Published: May 2021

Negative changes in the environment, leading to public pressure and environmental legislation require fundamental changes in the industrial practice of business. Survey of the environment in 22 countries found that: in half of the countries surveyed, the environment is considered to be one of the three most serious problems of concern to society. In most countries, the overwhelming number of citizens surveyed indicated that the state of the environment had an impact on their health, and an even larger proportion stated that the environment had an impact on the health of their children. The article deals with the problem of increasing the level of environmental friendliness of transportation in supply chains. With the modern requirements in the integrated green supply chain, the reduction of the harmful impact of production and logistics activities on nature should be considered at all stages of the technological cycle of product development and its promotion through the supply chain. It is determined that the key technologies for reducing the anthropogenic impact on the environment are the optimization of transport processes due to the reduction of distance during transportation at all stages of the supply chain; the increase in the use of local resources (reducing fuel costs and harmful emissions); the use of modern environmentally friendly energy-efficient vehicles. The basic principles and approaches of the consolidated cargo transportation model have been substantiated, which balances environmental and economic problems and their testing has been carried out in the supply chain of the Epicenter hypermarket chain
Contributing factors that influence on road traffic’s risk
Authors:   National University of Life and Environmental Sciences of Ukraine, Kolosok I. O.
Published: May 2021

The level of transport at safety, energy consumption, and impact on the environment in Ukraine do not meet modern requirements. In recent decades, the world has seen a sharp increase in the number of vehicles and an increase in traffic, which leads to a stolen increase in the number of traffic accidents and their negative consequences. There is a whole range of issues that need to be solved, such as high mortality and injury rates as a result of road accidents; a significant part of obsolete vehicles operated by Ukrainian carrier, that is inefficient and harm the environment; the imperfection of the transport safety management system and the absence of a single coordinating body for road safety management, which is the reason for the lack of an integrated system of state road safety management; low level of coordination of actions and institutional capacity of state authorities and local governments to plan and conduct actions in the field of road safety; the imperfection of traffic accident monitoring systems, their statistics, and risk management; ineffective approach in solving the problem of high accident rate and severity of its consequences and creating a scientific basis for activities in the field of road safety; lack of specific measurable goals to increase the level of road safety, the relevant coordinated action plan in this area; unsatisfactory technical condition of a significant number of vehicles and the lack of a system for monitoring the safety of vehicles during their operation; low level of introduction and practical application of the latest technologies and technical means of traffic organization, automated means of control and regulation of traffic; insufficient funding of measures aimed at preventing and reducing the level of accidents, reducing the number of road accidents with real consequences; low level of driver training and lack of effective control over the activities of driving schools; low level of education of the society in the field of road safety, own responsibility and observance of traffic rules, etc. The car has advantages over other types of vehicles: high mobility, relative ease of operation, the ability to deliver passengers and goods "door to door". It is these advantages of the car that are associated with the negative phenomena that accompany motorization where the lack of traffic safety is in the first place. We can name three important characteristics of modern road transport, which determine the low-level of safety: insufficient provision of road transport with appropriate in their parameters roads; insufficient isolation of traffic flows from other road users; mass driver's profession, which causes a low average level of qualification.

Authors:   National University of Life and Environmental Sciences of Ukraine, Trokhaniak V. I.
Published: May 2021

In order to ensure a normalized and uniform internal environment in the poultry house, for large productions, new ventilation systems are needed. As part of this study, numerical simulations of the lateral ventilation system in the poultry house during the winter period of the year were performed. The result is the fields of velocities, current lines and pressures in the poultry house in a 3D setting. It was found that the supply valves located at a height of 200 mm from the floor work much more efficiently than in the traditional setting at a height of 400 mm. Installation of walls on the inside of the poultry house frame, as well as reducing the height of the floor improve the aerodynamics in the poultry house.

