Occupational Health and Safety in China: A Systematic Analysis of Research Trends and Future Perspectives

The frequent occurrence of various occupational accidents has resulted in significant casualties and occupational disease issues, which hinder economic and social development seriously. The promotion and enhancement of occupational health and safety (OHS) require greater efforts to be made to achieve sustainable economic development, particularly in developing countries. With remarkable progress and achievements that have been made in terms of OHS in China, a systematic and thorough review is needed to gain insight into the development process, current status, and research trends regarding OHS in China. Additionally, pathways for future work need to be discussed to boost the OHS development in China in the new era. Therefore, a systematic literature review is performed in this study to investigate the development of OHS in China with the help of a bibliometric analysis. Firstly, a total of 5675 publications related to OHS in China between 1979 and 2022 were collected from the Web of Science Core Collection (WoSCC) and the Chinese Science Citation Database (CSCD) before being refined manually. Then, the temporal distribution and journal sources of the collected publications were analyzed before the collaboration networks of the “productive institutions” and “productive authors” were discussed. Furthermore, the key research topics (e.g., disease prevention, psychological safety, occupational exposure) and dominant research methods (e.g., epidemiological methods, risk modeling) associated with OHS during different periods were identified and discussed based on the keywords and bibliographic analysis. Finally, the current needs and promising pathways for future work were discussed. It is suggested that the prevention and control of conventional and new occupational diseases, the protection of workers’ occupational health rights and interests, the development and implementation of advanced technologies for OHS, and the development of more sophisticated and efficient health and safety risk assessment models may be focused on to accelerate the development of OHS in China. This study systematically reviews the development processes, current status, and future prospects regarding OHS in China. The results of this study provide valuable insights for researchers and practitioners who are involved in the Chinese OHS development, and the promising pathways for future works are suggested to boost the OHS development in China.

Strategic Objectives of Sustainable Development Model in Production and Education

Purpose: The research aims to create a general economic-geographical model and explore its application possibilities using various criteria to achieve sustainable development in production and education. Introducing a new model is one of the most critical conditions since scientific research in this direction only partially solves the problem. In this regard, creating an economic-geographical model in production and education is very important. The model can positively affect the regulation of mutual relations of any economically developed countries with a favourable geographical position.
 
 Theoretical framework: The model we have presented can be applied from a theoretical point of view in creating new production areas, increasing personnel potential, and improving the quality of education. However, there is a need to conduct scientific research in this direction. Because in order to achieve the principles of stable and sustainable development in production and education, a favourable and accessible environment must first be formed so that people's social well-being and quality of life can reach a high level of development. Nevertheless, all forms of education provide us with a wealth of experience and information related to various scientific fields, as well as an understanding of the wider world and human interactions.
 
 Design/methodology/approach: From a methodological point of view, several scientists and specialists deal with ways of developing production and education and their application mechanisms. In this direction, we approached the scientific works of N.A.Iskakov, L.N.Rodionova, Y.I.Vaisman, R.Jovovic, M.P.Todaro, Z.T.Imrani and others, their ideas and scientific results from a synergistic point of view. Besides these, there are different methods of approach in the field of production and education. Grouping methods were used: event, fact, cause and effect, as well as a deduction, systematic study of objects, synthesis of events and processes, characterizing production and education, comparison in determining optimal options, generalization, establishing interaction and in preparation of the model.
 
 Findings: In our modern times, economic power reflects the social and ecological components and the ability to produce products. In addition to production, this potential includes scientific and technical achievements and the level of education. The economic-geographical model of sustainable development in production and education can have different directions, but its advantage is related to meeting the minimum needs of people in the future by achieving complex development.
 
 Research, Practical & Social implications: The economic-geographical model presented in the field of production and education can help to focus on many ideas based on political, economic, social as well as environmental sustainability at the local, regional and global levels. Geographical development is not only natural but also can lead to the solution of economic problems.
 
