Authors: Rónay Zoltán , Antonowicz Dominik , Jaworska Marta 
Published: August 2020

Absztrakt:
A tanulmány két viszonylag új felsőoktatási reformot vizsgál Lengyelországban és
Magyarországon. Mindkettő egyfajta board (felügyelő testület) bevezetésére
irányult különböző elnevezéssel. Az összehasonlító tanulmány alapja a két ország
közös (kommunista) múltja, földrajzi helyzete (kelet-közép-európai térség) és a
humboldti egyetemi modell öröksége. Az elemzés a reformok előzményeinek
bemutatása után magát a két nemzeti reformot vizsgálja, megvilágítva a
különbségeket és hasonlóságokat a lengyel egyetemi tanács és a magyar
konzisztórium felépítése, hatásköre és felelőssége, valamint az egyetemi
autonómiához való viszonya tekintetében. Ezzel is hozzá kíván járulni a
boardizmusról jelenleg folyó szakmai diskurzushoz, értékelvén annak bevezetését
e két (hasonló) nemzeti felsőoktatásban.

Authors: Saleem Mohammad , Kovari Bence 
Published: August 2020

Abstract
Amongst different approaches, dynamic time warping has shown promising results during the online signature verification competitions of previous years. To improve the results of dynamic time warping, different preprocessing steps may be applied and different dimensions of the samples may be compared. The choice of preprocessing steps and comparing dimensions may significantly influence the results. Thus, to aid researchers with these decisions, a comparison made between the results of promising preprocessing algorithms as horizontal scaling, vertical scaling and alignment using dynamic time warping in different dimensions and their combinations on two datasets (SVC2004 and MCYT-100). The results showed that preprocessing methods made a very promising improvement in the verification accuracy.

Acoustical aspects of the reconstruction of a historical building with closed courtyard
Authors: Horn Valéria V. , Dudas Annamaria 
Published: August 2020

Abstract
The Szentgyörgyi-Horváth-house is one of the major historical buildings of Balatonfüred. The design of the reconstruction was preceded by detailed architectural historical study. The reconstruction of the building was realized by retaining the original structures. For the new function the building was equipped with an air-conditioning engine-room. The air conditioner is a significant source of noise for the apartments facing the courtyard of the building, due to its continuous operation. The acoustic examination of the enclosed yard was calculated with two different approaches. The distance-dependent approximation, which is usual for large halls, was approved. Building construction structures were determined based on the results to meet the acoustic requirements.

Published: August 2020

Abstract
Ensuring the provision of suitable living units remains one of the most challenging issues among the architects. The economic conditions in Kosovo represent one of the factors that influenced the functional and spatial change in multi-apartment buildings. Taking into account the passing of time, economic conditions, the requirements and needs of the communities change, those affects change in the functional and spatial aspect. The construction of multi-apartment and individual buildings, as well as other buildings with other uses in the center of the cities represents a delicate issue. On the other hand, the need for reconstruction and re-destination of usage of the existing residential buildings is becoming an important topic for the society in Kosovo. The issue is somewhat sensitive regarding the multi-apartment residential buildings, given that the usable surface is increasingly limited. The next challenge for the architects will be the treatment of the existing areas, their adaption in harmony with the requirements of the new generations, social changes that Kosovo is dealing with. The entire endeavor to reach a more comfortable solution is realized through treatment of the residential spaces not only in function wise, as well as in the exterior, through the transparence in architecture. The aim of the paper is to show transformation of the living spaces through real example, in Prishtina.

Published: August 2020

Abstract
The modeling of soil erosion processes is affected by several factors that reflect the physical-geographic conditions of the study site together with the land use linkage. The soil parameters are significant in the modeling of erosion and also runoff processes. The correct determination of a soil's parameters becomes a crucial part of the model's calibration. This paper deals with a sensitivity analysis of seven soil input parameters to the physically-based Erosion 3D model. The results show the variable influence of each soil parameter. The Erosion 3D model is very sensitive to initial soil moisture, bulk density, and erodibility.

The main findings of the present study that, the Los Angeles index and water absorption of crushed aggregate is affected by the coarse recycled concrete aggregate dosage in its parent concrete, as well as, incorporating cement replacing materials in parent concrete help to enhance the abrasion resistance of crushed aggregate.
Seismic retrofit of steel frame structures
Authors: Ismail Magdy 
Published: August 2020

Abstract:Moment resisting frames are considered as an effective seismic force resisting system that is used for steel structures. Some of these structures that were built in high seismic hazard zones were designed according to old strength-based design codes. Currently, these structures do not meet the requirements of the new seismic codes. Therefore, the seismic retrofit of these structures is mandatory and cannot be overlooked. Steel braces and concrete-steel composite elements are common solutions for enhancing the seismic behavior of existing steel frame structures. This paper presents a numerical study that evaluates different possible techniques for the seismic retrofit of existing steel moment-resisting frame structures. The study investigates the performance of three multi-story buildings with different heights that are located in a high seismic hazard zone. Three retrofit techniques were introduced including; 1) X-Steel braces, 2) buckling restrained composite braces, and 3) composite concrete-steel plate shear walls. The seismic performance enhancement of the studied structures was evaluated in terms of the structure’s fundamental period, maximum inter-story drift and maximum base shear-to-weight ratios. Moreover, the cost of retrofitting material was estimated for each technique and they were compared to select the retrofit technique with the least constitutive material cost.

