Exploration of Strategies for Chronic Disease Prevention and Control and Relevant System Development

Long-de Wang

《工程管理前沿（英文）》 2015年 第2卷 第1期   页码 2-12 doi: 10.15302/J-FEM-2015002

摘要： Chronic non-communicable diseases have become a major threat to humanity. International studies have shown that of 57 million deaths worldwide in 2008, 36 million (63%) were caused by chronic non-communicable diseases; of these, 29 million (80%) occurred in low and middle income countries. The WHO predicts that if the current trend continues, the annual number of deaths due to chronic non-communicable diseases will increase to 55 million by 2030. Due to acceleration of industrialization and urbanization, along with population aging and rapid changes of people’s lifestyle, the morbidity and mortality from chronic diseases are rapidly increasing in China. Therefore, dealing with the prevalence of chronic non-communicable diseases has become one of the current major health issues for China to address. On the basis of summarizing the status of major chronic diseases in China, analyzing the key issues and key factors in chronic disease prevention and control, and reviewing and summarizing the experience from the previous projects, this paper proposes the following recommendations as strategies for chronic disease prevention and control and development of relevant system, which China should adopt. All relevant government departments should formulate corresponding policies; establish a coordinated and efficient work system with rational structure and clear division of tasks and responsibilities within the system. Implementation and development of “integrated medicine” in system is necessary. Work norms and requirements will then improve the performance and efficiency in chronic disease prevention and control in China.

王陇德

《中国工程科学》 2014年 第16卷 第10期   页码 22-30

摘要：

慢性非传染性疾病已成为当前人类的重大威胁。国际研究表明，2008 年全球5 700 万人死亡，其中的63 %（3 600 万人）死于慢性非传染性疾病；80 %的非传染性疾病所致死亡（2 900 万人）发生在低收入和中等收入国家。WHO预测，如果按目前的情况继续发展，到2030 年每年死于慢性非传染性疾病的人数将增加至5 500 万人。在中国，伴随着工业化、城镇化、老龄化进程的加快和国民生活方式的快速变迁，居民慢性病患病率、死亡率呈持续快速增长趋势。因此，慢性非传染性疾病流行的应对，是中国当前必须尽快考虑的重大问题。本文在总结中国重大慢性病流行状况、分析中国慢性病防控中存在的主要问题和关键影响因素以及总结前期项目探索经验的基础上，对中国慢性病防控应制定和采取的策略及防控体系建设工作要点提出了建议：如相关政府部门都应制定相应政策；建立结构合理、系统内任务分工明确，协调、高效的工作体系；从制度、工作规范与要求上推行“整合医学”的发展，从而提高中国慢性病防控工作效能与效益等。

A novel strategy for the construction of silk fibroin–SiO composite aerogel with enhanced mechanical

《化学科学与工程前沿（英文）》 2023年 第17卷 第3期   页码 288-297 doi: 10.1007/s11705-022-2222-7

摘要： The practical application of silica aerogels is an enormous challenge due to the difficulties in improving both mechanical property and thermal insulation performance. In this work, silk fibroin was used as scaffold to improve the mechanical property and thermal insulation performance of silica aerogels. The ungelled SiO2 precursor solution was impregnated into silk fibroin to prepare silk fibroin–SiO2 composite aerogels via sol−gel method followed by freeze-drying. By virtue of the interfacial hydrogen-bonding interactions and chemical reactions between silk fibroin and silica nanoparticles, SiO2 was well-dispersed in the silk fibroin aerogel and composite aerogels exhibited enhanced mechanical property. By increasing the loading of silk fibroin from 15 wt % to 21 wt %, the maximum compressive stress was enhanced from 0.266 to 0.508 MPa when the strain reached 50%. The thermal insulation performance of the composite aerogels was improved compared with pure silica aerogel, as evidenced that the thermal conductivity was decreased from 0.0668 to 0.0341 W∙m‒1∙K‒1. Moreover, the composite aerogels exhibited better hydrophobicity and fire retardancy compared to pure silica aerogel. Our work provides a novel approach to preparing silk fibroin–SiO2 composite aerogels with enhanced mechanical property and thermal insulation performance, which has potential application as thermal insulation material.

Socialized care services for the aged population: System construction and support measures

《工程管理前沿（英文）》 2023年 第10卷 第2期   页码 339-353 doi: 10.1007/s42524-022-0208-2

摘要： Given the aging society, an increase in social demand, information- and communication technology-driven culture, and government policy support emerges to enable the development of the socialized care services system for the aged (SCSSA). The development of the SCSSA would be a significant step toward addressing China’s aging population. However, the construction of the SCSSA challenges the theories and methods of traditional elderly care service system construction. Specifically, the implementation path for such elderly care service policies is unclear, the necessary technological support is insufficient, and the mechanism for integrating intelligent information technology remains underexplored. Thus, this paper focuses on the needs of the elderly, grounded in the context of the changing elderly care service policies in China, and proposes a research paradigm that integrates system construction and support measure embedding. We then construct the original SCSSA, which includes “material + spirit + medical treatment + healthcare” and propose a method of optimization and iteration. Finally, we build the research framework of systematic support measures from the perspectives of policy reconstruction, institutional embeddedness, and technical support. Our work provides theoretical support and practical guidance for the construction and dynamic optimization of the SCSSA, thus making a significant contribution that will help China effectively cope with its aging society.

