Electrowetting phenomenon is applied in the various field of technology. One of that is electrowetting display as a paper like electronic paper. Fast response and easy to express a color is goodness. In spite of that, the oil movement of the electrowetting display is irregular. So it doesn't look like uniform. Because of above reason, electrowetting display using patterned electrode is made and the characteristic of oil movement is observed. Electrode and polymer wall is patterned by photo-lithography. We analyze the oil movement according to the variation of size and the position of etched electrode area.

Economical consumption of energy, longer life of lamps, higher lighting comfort and new aesthetic of illumination is subject of numerous research and development works. The halogen lamps are an example of positive solution some of above mentioned problems. The electronic transformers are more frequent used for their supply. In comparison with conventional transformers they have less weight, less volume and 60% less power losses. Their advantages are particular visible, when the hybrid technique is applied. The paper presents the results of engineering research and development works carried out in Private Institute of Electronic Engineering, in R. & D. Center for Hybrid Microelectronics and Resistors and in Technical School of Communications in Krakow, in the field of the design and exploitation tests of hybrid converters 220V AC /12V DC (electronic transformers) and electronic ballasts destined for the supply of halogen lamps 20W to 150W and fluorescent lamps respectively. To perform the converters, thick film technology and surface mount technology were used. For the protection of converter electronic circuit the thick film temperature sensor and transistors were applied. Moreover the paper presents the base application circuits of elaborated converters, their technical parameters and exploitation results. The development perspectives of such domain of hybrid circuits are also discussed.

The main issues addressed in this paper are as follows : First, this paper makes a distinction among types of e-money, IC card type versus Network type, open-loop type versus closed-loop type, online type versus offline type and accountable type versus unaccountable type, and analysis the clear and accurate criterion. Second, generally speaking, e-money is a claim on originator of e-money and not legal tender, so, delivery of e-money by itself does not relieve of monetary obligation. Between it is not easy to define e-money, by now there are many definitions of e-money, there is a legal uncertainty accordingly and then it is not easy to find proper law applicable to resolve a particular issue. As a result. many problems relating to e-money would be solved through analogical application of the moot proper law among the laws that apply to the cash, check, credit card, or fund transfer after analyzing type of e-money at issue. This paper studies the methods on diffusion of the utilization of electronic money. To diffuse the usage of electronic money, it need; prerequisitely as a basic conditions independence of electronic money, non-reusability, and anonymity. And also as a additional conditions it need; usability in the offline commerce, transferability, divisibility. And now electronic money is used very actively, but still has many Jaw problems such as protections of consumer, law enforcement, supervisory, etc. So electronic money has called as money, but it is sure that electronic money is not a legal tender. So to facilitate the economic function of the electronic monel it is need to supplement the electronic money in the legal sides.

It is not a simple topic how let the modern readers read the past literature in the these days of digital. But even though the changes of the times, we must not let 'the paper-books(the thing written with letters)' disappear because of 'the audio-visual texts(the thing made with digital media as drama-opera, animated cartoon, animated image)'. The Electronic medias should be used so as helping for us to understand contents of the paper-books. Because of them, the paper-books must not be expelled. It is no need certainly for the reading materials to be made with Paper-books. For example, the electronic-books in order to read also would not become problems. Moreover, the electronic-books to be made with various electronic media can also provide the audio-visual materials for readers well to understand contents of the books. For that reason, the electronic-books would be helped to read effectively. Besides after reading the original texts, the readers to try the 'rewriting', with using the meanings for oneself to get from the texts would be able to make a synopsis or story-telling for other art performances. These works are things positively to be stimulated, because of giving the achievement motivations to the readers. To conclude, the audio-texts reading and the visual-texts reading should be developed so that the paper-books to be revitalize. And though the modern readers dislike to read the paper-books, We should try to make the audio-visual texts base on the paper-books. Therefore the paper-books and audio-visual texts are inter-complementary relationships, not competitive relationships.

As the scale of electronic commerce increases more and more, disputes in the electronic commerce also happen more frequently. As the development of electronic commerce is difficult without smooth settlement of dispute, the pursue of smooth settlement of dispute is very important. Regarding smooth settlement of dispute, the way of dispute settlement through Online Dispute Resolution(ODR) is pursued positively nowadays. However the responsibility of related parties still remains to complete such system. This paper divides related parties into the parties(seller, buyer), ODR providers, the neutral dispute resolver, and the governments. Later this paper examines the responsibility of related parties. As related parties complete their own responsibility, electronic commerce may develop more and more. Furthermore through the development of electronic commerce all nations will enjoy mutual benefit.

In order to construct a successful electronic commerce system, three main essential factors must be satisfied to obtain the best effective outcomes. The three main essential factors are as follows : economic factor, effectiveness factor and convenient factor. In order to understand the role of these three factors, one must have some insight knowledge about security to assist him to implement these three factors in his construction of an electronic commerce system. This paper analyses a implementation mechanism of security systems based on the SET 1.0 standard for electronic commerce systems, thus providing an effective plan for the construction of a security system in the SET-based electronic commerce field. This paper helps to analyse the elements of security vulnerabilities in the SET 1.0 standard implementation and also helps to understand the SET 1.0 protocol.

Research relevant to the electronic commerce tends to either overestimate or underrate the role of Information and Communication Technology (lCT). There is both technological skepticism within the social science circles and technical optimism within the engineering and computing field. Each perspective seems to have a limitation in adequately explaining the phenomenon of electronic commerce diffusion. Therefore, this research attempts to explore major characteristics of Web-based shopping systems as enablers of new business, concerning both the technical and business aspects in contemporary electronic commerce settings. On this basis, this paper addresses a configuration model of WBSS on the harmonious perspective concerning both the technical and business issues. It is our hope that both technical perspective and business perspective for exploring WBSS's configuration model presented in this paper can be an initial step towards a more balanced debate of ICT role, for electronic commerce.
