    Opis:
    Development of the automotive industry, including so-called dowsizing and rightsizing, entails the need to ensure, and hence to verify, the stringent cleanliness levels of an increasing number of car components. The assurance of proper cleanliness level requires knowledge of the entire production process and precise information on the contaminants that will allow to identify their sources. Obtaining reliable cleanliness information requires establishing of many different factors, i. a. selection of proper contamination extraction and collection technique, proper parameters of extraction, validation of extraction procedure, methods of particles analysis. Analytical techniques which are implemented include gravimetric, optical microscopy and advanced techniques like scanning electron microscopy. This work present’s actual state of knowledge regarding technical cleanliness analysis of components. Important aspects of QA&QC in technical cleanliness assessment are also discussed.

    Opis:
    The difficulty of innovation risk assessment makes it necessary to use a multi-criteria analysis. Innovative projects are related to unstructured problems and the uncertainty, therefore, the use of fuzzy logic in the innovation risk assessment is analyzed. This paper proposes a method of determining the weights of criteria in order to innovation risk assessment. The weights are determined by 5 general criteria and 14 detailed criteria of innovation risk assessment. The proposed method is an extension of the fuzzy AHP method. The extension consists in taking into consideration the group decision-making approach with experts’ psychological conditions. The groups of experts have been chosen based on an elaborated form. The form makes it possible to characterize the persons within the scope of different psychological conditions. The proposed method provides objective and rational decision-making. The paper presents also a comparison of results with the fuzzy AHP method without the group decision making. The weights obtained by the proposed method are more diversified and bring out the most important criteria.

    Opis:
    This study primarily includes theoretical information on the performance and lost productive time of a firm. Furthermore t-shirt sewing operations of a garment firm were analysed and time measurement for each operation was carried out by the time keeping method. By considering the measurements obtained, different performance estimations, the firm’s lost productive time rates, and the standard time was calculated within 5 different scenarios. According to each sewing standard time obtained, the assembly line balancing practice was carried out using the Hoffman method. Later on results of the assembly line balancing were compared, and the importance of employee performance assessment and its lost productive time rates for firms were discussed. The aim of the study was to emphasize the value of impeccable determination of the employee performance assessment and lost productive time rates. Consequently garment firms will be more cautious in calculating the standard time and will be able to reach their production target within the accurate measurement they obtain.

    Opis:
    Emotions are an important element of advertising and have a decisive influence on its effectiveness. The aim of the presented article is to assess the differences in the level of emotions present in advertising texts created by a copywriter and a text generator based on artificial intelligence (AI). Sentiment analysis performed through the IBM Watson NLU application was used to assess emotions. This study provides information on the emotions present in radio advertisements for pharmaceuticals, and enables the identification of differences between human and AI generated text sources. The results show that ads from both sources have a similar emotional level, with the exception of the category "disgust", which in this situation can be used as an indicator of the origin of the ads. The results described refer only to radio advertisements for pharmaceuticals. At the end of the article, recommendations for business are formulated and directions for future research are indicated.
    Emocje są ważnym elementem reklamy i mają decydujący wpływ na jej skuteczność. Celem prezentowanego artykułu jest ocena różnic w poziomie emocji obecnych w tekstach reklamowych tworzonych przez copywritera i generator tekstów oparty na sztucznej inteligencji (AI). Do oceny emocji wykorzystano analizę sentymentu przeprowadzoną za pomocą aplikacji IBM Watson NLU. Badanie dostarcza informacji na temat emocji obecnych w reklamach radiowych produktów farmaceutycznych, a także umożliwia identyfikację różnic pomiędzy źródłami tekstowymi generowanymi przez człowieka i AI. Wyniki pokazują, że reklamy z obu źródeł mają podobny poziom emocjonalny, z wyjątkiem kategorii "obrzydzenie", która w tej sytuacji może być wykorzystana jako wskaźnik pochodzenia reklamy. Opisane wyniki odnoszą się tylko do radiowych reklam farmaceutyków. Na końcu artykułu sformułowano zalecenia dla biznesu oraz wskazano kierunki przyszłych badań

    Opis:
    With the emergence of multidrug-resistant organisms in an era when drug development faces challenges causing pharmaceutical companies to curtail or abandon research on anti-infective agents, the use of combined existing antimicrobial agents may be an alternative. This study evaluated the effects of combining amoxicillin and chloramphenicol, to which many bacteria have become resistant, in vitro against Gram positive and Gram negative bacteria by agar diffusion, checkerboard and time-kill assays. The test isolates were susceptible to amoxicillin with minimum inhibitory concentrations (MICs) ranging between 0.448 and 500 µg/ml and between 1.953 and 31.25 µg/ml for chloramphenicol. Upon combining these agents, there was a drastic reduction in their MICs indicating an increased antibacterial activity that showed synergistic interaction against all the bacteria. At the highest concentrations, the inhibition zones ranges were 20.33-38.33±0.58 µg/ml for amoxicillin, 27.67-37.67±0.58 µg/ml for chloramphenicol and 31.67-39.33±0.58 µg/ml for the combined agents. The fractional inhibitory concentration indices (FICIs) showed synergy ranging from 0.129 to 0.312 while FICIs for additive interaction were between 0.688 and 1.0. There was no antagonistic interaction. At the 1/2MICs of the combined antibiotics, all the tested bacteria, except for Klebsiella pneumoniae ATCC 4352, Proteus vulgaris CSIR 0030 and Enterococcus cloacae ATCC 13047 were eliminated before 24 h. At the MICs, all the tested bacteria were eliminated except Enterococcus cloacae ATCC 13047 which was almost totally eliminated. Post-antibiotic assessment after 48 h showed that all the cultures were sterile except for that of Enterococcus cloacae ATCC 13047. The lack of antagonism between these antibacterial agents in checkerboard and time-kill assays suggested that combining amoxicillin with chloramphenicol can provide an improved therapy in comparison to the use of each antibiotic individually. The study indicates the potential beneficial value of combining amoxicillin and chloramphenicol in the treatment of microbial infections in clinical settings.

