Authors: Šafránková Jana Marie , Šikýř Martin 
Published: September 2018

Research background: The fundamental conclusions about the relationship be-tween personnel management and organizational performance can be also applied to personnel management in primary and secondary schools, which play an important role in the society. There is no doubt that headmasters, deputy headmasters and other school managers who want to achieve excellent performance of their schools, must pay special attention to management of all employees (including teaching and non-teaching staff) because their abilities, motivation and performance determine the desired results of schools.
Purpose of the article: The purpose of the article is to define particular categories of man-agers in Czech primary and secondary schools and specify their responsibilities and competencies in personnel management in order to propose an optimal organization of personnel management at Czech schools.
Methods: Achieving the purpose of the article is based on the analysis of available scientific literature and the results of the authors' questionnaire survey on the organization of personnel management at Czech primary and secondary schools. The survey was conducted from January to March 2017. The respondents were headmasters, deputy headmasters and other managers of Czech primary and secondary schools. The relevant data were obtained from 90 respondents. The data analysis was based on the calculation of relative frequencies and the evaluation of the dependence of responses using contingency tables and chi-square tests of independence.
Findings & Value added: The findings show that responsibilities for managing teaching and non-teaching staff at Czech schools belong not only to headmasters, but also to other managers at schools, including deputy headmasters, head teachers, heads of school clubs, heads of school canteens, educational consultants, school psychologists, treasurers, or school caretakers. Anyone who influences and directs others in the organization should be involved in personnel management and participate in various personnel management activities related to employee selection, appraisal, compensation or training. The significant competencies of headmasters and other managers in personnel and school management include managerial competencies (the ability to manage others), personal competencies (the ability to manage yourself), or professional competencies (the ability to manage the school).

Nowadays, networking within online social media platforms isn't just about swapping pictures and music, or discussing the trivial details of a night out, a TV show or a sporting event. Social media is increasingly becoming the space where professional life happens. The recent option by Face book to update user profile pages to offer a 'LinkedIn style' professional view, suggests that social media, on the whole, is becoming a medium for work as well as play.( Sophia,2009)
Recruitment is a process of finding and attracting capable applicants for employment. E-recruiting is the use of internet technology to attract candidates and aid the recruitment process. This usually means using one's own company website, a third-party job site or job board, a CV database, social media or search engine marketing. Social Media recruiting (social recruiting) is the part of e-recruiting.( Palonka et al,2013)
Social media in recruitment and selection occurs when recruitment representative view social networks platforms such as: LinkedIn, Facebook in the employment selection process leading to the acceptance or rejection of job applicants.
The goal of this research is to assessing the recent status of the usage of social media networks in recruitment and selection process in Egyptian organizations as today social media networks and platforms provide great opportunities for business and job seekers to a certain extent. By applying an exploratory study on a random sampling procedure was used to select 200 firms from different types of sectors. The respondents of this study incorporated 130 business owners and human resources managers in Egypt through online survey. The results revealed that the 54 percentage of the respondents use social media to support their recruitment effort human while 31percent don't know and plan to use it .the results revealed that LinkedIn and FB are the most social media platforms used in recruitment , also the paper surveyed some obstacles and advantages for social media recruitment.
An Intelligent Forecasting Model for Rowing
Authors: Huang Yan-Zhen , Liu Jing-Wei 
Published: September 2018

According to the current International Rowing Federation, the distance from the rowing competition is 2000 meters, the match time depending on the different items. The boating operation relies on the paddle hand of the boat to push the boat forward quickly with the work done by the paddle hand. As a result, boating wants to pass the endpoint at less time in a specified distance, and must increase the frequency of rowing per minute on the ship as a power paddle. Increasing the strength of each paddle allows the ship to paddle at the most force of each oar. Each oar hand puts forward the required quality requirements, that is, strength, speed, muscular endurance and rhythm. At present, many scholars have put forward many methods to study sports monitoring at home and abroad, but this sport is rarer in rowing.
Therefore, this study will present the intelligent prediction of rowing performance model to predict the performance of the contestants, including:

We use four weight methods to defuzzify: (a) dynamic weight forecasting, (b) equal weight, (c) sequential weight, and (d) trends weight.
Finally, the forecasting value is optimized by the adaptive adjustment method.

Finally, this study uses the public information provided by the International Rowing Alliance website as a training prediction model. The test results are compared with the weight-cutting and forecasting methods.

