The transmission performance of TSV considering the effect of electronic-thermal coupling is an new challenge in three dimension integrated circuit. This paper presents the thermal equivalent circuit (TEC) model of the TSV, and discussed the thermal equivalent parameters for TSV. Si layer is equivalent to transmission line according to its thermal characteristic. Thermal transient response (TTR) of TSV considering electronic-thermal coupling effects are proposed, iteration flow electronic-thermal coupling for TSV is analyzed. Furthermore, the influences of TTR are investigated with the non-coupling and considering coupling for TSV. Finally, the relationship among temperature, thickness of $SiO_2$, radius of via and frequency of excitation source are addressed, which are verified by the simulation.

A multiple-electrode-type electronic paper film can implement a single color and control the transparency, as it has multiple electrodes in one cell. Therefore, it can be used as a transparent display. In this paper, we explain the structure and driving method of a transparent electronic paper display, and then propose a control method of transmittance. Subsequently, we verify the theory by measuring the transmittance via experiment. Thus, by changing the manner of applying the voltage to three lower electrodes and one upper electrode, transmittance in eight cases could be realized. It was confirmed that the transmittance derived from the experiment could be controlled from a minimum of 6.75% to a maximum of 71.18%.

The purpose of the study is to develop effective teaching methods to strengthen the major learning capabilities of electronic engineering learners through inquiry learning using computing thinking ability. To this end, first, in the electronic engineering curriculum, we performed teaching-learning through an inquiry and learning model related to mathematics, probability, and statistics under the theme of various majors in electronic engineering, focusing on understanding computing thinking skills. Second, an efficient electronic engineering subject inquiry class operation using computing thinking ability was conducted, and electronic engineering-linked education contents based on the components of computer thinking were presented. Third, by conducting a case study on inquiry-style teaching using computing thinking skills in the electronic engineering curriculum, we identified the validity of the teaching method to strengthen major competency. In order to prepare for the 4th Industrial Revolution, by implementing mathematics, probability, statistics-related linkage, and convergence education to foster convergent talent, we tried to present effective electronic engineering major competency enhancement measures and cope with innovative technological changes.

The realization of the Internet and Electronic Commerce through the progress development of the information & communication has changed the transition of the financial settlement system all of the world. And Electronic Commerce has becoming the most important tools to decide the value from the real money, existing bills, coins to the Electronic Money. Electronic Money is very useful materials with Electronic Wallet at cyber times in the future. So that reason, I studied Electronic Money's present situation & after development direction in Korea. And the purpose of this paper is to introduce Electronic Money's modem definition and to analysis the common use situation, operation at home and abroad at Electronic Commerce times. In add to investigated advanced countries Electronic Money utilization and drawed out current events point. So I suggest to this like point, in honour of Electronic Money's common use in Korea. First to establish universality. Second, to make various terminals and the powerful networking structure. Third, to establish stability. Fourth, renovating the system goes side by side. Futhermore, to develop Electronic Money's, it is necessary to make skilled labour and to learn foreign advanced technology.

Resorting to electronic arbitration to resolve disputes in international trade contracts is the most important reflection of technological progress on the reality of international commercial arbitration. Electronic is a modern image of traditional arbitration, and this type of arbitration provides many advantages that are not provided by any legal system for resolving disputes, including speed, effectiveness and lower costs. What will this development produce? Through technical progress in the means of communication, it has become conceivable that international trade dealers agree to arbitration via electronic means of communication, followed by the completion of the arbitration process via the Internet, leading to the issuance of the electronic arbitration award in an electronic manner as well.

Electronic publishing, vaguely defined area of activities and vaguely defined scope of products, is consisting of electronic or computerized processing of text, images, graphics for publication in one of electronic forms and also in a traditional printing on paper. As it is vague in scope, topics of this paper are of diverse interests. Technological developments related to electronic publishing are rapid in Japan. Activities and events by various organizations, both in the private sector and the public sector, are not few, and interlaced.

Where a paper document, a manual signature, or negotiability is required in statute, then solutions must be found through a change in the law. However, where the problem originates in commercial usage, then the solution can be easier, and speedy. Certainly, nearly all of the functions that paper document provides can be equally, or better, satisfied by electronic means. That is, Electronic Commerce(EC), which has been increasing rapidly and is a new type of transaction, may be hindered by legal obstacles to use of Electronic Message, or by uncertainty to its legal effect and validity. Therefore, it is important to sustain legal effect to Electronic Message for the prosperity of EC The one of solutions is to use reliable Electronic signature system by Certification Authority to verify the authenticity of Electronic Message.

Since the internet is open to public in 1990, electronic commerce(EC) user has increase rapidly. Now EC is considered not only as communication method but also as new economical activities. EC is a kind of new commerce model which uses electronic means. And EC has global characteristics so that many country's legislation which regulates it differently makes an obstacle to vital of EC. The purpose of this study is to examine legal problems of internet electronic commerce. First, there are some legal problems whether electronic document has same legal function like traditional documents. Second, electronic signature must has authenticity, integrity, non-repudiation, writing and confidentiality in order to use looks like common signature. Finally, electronic contract is concluded on principle of mutual agreement. It is apparent that the concept of arrival is applied to the date and place in conclusion of electronic contract.

Channel length dependence of NBTI (negative bias temperature instablilty) and CHC (channel hot carrier) characteristics in PMOSFET is studied. It has been considered that HC lifetime of PMOSFET is larger than NBTI lifetime. However, it is shown that CHC degradation is greater than NBTI degradation for PMOSFET with short channel length. 1/f noise and charge pumping measurement are used for analysis of these degradations.
