This study was conducted to provide the information for the carcass grading properties of imported beef cattles fed in Korea. The cattles from 4 different breed such as Hereford, Angus, Murray Grey, Hereford${\times}$Angus were imported and slaughtered at 700kg(24 month). The Yield and Quality grading characteristics for 10 cattles from each breed were evaluated. Carcass weight of Murray Grey was lower than the other breed(p<0.05). The thickness of backfat was the lowest for Hereford(13.7mm) and followed by Hereford${\times}$Angus(17.30mm), Angus(18.20mm) and Murray Grey(18.90mm). Hereford had the highest Yield index(64.63%) and Murray Grey had the lowest Yield index(62.43)(p<0.05). The frequency percentages of marbling degree for Angus having the 1++ over degrees were 50% which was the highest among the breed. In the frequencies of final carcass grades, Hereford produced 30% of B grade and 70% of C grade in Yield grade and the 3 grade produced in Quality grade. All carcasses of Angus were graded as the grade C in Yield grade and 20% carcasses of Angus had the 2 grade and 80% carcasses had the 3 grade in Quality grade. Murray Grey produced 10% of grade B and 90% of grade C in Yield grade and produced 10% of the 2 grade and 90% of the 3 grade in Quality grade. The Hereford${\times}$Angus produced 100% of grade C in Yield grade and 100% of the 3 grade in Quality grade.

$^{99m}Tc-galactosyl$ human serum albumin (Tc-GSA) is a radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically present in the hepatocyte membrane. Because these receptors are decreased in hepatic parenchymal damage, the degree of Tc-GSA accumulation in the liver correlates with findings of liver function test. Hepatic images were performed with Tc-GSA in patients with acute hepatic dysfunction by Amantia Subjunquillea poisoning, and compared with these of liver ultrasonography (USG). Tc-GSA (185 MBq, 3 mg of GSA) was injected intravenously, and dynamic images were recorded for 30 minutes. Time-activity curves for the heart and liver were generated from regions of interest for the whole liver and precordium. Degree of hepatic uptake and clearance rate of Tc-GSA were generated by visual interpretation and semiquantitative analysis parameters (receptor index : LHL15 and index of blood clearance : HH15). Visual assessment of GSA scintigraphy revealed mildly decreased liver uptake in all of subjects. The mean LHL15 and HH15 were 0.886 and 0.621, graded as mild dysfunction in 2, and mild to moderate dysfunction in 1 subject. In contrast, liver USG showed no remarkable changes of hepatic parenchyme. Tc-GSA scintigraphy was considered as a useful imaging modality in the assessment of the hepatic dysfunction.

This study focused on establishing a natural rainwater circulation system using rainwater meant for relatively large urban development projects such as a new town development. In particular, when the location selection techniques for individual elements of a natural rainwater circulation system are developed for the integrated rainwater management, changes in hydrological environment will be minimized and the natural water circulation would be restored to realize the low impact development (LID). In that case, not only the excess will be reduced but water space and green areas in a city would also increase to improve the urban sustainability. First of all, there were five elements selected for the location selection of a rainwater circulation system intended for the integrated rainwater management: rainwater collection, infiltration, filtration, retention and movement spaces. After generating these items, the location selection items and criteria were defined for each of the five elements. For a technique to apply the generated evaluation items and criteria, a grid cell analysis was conducted based m the suitability index theory, and thematic maps were overlapped through suitability assessment of each element and graded based on the suitability index. The priority areas were identified for each element. The developed technique was applied to a site where Gim-cheon Innovation City development is planned to review its feasibility and limitations. The combined score of the overlapped map for each element was separated into five levels: very low, low, moderate, high and very high. Finally, it was concluded that creating a rainwater circulation system conceptual map m the current land use plan based on the outcome of the application would be useful in building a water circulation system at the de1ailed space planning stage after environmental and ecological planning. Furthermore, we use the results of this study as a means for environment-friendly urban planning for sustainable urban development.

