Opis:
Zastosowanie nowych technologii w Przemyśle 4.0 umożliwia lepszą organizację, monitorowanie, kontrolę oraz skuteczną optymalizację procesów produkcyjnych, szczególnie w zakresie wydajności. Prezentowane rozwiązanie opiera się na hierarchicznej analizie wskaźników efektywności, w tym głównie na kontroli wskaźnika ogólnej efektywności zasobów produkcyjnych OEE. Rosnąca liczba możliwych do uzyskania skwantyfikowanych sygnałów monitorujących pracę maszyn, temperaturę otoczenia czy częstotliwość drgań sprawia, że narzędzia wspomagające decyzje są coraz bardziej wyrafinowane i, poza prezentacją obecnego stanu zasobów, coraz częściej obejmują także analizę predykcyjną. Opisywane narzędzie PUPMT pozwala zidentyfikować kluczowe zdarzenia, które mają istotny wpływ na bieżącą lub przyszłą efektywność produkcji. Umożliwia także analizę typu what-if, dopuszczając symulację wpływu projektowanych zmian, a wyniki tej symulacji uzależnia od skutków podobnych zmian, które miały miejsce w przeszłości w danym przedsiębiorstwie. Dzięki automatycznej identyfikacji potencjalnych zależności rozwiązanie dostosowuje się do specyfiki firmy lub wybranej jednostki produkcyjnej. Początkowe rozdziały zawierają m.in. opis najważniejszych metod wykorzystywanych w rozwiązaniu PUPMT. W dalszej części przedstawiono wybrane wyniki badań przemysłowych, które przeprowadzono na kilkudziesięciu jednostkach produkcyjnych.
The use of new technologies in Industry 4.0 enables better organization, monitoring, control and effective optimization of production processes, especially in terms of efficiency. The solution is based on a hierarchical analysis of key performance indicators, including mainly the control of Overall Equipment Effectiveness (OEE). The growing number of quantifiable signals monitoring machine operation, ambient temperature or even the frequency of vibrations makes decision support tools more and more sophisticated. Moreover, they also include predictive analysis in addition to presentations of the current state of resources. PUPMT tool allows identifying key events that have a significant impact on current or future production efficiency. It also allows the what-iftype analysis, running the simulation of the impact of the proposed changes, and the results of this simulation depend on the effects of similar changes that occurred in the past in a given enterprise. Thanks to the automatic identification of potential dependencies, the proposed solution adapts to the specifics of a given company or even a selected production unit. The paper in the first part contains a description of the essential methods used in the PUPMT tool. The second part presents selected results of industrial research, which were carried out on several dozen production units.

Opis:
Purpose: The article presents the concept of profiling a website. Profiling is focused on the quality of the SEO (search engine optimization) audit and the conclusions that flow from it, and its goal is to increase the effectiveness of the review. The primary purpose of the work was to assess the accuracy of the characteristics prepared in this way. Design/methodology/approach: Four websites related to the hotel industry have been profiled and compiled in pairs, whose addresses were obtained from an Internet search engine. The tests were performed using selected testing tools. Findings: It has been shown that based on an analysis of SEO attributes, one can create a technological profile of a site without browsing it first, and the relevance of profiling is determined by two factors: the auditor’s experience and audit scope, including the quality and number of testing tools used. Practical implications: The idea of profiling involves looking at a website only through the prism of an SEO audit, which changes the perspective and forces a more in-depth analysis of SEO tests. This can contribute to better use of information obtained during an inspection. Profiling is often treated as an activity supplementing an SEO audit in the case of a lack of access to testing tools when the test results are incomplete, insufficient, or inaccessible. Originality/value: By analyzing SEO attributes, one can create a technology profile and a specific site characteristic without browsing it first. Two factors determine the relevance of profiling: the auditor’s experience and the quality and scope of the audit performed by the testing application.

Purpose: The subject of the research were the logos of individual facilities of rural tourism in Poland found on the websites of these facilities. Design/methodology/approach: The research covered 243 websites hosted on paid domains. A semantic, formal and aesthetic analysis of graphic signs was conducted. The research was conducted by way of exploratory method. Logos were found on 202 websites. 41 facilities did not use a graphic sign. In 112 cases the logo was composed of a symbol and logotype. Findings: In 147 cases the logos had a traditional form (traditional, neutral, rustic) or used elements associated with rural areas. In 49 cases, the logos were assessed as modern. Originality/value: What was noted was the fact that in hyper-text documents, logos perform numerous functions. Apart from making the navigation easier, they can also have a dynamic, multimedia form. On the basis of analysis of graphic signs, two main types of rural tourism facilities were distinguished: “traditional” and “commercialized” ones.

