본 논문은 기하학적으로 왜곡된 입 모양을 보정하는 기법을 제안한다. 제안한 기법은 특징추출 단계와 보정 단계로 구성된다. 특징추출 단계에서는 원영상과 목적영상의 입술모델에 따라 각각의 특징과 특징점을 찾고 보정 단계에서는 부분 영상의 사상위치를 결정하고 어파인 변환을 적용하여 입의 왜곡을 보정한다. 여러 형태의 입모양을 실험한 결과, 많은 부분에 존재하는 왜곡이 보정된 것으로 나타났다.

In this paper we present cooperation of heterogeneous robot team, composed of a wheeled robot and a helicopter for localization and map building. This heterogeneous robot team can successfully fulfill task by combining the abilities of both robots than single robot because wheeled robot and helicopter have complementing ability. The scenario describes a tightly cooperative task, where the wheeled robot move carrying the helicopter and detect obstacles, if there are obstacles, helicopter take off for map building and land, then robot team move destination avoiding obstacles. We present PID controller for position control of helicopter and transformation algorithm to global coordinate from image pixel coordinate. Experimental result show that the proposed method is valid.

오디오 스테가노그래피는 오디오 매체(신호)에 암호화된 비밀 메시지를 은닉하여 전송하는 일반적이고, 폭넓게 이용되는 통신기법이다. 인간은 청각시스템의 지각능력의 한계 때문에 커버 오디오 파일과 스테고 오디오 파일의 지각품질(perceptual quality) 차이는 없다. 또한 공격자로부터의 안전성과 견고성 측면에서 LSB 기법은 디지털화된 오디오 신호에 메시지를 삽입하는 효율적이고, 경제적인 방법으로 널리 이용되고 있다. 이 논문에서는 LSB 기법을 기반으로 하고, 디지털화된 비밀 메시지의 비트별 위치를 변경하고, 암호화한 후 커버 오디오 매체에 은닉하는 개선된 방법을 제시한다.

When people go to travel, sometimes one writes many articles about the destination. Existing travel information services such as Blog, Internet Cafe, and SNS are difficult to provide realistic information since the provided information may not be a place directly on the road. This paper presents a travel information system including recommended courses, theme courses, and travel map. In addition, the proposed system can provide the functions of writing, reading, and deleting a message note that stores the travel information based on the augmented reality if a defined marker among the community members is recognized in a smartphone App. Therefore, this paper can present an implementation method for new community system using augmented reality and image processing as well as providing the conventional travel information services, and allows the user to take advantage of the realistic and accurate information.

Gamut mapping is a technique that acts on cross-media color reproduction to transform a color between devices for the purpose of enhancing the appearance or preserving the appearance of an image. Gamut mapping essentially produces color conversion error which depends the gamut mapping method, source and destination devices, and sample points for gamut modeling. For color space conversion between monitor colors and printer colors, empirical representation using sample measurements is currently widely utilized. Color samples are uniformly selected in the device space such as CMY or RGB, represented as color patches, and then measured. However, in the case of printer, these color samples are not evenly distributed inside the printer gamut and the color conversion error is increased. Accordingly, this paper introduces a equally distributed color sampling method in CIELAB space, a device- independent color space, to reduce color conversion error, and the performance is analyzed via color space conversion experiments using tetrahedral interpolation.

In this paper, we implemented the autonomous mobile robot which can recognize and avoid obstacles, then move to its destination using a camera and ultrasonic sensors. The mobile robot can avoid both stationary obstacles with a camera and moving obstacles with ultrasonic sensors. It can find the self-location with the map-based system, that is, it attempts to localize by collecting sensor data, then updating some belief about its position with respect to a map of the environment.

