  • We retrospectively analyzed the outcomes in patients who underwent reirradiation for brain metastasis. Twenty-three patients with brain metastases who were initially treated with palliative brain radiotherapy and were retreated with a second course of brain RT between June 2008 and December 2012. WBRT, 3DCRT and SRS were used for brain metastasis. The median dose of the first course of WBRT was 30 Gy (range, 23.4~30 Gy). The dose of the first course 3DCRT for lesion was 30 Gy in 3 Gy per fraction. The median dose of the first course of SRS was 16 Gy in 1 fraction (range, 12~24 Gy). The median dose of the second course of WBRT was 27.5 (range, 12~30 Gy). The median dose of the second course of 3DCRT for lesion was 30 Gy (range, 25~30 Gy). The dose of the second course of SRS was 16 Gy in 1 fraction. The second course of WBRT was administered on radiographic disease progression with symptom in all patients. With median follow-up of 25 months, overall symptom resolution rates were 47.8%. Rate of palliative efficacy was 82.6% including stable disease. The median survival time after initiation of reirradiation was 3.2 months. Median value of KPS prior to reirradiation was 30. Median value of KPS after reirradiation was 60. Reirradiation of brain metastasis maybe feasible and effective in select patients with a good performance status $KPS{\geq}60$ (: ECOG 0~2) prior to reirradiation.

  • 앙드레 꾸레쥬는 자신의 디자인에 건축적 조형미를 표현한 대표적인 디자이너이다. 그의 디자인들은 라인 뿐 아니라 색채, 소재, 액세서리에 이르기까지 건물을 짓듯이 설계, 구성되어 있다. 최근 복식미의 건축적 조형성이 강조되고 있는 것을 감안할 때, 60년대 이미 선구자적인 역할을 하면서 자신의 건축가적인 기호를 유감없이 발휘해온 꾸레쥬를 연구한다는 것은 21세기를 향한 패션의 발전 측면에서 조금이라도 의미가 있지 않을까 생각한다. 본 연구에서는 앙드레 꾸fp쥬가 가장 활발히 활동했던 1974년에서 1970년까지 그의 디자인들을 집중 연구하였는데, 그의 패션디자인에 건축양식의 특징들이 어떻게 나타났는지에 연구의 초점을 맞추었다. 본 연구의 대상으로 사용된 실제의 옷 샘플들은 뉴욕 메트로폴리탄 예술박물관내의 Costume Institute Storage 에 있는 의복과 액세서리들을 직접, 관찰 , 분석한것이고 그 박의 사진들은 패션과 건축에 관한 서적과 잡지, 박물관내의 Slide Library , 그리고 Costume Institute Library Collection에서 발췌 , 비교 연구한 것이다. 일찍이 엔지니어링과 건축을 공부했던 앙드레 꾸레쥬는 50년대의 패션 디자이너의 거장 발렌시아가 밑에서 10년 넘게 일하다가 독립하였는데 그의 디자인 세계는 줄곧 여성들이 입고 편히 활동 할 수 있는 기능성을 강조하면서 단순하고 편안한 의복 구성에 중점을 두었다. 그리고 그는 이러한 자신의 패션 철학과 의복제작 과정들은 현대건물이 갖는 단순성, 기능성의 특징과 일치한다고 믿었다. A. 라인(Line) 앙드레 꾸레쥬는 패션 디자인에서의 비레는 건축에서구조를 쌓아가는 것과 같은 것이라고 생각하고 옷에서의 기본 구성을 기하학적인 라인에 두었다. 그래서 그의 옷들은 A-라인, 사각형, 사다리꼴,,, 등의 분명한 실루엣을 이루고 있는데 이러한 기본라인을 뒷받침이라도 하듯 소매가 아주 짧거나 없는 것이 특징이다. 황금분할이 아닌 1 : 1 구성은 그가 독특하게 사용한 비례방법의 하나인데 그것은 자켓과 스커트의 길이비례, 요크와 몸판간의 면적비례 등에서 잘 나타나고 있다. 그리고 그는 , 의복구성의 비례를 강조하기 위해 사용한 강한 색상의 대비를 현대건물의 인테리어에 빛을 사용하는 것과 같은 이치라고 설명한다. B.색상(Color) 흰색은 그러한 그의 비례강조 의복에 가장 적절한 색으로 사용되었다. 그는 빨강, 오렌지, 녹색, 분홍등 강렬한 원색을 사용하였는데도 불구하고 흰색은 그의 건축양식 발상의 Ideo를 완성시키는 완전한 색이었다. 뜨거운 날씨에 흰색이 가장 기능적인 색인 것처럼 강한 원색 대비를 통해 비례강조를 하면서 동시에 그것을 뒷받침하는 가장 합리적이고 기능적인 색은 흰색이라고 믿었다. C. 소재 (Material) 앙드레 꾸레쥬는 건물을 짓듯이 사람위에 옷을 건축한다고 믿었기 때문에 자연히 둔탁하고 딱딱한 소재가 많이 사용되었다. 비닐, 금속류, 시퀸스처럼 광택나고 투명한 재료 선호는 그 당시 현대 건축에서 선풍적으로 많이 사용되었던 유리, 금속류, 크리스탈 등 비치고 광택나는 건축재료와 일맥상통하는 것이다. 그러한 선국적인 내료 사용결과로 보여진 괴상하고 선정적인 그러면서도 아주 단순한 패션은 미래 지향적인 건축양식 구조의 " Simple", "Plain" 느낌과 정확하게 같은 것이다. 이상과 같이 앙드레 꾸레쥬는 옷을 디자인 했다기 보다는 건축했다. 주목할만한 점은 60년대 말 당시 발표되었던 그의 건축 구조적인 디자인의 특징들이 21세기를 앞둔 90년대에 다시 크게 유행하고있다는 점이다. 꾸레쥬 역시, 최근 자신의 디자인을 통해 건축적 조형미와 미래지향적 이미지를 더욱 강조하고 있는 것을 볼 수있다. 단순하면서 우주공간을 선회하는 듯한 입체적인 라인, 흰색을 비롯한 자연에 가까운 색을 중심으로 하되, 밝은 색조의 하이라이트, 플라스틱, 금속류와 같이 딱딱하고 광택나며 비치는 재료 사용,, 등등이 바로 그것이다. 그리고 이러한 그에 미래 지향적이고 조형적인 디자인들은 앞으로 어떻게 더 모험적인 모습으로 선보일지 우리 모두가 주목할만한 일인 것이다.

