In the present study, first, I took a general view of the Health-Related Quality of Life. Next, I describe about the HRQOL-20, which the author et al. developed in order to measure a patient's general HRQOL, and suggest that personality type, in terms of the Eysenck Personality Questionnaire, is a possible mediating factor modulating the HRQOL-20 questionnaire responses and the outcome measure, HRQOL.
When we select No students from N applicants using a result of an entrance examination, which consists of two step selection, the primary test and the secondary test. It is important to evaluate the contribution of each test. Swap-Rate is one of the measures of the contribution of stage test, and it is widely used. In this paper, first we describe a population swap-rate and sample swap-rate. Next, we consider the distribution of applicants from the point of view of swap of pass or fail. Finally, we introduce our system“SRAS: Swap-Rate Analysis System”, that can analyze the examination data on such point of view.
