Identification of Anaerobic Gram-Negative Bacilli Isolated from Various Clinical Specimens and Determination of Antibiotic Resistance Profiles with E-Test Methods

The aim of this study was to identify gram-negative anaerobic bacilli isolated from various clinical specimens that were obtained from patients with suspected anaerobic infections and to determine the antibiotic resistance profiles by using the antibiotic concentration gradient method. The study was performed in Afyon Kocatepe University Ahmet Necdet Sezer Research and Practice Hospital, Medical Microbiology Laboratory between 1 November 2014 and 30 October 2015. Two hundred and seventyeight clinical specimens accepted for anaerobic culture were enrolled in the study. All the samples were cultivated anaerobically by using Schaedler agar with 5% defibrinated sheep blood and Schaedler broth. The isolated anaerobic gram-negative bacilli were identified by using both the conventional methods and automated identification system (VITEK 2, bioMerieux, France). Antibiotic susceptibility tests were performed with antibiotic concentration gradient method (E-test, bioMerieux, France); against penicillin G, clindamycin, cefoxitin, metronidazole, moxifloxacin, imipenem, meropenem, ertapenem and doripenem for each isolate. Of the 28 isolated anaerobic gram-negative bacilli; 14 were identified as Bacteroides fragilis group, 9 were Prevotella spp., and 5 were Fusobacterium spp. The highest resistance rate was found against penicillin (78.5%) and resistance rates against clindamycin and cefoxitin were found as 17.8% and 21.4%, respectively. No resistance was found against metronidazole, moxifloxacin, imipenem, meropenem, ertapenem and doripenem. As a result, isolation and identification of anaerobic bacteria are difficult, time-consuming and more expensive when compared with the cost of aerobic culture. The rate of anaerobic bacteria isolation may be increased by obtaining the appropriate clinical specimen and appropriate transportation of these specimens. We believe that the data obtained from the study in our center may offer benefits for the follow up and treatment of infections caused by anaerobic bacteria and may contribute to the current literature. Because of high resistance rate detected against penicillin, this antibiotic should not be used as a first choice in empirical treatment. Cefoxitin may be used in empirical antimicrobial treatment of anaerobic gram-negatives; but the rate of antibiotic resistance should be detected for more useful and proper treatment. The prior selection of the most effective antibiotic, may contribute to decrease the rate of high resistance. In our study, no resistance was observed against carbapenem group antibiotics and metronidazole; so these antibiotics should be reserved as treatment options in the future for infections caused by resistant gram-negative anaerobic bacteria.

An application of fuzzy VIKOR method on evaluation of the university students' preferences on selected Turkish banks

We proposed a fuzzy multiple criteria decision making (MCDM) approach for the preferences of university students in Afyon Kocatepe University over the service quality of selected banks. This research first examined the literature and service quality (SERVQUAL) criteria for the banks. Then, we demonstrated the notation steps of fuzzy VIKOR. A questionnaire consisting of linguistic variables was prepared and applied to almost 400 students and some experts to collect the preferences over service quality. We refrained from asking quantitative numbers in the questionnaire since it is difficult to assess the quality with concrete values. This paper focused only on the applicability of fuzzy MCDM methods over banking service quality. We do not aim to rank the banks and gave them advice though we aimed to show the applicability the methods with linguistic variables. The empirical study analysed four banks and findings are shown in the conclusion section.

The teaching was realized through traditionally laboratory method with the control group, whereas through Vee-diagrams with the experimental group. Pre-service science teachers constructed Vee diagrams for presenting their experiment reports during whole laboratory process. The data were gathered through “Achievement Test (AT)” and “Attitude Scale for Science Laboratory (ASSL)”. The findings indicated that although there is no significant difference (p>.05) between the pre-test achievement scores of groups, the result of the post-test exhibited that there is a significant difference among groups, whichis favor of the experiment group (p<.05). The findings also indicated that there was no a significant difference between posttest attitude scores of the experimental group and control experimental group (p>.05).Keywords: Vee diagram, achievement, attitude.