Theatricals have been with human's history for a long time. And It is also receiving a lot of love in modern times. The stage is recognized another space of time by spectators during the play and the production actualize fictional world by using all destination things on the stage. Therefore, the design of the stage has symbolism and the production needs semiological. The Elements expressed through the stage is composed of stage equipment, costume, lighting, stage effects and the production needs light, sound and costume designers, a stage manager, grips an advertising director for the play. The study analysis on symbolic image on the view of semigical with focused on "Vishnvovvi sad" of Anton Chekhov. The details of the study are symbolism of stage effect and costume, lighting, stage equipment. Furthermore, The study analyze way to symbolic Express korean characteristics and This research is an excellent source for students who are studying the semilogical analysis of stage.

Using the artificial sun, namely the BIOSUN, we can control the sun light according to the latitude and longitude and for the seasonal changes and apply that to subway stations. By doing this, we can expect three effects, a. allowing the plants to grow inside the stations which will in turn contribute to improving air purity, controlling humidity, and reducing dust for pleasant environment, b. pleasant environment will foster positive emotional responses of the passengers and that would increase the satisfaction, and c. fostering good service for the citizenry and establishing an environmental friendly image of the Seoul Metro Subway System. The purpose of this thesis paper is to contemplate on the uses of the artificial sun powered by the microprocessor of a Light Emitting Diode (LED) in controlling the light and how the light can be utilized in facilitating photosynthesis that would allow plants to grow inside subway stations.

From the migrant care-workers arriving in Japan from the Philippines and Indonesia to support the depleted social support system for the large population of the elderly (Ogawa 2012) to the increasing number of retiring Japanese embarking on long-stay tourism in Malaysia (Ono 2015), the Japanese image of Southeast Asia as an exotic destination offering cheap labor in return for official development assistance seems to be fading away. Yet these changes are not necessarily reflected in the way contemporary Japanese, especially those who belong to the global, "spiritual-but not-religious" (Fuller 2001) population, think of and "consume" Southeast Asia in their daily lives. Using three case-studies, spiritual tours, Thai massage, and an NGO founded by a Japanese spiritual therapist, this paper argues that in Japan's large spiritual market, which targets people seeking alternative ways to express their religiosity, the old-fashioned colonial exoticism of Southeast Asian narratives were integrated in a totalizing discourse, in which Japan remains the exceptional outlier (Tanaka 1993), a country still claimed to be "advanced" both spiritually and economically.

본 연구는 산업생산의 시대가 가고, 문화생산 시대가 도래하며 융복합시대로 접어들고 있는 시점에서 점차 문화마케팅의 중요성이 늘어나며, 이를 브랜딩에 적용해 성과를 올리고 있다는 점에서부터 시작되었다. 본 연구의 목적은 관광분야에서 융복합적 성격의 마케팅 전략으로 활용되는 문화마케팅요인이 브랜드 태도 및 인식에 미치는 영향에 대해 밝히는 것이다. 따라서 본 논문은 방한 중국관광객을 대상으로 하여 문화마케팅요인에 따른 세분집단별 관광지 브랜드 자산 및 태도 연구를 시도하였다. 연구결과 및 내용은 다음과 같다. 첫째, 선행연구를 통해 연구의 기반을 마련하고, 문화마케팅 요인을 확인할 설문지 작성 및 배포와 분석을 통해 해당 집단을 저관여인식집단, 고관여인식집단, 중관여인식집단 총 3개로 군집화하였다. 둘째, 세분시장별 브랜드 태도를 확인한 결과 관광지 브랜드 태도는 유의한 차이를 보이며, 특히 군집 2가 높은 값을 보이고, 군집 3은 보통으로 나타났다. 셋째, 각 세분시장별 브랜드 자산인식의 차이에서는 관광지 지각된 품질, 브랜드 인지도, 브랜드 이미지 모두 통계적으로 유의한 차이를 보이며 기존 선행연구를 지지하며 본 연구의 가설로 채택되었다. 이러한 연구결과를 바탕으로 본 논문은 문화마케팅의 관광 분야 적용이 적고, 관광지 대상으로 확대가 필요한 시점에서, 요인에 따라 시장을 세분화했다는 특징을 가지며, 각 세분 시장별 브랜드 태도와 자산에 미치는 영향을 분석하여 이론 및 실무적 시사점 측면에서 의미를 제시할 수 있을 것으로 기대한다.
