Authors: BOCHAROVA N. , FEDOTOVA I.
Published: April 2023

The process of time management in the management of corporate projects is con­sidered. It was determined that time management is the process of deliberately structuring the work schedule of an employee and the enterprise as a whole to best meet the goals set before them. It is proposed to use corporate time management to increase the efficiency of its activities. The main principles of time management are considered, which are: goal orientation, work planning, priori­tization, orientation to opportunities, self-discipline, motivation, effectiveness and quality of rest, documenting goals, distribution of tasks, new activities and new knowledge, hierarchical planning, efficiency of work time distribution, converting creativity, information and communication. 20 most common time management methods used in corporations are analyzed: getting things done, perso­nal efficiency program, Gantt chart for planning tasks and time, do it tomorrow (Mark Forsterʼs method), T. Busenʼs mind map, D. Eisenhowerʼs priority matrix, ALPEN method, elimination me­thod, the "eat the frog" method (FrogBusiness), the "tomato" method, the "elephant" method or the "salami" method, fixed time methods (timing), the "Swiss cheese" method, the "6P" rule, the 50/5 principle, the Vilfredo Pareto (20/80), ABC analysis system, B. Franklinʼs time management system (pyramid), case sorting (M. Clarin method), 100 blocks. It is proposed to understand time manage­ment in project management as establishing the main goal, following it by developing the main stages of implementation, analyzing the availability of resources, setting priorities, developing an appropriate work schedule and monitoring each stage of implementation. Advantages and disad­vantages of each method are separated. It is proposed to understand time management in project management as establishing the main goal, following it by developing the main stages of implemen­tation, analyzing the availability of resources, setting priorities, developing an appropriate work schedule and monitoring each stage of implementation. It was determined that project management is a process of planning, organization, implementation and control over the project in order to achieve the set goal. It has been established that any project team can improve time management through a selection of tools. Choosing the right supplies, toolset, and time management techniques for your project team is critical to keeping everyone on schedule and meeting deadlines.

Published: April 2023

The scientific article implements a scientific investigation of the latest achieve­ments and developments of Ukrainian and foreign scientists and practitioners regarding the application of modern innovative business models, in particular the implementation of outsourcing, which enables the rationalization of management and production activities of enterprises and farms of all industries by transferring a certain part of their functions to enterprises partners, ensuring a reduction in overall costs and strengthening of their own competitive positions.
On the basis of generalizing the developments of scientists, highlighted in a number of recent sources, eight main areas of application of outsourcing are highlighted, in particular: IT technologies, accounting, marketing, logistics, personnel management, legal support, production and economic activity and production of components.
A careful analysis of scientific works devoted to evaluating the expediency of outsourcing in modern realities made it possible to identify certain problematic issues that require further processing and finding a solution: first, various scientists use a variety of different methods and approaches to evaluate the effectiveness of outsourcing services, which need to be streamlined; secondly, the selection of the most appropriate approach from this set necessitates the selection of key advantages and disadvantages of each of them.
The main purpose of the article is the analysis and systematization of methods and approaches to evaluating the effectiveness of the implementation of outsourcing services in various fields of application, as well as identifying their main advantages and disadvantages.
As a result of the study, based on a thorough analysis and generalization of the methods and ways of evaluating the effectiveness of outsourcing existing at the theoretical level and used in practice, five main scientific and methodological approaches were identified, and for each of them a description of the content was provided, key parameters were outlined, and positive and negative traits inherent in each of them were formulated. The fifth scientific-methodical approach is defined as the most expedient.
The mentioned developments are the basis for conducting further scientific investigations, in particular, the justification and selection of components-indicators of the integral indicator of  assessing outsourcing effectiveness.
Direct Shear Behavior of Fiber Reinforced Concrete Elements

Published: April 2023

Improving the accuracy of load-deformation behavior, failure mode, and ultimate load capacity for reinforced concrete members subjected to in-plane loadings such as corbels, wall to foundation connections and panels need shear strength behavior to be included. Shear design in reinforced concrete structures depends on crack width, crack slippage and roughness of the surface of cracks.

