현행 대학수학능력시험에서는 영역별로 선택과목제가 본격적으로 도입되어 시행되고 있으며, 과목별 난이도의 차이를 사후적으로 보정하기 위하여 표준점수제를 도입하여 운영하고 있다. 그러나 표준점수제를 실제 운영해본 결과 적지 않은 문제점들이 드러난바 있다. 이 연구에서는 이러한 표준점수제의 문제점을 집중 분석해 보고, 이에 대한 대안으로 가산점수제를 제안하여 지난 2005 수능 결과에 적용해 보았다. 그 결과 제안된 가산점수제는 기존의 표준점수제가 갖고 있던 여러 가지 문제점들을 크게 완화하거나 해소하는 것으로 나타났다.

In the current College Scholastic Aptitude Test (CSAT), the standardized scoring system is being adopted to adjust te differences of degrees of difficulty between the optional subjects. But it becomes clear that the system has several weak points, some of which are considered to be very serious. In this paper we propose an alternative method, so-called the additive scoring system. It determines the additional points per each subjects, according to the subject mean scores. The proposed method has been simulated using the data of 2005' CSAT, and it turns out that the additive scoring system reduces or remove the troubles caused by the standardized scoring system.

This study examines and presents reasonable improvement measures for the operation and revision of the relative value scoring system, and the basis for performance of a medical technologist. Seven hospitals were enrolled in the study, and included 5 resident laboratory medicine specialists and 53 medical technologists, giving a ratio of 10.6 technologists per laboratory medicine specialist. The average of professional manpower scores was 18, and the average of each medical institution's total score was 78. Ratings and additional rates were in the range 2~3%, and quality-added ratios were 2~3%, with no significance. Excluding pathological testing and assessing physiological functions, the average number of diagnostic tests for health insurance claims were 9,618,062, including 4,378,146 points for 5% of the total relative value scores. According to the DEA, the appropriate number of medical technologist is one person per 49,974 points of relative value. In conclusion, our study results indicate that it would be desirable to set the appropriate workforce for medical technologist to one person per 50,000 points of relative value. Our data could be used as a basis for enhancing productivity of the workforce and balancing health care resources.

Although the evaluation system for excavation reports has been in operation for over 10 years, there has been no research on the evaluation system. First, this study examined the changes of the evaluation system, and secondly, it analyzed the evaluation factors affecting the evaluation results. As a result of institutional analysis, the present evaluation result is being utilized in PQ, and it is suggested that the evaluation subject institution is limited to the excavation institution, which may cause disadvantages to the participating museums. We also pointed out that a small number of jury members are currently evaluating the report and therefore need to reinforce it to ease the burden of assessment. As a result of evaluation factor analysis, it was confirmed that the target score was lower but the actual effect score was higher. In addition, it suggested that the indicators should be improved because the report system, headings, natural archaeological environment, scope and method of survey, and editing and printing indicators are less influential than other indicators. In addition, we conducted a regression analysis of each group by examining the appropriateness of classification amounts according to current excavation costs. As a result of the analysis, the cost of excavation in the second and third groups in 2015 and 2016 was found to affect the score. This emphasized the need for an in-depth approach to estimating the taxonomic value of the group, which is inconsistent with the initial objective of not affecting the assessment results according to excavation costs.