 Originality/value: Aerospace, electronic, microbiological, biochemical and other fields, which have the latest scientific achievements and are equipped with technological equipment, occupy the most essential place in modern production. However, the most critical changes in the economy are related to the advanced development of professional services, information technology and scientific research. In this regard, the value of the research will be a foundation for undergraduate and graduate students, and the application of the model will allow for the exploration of many theories and applications of sustainable development in urban and rural areas.

PERANCANGAN APLIKASI PERHITUNGAN IURAN BPJS REMUNERASI RSUD KOTA SALATIGA UNTUK ASN BERBASIS DEKSTOP

In the era of increasingly advanced technological development there are many supporting factors in supporting change or innovation from all aspects. The development of a technology really helps human work in various ways. All fields, both government and companies, have used technology in carrying out every service and business process, and technology itself has become an important and needed thing in all these fields. Currently the Salatiga city Diskominfo in collaboration with the Salatiga city hospital is making changes in the process of calculating the BPJS contributions to hospital employees, the old manual process has been changed into a form of a desktop-based application system, because the data input process is still done manually. many employees do not pay the BPJS contributions. Because the Salatiga City Hospital wants to take advantage of technology that is growing and does not require a lot of human resources to run the application. To create a desktop-based application system, a supporting framework is needed, namely the Delphi 10.4 Community Edition framework. This framework is very useful for programmers who will make an application because the template provided is very easy to understand so that programmers can easily make the application. This desktop-based application that was created can later make it easier for admins to manage input output data so that it becomes easier and more efficiently.

Prediction of urban residential energy consumption intensity in China toward 2060 under regional development scenarios

With global commitments to carbon neutrality, restraining the rapid growth of building energy consumption becomes crucial. Several building energy consumption predictions for China were conducted, but the regional heterogeneity and urban residentials’ special characteristics were not considered in these models. Thus, a “bottom-up” physical model with regional scenario assumptions was proposed for existing, newly-built, and renovated urban residential energy consumption prediction in five building thermal zones in China. Large-scale investigations were conducted for regional energy-use status and energy-use-related advanced technology development status both in China and developed countries. Regarding building envelope thermal properties, types, possession quantities, and performance of energy-use equipment, occupant energy-use behavior, and renewable energy utilization, Benchmark (B), Medium control (M), and Strict control (S) scenarios were assumed considering the spatial differences among each zone and temporal difference between 2020 and 2060. Results showed fluctuating trends, but all zones peak in 2035 under the B scenario, and before 2025 under the M and S scenarios. The intensity for newly-built urban residentials under the S scenarios in Severe cold, Cold, Hot Summer and Cold Winter, Hot Summer and Warm Winter, and Mild zones by 2060 are 4.07 kgce/(m2·a), 6.8 kgce/(m2·a), 6.53 kgce/(m2·a), 6.5 kgce/(m2·a), and 5.21 kgce/(m2·a), respectively.

Envisioning a better world of human and technology: theoretical and empirical considerations to connect communication scholarship to ethical technology design

ABSTRACT With the artificial intelligence and robotics revolution transforming science and society rapidly, ethical issues surrounding the development and use of advanced technologies are causing concerns worldwide. Despite communication scholars being well-positioned to tackle issues relevant to ethical technology development, we have conducted little research to inform and critique this space. This paper aims to advocate for better knowledge and approaches in ethical technology design and communication scholarship, and encourage communication researchers to contribute to technology design by leveraging communication expertise and borrowing scholarly insights from other fields. Specifically, we introduce foundational feminist technoscience theories and relevant technology design approaches, propose seven core design principles to aid communication research, and discuss how communication scholarship can benefit the space of technology.

How Smart are Smart Materials? A Conceptual and Ethical Analysis of Smart Lifelike Materials for the Design of Regenerative Valve Implants.

