Positive affect has beneficial consequences in various life domains including social relational aspect. This study proposes that 'joy,' a highly arousing positive social emotion, promotes emotionally supportive reactions during a social interaction. In Study 1, after controlling for confounding personality characteristics (e.g., extraversion, agreeableness, adult attachment) and cognitive variables (e.g., empathy, self-esteem), positive affect predicted the amount of emotional support and enthusiasm one showed to a person who was describing a positive experience. The arousal dimension of positive emotion appeared to be the key in creating this outcome. Study 2 found that people were most likely to react in supportive ways (e.g., more laughing, emotion sharing, and active-constructive responses) to other's conversation after viewing a joy-inducing (rather than pride, awe, calm) film clip. These results partly explain why happy people are socially popular and suggest that one of the central functions of "joy" is to promote social bonding with others.

본 논문에서는 아라비안 숫자를 포함한 텍스트를 음성으로 합성하기 위하여, 숫자 형태와 분류사 그리고 숫자가 나오는 문맥에 따라 숫자를 자동으로 문자화할 수 있는 전처리 규칙을 설정하는데 목적을 둔다. 먼저 선행연구를 통해 숫자를 포함한 수사 및 수사표현의 읽기 규칙의 적용 범위 및 한계점을 살펴보고, 음성 합성을 위한 아라비안 숫자의 문자화 규칙을 설정하고자 한다. 현대 한국어에서 아라비안 숫자를 읽는 방식은 크게 고유어 방식과 한자어 방식이 있으며 단(單)단위에서는 영어가 사용되기도 한다. 또한 한자어 방식에서도 단위를 붙여 읽는 경우와 모든 수를 단 단위로 읽는 경우가 있으므로, 아라비안 숫자의 문자화를 단순한 규칙을 설정하여 자동화하기에는 중의성이 높다. 본 연구에서는 (1) 숫자 전 전치어(pre-numeral), (2) 기호를 포함한 숫자열의 표현 형식과 크기, (3) 단위 표현, (4) 숫자 후치어(post-numeral), (5) 분류사(classifier) (6) 분류사 후치어(post-classifier), (7) 수사표현 앞뒤 문맥에 따라, 아라비안 숫자표현이 문자화되는 방식을 살펴보았다. 분석 대상 말뭉치는 C 신문의 2000년 1월부터 2000년 4월까지 전체 기사 1,400건에서 숫자가 포함된 숫자표현 약 63,000개론 구성하였다. 패턴화된 구조 및 중의성이 없는 구조를 12가지로 밝히고 중의성이 있는 구조의 유형을 밝혔으며 분류사 후치어와의 결합 관계, 좌우 문맥정보를 통해 중의성 해결의 단서를 제시하고자 하였다.

Currently, finding one's way in the underground spaces associated with subway stations in large cities is becoming a serious problem, and an environment that facilitates wayfinding is becoming more important. This study investigated interior treatments that function as visual cues in the subway stations of Seoul, Tokyo, and Taipei in order to develop design guidelines that would improve the place-cognition environment. A theoretical study has shown that there are three categories of visual cue for place cognition: marked trails, regional differentiation, and landmarks. The case study showed that marked trails involve treatments like vertical markers, confrontational positioning, and subway color codes. Regional differentiation involves patterns on the floors and walls, and accent colors on the walls and columns. Landmarks include treatments such as super graphics, symbolic features, artistic decoration and special lights. In the cases of Seoul, marked trails and regional differentiation were predominant. In addition, the Olympic symbol 'Hodori' and the ancient Korean character "Hunminjungeum" were used as landmarks. In the cases of Tokyo, regional differentiation predominated over marked trails because of the complexity of the spatial structure and subway line connection system. In the cases of Taipei, simple, unified images predominated, and there was minimal dependence on marked trails and landmarks. The need for regional differentiation was weak, because the stations studied have open structures that guarantee an open field of view. The results of this research could be used as design guidelines, after further experimental verification, that would help to improve the public environment in terms of wayfinding.

