-This paper deals with the active and reactive power control of Grid connected system. It was shown that active power and reactive power can be dependently controlled with two individually adaptable parameters. The two parameters are power angle and voltage magnitude. Transient state will occur with active or reactive power reference value variation. This paper presents a new control strategy for active and reactive power control of less interaction and improved transient response. The paper details the control technique by the mathematical and electrical network analysis of the methodology. The performance was verified through computer simulation using MATLAB Simulink and experiment.

Background: This study investigated the effects of Vipera lebetina turanica snake venom (SV) on cerebral infarction induced by middle cerebral artery occlusion in mice. Methods: Following cerebral infarction, SV was injected intravenously or added to BV2 cell culture. Tissue injury was detected using triphenyltetrazolium chloride (TTC) staining, neurological deficit score, NO, ROS, and GSH/GSSG assays, qPCR, Western blot, and cell viability. Results: Cerebral infarction caused by middle cerebral artery occlusion as observed by TTC staining, showed SV inhibited cell death, reducing the number of brain cells injured due to infarction. SV treatment for cerebral infarction showed a significant decrease in abnormal behavior, as determined by the neurological deficit score. The oxidation and inflammation of the cells that had cerebral infarction caused by middle cerebral artery occlusion (NO assay, ROS, GSH/GSSG assay, and qPCR), showed significant protection by SV. Western blot of brain infarction cells showed the expression of iNOS, COX-2, p-IkB-α, P38, p-JNK, pERK to be lower in the SV group. In addition, the expression of IkB increased. BV2 cells were viable when treated with SV at 20 μg/mL or less. Western blot of BV2 cells, treated with 0.625, 1.5, 2.5 μg/mL of SV, showed a significant decrease in the expression of p-IkB-α, p-JNK, iNOS, and COX-2 on BV2 cells induced by LPS. Conclusion: SV showed anti-inflammatory and anti-oxidant effects against cerebral infarction and inflammation.

The aim of this study was to compare the effects of different cupping therapy methods combined with Korean medicine treatments for peripheral facial paralysis. Methods: 105 patients treated for peripheral facial paralysis with cupping therapy and other Korean medicine treatment at Gil Korean medicine hospital, Gachon University between May 19, 2014 and June 30, 2018 were selected and their medical charts retrospectively analyzed. 48 patients who met the inclusion criteria were divided into 2 groups: wet cupping (WC) therapy, or dry cupping (DC) therapy combined with Korean medicine treatment. The duration of treatment ranged from 2 weeks for inpatient treatment to 2 months for outpatient treatment. Both WC and DC therapy were performed on TE13, 3 times per week during the treatment period. The effect of cupping therapy was evaluated by using the Gross Grading System of the House-Brackmann (HB score) and the Yanagihara's Unweighted Grading System (Y score). Results: For both WC and DC treatment of symptoms related to peripheral facial paralysis, HB scores showed a significant decrease and Y scores showed a significant increase from baseline to end of treatment, indicating a beneficial improvement in patient symptoms for both WC and DC. Conclusion: In this study, both DC and WC treatment had significant improvements on peripheral facial paralysis symptoms, with WC having significantly greater beneficial effects than DC.