This paper illustrates results of an experimental investigation conducted to investigate the direct shear strength of fiber normal strength concrete (NSC) and reactive powder concrete (RPC). The tests were performed along a pre-selected shear plane in concrete members named push-off specimens. The effectiveness of concrete compressive strength, volume fraction of steel fiber, and shear reinforcement ratio on shear transfer capacity were considered in this study. Furthermore, failure modes, shear stress-slip behavior, and shear stress-crack width behavior were also presented in this study.

Tests’ results showed that volume fraction of steel fiber and compressive strength of concrete in NSC and RPC play a major role in improving the shear strength of concrete. As expectedly, due to dowel action, the shear reinforcement is the predominant factor in resisting the shear stress. The shear failure of NSC and RPC has the sudden mode of failure (brittle failure) with the approximately linear behavior of shear stress-slip relationship till failure. Using RPC instead of NSC with the same amount of steel fibers in constructing the push-off specimen result in high shear strength. In NSC, shear strength influenced by the three major factors; crack surface friction, aggregate interlock and steel fiber content if present. Whereas, RPC has only steel fiber and cracks surface friction influencing the shear strength. Due to cementitious nature of RPC in comparisons with NSC, the RPC specimen shows greater cracks width.

It is observed that the Mattock model gives very satisfactory predictions when applied to the present test results with a range of parametric variations; ranging from 0 % to 0.5 % in steel fibers content; from 0 % to 0.53 % in transverse reinforcement ratio; from 15 to 105 MPa in compressive strength of concrete. While it gives a poor prediction for a specimen with 1% steel fiber.

CHARACTERIZATION OF "WATER IN COAL TAR" EMULSIONS STABILIZED WITH PULVERIZED COAL MATTER © L.P. Bannikov, PhD in Technjcal Sciences (State Enterprise "Ukrainian State Scientific Research Institute of Coal Chemistry (UKHIN), 7 Vesnina str., Kharkiv, 61023, Ukraine) Difficulties in dehydrating coal tar, especially those with a high degree of pyrolysis, are associated with the complex nature of numerous intermolecular interactions that provide high viscosity of the dispersion medium. On the other hand, emulsions are stabilized by dispersed particles insoluble in toluene and quinoline. However, the most distinctive feature is the stabilization of water droplets by the particles of the coke oven carry–over. First of all, the carry–over is related to the chamber loading process as well as the steam and hydro injection used. This leads to the absorption of the smallest dust particles by the condensing tar. The presence of functional groups in the coal substance gives hydrophilicity to the generally hydrophobic conventional coal molecule. In addition, the mineral part of coal also contributes to the diffusivity of the substance, which makes it surface active and capable of stabilizing emulsions. It has been shown that such particles are capable of forming stable multiple emulsions, which, as is known from the experience of oil dehydration, are very stable. The formation of emulsions was carried out on a mechanical stirrer, samples of crushed coking coal were used as emulsifiers, clay and sand were taken as a hydrophilic standard, and industrial soot was used as a hydrophobic standard. The maximum volume of the emulsion was obtained when "Zh" coal and "OS" coal were used as a powder emulsifier. The minimum volume of the emulsion was formed when hydrophilic components, such as sand and clay, were introduced into the system. The formation of multiple emulsions of the "tar in water/water in tar" type was noted. With an increase in the degree of hydrophobicity of powdered emulsifiers, the droplet size decreases, the interfacial surface increases, and the emulsion becomes more stable. The emulsifying ability of powders is explained by the formation of a structural and mechanical barrier. Keywords: coal tar, quinoline-insoluble substances, coal substance, stabilizers, hydrophilicity, hydrophobicity, multiple emulsions.

