Objective:To explore the relationship between marital satisfaction and character strengths in young people. Methods:An online survey was delivered to 307 married people (aged 2 1 -44 with years of mar-riage 0-20). Marital satisfaction was measured with the Evaluating and Nurturing Relationship Issues,Communica-tion,and Happiness (ENRICH,including intrapersonal,interpersonal,and external factors and marital satisfaction). Character strengths were measured with Values in Action Inventory of Strengths (VIA-IS,total 24 character strengths were classified into 4 high level character strength factors including heart-focus on self,heart-focus on oth-ers,mind-focus on self,mind-focus on others). Results:All 24 character strengths scores and 4 high level character strength factors scores were positively correlated with marital satisfaction score (r=0. 17 -0. 53,Ps<0. 01 ). Four high level character strength factors positively affected marital satisfaction through the mediation of 3 marital factors. Conclusion:The results indicate that the young people's marital satisfaction is closely related to their char-acter strengths,and character strengths affect marital satisfaction through 3 marital factors.

Objective:Based on the national standard of Classification and Codes for Fixed Assets(GB/T 14885),it created a catalogue of the fixed assets specific for hospital,which became a tool for the delicacy management of the fixed assets in hospitals.Methods:Based on the compiling principles and application scope,it conducted comparative analysis between the national standard and the catalogue which was created by the First Affiliated Hospital with Nanjing Medical University.Results:The amounts of the categories were significantly less than that of national standard.Among them,the categories of medical equipment and furniture were clearly more than the national standard.Conclusion:The effect of the national standard was limited in the delicacy management of the fixed assets in hospitals.However,the specific catalogue helped to uniform the value management and material management,to support information system of fixed assets in hospitals and enhance the level of delicacy management of the fixed assets in hospitals.

The growing trend of childhood obesity has attracted much attention globally.Overweight and obesity are not only popular in developed countries,but have spread to developing countries.China has entered an overall epidemic stage of childhood obesity.Studies have shown that obesity does not only impairs children's health,but also leads to health hazards in adult stage.Diabetes,coronary heart disease and other cardiovascular diseases may take place sooner or the incidence may become higher.The causes of obesity include genetic,early life events,physical activity patterns,diet and social psychological factors.This article reviews the current epi-demic status and the influencing factors of childhood obesity worldwide.

Objective To investigate the demands and problems of the sharing and construc-tion of teaching resources in medical universities. Method A self-designed questionnaire named The questionnaire of the present situation and demand of teaching resources sharing platforms in medical universities in China was used to conducted in all the attainders during a national teaching resources meeting, and SPSS 17.0 was used to analyze the data. Results Among 125 valid questionnaires, 117 people (93.6%) think it's necessary to establish the resources sharing platform, what's more 108 people (86.4%) believe that education resources sharing platform is very helpful for teaching, and multimedia materials, online courses, course wares, teaching cases, website of subject resources and other educa-tion resources should be widely shared. Our investigation has involved 48 medical universities from all over the country, in which 33 medical universities have teaching resources sharing platform. However, 20 (60.6%) of the universities have still not updated the content on time. There are 10 main factors which influence the using of the education resource sharing platform, in which 105 (84%) of them have con-sidered the factor as backward concepts, 91 (72.8%) think that there exist problems in resource con-struction mechanism, 76 (60.8%) think to be the standardized and universal problems. Conclusion It is necessary to build the education resource sharing platform. In all, we should change the traditional education concept and consciousness, strengthen mechanism of management, and exploit high quality education resource to improve the sharing level of education resource in medical universities.

Objective:To analyze and evaluate population health informatization development of China. Meth-ods:Through this investigation, 8 578 copies of a questionnaire designed for all levels of health administration and parts of primary hospitals were collected. These collected data, were analyzed to evaluate the population health infor-matization development of China through the evaluation index system established for population health informatization development and comprehensive evaluation model. Results:The results of this empirical study indicate that the popu-lation &Health Informatization overall has rapid development , but still has regional differences, and total score of the top 10 provinces are Zhejiang, Shanghai, Jiangsu, Liaoning, Beijing, Chongqing, Tianjin, Hunan, Henan and Gan-su. A statistical difference (p<0. 05) exists in regional development on population & health informatization of Chi-na, therefore serval provinces have obvious weakness or advantage in the construction of informatization. Discussion& suggestions:Government of China should pay attention to evaluation during the construction of informatization;pro-mote a balanced and sustainable development by strengthening financial support and optimizing the input pattern;up-grade regional population health informatization overall according to the information resources as the core;and develop the key priorities of population health informatization depending on practical situation and developing trend.

The quality control methods are the important to improve the exactness of diagnses and the effectivity of treatment.X-ray imaging quality is an important factor in improving the X-ray diagnosis effect.To serve this purpose,medical engineering personnel should do the X-ray quality control regularly to keep every parameter in accordance with national standards and demands.The quality control methods for several important indexes of X-ray generators are also discussed.[Chinese Medical Equipment Journal,2008,29(2):99-101]

The paper puts forward the design and application of an imaging analysis system for micro-particles.The structure of the system,design theory and its application are discussed in the paper.

The quality of technicians is the dominate factor to determine the level of medical engineering section.The key to improving technical skills is to do basic jobs.During the Tenth Five-Year-Plan,we not only did many basic jobs and research works in science but did a lot of revolutions in order to accelerate the development of medical engineering and improve the working quality.Compared with the past,we have made great progress and development in standardized management,technology support,technician education,scientific researches,studies,technology level,the quality of service,etc.

This paper introduces the method of electron tomography three-dimensional reconstruction,which is widely applied in structural biology field and summarizes its advantages and disadvantages.The aim is to provide a reference for the application of the method.
