The problem of choosing the right product that will best fit a consumer's taste and preferences extends to the field of electronic commerce. However, e-commerce has been able to create a technological proxy for the social filtering process, known as online recommender systems (RSs). RSs aid users in filtering products and decisions on matters relating to personal taste. RSs have the potential to support and improve the quality of the decisions consumers make when searching for and selecting products and services online. However, most previous research on RSs has focused on the accuracy of the algorithms, with little emphasis on user interface and perspectives. This study identified transparency and feedback as possible ways to effectively evaluate RSs from the user's perspective. Thus, this research focused on examining and identifying the roles of transparency and feedback in recommender systems and how they affect users' attitudes toward the system. Results of the study showed that both transparency and feedback positively and significantly affected perceived trust, perceived value of the process, and perceived enjoyment. Furthermore, we found that perceived trust, perceived value of the process, and perceived enjoyment positively and directly affected users' intentions to use/reuse a recommender system.

The electronic stores have realized that they need to understand their customers and to quickly response their wants and needs. To be successful in increasingly competitive Internet marketplace, recommender systems are adapting data mining techniques. One of most successful recommender technologies is collaborative filtering (CF) algorithm which recommends products to a target customer based on the information of other customers and employ statistical techniques to find a set of customers known as neighbors. However, the application of the systems, however, is not very suitable for seasonal products which are sensitive to time or season such as refrigerator or seasonal clothes. In this paper, we propose a new adjusted item-based recommendation generation algorithms called the exponentially weighted collaborative filtering recommendation (EWCFR) one that computes item-item similarities regarding seasonal products. Finally, we suggest the recommendation system with relatively high quality computing time on main memory database (MMDB) in XML since the collaborative filtering systems are needed that can quickly produce high quality recommendations with very large-scale problems.

The purpose of this thesis is to analyze the present conditions and problems of the Internet Fashion Shopping-Mall, grope for as active plan to the Internet Fashion Shopping-Mall as a strategic method of fashion industry. The fashion industry of Internet Electronic Commerce has good prospect, and I propose the following some strategic plans of Internet Fashion Shopping-Mall. On the basis of my study, as a means of technology supplement, Virtual Reality System, such as 3D System or the newest Electronic Dressing Room System to solve the problem of products'an actual feeling, should be needed for consumers to feel as they really put the clothes on. Second, to offer more diversity programs, such as consumer sensitivity program, additional service, fashion news, life information and so on, are needed for companies to come over again the consumers to connect to the shopping-mall site. And, to build more perfect security terms of payment systems, such as ICash, Disital Cash, Net Check, Internet Insurance and so on, should be introduced for consumers to pay and furnish their personal information. If these technological developments are realized, Internet Fashion Shopping-Mall products will be a great success.

A service broker supporting customers plays an important role in internet marketplaces. Recently. several intelligent brothers have been developed for electronic commerce, outline shopping mall, and electronic marketplaces. While these systems provide interesting shopping experiences, they fall short in fully exploiting the capabilities, such as the service integration and automatic execution required by internet market places. In this respect, we propose a workflow-based service broker system. Dependent services in our approach are modeled as workflow processes, which are automatical1y processed by a workflow engine. In the proposed system all data exchanges are realized through XML providing platform independent, extensible, open. and interoperable architecture.

Globally, Fintech, which acts to replace existing intranational payment methods, is actively used, and such Fintech payments are widely accepted in international B2C trade. However, Fintech for B2B trade has not been released to the market thus far, and previous attempts at electronic international payment systems, such as Bolero, TradeCard, and Identrus, have not succeeded, and most of them have completely disappeared. On the other hand, there are continuing attempts to introduce Fintech technologies such as blockchain to international payments, and these attempts are more widely pursued in foreign countries. If international payments using Fintech are marketed through foreign services and such Fintech services become the de-facto standard for international payments, then Korea in which dependency on international trade is high will be vulnerable due to a dependency on foreign services such as relying on foreign SNS platforms like Facebook and Instagram. Therefore, this paper proposes a business model that can be used as a legitimate B2B trade international payment system on the basis of domestically provided services, focusing on various services afforded by K-SURE, which is the Korea Trade Insurance Corporation.

미국과 유럽에서 추진되고 있는 ITS(Intelligent Transport Systems : 고도도로교통시스템) 도로통신에서 취급하는 정보의 정의, 통신방식의 표준화 등의 동향에 대한 개요를 기술한다. 미국에서는 NTCIP(National Transportation Communication for ITS Protocol)라 불리우는 통신프로토콜, 데이터 딕셔너리, 메시지 셋트 등의 표준화가, 유럽에서는 DATEX-Net라는 데이터 교환의 표준화가 추진되고 있다. 이들은 ITS 분야에서의 시스템 간 및 장치간의 상호운용성$\cdot$호환성을 확보하고 통합적으로 ITS를 전개해가기 위한 기반정비의 주요 항목이다. 양자 공히 표준적인 통신프로토콜이 채용되고 있으나 정보내용, 메시지포맷에 대하여는 NTCIP가 ASN.1(Abstract Systax Notation 1)에서 기술한 MIB(Management Information Base)구조를 갖고 있는 한편, Datex-NET는 독자적인 구조의 사전과 EDIFACT(Electronic Data Interchange for Administration Commerce and Transport)에 따른 메시지사양으로 되어 있어 공통성이 없다. 그러나 센터간 통신에 관하여는 미국에서 제안한 DATEX-ASN이라는 표준화 안에 대하여 유럽에서 전향적인 평가를 하고 있어 통일화의 징조가 보이고 있다.

Web information systems have been utilized extensively over the past decade. The Internet allows for the entire sales cycle to be conducted on one medium, nearly instantaneously. From making the consumer aware of the product to providing additional information to transacting the final purchase, the Internet can accomplish them all. The Internet is like one big point-of-sales display, with easy access to products and the ability for impulse shopping. Here, we point out different aspects of information technology (IT) in marketing. Consequently, we propose two frameworks as decision aids in web-based marketing environment.

Traditional intermediaries refer to service providers such as travel agents, real estate brokers, job agencies and insurance agents which matching services for buyers and suppliers in a traditional market. The introduction of Electronic commerce resulted in the automation of many tasks provided by intermediaries and seemed to eliminate the role of many traditional intermediaries, which is called disintermediation. However, depending on their market power, traditional intermediaries either will be disintermediated or fill new roles by providing added value and assistance, which is called reintermediation. According to the research of Alina M. Chircu et al. there are three conditions for reintermediation for traditional intermediaries. Three conditions are weak appropriability of EC innovations, ownership of co-specialized assets for both market intermediation and EC innovations and economies of scale. Besides these three reintermediation conditions, we hypothesize that leveraging BPO can be a suitable strategy for traditional intermediaries to be transformed into reintermediaries. Business Process Outsourcing (BPO) is the leveraging of technology or specialist process vendors to provide and manage an organization's critical and/or non-critical enterprise processes and applications. This paper will investigate the relationship between above reintermediation conditions including BPO and reintermediation.
