  • Objectives: The purpose of the study is to investigate the relationship between safety and health activities of clinical dental hygienists. Methods: A self-reported questionnaire was completed by 208 dental hygienists in Seoul, Gyeonggido, and Incheon from May 9 to June 30, 2016. The study was approved by institutional review board (IRB). The questionnaire consisted of general characteristics of the subjects (9 items) and safety activities (15 items), and health activities (17 items) by Likert 5 point scale. Except two incomplete answers, data were analyzed using SPSS 22.0 program. Results: The mean of safety activities and health activities was 3.04 and 3.55, respectively. A significant difference was shown in staff safety, facility safety, environmental safety, infection control, and dental technique control (p<0.001). Conclusions: A significant association was shown in safety and health activities of clinical dental hygienists. It is necessary to promote the safety and health activities for the clinical dental hygienists.

  • The airborne concentrations of the welding fumes produced during $CO_2$ arcwelding process at shipbuilding, shiprepairing, container manufacturing and car accessary manufacturing industry were investigated. The effects how much reduced the welding fume were checked when the portable fan was used. The results were as follows; 1.The geometric mean of welding fume concentration in shipbuilding factory was $10.05mg/m^3$. This exposure concentration was higher than other 3 manufacturing industries at 95% confidence level. 2. The sampling filters for welding fume could be digested with acid within 1 hour by microwave oven. The recoveries for investigated metal elements were all over 95%. 3. The optimal wavelength could be selected for the simultaneous analysis of 8 metal elements by ICP(Inductively Coupled Plasma). 4. Noxious gases($O_1,NO_2$) produced during $CO_1$ gas arc welding process were detected that the concentration of ozone($O_1$) was less than 0.01 ppm and that of nitrogen dioxide($NO_2$) was 0.01-0.03 ppm. 5. The geometric mean of welding fume particle diameter was $1.26{\mu}m$ and geometric standard deviation was 1.51 for the counts when particle an analyzer(ELZONE) had been used. 6. When the portable fan had been used,the reduced percent of total welding fume for workers was about 47.8% when portable fan was applied to blow and 71.7% when to exhaust.

  • Objectives: The study was to promote patient safety by analyzing the effect of dental hygienist's perception of patient safety culture on infection control activities. Methods: The study is based on a survey of 377 dental hygienists in total working in dental settings. The questionnaire consisted of 119 questions, including 34 questions on perception of patient safety culture, and 85 questions on infection control activities. Hierarchical regression analysis was used to examine the relationship between the perception of patient safety culture and infection control activities. The data was analyzed using the SPSS version 20.0, and p<0.05 was adopted to decide on significance. Results: The longer dental hygienists have worked n the dental settings, the more active they become in infection control activities. Among the different types of dental care settings, general (university) hospitals had the largest number of infection control activities, followed by dental clinics, and network dental clinics, in descending order. The dental settings possessing a higher number of dental hygienists were found to conduct more infection control activities than other dental settings. In addition, it was found that when a dental setting adopts a patient safety policy across all the units in the hospital, more systems and procedures for patient safety tend to be established, and that stricter management response to error leads to improvement of infection control activities. Conclusions:In order to enhance infection control activities, infection control activity programs should develop and implement periodic reinforcement of infection control education. regular monitoring of infection control activities.
