Published: March 2023

Background: The elderly period is a gift in human life because not all humans can experience this period. The elderly period experience changes in anatomical and physiological functions, so the elderly are very vulnerable to health problems. Many factors cause health problems in the elderly, including decreased function of the elderly and elderly health problems that can affect the independence of the elderly in carrying out daily activities. This study aims to describe the health status and independence of the elderly in nursing homes and living with their families.

Method: This research is a descriptive analytic study with an elderly population. The number of respondents in this study were 19 elderly living in nursing home and 13 elderly living with their families. Data collection was carried out at one time, which are: measuring blood pressure, blood sugar levels, blood cholesterol, blood uric acid, and the independence of the elderly.

Result: The results showed that the health status of the elderly living in nursing homes was 19 people (100%) had normal blood sugar levels, 5 people (26%) had normal cholesterol levels, 8 people (42%) had normal uric acid levels, 9 people (47 %) had normal blood pressure, and independence shows that 10 people (53%) had the independence to carry out daily activities. The results of research at the elderly post for the data collection on the elderly living at home showed that 27 people (87%) had normal blood sugar levels, 16 people (52%) had normal cholesterol levels, 18 people (58%) had normal uric acid levels, 18 people (58%) had normal blood pressure, and independence showed that 31 people (100%) had the independence to do their daily activities. There are differences in the health status and independence of the elderly who live in nursing homes and those who live with their families.

Conclusion: The elderly who live with their family have better health and independence status than the elderly who live in nursing homes. For this reason, efforts are needed to improve the health status and independence of the elderly at nursing homes by holding regular health checks and practicing activities that can stimulate the independence of the elderly.

Introduction. Recently, the most desired goal in DC motor control is to achieve a good robustness and tracking dynamic of the set-point reference speed of the feedback control system. Problem. The used model should be as general as possible and consistently represent systems heterogeneous (which may contain electrical, mechanical, thermal, magnetic and so on). Goal. In this paper, the robust tilt-fractional order proportional integral derivative control is proposed. The objective is to optimize the controller parameters from solving the criterion integral time absolute error by particle swarm optimization. The control strategy is applied on DC motor to validate the efficiency of the proposed idea. Methods. The proposed control technique is applied on DC motor where its dynamic behavior is modeled by external disturbances and measurement noises. Novelty. The proposed control strategy, the synthesized robust tilt-fractional order proportional integral derivative speed controller is applied on the DC motor. Their performance and robustness are compared to those provided by a proportional integral derivative and fractional order proportional integral derivative controllers. Results. This comparison reveals superiority of the proposed robust tilt-fractional order proportional integral derivative speed controller over the remaining controllers in terms of robustness and tracking dynamic of the set-point reference speed with reduced control energy.
Modified discrete Fourier transform algorithm for protection of shunt compensated distribution line
Authors: Jani A. , Makwana V. H.
Published: March 2023

Introduction. The response time of the relay plays vital role when fault occurs on the line. Various algorithms are adopted to increase the sampling rate of the relay which, in turn, improves the response time. Methods. Discrete Fourier transform and modified discrete Fourier transform are the two algorithms used to calculate the fundamental frequency phasor of the signal required by the relay to initiate trip command. It is known that discrete Fourier transform takes four to five cycles to produce the fundamental frequency phasor but it fails to deal with the decaying DC component. On the other hand, modified discrete Fourier transform improves the response time by removing the decaying DC component along with the other harmonics in just one cycle and a few samples. The aim of this paper is to cover discrete Fourier transform and modified discrete Fourier transform algorithms to analyze the performance of the three overcurrent and one earth fault relaying scheme for different types of faults occurring in the distribution system. Methodology. The concept of three overcurrent and one earth fault scheme is also explained in this paper for protection of shunt-compensated distribution system. The scheme is designed for variable power factor. MATLAB/Simulink is used as the software tool to validate the results obtained for various types of faults occurring in the system. The results are represented graphically to illustrate the time of response of the protection scheme when shunt compensators are connected at the receiving end of distribution network.

