The purpose of this study was to investigate the convergence relationship between the clinical practice stress and professional identity of 171 dental hygiene students from 3 university in Jeollanam-do area. The data were analyzed using SPSS WIN 18.0 program. Professional identity was negatively correlated with clinical practice training environment(r=-0.352, p<0.01), clinical practice work burden(r=-0.185, p<0.05) and conflicts with patients(r=-0.181, p<0.05). The convergence factors influencing professional identity were clinical practice training environment(${\beta}=-0.261$), aptitude(${\beta}=0.238$), advice from others(${\beta}=-0.186$) and clinical practice unsatisfied(${\beta}=-0.176$). The regression model explained 23.7% of professional identity. Therefore, it is necessary to develop a program for the smooth labor supply by understanding the relationship between clinical practice stress and professional identity in dental hygiene students.

Background: The leaves of Perilla frutescens, commonly called perilla and used for food in Korea, contain components with a variety of biological effects and potential therapeutic applications. The purpose of this study was to identify the components of 70% ethanol extracted Perilla frutescens (EEPF) and determine its inhibitory effects on oral microbial activity and production of nitric oxide (NO) and prostaglandin E2 (PGE2) in lipopolysaccharides (LPS)-stimulated Raw264.7 macrophages, consequently, to confirm the possibility of using EEPF as a functional component for improving the oral environment and preventing inflammation. Methods: One kg of P. frutescens leaves was extracted with 70% ethanol and dried at -70℃. EEPF was analyzed using high-performance liquid chromatography analysis, and antimicrobial activity against oral microorganisms was revealed using the disk diffusion test. Cell viability was elucidated using a methylthiazolydiphenyl-tetrazolium bromide assay, and the effect of EEPF on LPS-induced morphological variation was confirmed through microscopic observation. The effect of EEPF on LPS-induced production of pro-inflammatory mediators, NO and PGE2 was confirmed by the NO assay and PGE2 enzyme-linked immunosorbent assay. Results: The main component of EEPF was rosemarinic acid, and EEPF showed weak anti-bacterial and anti-fungal effects against microorganisms living in the oral cavity. EEPF did not show toxicity to Raw264.7 macrophages and had inhibitory effects on the morphological variations and production of pro-inflammatory mediators, NO and PGE2 in LPS-stimulated Raw264.7 macrophages. Conclusion: EEPF can be used as a functional material for improving the oral environment through the control of oral microorganisms and for modulating inflammation by inhibiting the production of inflammatory mediators.