《工程管理前沿（英文）》 2016年 第3卷 第3期   页码 275-282 doi: 10.15302/J-FEM-2016035

摘要： The construction industry has long been plagued with a high number of fatalities in the USA. Much safety improvements have been made after the USA Congress passed the Occupational Safety and Health Act in 1970. However, this industry still suffers from a disproportionately high rate of work-related fatalities in comparison to other industries. To provide a holistic view of current construction safety practices and corresponding performance, this paper reviews statistics of construction fatalities and their causes. It then presents efforts led to prevent work-related accidents and injuries by the federal safety agencies and the industry. Additionally, advantages and limitations of current practices in terms of construction safety have been discussed along with promotion of aspects in construction work environment.

Investigating the challenges related to combining BIM and Last Planner System on construction sites

Conrad BOTON, Yaya PITTI, Daniel FORGUES, Ivanka IORDANOVA

《工程管理前沿（英文）》 2021年 第8卷 第2期   页码 172-182 doi: 10.1007/s42524-019-0086-4

摘要： The construction industry is facing a gradual but important transformation toward more productivity and collaboration. In this framework, two major approaches are often cited in the literature as having the potential to improve the practices in the industry: Building Information Modeling (BIM) and Lean Construction. Several scientific studies have demonstrated the synergy of these two approaches and very recent research has reported positive results from the use of software applications as support for their implementation on construction sites. However, the stakes of such integration have been very little studied. This article presents the results of a research project conducted within a general contractor firm that decided to implement BIM and Last Planner System (LPS) on its construction sites. The research uses a four-stage action research approach, including the characterization of the research issue, the establishment of an action plan, its implementation and its evaluation. Compared to recent related studies, the research is less enthusiastic. While it highlights the need for new tools to improve production planning and control, it also points to a strong resistance to change by practitioners at the site. They emphasize the necessity for adequate pre-service training and the need for new resources that can work full-time on the ongoing training of site teams. In addition, some limitations of the tool lead workers to believe that it can quickly become a factor that slows down their daily work rather than improving it. Based on the advice of professionals, the paper formulates some recommendations to the industry, the researchers and the software developers.

Web-based construction equipment fleet management system: cost-effective global and local allocation

Hakob AVETISYAN, Miroslaw SKIBNIEWSKI

《工程管理前沿（英文）》 2017年 第4卷 第1期   页码 76-83 doi: 10.15302/J-FEM-2017012

摘要： Over the last two decades, construction contractors have been gradually making more investments in construction equipment to meet their needs associated with increasing volumes of construction projects. At present, from an operational perspective, almost all contractors pay more attention to maintaining their equipment fleets in well-sustained workable conditions and having a high accessibility of the necessary equipment pieces. However, such an approach alone is not enough to maintain an efficient and sustainable business. In particular, for large-scale construction companies that operate in multiple sites in the U.S. or overseas, the problem extends to an optimal allocation of available equipment. Given the current state of the construction industry in the U.S., this problem can be solved by geographically locating equipment pieces and then wisely re-allocating them among projects. Identifying equipment pieces geographically is a relatively easy task. The difficulty arises when informed decision-making is required for equipment allocation among job sites. The actual allocation of equipment should be both economically feasible and technologically preferable. To help in informed decision-making, an optimization model is developed as a mixed integer program. This model is formed based on a previously successfully developed decision-support model for construction equipment selection. The proposed model incorporates logical strategies of supply chain management to optimally select construction equipment for any construction site while taking into account the costs, availability, and transportation-related issues as constraints. The model benefits those responsible for informed decision-making for construction equipment selection and allocation. It also benefits the owners of construction companies, owing to its cost-minimization objective.

《能源前沿（英文）》 2020年 第14卷 第1期   页码 139-151 doi: 10.1007/s11708-017-0484-4

摘要： In this paper, the genetic algorithm (GA) is applied to optimize a grid connected solar photovoltaic (PV)-wind-battery hybrid system using a novel energy filter algorithm. The main objective of this paper is to minimize the total cost of the hybrid system, while maintaining its reliability. Along with the reliability constraint, some of the important parameters, such as full utilization of complementary nature of PV and wind systems, fluctuations of power injected into the grid and the battery’s state of charge (SOC), have also been considered for the effective sizing of the hybrid system. A novel energy filter algorithm for smoothing the power injected into the grid has been proposed. To validate the proposed method, a detailed case study has been conducted. The results of the case study for different cases, with and without employing the energy filter algorithm, have been presented to demonstrate the effectiveness of the proposed sizing strategy.
