ABSTRACT
Objective:To lay a foundation for the continuous improvement of the birth cohort management in the future, and provides references for other hospitals in establishing the birth cohort through sharing the practice, experience and reflection of the establishment and management of the birth cohort of 500, 000 pregnant women.Methods:The present situation and data of the establishment and management of the birth cohort of 500, 000 pregnant women were summarized to describing the practice, experience and reflection.Results:The specific work regarding the establishment and management of the cohort include personnel investment, standards development, implementation process and quality control. Three phases of the management experiences were summarized which including explorative process implementation; standardize project implementation, and quality improvement along with the fast development of the birth cohort. Generally, the attention of leadership was one of the most important factors for the establishment and management of birth cohort in each research site.Conclusions:It is important that comprehensive considerations of factors including the personnel, standards, practical management process, quality control and the attention of leadership plays important role in improving the quality and efficiency of birth cohort establishment and management.
ABSTRACT
Objective To develop the management system of science and technology awards through understanding dynamically the trend of awards in Beijing Obstetrics and Gynecology Hospital,Capital Medical University.Methods The data from the department of science and technology in Beijing Obstetrics and Gynecology Hospital,Capital Medical University were used to learn about some informations of science and technology awards including the winner's age,education,title and department,the proportion of rank and level,the trend of awards from 1998 to 2017,the number of social association awards from 2013 to 2017.Results The kinds of science and technology awards were up to 11.The 23 awards were obtained from 1998 to 2017,which were mainly composed of social association awards (65％) and gave priority to the second rank (48％).The age of the first winners were from 51 to 55 years.There were 9 departments obtained awards,accounting for 45％ of all the hospital clinical medical department.The increasing trend in the number of awards were observed from 1998 to 2017,and in nearly five years,the number showed the fast rising trend.Conclusions The less number of awards were obtained in Beijing Obstetrics and Gynecology Hospital,Capital Medical University.Whereas the most of awards were supported by social association.We were lack of the high rank and high level awards.The higher age showed that there were not enough youth scientific research and talent reserves.The situation need to be further strengthened the management and promoted the development in science and technology awards.
ABSTRACT
Objective Along with the fast increasing of scientific research capacity,more and more financial funding were available at hospital level,at the same time,the kinds and quantities of the reagents and consumables for scientific research uses are also increased.As a result,procurement risks become a gig concern in hospitals.Thus,how to increase the cost-effectiveness of their financial funds while lowering the risks and hidden troubles are the key issues need addressing urgently.Methods This paper took Beijing Obstetrics and Gynecology Hospital,Capital Medical University as an example,summarized its service conditions of reagents and consumables for scientific research uses in past three years (2014-2016),according to the comparison and analysis of their actual prices with the guiding prices on the same as indicated on the informational procurement platform,to discuss the existing issues and risks.Results Under the current procurement management system of reagents and consumables for scientific research uses,the purchasing price for some items are relatively high.Conclusions This paper specifically proposed some measures and advices on risk prevention and control during the period of transition with the intention to reduce the purchasing cost,increasing the costeffectiveness of the financial funds,and lowering the risks and hidden troubles in procurements.
ABSTRACT
Objective Objective To find out the existed problems and suggest for possible countermeasures for the patents management through keep track of the trend of patents in Beijing Obstetrics and Gynecology Hospital,Capital Medical University.Methods The data of patents from the department of science and technology in Beijing Obstetrics and Gynecology Hospital,Capital Medical University during 2002-2017 were extracted,to analyze the number of application and grants of patents,type,the authorized inventors'department,project and funding.The method of the stage of technological development was used to deduce the development stage of the technology innovation ability.Results The number of patents application and grants was small in Beijing Obstetrics and Gynecology Hospital from 2002 to 2017.The wave-like increasing trend was observed in the number of patent application,while the stable change in the number of grants of patents.The Compound Annual Growth Rate of the number of application and grants of patents were 14.9％ and 8.2％,respectively.In terms of patent types,most patents (69.2 ％) were utility models patents.The proportion of service invention was 50％.The grants of patents were not affected by research funding.The technology innovation ability of patent is developing,and there will be a rising trend in the future.Conclusions The hospital should strengthen the patent management,improve the management of patent policy,cultivate full-time professional staff,strengthen the cooperation with the patent agency and enterprise,and the construction of patent conversion platform to promote development of patent quality.
ABSTRACT
A wide-band patch probe excited by coaxial line, which is useful for noninvasive measurement of superficial tissues at high frequencies, is presented in this paper. Optimization of the probe is performed by genetic algorithm (GA) combined with Finite Difference Time Domain (FDTD). Then the optimized round patch probe is used to measure reflection coefficient for 1-7 GHz. The measured results show some interesting phenomena, which are very useful for reconstruction of electric properties of superficial tissues.
