  • The mosquito, Aedes albopictus is important vector of humen phatogen such as dengue fever. And Aedes albopictus has widly distribution in oriental regions. This study was conducted to investigate the biological effects of cooper on the development of the Asian tiger mosquitoes, Aedes albopictus (Skuse). Aedes albopictus was affected with pupation ratios, mortalities, and wing lengths of the 3th and 4th instars by exposure to different concentration $CuCl_2$ (0.0, 2.5, 25.0 and 50.0 ppm) for 24 h and 48 h depending on dose and exposure period. The lowest $LC_{50}$ (median lethal concentration) value of $CuCl_2$ was 18.1 ppm at the 3rd instars for 48 h exposure. The pupation ratio of the larvae exposed at 50.0 ppm for 48 h was 14% which was much lower than those exposed to other treatment groups Changes of adult wing length showed significant decreased by Cu treatment. In conclusion, the most prominent effects of high concentration and longer exposure period were to reduce in the survival and pupation rates of larvae and wing length of Ae. albopictus.

  • This study is consider·ed about the relation or costume among Parhae, ancient Japan and Tang and the culture of this time commonly was influenced by Tang;s culture. The recorded items, which were exchanged from Parhae to Tang and ancient Japan, are the pelt of marten, seal, bear and tiger skin or Ammowhaha(암모화) Gu(구) and so on. Other items from Tang and ancient Japan to Parhae are various clothes and material like silk and so on. This Parhae's clothes made with leather obtained through hunting were the main product of Parhae and had been greatly famous in Tang and ancient Japan. At that time, Tang and ancient Japan had been only dependent on the agricultural life but had not been accustomed to the hunting life, and thereupon, the people in Tang and Nara Era had difficulties to get leather clothes. Accordingly, the leather products stood for the rich, and the people who purchased the leather products from Parhae were recognized as the rich. On the other hand, The prince and the royal family in Parhae were dispatched to Tang as Sooktwui(숙위). They paid a tribute to Tang and In return for it, Tang gave to Sookwui as well as to Parhae's envoys various items and clothes such as Po(포), belt(대), gold and silver Eodae(어대) and textile like a type of silk. These clothes were considered as the formal uniform like Kwanbok(관복) of Parhae. Specially, the time when Sookwui was sent to Tang rot-responded with the time when Tang gave formal uniform to Parhae's envoys. Therefore, we can confirm that the sending of Sookwui influenced to form uniform system of Parhae. In this exchange relation, there were several duplicated items showed, for example Po(포)-belt(대), Eui set(의일습), Eoeui(어의), Jobok(조복), Go(고). These items in Parhae were appeared in process of exchanging from Tang to Japan and from Tang to Parhae. At that time, the exchanges between Tang and Parhae were frequently active much more than those between Tang and Japan, and the acceptance of the culture from Tang was easier in Parhae than Japan in consideration of the geographical location. Therefore, those clothes could be understood as the items already used in Parhae and affected from Tang. These items in Parhae were appeared in process of exchanging from Tang to Japan and from Japan to Parhae. As a result, it is expected that the costumes, which Parhae took from Japan, are the same as those of Tang.

  • The purpose of this study was to control root-knot nematode, Meloidogyne incognita on pumpkin seedling with 10%, 20% coffee ground compost and 1% plant velvet bean powder (plain skin bean, leopard skin bean, hole plant, bean pod). Among the root-knot nematode insecticide treatments, the velvet bean plant powder was the highest mortality rate with 83.2% in greenhouse condition. In addition, the root-knot nematode second juvenile mortality significantly increased with the lapse of processing time for each concentration of leopard skin velvet bean extract in vivo. After 24 hours, the mortality rate of root-knot nematode showed the highest at 1.2% and 2.4% of leopard skin velvet bean extract. The growth promoting effect of seedlings pumpkin, 20% of coffee ground compost treatments inhibited the growth of pumpkin seedlings and 1% the tiger pattern velvet beans powder was the most to promote the growth of pumpkin seedlings. However, the results indicated that the organic materials of velvet beans and coffee ground compost are expected to be able to effectively control the root-knot nematode and further studies will be needed for the concentration and application methods.

