Особенности реконструкций крупных театральных зданий
Authors: Анисимов А.В.
Published: June 2021

Статья (доклад) составлена на основании собственного опыта автора в проектировании и реализации реконструкции Театра на Таганке и Звездного театра Планетария в Москве, а также на результатах изучения отечественного и мирового опыта реконструкций зрелищных сооружений. В работе освещены цели и задачи реконструкций крупных театров, трудности их выполнения и ряд важнейших выводов. Реконструкция театрально-зрелищного сооружения – явление неизбежное, периодически повторяющееся, имеющее две основные причины:  совершенствование существующего здания и  восстановление сооружения в результате износа и после техногенных катастроф или войн. Основное противоречие проектных работ при реконструкции –стремление к сохранению исторического облика сооружения и необходимости его технологического совершенствования с использованием достижений технического прогресса. Автор определяет два типа реконструкций: локальную и комплексную, делая вывод, наиболее эффективным способом обновления здания следует считать комплексную реконструкцию, которая в разной степени охватывает все виды работ ( архитектурнопланировочную, конструктивную, технологическую, инженерные сети, реставрацию охраняемого наследия). В качестве иллюстративных примеров приводится рассказ о разных типах реконструкций Большого театра в Москве и Мариинского театра в Петербурге.

Authors: Tung Ho-Jui , Yeh Ming-Chin , Ford Randall , Shah Gulzar
Published: June 2021

Introduction: Higher personal mastery is associated with better physical functioning, wellbeing, and longevity among older populations. However, few studies have focused on whether personal mastery is protective against mortality among older adults living with diabetes over time.
Methods: A total of 1,779 participants were identified from an off-year survey of the Health and Retirement Study. Proportional Hazard Models were used to evaluate the significance of selected variables in predicting the survival of participants over a 13-year period.
Results: A substantial proportion (46.7%) of the diabetic patients had survived by the end of 2016. Adults with lower mastery scores were more likely to die (Hazard Ratio = .94, p < .001). Gender differences in the association patterns between personal mastery and survival were identified. Personal mastery had an independent health-protective effect on the survival of diabetes patients over the study period. With lower educational attainment, the foreign-born female diabetics scored higher in personal mastery measure when compared to their male counterparts. In the face of more severe diabetes comorbidity, foreign-born female diabetics also  outlived their male counterparts over the study period.
Conclusion: As a crucial psychological resource and a modifiable factor, personal mastery holds a potential for improving the health status among lower SES groups of older adults. Further investigations into the identified gender difference could be applied to break the cycle of poor health among lower Socio-Economic Status groups of older adults.

Authors: Pengpid Supa , Peltzer Karl
Published: June 2021

Introduction: Aging may increase physical or functional limitations, and India has a rapidly aging population. This study aimed to assess the prevalence and correlates of difficulties with Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) among older adults in India.
Methods: The cross-sectional sample consisted of 31,477 individuals (≥ 60 years) from the Longitudinal Aging Study in India, Wave 1 in 2017-2019. Functional disability was measured with 6 items of ADL and 7 items of IADL.
Results: The prevalence of at least one ADL difficulty was 23.8%, at least one IADL difficulty was 48.4%, and at least one ADL/IADL difficulty was 52.0% (43.2% among men, and 60.0% among women). In the adjusted logistic regression analysis, older age, and food insecurity were positively and male sex and having a health insurance were negatively associated with both ADL and IADL difficulty. No formal education was positively and urban residence and married were negatively associated with IADL difficulty. Poor or faith self-rated health status, chronic conditions, insomnia symptoms, major depressive disorder, physical pain, poor distant vision, poor near vision and poor word recall were positively associated with both ADL and IADL difficulty. Body underweight and hearing or ear problem increased the odds for IADL difficulty. In univariate analysis, vigorous physical activity and higher social network were protective against both ADL and IADL difficulty.
Conclusion: Almost one in four older adults in India had ADL difficulty and almost half had IADL difficulty and several associated factors were identified that can be targeted in interventions.

