Purpose: To develop and test the validity and reliability of the Korean version of the Family Management Measure (Korean FaMM) to assess applicability for families with children having chronic illnesses. Methods: The Korean FaMM was articulated through forward-backward translation methods. Internal consistency reliability, construct and criterion validity were calculated using PASW WIN (19.0) and AMOS (20.0). Survey data were collected from 341 mothers of children suffering from chronic disease enrolled in a university hospital in Seoul, South Korea. Results: The Korean version of FaMM showed reliable internal consistency with Cronbach's alpha for the total scale of .69-.91. Factor loadings of the 53 items on the six sub-scales ranged from 0.28-0.84. The model of six subscales for the Korean FaMM was validated by expiratory and confirmatory factor analysis (${\chi}^2$ <.001, RMR<.05, GFI, AGFI, NFI, NNFI>.08). Criterion validity compared to the Parental Stress Index (PSI) showed significant correlation. Conclusion: The findings of this study demonstrate that the Korean FaMM showed satisfactory construct and criterion validity and reliability. It is useful to measure Korean family's management style with their children who have a chronic illness.

F-Measure is one of the external measures for evaluating the validity of clustering results. Though it has clear advantages over other widely used external measures such as Purity and Entropy, F-Measure has inherently been less sensitive than other validity measures. This insensitivity owes to the definition of F-Measure that counts only most influential portions. In this research, we present $F_n$-Measure, an external cluster evaluation measure based on F-Measure. $F_n$-Measure is so sensitive that it can detect their difference in the cases that F-Measure cannot detect the difference in clustering results. We compare $F_n$-Measure to F-Measure for a few clustering results and show which measure draws better result based upon homogeneity and completeness.

The purpose of this paper is to examine what is meant by a ralid measure of health. Guyatt, Kirshner and Jaeschke propose that health tests should be designed so as to have one of several kinds of validity: 'longitudinal construct validity' for those which are used for longitudinal research designs, and 'cross-sectional construct validity' for those which are used for cross-sectional designs. Williams and Naylor argue that this approach to test classification and validation confuses what a test purports to measure with the purpose for which it is used, and that some tests have multiple uses. A review of the meanings of validity in the psychologica test literature shows that both sets of authors use the term validity in an idiosyncratic way. Although the use of a test (evaluated by content validity) should not be conflated with whether the test actually measures a specified construct (evaluated by construct validity);' if health is actually made up of several constructs (as suggested in Hyland's interactional model) then there may be an association between types of construct and types of purpose. Evidence is reviewed that people make several, independent judgements about their health: cognitive perceptions of health problems are likely to be more sensitive to change in a longitudinal research design. whereas emotional evaluations of health provide less bias in cross-sectional designs. Thus. a classification of health measures in terms of the purpose of the test may parallel a classification in terms of what tests purport to measure.

This study was performed to verify the validity and utility of the Korean Behavior Rating Inventory of Executive Function-Preschool Version(BRIEF-P). The BRIEF-P is one of the most used instruments to measure Executive Function(EF) and a teacher-rating assessment method designed to measure the executive function of preschoolers(age 2-5). A total of 200 preschoolers(104 boys, 96 girls; recruited aged 3 to 5years) participated. Confirmatory factor analysis was carried out to evaluate the model structure. Correlation analysis was done to verify the concurrent validity. In the results, the model fit indexes were good with the five BRIEF-P subscales (that is, inhibit, shift, emotional control, working memory, plan/organize). The internal consistency of the BRIEF-P five subscales were supported. As a results, the Korean Behavior Rating Inventory of Executive Function-Preschool Version(BRIEF-P) was confirmed to be a reliable and valid assessment tool to measure executive function in preschoolers.

The scores of TOEFL, TOEIC and TEPS have been increasingly used for many purposes in Korea In particular, these test scores are being used as a measure of the test-takers' overall communicative competence. Nonetheless, few studies have been conducted that investigate the validity of the test scores used for this purpose. As a preliminary step to explore the validity of the test scores, we conducted a small scale study by comparing 30 university students' scores in TOEFL, TOElC and TEPS with their class performances in English conversation and composition courses. The correlations between the test scores and the grade point averages of the courses show that the test scores are much harder to use as a valid measure of test-takers' overall communicative competence than usually thought to be and that the score in TOEFL is, nonetheless, a more reliable measure than the ones in the other tests. Although tins study has a few limitations such as the small number of participants, the homogeneity of the sample as a group, etc, it provides some insight into the use of the three tests for measurement of overall communicative proficiency and suggests need for conducting further validation studies in these areas.

