The effects of light on the growth and ginsenosides production were examined in the hairy roots of Panax ginsen C.A. Meyer induced by Agrobacterium rhizogines A4. The 9rowth of ginseng hairy roots in 1/2MS liquid medium was significantly decreased with an increment of light intensity (1,000~7,000 lux). The growth of hairy roots under 7,000 lux condition was decreased at 17% compared to the dark condition. The production of 7 ginsenosides in hairy root was very high in 3,500 lux condition. The production of ginsenoside-Rg, and Rf increased 3.3 and, 2.4 times respectively as compared to dark condition. The growth of hairy roots was inhibited by blue light, while ginsenosides production was increased. The sucrose demands of hairy roots was examined in light condition(3,500 lux). The growth of hairy roots in 1/2MS liquid medium with various sucrose concentrations(1~4%) was high in IVp sucrose, while ginsenosides production was high in 3% sucrose condition. The growth and ginsenosides production were high when hairy roots were cultured in dark condition for 1 week and then transferred to light condition(3,500 lux) for 4 weeks. It is suggested that ginsenosides production could be accelerated by light intensity of specific wavelength in cultures of ginseng hairy roots.

The objectives of this study were to investigate the differences of image evaluation of baseball uniform by uniform design and perceiver's gender. and to examine how baseball uniform preferences vary according to perceiver's gender. Stimuli consisted of 12 color photographs of a male model wearing a baseball uniforms which were manipulated according to the color of shorts and pants. A semantic differential scale of 23 items were used to evaluate the image of the stimuli. Subjects were 288 males and females. Five dimensions derived to account for the image of baseball uniform. These were manly, ability, activity, preference, and visibility. Wearing of red shirts had a positive effect on the evaluation of ability, activity, and visibility. Dark blue shirts had a positive effect on the evaluation of preference. Grey uniforms had negative effects on the evaluation of ability, activity, and visibility. Men liked white uniforms and vertical stripes uniforms of black and white more than dud women. Women talked dark blue shirts more than did men.

Thc effect of light and phylohormonc on the belalaln synthesis was tested using the suspension culture of a rod(bclalaln produulng) cell line from Phytolacca esculenta V. Houtte. Betalain synthesis of rod-cell 1ine was strongly dependent on the irradiation of blue light, but induced by hormone, IAA and/or kinetin, in dark conditions. In a light condition, however, 2 mg/l of IAA increased the betalain content about 30% (per gram fresh weight), whereas more than 0.5mg/l of kinetin remarkably decreased. The hairy root derived from the same plant was also observed for the blue light-dependent pigmentation in the root-tips. When the hairy root grown in dark was transferred to the light condition, the accumulation of betalain was initiated after 12hours. Such pigmentation was completely inhabited by addition of a protein synthesis inhibitor.

The purpose of this research was to investigate the effects of used color and tone on harmony perception by applying contrast coloration of shirt and necktie. This experiment designed by shirt color(red, blue, purple, green), tie color(green or blue tie with red shirt, yellow or red tie with blue shirt, yellow or green tie with purple shirt, purple or red tie with green shirt), shirt tone(vivid, light, dull, dark), tie tone(vivid, light, dull, dark), and perceiver gender(a male, a female). The experimental materials developed for this study were a set of stimulus and response scales, we harmonized those colors of shirts and neckties contrast, then made shirt and necktie tone differently. The subjects of this research were 640 male and 640 female college students. The data was analyzed by using SPS program. Shirt color, tie color, shirt tone, tie tone, perceiver gender influenced on harmony perception independently. Shirt color and tie color, shirt color and shirt tone, shirt color and perceiver gender, tie color and tie tone, tie color and perceiver gender, shirt tone and tie tone influenced on the harmony perception by interaction.

The purpose of this study is to investigate the aesthetic characteristics of check fashion of the 20th century and to analyze the formativeness for them shown in recent collections. The results of this study are as follows; 1) Before the First World War, check patterns were used for S silhouette dresses and hobble dresses. During the two wars, they were used for garçonne style dresses and military suits. Check patterns were used for mini style in the 1960s, uni-sex style in the 1970s, and power suits in the 1980s. Especially after the 1980s, check patterns have followed the fashion trend of each season and appeared in retro styles. Consequently, the aesthetic characteristics of check dresses of the 20th century are traditionality, ornamentation and eclecticism. 2) Traditionality of check fashion shown in recent collections was implied in the classic styles like suits with its grey glen check, avant-garde styles like boxy coat with its dark blue tartan check, and so forth. Ornamentation was shown in the modern styles like jackets decorated with block check colored white and black, casual styles like bomber jackets with hound tooth check colored white and black, and so forth. Eclecticism was reflected in the romantic styles like one-piece dresses with hound tooth check colored white and light blue, elegant styles like low-cut dress with its dark blue window pane check, ethnic styles like long cape with gingham check colored white and black, and so forth.

