  • The estimation problem of predictive value of a positive test(PVP), which is assessing the accuracy of a screening test is considered. Score methods discussed by Gart and Nam(1988) are proposed for constructing confidence interval for PVP. The simulation studies are conducted in evaluating the proposed methods and existing approximate ones.

  • We consider the problem of testing for outliers in generalized linear model. We proceed by first specifying a mean shift outlier model, assuming the suspect set of ourliers is known. Given this model, we discuss standard approaches to obtaining score test for outliers as an alternative to the likelihood ratio test.

  • The purpose of this study was investigated the effects of education for nursing concept to the nursing students who are not attended to major course of nursing education in nursing college. it is hoped that this education for nursing concept will be contribute to positive nursing conceptualization for nursing students. The data for this study obtained from 118 students in attending college of nursing Ewha womens University(1st year; 62, End year; 56). 1st year students(experimental group) was attended to the education for nursing concept by investigators and 2nd year students(control .group) did not. After then tested to two group: Pre and post test for experimental group and post test only to control group. The results obtained were as follows: 1) In experimental group, pre-test mean score was 116.19(SD 50.46) and post-test mean score was 253.02 (SD 66.56). Therefore post-test mean score was higher than pre-test mean score (p=0.0001). 2) There were different score between the experimental group and control group. Control group was higher(207.58, SD 52.42) than experimental group(116.19, SD 50.46) at the pre-test (p=0.0002), but experimental group(253.02, SD 66.56) was higher than control group. (207 58, SD 52.42) at post-test(p=0.0001). These results implied that early intensive education for nursing concept might have positive effects on nursing conceptualization for nursing students.

  • This study was designed to test effects of nursing ethics education (NEE) on moral reasoning and ethical decision making of subjects. This NEE that was teached for 10 hours course was composed of these : Nurses' ethical code, moral responsibility, Moral value and professional accountability, Respect for human life, General ethics, Theory and Norms of biomedical ethics, Ethical decision making model and Discussion about hypothetical ethical dilemmas Twenty-five senior student nurses were sampled from four year college of nursing from Nov. 3rd, 1993 to Nov. 24th, 1993. Data were collected through self-reported questionnaires included two kinds of tests. Rest's Defining Issues Test was adopted to measure the stage of moral development, which was classified with the stage 2 (instrumental relativist orientation), the stage 3 (interpersonal concordance), the stage 4 (law and order), the stage 5A (societal consensus), and the stage 5B (intuitional humanism), the stage 6 (universal ethical practice). In particular, the level of principled thinking (P) was measured by summing these scores of the stages 5A, 5B, and 6. The possible range of P is 0 to 95. As for measuring the levels of morality and nursing dilemma, Crisham's Nursing Dilemma Test was adopted. This test generated the morality score(MS) and the dilemma score (DS). The data were analyzed by t-test, ANOVA, Kruskal-Wallis test, Mc Nemar's test and Pearson correlation coefficients. The results were as follows ; 1. For the Moral Reasoning both before and after NEE, The Mean score of the stage 5A was significantly higher than that of other stages.(P=0.0001) Before NEE, the mean score of the stage 4 was significantly different from stage 2, 3, 5A, and after NEE, different from stage 2, 5B,6. 2. The analysis of change of moral development level revealed that the score of stage 4 increased after NEE.(P=0.0004) 3. The Effect of NEE for the mean score of 5A, 6, P after education was significantly different by birth place. 4. With regard to the five dilemmas postulated such as forcing medication performing cardiac pulmonary resuscitation, reporting a medication error, informing diagnosis to terminally ill adult, and providing new-nurse orientation, the mean score of the MS and the DS was no significant difference with general characteristics of the students. Effect of NEE morality score and dilemma score after education was no significant difference. 5. As for the correlations between moral reasoning and decision making, the score of the stage 2, 5A, 6, DS was positively correlated with the scores of before and after. Positive correlation was also observed between the scores of stage 2 and stage 4, stage 3 and 6. On the other hand, the score of P was negatively correlated with the scores of stage 2 and of stage 4 and of stage 5A. The score of the stage 5A was also negatively correlated with the score of the sge 6.

