  • This study shows the results of constructing panel data using Farm Household survey and presents some examples of empirical application. This study shows that ex post constructed panel data using repeated cross-sectional survey can be used in various dynamic analyses. This paper also shows that the well known difficult problem of longitudinal weights can be easily solved by using the existing cross-sectional weights in original cross-section data. Based on these results, we propose that the National Statistical Office not only try to construct panel data, but also construct panel data by using existing repeated cross-section data. The benefits of this approach seems to be very big in establishment survey.

  • 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.

  • The Korean Academic Multimode Open Survey (KAMOS) is a national survey first conducted in 2016. Stratified cluster random sampling was used in an initial face-to-face survey during which panel members were recruited. The second survey allowed invited panel members to answer online or by phone. KAMOS includes both longitudinal items and omnibus items, i.e., researchers can propose questions to include on KAMOS. This paper seeks to establish that KAMOS is representative of the South Korean adult population. The demographic variables from the first survey were comparable to demographic variables from two well-respected surveys in South Korea: the KOSTAT Social Survey and the Gallup Korea Omnibus Survey. To ensure that there was no substantial difference between those who answered the first survey and those who answered the second survey, we compared the results of 22 items from the first survey. The 2,000 panel members who were invited to participate in the second survey had similar responses to the 1,008 of those who responded to the second survey. Based on our findings, KAMOS can be considered a representative sample.

  • This paper discusses the central issues of election studies and in this contort, suggests the panel survey method as an alternative to general opinion surveys. In doing so, it also explains the advantages and benefits that a panel survey provides, and discusses the weakness of the 2006 panel survey. East Asia Institutes, constructing the consortium which includes JoongAng Ilbo, SBS, and Hankook Research, traces the change in voting decisions during the 2006 Korean Local Elections. Four regional panels, focusing on the gubernatorial elections in Seoul, Pusan, Kwangju, and Chungnam, enable researchers to study the critical issues of election studies such as the causal relations among a set of voting determinants, the impact of campaigns, and the characteristics of floating voters.

  • In this paper we used the KLIPS(Korean Labor and Income Panel tudy) data that surveyed from 2006(wave 9) to 2009(wave 12). Other previous studies are concerned with the panel attrition in the early wave, but this study classifies the response pattern and investigates some factors that influence panel attrition when the panel tends to stabilize. It was revealed that panel attrition was influenced by relocation and housing type through the logit model. Besides it was appeared that panel attrition was affected by the monthly living expenses and the overall household income through the decision tree.

  • The purpose of this paper is to explain characteristics of panel data and display the academic cases using panel data. Panel data have merit to control various variables to influence respondents' attitude and estimate the effects of independent variables researchers are interested in by surveying the same respondents several times. However, panel data also have problems such as contaminating the respondents and reducing the number of the respondents as survey conducted several times. In spite of a few inherent problems of panel data, informations that panel data provide are valuable and some research themes could not be possible without panel data. This paper investigates the relationship between interest in elections and voting. Electoral stimulation such as watching TV debates influences the consistent voting intended. But changing nonvoters who had voting intention but not vote are not influenced by the electoral stimulation.

  • This paper suggests a new method of compensating for wave nonresponse in panel survey, which combines weighting adjustment and imputation. By deleting less frequent nonresponse patterns, we can get simplicity. A new mean estimator under the new combining method is provided and a limited simulation study employing a real data is conducted.

  • It would cause a serious problem in the panel data when panel attrition is concentrated on certain socioeconomic groups. Using the GOMS, this study investigates whether there exists non-random attrition bias in the data and seeks for feasible solutions to minimize the bias. The results of logit analyses show that panel attrition in the GOMS results mainly from surveying system but not from the surveyed. Therefore, the result suggests to develop well-organized management skill and systems as well as to construct weighting methods.

  • The purpose of this study was to examine dental care utilization and expenditures among children aged 0 to 19 years using Korea Health Panel Survey (KHPS) data in 2008 - 2013. Weighted estimates were nationally representative and statistical significances were analysed by $x^2$ test or adjusted Wald test using STATA 13 software. While dental care utilization increased steadily among children from 2008 through 2013, less than one-third the children received dental care in 2013. Compared with 2008, the proportion of restorative care, oral surgery, preventive care decreased and the proportion of orthodontic care, prosthetic care increased. While the proportion of amalgam markedly decreased, the proportion of resin increased. This study highlight socioeconomic disparities in dental utilization and expenditures among children. Especially the findings provide a baseline assessment for examining trends on dental care for children in the future.

  • The purpose of this paper is to design and implement a Computer Assisted Personal Interviewing (CAPI) system for Panel Survey of Employment for the Disabled (PSED) using Blaise software developed by Statistics Netherlands which is a powerful and flexible system used for computer-assisted survey processing. CAPI system for PSED is consisted of three parts, which are survey management program, electronic questionnaire program, and postprocessing program. These programs are constructed with modular approach and are integrated into CAPI system. The developed software is highlighted in its reusability which results in the improved efficiency and reduced cost of software maintenance. CAPI system for PSED proved its effectiveness in carrying out the survey by guaranteeing correctness of survey data, improved timeliness of survey, easy reforming the questionnaires, easy control on the interviewers, and rapid data processing in spite of the complexity of PSED.
