The purpose of this study is to develop questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. To do this, we investigated the personality traits required to successfully conduct flight training for 30 flight instructors as a subject. The results were as follows: motivation, concentration, concentration, situational awareness, and concentration. Based on this, preliminary 300-item questionnaire was prepared by combining the existing studies related to pilot aptitude. Survey was conducted using preliminary questionnaire for 152 student pilots as a subject. As a result of the correlation analysis between the results of the questionnaire and the flight training, 16 questions were derived. Finally, factor analysis showed that the final 14 questionnaire items were confirmed. The internal concept of an item is categorized as personality, perception, and motivation. This study suggests that the pilot aptitude should be viewed from an extended point of view by analyzing individual characteristics and pilot aptitude in relation to flight training achievement.

This study was conducted to develop and evaluate the reliability and the validity of a questionnaire in order to determine the applicability as a screening tool for estimating environmental exposure and health effects related to air pollution. The questionnaire was developed with adopting some items of others such as ISAAC or ATS-DLD. And then we performed test-retest to 89 middle school students and their mothers at interval of three months. Cohen's Kappa values, weighted Kappa values, Spearman's correlation coefficients, and Pearson's correlation coefficients for each item were computed as reliability coefficients. The validity coefficients and validity coefficient bounds were also obtained by simply using these reliability coefficients. As results, Kappa ranged broadly from 0.10 to 0.61 of the items 'diet', $0.52\sim0.79$ of the environmental tobacco smoke, $0.39\sim0.44$ of the functional categories of surrounding environment, and $0.39\sim0.44$ of the using transportation systems; these items were regarded as confounding factors. For items related to health outcomes, Kappa ranged from -0.02 to 0.37 in the respiratory system of past medical history, and from 0.11 to 0.55 in the current health status. But Kappa of the others were over 0.60. In conclusion, if some items can be corrected or modified, the questionnaire developed in this study can be used as a tool for evaluating environmental exposure and health effects associated with air pollution.

Purpose: This study has focused on evaluating the effectiveness and accuracy of the questionnaire which considered as a basic data to indentify constitution Methods: By analysing the tendency of the respondents who has defined constitution by clinical diagnosis and comparing of their answers, the result of their constitution analysis by our questionnaire were re-examed. The answer of each question to each constitution were tested how it is relevent to a scale of a constitution. So I analysed each item response rates on QSCCII of those who had been tested and diagnosed as Taeyangin, Soyangin, Taeumin, Soeumin respectively. Results: 1. From the 537 results of QSCCII of those who were examined by professors, I made a selected Taeyang scale which is consists of 18 items, a selected Soyang scale which is consists of 40 items, a selected Taeum scale which is consists of 41 items and a selected Soeum scale which is consists of 32 items. 2. I have found that there is limitation to find out constitution by the questionnaire we used, one I hope that suitable questionnaire will be developed for the research in the future

Purpose: This study developed a Korean sentiment questionnaire by adapting an existing English survey using focus group interview (FGI)-based cognitive interview (CI) techniques to investigate the utilization of outcome measures (OMs) among Korean physical therapists. Methods: The existing OMs survey questionnaire was adapted by dividing eight physical therapists into two groups: mid-experienced (n=4) and high-experienced (n=4). Each group participated in a 120-minute FGI-based CI session. All interviews were recorded, and the researcher transcribed the data immediately after each interview. The data were then organized and categorized into themes using Excel 2021 and verified with the participants. Results: FGI-based CI sessions were conducted with Korean physical therapists to revise the English version of the questionnaire, tailoring it to the local context. Four main themes emerged from the interviews: inappropriate items or translations, questionnaire length and organization, questionnaire improvements, and additional items. The questionnaire was revised based on the feedback obtained during these interviews. Conclusion: The questionnaire was modified according to the themes derived from the interviews. The questionnaire was developed to represent the clinical environment of Korean physical therapy accurately by removing elements of the questionnaire unsuitable for the Korean sentiment and incorporating the perspectives of Korean physical therapists.

Objectives: The study purpose was to test the validity and reliability of the core emotional assessment questionnaire based on the seven emotions. Methods: Survey data were from 651 individuals and contained 141 items determined from a previous pilot study. Among the participants, 241 were retested. First, following analysis of the internal consistency reliability of the 141 items, we deleted items with Cronbach-$\alpha$ coefficient below 0.5. We then selected 100 final items after the first factor analysis. Second, the final 100 items were evaluated by internal consistency reliability, test-retest reliability, factor analysis, and correlational analysis. Results: Cronbach-$\alpha$ coefficient for the final 100 items were 0.866~0.956 and the test-retest reliability were above 0.70. The 100 items categorized into 7 factors explained 53.8% of the total variance. Analyzing the correlation of each chiljeong, we had a high positive correlation above 0.70 between sa and bi, bi and u, gong and kyeong. Conclusions: The final 100 items used for the core emotional assessment questionnaire based on the seven emotions showed satisfactory reliability and validity. Thus, it may be an appropriate instrument for measuring Chiljeong in the general population.

The aim of this study was to measure the brand images of contract foodservice management companies by identifying brand image attributes and then developing a measurement scale to measure the weight of these attributes. The measurement scale was developed by following a 5-stage process that included face-to-face interviews with experts, literature review, questionnaire surveys, verification of scale validity, exploratory factor analysis, and confirmatory factor analysis. A total of 137 items measuring brand image were collected: 37 items from studies of brand image and corporate image, 55 items from studies of contract foodservice management companies and 45 items from the internet and websites of contract foodservice management companies. A survey was then conducted to assess the validity and reliability of the questionnaire items. Ultimately, the 137 items were reduced to 40 items. The calculated Cronbach's alpha for the 40 brand image items was 0.934, demonstrating good internal consistency. Based on exploratory factor analysis (EFA), employee attitude, menu content, corporate image, dining location and ambience, along with 33 subattributes, were identified as brand image attributes. Employee attitude was the most significant attribute influencing brand image. After confirmatory factor analysis (CFA) and a review process, four brand image attributes and 33 subattributes were finalized and incorporated into the scale.

To develop an effective and efficient measurement system for tracking changes of functional status across two measures, it is essential to integrate information and communicate scores across two measures. The lack of communication between two measures leads to score incompatibility. A potential solution would be the development of a crosswalk table between those measures. Prior to creating a crosswalk table, selecting common items between two measures is critical. By using the Oswestry low back pain disability questionnaire (Oswestry) and a short form measuring disability resulting from low back pain, item level statistics as well as differential item functioning (DIF) using the Rasch measurement were investigated. Eighty-two participants with known group validity were recruited. Based on the application of the Rasch measurement model, item difficulties across the two measures were logically and hierarchically ordered. Ceiling effects for both measures were detected, which were not be able to be effectively measured with the two measures. The DIF analysis across the two measures confirmed that five paired items were found to have DIF and five common items were selected for common items. Although five paired items function differently across the Oswestry and the short form, all items of both measures were well targeted study participants. The common items selected by the Rasch measurement model may be effective when creating a crosswalk table between the Oswestry and the short form.