Published: May 2021

The article analyzes the application of the latest technologies of precision seeding on the example of the use of a seeding machine with a directional metering unit. To do this, we analyzed such a parameter in agricultural production as the cost of sowing material, which affects its effectiveness. The object of the study is a sowing machine with a directional dispenser, an innovative design solution which will improve agricultural production on the basis of resource conservation. As a result of using a new design solution of the dispenser, the accuracy of the technological process of forming a regular single-grain flow is increased. The connection between the distance from the seed to the cell and the force of its suction is established. The equation of dynamics of movement of seeds and time of exposure of seeds with a cell is received. The analysis of the forces acting on the seeds when moving them by the dispenser of the directed action is carried out. Rational phases of work of the sowing device with the batcher of the directed action are substantiated and parameters of its work are defined.

Published: May 2021

Aim: The decision of admitting COVID-19 patients as inpatients is mostlydetermined by chest X-ray based diagnosis of pneumonia severity. However, prognosis of inpatients may diverge into two groups, onegroup of inpatients did not survive while another group did.

Material and Method: More than 100 COVID-19 outpatients are collected from Tokat, Turkey in three categories: outpatients, surviving inpatients, and deceased inpatients. Their blood test profiles are analyzed and compared bydimension reduction techniques and classic statistical tests.

Results: We observe that surviving inpatients share a common blood test profilewith the outpatients, whereas non-surviving inpatients aredistinctively different. The non-surviving inpatients areon average older. Among patients older than certain age, non-survivinginpatients have higher neutrophil level, lower lymphocyte level(thus higher neutrophil/lymphocyte ratio), lower calcium level,higher C-reactive-protein, sodium, whole blood cell level, andlower hemoglobin level, than the surviving patients (whether these are inpatients or outpatients).

Conclusion: Surviving status is more important than in- and out-patient statusin a patient’s cluster membership based on blood test profile. This result suggests a plan to use both X-ray diagnosis and blood testresults as a criterion to admit COVID-19 inpatients.

Authors: SİREKBASAN Serhat , SUZUK Serap
Published: May 2021

Aim: Although videos posted on YouTube are popular sources of information on public health issues, they generally need confirmation. Our aim in this study was to evaluate the content of the most viewed Turkish YouTube videos as an information source during the COVID-19 outbreak.

Material and Method: On March 26, 2021, videos containing information about the disease were searched on YouTube using the keywords 'coronavirus' and 'COVID-19'. The videos were classified as useful, misleading, personal experiences and news updates based on the type of information they contain. Inter-rater agreement was evaluated using the kappa coefficient. The total number of views, days since upload, total video time and upload source were noted.

Results: 96 of a total of 200 videos met the inclusion criteria. The total number of views of the 96 videos included was 21,598,563. 47.92% of the videos were classified as useful, 37.5% as news updates, and 6.25% as personal experiences. It was determined that 8.33% of the videos presented medically misleading information.

Coclusion: This study shows that most of the internet videos about COVID-19 on YouTube are considered as beneficial. Videos prepared by reliable sources such as academic institutions and health institutions were few. It is very important that news agencies take measures to prevent the dissemination of false information in public health emergencies and that the content of the videos they publish is correct.
Volume-based dysplasia severity index with the spheric cup method in the evaluation of adult and adolescent acetabular dysplasia
Authors: EREN Mehmet Burtaç
Published: May 2021

Introduction / Aim: Defining and treating adult and adolescent acetabular dysplasia before arthrosis develops is one of the basic principles of hip-preserving surgery. During the evaluation of cases with asymptomatic or mild symptoms, the severity of the acetabular covering deficiency directs the treatment. We attempted to find answers to two questions with our study: 1) Are the values revealed by the described measurement technique sufficient to detect acetabular dysplasia? 2) Do the criteria calculated by the current technique correlate with the well-known radiological criteria for acetabular dysplasia?

Material and Method: Eighteen hips of patients who had undergone periacetabular osteotomy evaluated by computed tomography (CT) between June 2009 and February 2019 were included in the study (Group 1, dysplasia group). Eighteen patients of similar age and sex, who had tomography examination from the pelvic region, except for orthopedic reasons, were identified between the same dates (Group 2, control group). In the tomography examinations of the patients, the entrance area of the acetabulum was determined using the multiplanar reformation (MPR) technique. Acetabulum volume and femoral head volume was calculated according to the spheric cup measurement method. Acetabular index (AI), extrusion index (EI), Sharp angle (SA), lateral center edge angle (LCEA), and anterior center edge angle (ACEA) values were calculated from direct graphy and CT scanograms of the patients.

