위진커(Jinke Yu),이상윤(Sang Yoon Lee) 한국엔터테인먼트산업학회 2018 한국엔터테인먼트산업학회 학술대회 논문집 Vol.2018 No.11
본 연구는 애니메이션 “Escape”에 나타난 사운드의 역할을 내러티브 공간의 관점으로 분석하였다. 이 작품은 배경 공간의 디자인을 사운드로 표현하는 특징을 가지고 있다. 이 작품의 영상 공간을 내러티브의 관점으로 생각해보면, 이는 실제적인 공간과 상상 속의 공간인 가상적 공간으로 나눌 수 있다. 이처럼 작품에 나타나는 공간의 차원은 배경음악과 음향효과의 구별로 나타내고 있으며, 화면에서 배경공간으로 드러나지 않는 것을 청각적인 음향으로 표현하고 있다. 또한 음향효과가 서로 상반된 공간을 이어주는 역할을 수행하기도 하였다. 이 작품의 사운드는 작품의 내러티브 공간을 구성하고 이해하는데 있어서 매우 중요한 요소로 작용하였다. This study analyzed the role of the sound in the animation "Escape" from the viewpoint of the narrative space. This work has the characteristic of expressing the design of the background space by the sound. Considering the visual space of this work as a perspective of narrative, it can be divided into actual space and imaginary space. The dimension of the space in the work is represented by the distinction between the background music and the sound effects, and the one which is not revealed as the background space on the screen is expressed by the auditory sound. In addition, the sound effects performed a role in connecting the contrasted spaces. The sound of this work also performed an important role in constructing and understanding the narrative space of the work.
Image Forgery Detection Algorithm Based on Non Sampling Wavelet Transform and Zernike Moments
Xiao Jinke 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.2
In order to solve such problems as poor robustness and low detection accuracy in the present copying & pasting forgery detection algorithm, an image copying & moving forgery detection algorithm based on non-sampling wavelet transform (undecimated wavelet transform, UWT) coupling with Zernike moments is proposed in this article. Firstly, the non-sampling wavelet transform is adopted to decompose the input image into approximation coefficient LL and detail coefficient HH to obtain the similarity and the diversity of the image blocks; secondly, the overlapped blocks are divided to calculate the sub-block interval of the image; thirdly, the sub-blocks are ordered and classified according to LL similarity and HH diversity; fourthly, Zernike moments are introduced to construct the distance matrix for image feature matching and image forgery detection. The experiment shows: the algorithm proposed thereby has good translation invariance and amplitude rotation invariance, good post-processing resistance performance, high detection accuracy, low false negative rate and low false positive rate.
Adaptive V1-MT model for motion perception
( Shuai Li ),( Xiaoguang Fan ),( Yuelei Xu ),( Jinke Huang ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.1
Motion perception has been tremendously improved in neuroscience and computer vision. The baseline motion perception model is mediated by the dorsal visual pathway involving the cortex areas the primary visual cortex (V1) and the middle temporal (V5 or MT) visual area. However, few works have been done on the extension of neural models to improve the efficacy and robustness of motion perception of real sequences. To overcome shortcomings in situations, such as varying illumination and large displacement, an adaptive V1-MT motion perception (Ad-V1MTMP) algorithm enriched to deal with real sequences is proposed and analyzed. First, the total variation semi-norm model based on Gabor functions (TV-Gabor) for structure-texture decomposition is performed to manage the illumination and color changes. And then, we study the impact of image local context, which is processed in extra-striate visual areas II (V2), on spatial motion integration by MT neurons, and propose a V1-V2 method to extract the image contrast information at a given location. Furthermore, we take feedback inputs from V2 into account during the polling stage. To use the algorithm on natural scenes, finally, multi-scale approach has been used to handle the frequency range, and adaptive pyramidal decomposition and decomposed spatio-temporal filters have been used to diminish computational cost. Theoretical analysis and experimental results suggest the new Ad-V1MTMP algorithm which mimics human primary motion pathway has universal, effective and robust performance.