Published: March 2023

The article deals with current issues of digital business transformations in the context of Industry 4.0, covering digitalization in all spheres of society, innovations in products and new business models. In particular, the platform has emerged as a new form of business that is built on providing a digital space for suppliers, consumers and other stakeholder groups. It was noted in the article that the main condition for creating a successful platform is the development of a mechanism for effective interaction. This ensures the quality and uptime of the platform. In addition, strategies for attracting users/consumers to the platform business were highlighted. It has been proven that if a company's income does not depend on the ownership or management of physical assets, there is no need for significant investments to scale. It was also noted that traditional businesses that have not transformed enough to create platforms may in the future face the fact that competition will arise in unrelated areas, since connections within the ecosystem play a key role in the ecosystem of platforms. As part of the study, it was also argued that in modern conditions the supply chain is no longer the main aggregator of business value, because a trend has been started to create and distribute it among platform participants, since a linear direction of movement to the end consumer is no longer assumed, the value moves immediately to the client and in the reverse direction, which leads to key differences in the operation of digital platforms. The key differences in the operation of digital platforms compared to linear business models were given.

Published: March 2023

The article proves that effective resource management of an industrial enterprise using intellectual resources is a key element of its development strategy, regardless of its size and market position. Enterprises for which intellectual property rights are a valuable asset should pay special attention to building a system of strategic management of them. This requires taking into account the issue of intellectual property protection in many management processes, the proper distribution of tasks and the creation of organizational structures, procedures, regulations and contracts, the determination of budgets and the provision of professional staff and tools. The analysis of existing publications made it possible to conclude that strategic development management is a scientifically based influence of top management on the socio-economic development of the enterprise, which ensures sustainable growth of the results of the commercial activity of the enterprise. It has been proven that the formation of a management system for the development of enterprises requires the presence of interconnected subsystems. A number of components of the industrial enterprise development management system based on intellectual property are proposed. It is recommended to determine the basic development strategy depending on the type of market behavior model of the enterprise, which largely depends on the level (estimation) of the external potential of the enterprise: high potential corresponds to an offensive model of enterprise behavior, low potential corresponds to a defensive market behavior model.

It was determined that the strategic tasks of intellectual property are: protection from competition: the presence of a patent provides the enterprise with a monopoly position in its target market for a sufficiently long period of time (up to 20 years); additional protection: some patents are not developed for the purpose of direct commercialization; avoidance of commercial (market) disputes: enterprises have the opportunity to commercialize their technologies for a long time without existing threats of abuse of their intellectual property rights by competitors; foundations for commercial alliances: finding business partners for a given business activity is much easier when the company has a competitive patent portfolio at its disposal.

Published: March 2023

The enterprise with a strong survival potential that can react quickly and adequately to changes in the external and internal environment can survive, which is only possible with a well-developed crisis planning system in the enterprise, in today's economic environment. The cries or the threat of crises are a constant phenomenon in the life of the enterprise. The root cause, i.e. the potential for crises, is the gap between the production and consumption of goods. The essence of economic crisis is manifested in the overproduction of goods relative to the solvent aggregate demand, in violation of the conditions of reproduction of social capital, in mass bankruptcies of firms, growth of unemployment and other socio-economic shocks. Formation of anti-crisis program belongs to the most responsible and weighty questions, because it is a reasonable choice of anti-crisis measures provides the output of the enterprise from the state of crisis with the least losses in the shortest possible time.Anti-crisis program is a system of measures aimed at preventing or eliminating unfavorable events for business by using the full potential of modern management, development and implementation at the enterprise of a special program, which has a strategic character The enterprise should use in full all five types of resources: material, human, financial, informational, time. They must be continuously monitored. The survival potential of the enterprise as an open system whose preconditions for the successful functioning must be sought not within the enterprise itself but outside of it.

