A Comparison of Different Short-Term Macroeconomic Forecasting Models: Evidence from Armenia
Authors: Poghosyan Karen 
Published: May 2018

Abstract
We evaluate the forecasting performance of four competing models for short-term macroeconomic forecasting: the traditional VAR, small scale Bayesian VAR, Factor Augmented VAR and Bayesian Factor Augmented VAR models. Using Armenian quarterly actual macroeconomic time series from 1996Q1 – 2014Q4, we estimate parameters of four competing models. Based on the out-of-sample recursive forecast evaluations and using root mean squared error (RMSE) criterion we conclude that small scale Bayesian VAR and Bayesian Factor Augmented VAR models are more suitable for short-term forecasting than traditional unrestricted VAR model.

The Valve Gear Systems Timing Parameters Identification for Marine Diesel Engines Diagnostics / Identyfikacja Parametrów Układów Rozrządu Silników Okrętowych Dla Potrzeb Diagnostyki
Authors: Lus Tomasz 
Published: May 2018

Abstract
In the paper results of studies that aim was to develop a diagnostic method for high-speed marine diesel engines are presented. Polish Navy is operating significant number of engines of this type also on board of submarines. Engines of this type do not have indicator valves, which complicates the assessment of combustion process and their technical condition. Polish Naval Academy in Gdynia for years has been developing methods of diagnosing marine internal combustion engines. In recent years, a diagnostic method for high-speed marine diesel engines based on the analysis of envelope of vibration accelerations generated by the valve gear mechanism and fuel system has been developed. Some tests results made on Mercedes-Maybach MB820 engines used on Kobben class submarines are presented in the paper.

Published: May 2018

Abstract
Under the influence of globalization and state integration processes, the importance of a border as a barrier is gradually decreasing. Borderlands are still perceived as specific phenomena, however, not only in terms of historical development but especially in the context of their changing impact on the daily lives of their inhabitants. Along with EU enlargement, the de-bordering process has also become significant in many countries where the borderland played an important role in the past. These include the V4 countries, whose borderlands are the object of this research. In this article we analyze these areas on the basis of selected socio-economic indicators, with a focus on change in the period 2001–2011. As indicated by the Analysis of Variance, the results show the significantly differentiated development of the borderlands, in terms of the individual values of indicators both within the borderland of the EU member states, as well as along the external border of the EU.
Fine and ultrafine TiO2 particles in aerosol in Kraków (Poland)
Authors: Wilczyńska-Michalik Wanda , Rzeźnikiewicz Kamil , Pietras Bartłomiej , Michalik Marek 
Published: May 2018

Abstract
During single particle analysis of aerosol in Kraków (Poland) we noticed a new component, that is, aggregates of TiO2 particles. These aggregates are from 0.5 to 4 μm and are composed of individual particles whose size typically varies from between 100 and 350 nm. Smaller particles (below 100 nm) also occur. TiO2 particles are relatively abundant in the summer. The size distribution of the particles corresponds to “pigmentary” TiO2, which indicates that they could be derived from paints and building materials. TiO2 particles were not previously identified in aerosol samples in Kraków, and therefore this phenomenon is likely to be related to the common usage of new building materials and paints. A review of the literature suggests that TiO2 particles, especially within the nanosize range, could result in health and environmental impacts; however, evaluation of the actual threat is difficult.
Study Concerning Characterization of Some Recycled Concrete Aggregates

Published: May 2018

Abstract
Using recycled concrete aggregates (RCA) is a matter of high priority in the construction industry worldwide. In countries like the Netherlands, Denmark, Germany, USA, Japan, France recycled concrete aggregates obtained from demolition are valorized up to 90%, mainly for road construction and less in the manufacture of new concrete.
Recycled concrete aggregates (RCA) generally result from a two-stage crushing of the concrete obtained from demolition followed by the screening and removal of contaminants (wood, plastic, metal, ceramics etc.). The literature review showed that the recycled aggregates concrete (RAC) are less resistant, with 15 to 40% versus concrete obtained using natural aggregates. The factors that play a role in the reducing of mechanical resistance are presented and analyzed in this study.
This paper presents a study on the use of recycled aggregates, from a concrete of specified class, to acquire new cement concrete with different percentages of recycled aggregates. In order to evaluate the influence upon the properties of the new concrete obtained, recycled aggregates have been characterized in terms of the granulosity, the granule shape, the absorption of water, behavior to the Los Angeles test, the content of attached mortar etc.
Keep calm and carry on: A crisis communication study of Cadbury and McDonalds
Authors: Telang Achyut , Deshpande Amruta 
Published: May 2018

