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.

To study the importance of family meals in adolescents, 251 middle school students were surveyed through a questionnaire on their family meal patterns, dietary behaviors, food intake, and life satisfaction. The family meals were defined as "meals with all family members living together" by 62.2% of the students. For the frequency of family meals, 42.2% of the students replied having family meals "More than once a day". A common reason for the difficulty in having a family meal was a "lack of time" (73.3% of the students). Students tended to respond that they would be most fond in having meals with entire family members with traditional Korean food. Having more frequent family meals was found to benefit both individual and familial dietary behavior. In terms of food intake according to the frequency of family meals, the group having frequent family meals consumed significantly more rice, tofu, legumes, meats, fishes, eggs, green vegetables, seaweeds, fruits, milk, and milk products. This indicates that students can achieve a balanced diet through family meals. In terms of emotional status, the group having more frequent family meals showed a higher satisfaction with their daily life, health, nutritional status, and care from their relatives. In terms of personal mental status, the group having more frequent family meals was also found to be more effective at controlling undesirable emotions such as loneliness, indignation, and lethargy. As a result of this study, students in the group having more frequent family meals were found to have a positive dietary behavior, a balanced nutrition, a higher life satisfaction, and a more stable mental status. This result is useful as nutritional and educational information in schools to impress upon the public the importance of family meals for adolescents.

The present study was conducted to investigate the effects of different dietary proteins as fraction-enriched protein, defined by Cornell net carbohydrates and protein system (CNCPS), on in vivo ruminal fermentation pattern and blood metabolites in Holstein steers fed total mixed ration (TMR) containing 17.2% crude protein. Four ruminally cannulated Holstein steers in a $4{\times}4$ Latin square design consumed TMR only (control) and TMR with rapeseed meal (AB1), soybean meal (B2), and perilla meal (B3C). Each protein was substituted for 23.0% of crude protein in TMR. Rumen digesta were taken through ruminal cannula at 1 h interval during the feeding cycle in order to analyze ruminal pH, ammonia-N, and volatile fatty acids (VFA). Plasma metabolites in blood taken via the jugular vein after the rumen digesta sampling were analyzed. Feeding perilla meal significantly (p < 0.05) decreased mean ruminal pH compared with control and the other protein feeding groups. Compared with control, feeding protein significantly (p < 0.05) increased ruminal ammonia-N concentration except for AB1. Statistically (p > 0.05) similar total VFA appeared among control and the supplemented groups. However, control, AB1, and B2 showed higher (p < 0.05) acetate concentrations than B3C, and propionate was vice versa. CNCPS fractionated protein significantly (p < 0.05) affected concentrations of albumin and total protein in blood; i.e. plasma albumin was lower for control and B2 groups than AB1 and B3C groups. Despite lack of significances (p > 0.05) in creatinine and blood urea nitrogen, AB1 and B2 groups were numerically higher than the others.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.

이 연구는 남성들의 은퇴가 활발히 일어나는 연령층 부부들의 식사 및 관련 행위를 분석하고 있다. 이 연구는 가사노동을 다루어 온 많은 연구들과 중첩되는 측면이 있으나, 식사준비, 식사행위, 설거지 등의 개별항목을 끼니별로 접근함으로써 일상적인 삶의 구체적인 모습에 한걸음 더 다가가고 있다. 한편, 대부분의 기존연구와는 달리 개인의 특성과 함께 부부나 배우자의 특성을 함께 고려하여 분석을 시도하고 있다. 한국통계청이 실시한 2004년도 생활시간조사자료 중 40대 후반부터 60대 후반 사이의 기혼여성들과 그 배우자들의 식생활행위를 분석해 본 결과, 부부의 식사행위, 식사준비 및 설거지 양상 등은 무엇보다도 부부의 취업형태에 따라 큰 차이를 보인다. 부부의 취업형태를 중심으로 볼 때, 부부가 함께 식사하는 비율이 가장 낮은 것은 부인만 취업한 상태이다. 은퇴연령층에서 부인만 취업하고 있다는 것은 이들이 식당 등과 같은 서비스업에 종사할 가능성이 높으며, 이로 인해 부부가 함께 식사할 수 있는 기회가 적음을 의미한다. 한편, 부인만 식사준비 하는 비율은 부인만 취업한 경우가 다른 경우보다 낮게 나타난다. 그럼에도 불구하고 부인만 취업한 경우에도 부인만 식사를 준비하는 사례가 절반 정도에 이른다. 부인만 설거지를 하는 비율 또한 식사준비를 하는 비율의 패턴과 유사하다. 이 비율 또한 부인만 취업한 경우에 가장 낮지만, 상당 수준에 이른다. 이를 통해 볼 때 식사준비와 설거지를 하는 해당 연령층 부인들의 비율은 취업상태에 따라 분명한 차이를 보이지만 대체로 이들 행위들은 여성들의 몫으로 남겨져 있다. 이는 다시 가족 내 식사준비와 설거지 등과 같은 일상적인 삶의 행위가 가족내 성역할을 반영하고 있음을 보여준다.

