This paper presents a vote decision-based deinterlacing scheme for false directional error correction(VDD) to convert interlaced signal into non-interlaced signal using only one fields. The VDD using the vote decision goes through four steps process. The first step extracts regions having doubt of false edge using MM-ELA method. In these regions, the edge direction is decided by the majority vote using upper adjacent pixels's information through the second step. But, we still have undecided directions, which will be decided by the majority vote and the directional average decision at the third step. This step preserves the edge directions and minimizes visual degradation. Finally, the last step interpolates undecided pixels using DOI method which can consider the fine edge direction. Although the VDD with hierarchical structure has a high complexity, it can extract delicate edge compared to other pixel-by-pixel or window-by-window deinterlacing algorithms. Simulation results show that it has significantly improved both the subjective and objective qualities of the reconstructed images.

Sensor nodes are easily compromised by attacker when which are divided in open environment. The attacker may inject false report and false vote attack through compromised sensor node. These attacks interrupt to transmission legitimate report or the energy of sensor node is exhausted. PVFS are proposed by Li and Wu for countermeasure in two attacks. The scheme use inefficiency to energy of sensor node as fixed report threshold and verification node. In this paper, our propose the next neighbor node selection scheme based on fuzzy logic system for energy improvement of PVFS. The parameter of fuzzy logic system are energy, hops, verification success count, CH select high the next neighbor node among neighbor nodes of two as deduction based on fuzzy logic system. In the experimental, our proposed scheme was improvement to energy of about 9% compare to PVFS.

본 연구는 최근의 사회조사와 선거자료를 이용하여 한국사회의 지역주의의 특징을 살펴보고자 한다. 첫째, 최근의 선거결과에 보이는 지역주의적 투표는 지역간 사회적 거리를 잘 보여주고 있다. 둘째, 이러한 사회적 거리는 '편견과 차별'의 형태로 다양한 일상생활에서 존재하고 있다. 많은 사람들은 이러한 편견을 믿고 있으며, 편견에 의한 지역적 차별을 경험하고 있다. 특히 이러한 경험은 특정지역(호남)과 관련되어 있다. 셋째, 이러한 정치적 측면(지역주의적 투표)과 사회적 측면(지역간 편견)을 선거제도와 연결하여 살펴봄으로써, 앞으로 한국사회의 정치제도의 변화에 대한 전망을 할 수 있다. 연구의 잠재적인 가정은 선거에 있어서 지역적인 투표가 무조건 '나쁜' 것만은 아니라는 것이다. 한국 정치에서 나타나는 지도자나 이데올로기의 편향은 많은 사람들로 하여금 투표나 선거에서 출신지를 중요한 요소로 삼게 하였다. 이러한 요소는 쉽게 사라지지는 않을 것이며, 앞으로 선거제도의 변화에 중요한 역할을 할 것이다. 이러한 예측은 세 가지 중요한 요소에 근거하고 있다. 첫째, 유권자들의 지역주의에 대한 믿음과 예측은 쉽게 사라지지 않을 것이다. 둘째, 정치지도자들은 지역주의를 선거와 관련한 자신의 이익을 위해서 최대한 이용할 것이다. 셋째, 지역주의에 근거한 유권자들의 성향은 최근 선거와 투표에서 더욱 강화되고 있다. 정치엘리트들이 지역적인 기반을 중심으로 결합하려는 경향이 강해지고 있다. 이러한 경향은 이들 정치엘리트 사이의 내각중심제에 대한 선호도와 지역당의 출현 가능성을 증가시킬 것이다.도 설치행위의 처분성과 관련하여 횡단보도의 설치행위와 같은 일반적인 명령을 항고소송의 대상으로 할 필요성이 존재한다면 이른바 독일에서의 일반처분이라는 개념을 무리하게 받아들여 이를 행정행위의 한 유형으로 한다거나 우리 판례와 같이 "직접적이고 구체적인 법적 효과"를 미치는 명령이라는 명확치 않은 기준에 의하여 처분성을 인정하기보다는 일반적인 명령과 개별적인 행정행위를 구분하고 명령에 대하여도 취소소송의 대상으로 삼도록 하는 보다 명확하고 일관성 있는 논의전개를 제안하였다.수 있었다.로 첨가하여 48시간 배양한 후 암항원 유전자 발현성을 측정한 결과 세포주에 따라 다소 차이는 있으나 대개 0.2 uM농도에서도 유전자 발현이 유도되었으며 1, 5 uM농도에서 매우 강하게 유도되었다. ADC 처리가 페암세포주의 MHC와 B7 발현을 증가시키는가를 알아보기 위해 1 uM 농도의 ADC를 72시간 처치한 후 FACS 분석을 실시한 결과 4개의 페암세포주에서 MHC 및 B7분자의 발현은 유도되지 않았다. 또 ADC농도가 세포성장에 미치는 영향을 알아보기 위하여 ADC를 0.2, 1, 5 uM농도로 96시간 처치 후 세포수를 측정하여 상대성장지수를 알아본 결과 ADC 처치 농도가 증가함에 따라 세포의 성장은 매우 감소하였다. 결론: 폐암세포주에서 ADC처치는 MAGE, GAGE 및 NY-ESO-1과 같은 세포독성 T 림프구 반응을 유도할 수 있는 암항원의 발현을 증가시킬 수 있으며, ADC의 세포독성과 항원 발현 유발시간을 분석할 때 1 uM 농도에서 48시간 처치한 후 ADC가 없는 배지에서

