W ostatnich latach można zaobserwować wzrastające zainteresowanie metodami systemowego zarządzania bezpieczeństwem w branży hotelarskiej, pomimo że nie ma obowiązku prawnego przygotowywania systemu zarządzania kryzysowego. Jest to spowodowane przede wszystkim rosnącym znaczeniem odpowiedniego poziomu jakości życia ludzi. Wynikiem tego są stale zmieniające się wymagania prawne, a także opracowania i ustanowienia norm określających wytyczne lub specyfikacje systemów zarządzania bezpieczeństwem. Skutecznie funkcjonujący system zarządzania kryzysowego wpływa na poprawę wyników ekonomicznych organizacji dzięki lepszemu niż dotychczas zarządzaniu procesami, w których może nastąpić zakłócenie ciągłości działania. Można uznać, że zarządzanie kryzysowe obejmuje swoim zakresem zintegrowanie celowo zaplanowanych przedsięwzięć organizacyjnych jak również logistycznych i finansowych, które mają na celu zapobieganie sytuacjom kryzysowym, zapewnienie sprawności struktur decyzyjnych na wszystkich szczeblach zarządzania oraz gotowości sił i środków do podjęcia działań, mających na celu reagowanie i likwidacje skutków powstałej sytuacji. Przedmiotem badań jest system zarządzania kryzysowego branży hotelarskiej i czynniki zewnętrzne go kształtujące. Celem badania jest identyfikacja systemu zarządzania kryzysowego i jego założeń, w kontekście zewnętrznym organizacji. Problem badawczy wyraża się w pytaniu: jakie czynniki zewnętrzne są kluczowe dla funkcjonowania systemu zarządzania kryzysowego w branży hotelarskiej? Próbą odpowiedzi na główny problem badawczy jest następująca hipoteza kierunkowa: czynniki ekonomiczne i prawne są kluczowe dla funkcjonowania systemu zarządzania kryzysowego w branży hotelarskiej. Na etapie zbierania danych zastosowano metodę sondażu diagnostycznego i technikę ankiety. Na etapie analizy danych zastosowano metody ilościowe (statystyki opisowe) oraz metody jakościowe (analiza danych tekstowych). Na etapie oceny danych zastosowano metodę sondażu diagnostycznego i technikę indywidualnego wywiadu pogłębionego (IDI). Wyniki badań ankietowych, jak również wyniki wywiadu eksperckiego potwierdzają, iż czynniki ekonomiczne i prawne są kluczowymi czynnikami zewnętrznymi wskazanymi przez przedstawicieli branży hotelarskiej. Jednakże, już przy określeniu, które z nich są pozytywne, a które negatywne pojawiają się w badaniu rozbieżne opinie.

In last few years, there has been a growing interest in systemic security management methods in the hotel industry, despite the fact that there is no legal obligation to prepare a crisis management system. This is primarily due to the growing importance of an appropriate level of quality of life for people. This results in constantly changing legal requirements, as well as the development and establishment of standards defining guidelines or specifications for safety management systems. An effectively functioning crisis management system improves the economic results of the organization thanks to better than before management of processes in which business continuity may be disrupted. It can be considered that crisis management includes the integration of deliberately planned organizational, as well as logistical and financial projects, which are aimed at preventing crisis situations, ensuring the efficiency of decision-making structures at all levels of management and the readiness of forces and resources to take actions aimed at reacting and eliminating the effects of the situation. The subject of the research is the crisis management system of the hotel industry and external factors shaping it. The aim of the study is to identify the crisis management system and its assumptions in the external context of the organization. The research problem is expressed in the question: what external factors are crucial for the functioning of the crisis management system in the hotel industry? An attempt to answer the main research problem is the following directional hypothesis: economic and legal factors are crucial for the functioning of the crisis management system in the hotel industry. At the data collection stage, the diagnostic survey method and survey technique were used. At the data analysis stage, quantitative methods (descriptive statistics) and qualitative methods (text data analysis) were used. At the stage of data evaluation, the diagnostic survey method and the individual in-depth interview (IDI) technique were used. The survey results, as well as the results of the expert interview, confirm that economic and legal factors are the key external factors indicated by representatives of the hotel industry. However, when determining which of them are positive and which are negative, divergent opinions appear in the study.

Internationalization is an inevitable phenomenon among all contemporary higher education institutions (HEIs) in a globalizing world. It is the driving force for development and progress. In course of the last 30 years, it became an inevitable element of HE management. However, it carries along a number of risks, pitfalls, and organizational challenges. To hedge those, quality assurance (QA) is called to the stage. HEIs therefore need not only to search for chances but also to increase the advancement of methods to safeguard the quality of education and research. It is for this reason that a discussion on the mutual evolution and impact of internationalization and QA is required, and this is the aim of this article to combine the issues dialectically. There are tools and institutions within the internationally and nationally developed QA concepts that have the potential and aim to secure the benefits of internationalization.

