지난해 말부터 중국수출에 어려움을 겪어왔던 국내 게임업체들이 중국시장을 향해 재도약에 나섰다. 네오위즈, 엔도어즈, 인디21, 미리내엔터테인먼트 등 국내 게임업체들은 지난달 21일부터 24일까지 3일 동안 열린 중국 게임전시회‘차이나조이(China Joy)’ 에 참가, 국산 온라인게임의 최대고객인 중국 게이머들의 유혹에 나섰다. 이와 함께 한국소프트웨어진흥원은 베이징과 상하이에서 수출 상담회를 개최해 중국의 많은 업체들로부터 상담요청 및 계약을 성사시켰다.

본 연구에서는 뇌의 반응과 말초신경계의 변화를 통하여 유머와 기쁨의 긍정적인 정서의 구분이 가능한가를 밝히고자 하였다. fMRI와 말초신경계 반응 측정 실험 각각을 수행하는 동안, 유머와 기쁨정서를 유발하는 동영상 자극(2분)이 제시되었고, 실험이 끝난 후 심리적인 평가도 함께 수행되었다. fURI 실험은 boxcar design으로 한 session 내에 두 block으로 구성되었다. 말초신경계 반응실험에서는 안정상태와 정서상태에서의 피부전기 반응을 측정하였다. fMRI 결과, 유머자극과 기쁨자극 제시 시 공통적으로 precentral Cortex, temporal Cortex, precuneus 가 활성화 되었고, 유머자극은 기쁨자극에 비하여 우측 middle temporal cortex, 우측 inferior frontal cortex, 좌측 middle frontal cortex 에서 큰 활성화를 보였다. 피부전기 반응(EDA) 분석 결과 두 정서 모두 안정상태에 비하여 유의하게 증가하였고, 유머자극은 기쁨자극에 비하여 피부전도수준(SCL)과 피부전도반응의 수(NSCR)에서 유의하게 증가하는 것으로 나타났다.

The recognition of human emotional state is one of the most important components for efficient human-human and human- computer interaction. In this paper, four emotions such as fear, disgust, joy, and neutral was a main problem of classifying emotion recognition and an approach of visual-stimuli for eliciting emotion based on physiological signals of skin conductance (SC), skin temperature (SKT), and blood volume pulse (BVP) was used to design the experiment. In order to reach the goal of solving this problem, half-against-half (HAH) multi-class support vector machine (SVM) with Gaussian radial basis function (RBF) kernel was proposed showing the effective techniques to improve the accuracy rate of emotion classification. The experimental results proved that the proposed was an efficient method for solving the emotion recognition problems with the accuracy rate of 90% of neutral, 86.67% of joy, 85% of disgust, and 80% of fear.

The purpose of this study was to examine the proximity of clothing to self and proximity of cosmetic to self by Degree of Cosmetics. The scales used in this study include the arranged on the basis of Sontag (1978) 's study for proximity of clothing to self, and the scale developed by the researcher for proximity of cosmetic to self. The subjects of this study were 885 adult women in Taegu. The data collected were analyzed by using MANOVA, ANOVA, and the Cronbach a was also applied. The results of this study were summarized as follows: 1. The persons with high degree of cosmetics showed high degrees of joy of change, self-value expression, novelty, self-consciousness and consciousness to others in the sub-factors of proximity of clothing to self, while there was not significant difference in physical satisfaction. 2. The persons with high degree of cosmetics showed high degrees of social confidence, skin care, joy of change, self-satisfaction, instrument of disguise in the sub-factors of proximity of cosmetic to self.

A driver's emotion is a very important factor of safe driving. This paper classified a driver's emotion into 3 major emotions, can be occur when driving a car: Surprise, Joy, Tired. And It evaluated the classifier using Hidden Markov Models, which have observation sequence as bio-signals. It used the 2-D emotional plane to classfiy a human's general emotion state. The 2-D emotional plane has 2 axes of pleasure-displeasure and arsual-relaxztion. The used bio-signals are Galvanic Skin Response(GSR) and Heart Rate Variability(HRV), which are easy to acquire and reliable. We classified several moving pictures into 3 major emotions to evaluate our HMM system. As a result of driving simulations for each emotional situations, we can get recognition rates of 67% for surprise, 58% for joy and 52% for tired.

This study was conducted in order to develop a Children's Playfulness Rating Scale(CPRS) and to analyze it in terms of item discrimination, validity, and reliability. The participants in this study consisted of 861 parents whose children were aged from three to six years old. The item discrimination, determined by comparing the highest and lowest group using ${\chi}^2$, Cramer's V, was found to be satisfactory. The reliability of factors, as measured by Cronbach's ${\alpha}$, ranged from .85 to .95. The results of factor analysis identified 4 factors and 35 items were then selected from the 45 items in the original scale. The four factors identified were as follows; (1) leading participation (2) cognitive flexibility (3) expression of joy (4) voluntary full immersion. Concurrent validity was also established by using correlations between the CPRS and CPS(Children's Playfulness Scale). In conclusion, these results demonstrated that the Children's Playfulness Rating Scale is both reliable and valid.
