Venous Stasis Leg Ulcers: A Review
Authors: Gaus David 
Published: February 2020

Chronic venous stasis ulcers (CVSU) of the lower extremity affect up to 5% of the population over 65 years and 1.5% of the general population. CVSU is caused by chronic venous disease produced by venous hypertension. Venous hypertension results from valvular incompetence within the deep venous system, or by the obstruction of venous outflow. Both of these mechanisms produce poor venous return. Additionally, poor mobility and decreased calf muscle pump function are thought to be contributing factors. Life-long use of compressive therapy is indicated in patients with chronic venous disease in lower extremities. It reduces ambulatory venous pressure. These include bandaging systems, garments (stockings), or devices.
Features of the district bodies of the Ministry of Internal Affairs in Siberia in the 19th century
Authors: Konovalov Igor A. 
Published: February 2020

The subject. The reorganization of the district police in Siberia in the second half of the XIX century is comprehensively examined in the article on the basis of pre-revolutionary legislation. Special attention is paid to the organizational and legal issues of the activities and structure of the district police.The purpose of the paper is to confirm or disprove hypothesis that the practice of implementing legislative innovations on the status of internal affairs bodies in Siberia in the 19th century was characterized by systematic seizures and violations.The theoretical and methodological basis of the study includes the principles of historical knowledge – objectivity, historicism, alternative and social approach. These principles let use an unbiased approach to the analysis of the studied problems, as well as a critical attitude to the sources.The main results and scope of their application. The author concludes that the powers of the police bodies in the region had their own specifics and were much broader than in the central provinces of the Russian Empire. Reorganization of the general police in Siberia in the second half of the XIX century changed the structure and method of staffing the Ministry of Internal Affairs. It was not principled, but rather external. Returning to the forgotten traditions of the organization and activities of the police, it is important to take full account of the historical experience that has been accumulated over the centuries. It is also necessary, taking into account modern realities, to take a fresh look at the already known facts and events in order to overcome old myths and misconceptions and prevent the birth of new ones.Conclusions. The police reform of 1867 in Siberia left almost unchanged the limits of power, the distribution of duties, procedures, responsibility and accountability of the general police. A large range of prerogatives remained for the police. In addition, many police officers continued to work the old-fashioned way, trying to ignore changes in the current legislation. The legislator failed to put the Siberian internal Affairs bodies in the strict framework of the law, it was recognized by local leaders and visiting auditors.
Online voting as an element of cybersecurity of megacities
Authors: Ivanova Xenia A. 
Published: February 2020

The subject. The author explores the possibility of online voting during the elections from the perspective of urban security.The purpose of the paper is to confirm or disprove hypothesis that introduction of online voting in the elections in large cities contributes to the growth of the electorate’s confidence and reduction of absenteeism, but only if cybersecurity of metropolises is ensured.The methodology of the study includes general scientific methods (analysis, synthesis, description) and the method of comparative law.The main results and scope of their application. The very essence of online voting involves the use of a dedicated Internet platform and digital devices. This method has many advantages, including the ability to attract many people, the convenience and reliability of the whole process, as well as the automatic calculation of results. However, the issue of online voting in large cities directly affects the problem of ensuring their cybersecurity. Electronic voting can be subject to certain risks like any Internet procedure. Some of them have their own offline counterparts, such as the sale of votes. Others are unique to the digital environment, such as cyber violations and DDoS-attacks.Conclusions. Electronic voting helps to solve the problem of low voters’ turnout, unites communities, universities, companies and people. This new process must be protected from any potential threats to security.An inefficient voter authentication procedure can adversely affect the reliability of the entire online voting system. Hacking the authentication system can lead to fraud and theft of data and votes. The blockchain system provides effective protection against such hacks and cyberattacks. It would be effective if it was possible to download a special anti-virus program from the election commission website to clean the user's computer from malicious content or at least check the presence of viral content. The license key of such a program may be valid only for the period of the elections. The decision against forcing an electronic vote for a particular candidate can be made by an online voting system that allows you to change your choice several times. We need well-thought-out training and advanced training programmes for state and municipal employees, including programmes for initial technical training, to reduce security risks. It is necessary to train possible users of the online voting system, since the security of a computer or smartphone, the absence of virus programs, as well as the timeliness of voting are in the area of responsibility of online voters. Online voting may not be the only way a voter can express his or her will. It is always necessary to keep the possibility of classical voting by paper ballots.

