Dental hygienists students are required to be able to interact and maintain relationships with dentists and patients. Therefore, the purpose of this study was to identify the relations affecting interpersonal competence of some dental hygiene students, and to provide the necessary data for nurturing competent dental hygienists. The survey was conducted on 293 dental hygiene students in M university. The level of significance was .05 and the statistical program was SPSS win 25.0. As a result of interpersonal competence according to general characteristics and interpersonal characteristics, significant results were found in the degree of human relations and new environmental adaptability. As a result of correlation analysis between subvariables of interpersonal competence, all showed significant positive correlation. Factors affecting interpersonal competence showed significant positive effects on the degree of human relationship(p=.019) and the new environmental adaptability(p=.001). Interpersonal competence are important in the clinic. Therefore, a convergent analysis of the factors influencing is required.

Considering the complex structure and high volatility in the shipping market, it is important to investigate the connectedness amongst influencing factors. This study explores the dynamic relationship between supply-demand factors and shipping freight indices. We choose Capesize and Panamax in the bulk carrier market and use quarterly data of GDP, world fleet, BCI, and BPI from 1999 to 2021. Applying the wavelet analysis and wavelet Granger causality test, the simultaneous examination of co-movement and causality between two factors and the shipping market in both the time and frequency domains is achieved. We find that co-movement and causality vary across time and frequencies, thereby existing dynamic relationships between variables. Second, compared to multiple coherencies using demand and supply factors together, partial coherencies indicate noticeable causalities. It implies that analyzing demand and supply factors separately is essential. Finally, shipping freight indices show a high correlation with the demand factor in a good market and with the supply factor in a bad market. Generally, GDP positively leads shipping freights in the recovery phase while the world fleet negatively leads shipping freights in the downturn. The research is meaningful in that the rarely-applied wavelet analysis is adopted in the shipping market and that it gives a reasonable ground to explain the role of supply and/or demand factors in different phases of the market cycle.

The purpose of this study was to explore the effects of adolescent's self-esteem and psychological separation from parents on their interpersonal competence. The study sample consisted of 625 high school students in Seoul, Korea who completed a self-administered questionnaire. The data were analyzed using t-tests, correlations, and hierarchical regression analysis. The main findings were as follows. First, the level of interpersonal competence differed by gender. Second, a higher level of interpersonal competence among adolescents was significantly correlated with a higher level of adolescent's positive self-esteem, lower level of adolescent's negative self-esteem, and higher level of psychological separation. Third, positive self-esteem was the most significant predictor of adolescents' interpersonal competence, followed by parent's regulation. Overall, the results suggest that self-esteem is very important to promote positive interpersonal competence among adolescents. Therefore, programs to address such issues are strongly needed.

In this paper, we propose a novel analysis method and its algorithms to perform the betweenness centrality measurements on a valued and directed workflow-supported social network. The conventional workflow-supported social network model is to represent the existences of task transferring relationships among their performers by using a binary social network. However, it is necessary to consider not only the existences of task transferring relationships but also their quantities and directions in order to obtain much more effective and sophisticated analysis results. In conclusion, this paper newly defines a concept of valued and directed workflow-supported social network, and its betweenness centrality analysis method and algorithms. Especially, to verify the proposed method and algorithms, we try to apply the conventional method and the proposed method to an example workflow model respectively, and compare their betweenness centrality analysis results.

In this study, it is analyzed how large scale climate variation has an effect on climate systems over Korea using correlation analysis between climate indices and Intrinsic Mode Functions (IMFs) of precipitation and temperature. For this purpose, the estimated IMFs of precipitation and temperature from the accompanying paper were used. Furthermore, cross correlation coefficients and lag time between climate indices and IMFs were calculated considering periodicities and tendencies. As results, more accurate correlation coefficients were obtained compared with those between climate indices and raw precipitation and temperature data. We found that the Korean climate is closely related with climate variations of $El-Ni{\tilde{n}}o$ in terms of periodicity and its tendency is followed with increasing sea surface temperature due to climate change.

We identified the mediating role of interpersonal issues in the relationship between adult attachment type and emotional expression ambivalence. The subjects of the study were 327 emotional workers who lived in five cities. As the scale, ECR-R, AEQ-K, and IIP were used. Sobel verification was performed after multiple regression analysis. The results show that the interpersonal problem partially mediates between the attachment and emotional expression ambivalence. This suggests that the characteristics of interpersonal relationships affect emotional emotions in forming close attachment relationships of emotional workers. Subsequent research will expand the scope of research by supplementing the shortcomings of existing research.
