Authors: Erma Darmono , Supriyadi Supriyadi , Santoso Umar
Published: September 2022

This research was aimed to investigate the potential of young coconut (Cocos nucifera L.) leaf extract as an antioxidant and antibacterial active compounds. In this study, the physical, mechanical, antioxidant, and antibacterial activity of chitosan-based film with addition of young coconut leaf extract were examined. The young coconut leaf extract was prepared by maceration using ethanol for 48 hours at room temperature. The antioxidant and antibacterial activities were determined by the DPPH and well diffusion methods, respectively. The total phenolic and flavonoids were analyzed using spectrophotometric method. The film was prepared using 1.0 and 1.5% chitosan solution added with young coconut leaf extract at 0, 0.1, and 0.3%. The characterization of the film included color, tensile strength, elongation, WVP, film morphology, identification of functional groups, and total phenolic and antioxidant activity release. The results showed that the antioxidant activity of young coconut leaf extract was IC50 of 58.61 ppm. The antibacterial activity test showed that the inhibitory zone for S. aureus, Salmonella sp., and E. coli were 17,66, 24.40, and 12.27 mm, respectively. Total phenolic and flavonoid contents were 129.27 mg GAE/g extracts and 3.92 mg QE/g extract, respectively. The color of the film was dark. The higher the concentration of chitosan and the young coconut leaf extract, the higher the tensile strength, whereas the value of elongation at break and water vapor permeability decreased. The release of total phenolic was higher in lipophilic food simulants than in an aqueous system. The result of the study reveals that chitosan-based film added with young coconut leaf extract had great potential as an active biodegradable film for food packaging systems.

Published: September 2022

The World Health Organization recommends the use of respiratory protective equipment, in this context masks, as a way to alleviate the severe acute respiratory infection disease pandemic COVID19 (SARS-CoV-2). This recommendation was made to the general population, not just health professionals or people who are in direct contact with the sick. Generally speaking, there was a lot of publicity for the use of masks, but there was no disclosure of what would be the most important requirements to be considered for the choice. In this context, the objective of this work was to verify the understanding of the community in general about what are the important requirements in choosing a protective mask against pathogens. For this, an analysis was carried out in 200 scientific articles where it was possible to obtain five keywords related to the most important requirements when choosing a mask, namely: comfort, safety, cost, reuse and facial adjustment. An opinion poll was carried out in 4 groups, in which a weighting was requested for each keyword. The first group is composed of five health professionals and five teachers, the second of five students and people randomly chosen from the community. The objective is to study the influential criteria for the choice of respiratory protection equipment using the mathematical method Decision Making Trial and Evaluation Laboratory (DEMATEL) to demonstrate the influence relationship between the criteria. As a result, it was found that the group of professionals considers criteria related to safety and the group of non-professionals considers factors related to cost and reuse, and this demonstrates a higher risk of infection.
Automata Theory in the WEFW nexus: Experience from the cities in the Global South
Authors: Tonui Kibet
Published: September 2022

The major societal interests among the urban community at the moment represent a wide array of sustainable energy, climatic regulation, proper water use and sustainable production and consumption of renewable resources. As people migrate to urban areas, and more than half of the world population now live in cities, more pressure is put on the Water-Energy-Food-Waste (WEFW) systems. Devoid of plans for sustainable provision of WEFW services, cities may suffer water stress, starvation, load shedding and choked with waste. In this regard, among the dilemmas faced by urban managers is which methodologies would appropriately fix these problems and why. They can either (i) treat each of these problems individually or (ii) address them as one complex problem. This paper adopts the Automata Theory (AT) to explain how these options are affected by the nature of WEFW nexus, in what way the effects are transferred in the states and the opportunities and cautions from this nexus that affect the management of urban dynamics. A total of 16 articles analysing WEFW nexus and 20 articles covering interactions between WEFW elements were reviewed. Results show that the management of the interconnections between the WEFW elements contributes to either the realization or the breakdown of the urban systems. Empirical studies to establish resultant interactions between nexus sub-systems and developing integrated planning tools for inclusive policy processes that consider the vast array of this nexus in the current complex systems is fundamental.
‘The God of Small Things’: A Narrative of Catastrophic Misogynistic Approach
Authors: Darkhasha Dr.
Published: September 2022

