다큐멘터리에서의 타자성과 스키마에 관한 연구

원커징(Kejing Wen),최원호(Wonho Choi) 동국대학교 영상문화콘텐츠연구원 2019 영상문화콘텐츠연구 Vol.16 No.-

스키마는 언론과 광고전략 등의 분야에서 응용되고 있다. 한편 다큐멘터리에 관한 연구가 활발히 진행되고 있음에도 불구하고 스키마 이론을 통한 다큐멘터리의 분석에 대한 연구는 부족한 상황이다. 이에 본 연구에서는 다큐멘터리를 타자와 스키마의 관점에서 접근하고자 한다. 연구자는 한국의 KBS가 제작하여 한국과 중국에서 주목을 받은 다큐멘터리 <슈퍼차이나>에서 스키마가 어떻게 적용되고 있는가를 분석하고자 하였다. 구체적으로 "타자"의 스키마가 어떻게 구현하고 있는가를 살펴보고자 하는 것이다. 연구의 결과는 다음과 같다. 첫째, 다큐멘터리에 나타난 파편화된 기호의 조합은 타자와 관련된 객관적인 현실의 구현이며, 타자에 대한 상상이기도 하였다. 둘째, 기호의 배치는 타자와의 관계에 대한 초조와 기대를 드러내고 있었다. 셋째, 서로 다른 문화적 배경으로 인한 스키마의 차이가 "타자"에 대한 이해와 표현의 차이로 이어져 이질적 문화에 대한 재현을 구축하고 있었다. 즉 다큐멘터리의 구축이 "타자"의 스키마를 기반으로 구현된 것임을 알 수 있다. The concept of schema is being applied in the fields of mass media and advertising strategy. While research on documentaries is actively ongoing, analytical research on documentaries using schema theory is lacking as a matter of fact. Therefore, this study sought to approach documentaries from the perspective of others and schema. It aimed to prove how it they were applied at KBS documentary Super China, which attracted public attention in Korea and China. In other words, it examined how schema of "others" was specifically materialized at documentary Super China. The findings were as follow. First, combination of fragmented signs was the materialization of objective reality related with others as well as the imagination on others. Second, layout of signs had both anxiety and expectation for relations with others. Third, the difference of schemas rising from different cultural backgrounds was connected to the difference of understanding and expression of "others", and as a result entity of different cultures affected the formation of schema by "others". That is, formation of documentaries was materialized based on schema of "others".

A Study on The Fantasy in Digital Cinema

WEN KEJING,최원호 한국영상제작기술학회 2020 영상기술연구 Vol.- No.32

With the advent of the movie, the theme of fantasy has been persistently presented. Roger Caillois classify fantasy on fantasy of bias and fantasy of institution. base on this fact, he presents a perspective which states that while that the fantasy embraces ordinary things, he also generates issues with the ordinary and they interfere with each other. By retaining the characteristics of the same, the movie can create scenes of fantasies that reflect the other. In fact, as the expectation of fantasy movie increased, the movie shifts from analog to digital, the possibility of creating fantasy is also diversified. Digitally processed computer graphics images gave new possibility to the movie while fantasy expanding. Cowie Elizabeth emphasized that the subject is not defined since fantasy scenes provide various positions. Therefore, this study unfolds the fantasy of movie realized by digital technology based on the three fantastics of the movie proposed by Cowie Elizabeth. The work for analysis is Disney’s <Beauty and the Beast>, produced in 2017. This is a digital movie composed of virtual characters and Live action characters. Going beyond traditional fairy tale and the animation of 1991, The work of 2017 revealed a new level. The researcher analyzed the <beauty and the beast(2017)> in-depth and the fantasy of bias digital that cannot be realized by analog. The conclusion is as follows. First, in terms of the narrative, the digital has realized the possibility of fantastique by contributing realism on imaginary scenes at the literary level. Second, in the equivalence between characters, the digital lets characters that cannot exist in a real world to be accepted as actual characters by giving realistic realism to the characters. Lastly, the visual substitution achieves fantastique unifying characters by transforming a scene of imagination into a fantastic space. Thus, the digital has been remarkably expanding the fantastic nature of cinema toward the fantasy of bias from the fantasy of institution, and this invites spectators into the space of fantastique. However, Cowie’s characteristics are not the absolute factors to determine the fantastic nature of cinema. Since fantastique can be created through various factors like unconsciousness of spectators, identification, and context in image interpretation. the research aim to discover further characteristics of digital and fantastique in the cinema, from various perspective other than Cowie’s theory.

