  • This paper proposes a real-time algorithm for tracking the fast moving human body. Although Iterative closest point (ICP) algorithm is suitable for real-time tracking due to its efficiency and low computational complexity, ICP often fails to converge when the human body moves fast because the closest point may be mistakenly selected and trapped in a local minimum. To overcome such limitation, we combine a particle filter based on a motion history information with the ICP. The proposed human body motion tracking algorithm reduces the search space for each limb by employing a hierarchical tree structure, and enables tracking of the fast moving human bodies by using the motion prediction based on the motion history. Experimental results show that the proposed human body motion tracking provides accurate tracking performance and fast convergence rate.

  • 영화와 게임 산업의 융합은 최근 콘텐츠 산업 분야의 주요 이슈이다. 사실 지난 20여 년간 그 동안 둘의 융합을 위한 많은 시도가 있어왔지만, 그 결과가 성공적인 것은 아니었다. 하지만 많은 시행착오에도 불구하고 융합의 시도는 계속되어 왔고, 그 결과 근래에 이르러 두 분야의 융합이 본격적으로 이루어짐을 알리는 현상들이 나타나고 있다. 그러한 현상들 중 서사 분야에서 두드러지는 것이 '에피소드형 스토리텔링'의 증가 현상이다. 이에 따라 본 연구는 최근 영화 및 게임, 혹은 기타 여러 콘텐츠 산업에서 나타나고 있는 '에피소드형 스토리텔링' 현상에 주목하고, 이를 기존의 서사이론의 연장선 상에서 파악하는 것을 목적으로 한다. 이를 위해 영화계에서 최근 등장한 멀티 플롯 영화의 유행을 살펴보고, 에피소드식 스토리텔링의 예로 최근작인 <킹콩>의 스토리 구조를 분석하였다. 그 다음, 이러한 에피소드형 스토리텔링이 최근 주목을 받고 있는 이유를 에피소드 구성 특유의 '반복경험'에서 찾고 그것이 리스크가 높은 콘텐츠 산업에 기여하는 바가 있다는 가설을 제시하였다.

  • This paper explores the possibility of describing objects from the change in the shape according to the change in viewpoint. Specifically, we sample the shapes from various viewpoints of a 3-D model, and apply dimension reduction by locally linear embedding. A low dimensional distribution of points are constructed, and characteristics of the object are described from this distribution. Also, we propose two 3-D retrieval methods by applying the iterative closest point algorithm, and by applying Fourier transform and measuring similarity by modified Housdorff distance, and present experimental results. The proposed method shows that the change of shape according to the change in viewpoint can describe the characteristics of an object.

  • Recently construction companies expand position for apartment house in construction market because of house supply rate increase and its amount. In addition, because the focus of house sale market has moved to customer from supplier, the importance of defect management is being issued currently. However, current apartment defect management is not satisfied with customer's demand for the lack of business process management, management organization, information feedback, and readiness for defect in construction phase. To solve this problem, this study proposed business process management improvement model for defect management. Proposed improvement model make information feedback, defect management business quality improvement, and improper process improvement through integrating defect management and quality management. It is expected to contribute to customer's satisfaction improvement and reliance improvement for construction companies.

  • 3D printers, which emerged in the late 20th century, have become a key part of the fourth industrial revolution in the 21st century. Although 3D printers, the key equipment of the maker movement and the starting point of the new cottage industry in the 21st century, still reveal the limitations of mass production with low output speed and limited filament materials, the use of 3D printers by ceramic craftsmen has recently increased exponentially. However, as part of a way to overcome the discord between craftsmanship and the new technology, which has been repeated over and over in the past in craft history, the study focused on the 'plaster mold casting' technique using 3D printers. Therefore, after analyzing casting techniques of Tony Hansen, Webe van Gansbeck, Jade Crompton, and Ryu Hee-do, the potters who actively developed gypsum techniques in the world's ceramic crafts field and applied them to their own designs, I tried to find the point of convergence between 3D printers and ceramic crafts by presenting examples of effective 3D modeling methods and optimal slip casting methods using 3D printers.

A Study on the Narratives of Lee Ae-rim's Comic Books -Focusing on the Characteristics of Repetition, Coincidence, and Fantasy (이애림 만화 서사 연구 -반복, 우연, 환상의 특성을 중심으로)

  • This paper was written to investigate the narrative traits of Lee Ae-rim's Comic Books. Lee Ae-rim arrived on the scene with the boom of comic book magazines in the 1990s. Although she started her career as a Comic Book writer, she expanded her own area gradually and has been working actively as an animation director as well. The superficial characteristics of Lee Ae-rim's works can be summed up as sexuality, grotesqueness, and fantasy. In other words, Lee Ae-rim's comic books are mainly characterized by the visualization of sexual, grotesque, and fantastic shapes. Lee Ae-rim has faced challenges with her own overwhelming and compelling images like no one else. For that reason, it is true that people haven't paid careful attention to the hidden stories behind her pictures. This paper considers that looking back on the narratives that Lee Ae-rim has been interested in, from early days to recent days, that is to say, the contexts of stories, is a shortcut to reveal a point of contact between her past, present, and future. Especially, this paper focused on the properties of the circulated and repeated stories, the stories ruled by fate and coincidence, and the stories in which elements of fantasy encounter an attempt of violation. As a result, it was found that the narratives of Lee Ae-rim's comic books demand us to face suppressed desires in a new way, by wrapping up the most fundamental aspects of human being in universality and constancy with specificity and grotesqueness. The reason why Lee Ae-rim has continued the avant-garde and omnidirectional works thus far explains what our society suppresses, inversely. Moreover, the narratives of Lee Ae-rim are significant, by being devoted to the right function of art not only to disclose suppressed desires but to satisfy them. Making an in-depth investigation of the narratives of Lee Ae-rim's comic books in various contexts, this research is intended to establish a diversity of Korean comic books, by adding meaning to the creative values of individual writers.
