Regarding the facts that fat, which is easily oxidized, is one of the major responsible factors affecting the quality of aroma, and polyphenol compounds including chlorogenic acid (CGA) contribute the anti-oxidative activities to coffee, we investigated fat oxidation, conversion of CGA, and changes of anti-oxidative activities according to the degree of roasting and storage of 60 days. We found that the amount of extractable fat by diethyl ether is increased as the coffee beans are roasted longer. Furthermore, the acidity values of the fat are increased from $8.91{\pm}0.16$ to $17.81{\pm}0.11$, and $10.37{\pm}0.27$ to $17.93{\pm}0.09$ in the medium and dark roasted coffee beans, respectively, while it is increased from $4.47{\pm}0.11$ to $11.89{\pm}0.18$ in the green coffee bean after 60 days. The CGA contents in the coffee beans were decreased from $310{\pm}8.2$ to $282{\pm}11.2$, then to $58{\pm}0.0mg$ in 10 gr of the green, medium and dark beans, respectively, and were not changed significantly during the storage period. However, the anti-oxidative activities measured by 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid radical scavenging assays were not significantly different among the green, medium, and dark coffee beans during the storage period. Furthermore, antioxidant reactive element-luciferase assay showed that biological anti-oxidative activities were increased as coffee beans were more roasted and stored longer. As the total polyphenolic contents in the beans were significantly decreased by roasting, the results suggests that other molecules, such as, Maillard reaction products might play substantial role in anti-oxidative activity and influence cup quality of coffee.

Epidermal growth factor is a single-chain polypeptide consisting of 53 amino acids and has a potent mitogenic activity that stimulates proliferation of various normal and neoplastic cells through the interaction with its specific receptor(epidermal growth factor receptor, EGFR). Pleomorphic adenoma is the most common salivary benign tumor and histologically, it contains the epithelial cell, the myo-epithelial cell and mesenchymal ingredient, which is various aspect. Adenoid cystic carcinoma is an infiltrative malignant salivary gland tumor with three different histological patterns: cribriform, tubular or solid. The tumor cell structure composed of modified myoepithelial cell, and basaloid cell. In this study, we used an immunohistochemical technique to investigate the expression of EGF in 6 specimens of adenoid cystic carcinoma and 10 specimens of pleomorphic adenoma taken from patients treated at Dept. of Oral and Maxillofacial Surgery, Dankook University. The results were as follows. 1. In pleomorphic adenoma, ductal structure and scattered spindle cells in hyalinized stroma, disclosing myxoid stroma and hyalin, cartilage formation were observed. Immunohistologically, weak EGF expression in ductal structure and negative in stromal area were observed. 2. Cribriform type of adenoid cystic carcinoma showed numerous pseudocyst surrounded by dark small neoplastic cells in the back-ground of fibrous connective tissue and moderate EGF expression of dark cells adjacent to pseudo lumen in cribriform pattern, while weak expression in other most cells. 3. Tubular type of adenoid cystic carcinoma showed numerous ductal pattern surrounded by two layered neoplastic cells in the back-ground of fibrous connective tissue and strong EGF expression in luminal cells of ductal structure, while weak expression in outer cells. From the results obtained, we suggest that EGF is mainly biosynthesized in cells forming duct like structures of tubulo-ductal type or cribriform adenoid cystic carcinoma and it may play a role, as a cell mitogen in adenoid cystic carcinoma growth.

In order to investigate the effect of phytochromes on the regulation of ethylene biosynthesis, we measured the ethylene production and the activities of enzymes involved in ethylene biosynthesis using phytochrome mutants such as $phyA$, $phyB$, and $phyAB$ of Arabidopsis. The ethylene production was decreased in mutants grown in white light. In particular, double mutants showed a 37% decrease compared to the wild type in ethylene production. When Arabidopsis roots were grown in the dark, mutants did not show a decrease in ethylene production; however, production was significantly decreased in the double mutant grown in red light. Only $phyB$ did not show the decrease in the ethylene production in far-red light. Unlike the ACO activities, the ACS activities of mutants showed the same pattern as the ethylene production under several light conditions. The results of ACS activities confirmed the expression of the ACS gene by RT-PCR analysis. The decrease of ethylene production in mutants was due to the lower activity of ACC synthase, which converts the S-adenosyl-L-methionine (AdoMet) to 1-aminocyclopropane-1-carboxylic acid (ACC), the precursor of ethylene. These results suggested that both phytochrome A and B play an important role in the regulation of ethylene biosynthesis in Arabidopsis roots in the conversion step of AdoMet to ACC, which is regulated by ACS.

Paying attention to the fact that Korean traditional ink and color paintings are different in their use of colors this paper was intended to demonstrate outcomes from the difference in their painting style through specific paintings and thereby categorizing a broad range of oriental paintings into 4 types(Indian ink light color, middle color, deep color, present color) in accordance with the method of using colors, suggest directions that oriental color paintings should move toward in the future in the diversity of modem Paintings. Due to the characteristics of materials, oriental ink paintings, in style, are light in color within lines, which in return makes colors confined to a complimentary role in an overall picture, not having their unique color identity Nevertheless, there are some paintings that use dark colors, which is called moderate saturation. For such dark-color based paintings, colors play a key role, together with the characteristics of materials of color painting, as colors are used to express the most part of a picture. This study, thus, discusses the difference in the use of color depending on style on one hand, and examined the diversity of modem color paintings through specific works on the other hand, since a number of color paintings similar to western Painting in style have been created today. In such diversity, works that are being currently created should contribute to taking over the tradition and further develop oriental colors with modem aesthetic sensitivity. This paper is aimed to help to do harmonious works with traditional and modern paintings by studying and classifying varieties of colors

