Orthopaedic complications of falls in elderly patients: a brief review
Authors: Suyasa I Ketut
Published: April 2020

Falls are frequent and often cause morbidity, mortality, and disability that require regular nursing. Most of these falls are associated with one or more identifiable risk factors, such as weakness, unsteady gait, confusion and medication use. Usually, it occurs due to a combination of multiple risk factors, such as imbalance, degenerative diseases, porotic bone, and metabolic disturbances. Though in the orthopaedic field, falls will most often result in injury such as femoral neck and proximal humerus fractures, all other parts of the body may also be affected due to various mechanisms of injury. As a disabling phenomenon, fractures due to falls in elderly may then proceed to series of complications, from early to late complications, from local (such as nonunion, muscle atrophy, disuse osteoporosis, etc) to systemic complications (such as pressure sores, pneumonia, ulcers, urinary tract infection, ileus, etc).Â  Therefore, prevention will play a critical role in this particular situation.
Physiological peculiarities of thrombocyte activity of candidates into masters of sports in athletics of preadult age
Authors: Medvedev Ilya Nikolayevich
Published: April 2020

Introduction: Physiologically, platelets are an important component of homeostasis of the whole body and blood system. However, not everything is clear with platelet activity of young healthy persons who have systematic exercises, particularly masters of sportsâ€™ candidate. Its in vitro and in vivo should be studied further.Aim: The aims of this investigation are to find out the abnormalities of thrombocyte activity of master of sportsâ€™ candidate in athletics of young age and compare them with thrombocyte level of young people who avoided exercises during their lifetime. Â Through modulation of their activity, they increase capillaries' perfusion and thereby metabolism in tissues.Materials and methods: In our investigation group we took 125 candidates into masters of sports in athletics of preadult age regularly exercising and participating in competitions of different levels. Control group was consisted of 141 healthy youths having avoided exercises during their lifetime. Biochemical, hematological and statistical methods are applied.Results: Athlete were found to have stable normal functional platelet activity. For subjects between 18 and 22 years, their platelets aggregation was on low level and had no reliable variations related to their stable low sensitivity to inductors. Decreased platelet activity causes conservation in athletes' blood of some quantity of circulating thrombocyte aggregates. It makes positive impact on microcirculation in organs of athlete having regular athletic exercises. Avoidance of exercise in young age promotes gradual rise of thrombocyte activity. Masters of sportsâ€™ in athletics candidate who had intensive muscle activities are characterized by persistence of stable low platelet activity. It provides low quantity of active platelets and their circulating aggregates in blood. Those young persons, who avoided exercises, are noted to have elevated platelet activity with a tendency increased aggregate formation.Conclusion: Masters of sports in athleticsâ€™ candidate doing intensive muscle activity are characterized by preservation of stable not high platelet activity caused by low content of active platelets and their circulating aggregates. Avoiding exercises in young people are noted to have caused the increase of platelet activity with a tendency to cause platelet aggregation.

Background: Healthy, intelligent, and highly competitive children are the asset of a nation. Indonesia as one of the developing countries which level of fish consumption is still low, including children fish intake. Children fish consumption in Surakarta, Central Java Province has potential to improve. Growth and brain development persist in childhood and adolescence at 9-10 years. That age range is the beginning of the peak growth (growth spurt) that requires the intake of fat and protein to support the growth and development of the brain and fish is a potent food source of protein and omega-3 fatty acids.Aim: This study aims to analyze the relationship between fish consumption frequency and fish type with children intelligence level at aged 9-10 years.Method: The design of this study was cross-sectional involving 112 elementary school children grade 4 in Surakarta, Central Java, Indonesia. Data were collected using questionnaires, 1 x 24-hour food recall form, semi-quantitative FFQ (Frequency Food Questionnaire), anthropometry, and intelligence level using Culture Fair Intelligence Test (CFIT-2A) method. The results were analyzed by multivariate analysis with multiple logistic regression.Results: Multiple logistic regression analysis on the intelligence level of children aged 9-10 years showed that the frequency of fish consumption has a value of p = 0.170 and fish species has a value of p = 0.259, while confounding factors in the form of mother education and income of parents have their respective p-value of 0.011 and 0.171.Conclusion: There is no significant correlation between the frequency of fish consumption and type of fish to the intelligence level of children aged 9-10 years (p> 0,05). However, the probability of subjects whose frequency of consumption of fish >3 times/week to have intelligence in the intelligent category greater than 1.81 times the subject consuming fish â‰¤3 times/week, after controlling maternal education factors and income parents.

