Opis:
Subject and purpose of work: This paper aims to assess the operational efficiency of public higher vocational schools in the Lublin Region. Materials and methods: The assessment was based on the non-parametric method of data envelopment analysis (DEA) using the standard CCR-O model. Results: In most of the analysed models (E, N, O series), the public higher vocational schools in the Lublin Region were found to have improved their efficiency in 2019 relative to 2017. Conclusions: E-series models are very susceptible to changes, both in terms of inputs and effects. This gives the possibility of a significant impact on the increase in the assessment of the effectiveness of investigated units DMUs. N-series models demonstrate the importance of aggregation and quality of source data for the results of performance assessment. Class O models justify the need to look for and compare the use of other DEA model variants in the study of the effectiveness of public higher vocational schools.
Przedmiot i cel pracy: Celem opracowania jest ocena efektywności funkcjonowania publicznych uczelni zawodowych z regionu województwa lubelskiego. Materiały i metody: Do opracowania materiału zastosowano nieparametryczną metodę DEA (ang. data envelopment analysis) w standardowym modelu CCR-O. Wyniki: W większości analizowanych modeli (seria E, N, O) odnotowano poprawę oceny efektywności badanych państwowych wyższych szkół zawodowych regionu lubelskiego w 2019 roku w stosunku do 2017 roku. Wnioski: Modele klasy E są bardzo podatne na zmiany, zarówno w obszarze nakładów, jak i efektów. Daje to możliwość istotnego wpływu na wzrost oceny efektywności działania badanych jednostek DMU (ang. Decision Making Unit). Modele serii N wykazują istotność kwestii agregacji i jakości danych źródłowych dla wyników oceny efektywności. Modele klasy O uzasadniają konieczność poszukiwania i porównywania zastosowania innych wariantów modelu DEA w badaniu efektywności publicznych uczelni zawodowych.

latent profile factor analysis model ordered categorical data
Opis:
In the literature factor analysis is admittedly a well-known and effective multivariate method in the reduction of extensive and broad data, e.g., in the analysis of too many variables. It is also known for the process of unidimensional or multidimensional scale/s construction. Typically, in many studies (especially those pertaining to market research area) a common factor analysis solution is used (based on continuous data). However, there are rarely ever undertaken studies pertaining to latent variable models where other type of data is used based on discrete variables. One of these models might be called Latent Profile Factor Analysis - LPFA. In this article author’s main objective is to propose and discuss its (LPFA) main assumptions. In order to prove the model’s functionality in practice of market research, a brief example of LPFA model for ordered categorical data (based on one-factorial solution) in reference to hedonic consumption data is given at the end of the paper.

The aim of this article is to evaluate the technical efficiency of the chosen commercial banks, which in the years 2014–2016 were participants in acquisitions in the banking sector, with the usage of the Data Envelopment Analysis (DEA) model. The DEA model was modified through reshaping the linear form using the Charnes, Cooper, and Rhodes (CCR) model, which is aimed at expenditures. Particular attention was paid to the impact of acquisitions in the banking sector on the improvement or deterioration of the technical efficiency of banks that act as acquiring banks.

Opis:
A plate-cavity coupling method based on modal expansion technique in the closed sound cavity was introduced, aiming at ship cabin structural noise. Using this method, a coupled equation was established. The structural vibration acceleration of the target cabin was extracted from a ship vibration response calculation, applied to the model. Then the target cabin noise value was obtained through numerical calculation. The effectiveness and reliability of the method were validated through experiments. The coupled model predicts noise in the cabin does not require fluid finite element model of the cabin air, thus greatly reducing the calculation time compared with the pure finite element method. It was shown that the method is suitable for the calculation of noise in a single ship cabin; the method has a high calculation efficiency. Furthermore, the calculated result is a continuum. On the one hand, it can be conveniently converted to an octave or 1/3 octave according to the specification. On the other hand, the form of the continuum also provides a corresponding response to the subsequent vibration and noise control.

Opis:
With rapid economic development and industrialization, air pollution is becoming a critical global issue affecting health. Sulfur dioxide and nitrogen oxides are the major contributors to acid rain and the key indicators for evaluating atmospheric pollution. And source intensity and meteorological factors are the main ways to influence the concentrations of sulfur dioxide and nitrogen oxides. Thus, to investigate the specific effects of source intensity, temperature, humidity, wind speed and atmospheric pressure on SO2 and NOx, the path analysis method was used for the model. The results showed that Source intensity significantly affects the concentrations of SO2and NO2. For both NO2 and SO2, the source intensity accounted for around 40%. Meteorological factors have very limited effects on the concentrations of SO2and NO2. The effects of the meteorological factors on air pollutants are specific as differences in material properties. Humidity significantly affects the concentration of SO2while temperature, humidity and wind speed have significantly affected the concentration of NO2.

