Background and Objectives : Boundary detection and drawing are essential in 3D reconstruction of neck mass. Manual tracing methods are popular for drawing head and neck tumor. To improve manual tracing, circular boundaries overlapping was tried. Materials and Methods : Twenty patients with neck tumors were recruited for study. Representative frames were examined for shapes of outline. They were all single closed curves. Circular boundaries were added to fill the outlines of the tumors. Inserted circles were merged to form single closed curves(Circular boundary overlapping, CBO). After surface rendering, 3 dimensional images with volumes and area data were made. Same procedures were performed with manual tracing from same cases. 3D images were compared with surgical photographs of tumors for shape similarity by 2 doctors. All data were evaluated with Mann-Whitney test(p<0.05). Results : Shapes of boundaries from CBO were similar with boundaries from manual tracing. Tumor outlines could be filled with multiple circular boundaries., While both boundary tracing gave same results in small tumors, the bigger tumors showed different data. Two raters gave the similar high scores for both manual and CBO methods. Conclusion : Circular boundary overlapping is time saver in 3 dimensional reconstruction of CT images.

Old Russian Legation(1890) has been attracted public attention in terms of politics and foreign affairs than architectural style because of conditions of location and historical incident. Though it was heavily damaged during the Korean war, and only the tower has been restored, it is very important in architectural history in Korea, because it is the oldest western style brick building which is existing with the old bishop's house in Myeong-Dong. But it has been impossible to reveal exactly the original form as there has been few reliable materials(picture, drawing, document) and it's remains were nearly destroyed owing to development of the surroundings. Recently the decisive document(site outline map) was found, and new research on the architect Sabatine was studied. So I can get into close with the original form by the results. In this study, I tried to conjecture the original form of the old Russian legation(the size, style, plan and indoor space, arrangement of attached facilities) and I checked the location and structure of the room where King Gojong stayed when he took refuge, and the use of the passage in the basement.

The current paper examines the role of the identity of entrepreneurs in the emergence and evolution of a new organizational form by empirically analyzing the evolution of eBook publishers in Korea from 1996 to 2011. Drawing on the recently developed identity-based theory of organizational form in the organizational ecology literature, we test hypotheses on the effects of focused and diffused organizational identities on organizational founding in an emergent organizational population. The results of our empirical analysis that tested three hypotheses about a positive relationship between focused identity and form emergenceand negative relationships between diffused (horizontal and vertical) identity and form emergence largely supported the argument of identity-based entrepreneurship. General implications are discussed.

The costumes (including mask) of the first World Master series of The National Changguk Company of Korea, Achim Freyer's 'Mr. Rabbit & Dragon king' is directly designed by Achim Freyer who was in charge of direction and stage design. The new form called Pansori opera is proposed for modernization of Korean traditional opera, it maintained the original form of music yet introduced play form of opera. The costumes and stage also promoted modernistic transformation while maintaining the original Korean form. The overall concept of 'Mr. Rabbit & Dragon king' costumes emphasizes comical effect by abstractness like childlike scribble. It expressed characteristic of characters diversely through exaggeration and expansion while maintaining original form of Hanbok, used surface of costumes as a drawing board, and created flat and geometrically transformed silhouette. The complicated characters was caricatured like everyone is doing mask play by using masks, and it still maintained sophisticated oriental color with modern application of five cardinal colors. It may seems it just mixed our traditional elements like a hint of humor, however, it could be known that it introduced various techniques in it to deliver new subject while maintaining the original form of 'Mr. Rabbit & Dragon king'. From this study, open mind for our tradition and need for diverse attempt could be rediscovered and could also see the possibility to contribute on creating a Nation Brand of traditional performing art.

This study is the process of performing the interdisciplinary fusion study between multiple fields by identifying the status on the previous artistic education considering the brain scientific mechanism of image creativity and brain-based learning principles. In recent years, producing the educational methods of each field as the fusion study activities are emerging as the trend and thanks to such, the results of brain-based educational fusion studies are being presented for each field. It includes artistic fields such as music, art and dance. In other words, the perspective is that by understanding the operating principles of the brain while creativity and learning is taking place, when applying various principles that can develop the corresponding functions as a teaching method, it can effectively increase the artistic performance ability and creativity. Since the animation drawing should be able to intuitively recognize the elements of movement and produce the communication with the target beyond the delineative perspective of simply drawing the objects to look the same, it requires the development of systematic educational method including the methods of communication, elements of higher cognitive senses as well as the cognitive perspective of form implementation. Therefore, this study proposes a literature study results on the artistic education applied with brain-based principles in order to design the educational model considering the professional characteristics of animation drawing. Therefore, the overseas and domestic trends of the cases of brain-based artistic education were extracted and analyzed. In addition, the cases of artistic education studies applied with brain-based principles and study results from cases of drawing related education were analyzed. According to the analyzed results, the brain-based learning related to the drawing has shown a common effect of promoting the creativity and changes of positive emotion related to the observation, concentration and image expression through the training of the right brain. In addition, there was a case of overseas educational application through the brain wave training where the timing ability and artistic expression have shown an enhancement effect through the HRV training, SMR, Beta 1 and neuro feedback training that strengthens the alpha/seta wave and it was proposing that slow brain wave neuro feedback training contributes significantly in overcoming the stress and enhancing the creative artistic performance ability. The meaning of this study result is significant in the fact that it was the case that have shown the successful application of neuro feedback training in the environment of artistic live education beyond the range of laboratory but the use of the machine was shown to have limitations for being applied to the teaching methods so its significance can be found in providing the analytical foundation for applying and designing the brain-based learning principles for future animation drawing teaching methods.

This research is aimed at examining the characteristics of the fun fashion design in the emotional consumption era from a broad perspective, and it is meaningful in the sense that it presents the ideal direction for the development of fashion products that can satisfy the changing desires of the consumers today and tomorrow. For this, the documentary study and practical case study have been executed. This paper examined the two aspects of the fun definition when it comes to the characteristics of the fun fashion design that are manifested in the emotional consumption era. First, fun fashion design that is presented by designers from the consumers' position manifests in the form of deviation from the every day life rules, use of the child-like expression mediums and unexpected turning, fun fashion design when it pertains to the deviation from the every day life rules is expressed freely, adopts object and forms it, and mixes in the alien elements, fun fashion design when it pertains to the use of child-like expression element is manifested in the form of child-like expression, child-like expression of the form, child-like drawing, introduction of the child-like object, character and graffiti. Moreover, fun fashion design of the unexpected turn is expressed with illusion and storytelling. Next, fun fashion design from the participants' position is a design created by the active participation of the consumers. As the producers who participate actively in the product design process, design is modified by the design of participation and users so that the users can enjoy it. Likewise, it is manifested in the form of design of participation.
