Published: October 2022

Background and purpose: During the first COVID-19 lockdown elective surgery was greatly reduced. Prioritization of patients with greater need and expected benefit in terms of quality of life was advised. The lockdown also potentially affected follow-up outcomes. Therefore, our study compared patient-reported outcome measures (PROMs) retrieved during the lockdown of Dutch primary total hip and knee arthroplasty (THA, TKA) patients with previous years.Patients and methods: We performed cross-sectional analyses using national data from the Dutch Orthopaedic Registry (LROI). All primary elective THA and TKA patients with preoperative or postoperative PROMs (EQ-5D-3L index, OHS/OKS) during the first COVID-19 lockdown between March and July 15, 2020 were included. Patients with PROMs during the same months in 2018 plus 2019 were used as control. Finally, 33,453 THA and 27,335 TKA patients were included. Patient characteristics were compared during versus before the lockdown. Subsequently, the lockdown effect on PROMs scores was analyzed with multivariable linear regression.Results: During the COVID-19 lockdown, THA and TKA patients had a lower age and BMI preoperatively, and more often had surgery in private clinics. Both preoperative PROMs in THA patients, but not in TKA patients, were worse (EQ-5D: Adjusted mean difference (AMD) –0.021, p < 0.001) during the lockdown compared with prior years. Both postoperative PROMs in THA and TKA patients were better during the lockdown (12-month EQ-5D in THA: AMD 0.010, p = 0.003; and in TKA: AMD 0.013, p < 0.001).Interpretation: During the COVID-19 lockdown, THA patients had slightly worse preoperative PROMs, suggesting selection of patients with greater urgency. Postoperative PROMs in both THA and TKA patients differed minimally. Overall, the observed differences were likely not clinically relevant.

Authors: Cho Soo Ick , Lee Hanjae , Cho Soyun
Published: October 2022

The association between rosacea and skin cancer remains inconclusive, with conflicting reports. The aim of this nationwide population-based cohort study was to determine the risk of skin cancer in patients with rosacea. A rosacea cohort (n = 11,420) was formulated and evaluated from 2010 to 2019. The incidence rate ratios of actinic keratosis, cutaneous melanoma, keratinocyte carcinoma and gastric, colorectal, and liver cancer were analysed in comparison with a matched control group, and multivariable stratified Cox proportional hazards model analysis was performed. The risk of actinic keratosis and keratinocyte carcinoma was increased in the rosacea group compared with the control group, with adjusted hazard ratios of 6.05 (95% confidence interval 3.63–10.09) and 2.66 (1.53–4.61), respectively. The risk of cutaneous melanoma and gastric, colorectal and liver cancer was not increased, with adjusted hazard ratios of 1.69 (0.25–11.37), 0.81 (0.59–1.10), 0.91 (0.69–1.18) and 1.32 (0.89–1.95), respectively. These results reveal an increased risk of actinic keratosis and keratinocyte carcinoma in patients with rosacea.

Venous leg ulcers represent a clinical challenge and impair the quality of life of patients. This study examines impaired wound healing in venous leg ulcers at the molecular level. Protein expression patterns for biomarkers were analysed in venous leg ulcer wound fluids from 57 patients treated with a protease-modulating polyacrylate wound dressing for 12 weeks, and compared with exudates from 10 acute split-thickness wounds. Wound healing improved in the venous leg ulcer wounds: 61.4% of the 57 patients with venous leg ulcer achieved a relative wound area reduction of ≥ 40%, and 50.9% of the total 57 patients achieved a relative wound area reduction of ≥ 60%. Within the first 14 days, abundances of S100A8, S100A9, neutrophil elastase, matrix metalloproteinase-2, and fibronectin in venous leg ulcer exudates decreased significantly and remained stable, yet higher than in acute wounds. Interleukin-1β, tumour necrosis factor alpha, and matrix metalloproteinase-9 abundance ranges were similar in venous leg ulcers and acute wound fluids. Collagen (I) α1 abundance was higher in venous leg ulcer wound fluids and was not significantly regulated. Overall, significant biomarker changes occurred in the first 14 days before a clinically robust healing response in the venous leg ulcer cohort.

