Authors: Çömez Saadet , Efteli Elçin
Published: March 2023

Objective: In this study, it was aimed to determine nursing students’ attitudes towards complementary and alternative treatment methods
Material and methods: A descriptive and cross-sectional study was carried out in the health sciences faculty of a university between February-March 2018. The sample consisted of first and fourth year students of nursing (n:197). The “Descriptive Information Form” and Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) were used to collect the data.
Results: In data analysis, descriptive statistics, student's t test and chi-square test were used. The mean scores the first and fourth year nursing students obtained from the overall HCAMQ were 32.69 ± 5.42 and 30.82 ± 5.84 respectively. There was a statistically significant difference between the first and fourth year nursing students in terms of the mean scores they obtained from the HCAMQ (p< 0.05). There was no statistically significant difference between the first and fourth year students in terms of their mean scores for the CAM and HBB sub-dimensions (p>0.05).
Conclusions: The results of the study demonstrated that the participating nursing students displayed positive attitudes towards the methods of complementary and alternative medicine at a moderate level. Their being knowledgeable about CAM methods is important. In order for nurses to be primarily responsible for patient care and to provide care holistically, their being knowledgeable about CAM methods, and informing their patients about the CAM. Therefore, we recommended that the undergraduate nursing curriculum should also include information about CAM, and students should be provided with educational opportunities about different methods.

COMPARISON ON STUDY OF LITHIUM ION SERIES AND LEAD ACID SERIES CHARGING AND DISCHARGING CHARACTERISTICS

Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently. However, as the number of batteries in series increases, so does the possibility of slight differences in capacity. These differences can result from age, storage history, temperature variations or abuse .Fully charged batteries should never be mixed with discharged batteries when charging batteries in series. The discharged batteries should be charged before connection .When a single constant voltage charger is connected across an entire high voltage string, the same current flows through all cells in the string. Depending on the characteristics of the individual batteries , some may overcharge while other remain in a slightly undercharged condition .To minimize the effect of individual battery differences , use batteries of the same age , manufacturer , amp hour , and history and , if possible ,charge in strings of no greater than 24 or 48 volts . On the other hand it is highly recommended to charge lithium batteries in series with a multi-bank charger. This means each battery is charged at the same time but completely independent of the other. Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. One might even decide to reduce the target voltage to preserve the electrode. Li-ion does not need to be fully charged as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge because a high voltage stresses the battery. In a lithium-ion battery, overcharging can create unstable conditions inside the battery, increase pressure, and cause thermal runaway. Lithium-ion battery packs are required to have a protection circuit to prevent excessive pressure build- up and cut off the flow of ions when the temperature is too high. A partial charge and discharge will reduce stress and prolong battery life. It is recommended to avoid full cycles and stay between 100% and 50% DOD (0-50% SoC).

Published: March 2023

Синдром инфузии пропофола (СИП) — редкое, но чрезвычайно опасное осложнение применения пропофола, характеризующееся высоким уровнем летальности. Патогенез СИП представляет собой сочетание усиленного липолиза, нарушения процессов окисления жирных кислот и дисфункции митохондриальной дыхательной цепи. СИП, как правило, развивается у пациентов с критическими расстройствами при продолжительной инфузии пропофола в высокой дозе и манифестирует лактатацидозом, рабдомиолизом и острой циркуляторной недостаточностью. Специфическое лечение СИП отсутствует, а прогноз во многом определяется способностью клинициста своевременно распознать синдром и прекратить введение пропофола. Обзор рассматривает современные представления о патогенезе, клинических проявлениях, методах предупреждения и интенсивной терапии синдрома и в целом призван повысить настороженность и расширить представление практических врачей о данной проблеме.

Propofol infusion syndrome (PRIS) is rare but extremely dangerous complication of propofol administration that is characterized by increased mortality level. Pathogenesis of PRIS is represented by the conjunction of intensifi ed lipolysis, disturbances of fatty acid oxidation and impaired mitochondrial respiratory chain function. PRIS typically develops in patients with critical conditions receiving continuous high-dose propofol infusion and presents as lactate acidosis, rhabdomyolysis and acute circulatory failure. For PRIS there is no specifi c treatment and the prognosis is largely determined by an ability of the clinician to recognize the syndrome early and stop propofol administration. Th is review provides a modern insight into pathogenesis, clinical presentations, preventive measures and intensive care of the syndrome and is generally intended to raise an alertness and improve understanding of the problem among practicing physicians.

