Carbon emissions from forest fires are considered an important factor of ecosystem carbon balance and global climate change. Carbon emissions from Japanese red pine stands （Pinus densiflora S. et Z.） burned by crown fire were estimated at Mt. Palgong in Daegu Metropolitan City, and crown fuel characteristics, including crown bulk density, crown base height, and fuel moisture content of Japanese red pine, were analyzed. Total biomass combusted was calculated by subtracting the biomass of burned stands from that of unburned stands exhibiting similar stand structures and site environments. Ten trees in the unburned area and five trees in the burned area were cut by using direct harvesting techniques to estimate crown layer biomass. All biomass sampled was oven-dried and weighed. The dry weight ratios of stems, branches, and needles were 7o%, 21%, and 9%, respectively. The available fuel load susceptible to combustion during the crown fire spread was equivalent to 55% of the crown layer biomass. The crown bulk density was 0.24 kg/m3 on average. The estimated amount of CO2 was 23,454 kg CO2/ha for the crown layer. These results will be useful for calculating the amount of CO2 emitted from forest fires and for developing a forest carbon model in P. densiflora forests.

A flexible copper clad laminate(FCCL) was fabricated using electroless-and electro-Cu plating processes and the effects of pre-treatment time on the adhesion strength of the FCCL were evaluated based on interfacial *** neutralization and catalyst time were varied in the range of 0-20 min and 0.1-10 min,respectively,and the interfacial condition of the FCCL was characterized by atomic force microscopy(AFM) and X-ray photoelectron spectroscopy(XPS).It is observed that the peel strength increases significantly as the neutralization and catalyst time *** strength as high as 7.2-7.3 N/cm is obtained as the neutralization and catalyst time increase up to 20 min and 10 min,respectively,which is comparable to the strength achieved by the conventional laminating and sputtering *** improvements are probably due to an increase in the surface roughness of polyimide(PI),the activated surface condition,and the adsorption of palladium ions/atoms(Pd) on the PI surface which act as nucleation sites for Cu.

AIM: To investigate the cytotoxicity, anti-inflammatory activity, and action mechanism of root bark extracts of Acanthopanax henryi. METHOD: The hot methanol extract of the root bark of A. henryi was subjected to XAD-4 column chromatography eluting with a gradient of methanol in water. The cytotoxicity and anti-inflammatory effects of the MeOH fractions were evaluated on the inhibition on lipopolysaccharide(LPS)-induced nitric oxide, prostaglandin E2, interleukin-1β, and interleukin-6 production in RAW 264.7 macrophages. RESULTS: The 80% MeOH fraction was a better inhibitor of LPS-induced NO, PGE2, IL-1β, and IL-6 production, and expression of inducible nitric oxide synthase(iNOS) at the protein levels in a concentration-dependent manner. CONCLUSION: The 80% MeOH fraction of A. henryi root bark has significant anti-inflammatory activity. This provides a pharmacological basis for clinical application for the treatment of inflammation.

Herein, we report a new and simple method for the preparation of metallic copper nanospheres- decorated cellulose nanofiber composite （CuNSsJCNFs）. Initially, the cellulose acetate nanofibers （CANFs） were electrospun followed by deacetylation and anionization to produce functional anionic cellulose nanofibers ff-CNFs）. The CuCl2 precursor was deposited on thef-CNFs （CuC12/CNFs） by a simple dipping method. Then the CuCIdCNFs were reduced under vacuum by using aluminum foil to produce the CuNSs/ CNFs. The resultant CuNSs/CNFs composite was characterized by various microscopic and spectroscopic methods. Fourier transform infrared spectroscopy （FT-IR） confirmed the successful functionalization of anionic groups with the CNFs. The field emission scanning electron microscopy （FE-SEM） and transmission electron microscope （TEM） results confirmed the formation of CuNSs on the surface of CNFs. From the scanning electron microscopy-energy dispersive spectroscopy （SEM-EDS） analysis, the weight percentage of Cu was found to be 23.5 wt%. The successful reduction of CuO to metallic Cu was confirmed by X-ray photoemission spectroscopy （XPS） and X-ray diffraction （XRD） analyses. Mechanism has been proposed for the formation of metallic Cu sphere on CNFs.

High energy ball milling （HEBM） method was applied to synthesize Ni （OH）2 with different doped elements sub-stitution for Ni^2＋. The morphology, structure and electrochemical behavior of prepared powders were studied. The re-suits reveal that all the synthesized Ni（OH）2 particles were in sub-micron sizes and greatly agglomerated. Co-, Mg-,Fe- or Mn-doped Ni （OH） 2 was of β-phase with 0.400-0.500 nm crystal interlayer distance, while A1- and Zn-doped products displayed a-phase with larger crystal interlayer spaces. The electrochemical mechanisms of synthe-sized Ni（OH）2 electrodes were discussed by EIS spectra. The specific capacity of Co-doped Ni （OH）2 is 245 mA·h · g^-1, i. e. , 60 mA· h · g^-1 higher than that of Al-doped electrode, which has the highest discharging plat-form of a mid-voltage of 1.30 V.