Arundhati Roy is one of the most noted Indian novelist, essayist and activist who mainly stresses on issues related to social justice and economic inequalities. She is the writer who has created ripples round the globe by her gripping write-ups. She has been rightly awarded and bestowed with honour for her daring effort. She stands as the most controversial author amongst the clutch of contemporary Indo-Anglian writers. My simple reason for choosing her work is that I vehemently feel the contemporary critics have failed in bringing forth her true identity as a sensitive writer. She is not a traitor but a ‘world denizen with humane concern’. Her novel ‘The God of Small Things’ has harboured huge worldwide literary attention for its unique writing style and sensational story line. It is acknowledged as a complex and diverse piece of writing that incorporates varied themes such as marriage, divorce, abuse, death, alienation, gender issue, class division and political and religious conflict. The present paper deals with the kaleidoscopic inter play of relationships in the male chauvinistic society, highlighting the dominant role of elderly women whose guidance and stringent norms ruin the life of the younger female generation. The story takes the readers in its stride and enwraps them in its roller coaster ride until breathless.

Published: September 2022

Both cattle and buffalo are rich genetic resource, raised for dairy, meat and draft purposes and possess great economic significance globally. Genomic characterization is imperative to explore inherent potential of animal species for targeted improvement in performance traits. This study aimed to perform comparative genomic characterization and sequence analysis of casein genes family (CSN1S1, CSN1S2, CSN2 and CSN3) in Bos taurus and Bubalus bubalis. Phylogenetic, motif, conserved domain and gene structure analyses discovered evolutionarily conserved nature of these genes in cattle and buffalo. Results indicated that casein proteins were thermostable and hydrophilic, although αs1, β, and κ caseins showed acidic behavior except for αs2-casein that was somewhat basic. The present study revealed lower distribution of transcription binding (TFB) sites particularly CAP, GATA, HSF2 and LMO2COM in Bubalus bubalis as compared to Bos taurus which might have potential effects on the transcription and translational efficiencies of casein genes in Bos taurus. However, functional studies are required to evaluate the effects of these TFB sites on regulation of casein genes expression in Bos taurus and Bubalus bubalis.

Every year World Thyroid Day is observed on May 25 to spread awareness on the disorders of thyroid gland and their prevention. Yet the increase in thyroid problems is unabated. In fact, thyroid is one of the most important endocrine glands that regulates all most all body functions of human beings. It synthesizes and secrets 2 main hormones, thyroxine(T4) and tri-iodothyronine(T3), both being regulated by thyroid-stimulating hormone (TSH). While the whole amount of circulating T4 is produced by the thyroid gland itself, T3 is mostly generated in liver and kidney by peripheral mono-deiodination of T4 with the help of an enzyme, 5'-deiodinase (5' D). Thyroid hormones are vital for the well-being of a person and their abnormal levels lead to health problems. People with thyroid abnormalities suffer either from hypo-functioning (hypothyroidism) or from hyper-functioning (hyperthyroidism) of the gland. However, most common thyroid problem is hypothyroidism and females suffer more from this as compared to males. According to Chiovato et al. (2019), hypothyroidism affects about 5% of the general population and 5% more are believed to be sufferers, but undiagnosed. Primary hypothyroidism is normally diagnosed with low serum thyroid hormones and high TSH concentrations than the normal reference ranges. Symptoms of hypothyroidism include intolerance to cold, mild to moderate weight gain, dry skin, puffiness of the body, peri-orbital swelling, chronic fatigue, constipation, depression, hoarse voice and menstrual irregularities.The consequences of untreated or under-treated hypothyroidism include cretinism, myxoedema and goitre, even coronary artery disease.