This research presents an experimental study carried out for the modeling and optimization of some technological parameters for the machining of metallic materials. Certain controllable factors were analyzed such as cutting speed, depth of cut, and feed per tooth. A dedicated research methodology was used to obtain a model which subsequently led to a process optimization by performing a required number of experiments utilizing the Minitab software application. The methodology was followed, and the optimal value of the surface roughness was obtained by the milling process for an aluminum alloy type 7136-T76511. A SECO cutting tool was used, which is standard in aluminum machining by milling. Experiments led to defining a cutting regime that was optimal and which shows that the cutting speed has a significant influence on the quality of the machined surface and the depth of cut and feed per tooth has a relatively small impact on the chosen ranges of process parameters.

A house or any other building without walls is truly hard to imagine. The first thing usually associated with walls is, of course, masonry. Today, masonry walls perform a load-bearing function in buildings up to four above-ground floors, in the higher parts of the buildings they perform a protective and stiffening function. However, there is a widespread opinion that the designer does not have to check the bearing capacity of masonry structures because masonry are were stand, are standing and will stand. Not everyone, however, currently works the wall as it should. The problem is that a lot of emphasis is now placed on reducing construction times. Therefore, there are a number of factors affecting the quality of the masonry structure, which overall reduce their safety. The article presents the influence of the quality of masonry on the differentiation of bearing capacity and reliability of an example masonry structure. The analyses included various values γm of the partial factor, recommended in the national annex PN-EN 1996-1, depending on the category of masonry units, class execution of works and type of mortar. In addition, a decrease in load capacity and reliability caused by the increase of the initial eccentric resulting from the inaccuracy of the masonry wall was examined.

Ciężko wyobrazić sobie dom, budynek bez ścian. Jeżeli myślimy o ścianach, to pierwszym skojarzeniem są mury. Dziś mury pełnią funkcję nośną w budynkach do czterech kondygnacji nadziemnych, w wyższych partiach budynków pełnią funkcję osłonową i usztywniającą. Powszechnie panuje jednak jeszcze opinia, że konstruktor nie musi sprawdzać nośności konstrukcji murowych ponieważ mury stały, stoją i stać będą. Nie każdy jednak obecnie mur pracuje tak, jak powinien. Problem polega na tym, że obecnie duży nacisk kładzie się na skrócenie czasu wznoszenia budynków. W związku z tym pojawia się szereg czynników wpływających na jakość wykonania konstrukcji murowej, które sumarycznie wpływają na zmniejszenie ich bezpieczeństwa. W artykule przedstawiono wpływ jakości wykonania muru na różnicowanie nośności i niezawodności przykładowej konstrukcji murowej. W analizach uwzględniono różne wartości współczynnika bezpieczeństwa, rekomendowanego w załączniku krajowym PN-EN 1996-1 [1], uzależnione od kategorii elementów murowych, klasy robót murarskich oraz rodzaju zaprawy. Ponadto zbadano spadek nośności i niezawodności spowodowany zwiększeniem mimośrodu początkowego wynikającego z niedokładności wykonania ściany murowanej.

The Ni-base superalloys are used in the aircraft industry for the production of aero engine most stressed parts, turbine blades or turbine discs. Quality of aero jet engine components has a significant influence on the overall lifetime of a jet engine as itself as well as the whole airplane. From this reason a dendrite arm spacing, grain size, morphology, number and value of γ' - phase are very important structural characteristics for blade or discs lifetime prediction. The methods of quantitative metallography are very often used for evaluation of structural characteristics mentioned above. The high-temperature effect on structural characteristics and application of quantitative methods evaluation are presented in this paper. The two different groups of Ni-base alloys have been used as experimental material: cast alloys ZhS6K and IN713LC, which are used for small turbine blades production and wrought alloys EI 698VD and EI 929, which are used for turbine disc production. Selected alloys have been evaluated in the starting stage and after applied heattreatment at 850°C for 24 hrs. This applied heat-treatment causes structural changes in all alloys groups. In cast alloy dendritic structure is degraded and gamma prime average size has grown what has a negative influence on turbine blade creep rupture life. Wrought alloys show partially grain boundary melting and grain size changed due to recrystallization what causes mechanical properties decreasing - ultimate tensile strength mainly.