This study explored the influence of media use on the audiences' intention to vote as well as their political cynicism in 2012 General elections. I offered three research questions: Research Question 1: What is the impact of media use on the political cynicism? Research Question 2: What are the impact of political intersest, political knowledge, media malaise, political efficacy on the political cynicism? Research Question 3: What is the impact of political cynicism on vote behavior? This study analysed survey data. Based on the results of hierarchial regression analysis and path analysis(AMOS), Internet news use was found to have a significant impact on the political cynicism. But the use of newspaper, TV news were not related to political cynicism. The political efficacy decreased political cynicism effectively, The findings from this study indicate that the relationship between media use and political cynicism is contingent on many factors and that cynicism has a negligible impact on citizen participation. This study also found that persons higher in efficacy were less cynical than low in efficacy. This suggest that cynicism is not always bad thing, that it may in fact be an indication of "an interested and critical citizenry". In conclusion this study showed that we need more in-depth analyses on the relationships among attention to media use, political cynicism and voting behavior to activate political participation.

The purpose of this study is to verify the effect of electoral competition on voters deciding on strategic split-ticket voting under the mixed-member electoral system. As result, the more competitive the constituencies are, the more voters choose to vote for the major parties. The results of logistic regression analysis including interaction terms showed that the more competitive the constituencies are, the more voters choose for candidates from the major parties. Also, the finding shows that major party supporters are less affected by electoral competition than minor party supporters in choosing a candidate in the single-seat districts. In the case of minor party supporters, the more competitive the constituencies were, the more likely they were to choose the major party candidate instead of the minor party candidate. Based on these results, it can be inferred that voters are affected by the presence or behavior of other voters in local constituencies under the first-past-the-post rule. Because of the psychology of not wanting their votes to be useless, voters cast their ballots more strategically as the competition in constituencies intensifies, and as the competition in constituencies slackens, such tendencies weaken, and this trait is particularly evident among minor party supporters.

Nowadays various public data have been serviced to the public. Through the opening of public data, the transparency and effectiveness of public policy developed by governments are increased and users can lead to the growth of industry related to public data. Since end-users of using public data are citizens, it is very important for everyone to figure out the meaning of public data using proper visualization techniques. In this work, to indicate the significance of widespread public data, we consider UN voting record as public data in which many people may be interested. In general, it has high utilization value by diplomatic and educational purposes, and is available in public. If we use proper data mining and visualization algorithms, we can get an insight regarding the voting patterns of UN members. To visualize, it is necessary to measure the voting similarity values among UN members and then a social graph is created by the similarity values. Next, using a graph layout algorithm, the social graph is rendered on the screen. If we use the existing method for visualizing the social graph, it is hard to understand the meaning of the social graph because the graph is usually dense. To improve the weak point of the existing social graph visualization, we propose Friend-Matching, Friend-Rival Matching, and Bubble Heap algorithms in this paper. We also validate that our proposed algorithms can improve the quality of visualizing social graphs displayed by the existing method. Finally, our prototype system has been released in http://datalab.kunsan.ac.kr/politiz/un/. Please, see if it is useful in the aspect of public data utilization.

This study aims to explore implications by analyzing voters' behaviors and attitudes of political campaigns & political advertising audience in the 19th presidential election. For this purpose, in-depth interviews with 59 voters who voted in the last election were conducted, and interviewees were allocated by their gender and age. As a result, the motivation to ballot for a candidate was based on the candidates' political affiliations to a party, political inclinations, and election pledges. Voters also determined whom they would vote for after watching the final TV debate. The biggest issue of this election was to create jobs in the public sector, an economical issue. TV was the most trusted medium among the voters, and TV debates had the greatest influence in changing the minds of the voters. Voters thought that Shim, Sang Jung was the best on TV debates and that An, Chul Soo was the worst. Also, voters recalled An, Chul Soo the most among all election posters, but they recalled Moon, Jae In the most out of other political advertisement methods. Therefore, the results elucidated the voters' behaviors and the audience's attitudes in political advertising, and this study provided theoretical and practical implications to be utilized in future presidential election campaigns and political advertising endeavors.

Electronic voting has been recognized as an alternative to complement the limitations of existing paper voting. At the same time, security concerns are being raised. This paper presents a blockchain-based electronic voting and survey system that can guarantee reliability. Our smart contract was created using Solidity on Ethereum which is a blockchain-based distributed computing platform, and the system was implemented in connection with the Javascript based user interface. In addition, in order to protect the personal information of participants, the system is generating hash of the personal data and storing the hash of users for the contract data. Since we exploited different kinds of languages for the system, we derived items of functionality testing and presented the functionality testing result. Moreover, we made use of the Chrome's performance evaluation functionality to see the response time of the blockchain-based system. In addition, we compared the performance with the system which has the same functionality on database. The contribution of this research is design and implementation of blockchain-based electronic voting system and presentation of the functionality and performance simulation result.

In this study, we proposed Interactive Visualization methods that can be analyzed relations between nations in various viewpoints such as period, issue using total 5211 of the UN General Assembly voting data.For this research, we devised a similarity matrix between nations and developed two visualization method based similarity matrix. The first one is Network Graph Visualization that can be showed relations between nations which participated in the vote of the UN General Assembly like Social Network Graph by year. and the second one is Proximity based Circular Visualization that can be analyzed relations between nations focus on one nation or Changes in voting patterns between nations according to time. This study have a great signification. that's because we proposed Proximity based Circular Visualization methods which merged Line and Circle Graph for network analysis that never tried from other cases of studies that utilize conventional voting data and made it. We also derived co-operatives of each visualization through conducting a comparative experiment for the two visualization. As a research result, we found that Proximity based Circular Visualization can be better analysis each node and Network Graph Visualization can be better analysis patterns for the nations.