  • The purpose of this study is to figure out how stage costume of Peking Opera communicates what the character wants to inform to spectator. The stage costume means the clothing, shoes, headdress, accessory that the cast is worn for communicating personality of character. Stage costume not only reveals the character of new spirit who the director and the work is like to create, but also makes the style of play harmonizing with the atmosphere of the work. So, the stage costume in the play is a sort of symbol system that forms the depth of play. The stage costume of Peking Opera was formed on the basis of the Chinese traditional stage costume in the Qing period, however the style of stage costume was beautified the costume of Ming period and here contained the factors of successive costumes. But the stage costume of Peking Opera don't have the same rank system with real history costume and don't have demarcation according to period and history. Only it is that transformed and created the real history costume with Chinese fine view and made how they wear Chinese fine view and made how they wear the costume according to position, age, personality of character in the play. In the stage costume of Peking Opera, the color is cultural language that director can communicate to spectators and can inform spectator of sex, age, personality, position of the character. The color of the stage costume of Peking Opera reflects the principles of Yin and Yang and the five elements of the Chinese cosmogony. The pattern of decoration also makes the personality and characteristic of the character. The dragon pattern symbols the authority and majesty, so only the character of high position can use it. The pattern of tiger and leopard symbols bravery, so the military officer can use it. Civil officer decorates with the pattern of Japanese apricot, orchid, chrysanthmum, bamboo that symbols integrity and honor. The stage costume of Peking Opera communicates the identity of character with the special form of costume. Kanjien is a costume of the young priestess, Houyi is the Sunwukong'costume. Chayi is a costume of boatman. Lingzi, Sweixiu, Kaoqi is the props for the foramtive effect of stage costume, also they play an important part in expressing the emotion situation. In the result of study, we could know that the form, color, pattern of the stage costume and props of Peking Opera play important parts in communicating informations that let spectator can understand the play. So, the stage costume of Peking Opera is an‘picturizing costume’that the form, color, pattern of the stage costume is a sort of symbol system. It makes spectator feels actually the viewing Peking Opera.

  • Complete larval development Orithyia sinica (Linnaeus) is composed of three zoeal ins-tars and megalopa. Survival of instals was higher in $20^{\circ}C$ than in ambient temperature. Intermolt period generally increased with the increase of number of instals, but a notable decrease was observed from Crab-5 to prepuerty molt instals(Crab-7). Zoeas and me-galopa reared at higher temperature regime were samller than those reared at lower temperature. No temperature effect was shown in the size of crab instals. Growth factors fluctuate with the increase of number of instals, but there was an overall trend of net decrease. Growth factor was $35.65\~41.4\%$ for zoeal instals, and they were $18.00\~30.91\%$ for crab instals.

  • The costumes on a royal ceremony and the changes thereafter during the Korea Empire(1897-1910) have been elucidated through the review on the paintings on Queen Myong-Hun's 70th birthday celebration and the prospectus of the ceremony. Queen Myong-Hyn wore ceremonial gown in deep blue with 51 embroidered phoenix on it. The deep blue color the royal color in the Korea Empire replaced former red color. Go-jong wore violet crown and ceremonial suit in gold color. Twenty one kinds of court dance were offered during the celebration ceremony. Costumes therein appear to have an order according to the role ofdancers. most female dancers(in 17 performances not else-where specified) wore a rather common cos-tume-flower cap outer silk garent in green hand veils in 5 colors silk skirt in red) embroidered silk belt in red and shoes in green. In Sun-you-ak two female lead dancers were red hat decorated with tiger whisker deep blue outer garment wide red belt silk boots in black bow and arrows on back and a sword and a whip in hands. In Choonaang-jon a fe-male solo dancer wore a silk outer garment in yellow silk skirt in red green lorum embroidered silk belt in red wrist band of gold embroidered red silk and 5 color hand veils. In Yon-wha-dae two young girl dancers wore lotus-form crown green outer garment wide pants in red silk red silk skirt red silk belt hand veils in jade color and silk shoes in deep red. In Moo-go 4 female dancers each wore long waist coat in blue red white and warm light green in addition to the above-mentioned common costume. In Gumkee-moo 4 female dancers wore hatlike wool helmet outer garment with narrow sleeve long silk waist coat in blue combat belt in deep blue silk and dance swords in both hands. In Youk-wha-dae 6 female dancers each wore a long waist cost in red deep blue violet pale pink green and jade color. Green color of outer garment in the above-mentioned common costume of female dancers appears intersting. Although the color was shown as yellow in the screen paintings actually it was green as evidenced by the prospectus of the celeebration ceremony.

