The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and sewer, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority (CA).

최근의 통상환경중 "Logistics" 혁명을 통한 컨테이너 운송의 신속화, 인터넷혁명을 통한 전자상거래 활성화는 EDI, EC등을 통해 "Paperless trade"가 실현을 앞당기고 있다. 본 논고는 이러한 물류혁명과 인터넷 정보기술의 발달로 대두되는 문제중 기존의 종이서류로서의 운송서류를 전자식 운송서류로 대체하는데 따른 문제점과 이의 활성화 방안에 대해서 살펴보고자 한다. 인터넷 전자거래가 활성화되어지면 기존의 종이서류들은 전자메시지로 대체될 것으로 여겨진다. 이에 따라 전자계약서, 전자송장, 전자보험증권, 전자선하증권 등이 출현할 것이지만 이중 무엇보다도 전자식 운송서류중 유통성 운송서류의 전자화는 그간 전자화의 핵심부문으로 여겨서 상당한 중요성을 두어왔다. 현재 이용되는 유통성 운송서류는 그간 선하증권의 지연도착문제와 이에 따른 추가 경비의 소요, 또한 선하증권 발급에 따른 부대경비의 과다소비, 종이서류로서의 선하증권의 위조에 따른 사기문제 등에 제기되어 졌고 이에 따라 선취화물보상장 등의 현실적 대안이 제시되었지만 이 또한 여러 문제점을 야기시켜왔다. 전자식 운송서류는 이러한 문제점을 다소 해소할 수 있는 방안으로 알려져 왔다. 전자거래가 활성활 될 미래에는 운송서류의 전자화는 필연적으로 대두되게 될 것이고, 이러한 전자화에 있어 해상운송장의 사용은 바람직한 모델로 여겨지고 있다. 그렇지만 전매가 잦은 산업에 있어 해상운송장은 자체의 유통성의 미비로 인해 그 사용에 문제점이 있고, 실제 상관행에서 많은 이점을 가진 선하증권의 발행 욕구를 충족시켜 줄 수 있어야 할 것이다. 본 논고에서는 전자식 운송서류의 활성화 방안으로 첫째, 전자식 운송서류에 관한 법률정비가 필요할 것으로 여겨지며 둘째, 유통성 전자식 운송서류에 있어 관리기관의 안정성이 확보되어야 할 것으로 여겨지며 셋째, UCP에서 전자식 운송서류에 관한 조항이 삽입되어져야 할것으로 여겨지며 넷째, 여러 측면에서 우위성을 지닌 전자무역거래의 활성화는 점차적으로 운송서류의 전자화를 활성화시키는데 반드시 필요한 명제로 등장할 것으로 여겨진다.

The purpose of this paper is to investigate the determinants of new product diffusion. We seek to document and explain systematic features of product diffusion. In this essay, we examine the well-documented empirical regularity that the speed of diffusion has accelerated during the twentieth century. The empirical results show that the main source of acceleration are faster declines in prices. Faster price declines make the product affordable to more consumers within a given period of time. Based on theories of intertemporal price discrimination and learning-by-doing, the association between the speed of adoption and the speed of price decline was explained. Faster price declines are attributed to several product characteristics as well as changes in income distribution. Above all, the introduction of consumer electronic products in more recent years can be regarded as the most important factor in accelerating price declines. Consumer electronic products are technologically different from non-electronic goods, in that semiconductors are important components. As the price of semiconductors has dropped rapidly, the falling production costs can be rapidly incorporated to the price of consumer electronic goods. Furthermore, most of the recently introduced consumer electronic products have network externalities, and many products with network externalities require complementary products. A complementary product becomes more readily or cheaply available as more people have the main product. One major difference between previous studies and this study is that the former focuses only on the factors that operate directly on the speed of adoption, while this study incorporated factors that work through price changes as well as the factors that work directly on the speed of adoption.

