This study investigated the perception of employees in restaurants located in Seoul concerning climate change, food safety against climate change and performance of food safety management. The survey was administered to 535 respondents from June 10~13, 2013. Exactly 52.2% of respondents answered that knew of climate change, whereas 7.3% of respondents answered that they didn't know about climate change. 86.6% of respondents recognized that climate change affects food safety. Among food safety management performance, the highest score was observed for thoroughly cooked foods (more than 1 min at $74^{\circ}C$ as internal temperature of foods). For importance of role of operator, respondents recognized that 'confirming food safety guideline' and 'cleaning and disinfecting environment' were important. For 'whether have you seen the food safety guideline against climate change', 32.5% said 'yes' while 67.3% answered 'no' or 'don't know'. Based on these results, employees in restaurants generally recognize climate change and its relationship with food safety. However, food safety education and related guidelines need to be improved to provide related information.
This study was carried out to examine information regarding nutritional intake according to intake of health improving agents. For this study, 593 adults were interviewed face-to-face. The average ages of the participants were 58.8 years old in males and 56.1 years old in females. The percentage of individuals taking agents was significantly higher (p<0.05) among the females (22.1%) than the males (14.1%). Men showed a preference for taking animal protein bases restorative food and health supplements, while women preferred health supplements and nutritional supplements as improving agents. However, there were no significant differences between the two groups. The total daily food intake was also not significantly different according to intake of improving agents in the male and female groups. The male subjects who took improving agents showed significantly lower intake of potato and starches, pulses, fungi and mushrooms, seaweeds, oils and fat, as well as seasoning than those of non-users. Female subjects who took these agents also had a significantly lower intake of pulses, nuts and seeds than nonusers. No difference in the daily energy intake was reported in male and female groups whether the individuals were taking improving agents in male and female groups or not. However, in male subjects who took improving agents, there was a significantly lower intake of protein, dietary fiber, carotene, vitamin $B_1$, folate, vitamin C, vitamin E, plant calcium, potassium and plant iron than the male non-users. This study suggests that practical education be emphasized for proper nutrition intake thorough nutritional management according to improving agents.
The aim of this study is to investigate the effects of hot water soluble extract from green tea on the components of serum and the liver and the antioxidative effects in accordance with the different protein types. For this purpose, four experimental groups were set up. As for the protein source casein, isolated soy protein was supplemented to the rats, together with hot water soluble extract from green tea. Four experimental groups kept eight Sprague-Dawley rats respectively. The CP group was supplemented with casein only, the CG group was supplemented with casein and hot water soluble extract from green tea, the ISP group was supplemented with isolated soy protein only, and the ISG group was supplemented with the isolated soy protein with hot water soluble extract from green tea. After 4 weeks of feeding with experimental diet, the levels of serum and liver lipid and antioxidant enzyme activity and TBARS in the liver were measured. The results are; 1. Weight gain and FER were higher in the casein group than in the isolated soy protein group in general. In the casein group, the weight gain and FER were reduced significantly when hot water soluble extract from green tea was supplemented (P < 0.05). There was no significant difference in feed intake. 2. In general, total cholesterol and LDL-cholesterol in the serum were higher in the casein group than in the isolated soy protein group, however just the concentration of LDL-cholesterol in the casein group was significantly lower when the hot water soluble extract from green tea was supplemented (P < 0.05). 3. Triglycerides in the liver were higher in the casein group than in the isolated soy protein group general, however when hot water soluble extract from green teas was supplemented only in the isolated soy protein group, the content of triglyceride in liver was significantly lower (P < 0.05). 4. There was no significant difference in antioxidant enzyme activity in the liver in all the groups, however the content of TBARS was low only in the casein group when hot water soluble extract from green tea was supplemented (P < 0.05).
This study was to investigate the consumption pattern and nutrition knowledge about vegetables of 184 housewives attending the school of adult and continuing education attached to DukSung Women's University. The results were summarized as follows; the average vegetable expenses were $10,000{\sim}20,000$ won per week. The frequency of purchasing vegetables was $2{\sim}3$ times a week. Respondents usually bought the vegetables at local markets and supermarkets. As for buying vegetables, all of respondents kept in mind all the time the organic vegetables were better. The price was the most important factor of their purchase in the low income households. In the family, the vegetable dishes were favored by housewives most and by sons least. Among the vegetable cooking methods, Kimchi was the most frequently used and salad was the least. Forty four percent of the respondents experienced purchasing ready made vegetable dishes in the market. The reason they bought ready made ones was the special taste of the dishes. The rest of respondents never bought cooked vegetable dishes because they thought the dishes unsanitary. Twenty seven percent of the respondents experienced purchasing. The reason for not purchasing Kimchi was the housewives' traditional prejudice of buying Kimchi in the market. Respondents have a considerable knowledge that 42 kinds of vegetables could be good for certain disease and 10 kinds of vegetables might be harmful for certain disease.
