Opis:
The paper presents a synthetic characterization of modern methods of manufacturing or regenerating machine elements. Considered methods are machining and additive methods, in particular 3D printing in the FDM/FFF technique. For the study, the authors made samples of the holder bracket using selected methods. Samples made by machining operations, 3D printing with various filling were tested. The paper contains a technical and economic analysis of the production of a holder bracket using the discussed methods. The dynamics of steel and FDM/FFF printed samples were also assessed by determining their resonance curves. The vibration magnification fac-tors were analyzed - the quotient of the vibration amplitudes in the resonance to the static deformations that occurred under the influence of the constant force and the location of the vibration resonances - the natural frequencies for individual vibration modes. The study's main objective is to assess the possibility of emergency changing the manufacturing technology of selected machine components. The authors were interested in partially replacing costly and not environmentally friendly milling with 3D printing. Machine elements can be manufactured by printing in classical machine building and emergency conditions to replace a damaged component temporarily (e.g., on a ship, for the time of arrival at a port or shipyard). The main assumption guiding the authors during the preparation of this publication was the analysis of the possibility of using the production of "ad hoc" prepared spare parts and their use in the event of a lack of access to parts made of the intended materials.

Opis:
Introduction: The patients with the aortic abdominal aneurysym of 55 mm in diameter are qualified to surgery. There are open repair (OR) by means of the vascular prosthesis implantation or the less invassive endovascular method by means of the stentgraft implantation through femoral arteries incision (EndovascularAorticRepair – EVAR). Aim: The aim of the study was the evaluation of the postoperative course in patients operated due to aortic abdominal aneurysm and the evaluation of the impact of the surgical method on the short-time results. Material and methods: 124 patients operated due to abdominal aortic aneurysm in Dept of Surgery of 4th Military Hospital in Wroclaw in 2014 were enrolled into the study: 53 patients with OR, 53 patients with EVAR, and 19 patients with ruptured aneurysm. Results: Mortality was 0% in EVAR and 6% in OR and 39% in ruptured aneurysm. Time of hospital stay was 5.8 days in EVAR vs 10 days in OR. The stay in ICU was 0% in EVAR vs 13% in OR. Blood transfusion was 9.4% in EVAR vs 66% in OR. Time of postoperative analgesia was 27 h in EVAR vs 76.8 h in OR. Cardio-respiratory decompensation was 1.9% in EVAR vs 7.6% in OR. Renal insufficiency was 2% in EVAR vs 9% in OR. The lower rate of organ complications was in EVAR. The ruptured aneurysm presented the most complicated postoperative course: hospital stay of 11.4 days, ICU stay of 78%, blood transfusion of 100%, painkillers of 136 hours, cardio-respiratory decompensation of 81% and renal insufficiency of 69%. Conclusions: The method of treatment, the conditions of the admision and the type of surgery influenced the postoperative course. The elective EVAR patients presented both the 0% of mortality and the lightest postoperative course. The ruptured abdominal aortic aneurysms operated as an emergency had the most complicated postoperative course.

Opis:
The article contains the analysis of factors influencing the efficiency of work of equipment maintenance, repair and operation (MRO) units of industrial enterprises. We have systematized various classifications of these factors, which were proposed in economic literature by different authors. We have divided the factors into following groups: general and local; primary and secondary; external and internal; major and non-essential; direct and oblique; reducing and boosting the expenses on equipment MRO and repair cost; production and non-production; depending on management and independent; economic, operation, organization ones; structural and production-technical ones; which are interconnected. It has been proposed to classify factors influencing the efficiency of equipment MRO units into five groups: economic, exploitation, organization, production-technical and structural ones. Using expert evaluation method, the factors have been divided into three groups according to degree of their influence on efficiency of work of equipment MRO units of industrial enterprises. The priority was given to the factors of the first group, having decisive influence on formation of efficiency. The most significant factors have been identified. In opinion of experts, these factors include: method of organization of work of equipment MRO service; level of economic autonomy of MRO enterprise in terms of organization of equipment MRO; financial and market situation of enterprise; the degree of repair complexity of production equipment.
