Opis:
When we assume that a survey reveals respondents’ true attitudes we tacitly assume that the subjects understood what we are asking them about and that they had no incentive to be untruthful. In typical studies none of the two assumptions holds. Subjects are asked questions that use undefined terms and they are asked about issues they have no incentive to answer truthfully. Here we argue that a way to solve the two problems lies in constructing a formal theory of an attitude in such a way that an attitude can be derived from the answers yet when answering the questions subjects cannot possibly know that their responses reveal anything about their attitude and, hence, they have no incentive to answer insincerely.We briefly discuss a study that has the desirable properties necessary for the proper design.

Opis:
In clinical practice, pain management following various surgical interventions is far from perfect. Despite advances in pharmacology, suffering of patients after surgery is still commonplace. A change in simple rules for managing postoperative pain, as well as introduction of standards for therapy would let change status quo. Introduction of multidrug therapy brings hope to improve patients’ comfort and efficacy of treatment.

Introduction: Neuroma (Schwannoma in Latin) is an encapsulated, mesenchymal tumor arising from Schwann cells surrounded by nerves. Hence it can be located in any area in the body with passing peripheral nerves. The most common location is the head, neck, and extremities. The tumor arising from Schwannoma cells was first described by Stout and Carson in 1935. Pancreatic schwannomas are extremely rare tumors. Until 2017, in English literature 68 cases have been described. Surgical treatment is the most common way of treating pancreatic schwannomas, and postoperative prognoses are good. Case report: A 63-year-old patient was admitted to the Clinical Department of Gastroenterological Surgery and Transplantation of the Central Clinical Hospital at the Ministry of Interior and Administration in Warsaw due to pancreatic head cancer. Needle biopsy–both ultrasound-guided and CT-guided as well as open biopsy for lesions in the pancreas did not show tumor cells in any of the collected samples. Abdominal CT in a projection of the uncinate process of the pancreas revealed an oval lesion highly suspected of neoplastic process. Next, diagnostics was extended by abdominal MRI which revealed a retroperitoneal tumorous thick-walled cystic mass filled with fluid. The patient was qualified for surgical treatment. Pancreaticoduodenectomy (Whipple Procedure) was done on August 22, 2017. Material sent for histopathological examination revealed Schwannoma capitis pancreatis. In surgical practice, pancreatic schwannoma occurs extremely rare, but in centers which conduct large numbers of surgical procedures in the pancreas, a case like this may occur.

Opis:
Purpose: The aim of the publication is to diagnose the level and to assess the possibility of using managerial dashboards created in an Excel spreadsheet to supervise management processes in enterprises. Design/methodology/approach: The research developed the method of a directed interview with the staff at various management levels. The supervision of technological processes, economic analysis, and the provision of broadly understood services for citizens have been the subject of the research. Findings: Managers show little interest in improving their employees' analytical skills. Training in this area is not planned and the impact of analytical capabilities of the tools available for the functioning of the company are not appreciated. Research limitations/implications: The results of the research are not representative, but they encourage the authors to carry out a broader and more in-depth analysis of the existing situation in enterprises. Practical implications: The research shows the need to rationalize human resources management. This process requires an increased supervision over employee development planning with the use of the appropriate training. This may have a significant impact on efficient management and, consequently, on the company's financial results. Originality/value: The article is to be an element stimulating the management to more thoughtful activities in the field of selection, training, and use of personnel at various levels of management in the company.

Opis:
The article presents the experimental strength evaluation of modular car trailers with a maximum permissible total mass of up to 3500 kg and its application to assess the mechanical strength of box-type car trailers. Tests were carried out using an original test bench dedicated to fatigue testing. They aimed to compare a trailer made in traditional technology with a trailer equipped with a load-carrying structure containing a sandwich panel. As a result of the conducted work, the displacement values of the measurement points were measured. The deformation form of the trailer made in the traditional technology was compared with the trailer containing the sandwich panel. The proposed method of experimental strength evaluation of modular car trailers enables a quantitative assessment of the mechanical strength of the load-carrying structures of trailers. This results in improved safety of trailer operation in road traffic by identifying the critical elements of the load-carrying structure at the early design phase before the trailer is allowed to run on the road.

Opis:
Introduction. According to the International Labour Organisation (ILO), agriculture is one of the most dangerous industries. The rate of fatal accidents in agriculture is about twice the average for other sectors. Aim. The aim of this study was to evaluate the level of knowledge of first aid concerning the most common injuries that occur in agricultural work. The analysis of the types of injuries during work in agriculture and their incidence among Polish farmers in the years 2013–2014 made it possible to define the most common types of injuries and their causes for the selected professional group and to draw up a survey for the farmers in order to achieve the main research goal. Material and methods. The study was conducted in two stages. At first, data from KRUS – Kasa Rolniczego Ubezpieczenia Społecznego (the Polish Agricultural Social Insurance Fund) was analyzed with reference to the incidence and the type of injuries that occurred in agriculture in 2013 and 2014. Then research was carried out by means of a survey based on the data obtained in the first stage. The study was preliminary and it was carried out on a sample of 51 persons. Results. The most common cause of the 41,702 incidents qualified by the Agricultural Social Insurance Fund as an accident in agriculture in Poland in the years 2013 and 2014 was a fall from heights. Every fourth respondent had witnessed or had been directly involved in an accident in agriculture. Despite the fact that everyone declared familiarity with the principles of first aid, over a half of the respondents had never given it. Conclusion. All of the respondents declared having knowledge of the principles of first aid, however, research shows that their knowledge is incomplete and not consolidated. Due to the fact that there are few reports on the research topic, it seems advisable to continue it in a larger study group. With reference to pesticide use, despite having knowledge of the hazard of intoxication by organophosphate compounds, a majority of farmers included in the study did not use any personal protective equipment.