We carried out a validation-calibration study of the food frequency questionnaire (FFQ) that we had previously developed for a community-based cohort of the Korean Genome and Health Study of the Korea National Genome Research Institute. We have collected a total of 254 3-day diet records (DRs) from 400 subjects, 200 each randomly selected from the two study cohorts of Ansung and Ansan. FFQ was administered at the time of cohort recruitment in 2001, and DRs were collected during a two month period from January through February of 2002. The mean age was 52.2 years. Farming for men and housewife for women were the most common occupations. The majority of the subjects had undergone 6∼12 years of education. The general characteristics including demographic and other data were not different from the total cohort subjects. Absolute levels of consumed nutrients including total energy (energy), protein, fat, carbohydrate, calcium, phosphorus, sodium, potassium, iron, retinol, carotene, vitamin A, thiamin, riboflavin, niacin and vitamin C were compared. The average of energy intake was not significantly different between the data collected by the 2 methods. However, consumptions of protein and fat were higher in data of DRs, whereas that of carbohydrate was higher in FFQ data. Significant correlation of each nutrient consumption between the data sets was observed (p < 0.05) except in the case of iron, while the average correlation coefficient between them was 0.22 ranging from 0.33 for energy to 0.11 for iron. The results of cross classification by quantile for exact classification ranged from 25.2% (carotene) to 35.0% (phosphorus), and from 64.6% (vitamin A) to 76.4% (retinol) for adjacent classification. The proportion of completely opposite classification was 8.1% in average. Calibration slope was estimated by regression and calibration parameters ranged from 0.025 for carotene to 0.423 for niacin. We conclude that the FFQ we have developed is an appropriate tool for assessing the nutrient intakes as ranking exposures in epidemiology studies in view that amounts of consumed nutrients obtained by FFQ were similar to those collected by DRs, that correlations between consumed nutrients collected by these methods were significant, and that classification results were relatively fair. The correlation coefficients, however, were lower than expected, which may be mainly due to the survey season. In fact, any short-term dietary survey cannot accurately reflect the overall dietary intakes that change heavily depending on seasons. Further studies including the analysis of chemical indices would be helpful for the studies of causal relationship between the diet and disease.
Small amounts of trans fatty acids exist naturally in beef and dairy foods. Also, they can be produced in the process of partial hydrogenation to manufacture shortning or margarine. They can provide a better palatability and shelf life. According to the recently studies, trans fatty acids can raise health risk such as heart diseases and coronary artery diseases. They can also increase low-density lipoprotein (LDL) cholesterol and decrease high-density lipoprotein (HDL) cholesterol in the blood plasma, therefore increasing the risk of atherosclerosis and diabetes. The aim of this study was to determine total lipids and trans fatty acids (TFAs) content in processed foods and meat products. The analysis of trans fatty acids was performed in 28 samples of donuts, 18 samples of bakeries, 4 samples of frozen doughs, 2 samples of popcorns, and 4 samples of meat products (ham, sausage, nuget, and bacon). Total lipids in processed foods and meat products were extracted by chloroform-Methanol method and acid digestion, respectively. They were analyzed by gas chromatography using a SP-2560 column and flame ionization detector. The amounts of TFAs per 100 g of foods were 0-3.3% (0.74% on average) in donuts, 0.2-5.8% (1.18% on average) in bakeries, 0.2-6.3% (1.93% on average) in frozen doughs, and 0-5.8% in popcorns. Meat products such as ham, sausage, and nuget analyzed 0.1% of TFAs, respectively and trans fatty acids in bacon were not detected. As a result, the distribution of TFAs in processed foods was widely ranged from O% to 6.3% according to manufacturers and types of products, whereas the content of TFAs in meat products ranged from 0% to 0.1%.