Published: June 2021

Introduction: Healthcare- Associated Infections (HAI) are known to be one of the most important health issues in developed and developing countries. The most common infections include central line-associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumonia and surgical site infection. The aim of this study was to investigate the incidence of nosocomial infections in the elderly patients.
Methods: In this cross-sectional study, 1279 patients were 60 years of age or older. Patients who had been admitted for more than 48 hours in the hospital and had no signs of infection at the time of admission, were entered into the study. It was evaluated four most common HAI, according to CDC include bacteremia, central line-associated blood stream infections, urinary tract infections, and ventilator-associated pneumonia. Infections may also occur at surgery sites, known as surgical site infections. The Chi-square and T- test or analysis of variance was used for data analysis.
Results: Of the total patients, 93 (7.3%) developed HAI at duration admission. The highest rate of infection was bacteremia, which was 48.4 % and then urinary tract infection 21.5%. The prevalence of HAI among patients with cardiovascular diseases was relatively higher than underlying diseases. The frequency of length of hospital stay was significant in patients > 7 days with 68.8% in the HAI group.
Conclusion: Our findings showed that patients with cardiovascular, renal and pulmonary disease are more susceptible to HAIs. Due to the increased length of hospital stay increases the risk of infection, it is recommended to discharge patients as soon as possible.

Published: June 2021

Introduction: Medical tourism is a fast-growing industry that has provided special opportunities for international organizations to achieve a competitive advantage. This research has been conducted to recognize and prioritize the factors affecting the admission of medical centers into the medical tourism market in Iran.
Methods: The combined study was conducted in two qualitative stages and hierarchical analysis in governmental and non-governmental centers related to medical tourism on 15 experts and specialists in the qualitative stage and 25 people in a quantitative stage. The interview guide was used to collect data in the qualitative stage and the pairwise comparison questionnaire was used in the hierarchical analysis stage. Qualitative phase results were analyzed by conceptual framework method and quantitative phase results were analyzed by AHP method applying 11 Expert Choice software.
Results: 41 sub-themes were identified in the qualitative stage, which were categorized into six groups: service quality, infrastructure, human, information, economic and political. The highest weight or priority was related to the diversity and quality of services and the lowest weight or priority was associated with the field of information and marketing among the six factors based on the Analytical Hierarchy process (AHP) method.
Conclusion: The most significant factor for medical centers to join the health tourism market is to focus on the quality of provided services based on the results. It is recommended that medical centers provide all services from the time of admission to follow-up after discharge in the context of intelligent and web-based systems in order to strengthen the quality of services, in addition to standardize departments and treatment processes according to international standards.

Background: A few studies have reviewed and revised ICU admission criteria based on specific circumstances and local conditions. The aim was to develop ICU admission criteria and compare the cost, mortality, and length of stay among identified admission priorities.
Methods: This was a cross-sectional study conducted in an intensive care unit of a training hospital in Qazvin, Iran. The study was conducted among 127 patients admitted to ICU from July to September 2019. The data collection tool was a self-designed checklist, which included items regarding patients' clinical data and their billing, type of diagnosis, level of consciousness at the time of hospitalization based on GCS scale or Glasgow Coma Scale, length of stay, and patient status at the time of discharge. Descriptive statistical tests were used to describe study variables, and in order to determine the relationship between study variables, ANOVA and Chi-square test were used.
Results: A set of criteria were designed to prioritize patient admissions in ICU. Based on the defined criteria, patients were categorized into four groups based on patient's stability, hemodynamic, and respiration. Study findings revealed that a significant percentage of patients were admitted to the ward while in the second and third priorities of hospitalization (26.8 % and 32.3 %, respectively). There was a statistically significant difference in the four groups in terms of patients' age, total cost, and insurance share of the total cost (P-value < 0.05).
Conclusion: Study results emphasize the necessity to classify patients based on defined criteria to efficiently use available resources.

