Dumortiera hirsuta (Sw.) Nees (Dumortieraceae) is a thallose liverwort distributed in tropics and subtropics. It is the only species in family Dumortieraceae, which is the second basal family in order Marchantiales. D. hirsuta is characterized by hairy receptacles and lacking air chamber. The complete chloroplast genome of D. hirsuta was successfully rescued from raw reads generated by HiSeq4000. Its total length is 122,050 bp consisting of four regions: large single copy (LSC) region (81,697 bp), small single copy (SSC) region (20,061 bp), and two inverted repeats (IRs; 10,146 bp per each). It contained 129 genes (84 coding DNA sequence (CDS), eight rRNAs, and 37 tRNAs); 18 genes including four rRNAs, and five tRNAs are duplicated in the IR regions. The overall GC content of D. hirsuta is 28.7%, which is almost same to that of Marchantia paleacea. Phylogenetic tree based on all genes from whole chloroplast genomes will provides phylogenetic position of D. hirstua. This sequence will be an fundamental resources for further researches of order Marchantiales.

Eleocharis R. Br. (Cyperaceae) is characterized by unbranched culms, one terminal spikelet, bisexual flowers, and bristly perianths, occurring mainly in circumboreal marshes and wetlands. There are about 250 species worldwide, and 15 taxa in Korea have been recognized. Chromosomes in Cyperaceae are known to be holocentric, missing constricted centromeres during cell division. For the first time, we report the chromosome counts of Eleocharis from Korean populations of E. attenuata f. laeviseta (Nakai) H. Hara (2n = 20); E. parvula (Roem. & Schult.) Link ex Bluff, Nees & Schauer (2n = 10); E. ussuriensis Zinserl. (2n = 16); and E. valleculosa var. setosa Ohwi (2n = 16). The populations exhibit variations in their chromosome sizes from ca.1.7 ㎛ to ca. 6 ㎛, categorized as gradient and bimodal karyotypes. The karyotypes observed are congruent with previous phylogenetic groups proposed. To clarify the traditional and phylogenetic classification of Korean Eleocharis, further taxonomic and chromosomal investigations with additional taxon sampling efforts are required.

After translating the contents of "Treatise on Bundon Disease in Chapter 8 of the Essence of the Synopsis of the Golden Chamber" and it was compared with the contents of "The Lecture of Synopsis of Prescriptions of the Golden Chamber" and speculated to review the characteristics of the comments of Ui(尤怡) and the following conclusions were made. As the causes of bundon(奔豚) disease, which means gas rushing like a running piggy from the lower abdomen to the throat, they could be categorized into the cases belongs to miscellaneous diseases (雜病) and into the cases of suffering from cold diseases(傷寒). If it was diagnosed as miscellaneous disease, terror and fear(驚恐) could be regarded as its cause and if it was diagnosed as cold disease, insufficiency of heart Gi(心氣) due to the excessive sweating and the invasion of exterior coldness could be regarded as its cause. As the pathogenesis of this disease, the pathogenic factors of liver and kidney could be found. Since the liver and Soyang meridian(少陽經) are subjected to the exterior and interior relation in case of the pathogenic factor of liver, alternate attacks of chills and fever(寒熱往來) could be characteristic for the disease. If this disease was caused by the pathogenic factor of kidney, there are two cases. One is the palpitation under the umbilicus(欲作奔豚: 臍下動悸) developed by the lack of heart Gi(心氣) and the other is gas rushing like a running piggy from the lower abdomen to the throat which could be developed by the exterior cold disease which invade into the interior and reach into the kidney when the heart Gi(心氣) was insufficient. In its treatment, bundon disease caused by the pathogenic factor of liver could be treated with Bundontang(奔豚湯), and the understanding of Ui(尤怡) on Pinellia ternata Breitenbach(半夏) having the effect of perspiration in the prescription is quite unique concept. In case of bundon disease caused by the pathogenic factor of kidney, treatment is focused to treat exterior coldness by applying moxibustion(灸) and Gyejigagyetang(桂技加桂湯), and in case of the palpitation under the umbilicus(欲作奔豚: 臍下動悸), its pathogenic factor of kidney is controlled with Cinnamomum louerii Nees(桂技), Polia cocos Walf and the spleen Gi(脾氣) is cared by using Glycyrrhiza uralensis Fischer et. De Candolle(甘草) and Zizyphus jujuba Mill(大棗). Especially, Ui(尤怡) emphasized Cinnamomum louerii Nees(桂技) as the medication to treat the pathogenic factor of kidney.

This study determined the effects of addition of medicinal herb extracts (Zanthoxylum piperitum extract(TZ), Acanthopanax sessiliflorus(TA), Panax ginseng(TP), Cinnamomum lureitri Nees(TC), Angelica gigantis radix(TAG) and Crataegii fructus extract (TCF) to teriyaki sauce with regard to taste and health benefit. After adding the medicinal herb extracts to teriyaki sauce, moisture content was found to be inversely proportional to the viscosity. The sauce with Panax ginseng extract(TP) had lowest sweetness, but highest salinity. The results showed that the sauce with Korean herb extracts had lower salinity content. In terms of colour value, the sauce with Crataegii fructus extract(TCF) had much higher lightness, redness, and yellowness than sauce prepared with other herb extracts. It had the strongest acidic taste and lowest pH. Sensory evaluation test revealed that the sauce with Anthoxylum piperitum extract(TZ) was the most preferred sauce among all the sauces tested. The degree of brown color of teriyaki sauces was correlated positively with taste preference(r=.570, p<0.01) and overall preference(r=.505, p<0.01).

