A Unified Theory of All the Fields in Elementary Particle Physics Derived Solely from the Zero-Point Energy in Quantized Spacetime
Authors: Ishiguri Shinichi
Published: July 2019

We propose a new theory beyond the standard model of elementary-particle physics. Employing the concept of a quantized spacetime, our theory demonstrates that the zero-point energy of the vacuum alone is sufficient to create all the fields, including gravity, the static electromagnetic field, and the weak and strong interactions. No serious undetermined parameters are assumed. Furthermore, the relations between the forces at the quantum-mechanics level is made clear. Using these relations, we quantize Einstein’s gravitational equation and explain the Dark Energy in our universe. Beginning with the zero-point energy of the vacuum, and after quantizing Newtonian gravity, we combine the energies of a static electromagnetic field and gravity in a quantum spacetime. Applying these results to the Einstein gravity equation, we substitute the energy density derived from the zero-point energy in addition to redefining differentials in a quantized spacetime. We thus derive the quantized Einstein gravitational equation without assuming the existence of macroscopic masses. This also explains the existence of the Dark Energy in the universe. For the weak interaction, by considering plane-wave electron and the zero-point energy, we obtain a wavefunction that represents a β collapse. In this process, from a different point of view than Weinberg-Salam theory, we derive the masses of the W and Z bosons and the neutrino, and we calculate the radius of the neutron. For the strong interaction, we previously reported an analytical theory for calculating the mass of a proton by considering a specific linear attractive potential obtained from the zero-point energy, which agrees well with the measurements. In the present study, we calculate the strong interaction between two nucleons, i.e., the mass of the pi-meson. The resulting calculated quantities agree with the measurements, which verifies our proposed theory.

Background: After serious epidemics of chikungunya (CHIKV) and Zika (ZIKV) in the Americas, dengue (DENV) have reemerged in most countries. We analyzed the incidence, incidence rates, and evolution of DENV cases in Honduras from 2015-2018 and the ongoing 2019 epidemic. Methods: Using epidemiological weeks (EW) surveillance data on the DENV in Honduras, we estimated incidence rates (cases/100,000 population), and developed maps at national, departmental, and municipal levels. Results: From 1 January 2016 to 21 July 2019, a total of 109,557 cases of DENV were reported, 28,603 in 2019, for an incidence rate of 312.32 cases/100,000 pop this year; 0.13% laboratory-confirmed. The highest peak was reached on the EW 28°, 2019 (5,299 cases; 57.89 cases/100,000 pop). The department with the highest number of cases and incidence rate was Cortes (8,404 cases, 479.68 cases/100,000 pop in 2019). Discussion: The pattern and evolution of DENV epidemic in 2019 in Honduras has been similar to that which occurred for in 2015. As previously reported, this epidemic involved the north and central areas of the country predominantly, reaching municipality incidences there >1,000 cases/100,000 pop (1%). Studies using geographical information systems linked with clinical disease characteristics are necessary to attain accurate epidemiological data for public health systems. Such information is also useful for assessment of risk for travelers who visit specific areas in a destination country.

Published: July 2019

Three-dimensional (3D) printing has allowed for production of geometrically complex 3D objects with extreme flexibility, which is currently undergoing rapid expansions in terms of materials, functionalities, as well as areas of application. When attempting to print 3D microstructures in glass, femtosecond laser induced chemical etching (FLICE) – which is a subtractive 3D printing technique – has proved itself a powerful approach. Here, we demonstrate fabrication of macro-scale 3D glass objects of large heights up to ~3.8 cm with an identical lateral and longitudinal spatial resolution of ~20 μm. The remarkable accomplishment is achieved by revealing an unexplored regime in the interaction of ultrafast laser pulses with fused silica which results in aberration-free focusing of the laser pulses deeply inside fused silica.

