This study focus on the history of Scottish kilt and the application of kilt designed by Vivienne Westwood 1993 F/W. Up to late the 16 Century saffron shirt was worn among Highland men and belted plaid become common dress after the 17 Century. The early the 18 Century belted plaid have developed as a kilt separated to a upper and a lower skirt style. However Government banned wearing tartan and kilt after Culloden battle (1745) as highland Dress(tartan, kilt, belted plaid etc) was the symbol of rebellion. This legislation by Hanoverian authority continued for 35 years. Although most of tartan was disappeared during those period it has become popular among European upper class after george IV's visiting Scotlan in 1822. Highland Dress become Scottish national dress after Industrial revolution. Currently Vivienne Westwood's 93 F/W using tartan and kilt and its accessaries those items were successfully transformed modern ladies dress.

본 논문에서는 LED(light emitting diode)를 사용한 일반 조명에서부터 자동차 조명에 대한 LED, CNT(carbon nano-tube), OLED조명의 융합기술 현황에 대하여 살펴보았다. 정부의 15/30보급정책의 일환인 LED조명 시범보급사업(부산 및 대전 지하철역사, 김대중 컨벤션센터, 대구 및 대전 우체국 등)과 한국산업규격(KS C 7651-3)의 제정 등으로 LED 응용 조명은 시장에서의 사용으로 기존 조명기기와의 경쟁력이 예상된다.

Inductively coupled plasma is commonly used for electrodeless lamp due to its ease of plasma generation. Optical characteristics significantly depend on the RF power and gas pressure of the plasma. This paper describes the measurement of luminance as a function of RF power and gas pressure with a goal of finding optimal operating conditions of the electrodeless lamp. The gas pressure was varied from 10 [mTorr] to 500 [mTorr] and the RF power was varied from 10 [W] to 200 [W]. It was found that the luminance tends to be decreased when argon pressure is increased, and the luminance is increased as RF power is increased. It was also found that the luminance per unit RF power is high when the argon pressure is low and when the RF power is in the range of 30 [W]${\sim}$40 [W].

To clarify the relations of optical properties to the main factors responsible for the loss and damage of luminous efficacy, a 20 min turn-on/turn-off test for 2,000 h for a ceramic metal halide lamp is conducted. The corrosion rates of the arc tube wall and electrode are estimated based on thermal stress. Wall blackening is attributed to the tungsten being transported from the hot electrode tips to the relatively cold arc tube wall. Furthermore, the grain boundaries of the arc tube are changed by the degradation. Distortion of the electrode is observed, and the ignition and the driving voltage of the load both increase. Finally, the color rendering index and the color coordinates are changed after the degradation. The luminous flux and the intensity of the luminous distribution are decreased significantly.

The not an organization a branch stream the maintenance factor class on a class and the roadway type for roadway lighting design, the facted an insufficiency maintenance factor to apply our the country conditions. The consideration of maintenance factors is not being fully applied for roadway lighting design in Korea. This paper consider optical characteristics and maintenance factors as well as LID of Luminaires in designing roadway lighting. Consideration of maintenance factors that are neme specified according to LDD(Luminaire Dirt Depreciation), LLD(Lamp Lumen Depreciation), AADT(Average Annual Daily Traffic) based on IESNA regulation. The analyzed optical characteristics are applied for stagger and cross roadway types with maintenance factors in the range of 0.51$\sim$1.00 and equipment factor of 0.9.

Tatan is a symbol of kinship and belonging in Scotland and a badge of identity recognized all over the world. Alongside the powerful historical and national resonance to Tartan for Scots it has been borrowed repeatedly by fashion. The pattern compositionof Tartan check is formed as a typical cross stripes that vertical line and hrizontal line meets rectangulary. And its color is much various and rich than other check pattern. So its magnificient spec-tacle that various all kinds of colors is dyed in cloth is second to name. Today we are as likely to meet tartan in a couturier dress as in a kilt or plaid. Tartan is distinctive in colour style and de-sign. It conveys personality ceremony and drama. All these aspects of its character have contributed to tartan being one of the best-known and best-loved fabrics in the world. In other parts of Europe traditional checked patterns declined and disappeared but in Scotland tartan survived strongly jist as the bagpipes also European flourished Due to geographical and cultural circumstances Scots were able to develop and enhance tartan and its remarkable individuality ensured its sur-vival in spite of adverse political and economic pressures. Tartan has been adopted as the national dress of all Scots. Lowland and High-land providing a powerful form of national cultural and personal identity. Whether tra-ditional or a recent creation whether tra-ditional or a recent creation whether a symbol of nationality or a substitute for nationhood tartan is no mean achievement.