The objective of this study was to estimate changes on the flood and nutrient intake patterns of men over thirty years old in Jeon-Ju area. The first survey was conducted from December in 1991 to January in 1992, tile second one from January to February in 1994 and the third one from July to August in 1997. The nutrition survey using 24-hour recall method was executed to 303 subjects : 89, 82, 132 in 1991, 1994 and 1997, respectively. Results of the study are as follows : Kimchi, rice, garlic and onions were the most frequently eaten food items. Total daily intakes of foods were 85 : 15, 81 : 19 and 81 : 19 in 1991, 1994 and 1997, respectively. The average numbers of foods per person were 15.7, 20.1 and 21.9 daily in 1991, 1994 and 1997, respectively and tends to increase significantly(p<0.05). The minimum numbers of foods per person were 4, 7 and 9 and the maximum numbers of foods per person were 27, 35 and 39 in 1991, 1994 and 1997, respectively. KDDS(Korean\`s Dietary Diversity Score) is determined by how many among the five food groups (cereals, vegetables, meats, milks, oils groups)were consumed per day. Most subjects earned the KDDS "3" ; 61, 46 and 42% in 1991, 1994 and 1997, respectively. Average daily energy intakes wee 1,62㎉(72% of RDA), 2,063㎉(89% of RDA) and 1,818㎉ (79% of RDA) in 1991, 1994 and 1997, respectively. Energy intake rates of cereals : total energy intake were 65, 59, and 60% in 1991, 1994 and 1997, respectively, which were decreasing. Protein intakes were 58g(72% of RDA), 79g(107% of RDA) and 71g(97% of RDA), respectively and animal protein comprised 46, 53, and 59%, respectively ; which were increased. Fat intakes were 12g, 20g and 20g, respectively and animal protein comprised 38, 46, and 48% ; which were increased. Fat intakes were 12g, 20g and 20g, respectively, of which animal fat comprised 46, 53, and 59%, respectively ; which were increased, too. Malnourished (under 75% of RDA) rates were respectively 64, 34, and 47% in terms of energy ; 64, 31 and 33% in protein ; 67, 51, and 61% in calcium ; 53, 26, and 18% in iron ; 85, 74 and 84% in Vitamin A. Super-nourished(above 125% of RDA) rates were respectively 1, 13, and 3% in energy ; 1, 29, and 21% in protein ; 5, 18, and 7% in calcium ; 16, 31, and 7% in iron ; 16, 31, and 7% in Vitamin A, 42, 76, and 62% in Vitamin C. The percentages of calories from protein : fat : carbohydrate were 14 : 12 : 74, 15 : 16 : 69 and 16 : 17 : 67 in 1991, 1994 and 1997, respectively. KDDS(number of five food groups per day), Meal Balance(number of five food groups per meal), DVS(average numbers of foods per person), amount of foods correlated positively with all the nutrient intakes(p<0.05). KDDS was positively correlated with energy, protein, fat, calcium, thiamin, riboflavin and niacin(p<0.05)in(p<0.05)

