Comprehensive Traffic Calming as a Key Element of Sustainable Urban Mobility Plans—Impacts of a Neighbourhood Redesign in Ljutomer
Authors: Balant Mojca , Lep Marjan
Published: October 2020

Negative impacts of motor vehicle traffic in cities are still increasing despite the objectives that sustainable mobility paradigm put forward almost three decades ago. Measures to reduce them still primarily focus on traffic safety improvements through vehicle speeds and flows reduction (traffic calming). Comprehensive traffic calming, a measure of sustainable urban mobility planning, targets the issue more comprehensively by also addressing changes in travel behaviour and quality of life. Literature covering the effects of measures addressing all listed aspects is scarce. In this paper, we present results of a longitudinal study of a comprehensive traffic calming redesign of a residential neighbourhood in Ljutomer in Slovenia. The following set of indicators was monitored: travel habits of neighbourhood residents, quality of living environment, acceptability of redesign, vehicle flows, speeds and classes, and traffic accidents. Motorized traffic counts, pilot interviews, postal and in-person surveys and public databases on traffic accidents were used to gather data before and after the redesign. All monitored indicators showed positive results. Around a third of residents claim to walk, cycle and socialize more than before the redesign while around two thirds state that the quality of life in the neighbourhood has improved. Vehicle speeds, flows and peak hour flows have notably decreased, and road safety has improved. The results show that the comprehensive traffic calming approach has a broad range of positive effects and contributes to achieving sustainable mobility. Its potential for a wider use in sustainable urban mobility planning practice is substantial.

Authors: Islam Maidul , Kim Dan-A. , Kwon Minjoo
Published: October 2020

This paper employs a comparison between two forms of online instruction to investigate which form is more preferred, as well as the advantages and the disadvantages for both forms of online education. The data for the research were collected via an online questionnaire that was purposely created for the research. A sample of 26 undergraduate students of Yonsei University, South Korea, were employed for this study. Pre-tests and post-tests were performed to compare between pre-recorded video lectures and live ZOOM lectures. The results show that students prefer pre-recorded video lectures to live ZOOM lectures; 53.8% chose pre-recorded video lectures, 7.7% chose live ZOOM lectures, and 30.8% chose both pre-recorded and ZOOM lectures when they were asked to select their preferred method of learning. Furthermore, we asked several questions, and the mean values were compared. The results of this research showed that pre-recorded video lectures are preferred to live ZOOM lectures due to their flexibility, convenience, and educational effectiveness. However, learning through video lectures depends on students’ motivation to get through those materials on their own. Lack of motivation and clear deadlines to watch those video lecture materials could end up in an accumulation of workload, which would be difficult to overcome before examinations.
Symmetric and Asymmetric Components of Shape Variation in the Diatom Genus Frustulia (Bacillariophyta)
Authors: Kulichová Jana , Urbánková Pavla
Published: October 2020

Irregularities in cell division can produce asymmetry in symmetric structures, such as outlines of diatom cells, which can reflect genetic, environmental, or random variability in developmental processes. This study examined 12 phylogenetic lineages of the diatom genus Frustulia using landmark-based geometric morphometrics to assess the variation between cell segments separated by apical and transapical axes. Although asymmetric variation within cells differed in some lineages, these irregularities most likely did not reflect the evolutionary history of the lineages. The intraclonal phenotypic plasticity of diatom frustules was induced rather by nongenetic factors, i.e., inherited valve abnormalities, constraints of siliceous cell walls, and random developmental instability during morphogenesis. The positive correlations between the symmetric and asymmetric components of shape variation indicated that the morphogenesis of diatom cell walls affected irregularities within cells and variability among the symmetrized cells to a similar extent.
Three-Dimensional Unstructured Grid Finite-Volume Model for Coastal and Estuarine Circulation and Its Application
Authors: Lee Jun , Lee Jungwoo , Yun Sang-Leen , Kim Seog-Ku
Published: October 2020

We developed a three-dimensional unstructured grid coastal and estuarine circulation model, named the General Ocean Model (GOM). Combining the finite volume and finite difference methods, GOM achieved both the exact conservation and computational efficiency. The propagation term was implemented by a semi-implicit numerical scheme, the so-called θ scheme, and the time-explicit Eulerian–Lagrangian method was used to discretize the nonlinear advection term to remove the major limitation of the time step, which appears when solving shallow water equations, by the Courant–Friedrichs–Lewy stability condition. Because the GOM uses orthogonal unstructured computational grids, allowing both triangular and quadrilateral grids, considerable flexibility to resolve complex coastal boundaries is allowed without any transformation of governing equations. The GOM was successfully verified with five analytical solutions, and it was also validated when applied to the Texas coast, showing an overall skill value of 0.951. The verification results showed that the algorithm used in GOM was correctly coded, and it is efficient and robust.

