시각적 연출에 의한 3D 입체 애니메이션 표현 연구

김정현    (Kim, Jung-Hyun) 한국만화애니메이션학회 2012 만화애니메이션연구 Vol.- No.26

애니메이션의 목적은 움직임을 통해 재미있는 스토리를 관객에게 전달하는 것이라고 할 수 있다. 이러한 목적을 달성하기 위해 애니메이션은 탄생 이후 지금까지 100여년 이상의 시간동안 수많은 기술들을 도입하면서 다양한 내러티브 방법과 시각 표현 방법을 개발해 왔다. 또한 표현 기술력이 발달하면서 애니메이션을 구성하는 모든 요소들도 점점 체계화되어 왔고, 동시에 현실 그 이상의 세계를 표현할 수 있도록 해 주었다. 말 그대로 애니메이션을 제작하는 감독이 상상하는 모든 것들을 스크린을 통해 관객이 눈으로 볼 수 있는 시대가 된 것이다. 그리고 현재에는 애니메이션을 관람하는 관객이 마냥 프레임 안에서 움직이는 그림에 의해 즐거움을 느끼게 되는 시대를 넘어서도록 많은 노력이 이루어지고 있다. 즉, 수동적으로 바라보는 애니메이션을 넘어 관객이 직접 느끼며, 체감하는 애니메이션으로 목적성이 변화하고 있다는 것이다. 이런 과정에서 그 중심에 3D 입체라는 기술이 애니메이션의 새로운 즐거움을 표현할 수 있도록 해주고 있다. 얼마 전, 국내에서도 극장용 3D 입체 애니메이션이 제작되었으나, 해외의 3D 입체 애니메이션과 같은 완성도 높은 영상미를 기대했던 관객에게새로운 즐거움을 주지 못해 흥행 면에서 이렇다 할 성적을 거두지 못하였다. 이것은 국내의 입체 애니메이션 제작 산업이 아직 초보적인 단계에 불과하여 3D 입체 애니메이션 제작에 대한 인력 및 기술, 경험이 절대적으로 부족한 상태에서 제작되었기 때문이다. 그리고 대부분의 입체에 대한 연구가 재현 기술적 문제에 집중되어 있어 관객들이 직접적으로 접하게 되는 영상 그 자체에 대한 연구 또한 부족하거나 미흡한 실정인 것도 커다란 문제라 할 수 있다. 이러한 국내 상황 속에서 2010년에 개봉되었고, 현재까지 최고의 3D 입체 애니메이션 흥행작으로 손꼽히고 있는 드림웍스 작품인 <드래곤 길들이기>의 입체영상 화면은 연구될 가치가 충분하다 할 수 있다. 따라서 본 논문은 양질의 국내 3D 입체 애니메이션 제작 및 전문 인력 양성 시 기초자료로 활용되고자 풍부한 입체감을 전달하기 위해 화면을 담아내는 시각적 연출을 중심으로 이론적 고찰과 사례를 분석하여 연구하였다. 그 결과 3D 입체 애니메이션은 새로운 분야가 아닌 기존 영상미학의 원리를 기반으로 입체영상의 특성이 적용되어져 확장되고 변화된 영역인 것을 알 수 있었다. 이러한 연구를 통해 실재감 재현을 위한 3D 입체 애니메이션 콘텐츠 제작에 필요한 이론적 기초연구의 토대를 구축하는데 도움이 될 것으로 본다. The purpose of animation is to give interesting stories to an audience through motion. To achieve the purpose, over the past century since its inception, animation has adopted many kinds of technologies, and thus developed diverse narrative methods and visual expression techniques. In addition, with the advancement of expression techniques, all elements making up animation have gradually been systemized, and at the same time, have helped express the worlds beyond the reality. As a result, people have faced the era when an audience can watch everything imaginated by an animation director on a big screen. These days, more efforts have been made in order for the audience to feel much more than enjoy pictures moving in a frame. In other words, the purpose of the animation is changing from the passive viewing of animation to feeling and sensing stuffs through the animation. In the center of the changing process is 3D technology which gives new interesting to an audience. Sometime ago, a 3D animation movie was produced in Korea. But it did not bring out box-office profits, for it failed to give satisfaction to an audience who expected high perfection and beauty being able to be rivalled to those of international 3D animation movies. The failure is attributable to the fact that the domestic 3D animation production industry is merely in the early stage, and has not sufficient human resources, technology, and experiences in producing 3D animation films. Moreover, the problem is that most studies on 3D focus on the technologies related to reenactment, but that few studies on the images, which an audience directly faces, have been conducted. Under the domestic circumstance, the study on stereoscopic image screen of <How to Train Your Dragon>, a 3D stereoscopic animation film which was released in 2010 and has been seen as the best successful 3D stereoscopic animation, is worthwhile. Thus this thesis conducted theoretical consideration and case analysis focusing on the visual direction that creates the pictures to deliver abundant three dimensional effect so that it can be used as a basic data when producing high quality-domestic 3D animation and training professional labor forces. In the result, it was found that the 3D animation was not a new area, but the area which has been expanded and changed by applying the characteristics of 3D image based on the principles of the existing media aesthetics. This study might be helpful to establish the foundation of the theoretical studies necessary for producing 3D animation contents for realizing the sense of reality.

