SNS allowed users to serve not only as the content and message producer but as the consumer, with development into various types of SNS platforms. Instead of a traditional media structure of media-to-many and unspecified users, it also made it possible to achieve one-to-one or one-to-many interactions, regardless of time and space, through SNS platforms. Moreover, according to development of digital communication technology, IT, media contents and communication network have been mutually connected, though they were once separate. The changes in communication environments have caused rapid disorganization and reorganization in popular culture led by specific expert groups. Such trend has a greater influence on marketing strategies of enterprises. In other words, it will lead them to mostly introduce new information technologies, based on consumer market, and to strategically participate in SNS for promotion and marketing for their products and brands. Likewise, SNS has currently appeared as the main media affecting consumers' behaviors. In consideration of the importance of SNS features, which can stimulate responses of other users, analysis of main features affecting SNS user acceptance decision is required, as well as its utilization strategies. Accordingly, this study conducted division of SNS features into openness, quickness, interactiveness and economical efficiency to derive strategies for increasing the usage frequency of SNS and ultimately maximizing the expectation effect, in addition to an empirical analysis of effects of SNS features on usefulness, easiness and pleasure perceived in SNS, and SNS user intention.

An educational practice is a communicational course between educator and student with scheme and execution of studying. The communicational contents of the practical course require teaching transmission and recipient process for educator and student as a major knowledges end techniques in order to achieve student's aim. The communication of practical course consists of educators, students, and practical contents, and they also form both meaning objects and mutual relationships for constitution of the practical courses. In order to develop the effective plan for practical process, we have to understand the phenomena of meaning operations which consists in connections of the practical exercise and the meaning object. This study is to approach a phenomenal analysis as respects the meaning operations how forms of tie meaning object exert in the practical course. On the basis of this analysis, we grasp properties of the practical course into the meaning object, and in these connections, suggest the category of cognizance to put execution in the practical course by interpreting factors of the meaning operations.

With the development of information technology, users are provided with information they want through mobile device in various situations. When users communicate with information, there is interaction through gesture activities such as tapping and experience in the process. Experience through interaction in mobile affect the user's psychology. This is important because it is related to the behavior of the user in the future. Various types of information presentation methods have been researched in mobile environment. However, there are more research focusing on functional interactivity. The purpose of this study is to investigate the effect of interaction and usage mode on satisfaction, usefulness, and intention to use for sound text presentation that is user-centered. As variables for my study, there are two factors which are interactivity and usage mode. The interactivity type is composed of two ways that are: High and Low depending on modality and message interactivity; and the usage mode is composed of Action mode and Goal mode depending on whether user has a task or not. The experimental design is $2{\times}2$. The same content is provided in (a) only Modality interactivity, and (b) Modality and Message interactivity are provided. Depending on usage mode, (a) Action mode is processed without a specific task, and (b) Goal mode is performed with a specific task to participants. The experimental study demonstrated that there is a difference in satisfaction, usefulness, and intention to use depending on the difference of interaction and usage mode when providing information in mobile environment. The results of this study are summarized as follows: interaction and usage mode have significant influence on mobile user's satisfaction, usefulness, intention to use.

The communication environment made by digital technologies has made it possible to exchange information and deliver messages fast and easily among people of various classes in virtual space beyond time and space. Net-generation, who is accustomed to this virtual space, couldn't be satisfied with the linear text-oriented language any more, and began to make signs by use of computers in order to differentiate itself from others and to express its desires. Among the signs, emoticon created by joint of popular culture and digital communication centering around young generation is a new visual sign and emotional sign that can deliver a sender's feelings contained in a message. This paper has studied social phenomena, their relationships with emoticon and background of its creation through documentary review of media development, changes in the communication environment and popular culture. Furthermore, it has analyzed the meaningful action and roles of emoticon as a sign in terms of semiotics and also, studied a possibility of using emoticon as a new emotional sign. The study results say that emoticon can play the roles of a non-linguistic sign just like general signs that make mutual exchange through meaningful action, and also that it can be used to effectively deliver messages not only in virtual space, but also in advertising, posters, magazines and CI. However, emoticon is better at emotional expressions yet than other textual signs or visual signs, but in order to position itself as a universal and popular sign, emotional expressions should be clear, any difference in understanding messages should be removed, and message delivery should be more efficient.

The public trades information through social media during crises. The use of social media during crises has been increased steadily. However, there are few studies done on the effects of social media use on crisis perception. The goal of this study is to examine how social media affect an organization's ability to manage crises. The study specifically tries to investigate how media types, organization-public relationships, and image restoration strategies affect the public's perception of crises. An experiment was conducted to test research questions by presenting crisis scenarios and observing how newspapers and the social media Twitter affected the crisis. According to a three-way ANOVA test, the type of media and image restoration strategies had an interaction effect on the public's perception of crises. Also, the type of media, organization-public relationship, and image restoration strategies had a three way effect toward the acceptance of crisis communication strategies. As a result, it can be said that the public's perception and acceptances of crisis communication were different depending on the type of media used. The effectiveness of social media was proved, and it was seen that to be able to effectively use social media, each organization must have different strategies depending on their needs.

3 차원 그래픽스에 적용하는 한국어 립씽크 합성 체계를 연구하여, 말소리에 대응하는 자연스러운 립씽크를 자동적으로 생성하도록 하는 디자인 시스템을 연구 개발하였다. 페이셜애니메이션은 크게 나누어 감정 표현, 즉 표정의 애니메이션과 대화 시 입술 모양의 변화를 중심으로 하는 대화 애니메이션 부분으로 구분할 수 있다. 표정 애니메이션의 경우 약간의 문화적 차이를 제외한다면 거의 세계 공통의 보편적인 요소들로 이루어지는 반면 대화 애니메이션의 경우는 언어에 따른 차이를 고려해야 한다. 이와 같은 문제로 인해 영어권 및 일본어 권에서 제안되는 음성에 따른 립싱크 합성방법을 한국어에 그대로 적용하면 청각 정보와 시각 정보의 부조화로 인해 지각의 왜곡을 일으킬 수 있다. 본 연구에서는 이와 같은 문제점을 해결하기 위해 표기된 텍스트를 한국어 발음열로 변환, HMM 알고리듬을 이용한 입력 음성의 시분할, 한국어 음소에 따른 얼굴특징점의 3 차원 움직임을 정의하는 과정을 거쳐 텍스트와 음성를 통해 3 차원 대화 애니메이션을 생성하는 한국어 립싱크합성 시스템을 개발 실제 캐릭터 디자인과정에 적용하도록 하였다. 또한 본 연구는 즉시 적용이 가능한 3 차원 캐릭터 애니메이션뿐만 아니라 아바타를 활용한 동적 인터페이스의 요소기술로서 사용될 수 있는 선행연구이기도 하다. 즉 3 차원 그래픽스 기술을 활용하는 영상디자인 분야와 HCI 에 적용할 수 있는 양면적 특성을 지니고 있다. 휴먼 커뮤니케이션은 언어적 대화 커뮤니케이션과 시각적 표정 커뮤니케이션으로 이루어진다. 즉 페이셜애니메이션의 적용은 보다 인간적인 휴먼 커뮤니케이션의 양상을 지니고 있다. 결국 인간적인 상호작용성이 강조되고, 보다 편한 인간적 대화 방식의 휴먼 인터페이스로 그 미래적 양상이 변화할 것으로 예측되는 아바타를 활용한 인터페이스 디자인과 가상현실 분야에 보다 폭넓게 활용될 수 있다.
