Variables Affecting Student Motivation Based on Academic Publications

In this study, the variables having impact on the student motivation have been analyzed based on the articles, conference papers, master's theses and doctoral dissertations published in the years 2000-2017. A total of 165 research papers were selected for the research material and the data were collected through qualitative research techniques through document review and content analysis. According to the research results, the most important factors affecting student motivation are the fields of teacher, teachers’ classroom management skills and their teaching methods. In this research, factors having less influence on the student motivation are parental communication, student characteristics and study fields. In addition, relational search type was used more than others, mostly students were selected as the study group and most researches were conducted in USA and Turkey. Keywords: Motivation, classroom management, teaching method, publications   

International symposium on peripheral nerve repair and regeneration and 2nd club Brunelli meeting

The International Symposium "Peripheral Nerve Repair and Regeneration and 2nd Club Brunelli Meeting" was held on December 4-5, 2009 in Turin, Italy (Organizers: Bruno Battiston, Stefano Geuna, Isabelle Perroteau, Pierluigi Tos). Interest in the study of peripheral nerve regeneration is very much alive because complete recovery of nerve function almost never occurs after nerve reconstruction and, often, the clinical outcome is rather poor. Therefore, there is a need for defining innovative strategies for improving the success of recovery after nerve lesion and repair and this meeting was intended to discuss, from a multidisciplinary point of view, some of today's most important issues in this scientific field, arising from both basic and clinical neurosciences

Monitoring cantilever beam with a vision-based algorithm and smartphone

The study presented in this manuscript deals with a non-contact structural health monitoring approach based on the use of smartphone and computer vision algorithm to estimate the vibrating characteristics of a cantilever slender beam. We hypothesize that the vibration of the beam can be captured using a smartphone in slow-motion modality and the natural frequency of the beam can be extracted using a computer vision algorithm. The results show an excellent agreement between the conventional contact method and the non-contact novel approach proposed here

Relationship between handedness and toothbrush-related cervical dental abrasion in left- and right-handed individuals

AbstractBackground/purposeCervical tooth abrasion is the loss of tooth material at the cementoenamel junction, and is usually related to faulty brushing habits. In this study, we attempted to evaluate the effects of handedness on tooth-brushing abrasion in terms of brushing habits in left- and right-handed adults.Materials and methodsIn total, 488 subjects participating in the study were divided into 2 groups according to hand preference (group I; left-handed and group II; right-handed), and were interviewed about their brushing habits, and their clinical oral conditions such as the plaque index (PI), gingival index (GI), and tooth wear index (TWI) were determined. Handedness was determined by a questionnaire that focused on handedness using the Turkish version of the Edinburgh Handedness Inventory.ResultsThis study showed that there were no statistically significant differences between groups I and II according to daily tooth-brushing habits, PI, or GI. Statistically significant differences were found between men and women according to the clinical oral scores and brushing habits (P<0.01). However, there were no statistically significant differences between the mean TWI scores of left- and right-handed groups (P=0.12). It was found that an increased frequency and longer duration of tooth-brushing significantly increased the TWI scores in both groups (P<0.01). It was also found that TWI scores were statistically higher in subjects who brushed horizontally rather than vertically (P<0.01). Correlations between clinical oral scores (TWI, PI, and GI) and brushing habits were statistically significant (P<0.01).ConclusionThe oral-hygiene performance of females was better than males. Brushing habits of patients were related to the severity of cervical wear. But no statistically significant relationship was found between hand preference and tooth-brushing abrasion in this study

Physical and chemical properties of recently deposited sediments in the reservoir of the Borcka Dam in Artvin, Turkey

This study was supported by the Department of Scientific Research Projects of Artvin Coruh University (Project Number: 2013.F12.02.03).Large dams produce important changes in flow regime and sediment deposition and distribution in rivers. When inundation starts with the building of dams, water surface area increases, flow rate decreases, and sediment carried by the river is deposited in the reservoir. However, there is a lack of research on the physical and chemical properties of recently deposited sediment in reservoirs of large dams. We aimed to fill this gap in the literature by providing valuable data on the initial formation of sediment deposition areas in reservoirs. Therefore, the aim of this study conducted within the Borcka Dam reservoir was to estimate some physical and chemical properties of deposited sediment, including grain size distribution, penetration resistance, water-stable aggregate, moisture content, organic matter content, and pH at two depths (0-10 cm and 10-20 cm). Another objective was to analyze the distribution of these properties across the sampling site. For this purpose, one of the aforementioned sediment deposition areas, approximately 3.6 ha, was designated as the study site; the study site was further divided into intersecting transects of 10 x 50 m. The penetration resistance values were determined in the field and 182 sediment samples were taken at 91 intersection points of transects, both from the surface (0-10 cm) and subsurface (10-20 cm) layers for laboratory analysis. Data gathered were evaluated using descriptive statistics and ANOVA, while geostatistical analyses were used for calculating spatial variability in the data. Results indicated that the most common texture classes were loam in the surface layer and silty loam in the subsurface layer. Moreover, the penetration resistance values, sand content, and water-stable aggregate values in the surface layer were significantly (P < 0.01) higher than in the subsurface layer, and moisture content, clay and silt content, pH, and organic matter were significantly (P < 0.01) higher in the subsurface layer than in the surface layer. Geostatistical analyses showed that all properties were described by the isotropic variogram and the ranges were lower in the subsurface layer than in the surface layer. This study revealed that the analyzed physical and chemical properties of the recently deposited sediments showed significant differences between the layers

