Background: Bangladesh’s tea industry is essential to the country’s economic expansion. Since tea workers in Bangladesh are marginalized within our community, they have limited access to comprehensive eye care services. Productivity and well-being are cornerstones of comprehensive health care strategy. Ocular disorders are influenced by life expectancy, sociodemographic status, and the epidemiological transition. In this context, the state of ocular health and the many eye illnesses remain to be significantly addressed. Purpose: To evaluate the pattern of eye diseases among tea workers in a tea estate of Bangladesh. Methods: This cross-sectional observational study was carried out in Halda Valley Tea Estate, Nazirhat, Fatickchari, Chattogram, Bangladesh, under the supervision of the Department of Community Ophthalmology, BSMMU, following ethical clearance and approval by the IRB board of BSMMU. With informed written consent and approval from the authority of the tea estate, a total of 110 tea workers were recruited. Socio-demographic characteristics, ocular findings, and patterns of eye diseases were determined and recorded. Results: The mean age of the study participants was 39.60 ± 11.63 years. The maximum (58.1%) study participants were 31 - 50 years old, female (64.5%), illiterate (82.7%), and tribal (71.8%) indigenes. Eye diseases were found in 94.5% of workers. Presbyopia (28.2%), cataracts (27.3%), and refractive error (26.4%) were the most common. Tea workers with eye diseases were significantly older than those who did not have any eye diseases (40.20 ± 11.57 vs. 29.17 ± 7.31 years, p Conclusion: A significant number of tea workers had eye diseases, of which presbyopia, cataracts, and refractive error were the most common.

Agricultural Sciences 2024年第7期15卷 780-799页

作者： Azizul Hoque md. Maniruzzaman Sikder Abul Khair Bangladesh Agricultural Development Corporation Dhaka Bangladesh Department of Botany Jahangirnagar University Dhaka Bangladesh Hamd.rd University Gazaria Bangladesh

An experiment was meticulously conducted at the research field of Bangabandhu Sheikh Mujibur rahman Agricultural University (BSMRAU), Gazipur, Bangladesh, during the 2011-2012 potato growing season to develop integrated crop management practices for the potato seed production of industrial processing varieties Asterix and Courage. Significantly, higher growth and yield parameters were found in the BADC-recommended practice. Later, another experiment was conducted to validate the BADC practice during the 2013-2014 potato growing season in two locations in Bangladesh. Results showed that the production of tuber per hill, tuber weight per hill as well as gross tuber yield per plot, higher proportion of storable seed tubers, and more quality seed potatoes (A-grade and B-grade) seed tubers were found significantly higher in the “BADC developed practice” compared to other treatments. Viral diseases (PLRV and PVY) prevalence was lower in “BADC developed practice”. Moreover, “BADC developed practice” contributed more economic yield by minimizing input cost compared to “Munshiganj advanced farmers’ practice”. Therefore, the “BADC developed practice” was found “superior” regarding yield, quality, and profitability in seed potato production of industrial varieties—Asterix and Courage in Bangladesh.

供热通风与空气调节（Heating,Ventilation and Air Conditioning,HVAC）系统是大型建筑的重要组成部分之一,在商业超市、高层写字楼、室内体育场馆等建筑中广泛使用。HVAC系统的能耗优化控制是建筑设计中的重要问题,也是使用HVAC系统的业主特别关心的问题。实现对HVAC系统能耗的预测是对其进行优化控制的前提,本论文基于受限玻尔兹曼机（Restricted Boltzmann Machine,RBM）和人工神经网络（Artificial Neural Network,ANN）提出了一种预测HVAC系统能耗的新模型。新模型利用了RBM强大的特征提取能力和无监督学习能力,同时利用了ANN的非线性拟合能力。首先,输入训练数据对RBM进行预训练,使得RBM能够自主提取数据的隐含特征信息以供ANN进行学习;然后,将学到的隐含特征信息与原始输入进行有机组合,形成一个协调一致的集合;最后,将整个集合作为输入数据对ANN进行训练,得到预测模型。为了测试新预测模型的准确性,本文利用重庆市某大型商业超市的真实HVAC能耗数据进行数值实验。实验结果表明,新模型的特征提取能力和预测能力都明显高于单独使用RBM或ANN时的结果,与其它HVAC系统能耗预测模型的对比试验结果也表明该预测模型具有较高的准确性。具体指标表现为该模型的平均绝对误差（Mean Absolute Error,MAE）为0.1541%,均方误差（Mean Square Error,MSE）为0.3405%,均方根误差（Root Mean Square Error,RMSE）为0.5835%,均处在一个极低的水平,拟合度值（R）为1,也处于一个较好的水平。数值实验的结果表明本文提出的新模型是准确可靠的,能够用于HVAC系统能耗预测。本文提出的HVAC系统能耗预测模型有望应用于实际的HVAC能耗预测中,为HVAC系统能耗优化控制提供准确的预测保障,同时为HVAC系统能耗预测问题的研究提供新的视角。

An Overview of Soil Improvement through Ground Grouting

Journal of Geoscience and Environment Protection 2024年第1期12卷 51-63页

作者： md.Ratan Bhuiyan Salequr rahman Masum md.Tushar Parvej S M Sanuwar School of Civil Engineering Hydraulic Engineering Tianjin University Tianjin China College of Civil Engineering and Architecture China Three Gorges University Yichang China

Soil is an essential component of what surrounds us in nature, providing as the basis for our infrastructure and construction. However, soil is not always suitable for construction due to a variety of geotechnical issues such as inadequate bearing capacity, excessive settlement, and liquefaction susceptibility. Through improving the engineering qualities of soil, such as strength, permeability, and stability, ground grouting is a specific geotechnical method used. Using a fluid grout mixture injected into the subsurface, holes are filled and weak or loose strata are solidified as the material seeps into the soil matrix. The approach’s adaptability in addressing soil-related issues has made it more well-known in the fields of civil engineering and construction. In the end, this has improved groundwater management, foundation support, and overall geotechnical performance.