Opis:
Celem pracy jest prezentacja modelu hazardów proporcjonalnych Coxa(ang. Cox proportional hazards model), charakteryzujących go własności oraz metod esty-macji jego parametrów. Znajduje on zastosowanie w analizie przeżycia przy przewidywaniuszans przetrwania pewnych obiektów (najczęściej pacjentów w badaniach medycznych).Istotną zaletą modelu jest możliwość uwzględnienia w nim danych niepełnych, które częstopojawiają się w przeprowadzanych badaniach — zarówno w sposób losowy, jak i celowy.Model Coxa sprawdza się szczególnie dobrze w sytuacji, gdy interesujące jest określenieskuteczności sposobu leczenia w sensie porównawczym, czyli w odniesieniu do innych te-rapii. Terminologia i przykłady zaczerpnięte są na ogół z medycyny, ale opisany modelstosuje się również np. w socjologii, kryminalistyce czy inżynierii.Słowa kluczowe: model Coxa, hazard, analiza przeżycia.
The paper presents Cox proportional hazards model, its properties and methods of its parameters estimation. It is widely applicable in survival analysis – in prediction of survival chances of some objects (usually patients in medical studies). The essential advantage of the model is allowing of incomplete data, which often appear in studies –both in random and fixed way. Cox model works especially well when determination of treatment effectiveness in comparative sense (with reference to other therapies) is needed. Terminology and examples are usually taken from medicine but the model can be used also in sociology, crime detection or engineering.

Opis:
Analysing the banking business model as a supervisory perspective is a new way of monitoring the actions of supervised institutions, which significantly increases control. An additional analysis of banking business models can supply useful tools for understanding the nature of risks related to a given banking business model, and its influence on systemic risk. These tools are useful to market participants and regulation and supervisory institutions. The main goal of this article is an identification of contexts and conditions of the banking business model as a supervisory perspective. This approach allows to perceive its characteristics, aims, and methodology requirements. The supervisory perspective on business models was also compared to other practical and theoretical approaches, creating analytical context. An analysis of European guidelines for business models as a supplementary supervision practice, and their implementation in Poland was performed as well

Opis:
A high number of examples in today’s global industry prove that it is difficult to ensure a certain level of quality. One possible reason is the increasing complexity of modern mechatronic product systems. Interface problems due to several involved science disciplines and the lack of understanding subsystems, which are delivered by different suppliers, make it difficult to identify critical components and specifications of elements. Furthermore, it is even harder to estimate the effects of elements because of their unknown dependencies and relations. Therefore it becomes more and more improbable to develop a safe, sustainable and high quality product right from the beginning. In order to understand failures in complex system structures today’s engineering industries need a generic approach that increases the understanding of systems, identifies critical components and considers the different levels of a system. It shall examine failures that cause system errors but also failures that limit system functions. Thus, it is necessary to model and simulate the causally failure chains and analyse over several system levels and elements with their dependencies. This leads to a better understanding of the whole picture of cause and effect. This research paper points out which requirements this new model-based approach has to fulfill and how it is possible to link quality and reliability methods to achieve an overall understanding and analysis of a complex system to assure high quality and sustainability.

In this paper, we propose a new formal model to describe risk analysis and measurement process for IT systems. Our model complies with international standards and recommendations for non-profit organisations. The model accounts for solutions used in widely known and recommended risk analysis methods and provides for evaluation of efficacy of these solutions. A simple example illustrates the application of the proposed model for effective risk analysis of any IT system.

Opis:
This paper presents the possible development scenario of the Polish agricultural sector till 2020. It also assesses the impact of macroeconomic growth, CAP reforms and worldwide policies towards the agriculture on this development. The scenario is build using an extended version of the Global Trade Analysis Project model GTAP which is a computable general equilibrium model of the world economy. The analysis shows that the growth of Polish agri-food sector observed after accession to the European Union will be prolonged in the future and will lead to an increase of agrifood sector incomes. However, it is expected that the positive trade balance in agri-food products will decrease significantly in consequence of the world trade liberalization and the EU policy stimulating biofuels production.

Technology advancement has seemingly made the world smaller, especially with the existence of tools such as a cell phone. Along with this development, new method of marketing and promotion has been formed. One of these strategies is the use of micro cinema. After suffiient background study on the factors that seemed to affect the effectiveness of micro cinema, these factors were then used to study the response by Taiwanese students and a working group as well as the working group from Mainland China. Responses obtained from all groups were then analyzed using grey relational analysis (GRA) and then further analyzed using the modifid dramaturgy model by Grove et al. (1992). The result obtained can be used to represent the important factors in micro cinema affecting each group.

Opis:
In this paper, a new dynamic model for the vibration analysis of an inwardoriented rotating cantilever beam with extra distributed mass was presented. The derived differential equation of motion was solved using the meshless methods of generalizedMultiquadric Radial Basis Function (RBF) and the eigenfrequencies of the system were determined. The same problem was also modeled using the finite element method and the results were compared to validate the accuracy of the proposed model. Later, the effect of the partially distributed mass amount and location on the eigenfrequencies was studied for various beam lengths. The results showed that the eigenfrequency at a constant rotational speed mostly decreased unless the mass was located at the free end of the beam. The location of the mass had a greater effect on the first eigenfrequency compared to the second and third eigenfrequencies. A joint dimensionless eigenfrequency was found at a specific rotational speed regardless of the distributed mass. Nearly constant dimensionless eigenfrequencies could be obtained for a wide range of rotational speeds by adjusting the distributed mass.
