Published: August 2022

Facial aging is a continuous process, accompanied by changes in facial structures that culminate in the appearance of wrinkles, infraorbicular bags and skin sagging. The use of polydiaxone spiked threads (PDO) has been showing satisfactory results as a minimally invasive modality for the treatment of facial ptosis. Clinical observations suggest that the effects of facelift with PDO threads are prolonged when combined with other aesthetic treatments. Considering this, the present work aims to present a clinical case where the association of techniques for facial rejuvenation was carried out, using PDO threads, hyaluronic acid for facial filling and botulinum toxin. A 61-year-old female patient sought professional help with interest in performing minimally invasive cosmetic procedures for facial rejuvenation. For the first clinical session, the application of botulinum toxin and the insertion of PDO spiked threads were planned. It was applied 56U of botulinum toxin to the upper third of the face and 8 spiculated threads were inserted for face lifting in the middle third of the face with the aim of reducing ptosis in the adipose compartments. After 2 months, a new clinical session was performed in order to fill in and add volume in strategic points of patient’s face. Hyaluronic acid was applied in the premaxilla region. Patient presented a rejuvenated facial appearance after the procedures performed, reflecting evident improvements in the quality of life, resulting in physical and emotional well-being for the treated patient.

Authors: D. Younus Mustafa , F. Bahjat Omar
Published: August 2022

In this study forty isolates of Pseudomonas aeruginosa were recorded from burn patients admitted to West Emergency Hospital in Erbil city. Isolates from burn samples were identified using cultural, morphological, biochemica1 tests. Antibiotic sensitivity testing was performed for all isolates using l4 types of antibiotics including Ampicillin (AMP), Chloramphenicol (C), Amoxicillin-clavulanic acid (AMC), Cefotaxime (CTX), Penicillin (P), Aztreonam (ATM), Meropenem (MEM), Tobramycin (TOB), Gentamycin (CN), Amikacin (AK), Ciprofloxacillin (CIP), Ceftazidim (CAZ), Tetracycline (TE) and Imipenem (IMP). The antibiotic imipenem was the most effective against P. aeruginosa isolates. The resistance rates of the isolates to these antibiotics were l00% for AMP, CTX, P, AMC, and C. For ATM 32.5%, for MEM 42.5%, for TOB, AK and CN 45%, for CIP 62.5%, for CAZ 67.5%, and for TE 80%. The plasmid profile of 5 antibiotic-resistant isolates (Pl, P3, Pl3, P29 and P38) were screened, results showed a single band with a molecu1ar weight more than l0 kb for a1l 5 isolates. Moreover five isolates (Pl, P3, Pl3, P29, and P38) were chosen for the transformation process and the identification of antibiotic resistance genes, using 1aboratory strain Escherichia coli DH5-α with plasmid DNA purified from these isolates. The transformation process was completed successfully, and the results revealed that the resistance genes for (Amikacin, Ampicillin, Cefotaxime, Tobramycin, Gentamycin, Chloramphenico1, Amoxicillin- cluvanic acid, Ciprofloxacin, Tetracycline, Penicillin, Ceftazidime, Azetreonam, and Merpenem) 1ocated on plasmid DNA for Pl isolate, whi1e for P3 (Amoxicillin- cluvanic acid, Ampicillin, Amikacin, Ciprofloxacin, Merpenem, Tobramycin, Chloramphenicol, Gentamycin, Tetracycline, Cefotaxime, and Penicillin) 1ocated on plasmid DNA. On other hand the resistant genes for (Amoxicillin- cluvanic acid, Ampicillin, Amikacin, Ciprofloxacin, Tobramycin, Chloramphenico1, Gentamycin, Tetracycline, Cefotaxime, and Penicillin) were located on plasmid DNA for Pl3. Moreover (Amoxicillin- cluvanic acid, Ampicillin, Amikacin, Ciprofloxacin Merpenem, Tobramycin, Chloramphenicol, Gentamycin, Tetracycline, Cefotaxime, and Penicillin) for P29 were located on plasmid DNA, lastly for the P38 the resistant genes were located on plasmid for (Amikacin, Ampicillin, Cefotaxime, Tobramycin, Gentamycin, Chloramphenicol, Amoxicillin- cluvanic acid, Ciprofloxacin, Tetracycline, Penicillin, Ceftazidime, Azetreonam, and Merpenem).

Philosophy of Life in Rabia
Authors: Hooda Sharon
Published: August 2022

Rabia Basri, was the first female Sufi Saint of Islam, also known as Rabia al-Adawiyya. Rabia’s views are based on God's compassion, claiming and preaching that love is the only road to God. There is no clear distinction between good and bad, for it is reduced to Unity, and God is the only writer of mankind's actions. God is the one who determines man's will.. The aim of a Sufi's life is only to love God and pursue His grace and happiness, which is impossible unless the person serves humanity.

