Objectives：Developmental reading disorder is a condition which manifests significant developmenttal delay in reading ability or persistent errors. About 3-7% of school-age children have this condition. The purpose of the present study was to validate the diagnostic values of Word/Nonword Reading Test and Letter-Symbol Discrimination Task for the purpose of overcoming the caveats of Basic Learning Skills Test. Methods：Sixty-three reading-disordered patients(mean age 10.48 years old) and sex, age-matched 77 normal children(mean age 10.33 years old) were selected by clinical evaluation and DSM-IV criteria. Reading I and II of Basic Learning Skills Test, Word/Nonword Reading Test, and Letter-Symbol Discrimination Task were carried out to them. Word/Nonword Reading Test：One hundred usual highfrequency words and one hundred meaningless nonwords were presented to the subjects within 1.2 and 2.4 seconds, respectively. Through these results, automatized phonological processing ability and conscious letter-sound matching ability were estimated. Letter-Symbol Discrimination Task：mirror image letters which reading-disordered patients are apt to confuse were used. Reliability, concurrent validity, construct validity, and discriminant validity tests were conducted. Results：Word/Nonword Reading Test：the reliability(alpha) was 0.96, and concurrent validity with Basic Learning Skills test was 0.94. The patients with developmental reading disorders differed significantly from normal children in Word/Nonword Reading Test performances. Through discriminant analysis, 83.0% of original cases were correctly classified by this test. Letter-Symbol Discrimination Task：the reliability(alpha) was 0.86, and concurrent validity with Basic Learning Skills test was 0.86. There were significant differences in scores between the patients and normal children. Factor analysis revealed that this test were composed of saccadic mirror image processing, global accuracy, mirror image processing deficit, static image processing, global vigilance deficit, and inattention-impulsivity factors. By discriminant analysis, 87.3% of the patients and normal children were correctly classified. Conclusion：The patients with developmental reading disorders had deficits in automatized visuallexical route, morpheme-phoneme conversion mechanism, and visual information processing. These deficits were reliably and validly evaluated by Word/Nonword Reading Test and Letter-Symbol Discrimination Task.

The purpose of this study was to test the reliability and validity of the Korean version of the fear of daily activities questionnaire (FDAQ) for low back pain patients. Seventy-three subjects with low back pain were participated in this study. The subjects completed ten standardized self-administered questionnaires that measure fear of specific daily activities. The reliability of the acquired data was determined by the intra-class correlation coefficient (ICC) and the Cronbach's ${\alpha}$ for internal consistency. Constructive validity was analyzed by factor analysis, and concurrent validity was acquired from comparison FDAQ scores to the visual analogue scale (VAS) and Oswestry disability index (ODI) scores. The test-retest reliability of the Korean version of the FDAQ showed good ICC (2,1)= 0.96 (95%CI 0.94.0.98) and Cronbach's alpha value was 0.93. Factor analysis suggested two factors solution consisting of spinal loading and spinal movement/posture, it explained 76.1% of the total variance. The concurrent validity was moderately related with pain and disability. Therefore, the Korean version of the FDAQ is a useful method for measuring the fear of daily activities of patients with low back pain.

Objective : This study aimed to develop a Korean version of the HLS-EU-Q47 that deals with the concept of health literacy based on the understanding, apply/use, process/appraisal, and access/obtain to health information. The purpose of this study is to confirm the level of comprehensive health literacy of the elderly in Korea using this tool. Methods : After going through the Korean interpretation process of HLS-EU-Q47, the items were confirmed through content validity verification by experts. The completed Korean-HLS-EU-Q47 (K-HLS-EU-Q47) was applied to 254 elderly people in the local community to analyze the degree of internal consistency and reliability. Furthermore, a comparative analysis based on the general variables was conducted. Results : The internal consistency of this tool for the elderly yielded Cronbach's 𝛼 of .81~.91, indicating a high level of reliability. There was a difference in health literacy according to sex and age based on general characteristics. Men had higher health literacy than women, and with increasing age, health literacy decreased. Conclusion : In this study, the K-HLS-EU-Q47 was developed to assess the comprehensive health literacy level of the elderly in Korea. It is expected that the search for ways to maintain a healthier life for the elderly through understanding the health literacy levels of the elderly using the results of this study will become more active.

This study was designed to develop the scale of paternal parenting attitudes which has become an area of interest in child fostering study recently. Considering various factors extracted from previous Korean and foreign studies, the authors constructed a questionnaire composed of total 57 questions. It was applied to 126 mothers from families with no psychiatric patient in Seoul and Pusan who had at least onechild older than age 12 by random sampling. Then the authors extracted the factors which were able to compose the scale and evaluated the concurrent reliability. Also the authors selected mothers of 47 schizophrenic patients and 29 bipolar I patients diagnosed with the criteria of DSM-IV who have treated in Seoul National Mental Hospital and 46 controls which consisted of randomly selected mothers from normal families for the discriminative validity test. The results were as follows. The authors extracted 5 subscales of active participation, democratic guidance, warmth, hostility, devotion for education and Cronbach’s ${\alpha}$ value of each subscale which shows its internal consistency was .82, .78, .65, .78, .61 respectively. In the discriminative validity test, all subscales except ‘devotion for education’ subscale significantly discriminated between fathers of schizophrenics and control group. Furthermore ‘active participation’ subscale and ‘warmth’ subscale showed significant difference between fathers of control group and resting both father group of schizophrenics and biopolar I patients.

The purpose of this study was to examine the relationship of the critical thinking disposition of paramedic students to their satisfaction with hospital clinical practice and intention of recommendation. As for data analysis, the statistical packages SPSS WIN 20.0 and AMOS 20.0 were employed, and frequency analysis, factor analysis, multiple regression analysis and structural equation modeling were utilized. Besides, Cronbach alpha coefficients were calculated to check item internal consistency. The level of significance was all set at .05. A survey was conducted to collect data from May 12 to August 25, 2012, and the answer sheets from 305 respondents were gathered and analyzed. The critical thinking disposition of the paramedic students was found to have a significant impact on their satisfaction with clinical practice, and the hypothesis about that was accepted. Their critical thinking disposition was found to exert a significant influence on their intention of recommendation as well, and the hypothesis about that was accepted. Finally, their satisfaction with clinical practice was found to affect their intention of recommendation in a significant way, and the hypothesis about that was accepted. The findings of the study suggested that in order to nurture professional and competent paramedics, the content of clinical practice should systematically be managed on a regular basis, and prolonged research efforts should be directed into program development.
