정서를 측정하고 나타내는 기술이 발전에 따라 문화적 보편성을 가진 얼굴표정 연구의 필요성이 증가하고 있다. 그리고 지금까지의 많은 얼굴 표정 연구들은 정적인 얼굴사진 위주로 이루어졌다. 그러나 실제 사람들은 단적인 얼굴표정만으로 정서를 인식하기 보다는 미묘한 표정의 변화나 얼굴근육의 움직임 등을 통해 정서상태를 추론한다. 본 연구는 동적인 얼굴표정이 정적인 얼굴표정 보다 정서상태 전달에서 더 큰 효과를 가짐을 밝히고, 동적인 얼굴 표정에서의 눈과 입의 정서인식 효과를 비교해 보고자 하였다. 이에 따라 15 개의 형용사 어휘에 맞는 얼굴 표정을 얼굴전체, 눈, 입의 세 수준으로 나누어 동영상과 스틸사진으로 제시하였다. 정서 판단의 정확성을 측정한 결과, 세 수준 모두에서 동영상의 정서인식 효과가 스틸사진 보다 유의미하게 높게 나타나 동적인 얼굴 표정이 더 많은 내적정보를 보여주는 것을 알 수 있었다. 또한 얼굴전체-눈-입 순서로 정서인식 효과의 차이가 유의미하게 나타났으며, 부정적 정서는 눈에서 더 잘 나타나고 긍정적 정서는 입에서 더 잘 나타났다. 따라서 눈과 입에 따른 정서인식이 정서의 긍정성-부정성 차원에 따라 달라짐을 볼 수 있었다.

In the result of Industrial development. largeness and highness of techniques. a large amount of Information Is being treated every year. Achive informationization. we must store in computer ,all informations written on paper for a long time and be able to utilize them In right time and place. There Is recurrent neural network as a model rousing the output value In learning neural network for characters recognition. But most of these methods are not so effectively applied to it. This study suggests a new type of recurrent neural network to classifyeffectively the static patterns such as off-line handwritten characters. This study shows that this new type Is better than those of before in recognizing the patterns. such as figures and handwritten characters, by using the new J-E (Jordan-Elman) neural network model in which enlarges and combines Jordan and Elman Model.

The purpose of this study was to evaluate the effect of parenting stress on marital conflict in dual earner couples with children in early childhood. Actor and Partner Interdependence Model (APIM) was conducted in order to identify how parenting stress affect husband and wife, respectively and how this make the actor effect as well as the partner effect regarding the marital conflict. The research was conducted with 629 married couples from the forth wave of the Panel Study of Korean Children (PSKC) data. In order to examine the relationships between the variables and to evaluate the appropriateness of the research model, structural equation model was used. The results showed that the parenting stress had significant positive effect on the marital conflict. The partner effect of parenting stress was significantly positive. This result implies that the mutual dependence in dual earner couple's marital conflict and parenting stress should be considered in the process of intervention. In other words, to improve the effectiveness of intervention, practitioners should treat couples together rather than being focused on individuals.

This study examined how the quality of TikTok service affects user satisfaction and continuance intention. This study classified the quality of Tiktok service as service quality, information quality, and system quality, and examined the effect of each dimension on user satisfaction and continuous intention. In addition, the role of perceived commercial viability was also examined. In this study, we conduced an online survey on 237 Chinese TikTok users and analyzed the data with the SEM and a moderated regression analysis. Results are as follows. First, information quality and system quality are positively associated with user satisfaction. Second, information quality is positively associated with continuance intention. Third, user satisfaction fully mediates system quality and continuance intention, and it partially mediates information quality and continuance intention. Fourth, although user satisfaction is positively associated with continuance intention, commercial viability does not function as a moderating variable.

The purpose of this paper is to evaluate visitor satisfaction(VS) in waterfront parks in terms of resources, facilities, embodiment of theme(ET), site composition(SC), relaxation activity space(RAS), and dynamic activity space(DAS), which are supply-side components in the planning process of waterfront parks, in order to answer the research question; 'How is visitor satisfaction of waterfront parks determined?' After reviewing the literature on parks and the building process of waterfront parks in Korea, we constructed a conceptual framework and have ascertained a research hypothesis. We had obtained data through a questionnaire survey from 327 visitors at waterfront parks, based on the quota sampling method. We have analyzed the data using the path analysis method. We found that: 1) The direct effects of resources and facilities on VS turned out to be 0.273 and 0.306, respectively while the indirect effects are 0.114, 0.170, respectively. 2) The direct effects of SC, as a component of the planning process on VS, turned out to be 0.243 while that of ET had no affect on VS. The indirect effect of ET and SC on VS turned out to be 0.059 and 0.018, respectively. 3) The direct effects of RAS on VS turned out to be 0.129 while the indirect effects of RAS and DAS on VS turned out to be 0.002 and 0.017, respectively. 4) The size of causal effect, in order, were facilities, resources, SC, RAS, ET, and DAS. 5) Resources and facilities, as a park foundation, compose 64.84 percent of total causal effect while ET and SC have 24.04 percent and RAS and DAS have 11.12 percent, respectively. These research results imply that: 1) Existing waterfront parks should be regenerated with the embodiment of water related theme and with improved facilities for RAS and visitor programs and/or facilities for DAS. 2) The relationship among ET, SC, RAS and DAS should be increased for a significant improvement of VS, and 3) A process-oriented approach turned out to be highly useful for the development of substantive theory and methodology. It is recommended that a structural equation model on waterfront parks be developed using more empirical data and this approach be widely applied for testing its validity.

This study examined the mediation effects of sensation seeking on the relationship between internal and external boredom proneness and game addiction. For this study, 567 middle school students in Kyungki and Chungcheong were included in the analysis. The results showed that both internal boredom proneness and external boredom proneness were positively correlated with game addiction. Internal boredom proneness was negatively correlated with all subscales of sensation seeking, whereas external boredom proneness was positively correlated with boredom susceptibility and disinhibition. Sensation seeking was found only to partially mediate the influence of the adolescents' external boredom proneness (independent variable) on game addiction(dependent variable). Based on these results, suggestions for game addiction intervention and future studies were mentioned.
