This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e-marketplace, but also can be applicable to both public and private types of e-marketplaces. This solution is different from the most of the public e-marketplace solutions that their main sources of revenue are transaction commissions or transaction fees through the third-party intermediation. Instead, this solution provides an ASP (Application Service Provider) functionality for direct, disintermediated purchasing and sales-related transactions between suppliers and buyers. With this functionality, suppliers and buyers electronically commerce with each other without the disclosure of their transactions as well as transaction commissions.

In the large scale B2B transaction like buying ´Express-Train´ or selling ´Daewoo Motor`, a tremendous amount of variables and factors of chaos functionate in it directly or indirectly. To get the effective information processing on the so called complex system like this, it should be possible to unite the human´s ability on the implicit information processing and the agent´s ability on the explicit information processing. In this paper, we suggested a union model for uniting these two heterogeneous abilities and showed how the suggested model can be used for processing the information of such a complex system as B2B negotiation.

Glass films in the binary system B2O3-SiO2 and Al2O3-SiO2 were prepared on soda-lime-silica slide glass by the dip-coating technique from TEOS and boric acid or aluminum nitrate. Thickness of the films varying with viscosity and withdrawal speed were measured and effect of composition and firing temperature on the properties such as transmittance and refractive index were investigated. nM2O3.(100-n)SiO2(M=B or Al) films containing up to 20mol% B2O3 and 40mol% Al2O3 were transparent. Maximum transmittance at visible range were obtained for the sample containing 15mol% Ba2O3 and 32.5mol% Al2O3 and heat-treated at 50$0^{\circ}C$, respectively. Refractive index of the film containing 15mol% B2O3 was mininum in the B2O3-SiO2 binary system and minimal refractive index was appeared at the film containing 32.5mol% Al2O3. In IP spectra, addition of B2O3 were increased absorption peak intensity of B-O and Si-O-B bond and addition of Al2O3 were decreased absorption peak intensity of Si-O bond, respectively.

At present, the electronic catalog format and the process system which are used in B2B (Business-To-Business) electronic commerce are applying different system architectures according to their businesses and industries characteristics. B2B business corporations using the electronic commerce started to consider the importance of standard electronic catalog format to enhance their interoperability. As a result, the necessity of unified electronic catalog system gathered strength in exchanging and managing enormous information of electronic catalog process system constructed in each corporation and industry. Therefore, we suggest data format to improve interoperability using XML (eXtensible Markup Language), as a standard document format in electronic catalog document and define the structure of electronic catalog document in processing the information of goods using XML Schema. In addition, we presents the integrated electronic catalog registry system which provides the service of searching and registering using the electronic catalog document defined through XML for each corporation to use it in electronic marketplace. Furthermore, we exhibits a model of the electronic catalog document that improves its interoperability and reusability in electronic commerce and a model of integrated electronic catalog system.

E-commerce requires many different types of communications and an unprecedented amount of data changes hands. The many different Platforms and systems interacting require a platform neutral standard for data exchange. One of the technologies that can fill this niche is XML, the extensible markup language established as a standard by the W3C. By being standardized and platform neutral, XML to be factor in e-commerce application and using many systems In this paper, we designed XML document that is used in transaction between corporations, and implement the B2B integration system based on XML database system. Also we use XSLT that make efficient transformation XML documents for exchanging heterogeneous XML data between corporations. So, he or she can more easily and efficiently exchange XML documents between corporations using this system.

Although thymomas are relatively common mediastinal tumors, to date not only has a universal system of pathologic classification not been established but neither has a clearly defined predictable relationship between treatment and prognosis been made. Recently, a new guideline for classification was reported by WHO, and efforts, based on this work, have been made to better define the relationship between treatment and pro­gnostic outcome. In the present study a comparative analysis between the WHO classification and Masaoka stage system with the clinical disease pattern was conducted. Material and Method: A total of 98 patients undergoing complete resection for mediastinal thymoma between Juanuary 1993 and June 2003 were included in the present study. The male female ratio was 48 : 50 and the mean age at operation was $49.6{\pm}13.9\;years.$ A retrospective analytic comparison studying the relationship between the WHO classification and the Masaoka stage system with the clinical disease pattern of thymoma was conducted. Pathologic slide specimens were carefully examined, details of postoperative treatment were documented, and a relationship with the prognostic outcome and recurrence was studied. Result: There were 7 patients in type A according to the WHO system of classification, 14 in AB, 28 in B 1, 23 in B2, 18 in B3, and 9 in type C. The study of the relationship between the Masaoka stage and WHO classification system showed 4 patients to be in WHO system type A, 7 in type AB, 22 in B 1, 17 in B2, and 3 in type B3 among 53 $(54{\%})$ patients shown to be in Masaoka stage I. Among 28 $(28.5{\%})$ patients in Masaoka stage II system, there were 2 patients in type A, 7 in AB, 4 in B 1, 2 in B2, 8 in B3, and 5 in type C. Among 15 $(15.3{\%})$ in Masaoka stage III, there were 1 patient in type B1, 3 in B2, 7 in B3, and 4 in type C. Finally, among 2 $(2{\%})$ patients found to be in Masaoka stage IV there was 1 patient in type B1, and 1 in type B2. The mean follow up duration was $28{\pm}6.8$ months. There were 3 deaths in the entire series of which 2 were in type B2 (Masaoka stages III and IV), and 1 was in type C (Masaoka stage II). Of the patients that experienced relapse, 6 patients remain alive of which 2 were in type B2 (Masaoka III), 2 in type B3 (Masaoka I and III) and 2 in type C (Masaoka stage II). The 5 year survival rate by the Kaplan-Meier method was $90{\%}$ for those in type B2 WHO classification system, $87.5{\%}$ for type C. The 5 year freedom from recurrence rate was $80.7{\%}$ for those in WHO type B2, $81.6{\%}$ for those in type B3, and $50{\%}$ for those in type C. By the Log-Rank method, a statistically significant correlation between survival and recurrence was found with the WHO system of classification (p<0.05). An analysis of the relationship between the WHO classification and Masaoka stage system using the Spearman correction method, showed a slope=0.401 (p=0.023), showing a close correlation. Conclusion: As type C of the WHO classification system is associated with a high postoperative mortality and recurrence rate, aggressive treatment postoperatively and meticulous follow up are warranted. The WHO classification and Masaoka stage system were found to have a close relationship with each other and either the WHO classification method or the Masaoka stage system may be used as a predict prognostic outcome of Thymoma.
