본 연구는 셀프 프리젠테이션 이론과 프레밍 효과론을 논리적 근거로 해서 지역공동체 구조의 특성과 뉴스프레밍 사이의 관계를 가설로 설정하고 있다. 따라서 뉴스 프레밍분석을 위해서 1994년 당시 미시간에서 발행되던 9개의 일간지를 내용 분석했으며, 지역공동체 구조와 관련해서는 1990년의 미시간 주의 인구조사 보고서 상에 나타나는 4개의 인구사회학적 변수(직업, 수입, 교육, 인종)와 한 개의 인구이동 변수를 이용해서, 각 카운티별로 이질성의 정도가 순위 매겨졌다. 마지막으로 종속변인인 투표행위 값으로는 각 카운티에 사는 유권자의 총수를 당시 미시간 주의 주지사이자 후보자였던 엥글러(Enlger)에 대한 투표자 수로 나누어서 나오는 백분율을 이용해서 엥글러 지지율을 얻었다. 이상의 데이터를 가지고 회귀분석을 시행, 다음과 같은 결과를 얻었다. 대새몰이형 프레임은 지역민의 인구사회학적 속성이 이질적인 지역보다는 동질적인 지역에서 보다 투표행위에 영향을 많이 미치며 이에 비해 사회 정체성 프레임은 지역민의 인구사회학적 속성이 이질적인 지역에서 보다 효과적이었다.

Attention plays vital role either students academic performance in classroom or work performance of workers. This study was accomplished among elementary school students of elementary school classroom for two years. Three experiment cases were designed based on the Predicted Mean Vote (PMV) indexes. Thermal environment and PMV were directly monitored; Thermal Sensation Vote (TSV) and Comfort Sensation Vote (CSV) were analyzed based on survey data; and attention was analyzed for different comfort level using FAIR program. PMV, TSV and CSV were varied with the change in thermal environment and there was not noticeable gender influence on impact. The good correlation between thermal environment, PMV, TSV and CSV confirmed the impact of thermal environment on indoor comfort. There were different impacts on attention with comfort conditions. Academic attention of low attention group i.e. weak students, can be improved by providing the comfort environment. Thermal environment influences the comfort and the comfort influences the attention, it is possible to assess the impact of thermal environment on attention in further.

A self-diagnostic monitoring system is a system that has the ability to measure various physical quantities such as temperature, pressure, or acceleration from sensors scattered over a mechanical system such as a power plant, in order to monitor its various states, and to make a decision about its health status. We have developed a self-diagnostic monitoring system for an air-operated valve system to be used in a nuclear power plant. In this study, we have tried to improve the self-diagnostic monitoring system to increase its reliability. We have implemented three different machine learning algorithms, i.e., logistic regression, an artificial neural network, and a support vector machine. After each algorithm performs the decision process independently, the decision-making module collects these individual decisions and makes a final decision using a majority vote scheme. With this, we performed some simulations and presented some of its results. The contribution of this study is that, by employing more robust and stable algorithms, each of the algorithms performs the recognition task more accurately. Moreover, by integrating these results and employing the majority vote scheme, we can make a definite decision, which makes the self-diagnostic monitoring system more reliable.

열 쾌적 제어는 실내 환경의 질을 나타내는 기본 요소로써 건물에서 사용되는 에너지와 거주자의 만족도에 매우 밀접하게 연관되어 있다. 본 논문에서는 실내의 쾌적 상태(Predictive Mean Vote)를 검출하고, 목표 소비 전력 내에서 냉난방 온도, 습도, 풍량을 제어함으로써 에너지를 절감하고 근무자에게 쾌적한 환경을 제공할 수 있는 스마트 쾌적 제어 알고리즘을 제안하였다. 시뮬레이션 결과, 열 쾌적 제어에 의한 냉난방제어는 기존의 일반 냉난방기에 비해서 실내의 쾌적도는 그대로 유지한 상태에서 0.5kW의 전력을 절감할 수 있고, 조명제어 알고리즘이 적용된 조명 제어에 의해서 49.2%의 조명 개선 효과가 이루어짐을 알 수 있었다. 시뮬레이션을 통해서 검증된 쾌적 제어 알고리즘을 기존의 냉난방기에 적용할 경우 쾌적도는 유지하고 에너지는 절감할 수 있을 것으로 예상된다.

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.

Leader and leadership are one of the important aspects in the life of a country. This study aims to predict the intention of young voters to vote for state leader elections by expanding the theory of planned behavior to the Indonesian context. Apart from the importance of the presidential election, research rarely uses the theory of planned behavior, and to the best of researchers' knowledge, there are no studies that have applied the theory of planned behavior to predict the intention to vote for the president. Therefore, this study is an attempt to fill that gap. Two hundred questionnaires were distributed using non-probability purposive sampling. Data analysis was carried out using the structural equation modeling (SEM) approach. The results showed that attitude and behavior control were positively related to voters' intention to elect presidential candidates. Furthermore, information from social media also has a positive relationship with the attitude of choosing presidential candidates. However, the results also show that subjective norms do not have a significant relationship with voters' intention. This study contributes knowledge to researchers, practitioners, and policymakers about the factors that influence youth intention to vote in Indonesia, namely, attitudes, perceived behavior control, and information from social media.

With the development of information and communication technologies, especially wireless networks and cell phones, the e-voting system becomes popular as its cost-effectiveness, swiftness, scalability, and ecological sustainability. However, the current e-voting schemes are faced with the problem of privacy leakage and further cause worse vote-buying and voter-coercion problems. Moreover, in large-scale voting, some previous e-voting system encryption scheme with pairing operation also brings huge overhead pressure to the voting system. Thus, it is a vital problem to design a protocol that can protect voter privacy and simultaneously has high efficiency to guarantee the effective implementation of e-voting. To address these problems, our paper proposes an efficient unidirectional proxy re-encryption scheme that provides the re-encryption of vote content and the verification of users' identity. This function can be exactly applied in the e-voting system to protect the content of vote and preserve the privacy of the voter. Our proposal is proven to be CCA secure and collusion resistant. The detailed analysis also shows that our scheme achieves higher efficiency in computation cost and ciphertext size than the schemes in related fields.

The thermal comfort of indoor spaces is very important factor in our life. Regions, cultures, climates and individual difference for establishing thermally comfortable environments should be considered carefully because these factors have a large influence on the thermal comfort doing some complicated interactions with environmental, psychological and physical elements. Recently, predicted mean vote(PMV) based on the heat transfer theory between environmental factors and human bodies has evaluated by many researchers and widely used nowadays. The objective of this study is to evaluate the thermal comfort in workspaces with personal air conditioning system using the measurements of environmental comfort parameters and the questionnaire survey of occupant's thermal senses with response to the environment.