  • Data from repeated measurements are accomplished through repeatedly processing the same subject under different conditions and different points of view. The power of testing enhances the choice of pertinent analysis methods that agrees with the characteristics of data concerned and the situation involved. Along with the clinical example, this paper compares the analysis of the variance on ex-post tests, gain score analysis, analysis by mixed design and analysis of covariance employable for repeating measure. Comparing the analysis of variance on ex post test, and gain score analysis on correlations, leads to the fact that the latter enhances the power of the test and diminishes the variance of error terms. The concluded probability, identified that the gain score analysis and the mixed design on interaction between "between subjects factor" and "within subjects factor", are identical. The analysis of covariance, demonstrated better power of the test and smaller error terms than the gain score analysis. Research on four analysis method found that the analysis of covariance is the most appropriate in clinical data than two repeated test with high correlation and ex ante affects ex post.

  • The purpose of this study was to examine the effects of sensory stimulation type on the learning of the elderly. The study implemented elderly verbal learning test by evenly dividing a total of 40 elderly people into auditory stimulation followed by visual stimulation group(AVG), visual stimulation followed by auditory stimulation group(VAG), simultaneous visual and auditory stimulation group(SG), and auditory stimulation group(AG). The result are as follows. SSG showed highest results in most of the test, followed by AVG, VAG, and AG. In particular, SG showed a statistically significant difference in immediate recall total score and short delay free recall score(p<.05). In the post-hoc test results of immediate recall total score, SG showed highest score with a statistical significance. AVG showed the second highest score, followed by VAG and AG and all showed a statistic significance(p<.05).In the post-hoc test results of short delay free recall score, SG and AVG showed a statistically significantly higher score than AG(p<.05). The results suggest that simultaneous stimulation of visual and auditory sense is more effective for improving the learning of the elderly people than visual stimulation followed by auditory stimulation or auditory stimulation followed by visual stimulation.

  • Count data are often overdispersed, and an appropriate test for the existence of the overdispersion is necessary. In this paper we derive a score test based on the extended quasi-likelihood and the pseudolikelihood after adjusting to the Bartlett factor. Also, we compare it with Levene (1960)'s F-type test suggested by Ganio and Schafer (1992).

  • A new En score of the proficiency test (PT) is formulated; it is applicable when a correlation exists between the reference and participant's values. Based on the uncertainty propagation rule given in ISO/IEC Guide 98-3 (GUM:1995), the En score covering the correlation case is newly developed for the PT. The new En score will be applied in a future PT organized by the Korea Research Institute of Standards and Science (KRISS) dosimetry team. The new En score will enhance measurement traceability and contribute to improving the quality management system of participants in the KRISS PT by avoiding performance underestimation.

  • The present research investigated the validity and reliability of the Verbal and Figural tests of the Torrance Tests of Creative Thinking(TTCT). Its potential as a basis of normative data, and differences in children's sex and grade in school were also examined. The subjects of this study were 360 children (180 boys, 180 girls) enrolled in two public elementary schools grades 1-6. Pearson's product-moment coefficient and two-way analysis of variance were used for analyzing data collected from these tests. The present research showed a coefficient of concurrent validity of the TTCT-Verbal test of .40. The coefficient of equivalence from reliability between the TTCT-Verbal test and TTCT-Figural test was .65 (p<.01). Regarding the coefficient of interscorer reliability, the total score of the TTCT-Verbal test was .86 and that of the TTCT-Figural test was .95. The coefficient of intrascorer reliability on the total score of the TTCT-Verbal test was .93 and that of the TTCT-Figural test was .96. Generally, score reliability was .86 to .96 in total score but there were great differences in the reliability of sub-factor scores. There were no significant differences between boys and girls in the distribution of scores on the TTCT-Verbal test and the TTCT-Figural test. There were significant differences between grades (p<.01) on the distribution of total scores and subfactor scores of the TTCT-Verbal Test.
