This study investigated how the visual and verbal presentation format of haptic information on apparel products in online stores affects consumers' imagery information processing. This includes the quantity and vividness of mental imagery, the ease of evoking mental imagery, and the evocation of imagination imagery. Additionally, the study explored consumer satisfaction with the information and online store. The study also tested a conceptual model to examine the effects of three imagery types on imagination imagery (as elaborated imagery) and how this imagination imagery affects consumer satisfaction. Employing a 2 × 3 × 2 between-subjects factorial design, twelve one-page websites were created for the experiment. 528 women in their 20s and 30s were randomly assigned to one of the 12 treatment conditions and answered the questionnaire. The results demonstrated significant differences in the three types of mental imagery, consumers' evocation of imagination imagery, and their satisfaction with information and online stores based on presentation format. The SEM analysis revealed that the quantity and vividness of mental imagery influenced the evocation of imagination imagery, affecting consumers' satisfaction with the information. These findings suggest that online retailers must provide close-up pictures or descriptive text of apparel products to elicit positive consumer responses.

Recently, in Korea, recognizing the importance of satellite imagery and a national project, the development of satellite providing satellite imagery information of 1m high resolution has been carried out. As the application of satellite. imagery information is expanded to the national land, the environment and geographical information, etc, the necessity of integrated management of satellite imagery information increases. Unfortunately, in case of Korea, currently, the results that institutes for satellite imagery processing produce with satellite imagery have been individually managed. Integrated Management of Satellite Imagery Information project which is being promoted by ETRI (Electronics and Telecommunication Research Institute) in Korea will provide the solutions for the above mentioned problems. In this research work, we designed standard metadata for integrated management of satellite imagery information in consideration of international and national standard.

이 연구에서는 중학교 1학년 과학영재들의 비유 만들기의 각 단계에서 나타나는 심상적 사고의 특성을 심상적 정보처리 과정의 측면에서 분석하였다. 연구 결과, 과학영재들의 비유 만들기 과정에서 이미지 산출, 이미지 조작, 이미지 표현의 심상적 정보처리 과정이 나타났다. 또한, 과학영재들은 비유 만들기 과정에서 지각 심상, 기억 심상, 상상 심상의 세 가지 유형의 심상을 활용하는 것으로 나타났으며, 활용한 심상의 유형에 따라 심상적 정보처리 과정에 차이가 있었다. 이를 바탕으로 비유 만들기에서 활용한 심상의 유형에 따른 심상적 정보처리 모델을 제안하였다. 이 연구의 결과는 비유적 사고와 심상적 사고의 상호 작용을 강조함으로써 과학영재의 심상적 사고를 촉진할 수 있는 비유 만들기 전략의 효과적인 활용 방안을 마련하는데 유용한 시사점을 제공할 수 있을 것이다.

Change Detection is a useful technology that can be applied to various fields, taking temporal change information with the comparison and analysis among multi-temporal satellite images. Especially, Change Detection that utilizes high-resolution satellite imagery can be implemented to extract useful change information for many purposes, such as the environmental inspection, the circumstantial analysis of disaster damage, the inspection of illegal building, and the military use, which cannot be achieved by low- or middle-resolution satellite imagery. However, because of the special characteristics that result from high-resolution satellite imagery, it cannot use a pixel-based method that is used for low-resolution satellite imagery. Therefore, it must be used a feature-based algorithm based on the geographical and morphological feature. This paper presents the system that builds the change map by digitizing the boundary of the changed object. In this system, we can make the change map using manual or semi-automatic digitizing through the user interface implemented with a floating window that enables to detect the sign of the change, such as the construction or dismantlement, more efficiently.

Imagery and gridded data can be used as the sources of extracting important information and data layers in utilizing GIS. The existing metadata standard to distribute and to utilize the geographic information are mainly concentrated at the vector data and do not provide metadata components for imagery and gridded data. In this study, metadata components for imagery and gridded data have been investigated. Firstly, existing international metadata standards such as ISO and domestic standards of TTA have been analyzed. Based on th results, the draft metadata for imagery and gridded data have been proposed as the extensions of domestic metadata standard distribution. The draft metadata could contribute to build the basic standards to access and utilize proper imagery and gridded data fit to various application field, and this will be fundamental bases for activating GIS in public and private sectors.

RFM is the sensor model of IKONOS imagery for end-users. IKONOS imagery vendors provide RPC (Rational Polynomial Coefficients), Ration Function Model coefficients for IKONOS, for end-users with imagery. So it is possible that end-users obtain geospatial information in their IKONOS imagery without additional any effort. But there are requirements still fur rigorous 3D positions on RPC user. Provided RPC can not satisfy user and company to generate precision 3D terrain model. In IKONOS imagery, physical sensor modeling is difficult because IKONOS vendors do not provide satellite ephemeris data and abstract sensor modeling requires many GCP well distributed in the whole image as well as other satellite imagery. Therefore RPC modification is better choice. If a few GCP are available, RPC can be modified by method which is introduced in this paper. Study on evaluation modified RPC in IKONOS reports reasonable result. Pseudo GCP generated with vendor's RPC and additional GCP make it possible through sequential solution.

Recently, spatial information technologies using remotely sensed imagery and functionality of GIS (Geographic Information Systems) have been widely utilized to various types of transportation-related applications. In this study, extraction programs of some practical indices, to be effectively used in transportation reference planning problem, were designed and implemented as prototyped extensions in GIS development environment: traffic flow estimation (TFL/TFB), urban rural index (URI), and accessibility index (AI). In TFL/TFB, user can obtain quantitative results on traffic flow estimation at link/block using high-resolution satellite imagery. Whereas, URI extension provides urban-rural characteristics related to road system, being considered one of important factors in transportation planning. Lastly, AI extension helps to obtain accessibility index between nodes of road segments and surrounding district areas touched or intersected with the road network system, and it also provides useful information for transportation planning problems. This approach is regarded as one of RS-T (Remote Sensing in Transportation), and it is expected to expand as new application of remotely sensed imagery.

In this paper we present a method of feature extraction for motor imagery single trial EEG classification, where we exploit nonnegative matrix factorization (NMF) to select discriminative features in the time-frequency representation of EEG. Experimental results with motor Imagery EEG data in BCI competition 2003. show that the method indeed finds meaningful EEG features automatically, while some existing methods should undergo cross-validation to find them.

Efficient extraction and update of imagery is a crucial element in establishing latest geospatial information in today's fast changing Information society. Provision of Quick Bird imagery, with 61cm resolution panchromatic imagery and 2.5m resolution multi-chromatic imagery is contributing greatly in the application field if high density geospatial information. This research have conducted digital plotting utilizing stereo images provided by QuickBird satellite and evaluated the accuracy through comparison and analysis with digital map results. It turned out that result has smaller error than standard deviation of scale of 1:5,000 set by the NGII. This proves that the production of digital map at scale of 1:5,000 is possible.

Mean curvature diffusion (MCD) is a selective smoothing technique that promotes smoothing within a region instead of smoothing across boundaries. By using mean curvature diffusion, noise is eliminated and edges are preserved. In this paper, we propose methods of automatic parameter selection and implementation for the MCD model coupled to min/max flow. The algorithm has been applied to high resolution aerial images and the results show that noise is eliminated and edges are preserved after removal of noise.
