지방정부 구성을 위한 한국의 지방선거에서는 종종 개별 지역에 따라 특화된 선거쟁점보다는 대통령을 둘러싼 중앙정부의 정치적인 쟁점이 선거결과에 더욱 중요한 영향을 띠어왔다. 본 연구는 2018년 지방선거를 대통령의 국정운영을 평가하는 선거로서 인식하는 유권자가 누구인지를 규명한 뒤, 지방선거를 중앙정부에 대한 견제와 평가로 보는 인식 및 대통령의 국정운영에 대한 유권자의 평가가 투표행태에 미치는 영향을 분석한다. 본 연구의 경험적 분석에 따르면, 문재인 대통령의 국정운영에 대하여 긍정적으로 인식하거나 이념적으로 중도층 또는 자유한국당을 극단적으로 좋아하거나 싫어하지 않는 유권자의 경우에 지방선거를 대통령에 대한 중간평가로 인식하는 경향이 있었다. 본 연구는 인지적 효율성을 추구하는 유권자들은 지방선거를 대통령의 국정운영을 평가하는 선거로서 인식하고 있으며, 대통령의 국정운영을 긍정적으로 인식할수록 집권여당의 후보 역시 긍정적으로 평가하고 있음을 보여준다. 지방선거는 지방자치의 핵심적인 제도이지만 지방선거에서 나타나는 중앙정치의 강한 영향은 지방자치의 독자성 및 자율성을 침해하는 문제가 될 수 있다는 점에서 지방선거 제도 및 운영에 시사하는 바가 크다고 할 수 있다.

Electronic voting machines (EVMs) are replacing research ballots due to the errors involved in the manual counting process and the lengthy time required to count the votes. Even though these digital recording electronic systems are advancements, they are vulnerable to tampering and electoral fraud. The suspected vulnerabilities in EVMs are the possibility of tampering with the EVM's memory chip or replacing it with a fake one, their simplicity, which allows them to be tampered with without requiring much skill, and the possibility of double voting. The vote data is shared among all network devices, and peer-to-peer verification is performed to ensure the vote data's authenticity. To successfully tamper with the system, all of the data stored in the nodes must be changed. This improves the proposed system's efficiency and dependability. Elections and voting are fundamental components of a democratic system. Various attempts have been made to make modern elections more flexible by utilizing digital technologies. The fundamental characteristics of free and fair elections are intractability, immutability, transparency, and the privacy of the actors involved. This corresponds to a few of the many characteristics of blockchain-like decentralized ownership, such as chain immutability, anonymity, and distributed ledger. This working research attempts to conduct a comparative analysis of various blockchain technologies in development and propose a 'Blockchain-based Electronic Voting System' solution by weighing these technologies based on the need for the proposed solution. The primary goal of this research is to present a robust blockchain-based election mechanism that is not only reliable but also adaptable to current needs.

본 연구는 6.2지방선거를 대상으로 선거에서 드러난 투표행위를 분석하고 후보자 인지 및 선택에 미치는 요인을 탐색, 비교하여 시사점을 얻고자 한 것이다. 이를 위해 이번 선거에서 투표를 한 유권자들을 중심으로 심층인터뷰를 실시하였다. 분석결과 대부분의 응답자들은 자신의 정치이념 성향을 중도로 보고 있으며, 투표할 후보자 결정은 투표 2-3일전에 가장 많이 하는 것으로 나타났다. 또한 후보자 투표 결정 동기는 소속정당이 가장 높은 것으로 나타났으며, 투표행위는 대체로 소신투표를 하는 것으로 나타났다. 그리고 여론조사 결과는 후보자 선택에 영향을 주지 않는 것으로 나타났으며, 여론조사가 실제 투표 결과와 차이가 많이 난 것은 여론조사 방법이 잘못되었고, 자신의 의견을 숨기려는 의도에서 비롯되었다는 것을 알 수 있었다. 또한 후보자의 이미지에 영향을 주는 것은 언론매체이지만 후보자의 정책을 인지한 채널은 선거홍보물로 나타났다. 아울러 투표에 가장 큰 영향을 미치는 것은 경제 및 정치쟁점이었고, 특별히 이번 6.2 지방선거에서는 4대강 쟁점이 가장 높은 것으로 나타났다. 이러한 연구결과는 유권자들의 투표행위를 구체적으로 심도 있게 파악한 것으로 앞으로의 선거에서 여러 가지로 활용할 수 있는 시사점을 제시하고 있다.

There have been many studies that applied a data-driven analysis method to social media data, and some have even argued that this method can replace traditional polls. However, some other studies show contradictory results. There seems to be no consensus as to the methodology of data collection and analysis. But as social media-based election research continues and the data collection and analysis methodology keep developing, we need to review the key points of the controversy and to identify ways to go forward. Although some previous studies have reviewed the strengths and weaknesses of the social media-based election studies, they focused on predictive performance and did not adequately address other studies that utilized social media to address other issues related with public opinion during elections, such as public agenda or information diffusion. This paper tries to find out what information we can get by utilizing social media data and what limitations social media data has. Also, we review the various attempts to overcome these limitations. Finally, we suggest how we can best utilize social media data in understanding public opinion during elections.

