The purpose of present study was to examine whether the perceived distance is compressed to different extent according to the length of the tool in the object that is not reachable even when using the tool, and whether the perceived distance is compressed according to the tool length only in the object being pointed. In Experiment 1, we found by measuring the egocentric distance that the length of the tool causes the distance to the target to be closer to that of the object placed at a far distance. In Experiment 2, we found by measuring the egocentric distance that when the operated object and the non-operated object coexisted in the visual field, the length of the tool does not affect the distance perception to the non-pointed object. In Experiment 3, we found that the tool length affects only the distance perception of the operated object by measuring the exocentric distance which is the distance between the operated object and the target in the same environment as Experiment 2. The results of present experiment suggest that the compression of the perceived distance occurs at a distance that can not be reached by using the tool, and that the compression of the perceived distance is limited to the pointed object.

The polarization of public opinion by regionalism is one of biggest problems in Korean society. This study attempts to examine the polarization of public opinion between two typical cities representing regionalism and explore the factors influencing on the polarization. The results show that the polarization of public opinion is based on the perceived public opinion rather than the real public opinion. The polarization of public opinion is greater with regional issue than national issue. In general, citizens of Pusan have a conservative bias in estimating other Pusan citizens' opinion and a liberal bias in estimating Gwangju citizens' opinion, whereas citizens of Gwangju have a looking-glass perception in estimating other Gwangju citizens' opinion and a conservative bias in estimating Pusan citizens' opinion. There are no significant differences of the real public opinion and the perceived opinion across three generations. But within each generation, the tendency of public opinion polarization is found between regions and is not shown to change over generations. Regression analyses show that individual's opinion and region are highly predictable variables that explain the perceived public opinion and the perception bias such as false consensus and pluralistic ignorance.

Objective：Present study investigated the relationship between mothers' self-perception and perception of children's problems. Method：Subjects were 63 children, mothers, who visited child & adolescent psychiatric clinic. Their mothers completed Minnesota Mulpiphasic Personality Inventory(MMPI) & Korean Personality Inventory for Children(KPI-C). Correlation between validity scales of mothers' MMPI and validity scales of KPI-C was analysed, and then we divided subjects into two group(High & Low Group) according to the MMPI validity scales, and compared KPI-C's validity scales by student t-test. Result：There were significant positive correlation(r=.30) between K scale of MMPI and L scale of KPI-C, significant negative correlation(r=-.32) F scale of MMPI and L scale of KPI-C. The Means of T scores did show significant difference according to MMPI F, K scales in KPI-C L scale, to MMPI L scale in KPI-C F scale. Conclusion：These results indicated that defensive mothers tend to perceive her child's problems more defensively. However mothers who exaggerate their problem more severely, do not exaggerate their children's problem. Therefore, these result suggested that we should be careful not to underestimate children's problem whose mother elevated in K scale of MMPI.

The purpose of this study is to analyze the long term mediating effects of Self-regulated Learning(SRL) in the Relationships among the Perceptions of Middle School Students on the Democratic Attitude of Parenting(DAP) and their Relationships with Teachers(RT), and their Self-esteem(SE). The data sources were from the first (2010) and the third (2012) Korean Children & Youth Panel Survey(KCYPS). As a result, first, the perceived DAP had significant effects on the students' SE both directly and indirectly through SRL. Second, the perception on RT had indirect effects on their SE mediated by SRL. Third, this pattern in first year continued in two-year-later-SE. This study implies that DAP, RT, and SRL play important roles in the continuous development of adolescents' self-esteem.

In this study, factors influencing the parking policy compliance (i.e. levying a garage option on car buyers) were identified, and then, were applied to the theory of planned behavior. To find out the influence of factors and their path, the study built a parking policy compliance model using structural equation modeling. The independent variables such as attitude, subjective norm, perceived behavioral control had positive effects on the parameter describing the efforts to secure his garage, but the parameter impact on the dependent variable was not significant. In the end, the independent variables affected the dependent variable was not significant. The perceived behavioral control utilizing regulations had positive effects on the parking policy compliance behavior, but past behavior such as street parking and prowling to find a free parking space had a negative effect on parking policy compliance behavior.

Social commerce is a term derived from the fusion of social media and e-commerce. This study aims to classify social commerce benefits as social benefits, confidentiality benefits, economic benefits, and customization benefits based on previous research claims. We also examine the effect of social commerce relationship benefits on trust and flow, and the effect of trust and flow on customer loyalty. Also, we examine how the relationship between trust and customer loyalty, and commitment and customer loyalty varies with self determination. The following are main results of this study. First, social benefits, confidentiality benefits, economic benefits, and customization benefits have significant effects on trust and flow. Second, social commerce trust and flow have a positive effect on customer loyalty. Third, the relationship of social commerce trust, flow, customer loyalty is differ depending on self determination. This study suggests the necessity of differential approach according to self-determination.

The purpose of this study is to investigate the causal relationships among self-efficacy, perceived usefulness, supervisor and peer support, satisfaction, and transfer intentions in the corporate mobile learning. For this study, the web survey was administered to 302 mobile learning learners of the A domestic corporation in South Korea. Structural equation modeling(SEM) analysis was conducted in order to examine the causal relationships among the variables. The results indicated that first, self-efficacy, perceived usefulness, and supervisor and peer support had positive effects on satisfaction. Second, supervisor and peer support and satisfaction had positive effects on transfer intentions. Third, satisfaction mediated the relationship between self-efficacy and perceived usefulness, while it did partially the relationship between supervisor and peer support and transfer intentions. Based on the result of the research, the study proposes organizational environment with cooperative supervisor and peer support should be made in order to improve the level of learners' transfer intentions. In addition, learning strategies that facilitate learners' self-efficacy and mobile information technology acceptance are needed to develop for enhancing the learners' satisfaction.
