- The purpose of this study is to provide basic data for preventing preterm delivery in the aspects of blood pressure and hematic parameters. The blood pressure, hematic parameters, relationship between hematic parameters and nutritional intakes and pregnancy outcomes were compared between a preterm delivery group and a normal term delivery group. The results obtained are summarized as follows. Diastolic blood pressure was statistically higher in the preterm delivery group. White blood cells (p < 0.005) and alanine amino transferase (p < 0.05) of 3rd trimester in pregnancy were statistically higher in the preterm delivery group. Alkaline phosphatase (p < 0.0001) and lactate dehydrogenase (p < 0.05) were statistically lower in the preterm delivery group. Inverse relationships between niacin, vitamin B6 and zinc intakes and bilirubin (p < 0.05) were shown. Vitamin A intakes (p < 0.05) were significantly negatively correlated with blood protein, but zinc intakes (p < 0.05) were significantly positively correlated with blood protein. Vitamin B6 intakes (p < 0.05) were significantly negatively correlated with blood albumin. Calcium intakes (p < 0.005) and iron intakes (p < 0.05) were significantly positively correlated with blood lactate dehydrogenase. Also, vitamin A intakes (p < 0.05) were significantly positively correlated with blood glucose. Normal spontaneous vaginal delivery (p < 0.005) was statistically lower in the preterm delivery group. Birth weight (p < 0.0001) and birth length (p < 0.005) of the neonates were all statistically lower in the preterm delivery group.

- Inadequate nutritional status of pregnancy can cause underweight and premature birth, undergrowth and deliverance of physically and mentally defected babyies. The purpose of this study is to provide guidelines for preventing preterm delivery in the aspect of nutritional factors. The nutrient intakes were compared between a preterm delivery group and a normal term delivery group to recognize risk factors of preterm delivery. The results obtained are summarized as follows. The pregnancy period was statistically longer in the normal term group (p < 0.0001). Weight increase was statistically higher in the normal term group (p < 0.0001). Calories (p < 0.05), carbohydrates (p < 0.0005), dietary fibers (p < 0.0001), potassium (p < 0.0005), vitamin B1 (p < 0.0005), vitamin B6 (p < 0.05), vitamin C (p < 0.0001), and folic acid (p < 0.05) intakes were statistically higher in the normal term group. Nutrient density of vitamin B1 (p < 0.05) and vitamin C (p < 0.0001) in the normal term group was statistically higher. Nutrient adequacy ratio of zinc (p < 0.05), vitamin B1 (p < 0.05) and folic acid (p < 0.05) were statistically higher in the normal term group. Index of Nutritional Quality of vitamin B1 (p < 0.05) and vitamin C (p < 0.0001) were statistically higher in the normal term group. In this study, the normal term delivery showed higher intakes of calories, carbohydrates, dietary fiber, crude fiber, potassium, vitamin B1, vitamin B6, vitamin C and folic acid than the preterm delivery group. Deficiencies in various nutrients may lead to preterm delivery, therefore, balanced nutrient intake is recommended to prevent preterm delivery.

- The objective of this study is to investigate how patients satisfaction are affected by satisfaction with the patient menu and differentiated service resulting from QI activities and to evaluate the efficiency of QI activities. In order to improve satisfaction with menus through QI activities, this study strengthened meal round, examined the quantity of food waste produced by patients, diversified one-dish menus and used seasonal food as much as possible to reflect patients' tastes to the maximum. With regard to cooking, additionally, it strengthened sampling and standardized recipes to maintain the constancy of taste and cooking/seasoning. From July 2003, dining time was changed from 08 : 00 to 07 : 30 for breakfast and from 17 : 30 to 18 : 00 for dinner. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows: The goal of QI was to improve food service by raising the score of "Satisfaction with Offered Menus" from 3.49 before QI to 3.55 after QI and differentiating nutrition service at the VIP ward. The score of "Satisfaction with offered menus" after QI was 3.56, and services related to the VIP ward were 7 dishes per meal, meal round once per day and the use of a napkin for a spoon in setting the table. In addition a variety of dishes were used in order to heighten the visual effect. Among the 10 items included on the patient satisfaction questionnaire, 8 items showed higher scores before QI. "Taste of meals" (p <0.05), "Satisfaction with offered menus" (p <0.05), "Kindness of meal serving assistants" (p <0.05) and "Cleanliness of clothes & features" (p <0.05) of VIP ward were significantly higher than those of a general ward.

