The role of the Basic Public Health Service program in the control of hypertension in China: Results from a cross-sectional health service interview survey.

ObjectivesNon-communicable diseases (NCDs) have become the main cause of mortality in China. In 2009, the Chinese government introduced the Basic Public Health Service (BPHS) program to relieve the rising burden of NCDs through public health measures and delivery of essential medical care. The primary aim of this study was to evaluate the impact of the BPHS program on hypertension control.MethodsThe China National Health Development Research Center (CNHDRC) undertook a Cross-sectional Health Service Interview Survey (CHSIS) of 62,097 people from primary healthcare reform pilot areas across 17 provinces from eastern, central, and western parts of China in 2014. The current study is based on responses to the CHSIS survey from 7,867 participants, who had been diagnosed with hypertension. Multi-variable mixed logit regression analysis was used to estimate the association between BPHS management and uncontrolled hypertension. In a follow-up analysis, generalized structural equation modelling (GSEM) was used to test for mediation of the BPHS program effect through patient compliance with medication.FindingsThe estimated proportion of patients with uncontrolled hypertension was 30% lower (23.2% vs 31.5%) in those participants who were adequately managed under the BPHS program. Other predictors of hypertension control included compliance with medication, self-reported wellbeing, income, educational attainment and exercise; smoking was associated with reduced hypertension control. The significant inverse association between uncontrolled hypertension and age indicates poor outcomes for younger patients. Additional testing suggested that nearly 40% of the effect of BPHS management (95% CI: 28.2 to 51.7) could be mediated by improved compliance with medication; there was also an indication that the effect of management was 30% stronger in districts/counties with established digital information management systems (IMS).ConclusionHypertension control improved markedly following active management through the BPHS program. Some of that improvement could be explained by greater compliance with medication among program participants. This study also identified the need to tailor the BPHS program to the needs of younger patients to achieve higher levels of control in this population. Future investigations should explore ways in which existing healthcare management influences the success of the BPHS program.

Potential positive impacts of digitalization of construction-phase information management for project owners

Productivity in the US construction industry has been widely reported to be on the decline and among several causes identified, the lack of innovation in project management practices has been described as having led to lost productivity, especially in the face of growing project complexity and the increasing need for enhanced stakeholder collaboration. Digitalization has the potential to improve project management and thus help in reversing this decline in productivity. However, several public agencies have not fully adopted construction or document management software, known herein as digital construction-phase information management (DCIM) systems. This paper identifies the potential positive impacts that stem from the use of such technologies towards project management with the goal of incentivizing their use. Eighteen such potential positive impacts of DCIM systems on project management for public owners were identified and verified using a systematic literature review and statistical analysis of survey responses from industry professionals. Furthermore, a comparison between two representative types of public owners was performed to identify how owner preferences vary in the industry. The results show an overall agreement amongst end-users regarding the identified potential positive impacts of DCIM systems. The result further identified the top five potential positive impacts with a significant strong agreement. The analysis also identified differences in what impacts were most significant to the two types of tested sub-populations. These findings can enhance project owners’ understanding of the potential positive impacts brought using digitalization in the project administration and delivery process. This research can also enhance DCIM systems developers’ understanding of the needs of end-users, particularly project owners, and guide the development of future solutions for project administration and delivery.

Proof-of-Contribution consensus mechanism for blockchain and its application in intellectual property protection

Blockchain has received a lot of attention recently for its characteristics of decentralization, immutability, traceability, etc., making it a promising technology for the development of various applications, especially the management of various digital information. However, most current blockchain systems exhibit problems such as high computational overhead and centralization of power. Reliance on cryptocurrency in many public blockchain-based applications is another factor that has hindered the application of blockchain technology in areas other than the financial sectors. This paper proposes a new blockchain consensus mechanism based on the contributions of participants. The proposed consensus mechanism, which is called proof-of-contribution (PoC), quantifies user behaviors and actions in a blockchain-based application as contribution values calculated through an algorithm. The node that has the highest contribution value in each round of consensus gets the right to generate the next new block. PoC preserves the properties of decentralization and resistance to hard fork and does not rely on cryptocurrency, making it attractive over cryptocurrency-based consensus mechanisms like proof-of-work (PoW) for a wide variety of applications that do not have to involve cryptocurrency. Contribution values can be abstracted from applications and used in the underlying blockchain consensus process to improve the security and trustworthiness of the applications. Intellectual property (IP) protection is one such application to apply the blockchain technology and the PoC consensus mechanism. However, existing blockchain-based IP protection systems are mostly developed based on public blockchain platforms such as the Ethereum while some others are developed as consortium blockchains, thus exhibiting inherent defects such as high system requirements, long consensus delay, and low user participation. In this paper, we will use IP protection as the application scenario to illustrate the development of our PoC consensus mechanism and will compare PoC to some existing consensus mechanisms. Experimental results will show that the proposed PoC consensus mechanism preserves most of the main security characteristics of blockchain and is superior to existing consensus mechanisms, making it more secure and efficient to use blockchain technology for digital information management.

