Purpose of this study is to explore: 1) the difference in color sensibility evaluation, color attractiveness, and attitude toward the product, 2) the difference in the effect of color sensibility evaluation on color attractiveness, and 3) the difference in the effect of color sensibility evaluation on attitude toward the product between the identical clothing product presented in on-line and off-line settings. Experimental method was applied with 230 male and female university students using stimuli of an on-line site as well as an off-line window display presenting the same white t-shirts. Color sensibility factors of white t-shirt were hedonic, stimulating, active, and spatial senses. These color sensibility factors of the clothing product affected product color attractiveness as well as attitude toward the product. Although there were not differences in color sensibility evaluation, product attractiveness, and attitude toward the product between items presented in on-line and off-line settings, difference was found in the effect of color sensibility on the color attractiveness and attitude toward the product. The effect of color sensibility on color attractiveness and attitude toward the product was stronger in on-line than in off-line setting. Hedonic sense was the most important factor influencing attractiveness of product color and attitude toward the product. In addition, spatial sense affected attractiveness of product color in on-line setting; and stimulating sense impacted attitude toward the product in off-line setting. Based on the results implications were generated.

The Authors have demonstrated high efficiency hybrid white organic light-emitting diodes (HWOLED) for reduced efficiency roll-off and color stability. It was shown that HWOLED fabricated in this study have the maximum luminance of 46 420 cd/$m^2$ at 8 V (turn-on voltage of 2.7 V), external quantum efficiency of 13.18%, power efficiency of 28.75 lm/W at 1 000 cd/$m^2$, and reduced efficiency roll-off of 2.7 times than control white device. The HWOLED also showed the stable color shift with $\Delta$Commission Internationale de I'Eclairage coordinates coordinates of ${\pm}$ (0.00, 0.00) from 100 to 10000 cd/$m^2$.

Greate white sharks, Carcharodon carcharias, are found in almost all the temperate and tropical coastal waters around the world. There have been 19 appearances reported in Korean coastal waters since June 1996 and seven shark attacks have been reported. There are about 400 species of sharks in the world, and 41 species of them have been found in Korean coastal waters. Thirteen of them belong to the Carcharhinidae family, and five of them belong to the Squalidae family. Of these sharks, 15 species of them live off of the East coast, 18 species live off of the West coast, and the other 40 species are distributed around Jeju Island and the South coast. Eleven species of them, including the great white shark, live off of all the coastal waters of Korea.

Future electric lights will be composed of white LEDs (Light Emitting Diodes). Indoor wireless optical communication systems utilizing white LED lights have been studying about it. Generally, plural lights are installed in room. Therefore, their optical path difference must be considered. In this paper, the influence of an optical path difference has been investigated and two approaches against this problem are introduced. One uses OOK-RZ (On-Off Keying, Return-to-Zero) coding and the other uses optical OFDM (Orthogonal Frequency Division Multiplexing). From the results of computer simulations, we have found that these approaches are feasible for the wireless optical communication systems utilizing white LED lights.

감마선 조사기술을 이용하여 계란의 알러지성을 감소시키기 위한 실증 연구의 일환으로 감마선 조사된 난백을 함유한 cake의 물성 학적, 관능적 품질을 평가하였다. 전란에서 난백을 분리한 후 10과 20 kGy의 흡수선량을 받도록 감마선을 조사하였다. 감마선 조사된 난백을 첨가한 white layer cake, poundcake와 sponge cake를 제조하여 시험하였다. 10과 20 kGy로조사한 난백을 첨가하여 제조한 모든 제품에서 경도가 높은 것이 관찰되었다. 저 장 중 감마선 조사된 난백을 함유한 pound cake와 sponge cake의 노화가 지연되어 물성 학적 저 장성 측면에서 더 우수한 것으로 나타났다. 감마선 조사된 난백이 cake의 관능적 품질에 미치는 영향은 제품의 특성에 따라 다르게 나타났고, 모든 처리구에서 방사선 불쾌취(off-odor)가 관찰되어서 제품 제조시 관능적인 품질을 유지하기 위한 적절한 방법이 이용되어야 할 것이다.