Published: April 2023

White egg contains the most significant protein source that has been explored to give more benefit for health purposes.  This study evaluated the potential of antibacterial and antioxidant activity of white egg protein hydrolysate extracted from Indonesian avian eggs.  The avian egg materials used local Indonesian chicken eggs (kampung chicken), chicken breed eggs, duck eggs, and muscovy duck eggs.  The white egg was extracted by organic solvent and produced protein extracted which was dominated by ovalbumin and ovotransferrin.  The protein extracted was hydrolyzed by pepsin and then powdered using a freeze dryer.  Antibacterial and antioxidant activity was evaluated by agar well diffusion technique and 2,2-Diphenyl-1-picryl hydroxyl (DPPH) radical scavenging method.  All samples showed antimicrobial activity against Salmonella sp., Escherichia coli, Staphylococcus aureus, Bacillus cereus, and Bacillus subtilis with a concentration of protein hydrolysate at 40 mg/mL.  The antioxidant activity between avian species was different and dose-dependent.  Protein hydrolysate extracted from duck white egg exhibited the highest radical scavenging activity (65%) at 10 mg/mL concentration.  However, all white egg protein hydrolysate extracted from Indonesian avian eggs can potentially help reduce oxidation and microbial deterioration.

Published: April 2023

Chicken eggs are a staple food with a high enough animal protein content, but the price is quite affordable for all levels of society. This causes the consumption of chicken eggs to be relatively high compared to other animal protein sources, but currently, the amount of production and consumption by the public is not comparable; besides that, the price offered is constantly fluctuating. This study aims to determine price fluctuations and price movement patterns of broiler chicken eggs in Bengkulu Province. The data used is secondary data. The research method uses quantitative descriptive analysis. The research results show that. The risk of fluctuations in the price of broiler eggs in Bengkulu Province has a slightly higher risk for prices at the producer level when compared to prices at the consumer level. The development pattern of broiler egg prices in Bengkulu Province generally shows a positive direction. Fluctuations in the price of broiler eggs occur in specific periods. These fluctuations occur because they coincide with religious holidays such as Ramadan, Eid al-Fitr, Christmas and New Year, the influence of the Russia-Ukraine war, and economic problems due to the Covid-19 pandemic.

Authors: Sinaga Rusman
Published: April 2023

Solar Water Pumps (SWP) systems have been widely developed, especially in remote rural areas that cannot be reached by the electricity network of the State Electricity Company. The most common obstacle is that water supply through the SWP system is still relatively expensive, especially if solar panels are combined with the use of batteries. This study aims to assess the performance of the water pumping system supplied by monocrystalline and polycrystalline solar panels without using batteries. The method used in this research is the observation method by first designing and installing the SWP system using monocrystalline and polycrystalline solar panels. The results showed that in the use of monocrystalline and polycrystalline solar panels in the SWP system, the average efficiency of the solar panels was 6.87% and 6.73%, the average pump efficiency 33.85% and 32.34%, and the global efficiency 2.30%, and 2.17%.

Differential expression of TAGLN in cancer of the cervix.
Authors: Mamoor Shahan
Published: April 2023

Almost all cervical cancers are caused by infection with high-risk human papillomaviruses (HPVs) (1-3); the transcriptional features that distinguish the gene expression programs of HPV-induced cancers from that of cancers resulting from non-viral abrogation of tumor suppression remain incompletely defined. We mined published and public microarray datasets (4, 5) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the most common type of cervical cancer, cervical squamous cell carcinoma. We found significant differential expression of the gene encoding transgelin, TAGLN, when comparing tumor tissue from the human cervix to the tissue of origin. TAGLN mRNA was present at significantly lower quantities in tumors of the cervix as compared to normal tissues from the cervix. Analysis of human survival data revealed that expression of TAGLN in tumors of the cervix was correlated with overall survival in patients with cervical cancer. TAGLN expression changes may be important for the initiation or progression of cancer of the cervix in humans.

