The objects real time rendered in the 3D cyber space can interact with each others according to the events which are happened when satisfying some conditions. But to representing the behaviors with these interactions, too many event conditions are considered because each behavior pattern and event must be corresponded in a one-to-one ratio. It leads to problems which increase the system complexity. So, in this paper, we try to physical method based on elasticity force for representing more realistic behaviors of AI fish and apply to the deformable multi-detection sensor, so we suggest the new method which can create the various behavior patterns responding to one evasion event.

Using flight simulator tasks with 48 air force cadets, this research examined the effects of pilots' flight skill and self-esteem on risk-taking behavior in the context of social comparison with their cohorts. Flight skill and self-esteem were assessed for individual cadets and three conditions of social comparison (upward-, downward-, and no-comparison) were devised. Flight simulator situations inappropriate for further approach or landing were designed to assess pilots' risk-taking behavior. Weather conditions in the simulator were inadequate to make a landing and the recommended strategy was to break off the approach and attempt a go-around. In this experiment, pilots' risk taking was measured in terms of their approach altitudes; the lower approach altitudes indicative of the higher risk-taking. Our results showed interaction effects of flight skill, self-esteem, and social comparison on risk-taking behaviors. For pilots who were either high or low in both self-esteem and flight skill, social comparison had no effect on risk-taking behavior. However, pilots with high self-esteem but low flight skill showed more risk-taking behaviors in social comparison conditions. And, pilots with low self-esteem but high flight skill showed risk-aversive behaviors in the downward-comparison condition.

Purpose: To investigate the effect of eating behavior on nutritional status according to temperament type. Methods: One thousand one hundred three preschool children aged 2 to 6 years in Gyeongsan, Gyeongsangbuk-do from April to June 2018 were surveyed about their eating behavior and nutritional status using DBT (Dietary Behavior Test) and NQ (Nutrition Quotient) which are proven tests. The dietary behaviors of the children were classified into four categories: approach avoidance, sensory sensitivity, hyperactivity, and irregularity. NQ scores were divided into five categories: balance, diversity, moderation, regularity, and practice. Results: The mean of the children's age was 3.42 ± 1.4 (596 boys and 507 girls). The percentage distribution of the NQ grade was as follows: 5.5% (highest), 12.5% (high), 47.1% (medium), 22.2% (low), and 12.6% (lowest). The risk group of approach avoidance and sensory sensitivity had significantly (p < 0.001) lower scores than the normal group in balance factor (51.9 ± 12.0 vs. 57.8 ± 15.9 in approach avoidance type, 52.6 ± 17.6 vs. 57.7 ± 15.9 in sensory sensitivity type) and diversity factor (32.5 ± 24.4 vs. 50.1 ± 22.4 in approach avoidance type, and 32.5 ± 24.0 vs. 50.7 ± 22.2 in sensory sensitivity type). The scores of the hyperactivity risk group were significantly lower in moderation factor (78.2 ± 12.1 vs. 81.2 ± 11.9), and those of the irregular risk group were significantly lower in variety (35.9 ± 24.5 vs. 48.8 ± 23.2), regularity (57.6 ± 37.1 vs. 66.1 ± 17.6), and practice (57.1 ± 19.4 vs. 65.1 ± 22.5) factors than the normal group (p < 0.001). Especially, the risk group of approach avoidance and sensitivity type had significantly (p < 0.001) lower intakes of whole grain, fruit, bean and bean products, vegetables, and Kimchi. Conclusion: This present study suggested that the eating behavior based on temperament of demanding preschool children affected food choice resulting in food consumption diversity of children. Therefore, it is important to provide customized nutrition education programs based on temperament type.

The purpose of this study was to investigate learners' reaction behaviors by the type of learning motive when teaching messages were delivered. The subjects of this study were 82 students from Auniversity and Buniversity in the metropolitan area. Students were online collaborative learning. The instructor delivered six messages. Since then, the researchers have measured the learner 's response time and the frequency and level of interaction. And analyzed using an independent sample t-test. As a result, the frequency and level of interaction increased before the message was delivered. The response time to instructional messages was the fastest among the students with performance avoidance goal orientation. Mastery goal orientation students were most sensitive to scaffolding messages. Performance avoidance goal orientation students responded most sensitively to the reminder message. Finally, Mastery goal orientation students had the most action on new topics. And performance approach goal orientation students had the most to do with accuracy and relevance.

This paper propose a fuzzy inference model for obstacle avoidance for a mobile robot with an active camera, which is intelligently searching the goal location in unknown environments using command fusion, based on situational command using an vision sensor. Instead of using "physical sensor fusion" method which generates the trajectory of a robot based upon the environment model and sensory data. In this paper, "command fusion" method is used to govern the robot motions. The navigation strategy is based on the combination of fuzzy rules tuned for both goal-approach and obstacle-avoidance. We describe experimental results obtained with the proposed method that demonstrate successful navigation using real vision data.

This study is to investigate whether averting costs for wearing $anti-PM_{10}$ masks and using air purifiers at home to reduce exposure from $PM_{10}$ are influenced by subjective risk perceptions and/or objective $PM_{10}$ concentration levels, whose estimates will be used to measure the willingness to pay for $PM_{10}$ risk reduction. An empirical analysis was conducted on a sample of 1,224 respondents who participated in the web-based survey in the late October of 2017. As we reflect the potential endogeniety bias in the estimation of averting cost functions of using air purifiers, the coefficients of risk perception were differed by 6~7 times. Respondents. subjective risk perceptions were influenced by individuals' knowledge, attitudes and demographic variables, as well as the levels of $PM_{10}$ concentrations in their residential region. The marginal willingness to pay for risk reductions at the mean levels of their risk perceptions were measured at 1,000 won per month from wearing $anti-PM_{10}$ masks and 6,000 won for using air purifiers respectively.

This current study sought to investigate effects of in-service teachers' achievement goal orientation, organizational citizenship behavior on job-satisfaction and to discuss the improvement of early childhood teachers' achievement goal orientation and organizational citizenship behavior. A total of 178 teachers participated in this study and completed questionnaires. To analyze the data, Pearson's correlation and hierarchical multiple-regression analysis were used. The results were as follows. Firstly, relatively correlation existed between teachers' achievement goal orientation and job satisfaction. Particularly, mastery-approach orientation, performance-approach orientation showed the relatively high correlation with job satisfaction and its sub-scales. Also, teachers' organizational citizenship behavior had relatively positive correlation with their job-satisfaction and its sub-scales. Secondly, teachers' achievement goal orientation and its sub-scale had 38% significant effects on their job-satisfaction. And teachers' organizational citizenship behavior appeared to have 8.6% influence on job-satisfaction. Based on the results, several ways were discussed to develop and improve teachers' achievement goal orientation and organizational citizenship behavior.

The purpose of this study was to identify the patterns of coping with marital conflict and child-rearing stress among mothers of young children. The participants were 166 mothers of children who were between 3 years and 7 years of age, living in the North Kyongsang Province. Paired t-test, ANOVA, Scheffe' test, Pearson's correlation and partial correlation analyses were conducted for this study. The results of this study were as follows. (1) In those situations where the participants experienced marital conflict and child-rearing stress, they were more likely to use an avoidance coping strategy than an approach coping strategy. (2) Among the mothers who were experiencing marital conflict or child-rearing stress, the group that suffered a higher level of stress was more likely to employ an avoidance coping strategy. However, there were no differences in the approach coping behavior by the level of stress. (3) When the level of marital conflict and child-rearing stress were controlled, approach coping behavior with marital conflict was still moderately correlated with approach coping behavior with child-rearing stress.