Digital reading in a second or foreign language: A systematic literature review

This systematic literature review focuses on digital reading in a second or foreign language. The reviewed literature (N = 31, published between 2008 and 2020) revealed several characteristics of second language digital reading environments, tasks, and readers. First, characteristics of digital environments were availability and choice of authentic texts, degrees of linearity, lay-out characteristics, and integrated tools. Second, task characteristics evolved around different reading purposes, navigating elements, and features of digital texts, information management, and interaction. And third, reader characteristics included language and reading proficiency levels; readers' perceptions of their self-efficacy, locus of control, and of themselves as second language readers; and readers' topic, lexical, and world knowledge. These characteristics seemed to enhance motivation, interaction, and understanding, but posed challenges as well, by demanding additional skills, strategies, time, memory capacity, and concentration. The literature provided divergent insights about digital reading strategy use. The consensus seemed to be that the more one reads in a digital environment in the second language, the more digital reading strategies are used. However, increases in strategy use did not necessarily result in better reading comprehension. This review also revealed discrepancies between perceived and actual strategy use, and between teachers' expectations of strategy use and students' actions. We found that educational contexts were being represented more frequently than others. The research was predominantly explorative and qualitative. Based on these findings, recommendations for future research were made. We recommend a clearer focus on the unique aspects of reading in a second language, on the affordances of digital reading, and on the teachers' perspective. In order to move the research on digital reading in a second language forward, we would also advocate a wider scope and more diversity in research designs.

Risk Detection in Digital Information Management: A Records Management Perspective

The Presidential Regulation on e-Government in 2018 became the starting point for accelerating e-Government implementation in Indonesia. This moment prompted government agencies to compete in digitizing their organizations to apply the regulation. Digital information as the output of this massive digitalization will be abundant and must be managed properly which is certainly vulnerable to threats. Such threats can compromise the authenticity of records and make them untrustworthy. An adequate risk detection framework that fits the context of the digital environment is needed to minimize these incidents. This framework contains a records management perspective that has undergone a paradigmatic shift. This framework adopts the view that records management is an integral part of digital information management. The study used a qualitative method and found that from the perspective of records management, the risk detection framework in digital information management sheds light on aspects of context (external and internal), systems, and processes. However, its smooth implementation in the digital environment, especially in Indonesia, is determined by the extent to which paradigmatic reforms in records management have taken place.

Construction 4.0 and ISO 19650: a panacea for the digital revolution?

Construction 4.0 is, at its heart, centred around greater digitisation. The ISO 19650 series is the result of 4 years of development and is a game changer in standardising the process of digital information management. It is being actively implemented across the world, from Europe to Australia, but does it progress or hinder the agenda of Construction 4.0 or does it sit outside that movement? This paper provides a critical analysis of the operation of the ISO 19650 series in addressing the legal and contractual impacts of the digitisation of information management. It also considers the related consequences of the legal community’s continuing struggle to understand the consequences and meaning of digital information management and considers how progress can be made in this area.

The analysis the use of intelligent electric networks and Smart Grid systems

Currently, much awareness is paid to the effects of smart grids on efficiency of power systems and energy districts, and the selection of suitable operating modes for equipment for transmitting electric energy. Modern intelligent networks have an impact on ensuring a stable state of power system operation modes, increasing their reliability in operation, and increasing the quality of electric energy. The article analyzes the use of intelligent electrical networks and intelligent network systems in both Western countries and the Russian Federation. Statistical data on electricity consumption and forecast values for this rate of consumption are given. In the future, until 2020-2025, there will be a gradual transition to a new type of electric grid organization - smart grids. The use of electric power systems in conjunction with innovative digital information management systems will significantly change the technical and economic characteristics of future power systems in a positive way. The comparison of technical parameters of traditional and intelligent electric networks, as well as the classification of the main groups of devices controlled (flexible) by AC power transmission systems is carried out. Systems are divided according to the principle of power regulation. Implemented projects of using flexible alternative current transmission system devices in the world are presented. As a result of the analysis, it was found that China is actively developing managed (flexible) AC power transmission systems, with a large amount of investment from the state, the volume of investment is much larger and amounts to about $ 70 billion per year.

