The purpose of this study was to evaluate the menu of meal boxes delivered to low-income children during summer vacation. Out of 114 questionnaires distributed nationwide concerning lunch menus during summer vacation of 2008, 51 (44.7% response rate) were returned. A total of 170 daily lunch menus consisting of 5 day menus from 34 organizations (29.8% analysis rate) were analyzed after excluding 16 organizations that delivered side dishes only and one organization that provided menus of less than 5 days. The mean numbers of dishes and food items in the menus were five and eight, respectively. Over two-thirds (67.1%) of the lunch box menus included only three food groups: grain, meat and vegetable. Only 2% of the menus included all five food groups, grain, meat, vegetable, fruit, and dairy products. In general, the menus tended to lack fruits and dairy products; the percentages of the menus not including fruits and dairy products reached 89% and 77%, respectively. The average number of dishes, distribution of food group patterns, and average dietary diversity scores of the menus were significantly different according to reimbursement rate. The organizations receiving reimbursement of 3,500 won were more likely to include diverse food groups than those receiving 3,000 won although most of the menus were not proper in terms of food diversity anyway. These results suggest that lunch box menus for low-income children can be improved, in particular, by including more diverse food groups.

The main purpose of these studies was the improvemen of nutritional supply and of the future physical coditions. The two groups which were regional difference were chosen and research for the nutritional status of elementary school students. The nutritional status of lunch-box between one elementary School of 98 students in the 6th year grade(hence-forward it was called "A-Group"), located at the center of Masan City, being provided the milk and the other elementary School of 134 students in the 6th year grade(hence-forward it was called "B-Group"), located in the small farm and fishing villages of Kusan-myun, Euichang-kun, Kyungnam province, were seweyed from the period of Nov. 20, 1986 to Dec. 4, 1986 and conclusion were as follows: 1. Nutritional status of lunch-box 1) It is indicated that in the case of A-Group, the nutirtional intake except animal protein and vitamin A were lower than the Recommended Daily Allowances of Korenas and in the case B-Group, was also lower than except vitamin A respectively and especially in both groups, the percentage of Fe was lowest and intended difference between A Group and B was that B-Group in the intake of calorie, fat, Ca, Fe and etc were lower than A-Group. 2) The total calorie-intake was short of the extent to approx. 83.8% as compared to the RDA. On the viewpoint at ratio of intake of caloric nutrients, A-Group appeared to be 69.5 : 16.5 : 14 and B-Group, 77.5 : 19.5 : 13 in order carbohydrate, protein and fat. As a result of the above ratio, B-Group depended upon carbohydrate as a staple food more than A-Group. It can be considered that the total calorie-intake is short, and that the amount of lunch-box was greatly insufficient for taking optimal nutrition. 3) Calorie, carbohydrate, vitamin B, and niacin were taken nutrition from a staple food and protein from at similar ratio of staple and subsidiary food and fat, Fe, vitamin A, vitamin B1, adn vitamin C were mainly taken from a staple food. It was indicated that B-Group was higher at the supply-ratio by a staple food than A-Group. 3. The realities of improvement of physical conditions The improvement of physical conditions of the two groups were lower in accordance with Korea Children's Growth Standard, but B-Group was inferior to A-Group. 4. Seeing that the total intake of nutrition being taken at lunch time was lower as campared to the RDA intakes between the two Groups were remakably different, a lot of efforts should be made to improve the calorie-intake for the purpose of the farm and fishing villages. For balanced intake of nutrition, selection of foods and various cooking ways are important, therefore, throughout the expansion of the lowest stratum of elementary schools for milk-supply, high-quality protein, fat, Ca, vitamin B2 and etc should be supplied to the growing students. That can narrow the gaps of the intake of nutrition and physical condition between the students who live in cities and the students who live in the country.

We evaluated the nutritional status of 116 Songmyun middle school students. The means of height and weight were similar to the standards published by the Ministry of Education(1991). The height of 79% of the subjects was in the normal range, and the height for 11% was below the normal range. While 27% of the subjects were underweight, 18% and 8% were overweight and obese, respectively. The percentage of anemia was 29%, and the mean urinary urea nitrogen to creatinine ratio was 8$\pm$4. Total daily energy and nutrient intake was 48-103% of RDAs, and especially calcium and iron intake was very low. Carbohydrate, protein and fat intake was 71%, 12% and 17% of total calories, respectively. Breakfast, lunch, dinner and the between meals provided 20%, 37%, 26% and 18% of total energy intake. Energy and nutrient intake from lunch box was 52-95% of the 1/3 RDAs. Our data suggest that the nutrition education for the meal planners of the subjects is necessary to improve the nutritional status of the subjects. In addition, the school lunch program is recommended.

