In the center of our ancestor's culture, there were poetry, calligraphy, and painting. Above all, poetry was the heart of the culture involved in everyday life. The beauty of poetry was not limited to appreciation of the poetry but it influenced calligraphy, painting, seals, music, architecture and even how the ancestors viewed their lives. Categories of poetry(詩品, CP hereafter) is the poetry written to deliberate the style of poems and its influence went beyond the fields of calligraphy and painting. Even now, our architecture reflects the sentimental influences and values of CP. In order to understand the attitude, mind, and the world view of the architects in the past, comprehensive and deep understanding of their philosophy as well as their cultural and social norms is needed. In this paper, CP is used as the means to investigate and develop such understanding of our ancestors' philosophy and culture. This paper also intends to investigate how the seclusive thinking of Neo-Confucianism is reflected in CP and the overall literature. In addition, this paper aims to examine the trace of CP in traditional architecture as well as the relationships and the flow among various styles of CP. This study therefore serves as an important base in understanding the ancestor's philosophy that pursued balance between life and art, reason and emotion, study and practice, and their architectural expression. It is also expected that this study would work as the groundwork to regain our traditional culture identity.

The effect of NO$_3$-N and NH$_4$-N ratio on the growth of Perilla frutescens in deep flow culture was studied in winter season. NO$_3$-N and NH$_4$-N were treated in the ratios of 12 : 0, 9 : 3, 6 : 6(me/ $\ell$ ). The pH of the nutrient solution was increased an NO$_3$-N:NH$_4$-N=12 : 0 treatment, and decreased in the treatments containing NH$_4$-N, greatly in NO$_3$-N : NH$_4$-N = 6 : 6 treatment. The EC was increased regardless of treatments, but more increased in the treatments containing NH$_4$-N. The stem-base circumference, plant height, root weight, shoot weight, and yields of leaves were by far the highest in NO$_3$-N:NH$_4$-N=6 : 6 treatment and the lowest in NO$_3$-N:NH$_4$-N= 12 : 0 treatment. Among the mineral contents of leaves, N, K, Fe and P were higher in the treatments containing NH$_4$-N. Ca, Mg and Mn were higher in NO$_3$-N :NH$_4$-N= 12 : 0 treatment.

The purpose of this research was to develop labor-saving cultural practices of cherry tomatoes in the deep flow technique (DFT) by omitting the process of raising seedling. Three cultivars, ‘Pepe’, ‘Pico’ and ‘Koko’ were propagated by the immediate setting of cuttings(lateral shoots) to the culture bed and by setting seedlings obtained by raising cuttings for 15 days, and grown in the standard and half - strength solution. 1. The immediate setting resulted in higher plants, larger number of leaves and larger leaf area during the early growth stage. And the harvest time was hastened by six days in the direct setting than that in the seedling setting. It was also earlier in ‘Pepe’, but not significant by different between two strengths of nutrient solution. 2. The average fruit weight was affected only by cultivars, but not by the type of cutting and the strength of nutrient solution. The highest yields were obtained from the immediate setting of ‘Pepe’ in other cultivars grown in the nutrient solution of standard strength. 3. Brix degree of treated cherry tomato juice was higher in ‘Pepe’ tomato cultured by immediate setting than others.

Lettuce plants(Lactuca sativa var. capitata L.) were subjected to nitrogen starvation for 18, 14, 11, 7, and 0 days before harvest. The nitrate content of lettuce was decreased greatly by nitrogen starvation and also its fresh weight. The nitrate content of the middle part of leaves was lowest at the treatment of 18 days before harvest. In the inner part it was lowest at the treatment of 11 and 14 days before harvest. The longer the period of nitrogen starvation was, the more were decreased the absorption rates of cations at harvest. During the experiment, the pH was decreased except the treatment of 7 days before harvest. The EC was continuously increased regardless of treatments.

Fashion designs reflect the trend of the times embedded within the cultural structures of eastern and western civilizations as well as the traditional styles. However, the motives in fashion designs fundamentally come from human beings' willingness for creation through deep understand of nature or using symbolism and artificial esthetic appreciation. Mankind has expressed their willingness for creation through speculation not with the attitude of conquering nature but by acknowledging the flow between their lives and nature. The purpose of this paper is to investigate human beings' transcendental and embracing attitude toward the natural environment and the human environment in fashion design. In natural environment factors, sublimity toward nature's marvelous powers and the transcending state of mind within happiness and delight or the extreme fear or unavoidable coerciveness and the consequential daunting feelings and smallness, and sorrow all stimulate the will of mental speculation and cause a transcending sublimity. A sublime state of mind does not exist in a superficial framework of enjoyment. It is rather an act of transcendence and embracement residing in a sublime object and leading man's spirit into a state of philosophical thought. Also, in man-made Environment factors, we found from magnanimity we were ability to see the true nature of an era's culture.