This article aims to map the scales validated in the international literature for the assessment of learning environments. A systematic literature review was carried out in articles from the web of Science database in the period from 1970 to 2020. After completing the three stages proposed by Tranfield, Denyer, and Smart (2003), 94 articles were selected to compose the final sample. Most of the articles analyzed were published from 2011 to 2020 (54.2%). Barry J. Fraser is the author who published most of the articles from the analyzed sample (10), which confirms his representativeness in studies involving the subject. Most articles involve the area of Education and Educational Research (78.7%). Twenty scales used to assess the learning environment were identified. The What Is Happening In This Class? Instrument is the most cited and most used in the articles analyzed. We also identified that the six dimensions of this instrument appear in four or five different scales, which reveals its contribution to the construction of assessment scales. The study results can assist in the development of a multidimensional scale of learning environments.

Recycling of spent silver electroplating solutions has been investigated via electrowinning and electrorefining in comparison to zinc cementation technique in this research. Two different compositions of transparent and dark waste solutions were used having the remaining silver contents of 17.71 g⸳L-1 and 33.36 g⸳L-1 respectively. The waste solutions were used as an electrolyte in the first step of electrowinning at low current density of 0.015 A⸳cm-2. It was found that increasing electrowinning time from 4 h to 24 h increased the recovery of silver cathode for both types of waste solutions. The optimum electrowinning time was higher than 8 h, giving the recovery of higher than 97.5% and 98.5% purity for 24 h electrowinning. Through the subsequent electrorefining, the electrowon silver cathode was set as the anode, while HNO3 + AgNO3 electrolyte containing high silver content of 120 g Ag/L was used. By controlling the potential at 0.8 V, silver crystal of high purity > 99.9% was obtained. The highest recovery was 99.11% when using silver cathode obtained from electrowinning of the transparent waste solution. Zinc cementation however led to loss of silver in the precipitate form on the zinc metal surface, giving only 86.16% recovery.

Most of natural topaz is colorless; thus, methods of color enhancement are widely used for coloring this mineral. Currently, blue color is obtained by cobalt diffusion due to drawbacks in existing coloration methods. In this study, optimum conditions suitable for Cobalt diffusion in Sri Lankan colorless topaz were investigated and coloration mechanism was elucidated. The diffusion agent was prepared by mixing CoCO3 with Na2CO3, CaCO3 and carbon powder and diffusion was carried-out by varying the temperature and soaking time. Chemical analysis, UV-Vis absorption spectrum, infrared absorption spectra, and Raman peaks of diffused and non-diffused topaz were tested. The results clearly indicated that the optimum condition for Co diffusion in Sri Lankan topaz is 950℃ for 11 h. The EPMA analysis showed that the Co concentration in the diffused sample varied from 0.001 wt% to 0.027 wt% while colorless topaz showed <0.001 wt%. The UV-Vis spectrum of Co diffused blue topaz gave three absorption peaks at 556, 588, and 627 nm corresponding to three spin-allowed electronic transitions of Co2+ ion in teterahedaral coordination. In case of Co diffused topaz, one additional new broader IR absorption peak was noticed around 6640 cm-1 presumably arising by optical transitions of 4A2 → 4T1 in Co2+ (4F).  Our results lead to the conclusion that, blue color of the Co diffused topaz is arising by spin-allowed electronic transitions of Co2+ ions in tetrahedral site of topaz matrix through substitution of Si4+ ions.

