본 논문에서는 다항식형태의 비선형성을 갖는 미지의 파라미터를 갖는 2차원의 공탄성(aeroelastic) 시스템에 대한 제어기 설계를 다룬다. 특히 제어기구현에 사용되는 상태 및 actuator 구동기신호가 크기, 변화율 및 대역제약조건을 가지는 경우는 실현이 불가능한데, 이 경우에도 각각에 대한 필터를 사용하여 해결한다. 우선 backstepping에 기초한 오차신호를 정의하고, 명령신호 및 필터출력 신호에 대한 추적오차신호를 정의하며, 필터구성에 따른 보상된 추적오차신호를 재정의한다. 안정화를 위하여 Lyapunov함수를 도입하고, 안정성 원리에 따라 적응식을 유도한다. 시뮬레이션을 통해서 유용성을 입증한다. This paper deals with a controller design for a 2 dimensional aeroelatic model which has unknown parameters including polynomial type nonlinearity. Actually in case of state and acuator signal having magnitude, rate and bandwidth limitations, the controller can't be implemented and so in each case, a filter is used for implementation. First, error signals are defined upon the backstepping theory, and tracking error signals are also defined due to command signal and filter signals and then compensated tracking error signals are defined. Lastly, a Lyapunov function is defined for the stabilization and from this method, an adaptive law is derived. Simulations are done for the demonstrtion of the effectiveness of the algorithms.

This study investigates the microstructural properties of CoCrFeMnNi high entropy alloy (HEA) oxynitride thin film. The HEA oxynitride thin film is grown by the magnetron sputtering method using nitrogen and oxygen gases. The grown CoCrFeMnNi HEA film shows a microstructure with nanocrystalline regions of 5~20 nm in the amorphous region, which is confirmed by high-resolution transmission electron microscopy (HR-TEM). From the TEM electron diffraction pattern analysis crystal structure is determined to be a face centered cubic (FCC) structure with a lattice constant of 0.491 nm, which is larger than that of CoCrFeMnNi HEA. The HEA oxynitride film shows a single phase in which constituting elements are distributed homogeneously as confirmed by element mapping using a Cs-corrected scanning TEM (STEM). Mechanical properties of the CoCrFeMnNi HEA oxynitride thin film are addressed by a nano indentation method, and a hardness of 8.13 GPa and a Young's modulus of 157.3 GPa are obtained. The observed high hardness value is thought to be the result of hardening due to the nanocrystalline microstructure.

영화 연기와 연출을 위한 훈련 프로그램 방법

이정국(Jeong-Gook Lee) 한국콘텐츠학회 2010 한국콘텐츠학회논문지 Vol.10 No.9

본 논문의 목적은 영화연기와 연출을 위한 훈련 프로그램의 필요성과 그 대안적인 방식을 소개하는 것이다. 우리 한국에서 영화나 방송의 최근 연기경향은 생활연기가 주를 이루고 있다. 그러나 연기교육은 여전히 연극 전문가들에 의해 이루어지고 있고, 그로인해 연극 훈련프로그램에 의해 연기를 교육한다. 또한 영화감독들의 연기연출에 대한 교육도 거의 없다. 그래서 영화연기와 연기 연출을 할 수 있는 훈련 프로그램이 필요하다. 이 글은 필자가 실제로 영화연기 훈련 프로그램 개발을 위해 실시한 단편영화 워크숍 〈생활연기의 힘〉과 〈연기연습〉제작과정을 다루고 있다. 이 훈련 프로그램은 이미 스타니슬라브스키가 연극 연습을 위해 활용한 에쮸드를 일부 응용하고, 리 스트라스버그의 액터스 스튜디오에서 체계화된 영화연기 훈련법인 매소드 연기법을 참조하고 있다. 무엇보다도 이 프로그램의 핵심은 기존 연기훈련법에 카메라 활용이 들어간다는 것이고, 배우뿐 아니라 영화 감독과 스탭들이 같이 참여해서 완성한다는 것이다. 이 글에서는 실제로 두 단편 워크숍을 통해 그러한 훈련법의 실험이 객관적인 성과를 이루었음을 입증하고 있다. 본 훈련 프로그램의 교육은 아마추어와 준 프로, 그리고 프로 연기자에 따라 달리 적용해야한다. The purpose of this thesis is to introduce the alternative method of the new training program for film acting and directing. Recently in Korea, acting in movies has become a trend and broadcasting still depicts reality. But men of the theater is usually privileged getting the most acting education offered by the theater training program. They also is hardly teach about acting's directing for film directors. So I thought of establishing a new training program for film acting and acting's directing. I made two short films 〈the power of living acting〉, 〈acting rehearsal〉 that I had practical training program for film acting as practical text. This program applied partially 'Atude' that Stanislavsky devised for theater acting practice, and referred to 'Method Acting System' that Lee Strasberg made for film acting at the Actors Studio. Another main point of this program is camera use. That training program can be attended not only by actors but also by director and film staff. Through this thesis, I wish to prove my new training program for film acting and acting directing. The focus of this training is to target a better execution according to the group you belong to whether amateur group, associate professionals, professional actors.

