The article introduces operation management and mode of human resources market in henna, also puts forward Henan talent market management problems and gives some management countermeasures.

Abstract: A control method based on genetic neural network is presented to deal with the nonlinear object of the high-power PS-FB-ZVS PWM DC/DC converter. The control system optimizes the initial weight of the BP neural network and PID parameters tuning on line utilizing the genetic algorithm, which directly controls the object in closed-loop and has solved the problem that the controller network initial weight coefficient influences the control effect, thus, the optimal dynamic and steady state performance of the system is ensured. In the MATLAB environment, the control systems consisting of different controllers are simulated, and the output voltage and output current waveforms are obtained when the system is loaded by experiment. The results show that the controller has strong robustness, fast response speed, and small output voltage fluctuations with load changes.

Abstract: The curriculum development is the core task of the current teaching reform of higher vocational schools in China. The curriculum development for the higher vocational education is a complicated systematic project. With the software technology major in Taizhou Vocational & Technical College as its background, according to the curriculum development theory based on work process, this paper first analyzes the basic methods of curriculum development, and then researches on the curriculum development technologies for software technology major in higher vocational schools from the four aspects of work task analysis, typical work integration, curriculum system construction and curriculum teaching implementation, and designs a specific implementation process. Practice shows that the proposed method of curriculum development in this paper has strong operability and obvious implementation results, which provides curriculum reform for the software technology major in higher vocational schools in China with a significance of reference.

Abstract: Land subsidence in Cangzhou of the North China Plain, has been an ongoing problem for the past four decades (since the later 1970s). With the development of new synthetic aperture radar(SAR)sensors and interferometric synthetic aperture radar(InSAR) techniques, the application of satellite Radar data have enhanced capabilities to detect and monitor ground displacements with centimeter to millimeter precision at greater spatial detail and higher temporal resolution. We use Permanent Scatterers interferometric synthetic aperture radar（PS-InSAR）technology (Hooper, A.2004) to detect and measure ground movement in this area（from2004 to 2007）. Results of the cangzhou region study are reported and the utility of the InSAR methodology is discussed.

Abstract: This paper introduces the OLSR routing protocol,IPv4 and IPv6 address protocol's characteristics and internal mechanism.Through simulation, we will see the performance of OLSR routing protocol based on IPv4 and IPv6 address protocol.Experiments show that less HELLO message and TC message will need and smaller jitter will get while using the OLSR routing protocol based on IPv6.But bigger delay and smaller throughput will appear compared with OLSR routing protocol based on IPv4 address protocol.

Abstract: The thesis makes a study on the experience as to the location and three-dimensional rural service of Yiyang Vocational and Technical College, so as to elaborate for reference the following fields including not only site selection and agricultural service, but also measures concerning the promotion of agricultural-related subjects, higher vocational college students, rural entrepreneurial talented persons, new migrant workers’ training, agricultural technical service and so forth.

Abstract: Coagulase-negative staphylococci (CNS) are among the most frequently isolated bacterial species in clinical microbiology, and most CNS-related infections are hospital acquired. The aim of the present study was to evaluate the antibiotic resistance profiles of CNS isolated in the First Bethune Hospital. Disk diffusion method was used to study the antimicrobial resistance. The data were analyzed by WHONET 5 software according to Clinical and Laboratory Standards Institute (CLSI). The majority of 2484 strains of CNS were collected from blood (925, 37.2%), secretions (652, 26.2%) , urine (323, 13.0%) and pus (250, 10.1%). The percentage of methicillin-resistant coagulase-negative Staphylococci (MRCNS) was 80.5％. All the CNS isolates were sensitive to vancomycin and teicoplanin. MRCNS strains were frequently resistant to multiple antibiotics. Antimicrobial resistance of MRCNS was more serious than that of methicillin-sensitive coagulase-negative Staphylococci (MSCNS). These results suggest that surveillance of antimicrobial resistance among CNS is necessary.

Abstract: Citrobacter freundii is important causes of nosocomial infections. The present study aimed to evaluate the antibiotic resistance profiles of Citrobacter freundii isolated from the First Bethune Hospital. Disk diffusion method was used to study the antimicrobial resistance. The data were analyzed by WHONET 5 software according to Clinical and Laboratory Standards Institute (CLSI). The majority of 432 strains of Citrobacter freundii were collected from sputum (240, 55.6%), secretions and pus (85, 19.7%), blood (58, 13.4%). All the Citrobacter freundii isolates were sensitive to imipenem and meropenem. Citrobacter freundii strains were frequently resistant to multiple antibiotics. The results suggest that surveillance of antimicrobial resistance in Citrobacter freundii is necessary.

Abstract: Klebsiella spp. are opportunistic pathogens which frequently cause community and nosocomial infections. The present study aimed to evaluate the antibiotic resistance profiles of Klebsiella spp. isolated from the First Bethune Hospital. Disk diffusion method was used to study the antimicrobial resistance. The data were analyzed by WHONET 5 software according to Clinical and Laboratory Standards Institute (CLSI). The majority of 3149 strains of Klebsiella spp. were collected from sputum（1890, 60.0%），blood（378, 12.0%） and secretions（315, 10.0%）. The percentage of extended-spectrum β-lactamases (ESBLs) in Klebsiella spp. was 53.8% (1694/3149). Klebsiella spp. strains were frequently resistant to multiple antibiotics. Antimicrobial resistance of ESBL-producing Klebsiella spp. was more serious than that of non-ESBL-producing isolates. The results suggest that surveillance of antimicrobial resistance in Klebsiella spp. is necessary.

Abstract: In order to enhance the efficiency and the level of instruments management in colleges and universities, the management system of instruments sharing based on RFID technology has been designed, developed and brought into operation. Automation and intelligentization of lots of work have been achieved such as user authentication of instruments, open reservation of instruments, charge and sharing of instruments, real-time management of laboratory, settlement of expenditure and benefit evaluation, promoting the open sharing of instruments in colleges and universities.
