This paper proposes an extraction method which extracts two different thematic maps, which have different line thickness from each other in a raster image that contains the two thematic maps. In the proposed method, the depth of each pixel is calculated according to the amount of pixels in its surrounding neighborhood, and then the thinning is performed. By using depth threshold, two thematic maps are first extracted from the thinning result. There are noise images and skeleton disconnection in the lines of each extracted thematic map. Each thematic map extraction is finally completed after removing the noise images and connecting the disconnected lines. Through the experiment, we showed that the proposed method could be used for the extraction of each thematic map of a raster image which included two thematic maps.

To complete an image, it is needed to go through the process to capture the actual actor's motion and compose it with virtual environment. Due to the excessive cost for production or lack of post-processing technology, however, it is mostly conducted by manual labor. The actor plays his role depending on his own imagination at the virtual chromakey studio, and at that time, he has to move considering the possible collision with or reaction to an object that does not exist. And in the process of composition applying CG, when the actor's motion does not go with the virtual environment, the original image may have to be discarded and it is necessary to remake the film. The current study suggested and realized depth-based real-time 3D virtual image composition system to reduce the ratio of remaking the film, shorten the production time, and lower the production cost. As it is possible to figure out the mutual collision or reaction by composing the virtual background, 3D model, and the actual actor in real time at the site of filming, the actor's wrong position or acting can be corrected right there instantly.

This paper introduce a quiz game contents based on gesture interface. We analyzed the off-line quiz games, extracted its presiding components, and digitalized them so that the proposed game contents is able to substitute for the off-line quiz games. We used the Kinect camera to obtain the depth images and performed the preprocessing including vertical human segmentation, head detection and tracking and hand detection, and gesture recognition for hand-up, hand vertical movement, fist shape, pass and fist-and-attraction. Especially, we defined the interface gestures designed as a metaphor for natural gestures in real world so that users are able to feel abstract concept of movement, selection and confirmation tangibly. Compared to our previous work, we added the card compensation process for completeness, improved the vertical hand movement and the fist shape recognition methods for the example selection and presented an organized test to measure the recognition performance. The implemented quiz application program was tested in real time and showed very satisfactory gesture recognition results.

The purpose of this study is to research the characteristics of masonry techniques on Roman ancient architecture. Opus so means masonry, has many types and techniques and still we use that word. Roman masonry technique appears to be very diverse kinds throughout to try and change the outcome of new technology. Depending on the use of materials the process can distinguished in three courses. First, just use only stones and bricks. Second is the use of concrete that is advanced to cement structure. Third is the use of air-dried bricks and grilled bricks. Roman masonry ranges of techniques not limited to the construction of the resulting but created a variety of architectural language. Architectural space is based on a comprehensive development of masonry techniques.

본 논문은 『전경』에서는 나타나는 숫자 부호 '삼(三)'의 의미와 나아가 '삼'과 『주역』 그리고 도교 신선신앙과의 연관성을 살펴보고자 한다. 중화의 문화에는 예부터 '삼'을 숭상하는 풍속이 있고, 도교문화도 '삼'을 숭상한다. 이는 주로 『주역』, 『도덕경』 및 도교 신선신앙과 관련이 있다. 한국문화는 전체적으로 중국문화의 영향을 깊이 받았다. 대순진리회 또한 이러한 배경 하에 있다고 볼 수 있다. 대순진리회에서는 '삼' 이라는 숫자를 반복해 사용하고 있는데, 어떤 의미에서 이것은 『주역』에 나타나는 부호 상징 사유의 확장된 표현이라 할 것이다. 또한 대순진리회의 교의(敎義)와 부도(符圖)에서도 '삼을 숭배하는(尙三)' 도교 신선신앙의 특징이 나타나고 있다. 그러므로 대순진리회에서 볼 수 있는 '삼'의 의미는 도교의 영향을 받은 것일 가능성이 매우 크다. 이렇게 말하는 것에는 두 가지 이유가 있는데 그 중 하나는 앞서 말한 바와 같이 대순진리회의 상제와 종도들이 중국의 서적을 이해하고 중시했기 때문이며 대순진리회의 구천상제께서 많은 종교를 통섭하였기 때문이다. 공사(公事) 활동, 부주(符呪) 문건, 상제와 도주의 행적 사료, 신령신앙 등의 내용 곳곳에서 '삼'이라는 특별한 숫자에 대한 각별한 관심이 구체적으로 드러난다. 이러한 '삼'은 생명과 시작을 나타내며 또한 완성과 완결을 의미한다. 대순진리회 신앙의 특징을 보면 그 배후에는 아주 깊은 중국문화의 영향이 있으며, 『주역』사상의 구체적인 표현이고, 도교신선신앙의 흔적이기도 하다. 물론 대순진리회는 자신만의 독창적이 재해석으로 이러한 문화나 사상을 계승하고 발전시켰다. 그렇기 때문에 '삼'이라는 숫자의 근원을 탐구하고, '삼'이 지니고 있는 철학적 사상을 파헤쳐 그 속의 오묘함을 발견한다면 대순사상의 깊을 뜻을 이해하는데 더 큰 도움이 될 것이다.

The purpose of this study is to analyze musical songs from an academic perspective by applying vocal techniques that can express songs in depth in three dimensions. Singing a musical song cannot be completed with just the musical part, rather, it should be accompanied by the analysis of various aspects such as the emotional state of the scenes and the characters. To this end, this study performed a multi-dimensional analysis of fields such as theatrical structure, lyrics, musical structure, and dynamics. In addition, the study explored and applied Estill Voice Training(EVT) that actors can best express songs with the emotions of the theater and music. EVT categorizes voice into six tones: speech, sob/cry, falsetto, twang, opera, and belting. In this study, in addition to these six sounds, the positions of vocal cords and larynx were also applied to seek ways to effectively express songs using "Gar Nichts" from the musical "Elisabeth" as a case study. "Gar Nichts" is a song sung by the protagonist Elisabeth, which expresses the self and the conflict at the peak of pain. Musically, this song requires various sound and voice-changing techniques to cover the range of "G#3-Gb5." As a result, it was confirmed that in order to embody the emotions of the characters and the songs in depth, the analysis of scenes and characters as well as various singing techniques need to be applied in harmony.
