Objectives: The aim of this study was to examine factors influencing satisfaction with clinical practice in dental hygiene students. Through this study, we suggested efficient guidance to increase satisfaction levels with clinical practice. Methods: A self-reported questionnaire was filled out by 235 students of clinical dental hygiene in Seoul Gyeonggi Chungcheong Kyongsang and Jeolla province from June 9 to 30, 2017. The questionnaire consisted of questions on general characteristics (6 items), clinical practice characteristics (7 items), ego-resilience (14 items), family support (24 items), teaching effectiveness(35 items), and clinical practice satisfaction (30 items). Data were analyzed using SPSS 19.0. One way ANOVA, the Scheffe Post-hoc test, and the Pearson correlation coefficients were reviewed, and a multiple regression analysis was conducted. Cronbach's alpha of ego-resilience, family support, teaching effectiveness, clinical practice satisfaction were 0.784, 0.892, 0.954 and 0.935, respectively. Results: ego-resilience was 3.24 points, family support was 3.24 points, teaching effectiveness was 2.93 points, clinical practice satisfaction 3.44 points. The meaningful variables which influenced clinical practice satisfaction were the ego-resilience, family support and teaching effectiveness. These factors explained 40.6% of the variance in clinical practice satisfaction. Conclusions: One of the most significant predictors of clinical practice satisfaction in dental hygiene students was teaching effectiveness. Therefore, a teaching program to improve eaching effectiveness should be developed and applied.

Objectives : Insomnia is significantly influenced by the pre-sleep arousal, self efficacy, sleep hygiene, depression and anxiety. The authors tried to explore how these factors are related with the clinical features of sleep. Methods : Fifty three patients diagnosed as insomnia by DSM-IV criteria were studied. They filled up the pre-sleep arousal scale(PSAS), sleep efficacy scale(SES), sleep hygiene awareness and practice scale, BDI, and state and trait anxiety scales. Results: 1) The mean values of sleep-related variables were as follows : Sleep latency,136.89 minutes ; frequences of awakening during a night, 2.28 ; minutes to get back to sleep, 42.70 ; total sleep time, 180.19 minutes ; duration of illness, 72.00 months. 2) The mean scores of scales were as follows : PSAS(cognitive), 22.40 ; PSAS(somatic), 17.32 ; SES, 20.16 ; sleep hygiene knowledge, 25.96 ; caffein knowledge, 59.78 ; sleep hygiene practice, 42.12 ; BDI. 18.2 ; state anxiety, 41.24 ; trait anxiety ; 44.50. 3) In the subjects with superimposed depression, the mean frequency of awakening during a night and the mean pre-sleep arousal scale score were higher than in those without depression. 4) Frequency of awakening were correlated positively with a PSAS(a tight tense feeling in your muscle) and sleep hygiene awareness. PSAS(cognitive) were correlated positively with a PSAS(somatic). BDI correlated positively with a PSAS item(a jittery, nervous feeling in your body)and a SES item (not allow a poor night's sleep to interfere with daily activities). Anxiety scales were correlated positively with sleep hygiene practice scale sleep, and PSAS were correlated negatively with SES. Conclusions : The mean scores of PSAS, SES, sleep hygiene awareness and practice scale, BDI, state and trait anxiety scales of insomniacs were correlated either positively or negatively in insomnia patients. These factors seem to contribute to the development and maintainence of insomnia.

Objectives : The purpose of this study was to investigate the influence of the appearance satisfaction and ego-resilience of dental hygiene students on their employment stress. Methods : A self-reported questionnaire was filled out by 403 female dental hygiene students in five colleges in Chungbuk-do, Gyeongnam-do, and Daejeon. Results : 1. The college students got a mean of $2.78{\pm}0.42$, $3.27{\pm}0.41$ and $2.28{\pm}0.52$ in appearance satisfaction, ego-resilience and job-seeking stress, respectively. 2. Employment stress revealed higher score in poorer financial conditions(p<0.001) and less major satisfaction(p<0.001). 3. Employment stress had a negative correlation to a physical attraction and somatic condition which were the sub-factors of appearance satisfaction. Stress also had a negative correlation to personal relationship and emotional control which were the sub-factors of ego-resilience. 4. Household economy(p=0.023) was identified as a variable that affected job-seeking stress, physical attraction(p=0.048) and somatic condition(p=0.039). Personal relationship(p=0.040) and emotional control(p=0.034) were the influential variables and had 33.2% of explanation power for employment stress. Conclusions : Appearance satisfaction and ego-resilience were the factors affecting job-seeking stress. Therefore counseling and educational programs should be provided for dental hygiene students to look at their own appearance and bodies in a more positive way, to foster their ego-resilience, to relieve and properly cope with employment stress and ultimately to promote their mental health.

