Objectives : The purpose of this study is to identify the effect of office workers' stress level and stress vulnerability on heart rate variability (HRV), confirm the significance of objective stress indicators obtained through subjective stress and heart rate variability devices, and examine their effectiveness as an integrated stress measurement tool in community mental health projects. Methods : From June to July in 2020, 929 workers participated in the stress management and mental health promotion project carried out by K hospital, and their recorded database was used for study analysis with their agreements. Multiple linear regression analysis was performed to find out the effects of general stress level, and stress vulnerability on heart rate variability. Results : All general characteristics were found to have a significant effect on SDNN (ln), RMSSD (ln), LF (ln), and HF (ln), but work experience did not significantly affect RMSSD (ln). Stress level and stress vulnerability did not significantly affect heart rate variability, but stress perception, a sub-factor of stress level, was found to have a significant effect on RMSSD (ln) (β=0.118, p=0.023). Conclusions : In this study, stress perception, a sub-factor of stress level, was found to be a factor affecting RMSSD (ln). This indicates an association with the activity of parasympathetic nerves in stressful situations, and more follow-up studies are needed to use it as a direct indicator of chronic stress and integrated stress in the community mental health field.

The purpose of this study is to find out how the adult's mental health in Korea has an impact on the quality of the life. By using '2010 National Health and Nutrition Examination Survey' data, 4,211 people among 20-year-old to 59-year-old adults were enrolled in this study. Frequency and percentage t-test using the SPSS WIN18.0 Multiple regression analysis was conducted and the results of this study are as follows. First, it is showed that in the 20s and 30s the females are a little more sleep than the males regarding the relationship between sleeping hours and the quality of the life of adult men and women. However, there are no differences between the 40s and 50s groups. Second, it is indicated that adult men are higher than women for the subjective health status when it comes to the subjective health status and the usual perceived stress. Although there are no statistical differences according to the gender in the 40s and the 50s, they have a little stress in general. Third, it is confirmed that only the subjective health status and usual stress perception give an beneficial influence on the quality of adult's life in the adult's mental health variations and the quality of life. In summary, this study was found that the adults in the 20s and 50s could increase their satisfaction of their life if they have more positive thinking and less stress from their life. Therefore, the systematical education and programs to manage the health and stress are required.

Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

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.

This study is targeted at introducing the three aspects of speech timing (articulatory, acoustic and auditory) and discussing their strong and weak points in describing speech timing. Traditional (extrinsic) articulatory timing theories exclude timing representation in the speaker's articulatory plan for his utterance, while the (intrinsic) articulatory timing theories headed by Fowler incorporate time into the plan for an utterance. As compared with articulatory timing studies with crucial constraints in data collection, acoustic timing studies can deal with even several hours of speech relatively easily. This enables us to perform suprasegmental timing studies as well as segmental timing studies. On the other hand, perception of speech timing is related to psychology rather than physiology and physics. Therefore, auditory timing studies contribute to enhancing our understanding of speech timing from the psychological point of view. Traditionally, some theories of speech timing (e.g. typology of speech rhythm: stress-timing; syllable-timing or mora-timing) have been based on our perception. However, it is problematic that auditory timing can be subjective despite some validity. Many questions as to speech timing are expected to be answered more objectively. Acoustic and articulatory description of timing will be the method of solving such problems of auditory timing.

This study aimed to evaluate the health concern, eating habits, dietary behavior, and psychological stress among middle-aged adults in Chungnam according to their exercise status. A total of 437 adults with a mean age of 42.6 years participated in this study and completed a questionnaire survey. The subjects were divided into one of three groups according to their exercise status: never doing exercise (NDE; n=144), doing exercise once a week (DEO; n=186), and doing exercise twice a week or more (DET; n=107). Results demonstrated significant differences in concern about health, subjective health status, meal regularity, dietary problems, and stress score among the three groups. The DET and DEO groups were more concerned about their health (p<0.001), and had a perception that their health status was better than that of the NDE group (p<0.01). A larger percentage of the DET group had breakfast everyday (p<0.05) and a smaller percentage of the DET group had dietary problems such as irregular mealtime and skipping meals (p<0.01), compared to the other groups. The average stress score of the DET group was significantly lower than that of the DEO and NDE groups (p<0.05). The results reveal that doing regular exercising at least twice a week is associated with higher health concern, more desirable dietary habits, and lower psychological stress in middle-aged adults. These findings support the beneficial effects of regular exercise for health, dietary habits, and stress control.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.

The purpose of this study was to investigate weight control and the relative influence of individual variables affecting children's attempts to control weight. The study subjects were 319 elementary school children. First, the average body height and weight of the children who participated in this study was somewhat larger in boys and similar in girls, as compared with the normal body shape of Korean children. More boys were classified as overweight than girls, based on BMI. Both boys and girls were dissatisfied with their body shape, and especially the girls showed higher dissatisfaction rate than the boys did. Almost half of the children were concerned about weight control and girls had higher concern than boys. Of the children, 38.8% had controlled their weight; however there was no difference between their sexes. There were significant differences between children who had and had not experienced weight control in the following variables: stress caused by obesity, body satisfaction, BMI, subjective body shape perception and concern about weight control. Therefore, discriminant function analysis was performed to determine the discrimination of these variables between the two groups. From the analysis results, the most critical factor was BMI in the boys and concern about weight control in the girls. This finding should be reflected in the design of weight control programs for children i.e., boys should be encouraged to perceive correctly their own body shape and to control weight by maintaining a well-balanced diet and moderate exercise over a long period of time, rather than by skipping meals, while girls should be inspired with sound values and attitudes regarding their body shape, rather than provided with the concrete information on how to control weight.
