Determination of formation dip and strike from transient LWD electromagnetic measurements

An original method has been developed for estimating formation dip and strike from transient induction LWD data, based on focusing in the time domain. The focusing consists in decomposing the measured signals into a time series and diagonalizing the matrix of focused magnetic field components. We have implemented the method and comprehensively tested it in horizontally-layered media used for LWD data inversion to solve geosteering problems and evaluate the formation resistivity. Estimates of the angles contribute to reliable geosteering when choosing a direction of drilling, as well as when inverting data for a complex earth model. A significant reduction in the resource intensity of inversion and model equivalence is achieved by reducing the number of determined parameters.

Environmental and Economic Prerequisites for Russiaʼs Transition to a Low-Carbon Economy

Introduction. Environmental and climatic problems of the Russian Federation have attracted considerable attention from scientists, politicians, as well as the general public. Human activities are a major cause of pollution and global warming, which necessitates the search for a new way of economic development reducing the adverse impact on the environment. The authors consider a low-carbon economy aimed at simultaneously solving economic, environmental, and climatic problems as such a guideline. Based on the research conducted the article identifies the constituent entities of the Russian Federation in which pilot projects for the transition of enterprises and cities to low-carbon development are most expedient to implement. The gained experience should be applied in other regions of the country in the future. Materials and Methods. Data from the Federal State Statistics Service and the Ministry of Natural Resources and Environment of the Russian Federation on 20 most populated constituent entities of the country were analyzed. In order to identify the regions with the largest volumes of various types of pollution, the data ranking method was applied. The authors have also carried out an analysis of relative indicators of natural resource intensity associated with emission into the atmosphere, discharges of polluted wastewater, and production of municipal solid waste. Results. The performed analysis has shown the heterogeneity of the environmental and economic development of the constituent entities of the Russian Federation. It has been concluded that among the regions considered, it is most expedient to implement pilot projects for low-carbon development in cities and in “polluting” industries located in the Kemerovo, Sverdlovsk, and Chelyabinsk Regions, as well as in the Krasnoyarsk Territory. Discussion and Conclusion. The results of the study can be used in the development of environmental programs, as well as in the development of directions for mitigating the environmental impact in the most polluted regions of the country and in industries with high natural resource intensity.

Improving the methodology for creating a medical service based on the costs of its production

Background. Currently, the multichannel nature of financial flows determines the multivariate methods of payment for medical services, which are also influenced by the type of medical care, conditions, form of its provision, and type of institution. As a result, the cost of a medical service can vary significantly not only in different, but even in one medical organization. The lack of a unified methodological approach puts healthcare organizations in unequal conditions, as a result, public sector medical organizations are forced to seek additional resources to provide medical care to the population that meets the standards. None of the current methods for determining the cost of a medical service reflects its actual cost, since it does not take into account the structure of production costs.The aim. To improve the methodology for the formation of the cost of public services in the health care system, taking into account their resource intensity.Materials and methods. The study included the analysis of the forms of state statistical observation of medical organizations of the Irkutsk region, reports of the federal and regional accounting chambers, industry regulations, materials of scientific periodicals, conferences, monographic studies, including on the Internet; comparison of the cost of medical services in various medical organizations of the Irkutsk region; modeling methods for calculating the cost of medical services using the Cobb – Douglas production function.Results. A unified classification of medical services based on their resource intensity and an improved method of forming the cost of medical services based on the Cobb – Douglas production function are proposed, revealing the dependence of the volume of production on two factors of production – capital and labor; the cost of medical services was calculated using the example of real services provided in one of the medical organizations of the public health sector of the Irkutsk region.Conclusions. The proposed method for determining the cost of a medical service based on its resource intensity makes it possible to determine the real cost of a medical service, the full reimbursement of which will increase the financial stability of medical organizations in the public sector, which will be reflected in the improvement of their material and technical base and, as a result, will increase the quality of medical services.