В статье рассмотрен вопрос влияния жизненного сценария на удовлетворенность жизнью. Основное внимание в работе акцентируется на проявление именно синдрома отложенной жизни, как на явление, включающие себя не только соответствующие сценарное поведение, но и сопутствующий ему невроз. Актуальность работы обуславливается широким распространением обозреваемого феномена. Новизна работы заключается в том, что впервые затрагивается вопрос возможности влияния синдрома отложенной жизни на субъективное благополучие. Во Введении автор приводит актуальность исследования, которая продиктована повышенным интересом общества и каждой личности, в частности, к вопросу о том, что может влиять на удовлетворенность жизнью. Еще одним аспектом актуальности исследования является распространенность синдрома отложенной жизни. Приводится аналитический обзор различных подходов к вопросам удовлетворенности жизнью, синдрома отложенной жизни, жизненным сценариям. Для исследования было проанкетировано 100 человек в возрасте от 18 до 65 лет. В разделе «Методы» обозначены основные способы анализа как теоретических, так и эмпирических данных. Результаты исследования показывают связи между синдромом отложенной жизни и уровнем жизненной удовлетворенности. В разделе «Обсуждение результатов» автор отмечает, что удовлетворенность жизнью зачастую связана с достижением существующего у человека эталона жизни. Основным отличительным признаком синдрома отложенной жизни является существование переломного момента, который наступает при достижение главной цели, после которого должна начаться настоящая и счастливая жизнь. Соответственно люди, проживающие сценарий, не могут ощущать полную удовлетворенность жизнью, в силу большого расхождения между желаемым и действительным. В Заключении автор приходит к выводу о том, что наличие синдрома отложенной жизни отрицательно влияет на удовлетворенность жизнью.

Published: October 2022

Large thermal power plants (TPP) located within the boundaries of urban areas usually use diesel or black oil as a reserve fuel (RF). In some cases, coal is also used. That has a negative impact on the natural environment of the city. In accordance with this, the new procedure for the creation and use of fuel reserves by thermal power plants provides as an option the use of liquefied natural gas (LNG) as a reserve and emergency fuel. Replacing RF (reserve fuel) with natural gas will, to some extent, reduce the load on the environment and reduce the area occupied by reserve fuel facilities (RFF). Since the construction and maintenance of RFFs at boiler plants and thermal power plants (TPP) requires significant capital investments and operating costs, the transition to LNG, which has its own specifics, requires additional analysis, given in this article, which evaluates the requirements for LNG volumes, places of production, storage and delivery of LNG to the TPP. The potential benefits of RF's transition to LNG have been assessed and challenges requiring further research have been formulated.

Authors:   Orenburg State University, Puzakov A. V.
Published: October 2022

The study of the factors affecting the internal resistance of automobile storage batteries will reduce the negative consequences of sudden failures. Despite the large number of publications on this subject, there are almost no studies in which the change of structural and diagnostic parameters is investigated by means of physical modeling of batteries` characteristic failures. The purpose of this work is to analyze the change in the internal resistance of automobile storage batteries based on data processing in the mode of starter discharge. As a result of the study, it was experimentally established that the value of the internal resistance of automobile storage batteries is affected by the electrolyte temperature, operating time, the degree of charging and the degree of serviceability. The author proposes a mathematical model of the battery internal resistance taking into account the change of operation factors. The practical use of this model will allow assessing the technical condition of the automobile storage battery on board the vehicle.

Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Belyy G. I. , Garipov A. I. ,   Saint Petersburg State University of Architecture and Civil Engineering
Published: October 2022

The article proposes using a technique of calculation the post-limit (residual) bearing capacity of steel frame elements relating to the strength check, in general case of loading, taking into consideration the post-critical behavior of plates making up the frame element and large plastic strain overflowing into the self-hardening stage. The solution is made by the “reverse” method in dimensionless parameters with increments of the strain of the most stressed fiber, which allows reducing by orders of magnitude the calculation time compared to existing methods. Herewith, the results of post-critical resistance of plates were used, which were obtained considering geometric imperfections and initial stresses under deformations in the form of limit relative slenderness of working parts of plates, that were approximated in form of functions for convenience and extrapolated to the values . The graphs showing how the bearing capacity reduction coefficient depends on the value of the normalized strain of the most stressed fiber for some of the cross-sections most widely used in construction practice are presented.

