  • In order to reproduce Sanghwabyung that people in the past made and ate at Yuduil (June 6th by lunar calendar) among our traditional rice cakes, this study manufactured Sanghwabyung with black wheat flour by adding the wheat bran and Nuruk powder as leavening source, according to the old cook book "Gyuhapchongseo" and analyzed the quality characteristics. As a result of total phenol and flavonoid contents, DPPH radical scavenging activity of black wheat contents showed the gradual increase significantly (p < 0.001). The number of lactic acid bacteria was $6.72{\times}10^7$ CFU/mL just after preparation, and the number of yeast was $5.59{\times}10^7 $ CFU/mL. The number of lactic acid bacteria and yeast increased after 24 h to $8.48{\times}10^7$ CFU/mL and $5.40{\times}10^7$ CFU/mL. Hard-ness was the lowest in WF30%, compared with the C and the highest in BF100% and WF100%. The more the added portion increased in WF30% and BF30%, the more the hardness increased significantly (p < 0.001). The cohesiveness was the highest in WF30%, compared with C and BF30%, the lowest. It was shown significantly different between the C and WF and BF sample groups (p < 0.01). Springiness was the highest in WF10% and WF50%, compared with that in C and BF100%, which were the lowest. Springiness decreased significantly (p < 0.001) ad-ded portion increased between WF30% and BF30%. Gumminess was the highest in BF100% and WF100%, whereas that of WF20% was the lowest (p < 0.001). Chew-iness was the highest in BF100% and WF100% (p < 0.001).

  • Herbs have unique tastes and flavors, and they have been used in western foods. This study used herbs to make cookies. The purpose of this study was to investigate the sensory characteristics of cookies with rosemary(1, 2, 3, 4%) and mints(1, 2, 3, 4%) after foretasting herbs. The sample of this study was 880 college students which consisted of 436 males and 444 females. The results of this study were as follows. This study was conducted to find a high quality product through a sensory test with rosemary and mints. First, in terms of foretasting experience, the respondents had tasted 12 herbs. 65.2% of them preferred parsley, followed by mint(45.2%), bay leaf(44.0%), rosemary(28.3%), basil(21.8 %), etc. Second, in terms of the most important items while making herb added to bread and cookies, taste was high with 45.8%, flavor 27.3%, price 10.1%, nutrition 8.5%, etc. There were significant differences between genders and among majors(p<0.001). Third, it was found that appearance was high with 2% added group(M=6.00) in terms of sensory preference. The flavors, tastes, texture, overall acceptability were high with 1% added group in terms of sensory preference of cookies with rosemary. The respondents showed low preference for cookies with mints. While the 1% added mint group showed the highest preference for appearances and texture, the control group showed the highest preference for flavors, tastes and overall acceptability. There was a significant difference in appearances and tastes on all samples except colors and taste of rosemary added cookies $(p<0.05{\sim}p<0.001)$. Fourth, males preferred 2% rosemary added one in appearances and tastes in a sensory test. They preferred the 1% rosemary added group in terms of flavors, texture, and overall acceptability. Females preferred appearances of cookies with 2% rosemary and also preferred flavors, tastes, texture and, overall acceptability with 1% rosemary. Both of them less preferred 4% mint added one. Overall, this study found that respondents preferred 1% rosemary herb cookies. There should be further researches with less than 1% mint to make herb cookies.

  • 본 연구는 한국보건사회연구원의 "2009년도 전국 결혼 및 출산 동향 조사" 패널자료를 활용하여 20~44세에 이르는 2,678명의 미혼 남녀(남 1,425명, 여 1,253명)가 생각하는 이상적인 일 가정 양립 방안, 성역할 태도 및 저출산 원인에 대한 견해 등을 성별 및 교육정도에 따라 알아보고 이들 사이의 관계를 탐색적으로 분석해 보았다. 이를 통해 향후 저출산 문제 해결을 위해 미혼 남녀들의 일 가정 양립을 어떻게 지원할 것이며, 이 과정에서 미혼 남녀의 성역할 태도가 어떻게 변화되어야 할 것인가를 유추해 보고자 했다. 연구결과를 정리하면, 첫째, 이상적인 일 가정 양립 방안은 미혼자의 성별에 따라 차이가 없었으나 교육정도에 따라서는 통계적으로 유의한 차이가 드러났다. 둘째, 이상적인 일 가정 양립방안과 부부 성역할 태도 및 성별 간 관계에 있어서는 여성에 비해 남성이 '남성은 직장, 여성은 가사'를 더 찬성했으며, 전일제일 보다 시간제 일을 선호하는 미혼자들이 '남성은 직장, 여성은 가사' 방안에 대한 찬성이 높았다. '남편의 자녀 돌봄 능력'에 대해서는 여성이 남성보다 그리고 2자녀를 두고 전일제로 일하겠다는 미혼자가 1자녀를 두고 전일제로 일하겠다는 미혼자에 비해 높은 평가를 보였다. 셋째, 두 자녀 이상을 두고 전일제로 일하고자 하는 미혼 남녀가 저출산 문제를 가장 심각하게 받아들이고 있었다. 넷째, 저출산 이유로 가장 높은 동의를 보인 것은 '양육비와 교육비용'이었으며 다음으로 '주택마련의 어려움'과 '취업여성의 증가'였다. "취업여성의 증가"를 저출산의 원인으로 여기는 정도는 남성보다 여성이 높게 나타났으며, 무자녀로 전일제 일하는 것을 원하는 미혼자들에게서 이러한 성향이 두드러지게 나타났다. 이러한 연구결과를 통해 일 가정 양립방안과 성역할 태도에 대한 기본적인 이해를 높일 뿐만 아니라 저출산 문제에 대한 정책적 개입방향을 제시하고자 하였다.