Examining the Relationship between Pre-Service Teachers’ Critical Thinking Disposition, Problem Solving Skills and Teacher Self-Efficacy

The aim of this study was to examine the relationships between the pre-service teachers’ critical thinking disposition, problem-solving skills and self-efficacy beliefs. The participants of the study were 519 pre-service teachers from Afyon Kocatepe University, Education Faculty. Critical Thinking Disposition, Problem Solving Inventory, and Teacher Self-efficacy Scale were used to collect the data. Arithmetic mean, Pearson Product-Moment Correlation Coefficient and Multiple Linear Regression Analysis were employed in data analysis. The results of the study revealed that the pre-service teachers’ critical thinking disposition was low, problem-solving skills were moderate and teacher self-efficacy perceptions were quite adequate. However, the critical thinking disposition and problem-solving skills revealed significant positive correlations with all dimensions of teacher self-efficacy. An important finding is that critical thinking disposition and problem-solving skills were positive and significant predictors of all sub-dimensions of teacher self-efficacy beliefs.

Sizing, design, and installation of an isolated wind–photovoltaic hybrid power system with battery storage for laboratory general illumination in Afyonkarahisar, Turkey

power generation system of a size able to meet the electric power requirement for general illumination of the electric laboratory at Afyon Kocatepe University was dimensioned and installed. While determining the installation power of the hybrid wind–solar power generation system, the regional wind–solar energy potential and the magnitude of demanded power were the most important factors. It was decided to supply 400 W of the total 500 W of electric power required by the lamp group used for illumination of the electric laboratory from solar panels and 100 W from a wind turbine according to the wind–solar energy potential of the region and the cost analysis. For the hybrid energy-generation system that was designed and installed, by considering the data for the annual mean sunshine period and wind speed, the most suitable system components and thus the installation cost were determined. The electric power generated by the hybrid wind–solar power generation system and the electric power consumed by the laboratory illumination elements supplied with this system during one year were compared. According to the 12-month measurement results for power generation and consumption in the installed system, it was observed that the generated electric power was higher than the consumed electric power. Consequently, by not paying the total electric bill for electric power consumed by the general illumination elements, use of it for other education expenses was made possible. Besides, the installation costs in Turkey were compared with those in the countries of Denmark, Germany, Spain, and Portugal, where two important components of the dimensioned and installed hybrid wind–solar power generation system – wind and solar energy – are used effectively.

Evaluation of professional awareness in physiotherapy and rehabilitation students of Afyon Kocatepe University

In latest years, physiotherapists have been progressively interested in defining their professional identity. For this purpose, Physiotherapy and Rehabilitation Departments of universities in Turkey lecture courses about this profession. The students have the opportunity to improve their professional awareness in these courses. The aim of this research is to determine the professional awareness of the students of the Department of Physiotherapy and Rehabilitation at Afyon Kocatepe University. In the present study, “Professional Awareness Questionnaire” was applied to 227 students who is the first, second, third and fourth grade students at Afyon Kocatepe University. According to this study, the most correctly answered question was related to type of grade point for placement the department (95.2%). Interns respond more questions correctly (p 0.05). In conclusion, the findings from this study show that professional awareness can be influenced by individual differences. However, the level of professional awareness and the interest in the profession of the student can be increased by professional courses.