Opis:
Purpose: Interactivity and simplicity of navigation make users browse a website, and its usefulness is the main factor which influences the intention of using it to buy a product or service. The aim of the paper was to identify the most frequent project errors that negatively impact the usability of websites of agortourism farms. Design/methodology/approach: The surveys were carried out by the audit method in a set of websites which were grouped according to accepted categories. The audit was based on a heuristic analysis using a control list. Findings: A number of usability problems have been identified in the set of examined websites; however, the most important were the lack of explicit updates or the presentation of outdated information, as well as the dysfunction of forms – contact and inquiry. Zero-category sites are unusable. They are characterised, among others, by no visible updates (or presentation of outdated information), archaic technique of execution, often based on so-called “Frames” (iframes) or tables, as well as imperfect, archaic graphic design. Originality/value: The usefulness of a website (reflected in the design details) goes into the background when it only serves an information and contact function and does not provide advanced functionalities, such as, for example, an accommodation booking form. In the case of agrotourism farms, the most important elements are the thematic graphic design and exhaustive content.

Opis:
In the autumn of 2016 a geomagnetic survey was conducted in Skołoszów, site. 7, Dist Jarosław. The magnetic prospection took place on a low hill spanning 2.12 ha in total. Distribution of the anomalies, as visible on a map depicting obtained data, reflects numerous structures related to human activity in the area during the prehistory and historic times. Among them are two features interpreted as residues of funerary rituals taking place at the site. One of them pertains to Middle Neolithic earthen long barrow, whereas the second by its shape resembles Late Neolithic/Early Bronze Age tumuli. Apart from the latter, one can discern numerous anomalies potentially related to pits and ditches. Interpretation of the geophysical imagery was based upon the results of excavations conducted in 2010 in the nearby section of Skołoszów, site 7. In the process, funeral structures in the types of earthen long barrow and a presumable tumulus were recorded. Thus, it is possible to confront observations inferred from the results of non-invasive, magnetometric survey, with data obtained by means of more direct exploratory methods. Besides the prehistoric record, our investigation resulted in reconstruction of the trenches most probably dating to the First World War.

Opis:
Interactive data visualisations are popular and come in different forms, from static raster files to dynamic and complex proposals. The usability of the applications can be increased through the improvement of their technical attributes such as a reduced number of external components or image file compression. The objective of the paper is to analyse the correlation between raster compression and the performance of a map application. The research involved an application created specifically for this purpose. Raster compression and performance were measured using selected online tools. Raster compression has been demonstrated to enhance map application performance, although not all performance indicators improved.

Opis:
There are many techniques available today for publishing maps in web browsers. The material is often created using geographical information systems (GIS). The performance, most often understood as the speed of loading the application into a web browser, is the determinant of the viewing experience. The performance of a map application can be improved through such process as minification. The purpose of the study is to measure the impact of minification on the performance of the map component. Code minification was performed by selected web applications. The performance of two applications, GTmetrix and Dareboost, was tested. Two research questions have been posed: RQ1: How great a reduction in the size of component files of an application can be achieved with minification? and RQ2: How will the minification affect the performance of a web browser map application? The research has shown that the model applications were performing relatively poor, in particular, on mobile devices. The minification reduced the size of HTML, CSS, and JavaScript files by about 11%, which had a slight impact on application performance (in the employed research design). It has been demonstrated that minification was insufficient for improving significantly the performance of the tested applications. Additional compression of image files is recommended.

Opis:
This article is the result of the latest studies on the settlement of the Funnel Beaker culture communities in the loess area of the Rzeszów Foothills and the Lower San Valley. It deals with shaping of the settlement network of this cultural phenomenon in relation to the local natural environment, chronological issues (initiation, duration and deconstruction of the phenomenon) and intercultural contacts. Analysing the sources it was found that in the studied area, the communities of the Funnel Beaker culture formed characteristic settlement clusters, strongly related to the network of river valleys crossing the loess patch of the Rzeszów Foothills and the Lower San Valley. Within such clusters there were functionally diverse sites such as: cemeteries, various size of settlements and camps. In the light of the latest data in the field of absolute dating and information coming from ceramics, it can be assumed that the appearance of these communities in the discussed area occurred slightly earlier than about 3700 BC. Their development did not take place in isolation from neighbouring “worlds”. In many local settlements of the Funnel Beaker culture the ceramics were recorded, which may provide evidence of contacts with the eastern environment of this culture and the late Tripolye culture.

