Examining the Academic Success of the Students in Drawing Techniques Course: The Case of Freshmen in Landscape Architecture
In Landscape Architecture education the students are expected to produce a unique and creative product and express this product in two or three dimensions. For this aim drawing techniques related to visualizing the design are instructed in the first year of landscape architecture education in the Drawing Techniques course using conventional methods of expression. As a result, the students can express themselves and acquire the ability to use the lines and the pencil. Knowing how to draw enables students to obtain basic knowledge about what to express and how; acquiring the ability to use the pencil provide them the opportunity to draw quality images - good sketches. After learning these skills, it will become easier for them to transfer their thoughts to digital media and to express their designs in digital media. In Landscape architecture education, to improve freshmen's technical drawing skills, practices related to two (plan, profile-view) and three (perspectives) dimensional drawing techniques are conducted within the scope of Drawing Techniques course. In the present study, the practices that are implemented by freshmen who took Drawing Techniques course during five semesters between 2012-2017 academic years were examined. The change in the drawing performance of the students in practices was analyzed. It was also examined whether the two or three dimensional drawing techniques led to this change and whether the type of drawing techniques utilized affected their level of making mistakes and the variety of those mistakes
Examination of Agression of University Students by the Level of Playing Sports
The aim of this research is to examine aggression of university students by the level of playing sports. 215 students constituted the sample of this study. Personal information form and âAggression Scaleâ were used as a data collection tool. Mann-Whitney U Test and Anova Test were performed for difference between groups and Cronbachâs Alfa (,898) was performed in order to measure reliability of data concerning scale (p<0.05).As a conclusion; it was determined that sport is effective on the aggression level of university students. It was stated that the average aggression level of people who play sports is lower than people who donât play sports. As there is no difference between ways of playing sports, there is a difference between departments. Males have higher aggression level than females. It is possible to say that sport has aggression reducing effect besides health and entertainment benefits in the direction of these findings
Vitamin D Deficiency and Chronic Widespread Pain
Vitamin D acts as a steroid hormone possessing important functions in calcium and phosphorus balance and bone health. The presence of vitamin D receptors (VDRs) in many tissues in the human body shows that this vitamin might have effects other than its role in maintaining bone health. Hence, many studies in the last two decades have reported an association between vitamin D deficiency and many musculoskeletal and extra-skeletal diseases. Despite the presence of clear evidence suggesting a causative relationship between musculoskeletal pain and osteomalacia developing as a result of long-term and severe vitamin D deficiency, a putative relationship between vitamin D deficiency and chronic widespread pain (CWP) has recently been an exciting area of discussion. The hypothetical role of vitamin D in the pathophysiology of pain, the availability of VDRs in the muscle tissue and central nervous system, particularly in the hypothalamus, and the reports on the development of muscle hypersensitivity associated with vitamin D deficiency, have provided a basis for a putative relationship between CWP and vitamin D status. This review will discuss these two problems that commonly occur within the general population, and endeavour to reveal this relationship in light of currently available studies
Ultrasonic treatment of biologically treated bakerâs yeast effluent
The aim of this study was to examine the removal of color and chemical oxygen demand COD of biologically treated bakerâs yeast effluent with ultrasonic irradiation. An ultrasonic homogenizator with 20 kHz frequency was used for this purpose. TiO2/ZnO composite was used as a sonocatalyst. The effect of the amount of catalyst on color and COD removal was investigated. According to results, by using ultrasound and TiO2/ZnO composite, decolorization increases until the optimum of the catalyst amount. The highest decolorization was obtained at 0.15 g/L of catalyst concentration. COD removal was 17% with ultrasonic irradiation and increased to 33% when using ultrasound along with the catalyst at the optimum amount. The effect of the solution pH on ultrasonic decolorization was also investigated in this stud
A Long View of Shareholder Power: From the Antebellum Corporation to the Twenty-First Century
For most of the twentieth century, the conventional wisdom heldâprobably correctlyâthat shareholders in Americaâs large, public corporations were passive and powerless and that managers wielded the real power. Beginning in the 1980s, however, shareholders in the form of institutional investors started to push for a greater say in corporate decision-making. In the twenty-first century, hedge funds have upped the ante, fighting for major changes in corporations whose shares they own. Once-imperial CEOs have now become embattled as they fight, but often lose, against activist shareholders demanding policy changes, new dividends, board representation, and even the sale or break-up of corporations. In short, things have changed.
