    A Pilot Study of a Novel Fixation Technique for Fixation of Comminuted Patellar Fractures: Arthroscopic-Controlled Reduction and Circular External Fixation
    (Georg Thieme verlag Kg, 2020) Neyisci, Cagri; Erdem, Yusuf; Kilic, Erden; Arsenishvili, Arsen; Kurklu, Mustafa
    Patella fractures represent for 0.5 to 1.5% of all bony injuries in adults. Open reduction and the modified tension-band technique is the most common surgical technique used for patellar fractures. The purpose of this study is to present the outcomes of 26 comminuted patellar fractures treated with circular external fixator (CEF) under arthroscopic control and discuss its potential advantages over conventional surgical methods. This retrospective study included 26 patients who had closed comminuted patellar fractures and treated by CEF under arthroscopic control between January 2002 and March 2016. All patients treated with this technique were involved to the study as a consecutive series. Patients with noncomminuted transverse fractures were excluded, because they were treated with a different technique. Of the 26 patients 22 were male, 4 were female with the mean age of 33.5 years (range, 16-56 years). Patients were followed for 20 to 28 months (mean, 22 months). The mean time to union and the duration of fixation with the CEF ring was 12 weeks (range, 6-15 weeks). The mean Lysholm's score was 45 (range, 35-58) at the 10th postoperative day, which increased to 51 (range, 40-68) at the end of the first postoperative month and increased to 95 (range, 90-100) 1 month after CEF ring removal. Minor pin tract infection by pin-skin irritation was observed in nine patients. In one patient, refracture occurred due to a fall 19 days after CEF removal. CEF appears to be a safe and effective treatment for comminuted patellar fractures with a high union rate and minimal complications. It is safe and effective, as it allows short hospital stay and avoids a second surgery for removal of the instrument. Early rehabilitation with full weight-bearing promotes rapid recovery and quick return to work. Patients do not have a large unaesthetic scar on the anterior of the knee.

    Remote Rf Laboratory Requirements: Engineers' and Technicians' Perspective
    (Anadolu Univ, 2007) Cagiltay, Nergiz Ercil; Aydin, Elif Uray; Kara, Ali; Department of Electrical & Electronics Engineering; Software Engineering
    This study aims to find out requirements and needs to be fulfilled in developing remote Radio Frequency (RF) laboratory. Remote laboratories are newly emerging solutions for better supporting of e-learning platforms and for increasing their efficiency and effectiveness in technical education. By this way, modern universities aim to provide lifelong learning environments to extend their education for a wider area and support learners anytime and anywhere when they need help. However, as far as the authors concern, there is no study investigating the requirements and needs of remote laboratories in that particular field in the literature. This study is based on electrical engineers' and technicians' perspectives on the requirements of a remote laboratory in RF domain. Its scope covers investigation of the participants' perceptions toward computer mediated communication and it attempts to answer the questions: which studying strategies are preferred by the learners and what kind of RF laboratory content should be provided. The analysis of the results showed that, geographic independence, finding quickly the elements of past communication and temporal independence are declared as the most important advantages of computer-mediated communication. However, reading significant amount of information is a problem of these environments. In the context of how to show the content, respondents want to see shorter text on the screen. Therefore the instructions should include little amount of text and must be supported with figures and interactive elements. The instructional materials developed for such learner groups should support both linear and non-linear instructions. While analyzing the content to be provided, we have seen that, most of the participants do not have access to high level equipments and traditional experiments are considered as the necessary ones for both engineers and technicians.

    How Much Similarity Is Good? the Effect of Similarity and Crowding on Place Satisfaction
    (Routledge Journals, Taylor & Francis Ltd, 2024) Kucukergin, Kemal Gurkan; Koc, Burcu
    The relationship between perceived similarity, crowdedness and tourists' evaluations of their experience has been largely neglected by research into the destination social servicescape. This study therefore examines this relationship to fill the gap in the literature. Data were collected from 282 tourists in Pamukkale, Turkey. PLS-SEM and fsQCA were combined to identify the symmetric and asymmetric effects of the destination social servicescape. The PLS-SEM results showed that demographic similarity significantly increased place satisfaction, whereas psychographic similarity and perceived crowdedness had no effect. The study also used fsQCA to investigate how crowdedness and similarity predict place satisfaction in combination with income, age, education, and gender. The analysis identified five different models of place satisfaction by combining different demographic factors.

