In this paper, we propose query restructure method which realizes not only to present the result from database in Web page but also to adapt user's browsing environments. Recently, wireless PDA (Personal Digital Assistant) and portable phone and terminals equipped with Web browser become very popular. Various browsers would be required to create the HTML which adapt to the user's browsing environment. We propose an adaptive data presentation system which is an extension of SQL which creates HTML pages dynamically adapting to the size of screen. In our proposed method, the three basic rules for the layout conversion are provided and applying these rules, an efficient layout conversion technique optimized to user environment is proposed. Moreover, we propose a standard for converting layouts and a layout optimization for adaptive conversion of layouts.

We estimate a choice-based aggregate demand model accounting for consumers' consideration sets, and study its implications on market structure. In contrast to past research, we model and estimate consumer demand using aggregate-level consumer browsing data in addition to aggregate-level choice data. The use of consumer browsing data allows us to study consumer demand in a realistic setting in which consumers choose from a subset of products. We calibrate the proposed model on both data sets, avoid biases in parameter estimates, and compute the price elasticity measures. As an empirical application, we estimate consumer demand in the camcorder category and study its implications on market structure. The proposed model predicts a limited consumer price response and offers a more discriminating competitive landscape from the one assuming universal consideration set.

Consumers often act impulsively when making internet purchases. Triggered by easy access to products, lack of social pressure, and absence of delivery impediments, impulse buying frequently occurs in the context of internet shopping. This study tests the structural equation model of the impulse buying process for fashion products when internet shopping and examines impulse buying process differences between Korean and Chinese consumers. A total of 985 usable questionnaires were obtained from college students. Data were analyzed by structural equation model analysis using a correlation matrix with a maximum likelihood by AMOS 21.0. Results showed that increased internet browsing by consumers resulted in more impulse buying as mediated by the urge to buy; in addition, more impulse buying by consumers resulted in a higher consumer satisfaction experience. Pure impulse buying created more important antecedents of satisfaction than the promotion-oriented impulse buying. Impulse buying showed a high similarity between Korean and Chinese consumers; however, increased influence from promotion activities resulted in more fashion product impulse buying for Chinese consumers versus Korean consumers. We confirm that one of the outcomes of the impulse buying process is impulse buying product satisfaction. Korean and Chinese consumers also present similarities and differences in fashion product impulse buying. A managerial implication is discussed for retailers of fashion products to develop strategies to increase consumer browsing and subsequently trigger impulse buying accompanied with consumer satisfaction.

Experiment involved range vegetation classified into three major classes: Xerophytic trees, shrubs and grasses. Among them samples of major plant species were collected and analysed for chemical composition. The experimental animals 20 each of Thalli sheep and Teddy goats, located at Livestock Experiment Station Rakh Kharewala district Layyah (Pakistan) were randomly drawn from the main flock. The grazing pattern data were collected from one animal of each species. The observations regarding the grazing behaviour, breeding efficiency and carcass quality were also determined. It was found that overall preference index of Teddy goats were higher for Khabble (Cynodon dactylon) indicated by percent of the total number of bites made on different plant species, while the bites on Lumb (Aristida plumose), Mahabbat booti (Cenchrus biflorus), Dhaman (Cenchrus ciliaris) and Karera (Elionorus hirsutus) were found to be 1.28, 6.74, 0.32 and 3.87 percents. The browsing species as a whole were utilized more during the draught period. Among the grasses, sheep heavily utilized Khabble grass, with overall bite percentage of 89.27. Within browsing species Wan (Salvadora oleoides) and wind fallen dry leaves of Wan were considerably picked by the sheep showing 1.19 and 3.49 overall bite percentage respectively. The overall daily growth rates & dressing percentage for Teddy goats and Thalli sheep were 48.33, 39.00 and 51.00, 46.00 percent respectively. Moreover, among the experimental animals 50 percent goats exhibited signs of oestrus where as none of the sheep came into heat during the study period.

Web-based information services should be evaluated for accessibility and usability with various types of Internet Web-browsing devices, interacting with web information servers. A reliable ubiquitous Web information server, accessible and usable with a variety of Web-browsing devices (e.g. a full-browsing mobile phone), should be a unified center for personalized ubiquitous Web information services as well as for business models based on personalized advertisements. We studied an estimation of the accessibility and usability in Web interaction for personalized ubiquitous Web information services, as metrics for real-time estimation. We show empirical results based on implementation and experiments in Korea, Japan and China, using a test-bed Web site ('ktrip.net') and single-character Korean domain names (e.g. 김.net, 이.net, 박.net, 최.net, ㄱ.net, ㄴ.net ... ㅎ.net, ㅏ.net, ... ㅔ.net, ㄱ.com, ㄴ.com ... ㅎ.com).

The purpose of this study was to design and evaluate a metadata system for internet-based syllabi in computer science. The study constructed two prototype systems for the experiment. One was constructed using only Dubline Core (DC) elements and the other was a DC-expanded system with additional eight elements that are not the part of DC elements. The thlrty subjects were chosen from those who majored in Computer Science. Two retrieval tasks were assigned to them. One was to find syllabi in which they are' interested and the other was to find relevant course syllabi for a given course title. After the search, they were asked to evaluate the systems in terms of efficiency, accuracy, and their satisfaction of the system. The result of the first experiment indicates that DC-based system performed significantly better in terms of search time and DC-expanded system in terms of satisfaction measure. An additional experiment was conducted to test efficiency of the browsing categories. The interview with subjects was carried out to find any difficulties associated with the current browsing scheme. The subjects expressed much1 satisfaction about assigning a course to multiple browsing categories.

One of the main purpose of multiple-view image processing technology is support realistic 3D image to device user by using multiple viewpoint display devices and compressed data restoration devices. This paper proposes a multiple view image synthesis scheme based on RAM disk which makes possible to browse 3D images generated by applying effective composing method to real time input stereo images. The proposed scheme first converts input images to binary image. We applies edge detection algorithm such as Sobel algorithm and Prewiit algorithm to find edges used to evaluate disparities from images of 4 multi-cameras. In addition, we make use of time interval between hardware trigger and software trigger to solve the synchronization problem which has stated ambiguously in related studies. We use a unique identifier on each snapshot of images for distributed environment. With respect of performance results, the proposed scheme takes 0.67 sec in each binary array. to transfer entire images which contains left and right side with disparity information for high quality 3D image browsing. We conclude that the proposed scheme is suitable for real time 3D applications.

This study examines the design and utilization of video storyboard surrogates in the digital video libraries. To do this, first we constructed the arrangement model of key-frames for storyboard based on the FRBR model, image communication and PRECIS Indexing theories and evaluated the model using 6 sample videos and 26 participants. The study results show that the video storyboard surrogates based on the arrangement model has a higher accuracy value in terms of summary extraction than that of the sequential video storyboard. Moreover, watching both types of video storyboard one after another, especially browsing the sequential video storyboard first and then the arrangement model-based one, produces a remarkable increase in accuracy value of summary extraction. The study proposes two methods of utilizing the video storyboard surrogates in the digital video libraries: Designing a video browsing interface where users can use the sequential storyboard as a default and then the arrangement model-based one for re-watching; and utilizing the arrangement model-based storyboard as structured match sources of image-based queries.