Authors: Nosonov Arthur
Published: October 2020

The article considers the possibilities of using geoinformation technologies in studying vertically integrated structures in agriculture of Russia as an important factor of innovative development of the agrarian sphere at the present stage. The use of GIS technologies is an effective tool for identifying spatial patterns of placement of the largest vertically integrated formations (agroholding) and the level of their territorial concentration by regions of Russia. Geo-information technologies are also an effective method of exploring the territorial and functional structure of large agroholdings at the regional (meso-) level. The strategic importance of large vertically integrated structures in ensuring the food security of the country was analysed. The important role of agroholdings is noted in ensuring innovative modernization of agriculture and in ensuring commercialization of innovation as a result of improvement of the material and technical base of agro-industrial complex and application of new technologies: efficient soil processing technologies, information technology of production process management, agricultural robotics and wider use of GIS-technologies for agro-management and support of agrotechnical operations. In order to identify and investigate spatial and temporal regularity of territorial organization of agroholdings, possible options were identified and thematic databases for GIS ArcView GIS were developed, which are the basis for geographic information modeling and mapping of various aspects of placement of vertically integrated structures. Functional and organizational-management structure of agroholdings is considered. Factors of formation and territorial differentiation of agroholdings in different regions of Russia have been identified and analyzed, the largest land users have been identified and the rating of the largest vertically integrated structures by revenue has been given. Spatial analysis of patterns of formation and development of agroholdings was carried out, positive and negative consequences of their functioning were revealed. The territorial and sectoral structure of a large regional agroholding in the Republic of Mordovia was studied in detail, the main factors of the functioning and development of this form of organizational and managerial innovations were identified.

The study is devoted to the research of the dependence of the processing results of photoresistive films on the silicon wafers surface in an ozone environment on the conditions and parameters of the process. The high oxidizing potential of ozone justifies the possibility of its use for removing organic films under atmospheric pressure. The experiments were carried out using the developed research bench, in which the mode and method of heating, as well as the method of supplying gas to the surface of the photoresist, were varied. Silicon wafers with a formed 1,35-μm thick masking photoresist film were used as experimental samples. It was found expedient that uniform heating of the plate over its entire surface can be achieved using a ceramic IR heater. When the ozone-air mixture was introduced into the center of the heated sample, the presence of the removed photoresist residues was observed, which was associated with a temperature drop in its surface area. To solve this problem, the computer models of the temperature regimes of the reaction volume elements were calculated. They showed that the scattering of the working gas flow over the surface of the silicon wafer would significantly increase the efficiency of photoresist removal, and with a good selection of the treatment regime it would ensure complete removal of the photoresist. The data obtained were experimentally confirmed by using an ozone-air mixture flow separator. Experiments were carried out to study the effect of the distance from the wafer surface to the working gas inlet on the photoresist removal rate. They showed that a decrease in the distance reduces the ozone loss due to thermal decomposition and, consequently, increases the material removal rate.

Published: October 2020

During the pregnancy period woman repeatedly seeks medical aid and consults different medical specialists. Meanwhile, there is no continuity for dynamic monitoring of pregnant woman’s health. The level of knowledge of medical personnel concerning prevention of main dental diseases must be high enough, as the influence on manageable risk factors is under their responsibilities. However, this level is confirmed neither in Russian, nor in the foreign literature. Aim - study of awareness of medical personnel who monitor pregnant women on the issues concerning prevention of dental caries and periodontal diseases. Data and methods. A survey was conducted among 127 medical doctors of different specialities (obstetrician-gynecologists, dentists, pediatricians), working for state budgetary public health organizations of Samara. Results. The study highlighted a low level of primary health care doctors’ awareness on preventive measures for the main dental diseases of pregnant women (absence of motivation for dental diseases prevention and oral hygiene, inadequate knowledge about fluoride importance for caries prevention, exaggeration of the influence of non-manageable risk factors (heredity, ecological environment) on dental pathology development, a high level of reliance on information from the mass media about preventive measures in dentistry). Conclusion. It is necessary to improve the level of knowledge of doctors who monitor pregnant women. It can be achieved by the increase of doctors’ awareness (organization of lectures and seminars, development and production of visual aids for doctors of different specialities and mid-level medical staff).

