The purpose of this study is to develop a scale for evaluation of Parent's Literacy Interaction Rating Scale (PLIRS) for preschool children and to examine its validity and reliability. The participants of this study were 342 Korean mothers with children of 3 to 5 year olds. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between PLIRS and two sub tests of EC-HOME for concurrent validity, and Cronbach's ${\alpha}$ for reliability. The item discrimination was determined by comparing the highest and lowest groups using Chi-square (${\chi}^2$), and Cramer's V. The 25 items of the scale were found to be satisfactory in item discrimination. The concurrent validity was also identified by correlation between PLIRS and two sub tests of EC-HOME. Factor analysis revealed that the structure of the PLIRS consisted of three factors: 'open interaction', 'directive interaction', and 'picture-book reading interaction'. 'Open interaction' is based on 'Whole Language Approach', such as 'I have my child write as he/she likes even if they spell wrongly.' 'Directive interaction' is based on 'Code Emphasis Approach', such as 'I have my child take dictation.' 'Picture-book reading interaction' is how parents read picture-book with her/his children, such as 'When I read a picture book to my child, I ask various questions about a book story.' The Cronbach's ${\alpha}$ for internal consistency reliability range was .78 to .87 for three subscales. It was concluded that PLIRS was valid and reliable to examine the literacy interaction between parents and children in home.

Purpose: The aim of this study was to validate the Korean version of World Health Organization Disability Assessment Schedule 2.0 (KWHODAS 2.0) in 12 item-self administered version (12-self). Methods: The KWHODAS 2.0 and Korean Functional Rating index (KFRI) were tested for internal consistency, ceiling and floor effects, and concurrent validity in 111 patients with low back pain and/or neck pain. Results: A very high level of internal consistency was shown for both instruments; ${\alpha}$=0.96 with KWHODAS 2.0; 12-self and ${\alpha}$=0.97 for KFRI. No ceiling and/or floor effects were found in both the instruments. The KWHODAS 2.0 and KFRI were highly correlated (r=0.77), and the relationship of each item between KWHODAS 2.0 and KFRI was ranging from r=0.09 to 0.72. Conclusion: We conclude that the KWHODAS 2.0: 12-self and KFRI are reliable and are valid instruments for the measurement of disability in Korean speaking patients with low back and/or neck pain. Both instruments, the KWHODAS 2.0; 12-Self and KFRI are now suitable for use in clinical practice and research applications.

Objective: The goal of this study is to develop an instrument for measuring the quality of teacher support for children's play (age 3-5) based on the Play Practice Resources for Teachers presented in the 2019 revised Nuri Curriculum. Methods: The subjects of this study were 333 early childhood educators. Exploratory and confirmatory factor analysis, as well as correlation analysis were all performed to confirm construct validity and concurrent validity. The reliability of each factor was verified using Cronbach's alpha. Results: The Preschool Teacher Play Support Scale (PTPSS) was finalized with 25 items, which included the following four sub-factors: interaction, play materials, play space, and play safety. The concurrent validity was also confirmed through significant correlations between the existing measures such as the Teacher Self-Efficacy Scale, the Teaching Efficacy Scale for Play, and the Teacher-Toddler Interaction Scale. The reliability of each factor was also desirable. Conclusion/Implications: The PTPSS was verified as a sound measure quantifying the play support behavior of teachers who respect the autonomy and initiative of young children which is being pursued by the 2019 revised Nuri Curriculum.

