Purpose: A large number of attributes with mixed levels are often considered in the conjoint analysis. In the cases where attributes have two or three levels, we research on the efficient design of survey questionnaire to estimate all the main effect and two factor interaction effects with a reasonable size of it. Methods: To reduce the number of questions in a questionnaire, the balanced incomplete block mixed level factorial design with minimum aberration was proposed by Lim and Chung (2016). Based on the number of questions and that of the respondents in that design, D-optimality criterion is adopted to find efficient designs where the main effect and two factor interaction effects are estimated. Results: The list of the number of questions and that of the respondents in efficient designs for survey questionnaire are recommended based on the D-efficiency of each design and the proposed selection criteria for the number of both questions and the respondents. By analyzing all the respondents survey data generated by the simulation study, we find the proper model. Conclusion: The proposed methods of designing survey questionnaires seem to perform well in the sense that how often the proper model is found in a simulation study where all the respondents survey data are generated by the simulation model.

A survey was conducted on 300 working women(one woman/company) who specialize in STEM(Science, Technology, Engineering and Mathematics) in the Busan region(south of Korea) to determine their job satisfaction. The overall response of women working in industry is relatively positive although they do experience a certain limit as female workers. The serious difficulties are long work hours and restriction of behavior in consequence of being the minority. Respondents anticipate an increase in number of working women in the STEM field due to the enforcement of women resource policies in Korea. Survey results about career development show that some of the most important factors in professionalism are responsibility, gumption and cooperation. The expectation of promotion is very low. Sexual discrimination is distinctly appearing in wages and promotions. If they decide to quit their job in the midstream, the key reason is in the difficulties of compatibility between home and occupation. Survey results about job satisfaction to work in industry reveal that 31.0% of respondents are satisfied because their job is consistent with their specialty; 30.7% of respondents are working where they wanted. Among respondents who intend to change their job, only 20.7% of respondents wanted to keep their specialties. Two factors involved in the respondents' satisfaction during work are special technical achievement and practical application of their knowledge. But, they are unsatisfied in terms of implementing their leadership.

Even though panel surveys are very useful in estimating the change between time points, they suffer from sample distortion as survey rounds proceed due to panel attrition and conditioning. This study is to report the statistical aspects of KBS-MBMR's five-rounds panel survey for the 2007 Presidential Election of Korea. Main findings are as follows. First, the attrition propensities were higher among women, among the young and the old aged, and among "None"/"Don't Know"/"Won't Say"(DK) respondents for the question asking preferred candidate. Second, there existed the conditioning effect that pushes the respondents to choose one candidate in hurry. Third. repeated measurements of the survey did not influence panel respondents on the choice of preferred candidate. if DK respondents are set. aside, and on the final voting intention of panel respondents.

A point based speed enforcement system(SES) has been widely used in roadways to reduce the operating speeds and potential traffic accidents. Recently, the needs for introudcing new SES using point-to-point speed measurement was presented, however, no practical guidelines or justification of the system was available. This study investigated the effectiveness of the current SES and introduction of the new SES through user interview survey method. Survey results showed that 33% of respondents were unsatisfactory to the current way of SES operation, which was 11% higher than satisfactory respondents, and about 70% of the respondents supported the introduction of point-to-point based SES operation. A majority of respondents preferred the straight roadway segment, bridge and tunnel, and curved roadway segment for a start application site with the segment length of 1-5 km long. Using these survey results, an introduction scheme was discussed in terms of legal bases, installation criteria, and operational guidelines.

Objectives: An outbreak of humidifier disinfectant-related respiratory disease has not only been a massive disaster for end users, but it is also a concern for the workers of the manufacturers. This study presents the results of a questionnaire survey on the health effects among workers involved in the manufacture of humidifier disinfectants. Methods: Seven sites where humidifier disinfectants were manufactured were identified. A questionnaire survey was conducted to assess the physical symptoms experienced by workers related to humidifier disinfectants. Among a total of 177 workers, 42 subjects were available for the survey. Results: Twenty-one of the 42 respondents reported that they experienced respiratory or skin and mucosal irritation symptoms during work. Of the respondents who experienced symptoms, 14 believed that their symptoms were related to the work process and reported that the symptoms were experienced while working. However, no respondents reported ongoing symptoms or sequelae during the investigation period, and this result could not minimize selection bias due to low response rates. We then compared the characteristics of the group who experienced suspicious symptoms with those of the group without any symptoms. There was no statistically significant difference between two groups. Conclusions: We could not find significant health effects related to the humidifier disinfectant manufacturing process, although 21 respondents experienced stimulant symptoms and 14 respondents believed that the symptoms were related to the work process. Due to the long period of time after occupational exposure and the lack of data, there were many limitations to this study. However, this is one of the few follow-up investigations of workers related to this large-scale disaster in South Korea and the limitations of this study highlight the need to follow up with a nationwide database rather than an occasional survey.
