Introduction: A number of people with facial injuries after surgical treatment one knee time comes and a violation of the opposite knee. These injuries have a major impact on quality of life if they are not treated properly, but also have consequences and after surgery. The aim of this paper is to analyze the questionnaires used to assess the quality of life after mutual ruptured anterior cruciate ligament, and to make recommendations for optimal use of the same. Our goal is to establish a correlation between the results obtained from questionnaires used descriptive answers to questions descriptive questions about aspects of everyday life, aspects of physical activity as well as aspects of personal perception of the current health and satisfaction with it. Methods: We analyzed questionnaires used to evaluate the quality of life after a bilateral rupture of the anterior cruciate ligament, which are listed in the attached work. In accordance with the subject of research, in this paper were used the following scientific research methods: a method of deduction, analysis, classification, comparison, analysis methods of written documents. Results: By searching the PubMed database for the purpose of this master's thesis under the terms "unilateral rupture ACL" we came across a 2792 articles, while the term "bilateral rupture of the ACL," retrieved only 73 articles, "contralateral ACL rupture" 192 articles, "Quality of life ACL "  41 articles. The most important dates in our study are certainly "Quality of life after bilateral rupture of the anterior cruciate ligament," where we all find only two articles on this topic. Conclusion: The most commonly used questionnaires to be used in assessing the success of treatment and quality of life after a bilateral rupture of the anterior cruciate ligament are: QOL, IKDC, KOOS, HSS, ADL, SF-36, WOMAC. IKDC proved to be most suitable for patients with ACL rupture in this study.

Providing reliable and efficient operation of electronic devices often requires introducing of an additional protection from electric circuit parasitic components during the design stage. The paper analyzes the influence of a parasitic inductance on overvoltage at switching elements, which is an unavoidable part of the most electronic converters. The paper also describes the basic methods for avoiding this phenomenon. One example of an overvoltage protection of IGBT transistors based on TD350 control circuit is presented for a specific converter.

The paper conducts a survey of satisfaction level of users of two lane road in regards to constructional-geometrical factors influencing unimpeded traffic and influence of human element during its maintenance. Establishing the satisfaction level of users of existing road network is the primary goal of the paper, through the definition of Level of Service of relevance for the analysis of traffic of interurban road network. The survey was conducted on the road section Koprivna – Modrica, regional road R-465 (Busletic - Modrica). Using a questionnaire, the values of influence to the level of users’ satisfaction were established. Traffic infrastructure and elements of horizontal road signs have been identified as two main indicators giving negative grade to the level of satisfaction. The end of paper gives a review of measures for the improvement of existing conditions.

Introducao: O Diabetes Melittus (DM) e uma doenca sistemica metabolica cronica de prevalencia alta na populacao idosa, que pode implicar no agravamento de manifestacoes orais prejudiciais ao paciente. O cirurgiao-dentista tem papel importante no diagnostico e no tratamento dessas manifestacoes, bem como, pode auxiliar no controle do DM. Objetivo: Analisar, por meio de uma revisao da literatura sistematica, a relacao das condicoes de saude bucal com o DM. Metodos: Foi realizado um levantamento bibliografico nas bases de dados PubMed, LILACS e Scielo, buscando recuperar artigos relacionados ao tema, selecionados entre o periodo de 2005 e 2015. Conclusao: DM e saude bucal possuem uma relacao bidirecional, comprovada pela maior resistencia a insulina na presenca de inflamacao local e pela prevalencia de doenca periodontal e alteracoes em mucosa oral e glândulas salivares no paciente com DM descompensado. Alteracoes no meio bucal dos portadores de tal patologia tambem podem afetar sua funcao mastigatoria, e por conseguinte, a nutricao, impactando negativamente no controle glicemico. Portanto, o atendimento odontologico pode contribuir com a melhoria da condicao de saude bucal e sistemica alem da qualidade de vida dos idosos com DM.

In this paper two parameter Same Slope Seasonality forecasting model was developed. Analytical expressions for determining optimal parameter values of the developed two parameter Same Slope Seasonality forecasting model were developed too. Furthermore, performance of Two Parameter Same Slope Seasonality model was compared with performance of Holt-Winters exponential model as well as with performance of Same Slope Seasonality model. All tests were performed on M2-Competition time series. To determine the parameters of Holt-Winters exponential model, nonlinear mathematical programming was used. Performed tests proved that Two Parameter Same Slope Seasonality model is more successful than Holt-Winters exponential model and Same Slope Seasonality model. Expressions developed for determination parameters of two parameter Same Slope Seasonality forecasting model give parameter values identical to the values obtained by using Solver in MS Excel, set to solve nonlinear programming model, in a way that the problem is set up to search the parameter values which minimizes the mean squared error of the model.

Inventory systems that use continuous review policy are under risk during lead time, when stock-out can occur. Therefore, system must have enough on-hand units to prevent such situations. Generally, in inventory control literature it can be found that lead time demand follows normal distribution and all other conclusions are derived from this assumption. However, in real life this does not have to be true, so it is of crucial importance to get better estimates of stochastic demand parameters over lead time. The objective of this research is to estimate the optimal (s, Q) continuous review inventory policy parameters that reduce risk of stock-out during lead time and to enhance robustness of such estimated parameters. This is done using approach we propose for demand modeling. Performances and adequacy of the proposed approach for lead time demand modeling, with various demand patterns, and its application in (s, Q) continuous inventory models are obtained by simulation and show very good results.

Pneumatic conveying involves the transportation powder, granular and piece of material and is based on the phenomenon that at the appropriate speed of air in the pipeline, the solid particles are brought in the desired direction. If inlet air velocity is too high the material flow rate may be reduced, the power requirements will be excessive, and operating problems will be severe. Considering the advantages that air-slide conveyors can offer in relation to pneumatic conveying systems especially in terms of low power consumption and operating problems associated with abrasive particles, such as erosive wear of system components and degradation of friable particles. In this paper is presented design calculation of airslide conveyor in the thermal power plant.
