The cost-effectiveness of a range of variants of single-house sewage treatment plants is analyzed in the article. They include plants with drainage pipe, with package drainage, with tunnel drainage, constructed wetlands, activated sludge chamber, biological filter and a hybrid plant. The analysis focuses on different ways of discharging treated wastewater, i.e. drainage pipe, package drainage, tunnel drainage, pond and soakaway. Selection of the most financially efficient system was made on the basis of the minimal rate of the average annual treatment cost. The total cost was compared with the construction costs as well as the operating costs of a holding tank. The analysis shows that, on the average, the total average annual cost of single-house sewage treatment facilities is almost 2-times lower than the cost incurred on the construction and operations of a holding tank. This ratio, however, depends largely on different prices for emptying a tank. Materials (avg. 83%) and equipment rental (avg. 12%) constitute the greatest share of the investment costs incurred on the construction of sewage treatment plants. Among the analyzed sewage treatment plant technologies the lowest investment outlays are required for drainage pipes and packages as well as constructed wetlands. The lowest treated sewage discharge costs are generated by ponds, whereas the highest by tunnel drainage. The lowest operation costs are generated by constructed wetlands, whereas the highest by holding tank, activated sludge chambers and hybrid plants. The most cost effective, characterized by the lowest average total annual cost, is constructed wetland with discharge by a pond. The greatest average annual cost of wastewater treatment is generated by hybrid plants with treated wastewater discharged into the ground by drainage tunnels. The conclusions of analysis carried out by other authors are similar to those presented in this paper. However, the presented research shows that the average annual outlays for wastewater treatment for all plants are greater. This is because additional cost factors, such as the purchase of gravel, human costs, equipment expenditures or maintenance of periodic inspections carried out by qualified personnel, were taken into account. These are costs without which it is impossible to achieve the required quality of treated sewage.

The aim of this article is to assist anyone considering implementing these systems. Along the document the main differences between conventional and remote control are stated, with the intention to clarify what advantages they can bring, the changes involved when adopting remote towers, and a brief outline of a transition plan for adopting these systems. Subsequently, the benefits to a country’s air navigation from utilizing these systems is discussed by studying the case of Colombia, a country with a unique orography. In addition, the specific characteristics of the airports are analysed to propose the candidates which may have the best outcome if remote tower systems are implemented.

The purpose of this article is one of the benchmarking methods - SFA (Stochastic Frontier Analysis) and overview of the areas of applications. This article discussed the idea of the method and the basis of economics. The literature review of previous achievements on the areas of application was researched. SFA is compared to most popular DEA method (Data Envelopment Analysis). The interest method over the last decade and the industries that are the subject of analysis is presented. The summary contains the conclusions of the analysis.

Cel: przedłożony artykuł koncentruje się na celu, jakim jest rozwiązanie problemów, na jakie napotykają europejskie systemy ochrony zdrowia. Konstrukcja/Metodyka: artykuł składa się z dwóch części. Pierwsza z nich ma charakter teoretyczny i przedstawia interdyscyplinarny dorobek badawczy. Druga część zawiera przykłady rozwiązań wdrożonych w Szwecji, Niemczech i Wielkiej Brytanii. W pierwszej części dokonano przeglądu monografii i artykułów poświęconych metodyce tworzenia VBHC. Część empiryczna oparta jest na raportach przedstawiających wprowadzanie VBHC. Wyniki: chęć poprawy efektywności kosztowej i klinicznej skuteczności wskazuje na potrzebę wdrożenia VBHC. Koncepcja VBHC powinna zatem przyczynić się, zdaniem ekspertów, ekonomistów oraz specjalistów od finansów i zarządzania do poprawiania efektywności ekonomicznej i skuteczności klinicznej. Ograniczenia/implikacje badawcze: niestety jest to długotrwały proces poprzedzony wieloma czynnościami. Do najważniejszych z nich należy stworzenie rejestrów medycznych i baz danych. Dzięki nim możliwe jest tworzenie kluczowych wskaźników działalności (KPI) pozwalających na prowadzenie racjonalnej polityki zdrowotnej. Oryginalność/wartość: do dorobku zawartego w publikacjach przedłożony artykuł dodaje konieczność uwzględnienia odpowiednio wybranych KPI analizujących środowisko makroekonomiczne do funkcjonowania szpitali.

Purpose: The submitted article focuses on how to solve the problems faced by the European healthcare systems. Design/Methodology: The article consists of two sections. The first one is theoretical and presents interdisciplinary achievements of researchers. The second section includes examples of solutions applied in Sweden, Germany and Great Britain. In the theoretical part, books and articles on the methodology of VBHC creation were reviewed. The empirical part is based on reports on the introduction of VBHC. Findings: The desire to improve cost and clinical effectiveness indicates the need for a value-based healthcare (VBHC). Thus, the concept of VBHC should contribute, according to experts, economists as well as finance and management specialists, to the economic efficiency and clinical effectiveness. Research limitations/implications: Unfortunately, this is a lengthy process to be preceded by many activities. Healthcare registers and databases belong to the most important ones. Thanks to them, it is possible to create the key performance indicators (KPI) allowing for a rational health policy. Original value: To the achievements contained in the publications, the submitted article adds the need to take into account appropriately selected KPIs analyzing the macroeconomic environment for the functioning of hospitals.

The Directive 2002/91/EC of the European Parliament and of the Council on the energy performance of buildings requires that investors and owners of the building fulfil requirements relating to the energy performance of the buildings. The purpose of the Directive is to support a decrease in the energy performance of the building, taking into account outdoor climatic and local conditions, requirements relating to the inside microclimate and efficiency of costs.
