Hisse Senedi Fonlarında Karşılaştırma Ölçütü Seçiminin Etkinliği
No full textBu çalışmada, Borsa İstanbul’daki hisse senedi fonlarının, karşılaştırma ölçütü seçimlerini ne derece etkin yaptığı araştırılmıştır. 26 adet fonun dahil edildiği araştırmada 2010 ve 2020 yıllarını kapsayan 11 yıllık veri kullanılmıştır. Çalışmada bağımlı değişken olarak hisse senedi fonlarının günlük getirileri, bağımsız değişken olarak ise BIST100 ve XTUMY endekslerinin performansları kullanılmıştır. Çalışmadan elde edilen sonuçlara göre fonların çoğunluğu, karşılaştırma ölçütü olarak BIST100 ve BIST30 endeksini seçmektedirler. XTUMY endeksinin hiçbir fon tarafından karşılaştırma ölçütü olarak seçilmemiş olmasına rağmen 14 adet fonun 2016-2020 arası dönemde XTUMY endeksi ile ilişki katsayısının 0,1’in üstünde olduğu görülmektedir. Araştırma sonuçları XTUMY endeksinin performansının fonlar için önemli bir faktör olduğunu ve bu endeksin karşılaştırma ölçütü formülünde birleşenlerden biri olarak yer alması gerekliliğini ortaya çıkarmıştır
ANONİM ŞİRKETLERDE ASGARİ SERMAYE ZORUNLULUĞU VE TÜRK TİCARET KANUNU M. 332/1 HÜKMÜNÜN DEĞERLENDİRİLMESİ
No full textSınırlı sorumluluk ilkesinin kabul edildiği anonim şirketlerde pay sahiplerinin, yalnızca şirkete getirmeyi taahhüt ettikleri sermaye ile sorumlu olmaları şirket alacaklıları bakımından korunma ihtiyacını doğurmuştur. Bu ihtiyaç sebebiyle özellikle Kıta Avrupası ülke hukuklarında kabul edilen esas sermaye sistemi, sermayenin oluşturulması ve sermayenin korunması sütunları üzerine inşa edilmiş olup, asgari sermaye zorunluluğu ile kuvvetlendirilmiştir. Asgari sermaye zorunluluğunun menfaat sahiplerinin korunmasında kendisinden beklenen işlevleri yerine getirebilmesi ancak uygun bir miktarın tespiti ve bu miktarın sermayenin korunması hükümleri ile verimli bir şekilde korunabilmesi ile mümkündür. Günümüzde 6102 sayılı Türk Ticaret Kanunu’nun (TTK) “en az sermaye tutarı” başlıklı m. 332/1 hükmü ile belirlenmiş olan 50.000 TL asgari sermaye miktarının, bir anonim şirketin kuruluşu için yeterli, hileli eylemleri ve paravan şirket girişimlerini caydırıcı ve yeni girişimleri teşvik edici nitelikte olmadığı söylenebilir
Relationship Between Cognitive Flexibility, Anxiety Sensitivity and Coronaphobia
No full textObjective: In this study, it was aimed to determine relationship two transdiagnostic factors (anxiety sensitivity and cognitive flexibility) between Coronavirus-19 (COVİD-19) phobia. Method: For the study, the forms were sent to social media groups with 4,000 and 3,500 people on social media, and the participants were selected by the simple random sampling method. 280 volunteers who met the inclusion criteria were accepted. Sociodemographic Data Form, Cognitive Flexibility Inventory (CFI), Anxiety Sensitivity Index-3 (ASI-3), COVID-19 Phobia Scale was used to evaluate the volunteers. Result: 161 male and 101 female volunteers participated in the study. Both sexes have similar characteristics regarding age, marital status, and years of education. In the correlation analyses, positive correlations were found between coronaphobia scale total scores and ASI- physical (r=.584), ASI- cognitive (r=.556), ASI- social (r=.524), ASI-total (r=.609), whereas a negative correlation was found between coronaphobia scale total scores and CF-alternatives (r=- .232), CF-control (r=-.375), CF-total (r=-.328). Stepwise regression analysis was applied with ASI and CFI subscales to predict coronaphobia scale scores. According to the results, ASI-physical (?=.287), ASI-cognitive (?= .178) positive and CF-control (?=-.148) negatively predicted coronaphobia total scores significantly {F(7, 254) = 23,361, p < .01) , with an R2 of .375 Discussion: Our results were shown that sub-tpye of transdiagnostik factors were more closely related to coronophobia and even predicted
Opinions of cardiologists on class II recommendations in current European Society of Cardiology 2018-2020 guidelines: YELLOW BOX