    Effects of Cold Therapy on Pain and Anxiety During Needle Removal From Implanted Ports
    (Lippincott Williams & Wilkins, 2023) Bahar, Arzu; Aktas, Demet; Sonmez, Munevver
    This study was conducted as a quasiexperimental, single-blind study to examine the effect of cold therapy on pain and anxiety during port needle removal. Patients in the experimental group received cold therapy 10 minutes before port needle removal. Patients in the control group received no intervention before port needle removal. Data were collected using the visual analog scale (VAS) and State-Trait Anxiety Inventory (STAI). After cold therapy was applied to the patients in the experimental group, the second and third VAS scores were found to be statistically significant and lower than those in the control group (P < .05). There was no statistically significant difference between the anxiety levels of the experimental group and the control group before cold therapy (P> .005). However, the STAI scores of the experimental group were found to be statistically and significantly lower than those of the control group after cold therapy (P < .05). This study determined that cold therapy before port needle removal reduces pain and anxiety. Cold therapy may be recommended as an effective nonpharmacological pain control method with ease of application to prevent pain induced by port needle removal.

    Particle Swarm Optimization of the Spectral and Energy Efficiency of an Scma-Based Heterogeneous Cellular Network
    (Wiley, 2022) Noma-Osaghae, Etinosa; Misra, Sanjay; Ahuja, Ravin; Koyuncu, Murat
    Background The effect of stochastic small base station (SBS) deployment on the energy efficiency (EE) and spectral efficiency (SE) of sparse code multiple access (SCMA)-based heterogeneous cellular networks (HCNs) is still mostly unknown. Aim This research study seeks to provide insight into the interaction between SE and EE in SBS sleep-mode enabled SCMA-based HCNs. Methodology A model that characterizes the energy-spectral-efficiency (ESE) of a two-tier SBS sleep-mode enabled SCMA-based HCN was derived. A multiobjective optimization problem was formulated to maximize the SE and EE of the SCMA-based HCN simultaneously. The multiobjective optimization problem was solved using a proposed weighted sum modified particle swarm optimization algorithm (PSO). A comparison was made between the performance of the proposed weighted sum modified PSO algorithm and the genetic algorithm (GA) and the case where the SCMA-based HCN is unoptimized. Results The Pareto-optimal front generated showed a simultaneous maximization of the SE and EE of the SCMA-based HCN at high traffic levels and a convex front that allows network operators to select the SE-EE tradeoff at low traffic levels flexibly. The proposed PSO algorithm offers a higher SBS density, and a higher SBS transmit power at high traffic levels than at low traffic levels. The unoptimized SCMA-based HCN achieves an 80% lower SE and a 51% lower EE than the proposed PSO optimized SCMA-based HCN. The optimum SE and EE achieved by the SCMA-based HCN using the proposed PSO algorithm or the GA are comparable, but the proposed PSO uses a 51.85% lower SBS density and a 35.96% lower SBS transmit power to achieve the optimal SE and EE at moderate traffic levels. Conclusion In sleep-mode enabled SCMA-based HCNs, network engineers have to decide the balance of SBS density and SBS transmit power that helps achieve the desired SE and EE.

    It is known that the students’ attitudes toward e-learning are an important factor in achieving the targeted learning achievement. The aim of the study was to determine the relationship between attitudes toward e-learning and the academic achievements. This cross-sectional and correlational study was conducted with a total of 135 first-year nursing students. Data were collected via Student Information Form, General Attitudes toward E-Learning Scale, Vital Signs Skills Laboratory Practice Assessment Videos. Two-Way ANOVA, Pearson correlation analysis, multiple linear regression analysis were used to analyze the data. The total mean score of the first-year NSs’ general attitude scale toward e-learning was found to be 52.58±15.93. A statistically negative correlation was found between the “avoidance of e-learning” factor and the NSs’ vital signs skills general achievement scores (r= -0.185; p=.035). Gender (β1= 5.399, p= 0.001), receiving adequate counseling and help on using the e-learning platform (β1= 4.895, p= 0.022) and avoidance of e-learning (β1= -0.222 p= 0.046) explained 20.9% of the variance in vital signs overall achievement score. The results showed that negative attitudes and negative satisfaction with e-learning may lead to a decrease in e-learning academic achievement. © 2023,Turkish Online Journal of Distance Education.All Rights Reserved.

