Objects : This study was carried out to develop the Korean form of Leyton Obsessional Inventory-Child Version(LOI-CV) designed to assess the obsessive compulsive symptoms in children and adolescents. The LOI-CV was modified into a paper-and-pencil form in order to administer it to group. Methods : We applied the Korean form LOI-CV to 127 elementary, middle and high school children, and retest it to 82 children with 3 weeks interval. Together with LOI-CV, Korean form of SCL-90-R which had been proved its reliability and validity, were administered to the all subjects for examining of concurrent validity. And then we examined whether this scale discriminates between obsessive patients, psychiatric controls and normal controls in the level of obsessive symptoms. Results : Test-retest reliability, internal consistency were very satisfactory. Concurrent validity with SCL-90-R was moderate level. And obsessive patients was scored significantly higher than psychiatric and normal controls in the level of obsessive symptoms. In factor analysis, items are clustered to 5 factors. In the global obsessive symptom, obsessive scores of female elimentary school students were higher than that of male students. Conclusions : These results indicate that the Korean form of LOI-CV is reliable and valid self-rating scale to assess the obsessive-compulsive symptoms in Korean children and adolescents. Author suggests that future research is needed for Korean version standardization study in normal and clinic-refered population.

The purposes of this study were to assess the reliability of the Korean version of Montreal Cognitive Assessment (MoCA-K) and Korean version of Mini-Mental State Examination (MMSE-K) and correlation between MoCA-K and MMSE-K to detect cognitive impairment following stroke determined by a neuropsychological battery. Fifty-two chronic stroke patients participated in this study. They divided two group, normal cognitive group (20 patients) with stroke and cognitive impairment group with stroke (32 patients), and research period was from October 2th. to November 30th., 2013. The subjects were measured K-MoCA and K-MMSE. Normal cognitive group showed the moderate reliability in K-MoCA and K-MMSE. Cognitive group showed the more moderate relaibility in K-MoCA and K-MMSE. There was positive correlation as the more score of K-MoCA gain, the more score of K-MMSE showed in both group. The results suggest that both clinical measures are moderately sensitive and proper feasibility to chronic post-stroke cognitive impairment. The both clinical tools suggest to use in research and clinical settings by a neuropshchological battery.

This study aims to develop a reliable and valid Geriatric Reaction Inventory-Simplified Form (GRI-SF). Reaction inventory for measuring anger (Evans & Stangelang, 1971) is an assessment tool in a view of stimuli for measuring the level of anger invoked from the anger-triggered experiences. Yet, the inventory, comprised of 76 items, is sometimes incapable of finishing up the lengthy questionnaire. In the sense, a simplified form of RI is necessary for those lacks cognitive ability such as stroke patients or the elderly. In study 1, a full version of Reaction Inventory was given for the elder who are above 60, and ten items out of 76 was selected to form GRI-SF based on the psychometric theory. In study 2, the reliability and validity of GRI-SF was tested by another sample group of elderly with some additional examinations. The reliability was good with Cronbach's alpha of 0.79. Based on the fact that GRI-SF measures the personal trait anger, GRI-SF should not be only strong correlation with the scores of trait anger strongly, but be less correlated with scores representing other aspects of anger. As a result, GRI-SF score showed strong correlations with trait anger among other sub-categories of State-Trait Expression Inventory (STAXI), and was less correlated with anger-out score which reflects behavioral aspect of anger. Moreover, it is less correlated (r=.41) with hostility representing attitudinal or cognitive aspects of anger. Consequently, GRI-SF, constructed by this research, is verified to be a reliable and valid tool for anger measurement.

The development of an integrated technology including fabrication of corrosion defect specimens and their practical use is needed to enhance the reliability of eddy current test for nuclear steam generator tubing. In this paper, the necessity and importance are presented from the viewpoint of the structural integrity, simulation specimens for real defects, and experiences from the destructive examination of pulled tubes. The models for several corrosion defects we also briefly introduced, with the scheme for their practical use.

This study has developed the test tool to measure the level of spatial concept in the astronomy education for high school students. The items of the test tool are composed of basic elements (spatial position, spatial reasoning, spatial variation) forming spatial concepts in the astronomy. The test tool was applied to the 274 high school students. As a result of item analysis, the test tool showed that the content validity was 98%, the reliability (KR 20) was 0.84, the measure the level of astronomical spatial concept for the high school students.

본 연구는 스마트폰 Inclinometer와 수동 고니오미터를 사용하여 대학생 50명을 대상으로 엉덩관절 운동범위를 검사자 6명이 측정하여 검사자간의 신뢰도를 알아보고자 하였다. 측정결과 높음에서 매우 높은 수준의 신뢰도가 보여, 스마트폰 Inclinometer를 이용한 관절 운동범위 측정값은 수동 고니오미터를 대체 할 수 있을 것으로 생각된다.

Purpose: To assess the reproducibility and repeatability for each color vision test method. Methods: The subjects for color vision test were 30 students without congenital color vision deficiency and they major in optometry in a university, Korea. The type of color vision test selected for this study were Hans color vision test, Hans 15 hue test and Lanthony D 15 hue test. The Ishihara test was added for assessment of reliability of inter-tester. Results: All of the subjects were classified into normal at pseudoisochromatic plates, but one subject's result showed mild blue-yellow color deficiency at Hue discrimination. Results of 3 repeated test for subjects and inter-tester examination showed no errors at pseudoisochromatic plates. There were differences in mild errors among repeated test at Hue discrimination, but no differences were found in the results of repeated test to classify color vision deficiency. Conclusion: Each tester had better be more skilled to test even simple color vision test for eliminating the possibility of mild errors. Each subject might just as well be careful in color vision test. It is required to test both method of pseudoisochromatic plates and Hue discrimination in screening test.

The purpose of this study was to investigate the relative influence of multiple error sources and to find optimal measurement conditions that obtain a desired level of reliability of a creative attitude test in mathematical creativity. This study analyzed the scores of the Creative Attitude Scale-Korea allowed to access publicly of 125 general students and 109 mathematically gifted students by performing a multivariate generalizability analysis. The main results were as follows. First, based on reliability, the Creative Attitude Scale-Korea was measured less precisely for mathematically gifted students. On the contrary, based on the conditional standard error of measurement, it was measured less precisely for general students. However, the Creative Attitude Scale-Korea showed strong reliability in both groups. Second, the optimal weights should adjust to .3, .3, .4 in mathematically gifted students and .4, .4, .2 in general students with three scoring components of divergent attitude, problem solving attitude, and convergent attitude based on the maximum reliability. Third, to approach desirable reliability, it is possible to use one component of divergent attitude in general students but three components of divergent attitude, problem solving attitude, and convergent attitude in mathematically gifted students. Finally this study proposed application plans for the Creative Attitude Scale-Korea and future directions of research.

공장 내에서 부적절한 배선 및 설치 등에 의하여 검사과정을 수행할 경우 noise나 오결선을 유발시키며, 이는 측정해야할 신호가 부적절한 동작을 발생시키거나 검사가 되어 출하 후에 하지 않아도 될 A/S 지원을 해야 하는 등의 추가 경비가 소요되는 문제까지도 야기시킬 수 있다. 이때, 사용자측에서 발생될 불만에 따른 회사 및 제품의 신뢰도 저하는 더 큰 문제가 아닐 수 없다. 본 개발에서는 GUI(Graphic User Interface) 환경과 통신기술을 접목하여 다양한 제품의 검사를 위한 시스템을 개발하고자 한다.