Aim - the determination of microscopic diagnostic features of rhizomes of common turmeric (Curcuma longa L.), ginger family (Zingiberaceae). Materials and methods. We have studied whole, milled and powdered plant material of turmeric from different manufactures. The study was carried out with the use of the digital microscopes “Motic DM111” (Korea) and “Motic DM-39C-N9GO-A” (Korea). Results. It was determined that the microscopic diagnostic features of rhizomes of turmeric include the presence of cells with sinuous walls and structured content in the form of colored folding in the parenchyma; closed collateral vascular bundles lie scattered in the parenchyma, their conductive elements have narrow lumen. Vascular bundles contain pigment cells considerably smaller in comparison with the size of vessels. Pigment cells with drops of orange-red essential oil are also found in the parenchyma. In milled and powdered plant material, the fragments of all these elements are observed. In the fragments of powdered rhizomes of turmeric, numerous cells with yellow content are found; the parenchyma cells have less expressed folded structure. Fragments of vessels are found both in milled and powdered material. Conclusion. The results of this study were included in the section “Microscopy” of the project of pharmacopoeial monograph “Curcuma longa L. rhizomes”.

Published: October 2020

The study presents technology of the development of formalized forecasting model of the risk group for temporomandibular pain dysfunction syndrome on the basis of a systemic analysis of multivariate rapid screening questionnaire for prevalence rate of etiological and amnesic predisposing factors and manifestations of TMJ pain dysfunction syndrome. Formalized model allows us to identify an individual consulting and diagnostic itinerary of the subject, to diagnose the cause of abnormalities in the biomechanical system, to conduct timely correction, and to start the treatment. Aim - development of affordable formal risk prediction method for predicting the development of TMJ pain dysfunction syndrome. Materials and methods. The subjects of the study were 94 respondents, 34 men and 60 women aged from 18 to 57 years, chosen by accidental sampling. The following methods were used: sociological (rapid screening questionnaire), systemic multivariate analysis, regression analysis, mathematical modeling. The study was conducted with consistent integration of rapid screening questionnaire data of clinically healthy research subjects and those with signs of TMJ dysfunction, who did not complain and did not seek dental advice concerning the changes in the TMJ. Integration was carried out by multivariate systemic analysis of personal data and the assessment of changes in the dentition of all the subjects of the sampling. The two components were taken into account in the survey system corresponding to the two data blocks: "causes" and "effects". Information from the subjects of study was obtained by the principle of dichotomous presentation, during which the test subjects noticed the presence or absence of a specific sign (symptom) in the dentition. Results. Boundary values of the integral system status indicator (min Xbi = 0,04 + 0,01, max 0,11 + 0,04) were calculated, whereby the test subject can be attributed to the risk group for the causes and predisposing factors or the first manifestation of symptoms of TMJ pain dysfunction syndrome. Conclusion. The subjects of the research with the values of the integral index falling within the confidence interval boundary values of the modified system (from Xbi = 0,04 ± 0,01 to Xbi = 0,11 ± 0,04) require determination of an individual trajectory of system correction.

Aim - to evaluate the effectiveness of surgical correction of shortening and axial deformities of the lower extremities in children by temporary blocking of the growth zones. Materials and methods. The article presents five-year experience (2011-2016) in the treatment of 45 children (59 knees) with deformities of the lower extremities of different etiology. These cases included such congenital and acquired deformities as post-traumatic deformities, Blount's disease, metaphyseal dysplasia, after-effects of osteomyelitis, exostotic chondrodysplasia. Shortening or elongation of the limbs were found in 13 patients, the angular deformity - in 29 patients, combined deformity - in 3 patients. Results. In our practice, the timing of the correction of deformity ranged from 10 to 32 months. The degree and time of correction of the deformation directly depend on its severity and age of patients. The analysis of the results of the treatment of children with the use of this methodology showed the following results: good outcomes were observed in 37 patients (82.2%), satisfactory - in 8 patients (17.8%), unsatisfactory outcomes were not observed. Complications occurred in 3 patients (6.6%). Irreversible complications were not observed. Conclusions. Method of temporary blocking of the growth zones of long bones (method of controlled growth, temporary epiphysiodesis) is a good alternative to corrective osteotomies due to sufficient efficacy, minimal invasiveness, and little risk of complications.

