  • The purpose of this study is to develop a photomontage expression in order to express a characteristic personality and creativity of artists of effectively in fashion illustration. The results of this study were as follows : 1) Because of a fashion and a human body were the major subjects in fashion illustration, human body transformation and composition between a human body and heterogeneous objects by photomontage appeared with a lot of works. 2) Photomontage appeared with a parody in a truth recurrence differ from a visual art, a parody seemed to be a humor with recurrence image of the original and it appeared with the general public image and it is effective in message delivery. 3) It was a stopped screen. but photomontage was expressed through overlapping and reiteration was characteristic, and it appeared with movement. a direction, a speed and rhythm effectively. 4) One screen of general chapter was only to express limited meaning, but after screen of a lot of chapter, it was able to express that was borrowed and reconstructive with a lot of contents or different contents are more than before. 5) It is changed, and composited images have a multiple point of time, and it extend a space-time limit, visual limit and an expression enabled a multidimensional space-time. Moreover, photomontage neglects unique sincerity and fact of a photo by development and utilization of computer graphic. and it can get a screen effect to spread in the virtual world as abstraction and hyper-reality. Therefore, if various photomontage expression apply to fashion illustration works, it can overcome a limit of a visual expression. and it is able to become an important way for expanding a filed of expression and enhancement of a practical function gradually in fashion illustration

  • The purpose of this study was to investigate the images and characteristic formative elements of Korean traditional patterns. The Korean pattern image could be interpreted into visual elements of design based on the images, the characteristic formative elements of Korean traditional patterns, and their relationships. Fourteen patterns selected from 5 groups of Korean patterns were used as stimuli. An image evaluation using a 2-point sementica scale of 19 bipolar adjectives, and an impression evaluation of which results were presented by visual drawing using lines and shapes were carried out. The data were analyzed by correspondence analysis and cluster analysis. The major findings are as follows; 1. Fourteen patterns and 19 adjectives were marked on a perception map composed of two (x and y-) axes. The bipoles of x- and y axes were soft-hard and splendid-artless, respectively. 2. Four clusters semerged to account for the dimensional sturucture of 14 patterns and 19 adjectives. These were splendid image, soft image, individualistic image, and sophisticated image. However there was no pattern which belonged to the cluster, sophisticated image. The Korean pattern image was founded to be better related to the kind of patterns than the type of patterns. 3. The characteristic formative elements obtained from the impression test were contour of motif, repeated line or shape, various curved lines, and decorative elements. 4. The splendid image was related to Bongwhang patterns and detailed line and complexity. The individualistic image was related to the abstractive form of Bongwhang pattern and the decorative form of Cloud pattern both of which have the characteristics of point-symmetry and abstraction, and Turtle-back pattern. In this case, the related charac-teristic formative element was identified to be repeated lines. The soft image was related to Moran, Cloud, and Taegeuk patterns. The related characteristic elements were various types of curved lines, decorative elements, and rounded contours.

  • Background: Whether depression causes increased risk of the development of breast cancer has long been debated. We conducted an updated meta-analysis of cohort studies to assess the association between depression and risk of breast cancer. Materials and Methods: Relevant literature was searched from Medline, Embase, Web of Science (up to April 2014) as well as manual searches of reference lists of selected publications. Cohort studies on the association between depression and breast cancer were included. Data abstraction and quality assessment were conducted independently by two authors. Random-effect model was used to compute the pooled risk estimate. Visual inspection of a funnel plot, Begg rank correlation test and Egger linear regression test were used to evaluate the publication bias. Results: We identified eleven cohort studies (182,241 participants, 2,353 cases) with a follow-up duration ranging from 5 to 38 years. The pooled adjusted RR was 1.13(95% CI: 0.94 to 1.36; $I^2=67.2%$, p=0.001). The association between the risk of breast cancer and depression was consistent across subgroups. Visual inspection of funnel plot and Begg's and Egger's tests indicated no evidence of publication bias. Regarding limitations, a one-time assessment of depression with no measure of duration weakens the test of hypothesis. In addition, 8 different scales were used for the measurement of depression, potentially adding to the multiple conceptual problems concerned with the definition of depression. Conclusions: Available epidemiological evidence is insufficient to support a positive association between depression and breast cancer.

