Wypalenie zawodowe wśród pracowników bloków operacyjnych

Introduction. The phenomenon of burnout is defined as a state of emotional, physical and spiritual exhaustion. Health care workers, belong to professions that are often the focus of attention of researchers dealing with these issues. Aim. The aim of the research was to assess the level of occupational burnout among employees of operating theatres. Material and methods. The study was performed on a group of 325 members of staff of operating theatres. The work involved the method of diagnostic survey and statistical methods. The questionnaire technique was used based on standardized research tools including Maslach Burnout Inventory (MBI) and Areas of Worklife Survey by Christina Maslach and Michael Leiter, and authors questionnaire. Results. A higher level of occupational burnout among staff of operating theatres was recorded in women, subjects with BA degree in nursing, surgical nurses, and in persons who did not have any additional work. Workload, the sense of justice and self-esteem are the areas of professional life which have a significant impact on the degree of the subjects’ burnout. The study demonstrated that areas of non-adjustment to the working environment are predictors of the subjects’ emotional exhaustion, depersonalisation and reduced sense of personal achievements of the respondents. Conclusions. The study demonstrated that occupational burnout can be found in all its dimensions among the staff of hospital operating theatres. The association with occupational burnout of the respondents has socio-demographic factors, absence of additional work and areas of professional life influence.
Conservation of biological resources

© 1998 by Blackwell Science Ltd. All rights reserved. This book presents the issues surrounding the conservation of wild species and ecosystems used by people. It is aimed at final year undergraduate and master's students taking courses in conservation, environmental management, ecological economics and related subjects, as well as conservation professionals, including managers, policy-makers and researchers. The structure of the book is ideal for a course in conservation, comprising a theoretical section written by the authors, and a set of ten contributed case studies intentionally diverse in discipline, geographical region and system of study. The theoretical section provides the knowledge that is needed to understand the issues, while the case studies can form the basis of seminars. Readers will emerge with a clear recognition of the difficulties of limiting the harvesting of biological resources to sustainable levels, and of the boundaries of sustainable use as a conservation tool. The authors, an ecologist and an anthropologist, have both worked on the conservation and sustainable use of wildlife for several years, including the ivory and rhino horn trades. The first book to examine the issues underlying the sustainable use debate in a fully interdisciplinary manner. Both the theoretical section and the case studies approach the issues using methods from economics, ecology, anthropology and other fields. Designed as a course textbook, combining a theoretical section with invited case studies written by expert practitioners in the field. Outlines the new direction that conservation biology (and thus conservation biologists) must take if it is to be successful.
RELEVANCE OF IS PROJECT SUCCESS DIMENSIONS – A CONTINGENCY APPROACH

Measurement of information system project success (ISPS) remains an unsolved challenge. Instead of seeking a commonly accepted measurement approach, some scholars suggest to assess ISPS by applying a contingency approach. Its central idea is that no set of success dimensions fits best in all situations; instead, the dimensions’ relevance differs depending on variables like stakeholder perspective or project characteristics. We continue existing research by investigating how the relevance of success dimensions varies depending on project characteristics like complexity or size. We conduct a quantitative survey among experienced project managers in Germany. Results from 102 projects indicate that whereas certain dimensions (e.g., meeting customer requirements, customer satisfaction) are important in most projects, the relevance of many dimensions significantly varies depending on project characteristics. For researchers, we expect the more adequate assessment of ISPS to increase the validity of ISPS studies. We help practitioners to identify relevant ISPS dimensions for their projects.
ImagePilot 2.0, A Drawing Interpretation Tool for the Sight-impaired

