The purpose of this research is to examine track suits which appear in mass media and to attempt to understand their embedded symbolism. Hence, a theoretical inquiry and case study on suit tracks were carried out. The case study was confined to the period since 2000, when sportswear emerged as a megatrend in fashion, to 2012. Occurrences of track suits in film, TV dramas, music videos, advertisements, and fashion collections were examined. Research indicated that the track suits in film or TV drama worked as items to give a change to coordination, material and decoration, so that the track suits highlighted the characters in them rather than emphasizing external factors or their own design. They were used as tools to indicate the sensual and dynamical feminine image in the rap and hip hop genres in music video. They also showed the dynamic image of modern woman via advertisements of sports brands. In the case of celebrity fashion, both inside and outside Korea, they introduced the track suits in a comfortable and sensual manner through both official and unofficial image releases. In the fashion collections, transboundary deconstructiveness was strongly expressed in terms of design, material, color, and production method. The case study in this research indicated that the symbolism in track suits was characterized as transboundary deconstruction as well as value in dynamic femininity, and products from reactionary nostalgia.

In the digital information age, image processing is essential for various digital devices such as smart phones, cameras, and TVs. However, degradation occurs in analyzing, recognizing, and processing image data, and salt & pepper noise occurs. Therefore, in this paper, we applied linear interpolation method, newton interpolation method, lagrange interpolation method, and spline interpolation method to the image damaged by salt & pepper noise in order to find more effective interpolation method in salt & pepper noise environment, The methods were compared using the PSNR (peak signal to noise ratio).

As the COVID-19 pandemic hits the world, the Tokyo Olympics in 2021 will be held behind closed doors. Some broadcasters showed the heart rate of the players in real time using image processing-based non-contact measurement to convey the vividness of the scene on TV. However, since the non-contact model uses changes in the skin color of the players' faces according to blood circulation as a parameter, there is a possibility that errors may occur due to interference factors such as natural light or glasses. Therefore, in this paper, the non-contact heart rate measurement model and the contact heart rate measurement model are tested in an environment free from interference and their accuracy is analyzed.

Recently virtual advertising is located in an important area of interest in the TV market by convenience of application and reduction of cost. The methods of inserting a virtual advertising in broadcasting are Up-link that method insert the image through the production equipment of the broadcasting station and dispatch equipment and technical personnel in the shooting and Down-streaming that method insert a virtual image automatically in relay video using image processing technology. In recent years, the image processing technology is an important research area in the virtual advertising area for automatically insertion of advertising images. In this paper, we propose the method to extract less-informative region in sports video using image processing. The proposed method extracts less-Informative region through rectangle detection of Hough transform and analysis of color histogram distribution.

Artificial Intelligence (AI) techniques have been effectively used for image classification, object detection, and image segmentation. Along with the recent advancement of computing power, deep learning models can build deeper and thicker networks and achieve better performance by creating more appropriate feature maps based on effective activation functions and optimizer algorithms. This review paper examined technical and academic trends of Convolutional Neural Network (CNN) and Transformer models that are emerging techniques in remote sensing and suggested their utilization strategies and development directions. A timely supply of satellite images and real-time processing for deep learning to cope with disaster monitoring will be required for future work. In addition, a big data platform dedicated to satellite images should be developed and integrated with drone and Closed-circuit Television (CCTV) images.

현재 수 많은 공중파 채널을 비롯하여 각종 케이블 TV 와 위성 TV 등의 채널이 대량으로 디지털화 되어 가고 있지만 파국의 디지털 TV 의 규격은 MPEG2 라는 표준 규격으로 통일 되어 우리에게 전해지고 있다. 이런 수많은 동영상 정보들은 디지털이라는 특성상 기록과 보관이 용이하므로 사용자는 수 많은 정보를 저장, 관리 할 수 있게 되었다. 따라서 방대한 데이터의 바다 속에서 원하는 정보를 검색하는데 있어서 기존의 방식 즉 일정 속도를 가진 검색 엔진을 사용하는 것 보다는 MPEG2 규격의 표준들을 보다 효율적으로 이용하여 사용자들이 동영상 정보 중에 이동하기 원하는 부분으로 이동하기 위한 비선형 검색엔진을 소개한다. 이를 이용한 PVR(Penonal Video Recorder)은 현재 hardware 부분은 완료되었고 일부 software 엔진을 적용하여 개발 중이다.

The purpose of this study was to define 'sponsorship' as a kind of advertising tool, and to describe its effects on consumer brand attitude and actual purchase behavior. From previous research results, clothing sponsorship was defined as 'indirect advertisement', which has common ad traits as well as the uncommon ad traits, such as indirectness, emotional affinity, and symbolism. Results from empirical research using 1,227 data collected in Seoul and Kyounggi Areas were as follows ; (1) Television drama clothing sponsorship was proved to have effects on brand image, emotional & rational brand attitudes, decision making process, and actual purchase behavior. (2) Each of drama clothing sponsorship factors, such as 'drama', 'role', and 'actress', had different effects on brand memory and attitudes. (3) Consumer decision making process initiated by drama clothing sponsorship followed two different processes, which were called 'rational' and 'heuristic'. The rational process followed every steps of EKB model, which explained consumer's rational shopping, but heuristic model was closer to emotional and impulsive shopping.

This study focuses on understanding the design characteristics of interior styles reflected in contemporary residential spaces by choosing and analyzing some design cases, reflecting interior styles of various countries, which is broadcasted through an interior design cable television in the U.S. Moreover, this study is meaningful because it provides a chance to extend the scope of study to the improving and developing Korean interior style for clarifying Korean identity to make Korean image by the comparison with other cultural spheres. In this study, after sorting 10 interior- style types and 90 design cases from the 12 cable television that mainly manage interior design projects, I grasp interior-design characteristics of each cases classified by form/expression and material. Research objects of the form/expression part for the interior-design characteristics are limited to furniture, textile, and ornaments, and those of material part are limited to furniture and ornaments.

In this paper, an X-Y channel dimming light emitting diode (LED) backlight with temperature compensation for in LCD TVs is proposed. It shows local dimming effects such as reduced power consumption and high dynamic contrast ratio even with much less number of LED drivers than that of the conventional two-dimensional local dimming method. Moreover, the image distortion caused by temperature variation of LED block can be effectively compensated. The validity of the proposed dimming method is verified by simulation and experimental results based on a RGB-LED backlight of a 32-inch LCD TV.

We have successfully commercialized a novel optical compensation film, OCB-WV film, for OCB-LCD-TVs which has fast response time and wide viewing angle. The OCB-WV film consists of a 45degree-aligned discotic layer and a high Rth biaxial TAC film, which is suited for a roll-to-roll polarizer manufacturing process. This OCB-WV has brought out the excellent features that OCB intrinsically has, making nextgeneration fast-response LCD-TVs possible and free from image blurring in conjunction with an impulsive driving scheme.
