Purpose: The purpose of this study was to analyze the dietary intake of Korean adults with atopic dermatitis (AD) to determine whether the risk of developing AD was related to their diet. Methods: Among the participants in the 7th National Health and Nutrition Survey (2016 to 2018), 10,571 adults aged 19-64 were divided into AD (AD group, n = 366) and control groups (non-AD group, n = 10,205) to compare and analyze their nutrient intake status and Korean Healthy Eating Index (KHEI) score. Depending on the prevalence of AD, the nutrient intake, nutrient intake per 1,000 kcal, acceptable macronutrient distribution range, and KHEI score were tested for significance by correcting for age, sex, body mass index, education, marriage, occupation, residence area, physical activity, and energy intake variables that were derived for confounding factors. Results: The acceptable macronutrient distribution range for protein was lower in the AD group than in the non-AD group. Comparing the nutrient intake per 1,000 kcal, the intakes of protein, phosphorus, iron, and potassium of the AD group were significantly lower than those of the non-AD group. In the KHEI, the scores of total vegetables, vegetables excluding kimchi and pickles, meat, fish, eggs, and legumes of the AD group were significantly lower than those of the non-AD group. In addition, as these food intake scores increased, the risk of AD significantly decreased. Conclusion: In conclusion, adult AD patients had low intakes of vegetables, meat, fish, eggs, and legumes, and it was confirmed that high intakes of these foods may be associated with low AD risk. Therefore, we suggest that an adequate intake of vegetables and foods containing protein would be necessary for the management and treatment of AD in adults.

This research is intended to reveal the correlations between diabetes and dietary and other related factors. We were studied for 257 diabetics, in t도 9 general hospitals, located at Seoul, From August 109 to September 3, 1986. The result of this study can be follow ; 1) Distribution of the subjects according to their general characteristics ; The sex ration of the subjects is 1.06 ; 1.00 (male ; female), and the average age is 54.7 $\pm$10.9 years. Among the subjects 28.8% have a family history of diabetes ; the closer the genetic relationship, the more hereditory factors play a part. 2) Distribution of the scores according to their socioeconomic status ; As the socioeconomic status goes p, the intake of calories and fiber increases ; however, the frequency of eating out and the degree of physical activity decrease. 3) Relationship between obesity prevalence and each variable ; Among the subjects 27.2% are obese, and 60.3% have been obese in the past. Even though there is no significant relationship between the food habit and obesity, the number of people who are obese shows a significant increase as the socioeconomic status improves. 4) The effect of sex on each variable ; The intake of calories, sugar, alcohol and coffee is higher in male subjects, as is the frequency of eating out. In regular exercise and physical activity, there are significant differences between male and female subjects.

This study was performed to investigate the risk factors for coronary heart disease in elderly women. Seventy five elderly women over 65 years of age participated with 35 elderly men over 65 years of age, 40 middle-aged men and 31 middle-aged women as control subjects. The percentage of body fat(34.1 5.6%) in elderly women found to be significantly higher than in other groups and their waist/hip circumference ratio(WHR) was higher than in middle-aged women. The concentrations of plasma total cholesterol and LDL-cholesterol in elderly women were higher than in other groups, TG concentration higher than in middle aged women and HDL-cholesterol % lower than in other groups. Plasma cholesterol ester transfer protein(CETP) activities of elderly women were significantly higher than in middle-aged subjects, but were not different from those of elderly men. Plasma Apolipoprotein(Apo) A-I level in elderly women was higher than in middle-aged men but not different from the other groups. Differences among groups were not great in Lipoprotein (Lp)(a)levels. CETP activities were significantly correlated with age, body fat % total cholesterol, LDL-cholesterol and Lp(a). Therefore, it appears that the increased risk of coronary heart disease in elderly women is due to the increase of body fat, central adipose distribution, serum total cholesterol, LDL-cholesterol and CETP activities.

1. The effects of chloroform to the tissue lactic dehydrogenase (LDH) activities and its isozymes and to the tissue glutamic dehydrogenase (GDH) activities and its isoaymes are studied using the experimental albino male adult rats in this paper. The tissues studies are liver, kidney, heart, and brain. Besides the control group, two experimental groups are studied providing succeedingly 4 days interpariental administrations of chloroform, 0.0025ml and 0.025ml per day respectively. The changes of body weights, weights of organs, activities of GDH and LDH and their isozymes of each tissues, are analysed. 2. The body weights of rats are decreased due to the chloroform administration. 3. There are no significant differences of weights of organs due to the chloroform administration. 4. The significant decreases of tissue GDH activities and the significant changes in percent distribution of the GDH isozymes are found due to the chloroform administration. This weight be interpretated that chloroform effects to the protein and amino acid metabolism of rats. 5. Due to the chloroform administration, the significant changes in tissue LDH activities and in percent distribution of tissue LDH isozymes indicating the decreases of $LDH_1$ which is the aerobic heart type and the increase of $LDH_5$ which is the anaerobic muscle type, are observed. This could be estimated that chloroform effects to the carbohydrate metabolism, particularly to the anaerobic glycolysis of rats.

