  • Objective: Despite known associations between negative body image and health declines in chronic pain patients, few studies have examined longitudinal associations between psychological stress and perceived hand deformities. This study examined whether psychological distress was associated with hand deformities 4 years later and if rural and urban adults differed in the association. Design: A community-based cohort study. Methods: Community dwelling adults (mean age=51.97, 52.3% women) in a rural (n=2968) and urban area (n=2784) provided demographic data at baseline and, in the 4-year follow-up, responded to questionnaires about psychological distress. Perceived hand deformities were assessed at the 8-year follow-up. Linear regression was conducted to examine the effects of psychological distress on hand deformities and moderation by residential areas. Results: The perceived hand deformities were more likely among those with severe psychological stress, hand osteoarthritis, or any chronic disease condition (p<0.01) but less likely among those with younger age, higher education, or income (p<0.01). The regression results showed that psychological distress predicted more perceived hand deformities 4 years later even after adjusting for demographic and health covariates (p<0.01). The residential areas did not significantly moderate the association between distress and hand deformities. Conclusions: This study suggected that psychological distress may trigger later perception of hand deformities in both urband and rural adults. The findings indicate that stress management interventions that are customizable to regional contexts may be effective at preventing negative body image related health problems of community-dewelling adults.

  • In recent years, the use of underground spaces becomes more frequent and the demands for urban tunnels are rapidly increasing. The urban tunnels constructed in the ground with a shallow and soft cover might be deformed in various forms on the face, which would lead, the tunnels to behavior 3-dimensionally, which may have a great impact on the longitudinal load transfer. The tunnel face might deform in various forms depending on the construction method, overburden and the heterogeneity of the ground. And accordingly, the type and size of the distribution of the load transferred to the ground adjacent to the tunnel face as well as the form of the loosened ground may appear in various ways depending on the deformation form of the tunnel face. Therefore, in this study was conducted model tests by idealizing the deformation behavior of the tunnel face, that were constant deformation, the maximum deformation on the top and the maximum deformation on the bottom. And the test results were analyzed focusing on the deformation of the face and the longitudinal load transfer at the ground above the tunnel. As results, it turned out that the size and the distribution type of the load, which was transferred to the tunnel as well as the earth pressure on the face were affected by the deformation type of the face. The largest load was transferred to the tunnel when the deformation was in a constant form. Less load was transferred when the maximum deformation on the bottom, and the least load was transferred when the maximum deformation on the top. In addition, it turned out that, if the cover became more shallow, a longitudinal load transfer in the tunnel would limited to the region close to the face; however, if the cover became higher than a certain value, the area of the load transfer would become wider.

  • Although many studies have been performed for the structural details of orthotropic steel deck, most of them were focused on the trough rib of standard type, but not for orthotropic steel deck with longitudinal rib of open section used at beginning of the deck. In order to investigate the cause of fatigue crack for orthotropic steel deck bridge serviced 31 years with longitudinal rib of open section, in this study, the behavior characteristics of target structural details were analyzed based on measurement data under real traffic condition. Also the typical loading truck passing the target bridges was estimated with the structural analysis detailed, and the stresses and deformation patterns of target structural details were analyzed by performing the detailed structural analysis. Based upon the analysis, retrofitting methods of the fatigue crack were suggested and its validation was examined. From this study, it was clarified that fatigue crack of longitudinal rib with open section were affected with the stress increment by shear deformation in the rib and the occurrence of alternative stress due to moving vehicle. In addition, it was known that it is important to perform fatigue design reflected the local behavior of the structural details.

  • This study is a longitudinal analysis of the life satisfaction of Generation X and Generation Y, with different historical backgrounds, growth backgrounds, values, and lifestyles, using data from the Korean Welfare Panel(KOWEPS). The research data is from the KOWEPS 1st year(2006) to 14th year(2019), out of 27,301 people, who conducted life satisfaction from the latest 12th to 14th year, and the responses were properly answered data from 3 years of 2,492 were used. As a result of the study, the higher the life satisfaction of both Generation X and Generation Y, the more the life satisfaction slowly increases at a slower rate as time passes. In addition, in terms of life satisfaction and rate of change, the initial value of life satisfaction was higher as the living satisfaction increased in both Generation X and Generation Y, but in the case of Generation X, the higher living satisfaction, the lower the rate of change in life satisfaction for 3 years by .327, in the case of Generation Y, the rate of change in life satisfaction was not affected. Finally, in the model of this study, a partial mediation of health condition was established between living satisfaction and life satisfaction tendency. Living satisfaction was analyzed to have a direct effect on life satisfaction and at the same time indirectly with a health condition as a parameter.