Objectives The purpose of this study is to provide more whiplash injury-specific measurement tools for Korean patients by measuring the validity and reliability of Korean version of Whiplash Disability Questionnaire (WDQ). Methods Bilingual clinicians translated the original WDQ into Korean. After consensus conference between researchers, it was back-translated into English. The pre-final version was completed and administered to 71 hospitalized patients diagnosed with whiplash injury. Validity was evaluated by concurrent validity. Reliability was assessed using Cronbach's ${\alpha}$ and intraclass correlation coefficient. Results The Korean WDQ showed good reliability with high internal consistency and intra-class correlation coefficient (Cronbach's ${\alpha}=0.96$, intraclass correlation coefficient [ICC]=0.82). Concurrent validity demonstrated positive correlations between Neck Disability Index, 36-Item Short Form Health Survey and WDQ. Conclusions The Korean version of WDQ is a valid and reliable tool for use as a measurement of whiplash injury in Korean patients, and it will be a very useful evaluation tool for both clinicians and researchers.

Purpose: To evaluate the applicability of Lasater Clinical Judgment Rubric (LCJR) as an evaluation tool for hypoglycemia simulation practicum on Korean nursing students. Methods: The methodological study was done to evaluate the reliability and validity of the LCJR. Based on Benner's 4 levels of nursing grading rubric, ten items of the LCJR was evaluated for interrater reliability and internal consistency. The content validity was tested by eight experts and concurrent validity was done by Clark (2006)'s clinical simulation grading rubric. Fifty five video-taped cases of senior nursing students in Y University were used for the reliability and concurrent validity of the LCJR. Results: The interrater reliability was r=.90 (p<.001); Kendall tau b=.87 (p <.001), and Cronbach's alpha was .90. A value of item content validity index of the LCJR was .97 and correlation coefficient between the LCJR and Clark's instrument was .90 (p<.001). The mean (${\pm}SD$) of the nursing students' clinical judgment was 2.04 (${\pm}50$). Conclusion: The LCJR is a useful tool to examine the simulation performance evaluation for improving competency among nursing students. The results indicated that the LCJR may provide valuable information regarding clinical judgment of nursing students and thus, suggested to use to develop a simulation-based education program.

Objective : The experiences in close relationships questionnaire-revised (ECR-R) (Fraley, Waller & Brennan, 2000) is a valuable tool for measuring adult attachment, and its Korean version, the ECRR-K (Kim, 2004), is widely used in Korea. However, given its substantial length, this study was aimed to develop and validate a short version of the ECRR-K called the ECRR-K14. Methods : Two hundred and ninety-four medical students participated in this study in 2016. They completed the ECRR-K, the Perceived Stress Scale (PSS), the Rosenberg Self-Esteem Scale (RSES), and the UCLA Loneliness Scale (UCLA-LS). The study authors applied the Rasch rating scale to check each item's model fit and then performed confirmatory factor analyses (CFAs) to test the new scale's validity. Results : The authors selected seven items each for the anxiety and avoidance subscales, and the ECRR-K14 showed fair to good internal consistency (Cronbach's ${\alpha}=0.93$ and 0.92 for anxiety and avoidance, respectively). The anxiety subscale showed concurrent validity with the PSS and the RSES while the avoidance subscale showed concurrent validity with the UCLA-LS. The CFAs also demonstrated the validity of the model with a goodness-of-fit index of 0.916. Conclusion : The ECRR-K14 showed excellent reliability and validity and appears to be a promising instrument for measuring the two attachment dimensions in adults.

In the sense of eigenstructure (eigenvalues/eignenvectors) assignment, the effectiveness and disturbance suppressibility of a controller depend mainly on the left eigenstructure (eignevalues/left eigenvectors) of a system. On the other hand, the disturbance decouplability is governed by the right eigenstructure (eignevalues/right eigenvectors) of the system. In this paper, in order to obtain a disturbance decouplable as well as effetive and disturbance suppressible controller, a concurrent assignment methodology of the left and right eigenstructure is proposed. The biorthogonality condition between the left and right modal matrix and state selection matrices are used to develop the methodology. The proposed concurrent eigenstructure assignment methodology guarantees that the desired eigenvalues are achieved exactly and the desired left and right eigenvectors are assigned to the best possible (achievable) sets of eigenvectors in the least square sense, respectively. A numerical example is presented to illustrate the validity and usefulness of the proposed methodology.
