The purpose of this study was to investigate the effects of nine times repetitive steaming and drying process Sunsik diets on antioxidant activity in obese mice fed high fat diets to prevent oxidative stress, using drying materials comprising 23 kinds of cereals (61.5%), beans (30.0%), sweet potato and potato (3.0%), fruits (2.0%), vegetables (3.0%), and stevioside, a natural sweetener (0.5%). We produced three samples: the experimental group was classified into the normal diet group (control), the high fat diet group (HF), and the high fat diet group + the Sunsik group (3HFS, 7HFS, 9HFS) fed to the mice for eight weeks. As a result, the serum, liver lipid peroxide, and nitric oxide levels were significantly higher in the HF group than in the C group at p<0.05 level, and the NO level was lower in the Sunsik supplemented groups. The antioxidant enzyme catalase activity significantly decreased in the HF group at the p<0.05 level compared to the C group. The total antioxidant activity of the C group was significantly higher in serum, liver, and kidney tissues than the HF group (p<0.05). The anthocyanin level in liver and spleen tissue was significantly higher in the group fed Sunsik than in the HF group.

This study examines the high school girls in Inchon area dividing them into three groups according to their weight, the low-weight group, the normal weight group and the overweight group to find out their food habit and food preference. The result reveals that more students from the low-weight group have breakfast regularly than those from the other two groups, and more students from the low-weight and normal weight groups always have lunch. However, none of the students from those three groups skip their suppers. This study also shows that there are more students from the overweight group having snacks, and more students from the low-weight have the unbalanced diet problem than those from the other two groups. Next, this study examines their attitude toward breakfast. It seems that all the students from three different groups similarly regard breakfast as a very important meal. Additionally in deciding what to eat, the taste of food is considered as the most important factor for them all. In their preference of food taste, there seems to be a slight difference. The students from the low-weight and normal weight groups prefer hot food to sweet food, but those from the overweight group prefer sweet food to hot food. Also in food preference the difference among the groups is that the students from the low-weight and normal groups prefer favorite food and snacks. While those from the overweight groups prefer cereals and noodles.

The effects of the vegetable diet on the levels of the serum lipids, particularly the level of the serum total cholesterol which is most concerned with coronary heart disease (CHD) were investigated in 30 male SDA (Seventh Day Adventists) group and 30 male omnivorous group (control group). SDA participated in this study intaked relatively few animal origin foods whereas they intaked plant origin foods largely; they seldom or sometimes intaked meats, fishes, butter, margarine, beverages and coffee, but often unrefined cereals, legumes, vegetables and fruits. In the both systolic pressure and diastolic pressure, there was no difference between two groups. The levels of the serum total cholesterol, triglyceride and phospholipid were lower in SDA group than in the omnivorous group. Among them the difference was statistically significant in the level of the serum total cholesterol. HDL-cholesterol was more or less higher in SDA group than in the omnivorous group, but the difference was no significant. The result that SDA group had lower level of the serum total cholesterol than the omnivorous group suggested that that they might be less prone to CHD than the omnivorous group. Though this possibility, however, was derived from the fact of the lower level of serum total cholesterol of SDA group, it might by partly responsible for their habit that they never smoke and drink alcohols and coffee.

Traditionally, genetic variability is generated by an extensive crossing program, which is complemented by strict selection to identify useful new recombinants. Plant biotechnology offers many opportunities for breeders to solve certain breeding problems at the molecular level. The tissue culture methodology and the genetic modification of economically important monocotyledons have undergone a revolution in the last decade. As the production of transgenic plants is a complex procedure, including the uptake of DNA molecules into the cells, the integration of foreign nucleotide sequences into the host genomic DNA and the expression of new genes in a controlled way, and as there are still many unsolved questions, further development is necessary. The methodology opens up the possibility of introducing novel genes that may induce resistance to diseases and abiotic stresses, allow the modification of dough quality and the dietetic quality of proteins, and increase the levels of micronutrients such as iron, zinc, and vitamins. In the present review, the authors would like to summarise the most important advances in wheat transformation.

This study investigates the influence of self-efficacy in purchasing clothes in the consumer satisfaction formation process. A survey was conducted on 300 adults living in the Seoul and Gyeonggi area and 231 completed questionnaires were used for analysis. The survey questionnaires measured the respondent's self-efficacy in purchasing clothes, expectation, perceived performance, expectation confirmation, and satisfaction level. The data were analyzed by moderated regression analysis. The results are as follows. First, for apparel products, perceived performance, and expectation confirmation have a direct effect on consumer satisfaction, while expectation has no direct effect on consumer satisfaction. This finding agrees with the results reported in a previous study on consumer goods with low ambiguity in assessing products and services including sneakers, underwear, cereals, and financial services. Second, the lower the self-efficacy in purchasing clothes, then the increased effect of the expectation confirmation that influences consumer satisfaction. However, the self-efficacy in purchasing clothes did not show any moderating effect on the perceived performance affecting the consumer satisfaction. The self-efficacy in purchasing clothes seems to have a moderating effect on the consumer satisfaction formation process by affecting the ambiguity in pre-purchase product assessment and not in post-purchase product evaluation.

This study was conducted to investigate the weaning practice of 198 infants in Taejon city in October, 1998. Information on infant feeding and weaning practices were obtained by interviewing mothers in gynecologist and pediatric clinics located in Taejon. The results obtained were as follows : In the survey 37.4% of the infants were breast-feeding, while 31.3% of them were bottle-feeding and 29.3% of them were mixed-feeding. The reason for bottled-feeding was due either to the lack of breast-milk secretion or motner’s job. The educational level of the mother and maternal job affected the feeding methods before weaning. Lower rates of breast-feeding were found among mothers witn a lover level of education. The breast-feeding rate was lower in full-time and part-time job worker groups than in housewife. There was no significant difference in the feeding methods according to family income. Among the subjects, 71.5% of infants began to be weaned within 7 months. The onset of weaning was delayed in the full-time worker group. There was no significant difference in the onset time of weaning according to feeding method, the educational level of the mother, and family income. 60.6% of infants received fruit juice and 29.6% of them received cereals for first-given-supplementary food. ‘For baby’s nutritional status’ was the most common motivation for the onset of weaning. Commercially prepared foods were used more than home-made food for supplementary food.

The purpose of this study was to investigate the dietary intakes of preschool children in rural areas and to develop programs of nutrition education, offering the mothers an appropriate advice for the improvement of the dietary practices corresponding to the modernization of the agriculture. The daily food intakes of 118 preschool children, randomly selected from the farm household, were studied by means of three-day records during summer season of 1972. The results showed that the dietary intakes of food groups such as meats and fishes, beans and the products, milks and small fishes, fruits, fats and oils were below 50 per cent of the recommended level-especially in that of milk. Therefore, the diet was generally below the recommended dietary allowances for protein with good quality, fat, calcium, vitamin A, thiamine, reboflavin and ascorbic acid. The dietary data revealed that most of preschool children in rural areas consumed rice and barley, almost every day. Other foods eaten less frequently were soybean paste, gimchi, potatoes, flour, and summer squash. The use of cereals should be curtailed some what and the use of milks, fishes, poultry, meats and protein extenders should be increased.
