The 2022 Presidential election is approaching. Because health policies are intimately connected to other policies and involve multiple stakeholders, it is difficult to promote policy changes. Hence, the presidential election, during which policymakers are replaced, is a great timing for making policy improvements. Several important policies have been introduced and promoted throughout the presidential election process. However, these policies have been implemented without going through sufficient discussion among the experts but rather through the voices of minority groups with stronger political will. This eventually posed an obstacle to the balanced development of the entire health care system. The current medical system faces challenges that need to be addressed in the medium and long term. In particular, we should be wary of the populistic approach. We look forward to seeing more policy commitments, proposed through the evidence-based policy process and sufficient amount of discussion among the experts.

The goal of this study is to propose the approaches to improve the voters' awareness by analyzing the voters' awareness on the fake news related to the elections and identifying the problems with the focus on the 19th Presidential Election. In accordance with the analysis on the data from 128 respondents (53 male and 75 female respondents), the 99.2% (127 respondents) of respondents had informations on elections mainly through broadcasting(77.2%), smart phone(70.9%), Internet(63.8%) and newspapers 32.3% which accounts for 41 respondents) in that sequence. Next, the 87.4% of respondents thought that the informations on elections had more impact on their voting than the generally expected degree. Meanwhile, the voters' awareness on the facts was analyzed by collecting and presenting the information on elections which stated by candidates in the 19th Presidential Election. In accordance with the analysis, there were the significant differences per age groups. The Scheffe test indicated that the respondents in 30s to 40s had significantly higher average awareness than those in 20s. According to the analysis results, it was proposed that the National Election Commission install the election information investigation and analysis committee in the election organization, investigate and analyze the election informations each election for providing real facts to the public, the voters.

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.

This article analyzes three major issues related to regional voting in South Korea. First, is regional voting a regional problem or an ideological problem? Second, is regional voting caused by regional identity or regional interest? Third, has regionalism waxed or waned? Analyses of the cumulative data set since the 15th presidential election yield the following results. First, Yongnam people are more conservative than Honam people. Second, regional voting consists of ideological and regional components. Third, there exist both a hometown effect and an abode effect in regional voting, but the latter is significantly greater than the former. Forth, regionalism had weakened between the 15th National Assembly election and the 16th Presidential election, but has not varied much since then.

On December 9, 2016, the decision of impeachment of the National Assembly decided against Park Geun-hye came from the nomination conflicts of the 20th general election between Pro-Park group and Anti-Park group at the ruling Saenuri Party. Therefore, this study focused on the nomination conflicts of the ruling party and the opposition party on the election results in the 20th general election on the public sentiment of the people. The nomination conflicts of the ruling and opposite parties were a prelude to the victory of the 19th presidential election, and it was serious faction conflict. Firstly, the study examined how the nomination conflicts of each party were centered on President Park Geun-hye as well as the leaders of each party and the chairman of the nomination committee. Secondly, the study examined what kind of changes would be made to the composition of presidential candidates for each party at the time of the presidential election. Thirdly, the study examined the opposition parties' separation between the Minjoo Party of Korea and the People's Party of Korea before and after the election and the issue of initiative in Honam. As a result of the analysis, the 20th general election failed to obtain a majority seat of the ruling Saenuri Party, and the opposition won and formed the majority. The reason why President Park and Saenuri were greatly defeated in the contest even in the situation where the opposition parties were divided is the root cause in the attitude of Pro-Park group and Anti-Park group who assumed their victory. Therefore, it is highly possible to render its responsibility to President Park Geun-hye, who has become a 'past power', and it has opened up the possibility that the emergence of future power by opposition parties. In the case of the opposition party, it is clear that the battle for Honam, which is a traditional opposition party's support group, is a matter of good fortune of the two major powers, Moon Jae In and Ahn Cheol Soo.

There will be coming soon a sequence of the so-called election season in Korea. That is the 20th session of general elections and the 19th presidential election which are taking place one after another. When we talk about presidential candidate, we may realize that the choice were relied upon candidate's facial appearance and speech, voice, dress, and so on. One poll showed that capacity and policy were ranked high and figure and image were ranked next by asking "what is the most important factor when you vote for the president?" This study looked into the candidate's face of a newly elected public office through the election voting. I studied how the factors of sex and beauty may affect on the election results. I analyse survey of candidate's photo on the election leaflets. Analyzed result said that candidate's competency and trust have strong relations in the voting choice rather than beauty even if it is statistically significant. I also find that both beauty and competency are positively interrelated.

This study is based on the screen composition(shot size, split screen, candidate placement, lighting, stage) that fits the discussion process (round table, sitting, standing method) adopted from the 19th presidential candidates' TV joint discussion to analyze the adequacy and limitations of the methodology(design, candidate background, etc.). In addition, the progress and screen composition of the 45th US Presidential Candidates Debate in 2016 and the 25th Presidential Candidates of France TV Joint Debate in 2017 have been analyzed to compare and contrast the methods used in Korea. Through this, we apply the screening method to the 20th Presidential Candidate TV Joint Debate, which will be held in 2022, to fit the fixed discussion process that can fully identify candidates' qualities, policies, and vision.

There are three focuses in the paper. Firstly, the study identified what channels were most viewed by YouTube users to watch the 'Daejang-dong scandal,' which was the most powerful agenda to influence the candidate preference among voters during the 20th presidential election. Secondly, the study analyzed whether the political tone of the first videos was in line with that of the subsequent videos. Finally, we compared the sentiment of comments on the first and subsequent videos. The results showed that TBS 'News Factory' and 'TV Chosun News' represented liberal and conservative factions, respectively. Secondly, the political tone of channels that were viewed subsequently was neutral, but the conservative channel users left more negative comments and that was significant statistically. In addition, about 80% of the conservative and liberal channel users shared the same political tendency with the channel they watched first, and more than 90% of the comments left at the subsequent videos in line with that of at the first news. Based on these results, the study concluded that the voters tended to seek political news that was similar with their political ideology, and it was considered a sort of echo chamber phenomenon on the YouTube. The study suggests that the performance of high-quality journalism by traditional news outlet might contribute to decrease the negative influence of political contents on YouTube users.

In this paper, we propose a procedure to build a prediction interval of the sum of dependent binary random variables over a graph to account for the dependence among binary variables. Our main interest is to find a prediction interval of the weighted sum of dependent binary random variables indexed by a graph. This problem is motivated by the prediction problem of various elections including Korean National Assembly and US presidential election. Traditional and popular approaches to construct the prediction interval of the seats won by major parties are normal approximation by the CLT and Monte Carlo method by generating many independent Bernoulli random variables assuming that those binary random variables are independent and the success probabilities are known constants. However, in practice, the survey results (also the exit polls) on the election are random and hardly independent to each other. They are more often spatially correlated random variables. To take this into account, we suggest a spatial auto-regressive (AR) model for the surveyed success probabilities, and propose a residual based bootstrap procedure to construct the prediction interval of the sum of the binary outcomes. Finally, we apply the procedure to building the prediction intervals of the number of legislative seats won by each party from the exit poll data in the $19^{th}$ and $20^{th}$ Korea National Assembly elections.

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.
