ISO 14001 Environmental Standard: Process Approach and Identification of Environmental Aspects and Impacts

Environmental management is the management of activities that may have an impact on the environment. It aims to limit polluting emissions and risks to the environment and to save natural resources. Often unsuspected and therefore without us always realizing it, all economic activities can have a considerable impact on the environment. Indeed, the manufacture of products requires the extraction of raw materials and the use of water and energy. Similarly, activities associated with the manufacturing process, such as maintenance, transportation; all have environmental impacts. The environmental management system is a progress tool that integrates the environmental dimension into an organization’s strategy, leading it to set objectives, achieve and maintain performance through effective management and promotes anticipation (the forecast). There is a multitude of guides allowing self-diagnosis by the organization and which make it possible to make an environmental assessment. ISO 14001 is the environmental management standard (EMS) created by the international organization for standardization. It defines the requirements of a global environmental management system for self-reporting or certification purposes. It is organized in 17 points modeled on quality management, well known for 34 years in the industry. The standard does not establish any absolute requirement for environmental performance, other than a commitment to environmental policy, to comply with legislation and the principle of continuous improvement. Pollution prevention through the identification of the various significant environmental aspects and impacts, which accounted for 70% of the requirements of ISO 14001, is the main environmental improvement point. In addition, since these environmental aspects and impacts can only be identified from the activities, products and services associated with them, this article represents a working method that allows expressing good environmental practices, present in the form of environmental performance indicators that inform in a concentrated and precise manner on the different activities with environmental relevance.

Clinical development of a blood biomarker using apolipoprotein-A2 isoforms for early detection of pancreatic cancer

BackgroundWe have previously reported apolipoprotein A2-isoforms (apoA2-is) as candidate plasma biomarkers for early-stage pancreatic cancer. The aim of this study was the clinical development of apoA2-is.MethodsWe established a new enzyme-linked immunosorbent sandwich assay for apoA2-is under the Japanese medical device Quality Management System requirements and performed in vitro diagnostic tests with prespecified end points using 2732 plasma samples. The clinical equivalence and significance of apoA2-is were compared with CA19-9.ResultsThe point estimate of the area under the curve to distinguish between pancreatic cancer (n = 106) and healthy controls (n = 106) was higher for apoA2-ATQ/AT [0.879, 95% confidence interval (CI): 0.832–0.925] than for CA19-9 (0.849, 95% CI 0.793–0.905) and achieved the primary end point. The cutoff apoA2-ATQ/AT of 59.5 μg/mL was defined based on a specificity of 95% in 2000 healthy samples, and the reliability of specificities was confirmed in two independent healthy cohorts as 95.3% (n = 106, 95% CI 89.4–98.0%) and 95.8% (n = 400, 95% CI 93.3–97.3%). The sensitivities of apoA2-ATQ/AT for detecting both stage I (47.4%) and I/II (50%) pancreatic cancers were higher than those of CA19-9 (36.8% and 46.7%, respectively). The combination of apoA2-ATQ/AT (cutoff, 59.5 μg/mL) and CA19-9 (37 U/mL) increased the sensitivity for pancreatic cancer to 87.7% compared with 69.8% for CA19-9 alone. The clinical performance of apoA2-is was blindly confirmed by the National Cancer Institute Early Detection Research Network.ConclusionsThe clinical performance of ApoA2-ATQ/AT as a blood biomarker is equivalent to or better than that of CA19-9.

Abstract B007: Early detection and risk stratification of pancreatic cancer using apolipoprotein A2-isoforms as a blood biomarker

Abstract To reduce the mortality rate of pancreatic cancer, there is an urgent need to develop a biomarker that can efficiently screen for pancreatic cancer in blood tests. We had identified the unique processing of C-terminal amino acids of apolipoprotein A2 homodimers, we named it apolipoprotein A2-isoforms (apoA2-i). ApoA2-i consists of three isoforms with different C-terminal amino acids. Especially, we had reported that apoA2-ATQ/AT, known as the intermediate isoform, was significantly reduced in the bloodstream of pancreatic adenocarcinoma (PDAC) patients compared to healthy controls. However, previous reports were investigated using a research use only (RUO) reagent, which could not be used in clinical settings. We generated a novel ELISA for measuring apoA2-i under the Japanese medical device Quality Management System requirements, and measured the concentration of apoA2-i in 2,732 of plasma samples. The clinical equivariance and significance of apoA2i were evaluated by pre-specified endpoints. The point estimate of the area under the curve to distinguish between PDAC and healthy controls was higher for apoA2-ATQ/AT [0.879, 95% confidence interval (CI): 0.832–0.925] than for CA19-9 (0.849, 95%CI: 0.793–0.905) and achieved the primary endpoint. The cut-off apoA2-ATQ/AT of 59.5 μg/mL was defined based on 95% specificity in 2,000 healthy samples. The sensitivity of apoA2-ATQ/AT for detecting both stage I (47.4%) and I/II (50%) of PDAC was higher than that of CA19-9 (36.8% and 46.7%, respectively). The combination of apoA2-ATQ/AT (cut-off, 59.5 μg/mL) and CA19-9 (37 U/mL) increased the sensitivity for pancreatic cancer to 87.7% compared with 69.8% for CA19-9 alone. ApoA2-ATQ/AT has equivalent or better clinical performance to CA19-9 as a blood biomarker. Citation Format: Kazufumi Honda, Ayumi H.