김정현,강경원,유병찬,최선미,백혜기,임승민,안정조,설인찬,김윤식,Kim, Jung-Hyun,Kang, Kyung-Won,Yu, Byeong-Chan,Choi, Sun-Mi,Baek, Hye-Ki,Lim, Seung-Min,An, Jung-Jo,Seol, In-Chan,Kim, Yoon-Sik 대한한방내과학회 2007 大韓韓方內科學會誌 Vol.28 No.4

Background and purpose : Stroke is one of the most deadly diseases and a leading cause of disability. Lipids confer an increased risk for cardiovascular morbidity and mortality. In spite of many studies on the relationship between stroke and lipids, their relationship is not clear. This study was undertaken to determine whether lipids were associated with stroke. Method : We compared the components of blood lipids between stroke patients group (n=217,Cases), non-stroke control group (n=160, Controls) and healthy control group without hypertension, diabetes mellitus, ischemic heart disease, or hyperlipidemia (n=140, Normals). These data were statically analyzed by general linear models and binary logistic regression analysis to get each adjusted odds ratio. Result : The results were as follows. The blood levels of total cholesterol (T-Chol), triglyceride (TG) and low density lipoprotein cholesterol (LDL-Chol) were significantly higher in patients of ischemic stroke, while the blood levels of T-Chol and LDL-Chol were significantly lower, and the blood levels of TG significantly higher in patients of hemorrhagic stroke. The blood level of high density lipoprotein cholesterol (HDL-Chol) was significantly lower in all cases. Conclusion : These results suggest that high TG and low HDL-Chol may be risk factors of hemorrhagic stroke and ischemic stroke, high T-Chol and LDL-Chol may be risk factors of ischemic stroke, and low T-Chol and LDL-Chol may be risk factors of hemorrhagic stroke in Koreans.

Objectives : The aim of this study was to investigate the effect of Trichosanthis Semen Herbal-acupuncture(TS-HA) at Joksamni(ST36) on ovalbumin-induced asthma in mice. Methods : C57BL/6 mice were sensitized and challenged with ovalbumin(OVA) once a week for twelve weeks. The experimental group was treated with 1% concentrations of TS-HA at Joksamni(ST36) three times a week for the last eight weeks. Results : 1. The weight and total lung cells of the mice in the group treated with TS-HA decreased significantly compared with those of control group. 2. Total leukocytes and eosinophils in Bronchoalveoler-lavage fluid(BALF) of the mice in the group treated with TS-HA decreased significantly compared with those of control group. 3. Eosinophils in BALF of the mice in the group treated with TS-HA in photomicrographs decreased significantly compared with those of control group. 4. According to histological analysis of lung sections, adhension of collagen in TS-HA decreased significantly compared with that of control group. 5. The concentration of IgE, IL-4, IL-5 in BALF and IL-4, IL-5, IL-13 in serum of the mice in the group treated with TS-HA decreased significantly compared with that of control group. 6. The number of $Gr-^+/CD11b^+,\;CD11b^+,\;CD3e^-/CCR3^+,\;CD4^+,\;CD8^+\;CD3e^+/CD69^+,\;CD23^+/B220^+\;cells$ in the lungs of the mice in the group treated with TS-HA decreased significantly compared with those of control group. Conclusion : These results suggest that Trichosanthis Semen-herbal acupuncture at Joksamni(ST36) done on C57BL/6 mice is effective in part in relieving OVA-induced asthma in C57BL/6 mice.

