In the 21st general election held in April 15, 2020, the importance of social media as an election campaigning tool became more prominent when engaged with Corona 19. Therefore, in this study, various studies were conducted to establish SNS strategy as an election campaign tool. This study analyzed the contents of SNS (Facebook, Twitter, YouTube) activities as an election campaign tool to analyze messages on social media messages of candidates Lee Nak-yeon and candidate Hwang Kyo-an of Jongno-gu, Seoul during the 2020 21st National Assembly election. Data collection mainly analyzed posts from each candidate's official account, and the research method used text analysis using the R program. Word cloud, comparative analysis, q-graph analysis, LDA, and STM analysis were used during text analysis. In addition, the analysis result was confirmed to be statistically significant through correlation analysis. As a result of research, candidate Lee Nak-yeon's election includes corona, people, problems, crisis, suffering, and wisdom, which indicates that the crisis caused by corona must be overcome through any means possible. On the other hand, candidate Hwang Kyo-an's election includes Moon Jae-in, the regime, save, the fatherland, the judge, and the economy. And from the perspective of political publicity, candidate Lee Nak-yeon made a lot of acclaims, while candidate Hwang Kyo-an made a lot of attacks, and both themes emphasized the policy rather than the image.

Visual images are very close to our living and we make decisions and choose behavioral options with the visual images on mass media. In current-affair documentary programs, interviews have potential effects that can change public opinions on important issues. Therefore, it's a consequence that the study examined how different expressions of visual images in documentary. Using preceding research methods, this study focus on form, color, movement and depth of visual images. This study analyzed quantitatively all interview shots with 15 current-affair documentary programs from major TV stations such as KBS, MBC and SBS. The findings of the study are 1) half of interview shots used the visual image expressions to hide interviewees' face according to the shield law, 2) choosing close-up shots in company with bust shots, 3) using natural lights and hand-held camera techniques for interviews, and 4) showing wide angles without depths of visual image.

The purpose of this study is to review educational value of cultural heritage sites first and then, to examine the importance of interpretation and interpretation methods and process briefly to utilize cultural heritage sites as important resources for public education and cultural tourism. The educational value of cultural heritage sites is not limited to provide visitors with various information on historical facts and events related to the cultural heritage site, but to provide the public with a new recognition of the importance of the preservation of cultural heritage sites by understanding the site well. In order to utilize the educational value of the cultural heritage site, interpretation must be emphasized as an important element of cultural heritage sites management and much attention should be given on the development and practice of interpretation programs in each cultural heritage site. In order to develop an interpretation program of the site, a specific target audience must be defined first to find most resonable scope and direction of an interpretation program and then, site specific interpretation themes (or a theme) should be developed from the interpretive topic. According to these defined elements, an interpretation program(s) is established by using various interpretation methods and techniques in order to provide visitors with useful information and knowledge on the site efficiently. Interpretation methods and techniques are various as defined by various ways and most effective methods or techniques are employed as a specific interpretation program is presented most effectively. The evaluation processes in planing stage, during developing stage, and after completion of interpretation program development are important processes to find out any problems of planed interpretation program and to revise or update the interpretation program. Conclusively, the direction of cultural heritage sites management in Korea has focused on the conservation and restoration of cultural heritage sites to preserve the original conditions of cultural heritage sites so far. This direction on current practice on cultural heritage sites management should he changed to more active utilization of the sites and interpretation of the sites is a way to accomplish the this goal.

Typography is the field be needed the most emotional and potential originality in the visual designers works. The design process introduced by aesthetic results is depended on a designers sensibility and originality. Accordingly this study includes more detail suggestions for mental switchover and developing whole area of sense and its education which make more sincere and easy communication of sentences in typographic and messages, removing fixed ideas, that are, prejudice and preconception, is one of big problems in making originality through the educational programs for experimental typography approaching with a new vision. Today, the change of typographic environment carried the substance and effectiveness of traditional typography be suspected and new ways are growing fast to escape from these traditional value. This study introduces some education programs such as Typortrait, Typeface, Typographic Essay, Kinetic Typography to realize the experimental typography to meet a new stream and social needs under the situation of exoplosive change and harmony fairly with proposition of coexisting of inspiration and technology, and finally expected to develop and promote typography experiment newly and to make educational section understand and confirm them.

Background: Even though cervical cancer poses a significant global cancer burden, successful implementations for early detection offer an opportunity to prevent deaths and reduce the cancer burden. In Korea, cervical cancer is the most prevalent type of cancer among adult women, but it is one of the few cancers in which a consensus-approved screening test exists for early diagnosis, Pap test, that can be combined with highly efficacious treatment regimens for early-stage disease. Purpose: This study was carried out to identify the cognitive-behavioral factors associated with cervical cancer screening behavior among adult women, aged 40 to 59, and to develop tailored messages and to evaluate the effectiveness of stage-matched educational program. Method: A total of 283 women who aged 40 years or older was recruited in Seoul, from September, 1st to November, 14th, 2003. The intervention group (N=162) and the control group (N=121) were selected from five sub-districts in Seocho-gu, Seoul. Building on the TTM, a quasi-experimental study was conducted to test the effectiveness of stages-matched intervention addressed at the five stages of cervical cancer screening behavior. Women in the intervention group were randomly assigned to one of two conditions, internet or postal services. Results: In our results, 88.9% of participants had received a Pap test at least once in their life-time, and 65.4% had got it in the past two years. With regard to cognitive-behavioral factors, the stages-matched educational program increased attitude and process of change for cervical cancer screening. The percentage changed was the largest in maintenance stage. With regard to delivery methods for tailored messages, the print materials were more effective at increasing screening adherence than the e-mail. Whereas the postal service group showed remarkable the change of behavior stage, the internet service group did not. Also it was not shown any difference of the satisfaction with stages-matched educational program between internet and postal service groups. Conclusion: This study suggested that cervical cancer screening behavior could be changed by tailored messages which had developed with cognitive-behavioral factors. The stages-matched educational program was effective to promote the screening adherence for cervical cancer.