Establish and Implement PAM and PRM ISO 20000-1:2011

Most enterprises are now using information technology services as their assets to support business objectives. These kind of services are provided by internal service provider (inside enterprise) or external service provider (outside enterprise). To deliver quality information technology services, service provider (which from now on will be called “organization”) either internal or external, must have standard for service management system. At present, the standard that is recognized as best practice for service management system for organization is international standard ISO/IEC 20000:2011. The most important part of this international standard is the first part or ISO/IEC 20000-1:2011-Service Management System Requirement, because it contains 22 for organization processes as requirement to be implemented in organizational environment in order to build, manage and deliver quality service to customer. Assessing organization management processes is the first step to implement ISO/IEC 20000:2011 into the organization management processes. This assessment needs Process Assessment Model (PAM) as assessment instrument. PAM comprises two parts: Process Reference Model (PRM) and Measurement Framework (MF). PRM is built by transforming the 22 process of ISO/IEC 20000-1:2011 and MF is based on ISO/IEC 33020. This assessment instrument was designed to assess the capability of service management process in Divisi Teknologi dan Sistem Informasi (Information Systems and Technology Division) as an internal organization of PT Pos Indonesia. The result of this assessment model can be proposed to improve the capability of service management system.

In order to simplify the implementation of such systems, standards for basic functionalities that should be part of basic configurations of PDMS would be of great value. This paper describes functional requirements for PDMS in several categories. Criteria for standardized data documentation were defined by the authors and derived functional requirements were classified into two priority categories. Overall, general technical requirements, functionalities for intensive care patient care, and additional functionalities for PDMS were defined and prioritized. Using this paper as astarting point for adiscussion about basic functionalities of PDMS, it is planned to develop and obtain consensus on definitive standards with representatives from medical societies, medical informatics and PDMS manufacture.

Management Approaches to Health and Safety at Work during Prevention Intervention Planning.

This work deals with a systematic review of the literature data concerning the theme of integrated approaches to occupational health and safety management, with particular reference to the programming of assistance plans, which guide companies' organizational choices by also addressing the principles of Total Worker Health. In the current regulatory framework on this issue, the UNI ISO 45001: 2018 standard "Occupational health and safety management systems-Requirements and guidance for use" (published on 12 March 2018)" assumes relevance, defining dynamic approaches to occupational health and safety management systems-paying particular attention to external contextual factors that may influence corporate organizational decisions. The adoption of these systems is not mandatory but allows companies to fulfill their duties in terms of health and safety at work through an organizational approach aimed at the awareness, involvement, and participation of all subjects of the company prevention system, progressing past the phase of mere technological and prescriptive approaches towards a holistic vision of prevention that places the person at the center of preventive actions. In this context, the role of institutional networks and socio-economic partnerships assumes particular importance via the activation of territorial assistance interventions to support companies aimed at improving risk management levels. To this end, the importance of verifying the effectiveness of assistance interventions emerges from the scientific debate using indicators such as quantitative indicators aimed at measuring the performance of all phases of an intervention, with particular attention to their effects in terms of the improved solutions developed.