No full textObjectives: We planned our survey study to evaluate the opinion of cardiologists about the class II recommendations on levels of evidence in the current European Society of Cardiology Guidelines (ESC). Our aim is to determine which diagnosis or treatment option most prefer by cardiologist when guidelines do not make clear recommendations.Methods: The survey was conducted on September 2020 with the participation of cardiologists (n = 102).Our survey covers ESC's guidelines published in 2018-2020 on diagnosis and treatment strategies in coronary artery disease, diabetes, heart valve disease, arrhythmia, dyslipidemia and heart failure. Our survey consisting of 40 questions was shared with the cardiologists via e-mail. Results: Participants answered all of the survey questions. The majority of the participants (79.41%) did not consider the addition of a second long-term antithrombotic medication in addition to aspirin for secondary prevention in diabetes mellitus (DM) and coronary artery disease (CAD) patients who are not at high risk of bleeding. The lowest low density lipoprotein (LDL) value achieved by the participant physicians with treatment in their practices was < 40 mg/dl in 32 (31.37%) participants . One of the striking results of the survey was that 51.96% of the participants stated that it was not possible to measure the lipoprotein a (Lp(a)) level in the center where they were carrying out their practices, and 34.31% did not consider the Lp(a) level in the treatment of dyslipidemia in terms of directing the treatment. As for patients with asymptomatic Wolff-Parkinson-White (WPW) syndrome, 58.82% of the participants considered catheter ablation therapy.Conclusions: Although there were different opinions on some recommendations, the participants were mostly in agreement. We think that these survey results, which were mostly based on expert opinions, may contribute to the guidelines to be published in the future with the increase of survey studies on these issues
NEW HEMATOLOGICAL PARAMETERS AS EARLY DIAGNOSIS AND PROGNOSTIC MARKERS IN CRITICALLY PATIENTS
No full textINTRODUCTION: Nucleated red blood cells and immature granulocytes are not normally detected in the blood of healthy adults. We aimed to investigate the effect of nucleated red blood cells and immature granulocytes on mortality in order to identify critically ill patients who were admitted to the emergency department, at high risk of death, and who was not traumatic. MATERIAL AND METHODS: This study was performed retrospectively in the emergency department of a tertiary education and research hospital between January 2021 and June 2021. All patients who died out of trauma and patients who were discharged from the emergency department on the same day were included. Nucleated red blood cells and immature granulocytes parameters were compared between the two groups. The primary outcome was all-cause death in the emergency department. RESULTS: Of the 188 patients included in the study, 129 (68.6%) were male. Nucleated red blood cells (1.88 ± 6.9/?L; 0.02 ± 0.08), % immature granulocytes (2.91 ± 3.04/?L; 0.58 ± 1.63) and immature red blood cells in deceased patients' granulocyte count (0.38 ± 0.46/?L; 0.04 ± 0.04) was significantly more significant than the control group (p < 0.001). When the area under the curve was examined, the highest value was found in nucleated red blood cells (Area under the curve = 0.920, p < 0.001). In multivariate regression analysis, high nucleated red blood cells, immature granulocyte count, and white blood cell levels were associated with all-cause mortality in the emergency department. CONCLUSIONS: High nucleated red blood cells and immature granulocyte levels may be associated with increased mortality during admission to the emergency department. Copyright © 2022 Via Medica
ECZACILIK FAKÜLTESİ ÖĞRENCİLERİNİN TÜBERKÜLOZA İLİŞKİN FARKINDALIK VE BİLGİ DÜZEYLERİNİN DEĞERLENDİRİLMESİ: BİR VAKIF ÜNİVERSİTESİ ÖRNEĞİ
