  • 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.

  • This study aims to analyze the impacts of the QS Asia University Rankings (QSAUR) indicators and to compare the scores obtained by major countries. Hierarchical multiple regression was performed on the results of the QSAUR 2013-2015 and the average indicator and overall scores of each country were calculated. In the QSAUR, the most influential indicator was academic reputation. Each indicator's influence corresponded to its assigned weights and standard deviations. The results of the comparison revealed that Japan, South Korea, and China had the largest number of institutions among the top 150, while Singapore maintained the highest average scores on the indicators as well as the overall score. Each country had different areas that required improvement. South Korean colleges scored lower than some countries on academic reputation, papers per faculty, and international faculty. To attain higher ranks in the QSAUR, academic reputation, institutions' research capability improvement, and internationalization are needed. The implementation of these strategies is necessary to diminish the gap between South Korean institutions and other Asian institutions.

  • 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.

  • This paper introduces a new bibliometric measure called Quality Factor, which assesses multiple facets of faculty research performance. The computation of Quality factor is based on a combination of publication count, citation count, h-index, and Impact Factor. In order to analyze the relationship between Quality Factor and other bibliometric measures (publication count, citation count, h-index, g-index, Impact Factor), the study collected publication data of 189 Korean Library and Information Science professors from 2001 to 2014 to produce the rankings of the faculty by each bibliometric measure and computed Spearman's rank correlations between the rankings. The overall results showed Quality Factor to be correlated to citation-driven measures (citation count, h-index, g-index), but the scatterplot as well as rank-interval analysis showed Quality Factor to be distinctive and more discriminating than other measures.

  • 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.

  • Within a basin, there are potentially multiple locations that can be used as a washland, given their relatively small size when compared with other hydraulic facilities such a dam. However, it is unreasonable to install washlands in all these potential locations due to economic and environmental considerations. In this study, a new methodology for determination of installation priority of washlands is presented. How to integrate the decision variables in this decision making problem has been a key issue in previous studies because a washland can provide many benefits such as flood reduction, agricultural benefit and recreational benefit. In particular, a methodology is needed to integrate all decision variables realistically, properly and reasonably, in situations where there is not sufficient data for direct integration of all these decision variables such as construction cost or benefits a washland can provide. This new methodology aims to suggest how to integrate methodologies used in previous studies. The suggested methodology uses four different rankings which are determined based on a flood reduction effect, a relative significance index, an economic analysis, and a space planning suitability index. These rankings are integrated to determine a final installation priority ranking of washlands by a multi-dimensional scaling method. The new methodology has been applied to the Anseong river basin, to show its applicability, and the application result compared with those of previous studies.