Background: Knee osteoarthritis (OA) is a single most arthritic disease. Knee joint space width (JSW) is commonly used for grading severity of knee OA. However, previous studies did not established criterion validity and test-retest reliability of ultrasound (US) image for measuring JSW. Objects: The aim of this study was to establish criterion validity and test-retest reliability of US measurement of medial and lateral knee JSW. Methods: Twenty-nine subjects with knee OA were participated. The US and X-ray were used to measure knee JSW. One sample Kolmogorov-Smirnov test was used to confirm the data normal distribution. Pearson correlation coefficient and ICC were used to calculated and establish criterion validity and test-retest reliability, respectively. Results: US measurement of medial and lateral knee JSW was highly correlated with radiographic imaging measure (r=.714 and .704, respectively). Test-retest reliabilities of medial and lateral knee JSW were excellent correlated (ICC=.959 for medial side and .988 for lateral side, respectively). Conclusion: US may be valid tool to measure knee JSW.

Purpose: The study was designed to develop an instrument to measure risk factor-related deviant behavior (RFRDB) for the elderly. Methods: The preliminary instrument including 52 items to measure the risk factor-related deviant behavior for the elderly was developed through conceptual framework based literature review. The items were reviewed by experts to reveal the Content Validity Index (CVI). Then, construct validity and reliability were tested using factor analysis, comparative groups, and Cronbach's alpha with data from 233 elderly. Results: Among 52 items, 27 questions in the RFRDB instrument were selected from content validity and 21 questions in the final RFRDB were developed from testing validity and reliability. Results of empirical analysis(retest) of RFRDB were supported by 70% congruity with conceptual framework through literature review. The RFRDB has been completed by validity testing by known-group technique. The final developed RFRDB of the elderly has 21 questions each with a 4-point Likert Scale. Conclusion: The RFRDB may be utilized as a measurement to assess the risk of elderly deviant behavior.

퍼지 클러스트링은 전통적인 FCM을 이용하여 수행될 수 있다 그러나 FCM을 사용하는데 있어서 고려해야 할 문제점은 크게 두가지이다. 첫째는 FCM은 초기 멤버쉽 함수의 지정에 민감하고, 둘째는 FCM 알고리듬의 수행에는 클러스터의 개수를 미리 지정 해 주어야 한다는 것이다. 따라서 FCM과 동시에 수행하여야 할 과제는 클러스터의 개수를 찾기 위하여 타당성 척도를 이용한 시뮬레이션을 수행하여야 한다. 본 논문에서는 위의 두 가지 문제점을 동시에 해결 할 수 있는 FCM 알고리듬을 제시하고, 그 적용성을 시뮬레이션을 통하여 검증한다. 본 논문의 기여도는 MV-FCM 알고리듬의 제시와 이 알고리듬의 타당성 척도로써의 효율성이다.

This study is an analysis on the focus of textbooks regarding the statistical chapters of "measures of representative(central tendency) and of the spread". Applying the summary-concept criteria of Juhyeon Nam(2007), 4 kinds of aspect of the chapter; (1) definition and its teleological validity of the measures of representative, (2) definition and practical value of the measures of spread (3) distributional form on the measures of representative and of spread (4) location and scale preservation or invariance of the measures of representative and of spread were observed. On the measures of representative, some definitions were insufficient to check the teleological validity of the measure. Most definitions of the measure of spread were based on the practical view points but no preparation for the future statistical inferences were found even by implication. Some books mention about the measures of representative and of spread for distributions, but we could not find any comments on the correspondence between the sample mean and the expectation of a distribution or population mean. However it is stimulant that some books check the validity of corresponding measures with the location and scale preservation or invariant property, that were not found in the previous curriculum.
