This paper will discuss how the structure and theme develop and compare between the Beowulf and Sir Gawain and the Green Knight. Sir Gawain and the Green Knight is generally considered as the finest of the English romances. The striking feature of this poem is its tight and organized structure, whereas most of the romances are loose in structure. This poem is composed of four fits containing traditional elements of romance: the Beheading Game; the Temptation and Hunting; the Exchange of Winnings; Returning. This process is linked together systematically, and as it goes on, certain external elements of romance come into view. There are heroic ideal, Christian humiliation and chastity, so the two themes or motifs are combined to produce a work of impressive organic unity.

Polypyrrole(PPy) was composite with MWNT to attain cycle stable by chemical method. We have been considered PPy is the ideal material for high energy density electrochemical capacitor due to pseudo capacitor reaction. In this study we found that increase in cycle life due to composite MWNT. Also PPy/MWNT composite material have resulted larger capacitance and exhibits better electrochemical behavior. The structural feature was investigated by using SEM and TEM. The PPy/CNT composite is not only a promising ultracapacitor material for energy storages but also has a good possibility because of its great capacitive properties, simple preparation and low cost.

This paper proposes an ATM switch architecture called Output Queued Batcher-Banyan switch (OQBBS). It consists of a Sorting Module, Expanding Module, and Output Queueing Modules. The principles of channel grouping and output queueing are used to increase the maximum throughput of an ATM switch. One distinctive feature of the OQBBS is that multiple cells can be simultaneously delivered to their desired output. The switch architecture is shown to be modular and easily expandable. The performance of the OQBBS in terms of throughput, cell delays, and cell loss rate under uniform random traffic condition is evaluated by computer simulation. The throughput and the average cell delay are close to the ideal performance behavior of a fully connected output queued crossbar switch. It is also shown that the OQBBS meets the cell loss probability requirement of $10^{-6}$.

Lee Sang, one of the representative poets of Korean Modern Poetry, wrote poems which present the existentialistic modernism in the 1920s, the chaotic era of Korean history. The characteristics of his works have been shown by various points of view. This paper especially explored the meaning and feature of mathematical expressions by numbers, symbols and other signs of mathematics in Lee's poems. His poems are composed by scientific and abstract rules in mathematics which are expressed as mathematical symbols. The paper focuses on analyzing seven poems which maximizes mathematical expressions among his poetry. This kind of work would be the one of ways to figure out the features of mathematics through literature.

This study examines whether English users at a U.S. university apply avoidance strategy in using English articles. All participants had learned English for at least 10 years and had used English for at least 15 years at the time of the data collection, so they made an ideal sample to examine the differences between native speakers of English and non-native speakers of English, in terms of avoidance strategy usage of English articles. To examine whether non-native speakers avoid using a certain feature when unsure of the correct usage, the mean differences of each article usage between NS and NNS groups were calculated and compared. On the basis of results showing that there are no statistically significant differences in terms of article usage between the groups, it is concluded that the highly advanced level participants did not use avoidance strategy in English articles, and that the type of English article and the task type did not affect learners' avoidance strategy usage. This research is expected to provide teachers and researchers with information about highly advanced level L2 language speakers' usage patterns with regards to avoidance strategy.

The electrical curtain is an electronic product which is most suitable for the sphere of intelligent home network. It provides the basic feature of intelligent home network such as the followings; various functions, powerful control. It also becomes the ideal technology with inexpensive power-line protocol, energy saving and solar power generation. Generally it is a suitable motor for BLDC to move the electrical curtain, because it provides the maintenance without difficulty, long-lived use with good efficiency. On this paper, we proposed the BLDC motor controller designed by CDM(Coefficient Diagram Method) and evaluated its performance with a simulation of the plant, designed the electrical curtain using BLDC motor and powe-line protocol.

The purpose of this study is to suggest the direction of the future fashion by grasping the cyber fashion, which is discussed outstandingly in the recent fashion world, into internal expression and external features. The result of this study is as follows: Cyber fashion means the application of the electronic image, dynamic phenonmenon of machine, and the effects of light to fashion, and it has some external features of geometrical pattern, dynamic structure, and high-tech material and color: Aside from this noticeable characteristics, cyber fashion has some internal features of the direction toward future, the anti-culture, and the surreal. In this cyber fashion, first, computer will be introduced and used as the means to realize a dream of human being. Second, it will be designed with the ideal feature of future society. Third, it will be possible to develope material and design to solve ecological issue of human beings. Fourth, the fashion to give the peace and stability to human being will be popular.

Wabi-Sabi is the most conspicuous and characteristic feature of what we think of as traditional Japanese beauty. It occupies roughly the same position in the japanese pantheon of aesthetic values as do the Greek ideals of beauty and perfection in the West. All things air impermanent. All things are imperfect. all things are incomplete. it offers an aesthetic ideal that uses the uncompromising touch of mortality to focus the mind on the exquisite transient beauty to be found in aoo things impermanent. Wabi-Sabi is a beauty of things imperfect, impermanent, and incomplete. It is a beauty of things modest and humble. It is a beauty of things unconventional. Wabi-Sabi is the art of everyday life. These may be the methods for the relationship establishment between human and space on the ground of Wabi-Sabl concepts which is commonly found no in contemporary interior space in japan.

Abstract - An electronic starter using MOSFET has been designed to take advantage of ideal preheating and starting features which can extend the lifetime of fluorescent lamps. The preheating circuit of the developed electronic starter is consisted of four parts - afull-wave rectifier circuit, an FET switching circuit a timer circuit for the gate switching, and a circuit for end-of-life protection. The circuit is analyzed by using PSpice simulation, and is improved to give an appropriate starting-time through control of R-C time constant of the timer circuit. And the circuit is also provided with an end-of-life protection feature, which utilizes the negative resistance characteristics of a thermistor that is thermally linked to FET through a heatsink. This also protects the FET from any overheating problems. From the results of simulation it is possible to obtain an appropriate value on the starting time for proper ignition and also it is verified that the limit for resistance of the thermistor is dependant on the value of resistance is the timer circuit