〈케이프 피어〉의 리메이크 영화 비교 연구

1. Meaning and type of Remake 'Remake' is a new version of an old film, and to make film again or in a new way. Actually 'remake' in the scripts almost is the same meaning with adaptation. The origina1(work) only is not literature or drama but a film itself. 2. Comparative directing study of J. Lee Thompson and Martin Scorsese I selected Cape Fear as a main text because each two film stand for well-made Hollywood movies and the style of Auteurism director 1) Script- adaptation I think that the most part of film directing is script. To select and adapt a good original work also the very important process in directing. ① Concrete genre- horror thriller ② Main theme- study of human nature ③ Vivid character-Sam, Dani, Rori ④ Reinforcement of episodes ⑤ Addition of motif ⑥ Variation of last scene 2) Aesthetics of film directing ① Cinematography- camera's composition and movement ② Comparative of each two scene ③ Mise-en-scene ④ Editing- psychological description 3) Acting Film directing is composed of harmony of script, acting, directing. All actors of Scorsese's Cape Fear is played excellent acting 3. Epilogue The most recent, 'remake' is a trend. Some people could regard it as negative tredency. but I think those trend would be another alternative because lack new material and idea.

단편영화의 미학과 창작 원리

이정국(Lee Jeong Gook) 한국영화학회 2011 영화연구 Vol.0 No.47

This thesis is composed of form, esthetics, and writing principle of short film. In general, the Short film means that the running time is from 10 minutes to 40 minutes. Short film is one of the most important work shop in college film education. So we need various debates about it. Form of short film is classified of three types: classical story, dramatic reversal, to stress image. And the criteria of the esthetics about a short film is also composed of three elements: cinematic perfection, originality, powerful theme. I think, the writing principle of the good short film can be classified of 7 elements: 1) the very simple theme and subject matter and selection of fitting composition. 2) esthetics of simplicity. 3) effective use of irony, motif, reversal. 4) creative view and original expression. 5) narrative powers of persuasion and theme. 6) refined techniques and perfection of acting directing. 7) emotional bond of sympathy. As a results of analysis, A good short film is the works that harmonizes with cinematic perfection and originality, and powerful theme well. Of course, even if one of those three elements outstand, the short one can be a good work.

This study examined the analysis of the relationship between leisure identity, leisure activities specialization and serious leisure of mountain climbing club members. The number of the surveyed for this study was 279 who participated in the mountain climbing club members. The reliability and validity test of the questionnaire itself was conducted by using SPSS & AMOS Window 19.0 program; the result of descriptive analysis, factor analysis, correlation analysis, standard multiple regression analysis, path analysis are as follows; The results were as being follows. First, the leisure identity is partially influences on the leisure activities specialization and serious leisure of mountain climbing club members. Second, leisure activities specialization in mountain climbing club members is partially influences on the serious leisure of mountain climbing club members. Lastly there is a causal relationship between the recreation specialization, leisure activities specialization and serious leisure of mountain climbing club members.

영화에서 코미디의 작동 원리 연구

이정국 ( Jeong Gook Lee ) 한국영화교육학회 2011 영화교육연구 Vol.13 No.-

Comedy is the most popular genre since the early film history. Comedy also is the important genre in Korea movie, and was often used in other genre. So through this thesis, I tried to analyze about origin of the word ``comedy``, and what principle the comedy operate. First of all, I tried to arrange terms of slapstick, humor, gag etc. The key point of this thesis is that extract operating principle of the comedy. The major basic text is ``Le rire. Essai sur la signification du comique`` by Henri Bergson. The operating principle of comedy I studied through this thesis classified by 14 elements as follows; attitude of basic human, mechanical action, exaggeration, misunderstanding, imbalance, mistake, inversion, reversal, acting, ignorance, irony etc. Of course, To operate comedy can be added various another categories except to 14 elements mentioned above, for example, there are some ones like acting of player, fitting timing, audience target etc. In conclusion, I mentioned the relativity between tragedy and comedy like Woody Allen and Charlie Chaplin`s films.
