수중 어류의 행동이나 현상을 예측하여 시각화하기 위해서는 어류의 탐지와 어류반응행동의 파악이 우선 이루어져야 한다. 수중이라는 다변적인 환경요인이 현장 계측을 매우 어렵게 하거나 어류의 행동이 비선형적으로 복잡하고 혼돈스러우므로 기존의 단순한 그래픽처리는 실제 수중현상간의 차이를 극복하지 못해왔던 실정이다. 이에 본 논문에서는 매우 복잡 다양한 어류행동반응의 패턴에 대하여 기존의 연구에서 제안된 혼돈이론을 응용한 어류반응행동 모델을 이용하여 시각화 도구를 제안함으로써 수중의 어류이동현상을 예측하거나 평가, 또는 보다 더 정확히 분석하는 자료를 얻을 수 있게 구현하였다. 아울러, 어탐 디스플레이를 동시에 적용하여 사용자에게 반응에 따르는 어류의 탐지상황도 제공하였다. 제안된 시각화 도구를 평가하기 위하여 현장 계측된 어류의 이동 정보와 비교한 결과, 제안된 시각화 도구는 사실성 높은 어류 행동과 시각적인 이해도를 높일 수 있음을 확인 할 수 있었다.

Recently, in distribution market, demand for electronic shelf label system is increasing gradually to provide the accurate price immediately and detailed product information to consumers and reduce operation costs. Most of electronic shelf label system companies develop the full-graphic display device to display a wide variety of product information as well as the exact price. Our system had introduced Go-Back-N retransmission method in the early. However, we encountered performance problems that it delayed updating of the electronic shelf label system and exhausted the battery life time. Proposed adaptive image retransmission technique based on the selective scheme is that tags of electronic shelf label system recognize idle time of transmission cycle and require partial image retransmission to sever by itself. As a result, it can acquire much more opportunities of partial image retransmission within the same period and increase reception rate of full image for each tags. The experimental result shows that adaptive image retransmission technique's reception rate of full image for each tags is approximately 4% higher than existing previous works. And total battery life time increases 30 hours because tag reduce wake-up time as it receive only lost data instead of whole data.

DGA is one of the most recent techniques developed to diagnose the fault condition on oil filled insulation transformers. There are more than 6 known different methods of DGA fault interpretation technique and so there is the likelihood that they may vary in their interpretations. A series of combined interpretation methods that can determine the power transformer condition faults in one assessment is therefore needed. This paper presents a computer program- based system developed to combine four DGA assessment techniques; Rogers Ratio Method, IEC Basic Ratio Method, Duval Triangle method and Key Gas Method. An easy to use Graphic User Interface was designed to give a visual display of the four techniques. The result shows that this assessment method can increase the accuracy of DGA methods by up to 20% and the no prediction result had been reduced down to 0%.

This study is to assist in developing creative designs based on the humor available in the fashion world of Moschino. For the research method, this writing examined literature on humor and Moschino's fashion world and analyzed Moschino's fashion collection, show window, Maison Moschino, and collaborative products to conduct an empirical analysis of humor shown to the fashion media. The research results are as follows. The humor in Moschino's fashion appeared in the form of surrealistic humor with the depaysement technique, deconstructive wit in clothing, such as distortion, change, or exaggeration, and textual humor, including brand symbols, logos, and graffiti. Collection pieces indicated the brand's confirmative identity based on humor with the surrealistic depaysement technique and deconstructive wit through irregular phenomena, such as change, distortion, exaggeration, and illusion in clothing form. Additionally, such attributes added to Moschino's wit and humor in decorative costume components as graphic images, graffiti, and brand symbols, including smile, love, and reversal. The show window display delivered surprises and smiles through the production of surrealistic space borrowed from various objects. In particular, performance with surrealistic images helped to show the characteristics of parodic humor. Maison Moschino was a surrealistic space for the concept of the fairy tale and for practical experience, thus working as a communication channel for humor and emotion. Collaborative products also clearly reflected the identity of the designer's own humor, which showed scarcity value as well as differentiation.

This paper developed motifs through the use of images of masks with which the Korean innate consciousness of aesthetics is expressed. The motifs were applied to fashion items. This paper investigated the concept, origin and types of traditional masks through the existing literature. Using the computer graphic programs of Illustrator and Photoshop CS2, three basic motifs were set from the images of the nobleman, Bune of Hahoi Tal and Byeongsan Tal. Each motif was extended into two motifs by changing shape and color. For the basic motif design, this study sought to express contemporary images, suitably for each fashion item, while maintaining the basic shape of the masks and their traditional images. In addition, this study set the concept of the design so that could be accepted by various age groups. For the design of handkerchiefs, a rotating array, involving enlargement, reduction, repetition, and the gradation of motifs, as well as a diagonal symmetric array, and all-over patterns were developed. The T-shirt design created here was divided into a half-sleeve box type, a round neckline sleeveless type, a V-neckline close-fitting sleeveless type, and a V-neckline close-fitting cap sleeve type. For the design of necklaces, OLED or LED, which are considered as a future display type, was used. Additionally, the production of an entertainment styled new atmosphere is proposed.

대부분의 교통 관리 시스템은 웹을 통한 교통정보 제공 기능을 포함하고 있으며, 지도를 기반으로 교통정보를 표출하는 방식을 채택하고 있다. 일반적으로 지도 기반의 시스템을 구현할 때에는 지리정보시스템(GIS)을 이용하는 것이 효율적이다. 하지만 많은 교통 정보 제공 시스템은 어도비 플래시 등의 그래픽/애니메이션 전문 소프트웨어를 위한 별도의 전자지도를 이용하고 있어서, 전자 지도의 변경에 유연하게 대처하기 어렵다. 본 논문에서는 이러한 문제점을 해결한 GIS 기반의 교통정보 제공 시스템을 제안한다. 제안하는 시스템은 교통정보 제공 클라이언트에서 지도 출력 엔진과 지도 데이터를 분리하고, 지도 데이터는 출력에 적합한 형태로 실시간 변환하여 전송함으로써 GIS 상에서 구축된 전자지도를 교통정보 제공 시스템에서 효율적으로 이용할 수 있도록 한다.
