The style which is created by grafting the characteristics of goth onto haute couture designer works is called 'Haute goth'. The purpose of this study is to analyze the modem Goth fashion style based on Goth's historical background and characteristics. Also, I investigated the aesthetic characteristics of haute goth style appeared from the work of haute couture designers. Goth means a member of East Germanic people who invaded and settled in the Roman Empire from the 3rd to the 5th century. Goth style had been developed to the medieval European architecture style or the literature style of 18th~19th centuries and later it was reappeared in the gothic band in the late 20th century. Goth fashion shows the characteristics of the medieval times and Victorian times mixed with punk and fetish style. Goth fashion is expressed with the images of fear, darkness, mystique, dandy and eroticism. 'Dark esthetics' is realized through black clothes, pale complexion and silver accessories. Many designers like Alexander McQueen and John Galliano designed 'haute goth fashion' in various ways. The characteristics of 'haute goth' can be summarized in four things. It creates new images, seeks various changes and pursuits newness. It upgrades a street look style gothic fashion to a luxury high fashion and the creative design with artistic value. It also shows an experimental sprit by using a unique shapes, silhouettes, different materials and extreme images or creating new combination through the mismatch of opposite objects or emotions. Although it is rooted in the past because of the influences by late medieval times, Victorian times and Edwardian times, it displays enough of future-oriented historicism designs.

A novel three-phase four-wire inverter topology is presented in this paper. This topology is equipped with a special capacitor balance grid without magnetic saturation. In response to unbalanced load and unequal split DC-link capacitors problems, a qusi-full-bridge DC/DC topology is applied in the balance grid. By using a high-frequency transformer, the energy transfer within the two split dc-link capacitors is realized. The novel topology makes the voltage across two split dc-link capacitors balanced so that the neutral point voltage ripple is inhibited. Under the condition of a stable neutral point voltage, the three-phase four-wire inverter can be equivalent to three independent single phase inverters. As a result, the three-phase inverter can produce symmetrical voltage waves with an unbalanced load. To avoid forward transformer magnetic saturation, the voltages of the primary and secondary windings are controlled to reverse once during each switching period. Furthermore, an improved mode chosen operating principle for this novel topology is designed and analyzed in detail. The simulated results verified the feasibility of this topology and an experimental inverter has been built to test the power quality produced by this topology. Finally, simulation results verify that the novel topology can effectively improve the inhibition of an inverter with a three-phase unbalanced load while decreasing the value of the split capacitor.

The Bauhaus movement can be said to be the by-product of forming work pursued through the method of constituents even under endless discord between the so-called modern ages and anti-modern ages rather than to say that it was progressed consistently on the assumption of a design. Accordingly, all instruments of Bauhaus education which contributed to form the source of the modern ages realized educational value related to the actual problem at the point of time when the student evercomes all internal and production can be managed most effectively under one system was originated inevitably. The most exential point of the work of Bauhaus workshop is the fact that all products show homogeneity as time passes, which is appeared as the result of the spirit of consciously developed community based on cooperation between various characters and personalities. Also, the homogeneity does not exist in formative detailed aspect appeared externally but in the basis of effort having produced things simply and faithfully, and on the other hand, in accordance with essential rule. Therefore, the original form of Bauhaus products can be said not to be fashionable but the crystal of work process at the workshop through much thought and contemplation in view of endowed form following art, technology and economy.

This paper analyzes the long-run effects of an environmental tax levied on motor vehicles. If the government charges their consumers the tax as much as the monetary value of the external damage due to the pollutants emitted from motor vehicles, the operation of vehicles is reduced to the socially optimal level, alike to ordinary Pigouvian taxes. Thus, air pollution abatement is realized in the short run. Moreover, in the long run, the tax leads the consumers to prefer cleaner vehicles owing to the tax burden, and so the firms produce the motor vehicles with less pollutants emitted to meet the change of demand. Therefore, the tax has the additional effect on air pollution abatement. This result is obtained from the simulation in the oligopoly model which has an interior solution when the vehicles are horizontally and vertically differentiated.