Jasmine tea extract enhances human retinal pigment epithelial cells survival after UVB irradiation
Shang Hu,Guo Yaling,Wu Liangyu,Lin Jinke 한국응용생명화학회 2023 Applied Biological Chemistry (Appl Biol Chem) Vol.66 No.-
To examine the protecting effect of jasmine tea extract (JTE) against ultraviolet B (UVB) induced damage on human retinal pigment epithelial (RPE) cells, the RPE cells were subjected to UVB exposure and sequential JTE administration. The cell viability, intracellular reactive oxygen species (ROS), and apoptosis were determined by MTT, 2ʹ,7ʹ-dichlorodihydrofluorescein diacetate and flow cytometer assays, respectively. Further, the cells treated with UVB irradiation and sequential JTE administration were subjected to RNA-sequencing analysis in order to identify genes and pathways involved in the UVB-induced damage and JTE protecting mechanisms. The results showed that JTE effectively attenuated the UVB-induced cell injury by reducing the excessive intracellular ROS generation, and inhibiting the expression of apoptotic genes such as Bax, Caspase-3/9. This finding may offer a promising candidate for the prevention of UVB exposure related eye diseases.

In high diversity node situation, single-channel MAC protocols suffer from many collisions. To solve this problem, the research of multichannel MAC protocol has become a hotspot. And the cyclic quorum-based multichannel (CQM) MAC protocol outperformed others owing to its high frequency utilization. In addition, it can avoid the bottleneck that others suffered from and can be easily realized with only one transceiver. To obtain the accurate performance of CQM MAC protocol, a Markov chain model, which combines the channel hopping strategy of CQM protocol and IEEE 802.11 distributed coordination function (DCF), is proposed. The metrics (throughput and average packet transmission delay) are calculated in performance analysis, with respect to node number, packet rate, channel slot length and channel number. The results of numerical analysis show that the optimal performance of CQM protocol can be obtained in saturation bound situation. And then we obtain the saturation bound of CQM system by bird swarm algorithm (BSA). Finally, the Markov chain model and saturation bound are verified by Qualnet platform. And the simulation results show that the analytic and simulation results match very well.

Brucella is an intracellular pathogen that invades a host and settles in its immune cells; however, the mechanism of its intracellular survival is unclear. Modification of small ubiquitin-related modifier (SUMO) occurs in many cellular activities. E2 conjugating enzyme 9 (Ubc9) is the only reported ubiquitin-conjugating enzyme that links the SUMO molecule with a target protein. Brucella's intracellular survival mechanism has not been studied with respect to SUMO-related proteins and Ubc9. Therefore, to investigate the relationship between Brucella melitensis 16M and SUMO, we constructed plasmids and cells lines suitable for overexpression and knockdown of SUMO1 and Ubc9 genes. Brucella 16M activated SUMO1/Ubc9 expression in a time-dependent manner, and Brucella 16M intracellular survival was inhibited by SUMO1/Ubc9 overexpression and promoted by SUMO1/Ubc9 depletion. In macrophages, Brucella 16M-dependent apoptosis and immune factors were induced by SUMO1/Ubc9 overexpression and restricted by SUMO1/Ubc9 depletion. We noted no effect on the expressions of SUMO1 and Ubc9 in B. melitensis 16M lipopolysaccharide-prestimulated mouse RAW264.7 macrophages. Additionally, intracellular survival of the 16MΔVirB2 mutant was lower than that of Brucella 16M (p < 0.05). VirB2 can affect expression levels of Ubc9, thereby increasing intracellular survival of Brucella in macrophages at the late stage of infection. Collectively, our results demonstrate that B. melitensis 16M may use the VirB IV secretion system of Brucella to interact with SUMO-related proteins during infection of host cells, which interferes with SUMO function and promotes pathogen survival in host cells.
A Sound Activity Monitor with 96.3 μs Wake-up Time and 2.5 μW Power Consumption
Jinkee Kim,Yunyoung Jang,Jong Pal Kim 대한전자공학회 2023 Journal of semiconductor technology and science Vol.23 No.6
A novel low power sound activity monitor (SAM) for fast wake-up is presented. SAM is used for low power consumption of intelligent microphones. An intelligent microphone that responds to user voice commands should operate for 24 hours. Normally, the microphone remains in low power mode when there is no external sound input. While the SAM detects external sound input, the SAM changes from low power mode to normal power mode and the microphone remains in normal power mode. The wake-up time from low power mode to normal power mode should be as short as possible so that user commands are not lost. In addition, power mode switching must be prevented from malfunctioning due to artifacts generated when changing between power modes. Low power and wake-up characteristics are improved by simplifying the SAM structure, and the decision logic is designed to be robust against power switching artifacts. The proposed SAM was designed and fabricated based on a CMOS 0.18 μm process, and its features and performance were measured. The SAM operating at 1.8V consumes 2.5 μW power, and the fast wake-up performance of 96.3 μs is measured.