Published: June 2021

Introduction: Fungal aerosols cause life-threatening infections in patients hospitalized in critical wards. Antiseptics and disinfectants have broad-spectrum antimicrobial activity against the living tissue and inert surfaces microorganisms; hence, they have an essential role in controlling and preventing nosocomial infections. This study aimed to evaluate in vitro antifungal activity of benzalkonium chloride (BAC), chlorhexidine digluconate (CHX), and sodium hypochlorite (SH) against isolated fungal aerosols from the hospital environment.
Materials and Methods: The susceptibility tests were performed on fungal aerosols isolated from various wards of Children’s Medical Center, based on broth microdilution antifungal susceptibility testing of filamentous fungi approved by the Clinical and Laboratory Standards Institute (CLSI) M38-A2 document. The isolates included Aspergillus (Aspergillus flavus (n = 14), Aspergillus niger complex (n = 12), Penicillium spp. (n = 14), and Cladosporium spp. (n = 14).
Results: The geometric means (GM) of the Minimum Inhibitory Concentrations (MICs) of the biocides across all isolates were as follows: BAC, 3.56 µg/ml, CHX, 9.45 µg/ml, and SH, 810.35 µg/ml. The highest range of MICs was found for SH (50-12800 µg/ml), while the lowest range was for BAC (1-16 µg/ml) against all fungal isolates. Generally, BAC showed the highest in vitro activity among disinfectants tested. The lowest MIC50 and MIC90 values were 4 and 8 µg/ml for BAC, followed by 16 and 32 µg/ml for CHX, and 800 and 6400 µg/ml for SH, respectively.
Conclusion: The findings showed that BAC was an effective disinfectant, which can  prevent resistant species and fungal pathogens and be used an alternative to other disinfectants and antiseptics.

Background: Refugees are vulnerable to tuberculosis (TB) infection. Tracking of program performance is needed to improve TB care and prevention. The objective of this study was to assess the trends of TB treatment outcomes of notified cases in three refugee camps in Sudan from 2014 to 2017.
Methods: This study was a historical cohort study. Sex, age, type of TB, TB patient category, and treatment outcome of all TB cases registered in three refugee camps (Al Kashafa, Shagarab, Wadsherify) from January 1, 2014 to December 31, 2017 were collected from the TB register. Multivariable logistic regression was performed to explore factors for unsuccessful TB treatment.
Results: A total of 710 TB cases of which 53.4% were men, 22.1% children (<15 years), and 36.2% extrapulmonary TB (EPTB) were registered. Overall, the TB treatment success rate was 75.7% with a declining trend from 86.2% in 2015 to 63.5% in 2017. On average, 11.4% were lost to follow-up (LTFU), 6.6% died, 5.9% were not evaluated, and in 0.3% the treatment failed. Being 15–24 years old and having EPTB were significantly associated with unsuccessful treatment outcome.
Conclusion: The treatment success rate in the refugee camp in 2017 (63.5%) was far lower than the national treatment success rate (78%) and the End TB global target (≥90%) that needs to be improved. LTFU, died, and not evaluated outcomes were high which indicated the necessity to improve the TB treatment program.

