This study was carried out to provide the improvable way of foodservice management to dietitian in the elementary schools. For this purpose the serving pattern of food, menu planing, nutrition education, leftover management and difficulties in foodservice were investigated. The survey was conducted through questionnaires, which were collected from 249 dietitions randomly selected in Taejon and Chung Nam. Data were analyzed by SAS program. The main results of this study are as follows. The children in Taejon took foods in the class room(65.7%) and those in Chung Nam in the dinning hall(89.9%)(p<0.01). In menu planning the balance of nutrition(42.6%) was mainly considered and then food preference(19.7%), variety of menus(16.1%), food cost(16.1%), composition of food color, taste and texture(3.2%), skills of food making(1.6%) and the number of students(0.8%). They referred cooking magazines(47.7%), the previous menu(42.2%), children's opinion(7.2%) for planing menu. The insufficiency of implements and devices for food(24.1%) and lack of season's food(20.4%) were indicated as difficulties in their job. 34.5% of dietitians used a standard menu, 79.5% investigated food preference of children, 74.3% evaluated taste of foods before serving, and 80.7% regularly checked leftover. The major reason for leftover was careless of the teacher in charge in Taejon and bad taste of foods nutrition in Chung Nam(p<0.001). 98.5% of them answered that they had the responsibility for nutrition education in elementary school. They had a hard time in relationship with the staffs in school(40.6%) and employees for food(39.8%), and lack of market information(38.2%). To efficiency of dietitian's work can be enhanced by reflecting the results of children's food preference and leftover, by using standard cooking method and proper cooking utensil, and by performing nutrition education for children by themselves.

To investigate the children's food habit, one thousand of children from eleven elementary school food service were randomly selected in Taejon. The survey was conducted by questionnaires and data were analyzed by SAS program. The results are summarized as follows. 1. The average height and weight for the 3th grader are 132.0cm and 29.4kg for boys. 131.2cm and 27.9kg for girls. In the case of the 6th grader the average height and weight are 147.1cm, 41.1kg for male, 148.6cm, 41.0kg for female, repectively. Those values are less than national averages. 2. The third grader eats breakfast more regularly than the sixth grader(p<0.001) and 51.5% of the children answer that they take foods for their health. The third grader has better eating habits than the six grader. This survey shows that the sixth grader eat more cereal, milk and vegetable and the third grader has less fruits than the sixth grader. 49.3% of the total children likes eating food at home, 36.6% eating outsid and 14.1% school meal service. 25.8% of the children reply that they do not eat now foods during school meal service. 82.5% of the total children are willing to eat foods served from school meal service if a teacher explains about the information of foods.

8.Food Preference of Elementary School Children Under meal service in Taejon.
Korean Journal of Community Nutrition 1998;3(3):440-453
This study was done to provide basic information for nutrition education and meal planning by analyzing children's food preference. For this purpose, 938 children from eleven elementary schools under meal service were randomly selected in Taejon. The survey was conducted by questionnaires, and data were analyzed by SAS program. Children prefered ssalbap to japkogbap and liked kimbap the best among one dish foods. But their most favorite foods were chajangmyun in noodles, miyeokkuk in soups, and chamchichigae in pot stew. Sixth graders like kimchichigae more than third graders. In the case of chims, children like duejigalbichim, sogalbichim, and dalgyalchim. In the jorim, they prefered duejigogi jangjorim, mechurial jangjorim to any other jorims. The preference of bockum, namul, jangachi, and jotgal is generally low. Children's preference is high in fruit, drink, fried food, one dish food and is low in jangachi, namul, bockum. These results suggest that the preference of foods should be fully taken into consideration in school meal service so that they can eat foods with pleasure. Foods, which are low in preference due to the cooking method, should be prepared with new cooking methods developed specifically for children. 'Even though the preference of food is low to the children, the nutritious foods should be utilized in the school menu. Then, the imporatance of food intake must be taught to them through nutrition education.

OBJECTIVETo study the function of the chalcone synthese gene introns in Scutellaria baicalensis, and clarify preliminarily their role in abiotic stress.
METHODThe CHS introns with specific primers were cloned and bioinformatic method was applied to predict the cis-elements in the intron of CHS. The introns were subcloned into binary vector, pCAMBIA-1301 before being transferred to tobacco. Then the activity of GUS of the transgenic tobacco seeds was analyzed.
RESULTSeven cis-elements were found in the introns. Under the dark and high temperature GUS expression rose at the first (3 h), but then declined (9 h). ABA and MeJA regulated insignificantly the GUS activity in normal temperature; treatment of 10% PEG induced GUS expression.
CONCLUSIONCHS introns could be play a role in the regulation of S. baicalensis phenylpropanoid biosynthetic pathway.

BACKGROUND:It is reported that bone marrow mesenchymal stem cell(BMSC)transplantation might be a promising treatment for liver fibrosis.But the mechanism is still unclear.OBJECTIVE:To observe the hepatic stellate cells apoptosis induced by BMSC transplantation,and to study the mechanism of BMSC in treating hepatic fibrosis in vivo.METHODS:CCl_4 subcutaneous injection was performed to induce rat liver fibrosis.After 8 weeks of CCU injection,20 rats which underwent successful model establishment were randomly divided into experimental group and control group,10 in each group.The experimental group received MSC transplantation via tail vein injection,and the control group were given DMEM instead.The rats were killed and the livers were harvested at three time point,the day of MSC transplantation,3 days after transplantation,and 7 days after transplantation.The hydroxyproline content was detected by HE and Masson staining,and the expression changes of α-smooth muscle actin(α-SMA)proteins were determined using immunohistochemistry.The apoptosis of hepatic stellate cells were determined by α-SMA and TUNEL(terminal dUTP nick-end labeling)dual-staining.RESULTS AND CONCLUSION:After 8 weeks of CCU injection,the hydroxyproline content increased and histology indicated progress of liver fibrosis.At 7 days after MSC transplantation,the hydroxyproline in the liver was decreased,and the liver fibrosis was alleviated in the experimental group but aggravated in the control group.Immunohistochemistry indicated that α-SMA positive cells were increased at 8 weeks after CCU injection.At day 7 after transplantation,α-SMA positive cells in the experimental group were significantly less than control group(P < 0.05).At 3 days after transplantation,the hepatic stellate cells apoptosis in the experimental group was significantly aggravated compared with control group(P < 0.05).This suggested that MSC transplant was an effective treatment for liver fibrosis.MSC inducing hepatic stellate cells apoptosis may be one of the mechanisms.