Opis:
The authors discuss the material collected in the Suwalski Landscape Park in the years 2009 and 2011-2013, almost exclusively obtained from standing waters. At 29 study sites, 1 204 individuals representing 109 species from 12 families were caught, of which 55 species have been recorded for the first time in the examined area. The most valuable were: Gyrinus distinctus, Haliplus fulvicollis, H. variegatus, Ilybius erichsoni, Graphoderus austriacus, Hydroporus glabriusculus, H. incognitus, Hydrochus ignicollis, H. megaphallus, Spercheus emarginatus, Anacaena globulus, Berosus frontifoveatus, Enochrus melanocephalus, Hydrophilus aterrimus, Cercyon quisquilius, C. unipunctatus, Limnebius aluta, Dryops anglicanus, Heterocerus fenestratus and Cyphon pubescens. The most species were found in small water bodies and lakes. The collected material was ecologically diversified; dominating groups were eurytopes as well as tyrphobionts and tyrphophiles, rheophilous species were also numerous. Taking into consideration data discussed in this paper and literature as well as the lack of complex studies, in waters of the Suwalski Landscape Park 139 beetle species have been recorded so far, of which 136 species represent true aquatic beetles (the authors provide the list of them). This number is similar or even higher than the one recorded in well studied, the most valuable and diversified habitats in protected areas of Poland. The Suwalski Landscape Park is also the place of occurrence of many species under protection, from the Red List of Animals in Poland or regarded as rarely occurring in Poland. It is also a refuge of many seriously threatened species in neighbouring countries. This confirms a great, overregional role of this area in the protection of aquatic beetles and their habitats.

Parastomal hernias continue to be a significant clinical problem. Use of a synthetic material results in the best results of treatment of this pathology. However, treatment results are still unsatisfactory. The aim of the study is to present 6 cases of late complications of treatment of parastomal hernia using synthetic material, with successful surgical treatment. Material and methods. Among 52 surgical procedures of parastomal hernia repair using a synthetic material, 6 patients underwent late reoperation, including 4 women. Six reoperations were performed due to complications of parastomal hernia repair. Results. All cases of reoperation are presented and discussed in the study in order in which parastomal hernia repair procedures were performed. Conclusions. Presentation of 6 cases of patients treated for complications of the parastomal hernia repair procedure indicates that surgical technique of repair of this pathology is far from being perfect, although there has been a significant progress in this area over the past 20 years.

Opis:
Despite of nearly 100 years of turbine engine development and design, blade vibrations remain a great engineering challenge. The rotating turbine blades’ vibrations lead to cyclic oscillations, which result in alternating stress and strain in harsh environments of high temperature and pressure. In modern aeroengines, high hot flow velocities might generate erosion and corrosion pitting on the metal surfaces, that leverage remarkably mean stresses. The combination of both mean and alternating stresses can lead to unexpected engine failures, especially under resonance conditions. Then, alternating stress amplitudes can exceed the safety endurance limit, what accelerates the high cyclic fatigue leading quickly to catastrophic failure of the blade. Concerning the existing state-of-the-art and new market demands, this paper revises forced vibrations with respect to excitation mechanisms related to three design levels: (i) a component like the blade design, (ii) turbine stage design consisting of vanes and blades and (iii) a system design of a combustor and turbine. This work reviews the best practices for preventing the crotating turbine and compressor blades from High Cyclic Fatigue in the design process. Finally, an engine commissioning is briefly weighed up all the pros and cons to the experimental validations and needed measuring equipment.

Opis:
Palynological analysis of the 1st mid-Polish lignite seam (MPLS-1) of the Drzewce deposit (Konin region, central Poland) was used as the data source for palaeoenvironmental and palaeoclimatic interpretations. Lignites of the 1st group developed in the middle Miocene, during and shortly after the last peak of the Mid-Miocene Climatic Optimum, over a large area of Poland, and they are the youngest of the main Neogene lignite seams in Poland. In the Konin region, these lignites have a relatively significant thickness (up to 20 m) and therefore they are (or were in the past) exploited in several open-pit mines. A total of 36 palynological samples from the 6.3-m-thick seam of the Drzewce opencast mine was studied in detail. Palynological analysis of the lignite seam indicates that the area was overgrown by palustrine wetland communities, similar in composition to modern pocosins. The most characteristic elements of them were shrubs in the Ericaceae family. The climate at that time was warm temperate and humid. The estimated mean annual temperature (MAT) for the lignite seam at Drzewce is 15.7–17.8 °C. Comparison with other palynofloras from the MPLS-1 shows that the climate during the formation of the group of seams was more or less homogenous across the entire Polish Lowlands. Sedimentological data and results of palynological studies (including NPPs) at Drzewce indicate that the palaeomires were relatively distant from the channels of the river system in the Konin Basin. The fossil fungal assemblage indicates dense vegetation on damp, swampy soils and the presence of small, shallow-water bodies, with a variable water level or even periodic reservoirs, existing only during the wet season or after floods. In small, flooded depressions, such as the pools in bogs, filamentous green algae occurred. The presence of zygospores of the desmids Desmidiaceaesporites cosmarioformis most probably indicates relatively nutrient-poor (ombrotrophic) conditions. Fluctuations in the frequency of individual plant taxa (including Sequoia and Sciadopitys) are likely to reflect changes in water level and trophic conditions.