The purpose of this study was to investigate the health status of preschool children using the questionnaires about dietary behaviors and anthropometric indices. And also nutritional status was investigated using questionnaires for 24-hr recall method. The study was conducted in 145 children aged 3 to 6 years and questionnaires for dietary behaviors and dietary intakes were performed by mothers of children in Ulsan. Just nine percent of children were graded as good in terms of having healthy eating habits, this means that the nutrition education for the dietary behaviors should be more focused on preschool children. With regard to the frequency of food intake, children consumed green & yellow vegetables less frequently, meanwhile consumed high protein source food (meat, egg and bean) and milk and its product more frequently. Children almost never consumed fried foods as often as 1-2 times a weak. In assessment of the health status, children have the highest prevalence of colds and allergy, but lower prevalence of clinical symptoms due to the nutritional deficiency. The mean height was $103.6\;{\pm}\;6.4\;cm$ and significantly different among age (p < 0.05), but was not significantly different between sex. The mean weight was $17.8\;{\pm}\;3.0\;kg$ and significantly different in 5, 6years old among age. By the WLI criteria, 11.1% of children were underweight and 17.4% of children were overweight or obese. By the Rohrer index criteria, any children were not underweight and 86.8% of children were overweight or obese. By the Kaup index criteria, 2.8% of children were underweight and 29.2% of children were overweight or obese. And Obesity Index criteria, 2.1% of children were underweight and 20.8% of children were overweight or obese. The results of obesity rate by all criteria except Rohrer index indicated similar level, were significantly high in age 3 with all criteria, and decreased with age increased. The energy intake of children was lower than EER (Estimated Energy Requirements) of Dietary Reference Intakes for Koreans (KDRIs) by as much as 85.7%. Acceptable Macronutrient Distribution Ranges (AMDR) was 62.6:21.5:15.7 as carbohydrate:protein:lipid, so children consumed protein more, but consumed lipid less compared with those of KDRIs. Vitamin A intake was 133% of recommended intakes (RI) and calcium intake which was identified as the nutrient most likely to be lacking in diets was 98.9% of RI. The intakes of all minerals and vitamins except folate were higher than KDRIs. 33.3% of children were distributed in insufficiency of energy intake, 42.7% of children were distributed in insufficiency of lipid intake. These results indicate that the need of developing of nutrition education program and further concern of a public health center, university and children care center about dietary life for preschool children.

Objectives : This study was designed to compare the effects on Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), 36-ltems Short-Form Health Survey(SF-36), Visual Analog Scale(VAS) and Nine Point Scale between 'Intramuscular Bee Venom Herbal Acupuncture' and 'Intracutaneous Bee Venom Herbal Acupuncture' in knee osteoarthritis patients for 4weeks. Methods : All the voluntary subject were diagnosed as knee osteoarthritis. Patients were randomly assigned either to two groups : Intramuscular bee venom herbal acupuncture treatment group(IM-BV group) or Intracutaneous bee venom herbal acupuncture treatment group(IC-BV group). The IM-BV group received bee venom herbal acupuncture intramuscularly on muscles closest to the pathologic site on ultrasonography. The IC-BV group received bee venom herbal acupuncture intracutaneously on $LE_{110}$, $LE_{201}$, $ST_{35}$, $ST_{36}$ and $LR_8$. Bee venom herbal acupuncture was applied twice a week for 4 weeks by an oriental medical doctor at Kyung-hee Oriental Medical Hospital. Both groups were checked of pathologic site by ultrasonography before treatment and follow up after four-week treatment. The patients were assessed by KWOMAC and SF-36 before and after four-week treatment. The changes in patients' pain was measured by VAS before treatment and after one-, two-, three- and four-week treatment. The patients' overall treatment outcome assesment was measured by Nine Point Scale after four-week treatment. Results : The results were as follows ; 1. The IM-BV group showed significant improvement on total, pain, stiffness and physical function in KWOMAC, and the IC-BV group showed significant improvement on total and physical function in KWOMAC after 4weeks compared to the pre-treatment. In KWOMAC, the IM-BV group showed more improvement on average compared to the IC-BV group, but there were no significant difference between two groups. 2. The IM-BV group showed significant improvement on VAS after one-week treatment. The IC-BV group showed significant improvement on VAS after two-week treatment. But there were no significant difference between two groups. 3. The IM-BV group showed significant improvement on physical functioning(PF) and bodily pain(BP) in SF-36, and the IC-BV group showed significant improvement on vitality(VT) and bodily pain(BP) in SF-36 after 4weeks compared to the pre-treatment. But there were no significant difference between two groups. 4. 88.2% of IM-BV group and 93.3% of IC-BV group graded their improvement as 'Fair' or better on Nine Point Scale. But there were no significant difference between two groups. Conclusions : This study suggests that in the treatment of knee osteoarthtitis patients, effects of 'Intramuscular Bee Venom Herbal Acupuncture' were not different from 'Intracutaneous Bee Venom Herbal Acupuncture' statistically. But both treatment showed effects on pain and physical function in knee osteoarthtitis patients.
