The term 'modern', in broader sense, refers to the concepts like modernity, modernization, modernism and the like, which came from Westernization impling the recognition of indigenous culture as being inferior to Western culture by comparison along with the expanded influences of the Empire of Japan. These concepts, however, rather than evolving from Western standards, came into being as a form of civilization led by Japan which had already tasted the fruits of modernization by 1920s. Since 1920s, the policy of, so-called, reconstructing Asian countries by Japan came to create eastern way of modernism, as a new East Asian trend mainly revealed in China which was against colonization after Japan's invasion and conquest of Manchuria. Therefore, Eastern' modern' unlike Western one could be understood in the widespread terminology, 'Modern(摩登)' in Shanghai, reflecting consciousness like 'Fashion' or 'Trend' in female images on a variety of visual media. By 1930s it was the most notable that 'modern' was accepted as something similar with 'Fashion', or 'Trend' in sociocultural contexts. These atmosphere had led commercial arts to enable to communicate with the public in a great deal of supports and success in Shanghai which was widely regarded as the citadel for the inflow of Western culture, among which transformations in female images were remarkable as a representative form of culture. It is also remarkable that 'historical modernity' transforming from the feudal age to modern society was considered a synchronic modernity, and nationalism was regarded as a sort of being modern, while involved in the newly-changed female images as a fashion mode. Changes in fashion including hair style in Shanghai by 1930s, as a way of expressions showing what was modern through commercial artistic productions, were easily noticed in visual media as an outlet of modern women's inner desire revealing their pursuit for new mode of life in metropolitan cities. As a characteristic of the time creating a new code of visual female images, it is notable that there existed another form of 'modern' satisfying socio-cultural needs of the general public seeking for being 'modern'.

우리는 현재 디지털이라는 테크놀로지를 앞세운 디지털미디어시대를 살아가고 있다. 디지털 테크놀로지의 '탈물질성'을 바탕으로 미디어에 기반하는 인간의 감각은 그 어느 때 보다도 강력하게 확장되어 있고, 그 영향력은 모든 분야에 예외가 없다. 아날로그 사진의 출현 이후 미디어의 존재가 심각하게 회화의 정체성과 가치에 의문을 던졌지만, 디지털 사진의 출현은 그보다 더 본질적인 새로운 패러다임과 가치 창조의 바람을 일으키고 있다. 화학적 프로세스를 거치는 과거 아날로그 사진과는 다르게 디지털 사진의 실체는 0과 1로 대변되는 디지털 프로세스를 거치게 된다. 이는 원본의 손실 없는, 오히려 후보정을 통해 원본을 뛰어넘는 복사본을 창조 가능하게 함으로써 원본이라는 전통적 가치를 소멸시켜 버렸다. 이처럼 디지털 사진이미지는 아날로그 사진과는 본질적으로 다른 구조와 속성을 지니고 있기 때문에, 아날로그 사진과는 차별되는 미학과 존재가치를 지니고 있으며, 이에 따른 감각의 확장 역시 유래 없는 가능성을 보여주고 있다.

This paper presents experimental results carried out on the purge characteristic of the anodic dead-end mode fuelcell and how to improve the cell performance by pulsation effects. The dead-end mode fuelcell has some merits that a fuel supplying device is not needed and the cell power is higher than that in the open mode fuelcell. However, the purge is necessary for preventing the porous media from being flooded by liquid water formed in the channel. At this time, the un-reacted fuel is discharged with the liquid water together in purge process. The discharged fuel can make the fuel efficiency lower. Therefore, the number of purge times should be decreased for the better fuel efficiency. In this study, the outlet of the anode channel was equipped with a purge solenoid valve and a pulsation generator. The purge times was decreased when the current density decreased and operation pressure increased without the pulsation effects. In addition, when the pulsation effects such as various frequencies or amplitudes were applied, purge times was alleviated up to 40%.

