Machinery faults are a problem that incorrectly diagnosed may result in the increase of waste. The fault mentioned in the article was identified at an opencast facility located in Podkarpacie. The ...purpose of the study was to analyse the defect identified on the excavator arm using quality management techniques. These techniques were the Ishikawa diagram and the 5Why method. In the plant, unit faults on various types of machines were detected. The fracture on the excavator arm was identified, however, the cause of the problem was not known. Potential causes of the fault and the main cause of the problem (material fatigue) were detected using the Ishikawa diagram. The root cause of the material fatigue, the long-term and repetitive operation of the excavator during the excavation of the deposit, was identified by the 5Why method. The proposed processes can be used to identify the root causes of various faults both in the mining industry as well as production and service plants.
BIM (building information modeling) is a kind of technology that has great potential to enhance the level of automation in architecture, engineering, and construction (AEC) projects. The created ...virtual model of the facility allows coordinating all industries during the entire life cycle of the building. The possibility to save the data related to the given facility in one place, namely in the BIM model, enables control and management of the AEC projects at every stage. During the design and implementation phase, BIM models facilitate the optimization of time, costs, and quality, and in the operational phase, they support effective management of the facility. The use of BIM for building energy modeling (BEM) is the next step of evolution in architecture and engineering design practice. The benefits of using the BIM approach are widely discussed in the literature; however, they may be hard to achieve if appropriate attention is not directed to minimizing the barriers to the implementation of this technology. Observing Europe, one can notice that western and northern countries successfully use BIM for their needs, while the countries of the Eastern Bloc, including Poland, introduce it at a slower pace. In the present paper, the authors conducted a cause-and-effect analysis of the identified barriers to the implementation of BIM technology in the construction process. For this purpose, the authors applied the Ishikawa diagram, which is a tool that helps to recognize the actual or potential causes of failure. The analysis conducted showed that one of the weakest links in the successful BIM implementation is people and, in particular, their lack of knowledge and reluctance to change. The authors indicated the need to introduce and strengthen preventive actions, mainly through education: training, courses, and studies focused on BIM technology.

Results and Discussion: The training was synchronous and remote, making it possible to represent other states. Most participants were unfamiliar with the QbD approach and the Ishikawa Diagram. Based on the discussions, an action plan was developed whose focus was to solve the problem of storing biomolecules.
Research Implications: The use of these tools can improve the reliability and reproducibility of data in scientific research, as well as reduce waste of material and process time.
Originality/Value: This study promotes discussion on how the QbD approach, widely used in industry, would assist in the detection of control points and risk analysis to be incorporated in the process of obtaining biomolecules and in analytical experimentation protocols, within laboratories of research.

The aim of the work was to determine the effectiveness of the use of the Ishikawa diagram and the Pareto-Lorenz diagram in the analysis and assessment of threats that occur in small sports and ...recreation infrastructure - playgrounds. After analysing the available literature, it can be concluded that there are studies in the field of safety on playgrounds, but there are no publications combining surveys with the use of quality management tools in relation to this topic. Through a direct survey conducted among parents and caregivers, information was obtained about the threats in playgrounds located near housing estates they meet most often. Using the Ishikawa diagram, this information was grouped and a brainstorming session was conducted to isolate the root causes of these threats. After conducting an analysis using the Pareto-Lorenz diagram, the threats that appeared most frequently in the respondents' responses were specified. The result of the work is to propose actions that can reduce or eliminate these threats.
The present study deals with the formulation of topical insulin for wound healing with extended stability and sustained release, by applying quality by design concepts. Insulin has been promoted as a ...promising therapeutic wound healing agent. Topical formulation of insulin faced major problems, as it cannot be delivered safely to the wound with a controlled rate. Formulation of insulin-loaded vesicles in optimized bio-adhesive hydrogels has been explored to ensure a safe delivery of insulin to wounds in a controlled manner. Quality by design (QbD) was applied to study the effect of several critical process parameters on the critical quality attributes. Ishikawa diagram was used to identify the highest risk factors, which were screened by a fractional factorial design and augmented by Box–Behnken design. The optimized formula was incorporated into a mucoadhesive gel, which was further subjected to stability and clinical studies. An optimized formula was obtained with a particle size of 257.751 nm, zeta potential − 20.548 mv, 87.379% entrapment efficiency, and a release rate of 91.521 μg/cm

/h. The results showed that liposomal insulin remained stable for 6 months in aqueous dispersion state at 4°C. Moreover, the release was sustained up to 24 h. The clinical study showed an improvement in the wound healing rate, 16 times, as the control group, with magnificent reduction in the erythema of the ulcer and no signs of hypoglycemia. Insulin-loaded liposomal chitosan gel showed a promising drug delivery system with high stability and sustained release.
Material production processes are special processes. As part of continuous improvement, it is extremely important to find the causes of the incompatibilities that occur in them. To increase the ...effectiveness of these actions, different methods are used. The purpose of this study was to present an original method that allows the classification to improve the combinations of actions of product with material incompatibility. The originality of this method allows for the sequential and coherent operation of adequate analysis techniques of causes resulting in incompatibilities in the product material and, consequently, identifying the reasons that influence their quality. The presented method was developed using a new combination of brainstorming (BM), the Ishikawa diagram with 5M rule, the DEMATEL method, and the algorithm used in the MATLAB software. As a result of the proposed applied method, it is possible to create a sequence of actions that include interactions between important causes of product incompatibility, which was supported by the test of this method. This method was shown to support the creation of a rank of importance of improvement actions. This ranking allows for improvement of any product according to the possibilities of enterprises and simultaneously allows for reducing or eliminating products’ incompatibilities.