Authors: Bahrun Uleng , Wijaya Chelvi 
Published: September 2018

Multiple Sclerosis (MS) is an autoimmune disease that causes myelin destruction in the Central Nervous System (CNS). Characteristics of this disease are perivascular infiltration by inflammatory cells, demyelination and loss of axons, accompanied by multiple plaque formation in the brain and spinal cord. According to the National Multiple Sclerosis Society, 400,000 people suffer from MS in the United States and about 2.5 million people worldwide. The disease is usually diagnosed in patients aged 20-45 years and more often found in females than males with a ratio of 2: 1. Nevertheless, the etiology of MS is still unknown, but it is suspected that genetic and environmental factors may induce a response to central nervous system autoantigen, such as Epstein-Barr Virus (EBV) infection. It then causes edema, demyelination, axon destruction and loss of oligodendrosites, resulting in neurological deficits, plaque formation, scarring and reduced brain volume. Multiple sclerosis symptoms and signs actually vary greatly depending on the location of the lesions and the course of the various diseases. Multiple sclerosis, moreover, can be divided into four clinical categories, namely Clinically Isolated Syndrome (CIS), Relapsing Remitting Multiple Sclerosis (RRMS), Secondary Progressive Multiple Sclerosis (SPMS) and Primary Progressive Multiple Sclerosis (PPMS). Diagnosis of Multiple sclerosis is established based on clinical symptoms and supporting investigations, such as MRI, CSF and neurological examination. In CSF examination, oligoclonal bands are found in over 90% of patients, considered as one of the laboratory criteria supporting the diagnosis of MS. There are four kinds of drugs that have been approved by the FDA as disease modifying therapy for the initial treatment of MS patients, namely interferon beta-1a, subcutaneous (SC) interferon beta-1a, interferon beta-1b and glatiramer acetate In conclusion, life expectancy in MS patients is only slightly reduced and survival is related to the disability occurred.

Authors: Batskov S. S. , Inzhevatkin D. I. 
Published: September 2018

Relevance.The relevance of this study is determined by the need to correct hyperammonemia in patients with diffuse liver diseases at the pre-cirrhotic stage, since elevated levels of ammonia in the serum have toxic effects on the central nervous system, with the development of hepatic encephalopathy.Intention.To evaluate current medication options for correction of hyperammonemia in chronic non-alcoholic steatohepatitis in the liquidators of the consequences of the accident at the Chernobyl nuclear power plant (NPP) and personnel of the Federal Fire Service (FFS) of the Emercom of Russia.Methodology.34 liquidators of consequences of the accident at the Chernobyl NPP nuclear power plant and 38 employees of the FFS of the Emercom of Russia underwent clinical and laboratory studies, including ammonia levels in blood plasma by enzyme method, evaluation of microbiota disorders, and liver fibrosis grade before and after treatment with L-ornithine-Laspartate (LOLA), as well as a combination of lactulose and a course of rifaximin.Results and Discussion.After correction of hyperammonemia in patients with chronic non-alcoholic steatohepatitis – the liquidators of the consequences of the Chernobyl accident and personnel of the FFS of the Emercom of Russia, there was a decrease in the clinical manifestations of asthenovegetative and dyspeptic syndromes; the incidence of cytolytic and cholestatic syndromes. Besides, intestinal microbiota disorder decreased, as well as fibrotic changes in the liver, and the severity of intrahepatic hemodynamics disorder. In previous studies, the correction of hyperammonemia was mainly carried out with LOLA or lactulose.Conclusion.All liquidators of the consequences of the Chernobyl accident and employees of the FFS of the Emercom of Russia with chronic non-alcoholic steatohepatitis and hyperammonemia should undergo its correction. LOLA is most effective in case of non-cirrhotic portal hypertension and the development of minimal hepatic encephalopathy, and a combination of rifaximin and lactulose is most effective if the intestinal dysbiosis prevails.

Published: September 2018

Relevance.Pelvic injuries are the most dangerous and complex in treatment injuries of the skeletal system with mortality rates up to 15–18 % and up to 65 % in hemodynamically unstable victims. Continuing massive pelvic hemorrhage is the main cause of unstable hemodynamics in victims with severe pelvic injuries and requires surgical hemostasis, including endovascular embolization.Intention.To evaluate the effectiveness of diagnostic pelvic angiography (AG) and embolization as a method of surgical hemostasis in patients with polytrauma and pelvic injuries.Method.We analyzed the results of treatment of 14 patients with polytrauma and mechanical injuries of the pelvic ring, who underwent pelvic angiography (AG) at the level I trauma center (St. Petersburg, 2013–2017). The effectiveness of surgical (endovascular) hemostasis was assessed based on the systolic blood pressure (SBP) over time, the basic composition of arterial blood (pH and lactate, buffer base deficiency (BE)), duration and volume of hemotransfusions.Result and their analysis. There are statistically significant differences between the average volumes of replacement hemotransfusion before and after AG with endovascular embolization of damaged arteries, as well as between the mean lactate levels and the deficit of BE in the arterial blood. The overall mortality rate was 6 (42.8 %) cases. Three victims (21.4 %) died during the first 24 hours and 3 (21.4 %) – during the first two weeks after the trauma. The causes of death were irreversible blood loss – 3 (21.4 %), generalized infection – 1 (7.1 %), multi-organ failure – 2 (14.2 %). The average length of treatment was (52.5 ± 24.9) days.Conclusion.Angiography gives little information in patients with low SBP, so direct surgical hemostasis like pelvic packing is preferrable and may be used as a “bridge” to AG with temporary stabilization of hemodynamics.