It may soon become possible not just to replace, but to re-grow healthy tissues after injury or disease, because of innovations in the field of Regenerative Medicine. One particularly promising innovation is a regenerative valve implant to treat people with heart valve disease. These implants are fabricated from so-called 'smart', 'lifelike' materials. Implanted inside a heart, these implants stimulate re-growth of a healthy, living heart valve. While the technological development advances, the ethical implications of this new technology are still unclear and a clear conceptual understanding of the notions 'smart' and 'lifelike' is currently lacking. In this paper, we explore the conceptual and ethical implications of the development of smart lifelike materials for the design of regenerative implants, by analysing heart valve implants as a showcase. In our conceptual analysis, we show that the materials are considered 'smart' because they can communicate with human tissues, and 'lifelike' because they are structurally similar to these tissues. This shows that regenerative valve implants become intimately integrated in the living tissues of the human body. As such, they manifest the ontological entanglement of body and technology. In our ethical analysis, we argue this is ethically significant in at least two ways: It exacerbates the irreversibility of the implantation procedure, and it might affect the embodied experience of the implant recipient. With our conceptual and ethical analysis, we aim to contribute to responsible development of smart lifelike materials and regenerative implants.

Compositional Tuning of Nickel Sulfoselenides for Use As Bifunctional Oxygen Electrocatalysts in Aqueous Electrochemical Energy Storage

Increasing grid-scale deployment of intermittent energy sources necessitates the development of advanced energy storage technologies. Electrochemical energy storage technologies using alkaline electrolytes, especially secondary Zn-air batteries, are uniquely suitable, using inexpensive, non-flammable aqueous electrolytes and making extensive use of earth abundant elements (C, Zn, Mn, etc.). Unfortunately, development of Zn-air batteries is currently limited by electrochemical challenges at both the Zn anode and the air cathode, with the limitations at the air cathode being particularly complex. An ideal cathode would use a bifunctional oxygen electrocatalyst (BOE) capable of efficiently and sequentially catalyzing both the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Precious metal-containing materials (Pt, RuO2, etc.) are currently the most efficient BOEs, but their high cost makes them unideal for commercialization. Transition metal chalcogenides (e.g., NiS2, Ni3Se2) have previously been used as BOEs, but are still relatively underdeveloped alternatives to precious metal electrocatalysts.In this presentation, we report the electrocatalytic performance of a series of compositionally-tunable nickel sulfoselenides (Ni3(S,Se)2, NiSSe) for use as BOEs in Zn-air batteries in place of existing precious metal electrocatalysts. These materials have previously shown promise as OER electrocatalysts, but their ORR and BOE performance has not yet been explored. We demonstrate the synthesis of a range of NiSSe materials with variable S/Se composition, and subsequently use multiple characterization techniques, including cyclic voltammetry, X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), and others, to explore the performance of these materials as BOE electrocatalysts. The nanoscale NiSSe materials show homogeneous mixing of S/Se over a wide compositional range (10-90% Se), and electrocatalytic testing shows that this S/Se composition has an observable impact on the OER/ORR performance. Roughly 50/50 mixtures showed the best OER performance, while pure Ni3Se2 showed the best ORR performance. As a result, optimum BOE performance of the mixed NiSSe materials was observed near a composition of Ni3S0.4Se1.6; the (electro)chemical stability of this mixed NiSSe was subsequently evaluated using chronoamperometry and XPS. Compared with the binary Ni3S2 and Ni3Se2 compounds, NiSSe was found to be reasonably stable after testing and is therefore a promising candidate for use in air cathodes. As a demonstration, we then tested this NiSSe electrocatalyst in a Zn-air battery and found good agreement with the results from previous the Zn-free experiments. Together, our results show that nickel sulfoselenides are a promising class of tunable electrocatalysts with applications in oxygen electrocatalysis for energy storage.This work was supported by the U.S. Department of Energy, Office of Electricity, and the Laboratory Directed Research and Development program at Sandia National Laboratories, a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-NA-0003525.

