Factors Affecting Students Grades In Principles Of Economics

Factors affecting students grades in principles of microeconomics and macroeconomics students are analyzed from the data collected in two public universities. Results indicate that gender, number of hours worked, SAT scores, number of missed classes, recommending the course to a friend, instructors, being a junior, number of economics courses taken, course, and interest in the course, were significant factors contributing to learning and success as measured by grades. Moreover, GPA, age, staying in university housing, number of mathematics classes taken, instructors use of graphs to explain a topic, being a fourth year student, enrolling for a class because of the reputation of an instructor had positive effect on students grades, while the effect of the number of hours per week spent on studying for the class was negative

Kestane kabuğu, ısırgan otu, kivi meyvesi ve narenciye özütlerinin antioksidan potansiyelleri ve bazı balık patojenlerine karşı antibakteriyel etkileri

The use of antioxidants and antibacterial compounds obtained from natural sources is important for human and animal health, as well as for controlling diseases. The aim of this study was to evaluates the antioxidant potentials and antibacterial effects of water extracts of C. sativa, U. dioica, A. deliciosa and C. aurantium against selected Gram-negative (Vibrio harveyi, Vibrio vulnificus, Vibrio anguillarum, Vibrio rotiferianus, Vibrio campbellii, Vibrio ponticus and Aeromonas veronii) and Gram-positive (Bacillus thuringiensis) bacteria. Results of antioxidant test indicated that the chestnut shell extract had the highest DPPH inhibition (87.03 %) followed by citrus fruit (80.40 %). All extracts showed antibacterial activity against one or more species of bacteria. The most susceptible bacteria were V. harveyi (32.05 mm zone diameter) and V. campbellii (21.66 mm zone diameter) and the resistant species were V. anguillarum, V. ponticus and A. veronii. The results show that plant extracts have the potential to be used as an antibacterial agent in aquaculture and as an antioxidant agent in processing technology.Doğal kaynaklardan elde edilen antioksidan ve antimikrobiyal bileşiklerin kullanımı, insan ve hayvan sağlığı için olduğu kadar hastalıkların kontrolü açısından da önemlidir.

Otolaryngology Residents’ Attitudes, Experiences, and Barriers Regarding the Medical Research

Objective:It was aimed to investigate the attitudes, experiences, and barriers towards scientific research among otolaryngology residents in Turkey.Methods:Anonymous data were collected via an online survey. The demographic characteristics and experience in scientific research were investigated in the first section of the survey. The attitudes of participants towards scientific research and the barriers to the scientific research were examined in the second section of the survey using 17 items.Results:The present study involved 119 otolaryngology residents continuing their education. It was determined that 68.1% of participants think that “participating in scientific research” is a part of otolaryngology training. In the present study, it was shown that the residents having journal club hours in clinics on regular basis participated in various steps of scientific research projects (p<0.05). Residents stated that they participated in the “literature review” stage of the preparation of a scientific publication (mean value of 2.58±1.88) most and in “verbal presentation in a congress” least (mean value of 0.74±1.44). It was determined that 80.7% of participants have not attended in any training on scientific research. It was found that the residents receiving structured scientific research training participated more in steps of scientific research projects which was statistically significantly (p<0.05).Conclusion:In our country, otolaryngology residents are very enthusiastic about having research education and participating in researches. However, residency students frequently have time deficiency, lack of knowledge-skill, and lack of financial support. Dedicated time should be allocated for research training and practice in specialty programs. Journal club activities should be organized on regular basis and integrated with research education. On the other hand, the scholarly activities of residents should be supported by means of various countrywide educational activities on research training

Allergy Practices in Otorhinolaryngology Residency Programs in Turkey: Quo Vadis?

