This study was carried out to investigate the relationship between the food and nutrient intake status and eating-out practices of college students. A dietary survey of 361 subjects living in urban areas was conducted by using a 3-day diet record method. The average ages of the male and female subjects were 22.0 and 20.6 years old, respectively. Monthly personal expenses of the male and female students were 316,517 won and 296,888 won, respectively. 43.1% of the male and 50.8% of the female students used between one-quarter and one-half of their monthly personal expenses for eating out. Sixty-five percent of the total subjects ate out more than five times a week The average daily total food intake was 1630.7g in the males and 1453.9g in the females. The average percentage of total food intake from eating out (by weight) was 60.6% in the males and 56.2% in the females; foods eaten out were mainly potatoes, meats, processed foods, and beverages. It was found that 40-65% of daily total nutrient intake came from food eaten out. When they ate out, the male students ate slightly higher amounts of protein, fat and vitamin B1, while the female students ate relatively higher amounts of animal protein, fat, vitamin A and cholesterol. The more the subjects ate out, the more the quantity of total food intake increased. This increase resulted from high intakes of beverages and processed foods in the males, while the increase was from total plant foods, mushrooms, beverages, and milk and dairy products, in the females. The dietary variety score (DVS) was significantly increased in the female subjects when they ate out more than once a day; otherwise, the DVS was not significantly different between any of the male and female groups. The intakes of energy, and of many nutrients such as protein, fat, carbohydrates, calcium, phosphorus, iron, potassium and cholesterol, were increased when the female subjects ate out more than twice a day. The mean adequacy ratio (MAR) was at its highest level of 0.65 in the males when they ate out less than once a day, and at its highest level of 0.67 in the females when they ate out more than twice a day.

The purpose of this study was to develop curriculum of the elementary, and secondary school home economics that integrates three systems of action and to prepare a plan for convergence education in home economics curriculum. To achieve this goal, the characteristics of elementary, secondary school dietary curriculum integrating three systems of action, the focus of development, core competencies, and goals were derived through the review of literature. In this study, we set up perennial and sub-practical problems and selected content elements. The contents system of the developed curriculum was modified and supplemented by examining the validity of experts, and the achievement standard of the middle school home economics dietary education curriculum was developed by integrating the three systems of action. The content system of the elementary, and secondary school home economics curriculum that integrated the three systems of action is centered on practical problems, and the perennial problem is 'What should we do to practice healthy dietary life?' There are five areas of this curriculum: 'health and diet', 'food planning', 'food purchase and management', 'cooking', and 'meal', and the scope of curriculum is repeatedly expanded to 'personal and family', and 'social'. The practical problems in the five areas are composed of 10 practical problems in the two dimensions (personal & family, and society), and the practical problems and contents elements are spiralled by applying the principle of integration. The contents of this curriculum were compared with the achievement standards and learning elements of the dietary life in the 2015 elementary school practical arts, middle and high school 'technology & home economics', and the 'home economics science' curriculum. The results showed that the developed curriculum encompassed additional content beyond all the content already included in the 2015 revised curriculum.

Korean diet is high in plant foods but also high in salted vegetables. World Cancer Research Fund (WCRF) recommends consumption of fruits and vegetables excluding salted vegetables for prevention cancer. This study aimed to analyze relations between intakes of salted and non-salted vegetables and socioeconomic factors, providing a data for targeted groups in promotion of fruits and vegetables consumption. Dietary and socioeconomic status data of the 5,400 subjects over 30 years of age from the 2005 Korea National Health and Nutrition Examination Survey (KNHANESIII) were used. Dietary intake data from KNHANESIII was obtained by one day 24-hour recall method. Mean daily intakes of salted vegetables, non-salted vegetables and fruits of subjects were 151 g, 237 g, and 71 g respectively. Mean daily intake of salted vegetables was significantly higher in men than women for daily amount (173 g vs. 133 g) as well as percentage of total food intake (9.9% vs. 9.6%). Subjects living in rural area consumed more salted vegetables. Salted vegetables as percent of total food were lower in subjects with higher education levels (p < 0.001). Intakes of non-salted vegetables were significantly affected by age and gender. Intake levels of fruit were significantly higher in younger groups, in females, and subjects with higher income and education levels (p < 0.05). Average intake of fruits and non-salted vegetables was 307 g, lower than WCRF recommended level of 400 g for personal guideline. Intake of salted vegetables was positively correlated with sodium intake (Pearson's correlation coefficient, r = 0.43) but less so with potassium (r = 0.16) and other micronutrients intake (r < 0.1). On the other hand, non-salted vegetables had higher correlations with potassium (r = 0.45), carotene (r = 0.38), vitamin A (r = 0.37), iron (r = 0.34) and low for sodium (r = 0.13). Fruits intake was highly correlated with vitamin C intake (r = 0.46). Proportion of subjects satisfying WCRF personal guideline of fruits and non-salted vegetables was 25.7%. Results of this study indicate that intake of salted vegetable is considerably high among Koreans, and it is highly correlated with sodium intake and less so with other micronutrients.

