Objectives: Congenital heart diseases (CHDs) are one of the most important congenital anomalies in children which have high-risk for neurodevelopment delay. This study was conducted to determine the proportion of developmental delay in children with CHD and comparison of delay between acyanotic and cyanotic heart diseases in children.

Materials and methods: A cross-sectional study was conducted on children admitted in pediatric ward of rural hospital from 6 month to 6 years of age who are diagnosed with CHD by 2D ECHO and further classified into acyanotic congenital heart disease (ACHD) and cyanotic congenital heart disease (CCHD). Neurodevelopmental assessment was done using Trivandrum development screening chart (TDSC).

Results: Out of total 50 children in study population, 24 children had TDSC delay, distribution as 11 (22%) ACHD and 13 (26%) CCHD. Out of 24 children in the age group of 0-3 years, 13 (54.2%) were ACHD and 11 (45.8%) were CCHD. Out of 26 children in the age group of 3-6 years, 15 (57.7%) were ACHD and 11 (42.3%) were CCHD. Among different ACHD included in the study population (0-3 years) children with ventricular septal defect (VSD) were maximum (n = 5) next in the decreasing order was atrial septal defect (ASD) (n = 3). ACHD included in the study population (3-6 years) children with VSD was maximum (n = 6) next in the order was ASD (n = 4). Proportion of delay in children with ACHD was 22% as compared to 26% in children with CCHD.

Conclusion: There is a high proportion of neurodevelopmental delay in children with CHD which can be detected using TDSC which is a simple screening tool and can be used by any health-care professional without training for the assessment of neurodevelopmental outcome in these children. Delay was more in children with CCHD than ACHD.

目的:先天性心脏病(CHDs)是儿童神经发育迟缓的高危先天性异常之一。本研究旨在确定CHD患儿发育迟缓的比例，并比较无青紫型和青紫型患儿发育迟缓的情况。材料与方法:对农村医院儿科病房6个月~ 6岁经2D ECHO诊断为冠心病的患儿进行横断面研究，并将其分为无青绀型先天性心脏病(ACHD)和青绀型先天性心脏病(CCHD)。采用Trivandrum发育筛查图(TDSC)进行神经发育评估。结果:在50例研究人群中，24例TDSC延迟，分布为ACHD 11例(22%)，CCHD 13例(26%)。24例0 ~ 3岁儿童中，ACHD 13例(54.2%)，CCHD 11例(45.8%)。26例3 ~ 6岁儿童中，ACHD 15例(57.7%)，CCHD 11例(42.3%)。在纳入研究人群(0-3岁)的不同ACHD中，室间隔缺损(VSD)患儿最多(n = 5)，其次是房间隔缺损(ASD) (n = 3)。研究人群(3-6岁)中室间隔缺损患儿最多(n = 6)，其次是ASD (n = 4)。ACHD患儿的延迟比例为22%，而CCHD患儿为26%。结论:TDSC是一种简单的筛查工具，可用于评估CHD患儿的神经发育结局，TDSC可检测出CHD患儿神经发育迟缓的比例较高。CCHD患儿的延迟发生率高于ACHD患儿。

This paper builds a Near-Field Communication (NFC) based localization system that allows ordinary surfaces to locate surrounding objects with high accuracy in the near-field. While there is rich prior work on device-free localization using far-field wireless technologies, the near-field is less explored. Prior work in this space operates at extremely small ranges (a few centimeters), leading to designs that sense close proximity rather than location. We propose TextileSense, a near-field beamforming system that can track everyday objects made of conductive materials (for example, a human hand) even if they are a few tens of centimeters away. We use multiple flexible NFC coil antennas embedded in ordinary and irregularly shaped surfaces we interact with in smart environments---furniture, carpets, and so forth. We design and fabricate specialized textile coils woven into the fabric of the furniture and easily hidden by acrylic paint. We then develop a near-field blind beam-forming algorithm to efficiently detect surrounding objects, and use a data-driven approach to further infer their location. A detailed experimental evaluation of TextileSense shows an average accuracy of 3.5 cm in tracking the location of objects of interest within a few tens of centimeters from the furniture.

本文构建了一种基于近场通信(NFC)的定位系统，使普通表面能够在近场内高精度地定位周围物体。虽然在使用远场无线技术的无设备定位方面已有丰富的前期工作，但近场的探索较少。之前在这个空间的工作范围非常小(几厘米)，导致设计感觉接近而不是位置。我们提出TextileSense，这是一种近场波束形成系统，可以跟踪由导电材料制成的日常物体(例如人手)，即使它们在几十厘米之外。我们将多个灵活的NFC线圈天线嵌入到我们在智能环境中与之互动的普通和不规则形状的表面——家具、地毯等。我们设计和制造专门的纺织线圈，编织到家具的织物中，很容易被丙烯酸漆掩盖。然后，我们开发了一种近场盲波束形成算法来有效地检测周围的物体，并使用数据驱动的方法来进一步推断它们的位置。TextileSense的详细实验评估表明，在距离家具几十厘米的范围内，跟踪感兴趣的物体位置的平均精度为3.5厘米。
