OpenDaylight is an SDN (Software Defined Networking) open source framework, which is popular in network fields recently. This paper analyzes the performance of a controller cluster architecture by focusing on distributed datastore and Raft leader election algorithm. In addition, we propose an enhanced version of Raft algorithm in order to improve the performance of distributed datastore by distributing shard leaders over controller cluster. This paper compares the conventional Raft algorithm with the proposed version of the Raft algorithm. Moreover, we compare the performance of distributed datastore according to shard roles such as leader and follower. Experimental results show that Shard leaders provide better performance than followers and Shard updating requests need to be distributed over multiple controllers. So, by using proposed version of Raft algorithm, controller performance can be improved. The details of the experiment results are cleary described.

This paper investigates how news media frame news editorials to deliver their subjective ideological stance through news discourse related with two candidates in 2016 U.S presidential election. For this purpose, 13 editorials were chosen and analyzed which appeared on the New York Time for the period from Sept. 1 to Sept. 30, almost two months prior to the election, giving special attention to the headlines of those editorials and the expressive linguistic forms in the selected two articles, based on the two theoretical frameworks-van Dijk' (1996)'s ideological square and Martin and White (2005)'s Appraisal Theory. The results are as follows: (1) editorials clearly supported Hillary Clinton; (2) following the appraisal theory, the category of 'feeling' was applied in expressing the preference for Hillary, whereas the strategy of judgment for Trump, where the strategy of 'emphasis' from the ideological framework were used for both candidates.

The purpose of this study was to analyze whether the promises of library field were, what the promises of candidates were, and whether the content of the promises showed the dissimilar tendency or discrepancy. The starting point of this study was that the library-related issues should be raised in the local election in order that library-related problems in the local area were considered as the policy. The standpoint of this research was based on the notion the library-related problems could be settled if the candidates have an interest in the library field. The range of this research was limited in the election conducted in June 2. 2010. Candidates' promises were collected through a questionnaire, categorized and analyzed by subject. According to the result of analysis, the most candidates had interest in establishing of library infrastructure, on the other hand they had no interest in collection development, library policy, allocation of budget, and job creation for librarian.

This paper is designed to search the new alternatives to supplement the inconvenience of the traditional written ballot method which is executed every early semester to select the class board at the school. It is prepared on the based the results of the design and implement of the wired/wireless inter-working mobile electronic voting system where the students can participate in the real-time class board selection and the decision-making utilizing the mobile phones, PDA and PC they commonly have. It is time when we should consider introducing the electronic voting system, to minimize the students' inconvenience and the subsequent missing class, having to wait in the long line in the designated place to select the class board at every election season. This system enables the students to participate wherever they are other than the common place as well. Further, this research will provide the opportunity to think over the new school election culture in line with the age of Ubiquitous, as well as the useful means in the field to promote the active participation of the parents and students in the students' self-administration, decision-making necessary at the schools.

This study empirically analyzes whether political rent-seeking behavior exits in Korea. The empirical analysis shows that there is a cyclical decline in aggregate revenue immediately following the election year. However, when using other aggregate fiscal variables including aggregate revenue, fiscal balance, tax and public burden ratio, no such cyclical deterioration are found. By sector, the expenditures of the economic affairs show a cyclical increase in the year right after the election. In addition, as the ratio of ruling party senators to total senators is high, the expenditures of the economic affairs tend to increase more and this tendency becomes more stronger right after the presidential election year. Such a result turns out to be consistent even when the expenditure was analyzed separately from the mandatory and discretionary expenditures by sector. This is a testimony to the existence of political rent-seeking behavior in Korea.

It was the 18th presidential election TV debate Twitter participation of SNS. Began to diverge as the era of social media, combined with SNS through in the mass media, media web 2.0. Search tweets, retweets, while the formation of policy issues, the agenda of Twitter users to listen to the statements of the candidates using the Internet or a smartphone. The highest number of tweets immediately issue statements were made. Content during the progressive tweets core keywords you do not often discussed, followed by the negative information increases the number of tweets has become a policy issue. Top retweets was to evaluate the process of debate, regardless of the issue. Tweeter complements the TV so Twitter has made public opinion. Smart phones and SNS Twitter, combined with the TV and the participation and direct democracy, voters vote one instrument was realized. Should forward approval ratings, real-time Twitter subtitles on the TV screen in TV debate Twitter influence in the election will be greatly expanded.

We examined the relationship between the order of signs and the order of vote within parties in electing local district councilors during the 7th nationwide local election held on June 13th, 2018. We analyzed election data for respective cases that include two, three, four candidates within the same party. In most cases, the candidate with sign 'Ga' gained more than other candidates in the same party, showing a need for provisional measures. In addition, a difference in voting tendency was found between in-house voting and early outside voting when there were two candidates in the Democratic Party of Korea as well as for when there were two candidates in the Liberty Korea Party.

The March 2022 presidential election held at the peak of the COVID-19 pandemic drew flak for undermining the principle of universal suffrage by failing to guarantee properly the voting rights of confirmed and quarantined persons. Guaranteeing their voting rights requires thinking about e-voting that can fundamentally overcome the temporal and spatial limitations of current paper voting polling stations. The question is how to deal with the increased possibility of contradicting or violating the principles of equality and direct and secret suffrage due to the expansion of universal suffrage. In order to obtain implications for this, we looked at the case of Estonia, which has been holding 11 national elections without any problems since the introduction of e-voting in 2005. Estonia was successfully building trust in the system, government, and society through the institutionalization and routinization of the overall socio-technical system of e-voting, along with political and constitutional agreements on the principles of elections. Therefore, we should not only consider the possibility of e-voting in terms of technological development and level but also discuss the establishment of trust by mediating conflicts between election principles from a normative point of view to reach a social consensus.

In WSNs, a clustering algorithm groups sensor nodes on a unit called cluster and periodically selects a cluster head (CH) that acts as a communication relay on behalf of nodes in each cluster for the purpose of energy conservation and relay efficiency. Meanwhile, attack techniques also have emerged to intervene in the CH election process through compromised nodes (inside attackers) and have a fatal impact on network operation. However, existing countermeasures such as encryption key-based methods against outside attackers have a limitation to defend against such inside attackers. Therefore, we propose a statistical detection method that detects abnormal CH election behaviors occurs in a WSN cluster. We design two attack methods (Selfish and Greedy attacks) and our proposed defense method in WSNs with two clustering algorithms and conduct experiments to validate our proposed defense method works well against those attacks.
