Electronic commerce has already existed for over 20 years. In sectors such as retail and automotive, electronic data interchange(EDI) for application-to-application interaction is being used regularly. For defence and heavy manufacturing, electronic commerce life-cycle management concepts have been developed that aim to integrate information across larger parts of the value chain, from design to maintenance, such as CALS(Computer Assisted Life-cycle Support or Computer Aided Logistics Support). Bolero's mission is to provide guaranteed and secure delivery, in electronic form, of trade documentation, globally, based on a binding legal environment and common procedures. Bolero will also provide a platform for provision of neutral cross-industry services.

The main issue relating to electronic bill of lading is to develop the system in which can transfer the title to the goods by electronically, and to support effect of electronic transfer of title by law. BBL, electronic bill of lading being operated by bolero, provides technical devices to that purpose, but current law is not recognize the effect of transfer of title by electronic communication because BBL is different from paper bill of lading naturally. For that reason Bolero has resolved the problem by Rulebook which is multilateral agreement contracted between users and BAL. The Rulebook provides solution, so called, 'attornment' and 'novation'. So, The purpose of this study is to help in understanding BBL through comparison and analysis about the legal background of transfer of title by BBL based on 'attornment' and 'novation' with transfer of bill of lading based on a endorsement and delivery.

Based upon the provision of limitation of copyrights, libraries may provide the document delivery service which supplies copies of journal articles and book chapters owned at other libraries by request of users. However, more proactive information service is required as more users want to use the digital delivery of documents published overseas. This study reviews copyright law of Korea and international conventions related to the document delivery service. It then examines foreign cases to see how overseas information centers clear copyrights. Finally this study suggests that copyright clearance methods be adopted to make a proactive information service. Through those methods, a new information service model may be planned, which meets various information needs while protecting copyright.

Considerable attention is given to drug delivery technology that efficiently delivers appropriate levels of drug molecules to diseased sites with significant therapeutic efficacy. Nanotechnology has been used to develop various strategies for targeted drug delivery, while controlling the release of drugs because of its many benefits. Here, a delivery system was designed to control drug release by external magnetic fields using porous silica and magnetic nanoparticles. Magnetic nanochains (MNs) of various lengths (MN-1: 1.4 ± 0.8 ㎛, MN-2: 2.2 ± 1.1 ㎛, and MN-3: 5.3 ± 2.0 ㎛) were synthesized by controlling the exposure time of the external magnetic force in magnetic nanoaggregates (MNCs). Mesoporous silica-coated magnetic nanochains (MSMNs) (MSMN-1, MSMN-2, and MSMN-3) were prepared by forming a porous silica layer through sol-gel polymerization. These MSMNs could load the drug doxorubicin (DOX) into the silica layer (DOX-MSMNs) and control the release behavior of the DOX through an external rotating magnetic field. Simulations and experiments were used to verify the motion and drug release behavior of the MSMNs. Furthermore, a bio-receptor (aptamer, Ap) was introduced onto the surface of the DOX-MSMNs (Ap-DOX-MSMNs) that could recognize specific cancer cells. The Ap-DOX-MSMNs demonstrated a strong therapeutic effect on cancer cells that was superior to that of the free DOX. The potent ability of these MSMNs as an external stimulus-responsive drug delivery system was proven.

With explosive growth in the area of the Internet and IT services, various types of digital contents are generated and circulated, for instance, as converted into digital-typed, secure electronic records or reports, which have high commercial value, e-tickets and so on. However, because those digital contents have commercial value, high-level security should be required for delivery between a consumer and a provider with non face-to-face method in online environment. As a digital contents, an e-ticket is a sort of electronic certificate to assure ticket-holder's proprietary rights of a real ticket. This paper focuses on e-ticket as a typical digital contents which has real commercial value. For secure delivery and use of digital contents in on/off environment, this paper proposes that 1) how to generate e-tickets in a remote e-ticket server, 2) how to authenticate a user and a smart card holding e-tickets for delivery in online environment, 3) how to save an e-ticket transferred through network into a smart card, 4) how to issue and authenticate e-tickets in offline, and 5) how to collect and discard outdated or used e-tickets.

Global Electronic Trading means that trading partners trade each other via Global Electronic Trading Network, that is, global business to business electronic commerce. Electronic payment systems are how to make payment electronically in manner that is efficient, reliable, and secure. I suggest the Electronic payment systems such as TradeCard and SWIFT enable seller and buyer to conduct and settle international B2B electronic commerce in case of solving the above problems. And, where the cargo arrives ahead of the B/L, the importer cannot take delivery of the cargo without the B/L. This situation is referred to as the B/L dilemma. But the BOLERO system will resolve this B/L dilemma. Bolero Project is developing a cross industry utility platform for the secure, electronic transfer of commercial trade information world wide.

인터넷의 보급으로 인한 전자 메일의 증가가 급증하고 있다. 컴퓨터 통신망을 통해 주고받는 전자 문서에 대해 문서의 내용과 그 문서가 배달되었음을 증명해주는 현행 우편제도하에서의 특수우편물 취급 서비스가 그대로 적용될 수 있다. 본 고에서는, 이러한 서비스를 고려한 기존의 전자우편 방식들을 조사 분석하여 정리하고자 한다. 분석된 자료들은 전자 우체국의 구현이나 실현을 위해 활용될 수 있으리라 생각된다.

The power consumption of 3D many-core processors can be reduced, and the power delivery of such processors can be improved by introducing voltage island (VI) design using on-chip voltage regulators. With the dramatic growth in the number of cores that are integrated in a processor, however, it is infeasible to adopt per-core VI design. We propose a 3D many-core processor architecture that consists of multiple voltage clusters, where each has a set of cores that share an on-chip voltage regulator. Based on the architecture, the steady state temperature is analyzed so that the thermal characteristic of each voltage cluster is known. In the voltage scaling and task scheduling stages, the thermal characteristics and communication between cores is considered. The consideration of the thermal characteristics enables the proposed VI formation to reduce the total energy consumption, peak temperature, and temperature gradients in 3D many-core processors.

This paper describes a neural stimulation system that employs an inductive coupling link to transfer power and data wirelessly. For the reliable data and power delivery, a self-referenced amplitude-shift keying (ASK) demodulator and a wide-range voltage regulator are suggested and implemented in the proposed stimulator system. The prototype fabricated in 0.35 um BCD process successfully transferred 1.2 Kbps data bi-directionally while supplying 4.5 mW power to internal MCU and stimulation block.

The demand for stable plasma has been on the rise because of the increased delivery power amount in the chamber for improving productivity, and fast and accurate plasma impedance matching become a crucial performance measure for radio frequency (RF) power system in semiconductor manufacturing equipment. In this paper, the overall impedance matching was understood, and voltage and current values were extracted with voltage - current (VI) probe to measure plasma impedance in real-time. Actual matching data were analyzed to derive calibration coefficient for V and I measurements to understand the characteristics of VI probe, and we demonstrated the tendency of RF impedance matching according to changes in load impedance. This preliminary empirical research can contribute to fast RF matching as well as advanced equipment control for the next level of detailed investigation on embedded system based-RF matching controller.