  • Purpose : The purpose of the study was to examine if a respiratory muscle strengthening training in patients with stroke can improve their pulmonary function. Methods : Volunteers were included for the study if a patient diagnosed stroke more than 6 months and had 24 points or higher in MMSE-K scores. Twenty-eight subjects participated in this study and were randomly divided into two groups; a breathing exercise group(n=14) and a control group(n=14). The intervention for all subjects was conducted for 20minutes, three times a week for 4 weeks. Subjects for the breathing exercise group had the respiratory muscle strengthening training using spiro-tigers, where-as subjects in the control group got their usual treatment ie a postural training. The six-minute walking test(6MWT) and the pulmonary function tests(FVC, $FEV_1$, $FEV_1$/FVC, VC, Vt, IRV and ERV) were employed to assess treatment effects at baseline and after their intervention. Results : Twenty-four subjects finished their 4-week treatment programs. The general characteristics between groups were found to be similar (p>0.05). The pulmonary function between groups were also observed no difference across groups at the baseline measurement (p>0.05). In the post treatment group comparison, subjects in the breathing exercise group showed an increase in lung function with VC ($2.73{\pm}0.80{\ell}$) and Vt ($0.87{\pm}0.38{\ell}$) than those in the control group ($1.91{\pm}0.80{\ell}$ and $0.48{\pm}0.22{\ell}$ respectively) (p<0.05). However, there was no difference found in 6MWT, FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV across groups (p>0.05). Conclusion : A significant increase in VC and Vt was found in subjects with stroke, who had four-week training on respiratory muscle strengthening. However, respiratory muscle strengthening showed no effect on walking speed and FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV in patients with stroke.

  • Centella asiatica (CA) has been widely used as herbal plants. It is a valuable resources. The aim of the present study was to evaluate physiological activities of solvent extracts from CA cultivated in Chungju, Korea (Good tiger care). After preparing water (cold-water, CA-WE; hot-water, CA-HWE) and EtOH extracts (50% EtOH, CA-50E; 70% EtOH, CA-70E), their total polyphenol, flavonoid, and triterpenoid contents, and anti-oxidant activities, and anti-inflammatory activities were examined and compared. CA-70E showed the most potent anti-oxidant activity based on ABTS radical scavenging activity and reducing ability assays, while CA-50E and CA-70E showed the highest DPPH radical scavenging activity. Among major triterpenoid glycosides present in CA, madecassoside and asiaticoside contents were found to be the highest in CA-70E, and madecassic acid and asiatic acid were the highest in CA-50E. In LPS-stimulated RAW 264.7 cells, CA-70E showed the highest TNF-α inhibitory activity, although CA-50E and CA-70E similarly inhibited nitric oxide production. Ethanol extracts significantly inhibited IL-6 and IL-8 production more than water extracts using TNF-α/IFN-γ-stimulated HaCaT cells, indicating its better inhibitory against skin inflammation. Therefore, Chungju-CA EtOH extract, especially 70% EtOH extract, has high physiologically active ingredients and potent anti-oxidant and anti-inflammatory activities, suggesting its industrial application as a functional material.

  • This study investigated species identification and labeling compliance of 48 shrimp products sold in the Korean online markets. Species identification was conducted using the standard DNA barcoding method, using the cytochrome c oxidase subunit I gene. The obtained sequences were compared with those deposited in the NCBI GenBank and BOLD Systems databases. Additionally, phylogenetic analysis was performed to further verify the identified shrimp species. Consequently, 16 shrimp species were identified, including Penaeus vannamei, Pandalus borealis, Palaemon gravieri, Leptochela gracilis, Penaeus monodon, Pleoticus muelleri, Metapenaeopsis dalei, Euphausia pacifica, Lebbeus groenlandicus, Trachypenaeus curvirostris, Argis lar, Metanephrops thomsoni, Metapenaeopsis barbata, Alpheus japonicus, Penaeus chinensis, and Mierspenaeopsis hardwickii. The most prevalent species was Penaeus vannamei, found in 45.8% of the analyzed products. A significant mislabeling rate of 72.9% was found; however, upon excluding generic names such as shrimp, the mislabeling rate reduced to 10.4%. The mislabeling rate was higher in highly-processed products (89.3%) compared with that in minimally-processed products (50%). No correlation was found between the country of origin and mislabeling rate. The results of this study provide crucial data for future monitoring of shrimp products and improving the labeling of shrimp species in Korea.

