医学工程人员培训及工作满意度现状分析

目的 对医学工程人员的基本情况、培训情况、培训需要以及工作满意度情况调查,为医学工程人员的继续教育和管理提供建议。方法 取武汉三级医院8家、二级医院2家,在每家医院的医学工程部门中随机抽取15名进行问卷调查。结果 调查医学工程人员138名,大专及以下学历占47.9%;97.8%的医学工程人员愿意接受在职教育和培训的意愿;对职称、收入、在医院的地位、晋升机会满意的比例为17.4%、13.1%、15.2%、19.6%。讨论 医学工程人员整体学历偏低;医学工程人员培训需求较大;医学工程人员对职称、收入、在医院的地位、晋升机会、在职教育和培训的机会等满意度均较低。医院应建立科学的职业晋升制度、激励制度、培训方案,同时鼓励医学工程人员积极参加培训。

森林经营决策支持系统的设计与实现及在采伐中的应用

我国传统的森林经营方式比较落后,数字化水平不高,决策过程比较盲目.在地理信息系统平台中集成森林动态模型,建立森林经营决策支持系统,可以充分发挥地理信息系统的可视化、空间分析以及模型模拟预测功能,加强处理森林在较大时空尺度上的动态变化的能力.本文设计并实现了森林生长率模型、景观采伐模型和矩阵模型,开发了森林经营决策支持系统,回答森林采伐经营中“采多少,采哪里,怎么采”的三个主要问题,在长白山区的露水河林业局和三岔子林业局进行应用,为提高我国森林可持续经营管理的数字化水平提供了技术支持.

The relationship between the Met allele of the BDNF Val66Met polymorphism and impairments in decision making under ambiguity in patients with obsessive-compulsive disorder

Brain-derived neurotrophic factor (BDNF) gene has an important link to neurotransmitter systems, including serotonin, and seems to play a major role in emotional decision making. Impairment of decision making is an important feature of psychiatric disorders such as obsessive-compulsive disorder (OCD). We explore the link between decision making and the BDNF Val66Met polymorphism, which results in a reduction of BDNF activity, in a sample of Caucasian OCD patients. We used the Iowa Gambling Task (IGT) to measure decision making in 122 OCD patients. All patients were assessed using the Yale-Brown Obsessive-Compulsive Scale, the Beck Depression Inventory, the Beck Anxiety Inventory and the Raven Progressive Matrices. Patients also performed the Continuous Performance Task (CPT-II) and the Trail Making Test (TMT). We grouped Met-allele carriers because these act in a dominant way. Met-allele carries exhibited low performance on both halves of the IGT (first half -F = -2.51, df = 120, P = 0.01; second half -F = -2.32, df = 120, P = 0.02). However, logistic regression analyses showed that the influence of the Met allele seemed to be restricted to the first half of the IGT [first half -β = 0.55, df = 1, P < 0.01, odds ratio (OR) = 5.62; second half -β = 0.32, df = 1, P = 0.15, OR = 2.30]. No differences were observed in tests used to evaluate executive functions associated with the dorsolateral prefrontal cortices (TMT and CPT-II, df = 120, P > 0.05 for both). Met-allele impairment may only be related to decisions made under ambiguous conditions. The null results involving TMT and CPT-II are possibly related to the dysfunction of the orbitofrontal cortices that is associated with OCD.     

Optimal foraging for multiple nutrients in an unpredictable environment

Foraging theory has typically been concerned with the acquisition of a single resource even though organisms from mammals to protozoa are capable of balancing their requirements for multiple resources. Existing theory concerning multiple nutrients from multiple foods does not predict the sequence of food selection. We constructed an optimisation model of the simplest case of two foods containing differing amounts of two nutrients. We begin with the well-supported assumption that reproductive value declines with the distance from target nutrient intake. We show that nutrient space divides into two distinct areas where the animal should exclusively consume one food or the other. The organism thus initially concentrates on one food type until the border between the areas is reached and then moves as closely as possible along the border to approach the target. This strategy is commonly observed in a range of organisms, suggesting that the assumed fitness function is common.