Published: March 2023

Silver is a well-known effective antibacterial and disinfectant material with relatively few side effects. Nanosilver derived from it, have strong antibacterial, antifungal and broad-spectrum antiviral properties. This study describes how the microwave synthesis durations of silver nanoparticles affect their shape, and the effect of the shapes of these nanoparticles on their antibacterial activity. The optical properties of the nanosilver were examined through UV-Vis absorption spectroscopy. The morphology of the grain was determined by transmission electron microscopy (TEM), and the crystallinity of the nanosilver was confirmed by X-ray diffraction (XRD). The antibacterial activities were assessed using bacterial pathogens Bacillus cereus and Bacillus megaterium, and were performed using the disk diffusion method. The obtained results show that (i) the shape and size of the nanosilver change when the microwave time is increased. They are of various sizes but almost all circular in shape when microwaved for 1.5 min, of larger sizes and different non-spherical geometric shapes after 3 min of microwave, and converted to nanowires after 5 min of microwave. (ii) Bacillus cereus and Bacillus megaterium were sensitive to all nanosilver but the antibacterial activity was more potent when the nanosilver possessed a defined shape than when they were silver nanowires.
Alfabetização de pessoas jovens e adultas e a vocação ontológica para o ser mais: o que nos diz o pensamento de Paulo Freire
Authors: Da Silva Oséias Lima , Portela Edinólia Lima
Published: March 2023

Trata-se de um estudo bibliográfico que caminha por uma abordagem de natureza qualitativa em que refletimos acerca da vocação ontológica para o “ser mais”, defendida por Paulo Freire. Para tanto, percorremos a perspectiva pedagógica de alfabetização para pessoas jovens e adultas, afirmando que essa premissa permite que os sujeitos sejam (re)criadores e que se (re)façam como seres de autonomia. O trabalho ancora-se à luz do pensamento de Freire (1979, 2009), Ana Freire (2014) e Hanh (2021). Entendemos que o decurso da alfabetização, afinado com o estatuto ontológico, propicia aos educandos/as condições que lhes oportunizarão reconhecerem-se como sujeitos e, assim, desvelarem a consciência no sentido de iniciarem o rompimento com as forças opressoras que concorrem para que não sejam “seres mais”. No entanto, para que esse ciclo se complete e a proposta se concretize como libertadora, é necessário que educandos/as e educadores/as alcancem a conscientização e a humanização, compreendendo, que o/a opressor/a também não é livre.

A poluição causada devido ao acúmulo de resíduos poliméricos convencionais, ou seja, provenientes do petróleo, é de grande preocupação para o meio ambiente e para o ser humano. Na busca da diminuição deste impacto ambiental, diversos estudos foram desenvolvidos e aplicados, utilizando os chamados plásticos de base biológica. Veículos automotivos são produzidos a partir de um quinto de seu peso utilizando plástico convencional, devido a isso, o presente trabalho apresentou por meio de revisão da literatura, os diferentes tipos de plásticos que possuem características biodegradáveis, como alternativa para o uso em veículos automotivos, a fim de aprofundar o assunto sobre o tema em questão. O interesse e a produção deste tipo de material, surge a partir de 1940. Anos mais tarde, aparecem os primeiros veículos automotivos que passaram a fazer uso de uma matriz de PLA (Ácido Polilático) de cana-de-açúcar e batata doce e uma matriz epóxi com a adição de juta para algumas peças dos veículos. Portanto, estes materiais já são uma realidade atualmente, e podem ser utilizados em veículos automotivos como substitutos dos polímeros convencionais.

A Lossless Audio Encryption Method based on Chebyshev Map
Authors: Demirtaş Mehmet
Published: March 2023

This paper presents a lossless and secure audio encryption method based on the chaotic Chebyshev map. Firstly, the input audio samples are preprocessed to obtain the integer and decimal parts. The integer parts are rescaled to the interval [0,255]. By iterating the Chebyshev map in the chaotic range using plaintext-dependent variables, the integer parts of the input audio sample are scrambled and then diffused. Finally, a post-processing operation is applied to the diffused audio samples. Keyspace and key sensitivity analysis, histogram analysis, the correlation between adjacent samples analysis, information entropy analysis, number of sample change rate analysis, and speed analysis results are presented. These security analysis results show that the proposed audio encryption method can be used in secure voice transmission applications.
Comparison of flexible and rigid annuloplasty rings in isolated mitral regurgitation
Authors: Altaş Özge
Published: March 2023