Las infraestructuras de datos espaciales: un reto y una oportunidad en la docencia de la Geografía
Authors: Álvarez Otero Javier , Lázaro y Torres María Luisa de
Published: July 2019

La creciente importancia de los datos como materia prima exige al docente prestar una mayor atención a los mismos. Los servicios y visores de las Infraestructuras de Datos Espaciales (IDE), mantenidos por los organismos públicos responsables de ellos, ofrecen una gran riqueza de datos geográficamente referenciados o geodatos, lo que constituye un excelente recurso docente. Esos datos son libres, abiertos, ofrecen la ventaja de su calidad, interoperabilidad, transparencia, reutilización, facilidad de acceso y actualización, a veces en tiempo real, y con ellos, el estudiante puede alcanzar una comprensión del territorio más precisa. Se ha valorado la utilidad de su empleo a través de la técnica Delphi. Con ella, se ha reunido una gran riqueza de información aportada por expertos en IDE y usuarios (investigadores, técnicos y docentes), cuyo análisis ha permitido concluir que, a pesar del interés de los datos existentes en las IDE para la comprensión del territorio, existen barreras todavía que frenan su empleo, principalmente derivadas de su complejidad.
Make or Breakeven: Is Unconventional Oil Production Getting More Efficient?
Authors: Rassenfoss Stephen
Published: July 2019

The breakeven oil price is a rough, unregulated indicator for the jagged rhythm of the unconventional oil business.

Interest in the price at which finding or producing oil becomes profitable spiked after the oil price crash in 2014 put so much production below the profitable zone.

One sign of the times was that the Federal Reserve Bank of Dallas began asking oil and gas companies in and around Texas how high the oil price needed to be for them to make money drilling a well, starting in 2016.

“From our end, what we wanted is to get a feel for when a particular company will flip the switch and start drilling a new well or cut back on drilling activity,” said Mike Plante, senior research economist for the Dallas bank.

Once a year, the reserve bank asks operators to tell them what breakeven oil price is needed to justify continuing oil production from existing wells, and the price level needed to profitably drill a new well. Of the two, the drilling breakeven price has proved more useful for tracking the unconventional oil business, where constant drilling is required to maintain production.

There is a wide gap between the oil price needed to maintain production—which includes old wells in conventional fields—and the level needed to justify drilling horizontal wells with laterals that can stretch out 2 miles or more, nearly all of which are in unconventional plays.

Drilling breakeven is interesting to the bank because it is “looking for cutoffs where firms will be likely to dial up or dial down.”

When oil prices rose last year, oil and gas companies rushed to drill while profit margins were healthy. When prices fell late last year, drilling slowed. “What we are looking at now is modest growth and stabilization,” Plante said.

While these producers have benefitted from higher oil prices, productivity seems stagnant. The breakeven, which rises and falls based on production and cost changes, has shown little change in the median breakeven cost of production in the dominant US play, the•Permian.

Some big expenses have gotten cheaper. Proppant prices plunged with the advent of local sand mines. The number of days it takes to drill a well has dropped and 2-mile long laterals significantly lowered the number of wells•required.

But the breakeven cost “has been wiggling around $50. It has not changed much,” said Kunal Patel, associate economist at the Dallas Federal Reserve.

Since early 2017, the breakeven price per barrel is up $2 to $48/bbl in the Midland Basin of the Permian. To the west in the Delaware Basin, it rose $1 during that period to $49/bbl. When the survey began in 2016, it reported a $50/bbl average for the entire Permian.
Gamma-Ray-Tool Characterization Avoids Traditional Limitations
Authors: Carpenter Chris
Published: July 2019

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 191717, “Is API Enough for Gamma Ray Logs, or Do We Need More?” by Feyzi•Inanc, SPE, and Andreas Vogt, SPE, Baker Hughes, a GE Company, prepared for the 2018 SPE Annual Technical Conference and Exhibition, Dallas, 24–26 September. The paper has not been peer reviewed.

A major issue with gamma-ray (GR) logs is that the API definition is valid only if the tool is run in a 4.89-in. borehole filled with fresh water. Although all GR tools are intended to provide the same results for such a well, in the field there is no single one-size-fits-all concept. In this paper, the authors discuss the characterization process for GR tools and how they behave in boreholes different from the one used in the University of Houston (UH) GR characterization pit. Proposals for developing correction strategies so that GR logs become quantitative logs, rather than the qualitative logs of the past, also are outlined.

Introduction

One of the issues inherent in ensuring repeatability of GR logs starts with tool characterization. For decades, no common industry standard existed that defined the scale for measuring radioactivity. The chaos created by different tools providing radioactivity in different units in the same environments ended with the creation of the API unit in 1959. The definition of the unit was based on work done with the UH GR characterization pit. This specific pit has a 4.89-in. borehole and a casing to ensure stability within the surrounding synthetic formation.

