Keeping good, talented people is one of the most significant factors in a company's success. HR analytics is an important area for applying big data analysis techniques to human resources. It provides organizational insight that enables effective management of employees, allowing management to reach their business goals quickly and efficiently. Job satisfaction and employee turnover analysis are the keys to HR analytics. Job review web services have been becoming popular. Because people exchange information about job satisfaction and turnover through these web services, useful information about HR Analytics is accumulated on the job review web sites. In this paper, we identified factors of employee retention by analyzing a Job Satisfaction/Retention group, and the factors of employee turnover by analyzing a Job Unsatisfaction/Turnover group. In order to do this, we first classified employees according to whether their self-reported job satisfaction or turnover was true. We collected and analyzed data from Jobplanet, a popular job review site. Through dominance analysis and LDA topic modeling, we found major factors, topics, and keywords of the classified groups by IT, service, and manufacturing domains. Our approach is a novel model to apply the analysis of reviews and text mining to the HR domain, and it will be practically helpful for setting new strategies that improve job satisfaction.

Purpose: This study examined the effect of hospitals' family-friendly management on married female nurses' retention intention. The focus was the mediating effects of the work-family interface (work-family conflict, work-family enrichment and work-family balance). Methods: This study was a cross-sectional study. The participants were 307 nurses working at five public and five private hospitals with more than 200 beds in Seoul. Data were collected using structured questionnaires from September 10 to September 17, 2018 and analyzed with SPSS 24.0. Data were analyzed using an independent t-test, a one-way ANOVA, Pearson's correlation coefficients, and multiple regression following the Baron and Kenny method and Sobel test for mediation. Results: There were significant correlations among family-friendly management, the work-family interface, and retention intention. Work-family conflict showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family enrichment showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family balance showed a partial mediating effect on the relationship between family-friendly management and retention intention. Conclusion: These findings indicate that both hospitals' family-friendly management and nurses' work-family interface are important factors associated with nurses' retention intention. Therefore, hospitals should actively implement family-friendly management for nurses and establish strategies to enhance nurses' work-family interface for effective human resource management.

High-performance liquid chromatography is suitable for getting thermodynamic information about solute-solvent interactions. We used a squalane impregnated $C_{18}$ phase as a presumably bulk-like stationary phase to secure a simple partition mechanism for solute retention in reversed phase liquid chromatographic system. We measured retention data of some selected solutes (benzene, toluene, ethylbenzene, propylbenzene, butylbenzene, phenol, benzylalcohol, phenethylalcohol, benzylacetone, acetophenone, benzonitrile, benzylcyanide) at 25, 30, 35, 40, 45, and 50 $^{\circ}C$ in 30/70, 40/60, 50/50, 60/40 and 70/30 (v/v%) acetonitrile/water eluents. The van't Hoff plots were nicely linear, thus we calculated dependable thermodynamic values such as enthalpies and entropies of solute transfer from the mobile phase to the stationary phase based on more than four retention measurements on different days (or weeks). We found that the cavity formation effect was the major factor in solute distribution between the mobile and stationary phases in the system studied here. Our data were com-pared with some relevant literature data.

Multivariate data analysis tools were used to improve the understanding of the wet end chemistry and white water system of the Papermill at NorskeCanada Crofton Division. Specifically, the analysis was aimed at identifying what variables were contributing to increased retention aid use and wet end instability. Several models were developed using data sets with up to 88 process variables and over 3000 observations. It was found that increased retention aid use was driven primarily by PCC and TMP usage as well as the addition of Alaskan White Spruce to the TMP furnish.

Objectives: Although dental hygienists are professional workers, their job retention is short. Therefore, in order to improve job retention, the relationship between professional identity and professional self-concept was analyzed. Methods: From January 1 to April 30, 2020, 155 dental hygienists were examined. For data analysis, multiple regression analysis was conducted to confirm the effects of professional identity and professional self-concept on job retention. Results: The dental hygienist's professional self-concept was significantly higher in the team manager than in the staff, but the professional identity was not significantly different. Dental hygienists' professional identity, professional self-concept, and job retention were all positively correlated (p<0.05). As a factor influencing dental hygienist's job retention, the self-concept of the profession had a significant effect, but the identity of the profession did not. Conclusions: Since the professional self-concept has a positive effect on maintaining the profession of dental hygienists, it is necessary to make efforts to improve the professional self-concept in order to increase the job retention.

Purpose: The purpose of this study is to examine the mediating effect of professional quality of life among hospital nurses in the effects of workplace bullying, social support and resilience on retention intention. Methods: A descriptive and cross-sectional study was conducted on 414 hospital nurses who worked for at least two months at a general hospital in the Seoul metropolitan area. The data were analyzed using IBM SPSS 23.0/AMOS 22.0 programs and employed reliability verification, descriptive statistics include frequency analysis, confirmatory factor analysis, structural equation modeling, and bootstrapping. Results: As a result of the study's structural modeling verification, workplace bullying had a negative effect, social support had a positive effect, resilience had a positive effect on professional quality of life, and professional quality of life had a positive effect on retention intention. Also, workplace bullying, social support, and resilience did not directly impact on retention intention. However, the professional quality of life had a complete mediating effect in the relationships between workplace bullying, social support, resilience and retention intention. The study results verified the mediating effect of professional quality of life affecting the retention intention. Conclusion: In order to improve professional quality of life and retention intention, strategies to prevent workplace bullying and promote social support and resilience are needed.
