We investigated temporal changes of growth of hydrophytes, aquatic biota and absorption of nutrient depending on planting mat type (synthetic fiber, coconut fiber) of artificial vegetation island (AVI) through pilot test using AVI miniatures in Kyungan Stream area of Lake Paldang. There were not significant differences of the water quality parameters (DO, pH, conductivity, turbidity, temperature), phytoplankton and zooplankton abundance among AVI miniatures and control station. The benthic macroinvertebrates showed most individual numbers in the miniature which was made by synthetic fiber and planted with Phragmites australis. The average and maximum height of hydrophytes in AVI miniatures was similar except one miniature where Phragmites australis was planted in synthetic fiber mat and grew more slowly. The adsorbed amount of nutrients and microbes in coconut fiber mat were larger than those in synthetic fiber mat regardless of trophic state of installed waterbody. The continuous increase of adsorbed amount of nutrients and microbes of coconut fiber mat for 8 months in an oligotrophic lake indicates that coconut fiber mat is suitable for the planting mat of AVI in an oligotrophic lake where nutrients are limited for growth of hydrophytes.

The purpose of this study is to investigate the relationship between costumes of court masque and the fashion trend at that time, by the analysis of the portraits. The period in this thesis is from Elizabeth I (1588-1603), until James I (1603-1625), when Inigo Jones was actively involved in court in masque, and when the traits of court masque began to appear in costume. The research material of this thesis is from the papers, costume design sketches, portraits and miniatures. As a result the costume of court masque which is the mixture of that of ancient Greece, Rome, middle age, and the exotic style of Ireland and Persian, had a great impact on the general fashion, and the unique pattern f costume became prevalent in the end of 16th and the early 17th century. This thesis might help us understand and special costume of that age and study the way how it come to have an influence on the fashion of the costume pertaining mainly to the privileged class.

During the Chosun(조선) and Ming(명) Dynasty, embroidered patches called hyoong bae(흉배), were worn on the front and back of official robes worn by courtiers based on class distinction. It was discovered in Jip Sah(Genghis Khan's history books) that the miniatures, patterns used in the Won(원) Period, were passed down to the Ming Dynasty in the $14^{th}$ century. Shape patterns included circles, triangles, squares, and ovals. Other patterns included dragons, deer, leaves, and branches. However it was found that there was no class distinction in wearing these patches. Out of 14 different miniatur, 41 men had worn these patches.

The Tuned Pendulum Slab Damper(TPSD)system is mainly composed of suspended pendulum slab which was hanging with cable wire from the top floor of building without any extra loads structurally, and can be helpful to reduce vibration with effect of tuned mass damper function by the principle of pendulum movement. The experiment was performed with miniatures of the 30stories of steel structure building by the forced vibration test using shaking table, and the result was reduced about 42% of vibration. The purpose of this study was to make analysis of application of the TPSD system to new building and exist building against strong wind or seismic wave. The result of this study was that the TPSD system shall be satisfactory in field of execution, process control, safety and economical efficiency with saving up to 70% of construction cost.

In this study, a wind tunnel, that has been developed for experiments of wind turbine rotor blades, has been considered. The deviations of the measurements have been examined after this wind tunnel had been introduced and the measurements on it had been explained. Two different wind turbine rotor blades miniatures have been used for getting better results from the experiments. The accuracy of measurements have been experimented three times repetitively and examined statistically. As a result, wind speed values which this type of wind tunnel and wind turbine rotors need for starting, wind speed in the tunnel, temperature and moisture values, the number of rotor's revolution, and the voltage that is produced in 102 ${\Omega}$ resistance and current values have been determined to be fixed by measurements used. This type of wind tunnel and wind turbine rotor' performance difference and the difference of revolution figures have been determined to be fixed by measurements used.

Propagation characteristics of electromagnetic waves in lossy tunnels are analysed using Finite Element Method with edge basis function. According to the analysis lossy dielectric wall on the tunnel highly affects the characteristics of the waves in the tunnel. Also higer modes are separated using mode orthogonality principle, and the propagation characteristics of higer modes are investigated. To verity the numerical results, miniatures of the tunnels are constructed and measurements of the waves are accomplished.

디지털 문화재 콘텐츠는 현실에서 체험하기 힘든 문화재를 디지털 기술의 특성을 이용하여 사용자의 경험을 극대화할 수 있고, 문화재 보수, 교육 등에 활용될 수 있다. 그런데 기존의 디지털 건축물 문화재는 실재 문화재의 구조 및 구성을 무시하고 외형만 만들어져 있어서 다양한 형태로 바꾸어 활용하기 곤란하며, 디지털 건축물 문화재 자체가 가상공간에 존재하여 현실체험에 제한을 받고 있다. 본 논문은 사용자가 현실공간에서 부재 미니어처를 이용하여 미니어처 문화재를 조립하고 그 결과를 가상공간의 디지털 문화재로 연결하여 다양한 체험을 제공하는 시스템에 관한 것이다. 이로서 현실 체험과 가상 체험이 연결되어, 보다 효과적인 체험이 가능하고 건축 문화재에 대한 보다 전문적인 학습이 가능하게 된다.

Most of Rapid Prototyping (RP) process adopt a solid Computer Aided Design (CAD) model, slicing into thin layers of uniform, but not necessarily constant, thickness in the building direction. Each cross-sectional layer is successive1y deposited and at the same time, bonded onto the previous layers; the stacked layers form a physical part of the model. The objective of this study is to develop a method for calculating the rotation angle ($$\theta$_x, $\theta$_y$) of hotwire of the cutting system in the three-dimensional space for the Variable Lamination Manufacturing process using expandable polystyrene foam sheet (VLM-S). In order to examine the applicability of the developed method to VLM-S, various three-dimensional shapes. such as a screw, an extruded cross, and free surface bodies such as miniatures of the monkey(a figure of Sonokong), were made using the data obtained form the method.

Online business these days prone to approach their costumers with improved module and various interface via Internet. This is more than just an act of providing enhancement, but a mean of finding out the customer's demand by enlarging their selection. This, however, is related to the bits per second of supplemental service network.For example, supplemental services that were not possible in the 56K modem era are now possible due to the information super highway network. To grope for new means of approaching, the best way will be by developing media that will collect customer's demands. Until now, customer's demands were evaluated by miniatures of apartment building, model houses or rendered images produced by 3D graphic softwares and pictures. Analyses were not available until evaluation were produced.Nowadays, utilizing the advanced Internet interface tools and various new media, customers are sought before the construction thus various studies to full fill the customer's demands are in process. This study is on development of a virtual module utilizing activated web environment. Analysis modules repeating the changes in customers are expected to deliver us a new trend.

In this study, three isolated interior flat slab-column connections that include three types of shear reinforcement details; stirrup, shear stud and shear band were tested under reversed cyclic lateral loading to observe the capacity of slab-column connections. These reinforced joints are 2/3 scale miniatures designed to have identical punching capacities. These experiments showed that the flexural failure mode appears in most specimens while the maximum unbalanced moment and energy absorbing capacity increases effectively, with the exception of an unreinforced standard specimen. Finally, the results of the experiments, as wel l as those of experiments previously carried out by researchers, are applied to the eccentricity shear stress model presented in ACI 318-08. The failure mode is therefore defined in this study by considering the upper limits for punching shear and unbalanced moment. In addition, an intensity factor is proposed for effective widths of slabs that carry an unbalanced moment delivered by bending.