Authors: Bangun Edwin Calvin , Prasetyo Eko , Oley Maximillian Christian
Published: April 2020

Background: Increased level of interleukin 6 (IL-6) in patients with severe traumatic brain injury (TBI) has been documented, yet studies of its ability to predict the outcome based on the Leukocyte is limited and lacks clarity. This study aims to evaluate the relationship between serum level of IL 6 and Leukocyte among patients with severe TBI.Methods: Twenty patients admitted consecutively to the emergency room (ER) with severe TBI were included in this observational, cross-sectional, single-centre study. Venous blood sample for IL 6 and leukocyte was performed less than 24 hours of trauma in the Intensive Care Unit.Â  Age and gender were also recorded. Variable selection was run in stepwise forward fashion. Correlational odds models were conducted to assess how change in Leukocyte is related to levels of IL 6. Data were analysed using SPSS version 17 for Windows.Results: The average age of respondents was 32.45Â±10.71 years old and mostly males (85%). The Glasgow Coma Scale (GCS) was predominant in score 8 (45%). The mean value of IL-6 was 22.00Â±4.66 pg/ml and 22.53Â±8.11 x 103 in leucocyte. The weak insignificant correlation was found between IL-6 and blood peripheral leucocyte using Pearson Correlation test (r = - 0.290; p = 0.108)Conclusion: The recent findings suggest that there is no correlation between IL 6 levels and Leukocyte in patients with severe TBI.

Authors: Prihadi Johannes Cansius , Tampubolon Kevin Anthony Glorius , Dicky Dicky
Published: April 2020

Introduction: Penile fracture is a rare urological emergency that needs immediate repair. It is usually caused by trauma in its origin, whether during sexual intercourse, exotic self-inflicted, fall, or vehicle-related. Tunica albuginea and/or corpus cavernosa are severed, it can sometimes be accompanied by rupture of the urethra. Immediate surgical repair should be done as soon as possible to prevent further complication.Case Presentation: A 52 years old male comes with swelling and severe pain on his penis 14 hours following sexual intercourse with his partner. No blood in the external meatal nor hematuria was present, and there were no abnormal passing of urine complained. Immediate repair of the corpus cavernosum was performed. The penis was degloved and the corporal tear was closed using absorbable suture. 8 hours following surgery, the patient had a morning erection and no early signs of complication observed.Conclusion: Immediate surgical repair should be presented after penile fracture was diagnosed. Emergency surgical repair can preserve voiding and sexual function.

Published: April 2020

Background: Nutritional status of school-age children is influenced by several factors, e.g., nutrition intake, hormone, and underlying disease. Mercury, as a pollutant from artisanal and small scale gold mining (ASGM), inhibits thyroxin production-metabolism regulating hormone. The objective of this study was to evaluate the effect of iodine status and nutritional intake on nutritional status of school-age children in ASGM area.Methods: Study design was cross sectional. There were two groups; case group was school-age children exposed by mercury from ASGM area from Sekotong subdistrict, and control group was school-age children in Narmada subdistrict. Sixty two children from ASGM were enrolled, and fifty two children from the Narmada subdistrict. Iodine status was assessed by measured urine iodine excretion using acid digestion method; nutrition intake assessed by using recall 24 hours; nutritional status by measured anthropometry. Correlation between nutritional and iodine status was examined by using Spearmanâ€™ test.Results: Nutritional status of case group found 45.1 % were stunted and 27.4 % were underweight. Control group found 13.4 % Â stunted and 9.6 % underweight. Iodine status of case group: 3.9 %Â  deficient and 68.6 % at risk of iodine-induced hyperthyroidism, the control group was found that 3.8 % inadequate and 72.8 % at risk of iodine-induced hyperthyroidism. Iodine intake both groups were under RDA value that of the case group was 8.3 Âµg/day, and the control group was 11.5 Âµg/day. All nutrition supporting growth did not meet the RDA value.Â  Spearmanâ€™s test result was p=0.56.Conclusion: Iodine status did not correlate with the nutritional status of children in ASGM area.