Design and Construction of a Low Cost of Solar Tracker Two Degree of Freedom (DOF) Based On Arduino
Authors: Sinaga Rusman
Published: April 2023

Recently, there has been an increase in the demand for solar panel installations. Unfortunately, it is mostly in a fixed surface or is in a stationary position. Hence, the power generated by the photo-voltaic (PV) cells decreases significantly according to different variations in solar radiation throughout the day. To increase the solar power generation, this paper proposes the design and construction of a two low-cost DOF solar tracker that follows the direction of the sun with a simple construction yet great precision. The system uses a closed- loop system where the light intensity is used as a reference for comparison by the Light Dependent Resistor (LDR) as an analog input to the Arduino and as a system controller. The tracking strategy uses the LDR orientation capability which can be divided into four directions, consisting of one direction, two directions, three directions and four directions of sunlight incident to the LDR sensor. The solar tracking system used is implemented in the Pseudo-Azimuths system which rotates from east to west and from north to south. In the experiment, the comparative evaluation between the 2 DOF solar tracking system and the static solar panel system is the main point of comparison in order to find out more reliable system. From the results of the tests, the results show that the proposed method increases the efficiency of the electrical energy of PV modules with an average value of 36.2% compared to a fixed model.

Subanesthetic doses of ketamine induce an antidepressant effect within hours in individuals with treatment-resistant depression while it furthermore induces immediate but transient psychotomimetic effects. Among these psychotomimetic effects, an altered sense of self has specifically been associated with the antidepressant response to ketamine as well as psychedelics. However, there is plenty of variation in the extent of the drug-induced altered sense of self experience that might be explained by differences in basal morphological characteristics, such as cortical thickness. Regions that have been previously associated with a psychedelics-induced sense of self and with ketamine’s mechanism of action, are the posterior cingulate cortex (PCC) and the pregenual anterior cingulate cortex (pgACC).In this randomized, placebo-controlled, double-blind cross-over magnetic resonance imaging study, thirty-five healthy male participants (mean age±standard deviation (SD)=25.1±4.2 years) were scanned at 7 T. We investigated whether the cortical thickness of two DMN regions, the PCC and the pgACC, are associated with disembodiment and experience of unity scores, which were used to index the ketamine-induced altered sense of self. We observed a negative correlation between the PCC cortical thickness and the disembodiment scores. In contrast, no significant association was found between the pgACC cortical thickness and the ketamine-induced altered sense of self. In the context of the existing literature, our findings highlight the importance of the PCC as a structure involved in the mechanism of ketamine-induced altered sense of self that seems to be shared with different antidepressant agents with psychotomimetic effects operating on different classes of transmitter systems.

Published: April 2023

Digital Technology growth has unprecedentedly impacted daily life, providing opportunities and engendering challenges for professional social work practice. Social media, as an interactive technology, allows people to communicate and exchange ideas in the forms of images and videos with others not in their immediate vicinity. The present study aims to study the relationship between social media addiction and healthy lifestyle practices among postgraduate students from a social work perspective. The descriptive research design was used for this cross-sectional study conducted among 111 postgraduate students of Pondicherry University. The questionnaire includes a socio-demographic profile, a social media addiction scale, and a healthy lifestyle screening tool. According to the findings, most (66.7 per cent) respondents have a medium addiction to social media. Most (64.9 per cent) respondents follow a healthy lifestyle to a moderate extent. A significant association exists between social media addiction and a healthy lifestyle. The students are highly vulnerable, at the threshold of high addiction levels, and their lifestyle might become susceptible and precarious. Social workers may play a pivotal role in using Information, Education, and Communication (IEC) to bring behavioural change among the youth.

This paper discusses a problem whether the war in Ukraine is so specific that it was necessary to adopt the Act of 12 March 2022 on assistance to Ukrainian citizens in connection with the armed conflict in the territory of that country, instead of providing assistance under the Act on granting protection to foreigners of 13 June 2003. Based on a preliminary examination of Polish law, the Geneva Convention Relating to the Status of Refugees of 1951, Directive 2001/55/EC on minimum standards for giving temporary protection in the event of a mass influx of displaced persons, the Council Implementing Decision (EU) 2022/382 establishing the existence of a mass influx of displaced persons from Ukraine, and scholars’ opinions, the author has established that the Polish legislator rightly extended the subjective scope of the law applicable to persons granted temporary protection, and the respective Polish regulations are consistent with the letter and the spirit of international law. De lege ferenda conclusions are also propounded.

