  • The effects of isoproterenol, a sympathomimetic amine, on the mast cells in the oral mucosa were cytochemically studied in twenty four healthy male albino rats weighing approximately 100gm. seven groups of three each were injected intraperitoneally, as a single dose of 8mg/100gm. body wt., (dissolved in 0.9% saline 0.2㎖). Each groups were sacrificed following ether anesthesia at he time indicated, 1. 2. 3. 5. 7. 10. 14days after only a single injection. One normal group is not administered with any substances. The sections of oral mucosa were stained with 0.005% toluidine blue (Mowry's method) and alcian blue (pH 2.5). We found that isoproterenol made an initial decrease in the metachromasia and alcian blue affinity, and the number of mast cell, followed by an subsequent return to normal.

  • Compensation of temperature is very important to make high precision Load Cell. In this study, we developed a new type of load cell. The structure of the load cell has four strain gauges m single surface of the load cell. Also a new temperature compensation method is proposed and these, characteristics are better than previous one. This study will offer application to other type of load cell end another sensors.

  • Force plate analysis was used to describe the effect of acupuncture on right knee osteoarthritis (OA) in a seven-year-old hound breed dog weighing 27 kg. The acupuncture treatment was performed twice a week for 3 weeks. Ground reaction forces (GRFs) and subjective clinical scores in both hind limbs were obtained prior to and 72 hours after each treatment. Right vertical peak force was increased as the dog was acupunctured. Although their sensitivity was lower than that of the GRF data, the subjective clinical scores reflected an improvement. In addition, vertical peak force of normal left hind limb was also increased during this trial. These results indicate that gait analysis may be valuable objective method in future evaluation of acupuncture for OA of the stifle joint.

  • The longitudinal changes on human milk intake of exclusively breast-fed infants(boys=15, girls=12) from 0.5 to 6 months after parturition have been studied by test-weighing method in Cheongju and Anseong area. Infant milk intake per day tended to increase during lactation. The mean intake at 0.5, 1, 2, 3, 4, 5, and 6 months were 532, 695, 734, 756, 785, 767, and 710g, respectively. The average intakes were 752 and 660g for boys and girls, respectively. The overall mean intake was 711g/day. The milk intake between boys and girls at 1, 2, 4 months, and mean value was significantly different(p<0.05). Infant milk intake had a significant positive correlation with human milk volume of lactating women, but no correlation with maternal age, weight before delivery, height, and birth weight.

  • A communal feeding program has been managed mostly by the Sae Ma Eul Women's club of agricultural cooperatives during busy days of farming in rural Korea and spreading rapidly throughout the country since a couple of years ago. Four communal feeding villages from 3 provinces in Korea were purposively selected. The food and nutrient intake of 524 participants were measured by the Precise-Weighing method for 3 days from October $7{\sim}16$ 1976. Total amount of food consumed per participant per two meal day was 1456 grams, greater than national average. Two meals that the communal feeding program provided to farmers under the intensive work of harvesting were supplying enough calories and all other nutrients except the riboflavin. There was a variation among CF villages but overall the nutrient intake was good and had balanced meals. This investigation is a part of the study on nutrition supported by a grant from USAID.

  • Purpose: This paper evaluates the reliability of tapered grid couplings and presents test results through performance and life tests. Methods: The performance and life test method were presented by analyzing the failure modes for the tapered grid coupling. Zero failure test time was calculated to evaluate the reliability of tapered grid couplings and the test was performed under accelerated conditions. The nondestructive test and wear analysis using weighing were also carried out to check the failure modes of the field conditions. Conclusion: This study can be provided to improve the product reliability through failure analysis of a tapered grid coupling. The performance test results of before and after the accelerated life test were presented to confirm the improved reliability of the tapered grid coupling.

  • Stroke volume (SV) is an important parameter for monitoring of a critically ill animal and is echocardiographically measured using the modified Simpson's method, automated contour tracking (ACT) method and left ventricular outflow method. The purpose of this study was to evaluate the effect of anesthesia (isoflurane) on the SV during echocardiographic examination and to evaluate the feasibility of ACT method for measuring the stroke volume without anesthesia (conscious state). Ten clinically healthy adult Beagle dogs (3 male and 7 female, weighing 6.6-10.8 kg, aged 2-3 years old) were enrolled. Our study found that the dogs anesthetized have a significantly lower SV, compared to the SV of dogs unanesthetized, regardless of methods measuring SV. In addition, in the dogs without anesthesia, the SV measured by ACT method was significantly lower than the other two methods. This result implies that the anesthesia may significantly lower the SV. Thus, the measurement of SV under anesthesia may not be adequate in veterinary field. Furthermore because the ACT method measured SV significantly lower than other two methods, this method may be inappropriate for measuring SV in even conscious dogs.

  • Records on weaning (3803) and yearling weight (2990) of beef cattle (Bibos banteng) from the Bali Cattle Improvement Project were examined. A mixed model analysis involving all main non-genetic effects (village, year of birth, season of birth, age of dam, sex of calf, all significant interactions and age at weighing as a covariate) as fixed effects and sire nested within village as a random effect was undertaken. Variance components were estimated by Henderson's Method III. Paternal half-sib components of variance and covariance were used to estimate heritabilities of weaning and yearling weights, as well as their genetic and phenotypic correlations. Heritability estimates ($\pm$ standard error) obtained by Henderson's Method III for weaning and yearling weights were $.11{\pm}.03$ and $.13{\pm}.04$, respectively while the phenotypic and genetic correlations were estimated as .32 and $.64{\pm}.10$, respectively. The parameters estimated in this study were at the lower end of the range of reported values from various breeds. It is concluded that further information should be gathered to assist in estimating genetic parameters for other economic traits of Bali beef cattle and to provide more accurate estimates for weaning and yearling weights. These parameters should then be used to formulate a selection program to enable the genetic improvement of Bali Beef cattle.

  • In an attempt to solve multiobjective optimization problems, weighted sum method is most widely used for the advantage that a designer can consider the relative significance of each object functions by weight values but it can be highly sensitive to weight vector and occasionally yield a deviated optimum from the relative weighting values designer designated because the multiobjective function has the form of simple sum of the product of the weighting values and the object functions in traditional approach. To search the design solution agree well to the designer's weighting values, we proposed new multiobjective function which was the functional of each normalized objective functions and considered to find the design solution comparing the distance between the characteristic line and the ideal optimum. In this study, proposed multiobjective function was applied to design high efficiency and low noise axial flow fan and the result shows this approach is effective for the case that the quality of the design can be highly affected by the designer's subjectiveness represented as weighting values in multiobjective design optimization process.
