Although active systemic anaphylaxis and passive cutaneous anaphylaxis have been empolyed to study anaphylactic hypersensitivity, it is difficult and time-consuming to induce these reactions in experimental animals. In recent, Jun et al have found a simple method to induced anaphylactic hypersensitivity such as anaphylactic shock(AS) and cutaneous reaction(CR) using compound48/80. Cortex mori (Morus alba L.), the root bark of mulberry tree has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study was to determine whether the methanol extract of Cortex mori could inhibit the compound 48/80-induced AS and CR. To induce AS, various doses of compound 48/80 (5, 7.5, 10, 15$\mu\textrm{g}$/gm B.W.) were injected intraperitoneally (i.p.) into ICR mice. The animals were pretreated by three injection(i.p.) of Cortex mori before compound 48/80 administration. Peripheral blood was collected from the right ventricle to estimate the level of serum histamine at 15 minutes after the injctin(i.p.) of various concentration of compound48/80. Mortility rate, mean death time and mesenteric mast cell degranulation rate were evaluated over a 72 hour period. To estimate the effect of Cortex mori on compound 48/80-induced cutaneous reaction, various doses of compound 48/80 with or without Cortex mori were injected intradermally(i.d.) into the shaved flank of Sprague-Dawley rats, and the blue cutaneous patchs induced by Evans'blue injection at the compound 48/80 alone and Cortex mori plus compound 48/80 injection sites were observed. As a Parameter of these reactions, the levels of histamine in the supernatant, calcium uptake and intracellular CAMP of RPMC were measured. supernatant, 1)compound 48/80-induced mortility rate, mean death time, mesenteric mast cell degranulation rate, and serum histamine level in ICR mice were significantly inhibited by pretreatment of Cortex mori, 2) cutaneous reaction inducd by compound48/80 was well developed in Sprague-Dawley rat, but Cortex mori inhibited the compound 48/80-induced blue patch formation remarkably, 3) the compound 48/80-induced degranulation, histamine release and calcium uptake of RPMC pretreated with Cortex mori were significantly inhibited, compared to those of control without Cortex mori pretreatment, and 4)the level of cAMP of RPMC was reduced bythe increased concentration of compound 48/80, pretreatment of Cortex mori not only inhibited the compound 48/80-induced reduction of CAMP but also significantly increased the level of cAMP naturally, from the above results, it is suggested that Cortex mori has an some substances with an ability to inhibits the compound 48/80-induced AS,CR, and mast cell activation.

This study is purpose to trace a genealogy of Rainbow stripe in 30 ethnic costumes in East Asia. And with through comparative views between Korean and the other minority that is shown a bilateral relation of rainbow stripe in their costume, we make sure the unique character of rainbow stripe in Korean traditional costume. The stripe in the costumes was generally used on sleeves with 3~6 patches. There were 10 types of methods for making the stripe including sewing. Weaving and sewing with trimming was also frequently used either and the stripe by weaving with multicolored yarns were mostly found in the southern region of china. Black, blue and red were frequently used in the costume as a main color that was contrasted with rainbow stripe and especially, black was mostly used. Korean preferred bright colors as a main color. Contents of the genealogy of the multicolored stripe in ethnic costume in East Asia are followed. The 28 ethnic groups who used the stripe in their dress except Korean, the Mans, Mongo people and Tibetan were located in the southern region of East Asia. And the other ethnic groups distributed in the northwest and northeast region of East Asia. The distribution of the rainbow stripe in the costume could be grouped into two sections: the southern region people and Korean-the Mongol people-the Tus- the Zangs group. And the latter group was shown strong relation with the culture of Korean's rainbow stripe costume. 11 ethnic peoples including Korean, the Vis, the Miaos, the Tus, the Mongol people, the Chaoxians, the Zangs, the Lahus, the Jinuos, the Hanis, the Luobas and the Dulongs, were saliently used the stripe in their costume. The stripe in Japanese costume was judged that was not a kind of the rainbow stripe was shown the other ethnic groups, was a color arrangement by layered dress or geometrical pattern. From above, we could recap a particular characteristic of the rainbow stripe in Korean traditional costume. Many colors were used in the stripe and bodies than the other ethnic people and the color was bright. In many cases, a color of patch at the point of armhole was red and Black color was not used in the stripe. The width of patch was a relatively narrow and regular. It has shown that the rainbow stripe in Korean traditional costume was organized independently.

Recently, the improvement of virtual reality and augmented reality technologies leverages many new technologies like the virtual study room, virtual architecture room. Such virtual worlds require free handed drawing technology such as writing descriptions of formula or drawing blue print of buildings. In nature, lots of view point modifications occur when we walk around inside the virtual world. Especially, we often look some objects from near to far distance in the virtual world. Traditional drawing methods like using fixed size image for drawing unit is not produce acceptable result because they generate blurred and jaggy result as view distance varying. We propose a novel method which robust to the environment that produce lots of magnifications and minimizations like the virtual reality world. We implemented our algorithm both two dimensional and three dimensional devices. Our algorithm does not produce any artifacts, jaggy or blurred result regardless of scaling factor.