Traditional music education for infants is the most important step of forming human knowledge. Since their rapid development of intelligence and emotion has an educational value not only it improves the human knowledge but also it makes infants understand the unique emotion of Korean people. Under the several circumstances, however, we have no enough contents for traditional music education. Thus, by researching and analyzing the existing educational contents and complementing them properly for multimedia environment as a form of animation, we perform a series of experiments to infants who are attending to the kindergarten with interactive animations which are familiar with infants. Infants become interested in the contents and after the lesson of the short bamboo flute content, they show the clear improvements for the playing on a musical instrument. This proves that the Korean music educational content realized with animation can be an alternative plan to improve the educational effect by causing enjoyment and interest of infants.

Unlike general unmanned aerial vehicles, the quad-rotor is attracting the attention of many people because of simple structure and very useful value. However, as the interest in drones increases, the safety and location of vehicles are becoming more important provide against aviation safety accidents or lost accidents. Therefore, in this paper, we propose a tracking system that stabilizes the model with a simple controller by linearized modeling and grasp tilt angle data from various sensor through the filter. The developed tracking system transmits the position of the quad-rotor in flight to the computer and shows it through the route, so it can check the flight path and various information such as flight speed and altitude at the same time. Then the sensor used in the actual quad-rotor can not measure exact sensor data for disturbance and vibration. So we use sensor fusion of Kalman filter and Complementary filter to overcome this problem and the stability of the quad-rotor hovering is realized by PID control. Through simulation, various information such as the speed, position, and altitude of the quad-rotor were confirmed in real time.

Various types of evidence suggest that some changes in cellular in cellular calcium may well signal the initiation of a chain of events leading to the physiological effects of the bone resorbing agents. The effects of 1,25-dihydorxycholecalciferol, $1.25\textrm{(OH)}_2\textrm{D}_3$, Ca ionophore A23187 and calcium antagonist, diltiazem on bone resprption and the cellular transport of Ca were investigated. Bone $^{45}\textrm{Ca}$ desaturation experiment was realized in isolated heterogenous rat bone cells after equilibrating the cells with $^{45}\textrm{Ca}$. Results of $^{45}\textrm{Ca}$ desaturation experiments were analysed by fitting the $^{45}\textrm{Ca}$ desaturation curve to a model of 2 exponential terms which indicated the presence of 2 exchangeable cellular calcium pools. $1.25\textrm{(OH)}_2\textrm{D}_3$ (0.5ng/$m\ell$) induced significantly bone resorption which was decreased by the physiological dose of diltiazeme(above 5nmol/$m\ell$) although it was ineffective alone. Ionophore A23187 (0.2$\mu\textrm{g}$/$m\ell$) decreased Ca release from bone but no additivity of effect with diltiazem(20nmol/$m\ell$) was observed. $1.25\textrm{(OH)}_2\textrm{D}_3$ (0.5ng/$10^{6}$ cells) had a moderate effect on the two kinetic phases of $^{45}\textrm{Ca}$ desaturation curve and these values were normalized when diltiazeme (20nmol/$10^{6}$ cells) was added along with $1.25\textrm{(OH)}_2\textrm{D}_3$. Ionophore($0.05\mu\textrm{g}$/$10^{6}$ cells) alone increased specifically the value of the slow turnover rate which was not affected by addition of diltiazem. The hypothesis concerning the involvement of calcium in bone resorption seems in fact to be verified in case of $1.25\textrm{(OH)}_2\textrm{D}_3$ but more unsettled for Ca inophore A23187.

A new control approach using neural network for the robust position control of a BRUSHLESS direct drive(BLDD) motor is presented. The linear quadratic controller plus feedforward neural network is employed to obtain the robust BLDD motor system approximately linearized using field-orientation method for an AC servo. The neural network is trained in on-line phases and this neural network is composed by a feedforward recall and error back-propagation training. Since the total number of nodes are only eight, this system will be easily realized by the general microprocessor. During the normal operation, the input-output response is sampled and the weighting value is trained by error back-propagation at each sample period to accommodate the possible variations in the parameters or load torque. And the state space analysis is performed to obtain the state feedback gains systematically. In addition, the robustness is also obtained without affecting overall system response.
