Access to energy is crucial in tackling many of the current global development challenges that impact on people’s economic, health and social well-being as well as the ability to meet the commitments of reducing carbon emissions through clean energy use. Despite increased attention from multiple governments and agencies, energy poverty remains a serious sustainable development issue in many developing countries. To date, most research have focused on general access to electricity and the generation of clean energy to replace fossil fuels, failing to address the lack of basic access to clean energy for cooking and heating. More people in the world lack access to clean cooking fuels than to electricity. This issue is one aspect of a broader research which investigates the impacts of optimized energy policy and energy business models on sustainable development in developing countries.

AbstractThe COVID-19 pandemic and infection control measures had an unavoidable impact on surgical services. During the first wave of the pandemic, elective surgery, endoscopy, and ‘face-to-face’ clinics were discontinued after recommendations from professional bodies. In addition, training courses, examinations, conferences, and training rotations were postponed or cancelled. Inadvertently, infection control and prevention measures, both within and outside hospitals, have caused a significant negative impact on training. At the same time, they have given space to new technologies, like telemedicine and platforms for webinars, to blossom. While the recovery phase is well underway in some parts of the world, most surgical services are not operating at full capacity. Unfortunately, some countries are still battling a second or third wave of the pandemic with severely negative consequences on surgical services. Several studies have looked into the impact of COVID-19 on surgical training. Here, an objective overview of studies from different parts of the world is presented. Also, evidence-based solutions are suggested for future surgical training interventions.

And Performance

While our planet is rapidly approaching an environmental crisis under the dominant use of depleting fossil fuels, the need for exploiting all forms of new, small carbon foot-print, renewable, and clean energy resources are increasing in the same proportion. Therefore, the need for exploring all types of clean energy resources that the world has- some of which might have not attracted sufficient attention before- is essential in order to implement sufficient, efficient, and widely use all them. In this respect, operational effectiveness of the wind and hydrokinetic turbines depend on the performance of the airfoils chosen. Using double-blade airfoils in the wind and hydrokinetic turbines, minimum wind and hydrokinetic flow velocities to produce meaningful and practical mechanical power reduces to 3- 4 m /s for wind turbines and 1-1.5 m/s or less for hydrokinetic turbines. Consequently, double-blade hydrofoils may re-define the potentials of wind power and hydrokinetic power of the countries in positive manner.

The Impact

Sustainable development is now an important direction for the further development of all economies in the world. It is important to balance economic development with the impact on the environment and our planet. Another direction in the development of management sciences is the emergence of the concept of Corporate Social Responsibility, which considers this impact in three key aspects—economic, environmental and social—in terms of microeconomics. This concept gives companies specific guidelines and tools that minimize their negative impact on the environment. Reducing the negative impact of companies influences the environment and this is what is mainly associated with them. However, companies should also pay attention to internal consistency and caring for employees. Company practices such as the exploitation of people, including children, and injustice in the workplace are some of the factors that can be observed in less developed countries. The article focuses on the presentation of the environmental aspect in the context of the concept of corporate social responsibility. We analyzed individual sectors of the economy in terms of the environmental aspect, with particular emphasis on the energy industry. The study is based on a statistical analysis taking into account data from 1718 companies from all over the world. The aim of the article is to present the environmental aspect in the context of corporate social responsibility in the energy industry as a direction for sustainable development of the economy. The article is based on the analysis of the literature and databases presenting CSR, which was created on the basis of questionnaire research. The article shows which regions of the world are worse and which are better in terms of the environmental aspects of CSR. Conclusions on the main CSR guidelines for the environment are also presented. We analyzed factors such as environmental routines, policies and targets, implementation of environmental management systems, ISO 14001/EMAS certification, environmental reporting, environmental requirements inside the supply chain, the trend of GHG emissions and the trend of energy consumption for their environmental impact. The analysis was carried out on the basis of given regions of the world and individual sectors of the economy, especially the energy industry.

The Impact

Cement production is an energy-intensive process. Utilisation of fossil fuels is common practice in the cement industry around the world. Alternative fuel substitution rates increase every year. More specifically, 18 % of the fuel used by the European cement industry in 2006 consists of alternative fuels. This study aims to investigate the prospects for the partial replacement of conventional fossil fuels currently used in the TITAN cement factory in Thessaloniki, Greece, with alternative fuels, focusing on the impact of alternative fuel use on the emissions of air pollutants from co-incineration operations. Air emissions were estimated for both the conventional fuel and mixtures of conventional fuel with alternative fuels, based on emission factors found in the literature but also using the measurements conducted by TITAN in 2010. Emission estimates indicate that legislative limit values for all pollutants are not exceeded. Based on the emission estimates and measurements in the flue gas, the dispersion of the plume around the factory has been described with an appropriate numerical simulation model. Results suggest that the factory’s contribution to the air pollution levels in the surrounding area is very low for most regulated pollutants.

The article analyzes the impact of the COVID-19 pandemic on the world insurance market and some European countries. Separated economic indicators of the impact of the COVID-19 pandemic on the insurance business of the world are singled out. It was determined that the impact of the COVID-19 pandemic inspired declining incomes of insurers and households, rising unemployment, declining demand for insurance services, a significant decline in productivity of insurance companies, uncertainty about the future development of the insurance industry and the effects of the pandemic. The experience of the world insurers' struggle against the consequences of the COVID-19 pandemic has been studied and generalized. The latest tools that have allowed insurers around the world to mitigate or mitigate the negative impact of the crown crisis, in particular, are: the development of new insurance products; increasing the level of requirements for insurance services in terms of its relevance, price flexibility, mobility and transparency; transition of insurers to online sales of insurance services and online payments for insurance cases; direct funding of specific means of combating COVID-19; use of the latest technologies and innovative methods in the insurance business; introduction of a new mode of staff work in the activities of insurance companies. The transition of insurers to online sales of insurance services and online payments has revealed many unresolved issues regarding the insurer's cybersecurity. Insurers are forced to improve existing technologies and methods of control, to intensify training and information activities. The Crown Crisis has significantly increased the importance of modern underwriting. Therefore, insurers around the world are using the capabilities of artificial intelligence, alternative data sources and better forecasting models. Greater understanding of pandemic processes, gaining experience is needed not only to accelerate the way out of the modern pandemic, but also to form a stable insurance system to the inevitable future challenges. The study of positive experience in the functioning and development of insurance markets around the world in crises and shocks is useful for application in national practice.

The Impact

The economic crises of the 21st century have severely damaged the world economy. The first big crisis began in 2008 with the bankruptcy of one of the largest banks in the US, the Lehman Brothers Bank. The next crisis mainly affected Europe and was associated with the disclosure by the Greek government in 2009 of the dire state of public finances and huge monetary embezzlement. This crisis had a negative impact on many European countries belonging to the euro zone, as well as on many other countries outside this area, indirectly reducing investment or limiting international trade. Another crisis is related to the coronavirus pandemic announced at the beginning of 2020. At that time, most countries in the world have made a "lockdown" of the economy for many weeks. Various sectors of the economy were restricted or completely shut down almost overnight, seriously affecting societies