In our opinion, for correct diagnosis and provision of qualified care to sick children it is necessary to raise awareness of parents and primary care physicians about the dangers of this pathology. If there is a reason to suspect a foreign body in the airways, consultation in a specialized institution is vitally important. The only correct method of treating children with foreign body in the airways, even at the slightest suspicion, is timely performed tracheobronchoscopy.

Aim - to study the peculiarities of metabolic and functional activity of cell factors of congenital immunity in patients after rhinosurgical treatment in early stages of post-operative period. Materials and methods. The authors examined leukocyte profile of nasal secretion and their viability, phagocytic and lysosomal activity, oxygen-dependent biotransformation of neutrophilic granulocytes in NBT-test during the first 24 hours after the operation for deflection of the nasal septum. Results. The study showed that spontaneous NBT-test during the first 24 hours of postoperative period revealed that patients after the operation for deflection of the nasal septum with the following 24-hour tamponade have increased number of viable neutrophilic granulocytes with better lysosomal activity, decreased phagocytosis activity and intensity, and depressed biocidal characteristics. Conclusion. The revealed increase in the number of viable neutrophilic granulocytes, their better lysosomal activity, associated with decreased phagocytosis activity and intensity, and depressed biocidal characteristics prove the need for the search of additional methods of postoperative rehabilitation.

Aim - to prove the necessity of including the methods, which normalize the vascular and intravascular component of the hemostasis system, in the combined therapy of inflammatory periodontal diseases, as the microcirculation disorders play the most important role in the pathogenesis of inflammatory periodontal diseases and correlates with severity level. Materials and methods. In order to study the possibility to correct the malformation of the adhesive and aggregation activity of the blood platelets in patients with inflammatory periodontal diseases, we carried out a study of the adhesion and aggregation of platelets after a course of combined therapy, which included combined effects of laser and EHF radiation. The most important link in restoration of microcirculation is the vasoregulative effect of laser irradiation. Results. There is a partial or complete restoration of aggregation and adhesive activity of the blood platelets. Conclusion. The use of combined laser and EHF radiation of the “Matrix” equipment allows stopping the inflammation of the tissues quickly. Correction of these disorders by non-drug methods, in comparison with a medication-assisted treatment, has no side effects, and can be recommended as a component of combined therapy in patients with inflammatory periodontal diseases.

Aim - to study the informativeness of the analysis of oral fluid parameters to assess the state of metabolism in patients with obesity. Materials and methods. The article studied the indicators of oral fluid and blood, wich characterized the metabolism, among 58 patients with II type of obesity (36 women and 22 men, mean age 39.5±6.2 years). Results. It was found, that the most pronounced changes in biochemical parameters of blood during obesity are observed from the side of lipid metabolism. From 34.62% of patients increased content of cholesterol in blood, 22.22% of patients, triglycerides. Glucose concentration exceeded the reference value in 25.93% of patients. The greatest changes in indicators of the oral fluid was found in triglycerides - they have a high level of 66.67% of the patients. The comparison of the indicators in the blood and oral fluid was revealed, that the increase in triglycerides in the oral fluid is accompanied by a similar trend in the blood in 22.22% of cases. Among those with a high concentration of glucose in oral fluid at 50.0% of cases revealed hyperglycemia. The evaluation of enzyme activity, despite the rather pronounced shifts in the blood, we found, that there was no significant increase in the oral fluid activity of the transaminases studied. Conclusion. Oral fluid is a useful biological material for the assessment of metabolism in patients with obesity. The most informative indicators of oral fluid to assess the state of metabolism in patients with obesity were triglycerines and glucose. The results of the study are necessary for the development of rapid systems for the diagnosis and monitoring of the effectiveness of treatment of obesity by a doctor and a patient.

Materials and methods. Survey of 100 patients aged from 18 up to 65 years receiving medicines of the first and second line by means of a scale of hospital alarm and a depression of HADS and the questionnaire of quality of life of SF-36 is conducted. Results. The obtained data have shown that medicines of the second line authentically raise physical and social indicators of quality of life; in addition, the interrelation between an emotional condition of the patient and degree of his social activity is found. Conclusion. It is established that the alarm and a depression significantly limit physical activity of the patient, reduce independent assessment by the patient of a condition of the health and quality of life of patients. It is necessary to estimate the level of alarm and a depression at patients with multiple sclerosis and to correct the phenomena of emotional instability as they influence physical health, social contacts, level of pain and, as a result, quality of life.
