( An Cheng Yin ),( Xin Yu Wang ),( Dong Liu ),( Yan Yun Zhang ),( Mei Xia Yang ),( Li Juan Li ),( Li Song Wang ) 한국균학회 2019 Mycobiology Vol.47 No.4
Two new species of the lichen genus Placolecis are discovered in China, namely P. kunmingensis An. C. Yin & Li S. Wang and P. sublaevis An. C. Yin & Li S. Wang. The new combination P. loekoesiana (S.Y. Kondr., Farkas, J.J. Woo & Hur) An. C. Yin is proposed. Placolecis kunmingensis is characterized by having simple, spherical or ellipsoid, hyaline spores, and pear-shaped pycnidia; while P. sublaevis can be distinguished by its thallus forming larger aggregations with slightly flattened lobes at the thallus margin, and urn-shaped pycnidia. Descriptions, a phylogenetic tree and a key are provided for all the known Placolecis species in China.

Purpose: To compare tumor size by mammography and sonography and align with pathological results in primary breast cancer cases. Materials and Methods: We retrospectively reviewed 95 primary breast cancer patients who underwent mammography and sonography from January 2011 to June 2012. The largest tumor diameter was chosen as sizing reference for each imaging modality. The measurements of mammography and sonography were considered concordant if they were within the measurement of pathological results ${\pm}0.5cm$. Pearson's correlation coefficient was calculated for imaging results. Results: The range of the maximum diameter was 0.6cm-10.5cm and mean value was $3.81{\pm}2.04cm$ by pathological results, 0.7cm-12.4 cm and $3.99{\pm}2.19cm$ by mammography, and 0.9cm-11.0cm and $3.63{\pm}2.01cm$ by sonography, respectively. Sonography (R: 0.754), underestimated tumor size, but had a better correlation with pathological tumor size compared to mammography (R: 0.676), which overestimated tumor size. Conclusions: Sonography is superior to mammography in assessment of primary breast cancer.

Background: Acupuncture has been widely utilized for irritable bowel syndrome (IBS). However, heterogeneity is large among therapeutic strategies and protocols. The aim of this study was to propose some down-to-earth recommendations and establish an optimized protocol for acupuncture practice in IBS. Methods: A panel of 74 traditional Chinese medicine (TCM) acupuncturists participated in clinical issue investigation. Subsequently, systematic reviews concerning acupuncture for IBS were screened within 3 databases. An initial consensus questionnaire was formed from the results of clinical issue investigation and literature review. Ultimately, a Delphi vote was carried out to determine these issues. 30 authoritative experts with extensive experience were requested to respond with agreement, neutrality, or disagreement for the items. Consensus achievement on a given item was defined as greater than 80% agreement. Results: Following a 2-round Delphi survey, there were 19 items reaching consensus; of which 5 items (26.32%) achieved thorough consensus, and significant agreement was reached for the other 14 items. These items can be classified into the 3 major domains: 1) clinical outcomes that acupuncture can bring for favorable intervention population (5 items), 2) suitable therapeutic principles and parameters of acupuncture (13 items), 3) possible adverse events in the treatment (1 item). Conclusion: Without any ready-made guidelines and lacking of homogeneity in the published literatures, such expert consensus could be valuable for TCM acupuncturists in daily practice and patients with IBS to obtain appropriate and standardized acupuncture treatment. In addition, it also points out the clinical focus which need to be further explored in future trials.

Xin Yu Wang,Yogesh Joshi,Jae Seoun Hur The Korean Society of Mycology 2011 Mycobiology Vol.39 No.1
Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

Currently, taxol is mainly extracted from the bark of yews; however, this method can not meet its increasing demand on the market because yews grow very slowly and are a rare and endangered species belonging to first-level conservation plants. Recently, increasing efforts have been made to develop alternative means of taxol production; microbe fermentation would be a very promising method to increase the production scale of taxol. To determine the activities of the taxol extracted from endophytic fungus N. sylviforme HDFS4-26 in inhibiting the growth and causing the apoptosis of cancer cells, on comparison with the taxol extracted from the bark of yew, we used cellular morphology, cell counting kit (CCK-8) assay, staining (HO33258/PI and Giemsa), DNA agarose gel electrophoresis and flow cytometry (FCM) analyses to determine the apoptosis status of breast cancer MCF-7 cells, cervical cancer HeLa cells and ovarian cancer HO8910 cells. Our results showed that the fungal taxol inhibited the growth of MCF-7, HeLa and HO8910 cells in a dose-and time-dependent manner. IC50 values of fungal taxol for HeLa, MCF-7 and HO8910 cells were $0.1-1.0{\mu}g/ml$, $0.001-0.01{\mu}g/ml$ and $0.01-0.1{\mu}g/ml$, respectively. The fungal taxol induced these tumor cells to undergo apoptosis with typical apoptotic characteristics, including morphological changes for chromatin condensation, chromatin crescent formation, nucleus fragmentation, apoptotic body formation and G2/M cell cycle arrest. The fungal taxol at the $0.01-1.0{\mu}g/ml$ had significant effects of inducing apoptosis between 24-48 h, which was the same as that of taxol extracted from yews. This study offers important information and a new resource for the production of an important anticancer drug by endofungus fermentation.
A Video Traffic Flow Detection System Based on Machine Vision
Wang, Xin-Xin,Zhao, Xiao-Ming,Shen, Yu Korea Information Processing Society 2019 Journal of information processing systems Vol.15 No.5
This study proposes a novel video traffic flow detection method based on machine vision technology. The three-frame difference method, which is one kind of a motion evaluation method, is used to establish initial background image, and then a statistical scoring strategy is chosen to update background image in real time. Finally, the background difference method is used for detecting the moving objects. Meanwhile, a simple but effective shadow elimination method is introduced to improve the accuracy of the detection for moving objects. Furthermore, the study also proposes a vehicle matching and tracking strategy by combining characteristics, such as vehicle's location information, color information and fractal dimension information. Experimental results show that this detection method could quickly and effectively detect various traffic flow parameters, laying a solid foundation for enhancing the degree of automation for traffic management.
A Comparative Study of Camouflage Printing Color Matching Based on Monitor and Paper Card
Yu-wen Wang,Qing-zhu Yi,Yi Ding,Guang-xin Wu,Jing-bin Zhang,Ni Wang 한국섬유공학회 2021 Fibers and polymers Vol.22 No.4
To improve the accuracy of color reproduction for camouflage printing, a new color matching method, namedmonitor-paper-fabric, was proposed by importing color management into textiles, which matched the printing pastesaccording to the color of the paper card printed by the ink-jet printer after color management. Not like the traditional colormatching method, it matched the printing pastes according to the color from computer monitor after color correction. Twocolor matching methods were analyzed by comparing the color difference. It was found that the “monitor-paper-fabric” colormatching method could be considered as a convenient and feasible color matching method. Most color differences betweenthe monitor and the fabric in the camouflage pattern were reduced to lower than 4, except for color blocks 5 and 6. Inaddition, the color differences of six color blocks between the paper and the fabric were all less than 3.5, and were lower thanthose between the monitor and the fabric. The color consistency between the paper and the fabric was better than thatbetween the monitor and the fabric.
