  • This study focused on the properties natural dyeing and natural material and on the development of functional material for well-being in apparel industry. Comus officinalis Siebold et Zuccarini is used as natural dyeing material which had been reported that have curable effect for unbalanced immunity, geriatric diseases like urinary tract system, diabetes, hypertension, arthritis, tinnitus, hyperhidrosis and women's diseases like hypermenorrhea. And this material also has anti-cancer effect so that can restraint cancer cells. 3 kinds tester of cotton, wool and silk are dyed by boiled with each dye (flower, fruits, bark of tree) as first dyeing and dried in the shade. These testers are done by post-mordanting method. Aluminium Potassium(Alk(SO4)2), Cuprie Sulfate($CuSO4{\cdot}5H2O$), Stannous Chloride($SnCl2{\cdot}2H2O$), Ferrous Sulfate($FeCl2{\cdot}4H2O$), Titanium Sulfate 24% aqueous solution(Ti(SO4)2) are used as mordants. Dyeing results of Comus officinalis Siebold et Zuccarini flower and bark are shown as yellow color series. And dyeing result of fruits is pink color series. Silk shows the best dyeing property. As the point of view for dyeing property, Ti, Sn, Fe would be the properchoice for mordant. Following results are extracted in this study. Yellow color is resulted in dyeing with Cornus officinalis flower as non-mordanting condition. Yellowish red color is come from dyeing with Comus officinalis fruit as non-mordanting condition. Grayish yellow tone is resulted in dyeing with bark as non-mordanting condition. Orange tone color with Ti-mordanting, green tone color with Sn-mordanting and gray tone color with Fe-mordanting is resulted respectively. However light-fastness of Comus officinalis(flower, fruit, bark) is very low as 1 or 2 level in non-mordanting condition, Comus officinalis flower dyeing is turned out 3 or 4 level and fruit dyeing is 4 or 5 level, bark dyeing is 2 or 3 level with Ti-mordanting respectively. Eventually Comus officinalis fruit has the best light-colorfastness property among all of dyes. dry cleaning colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, perspiration-colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, With these results, this study could conclude that dye-ability, colorfastness problem is getting better after mordanting process and practical usage would be possible.

  • This study was carried out to obtain the basic information on the development of flower bud and to clarify the characteristics of flower organ and flowering in Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolium). The formation of flower bud in the dormancy bud of Korean ginseng was initiated about the middle of June and completed late in September. The ovary, style and anther of Panax ginseng, violet-stem and yellow-berry variants, were formed earlier than those of Panax quinquefolium. Panax ginseng, therefore, flowered earlier by one month in comparison with Panax quinquefolium. As for the effect of temperature on the flowering of ginseng, both species, Panax ginseng and Panax quinquefolium, grown at 20 $^{\circ}C$ flowered earlier than those at 15 $^{\circ}C$ and field conditions, but did not flower at 30 $^{\circ}C$. Seed characters were better in Panax ginseng than in Panax quinquefolium and the amount of seeds showed the highly significant positive correlation coefficient with peduncle length in both Panax ginseng and Panax quinquefolium.

  • This study was conducted to examine the characteristics of flowering and fruiting in Nelumbo pentapetala 'Yellow Bird'. Lotus rhizomes were planted in pot (70 cm in length and 71 cm in width) on April 18, 2008, and grown under rain shelter condition at a private farm in Muan-gun, Jeonnam. Ninety percent of the lotus plants were bloomed as two flowers per a plant, and the others were one flower. The first flowers were bloomed in the middle or late July, and the second flowers in the early August. Flower stalks were formed between eighth and tenth internodes in the main rhizome. Nelumbo pentapetala 'Yellow Bird' had light yellow flowers, 12 cm in length and 13 cm in width. Lotus plants of 21.4% were not bloomed, resulting from the insufficient securing of internodes in the main rhizome and the blind. We, therefore, concluded that Nelumbo pentapetala 'Yellow Bird' as a ornamental plant should be grown up to 8 in the node number of main rhizome until mid-July.

  • The purpose of this study was to determine the effects of flower decorations on job stress and stress copying style of police officers. Flower decorations were done in the form of "one-table one-flower", in which flowers were placed on each desk in the office space. By analyzing color psychology, we first identified the symbolism of color, and selected the cut flowers in the same color. We selected six types of flowers in six colors: red, orange, yellow, green, blue and purple. Each Monday morning, the flower decorations were delivered to the police station. We selected 50 subjects who wanted to keep flowers on their desks every week as the experimental group and 44 subjects who only wanted to participated in the assessment as the control group. Before and after the program, we examined the mean difference between the control group and experimental group. After six sessions of the program, there was a significant difference in job stress (p < .001) and stress copying style (p = .049) of the experimental group compared to the control group. Therefore, this study proved that having flower decorations in an office space is effective for the psychological stability of police officers that are highly stressed, due to sensory stimulations from the colors and scents of flowers as well as mutual interaction as they take care of the flowers.

  • A new gerbera variety "Pink Swan" was released by the National Horticultural Research Institute (NHRI) in 2007. A cross was made between "Royal" with orange and single and 'Himalaya' with white and semi-double in 2004. After investigation of the characteristics for 4 years (from 2004 to 2007), it was selected specially for the use of cut-flower. "Pink Swan" is a vigorous medium-sized cultivar with pink (RHS R48D), yellow green center and semi-double. The average flower diameter is 10.6 cm. And inner ray floret and disc diameter is 5.99cm and 1.83cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height. We believe that "Pink Swan" has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.
