目的调查淄博市儿童青少年的近视现状,并分析年龄、性别以及学校、城乡分布等因素对近视的影响。方法采用横断面研究设计,利用2022年山东省中小学生健康体检数据,共有来自淄博市张店区、高青县和沂源县6~18岁的60899例中小学生接受视力检查和非睫状体麻痹验光。按照目前医疗标准,近视度数小于300度归为低度近视,300~600度归为中度近视,大于600度归为高度近视。研究采用χ^(2)检验分析分类变量之间的差异,采用二元logistic回归方法分析近视的相关影响因素。结果近视、高度近视、视力不良的患病率分别为66.31%、4.63%和41.05%,并且随着年级与年龄的增长而上升,特别是高中阶段,近视率超过了90%,而远视的患病率则呈现相反趋势。多因素logistic回归分析结果表明,高年龄、高年级、女生和城市就读是近视的危险因素。结论淄博市中小学生近视、高度近视和视力不良患病率均处于较高水平,尤其在高中阶段更为严重。近视已成为目前亟待解决的社会问题,需开展有针对性的综合防控措施。

A comparison of IBC with 1997 UBC for modal response spectrum analysis in standard-occupancy buildings

引用

Earthquake Engineering and Engineering Vibration 2011年第1期10卷 99-113页

作者： tariq M. Nahhas Umm Al-Qura University

This paper presents a comparison of the seismic forces generated from a Modal Response Spectrum Analysis （MRSA） by applying the provisions of two building codes, the 1997 Uniform Building Code （UBC） and the 2000-2009 International Building Code （IBC）, to the most common ordinary residential buildings of standard occupancy. Considering IBC as the state of the art benchmark code, the primary concern is the safety of buildings designed using the UBC as compared to those designed using the IBC. A sample of four buildings with different layouts and heights was used for this comparison. Each of these buildings was assumed to be located at four different geographical sample locations arbitrarily selected to represent various earthquake zones on a seismic map of the USA, and was subjected to code-compliant response spectrum analyses for all sample locations and for five different soil types at each location. Response spectrum analysis was performed using the ETABS software package. For all the cases investigated, the UBC was found to be significantly more conservative than the IBC. The UBC design response spectra have higher spectral accelerations, and as a result, the response spectrum analysis provided a much higher base shear and moment in the structural members as compared to the IBC. The conclusion is that ordinary office and residential buildings designed using UBC 1997 are considered to be overdesigned, and therefore they are quite safe even according to the IBC provisions.

Evaluation of line brattice length in an empty heading to improve air flow rate at the face using CFD

引用

International Journal of Mining Science and Technology 2017年第2期27卷 253-259页

作者： Feroze tariq Genc Bekir School of Mining Engineering University of the WitwatersrandJohannesburg 2050South Africa

The effectiveness of line brattice(LB) ventilation system depends on the associated system ***, the effect of these variables on the air flow rates close to the face of the heading is not extensively studied. In this paper, the effect of the LB length in relation to the LB-wall distance on the air flow rate reaching the face is analysed. Scenarios were developed using four LB lengths, two LB-wall distances and two heading depths. These scenarios were simulated with a validated CFD model. The air flow rates and patterns at various locations inside the heading were analysed. This helped to find the minimum LB-face distance that should be maintained for each LB-wall distance to maximise the air flow rate at the face. The minimum length when used will improve ventilation and reduce energy cost.