Evaluation of Low Back and Neck Pain and Disability of Interns at Physiotherapy and Rehabilitation Department of Afyon Kocatepe University

Repetitive tasks, high force, direct pressure, and awkward joint and prolonged constrained posture are cited as prime risk factors, making particularly younger adult physiotherapists vulnerable to musculoskeletal injury. Fourth-grade students (interns) perform clinical practice at Afyon Kocatepe University Hospital. They apply hydrotherapy, electrotherapy, robotic therapy, virtual reality therapy and exercise therapy to patients (inpatient and outpatient) at both orthopaedic and neurology units approximately twelve months. Because we think they are under the risk of low back and neck disorders therefore aim of the present study is to evaluate recent low back and neck pain and disability of them. 50.6% participants had recent low back pain; 52.9% participants reported mild and moderate low back disability. 21.8% participants had recent neck pain; 16% participants showed mild, moderate and severe neck disability. The difference between units related to low back and neck pain or disability wasn’t significant statistically (p>0.05). Most participants announced that they used the body biomechanics correctly (84.1%) and took care of ergonomic conditions (91.5%). In conclusion, it is vital to identify prevalence of low back and neck pain among physiotherapy students and take necessary precautions to prevent further problems.

Effect of Increased Neutrophil-to-Lymphocyte Ratio (NLR) and Decreased Mean Platelet Volume (MPV) Values on Inflammation in Acute Mania.

The neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) are simple, low-cost, and useful inflammatory markers detected in routine complete blood count (CBC), and their use has recently become widespread. In this study, we aimed to investigate the presence of an inflammatory state in manic patients on the basis of NLR and MPV values. This retrospective study was performed on 76 patients with acute mania who were admitted to the Inpatients Psychiatry Clinic of Afyon Kocatepe University Hospital in Turkey. Diagnoses were based on Diagnostic and Statistical Manuel of Mental disorder (DSM-IV). The control group consisted of 74 healthy individuals recruited from the community. They were age- and sex-matched with the study group. NLR values of the manic patient group were 2.2±1.4 and those of the control group were 1.6±0.5. NLR values were significantly higher (p=0.004) and MPV values were significantly lower in the manic patient group than in the control group (10.0±1.2 vs. 10.9±2.3, p=0.027). Increased NLR and decreased MPV levels may reflect inflammation in manic patients, and inflammation may play a role in the complex pathophysiology of acute mania.

Values Education from Perspectives of Classroom Teachers

Values education is a process, which begins at home and continues in society and in formal education institutions. The purpose of this research is to determine the opinions of primary school teachers about values education in primary schools. In the current research, the qualitative research method and focus group interview technique were used. The participants of the study were eight classroom teachers who were pursuing master’s degree at the classroom education program of Afyon Kocatepe University. The participants were selected using the intense case sampling, which is part of purposeful sampling technique. The data were collected through audio-taped group interview. The credibility of this study was enhanced by expert review. The interview schedule was sent to experts for review. The trustworthiness of this study was established by the formula proposed by Miles and Huberman. It was calculated as 0.92. The data collected from the interview were examined using a qualitative data analysis approach. The findings of the study showed that if value education starts at early ages it would provide much more opportunity to prepare for future life, to improve personality and to have long-lasting values. The participants argued that parents are very significant in value education. The participants suggested that value education should be either an independent course or certain values should be taught in existing courses. They also proposed that in value education case studies and drama can be used and that positive and desired behaviours and empathy should be encouraged among children.

The effect of informing mothers on level of anxiety in day surgery of children


 
 