Objective:The aim of this study was to investigate how allergy practices in the otorhinolaryngology (ORL) residency departments in Turkey have changed over the last 20 years and to examine the current status in ORL residency training.Methods:A 17-item questionnaire was developed following the study goals by a team experienced in allergy practices. The questionnaire was sent via e-mail to the program directors of all the 95 ORL residency departments in Turkey.Results:A total of 60 (63.2%) program directors completed the questionnaire. We found that allergy testing and immunotherapy had been performed in 70% and 28.3%, respectively, at any time to date. The most common reason for discontinuing in allergy practices over time was “the changes introduced by the Turkish Social Security Institute as stated in the healthcare implementation communiqué” and “the difficulties in obtaining vaccine supplies from companies”. Of all departments, allergy testing, immunotherapy, nasal smear, and nasal provocation tests were performed only by 35%, 8.3%, 28.3%, and 1.7%, respectively.Conclusion:Allergy practices have been increasingly used, especially in the 2000s, but came to a standstill upon the changes introduced by the Turkish Social Security Institute as stated in the healthcare implementation communiqué. These findings suggest that allergy training, in the recent years, has remained in the background in ORL residency programs in Turkey. To achieve standardization in allergy training in ORL residency programs, professional associations and authorities should develop solutions in cooperation with legislators

Akut allerjik rinitli hastalarda lokal sempatik sistem disfonksiyonunu gösteren lokal sempatik deri yanıtları testi’nin elektrofizyolojik çalışması

Introduction: In this study, we aimed to investigate sympathetic nervous system functions by local sympathetic skin responses of the nasal septum in patients with acute allergic rhinitis.Material and Methods: Eighty-five patients who were diagnosed as acute allergic rhinitis according to medical history and otorhinolaryngological examination with positive allergy evaluations via skin prick testing and 50 healthy subjects were included to the study. Sympathetic skin responses of the nasal septum were recorded in patients and in the control groups, and sympathetic skin response latencies and amplitudes were compared between groups.Results: The mean value of sympathetic skin response latencies was significantly longer in the patient group than that of the control group (p<0.001). In addition, mean value of sympathetic skin response amplitudes was significantly lower in the patient group than the control group (p<0.001).Conclusion: Our study is the first which electrophysiologically evaluated the local sympathetic nervous functions that shows objective evidence of local sympathetic nervous system dysfunction. This way to access local sympathetic nervous system dysfunction would be helpful in deciding patients' treatment

A 25-Year Bibliometric Analysis of Allergic Rhinitis Publications from Turkey

Objective:To analyze the change over the 25 years period in the number of publications on allergic rhinitis from Turkey, and to compare the data of the four major relevant specialties.Methods:A search was conducted over 25-years between1994 and 2019 using the keywords “allergic rhinitis” and “Turkey” in PubMed®, and “allerji”, “alerji” and “rinit” in TRDizin®. The articles were grouped by specialty; namely, “Otorhinolaryngology (ORL),” “Pediatrics,” adult “Pulmonary disease” and adult “Allergy/immunology,” based on the affiliation of the first author. The total number of publications in each specialty group within the 25-year period were compared using a significance test for a difference in two proportions within the statistical assessment.Results:The 25-year results revealed 624 and 213 publications in the PubMed® and the TRDizin® databases, respectively. When the number of publications in a specific field in both databases was examined, the highest number of publications were identified in the ORL group, followed by the Pediatrics group. The number of publications in the ORL group was statistically higher than those in the “Pulmonary diseases” and “Allergy/immunology” groups in both the PubMed® and the TRDizin® databases (p=0.0001).Conclusion:The analysis of the number of 25-year allergic rhinitis publications from Turkey revealed that the academic interest of otolaryngologists in allergic rhinitis was unaffected, despite the challenges experienced in practice, with an increasing number of publications noted. When the number of 25-year publications was examined, ORL recorded the highest number of publications among all specialties

Evaluation of cornea and anterior chamber results of patients with obstructive sleep apnea syndrome