자리공 모상근에서 광처리에 따른 항산화효소의 활성을 조사하였다. Catalasa superoxide dismutasae, ascorbate oxidase (AO)의 활성은 광도가 2,000 lx까지 증가할수록 감소하였으며, 특히 AO활성은 2,000 lx에서 암상태보다 92% 감소하였다. Glutathione reductase, glutathione peroxidase (GPO), ascorbate peroxidase 그리고 peroxidase의 활성도는 500 lx까지는 광도가 높아질수록 증가하였으나 그 이상의 높은 광도에서는 현저하게 감소하였다. GPO의 활성은 AO처럼 2,000 lx에서 암상태보다 85%감소하였다. 광파장에 따른 항산화효소의 활성은 청색광의 파장에서 가장 많이 억제되었으며, AO의 활성은 25%까지 감소하였다. 청색광 파장의 광도에 따른 항산화효소의 활성도는 30 lx까지는 증가하다가 200 lx에서는 암상태보다 21-71%까지 감소하는 경향을 나타내었다. AO의 활성은 청색 파장의 광도(300-200 lx)가 증가할수록 급격히 감소하여 200 lx에서는 70%까지 억제되었다. 자리공 모상근의 항산화효소 활성은 청색광 파장의 높은 광도에서 주로 생성된 유해산소 의하여 억제되고 있음을 확인하였다. 광상태하에서 모상근의 생장과 betalain 합성을 향상시키기 위해서는 모상근에서 생성되는 산화제의 효율적인 제거가 요구됨이 시사되었다.

This study suggested comprehensive structural characterization methods for the commercial blue light emitting diodes(LEDs). By using the Z-contrast intensity profile of Cs-corrected high-angle annular dark field scanning transmission electron microscope(HAADF-STEM) images from a commercial lateral GaN-based blue light emitting diode, we obtained important structural information on the epilayer structure of the LED, which would have been difficult to obtain by conventional analysis. This method was simple but very powerful to obtain structural and chemical information on epi-structures in a nanometer-scale resolution. One of the examples was that we could determine whether the barrier in the multi-quantum well(MQW) was GaN or InGaN. Plan-view TEM observations were performed from the commercial blue LED to characterize the threading dislocations(TDs) and the related V-pit defects. Each TD observed in the region with the total LED epilayer structure including the MQW showed V-pit defects for almost of TDs independent of the TD types: edge-, screw-, mixed TDs. The total TD density from the region with the total LED epilayer structure including the MQW was about $3.6{\times}10^8cm^{-2}$ with a relative ratio of Edge- : Screw- :Mixed-TD portion as 80%: 7%: 13%. However, in the mesa-etched region without the MQW total TD density was about $2.5{\times}10^8cm^{-2}$ with a relative ratio of Edge- : Screw- :Mixed-TD portion of 86%: 5%: 9 %. The higher TD density in the total LED epilayer structure implied new generation of TDs mostly from the MQW region.

The purpose of this study is to survey the color preference of mothers for the clothing of their children whose clothing is usually chosen by their mothers. The survey was performed by showing 60 color samples to provide the useful data for the fashion color planning. The result of this study shows that the prefe-rences in hue and tone are different mainly by season. The most preferred colors are yellow for boys and pink for girls in spring white in summer-beige in fall and black in winter. The most preferred tones for boys are pale in spring and summer dull in fall and dark in winter For girls light tone is most preferred in spring and pale in summer bright in fall and dark in winter Analysis of tone preferences in 6 colors shows that bright and clear are commonly preferred tones for children's clothing. Pale light vivid tones of yellow green and blue are preferred for girls and boys. Dark purple is preferred in fall and winter while pale tone is preferred in spring and summer. Red is preferred for girls especially in pale bright vivid tones while dark grayish and deep tones are preferred for boys in fall and winter.
