This study introduces an interactive drawing system, a tool that allows user to sketch and draw with his own intentions. The proposed system enables the user to express more creatively through a tool that allows the user to reproduce his original idea as a drawing and transform it using his body. The user can actively participate in the production of the artwork by studying the unique formative language of the spectator. In addition, the user is given an opportunity to experience a creative process by transforming arbitrary drawing into various shapes according to his gestures. Interactive drawing systems use the segmentation of the drawing image as a way to extend the user's initial drawing idea. The system includes transforming a two-dimensional drawing into a volume-like form such as a three-dimensional drawing using image segmentation. In this process, a psychological space is created that can stimulate the imagination of the user and project the object of desire. This process of drawing personification plays a role of giving the user familiarity with the artwork and indirectly expressing his her emotions to others. This means that the interactive drawing, which has changed to the emotional concept of interaction beyond the concept of information transfer, can create a cooperative sensation image between user's time and space and occupy an important position in multimedia society.

In this study, a CAD/CAM system for axisymmetric deep drawing processes has been developed. An approach to the system is based on the knowledge based system. Under the environment of CAD/CAM software of Personal Designer, the system has been written in UPL. The geometries of intermediate and final object in deep drawing process, including processes parameters are input for the CAD/CAM system. The input data can be obtained from the results of Pro-Deep. The parts drawing of die sets for each process is generatedin tool design module of the CAD/CAM system. Also, the die assemblydrawings can be obtained. NC commands for machining of the part can be generated in the developed CAD/CAM system.

The purposes of this study were to examine if there is a relationship between elderly people's anxiety towards death and their reactions to the Star-Wave drawing, and to verify if the Star-Wave drawing was a good enough tool to measure elderly people's degree of death anxiety. The subject for this study were 307 elderly people (male 127, female 180) over 60 years of age with no physical and cognitive damage, who were residing in Geongsan city and attending colleges or welfare centers for the aged. The collected data were analyzed with SPSS WIN(ver. 12.0) program, and factor analysis, correlation analysis, Chi-square test, t-test, one-way ANOVA, and $Scheff\acute{e}$ test were utilized. The results showed that factors showing different levels of anxiety towards death in the Star-Wave drawing were the total harmony of the drawing, drawing style, repetition of wave, size of the star, and location of the star. In particular, the group that drew the Star-Wave drawing with total harmony felt less anxiety towards death than the other group. Therefore, the results of this study suggested a possibility of the Star-Wave drawing to be used as a good tool that could diagnose the elderly's degree of anxiety towards death.

뉴미디어 기술을 활용한 융복합적 형태의 다양한 예술작품이 시도되는 추세를 반영하여, 본 논문에서는 공공미술의 발자취를 알아보고, 공공미술 작품의 표현방식으로 뉴미디어아트를 활용한 작품 사례들을 살펴보며, 퍼블릭 미디어아트의 새로운 도구로서 VR 드로잉을 제안한다. 이미 VR 드로잉 도구를 활용한 드로잉 퍼포먼스와 VR 실감형 공연 '허수아비'의 사례는 VR 드로잉 도구가 공공미술의 새로운 표현방식으로서의 현실 적용 가능성을 유추할 수 있다. 본 연구는 향후 뉴미디어 기술 중 VR 드로잉 도구를 활용한 예비 창작자들에게 도움이 되는 선행연구가 될 것으로 판단된다. 또한 다가오는 4차 산업혁명시대의 미디어 현황과 비교하여 예술과 기술의 미래 가치를 고민하고 분석해 본다면 의미 있는 연구가 될 것이라 생각한다.

소성가공이란 원재료를 소성변형(Plastic deformation)을 통해서 고체의 제품을 만드는 가공법이다. 가공중에 물체의 질량과 체적에는 크게 변화가 없다. 소성 가공중 주응력이 어떻게 작용하느냐에 따라서 소성가공을 여러가지로 분류하고 있다. 즉, Metal Forming은 다음과 같이 분류할 수 있다. 1) Compound Forming에는, Rolling, Free forming, Die forming, Stamping, Pressing 2) Tension compression forming에는, Drawing, Deep-drawing, Rimming, Spinning, Bulge forming 3) Tension forming에는 Lengthening, Widning, Deepening 4) Bending에는 Bending with linear tool motion, Bending with rotary tool motion 5) Thrust forming에는 Swaging, Twisting이 있다.

The purpose of this study is to trace historical changes and to show broad spectrums in landscape architectural drawing. Drawing has been both a locus of interpreting a site and a vehicle of imagining the new landscape. The designed landscape might be influenced by the way to draw in landscape design. Despite of its importance, landscape architectural drawing has rarely been discussed. Here, the drawing will be understood as theoretical issues and texts for criticism. Recently, the drawing has primarily been recognized in functional and instrumental ways. The stereotypes office drawings such as plan, section, perspective, axonometric are typical examples. Its symbolic and metaphoric dimensions have been seriously diminished. As a result, the poetic power in the designed landscape might be devastated. Composite drawing, notation are the alternative drawings to overcome the above mentioned dilemma along with the adaption of collage and photomontage. Finally, I would argue that landscape architectural drawing can be a creative tool to elicit the idea and to reveal the trace of memory. It could be also a poetic locus to postulating the vision. Designers should utilize both traditional drawing and experimental drawing in order to reconcile the instrumental representation with the symbolic representation.

For multi-stage deep drawing process including ironing operation and biaxial forming in this study, tool developments are achieved, and the developed tool sets are applied to experimental investigations. In process and tool designs, a contact condition between intermediate blank and lower die is considered as the sequential one. In this study, the material used is cold-rolled thin sheet (SPCE) with the initial thickness of 0.4mm. From the experimental approaches, several failures such as tearing, localized thickening and thinning, are observed. To solve these failures, the contact surface on the lower die is modified. As the experimental results by applying the modified lower die, it is investigated that the failures are not occurred, and the excessive deformation behavior due to the thinning and thickening effects are decreased. Furthermore, the thickness distributions on the major axis and the minor axis of each intermediate blank are investigated to be already satisfied the target (ironing) thickness, respectively. By this systematic approach, it is confirmed that the experimental results show good agreements with the designed and required configuration of each deformed and final products.