Purpose: This study was undertaken to examine the perception of Korean consumers regarding soybean meat. Using the Dietary Identify Questionnaire (DIQ), the data obtained were analyzed to identify various factors related to a plant-based diet. Methods: A consumer survey was conducted from June 1^st to 30^th, 2021, targeting 260 Korean consumers over the age of 20 years. Subjects were asked to answer six questions related to the perception of soybean meat. Of the 52 items present in the DIQ, 33 items were verified and reconstructed. All data were analyzed using the SPSS statistics (ver.25). Results: The subjects were divided into two groups, 'passive consuming group' and 'active consuming group', based on their perception of soybean meat. Demographic analysis according to the perception of soybean meat showed significant differences in age, marital status, academic background, and family members. The DIQ was categorized into 7 types: prosocial motivation, out-group regard, centrality, public regard, personal motivation, strictness, and private regard. Comparing by perception about soybean meat, significant differences were obtained between both groups for 'prosocial motivation (p < 0.01)', 'centrality (p < 0.01)', 'private norm (p < 0.05)', and 'personal motivation (p < 0.001)'. The 'passive consuming group' showed relatively low scores in all 4 factors. Conclusion: In the future, the results of this study can be applied to define the meaning of vegan in Korea. We believe our results will provide basic marketing data for the plant-based meat market. This will help expand the soybean meat market for a sustainable life for consumers, which is based on various needs such as health and the environment.

The purpose of this study was to provide basic data necessary for creating a more successful health enhancement program, health education and health policy which can enhance health management abilities and enable a healthy school life by examining relations between high school students' health perception, who are in early adolescence, and their health promotion behavior. The subjects in this study were 813 students from 8 high schools on Jeju Island. The collected data were analyzed with t-test and one-way ANOVA through questionnaires by researcher on the basis of advance research. The findings of this study were as belows : 1. When general characteristics were considered, health perception was more significantly affected by those who were boys, whose family income was on a higher level, who scored better in school, whose parents were more concerned about their children's health, and who had experiences of being hospitalized. Especially, the more parents were concerned about their children's health, the higher the child's self-confidence on health(p<.05), anxiety on health(p<.05), practicality on disease prevention(p<.05), self-confidence on future health(p<.01), health care ability(p<.01), and family roles on health(p<.05). The less parents were concerned about their children's health, the higher the child's anxiety on disease(p<.01) and uncertainty on future health(p<.01). 2. When students' health promotion behavior was concerned, in the area of Eating Habits, having regular meals(72.9%), moderate consumption of meat(89.7%) and a balanced diet(64%) were common, whereas having a regular breakfast(37.4%) and eating vegetables and fruits(43.6%) were rare. In the area of Exercise, all subareas such as exercising 3 or 4 times a week(76.7%), more than one hour of exercise at a time(74.9%), a short distance walk(51.8%), exercise within one hour after meals(87%), and whether wanning up or not(88.6%) were above average. In the area of Personal Hygiene, all subareas such as drinking boiled water(57.3%), washing hands after using the bathroom(71%), brushing teeth after eating(42.4%), washing up after going out(50.3%), and washing hair and taking a frequent bath(77.2%) were rare. In the area of Control of Personal Relations, consulting personal problems with family(78.7%) had a positive response, whereas meeting someone new(59.8%), maintaining sound relations with the opposite sex(47.3%), having respect for one's opinion(51.5%), and maintaining peaceful relations with people(58.4%) had rare negative results. In the area of Stress Management, not being competitive(69.4%), releasing problems(62.4%) and sleeping soundly(66.2%) were common, whereas having your own ways to relieve stress(46.8%) and having your own dreams and hopes(58.5%) were rare. 3. When general characteristics were considered, as far as relations of health promotion behavior were concerned, the boys were significantly different in the area of Eating Habits(p<0.01) and Exercise(p<0.01), and the girls were in the area of Personal Hygiene. As family economic status was high and parents were concerned about their children's health, the entire areas of health promotion behavior were significantly different. Whether or not they were hospitalized made no significant difference in statistics. 4. When their regions were considered, it comparing city to town, there was no statistically significant difference in health perception and relations of health promotion behavior according to general characteristics. As seen in the results above, high school students' level of health perception and level of practicing health promotion behavior were generally low. In conclusion, by enhancing health perception, a plan for activating health education, which can implement positive health promotion behavior, should be made.