Published: June 2021

Background: A year after the COVID-19 pandemic spread around the world, the pandemic is still affecting healthcare systems with an increasing number of infected healthcare workers. Such a unique situation may often result in emotional turmoil, anxiety, depression, and fear, which could lead to resignation and burnout. The study intended to assess the feelings of nurses toward the COVID-19 outbreak; ascertain the factors that cause stress; and determine their coping strategies and factors contributing to coping.
Methods: A descriptive cross-sectional design was utilized to recruit 313 nurses working in the Ministry of Health (Saudi Arabia) hospitals that accommodate COVID-19 patients. The study instrument was adapted and modified from the ”MERS-CoV Staff Questionnaire” and the Brief COPE.
Results: The results showed that female, married, those with a bachelor’s degree, and aged 25–34 years had higher significant coping strategies. On the other hand, Filipino nurses assigned in the Outpatient Department and COVID-19 Isolation Ward had more negative feelings and encountered several factors causing stress but were coping in a better way than others.
Conclusion: Nurses’ commitment to their profession appears to be an intrinsic motivation to continue caring for COVID-19 patients despite the risk of infection. Comfort with religion, spiritual beliefs, and the presence of a support system were the coping strategies used by nurses to ameliorate the stress and negative feelings during the COVID-19 outbreak.

Published: June 2021

The roles of novel peptides such as peroxisome proliferator-activated receptor gamma coactivator 1- alpha (PGC1-α), irisin, brain-derived neurotrophic factor (BDNF), galanin and alarin in Alzheimer's disease (AD) are not fully known. It was aimed to plasma levels of the novel peptides that may affect the pathophysiology of AD were examined. This study was conducted as a cross-sectional. The study consisted of two groups, including 45 newly diagnosed individuals with AD and 45 healthy individuals. The peptide levels in plasma samples collected from the groups were measured by the ELISA method. The mean plasma peptide levels and age differences, between the groups, and the correlations between them were analyzed by the statistically. The means ages of both groups were over 65 years old. When plasma PGC1-α, irisin, BDNF, galanin, and alarin levels between the groups were examined, decreases were found in the group with AD (3.56±0.79ng/mL, 16.33±4.07ng/mL, 3.36±1.47ng/mL, 13.93±4.24ng/L, 31.99±11.89pg/mL, respectively) compared to the control group (4.23±1.31ng/mL, 22.19±9.61ng/mL, 4.58±2.10ng/mL, 14.4±9.01ng/L, 54.93±15.80pg/mL, respectively). In the negative correlations observed between age and plasma peptide levels. Significant positive correlations were observed between plasma PGC1-α levels and irisin, alarin, and BDNF, and the significant positive correlations were also observed between plasma BDNF levels and irisin and alarin. As far as we know, the study is the first report in which the peptides mentioned in AD were examined together. We consider that more detailed studies are needed to shed light on the roles and mechanisms of these peptides in AD.

The present study focuses on the effect of experimental parameters (pH, temperature, gel mass, metal concentration, contact time) on the performance of lead adsorption by polyacrylamide hydrogels. The results obtained showed that the retention of Pb2+ ions is closely linked to these parameters. The adsorbent gels equilibrate with the metal solution after 180 minutes, and the maximum adsorption capacity is 442.31 mg/g. In addition, the adsorption obeys the pseudo-second-order kinetics and Langmuir isotherm. Desorption of the micropollutant retained by the hydrogel was also studied using 0.1 M of HCl solution. The desorption was rapid, and the efficiency exceeded 90% after a contact time of 90 minutes.

A área de estudo está localizada na praia de Massarandupió (12°19´12"S; 37°50´15"W), município de Entre Rios, Bahia. Para amostragem, foram alocadas 50 parcelas de 1m2 ao longo da área e calculados os dados fitossociológico, o índice de diversidade Shannon (H´), equabilidade de Pielou (J´) e riqueza total das espécies. Foram incluídos todos os indivíduos com hábito herbáceo e subarbustivo, sendo coletados 3.804 indivíduos, pertencentes a 12 espécies, distribuídas em nove famílias. As espécies Rhynchospora riparia, Chamaecrista ramosa, Eriocaulon sp. e Comolia ovalifolia apresentaram os maiores valores de importância (VI's). Os valores de (H') e (J') quando calculados com a cobertura vegetal foram, respectivamente, H'c = 1,453 nas/m² e J'c = 0,585. As dunas de Massarandupió apresentaram uma vegetação com ervas e subarbustos distribuídos em moitas. As famílias Fabaceae, Cyperaceae e Poaceae destacaram-se por apresentarem maior número de espécies, sendo predominantes em ambientes de praias, por se adaptarem facilmente em ambientes adversos assim como seu importante papel ecológico, auxiliando na fixação das dunas.ABSTRACTThis study aimed to carry out a phytosociological analysis of the herbaceous and sub-shrub composition of the dunes on the northern coast of Bahia, with the purpose of knowing and characterizing the herbaceous-subshrub community.

