Effect of topical application with 5, 10 and 15${\mu}$g/ml thyroxine on the pre-cocoon, cocoon, postcocoon and silk improvement were studied in bivoltine silkworm NB18 breed of B. mori L. Thyroxine was applied independently on alternate days to silkworm of IV and V instar larvae. The treatment of all different concentrations resulted in a significant increase in commercial characters like larval weight, silkgland weight, cocooning percentage, female cocoon weight and its shell weight and male cocoon shell weight and its ratio, cocoon dimension, length of the filament and its weight and oviposition. However, there was no significant change in larvel weight in 5${\mu}$g/ml treated group and larval duration was significantly decrease. But moth emergence percentage and hatching percentage did not show any significant change when compared with that of carrier control.

The purposes of this study are to calculate the green and dried weight using wood discs, to figure out weight change on air drying times, and to develop the model of wood disc weight change for Larix kaempferi, Pinus koraiensis, and Pinus densiflora. The variables affecting the weight change were investigated, and the pattern of weight change over time was figured out through linear models. When comparing the stem green weight calculated using wood discs in this study with the weight table of Korea Forest Service, the weight was not significantly different for L. kaempferi and P. koraiensis. On the other hand, in comparison of stem dried weight, the weight was significantly different in all of three species. In addition, various measurement factors were examined to figure out the relationship with weight change, and air drying times and disc diameter were found as significant independent variables. Finally, two linear models were developed to estimate air drying times of three species, fit statistics were significant for practical use.

This study was designed to compare the effect of protein with that of calorie, both of which were supplemented by separate feeding, on the recovery rate and metabolic change of undernourished rats. During the two weeks of food restriction, the weight of body and some major internal organs was reduced, compared with normal growing rats, but the extent of reduction was various. After that, recovery food was supplemented for two weeks. The amount of body nitrogen retention and its -percentage were lower in unsupplemented and sugar supplemented groups. Among the supplemented groups, its amount was increased according as the protein intake was higher, while its percentage was decreased. Body and internal organs weight change showed a similar tendency. Interrelation between calorie intake and body fat retention (liver fat content and epididymal fat pad weight) was not found regularly. Consequently, the recovery rate from restriction was higher in protein supplemented group than calorie supplemented group. But no significant difference could be found between the groups.

The purposes of this study were to evaluate the changes in hematologic indices after plateletpheresis and to identify the preapheresis platelet count and clinical factors (age, gender, height, and weight) that showed some influence on the percentage of platelet decrement, yield and efficiency. Plateletpheresis was performed on 101 healthy donors in Bundang CHA general hospital. The data was analyzed using the SAS program with t-test, ANOVA test and Multiple regression. The mean percentage decrease after plateletpheresis was 2.0% in hemoglobin, 1.8% in hematocrit, and 29.7% in the platelet count, while a WBC count showed an increase of 2.6%. The mean percentage decrease of hemoglobin and hematocrit were 1.7% and 1.4%, in males and 3.6% and 3.7% in females, respectively. Particularly the percentage decrease of platelet count was significantly higher in females (40.0%) than in males (27.2%). The platelet decrementage and yield were significantly higher in females, but the efficiency did not differ significantly between males and females. The yield showed the lowest levels in subjects who were 40 years old or over but the platelet decrement and efficiency did not change according to age. The platelet decrement increased as height and weight increased. Also, the platelet decrement and yield increased as the initial platelet counts increased, but the efficiency did not. From multiple regression analysis, the platelet decrement was associated with gender, weight, and initial platelet count. The yield was related to the initial platelet count, but the efficiency was not related to gender, age, weight, height or initial platelet counts. This study has a limitation of the generality of the study results since this study was conducted only in a single university hospital. Further study would be necessary to find out a subpopulation that is sensitive to the hematologic change after plateletpheresis, and to determine the standard criteria for blood donation based on the subpopulation.

This study was conducted to investigate the effect of planting dates using garlic bulbils for production of seed garlic. The planting dates were examined using 0.2 g bulbils of 'Namdo' or 'Danyang'. For the planting dates study conducted in the middle regions, the bulbils of 'Danyang' planted in autumn produced bulb weight ranging from 3.1 to 3.5 g and percentage of harvest ranged from 61 to 71. The bulbils of 'Danyang' planted in spring produced bulb weight ranging from 1.8 to 2.8 g and percentage of harvest ranged from 53 to 60. The most desirable planting date was in the early October for the middle regions. For the planting dates study conducted in the southern regions, the bulbils of 'Namdo' planted in autumn produced bulb weight ranging from 1.8 to 3.0 g and percentage of harvest ranged from 74 to 89. The bulbils of 'Danyang' planted in spring produced bulb weight ranging from 0.6 to 1.0 g and percentage of harvest ranged from 47 to 56. The most desirable planting date was in the mid and late September for the southern regions.

