Yiting Wang,김세범 사단법인 인문사회과학기술융합학회 2019 예술인문사회융합멀티미디어논문지 Vol.9 No.1

The purpose of this paper is to clarify the formation process of online gamers' satisfaction and the moderating effect of network involvement in this process. For the purpose we collected data from 267 online gamers via a web-based questionnaire survey in China. With the help of researches up to the present, we proposed a research model which consist of four latent variables such as E-service quality, product factor, perceived value and customer satisfaction. Through structural equation model analysis, we found that: first, E-service quality and product factor have positive effect on the customer perceived value, and E-service quality has a greater impact on customer satisfaction; second, E-service quality has a significant effect on perceived value, and it is notable that the effect is bigger for the high-involvement group than low-involvement group; third, perceived value not only direct affect customer satisfaction, but also plays an important intermediary role in the formation of customer satisfaction.

강문(薑文)감독의 음향 스타일 연구 - 영화 <햇빛 쏟아지던 날들(陽光燦爛的日子)> <양자탄비(讓子彈飛)> <히든맨(邪不壓正)>을 중심으로

왕이팅 ( Wang Yiting ) 한국영화교육학회 2023 영화교육연구 Vol.17 No.3

유성영화가 탄생한 이래 그에 수반되는 영화음악은 영화 특유의 미학적 의미를 부여해 왔다. 현대 미디어 산업의 급속한 발전으로 인해 시청각에 대한 사람들의 요구 사항이 점점 높아지고 있으며 단순한 음성 구성은 더 이상 사람들의 시청각 요구를 충족시킬 수 없습니다. 전통적인 관념에서 영화는 보기 위한 것이기 때문의 화면은절대적인 주인공이고, 소리는 전적으로 화면을 위한 것이다. 하지만 지금은 시청각 언어 등소리와 화면에 대한 논의가 중요시되면서 영화 속에서 소리의 중요성이 인식되고 있다. 영화음악은 오랜 발전의 세월을 거쳐 영화예술에 없어서는안 될 부분으로 발전해 왔다. 보통 우리가 영화를 볼 때 스토리텔링에서 느끼는 모든 것은 스크린에서만 나오는 것이 아니라 스토리텔링과 함께 나오는 음악이다. 영화는 음화와 그림을 모두 갖춘 예술이며, 영화 사운드트랙의 질은 영화 화면 못지않게 중요하며, 영화의 성패와 직결된다. 강문감독은 28년간 총 6편의 작품을 연출했다. 감독님의 작품에서 자신의 스타일과 특색이 잘 표현되어 있다. 작품에 대한 구상은 지극히 교묘하고, 인물의 짜임새와 성격을 잘 그려내는데, 그의 작품에서는 어떤 인물, 어떤 대사도 흥미진진하다. 강문감독의 작품은 목소리가 개성이 참신하고 리듬이 밝고 코믹하며 국제화된 특징이 있다. 영화 속 음악은 대담할 뿐만 아니라 주제 배경에도 잘 맞는다. 해외 거장들과 협업해 만든 음악이든, 고전적인 음악을 활용한 작품이든, 영화 작품에서의 활용은 최고의 접점을 찾았다. 사운드트랙은 단순히 음악으로 분위기를 띄우는 것이 아니라 영화의 의미를 더하고, 같은 음악을 다른 화면에 적용하면 은유적인 효과를 내 관객의 사고를 유발한다. 이 글은 장원 감독의 <햇빛 쏟아지던 날들>, <양자탄비>, <히든 맨>의 세 작품을 중심으로 영화의 음악 스타일을 연구하고 영화의 음악적 특성을 요약 및 평가하여 영화 음악 이론에 일정한 참고와 시사점을 제공하고 예술 창작자와 영화 음악 창작자에게 더 많은 사고와 조언을 제공한다. Since the birth of the sound film, the accompanying film music has injected the unique aesthetic significance into the film.Because of the rapid development of modern media industry, people's requirements for audiovisual aspects are getting higher and higher, simple audio configuration can not meet people's audiovisual needs.In the traditional sense, movies are used to watch, so the picture is the absolute protagonist, and the sound is entirely for the picture.But now the discussions about sound and picture, such as audio-visual language and audio-visual art, are being paid attention, and people realize the importance of sound in movies.After a long time of development, film music has gradually developed into an indispensable part of film art.Usually, when we watch a movie, everything we feel from the storyline is not just the screen, but the music that accompanies the storyline.Film is an art of both sound and painting. The quality of film score is as important as the picture of film, which is related to the success or failure of film. Director Kang Moon has made six films in 28 years of directing.In his director's work, he fully expressed his own style and characteristics.The idea of the work is extremely ingenious, and the arrangement and characterization of the characters are perfect. In his work, any character, any line is interesting.Director Jiang Wen's work has a novel sound, bright rhythm, full of comedy, and international characteristics.The music in the film not only uses boldness, but also fits the theme background.Whether it is the music produced jointly with foreign music masters or the use of classical music works, the application in the film works has found the best fit.The film score not only embellishes the mood with music, but also expands the meaning of the film. The same music is applied to different pictures, and reaches the effect of metaphor, which causes the audience to think. Based on Jiang Wen's three works, Sunshine Day, Let the Bullet Fly, Error Uncompressed, this paper studies the musical style of his films, and evaluates the musical application features of his films.