EDI (Electronic Data Interchange) has been widely utilized to support Business Activities since it has such advantages as fast transfer of information, less documentation work, efficient information exchange etc. Recently e-business environment has urged the traditional EDI system to be changed to ebXML framework. To apply the ebXML framework to a certain industry, it is required to implement Business Process (BP), Core Component (CC), Collaboration Protocol Profile (CPP), Collaboration Protocol Agreement (CPA), Messaging system etc. We have selected the port and logistics industry as a target domain to apply ebXML framework, since the EDI usage ratio of it is relatively higher than other industries. In this paper, we have analyzed the current status of EDI system and transaction processes in the port and logistics industry. We have defined the business process that will be registered in the registry/repository, the main component of ebXML framework, using UN/CEFACT modeling methodology. And Business Collaborations, Business Transactions, Business Document Flows, Choreography, Pattern, etc. are represented using UML according to UN/ CEFACT modeling methodology, to apply ebXML Framework to the port and logistics distribution industry. Also we have suggested the meta methodology for applying the ebXML framework to other industries.

EDI(Electronic Data Interchange) works by providing a collection of standard message formats and element dictionary in a simple way for businesses to exchange data via any electronic messaging service. Open-edi is electronic data interchange among autonomous parties using public standards and aiming towards interoperability over time, business sectors, information technology and data types. The number of Internet services using XML/EDI has grown rapidly since it is easily expansible and exchangeable. To use this service, the client does not have to install EDI S/W but only needs internet browser. Consequently, it became much easier and faster to handle the trading process in an office. eBusiness SML (extensible markup language) electronic data interchange. eXedi is the service that realizes B2B of XML/EDI. eXedi can be used easily in small and medium sized companies. Companies in any place can access to eXedi using the existing Internet connection. XML/EDI provides a standard framework to exchange different types of data -- for example, an invoice, healthcare claim, project status -- so that the information be it in a transaction, exchanged via an Application Program Interface (API), web automation, database portal, catalog, a workflow document or message can be searched, decoded, manipulated, and displayed consistently and correctly by first implementing EDI dictionaries and extending our vocabulary via on-line repositories to include our business language, rules and objects.

To prevent the spread of damage, initial reaction and emergency repair are important. But up to now they depend on some guidelines and man power owing to the lack of technical support. In this paper, we described the development process of several electronic documents and information management system of them to rapidly acquire and share damage information of the infrastructure. The damage information, which is acquired by the computer and smart phone, is transformed to the electronic documents and connected to data management system through the damage information acquisition network. These systems could readily be used for preparing a countermeasure of the disaster and disaster recovery.

This study is concerned with an assistive technology which reduces color blinds´s confusion when they access electronic documents including color objects in their computers. In this study, 1 restrict the assistive technology would apply to windows operating system, 256 color mode and implement to minimize color distortion which occurs in multi window environments because of color approximation process. As a basic palette, I use a 216 colors web safe palette which the Christine proposed as a standard for color blind, expand it to 256 colors to apply all computer displays using Microsoft Windows as its operating system and implement it as windows application. To test its effectiveness, I use a simulator for dichromats, as results of the test, the developed color vision deficiency correction S/W is effective to reduce the confusion. It is more effective to use the implemented S/W in both of design and client process for electronic documents.

Although the National Archives of Korea has been receiving transfer of standard electronic documents with a retention period of more than 30 years from the central administration since 2015, errors and inefficiencies persist. Despite this, however, there remain no studies that analyze or address these issues. This study aims to bridge this gap and found that most errors in the transfer process occur at the production stage. To address such, this study proposes a four-step solution. First, before electronic document approval, the text and attached files are checked for defects to prevent errors. Second, as soon as the signature is made, digital signatures are applied on a file-by-file basis to ensure integrity. Third, integrity verification and transfer inspection are automatically performed through digital signature investigation and defect check procedure during transfer and preservation. Fourth and last, the criteria of acquiring records and integrity guarantee technologies are properly applied in production stage with proper management and supervision.
