This qualitative case study focuses on five small and medium-sized enterprises which have put family-friendly management into successful practice. Through in-depth unstructured interviews with five human resources managers and ten employees, we describe each firm's approach to work-life balance including working hour reductions, breaks, work flexibility, and parental leave to build an overall picture. We also discuss the four key factors of the CEO's role; democratic communication between all staff, the usefulness of family-friendly certification as a starting point; and governmental support for promoting work-life balance at small and medium-sized enterprises. Finally, we suggest three political implications of governmental support, namely CEO education, changing the criteria of family-friendly certification to redefine working hours and work flexibility, and incentives specifically for small to medium-sized enterprises.

Objectives: This study was performed to evaluate the analytical method for PAH metabolites in human urine using enzyme hydrolysis and solid-phase extraction coupled with LC-(ESI)-MS/MS technique. Methods: We employed HPLC tandem mass spectrometry techniques with appropriate pre-treatment for analysis of 16 OH-PAHs in human urine. Samples were hydrolysis by ${\beta}$-flucuronidase/Aryl sulfatase, and target compounds were extracted by solid-phase extraction with a strata-x cartridge. Cross-validation was performed between Eulji University and Green Cross laboratories with 200 human urine samples. Results: The accuracies were between 90.3% and 118.8%, and precisions (relative standard deviations) were lower than 10%. The linearity obtained was satisfying for the 16 OH-PAH compounds, with a coefficient of determination ($r^2$) higher than 0.99. The results of cross-validation at the two organizations were compared by ICC (interclass correlation coefficient) values. The cross-validation results were excellent or good for all compounds. Conclusion: An analytical method was validated for low nanogram levels of 16 OH-PAHs in human urine. Also, satisfying results were obtained for method validation such as accuracy, precision and ICC of cross-validation.