Diff erences in the Acoustic Emission Characteristics of 345 MPa Normal-Strength Steel and 460 MPa High-Strength Steel

Yiting Yang,Yan Wang,Kehao Li 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.1

This study characterized 345 MPa normal-strength steel (NSS) and 460 MPa high-strength steel (HSS) with the acoustic emission (AE) technique. Pencil lead break (PLB) and tensile tests were performed, and the generated AE signals were recorded. The AE signals from the PLB tests were converted into the frequency and time-frequency domains via a fast Fourier transform (FFT) and wavelet transform. The AE signals generated during the tensile process were divided into four stages for analysis. The AE parameters, such as the counts, amplitude, hit and duration, were extracted from the signals. An FFT was conducted to obtain the features of frequency spectrum at each stage. The comparisons revealed the similarities and diff erences in the AE characteristics between the two steels. It was found that the energy of the AE signals for the 460 MPa HSS was less overall than that of the 345 MPa NSS. The analysis results indicated that the AE technique is a method that can potentially be used to distinguish the two steels, and additional studies for accurate identifi cation are needed. As 460 MPa HSS is being widely used but related AE studies are limited, this study provides data for additional investigations of the damage in HSS structures with the AE method.

Yiting Xu,Jiamei Huang,Yuntong Li,Meijie Wang,Ying Cao,Conghui Yuan,Birong Zeng,Lizong Dai 한국고분자학회 2017 Macromolecular Research Vol.25 No.8

A novel zwitterionic hybrid amphiphilic copolymer containing polyhedral oligomericsilsesquioxane (POSS), and poly(methacrylate isobutyl POSS)-b-poly (3-dimethyl(methacryloyloxyethyl) ammonium propane sulfonaten-co-2-(diethylamino) ethyl methacrylate-co-styrene) (PMAiBuPOSS-b-P(DMAPS-co-DMAEMAco- St)), was prepared by the ring open reaction of 1, 3-propane sultone with tertiary amine on the precursor polymer. This hybrid copolymer could self-assemble into spherical micelle with a relatively narrow size distribution. The micelle size exhibited a great dependence on pH, as the size of the micelles was of evidently decreases with the increase of the pH value. Controllable release of pyrene from the micelles was investigated by fluorescent emission spectra. Micelles with more zwitterionic units would lead to less pyrene release and longer equilibrium time. The protein adsorption resistance of the micelles was tested by mixing them with fetal bovine serum. The antifouling ability was improved by increasing the number of zwitterionic units as well as decreasing the number of DMAEMA units. This novel hybrid amphiphilic random copolymer with the pH-responsive and anti-protein-fouling ability, can be potentially used for drug carriers for controlled release.

Huilan Ye,Yiting Wu,Ziqing Zhong,Shichang Sun,Jia Chen,Weiming Zhou,Ibrahim Lawan,Liwei Wang,Zhanhui Yuan 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.4

A Bi6O6(OH)3(NO3)3·1.5H2O (BBN)/Bi2O2CO3 (BOC) heterojunction was designed for the first time via afacile hydrothermal method. The photocatalytic performance of catalysts was evaluated by degrading Rhodamine B(RhB) under simulated solar light irradiation. It was found that the degradation rate of RhB by 25 wt%BBN/BOC wasdramatically increased about 1.5 and 4.7 times compared with that of pure BOC and BBN, respectively. The enhancedphotocatalytic performance migth be attributed to the effective separation of photoinduced electron-hole pairs, benefitingfrom the construction of heterojunction. Furthermore, the mechanism upon BBN/BOC composites photocatalystwas investigated, expecting this work will bring new insight into the theoretical study and application of semiconductorsmaterials.

