Objective:To investigate the anti-obesity activity and the action mechanism of the roots of Adenophora triphylla *** extract(ATE) in high-fat diet(HFD)-induced obese mice and 3T3-LI ***:The roots of Ademption triphylla were extracted with 70%*** demonstrate the compounds,linoleic acid was analyzed by using gas chromatography:and the anti-obesity effects and possible mechanisms of ATE were examined in 3T3-L1 adipocytes and HFD-induced obese ***:Treatment with ATE inhibited the lipid accumulation without cytotoxicity in 3T3-L1 ***,200 and 400 mg/kg ATE treatment significantly decreased the body weight gain,white adipose tissues(WATs) weight and plasma triglyceride level,while 100 and 200 mg/kg ATE treatment increased the plasma high-density lipoprotein cholesterol level in the HFD-induced obese mice,as compared with the HFD *** with 200 and 400 mg/kg ATE also lowered the size of adipocytes in adipose tissue and reduced the lipid accumulation in *** treatment showed significantly lower expression level of adipogenesis-relatcd proteins,such as peroxisome proliferator-activated receptor y,fatty acid binding protein(aP2),fatty acid synthase in 3T3-L1 adipocytes;and furthermore,decreased peroxisome proliferatoractivated receptor γ,aP2,fatty acid synthase,sterol regulatory element binding protein-1c,and lipoprotein lipase mRNA expression levels in WAT of the HFD-induced obese ***:These results suggested that the ATE has an anti-obesity effect,which may be elicited by regulating the expression of adipogenesis and lipogenesis-related genes and proteins in adipocytes and WAT of the HFD-induced obese mice.

The aim of this study was to estimate fine root production （FP） and fine root mortality （FM） at 0-10, 10-20, and 20-30 cm soil depths using minirhizotrons in a 75-year-old Pinus densiflora Sieb. et Zucc. forest located in Gwangneung, Korea. We developed the conversion factors （frame cm-2） of three soil depths （0.158 for 0-10 cm, 0.120 for 10-20 cm, and 0.131 for 20-30 cm） based on soil coring and minirhizotron data. FP and FM were estimated using conversion factors from March 26, 2013 to March 2, 2014. The annual FP and FM values at the 0-30 cm soil depth were 3200.2 and 2271.5 kg ha-1 yr -1, respectively. The FP estimate accounted for approximately 17 % of the total net primary production at the study site. FP was highest in summer （July 31-September 26）, and FM was highest in autumn （September 27-November 29）. FP was positively correlated with seasonal change in soil temperature, while FM was not related to that change. The sea- sonality of FP and FM might be linked to above-ground photosynthetic activity. Both FP and FM at the 0-10 cm depth were significantly higher than at 10-20 and 20-30 cm depths, and this resulted from the decrease in nutrient availability with increasing soil depth. The minirhizotron approach and conversion factors developed in this study will enable fast and accurate estimation of the fine root dynamics in P. densiflora forest ecosystems.

As the increasing number of Phasor Measurement Units(PMUs) are deployed, wide area protection in power systems has been gaining interest. In particular, fault detection, fault classification and fault area estimation are essential to reduce the damage of faults, and even prevent catastrophic cascades of failures. In this paper, we present a scheme for fault area estimation using PMUs and traveling wave theory. The purpose of this paper is to formulate a scheme for fault area estimation by calculating the approximate fault location based on traveling wave *** research has targeted at reliable operation of wide transmission system through the estimation of fault *** verify the suggested scheme, the various simulations are performed in practical Korean power transmission *** simulation results show that the proposed scheme has a good performance with high accuracy for estimating fault area.