The purpose of the study was to investigate the influence of college life adjustment on emotional intelligence in dental hygiene students. Methods: A self-reported questionnaire was completed by 550 dental hygiene students in Daegu from May to June, 2016. The questionnaire consisted of general characteristics of the subjects, emotional intelligence scale, and student adaptation to college questionnaire using Likert 5 point scale. Data were analyzed by t-test, one way ANOVA, post hoc $Scheff{\acute{e}}$ test, Pearson's correlation test, and multiple regression test. Results: The mean scores of emotional intelligence 3.40 points and college life adjustment 3.14 points were above average. Every sub-field of emotional intelligence had static correlation, and there was a close correlation between college life adjustment and every specific field. The academic adjustment (r=0.515) and institutional adjustment (r=0.458) showed strong correlation with the emotional intelligence. The higher the emotional intelligence score was, the higher the college life adjustment was. Variables having statistically significant influence on college life adjustment included economic status, major satisfaction, self-emotional, use of emotional and emotional control (37.7%, p<0.001). Conclusions: Emotional intelligence played a significant role in dental hygiene students to adapt well with the demands of college life. The college should provide the efficient programs in the curriculum that helps enhance emotional intelligence of the students.

Objectives: The purpose of this study was to analyze Influence of stress on oral health and quality of life. Methods: The participants were 172 students from 4 universities located in DaeJeon, South Korea. A questionnaire was administered, assessing the impacts of the general characteristics of the participants, temporomandibular joint (TMJ) symptoms, xerostomia, and halitosis on stress. And oral impacts on daily performance were also investigated. Data were analyzed using the Statistical Package for the Social Sciences 18.0. Results: The level of stress was higher in female, and the causes of stress was reported scholastic achievement, relations with professors, get a job. The students who were higher stress were more conscious of TMJ symptoms, xerostomia and halitosis(p<0.05). Stress was significantly positively correlated with TMJ symptoms (r=0.376, p<0.001), dry mouth (r=0.360, p<0.001), and bad breath (r=0.343, p<0.001). Oral Impacts on Daily Performance (OIDP) scores were significantly positively correlated with dry mouth, bad breath, TMJ symptoms, and stress. Regression analysis showed that 54.5% of the independent variables were related to OIDP scores. Stress and TMJ symptoms exerted a significant effect on OIDP scores. Conclusions: Stress among university students affects oral health and quality of life. Stress coping mechanisms and oral health care education programs should be developed and applied at universities.

Objectives : The aim of this study was to investigate the number of self-report symptoms for temporomandibular disorders(TMD) and related factors in the third grade students of high school. Methods : A total of 1,043 high school the 3rd students age 16 20 completed a questionnaire from 11 high schools in Andong city from April to June 2010. Student's t-test was used to analyze the difference of TMD number. Multiple regression analysis was performed to determine the effects of independent variables on TMD number. Results : 1. Students who have one TMD were 71.3%, two 41.7% and over three 25.7%, respectively. 2. The number of TMD symptom of students who have no good habits such as clenching, bite lip and cheeks, resting on hand, chewing gum, hard foods, and unilateral chewing was a statistically significant higher than those who doesn't have ones(p=0.00). 3. TMD number of students who have been under more stress was a significantly higher than those who didn't have been(p=0.00). 4. Bite lip and cheek(${\beta}$=0.03, p=0.037), chewing gum(${\beta}$=0.03, p=0.029), resting on hand(${\beta}$=0.04, p=0.006), hard foods(${\beta}$=0.07, p=0.000), and stress out(${\beta}$=-0.03, p=0.018) were significantly associated with TMD number by multiple regression analysis. Conclusions : Variables associated with TMD were bite lip and cheek, chewing gum, resting on hand, hard foods, and stress out factor. According to our findings, it is so important to teach good habits on oral health to the 3rd grade students in high school. Further prospective study should explore cause of TDM from those variables.

