To investigate the sleeping patterns and gastrointestinal disorders of shift workers, the author studied 434 female workers who worked at textile industry ill Taejon city from September 1,1992 to September 31,1992. Shift pattern were divided into 3 categories ; 3 shift(shifts per 8 hours), 2 shift(day and night shift) and day work. The results obtained were as follows : 1 The average sleeping hours when adjusted for the education level of the total study subjects was 6.1 hours. That of 3 shift workers was 6.1 hours, 2 shift workers was 6.0 hours, but that of day workers was 6.5 hours. There were no significant difference among the shift workers. 2. For the 3 shift workers, the average physiologic adjusted duration in day shift (2.2 days) was shorter than that of night shift(2.7 days) and there were significant difference among the rotating shift works (p<0.001). The sleeping problems in day shift was less than those of night shift (p<0.001). 3. 44.9% of 3 shift workers, 39.3% of 2 shift workers and 33.1% of day workers complained gastrointestinal symptoms when adjusted for the age, education level, job tenure, work post. And the rates of gastrointestinal symptoms complained increase with job tenures (p<0.001). 4. The most frequent gastrointestinal diseases were gastitis and gastric ulcer with 14.2% , Irritable bowel syndrome with 3.1 %, duodenitis and duodenal ulcer with 2.1% and combined gastrointestinal disease with 2.1%. Age, eating habit, amount of coffee per day, job tenure, work post and shift pattern showed no significant difference with the gastrointestinal diseases when adjusted for the age. According to the above results, the author suggested that the shift pattern and job tenure can affect to the sleeping problem and gastrointestinal symptoms.

This study was conducted to investigate the nutrition knowledge, dietary attitudes, dietary behaviors, smartphone usage-related dietary habits, and health-related lifestyles of higher grade students in elementary school according to risk level of smartphone overdependence. Subjects were 286 fifth and sixth grade students of elementary school in the Siheung and Ansan areas. Data were collected using self-administered questionnaires and analyzed using SPSS v. 20.0. Based on scores of S-scale (smartphone overdependence scale for adolescents), subjects who used smartphone were classified into an overdependence group (ODG, n=52) and a normal group (NG, n=234). The ODG showed a significantly longer usage time than NG on both weekdays and weekends (p<0.001). There were no significant differences in total scores of nutrition knowledge between the ODG and NG. Average total scores of dietary attitude and dietary behavior in the ODG were significantly lower than in the NG (p<0.001). There were higher risks of ODG for skipping meals (OR=8.3, 95% CI=4.027-17.099), changing eating speed (OR=4.4, 95% CI=2.209-8.822), and changing meal amount due to smartphone usage (OR=2.9 95% CI=1.233-6.623). Therefore, education programs are needed to ensure proper dietary behaviors and habits among smartphone overdependent elementary school students.

This study was carried out for analyzing pathological and epidemiological factors of osteoporosis and doing pilot test using trial compounds of tuna bone and oriental herbs based on the factors. Osteoporosis is originated from osteoblast, osteoclast, organic and inorganic factors etc. Therefore the pathology of osteoporosis is not simple because the cytokine, growth factors and hormones of the components are various a lot. Taking a view of epidemiological factors of type I osteoporosis, ageㆍmenarcheㆍcholesterolㆍBMI etc. have definite relation to them. So we can approach to aging or consumptive disease in oriental medicine, specifically differential diagnosis of blood depletion with deficiency of qi, deficiency of kidney, deficiency of yin, bony weakness etc. And it should be considered together with rules for maintaining good health or habit concomitantly. Therefore IL1ㆍ6 or TNF αㆍβ are generally used as molecular biological index for osteoblast and osteoclast because the most important index is bone mineral density and strength, but the factors like collagen and noncollagen protein must be accounted as biomarkers. Trial compounds generally showed favorable effects on accompanying subjective symptoms of osteoporosis in the pilot test for menopausal woman. But if she didn't have specific symptoms of osteoporosis there wasn't any specific change. And osteocalcin was increased in case of being under standard level, but wasn't changed in case of normal level. Therefore these trial compounds can be used as a funcdonal diet for type I osteoporotic patients or preventive measures.

