This study investigated the differential interactive effects of the combination of driving confidence and sensation-seeking on driving anger among different age groups, by using correlation analysis, a hierarchical regression and ANOVAs for the data gathered through the questionnaires administrated in a form of face-to-face interview. The results showed the followings. First, males tended to show higher level in driving anger than females. Second, whereas sensation-seeking was positively correlated with driving anger, age and driving experience were negatively correlated with driving anger, respectively. Third, although there was no significant relationship between driving confidence and driving anger among the drivers aged under 40 years, the drivers aged over 40 years showed higher level of driving anger as their driving confidence increased. Forth, level of sensation-seeking was found to be a strong predictor of driving anger in all age groups. Fifth, driving confidence and sensation-seeking appeared to affect the level of driving anger interactively among drivers aged under 40 years or over 65 years, resulting in higher driving anger only when both the levels of driving confidence and sensation-seeking were high. In contrast, driving confidence and sensation-seeking affected driving anger independently among the drivers aged 30-49 years. Implication and suggestion were discussed.

Workplace bullying is becoming one of social issues. The aim of the present study was to investigate whether the contextual variables(communication climate, social climate) moderate the relations between the individual variables(trait anger, social avoidance) and workplace bullying victimization. The self-report data of 207 office workers(115 men, 92 women) in Seoul and Gyeonggi-do was analyzed. The results of hierarchical regression indicate that trait anger positively predicted men's workplace bullying victimization only when social climate is bad. Social avoidance positively predicted men's bullying victimization only when communication climate is good. There was no moderating effect of the contextual variables among women. Trait anger positively predicted women's workplace bullying victimization only when considering communication climate as a contextual variable. Social avoidance has no significant effect on women's workplace bullying victimization. However, both communication climate and social climate negatively predicted women's victimization. The implications and suggestions for prevention and intervention of workplace bullying were discussed.

Due to climate changes, landslide hazards in the Republic of Korea (hereafter South Korea) continuously increase. To establish the effective landslide mitigation strategies, such as erosion control works, landslide hazard estimation in the long-term perspective should be proceeded considering the influence of climate changes. In this study, we examined the change in landslide-damaged areas in South Korea responding to climate change scenarios using the multivariate regression method. Data on landslide-damaged areas and rainfall from 1981-2010 were used as a training dataset. Sev en indices were deriv ed from rainfall data as the model's input data, corresponding to rainfall indices provided from two SSP scenarios for South Korea: SSP1-2.6 and SSP5-8.5. Prior to the multivariate regression analysis, we conducted the VIF test and the dimension analysis of regression model using PCA. Based on the result of PCA, we developed a regression model for landslide damaged area estimation with two principal components, which cov ered about 93% of total v ariance. With climate change scenarios, we simulated landslide-damaged areas in 2030-2100 using the regression model. As a result, the landslide-damaged area will be enlarged more than the double of current annual mean landslide damaged area of 1981-2010; It infers that landslide mitigation strategies should be reinforced considering the future climate condition.

It is the aim of present paper to examine the effects of experienced violence and observed violence in original family on adaptation in college students. In addition, the degree of contribution of two types of aggression in family were examined. Participants were 220 college students. Among them, those who have experienced violence from mother are 60.3%. And 52.3% reported violence from father. Those who have observed their parents violent behavior are 28.8%. These childhood 'experienced violence' and 'observed violence' was significantly associated early adulthood adaptation. But its effect is dependent on participant's sex. Experienced violence from mother is positively related to confidence in scholastic achievement in female. Experienced violence from father is positively related to trumatic symptoms and trait anxiety in male. On the other hand, observed violence showed significant relationship with traumatic symptoms, impulsivity, depression, self-esteem and trait anxiety. Most importantly, multiple regression analysis showed observed violence explains early adulthood adaptation more significantly than experienced violence. The discussion addressed implications of the findings for future research and for clinical practice.