The purpose of this study is to offer data that designers can utilize substantially, by developing creative materials in knit fashion through the analysis relevant to expression characteristics on the mixture in high low class culture, which were shown in knit fashion of contemporary women, as one of methods of pursuing a plan for being able to be appeared creative and unique knit wear. As for a method of this research, studied concept and characteristics on the mixture in high low class culture by preceding researches. And women's knit fashion was selected that is seen to be 3~18 gauge among the world's 4 collections from 2000~2008. The analysis was made with the analytical frame in mixture pattern, and the analytical frame in design element, and item. The results are as follows. The mixture of kidult element and high fashion was shown with characteristic of expressing humor and fun with graffiti, expression like character and cartoon, and fairy-tale fantasy through the exaggerated trifling article. The mixture of grungy element and high fashion was shown with the expression characteristic in the mixture of heterogenous pattern, and in tear, slit without the end treatment due to fraying the end strand in the knit fashion with basic stitch, patch work, fringing and tone-down gray, use of khaki and blue color, and match in opposite color. The mixture of underwear and high fashion was shown the expression characteristic with the emphasis on underwear line like volume up, or with the mixture of details such as pants in diverse lengths, mini skirt, underwear lace, and ribbon.

The purpose of this study was to be of use for more successful prediction of possible Prevailing aesthetic characteristics in the future, by reviewing how decadent features have actually been unfolded in fashion and make-up since the end of 20th century, as we are now in the new 21st century. The decadent traits of modern fashion and make-up since the late'90s could be listed as follows : first, the fashion has intentionally been designed to look disgusting, where realistic and imaginary images coexist, by using a half-man, half-machine image or vividly describing detestable animal skin, There have also been disgusting features in the make-up, which are so extremely weird that we can created by adding vinyl or pieces of textiles like Patch of the 17th century. Second, the satanic character of the fashion seems to be meant to keep in harmony with evil image such as Dracula, witch, skeleton or warrior of the evil, in order to charge the unnatural, inhuman and fin-de-siecle Phenomenon and find out what It really means for the inner world of men. And the demonic expressions of the make-up chiefly use white or black color or blue color of low saturation or low lightness, and part of facial features is exaggerated or shortchanged. Third, the decadent characteristics are expressed in the fashion by attaching sensational ornament to the human bode or using sexual exposure. So they give unnatural, unsound and extremely erotic impressions. The decadent features in the make-up are generated by excessively using a gay red color or sensational, exciting colors. Fourth, the exoticism of the fashion is largely affected by China's Chipaoh, Japan's Kimono or primitive motives from Africa, as there are increasing interests in Asia. And that of the make-up leans toward the East, as Kabuki make-up from Japan, Kyongkeuk make-up from China or the primitive features from Africa are employed.

An outbreak of the onion thrips, Thrips tabaci, was observed in welsh onion cultured in greenhouse during winter season (Jan ~ Feb). The thrips was identified using DNA barcode. Weekly occurrence was around 240 ~ 700 adults per trap. Trap color gave significant influence on the capture efficiency with a preference on yellow compared to blue sticky trap. Subsequently, most (> 90%) onions exhibited a damage symptom induced by the thrips. This outbreak was observed only in a specific area but not in nearby greenhouses. This discontinuous occurrence pattern was further investigated by analyzing flight behavior through in- and out- door tests. About 1.5 mm-body length adults could jump up to about 5 cm and fly up to 2 m in altitude, which was the top of the greenhouse. This suggested their migrating potential to nearby (< 2 m) greenhouses. However, few were detected in the neighboring places probably due to physical hindrance with low temperatures between greenhouses. This is reasoned why the onion thrips forms a patch distribution among greenhouses during winter season.

Background: Naringenin (NRG) is a common dietary polyphenolic constituent of fruits. NRG has diverse pharmacological activities, and is used in traditional medicine to treat various diseases including gastrointestinal (GI) disorders. Interstitial cells of Cajal (ICCs) are pacemaker cells of the GI tract. In this study, the authors investigated the effects of NRG on ICCs and on GI motility in vitro and in vivo. Methods: ICCs were dissociated from mouse small intestines by enzymatic digestion. The whole-cell patch clamp configuration was used to record pacemaker potentials in cultured ICC clusters. The effects of NRG on GI motility were investigated by calculating percent intestinal transit rates (ITR) using Evans blue in normal mice. Results: NRG inhibited ICC pacemaker potentials in a dose-dependent manner. In the presence of tetraethylammonium chloride or iberiotoxin, NRG had no effect on pacemaker potentials, but it continued to block pacemaker potentials in the presence of glibenclamide. Preincubation with SQ-22536 had no effect on pacemaker potentials or on their inhibition by NRG. However, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one blocked pacemaker potential inhibition by NRG. In addition, L-NG-nitroarginine methyl ester blocked pacemaker potential inhibition by NRG. Furthermore, NRG significantly suppressed murine ITR enhancement by neostigmine in vivo. Conclusion: This study shows NRG dose-dependently inhibits ICC pacemaker potentials via a cyclic guanosine monophosphate/nitric oxide-dependent pathway and $Ca^{2+}$-activated $K^+$ channels in vitro. In addition, NRG suppressed neostigmine enhancement of ITR in vivo.

