  • In Korea, quota sampling is mainly adopted in telephone surveys, instead of random sampling which requires call-back procedure and random selection of respondent within households. The contact mode based on the se $x^{*}$age quotas is economically more advantageous and less time-consuming. However, it lacks theoretical ground for valid statistical inference, so that it is hardly accepted in academic circles despite of widely spread practice. Subsequently, survey theoreticians argued that random sampling-based telephone surveys should be tried. In response, Research & Research (R&R), a private research company in Seoul, executed atelephone survey by random sampling mode for the prediction of 2002 Ulsan City Mayor Election. The aim of this case study is to find out various effects of the call-back rule with random selection of respondents by statistically re-analyzing R&R’s Ulsan Survey Data.s by statistically re-analyzing R&R’s Ulsan Survey Data.

  • Korean telephone surveys have been based on telephone directory and thus criticized for considerable under-coverage. Now, Korean survey institutions progress to random digit dialing (RDD) very actively. But still most surveys are administered by quota sampling, prone to assign heavier weights to social classes with more hours staying indoor. As a practical remedy, time-balanced quota sampling scheme was proposed by Huh and Hwang (2006). This study compares two telephone surveys on TV audience environment in Korea: RDD with conventional quota sampling versus RDD with time-balanced quota sampling.

  • This paper examined the electoral polling methodologies such as sampling method, sampling frame and the classification of the don't-know responses. Quota sampling method seemed to be one of the major factors for the declining trust in the poll results. We suggested that new procedures for random sampling as well as the bad number screening procedures for RDD selection of phone numbers need to be developed. Also we reviewed how the KBS used the polls in defining voters' agenda and in communicating the public agenda to the candidates. In Korea, rates for the polls were based mainly on the number of interviews completed. It seemed to keep the polling companies from tim new and more time-demanding polling methods. Also various utilization of the polls are limited by the tendency to keep the questionnaire short.

  • In Korea, telephone surveys have been used in election forecasting since 1992. In some elections, predictions were excellent, but in some elections, the predictions based on telephone surveys were not good. So, exit polls have been used along with the telephone surveys in predicting election outcomes since 2001 by the major broadcasting networks. Though telephone surveys, in general, have been less accurate than exit polls in election forecasting from 2000 to 2003, they were more accurate in the 2004 General Election than the exit polls. All predictions on the winners by the telephone surveys turned out to be accurate. But such success has not persisted. In the 2008 General Election, the telephone surveys was less accurate than the exit polls and actually its accuracy fell clown to the level of the 2000 General Election. This paper tried to find out. the factors responsible for the fluctuation of the accuracy of telephone polls.

  • The purpose of this study is to verify the validation of the Korean-type destructive leadership scale in order to activate the leadership research of local police manager in Korea. For the purpose of this study, the entire police officer(under the rank of sergeant) working at the Gyeongnam Provincial Police Agency in 2017 was set up as the population. A proportional allocation sampling was used for the sampling, and the allocation standard was set up in the workplace, department, rank, and sex. Data collection was conducted from April 1, 2017 to April 30, 2017, for a total of 500 respondents, and 433 were finally used for actual analysis. In the study, reliability and validity of destructive leadership scale were verified through reliability analysis, exploratory factor analysis, and confirmatory factor analysis. As a result, the destructive leadership scale of Korean local police manager showed a high cronbach' ${\alpha}$ coefficient of 0.948 for the questionnaire related load and 0.974 in the questionnaire related organization, but, the model fit of confirmatory factor analysis was low. Therefore, through additional exploratory factor analysis and confirmatory factor analysis, we reconstructed 6 questionnaires by deleting 4 questionnaires among the load-related items. On the other hand, the organization-related items were verified to be appropriate for all of the existing 10 items, and the destructive leadership scale of Korean local police manager was finally reconstructed into 16 items with 2 factors. This study also confirmed that the above reconstruction model is statistically suitable. The destructive leadership scale of Korean local police manager can be used as the basic data of leadership research to be conducted in the future.

  • This study is about the relationship between traditional familism and welfare consciousness in Korea. Traditional familism is known as the value that most Koreans share with, and the impeding value for welfare program development. Strong family solidarity and family-centered perception among Koreans influences other social values and ideology. Especially, care of the family members is understood as a family duty and responsibility. And this inhibits Koreans to develop welfare consciousness and further to develop welfare programs at the governmental level. Thus, this study purposes to explore the relationship between the two. The sample of 1,131 men and women was selected in Seoul area. As a result, traditional familism is found to be quite influential to welfare consciousness among Koreans. First, perception of welfare institution is strongly related with welfare consciousness. The respondents in high familism group showed low welfare consciousness. Second, state-friendly welfare responsibility was shown low in the group of high familism for the aged and youth. In the same context, for the disabled and the unemployed, state-friendly welfare responsibility was shown high in the group of low familism. Lastly, the relationship between familism and the welfare need was not apparent. Such results make possible to conclude that traditional familism among Korean is still influential to welfare consciousness and welfare ideology. However, although this conclusion should not be used for an excuse to avoid state responsibility but used as a tool to develop a welfare model to strengthen family function as one solid family.

  • This study aims to understand public perceptions of aging Korean society and related factors in the context of population aging and generational difference. Data are from 1,498 individuals older than 20 who were recruited through the quota sampling technique. Results indicated that the respondents reported less then three as the number of positive aspects of aging Korean society. Among the factors related to population aging, such as knowledge about aging, perceptions about family care, anxiety about later life, and perspectives about generational conflict, anxiety about later life was shown to be negatively associated with perception of aging Korean society across age groups. Respondents 65 and older showed more positive perception about aging Korean society and this association was conditioned by perspectives about generational conflict. Perspectives about generational conflict revealed positive associations with perception of aging Korean society among respondents aged 20-44 and 45-64, while no association was found among those 65 and older. Discussions focused on ways to alter perceptions of aging Korean society and needs for future research on this topic.