This study was projected to get basic data which can provide a basis for future direction in nutritional education, and also to find the way how to improve the nutritional supply by evaluating the current nutritional intake of average high school students through the survey study of their daily packed lunch. Five hundred twenty seven students from two boys high school and two girls high school including one general and one vocational school respectively were chosen as random sampling technique. Four hundred forty nine among the 527 students had brought lunch. The contents of lunch box were weighed and converted into nutritional values according to the food composition table and compared with recommended dietary allowances. The results compared and classified by sex, School and housewives' educational level were as follows: 1. The nutritional supply in the lunch box was 671 Cal of energy and 22.3 gm of protein for male students which were respectively 55.9% and 74.2% of the dietary recommendations. On the other side female student's lunch boxes were found to contain 495 Cal of energy and 21.3gm of protein which are respectively 61.8% and 80% of the dietary prescriptions. Excluding niacin, all vitamins and minerals were found to be short. 2. Calorie intake in the vocational high school was found to be higher than in the general high school but lower in protein intake especially significant difference (P<0.01) in animal protein. 3. From the nutritional point of view the educational backgrouud of the housewives was not found to have any influence in the way of preparing the lunch boxes. 4. Nutrients of lunch box were heavily inclined to grain rather than to side dishes.

There was an outbreak of food poisoning on the 17 October, 1970 among the primary school children who came from a rural area, Yeongi-gun, Choongcheongnam-do to Seoul City on an educational trip. Of the 199 children participating in the trip, 149 cases of food poisoning developed a 74.9% attack rate. The acute onset of symptoms, of abdominal pain, diarrhea, vomiting and headache which occurred 1-5 hours after eating their lunch suggests that the outbreak was due to staphylococcal food poisoning. The common source of food was identified as the lunch packed in a chip-box which were eaten on October 17 during the trip. Most probable kind of food of the lunch as the cause was the favoured fish paste. The lunch were prepared at restaurant A in Seoul City. One of the personnel of the restaurant had a unhealed cut wound on the third finger tip of the left hand, from which it was considered that the food was contaminated with Staphylococcus during preparation. The chance of multiplication of Staphylococcus to produce enterotoxin in the food might be existed during flavouring the food with some degree of heat, and also during about 10 hours elapsed before serving the food after preparation.

The purpose of this study was to investigate the quality attributes and importance that affects their satisfaction with respect to lunchboxes amongst children from low-income families in Korea. In case of $1-3^{rd}$-grade elementary school, 57.1% received lunch box through the community child center, while 45.2%, 68.5% and 80.7% of $4-6^{th}$-elementary school, middle school, and high school students received the lunch box from home, respectively. Typically, in 40.2% of all grades, the time to eat the meal was within 1~2 hours of delivery, and 34.0% consumed the lunch within 2~6 hours of delivery. With respect to intake of the contents of lunchboxes, 72.0% of the participants answered that they ate 80% of the lunchboxes delivered and 24.9% only ate 50% of the content of lunchboxes. The largest leftover were vegetables (26.9%), and the reason for leaving food was 'do not like to eat (36.1%)' followed by 'no taste (32.6%)'. Regarding improvements in delivery lunchboxes, elementary school students selected 'taste', while middle school and high school students selected 'variety of menu'. The 'nutrition (3.69 point)' of the lunchboxes was the highest satisfaction and the 'variety of menu (3.34 point)' was the lowest. In all grades, 'nutrition' and 'hygiene' were considered to be important as quality attributes of the delivery lunchboxes, and satisfaction was also high. On the other hand, in the $1-3^{rd}$-grade elementary school, 'variety of menu' and 'amount of side dish' were important but satisfaction was low. The $4-6^{th}$-grade elementary school, middle school and high school students stated that 'taste' and 'variety of menu' were important, but satisfaction was low.

The 1-serving lunchbox app is designed and developed for enabling consumers to order their lunch box by choosing their own lunch side dishes. In modern society, one-person households are growing in larger areas. It is too burdensome to handle alone because it is cumbersome to cook alone and you should order from two people in a restaurant shop. To resolve such inconveniences, it is an app to choose various detailed menus and order personalized lunches. In the process of selecting a detailed menu, information provided by big data is used. You can use the existing order through the bookmark function, or you can use the recommended lunch menu using big data.
