The objective of the present study is to investigate parents' satisfaction with taekwondo halls with regard facilities, size, safety, cleanliness, the disposition of the coach (director), management and educational aspects, aiming at increasing the membership of taekwondo halls, improving the health of members, and ultimately developing taekwondo as a sound living sport contributing to education, cultivation of good personality and the improvement of school records. This study selected 8 taekwondo halls under the supervision of Gyeongsangbuk-do Taekwondo Association and run by graduates of Yongin University, all of which were in Pohang, Gyeongsangbuk-do, and sampled parents of higher grade (4^(th), 5^(th), 6^(th) year) elementary school students who were attending the taekwondo hall. The present researcher prepared the tool used in this study by modifying questionnaires used in previous researches, Evaluation of Taekwondo Halls in Seoul pun, Sang-hwa, 1998) and Comparative Analysis of the Image of Middle School Teachers Expected in Korea and Japan (Lee, Mu-sun, 1994), Current State of Educational Environment and Its Improvement &m, Ok-ju, 1997). The questionnaire consists of a total of 35 questions, 5 about background variables, 5 above size and facilities, 5 about safety and cleanliness, 10 about the disposition and specialty of the coach (director), and 15 about satisfaction with management and educational aspects. The present study was carried out for about 3 months from November 2002 to January 2003. The number of questionnaires recovered from the 8 halls was 424. Excluding insincere replies, 283 of them were used in data analysis, for which SPSS WIN 10.0 was used. Frequency analysis was performed for all items, cross analysis was for each question according to the background variables of parents' satisfaction with the educational environment of taekwondo halls, and chi-square test was for testing the significance among groups. The significance level for the analysis was 5%. From the research methods and processes presented above, this study drew the following conclusions. 1) Parents' satisfaction with size and facilities With regard to parents satisfaction with the size and facilities of taekwondo halls by the gender of trainees, 7.7% of the parents replied Not Satisfied , 42.7% Moderately Satisfied , and 51.4% Satisfied , so as a whole, parents were satisfied with the size of taekwondo halls. Parents' satisfaction with the floor condition of taekwondo halls by gender, age, academic qualification and the length of training was 32.9% as a whole, so it was urgently required to improve the facilities of taekwondo halls. 2) Parents' satisfaction with safety and cleanliness With regard to parents' satisfaction with the safety and the cleanliness of taekwondo halls by parents' age, 6.8% of parents replied Not Satisfied , 45.4% Moderately Satisfied , and 47.1% Satisfied , so as a whole, parents were satisfied with the safety and the cleanliness of taekwondo halls. Parents' satisfaction with the safety of hall bus operation by gender, age, academic qualification, and the length of training was 64.5% as a whole, so they were relatively satisfied with the safety of hall bus operation. However, with regard to parents' satisfaction with fire prevention facilities by gender, age, academic qualification, and the length of training, 62.5% of the parents replied Not satisfied , so fire prevention facilities in taekwondo halls appeared inadequate. With regard to parents satisfaction with the cleanliness of the inside of taekwondo halls by gender, age, academic qualification, and the length of training, 36.4% of the parents replied Not Satisfied , so they appeared not satisfied with the cleanliness of the indoor environment of taekwondo halls. 3) Parents' satisfaction with the disposition and specialty of coaches (directors) With regard to parents' satisfaction with the kindness of coaches by gender, age, academic qualification, and the length of training, 89% of the parents replied positively. In addition replies to questions about coaches fairness, ***, leadership, *** and service spirit showed that most parents appeared to be satisfied with the coaches of taekwondo halls in terms of these characters. 4) Parents' satisfaction with management and educational aspects According to parents' replies to the question, Are trainees' problems well managed by the hall?, by gender, age, academic qualification, and the length of training. 36.4% of the parents were not satisfied, so the level of satisfaction was somewhat low. With regard to parents' satisfaction concerning the question, Did you receive a phone call for confirmation when ***', 20.1% of the parents answered 'No', so their satisfaction appeared to be somewhat low.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.

Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

The calyx of Fragaria ananassa (Rosaceae) has not been investigated for its chemical constituents and biological activity. This study focused on the isolation of active metabolites from the calyx of this plant. Compounds from F. ananassa calyx were extracted in 80 % aqueous MeOH and the concentrated extract was successively partitioned into EtOAc, n-BuOH, and $H_2O$ fractions. Repeated silica gel, octadecyl silica gel, and Sephadex LH-20 column chromatographies afforded six purified flavonoids. On the basis of spectroscopic methods, including $^1H$, $^{13}C$ nuclear magnetic resonance spectrometry (NMR), DEPT, and 2D NMR (gCOSY, gHSQC, gHMBC), the flavonoids were identified as kaempferol (1), astragalin (2), quercetin (3), isoquercitrin (4), sexangularetin (5), and sinensin (6). All the flavonoids were isolated for the first time from the F. ananassa calyx in this study. The flavonoids were evaluated for radical-scavenging capacity 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid ammonium salt), 2,2-diphenyl-1-picrylhydrazyl, and oxygen radical absorbance capacity methods. In conclusion, quercetin (3) consistently showed the highest ABTS, DPPH, and ORAC radical-scavenging activities compared with the other isolated flavonoids.

Lee, Seung-Su,Baek, Yoon-Su,Eun, Cheong-Su,Yu, Mi-Hee,Baek, Nam-In,Chung, Dae-Kyun,Bang, Myun-Ho,Yang, Seun-Ah Japan Society for Bioscience, Biotechnology, and A 2015 Bioscience, Biotechnology, and Biochemistry Vol.79 No.5

<P>Methanol extract of Zizania latifolia was partitioned with EtOAc, n-BuOH, and H2O. From the EtOAc layers, a new flavonolignan along with a known flavone and three known flavonolignans, tricin (1), salcolin A (2), salcolin B (3), and salcolin C (4), were isolated through repeated silica gel and ODS column chromatography. The chemical structure of the new flavonolignan was determined to be tricin-4'-O-[erythro-β-guaiacyl-(7-O-methyl)-glyceryl] ether and was named salcolin D (5) based on physicochemical and spectroscopic data, including FT-NMR and ESI-MS. All compounds were isolated for the first time from this plant. Compounds 2-5, tricin derivatives, all exhibited higher anti-inflammatory and anti-allergy activities than tricin. In particular, salcolin D (5) was shown to have the strongest inhibitory activity against LPS-induced NO production in RAW 264.7 cells as well as β-hexosaminidase release in IgE-sensitized RBL-2H3 cells. These results suggest that the presence of tricin derivatives conveys allergy and inflammation treatment ability to Z. latifolia.</P>