The purpose of this study was to investigate the effect of alcohol drinking on dietary behaviors and nutrient intakes among the university male students. The subjects were divided three group; no-alcohol group(n=83), alcohol group(n=78), and high-alcohol group(n=78).And they were observed general characteristics, life style, eating pattern, food frequency and nutrient intake using questionnaires. The mean age, height, weight and BMI of the subjects were 25.8$\pm$6.1 years old 171.5$\pm$5.4 cm, 63.4$\pm$9.7 kg and 2.3$\pm$2.8/kg/$m^2$, respectively. The types of residence and person who prepares meals were significantly different among the groups: the frequency of self-boarding and preparing meals oneself in high-alcohol group were higher than in other two groups. The frequency of physical exercise and cigarette smoking in high-alcohol group were higher than in other two groups. There were no significant differences in skipping meals among three groups. However, the most common reson why high-alcohol group skipped meals was due to a eating habit, while a lack of time in other two groups. The results show that the high-alcohol group tended to eat more often instant ramien, soybean sprout, anchovy, and coffee compared to the other two groups. The energy intakes in alcohol and high-alcohol groups were lower than those in no-alcohol group. In conclusion, high-alcohol students have unhealthy dietary behaviors in the light of high frequency of cigarette smoking, eating habit of skipping meals and instant foods, and therefore showing a strong need of proper education in alcohol withdrawal and meal management for them.

Objective : The aim of this study was to identify subgroups of older adults with respect to their lifestyle patterns and examine the characteristics of each subgroup in order to provide a basic evidence for improving the health and quality of life. Methods : This cross-sectional study was conducted in South Korea. Community-dwelling older adults (n=184) above the age of 65 years were surveyed from April 2019 to May 2019. This study used latent profile analysis to examine the subgroups. Chi-squared (χ2) and multinomial logistic regression measures were then used to analyze individual characteristics and influencing factors. Results : The pattern of physical activity which is one of the lifestyle domains in elderly was categorized into three types: 'passive exercise type (31.1%)', 'low intensity exercise type (54.5%)', and 'balanced exercise type(14.5%)'. Activity participation was divided into three patterns: 'inactive type (12%)', 'self-management type (61%)', and 'balanced activity participation type (27%)'. In terms of nutrition, there were only two groups: 'overall malnutrition type (13.5%)' and 'balanced nutrition type (86.5%)'. Furthermore, as a result of the multinomial logistic regression analysis to understand the effects of lifestyle types on the health and quality of life of the elderly, it was confirmed that the health and quality of life were higher in those following an active and balanced lifestyle. In addition, gender, education level and residential area were analyzed as predictive factors. Conclusion : The health and quality of life of the elderly can be improved when they have balanced lifestyle. Therefore, an empirical and policy intervention strategy should be developed and implemented to enhance the health and quality of life of the elderly.

This study examined the health status and relative factors of 468 people of the latter stage of more than 75-year-old in 2011 the Korean National Health and Nutritional Examination Survey. The subjective health status were influenced significantly by sex(OR=0.456, 95%CI=0.257-0.805), occupation(OR=1.437, 95%CI=0.963-2.149), spouse(OR=0.673, 95%CI=0.443 -1.022), degree of stress(OR=0.476, 95% CI=0.309-0.730), depression(OR=0.410, 95% CI=0.238-0.704), subjective oral status(OR=1.874, 95% CI=1.332-2.643), smoking(OR=0.738, 95% CI= 0.523-1.039), drinking(OR=1.251, 95% CI=1.017-1.540), and waking practice(OR=1.698, 95% CI=1.188 -2.431). The results suggest that health education of active participations and publicity policies should be established and help improve the subjective health status in the latter stage of a 75-year-old.
The aim of this analysis was to investigate the relationship between the level of safety behavior and the level of oral health behavior among Korean children. Data used in this analysis were from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES). A representative sample of 4,292 children aged from three to eleven years who completed both health interview and health behavior survey. Simple and multiple logistic regression analyses were conducted. All analyses were weighted and SAS 9.1 survey data analysis procedures were used to estimate standard errors accounting for the complex sampling design of the KNHANES. More than seventy percent of children did not keep general safety behaviors except seat on back seat in a car. About seventy five percent of children had experience of preventive oral care during last one year, but about fifty six percent of children brush their teeth twice a day. Socioeconomic status and health behaviors were significantly related in three to six old age group only (p<.05). Generally significant relationship was not found between general safety and oral health behaviors. Among Korean children, general safety and oral health behaviors might be not related each other. Education for general safety behaviors should be underlined for all children. Especially preschool-children with low socioeconomic status need to be educated for healthy behaviors.