Published: October 2022

The paper studies the effect of the shape of the internal transverse defect on the fatigue crack resistance of the beam. The beam on a solid elastic foundation with a cross-section in the form of an unequal I-beam is subjected to cyclic bending by concentrated force. Various schematizations of the defect are considered, namely, a crack of circular shape, elliptical, oval, and oval of the fourth degree shape. A comparative analysis of stress intensity factors is performed. The dependence of the permissible number of loading cycles on the applied force for circular and oval cracks has been established, taking into account the boundaries of the body. The proposed calculation scheme is used to estimate the residual life of railway rails.

An Overview of Job Satisfaction of Emergency Healthcare Providers In Northern Cyprus
Authors: Aylanç Daghan , Aslay Semra
Published: October 2022

Introduction: Emergency calls are a challenging triangle that requires quick assessment, immediate action, and correct decision-making. The appropriate work environment and conditions of emergency healthcare workers result in this triangle's flawless functioning. This study aims to evaluate and overview the job satisfaction of the personnel working in emergency healthcare in Northern Cyprus.
Methods: This descriptive study was conducted to evaluate the job satisfaction of the personnel working in emergency healthcare in Northern Cyprus. This research involved nurses, paramedics, and EMTs, who intervene in an emergency call. The participants' job satisfaction was evaluated by the scale developed by Güneri (2011). The scale score range was 47-235. A high score was considered as increased job satisfaction.
Results: 132 personnel who work in emergency healthcare in Northern Cyprus participated in this study. 31.82% were aged between 36 and 49 years, 81.6 % were women, and 42.42% were undergraduates. 31.6% had worked for more than ten years. 39.39% (52) declared that they had occupational disease/accidents. 43.18% said they had received training more than two years ago. The participants' mean job satisfaction score was moderate (143.59 ± 26.86). Job satisfaction was higher in emergency call center personnel, high school graduates, and head nurses, working 40-50 hours a week, with seniority 1-4 years, and had integration training (p<0.05).
Conclusion: Emergency healthcare personnel in Northern Cyprus are primarily nurses. Most of them have not received updated training recently. Studies in which most participants are paramedics will reflect the current situation more objectively. Therefore, structuring emergency health services as a separate unit within the Ministry of Health and the necessary regulations can increase job satisfaction even more.

Authors: Szabo Sylvia , Park Geonwoo , Ahmed Sayem , Park Seree , Danaa Samuel
Published: October 2022

Introduction: Since the outbreak of the COVID-19 pandemic in December 2019, public policy debate has been increasingly focusing on developing and implementing new disease prevention measures based on tracking of geographical location, in particular during the quarantine period. Limited studies have so far investigated possible public acceptance of such measures.
Methods: We analyzed a sample data of 1,000 respondents from the 2021 Korean Social Science Data Center using descriptive statistics and logistic regression modelling. The outcome variable was the binary variable measuring the public acceptance of COVID-19 related tracking devices for people subjected to quarantine, explanatory variable included socio-economic characteristics and subjective perception measures.
Results: The results suggest that subjective factors, such as perceived likelihood of virus contraction (OR=1.78) and severity of the disease (OR=2.21), rather than socio-economic factors, are key determinants of public acceptance of COVID-19 related location tracking technology. Elderly participants in the middle socio-economic class have shown the highest acceptance rate for tracking device implementation
Conclusion: Although the use of location tracking devices has been increasing exponentially, there is still limited understanding in terms of public acceptance of such devices. The results of this study contribute to identifying such determinants, this contributing to policy design related to COVID-19.

Accessing Electronic Health Records of the Unconscious Patient
Authors: Gurav Prachi , Panandikar Sanjeev
Published: October 2022

Electronic Health Records are a digital version of paper-based records. Studying previous treatment, care and medications is important for making diagnosis for the current situation. The aim of this paper relates to the use of EHR as a means of communication between patient and health care provider with a focus on how EHRs communicates health information for unconscious patient to physicians. As accessing records requires credentials of patient and if the patient is not in a condition to enter his credentials, this leads to the scope of dynamic access control. Dynamic access control is provided by dividing EHRs into different levels. The basis for these levels is physician’s specialization and patient’s health status. This framework is implemented with the help of a WAMP server using PHP and MySQL.

Authors: Śliwa Mateusz
Published: October 2022

Motivation: Nowadays, economic patriotism is the current social trend affecting a number of aspects related to the economy, the functioning of enterprises and consumers in the conditions of market competition. Companies wishing to maximize their profits and at the same time remain in positive relationships with their customers should pay special attention to the factors that determine the decision-making of young consumers in the selection of goods and services.