  • Objective The purpose of this study was to investigate health and life style of pediatric outpatients who visited the oriental hospital. Methods The study was composed of 363 students from elementary school, middle school and high school who visited the pediatrics department in $\bigcirc\;\bigcirc$ university oriental medicine hospital between 2005 and 2006. Results 1. The group wasconsisted with 56% of male and 44% of female student and for the age distribution, 7.4% were elementary school students, 55.6% were middle school students, and 36.9% were high school students. 2. Usually the eldest child tends to visit hosipital more than the younger ones. 3. More than a half of those students' parent had University education or beyond that. 4. There were more students who had below the level of the height-weight curve than in the higher level. 5. The average study hours of the students were 3.67 hours. An average sleep hours was 6.18 hours. An average exercise hour was 1.16 hours and an average time for watching TV was 1.71 hours. 6. Many students had hard time to concentrate on the studying for a long time. 7. For the question about the reason why they got the poor grade, they answered because of the lower concentration, and they didn't put much effort on the studying. The most they concern about was their grade. 8. Most of the students who visited the clinic said they did not feel refreshed when they woke up in the morning, and, many of them said that they don't feel okay. 9. More than an half of the students wear glasses. 10. More than an half of the students answered that they often catch a cold when the weather changes a lot. 11. A lot of them had some digestive problems. 12. As they getting older, they said they often feel back pain and shoulder pain. 13. Many students felt irritated and got mad easily. Many of them felt bored about their study and stressed out because of their tests and the university entrance exams. 14. Most of the female students answered that they have irregular period or cramps. 15. 21% of them usually skip breakfast. 16. Many students enjoyed snacks. Most of them enjoyed snacks after school. As they go into higher grade, they would like to eat at night especially cookies, bread and fruits. Conclusions Further studies with larger sample size of students will be neededfor accurate results, and it would be better if we can compare the conditions of the students before treatments and after those.

  • Wheat was brought to solve food scarcity with aid from the United States caused by the Korean War. The Korean government launched a campaign to encourage mixed rice and wheat meals due to shortage of rice production in the 1960s, Wheat consumption began in earnest. However, it is difficult to rebuild the domestic wheat production base devastated by the Korean War with the technology at the time. Thus, wheat was mainly consumed from imported in the past. Since then, as wheat consumption has increased due to westernization and diversification of dietary life, wheat became the second staple grain in Korea. In this situation, the government enacted the Wheat Industry Promotion Act to create a basis for sustainable production and consumption of wheat in Korea. This study sought to improve the self-sufficiency of domestic wheat by examining the possibility of using "Ariheuk", a variety of new Korean wheat, as a rice supplement in the same context as the govemment's policy. Wheat has been used as a raw material for the processed food, such as noodles and bread. However, we approached it by using whole wheat as a nutritional grain. Participants were recruited from the agri-food consumer panel conducted by Rural Development Administration. We set a final sample of 525 consumer panels based on the age of census household heads. The experiment was conducted in such a way that participants cooked and ate 100% rice meal and rice containing 20% whole wheat meal. Participants completed the sensory evaluation questionnaire with online. For this experiment, all participants were given same whole wheat product. The sensory evaluation questionnaire consisted of color, glossiness, stickiness, aroma, chewing, sweetness, nuttiness, chewiness, softness, bursting, flavor, texture and swallowability. The sensory evaluation results were analyzed by giving -3 points to +3 points. The former points were given to the response that 100% rice meal is very superior to the response that rice containing 20% whole wheat meal. The latter points were given vice versa. Zero point was given to the response that they are similar each other. As a result, rice with 20% whole wheat meal was better than 100% rice meal in terms of color, aroma, chewiness, bursting and flavor. In case of sweetness and glossiness, there didn't exist significantly different. On the other hands, 100% rice meal was better in terms of softness and swallowability. As a result of ANOVA by age groups, from 30s or younger to 60s or more, there was significant difference among the groups in terms of color, chewiness and bursting. As a result of post-hoc analysis with Duncan's multiple range test (p < 0.05), 50s were evaluated to be significantly superior in color, chewiness and bursting compared to other age groups. In conclusion, it is appropriate to use whole wheat as a supplement to rice in order to improve the self-sufficiency of domestic wheat. As a strategy to promote domestic wheat consumption, in case of Ariheuk, it is necessary to provide an experience through whole wheat tasting and to establish a marketing strategy segmented by age groups.