Abstract:During sketch design stage for the new block of the University of Pécs, Medical School comfort and lighting simulations were applied to quantify optimization strategies. Simulation cases about shading possibilities, façade glazing ratios and internal heat storage masses evaluate the impact of illumination, solar gains, loads and heat transmission on visual and thermal comfort. The goal was to select the most favorable comfort, coupled with maximum reduction of investment costs. Concepts represent 14% (shading), 10% (reduced wall-window ratio), 11% (slabs without suspended ceilings), and 17% (combined wall-window ratio and thermal mass) improvement in thermal comfort performance, and it was proposed for further design.

Published: August 2020

Abstract:Day-lighting studies in buildings play a major role in indoor environmental investigation and can be conducted at the early stages of building design. Window position significantly affects day-lighting performance. This paper assessed the impacts of the window position on the visual comfort through two main factors; daylight factor and light uniformity in the hot and dry climate zone. In this study different window positions have been examined to achieve optimal visual comfort, using a dynamic simulation through Vi-suit plugin for Blender 3D software that controls the external application Radiance software. The results revealed that the window position at sill start from 1.4 m of a room characterized by (4.30 m × 3.00 m × 3.00 m) is the best compromising solution that complies with the daylight factor and light uniformity standards in the indoor environment. The findings of this study provide a more detailed and comprehensive analysis of the window design for architects/designers in the early building design stages in the hot and dry climate region.
On smooth approximation of probabilistic criteria in stochastic programming problems
Authors: Sobol Vitaliy , Torishnyi Roman 
Published: August 2020

In this paper we study one of the possible variants of smooth approximation of probability criteria in stochastic programming problems. The research is applied to the optimization problems of the probability function and the quantile function for the loss functional depending on the control vector and one-dimensional absolutely continuous random variable. In this paper we study one of the possible variants of smooth approximation of probability criteria in stochastic programming problems. The research is applied to the optimization problems of the probability function and the quantile function for the loss functional depending on the control vector and one-dimensional absolutely continuous random variable. The main idea of the approximation is to replace the discontinuous Heaviside function in the integral representation of the probability function with a smooth function having such properties as continuity, smoothness, and easily computable derivatives. An example of such a function is the distribution function of a random variable distributed according to the logistic law with zero mean and finite dispersion, which is a sigmoid. The value inversely proportional to the root of the variance is a parameter that provides the proximity of the original function and its approximation. This replacement allows us to obtain a smooth approximation of the probability function, and for this approximation derivatives by the control vector and by other parameters of the problem can be easily found. The article proves the convergence of the probability function approximation obtained by replacing the Heaviside function with the sigmoidal function to the original probability function, and the error estimate of such approximation is obtained. Next, approximate expressions for the derivatives of the probability function by the control vector and the parameter of the function are obtained, their convergence to the true derivatives is proved under a number of conditions for the loss functional. Using known relations between derivatives of probability functions and quantile functions, approximate expressions for derivatives of quantile function by control vector and by the level of probability are obtained. Examples are considered to demonstrate the possibility of applying the proposed estimates to the solution of stochastic programming problems with criteria in the form of a probability function and a quantile function, including in the case of a multidimensional random variable.

Published: August 2020

Lifetime use of IgG replacement therapy is the standard of CVID treatment. However, full control over stabilization of chronic infection loci is not always achieved, even if this therapy is continuously applied. The purpose of this study was to carry out comparative analysis of changes in cellular component of adaptive and innate immune response, depending on effectiveness of replacement therapy of patients with infectious CVID phenotype. The observation group consisted of 15 patients with CVID who were diagnosed since early childhood in 100% of cases. They had prolonged respiratory infections followed by the development of complications requiring continuous treatment with antibiotics.After reaching mean age of 15 years old, the intensity of infection-associated antibody deficiency was 6-8 times per year. After verification of the diagnosis, the patients received replacement therapy, first at the saturation dose, and, after stabilization of IgG at the level of 7-8 g/l, at the monthly maintenance dose. The clinical course of the disease was traced during a full year of replacement therapy, and the cellular immunity indices were evaluated. In all patients, after a year of therapy corresponding to clinical guidelines, there was an improvement in quality of life indices, decreased rates of recurrent bacterial infections. At the same time, 40% of them continued to suffer, on average, 5.4±1.1 times a year and required long-term courses of antibiotic therapy. Evaluation of immune status did not reveal statistically significant differences in IgG plasma saturation between the groups of patients with different treatment efficiency: 8.7 (8-9) g/l and 9.1 (8.5-10.5) g/l, at p = 0.5. The differences related to immune cell factors in cases of smaller effect of IVIG therapy are manifested in higher relative numbers of T effectors containing lytic Granzyme B granules and CD14+CD284+ monocytes, accompanied by lower spontaneous active oxygen forms produced by neutrophils, lesser contents of CD16+ natural killers in peripheral blood.The obtained data illustrate the value of monitoring, not only serum IgG level, but also the parameters of the cellular immune response. Such analysis may be essential as a prognostic criterion for efficacy of IVIG therapy. Reduced levels of some parameters of innate immunity cells serves a basis to formulate the concept of combined treatment and usage of tools that alter functions of immunocompetent cells.

