Anticipation effect has been used as a traditional skill to enhance the dynamic motion of the traditional 2D animation. Basically, anticipation means the action of opposite direction which performs before the real action step. In this paper, we propose the perception-based video anticipation method to guide a user's visual attention to the important region. Using the image based attention map, we calculate the visual attention region and then combine this map with temporal saliency of video. We apply the anticipation effect in these saliency regions using the blur kernel. Using our method, we can generate the dynamic video motion which has attentive guidance.

This study was to investigate factors influencing the school adjustment according to gender and body mass index (BMI) of middle school students who participated in the 2nd-wave Korea Children and Youth Panel Study (KCYPS). This study used a crosssectional design with secondary analysis with KCYPS. The variables were parental interest, behavioral problem, aggression, attention problem, somatic symptom, social withdrawal, depression, and academic achievement. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. School adjustment was significantly associated with academic achievement high, explaining 11.3~19.1% of the variance in boys. School adjustment was significantly associated with attention problem, explaining 14.9~42.4% of the variance in girls. Factors influencing school adjustment were significantly different according to gender and BMI. To improve the school adjustment, it is necessary to develop gender-specific school adjustment promotion programs according to BMI.

This study analyzes the effect of poverty on child development outcomes including academic achievement, self-esteem, depression/anxiety, attention problems, aggression, and delinquency. The poverty experiences among elementary school children are longitudinally observed during 3 years between the 4th grade and the 6th grade. When development outcomes are compared among persistently poor children, transitory poor children, and non-poor children, academic achievement is found to be significantly different. The analyses of the relationships between the poverty status and developmental trajectories show that academic achievement among non-poor children has improved over time, while the level of poor children's achievement has decreased. The result also shows that problematic behaviors such as attention problems, aggression, delinquency has improved over time among all the children. Yet, the gap between poor and non-poor children has not decreased. The multivariate analyses indicate that the effect of poverty remains statistically significant only for academic achievement after children's individual and familial characteristics are controlled. Past experiences of poverty in addition to the current poverty affect academic achievement and persistent poverty has a stronger effect than transitory poverty on academic achievement, although the findings are not consistent across all the estimated models.

In philosophy of mind, both reductionism and deflationism claim that the problem of mental causation is overstated, but the reason why they claim that way is quite different. On the one hand, for deflationism, since the problem of mental causation is bogus problem we need to focus on epistemology or scientific explanation rather than metaphysics. On the other hand, although the proponents of nonreductionism seem to think of the principles of causal closure of the physical and causal exclusion proposed by Jaegwon Kim as tenable, they do not go with the reductive approach to the problem of mental causation. Instead they stay with the concept of supervenience to overcome mental causation problem that, reductionists think, leads us to the dilemma situation. Of course, deflationists do not think that supervenience is plausible not as much as supervenience physicalists think that it is. If so, in what way and how do deflationists regard the problem of mental causation as a bogus problem? In this paper, I shall examine the most plausible response to mental causation problem, the contemporary version of mind-body problem by critically discussing and clarifying matters concerning the problem.

This study was to examine the effects of young children's temperament and teacher-child relationship on young children's problem behaviors. The subjects of this study were 231 3-, 4- and 5- year old children and their teachers. The collected data were analyzed by correlations and pathway analysis. The results were as follows: First, young children's temperament were found to affect young children's problem behaviors directly and indirectly though teacher-child relationship. 'Negative emotionality' and 'attention span/persistence' temperament were found to be important for externalizing problem behaviors, and 'activity level' temperament to be important for internalizing problem behaviors. Second, teacher-child relationship was found to affect young children's problem behaviors directly and to mediate between young children's temperament and problem behaviors. Additionally teacher-child conflict relationship was found to be the most important variable predicting young children's externalizing and internalizing problem behaviors.

We investigated the influences of 'Circumstance Insensibility', 'Unsafe Driving', 'Incautious Driving', and 'Self-efficacy of Driving', consisting of driving confidence level, on traffic accidents. 1055 drivers conducted Driving Confidence Level Questionnaire, items about their dangerous driving experience and traffic accidents. Among them, after checking the missing items, we analyzed data of 998 drivers. As a result, we found the relation between driving confidence levels and traffic accidents. Specially, 'Circumstance Insensibility' and 'Unsafe Driving' influenced traffic accidents. However 'Circumstance Insensibility' had negative effects, the other side 'Unsafe Driving' had positive effects on traffic accidents. This result means each factor of driving confidence levels have different relation with traffic accidents. 'Incautious Driving' and 'Self-efficacy of Driving' didn't have any effects on traffic accidents in this research. In future, it should be investigated 'Incautious Driving' and 'Self-efficacy of Driving'.

The purpose of this study was to analyze the effects of Semantic Network Program (SNP) instruction on learning achievement and motivation in high school biology classes. For this study, a SNP was designed by applying the recommendations in regard to student attention and satisfaction factors in Keller's ARCS theory. SNP instruction was conducted with an experimental group and a control group, each consisting of 62 high school biology class student. A pretest-posttest control group design was employed. The pre-test was used to analyze the learning achievement test, learning motivation test, and semantic forming test. For 4 weeks the experiment group was instructed using the developed SNP which centered on Keller's attention and satisfaction factors, and the control group was instructed via teacher-centered lectures based on the textbook. It was found that SNP instruction efficiently increased students' biology learning achievement (p<.001). It was also discovered that SNP instruction was effective in increasing Keller's motivation strategies on attention and satisfaction factors (p<.001). In addition, SNP instruction positively affected students' semantic formation (p<.001) and learning content retention (p>.05) in the heredity unit by aiding students in the area of active multimedia learning. An in depth interview with students in the class using SNP instruction showed that material learned via this method in biology had longer retention of problem-solving methods. Consequently, SNP instruction according to motivation strategies may high school biology teachers with meaningful teaching-learning methods strategies for the unit on heredity.

본 논문에서는 인과지도의 작성자와 독자 간의 심리적 격차에 관하여 분석하고자 한다. 먼저 기존에 연구되어 왔던 소산효과(dissipation effects)와 희석효과(dilution effects)는 인과지도를 작성하는 사람이 아니라 인과지도를 이해하는 사람에게 적용되는 심리적 경향이라는 점을 이 논문에서 지적한다. 소산 효과란 인과고리의 길이가 길어질수록 인과관계의 강도를 낮게 인식하는 심리적 경향을 의미한다. 희석효과는 여러 개의 인과관게가 존재할수록 특정 인과관계의 강도를 낮게 인식하는 심리적 경향을 의미한다. 이들 심리적 경향과는 달리 집중 효과(concentration effect)가 인과지도 작성자의 심리적 경향을 보다 잘 설명하는 것으로 실험 결과 분석되었다. 집중 효과란 주의를 집중하는 영역에 대하여 많은 인과관계를 생각하고, 인과관계의 강도 역시 강하게 생각하는 심리적 경향을 의미한다. 인과지도의 작성자 즉 시스템 컨설팅을 담당하는 사람들에게는 소산효과나 희석효과 보다 집중효과가 더 강하게 작용한다는 것이다. 이러한 심리적 비대칭성이 시스템 다이내믹스 연구자와 그의 고객 간의 의사소통 문제를 야기 시킨다는 점을 본 논문에서 지적한다.
