This paper is concerned with the effective and efficient identification of the gender and motion of humans. Tracking this nonverbal behavior is useful for providing clues about the interaction of different types of people and their exact motion. This system can also be useful for security in different places or for monitoring patients in hospital and many more applications. Here we describe a novel method of determining identity using machine learning with Microsoft Kinect. This method minimizes the fitting or overlapping error between an ellipsoid based skeleton.

This study intended to verify the impact of non-verbal communication of servers in the service industry on the affective path among customer's positive emotion, self-identification, and loyalty(behavioral and attitudinal loyalty). The data of 397 customers of typical fast food restaurants in Busan and Gyeongsangbuk-do area were analyzed with SPSS and AMOS, and the hypotheses were verified through structural equation model after frequency analysis, as well as exploratory and confirmatory factor analysis. According to the empirical analysis, all three components of server non-verbal communication in the service industry, body language, pseudo language, and body appearance, in respective order, had positive (+) influences on the positive emotion of customers. In addition, customer emotion had a positive (+) influence on brand self-identification. Finally, self-identification had a positive (+) influence on behavior loyalty and attitudinal loyalty. This study suggested practical implications and logical implications in the course of developing emotional loyalty for restaurant companies.

This study investigated the effects of young children's learning-related skills and the maternal involvement on academic abilities. The sample consisted of 310 children from 7 child-care centers located in Seoul and Gyeonggi Province. All variables were measured by the teachers and the mothers of surveyed children. The instrument included the Korean Child Development Inventory(K-CDI) for 4 to 6-year olds and Preschool Learning Behavior Scale(McDermott et al 2000) and the questionnaire on mother's involvement about their children's education. The collected data was analyzed by t-test and hierarchical regression using the SPSS Program. The findings are as follows. First, regardless of the family income level, verbal comprehension and numerical abilities were positively associated with their learning-related skills of young children. Second, the interaction effect of learning-related skills and the mothers' involvement on verbal comprehension of young children in the low-income families was observed. However, no interaction effect was seen in terms of learning-related skills and the maternal involvement on verbal comprehension and numerical abilities of young children in the high-income families. These findings highlight the importance of learning-related skills and their mothers' involvement during the preschool period for the low-income family in improving the early academic achievement.

Purpose: This study was conducted to examine the pro-environmental attitude (actual commitment domain, verbal commitment domain, affect domain), behavior to decreased exposure and knowledge of endocrine disruptors by obesity -related profiles (BMI, body fat percentage, visceral fat percentage, skeletal muscle mass percentage, waist circumference, waist-hip ratio). Methods: A cross-sectional study was conducted with 102 nursing students. Data were collected from November to December, 2015 using self-report questionnaires and physical measurements. Data were analyzed using t-test, Pearson correlation and coefficients with SPSS 18.0. Results: The study results showed that actual commitment domain of pro-environmental attitude and behavior to decreased exposure level on endocrine disruptors were significantly related to visceral fat percentage. Actual commitment domain of a pro-environmental attitude was significantly related to body fat percentage. Pro-environmental attitude was significantly related to the behavior to decreased exposure level on endocrine disruptors and knowledge thereof. Conclusion: These findings suggest that visceral fat and body fat percentages were significantly related to the actual commitment domain of a pro-environmental attitude. Therefore, a replication study is recommended to understand the connection between endocrine disruptors and obesity. In addition, developing an education program about endocrine disruptors for nursing students is recommended. In particular, a pro-environmental attitude, especially on actual commitment domain, could be involved as an education program.

Autism spectrum disorder (ASD) is a developmental disorder associated with cognitive and neurobehavioral disorders. It affects the person's behavior and performance. Autism affects verbal and non-verbal communication in social interactions. Early screening and diagnosis of ASD are essential and helpful for early educational planning and treatment, the provision of family support, and for providing appropriate medical support for the child on time. Thus, developing automated methods for diagnosing ASD is becoming an essential need. Herein, we investigate using various machine learning methods to build predictive models for diagnosing ASD in children using facial images. To achieve this, we used an autistic children dataset containing 2936 facial images of children with autism and typical children. In application, we used classical machine learning methods, such as support vector machine and random forest. In addition to using deep-learning methods, we used a state-of-the-art method, that is, automated machine learning (AutoML). We compared the results obtained from the existing techniques. Consequently, we obtained that AutoML achieved the highest performance of approximately 96% accuracy via the Hyperpot and tree-based pipeline optimization tool optimization. Furthermore, AutoML methods enabled us to easily find the best parameter settings without any human efforts for feature engineering.

This article introduces the conceptual framework of self-efficacy and reviewes recent research articles which are related to development of self-efficacy in children. Self-efficacy means personal judgement about one's capability to organize his behavior in a specific situation. Perceived efficacy can have diverse effects on behavior, thought patterns and affective arousal. People acquire their efficacy information from their performance accomplishments, vicarious experiences, verbal persuasion and their physiological states. In this paper, I argue that two factors, psychological and environmental factor, contribute to the development of children's self-efficacy. Specifically reward, attributional feedback, social comparision and goal setting are classified to psychological factor and home environment, school environment and social environment belong to environmental factor. Since not many studies have been done in this area, in this paper I also suggest some directions for future research.

The purpose of this study was to identify differences in cognitive function according to the presence or absence of apraxia and the tasks most relevant to the cognitive function among the various types of tasks in the apraxia test. The subjects were 42 community residents who participated in a cognitive rehabilitation program related to dementia in a Chungbuk area. MMSE-K and BCoS(Birmingham Cognitive Screen) apraxia test were administered to all subjects. The apraxia test includes three types of tasks, gesture production tasks that make meaningful movements according to verbal instructions, gesture recognition tasks that display behavior after make sense of meanings, and meaningless imitation task. Apraxia group(n=30, MMSE-K mean score: 25) showed lower cognitive function than group without apraxia(n=12, MMSE-K mean score: 28). All tasks in the apraxia test showed a significant correlation with cognitive function, but the meaningless imitation task had a negligible correlation. The apraxia test is a good way to assess cognitive function, and it may be more effective to use meaningful behavior to replace cognitive testing.

Snoezelen, multi-sensory stimulation, provides stimulation through the visual, aural, tactile, olfactory, gustatory and proprioceptive senses. Its aim is to be a relaxing, feeling of safety, novelty and stimulation with no expectations for performance. Agitated behavior of people with dementia causes significant problems and distress for cares. The objective of this research study was to test the effects of Snoezelen room on physical and verbal agitated behaviors of people with dementia. Four patients participated five sessions in Snoezelen room of 'F' dementia care facility in Sweden. Assessment instrument was basically used Cohen-Mansfield Agitation Inventory-Short Form to be rated by caregivers on a 5-point frequency scale. Pre-trial and post-trial assessments were carried out during $27^{th}$ Aug.-$27^{th}$ Sept. 2007. Result shows that Snoezelen room has some short-term positive effect on agitated behavior even though there was a considerable variation individuals responded. This result adds to the increasing evidence that Snoezelen could be a therapeutic environment for the elderly with dementia. Further research study, with larger number of participation, and a control group is required to establish more scientific evidence of Snoezelen effects on health outcome.