Objectives: The aim of this study was to examine the early and midterm results of various annuloplasty rings in terms of residual mitral regurgitation (MR) in patients undergoing mitral valve repair. Patients and methods: In the retrospective study, 298 patients (157 males, 141 females; mean age: 58.8±14.3 years; range, 16 to 82 years) underwent repair between September 2009 and April 2012. Two hundred eleven were assigned to the flexible ring group (Group 1), whereas 87 were included in the rigid ring group (Group 2). Mitral pathologies were divided into three subgroups: ischemic, degenerative, and rheumatic. Results: The causes of mitral pathology were ischemic in 36.2%, degenerative in 54.4%, and rheumatic in 9.4%. Concomitant surgical procedures were present in 87%. The follow-up period ranged from 2 days to 33 months, with a mean of 15.8±7.5 months. The 30-day mortality rate was 9.2% and 10.4% in Groups 1 and 2, respectively. There was a high rate of successful repair in the rigid group with 88.5% and acceptable rate of repair in the flexible group with 72%. Mitral regurgitation was significantly reduced after intervention regardless of the ring type (p<0.01). Significant improvement in NYHA class was observed in both groups. Recurrent regurgitation was detected in 27.9% of patients in Group 1 and 11.5% in Group 2. Recurrence occurred within three to nine months following the surgery. Reoperation rates for residual MR were 3.3% (n=7) vs. 1.1% (n=1) in Groups 1 and 2, respectively (p=0.293). Conclusion: Saddle-shaped rings provide a mechanical benefit through a low and uniform force distribution and improve repair durability compared to flat rings. As a result, the rigid ring had a significant advantage, particularly in degenerative and rheumatic subgroups, but there was a loss of superiority in late ischemic MR due to left ventricle remodeling.
Assessment of degree of endangerment of livestock breeds in India
Authors: SINGH P K , SHARMA ARJAVA
Published: March 2023

Complete national inventories, supported by periodic monitoring of trends and associated risks, are basic requirements for the effective management of farm animal genetic resources. Government of India conducted breed survey in 2013 to estimate breed-wise data for livestock belonging to different categories, breeds, age and sex groups. FAO has developed criteria for assessment of risk to the livestock breeds, which were used to assess the risk status of all the breeds of livestock species. Breed-wise populations of breeding males and females, overall population size, effective population size and rate of inbreeding were estimated. Cattle, sheep and pigs species were classified as indigenous purebreds, graded to indigenous breeds, indigenous non-descript, exotic purebreds and crossbreds to exotic breeds; while buffalo and goat species were classified under first three categories only. Proportion of indigenous purebreds of cattle, buffalo, sheep, goat and pig were found as 9.4, 17, 36.6, 27 and 3%, respectively of the total population of the species; whereas corresponding figures of graded to indigenous breeds and non-descript animals were estimated to be 10.5, 39.6, 18.9, 11.8 and 0% and 59.3, 43.4, 38.7, 61.2 and 73.1%, respectively. Large non-descript proportion of all the livestock species should be screened for identification, characterization and registration of new breeds. Exotic breeds and crossbreds to exotic breeds in cattle, sheep and pig were obtained as 0.7 and 20.1%; 0.7 and 5.1% and 2.3 and 21.6%, respectively of total population. The rate of inbreeding estimated for most of the breeds were well below 0.5% except for Mewati (1.193%), Pullikulam (0.72%) and Vechur (17.893%) cattle breeds and Chilika (0.731%) buffalo breed. Using the FAO criteria, Bargur and Siri cattle breeds and Attapadi goat breeds were categorized under vulnerable status of risk; Krishna Valley, Mewati, Pullikulam and Punganur cattle breeds, Chilika and Toda buffalo breeds and Karnah and Poonchi sheep breeds under endangered status of under risk and Vechur cattle under critical status of risk. All these breeds need immediate steps for rescue by using suitable conservation methodology. Breed-wise census should be continued in future so that trends in breed populations may also be estimated for fine tuning of risk assessment of breeds.