One downside of the API definition is that different combinations of radioactive isotopes, environmental conditions, and tool designs may yield comparable count rates. UH GR pit characterizations of GR tools lose their validity as the wellbore diverges from this previously described specific borehole size and environment. Thus, environmental corrections are needed to bring readings to a reference borehole used for tool characterization.

Another issue with the UH GR-pit-based characterizations became evident with the emergence of logging-while-drilling (LWD) GR tools. The LWD tools were supposed to provide natural GR values comparable with those of wireline tools. Recommended practices for wireline tools did not have a provision for calibration of LWD GR tools that did not fit into the UH GR pit. Consequently, characterizations of LWD tools to provide results comparable with those of wireline tools became a topic of interest.

Background

Although the UH GR characterization pit still exists, it suffers from many issues. The facility is in a state of disrepair, with significant corrosion. In addition, its activity level is decreasing because of the presence of short-lived Ra-226 as one of the main ingredients in the high-activity zone. The radionuclide distribution is not even, causing gamma readings to change with the height, and rock dimensions do not correspond to those of an infinite rock environment.
Technology Focus: Subsea Systems
Authors: Hanssen Birger Velle
Published: July 2019

Technology Focus

Alternative solutions to traditional subsea production systems received more attention when the oil price was so low that only a few potential subsea field developments seemed to be profitable. During the past few years, more focus has been on how to use existing infrastructure to get more oil and gas from reservoirs than originally planned with its own platform or floating production, storage, and offloading vessel.

A subsea system with a long pipeline back to the nearest existing process plant with available capacity, in many cases, makes a field development economically attractive even at low oil prices.

However, some challenges need to be overcome by new technology when oil, water, and gas are to be transported in long subsea pipelines. In oil fields that are currently being considered, the length of these pipelines is typically 20 to 50 km, but tieback distances in gas fields today can be up to 220 km, as described in one of the papers presented at OTC this year (OTC 29232).

A major challenge in nearly all long subsea tiebacks is related to flow assurance. Hours, in some cases days, are required for the fluid to travel through a pipeline surrounded by cold water. The drop in temperature results in higher viscosity, wax deposition, and hydrate formation. The backpressure from friction losses and flow-regime effects also can restrict flow. Hence, innovative solutions are required to complement traditional subsea production systems that are based on natural flow to the surface.

Various system alternatives have been proposed and developed, but the use of subsea multiphase pumps at the seabed has so far been the most successful solution. However, the development of a pumping system that can be used at great water depths involves much more than just packaging of motors and pumps for subsea applications. The system needs electrical power to be transferred over long distances, and with this comes equipment such as subsea connectors, transformers, switch gears, and frequency converters.

The status of some of these technologies is described in this feature’s synopses.

Thread compounds play an important role in the sealing ability of casing connections in the oil and gas industry. Next to their lubricating role during assembly, most of these thread compounds make use of nonbiodegradable or persistent particle additives to aid in the sealing ability. Replacing these additives for biodegradable and nonpersistent alternatives is, however, a challenge in high–temperature (>150°C) well environments. This paper presents an investigation of the high–temperature failure mechanisms of thread compounds, with the aim of developing biodegradable high–temperature–resistant thread compounds. To this end, the performance of commercially available, environmentally acceptable thread compounds was investigated using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), high–temperature rheometry, and high–temperature pin–on–disk experiments. The compounds are assessed for their stability, consistency, lubricity, and the resulting wear at high temperature. The results indicated that, without exception, the commercially available thread compounds investigated in this study fail by adhesive and/or abrasive wear at approximately 150°C because of thermally induced degradation. To remedy this and to validate the found failure mechanisms, a prototype thread compound was developed. The conclusion was that a successful high–temperature–resistant environmentally acceptable thread compound can be developed using the methodology described. The key property of this thread compound is the ability to form a tribofilm during makeup that protects the surface at a later stage when the lubricant has lost its consistency and the base oil is fully evaporated.
Analysis and Review of Fluid-Particle-Size Predictive Models for Pipe Flow
Authors: Vasquez C.. , Pereyra E.. , Sambath K..
Published: July 2019

In this study we present a review of fluid–particle–size prediction models and a comprehensive database acquired from the open literature. The study is restricted to bubbles and droplets that are also called fluid particles. The data have been classified by flow regimes—namely, bubble, annular, liquid/liquid, and liquid/liquid through a restriction. Only studies in which the particle–size distribution is presented were considered. These distributions were used to calculate the experimental maximum, minimum, and Sauter mean diameters. A lack of experimental data for high–pressure and low–surface–tension systems has been identified. We use the database to evaluate the reviewed models and present the results. On the basis of the comparisons, we recommend models for particle–size predictions for the considered flow regimes.