Degradation Analysis of SOFC Performance for Long-Term Operation with High Fuel Utilization (2)

Solid oxide fuel cells (SOFCs) are a power generation technology with its high efficiency and low environmental impact, and the most important issue for SOFC for practical use is to improve reliability as well as high efficiency. A national project on SOFC development in Japan, “Development of advanced evaluation and analysis technologies for the durability of Solid Oxide Fuel Cells stacks (2020-),” has been initiated as a NEDO project in order to clarify their long-term durability and find dominant degradation factor for each SOFC stacks. Central Research Institute of Electric Power Industry (CRIEPI) has operated three kinds of different SOFC cell/stacks (flat-tubular and two kinds of planer) for durability under NEDO’s project, which have been developed by KYOCERA, MORIMURA SOFC Technology, and DENSO.Long-term durability tests of 20,000 hours have been conducted under high fuel utilization of 80% and 85%, which is close to the operating limit of each SOFC cell/stack for high efficiency, to evaluate the effects on the performance and degradation behavior of the cell/stack. In previous projects, we have developed an electrode polarization model that can accurately represent SOFC performance, including cell voltage and each overvoltage, under a variety of conditions. The degradation factors for durability of each SOFC cell/stack have been analyzed by using this model. The analysis revealed that the dominant degradation factors were increased cathode overvoltage and IR loss, similar to the SOFC cell/stacks that were modified from the previous project to improve their long-term durability. On the other hand, the degradation rate of cell voltage was higher at 85% than at 80% fuel utilization in one cell/stack, and the performance degradation factor analysis revealed that this difference was due to an increase in anode overvoltage at 85% than at 80% fuel utilization, where anode overvoltage was not the primary degradation factor.This work has been carried out under the projects (JPNP13001 and JPNP20003) of the New Energy and Industrial Technology Development Organization (NEDO), Japan as contract research. We would like to express our gratitude to NEDO, many SOFC developers, as well as to university partners and National Institute of Advanced Industrial Science and Technology (AIST).

Demand oriented planning of methanol-dimethyl ether co-production system for CO2 reduction

This work addresses an optimal design method for a methanol-dimethyl ether co-production system with the fluctuations in supply and demand, aiming to utilize the CO2 from point sources as much as possible in actual industries. In the proposed method, a design and optimization model of the chemical co-production system is established with the aim of the lowest total annualized cost, and rigorous simulations are conducted to determine the cost flows of the operation units in the system. The optimal design, operation, and scheduling schemes of the co-production system can thus be determined by solving the proposed model. The application of the method is finally verified via an actual case study where a 330 MW off-design thermal power plant is taken as the carbon source and the product demand and price are determined according to the market. Results showed that the renewable chemical co-production system features the advantages of coping with supply and demand fluctuations by flexibly adjusting the production, storage and sale capacities of the products, thus achieving the maximum economic benefits and carbon reduction efficiency of 94.7%. The electricity consumption for electrolysis is the main contributor to the total annual cost of the system, accounting for more than 70%. Besides, expanding the capacity adjustment range of the dimethyl ether synthesis process can not only improve the ability of the system to deal with economic fluctuations but also help to reduce the capacity of storage tanks. It is foreseeable that the proposed system can be competitive in the near future with the formulation of new policies and the development of advanced technologies.

Coded meta-materials drivened by impedance-mismatch: Ultra-broadband anti-reflection and scattering field manipulation

The inability of existing electromagnetic wave absorbing materials (EAMs) to manipulate electromagnetic waves in multiple dimensions leads to the failure to satisfy the demands placed on electromagnetic (EM) defense technology by the current complex EM environment. To break this dilemma, this study focuses on the impedance properties of EAMs, conferring additional ability to disperse and deflect reflected waves by encoding EAMs with opposite phase responses in different impedance mismatch modes. Due to the synergy of both absorption and scattering mechanisms, the developed scattering metamaterial absorber exhibits excellent anti-reflection performance, with reflectivity below 0.1 in the 7.8–16.7 GHz at 2 mm thickness. Furthermore, a genetic algorithm is employed to tailor the desired scattering field to meet the stealth requirements of specific environments, allowing for the directional transmission of EM energy in the one-dimensional or homogeneous distribution in the three-dimensional. The proposed scattering metamaterial absorber constructed by coded EAMs exhibited excellent anti-reflection properties and environmental stealth adaptability, opening up new possibilities for the development of advanced EM defense technology.

