Researchers in sample surveys have long recognized that what people say they are going to and what they do are not always the same, to say the least. Naturally this inconsistency distorts the survey results, especially in election poll surveys in Korea. How can one cope with this measurement bias\ulcorner This paper suggests two ideas: election poll tree and using posterior probability. By using two ideas the inconsistency of the poll survey results could be improved much or less.

We calculated the predictive interval for the number of seats belonging to major political parties in the case of the 2004 General Election of Korea, using Bayesian frame of inference. Moreover, we proposed the adjustment procedure for correcting the minor group's propensity of refusal or nonresponse due to effect of the spiral of silence.

It is important to efficiently elect the cluster header in Hierarchical Sensor Network, because it largely affects on the lifetime of the network. Therefore, recent research is focused on the lifetime extension of the whole network for efficient cluster header election. In this paper, we propose the new Cluster Header Election Scheme in which the cluster is divided into Group considering Distance from Upper Node, and a cluster header will be elected by node density of the Group. Also, we evaluate the performance of this scheme, and show that this proposed scheme improves network lifetime in Zigbee environment.

Assuming that a political party has a strong incentive to gain votes via issue setting as part of its campaign strategy, this study utilized a Web experimental survey to explore the extent to which three issue-related campaign advertising strategies - namely, issue ownership, issue convergence, and issue trespassing - affected voters' perceptions toward parties' issue-handling capabilities. Our empirical results show that issue ownership perceptions exist in Taiwan. In the 2012 Taiwan presidential election, as issue ownership advertisements may reinforce voters' beliefs regarding parties' issue-handling capabilities, issue trespassing advertising may improve a party's image on the disadvantageous issue dimension. At least our data shows that the Kuomintang's (KMT) advertisements have both effects.

In clustered sensor networks, since a CH (Cluster Head) collects data from its members and delivers the collected data to the sink, it is very important to prevent compromised nodes from joining a CH election and manipulating and fabricating the election result. In order to protect CH elections from compromised nodes, unpredictability, non-manipulability, and agreement property should be guaranteed in CH elections. However, existing CH election schemes cannot prevent intelligent compromised nodes from skilfully violating those properties via their cooperation. In this paper, we propose a scheme which protects the CH election process by detecting intelligent compromised nodes and excluding them. For every CH election round, each member gives a direct trust value to other members according to their behavior. Then a real reputation value is given to each member by combining the direct trust value and indirect trust values provided by other members. Then, each node evaluates the real reputation values of members in its cluster and excludes some untrustable nodes from CH candidates. The scheme greatly improves the non-manipulability and agreement property of CH election results compared to other rival schemes. Furthermore, the scheme preserves the high non-manipulability and the high agreement property even in an environment where message losses can happen.

The purpose of this study is to understand the utility of election campaign advertising by applying Q methodology that draw upon schematic model in subjectivity study. A survey was carried out among college students to classify the 16 selected Q-statements into a normal distribution using a 7 point scale. The collected data was analyzed using QUANL program, and principal component analysis using varimax rotation was used to identify the types of perceived utility of election campaign advertising. Type I can be categorized by a strong concern for the advertising technique improvement, Type II can be categorized by advocating for interest induction and Type III can be categorized by the truth inducement. The use of Q methodology provides insights into audience perceptions on the utility of election campaign advertising that would not be available through traditional methodologies and offers a foundation for audience involvement to address and overcome concerns about the utility of advertising for election campaign.

This study examined the trends and issues of social media campaign studies from three aspects-campaign strategy, institutional environment regulating the social media, and political effect. Then, this study performed an empirical analysis on the case of the 20th general election in order to discuss the political effect, which has been analyzed the least. Specifically, this study empirically examined the trends of candidates' participation in the twitter campaign, the partial mobilization and voter response, and the platform effect on the election results. The study examined all of the candidates' twitter accounts and traffic and found the following results.-first, the number of participants in the twitter campaign increased significantly compared to the 19th general election, and the campaign was dominated by only two political parties that had more power to mobilize resources; second, it was clearly identified that twitter is a partisan media. where specifically, those in the mainstream of the Democratic Party mobilized much more supporters; and lastly, the twitter campaign has a positive impact on the increase in the rate of votes and chances of winning the election. Particularly, the number of followers and the duration of activities were found statistically meaningful, proving that promotion of networking and social capital is more important in election campaigns.

The new president was elected unusually within short period, because of the president's impeachment. As the result, policy window as the president's election was rarely opened in healthcare sector. The new government has to overcome the era of aged society, low birth rate, and low economic growth rate and to prepare the unification of nation. The new government should set the priority of healthcare policies through a holistic and systematic approach. And the new government must implement a balanced healthcare policy with equity and efficiency, regulation and support, consumers and suppliers, in-kind benefits and cash benefits, and so on.

A large literature identifies perceptual differences between citizens that support winning parties versus losing parties. These analyses fail to capture the complexity of mixed member legislative systems where one can be a winner or loser at both the national and district level. This paper proposes a two-level framework for the analysis of mixed system. An analysis of Taiwan’s first election under a mixed system provides evidence that both support for a national winner and district level winner produce boosts in positive perceptions of the electoral system. National success appears to be a larger motivator of perceptions.
