This study aims to analyze the impact of names on stress and self-esteem, comparing before and after renaming. A survey was published and conducted on a renaming club website for the period from 1 April 2013 to 31 May and there were 161 participants. The invitation to survey was limited to members who had changed their names at least six months before the survey and the impact was measured by comparing before and after the first renaming. For the analysis of the data, frequency analysis, t-test, one-way ANOVA and correlation analysis were performed. As a result, the level of stress caused by one's name was lowered after renaming, and one's self-esteem significantly went up compared to before renaming. Therefore, the stress from one's name is believed to affect one's self-esteem, and the study shows that there is a negative correlation as the lower the stress from one's name becomes, the higher one's self-esteem goes up. Therefore, this study is considered to be able to contribute to reducing stress caused by names, as it has proved that the self-esteem increases and the level of stress is lowered after renaming.

Airframe structure development of the 35 kg class 'Disaster and Public Safety Multicopter' UAV is described in this paper. To reduce the airframe weight, T-700 grade CFRP composite material was used, and the fuselage was designed with the semi-monocoque structure and plate installed with the control and communication devices designed in a sandwich structure. The specimen tests for the laminated plate and pipe were conducted to verify the strength and stiffness of the designed parts. The stacking sequence of composite materials was determined by the static strength and vibration analysis, and landing gear strut was designed by the nonlinear analysis with decent speed and ground clearance requirements. The static strength test was performed to evaluate the structural integrity and to verify the landing gear behavior.

The purpose of this study was to investigate the effects of stress factors on fatigue and depression of aesthetician. The subjects of this study were 133 Aesthetician in Busan Metropolitan City. Analysis was done by frequency analysis, t-test, one-way ANOVA and regression analysis. The results of this study are as follows. First, the aesthetician showed an average 2.57 of job stress. Second, the aesthetician showed an average 2.45 of socio-psychological stress. Third, the aesthetician showed an average fatigue(4.16) and depression(1.54). Therefore, in order to reduce the duties and socio-psychological stress of the aesthetician, fatigue and depression are reduced through regularization of the employees, adjustment of legal working hours, and establishment of similar paying system. Finally, it is necessary to lower the turnover rate of the aesthetician and increase the job satisfaction.

The purpose of this study is to determine the impact of physical activity on relieving job burnout among teachers in Korea. To examine this impact, 527 Korean teachers were used in the data analysis. An exploratory factor analysis and internal consistency analysis were employed to verify the validity and reliability of the Maslach Burnout Inventory (MBI-ES), and a t-test and one-way ANOVA were conducted to find the mean differences according to gender, school level, and length of teaching experience. The impact between factors was also verified through correlation and regression analyses. The results of the analyses showed that first, female teachers and teachers with less teaching experience had higher degree of burnout and fewer physical activities compared to male teachers and teachers with longer teaching experience, respectively. Second, teachers' level of moderate-to-vigorous physical activity (MVPA) was negatively correlated with burnout factors. Third, teachers' vigorous physical activity negatively affected depersonalization factors while teachers' sedentary activity positively affected depersonalization factors.

The single and the married couples elderly are rapidly increasing in the next twenty years. Due to the size of these group, their level of living, life satisfaction, income and medical security and welfare services utilization have been a social issue in Korea. For these reasons, the purpose of this study was to analyze the determinants of welfare services utilization by the single and the married couples elderly.

Data were collected from a survey of 2,716. The results showed that the elderly single women had the lowest level of income and health, the elderly single men needed the help about the emotional support for improvement of family and social relations.

Background: The sagittal alignment of the spine and pelvis is not only closely related to the overall posture of the body but also to the evaluation and treatment of spine disease. In the last few years, the EOS imaging system, a new low-dose radiation X-ray device, became available for sagittal alignment assessment. However, there has been little research on the reliability of EOS. The purpose of this study was to evaluate the intrarater and interrater reliability of EOS for the sagittal alignment assessment of the spine and pelvis. Methods: Records of 46 patients were selected from the EOS recording system between November 2016 and April 2017. The exclusion criteria were congenital spinal anomaly and deformity, and previous history of spine and pelvis operation. Sagittal parameters of the spine and pelvis were measured by three examiners three times each using both manual and EOS methods. Means comparison t-test, Pearson bivariate correlation analysis, and reliability analysis by intraclass correlation coefficients (ICCs) for intrarater and interrater reliability were performed using R package "irr." Results: We found excellent intrarater and interrater reliability of EOS measurements. For intrarater reliability, the ICC ranged from 0.898 to 0.982. For interrater reliability, the ICC ranged from 0.794 to 0.837. We used a paired t-test to compare the values measured by manual and EOS methods: there was no statistically significant difference between the two methods. Correlation analysis also showed a statistically significant positive correlation. Conclusions: EOS showed excellent reliability for assessment of the sagittal alignment of the spine and pelvis.

The use of smartphone improves convenience and efficiency in modern people's lives but threatens the mental health of individuals by manifesting an addiction phenomenon that is difficult for everyday life without a smartphone. In particular, it is suggested that the effects of the smartphone addiction of firefighters who have a high level of job stress due to work environment exposed to disaster and fire have a very negative effect on their personal well-being and job performance. Therefore, the analysis of the relationship between firefighters' smartphone addiction and stress will be helpful in examining the problems of stress management. This study analyzed the relationship and influence between smartphone addiction and stress of firefighters. Total study subjects were 230 and SPSS 20.0 was used. Statistical methods are group analysis (t-test and ANOVA) and multiple regression analysis. The results of this study show that firefighters' household type and monthly income have a significant effect on stress. Of the sub-factors of smartphone addiction, withdrawal experience has a statistically significant effect on stress. The results of the study will provide empirical data on the smartphone addiction of fire service employees.
