The issue of stability controlling cutting slopes is particularly important in clay-shale slopes, a typical expanding sedimentary layer with poor engineering geological conditions and mechanical characteristics. Therefore, research on the causes of failure and remedies for clay-shale cutting slopes is required to serve as an overview for handling and preserving clay-shale slopes in identical conditions. However, the trusted information about the need for further related clay shale research and clay shale in slope stability has yet to be specifically presented. This review study summarizes the published research for clay shale beginning in 1980, presents a bibliometric analysis to examine the published research based on year and country, and provides various study trends in cluster diagram using the VOSviewer program. The analysis also summarized some key goals, effective methodology, and significant findings from the most recent studies to extract information from them that would benefit future research. In conclusion, the results show the need for developing research to fill the knowledge gap regarding clay shale, landslide, and clay mineralogy. In addition, the clay shale slope analysis has revealed the need for additional research into dynamic force and its deformation.

The post-war reconstruction of the energy sector of Ukraine is a critical issue that requires significant investment in both infrastructure and modernization. However, the limited financing of the public sector is a problem that needs to be addressed. A combination of European Union (EU) grant funding and private funding through public-private partnerships (PPPs) has been suggested as a potential solution to this problem. The relevance of this topic lies in the potential of PPPs to attract resources and experience from both the public and private sectors. This can lead to a more efficient use of resources and can help solve the problems associated with limited public sector funding. In addition, PPPs can provide a framework for sharing risks between the public and private sectors and can help mobilize private sector resources and expertise, which can be critical in post-war recon struction efforts. In addition, a combination of EU grant funding and private funding through PPPs can contribute to broader economic development by promoting investment in the energy sector. This can help stimulate economic growth, create jobs and improve energy security, which is critical for the long-term sustainability of Ukraine’s energy sector. Thus, the topic of combined models of uniting EU grant funding and private funding based on public-private partnership for the post-war reconstruction of the energy sector of Ukraine is extremely relevant for solving problems related to limited public sector funding, attracting resources and experience from both public and private sectors as well as promoting the broader economic development of Ukraine.

Powojenna odbudowa sektora energetycznego Ukrainy jest kwestią krytyczną, wymagającą znacznych inwestycji w infrastrukturę i modernizację. Problemem wymagającym rozwiązania jest jednak ograniczone finansowanie sektora publicznego. Jako potencjalne rozwiązanie tego problemu zaproponowano połączenie dotacji UE i finansowania prywatnego w ramach partnerstwa publiczno-prywatnego (PPP). Istotność tego tematu polega na potencjale PPP w zakresie przyciągania zasobów i doświadczenia zarówno z sektora publicznego, jak i prywatnego. Może to prowadzić do bardziej efektywnego wykorzystania zasobów i pomóc w rozwiązaniu problemów związanych z ograniczonym finansowaniem sektora publicznego. Ponadto PPP mogą zapewnić ramy podziału ryzyka między sektor publiczny i prywatny oraz mogą pomóc w mobilizacji zasobów i wiedzy fachowej sektora prywatnego, co może mieć kluczowe znaczenie w powojennych wysiłkach na rzecz odbudowy. Ponadto połączenie dotacji UE i finansowania prywatnego za pośrednictwem PPP może przyczynić się do szerszego rozwoju gospodarczego poprzez promowanie inwestycji w sektorze energetycznym. Może to pomóc w stymulowaniu wzrostu gospodarczego, tworzeniu miejsc pracy i poprawie bezpieczeństwa energetycznego, co ma kluczowe znaczenie dla długoterminowej stabilności ukraińskiego sektora energetycznego. Zatem temat połączonych modeli łączenia dofinansowania unijnego i prywatnego w oparciu o partnerstwo publiczno-prywatne na rzecz powojennej odbudowy sektora energetycznego Ukrainy jest niezwykle istotny dla rozwiązywania problemów związanych z ograniczonym finansowaniem sektora publicznego, przyciąganiem środków i doświadczeń zarówno z sektora publicznego, jak i prywatnego, a także promowanie szerszego rozwoju gospodarczego Ukrainy.

Manufacturing, as one of the main pillars of a civilized lifestyle, will be strongly affected by sustainability issues, and it will play an important role in establishing a sustainable future. Within the area of sustainability issues, some specific issues are pointed out, such as the energy and labor intensity of manufacturing processes. The main aims of this paper are a systematic literature review and the evaluation of the energy and labor intensity of manufacturing processes in an industrial enterprise while proposing changes toward sustainable development. In the research, 163 scientific publications (77 related to China) were taken from the Web of Science (WoS) database based on selected keywords describing the studied phenomenon. The analyzed publications were divided into five areas (clusters). In terms of evaluating the energy and labor intensity of manufacturing processes, twelve production processes were selected, which were then grouped according to their most important areas of similarity (automation, ergonomics, and discomfort). The systematic literature review was carried out using the VOSviewer software, version 1.6.14. This article also uses the methodology of a case study with a simplified SWOT analysis based on interviews with employees and expert panels. The subject of the research is an industrial enterprise representing the steel manufacturing sector in Poland.

Lean thinking and Industry 4.0 have been broadly investigated in recent years in intelligent manufacturing. Lean Production is still one of the most efficient industrial solutions in business and research, despite being implemented for a long time. On the other hand, Industry 4.0 has been introduced referring to the fourth industrial revolution. This study aims to analyze the combination of both Industry 4.0 and Lean production practices through a systematic literature review from a Lean Automation perspective. In this field, 189 articles are examined using VOSviewer for cluster analysis. Then, a more detailed analysis is provided to explore how Industry 4.0 and Lean techniques are integrated from a practical perspective. Results highlighted Big Data Analysis and Value Stream Mapping as the most common techniques, also emphasizing a growing trend toward new publications. Nevertheless, few practical applications are identified in the literature highlighting six gaps in the correlation of LA practices.

This paper provides an overview of scientific and patent publications in furniture design and their connections from 1972-2020. The scientific publications were searched in the Scopus database, while the number of patent documents available in The Lens database was an indicator of the innovations in furniture. 1,465 scientific publications and 2,880,188 patent documents were identified. The results show that: authors from China and the USA published the largest number of scientific works, authors from the USA are the most often cited, there are 15 outstanding institutions from which the authors of the largest number of analyzed articles come, i.a.: University of Zagreb (Croatia), Poznań University of Life Sciences (Poland), Central South University of Forestry & Technology (China), Wood Technology Institute (Poland), Delft University of Technology (Netherlands) and others. The analysis of co-authorship shows cooperation in four groups of countries: (1) Brazil-Netherlands-Portugal, (2) the United States and a wide group of cooperating countries, (3) China-UK-Japan, and (4) Croatia-Poland-Turkey. The annual number of scientific publications and patent documents are strongly correlated. The increase in the number of scientific publications is much more than the increase in the number of patent documents. The statistical Granger causality test does not predict the patent documents' annual number trend by the scientific publications time series. The results presented in this article may facilitate scientific cooperation in "furniture design" showing leading authors and institutions.
