The purpose of this research is to evaluate the degree of transactions of the electronic commerce in the hospitals. We created well-organized questionnaire to achieve this goal. we did telephone interviews with the hospitals, and then we reached out to the hospitals by e-mail and postal mail. We interviewed 311 hospitals, and 104 hospitals participated in this study. We conducted cross tabulations. The results are following : Among the subjects, male was 77.9%(81) and female was 22.1%(23). 51.0% of the hospitals used electronic commerce in their work purpose. The proportion of the hospitals that started their electronic commerce before 2000 years was 30.2% and after 2000 years was 69.8%. In the major electronic commerce service providers, 30.4% of the hospitals had their contract with auction, 18.4% of the hospitals had their contract with public procurement services. which is running by Korean government, and 11.8% were with EZmedicom and 10.8% were working with Carecamp. Through electronic commerce, the most high usage was office supplies 41.0% and the send area was medical supplies 11.2%. The results of this study suggest that electronic commerce in health care field is a very new area compared to other industries. There may be lots of barriers in the aspects of a way of working and norms of health care field. Electronic commerce system and contracts with their electronic commerce service providing partners.

The evolution of blockchain-based systems has enabled researchers to develop nextgeneration e-voting systems. However, the classical consensus method of blockchain, that is, Proof-of-Work, as implemented in Bitcoin, has a significant impact on energy consumption and compromises the scalability, efficiency, and latency of the system. In this paper, we propose a hybrid consensus model (PSC-Bchain) composed of Proof of Credibility and Proof of Stake that work mutually to address the aforementioned problems to secure e-voting systems. Smart contracts are used to provide a trustworthy public bulletin board and a secure computing environment to ensure the accuracy of the ballot outcome. We combine a sharding mechanism with the PSC-Bchain hybrid approach to emphasize security, thus enhancing the scalability and performance of the blockchain-based e-voting system. Furthermore, we compare and discuss the execution of attacks on the classical blockchain and our proposed hybrid blockchain, and analyze the security. Our experiments yielded new observations on the overall security, performance, and scalability of blockchain-based e-voting systems.

The purpose of this paper is to make research on the method of arbitration agreement, the adoption and contents of the Convention on the Use of Electronic Communications in International Contracts, and the standpoint and problem with reference to the new Convention's application to the method of arbitration agreement in New York Convention. Last year the UN General Assembly and UNCITRAL adopted a new Convention on the Use of Electronic Communications in International Contracts that makes agreements by electronic communications enforceable, including arbitration agreements under the Convention on the Recognition and Enforcement of Foreign Arbitral A wards (New York Convention). Aimed at enhancing legal certainty and commercial predictability where electronic communications are used in relation to international contracts, the provisions of the Convention deal with, among other things, determining a party's location in an electronic environment; the time and place of dispatch and receipt of electronic communications; and the use of automated message systems for contract formation. Under the New York Convention, arbitration agreements in international contracts must be reduced to writing before they can be enforced. But under the new Convention, an arbitration agreement made entirely in electronic form would be enforceable. The working group expressed overall support in favor of the inclusion of a reference to the New York Convention in the new Convention. However, one proposal was that the exclusions provided under article 2 of the new Convention might be too broadly worded to adequately accommodate the New York Convention. In conclusion, Korea's government authorities should take prompt measures to sign and ratify the new Convention, and declare on the scope of its application. Also Korea's arbitration institute should make preparation for the amendment of the arbitration act and arbitration rules in accordance with the new Convention.

The purpose of this study aims to analyse the key differences of the sea waybill and electronic B/L in the international transport documents. Sea waybills look remarkably like ordinary bills of lading. Indeed, in two important ways, they are just like bills of lading: the front of the document will near a description of the quantity and apparent condition of the goods; and the back of the document provides evidence of the terms of the contract of carriage. They differ from bills of lading in that, far from indicating that the goods described are deliverable to the order of the shipper or of the consignee, they will make it explicit that the goods are deliverable only to the consignee. Again, different carries will do thai in a variety of ways. For example, the document may call itself non-negotiable, omitting the word order from the consignee box on the front of the document, and stating explicitly that the goods will be deliverable to the consignee or his authorised representative on proper proof of identity and authorisation. The Hague-Visby Rules and Hamburg Rules give no guidance as to any right to instruct the carrier in respect of goods while they are in transit. However, in applying Article 50 of the Rotterdam Rules, in particular when applying it in the context of seawaybills, straight bills of lading or ship's delivery orders, regard would need to be had to preserve the shipper's rights under any of those three documents even after the buyer of goods covered by them has acquired rights of its own. And, the right of control is defined at Article 1.12 of the Rotterdam Rules. The right to give instruction is further limited by the terms of Article 50.1 to three particular types of instruction in respect of the goods, relating broadly to the goods, their delivery en route, and the identity of the consignee. And, the CMI formulated the CMI Uniform Rules for Sea Waybills for voluntary incorporation into any contract of carriage covered by such a document. Recognising that neither the Hague nor the Hague-Visby Rules are applicable to sea waybills, the CMI Rules provide that a contract of carriage covered by a waybill shall be governed by whichever international or national law, if any, would have been compulsorily applicable if the contract had in fact been covered by a bill of lading or similar document of title.