김정현,조현경,유호룡,설인찬,김윤식,Kim, Jung-Hyun,Jo, Hyun-Kyung,Yoo, Ho-Rhyong,Seol, In-Chan,Kim, Yoon-Sik 대한한방내과학회 2006 大韓韓方內科學會誌 Vol.27 No.1

Objectives : This experiment was performed to determine the effects of the Jeseubsungi-tang(JSSGT) on hyperlipidemia-induced by hypercholesterolemic diet in mice. Methods : C57BL/6 mice were sensitized with a hypercholesterolemic diet for 6 weeks. Experimental group was treated with $150mg/d{\ell}$ concentrations of JSSGT for 4 weeks (once a day). Results: JSSGT-treated mice showed a body weight decrease compared to normal group. JSSGT-treated mice showed a significant decrease in cholesterol, total cholesterol, triglyceride, ALT and LDL-cholesterol levels compared to hyperlipidemia-induced control group. However, HDL-cholesterol levels in JSSGT-treated group significantly increased compared to the hyperlipidemia-induced control group. Conclusion : These results suggest that JSSGT is effective in treating hyperlipidemia. Because only hyperlipidemic mice were studied, further research is needed.

김정현,우성충,최낙삼,Kim, Jung-Hyun,Woo, Sung-Choong,Choi, Nak-Sam 한국비파괴검사학회 2003 한국비파괴검사학회지 Vol.23 No.5

본 연구에서는 연속형 일방향 및 수자직 유리섬유강화 복합재료로 인장 시험편을 만들어 AE 특성에 대한 섬유배향 효과를 살펴보았다. AE 신호들을 STFT 처리하여 특성별로 분류하였으며, 반사식 및 투과식 편광현미경을 이용하여 시험편의 손상영역을 관찰하였다. 저주파수 대역의 약한 AE 신호들은 모재 및 계면에서의 손상으로 나타났으며, 높은 진폭의 고주파수 대역 AE 신호들은 섬유 파단에 기인하였다. 섬유 파단 과정에서 발생하는 고진폭의 AE 사상률을 기본 특성 데이터로 하여 다른 섬유배향과 노치방향을 가진 복합재에서의 파괴과정을 특징지을 수 있었다. 결론적으로, AE범은 연속형 유리섬유 강화 복합재의 파괴거동을 탐지하는데 있어 유용함을 알 수 있었다. The effects of fiber orientation on acoustic emission(AE) characteristics have been studied for the unidirectional and satin-weave, continuous glass-fiber reinforced plastic(UD-GFRP and SW-GFRP) tensile specimens. Reflection and transmission optical microscopy was used for investigation of the damage zone of specimens. AE signals were classified as different types by using short time fourier transform(STFT) : AE signals with high intensity and high frequency band were due to fiber fracture, while weak AE signals with low frequency band were due to matrix and interfacial cracking. The feature in the rate of hit-events having high amplitudes showed a process of fiber breakages, which expressed the characteristic fracture processes of individual fiber-reinforced plastics with different fiber orientations and with different notching directions. As a consequence, the fracture behavior of the continuous GFRP could be monitored as nondestructive evaluation(NDE) through the AE technique.

쉴드터널의 사다리꼴 세그먼트라이닝 배열방법 개선에 대한 연구

김정현,강경진,Kim, Jung-Hyun,Kang, Kyung-Jin 한국터널지하공간학회 2007 한국터널지하공간학회논문집 Vol.9 No.1

본 연구는 쉴드터널 공사시 사용되는 사다리꼴 세그먼트라이닝의 배열방법에 관한 것이다. 사다리꼴 세그먼트라이닝은 공장에서 기제작된 Taper를 가진 콘크리트 세그먼트를 터널내에 반입과 동시에 조립하므로써 형성되는데, 이렇게 형성된 사다리꼴 세그먼트라이닝은 회전조립시 Taper량의 계산에 의하여 단 한가지 타입으로 다양한 터널노선에 맞는 배열을 가능하게 하므로 세그먼트에 의한 터널시공시 가장 효율적인 공법이라 할 수 있다. 본 연구는 사다리꼴 세그먼트라이닝의 설계제원 및 터널 노선의 선형(직선 혹은 곡선)의 조건을 분석하여 터널선형에 맞는 배열방법을 고안하고 실제 터널내에서 작업자가 활용할 수 있는 컴퓨터 프로그램을 제작하여 자동으로 배열순서를 결정하는 원리에 대하여 설명하고자 한다.또한,가변하는 실제 터널내에서 작업자가 세그먼트라이닝의 배치상태를 측정한 값이 컴퓨터 프로그램에서 계산된 결과와 상이할 때 작업자는 측정한 데이터를 컴퓨터 프로그램에 입력하여 프로그램의 계산상태를 실제 세그먼트 조립상태로 일치시킨 후, 다음 세그먼트라이닝의 배열자료로 사용하여 연속된 작업이 되도록 하는 방법을 제공하는 것이 본 연구의 기술적 요지이다. This study is about an arrangement method of trapezoidal pre-cast segment lining that can be applied in shield tunnel construction. Trapezoidal segment lining is formed by assembling tapered pre-cast concrete segments taking advantage of the tapered shape of pre-cast segments upon delivery on site. By calculating tapering of the segments manufactured in single type and rotating the segments when putting them together, a variety of tunnel alignments can be arranged in the most efficient way. Once the design criteria and tunnel alignment (straight or curved) is analyzed, the sequence of assembling trapezoidal segments in compliance with tunnel alignment will be computed. On site an operator can utilize the softwareto automatically determine sequential arrangement of trapezoidal segments. When the actual arrangement of segmental lining is different from the computed output, the operator can input the actually measured values to coincide the computerized calculation with the real status of assembly. Then the adjustment will be the basis of subsequent arrangement of segments, thus the continuity of work can be guaranteed.