This Article situates the present-day rise of shareholder power by taking a long view of the previous two centuries, moving beyond traditional accounts to reach all the way back to the beginnings of the American business corporation in the early nineteenth century, then following the story of shareholder power up to the present day. Its long view reveals the complicated and shifting nature of shareholder power, documenting how periods of greater shareholder power were interspersed with periods where shareholders had little power, how the focus of shareholder power has moved from controlling shareholders to autonomous managers, and how shareholder power has ebbed and flowed across the last two centuries. This Article not only provides the backstory to present-day developments, but also suggests that what has appeared as a hallmark of American corporate capitalismâthe relative powerlessness of shareholdersâmay only have been typical of a few decades in the middle of the twentieth century.\u3c.p\u3
Evaluation of e148q and concomitant aa amyloidosis in patients with familial mediterranean fever
The aim of the study was to compare the clinical phenotype of patients with familial Mediterranean fever (FMF)-related AA amyloidosis, according to the age of FMF diagnosis and E148Q genotype. Patients with biopsy-confirmed FMF-related AA amyloidosis were included in the study. Tel-Hashomer criteria were applied in the diagnosis of FMF. All patients had detailed baseline assessment of clinical features, renal functions, genetic testing, histopathological diagnosis of amyloidosis, and treatment received. Multiple comparisons were performed according to the age of diagnosis, disease phenotype, mutation, and mortality. Our study included 169 patients with a diagnosis of AA amyloidosis. There were 101 patients diagnosed with FMF \u3c 18 years of age and 68 patients diagnosed who were â„18 years of age. The three most common clinical manifestations were fever (84.6%), abdominal pain (71.6%), and arthritis (66.9%). The most common allele among FMF patients was M694V (60.6%), followed by E148Q (21.4%), and M680I (10.3%). The most frequent genotypes were M694V/M694V (45.0%), M694V/E148Q (14.8%), and E148Q/E148Q (11.2%) among 169 patients in our cohort. During the follow-up period, 15 patients (10 male, 5 female) died, of whom 14 had M694V homozygous genotype and one was homozygous for E148Q. Clinicians should be aware of patients with homozygous E148Q genotype for close monitoring and further evaluation. The possible relationship between E148Q and AA amyloidosis needs to be confirmed in other ethnicities
Synthesis and In vitro Antimicrobial Activity of Novel 2-(4-(Substituted-carboxamido)benzyl / phenyl)benzothiazoles
A new series of 2-[4-(4-substitutedbenzamido / phenylacetamido / phenylpropionamido) benzyl
/ phenyl]benzothiazole derivatives (6aâ6w) were synthesized and evaluated for antibacterial and antifungal
activities against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, Pseudomonas
aeruginosa, Escherichia coli with their drug-resistant isolates and a yeast Candida albicans. Microbiological
results indicated that the compounds possessed a broad spectrum of activity against the tested microorganisms
at MIC values between 200 and 6.25 ÎŒg/ml. Compounds 6e and 6j exhibited the greatest activity
with MIC values of 6.25 ÎŒg/ml against Pseudomonas aeruginosa, and Staphylococcus aureus isolate,
respectively.(doi: 10.5562/cca2064
Antibiotic Susceptibility of Lactic Acid Bacteria Isolated From Cow, Goat, Donkey, Buffalo, Sheep, Camel and Human Milk
Breast milk is a very important factor in regulating gastrointestinal function, improving the immune system and preventing acute illnesses (e.g. acute otitis media), especially during breastfeeding. Breast milk allows beneficial bacteria such as bifidobacteria and lactobacillus species to colonise the newborn intestin*e instead of potential enteropathogenic bacteria such as streptococci and escherichia coli. The aim of the study was to compare the antibiotic resistance of Lactic acid bacteria members isolated from different milk samples. Six milk samples were collected from each of seven different milk sources (donkey, goat, cow, buffalo, sheep, camel and human). The MRS and M-17 medium were used with the double layer sandwich method for isolation of LAB members selected from typic colonies, gram-positive, catalase-negative used in the study. The isolated 42 LAB species were determined antibiotic susceptibility with 9 standart antibiotic discs such as tetracycline, penicillin, kanamycin, streptomycin, rifampin, gentamicin, chloramphenicol, teicoplanin, ciprofloxacin by agar disc diffusion assay test. The 18 LAB isolate were resistant to penicillin, 16 isolate to kanamycin, 14 isolate to gentamicin. LAB isolates such as H1, H4, H5 from Human milk and LAB isolate such as D1 from donkey milk was considered as MDR isolates because they were resistant to at least four of the tested drugs. Among the milks, sheep, camel, buffalo and goat milks were found to be more sensitive to antibiotics on average in the group
Chemerin as a marker of subclinical cardiac involvement in psoriatic patients
Background: Chemerin has been associated with psoriasis and inflammation, but there are no studies demonstrating an association between chemerin and subclinical cardiac involvement in psoriatic patients. Therefore, the present study aimed to evaluate whether psoriatic patients with increased epicardial fat tissue, impaired flow-mediated dilatation, and diastolic dysfunction have higher serum chemerin levels than a healthy control group.
Methods: The study included 60 psoriatic patients and 32 healthy controls. Echocardiographic parameters, epicardial fat tissue, flow-mediated dilatation, and chemerin levels were recorded for both groups.
Results: The serum levels of chemerin in the psoriatic patients were significantly higher than in the control group. The diastolic function parameters, including isovolumic contraction and relaxation time, Eâ/Aâ (early diastolic mitral annular velocity/late diastolic mitral annular velocity), and E/Eâ (early diastolic peak velocity of mitral inflow/early diastolic mitral annular velocity) values, differed significantly between the groups. Epicardial fat tissue was significantly higher and flow-mediated dilatation was significantly lower in psoriatic patients than in the controls. Chemerin was significantly positively correlated with age, body mass index, systolic and diastolic blood pressures, waist circumference, E/Eâ, and epicardial fat tissue. Serum chemerin was significantly negatively correlated with Eâ, Eâ/Aâ, and flow-mediated dilatation. A multiple linear regression analysis showed that chemerin was independently correlated with E/Eâ.
Conclusions: Psoriatic patients exhibit early subclinical atherosclerosis and diastolic dysfunction. Chemerin can be used as a marker to screen for patients with subclinical cardiac involvement
