Objectives: The objectives of this study were to investigate the agreement between medical history questionnaire data and claims data and to identify the factors that were associated with discrepancies between these data types. Methods: Data from self-reported questionnaires that assessed an individual's history of hypertension, diabetes mellitus, dyslipidemia, stroke, heart disease, and pulmonary tuberculosis were collected from a general health screening database for 2014. Data for these diseases were collected from a healthcare utilization claims database between 2009 and 2014. Overall agreement, sensitivity, specificity, and kappa values were calculated. Multiple logistic regression analysis was performed to identify factors associated with discrepancies and was adjusted for age, gender, insurance type, insurance contribution, residential area, and comorbidities. Results: Agreement was highest between questionnaire data and claims data based on primary codes up to 1 year before the completion of self-reported questionnaires and was lowest for claims data based on primary and secondary codes up to 5 years before the completion of self-reported questionnaires. When comparing data based on primary codes up to 1 year before the completion of selfreported questionnaires, the overall agreement, sensitivity, specificity, and kappa values ranged from 93.2 to 98.8%, 26.2 to 84.3%, 95.7 to 99.6%, and 0.09 to 0.78, respectively. Agreement was excellent for hypertension and diabetes, fair to good for stroke and heart disease, and poor for pulmonary tuberculosis and dyslipidemia. Women, younger individuals, and employed individuals were most likely to under-report disease. Conclusions: Detailed patient characteristics that had an impact on information bias were identified through the differing levels of agreement.

In many fields, Kansei engineering, often called Human Sensibility Ergonomics, has been applied to the product development for customer's satisfaction. Also, it may use to a lot of products and environments related to human's convenient life. If the measurement and the validation of human sensibility are accomplished subjectively and qualitatively, then a good design is expected. This paper considers an application of one of the Kansei engineering's techniques, extraction and categorization of the sensory words, to the products of mobile telecommunication units. First, 1st sensory words were extracted from Korean dictionary, catalogues, pamphlets, etc. Second, 2nd sensory words were extracted from the questionnaires, elimination of synonym, advise of expert, etc. Third, final sensory words were extracted from questionnaires, etc. Fourth, ask to answer the questionnaires with the extracted words in the five-grade semantic differential. Finally, The factor analysis is used to categorize the extracted sensory words, and shows that the words can be grouped into some categories.

This study aimed at developing the standard questionnaire database system for rural development. By the previous study for the hierarchical listing of the factors related to rural development in the village level, the targetting questionnaire items pool was proposed. The data base system basically consisted of 3 parts: general, principal and sectoral parts for rural development. General and principal parts had the detailed questionnaires without any further hierarchy, but sectoral one 4-step hierarchy from high/medium/low levels to detailed questionnaires. Tentatively, total 417 questionnaires statements were written with 5 questioning styles: single choosing, multiple choosing, tabular, writing and special questions. Through the checking done by college students team from rural area, the database system having 467 questioning statements was finally developed.

The article analyzes the impact of factors affecting the environmental accounting of enterprises in the food and beverage industry in Vietnam, providing more empirical evidence on factors affecting environmental accounting. The research method uses a questionnaire survey of managers at all levels, chief accountants, and cost accountants, of 56 enterprises in the food and beverage industry. The survey results collected 268 questionnaires. After eliminating the invalid questionnaires due to many blank cells, the author chose to use 236 questionnaires. Quantitative research was carried out with SPSS 25 software. Research results show that all 6 factors positively affect environmental accounting, which includes Firm size, Stakeholders, Awareness/Knowledge of leaders, financial resources, Qualifications of staff, and Regulations, in which stakeholders and leaders' perceptions are the most influencing factors. Based on the research results, the author has proposed recommendations to improve the ability of enterprises to successfully implement environmental accounting in the food and beverage industry, thereby contributing to improving the operational efficiency of the food and beverage enterprises. The Vietnamese market is very potential, so the Government, authorities, customers, investors, etc., contribute to creating significant pressure to implement environmental accounting in food and beverage enterprises.

A study has been conducted on developing questionnaires to serve as on site diagnostic tools for the early detection of neuropsychiatric impairment among workers chronically exposed to low-level organic solvents. Two drafts of tentative questionnaires have been developed as follows; several question items were selected from questionnaires which were administered to workers exposed to organic solvents in previous studios and were grouped into each symptom category based on the presence of its association using Guttman scaling method, then these selected items were reviewed by neuropsychiatry specialists. The final draft of the questionnaire (total symptom score=36) was developed by selecting 33 question items which had more than a 0.88 Guttman coefficient of reproducibility in each symptom category from a pilot study in which these tentative questionnaires were administered to workers manufacturing soles. Three plants using organic solvents and one plant never using organic solvents as a control group were selected to test the reliability and validity of the developed questionnaires. The major organic solvent in the workplace environment detected by a personal air sampler and GC/MSD nab toluene. The concentration of toluene in air from the department using organic solvent was statistically different from that of the department never using organic solvent. The concentration of toluene from almost all of the workplace did not exceed the allowable level. There was no statistically significant difference between the concentration of urinary hippuric acid from the workers of the department using organic solvent and that of the department never using it. Total symptom score of the plant never using organic solvents was 9.8 and those of the three plants using organic solvents were 15.6, 14.7, and 13,7 respectively. In order to evaluate the validity of the questionnaires, the workers from two different departments of the plant in which usage of organic solvents are totally dofferemt were compared. The total symptom score was 17.8 for workers of the department using organic solvent and 13.5 for the department never using organic solvent and scores of each symptom group between exposure and non-exposure group also showed statistically significant difference. The finding that total symptom score of the exposure group increased as the duration of employment increased indirectly suggests the usefulness of the developed questionnaire to assess the health effects of chronic exposure to organic solvents. The correlation coefficient, which was calculated to evaluate the test-retest reliability, was 0.581 (p=0.001). The coefficient of Crohnbach which reflects the internal consistency of the questionnaire was 0.91. In conclusion, the reliabilty of the questionnaire was well maintained over the time lapse between the two administrations of the questionnaire and despite the seasonal difference.

The significance of self-reported voice assessments concerning patients' chief complaints and quality of life has increased. Therefore, readability assessments of questionnaire items are essential. In this study, readability analyses were performed based on text grade and complexity, vocabulary frequency and grade, and lexical diversity of the 11 Korean versions of self-reported voice disorder questionnaires (KVHI, KAVI, KVQOL, K-SVHI, K-VAPP, K-VPPC, TVSQ, K-VDCQ, K-VFI, K-VTDS, and K-VoiSS). Additionally, a comparative readability assessment was conducted on the original versions of these questionnaires to discern the differences between their Korean counterparts and the questionnaires for children. Consequently, it was determined that voice disorder questionnaires could be used without difficulty for populations with lower literacy levels. Evaluators should consider subjects' reading levels when conducting assessments, and future developments and revisions should consider their reading difficulties.