This thesis describes the design and implementation of an innovative drawing interpretation tool for the sight-impaired. The move towards Graphical User Interfaces in today's computer era presents many challenges to those with impaired vision. Although there are many tools to aid this group in reading and writing text-based electronic documents, few software packages are available to help the sight-impaired interpret electronic images. This new tool, known as ImagePilot 2.0, processes electronic image files that contain line drawings and produces audio feedback to guide the user through the drawing. ImagePilot 2.0 receives input through a pointing device, thereby providing the user with a means of examining a drawing interactively, and serving as an aid for recognizing the outlines of familiar shapes and objects. In this study, a " line drawing " is a simple image that contains line segments and curves, without any shading or colors. It can be represented as a 2-dimensional array of picture elements (pixels), in which each pixel is either black or white. The drawing is represented by a pattern of black (foreground) pixels against a white background. Typically, groups of connected foreground pixels represent segments or curves that are associated with a single object. ImagePilot 2.0 makes it possible for a sight-impaired user to interpret such an image. Line drawings can be stored in many different electronic formats. ImagePilot 2.0 supports valid Graphics Interchange Format (GIF) files. If the foreground image regions in the file are wider than one pixel in width, a Zhang-Suen thinning algorithm is applied to thin the drawing. The tool identifies the separate regions in the drawing and decides on the best starting point for each region. Once a starting point is chosen, the drawing is processed using a modified chain-coding algorithm. iii The audio feedback consists of two types of audio cues, verbal and tone, along with stereo playback. Verbal feedback guides the user with a set of verbal cues played through the speakers. The tone feedback uses three tones representing above, level, and below the horizontal. The left and right speakers provide left and right directional information at each level. Speed is a critical factor in image analysis and interpretation applications. While the tool is receiving and processing input, it must also respond to the user within an acceptable amount of time. ImagePilot 2.0 uses multi-threading and multi-tasking techniques to achieve higher performance speeds. After design and implementation, two groups …
Three Dimensional Analysis of Extrusion through Taper Die

An upper bound solution for extrusion of “triangular” sectioned product through taper die from round sectioned billet has been developed. A simple discontinuous kinematically admissible velocity field with optimization parameter is proposed. From the proposed velocity field the upper bound solution on non-dimensional extrusion pressure are determined with respect to chosen process parameters. The theoretical results are compared with experimental result to check the validity of the proposed velocity fields. The reformulated SERR technique is used to find out the kinematically admissible velocity field applied to deformation zone surrounded by flat surfaces. This velocity field is used to compute upper bound extrusion pressure at various area of reduction. The triangular sectioned product from round sectioned billet through taper die is taken for upper bound analysis using SERR technique. As this section is symmetry about one axis with round sectioned billet only one half of section is taken as domain interest for deformation zone to calculate the velocity field. Detailed formulations of models are presented. To validate the proposed model/analysis experiments are carried out taking lead as the working material. An experimental set-up is designed and fabricated with four split type taper dies for this purpose. Experiments are carried out at dry and lubricated condition of the dies to check the friction effect. The results obtained indicate that the predictions both in extrusion load and the deformed configuration are in good agreement with the experiment under different lubrication conditions.
Linking perceived value of mobile marketing with the experiential consumption of mobile phones

Purpose – This study examines the nature of consumers’ perceptions of the value they derive from the everyday experiential consumption of mobile phones and how mobile marketing (m-marketing) can potentially enhance these value perceptions. Methodology – Q methodology is used to examine how consumers’ subjective perceptions and opinions are shared at a collective level. Forty participants undertook two Q sorts and the data was analysed using PQ-method. Findings – The first Q sort identified three profiles of perceived value: the Mobile Pragmatists, the Mobile Connectors and the Mobile Revellers. The second Q sort identified two profiles of perceived value of m-marketing: one emerging from the shared opinions of the Mobile Pragmatists and the Mobile Connectors, and the second from the Mobile Revellers. Implications/limitations – The findings show how consumers can be segmented based on their contextualised perceived value of consuming mobile phones and how the potential for m-marketing is perceived in ways that can enhance these value perceptions. Limitations relate to deriving statements for the Q sorts and the generalisability of the results. Practical implications – The findings highlight ways to tailor m-marketing strategies to complement consumers’ perceptions of the value offered through their mobile phones. Originality/value of paper – The study contributes to the literature through using Q methodology to examine two subjective areas of consumer behaviour, experiential consumption and consumer perceived value. Keywords mobile phones, mobile phone marketing, consumer perceived value, Q methodology, experiential consumption Classification Research paper
TM Polarized Plane Wave Scattering by a Conducting Plate with Multiple Holes