System identification and state estimation of a reduced-order electrochemical model for lithium-ion batteries

Lithium-ion batteries commonly used in electric vehicles are an indispensable part of the development process of decarbonization, electrification, and intelligence in transportation. From intelligent designing, manufacturing to controlling, an intelligent battery management system plays a crucial role in the long life, high efficiency, and safe operation of lithium-ion batteries. As a first-principle model, the electrochemical parameters of the electrochemical model have physical meanings and reflect the internal state of the lithium-ion batteries. The application of electrochemical models in an advanced intelligent battery management system is a future trend that promises to mitigate battery life degradation and prevent safety incidents. The reduced-order electrochemical model is expected to alleviate the requirements of advanced battery management systems for high accuracy and fast computing of lithium-ion battery models. However, the existing model order reduction methods have the drawbacks of high computational complexity and small application scope, so that inconvenient to apply onboard. In order to solve the existing obstacles, this paper applies the pseudo-spectral method to solve the solid-phase diffusion equation, while the liquid-phase concentration equation is simplified by the Galerkin method. Subsequently, a particle swarm optimization algorithm is used to identify 11 parameters of the electrochemical model. To further improve the accuracy of the electrochemical model, the above system identification method is applied to segment identification, especially for high or low state-of-charge (SoC) conditions in this study. Finally, based upon the derived model, estimation of SoC is performed using a particle filter. The results show that the proposed reduced-order electrochemical model achieves a low Mean Absolute Error (MAE) of 8.4 mV and a MAE of 0.54 % on estimation of SoC based on the envisaged particle filter. This work is expected to provide the basis for the subsequent development of lithium-ion battery electrochemical models with smaller identification parameters and faster identification processes.

Cloud-edge Collaboration Based Methods in Improving the Safety Inspection Efficiency on Electric Operation Scenes

The safety in electric operation scenes directly influences social economic development and stability. Safety supervision and inspection is one of the most important links in the electricity generation process. The previous mode of executing supervision and inspection in advance and analyzing and reporting afterwards cannot satisfy the requirements of the modern management system, which requests beforehand prevention, in-process control, post review, and analysis. The supervision and inspection efficiency is low. Therefore, this paper proposed three innovative methods to increase the supervision and inspection efficiency of the electric operation. First, we proposed an operation demonstration method on electric equipment that integrates with Augmented Reality (AR). It can greatly increase the operating accuracy and decrease the probability of accidents. Then, a smart, mobile, and cloud-edge collaborated method is proposed, aiming at increasing the availability and effectiveness of safety supervision and inspection. Last, we adopted technical means of integrative recognition to increase the efficiency of obtaining evidence on inspection.

Battery States Monitoring for Electric Vehicles Based on Transferred Multi-Task Learning

State/temperature monitoring is one of the key requirements of battery management systems that facilitates efficient and intelligent management to ensure the safe operation of batteries in electrified transportation. This paper proposes an online end-to-end state monitoring method based on transferred multi-task learning. Measurement data is directly used for sharing information generation with the convolutional neural network. Then, the multiple task-specific layers are added for state/temperature monitoring. The transfer learning strategy is designed to improve accuracy further under various application scenarios. Experiments under different working profiles, temperatures, and aging conditions are conducted to evaluate the method, which covers the wide usage ranges in electric vehicles. Comparisons with several benchmarks illustrate the superiority of the proposed method with better accuracy and computational efficiency. The monitoring results under extremely current working profiles and variable internal and external conditions are evaluated. Results show that the mean absolute error and root mean square error of state of charge and state of energy estimation are less than 2.31% and 3.31%, respectively. The above errors in the prediction of future temperature five steps ahead are less than 0.89℃ and 1.29℃, respectively. The framework is also suitable for monitoring second-life batteries retired from electric vehicles. This paper illustrates the potential application of data-driven multi-state monitoring throughout the entire battery life.

Measuring the availability of the requirements of the quality management system (ISO 9001:2015) clause leadership, performance, and planning: a case study

The study aims to identify the application of the criteria of a quality management system as defined by an international standard ISO 9001:2015. It analyzes the gap between the actual reality and the requirements of the specification that would raise the level of performance, preparing the selected factory to obtain a certificate of conformity with the specifications of the global standard ISO 9001:2015. This is achieved through identifying the strengths and weaknesses of the system, diagnosing the gap and finding ways to address such a gap. This study selected one of the prefabricated building factories which belongs to the Iraqi Ministry of Construction and Housing as the sample of the study. The data were collected using three methods, namely, field visits, records and documents and checklists. The collected data were, then, analyzed using percentages and weighted arithmetic means. The findings revealed that the application of the quality management system in the prefabricated building factory was estimated to be at 67.14%, which is close to being partially implemented and partially documented. This indicates there is a gap of about 32.86%; such a gap can be addressed through continuous improvement, management review of the system, problem-solving, and the documentation of some requirements.

