The purpose of this study was to examine the influences of disability identity on posttraumatic growth and the moderating effects of resilience on the relationship between the two variables in individuals with acquired disabilities who have experienced the trauma of disability in their adulthood. For the purpose, the study surveyed 203 persons who have acquired a disability after the age of 18 years, and then performed a standard multiple regression analysis and a hierarchical multiple regression analysis respectively using data gathered. The results of the study are as follows. First, a higher disability identity resulted in a higher level of posttraumatic growth. Second, when disability identity and posttraumatic growth were positively related, increasing the level of resilience increased the effect of disability identity on posttraumatic growth. Thus on the basis of the results, the study discussed the tasks ahead to form a positive disability identity and increase the level of resilience.

The purpose of this study was to explore whether posttraumatic growth moderates the effects of stress on depression and quality of life in cancer survivors. Data were collected from 173 cancer survivors in Seoul, Gyeonggi, Chungcheong, and Jeolla provinces. We used hierarchical regression to analyze the data. As the results, first, the interaction of stress and posttraumatic growth affected depression and quality of life. It means that even though the levels of stress are high when the levels of posttraumatic growth are high, the levels of depression are lower and the levels of quality of life are higher than posttraumatic growth being low. Second, the interaction of stress and posttraumatic growth affected two sub-factors of quality of life. We discussed the interventions to reduce depression and to increase quality of life.

Based on the affective event theory, the purpose of the study is to examine the effect of the individual difference regulatory focus on the process in which the work events affect job engagement under organizational circumstances. To this end, 232 financial workers were surveyed on positive events, positive affects, regulatory focus and job engagement. The results of the analysis are as follows. First, the positive events generated positive affects and showed positive influence on job engagement. Second, the effect of positive affects on job engagement has been shown to be discriminatory depending on the level of regulatory focus. The higher the level of promotion focus, the stronger the effect on job engagement of positive affects, and the higher the level of prevention focus, the weaker the effect on job engagement of positive affects. Third, the moderated mediated effect was found to be significant only in the prevention focus. The magnitude of indirect effects on job engagement by positive events was found to be weakened when the prevention focus was high. Finally, the implications and future research issues were discussed.

This study aim to demonstrate and categorize the status of level of mobile information utilization of the 2030 youth generation, and to identify factors that may affect the digital divide within the generation. For this purpose, 1779 data were analyzed using materials for the 2018 digital divide survey in Korea Ministry of Science and ICT. According to the level of information utilization, the consumers were categorized into three types : reference group (46.5%), high utilization group (27.2%), and low utilization group (26.3%). There were statistically significant differences in demographics variable, consumer capabilities, living satisfaction by type of consumer. In addition, the factors influencing the digital divide of the high utilization group and low utilization group were identified compared to the reference group. It is meaningful that this study confirmed the actual gap of information utilization and raised the possibility of the digital divide within the 2030 youth generation.

This study was conducted to investigate the relationship between performance level and ego orientation and task orientation, which are sub-factors of achievement goal orientation, targeting the Korean youth badminton national team. Accordingly, two null hypotheses were established and tried to verify that there would be no difference in ego orientation and task orientation according to the performance level of the badminton youth representative players. A total of 92 middle and high school students were divided into upper and lower performance groups, and the differences between ego orientation and task orientation were investigated, respectively. For the measurement, We used sports achievement goal orientation (task and ego orientation in a sports questionnaire, TEOSQ). Data were analyzed by performing frequency analysis, reliability analysis, and independent t-test. As a result, there was no statistically significant difference in both the ego orientation and task orientation between the upper and lower groups of performance. We discussed based on the research results.

This study aims to investigate peer socialization processes on early adolescents' prosocial behaviors in friendship networks. A longitudinal social network model (SIENA) was used to disentangle socialization process in prosocial behavior. Participants were fourth and fifth graders in South Korea from 39 elementary school classrooms (N=1,040, 48% girls). According to results, students select friends based on similarity in prosocial behavior (peer selection) was found in both prosocial behaviors. Peer influence effects were also observed in prosocial behaviors. Also, moderating effect of social relatedness was significant. In classes with high social relatedness, influence effect of prosocial behavior was significant. As a contrast, prosocial behavior was not socialized in classes with the low social relatedness. Results suggest that peernetwork play a critical role in the co-evolution of friendships, and prosocial behaviors. Findings yielded the importance of the socialization process and promoting healthy peer socialization environment.

The purpose of the current study is to report a part of our larger project whose focus is to understand a relationship between students' units coordination and K-12 school mathematics. In particular, in this paper we report how students who exhibit distinct levels of units coordinations used their knowledge of proportion to solve quadratic function problems of the form y = ax². To this end, three 7th grade students all of whom assimiliated whole number problem situations with three levels of units but showed different levels for fraction problems were chosen. We carried out clinical interviews not only to understand their ability to coordinate units but to understand their problem solving process of proportion and the quadratic function problems. The analysis suggest that their abilities to coordinate units influenced their ways to solving proportion problems, and in turn influenced their ways to solve the specific form of quadratic functions. We have finalized our study by discussing how students' ability to construct and coordinate units, their proportion knowledge, and their knowledge associated with expressing the specific type of quadractic functions could be related.

This study was conducted to examine whether hasty behaviors were structurally maintained even after the expansion of age zones and to determine the characteristics of hasty behaviors by gender and age. To this end, an analysis was made of the data of 591 respondents after excluding the insincere respondents from the 602 adults who had replied to the survey on hasty behaviors. Its results showed that a hasty behavior consisted of 5 factors regardless of age. Even when age was expanded, a hasty behavior maintained its structural stability. On the other hand, women were higher than men in the average score of hasty behaviors. Lastly, hasty behaviors decreased with the increase in age. The gender differences in hasty behaviors were analyzed on the basis of those in time pressure perception and task processing method. They were presented to show that the speed reduction by age increase is related to psychological mechanism as well as bodily function.

This study analyzes whether the network characteristics lead to differences in innovation performance between inventors, using the case of Samsung Electronics and Hyundai Motor Company which have applied for the most patents in the electronics and automobile industries while showing significant differences in the degree of collaborative invention. The more inventors an inventor is connected with in the network, the higher innovation performance is achieved. While existing literature addressed intra- / interindustry, and intra- / inter- group spillovers at the organizational level, this study extends this discussion to the inventor level. This study newly introduces spillover pools from network components and then constructs spillover pools in three dimensions of the group, the industry, and the network component. The study analyzes the effects of each spillover pool on invention performance of an individual inventor and compares the effects between spillover pools. At the inventor level, the innovative effects of spillover pools were confirmed. The results of this study suggest that the inventor's network characteristics and spillover pools can be used to predict the inventor's innovation performance.
