Accessory child safety harnesses: Do the risks outweigh the benefits?

Accessory child safety harnesses are available in some countries as alternative restraints for young children or as an accessory restraint used with booster seats. Their use, in Australia at least, is becoming more common. There have been concerns that the risk of misuse of these restraints outweighs any potential benefit this system might have over a retractable lap-shoulder belt system used with a booster seat. However to date there is no evidence to confirm or deny this. This study used laboratory simulated frontal crash tests to examine the performance of accessory child safety harness systems compared to the lap-shoulder belt when used alone and when used with two common designs of Australian booster seat. The performance of the child safety harness system when misused was also investigated. The results demonstrate that the correctly used child safety harness system performed no better than the lap-shoulder system, and in fact allows for a greater risk of submarining. Furthermore, one common form of child safety harness misuse, where the harness is over-tightened causing the lap belt to be positioned high over the abdomen, allowed extremely undesirable dummy motion. This involved gross submarining and direct contact between the harness system and the dummy's neck. These findings suggest that the risks associated with accessory child safety harness systems most likely outweigh any potential benefits, in frontal impacts at least.     

桂林市环城水系水环境整治和通航工设计

桂林市抓住了山水名城的特征，从“水”字上做文章，对环城水系进行整治，兴建两江四湖工程，使漓江、桃花江的游船经船闸或升船机驶入中心城市的木龙湖、桂湖、榕湖和杉湖，更添山水城市独特景观。本文据作者1999－2001年在桂林参与该工程规划设计及工程实施，概要地阐述了两江四湖整治和通航设计中的主要问题，以有对环境景观的要求。这是水利工程服务城市环境的一项环境水利工程，也是新世纪水利工程的一项新课题。

Systematic usability evaluation on two harnesses for a wearable chairless exoskeleton

Harnesses are used in wearable robots in safety, sports, medical, and industrial environments. Wearable robot harnesses for lower extremities should be designed to prevent musculoskeletal disorders caused by excessive strain on the spine and lower extremities when users wear these robots for prolonged periods. Therefore, this study compares and analyzes the usability of the two harnesses—the former (old design) and the latter (new design)—for the Hyundai chairless exoskeleton (CEX). In total, 27 participants took part in this study. The wearability, stability, and overall wearing satisfaction of the former and the latter harnesses were compared. We conducted an experiment where the participants wore the former and the latter harnesses while completing a series of tasks that resembled the ones performed by the workers on a front-end module assembling line of an automobile factory. After the experiment, the participants took part in a survey and semi-structured interviews. The data was analyses by t-test, correlation, and regression analyses. The survey results demonstrated that for the latter harness the cushioning sensation (thigh r = 0.539; calf r = 0.516) had the strongest effect on the overall wearing satisfaction. In addition, the latter harness scored higher in overall wear satisfaction than the previous harness. This study was able to verify the difference between the new and old designs according to the usability evaluation of the harness. The results of this study are considered to be helpful in design to improve the usability of the harness in the future.
