  • University ranking models, though they consider multiple indicators to evaluate universities, determine the overall score of each university based on their own normalization and aggregation methods. Thus, the rankings provided by such models primarily depend on actual scores of evaluation indicators, but they are also significantly affected by the normalization and aggregation methods. We examine the normalization methods of four university ranking models used in South Korea, China, and United Kingdom. We discuss a possible unintended consequence of these methods, i.e., some universities who want to improve their rankings may focus on unnecessary indicators, contrary to the evaluator's intension, due to the normalization methods. We suggest a new normalization method based on the statistical characteristics of the distribution of each evaluation indicator so that the new method can motivate the universities to move into the desirable directions intended by the evaluator.

  • Statistical reliability in the sensory evaluation measures the agreement of judgements for several observers. Kendall's coefficient of concordance for multiple rankings. and coefficient of consistence and coefficient of agreement for paired comparisons are frequently used as the standard reliability measures. The main idea and the computational formula of these coefficients in various situations are explained in detail with some real (cloth designing) examples. Moreover a user-friendly computer program called as MultPair is introduced. We expect that this expository paper and the computer program give a practical help to the researchers who use the sensory evaluation techniques.

  • 본 논문은 QS의 아시아대학 순위 평가가 활용하고 있는 평가지표들의 총점에 대한 영향력을 분석하고, 주요 아시아권 국가들의 평가결과를 비교하는 것을 연구목적으로 하였다. 이를 위해 QS 아시아대학 순위 평가의 2013~2015년도 결과를 이용하여 계층적 중회귀분석을 실시하였으며, 각 아시아권 국가들의 대학들이 획득한 평가지표와 총점의 평균을 계산하여 비교하였다. 분석 결과, QS 아시아대학 순위 평가에서 가장 영향력이 있었던 평가지표는 학계 평가였으며 평가지표들의 영향력 순서는 배정받은 가중치와 평가지표들의 표준편차 순서와 유사하였다. 국가별 비교 결과, 일본, 한국, 중국 등이 가장 많은 대학들을 상위권에 진입시켰고, 평균 점수가 가장 높은 국가는 싱가포르였다. 국가별로는 개선을 위해 집중해야 할 분야가 상이하였다. 국내 대학들이 취약한 영역은 학계평가, 교원당 논문 수, 외국인 교원 비율이었다. QS 아시아대학 순위 평가에서 상위권에 위치하기 위해서는 학계 평가를 개선시키기 위한 전략이 필요하다. 그리고 자국 내 대학들의 연구력을 향상시키고, 국제교류를 활성화시킬 수 있는 정책을 도입하는 것이 필요하다. 국내에서도 이러한 전략과 함께 대학 간 격차를 줄이는 것이 중요하다.

  • Purpose: The purpose of this study was to describe the current status of utilization and costs of home health nursing care by the levels of medical institutes in Korea. Method: A secondary analysis of existing data was used from the national electronic data information(EDI) of 148 home health agencies for 6 months from May to Oct 2005 in total. Result: The 148 agencies had multiple services in cerebral infaction, essential hypertension, sequoia of cerebrovascular disease, type 2 diabetes mellitus, etc.. The highest 10 rankings of 76 categories of home health nursing services were composed of 96.4% of the total services, such as simple treatment, inflammatory treatment, urethra & bladder irrigation, inserting indwelling catheter etc., in that order. The highest 20 rankings of 226 categories of home examination services were composed of 77.0% of the total home examination services. In addition, the average cost of home health care per visit was 46,088 Won (${\fallingdotseq}$ 48 $, 1 $=960 Won). The costs ranged from 74,523 Won (${\fallingdotseq}$78 $, loss of chronic kidney function, N18) to 32,270 Won (${\fallingdotseq}$34 $, other cerebrovascular diseases, 167). Conclusion: Results suggest that client characteristics of hospital based HHNC are not different from community based HHNC or visiting nursing services for elderly. The national results will contribute to baseline data used to establish a policy for the home health nursing care system and education.