  • 본 연구는 3D캐릭터 개발에 효율성을 높이고, 보다 인간의 표정에 가까운 캐릭터표정을 제작하기 위하여 실시되었다. 각 연령층별, 성별, 직위 등의 계층으로 각 감정영역을 데이터화하여 하나의 시스템으로 연동되어진다면 애니메이션, 만화, 연기 및 다양한 영상 엔터테인먼트산업과 이에 필요한 인력양성에 고무적인 반향을 일으킬 수 있을 것으로 사료된다. 이에 그 기반연구로 실시된 선행 연구를 바탕으로 이번 연구에서는 연구영역 중 1개 계층 8대 감정영역에 대한 표본연구로 진행하였다. 이로써 인간의 감정과 표현 간에는 일련의 연계성이 존재하며, 특히 표정에서 나타나는 비언어적 감성기호들을 범주화할 수 있다는 가정을 증명할 수 있었다. 그러나 인간의 풍부한 감정은 하나의 자극에 대한 단일감정보다는 다수 또는 지속자극에 대한 복합기호로서 표출되므로 이에 대한 통제는 많은 어려움이 있고, 본 연구에서 제시한 연구 모델은 각 영역별, 척도별 단일 감정에 대한 내용만을 다루기 위해 실험환경을 일부 조작하였다. 본 연구의 결과는 다양한 미디어제작에 필요한 가상캐릭터의 표정, 의인화 등을 위한 주요한 데이터로 활용가능하며, 향후 연구에서는 더 많은 표본에 대한 폭넓은 데이터베이스 구축과 상대적 비교검증이 이루어져야한다.

  • To obtain good summarization algorithms, we need first understand how people summarize videos. 'Semantic gap' refers to the gap between semantics implied in video summarization algorithms and what people actually infer from watching videos. We hypothesized that ERP responses to real time videos will show either N400 effects to topic-irrelevant shots in the 300∼500ms time-range after stimulus on-set or P600 effects to topic-relevant shots in the 500∼700ms time range. We recruited 32 participants in the EEG experiment, asking them to focus on the topic of short videos and to memorize relevant shots to the topic of the video. After analysing real time videos based on the participants' rating information, we obtained the following t-test result, showing N400 effects on PF1, F7, F3, C3, Cz, T7, and FT7 positions on the left and central hemisphere, and P600 effects on PF1, C3, Cz, and FCz on the left and central hemisphere and C4, FC4, P8, and TP8 on the right. A further 3-way MANOVA test with repeated measures of topic-relevance, hemisphere, and electrode positions showed significant interaction effects, implying that the left hemisphere at central, frontal, and pre-frontal positions were sensitive in detecting topic-relevant shots while watching real time videos.

  • The purpose of this study is to suggest more specific method to express art connected to the factor of fashion design by classifying fashion case combined with contemporary art, which is expressed through visual factor of fashion, analyzing exchange phenomenon, trend and change aspect of art and fashion and researching its expression type under the background of art preference phenomenon of contemporary art. From the result of measuring the frequency of contemporary art type, it was found that various types and artists' works were applied to fashion industry. Therefore, the scope of contemporary art, which is used for fashion, is being enlarged and new type is appearing every year continuously. Especially, its frequency was highest in 2008 S/S. In addition, it was found that it was more frequent in S/S season rather than in F/W season. From the result of analyzing expression method of contemporary art inspiration shown in fashion by classifying it into structure aspect, print aspect and 3D decoration aspect, in most cases, the contemporary art was used as a print or pattern for dress or accessory. The print aspect could be divided into geometric abstraction pattern, expressional abstract pattern, trompe-l'oeil pattern, graffiti pattern, picture image pattern and cartoon pattern in detail.

  • A design for the front section of an excavator requires kinematic and kinetic mechanism consideration for several configurations. Key parameters for an appropriate configuration can be obtained through a mechanical verification and numerical formulation with a design expert's know-how. In this paper, we propose a knowledge-based system with an expert-shell(CATIA) and Visual Basic to assist for the design of the front section of an excavator. The designers can achieve more efficient design through a CAD model, implemented design knowledge, and a user friendly interface. The implemented design knowledge is retrieved through the whole design process from an early design stage to a detailed design stage based on the multiple levels of abstraction scheme.
