In prder to clarify the changes of serum chemical values(AST, CPK and LDH activities)and LDH isoenzyme fractions in frequent occuring some diseases of dairy cows, total 48 cows(40 patients: 18 with downer cow syndrome, 17 with abomasal displacement and 5 with acute mastitis and 8 controls: clinically healthy cows) were examined. The results obtained were as follows: 1. In changes of total serum enzyme activities of patients group, increase of serum AST(P<0.001), CPK(P<0.01) and LDH activities(P<0.01)were observed in groups of downer cow syndrome and abomasal displacement, respectively by comparison with control group. Increase of AST only was found in group of acute mastitis(P<0.05). 2. In LDH isoenzyme fractions, increase of LDH₁(P<0.01), LDH₂(P<0.05), LDH₃(P<0.01), LDH₄(P<0.01) and LDH_5(P<0.01)fractiona was observed in group of downer cow syndrome and also marker increase of LDH4 and LDH5 fractions was noted in this group. The increase of LDH₁, LDH₂ amd LDH₃ (P<0.01)fractions was found in group of abomasal displacement, but group of acute mastitis showed similar result to that of control group.

This study aims to examine the determinant factors of career commitment discussed in the prospective researches and investigate those factors influencing on the career commitment of police officers. Personal characteristics such as growth needs and self-efficacy showed statistically significant influential relationship with career satisfaction. On the other hand, growth needs appeared to have a significant influences on career continuance, however, there was no significant relation between self-efficacy and career continuance. In terms of job characteristics, job fitness and distribution justice presented a statistically significant association with career satisfaction and career continuance. Furthermore, as the social characteristics, perceived organizational support and work-family conflict had statistically meaningful influences on career satisfaction. For relationship between such social characteristics and career continuance, there was significant relation between perceived organizational support and career continuance but no such a relationship was revealed between work-family conflict and career continuance. This research provide upon the basis of the reuslt therein, suggestions needed for influencing relationship in career commitment of police officers.