  • 본 연구는 교수의 연구업적을 보다 다면적으로 측정하기 위한 합리적 방법을 고안하기 위하여 새로운 논문계량지표인 Quality Factor를 개발하였다. Quality Factor는 총 논문수, 피인용수, h-index, Impact Factor를 이용하여 수치를 도출한다. 새로 개발한 지표인 Quality Factor와 다양한 지표(논문 수, Impact Factor, 피인용수, h-index, g-index)간의 관계를 분석하기 위하여, 본 연구는 국내 문헌정보학과 교수 189명의 14년간(2001-2014)의 학술논문데이터를 바탕으로 그들의 지표별(논문 수, Impact Factor, 피인용수) 순위를 산출하고 지표들 간에 스피어만 순위상관관계를 도출하였다. 그 결과, Quality Factor는 전체적으로 피인용 수의 영향을 주로 받는 지표(피인용수, h-index, g-index)와 유사한 상관관계를 보였으나, 산점도에서 Quality Factor가 타 지표에 비하여 분산된 분포를 나타내면서 개별식별성이 높은 것으로 드러났으며 군집 분할 분석에서도 타 지표들과 상이한 상관관계를 보여주었다.

  • To provide the information necessary for the insurance medicine management plan, price discount rates among the insurance medicines were studied. A total of 2,107 items of insurance medicine of which prices were discounted via governmental inspections of real transactional process of insurance medicine were analysed. The conclusions are as follows; 1. Among the variables relevant to the characteristics of manufacturers, price discount rates of insurance medicines were statistically significant with production rankings of manufacturers, incorporation year, existence of investments by foreign corporation, existence of a research institute, and enrollment in the exchange. And among the variables relevant to the properties of medicines, the number of enrolled items which have the same components, classification, the date of new enrollment, the sales of items, and the number of raw materials in the items were statistically significant. 2. Stepwise multiple regression was done to identify the factors which affect the price discount rates of insurance medicines. The number of enrolled items which have the same components, production rankings of manufactures, classification number (medicines for function of tissue cells), incorporation year(1940-1949), existence of investments by foreign corporations, classification number (anti-germ medicines), number of raw materials In the items, the sales of items, and medicines whose major objective is not treatment were significant variables and the $R^2$-value for these variables was 21.2%. Considering all of the above results, for management of insurance medicines, it seems important that the real transactional prices of insurance medicines should be identified systematically, focusing on the properties which affect the price discount rates of insurance medicines.

  • The present research studied the relationship between children's social competence and popularity and examined popularity variables for the prediction of children's social competence. The subjects of this study were 80 children, 40 boys and 40 girls at age 5. Children's social competence was measured by the children's teachers with the use of the Social Competence Scale (Kohn & Rossman, 1972). Children's popularity and unpopularity were obtained from the subjects with the use of Moore's (1973) Sociometric Status Test. Teacher's estimate of the popularity of children was obtained with the use of Connolly & Doyle's (1981) Teacher Rankings of Popularity. The analysis of the data was by Pearson's Correlation Coefficient, and Stepwise Multiple Regression. There were significant relationships between children's social competence and popularity (children's popularity, children's unpopularity, teacher's popularity). Teacher's estimate of child's popularity was the best variable with which to predict children's social competence, the second best variable was children's popularity as measured by Moore's Sociometric Test.

  • PURPOSE. The purpose of this study was to evaluate and compare the translucency of shaded zirconia allceramic systems. MATERIALS AND METHODS. Translucency of 3 different zirconia all-ceramic systems colored by different techniques was compared with a lithium disilicate glass-ceramic (IPS e.max Press). Square-shaped specimens with 0.5 mm thickness were fabricated from In-Ceram YZ, ICE Zirkon and Katana systems in A1, A2 and A3.5 shades according to Vitapan Classical shade tab (n=11). Specimens were then veneered and glazed with corresponding veneer ceramic recommended by each zirconia system manufacturer and the total thickness was set to 1.5 mm. Translucency measurements were performed with VITA Easyshade Compact spectrophotometer after each stage and translucency parameter was calculated. Data were statistically analyzed with repeated measures ANOVA and Tukey multiple comparison test. RESULTS. The control group was significantly more translucent than the zirconia systems (P<.05). ICE Zirkon cores showed the least translucency; neither In-Ceram YZ nor Katana systems were superior to each other in terms of translucency. Translucency of all specimens was decreased after veneering, and the translucency rankings were changed. CONCLUSION. Coloring technique did not have a significant effect on translucency of zirconia cores. Although zirconia systems were less translucent than lithium disilicate glass ceramic, they had partial translucency and there were translucency differences among the zirconia systems. Chroma affected the translucency of precolored zirconia cores.
