Objectives: The major objective of this study was to analyze insomnia after the change to consecutive day shift from day and night shift in a motor assembly factory. Materials: Data were collected at before and after shift system change through a survey conducted by a labor union. We analyzed transition of PSQI(Pittsburgh Sleep Quality Index) among 222 workers by separating the day shift week and night shift week. The cut-off point of insomnia was 8.5 on the PSQI. Results: Mean PSQI in the day shift week significantly did not decrease, going from $6.36{\pm}3.23$ to $6.46{\pm}3.00$(p=0.612 by paired t-test), Mean PSQI for night shift week significantly decreased from $8.31{\pm}3.36$ to $6.19{\pm}3.18$(p<0.001 by paired t-test). However, mean PSQI in the day shift week increased from $6.33{\pm}3.83$ to $7.11{\pm}2.86$ in ${\geq}50$ years(p=0.085, by repeated measured ANOVA). Mean PSQI score in the night shift week improved more in the married group(from $8.38{\pm}3.27$ to $6.12{\pm}3.18$) than in the non-married group(from $7.82{\pm}3.27$ to $6.12{\pm}3.18$)(p=0.038, by repeated measured ANOVA). Conclusions: The change to consecutive day shift improved insomnia in night shift. However, insomnia in the day shift week was worsened among those more than 50 years old.

This paper aimed to study on the relevance of mental health and oral health. The subjects were recruited total 3,261 elderly of over 40 years old, using the Sixth Korea National Health and Nutrition Examination Survey(KNHANES). All the collected data were analyzed by chi-square test, t-test, and logistic regression using SPSS 23.0 version. Logistic regression was used to analyze the relationship of sleeping time or stress and the number of remaining teeth, and 95% confidence intervals were computed. Sleeping time odds ratio(OR) of the number of remaining teeth was 1.52 (95% confidence interval: 1.074-2.135) and Stress odds ratio(OR) was 2.39 (95% confidence interval: 1.855-3.090), but there is no statistically significant difference after adjusted age, gender and other variables.

Purpose: This study was conducted to provide basic data for a health promotion program by analyzing the effects of high school students' mental health-related factors on oral symptom experiences. Methods: This study included 24,833 high school students who participated in the screening and health survey in the "17th (2021) Adolescent Health Behavior Survey." SPSS software (SPSS Statistics ver. 21.0; IBM) was used for statistical analysis. Multiple sample logistic regression analysis was performed. The significance level was set to 0.05. Results: The result of the analysis on the effect of mental health revealed that oral symptom experience was low in students without depression and suicidal thoughts. Oral symptom experience was high in students with stress perception. Additionally, the experience of oral symptoms was low when there was sufficient subjective sleep. Conclusion: Therefore, it is necessary to develop a customized oral health education program for early detection of oral symptoms and oral health promotion in high school students. Furthermore, it suggests the need for strategies and continuous oral health guidance to practice proper oral health habits to maintain healthy oral conditions.

Objectives: This study aimed to evaluate the effects of occlusion patterns using the T-scan $III^{(R)}$ system and oral parafunctional behaviors on temporomandibular joint disorder (TMD) in female college students. Methods: A questionnaire survey assessed TMD symptoms and oral behavioral checklist (OBC) scores in 120 female college students in their early twenties. Occlusion was evaluated using the T-scan $III^{(R)}$ system. Logistic regression analysis was performed to investigate the relationship between occlusion and OBC scores based on patients' symptoms of TMD and to determine whether OBC scores were a predictor of TMD. Results: A total of 101 participants with an average age of 22 (${\pm}2.17$) years were included in the analysis. The reported symptoms of TMD were categorized as moderate (28.8%), slight (27.7%), severe (25.7%), and asymptomatic (17.8%). Occlusion was analyzed using the T-scan $III^{(R)}$ system, and the mean occlusion time was 0.42(${\pm}0.5$) seconds. The results of logistic regression analysis showed that the group that would 'clench or grind teeth' during sleep showed an odds ratio for TMD that was 8.9 times higher than that in the group without this behavior. The group that would 'hold, tighten, or tense muscles without clenching' while awake showed an odds ratio for TMD that was 21.3 times higher than that in the group without this behavior. Conclusions: We confirmed that oral parafunctional behavior affects TMD. Therefore, we would like to continue studying the diagnosis and treatment of TMD by evaluating occlusion patterns and related OBC scores.

This study was conducted to examine the effects of auricular acupressure on quality of sleep and depression. Adults who had insomnia for over 1 month were recruited. Participants were distributed randomly to the experimental group(n=22) and the control group(n=22). The experimental group received auricular acupressure on Shen men(TF2), insomnia 1(SF4), insomnia 2(SF1), and anti-depression(LO8) for 1 week. The contrast group received sleep hygiene education. The mean differences of the quality of sleep were 4.05±2.52 in the experimental group and 1.45±3.77 in the control group. Auricular acupressure significantly decreased insomnia in the experimental group compared to the control group(t=3.07, p=.004). Depression scores after acupressure were not different between the experimental group and the control group. After controlling the religion as a covariate, the mean difference of depression in the experimental group was higher than the control group(F=4.22, p=.046). In conclusion, auricular acupressure decreased insomnia and depression. Therefore, further studies on different acupressure points such as shen men, jiao gan, heart, pi zhi xia, and endocrine are recommended.

To examine the relationship between occurrence of oral malodor and smoking, drinking, oral health behavior characteristics. A total of 144 adults were measuring the malodor by use of Oral Chroma volatile sulfur compounds. Data were analyzed with t-test, one-way of variance and multiple regression analysis using SPSS 12.0. hydrogen sulfide($H_2S$) was indicated to be so higher concentration in the group of carrying out scaling sometimes than the regularly group(p<0.01). methyl mercaptan($CH_3SH$) was indicated to be higher concentration in previous smoker than non-smoker and smoker(p<0.05), smoking for over 20 years was higher than the under 20 years group(p<0.05). The group of drinking over 5 times a week was indicated to have higher concentration than the under once-twice a week group(p<0.01). The group of not toothbrushing before going to sleep had higher concentration than the group of toothbrushing before going to sleep(p<0.05). The group of scaling sometimes was indicated to have higher concentration than the group of scaling regularly(p<0.05). dimethyl sulfide($(CH_3)_2S$) was indicated to be higher concentration in the group with over 2 bottles of Soju than in the group with under 1 bottles of Soju(p<0.01). The regular scaling will need to be carried out in the preventive dimension for managing oral malodor. The guidance on non-smoking and moderation in drink will need to be surely included.