Authors: Martyasari Ni Wayan Riyani , Andayani Yayuk , Hajrin Wahida
Published: April 2020

Background: Tekelan leaves (Chromolaena odorata) has been commonly used traditionally as a medicine. It is known that Tekelan leaves have bioactivity as an antibacterial. These leaves have antibacterial activity for both gram-positive and negative bacteria so that it can be made for semi-solid preparation namely hand sanitiser gel (HSG). This study aims to determine the optimum concentration of HSG base with TLE and determine the physical characteristics of the optimum formula.Methods: Sample extraction was done by maceration method with 96% of ethanol (1:10). Dechlorophyllation with n-hexane also used to separate the chlorophyll and to get a better colour of extract while it formulated in gel form. Optimisation of the gel is conducted with the simplex lattice design (SLD) method. SLD method is available in Design-Expert software. The method was designed to optimise the formula with different concentration of different component (Gliserin, TEA, and Carbopol) so it can produce the optimum formula. The evaluation of HSG involves spreadability test, sticky power and pH test. Furthermore, the acceptability evaluation was done by 20 respondents.Results: The optimum gel base formula is consists of 1.860% glycerin, 2.901% TEA, and 0.739% carbopol with spreadability 3.673 cm, sticky power 1.181 s, and pH 7.187. The acceptability of the C. odorata HSG also compared with one of the commercial HSG. The percentage of acceptability of C. odorata HSG is 75.25% and 80.25% for the commercial HSG.Conclusion: HSGÂ preparationsÂ of TLEÂ which are formulated using optimum base formula have good physical properties.

Authors: Kloping Yudhistira Pradnyan , Himawan Budi , Balti Dimas Rio
Published: April 2020

Background: The most common sexual problem affecting the general population of men is Erectile Dysfunction (ED) with a global estimated number of over 100 million. It affects the biological, psychological, and social aspect of life which can cause frustration, depression, and anxiety. Unfortunately, the attention towards the disease in Indonesia is often overlooked as evidenced by the lack of studies regarding the prevalence and risk factors for the disease. This study aims to evaluate possible risk factors of Erectile Dysfunction among elderly males in Lamongan, East Java.Methods: This is a quantitative study with an analytical observational design, performed using a case-control approach. Respondents consisted of male inpatients as well as outpatients aged 40 years or more in Ngimbang General Hospital evaluated using the International Index of Erectile Function (IIEF) questionnaire. The patientâ€™s comorbid data are taken from the Medical Record to ensure proper diagnosis. The acquired data are then analysed using the ordinal logistic regression method.Results: A total of 174 men were evaluated. There are 62 people with no ED (35.6%), 39 people with mild ED (22.4%), 35 people with mild to moderate ED (20.1%), 16 people with moderate ED (9.2%), and 22 people with severe ED (12.6%). Significant risk factors are older age (OR: 1.29; CI: 1.23-1.37), Diabetes (OR: 6.56; CI: 2.77-15.56), and hypertension (OR: 5.19; CI: 2.27-11.88) (all, p < 0.05); whereas dyslipidemia and smoking habit are insignificant (p>0.05).Conclusion: Age, diabetes, and hypertension are significant risk factors for Erectile Dysfunction.
Clinical and plain x-ray findings of spinal metastases: a retrospective study of pathologically-confirmed cases
Authors: Suyasa I Ketut , Astawa Ni Made Puspa Dewi
Published: April 2020

