The primary purpose of the present study is to provide the sources to improve the mathematical problem solving performance by analyzing the effects of the belief systems and the misconceptions of the middle school students in solving the problems. To attain the purpose of this study, the reserch is designed to find out the belief systems of the middle school students in solving the mathematical problems, to analyze the effects of the belief systems and the attitude on the process of the problem solving, and to identify the misconceptions which are observed in the problem solving. The sample of 295 students (boys 145, girls 150) was drawn out of 9th grade students from three middle schools selected in the Kangdong district of Seoul. Three kinds of tests were administered in the present study: the tests to investigate (1) the belief systems, (2) the mathematical problem solving performance, and (3) the attitude in solving mathematical problems. The frequencies of each of the test items on belief systems and attitude, and the scores on the problem solving performance test were collected for statistical analyses. The protocals written by all subjects on the paper sheets to investigate the misconceptions were analyzed. The statistical analysis has been tabulated on the scale of 100. On the analysis of written protocals, misconception patterns has been identified. The conclusions drawn from the results obtained in the present study are as follows; First, the belief systems in solving problems is splited almost equally, 52.95% students with the belief vs 47.05% students with lack of the belief in their efforts to tackle the problems. Almost half of them lose their belief in solving the problems as soon as they given. Therefore, it is suggested that they should be motivated with the mathematical problems derived from the daily life which drew their interests, and the individual difference should be taken into account in teaching mathematical problem solving. Second. the students who readily approach the problems are full of confidence. About 56% students of all subjects told that they enjoyed them and studied hard, while about 26% students answered that they studied bard because of the importance of the mathematics. In total, 81.5% students built their confidence by studying hard. Meanwhile, the students who are poor in mathematics are lack of belief. Among are the students accounting for 59.4% who didn't remember how to solve the problems and 21.4% lost their interest in mathematics because of lack of belief. Consequently, the internal factor accounts for 80.8%. Thus, this suggests both of the cognitive and the affective objectives should be emphasized to help them build the belief on mathematical problem solving. Third, the effects of the belief systems in problem solving ability show that the students with high belief demonstrate higher ability despite the lack of the memory of the problem solving than the students who depend upon their memory. This suggests that we develop the mathematical problems which require the diverse problem solving strategies rather than depend upon the simple memory. Fourth, the analysis of the misconceptions shows that the students tend to depend upon the formula or technical computation rather than to approach the problems with efforts to fully understand them This tendency was generally observed in the processes of the problem solving. In conclusion, the students should be taught to clearly understand the mathematical concepts and the problems requiring the diverse strategies should be developed to improve the mathematical abilities.

This study examines the effectiveness of CSR through the expectancy disconfirmation theory. The change of CSR belief after a corporate social irresponsibility (CSIR) crisis was investigated in terms of activity timing (proactive activities before CSIR crisis/reactive activities after CSIR crisis). Study 1 explores the influence of CSR belief perceptions formed through usual CSR activities on CSR belief decline after a CSIR crisis and the moderating effect of CSR activity types. Higher CSR belief perceptions are formed through usual CSR activities that result in a large CSR belief decline. The moderating effect of CSR activity types on CSR belief decline is found. Volunteer activity has the strongest depending effect on CSIR crisis. Study 2 explores the influence of CSR belief perceptions formed through CSIR crisis on a CSR belief incline after CSR activities and the moderating effect of CSR activity types. The lower CSR belief perception after CSIR crisis results in a high CSR belief incline after CSR activities. The moderating effect of CSR activity types on CSR belief incline is found. Cause-related marketing has the strongest overcoming effect on a CSIR crisis.

Teachers' teaching behavior is directly influenced by teachers' belief, and students' belief system is directly influenced by teachers' teaching behavior. There has been a question whether curriculum of teacher training university could help preservice teachers form positive belief system. The purpose of this study was to address this issue empirically. First, a questionnaire about mathematical belief was given to freshmen preservice teachers. They generally showed positive belief about mathematics to the degree that is not satisfactory and responded most positively in the sub-area of teaching mathematics from three sub-areas of mathematics itself, studying mathematics, and teaching mathematics. After studying a mathematical philosophy course, the freshmen preservice teachers were given the same questionnaire that they responded before studying the course. Belief about mathematics itself was changed very positively, and increase in the sub-area of mathematics itself was the largest. These results show that the mathematical philosophy course helped preservice teachers form positive belief system in mathematics.