Published: February 2020

Pasca berakhirnya perang dingin, fokus negara-negara di dunia ini tidak lagi terhadap peningkatan kekuatan militer untuk menghadapi ancaman dari negara lain melainkan lebih kepada peningkatan perekonomian negara dimana persaingan dunia mulai beralih dari militer ke ekonomi. Dalam rangka melindungi dan mempertahankan salah satu sektor ekonomi strategis nya, Indonesia dan Malaysia yang semula berkompetisi dalam pasar CPO Internasional justru membuat kerjasama dengan membentuk Dewan Sawit atau CPOPC (Council of Palm Oil Producing Countries). Dewan tersebut dibuat untuk mempromosikan serta meningkatkan daya saing minyak kelapa sawit yang kerap kali mendapat sorotan negatif dari negara lain, terutama dari negara-negara Eropa. Sebagai dua negara produsen terbesar sawit dunia, Indonesia dan Malaysia cenderung pasif dalam menentukan harga, dan standar sawit mereka sendiri dan kerap mendapat kecaman terhadap industri sawitnya yang dinilai tidak ramah lingkungan.

Published: February 2020

Abstract: This study assesses the feasibility of co-management arrangements in managing scalloped spiny lobster (Panulirus homarus) fishery in the Sultanate of Oman. The appraisal is conducted using various indicators involving pre-implementation phase and institutional characteristics and substantiated by findings of the review of relevant local and global literature and the results of a structured questionnaire survey conducted during 9-28 June, 2013 with 536 randomly selected fishers from three Governorates namely Sharqiyah, Al-Wusta, and Dhofar. The former method helps identifying suitable assessment criteria and provides indication of readiness while the later method helps determining primary stakeholders’ perceived views on various aspects of regulatory measures and co-management arrangements. While findings related to fishers’ commitments, willingness to support government decisions, willingness to participate in co-operative research, and preference for co-operative decision-making are promising, institutional weaknesses identified under the category of ‘interactive organization’, ‘resource ownership and control’, ‘existence of planned process’, and ‘diversity’ should be of major concerns for policy-makers in moving towards co-management arrangements. Based on the findings some policy implications are also discussed.

Published: February 2020

Aims
Uninterrupted anticoagulation is recommended during the ablation of atrial fibrillation. This meta-analysis compared the safety and efficacy of uninterrupted direct oral anticoagulants (DOACs) to uninterrupted vitamin K antagonists (VKAs) during atrial fibrillation ablation.

Methods
The meta-analysis included eligible randomized controlled trials from 2009 to 2019. Odds ratios (ORs) and 95% confidence intervals were pooled using a random effects model and a sensitivity analysis was performed by sequentially removing one study or DOAC at a time.

Results
Six studies were included; 1288 received DOAC and 1081 VKA. Pooled ORs indicated a lower nonsignificant incidence in DOACs vs. VKA of composite outcome of major bleeding, stroke, or transient ischemic attack, and mortality (0.69; 0.28–1.71; 31 vs. 45 events), major bleeding alone (0.66; 0.30–1.47; 27 vs. 41 events), and cardiac tamponade (0.56; 0.21–1.45; eight vs. 13 events) with a slightly higher occurrence of minor bleeding (1.17; 0.89–1.56; 139 vs. 106 events) and silent cerebral thromboembolic events (1.12; 0.75–1.66; 72 vs. 58 among 442 and 376 patients performing MRI study). Sensitivity analyses confirmed overall results: pooled ORs ranged from 0.56 to 1.00 for the composite outcome and from 0.54 to 0.92 for major bleedings.

Conclusion
Uninterrupted DOAC is a safe and effective alternative to uninterrupted VKA during atrial fibrillation ablation.

