  • The internet survey methods have been more and more widely used as the coverage of the fixed-line telephone is being reduced due to the diffusion of mobile phone. So, there is a need to know the accuracy of this new survey method. This study aims to estimate the accuracy of the internet survey method and identify the factors affecting the accuracy of this method, For this purpose, we analyzed the election poll data during the 17th general election period. These data include fixed-line telephone survey data, internet survey data, mobile phone survey data and the election voting data. The analysis shows that the prediction errors of the internet survey were a little more than those of the telephone or mobile phone survey. But the differences are not significant. It follows from this result that we can use the internet survey method in social survey context. This study also found that the respondent's willingness to participate in the survey, the probability of being at home during survey and the respondent's educational level were affecting the accuracy of the internet survey. Further studies to develop weighting method with these factors are needed.

  • As modern society has become specialised and complex in all areas of politics, economy and society, it has reached a point where it is difficult to control crime with the general public power. Private security, which began to fluctuate after the 19th century, has expanded its scope to subsidise public power in various areas, sometimes beyond public power. Among these private security activities, the private investigate system has long been used to provide private investigate services that are safe from personal human rights protection and crimes. This study investigate the private investigation system in the United Kingdom and South Korea focusing on the missing person investigation system by using the qualitative content analysis of research methods. First, the results of the qualitative content analysis are described through methods such as literature reviews and interviews on how the British private investigation system and the missing persons search system are implemented. Next, the results of the content analysis are presented through the methods of literature reviews and questionnaires on how the implementation of the civilian survey in Korea and the search for missing people is proceeding. It is a very important field in both countries, and there is a very limited study, especially from a Korean perspective. Therefore, it is expected that this study will not only facilitate discussions for the successful legalisation of the private research system, but also provides a basic foundation for future research. The study of the private research system should be ongoing and periodic, not temporary. In addition, in order to introduce Korea's private survey system, the private investigation system should be developed by discovering the problems of the Private Investigation Law mentioned in this study and collecting opinions from citizens, academics and related institutions. The introduction of the private investigation system requires the connection of the efforts and interests of citizens, academia and related institutions.