The purpose of this study was to investigate the dietary habits and the consumption patterns of convenience foods by university students according to where they reside. The subjects were 572 university students in Changwon and Masan who were divided into three groups by their residential type; students living with their parents (n=297), self-boarding students (n=139), and students living in a dormitory (n=136). This survey was conducted using a self-administered questionnaire. Among all students, 22.4% skipped breakfast, and the major reason was lack of time (38.1%). Convenience food intake at lunch was 39.1%, and that of snacks was 35.4%. In particular, convenience food intake at lunch was 45.9% for students living with their parents, 30.9% for those self-boarding, and 32.6% for those living in a dormitory (P<0.01). Approximately 66% of the students said that the reason they bought convenience food was that it was easy to cook. Those who were residents of a house (P<0.001) believed that nutritional imbalance was a problem with convenience food. The students who lived in the dormitory ate frozen fried pilaff (P<0.01), canned vegetables (P<0.05), packed kimchi (P<0.001), and Ramyon cups (P<0.001) more, while the self-boarding students ate Ramyon (P<0.05) more. The results suggest that it is necessary to educate people how to buy reasonably by understanding the interrelationship between convenience food and health care and by checking the nutrition index label on convenience foods.

We studied teachers' breakfast habits and their preferences on various breakfast types so that we will furnish data to nutrition education including ideal breakfast habit and development of various menus. The meal considered as most importantly were dinner (66.2%), fellowed by lunch(21.6%), all three meals(6.4%) and breakfast(5.8%). Men considered breakfast more importantly than women. On the contrary, women considered dinner more significantly compared to men. The group aged 45 and over emphasized breakfast and all three meal. 78.1% of subjects answered that breakfast is necessary and 61.5% of subjects ate breakfast regularly. Those who have breakfast regularly was lower in women(50.0%) than in men(71.3%). Instead, those who eat breakfast irregularly or skipping it was higher among women(50.0%) than among men(29.7%). The percentages of having breakfast regularly was higher in older groups. For breakfast, 82.1% of subjects had conventional meal which included rice, soup and Kimch. On the other hand, 13.9% of subjects had Western style breakfast such as bread, cornflakes and milk. The major reason for eating breakfast regularly was answered as 'maintain health(71.8%)'. The major reason for eating breakfast irregularly or skipping was 'don't have enough time to eat(48.0%)', 'poor appetite(28.6%)'. The major physical discomfort after skipping breakfast was 'experience brash(35.6%)', 'lack of physical strength(35.1%)'. Subjects answered that breakfast served as 'source of physical strength(64.9%)', 'provides nutritional balance for a day(21.1%)' and 15.0% of subjects ate out breakfast. Therefore, it is suggested that teachers as well as school children be provided breakfast and snack in school. The preference and opinion regarding breakfast types wer conventional food including rice, soup and Kimch(67.0%). There was a little preference in Western style food such as bread, milk and coffee(14.3%), cereals mixture and porridge(10.7%). It was noticeable that 49.1% of females and those who reside in Seoul(42.2%) selected various breakfast types excluding conventional food. Therefore it will be accepted to working women as breakfast if it is nutritionally balanced and cook well in short time.