본 연구에서는 선거여론조사에서 좀더 많은 젊은 유권자를 접촉하기 위해서 인터넷조사의 적용 가능성을 제시하고자 한다. 2007년 대선여론조사에서 수집한 인구통계학 변수와 공변량 변수를 이용하여 성향점수모형을 추정하였다. 인터넷조사에서 투표성향을 전화조사의 것과 같이 보정하기 위해서 추정한 성향점수모형을 사용하였다. 실제로 인터넷조사 데이터에 성향점수 가중치를 적용함으로써 전화조사의 추정치에 근접하게 됨을 보였다. 성향가중모형을 인터넷조사의 데이터에 적용하여 인터넷조사데이터만으로 전화조사와 유사한 추정치를 얻을 수 있음을 예시함으로써 선거여론조사에서 전화조사의 대안적인 조사방법으로 인터넷조사의 활용가능성을 실제 조사데이터로 입증하였다는 데 그 의의가 있다.

Mobile voting can reduce the costs spent in elections, and it can encourage people to participate in the elections more actively because it allows them to vote anytime at anywhere. The trial of mobile voting in 2012 by Democratic United Party in Korea, showed the possibilities of mobile democracy but it also showed very critical problems such as illegal voting by proxy, source code open, open to nationwide for local parliamentary candidate ballot, privacy and hacking. In this paper, we analyze the result of the mobile ballot trial, and introduce the problems that has been revealed. After that we propose some system requirements for the new mobile voting system to prevent the problems according to the stages of voting: system development, voting stage, and counting and validating stage. At each stage, there are several requirements to be met for reliable mobile voting. Our research contribute to mobile democracy and implementation of mobile voting systems in that we analyzed the real case and raised issues for the real problems.

The detection of human behavior from social media revolutionized health, business, criminal and political prediction. Significance of it, in incentive transformation of public opinion had already proven for developed countries in improving democratic process of elections. In $3^{rd}$ World countries, voters poll votes for personal interests being unaware of party manifesto or national interest. These issues can be addressed by social media, resulting as ongoing process of improvement for presently adopted electoral procedures. On the optimistic side, people of such countries applied social media to garner support and campaign for political parties in General Elections. Political leaders, parties, and people empowered themselves with social media, in disseminating party's agenda and advocacy of party's ideology on social media without much campaigning cost. To study effectiveness of social media inferred from individual's political behavior, large scale analysis, sentiment detection & tweet classification was done in order to classify, predict and forecast election results. The experimental results depicts that social media content can be used as an effective indicator for capturing political behaviors of different parties positive, negative and neutral behavior of the party followers as well as party campaign impact can be predicted from the analysis.

Purpose: This paper estimates the impact of the epidemic crisis on election outcomes through investigating the effect of Covid19 crisis on election results of 21st General Election held in April 15th 2020 in Korea. Research design, data and methodology: This study employs Ordinary Least Square (OLS) method using district-level data from Seoul and Gyeonggi province available at National election data in Korea. Results: Despite the current crisis in Korea, Covid-19 has had positive effects on voter turnout on average, after controlling for other factors. On the other hand, the effect of Covid-19 on the voter turnout was negative in districts with a larger aging population and higher health insurance premiums. In addition, Covid-19 negatively impacted vote shares for the incumbent party, while its rival party saw gains in their votes. Conclusion: The effect of Covid-19 election outcomes in Korea is distinct from other countries due to the nationwide acknowledgment of the Korean government's achievement in managing the epidemic. This implies that the crisis management ability of a government is crucial in gaining support for an incumbent party in future elections. Countries facing upcoming elections need to implement acceptable Covid-19 restriction policies as well as economic support for compensation to reap similar benefits.

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.

캄보디아의 2017년은 격동의 한 해였다. 6월에 치러진 지방선거는 처음으로 부정선거 시비가 사라진 모범적인 선거였다. 집권당인 캄보디아인민당은 과반의 지지를 획득했음에도 불구하고 선거결과에 만족하지 않고 정당법 개정을 통해 야당인 캄보디아구국당을 해산했다. 캄보디아구국당 대표는 반역 혐의로 구속되었고 정부에 비판적인 신문사와 방송국이 무더기로 폐쇄되었다. 표현의 자유를 박탈당한 시민사회는 고도의 감시와 사찰 속에 극도로 위축되었다. 캄보디아의 민주주의 붕괴에 대한 외부의 우려와 경고에 대해 캄보디아 정부는 중국의 지원을 등에 업고 정면으로 맞서고 있다. 정치적 격변 속에서도 캄보디아 경제는 꾸준히 고도의 성장률을 유지했지만 외형적 성장 이면의 구조적 취약점은 지속가능성을 위협하고 있다.
