The purpose of this study was to find out the psychological characteristics of the unemployed, and their children's negative emotions and behavioral changes in the context of the increasing family dysfunction caused by the IMF economic crisis. The subjects were 184 public labor workers in Busan. They answered the questions about the psychological characteristics of themselves and their children, and their children's behavioral changes. Frequency analysis, $\chi$$^2$ test and logistic regression were used for data analyses. The results were as follows. The unemployed showed high levels of negative emotions and perceived their social supports as low. As well, they interpreted their quality of life as poor. They perceived their economic difficulty as high and the perception was influenced by negative emotions as well as the economic situation. Children of the unemployed showed middle levels of negative emotions, and positive and negative behavioral changes. These changes were influenced by their parent's psychological characteristics. In light of these results, psychological counseling services from social welfare centers are needed to be more actively supporting the families of the unemployed.

Purpose: The purpose of this study was to investigate the correlation between the visual perception ability and the static dynamic balance ability in health elderly. Method: The Motor Free Visual Perception Test-Row Score(MVPT-RS) and MVPT-Process Time(MVPT-PT) were used for evaluating the visual perception abilities. Assessment of the balance ability was taken by using Good Balance System. In the assessment using Good Balance System, X, Y coordinate speed, anterior-posterior direction, medial-lateral direction and Velocity Movement(VM) in standing posture when eye open were measured as static balance abilities. Thirty-seven healthy elderly who live in Gwangyang participated in the experiment for 2 months, from October to November 2010. Results: 1. There were statistically significant differences of MVPT-RS, MVPT-PT, NSB-X, NSB-Y, NSB-VM, OLB-X, and OLB-VM based on the gender(p<0.05). 2. The negative correlations of MVPT-RS:NSB-Y(r=-0.354), MVPT-RS:OLB-X(r=-0.4), MVPT-RS: OLB-Y(r=-0.371), but positive correlations of MVPT-PT:DTB-T showed a statistical significance(r=0.45, p<0.05). 3. The positive correlations of NSB-X:NSB-Y(r=0.54), NSB-X: NSB-VM(r=0.848), NSB-Y:NSB-VM(r=0.531), OLB-X:OLB-Y(r=0.876), OLB-X:OLB-VM(r=0.872), and OLB-Y:OLB-VM(r=0.787) showed statistical significances(p<0.05). Conclusion: These results showed that the visual perception ability was correlated with some balance ability in health elderly. Especially the perception test process time(MVPT-PT) has closely related with the DTB-T. The visual perception ability is considered as a factor on the balance ability in health elderly. Further study will focus on the development of improving program of visual perception ability as an improving method of balancing ability in health elderly.

There have been a series of mixed reviews on the 'untact work' which was implemented for the safety of the organizational members from Covid-19. This study reports a follow-up study with a quantitative approach to issues identified by in-depth interviews with workers and managers who have experiences in work from home. To compare the views of workers and managers on untact work, 264 workers and 141 managers were surveyed. An analysis of agreement, congruency, and accuracy on the basis of the co-orientation model shows that workers are more positive about the untact work than managers and that managers are found to have a negative perception on untact work. This seems to be a burden on workers. More specifically, managers and workers show significant perception gaps on the issues of unfair evaluation and work-life balance. The results imply that organizations need to make efforts to minimize the perception gaps between workers and managers. This would bring about benefits from untact work.

The recent increase in the production of 3D contents allowed viewers to experience various 3D contents. However, some of the viewers did not experience 3D depth well. Several researches were done in past to measure viewers' 3D depth perception, but these researches were done with certain limitations. In this paper, we measured viewers' 3D depth perception and recovery rate in relation with the changes in binocular disparities, saturation, and brightness values after subjects' watching 2D/3D contents. The results showed that when viewers watched the 3D content with positive binocular disparities for 42 minutes, viewers felt that the object seemed to have moved further forward than it was before; with 3D content with negative binocular disparities, viewers felt that the object seemed to be moved backwards. We found that the locational differences of the object in positive disparities were greater than those in the negative binocular disparities. The recovery rate was computed by comparing two measured values of before and after watching 3D contents for 30 minutes. On average, after 30-minute break, viewers showed roughly 50 % of recovery rate.

Objective : The purpose of this study was to investigate the association among the fear of COVID-19, depression, risk perception, health belief, and preventive health behaviors related to COVID-19 among university students in Jeonbuk region. Methods : A cross-sectional study was conducted using an online questionnaire survey. The questionnaire included The Korean Version of Fear of COVID-19 Scale, the Korean Version of the Patient Health Questionnaire-9, and measurement tools adapted from previous studies for risk perception, health belief, and preventive health behaviors of subjects. We analyzed data using Pearson's correlation analysis, confirmatory factor analysis, and path analysis using SPSS 22 and AMOS 21. Results : The fear of COVID-19 showed significant positive influence on health belief as well as risk perception. Depression had a significant negative impact on preventive health behaviors and risk perception. Health belief showed a significant positive impact on preventive health behavior. Conclusion : Rresults revealed that the higher the level of depression was, the lower risk perception and performance of preventive health behavior were among university students in Jeonbuk region. As the level of the fear of COVID-19 became higher, the level of health belief and risk perception became higher. The higher the level of health belief was, the higher the performance level of preventive health were. Thus, it is prudent to increase the level of health belief, and lower the level of depression, in promoting preventive health behavior.

