The effects of intensity and duration of aerobic exercise on spatial memory function in male Wistar rats

BACKGROUND Memory is a vital function of the brain. Aerobic exercise has a positive
effect on memory’s function, but the appropriate combination of intensity and duration
of aerobic exercise is still unknown. This study was aimed to investigate the effect of
optimum combinations of intensity and duration of aerobic exercise on spatial memory
function.

EXOGENT FACTORS AT PT. METRO TARUNA JAKARTA THAT AFFECT EMPLOYEE PERFORMANCE

This study aims to determine the effect of training and work discipline as exogenous factors on employee
performance at PT Metro Taruna Jakarta. The 82 respondents as a sample and data analysis and process
techniques used are validity, reliability, descriptive analysis, normality test, multicollinearity test,
heteroscedasticity test, autocorrelation test, multiple linear regression analysis, simultaneous test,
coefficient test, and correlation coefficient of determination. Based on the results of data processing
Correlation and Determination Coefficients, the nature of the relationship between training, work
discipline and employee performance is affected, because the correlation coefficient is 0.910 and the
coefficient of determination r2 = 0.824 or 82.4%, meaning 82.4% variation or change in employee
performance variables is the contribution of the influence of training and work discipline variables, while
the remaining 17.6% is contributed by the influence of other factors such as compensation, workloads that
are not comparable to payments, lack of motivation, high levels of work stress, low levels of promotion and
others.
