To examine the availability of onggi (earthenware) as a floral vase, we compared the vase life of cut gerberas (Gerbera jamesonii) with generally used vases made of glass and porcelain. After holding cut gerbera 'Honeymoon' and 'Golden Time' in vases made of glass, porcelain, and onggi containing holding solution (tap water or preservative solution), vase life, fresh weight, and water uptake of cut flowers, and total number of microbes in holding solution were collected. In onggi vase, vase life of both the cultivars was longer than the other vases and floral preservative prolonged vase life compared with tap water. Cut gerberas applied with preservative solution in onggi vase maintained their ornamental value for more than 14 days. Cumulative water uptake by cut gerberas was greatest in onggi vase, where 'Honeymoon' and 'Golden Time' absorbed water by 19.2 and 15.8 mL, respectively, for 10 days. Fresh weight of cut flowers in onggi vase was greater than those of the others, and the preservative solution delayed the reduction of fresh weight compared with tap water. Especially, onggi vase with preservative solution maintained 89% of the initial fresh weight at the 8th day of the treatments due to smooth water uptake with comparison with 71% in porcelain. Total number of microbes in the holding solution was smallest in onggi vase. At the 8th day, microbes number in onggi vase was 435 cfu/mL, that was 20-30% level of those of glass and porcelain vases. In conclusion, onggi vase inhibited microbial proliferation in holding solution, maintained water uptake by cut flower, and delayed bending of flower stalks due to vascular blockage, and then prolonged vase life in gerbera. Therefore, onggi with numerous micropores will be a good material for flower vase and preservative solution can improve its function.

The objective of this study was to determine the effect of calcium concentrations in fertilizer solution on growth and cut flower quality of chrysanthemum 'Biarritz' To achieve this, deficiency symptom and growth characteristics as influenced by controlled Ca concentrations in fertilizer solution were investigated. The analysis of plant tissue and soil solution of root media were also conducted to secure optimum concentration for plant growth. Calcium deficiency developed on the very youngest leaves and the young leaves developed 'cupped' shape as they expand. The cut flower length of 0, 3.0 and 6.0 mM treatments were 105.8, 106.5, and 107.3cm, respectively. Elevated Ca concentration within the range from 0 to 6.0mM in fertilizer solution increased cut flower weight. The cut flower weight of control and 6.0mM treatment were 51.6 and 59.4 g, respectively. The tissue Ca content of 6.0mM treatment in which crops showed the highest growth among treatments was $3.09\%$ based on the dry weight of the youngest fully expanded leaves. From the results, it seems necessary to maintaining tissue Ca content higher than $2.8\%$. Soil Ca concentrations increased as K concentrations in fertilizer solution were elevated. Ca concentration in 0.0, 1.5, 3.0, 4.5 and 6.0mM treatments were 5.0, 7.4, 12.1, 16.5 and $28.2mg{\cdot}L^{-1}$, respectively, at harvesting stage. It is suggested that Ca concentration higher than $25.4mg{\cdot}L^{-1}$ in soil solution of root media is required to maintain normal growth.

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.

Buddhist temples and halls signify paradise on earth. Buddhist sutras refer to paradise as a place where flowers fall down like snow, fragrance and music fill the air, flowers blossom and butterflies fly. The Kkot Mun of Buddhist temples are an essential part of the creation of this paradise and are ornamented with elaborate sculptures of flowers and animals. The ornamentation of the Kkot Mun is truly admirable for its artistry and beauty. Although the Kkot Mun is an element of Korean traditional Buddhist architecture, it could also be applied to costume work. I thought the characteristic elements of the Kkot Mun for the costume work were the flower, the lattice and the transparent effect that was made with the lattice and Dagjongee. I used the technique of strap cutting, strap twisting and cut-out for the lattice of Kkot Mun and flower making, knitting, cut-out and quilting for the flower of Kkot Mun. I represented the transparent effect of Kkot Mun with the lapped materials. I selected six remarkable Kkot Mun of Korean temples, revised shapes of these and made six costume works. These six costume works would be the suggestion of costume design if an element of Korean traditional architecture was applied to modern costume making.