Abstract
Many organizations, at some point or another, have to face a crisis situation. In that scenario, the way in which the organization communicates makes or breaks the organization’s success in dealing with the crisis. Especially after the emergence of the social media, the impact of crisis communication on the process of successful crisis management has become even greater than before. Organizations have to take the initiative, to be proactive and create a plan for crisis communication. This paper is focused on the comparative study of the communication approaches followed by Cadbury and McDonalds during a period when the companies were dealing with a crisis. The findings of the content analysis show that a company should respond to the crisis as quickly as possible to avoid loss in terms of sales. The initial statement of the companies during a crisis should be clear, positive and through the right channel to help the company regain its reputation on the market. Advertising is the best way to convey the message across the world because the crisis situation that has come up in one market can soon catch-up in the other markets where the company operates. The company has to connect with the consumers on emotional grounds because the crisis breaks down the faith of the consumers in the company. The recovery actions that support the statements also play an important role during the crisis situation. By following the above-mentioned communication strategies, organizations can achieve damage control as well as turn the crisis into an opportunity to grow.

Published: May 2018

Abstract
Introduction. A transient ischemic attack (TIA) is an acute episode of temporary neurologic dysfunction that typically lasts less than an hour. Atherosclerotic plaques in the carotid arteries may cause TIA by lumen stenosis or plaque-related thromboembolism. The aim of this paper was to analyze the changes of the carotid arteries in patients with TIA and associated risk factors.
Methods. A retrospective analysis of 62 TIA patients was performed. Color duplex sonography of the carotid arteries and risk factor assessment was carried out in all patients.
Results. We analyzed 15(24%) females and 47(76%) males with TIA, aged 45-79 years. The most frequent risk factor was hypertension, present in 57 patients (91.9%). The most common findings of the extracranial segments of the carotid arteries were atheromatous plaques present in 25.8% and low-grade stenosis (40-59%) visualized in 24.1% of patients. Multiple plaques predominated, mostly localized in the region of bifurcation and the beginning of the internal carotid artery (67.7%), with irregular surface (in 58.1%), heterogenous structure (70.9%) and mostly hypoechogenic (46.8%).
Conclusion. These data have demonstrated a significant relationship between carotid artery ultrasound plaque characteristics and TIA occurrence. That is why color duplex sonography of the carotid arteries should be carried out in all TIA patients and risk factors should be evaluated, in order to take appropriate therapeutic measures for prevention of definitive stroke.
The possibilities of stem cell application in regenerative medicine
Authors: Galiniak Sabina , Krawczyk-Merć Izabela , Pedrycz Agnieszka 
Published: May 2018

Abstract
Stem cells are characterized by their ability to self-renew and differentiate into various cell types. They offer great potential for a wide range of applications, however, medical studies on the use of embryonal stem cells are largely limited to bioethical issues searching for alternative sources of stem cells, which include isolating cells from adult organisms or inducing pluripotentiality of somatic cells by administration of transcription factors. Nowadays, stem cells are used to study the mechanisms of cell differentiation and treat diseases that are commonly considered to be incurable, such as diabetes and neurodegenerative diseases, as well as enable regeneration of skin damage and myocardium. This review introduces the subject of stem cells, their sources and application in regenerative medicine.
Partnership as a legal form of exercising the profession of midwife
Authors: Sadowska Monika , Wdowiak Artur 
Published: May 2018

Abstract

Introduction. The profession of midwife belongs to the medical ones. In the Polish legal system, the definition it is not of a legislative nature. It refers to liberal professions associated with practical medical knowledge. However, the profession of midwife has also been included in the catalog of liberal professions under the commercial law, and the legislature allows the practice of midwife in the form of a partnership.
Nevertheless, the majority of midwives working in Poland is employed on the basis of an employment relationship and a civil law agreement, while exercising practice in the form of partnership is not a frequent choice.