No full textObjective: Tuberculosis (TB) is an infectious disease that is among the leading causes of death. TB can easily spread by aerosols from pulmonary TB patients. Pharmacists are unique among healthcare professionals because patients can easily and directly access them. Therefore, they have to take responsibility for management and early detection of TB. The aim of this study was to evaluate TB related awareness and level of knowledge of pharmacy students in a foundation university. Material and Method: This cross-sectional study was conducted to evaluate the knowledge and attitudes of undergraduate pharmacy students about TB. A face-to-face survey was made to students in their classrooms after ethical committee’s approval was received and verbal consent of participants obtained. A total of 238 students answered the survey. Descriptive statistical methods and Pearson Chi-Square test are used for the evaluation of the data. Result and Discussion: We found that all of the students knew tuberculosis, but some of them lacked knowledge on some topics such as the symptoms of the disease, risk factors, definitive diagnosis, and drug resistance rates. Pharmacists who have an important role in public health should be informed and advised to be updated about TB during their undergraduate education. In addition, it should be ensured that they take responsibility to raise public awareness of TB which causes thousands of deaths each year. © 2022 Authors. All rights reserved
EVLENME YOLU İLE TÜRK VATANDAŞI OLMA TALEPLERİNDEN DOĞAN UYUŞMAZLIKLARA İLİŞKİN YARGILAMALARDAMİLLİ GÜVENLİK VE KAMU DÜZENİ KISTASI
No full text5901 sayılı Türk Vatandaşlığı Kanunu m.16/ı-c’de yer verilen milli güvenlik ve kamu düzeni kıstasının evlenme yolu ile vatandaşlık oluşumunda nasıl bağdaştırılacağının tespiti önem arz etmektedir. Milli güvenliğin tehdit unsurlarına dair net kriterler getirilmedikçe İçişleri Bakanlığının takdir kararının mahiyetini denetlemek güçleşmektedir. Aynı bakış açısından kamu düzeni kavramının da uygulayıcıların görüş ve anlayışlarına göre genişleyebilecek, öznel yoruma elverişli bir kavram olarak keyfiliğe vardırılması mümkün hâle gelmektedir. Milli güvenlik ve kamu düzeni bakımından engel teşkil etmeme hâli, evlenme yolu ile Türk vatandaşı olmak isteyen yabancılar bakımından başvuru şartı değil; başvurudan sonra ele alınan bir değerlendirme kıstasıdır. TVK m.16’daki başvuru şartları, ancak Türkiye’de ikamet etme şartı ile desteklenirse milli güvenlik ve kamu düzeni bakımından engel teşkil edecek bir hâli bulunmama kıstasından beklenen faydanın ortaya çıkacağı düşünülmektedir

The aim of this study is to serve as an educational guide of current trends in TPD for foreign language educators, which can be utilized to fabricate a program that should feed individuals both internally and externally
The evaluation of disease awareness, caregiver burden, and workday loss in caregivers of COPD patients
No full textBackground/aim: Our aim is to determine the caregiver burden of chronic obstructive lung disease (COPD) patient's caregivers, and to determine whether there is a workday loss. Materials and methods: 252 COPD patients and their caregivers were included. Disease information of the patients were recorded and a questionnaire was applied. Socio-demographic characteristics of the caregivers were recorded and a questionnaire consisting of 24 questions including COPD disease, treatment and loss of working days, and the Zarit Scale were used. Results: 128(50.8%) of the patients according to GOLD were group-D, 97(38.5%) of the patient's relatives were working, 62(24.7%) were not able to go to work for 1-14 days, and 125(57.1%) spent outside the home from 1-14 nights, because those accompanied to patients. In univariate analysis were detected modified medical research council (mMRC) (p < 0.001), CAT (p < 0.001), the number of comorbidities of patients (p = 0.027), forced expiratory volume in 1 FEV1cc (p = 0.009), FEV1% (p < 0.001), the presence of long term oxygen therapy (LTOT), and the number of comorbidities of the patient's relatives (p = 0.06) increased the care load. In multiple linear regression analysis, age (p = 0.03), COPD assessment test (CAT) score (p = 0.001), FEV1% (<0.068) and the number of comorbidities of patients (p = 0.01) and the number of comorbidities of caregivers (p = 0.003) increased the caregiving burden. Conclusion: In COPD increases caregiving burden. This burden is greater in symptomatic patients and when comorbidities are present. Psychosocial and legal regulations should be investigated and solutions should be produced for the caregivers of COPD patients