Relevance. The probability of emergency situations in the Barents region determines the need of improvement of forces and means of rendering first and emergency medical care to victims. In September 2017 the large-scale international exercise of rescue services of Russia, Norway, Sweden, and Finland under the code name “Barents-Rescue 2017” was carried out in the Republic of Karelia. The exercise worked oved rendering first-aid and emergency medical care to victims of emergency situations.Intention. To summarize experience in preparation, rendering and result assessment of first-aid and emergency medical care to victims of emergency situations in the framework of the international exercises.Methods. Medical document analysis (hospital records, medical triage records, expert assessment records), statistical analysis of groups using Student’s t-test. The exercise involved 76 victims with injuries of various severity levels, among them 30 were of minor severity, 19 were of medium severity and 27 were of heavy severity. They received first-aid and emergency medical care by 42 rescuers and 67 health workers (doctors, paramedics, nurses) of rescue services of Russia, Norway, Sweden, and Finland. Results assessment was made on the basis of the developed hospital records, medical triage records and expert assessment records and also statistical analysis methods.Result and their analysis. The average expert assessment of a first-aid rendered by rescuers was sufficiently high and was equal to 4.6 ± 0.1 on a 5-score rating system, where 5 points means providing full assistance in accordance with the established standards of its provision. A qualitative medical triage was provided competently, the ordering of evacuation was right, life-threatening damages and injuries were properly defined. At the stage of medical evacuation all the victims were provided with full assistance, there were no divergence of diagnoses, some differences from final diagnose were permissible at the stage of medical evacuation and had no effect on victim’s condition. In addition, a part of the victims in the hospital had medical cards, where was information about the diagnoses and the measures taken. These medical documents were also analyzed in terms of the timeliness and quality of the provision of specialized medical care to injured people in the hospital.Conclusion. The results of expert assessment during the international exercise of rescue services of Barents Rescue 2017 showed that the quality of first-aid, medical triage and emergency medical care during the evacuation and also in the hospital is high enough, but there were some remarks too. Suggestions and comments were addressed to the Exercise organizing committee to improve the engagement during first-aid and medical care to victim of the emergency and they were included in the final report on the exercise.

Relevance.Persistent profuse external hemorrhage is known to be one of the main causes of death in combat casualties.Intention.To evaluate experimentally the effectiveness of new chitosan-based topical hemostatic agents (THA) in various models of profuse external arterial hemorrhage.Method.New hemostatic chitosan-based agents of Hemohit type in various pharmaceutical dosage forms (Hemohit powder, 20 g per package and Hemohit-applicator [fine chitosan powder Hemohit-A or chitosan granules Hemohit-AG 6 g in the syringe-applicator]) were assessed for effectiveness in the model of profuse external arterial hemorrhage (bevelled laceration of the femoral artery) in 10 large laboratory animals (pigs). Evaluation of the THA effectiveness was performed according to the following parameters: primary hemostasis – stopping of bleeding immediately after application of the 1st THA package and application of a pressure bandage; secondary haemostasis – stopping bleeding immediately after applying the 2nd THA package and applying a pressure bandage, if the 1st THA package is ineffective; final hemostasis – no bleeding within 3 hours of follow-up; absence / resumption of bleeding after the march test; total amount of blood loss during the experiment; survival.Result and their analysis. It was experimentally found that in the case of external profuse arterial hemorrhage the powder and the syringe-applicator provided permanent hemostasis and 100 % animal survival. In two cases out of four, a second package of Hemohit powder was required for the final stop of bleeding. The bleeding stopped due to the formation of an edge thrombus in the area of the vascular wall defect.Conclusion.Hemohit THA can effectively stop arterial bleeding. The effectiveness of applicator with local hemostats can be assessed in the proposed experimental model with a deep narrow wound canal and femoral artery damage.

Relevance. Depleted uranium (DU) is actively used in many industries. The problems of the safety of personnel employed at industrial facilities of this kind continue to remain relevant. Experimental studies have shown the toxicity of uranium compounds, especially its soluble forms.Intention. To identify immunological disorders developing after chronic exposure to low-dose depleted uranium.Methods. The study involved 30 outbred rats and 60 mice CBA. Uranyl acetate dehydrate was used as a toxicant and administered intragastrically for 120 days. The relative number of T-lymphocytes, apoptotic and necrotic cells, the production of TNF-α, IL-1, -4, -6-β, the level of circulating immune complexes, the phagocytic activity of neutrophils, delayed-type hypersensitivity reactions, and production of immunoglobulins were assessed.Results and Discussion. According to the tests on rats, phagocytic-metabolic activity of neutrophils as well as TNF-α production increased, CD4+/CD8+ ratio decreased, and the early stage apoptosis of mononuclear cells was activated after chronic exposure to uranium salts. Most detected changes were dose-dependent. In experiments on mice it was shown that uranyl acetate dehydrate at a dose of 5 mg/kg had no effect on the functional activity of immunocytes, while the index of the delayed-type hypersensitivity reaction and IgG titers increased in animals which were administered DU at a dose of 10 mg/kg.Conclusion. The results can be used to provide specialized medical care after chronic exposure to depleted uranium.
