The effects of branched chain amino acids added to a diet on changes in the body weight with or without liver, moist and dry liver weight, protein, DNA, $^3H-thymidine$ incorporation into DNA, ana mitotic index of regenerating liver were studied in partial hepatectomized rat. Experimental diet was a 14.63% casein diet supplemented with 1.49% L-leucine, 0.90% L-isoleucine and 0.98% L-Valine, and control diet was an 18.0% casein. In both diets, 2.54% nitrogen were included. Rats fed experimental diet were significantly increased body weight with or without liver 7 days, and regenerated weight of dry liver and an index of liver regeneration 5 days after partial hepatectomy. Mitotic index, contents of protein and DNA increased in regenerating liver after partial hepatectomy was higher in experimental diet group. This results suggest that branched chain amino acids have an benefitial effect on whole body as well as liver regeneration after partial hepatectomy in rat.

The purpose of this paper is to analyze theoretically and empirically spillover effects of fishery quota on related markets through their demand curves. Theoretically, the spillover effects of a change in quota can be captured through the directly distorted market alone by computing surpluses associated with the new and old equilibrium. This study estimates empirically demand functions in the context of both the partial equilibrium and general equilibrium. The spillover effect can be computed from the difference between these two estimates. The econometric methodology to estimate the demand curves in the context of general equilibrium is presented and illustrated. The empirical result of fishery markets shows that spillover effects transmitted across other markets are not small and approximately account for 43.3% of the partial equilibrium welfare effects.

This study is to investigate the effect of a domestic pottery stone as a batch inclusion on the synthesis of porcelain bodies and their physical properties. The basic composition of porcelain bodies studied was consisted of 50wt% kaolin, 25wt% feldspar and 25wt% quartz. The inclusion of pottery stone was performed by partial substitution for either quartz or feldspar up to 25% of the total weight of batches. Sixteen porcelain bodied different in batch composition were prepared by firing them in the temperature range from 110$0^{\circ}C$ to 135$0^{\circ}C$ and their physical properties and microstructures were carefully examined. It was found that the inclusion of pottery stone could reudce the firing temperature for vitrification up to 5$0^{\circ}C$ but appreciably decreased the mechanical strength of sintered bodies. The most faborable result could obtain with partial substitution for both quartz and feldspar at same time up to 25% of the total batch weight.

A group of Hanwoo (Korean cattle) steers (n=14,386) was sampled from a commercial abattoir located in Seoul over one year period (spring, summer, autumn and winter) and their carcass traits were collected. Carcass traits assessed by an official meat grader comprised degree of marbling, meat color, fat color, texture and maturity for quality grade, and back fat thickness, ribeye area and carcass weight for yield grade. A heavier carcass with a higher marbling score, more red meat color and white fat color received better quality grade (p<0.05). Regression analysis showed that the marbling score was the strongest attribute (partial $R^2=0.88$) for quality grade. Lighter carcasses with a thinner back fat and larger ribeye area received higher yield grade score. The back fat thickness was the most negative determinant of yield grade (Partial $R^2=-0.66$). The slaughter season had a little effect on quality and yield grades. As slaughter weight increased, back fat thickness and ribeye area increased linearly, whereas marbling score reached its asymptotic level at approximately 570 kg. As a consequence, quality grade showed a considerable improvement up to 570 kg, but increases in slaughter weight afterward showed a little benefit on quality grade. There was a clear curvilinear relationship between slaughter weight and yield grade in that the yield grade reached its highest point at approximately 490 kg and decreased afterward. These results suggested that 570kg at the age of 24 months might be the economic slaughter weight for quality grade but 490 kg for yield grade.

This study was performed to investigate the best surgical technique for normal stifle mobility by comparison with clinical signs and histopathological changes of articular cartilage after femoral trochleoplasty, trochlear chondroplasty and trochlear wedge recession. Twelve small mixed dogs who had grade I or II medial patellar luxation were used. The days that the dog had partial and full weight bearing were checked and histopathological changes 49 and 90 days after surgery were observed. The dogs had partial weight bearing in 3~6 days postoperatively and full weight bearing in 20~24 days. After femoral trochlepoplasty, the articular surface was irregular and rough, but smooth after trochlear chondroplasty and trochlear wedge recession. Histopathologic examination performed on the 49th and 90th days after femoral trochleoplasty revealed that articular surface was occupied by fibrocartilage but the hyaline cartilages are preserved after trochlear chondroplasty and trochlear wedge recession. In trochlear wedge recession, the wedges of all cases were firmly attached to underlying subchondral bone which were indicating complete healing. The results of this study suggested that the trochlear wedge recession was the best chondroplasty for correcting patellar luxation.

The tribological characteristics of dental metal alloys and zirconia were studied by carrying out a friction and wear performance test. In this study, a pin-on-disk-type tester was used and dead weight was employed as the normal load applied to the test specimen. The friction coefficient of dental metal alloys was investigated in terms of their weight and sliding velocity. Microscopic observations were carried out on worn surfaces of specimens. The results indicated that among all metal alloys, Super-A had the highest friction coefficient. Super-A had the lowest amount of wear among all metal alloys, and the amount of wear increased in the following order: Crown & Bridge, Porcelain, and Partial. Crown & Bridge had the best friction coefficient, but the hardness of Crown & Bridge was lower than that of Porcelain and Partial. Experimental measurement results indicated that the disk weight before and after the experiment was the same.

Purpose : We investigated the effects of the combined use of FES and over ground walking with partial body-weight support (PBWS) on walking function and balance control in people with chronic strokes. Methods : Twenty-seven people who were ambulatory after chronic strokes were evaluated. The exercise's intervention consisted of the combined use of FES and over ground walking with PBWS and general exercise groups. The FES + PBWS group and general exercise group consisted on a-20-minute session per day, 3 times a week during a 4 week period. The evaluation was carried out before, after, and two weeks after the exercise intervention. Outcome measures were a 6 Minute Walk Test, 6-Meter walk Test, Timed Up and Go Test, and a Balance Test, measured before and after the exercise interventions at a-2 week follow up. Results : The endurance was significantly increased in both the FES+PBWS group and general exercise group (p<0.05). Significant increase on the gait velocity was observed in both the FES+PBWS group and general exercise group (p<0.05). The TUG was significantly different in both the FES + PBWS group and general exercise group (p<0.05). However there were no differences in both the between-group & interaction. The stability index was significantly different in both the FES + PBWS group and general exercise group (p<0.05). Conclusion : In conclusion, the combined use of FES and over ground walking with PBWS led to an improvement in walking function and balance control. Thus, it is possible to combine the use of FES and over ground walking with PBWS for physical therapy intervention to improve walking function and balance control. It is suggested to apply this intervention in the clinical field.