The objective of the paper is to prove the validity of the claim that a minor can be an entrepreneur. Minors involved in a business activity may perform legal acts or make transactions through a statutory representative and, in some situations, with the consent of a guardianship court. The requirement of full legal capacity is not included in the definitions of an entrepreneur provided in normative acts. Only special laws, in explicitly specified cases, make the economic activity contingent on having full legal capacity.

La investigación sobre la movilidad humana en la región centro-norte del occidente de México tuvo un proceso que se puede describir en cuatro etapas en orden cronológico: se inicio con la integración de un equipo de trabajo en donde participaron organizaciones de la sociedad civil, académicos y estudiantes. De ahí se vio la necesidad de construir un lenguaje común, lo que dio ocasión para construir de manera participativa un referente teórico conceptual, partiendo de una propuesta previa. Y, con base en este nuevo marco teórico se diseñaron instrumentos de recopilación de datos en la lógica de la encuesta etnográfica (etnoencuesta), la entrevista semiestructurada y la investigación aplicada y multisituada. De ahí que el trabajo de campo se desarrollara en espacios que abarcaron los estados de Guanajuato, Jalisco, Nayarit, Sonora y Baja California, quedando pendiente Sinaloa.

Desde uma tenra idade, as mídias audiovisuais se fazem presentes e influenciam a vida dos indivíduos. Nos últimos anos, especialmente os filmes têm sido utilizados como ferramenta pedagógica para a discussão ou contextualização de conteúdos. Essa utilização pode despertar a atenção dos alunos ainda mais do que métodos tradicionais. A fim de trazer uma contribuição ao ensino de Ciências, descrevemos nesse trabalho o desenvolvimento e a aplicação de uma metodologia utilizando um filme de ficção científica intitulado “Viagem Fantástica” (1966), com uma classe de estudantes do 8º ano do Ensino Fundamental. Utilizamos a estratégia “pausa dialogada”, na qual, em momentos específicos do filme, uma pausa é realizada para que os alunos discutam em pequenos grupos questionamentos apresentados pelo professor. A troca de opiniões e informações entre os pares, seguida após o filme por uma discussão geral do docente com a turma sobre as questões, auxiliou na revisão de conteúdos ligados ao corpo humano e estudados ao longo do ano letivo. Atividades adicionais envolvendo leituras, confecção de painéis e produção de redações complementaram a metodologia. Através das falas dos próprios alunos, percebeu-se que houve um despertamento da curiosidade e da motivação, além de uma melhor compreensão dos temas trabalhados.

Chatbots have experienced significant growth over the past decade, with a proliferation of new applications across various domains. Previous studies also demonstrate the trend of new technologies, especially artificial intelligence, being adopted in libraries. The purpose of this study is to determine the current research priorities and findings in the field of chatbots in libraries. A systematic literature review was performed utilising the PRISMA checklist and the databases Scopus and Web of Science, identifying 5734 records. Upon conducting the first screening, abstract screening, full-text assessment, and quality assessments guided by the CASP appraisal checklist, 19 papers were deemed suitable for inclusion in the review. The results of the review indicate that the majority of the existing studies were empirical in nature (primarily adopting qualitative methods) and technology reviews with a focus on reviewing the implementation and maintenance, design, evaluation, characteristics, and application of chatbots. The chatbots of interest were mainly text-based and guided chatbots, with closed-source tools with access portals mostly built on library web pages or integrated with social software. The research findings primarily concerned the development models and necessary tools and technologies, the application of chatbots in libraries. Our systematic review also suggests that studies on chatbots in libraries are still in the early stages.