Insurability of Drunk Driving Liability in China - From the Perspective of Public Function of Liability Insurance -

Li Kejing,Luo Can 중국지역학회 2021 중국지역연구 Vol.8 No.1

음주운전 책임의 보험적용 가능성, 즉 보험사가 피보험자의 음주운전으로 인한 교통 사고에 대해 보험금을 지급해야 하는지에 대하여 중국 내에서 논란이 있어 왔다. 이는 현재 발효 중인 입법과 상충되는데, 1995년 제정된 ‘보험법(保险法)’은 2002년, 2005년, 2013년 개정되면서 이에 대해 부정적인 시각을 견지해 왔다. 또 2006년 ‘자동차교통사 고 강제보험 조례(机动车交通事故责任强制保险条例)’ 제22조는 이 문제에 대하여 별도 의 규정을 두고 있지만, 이견이 있다는 지적에도 2019년 개정이 이루어지지 않았다. 2012년 최고인민법원은 ‘도로교통사고 손해배상 사건의 적용에 관한 법률의 일부 문제 에 관한 최고인민법원의 해석(最高人民法院关于审理道路交通事故损害赔偿案件适用法 律若干问题的解释)’을 공포하고, 제18조에서 이를 지지한다는 입장을 확정하였다. 이처 럼 규정들의 충돌은 법관의 사법 실무에 난제로 작용하고 있다. 한편, 10여 년 전부터 법관이 음주운전 책임의 보험적용 가능성을 지지하는 판례가 나오기도 하였는데, 2006-2012년 168건, 2013-2019년 262건으로 확인되었다. 또 같은 조문을 적용할 때 판사 가 내리는 결론이 일관되지 않은 것으로 나타났다. 책임보험의 공적 기능이라는 관점에 서 볼 때, 음주운전 책임의 보장성이 뒷받침되어야 한다는 점도 법관들이 갈수록 지지 하는 요인이다. 책임보험의 공적 기능은 다른 보험에 비해 피보험자와 피해자를 더 많 이 보호함으로써 국가 금융 리스크 관리의 방안이 된다. 이는 미국의 실무와 이론에서 책임보험의 급속한 발전을 비롯하여 음주운전 책임 문제를 해결하는 근본적인 동력이 라는 것을 증명하고 있으며, 그 진행 과정에서 도덕적 문제를 배제할 수 없다. 중국의 이와 같은 논란과 관련하여 균형 잡힌 책임보험의 공적 기능과 상업적 관계를 발전시키 는 데는 최근 영국의 자동차보험제도 개혁의 성과를 참고하여 중국 입법을 보완하여야 할 필요가 있을 것이다. 이에 본 연구에서는 먼저 자동차 음주운전의 보험금 지급과 관련하여 중국 입법에서의 충돌 여부를 확인하고, 실제 사례에서 판사의 지지 관점을 분석한다. 이를 다시 책임보험의 공공기능 관점에서 음주운전의 위험성을 입증한다. 이를 통해 책임보험의 공공기능과 상업성을 어떻게 균형 있게 할 것인지에 대하여 의견 을 제시하였다. The insurability of drunken driving liability, that is, whether insurance companies should pay for traffic accidents caused by the insured who is a drunk driver, has always been a controversial issue in China. Current legislation is conflicting. Insurance Law of the People’s Republic of China 1995 insists a negative view through the amendments in 2002, 2005, and 2013. Article 22 of Regulation on Compulsory Traffic Accident Liability Insurance for Motor Vehicles 2006 specifically this issue is believed to be ambiguous and still did not respond it in the 2019 revision. the Supreme people's Court in 2012 enacted the Interpretation on Several Issues Concerning the Application of Law in the Trial of Cases on Compensation for Damage in Road Traffic Accidents, which has established a supportive position in Article 18. These conflicts have been bringing difficulties to Judges in judicial practice. On the other hand, Judges have been increasingly inclined to support the insurability of drunk driving liability in judicial cases since more than a decade ago, as confirmed by the results of 168 cases between 2006 and 2012 and 262 sample cases between 2013 and 2019. However, these cases also show that the conclusions reached by judges in the application of the same provision are not uniform. From the perspective of the public function of liability insurance, the insurability of drunk driving liability should be supported, which is also the main reason why more and more Judges have been becoming supporters. Compared with others, the public function of liability insurance means that it can provide more protection both for the insured and victims, as a result, it would be a financial approach in governing risks of the State. And the practice and theoretical research in the US have proved that it is the fundamental driving force for the rapid development of liability insurance, including settling the problem of drunk driving, and the decline of moral hazard is also essential for the developing process. As far as the dispute, we should balance the relationship between public function and the commercial nature of liability insurance in the development, improve Chinese law by learning from the reform achievements of the UK in recent years. Accordingly, this article is divided into four parts. First of all, conflicts in current Chinese legislation are sorted out; secondly, there comes an analysis of the supporting views by Judges in judicial cases; thirdly, a key argument is demonstrated, that is, the insurability of drunk driving risk should be affirmed from the perspective of the public function of liability insurance; finally, the focus is how to balance the public function and commercial nature of liability insurance.