  • This study concerns the nutritional status of food in a lunch-box and the school lunch program provided for Dong Duck Elementary School Pupils in Daegu. Two hundred andsix pupils were randomly selected as a sample. The nutrients contained in a lunch-box and school lunch menu were analyzed according to the Food Composition Table. Nutrients and cost of the Dong Duck Elementary School Lunch were compared to the average nutrient contents of food in a lunch-box of o pupil. In addition, comparisons between the Recommended Daily Allowances of nutrients for Korean children aged from 9 to 11 (4th, 5th, and 6th grade) and that of the contained nutrients in the average lunch-box were conducted. The average nutrients contained in the lunch-box compared with the Recommended Daily Allowances are: Calorie 77.41% (542.60ca1), Protein 73.60% (16.93gr), Fat 33.95% (3.95gr), Calcium 27.85% (111.39mg), Ferret 80.30% (2.65mg), Vitamin A 10.09% (100.93 I.U.), Vitamin Bl 70.27% (0.27mg), Vitamin B2 88.37% (0.38mg), Vitamin C 15.40% (3.45mg). All of the nutrients in the lunch-box fall far below the Recommended Daily Allowances for the 9-11 age group. The average nutrients of staple food in the lunch-box compared with the side-dishes were found to contain Calorie 90.80%, Protein 50.32%, Fat 58.27%, Calcium 37.07 %, Ferret 53.96%, Vitamin A 0.0028%, Vitamin B1 78.11%, Vitamin B2 21.09%. The nutrients of food contained in the Dong Duck Elementary School Lunch Program compared with the Recommended Daily Allowances were: 1. The Protein, Fat, Ferret, Vitamin B1 and Vitamin B2 content was generally satisfactory. 2. Calcuim, Vitamin A and Vitamin C were lower than the Recommended Daily Allowances. 3. The Calorie content was generally lower for the 9-11 age group. The per pupil cost of the lunch-box was 41.87 won which includes the cost of staple food 16.92 won and side-dishes 24.95 won, whereas the school lune Provided by Dong Duck Elementary School Costs 35 won per pupil. Questionnaires were sent to four hundred parents (through their children) to find out their attitude toward the school lunch program. 390(97.50%) of them were returned and 7 of them dia not answer at all. Therefore, these were eliminated from the samlpe. Among 185 parents whose children were eating the school lunch; 172 parents (92.97% ) would pay 40 won for the proposed new school lunch program whereas only 13 parents (7.03%) did not want it. Among 198 parents whose children were not having the school lunch, 58 parents (29.29%) would agree to have the lunch for their children at the cost of 35 won with the proposed new school lunch program equivalent to 40 won. 126 parents (63.63%) could not agree to have their children being the school lunch because of their financial difficulty (74 parents 58.72%). The rest of parents (52 parents 41.28%) raised other reasons which were minor problems. Among the tatal of 383 parents, 309 parents (80.68%) would agree to gave school lunch for their children if the cost of the proposed new school lunch program would be 35 won to 40 won and if minor problems concerning the school lunch program are solved. Sixty parents (15.66% ) raised questions about the school lunch program concerning sanitary problems, taste of bread, and the quantity of lunch. Among 383 parents, 358 parents answered and 25 parents did not. When school officer asked if the parents would help during the school lunch hour, 101 parents indicated they could not help at all, but 177 parents, replied they could help. Among 177 parents, 40 parents of them could share their time from one or two hours everyday except Saturday and 107 parents could serve 1 to 3 days per week. Through this study, it is evident that further investigation should be done of the school lunch program which can be provided 35 won with the proposed new school lunch program. The parents participation in the school lunch program would be improved the understanding between school and parents as well as insure better nutrition and sanitation for the children.