Published: March 2023

Starting from the innovation articulating principles as pillars for updating and educational excellence, it is pertinent to remark on the need to generate new ways to carry out the training processes to respond to students' interests in the digital age. In this line, one of the most pioneering innovations generated by the technological revolution has been the metaverse, a virtual world in which – out of digital devices – a great immersive experience and total interaction with its elements is generated in the user. Due to its short trajectory, the metaverse's potential in education is still waiting to be explored. This project aims to create an educational metaverse helping to develop the didactic contents of different curricular subjects to raise the teaching and learning process to a larger scale of immersion and innovation. For this purpose, a specific didactic methodology will be designed and implemented for training in the metaverse as well as the preparation and implementation of a competence-training program for creating and using virtual classrooms. This way, it will be possible to generate and transfer knowledge in the metaverse out of the improvement of the psychoeducational skills of students as well as to encourage inclusive education and the improvement of diversity care. The methodology this project will follow will be based on cooperative work and the principle of self-sufficiency for the efficient implementation of learning based on projects and problems to teach the didactic contents and achieve the learning objectives. All the above will start from a systematic strategy to follow up and evaluate the project's development and its impact.
The impact of new buildings on the city’s image
Authors: Koznarska Halyna , Didyk Volodymyr
Published: March 2023

The research examines the visual perception of new buildings and their impact on changing the overall image of the city. Particular attention is devoted to buildings that are visible from other parts of the city due to their greater height and hilly terrain and can complement the overall composition of the city or destroy it. The importance of exploring the analysis of visual connections between the designed object and the environment is substantiated. The purpose of the research is to explore the perception of the city environment as a set of multifaceted pictures and to identify the elements that have a significant impact on the development of the overall image of the city. To achieve this purpose, a research methodology was developed, which at each stage included general scientific methods and special ones. Before starting the work, field research was conducted on the compositional structure of individual cities, and several paintings were selected for more detailed research. A compositional analysis of the selected examples for planning was conducted using the graphical method. It is established that the city’s image is most influenced by the last plan, which, in most cases, is not considered when designing new buildings. As a result of the research, the results obtained were verified for compliance with the shape, style and proportions of the newly built objects with the surrounding buildings. A significant number of paintings were identified that do not correspond to the expected result from the standpoint of the observer. Thus, there is a discrepancy between the planned and the received image of the overall compositional and spatial structure. The reasons for this inconsistency in the combination of individual plans are identified, which in turn had adverse effects on the overall image of the city. In addition, the main factors that influence the development of individual paintings have been identified. The result of the research is defined tasks for pre-design research at the initial stage of designing new buildings. This approach will help minimise mistakes in the design of new buildings, particularly those that have visual connections with other parts of the city and have a significant impact on the overall image

Authors:   Le Quy Don Technical University, Phan Duc Nhan
Published: March 2023

This article presents an investigation of some plasticizers for composite solid propellants. The samples are prepared from the PVC plasticized by the DOP, DOA, and a mixture of DOP/DOA with ammonium perchlorate (AP) oxidizer, aluminum (Al) powder, and iron (III) oxide (Fe2O3). Mechanical properties and thermal characteristics of the samples were determined. The results show that the characteristics of the samples meet the requirements of composite solid propellant such as elastic modulus 176.7 ÷ 202.9 MPa, deformation 28 ÷ 45 %, ignition temperature 304.8 ÷ 308.4°C and thermal stability 0.081 ÷ 0.178 ml/g. The DOP plasticizer is a better effect on plasticization than the DOA. In addition, the sample from PVC/DOA causes more loss of weight and lower thermal stability than that from PVC/DOP.

Published: March 2023

Aim:
We developed the Patient-Engaged Health Technology Assessment strategy for survey-based goal collection from patients to yield patient-important outcomes suitable for use in multi-criteria decision analysis.
Methods:
Rheumatoid arthritis patients were recruited from online patient networks for proof-of-concept testing of goal collection and prioritization using a survey. A Project Steering Committee and Expert Panel rated the feasibility of scaling to larger samples.
Results:
Survey respondents (n = 47) completed the goal collection exercise. Finding effective treatments was rated by respondents as the most important goal, and reducing stiffness was rated as the least important. Feedback from our steering committee and expert panel support the approach's feasibility for goal identification and ranking.
Conclusion:
Goals relevant for treatment evaluation can be identified and rated for importance by patients to permit wide input from patients with lived experience of disease.
Conducting Socially Aware and Value Oriented Investigations: a Case Study on the Violence Against Children and Adolescents