Published: March 2023

The article examines and substantiates traditional and modern methodological approaches to the valuation of intellectual property objects of the enterprise based on the Monte Carlo method, the royalty rate method, the rules of the empirical approach, the hypothetical method of negotiations, the method of calculating the lost profit, the method of decision tree analysis. The economic essence and value of intellectual property objects for ensuring the efficiency of the economic activity of an industrial enterprise, taking into account many market and non-market factors influencing the evaluation result, were investigated. The composition and specifics of assessing the value of various types of intellectual property objects of an industrial enterprise in modern conditions have been worked out. Peculiarities of the use of the main methodical approaches to the assessment of the value of intangible assets, namely cost, profitable (revenue), market, are considered The field of use of the results of the conducted research is defined: the practical activity of domestic industrial enterprises, the professional activity of participants in the evaluation process, which is aimed at increasing the validity and reliability of the adoption and effectiveness of the practical implementation of strategic and the most important operational management decisions from the point of view of their impact on the value of existing intellectual assets and the market the cost of the enterprise in general.

It has been proven that intellectual property objects are an integral part of the most effective assets of an enterprise that carries out market-independent business activities. The process of determining the value of an intellectual property object is known as intellectual property valuation, and may vary depending on various factors, such as the type of intellectual property, its commercial value, the level of risk, the market nature and purpose of the intellectual property valuation, etc. Various traditional and modern methods are available for valuing intellectual property, but choosing the appropriate method is important to obtain its adequate value. The answer to the question "how to value an object of intellectual property" depends on the answers to other questions, such as "what to value", "when to value" and "for what purpose to conduct a valuation of an object of intellectual property".

Strategies for Prevention of Downhole Tool Failure Caused by High Bottomhole Temperature in Geothermal and HPHT Oil and Gas Wells
Authors: Khaled Mohamed Shafik , Wang Ningyu , Ashok Pradeepkumar , Chen Dongmei , van Oort Eric
Published: March 2023

High bottom hole temperature can lead to decreased downhole tool life in geothermal and high temperature / high pressure (HPHT) oil and gas wells. The temperature increase is exacerbated when circulation stops, e.g., during connection, tripping, well control situations, etc. While continuous circulation technology is an appropriate solution for managing temperature, it is not yet widely adopted in HPHT and geothermal drilling practices. This work investigates factors that impact downhole temperature and recommends strategies to better manage the temperature when continuous circulation is not available.

An integrated thermo-hydraulic model was developed to capture the transient behavior of downhole temperature and was applied here to study the transient temperature profile when there is no fluid circulation. The model was validated using the open-source FORGE field dataset, with the mean absolute percentage error (MAPE) between 1-4%. In addition, hundreds of case scenarios were numerically studied to investigate the impact of several key factors on the downhole temperature.

The evaluated factors include the pump-off time, type and physical properties of the drilling fluid, wellbore hydraulic diameter, reservoir temperature, geothermal gradient, total wellbore depth and profile, and operational parameters prior to stopping the circulation. The cooling effects of different drilling parameters were compared to a benchmark case of continuous circulation. A correlation map was generated to visualize the impact of those parameters on the downhole temperature distribution when circulation stops. A logarithmic relationship between the pump stop time and the downhole temperature was observed. For the FORGE case scenario, the downhole temperature increases by 27 °C and 48 °C after the pump stops for 30 and 60 minutes, respectively. It was observed that water-based mud with a high viscosity increases fluid convection heat resistance between the formation and wellbore. Also, drilling with a higher flow rate before stopping the pump can cool the near-wellbore formation faster and reduces the downhole temperature even after circulation ceases. Wells with high geothermal gradients, like FORGE wells, have higher temperature build-up during circulation stoppage than wells with low geothermal gradients targeting the same reservoir (formation) in-situ temperature.

This study investigates the efficacy of different cooling strategies to avoid downhole temperature build-up when there is no circulation. It thereby facilitates the optimization of geothermal and HPHT well design and construction to prevent downhole tool failures. The developed correlation map can aid drilling engineers understand the impact of different drilling conditions on the downhole temperature.
Novel Inflow Control Device Bridges the Gap Between Passive and Autonomous Technologies
Authors: Simonds Floyd , Zhao Liang , Montoya Jose
Published: March 2023

Operators in need of improved reservoir drainage, increases in ultimate recovery, and delay of unwanted fluid production are faced with a choice between passive and autonomous inflow control devices (ICD / AICD) to manage these issues most effectively. Production challenges leading to this choice are increasing as water production in particular across the globe continues to rise.