In Situ Synthesis of Carbon Nanotubes/Graphene Nanoplateles Hybrid Materials with Excellent Mechanical Performance

Menglei Wang,Kejing Yu,Kun Qian 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.4

A two-step method for the preparation of hybrid materials consisting of multi-walled carbon nanotubes (MWCNTs) attached to graphene nanoplatelets (GNPs) was proposed. Firstly, poly (acryloyl chloride) was grafted in situ onto the surface of MWCNTs. Secondly, the obtained MWCNTs (MWCNTs-PACl) were reacted with acid-treated GNPs to form a nanotube–polymer– graphene hybrid. Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, transmission electron microscopy (TEM) and thermal gravimetric analysis (TGA) were used to investigate the forming of the hybrid materials. FTIR results showed that MWCNTs/PACl and GNPs were successfully bridged by chemical bonds like O–C=O and C–O–C. Raman spectroscopy furthermore revealed that acryloyl chloride can be used to connect the MWCNTs and GNPs due to the defects of MWCNTs, and consequently the defects of the hybrid materials were limited. Meanwhile, TEM observation demonstrated the nanostructure clearly in which the MWCNTs with a polymer layer were attached successfully on the surface of GNPs. And TGA curves reflected that the content of MWCNTs and GNPs was about 46.5% in the hybrid materials. In addition, the tensile tests results showed that MWCNTs/GNPs hybrid materials can improve the mechanical performance of epoxy composites in higher degree, compared with MWCNTs or GNPs particles alone.

중국 리얼리티 프로그램의 발전에 관한 연구 -한국의 <런닝맨>과 중국의 <달려라 형제>를 중심으로-

WU LI ZHONG,WEN KEJING,최원호 한국영상제작기술학회 2020 영상기술연구 Vol.- No.32

In recent years, with the development of Chinese variety shows, a variety of reality shows came into being, among which, <The Voice of China> and <Dad, Where Are We Going> of Zhejiang Satellite TV are well received by the audience. The success of those programs lies in the introduction of overseas programs’ copyrights. Besides, in 2014, Zhejiang Satellite TV broadcasted an outdoor reality show <Running Man>, which has been popular so far. In this thesis, a comparison between Chinese <Running Man> and its copyright prototype <Running Man> in South Korea is carried out to explore reasons for its success. By analyzing Chinese <Running Man> and South Korean <Running Man>, the development, introduction, learning and innovation of Chinese reality shows are expounded. And through a comparative study of the original version and the Chinese version, successful directions for reality shows are dissected, and localization strategies and improvement plans for reality shows that introduce overseas copyright are proposed. 최근 몇 년간 중국 리얼리티 프로그램이 빠르게 발전하면서 다양한 리얼리티 프로그램이 등장했다. 그중 시청자들에게 많은 사랑을 받은 프로그램은 저장위성 TV의 <The Voice of China>와 후난 TV의 <아빠 어디가>이다. 이 프로그램들이 성공한 것은 해외 프로그램의 포맷을 도입했기 때문이다. 그리고 2014년에는 저장 위성TV가 리얼 버라이어티 프로그램인 <달려라 형제>를 방영하면서 현재까지 꾸 준한 인기를 끌고 있다. 이에 본 연구에서는 중국의 <달려라 형제>와 포맷의 원형 인 <런닝맨>을 비교, 연구하여 그 성공 원인을 탐구하고자 하였다. 이를 위해 리얼리티 쇼의 발전, 도입, 학습, 혁신의 과정을 고찰한 후, <달려라 형제>와 <런닝맨> 을 사례중심으로 연구하였다. 그리고 오리지널 버전과 중국 버전의 비교함으로써 리얼리티 쇼 프로그램의 성공 방향을 분석하고, 그럼으로써 포맷을 도입한 리얼리 티 쇼 프로그램의 현지화 전략과 개선안을 도출, 제시하고자 하였다.

Circuit and Control Scheme of Converter-Based Emulation for Control Testing of AC Microgrid

Jiashi Wang,Ke Ma,Tingting Liu,Siyu Cao,Kejing Liang,Shaolun Xu,Xu Cai 전력전자학회 2023 ICPE(ISPE)논문집 Vol.2023 No.-

Due to the fast development of renewable energies, the microgrid has been proposed as a novel configuration of modern power grids integrated with a large number of grid-connected converters. To achieve flexible functions in microgrids, various control schemes are implemented in the grid-connected converters and play a vital role in the operation of the microgrid. In this case, the emulation of the microgrid is becoming an emerging need for the testing of AC microgrid controls. However, the conventional emulation approaches are cost and bulk in the emulation of microgrids with complex configurations. In this paper, a novel emulation system is proposed for the test of various AC microgrid control schemes. a low-cost circuit configuration, which includes two face-to-face-connected DC-AC converters and some passive loads, is introduced with the possibility to recreate most of the fundamental control schemes in a typical AC microgrid. Besides, different types of control schemes are implemented in the two converters to flexibly recreate the corresponding control behaviors.