Published: July 2019

Background

China has a substantial burden of chronic viral hepatitis. This study examines the evolution of approaches to navigate the barriers to access to direct-acting antiviral (DAA) based treatment for hepatitis C in Tianjin city, China.

Methods

Review of publically available literatures including published and grey literatures. On-site data extraction and key informant interview were conducted.

Results

Tianjin is the first area to pilot a capitated provider payment program for treatment of hepatitis C. Through which, the retirees, employees and residents spend 0.7, 1.0 and 5.6-6.8 months of their salary and disposable income for the treatment respectively. The Patient Assistance Program (PAP) eligible patients in financial hardship pay nothing for DAA, but have to pay insurance the expenditures of diagnosis and tests, and medications for adverse reactions with limited reimbursement. The PAP-eligible low-income patients who need treatment longer than 3 months have to co-pay with insurance the advance 3-month treatment before obtaining free DAA for continued treatment. By the end of March 2019, 876 hepatitis C patients registered the new insurance coverage and were treated in Tianjin, among which 153 were cured, 723 were under treatment and follow-up.

Conclusions

A government-led multi-party cooperation has enabled Tianjin to start unblocking the barriers. International experiences demonstrated that centralized bulk procurement is a good leverage for price negotiation, especially when innovative payment approaches are used to remove price as a barrier to access. To re-produce the above success, continued efforts are needed to develop stronger strategic price negotiation, preferably at the regional level or central level.
Hepatitis B, hepatitis C and HIV prevalence and related risk practices among key populations in South Africa: findings from a seven-city cross-sectional survey
Authors: Scheibe Andrew , Young Katherine , Versfeld Anna , Spearman C Wendy , Sonderup Mark , Sing Nishi Prabdial , Puren Adrian , Hausler Harry
Published: July 2019

Background: People who use drugs including people who inject drugs (PWUD/ID), sex workers (SWs) and men who have sex with men (MSM) are at increased risk for HIV and viral hepatitis infection. Limited data exists on the epidemiology of these infections among these key population groups (KPs) in South Africa. We aimed to describe the prevalence of hepatitis B (HBV), hepatitis C (HCV) and HIV and related risk factors among these KPs to inform effective responses.

Methods: We aimed to recruit 3 500 KPs across Cape Town (SWs, MSM, PWUD/ID), Durban (SWs, PWUD/ID), Pietermaritzburg (SWs), Mthatha (SWs), Port Elizabeth (SWs), Johannesburg (MSM) and Pretoria (MSM and PWUD/ID) for participation in a cross-sectional survey. We used an interviewer administered questionnaire to assess socio-demographic characteristics, drug use and sexual risk practices. We tested for HCV (antibody, viral load and genotype), HBV surface antigen (HBsAg) and HIV antibody. We used descriptive statistics to explore data, which was stratified by KP.

Results: Among the 3 439 included in the study (1 528 SWs, 746 MSM, 1 165 PWUD/ID) the median age was 29 years, most participants were black African (60%), and 24% reported homelessness. 82% reported substance use in the last month, including alcohol (46%) and heroin (33%). 75% were sexually active in the previous month, with condom use at last sex at 74%. HIV prevalence was 37% (highest among SWs at 47%), HBsAg prevalence 4% (similar across KPs) and HCV prevalence of 16% (highest among PWUD/ID at 46%).

Conclusions: HCV, HBV and HIV are major health threats for KPs in South Africa. While HIV is an important condition for all included KPs, HCV is of particular importance to PWUD/ID. For KPs, HBV vaccination and behaviour change interventions that support consistent condom and lubricant access and use are needed. Coverage of opioid substitution therapy and needle and syringe services and access to HCV treatment for PWUD/ID need to be expanded.
Piperacillin-tazobactam should be preferred to third-generation cephalosporins to treat wild-type inducible AmpC-producing Enterobacteriaceae in critically ill patients with hospital or ventilator-acquired pneumonia. A propensity score-matched analysis

Published: July 2019

BACKGROUND

The aim of this study was to compare the rate of therapeutic failure and emergence of resistance in critically ill patients treated by third-generation cephalosporins (3GCs) or piperacillin-tazobactam (PTZ) for wild-type AmpC-producing Enterobacteriaceae pulmonary infections.

