To examine the role IM plays, We focus on the factors that promote or hinder communication within a Korean organization when instant messenger is used. These factors were examined through two research questions. To understand these issues, a survey consisting of 33 categories was given to government and corporate office workers in Seoul, Korea. The survey results showed that Instant Messenger is recognized as a powerful communication tool in official organizations, but is only used effectively within groups or generations that do not follow the hierarchical relationships characterized by Confucian values. The results of this study fill a gap in our understanding of the important role of IM use in organizational effectiveness and may prove useful when developing tools and strategies to help promote communication within organizations using information technology media.

In the current world, with the massive scale of SOC construction, it is difficult to diagnose and check all of a bridge's abnormal states with even the experts' eyes for maintenance. It is because we should spend huge costs and time on maintenance. Still, there are not many alternative ways to inspect bridges remotely regarding accuracy or reality. Therefore, we remark on the advantages and disadvantages of previous methods through practices in SOC maintenance. To inspect the abnormal state of the Bridge, we suggest inspecting bridges with an Augmented Reality (AR) mechanism to reduce cost, human resource consumption, and the risk of work. Through the proposed approach, we expect that it provides ways to solve massive construction problems with software-based technologies.

이 논문은 소설이 허구의 세계이지만 그 시대 사회상을 반영한다는 전제에서 조선시대의 인간 커뮤니케이션이 어떻게 이루어졌는지를 총 8편의 한글 소설을 통해 분석하였다. 분석 결과, 혈연간 구두 커뮤니케이션에서는 상하관계가 가장 중요한 변수였으며 비혈연 관계의 경우, 아는 사이에는 나이나 지위가 큰 차이가 없으면 상호 존중하는 어법을 사용하며 모르는 사이는 신분이 가장 큰 변수가 되었다. 관청과 민간에는 문서가 이용되기도 하였지만 문맹이 대부분이었기에 구두 커뮤니케이션도 사용되었다. 마을 공동체 내에서는 우물가나 빨래터, 주막 등을 통해 정보가 확산되면서 공동의 관심사에 대해 공론이 형성되어 갔다. 매체를 이용한 커뮤니케이션도 편지나 문서, 일기와 책 등의 형태가 이용되었다. 조선 시대에도 문서에 대한 신뢰는 매우 높았던 것으로 보인다. 이는 인쇄 시대 이전 구두의 증언이 문서보다 더 신뢰받던 서구와는 차별되는 측면이다. 남의 일기를 거리낌 없이 보는 것은 인쇄 문화의 특징인 프라이버시 관념이 아직 형성되지 않았음을 말해준다. 책은 수양과 여가 선용의 목적으로 의관을 정제하고 낭독하였다는 것이 특징이다.

It is necessary to understand a self-expression and communication in cyberspace using digital photography We have studied the digital camera consumer's self-expression and communication skills and strategy through ethnographic interviews. In this study, we have used ethnographic interviews of 7 informants who had personal web site and are using digital cameras. As a result, It has turned out that informants expressed their self taking pictures of their daily life, friends, and family. Also they imply meaning and feeling in the pictures that had been taken to express their lives. The communication in cyberspace has turned out that informants communicate with other people with digital pictures to show their life. They communicated each other and give information. It means that they made information by themselves to give and share with other people as prosumer. Digital photography to express themselves and communicate in cyberspace enhanced human relationship that had made in cyber space. And it helps to form their self identity. They express their cyber identity with digital photography and it is similar to their self identity that expresses in real life.