Microwave wireless power transmission (MWPT) is a promising technique for low and medium power applications such as wireless charging for sensor network or for biomedical chips in case with long ranges or in dispersive media such. A key factor of the MWPT technique is its efficiency, which includes the wireless power transmission efficiency and the radio frequency (RF) to direct current (DC) voltage efficiency of RF-DC converter (which transforms RF energy to DC supply voltage). The main problem in designing an RF-DC converter is the nonlinear characteristic of Schottky diodes; this characteristic causes low efficiency, higher harmonics frequency and a change in the input impedance value when the RF input power changes. In this paper, rather than using harmonic termination techniques of class E or class F power amplifiers, which are usually used to improve the efficiency of RF-DC converters, we propose a new method called "optimal input impedance" to enhance the performance of our design. The results of simulations and measurements are presented in this paper along with a discussion of our design concerning its practical applications.

This study aimed to identify visuality changes in the $21^{st}century$ digital visual media art through the expension of digital frames based on visuality represented by Cartesian perspectivalism in the modern age. The visuality of perspective, camera obscura and panorama, which are called modern visual systems, was analyzed to illustrate each characteristic from a viewpoint of a seeing subject. These characteristics of the visual systems were restructured to meet the visuality of the digital era through the illustrations of Lacan's gaze. In addition, the characteristics of frames found in the $21^{st}century$ digital visual media art were identified, and they were categorized into and illustrated from physical, convergent and interactional viewpoints. The outcomes were classified into the $21^{st}century$ digital frame types, and new $21^{st}$century digital visual illustrations were suggested based on the results.

The idea of identification have become a subject of discussion ever since the time man started to contemplate on the meaning and value of his being. However, the concept of identity defined by theorists such as sociologists or cultural historians influence the consumption pattern of the major consumer group, in conjunction with the advent of the mass consuming age. The conflict and mutual realization among variable generations and residential areas of different. consumer levels profoundly affect the formation of the identity of the new generation and the role and experience of women. This series of transit is progressing more rapidly due to the characteristic situation of the expiration of a millenium. Advertising strives to control our interests and ideas on the products we choose to use and affects our identity by manipulating images of successful people. People tend to be influenced more significantly by the mass-culture than by people around them, such as family or friends, in rendering their self?identity; in which process, adopting the identity produced by mass-media and advertising. Such identity is conducted partly of the product identity and the stereotyped image suggested by mass-media. This study bears significance in the attempt to provide actual data and expand the realm of ideas and planning in future advertising through demonstrative analysis of self-identity creative in Korean TV advertising.

'Fantasy', the central notion of this essay, is discussed here more as a new paradigm in order to describe the structure of a work of art than as a stylistic characteristic proper to a specific genre of art. It means the whole situation and experience produced by two connected terms 'corporeal subject - screen'. Roland Barthes explained the 'semiographic painting' by Andre Masson as a field in which happens a certain connexion between the impulse of subject and the image, which views the painting not as a physical object but as a 'cinematic screen' ; painting may be redefined as a dream or a fantasy of the corporeal subject. And such an idea of 'art as fantasy' is closely related to the recent theoretical attempts consisting in abolishing the vision-centered conception of art since Renaissance. In this essay, the notion of fantasy as an aesthetic model is sketched by means of the Freud's notes on the fantasy 'A child is being beaten' and Lyotard's more advanced analyse on its attributes and operations. In Lyotard's analysis, fantasy is defined as a 'bloc' or a 'matrix-figure' featuring simultaneous conversion between the active and the passive, sadism and masochism, and coexistence of imcompossible meanings. In this sense, fantasy may be given to us as an analogical model from which we can outline the aesthetic characteristics of electronic media art involving virtual reality and interactivity.

In recent years new recording media and materials for head-disk interface (HDI) have been developed in order to increase the recording density of storage devices and decrease the cost of production. It is well known that HDI in hard disk drive (HDD) needs high durability and stability. The tribological characteristic of commercialized HDI systems is an important indicator of the HDD reliability. In this study, experimental investigation on the wear coefficient of commercialized hard disk slider pads was performed. The slider was placed on top of a hard disk and allowed to slide for a set distance. The wear of the pads was measured after the sliding tests. The result showed that the micro-bumps in commercialized HDD have extremely low wear coefficient of $10^{-11}$. The results of this work may be used for further development of the HDI technology for HDD.
