Objectives: With the increasing number of single households and so-called Honbab-jok, those who eat alone, people tend to enjoy convenient and simple meals, such as single dish meals. This study was performed to provide data on the energy and nutrient content, and nutritional adequacy of single-dish meal. Methods: From the literature reviews, 61 types of single-dish meals were selected, and divided into 4 groups (steamed rice, noodle, porridge, and sandwich burger), and a further 11 sub-groups (bibimbab, fried rice, topped rice, rolled rice/ warm noodle, cold noodle, seasoned noodle, dukgook/ porridge/, and sandwich, burger). In addition, 382 junior high school students from Gyeonggi, Sejong, Jeonbuk, and Chungnam areas were recruited for the survey. The survey questionnaires were composed of the characteristics, preference, and intake frequency of single-dish meals. The representative energy content (arithmetic mean) of single-dish meals were calculated, and compared with the energy contents of preference and intake frequency-weighted values adjusted. The representative nutrient contents, energy contribution ratio, and INQ (index of nutritional quality) of a single-dish meal were calculated for a nutritional adequacy evaluation. Results: The study subjects considered a single-dish meal as tasty, simple and fast to prepare, inexpensive, nutritious, and no low calorie food. The preference scores of all but 1 sub-group of singledish meals were ${\geq}5.00$ (5.00~5.97), and 1 sub-group (porridge) was 4.67 on a 7-point scale. The intake frequency of 11 sub-groups were 0.31~1.71/week, porridge was the lowest at 0.31 and warm noodles was the highest at 1.71. Fried rice, rolled rice, and warm noodle' intake frequency were ${\geq}1/week$. The representative energy of steamed rice, noodle, sandwich burger were 443, 429, and 428 kcal, respectively, and that of porridge was 264 kcal. Less than 5% differences in the representative energy of 4 groups were observed when adjusted for the preference or intake frequency-weighted values. The energy contribution ratio of macro-nutrients calculations showed that porridge was a high carbohydrate and low fat food, whereas sandwich burger were high fat and low carbohydrate foods. The INQ of calcium and vitamin C were less than 1.0 in all 4 food groups, but the INQ of protein and thiamin were > 1.0 in all 4 single-dish food groups. Conclusions: The representative energy in the 4 groups of single-dish meal was 264~450 kcal, which is a rather low calorie meal, and the energy contribution ratio of macro-nutrients were inadequate. The protein and thiamin levels were sufficient but the calcium and vitamin C levels were insufficient in all 4 groups of a single-dish meal judged by the INQ. The additional intake of fruits and milk dairy products between meals with a single-dish meal, supply of calcium and vitamin C may increase, which will result in an improved nutritional balance.

The objectives of this study were to explore hospital foodservice management and to investigate conditions related to health insurance coverage of inpatient meals. A questionnaire was distributed to the nutrition departments of 44 hospitals in Seoul on July 2009. The average kitchen area was 0.5 $m^2$, and centralized distribution systems were in place. Partition walls from contamination zones, separate work tables to prevent cross-contamination, exclusive areas for preparing tube feeding, and split carts with refrigerated and convection heat settings were largely used in tertiary hospitals. Most dietitians did meal rounds (93.2%) and surveyed for patient satisfaction (86.4%). The major theme of QI (Quality Improvement) was menu management (31.8%). The health insurance fees for meals were (won)4,938.9 for a general diet, (won)5,199.8 for a therapeutic diet, (won)4,067.0 for tube feeding, (won)9,950.0 for sterilized diet, and (won)18,383.4 for diets not covered by health insurance. The prices for general and therapeutic diets were significantly lower in hospitals compared to tertiary or general hospitals (P<0.001). The cost composed of 48.3% food, 44.0% labor and 7.7% overhead for general diets and 47.9%, 44.5% and 7.6% for therapeutic diets. In the case of health insurance coverage for patient meals, the number of items applied to general diets averaged 2.8 out of 4 and for therapeutic diets it averaged 1.9 out of 3. To reform the health insurance coverage system for patient meals, it is urgent that the qualified level of patient meals is presented from a national viewpoint, and monitoring should be performed consistently by developing the evaluation tools.

