Objectives: This study aims to serve as basic data for improving human resource management and the quality of work at dental hospitals and clinics by examining the relationship among clinical dental hygienists' emotional labor, job stress, and turnover intention. Methods: A self-reported questionnaire was completed by 220 dental hygienists in hospitals and clinics from March 11 to April 26, 2019. Data were analyzed using SPSS 20.0. For participants' burnout, job stress, emotional labor, and turnover intention based on general and occupational characteristics were analyzed using a t-test and one-way ANOVA. After performing a one-way ANOVA, a Duncan test was performed for mean comparison. Pearson's correlation analysis was conducted to determine correlations between variables, and stepwise multiple regression was performed to examine the factors that affect burnout. Results: Clinical dental hygienists' mean burnout was 3.05 points, and the factors that affect such burnout were turnover intention, job stress, and emotional labor. Burnout was higher when job satisfaction was low, turnover intention was low, and emotional labor was high, with a 29.3% explanatory power. Conclusions: For effective human resource management of dental hygienists, it is necessary to develop and implement programs that can reduce emotional labor and burnout.
Purpose: This study was to identify the stages of change in smoking cessation behavior and factors associated with the stages of smoking cessation behavior according to the trans-theoretical model. Methods: The subjects were 154 industrial workers working at H Industry in N City, Chonnam Province who were currently smoking and had smoked in the past. Data were analyzed by descriptive statistics, ANOVA, and Duncan's multiple comparison test using SAS Version 10.0. Results: The subjects were distributed among the stages of change in smoking cessation behavior: there were 28 subjects (18.2%) in the precontemplation stage, 71 (46.1%) in the contemplation stage, 21 (13.6%) in the preparation stage, 8 (5.2%) in the action stage, and 26 (16.9%) in the maintenance stage. The amount of smoking per day, self-efficacy, and advantages (pros) of smoking were significantly associated with the stage of change in smoking cessation behavior. Conclusion: This study suggested that the stage of change in smoking cessation behavior of the subject should be identified prior to the application of intervention programs, nursing intervention strategies should be considered to reduce the amount of smoking per day, and the disadvantages of smoking should be perceived.

Purpose: The purpose of this study was to compare the attitude of physicians and nurses toward family presence during cardiopulmonary resuscitation (CPR). Methods: 100 physicians and 100 nurses from five hospitals with than 500 beds in B city were surveyed using a Family Presence During Resuscitation (FPDR) Inventory. The data were analyzed by t-test, ANOVA and Duncan's multiple range test using SPSS/WIN 19.0 version. Results: Nurses showed more positive attitudes toward family presence during CPR but reported more concerns about the problem of confidentiality, arguing with family members, and emotional distress of family members than physicians did. Conclusion: On the basis of results from this study, we recommend that educational program be developed within the hospitals to change the negative perception of health care providers for the family presence during CPR.
The purpose of present study was to evaluate the polymerization shrinkage stress and cuspal deflection in maxillary premolars resulting from polymerization shrinkage of composites and compomers. Composites and compomers which were used in this study were as follows: Dyract AP, Z100, Surefil. Pyramid, Synergy Compact, Heliomolar, Heliomolar HB, and Compoglass F. For measuring of polymerization shrinkage stress, Stress measuring machine (R&B, Daejon, Korea) was used. One-way ANOVA analysis with Duncan's multiple comparison test were used to determine significant differences between the materials. For measuring of cuspal deflection of tooth, MOD cavities were prepared in 10 extracted maxillary premolars. And reduction of intercuspal distance was measured by strain measuring machine (R&B, Daejon, Korea) One-way ANOVA analysis with Turkey test were used to determine significant differences between the materials. Polymerization shrinkage stress is $\mathbb{\ulcorner}$Heliomolar, Z100, Pyramid < Synergy Compact Compoglass F < Dyract AP < Heliomolr HB, surefil$\mathbb{\lrcorner}$ (P < 0.05). And cuspal delfelction is $\mathbb{\ulcorner}$Z100, Heliomolar, Heliomolar HB, Synergy Compact Surefil. < Compoglass F < Pyramid, Dyract AP$\mathbb{\lrcorner}$ (P < 0.05). Measurements of ploymerization shrinkage stress and those of cuspal deflection of the teeth was different. There is no correlation between polymerization shrinkage stress and cuspal deflection of the teeth(p > 0.05).
