"Bonchogyeongjipju(本草經集注)" is a pharmacological classic published in the Southern and Northern Dynasties(南北朝時代, 420-589 A.D.) in China by Dohonggyeong(陶弘景, 456-536 A.D.). In "Bonchogyeongjipju(本草經集注)", Dohonggyeong(陶弘景) edited "Sinnongbonchogyeong(神農本草經)", the earliest classical text about material medica containing notes for 365 drugs, by adding another 365 drugs and further information from "Myeong-uibyeollok(名醫別錄)" and writing extended commentaries on them. His commentaries include changes in the geographical distribution, identification of varieties and other various special characteristics. The original text had gradually disappeared after other pharmacological classics were published such as "Sinsuboncho(新修本草)", in Dang Dynasty(唐代), "Gyeongsajeungryubigeupboncho(經史證類備急本草)" in Song Dynasty(宋代). All of these books were based on "Bonchogyeongjipju(本草經集注)", so the original text can be seen indirectly through these later sources. In the early 1900's, a transcribed manuscript of the preface "Bonchogyeongjipju(本草經集注)" was found almost wholly preserved except the first three lines, in the Makgo(莫高) cave of Donhwang(敦煌). Broken strips of transcribed "Bonchogyeongjipju(本草經集注)" have also been excavated in Turfan[吐魯番], which shows its original form written in red and black ink. Mayanagi Makoto[眞柳誠] researched on Donhwang(敦煌) and Turfan[吐魯番] editions, ascertained their existence and explained their bibliographical and historical facts. Sangjigyun(尙志鈞) restored "Bonchogyeongjipju(本草經集注)" based on other related sources such as Donhwang(敦煌) and Turfan[吐魯番] editions. " Bonchogyeongjipju(本草經集注)" can be said as the locus classicus(典範) of herbal medicine, that is most of the following materia medica was based on it. It makes it possible to pass down "Sinnongbonchogyeong(神農本草經)" to posterity and provide a foundation for herbal medical development.

Purpose : To address the ability of Dohaekseungkitang (DST: a commonly used herb formulation in Korea, Japan and China to have anti-cancer effect on cervical carcinoma), we investigated the effects of DST on programmed cell death (apoptosis) in HeLa human cervical carcinoma cells. Methods : We cultured HeLa cell which is human metrocarcinoma cell in D-MEM included 10% fetal bovine serum(Hyclone Laboratories) below $37^{\circ}C$, 5% CO2. Then we observed apoptosis of log phage cell which is changed cultivation liquid 24 Hours periodically. Results : After the treatment of DST for 48 hours, apoptosis occurred in a dose-dependent manner. In this study, we have shown that DST induces calpain and the associated caspase-8 and -9 activations. Apoptosis was prevented by pre-incubation of the cells with the calcium cHeLator-BAPTA-AM, calcium channel blocker-Nif edipine or Ryonidine agonist-Ryonidine peptide, implicating calcium in the apoptotic process. Ubiquitous calpains (mu- and m-calpain) have been repeatedly implicated in apoptosis, especially in calcium-related apoptosis. However this study showed 1hat either calpain inhibitor-calpastin or caspase-3 inhibitor-DEVD- did not blocked the herb formulation-induced apoptosis in HeLa human cervical carcinoma cells. D ST initiates a cell death pathway that is partially dependent of caspases. DST-induced apoptosis requires caspase-independent mechanism. Conclusion : We conclude that DST-induced calpain activation triggers the intrinsic apoptotic pathway in which caspase-independent mechanism is also involved.

Background : As the characterization of medicinal plants is an important aspect of traditional Asian herbal medicine, this study examines the morphological and anatomical characteristics in four fructus form medicinally important plants belonging to the family Apiaceae. Methods and Results : Fruit morphology of four genera was examined using microtome sections and light microscopy. The Anethi Fructus, Anethum graveolens (Siraja) has unique wing-like and membranous lateral ribs that are, approximately $500{\mu}m$ wide. The Coriandri Fructus, Coriandrum sativum (Hoyuja) does not have oil ducts at the dorsal region of the mericarp and differs in the development of the dorsal ribs. The ribs appear upon drying and therefore, consist of primary and secondary ribs. The Foeniculi Fructus, Foeniculum vulgare (Hoehyang) characteristically develops three dominant dorsal ribs and has a strong aromatic fragrance. Finally, the Cnidii Fructus, Torilis japonica (Sasangja) has many oil ducts at the dorsal and carpophores regions and develops many hooked trichomes one the fructus surface. Conclusions : We conclude from this study that each plant has several prominent and distinguishing morphological and anatomical characteristics. Therefore, fruit morphology is very useful for identifying these medicinal plants. In addition, the correct use and herbal name need to be standardized for plants used traditionally in Asian medicine within Korea, China, and Japan.

