In this study,a tropical cyclogenesis detection system,Tropical Cyclone Analysis&Forecast(TCAF),was evaluated with an operational numerical model of the Korea Meteorological Administration(KMA).The tracking performance was compared with the result with the ECMWF model input field(TCAF-ECMWF).In order to improve the performance,different tracking time at an interval of 6 hours were *** lowest false alarm rate and the highest hit rate(correct detection)were achieved at 06 hour after the initial tracking *** tracking performance was also tested on two typhoons in 2013,LEEPI(1304)and DANAS(1324).The results showed that the TCAF-ECMWF detected tropical depressions 72 hours before the formation of the typhoon DANAS,which is a 12-hour earlier detection compared with the current performance with the use of KMA’s numerical weather prediction(NWP)model ***,it is expected that TC genesis detection could be improved by determining an optimal tracking time and by using more accurate NWP model data.

Aim： To investigate whether the biological process of superparamagnetic iron oxide （SPIO）-labeled human mesenchymal stem cells （hMSCs） may be monitored non-invasively by using in vivo magnetic resonance （MR） imaging with conventional 1.5-T system examinations in corpus cavernosa of rats and rabbits. Methods： The labeling efficiency and viability of SP10-labeled hMSCs were examined with Prussian blue and Tripan blue, respectively. After SPIO-labeled hMSCs were transplanted to the corpus cavernosa of rats and rabbits, serial T2-weighted MR images were taken and histological examinations were carried out over a 4-week period. Results： hMSCs loaded with SPIO compared to unlabeled cells had a similar viability. For SPIO-labeled hMSCs more than lx 105 concentration in vitro, MR images showed a decrease in signal intensity. MR signal intensity at the areas of SPIO-labeled hMSCs in the rat and rabbit corpus cavernosa decreased and was confined locally. After injection of SPIO-labeled hMSCs into the corpus cavernosum, MR imaging demonstrated that hMSCs could be seen for at least 12 weeks after injection. The presence of iron was confirmed with Prussian blue staining in histological sections. Conclusion： SP10-labeled hMSCs in corpus cavernosa of rats and rabbits can be evaluated non-invasively by molecular MR imaging. Our findings suggest that MR imaging has the ability to test the long-term therapeutic potential of hMSCs in animals in the setting of erectile dysfunction.

The aim of present study was to assess the effects of a eutectic mixture of topical anesthetics (EMLA cream) on pain responses of preschoolers during venipuncture. The pain responses were reported by children, nurses, and the children’s mothers. The pre- and post-test-designed study, which included a non-equivalent control group, was carried out in a pediatric unit at E University Hospital in South Korea. Pain responses during venipuncture were measured by the self-reporting of the children using the Face Pain Rating Scale (FPRS), the Procedure Behavior Checklist by nurses (PBCL), the Visual Analog Scale (VAS) by mothers, in addition to measurements of the children’s pulse rate and level of oxygen saturation. EMLA cream was effective in decreasing the pain responses of the children as assessed by FPRS, PBCL, and VAS scores. However, pulse rate and level of oxygen saturation of the children during venipuncture were not significantly different between the two groups. EMLA cream could be a useful option for reducing pain in preschool children during invasive procedures.

We examined the changes in numerous skin conditions before and after the ap-plication of interferential current therapy to various regions of healthy male bodies. In this study, we assessed the differences in the skin’s sebum, moisture levels, pores, wrinkles, pigmentation, and elasticity on the shoulders, lower back, and the knees of Korean males in their 20s. A total of 30 healthy males were in-cluded in the study. We used a skin diagnosis meter as a device for measuring the state of the skin. A statistical difference was found when comparing the pre- and post-measurement values in regards to the moisture levels, wrinkles, and pig-mentation. In the correlation analysis results, the sebum and pigmentation, moisture levels and wrinkles, moisture levels and pigmentation, and moisture levels and elasticity were all positively correlated, respectively. The results of this study partially suggest that a change in skin condition is associated with ex-ternal stimulation. The study also found that the effects of the application of in-terferential current therapy on the various skin conditions may differ depending on the region of the body that the application is conducted as well.

Osteoporosis is a highly prevalent public health burden associated with an increased risk of bone fracture, particularly in aging women. Estrogen, an important medicinal component for the preventative and therapeutic treatment of postmenopausal osteoporosis, induces osteogenesis by activating the estrogen receptor signaling pathway and upregulating the expression of osteogenic genes, such as bone morphogenetic proteins(BMPs). The epigenetic regulation of estrogen-mediated osteogenesis,however, is still unclear. In this report, we found that estrogen significantly induced the expression of lysine-specific demethylase 6B(KDM6B) and that KDM6B depletion by shRNAs led to a significant reduction in the osteogenic potential of ***, upon estrogen stimulation, estrogen receptor-α(ERα) was recruited to the KDM6B promoter, directly enhancing KDM6B expression. Subsequently, KDM6B was recruited to the BMP2 and HOXC6 promoters, resulting in the removal of H3K27me3 marks and activating the transcription of BMP2 and HOXC6, the master genes of osteogenic differentiation. Furthermore, we found that estrogen enhanced DMSC osteogenesis during calvarial bone regeneration and that estrogen’s pro-osteogenic effect was dependent on KDM6B in vivo. Taken together, our results demonstrate the vital role of the ERα/KDM6B regulatory axis in the epigenetic regulation of the estrogen-dependent osteogenic response.