 Abstract
 Objective:The aim of the study is to examine the effect of informing mothers before operations on the level of anxiety in day surgeries of children.Materials and Methods: The study was an intervention type and was carried out in the departments of otolaryngology and pediatric surgery in Eskisehir Osmangazi University Medical Faculty Hospital and in the department of pediatric surgery in Afyon Kocatepe University Medical Faculty Hospital. A total of 100 mothers, 50 of whom were control group and the other 50 were case group, were sampled randomly. The data were collected via the “Family and Child Introductory Information Form” and the State-Trait Anxiety Inventory (STAI) which was developed by Spielberger et al.(1966) and translated and adapted into Turkish by Oner and Lecompte (1983). The data were evaluated via the IBM SPSS 13.00 statistical packaged software. The Analysis of Variance, Chi-Square, Student’s t-test and Posthoc Turkey HSD were used to carry out analyses.Results:The groups’ average STAI scores were compared before the surgery. The average SAI score of the control group before the surgery was 46.34±4.20, and that of the case group was 41.72±4.14. Therefore, there was a significant difference between the two groups (p< 0.05). When the average TAI scores before the surgery were compared, it was found that the average TAI score of the control group was 43.44±4.14 and that of the case group was 41.98±4.34. Therefore, there was no difference between the two groups (p> 0.05).The groups’ average STAI scores were compared after the surgery. The average SAI score of the control group after the surgery was 42.08±5.60, and that of the case group was 40.10±4.16. Therefore, there was no difference between the two groups (p> 0.05). When the average TAI scores before the surgery were compared, it was found that the average TAI score of the control group was 42.32±4.12 and that of the case group was 41.20±5.06. Therefore, there was no difference between the two groups (p> 0.05).Conclusion and Recommendations: It was found that the anxiety levels of the mothers of children who visited the hospital to undergo an ambulatory day surgery was high; however, it was also found that the informing made before the surgery had a positive effect on decreasing the anxiety. Therefore, it should not be forgotten that the nursing care and informing done in accordance with ethical principles have a major contribution to nurses’ professionalization and self-realization.

Pre-Service Teachers' Concept Images on Fractal Dimension

The analysis of pre-service teachers' concept images can provide information about their mental schema of fractal dimension. There is limited research on students' understanding of fractal and fractal dimension. Therefore, this study aimed to investigate the pre-service teachers' understandings of fractal dimension based on concept image. The descriptive method was used in this study. The sample under investigation comprised of 78 (26 males and 52 females) freshmen pre-service elementary mathematics teachers at Afyon Kocatepe University in Turkey. Data was collected by an open-ended questionnaire and clinical interview. The questionnaire was developed by the researcher based on previous studies in the areas of teaching and learning fractals. Data was categorized by semantic content analysis and analyzed using descriptive methods. Analyzing the data gathered from clinical interviews, themes determined in the questionnaire were taken into consideration. The findings showed that pre-service teachers had difficulty in understanding fractal dimension and in making sense of it. Moreover, pre-service teachers could calculate fractal dimension, but they were not aware of what was being calculated completely.

The effect of sleep apnea severity on cardiac autonomic activity during night time in obstructive sleep apnea patients

ABSTRACT CONTEXT AND OBJECTIVE: Impaired autonomic cardiac function is an important consequence of obstructive sleep apnea (OSA). This impairment is mainly due to intermittent hypoxia episodes following apneas. However, the impact of apnea severity on autonomic cardiac function remains unclear. The aim of this study was to evaluate the relationship between the severity of sleep apnea and heart rate turbulence (HRT) and heart rate variability (HRV) in OSA. DESIGN AND SETTING: Observational cross-sectional study conducted in the Departments of Cardiology and Pulmonary Diseases, Afyon Kocatepe University, Turkey. METHODS: 106 patients with OSA and 27 healthy volunteers were enrolled. Based on apnea hypopnea index (AHI) values, obstructive sleep apnea severity was classified as follows: mild OSA (AHI ≥ 5 and < 15), moderate OSA (AHI ≥ 15 and ≤ 30) and severe OSA (AHI > 30). HRV and HRT parameters were assessed via 24-hour digital Holter electrocardiogram recordings for all subjects. RESULTS: HRV and HRT results were significantly lower among OSA patients than among control subjects (P < 0.05). However, there were no significant differences in HRT and HRV between the three patient subgroups. Correlations did emerge between AHI and the NN-interval parameter RMSSD and between oxygen desaturation and turbulence slope (respectively: r = -0.22, P = 0.037; and r = -0.28, P = 0.025). CONCLUSION: HRT and HRV results deteriorate in OSA. Correlations between apnea severity and these parameters seem to be present.
