Development trend of urban design in “digital age”: Pan-dimensionality and individual-ubiquity

《结构与土木工程前沿（英文）》 2021年 第15卷 第3期   页码 569-575 doi: 10.1007/s11709-021-0735-7

摘要： The wave of “digital age” featuring digital information is coming. Digital technology is profoundly changing the societal development direction and evolution paths. It also has significant bearing on production modes, social interactions and lifestyles. With regard to urban design, a system of knowledge about the creation and adaptation of material space forms that integrate humanities, art, technology and materials, digital technology has provided it with a brand-new and revolutionary scientific impetus for its evolution. The result of this evolution is “digital urban design paradigm based on human-computer interaction”, i.e., the urban development is moving toward “pan-dimensionality” and “individual ubiquity”. The future of urban design will construct a new approach to urban research and engineering, which is more complex, capable of accommodating and compatible with multiple goals of “instrumental rationality” and “value rationality”. Such a new approach shall be led by the probabilistic theory of “gray scale thinking”, reflecting quaternary synergetic view of “scientific rationality, ecological rationality, cultural rationality and technical rationality” to realize the cognitive progress of “engineering for the benefit of mankind”.

Leveraging individual-level data to advance air pollution health risk management

Jianxun YANG, Wenjing WU, Miaomiao LIU, Jun BI

《工程管理前沿（英文）》 2022年 第9卷 第2期   页码 337-342 doi: 10.1007/s42524-022-0189-1

摘要：

Environmental health risk management is a systematic engineering task, engaging multiple disciplines from the academic and government sectors. Reducing environmental health risks has become one of the key targets in the United Nations Sustainable Development Goals (SDGs). This target has been translated into public policies at many jurisdictional levels (Yue et al., 2020). To design region-specific and targeted policy initiatives, understanding how environmental health risks are spatially distributed and temporally resolved is fundamental.

Along with the advances in high-resolution pollution mapping and projection, environmental risk assessment and management have been performed at a highly granular scale (Caplin et al., 2019). For instance, taking advantage of the fine air pollution dataset, recent research efforts have evaluated the health burdens of historical air pollution exposure or cost-benefits of pollution control policies at finer-scale administrative units and grids (Liu et al., 2017; Ou et al., 2020). These assessments reveal expensive health costs of air pollution exposure and highlight that the health outcomes of air pollution are unevenly distributed across regions and more evident among vulnerable populations (Colmer et al., 2020).

Even though detailed geospatial mappings of air pollution capture local patterns, they do not necessarily represent individual-level unique exposure experiences and health outcomes. Personal exposure to air pollution can be influenced by a range of behavioral factors such as mobility patterns and self-protective actions (Tainio et al., 2021). Individual cofactors such as risk perceptions of air pollutants, baseline health conditions, and socio–economic status also influence the pollution-related health impacts (Piel et al., 2020). Dramatic variations in health risks, therefore, occur even within small spatial units such as blocks and neighborhoods. Thus, individual-level exposure and health assessment are critical in advancing the engineering management of air pollution at granular spatiotemporal scales and informing targeted local policies for reducing pollution-related health risks.

To perform air pollution health risk assessment and management at the individual level, first, gathering datasets relevant to personal exposure experiences and health outcomes is important. For example, portable sensor technology is widely applied, in which participants carry the sensors to measure their real-time locations and micro-environmental exposure (Su et al., 2017). These monitors can illustrate individual time–activity patterns and assess personal-specific pollution exposure during outdoor activities such as daily commuting and exercises (Dons et al., 2017). These activities finally form direct flows of datasets on human behaviors and are made available to researchers for more nuanced characterizations of environmental risk.

In this comment, we summarize different types of individual-level data and outline pathways through which the data may advance air pollution health risks assessment. We then review representative studies revolving around these aspects and showcase how abundant information at the individual level improves environmental health risk management. We finally detail the challenges and uncertainties in this rapidly growing field and highlight the priorities in future research. The aim is to motivate local policy actions and foster collective research efforts to promote public health.

Public perception of environmental issues across socioeconomic characteristics: A survey study in Wujin

Jun BI, Yongliang ZHANG, Bing ZHANG,

《环境科学与工程前沿（英文）》 2010年 第4卷 第3期   页码 361-372 doi: 10.1007/s11783-010-0017-4

摘要： In developing countries, there is controversy over the correct perception regarding environmental and developmental issues. Few studies have examined the perception of low-income nationals in regards to social and environmental issues. This paper looks at the relationship between socio-demographic factors and the groups’ perceived priority regarding environmental and social issues in Wujin County. The results indicated that most residents, specifically the young, government employed and the urban community consider environmental issues to be serious, especially in relation to air pollution and water pollution. Furthermore, many residents feel it is important to rank environmental problems that are related to other social and economic issues, and that environmental protection must be set as a priority in Wujin County. Compared to social issues, environmental concern was greater among the young, government employed, and the urban community, because of their higher education and affluence. In addition, 66.2% of residents consider environmental protection to be more important than economic development. Thus, environmental protection must be set as a high priority in Wujin County, in order to face the many social and environmental challenges inherent in development.