Published: April 2023

Background: Access to specialists facilitates appropriate Alzheimer’s disease and related dementia (ADRD) medication use and adherence. However, there is little information on the impact of specialists’ availability on ADRD medication adherence, especially in regions of the United States (US) where specialists are scarce, e.g., the Deep South (DS). Objective: To ascertain whether the availability of specialty physicians in the DS and other US regions predicts ADRD medication adherence among community-dwelling older adults Methods: We conducted secondary analyses of claims data for 54,194 Medicare beneficiaries with ADRD in 2013–2015. Medication adherence was measured using the proportion of days covered (PDC). Multivariable-adjusted Modified Poisson regression was used to examine associations of adherence with physicians’ availability by region. Results: The race/ethnicity distribution was 81.44% white, 9.17% black, 6.24% Hispanic, 2.25% Asian, and 1% other; 71.81% were female, and 42.36% were older than 85 years. Beneficiaries across regions differed in all individual and contextual characteristics except sex and comorbidities. Neurologists and psychiatrists’ availability was not significantly associated with adherence (DS = 1.00, 0.97–1.03 & non-DS = 1.01, 1.00–1.01). Race and having ≥1 specialist visits were associated with a lower risk of adherence in both regions (p < 0.0001). Advanced age, dual Medicare/Medicaid eligibility, and living in non-large metropolitan areas, were associated with adherence in the non-DS region. Conclusion: Among older Americans with ADRD, a context defined by specialist availability does not affect adherence, but other context characteristics related to socioeconomic status may. Research should further examine the influence of individual and contextual factors on ADRD treatment among older adults.

Published: April 2023

CCHPs (Combined Cooling, Heating, and Power Systems) are capable of providing cold energy, heat, and electricity to users, allowing cascading utilization of energy and improving energy efficiency. The imbalance between cooling, heating, and electrical energy makes it difficult to accurately evaluate the performance of a CCHP system. Existing indices for evaluating the performance of the CCHP system do not account for the influence of time-sharing tariffs; therefore, the quantitative index of time-sharing is added and the time-sharing economic exergy efficiency of the radiator is established. Given that the electrical and thermal characteristics of the advanced absolutely hot compressed airheat storage system (AA-CAES) can complement the CCHP system, a model of the CCHP system with AA-CAES is established, which can be used to validate the validity of the quantitative evaluation index of time-sharing. A planetary search algorithm is proposed for solving the CCHP system model to address the multi-parameter solving characteristics of the CCHP system model and the disadvantages of the existing multi-objective optimization algorithms, which are prone to local optimality and poor optimization accuracy. Simulation validation demonstrates that the time-sharing economic exergy efficiency proposed in this paper can more accurately reflect the total energy consumption of the CCHP system than the existing evaluation indices. The performance of the CCHP system can be improved by using AA-CAES as a heat storage device.

Intonation evaluation is an important precondition that offers guidance to music practices. This paper present a new intonation quality evaluation method based on self-supervised learning to solve the fuzzy evaluation problem at the critical intonations. Firstly, the effective features of audios are automatically extracted by a self-supervised learning-based deep neural network. Secondly, the intonation evaluation of the single tones and pitch intervals are carried out by combining with the key local features of the audios. Finally, the intonation evaluation method characterized by physical calculations, which simulates and enhances the manual assessment. Experimental results show that the proposed method achieved the accuracy of 93.38% which is the average value of multiple experimental results obtained by randomly assigning audio data, which is much higher than that of the frequency-based intonation evaluation method(37.5%). In addition, this method has been applied in music teaching for the first time and delivers visual evaluation results.
Clinical Trial Highlights – Interventions Promoting Physical Activity in Parkinson’s Disease

Despite increasing evidence on exercise in Parkinson’s disease (PD) it remains unclear what type and intensity of exercise are most effective. Currently, most evidence favors moderate- to high-intensity aerobic exercise for its positive effects on motor symptoms as well as disease modifying potential. On the other hand, observational studies have shown that the sheer volume of exercise matters as well, independent of intensity. So far, the efficacy of the volume of exercise has not been confirmed by randomized controlled trials (RCTs). Here, we provide an overview of the ongoing RCTs that promote physical activity in daily life in PD. We found seven RCTs with sample sizes between 30 and 452 and a follow-up between 4 weeks and 12 months. Steps per day is the most commonly reported primary outcome measure. The ongoing RCTs will provide evidence for feasibility, whereafter the PD research field is ready for a next step and to explore the effect of physical activity on disease progression and PD symptoms.
School experiences following traumatic brain injury: A longitudinal qualitative study
Authors: McCart Melissa , Todis Bonnie , Gomez Douglas , Glang Ann
Published: April 2023