The education system is the communication field should be based on the characteristics of communication science and the function of manpower. However, the current education system at the level of college is insufficient and irrational to meet the requirements of the telecommunication field in our country. The main reasons are as follows: 1. Misunderstanding the characteristics of communication science. 2. Indiscretion of the categories of communication manpower due to lack of coordination between academic circles and communication industrial field. Telecommunication function could be performed only by combining the engineering and the suitable operational control. The communication engineering is similar to the electronic engineering, but the former should follow the miscellaneous international protocol and the domestic regulations, being only a means for the telecommunication function. In order to improve the education system of communiation, we aim to identify the principle of communication science, orthodoxy of the education, the categories of communication industrial field and manpower. The present system has been formed on the basis of ignoring the attributes of manpower and historical background of communication science. Therefore, this paper proposes to set up new departmental organizations for educating communication manpower as the following: In addition, this paper proposes a new curriculum model of the above twodept, and we believe that it well turn out more scientific, effective and reasonable education for the communication science. 1. Modification of the present formation, designated Electronic Communication Department. 2. New formation model: A. The best future model such as establishing ad independent telecommunication college which is composed of : Dept. of Radiocommunication Dept. of Telecommunication Enginnering Dept. of Communication Industrial management Dept. of Transmission Engineering Dept. of Telecommunication Law B. An immediately practicable proposal model instead of the existin Dept.. which is composed of the first two Dept. of the above five Dept. In addition, this paper proposes a new curriculum model of the above two dept. and we believe that it will turn out the education for the communication science to be more scientific, effective and reasonable.

Recently, new devices have been developed for the Internet of Things concept. The devices commonly use RF (Radio Frequency) based wireless communication. With the increase in the number of devices, the space allocated for the radio frequency band in wireless communication fills rapidly. Visible Light Communication (VLC) is an alternative, secure and economical communication technology that uses light instead of radio frequencies. While Web of Things (WoT) is the adaptation of the experience and knowledge acquired from the web into the internet of things ecosystems. By combining these two technologies, the development of the Visible Light Communication for Web of Things (VLC4WoT) system, which can use VLC and WoT technologies, has been our motivation. In our study, microcontroller control circuit was created for VLC4WoT system. Control of the circuits over the internet was performed. VLC based receiver and transmitter units have been developed for wireless communication. Web based interface was created for control. The test apparatus consisting of four objects with four outputs and a transfer unit was carried out. In this test, communication was achieved successfully. It was presented in the study that VLC can be used in the web of things architecture. In the future, it is envisaged to use this system as a safe and economical system in indoor environments.

Wireless Visible Light Communication is the technology that enables communication using LED illumination Infrastructure instead of existing illumination such as incandescent lamp or fluorescent light. Because VLC uses light for communication, it has no problem of frequency permission and is harmless to human body. It is also possible to check the communication through eye. So VLC can be used as a supplement to the Radio Frequency communication, Infrared in indoor environment. So far, researchers on the LED Visible light communication have focused on the increasing transmission speed, transmission distance, modulation method. However, there is few research of main factors that influence on system performance. System performance has been mainly predicted through simulation. In this paper, I recognized that these factors such as outside light noise, obstacle, LED panel position or emitted angle have a great impact on wireless communication system. So I experimented VLC system by changing distance and position to discover location suitable for BER regulation.

자동화 시스템은 RS232C에 의해 제어부와 GUI 시스템사이의 통신을 이용한다. 제업부는 실린더, 모터, 센서등과 같은 장치의 처리를 담당하며, GUI 시스템은 구동부로부터 직접 통신 방식이나 RS232C에 의해 신호를 받으며, 자동화 설비의 모든 상황의 분석 데이터를 사용자에게 제시한다. 이때 RS232C를 이용한 통신방식은 매우 중요하다. 이는 비용절감을 할 수 있으며 매우 단순한 구조를 가지므로 안정된 통신상태의 유지를 위한 유지보수가 쉽다. 반면 이러한 방법은 고속의 통신에서는 데이터나 신호의 손실을 가져올 수 있다. 따라서 데이터이 손실 없는 통신 프로세스의 제공은 매우 필요하다. 본 연구에서는 이를 위한 통신 알고리즘을 제시하였으며, 제어부와 자동화 시스템 사이의 RS232C를 이용한 송수신 상황에서 데이터의 손실을 막는 통신 처리를 구현하였다.
