An Implementation of a Decision Support Tool to Assess Treatment of Emerging Contaminants in India

Emerging contaminants have been increasingly studied over the past decade to improve the understanding of their fate, occurrence and toxicological effects on the environment and human health. Originally wastewater treatment plants were not designed to remove these pollutants of emerging concern. However, research is now focusing on determining which existing treatment unit processes are suited to their removal. This research sets out to determine suitable treatment options for thirty nine emerging contaminants including various Pharmaceuticals and Personal Care products. The treatment options used in this study are taken from a developed decision support tool (WiSDOM) which formulates wastewater trains/packages for treatment of wastewater in India. The tool also evaluates the performance of each optimal solution in terms of removal of conventional pollutants (such as biochemical oxygen demand, chemical oxygen demand, total nitrogen, total phosphorous, faecal coliform etc.), using multi-objective genetic algorithms and multi-criteria decision analysis. An Excel Spreadsheet Program (ESP) was developed as an add-on to the tool, allowing the ESP to take an initial concentration of any of the thirty nine emerging contaminant and pass it through the treatment trains (generated/selected by the WiSDOM tool) to determine the removal efficiency. Three scenarios were developed to analyse the removal of emerging contaminants in India. The scenarios were designed to capture the influence of different socio-economic contexts and wastewater characteristics on the treatment technology selection. The tool generated results suggest that the use of constructed wetlands can remove a large proportion of emerging contaminants, resulting in low energy requirements and operational costs and wildlife habitats. However, the land requirement for this process is not always suited to urban areas in India. Advanced oxidation processes were also efficient at removing emerging contaminants. However, the energy requirements for this process were high. Emerging contaminants have different physical and chemical properties;therefore, future evaluations of each chemical should be monitored separately to generate suitable technologies suited to optimal removal.

A framework for the use of decision-support tools at various spatial scales for the management of irrigated agriculture in West-Africa

The Kou watershed, situated in the Southwestern part of Burkina Faso, has succumbed since a couple of decades in a typical theater play of anarchistic water management. With its 1800 km2, this small watershed holds the second largest city of Burkina Faso (Bobo-Dioulasso), a former State ran irrigated rice scheme and several informal agricultural zones. Despite the abundance on water resources, most water users find themselves regularly facing to water shortages due to an increase in population and low irrigation efficiencies. Local stakeholders are hence in need of easy-to-use and low-cost decision support tools for the monitoring and exploitation of the water resources at different spatial and user levels. A top-to-bottom string of adapted water management tools has been successfully installed to tackle the problems: from watershed (top) to field level (bottom), passing by the 1200 ha irrigation scheme. Land use maps have been derived from time-series of free satellite images. Combined with data from a network of hydrologic gauging stations, regional water use maps were established. SIMIS was put in place for the public-private management of the regions irrigated rice scheme. Day to day water use on irrigated plots was followed by soil humidity and crop canopy measurements. A simple field-cropwater balance model Aqua Crop was used by extension workers to draft optimal irrigation charts. Each tool was applied independently, requiring only limited data;but their combined results contributed to an improved integrated water management.

Implementation issues of the planning support tool in Japan:Focusing on urban disaster mitigation

This study determined the issues of Planning Support System(PSS)implementation in the field of urban disaster mitigation in Japan by understanding its analytical perspective through a review of Western literature,a questionnaire survey of urban planning consultant companies,and PSS implementation for a practical project in a municipality.Regarding the instrum ental perspective,there was difficulty in conducting the simulationbased PSS due to the enormous simulation time required.Regarding the transfer perspective,the importance of the municipality^decision of adopting the PSS to a project,securing the budget and continuous running costs,track record of the practical project,and lack of human resource for the PSS use were clarified.Regarding the user perspective,the difficulty in data collection and update as well as im portance of the cooperative system/support from the developer in the initial period were clarified.Especially,considering the low number of implementations,a platform may be important for the promotion of PSS awareness.This may be also useful for the diffusion of PSS.It is necessary for the developers to fully comm unicate the benefits of PSS adoption.It is thought that a close cooperative system and support are required in the initial stage.For prom oting and understanding the benefits of PSS adoption,a guideline or manual seems to be useful.This is effective for ensuring the budget and providing an explanation to high-level members of the organizations about the effect of utilizing these tools.For the final implementation,the possibility of installation,maintenance,and operation of the PSS by the municipality was discussed.