METHODS

In a multicenter retrospective cohort study over a 4-year period, all patients treated for a pulmonary infection related to wild-type AmpC-producing Enterobacteriaceae who received documented antibiotic therapy with 3GCs or PTZ after less than 48 hours of empirical antibiotic therapy were eligible. The main outcome was the rate of therapeutic failure, defined by an impaired clinical response under treatment and/or a relapse of pulmonary infection related to the same pathogen. The secondary outcome was a secondary acquisition of derepressed cephalosporinase-producing Enterobacteriaceae.

RESULTS

Over the study period, 244 patients were included; 56 (23%) experienced therapeutic failure and 19 (8%) experienced secondary acquisition of resistance. In the non-adjusted cohort, the rate of therapeutic failure and emergence of resistance were significantly higher in the 3GCs group (32 vs. 18%, p = 0.011 and 13 vs. 5%, p = 0.035, respectively). In the propensity score-matched population, the 3GCs group was associated with higher rates of therapeutic failure (HR = 1.61 [1.27 – 2.07]). The secondary de-escalation to 3GCs after 48h of PTZ as a first-line antibiotic therapy was not associated with increased rate of emergence of resistance.

CONCLUSION

Our study confirms that third-generation cephalosporins should be avoided as first-line antibiotic therapy in wild-type AmpC-producing Enterobacteriaceae pulmonary infections.
Analysis of different levels of viral suppression in HIV-1 patients after antiviral treatment
Authors: DING LISHA , CHEN XI
Published: July 2019

Background

Though highly active antiretroviral therapy (HAART) has brought the tremendous benefits to the HIV patients, there are still some patients with low HIV replication after treatment. This study investigated the influencing factors of different levels of viral suppression in HIV-infected patients in Central China.

Methods

A total of 4424 HIV-infected patients treated in 2016 from Hunan Province were enrolled and divided into 5 groups according to the level of virus replication, characteristics and clinic indicators were analyzed.

Results

There were 3871 cases (87.5%) who maintained the viral loads under 200 copies/mL after treatment, 261 cases (5.9%) with repeated test results, 57 cases (1.3%) had sustained low-level replication of virus, and 235 cases (5.3%) had long-term high-level replication of virus. Not surprisingly, the trend of CD4 cell counts growth were correlated with the trend of viral loads declination. Age, transmission mode, CD4 cell counts baseline, the interval between test and treat and the final statues between 5 groups were significant differences (P <0.05). Compared with low-level replication group, patients with clinical phase I were more likely be in complete supression group than those with clinical phase IV; Patients transmitted by hetero sex were more likely to be with repeated viral loads than those transmitted by blood transfusion or contaminated blood products or mother-to-child. If we define viral loads always less than 200 copies/mL as the criterion for positive treatment, CD4 cell counts baseline under 500 n/µL and co-infected with HBV were independent risk factors for high HIV-1 replication, but young and test & treat were independent protective factors for viral suppression.

Conclusions

Early treatment is more effective in inhibiting viral replication, but screening for incomplete viral supression patients should be a routine practice in the management and control of HIV infection.

Authors: Prieto Joel Manuel
Published: July 2019

The purpose of this study is to meet the motivations and psychological state of the popular runners, differentiating between federated and non-federated, and between men and women. The sample was composed of 473 popular runners, using Motivations of Marathoners Scales (MOMS) and CSAI-2R to evaluate motivation and anxiety. The results indicate that federated runners present higher scores in sense of life and lower scores in self-confidence, achievement of personal goal, self-esteem and recognition search. On the other hand, the men obtained significantly higher scores on physical fitness, social interaction and attraction to the competition, convenience and competition and lower scores on the meaning of life.

Tools of the Trade: How Do You Perform and Interpret an Exercise Test?
Authors: Rischard Franz P. , Borlaug Barry A.
Published: July 2019

Background: Most pulmonary vascular disease (PVD) is poorly modifiable and incurable even with effective therapy. Therefore, adaptation to stress, the reserve of the cardiopulmonary system, is important for assessment of patient function and prognosis. Methods that assess the adaptation to stress, especially exercise, provide valuable insight into diagnosis, prognosis, and response to therapy.