Aim: This study aimed at the species identification of selected indigenous earthworms of Manipur and Assam, Northeast India along with an exotic species using morpho-anatomical study and DNA barcoding. Methodology: Indigenous species of earthworms were collected from Imphal and Jorhat, North-eastern part of India. The exotic species of earthworm were collected from Indian Council of Agricultural Research Complex, Manipur. The samples were collected by digging and hand sorting method. Identification of samples was done by both conventional and molecular methods. Molecular characterization was accomplished through PCR amplification of the mitochondrial cytochrome oxidase I (COI) genes. Automatic sequencing reactions were performed for the amplified PCR products on ABI3100 Genetic Analyser (Applied Biosystems). Results: Out of five specimens (EM1, EM2, EM4, EG5 and EM6) examined through morpho-anatomical studies, three were identified to species level while the other two were identified to their genus level only. Out of EM1 and EM2 specimens in the genus Perionyx as per the morpho-anatomical studies, DNA barcoding could deduce the EM2 specimen up to the species level as P. excavatus. The exotic EM6 specimen morphologically identified as Eisenia fetida showed 99% COI gene sequence similarity with both E. fetida and E. andrei but its sequence divergence with E. andrei was less than 1%, so, it belonged to E. andrei. Interpretation: This study shows the reliability of clubbing DNA barcoding experiments with classical taxonomy in supplementing and strengthening the traditional taxonomy for accurate identification of earthworms.

Aim: The study was conducted to find out the susceptible stage of tasar silkworm larvae to predation by stink bug and stage dependent feeding potential of stink bug over different instars of tasar silkworm. Methodology: Susceptibility of silkworms was studied by recording the daily larval mortality of all silkworm stages (1st to 5th instar) due to predation by E. furcellata. Stage specific predatory potential was estimated by recording the number of larvae required to complete each developmental stages (2-5th Nymphal instars and adult male and female). Results: Experimental results revealed that 1st and 2nd instar silkworms were most susceptible towards the attack of both nymphal and adult stages of stink bug whereas 3rd instar silkworms were moderately susceptible, however, third instar onwards susceptibility of tasar silkworm towards E. furcellata was negligible. Further stage specific cumulative predatory potential revealed that adult females of predatory bug were significantly more damaging to first instar silkworms (F= 125.20; df=5, 24; P= ≤ 0.0001) as compared to other stages by recording more larval consumption. Observations were also made on the second instar silkworms and it was observed that female adults were again superior over other stages of predatory stink bug (F= 135.30; df=5, 24; P= ≤ 0.0001). Similar trend of feeding potential was also recorded on 3rd instar silkworms; however, the rate of feeding was comparatively lesser than the first and second instar silkworms. Interpretation: Early instar silkworms were less defensive to predators attack, and were highly vulnerable to stink bug, however, as silkworm reached third instar, larvae started depending themselves by rapid head/thoracic movement to ward off the stink bugs. Significant difference in the feeding potential between different developmental stages was observed and adults being superior in feeding indicates their higher nutritional requirements as they need to be fit for reproductive performance to continue their progeny.

Far from home: bat activity and diversity in row crop agriculture decreases with distance to potential roost habitat
Authors: Hunninck Louis , Coleman Kjirsten , Boman Melissa , O'Keefe Joy
Published: September 2022

As demand for food increases, agricultural production is poised to
increase dramatically. Pesticides are commonly used to maintain high
crop yield, though they have several drawbacks, including reduced
efficacy over time and harmful effects to human and ecosystem health.
Bats are highly effective predators of crop pests and have great
potential to reduce crop damage resulting from insects. However, few
studies have investigated how pest control by bats might change over
large expanses of continuous row crop agriculture, which is common in
the Midwest. Agricultural landscapes offer few roosting opportunities
and could be difficult for bats to traverse, which might affect the
degree of ecosystem services provided by bats. We hypothesized that with
increasing distance into uninterrupted row crop agriculture 1) bat
activity would decrease and 2) bat species richness would decrease, but
that these effects would be buffered when insect pest abundance is high.
We deployed 50 acoustic bat detectors over 10 transects in east-central
Illinois from July to September 2021. In each transect, we placed
detectors on crop field edges at increasing distance from a large
riparian corridor assumed to be frequented by bats. Bat activity was
high across the landscape but declined by 56% from the forest edge to
4000m into row crop agriculture, while bat diversity decreased by 34%.
Pest abundance seemed to decrease overall bat activity but had no effect
on bat diversity. These results indicate that bats, although able to
have a large effect on crop pest reduction, might not be as efficient in
suppressing crop pests in vast uninterrupted agricultural landscapes
which offer scant roost availability. Our work will inform
recommendations to landowners and private lands managers on ways to
increase bat access to roosts and forest cover near agricultural areas,
thereby enhancing the potential for bats to provide pest control
services.