Background: Malignancy of breast, prostate, and lung contribute to metastatic bone disease, and the metastases are mostly located in the spine. Spinal metastases may involve the spinal cord, leptomeninges, epidural space and also the bone itself. Therefore, proper imaging is needed in early detection and diagnosis of spinal metastasis. This study aimed to perform the clinical and plain x-ray findings in patients with spinal metastasis.Â  Â Method: A retrospective study was conducted on 28 spine pathological fracture patients with neurologic deficits who underwent surgical intervention in Sanglah General Hospital during a year. We evaluated the present symptoms, neurological status (Frankel score), pathological reports by plain x-ray findings, metastases cell type by histological assessment, and extension of mass expansion on MRI. A total of 20 cases that met the inclusion criteria were evaluated.Result: Most patients suffer from pathologic fracture on thoracic spine level, followed by lumbosacral level and none on cervical spine level. The compressive fracture was a major finding on plain x-ray. The extradural lesions account for most of the MRI findings, followed by intradural/extramedullary and intramedullary lesion. Primary tumours that lead to bone metastases in this serial-cases are prostate, breast, cervix, kidney and lung cancer, respectively.Conclusion: Thoracic spine is the most common spinal metastases manifestation. Conventional plain x-ray is the most initial modality to evaluate systemic neoplasia patients with spinal pain, although it is not a sensitive indicator to identify the presence and extent of metastatic involvement.
Axial Triangle of the Maxillary Sinus, and its Surgical Implication With the Position of Maxillary Sinus Septa During Sinus Floor Elevation: A CBCT Analysis
Authors: Jung Junho , Park Jung Soo , Hong Seoung-Jin , Kim Gyu-Tae , Kwon Yong-Dae
Published: April 2020

The aim of this study was to measure the convexity of the lateral wall of the maxillary (Mx) sinus and identify the locational distribution of antral septa in relation to the zygomaticomaxillary buttress (ZMB), in order to suggest another anatomical consideration and surgical modification of sinus floor elevation procedures. This study was designed as a cross-sectional study, and a total of 134 patients and 161 sinuses containing edentulous alveolar ridges were analyzed. The angle between the anterior and lateral walls of the Mx sinus (lateral sinus angle [LSA]), and the angle between the midpalatal line and the anterior sinus wall (anterior sinus angle [ASA]) were measured. Mean LSAs and ASAs were 105.9° ± 9.86° and 58.4° ± 6.43°, respectively. No significant difference between left and right sides was found (LSA, P = .420; right = 105.5° ± 9.27°; left = 105.5° ± 9.27° and ASA, P = .564; right = 57.9° ± 6.80°; left = 58.8° ± 6.02°). The prevalence of septa was 37.3%, and it was most frequently noted in the second molar region (32.8%), followed by the first molar (20.9%), retromolar (16.4%), and second premolar regions (14.9%). Septa were most frequently located posterior to the ZMB (49.2%), while ZMB was mostly located in the first molar region (66.4%). Narrow LSAs may complicate the surgical approach to the posterior maxilla, especially when sinus elevation should be used in the second molar region. Considering the occasional presence of antral septa, membrane elevation may be complicated when a septum is encountered during the procedure. These results suggest that 3-dimensional examination of the convexity of the Mx sinus should be performed preoperatively to choose proper surgical techniques and minimize surgical complications.
What Is the Role of Endodontic Predisposing Factors in Early Implant Failure?
Authors: Sisli Selen Nihal , Pektas Zafer Ozgur
Published: April 2020

We aimed to investigate a possible relationship between early implant failure (EIF) and an adjacent root canal–treated tooth and/or tooth with a periapical lesion (PL), considering the duration between implantation and root canal treatment (RCT). The importance of prior RCT and/or presence of a PL before implantation was also investigated. A total of 810 implants from 342 patients were included and scored according to the implant failure before abutment connection, adjacent root canal treated teeth, adjacent teeth without RCT, no adjacent teeth, adjacent teeth with PL, extraction of teeth with PL, and/or RCT before implantation. The durations between the extraction and implantation and between RCT and implantation adjacent to the root canal–treated teeth were recorded. The time from the RCT of adjacent teeth to implant placement was categorized into 5 groups: less than 4 weeks before implantation, 4–12 weeks before implantation, at least 12 weeks before implantation, within 4 weeks after implantation, and at least 4 weeks after implantation. Among the endodontic predictors, a prior PL on the tooth extracted was associated with an increased risk of EIF (P < .05, odds ratio: 4.37; 95% confidence interval: 1.604–11.891). Furthermore, EIF was more likely to occur when the RCT of an adjacent tooth was performed within 4 weeks of implantation (P < .05). Additional investigations with larger sample sizes are necessary to validate our findings.
Three-Dimensional Finite Element Analysis of Osseointegrated Implants Placed in Bone of Different Densities With Cemented Fixed Prosthetic Restoration
Authors: Chidambaravalli Kasthuri , Krishnan Vinod
Published: April 2020

