Abstract

The intensive growth in the popularity of Remotely Piloted Aircraft Systems (RPAS) used for recreational, sporting and other purposes, may lead to an increase in accidents and incidents involving them. Therefore, it is advisable to raise the awareness of all users, related to safety issues, to harmonize standards and procedures applicable at international and national level. The article presents the legal conditions for unmanned operations and the risk assessment methods used in areas of human activity. On this basis, an original method of risk assessment in unmanned systems was proposed. The method can be part of the operating instructions of the RPAS operator. At the end, final conclusions were drawn up.

Abstract

The lower Indus basin is one of the prolific basins in Pakistan in which the C-interval of lower Goru formation act as a reservoir. With the help of petrophysical interpretation production zone is recognized and also porosity is calculated at the reservoir level. Through porosity we are able to calculate Ksat. A model based inversion of 2D seismic inversion was performed to ascertain three dimensional dispersion of acoustic impedance in the investigation zone and we have recognized new areas where porosity distribution is maximum and site which is suitable for new well. Porosity and Acoustic impedance are typically contrarily relative to each other. Presently porosity can be anticipated in seismic reservoir characterization by utilizing acoustic impedance from seismic inversion far from well position.

Abstract

Introduction. Professional image of the nurse in the opinion of the patient community is conditioned by many variables, including professional attire. A worthy representation of the nurse profession is the responsibility of all those who care for the patient.

Aim. Determining the impact of dress code on shaping the professional image of nurses in the opinion of patients.

Material and methods. Non-systematic review method of the literature available. The data was obtained by searching online databases, such as: Google Scholar, PubMed, CINAHL Complete as well as electronic resources of nursing magazines.

Results. In the perception of hospitalized patients, the nursing dress code affects the level of trust in those who care for patients, it also constitutes an important element in assessing their professionalism, knowledge or confidence when performing specific medical interventions. Adapted to the needs, a suitably selected style of professional attire of a nurse employed in a given health care facility enables her proper identification of them against the background of other members of the therapeutic team or administrative employees. In addition, the comfort of nurses is a significant factor for patients in dress code strategy planning; it often determines professionalism and quality of services provided.

Conclusions. There is a relationship between the external appearance of nurses and their professional image and the patients’ perception of their professional skills as well as the level of their professionalism. Dress code in a health care facility may constitute a significant element of image policy for both a health care facility itself and a group of nurses.

Abstract

Introduction: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease with undetermined etiology. Due to diverse symptomatology, it requires a thorough differential diagnosis, with consideration of conversion disorders. The presented thesis describes a case of a young man hospitalized in the Department of Psychiatry in order to verify the possible psychogenic basis of his symptoms, which previously were considered to be a manifestation of neurological disease with an unfavorable prognosis.

Aim: The aim of the thesis is to raise the issue of a multidisciplinary approach to diagnostic process in medicine, as well as taking into account the legitimacy of including psychiatrists, psychologists, and psychotherapists in diagnostic teams.

Case study: We present a case report of a man who has been experiencing progressive feeling and walking problems for the past several years, which originally suggested a neurological or rheumatological disease. Earlier observations and medical tests had led to a diagnosis of amyotrophic lateral sclerosis. After several years, the diagnosis was excluded, and the patient was referred to the Department of Psychiatry to determine the possible psychogenic basis of his symptoms. Diagnostic methods used during the patient’s hospitalization confirmed the conversational nature of his symptoms, and both pharmacological and psychotherapeutic treatment caused reduction of severity of his symptoms and allowed him for a gradual return to independent functioning.

Conclusion: Analysis of the collected data, including patient’s life history and a course of his treatment, indicates the validity of a holistic approach to medical problems, which implies the inclusion of specialists in the field of psychiatry, psychology, as well as psychotherapists in diagnostic teams. Such a multidimensional view of the patient and the source of his symptoms may allow for faster diagnosis and may also contribute to reducing the risk of making mistakes such as an incorrect assessment of factors triggering the disease process.

Abstract

Introduction. Working conditions often involve employees’ exposure to factors having adverse effects on their health. Due to its nature, the nursing profession entails numerous risks, associated both with harmful factors and a work system itself.

Aim. Aim of this study was to analyze the influence of a shift work system on self-reported health status and health behaviors of nurses.

Material and methods. The study included 200 nurses employed in three Szczecin hospitals: the Independent Public Clinical Hospital no. 1, Pomeranian Medical University in Szczecin, Independent Public Clinical Hospital no. 2, Pomeranian Medical University in Szczecin, and Independent Public Voivodeship Integrated Hospital. The research instruments were the Health Behavior Inventory (HBI) developed by Zygfryd Juczyński, and a self-developed questionnaire concerning sociodemographic and medical data.

