A down-scaled operational oceanographic system is developed for the coastal waters of Korea using a re- gional ocean modeling system （ROMS）. The operational oceanographic modeling system consists of at- mospheric and hydrodynamic models. The hydrodynamic model, ROMS, is coupled with wave, sediment transport, and water quality modules. The system forecasts the predicted results twice a day on a 72 h basis, including sea surface elevation, currents, temperature, salinity, storm surge height, and wave information for the coastal waters of Korea. The predicted results are exported to the web-GIS-based coastal informa- tion system for real-time dissemination to the public and validation with real-time monitoring data using visualization technologies. The ROMS is two-way coupled with a simulating waves nearshore model, SWAN, for the hydrodynamics and waves, nested with the meteorological model, WRE for the atmospheric surface forcing, and externally nested with the eutrophication model, CE-QUAL-ICM, for the water quality. The op- erational model, ROMS, was calibrated with the tidal surface observed with a tide-gage and verified with current data observed by bottom-mounted ADCP or AWAC near the coastal waters of Korea. To validate the predicted results, we used real-time monitoring data derived from remote buoy system, HF-radar, and geostationary ocean color imager （GOCI）. This down-scaled operational coastal forecasting system will be used as a part of the Korea operational oceanographic system （KOOS） with other operational oceanographic systems.

Duodenal perforation during endoscopic retrograde cholangiopancreatography(ERCP) is a rare complication,but it has a relatively high mortality *** diagnosis and prompt management are key factors for the successful treatment of ERCP-related *** management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire ***,the current standard treatment for duodenal free wall perforation is surgical ***,several case reports of endoscopic closure techniques using endoclips,endoloops,or fully covered metal stents have been *** describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral *** the cases were simply managed by endoclips under transparent capassisted *** on the available evidence and our experience,endoscopic closure was a safe and feasible method even for duodenoscope-induced *** results suggest that endoscopists may be more willing to use this treatment.

ZnO nanoparticles are widely used for the electron transport layers(ETLs)of quantum dots light emitting devices(QLEDs).In this work we show that incorporating fluorine(F)into the ZnO ETL results in significant enhancement in device electroluminescence stability,leading to LT50 at 100 cd m^(−2) of 2,370,000 h in red QLED,47X longer than the control devices.X-ray photo-electron spectroscopy,time-of-flight secondary ion mass spectroscopy,photoluminescence and electrical measurements show that the F passivates oxygen vacancies and reduces electron traps in *** photoluminescence versus bias measurements and capacitance-voltage-luminance measurements reveal that the CF4 plasma-treated ETLs lead to increased electron concentration in the QD and the QD/hole transport layer interface,subsequently decreasing hole accumulation,and hence the higher *** findings provide new insights into the critical roles that optimizing charge distribution across the layers play in influencing stability and present a novel and simple approach for extending QLED lifetimes.

Objective: The aim of this study is to explore the characteristic manifestations and contraindications of Xiaochaihu decoction(XD [It also stands for all the seven herbs in XD]) syndrome and to clarify the principle of using XD. Methods: By searching on the Encyclopedia of Traditional Chinese Medicine, 254 cases whose symptoms were relieved by XD and 48 cases who misused XD in ancient time were selected. Moreover, they are divided into two groups. Microsoft Excel 2016 was used as a storage tool. These two groups of cases were all treated with XD because of their similar manifestations, but therapeutic efficacies are reverse. The manifestations mislead doctors should be selected out to clarify the indications of using XD. Thus, the professional data mining software RapidMiner was used as a platform to do the frequent statistic and to create association rules between manifestations and herbs of both groups, respectively. After comparing the results of two groups, we can make a conclusion. Results: The characteristics of XD syndrome are alternative chills and fever, hypochondriac pain, and inflammatory swelling and pain(ear or breast). When any of these manifestations occur, XD can be used. Wiry pulse paired with alternative chills and fever, headache, thirst, or hypochondriac pain is also regarded as the indications of using XD. XD should not treat for fever paired with other manifestations, such as headache, delirium, or aversion to cold. In addition, the manifestations with high concurrence frequency do not mean the high correlation. Moreover, only according to the frequency, statistics cannot make correct conclusions. Conclusions:(1) XD is more fit for the excess syndrome such as excess fire in the liver or gallbladder meridians.(2) The medical records in which the XD is misused are also worth analyzing.(3) Association rules cannot be substituted with frequency statistics.

Revascularization of immature necrotic teeth is a reliable treatment alternative to conventional apexogenesis or apexification. In case 1, a 12-year-old boy had his necrotic, immature mandibular left second premolar treated with a revascularization technique. At a 24-month follow-up, periapical radiolucency had disappeared and thickening of the root wall was observed. In cases 2 and 3, a lO-year-old boy had his necrotic, immature, bilateral mandibular second premolars treated with the same modality. At 48-month （in case 2） and 42-month （in case 3） follow-ups, loss of periapical radiolucencies and increases in the root wall thickness were also observed.