Aim: The study pays special attention to current situations related to the internationalization of enterprises operating on the Polish market. The main aim of the analysis is to show a number of determinants influencing the manifestations of economic patriotism among adults up to 35 years of age, which if well understood, will allow entrepreneurs to increase the effectiveness of their managed institutions, as well as the analysis of positive and negative market behavior related to economic patriotism.

Materials and methods: For the purpose of this study, own research was conducted, which brings a new approach to the discussed issue, showing the attitudes of young consumers consistent with the idea of economic patriotism.

Results: People under the age of 35 show a high awareness of economic patriotism and are consumers with a high degree of ethnocentrism. For further effective development of attitudes related to economic patriotism and, above all, their practical realization, a broad initiative is necessary from top-down undertakings on the part of the government, through schools and universities to grassroots social initiatives and realization of the idea of economic patriotism by the individual.

Authors:   Department of Political Science, University of Ibadan, Nigeria, YAGBOYAJU Dhikru Adewale
Published: October 2022

Among the issues of governance confronting Nigeria, security is generally regarded as crucial. There is no doubt about the strong relationship between security and development. This paper takes an opposing view to the dominant approach of a colonially-foisted statist and law-and-order conception of security by successive administrations in Nigeria. The paper emphasizes certain small things that matter for securing the lives of Nigerians, and ensuring sustainable development in the country. These include socio-cultural, economic and political factors that should catalyze citizens’ participation in the national security architecture and in the country’s development aspirations and goals. Data is drawn from secondary sources for the conceptual and theoretical sections of the paper. Primary data is drawn from events analyses, interviews with selected experts in University of Ibadan and from content analyses of selected documents on contemporary politics, economy and society in Nigeria. This is supported by interactions with respondents in selected markets and locations around the country. Political culture, with focus on the prebendalist perspective, is deployed for the paper’s analytic frame. Keywords: Security threats, Endemic corruption, Political culture, Citizens’ participation.
THIRD-PARTY FOUNDING IN INTERNATIONAL COMMERCIAL ARBITRATION: IT IS ABOUT TIME FOR REGULATIONS
Authors:   Gujarat National Law University, Gandhinagar, Gujarat, PACHAHARA Shantanu , GANDHI Vikas ,   Gujarat National Law University, Gandhinagar, Gujarat
Published: October 2022

Third-party funding (TPF) is a species of the common law doctrine of maintenance and champerty. With the burgeoning of global trade, the need for funding arbitral proceeding of high magnitude have witnessed an upward trend. TPF is a method wherein the impecunious party to the dispute enters into a contract with a third-party, who is not a party to the arbitration agreement, to finance the arbitration proceeding and run the risk of either paying or receiving the proceeds, costs, or award awarded against or in favor of such party. TPF, on one hand, provides a gateway to justice to the impecunious party and on the other hand, causes an impediment to the recognition and enforcement mechanism of arbitral awards. TPF flourishes as an alternative to support arbitral proceedings by acting as an investment for the financers but what impact it has on the market, in the long run, is still unclear. TPF assists the struggling party to appoint highly qualified specialists and a learned arbitrator through financial assistance but restricts the party autonomy and raises justifiable doubts as to the independence and impartiality of the arbitrator due to the leverage the financer holds in such an arrangement. Last but not least, TPF may also, at times, result in the disclosure of attorney-client communication to the financer. The present article is an analytical study of TPF as a mechanism in international commercial arbitration and what challenges it poses to its practice. Moreover, the article places reliance on the work of various scholars, and adopting the inductive approach of reasoning, reflects upon the plausible remedies for challenges that TPF poses to international commercial arbitration. Keywords: Third-Party Funding; Commercial Arbitration; International; Challenges; Regulation.
Is God a Rule-consequentialist?
Authors: Hunt William
Published: October 2022

Prima facie, rule-consequentialism as a moral theory would correlate with the concerns of an omnibenevolent being should one exist. Indeed, such a being would be divine, and under the lenses of the three Abrahamic religions, would inter alia, also be omnipotent and omniscient. In this paper, I consider the attitude of such a being to rule-consequentialism in human society. I argue, from a probabilistic perspective, that the evidence of Abrahamic scripture confirms, to a degree, that God would judge rule-consequentialism to be a sound moral theory in different societies. I also consider a similar argument from a secular perspective.

