Background: Social distancing by working-from-home is an effective measure to decrease the spread of COVID-19. However, this new work pattern could also affect the well-being of workers. Therefore, the aim of the study was to study the magnitude of occupational health problems and lifestyle changes among workers who have only recently started working from home. Methods: A cross-sectional study was conducted using online self-administered questionnaires during the coronavirus disease 2019 pandemic in the Bangkok metropolitan area, Thailand. The participants were from any organization that allowed working from home. The demographic data including the analysis of the characteristics of working from home, the occurrence of occupational health problems, and the lifestyle changes caused by working from home were analyzed. Results: A total of 869 workers were included as study participants. The highest prevalence of physical health problems among all workers was identified to be weight gain at a rate of 40.97% (95% confidence interval = 37.69-44.24), and the highest prevalence of psychosocial problems was identified to be cabin fever at a rate of 31.28% (95% confidence interval = 26.66-35.90%) among full-time working-from-home workers. The health effects that were significantly related to the intensity of working from home (p for trends <0.05), either positively or negatively, included body weight changes, ergonomic problems, indoor environmental problems, and psychosocial problems. Meanwhile, the lifestyle changes related to work intensity included eating pattern, sleep habits, and exercise. Conclusions: Working from home can affect workers' well-being in various aspects. Hence, occupational health providers must prepare for risk prevention and health promotion in this "new normal" working life pattern and for future pandemics.

Human needs energy to maintain metabolisms, and these energy sources were uptake foods or nutritions. The most effective source was known for glucose among the nutrients, furthermore the glucose is an important source of energy for blood cells and control brain maintenences cells. But as food is plentiful and eating habits become more westernized, fast food and irregular meal times by works. Nowadays, diabetes were rapidly increased by malnutriton and obesity. Diabetes was the sixth highest on the list of causes of death in Korea, released by the Statistics Korea in 2015, which is considered a serious social problem for adult diseases. Therefore, this study aims to establish the optimal hot water extraction conditions of mixed herbs extract mixture compounds that are effective in diabetes. The independent factors were extraction temperature (X1: $40-120^{\circ}C$), extraction time (X2: 2-10 hrs.), and the ratio of water to sample (X3: 40-200 mg/mL). Their effects were assessed on dependent variables of the extract properties, which included soluble solid contents, Brix of sample extract, total polyphenols content, total flavonoids content and DPPH Radical scavenging activity. As a result, the content of total polyphenol content was the highest in No.12(6 hrs, $120^{\circ}C$, 67 mg/mL) and the highest total flavonoid contents was found in No.16(6 hrs, $80^{\circ}C$, 40 mg/mL). DPPH Radical scavenging activity showed the highest activity in No.7(8 hrs, $100^{\circ}C$, 100 mg/mL).

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

Objective: In this study, the dental health care knowledge, dental health behaviors and dental health status of elementary school students were compared and analyzed in the cases of their schools having dental health care center or not one. Methods: The target groups were 167 students of A school (experimental group) where pit-and-fissure sealants, fluoride mouthrinsing, and fluoride gel application were carried out with all grades of students by school dental health care center and 158 students of B school (control group) where fluoride mouthrinsing, for all grades students and pit-and-fissure sealants for the first grade students are carried out but have no the school dental health care center. Results: This study was carried out through the answer sheets and recordings of dental inspection. The findings of this study are as follows: 1. The dental health care knowledge was compared and the results showed that on average 14.2$\pm$2.1 in experimental group and 14.0$\pm$1.9 in the control group were no significantly different (p>0.05). 2. The dental health behaviors were compared and the results showed that the experimental group was significantly different(p<0.05) in terms of the number of times of dental brushing a day, the method of tooth brushing, the time of tooth brushing, the experience of tooth brushing with fluorine, the kinds of snacks and tooth brushing in school after lunch. But there was no significant difference(p>0.05) in the time of tooth brushing and the tooth brushing after eating snacks. 3. The DMF rate was compared and the results showed the significantly difference between the average experimental group and 53.8$\pm$5.0 in the control group(p<0.05). 4. The DMFT index was compared and the results showed the significantly difference between the average 0.6$\pm$2 in the experimental group and 1.4$\pm$1.6 in the control group(p<0.05). 5. The DMFI rate was compared and the results showed the significantly difference between the average 4.2$\pm$8.3 in the experimental group and 9.5$\pm$11.0 in the control group. (p<0.05). 6. The DT rate were compared and the results showed the significantly difference between the average 10.2$\pm$29.5 in the experimental group and 32.4$\pm$44.0 in the control group(p<0.05). 7. The FT rate were compared and the results showed the significantly difference between the average 88.5$\pm$31.0 in the experimental group and 67.5$\pm$44.0 in the control group(p<0.05). Conclusions: Based on the results, above there was no significant difference in dental health care knowledge between both the experimental and the control group. But we discovered that the experimental group is better than the other one in dental health care behaviors and dental health status. Therefore, we could conclude that the school dental health care center efficiently carried out the dental care and treatment. As school dental health care centers did not work out efficiently in terms of their educating on the dental health acre knowledge, the related programs to be developed and supported.

