AN INVESTIGATION INTO PRE-SERVICE TEACHERS' MOTIVATION TOWARDS RECYCLING BEHAVIORS

The aim of the present study is to analyze pre-service teachers' motivations towards recycling behavior. The survey model was adopted and the sample comprised 157 pre-service teachers studying at various teaching departments of Gazi University. "Motivation towards Recycling Behaviors Scale", developed by the researcher was used as the data collection instrument. The scale which was analyzed with regard to reliability and validity comprises 19 items and four dimensions: internal motivation, external motivation, lack of motivation and social impact. The collected data were analyzed by means of SPSS 18 and LISREL 8.7; t-test, ANOVA and multiple-regression were performed. As a result of the study, it was found out that pre-service teachers' motivation towards the recycling behavior varied between medium and high levels; following environmental magazines and recycling behavior frequency variables are significant determinants of motivation towards recycling behavior, and the variables of recycling behavior frequency and following environmental magazines are significant predictors of recycling behavior.  Article visualizations

The effect of hippophae rhamnoides extract on oral mucositis induced in rats with methotrexate

Objective: To investigate the effect of HRE (Hippophae rhamnoides extract) on oral mucositis induced in rats with MTX. Material and Methods: Experimental animals were divided into groups as healthy (HG), HRE+MTX (HMTX), and control group, which received MTX (MTXC). HMTX group received 50 mg/kg HRE while MTXC and HG groups received equivolume distilled water with gavage once a day. After one hour of HRE and distilled water administration, HMTX and MTXC groups received a single dose of oral MTX 5 mg/ kg. This procedure was repeated for one month. Results: The levels of MDA, IL-1β, and TNF-α were found to be significantly higher in the cheek, lower lip, and tongue tissue of the animals receiving MTX, compared with HG and HMTX groups; however, these parameters were lower in the cheek and low lip tissue, and a milder damage ocurred in these tissues, compared with the tongue tissue in MTXC group. No histopathologic damage was observed in the cheek, lower lip, and tongue tissues of the rats treated with HRE. Conclusion: This findings indicate that HRE as a natural product is an important advantage compared with synthetic drugs for prophylaxis of oral mucositis developed due to MTX

Mathematics learner profiling using behavioral, physiological and self-reporting methods

This exploratory case study aimed at investigating learner profiles when participants are studying, self-reporting, restudying content and answering questions related to the division theorem in mathematics. It includes surveys aiming to measure participants’ epistemological beliefs, metacognitive strategies and the levels of mathematics anxiety; behavioral data including audio-visuals and screen capture embedded with eye-tracking, and physiological data including heart, respiration and eye blink rates. It uses ‘learner profiling framework’ built on previous literature and defined with a new perspective. The data are analyzed using mixed research methodology cross validating self-report, behavioral and physiological data. The results from four participants provide contributions to the literature in four aspects. First, learner profiling framework offers a new methodology to educational research with numerous benefits. Second, CUR (Calculation-Understanding-Reasoning) framework offers a new way of categorizing mathematical cognition and corresponding content. Third, qualitative approach in investigating learner motivations indicates motivational constructs are much more nuanced than previously thought. Fourth, single case approach for studying learner behavior and physiology provides successful links to underlying cognitive and affective processes. The investigations are followed by learner profiles that involve assessments from teacher’s perspective and recommendations for future work

Very late periprosthetic joint infection: etiological agents and outcomes of two stage revision

The main aim of the current study is to evaluate the success of two-stage revision surgery in very late periprosthetic joint infection (PJI). The second aim was to identify the causative etiological agents and to rank these pathogens according to their incidence. Twenty-seven patients (16 THA and 11 TKA) who were operated on with two-stage revision arthroplasty due to very late PJI (>60 months after primary arthroplasty) were included in our study. Demographic information of the patients, operation site, follow-up period, time from the first spacer application to the second stage revision, number of spacer replacement surgeries, duration of infection, presence of fistula, presence of recurrence after second stage arthroplasty and complications were noted. Preoperative and last follow-up Knee Society and Harris Hip Scores were calculated. The success of two-stage revision surgery was evaluated statistically. The causative etiological agents were ranked according to their incidence. The age of the patients at the time of first stage revision ranged from 24 to 94 years, with a mean age of 57.9±15.7. Infection recurrence was 18.75% in the very late hip and 27.3% in the very late knee PJI group. There was a statistically significant increase in postoperative Knee Society and Harris Hip Scores (p [Med-Science 2023; 12(3.000): 700-9

What is the impact of having a family history of migraine on migraine characteristics?