Findings / Results: In the comparative analysis between the groups, a significant difference was observed in terms of acetabular volume, VBADSI, AI, EI, LCEA, SA, and ACEA values (p < 0.05).

Conclusion: Acetabular volume measured using the spheric cup method and the VBADSI proved to be criteria that could contribute to the diagnosis of acetabular dysplasia. It would be appropriate to measure the described method with a larger series to reveal values peculiar to specific communities.

Published: May 2021

ABSTRACT

Objective: The aim of this retrospective study is to compare the efficacy of sympathectomy and cilostazol therapy in critical limb ischemia that cannot be revascularized.

Material and Method: This study was retrospectively conducted on 30 patients who underwent lumbar sympathectomy (Group 1) and received cilostazol treatment (Group 2) between January 2017 and August 2020. Demographic data, comorbidity, complications, wound healing, walking distance, and pain scale records of the patients were determined by examining the hospital registry system and statistical analysis was performed.

Results: In the study, no significant difference was found between the two groups in terms of walking distance and ischemic pain in the statistical analysis of the data before treatment, at the 3rd, 6th, 12th, and 24th months (p> 0.05). However, a statistically significant difference was found between the pre-treatment data and the data at the 3rd, 6th, 12th, and 24th months in both Group 1 and Group 2 in terms of walking distance and ischemic pain (p˂0.001 ). In the time periods followed in both groups, it was observed that there was an increase in walking distance and a decrease in ischemic pain.

Conclusion: Cilostazol treatment may be preferred as a good alternative treatment method compared to lumbar sympathectomy in critical leg ischemia.

Keywords: Critical leg ischemia; sympathectomy; cilostazol

Sharing data is of great importance for research in medical sciences. It is the basis for reproducibility and reuse of already generated outcomes in new projects and in new contexts. FAIR data principles are the basics for sharing data. The Leipzig Health Atlas (LHA) platform follows these principles and provides data, describing metadata, and models that have been implemented in novel software tools and are available as demonstrators. LHA reuses and extends three different major components that have been previously developed by other projects. The SEEK management platform is the foundation providing a repository for archiving, presenting and secure sharing a wide range of publication results, such as published reports, (bio)medical data as well as interactive models and tools. The LHA Data Portal manages study metadata and data allowing to search for data of interest. Finally, PhenoMan is an ontological framework for phenotype modelling. This paper describes the interrelation of these three components. In particular, we use the PhenoMan to, firstly, model and represent phenotypes within the LHA platform. Then, secondly, the ontological phenotype representation can be used to generate search queries that are executed by the LHA Data Portal. The PhenoMan generates the queries in a novel domain specific query language (SDQL), which is specific for data management systems based on CDISC ODM standard, such as the LHA Data Portal. Our approach was successfully applied to represent phenotypes in the Leipzig Health Atlas with the possibility to execute corresponding queries within the LHA Data Portal.
openEHR Mapper – A Tool to Fuse Clinical and Genomic Data Using the openEHR Standard
Authors: Reimer Niklas , Ulrich Hannes , Busch Hauke , Kock-Schoppenhauer Ann-Kristin , Ingenerf Josef
Published: May 2021

Precision medicine is an emerging and important field for health care. Molecular tumor boards use a combination of clinical and molecular data, such as somatic tumor mutations to decide on personalized therapies for patients who have run out of standard treatment options. Personalized treatment decisions require clinical data from the hospital information system and mutation data to be accessible in a structured way. Here we introduce an open data platform to meet these requirements. We use the openEHR standard to create an expert-curated data model that is stored in a vendor-neutral format. Clinical and molecular patient data is integrated into cBioPortal, a warehousing solution for cancer genomic studies that is extended for use in clinical routine for molecular tumor boards. For data integration, we developed openEHR Mapper, a tool that allows to (i) process input data, (ii) communicate with the openEHR repository, and (iii) export the data to cBioPortal. We benchmarked the mapper performance using XML and JSON as serialization format and added caching capabilities as well as multi-threading to the openEHR Mapper.