중·저온형 고체산화물 연료전지 공기극의 적용을 위한 Sr이 치환된 이중층 페로브스카이트 기반 복합공기극 물질의 분말 크기 및 열 사이클에 따른 전기화학특성 분석

김정현,Kim, Jung-Hyun 한국전기화학회 2011 한국전기화학회지 Vol.14 No.3

The electrochemical characteristics from various particle sizes of $Ce_{0.9}Gd_{0.1}O_{2-{\delta}}$ (CGO91) in composite cathode comprised of the samarium-strontium doped layered perovskite ($SmBa_{0.5}Sr_{0.5}Co_2O_{5+{\delta}}$) and CGO91 have been investigated for possible application as a cathode material for an intermediate temperature-operating solid oxide fuel cell (IT-SOFC). The area specific resistances (ASRs) of composite cathodes with CGO91 having smaller particle size ($0.4\sim42{\mu}m$) and SBSCO of 1 : 1 ratio (50wt% SBSCO and 50 wt% CGO91, SBSCO: 50) give the lowest ASR of $0.10{\mu}cm^2$ at $600^{\circ}C$ and $0.013{\Omega}cm^2$ at $700^{\circ}C$. However, composite cathodes with having relatively bigger CGO91 particle size show the two times higher ASR results than those of SBSCO : 50. From the 10 times thermal cycles in SBSCO : 50, the ASRs of SBSCO : 50 increased from $0.0193{\Omega}cm^2$ to $0.094{\Omega}cm^2$ at $700^{\circ}C$, however, the ASR value was maintained after 7 times of thermal cycling. 본 연구에서는 Sr이 치환된 이중층 페로브스카이트($SmBa_{0.5}Sr_{0.5}Co_2O_{5+{\delta}}$, SBSCO)와 전해질 물질로 사용되는 $Ce_{0.9}Gd_{0.1}O_{2-{\delta}}$ (CGO91)을 기반으로 한 중 저온형 고체산화물 연료전지 (ITSOFC) 복합공기극의 분말 크기와 열 사이클에 대한 전기화학특성을 연구하였다. 복합공기극의 모체가 되는 SBSCO에 CGO91물질을 이용하여 면적비저항을 확인 한 결과 약 $0.54\sim9.04{\mu}m$의 분말 크기를 보이는 SBSCO와 $0.4\sim42{\mu}m$의 분말 크기를 보인 CGO91이 각각 50 wt%로 구성된 SBSCO : 50 복합공기극이 600 및 $700^{\circ}C$에서 약 0.102 및 $0.013{\Omega}cm^2$의 우수한 면적비 저항을 가지는 것을 확인 하였으며 상대적으로 분말 크기가 큰 CGO91 분말을 이용한 두 개의 공기극의 경우 $700^{\circ}C$에서 약 $0.260{\Omega}cm^2$와 $0.055{\Omega}cm^2$의 특성을 보여주었다. 10회에 걸친 열 사이클실험을 통하여 SBSCO : 50의 면적비저항은 $0.0193{\Omega}cm^2$에서 $0.094{\Omega}cm^2$로 증가하였으며 7회 이후의 면적비저항은 일정하게 유지됨을 확인하였다.

