Objectives: The purpose of this study was to examine how the dentist's servant leadership affects the happiness index of dental hygienists. Methods: The subjects were 221 dental hygienists that have been working at dental clinics or dental hospitals. The data were analyzed using SPSS Version 20.0 (IBM Co., Armonk, NY, USA). An independent t-test and one-way ANOVA analysis were conducted to examine the difference in the happiness index of dental hygienists according to general characteristics. The independent t-test was conducted to examine organizational culture and happiness index according to upper and lower group based on the mean score for servant leadership. Pearson's correlation analysis was used to examine the correlation among key factors. Multiple regression analysis was conducted to identify factors influencing the happiness index of dental hygienists. Results: According to the analysis, there was a statistically significant positive correlation between the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. However, a stewardship of the dentist's servant leadership factors was not found to have any correlation with the market culture. A multiple regression analysis was performed after including the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. Meanwhile, the stewardship and community-building effect of the dentist's servant leadership had a statistically significant effect on the happiness index of dental hygienists. Consequently, a higher servant leadership factor in dentists was correlated with a higher happiness index of dental hygienists. Conclusions:The findings show that the dentist's servant leadership affect the happiness index of dental hygienists. Therefore, effective intervention and education programs related to the dentist's servant leadership and sound organizational culture are necessary to enhance dental hygienists' happiness index. Additionally, a follow-up study will determine the causal relationship among the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists, considering organizational members and the environment of the dental clinics.

This study was conducted to examine the latent classes in social exclusion and to analyse empirically the effects on the economic instability of old age by this type. And it also sought to look at whether the influence of old age anxiety varies with the subjective class consciousness of the elderly. Using the 14th data from the Korea General Social Survey (KGSS) in 2016, 1,041 adult males and females aged 18 years old were analyzed at the time of the survey. T-test, potential layer analysis (LCA), and multinomantic analysis of potential groups were conducted using the STATA14 and MPLUS 7 statistical programs. Finally, multi-regression analysis was performed to identify the moderate effect and effects among variables. According to the research, the types of social exclusion were three groups, followed by social exclusion group (49.3%), Multi-dimensional exclusion group (30.9%), and active social participation group (19.7%). The social exclusion group has the lowest possibility of economic, employment, and health exclusion, but the exclusion of formal and informal social activities seem to prominent, and the multi-dimensional exclusion group is more than 50% likely to experience exclusion in all areas. Active social participation are characterized by very active participation in informal social activities. By conducting multinominal logistic regression, it was observed that the social exclusion group included more young people than other groups, and that the multi-dimensional exclusion group included many elderly women without spouses. Finally, multiple regression analysis showed that social exclusion type interacts with subjective class consciousness and affects economic anxiety of old age.

This study is to analyze change of connectivity between brain positions caused by relaxation through EEG coherence. EEG spectrum analysis method has been used to analyze brain activity when relaxation was experienced. However, the spectrum analysis method has a limit that could not observe interactive reaction between brain-functional positions. Therefore, coherence between positions was analyzed to observe connectivity between the measurement positions in this study. Through the method, the reaction of the central nervous system caused by the emotion change was observed. Twenty-four undergraduates of both genders(12 males and 12 females) were asked to close their eyes and listen to the sound. During experiment, EEG was measured at eight positions. The eight positions were F3, F4, T3, T4, P3, P4, O1, and O2 in accordance with International 10-20 system. The sounds with white noise and without were used for relaxation experience. Subjective emotion was measured to verify whether or not they felt relaxation. Subjective emotion of participants were analyzed by ANOVA method(Analysis of Variance). In the result, it was proved that relaxation was subjectively evoked when participants heard sound. Accordingly, it was proved that relaxation could be enhanced by the mixed white noise. EEG coherence between the measurement positions was analyzed. T-test was performed to find its significant difference between relaxation and not-relaxation. In the results of EEG coherence, connectivity with occipital lobes has been increased with relaxation, and connectivity with parietal lobes has been increased with non-relaxed state. Therefore, brain connectivity has shown different pattern between relaxed emotion and non-relaxed emotion.