An Opinion based on a Retrospective Study on Vector Management for the Elimination of Visceral Leishmaniasis and its Sustenance
Authors:   Consultant BMGF Project Former ICMR Consultant, Former Scientist E and Head, Vector Biology and Control Division, ICMR- Rajendra Memorial Research Institute of Medical Sciences, Department of Health Research, Ministry of Health & Family Welfare, Govt. of India, Agamkuan, Patna, Bihar, India., Kumar Vijay
Published: October 2022

Background: Visceral leishmaniasis (Kala-azar, VL) is a vector-borne illness that affects people all over the world. Indoor Residual Spray (IRS) has been recognised as a tool for eliminating the illness. In the context of Kala-azar elimination, it is critical to address evidence-based studies on IRS success and failure. Methodology: For the literature search, the Internet was used. The following websites were visited: PubMed, Google Search Engine, ResearchGate, NVBDCP sites, and WHO/TDR sites. We utilised keywords like leishmaniasis vector, indoor residual spray, eradication of visceral leishmaniasis, and sand fly ecology in our search, and we also visited the library of ICMR-RMRI for the journals which we could not find on the internet. Result: The success of IRS may be shown in the progress made in controlling kala-azar in Assam via vector control. This accomplishment, however, could not be duplicated in Bihar. We looked at all of the studies that dealt with insecticides and vector control. In addition, policies and papers produced by the Indian government and the World Health Organization (WHO) from time to time were included. Suboptimal pesticide usage, a lack of effective IRS M&E, and the use of resistance insecticides have all been concerns in vector control, resulting in failure to meet elimination objectives. Conclusion: It is suggested that strong Monitoring and Evaluation (M&E) is needed particularly during the low transmission period. Restrictive use of insecticide associated with other control measures will be helpful. Determination of infectivity rate in vector and accordingly application of intervention will stop the unscrupulous use of the insecticide.
Innovative T&D Switching Equipment and Development of its Testing Technology
Authors: Smeets René P.P. , Derviškadić Arman , Hofstee Adriaan B. , Nijman Roy M. , Belda Nadew A. , Baum Benjamin
Published: October 2022

A short overview of the developments in the overall transmission and distribution industry in South East Europe is presented in this contribution. Furthermore, as the present journal focuses on breaking and switching in HV and MV switchgears, several technology innovations in T&D switchgear have been identified, at global level. In almost all cases, the ongoing energy transition is the main driver of these innovations. In this contribution, based on test-experience and overview of the industry, innovations are grouped by drivers, with each of them having its impact on testing technology.

These drivers are the following:

1. Increase of ratings: the ongoing trend of co-existence of micro-, local- and super-grids. The consequences for testing of switchgear for UHV and very large current are highlighted:

2. Offshore transmission: compactness and reliability are requirements stretched to the limit for this application. Very long cables for AC and HVDC power transmission, even in a multi-terminal topology will have impact on switchgear.

3. Health safety and environment: here, the major switchgear related discussion is on SF6 replacement and reduction of electrical losses. Various issues related to SF6 replacement will be highlighted. In addition, a recent project intended to quantify the hazard of aluminium bus bars in power stations affected by long duration fault arcs is described.

4. HVDC and power electronics: circuit breakers are going to be installed in multi-terminal HVDC grids. Testing of HVDC breakers, regarding the complete interruption current process is described.

5. Digitalization: switchgear is going to be communicating with the IEC 61850 communication protocol. This will impact testing for which laboratories need to prepare. The introduction of smaller micro-electronics (sensors, IED) closer to primary HV components and its high-frequency transients need careful consideration regarding operation, endurance, and lifetime.

6. Resilience and fault mitigation: Resilience against severe weather conditions, vandalism and cyber-attacks calls for resistant equipment and robust mobile equ ipment/substations that can 6be deployed very rapidly still having an extreme degree of readiness and availability.

