  • The aim of this study was to investigate the processes for evaluating the allowable bending stress. The confidence levels and the size-adjustment in standards were reviewed with experimental data. The results show that, (1) KS F 2152 was more strict than others overseas standards due to the higher confidence level. The 5% NTL of bending strengths by a method in KS F 2152 were lower than the overseas standards and more specimens were required for evaluating the structural properties according to KS F 2152. (2) Due to the absence of size-adjustment method in domestic standards, the specified size and the exponential parameters on the size-adjustment equation were reviewed by size factors. The specified size (width: 286 mm, length: 6096 mm), and the exponential parameters (w: 0.29, l: 0.14) will be suitable for developing the allowable bending stress in domestic standard. (3) The size adjusted allowable bending stresses of No. 2 grade Korean pine were lower than the allowable stresses tabulated in KBC even though less strict method (75% confidence level) to calculate 5% value was used. The allowable stresses tabulated in KBC are needed to be reviewed by continuous experimental data.

  • Purpose: This study was conducted to identify the influence of trauma experiences and social adjustment on health-related quality of life in North Korean defectors. Methods: The subjects were 117 North Korean defectors living in B and Y city. The data were collected from September 1 to September 20, 2014, and analyzed by the SPSS/WIN 18.0 program. Results: Significant differences were found in the health-related quality of life with respect to the subjects' education, marriage status, types of dwelling, family types, duration of residence in South Korea, jobs in South Korea and in North Korea, families left in North Korea or other surrounding countries, and subjective health status. Health-related quality of life is negatively related to trauma experiences during escape from North Korea and during their life in South Korea. Health-related quality of life positively is related to social adjustment. The meaningful variables which influenced the subjects'health-related quality include social adjustment, job in South Korea, job in North Korea, current family structure, and trauma experiences in South Korea. Total explanatory power of these factors for health-related quality in North Korean Defectors is 43.0% and social adjustment is the most influential factor. Conclusion: Therefore, in order to enhance health-related quality of life in North Korean defectors, it is necessary for them to increase social adjustment and decrease trauma experiences. In addition, methods are needed to provide job opportunities, better education and family services for North Korean defectors.

  • Purpose: The aim of this study was to examine the correlation between school-life adjustment and suicidal ideation in adolescents by applying the latent growth curve models to the longitudinal data. Methods: This study analyzed three waves of data from the Korean Children & Youth Panel Survey (2014~2016). A total of 1,534 students were included in the analysis. In the application of the latent growth curve models to the longitudinal survey data, we analyzed the initial status and growth changes for each wave, identified individual differences in the general characteristics, and examined the direct relationship between the two latent constructs. Results: The analysis revealed that variations in the initial status and rate of school-life adjustment were significant with respect to parents' education level, household income and academic satisfaction. Variations in the initial status and growth rate of suicidal ideation were significantly associated with household income and family structure. The relationship between school-life adjustment and suicidal ideation showed a negative correlation in which the starting value of the former increased and that of the latter decreased and vice versa. Conclusion: The results confirmed that school-life adjustment and suicidal ideation varied according to students' general characteristics. In addition, school-life adjustment was negatively correlated with suicidal ideation, thereby highlighting students' ability to adjust as an important factor influencing their suicidal thinking.

  • This study was conducted to examine the self-efficacy and rejection sensitivity of nursing college students and their college life adjustment, as well as to identify the impact of self-efficacy and rejection sensitivity on college life adjustment. An online survey via URL was conducted on 154 enrolled students from nursing colleges nationwide. The collected data were analyzed using SPSS/WIN 23.0 statistical software for descriptive statistics, independent t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression analysis. The results of the study showed that the self-efficacy of the subjects was 3.80±0.63 points, rejection sensitivity was 2.67±0.83 points, and college life adjustment was 3.58±0.54 points. The factor influencing the college life adjustment among nursing college students was self-efficacy (β=.42, p<.001), while rejection sensitivity showed a significant negative correlation with adaptation to university life (r=-0.24, p=.003), but it was not a significant influencing factor. Therefore, it is necessary to develop and utilize various teaching methods and programs for psychological and social support to enhance self-efficacy in order to improve the adjustment of nursing college students to college life.