Objectives: The purpose of the study is to examine the correlation and influencing factors among ethics position, self-esteem, and perception of patient medical information protection in the dental hygiene students. Methods: This is a cross sectional study using the structured questionnaire. A self-reported questionnaire was completed by 202 dental hygiene students using the stratified sampling method from September 1 to November 1, 2013. The questionnaire was modified and complemented from Ethics Position Questionnaire (EPQ). The questionnaire included EPQ, self-esteem, and perception of patient medical information protection. Data were analyzed by independent t-test, one way ANOVA, Duncan's multiple comparison analysis, Pearson's correlation analysis, and stepwise multiple regression analysis using IBM SPSS Statistics 21.0 program. Results: There was a positive correlation among all the variable including idealism position, self-esteem, and perception of patient medical information protection, The factors influencing on the perception of patient medical information protection were idealism position (${\beta}=0.271$, p<0.001) and self-esteem (${\beta}=0.248$, p<0.001). The corrected explanation power of the model was 15.1%. Conclusions: As the idealism position and self-esteem become higher, the perception of patient medical information protection gets higher. Therefore, this study suggests that it is needed to develop and vitalize implement the appropriate programs enhancing ethics consciousness, proper position, and self-esteem in the dental hygiene students receiving the education for their professionalism in the dental hygiene curricula.
The purpose of this study was to evaluate microleakage of six current dentin bonding systems. In this in vitro study, class V cavities were prepared on buccal and lingual surfaces of thirty extracted human molars. Each margin was on enamel and dentin/cementum. Experimental teeth were randomly divided into six groups of 5 each. Group 1 : Scotchbond Multi-Purpose; Group 2 : Single Bond; Group 3 : Prime&Bond NT ; Group 4 : Clearfil Liner Bond 2 ; Group 5 : MAC Bond II ; Group 6 : One-up Bond F. The bonding agent and composite resin were applied to class V cavities according to manufacturer's directions. After thermocycling, the specimens were immersed in 0.5% basic fuchsin dye solution for 6 hours and sectioned longitudinally through the center of the restoration with a low speed diamond saw. The degree of microleakage was measured as the extent of dye penetration under the stereomicroscope at $\times$20. The data were analyzed using one way ANOVA. When significant differences found. multiple comparisons were made using Duncan's Multiple Range Test. The results of this study were as follows: 1. In all groups, leakage value seen at the enamel margin was significantly lower than that seen at the dentin margin(P<0.001). 2. At the enamel margin, none of the dentin bonding systems used in this study showed statistically significant difference in leakage values(P<0.05). 3. At the cementum margin, group 3 showed the highest leakage value, and others were decreased as group 5, 6, 4 in that order, and group 1, 2 showed the lowest leakage value. There was statistically significant difference between group 3 and the other groups except for group 5(P<0.05).

purpose: This study was to evaluate the shear bond strength of Lithium Disilicate Glass-Ceramic by removable method of temporary cement on the abutment tooth. Material and Method: Sixty molar teeth of human with the occlusal surface up were mounted in acrylic resin blocks. The 45 specimens were prepared to exposure dentin by diamond bur and the eugenol-containing temporary cement($Cavitec^{TM}$ ($KERR^{(R)}$, U.S.A)was applied to the dentin surfaces. After initial removal of the cement with a dental explorer, the specimens were divided into 4 groups of 15 specimens each. The dentin surfaces of the specimens were treated by rotary instrument with as follow pastes: $Zircate^{(R)}$ prophy paste(Dentsply, U.S.A), Radent Prophy Paste(Pascal company,inc. U.S.A), and Dental pumice(Wip mix corporation,U.S.A). An adhesive resin luting agent(Variolink $II^{(R)}$, Ivoclar Vivadent, Leichtenstein) including Monobond-S and $Excite^{(R)}$ was applied to all specimens. The ceramic specimens were made with an A1 ingot of IPS Empress $II^{(R)}$ (Ivoclar Vivadent, Leichtenstein). After the specimens were stored in distilled water for 48hr, the shear bond strength(MPa) was measured by a Universal testing machine(Zwick 145641, Zwick, Germany) at a 1mm/min cross-head speed. The data were statistically analyzed by one-way ANOVA and Duncan's multiple range test. Results: In all group, there were no significant differences in comparison with the control group(p>0.05). The pattern of most failure showed the mixed type of cohesive and adhesive failure. Conclusion: Resin bond strength of IPS Empress $II^{(R)}$ was not affected by removal method of the temporary cement.

