In general wireless power transfer systems (WPTSs), power transfer is controlled by the wireless communication between a transmitter (Tx) and a receiver (Rx). However, WPTS is difficult to apply in electronic products that do not have batteries, such as TVs. A WPTS with resonators based on a transformer of LLC series resonant converter is proposed in this study to eliminate wireless communication units between a Tx and an Rx. The proposed system operates at the boundary of the resonance frequency, and the required power can be stably supplied to authorized devices even though some misalignment occurs. Moreover, standby power standards for the electronic product can be satisfied.

The area of discourse analysis has long neglected the value of images as a semiotic resource in communication. This paper suggests that like language, images are rich in meaning potential and are governed by visual grammar structures which can be utilized to decode the meanings of images. Employing a theoretical framework in visual communication, two digital images are examined for their representational and interactive dimensions and the dimensions' relation to the magazine advertisement genre. The results show that the framework identified narrative and conceptual processes, relations between participants and viewers, and symbolic attributes of the images, which all contribute to the sociological interpretations of the images. The identities and relationships between viewers and participants suggested in the images signify desirable qualities that may be associated to the product of the advertiser. The findings support the theory of visual grammar and highlight the potential of images to convey multi-layered meanings.

Visible light communication technology is being studied and developed in various ways due to advantages such as high transmission speed, excellent positioning and higher security. However, existing visible light communication systems have difficulties in entering the market because they use special transmitters and receivers. We will overcome the difficulty if we develope a VLC system that uses a conventional LED light as a transmitter and a smartphone camera as a receiver. What matters is that LED lights include a scatter filter to prevent glareness for human eyes, but the existing VLC(Visual Light Communication) method can not be applied. In this paper, we propose a method to encode data with On / Off patterns of LEDs in the lighting with $M{\times}N$ LEDs. We defined parameters like L-off-able and K-seperated to facilitate the recognition of On / Off patterns in the diffused Lights. We conducted experiments using an LED lighting and smart phones to determine the parameter values. Also, the maximum transmission rate of our encoding technique is mathematically presented. Our encoding scheme can be applied to indoor and outdoor positioning applications or settlement of commercial transactions.

China's intangible cultural heritage at the national level amounts to more than 1,500 species, and it is also the country with the largest number of items on UNESCO's intangible cultural heritage list, so the intangible cultural heritage of the country and mankind is very much treasured and cared for. However, with the development of the times, many intangible cultural heritages are facing a dilemma due to the problem of a single form of communication. However, at the same time, the efficient and convenient way of information visualization provides innovative ideas and new opportunities for the visual communication of Chinese intangible cultural heritage. This paper examines the formal characteristics of infographic visual expression on the theoretical basis of books and related papers and analyzes the application cases and advantages of infographics in the communication of Chinese intangible cultural heritage in the context of the present era. It aims to explore a fast and novel visual presentation method for the communication of Chinese intangible cultural heritage through infographic design methods, to promote the inheritance and development of Chinese intangible cultural heritage in the new era.

디지털미디어 환경에서 메시지는 언어적 표현이외에도 다양한 영상으로 의미를 표현하고 인터페이스에서 이와 같은 메시지의 표현이 나타난다. 인터페이스에서 이러한 메시지 구성의 변화는 인간에게 메시지의 수용을 수동적 수용에서 능동적 수용으로 변화시키고 있다. 최근 개발된 인터페이스는 사용자로 하여금 다양한 시각적 효과를 경험하게 하고 있다. 인터페이스에서 전해지는 의미의 전달은 모호하지만 사용자는 감각적으로는 강한 인상을 받는다. 이와 같은 다양한 비언어적인 메시지 영상 표현을 인터페이스를 통해 경험하고 있다. 비언어적 메시지 영상들은 사용자에게 어떤 메시지를 전하고 있지만 사용자마다 받아들이는 해석은 다르다. 그 이유는 비언어적 메시지 영상은 의사소통에 있어서 개념화되지 않아 사람마다 의미의 차이를 보이고, 사용자에게 인터페이스의 사용 경험에 있어서 즉흥적인 시각 경험을 주기 때문이다. 의미는 모호하지만 감각을 지극히는 즉흥적이고 화려한 영상 효과는 디지털 미디어 환경에서 흔히 나타나는 현상이 되었고 일상화되며 즐기고 있다. 비언어적 메시지 영상 표현은 아직 개념화되지 않은 커뮤니케이션의 시각적 표현의 확장이고, 나아가 사용자들에게 제공되는 또 하나의 메시지가 될 수 있다. 따라서 다양한 시각표현을 제공하는 인터페이스(GUI)에서는 시각적 감각만을 통해 수용하기 보다는 다감각적인 분산적 지각으로 수용한다.