  • The purpose of this research was to investigate the effect of the achievement goal orientation on college students' life satisfaction and sense of the belonging. This study used the analysis of the latent growth model to comprehend the slope of the 3 years longitudinal data. The result was that mastery approach and mastery avoidance affected the initial value of college life satisfaction, but not its slope as the time of 3 years went. On the other hand, performance approach was the opposite of mastery approach and mastery avoidance to college students' life satisfaction. Performance avoidance did not have an influence on both the initial value and the slope of college students' life satisfaction. The effect of the achievement goal orientation to the sense of belonging was also explored and its result was that mastery approach and mastery avoidance affected the initial value of the sense of belonging. However, it was different that performance approach did not influence the slope of the sense of belonging.

  • This study investigated relationships between primary caregivers' life satisfaction and abuse mediated by children's life satisfaction. We included term panel data for 3 years (2013-2015) from the 4th year to the 6th year of 2,067 children in the first grade of elementary school of the Korean Youth and Youth Panel(KCYPS)(2015); in addition, three years' longitudinal panel data (2013-2015) were analyzed utilizing SPSS 18.0 and AMOS 22.0 to measure Latent Growth Model(LGM) term relationships between variables. Analysis results were as follows. First, the life satisfaction of the primary caregiver, the life satisfaction of the child, and abuse gradually decreased from the fourth grade to the sixth grade. Second, the initial status of primary caregivers' life satisfaction influenced the initial status of the children's life satisfaction, and the initial status and change in the abuse rate. Third, the rate of change of life satisfaction of the primary caregiver did not have a significant effect on the change in the abuse rate and the rate of change of life satisfaction of the child. The initial value of the life satisfaction of the child played a partial mediating role in the relationship between the initial value of the life satisfaction of the primary caregiver, initial value of the abuse, and abuse change rate. The results suggest that a program to improve the life satisfaction of the 4th grade elementary school should be developed and applied.

  • This study examined the relationship between the demographic profiles of 260 staff nurses in the SPC Health Care Ministry Hospitals and their Transcultural Self-Efficacy (TSE) level on the Cognitive, Practical and Affective dimensions. To obtain the result, among the nine (9) demographic profile items, three (3) common positive predictors were considered, namely, 1) Educational attainment level; 2) Age; and 3) Willingness to work abroad in all three dimensions. While in the Practical and Affective dimensions, the number of years employed were a common negative predictor and in the Affective dimension, Gender of participants was added as the positive predictor. Therefore, there are some significant demographic characteristics of respondents influence to the transcultural self-efficacy. Further, based on the results of this diagnostic study, the researcher designed the One (1) year Cultural Competence Training Program for staff nurses. For future research, the researcher recommended to conduct a further study that will evaluate the effectiveness of the educational intervention by approaching a longitudinal study form administering the test and retest of TSET.

  • Purpose: This study was conducted to evaluate cognitive ability in preschoolers born prematurely and to investigate related factors. Methods: A prospective, longitudinal study was conducted with 64 children at 5-6 years of corrected age (CA) (second follow-up) among 76 children who had been assessed at 2.0~3.5 years of CA (first follow-up) from a sample of 343 preterm infants born from 2008 to 2010. To evaluate each child's cognitive ability, during a home visit, we used the Kaufman Assessment Battery for Children-II (KABC-II) at the second follow-up. To explore factors related to cognitive ability, we measured children's hemoglobin level at the second follow-up and used the data collected in our previous study, including the Bayley Scale of Infant Development-II (BSID-II) at the first follow-up. Results: The mean total KABC-II quotient was $117.0{\pm}14.4$. The 5-minute Apgar score (${\beta}=.29$, p=.006), hemoglobin level (${\beta}=.22$, p=.032), and the mental development index quotient of the BSID-II (${\beta}=.51$, p<.001) were statistically significant predictors of the KABC-II quotient in multiple linear regression analysis. Conclusion: The cognitive function of young children born prematurely was influenced by early neurodevelopment and factors reflecting their health status, such as anemia and a low 5-minute Apgar score.

  • Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

  • Purpose - This study analyzes the intertemporal patterns in personnel decisions made between a supervisor and a subordinate to understand potential supervisor bias in the decisions. A correlation between the current and the most recent personnel decisions made for a subordinate by a current supervisor captures certain relationship-embedded and time-invariant factors in effect. The characteristics speak to the nature of a supervisor bias arising from a relationship, or favoritism. Design/methodology/approach - This study manually collects the executive profile data from annual reports of key Samsung Group affiliates and compile a longitudinal sample of 3,675 executive-years. It mainly explores the logistic regression analysis. Findings - The study finds that a supervisor' previous promotion award to a subordinate does not improve but decreases the likelihood of promotions in ensuing years, suggesting the containment of favoritism; and that the time since the last promotion award to a subordinate by the current supervisor increases the likelihood of both promotions and dismissals of the subordinate. Research implications or Originality - The findings are generally consistent with the theory suggesting that incentive schemes that align interests between an individual and an organization will contain the form of a supervisor bias.