This study examined the development of children's theory of mind by types of false-belief tasks and various mental states. Seventy six 3-, 4-, 5- and 6-year olds were asked to infer others' minds or choose other's behaviors. Ten tasks, including two picture book tasks, were used to tap the children's understanding of various mental states. Results showed that children did well in their understanding of diverse perception and desire, but they did poorly in emotional inference based on false-belief, and second order false-belief. Children performed better in picture book tasks than in classical tasks for the understanding of false-belief and false-belief based emotion.

The purpose of this study is to investigate the relationship between irrational belief and psychopathology. The Korean version of Symptom Check List-90-R and Irrational Belief Test were administered to 621 high school students in group. The author used Pearson correlation coefficiency and multiple regression analysis to seek the regression patterns of the irrational belief. The results were as follows. 1) Most of the subscales of the SCL-90-R and Irrational Belief Test were correlated significantly. 2) In multiple regression analysis, the irrational belief associated with anxious overconcern was the most predictable variable for psychopathology.

Belief revision involves integrating new information with the current belief. It is a ubiquitous human activity. A critical feature of belief revision lies in its sequential nature. Railroad system can be described as organic. Engine drivers take a great role in this system. Recently, Hogarth and Einhorn(1992) have Posited a belief-adjustment model for updating beliefs. Based on a sequential anchoring and adjustment strategy, the model is important fro decision makers. The sequential nature of information processing is affected by some task variables. This will be mainly explained in this paper. The purpose of this study is to examine the engine drivers' belief revision process and factors which influence on the belief revision process. The factors are the order and the experience. Thereby, this will contribute to the study of engine drivers' behavior. The result of this study is summarized as follows. The order effect due to the order of presentation of the evidence exist. The difference of belief revision is due to The experience level.

Purpose: The purpose of this study was to investigate and compare human papillomavirus (HPV) vaccination status associated with HPV health belief and knowledge between male and female highschool students. Methods: In the winter of 2012, 183 students responded to self-administered questionnaires, and t-test, ${\chi}^2$-test, and ANOVA were used for data analysis. Results: There were significant differences in the experiences of hearing about HPV vaccination, source of HPV information, experience of being vaccinated with HPV vaccination, reason for HPV unvaccination and vaccination intention by gender. The mean scores for health belief of HPV vaccination were 1.72 (total score: 4) in men and 2.31 in women. There were significant differences in HPV health belief (t=-5.14, p<.001). The mean scores for knowledge of HPV vaccination were 0.08 (total score: 1) in men and 0.12 in women, but there were no significant differences in HPV knowledge (t=-1.62, p=.108). There were positive associations between HPV health belief and knowledge in women (p=.02). Conclusion: This study showed different HPV vaccination status, health belief and knowledge in gender. The results indicate a need to consider levels of health belief and knowledge of HPV vaccination in target populations of highschool students when planning a HPV related education program.

The aim of the study was to develop the scale for measuring prospective teacher's belief on workplace spirituality. The researchers revised the 'Workplace Spirituality Scale for Early Childhood Teacher (Lim, 2014)' into the draft of 'Workplace Spirituality Belief for Prospective Early Childhood Teacher (WSBS_PECT)' and then validated the draft of WSBS_PECT statistically. The data were collected from 664 prospective teachers participating 5 early childhood teacher programs. EFA, CFA, Correlations and some statistical methods were carried out for testing validity and reliability of the scale. As a result, the WSBS_PECT with 21 items of 4 factors - i.e. 'awareness of meaning of life', 'belief on calling for ECE teacher job', 'belief on relationships in community', and 'belief on membership in community'- was developed and identified as a available measurement for prospective childhood teachers.