Authors: Lee Teh Phoey , Choy Ker Woon , Ching Low Yeh , Boon Ooi Pei
Published: August 2022

Introduction: COVID-19 pandemic leads to working from home culture. Long hours of the static sitting posture on improper chairs at home may lead to low back pain (LBP). This study aims to study the prevalence of LBP in sitting position during usage of portable computing devices and the association of LBP and sitting behaviour in home environment settings. Methods: An online questionnaire cross-sectional study was conducted, and the Visual Analog Scale (VAS) and Modified Oswestry LBP Disability questionnaire were adapted. The association between the factors such as duration of chair break, type of posture and the incidence of LBP were examined. Results: Majority of the 279 participants who participated in the study experienced LBP while working from home. We found strong evidence for suggesting a significant statistical association between duration of chair break (chi-squared value = 19.86, p-value = 0.006) and LBP. Most of the participants were categorised as having minimal disability, followed by moderate disabilities and only around 1% were crippled. ODI for sitting posture was statistically significant (Za value = 16.35, p = 0.022). Posture with round back and increased kyphosis with the feet supported on the floor is the highest reported posture with VAS score. VAS for duration of sitting posture was statistically significant (Za value = 10.37, p = 0.035). Those who spent only 5 – 30 minutes in the posture reported significantly lower VAS score compared to more than 30 minutes in the posture. Conclusion: Correct posture and taking chair breaks are essential to reduce the incidents of back pain and functional disabilities within the home working environment. The outcome of our research can be evidence-based information to occupational health specialists to optimise the current standard of practice and guidelines in working from home management.
The Roles of Balanced Scorecard in Improving Performance Accountability System in Indonesian Government Organizations
Authors: Ari Erawan I Gede , Putra Fadillah , Sentanu I Gede Eko Putra Sri
Published: August 2022

Based on the evaluation report from the Ministry of Administrative and Bureaucratic Reform, the quality of the Indonesian government organisation’s performance accountability is still deficient. Therefore, several Indonesian government institutions have practised the Balanced Scorecard (BSC), a perspective-based performance management tool, to improve their performance accountability. This paper analyses how the Indonesian central government employs BSC and strategy maps to improve its performance accountability systems. A descriptive qualitative study concluded that Indonesian government agencies use different approaches to implement perspectives in the BSC, which they think are best suited to the characteristics of each government organisation. Indonesian government institutions generally implement BSC as a strategy execution tool, a measurement tool, and a performance accountability report. Therefore, these roles of BSC lead to an improved performance accountability system. The essential factors in developing BSC implementation are explained as well. However, this paper only primarily uses data from the Ministry of Finance and focuses only on the central government due to data limitations and time constraints. Therefore, future research is suggested.

Published: August 2022

Essential oil (EO) obtained by hydrodistillation in a Clevenger-type apparatus from aerial parts of Nepeta cataria L. var. citriodora (Becker), cultivated in Serbia was subjected to gas chromatography-mass spectroscopy (GC-MS) to determine the composition. Furthermore, N. cataria var. citriodora essential oil wastested to determine its antimicrobial, antioxidant, antihyperglycemic and anti-inflammatory activities in vitro.The antimicrobial activity was tested by broth microdilution method against 16 bacterial strains from American Type Culture Collection (ATCC). Four common tests for measuring in vitro antioxidant activity were used: 2, 2-diphenyl-1-picrylhydrazyl assay (DPPH), reducing power (RP), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and β-carotene bleaching assay (BCB). Antihyperglycemic activity was examined by using α-glucosidase inhibitory potential (AHgA), while anti-inflammatory activity (AIA) was determined by protein denaturation bioassay, using egg albumin. In total, 36 compounds were isolated and detected by GC-MS technique in N. cataria var. citriodora EO. The EO is mainly comprised of oxygenated monoterpenes (93.1%), and the main compounds were two monoterpenoid alcohols, nerol (38.5%) and geraniol (24.9%), followed by two aliphatic aldehyde, geranial (14.6%) and neral (11.0%). Antimicrobial activity of this EO shows growth inhibition of all tested bacteria strains, and exhibited good antioxidant, antihyperglycemic and anti-inflammatory activities. The EO obtained from N. cataria var. citriodora grown in Serbia shows valuable biological activity, indicating its potential for use as a supplement in everyday diet and as a natural preservative in food industry.

Objectives

Information on nurse educator education is scarce. The present study thus aims to provide an overview of the requirements for and standards of nurse educator education in six European countries in order to enable further reflection and promote discourse on the topic. Methods: A descriptive international cross-sectional comparative study was conducted across six European countries. Data were collected via an online questionnaire completed by experts in nurse educator education or in organisations with specialist knowledge about nurse educator preparation (n = 11). The data were analysed, compared, and condensed.

