This study aims to analyse a trend of exoticism which is often mentioned in the contemporary western fashion. I analyse the internal elements of the exoticism in the fashion. By applying these elements to the exoticism of modern fashion, I intended to make it a useful instrument fur interpreting modern fashion. The results of this study are as follows. The internal elements of exoticism are summarized as escapism, curiosity, fantasy, hybridism and pluralism. 1. From the 19th century to the 1960s . The exoticism shown in the western fashion are influenced by such elements as curiosity and escapism. And diverse and plural exotic elements added a fantastic element to the exoticism. 2. After 1960s : Escapism acted much more because people thought exoticism offer a refuge from overall social problems of modern consumer society. Late in the 20th century, fantastic and hybrid element became more prominent in exoticism. And I found pluralistic view point was the other element of exoticism.

The purpose of this study is to set up a model of affective evaluation to structurally and systematically analyse subjective affective expressions of human beings with regard to the residential environment and to analyse the correlation between affective responses of residents and physical elements by positively applying the model to the evaluation of outdoor space of apartment complexes as an area of study on evaluation of residential environment. The area for evaluation was limited to three apartment complexes situated in Daegu, and the subjects for evaluation were also limited to a group of residents(housewives) living at the three apartment complexes. The research method is summarized as follows. 214 affective words(adjective phrases) expressing outdoor space of apartments were selected from literature on random sampling basis, and reduced to 25 ones through factor analysis. Then, these 25 words were systematized by an affective evaluating scale with 7 categories of meaning. The evaluation was conducted with 324 homemakers living at the apartment complexes selected for evaluation from September 29, 2000 to October 5, 2000. SPSSWIN, a statistical program was used for analysis.

Characteristics of the high frequency and pulsatile flow investigated experimentally to understand the flow phenomena in the hydraulic system. In the study, I axis fatigue tester which are widely used for automobile filed are selected. 4 Pressure transducer, amplifier, A/D convertor are used to analyse and to obtain the pulsatle pressure waveform with high frequencies in hydraulic system. Matlab are used. to analyse the characteristics of frequency. Variation of pump input pressure and actuator acceleration frequency, pressure wave are measured with or without accumulators. For with accumulator, frequency amplitude of pressure are very lower than those of without accumulator due to absorbing function of accumulator. As the actuator acceleration frequency increased, effect of accumulator are very important to decrease the pulsatile pressure waveform with high frequencies.

IEC 60300 is an advanced Dependability Management System(DMS) designed for highly qualified company. ISO/TS 16949 is an Quality Management System enforced reliability activities. It is now hot issue how to set up and implement DMS. This paper presents an approach for implementing Dependability Management System(IEC 60300) based on Quality Management System(ISO/TS16949). We analyse the difference and relationship between these two systems, and suggest an quantitative method for evaluating DMS by introducing MIR(Maturity Index for Reliability). Finally we analyse the level of reliability activities in these systems by MIR.

A heating cargo is solidified by several reasons during carriage. This study is to analyse a cargo accident which 811,202 US barrels of Nile Blend crude oil reamined solid In the tanks after discharge. There are some possibilities that low temperature of Beading cargo below cloud point and wax appearance temperature at loading time, heating interruption during voyage or discharging, and prohibition of crude oil washing during discharging might influence the cargo solidified. But we concluded that the defect of heating system would most affect the heating cargo solidified locally, and which blocked drain hole of bottom transverse and web frame and they obstruct flow of heating cargo in the tanks.

In this paper, the correlation between the vibration characteristics of the track components and the parameters affecting the vibration is analysed. To do it, the accelerations of each track component such as rails, sleepers and ballast are measured in Kyong-Bu high-speed railway lines. The RMS values of the measured data are calculated and the corrugation, the track irregularity and the pad stiffness are considered as the parameters in the viewpoint of track. By using the linear regression, the correlation coefficient is calculated to analyse the relationship. The parameter whose correlation coefficient is more than 0.7 is considered as the major one. Also, the 1/3 Octave analysis is calculated to analyse the dominant frequency band of the vibrations of the track components.

This paper described the verification of modeling technique of underground distribution from comparison between field test and simulation. It needs more exact transient phenomenon analysis model to establish lightning protection of underground distribution line. Although, there were a lot of transient phenomenon researches, nobody could has verified the confidence of modeling from field tests in interior until now. So, simulation model verified field test is needed to analyse transient phenomenon of underground distribution system. The examination must be accomplished in many different condition before suggesting these verified analysis model. In this paper, the conditions were examined and the various data results on the different line composition was compared with the EMTP simulation, when the lightning impulse test was accomplished at underground distribution line. Also the value between field test and simulation was very closed and the method of modeling has demonstrated confidence, when the method is used to analyse domestic transient phenomenon of underground distribution.

The battery pack, a main component of NEV(Neighborhood Electric Vehicle), needs cooling system when it is charging or discharging to prevent the degradation of the battery charging efficiency. The purpose of this study is to analyse the effects of cooling methods, changing positions of inlet and outlet and changing area ratios of inlet and outlet. It has been observed that in the point of uniform cooling suction from the exit side is more efficient than blowing from the inlet. And there is a suitable inlet/outlet area ratio in maximizing the mass flow rate. The numerical analyse using a commercial code STAR-CCM+ version 4.02 were used for the study.