Published: September 2022

This research aimed to investigate which factors contribute to the work
engagement of preschool, elementary, and middle school teachers in Croatia.
Factors contributing to work engagement include social, work-related
factors, and demographic characteristics. A total of 548 teachers
participated in the research. The results indicated differences in work
engagement between the three groups of teachers, with preschool and primary
teachers reporting higher absorption and dedication compared to middle
school teachers. The length of working experience was positively related to
vigour and absorption. As for the social factors, children and parents
proved to be factors contributing significantly to work engagement, while
administration and colleagues did not prove relevant for any component of
work engagement. It is possible to conclude that quality work with children
and parents contributes to higher engagement, as does job security and lack
of time pressure at work.

Authors: AYDOĞAN İsmail , AKMAN AYDIN Eda
Published: September 2022

In this study, a wearable electromyogram (EMG) system on the forearm was designed to analyze finger movements for use in human-machine interfaces. The designed system measures the EMG signals without restricting the user's movements, analyzes these measurements through the software embedded in the system, and transmits the generated response to the output units to be controlled in real-time with wireless communication techniques. In the study, a three-channel EMG amplifier was designed and a system in which the NodeMCU V3 development board could be integrated was realized.With the system, the features of finger movements were obtained using the Mean Absolute Value (MAV) and classified using Support Vector Machines (SVM) and Random Forest (RF) methods. In offline tests, 99.47% accursacy with RF and 98.2% accuracy with SVM were obtained. The RF algorithm with 99.47% accuracy in offline tests was selected and integrated into the embedded system for online tests. In the online tests performed with five volunteers, the system was able to analyze finger movements with an average accuracy of 92.16%, and the commands associated with the finger movements analyzed by the system were sent to the clients with the User Datagram Protocol (UDP), and the related movements were displayed on the output unit interface. The system can work in real-time with a delay of 90 ms and instantaneous movements can be seen visually on the designed output unit interface. This study is an important step in the detection of muscle diseases, the control of EMG-based wearable prosthetic systems, and the design of unmanned vehicles that can be controlled by finger movements.

Published: September 2022

Background and purpose: Uncemented total hip arthroplasty (THA) is associated with periprosthetic bone loss. In a secondary outcome analysis from a randomized controlled trial, we studied whether denosumab can prevent loss of acetabular periprosthetic bone mineral density (pBMD) in patients who received a trabecular metal cup during uncemented THA.Patients and methods: 64 patients (aged 35–65 years) with unilateral osteoarthritis of the hip were randomized to 2 subcutaneous injections with denosumab or placebo, given 1–3 days post-surgery and 6 months post-surgery. Acetabular pBMD was measured in 5 regions of interest (ROIs) by dual-energy X-ray absorptiometry. Serum markers for bone metabolism were analyzed. Periprosthetic osteoblastic activity, measured as standardized uptake values (SUVs) by [18F] positron emission tomography/computed tomography, was evaluated in 32 of the 64 study patients.Results: After 12 months, patients treated with denosumab had higher pBMD compared with the placebo-treated patients in 4 of 5 ROIs and in sum of ROIs 1–5. After 24 months, the effect on pBMD for patients treated with denosumab declined. Serum markers declined pronouncedly up to 12 months in patients treated with denosumab, but rebounded above baseline levels after 24 months. Patients treated with denosumab had statistically significantly lower SUVs in all ROIs, except ROI 5, after 6 months.Interpretation: Based on this exploratory analysis of secondary endpoints the application of denosumab seems associated with preserved acetabular pBMD, reduced bone metabolism and attenuated periprosthetic osteoblastic activity. However, given the known rebound affects after discontinuation of denosumab treatment, these effects cannot be expected to persist. If prolonged treatment or shift to other regimes would be beneficial to reduce the risk of cup loosening is yet to be investigated.
Central Airway Obstruction due to Hematologic Malignancies, Diagnosis and Local Treatment - A Narrative Review
Authors: A Fantin
Published: September 2022