Yan Rui,Wang Kai,Tian Xiaodong,Li Xiao,Yang Tao,Xu Xiaotong,He Yiting,Lei Shiwen,Song Yan 한국탄소학회 2020 Carbon Letters Vol.30 No.3

Heteroatoms in situ-doped hierarchical porous hollow-activated carbons (HPHACs) have been prepared innovatively by pyrolyzation of setaria viridis combined with alkaline activation for the frst time. The micro-morphology, pore structure, chemical compositions, and electrochemical properties are researched in detail. The obtained HPHACs are served as outstand�ing electrode materials in electrochemical energy storage ascribe to the particular hierarchical porous and hollow structure, and the precursor setaria viridis is advantage of eco-friendly as well as cost-efective. Electrochemical measurement results of the HPHACs electrodes exhibit not only high specifc capacitance of 350 F g−1 at 0.2 A g−1, and impressive surface specifc capacitance (Cs) of 49.9 μF cm−2, but also substantial rate capability of 68% retention (238 F g−1 at 10 A g−1) and good cycle stability with 99% retention over 5000 cycles at 5 A g−1 in 6 M KOH. Besides, the symmetrical supercapacitor device based on the HPHACs electrodes exhibits excellent energy density of 49.5 Wh kg−1 at power density of 175 W kg−1 , but still maintains favorable energy density of 32.0 Wh kg−1 at current density of 1 A g−1 in 1-ethy-3-methylimidazolium tetrafuoroborate (EMIMBF4) ionic liquid electrolyte, and the excellent cycle stability behaviour shows the nearly 97% ratio capacitance retention of the initial capacitance after 10,000 cycles at current density of 2 A g−1. Overall, the results indicate that HPHACs derived from setaria viridis have appealing electrochemical performances thus are promising electrode materi�als for supercapacitor devices and large-scale applications.

Luo Jia,Yang Yiting,Liao Kun,Liu Bin,Chen Ying,Shen Linyuan,Chen Lei,Jiang An’an,Liu Yihui,Li Qiang,Wang Jinyong,Li Xuewei,Zhang Shunhua,Zhu Li 아세아·태평양축산학회 2020 Animal Bioscience Vol.33 No.8

Objective: The QingYu pig is well known for its excellent meat quality attributes in Sichuan province, China. In order to improve its production efficiency, the determination of genetic factors contributing to quantifiable economic traits of livestock is important. Moreover, the cross-breeding of QingYu pigs with western breeds possessing strong growth attributes is an efficient way to improve the performance of this breed. Methods: Here, the genetic parameters of several important reproductive traits of QingYu pigs were estimated, include total number born (TNB), number born alive, litter birth weight, individual birth weight, number of piglets weaned, litter weaning weight, and individual weaning weight. The data was analyzed using the ASReml 3.0 software (NSW Inc., Sydney, Australia). Furthermore, the effects of crossing Berkshire with QingYu (BQ) pigs on carcass and meat quality traits, as well as the effects of slaughter weight on carcass and meat quality of BQ were characterized. Results: QingYu pigs exhibited superior reproductive traits. The TNB available to QingYu pigs was more than 8 per parity. The observed repeatability of the reproductive traits of the QingYu pigs was between 0.10 and 0.23. The significantly correlated genetic and phenotypic of reproduction traits were consistent. Interestingly, the BQ pigs exhibited improved carcass quality, with a significant increase in loin muscle area, lean percentage and reduction in sebum percentage. As a result, BQ had higher L45min, lower cooking scores, and lower drip loss. In addition, the loin muscle area, body length, and sebum percentage were significantly higher in 90 and 100 kg animals. Cooking loss showed a significant increase at 80 kg, and marbling increased significantly from 90 kg. Conclusion: The results of this study suggest that QingYu pigs exhibit excellent reproductive properties and heritability of these traits. Crossing with Berkshire is an efficient strategy to improve the carcass and meat quality of QingYu pigs for commercial operations. Furthermore, it appears as though the optimal slaughter weight of BQ pigs is at approximately 90 kg.

$H_{\infty}$ filter for flexure deformation and lever arm effect compensation in M/S INS integration

Liu, Xixiang,Xu, Xiaosu,Wang, Lihui,Li, Yinyin,Liu, Yiting The Society of Naval Architects of Korea 2014 International Journal of Naval Architecture and Oc Vol.6 No.3

On ship, especially on large ship, the flexure deformation between Master (M)/Slave (S) Inertial Navigation System (INS) is a key factor which determines the accuracy of the integrated system of M/S INS. In engineering this flexure deformation will be increased with the added ship size. In the M/S INS integrated system, the attitude error between MINS and SINS cannot really reflect the misalignment angle change of SINS due to the flexure deformation. At the same time, the flexure deformation will bring the change of the lever arm size, which further induces the uncertainty of lever arm velocity, resulting in the velocity matching error. To solve this problem, a $H_{\infty}$ algorithm is proposed, in which the attitude and velocity matching error caused by deformation is considered as measurement noise with limited energy, and measurement noise will be restrained by the robustness of $H_{\infty}$ filter. Based on the classical "attitude plus velocity" matching method, the progress of M/S INS information fusion is simulated and compared by using three kinds of schemes, which are known and unknown flexure deformation with standard Kalman filter, and unknown flexure deformation with $H_{\infty}$ filter, respectively. Simulation results indicate that $H_{\infty}$ filter can effectively improve the accuracy of information fusion when flexure deformation is unknown but non-ignorable.