BACKGROUND: This longitudinal qualitative study tracked students with traumatic brain injury (TBI) from hospital discharge through their return to school and then for an average of four years of school. OBJECTIVE: To better understand the experiences of students and parents in the education system following TBI. METHODS: Participants were parents and educators of 21 students with TBI. Interviews were conducted using open-ended questions and students were observed in the classroom. RESULTS: From these data, three themes were identified: lack of student tracking year to year, lack of educator training, and conflicting views between educators and parents about students’ needs. These factors ultimately led to parent frustration and eventually conflict and deteriorating relationships between parents and educators. CONCLUSION: The results suggest that improving educator training could positively affect the factors identified and possibly mitigate parent frustration.

BACKGROUND: Over the last 50 years arthroplasty became the gold-standard treatment for disabling conditions of the coxofemoral joint. Variations of anterior, lateral, and dorsal incision have been applied, but as each approach requires the incision and reflection of various muscles to gain adequate exposure of the joint results are still controversial. OBJECTIVE: The purpose of this study was to develop a minimal-invasive, tissue-sparing approach in sheep with reduced risks in animal testing. METHODS: 12 mature sheep underwent hip surgery as part of a study to evaluate a hip resurfacing system. In line with the preliminary cadaveric tests a modified, minimal-invasive, musclepreserving surgical approach was sought after. RESULTS: We developed a surgical approach to the coxofemoral joint in sheep using only blunt tissue dissection after skin incision without any limitations in joint exposure or increased blood loss/duration of surgery. CONCLUSION: Even though limitations occur and femoral orientation in sheep differs from man, joint forces have similar relative directions to the bone with similar bony and vascular anatomy. Therefore, this minimal-invasive muscle preserving approach might be a safe and comparable alternative in still inevitable animal testing.

BACKGROUND: A variety of reviews have indicated the effectiveness of smartphone-based interventions in preventing secondary cardiovascular disease (CVD). However, few studies have focused on clinical outcomes. OBJECTIVE: This meta-analysis aimed to evaluate the potential benefits of application interventions and short message service (SMS) interventions on CVD outcomes. METHODS: Electronic databases were searched to identify randomized controlled trials (RCT) investigating an application or SMS intervention for secondary CVD prevention. Primary outcomes included major adverse cardiovascular events (MACE), cardiovascular death, and cardiac hospitalization. Secondary outcomes were cardiovascular risk factors (BMI, blood pressure, and cholesterol). RESULTS: A total of 26 RCTs were included, with 16 investigating applications and 10 assessing SMS. Overall, there was no significant difference in MACE, cardiovascular death, and cardiac hospitalization when comparing application interventions with usual care, as well as comparing SMS with usual care. Subgroup analysis revealed that patients who received applications without a medical interface had a significantly lower incidence of MACE (OR = 0.56; 95% CI: 0.33, 0.98). Participants who received applications with a medical interface showed a tendency towards higher rates of cardiac hospitalization (OR = 2.03; 95% CI: 0.85, 4.87). Significant reduction in waist circumference (SMD =-0.80; 95% CI: -1.58, -0.03) was found in application interventions compared to usual care; while significant reductions in SBP (SMD =-0.08; 95% CI: -0.15, -0.01) and TC (SMD =-0.31; 95% CI: -0.57, -0.08) were found in SMS interventions compared to usual care. CONCLUSION: Smartphone-based interventions, including applications and SMS, have the potential to benefit the secondary prevention of CVD. Applications may reduce the incidence of cardiovascular-related adverse events, while SMS interventions may improve cardiovascular risk factors.