- The purpose of this research which, surveyed target hospitals, was to evaluate job operations by surveying the influences of Quality Improvement (QI) activities in various divisions related to a decrease in their back-up orders. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows : Before QI there were 147 cases of back-up orders ; after QI there were 83 cases, decrease of 64 cases. This was 44%, less than the projected goal of 50%. For each item, there was a decrease of 40 nurse cases, 9 patients and patron cases, 9 test.surgery. deliverly cases and 5 doctor cases after QI. The registering of midnight meals was not shown after QI, due to the Order Communication System (OCS) settlement. After performing QI, the average manual operation per month was reduced from 840 minutes to 498 minutes, of which the difference was 342 minutes, and the average of 342 minutes per month could be used for the peculiar operation of each division. This QI activity provided a good opportunity for establishing cooperation among divisions in providing meals to patients through interactions among divisions. It was recognized that these interactions were effective only when medical services were achieved through organized cooperation among divisions. Among the 7 items included on the patient satisfaction questionnaire, "satisfaction with offered menus" (p < 0.01) showed significantly higher scores before QI. However "satisfaction with meal times" (p < 0.01) showed significantly lower scores before QI.

- The purpose of this study was to assess how the changes in the food services environment on patients satisfaction with the hospital food service. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows: The flow line and environment of the food services in the hospital were improved through remodeling, which included the replacement of all cooking utensils, ventilation facilities and material storages, the purchase of a combi steamer, and the change of meal carts and trays. After the remodeling, the hospital food service was improved so that it provided spoons at each meal, diversified the menu utilizing the combi steamer, served event meals three times a week as well as water boiled with burned rice in the morning twice a week. In addition, various types of tableware were used in the table settings to produce attractive visual effects. Among the 10 items included on the patient satisfaction questionnaire, "satisfaction with offered menus" (p<0.01) showed significantly higher scores before the remodeling. "cooking/seasoning of food", "amount of meals" and "taste of meals" were not statistically significant, but showed increased satisfaction after the remodeling. However "temperature of food", "cleanliness of clothes and features" and "satisfaction with meal times" were not statistically significant, but showed decreased satisfaction after the remodeling.

- The purpose of this study was to investigate the difference of general characteristics, menopause status, dietary patterns and nutrient intakes between women aged from 30 to 65 years old with a hypercholesterolemia group and normocholesterolemia group. The subjects were classified as belonging to the hypercholesterolemia group or normocholesterolemia group barred on The Guidelines for Korean Hyperlipidemia. Dietary intakes of fatty acids were measured by means of a 24-hr recall method with food models and measuring tools. We analyzed both data sets together using analysis of variance chi-square test and student's t-test(SPSS for WINDOWS, version 7.5). Significance was defied as a p value< 0.05. The results obtained are summarized as follows. Mean age and BMI of the hypercholesteroemia group were significantly higher than those of the normocholesterolemia group. Intakes of cereal, vegetables, mushrooms and sea food in the normocholesterolemia group were significantly higher than those in the hypercholesterolemia group. Most of the nutrient intakes were not significantly different between the normocholesterolemia group and the hypercholesterolemia group. However, vitamin E intake of the normocholesterolemia group was significantly higher than that of the hypercholesterolemia group. There was a significant negative correlation between vitamin E intake and serum TC(r = -.363, p<0.001) and LDL-C(r = -.359, p<0.001). In addition, Serum TG had significantly correlation with carbohydrate(r = 0.137, p<0.001) and vitamin E intake(r = -0.134, p<0.001). Therefore, women who suffered from hypercholesterolemia were recommended to control body weight, and to consume foods containing high vitamin E and foods containing high dietary fiber such as vegetables, mushrooms, and sea food.
