Differences between determinants of men and women monthly wages across fourteen European Union states
Authors: Matuszewska-Janica Aleksandra , Witkowska Dorota
Published: October 2021

Research background: There is a broad discussion in the literature on the situation of men and women in the labour market, especially about the differences in their remuneration. Due to the fact that females constitute a slightly different group of employees, certain factors have different impacts on the level of their remuneration in comparison to male employees. Hence, the question arises which factors cause these differences and how large the dissimilarities are.

Purpose of the article: The aim of the presented study is to diagnose and evaluate differences in the impact of designated determinants on the level of monthly wages of women and men in selected European Union member states. The novelty of our approach consists in both comparison of the intensity of influence examined factors to men?s and women?s earnings, and a global approach to the remuneration of male and female employees.

Methods: Due to the nature of the dependent variable (remuneration decile, which is a variable measured on an ordinal scale), the ordered logit model is applied in the analysis. The data comes from the Eurostat?s Labour Force Survey.

Findings & value added: Presented results indicate that many factors have significantly different intensity of impact on the level of men and women wages. However, significant differences between parameters estimated for both genders are visible for the group of family variables the most often, then for variables describing the condition of work, the human capital variables, and characteristics of the workplace. This paper adds to the empirical literature a new approach to measure the intensity of factors influencing men and women wages. In addition, our investigation is a cross-country analysis.

The COVID-19 pandemic has affected various sectors of the global communities, including those that depend on forests for honey products. Furthermore, the dynamics of production and availability are completely affected by government restrictions. This study focuses on the short-term effects of the COVID-19 pandemic on the forestry sector. Specifically, it examines the pandemic effect on forest honey farmers in habitat management, harvesting, marketing, farmer institutions, and livelihoods. The study was conducted on forest honey bee farmers through field observations and structured and in-depth interviews. Data were collected using five variables and 30 indicators in Fatumnasi Subdistrict, South Central Timor Regency and analyzed using descriptive and quantitative analysis. The results showed that the COVID-19 pandemic has changed the socio-cultural and economic utilization of forest honey. Additionally, social restrictions have reduced habitat management performance, farmers institutions and livelihoods, harvesting, and marketing. This has increased pressure on the livelihoods of forest honey bee farmers than before the pandemic. Moreover, it has directly affected their lives and the ability to provide quality forest honey. Therefore, interventions are needed to strengthen marketing and institutional networks to face the changes during and after the COVID-19 pandemic.

ABSTRACT

Tuberculosis (TB) is one of the public health problems that cannot be overcome. The problem is caused by several factors, one of which is the non-compliance of patients with treatment. In Indonesia, the incidence of TB cases is 842,000 per year and notification of TB cases is 569,899 cases, so there are still around 32% of the cases that have not been verified either unreached, undetected or not reported. From this incident rate the TB burden is calculated in each province and district / city, (Indonesia, 2019). Purpose: Identify factors related to adherence to the treatment of pulmonary TB patients in the working area of ​​Garuda Bandung Puskesmas. Method: This is an analytic case study with a case control design. The sample of this study was 43 pulmonary TB patients taken in total who failed and were removed from treatment in 2017. The research instrument used a questionnaire. Data analysis using chi square. Results: The most dominant factors affecting adherence to treatment among pulmonary TB patients were Gender P value (0.014) and occupational Pvalue (0.025) where p <0.05 while factors not related to medication adherence were age, knowledge, education, and family income, p> 0.05. Conclusion: Gender and occupation have a significant relationship to tuberculosis treatment adherence, while age, knowledge and family income have no significant relationship to tuberculosis patient adherence.

Authors: da Silva Rodrigo Romano , Pereira Graziane Olímpio , Macari Soraia , Barbosa Jurandir Antonio , Basting Roberta Tarkany
Published: October 2021

Objectives:

This study aimed to evaluate the frictional resistance produced by active and passive self-ligating brackets on stainless steel archwires in the absence or presence of elastomeric chains under or over the wire.

Materials and Methods:

Four types of self-ligating brackets were used: Two active and two passive. For each commercial brand, five brackets were bonded to an acrylic plate and the frictional resistance was evaluated with 0.018” and 0.019” × 0.025” stainless steel wires in three situations: Without elastomeric chain, with elastomeric chain placed under and over the wire.

Results:

The bracket type, cross-section of the wire, and type of ligation had significant interactions with each other; the frictional resistance was significantly lower with the use of passive self-ligated brackets, while no difference was found when a 0.018” wire was tested. Moreover, the frictional resistance in the absence of an elastomeric chain, or when the chain was under the wire, was significantly lower in comparison with the values obtained when the chain was placed on the wire.

Conclusion:

Frictional resistance of passive and active self-ligated brackets is influenced by the ligation methods and the cross-sectioning of archwires.

