Indicators of hospital treatment and the organization and management of injuries and diseases in armed combat in 1991 and 1992

Efficiency of organisation of management of the injured and diseased in combat operations in 1991/2 and results of hospital treatment are studied. The questionnaire was established for collection of data about stationary treatment of the wounded and diseased in 7 military and 15 civilian medical institutions. Data about 9.243 injured of whom only 5.57% were civilians are especially analysed. In most cases injuries were inflicted by mine-explosive devices (48.77% in combat and 6.27% in non-combat operations), then those inflicted by bullets (38.58% in combat and 8.02% in non-combat operations). Self-inflicted injuries occurred in 5.79% in combat and 10.32% in non-combat operations. Injuries inflicted in non-combat operations were found in a high percentage (46.60). They mostly occurred in the open air (41.26%). Injuries of extremities are predominant (64.70%), then injuries of the head and neck (17.90%), thorax (9.90%), abdomen and pelvis (7.50%). Young men (20-24 years old) were commonly injured but the older ones (over 40 years) have been also frequently injured (18.30%). Evacuation of the wounded and diseased was performed mainly by ambulances (about 60%) or helicopters (16%), especially to the medical institutions far in the country (to M.M.A. up to 60%). The first aid was given within the first ten minutes after injury in 55.00% and within 30 minutes in 65.58% of cases. Mutual aid was most frequently applied (33.12%) and then first aid given by general practitioners (32.12%). Surgical treatment was provided one hour after injury to every fourth wounded (24.08%) and after six hours to more than one third of the wounded (31.88%).(ABSTRACT TRUNCATED AT 250 WORDS)     

The microsurgical treatment of large and giant aneurysms of the internal carotid artery located parasphenoidally

Internal carotid aneurysms in the ophthalmic area presents a challenge in cerebrovascular neurosurgery. The study was undertaken to provide evidence for the application of intravascular aspiration during direct surgical interventions and to outline their variants used at the N. N. Burdenko Institute of Neurosurgery. The study included 4 (3 females and 1 male) patients with large and giant internal carotid aneurysms of parasphenoidal site who were treated at the Institute. Clipping of the aneurysmal neck was made by employing intravascular blood aspiration from the aneurysm. The technique proved to be effective in proximal monitoring the carotid artery at surgery. It substantially reduced aneurysmal blood flow and wall tension, thus favouring aneurysmal dissection to make clipping.     

Using the analytic network process (ANP) in a SWOT analysis - A case study for a textile firm

Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis does not provide an analytical means to determine the importance of the identified factors or the ability to assess decision alternatives according to these factors. Although the analysis successfully pinpoints the factors, individual factors are usually described briefly and very generally. For this reason, SWOT analysis possesses deficiencies in the measurement and evaluation steps. Although the analytic hierarchy process (AHP) technique removes these deficiencies, it does not allow for measurement of the possible dependencies among the factors. The AHP method assumes that the factors presented in the hierarchical structure are independent; however, this assumption may be inappropriate in light of certain internal and external environmental effects. Therefore, it is necessary to employ a form of SWOT analysis that measures and takes into account the possible dependency among the factors. This paper demonstrates a process for quantitative SWOT analysis that can be performed even when there is dependence among strategic factors. The proposed algorithm uses the analytic network process (ANP), which allows measurement of the dependency among the strategic factors, as well as AHP, which is based on the independence between the factors. Dependency among the SWOT factors is observed to effect the strategic and sub-factor weights, as well as to change the strategy priorities.     

The simulation of spin glass model of neural networks by the Wang-Landau algorithm

In the present work, the Hopfield neural network model with infinite-range interactions was simulated by using the Wang-Landau algorithm. All simulations and measurements were done in the replica symmetric and broken regions of the model with discrete ?1 values of random variables. The physical quantities such as energy density, specific heat were evaluated at all temperatures. Our results are in good agreement with the replica symmetric mean field solutions.

Passivation and corrosion behaviours of cobalt and cobalt-chromium-molybdenum alloy

Passivation and corrosion behaviour of the cobalt and cobalt-base alloy Co30Cr6Mo was studied in a simulated physiological solution containing chloride and bicarbonate ions and with pH of 6.8. The oxido-reduction processes included solid state transformations occurring at the cobalt/electrolyte interface are interpreted using theories of surface electrochemistry. The dissolution of cobalt is significantly suppressed by alloying it with chromium and molybdenum, since the alloy exhibited “chromium like” passivity. The structural and protective properties of passive oxide films formed spontaneously at the open circuit potential or during the anodic polarization were studied using electrochemical impedance spectroscopy in the wide frequency range.     

Relaxed stability and performance conditions for Takagi-Sugeno fuzzy systems with knowledge on membership function overlap.

This correspondence presents a relaxation of some earlier linear matrix inequality (LMI) conditions, which allow setting up less conservative stability or performance conditions for Takagi-Sugeno fuzzy models. Unlike the previous literature, this correspondence takes into account the knowledge of the membership functions' shape by considering bounds on them and their cross products (interpreted as an overlap measure), introducing auxiliary LMI variables. Numerical examples illustrate the achieved improvements.