Current status of universal newborn hearing screening program at 26 institutions in China

ObjectivesThe present study aimed to determine the status of a universal newborn hearing screening (UNHS) program being conducted in parts of China, by comparing differences in the program findings between 2016 and 2017, as well as across regions in China. MethodsThis study investigated a nationally representative sample of newborns from 26 provinces, autonomous regions, and municipalities in mainland China. A ‘‘Newborn Hearing Screening Survey’’ questionnaire was sent to 43 hearing screening institutions throughout China and the data were analyzed, with appropriate quality control throughout the study process. ResultsTwenty-six questionnaires, covering 55.88% (19/34) of the provincial administrative regions in China were appropriately completed. The overall sampling frame comprised 238,795 (year 2016) and 229,185 (year 2017) newborns, respectively. We found differences between two years, the initial screening coverage in 2017 (96.10%) was higher than that in 2016 (94.96%); the referral rate at initial screening in 2017 (9.21%) was lower than that in 2016 (10.26%); and the rescreening rate in 2017 (73.50%) was higher than that in 2016 (68.44%). We found differences across three regions, the rescreening rate were highest in West China, the referral rate at rescreening and the referral rate to diagnostic audiological assessment diagnosis were both highest, while the hearing-loss rate was lowest, in the East China in two years. Overall, 61.54% (n = 16) reported using otoacoustic emissions (OAEs), while 38.46% (n = 10) reported using OAEs in combination with automated auditory brainstem response (AABR) tests, for the initial screening. For rescreening, most sites (n = 19, 73.08%) reported using OAEs in combination with AABR, followed by OAEs only (n = 4, 15.38%) and AABR only (n = 3, 11.54%). Of the twenty-six institutions, 57.69% (n = 15) were equipped with a digital information management system for UNHS program, East China had the highest rate of it (81.82%, 9/11). ConclusionsThis study indicated that implementation of a UNHS program had essentially been achieved in many regions of China under the guidance of technical specifications for newborn hearing screening. Compared with 2016, the overall quality of the UNHS program had improved in 2017 and that in East China was better than in the Midland and West China. However, national quality control of the UNHS program is still required to enhance the quality of the program and public education needs to be emphasized to improve the rescreening and reception rate.

THE ISSUE OF “CULTURAL AMNESIA” IN THE CONTEXT OF DIGITAL CULTURAL HERITAGE MANAGEMENT

The issue of the dual impact of innovative technologies on the sphere of spiritual culture has been considered. On the one hand, the digitalization of cultural values gives hope for their longevity, compared with traditional storage methods. On the other hand, the preservation of cultural heritage is facing new, previously unmet difficulties: the life of digital documents is short due to constant technological improvement and the rapid obsolescence of technology; not all artifacts can be digitized; when knowledge is transmitted through the media, its reduction, vulgarization occurs; finally, the person is changing, for whose sake the preservation of the cultural heritage takes place. Generations possessing clip thinking will have to deal with the fragmented, unsystematic cultural heritage, which is fraught with real cultural amnesia. The new approaches to digital information management and, specifically, digital cultural heritage have been proposed in the article.

A digital information system for cultural landscapes: the case of Slender West Lake scenic area in Yangzhou, China

The rapid development of digital technologies provides important opportunities for more effective cultural heritage conservation and management. While the concept of cultural landscape has been accepted by the academic community in the cultural heritage field for many years, the digital conservation of cultural landscapes still lacks pragmatic guidance. The aim of this article is to explore an approach for building a digital information system to support cultural landscape conservation and management. The Slender West Lake scenic area, a typical cultural landscape in China, was used as an instrumental case study. A geo-database was designed and established to integrate the information of the natural, cultural, tangible and intangible landscape features of Slender West Lake. The digital information system for cultural landscapes provides a more holistic, dynamic and specific cultural perspective on heritage for landscape conservators. The system provides comprehensive information support for heritage conservation, management and interpretation, which are not achievable with conventional tools. This article has expanded the cultural heritage theory by presenting a practical guide for the digital information management of cultural landscapes. The workflow for building a cultural landscape geo-database can be used as a reference for heritage projects in China and other countries.

Integrated railway design using Infrastructure-Building Information Modeling. The case study of the port of Venice

The Infrastructure Building Information Modeling (I-BIM) is a digital information management system utilized in the transport infrastructures construction, becoming increasingly important. BIM modeling aims at bringing improvements to all design stages. The use of BIM modeling will also provide cost reduction and control, increase awareness to data, design information availability and usability in each phase of infrastructure life cycle. Although the advanced modeling of the building components and systems leads to advantages well highlighted by practice and literature, in case of transportation infrastructures a critical analysis could show if this design methodology carries out the same benefits. The limited availability of infrastructure components libraries and the difficulty in assigning parameters to the geometries of the objects (many of them with unique characteristics) have been frequently quoted as main obstacles to the BIM use for the transport infrastructures. With this background, the problem is to understand which BIM-for-building features must be preserved in the production and management practices of each infrastructure model (classes, information exchanges and relationship between the classes and the spatial decomposition). This work is focused on the study of the I-BIM methodologies for the transport infrastructures (in particular railway infrastructures), analyzing a case study related to the port of Venice. The upward trend of goods quantity daily passing through the port infrastructures, led to the need to expand the container loading/unloading ship areas and, at the same time, to find a new and faster goods exit from the port areas, compared to the existing railway infrastructures. The authors developed a pre-feasibility study to identify the railway connection between the new port station and the existing line Padova – Mestre and to evaluate the difficulties and the ripeness of available means for an integrated design with the BIM tools
