Rapeseed (Brassica napus L. var. Napus) is a plant pollinated by insects. In climatic conditions of Poland, it is visited mainly by honeybees (Apis mellifera). In 2015, 947,000 hectares were sown with rape, producing 2.7 million tons of grain [1]. Every year, significant losses in the yield of this plant are observed, caused mainly by pathogenic fungi, including: Plasmodiophora brassicae Wor., Leptosphaeria biglobosa Shoem. et Brun, L. maculans Desm., Alternaria brassicae Berk.,

Knowledge is a corporate resource, being grounds for initiating activities, which is important in a dynamic economy. The difficulties related to obtaining tacit knowledge, related primarily to experience and observation of the knowledge employee (Mendryk, 2011), encourage the companies to use tools supporting knowledge management and location. This article attempts at designing a dedicated, strategic knowledge map for a research and development department in a manufacturing company. Based on the reference works, the detailed characteristics of specific sources of knowledge in a manufacturing company and tools supporting the process of converting the tacit knowledge into explicit one, for example, the knowledge maps, were devised. Then, a strategic knowledge map model was designed for the research and development department (hereinafter abbreviated as SKM – R&D) in the manufacturing company, comprising the following components: (1) fields of knowledge, (2) internal and external processes in the R&D department, and (3) sources of knowledge. Then, a practical implementation of the SKM – R&D model was presented.

This article elaborates the authors' method for tacit knowledge acquisition focused on a research and development department in a manufacturing company. It presents a case study of the use of concepts for tacit knowledge acquisition and is based on a survey and data obtained from 85 Polish and German Manufacturing Companies from the cross-border cooperation region of Lubuskie/PolandBrandenburg/Germany. This article develops a framework of tacit knowledge acquisition in a manufacturing company and further discusses the research results.Keywords: tacit knowledge, knowledge acquisition, research and development department, manufacturing company. IntroductionFor manufacturing companies functioning in the knowledge-based economy, their knowledge is now known as a key source for their development (Nycz, 2011). Moreover, knowledge is also the main source for any action in innovative enterprises and can increase the market value of a company (Drucker, 1964). The implementation of new tasks in a company is frequently based on interdisciplinary knowledge that is rooted in the minds of different specialists. According to Wąsowicz (2013), knowledge should be accumulated to create a possibility of the exchange of experience gained from working on projects within a company. Knowledge is defined as consisting of tacit knowledge (acquired from employees) and explicit knowledge (defined in the form of company policies, regulations, procedures, policies, etc.). In this paper, special attention is paid to tacit knowledge acquisition. Additionally, knowledge in a company can be obtained from internal sources of the company as well as from external sources (Prodan, CoticSvetina, 2008; PatalasMaliszewska and Krebs, 2015). Our motivation to study this approach came from the research results obtained from Polish and German manufacturing companies 1 .1 This work was supported in part by the project realized by Justyna Patalas-Maliszewska: "Assessing the relationship be-A manufacturing company needs to develop methods to acquire knowledge, especially tacit knowledge. According to Maurer (2010), knowledge acquisition can increase the success of research and development (R&D) projects. This study focuses on the relationships between tacit knowledge acquisitions from identified tacit knowledge sources with factors describing any realized R&D project success. The quest to describe relationships, especially how they lead to an increase of R&D projects in manufacturing companies, was motivated by the authors' research to build a model and method for tacit knowledge acquisition for R&D departments in manufacturing companies.Using survey data from 62 Polish manufacturing companies from the Lubuskie region and from 23 German manufacturing companies from the Brandenburg region, this study discusses the main tacit knowledge sources in a manufacturing company and how they affect project realization in the crossborder cooperative region of Lubuskie/PolandBrandenburg/Germany. The research companies are from the automotive and construction se...

In recent years, general studies on Selective Laser Melting (SLM)/Selective Laser Sintering (SLS)/direct metal deposition (DMD) technologies, as well as studies on detailed issues in this area, have been carried out. However, a research gap is observed in investigations into the features of single tracks in the above-mentioned technologies. On the basis of data published in 2016–2019, an approach was adopted for a preliminary quantitative analysis of the knowledge base and also trends observed in the development of new technologies. This study demonstrates the effectiveness of the data mining technique based on the Bayes algorithm for analyzing trends in processes of additive manufacturing and the practical application of the knowledge received using the Bayes algorithm. After the analyses referred to above were completed, single and double layers of a composite material based on the Ni-based alloy and Fe–Al bronze were analyzed under different processing conditions. The effects of laser spot speeds and pitches on microhardness, microstructure, and interlayers’ features were described. So, the innovative approach, namely, the combination of the analysis of the scientific database of the phenomenon under study and the subsequent experimental investigation of its features, is the scientific novelty of the present study.
