A Multilinear LDA Method of Tensor Representation for ECG Signal Based Individual Identification Electrocardiogram signals, included in the cardiac electrical activity, are often analyzed and used for various purposes such as heart rate measurement, heartbeat rhythm test, heart abnormality diagnosis, emotion recognition and biometrics. The objective of this paper is to perform individual identification operation based on Multilinear Linear Discriminant Analysis (MLDA) with the tensor feature. The MLDA can solve dimensional aspects of classification problems in high-dimensional tensor, and correlated subspaces can be used to distinguish between different classes. In order to evaluate the performance, we used MPhysionet's MIT-BIH database. The experimental results on this database showed that the individual identification by MLDA outperformed that by PCA and LDA.

This paper describes the development of the 3DDAC mk.4 system, which is a brand new implementation on the research program. The 3DDAC is a fatigue-less stereoscopic display system that is provided with a compensating function of accommodation for binocular disparity 3D image representation. The mk.4 system also features a light-weight HMD style.

The purpose of this study is to analyze modern fashion culture in the 20th century through changes in transmedia in order to better understand characteristics of fashion contents. The study also strived to identify the characteristics of remediation in modern fashion and media by exploring the cultural code, and use it to establish an integrated view. The subjects and the method of the study are as follows. First, the study analyzed the development of transmedia and fashion culture since the 20th century. Second, it identified the transitional characteristics of transmedia. Third, the study analyzed the characteristics of remediation in modern fashion culture by using the characteristics of mediation, which appeared with the transitional characteristics of transmedia. The study results are as follows. First, the types of remediation are 'borrowing,' 'Representation,' 'Expansion,' 'Refashion,' and 'Absorb.' In old and new media, each type can be aesthetically experienced in 'transparency,' opaqueness,' 'Hypermediacy,' and 'Immediacy.' Second, fashion culture can undergo a transformation from its original form to a second and a third iteration, and this process allows for possibility of an expansion of multiple plots and well-rounded character settings. This opens up the possibility for fashion consumer participation, and signifies a transition into an environment where expansion of time and space is possible. The third finding is the non-mediation of fashion objects. The mediating relationship between clothes and media is directly connected to the development of new media. The immersion of new media by fashion consumers has the characteristics of 'transparency'/'Non-mediation,' and the reinterpretation and reproduction of original fashion styles have the characteristics of 'opaqueness'/'Hyper-mediation.' Fourth, fashion culture has data variability. Through 'Borrowing,' 'Representation,' 'Expansion,' 'Remodeling,' and 'Absorption,' the cultural hierarchy of reproduced fashion forms a multi-layered integrated network. Mediation code, which repurposes fashion culture contents, also creates new media fashion through transmedia.

RoSE(representation of sensory effects)기술은 A/V미디어에서 제공하는 시청각 효과 이외에 바람/향기/진동 등의 실감효과를 팬/발향기/진동의자 등의 다양한 디바이스와 연동시킴으로써 미디어의 실감효과를 극대화하는 기술이다. 2007년 10월 82차 MPEG회의에 처음 제안된 RoSE프레임워크는 SE(sensory effects), USP(user sensory preferences), SDC(sensory device capabilities), SDCom(sensory device commands)의 표준아이템이 상호 연동하는 시스템 구조를 갖는다. 지난 2월 87차 MPEG로잔(Lausanne)미팅에서는 이들을 현실과 가상을 연결하는 인터페이스 표준을 정하는 MPEG-V(ISO/IEC 23005) 프로젝트의 Part 2(control information)와 Part 3(sensory information)으로 분리 배치하고 오는 7월 89차 런던 미팅에서 CD(committee drait)를 목표로 표준화를 진행하고 있다. 본 논문에서는 XML에 기반한 이들 4개의 표준 아이템 구성을 살펴보고 현재까지 MPEG 에서 진행되어 온 RoSE표준화 과정을 소개한다.

The double layer screen plate tensioned with two sheets screen mesh is more thicker than that of one screen sheet. The double layer screen plate piled up with two sheets screen 200# or overlapped with a sheet screen 110# and a sheet screen 305# is more thicker than single layer screen plate with one sheet screen 420#. As the screen plate composed of two sheets screen has more accumulated ink capacity than one sheet of screen, printing printed with it has a good plasticity. And the single layer screen plate that accumulate a small quantity of ink has an excellent representation than the double layer screen plate but lower plasticity.

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.

Virtual source location information (VSLI) has been newly utilized as a spatial cue for compact representation of multichannel audio. This information is represented as the azimuth of the virtual source vector. The superiority of VSLI is confirmed by comparison of the spectral distances, average bit rates, and subjective assessment with a conventional cue.

This study aims to identify the representation of migrants in the English-language media during the Brexit campaign period. For the purpose of this study, the methodological tool of corpus-assisted discourse studies(CADS) was employed and a collection was compiled of articles mentioning Brexit in British, American, Canadian, and Australian media from April 15 to June 22, 2016 in order to compare their portrayals of migrants. To examine how IMMIGRANT, MIGRANT, and REFUGEE are represented in the media, their collocates were analyzed by MI score and categorized by social actor categorization(Van Leeuwan, 1996). The results show that IMMIGRANT is related to collocates that refer to legal status and provenance, MIGRANT associated with economic terms, and REFUGEE relates to terms expressing quantities. The results also reveal that migrants are frequently depicted by functionalization, classification, and appraisement categorization and are more negatively portrayed in British and American media. This paper claims that corpus-assisted linguistic analysis of words enables one to identify salient linguistic patterns or lexical choices in the discourses about a particular phenomenon or group of people.

In this paper, a multimedia authoring system using temporal/spatial synchronization manager is designed and implemented to support easy and efficient generation of multimedia title. For this goal, a flowchart-oriented logic generator which represents a title author's design intent into a practical title composition logic without extra translation process, and a logic interpreter which translate and implement the generated title logic, are designed. Furthermore, a temporal/spatial synchronization manager which manages temporal/spatial synchronization information between media data for multimedia representation, is designed. Especially, a temporal specification model and MRL, a formal language for the model, are designed to synchronize the temporal relation between media objects. The MRL represents a complex temporal relation by simple and clear form, and synchronizes efficiently multimedia representation according to the author's intent. A presentation frame editor which makes coincidence between visible size of representation media and attachment point, is implemented for spatial synchronization.
