Recently, the demand to interpret image data with artificial intelligence in various fields is rapidly increasing. Object recognition and detection techniques using deep learning are mainly used, and video integration analysis to determine unstructured object recognition is a particularly important problem. In the case of natural disasters or social disasters, there is a limit to the object recognition structure alone because it has an unstructured shape. In this paper, we propose intelligent video integration analysis system that can recognize unstructured objects based on video turning point and object detection. We also introduce a method to apply and evaluate object recognition using virtual augmented images from 2D to 3D through GAN.

Objective: This study aimed to investigate the influence of child care center managers' coaching leadership on teachers' motivational self-concepts via middle managers' coaching leadership. Teachers' motivational self-concepts consisted of personal self-concept and social self-concept. Methods: A questionnaire survey was conducted on 475 child care center teachers regarding teachers' recognition of the coaching leadership of managers and middle managers and motivational self-concepts of teachers. To analyze the collected data, the path was examined through descriptive statistics, correlation analysis, structural analysis using Amos, and the mediating effect was confirmed by conducting the Sobel Test. Results: The middle manager's coaching leadership was found to mediate the pathways from the manager's coaching leadership to the teacher's social self-concept, but did not mediate the personal self-concept of teachers. Conclusion/Implications: This study showed that the manager's coaching leadership was mediated by the middle manager's coaching leadership and that the manager's coaching leadership had an influence on the social self-concept of teachers. These results imply that both managers and middle managers need to develop coaching leadership skills in order to improve the motivational self-concept of teachers, which is important for work efficiency at child care centers.

In this paper, we propose a new PCA-based LDA Mixture Algorithm(PLMA) for real-time face recognition system. This system greatly consists of the two parts: 1) face extraction part; 2) face recognition part. In the face extraction part we applied subtraction image, color filtering, eyes and mouth region detection, and normalization method, and in the face recognition part we used the method mixing PCA and LDA in extracted face candidate region images. The existing recognition system using only PCA showed low recognition rates, and it is hard in the recognition system using only LDA to apply LDA to the input images as it is when the number of image pixels ire small as compared with the training set. To overcome these shortcomings, we reduced dimension as we apply PCA to the normalized images, and apply LDA to the compressed images, therefore it is possible for us to do real-time recognition, and we are also capable of improving recognition rates. We have experimented using self-organized DAUface database to evaluate the performance of the proposed system. The experimental results show that the proposed method outperform PCA, LDA and ICA method within the framework of recognition accuracy.

This study identifies the factor structure of sociocultural attitudes toward appearance, appearance management attitudes, fashion behaviors, and the effects of sociocultural attitudes toward appearance and appearance management attitudes on fashion behaviors. Questionnaires were administered to 255 college students living in Daegu Metropolitan City and Kyungbook province. The data collected were analyzed using frequency, factor analysis, multiple regression, and t-test. The findings were as follows. Sociocultural attitudes toward appearance were composed of two factors (body internalization and appearance recognition). Appearance management attitudes were composed of four factors (shape management recognition, weight management, appearance satisfaction, and health care). Fashion behaviors were composed of six factors (convenience, fashion following, self-satisfaction, attractiveness, pursuit of change, and pleasure). Gender of college students showed a distinction between the sub-variables of sociocultural attitudes toward appearance factors (body internalization) and appearance management attitudes (weight management) and fashion behaviors (convenience, fashion following, self-satisfaction, and pleasure). Women had more desire to have a similar looking body of TV celebrities than men. The effects of sociocultural attitudes toward appearance and appearance management attitudes on each fashion behavior variables (convenience, fashion following, self-satisfaction, attractiveness, pursuit of change, and pleasure) were explained by the factors of body internalization and appearance recognition, and weight management, appearance satisfaction, and health care. College students produced fashion appropriate to the situation. Strategies of fashion marketing based on these results are as follow. Through mass media, advertisers help university students realize a healthy outlook and create a social atmosphere that can promote healthy body attractions.

The survey was carried out with a random sample of adults living in Busan and Gyeongnam. The collected material is used by the SPSS version 12.0. The frequency, percentage, examination were applied for studying. We separated the group of safety, general management, real hair management according to characteristic about scarp and hair problems. There is highly understanding about the hair problem that if someone has really sensitive scalp or who has dandruff or who has thin hair or who has someone has hair losing problem in their family. Usually, the group has highly understanding of hair problem, they consult about their hair and scalp with expert. They have a really good attention about the mass media(TV, Internet, Newspaper, Magazine) for scalp and hair health. They reduce using hair products. They always read hair product brochure first and use it. They don't eat fast food frequently. The survey has shown high levels of article. Now the research showed us that s have a strict connection between self-recognition and scalp treatments. That means someone has understanding hair problem then start treatment first.

A EAARS(Electronic Attendance-Absence Recording System) is the important LSS(Learning Support System) for blending a on-line learning in the face-to-face classroom. However, the EAARS based on the smart card can not identify a real owner of the checked card. Therefore, we develop the CS(Client-Sever) system that manages the attendance-absence checking automatically, which is used the self-organizing neural network for the face recognition. A client system creates the ID file by extracting the face feature, a server system analyzes the ID file sent from client system, and performs a student identification by using the Recognized weight file saved in Database. As a result, The proposed CS EAARS shows the 92% efficiency in the CS environment that includes the various face image database of the real classroom.