Pinellia koreana K-H Tae & J-H Kim is a recently discovered Korea endemic medicinal plant species whose natural habitat is rapidly destroyed by industrial development. Described in this paper are culture conditions for high frequency plant regeneration via bulblet formation from leaf explant cultures of P. koreana. Leaf explants formed white nodular structures and off-white calluses at a frequency of 91.2% when cultured on MS medium supplemented with 2 mg/L BA and 0.5 mg/L NAA. However, the frequency of white nodular structures and off-white calluses formation was slightly decreased with an increasing concentration of NAA up to 4 mg/L, where the frequency reached 31.7%. Most petiole explants did not form white nodular structures and off-white calluses except the combination treatment of 2 mg/L BA and 2 mg/L NAA. Upon transfer onto MS basal medium, over 90% of nodular structures gave rise to numerous bulblets and developed into plantlets. Plantlets regenerated from bulblets were transplanted to potting soil and grown to maturity at a survival rate of over 95% in a growth chamber. Therefore, the in vitro plant regeneration system of P. koreana obtained in this study will be useful for mass propagation and long-term preservation of genetic resources of P. koreana.

거듭 발전해온 여러 분야의 기술들은 공간과 물건들 그리고 우리들의 상호관계에 더욱 더 많은 영향을 주고 있다. 그러나, 그럼에도 불구하고 그 기술들로 이루어진 제품과 서비스를 이용하는 방법에는 한계성을 가지고 있다. 즉 아날로그의 우리의 생활환경과 디지털 정보환경의 존재 적 상이성으로 제품과 그 서비스의 사용성의 소통은 원활하지 못하고 있다. 예를 들어 ON과 OFF는 마치 BLACK과 WHITE처럼 표현되어 우리가 일상적으로 생활하는 아날로그 환경과는 달라 불편함을 느낄 때도 있다. 이 시점에서 디지털 정보환경의 사용성을 아날로그 적인 요소 (HUMAN QUALITY)를 가진 입력장치(INPUT DEVICE)의 개발과 제안은 의미가 있다. 이 연구의 궁극적인 목적은 제품과 그 제품이 가지는 서비스의 가치를 사용성을 중심으로 개선하고 제안하고자 함이다. 예를 들어 제품의 가치를 소통할 수 있는 방법은 그 기능에 접근성을 가진 SWITCH라고 할 수 있는데, 그 디지털 적 행위의 소통성으로 가진 스위치들은 제품의 기능과 서비스를 이해하기에 상당한 한계성을 가진다. 그래서 본 연구는 제품의 특성과 환경에 맞는 아날로그 입력장치를 개발하고 제안하고자한다. 시간, 패턴, 자유, 리듬 등을 ON과 OFF사이에 설정함으로서 존재하지만 볼 수 없었던 제품과 그 서비스의 가치를 찾아 좀더 자연스럽고 따뜻한 HUMAN QUALITY를 가진 제품을 만들고자 함이다. 단순히 ON, OFF가 아닌........

In outdoor visible light communication channels and LED road illumination communications for the intelligent transport systems (ITS), inter symbol interference (ISI) due to multipath propagation prevents high data rate transmission. Indoor wireless optical communication systems utilizing white LED lights and on the road illumination have been studying about it. Generally, plural lights are installed in room and considered to the traffic information system using existing LED traffic lights. Therefore, their optical path difference must be considered. In this paper, the influence of an optical path difference has been investigated and two approaches against this problem are introduced. One uses on-off keying, return-to-zero (OOK-RZ) coding and the other uses optical orthogonal frequency division multiplexing(OFDM).

In this study, we report oscillations of the total intensity of white light loops in the off-limb solar flare observed in 2017-Sep-10 with the SDO/HMI. The total intensity oscillations are correlated with the area of the flaring loop in the plane of the sky. The oscillatory pattern is well fitted by two consecutive damped oscillations. The period and damping time of the first oscillation are 12.9 minutes and 9.9 minutes, respectively. Those of the second oscillation are 11.7 minutes and 15.4 minutes. The excitation of the oscillations coincides with two consecutive type III radio bursts observed in meter range. Assuming the oscillations are magnetoacoustic waves in the flaring loops with the loop lengths ranging from 30 to 90 Mm, the temperature of the white light emitting loops could be in the range from 0.3 MK to 2.6 MK.
