This study is considered about the Taekwondo(跆拳道) uniform classified by period and analyzed the current Taekwondo uniform. And founded on this contents, new designs of uniform, that a functional side are considered and can symb이ize the identity of Taekwondo, are presented through this study. Ancient times to the present time, the Taekwondo uniform classified into three types according to 'Period of putting on our nation's costume'(three kingdoms${\sim}$Joseon(朝鮮) times), 'Period of confusion on uniform'(Japan's colonial rule of Korea${\sim}$-the early 1970s), 'Period of the settlement on official uniform'(the late 1970s-the present time). And besides, the shape of our nation's costume in ancient times is succeeded until Joseon times and this basic style becomes the outset on the current Taekwondo uniform. The designed uniforms are connoted the notion of the aesthetic appreciation in Korean traditional costume, that is, a symbolic, dignified, moderate appreciation with the consideration of a functional side for Taekwondo. And the contents on the presented designs are classified into 'shape, pattern, color'. First, these designs that are adapted the shape of Baji(바지) Jeogori(저고리)-belt, which have symbolized our nation's costume, and the shape of Bacja(배자) had used in Joseon times, are connoted a 'traditional appreciation with functional side'. Second, these designs, which are adapted the patterns of the active image(a bugbear, flying horse, tiger for embroidered patches, Taegeuk(太極)) in a modern style, express a 'symbolic, dignified appreciation'. Third, these designs are well-matched a black and white color with multicolored stripes(saekddong, 색동), and its ones are connoted a 'moderate and symbolic appreciation'.

In this study, researcher intended to extract the major factors of makeup design from Yangju-beolsandaenori-tal(masks) and Songpa-sandaenori-tal which have been handed down to the present among many kinds of the Korean folk masks, and to apply those factors to the modernization of traditional culture in terms of makeup design. The 17 Sandaenori-tals exhibited at 'The special exhibition of the Korean folk masks' in 1981 by the national folk museum of Korea were selected as the objects of this research. The formational analysis in terms of shape, color and material was conducted. The 5 factors of this analysis are as follows; face and hair, forehead, eye and eyebrows, mouth and nose. The beauty expressed in Sandaenori-tal includes naturalness, eccentricity and good-humor. The human feelings are expressed candidly and simply through naturalness. The eccentricity in Sandaenori-tal overemphasizes the shape of mask unsymmetrically. And it is expressed ghostliy in black, white and red colors. The good-humors in aesthetic viewpoint was expressed in surprised faces and innocent smile. Researcher applies the good humour to the art makeup in strong natural colors and shapes.

Understanding the exhaust gas recirculation (EGR) cooler fouling in diesel engine is important factor in the durability characteristic of a EGR system. We develope a test rig and PM feeder using carbon black to examine the effect of fouling on EGR cooler devices those were consisted of flat and shell & tube type. The EGR cooler fouling process is a complex interaction involving heat exchanger shape, boundary condition, constitutes, chemistry and operating mode. As the soot deposited to EGR cooler, these formed a thin deposit layer that was less heat exchange than the fresh status of tube enclosing the exhaust gas, resulting in lower heat exchange effectiveness in both type coolers. But these deposits caused different results in pressure drop, it is increased in flat type, but decreased in Shell & tube type of EGR cooler. A cause was estimated from a change of the flow structure and a decrease of contact area as the EGR cooler fouling.

Psenes maculatus and P. cyanophrys of family Nomeidae were collected for the first time off the coast of Tongyeong, Kyongsangnam-do, Korea. Specimens were catched with drifting seaweed patches on June and July, 1998. Young Psenes maculatus has six black bands ('<' shape) on the body, and 'Ttimul-reung-dom' is proposed as the Korean name. Psenes cyanophrys differs from P. pellucidus in having a compressed oval body shape scales on the check, and 16 longitudinal lines on the body. 'Jul-mu-nui-mul-reung-dom' is proposed as the Korean name.

In August 2001, pod rot of cowpea caused by Choanephora cucurbitarum was found in the experimental fields of the Gyeongsangnam-do Agricultural Research and Extension Services, Korea. Initial symptoms of the disease were the appearance of water-soaked, dark-green lesions and followed by rapid rotting of the infected tissues. As the disease progressed, whitish mycelia and monosporous sporangiophore with monosporous sporangiola were produced on the lesions. The fungus produced white to pale yellowish brown mycelia with scattered monosporous sporangiophore and monosporous sporangia containing sporangiospores on potato dextrose agar (PDA). Monosporous sporangiophore was long, slender and branched at the apex, with each branch bearing a sporangiospore. Sporangium was subglobose in shape and 42.6-112.6 ㎛ in size. Monosporous sporangiola were elliptic, fusiform or ovoid, brown in color, and 9.8-23.4$\times$7.2-12.8 ㎛ in size. Sporangiospores were elliptic, fusiform or ovoid in shape, dark brown or brown in color, 12.9-24.6$\times$8.6-15.4 ㎛ in size, and had three or more appendages. Zygospores were black and 43.6-72.4 ㎛ in size. The fungus grew on PDA at 15-40$\^{C}$, and optimum temperature was 30$\^{C}$. This is the first report on pod rot of cowpea caused by C. cucurbitarum in Korea.

A new anatomical head model was implemented based on the MR and CT images of the head of a volunteer whose head shape is close to the domestic standard. In order to compare SARs (specific absorption rates) of heads with different shapes, we calculated SARs in the two anatomical head models. The one is the new model and the other is that of the black race and was made at National Library Medicine in USA. The head model and a phone model were arranged in the computational space to be the touch or cheek position of CENELEC (European Committee for Electrotechnical Standardisation) and FCC guidelines. From the obtained results, we can see that the smaller head produces the higher whole head-averaged SAR. However, it seems that the localized SAR averaged over 1 g or 10 g is more dependent on the shape of the auricle rather than that of the head size.

The combustion chamber and nozzle of an end burning, small spherical rocket is designed. A spherical external shape has a number of advantages such as fixed center-of-gravity and minimum aerodynamic precession torques during flight and a better mass distribution for gyro-stabilization as contrasted to a conventional ogive rocket shape. It is shown that the cross-sectional variation of the end burning solid propellant with length is an exponential geometry to provide a constant thrust-weight ratio of the rocket device during the propellant burning period, and that the factors which affect the attainment of the constant relationship of thrust to weight in the design are the initial propellant area, initial weight of the rocket and propellant density. The measurement of the transient thrust in the ground static test using black powder propellant supports the predicted results. A wind tunnel having a $30{\times}30{\times}75cm$ test section and Mach number 0.11 is constructed, and a simple balance-type device is designed for the measurement of the drag of a spinning sphere. The experimental results indicate that the. spinning has no effect on the magnitude of the drag up to the Reynolds number $3{\times}10^5$. Numerical computation of the flight trajectories for various launching angles is presented, and the gyro-stabilization of spinning sphere is discussed.