Opis:
Koncepcja długiego ogona wyszukiwania zakłada, że nietypowe, mało popularne słowa kluczowe oraz szczegółowe i wielowyrazowe zapytania, których jest bardzo wiele, generują większość ruchu na stronie internetowej. Celem pracy było wykazanie możliwości zastosowania strategii długiego ogona w zwiększaniu zasięgu oddziaływania witryn internetowych obiektów turystyki wiejskiej. Analizie poddano widoczność witryn internetowych w wynikach wyszukiwania. Następnie przeprowadzono audyt stopnia optymalizacji dla wyszukiwarek oraz audyt treści wyszukanych witryn, a także zweryfikowano siłę zależności występujących pomiędzy miejscem witryny w wynikach wyszukiwania, a jakością witryny oraz wielkością (rodzajem) obiektu turystyki wiejskiej. Wykazano, że w tekstach publikowanych na stronach internetowych obiektów turystyki wiejskiej należy wykorzystywać zarówno zwroty ogólne, jak i złożone.
The concept of a long search tail assumes that unusual, less popular key phrases and detailed and multi-word phrases, of which there are many, generate the majority of traffic on the website. The purpose of the work was to demonstrate the legitimacy of using a long tail strategy in increasing the range of impact of websites of rural tourism facilities. The visibility of individual websites of rural tourism facilities in the search results was analyzed. Then, an SEO audit, and an audit of the content of the searched websites was carried out, as well as the dependence between the site’s place in the search results and the quality of the website and the size (type) of the rural tourism facility were verified. The research has shown that both general and complex phrases should be used in the texts published on websites of rural tourism facilities.

The aim of this article is to present the latest results of geophysical researches executed in April 2017 at the site Gordineşti II-Stînca goală in northern part of the Republic of Moldova. Based on very intriguing discoveries (i.e. remains of a dwelling, part of a clay platform and one pit) during the excavations carried out in 2016 and earlier, it was decided to investigate a larger area using non-invasive geophysical method. As a result, a few types of anomalies of different shapes were identified. It seems that these anomalies indicate the occurrence of remains of the dwellings as well as hypothetical main square between them in the centre of this fortified settlement

Opis:
In the 1950s, a settlement of the Funnel Beaker culture (FBC) was discovered on the Lysivka Hill in Vynnyky (Fig. 1), located in the centre of the West Ukrainian territory of this culture (Hawinskyj, Rybicka 2021). Currently, it belongs to a small group of FBC sites in Western Ukraine that have been excavated. The information presented by M. Peleshschyshyn, who conducted excavations in Vynnyky-Lysivka, regarding the relationship between the FBC community and the Tripolye culture (TC) was particularly interesting (see Rybicka 2017). He believed that Vynnyky recorded the coexistence of their population (Peleshschyshyn 1998a, 191). The burnt daub clusters discovered at that time could probably have been the remains of dwellings. The aim of the research carried out since 2016 was to verify the hypotheses of M. Peleshschyshyn (1998a) in the context of the FBC-TC relationship (Hawinskyj, Rybicka 2021) and to establish the date of the settlement usage in Vynnyky-Lysivka. Radiocarbon dating obtained for the samples from the features from the northern zone of the settlement, allow the researchers to be placed Vynnyky-Lysivka in the period 3500–3360 BC and synchronized with the third phase of the southeastern FBC group.

Opis:
The success of a rural tourism business largely depends on promotional activities. Having developed a tourist product, owners of rural tourism facilities should therefore inform the buyers about it. Usually, they rely on websites and social media for this purpose. However, for a website to fulfill its function, it should be of high quality. The improvement of website quality can be achieved through measures which include search engine optimization (SEO) and content and graphics optimization. The purpose of this paper is to assess the potential of image optimization on websites of Polish rural tourism facilities. The research covered 1000 paid domain websites. The largest part of the sites surveyed were rated good in terms of graphic file optimization. In spite of this, it was possible to reduce the size of graphic files covered by this study and used in the research model by as much as 67% without significantly deteriorating their quality. This research showed that image optimization has no direct impact on the outcome of an SEO audit, and that images can be optimized even for websites with high final scores.