Results. When it comes to 76% of the nurses, they described their health status as good or very good. The majority of the respondents (54%) displayed a low level of health behaviors. The most common work-related complaints were sleep disorders (55%), headaches after return home from work (55%), irritation after return home from work (83%), skin problems (28%), back pains (76%), leg pain/fatigue (84%), and eating disorders (14%).

Conclusions. 1. A work system had substantial effect on self-reported health status of the studied group of nurses. 2. The nurses working day shifts displayed a higher level of health behaviors than their counterparts working in a shift system. 3. A day/night shift work pattern correlated with a higher incidence of eating disorders.

Abstract

The Durmitor flysch complex represents a specific formation both in lithological and engineering geological sense. In the engineering geological sense this lithological formation is characterized by anisotropic and heterogeneous geotechnical properties, which depend on the dominant members within each individual package, as well as their spatial position.The Durmitor flysch complex consists of five superposition bed packages, which are mutually substantially different in their lithological, hydrogeological and geotechnical properties. For the first time in geological literature, this paper distinguishes five types of terrain construction within the Durmitor flysch complex. Contemporary geodynamic processes and their character within the flysch formation are defined. Particular emphasis is put on landslides, which represent a contemporary geodynamic phenomenon with certain specificities.

Abstract

Introduction. Folic acid is a compound classified as B group vitamins. In the body it is subject to processes that transfer its inactive form into a form responsible for biological effects of folic acid, i.e. 5-methyltetrahydrofolate (5-MTHF). It is, in particular, responsible for processes of the correct biosynthesis of purine and pyridine bases present in the formation of DNA and RNA molecules. Humans do not synthesize the endogenous form of folic acid; therefore, it is vital to supplement this vitamin in its natural form or multivitamin preparations. The most folic acid is found in the green leafy vegetables (spinach, peas, asparagus) and in offal (liver). An adequate supply of folic acid is especially indicated in pregnant women with a reduced amount of folic acid due to its use by an intensively developing foetus. The recommended dose of folic acid during this period is 0.4 mg/24h and this dose varies depending on the patient’s and her family’s medical history. The updated state of knowledge on the role of vitamin B9 in the body has been presented. The importance of its supplementation in specific clinical cases was analyzed.

Summary. Many studies indicate an important role of the folic acid in the prevention of congenital defects of the nervous, cardiovascular and urogenital systems. Its deficiency increases the risk of complications in pregnancy, such as recurrent miscarriages, pre-eclampsia or postpartum haemorrhage. For this reason, a prophylactic folic acid supplementation is recommended, in women with increased risk of its deficiency, in particular.

Abstract

The evaluation of team work schedules in complex rail transport conditions is related to the robustness of individual solutions. In rail systems there are many aims that are important for users. One of the most important aims is to find a feasible solution. It is characterized by the non-conflicting schedule with another train, minimizing the travel time of the trainset and taking into account the priority of train. The problem of responding to delays in terms of reorganisation of work, prevention of delay propagation and real-time schedule changes is important. Schedules are built in a way that ensures the best use of work time. This has a negative impact on critical situations. The study analysed the changes of the conductor’s team to another train depending on the buffer time provided in work plan, real time needed for change and train delays.

Abstract

Background: Over the past years, eosinophil infiltration involving the gastrointestinal tract and pancreas leading to eosinophilic pancreatitis, eosinophilic gastroenteritis and hypereosinophilic syndrome, has been reported in the literature.

We aimed to analyze and compare the features involving patients with eosinophilic pancreatitis and pancreatitis associated with eosinophilic gastroenteritis and to determine ifthere is a connection between the two disorders or if they in fact meet the diagnostic criteria for hypereosinophilic syndrome.

Material and methods: The following search was performed in March 2019 on PubMed (MEDLINE) database using the medical terms “pancreatitis”, “eosinophilic pancreatitis”, “eosinophilic gastroenteritis” and “hypereosinophilic syndrome”.

Results: The search revealed 119 publications from 1970 onwards. A total of 83 papers were excluded, and the remaining 36 publications, consisting in case reports and case series, were analyzed. From 45 patients, 20 subjects with eosinophilic gastroenteritis developed pancreatitis, 20/45 had eosinophilic pancreatitis, and 5/45 Hypereosinophilic syndrome involving the pancreas. There was no significant difference regarding clinical, laboratory and imaging features between the three groups, despite the multiple theories that explain the association of pancreatic and gastrointestinal eosinophilic infiltration. Although there was a strong resemblance between the three groups, histological evidence of eosinophilic gastrointestinal infiltration guided the treatment towards a less invasive way, while subjects with eosinophilic pancreatitis underwent pancreatic surgery to exclude potentially malignant lesions.

Conclusion: Although there are various theories that explain pancreatitis development in patients with eosinophilic gastroenteritis, hypereosinophilia diagnostic work-up should be taken into account in all patients with high number of blood eosinophils, even in those with eosinophilic pancreatitis in order to establish the diagnosis using a minimally invasive approach and to apply an adequate treatment.
