It is well known that internet shoppers are very sensitive to sale prices. They visit the various shopping malls and collect the product information including purchase conditions for goods purchase decision-making. Recently the necessity of information support is increasing because of increase of information amount which is necessary and complexity of goods purchase decision-making process. The comparison shopping agent systems have provided price comparison information which is collected from various shopping malls to satisfy internet shoppers information craving. But the frequent price change caused by keen price competition is becoming the primary reason of information quality decline among price comparison sites. RSS which is a family of web feed formats used to publish frequently updated is applied even in on-line shopping malls. This paper develops a RSS product information collection system to get real-time product information. The proposed product information system consists of (1) web crawler module for searching RSS feed shopping malls automatically, (2) RSS reader module for parsing product information from RSS feed file, (3) product DB and (4) product searching module. Performance of the proposed system is higher than the comparison shopping agent systems when it is defined with the volume of collecting product information per unit time.

The purpose of this article was to research the difference in additional marketing satisfaction by lifestyle of Korean restaurant customers (focus on foreign students at university in Gangwon province). In this research, factor analysis, cluster analysis, and ANOVA were carried out. Lifestyle was divided into seven factors and six clusters. Additional marketing satisfaction was divided into three factors. Additional marketing satisfaction showed a significant difference by lifestyle of foreign students. First, 'employee' had a highest point at C3 'convenience internet searching pursuit' but lowest point at C4 'brand preference pursuit' (p<0.001). 'Service process' had a highest point at C1 'safety health pursuit' but lowest point at C5 'effort pursuit' (p<0.001). 'Tangible clue' had a highest point at C3 'convenience internet searching pursuit' but lowest point at C5 'effort pursuit' (p<0.001). Additional marketing can reduce customer uncertainty, ambiguities, and wavering about eating at restaurants by intangibility of service. As a result, food-service corporations need to manage additional marketing as well as increase satisfaction and loyalty of customers.

Recently, introduction of the hospital information system has remarkably improved the efficiency of health care services within hospitals. Due to improvement of the hospital information system, the issue of integration of medical information has emerged, and attempts to achieve it have been made. However, as a preceding step for integration of medical information, the problem of searching the same patient should be solved first, and studies on patient identification algorithm are required. As a typical case, similarity can be calculated through MPI (Master Patient Index) module, by comparing various fields such as patient's basic information and treatment information, etc. but it has many problems including the language system not suitable to Korean, estimation of an optimal weight by field, etc. This paper proposes a method searching the same patient using MRI information besides patient's field information as a supplementary method to increase the accuracy of matching algorithm such as MPI, etc. Unlike existing methods only using image information, upon identifying a patient, a highest weight was given to physical information of medical image and set as an unchangeable unique value, and as a result a high accuracy was detected. We aim to use the similarity measurement result as secondary measures in identifying a patient in the future.

Objectives : On the internet, the bibliographic information service systems of the theses for the degree of Korean medicine(KMT) have been builded by the National assembly library, the National library of Korea and the eleven central libraries of eleven colleges of Korean medicine in Korea(KMU). Because there was a lot of information of Korean medicinal research & development(R&D) in those KMT, the MKT are most valuable in the Korean medicinal R&D. This study was carried out to understand and analyze the information service systems of the theses of Korean medicine provided by those libraries. Methods : We collected the bibliographic information of KMT on the internet in the National assembly library, the National Library of Korea, KMU, and some references of KMT, and then made a comparison between the bibliographic information of KMT and those KMU about the simpleness of searching and the accuracy of the contents. Results : Many of the Korean medicinal information service systems of KMU are poor on the simpleness of searching and the accuracy of the contents. On the accuracy of the contents, the bibliographic information service systems of KMT mistakes about 20% because of misusing of a Chinese character, a rule of the initial sound of a syllable of the Korean alphabet, and an erroro of the term day on KMT.

Focusing on the issue that the conventional Kernel Correlation Filter (KCF) algorithm has poor performance in handling scale change and obscured objects, this paper proposes an anti-occlusion and scale adaptive tracking algorithm in the basis of KCF. The average Peak-to Correlation Energy and the peak value of correlation filtering response are used as the confidence indexes to determine whether the target is obscured. In the case of non-occlusion, we modify the searching scheme of the KCF. Instead of searching for a target with a fixed sample size, we search for the target area with multiple scales and then resize it into the sample size to compare with the learnt model. The scale factor with the maximum filter response is the best target scaling and is updated as the optimal scale for the following tracking. Once occlusion is detected, the model updating and scale updating are stopped. Experiments have been conducted on the OTB benchmark video sequences for compassion with other state-of-the-art tracking methods. The results demonstrate the proposed method can effectively improve the tracking success rate and the accuracy in the cases of scale change and occlusion, and meanwhile ensure a real-time performance.

Since frequent item extraction so far requires searching for patterns and traversal for the FP-Tree, it is more likely to store the mining data in a tree and thus CPU time is required for its searching. In order to overcome these drawbacks, in this paper, we provide each item with its location identification of transaction data without relying on conditional FP-Tree and convert transaction data into 2-dimensional position information look-up table, resulting in the facilitation of time and spatial accessibility. We propose an algorithm that considers the mapping scheme between the location of items and items that guarantees the linear time complexity. Experimental results show that the proposed method can reduce many execution time and memory usage based on the data set obtained from the FIMI repository website.