The aim of this study was to investigate the effect of sleep duration on dietary habits and body composition of university students. Sleep duration has recently been added to the list of risk factors for obesity. However, studies on this topic are fairly limited particularly in Korea. We studied the relationship between the duration of sleep and obesity principally based on body mass index and %body fat in university students. For this purpose, a survey was conducted on a total of 312 university students. The subjects enrolled for this study were divided into two groups: (1) those with sleep duration of <7 hours (148 students) and (2) those with sleep duration of >7 hours (164 students). Based on a self-reporting method, the participants filled up the questionnaires for more than 20 minutes. Based on the overall data obtained, we observed that most students (52.88%) skipped breakfast. This was mainly due to shortage of time (60.58%). We also observed that self-reporting dietary preferences included eating irregular meals (49.04%), overeating (19.55%), imbalanced diet (16.35%), and skipping meals (9.94%). It was found that cookies were the favorite snacks in the majority of the participants (50%). Our data reveal that the body mass index, fat mass, visceral fat, and subcutaneous fat, respectively of the shorter sleep duration group (<7 h/day) were 23.78 $kg/m^2$, 19.13 kg, 2.23 kg, and 11.15 kg. In contrast, in those of the control group (7 h/day), these values were found to be 21.84 $kg/m^2$, 13.88 kg, 1.56 kg, and 12.11 kg. We also observed that there were significant correlations of sleep duration with body mass index (p<0.05), fat mass (p<0.01), visceral fat (p<0.01), and beck depression score (p<0.01). Our data suggest that the body mass index in the shorter sleep duration group was higher than that of the control group; however, %fat, visceral fat, and subcutaneous fat in the shorter sleep duration group were found to be higher than those of the control group. The data obtained through our study suggest that short sleep duration is clearly associated with a modest increase in general and abdominal obesity particularly in university students.

Objectives: This study examined to explain the practical health behaviour and health-related quality of life, and their influencing factors in high school students. Methods: Total of 718 high school students from 1 school in Seoul were assessed with a self-administered questionnaire regarding general characteristics, health related characteristics, obesity index(Height and weight calculated by using the relative weight law: obesity group>20%, overweight group $10{\sim}20%$, normal weight group $-10{\sim}10%$, under weight group <-10%), health behaviour in school-aged children(eating, exercise and weight control) and health-related quality of life(PedsQLTM4.0 Generic Core Scale: physical health, emotional functioning, social functioning, school functioning). Results: Major results were as follows. 1. The rate of obesity by obesity index was 5.3% of high school students. Obesity incidence in adolescents was mainly associated with gender and parents whether obesity. 2. Perceived health status was lower in obese adolescents than in normal adolescents. 3. The rate of miss a breakfast was 37.9%, and obesity group than normal weight group were fruits, vegetables and milk intake at least, a lot of fastfood intake. During the past week, followed by intense physical activity, and overweight consumed a lot of time for TV and the Internet. Overall, under weight group and normal weight group belong to the students evaluated fatter than themselves. Weight control for weight loss, gain and maintain was grater in obesity group than in normal weight group. Weight loss showed highest scores in overweight group which appeared significant difference. 4. Obese adolescents compared with other groups, reported lower total QOL score and all QOL in domain, and especially social functioning showed significant differences. 5. Factors influencing the adolescents's QOL were found to be gender, perceived health status and exercise. Conclusions: High school girls were aware of their bad health status and likely to improve the QOL by practicing health behaviour. But obese adolescents were likely to degrade the quality of life by reducing the practice of health behaviors. So further school-based education about proper practical health behaviors and obesity prevention is necessary.

This study was intended to provide basic data of nutrition education to a prevention of obesity and living patterns of elementary school students. Through the measurment of the actual obesity rate of children for students who were in the fifth and sixth grades of elementary school as well as their mothers, and by analyzing obesity-related factors. Children have started to have the characteristics obesity and obesity problems. 1. There were total 234 children including 133 boys (56.8％) and 101 girls (43.2％) for the study. There were 80 children in the fifth grade (34.2％) and 154 children in the sixth grade (65.8％). 2. Among the subjects 20.1％ were obese. By gender, the obesity rate of boys (27.1％) was higher than that of girls (l0.9％)(p＜0.01). By grade, children in the fifth grade (26.3％) had higher obesity rate than children in the sixth grade (l6.9％)(p＜0.05). 3. In terms of the educational level of parents, the obesity rate of children of parents who received university and／or higher education was 27.5％ (p＜0.05). 44.1％ of parents answered ‘I almost never give snack’s’(p＜0.01). 4. There was 32.8％ for an irregular quantity of meal. There was no obese child who under-ate (p＜0.05). In terms of impulse eating, ‘I eat.’ and ‘I don't eat.’ were 24.4％ and 25.9％ respectively. The obesity rate of the case of ‘I eat only food I like.’ was 10.6％ (p＜0.05). In terms of the obesity rate based on the daily average meal frequency, there was the highest rate of 26.1％ for I average meal frequency per day, 13.0％ for 2 daily average meal frequency, and 7.4％ for over 3 average meal frequency per day (p＜0.05). For a degree of a physical activity, the group of active physical activity (p＜0.05) and the group which liked the physical exercise showed a lower obesity rate (p＜0.001). The obesity rate of children who had regular exercise was 11.8％. It was lower than the obesity rate (24.8％) of children who didn't exercise (p＜0.01). The higher exercise frequency per week was, the lower the obesity rate was(p＜0.01). In terms of the exercise time, there was 8.3％ for over 60 minutes and 28.9％ for less 15 minutes. The group which had the long exercise time showed a lower obesity rate(p＜0.05). As the result, the education for obesity must enable students to recognize the warning signs for obesity and control their own weight with proper living patterns, by modifying behaviors considering the degree of obesity. Obesity must be controlled by the prevention and education connected with the family for all students as one of the school health programs. There must be also the development of a program through individual consultation considering the degree of obesity.