ABSTRACTCongenital deformities are relatively common in rays and sharks. The present study aimed to describe a case of bicephaly in an R. lalandii embryo. Through radiographic images and evaluation of the external and internal condition of the embryo in comparison with a young of the year with no deformities of the same species, it was possible to characterize the abnormality observed. Such data are important to determine the frequency and types of anomalies observed in elasmobranchs, thusallowing greater knowledge about developmental abnormalities in the group and their possible causes. RESUMODeformidades congênitas são relativamente comuns em raias e tubarões. O presente estudo teve como objetivo descrever um caso de bicefalia em um embrião de R. lalandii. Através de imagens radiográficas e avaliação da condição externa e interna do embrião em comparação com um jovem do ano sem deformidades da mesma espécie, foi possível caracterizar a anormalidadeobservada. Tais dados são importantes para determinar a frequência e tipos de anomalias observadas em elasmobrânquios, permitindo assim o maior conhecimento sobre as anormalidades de desenvolvimento no grupo e suas possíveis causas.Palavras-chave: Malformação; Tubarão; Espécie endêmica; Morfologia.

Muitos corpos hídricos têm sido degradados devido à interferência humana. A poluição causada pelas atividades antrópicas vem comprometendo a qualidade da água e promovendo eventos de eutrofização, afetando toda estrutura trófica do ambiente, podendo assim acarretar na proliferação de cianobactérias tóxicas. Nesse sentido, o conhecimento sobre esses organismos é de grande importância, principalmente em corpos hídricos com usos múltiplos. Esta pesquisa representa uma revisão de trabalhos publicados envolvendo qualidade ambiental e ecolotoxicologia aquática, tendo como foco estudos relacionados às cianobactérias e cianotoxinas. Para o trabalho foram analisados livros textos e artigos publicados entre 2010 e 2020 em periódicos nacionais e internacionais. Na literatura publicada nos últimos anos são apresentadas as principais metodologias envolvidas na detecção e remoção de cianotoxinas, além de bioensaios ecotoxicológicos. Fica evidente a importância do tratamento de efluentes e controle das fontes de poluição difusas e pontuais no ecossistema promovendo a melhoria da qualidade da água e controle de cianobactérias.ABSTRACTCyanobacteria play an important role among producers in aquatic ecosystems, however when associated with eutrophication they become an ecological and public health problem. The problem involving cyanobacteria is the blooming of potentially toxic strains. The present work aims to present and discuss the problems related to the proliferation of cyanobacteria in limnological environments, and its consequences for dynamics in the environment and effects on environmental health. In this sense, knowledge about these organisms is of great importance, especially in water bodies with multiple uses. This research represents a review of published works involving environmental quality and aquatic ecotoxicology, focusing on studies related to cyanobacteria and cyanotoxins. For the present work, textbooks and articles published between 2010 and 2020 in national and internationaljournals were analyzed. In the literature published in recent years, the main methodologies involved in the detection and removal of cyanotoxins are presented, in addition to ecotoxicological bioassays. The study of cyanobacteria and their metabolites comprises an area of interest that reaches a greater dimension when impacts on the quality of water supply are evident, thus the importance of treating effluents and controlling pollution sources in the ecosystem is evident, promoting improvement and maintenance the quality of the water bodies.
Peru's Regional Growth and Convergence in 1979-2017: An Empirical Spatial Panel Data Analysis
Authors: Palomino Juan , Rodríguez Gabriel
Published: June 2021