The Transcarpathian plain is the northeastern part of the large Middle Danube lowland in the Transcarpathian region. The length of the plain is 80–90 km, the width is 22–23 km, the height is 102–120 m asl. Within the Transcarpathian plain stands out the Berehiv hills, represented by single volcanic mountains of 300-500 m altitude (Black Mountain – 568 m asl, Shalanka – 372 m asl. and other).
The Transcarpathian plain is located mainly on the right bank of the Tisza River. Soil-forming rocks are mostly acidic. The climate of the Transcarpathian plain is humid, temperate and continental.
The spontaneous flora of the Transcarpathian plain consists of 1209 species of higher vascular plants. Depending on the ecological and coenotic affiliation of flora species to the main zonal vegetation types, seven florencoenotypes were identified in the territory of the studied region: 1) Immoral (Nemoralophyton) – 375 coenoelements (33.33% of the total number of species). In the composition of the Nemoralophyton the florencoenosvites are distinguished: a) oak-hornbeam (Querceto-carpinetophytum) – 130 coenoelements (10.75%); b) helio-quercetal (Quercetophytum) – 171 coenoelements (14.14%); c) fagetal (Fagetophytum) – 74 coenoelements (6.12%); 2) Meadow (Pratophyton) – 220 coenoelements (18.2%). As a part of the Pratophyton the florencoenosvites are: а) flood-meadow (Humidopratophytum) – 92 coenoelements (8.02%); b) land-meadow (Mesopratophytum) – 132 coenoelements (10.92%); 3) Meadow-steppe (Prato-Steppophyton) – 164 coenoelements (13.56%); 4) Xerothermic shrub (Xerothamnophyton) – 32 coenoelements (2.65% ); 5) Marsh (Paludophyton) – 31 coenoelements (2.56%); 6) Hygro-hydrophilic (Hyhro-Hydrophyton) – 129 coenoelements (10.67%). As a part of the Hygro-Hydrophyton the florencoenosvites are: a) coastal-water (Hygrophytum) – 79 coenoelements (6.53%); b) aqueous (Hygrophytum) – 50 coenoelements (4.13%); 7) Synanthropic (Synantropophyton) – 285 coenoelements (23.57%). In the composition of the Syntantropophyton the florencenosvites are as follows: a) vegetative vegetation (Segetalophytum) – 132 coenoelements (10.92%) and b) ruderal vegetation (Ruderalophytum) – 153 coenoelements (12.65%).
The results of the analysis of the ecological-coenotic structure of the flora of the Transcarpathian plain showed that the leading position is occupied by species of the immoral florenceonotype (Nemoralophyton) (with the predominance of the helio-quercetal florencoenosvita (Quercetophytum); meadow (Pratophyton) (with the predominance of land-meadow florencoenosvita (Mesopratophytum) and meadow-steppe (Prato-Steppophyton) florencoenotypes.
The distribution of species by major ecological-coenotic groups reflect the features of the main genetic types of vegetation, climatic, edaphic conditions and terrain of the territory under study

The study is concerned with the study of natural and landscape conditions of the territory of the Nature Reserve "Medobory", and its historical significance in formation of the biotic diversity of Western Ukraine.
It focuses on the research into the territory and formation of the Nature Reserve "Medobory", which covers over 9 000 ha in the central Tovtry.
Moreover, the work highlights the ongoing studies of zoobiota in the area, and points out its significance for preserving the regional fauna (by the end of 2019 the following species were recorded: 1 species of freshwater sponge, 79 species of molluscum, 32 species of centipedes, 2170 species of insects, 15 species of fish, 11 species of amphibians, 7 species of reptiles, 197 species of birds, 55 species of mammals).
The study also provides a detailed analysis of international lists of threatened species valid for the territory of Ukraine, and the species from the Red Book of Ukraine (the 3rd edition); as a result it identifies certain species to be under protection, such as 41 species of mammals, 187 species of birds, 18 species of amphibian and reptiles, 4 species of fish, 30 species of arthopods, 1 species of molluscum. Altogether, there are 281 species in the international lists of endangered species, which makes 11 % of the reliably ascertained fauna variety of the conservation area (2566 species). Except for the arthopods, which are scarcely represented in the international lists, there are more than 63 % of the traced representatives of fauna vertebrates under protection, according to the international lists of endangered species (251 species out of 396 known ones). For many of the animal species the natural forest stand of Medobory is a refugium, where they survived the ice age, and in some of the localities certain rare relict species have survived into the present time.
On the territory of the Nature Reserve Medobory the following animal species enlisted internationally have been registered: IUCN Red List - 18 species, the European Red Lists of species - 28 species, the Bern Convention – 256 species, the Bonn Convention – 102 species,the Bern Convention – 256 species, the Washington Convention – 37 species. 83 animal species of the Reserve and the surrounding territory call for protection since they are listed in the Red Book of Ukraine.

