建井期间竖井多中段提升施工方案研究

在整个矿山建设工程中,竖井施工结束后,由竖转平施工中段及溜破系统等工程成为制约建井工期的关键因素。由于各个矿山的特点和要求不同,对于无法立即进行井筒永久装备的工程来说,此时利用凿井期间的施工装备来施工中段工程就成了建设及施工单位的共同选择。对于非煤矿山而言,大量无轨设备的使用使得罐笼+有轨矿车运输提升成为了过去式,同时,多中段同时施工也给矿井提升系统带来各种问题,如何保证多中段同时施工的提示系统安全运转,也就成为了一个新的课题。

Health-related quality of life measurement for evaluation research and policy analysis.

Describes a unit of health status, the "Well-Year," which expresses the output of health programs in terms of the number of years and the health-related quality of life produced by a treatment or program. Dividing the cost of the program by the number of Well-Years that it produces gives the cost–utility of the program. This cost–utility ratio can be used in a general health policy model to compare the efficiency of different programs or to assess the relative contribution of different programs and providers in the health-care system. Different components of the model are useful (1) for the effectiveness of medical interventions, (2) to assess the quality of care, (3) to improve clinical decision making, (4) to assess needs of different populations, and (5) to understand causes of variations in health. A comprehensive standardized measure of health status has many advantages for health planning, decision analysis, and program evaluation. An example demonstrates how the relative production of Well-Years by psychologists might be compared to the contribution of other health-care services.

Health-related quality of life in head and neck cancer survivors: Impact of pretreatment depressive symptoms.

Objective: Symptoms of depression are common in those with cancer. The authors investigated whether depressive symptoms assessed before the initiation of cancer treatment predicted diminished health-related quality of life (HRQOL) at follow-up. Design: As part of a large, prospective study of oncologic outcomes, 306 patients with head and neck cancer (HNC) were assessed on several clinical and psychosocial characteristics during a pretreatment clinic visit and then at 3- and 12-month follow-up appointments. Main Outcome Measures: Depressive symptomatology was assessed with the Beck Depression Inventory and HNC-specific HRQOL (main outcome measure) was assessed with the Head and Neck Cancer Inventory. Results: Controlling for age, gender, marital status, cancer site, stage of disease, alcohol and tobacco use, comorbidity status, and pretreatment HRQOL, simultaneous multiple regression analyses revealed that depressive symptoms present at study enrollment, before the initiation of cancer treatment, significantly predicted lower HRQOL at 3- and 12-month follow-up assessments across the 4 HNC-specific domains of speech, eating, aesthetics, and social disruption (all ps ≤ .01). Conclusion: Results suggest that depressive symptomatology present near the time of diagnosis can have a significant, deleterious impact on HRQOL over time in HNC survivors. Thus, it may be useful to assess depression at diagnosis to identify individuals at greater risk for poor HRQOL outcomes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