김정현,장수경,Kim, Jung-Hyun,Chang, Soo-Kyung 대한물리치료학회 2014 대한물리치료학회지 Vol.26 No.5

Purpose: The purpose of this study was to assess the effects of robo-horseback riding with changes of pelvic tilting and speeds on muscle activities of trunk and lower limb in healthy adults. Methods: Thirty healthy adults were recruited for this study. Subjects performed robo-horseback riding at three pelvic postures (anterior tilting pelvic posture: AP, neutral pelvic posture: NP, posterior pelvic posture: PP) and different speeds (moderate and fast speed). Muscle activities were recorded from the trunk muscles (rectus abdominis [RA], T2 paraspinalis [T2 PS], L2 paraspinalis [L2 PS]) and lower limb muscles (rectus femoris [RF], vastus medialis [VM], vastus lateralis [VL], biceps femoris [BF], gastrucnemius [GCM]). Results: Significantly higher RA activities were observed under the PP condition than under the AP and NP conditions at both speeds. Significantly higher L2 PS activities were observed under the AP condition than under the PP and NP conditions at both speeds. Significantly higher T2 PS activities were observed under the AP condition than under the PP and NP conditions at fast speed. However, the muscle activities of the VM and GCM did not show significant changes with changes in pelvic posture at both speeds. All muscle activities were significantly higher under the fast speed than under the moderate speed in three pelvic postures. Conclusion: There were significant differences in the changes of pelvic tilting on muscle activities of trunk and lower limb were observed in healthy adults. NP condition can be introduced the most efficienct posture for muscle activities of trunk and lower limb in robo-horseback riding.

김정현,김은영,정경숙,류미라,Kim, Jung-Hyun,Kim, Eun-Young,Chung, Kyung-Sook,Rhyu, Mee-Ra 한국응용생명화학회 2003 한국농화학회지 Vol.46 No.4

최근 수입자유화 이후 중국산 한약재의 수입이 증가하면서 수입산과 국산의 명확한 판별이 요구되고 있는 가운데 수입이 급증한 품목 중 하나인 천궁을 선택, CE를 이용한 분석조건을 확립하고 원산지판별에의 적용가능성을 검토하였다. 분석을 위한 지표물질의 추출에는 30% ethanol 을 사용하였고, $50\;{\mu}m\;I.D.{\times}27\;cm$ 길이의 uncoated fused-silica capillary를 이용하여 $40^{\circ}C$, 10 kV로 200 nm에서 분석하였다. 0.1 M phosphate buffer(pH 2.5)에 40% methanol과 15 mM IDA를 첨가하여 분석 buffer로 사용하였고, 국산시료는 5초, 수입산은 2초 동안 pressure injection하였다. 분석 시 시료 injection 전에 증류수로 4분간 흘려주고 분석 buffer로 10분간 평형화시켰으며 분석이 끝난 후 0.1M phosphoric acid와 1N sodium hydroxide를 각각 4분씩 흘려 분석의 재현성을 높이고자 하였다. 이상의 조건으로 시중에 유통되는 국내산(62점)과 수입산(51점) 천궁을 분석한 결과 전체 peak에 대한 구성비율이 서로 차이를 나타내는 peak LW-1과 peak LW-5(용출시간 약 11분, 14분)를 원산지 판별에 적용할 수 있는 peak로 도출하였으며, 이 peak를 이용한 국산 및 수입산 천궁의 원산지 판별율은 국산이 약 65%(총 62점 중 40점을 바르게 판별), 수입산은 약 63%(총 51점 중 32점을 바르게 판별)로 나타났다. Optimal extraction, separation and capillary rinsing conditions for capillary electrophoresis (CE) were established to discriminate the geographical origin of ligusticum root (Ligusticum wallichii) using 113 samples (domestic sample n = 62, foreign sample n = 51). Ligusticum root was extracted with 30% ethanol and separated on a uncoated fused-silica $(50\;{\mu}m{\times}27\;cm)$ capillary. Conditions for optimal analysis include: temperature, $40^{\circ}C$; voltage, 10 kV; and pressure injection time, domestic and foreign samples were 5 sec and 2 sec, respectively. The optimal separation buffer was 0.1 M phosphate buffer (pH 2.5) containing 15 mM iminodiacetic acid with 40% methanol. Under the optimal conditions established for CE, the ratio of specific peak area (peak LW-1) to other peak area (peak LW-5) was effective in discrimination geographical origin of ligusticum root. The mean accuracy for correct discrimination of geographical origin of domestic and foreign ligusticum roots were 65% and 63%, respectively.