The purpose of this study was to investigate the relationship of career indecision, job search behavior, and p-j/p-o fit among college graduates based on sub-scales of career indecision (lack of career information, lack of self-clarity, decisiveness, lack of necessity recognition, external Barrier). This study explored the effect of career indecision on job search behavior and p-j/p-o fit and the effect of job search behavior on p-j/p-o fit in longitudinal method. The main results were as follows: 1) Career indecision had negative effect on job search behavior and p-j/p-o fit. In other words, the higher career indecision level is, the less job search behavior is performed. And the higher career indecision level is, the lower p-j/p-o fit perception is: 2) Career indecision was connected with preparatory job search behavior and informal job search behavior: 3) Decisiveness of career indecision was connected with p-j/p-o fit and lack of self-clarity was connected with p-j fit. 4) Job search behavior was not connected with p-j/p-o fit. Thus job search behavior didn't have prerequisite for mediator between career indecision and p-j/p-o fit. The findings are discussed in terms of the implications for further research.

The purpose of this study is to help a recovery of fatigue through the effect of cold immersion treatment after rowing ergometer on blood fatigue substance, MDA and SOD in rowing athletes. For this, 10 subjects participated in this study and we divided them into cold water immersion group (CWI, n=10), non-cold immersion group (NCI, n=10). The exercise program was performed to 2000 m rowing ergometer for maintaining high intensity. The data was collected with regard to the interaction effect of the group and time among the CWI and NCI, ANOVA was used. As the post-hoc test, Bonferroni test was used. The significance was set at .05 and the following conclusions were deduced. For lactic acid, there were the main effect of time (p<.001) and significant difference in the both group (p<.001). Also, LDH were significant difference in the each group (p<.05). For MDA, there were the interaction between group and time (p<.05) and the main effect of group (p<.05) and time (p<.001). SOD were indicated main effect of group and time (p<.05), there was significant difference between each group in the after 30 min recovery (p<.05). Collectively, The results of this study suggest that positive effect on blood fatigue substances, reactive oxygen species and anti-oxidation enzyme through cold water immersion intervention. Therefore, we strongly recommend that performing the cold immersion intervention would be beneficial after high intervention exercise.

This study was attempted to determine the effect of premenstrual syndrome, menstrual pain, attitudes toward menstruation, and quality of sleep on learning immersion in female college students. The subjects of the study were 166 female college students at C University in Gyeongsangnam-do, and data collection was conducted from July 01 to August 31, 2023, using a Google questionnaire. The collected data were analyzed by correlation, multiple regression analysis. Premenstrual syndrome had a significant positive correlation with attitudes toward menstruation(r=.40, p<.001) and menstrual pain(r=.33, p<.001). And sleep quality had a significant positive correlation with menstrual pain(r=.31, p<.001) and learning immersion(r=.24, p=.002). Variables that have a significant impact on learning immersion include 'irregularity in eating' (β =.20, p=.007), 'abdominal massage' to relieve menstrual pain (β=.27, p=.003), and sleep quality (β=.16, p=.038). 'Abdominal massage' to relieve menstrual pain was found to be the best predictor of learning immersion, followed by 'irregularity in eating' and sleep quality. The total explanatory power was 13.9%. Based on the above results, in order to increase learning commitment through mitigation of premenstrual syndrome, education is necessary to seek active countermeasures by increasing various treatments and interest in them, and to have a positive attitude toward menstruation by having proper eating habits.

This study applied a props-based exercise program for 12 weeks to women in their mid-50s in rural areas who complained of back pain, and applied VAS (visual analogue scale), static balance ability left and right, front and back, and sensory movement. Ability Physical stability The left and right, before and after physical changes were investigated. The study subjects were randomly assigned to an experimental group (EG) of 24 people and a control group (CG) of 20 people. For the homogeneity test between the experimental group and the control group, an independent t-test was conducted to analyze the significant difference in average. When homogeneity was secured, two-way ANOVA repeated measures ANOVA was performed. As a result, there was an interaction effect between the group and the 12 weeks period. However, the VAS between periods within the group, static balance ability left and right, before and after, and sensorimotor ability and body stability left and right, before and after showed improved results with significant average differences. After 12 weeks between groups, the experimental group showed significant improvement effects in all variables.