The Kirchhoff approximation (KA) is utilized to analyze electromagnetic scattering of an electromagnetic plane wave by a plate with multiple holes. Scattering far-fields are obtained by the summation of the radiation integrals due to the equivalent magnetic currents on the virtually closed surface on holes and the exterior of the plate. The accuracy of our formulations has been compared with the numerical solution, and good agreement has been confirmed to validate our formulation.
Balancing wheeled robot

Inverted pendulum has long been the interest of control engineers. The concept of two wheeled balancing robot is based on the inverted pendulum theory. A suitable control system is needed to control the system so that it is balanced and stable. The main purpose of this project is to use a good control strategy to keep the body of the robot upright. This dissertation applies the idea of non-linear control strategy and analyses its effectiveness. The non-linear control strategy requires a good understanding of the inverted pendulum system. The knowledge is then implemented in programming to program the microcontroller. This is particularly important in low-level assembly language, which is used in this project.
A chirped, pulsed laser system and magneto-optical trap for rubidium

This thesis covers the construction and characterisation of a magneto-optical trap (MOT) for 85Rb from the very beginning. It details both the optical and mechanical aspects from laser diode assembly, tuning and stabilisation to the preparation and assembly of the vacuum system. The MOT construction forms the first goal of the project, the second was to develop a laser system capable of producing custom programmable, amplitude modulated and frequency chirped pulses (on the tens of microseconds timescale) from a continuous wavesource. This involved developing software and computer control for several arbitrary signal generators linked to drivers for acousto-optic and electro-optic modulators. This chirped, pulsed laser system will be used to perform state manipulations on the 85Rb MOT cloud using two-photon Raman transitions in an adiabatic rapid passage regime. The chirped pulse system was initially tested with a rubidium vapour cell in an attempt to perform atomic interferometry that would produce spatial interference fringes along the length of the cell. However, due to the beam power requirements, the beam diameter together with the large Doppler shift at room temperature meant these fringes were not seen and so the vapour cell was replaced with the cold atom cloud in the MOT. Two-photon experiments were attempted with the MOT cloud using the chirped pulse system, however despite greatly improved laser power and detection efficiency, the signal indicating ground state population transfer via a two-photon interaction was not seen. The results indicate that the hyperfine-ground state splitting frequency has been shifted due to the proximity of the ion pump magnet to the vacuum system. Presently, efforts are being directed towards searching for the correct frequency.
Reducing the Volume of Reflectarray Antennas Using Near-Field Feeding

We propose a method to miniaturize a reflectarray antenna (RA) using near-field feeding. In a conventional design way of RAs, a source feeder is in a far-field region to avoid ambiguity in incident polarization. However, the distant source makes the corresponding reflectarray large to prevent the incident energy from spillover. To solve the problem, we have proposed a new near-field feeding method, like the way that we put a normal dipole antenna over a ground plane. The expected polarization ambiguity problem was solved using the reciprocal behavior of passive antennas. Consequently, we were able to reduce the overall volume of RAs remarkably.
LOCAL SCOUR NEAR OFFSHORE PIPELINES

The present investigation of local scour treats model tests with scour from a uniform flow near pipelines resting on the bottom and pipelines more or less buried. Two different flumes with uniform flow perpendicular to the longitudinal axis of the pipes were used for the experiments. The following mean flow velocities were used: V equals 0.25 m/s, 0.35 m/s and 0.45 m/s. The mean diameter of the bed material was 74 microns. Thirty-two experiments including 4 diameters D = 6.0 cm, 11.0 cm, 22.5 cm and 50.0 cm were carried out. On the basis of these model experiments the following has been estimated for a uniform flow: 1. The development with time of the scouring processes. 2. The different scour patterns near the pipes when they are resting on the bottom and when they are more or less buried in the sand. 3. Possibilities with relevant parameters to extend the observed results for use on prototypes. If test facilities available the experience gained will be used in a further work investigating scour from waves and scour from a combination of currents and waves.
Performance analysis of interior permanent magnet synchronous motor (IPMSM) drive system using different speed controllers

