Background: The aim of the study was to test the validity and reliability of the Perceived Future Decent Work Securement Scale for Turkish nursing students. Methods: A cross-sectional, methodological study design was used. The study was carried out at three nursing undergraduate programs in Turkey during the academic year of 2020-2021 with 336 senior nursing students. Language validity and content validity analyses were performed for the scale adaptation, followed by confirmatory factor analysis (CFA) for construct validity. The reliability of the scale was determined using the test-retest and Cronbach's alpha internal consistency coefficient. Results: The scale-content validity index score was 0.988. In CFA, all goodness-of-fit indices verified the acceptable fit of the model; its root mean square error of approximation was 0.076; the normed fit index was 0.909; the standardized mean square residual was 0.097; the relative fit index was 0.881; the goodness-of-fit index was 0.915; the adjusted goodness-of-fit index was 0.872 and χ²/df = 2.932. The overall reliability was α = 0.86. The item-total correlations of the scale were above the acceptable level, and the test-retest analysis had a high correlation. The access to healthcare (14.68, SD 3.53) obtained the highest average score, and the adequate compensation (8.52, SD 3.76) was the lowest rated by the senior nursing students. Conclusion: The Perceived Future Decent Work Securement Scale is a valid and reliable scale to assess nursing students' future decent work securement.

Objectives : Dementia has emerged as a leading public health problem in elderly persons, and its early detection is important for the treatment of curable cases, and in the educational support for other family members. Although dementia screening tests are available, they have not gained widespread use in community or primary care settings. Our goal was to validate the Tine and Change (T&C) Test, -including its validity and reliability in patients, and to assess it as a simple, standardized method for the screening of dementia in the rural elderly. Methods : The participants in this study comprised of 59 patients from an urban hospital and 405 persons from a rural community aged 65 years or older. The time test evaluated the understanding of clock hands indicating 11:10, and the change test the ability to make 1,000 Won from a group of coins, consisting of one 500, seven 100, and seven 50 Won coins. The T&C ratings were validated against a reference standard based on the physician's diagnosis of the patients. The convergent validity in relation to other cognitive measure, test-retest agreement, and inter-observer reliability were assessed. To assess the relationship between the Korean Mini-Mental State Exam (K-MMSE) and the T&C Test, the mean K-MMSE scores were compared with the results of the T&C Test in the elderly from a rural community. Results The T&C Test had a sensitivity and specificity of 73.0, and 90.9%, and positive and negative predictive values of 93.1, and 66.7%, respectively. The test-retest and inter-observer agreement rates were both 95%. The K-MMSE scores and T&C Test were significantly related in the elderly from a rural community (p<0.01), The T&C Test was not influenced by the educational status. The Time and Change Tests took a mean of 6.3 and 12.7 seconds, respectively, to complete Conclusion : The T&C Test is a simple, accurate and reliable, performance-based tool in the screening for dementia. Because it is quick, and easy-to-use, it is hoped the T&C Test will be used for the widespread cognitive screening of aging populations.

For test-retest reliability, it is important to consider whether the attributes of the construct being measured is temporally stable or not. For responsiveness, it needs a longitudinal study design including a treatment/intervention known to induce a change on the construct to be measured.

This study was conducted in order to develop an aptitude test for child care teachers (ATCCT) and to analyze it in terms of both validity and reliability. The main participants in this study consisted of 710 pre-service child care teachers. The results of factor analysis identified 7 factors and 56 items which were selected from 121 items in the original scale. The seven factors were as follows; interpersonal relationship management abilities, receptiveness and responsiveness to children, creativity and personal development, the ability to form close relationships with children, the ability to supervise child safety, the sense of duty, and positive emotions. The four factors were related to social relationship. Criterion-related validity was established by using correlations between the ATCCT and the TSES (Teacher Self-efficacy Scale). The internal consistency was found to be relatively high (Cronbach's ${\alpha}$ = .94) and test-retest reliability was also established (r = .53). In addition, there were differences among pre-service child care teacher groups according to both relative levels of education and courses taught.

This paper considers a strategy for planning of rework in semiconductor monitoring burn-in test process. The equipment error in monitoring burn-in test process generates many defects. These defects are transformed into good products by rework process, i.e. retest. Rework has the advantage of saving production costs. But rework increases holding costs and incurs rework costs. In monitoring burn-in test process, rework depends on operator's experience with no pre-defined specification. In practice, a number of rework activities are performed with respect to the product importance and inventory quantity. Moreover, disregard for order jobs schedule have caused due date penalties. So a strategy for planning of rework by which order jobs schedule are not affected is suggested. Futhermore, production costs, rework costs and inventory costs for planning of rework are considered.