This study attempted to examine the differences between male and female juveniles from the perspective of the parentification and to discover if the differences in the effects of shame and guilt proneness on the parentification of juveniles according to gender were observed under the control of negative family environment variables. With this purpose in mind, the researcher measured negative family environments, and the shame proneness, guilt proneness, and parentification of 225 male and 243 female students in middle schools in Seoul. The results indicate that there were differences in the levels of parentification according to gender male juveniles showed higher levels of parentification than female juveniles. In addition, after negative family environment variables were under control, both shame proneness and guilt proneness effected the parentification. Furthermore, while the effects were different according to gender, guilt proneness had a significant effect on parentification for males and shame proneness had a significant effect on the parentification for females. In conclusion, it was suggested that female's parentification as effected by shame proneness nees to be be noted although male juveniles showed higher levels of the parentification.

Numerous devices exist for reducing or eliminating seismic damage to structures. These include passive dampers, semi-active dampers, and active control devices. The performance of structural systems with these devices has often been evaluated using numerical simulations. Experiments on structural systems with these devices, particularly at large-scale, are lacking. This paper describes a real-time hybrid testing facility that has been developed at the Lehigh University NEES Equipment Site. The facility enables real-time large-scale experiments to be performed on structural systems with rate-dependent devices, thereby permitting a more complete evaluation of the seismic performance of the devices and their effectiveness in seismic hazard reduction. The hardware and integrated control architecture for hybrid testing developed at the facility are presented. An application involving the use of passive elastomeric dampers in a three story moment resisting frame subjected to earthquake ground motions is presented. The experiment focused on a test structure consisting of the damper and diagonal bracing, which was coupled to a nonlinear analytical model of the remaining part of the structure (i.e., the moment resisting frame). A tracking indictor is used to track the actuator ability to achieve the command displacement during a test, enabling the quality of the test results to be assessed. An extension of the testbed to the real-time hybrid testing of smart structures with semi-active dampers is described.

Accurate actuator tracking plays an important role in real-time hybrid simulation (RTHS) to ensure accurate and reliable experimental results. Frequency-domain evaluation index (FEI) interprets actuator tracking into amplitude and phase errors thus providing a promising tool for quantitative assessment of real-time hybrid simulation results. Previous applications of FEI successfully evaluated actuator tracking over the entire duration of the tests. In this study, FEI with moving window technique is explored to provide post-experiment localized actuator tracking assessment. Both moving window with and without overlap are investigated through computational simulations. The challenge is discussed for Fourier Transform to satisfy both time domain and frequency resolution for selected length of moving window. The required data window length for accuracy is shown to depend on the natural frequency and structural nonlinearity as well as the ground motion input for both moving windows with and without overlap. Moving window without overlap shows better computational efficiency and has potential for future online evaluation. Moving window with overlap however requires much more computational efforts and is more suitable for post-experiment evaluation. Existing RTHS data from Network Earthquake Engineering Simulation (NEES) is utilized to further demonstrate the effectiveness of the proposed approaches. It is demonstrated that with proper window size, FEI with moving window techniques enable accurate localized evaluation of actuator tracking for real-time hybrid simulation.

Andrographis paniculata (Burm. F.) Wall. Ex Nees (Family: Anthaceae) is a traditionally known Ayurvedic medicinal plant. Several well-controlled clinical trials conducted during recent years have consistently reconfirmed that Andrographis paniculata extracts are effective in suppressing cardinal symptoms of diverse inflammatory and infectious diseases. Despite extensive efforts though, many questions concerning bioactive constituents of such extracts and their modes of actions still remain unanswered. Amongst diverse diterpene lactones isolated to date from such extracts, andrographolide is often considered to be the major, representative, or bioactive secondary metabolite of the plant. Therefore, it has attracted considerable attention of several drug discovery laboratories as a lead molecule potentially useful for identifying structurally and functionally novel drug. Critical analysis of available preclinical and clinical information on Andrographis paniculata extracts and pure andrographolide strongly suggest that they are pharmacologically polyvalent and that they possess adaptogenic properties. Aim of this communication is to summarize and critically analyze such data, and to point out some possibilities for more rationally exploiting their adaptogenic properties for discovering novel therapeutic leads, or for obtaining pharmacologically better standardized phyto-pharmaceuticals.

An investigation was carried out to know the host range of the rice stripe virus as a basis of the disease control. 1. In order to investigate the host range of the rice stripe virus 30 species including gramineaceae and forage crop and weeds were inoculated with viruliferous Laodelphax sriatellus Fallen. As a result, 21 out of 30 species showed typical symptoms. 2. Cyperus amuricus Maximowicz var. laxus., Pycreus sanguinolentus Nees. and Eriocaulon robustius Makino, not belonging to gramineaceae were known to be new host plants of rice stripe virus. The highest infection occurred on Pycreus sanguinolentus grown widly in the wet paddy fold. 3. The number of vectors inoculated on the plants was decreased after 48 hours than that of 24 hours.