Determining spatial variability of penetration resistance and particle size distribution in sediment deposition

Erosion and sedimentation in dam reservoirs may result in both ecological and economic problems. That is why, besides its amount, it is important to know physical and chemical properties of sediment accumulated in reservoirs. Thus, it is possible to gather information regarding erosion and parameters affecting the erosion process in a watershed. Determining particle size distribution generally comes first when investigating physical properties of sediments. Despite similar texture formation, compaction degree of sediment layers increases due to repacking of particles with time. It is important to figure out compaction degree of sediment layers in accumulation sites and measuring penetration resistance is one of the techniques used mostly. This study was initiated in one of 9 sediment deposition sites determined along the Borcka Reservoir. Precipitation periods within the watershed of the reservoir and power generation cycles of the dam play an important role on the formation of these sedimentation sites. At the first stage of the study, lateral profile distribution and depth of sediment deposition were determined. Then, on sampling points, arranged by the grid system, penetration resistance was measured. In addition, disturbed sediment samples taken from the same sampling points at two depths (0-10 cm and 10-20 cm) were analyzed for moisture and particle size distribution. Geostatistical analyses were used on these values in order to produce spatial variation maps while regression was used to assess relationships between parameters investigated in this study. Results indicated that there were significant differences between layers in respect to penetration resistance values and particle size of sediments and it was found out that spatial variation of penetration resistance closely related with particle size distribution

Investigation of the effect of working capital management on profitability by panel data analysis and multi-criteria decision making techniques

Purpose: The aim of this study is to reveal and compare the effect of working capital management on return on assets with different analysis methods, based on the annual financial statement data of companies in the tourism sector traded in Borsa Istanbul (BIST) in the period 2012-2020. This study aimed to reveal the drawbacks of including in the model variables that are not an element of working capital management. Methodology: Panel data analysis, the analytical hierarchy process and the fuzzy analytical hierarchy process were used to reveal the effect of working capital management variables on return on assets based on the financial statement data of the companies. Results: As a result of the analysis, a significant relationship was identified between the rankings made by using the realized return on assets ratios and the rankings obtained by AHP and FAHP, while no significant relationship was found between the rankings obtained by panel data analysis. Conclusion: Including some variables in the model as a working capital management variable in panel data analysis may cause misinterpretation of the effects of real working capital variables on return on assets. When the model that emerged according to the AHP and FAHP methods was examined, the asset turnover rate and financial leverage ratio variables were determined as the ratios with the lowest effect on return on assets, as the elements of working capital management in the weighting made according to the opinions of the experts

Serum procalcitonin and cerebrospinal fluid cytokines level in children with meningitis.

AIMS: To determine the level of serum procalcitonin and cerebrospinal fluid cytokines in children with bacterial or viral meningitis and to document the use of these parameters in differential diagnosis. RESULTS: Before the start of antibiotic treatment, serum procalcitonin and tumor necrosis factor alpha levels were found to be higher in acute bacterial meningitis compared with viral meningitis and with the control group. Similarly, cerebrospinal fluid interleukin-6 levels were found to be significantly higher in children with acute bacterial meningitis compared with viral meningitis. However, no significant difference was determined between groups in respect to the cerebrospinal fluid interleukin-8 level. CONCLUSION: Serum procalcitonin and cerebrospinal fluid tumor necrosis factor alpha levels can be used in the early diagnosis of bacterial meningitis. Similarly, they may be useful adjuncts in differential diagnosis of bacterial and viral meningitis

Unusual Idiopathic Calcinosis Cutis Universalis in a Child

Calcinosis cutis is an uncommon disorder characterized by the progressive deposition of crystals of calcium phosphate (hydroxyapatite) in the skin in various areas of the body. It is classified into four types according to etiology, namely as dystrophic if calcium and phosphorus levels are normal and tissue damage is present, as idiopathic if calcium and phosphorus levels are normal and no tissue damage is present, or as metastatic if there is hypercalcemia or hyperphosphatemia. Medical and surgical treatments are options to cure calcinosis cutis. Medical therapy is not very effective. Surgical excision has shown to be beneficial, as it can provide a symptomatic relief. However, since calcinosis cutis limits are not always well defined, a recurrence of the lesions may occur. We dealt with a very rare form of calcinosis cutis in a healthy 6-year-old girl. There was no evidence of connective tissue disorder or abnormal mineral metabolism. Hence, she was diagnosed as idiopathic calcinosis cutis and, although calcifications in idiopathic cutis are most commonly localized to one area, our patient unusually exhibited widespread calcific deposits. Although the existing lesions showed slow improvement, systemic pamidronate therapy was effective in preventing the occurrence of new lesions. Surgical excision proved to be an effective and successful treatment. This report aims to raise doctors’ awareness on the presentation, etiopathogenesis, and course of the relatively rare idiopathic calcinosis cutis
