This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.

This study was conducted to compare the eating habits of disabled and non-disabled children in Seoul and Gangneung. Korea. Questionnaires about eating habits were answered by the children's parents and their teachers. The subjects of this study consisted of 146 disabled children (108 boys and 38 girls) from two special education schools and 241 non-disabled children (control group,120 boys and 121 girls) from two elementary schools in Seoul and Gangneung, respectively. The percentage of the children who required more than 30 minutes to eat was 11.3% in the disabled group and 2.5% in the non-disabled group. In the disabled group,44.0% ate excessive amounts of food or could not control their intake. The percentage of the children whose frequency of eating breakfast was less than 1 to 2 times per week was 21.0% in the disabled group and 9.7% in the non-disabled group. Also, 7.6% of the disabled group and 13.9% of the non-disabled group had snacks more than three times per day. The percentage of children who were able to eat by themselves was lower in the disabled group (47.9%) than in the non-disabled group (87.8%). Of the remainder of the disabled group,28.6% spilled food, and 14.3% needed the aid of others when picking up side dishes. The percentage of parents who worried about their children's eating an unbalanced diet was 48.5% in the disabled group and 41.8% in the non-disabled group. In addition, there were problems with eating behaviors in 22.7% in the disabled group, and with under-eating (15.9%) and with excessive intake of instant foods (16.8%) in the non-disabled group. These results suggest that the eating habits and eating behaviors of disabled children are different from those of non-disabled children. Thus, nutritional educational programs and educational materials for disabled children and their parents should be developed.

The purpose of this study is to analyze working mothers' demand for child care and housekeeping home services, and to investigate the present supply condition of home services in Korea. Data collection was implemented to examine the service demand of working mothers(n=700) in four areas. The data were analyzed with SPSS. The results were as follows: 1) For home-based child-care dispatch services social enterprises are superior to other private service suppliers in terms of the treatment of service workers, wages, and quality control. As for child care service contents, the provision of meals, and casual safeguards were mostly expected. The most important qualification for care providers was found to be in faithfulness, and the certification related with child care was required. An affordable wage range was perceived as ￦3,000~5,000 per hour, and part time services. For the time range, services which commenced before 9 am and terminated after between 5~6 pm were preferred. 2) For housekeeping dispatch services, standard services, including basic cleaning, preparation of meals and side dishes, special cleaning, and washing, were in demand. The required qualifications of housekeeping service providers were similar to those of child care service providers. Possessing certification was not considered as an important quality; however, personality and career type were important factors. An acceptable wage range was ￦3,000~5,000 per hour and part-time services were preferred. In terms of the service time range, services which commenced between 8~9 am and terminated between 5~7 pm were preferred.

This study is to research the use and the demand of the elderly generation that pursue economic ability and active lifestyle. The composition of the meals were "homemade meals" 65.3%, "homemade & convenience meals" 26.7% overall. For the "never miss a meal" category, 70-74 years old was 48.3%, over 80 years old was 60.0%. The elderly under 70 years old showed a high frequency in the use of alternative meals (p < 0.05) and the elderly with higher education used the alternative meals more frequently (p < 0.01). The rice-cakes, bread, tuna cans, Korean side-dishes, beverages, meat, cup-noodles and seafood as alternative meals are in the order of most frequency. Also, 96.0%, 59.0% and 46.5% of the elderly had experience in using "Ready to eat (RTE)", "Ready to heat (RTH)" and "Ready to cook (RTC)". The oldest group surveyed, the elderly at the age of 80 years old and above showed lower preference for "completely cooked state" but showed highest results in the "half-cooked state". This shows the difference between people's perception and the behavior that showed high frequency of 96.0% in the experience with "RTE". This can be inferred that the elderly needs the development of convenience food that is moderately packaged according to the newer lifestyle where the elderly live independent from their children. Moreover, there is a higher demand in the healthy convenience food, which means that there is a need for development in the quality of the convenience food that will allow more faith in convenience food by the elderly.

In this study, the reproducibility of blood alcohol concentration (BAC) - time profile for the same individuals were investigated. Five Korean males were made to drink 55.5 g of ethyl alcohol (neglecting body weight) in the form of undiluted Soju (22% v/v), Korean popular liquor, within 30 min and each drinking sessions were performed for five times. Two kind of side dishes, a sliced raw fish and a sweet and sour pork, were served alternately along with alcohol. The peak BAC reaching time, the maximum BAC and the reduction rate of BAC of an individual varied greatly even though the dose and drinking time interval were not changed. Also, the food taken along with alcohol varies the shape of BAC - time profile. From the repetitive drinking sessions we can know that the BAC - time profile of an individual is not a reproducible one even though the dose, kind of liquer, drinking time and food were maintained constantly. It means that any assumption of blood alcohol concentration of an individual at a previous time stage based on the alcohol dose can not be justified because of large fluctuation of BAC-time profile of an individual.

This research was carried to investigate the food preference of students, from elementary school, middle school, high school, university and industrial workers on Jinju, Sacheon and Jinyang by age and sex. The results were obtained as follows. In case of rice as the stationary food, plain white boiled rice showed the highest preference among all the groups. Most of groups liked most of one-dish meals such as kimbab, fried rice with kimchi, dumplings and bibimbab, especially the elementary school students and middle school students. On the other hand, high percentage of industrial workers disliked the western food such as pizza, hamburger and sphagetti. Most of subjects liked jajangmun, nangmun and bibimgooksu as noodles. As the side dishes generally they prefer the soup to stew. Male prefer the soup with beef and female prefer soup with vegetables. Stew with kimchi and stew with soybean paste showed high preference among most of groups. Most of broil food showed high preference, and students prefer meat to fish as broil cooking materials especially younger students. As a general they liked soybean sprout, spinach and wild sesame leaf as namul cooking method and they liked korean cabbage kimchi, chonggak kimchi, kackdoogi and dongchimi as kimchi. As a dessert subjects liked most of fruits and they liked yoghurt, fruit juice, milk, sikhae and soda as drinks generally. On the other hand snacks such as cooky, candy, cake, corn, rice cake, sweet potato have the lowest percentage preferance as a dessert, but students from elementary schools showed the highest preferance to sweet such as cooky, cake and candy than any other group. These food preferance results showed some nutritional problems especially young age students. They should eat more green-yellow vegetables, liver food and dried small sardine and they should reduce snacks such as candy and cooky and soda drinks. Therefore it is necessary to conduct nutrition education by parents, teachers and dietician together to improve their food habits and their health.