This paper presents application of Data science models to the quality assurance processes at the university. In 2015 Narxoz University in Almaty, Kazakhstan introduced a major change to its academic policy. Final year bachelor students were required to complete team-based diploma projects, focused on solving real business problems, instead of writing standard, often purely descriptive and theoretical diploma theses. This article uses data science models (linear regression, logit and CART) to analyze the effects of this policy change on recent graduates’ employability and wage levels using results of telephone survey conducted among 1956 graduates in 2015 and 2016. Estimated models show that students who have firm plans to find jobs, acquire valuable competences when preparing bachelor diploma and actively participate in student life, have higher probability of employment and earn higher wages. It means that the process of writing bachelor diploma should be carefully designed and monitored and that student learning outcomes also depend on their extra-curricular activity. Such analysis provides deep and interesting insights into the learning and assessment processes and should be a part of annual quality assurance review in every university. For example, results indicate that grading practices at Narxoz require a major review, as graduates with higher GPA did not exhibit higher employability nor higher wages. Similarly, curricula of some specializations (majors) should be reviewed due to low employment rate of graduates. Appropriate changes have already been implemented at Narxoz in 2017. Finally, we found that economic shocks have much stronger short-term impact on recent graduates’ employability and wages than reforms of academic curricula.

High quality is organizations’ competitive advantage. It is beneficial to base this on professional approach, and basic concepts and definitions with scientific foundation. The necessary main concepts consist of quality, quality management, quality improvement and quality assurance. Organizations' top management is responsible of the quality management decisions and implementations. The present practical situation is fragmented and the implementations are most often based on the instrumental means of the different methodological schools, which is confusing and detrimental to the understanding and usefulness of the concept of quality management. It is not beneficial to build a special system for quality management by only following the requirements of the general standard. This cannot ensure competitive business advantage. In this article, we present an alternative approach that is a natural practical way to realize quality management as the teleological solution, Quality Integration, in which the general and specific quality concepts, principles and methodology are embedded within the normal business management activities. Our Quality Integration is based on the thinking of organizational learning. Its framework covers both running the current business and improving the overall business performance. This model has been used as the thinking framework in practical organizational cases since 1990’s. As the business circumstances change constantly, the organization must be constantly ready to renew through both small and radical changes. This change also receives resistance, and the development takes place according to a multi-phase process towards the new integration and requires a proper recognition and decisions. Principles of the organizational learning can help organizations in a consistent way. Evaluation of the overall organizational performance is an important quality management practice and should take into account performance enablers (processes) and also the results obtained thereof. In our approach, the evaluation criteria emphasize organizational learning and integration. The external context of the organization has a crucial role in achieving and developing the business objectives. The organization’s strategy can no longer be based on the value chains but on finding ways to alter them radically through value networking. The organization is influenced by the true and all-inclusive reality, which differs from the apparent reality perceived by the senses, and which is only revealed through consciousness. Understanding this reinforces awareness and trust that are important factors also in quality management and quality assurance.

W wyniku spawania mogą pojawić się nieszczelności, które znacząco obniżają wytrzymałość złączy spawanych, a ich małe rozmiary mogą uniemożliwić ich wykrycie. Z punktu widzenia szczelności połączenia oraz jego trwałości eksploatacyjnej jest to cecha niepożądana. W celu wykrycia nieszczelności stosuje się badania nieniszczące szczelności, wśród których można wyróżnić jedną z najbardziej popularnych metod, a mianowicie badania szczelności metodą penetracyjną. Jest to metoda, która bazuje na metodzie penetracyjnej wykrywającej niezgodności powierzchniowe. Po oczyszczeniu złącza nanosi się w pierwszej kolejności wywoływacz od strony lica spoiny, a po odparowaniu cieczy nośnej należy nanieść penetrant na przeciwległą powierzchnię.

In the work, leak testing by penetrant method tests were carried out using the AlMg5 aluminum alloy method with plates simulating slits from the above-mentioned material. The tests were aimed at checking the influence of individual factors, such as the fracture depth, the position of penetrant application and the number of applications for developing time. The research was based on the measurement of development time depending on the set factors influencing this process. The dependencies determined allow the estimation of the minimum development time to detect leaks in the penetration method. Information in this field should make it easier to make decisions about the release of a product into service or its repair.

The recently developed technology of twin-roll-cast (TRC) magnesium strips permits an efficient production of magnesium sheets, primarily for the automotive industry. The focus of the paper is to develop a structural equation model explaining the variance of the thickness profile formation. Hence, the complex and partially unknown relationships between twin-roll casting process parameters and the thickness profile formation are analyzed using latent variables, e.g. the deformation resistance, length of contact arc, etc., which consist of several observed parameters. The fundamental process variables and their effect on the thickness profile formation during twin-roll casting are investigated and evaluated by partial least squares structural equation modeling (PLS-SEM) – a statistical method that fits networks of constructs to empirical data. The results of the predictive modeling technique allow an approximation of the existing interrelationships between thickness profiles, rolling force as well as processes in the roll gap which are typically difficult to measure directly using sensors. In this context, it was identified that the thickness profile variation is primarily caused by the forming force, which is mainly driven by the length of contact arc. Moreover, implications for the control of the thickness profile are derived.