  • Silhouette Animation has been recognized as a genre of animation since the very beginning of the animation history, and also Its segmental movement and Aesthetic expression has led a variety of semantic interpretations. Especially the French animation director, Michel Ocelot, recently integrated 3-dimensional digital to the silhouettes animation, and it extended the possibility of the silhouettes animation in many aspects. In his latest animation feature, , he showed how he made changes in 3-dimension by creating and evolving his own way and style of silhouette animation. Although mainstream digital animations preferably to show realistic images and motion, Michel Ocelot used very selective movement, subjective digital colors and extended space which couldn't be expressed in the way of creating traditional style of silhouette animation. This alternative slow movement and the unique aesthetics in 3-dimension emphasize the unconscious elements of color, composition, patterns, and it provides digitally enhanced images and pictorial impression. In addition, the acquisition of digital three-dimensional use of space made possible to provides the wider formative imagination to the audience. In this paper, we analyzed aesthetic characteristics of the digital silhouette animation, (2011), specially focusing on the aspects of Movement, Image, Space, which could not be found in the traditional silhouette animation. It is significant to obtain diversity of the future digital animation and its positive development. In addition, this provides opportunity to explore Michel Ocelot's new experiments and animation philosophy.

  • The characters that could be connected to diverse cultural contents have formed diverse platforms with the development of digital technology, and the size of the relevant industry and market is rapidly growing. Recently, the utilization of character emoticons for smartphone messenger has been rapidly increased, so that the characters are settled down as a tool for non-verbal communication, on top of drawing attention as an independent area. With the expansion of character market, the importance of design that could give interest and familiarity to consumers is more emphasized. The body proportion of characters includes the implicative and symbolic meanings that could express diverse personalities. Thus, this study examined the body proportion of the characters with the high consumers' preference, and then analyzed the characteristics of formative elements of character design in accordance with the body proportion. In the results of the analysis, the exaggerated form of SD characters in two or three-head figure, and the realistic Real characters in seven or eight-head figure were preferred. For the SD characters, the colors with a high chroma showing the cute and cheerful image were used. For the Real characters, the cubic effect was expressed through the colors with active images and the light and shade of color. Even though the SD characters have limited motions due to the omitted body parts, the facial movements of animation characters are exaggerated while the Real characters describe the realistic and dynamic motions.