This thesis is a study on the kaftan styles iin Asia. The purpose of he study was to examine the origin o the kaftan concentrating on the history and cultural backgrounds of nomads in he Western Central and North Eastern Asia. Secondly for more thorough study and expla-nation on how these kaftans contributed to East-West trade along the silk road. wall paintings and miniature illuminations along Oasis roads persia and Saracen period were compared, Also real kaftans were compared and analyzed the characteristics of Western (Turkey palestine) Central(Kazakistan Uz-bekistan Tadzhistan Qyrgyztan Turkmenistan) and the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the style classifications according to their peculiarities of the various kaftans as well as how kaftan gave important influences on custumes of different religious sects. The kaftan is a long coat-like garment with front openings fastened with long sash having an extra long sleeves which were worn by middle and high class nomadics throughout the West Central and North Eastern Asia This type of kaftans were a basic clothing for nomadics since they were constantly moving fromone to another areas on their horse back riding. They also wore tight trousers with boots. Kaftans seem to be originated from nomads of Steppe around B.C. 800 On B. C 400 west asian areas such as Solokha Kul-oba Kulogan had pictures sculptues on vases showing kaftans of half coat type length with front opening tied with band. Also the materials used were the products of animals such as wool or felt with animal designs showing Scythian nomads. In the North Eastern Asia Hsiung-Nu were active in Kazakha North Altai and Mongol The Clothing and fabrics exfavated near Noin-ula Pazyrik showed many samples of kaftan with trousers with other interment be-longings with a corpse around B.C 300 to A. D 100 when trades along the silk roads were proven by many historians Kaftans excavated in this area wore red front opening silk materials which suggesting settling down of nomads. in he central Asia Dol-gull near Altai mountain area were mainly miners who later had many trades with Persia and Bizantine. After Dol-gull Bezeklik temple Samarkant Kizil cow Budda sculture wall paintings of Astana tomb showed typical kaftan of this re-gion. These were both hip covered length as well as long coat with narrow sleeves. Es-pecially they had different color band fron the main kaftan with grogeously and splendously designed silk. In perusia during A. D 1400 to 1600 minia-ture illumination showed kaftan as a high class symbol more than clothing purpose. They had best quality silk with extra long sleeves draping and had a layers of kaftans one on top of anther as a symbol of wealth These Kaftans with different colors and designs were even more beautiful with their effective combinations and contrast of colors. On the other hand the lower class common people and servants wore simple kaftan with the front part of the kaftan were slipped into the belt in order to be more active and con-venient to work, The real kaftans discovered at Topkapi Saray palace of Turkey from A. D 1300 to 1900 were also compared. These kaftans were very numerous in numbers as well as designs The materials and designs used were also vari-ous such as Chinese to Italian silk. The shaped and pattern itself were not much different from the previous nomad's Kaftans. The Palestian kaftans remained were from the beginning of 19th and 20th century. Since this area is hot and dry desert they used black and navy blue colors mostly in order to exclude the sun lights. The patterns used were similar to Nomads and Bedouin with cross stiches and patch work decorations. In the central Asia they had similar life style and natural environmental cnditions with Turkish tribe which resulted in similar kaftan styles as nomads. Mongols conserved basic patterns of kaftan since Cinggis Khan with deep folding in order to keep warm. At last the kaftans studided in this thesis were classified in to four such as half coat long coat jacket and vest style. A pattern used in the Central Asia were zigzag and ani-mal design whereas in the West Asia were floral plant arabesk and circle pattern. As I discussed previously kaftan styles of nomads in the Asia maintained its basic pat-tern throughout the history except slight changes in color gusset sleeve shapes. These slight changes were made according to the need to adapt the need of environmental natu-ral conditions, The reason for aboriginality of kaftan in Asia was its simplicity and con-venience Most interesting fact is that for all these years Mongols are still wearing kaftan in their life ensuring us that they art the preserves of old kaftan. Since this thesis dealt enormous Asian regions I had a limitation of not being able to cover the Far Esatern asian areas such as Korea China and Japan how these kaftans were influenced in their clothing history as well as Eastern and Western culture. This topic along with the studies on materials and designs of patterns of kaftan will be another research project in the future.