This study examined the factors influencing the purchase intention of meat substitutes. A survey was conducted on 589 consumers in Korea (297 people) and China (292 people). The perception of meat substitute foods was lower in Korean consumers than in Chinese consumers, but there was no significant difference. The purchase intention of meat substitute foods was lower in Korean consumers than in Chinese consumers (p<0.01). Korean consumers' perception of meat substitute foods was higher in males than in females (p<0.01). The purchase intention of meat substitute foods also showed the same trend (p<0.001). Chinese consumers' perception of meat substitute foods was higher in males than in females. The overall purchase intention of meat substitute foods was significantly higher in males than in females (p<0.05). The perception of meat substitute foods by Korean consumers' was higher in their 40s and 50s than in their 20s and 30s. The purchase intention of meat substitute foods was also high in their 40s and 50s (p<0.01). On the other hand, the perception of meat substitute foods by Chinese consumers' was higher in their 20s and 30s than in their 40s and 50s (p<0.01). The purchase intention of meat substitute foods also showed the same trend (p<0.01). Korean consumers' perception of meat substitute foods had a significant positive effect on the purchase intention of meat substitutes (p<0.001). Chinese consumers' perception of meat substitute foods also had a significant positive effect on the purchase intention of meat substitute foods (p<0.001). Overall, food technology neophobia has a significant negative effect on the purchase intention of meat substitutes (p<0.05).

As the teacher-centered education is transformed into learning-centered education, the active knowledge construction of learner becomes important. Along with this change, project-based learning is receiving attention. However, there are many problems to apply the results of research to pre-service teachers because most of the previous studies have focused on elementary middle high school students. Therefore, this study examined the changes in perceptions of pre-service mathematics teachers while project-based learning progressed for one year. Pre-service mathematics teachers had less experience with project-based learning than group discussions, group activities. Also their perceptions was classified as five factors: 'Instructional effects', 'Application and participant of project-based learning', 'Achievement', 'Diffusion of project-based learning', 'Student motivation'. Pre-service mathematics teachers responded positive changes in perception that project-based learning could be motivated to students but they responded negative changes in perception that project-based learning could be distributed to school. They responded positive changes in perception that teachers can show their achievements by project-based learning but they responded negative change in perception that teachers would be fun to apply project-based learning. Also, they responded positive changes in perception that teachers and students were easy to apply or utilize project-based learning.

The purpose of this study is to establish the social support system for social integration by analyzing the effect of multicultural experiences on multicultural perception and stereotype and the meditating effect of multicultural perception. The research result is summarized as follow : First, multicultural perception is differently influenced according to multicultural experiences. That is, multicultural experiences have found to have the positive effect on multicultural acceptance and the negative effect on rejection about other cultures or prejudice about other cultures. Second, the result which analyzed the effect of multicultural perception on stereotype has found that acceptance about other cultures doesn't have any effect on stereotype. However, it can be found that the prejudice and rejection about other cultures are verified to be the variables which have the positive effect on stereotype. Third, the result which analyzed the direct effect of multicultural experiences on stereotype and the indirect effect through multicultural perception has found that multicultural experiences don't have any direct effect on stereotype, but do have the indirect effect through multicultural perception. With the help of information technology.

This study aimed to investigate the changes of emotional perception biases according to the level of social phobia and the relationship with visuospatial attention allocation ability. This study used the Korean self-report assessment test (Korean version of social avoidance and distress, K-SAD) to measure the level of social phobia. Moreover, the emotional perception and useful field of view (UFOV) tasks were employed for measuring emotional perception biases and visuospatial attention allocation ability, respectively. A total of 118 participants participated in this experiment, and only 107 (males: 94, females: 13) data were analyzed due to the exclusion of response errors and other statistical problems. The average age of the participants used in the analysis was 21 years (SD: 3.64), and those participants were divided into three groups according to the K-SAD scores. Consequently, all experimental groups showed negative emotional perception biases in the emotional perception task, but the magnitudes of the biases of each group were not significantly different. Furthermore, the positive emotional perception biases were higher at higher levels of social phobia, which could be related to the tendency of interpreting positive stimuli negatively. In the UFOV task, the higher the level of social phobia, the lower the visuospatial attention allocation ability. These results suggest that the deterioration of visuospatial attention allocation ability potentially contributes to the increase of positive emotional perception biases by being difficult to perceive external stimuli. Thus, this paper discusses the potential contribution of visuospatial attention allocation ability to the increased perceptual biases of positive emotions as the level of social phobia increases.