Passive Inflow Control Devices (ICD) have been used with great effect throughout the world. Multiple variants exist using nozzle, tube, or helical designs to balance inflow in long horizontal wells and those with permeability variations. Each type of ICD has various degrees of viscosity insensitivity, with the nozzle-type being seen as relatively viscosity insensitive, which is true when the viscosities of the oil and water are nearly similar. As the viscosities between the two diverge, however, all passive ICD's produce more water than oil at breakthrough for a given pressure.

As ICD's only delay the onset of water and gas breakthrough, however, the industry moved to develop Autonomous ICD's (AICD), which sense the presence of unwanted fluid without any connection to or intervention from the surface. The majority of AICD devices available currently contain moving parts and require close tolerances to deliver their unique benefits. They were initially specifically designed for light oil applications in long horizontal wells to shut off the majority of produced water overall. While this is desirable in low oil viscosity wells it may not be as effective with increases in viscosity due to the need to produce water in order to produce the oil.

The design proposed in this paper uses no moving parts, significantly restricts water production in a wide range of crude viscosities, is easily configured for a variety of downhole conditions, and delivers passive ICD performance with AICD benefits using a simple, reliable, and unique design.

The tool functions to restrict water production progressively as either oil viscosity or water cut increase without ever completely or nearly completely closing to production, which makes it an excellent solution for marginal production wells, younger reservoirs, and wells with lower overall production rates compared to other technologies.

The paper will discuss the theory of the device's functionality to differentiate between fluids present. Laboratory test results will be shown to demonstrate flow performance as well as API 19ICD[1] testing for erosion, plugging resistance, and mud flow initiation testing. In addition, an example comparing an open hole base case to the new device's performance in a sample reservoir will be discussed.
The First Application of a Cloud-Based Well Engineering Solution in the Middle East Region
Authors: Vij Jitesh , Garg Ankit , Kumar Bimal , Sedgwick Paul , Hussein Ahmad Naim
Published: March 2023

Low oil prices over the past few years have led oil and gas organizations to embrace digital transformation to improve the efficiency and quality of well design. Nowadays, digital transformation and reducing well construction can have significant impact on determining the financial viability of a discovery. Teamwork and the collaboration of numerous experts in different disciplines are required to achieve a properly engineered well design that can be executed with minimal risks.

Present-day well planning uses several increasingly obsolete techniques, including maintaining spreadsheets as risk registers, sharing multiple design iterations between disciplines, drilling, and geological concerns, manually replanning to accommodate changes, and people working in "silos"—often from different offices or from home. Along with this, planning software, when installed on a computer, may be difficult to maintain and update with new software releases. Often an expert in one discipline will not have visibility on the work done by other engineers, impeding collaboration. Many linear processes lead not only to increased well planning time but also to suboptimal well design resulting in higher planning and execution costs (Bello et al. 2014).

Today, the oil and gas industry lag in the adoption of digital technologies and most of the ones that exist are not used commercially. Often, the reason is that these solutions address only a very small part of the entire well construction workflow. They are not fully matured, have a poor user interface, and require heavy computing power. Operators, on the other hand, are looking for a full-suite solution and they do not have the resources or expertise to connect various digital solutions existing in the market from different vendors. The need of the hour is an integrated solution that is easy to adopt, provides a collaborative work environment, is cloud-based to leverage computing power (Tanaka et al. 2018), and most importantly supports all the major well design workflows.

In this paper, we discuss the first commercial application of a digital cloud-based well-planning solution in the Middle East region, which enabled Crescent Petroleum to become the first operator to adopt the system in UAE.