Published: May 2021

Against the background of increasing numbers of indications for Cochlea implants (CIs), there is an increasing need for a CI outcome prediction tool to assist the process of deciding on the best possible treatment solution for each individual patient prior to intervention. The hearing outcome depends on several features in cochlear structure, the influence of which is not entirely known as yet. In preparation for surgical planning a preoperative CT scan is recorded. The overall goal is the feature extraction and prediction of the hearing outcome only based on this conventional CT data. Therefore, the aim of our research work for this paper is the preprocessing of the conventional CT data and a following segmentation of the human cochlea. The great challenge is the very small size of the cochlea in combination with a fairly bad resolution. For a better distinction between cochlea and surrounding tissue, the data has to be rotated in a way the typical cochlea shape is observable. Afterwards, a segmentation can be performed which enables a feature detection. We can show the effectiveness of our method compared to results in literature which were based on CT data with a much higher resolution. A further study with a much larger amount of data is planned.

Published: May 2021

In this study, an attempt has been made to differentiate Alzheimer’s Disease (AD) stages in structural Magnetic Resonance (MR) images using single inception module network. For this, T1-weighted MR brain images of AD, mild cognitive impairment and Normal Controls (NC) are obtained from a public database. From the images, significant features are extracted and classified using an inception module network. The performance of the model is computed and analyzed for different input image sizes. Results show that the single inception module is able to classify AD stages using MR images. The end-to-end network differentiates AD from NC with 85% precision. The model is found to be effective for varied sizes of input images. Since the proposed approach is able to categorize AD stages, single inception module networks could be used for the automated AD diagnosis with minimum medical expertise.

Published: May 2021

Adolescent Idiopathic Scoliosis (AIS) is lifetime disorder indicated by the abnormal spinal curvature, and it is usually detected in children and adolescents. Traditional radiographic assessment of scoliosis is time-consuming and unreliable due to high variability in images and manual interpretation. Vertebrae localization and centerline extraction from a biplanar X-ray is essential for pathological diagnosis, treatment planning, and decision making. The aim of this paper is to develop a fully automated framework to provide correct evaluation of anatomical landmarks and to extract vertebral and intervertebral discs’ centroids. By knowing coordinates of each centroid, developed framework will estimate 2D deformity curve (centerline) called Middle Spinal Alignment (MSA) in frontal plane. By analyzing the MSA lines and deformity segments, many deformity parameters can be calculated which include vertebral transpositions, Cobb angles, apex vertebra position, etc., for planning spinal correction strategies and monitoring.

During the COVID-19 pandemic, the number of visits in emergency departments (ED) worldwide decreased significantly based on several studies. This study aims to compare the patient flow in the emergency surgery department during the COVID-19 pandemic and a control period in the emergency department of a public tertiary care hospital in Greece. The overall patient flow reduction regarding the ED visits between the two examined periods was 49.07%. The emergency surgery department’s corresponding visits were 235 and 552, respectively, which indicated an overall patient flow decrease of 57.43%. Chi-square analysis showed that age groups and ambulance use had statistically significant associations with the periods examined. An independent samples t-test was applied and deduced that the average patient’s age was statistically significantly higher in the COVID-19 pandemic than in the non-pandemic period. By analyzing hospital information system data, useful conclusions can be drawn to prepare a surgical emergency unit better and optimize resource allocation in a healthcare facility in similar critical situations.
Ontology-Based Personalized Cognitive Behavioural Plans for Patients with Mild Depression
Authors: Nair Aditi , Abidi Syed Sibte Raza , Van Woensel William , Abidi Samina
Published: May 2021

Cognitive Behavioural Therapy (CBT) is an action-oriented psychotherapy that combines cognitive and behavioural techniques for psychosocial treatment for depression, and is considered by many to be the golden standard in psychotherapy. More recently, computerized CBT (CCBT) has been deployed to help increase availability and access to this evidence-based therapy. In this vein, a CBT ontology, as a shared common understanding of the domain, can facilitate the aggregation, verification, and operationalization of computerized CBT knowledge. Moreover, as opposed to black-box applications, ontology-enabled systems allow recommended, evidence-based treatment interventions to be traced back to the corresponding psychological concepts. We used a Knowledge Management approach to synthesize and computerize CBT knowledge from multiple sources into a CBT ontology, which allows generating personalized action plans for treating mild depression, using the Web Ontology Language (OWL) and Semantic Web Rule Language (SWRL). We performed a formative evaluation of the CBT ontology in terms of its completeness, consistency, and conciseness.

