Objectives: The purposes of this study are to investigate and analyze the status of reproductive tract infections (RTIs) in married women in rural western China, and to develop effective strategies for improving the ability of married women to prevent RTIs in this region.Methods: We conducted in-depth interviews of 142 married women from four villages in three townships. Two questionnaires were used to gather data on married women's health care status, family income, knowledge about RTIs, relevant behaviors, and attitudes toward RTIs. Descriptive, parallel, and logistic regression analyses and the Chi-square test were applied to analyze the relationships between basic conditions and several influential factors.Results: Over 80% of the respondents were of limited income and had with poor knowledge of and a lack of experience in preventing RTIs. Some 83.3% of the married women had experienced menstrual irregularities; 70.3% of those interviewed had experienced malodorous vaginal discharge with or without perineal itching. It was found that 80.7% of the interviewees did not have good personal hygiene habits in daily living regarding RTIs. It was found that the prevalence of RTIs was lower in women who had accurate information about RTIs. Most married women lacked basic knowledge of ways to prevent RTIs, and this, together with the limited support of the health care system and the absence of medical insurance schemes, was responsible for the observed high prevalence of RTIs.Conclusions: There is an urgent need to improve the capability of married women in rural China to prevent RTIs, and it is important to find effective ways to prevent these diseases. Three health promotion strategies are presently being implemented to prevent RTIs and to build capacity for disease prevention among married women in rural western China.

In recent years, like many people from other countries, the Chinese people pay close attention to nation’s development and policy of nuclear power, especially after the Fukushima incident. Furthermore, the concerns become exacerbated with the discussion about building the inland nuclear power plant. At the same time, the enthusiasm of the public participation which has its own characteristics has greatly improved in China. There is limited experience in the field of nuclear power decision-making in China. In this context, this paper comprehensive analyzes the Chinese public participation in decision-making of the nuclear power industry, summarizing the characteristics of public participation in this field. Then a typical case analysis with On-site visit and interview is made for verifying our theory. Based on these studies, some suggestions are put forward.

Agricultural residues from straw are widely used for energy and other applications. The thermal conductivity is one of the most important thermophysical properties considered when using agricultural residues, such as rice straw, in renewable energy engineering. In this paper, the thermal conductivity of rice straw was measured using a thermal probe by the transient hot wire method at selected moisture contents, temperatures and dry densities. The moisture contents of the samples ranged from 0 to 21.47 percent wet basis and the dry densities ranged from 90.7 to 136.4 kg/m3 and the temperature ranged from 0 to 170°C. Under those conditions, the thermal conductivity was measured and analyzed. Experiment results showed that the thermal conductivity increases with the increases of the density, moisture content and temperature, and the relationship among them is approximately described in a linear way. A new model to predict the thermal conductivity of agricultural residues from straw was proposed. The calculated results by the proposed model are in good agreement with the experimental data.

Carbonated hydroxyapatite (CHA) and hydroxyapatite (HA) were prepared by the wet chemical method. The contact angle was measured to calculate the surface energy. The biomineralization process in SBF solution of HA and CHA were investigated in vitro. The cell attachment and proliferation behavior of CHA and HA were compared by the cell culture experiments. The results show that the polar component of surface energy of B-type CHA is higher than that of HA. Osteoblastic cells attach and proliferate very well on the surface, which indicates the excellent cell compatibility. The CHA have high bioactivity owing to rapid formation of hydroxyl-carbonate-apatite (HCA) mineralized layer on the biomaterial’s surface in SBF.

A microelectronic packaging position detection method based on machine vision is proposed. Analyze the color and shape characteristics of the FC-D30 handle circuit boards, extract the R component. Complex background is removed through using image segmentation technology, this research utilizes image smoothing technology to eliminate the noise after segmentation. And use Sobel operator to do edge detection. The package position is detected by using image feature extraction techniques, and finally the position is located accurately. The experimental results show that, the average detection time of this algorithm is 180 milliseconds, the correct positioning is 99%. Microelectronic packaging position can be located fast and accurately by using machine vision technology, this mothod has a good theoretical and practical value.