Aim. The purpose of this article is to profile the midwife partnership, including the approximation of its essence and purpose, as well as the rights and obligations of the partner, and discussion of the terms and conditions of the company's medical business.

Summary. Compared to other commercial companies, a limited liability partnership company is an attractive legal form for exercising the profession of midwife, primarily because of the partner's liability for the company's obligations. At the same time, the midwife partnership company, by combining both a reduction of personal responsibility, transparent representation with the use of possibility of appointing a board, and the possibility of accumulating financial and intellectual capital, meets the demands of the free services market and growing competition, thereby fostering service quality.

Published: May 2018

Abstract

Aim. Assessment of the effectiveness of therapeutic education conducted by nurses working in the internal medicine wards in patients with diagnosed type 2 diabetes in the context of the sense of coherence.

Material and methods. The survey was carried out among 100 nurses working in the internal medicine wards. In the assessment of the effectiveness of therapeutic education, the authors' survey questionnaire was used, whereas the sense of coherence of the surveyed nurses was measured by means of SOC-29 life orientation questionnaire.

Results. Therapeutic education conducted by nurses who completed postgraduate studies was a more planned process and covered more topics. A high sense of coherence correlates with a wider range of educational interactions. Over half of the surveyed nurses (56%) showed an average sense of coherence and 44% - a high sense of coherence, what was significant for the effectiveness of conducted health education. The number of encountered factors hindering the education of patients depends on the level of the sense of coherence. The surveyed with a high sense of coherence face more difficulties than those with an average sense of coherence.

Conclusions. The nurses declaring the implementation of therapeutic education of patients used the knowledge gained during postgraduate education. Those who completed such studies covered a wider range of topics during the education process. A high sense of coherence is an important factor, significant in the implementation of the educational function of the nurse, and the improvement of the effectiveness of this kind of education can be achieved thanks to wider consideration of these issues at universities and postgraduate education.

Published: May 2018

Abstract
Field experiments on the susceptibility of onion to thrips infestation were carried out in 2012 and 2013. The investigation used 18 cultivars and 5 breeding lines of Allium cepa, and the species A. fistulosum and A. roylei. In 2012 A. fistulosum was one of the most infested plants, whereas in 2013 infestation was no more than average. The most infested cultivars of A. cepa were ‘Efekt’, ‘Alonso F1’, ‘Alibaba’ and ‘Wama’ and the ‘NOE5’ breeding line. In 2012 the extent of damage ranged from 12 to 55%, in 2013 from 20 to 30%. The ‘NOE2’, ‘NOE3’ and ‘Wama’ cultivars were the most seriously damaged by thrips. Leaf damage to A. fistulosum was minimal. No damage was caused to the wild species A. roylei by feeding onion thrips.

Published: May 2018

Abstract
In the last decades, substantial strides have been made in the diagnosis, treatment, and prevention of blood diseases. The new drugs to be used in combination with cytostatic therapy have been developed, based on increased understanding of the biology of neoplasia. The diagnosis of several diseases is based exclusively on cytogenetic and molecular analysis which has become a part of routine diagnostic management. Moreover, molecular definition has allowed the introduction of therapy targeted at molecular change characteristic for a given disease. The introduction of novel agents for the treatment of hematological disorders has resulted in a great improvement in response rate and median survival.
The aim of this study is to show advances and possible future directions in the treatment of chosen hematological malignancies during the recent decades.
The new era in the treatment of deep vein occlusion
Authors: Kęsik Jan Jakub , Terlecki Piotr , Feldo Marcin , Pietura Radosław , Zubilewicz Tomasz 
Published: May 2018