Background: Malignant hematologic diseases may present with rare features. One of these is the first manifestation as a central airway lesion whose symptoms could be mistaken for asthma, chronic obstructive pulmonary disease, non-resolving or recurrent pneumonia, foreign body inhalation or both acute and chronic heart failure. The age of onset of the symptoms does not help in the differential diagnosis, leaving the clinician with a diagnostic dilemma, frequently clarified by invasive sampling. Current evidence of this group of entities is based predominantly on case reports. The aim of this work is to report a non-systematic review of haematological pathologies that can present themselves as an obstruction of the central airways, the possible ways in which it is possible to diagnose and treat them locally. Methodology: This revision work is the result of a critical analysis of the existing literature, carried out by collecting the main bibliographic entries in different languages present in international scientific databases relative to the topic of interest. All the arguments have been elaborated by the authors and critically re-proposed, in a non-systematic way (narrative revision).
Hematology as an Analytical Tool in Forensic Science
Authors: K Gupta
Published: September 2022

Blood is one of the most important biological evidence found at a crime scene. In a violent crime , the blood sample obtained may belong to the victim, the suspect(murderer) or any other eyewitness. A proper analysis of blood samples obtained at a crime scene may contribute to clarify the circumstances under which the crime would have been committed. The information obtained by studying the blood sample may point the criminal investigation in the right direction and can help solve the crime. Hematology refers to the study of blood and it can play an important tool in analysing the crime. The blood analysis begins with the presumptive tests to confirm that a given sample is blood. Then precipitin technology may be used to find the species to which the blood belongs. Methods like DNA fingerprinting may be used to match the blood at crime scene with the blood of suspect to get a step closer to finding the criminal. We report here few of the analysis of blood that can be done to possibly fasten the process of case solving and find the right criminal.

The article discusses various methods for calculating the vehicle speed based on photo and video materials during the reconstruction of a road traffic accident. Some foreign methods of calculating the vehicle speed from photo and video materials are analyzed, the calculation being done in relation to the location of the object under study and the recording device. The authors show the application of one of the methods in practice. The Amped Five software product has processed the video recording under study, which is necessary for further assessing of the vehicle speed. As a result, there has been made a calculation of the speed of the motorcycle using the technique of moving the object to the specified distance in relation to the stationary objects by video recording. The obtained value of the motorcycle speed coincided with the calculated value obtained using the method based on the work of forces on movement», which confirms the reliability of the values obtained. Thus, as the analysis shows, the use of photo and video materials in the investigation of a road traffic accident can significantly increase the level of reliability and correctness in the reconstruction of the accident.

Then, students feel more interested and comfortable speaking in English when using video call conversations (VCC).
Tiempo y usura en los escolásticos
Authors: Trincado Aznar Estrella
Published: September 2022

Este artículo estudia la evolución de la doctrina de la usura desde la escolástica hasta el siglo dieciocho. Se estudian los antecedentes en la economía Antigua que llevaron a plantear los principios escolásticos y el concepto de precio justo y usura, en que tiempo y espacio se consideraba un “bien común”. En el salto al siglo dieciocho desaparece esa sensación espacio-temporal común, planteándose los bienes públicos como una suma de intereses privados. Sin embargo, esa visión moderna cierra la vía del reconocimiento mutuo que los escolásticos atisbaron.
“No somos nacionalistas; somos Tacuara y se acabó”. La experiencia tacuarista durante la Revolución Argentina (1966-1973)
Authors: Albornoz Celina
Published: September 2022

Este artículo aborda las rupturas y continuidades en la cultura política del Movimiento Nacionalista Tacuara luego de 1966, período que ha sido considerado por la historiografía como posterior a la historia de la agrupación. En esta etapa, “de reconfiguración y declive” (1966-1973), el eje se trasladó desde Buenos Aires a la provincia de Santa Fe. Se concluye que en esta fase tuvo lugar un desencanto por el nacionalismo, que llevó al replanteamiento de la noción de “revolución nacional”, que había articulado al movimiento en los años anteriores. Para trazar esta periodización, serán cruciales el descentramiento de la historia de Tacuara a través de la inclusión del espacio santafesino y el uso del concepto de “cultura política”.

