Based on the theory of news media's agenda-setting function, this study analyzed Korean public's most important problems (MIP) and the degree of public consensus on the importance of those MIP's. The analysis was done in terms of both time and social strata. According to the findings, economy, social welfare, and political issues were in the for tier of the MIP list. The analysis of issue diversity (H-statistic) also demonstrated a relatively high degree of agenda consensus among Korean public despite some fluctuation in the consensus level, which appears to be higher than that among the American public. A decrease in the degree of agenda consensus with the passage of time appealed to be a general phenomenon across diverse social strata. However, the degrees of consensus-building were different in light of education, socioeconomic status, and the size of residential area. Those who are more educated, have more economic power, and live in a larger city had more chances to experience agenda consensus. These results seem to be basically attributable to the presumed positive relationship between these demographic variables and media exposure. The different degrees of public consensus according to the different levels of those demographic variables suggest that a closer investigation into the various influences on the importance of public issues among the respondents should be done in future studies.

The study's goal is to look at the factors that influence people's willingness to whistleblow in the Malaysian public sector by applying two elements from the Moral Intensity Theory: the magnitude of consequences and societal consensus with professional commitment as an additional variable. The cross-sectional study used primary data collection through questionnaires adopted from previous studies. The survey questionnaires were distributed to target respondents from 27 ministries in Malaysian public sectors selected based on their grade positions in the departments ranging from Grade 29 and above. The findings revealed that societal consensus and professional commitments significantly impact the intention to whistleblow. The findings imply that closed people's opinions may have certain persuasive elements that influence the act of whistleblowing as a moral and ethical activity, thereby increasing their whistleblowing intention. The results also suggest that when individuals are more committed to their career and organization, they will act ethically and under the professional norm, hence, they will be inclined to whistleblow. On the other hand, the magnitude of consequences suggested an insignificant relationship with the intention to whistleblow. The results could facilitate the government in curbing the whistleblowing issue by defining its root before the implementation of necessary policies.

Recently, blockchain technology has been recognized as one of the most important issues for the 4th Industrial Revolution which can be represented by Artificial Intelligence and Internet of Things. Cryptocurrency, named Bitcoin, was the first successful implementation of blockchain, and it triggered the emergence of various cryptocurrencies. In addition, blockchain technology has been applied to various applications such as finance, healthcare, manufacturing, logistics as well as public services. Distributed consensus algorithm is an essential component in blockchain, and it enables all nodes belonging to blockchain network to make an agreement, which means all nodes have the same information. For example, Bitcoin uses a consensus algorithm called Proof-of-Work (PoW) that gives possession of block generation based on the computational volume committed by nodes. However, energy consumption for block generation in PoW has drastically increased due to the growth of computational performance to prove the possession of block. Although many other distributed consensus algorithms including Proof-of-Stake are suggested, they have their own advantages and limitations, and new research works should be proposed to overcome these limitations. For doing this, above all things, we need to establish an evaluation method existing distributed consensus algorithms. Based on this motivation, in this work, we suggest and analyze assessment items by classifying them as efficiency and safety perspectives for investigating existing distributed consensus algorithms. Furthermore, we suggest new assessment criteria and their implementation methods, which can be used for a baseline for improving performance of existing distributed consensus algorithms and designing new consensus algorithm in future.

This paper investigates how public opinion has affected the United States Senate's votes on arms control treaties. Applying multilevel modeling with post-stratification to national polls, this paper produces estimates of state-level opinion on both the New Strategic Arms Reduction Treaty of 2010 and the Comprehensive Test Ban Treaty of 1999. Using these estimate, this paper examines the relationship between public opinion and the Senate's votes on the treaties. This paper finds that the influence of public opinion was mostly significant but indirect. These findings indicate that some version of the delegate model of representation is more applicable to foreign policy making in Congress.

The advancement of information technologies including the Internet has affected the way of social information processing as well as brought about the paradigm shift to the information society. Accordingly, it is very important to study the process of social information processing over the digital media through which social information is generated, distributed, and led to social consensus. In this study, we analyze the mechanism of social information processing, identify a process model of social consensus and institutionalization of the results, and finally propose a set of information processing characteristics on the internet media. We deploy the ethnographic approach to analyze the meaning of group behavior in the context of society to analyze two major events which happened in Korean society. The formation process of social consensus is found to consist of 5 steps: suggestion of social issues, selective reflection on public opinion, acceptance of the issues and diffusion, social consensus, and institutionalization and feedback. The key characteristics of information processing in the Internet is grouped into proactive response to an event, the changes in the role of opinion leader, the flexibility of proposal and analysis, greater scalability, relevance to consensus making, institutionalization and interaction. This study contributes to the literature by proposing a process model of social information processing which can be used as the basis for analyzing the social consensus making process from the social network perspective. In addition, this study suggests a new perspective where the utility of the Internet media can be understood from the social information processing so that other disciplines including politics, communications, and management can improve the decision making performance in utilizing the Internet media.

