This study explores the causes of online helping behavior. This study tests the effects of various explanatory factors on the basis of previous studies on helping behavior. These factors include social demographic, situational, motivational, and social capital factors. According to the survey of 475 university students living in Seoul in 2010, age and religion have significant effects on online helping behavior. In addition, the perceived helping opportunity, time and effort cost to help, and social capital factor have significant effects on online helping behavior. Results reveal that the effect of social capital factor is the largest among other variables. However, it is shown that the effects of benefit from helping, empathy, and personal norm are not statistically significant. It is also revealed that the effect of social capital factor is important across all types of online helping behavior except information helping. The policy implications are discussed.

This study was to examine the differences of Korean and Chinese high school students on classroom goal structure(i.e., mastery, performance-approach, and performance-avoidance), help-seeking behavior(i.e., help-seeking, and help-seeking avoidance), and school engagement(i.e., behavioral, cognitive, and emotional), and to identify the mediating role of help-seeking behavior in the links between classroom goal structure and school engagement. The final samples consisted of 290 Korean and 294 Chinese students in high school. Results were as followed. Firstly, Chinese students had a higher classroom mastery goal structure, classroom performance-avoidance goal structure, help-seeking and emotional engagement than Korean students, whereas Korean students had a higher behavioral engagement than Chinese students. Secondly, for Korean students, help-seeking and help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Moreover, for Korean students, help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. While, for Chinese students, help-seeking and help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. Also, for Chinese students, help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Therefore, help-seeking should be promoted in order to improve students' school engagement, and classroom mastery goal structure need to be created in order to encourage students' help-seeking.

With the growing concern over frequent occurrences of criminal events, help-requesting mobile applications have drawn attention. However, existing applications solely focus on providing help-requesting services. Therefore, in this paper, we design and implement a help request and response process which allows users to request help by sending messages and locating their friends, acquaintances and even near-by application users, and to allow help be reached by forwarding messages. This application is composed of three parts: help-requesting, help-responding, and checking-status. This application is developed on the Android platform where we exchange users' longitude and latitude through web server communication. We conducted test to verify the effectiveness of the forwarding function, and it has been confirmed that 93.33% of subjects used the forwarding function to help users at risk.

The importance of helping behavior in our society has been increasing and this study aimed to find the practical strategies to increase helping behaviors with minorities and general public in our communities. Participants(N=156) were randomly assigned to respond to a scenario which measured the intention to help either foreign workers or general public. Also, participants were given the scale of fairness and empathy to respond. The findings of this study demonstrated that (1) empathy and fairness had main effect of the intention to help other persons and empathy and different targets in the unfair perception had interactional effect; (2) the intention to help foreign workers was positively related to fairness and the intention to help general public was affected by empathy. The results showed that according to the perceived unfairness in helping behavior situations, the role of fairness which empathy did not explain was founded. These findings suggest that empathy and fairness in helping behavior are complementary to each other.

The purpose of this study was to analyze the effects of elementary school students' interpersonal stress and attitudes toward help on happiness. The subjects were 171 elementary school students. Data were analyzed using ANOVA, Pearson's correlation analysis, and hierarchical regression analysis. The results of the study are as follows. First, there was a significant negative correlation between interpersonal stress and happiness. Attitudes toward help had a significant positive correlation with happiness. Second, parents and peer relationship stress had significant negative influence on happiness. Third, help seeking attitude toward parents and teacher among the sub-factors of help seeking attitude had a significant positive influence on happiness. Fourth, the relationship between parental stress and happiness showed a significant mediating effect on parents and teacher attitude toward help. The relationship between teacher stress and happiness showed a significant mediating effect on teacher attitude toward help. The relationship between peer relationship stress and happiness had no mediating effect of attitude toward help. Based on these results, we discussed the importance of attitude toward help in the relationship between stress and elementary school students' happiness.

The purpose of this study is to find out factors affecting intentions to seek help for suicidal ideation in Korean Army and to provide a basis for approaches to facilitate formal or informal help seeking for suicidal ideation. A total of 471 Korean soldiers participated in the current study. First, the question of whether suicidal ideation have a significant influence on general help seeking, and whether public stigma and self stigma mediate the relationship between suicidal ideation and general help seeking were examined. According to the results, public stigma and self stigma partially mediated the relationship between suicidal ideation and general help seeking, indicating that suicidal ideation not only has an indirect effect on general help seeking through public stigma and self stigma, but also has a direct influence on general help seeking.

This study analyzed the data from Korea National Health and Nutrition Examination Survey to examine factors associated with help-seeking among Korean adults with suicidal ideation. The results from binary logistic regression analysis showed that being currently married, low family income, and absence of diagnosed clinical depression were negatively associated with seeking help. Gender, age, education, the PHQ total score, and health insurance did not significantly change the probability of seeking help. The future suicide help-seeking intervention should focus on those who are less likely to seek help.
