Video in e-learning systems

The world is changing rapidly in the field of multimedia and it is inevitable to prepare to use and utilize the new teaching method. This is specifically true in the case of the use of educational films both as video and also using such video on the Internet. Our first task is to decide whether the development of material will be an independent film or a part of an e-learning course. In both cases the method of construction is different. The next step is to select the target group of the film. There is a wide scale of possible viewers or participants (who must have a certain level of basic knowledge) and also handicapped people should be able to use the results. The final product ought to be acceptable for e-learning and distance-learning as well. Using the information technology in education is general and the present being of the e-learnig is part of this fact. We can use e-learning effectively only if the system is filled up with electronic educational material. The most effective ones are the multimediamaterials. The effectiveness of the multimedia-material can be improved with the application of video

Landslide - analysis and stabilization

Several metres thick top cover of a hillside slid down in a town near to Budapest. Buildings, communication and utility lines suffered damage. The author has found the cause of the movement in the seeping ground-water on the top of the underlying highly plastic clay. The design of stabilization rested on underground investigations and finite element analysis. The actual event calls the attention what type of careful arrangements are needed at similar construction projects

MODELLING OF REINFORCED SOIL

Geosynthetics are being used increasingly to improve soil properties and to obtain better performance from soft or weak foundation sites. It is well-known that the overall stability is improved and that the movement of the structures founded on the reinforced soil reduces because of the mobilization of tensile forces in geosynthetics. This force is well quantified in the analysis of stability of structures constructed with reinforced soil. However, studies on modelling aspects are not many. In this paper, models are considered to quantify the effect of tensile force. Solutions for an embankment (strip) type of load are presented

Földrengés nyomai a kalotaszegi Magyargyerőmonostor református templomán: Evidence for earthquake damage in the Calvinist church of Mănăstireni (Magyargyerőmonostor, Romania)

Archaeoseismological study of the Medieval Calvinist church at Mănăstireni (Magyargyerőmonostor, Romania) revealed various deformation features which are attributed to earthquake(s). Tilted northern wall supported by buttresses, deformed, sunken arches, and masonry blocks bearing crosscutting fractures support dubious historical evidence that the southern tower collapsed due to an earthquake sometime in the 17-18th century

Planning of Optimal Fuel Supply of International Transport Activity

The selection of the petrol station for refuel and the amount of refilled fuel are not determined centrally at most transport companies, but depend on the individual decision of the driver, so that the total cost of the burned fuel is not minimal. The goal of this study is to elaborate a precise and reliable mathematical model and method for the determination of the optimal refuel points and the amount of loaded fuel to fulfil specific transport tasks. The model is a mixed valued non-linear programming model, which can be handled by optimization procedures. Based on the elaborated model and method, a decision-supporting software was developed, which provides the required information that is necessary for the economical fulfilment of transport trips

Thrombotic Thrombocytopenic Purpura, Moschcowitz Syndrome

The authors present a case of a 16-year-old boy, who was referred to the hospital due to thrombocytopenia, anemia, proteinuria and hyperbilirubinemia. Based on the clinical picture and the laboratory data, thrombotic thrombocytopenic purpura (TTP) was diagnosed. The adequate therapy was immediately started. TTP is quite a rare entity. The etiology and the pathogenesis are not well defined. The authors summarize the different pathomechanisms, which may play a role in the development of TTP. Similarity to the hemolytic uremic syndrome (HUS), therapeutic possibilities, prognosis and the outcome are also discussed. The importance of the early diagnosis of TTP in childhood, and life-saving effect of the adequate treatment are emphasized