Authors: Da Jason Chua Sheng , Seneviratne Chaminda Jayampath , Wong Hung Chew , Yow Mimi
Published: October 2021

Objectives:

The objectives of the study were to investigate the in vitro and in vivo effects of various removable orthodontic retainer materials on clinical and microbiological parameters, specifically on saliva characteristics, oral hygiene, and salivary levels of Streptococcus mutans (S. mutans).

Materials and Methods:

This study consists of two parts: An in vitro study and in vivo prospective clinical pilot study. The in vitro study measures surface roughness and S. mutans adhesion of three orthodontic retainer materials: Polymethylmethacrylate (PMMA) used in traditional Hawley removable retainers, polypropylene (PP), and polyurethane (PU) used in vacuum-formed retainers. In the clinical pilot study, 20 subjects, on completion of orthodontic treatment were randomized into three groups to receive PMMA, PP, or PU removable orthodontic retainers. They were compared with control subjects with no orthodontic treatment and retainers. Quantitative analysis of salivary S. mutans using real-time polymerase chain reaction was performed to screen for differences during retainer issue (T0) and 8–15 weeks later (T1). Salivary flow rate, pH, buffering capacity, and plaque scores were also recorded at these two periods for comparison.

Results:

PMMA had significantly greater surface roughness and S. mutans adhesion than PP and PU (P = 0.027). The PMMA group displayed significantly greater amounts of salivary S. mutans count when compared to the PP (0.001) and PU (P = 0.011) groups.

Conclusion:

PMMA retainers showed increased S. mutans adhesion and intra-oral colonization of S. mutans compared to PP and PU retainers. The results validate further clinical testing for a relationship between caries risk and type of retainer prescribed.

Published: October 2021

Objectives:

The aim of this paper is to present a diagnostic algorithm for a controversial topic in ophthalmic oncology, small pigmented choroidal tumors (<3 mm thick).

Material and Methods:

Nineteen consecutive patients with a clinical diagnosis of small choroidal pigmented tumors were included in the study. The group of patients studied consisted of 9 patients (47.36%) female and 10 patients (52.64%) male, the age range was 14–68 years. All cases were ophthalmologically evaluated, including best-corrected visual acuity, anterior and posterior segment biomicroscopy, intraocular pressure, binocular indirect ophthalmoscopy, and as additional complementary examinations, ocular ultrasound was performed, which in 100% of the cases was inconclusive, optical coherence tomography, autofluorescence, and angiography in selected cases according to location and symptomatology. In 13 patients (68.50%), transvitreous puncture was performed with or without vitrectomy. Trans-scleral puncture was performed in 6 patients (31.50%), located at the equator (4 patients) and ciliary body (2 patients). Post-surgical follow-up was performed within the first 3 weeks after the procedure and then controlled every 3 months within the 1st year. The material obtained by fine-needle aspiration (FNA) was placed in non-hemolytic preservative liquid. Hematoxylin and eosin, Pas, Masson’s trichrome, and immunohistochemistry (HMB 45, MELAN A, PROT. S-100 base) were performed.

Results:

The yield of cytologic material was 100% in the sampled patients. The most frequent complication was subretinal hemorrhage in three patients with transvitreous access and two patients with trans-scleral access, in all cases, there was a favorable evolution without requiring further action. In three patients, there were mild vitreous hemorrhages that resolved spontaneously, all of them had undergone transvitreous access.

Conclusion:

In TPPC of less, we propose a diagnostic algorithm with FNA to obtain cytological sample which allows not only the diagnosis of certainty to indicate treatment but also to determine cytological and molecular prognostic factors that allow classifying melanoma of high or low grade and potentially in case of metastatic disease to indicate systemic treatments. We believe that it is essential to diagnose this type of lesions in which a diagnosis of certainty is required. The alternative is the observation that we consider potentially dangerous in these cases.

In den Lehrplänen einiger Bundesländer gibt es noch keinen eigenständigen Themenbereich Teilchenphysik. Für diesen Fall sind die hier vorgestellten Mikrokurse zusammengestellt worden. Alle Kurse schlagen auf originelle Weise eine Brücke von klassischen Lehrplanthemen zu aktuellen Forschungsgegenständen. Denn viele der im Physikunterricht behandelten Themen lassen sich leicht um einen Bezug zur modernen Physik und insbesondere der Teilchenphysik ergänzen. Der zeitliche Bedarf für die Behandlung eines Kurses beträgt ca. ein bis zwei Unterrichtsstunden. Vorkenntnisse zur Teilchenphysik sind kaum notwendig. Die Mikrokurse können und sollen deshalb auch gerade dort eingesetzt werden, wo nur wenig Zeit zur Verfügung steht oder das Thema Teilchenphysik nicht im Lehrplan verankert ist. Zu jedem Kurs werden Einsatzmöglichkeiten und wünschenswerte Vorkenntnisse der Schüler:innen angegeben. Auf mögliche Erweiterungen und Vertiefungen wird hingewiesen.
Solving the Dirichlet problem for the Poisson equation by the least squares collocation method with given discrete boundary domain
Authors: Беляев В.А. , Шапеев В.П.
Published: October 2021