Background: The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. Methods: Male Sprague-Dawley rats were implanted with an intrathecal catheter. Rats were randomly treated with a vehicle and SOG ($10{\mu}g$, $30{\mu}g$, $60{\mu}g$, and $100{\mu}g$) before formalin injection. Five percent formalin was injected into the hind-paw, and a biphasic reaction followed, consisting of flinching and licking behaviors (phase 1, 0-10 min; phase 2, 10-60 min). Naloxone was injected 10 min before administration of SOG $100{\mu}g$ to evaluate the involvement of SOG with an opioid receptor. Dose-responsiveness and ED50 values were calculated. Results: Intrathecal SOG showed a significant reduction of the flinching responses at both phases in a dose-dependent manner. Significant effects were showed from the dose of $30{\mu}g$ and maximum effects were achieved at a dose of $100{\mu}g$ in both phases. The ED50 value (95% confidence intervals) of intrathecal SOG was 30.3 $(25.8-35.5){\mu}g$ during phase 1, and 48.0 (41.4-55.7) during phase 2. The antinociceptive effects of SOG ($100{\mu}g$) were significantly reverted at both phases of the formalin test by naloxone. Conclusions: These results demonstrate that intrathecal SOG has a very strong antinociceptive effect in the formalin test and it seems the effect is related to an opioid receptor.

A novel ${\beta}$-proteobacterium, designated BXN5-$27^T$, was isolated from soil of a ginseng field of Baekdu Mountain in China, and was characterized using a polyphasic approach. The strain was Gram-staining-negative, aerobic, motile, non-spore-forming, and rod shaped. Strain BXN5-$27^T$ exhibited ${\beta}$-glucosidase activity that was responsible for its ability to transform ginsenoside $Rb_1$ (one of the dominant active components of ginseng) to compound Rd. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belonged to the family Comamonadaceae; it was most closely related to Ramlibacter henchirensis $TMB834^T$ and Ramlibacter tataouinensis$TTB310^T$ (96.4% and 96.3% similarity, respectively). The G+C content of the genomic DNA was 68.1%. The major menaquinone was Q-8. The major fatty acids were $C_{16:0}$, summed feature 4 (comprising $C_{16:1}$ ${\omega}7c$ and/or iso-$C_{15:0}$ 2OH), and $C_{17:0}$ cyclo. Genomic and chemotaxonomic data supported the affiliation of strain BXN5-$27^T$ to the genus Ramlibacter. However, physiological and biochemical tests differentiated it phenotypically from the other established species of Ramlibacter. Therefore, the isolate represents a novel species, for which the name Ramlibacter ginsenosidimutans sp. nov. is proposed, with the type strain being BXN5-$27^T$ (=DSM $23480^T$ = LMG $24525^T$ = KCTC $22276^T$).

A new simple 3-node triangular flat-shell element with standard nodal DOF (6 DOF per node) is proposed for the linear and geometrically nonlinear analysis of very thin to thick plate and shell structures. The formulation of element GT9 (Long and Xu 1994), a generalized conforming membrane element with rigid rotational freedoms, is employed as the membrane component of the new shell element. Both one-point reduced integration scheme and a corresponding stabilization matrix are adopted for avoiding membrane locking and hourglass phenomenon. The bending component of the new element comes from a new generalized conforming Kirchhoff-Mindlin plate element TSL-T9, which is derived in this paper based on semiLoof constrains and rational shear interpolation. Thus the convergence can be guaranteed and no shear locking will happen. Furthermore, a simple hybrid procedure is suggested to improve the stress solutions, and the Updated Lagrangian formulae are also established for the geometrically nonlinear problems. Numerical results with solutions, which are solved by some other recent element models and the models in the commercial finite element software ABAQUS, are presented. They show that the proposed element, denoted as GMST18, exhibits excellent and better performance for the analysis of thin-think plates and shells in both linear and geometrically nonlinear problems.

In this paper, we propose a new real-time ground motion monitoring system using MMA data which can be gathered more earlier than generic seismic data transmission method. Proposed system receives maximum, minimum and average data based on 20sps which is sent from station on every second continuously. And it calculates a PGA as a quantity of ground motion then visualizes that data to monitor the ground motion around whole country. To verify PGA data from MMA data, we checked Mu-dan-jang earthquake data of China on 2002/6/29. The proposed system was inspected by using log file of Oh-dae-san earthquake data on 2007/1/20. As results of experiment, the proposed system is proven to detect the event(earthquake) faster then existing method and to produce a useful quantitative information.

For several decades, Asian nations such as Korea, Japan and China have been leading the shipbuilding industry since the decline in Europe and America. However, several developing countries such as India, Brazil, etc. are going to make an entrance into the shipbuilding industry. These developing countries are finding technical partners or information providers because they are in situation of little experiences and technologies. Now, the shipbuilding engineering companies of shipbuilding advanced countries are getting a chance of engineering business against those developing countries. The starting point of this business model is green field project for the construction of new shipyard. This business model is started with a design of the shipyard layout. For the conducting of the shipyard layout design, four kinds of engineering parts are required. Those are civil engineering, building engineering, utility engineering and production layout engineering. Among these parts, production layout engineering is most important because its result is the foundation of the other engineering parts and it determines the shipyard capacity during the shipyard operation lifecycle. Previous researches about the shipyard layout design are out of the range from the business requirements because most research cases are in the tower of ivory, which means that there are little consideration of real ship and shipbuilding operation. In this paper, a shipyard layout design for preliminary phase is conducted for the target of newly planned shipyard at Venezuela of South America with an integrated method that is capable of dealing with actual master data from the shipyard. The layout design method of this paper is differentiated from the previous researches in that the actual product data from the target ship and the actual shipbuilding operation data are used for the required area estimation.