Toward the Design and Implementation of Traceability Engineering Tool Support

Requirements of a system keep on changing based on the need of stakeholders or the system developers, making requirement engineering an important aspect in software development. This develops a need for appropriate requirement change management. The importance of requirements traceability is defining relationships between the requirements and artefacts extracted by the stakeholder during the software development life-cycle and gives vital information to encourage software understanding. In this paper, we have concentrated on developing a tool for requirement traceability that can be used to extend the requirement elicitation and identification of system-wide qualities using the notion of quality attribute scenarios to capture the non-functional requirements. It allows us to link the functional and non-functional requirements of the system based on the quality attribute scenarios template proposed by the Carnegie Mellon Software Engineering Institute (SEI). Apart from this, the paper focuses on tracing the functional and non-functional requirements of the system using the concept of requirement traceability matrix.

整体侧墙结构的A型城铁车辆车体挠度预制研究

为探讨具有整体侧墙结构的铝合金A型城铁车辆车体在焊接过程中挠度变化的影响因素,以及挠度的变化规律。采用5组试验车辆,分别调整车体总组成组焊工装支撑分布位置、侧墙单部件的挠度预制,以及车体总组成预制挠度数值,观察车体焊后挠度的变化。结果显示,当支撑分布在门口中心时,焊后挠度回弹量达13 mm;而支撑分布在门口两侧时,回弹量下降至11 mm。在侧墙单部件进行15 mm的挠度预制后,焊后挠度回弹量进一步下降至4.5 mm。此外,当总组成预制挠度数值分别为19 mm、16.5 mm时,焊后挠度值分别为15.3 mm、13 mm,回弹量保持在3.5~4.5 mm范围内。研究表明,车体总组成组焊工装支撑分布位置以及侧墙单部件的挠度预制是影响车体焊后挠度的关键因素。通过侧墙单部件的挠度预制,可有效降低焊后挠度回弹量。此外,在保证设计理论挠度需求的前提下,采用较小的挠度预制对车体尺寸更为有利。

住院患者静脉血栓栓塞症风险感知的研究进展

静脉血栓栓塞症(VTE)是住院患者的潜在并发症之一,包括深静脉血栓形成和肺栓塞,早期预防是降低VTE发病率和病死率的关键。目前VTE预防的指南已较成熟,基于指南的基础预防、机械预防、药物预防的有效性均在临床实践中得到了验证,但主要针对于临床医护人员,患者及照顾者对VTE风险的重视度不足,导致其预防依从性低下。风险感知是人们对风险事物和风险特征的感受、认识和理解,可改善健康相关行为、促进相关预防行为的产生。在预防VTE的过程中,患者因素是重要的一环,患者对VTE的风险感知、依从性与预防效果密切相关。了解患者的VTE风险感知是提高其对VTE预防的主观能动性及依从性的重要途径。本文从患者VTE风险感知的现状、评估工具、影响因素、干预策略方面进行综述。目前患者对VTE风险的认知不足,尚缺乏完整且具有针对性的VTE风险感知测评工具,国内学者主要基于健康信念模式理论和知信行理论对患者的VTE感知进行研究,VTE风险感知受患者个人因素(如年龄、文化程度、社会背景)、患病经历、VTE病史、社会支持、主要照顾者等影响,本文主要从医方、患方、网络媒体等方面探讨应对措施,以期提升患者VTE风险感知水平,提高预防依从性,从而为优化患者VTE预防行为结果、降低VTE发生率的干预研究提供参考。