This study attempts to explore the inter-media agenda setting effect between television and Twitter based on the framework of the two-step flow theory. Twitter's increasingly important role in political communication can be effectively addressed by examining the process by which Twitter users form their opinions on television debate program. Content analyses of Twitter discussions after television debate of the Korean presidential candidates provided interesting insights into how Twitter's opinion leaders reflect on the televised debates. The results show that Twitter mentions rather focus on personality traits of the candidates while television debates emphasize the candiates' policy issues. Specifically, Twitter users mainly concentrated on the political ideology and morality of the candidates. In sum, Twitter seems to have its own way of influencing the public opinion separately from the television.

유비쿼터스 컴퓨팅 환경의 인프라는 센서, 미들웨어, 그리고 응용 프로그램으로 구성된다. 유비쿼스터 컴퓨팅 환경이 실현되기 위해서는 이 세 요소들은 상호 유기적으로 메시지를 전달해야 한다. 특히 센서와 미들웨어간의 통신은 이 점에서 중요한 역할을 한다. 본 논문에서는 센서와 미들웨어간의 통신 메커니즘을 지원하는 아키텍쳐를 제안한다. 기존의 시스템에서는 센서와 미들웨어 사이에서 통신 기능을 담당하는 컴포넌트는 데이터와 이를 처리하는 기능이 함께 존재했다. 그렇기 때문에 데이터를 처리 기능이 같을지라도 받아 들이는 데이터가 다르고 처리하는 정보가 다르다면 센서 수와 같은 컴포넌트가 존재해야 한다. 또한 센서와 미들웨어간의 통신 기능을 담당하는 컴포넌트를 만들기 위해서는 미들웨어와 센서에서 제공하는 API 를 이용하여 개발자가 직접 코딩작업을 해야 한다. 이럴 경우 개발자의 시간과 노력이 많이 필요로 한다. 두 문제점을 해결하기 위하여 먼저 데이터와 이 데이터를 처리하는 부분을 분리시킨다. 이러한 메커니즘은 SNMP 에서 도입하였다. SNMP 를 구성하는 요소 중에서 자료를 처리하는 부분은 에이전트가 맡고, 자료를 저장하는 부분은 MIB 이 맡는다. 그 결과 해당 컴포넌트의 재사용이 가능하게 된다. 또한 MIB 과 에이전트의 개발 시간을 단축하기 위해서 SNMP 를 이용한 툴킷을 이용한다. 이렇게 함으로써 센서측과 미들웨어 사이에 통신하는 컴포넌트를 개발하는 시간과 개발자의 노력의 효율성을 증대 시킬 수 있다.

유비쿼터스 컴퓨팅 환경의 인프라는 센서, 미들웨어, 그리고 응용 프로그램으로 구성된다. 유비쿼터스 컴퓨팅 환경이 실현되기 위해서는 이 세 요소들이 상호 유기적으로 메시지를 전달해야 하며, 구성 요소를 구성하는 개체들에 대해서 존재 유무를 파악할 수 있어야 한다. 우리는 센서와 미들웨어간의 통신을 위한 컴포넌트를 쉽게 만들기 위하여 망 관리에서 사용되었던 SNMP 를 이용하였다. 하지만 SNMP 를 적용한 구조에서는 동적으로 변화는 센서에서 무방비한 입장이었다. 다시 말해서 동적으로 변하는 센서나 혹은 그 속성값들이 변할 때, 그 시스템의 전문가가 직접 통신 컴포넌트를 수정해야 했다. 또한 센서들이 접하게 될 플랫폼들이 여러 종류가 있기 때문에 센서를 만드는 벤더들 또한 여러 버전의 API 를 제공해야 한다. 따라서 본 아키텍처는 센서나 그 속성값들이 변할 때 사람에 의해서 조작하지 않고 시스템 스스로 설정하며 그 센서들을 사용할 수 있도록 하고, 벤더들의 수고를 덜어 줄 수 있는 아키텍처를 제안한다. 이러한 메커니즘은 기존 망 관리에서 사용했던 AgentX 에서 착안하였다. AgentX 프로토콜의 메커니즘을 이용함으로써 사용자의 입장에서 센서에 대한 Transparency 를 보장 받을 수 있으며, 부수적으로 센서를 만드는 벤더들은 여러 버전의 API를 만들어야 할 수고를 덜게 되었다.

Low-cost commodity SMP(Symmetric Multiprocessor) is widely used as a node of cluster system. In this paper, we implement and evaluate the performance of SDSM system for SMP clusters. Our SDSM system provides HLRC(Home-based Lazy Release Consistency) memory consistency model. Our protocol utilize shared memory within same SMP node, so that page fetch and message passing through network can be reduced. It is implemented on 8 node of 2-way Pentium-III SMP interconnected with 100Mbps Fast Ethernet, and uses TCP/IP for transport/network layer protocol. The experiment with eight applications shows that our SMP protocol achieves maximum 33% speedup improvement and 13%-52% reduction of page fetch compared with uniprocessor protocol.