The present research is indicating that the Permanent magnet motor drive could become serious competitor to the induction motor drive for servo application. Further, with the evolution of permanent magnet materials and control technology, the Permanent Magnet Synchronous Motor (PMSM) has become a pronounced choice for low and mid power applications such as computer peripheral equipments, robotics, adjustable speed drives and electric vehicles due to its special features like high power density, high torque/inertia ratio, high operating efficiency, variable speed operation, reliability, and low cost etc. Here we deals with the detailed modeling of an IPMSM drive system with Hybrid PI-Fuzzy logic controller (PI-FLC) as speed controller and Adaptive Hysteresis Current Controller as torque controller by controlling the current components of torque.In this thesis we deals with a simulation for speed control and improvement in the performance of a closed loop vector controlled IPMSM drive which employ two loops for better speed tracking and fast dynamic response during transient as well as steady state conditions by controlling the torque component of current. The outer loop employ Hybrid PIFuzzy logic controller (PI-FLC) while inner loop as Adaptive Hysteresis Band Current Controller (AHBCC) designed to reduce the torque ripple. Despite proportional plus Integral (PI) controller are usually preferred as speed controller due to its fixed gain (Kp) and Integral time constant (Ki), the performance of PI controller are affected by parameters variations, speed change and load disturbances in PMSM, due to which it results to unsatisfied operation under transient conditions. The drawbacks of PI controller are minimized using fuzzy logic controller (FLC). So for this a fuzzy control technique is also designed using mamdani type, triangular based 5x5 MFs and selecting the superior functionalities of PI and FLC, a Hybrid PI-FLC designed for effective speed control under transient and steady state condition.The complete viability of above mentioned integrated control strategy is implemented and tested in the MATLAB/Simulink environment and a performance comparison of proposed drive system with conventional PI, fuzzy logic controller and Hybrid PI-Fuzzy Logic Controller integrated separately as speed controller in terms of steady state and transient analysis with fixed step, variable step load and variable speed condition has been presented. Beside this a detailed comparative study of AHBCC is also done with Conventional Hysteresis Current Control(CHCC) scheme. The simulation circuits parameters for IPMSM, inverter, speed and current controllers of the drive system are given in Appendix-A.

Social Robot Navigation

Mobile robots that encounter people on a regular basis must react to them in some way. While traditional robot control algorithms treat all unexpected sensor readings as objects to be avoided, we argue that robots that operate around people should react socially to those people, following the same social conventions that people use around each other. This thesis presents our COMPANION framework: a Constraint-Optimizing Method for Person-Acceptable NavigatION. COMPANION is a generalized framework for representing social conventions as components of a constraint optimization problem, which is used for path planning and navigation. Social conventions, such as personal space and tending to the right, are described as mathematical cost functions that can be used by an optimal path planner. These social conventions are combined with more traditional constraints, such as minimizing distance, in a flexible way, so that additional constraints can be added easily. We present a set of constraints that specify the social task of traveling around people. We explore the implementation of this task first in simulation, where we demonstrate a robot's behavior in a wide variety of scenarios. We also detail how a robot's behavior can be changed by using different relative weights between the constraints or by using constraints representing different sociocultural conventions. We then explore the specific case of passing a person in a hallway, using the robot Grace. Through a user study, we show that people interpret the robot's behavior according to human social norms, and also that people ascribe different personalities to the robot depending on its level of social behavior. In addition, we present an extension of the COMPANION framework that is able to represent joint tasks between the robot and a person. We identify the constraints necessary to represent the task of having a robot escort a person while traveling side-by-side. In simulation, we show the capability of this representation to produce behaviors such as speeding up or slowing down to travel together around corners, as well as complex maneuvers to travel through narrow chokepoints and return to a side-by-side formation. Finally, we present a newly designed robot, Companion, that is intended as a platform for general social human-robot research. Companion is a holonomic robot, able to move sideways without turning first, which we believe is an important social capability. We detail the design and capabilities of this new platform. As a whole, this thesis demonstrates both a need for, and an implementation and evaluation of, robots that navigate around people according to social norms.