Results

The participating countries differ in terms of their educational requirements and the working environments they provide for nurse educators. Formal nurse educator education is available in three of the six countries. Furthermore, in the countries with formal education for nurse educators, differences exist in terms of the regulation and implementation of the education. The educational requirements of nurse educators in higher education are mostly not specific to nursing and are instead general requirements for professional (tertiary) or higher education.

Conclusions

The analysis reveals heterogeneous regulations, standards, and pathways in the education of nurse educators in the six different counties included in the study. Despite some formal and content-related similarities, no uniform picture of the educational requirements, programmes, or standards was identified. The results of this international comparative research confirm the need for further research that examines whether the education of nurse educators meets the global need both for skilled nurses and for more Europe-wide collaboration in nurse educator education.

Published: August 2022

Os restaurantes se constituem como potenciais geradores de resíduos sólidos, dadas as mudanças socioeconômicas e os hábitos de vida que levam ao aumento da alimentação fora do lar. Nesse cenário, os consumidores também exercem influência e, características sociodemográficas associadas, podem revelar um contexto em que a geração e o descarte de resíduos sejam melhores compreendidos. Diante disso, este estudo apresenta como objetivo principal caracterizar o perfil do público consumidor quanto à geração e a preocupação com os resíduos sólidos provenientes do consumo em restaurantes. A partir de uma pesquisa quantitativa, 406 consumidores foram investigados em suas características sociodemográficas associadas à consciência e à preocupação com a geração e descarte de resíduos sólidos em restaurantes. Os dados levantados foram tratados estatisticamente. Os resultados apontam que o perfil consumidor, em conjunto com seus hábitos, tem grande influência na consciência e geração de resíduos sólidos em restaurantes. Constatou-se que maiores níveis de formação e maior faixa etária estão associados a um menor desperdício e descarte de resíduos alimentares, assim como a uma maior consciência e preocupação em relação aos resíduos sólidos gerados nesses ambientes.

The Role of international Organizations in the Process of countering Cybercrime
Authors: Gorelik Ilya Borisovich
Published: August 2022

The subject of the study is the role of international organizations in the formation of an international legal system for countering cross-border cybercrime. The purpose of the study is to identify current trends in the work of international organizations in the field of the formation of regional and global legal systems for countering cybercrime. The system approach and formal legal approach are used as the main research methods. As a result of the study, specific features of regional international organizations and legal problems of countering cybercrime were identified, the question of the applicability of existing international law to cyberspace was analyzed. In particular, it is noted that at the moment modern international law is not capable of adequately and effectively countering cybercrime. The absence of a universal international legal act regulating the process of combating cybercrime is emphasized. On the other hand, the positive role of individual international organizations in the formation of the international legal system of counteraction is noted. In particular, the study describes the practice of forming expert groups by such organizations, as well as assistance to other regional international organizations in the process of creating their own international legal systems. One of the main conclusions is the conclusion that the absence of a universal UN legal document creates certain difficulties in the course of interstate coordination of procedural actions of law enforcement agencies and interaction of relevant international organizations. The author also concludes that the law-making experience of individual international organizations can be taken as a basis for the creation of a universal international legal act regulating the fight against cybercrime.

Traffic on public wireless networks is mostly unencrypted. Most users are usually unaware of the risks involved, and providers of public Wi-Fi hotspots do not pay attention to this, focusing only on convenience and ease of user to access the network, while ignoring the protection of user data.Cybercriminals effectively use existing security vulnerabilities in public Wi-Fi spots to intercept network traffic and steal sensitive data. To ensure effective counteraction to hacking, an important task is to analyze methods and technologies for detecting and combating such cybercrime attacks.The literature and research reviews of public Wi-Fi spots shows that the justification for the feasibility and effectiveness of using a method or technology of protecting Wi-Fi spots depending on the type of threat, network structure and type is not given enough attention.The aim of this work is to evaluate the effectiveness of modern methods and technologies of protecting public Wi-Fi networks based on the analysis of current threats and vulnerabilities and develop recommendations for their use in deploying and supporting various types and features of public Wi-Fi networks including user devices.Based on the analysis of the most common vulnerabilities and threats of public Wi-Fi spots, features, advantages and disadvantages of currently used technologies and methods to ensure adequate protection of wireless networks, it was recom-mended to implement WEP, WPA, WPA2, WPA3 and OWE technologies depending on the type of user activity and amount of confidential information, the availability of support for a particular end-user protection technology and the relevance of security protocols provided by a particular security technology.

