본 연구에서는 직접평균법의 공간, 시간 및 ensemble 평균방법들 대신 공간변 수에 관한 convolution의 일관된 방법을 사용하며, 점근해석법의 범함수해석보다 기초 적인 방법으로, 혼합연속체이론의 등가균질체(equivalent homogeneous body)와 같은 추상적 모델 대신 혼합체의 자연적 모델에서 출발한다. 또 참고문헌(11)의 평균방법 인 4중적분의 연산대신 convolution과 체적 distribution을 조합하여 비균질체 일반의 유효장 방정식(effective field equation)들을 도출하고 검토한다.

분산 멀티미디어 문서 시스템은 네트워크로 연결된 여러 서버에 있는 미디어들은 검색하여 제시된 시간 관계에 따라 미디어들을 프리젠테이션한다. 효과적인 프리젠테이션을 위해서는 동기화가 지원되어야 하며, 특히, 분산 환경에서의 프리젠테이션은 네트워크 대역폭과 지연시간 등에 의해 영향을 받기 때문에, 그러한 요소들이 고려되어 동기화가 지원되어야 한다. 본 연구에서는 미디어들이 각 서버로부터 전송 될때 네트워크의 상태와 자원을 검사하여 그에 따른 변화를 서버에 피드백시켜, 서버로부터 전송되는 데이터의 양을 조절함으로서 동기화를 지원하는 분산 멀티미디어 프리젠테이션 모델을 제안한다.

Fundamentals of electrodynamics of moving sources with constant velocity in an anisotripic plasma when the do magnetic field and the relative motion are oriented in arbitrary directions are presented. The well-known Minkowski's relations are generalized to accomodate anisotropic and dispersive media, and relativistic transformation formulae of constitutive parameters are derived and expanded into polynomials of the speed ratio \ulcornerto increase the utility of the formulae. The helmholtz wave equation of electromagnetic fields is generalized to the media charactrized by tensor parameters, and is solved in operator form. Also the solution of wave equation is expressed as a porcuct of the inverse of the wave operator matrix and the source function vector, and the inverse of the wave operator matrix is presented in an explicit form. The equations and formulae derived in this paper are all general, and can be reduced to known and proven results upon imposing the restriction called for by specific situations.

본 논문에서는 문헌연구 및 소비자 대상 표적집단면접(FGI)을 중심으로 뉴미디어 광고환경에서 광고를 활용한 관계 형성 및 유지에 관해 연구하였다. 광고는 소비자와 브랜드의 관계에 있어서 시간의 흐름에 따라 관계를 형성하기도 하고 변화시키기도 하는 것으로 나타났다. 반면 광고로 인하여 브랜드와의 관계가 손상되는 경우도 발견할 수 있었다. 소비자-브랜드 관계를 형성하는데 있어서 광고모델, 음악, 광고집행 프로그램 등이 광고의 주요 관련 요소로 기능하는 것을 발견할 수 있었다.

The article examines one of the most important means of visualization of mass information on the Internet - information graphics in the broadest sense of the term as a visual technology for presenting mass information. The main objectives of the article are to determine the genre-typological features of infographics and basic technological principles; identification of features of creation and use of information graphics in modern network. Certain benefits of online infographic editors include savings in resources and time. They allow the user, who has basic PC skills, to create standardized infographics based on their own data. In addition, the use of online services develops visual thinking, allows you to get an idea of quality criteria and current trends in infographics, as well as to gain initial experience in the visual presentation of data.

This paper studies how marriage migrants are being depicted in Korean Cinema. In the recent years, the foreign population in South Korea has been increasing and so has done the presence of migrant minorities in media, including cinema. This study discusses that korean cinema shows dominant ideologies of power in Korean society where marriage migrants are located at the bottom. Five films were analyzed and from this analysis five frames were extracted. Marriage migrants are frequently depicted as subordinated or powerless, they are usually women in the role of wives, mothers, and daughters-in-law, they are treated as ethnic others, sexualized others or commodities. Consequently, their relationships with Korean nationals are formed by power relations. Moreover, Korean national who do establish some sort of intimate relationship with the marriage migrants are represented as people in the margins of Korean society. In this way, it is reinforced the social position of marriage migrants as outsiders in the Korean society.

In the 21^st century, the growing use of information and communication technologies (ICTs) and social media platforms has influenced our way of life, including international diplomacy. With the use of new interactive communication technologies such as WhatsApp, Twitter, Facebook, Instagram, video sharing website, blogs, and other social media networks, digital diplomacy has become an active diplomatic mode in modern society and plays an increasing important role in international relations. Although Indonesia has gradually realized the pivotal role of internet diplomacy and recently put it into practice, it is still lagging far behind. This paper will examine how Indonesia conducts its diplomacy in the new era of digital world. How far and in what ways does the Indonesian government make use of digital technology to conduct its diplomacy? What opportunities and challenges are confronted to develop digital diplomacy? How does it navigate diplomacy in the digital age? Unless Indonesia embraces new channels and methods of diplomacy, its foreign policy implementation may not run optimally to support its aim of attaining its objectives in the international stage.

Harvest forecasting is the great demand of multiple aspects like temperature, rain, environment, and their relations. The existing study investigates the climate conditions and aids the cultivators to know the harvest yields before planting in farms. The proposed study uses federated learning. In addition, the additional widespread techniques such as bagging classifier, extra tees classifier, linear discriminant analysis classifier, quadratic discriminant analysis classifier, stochastic gradient boosting classifier, blending models, random forest regressor, and AdaBoost are utilized together. These presented nine algorithms achieved exemplary satisfactory accuracies. The powerful contributions of proposed algorithms can create exact harvest forecasting. Ultimately, we intend to compare our study with the earlier research's results.

In consideration of limitations of the classic economic approach to risk evaluation and the psychometric analysis of risk perception, this study applies a facilitated modeling technique to a group of college students in Korea. In this group activities, researchers did not provide a pre-selected list of risk items. Instead, 35 participants had group discussions to generate 63 risk items, to rate their risk level and to evaluate their characteristics in terms of the level of knowledge and dreadfulness. This study also analyzes the influence of mass media, online news papers in particular, on risk perception by counting the number of news articles covering key word corresponding risk items generated. The results show that there are significant differences between the rank order of risk items generated by students and that of statistical or objective risk. Psychometric analyses find that the levels of knowledge and dreadfulness have meaningful correlations with risk level. A well known or a dreadful risk demonstrates a high level of risk. Correlation analyses of media coverage and the risk level also re-confirms strong positive relations. The larger number of news articles a risk issue was covered by, the higher level of risk it showed. It means that college students generated risk items on the basis of what they were exposed by media. The role of mass media in risk perception and the importance of risk communication in risk evaluation are underlined. Implications of research findings and future research are discussed as well.