Implications for Clinicians: We provide a comprehensive review of the indications, methodology, and interpretation, as well as practical information of the forms of provocative testing in PVD. We include 6-minute walk testing, noninvasive cardiopulmonary exercise testing (CPET), invasive CPET, and additional forms, including volume loading.

Conclusions: Through a clear understanding of the methodology in the assessment of PVD, the clinician can determine which of these “tools of the trade” are best suited to the individual patient and situation.

Published: July 2019

Modern organizations are increasingly becoming more complex whether it is sole proprietorships, partnerships or Limited Liability Companies (LLC) (and in many cases global) thereby engendering the need for complete, transparent, reliable and accurate information that can be accessed quickly by the assistance of different branches of global professional accountants such as Certified Professional Accountant, Chartered Accountant, Certified Public Accountant, Management Accountant, Cost Accountant, Financial Accountant, General Accountant, Auditor, Tax Accountant, CA, CPA, CMA, CIMA, CFA, CFO, ICPA and so on. Internationally most large business organizations are well organized by a broad and disparate set of shareholders. These shareholders require the information i.e. quantitative (financial) and qualitative (non-financial) relating to their various organizations in order to make ongoing decisions through financially like dividend or non-financially or strategic decisions â€“ which can range from deciding to invest more and hold more shares, sell off part or all of their holdings, take critical decision on the management and boards of the financial institutions and banks etc. Besides, other stakeholders need the information to make decisions relating to lending, taxation, employee benefits and remuneration. It is essential that the quality of decisions that investors can make is largely dependent on the reliable and quality of information available to them. However, one thing that is common to all organizations is that the accountant plays a pivotal role towards the successful achievement of their strategic objectives by ensuring that the critical ingredient required for decision making is prepared and presented in the required format.

Published: July 2019

Following the activities of a tyre recycling company in Johor, Malaysia, over 2000 people fell sick and 111 schools were shut when toxic substances were released into the Sungai Kim Kim, a river in Pasir Gudang. This paper examines the relevance of corporate environmental responsibility (CER) policy framework in ensuring constant environmental sustainability by corporate bodies in Malaysia. The paper adopts a comparative law research methodology to assess the potential impact of environmentally sustainable corporate social responsibility across two jurisdictions i.e., Malaysia and India. Looking at existing CER framework in another jurisdiction, the paper argues that voluntary and mandatory CER can strengthen existing environmental regulations in Malaysia under the environmental regulation in Malaysia.Keywords: Environment, Corporate Environment Responsibility, Malaysia, IndiaeISSN: 2398-4287 © 2019.

BACKGROUND

As the population of Taiwan continues to age rapidly, middle-aged and elderly people will increasingly begin to care for their older relatives. Therefore, the responsibility and complexity of care required from family caregivers will increase. The mobile health technology (mHealth) model has been successfully applied to numerous care services.

OBJECTIVE

To develop a mobile health app that supports family caregivers of various ages by meeting their home care needs, thus improving their quality of life, decreasing their severity of depression, and making them more empowered.

METHODS

This study applied a nonrandomized control-group pretest–posttest design. Purposive sampling was employed to recruit 30 family caregivers—16 middle-aged and 14 old family caregivers—from the home care cases of a regional hospital in Taipei. The developed home care mHealth app was used for management and monitoring of patient health. The outcomes measured were quality of life, level of depression, and sense of empowerment.

RESULTS

The results indicated that use of the mHealth app improved the technology acceptance, quality of life, depression level, and empowerment of the family caregivers. The old caregivers obtained quality of life scores that were 2.23 points higher, on average, than those obtained by the middle-aged caregivers P = .01, a significant difference. On the quality of life questionnaire, the old caregivers’ obtained scores for the health and family factors that were 2.75 P = .01 and 2.49 P = .01 points higher, respectively, than those obtained by the middle-aged caregivers, indicating significant differences. Regarding empowerment and depression, the scores obtained at different time points indicated that both groups became more empowered and less depressed over time, but no significant differences were discovered between the two groups.

CONCLUSIONS

According to our results, using the home care mHealth app had a positive influence the app is concluded to be a favorable tool for care education and management. Old caregivers found the software useful for managing patients’ physiological data, and they wished that other assistive methods were available to help them understand the internal functions. The software contributes to quality of life improvement, a decrease in depression severity, and empowerment enhancement and can be used by family caregivers as a reference for home care management in the future.