A key factor for a successful dental implant is the manner in which stresses are transferred to the surrounding bone. Strength of bone is directly related to its density. Maximum stresses are reported to be incurred by the crestal cortical bone surrounding the implant. Displacement of implants is significantly higher in soft cancellous bone than dense bone. Implants are often placed in bone of different densities to support fixed dental prostheses. This study was aimed at assessing stress and deformation generated by osseointegrated implants placed in bone of different densities on a cemented fixed prosthesis when subjected to static and dynamic loading.

A 3-dimensional finite element analysis was done on a computer-aided design model simulating maxillary bone segment with 2 different bone densities (D2 and D4). The effect of loading was evaluated at the implant–bone interface, implant–abutment interface, abutment, implant abutment connecting screw, cementing medium, and fixed prosthesis. Stresses were calculated using von Mises criteria calibrated in megapascals and deformation in millimeters. These were represented in color-coded maps from blue to red (showing minimum to maximum stress/deformation), depicted as contour lines with different colors connecting stress/deformation points. The study found greater von Mises stress in D2 than D4 bone, and in D2 bone the component with higher stress was the implant. Deformation was greater in D4 than D2 bone, and in D4 bone the abutment-prosthesis interface showed more deformation.

Published: April 2020

The purpose of this retrospective study was to determine survival and peri-implant marginal bone loss of short and ultra-short implants placed in the posterior mandible. A total of 98 patients received 201 locking-taper implants between January 2014 and January 2015. Implants were placed with a 2-stage approach and restored with single crowns. Clinical and radiographic examinations were performed at 3-year recall appointments. At that time, the proportion of implant survival by length, and variations of crestal bone levels (mean crestal bone loss and mean apical shift of the “first bone-to-implant contact point” position) were assessed. Significance level was set at 0.05. The total number of implants examined 36 months after loading included: 71 implants, 8.0 mm in length; 82 implants, 6.0 mm in length; and 48 implants, 5.0 mm in length. Five implants failed. The overall proportion of survival was 97.51%, with 98.59% for the 8.0-mm implants, 97.56% for the 6.0-mm implants, and 95.83% for the 5.0-mm implants. No statistically significant differences were found among the groups regarding implant survival (P = .73), mean crestal bone loss (P = .31), or mean apical shift of the “first bone-to-implant contact point” position (P = .36). Single-crown short and ultra-short implants may offer predictable outcomes in the atrophic posterior mandibular regions, though further investigations with longer follow-up evaluations are necessary to validate our results.
Socket Preservation Using Xenograft Does Not Impair Implant Primary Stability in Sheep: Clinical, Histological, and Histomorphometric Study
Authors: Mayer Yaniv , Ginesin Ofir , Zigdon-Giladi Hadar
Published: April 2020