Published: May 2021

The main challenge in the pathway analysis of cancer treatments is the complexity of the process. Process mining is one of the approaches that can be used to visualize and analyze these complex pathways. In this study, our purpose was to use process mining to explore variations in the treatment pathways of endometrial cancer. We extracted patient data from a hospital information system, created the process model, and analyzed the variations of the 62-day pathway from a General Practitioner referral to the first treatment in the hospital. We also analyzed the variations based on three different criteria: the type of the first treatment, the age at diagnosis, and the year of diagnosis. This approach should be of interest to others dealing with complex medical and healthcare processes.

Published: May 2021

Alzheimer Care Trainer (ACT) is an interactive narrative simulation for caregivers of patients with Alzheimer’s disease. It aims to support family caregivers by letting them practice difficult situations of daily life in a training environment. In order to ensure its accessibility to its target audience, which may be unfamiliar with new technologies, we have created a tutorial. The aim of the tutorial is to teach users the main mechanics of the simulation. Considered to be an introductory level to ACT, it is built in 2 parts, a dirigiste first part and an exploratory, second part. Several tutorial elements, such as context-sensitive information or a help page, have been integrated. The evaluation of the tutorial by 14 participants revealed that interaction mechanics were well understood although the state of the visual element remains confusing. Generated positive affects were stronger than the negative ones and most of the participants were confident to play the game after the tutorial. Ensuring accessibility to all populations is essential especially when targeting seniors. A well-conceived tutorial has the potential to familiarize users with our intervention, reducing the risk of excluding people that could benefit from it.

As the COVID-19 pandemic evolves, the accompanying infodemic is being amplified through social media and has challenged effective response. The WHO Early AI-supported Response with Social Listening (EARS) is a platform that summarizes real-time information about how people are talking about COVID-19 in public spaces online in 20 pilot countries and in four languages. The aim of the platform is to better integrate social listening with other data sources and analyses that can inform infodemic response.

Aim: to evaluate the long-term clinical efficacy of the combined (laser plus surgical) minimally invasive technique for rhegmatogenous retinal detachment (RRD). Patients and Methods: treatment results of 41 patients (41 eyes) with local RRD resulting from horseshoe retinal tear were analyzed. All patients underwent wide-field optical coherence tomography (OCT) to localize and measure pathological vitreoretinal adhesions at the site of retinal tear. The next step was a combined laser surgical procedure that included Nd: YAG dissection of pathological vitreoretinal adhesion zone, pneumatic retinopexy (10% C3F8), and barrier laser retinal photocoagulation (LRP) after reattachment. Postoperatively, eye exams were performed after 3 and 7 days, 3, 6, 12, 18, and 24 months. Results: complete reattachment was achieved in 38 patients (92.7%) on day 2 or 3. No reattachment was seen in three patients (7.3%); of them, subretinal gas migration was observed in two patients (4.9%), and partial reattachment was detected in one patient (2.4%) with pseudophakia. Recurrent RRD occurred in 3 patients (7.9%) because of new inferior retinal breaks. In four patients (10.5%), postoperative wide-field OCT of the area of the initial retinal tear performed after reattachment revealed additional pathological vitreoretinal adhesions in the adjacent areas (that were not identified preoperatively). These patients underwent additional LRP around the areas of pathological vitreoretinal adhesions. No recurrent RRDs were seen during follow-up. Conclusion: combined minimally invasive laser surgical technique for local PPDs demonstrated high efficacy (92.7%). This technique was the effective in local retinal detachment resulting from a single superior horseshoe retinal tear in patients with crystalline lens. In some cases, pseudophakia is a technical obstacle to this procedure. Postoperative wide-field OCT is recommended to detect additional pathological vitreoretinal adhesions and to perform LRP around them to reduce the risks of recurrent RRDs greatly.

