The subject of this thesis is a case of the present class researchers and teaching activities studied composition at the university, and analyze the historical background and cyclic form in ``Moving Figures`` of Yong-hwan Kim, (1988~ ) my student. The purpose of this thesis is to study the structure with cyclic form, harmony and study elements such as timbre on Yong-Hwan Kim‘s ’Moving Figures`` appear in each part of an independent study is to focus on the subject appears as a means of circulation that bind specifically to one picece of the total and individual characteristics. Thus, the university student majoring in composition classes, and helping in the details, particularly on aspects of teaching process. Originally cyclic form is the musical ideas from works such as the cantus firmus mass, in the 16th century parody mass of the 15th century. Composers of the classical era composer and romantic era, were used also as a way of putting a musical ideas first movement to appear in more than one subject, as well as other movements in the same piece of music in the form of a multi-movement sonata form and framework. But ``Moving Figures`` is unlike the original meaning of cyclic form, <introduction-A-B-C-A``-coda> consists of a total of six section of, and since the transformation, the development of the cyclic form is made only in the movement type, and cyclic form as a classical concept with a different sense, may be seen to have a little more advanced aspects. The musical structure used in contemporary music appears dissolved and established patterns, but ``Moving Figures`` is borrowing ideas from the classical form and transformation into comtemporary is thought to be the work that needs to be thoroughly studied. and also can be considered in analysis for contemporary musical composition trends with music educational aspects.

The effects of $CO_2$ enrichment on growth of rice (Oryza sativa L.) were examined. The plants were grown in growth chambers with a 12-h photoperiod and a day/night temperature of $28/21^{\circ}C$ of the seedling stage and $30/23^{\circ}C$ after the panicle initiation stage. The plants were exposed to two elevated $CO_2$ of 500, 700 ppm and ambient levels (350 ppm). At early growth stage of three varieties (IIpumbyeo, Chucheongbyeo, Hwaseongbyeo), the elevated $CO_2$ increased plant height, tiller, leaf area and dry weight. The photosynthetic rate was decreased at 24 days after treatment (DAT) compared to 11 DAT. The elevated $CO_2$ increased plant height and dry weight at panicle initiation stage (PIS) and heading stage (HS) of three varieties (IIpumbyeo, Chucheongbyeo, Hwaseongbyeo). The photosynthetic rate, stomatal conductance, evapotranspiration rate were decreased at the long days of treatment than that of short days. At entire stages, the elevated $CO_2$ increased the water use efficiency of rice plant because evapotranspiration rate was lowered at the elevated $CO_2$ than ambient levels.

Since J.B.Pendry proposed the concept of "perfect lens" there have been many researches which focus electric fields. However they used 1 dimensional lens. In contrast, this paper suggests 2 dimensional lens calculated from angular-spectrum method. 2-dimensional focusing is achieved in nearfield. This result implies that the proposed lens can be used for wireless power transfer, imaging system, and sensing systems.

The prototype of Korean high speed train (HSR350), composed of two power cars, two motorized cars and three trailer cars, has been designed, fabricated and tested. In this paper, the body vibration has been reviewed from the viewpoint of the vehicle's safety and the vibration limits for components and sub-assemblies mounted on the car-body using by the experimental method. And, the dynamic characteristics, such as jerk, natural mode and kinematic mode, have been reviewed. The KHST has been run to 300 km/h in the KTX line and the results of on-line test show that it has no problems in the vehicle's safety and the vibration limits. And the characteristics of body vibrations has been predicted at 350 km/h by fitting curve about the measured acceleration signals.

Recently "ride comfort" problem becomes increasingly important because of today"s needs for train speedup. The concept of term "riding comfort" is equivocal. Generally it is defined as the vehicle vibrat ion. There are many studies on evaluation method of ride comfort for railway. But each of them recommends the different assessment method and the different guidance. So users must review whether they can apply it to their system or not. In this paper, we discuss the evaluation methods defined in the standards - ISO 2631. UIC 513 R, CEN DRAFT prENV 12299 and the ride index suggested by Sperling.

The two projects about the high speed train have been performed in Korea, one project is the commercial run of high speed train(KTX) from Seoul to Busan and the other is the development of original high speed train(HSR 350x). As the successful results, the service run of KTX had been launched on the 1st of April, 2004 and HSR 350x had been fabricated in June, 2002 and has been tested in the Kyoungbu line and Honam line since then. The railway has the track irregularities which cause vibrations, such as rail joints, turnout, level crossing, transition curves and super-elevation ramps, and variations in the track level(z-axis) and the gauge(y-axis). Generally, the ride comfort for railway is evaluated by using the vibrations. In this paper, the ride comfort indices according to UIC 513R and ISO 10056 have been reviewed when the high-speed trains are operated on both Kyoungbu line and Honam line. Also, the ride characteristics for KTX and HSR 350x on the high speed line and the conventional line have been analyzed and evaluated. The results show that the high-speed train has no problem from the viewpoint of the comfort ride on the high speed line and the conventional line and the ride index for HSR 350x is same as that for KTX in the high speed(300 km/h).