  • Image-based three dimensional radiation treatment planning(3D RTP) has a potential of generating superior treatment plans. Advances in computer technology and software developments quickly make 3D RTP a feasible choice for routine clinical use. However, it has become clear that an evaluation of a 3D plan is more difficult than a 2D plan. A number of tools have been developed to facilitate the evaluation of 3D RTP both qualitatively and quantitatively. For example, beam's eye view(BEV) is one of the most powerful and time-saving method as a qualitative tools. Dose-volume histogram(DVH) has been proven to be one of the most valuable methods for a quantitative tools. But it has a limitation to evaluate several different plans for biological effects of the tissue and critical organ. Therefore, there is a strong interest in developing quantitative models which would predict the likely biological response of irradiated organs and tissues, such as tumor control probability(TCP) and normal tissue complication probability(NTCP). DVH and NTCP of hepatoma were evaluated for three dimensional conformal radiotherapy(3D CRT). Also, 3D RTP was analysed as a dose optimization based on beam arrangement and beam modulation.

  • A hologram is a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation. Therefore not only can it express the three dimensional properties of the object, but because of it ability to show the depth and spatial properties of the object holograms may be a more effective tool in advertising for its visual appeal. This study presents 'hologram'a three dimensional stereo imaging, as the expression technique in advertising of the next generation, and with proper understanding of 'hologram' and of all its potential applications discusses opportunities for advertisements that are distinct from the multi media advertisements of today. The basic concept of Holograms and their application methods were presented in the thesis, and by using Sales Promotion advertisement as example, discussed what elements are required in order to produce an effective advertisement using holograms.

  • For the purpose of utilization in 3-D conformal radiotherapy and whole body radiosurgery, the Whole Body 3-Dimensional Topographic Radiation Therapy System has been developed. Whole body frame was constructed in order to be installed on the couch. Radiopaque catheters were engraved on it for the dedicated coordinate system and a MeV-Green immobilizer was used for the patient setup by the help of side panels and plastic rods. By designing and constructing the whole body frame in this way, geometrical limitation to the gantry rotation in 3-D conformal radiotherapy could be minimized and problem which radiation transmission may be altered in particular incident angles was solved. By analyzing CT images containing information of patient setup with respect to the whole body frame, localization and coordination of the target is performed so that patient setup error may be eliminated between simulation and treatment. For the verification of setup, the change of patient positioning is detected and adjusted in order to minimize the setup error by means of comparison of the body outlines using 3 CCTV cameras. To enhance efficiency of treatment procedure, this work can be done in real time by watching the change of patient setup through the monitor. The method of image subtraction in IDL (Interactive Data Language) was used to visualize the change of patient setup. Rotating X-ray system was constructed for detecting target movement due to internal organ motion. Landmark screws were implanted either on the bones around target or inside target, and variation of target location with respect to markers may be visualized in order to minimize internal setup error through the anterior and the lateral image information taken from rotating X-ray system. For CT simulation, simulation software was developed using IDL on GUI(Graphic User Interface) basis for PC and includes functions of graphic handling, editing and data acquisition of images of internal organs as well as target for the preparation of treatment planning.

