The objective of this paper is to present an and promote the capabilities of organizational portfolio ment Maturity Model （ OPM3 ）, the process areas of approach to comprehensively and quantitatively evaluate management. Based on the Organizational Project Manage- organizational project portfolio management are identified through the questionnaire survey and further analysis, and five capability levels are put forward and described. Then the methods of Delphi, AHP and multi-layer fuzzy comprehensive evaluation are applied to construct a mod- el of assessment and promotion. Finally, an illustrative example is presented to verify the proposed approach The result objectively and accurately describes the project portfolio management capabilities of the organization, and shows that it is able to provide a theoretical basis for an organization to improve and enhance the project port- folio management

The ＇double T-DNA＇ binary vector p13HSR which harbored two independent T-DNAs, containing hygromycin phosphotransferase gene （hpf） in one T-DNA region and three target genes （hLF, SB401, RZ10） in another T-DNA region, was used to generate selectable marker-free transgenic rice by Agrobacterium-mediated transformation. The regenerated plants with both the three target genes and the selectable marker gene hpt were selected for anther culture. RT-PCR analysis indicated that target genes were inserted in rice genomic DNA and successfully transcribed. It took only one year to obtain double haploid selectable marker-free transgenic plants containing the three target genes with co-transformation followed by anther culture technique, and the efficiency was 12.2%. It was also noted that one or two target genes derived from the binary vector were lost in some transgenic rice plants.

This study constructs a Green Mining model based on identification and analysis of the four key driving factors of Green Mining in coal mining enterprises in China. Twelve research propositions are raised and empirically tested by using Structural Equation *** result shows that four key factors affect the intended implementation of Green Mining by improving a corporations efficiency and reputation. The diffusion of Green Mining technology has direct positive influence on the intended Green Mining implementation; Stakeholders' green appeal has a positive influence on the decision makers' attitude and values. The empirical study provides support for the government to establish a reasonable regulation and control mechanism to improve enterprises' enthusiasm for Green Mining. Four Green Mining incentive policies are raised to regulate and motivate the coal mining enterprises to improve their environmental behaviors. The government can adopt piece(s) of them to change the enterprises' roles from traditional passive to modern initiative.

Objective： To review literature from 1954 to 2007 and explore the regularity of point *** and methods for acupuncture-moxibustion treatment of cerebral palsy. Methods： A comprehensive analysis was made by a method of metrological analysis according to the data from ＂China Modem Acupuncture-moxibustion Information Databank＂. Results： Points Zusanli （ST 36）, Quchi （LI 11） and Hegu （LI4） were most frequently used. Head points Baihui （GV 20） and sishencong （Ex-HN1） were also frequently used. Acupuncture, scalp acupuncture and acupuncture point injection were the major treatments. Conclusion： Acupuncture intervention can improve the therapeutic effect on cerebral palsy. It is suggested that Baihui （GV 20）, sishencong （Ex-HN1）, Zusanli （ST36）, Quchi （LI11） and Hegu （LI4） be selected as a basic prescription for acupuncture-moxibustion treatment of cerebral palsy.

Based on a Life Cycle Assessment model, the effect of the whole life cycle of excessive commodity packaging on the environment was analyzed by eBalance Evaluation LCA software from production through circulation. The cost evaluation system and environment impact model of its three main processes, that is, material production, product machining and waste manufacturing, were established to identify the main environmental impact corresponding indicators and the influence on energy conservation and emissions reduction of excessive packaging life cycle. And packaging of moon-cakes was taken as an example to analyze the difference between the ordinary packaging and excessive packaging of moon-cakes in terms of life cycle assessment and costs analysis. Meanwhile some measures are put forward to conserve energy and reduce emissions.

In this study, a hybrid process using non‐thermal plasma (NTP) and photocatalytic oxidation (PCO) was adopted for the degradation of gas‐phase toluene using TiO2 as the photocatalyst. To discover the synergetic effect between NTP and PCO, the performances of both sole (O3, UV, NTP, and PCO) and combined (O3 + TiO2, O3 + UV, NTP + UV, O3 + PCO, and NTP + PCO) processes were investigated from different perspectives, such as the toluene removal efficiency, selectivity of COx, mineralization rate, ozone utilization, and the generation of by‐products. The toluene removal efficiency of the combined NTP + PCO process was 80.2%, which was much higher than that of a sole degradation process such as NTP (18.8%) and PCO (13.4%). The selectivity of CO2 and the ozone utilization efficiency also significantly improved. The amount of by‐products in the gas phase and the carbon‐ based intermediates adsorbed on the catalyst surface dramatically reduced. The improvement in the overall performances of the combined NTP + PCO process was mainly ascribed to the efficient utilization of ozone in the photocatalytic oxidation, and the ozone further acting as an electron acceptor and scavenger, generating more hydroxyl radicals and reducing the recombination of electron‐ hole pairs.
