이미지는 오늘날 커뮤니케이션 행위를 지배하고 그 구성원의 사고 구조와 방식에 영향을 미친다. 이러한 현상은 TV 등 다양한 영상매체의 등장으로 가속화되었으며$^1$ 시각 커뮤니케이션이 갖는, 언어문화권을 뛰어넘는 의미의 보편성과 순간적인 의미 전달성이라는 기능적 속성으로 인해 급격히 진행되었다. (중략)

In most database systems images have been indexed indirectly using related texts such as captions, annotations and image attributes. But there has been an increasing requirement for the image database system supporting the storage and retrieval of images directly by content using the information contained in the images. There has been a few indexing methods based on contents. Among them, Pertains proposed an image indexing method considering spatial relationships and properties of objects forming the images. This is the expansion of the other studies based on '2-D string. But this method needs too much storage space and lacks flexibility. In this paper, we propose a more flexible index structure based on kd-tree using paging techniques. We show an example of extracting keys using normalization from the from the raw image. Simulation results show that our method improves in flexibility and needs much less storage space.

A remote sensing technique to identify trajectories of breaking waves in the surf zone using oblique digital nearshore videos is proposed. The noise arising from white foam induced by wave breaking has hindered accurate remote sensing of wave properties in the surf zone. For this reason, this paper focuses on image processing to remove the noise and wave trajectory identification essential for wave property estimation. The nearshore video imagery sampled at 3 Hz are used, covering length scale(100 m). Original image sequences are processed through image frame differencing and directional low-pass image filtering to remove the noise characterized by high frequencies in the video imagery. The extraction of individual wave crest features is conducted using a Radon transform-based line detection algorithm in the processed cross-shore image timestacks having a two-dimensional space-time domain. The number of valid wave crest trajectories identified corresponds to about 2/3 of waves recorded by the in-situ sensors.

The affective words on photographic images were analyzed and a model was structured. Based on this model, the effects of color on the affections were studied. In study 1, the photographic images with various materials and techniques were presented and the affective responses are collected. The factor analysis using principal axing method showed that the variance of the affective words could be explained about 42％ by the three factors. These are named positive-negative, dynamic-static, light-heavy, respectively. In study 2, the effects of color on the affections were evaluated on three basic dimensions. Ninety representative color images were converged black-and-white images, and each of 180 images was rated on the three affective scales. The t-test showed that the effects of color are statistically significant on the three affective scales, respectively. The achromatic images were felt more negative, more static, and heavier than chromatic images.

이미지를 보호하기 위한 보안 수단으로는 크게 워터마킹, 스테가노그래피 기법 등이 있다. 그 중 워터마킹 기법은 배경 이미지 위에 사용자가 워터마크로 사용하기 위해 원하는 텍스트나 이미지를 새겨 다른 사람이 사용했을 때, 새겨둔 워터마크를 통해 저작권 등을 증명할 수 있는 용도로 사용하여 이미지를 보호하는 기법이며, 워터마크의 속성에 따라 텍스트 워터마킹, 이미지 워터마킹으로 나뉜다. 본 논문에서는 워터마킹 기법을 이용한 이미지 생성 시, 워터마크 대상 텍스트나 이미지의 크기 및 배치 등을 알맞게 설정하는 방법을 제시하였다. 워터마크 대상의 크기를 배경 이미지에 알맞게 자동으로 조절해 주거나 사용자가 임의로 지정하도록 하여 더욱 자유롭고 효과적인 워터마킹 기법을 구현하였다.

Recently the sales of PB products attribute shows a steady growth day by day. The consumers buy them due to low prices, however, lately they buy the high premium PB products. And thus the large distributors made a rapid growth of sales. The aim of this study is to analyze what the PB products attributes may affect the consumers' purchase behavior. First, the attribute factors of the PB products: store image, knowledge and information, quality perception, economic value etc. have effects on the consumer attitude after usage experience with PB products. Second, the consumer attitude after usage experience with PB products can have an effect on the purchase behavior. As a result of this study, the various attributes of PB products such as store image, knowledge and information, quality perception, economic value appeared to be positive effect. At the same time the attitude after buying the PB products showed positive effects on the purchase behavior.

본 연구는 두 가지 선물상황(생일, 크리스마스)과 선물수용자(가족, 친구)에서 성별에 따라 선물 속성지각에 차이가 있는지를 밝히고자 하였다. 질문지를 이용하여 미국 남녀 비자 97명을 대상으로 자료수집 하였으며, 자료분석을 위해 MANOVA(Multivariate Analysis of Variable)를 실행하였다. 분석결과, 가족과 친구를 위한 생일선물상황에서 성에 따라 쾌락적 속성(독특한, 유행하는, 재미있는)의 중요성 지각에 차이를 보여 여성이 남성보다 선물의 쾌락적 속성을 더 중요하게 지각하였다. 또한 가족과 친구를 위한 크리스마스 선물상황에서도 성별에 따라 쾌락적 속성에 차이를 보여 여성이 남성보다 가족을 위한 선물로써 독특한, 유행하는 속성을 더 중요하게 지각하고, 친구를 위한 선물은 독특한, 재미있는 속성이 더 중요하게 지각되었다. 그러나 실용적 속성(내구성있는, 실용적인, 비싸지 않은)에서는 두 가지 상황의 가족과 친구를 위한 선물지각에 대해 성별에 따라 유의한 차이를 보이지 않았다. 따라서 본 연구결과. 소비자들은 선물구매상황에서 일반제품과 달리 쾌락적 가치를 더욱 중요하게 인식하고 있으며, 성별에 따라 선물 상황과 수용자에 대한 선물의 쾌락적 속성지각에 차이를 나타냄으로써 성별에 따른 차별화된 선물상품개발 및 이미지 포지셔닝 전략을 통해 효과적 마케팅 관리가 이루어져야 할 것이다.

The purpose of this study was to find out the effects of the accord between consumers benefit factors and attribute factors of brand image on brand attitude. This study was based on Kellers conceptualizing model of brand image. The subjects were 605 working women in their twenties living in Seoul, Korea. The data were analyzed by Euclidian distance model, ANOVA of repeated measures, regression, F-test by Extra Sum of Squares Principle. The results were as follows. 1. There were significant differences among the brands and among the segmented groups in the accord between benefit factors and attribute factors of brand image and in the brand preference. Moreover there were significant interactions between the brands and the segmented groups in the accord between benefit factors and attribute factors of brand image and in the brand preference. 2. There were significant effects of the accord between benefit factors and attribute factor of brand image on brand attitude. 3. There were significantly different effects of the accord between benefit factors and attribute factors of brand image on brand attitude among the segmented groups.

This paper suggests that the relationship between store images and store loyalty is moderated by store-type (online vs. offline). Data was collected from 341 online panel survey on four online stores and four offline stores. Regression analysis with interaction terms demonstrates that assortment and service among image attributes interact with store-type. Specifically, assortment is more important for offline store loyalty where as service is more important for online store loyalty. The authors discuss the implications of these findings and offer directions for future research.
