 그 접촉력을 느낄 수 있도록 한다. 택타일 시스템에서는 원격 사용자의 AR 마커 밑에 장착된 배열 타입의 진동 촉감 장치에 접촉 정보를 주어 로컬 사용자와 접촉 했을 때 접촉 부위에 진동을 줌으로써 촉감을 느끼도록 한다.

In light of the recent advancement in networking and information technology, the direct information request through website has increasingly proven to be the preferred means over visiting physical archives. Thus, the proper utilization of a communication tool capable of sufficiently capturing user feedback and requests is an absolute necessity. This paper examines the availability and utilization of alternative user participatory communication tools in government websites with particular focus on the archives in South Korea, the United States, the United Kingdom, Canada, China, and Japan. In assessing the use of alternative user participatory communication tools in these archives, we examined the availability of communication mediums other than the online forums, email, and telephone with particular focus on social media tools that may offer a degree of familiarity for the user. Our research indicates that the most frequently utilized social media tool is Facebook while the archive offering the greatest variety of alternative user participatory communication tools was the United States archive.

Media art is developing the art of 'interaction' that get meaning through communicating an audience. Now, media art got the title named interactive media art, but its concept is not clear In this study we divided into two classes - passive and active interactive art. Passive interactive art had the interaction 'participation of communication' and had flat and limited features. Active interactive art meant that an audience played with works actively and found significances between artworks and themselves. Through analysis of case study, we verified a propriety about own interactive art's division. Especially, the active interactive art was very important. The western classical metaphysics seemed to be not perfect in analysis of active interactive art. We tried to analyze active interactive art more perfectly by using the oriental philosophy.

During COVID-19, education industry is organizing the concept of 'Edutech', which has evolved one step further from the existing e-Learning, by introducing various intelligent information technologues based on the core technology of the 4th industrial revolution and spreading it through diverse contents. Meanwhile, each industries are creating new industries by applying new technology to existing businesses and ask for needs of cultivating human resources who understand the existing traditional ICT technology and industrial business which can solve a newly rising problems. However, it is difficult to build contents for cultivating such human resources with the existing e-learning of transferring knowledge by one-way or some two-way commnication system which has established some interactive conversational system. Accordingly, this study conducted a research on a cooperative e-learning system that enables educators to communicate with learners in real time and allows problem-solving education based on the existing two-way communication system. As a result, frame for contents and prototype was developedp and artially applied to the actual class and conducted an efficiency analysis, which resulted in the validation of being applied to the actual class as a simulation-based cooperative content.

The variable message sign (VMS) is equipment to improve the efficiency of traffic flow and safety of travel by providing real-time information to road users on traffic, road, weather situation, and traffic control due to construction. The information messages of the letter-based VMS taking up most of the VMS on the general national highways consist of section, travel time in sections, and road control situation. This study devised an improvement plan centered on road users, not road managers-centered existing message-based VMS through an analysis of road users' preference targeting the letter-based VMS operated in the general national highways in the Seoul Metropolitan Area. By presenting the measure for system improvement through which information on unexpected situations that road users prefer the most can be quickly and efficiently provided, this study aims to improve the efficiency of road user-centered VMS traffic information.

Politics and conflicts within organizations are natural phenomena found in any type of organization, affecting organizational outcomes and output variables. Nevertheless, there are not many previous studies on politics and conflict within nursing organizations. Therefore, in this study, we would like to analyze how the internal politics and conflicts, which have been excluded from the previous studies related to nursing organizations, affect the quality of communication between nurses. Data were collected from 310 nurses in an university hospital. Using SPSS21, the data were analyzed by descriptive statistics, Pearson's correlation analysis, and multiple regression analyses. As results of the analyses, the organizational politics and relationship conflict have negative effect on the quality of vertical and horizontal communication, and task conflict has a positive effect on them. Organizational politics and relationship conflict have negative effects on quality of formal communication. Organizational politics and conflicts did not significantly affect the quality of informal communication. These results suggest that active, managerial efforts should be executed to overcome the negative effects of organizational politics and emotional conflicts among nurses. Furthermore, empirical research on organizational politics and conflicts within nurses organizations should be expanded.

From an accident at 2:00 a.m. in November 2nd, 2012 that one fire-fighter died while suppressing the E land World Inc. Fire in Bupyeong-Gu, Incheon, we concluded the problem and the improvement method of using the wireless communication (the two-way radio) that the fire safety officer and the safety crew use when identifying the safety of the fire scene. And after the investigation, we could find that the communication between the fire safety officer and the safety crew was difficult in the scene of the fire by voice because of much noise, so they could rely solely on the wireless communication. Therefore, we investigated the wireless communication and its frequency now used in Incheon Fire Safety Devision. Also, we compared with those of the military and the police. As a result, by making use of the wireless communication and its frequency currently possessed in Incheon Fire Safety Division, we found that the fire safety officer and the safety crew rescuing people at the risk of their own life in the various fire scene can communicate effectively.

Vision-based Human computer interaction is an emerging field of science and industry to provide natural way to communicate with human and computer. In that sense, inferring the emotional state of the person based on the facial expression recognition is an important issue. In this paper, we present a novel approach to recognize facial expression from a sequence of input images using emotional specific HMM (Hidden Markov Model) and facial motion tracking based on optical flow. Conventionally, in the HMM which consists of basic emotional states, it is considered natural that transitions between emotions are imposed to pass through neutral state. However, in this work we propose an enhanced transition framework model which consists of transitions between each emotional state without passing through neutral state in addition to a traditional transition model. For the localization of facial features from video sequence we exploit template matching and optical flow. The facial feature displacements traced by the optical flow are used for input parameters to HMM for facial expression recognition. From the experiment, we can prove that the proposed framework can effectively recognize the facial expression in real time.