Contactless Method for Measurement of Surface Roughness Based on a Chromatic Confocal Sensor

The methodology for assigning and assessing the surface quality is used at various stages of the product life cycle: during the design and technological preparation of production, the production itself, and during the control (testing) of products. The development of advanced technologies requires in situ part control. A non-contact in situ surface roughness measuring system is proposed in this paper. The proposed system utilizes a chromatic confocal sensor, and profile data, waviness data, roughness data, Ra, and Rz parameters are generated in the developed data-processing software. The assembled measuring system based on the chromatic confocal laser sensor showed its performance in assessing the roughness parameter Ra, from 0.34 µm to more than 12 µm, which covers a common range of milling, turning, and grinding. In this range, measurement relative errors can be controlled within 10%. Frequency analysis and correlation analysis of profilograms were performed. Frequency analysis made it possible to establish the dominant frequency components that occur in the profilogram of the samples, while correlation analysis was used to develop a methodology for identifying the deterministic and random components of the processed surface profile signal. The results of the analysis can be further used to develop diagnostic functions for process monitoring based on profilogram estimates, such as the autocorrelation function and the power spectrum density.

Assisted wet deposition targeted synthesis of Co-N coordination single-atom catalysts for efficient Fenton-like catalytic degradation of micropollutants

Assisted wet deposition methods to localize the active phase metal on the carrier surface and prevent atomic aggregation during conventional heat treatment are strongly preferred. Herein, single-atom cobalt catalysts (SA-Co-PCN) with different metal-central content were target-prepared using a combination of impregnation and secondary annealing on polymerized carbon nitride (PCN) through reticular confinement. Fitting the coordination configuration of the Co-N pathway within the first coordination shell according to quantitative EXAFS indicated that the ligancy of Co-N was 4. The removal efficiency of representative micropollutants in the SA-Co-PCN/PMS system achieved 100% within 15 min. The outstanding degradation properties of micropollutants were ascribed to the SA-Co-PCN boosts PMS to a 1O2-dominated system. Moreover, the effects of substituents on the degradation behavior and ecotoxicology of sulfonamides (SAs) in PMS-activated systems were investigated in depth. The combination of DFT theoretical calculations and LC-MS further confirmed that the similar electron-rich sites on the SAs molecules allowed for commonality in the degradation pathway. Both S-N bond and C-S bond fragments became the initial attack and cleavage sites in the series of SAs. Ecotoxicity predictions indicated that most intermediates of SAs exhibited lower acute and chronic toxicity, especially acute toxicity, than the parent compounds. Environmental ImplicationAssisted wet deposition to localize the active phase metal on the carrier surface allows easy target formation of single-atom cobalt catalysts (SA-Co-PCN), which could boost PMS to a 1O2-dominated system for efficient oxidation of typical micropollutants. The degradation behavior and ecotoxicology of sulfonamides in the SA-Co-PCN/PMS system were investigated in depth, revealing that most intermediates of sulfonamides exhibited lower acute and chronic toxicity, especially acute toxicity, than the parent compounds. This work provides a strategy for the development of facilely prepared single-atom catalysts and contributes to the development and application potential of PMS advanced oxidation technology for water pollution control.

Embodied Bits

The Master research “Embodied Bits” concerns how trans-human, post-digital and post-internet ideas relate to my Queer experience. It is, in a nutshell, an ongoing research on how the technological world has spilled over into the biological world and how Queer folks are front and centre when it comes to taking advantage of technological developments in order to realise their identities. The research question is “How do we perform ourselves in the digital realm?”. Though it started as a research on the practicalities and aesthetics of internet/networked-based performances it quickly opened a Pandora’s Box of social inquiry and analysis. Performing ourselves means performing ethnicity, gender, sexuality, cultural identity... There is an inevitability in drawing a direct connection between these topics and how do we, as singular and, paradoxically, plural human beings within ourselves engage with modern day technology. Through technology we are able to build ourselves, to draft new identities, to build again if they no longer suit our needs. As an artistic research, “Embodied Bits” looks into how digital media has influenced human experience and focuses on the experiences of non-normative bodies and identities, in which I include my own. These topics are interlaced with my own compositional and performative work, always informed and inspired by the previously mentioned ideas and historical context.
