In recent years, a high-quality video input device has been generalized, and a central control system capable of simultaneously viewing video input in real time has become an essential element. At this time, there are attempts to access through the web without installing the program separately. However, if multiple high-quality videos are simultaneously viewed through the web browser, the web browser is terminated by force. In this paper, we propose a web-based HLS(HTTP Live Streaming) multi-view system for real-time high-definition video. We have reconstructed the multi-view screen as a screen by transcoding and implemented a system that can monitor multiple video inputs through a web browser on the fly without using security vulnerability ActiveX.

In this paper, we propose a time-frequency domain reflectometry (TFDR) based measurement method for localizing concentric neutrals corrosion on live underground power cable. It consists of two inductive couplers which can transmit the reference signal into live underground power cable and measure the reflected signals from the impedance discontinuities of concentric neutrals corrosion. In order to compensate the dispersion of the measured reflected signal via inductive coupler, an equalizer based on Wiener filtering is designed. To improve the localizing performance of concentric neutrals corrosion in the vicinity of the measurement point, the reference signal is removed from the measured reflected signals. The localization performance of the proposed method is verified by the concentric neutrals corrosion localization experiment.

This paper researches the algorithm, whose materiality and expressiveness can be obtained through live coding. Live coding is an improvised genre of music that generates sounds while writing code in real time and projecting it onto a screen. Previous studies of live coding have focused on the development environment to support live coding performance effectively. However, this study examines the aesthetic attitude immanent in the realization of the algorithm through analyzing mostly used languages such as ChucK, Impromtu, and the visualization of live code and cases of "aa-cell" and "slub" performance. The aesthetic attitudes of live coding performance can be divided into algebraic and geometric attitudes. Algebraic attitudes underline the temporal development of concepts; geometric attitudes highlight the materialization of the spatial structure of concepts through image schemas. Such a difference echoes the tension between conception and materiality, which appears in both conceptual and concrete poetry. The linguistic question of whether conception or materiality is more greatly emphasized defines the expressiveness of the algorithm.

This experimental work was carried out to know the best method in producing the root stock effectively. The major experimental work was carried out by using Kairyo-Nezumigaeshi, and the comparative works were carried out by using Ichi-Hei, Kairyo-Nezumigaeshi, Ro-Soh, Yongchon-Chuwoo and Suwon No. 4. Results obtained from the test are as follows. 1. The larger size of the branch burried, the better live ratio and the quality of the sapling was found, and there was no significant difference between the top part and bottom part of the branch from the point of view of the ratio, but it was found that the top part showed better live ratio and quality. Mean time there was no difference in live ratio between the two sprouts root-stock type and the three sprouts root-stock type. 2. When the live ratio and sapling quality was compared from the aspect of the new root development, the heavy and medium developed root type showed better result than the poor developed one. 3. For the ambushing depth test of the root-stock, the root-stock which was painted with paraffin on the top and exposed in the air was found to have best live ratio. Mean time, even though paraffin was not painted all the top of the root-stock, the one which was exposed the top of it or the one ambushed with thin soil layer, showed better live ratio than the one deep ambushed. 4. There was difference for the live ratio between the perpendicularly ambushed root-stock and the lied ambushed mot-stock, but the former method showed better sapling quality. 5. The soil nature did not show any difference for the live ratio between the sand loam and clay loam, but the former one showed better sapling quality. 6. There was no difference live ratio between the mulberry varieties, but Yongchon-Chuwoo showed best sapling quality. 7. The grafted sapling production cost was 2.30 won and cattage sapling cost was 1.61 won.

Currently, in China, mobile live broadcasts are more popular compared to online live broadcasts. Accordingly, this research focused on Wanghong, SNS's flagship live broadcasting app. In other words, Wanghong refers to an internet celebrity who acts online on social network services (SNS) influencing many other people. This study specifically focused on one social network service and conducted a study on live app users. The study first analyzed the quality factors of an SNS to users using China's live app. Secondly, the research investigated in finding out the impact of quality on the satisfaction of live app users and how this affects the live app user's satisfaction on their intention of continuous use. Studies have shown that information quality, system quality, and social quality among SNS quality have a positive influence on live app user satisfaction. However, the quality of service and the quality of emotion was rejected by the hypothesis. Throughout this study, we hope to create an app that allows users to share more satisfying mobile images, thereby establishing various episodes holding beautiful places of their life on a real-time basis. It is hoped that live broadcasting businesses will spread a significant impact around the world. Finally, in the future, research on the study of collective comparison between Korea and China on SNS is believed to be meaningful.

In this paper, we developed the hardware GPS signal generator for generating a satellite navigation signal synchronized with Live GPS signal signals and analyzed the performance of signal genterator thorough the experiment For a hardware implementation of the GPS navigation signal synchronous generator, the GPS module may receive a GPS signal in order to generate the same signal as the operation that is transmitted from the current GPS satellite and the synchronized time information and the GPS satellites using the Novatel Inc. OEMStar.In. For generating the GPS synchronization signal, the GPS navigation signal generator was adjusted to a reference clock using the GPS clock synchronous information provided by the GPS receiving module and GPS signals also generated in consideration of the delay of the internal hardware of the generator. In this paper, we analyzed the effect of the receiver via the signal switching between Live GPS signal and generates a signal to measure the performance of the GPS navigation synchronization signal generator. It was confirmed that by the seamless operation of the signal even the moment that the switching of the generated signal from Live GPS signal has occurred through experimentation.

This study aimed to investigate the difference of X-ray exposure by comparing and analyzing absorbed dose according to changes in the number of frames in coronary angiography, also depending whether the zoom mode is FOV enlargement or Zoom Live. Moreover, for appropriate frame selection measures for examination, including the effect of frame change on the image quality, were sought by measuring the noise strength expressed by the standard deviation (SD), the signal to noise ratio (SNR) and contrast to noise ratio (CNR). The study was conducted with an anthropomorphic phantom on an angio-system. The linear relationship between the frame rate and the radiation dose was evident. On the contrary, the indices of image quality (SD, SNR, and CNR) were almost constant irrespective of the number of frames. The difference depending on the zoom mode was not statistically significant for DAP, air kerma, and SD (p > 0.05). However, SNR and CNR were statistically different between FOV enlargement and Zoom Live. In conclusion, since the image quality was not degraded significantly with the decreasing frame rate from 30, 15, to 7.5 f/s and the radiation dose evidently decreases in almost exactly linear proportion to the decreasing frame rate, the number of frames per second needs to be maintained as low as reasonably achievable. As for the dependence on the zooming mode, the Live Zoom mode showed statistically significant improvement in the image quality indices of SNR and CNR and it justifies active use of the Live Zoom mode which enables real-time image enlargment without additional radiation dose.