1) Background: Osteoarthritis (OA) is defined as a degenerative joint disease that mainly affects the bone. This study aims to evaluate the effect of low-intensity continuous ultrasound (LICUS) treatment on the knee of osteoarthritis patients through home-based intervention using the LICUS medical device. 2) Methods: The clinical trials were designed in a single-arm, open-label, and intervention study. Thirty-five participants, including those who dropped out (12%), were screened and enrolled. The patients received LICUS (1.1 MHz, 1.5 W/cm2, collimated beams) on the knee by the instructions of the investigator at home (5 min/session, 3 times/day, for four-weeks). Outcome measures were assessed using the Visual Analog Scale (VAS) as a primary endpoint and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) as a secondary endpoint to evaluate pain relief and functional recovery of the knee between pre-treatment (baseline) and post-treatment (four-weeks). 3) Results: Knee pain scores measured using the VAS and WOMAC indices were significantly reduced after a four-week treatment with LICUS compared to baseline. Knee stiffness and functional capacity were significantly reduced after the LICUS application. In addition, there were no reports of adverse effects during the study period. 4) Conclusion: Long-term and home-based application of LICUS can be recommended as an alternative option for the treatment of OA patients, as evidenced by the effect of pain relief and knee function recovery.

目的脑胶质瘤及其子区域的全自动分割是计算机辅助肿瘤临床诊断的基础,卷积神经网络在脑部磁共振成像(magnetic resonance imaging, MRI)分割过程中,小卷积核只能提取局部特征而无法有效融合全局特征,缩小了对影像信息的感知范围,从而导致分割精度不足的问题。本研究旨在利用膨胀卷积,针对三维(three-dimensional, 3D)-UNet不能充分提取全局特征的问题进行改进。方法 (1)算法构建:本文提出一种带有三条全局上下文特征提取通路的3D-UNet模型,即3DGE-UNet模型。使用脑部肿瘤分割挑战赛(Brain Tumor Segmentation Challenge, BraTS)2019提供的公开数据集(335例患者),设计一种全局上下文特征提取(more global contextual feature extraction, GE)模块,并将该模块引入到3DUNet网络的第一、二、三条跳跃连接处,利用该模块充分提取图像的不同尺度全局特征,并与上采样得到的特征图叠加,扩大模型感受野,实现不同尺度特征的深层融合,从而完成端到端的脑肿瘤全自动分割。(2)算法验证:图像数据来源于BraTs2019数据集(335例患者术前MRI图像,包括T1、T1ce、T2和FLAIR四种模态图像和一张医生标注的肿瘤标签图像),将数据集分别按照8∶1∶1划分为训练集、验证集和测试集。以医生标注的肿瘤标签图像为金标准,使用Dice系数(综合评价有效性)、敏感度(病灶区域的查全率)和95%Hausdorff距离(肿瘤边界的分割精度)在测试集中评估算法对完整肿瘤区域(whole tumor, WT)、核心肿瘤区域(tumor core, TC)和增强肿瘤区域(enhancing tumor, ET)三种区域的分割性能,分别使用无GE模块的3D-UNet模型和有GE模块的3DGE-UNet模型进行检测,内部验证GE模块设置的有效性。使用3DGEUNet模型、ResUNet、UNet++、nnUNet、UNETR检测上述性能指标,并比较5种算法模型的收敛性,外部验证3DGEUNet模型的有效性。结果 (1)在内部验证中,改进的3DGE-UNet模型在测试集中分割WT、TC和ET区域的Dice均值分别为91.47%、87.14%和83.35%,与传统的3D-UNet模型相比(89.79%、85.13%和80.90%),综合评价达到了最优值,对于三个区域的分割精度都有提升(P<0.05)。3DGE-UNet模型与3D-UNet模型相比,ET区(86.46%vs. 80.77%)具有更高的敏感度(P<0.05),在查全率方面表现更为优越,在面对病灶区域时,3DGE-UNet模型更倾向于正确识别并捕获更全面的阳性区域,更为有效地避免漏诊发生。3DGE-UNet模型在肿瘤WT区域边缘分割的出色性能,其95%Hausdorff距离均值优于3DUNet模型(8.17 mm vs. 13.61 mm,P<0.05),但在TC区(8.73 mm vs. 7.47 mm)和ET区(6.21 mm vs. 5.45 mm)的性能表现与3DUNet模型相似。(2)在外部验证中,其余4种算法仅TC的Dice均值(87.25%)、WT的敏感度均值(94.59%)、TC的敏感度均值(86.98%)和ET的平均95%Hausdorff距离(5.37 mm)优于3DGE-UNet模型,但差异无统计学意义。3DGE-UNet模型可以在训练阶段快速收敛,速度优于其他外部模型。结论 3DGE-UNet模型可以有效地提取和融合不同尺度的特征信息,提高脑肿瘤分割的准确性。
