The relationship among food behavior, psychological factor(life strees) and perceive tiredness was investigated in 514 adolescents. Tiredness was measured in four cases: in lessons, before school, in the early evening and at weekends. Adolescents felt most tired in lessons and before school, and leat at weekends. Irregularity of meal times and skipping breakfast were positively correlated with tiredness in lessons and befor school. Consumption of some foods was related to perceived tiredness. High sugar or fat containing ice-cream, hamburger of fizzy drinks in boys, and crisps and cookies in girls were positively associated with tiredness. Whereas beans and mushrooms were negatively associated with tiredness in girls. Life stress(by scholastic problem and personal problem) of adolescents was positively related to tiredness. The contribution of stress to tiredness was much greater than of food behavior according to multiple linear regression .There was no relationship between nutrients intake and tiredness in lessons and before school which were more strongly influenced by stress, whereas the relationship was found at weekend without influences of stress. The more tired, the lower NARs(nutrient adequacy ratio) of energy, phosphorus, vitamin A, vitamin B$_2$, and niacin were. In conclusion, some eating behavior and psychological factor can cause tiredness in adolescents, but tiredness in school and before school had more of a psychological cause than at weekend.

This study was conducted to find out the degree of tiredness, accumulated tendencies of fatigues in accordance with 3 types of circadian rhythms and 3 types of perceived fatigue signs such as physical, psychological and neurosensory aspects in before and after work at night. Samples were chosen from the 217 intensive care units nurses working in 13 general hospitals which had 3 shift rotating systems, Data were collected from November to December in 1999. Two hundreds seventeen respondents were classified by 3 circadian types such as 59 morning, 110 middle and 48 evening. Circadian type was measured by the circadian type scale which was designed by ${\ddot{O}}stberg$ and Home (1976). in order to estimate the level of tiredness, the investigator used the fatigue checklist designed by the Labor and Health Institute of Japan(1970). Analysis was done by frequency a percentages, ${\chi}^2$ test and repeated measures ANOVA test. The result of this study were as follow: 1. In the general characteristics of the subjects circadian types, moderate type had the large proportion at 50.7% and morning type had 27.2% and evening type had 22.1%. 2. According to the 3 types of fatigue signs, the highest general tendency was 'General weakness' and 'Feeling of headsore' for physically perceived sign, 'Drowsiness' for psychological sign, and 'Uncomfortableness in sight seeing' for neurosensory sign. 3. The most frequently complained fatigue were observed in physical symptoms among physical, mental, and neurosensual symptoms. The percentage of complained was higher after night work than before the work started. 4. There was not any statistical significant difference between the circadian type and the degree of physical, mental, neurosensory fatigue. 5. There was not any statistical significant difference in regarding to each date of night shift except difference between 1st and 2nd days of fatigue perceived physically. Therefore, the study concluded that the fatigue perceived by night shift nurses might be related with shift working condition rather than circadian types.

The purpose of this study was to identify how attitudes toward menopause and family-related variables (living with a first child, satisfaction with children, and marital satisfaction) were associated with the perceived menopausal symptoms of middle-aged Korean females. Data for the study were based on a community sample of 628 women whose ages ranged from 45 to 60, who were currently married and had at least one child. The respondents reported lower levels of menopausal symptoms, medium levels of marital satisfaction and slightly higher levels of satisfaction with children. Feelings of tiredness, irritability, and nervousness without apparent reason, and aches in the lumbago and joints were common menopausal symptoms reported in this study. Regression analysis was conducted to investigate the effects of monthly income, educational level, employment status, attitudes toward menopause, living with a first child, satisfaction with children, and marital satisfaction on perceived menopausal symptoms. Attitudes toward menopause, living with a first child, satisfaction with children and marital satisfaction were significantly associated with perceived menopausal symptoms. In particular, marital satisfaction had the strongest effect on perceived menopausal symptoms. The results showed that in the face of the developmental challenges experienced during the menopausal transition, family-related variables served as positive reinforcement for married middle-aged women. This finding suggests that in order to improve the menopausal transition, family education programs need to be developed and offered to middle aged females who suffer from severe menopausal symptoms.

This study was carried out through questionnaire in order to investigate the self-recognized monosodium glutamate (MSG) symptom complex in the eating out of housewives. The subjects were 503 housewives in Inchon and the results are summarized as follows. As for age, 51.9% of subjects were over 40 years old. Also 60.0% of the subjects received a high school education. As for occupation, full-time housewives accounted for 63.7%. Monthly household income of most subjects were 1 million won or more, and monthly food expenses for most subjects were over 300 thousand won or more. Also 71.0% of the subjects lived in apartments. As for frequency of eating out, 69.5% of subjects ate out I~2 times a month, 21.6% did 3~4 times a month, 4.5% did 7 times or more/month and 3.6% did 5~6 times a month. The higher education level, family income or food expense of subjects were, the more they ate out. Most subjects selected the menu of eating out according to preference of family. Also 63.6% of the subjects considered the amount of MSG in eating out. As for menus containing high amount of MSG, 55.8% of subject answered Korean dishes, 31.1% did Chinese dishes. After eating out, 25.1% of subjects perceived MSG symptom complex, such as thirst, tiredness and rapid heart beat, etc. Therefore, it may be necessary to reduce the amount of MSG in eating out and to develop safe and delicious menus of eating out using various natural foods.

Background: Coal mining is of significant economic importance to the Australian economy. Despite this fact, the related workforce is subjected to a number of psychosocial risks and musculoskeletal injury, and various psychological disorders are common among this population group. Because only limited research has been conducted in this population group, we sought to examine the relationship between physical (pain) and psychological (distress) factors, as well as the effects of various demographic, lifestyle, and fatigue indicators on this relationship. Methods: Coal miners (N = 231) participated in a survey of musculoskeletal pain and distress on-site during their work shifts. Participants also provided demographic information (job type, age, experience in the industry, and body mass index) and responded to questions about exercise and sleep quality (on-and off-shift) as well as physical and mental tiredness after work. Results: A total of 177 workers (80.5%) reported experiencing pain in at least one region of their body. The majority of the sample population (61.9%) was classified as having low-level distress, 28.4% had scores indicating mild to moderate distress, and 9.6% had scores indicating high levels of distress. Both number of pain regions and job type (being an operator) significantly predicted distress. Higher distress score was also associated with greater absenteeism in workers who reported lower back pain. In addition, perceived sleep quality during work periods partially mediated the relationship between pain and distress. Conclusion: The study findings support the existence of widespread musculoskeletal pain among the coal-mining workforce, and this pain is associated with increased psychological distress. Operators (truck drivers) and workers reporting poor sleep quality during work periods are most likely to report increased distress, which highlights the importance of supporting the mining workforce for sustained productivity.