Investigation of the location of Jagiso eunchon in Goheung-hyeon and review the characteristics of Undae-ri kiln (고흥현 자기소(磁器所) 은촌(犾村)의 위치 탐색과 운대리 가마터 성격 검토)

  • As described above, the location of Jagiso eunchon in Goheung-hyeon and the nature of Undae-ri kiln site were examined. Goheung-hyeon's administrative agency was moved to Joyang-hyeon, which is now Joseong-myeon, Boseong-gun in 1395. Therefore, Goheung-hyeon Jagiso Eunchon in Sejongsillok Jiriji corresponding to 1424~1432 should be found in the west of Joseong-myeon, Boseong, where the administrative agency was moved in 1395. Among the four boundaries of Goheung-hyeon recorded in the 『Sejongsillok』 Jiriji, it is recorded as 2-ri by the sea in the south and 8-ri by Nakan in the east. If the current Goheung-hyeon is Goheung-hyeon's administrative agency in the Sejongsillok Jiriji Records Compilation Period, it cannot be the boundary the south and east mentioned above. This is because it cannot be 2-ri from the current Goheung-eup to the sea in the south, and Nakan is close to the north, not the east, as recorded. However, it has already been suggested that Joyanghyeonseong(朝陽縣城), located in Gonae Village, Ucheon-ri, Josung-myeon, Boseonggun is an Goheunghyeon's administrative agency. And if the four-way boundary of Goheung-hyeon was converted into the current distance unit based on this place(Joyanghyeonseong, 朝陽縣城), an approximate result could be obtained even if it did not exactly match. Therefore, it is highly likely that Goheung-hyeon's administrative agency, which was moved to Joyang-hyeon, Boseong in 1395, is Gonae Village, Ucheon-ri, JoSeong-myeon, Boseong. Jagiso eunchon(犾村) in Goheung-hyeon can be interpreted as a "dog-shouting village." It is thought to be a meaning structure of "animal + sound". A place name thought to have the same structure was identified in Jeongheung-ri, west of Ucheon-ri, Joseongmyeon, Boseong. It is the name of a village called Hoeum-dong(虎吟洞), and it is interpreted as the sound of a tiger or the bark of a tiger, which is the same as the meaning structure of Eunchon. However, there is Gaesan Village in the south of Hoeum-dong, and a Buncheong ware kiln site was identified around it. At this kiln site, a fragment of carved Buncheong ware engraved with the character "Eon", which corresponds to the right stroke of the character "Seom (贍)" in the name "Naeseom (內贍)" was identified. A small amount of Buncheong ware and Joseon celadon pieces were also identified. It can be seen that the Buncheong ware paid to the government was made by checking the Buncheong ware with the government name engraved on it. On the west side of Joyanghyeonseong Fortress in Ucheon-ri, joseong-myeon, Boseong, which was the administrative agency of Goheung-hyeon and the area around the Gaesan Buncheong ware kiln site in Jeongheung-ri, where the Buncheong ware paid to the government was, is thought to be Jagiso Eunchon, Goheung-hyeon. Jagiso and Dogiso are located in the four directions based on the administrative agency. Naturally, the location of Jagiso and Dogiso is also determined on where the administrative agency of Hyeon is. Since the Goheung-hyeon's administrative agency in the early Joseon Dynasty was moved to Ucheon-ri, joseong-myeon, Boseong-myeon, it is necessary to naturally find Jagiso and Dogiso in Boseong. In addition, regarding the nature of the kiln site in Undae-ri, the aspects of the excavated relics were considered. As a result, it is believed that the Undae-ri kiln site functioned as a jagiso in Heungyang-hyeon from February 1441 to the 1470s. If so, the "Ye" Buncheong ware, which was collected around Undae-ri kiln No. 7, could be naturally understood.