The purpose of this study was to confirm the relevance of dental health capacity and pulmonary function status. The subjects of this study were adults aged 40 years and older, who participated in pulmonary function and oral examinations. The data used for this study were raw data from the sixth Korea National Health and Nutrition Examination Survey (2013~2015). Statistical analysis was performed by analysis of complex sample survey data. The results were as follows: First, restrictive and obstructive patterns were more prevalent among males than females. They were even worse in older subjects. Approximately 67% of smokers had obstructive pattern. Second, there was a relevance between dental health capacity and pulmonary function status. The functioning teeth index, number of present teeth, and number of sound teeth (ST), which are indicators of dental health, declined with decreased pulmonary function. The number of missing teeth (MT) increased as the pulmonary function deteriorated (p<0.05). Third, the relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant in the tissue health (T-health) index and ST among non-smokers. The relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant (p<0.05) for the T-health index, ST, and MT among smokers. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables. In conclusion, there was a relevance between dental health capacity and pulmonary function status after confounding variables were adjusted. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables.

This study was conducted using the National Health and Nutrition Survey data for 2010-2014 to investigate the relationship between pregnancy-related health factors and periodontitis in adult women. Dependent variable was periodontitis, and independent variables, pregnancy-related health factors(duration of lactation and number of pregnancies) were analyzed. Socioeconomic variables and health-related behaviors were corrected by confounding variables. The number of pregnancies and periodontitis were highly correlated after adjusting for various confounding factors [odds ratio for women with 2-3 pregnancies: 2.66 (95% confidence interval(CI): 1.56-4.54); The odds ratio for women with four or more pregnancies 3.02 (95% CI: 1.70-5.36). In conclusion, periodontitis is closely related to the number of pregnancies and this will be used as basic data for development of oral health education programs for women and pregnant women.

The purpose of this study was to evaluate the relationship between early menopause and periodontal disease in postmenopausal women using data from the 6th Korean National Health and Nutrition Examination Survey (2013~2015). A study was conducted with 2,048 postmenopausal women aged 45 to 74 years. Participants were divided into the early menopause group (menopause occurring at age 45 years or before) and normal menopause group (menopause occurring after age 45 years). A community periodontal index greater than or equal to code 3 was used to define periodontal treatment needs. A chi-square test was used to confirm the bivariate relationship between the variables. Multinomial logistic regression analysis was used to adjust for covariates (age, education, family income, body mass index, alcohol drinking, smoking, visiting dentist in the last year, use of oral care products, frequency of tooth brushing per day). The risk of periodontal disease was higher in the early menopause group after adjusting for potential confounders (odds ratio, 1.59). In particular, the relationship between early menopause and periodontal disease was more evident in women with low education and those who did not use oral care products. The findings of this study suggest that early menopause is a significant factor of periodontal disease in Korean women.

The purpose of this study was to examine the effect of two-dimensional factor of motivators and hygiene on civil servants' job satisfaction using the partial least square structural equation modeling (PLS-SEM) as a technique employed to analyze the measurement and structural models. Exploratory study was deployed to evaluate the relationship among variables. By using multistage stratified sampling, statistical data was collected from a survey of 441 public municipal civil servants who have employed in various levels (municipal government, districts and communes) in Vietnam. The findings provided evidence that hygiene factors (relationship with leader, salary, relationship with coworker and working environment) directly impact on civil servants' job satisfaction. Meanwhile, only career development factor from motivators significantly influenced on public employee's job satisfaction. Based on the empirical results, the hygiene factors of job satisfaction are more dominated that the motivators one. This finding suggests that municipal governments should focus policies on improving the hygiene factors which lead to higher job satisfaction on civil servants. Gaining a thorough understanding of the determinants of job satisfaction toward municipal public servants will enable policy makers to grasp the factors that results in retaining employees. Finally, the policy makers can use this knowledge to promote civil servants' job satisfaction.