Objective: To evaluate the anterior segment findings measured via corneal topography of patients with obstructive sleep apnea syndrome (OSAS) and to compare the findings with normal subjects.Methods: A total of 43 eyes from 43 patients with OSAS and 43 eyes from 43 healthy persons who were referred to eye clinics from 2012 to 2016 were randomly selected and included in this retrospective study. Routine eye examination and anterior segment findings measured via corneal topography were recorded for both groups. Central corneal thickness (CCT), keratometry values (K1, K2, and Kmax), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA) of the two groups were compared.Results: The mean CCT values of the control and OSAS groups were 567.23 +/- 31.17 and 544.4 +/- 36.44 (p=0.002), respectively. The mean CV (HR) was found to be 60.51 +/- 8.44 in the control group and 59.78 +/- 3.47 in the OSAS group (p=0.04). There was no statistically significant difference between the OSAS and control groups in terms of mean age, K1, K2, Kmax, ACV, ACD, and ACA (p>0.05). The mean apnea/hypopnea index (AHI) score of the OSAS group was found to be 21.82 +/- 12.79. There was no negative or positive correlation between the AHI score and age, CCT, K1, K2, Km, SCL, SCL, SCA, and CV.Conclusion: Central corneal thickness and CV are lower in OSAS patients than in normal people

Mini clinical evaluation exercise in undergraduate dermatovenereology education: An experience of University of Pamukkale, Medical Faculty

Background and Design: Mini Clinical Evaluation Exercise (Mini-CEX) is being widely used in medical education and is a reliable and valid method for the assessment of residents' competency in medical interviewing, physical examination, humanistic qualities/professionalism, clinical judgment, counseling skills, organization, and efficiency. In order to enhance formative evaluation methods in our faculty, we planned to apply the method to students on dermatovenereology training. Materials and Methods: The Mini-CEX was performed by residents to 42 medical students. At first, 5 residents were evaluated by a faculty member with Mini-CEX and were informed about their application-oriented evaluator roles. The students were informed prior to conducting the assessment. Standard Mini-CEX form was used for the assessment. The participants were rated in 7 competencies and each was rated using a 9-point Likert scale. At the end of each encounter, students and evaluators rated their satisfaction with Mini-CEX using a 9-point Likert scale. Student's t-test and one-way ANOVA were used for statistical analysis. Student feedback was evaluated with "grounded theory". Results: A total of 50 assessments, 44 in outpatient and 6 in inpatient clinic, were performed. Satisfaction with the Mini-CEX was rated by the evaluators and the students as 7,16 and 7,98, respectively. There was no significant difference between the evaluators in terms of student satisfaction. Average time spent on observing the encounter and in giving feedback was 16.5 and 6.5 minutes, respectively. There was no significant difference between assessors in terms of time spent observing and giving feedback. Average scores of assessed clinical competencies were between 4,28 and 8,14. The highest scores were reported on humanistic qualities/ professionalism whereas the lowest were reported on clinical judgment skills. Discussion: According to our data, we believe that Mini-CEX may be used as an assessment tool in medical education. However, further researches should be carried out by different observers for Mini-CEX to be a part of medical education program

Direct Observation of Procedural Skills in Otorhinolaryngology Training

Objective: To assess the experience on using direct observation of procedural skills (DOPS) by trainees and trainers and to evaluate its use during the training process of Otorhinolaryngology (ORL) residency.Methods: This study was designed as a prospective educational research. For the quantitative assessment, the "construct validity" of the assessment tool was examined. For the qualitative assessment, the trainees and trainers’ experiences regarding the use of DOPS in training process were investigated.Results: A total of 55 DOPS assessment forms were filled during the study. The mean observation time was 7.14±4.83 (range: 1-20) minutes, and the mean feedback time was 2.11±2.01 (range: 0.5-10) minutes. A significant difference was detected between the first year trainees and the older ones, whereas no significant difference was observed between the third, fourth, and fifth year trainees. A statistically significant, positive correlation was found between the years of education and the average score. According to the results of the qualitative assessment, the trainees stated that they realized their technical inadequacy in some procedures and it helped them to improve their skills during their residency training. The trainers confirmed that they gave feedback after each assessment. Both the trainers and trainees suggested that specific guidelines should be prepared for every procedure.Conclusion: DOPS is a useful, valid, and fair tool for assessing Otorhinolaryngology trainees. The data obtained from the DOPS forms can be used for demonstrating the success of a training clinic and to evaluate the training program