This study was designed to estimate the improvement of Validity for food frequency questionnaire(FFQ) by offering multiple choice portion size in developing a questionnaire. Validity of the two methods(food frequency questionnaire I=FFQ I & Food frequency questionnaire II=FFQ II) was tested in comparison with reference method of the 7-day weighed record(7DWR). Dietary consumption data of the three methods(FFQ I, FFQ II & 7DWR) were collected from 101 female university students for the analysis. Validity was measured in two categories : One was the nutrient intake value from the three methods, the other was the identification of between individual variation within the group. Spearman's rank order correlation test and distribution graphs were used for the analysis. The result showed that individual intake value of the FFQII was closer to that of the 7DWR than that of the FFQ I.Spearman's rank order correlation between the FFQII and the 7DWR did not show any improved correlation. The distribution graphs of nutrient intake derived from both the FFQ I and the FFQII were different from that of the 7DWR. Therefore, it could be suggested that single one portion size food frequency questionnaire is an equally efficient method as a multiple choice food frequency questionnaire to be adopted in epidemiologic studies.

To investigate the effects of exercise-training on serum lipids, fat distribution and several parameters of body fatness(percent body fat, skinfolds thickness, body circumference) were assessed in 24 healthy male subjects submitted to an 8-wk high intensive exercise-training. Blood sample was taken twice, per and post exercise-training, Exercise-training took place 5 days a week and daily energy intake and expenditure were observed. The results obtained are summarized as follows: 1) Through exercise-training body weight (changes : 1.1$\pm$1.1kg ; p=0.000) and percent body fat (changes : 2.4$\pm$1.3% ; p=0.000) decreased significantly . 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$1.7mm and 0.2$\pm$1.9mm. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) Total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly changed by exercise-training while only triglyceride decreased (changes : 20.7$\pm$44.8mg/dl ; p<0.05). Changes in body weight were grately related to changes in total cholesterol. Changes in deep abdominal adipose tissue were related to changes in triglyceride.

Conditions for sufficient and rapid distribution of a cryoprotectant (sorbitol solution) into intact fish muscle (Oncorhynchus mykiss) were studied as changing in the residual Ca2+ ATPase activity during freeze/thaw cycling. Chunks of the fish muscle were immersed in 4 concentrations of sorbitol solutions ($20\%$, $30\%$, $45\%$, and $60\%$) by a shaker mechanism at 5$^${circ}C. Whole immersion samples (W) showed a higher value of the residual Ca2+ ATPase activity than those in the untreated controls (C), except in the treated controls (TC), while less effect of immersion concentration could be found. Comparing the extent of penetration of sorbitol into the surface layer to inner layer of immersed fish chunks, outer portion samples achieved excellent cryoprotection with $100\%$ of the residual ATPase activity values or more. For the inner portion samples, $30\%$ and $45\%$ sorbitol solution treatments indicated a higher ATPase activity than $60\%$ treatment. At high concentrations, mass transfer rates during osmotic dehydration might berapid and it causes faster surface drying by dewatering at surface solute layer. Periodically immersed and relaxed samples, W (5-3-1), led to good cryoprotection effect: W (5-3-1) indicated high residual Ca2+ ATPase activity values and the residual ATPase activity values excess $100\%$ in immersion of $30\%$ and $45\%$ sorbitol solutions.

This study measures patients' meal satisfaction according to the type of operation (self-operation and contract operation) and identifies improvement areas. A survey was conducted using 183 contract operation patients and 60 self-operation patients receiving general meals. The mean score for satisfaction for the whole sample was 3.42 (self-operation = 3.51; contract operation = 3.39), and self-operation satisfaction was significantly higher than contract operation satisfaction. Mean scores were 2.98 for food, 3.26 for menu composition, 3.57 for sanitation, 3.78 for distribution meal services, and 3.50 for menu information. Self-operation showed a higher satisfaction level than the contract operation in food and menu composition. The ccontract operation showed a higher level of satisfaction than self-operation in sanitation, distribution meal services, and menu information. In terms of feeling dissatisfaction with meal services, both groups showed the highest dissatisfaction with food and menus, and both groups agreed on food and menus that required the greatest improvement. Based on the results, contract operation managers should develop and apply menus considering their preferences. Dietitians of self-operation strengthen communication between meal service staff and patients by carrying out periodic and systematic service education on self-operation.

The objective of the current study was to compare the execution of hygiene and safety management according to the characteristics of children's food service stations, with the ultimate objective of providing sanitary and safe food service to children. To this end, the study conducted surveys of 73 public and private pre-schools with fewer than 100 children in district A from July 30 to October 31 2015. The differences were evaluated by t-test and analysis of variance. The confidence and validity of the results were analyzed by six food ingredient and facilities management questions, three personal hygiene and facilities management questions, four environmental management questions, and five storage and treatment management questions; for a total of 18 questions. The cumulative distribution of the four factors was 61.569%, and the Cronbach's alpha was 0.821, which indicated that the results were reliable. The results revealed that public pre-schools (a) and home-based pre-schools (b) had different levels of food ingredient and facility management, but no differences in the number of cooks, number of children served, type of food distribution, and the existence of mass food service facilities. The results of the study may be used to develop hygiene and safety management manual and educational contents to promote the health of the children served.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.
