Purpose: This study conducted a Monte Carlo simulation to deal with the issues of alternative methods to replace the composite scores, which were the integrated scores of indicators, with a measurement model for testing in order to solve the problems with model estimation in a research that applied SEM. Methods: The investigator directed the simulation to compare the estimated structural coefficients from the original model containing with those in the reduce model that was replaced with the composite scores or integrated scores of those indicators. The simulation was carried out in three cases according to the organizational methods of composite scores that considered the correlation coefficient and factor loading characteristics of indicators. Results: first, the invariance of the estimated structural coefficient wasn`t maintained when the factor coefficients of indicators were heterogeneous in case of a unidimensional structure among indicators. Secondly, a structural coefficient was underestimated regardless of heterogeneity among indicator factor coefficients in case of a multidimensional structure among indicators. The study also showed the effects of composite scores on the estimation of structural coefficients by comparing their estimation results according to the sample size of analysis data in each experiment.

The purpose of this study is to examine the effects of regular exercise done in the past on the improvement of vascular compliance and provide specific data that regular exercise is a positive factor for vascular health by comparing vascular compliance changes before and after 12 weeks of aerobic exercise between elite athletes who have exercised for many years and ordinary people. 10 retired athletes who have more than 5 years of track record and no regular exercise for more than 3 years after retirement and 13 people who have not regularly exercised for more than 3 years were selected as the subjects of this study. For a period of 12 weeks, the 10 people in the exercise-experienced group and 13 people in the control group, selected as above, conducted 70-minute-aerobic exercise on a treadmill for 3 times a week with a rate of perceived effort less than 17. PASW 18.0 statistical program was used to calculate the mean and standard deviation of each item from the collected results. For the general characteristics of the subjects, descriptive statistics were performed and repeated measure ANOVA was also carried out for the effectiveness of experimental treatment on the exercise-experienced and control groups. The significance level was verified near at p<.05 The results showed that the vascular compliance values of the left hand, right hand, left foot and right foot of both of the control group and exercise-experienced groups was increased after 12 weeks of exercise. Hypothesis testing of each item revealed that there is no statistical significance in all parts of left hand, right hand, left foot and right foot. However, statistical significance was found in left foot (F=29.9769, p<.001) and right foot (F=33.058, p<.001) by hypothesis testing between items. In addition, positive changes of vascular compliance were observed to progress faster in the exercise-experienced group compared to the control group.

This research aims to discuss about statistical analysis and research analysis on the results of research in natural sciences. Natural sciences round up human, animal, and etc. as its subject. These sciences make huge investments in terms of time and finance to draw results based on experimental designs. But even after preparing excellent experimental design, conducting experiments, and drawing results, the characteristics of variable and purpose of the study must he melted into the research result in order to obtain good research results. Based on these points, this research discussed whether it is better to consistently take the result of statistical analysis only or to analyze the result based on the research circumstances (theoretical and empirical). Unlike humanity and social Sciences, most of the variables in the natural sciences are directly measured based on experimental designs and there are limited number of cases available. Also there are many cases which do not satisfy the requirements for parametric statistics. Different from humanity and social sciences, each research subject in the analysis of the natural sciences possesses meanings and significance. Therefore the characteristics of the subject and the characteristics of variables must be considered in the result analysis. For this matter, guidelines for analysis, professionalism of the researchers, and enough knowledge about statistics are necessary.