Objective: The purpose of this study is to identify the incidence risk of cardiovascular disease (CVD) in the workplace, and to suggest the prediction models for level of CVD incidence risk. Background: CVD can be caused by various factors related to personal habits such as diet and exercise, or genetics. However it can also be caused and aggravated by work, making the elimination of such risk factors at work crucial disease (KOSHA, 2013). Method: The distribution of CVD risk assessment levels of 162 workers was compared with the acquired medical examination data to discuss the necessity of assigning additional risk factors. Two alternative risk assessment models were given to enhance the accuracy of the evaluation; adjusting risk scores given in the KOSHA GUIDE H-1-2013 (alternative 1) and building a matrix of KOSHA GUIDE H-1-2013 and risk assessment results based on work condition levels (alternative 2). To verify the suggested models, medical examination results of 12 workers approved of convalescence were referred to. Results: The second alternative showed more relevance between the results and workers approved of convalescence in predicting the risk group when applied to actual heath examination data from the approved workers. The power of description of the new method for determining the risk of CVD incidence, 83.3%, is higher than that of KOSHA GUIDE H-1-2013, 25%. Conclusion: Results of this study imply that more approved workers had been from unmanaged normal groups than managed risk groups, raising the importance of CVD management. Application: The new prediction model considering working time and shift work developed in this study is expected to be a fundamental data for risk analysis and management of CVD in the workplace.

The effect studied was that of the feeding of shrimp by-product meal, as a source of eicosapentaenoic and docosahexaenoic acid, on growth performance and fatty acid composition of adipose tissue in growing pigs kept on small holdings in Central Vietnam. Shrimp by-product meal was exchanged with ruminant meal so that the diets contained either 0, 10 or 20% shrimp byproduct meal in the dry matter. The diets were fed on 6 different small-holder farms. The farmers fed a base diet according to their personal choice, but were instructed as to the use of shrimp by-product and ruminant meal. The diets were fed to the pigs from 70 to 126 days of age. There were three animals per treatment group per farm. The diets without and with 20% shrimp by-product meal on average contained 0.01 and 0.14 g docosahexaenoic acid/MJ of metabolisable energy (ME). Due to the higher contents of ash and crude fiber, the shrimp by-product meal containing diets had lower energy densities than the control diets. Eicosapentaenoic acid was not detectable in adipose tissue; the content of docosahexaenoic acid was generally increased after consumption of shrimp by-product meal. In spite of the concurrent high intakes of ash and crude fiber, the feeding of shrimp by-product meal had a general stimulatory effect on growth performance of the growing pigs. The intake of docosahexaenoic acid or its content in adipose tissue was not related with average daily gain. It is suggested that shrimp by-product meal may contain an unknown growth enhancing factor.

This study was designed to provide data useful for the efficiency of dietitians' nutrition care by evaluating medical staffs' perception of nutrition in a hospital. The datas were collected through a questionnaire survey conducted upon 874 medical staffs at 50 general hospitals , each one with more than 100 beds, in Seoul and Pusan. A logistic regression analysis was used to determine the influential factors of medical staffs' perception about nutrition among the selected variables. As a result, most medical staffs(96.9%) had positive perceptions about the importance of nutrition as a medical therapy. However, more than half of the respondents(69.1%) said that the dietary department plays the auxilliary role of producing patients' meals according to diet prescriptions. 271% of the medical staffs perceived that the dietary department as contributor to patient's health care through involvement in medical nutrition therapy, while 4% of the medical staffs misunderstood the dietary department as part of the hospital administration. The results of logistic regression analysis showed that factors related to hospital size and dietitian manpower( Total No. of beds, No. of beds per dietitian) have more influence upon medical staffs' perception about nutrition than their personal and occupational characteristics(P (0.001). In case where medical staffs' perceptions were more positive, the efficiency of dietitians performing nutrition care was higher. Results of this study suggests optimal dietetics staffing as a way to increase the efficiency of nutrition care in a hospital.

The purposes of this study were: a) to develop the a quality measurement tool for the contract-managed hospital foodservice, and b) to evaluate their performance with the developed quality measurement tool, and c) to verify the reliability and validity of the quality measurement tool. The developed quality measurement tool comprised two parts, which were foodservice management and medical nutrition care service. The foodservice management part was classified into six functional categories which were Menu, Procurement and Storage, Production and Distribution, Facility and Utility, Sanitation and Safety, and Management and Evaluation. The medical nutrition care service part indicated the medical nutrition care provided. Quality measurement tool had 91 standards and 324 indicators. The quality measurement tools were distributed to the hospital foodservice manager employed by the foodservice company. The 324 indicators were measured by foodservice manager on the 5-Likert-type scales, and then adapted to a 100 point scale. The SPSS Ver. 11.0 was used for statistical analysis. The categories whose scores were evaluated as being high were Procurement', General Sanitation', Personal sanitation' and Waste' and the categories whose scores were evaluated as being low were Diet Order Manual', Standard Recipe', Appropriateness (Facility and Utility)', Check (Facility and Utility)'and Information Management'. All the categories of medical nutrition service were evaluated as having seriously low scores. Therefore, it was necessary for the contract-managed hospital foodservice to improve its performance in the area of medical nutrition care service. For the verification of the developed quality measurement tool, the reliability obtained by calculating Cronbach's α was 0.8747, and the content validity was also proved by scrutiny of the modification of the Professional group's techniques.