Este artículo analiza el proceso de convergencia espacial del crecimiento en las 24 regiones del Perú durante el período 1979-2017. Realizamos un análisis exploratorio de datos espaciales con estadísticas globales y locales, como Moran I, para proporcionar evidencia empírica de las dependencias espaciales en el PIB per cápita regional. . Luego, estimamos la ecuación de convergencia utilizando modelos de panel espacial que controlan la heterogeneidad espacial y la interdependencia espacial, así como otras características económicas estructurales a nivel regional. Los resultados empíricos muestran que la convergencia espacial es una conclusión muy confiable durante este período y demuestran que los derrames regionales del PIB per cápita espacial juegan un papel esencial en la determinación del crecimiento a nivel local. Además, se prefiere el modelo Spatial Durbin en la formación de cuatro grupos de convergencia. El primer clúster es muy productivo y dinámico; el segundo conglomerado está compuesto por regiones selváticas y de productividad negativa; el tercer conglomerado está formado por regiones moderadamente productivas y costeras; y el cuarto grupo está compuesto por regiones estancadas y montañosas. Por último, estos resultados pueden ser fundamentales para dar un mayor enfoque a las políticas gubernamentales a largo plazo dirigidas a las regiones pobres y estancadas.
Single Versus Combined Forecasting: The Case Of Wind Run Data

Published: June 2021

This article compared single to combined forecasts of wind run using artificial neural networks, decomposition, Holt-Winters’ and SARIMA models. The artificial neural networks utilized the feedback framework while decomposition and Holt-Winters’ approaches utilized their multiplicative versions. Holt-Winters’ performed best of single models but ranked fourth, of all fifteen models (single and combined). The combination of decomposition and Holt-Winters’ models ranked best of all two-model combinations and second of all models. Combination of decomposition, Holt-Winters’ and SARIMA performed best of three-model combinations and ranked first, of all models. The only combination of four models ranked third of all models. The accuracy of single forecast should not be underestimated as a single model (Holt-Winters’) outperformed eleven combined models. It is therefore, evident that inclusion of additional model forecast does not necessarily improve combined forecast accuracy. In any modeling situation, single and combined forecasts should be allowed to compete.

UNDERSTANDING OUTCOMES OF THE PANDEMIC: SAFETY ETHICS
Authors: Filippov A. V. , Donika A. D. , Ostrovsky A. M.
Published: June 2021

Summing up the interim results in the fight against the COVID-19 pandemic determines a multidisciplinary approach to studying the problem of security for all spheres of society. The analysis of the priority of scientific publications carried out on the platform of the information resource CyberLeninka showed that the main interest of researchers is medical and information security. Taking into account the tendency for legal norms to lag behind ethical ones, and the specifics of the legal support of these spheres of social life, a working hypothesis was developed based on the assumption that the explication of ethical challenges during the COVID-19 pandemic will determine the strategy of social policy in these priority areas. Quantitative and qualitative sociological methods (content analysis, case study, survey) were used in the work. Fragments of sociological research carried out in collaboration based on the Volgograd and Gomel State Medical Universities are used. The results obtained demonstrate ethical deformations in the medical and, in general, in the social sphere. In the context of the pandemic, the problem of the vulnerability of socially unprotected groups has become more acute. The basic moral tenets of the ethics of care are violated in relation to patients with severe concomitant diseases and patients with limited mobility. The extreme conditions which the national health care system found itself began to be perceived in the professional group of medical specialists as "extenuating circumstances" allowing, in conditions of survival, to neglect not only medical ethics, but also the law. These tendencies are reflected in the minds of future doctors, which requires strengthening the positions of the humanitarian block of disciplines in the curricula of professional education. The tendencies noted have an international nature, which determines the possible implementation of the approaches developed in the process of international collaboration into the practice of humanitarian national professional education.