In this digital environment, license contracting and technical protection measure are being used by copyright holders as a means to restrict the rights of information users. The study reviewed the conflicting relationship between the copyright law and the contract law for digital resources the use of which is based on license contracting, and investigated the legal interpretations of the conflicting relationship between the two. And then based on the analysis of IF LA's position on copyright in the digital environment, the study suggested the expected role of librarians to cope with the technological overrides of copyright rules and to expand the rights of information users.

A combination of information technology and medical care has given rise to a new type of medicine, i.e., telemedicine. Broadly defined, telemedicine is the transfer of electronic medical data from one location to another. Both at home and abroad, telemedicine has come to success in establishing appropriate equipment and solutions for such non-conventional medicine. Sooner or later, telemedicine is believed to find itself as one of the universal treatments. In order to facilitate the full-fledged development of telemedicine, a number of legal and institutional problems have to be settled. In Korea, the Medical Act was amended to include such provisions as telemedicine, electronic medical records, electronic prescriptions, etc. and the Act came into force on March 31, 2002. Telemedicine is in common with the conventional medicine in that a physician treats a patient. However, telemedicine is basically differentiated in the followings: - The offer and acceptance of treatment and medication are usually made on-line; - Telemedicine is inherently dangerous because a physician cannot meet face-to-face with a patient; and - Joint and several liability is borne by all the physicians involved in a telemedical consultation. As a result, telemedicine is vulnerable in nature to medical malpractice. Accordingly, there must be some new theories and arguments in the formation of contract and torts. The discussion on the civil liability covers the above-mentioned issues, and would give an insight or guidelines in the concerted operation of provisions with respect to telemedicine. This study delves into the civil liability of physicians involved in telemedical consultations and treatments based upon the conventional malpractice theory.

This study is focused on the problems and the suggestions of proper ideas for solving them which are arisen from appling CIF, Incoterms 1990 into the contract of sale after reviewing of the contents of traditional CIF contract and the main changes of CIF, Incoterms 1990. This study summerized as follows: First, when the seller provide the buyer with non-negotiable sea waybill or inland waterway document instead of negotiable bill of lading, it is my feeling that the essence of symbolic delivery in traditional CIF contract is fading. And if the buyer has paid for the goods in advance, or a bank wishes to use the goods as security for a loan extended to the buyer, it is not sufficient that the buyer or the bank be named as consignee in a non-negotiable document. This is true because the seller by new instractions to the carrier could replace the named consignee with someone else. To protect the buyer or the bank it is therefore necessary that the original instructions from the seller to the carrier to deliver the goods to the named consignee be irrevocable. Second, CIF term can only be used for sea and inland waterway transport. When the ship's rail serves no practical purposes such as in the case of roll-on/roll-off or container traffic, CIP term instead of CIF term is more appropriate to use. Third, the EDI method still contains many legal and technical problems to be solved in order to be used thoroughly' in the international sale of goods. Therefore, the parties wishing to replace the traditional paper-based trade documents by electronic messages must exchange the agreement on EDI each other in order to prevent and sol ye unexpected problems. Forth, it may be that the goods are to be carried in bulk without such marking or naming of consignee as would amount to appropriation. Then the risk will not pass until effective appropriation has been made. Therefore, the seller needs to appropriate by issuing of separate bills of lading or delivery orders for parts of the bulk cargo. And in case the goods are bought while they are carried at sea, some problems on the passing of risk would arise. One possibility is that the buyer might have to assume risks which have already occured at the time when the contract of sale is entered into force. The other possibility would be to let the pissing of the risk concide with the time when the contract of sale is concluded. The parties are advised to ascertain the applicable law and any solution which might follow there form. Finally, Incoterms are restricted to deal with the main principles for the division of functions, costs and risks between the parties and the rest is left to their individual contract as supplemented by the custom of the trade, the individual terms of the contract of sale and the applicable law. Thus, the parties are advised to ascertain the applicable law on their individual contract of sale in order to solve the problems on the transfer of property, the remedy and so on.

The purpose of this paper is to analysis the legal aspects of e-commerce, particularly those relate to electronic contract, in China On 23 November 2005, the United Nations General Assembly adopted a Convention on the Use of Electronic Communications in International Contracts, known popularly as the Electronic Communications Convention. China signed it but the convention is not binding yet as it still requires the ratification by three states. On the other hand, China adopted a new act legalizing the electronic signature in 2004. This new act provides electronic signatures with the same legal status as handwritten signatures. But the efficiencies that business hopes to achieve through electronic commerce are not completely reflected in the legal processes necessary to support those hopes.

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).