  • Purpose : Three dimensional conformal radiotherapy planning is being used widely for the treatment of patients with brain tumor. However, it takes much time to develop an optimal treatment plan, therefore, it is difficult to apply this technique to all patients. To increase the efficiency of this technique, we need to develop standard radiotherapy plant for each site of the brain. Therefore we developed several 3 dimensional conformal radiotherapy plans (3D plans) for tumors at each site of brain, compared them with each other, and with 2 dimensional radiotherapy plans. Finally model plans for each site of the brain were decide. Materials and Methods : Imaginary tumors, with sizes commonly observed in the clinic, were designed for each site of the brain and drawn on CT images. The planning target volumes (PTVs) were as follows; temporal $tumor-5.7\times8.2\times7.6\;cm$, suprasellar $tumor-3\times4\times4.1\;cm$, thalamic $tumor-3.1\times5.9\times3.7\;cm$, frontoparietal $tumor-5.5\times7\times5.5\;cm$, and occipitoparietal $tumor-5\times5.5\times5\;cm$. Plans using paralled opposed 2 portals and/or 3 portals including fronto-vertex and 2 lateral fields were developed manually as the conventional 2D plans, and 3D noncoplanar conformal plans were developed using beam's eye view and the automatic block drawing tool. Total tumor dose was 54 Gy for a suprasellar tumor, 59.4 Gy and 72 Gy for the other tumors. All dose plans (including 2D plans) were calculated using 3D plan software. Developed plans were compared with each other using dose-volume histograms (DVH), normal tissue complication probabilities (NTCP) and variable dose statistic values (minimum, maximum and mean dose, D5, V83, V85 and V95). Finally a best radiotherapy plan for each site of brain was selected. Results : 1) Temporal tumor; NTCPs and DVHs of the normal tissue of all 3D plans were superior to 2D plans and this trend was more definite when total dose was escalated to 72 Gy (NTCPs of normal brain 2D $plans:27\%,\;8\%\rightarrow\;3D\;plans:1\%,\;1\%$). Various dose statistic values did not show any consistent trend. A 3D plan using 3 noncoplanar portals was selected as a model radiotherapy plan. 2) Suprasellar tumor; NTCPs of all 3D plans and 2D plans did not show significant difference because the total dose of this tumor was only 54 Gy. DVHs of normal brain and brainstem were significantly different for different plans. D5, V85, V95 and mean values showed some consistent trend that was compatible with DVH. All 3D plans were superior to 2D plans even when 3 portals (fronto-vertex and 2 lateral fields) were used for 2D plans. A 3D plan using 7 portals was worse than plans using fewer portals. A 3D plan using 5 noncoplanar portals was selected as a model plan. 3) Thalamic tumor; NTCPs of all 3D plans were lower than the 2D plans when the total dose was elevated to 72 Gy. DVHs of normal tissues showed similar results. V83, V85, V95 showed some consistent differences between plans but not between 3D plans. 3D plans using 5 noncoplanar portals were selected as a model plan. 4) Parietal (fronto- and occipito-) tumors; all NTCPs of the normal brain in 3D plans were lower than in 2D plans. DVH also showed the same results. V83, V85, V95 showed consistent trends with NTCP and DVH. 3D plans using 5 portals for frontoparietal tumor and 6 portals for occipitoparietal tumor were selected as model plans. Conclusion : NTCP and DVH showed reasonable differences between plans and were through to be useful for comparing plans. All 3D plans were superior to 2D plans. Best 3D plans were selected for tumors in each site of brain using NTCP, DVH and finally by the planner's decision.

  • The present study is about a brand development strategy that utilizes Korean traditional patterns. The global culturenomics phenomenon confirms the value of the cultural aspects of design when a national brand is established. People succeed with their unique aesthetic sense and reinterpret it in a modern view, and this design acts as today's national brands. In this way, people used traditional patterns and original designs, along with regional characteristics and formative style, in developing their designs. However, due to recent changes in the global environment, modern people live in an "untact" world, and consumption culture shifted toward online marketing. In this environment, where one is isolated from social activities, there needs to be a strong image that can dramatically change the mood of one's home. I would like to re-examine the Dan-Chung pattern, whose painting depends on the aesthetic characteristics of architecture to protect the wooden members of the framework in traditional architecture. The pattern and color of Dan-Chung, coated in traditional architecture, differs by the type of construction used, which includes a palace, a Buddhist temple, and a Confucianism Dan Chung. The Geummoon pattern contains aesthetic factors to add solemnity to the Main Buddhist Halls, which contain Buddha. This is a new medium that continues the current traditions instead of remaining in the past. Among different Dan Chung patterns, Geummoon has magnificent decoration consisting of the highest grade materials and unique composition; therefore, it is suitable to be reinterpreted in modern terms. The same pattern can be interpreted in different ways with different colors, so there is a great aesthetic impression in the Geummoon pattern. The value of preservation for exploration and theoretical study of the traditional pattern is important, but recreating the pattern into modern formative art can present a new angle of view and national brand, bearing pride in our cultural assets. The study used multidimensional molding methods for realistic presentation after going through the two-dimensional design process. The significant value of Korean molding beauty which hangs onto the past will play a crucial role in establishing our national brand.