Published: September 2022

A lumen efficiency (LE) simulation model with the Monte Carlo method is introduced to the white-light-emitting diode devices that utilize the red LED (light-emitting diode) dyes instead of red-emitting phosphors (R-WLEDs). By simulating this model, the desirable spectrum-related indices and photometric efficiencies, which are adequate for superior chromatic consistency (or R
f
> 97), can be accomplished for R-WLEDs under the correlated color temperature (CCT) range of 5000–8000 K. The structure of the R-LED has LEDs in red and blue colors (650 nm and 448 nm) combined with phosphors possessing yellow and green emissions (586 nm and 507 nm). In comparison with pc-WLEDs (WLEDs operating with conversion phosphors) and QD-WLEDs (WLED devices with quantum dots), pc/R-WLED devices could present its outperformance to the others and become a promising way to achieve remarkable chromatic generation, particularly under the condition of small color temperature limit, and act as a substitute for the pc-WLED devices.

In this study, we report a mild and controllable preparation method for graphene oxide (GO) and ZnO ultrafine powder, respectively. On this basis, reduced graphene oxide (rGO)/ZnO composite powder for the photoanodes of dye-sensitized solar cells (DSSCs) was synthesized by chemical reduction method. Phase composition, microstructure, chemical structure, conductivity, and specific surface area were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FT-IR), Raman, and Brunauer-Emmett-Teller (BET) method, respectively. Photoelectric performance of DSSCs was studied by the current density-voltage (J-V), electrochemical impedance spectra (EIS) photoelectric test system. As rGO possesses higher adsorption capacity and excellent conductivity, hence it may effectively promote separation of electrons and holes, transmission ability of electrons and holes, and utilization of the light. By contrast, the as-synthesized zinc oxide (ZnO) may increase adsorption capacity of dye molecules, so photoelectric conversion efficiency (PCE) of the solar cells is increased by means of synergistic effects. When adding rGO in the rGO/ZnO composite powder at 1.25 wt%, PCE reaches to 6.27%, an increase of 20.6% more than that of pure ZnO as the photoanode.

This study focuses on the future changes to the urban form around the Salaya railway station, which will be developed as a terminal station of the Bangkok metro service. The purpose is to investigate stakeholder attitudes to the transit-oriented development (TOD) approach to the station premises. The attitudes of local businesses and key stakeholders to joint programs on infrastructure development and the surrounding area are identified as local businesses encouraging the collaborative urban regeneration program. The approach uses scenarios as a tool for participatory planning to help identify future applications, including a workshop in two parts. The first part was conducted using group interviews with local entrepreneurs to raise the idea of the collaborative urban regeneration program. The second part was an evaluation of the program by the three key stakeholder groups: municipality, railway operators, and real estate investors. The scenarios evaluated by the key stakeholders indicate the different attitudes to the collaborative urban regeneration program depending on the role of each stakeholder. The collaborative program developed by local entrepreneurs can be classified by economic and physical factors. The findings suggest a common aspect for future collaboration in marketing strategies, such as advertising representing localness, as both local entrepreneurs and key stakeholders mostly agreed on the program. Disagreement on collaborative urban regeneration depends more on the specific role of the company or organization.
Quando o falante faz Linguística

Tratamos neste ensaio teórico do saber linguístico do falante para além de sua competência linguística, focando especificamente em situações em que os falantes refletem sobre seus usos linguísticos. Baseando-se na nomenclatura empregada por Franchi (2006) e Geraldi (2013), defendemos que é possível encontrar na internet situações em que o falante emprega uma reflexão sobre sua língua de maneira particular, exercendo atividades epilinguísticas, e também situações em que o falante traça uma reflexão mais generalizada sobre questões linguísticas, através de atividades metalinguísticas, mesmo não empregando termos técnicos da área. Essas situações circulam sob diversos gêneros e inclusive alcançam repercussão através de virais, como memes, tuítes e tirinhas, e ilustramos neste trabalho casos assim através de comentários coletados no Twitter. Defendemos que essa sabedoria gramatical deve ser valorizada, tanto em sala de aula quanto no espaço acadêmico. Ilustramos a pertinência desse tipo de texto em práticas de divulgação científica, através de post produzido por uma das autoras. Discutimos também a possibilidade de incluir esses textos em aulas de língua portuguesa, especialmente considerando a etapa de descoberta proposta na metodologia de Lobato (2015). Da mesma forma, afirmamos que a manipulação de propriedades linguísticas por pessoas não especialistas pode ser acolhida em propostas de ciência cidadã, abrindo portas para um fazer científico mais participativo.

