In this work, we considered a compressed-sensing (CS)-based image deblurring scheme with a total-variation (TV) regularization penalty for improving image characteristics in digital tomosynthesis (DTS). We implemented the proposed image deblurring algorithm and performed a systematic simulation to demonstrate its viability. We also performed an experiment by using a table-top setup which consists of an x-ray tube operated at $90kV_p$, 6 mAs and a CMOS-type flat-panel detector having a $198-{\mu}m$ pixel resolution. In the both simulation and experiment, 51 projection images were taken with a tomographic angle range of ${\theta}=60^{\circ}$ and an angle step of ${\Delta}{\theta}=1.2^{\circ}$ and then deblurred by using the proposed deblurring algorithm before performing the common filtered-backprojection (FBP)-based DTS reconstruction. According to our results, the image sharpness of the recovered x-ray images and the reconstructed DTS images were significantly improved and the cross-plane spatial resolution in DTS was also improved by a factor of about 1.4. Thus the proposed deblurring scheme appears to be effective for the blurring problems in both conventional radiography and DTS and is applicable to improve the present image characteristics.

This Paper proposes an effective SoC hardware architecture implementing a VDP for Full HD TVs. The proposed architecture makes real time video processing possible with supporting efficient bus architecture and flexible interface. Video IP cores in the VDP are designed to provide a high quality of improved image enhancement function. The Avalon interface is adopted to guarantee real-time capability to IPs as well as SoC integration. This leads to reduced design time and also enhanced designer's convenience due to the easiness in IP addition, deletion, and revision for IP verification and SoC integration. The embedded software makes it possible to implement flexible real-time system by controlling setting parameter details and data transmitting schemes in real-time. The proposed VDP SoC design is implemented on Cyclon III SoPC platform. The experimental results show that our proposed architecture of the VDP SoC successfully provides required quality of Video image by converting SD level input to Full HD level image.

This study examined the causal relationship between the Chinese preference for Korean cultural products (Korean talent, K-pop songs, TV dramas, and movies), for Korean fashion products, and their purchase intentions. The relationship between the Korea's national brand image and Chinese fashion leadership with the three variables was investigated. Data was collected from 580 Chinese in Dalian, China. The data was analyzed using frequency, correlations, reliability, and AMOS for path analysis. The results of this study were as follows. First, the preference for Korean talent, K-pop songs, TV dramas, movies, and fashion products showed that the Chinese had a positive response and the degree of preference for each item was similar. Second, the Chinese preference for Korean talent, movies, and TV dramas significantly influenced the preference for Korean fashion products. In addition, the Chinese preference for Korean fashion products significantly influenced the purchase intentions of Korean fashion products. Third, the Chinese preference for Korean talent and fashion products had a significant relationship with their fashion leadership. In addition, the preference for Korean talent, movies, TV dramas, K-pop songs, fashion products, and purchase intentions had the same positive relationship with Korea's national brand images. This study examined from a structural aspect how the preference of Korean intangible cultural products affected the purchase intention of Korean fashion products. This study explored that the preference for Korean cultural products transcended the popularity of the Korean popular culture with a subsequent national industrial and economic ripple effect that improved the national brand image.

A DMB in an ubiquitous age means that every one can share informations anytime anywhere through 'his own TV' or 'TV in his own hands'. A DMB of digital broadcastings makes the most use of informations through ubiquitous. But it has several problems just owing to retransferring existing broadcast programs in contents. So hereafter, DMB broadcasting must be produced with contents suiting its properties. After all, it is important to analyze exactly properties and service fields of medium of DMB to make an establish production direction of its contents. This paper analyzes such properties and presents overall image-contents production direction. This includes appropriate program developments and visual expressions through proper running time, camera angle and walking. The contents harmonized with its properties will give more familiarities to DMB users and it will be a new culture. In the end, it is expected that a share of DMB audience will be more higher.

Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.

Ubiquitous computing technology is emerging as information technology advances. In line with this, a number of studies are being carried out to increase device miniaturization and user convenience. Some of the proposed devices are user-friendly and uncomfortable with hand-held operation. To address these inconveniences, this paper proposed a virtual button that could be used in watching television. When watching a video on television, a camera is installed at the top of the TV, using the fact that the user watches the video from the front, so that the camera takes a picture of the top of the head. Extract the background and hand area separately from the filmed image, extract the outline to the extracted hand area, and detect the tip point of the finger. Detection of the end point of the finger produces a virtual button interface at the top of the image being filmed in front, and the button activates when the end point of the detected finger becomes a pointer and is located inside the button.

Can law be combined with television entertainment programs? This paper explores the ways in which law systems and law culture are reflected in and reflect the television legal series. TV legal series, such as legal dramas and infotainment shows, provide platforms for the audiences, who otherwise have few opportunity in real life, to engage with legal systems in societies. Adopting loosely dramatized reality programs, these legal series not only entertain and inform audiences but also educate citizens. This paper combines analyses of theoretical debates on law and television with analysis of TV text. The result shows that , dramatized enactment based on true stories and criminal cases, may have an important ideological role in which fictionalized dramas mask the hard realities and authoritative legal systems. By doing so, TV legal shows play their roles not as mere symbolic representation but as powerful institutions that construct the image of law and reality.