Through an empirical comparative analysis, we found that people in mainland China and Taiwan demonstrate strong similarities in their support for democracy, based on democratic suitability, efficiency, preference, and priority. There are also differences in beliefs about democratic values. Compared to people in mainland China, the Taiwanese have a deeper and more widely shared belief in the principles of participation and pluralism, while the differences between their beliefs in the principles of equality, freedom, and checks and balances are narrow. Furthermore, people in mainland China and Taiwan have a strong similarity in their understanding of democracy, that is, they all present a mixed democratic understanding based on substantive bias. Overall, although the differences between mainland China and Taiwan's democratic practices are reflected in the level of value identification from the perspective of democratic support and democratic understanding, the popular democratic political culture in mainland China and Taiwan still has a relatively broad consensus. Thus, the integration and development of cross-strait relations not only has an increasingly profound social and economic foundation but also considerable consensus and mass support on the political and cultural level.

Researchers indicates several issues as to performance evaluation methods for public health centers. Firstly, health centers are passively involved in the evaluation process, the performance indicators are activity-oriented, and mostly unrealistic. Balanced Scorecard is one of the methods for evaluating organizational performance, which is utilized at current in many industries including public sector. The purposes of this study is to apply balanced scorecard approach to a public health center and to develop performance indicators as well as their vision and strategies. For developing performance indicators, researchers selected K City Public Health Center and implemented brainstorming with members of health promotion team. Through team process they suggested goals, strategies and several indicators they considered proper to accomplish their shared vision. And then appropriateness of the indicators were evaluated by professional researchers in health promotion field for consensus building by email questionnaire. Based on survey and professional consensus meeting, 11 performance indicators were tailored in four perspectives as well as 6 strategies and 10 strategic goals, which are steps for accomplishing shared vision of health promotion team. For details, refer to the paper. Most members of health promotion team were satisfied with the indicators. However issues such as low level of recognition and familiarity with a new concept of BSC, and cultural resistance to strategic approach in public organizations should be addressed for future application and dissemination of BSC technique to public health organizations.

Recently there have been increasing attempts to apply blockchains to businesses and public institutions. Blockchain is a distributed shared ledger with excellent transparency and security of data and through consensus algorithm, the same data can be shared to all nodes in order. In this paper, Modified PBFT which does not modify the PBFT consensus algorithm is proposed. MPBFT is able to tolerate Byzantine faults on a private blockchain on an asynchronous network. Even with the increase of participating nodes, the network communication cost can be effectively maintained. Modified PBFT takes into account the characteristics of an asynchronous network environment where node-to-node trust is guaranteed. In response to the client's request, PBFT performed the entire participation broadcast several times, but Modified PBFT enabled consensus and authentication through the 2 / N leader. By applying the Modified PBFT consensus algorithm, the broadcast process can be simplified to maintain the minimum number of nodes for consensus and to efficiently manage network communication costs.

This article addresses the 2nd Korean consensus conference on cloning that was held by the Korean National commission for UNESCO in 1999. Though previous perspectives recognized the conference as a new citizen's participatory institution. they do not consider that it contains the ideal of deliberative democracy. This article notes that the citizens participated directly and handled the important social agenda through debate in the consensus conference. The consensus conference is another democratic form derived from preference aggregating democracy in the sense that it basically depends on public judgement of the citizens. This consensus conference has the historical meaning because it is in fact the first experiment of deliberative democracy in Korea. 1) We examine the theoretical foundations of consensus conference. They are social constructionism of science, the tradition of societal debate, and deliberative democracy. 2) We explore what deliberative democracy is. It is different from aggregating preference democracy in the sense that it depends on public judgement rather than private preferences. 3) We investigate the features and meaning of deliberative democracy which has experiment on the conference. In the Consensus Conference it was observed that citizens changed their preferences and went forward to developing their view of community as a result of the process of deliberation. It can be said to confirm the significance of deliberative democracy. However, it is simultaneously an opportunity to clarify some problems of deliberative democracy. First of all, it shows that there were hierarchies within the citizens' panel as well as between the citizens' and the specialists' panels. Secondly, there are difficulties in expressing the value of life in argument or discourse. Also, we need the institutional efforts concerning future generations and nonhuman beings in the respect that cloning relates to them.

The evolution of blockchain-based systems has enabled researchers to develop nextgeneration e-voting systems. However, the classical consensus method of blockchain, that is, Proof-of-Work, as implemented in Bitcoin, has a significant impact on energy consumption and compromises the scalability, efficiency, and latency of the system. In this paper, we propose a hybrid consensus model (PSC-Bchain) composed of Proof of Credibility and Proof of Stake that work mutually to address the aforementioned problems to secure e-voting systems. Smart contracts are used to provide a trustworthy public bulletin board and a secure computing environment to ensure the accuracy of the ballot outcome. We combine a sharding mechanism with the PSC-Bchain hybrid approach to emphasize security, thus enhancing the scalability and performance of the blockchain-based e-voting system. Furthermore, we compare and discuss the execution of attacks on the classical blockchain and our proposed hybrid blockchain, and analyze the security. Our experiments yielded new observations on the overall security, performance, and scalability of blockchain-based e-voting systems.
