The Perception Analysis of Cyber Crimes in View of Computer Science Students

AbstractComputer Technologies growing rapidly has become an indispensable part of modern life. While making social life easier, the changes that technology has brought also bring forth some security issues. Thus, it is easier to commit crimes and we are faced with cyber-crimes. This study examines the differences among the cyber-crime perceptions of undergraduate students at Trakya University in terms of demographic factors. The method of the study was a questionnaire that was given to lecturers and students at Trakya University sample and it was designed to measure and assess the levels of interest in technology, the severity of cyber-crimes and the individuals’ perceptions of cyber-crimes in terms of ethics and law. The findings of the study can help us define the level of common perception of cyber-crimes and the meaningful differences between separate groups

Systemic Sclerosis

Systemic sclerosis (SSc) is a chronic, autoimmune disease which can affect the blood vessels, the visceral organs, and the skin. SSc, most commonly, develops between the ages of 30 and 50, but it can be seen at any age. In terms of skin involvement, SSc can be classified as limited or diffuse. Its etiopathogenesis is still unclear. Microvascular dysfunction is thought to be followed by immunological activation, collagen and extracellular matrix deposition, and finally fibrosis. Diagnosis is based on clinical presentation. Sclerosis of the metacarpophalangeal and/or metatarsophalangeal joints is the major diagnostic criterion, whereas sclerodactylia, digital ulcers (DU), and pulmonary fibrosis are the minor criteria. SSc is diagnosed with one major criterion or two minor criteria. Detection of autoantibodies can help the diagnosis. Antinuclear antibody (ANA), anti-centromere antibody, anti-scl 70, RNA polymerase 1 and 3, and anti-fibrillin antibody can be found positive in SSc. SSc must be differentiated from all sclerosing diseases and the diseases with Raynaud’s phenomenon. Visceral diseases, such as primary pulmonary hypertension, primary biliary cirrhosis, and infiltrative cardiomyopathy, should also be considered in its differential diagnosis. The main treatment goal is to target visceral involvement

A Review on Plasma Gasification of Biomass and Conversion to Jet Fuel

Aviation sector is growing rapidly. Several organisations have determined targets to decrease GHG emissions in aviation by replacing fossil fuels with renewable bio-jet fuels. To meet these targets, the most suitable pathway is waste/biomass to jet fuel conversion. In this review, plasma gasification of waste/biomass is investigated. Then, three alternative conversion methods from syngas to jet biofuel which are state of the art or beyond, are briefly examined. When comparing the overall energy efficiencies of the three conversion methods, the values are determined to be 45% for Fischer-Tropsch (FT), 57% for gas fermentation (GF) and up to 67% for syngas to gasoline plus (STG+). FT and GF methods have a technology readiness level near to pre-commercialization.  But, among the three methods, STG+ is evaluated to be the most appropriate and simple process in all scales except the technology readiness level. Further studies are needed to maturate the STG+ technology to commercialization. Keywords: waste, biomass, plasma gasification, bio-jet fuel, advanced biofuel, next generation biofuel technologie

Internet Addiction and Its Impact on Physical Health

DergiPark: 439213tmsjAims: Internet addiction, a recently emerged term in medical literature, has significant physical effects on the young generation. In this research, controversial effects of internet addiction on physical health have been investigated among the students of Trakya University School of Medicine, who constitute a part of the population at risk. Methods: The study included 327 medical students. The correlation between internet addiction and physical complaints associated with internet usage and its relation with gender, purpose and duration of internet usage were investigated. The data were obtained by using surveys and Internet Addiction Scale. To evaluate the data; descriptive statistics, Correlation, Mann-Whitney U tests, Cronbach alpha methods and survey with 16 questions were used for statistical analysis. Results: There is a statistically significant difference in terms of Internet Addiction Scale score between internet addiction and physical complaints such as headache, feeling of stiffness, backache, neck pain and insomnia. Internet Addiction Scale score and time spent on the internet showed a statistically significant correlation. Conclusion: Increase in internet usage leads to many physical health problems, which may cause serious and permanent damage to physical health. Therefore, the required attention must be given to this subject especially for the benefit of younger generation

The effects of the parameters that play an important role in the EC process efficiency such as pH, current density (C.D.) and electrolysis time (E.T.) for the removal of the COD (Chemical Oxygen Demand) and TDS (Total Dissolved Solids) by EC process were determined. Box-Behnken Statistical Model was used in experimental design. Statistical analyzes show that the results for both pollutants match the quadratic model. The coefficient of determination (R2 ) value for removal of COD and TDS in the EC reactor, was found to be 0.95 and 0.99, and R2 Adj value was found to be 0,88 and 0,99, respectively. Being R2 and R2 adj values close to 1 indicates that the experimental results and statistical inferences were compatible and the Box-Behnken statistical design was effective in order to determine the effects of process parameters. The optimum pH values for COD and TDS removal were determined as 6.51 and 6.4 respectively, whereas the optimum current density for both pollutants was 59 A / m2 and the electrolysis time was 29 minutes