The purpose of this study was to investigate eating habits and patterns in accordance with the mental health status in Korea. Data from the fifth Korean National Health and Nutrition Examination Survey in 2010-2012 by the CDCP were used to target 19-year-olds. A total of 15,484 subjects (6,348 men and 9,500 women) were enrolled in this study. The collected data were analyzed using frequency analysis, cross-analysis, and multiple logistic regression analysis. The results revealed that men showed, with linear tendency, a decrease in stress and suicidal ideation with an increase in the number of meals. (p<.05). Women also showed, with linear tendency, that an increase in the number of meals resulted in a reduction of stress, depression, and suicidal ideation (p<.05). The stress level of women decreased by 0.667 times when they ate two meals rather than one time meal per day. If women ate three meals compared with one meal per day, stress, depression, and suicidal ideation were reduced by 0.522, 0.605, and 0.508 times, respectively (p<.05). It was found that Aa regular eating habit may have an impact on stress, depression, and suicidal ideation. Moreover, irregular meals, brought on by modern influences, could have a negative impact on mental health, leading to social and economic losses. These results suggest that we need to educate and promote awareness on proper eating habits.

The objective of this study was to investigate the dietary behavior and preference of vegetable food and to provide preliminary data required for menu promotion for middle school students' proper diet habits for their health. A survey was conducted for one week(2007) in Kyounggi province(Ansan and Seoul). The result was as follows. Three times a day was the highest in the number of eating meals and boiled rice. In the preference of food items, the meat food was more preferred than the vegetable food. In case of vegetable preference, males were higher than females. Many students recognized one dish of vegetable food in their meals. 72.4% of students ate less than provided in the food service system. Also, 7% of students did not eat vegetable foods entirely. They have had 1/2 dish(35.2%) of Kimchi in their meals and only 10.6% of students didn't eat Kimchi at all. The reason that students ate vegetable provided was 'for eating rice'(47%). Also, the reasons that students do not eat vegetable provided were 'bad taste' and 'unfavorite vegetable'. The above results indicated that it was needed to understand the importance of vegetables and education about the nutrients of vegetables.

The purposes of this study were to evaluate on the importance about the possible remedies for improvement of sanitation management by foodservice manager and to compare dietitians' opinion and that of administrators about theirs. A questionnaire survey was performed by 282 dietitians and 56 administrators, who were involved at foodservice facilities in Daegu and Gyeongbuk from March 7 to March 9 in 2007. According to the results of the importance evaluation analysis about the remedies for improvement of sanitation management, there were significant differences between dietitians and administrators in the means of 6 items such as "remodeling of hygiene equipment and facilities", "improvement of dietitians' food safety knowledge", "self-operated management of foodservice operation", "enforcement of cooperation between the CEO or administrators and dietitians", "development of food safety education program for foodservice workers", "increasing of foodservice operating budget". In all of them, the dietitians' evaluation scores were significantly higher than that of administrators. In addition, four factors were extracted by exploratory factor analysis. According to the results of one-way ANOVA, operating, education, and policy support sector showed that significant differences across type of foodservice, frequency of meals served, number of meals served per day, dietitians' education level and career. On the other hand, supervision sector showed that significant differences across number of meals served per day and dietitians' employment type. In conclusion, in order to increase the quality of sanitation in the foodservice operation, we should increase sanitation performance and enforce the food-safety education for foodservice workers. In addition, government should increase the policy support.

The purpose of this study was to investigate dietitians' needs of teaching materials about nutrition education for school children in Kyonggi and Chungnam(including Daejeon) areas. This study was carried out using questionnaires via e-mail or in class to the subjects of 166 elementary school dietitians as 68 in Kyonggi and 98 in Chungnam. The number of small(less than 700 meals), medium(700-1400 meals) and large(over 1400 meals) schools based on served meals daily were 48, 62 and 56, respectively. The results are as follows: Frequency of nutrition education for students as well as for teachers was samely very low as 'once per two months' and the education used to perform during lunch time mostly. For preparing nutrition education they obtained informations from the internet(64.0%). The main topics of nutrition education they used to covered were 'et's eat breakfast', 'table manners', 'the relations of body and nutrients', 'food waste', 'foods and calorie', etc.. The largest limit of nutrition education practices faced by school dietitians were pointed out as 'lacks of teaching materials' and 'counseling techniques'. Most dietitians wanted CD or substantial teaching materials for the practices, and required their contents covering 'cooking', 'food and calories', 'let’s eat various foods', 'relations of body and nutrients', 'regular meal is important’ and etc.. Since we expect nutrition teachers to be realized soon, nutrition education/counseling is emphasized more as their duty. Even though school dietitians revealed poor self-confidence, they were positive to get improved by reeducation of nutrition counseling methods and skills. If easy and suitable education materials(CD type) are developed as good as the school dietitians desired, the materials could contribute much to better nutrition education/counseling practices at schools.
