It was applied by making the models such as the prior learning (e-learning), modeling by manual, learner's practice, 1:1 teaching coaching, self evaluation, coaching behavior assessment(primary, secondary), and self-directed practice. First, the cognitive practice education through the prior learning is very essential in the practice of floral design. Second, the practice class of floral design is a class where the professor generally set an example first, and the learners followed. Third, this study was to prepare the checklist, reflect it through the self evaluation, and prepare the evaluation form in accordance with the element, principle, and technical parts of floral design about the finished works. Fourth, contrary to the existing class completing within the class hour, the practice class is a process of trying to do self-directed practice, returning to home. Fifth, this study was to evaluate the works the learner made once again through the sketching and photographing by placing the work process of portfolio at the last step. To conclude, this study has found that such series of process through six steps on the practice form by the learner only would be excellent teaching learning model to improving the basic capacity of floral design. Accordingly, the development of teaching materials related to this and adaptation in the field in the future is considered as it will be very helpful to the learners' self-directed learning.

현대 디자인 분야에는 건축이나 제품, 의복 등에까지 투명성이 디자인의 매우 중요한 요소로 활용되고 있다. 아름다우면서도 기능성과 견고함을 지닌 투명한 재료들이 과학기술의 발달에 힘입어 속속 개발되고 있으며, 또한 투명성 디자인은 현대 디자인의 트랜드인 즐거움과 유희 등을 표현하는 감성 트랜드와 잘 부합되기 때문이다. 본 연구는 이러한 시대의 흐름에 발맞추어 사용자들에게 재미와 즐거움의 가치를 감각적인 부분과 통합할 수 있는 디자인 개발에 목적을 두고, 20세기 후반부터 트랜드의 커다란 부분을 차지하고 있는 투명성을 좀 더 재미있고 여성스러운 감성을 자극할 수 있는 새로운 재해석의 방향을 찾아 패션 디자인을 제안하고자 한다.

The study is aimed to obtain the basic data for developing new variations of wild spring orchid. The results was investigated the capsules' formational characteristics and the germination ratio after having been self-pollinated by dividing the flowering period into the 5 stages into budding time, semi-flowering, full-flowering, 10 days after flowering, and 20 days after flowering. The fruit setting ratio was the highest as 100% in the plant which had been pollinated 20 days after the flowering, while the weight of the capsule was heaviest in the orchid which had been pollinated in semi-flowering period. As the result of investigating the germination ratio by dividing the period into 5 stages, it was the highest in the plant which had been pollinated during the semi-flowering period, and in the result of investigating the germination ratio by dividing the seeds harvesting days into the 3 stages, such as, 150 days, 165 days and 180 days after the pollination, it was highest as 5% in the orchid whose seeds had been harvested 150 days after the pollination. In the result of examining the germination ratio of the seeds treated with NaOCl, the those treated with 2% of NaOCl showed the highest as 67% in the germination ratio.

Standard carnations are widely used in flower design as a mass flower, but there is a limit to the use in that it can not be used in various colors in addition to its own color. The purpose of this study was to investigate how does artificial dyes affect vase life, using standard carnations, and to improve utilization of dyeing carnations in floral design. Using standard carnation 'White Liberty', dyeing experiment was performed according to four kinds of chemicals for each of six dyes. Six different dyes from Koch(Robert Koch industries Inc., USA) as follows light blue(2386), lime green(2315), christmas red(2506), lavender(2200), orange fire(2268) and black(2012) have been used and four different chemicals as follows distilled water, 4% ethanol, 3% sucrose and 100mg·L^-1 citric acid have been used with the cut Dianthus caryophyllus 'White Liberty'. As a result, six different dyes showed fast and excellent dyeing with 3% sucrose and 100mg·L^-1 citric acid treatment. But vase life in other dyes except black and lavender tended to be similar to control(7 days).

This study was conducted to provide exportation strategy by surveying on preference of Japanese consumers on cut chrysanthemum exported. The survey was conducted two times by a local survey company in Japan, and the surveys were conducted largely on chrysanthemums for casual flowers and the altar. After departmentalizing Japanese consumers per groups the result were analyzed through conjoint and cluster methods, flower colors and shape were used relatively higher rate for selection criteria of flowers in every group in the case of casual flowers. Group 1 comprised of 60 year-old housewives who reside in a small city with high school diploma and annual income less than 300 million yen, and group 2 of 40 year-old housewives who are small city residents with high school diplomas and annual income of 300 million yen show higher rate of use in flower shape than colors. Another group 3 whose members are 50 year-old housewives, small city residents with high school diplomas and annual income of 600 million yen showed higher rate of use colors than the shape for selection criteria of flowers. The consumption characteristics according to the ages of the consumers showed a pronounced tendency. The 40-50 year-old housewives preferred single flowers packed with other flowers, and the 60 year-old housewives double flowers packed with only chrysanthemums. In flower color, the 50-60 year-old housewives preferred white and yellow flowers, and the 40 year-old housewives pink and yellow flowers. Therefore, there are needs for development strategy of new products considering the consumption characteristics of flower shape and color according to the ages of consumer. After analyzing the chrysanthemums for altar by departmentalization of Japanese consumers, every group showed relative higher rate of use for flower shape for selection criteria of flowers. According to the analysis on the consumption characteristics, group 1 which is comprised of 30-40 year-old housewives who reside in small city with high school diplomas and income less than 300 million yen, and the group 2 of 20 year-old housewives who reside in small city with college diplomas and annual income less than 300 million yen. They are very sensitive to the price of the products while the group 3 of 50 year-old housewives who reside in small city with high school diplomas and annual income less than 300 million yen are insensitive to the price. The 30-50 year-old housewives preferred white and pink flowers, and the 20 year-old housewives yellow and pink flowers. In flower shape, the 50 year-old housewives preferred anemone shape, the 30-40 year-old housewives double shape, and the 20 year-old housewives pompon shapes. Therefore, the white, double flowers for the 30-40 year-old housewives and the yellow, pompon flowers for the 20 year-old housewives are needed to be created at the lowest cost, while the white, anemone flowers are needed to created at higher cost with high quality. In light of these results, it is considered that we should understand the types of purchasing products through consumption characteristics of Japanese consumers. Also we should plan, create market-oriented and consumer-oriented products, and should export them in order to expand more exportation.

In roll forming process, a sheet metal is continuously progressively formed into a product with required cross-section and longitudinal shape, such as a circular tube with required diameter, wall-thickness and straightness, by passing through a series of forming rolls in arranged in tandem. In recent years, that process is often applied to the bumper rail in the automotive industries. In this study, a optimal front side member manufacturing technology, model deign and proper roll-pass sequences can be suggested by forming number of roll-pass and bending angle. And also effects of the process parameters on the final shape formed by roll forming defects were evaluated.

In roll forming process, a sheet metal is continuously progressively formed into a product with required cross-section and longitudinal shape, such as a circular tube with required diameter, wall-thickness and straightness, by passing through a series of forming rolls in arranged in tandem. Tn this process, each pair of forming rolls installed in a forming machine play a particular role in making up the required cross-section and longitudinal shape of the product. In recent years, that process is often applied to the bumper rail in the automotive industries. In this study, a optimal Front Bumper Beam manufacturing technology, model deign and proper roll-pass sequences can be suggested by forming number of roll-pass and bending angle. And also effects of the process parameters on the final shape formed by roll forming defects were evaluated.