The purpose of this study is to analyze characteristics of water quality factor scientifically and develop the multiple regression model predicting dissolved oxygen to save periodic replacement costs for dissolved oxygen sensor. Correlation analysis using the environmental data obtained from 2 different land-based fish farms of the Geogeum-do, Geheung-gun coastal area during the periods from November 2008 to January 2009 shows that water temperature was negatively correlated with dissolved oxygen and pH butpH was positively correlated with salinity and dissolved oxygen. The information of Keumho fish farm in 2009 is presented by the tables which are monthly statistics of water quality factors and seasonable difference by the Duncan's post-test. Also we developed multiple regression model predicting dissolved oxygen, the usefulness of which was verified by the comparison graph between estimates and actual observations. The developed regression model shows that seawater temperature and salinity give negative affect to dissolved oxygen while pH gives positive affect to it. Lastly the seawater temperature has much higher explanatory power than pH factor.
The purpose of this study was to assess the effects of restorative materials on the marginal leakage of wedge-shaped class V cavity. The study was performed in vitro in 25 defect-free permanent, extracted teeth. Wedge-shaped class V cavities were prepared and then the teeth were randomly selected and restored according to the following. Group A : restoration with Tetric Ceram(composite resin) Group B : restoration with Tetric flow(flowable resin) Group C : restoration with Compoglass after acid etching(compomer) Group D : restoration with Compoglass(compomer) Group E : restoration with Fuji II LC improved(resin-modified GIC) After thermocycling, the specimens were immersed in 5% basic fuchsin solution for 6 hours and sectioned longitudinally through the center of the restoration. The degree of marginal leakage was measured as the extent of dye penetration under the stereomicroscope. The data were analysed using one-way ANOVA. When significant differences found, multiple comparisons were made using Duncan's Multiple Range Test. The results were as follows: 1. The occlusal margins of all groups except for Fuji II LC improved showed lesser leakage than gingival margins and there was statistically significant difference(p<0.05). 2. At the occlusal margins, group A, B showed same marginal leakage scores, and others were decreased as group C, D, E in that order. There were statistically significant difference between group A, Band group D, E, group C and group E(p<0.05). 3. At the gingival margins, group B, C showed same marginal leakage scores, and others were decreased as group A, D, E in that order. But there was statistically significant difference between group B, C and group E(p<0.05). 4. In the Compoglass restoration, acid-etching technique was beneficial for marginal sealing ability at all of margins. But there was no statistically significant difference (p>0.05). In the restorations for wedge-shaped class V cavities, resin restoration with acid etching technique is recommended.
The purpose of the study was to examine health status and mini nutritional assessment (MNA) according to self-esteem status of elderly in care hospital. The survey was carried out from $13^{th}$ to $31^{st}$ of September, 2014 in five care hospitals. Analysis was performed for 226 subjects. Evaluation criteria included demographics, clinical status, MNA, health-related quality of life (EQ-5D) and self-esteem. The SE I, SE II and SE III groups were divided by self-esteem scores. Data were analyzed one-way ANOVA, Duncan' multiple range test and Pearson's correlation using SPSS 15.0. Education level, religion, dental condition and medical endurance type were significantly different in all groups. Many elderly people were normal BMI ($20.94{\sim}21.67kg/m^2$). Self-esteem significantly increased in order of SE I, SE II and SE III. Mobility, usual activity and anxiety or depression were significantly different in all groups, and EQ-5D of SE II and SE III groups were significantly higher than that of SE I group. Comparison of MNA screening score in elderly patients was as follows : Score for food intake, psychological stress or acute disease, neuropsychological problems, pressure scores or skin ulcer, protein intake, mode of feeding, nutritional status and health status in SE I group were significantly lower than those of SE II and SE III groups. Mobility and drug intake of SE I group were significantly lower than those of SE III groups. Fruit and vegetable intake SE I group were significantly higher than those of SE II and SE III groups. MIS (Malnutrition Indicator Score) was significantly different among the SE I, SE II and SE III groups. We conclude that self-esteem score is positively correlated with protein intake, nutrition status, health status and MIS in elderly care hospital. To improve nutritional status of elderly in care hospitals, systematic nutrition management and self-esteem education program should be implemented.
