본 논문에서는 실시간 대화 행위에서 대화 메시지 사이의 응답 관계를 시각적으로 표현하는 방법을 제안한다. 제안한 방법은 기존 텍스트 기반 대화 방식과 트리 기반 대화 방식을 결합한 형태로서 대화 메시지의 일반적인 응답 관계뿐만 아니라, 기존 트리 기반 인터페이스에서 지원이 어려운 최근 수신 대화 메시지의 응답 관계를 시각화함으로써 대화자의 상호작용을 용이하게 한다. 이러한 방법은 기존 텍스트 방식의 테이블 구조에 트리 구조를 결함하여 대화에서 응답 관계를 명확히 구분한다. 제안한 방법의 구현은 XML과 DOM을 이용하여 대화 메시지와 대화 시스템을 구현하였으며, 응용 분야는 협업, 원격 교육, 온라인 게임 등이다.

This paper investigated the influence of foreign words, otherwise known as loan words, on global communication abilities of university students from two non English-speaking countries: Korea and Japan. To survey the understanding and usage of foreign words which are from English language and used frequently in daily conversation, questionnaires were administered to Korean and Japanese university students majoring in engineering who shared similar linguistic backgrounds. The results were analyzed from global communication viewpoint. Based on the results, methods for improving global communication skills in engineering education were proposed.

The present research examined the contribution of sounds′ familiarity to auditory distance perception, while attempting to control the influences of unavoidable physical characteristics among sounds. Different vocal "styles" ("shouts", "whispers" and "a normal conversation") of man and woman were recorded digitally and presented from a stationary loudspeaker to blindfolded listeners in a semi anechoic chamber. Playback levels were adjusted to remove extraneous sound level cues. The results showed that the shouting voice was judged as appearing farthest, the whispering voice closest, and the conversational voice was intermediate. The findings suggested that the perception of auditory distance may be affected by past experience (or familiarity).

The smart card including memory and processor is able to simple process such as privilege unauthorized access and used to Authentication System for security. In this paper, we propose using the smart card in the key exchange phase when secure Internet phones conversation, so certainly guarantee to mutual authentication and secret communication.

In this paper, we proposed new maximum electric power tracking algorithm by composing Buck-boost chopper circuit to charge electric power from wind energy generator which is under low and high wind velocity. The break function is also proposed with the existed buck-boost chopper switch. We made a proto-type as a lab level to verify appropriateness of using proposed circuit.

CVE(Collaborative Virtual Environment) is the virtually shared area where people cannot come together physically, but wish to discuss, collaborate on, or even dispute certain matters. In CVEs, in habitants are usually represented by humanoid embodiments, generally referred to as avatars. But most current graphical CVE systems fail to reflect the natural relationship between the avatar's gesture and the conversation that is taking place. More than 65% of the information exchanged during a person to person conversation is carried on the nonverbal band. Therefore, it is expected to be beneficial to provide such communication channels in CVEs in some way. To address this issue, this study proposes a scheme to represent avatar's gestures that can support the CVE users' communication. In the first level, this study classifies the non-verbal communication forms that can be applicable to avatar gesture design. In the second level, this study categorizes the body language according to the types of interaction with verbal language. And in the third level, this study examines gestures with relevant verbal expressions according to the body parts-from head to feet. One bodily gesture can be analyzed in the description of gesture representation, the meaning of gesture and the possible expressions, which can be used in gestural situation.

Noise occurred when medical treatment in dental clinic will affect the patients. This study was measured the noise level and frequency in case of medical examination and also has evaluated the degree of indoor noise using the NR-curve, NRN and a distance to conversation between worker and patients using the PSIL. It shows that noise level was 69.3~81.5dB(A) and frequency was very high (more than 4K(Hz)) and analysis by NR-curve showed that it was exceed the noise permit level and distance to conversation was less than 1meter by PSIL. To remedy a fear of noise in patients and provide a conversational satisfaction, it's considered that choosing the low noise-vib. equipment, using the masking effect and set the room to explain. So It is possible to improve their competitiveness.

This study is about an interface design supporting collaborative learning activities in online environment in which people exchange their knowledge and give feedback on personal storytelling to each other. Interface design issues from the viewpoint of Computer Supported Collaborative Learning (CSCL) on digital media design are considered. Based on collaborative learning theories and analysis on the existing online collaborative sites about digital media, such as online forums for digital pictures and films, interface guidelines are suggested and the interface is designed. The interface design is evaluated through a pilot test. The interface for collaborative learning on personal storytelling is designed to support observation and to provide a scaffolding for valuable conversation. It is also designed to help intersubjectivity of online conversation and an easy access to media.

The role of archives and records centers is expanding, however many potential users are not aware of the importance of the records and archives. As a method to improve the archival information services to users, in this study, we developed chatbot that supports the interaction between the users and the archives and records centers. Thus we examined the specific development procedures and methods, analyzed user requests and questions of the archives and records center of Myongji university as a case, and conducted a logical structure design for chatbot development. After building the chatbot based on IBM Watson Conversation and Kakaotalk messenger, we were able to find how the chatbot interacted with the users through a pilot run. Based on the experience of developing information service chatbot, the implications related the introduction of the chatbot were suggested which include determination of the level of the chatbot, analysis of the user requests, selection of the tool for the chatbot, and syntax setting for the conversational interaction.