21st century is called digital and information era. The visual communication becomes more important than any other centuries. Visual communication design has been represented in varied images from ancient society up until the present time. Especially graphic design, which has experienced artistic upheaval from modernism and postmodernism, has been enabled to deliver messages in a more developed and sensuous appearances. Deconstructionist design wasn't well received by modernism, an advocate of practicality and effectiveness; however, as the beginning of subsequent postmodernism, it started to earn a warm welcome from a number of designers. Postmodernism made it possible for deconstruction to be a new paradigm appreciating neutral respect for varied expressions and designers' idiosyncrasy. Corresponding to this new trend, Edward Fella published his artwork 'Letters on America', which introduced a variety of vernacular design works in America. It was the result of years of research, and included materials which were not something completely new to field of communication design but rather symbolic, deconstructive images available everywhere around us. Deconstruction broke away from the previous modernism's unity and standards, and sought to achieve a new tensional deliverance. As a consequence, images were created in destructive and incomplete forms. Graphic design also complied with this new code and its advent fascinated the artists in the fields of advertising, editorial and poster designs. This paper contends that contemporary graphic design still maintains a deconstructive representation, examines its locality in design works from an aesthetic viewpoint, and researches theoretical approaches to deconstructionist and case studies conducted domestically. There has been incessant critical contradiction in terms of the heritage of deconstruction. I would like to present you with a moment in which you can struggle to decide whether it is a result of an effort to get away from modernism or an offspring of postmodernism.

The 21st century is the age when a sensational image has more explanatory power and can deliver a more powerful message than a message consisting of logical thinking. Powerful visual images create a big impact on many people throughout the world, overcoming linguistic barriers and even replacing language as a means of communication. In the fashion field, the concept and power of visual images within the new multimedia of the 21st century are becoming increasingly important. In recent years, other than the above methods, videos, movies and animation features have been produced directly to enhance visual effects and attempts are increasing to use these new tools as communication methods. This study focuses on animation contents that have been used in the fashion industry to overcome prejudice of luxury international brands that feature images that emphasize value, quality and heritage. The purpose of this study is to focus on the specific character of fashion animation in order to overview the concept of 21st video fashion communication and to show how the collection concept that includes color and detail places an emphasis on visual images. Analysis of previous research, theoretical research through literature and case study on Prada fashion animation led to the following conclusion. The common features of two different Prada fashion animation show that both animation have the following features in common : realism, dramatic impact and convergence for expression methods, and creativeness, hybrid and a happy ending for contents. Beginning with this study, I believe that various angles of interest and concern about communication in the fashion world, which is a social and cultural phenomenon that changes rapidly, can be will be looked at and learned from.

Repetition of landing with visual control in sports and training is common, yet it remains unknown how landing with visual control affects postural stability and lower limb kinetics. The purpose of this study was to test the hypothesis that landing with visual control will influence on lower limb control for intrinsic dynamic postural stability. Kinematics and kinetics variables were recorded automatically when all participants (n=10, mean age: 22.00±1.63 years, mean heights: 177.27±5.45 cm, mean mass: 73.36±2.80 kg) performed drop landings from 30 cm platform. Visual control showed higher medial-lateral force, peak vertical force, loading rate than visual information condition. This was resulted from more stiff leg and less time to peak vertical force in visual control condition. Leg stiffness may decrease due to increase of perturbation of vertical center of gravity, but landing strategy that decreases impulse force was shifted in visual control condition during drop landing. These mechanism explains why rate of injury increase.