Successful fracturing operations heavily rely on the performance of fracturing fluids (FFs), which mainly include high sand-carrying capacity (SCC) and significant drag reduction (DR). Herein, a functional copolymer, SRP-6, was synthesized by introducing a zwitterionic surfactant, 4-((3-((3-(docos-10-enamido)propyl)dimethylammonio)-2-hydroxypropyl)amino)benzenesulfonate (SVBS), during polymerization, and its structure was characterized by Fourier transform infrared and 1H nuclear magnetic resonance (NMR). SRP-6 shows superior solubility, hydrodynamic volume, and microstructure in salinity water, thanks to the hydrophilicity of multiple functional groups in the copolymer structure, and the SVBS-induced pseudointerpenetrated network as well as the uniform distribution of multiple functional monomers. Furthermore, the SVBS, as a physical crosslinker, imparts the SRP-6/SVBS solution with outstanding rheological performance, SCC, and DR. In addition, the contribution of elasticity and viscosity to SCC was calculated. These results collectively suggest that the SRP-6/SVBS solution could be potentially used as a high-performance FF for the development of tight reservoirs.
Consensus Weighted Gene Co-expression Network Analysis demonstrates aberrations in folding of actin by CCT/TriC chaperonin family in Celiac disease

Published: March 2023

Background: Celiac disease (CeD) is an autoimmune enteropathy triggered by dietary gluten. Almost 90% of CeD patients have HLA-DQ2 or -DQ8 haplotypes. As a high proportion of first-degree relatives (FDRs) of CeD patients have the same haplotype, it is assumed that they are at a higher risk of disease development than the general population. Nevertheless, the prevalence of CeD among FDRs is considerably low (7.5%).
Methods: In order to figure out this discrepancy, a microarray dataset of intestinal mucosal biopsies from CeD, FDR, and control groups was reanalyzed, and gene co-expression network using WGCNA was constructed. The differentially expressed genes in the opposite modules from the consensus analysis were applied for functional enrichment analysis.
Results: WGCNA analysis identified 10 consensus modules in both CeD and FDR groups, including 5 modules with opposite correlation. Among the genes of opposing modules, 159 of them were identified as commonly differentially expressed genes with an adjusted p-value< 0.05 between FDR and CeD groups. Functional enrichment analysis revealed the significant contributions of these genes in host energy metabolism, programmed cell death, antigen cross presentation, and actin folding. In a deep view to the relation of actin folding to celiac disease occurrence, it was found that misfolding of actin and presentation of anti-actin antibodies occur in CeD patients. The current study reports that this pathway is oppositely regulated in FDR group and this might be a trigger for celiac manifestation.
Conclusions: The consensus signaling pathways with opposing expression patterns identified in this study give us a clue about the gene circuits that are dysregulated in celiac patients. Considering the prominent relation of actin folding to disease occurrence and its opposite manner in celiac patients and healthy individuals, it is proposed that targeting CCT/TriC chaperonin family might result in a reduction of misfolded actin and the production of autoantibodies.

Purpose: Communication with patients undergoing mechanical ventilation in the intensive care unit represents a challenge. The aims of the study were (1) to describe communication difficulties related to mechanical ventilation as experienced by caregivers and patients, and (2) to compare the use of a conventional low-tech communication board and a high-tech eye tracking technology-based device in order to improve communication effectiveness of mechanically ventilated patients in intensive care.
Methods: This prospective study consisted of a descriptive cross-sectional part describing the communication difficulties in the intensive care unit and an experimental randomized crossover part comparing the use of two technologically opposed augmentative and alternative communication interfaces. A mixed method approach was applied with a quantitative primary method and a qualitative complementary method.
Results: A total of 101 caregivers and 44 patients participated. Regarding the descriptive part, the communication difficulty analysis confirmed that mechanical ventilation constitutes a major problem in patient-caregiver communication. Regarding the quantitative experimental part, the treatment effects on transmitted messages quantity (2 median messages per exchange for the board versus 4 median messages per exchange for the eye tracking, p < 0.0001), success rate (80% for the board versus 100% for the eye tracking, p < 0.05) and patient satisfaction (68% negative satisfaction level for the board versus 100% positive satisfaction level for eye tracking, p < 0.0001) were significant. Regarding the qualitative experimental part, the communication content covered 8 themes for the board compared to 9 themes for the eye tracking and he use difficulties included 4 categories for the board as well as for the eye tracking.
Conclusion: The eye tracking device may improve communication effectiveness of mechanically ventilated patients compared to the conventional communication board, both quantitatively and qualitatively.