Implant primary stability, which depends mainly on the amount and quality of bone, is important for implant survival. Socket preservation aims to reduce bone volumetric changes after tooth extraction. This animal study aims to examine whether preserving a ridge by using xenograft impairs the primary stability of the implant. Eighteen artificial bone defects were prepared in 4 sheep (5- and 8-mm length). Defects were randomly grafted with xenografts: Bio-Oss (BO), Bio-Active bone (BB), or left for natural healing (control). After 8 weeks, bone biopsy was harvested and dental implants installed. During installation, peak insertion torque (IT) was measured by hand ratchet, and primary stability by the Osstell method. Histomorphometric analysis showed a higher percentage of new bone formation in the naturally healed defects compared to sites with xenograft (control: 68.66 ± 4.5%, BB: 48.75 ± 4.34%, BO: 50.33 ± 4.0%). Connective tissue portion was higher in the BO and BB groups compared to control (44.25 ± 2.98%, 41 ± 6%, and 31.33 ± 4.5%, P < .05, respectively). Residual grafting material was similar in BO and BB (7 ± 2.44%, 8.66 ± 2.1%, respectively). Mean IT and implant stability quotient (ISQ) values were not statistically different among the groups. A positive correlation was found between IT and ISQ (r = 0.65, P = 0). In conclusion, previously grafted defects with xenograft did not influence primary stability and implant insertion torque in delayed implant placement. These results may be attributed to a relatively high bone fill of the defect (∼50%) 2 months after grafting.
Guided Implant Placement Using an Internally Cooling Surgical Template: A Technical Note
Authors: Alevizakos Vasilios , Mitov Gergo , von See Constantin
Published: April 2020

Cooling irrigation during implant bed preparation is mandatory to avoid overheating. Due to the surgical guide design, external cooling systems do not reach the point of entry of the implant burr. Here, a new technique for irrigation during guided implant surgery for direct rinse of the burr is described. Using computer-aided design/computer-aided manufacturing additive technology, a pin of a cooling pipe was designed and implemented in a surgical guide template. The implant bed preparation was performed while the cooling pipe was connected to the surgical guide. During surgery, the irrigation solution was directly rinsing the burr at the point of entry through the irrigation channel. The use of a cooling surgical guide seems to improve the cooling of the bone during implant bed preparation. This might lead to less thermal effect of bone cells. However, systematic studies are needed to confirm the observations of the presented case report.

Published: April 2020

The relevance of the research is caused by the importance of maintaining the competitiveness of the national economy in the conditions of forming and developing digital economy. The research objective is to analyze obstacles to the effective implementation of the strategy of digitalization of the domestic economy and factors that hinder it, which, in our opinion, are not given enough attention. The authors consider the influence of institutional features of modern Russian economy on economic behavior of business. The adverse institutional environment is considered the main reason which is slowing down digitalization of Russian economy and development of digital technologies by business. The analysis of the modern Russian institutional environment, in particular its important factors such as vulnerability of ownership rights and low institutional trust to the power, allows to draw the conclusion that they lead to the emergence and consolidation of new economic and behavioral norms, which become alternative mechanisms of the economic choice at implementing economic interests. Thearticle substantiates such a modern phenomenon of Russian economy as institutional alienation of reproduction functions of business at the social production. In this connection, there is a necessary to develop state actions for digitalization of economy at their coordination with a complex of actions for improving the institutional business environment, which is slowing down effective socio-economic development of the national economy.

Its consistent solution requires not only searching for ways and tools to consolidate standard and a number of experimental diagnostic procedures, but also verifying their analytical abilities taking into account the specifics of the economic space of the center-peripheral systems of agricultural-industrial regions. Theaim of the study is to inventory and characterize the possibilities and disadvantages of existing methodological approaches to the analysis and assessment of regional socio-economic differentiation in the center-periphery system. This will allow not only to identify the strengths and weaknesses of the available relevant methods, but also on this basis to move to the formulation of specific requirements for a modern analytical and diagnostic system for detecting problems of development of peripheral localities, which should take into account the need to screen and monitor a number of new diagnostic areas of analysis. The article considers a number of analytical and diagnostic areas, which are not reflected in theoretical provisions in any of the scientific directions of conceptual support of functioning and development of peripheral territories. Combining them in order to enhance the “permeability” of methods and tools of a system-diagnostic approach to peripheral research involves the development of a special methodology.