Perception of people for the risk of Tianwan nuclear power plant

Lei HUANG, Jun BI, Bing ZHANG, Fengying LI, Changsheng QU,

《环境科学与工程前沿（英文）》 2010年 第4卷 第1期   页码 73-81 doi: 10.1007/s11783-009-0151-z

摘要： A questionnaire survey of residents’ risk perceptions related to Taiwan nuclear power plant in China was carried out to explore the determining factors that affect individual risk perception. This study proposed to pursue a more comprehensive understanding of factors that affected individual risk perception to nuclear power plants. Covariance structure analysis was conducted using risk perceptions of nuclear power as dependent variable and including interest and knowledge levels of nuclear power, acceptability, benefit perception, trust in nuclear power operation, and trust in government as independent variables. The use of the hypothesis of Elaboration likelihood model (ELM) was also proposed. The results showed that persons with higher levels of interest and knowledge of nuclear power had their own perceptions of risk closely associated with acceptability and potential benefits of nuclear power. In contrast, persons with no interest in and knowledge of nuclear power would have risk perceptions related to their trust in nuclear operation and the government, which partially supported the ELM hypothesis. All these results indicated that the government in China plays an important role in rational risk perceptions, and well-designed communication of risks will help the public to be involved in risk management and improve people’s rational acceptance of risk.

Jian-ru XUE,Di WANG,Shao-yi DU,Di-xiao CUI,Yong HUANG,Nan-ning ZHENG

《信息与电子工程前沿（英文）》 2017年 第18卷 第1期   页码 122-138 doi: 10.1631/FITEE.1601873

摘要： 人类驾驶与自主驾驶在对交通环境的理解方式上有着明显差别。首先，人主要通过视觉来理解交通场景，而机器感知需要融合多种异构的传感信息才能保证行车安全。其次，一个熟练的驾驶员可以轻松适应各种动态交通环境，但现有的机器感知系统却会经常输出有噪声的感知结果，而自主驾驶要求感知结果近乎100%准确。本文提出了一种用于无人车交通环境感知的视觉主导的多传感器融合计算框架，通过几何和语义约束融合来自相机、激光雷达（LIDAR）及地理信息系统（GIS）的信息，为无人车提供高精度的自主定位和准确鲁棒的障碍物感知，并进一步讨论了已成功集成到上述框架内的鲁棒的视觉算法，主要包括从训练数据收集、传感器数据处理、低级特征提取到障碍物识别和环境地图创建等多个层次的视觉算法。所提出的框架里已用于自主研发的无人车，并在各种真实城区环境中进行了长达八年的实地测试，实验结果验证了视觉主导的多传感融合感知框架的鲁棒性和高效性。

《工程（英文）》 2022年 第15卷 第8期   页码 126-132 doi: 10.1016/j.eng.2020.12.024

摘要：

作为一种局部排气通风（LEV）系统，个体患者通风（VIP）隔离罩用于将患者的空气排放物与医护人员（HCW）呼吸的空气进行分离，为减少医院获得性感染（HAI）提供了一种新的途径。最近的研究结果表明，对于典型的患者排放的气溶胶，VIP 隔离罩提供的保护与N95 口罩相当。与口罩不同的是，隔离罩的性能可以被很容易地监控，HCW可以通过警报收到故障提醒。适当使用这些相对简单的设备既可以减少感染控制对个人防护设备（PPE）的依赖，又可以为医院和诊所提供低成本、高能效的防护形式。尽管新冠病毒肺炎（COVID-19）加速了VIP 隔离罩的开发和部署，但这些设备目前仍是一项不成熟的技术。本文描述了VIP隔离罩的现状，并确定了需要进一步开发的方面，包括设备设计和相关使用规则。VIP隔离罩的概念可扩展为为个体患者提供清洁的条件和对其他环境因素如温度和湿度进行个性化控制。

针对水下作业的新型机器人视觉感知框架 Research Article

鲁岳1,陈星宇2,吴正兴1,喻俊志1,3,文力4

《信息与电子工程前沿（英文）》 2022年 第23卷 第11期   页码 1602-1619 doi: 10.1631/FITEE.2100366

摘要：

水下机器人操作通常需要视觉感知（如目标检测和跟踪），但水下场景视觉质量较差，且代表一种特殊分布，会影响视觉感知的准确性。同时，检测的连续性和稳定性对机器人感知也很重要，但常用的基于静态精度的评估（即平均精度（average precision））不足以反映检测器的时序性能。针对这两个问题，本文提出一种新型机器人视觉感知框架。首先，研究不同质量的数据分布与视觉恢复在检测性能上的关系。结果表明虽然分布质量对分布内检测精度几乎没有影响，但是视觉恢复可以通过缓解分布漂移，从而有益于真实海洋场景的检测。此外，提出基于目标轨迹的检测连续性和稳定性的非参考评估方法，以及一种在线轨迹优化（online tracklet refinement，OTR）来提高检测器的时间性能。最后，结合视觉恢复，建立精确稳定的水下机器人视觉感知框架。为了将视频目标检测（video object detection，VID）方法扩展到单目标跟踪任务，提出小交并比抑制（small-overlap suppression，SOS）方法，实现目标检测和目标跟踪之间的灵活切换。基于ImageNet VID数据集和真实环境下的机器人任务进行了大量实验，实验结果验证了所作分析的正确性及所提方法的优越性。代码公开在https://github.com/yrqs/VisPerception。