Предложен и реализован новый вариант метода коллокации и наименьших квадратов повышенной точности для численного решения уравнения Пуассона.
Реализованный алгоритм применяется в неканонических областях, границы которых заданы дискретно. Для приближенного и однозначного задания границы
области по ее дискретным данным в прямоугольной системе координат строится параметрический двойной сплайн, в качестве компонент которого взяты два кубических сплайна. Используется идея присоединения вытянутых несамостоятельных нерегулярных граничных ячеек к соседним самостоятельным с целью уменьшения
обусловленности глобальной системы линейных алгебраических уравнений.

The paper addresses a new version of the least squares collocation (LSC) method proposed and implemented for the numerical solution of boundary value problems for the Poisson’s equation in case of given discrete domain boundary. The computer program builds a continuous double spline when boundary is smooth or a piecewise smooth double spline if boundary has salient points. In this version of the method we apply the idea of using parts of the cells of a regular grid (outside the domain). These parts of the cells are cut off by the boundary to construct the LSC method. It is
assumed that the solution has no singularities at the boundary and in a certain small neighborhood of it. The differential equation for the problem is correct not only in the computational domain but also in a small neighborhood of its boundary. Then the idea of attaching “small” irregular cells to neighboring ones is used in the work with the aim of reducing the number of conditionality of the global system of linear algebraic equations. It is shown that the approximate solutions obtained by the LSC method converge with an increased order and coincide with the analytical solutions of the test problems with high accuracy.

There are various approaches to the algorithmic specification of the network structure in the deep learning problems, which are successfully used in applications. These methods can be generalized by the concept of procedural generation of neural network architectures. Methodology. In the work, we use binary matrix filters. The filters are obtained with the help of the Hadamard product. Such filters define active network modules, thereby changing the way information is transmitted between layers. To build various architectures, the theory of braids is used in the work. The article reproduces the wellknown PathNet architecture. Examples of generating three new deep neural network architectures (3DNN, GraphNet, and BraidNet) are examined. Findings. The paper shows how the procedural generation of neural network architectures allows avoiding manually setting the network structure and automatically forming it. The use of matrix filters simplifies the process of generating network architecture due to a large number of possible combinations of modules and connections between them. Using the MNIST classification problem as an example, it is shown how the architectures presented in the article solve real-world pattern recognition problems. The results of application of neural networks indicate their diminishing tendency to retraining due to the subsequent convergence and the presence of stochastic dynamics in the learning process. Originality/value. Learning methods with dynamic adaptive changes in the network architecture allows achieving satisfactory accuracy faster and should also be less prone to retraining. The BraidNet algorithm presented in the article is applicable for ICT SB RAS, 2019 a convenient brief record of the structure of a neural network in genetic algorithms. Such features make BraidNet a promising algorithm for further application and research in complex problems of pattern recognition, including using neuroevolutionary approaches.

Представлена модель вскипающей жидкости, построенная на базе ранее предложенной автором обобщенно-равновесной модели смеси. В модели учтена сжимаемость жидкой фракции. Проведен характеристический анализ уравнений модели и показана их гиперболичность. Приведены расчетные формулы узлового метода характеристик, с использованием которого рассчитано течение при распаде произвольного разрыва во вскипающей жидкости.

A model of a boiling liquid is presented, built on the basis of a one-speed two-temperature mixture model previously proposed by the author, in which the forces of interfractional interaction are taken into account. The liquid fraction was considered compressible. A characteristic analysis of the equations of the model is carried out and their hyperbolicity is shown. Relations for characteristic directions and differential relations along these lines are written. An analytical formula for calculating the speed of sound in a boiling liquid is obtained. It is noted that the speed of sound in a liquid when taking into account phase transformations is somewhat lower than is predicted by the Wood formula. The calculation formulas of the iterative algorithm of the nodal method of characteristics are presented, which implies that the flow is calculated during the decay of an arbitrary rupture in a boiling liquid. In the calculations, it was assumed that the phase transition during the boiling process occurs under conditions of an overheated state, when the temperature of the liquid exceeds the saturation temperature. It is shown that taking phase transformation into account leads to a significant increase in the vapor concentration in the unloading wave, as well as to a small increase in both the speed of the mixture and pressure. The concentration of the vapor fraction behind the shock front decreases.

Работа посвящена построению и апробации микромасштабной математической модели и численного метода ее решения для исследования турбулентных течений и переноса пассивной газообразной примеси в уличных каньонах. Представлены результаты исследования структуры течения в уличном каньоне в зависимости от соотношения ширины улицы и высоты зданий, а также результаты расчета неизотермического турбулентного течения в условиях влияния естественной конвекции.