A magyar és olasz fegyveres erők jelenléte nemzetközi missziókban és műveletekben
Authors: Váradi Gréta Vanessza , Göblyös Bence
Published: May 2021

A jelenlegi biztonsági környezetben Olaszország az egyik  legmeghatározóbb európai ország a nemzetközi  missziókban és műveletekben való részvétel terén. A  tanulmány célja annak vizsgálata, hogy a gyakran használt  presenzialismo kifejezés alkalmazható-e Magyarország  részvételére is. A főbb nemzetközi szervezetek misszióihoz  és műveleteihez való hozzájárulás vizsgálatával a cél annak  bizonyítása, hogy Magyarország részvétele az adott ország  erejével és lehetőségeivel arányosan összehasonlítható-e vagy sem Olaszország tevékenységeivel. Az egyik fő  megállapítás az, hogy a két ország érdeklődési területe  szinte azonos. A két ország egyetért abban is, hogy a  transzatlanti régió biztonságának megőrzésében a NATO-t  tartják a legfontosabb partnernek. Mindkét nemzet fegyveres erőiben reform folyik, de ezek nem vezethetnek a missziókban és műveletekben való részvétel gyengüléséhez. Annak ellenére, hogy Olaszország  részvétele túl szembetűnő; megállapítottuk, hogy  Magyarország arányosan nem marad el jelentősen  Olaszország hozzájárulásától.

Three substituted aryl esters of orthophosphoric acid are the base component of fire-resistant fluids used in the lubricating and electro-hydraulic control system at steam and gas turbines of power plants. In this paper, we studied the possibility of improving the physicochemical and performance properties of phosphates, which are made of the raw materials available in the Russian Federation: phenol and 4-tert-butylphenol by reducing the content of an undesirable component - unsubstituted triphenyl phosphate, which is particularly vulnerable towards water. According to the results of the work, the conclusions were made: - a decrease in the content of triphenyl phosphate to a level of 1% and below leads to some improvement (reduction) of the air release time and an increase in the hydrolytic stability (represented as reducing the change in acid number after prolonged contact with water) of the fire-resistant fluid based on mixed esters. The degree of change of these properties is quantified. - it is possible to achieve the minimum content of triphenyl phosphate by changing the phosphorylation technology. By carrying out the process stepwise, the possibility of the interaction of phosphorus oxychloride with unsubstituted phenol is substantially eliminated, that is why there is almost no probability of an undesirable component formation in the resulting mixture of esters.

The article presents the characteristics of characteristic oils of the Apsheron oil and gas region, as well as the hydrocarbon composition of light and oil fractions. Oils of the Apsheron oil and gas region in terms of light fractions, sulfur content, and density are comparable to marketing grades of oils. The standards for prices are: graded crude oil WTI, Light Sweet, Brent, and Russian oils Sokol, Urals, Siberian Light are approaching them. We have studied in detail the yields and hydrocarbon composition of light and oil fractions of oils from the Apsheron oil and gas region. To obtain oils with a high viscosity index, studies were carried out to change the structure of oil fractions using hydrogen using the example of oil fractions of Azeri oil. Due to the significant content of aromatic hydrocarbons, schemes for the processing of oil fractions have been developed, including selective purification of distillates, dewaxing (except for Guneshli oil), as well as hydrocatalytic treatment in a severe mode in the presence of industrial Russian catalysts. As a result, it was possible to obtain API group I oils, according to the viscosity classification corresponding to SAE 20 and SAE 30. Thus, a study of the qualities and hydrocarbon composition of oils from the Absheron oil and gas region showed that these oils are characterized by a high content of light fractions, low density, and low sulfur content. According to these indicators, these oils correspond to the marker oils. In order to obtain base oils with a viscosity index of ≥90 and an aromatic hydrocarbon content of ≥10, a traditional refining method was used: selective refining, dewaxing, and severe hydrotreating.
