浅谈脱困发展的人才管理

只要收入有差别，就不排除人才流失的可能。趋利性也决定了企业要稳定人才队伍的难度。人才流失是长钢目前面临的难题，也是电信等其他国有企业面临的共同难题，如何稳定人才队伍，又如何在人才流失的情况下，使企业生产经营受到尽可能小的影响，本文认为应该强化分配体制改革，加大品种结构调整并加大品种生产力度，从创造的效益中提取一部分，设立从技术人员到操作人员的创新能达到的奖项，从而按比例地提高技术人员、干部职工的待遇。

知识型员工作为掌握科学技术知识的稀缺资源,已日益成为各企业争夺的对象。对企业而言,如果知识型员工的流失率超过行业正常的流动水平,则不仅意味着人才的流失和智力资本的贬值,而且还伴随着技术和商业机密的外泄,给企业带来的负面影响将是巨大的,甚至是致命的。正因如此,面对知识型员工流失,企业应未雨绸缪,事先制定针对性的s,以便最大限度的保留企业发展所需的人才。     

Investigation of Factors Affecting Vertical Drain Behavior

Some influencing factors on vertical drain behavior were investigated by laboratory tests as well as by back-analyses of test embankments on vertical drain improved subsoil at Saga Airport, Saga, Japan. Based on the results from this study, suggestions are made on determining the design parameters for vertical drain improvement. For the discharge capacity test of a prefabricated vertical drain, confining the drain in clay is essential. Also, due to the creep of the filter and the clogging caused by the fine particles entering the drainage channel, the long-term discharge capacity is significantly smaller than the short-term one, and this should be considered in design. For smear effect, a new equation is proposed for determining the ratio of the hydraulic conductivity of the natural subsoil to that of the smear zone, which considers the fact that laboratory tests normally underestimate the hydraulic conductivity of natural deposits. Regarding the effect of the sand mat, the numerical analysis results in this study show that if the hydraulic conductivity of sand is larger than 10?4 m∕s, the assumption of a free drainage condition in the sand mat may not result in significant error. Finally, a methodology of predicting the behavior of vertical drain improved subsoil is proposed.     

Functional Relationship to Describe Drains with Entrance Resistance

Numerical flow models usually represent drains as a system dependent boundary condition. If soil is saturated, drains act as the Dirichlet boundary condition with pressure head set equal to zero, and if soil is unsaturated, drains act as the Neumann boundary condition with flow set equal to zero. The underlying assumption is that drains exhibit ideal behavior. In reality, however, this is generally not so, and the flow encounters additional resistances due to pipe slotting and clogging of the envelope material around the drains. To account for the resulting resistance, a Hooghoudt-type boundary condition was developed that prescribes drain flow in relation to the groundwater level at a reference position. The measured drain discharge in an old drainage system was compared with calculated discharge assuming an ideal drain. It was found that the ideal drain assumption led to large errors in simulated discharge. With a correctly formulated and calibrated Hooghoudt boundary condition, however, more accurate drain discharges were obtained.     

Application of Two Drain Spacing Formula for Mexico’s Humid Tropical Zone

The influence of spatial variability of saturated hydraulic conductivity (K) on drain spacing (L) calculations, based on Kostyakov and Hooghoudt steady state equations, was studied in plots with L equal to 10, 20, and 40 m. The drain discharge rate (q) and the midpoint water-table height above the drain were measured. Then, the K values required to obtain the actual drain spacing by means of the equations were found by trial and error. When using the Hooghoudt equation different values of the depth of the “impermeable” layer were also assumed. For the plots with L equal to 10 and 20 m the use of any central tendency estimator of K practically would have produced the actual drain spacing. However, for the plot with L equal to 40 m, none of these estimators would have produced this drain spacing. It is recommended to increase the number of K measurements to at least one per hectare and to use q equal to 0.01 m/d for humid tropical areas with similar climatic, soil and agronomic conditions.

A case of brain abscess accompanied with sudden-onset hemiplegia as initial manifestation

A 58-year-old male experienced a sudden stroke-like onset of right hemiplegia and numbness of his right upper limb while engaged in his desk-work on April 7, 1997. He had a past history of diabetes mellitus and hyperlipidemia. On admission, he had no fever and the blood pressure was 140/70 mmHg. General physical examination was unremarkable. Neurological examination showed 4/5 strength of his right unilateral extremities and numbness of his right upper limb. Clinical features and computed tomography (CT) without contrast medium at the onset of hemiplegia suggested a stroke. Seven days after admission, his consciousness worsened and body temperature fluctuated between 37 and 38 degrees C. Subsequent Gd-enhanced magnetic resonance (MR) which demonstrated an irregular shaped ring-enhancement lesion and lumbar puncture 9 days after admission was compatible with the diagnosis of brain abscess. Surgical drainage confirmed the presence of brain abscess due to alpha-streptococcus. It improved following surgical drainage and antibiotic therapy with PAPM.BP 2 g/day and PIPC 4 g/day. An afebrile patient of sudden stroke-like onset may be a rarity to be added to the differential diagnosis of brain abscess.     

Finite-Element Grid Configurations for Drains

Several different finite-element grid configurations were evaluated for use in the numerical approximation of steady and transient flow to a single drain. By comparing the numerically simulated drain flow rates and head distributions with analytic values, a nested configuration was found to be appropriate for an effective drain radius of 0.01 m, and a square configuration was suitable for an effective drain radius of 0.05 m. Using an analytic solution, a method was developed to determine the distance of influence of a drain as a function of its effective radius and the geometry of its flow domain. The distance of influence was found to be independent of material type. An appropriate between-drain grid spacing was selected for the numerical simulation of multiple drains by increasing the grid mesh spacing outside the distance of influence. The position of the water table and drain flow rate with time were used to evaluate the between-drain grid spacing for transient variably saturated flow. Grid Péclet and Courant numbers, together with the shape of the solute advance front, were used to evaluate the suitability of the selected single drain configuration and between-drain grid spacing for solute transport. The resulting finite-element grid configuration for single and multiple drains ensures a stable efficient numerical solution, and it has applicability to numerical modeling of multiple subsurface drains.