In science vicasol is known to be relative to the energy and antioxidant systems of tissues closely related to the biosynthesis and oxidation of fatty acids. This effect may cause changes in the fatty acid composition of tissues, and numerous works on the positive effect of quinones and their derivatives on the myocardial function, suggest that the proper dose and feeding can increase the stability and productivity of poultry. The given was aims to study the effect of vicasol on the fatty acid composition of goose myocardium.
Myocardium was chosen as a biological object. Biological material was collected every 7 days throughout the period from the 21st to the 35th day of ontogeny, characterized by the state of physiological tension of geese. Feeding of geese with vicasol at a dose of 0.7 mg / kg body weight began with the 3rd day of ontogeny. Fatty acid analysis in myocardial tissues was performed by gas-liquid chromatography, pre-fabric samples were processed with the method by Palmer (1971) to obtain tissue lipid extracts.
According to the results of the study, due to various changes in the content of the entire spectrum of fatty acids of the tissue during the experiment - the use of vicasol causes a slight increase in the unsaturation and the total content of unsaturated fatty acids in the myocardium of geese. These fluctuations are realized depending on the physiological state of the body. where vicasol can stimulate both the biosynthesis processes of individual fatty acids and their mitochondrial and microsomal oxidation, as evidenced by multidirectional reliable changes in the content of their entire spectrum. In particular, on the 21st day, the content of docosopentaenoic acid increased by 36.3% whereas the content of docosohexaenoic and linolenic acids decreased by an average of 21–24%, on the 28th day the content of eicosatetraic and docosahexaenoic acids increased whereas the content of the linoleic acids dropped by 22.6% in control groups. On the 35th day, the content of basic unsaturated fatty acids: palmitooleic, linoleic, linolenic and docosohexaenoic acids increased in the tissue under the influence of vicasol with complete depletion of docosopentaenoic acid. These fluctuations in fatty acid composition cause a slight increase in the total content of unsaturated fatty acids and increase the unsaturation of myocardial lipids on the 28th and 35th days of ontogeny of geese. Based on previous results regarding the antioxidant state of myocardium affected by vicasol and the given findings, which prove changes in the content of the entire spectrum of fatty acids during the selected ontogeny, vicasol can be used in poultry farming as a tool to improve the quality and the resilience of poultry.

Published: February 2020

The incidence of Diabetes Mellitus is increasing worldwide, with almost 1/3 of adults being affected. It is the major contributor to the morbidity of a man with its multi-organ system complications. Control of blood glucose levels is vital to decrease organ damage and complications. Routine diagnostic tests conducted are blood glucose, lipid profile, renal function tests, HbA1c, and insulin assays with a baseline CBC (Complete Blood Count). HbA1c values continue to be the gold standard for the assessment of glycemic control. The RDW (Red Cell Distribution Width) is a parameter of Complete Blood Count. Several studies have shown elevated RDW values in patients with poor glycemic control and as an early marker for Diabetic nephropathy and cardiovascular complications. 610 patients with type 2 Diabetes Mellitus attending the Diabetic Clinic in Saveetha Medical College were included in a cross-sectional study to compare HbA1c values with RDW values with age and gender. The ratio of patients with poor HbA1c levels: acceptable HbA1c levels of glycemic control was1:4 in the age group 25 years and below. The ratio rose to 1:1 in the 36-45 years age group with a reversal of ratio to 4:1 in patients >65years of age. There was a significant correlation between the values of HbA1c with age - with the number of patients increasing with age and showing elevated HbA1c levels. There was no significant correlation between the values of RDW and age. There was a significant positive correlation between HbA1c and RDW- (p = 0.003, < 0.05 standard). For patients with HbA1c values between 6.2- 6-8 %, there was a particularly strong positive correlation with RDW values. In conclusion, there was a significant positive correlation between values of RDW and HbA1c, which emphasis that RDW is a good predictive factor for glycemic control.
