The purpose of this study was, as an experimental one, to suggest concrete ways to use computer in fashion design from information collection to design completion, and to present a real example based on the suggested ways. The first step to attain the purpose was gathering various sorts of worldwide fashion design information on the Internet, and then the collected data were inserted in a graphic file. Next, two methods of fashion design that use computer graphics were recommended : one was to produce fashion design just by altering some of the inputted Internet fashion materials, and the other was to do it after selected basic materials were put in database. Those methods could enable one to do fashion design just with rearrangement and smallest change of the prepared basic materials, without drawing directly, and at the same time, they could minimize time and efforts required for computer fashion design.

In off-set printing or coating process, it transfers ink on plate by rolling system. As Ink flows between rolls have an influence on printability of the final products, it needs to be studied scientifically and then control its values. Ink flows between rolls are processed under the effect of diversity factors such as rhelogical properties, printing speed, temperature, humidity etc. Therefore, this study try to approach the real ink transfer mechanism to be concerned about all sorts of variables.

In this work, $TiO_2$ nanoparticles were synthesized using $N_2-diluted$ and Oxygen-enriched coflow hydrogen diffusion flames. The effect of flame temperature on the characteristics of the formed $TiO_2$ nanoparticles was investigated. The measured maximum centerline temperature of the flame ranged from 2,103 K for oxygen-enriched flame to 1,339 K for $N_2-diluted$ flame. The visible flame length and the height of the main reaction zone were characterized by direct photographs. The characteristics of synthesized $TiO_2$ nanoparticles were analyzed by SEM and TEM images. From these images, it was evident that the formed nanoparticles were divided into two sorts. In the higher temperature region, over the 1,700 K, $TiO_2$ nanoparticles having spherical shapes with diameters about 60 nm were synthesized. In the lower temperature region, below the 1,600 K, the diameters of formed nanoparticles having unclear boundaries were ranged from 35 - 50 nm.

Despite of the introduction some sorts of the contract and the bid method like CM(Construction management) that will be efficient to manage the construction project. Korean agencies limit to control project management to do large public constructions. In the case of Taiwan, THSRC is apply J/V system in the public construction project, they are accomplishing that expend optimal the cost and save the construction time. To success J/V it has two factors, one is risk management and another is sharing information of construction project. Therefore, we will study to introduce J/V system to our construction project.

This paper deals with the design and control of passive multiple trailer systems for practical applications. Due to the cost and complexity of the trailer mechanism, passive systems are preferred to active systems in this research. The design and control objective is to minimize the trajectory tracking errors occurring in passive multiple trailers. Three sorts of passive trailer systems, off-hooked, direct-hooked, and three-point, are discussed in this paper. Trajectory tracking performance and stability issues under constant curvature reference trajectories are investigated for these three types. As well, various simulations and experiments have been performed for each type. It is shown that the proposed off-hooked trailer system produces a tracking performance that is superior to the others.

The Palaces of Chosen dynasty in Seoul had lost its original features. The external appearance of the buildings that remains in palace nowadays, have got former conditions, but its enteriors are reconstructed or removed So we have a little knowledge of interiors of palace buildings, expecially of the door and window system. To clear up ambiguity of what kinds of door are selected, and sorts of using methods are prevailed, we must persuit from the latest building to the older building, and compare with documents. For that purpose the Chukchodang of Toksu palace is selected, which reconstructed in 1904, and compared with the document published in 1906. The consequence of investigation is that the palace buildings were adopted double or triple window system, and the main room have buffer zones, such as corridors or small rooms. And the main rooms were facing with wall paper, so metal fittings are hidden and wooden surfaces are hardly expose for the purpose of amenity.

The author assumes that pure liquid metal is composed of molecular oscillators whose energy states are classified into two subgroups, i.e., A and B states, each being accesible to either one of the two sorts of lattice sites. The partition function involves constants characteristic of substance, which are obtainable from the Debye characteristic temperature assigned to its solid state. Calculation has been made for the various thermodynamic properties such as the vapor pressure, the entropy, and the heat capacity of liquid metals of GroupⅠelements over the temperature range from the melting points to the boiling points. The theoretical values thus obtained are in good accordances with those observed, within experimental error, although a slight derivation is observed in the atomic heat capacity.

Recently, the study for practical construction application no recycled aggregate concrete is actively being proceeded, on the purpose of technical development for recycling on the construction waste concrete occurred at the time of destruction of building construction by the rapid increase of building wastes and exhaustion of natural aggregates. But, the durability of investigation with all sorts of fluidity and engineering property for application recycled aggregate concrete to practical construction must be done at the same time. Especially, because of the real condition for chemical attack of concrete construction by the acid rain, acidification of soil, deepening of air pollution and dirty water etc. being come to the fore a serious problem, the study on the chemical soundness of concrete durability must be accompanied. This study is composed as: I series: Analysis for chemical soundness of aggregates. II series: Analysis for chemical soundness of natural and recycled aggregate concrete against $Na_2$$SO_4$ solution in drying and wet curing condition ($at20~80^{\circ}C$).

It is necessary for decrease of building waste to increase using of recycled aggregate. However, the quality of those recycled aggregates is not good enough. This study aim at the rise of the quality through abrasion test and researching the characteristic change of the test. The samples of recycled aggregates had been divided into 10 sorts by the amount of cement paste, and then the abrasion rate of those divided aggregates has been figured out through this experiment. The result of this experiment shows that the quality of the recycled aggregates has been improved.

Present all sorts of failure or no failure test methods are done for evaluate structural ability of pavement. It are Plane Plate Test, CBR Test, Benkelman Beam Test, FWD, Dynaflect, etc. but, each method of test not expect compatibility because the result very different by each method of test. Now among pavement's method of evaluation, no failure test gradually use because It quickly and simply obtain pavement's elastic modulus of each layer. But, It accompany expensiveness equipment, and It's degree of trust is lower against expensiveness equipment. Therefore this research practice comparative trustworthy Plane Plate Test, comparative low cost and quick Small FWD Test. And analyzed relation of Plane Plate Test with Small FWD Test.