Background Limited real-world data exists on clinical outcomes in systemic lupus erythematosus (SLE) patients by SLE Disease Activity Index 2000 (SLEDAI-2K), hereafter, SLEDAI. We aimed to examine the association between SLEDAI score and clinical, patient-reported and economic outcomes in patients with SLE.
Methods Rheumatologists from the United States of America and Europe provided real-world demographic, clinical, and healthcare resource utilization (HCRU) data for SLE patients. Patients provided self-reported outcome data, capturing their general health status using the EuroQol 5-dimension 3-level questionnaire (EQ-5D-3L), health-related quality of life using the Functional Assessment of Chronic Illness Therapy (FACIT) and work productivity using the Work Productivity and Activity Impairment questionnaire (WPAI). Low disease activity was defined as SLEDAI score ≤4 and ≤7.5mg/day glucocorticoids; patients not meeting these criteria were considered to have “higher” active disease. Data were compared between patients with low and higher disease activity. Logistic regression estimated a propensity score for SLE based on demographic and clinical characteristics. Propensity score matched analyses compared HCRU, patient-reported outcomes, income loss and treatment satisfaction in patients with low disease activity versus higher active disease.
Results Data from 296 physicians reporting on 730 patients (46 low disease activity, 684 higher active disease), and from 377 patients’ self-reported questionnaires (24 low disease activity, 353 higher active disease) were analyzed. Flaring in the previous 12 months was 2.6‑fold more common among patients with higher versus low active disease. EQ 5D‑3L utility index was 0.79 and 0.88 and FACIT-Fatigue scores were 34.78 and 39.79 in low versus higher active disease patients, respectively, indicating better health and less fatigue, among patients with low versus higher active disease. Absenteeism, presenteeism, overall work impairment, and total activity impairment were 47.0-, 2.0-, 2.6- and 1.5-fold greater in patients with higher versus low disease activity. In the previous 12 months there were 28% more healthcare consultations and 3.4‑fold more patients hospitalized in patients with higher versus low disease activity.
Conclusion Compared to SLE patients with higher active disease, patients with low disease activity experienced better health status, lower HCRU, less fatigue, and lower work productivity impairment, with work absenteeism being substantially lower in these patients.
Generational Effect on Nurses’ Work Values, Engagement, and Satisfaction in an Acute Hospital
Authors: Tan Si Hui Evangeline , Chin Guey Fong
Published: March 2023

Background:
The present nursing workforce comprises four generational of nurses working side-by–side. While such generation blend adds invaluable diversity to the workforce, it also brings added complexity. The study aimed to describe and summarise work values and attitudes of four nursing generations, namely Baby boomers, Generation X, Y and Z.
Method:
A cross-sectional questionnaire study was adopted. A total of 778 nurses from an acute hospital in Singapore had completed the online questionnaire. The Work Value and Attitude scale measuring seven constructs (Work Centrality, Non-compliance, Technology Challenge, Work life balance, leadership, Power, and Recognition) was employed for data collection.
Results:
The Cronbach’s alpha was 0.714 for the overall instrument. Statistically significant differences amongst the four generations of nurses emerged in the Work Value and Attitude scale in the construct of non-compliance (p=0.007), technology challenge (p=0.027), work-life balance (p<0.001), and recognition (p<0.001). No statistically significant differences noted for the rest of the constructs.
Discussion and Conclusion:
The findings of this study highlights that differences in work values and attitudes exist amongst nurses of different generations. Generation-X are less likely to challenge the conventional norm and supervisors. Generation Y and Z are the most tech-savvy generations and can adapt quicker to new technology. There is also greater emphasis for work-life balance as the generation gets younger. Generation Y and Z nurses perceived that younger nurses do not get the due respect and recognition form their colleagues. Acknowledging the generational differences in work values and attitude can facilitate nursing management to tailor strategies to improve individual and organisation performance while creating a work environment that enhance intergeneration harmony and teamwork.