The external qualities of cherry tomato fruits(Lycopersicon esculentum) grown in circulating deep flow hydroponic culture were non - destructively estimated in 1992 under warm climate conditions and evaluated in 1993-1994 under cool season. The fruit size of ‘Minicarol’ was by far the smallest compared to ‘Chelseamini’ and ‘Popo’. There were high correlations between external qualities of fruits-lengthwise growth harmonized with widthwise growth. The volume and/or weight of fruit could be non -destructively estimated by length and width of fruit. Volume=0.071$\times$ (length+width)$^3$＋0.451, Fresh weight=0.072$\times$ (length+width)$^3$＋0.542. These models were accurately evaluated by fruits harvested in 1994.

This study was conducted to select proper substrate and nutrient solution concentration for favorable growth and quality in common thyme (Thymus vulgaris L.). The growth of common thyme was better in deep flow culture (DFT) than in other substrate cultures. As the nutrient solution concentration rose, the ratio of dry matter increased, while the fresh weight and the number of lateral shoots decreased. The contents of total chlorophyll and vitamin C were higher in DFT than others. Ca, K, P were showed high contents in cocopeat, but Mg content was the highest at half-fold concentration in DFT. Common thyme showed low content of nitrate in DFT compared with that in other substrate culture. DFT was the most effective system for pronoting growth and quality of common thyme. The optimal concentration of nutrient solution in common thyme was half-fold(EC=1.2mS/cm) of herbs nutrient solution by European Vegetable R&D Center.

This study was conducted to evaluate the effect of different surfactants on the fertilizer reduction and increase of the mineral nutrients uptake of lettuce (Latuca sativa L. 'Hanbatchungchima') in deep flow technique culture. The measured items from lettuce leaves expanded fully were growth, photosynthetic and transpiration rate, and mineral nutrient content K, Ca and Mg, respectively. The highest growth were observed at $0.3mg{\cdot}L^{-1}$ polyvinyl alcohol (PV4-95) treatment, including lettuce grown in the half strength of nutrient solution. The highest photosynthetic rate, transpiration rate and mineral nutrient content were observed at $0.3mg{\cdot}L^{-1}$ calcium lignosulfate (CLS) treatment. Therefore, high-quality leaf lettuce production could be achieved by apply proper surfactants PVA-95 and CLS, which can cut down the total amount of fertilizer and increase uptake of mineral nutrients.

Purpose : The purpose of this study is to investigate the effects of Simvastain, which is HMG-CoA reductase inhibitor, on proliferation and differentiation of osteoblast. Materials & Methods : Twenty-four cell culture plates containing essential medium were seeded with UMR-106 cell lines, at density of 5 x $10^4$ cells per plate. Each plates were incubated with 5% $CO^2$incubator $37^{\circ}C$. Starting from 2 days after incubation, cell culture medias were replaced with Osteogenesis induction media every 2 days, for 12 days. In some plates, 0.01, 0.1, 1, 10, $100\muM$ of Simvastatin were added with Osteogenesis induction media, and classified as "test group". Those not added with Simvastatin were classified as "control group". Results : 1. When Alrizarin Red staining was observed with naked eye, control group showed normal deep red color, but test group show rapid decrease of red color as Simvastatin concentration increased more than $0.1\muM$. 2, When observed with microscope, compared to control group, amount of osteo matrix stained with Alrizarin Red decreased rapidly in Simvastatin concentration more than $0.1\muM$. 3. In optical density analysis, regarding control group as a basis, mineral deposition decreased rapidly when Simvastatin concentration increased more than $0.1\muM$. 4. In flow cytometry analysis, survival rate of UMR-106 cell showed no changes in both control group and test group. Conclusion : From the above results, we were able to identify that Simvastatin inhibited osteogenesis without effecting survival or cell number of osteoblasts.

Leaf lettuce(Lacaug sativa L.) was cultivated in deep flow culture to investigate growth and yield in relation to different reusing method of nutrient solution after once cultivation. Five different treatments were allocated to the nutrient solutions - Control(total renewal of solution), NSS(nutrient solution supplement), U control, NSAC(nutrient solution analysis and compensation), NSAC and Humus supply(NSAC with supply of Humus). The pH of solution was kept stable below 7.0 during 4 successive culture in NSAC and NSAC and Humus supply. U was sharply declined in NSS as the number of cultivation was increased. Gmwth and yield of NSAC was similar to those of Control because nutrient elements were kept the balance to the better growth, while the lettuce grown in NSS and EC control was shown lower growth rate. In the nutrient solutions, Content of N $O_3$-N and N $H_4$-N were remarkably decreased after the cultivation in all treatments. Ca and Mg were shown to be accumulated in nutrient solution regardless of culture times and treatments. After the first culture in NSAC and Humus supply, total N and P$_2$ $O_{5}$ content in leaves were lower than any other treatments, but Ca content was higher. Those were not significant as following cultures, and no significant difference of K and Mg content were shown among the treatments.