Purpose. Emissions from mine ventilation system can create intensive atmosphere air pollution. As a rule, a huge amount of dust from mine fan enters atmosphere low layers. An important task is the development of methods to assess levels of the atmosphere pollution near mines and settlements. To solve this problem it is important to have physically proved mathematical models. Nowadays to predict the atmosphere pollution near settlements which are effected by mine fan the empirical model OND–86 is used. This model does not take into account many important physical factors. So, the purpose of this study is the development of quick computing mathematical model to predict the atmosphere pollution in case of dust emissions from mine fan. Methodology. To predict levels of the atmosphere pollution in case of mine fan work 3D equation of dust convective – diffusive flow was used. This equation takes into account gravity fallout, wind velocity, atmosphere turbulent diffusion, location of dust emission source. To sole modeling equation the implicit difference scheme of splitting was used. Findings. Developed mathematical model allows quick prediction of the level of atmosphere pollution in case of dust emissions from mine ventilation fan. The models allow to obtain zones of contamination near settlements which are situated in vicinity of mine. Originality. The developed mathematical model takes into account a number of physical factors, which at the present time are not considered on the days when prediction of the atmosphere pollution in settlements near mine is carried out. Practical value. On the basis of the developed mathematical model program code was created. This code can be used for evaluation of atmosphere pollution in settlements which are effected mine fan emissions.

Purpose. The article is aimed to analyze the main differences of the Ukrainian railway infrastructure, comparing both with the neighboring countries at the western border and with the countries to which the 1520 mm track can be drawn, taking into account the direction of the main freight traffic volume from East to West. It is also aimed to provide quantitative and qualitative assessment of technical compatibility and other indicators of railway networks in relation to the territory of Ukraine. Methodology. To obtain data on infrastructure and transportation volumes in the mentioned countries, a world literature review on this subject was performed using full-text and statistical databases. The methodology involves the analysis and systematization of the information obtained to establish relevant dependencies, conclusions and proposals. Findings. It is proved that international transportations through the territory of Ukraine have certain features. Changing the railway track standards at the border with European countries forces to search for the most rational routes for cargo transportation (taking into account the distance, technical condition and parameters of international transport corridors, delivery speed, etc.) and rational technologies for the goods transfer at border points, which make it possible to take these transportations to an innovative path of development. Originality. Based on the positive experience, first of all of the European Union countries, the authors have shown that with the presence of efficient transport network and a developed system of cargo transfer at the points of changing the railway infrastructure standards, both domestic and transit freight traffic volumes significantly increase, which makes it possible to increase the attractiveness of the country in the international transportation system. Practical value. Based on the obtained results, it is shown that the Ukrainian railway transport can be integrated into the European transport network, providing the modernization of track, engineering structures and other facilities included in the railway infrastructure, the introduction of new rolling stock, which will ensure passenger transportations by day trains with the required comfort and maximal set speed.

Purpose. It is a very important issue to be able to determine the accurate particle degradation of railway ballast material. There are three different – but connecting – methodology for that: 1) full scale field tests, 2) full scale or reduced scale laboratory tests, 3) computer modelling, mainly with discrete element method (DEM). Options no. 1 and no. 2 need a lot of time and money, but for option no. 3 sophisticated software is needed that can consider the accurate micromechanical characteristics of ballast bed material. Methodology. In this paper the authors summarize their results related to modelling, having applied a software that uses DEM for calculation, as well as laboratory tests, namely uniaxial compression tests with reduced scale and computer tomography. Findings. The authors obtained the results that the uniaxial compression test in laboratory was able to be modelled by DEM software with an initial precision but in the future should be specified. The results are certified by measurements performed by computer tomography method. Originality. It is a very complicated issue to model the particle breakage of railway ballast not only particle movements in DEM software. There are many available software packages at the ‘market’, e.g. PFC, EDEM, YADE. Some of them are quite expensive, the others can be controlled by significantly difficult manner (special programming technique is needed, command line, etc.) The authors applied not only laboratory loading tests, but sophisticated computer tomography for their research. Practical value The results can be useful for railway engineering area. This article is a part of a PhD research at Szechenyi Istvan University, the PhD student is Erika Juhász. Her aim is to develop a method to be able to determine the more accurate ballast breakage, as well as develop assessment methodology related to special measurement techniques (e.g. GOM techniques, computer tomography, etc.). The publishing of this paper was supported by ÚNKP–19-3–I–SZE–13 project.