Palliative care is often started late in patients with life-threatening conditions, particularly in patients with advanced cancer. However, with the emergence of the early palliative care (EPC) paradigm, their quality of life (QoL) may be better. Although several previous meta-analyses support the effectiveness of EPC in increasing QoL, essential issues related to the optimisation of EPC interventions are still needed. A systematic review and meta-analysis of randomised controlled trials (RCTs) were conducted to determine the effectiveness of EPC on the QoL of patients with advanced cancer. PubMed, ProQuest, MEDLINE through EBSCOhost and Cochrane Library and clinicaltrials.gov (register website) were searched for RCTs published before May 2022. Data synthesis used the Review Manager 5.4 to generate pooled estimates of effect size. A total of 12 empirical trials met the eligibility criteria and were included in this study. The results showed that EPC intervention had a significant effect (standard mean difference = 0.16, 95% confidence interval: 0.04, 0.28, Z = 2.68, P < 0.05). However, the secondary outcomes showed including mood (mean difference = −0.90, 95% CI: −2.32, 0.51, P > 0.05) and symptom controls (MD = −1.49, 95% CI: −3.81, 0.81, P > 0.05) had no significant effect. EPC is effective in improving the QoL of patients with advanced cancer. However, other outcomes still need to be reviewed, because the review of QoL is not enough to generalise the benchmarks for the effectiveness and optimisation of EPC interventions. Another notable aspect is to consider the most effective and efficient duration for starting and ending EPC interventions.

The article analyzes the main features of the EU energy policy in the building stock, which is aimed at achieving climate neutrality by the middle of the current century. The main directions and technologies related to the energy and climate safety of energy supply systems of the building stock are highlighted. At the same time, special attention is paid to the need to transition to energy- and environmentally-efficient decarbonized centralized and decentralized energy supply systems with the prospect of full electrification of heat supply systems. The importance of further intensive development of energy storage systems in daily and seasonal cycles is indicated as an important condition of the carbon-free energy market. The possibility of using ecologically improved technologies of heat generation on natural gas within certain time limits is also noted.
CONCEPTUAL MODEL OF BALANCED DEVELOPMENT OF ENTREPRENEURSHIP IN THE SPHERE OF RECREATION AND HOTEL AND RESTAURANT BUSINESS OF CARPATHIAN ECONOMIC DISTRICT

Published: September 2022

Introduction. In the conditions of an unstable economic situation, aggravation of social, political, and environmental problems, an important element of the formation of an effective model of enterprise development in the field of recreation and hotel and restaurant business of the Carpathian Economic Region is to ensure its balanced development by combining and harmonizing the interests of economic development, the unique landscape and biological diversity of Ukrainian Carpathians, as well as the original culture and traditions of the local population. The purpose of the article is to formulate recommendations aimed at building a conceptual model of balanced development of entrepreneurship in the field of recreation and hotel and restaurant business of the Carpathian Economic District. The main idea of the concept of balanced development is to ensure the development of entrepreneurship in the field of recreation and hotel and restaurant business based on the principles of socially significant business performance, achieving economic efficiency and ensuring environmental sustainability. More modern, and one that takes into account the need for a systemic approach to model development, is an approach focused on ensuring inclusive development. The expediency of applying the principles of inclusive development in the model of balanced development of entrepreneurship in the field of recreation and hotel and restaurant business of the Carpathian Economic Region is justified by the fact that: entrepreneurship in the field of recreation and hotel and restaurant business is connected with the involvement of recreational and natural resources of the public, not individual level consumption; the demand for recreation services is formed and, accordingly, implemented within certain social groups, which are differentiated by the level of income and the specifics of consumption. The concept of balanced development of entrepreneurship in the field of recreation and hotel and restaurant business of the Carpathian Economic District is aimed at ensuring the development of entrepreneurship in the field of recreation and hotel and restaurant business based on the principles of socially significant business performance, achieving economic efficiency and ensuring environmental sustainability. Its purpose is to ensure the inclusive development of entrepreneurship in the field of recreation and the hotel and restaurant business of the region and, on its basis, to improve the qualitative and quantitative parameters of the development of the Carpathian Economic District. Achieving the specified parameters will make it possible to ensure the employment of the population, increase the volume of services provided and improve their quality characteristics, and increase the amount of tax revenues.
