A Study on Environment - Oriented Knowledge, Attitude and Behavior Level of Teacher Candidates
The purpose of education should be to raise people who are researchers, developer, investigating what they find, use their knowledge in their behaviors and who can interpret and put new things on them. When children are being educated, the experience should be before the occurrence of the story. First, good and bad environment should be shown, then education should be provided through narration. In environmental education, young people should be given the chance to work in the organization. The goal should be to educate environmental literate individuals. The purpose of this study is to determine the social literacy and environmental literacy levels of the elementary school teacher candidates and to demonstrate the influence of various variables on the constituents of environmental literacy. The data show that candidate teachers' environmental behavioral tendencies are higher than environmental perceptual tendencies. Gender has no influence on behavior or thought. Keywords: environmental literacy, environmental problems, environmental education, candidate teachers, affective tendency towards the environment, environmental behavior
Fracture of an osteochondroma treated successfully with total excision: two case reports
Fracture of an osteochondroma is a rare complication. We report two cases of fractured osteochondroma in two children that were treated successfully with total excision
Open reduction and percutaneous pinning for medial condyle fractures of elbow in children: is it a risk for complications?
Background: There are limited cases of humerus medial condyle fracture in the literature treated by open reduction and percutaneous pinning. This study presents cases treated by open reduction and percutaneous pinning and discussed the problems reported in the literature.Methods: Nine cases were treated by open reduction and percutaneous pinning between 2006-2014. These cases were followed for nonunion, avascular necrosis, range of motion, nerve lesion and infection for 15.3 months (range 11 to 18 months).Results: No non-union, avascular necrosis, iatrogenic nerve lesion or infection developed in our cases. All patients gained full range of motion.Conclusions: This study presents that surgical technique and early timing of surgery prevents the complications
Streamflow forecasting using a hybrid LSTM-PSO approach: the case of Seyhan Basin
The conditions which affect the sustainability of water cause a number of serious environmental and hydrological problems. Effective and correct management of water resources constitutes an effective and important issue among scales. In this sense, a precise estimation of streamflow time series in rivers is one of the most important issues in optimal management of surface water resources. Therefore, a hybrid method combining particle swarm algorithm (PSO) and long short-term memory networks (LSTM) are proposed to predict flow with data obtained from different flow measurement stations. In this respect, the data gathered from three Flow Measurement Stations (FMS) from Zamanti and Eglence rivers located on Seyhan Basin are utilized. Besides, the proposed LSTM-PSO method is compared to an adaptive neuro-fuzzy inference system (ANFIS) and the LSTM benchmark model to demonstrate the performance achievement of proposed method. The prediction performances of the developed hybrid model and the others are tested on the determined stations. The forecasting performances of the models are determined with RMSE, MAE, MAPE, SD, and R-2 metrics. The comparison results indicated that the LSTM-PSO method provides highest results with values of R-2 (approximate to 0.9433), R-2 (approximate
Necrotizing leukocytoclastic vasculitis mimicking necrotizing fasciitis: a case report
There are several subtypes of necrotizing leukocytoclastic vasculitis, which are classified according to their morphological features in biopsy specimens using immunofluorescence microscopy. Necrotizing leukocytoclastic vasculitis is limited to the skin, predominantly that of the lower extremities, and usually spares the palms and soles. The most common skin manifestation is palpable purpura. Other skin manifestations include maculopapular rash, bullae, papules, nodules, ulcers and livedo reticularis. There is no specific laboratory test to determine the diagnosis. There are various diseases presenting with these nonspecific symptoms, and a rapid differential diagnosis must be conducted, because the appropriate differentiation and diagnosis markedly influence the treatment strategy and survival of patients. In this study, we report a case of necrotizing leukocytoclastic vasculitis presenting with internal organ involvement and symptoms of necrotizing fasciitis, with emphasis on the clinical differentiation
A biomechanical comparison of two cephalomedullary nails; one using a single lag screw with antirotator blade and a nail using two lag screws for unstable intertrochanteric fractures
Background: Implant choice for fixation of intertrochanteric fractures remains controversial despite being one of the most commonly performed operations. Although use of sliding hip screws is still considered a gold standard in treatment of these fractures, there is a wide tendency in using cephalomedullary nails because of their biomechanical superiority over sliding hip screws. This trial was initiated in order to compare the biomechanical properties of two different cephalomedullary nails, aPFN and the PROFIN under axial loading, based on the questions that can a single lag screw with an antirotator blade render better rotational stability? Is there a difference between one lag screw or two lag screws with respect to superior migration or cut-out of the screws? And do different nail designs cause different types of failure and what are the pros and cons of classical and new designs from the view point of biomechanical aspects?Methods: Ten pairs of third generation synthetic bone models simulating unstable intertrochanteric fracture were used for biomechanical testing.Results: No posterior displacement of screws was recorded in both groups suggesting rotational unstability. There was not a significant difference between forces values loaded at the time of failure.Conclusions: Although there was no statistically significant difference between compressive strengths at the time of failure, aPFN may provide equal rigid fixation with less possible cut-out which may have an important consequences in real clinical applications
Biochemical Analysis of Pentraxin 3 and Fibrinogen Levels in Experimental Periodontitis Model
Impact of neuraminidase inhibitors on influenza A(H1N1)pdm09‐related pneumonia: an individual participant data meta‐analysis
BACKGROUND: The impact of neuraminidase inhibitors (NAIs) on influenza‐related pneumonia (IRP) is not established. Our objective was to investigate the association between NAI treatment and IRP incidence and outcomes in patients hospitalised with A(H1N1)pdm09 virus infection.
METHODS: A worldwide meta‐analysis of individual participant data from 20 634 hospitalised patients with laboratory‐confirmed A(H1N1)pdm09 (n = 20 021) or clinically diagnosed (n = 613) ‘pandemic influenza’. The primary outcome was radiologically confirmed IRP. Odds ratios (OR) were estimated using generalised linear mixed modelling, adjusting for NAI treatment propensity, antibiotics and corticosteroids.
RESULTS: Of 20 634 included participants, 5978 (29·0%) had IRP; conversely, 3349 (16·2%) had confirmed the absence of radiographic pneumonia (the comparator). Early NAI treatment (within 2 days of symptom onset) versus no NAI was not significantly associated with IRP [adj. OR 0·83 (95% CI 0·64–1·06; P = 0·136)]. Among the 5978 patients with IRP, early NAI treatment versus none did not impact on mortality [adj. OR = 0·72 (0·44–1·17; P = 0·180)] or likelihood of requiring ventilatory support [adj. OR = 1·17 (0·71–1·92; P = 0·537)], but early treatment versus later significantly reduced mortality [adj. OR = 0·70 (0·55–0·88; P = 0·003)] and likelihood of requiring ventilatory support [adj. OR = 0·68 (0·54–0·85; P = 0·001)].
CONCLUSIONS: Early NAI treatment of patients hospitalised with A(H1N1)pdm09 virus infection versus no treatment did not reduce the likelihood of IRP. However, in patients who developed IRP, early NAI treatment versus later reduced the likelihood of mortality and needing ventilatory support