The scale of visual expression has expanded from freeze frame to motion picture as media have developed. Moving pictures such as animation, movies, TV CM and GUI become formative elements whose movement is necessary compared to freeze frame as apparent movement phenomenon and unit structure such as short and scene appear. Therefore, of formative elements such as a shape, color, space, size and movement, movement is importantly distinguished in the moving image. The expression and form of image as a relationship between the signified and signifier explained by Saussure are accepted as a sign by mutual complement even though they limit the content. This makes it possible to infer that the formal feature of movement participates in the message content. To verify this, the result of moving picture visual perception experiment based on the gestalt grouping principle result shows that 70-80 percent of subjects think that 'movement' is the important grouping clue in perception. Movement affects the maintenance of the context of message content in the communication process when the meaning structure of moving picture is analyzed based on the structural feature. The identity can be maintained with if there is a movement with similar directive point even if the color and shape of people, things and background are changed. Second, the clarity of the content is elevated by a distinguished object as a figure by movement. Third, it acts as a knowledge representation which can predict similar movement process of next information processing. Forth, movement gives the content consistency even though more than two scenes have fast switch and complicated editing structure like cross-cutting. Movement becomes a clue which can make grouping information input by visual perception reaction. Also, it gives the order to the visual expression which can be used improperly by formation of structural frame of image message and has the effectiveness which elevates the clarity of signification. Moving picture has discourse with several mixed unit structures because it fundamentally contains time and the common and distinguished expression is needed by media-mix circumstances. Therefore, by the application of gestalt grouping principle to moving picture field, movement becomes the more distinguished than other formative elements and affects the formation of meaning structure. This study propose a viewpoint that develops structural formative beauty and new image expression in the media image field.

This study involves an experiment aimed to reveal the communicative effects by different types of visual expressions in SNS advertisements. This study analyzes consumers' dynamic responses to vicarious emotional experiences and the creative rhetorical expressions of networking media platforms through experiments that sample university students. The vicarious emotional experiences of networking media platforms have a significant effect on the consumers' subsequent reactions. The greater the vicarious emotional experiences are, the more positive this effect is. There is a significant interactive effect between consumers' vicarious emotional experiences and the rhetorical creative types of targeted media.

This paper proposes a method of automatically identifying sentence types in Korean and improving naturalness in sign language generation and speech synthesis using the identified sentence type information. In Korean, sentences are usually categorized into five types: declarative, imperative, propositive, interrogative, and exclamatory. However, it is also known that these types are quite ambiguous to identify in dialogues. In this paper, we present additional morphological and syntactic clues for the sentence type and propose a rule-based procedure for identifying the sentence type using these clues. The experimental results show that our method gives a reasonable performance. We also describe how the sentence type is used to generate non-manual signals in Korean-Korean sign language translation and appropriate intonation in Korean speech synthesis. Since the method of using sentence type information in speech synthesis and sign language generation is not much studied previously, it is anticipated that our method will contribute to research on generating more natural speech and sign language expressions.

The purpose of this paper is to represent values of acoustic cues for Korean oral stops in the multi-dimensional space, and to attempt to find possible relationships among acoustic cues through correlation analyses. The acoustic cues used for differentiation of 3 types of Korean stops are closure duration, voice onset time and fundamental frequency of a vowel after a stop. The values of these cues are plotted in the two and three dimensional space to see what the critical cues are for separation of different types of stops. Correlation coefficient analyses show that multi-variate approach to statistical analysis is legitimate, and that there are statistically significant relationships among acoustic cues but Oey are not strong enough to make the conjecture that there is a possible relationship among the articulatory or laryngeal mechanisms employed by the acoustic cues.

본 논문은 방송 및 통신 환경을 이용한 멀티채널 음향 재생 환경에서 다수 객체의 음상 정위를 보다 효과적이고 효율적으로 하기 위한 방법에 관한 것이다. 본 논문에서는 전송되는 정보의 양을 최소화 하면서도 재생되는 음향공간에서는 다수의 음향 객체들이 충실하게 재생되어 자연스러운 음향공간이 재현할 수 있는 방법을 제시하고가 한다. 기존 방법의 경우, 전송 선로를 통해 음원을 압축하여 전송하기 위해서는 먼저 멀티채널 신호를 합한 모노신호와 채널 신호사이의 음량차이(ICLD), 시간지연 차이(ICTD), 상관도(ICC)등을 전송하는 양귀단서 신호화 기술(Binaural Cue Coding)을 이용하고 있다. 본 논문에서는 멀티채널 음원을 분석하여, 음원의 가상 위치정보를 벡터적으로 표현하고, 이 위치벡터와 멀티채널 음원을 하나의 모노 음원으로 다운 믹스한 신호를 전송함으로써 전송 효율을 극대화 한 압축 재생 방법을 제시한다.

The acoustic cues used for differentiation of 3 types of Korean stops are closure duration, voice onset time and fundamental frequency of a vowel after a stop. The values of these cues are plotted in the two and three dimensional space and see what the critical cues are for complete separation of different types of stops. Correlation coefficient analyses show that there are statistically significant relationships among acoustic cues but they are not strong enough to make a conjecture that there is a possible articulatory relationship among the mechanisms employed by the acoustic cues.
