Total CPK activities and CPK isoenzymes fractions of the sera and tissues were examined to obtain the physiological basic data of ruminant available in veterinary clinical practice. For the sera total CPK activities and CPK isoenzymes fractions, total 39 clinically healthy Korean native goats (3 to 10 months old, IS of female and 18 of male) and 6 of Korean native goats (1 to 2 years old, 3 of female and 3 of male) were used. Seventeen Korean native cattle (3 to 6 years old, 10 of female and 7 of male) and 27 Holstein-Friesian cattle (2 to 8 months old, 7 of female and 3 to 12 years old, 20 of female) were also examined for the sera total CPK activities and CPK isoenzymes fractions. For the total CPK activities and CPK isoenzyme fractions, 3 of female Korean native goats (7 months old), 3 of female Korean native cattle (2 years old) and 3 of dairy cattle (2 years old, 2 of female and 1 of male) were used. The tissues examined were the cerebrum (2 of Korean native cattle), spinal cord (1 of Korean native cattle), heart, lung, diaphragm, reticulum, liver, spleen, kidney, jejunum. colon and femoral muscle. The results obtained were as follows : 1. In Korean native goats less than 1-year-old. serum total CPK activities were 67.8${\pm}$17.7(39.0~96.5) IU/$\ell$ in female and 63.4${\pm}$19.0(28.7~94.4) IU/$\ell$ in male. Further they were 67.0${\pm}$5.3(59.5~70.7) IU/$\ell$ and 54.5${\pm}$11.1(39.1~69.4) IU/$\ell$ in female and male Korean native goats over 1-year-old, respectively. Serum total CPK activities of female were slightly higher than those of male. Significance between age and sex was not found. 2. Serum total CPK activities were 56.8${\pm}$19.7(27.6~90.5) IU/$\ell$ and 65.6${\pm}$10.8(52.8~78.0) IU/$\ell$ in female and male Korean native adult cattle, respectively, Serum total CPK activities of male were slightly higher than those of female, but they were not significant 3. Serum total CPK activities we,e 72.5${\pm}$8.2(57.2~83.2) IU/$\ell$ and 60.8${\pm}$12.5(42.7~80.6) IU/$\ell$ in calves and adult of dairy acttle, respectively. Serum total CPK activities of calves were significantly higher than those of adult(p<0.05). 4. In Korean native goats less than 1-year-old, serum CPK isoenzymes fractions were high with decreasing order of MM>MB>BB and MM>BB>MB in female and male, respectively. Further they were high with decreasing order of MM>MB>BB and MM>B8>MB in female and male Korean native goats over 1-year-old, respectively. The main fractions of CPK isoenzymes were MM in sera of Korean native goats. 5. Serum CPK Isoenzyme fractions were high with decreasing order of MM>MB>BB In both female and male of Korean native cattle. The main fraction among them was MM. 6. Serum CPK isoenzymes fractions were high with decreasing order of MM>BB>MB in both calves and adult of dairy cattle. The main fraction among them was MM. 7.

To develop more reliable diagnostic measures for traumatic pericarditis in ruminant, fluctuations of serum total LDH activities and LDH isoenzymes fractions were investigated in artificially induced pericarditis of Korean native goats. Experimental group showed the tendency of increase serum LDH total activities. Effect of LDH isoenzymes on serum total LDH activities were high with decreasing order of LDH$_1$> LDH$_3$ > LDH$\sub$5/ > LDH$_2$ > LDH$_4$ and LDH$_1$ was the hightest among them. From these findings, increase of serum total LDH activities and LDH$_1$ fraction was thought to be important in traumatic pericarditis.

In order to clarify the significance of serum CPK for the diagnosis of the cardiac disease in ruminant, the fluctuation of serum total CPK activities and CPK isoenzyme fractions was examined before and after operation in Korean native goats with artificially induced cardiac injury. In the change of serum total CPK activities, those of experimental group were changed with higher values than those of control group and significant increase was found on 2-week after operation(P<0.05). In the fluctuation of serum CPK isoenzyme fractions, significant increase of both CK1 and CK3 fractions was observed on 2-week after operation in experimental group(P<0.05), but significant difference was not found in CK2 fraction between experimental and control groups. From these findings, it is considered that taking note of increase of not only serum total CPK activities but also CK1 and CK3 fractions is important for the diagnosis of traumatic cardiac disease in ruminant.

현재 구조용 세라믹에 대한 연구는 여러 가지 작동 조건에 의해 도출된 마멸 데이터를 정량적으로 제시하고 이들의 마멸기구의 변화가 일어나는 사용 조건의 시점을 파악하였다. 이 전의 연구들은 주로 동질 재료까지 마찰 마멸 실험으로 제한되었다. 그러나 상대 운동하는 세라믹 재료들의 특성 상기계적, 화학적 물성차이에 의해 마멸 기구와 트라이볼로지적 거동(마찰계수, 마멸율)등이 다르게 나타날 확률이 높다. 이에, 본 연구에서는 볼 온 디스크 마멸 실험을 통해 여러 가지 작동환경에 따라 서로 상대 운동하는 세라믹의 재료를 달리하며 실험 하며 다른 세라믹 재료간의 트라이볼로지적 특성을 고찰하였다. 지르코니아 시편에 대해 지르코니아, 알루미나, 실리콘카바이드 3종의 상대재를 사용하여 속도와 하중조건을 변화하여 마멸실험을 수행한 결과, 지르코니아-실리콘카바이드 조합의 실험에서 저마찰 저마멸 트성이 나타났다. Currently, the study on structural ceramic helps to suggest the precise data of friction and wear in accordance with the various conditions in operations. Also, the study helps to predict effective operating conditions by monitoring the occurrence of wear transition. The studies in the past were mainly concentrated in using identical materials. However, it is highly likely to have unqualified data from the differences of mechanical and chemical properties between ceramic materials. Thus, in this study, through conducting the ball-on-disk type wear testing, the different ceramic materials has been used to consider tribological characteristics between different ceramic materials. We conducted the wear test by using three kinds of specimen which are zirconia, alumina and silicon carbide against zirconia. We have changed the sliding velocity and the loading conditions in this test and found out that there is row friction coefficient and wear rate in the combination of zirconia and silicon carbide.

The sliding wear behavior of ZrO₂-22wt%MgO (MZ) and ZrO₂-8wt%Y₂O₃(YZ) deposited on a casting aluminum alloy with bond layer (NiCrCoAlY) by plasma spray against an SiC ball was investigated under dry test conditions at room temperature. At all load conditions, the wear mechanisms of the MZ and the YZ coatings were almost the same. The wear mechanisms involved the forming of a smooth film by material transferred on the sliding surface and pullout. The wear rate of the MZ coating was less than that of the YZ coating. With an increase normal load the wear rate of the studied coatings increased. The SEM was used to examine the sliding surfaces and elucidate likely wear mechanisms. The EDX analysis of the worn surface indicated that material transfer was occurred from the SiC ball to the disk. It was suggested that the material transfer played an important role in the wear performance.
