It is very important to obtain objective and credible information through election polls in order to contribute to the correct voting behavior of the voters or to establish appropriate election strategies for candidates or political parties. Therefore, many related organizations such as political parties, media organizations, and research institutions have been making efforts to improve the accuracy of the results of the polls and the election prediction. Kim et al. (2017) analyzed whether the non-response group responded that there is no support candidate in the election survey to increase the accuracy of the estimation of the vote rate. As a result, it has been confirmed that the accuracy of the estimation of the vote rate can be significantly improved by performing an appropriate classification on the non-response layer. In this study, we propose a method to estimate the turnout by each strata (sex, age group) under the condition that the total turnout rate is given for a specific district (region) and propose a procedure to predict the vote rate by reflecting the turnout. In addition, case studies were conducted using data gathered through telephone interviews for the 20th National Assembly elections in 2016.

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.

Social network services (SNS) have become the most common tool for the communication of public and private opinions as well as public issues; consequently, one may form or drive public opinions to advocate by spreading positive content using SNS. Controversy for survey data based opinion poll accuracy continues in relation to response rate or sampling methodology. This study suggests complementary measures that additionally consider the sentiment analysis results of unstructured data on a social network by data crawling and sentiment dictionary adjustment process. The suggested method shows the improvement of prediction accuracy by decreasing error rates.

The purpose of this paper is to start off a debate in the current situation in which there exists two different logics about a newspaper company expanding their business field to the broadcasting market. In order to analyze the implications of the phenomenon, three points are raised and analyzed. First, Chosun-Ilbo, Jungang-Ilbo and Donga-Ilbo, who had a permission to get into the broadcasting arena, did not make their logic based on the fact while deriving the public opinion to be optimistic. Second, they strictly held their frames in order to support their logics which were an overall deregulation, to stimulate the economy and to create jobs without introducing various perspectives. Third, broadcasting of three major newspaper companies could monopolize the public sphere rather than contributing to the diversity of public opinions against three existing broadcasting companies KBS, MBC, SBS.

55.9%, 우리나라의 최근 전력소비증가율(2002~2010년)이다. 경제협력기구(OECD) 평균인 9.1%의 5배에 해당하는 수치이다. 원가 이하인 현재의 전기요금체계와 이로 인해 사회에 만연된 전력과소비, 이에 더해 일부 지자체 및 환경단체 민원 등에 따른 발전공급력 건설 지연, 효율적 에너지 소비행태의 미 정착 등은 수년 간 전력수급에 밝혀진 적신호를 좀처럼 바꾸지 못하고 있다. 이에, 전기협회는 대국민 의식실태조사를 통해 최근의 전력수급상황을 바라보는 국민들의 인식과 정서를 파악하고, 국민들이 원하는 전력수급안정화 지표를 추출하여 정책 참고자료로 제공하는 한편, 낭비요인 없는 효율적인 전력소비의 확산 등 안정적인 전력수급정책에 기여하기 위해 대국민 여론조사(15개 광역시 20세 이상 성인남녀 1000명)를 시행했다.

This study suggests the applicability of web surveys regarding elections in order to contact a great number of young people. The propensity weighting model was estimated using the demographic variables and the covariate variables collected during the 2007 presidential election surveys. In order to adjust the internet survey to the telephone survey, we used the propensity score method. Propensity score weighting made the internet survey results closer to the telephone survey results. This shows that an internet survey with propensity weighting model is a potential alternative survey method in the prediction of elections.