    Opis:
    Water eutrophication still causes many environmental and social problems, and so better quantification of the amount of nutrient loads discharged into surface waters is required. The basis for eutrophication analysis is data gathered in the frame of State Environmental Monitoring (SEM). In Poland, these measurements are carried out at the frequency of 6-12 times per year and serve as the basis for calculating the amount of nutrient input discharged to the sea. This article presents the results of the analysis of the representativeness of one measurement make two-hourly per day of the variability of total nutrient concentrations. For this purpose three cycles of field studies were carried out in accordance with plant growing season. The measurements were taken in November 2013, February 2014, and June 2014 in the Słupia River, at the site where it flows through the village of Charnowo (river profile). The analysis showed a significant change in the amount of total nutrient concentration during the day (up to 60% for total nitrogen and total phosphorus). This trend was maintained regardless of the stage of plant growth. Therefore, both the date for water sample collection and the time the measurement was taken become important for the subsequent evaluation of nutrient loads discharged into the sea. It is reasonable to assess the level of nutrient loads discharged into the sea not on the basis of a single measurement but based on the continuous registration of nutrients – this allows us to assign a daily average. It is also important from the point of view of the calibration of mathematical models, which are now an essential tool for analysing and forecasting environmental changes, and for which access to detailed data is very important.

    Aim. The aim of the survey was to find out how and why users of websites containing health information searched for information, how they feel about selected criteria for assessing the credibility of information, and what they are more likely to trust when they encounter a discrepancy between information from the website and from a doctor. Methods. An online survey of users of 4 health information websites, two of which are listed as trusted sites on MedLike. The respondents assessed 10 criteria for determining the trustworthiness of online information and websites by assigning a number of stars (5 stars = important). Results. The questionnaire was answered by 32,428 respondents (79.5% women, average age 47 years). The most frequently cited reasons for seeking information were their own health or illness (49%). Most respondents searched for information through an Internet search engine (66%). The importance of the criteria for selecting information did not differ significantly. The respondents gave the highest score (2.29) to the criterion of ease (I can easily find what I need). This was followed by consistency with information from the doctor (2.28). Conclusion. The respondents searched for information in the way described in the literature as most common (using a search engine) and tended towards a heuristic evaluation of online information and its sources (ease of information retrieval) and also appreciated if the information found concurred with information from a healthcare professional.

    Opis:
    Our research aims to reconstruct expert preferences regarding the visual attractiveness of furniture fronts made of pine wood using machine learning algorithms. A numerical experiment was performed using five machine learning algorithms of various paradigms. To find the answer to the question of what determines the expert’s decision, we determined the importance of variables for some machine learning models. For random forest and classification trees, it involves the overall reduction in node impurities resulting from variable splitting, while for neural networks it uses the Garson algorithm. Based on the numerical experiments we can conclude that the best results of expert decision reconstruction are provided by a neural network model. The expert’s decision is better reconstructed for more beautiful images. The decision for nice images is made based on the best 4 or 5 variables, while for ugly images many more features are important. Prettier images and those for which the expert’s decision is better reconstructed have fewer knots.

    The article presents an analysis of the results of a survey conducted in 2022 among students and young graduates of three vocational education courses, studying in EU countries (N = 428). The area of research concerns the awareness of competencies sought-after by employers and the self-assessed level of these competencies. The authors used tests of the equality of two means in order to check for differences in assessments according to the respondents' metric characteristics, and also factor analysis to check for similarities in attitudes towards different types of competencies in the respondents' assessments. Finding such similarities would allow to use a summative scale and reduce the dimensions.
    W artykule zaprezentowano analizę wyników badań ankietowych przeprowadzonych w 2022 r. na grupie uczniów i młodych absolwentów trzech kierunków kształcenia zawodowego pobierających naukę w kilku krajach unijnych (N = 428). Prezentowany obszar badań dotyczy znajomości kompetencji pożądanych przez pracodawców oraz samooceny poziomu tych kompetencji. Wykorzystano test równości średnich w celu sprawdzenia różnic w ocenach ze względu na cechy metryczkowe respondentów. Analizę czynnikową zastosowano dla sprawdzenia, czy w ocenach respondentów można zauważyć podobieństwo podejścia do różnych rodzajów kompetencji. Ewentualne stwierdzenie takiej prawidłowości pozwoliłoby na stosowanie skali sumacyjnej i redukcję wymiarów.