Review of Occupational Health and Safety Management System and Hazards Controls in the Motion & Industrial Automation Products Manufacturing Industries

Occupational injuries are a major problem worldwide and affect all countries, particularly developing ones. In recent decades, the application of approaches such as the Occupational Health and Safety Management System (OHSMS) has led to the successful control of workplace injuries in high-income countries. The Occupational Health and Safety Assessment Series (OHSAS) 18001 as a world- recognized OHSMS has gained considerable acceptance by a large number of organizations. However, few studies have examined the effectiveness of ISO 45001on safety performance in certified organizations. This study consisted of four sub-studies, and was conducted to explore the effect of ISO 45001on the occupational injury, safety climate, and Occupational Health and Safety (OHS) practices in ISO 45001-certified companies compared with a control group in Iran. ISO 45001practices were also examined in the certified companies, where interviews were conducted to explore the influencing factors on the effectiveness of ISO 45001. A negative binomial regression indicated no significant effect of ISO 45001certification on the occupational injury rate. The second sub-study applied a new safety climate questionnaire, and a hierarchical regression indicated that the safety climate was influenced by the implementation of ISO 45001and safety training. The third sub-study pointed to the better OHS practices of the certified companies compared with the control ones. The results also showed that adopting the ISO 45001standard improved the documentation for the management of OHS, but did not lead to continuous improvement in the required practices. The evaluation of the collected evidence revealed the main reasons for a poor safety culture. The interviewees emphasized the internal and external influencing factors in the effectiveness of OHSAS including commitment of top management and the enforcement of OHS legal requirements. It can be concluded that the implementation of ISO 45001in an organization is not a guarantee of improved safety performance and of the existence of a high-quality management system. This study suggests that certified companies should focus on proper improvement and maintenance of the implemented management systems by escalating their commitment to the requirements of the established management systems and by participating their employees in ISO 45001practices. This study also emphasized the importance of providing safety training for employees who work in the certified companies. These efforts may help the companies in the creation of a good safety culture and the transforming the paper systems into effective management systems to make improvement in OHS performance. The aim of this report to assess and evaluate the effective implementation of occupational health & management system and hazards controls in the Motion & Industrial Automation products manufacturing Industries as per the relevant ISO standards and hierarchy of hazards controls, which is a system used in industry to minimize or eliminate exposure to hazards. Falls, chemical spills, fire, explosions, working at height, confined space working, mechanical material handling, etc. are few kinds of incidents that can happen in a manufacturing environment. Such incidents are not only tragic and frequently fatal for workers, but also extremely expensive for the employers. Between worker’s compensation, regulatory penalties, reduced/diminished productivity and the costs of fixing or replacing damaged equipment, a single incident can financially devastate a business. To avoid industrial accidents / catastrophes, keep your people from harm, ensure manufacturing compliance, and protect your bottom line, you need to get serious about safety. Manufacturing Safety is everything organizations does to ensure the physical well-being of the workers in the manufacturing facility or facilities. Manufacturing Safety is also about more than checking a few boxes or putting up ‘safety first’ signage.  Manufacturing Safety keeps people alive and unharmed.  Manufacturing Safety is also tied to workforce productivity.  Manufacturing Safety is an essential form of risk management.  Manufacturing Safety is a legal requirement.  Manufacturing Safety and Profitability go hand-in-hand. Safe companies perform better and sustain in the business longer that unsafe companies.

A global blockchain for recording high rates of COVID-19 vaccinations

Blockchain has been recently proposed to securely record vaccinations against COVID-19 and manage their verification. However, existing solutions may not fully meet the requirements of a global vaccination management system. These requirements include the scalability required to support a global vaccination campaign, like one against COVID-19, and the capability to facilitate the interoperation between the independent health administrations of different countries. Moreover, access to global statistics can help to control securing community health and provide continuity of care for individuals during a pandemic. In this paper, we propose GEOS, a blockchain-based vaccination management system designed to address the challenges faced by the global vaccination campaign against COVID-19. GEOS offers interoperability between vaccination information systems at both domestic and international levels, supporting high vaccination rates and extensive coverage for the global population. To provide those features, GEOS uses a two-layer blockchain architecture, a simplified byzantine-tolerant consensus algorithm, and the Boneh–Lynn–Shacham signature scheme. We analyze the scalability of GEOS by examining transaction rate and confirmation times, considering factors such as the number of validators, communication overhead, and block size within the blockchain network. Our findings demonstrate the effectiveness of GEOS in managing COVID-19 vaccination records and statistical data for 236 countries, encompassing crucial information such as daily vaccination rates for highly populous nations and the global vaccination demand, as identified by the World Health Organization.