    Career Abandonment Intentions among Software Workers
    (Wiley, 2014) Colomo-Palacios, Ricardo; Casado-Lumbreras, Cristina; Misra, Sanjay; Soto-Acosta, Pedro
    Within the software development industry, human resources have been recognized as one of the most decisive and scarce resources. Today, the retention of skilled IT (information technology) personnel is a major issue for employers and recruiters as well, since IT career abandonment is a common practice and means not only the loss of personnel, knowledge, and skills, but also the loss of business opportunities. This article seeks to discover the main motivations young practitioners abandon the software career. To achieve this objective, two studies were conducted. The first study was qualitative (performed through semistructured interviews) and intended to discover the main variables affecting software career abandonment. The second study was quantitative, consisting of a Web-based survey developed from the output of the first study and administered to a sample of 148 IT practitioners. Results show that work-related, psychological, and emotional variable are the most relevant group of variables explaining IT career abandonment. More specifically, the three most important variables that motivate employees to abandon the career are effort-reward imbalance, perceived workload, and emotional exhaustion. In contrast, variables such as politics and infighting, uncool work, and insufficient resources influence to a lesser extent the decision to leave the career. (c) 2012 Wiley Periodicals, Inc.

    Neural Network and Classification Approach in Identifying Customer Behavior in the Banking Sector: a Case Study of an International Bank
    (Wiley, 2015) Ogwueleka, Francisca Nonyelum; Misra, Sanjay; Colomo-Palacios, Ricardo; Fernandez, Luis
    The customer relationship focus for banks is in development of main competencies and strategies of building strong profitable customer relationships through considering and managing the customer impression, influence on the culture of the bank, satisfactory treatment, and assessment of valued relationship building. Artificial neural networks (ANNs) are used after data segmentation and classification, where the designed model register records into two class sets, that is, the training and testing sets. ANN predicts new customer behavior from previously observed customer behavior after executing the process of learning from existing data. This article proposes an ANN model, which is developed using a six-step procedure. The back-propagation algorithm is used to train the ANN by adjusting its weights to minimize the difference between the current ANN output and the desired output. An evaluation process is conducted to determine whether the ANN has learned how to perform. The training process is halted periodically, and its performance is tested until an acceptable result is obtained. The principles underlying detection software are grounded in classical statistical decision theory.

    The Comparison of Trust Development in Virtual and Face-To Collaborative Learning Groups
    (Anadolu Univ, 2019) Baturay, Meltem Huri; Toker, Sacip
    The study investigates the effect of delivery types of (virtual and face-to-face) collaborative learning environments on the development of trust among group members in a graduate course. For this aim, a quasi-experimental, non-equivalent group comparison was used. It comprised a total of 64 participants 21 in the face-to-face group, and 43 in the virtual group. Study participants were comprised of students registered in a course entitled 'Web-based Education: Principles of Design and Implementation' in the spring semester as part of either a virtual or traditional face-to-face graduate program in Information Systems at an institute of higher education in Turkey in 2010. Trust levels were measured at two different occasions, namely in the beginning and end of the semester, for both study groups. The participants completed a web-based course material design project as a collaborative group activity. The results indicate that trust increases over time among virtual participants, but declines among face-to-face participants. While levels of trust among virtual course participants are lower than those of face-to-face course participants in the beginning of the semester, trust levels of virtual participants surpass those of faceto-face participants by the end of the semester. This study demonstrates that trust can develop in virtual learning environments. The initial level of trust should be taken into consideration by instructors or managers before forming groups.