Published: March 2023

In challenging social contexts of technology design, such as those involving fighting the violence against children and adolescents, the consideration of human values is critical, as they influence people's social and cultural lives. Considering values when understanding a social problem is not a trivial activity due to the difficulty of working with abstract concepts, the complexity of people's lives, and the lack of artifacts and recommendations to support designers in this task. Drawing on the Socially Aware Design approach, this paper describes the use of value-oriented artifacts to understand the problem and to identify requirements for the design of a computational solution in this context. As a result, the problem of violence against children is characterized in a socially-aware manner: 58 stakeholders were identified in the problem domain, which led to an analysis of 60 challenges of the violence impact and of 31 proposals of solutions were mapped to face these challenges. Stakeholder’s values in the fight against violence context were identified, which enabled the identification of 43 value-oriented requirements for potential technological solutions for the context.

Published: March 2023

Data are the foundation of the digital economy, but various challenges regarding managing data assets still exist. One approach to solving these challenges is applying the data-sharing economy principles. Many companies are, however, unsure of the factors that need to be developed to enter a data ecosystem successfully with other, partially competing organizations. Based on qualitative data gathered from an interview study, this research paper applies a framework for organizational readiness factors to data ecosystems. Legal foundation, top management support, and stakeholder involvement in data ecosystems are the main factors highlighted by the study. Furthermore, our empirical results confirmed our preliminary findings from a structured literature review and extend the given research framework.

NESTING PECULIARITIES AND INTERLAY VARIABILITY OF THE STERNIDAE FAMILY BIRDS’ EGGS IN THE PRIPYAT RIVER MIDDLE STRECH FLOODPLAN
Authors: Nazarchuk Olga
Published: March 2023

Purpose: to analyze the nesting features of birds of the Sternidae family living in the floodplain meadow of the Pripyat River.
Methodology. For research, the route method was used, in which bird nests were identified during direct examination of the territory of the floodplain meadow. Hard-to-reach areas of the meadow were surveyed from a boat. To assess the morphological parameters of the eggs of birds of the Sternidae family, the eggs were measured using a caliper. The length (L) and diameter of the eggs (B) were measured. Based on the measurements, the index of intra-laying variability (iv) was determined. During the study period, 245 eggs of birds of the Sternidae family were measured, of which 88 eggs were in the Common tern, 60 eggs in the Little tern, 51 eggs in the White-winged tern and 46 eggs in the Whiskered tern.
Scientific novelty. It has been established that the formation of multispecies colonies of birds of the Sternidae family makes it possible to qualitatively use territories favorable for nesting and provides protection of nests from raptors to accompanying bird species. The smallest intra-laying variability of the studied egg parameters was found in the common and barnacle tern, which is an indicator of the birds’ adaptability to nesting conditions.
Conclusions. The nesting of White-winged black and Whiskered tern is directly dependent on floodwater level. A gradual decrease in the level of floodwaters leads to the drying up of the floodplain meadow and the impossibility of building nests, since these species build nests on aquatic plants or floating bogs.
Nesting of Little and Common tern is limited by biotic factors, such as predation by Corvidae birds and other animals, as well as anthropogenic factors - people resting on the shore, fishermen and locals visiting the meadow, which in turn creates a disturbance factor for the birds.
Among the bird species considered, the maximum value of the index of intra-variability of eggs laying in egg diameter (iv) was found for White-winged black tern (iv = 4.10 ± 0.52). The minimum value of this index is observed in Whiskered tern (iv = 3.41 ± 0.39). It should be noted that differences in this index among Common tern are less pronounced than among Marsh tern
The maximum value of the index of intra-variability of eggs laying (iv) was found for Little Tern (iv = 5.42 ± 0.65). The minimum value of this indicator was found in Common tern (iv = 3.90 ± 0.44). For Marsh tern (Whiskered and White-winged black tern), the value of the index of intra-variability of eggs laying length (iv) does not differ significantly.