목적 : 본 연구의 목적은 종합 신경인지기능 평가인 Comprehensive Neurocognitive Function Test(CNFT)의 표준화 자료를 얻고 신뢰도와 공인타당도를 검증하기 위함이다. 연구방법 : CNFT는 기억력, 집중력, 감각,운동협응, 전두엽 및 고위인지기능을 평가하는 것으로 결과는 전산화되어 일관성 있고 자동으로 처리된다. 연구대상은 표준화 자료를 얻고 신뢰도를 검증하기 위한 조사에서 20대부터 80대 이상까지 서울특별시와 대구시에 거주하는 정상 성인 140명이 참여하였다. Computerized Neurocognitive Function Test(CNT)와의 상관관계를 통하여 타당도를 검증하기 위한 조사에는 정상 성인 40명이 참여하였다. 결과 : 정확도는 연령이 증가할수록 낮아지며, 반응속도는 늦어졌다. 또한 영역별 점수 분석결과 기억력, 전두엽 및 고위인지기능 점수가 낮은 편으로 나타났다. 2주 간격의 검사-재검사 신뢰도는 r=.48~.85로 나타났고 두 검사 사이의 유의한 차이는 없었다(p>.05). CNT와의 세부 영역과의 상관계수는 r=.67~.79이다(p<.05). 결론 : 종합 신경인지기능 평가인 CNFT의 표준자료와 해석기준이 마련되었다. CNFT는 인지기능에 문제를 평가할 수 있는 신뢰도와 타당도를 갖춘 평가도구이다.

최근 3D 디스플레이 환경들이 확대되면서 컴퓨터와 3D 디스플레이 장치들을 통해 개인의 입체 시력을 검사하려는 다양한 시도들이 제안되었다. 기존의 입체검사도구들에 비해 3D 디스플레이를 이용한 입체 시력 검사는 여러 장점들을 갖고 있지만, 3D TV나 모니터에서는 최소로 조작할 수 있는 양안시차의 한계가 1픽셀이다. 관찰거리가 짧은 pc 환경에서는 1 픽셀의 양안 시차 값은 정상 입체 시력을 구분해 낼 수 있는 기준보다 너무 크다. 본 연구에서는 이러한 문제를 극복하고자 가보 자극을 사용하여 1픽셀보다 작은 단위의 양안 시차를 제공할 수 있는 입체 검사 자극을 생성한 후 이 자극이 입체 시력 검사자극으로 적용가능한 지를 탐색적으로 살펴보았다. 넓은 범위의 시차를 1회만 측정하는 기존의 입체 시력 검사 대신에 좁은 범위의 시차 값에 대해 조건 당 10번의 반복 측정을 실시하여 각 개인별 정답률을 구하였다. 가보 영상을 사용한 검사결과의 신뢰도와 타당도를 살펴보기 위해 기존 입체 시력 검사에 사용되는 무선점 입체 자극을 이용한 검사 결과와 가보 영상을 이용한 검사결과를 비교하였고 그 결과 온건한 정도의 상관관계를 보여주었다. 또한 검사 결과가 얼마나 신뢰도운지를 평가하기 위해 약 1개월 후에 동일한 환경에서 가보 영상을 이용하여 입체 시력을 측정한 후, 두 검사 결과를 비교한 결과 높은 검사-재검사 신뢰도를 보였다. 이러한 결과는 가보 자극을 사용하여 입체 검사 도구를 개발하는 경우 충분히 신뢰로운 결과를 산출할 수 있음을 시사하는 것으로, 가보 자극은 충분한 관찰거리가 제공되지 않거나 혹은 매우 정밀한 단위로 입체 시력을 평가할 필요가 있는 상황에서 개인의 입체 시력을 평가하기에 적절한 자극임을 보여준다.

This study aimed to examine the reliability and validity of a diagnostic instrument to be used to measure the developmental level of very young children (aged birth through 36 months) and to screen young children at risk. The subjects of this study were 861 young children. Data were analyzed by item response distribution, item discrimination, reliability, and validity of the scale. Items reflected the developmental level of each age group. Overall internal consistency was relatively high (Cronbach's ${\alpha}=.90{\sim}.95$), and test-retest (after 2 weeks) reliability was high. Content validity was examined by a panel of experts in the related field. The construct validity as well as the concurrent validity of this instrument was also established.