This study examined how differing triathlon durations effect weight, serum sodium concentration, and hematological levels, and investigated relationships between these variables and finishing time as well as between body weight changes and serum sodium following Ironman distance triathlons (IDT) and Olympic distance triathlons (ODT). All eight athletes successfully completed ODT and IOT. We found that the mean body weight decreased following both IDT and ODT and that serum sodium was significantly (p<0.05) increased immediately after IDT, RBC, Hb, Hct, and MCH were significantly (p<0.05) increased immediately after IDT. Hct was significantly (p<0.05) decreased immediately after ODT. MCHC was significantly (p<0.01) increased immediate1y after ODT. In IDT, the percentage of change in body weight correlated to the percentage of change in serum sodium concentrations (r=0.75, p=0.05). In conclusion, our srudy showed that serum sodium concentraion increased in IDT and maintained in ODT, despite significant body weight loss during the races. The percentage of change in body weight was related to serum sodium concentration but unrelated to performance in the triathlon. The changes of RBC, Hb, and Hct values from two different length triathlons were depending on race distance.

The research is focused on relationship between body fat percentage and physical characteristics of women in age group between 20s and 30s who experience great deal of physical change such as marriage, pregnancy, delivery, breast-feeding, and etc. The research used physical measurement of two hundreds women: 50 women in their early twenties, 50 women in their late twenties, 50 women in their early thirties, and 50 women in their late thirties. The research provides base data for women clothing industry by observing relationship between physical figure and body fat percentage rate based on obesity study on body fat percentage, physical BMI, R$\ddot{o}$hrer Index, and Vervaeck Index. Followings are conclusion of the research. The older the ages, the shorter the height and the heavier the weight. Recognizable differences in circumference, thickness, and width rather than in length are found. Also recognizable increases in average body fat percentage and average physical characteristics by age have found. By observing body fat percentage and physical measurements, it was revealed that weight has more effect on body fat percentage than height in all ages. Circumference, width, and thickness have more impact than length measurements among physical measurements. Main body or upper body has more impact than legs and arms or lower body. Body fat percentage increase rapidly by ages. 2.0% of age 20~24, 20.0% of age 25~29, 28.0% of age 30~34, and 54.0% of age 35~39 were sorted as obesity.

Purpose: This study was to investigate the correlation among body weight, body composition, delivery method, parity, weight gain during pregnancy and obesity before pregnancy of patients who received postpartum care in one oriental medicine hospital. Mothods: From September 1, 2009 to August 31, 2008, we included 34 postpartum patients who had body composition analysis when admission and discharge among 47 postpartum patients who were hospitalized and received postpartum care in $\bigcirc\bigcirc$ University $\bigcirc\bigcirc$ Hospital. We used SPSS 14.0 for window to test for statistical significance. Results: After postpartum care, body weight and BMI of mothers was significantly decreased and the weight loss was almost body water. Mothers who had cesarean section had relatively severe edema and mothers who had been overweight before pregnancy had high BMI, body fat and abdominal fat. After delivery, body fat percentage was increased highly and body weight retention lasted long in mothers who had gained over 12.5kg during pregnancy. Conclusion: Living habits including diet has a significant effect on weight change of mothers during early puerperium, therefore it is required to teach mothers about breast-feeding, diet, and exercise to help their weight return to normal.

Paecilomyces sinclairii was administered ad libitum feeding at percentage levels of 0, 1.25, 2.5, 5 and 10 percentage (calculated about 8 g/kg)/feeder for a period of 3 months. There was no observed clinical signs or deaths related to treatment in all groups tested. Therefore, the approximate lethal dose of P. sinclairii was considered to be higher than 8 g/kg in rats. Mild decreases in body weight gain were observed dose-dependently in P. sinclairii treated groups in dose response manner after 2 weeks. Interestingly, the weight of abdominal adipose tissues surrounding epididymides were greatly reduced by this Dongchunghacho, in parallel with the mild increase in body weight gain. However, the absolute weight change of other organs was not observed. There were not significantly different from the control group in urinalysis, ocular examination, hematological, serum biochemical value and histopathological examination. From these results, it is concluded that the no-observed-adverse-effect level (NOAEL) of P. sinclairii is less than 1.25% (1 g/kg) in rats in the present study.
