Thanks to the advantages of low cost and quick results, public opinion polls on election in Korea have been generally conducted by telephone survey, even though it has critical disadvantage of low response rate. In public opinion polls on election in Korea, the general method to handle nonresponses is adjusting the survey weight to estimate parameters. This study first drives mathematical expression of estimator and its bias with variance estimators with/without nonresponses in election polls in Korea. We also investigates the nonresponse rate of telephone survey on 2012 Korea presidential election. The average response rate was barely about 14.4%. In addition, we conducted a survey in April 2014 on the respondents's attitude toward telephone surveys. In the survey, the first reason for which respondents do not answer on public opinion polls on election was "feel bothered". And the aged 20s group, the most low response group, also gave the same answer. We here suggest that survey researchers motivate survey respondents, specially younger group, to participate surveys and find methods boosting response rate such as giving incentive.

The current study examined the effects of the voters' perception of television news coverage of election poll results on their political participation intention. 700 voters participated in a telephone interview three weeks before the 2012 Korean presidential election. A structural equation modeling with the nationally representative sample was performed. The findings indicate the respondents were more likely to evaluate television news coverage of election poll results negatively when the news coverage presented that the candidate they supported was behind in the race, and the negative evaluation was linked to a greater third-person perception. The third-person perception, in turn, had an indirect effect on political participation intention through negative emotional responses. The results imply that voters' political position influences their perception of the television news coverage of election poll results, and this perception can have indirect effects on political participation.

Korean election polls has a history of fifteen years, which may seem too short while those of advanced countries such as the U.S and the UK has a history of one hundred fifty years. However, with various and creative attempts, some of the Korean research companies have developed election polls methods and theories which can be applied to Korean society. They also elevated accuracy of the election forecasts. In spite of short history the rational and scientific polls and forecasts done by some of the research companies including Gallup Korea are commented that they have improved the quality of Korean election culture. In the article, we will look into the process of the election polls which have been done seven times for 15 years, and then deal with the meaning of the election polls.

This study aims to examine the relation between opinion perception and opinion expression by issue types by analyzing online poll results and respective bulletin boards. To find out how opinion poll results affect the public opinion perception cues and opinion expression through the internet, the study applied a method of content analysis to the online contents provided by Naver.com, one of the most popular portal sites in Korea. A total of four issue types, along with 2,250 messages were chosen for analysis. The study results revealed that internet users perceived opinion atmosphere through the poll results and expressed their opinions depending on the issue types. In case of an issue where majority views are manifested as online poll results, users tended to follow that majority views by retaining their initial opinion. Majority opinion by the poll results held a dominant position in bulletin board. The results partially support Noelle-Neuman(1994)'s spiral of silence theory in the context of computer-mediated communication contrary to the belief that anonymity in the cyberspace tends to encourage participation of minority opinion group. According to the findings, people when they perceive their opinion as that of minority are discouraged to express their views even when they are online.

The government and public institutions are conducting public-opinion surveys as means of drawing the scientific policy decisions throughout the country's whole sectors ; society, culture, welfare, education, etc. The Government Survey Data have been under management by each governmental department, but the improper ways of data collection and management have led to omissions and losses of some data. Also there are limitations on the statistic usage and access to the data due to the fact that the data are managed dispersedly in the form of printed materials. Accordingly, to make the survey data available for the long-term preservation and usage, this study suggests collection policy, standard of evaluation, metadata, the procedure and method of converting materials, preservation format.

Opinion polls have become a powerful means for election campaigns and one of the most important subjects in the media in that they predict the actual election results and influence people's voting behavior. However, the more active the polls, the more often they fail to properly reflect the voters' minds in measuring the effectiveness of election campaigns, such as repeatedly conducting polls on the likelihood of winning or support rather than verifying the pledges and policies of candidates. Even if the poor predictions of the election results of the polls have undermined the authority of the press, people cannot easily let go of their interest in polls because there is no clear alternative to answer the instinctive question of which candidate will ultimately win. In this regard, we attempt to retrospectively grasp public opinion on the 20th presidential election by applying the 'YouTube Analysis' function of Sometrend, which provides an environment for discovering insights through online big data. Through this study, it is confirmed that a result close to the actual public opinion (or opinion poll results) can be easily derived with simple YouTube data results, and a high-performance public opinion prediction model can be built.

세계를 놀라게 한 체르노빌원자력발전소 사고에도 불구하고 미국국민의 8할이 원자력을 지지하고 있음이 최근 실시한 여론조사의 결과에서 밝혀졌다. 이와같은 사실은 지난 5월 미국 캠브리지, 리포트사가 미국의 성인 1,500명을 대상으로 한 여론조사에서 응답자의 $78\%$가 원전 건설에 대해 강한 관심을 나타내는 것으로 밝혀졌다.

The purpose of this study is to evaluate the opinion survey data quality used in theses and to suggest the data quality evaluation model. We used 16 items which were suggested by KASR(Korean Association for Survey Research) as a standard of survey data quality evaluation in thesis. According to the result, the data quality used in the theses is very poor level not to be accepted. And we tried difference tests between two proportions in order to find there were significant differences among stochastical variables. The result showed that there were some significant differences in sampling error and number of analyzing method between doctor and master. we suggested a model that was weighted by 9 special items for a survey data quality evaluation in a thesis by observing them from KASR's principles.

Statistical models are proposed for analyzing categorical data in the presence of missing observations or nonresponses which might occur in the sampling surveys and polls. As an illustration, we analyzed real polling data of the pre-presidential election in the USA, 1948, It had been predicted that Dewey would win the election. However, Truman won in the actual election.

A method for poll analysis using information theory and data visualization is proposed in this paper. Questions of opinion poll consist of a target variable and many explanation variables. The type of explanation variables is either numerical or categorical. In this study, explanation variables of mixed types have been ranked according to the magnitude of their effect on target variable by using mutual information. Likewise, the order of explanation variables has been evaluated using data visualization. This is the first study to quantify the impact of specific explanation variable on the related target variable.