Abstract
A non-invasive, conservative treatment has been a standard in treating acute and chronic deep vein thrombosis. This treatment turned out to be ineffective, particularly in the hip area. Also, it was demonstrated that it does not influence the frequency of manifestations of post-thrombotic syndrome. Previous attempts to surgically reconstruct deep veins, unlike arteries reconstruction, yielded no positive results and also increased hemorrhagic and embolic complications. Currently, already in the period of the acute thrombosis of deep veins, the methods of early re-canalization, both with the application of targeted thrombolisis, as well as of pharmacomechanical methods, are applied.
Thanks to a wide array of image examination methods applied in pre-operational and intra-operational diagnostics optimum, it is possible to plan a revascularising treatment in the sick individuals suffering from the already developed manifestations of the post-thrombotic syndrome.
The development of endovascular methods, made possible thanks both to the surgeons’ experience in the re-canalization field, as well as constant improvements of stents dedicated to the venous system, allowed for effective use of these techniques in curing the occlusion of deep veins. It was the case with the arterial system and works here as well. Applying the hybrid proceeding, combining opened techniques and endovascular ones, works very well in selected cases.

Abstract

Introduction. Uterine fibroids are the most frequent benign tumors affecting sexual organs in women. It is estimated that they affect 20% of the female population, with the frequency in pregnant women ranging between 0.1-5%. In spite of the progress in the field of medicine, the actual cause of uterine fibroids has yet to be discovered.

Aim. Analysis of the recent methods of dealing with uterine fibroids during pregnancy.

Material and methods. A review of literature about dealing with pregnant, lying-in and parturient women suffering from uterine fibroids.

Results. The research studies by Aydeniz, Vergani, Rice showed that cesarean sections are much more frequent in pregnant women with uterine fibroids than in control group (52.9% vs 27.9%; 23% vs 12%; 35.1% vs 21.5%). However, it was shown that the rate of cesarean sections was much higher in women with uterine fibroids located in the lower part of the uterus than in the fundus uteri (respectively 39% and 18%). Also, the rate increased when the diameter of the fibroid exceeded 5 cm, unlike in case of those smaller than 5 cm (respectively 35% and 17%).

Conclusions. 1. The number of cesarean sections in women with uterine fibroids is higher than in control group. 2. The frequency of cesarean sections in pregnancies with uterine fibroids depends on their position and size. 3. There is no relationship between the number of complications and the amount of fibroids in pregnant women. 4. There is no agreement concerning the recommendations for removing the fibroid during cesarean section.

Abstract
The first recorded road fatality happened over 140 years ago. Since then, road accidents have become one of the main causes of concern in almost every country in the world. Nowadays, fatal motor vehicle crashes occur at an interval of 50 seconds and injuries happen every two seconds. According to the WHO, the world road death toll is nearly 1.3 million and 20-50 million of people have been badly injured in road accidents and usually require long and expensive treatment. This paper looks at the issue of road accidents in the earliest days of the automotive industry. The article looks at the first laws, which were introduced to improve road safety. Virtually every member of society is somewhat affected by road transport. All traffic participants are at risk of an accident to a certain degree which is why reducing this risk should become a priority.

Published: May 2018

Abstract
Introduction. The results of epidemiological and socio-medical studies of specific age groups in Poland indicate that tooth decay and periodontal diseases still pose a significant health problem.
Aim. The aim of the study was the assessment of the reasons for reporting to the dental office and the assessment of oral health in children aged 0-6 years.
Material and methods. The study comprised 45 patients in the preschool age (2-6 years old), who for the first time reported in 2015 to the dental office, which offers treatment under the framework of an agreement with the National Health Fund or for a fee. Gender, age, the place of residence and the reason for the reporting to the dentist were analyzed. The place of residence was a village, a town of less than 200 thousand inhabitants or the city of more than 200 thousand inhabitants. The reason for reporting to the dental office was a check-up visit, toothache or loss of filling. Dental condition was assessed by calculating the dmf index. The results were statistically analyzed.
Results. Among the surveyed, there were no children younger than 2-year-olds. It was found that the dmf index was ranging in an individual patient from 0 to 20, in half of them the dmf index value was ≤ 7, while in all of the patients the average dmf index was 6.42. The percentage of respondents with dmf=0 was significantly higher among children living in the city than children living in rural areas.
Conclusion. It is necessary to intensify educational activities concerning oral health of children, addressed to pregnant women, parents and people from the living environmental of a little child. This applies in particular to promoting early reporting to the first ever, the adaptive visit of a child to the dentist, frequent and regular check-up visits, during which, regardless of the examination, prophylaxis or treatment activities can be carried out if necessary.