Seed dormancy behavior of weed seeds is a critical determinant of their survival rates in a given cropping system as it helps the weeds to evade herbicides and other weeding practices. We investigated the effects of red light, alternating temperature, stratification duration and different doses of nitrogen containing compounds alone or in combination with red light on breaking seed dormancy of Chenopodium album L. The application of red light(80 ${\mu}mols^{-1}m^{-2}$) significantly increased seed germination of C. album in all treatments. Germination rates of 12 h incubated seeds were highest under 20 min of red light irradiation than 1 min, 5 min and 10 min treated seeds. Germination rate was significantly higher at alternating temperatures of $25^{\circ}C\;and\;5^{\circ}C$ for 12 h each with an irradiation of red light(80 ${\mu}mols^{-1}m^{-2}$) for 10 min than other treatments. Stratification period of 15 days significantly stimulated germination percentage of seeds incubated in dark, although 5 days of stratification along with red light application for 10 minutes exhibit similar effects on seeds. Seed germination was also enhanced by nitrogen containing compounds like $NaNO_2,\;KNO_3,\;NH_4Cl\;and\;NH_4NO_3$. We observed that seed germination increased significantly with 25 mM $KNO_3$ and 10 mM $NH_4NO_3$ in dark condition, while $NaNO_2$ and $NH_4Cl$ enhanced seed germination under red light irradiation. It was concluded that red light alone or synergized with alternating temperatures, stratification and nitrogen compounds, especially nitrite and ammonium enhanced seed germination of C. album. Thus, the red light can play a vital role in present and future weed management strategies.

With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

Subject : The application of eight extra Meridians theory to birth physiology of Korean Medicine. Objective : This study suggests physiological theories in child birth in Korean Medicine. Method : First, the application of eight extra Meridians and extraordinary organs theories to physiology, pathology, pregnancy, postnatal period of women were examined based on major publications and theories of some historical characters. This work provided clues for application of eight extra Meridians theory to birth physiology. Second, the progressing birth physiology of modern medicine based on the importance of the brain function was examined, with which the application of eight extra Meridians and extraordinary organs theories to the birth process showed close relationship. Conclusion : The following conclusions could be drawn. In traditional publications of Korean Medicine, the contents explaining birth physiology with eight extra Meridians theory were scarce, mainly due to the doctor's perception of birth as part of the natural female physiology along with menstruation and pregnancy. However, the contents explaining menstruation, pregnancy, postnatal physiology and pathology through eight extra Meridians theory could be found in classical texts such as Neijing, Jebyeong-wonhuron, Imjeunginameuian. Therefore, it is reasonable to apply the eight extra Meridians theory to the birth process as well. Modern medicine's understanding that pituitary and hypothalamus hormones are in play on womb in the birth process, such as Oxytocin, is in continuous progress. Moreover, the environmental condition that has been traditionally known ideal to the birth process in both the East and West-dark, warm, quiet and secluded-is being confirmed in modern research. The application of eight extra Meridians theory to birth physiology can help to explain these modern information, and thus make them more acceptable.

Features of the Occult Culture is preferred that powers, demons, magic, magical, unreal etc. Currently Occultism is getting a lot of attention to the public in the society, culture, arts and the play. Fashion in the period that includes all circumstances is a field. Thus, the current Occultism and modern fashion will also be related. Objective of the study is to figure out the form and meaning of Occultism in Contemporary Fashion. An example of the best of contemporary trends is the mass media, For this reason, Occultism symptoms range of case studies mess media(television programs and film). Research on contemporary fashion range was used 2000-2013 fashion collection extracted from the data. Represented in the mess media features of occultism is 'Witchcraft and Sorcery' and 'Death and Horror'. They are story of wizard exorcism and unnatural horror. In the 21st century, modern people are enjoying occultism, and occultism is the one of the entertainment. Expressed in contemporary fashion features of occultism is 'Super-human organism', that is out of the human body, ignoring body shape and type of transformed organism. Second distinction is 'Ghost', they are something like the dark and dismal, shape of ghosts and look pale. Third distinction is 'Neo-Macabre', it is the shape of the skeleton. Skeleton symbolizing the end of life, skeleton to express Occultism has emerged as the most representative motifs in the 21st century fashion. Occultism expressed in fashion is a gothic fantasy, because the fashion can be expressed. In addition, people in modern society wants to be against the norms and taboos. The trend Occult-culture is a symbol of the public's desires and needs.

The expression patterns of cyclin genes, which play a crucial role on cell cycle control, were analyzed with rice calli and leaf blades from seedlings. When callus was transferred from media containing the combinations of 2,4-D and kinetin under the dark conditions to medium supplemented with cytokinin-only on 7 days after the cultures, the expression levels of A-, B- and C-type cyclins from callus were increased significantly. Despite the fact that cyclin genes were well expressed on leaf blades rather than other organs in rice seedlings, rice leaf blades grown on the medium containing various combinations and concentrations of cytokinin for 24 hours had no major effect on the expression patterns of cyclins except zeatin. The relation between cytokinin regulation and the expression of cyclins of rice is discussed.