Lactobacilli are widely used in clinical practice as probiotics, biologically active additives and probiotic products for functional nutrition. Some probiotics can be considered as bacterial vaccines due to induction of immune response, accompanied by production of specific antibodies. The aim of the present study was to evaluate the state of cellular and humoral immunity in women by using probiotic strains of lactobacilli. The study included 31 healthy women aged 25-45 years. As a source of probiotic lactobacterial complex, we used the “Provag” preparation (RU 77.99.11.003.E.003746.02.11 of 11.02.2011, 1 capsule contains 109 Lactobacillus gasseri 57C, Lactobacillus fermentum 57A и Lactobacillus plantarum 57B). The drug was used for 30 days, at a rate of one capsule per day. The immune system was examined twice: before administering the drug and after 30 days of treatment. The study of blood lymphocyte populations and subpopulations was performed by flow cytometry using direct immunofluorescence technique. The concentration of IgA, IgM, IgG in blood serum was determined using enzyme immunoassay. To determine specific antibodies, we used passive hemagglutination reaction with erythrocyte diagnosticum. The complex of probiotic lactobacilli Lactobacillus gasseri, Lactobacillus fermentum and Lactobacillus plantarum corresponding to the “Provag” preparation was used as a source of antigen. It has been revealed that the number of T and B lymphocytes in peripheral blood increased after 30 days of treatment with the probiotic preparation “Provag” in healthy women. Elevated contents of T cells was due to the T helper cell fraction. Increased levels of T helpers and B lymphocytes were associated with stimulation of humoral immunity, as evidenced by increasing concentration of IgA and IgG in blood serum. By means of passive hemagglutination reaction, we have found that 90% of healthy women showed increased concentrations of specific IgA in blood after 30 days of treatment with “Provag” preparation.

Published: August 2020

Current study performed to estimate the phagocytic activity of blood monocytes of varying phenotypes exposed to MRSA and MSSA strains. Objects: Blood monocytes were collected from 25 healthy adults (age: 25–45 years). Live suspensions of MRSA/MSSA strains were used at concentration of 106 colony-forming units (CFU)/mL. Metods. Phagocytic functions were estimated by using fluorescein isothiocyanate (FITC)-labelled MRSA and MSSA strains followed by running flow cytometry on FC 500 series flow cytometer (Beckman Coulter, USA). Whole peripheral blood cells were directly labelled with immunofluorescently tagged monoclonal CD14-PE/CD45-ECD/HLA-DR-PC5/CD16-PC7 antibodies (Beckman Coulter, USA). Respiratory burst intensity was evaluated in monocytes by measuring activity of lucigeninand luminol-dependent spontaneous and induced chemiluminescence. Monocytes were induced by using live suspension of MRSA/MSSA strains at a concentration of 106 CFU/mL. Results and discussion. While studying luminol-dependent monocyte activities after exposure to MRSA vs. MSSA, it was observed a 3.5-fold decreased curve square, whereas lucigenin-dependent chemiluminescence was increased by 6-fold. Compared to MSSA exposure, index of activation (IA) was decreased by 1.1-fold in response to MRSA exposure that was confirmed by lowered release of reactive oxygen species (ROS) from monocytes in response to MRSA exposure. Moreover, IRSS increased by 1.3-fold upon MRSA exposure. Examining monocyte oxygen-independent phagocytosis against MRSA vs. MSSA revealed significantly increased phagocytic number and concomitantly decreased phagocytic index. An evaluation of the activities of various monocyte subsets in response to MRSA vs. MSSA revealed increased phagocytic index by 1.5-fold for CD14lowCD16+ and CD14+CD16+ monocyte subsets as well as 3-fold for CD14+CD16– monocytes. Counts for all phagocytic subsets were decreased (1.4-, 1.5- and 4-fold for CD14lowCD16+, CD14+CD16+ and CD14+CD16– monocytes, respectively). To summarize, intensity of the respiratory burst was lowered upon MRSA exposure and percentage of monocyte subsets. Overall deficiency of superoxide anion production was observed in response to MRSA. In contrast, oxygen-independent event revealed phenotypic changes in frequency of peripheral blood monocytes upon MRSA exposure. We observed that CD14+CD16– classical monocytes were more rapidly activated. Conclusion. Thus, we concluded that CD14+CD16– monocytes became more rapidly activated but exhibited less effective phagocytosis, whereas CD14+CD16+ and CD14lowCD16+ monocytes were more slowly activated and demonstrated stronger phagocytic activity.