7. Quality assurance of products in the face of a pandemic and a lockdown requires adequate methods of a remote digital access to test, and factory sites for type testing and inspection.
New Method of Leak Rate Measurement in SF6 Free Medium Voltage Switchgear Using Helium and Ambient Air
Authors: Ana Ricardo Santa , Muchametow Marvin , Ramesh Manjunath
Published: October 2022

The current medium voltage Gas Insulated Switchgears (GIS) predominantly use Sulphur Hexafluoride (SF6) as insulation medium. The leakage tests performed on GIS use either SF6 or Helium medium to ensure gas tightness. However, SF6 has been strictly regulated for the last years due to the high global warming potential effect on the planet. As a response, new technologies are emerging using air as insulation medium. The present work establishes a basic comparison of the leakage rate in a medium voltage GIS using two different leak detection methods: Helium leak detector and Residual Gas Analyser (RGA). Both methods use Helium and additionally RGA using air as tracer gas.
Analysis of Deformations and Von-Misses Stresses of the Main Shaft System in a Load Break Switch
Authors: Hajradinović Džanko , Santamaria Sergio , Delić Sead , Uzelac Nenad , Touhami Maroua , Kapetanović Mirsad
Published: October 2022

This paper presents the study of deformations and Von-Misses stresses of the main shaft system during opening and closing operations of a rotary SF6 load break switch (LBS). The shaft consists of three axially connected parts made of steel where components are on ground potential and of plastic material, which is on high potential. The insulating shaft carries three rotating knife-blade contacts for the three phases. Static deformation of the insulating shaft is calculated by applying a defined torque between the two ends of the shaft. The results allow deducing the dynamic deformation. Maximum values of Von-Misses stresses are located at the geared connection between the plastic and the steel shaft. The rotation of the shaft system is measured synchronously by two optical rotary encoders in the front and rear sides of the LBS. The results confirm the twisting of the shaft system and provide its elastic deformation values. Travel curves obtained on both side of the LBS show different courses with respect to overtravel and rebound. Discrepancies can be explained by the deformation of the main shaft due to the acting forces, whereas manufacturing tolerances resulting in loose have a certain contribution.

This paper describes the advantages of using data acquisition systems and software modelling tools to support the assessment and therefore redesign of the existing medium voltage switchgear. A 38kV/630A load break linear puffer (LP) will be used as an example for this study. In house testing was conducted to capture important design parameters of the switch such as displacement, velocity of mechanical parts and gas pressure using various sensors and three different measurement setups. The first setup, which is primarily intended for no-load measurements, consists of a DAQ system equipped with different types of sensors - two rotational encoders, three laser-based distance sensors, six pressure sensors, contact separation measurement, and a high-speed camera integrated and synchronized with the measurement system. The second and third setups, which are suitable both for no-load and on-load measurements, are based on state-of-the-art DAQ systems, which use three piezo-electric based pressure sensors, two fibre-optic based pressure sensors, three laser-based distance sensors and a high speed camera synchronized with the measurement system. The data acquired by the measurement systems is used in combination with an in-house developed simulation software HV CB Simulation, which enables simulating and predicting various variables of switching devices. Moreover, high speed camera videos analysed with both commercial and in-house developed image processing software, visualize and reveal many otherwise inaccessible occurrences. In addition to a comprehensive analysis of the proposed data acquisition and simulation setups, three design improvements in the linear puffer design - increase of the opening speed, removal of the flexible conductors and the length increase of the puffer cylinder - are presented and discussed in this paper.

Published: October 2022

With the development of the economy, people’s living standards are getting higher and higher. People will look for ways to relax after busy work, and rural tourism is a slow-paced life. The purpose of this paper is to analyse the evaluation system of rural sustainable tourism land based on ecosystem service value. In this paper, an evaluation model based on AHP and association rules is proposed, and the two methods are described in detail. The experimental results of this paper show that the number of tourists has increased from 12 % in 2014 to 24.9 % in 2020, and the growth rate of tourism revenue has increased from 24 % in 2014 to 30 % in 2020. Rural tourism is an important part of tourism and an important force to implement the strategy of rural revitalisation. It plays an important role in accelerating the modernisation of agriculture and rural areas, the integrated development of urban and rural areas, and poverty alleviation in poor areas. The number of farm stays has increased from 1.9 million in 2014 to 3.25 million in 2020. It can be seen that with the growth of time, the rapid development of the economy, and increasing people who love to travel, this has led to changes in the utilisation rate of rural land. Therefore, the research on the evaluation system of rural sustainable tourism land based on ecosystem service value is very meaningful.