Optimization of Disassembly Strategies for Electric Vehicle Batteries

Various studies show that electrification, integrated into a circular economy, is crucial to reach sustainable mobility solutions. In this context, the circular use of electric vehicle batteries (EVBs) is particularly relevant because of the resource intensity during manufacturing. After reaching the end-of-life phase, EVBs can be subjected to various circular economy strategies, all of which require the previous disassembly. Today, disassembly is carried out manually and represents a bottleneck process. At the same time, extremely high return volumes have been forecast for the next few years, and manual disassembly is associated with safety risks. That is why automated disassembly is identified as being a key enabler of highly efficient circularity. However, several challenges need to be addressed to ensure secure, economic, and ecological disassembly processes. One of these is ensuring that optimal disassembly strategies are determined, considering the uncertainties during disassembly. This paper introduces our design for an adaptive disassembly planner with an integrated disassembly strategy optimizer. Furthermore, we present our optimization method for obtaining optimal disassembly strategies as a combination of three decisions: (1) the optimal disassembly sequence, (2) the optimal disassembly depth, and (3) the optimal circular economy strategy at the component level. Finally, we apply the proposed method to derive optimal disassembly strategies for one selected battery system for two condition scenarios. The results show that the optimization of disassembly strategies must also be used as a tool in the design phase of battery systems to boost the disassembly automation and thus contribute to achieving profitable circular economy solutions for EVBs.

Patient needs and resource intensity weighting in the ambulatory care unit

Across British Columbia Cancer (BC Cancer), oncology nurses work as part of an interdisciplinary team in the outpatient ambulatory care unit (ACU) and support patients across the trajectory of their cancer journey. Previous initiatives, which focused on identifying patient needs and nursing role optimization work, have enhanced role clarity, enabling nurses to articulate their scope of practice and specialty competencies required to best meet the needs of patients and families. However, while the patient needs and fundamental practice elements have been identified to optimize the ACU nursing role, a gap still exists in quantifying the staffing resources required to operationalize the current model of care. To address this gap, a quality improvement project was initiated to develop an internally validated ACU Nursing Resource Intensity Weighting (RIW) tool for projecting baseline staffing requirements. The tool can be utilized to inform strategic and operational planning discussions focused on improving the outpatient model of care in oncology.

Besoins des patients et pondération de la consommation des ressources dans l’unité de soins ambulatoires

Les infirmières en oncologie de British Columbia Cancer (BC Cancer) font partie d’une équipe interdisciplinaire dans l’unité de soins ambulatoires et accompagnent les patients tout au long de leur cancer. Des initiatives antérieures visant à identifier les besoins des patients et un travail d’optimisation du rôle des infirmières ont clarifié leur rôle, ce qui leur a permis d’exprimer clairement la portée de leur pratique et les compétences spécialisées nécessaires pour répondre au mieux aux besoins des patients et de leurs familles. Cependant, même si les besoins des patients et les éléments fondamentaux de la pratique ont été identifiés pour optimiser le rôle des infirmières en unités de soins ambulatoires, une lacune persiste dans la quantification des ressources en effectif nécessaires pour organiser le modèle actuel de soins. Pour pallier cette lacune, un projet d’amélioration de la qualité a été entrepris afin de développer un outil de pondération de la consommation des ressources (Resource Intensity Weighting, RIW) validé en interne pour les infirmières en unité de soins ambulatoires afin d’obtenir une projection des besoins de base en personnel. L’outil peut être utilisé pour alimenter les discussions de planification stratégique et opérationnelle qui visent à améliorer le modèle de soins ambulatoires en oncologie.

Determination of the necessary degree of national programs standardization by network and business planning methods

The article considers the application of methods that make it possible to determine the need for deeper standardization of processes within the framework of the implementation of national programs, based on the influence of the degree of standardization on the time and resource intensity of the implementation of national programs. To determine the impact of the degree of standardization on the implementation time of national programs implementation, it is proposed to use network-planning methods, taking into account the influence of the time required for the development and implementation of additional standards on the implementation of the national program. The impact of standardization on the resource intensity indicators of the implementation of national programs is proposed to be taken into account through the analysis of the dynamics of the amount of finance required for the implementation of the program. For this purpose, it is proposed to use business planning methods, namely: calculation of the costs associated with the development and implementation of additional standards and calculation of the financial benefits from deepening standardization, based on the calculation of the amount of reduction in the cost of financial resources per unit of the result of the national program implementation.
