The purpose of this study was to develop a measurement tool for education satisfaction of sport ethics program and to verify its validity. To achieve this goal, 3 steps of experimental processes were carried out. In the first step, the pilot questionnaires was created on the basis of previous researches regarding sport ethics education, education satisfaction, and response assessment. In the second process, as a pilot survey step, construct validity was obtained through exploratory factor analysis and confirmatory factor analysis of the measure constructed by the first process. In the third process, as a main survey step, external validity was obtained through difference verification, then questionnaires were constructed based on the analyzed contents. As a result of these steps, a measurement tool for educational satisfaction of sport ethics program composed of 17 questionnaires was developed. It consists of education contents (6), instructor competency (5), and education effect (6).

Background: The Functional Gait Assessment (FGA) was developed to measure of gait-related activities. The FGA was translated in Korean but only a few psychometric characteristics had been studied. Objects: The purpose of this study was to evaluate the validity and reliability of the Korean version of FGA scale using Rasch analysis. Methods: The study included 120 patients with stroke (age range=30~83 years; mean${\pm}$standard deviation=$58.3{\pm}11.1$). The FGA and Berg Balance Scale were performed, and were analysed for dimensionality of the scale, item difficulty, scale reliability and separation, and item-person map using Rasch analysis. Results: The 4 rating scale categories of FGA were satisfied with optimal rating scale criteria. The most items of the FGA showed sound item psychometric properties except 2 items ('gait with the horizontal head turns', and 'gait with narrow base of support'), and the 2 misfit items were excluded for all further analyses. The 8 items were arranged in order of difficulty. The most difficult item was 'gait with eyes closed', the middle difficult item was 'gait level surface', and the easiest item was 'gait with vertical head turns.' A person separation reliability was .93 and the person separation index was 3.57. Conclusion: This study suggests that the 8-item Korean FGA are valid measure of assess the gait-related balance performance, and to set the goal of rehabilitation plan in patient with stroke.

Recently, multiple glazing units, frames, complex fenestration systems, and windows with shading devices have been developed to save cooling energy in buildings. However, very little work has been conducted on developing a direct experimental test method of the solar heat gain coefficient(SHGC) for new fenestration techniques. This study aims to develop and evaluate a test apparatus to measure the SHGC, according to the KS L 9107 test method. The performance of the solar simulator was class A, B, and A, for spectral match, non-uniformity, and instability irradiance, respectively. The differences between the measured and calculated SHGC values were found to range between 0.001 and 0.011, and for all test specimens they agreed within 4%. These results establish the validity of the test apparatus. This system is thus expected to be useful in assessing the energy performance for various types of fenestration.

The purpose of this study was the development of the parenting stress scale, necessary to understand the details of the difficulties for a working mother having children from infant to preschooler. Relevant works were reviewed to collect 44 items for the questionnaire from the previous researchs, and additional 34 are combined as a set of measure items. The 78 items were analyzed for the fitness of structure based on the chi-square test and Cramer's V coefficients, and 35 were selected as a final set for the questionnaire. Further factor analysis on the 35 items showed that they could be selected 32 items of the 35 item scale and composed of 3 subscales; namely, the first factor(12 items) as‘typical stress due to the parenting’, the second(12 items) as‘pressures pertaining to the parental role and distress’, and the third(8 items) as’guilty to the parenting by others’. This final questionnaire composed of 32 items was also tested for the concurrent validity based on Pearson's correlation with Goldberg's General Health Questionnaire (GHQ), which is a well-known index to represent the socio-psychological stress. The correlation factor is .41(p＜.001), which justifies the fitness of the newly designed questionnaire. To find the confidence level, the Cronbach α was evaluated, which results .88 for the overall questionnaire and ranges between .76 and .82 for each subcale. This parenting scale can be also utilized as a measure to exploit proper programs for the parent-child relations, parent education and rehabitilation of the family function.

The purpose of this study was to identify construct validity and reliability of instrument for professionalism in physical therapy using developed by American Physical Therapy Association for 470 physical therapists. The corrected data was analysed using confirmatory factor analysis and internal consistency. Model of professionalism was adequate (p<.05) and consisted of 7 factors. Standardized coefficients of construct factor were followed by the integrity (${\beta}$=.93), professional duty (${\beta}$=.92), and compassion/caring (${\beta}$=.86). There were significant difference in professionalism by career(p<.05) but not significant difference by sex(p>.05). Also, the internal consistency for sub-factor of professionalism demonstrated adequate reliability of the measure (Cronbach ${\alpha}$=.80~.96). Because instrument for professionalism in physical therapy have a validity and reliability, it is useful for measuring professionalism in physical therapists.

In this study, we investigated protection motivation and behavioral intention to prevent serious illnesses related to excessive sodium intake among the university students in Gyeongnam and Busan. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to the threat of serious diseases due to the high sodium intake as well as the effectiveness of preventive measures (response efficacy), and the ability to perform them (self-efficacy) along with their willingness to follow recommendations (behavioral intention). Data was collected in June 2015. Study participants were divided into either low (n=117) or high (n=177) sodium intake behavior groups based on their current behaviors. Exploratory factor analysis was performed to measure construct validity and Cronbach's alpha was calculated to check reliability of measurement items. The high sodium intake behavior group perceived higher vulnerability than the low sodium intake behavior group among four PMT factors. Differences of the other three factors were not significant between the two groups. The results of hierarchical regression analysis indicated that self-efficacy and response efficacy affected behavioral intention of high sodium intake behavior among students. Hence, development of strategies to increase self-efficacy and response efficacy are strongly recommended.

The Functional Independence Measure (FIM) is widely used to determine the dependency of activity of daily living in rehabilitation patients. The purposes of this study were to evaluate the unidimentionality of the FIM physical items and to analyze the validity of cross-functional levels in stroke survivors in Korea. Thirteen physical items of FIM were rated according to an ordinal scale of a 7-level classification. Two hundred and seventy-nine patients participated in the study (age range 18~92 years and 57% male). Six items-eating, bladder control, bowel control, transfer to and from the bed/wheelchair, transfer to and from the toilet, and bathing-showed misfits with the Rasch model. The most difficult item was 'bathing', the easiest item was 'bowel control'. Although there were several differences within functional levels, the hierarchical order of item measures was rather similar. 'Bathing' was the most difficult in high level patients (above 60), however 'stairs' was most difficult in the middle level (41~60) group. In the low level group (below 40), 'toileting' was the most difficult. In conclusion, the present study has shown several differences of item difficulty among functional levels. This result will be useful in planning interventions, and developing rehabilitation programs for stroke survivors.

In this study, we develop a scale to measure brand image attributes related to the symbolic use of fashion brands, and then, test the validity and reliability of the scale. In Study 1, a comprehensive literature review was conducted to generate the initial set of measurement items. Nominal Group Technique was subsequently conducted to refine the measurement items in a qualitative way. In Study 2, an expert survey was performed to further refine the measurement items in a quantitative way. In Study 3, a consumer survey was performed to determine the final set of measurement items and validate it. The scale of brand attribute symbolism consists of 21 items with six factors (i.e., Strength, Intellect, Cheerfulness, Traditional Femininity, Nature, and Affordability). The six-factor, 21-item scale is found valid and reliable. Implications, limitations of this study, and suggestions for future research are also discussed.