The creation of effective demanganization technologies by the development of new and intensification of known processes of manganese removal from natural waters are currently of increasing importance.The search for promising ways to demanganize water to regulatory values is a topical issue for the modern water treatment domain.Recent publications of methods for extraction of manganese ions from water by sorption, membrane, ion exchange methods were reviewed. The prospects of application of oxidative methods for water demanganation are shown.The purpose of the article is to investigate the manganese ions removal methods from water during their oxidation by sodium hypochlorite and to establish the dependence of the efficiency of demanganization on the consumption of oxidizing agent and the concentration of manganese ions in water.The study presents the application of sodium hypochlorite as an oxidant in the purification of artesian water from manganese ions. It was determined in static conditions that the degree of manganese removal is affected by both its initial concentration in water and the dose of sodium hypochlorite. Water purification process is more efficient with initial manganese concentrations above 5 mg/dm3. At a manganese ion concentration 30 mg/dm3, its complete removal was achieved in 4 hours of settling at a stoichiometric ratio of manganese and sodium hypochlorite in water and at any excess of oxidant. The process of manganese ions oxidation in artesian water by sodium hypochlorite depending on its dose and contact time was studied. The dose of oxidant for the removal of manganese ions from artesian water was also determined. Thus, the research allowed to improve the methods of water purification from manganese ions during their oxidation by sodium hypochlorite and found that the water purification efficiency increased both with increasing consumption of oxidizing agent and increasing the concentration of manganese ions in water.

The objective of the present study is to justify the possibility of constructive and analytic solution to the inverse problem of cyclographic modeling of a curve of space R3 and development of a respective algorithm. The orthogonal projection and the two components of the cyclographic projection of a spatial curve form a triad of elements in plane z=0. These elements are the result of the direct problem solution and constitute the basis for the inverse problem solution. The direct problem consists in construction in plane z=0 of a cyclographic projection (a model) of a given spatial curve, while the inverse problem consists in determination of a spatial curve given its cyclographic projection. Insufficient knowledge on the inverse problem as well as its relevance in practical applications, e.g. in cutting tool trajectory calculation for pocket machining of mechanical engineering products on NC units, make urgent the definition and the solution of the inverse problem. In the present paper a simple convex closed curve is considered as the given cyclographic projection. It is proven that there exists a unique spatial curve, for which the given curve constitutes a cyclographic projection. The algorithm for the inverse problem solution is demonstrated on examples.

Published: August 2022

This article discusses the development of a method for determining reactions in the hinges of a manipulator, based on the classical principle of release from bonds in the example of its main part. A model of a manipulator has been compiled, in which, in the general case, a force F of arbitrary orientation acts on the working platform. The design scheme of the manipulator is compiled and a complete calculation is made under the action of the horizontal component force Fx . By analogy, the reactions from the action of the horizontal Fy and vertical Fz components of forces are determined and general dependencies are derived. Knowledge of the numerical values of the found reactions in the hinges of the manipulator will allow, according to known hypotheses, to calculate this manipulator for strength and rigidity.

The modernization of the method of synthesis of motions of manipulators by speed vector allows to exclude motions the emergence of dead ends in the process of computer simulation. The developed algorithm is based on the use of a database characterising the values of kinematic parameters that specify the permissible instantaneous states of the mechanism of the manipulator at different positions. The graphical representation of the hypersurface of the reflective relationship of the specified parameters from the values of the generalized coordinates is made. On the basis of this, a method for determining the above kinematic parameters is proposed, which makes it possible to reduce the time for calculating intermediate configurations on a given trajectory of the output link and to eliminate the occurrence of deadlock situations.

In this work, we carried out a comprehensive study of the morphology, chemical composition, electronic structure, and electrochemical characteristics of a nanocomposite based on carbon nanotubes (CNTs) and manganese oxide particles. The study of the electronic structure of the nanocomposite, performed by X-ray photoelectron spectroscopy (XPS), showed that manganese is in two chemically nonequivalent states in MnO2-x and in KMnO4 . It has been established that manganese oxide is deficient in oxygen. In the course of electrochemical tests performed by the method of cyclic voltammetry (CVA), it is shown that the electrode based on the nanocomposite showed high arial capacitance values of 320 mF∙cm–2 at a potential scan rate of 5 mV∙s–1 and a low gravimetric capacitance of 14 F∙g–1. With an increase in the potential scan rate, the specific capacitance of the nanocomposite significantly decreased relative to CNTs, which is due to a number of reasons: (i) insufficient porosity of the electrode surface; (ii) a decrease in the amount of MnOx nanoparticles in the electrode and their dissolution in the electrolyte during charge-discharge processes.

Based on the previously compiled physical and mathematical model of the vortex tube workflow, the calculation of the thermogasodynamic characteristics of the vortex tube with known geometric dimensions and their comparison with experimental data was carried out. The calculations take into account the exchange of work and heat between the axial and peripheral gas layers. The exchange of work is carried out due to the transfer of kinematic energy from the axis to the periphery by viscosity forces when tangential stresses occur. The difference of thermodynamic temperatures when heat is supplied from the periphery to the axis is taken into account. These phenomena reduce the cooling effect of the flow coming out of the diaphragm.