The present study was conducted to evaluate nutrient intakes of industrial workers with hyperlipidemia and cholesterol-saturated fat indices(CSI) of their daily meals and various side dishes accompanied with alcohol. Thirty eight male subjects of 41.0$\pm$6.5 years whose average serum cholesterol and triglyceride levels were 222.9$\pm$37.7 and 282.3$\pm$139.3mg/이 were interviewed on daily intakes of foods and drinking habits including types and amounts of side dishes using 24-hour recall and questionnaire methods. Average energy habits including twenty six non-drinkers and twelve drinkers were 2365$\pm$41 and 2822$\pm$417kcal, respectively but intakes of other nutrients were not very different between two groups. Carotene intakes was, however, low in drinkers. Intakes of saturated fat, cholesterol and CSI of subjects' daily meals were 15.4$\pm$5.4g, 229$\pm$114mg and 27.1$\pm$10.4 for non-drinkers and 18.7$\pm$7.8g, 238$\pm$69mg and 30.8$\pm$9.8 for drinkers. CSI of their daily meals varied from 10 to 60 without much differences in energy values and were positively correlated with serum cholesterol levels(r=0.2606, p<0.05). Average alcohol intakes obtained from subjects' drinking habit was 89.5$\pm$46.8g per day and major side dish was roasted beef giving 660$\pm$234kcal of energy and 24.3$\pm$8.0 of CSI. From the present study, it is concluded that industrial workers are more prone to have hyperlipidemic diets due to alcohol. To improve their diet and health, an appropriate nutrition education should be necessary and CSI of various Korean foods and meals can be used as handy self-control education tool.

Objectives: This study aimed to develop nutrition education program for consumers to reduce sodium intake based on social cognitive theory (SCT). Methods: The main factors of SCT related to low sodium diet were investigated by using focus group interview (FGI) with 30 women who participated in consumer organizations. Results: The main target groups for the education program were housewives (H), parents (P), and the office workers (OW), for which we considered their influences on other people and the surroundings. According to the results of FGI, in carrying out low sodium diet, 'positive outcome expectation' were prevention of chronic disease and healthy dietary habit, and 'negative outcome expectation' were low palatability of foods, difficulty in cooking meals, and limited choice of foods. The contents of the program and education materials were individualized by each group to raise self-efficacy and behavioral capability, which reflected the results of the FGI. The program included 'salt intake and health' to raise positive outcome expectation. For improving the ability to practice low-sodium diet, the program contained the contents that focused on 'cooking' and 'food purchasing' for H, on 'purchasing and selection of low-sodium food with the children' for P, and on 'way of selecting restaurant menu' for OW. Also the program included 'way of choosing the low-sodium foods when eating out' with suggestions on sodium content of the dishes and snacks. Further, 'dietary guidelines to reduce sodium intake' was also suggested to help self-regulation. Conclusions: This nutrition education program and education materials could be utilized for the community education and provide the basis for further consumer targeted education program for reducing sodium intake.

Polycyclic aromatic hydrocarbons (PAHs) are well known for strong carcinogen. However, the human exposure analysis of PAHs is quite difficult and unreliable because of hard for estimation of actual expose dose. Then urinary 1-hydroxypyrene (1-OHP) has been a biological marker of exposure to PAHs. The purpose of this study was to investigate total amount from exposure to PAHs soused by indoor occupational exposure, and residence at Seoul metropolitan area and Kyeonggi province in Korea. Thirty-five housewives were included in this study from April 2003 through February 2004. Dietary habit and general characteristics such as age, type of building, existence of passive smoking, period of residence, fuel type for heating and ventilation type were obtained by self administered questionnaire. Urine samples were collected at morning and freeze quickly. Urinary creatinine was measured for converting into 24 hr urine. Concentration of the indoor PAHs was examined by NIOSH method number 5506. Urinary 1-OHP and PAHs were analysed by HPLC. Correlation coefficient between urinary 1-OHP levels and pyrene concentration of indoor air was 0.66 and statistically significant(P<0.01). The difference of urinary 1-OHP level due to dietary habits were not significant. Urinary 1-OHP level of Spring, Summer, Autumn, and Winter were $0.21{\pm}0.12,\;0.10{\pm}0.17,\;0.16{\pm}0.12,\;0.17{\pm}0.14{\mu}g/g$ cr, respectively. The arithmetic means of urinary 1-OHP for four season tee $0.16{\pm}0.14 {\mu}g/g$ cr. There was a trend that urinary 1-OHP level of residents who dwelling in apartment were higher compared with detached home, Comparison of 1-OHP level between heating by kerosene and LPG, Much higher gas heating type than kerosene type (P<0.05). This result implies that the urinary 1-OHP can be applied as the PAHs exposure indices.
