Objective : This study aims to verify the content validity and inter-rater reliability of the Korean version of the Peabody Developmental Motor Scale 2 (PDMS-2) and to identify the concurrent validity by comparing it with the Korean version of the Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2). Methods : PDMS-2 was translated by the researcher and an eighth-year clinical occupational therapist. The content consistency of the Korean version of the PDMS-2 was verified by three professors with experience using it. After the verification of the content consistency of the PDMS-2 by the five clinical occupational therapists and the additional revision, the Korean version of the PDMS-2 was completed. The researcher and another occupational therapist evaluated the Korean version of PDMS-2 in 50 children and measured the inter-rater reliability. Concurrent validity was measured by comparing the results of the Korean version of PDMS-2 and Korean version of BOT-2. Results : The content consistency test showed overall agreement of mean 3.45, and the content understanding test showed a high level of understanding of mean 3.69. The inter-rater reliability and concurrent validity of the Korean version of the PDMS-2 showed a statistically significant correlation. Conclusion : The Korean version of the PDMS-2 showed high content understanding, reliability, and validity. It can assist clinicians and researchers who work in fields related to child treatment or development.

The purpose of this paper is to investigate how evaluation of sales promotion is affected by consumer's perception on sale promotion tools(SP). Perception on SP is supposed to be classified into reduced loss and separate gain according to characteristics of SP, that are benefit realization period(immediate vs. remote), easy to calculate cash value(easy vs. difficult), and purchase occasion(concurrent vs. different). Hypothesis testing using ANOVA and structural equation model about data that is collected from college students based on experimental design, reveals that immediate realization and easy calculation make SP tool perceived as reduced loss. And perception as reduced loss is more effective to be evaluated as high value and lead to purchase intention.

Occupational Stress is defined the stress which occurs in the workplace or organization. In Korean workers, the rate of occupational stress was 87.8% which was the highest level among OECD countries(average 80.0%). The purpose of this study was to examine the empirical verification of the Korean Occupational Stress Scale(KOSS) in physical therapists. For this purpose, the subject of this study was set up physical therapists who were working at Gyeonggi province and collected from 388 persons by using purposive sampling. The collected data was conducted explanatory factor analysis and confirmatory factor analysis in order to ascertain factor structure and practical verification of KOSS. Major results were as following: first, the reliability of KOSS was 0.83, and it means that a measure of internal consistency is high. Second, the KOSS result of physical therapists was composed 7 subscales(job demand, insufficient job control, job insecurity, interpersonal conflict, occupational system and lack of reward, organizational climate) and that is more appropriate measurement scale than the original one by using explanatory/confirmatory factor analysis. This study could be contributed as a tool for evaluation and outcome of the basic information of related occupational stress in physical therapists.

This study examined the reliability and validity of the Korean version of the Nurse-Patient Interaction Scale (K-NPIS) for the elderly, at long-term care hospitals in Korea. The original NPIS was developed to identify important characteristics of elderly patient experiences regarding nurse-patient interactions in nursing homes. Totally, 202 hospitalized elderly patients at 4 long-term hospitals in Jinju-si, Suncheon-si, and Namwon-si, were enrolled in the study and completed the questionnaire. For internal consistency, Cronbach's α of K-NPIS was 0.96 after item analysis. K-NPIS was validated using the confirmatory factor analysis and content validity. The content validity score was more than 0.80, establishing the appropriateness and readiness of the tool through group discussions between clinical experts and elderly patients. The K-NPIS is a 10-point scale comprising 12 questions. K-NPIS scores between different residential groups were significantly different, and showed no ceiling or floor effect. The internal consistency reliability, construct validity, and discriminative validity of K-NPIS was adequate. However, criterion validity requires further examination. Our findings suggest that K-NPIS serves as an appropriate measure of nurse-patient interaction when applying the nursing care intervention for elderly.

The purposes of this study are to explore Iceberg(IB) model as a systems thinking analysis tool for high school students, suggest a systems thinking analysis method using rubrics and verify its validity and reliability. For this study, the theoretical basis was examined through literature analysis about IB model and rubrics of evaluating the systems thinking. And 6 high school students participated in IB model activity and were interviewed about polar climate change. In addition, quantitative tests using systems thinking scale were also conducted to support the results of the IB model activity analysis. Data obtained from IB model activity was analyzed by using the rubrics of evaluating system thinking developed by Hung (2008). The analysis results were reviewed by two professors to confirm the validity and reliability. In order to confirm the validity, correlation analysis were performed between the rubrics and the quantitative test results. Finding are as follows: Six students used the IB model to express their systems thinking in detail and the results of the systems thinking analysis of students using rubrics showed a distribution of 17~35 points. Furthermore, the results of correlation analysis between rubrics and systems thinking scale was highly correlated (Pearson product-moment is .856) on significance level from .05. Using the IB model introduced in this study, students express their systems thinking effectively and the results of the systems thinking analysis using IB model is considered to analyze validity and reliability. Based on the results of this study, implication suggests how to study the systems thinking in science education.