Objectives: There are only a handful of studies examining the clinical differences between patients with and without a family history of migraine. Our aim is to compare the descriptive and clinical properties of patients with and without a family history, and to investigate the association between the migraine burden and disease characteristics and disability of migraine

Effect of Patellar Resurfacing on Clinical Outcomes, Range of Knee Motion and Anterior Knee Pain in Patients with Total Knee Arthroplasty

Objectives: In this study, we retrospectively compare the clinical results, range of knee motion and anterior knee pain in patients on whom we performed knee arthroplasty with and without patellar resurfacing

An investigation of the effects of total hip arthroplasty with femoral shortening in unilateral Crowe type-IV dysplastic hips on sagittal spinopelvic parameters

It has been reported that sagittal spinal alignment may become abnormal in patients with hip osteoarthritis. There is limited data in the literature on how spinopelvic parameters change after total hip arthroplasty (THA) with femoral shortening in unilateral Crowe type IV dysplastic hips. We aimed to investigate the effects of THA with femoral shortening in unilateral Crowe type IV dysplastic hips on sagittal spinopelvic parametres. Patients who underwent THA for Crowe type IV dysplastic hips at our institution between 2014-2019 were included in the study. Pre- and postsurgical standing anteroposterior and lateral spine X-Ray images of the each patient were uploaded to SURGIMAP© (Nemaris Inc.. USA) (https://www.surgimap.com/). The radiographic data of all patients were reviewed and measurements performed for each patient by two senior spinal surgeons. All of the parameters were retrieved from the SURGIMAP© measurement system. There were 18 patients aged 27-60 (mean, 45.5±7.9) years. The mean follow-up duration was 27.5 ± 8.9 (range, 13–42) months. There was no statistically difference between pre-and postoperative values of Sacral Slope (SS), Pelvic incidence (PI) Lumbar Lordosis (LL), PI-LL mismatch and Thoracic Kyphosis (TK), Global Tilt (GT), T1 Pelvic Angle (TPA), Cervical Lordosis (CL) and T1 slope (T1S). We also found no significant change between pre-and postsurgical values of global alignment and proportion (GAP) scores. The only significant change was in detected pre-and postsurgical values of PT, T1Spi, T9Spi ( p = 0.022, p = 0.035, and p = 0.033 respectively). THA with femoral shortening in unilateral Crowe type-IV dysplastic hips does not effect a change in sagittal spinopelvic parameters. Except for PT, T9SPi, and T1SPi do.

Nuss procedure: Technical modifications to ease bending of the support bar and lateral stabilizer placement

Background: Modifications defined to ease bending of the support bar and lateral stabilizer placement during minimal invasive repair of pectus excavatum (MIRPE) have not been reported. We herein report our experience with MIRPE including several technical modifications. Methods: A total of 87 patients who underwent MIRPE were evaluated retrospectively. Technical modifications are (1) a template drawn preoperatively according to the anthropometric measurements, (2) more laterally placed thoracal incisions, (3) single existing incision for multiple support bars, (4) to secure lateral stabilizers to support bar in inverted position. Results: The mean patient age was 11.2 ± 3.8 years. The mean operating time was 63.7 ± 18.7 min. The mean Haller index was 5.4 ± 2.1. Eight patients necessitated two support bars. The support bars were removed in 69 patients after the completion of treatment. Support bars were left in place 26.8 ± 4.3 months. Final chest contours of the 56 patients were evaluated as 12 months passed after support bar removal and excellent repair results were determined in 84.2%. Conclusion: Preoperative bending of the support bar according to anthropometric measurements and fixation of the lateral stabilizers to the support bar in inverted position facilitates bar shaping and lateral stabilizer placement