Published: October 2022

In recent years, smog has become one of the most disastrous weather events in China, hurting daily life and seriously affecting public health. To explore the school sports participants in a smog environment based on risk cognition and communication. This study used literature, questionnaire, and other research methods to deeply understand the current situation of school physical education in the haze weather environment. The spatial autocorrelation index tested the spatial agglomeration characteristics of smog pollution. As was evidenced, sports in a smog environment can cause physical discomfort and mild psychological stress. The significant difference in maximal oxygen uptake was p < 0.01. The level of students’ perception of smog positively correlates with students’ active of physical exercise, and it has a significant predictive effect. The explanatory power of smog perception level to resisting coping behaviour is 49.5 % (R

= 0.495, P < 0.001). Under the influence of smog, participants in school sports activities showed high smog risk cognition and weak coping behaviour, and schools showed low smog risk communication. Experience and policy supervision explain 50.1 % of the information on risk communication influencing factors, with high explanatory power. One can conclude that outdoor teaching and practice in physical education classes should be carried out because the outdoor air does not influence the human body to enhance physical fitness and health.

A preliminary inventory of macroinvertebrate communities and a regular physicochemical analysis of groundwater were carried out in the Souk Ahras region (north-eastern Algeria). It aims to study and analyze the structure and distribution of underground aquatic species, thus determining the relationship that may exist between the quality of water in wells and springs with the diversity of aquatic fauna present in the habitats. Through 2018, 14 stations (10 wells and 4 springs) were monitored on a monthly basis, while water and aquatic fauna samples were taken. A principal component analysis (PCA) of the physicochemical quality parameters was carried out from the average values of each parameter. It has been observed that the waters are highly mineralized, due to the high values of total hardness, salinity, and sulfate levels in certain stations. The sources of contamination are mainly due to the raw wastewater circulating in the small canals. Also “seguias” are used either to evacuate wastewater or for irrigation, which seeps down to the water table. The collected aquatic fauna in all the 14 stations is diversified and contains 29 families which correspond to 4 taxa.
Analysis of the impact of macroeconomic factors on real estate prices in Bosnia And Herzegovina
Authors: Stanković Dragan
Published: October 2022

Economic theory and practice are not acquainted with any unique set of macroeconomic factors that affect real estate prices. The very complexity of this phenomenon relativizes any attempt to establish an unchanged list of macroeconomic factors in BiH. The aim of the research in this paper is to analyze the impact of selected macroeconomic indicators on real estate prices in BiH, in the period from 2007 to 2019. Out of numerous macroeconomic factors that affect real estate prices (real estate prices are viewed as: the value of construction works done and as the value of new dwellings - new construction), 12 macroeconomic factors were singled out: nominal gross domestic product, real GDP growth rate, industrial production growth rate, GDP per capita, average net wages, imports and exports, household deposits in commercial banks, interest rate (housing loans, annual, %), loans to households, household final consumption expenditure, gross fixed capital formation and government final consumption expenditure. Starting from the hypothesis that macroeconomic factors affect real estate prices, it has been concluded that the selected factors significantly determine real estate prices and that most of the predictor variables defined in the model are significant, in terms of impact on the movement of GDP and real estate prices in Bosnia and Herzegovina in the period analyzed. The greatest impact on real estate prices is by household final consumption expenditure, GDP per capita, nominal GDP, interest rate, household deposits and real GDP growth rate. The research used factor analysis (reduction of macroeconomic factors to the optimal number of factors that explain the analyzed phenomenon and its impact on real estate prices) and an extended multiple linear regression model with a statistical software program SPSS, version 21. Modeling the impact of macroeconomic factors on real estate prices has macroeconomic effects and benefits for the country and contributes to the growth and well-being of operators in the real estate market.

Mobile telecommunication sites are an essential station in our technological life, used to allow the communication through mobiles and internet. Many telecommunication sites are installed in remote areas where the grid is not available. For this, hybrid renewable energy systems (HRES) are used to power the stations and integrate the remote areas with the world. This article aims to evaluate the performance of the existing HRES of the remote mobile telecommunication station of Bougaroun, Collo, Algeria -which consists of PV modules, batteries and diesel generator (DG)- and to develop it using a mathematical model to demonstrate the effect of deploying a wind turbine to supply more green energy, minimize the operation cost (fuel consumption and maintenance), and reduce the greenhouses emitted by the DG. Based on the wind data at the site location, the obtained results show a significant amount of output power that can be used to minimize the DG functionality.
