Purpose : This study was conducted to provide basic data on the relationship between environmental factors causing stress in clinical practice institutions and stress levels of dental hygiene students. Methods : The research subjects totaled 207 and it was analyzed with structured questionnaires. The collected data were analyzed using an IBM SPSS ver. 20.0. Results : The environmental factors causing stress according to the status of clinical practice institutions was statistically and significantly different in the case of Busan practice areas (p<0.01), dental university hospitals (p<0.001), attendance times prior to 8am (p<0.001), quitting times that surpassed 8pm (p<0.01), and the number of dentists exceeding 4 (p<0.01). It was found to affect the stress level of students when individuals had to stand for a long period of time(p<0.001, ${\beta}=0.254$) and with the use of unfamiliar tools and equipment(p<0.05, ${\beta}=0.178$). Conclusions : As a result of the research conducted, it should be concluded that dental clinics should provide rest areas for individuals to focus on clinical practice. In addition, it is necessary to develop a systematic program that enables students to communicate with students at any time during the training period.

The purpose of this study is to forecast patient satisfaction and service value through the staged regression analysis of the relation between each factor and its satisfaction and service value, following the measurement of the quality of dental care service that patients recognize. And a self-administered survey was used for this study. The subjects of this survey were 394 outpatients of dental clinics located in K city in the period from Dec. 5, 2004 to Feb. 19, 2005, the questionnaire was composed of a total of 31 questions to measure the quality of overall dental care service(22 questions), the patient satisfaction(6 questions) and the service value(3 questions). The 7 points Likert scale ranging from "very poor"(1-point) to "very high"(7-point) was used for these questions The results of study could be summarized as follows: 1. The most useful index to predict patient satisfaction turned out to be "internal environment", followed by "treatment process and waiting time", "dentist", "external environment", and "dental hygienist". 2. The service value had a significant effect on the "internal environment", "dentist", "treatment process and waiting time". 3. The most useful index to predict the service value turned out to be "treatment process and waiting time", followed by "internal environment" and "dentist". Today, the quality of dental care service is becoming a prime concern since it is directly connected to a matter of survival of medical service organizations. Dental clinics desperately need patient-oriented marketing strategies in order to actively cope with changing medical environment. They also need to thoroughly examine possible measures to maximize the service value by establishing a variety of service strategies which can promote service quality that patients recognize.

Health effects of pesticide among vinylhouse workers in Sangjoo County, Kyungpook Province were assessed by measuring cholinesterase, glutathion reductase, and methemoglobin. Activities of cholinesterases among vinylhouse workers and general farmers were 3.89U and 3.98U in serum and 5.29U and 5.50U in red blood cells, respectively. While levels of methemoglobin between vinylhouse workers(0.16%) and general farmers(0.17%) were very similar, glutathione reductase among vinylhouse workers were 8% lower than that of general farmers. Inhibition of RBC cholinesterase among vinylhouse workers was two times greater than general farmers, suggesting a greater exposure of vinylhouse workers to the organophosphate pesticides. Methemoglobin level among vinylhouse workers with more than or equal to 10 vinylhouse units was 13% higher than that of the workers with less than 10 units. Vinylhouse workers using protective gears during pesticide spray showed higher level of reduced glutathione and lower level of methemoglobin, as compared to the non-users. This indicates that protective gears play an important role against pesticide exposure. Vinylhouse workers practicing good personal hygiene showed a higher level of reduced glutathione, as compared to those with poor personal hygiene, indicating that personal hygiene is also an important factor in reducing pesticide exposure. The present study represents a first attempt to analyze cholinesterase, methemoglobin and glutathione reductase activities among the vinylhouse workers. While neither vinylhouse workers nor general farmers showed abnormal findings among biochemical parameters used in the present study, increased level of methemoglobin and decrease of glutathione reductase activity among vinylhouse workers suggest that these workers have been subject to a higher exposure of pesticide than general farmers.

Objectives : The purpose of this study is to analyze the sterilizing effects of toothbrushes by administering bacteria into toothbrushes and reproducing the antibacterial effects using a microwave oven. Methods : The heads of four-row mid-strength toothbrushes were cut, put in a bacterial solution ($3{\times}10^9cells/ml$) for vortexing, and sterilized with microwaves for 0, 30, and 60 seconds. They were then moved into four tubes containing DW 10 ml and suspended in a vortex mixer for two minutes to separate bacteria from them. DW 9ml was added by 1ml of bacteria for dilution of $10{\sim}10^6$ times. It was then administered to the BHI agar plate by 0.1ml and cultured at $37^{\circ}C$ for 24 hours. Total number of bacteria adhered to a toothbrush was obtained by multiplying the number of colonies by the dilution factor. The experiment was done in the first, second, and third step, being repeated in a normal temperature drier ($23^{\circ}C$) after 5, 9 and 24 hours. Results : The results of the experiment revealed that the sterilizing effects were 95% or over. When toothbrushes were sterilized for 60 seconds, the number of colonies is about 11 after drying for 5 hours, 7 after drying for 9 hours and 2 after drying for 24 hours. The sterilizing effects reached 98% when the bacteria-administered toothbrush was sterilized for 1 minute after drying for 24 hours. Conclusions : The results demonstrated that toothbrush sterilizing by using microwave is a suitable way to prevent cross-contamination of toothbrushes by oral bacterial infection and thus easy to use at home. However, this study suggests that toothbrush sterilizing by using microwave should be limited within two times a week because the physical properties of toothbrush might be changed.

Objectives: The purpose of this study was to analyze the influence of job satisfaction on turnover intention in dental hygienists. Methods: A self-reported questionnaire was filled out by 169 dental hygienists in Gwangju from June 1 to December 31, 2014. Data analysis was performed with t-test, ANOVA and multiple regression analysis using SPSS WIN version 21.0 program. Results: By Likert 5 points scale, mean of job satisfaction was $3.08{\pm}0.35$ points, mean of personal relationship was $3.35{\pm}0.55$ points, and monthly compensation and promotion were $2.91{\pm}0.63$ points and mean of autonomy was $2.79{\pm}0.70$ points. Job satisfaction was the highest in those who were married and over 30 years old. Job satisfaction was highest in those who worked in the general hospitals and had longer career as a dental hygienist. Mean of the turnover intention was $3.31{\pm}0.81$ points. The factors of job satisfaction and turnover intention had the inverse correlation. The influencing factor of turnover intention(${\beta}=-0.327$) were monthly compensation, promotion, job satisfaction(${\beta}=-0.301$), and satisfaction for the location of the job(${\beta}=-0.157$). Conclusions: Turnover intention of dental hygienists is closely related to economic compensation, promotion, working department, and location of the job.
