The purposes of this study was to examine the effects of demographics, environmental attitude, environmental behavior, exposure to environmental information, and motives of clothing disposition on clothing disposal behavior. Data were obtained from questionnaires filled out by 217 women in Taegu and were analyzed by utilizing factor analysis, correlation analysis, and stepwise regression analysis. The results indicated that clothing disposal behavior was influenced by predicted variables such as education, exposure to environmental information, environmental attitude, and environmental behavior. Among predicted variables, the environmental attitude was the most important variable affecting clothing disposal behaivor. However, the proportion of variation in clothing disposal behavior that was explained by predicted variables was relatively low.

For human-robot interaction, a robot should recognize the meaning of human behavior. In the case of static behavior such as face expression and sign language, the information contained in a single image is sufficient to deliver the meaning to the robot. In the case of dynamic behavior such as gestures, however, the information of sequential images is required. This paper proposes behavior classification by using fuzzy classifier to deliver the meaning of dynamic behavior to the robot. The proposed method extracts feature points from input images by a skeleton model, generates a vector space from a differential image of the extracted feature points, and uses this information as the learning data for fuzzy classifier. Finally, we show the effectiveness and the feasibility of the proposed method through experiments.

The effects of material monitoring and information sources of maternal knowledge on externalizing and internalizing behaviors of adolescents were examined with a sample of 323 ninth-grade middle school students(163 boys and 160 girls) and their mothers. Data were collected using questionnaires regarding maternal monitoring, information sources of maternal knowledge, and externalizing and internalizing behaviors of adolescents. The major findings were that 1) unemployed mothers showed more monitoring than employed mothers; 2) mothers perceived that girls showed more self-disclosure and were more controlled by them than boys; 3) girls showed more internalizing behavior than boys; 4) the more adolescents were monitored by their mothers, the less internalizing behavior they showed; 5) the more maternal solicitation was used, the more externalizing behavior girls showed; 6) adolescents showed the least externalizing behavior when maternal monitoring was highly perceived by both mothers and adolescents. And perception of maternal monitoring by adolescents themselves plays an important role in showing less externalizing behavior.

Relaxing an unrealistic assumption of a representative percolation model, this paper demonstrates that herd behavior leads to a high increase in volatility but not trading volume, in contrast with information flows that give rise to increases in both volatility and trading volume. Although detecting herd behavior has posed a great challenge due to its empirical difficulty, this paper proposes a new methodology for detecting trading days with herding. Furthermore, this paper suggests a herd-behavior-stochastic-volatility model, which accounts for herding in financial markets. Strong evidence in favor of the model specification over the standard stochastic volatility model is based on empirical application with high frequency data in the Korean equity market, strongly supporting the intuition that herd behavior causes excess volatility. In addition, this research indicates that strong persistence in volatility, which is a prevalent feature in financial markets, is likely attributed to herd behavior rather than news.

In order to further improve the accuracy and time efficiency of behavior recognition in intelligent monitoring scenarios, a human behavior recognition algorithm based on YOLO combined with LSTM and CNN is proposed. Using the real-time nature of YOLO target detection, firstly, the specific behavior in the surveillance video is detected in real time, and the depth feature extraction is performed after obtaining the target size, location and other information; Then, remove noise data from irrelevant areas in the image; Finally, combined with LSTM modeling and processing time series, the final behavior discrimination is made for the behavior action sequence in the surveillance video. Experiments in the MSR and KTH datasets show that the average recognition rate of each behavior reaches 98.42% and 96.6%, and the average recognition speed reaches 210ms and 220ms. The method in this paper has a good effect on the intelligence behavior recognition.

Social networking service(SNS) helps users manage, share and delivery a vast information as a communication tool. When users read crisis news in SNS, they communicate the information with others by considering not only their belief (i.e., cognitive risk perception) but also emotion (i.e., affective risk perception). However, few researches have been interested in the construct of communication behaviors of crisis in SNS. This study aimed to explore the role of risk perception (cognitive and affective risk perception) between crisis responsibility and communication behavior through dual processing theory. As a result of the empirical analysis, crisis responsibility had a positive effect on cognitive risk perception and affective risk perception. In addition, cognitive risk perception had no significant effect on communication behavior whereas affective risk perception had influence on communication behavior positively. Thus, our findings may predict that the affective risk perception through crisis responsibility is more potentially important to communication behavior such as sharing information rather than cognitive risk perception. The results give insightful ideas why marketer should reduce perceived emotion caused by risk to strengthen prospective SNS users understanding of communication behavior intention.

이 연구의 목적은 재일한인의 정보행태를 분석하여 재일한인사회의 정보환경을 개선하기 위한 방안을 도출하는데 있다. 이 연구에서는 동경지역에 거주하는 한인의 정보행태를 집중적으로 파악한 후, 이 연구에 앞서 수행하였던 오사카지역에 거주하는 한인의 정보행태와 비교하면서 인구학적 특성에 따른 차이를 분석하였다. 이 연구를 위해 동경지역에 거주하는 한인 349명을 대상으로 한 설문조사와 20명을 대상으로 한 심층면담을 실시하였다. 오사카지역의 경우, 418명을 대상으로 한 설문조사와 40명을 대상으로 한 심층면담을 실시한 바 있다. 이 연구에서는 구체적으로 (1)동경지역 한인의 일상적 고민의 유형과 실체 그리고 대처 행태, (2)일상적 고민의 해결을 위해 그들이 선호하는 정보원과 정보매체의 유형과 실체, (3) 정보추구행태에서 나타나는 특징과 그러한 행태에 영향을 미치는 요인 등에 대해 논의 하였다.

이 연구의 목적은 대학 신입생을 사례로 하여 집단적 관점에서 드러나는 성격적 특성과 정보행태 사이의 관계를 밝혀내는데 있다. 이처럼 '성격적 특성'과 '정보행태'는 이 연구를 구성하는 핵심 변인이다. 이 연구에서는 성격적 특성 중에서 감성도과 의존도에 주목하고 있으며, 정보행태와 관련하여서는 정보요구, 정보추구, 정보소스, 정보탐색에서 나타나는 행태적 특징에 주목하고 있다. 연구에 필요한 데이터는 P대학교 2009년도 신입생 162명을 대상으로 하여 설문조사를 통해 수집하였다. 수집한 데이터는 성격과 정보행태에서 나타나는 전반적인 특징을 살펴보기위해서 빈도분석을 하였으며, 이들 두 변인 사이의 관계를 검증하기 위해서 Chi-square 검증을 실시하였다. 검증결과, 성격적 특성과 정보행태 사이에는 부분적이지만 통계적으로 의미있는 관계가 존재하며, 감성보다 의존성이 정보행태에 보다 밀접한 관계를 갖는 것으로 드러났다. 한편, 연구의 결론에서는 후속연구를 위한 방법론적 검증과 제언을 포함하고 있다.
