Korea-China with the fastest speed Internet Broad Band, has achieved many progresses on Internet shopping. Especially, Korea has made a great effort on comparison website construction. A research prototype design and exploratory analysis are presented to assess success factors and impacts of Korea and China price comparison websites. For different user groups, the relationships between the characteristics of technology and tasks, usage, and organizational impacts were analysed. It shows us how to improve the applicability of fit-viability of the price comparison web sites in China after analysis. These results indicate a need for simple but highly functional price comparison applications. And we designed a sample model to include an interactive web service system for price comparison sites that complement existing information systems. This paper provides a basis for further research aiming to improve the design and management of business applications based on emerging technologies of web service and browser for information management.

This paper empirically analyzed consumer price search behavior using Web log data of a Korean web site for price comparison. Consumer click-stream data of the site was used to test the effects of price level, product category, third party certification, reputation of retailers on click behavior. According to the descriptive statistics, 67.4% of shopbot users clicked the offer which was the lowest price returned in a search. We found that third party certification and reputation of retailers were significant determinants of clicking the lowest priced offer from legit analysis. We also applied Tobit regression analysis to estimate the price premium of the two determinants, but only reputation of retailers was found to have price premium of 4.9%.

The purpose of this study was to identify the criteria of evaluating a price-comparison website, and to investigate the consumers' perceived importance and satisfaction of each criterion. Also, it compared both the importance and satisfaction levels based on consumers' socio-economic and Internet-usage characteristics. Data for this study came from a questionnaire completed by consumers (n=417), who had used the price-comparison website, and were analyzed through factor analysis, t-test, and ANOVA. The findings of the study were as follows: First, the evaluation criteria of the price-comparison website were categorized into five variety of information, accuracy, convenience, credibility, and the website system. Second, convenience of searching information was seen by consumers as both the most important and most satisfactory criterion. Variety of information was also considered important. For most of the evaluation criteria, the level of consumers' satisfaction was significantly lower than the level of consumers' recognized importance. Third, consumers in their 20s, students, and housewives were less likely to be satisfied by the price-comparison website overall. Older people were less likely to be satisfied with the convenience of the website, and the higher-income group was less likely to be satisfied with the variety of information on hand.

Currently, as the public interest for environmental issues has grown rapidly, the needs for G-SEED have also increased. However, as investment according to eco-friendly elements is inevitable to receive G-SEED certification, it is necessary to find out whether or not the sales price of apartments have increased compared to investment costs. Therefore, the objective of this study is to analyze the sales price of apartments according to G-SEED by using T-test. To achieve the objective, First, variables affecting on the sales price of apartments are selected. Second, the data are collected by using GIS(Geographic Information System). Third, after testing the normality, a comparison analysis is conducted on the sales price between G-SEED certified and non-certified apartments by using T-test. As a result, it is concluded that G-SEED certified apartments are more expensive than non-certified apartments. In the future, these findings can be utilized to develop of apartments price calculation model based on the G-SEED.

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.

There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping malls in synchronous. So If they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS (Java Message Service) that is a standard Java API for MOM (Message-Oriented Middleware).

I have observed the validity of open-offer from a point of European contract law in comparison with International Trade Law in this paper. Generally we know that an offer is an expression of willingness bo be bound to the contract. In English law if there are no intention it will be considered such as circulation of price lists or catalogues. As for French law these activities could be considered as an offer. However German law is closer to English law as to an offer. A contract which does not ascertained price is open-price terms and it can be applied not only for general commercial contracts but also for franchise or for distributorship agreements especially in Europe. When open-price terms applied to reserve a exclusive right to the contract the validity of contract can be a serious matter between principals. In English law an offer must be sufficiently complete to be capable of acceptaqnce. English law does not require that price terms should be indicated on offer. English law allow a open-price terms in the contract. In French law a contract will be valid in the absense of a price which is either determined or objectively determinable. A price by the market price of similar products is not enough to be valid offer. It should be recognized and accepted objectively by third parties. French law require that price terms should be indicated on offer. Open-price terms are not enough to be an effective offer. However German law shows more flexible than French law. In German law if the price is not fixed in the contract there are four ways to determine it. The seller may determine the price by the time of deliver. By reason of thess backgrounds I have made comparison with European contract law and International trade law on the validity of open-price offer in this paper. It seems that we are not familiar with open-price terms although franchise contract or special terms of contract have been increased in these days. So I hope this paper will be helpful to show a new point of view.

This study examines the effects of restaurant attributes on customers' perceptions of price and brand reputation. Four restaurant attributes were used to represent restaurant quality. Multiple regression was conducted to measure the relationships between the four restaurant attributes and price and brand reputation. Further, an independent T-test was used to compare differences between perceptions of locals and tourists with regard to restaurant quality under two categories (price and brand reputation) after they selected a restaurant. Results of this study revealed that residency did not have a significant impact on customers' perceptions of price or brand reputation, whereas restaurant attributes did have an impact. Taste was a predictor of perceived price, whereas service and atmosphere were predictors of brand reputation. In addition, comparison of restaurant attributes between locals and tourists showed that sanitation and service were significantly different in accordance with price and atmosphere, whereas taste and service were significantly different in accordance with brand reputation. Locals showed higher means for each restaurant attribute compared to tourists.

Currently, Price comparison sites receive inputs of product information and price manually after being joined by releted shopping mall companies, and can't support automatically price fluctuation of products in real time. Therefore, this paper designs and implements web service system based on SOAP for interactive product order and price comparison dynamically using web service technologies in real time. This web service system composes web service client module including functions of product search, sort and order, and server module including functions of remote procedure call for product search and order. This web service system implements interchanging product information based on SOAP messages and can support independence of platform and flexible potability in environment conforming to SOAP, WSDL and UDDI standards.