This study was aimed at comparing the dietary patterns of university female students according to their residence type. As for subjects, one hundred and twenty students of Kongju national university were chosen as a total. They were devided into three groups ; those who live in family home, or university dormitory, or self-boarding house. In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day food records and questionnaire. The result was that mean daily intakes of calcium and iron were lower than RDAs in all groups. According to residence type, subjects of family home and self-boarding seemed to have more serious problem in the nutrients mentioned above considering the proportions of less than 2/3 of RDAs. Especially, iron status was poorer than any other nutrients in the aspects of this proportion and food source. Iron was taken largely from vegetable foods which were recognized as a source of low bioavailability of iron. The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 22, 29, 30 and 19. Thus, it proved that breakfast tended to be more negligent than any other meals, and that snack was an important means to give nutrients for subjects. This meal pattern might be one of the factor for the decrease of the dietary quality. Processed foods were founded to be an important source for providing nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients intake were 30.6, 29.5 and 46.2. However, other nutrient intakes from processed foods such as vitamin and mineral were small. And processed foods which give nutrients were mainly cereal products like ra myon, bread, and milk and milk products. Consequently, processed foods seemed to be selected as a combinient substitute food which supply calorie to fill their hunger. According to the living type, dormitory students had them more frequently than any other groups. Food habit score was within the category of poor or fair. Particularly, the score of self-boarding students was the lowest of groups(p<0.05). The major dietary problems were small or overating, missing meal and irregular eating. The degree of these problems was a little different among groups(P<0.01). Nineteen kinds of food were consumed per day, and family home and self-boarding students had foods less variously than dormitory students(P<0.05). Proportions of skipping breakfast, lunch and dinner were 20.8, 12.5 and 8.3%. Accordingly, breakfast was missed more often than any other meals. And self-boarding students missed breakfast more often than any other groups. As a conclusion, subjects should take more calcium and iron, and eat diverse foods to improve their nutritional status. And it is also necessary that breakfast should be regarded more importantly, and that processed foods should be taken considering nutritional balance. In view of residence type, subjects of family home or self-boarding had more dietary problems than dormitory subjects. Thus, these results suggest that university female students might have low ability of meal management, and dietary patterns were different by their residence type. Therefore, nutrition education for them should be carried out with respect to dewelling environment.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 2002. The subjects included 301 males (48.7%) and 317 females (51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index (BMI) was 3.7, 88.0 and 8.3 far the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time (65.1%) of the cases. Self-reported eating habit problems were eating irregular meal (52.4%), overeating (21%), prejudiced meal (12.4%) and skipping meal (7.4%). The type of favorite snack was biscuit (31.9%) and cup Ramyon (31.9%). The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.

The purpose of this study was to compare dietary patterns, dietary behaviors and life styles before and after breast cancer surgery in Korea. The subjects were 220 females who underwent surgery for stage I-III breast cancer at general hospitals. Food intake, eating habits, snacks, eating-out, use of nutritional supplements and healthy foods, and drinking and smoking habits were studied using a questionnaire. SAS program was used for statistical analysis of the data. The results are as follows : 1) Most subjects were housewives aged more than 40 years. 2) After breast cancer surgery, intakes of fruits and vegetables were increased and those of meat, salty and spicy foods were decreased. 3) There was a significant difference in takes of caffeine beverages, snacks, fast foods and instant foods before and after breast cancer surgery. 4) There was a significant difference in meal regularity and skipping breakfast before and after breast cancer surgery. 5) The frequency of eating-out was decreased and low-fat foods, such as Japanese foods, were preferred after breast cancer surgery. 6) Nutritional supplements and natural healthy foods were used more after breast cancer surgery. 7) Most subjects were non-smokers and drank little alcohol and the rate of regular drinking significantly decreased after breast cancer surgery. Therefore, there was a significant difference in dietary patterns and behaviors resulting form breast cancer. Further more, dietary factors may be a contributing factor in the incidence at breast cancer in Korea.