The study is focused on developing and testing a microscale mathematical model for the analysis of turbulent flow and passive gaseous admixture transfer in street canyons. Mathematical model is based on Reynolds-averaged NavierStokes and continuity equations. Boussinesq approximation and two-parameter k-epsilon turbulence model is used to close the equations. Numerical solution of the system of differential equations is obtained with the finite volume method on a staggered mesh. Convective terms of the NavierStokes equations are approximated with MLU numerical scheme. SIMPLE computational algorithm is used to couple velocity and pressure fields. Laminar flow on the inlet section of the 2D channel was modelled to test the computational algorithm. Turbulent flow and emission transport in a wind tunnel was modelled to verify the mathematical model. Series of computations of the flow influenced by natural convection in an ideal model of street canyon were performed using the presented mathematical model. Computations were performed for a 24 m height and 20 m wide street canyon. The constant emission source was placed in the center of the canyon near the floor. Analysis of the results has showed that in cases of heating the upwind side or the bottom of the canyon emissions are transported out of the canyon more intensively and maximal concentrations decrease by 1015 from the isothermal case. In case of heating the downwind side the structure of the flow changes significantly and maximal concentrations increase by 33.5 times. The structure of the flow in the street canyon was investigated depending on the ratio of the street width to the height of the buildings. Both width of the street and height of the building varied from 5 to 40 m. The results show that increase in the height of the canyon decrease ventilation of the street canyon and increases local maximal concentrations of adverse emissions.
Aufwachsen in stationärer Jugendhilfe und die Bedeutung für den biografischen Verlauf betroffener junger Menschen – eine empirische Längsschnittanalyse zum Sozialisationskontext Heimerziehung

Published: October 2021

Die selbst- oder fremdbestimmte Unterbringung von Kindern und Jugendlichen in einer Maßnahme der stationären Erziehungshilfe stellt einen starken Eingriff in deren biografischen Verlauf dar. Über die langfristigen (sozialisatorischen) Auswirkungen des Aufwachsens in Einrichtungen der Heimerziehung sind nur wenige Erkenntnisse vorhanden.

In diesem Artikel gehen wir anhand einer Einzelfallanalyse der Frage nach, welche Sozialisationseffekte aus dem Lebensereignis Heimerziehung emergieren und wie sie im weiteren biografischen Verlauf von Adressat*innen sichtbar werden. Das längsschnittliche Datenmaterial basiert auf fünf Interviewerhebungen über einen Gesamtzeitraum von zehn Jahren während und nach dem Aufenthalt in Einrichtungen der stationären Jugendhilfe. Wir identifizieren und analysieren emergierende Sozialisationseffekte in ihrer Bedeutung für den weiteren biografischen Verlauf entlang der drei Analysedimensionen Wohnen, soziale Beziehungen und beruflicher Werdegang. Dabei wird die Bedeutung eines verlässlichen Beziehungsangebots pädagogischer Fachkräfte sowie eines auf die individuellen Bedürfnisse von fremduntergebrachten jungen Menschen abgestimmten professionellen Handelns sichtbar.

Three series of experiments were carried out and lethal doses of the new osteoplastic material 47.5 V were determined by the intraperitoneal and intragastric injection of the material to laboratory animals. A comparative evaluation with Bioactive glass BG-1D was also carried out. It was found that the LD50of 47,5B was 4274.51:4770.58 mg/kg for intragastric injection and 2358.31:2895.65 mg/kg for intraperitoneal injection to rats. In animals getting Bioactive glass BG-1D, these indicators changed slightly, amounting to 3439.04:3810.53 mg/kg and 1732.77:2730.93 mg/kg, respectively. Thus, according to the classification of substances according to the degree of toxicity, these materials can be attributed to practically non-toxic substances (according to the results of intraperitoneal injection of the material suspension to rats and mice) and low-toxic substances (according to the results of intragastric injection of the material suspension to rats)

The immunograms of 93 sick children with chronic purulent otitis media on the background of chronic hepatitis (39 mesotympanitis and 54 epitympanitis) were studied. A comparative analysis of immunogram indices was carried out depending on the severity of inflammatory changes and the inclusion of imunofan in the therapy regimen. The results of the work showed that in sick children with chronic purulent otitis media against the background of chronic hepatitis, the immunogram reflects the peculiarities of the course of the inflammatory process. Chronic inflammatory process in the temporal bone and surgical trauma sharply suppress cellular and humoral immunity, which prompts the use of immunocorrectors in the scheme of postoperative treatment. The inclusion of imunofan in the therapy scheme allowed to completely normalize the immunogram indices in patients with epitympanitis and to improve the clinical course of the postoperative period
