An automatic method for the analysis of the questionnaires in psychology, bio-medicine and clinical data

This paper describes an automatic method for the treatment of the information gathered by means of a series of questionnaires. This method is based on the transformation of the questionnaires in a binary form, whatever are their contents. The fields of application cover psychology, sociology, medicine and others. There is no limit to the size of the populations to be studied under any characterizing profile. Any subgroup can be selected and studied, depending on one or more anamnestic character. The standard outputs of the programs consist of: 1.—A basic statistical analysis. 2.—An analysis of the questionnaire validity. 3.—A quantitative evaluation of the attitude toward a “cognitive” problem or aptitude to a test. Computer programs are written in FORTRAN IV for an IBM System (batch mode) or HONEYWELL (Time-Sharing). Both versions can be obtained by request to the authors.     

基于政府职能转变与市场发展效果的大型医用设备配置管理策略研究

以当前政府职能转变中的政府与市场关系为视角,分析大型医用设备配置管理策略的发展过程,总结并预测管理趋势。研究发现我国大型设备配置管理发展可分为萌芽期、管理空窗期、成长期和转型期四个阶段;四个阶段的管理模式分别为质量管制为主的综合监管、市场主导、数量管制为主的综合监管、法律监管;萌芽期的监管明确了行业标准、培养了专业人才、管理效率较低;市场主导引发设备数量的迅猛增长、配置效率较低;成长期的数量监管规范了市场及设备合理使用;转型期的法律监管正在形成。现阶段医院缺乏合理配置大型设备的内在动力是导致市场失灵的主要因素;在法律框架下,采用配置许可的政府干预是未来一定时期内大型设备配置主要的管理方式。     

大型医用设备配置与管理工作思考及对策

目的:为优化大型医用设备配置与管理工作提供政策性建议和参考。方法:采用文献评阅及实地调研的方法,简析在政策实施过程中出现的问题,并提出相应的对策。结果:尽管国家在对加强大型医用设备的配置与管理工作进行积极地探索与实践,但在实施过程中仍浮现出许多问题,大型医用设备的管理体系不健全,配置与管理工作并没有达到预期的效果。结论:大型医用设备配置与管理工作应从宏观和微观、政策建议及配套措施3个层面加强管理力度,实施管理政策。     

Childhood hearing impairment in northern Finland,etiology and additional disabilities

ObjectivesThe purpose of this study was to determine the prevalence and etiology of hearing impairment (HI) in Finnish children and to evaluate the frequency and type of additional disabilities among children with HI.MethodsSubjects consisted of 214 children with mild to profound HI ascertained until the age of 10 years. They belonged to the birth cohort spanning the years 1993–2002 in northern Finland. The clinical data were collected from the electronic patient records of the Oulu University Hospital. Age at ascertainment, degree and type of HI and audiogram configuration were determined. Risk factors and etiology of HI and co-existing disabilities were recorded.ResultsThe prevalence of childhood HI was 2.3/1000 live births (95% CI; 2.0, 2.7). The etiology of HI was genetic in 47.2%, acquired in 16.4% and unknown in 36.4% children. Among the 214 children with HI, 101 (47.2%) had other minor or major disabilities. The frequency of additional disabilities did not differ between children with mild HI and those with moderate or severe HI (p = 0.78). Additional disabilities were more common (65.7%) in children with acquired HI than in children with genetic or unknown HI (43.6%) (p = 0.035).ConclusionThe prevalence of childhood HI has remained unchanged in northern Finland as compared to previous studies. Genetic causes were the most common (47%) etiology of childhood HI. Among acquired causes of HI, perinatal risk factors were more common than previously. The frequency of additional disabilities was similar among children with different degrees of HI. Because almost 40% of children had one or more additional disabilities affecting development or learning, it is important to take them into consideration in rehabilitation.     

Full mapping tensile bond strength of luting in search for differences due to centripetal curing shrinkage

Objectivestesting if hypothetical transverse centripetal strains due to polymerization contraction of luting materials produce differential alterations in its bonding to luted structures, depending on distances to the center of the luting mass, and if this effect is C-factor related. Two hypotheses were tested: (1) there is a statistically significant decreasing relationship between the bonding strength and the transverse distances to the center of the luting material, and (2) there is a statistically significant difference between bonding strengths among luting spaces with different configuration factors.Methods10 PMMA (15 mm Ø) pairs of cylinders were cemented (Scotchbond Universal adhesive & Relyx Universal, both chemically cured) in a compliant setup under two (20 and 70 N) luting forces forming 2 groups (5 samples each), resulting in different C-factors. Whole samples were sectioned in x and y directions obtaining non-trimmed beams from all along the luting surfaces. Their relative positions in each sample were assessed before separating and categorized (10 categories) according to their distances to the center of the sample. All beams were tested in tension and, because of their uneven bonding areas and to balance its influence, UTS results were transformed into UTS_res. First hypothesis was tested trough a linear relationship between UTS_res and distances to vertical centers per samples. Second hypothesis was tested using Mann-Whitney U tests to compare UTS_res between groups, along all categories. Further Weibull analysis was applied.ResultsANOVA’s p of the regression UTS_res – categories were statistically significant for all samples in group 70 N and for all except one in group 20 N: first hypothesis is partially maintained. Although Mann-Whitney tests p comparing UTS_res of both groups for all categories but the first were statistically significant this hypothesis was maintained relying in Weibull analysis. Significance: bonded attachment of cemented materials decreases from centers to outbounds in plane, extensive surfaces, and this decrease is C-factor related.

用波速学说分析正常人F－V曲线形状形成的力学机理

５７２例正常男女青少年用ＤＭＦ－８６型肺功能仪，２６２例正常男女成人用ＬＲ－８０型流速容量仪测定其最大呼气流量一容积曲线（ＭＥＦＶ或Ｆ－ｖ曲线），并用波速学说分析其Ｆ－ｖ曲线形状形成的力学机理，认为可将Ｆ－Ｖ曲线形状分为平台型、直线型、凸型和凹型四大类。平台型的特点是：恰在顶峰之后有一快速的首次下降；接着为下降缓慢的平台（ｐｌａｔｅａｕ）；然后为第二次快速下降形成的拐点（ｂｕｍｐ）或膝（ｋｎｅｅ）；最后为缓慢下降的尾部，其中可能出现或多或少的小拐点。其余三型都可视为以平台型为中心的各种变异。本研究提示，前人应用波速学说在模型与动物的研究，可以扩展到对正常人Ｆ－Ｖ曲线形状形成的呼吸力学机理的探讨。
