The Effect of Instant Stimulation To Kidney 3 Acupuncture Point on DPOAE Responses in Patients With Tinnitus
(Sage Publications inc, 2025) Arslan, Berkay; Tuncer, Sebahattin
Introduction Tinnitus is the perception of sound in the ear or brain in the absence of any external stimulation. Theories regarding tinnitus pathology often involve both cochlear involvement and central regions. Different and alternative medical treatment options have been widely used to help individuals suffering from tinnitus. Objective This study aims to investigate the effect of instant stimulation to the Kidney 3 (KI3) acupuncture point on distortion product otoacoustic emissions (DPOAE) in patients with tinnitus. Material and Method Thirty patients (21 male, 9 female) with subjective tinnitus and normal hearing were included in the study. A total of 39 ears (22 left ears, 17 right ears) were evaluated. After audiological evaluations, the effects of instantaneous stimulation of the bilateral KI3 acupuncture point on DPOAE at frequencies ranging from 1,000 to 6,000 Hz were measured. Results There was a significant difference between amplitudes before and during acupuncture application at all tested frequencies, except at 4,000 Hz in patients with tinnitus in the right ear. There was also a significant difference between amplitudes of before and after acupuncture application at 3,000 and 4,000 Hz in patients with tinnitus in the left ear. Lower amplitude was observed at these frequencies compared with before the application. In patients with bilateral tinnitus, there was a significant amplitude difference between before and during application at 1,000, 2,000, and 3,000 Hz frequencies for the left ear. Conclusion Instant stimulation to the KI3 acupuncture point changed DPOAE amplitude values in patients with tinnitus.
Exploring the Role of Search Experience and Self-Efficacy in Cognitive Self-Esteem: a Latent Growth Modelling Approach
(Sage Publications inc, 2025) Akgun, Mahir; Toker, Sacip
In this study, we seek to contribute to a broader understanding of the processes and contexts that lead to inflated judgments of cognitive ability in human-computer partnerships. We conducted a within-subject experiment design study with 164 college students in order to explore the impact of the search experience on cognitive self-esteem (CSE). Our preliminary findings revealed that search experience is an important factor that influences individuals' perception of their abilities to answer questions. This influence was observed regardless of whether they have access to search tools or not. However, search experience does not explain the significant change in CSE that we found between "access" and "no access" (to search tools) conditions.

Partner Phubbing and Sleep Quality: Serial Mediation Models With Relationship Satisfaction and Perceived Stress
(Sage Publications inc, 2024) Dikdere, Busra; Turkarslan, Kutlu Kagan
The increasing integration of technology into our lives has been affecting our daily routines and even our sleeps. Being a relatively new concept, phubbing refers to the act of overly engaging with one's phone while dismissing those around in the social settings. In this context, partner phubbing involves individuals exhibiting this neglect in the presence of their romantic partners. Evidence suggests that higher partner phubbing may lead to lower relationship satisfaction and higher perceived stress. The aim of the present cross-sectional study was to examine whether relationship satisfaction and perceived stress mediate the relationship between partner phubbing and sleep quality. Four hundred twenty-three individuals (females = 78.5%, M-age = 29.19, SD = 6.87) participated in the study and completed the measures of partner phubbing, relationship satisfaction, perceived stress, and sleep quality. The results of the serial mediation analyses showed that partner phubbing was not a direct predictor of sleep quality. However, the relationship between partner phubbing and sleep quality was mediated by the four indirect paths through relationship satisfaction (beta = 0.04, p < .05), perceived stress (beta = 0.09, p < .05), relationship satisfaction-perceived stress (beta = 0.02, p < .05), and perceived stress-relationship satisfaction (beta = 0.00, p < .05). The findings suggest that partner phubbing may diminish sleep quality by reducing relationship satisfaction and increasing perceived stress levels. Alternatively, perceived stress exacerbated by partner phubbing could reduce relationship satisfaction, which eventually worsens sleep quality. Digital detox programs, group interventions, emotion-focused couple interventions, and stress management training can help overcome the effects of partner phubbing on sleep quality.

Classification of Intermediate and Novice Surgeons' Skill Assessment Through Performance Metrics
(Sage Publications inc, 2019) Topalli, Damla; Cagiltay, Nergiz Ercil
Background. Endoscopic surgeries have become an alternative for open procedures whenever possible. For such types of operations, surgeons are required to gain several skills, whose development needs hands-on practice. Accordingly, gaining these skills today is a challenge for surgical education programs. Despite the development of several technology-enhanced training environments, there are still problems to better integrate these technologies into educational programs. For an appropriate integration, it is critical to assess the skill levels and adapt the training content according to the trainees' requirements. In the literature, there exist several methods for assessing these skill levels. However, there are still problems in practice for objective and repetitive assessment. Methods. The present study aims to estimate the skill levels of participants in surgical training programs in an objective manner by collecting experimental data from residents in an endoscopic surgical simulation environment and gathering performance metrics. Results. It is shown that, by comparing the results of a number of classification algorithms for the best accuracy estimation and feature set, the "novice" and "intermediate" skill levels can be estimated with an accuracy of 86%. Conclusions. The outcomes help surgical educators and instructional system designers to better assess the skill levels of the trainees and guide them accordingly. In addition, objective assessments as highlighted in this study can be beneficial when designing technology-enhanced adaptive learning environments.

The Effect of Training, Used-Hand, and Experience on Endoscopic Surgery Skills in an Educational Computer-Based Simulation Environment (ece) for Endoneurosurgery Training
(Sage Publications inc, 2019) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, Mustafa
Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.

The Immigrant and the Citizen: Out-Group Evaluations and Well-Being of Turkish Immigrants From Bulgaria
(Sage Publications inc, 2021) Korkmaz, Leman; Cingoez-Ulu, Banu; Cingöz-Ulu, Banu
This study examines the postulates of the Rejection Identification Model (RIM) and Rejection Disidentification Model (RDIM) in a sample of 314 ethnic Turks from Bulgaria who migrated to Turkey. We investigate the intervening roles of immigrant and citizen identifications between perceived discrimination and the outcome variables (well-being and out-group evaluations). The results indicate that perceived discrimination predicts negative affect and out-group evaluations. Besides, Turkish citizen identification significantly and positively predicts life satisfaction and satisfaction from living in Turkey, whereas immigrant identification negatively predicts satisfaction in Turkey. Citizen identification predicts positive, and immigrant identification predicts negative out-group evaluations. Immigrant identification plays a mediating role in the link between perceived discrimination and satisfaction in Turkey as well as in that between perceived discrimination and out-group attitudes. The results imply the importance of consideration of contextual factors, including historical and cultural backgrounds, and the meaning of different identities for minority groups in predicting well-being.

An Investigation of Cyberloafing in Relation To Coping Styles and Psychological Symptoms in an Educational Setting
(Sage Publications inc, 2021) Demirtepe-Saygili, Dilek; Metin-Orta, Irem
Cyberloafing, the intentional use of the Internet for personal purposes during class hours, has received the scholars' attention due to the increased access to digital devices in educational settings. Considering the possible negative consequences of misuse of the Internet on health and well-being, the current study aims to investigate the underlying mechanisms of this relationship by examining in detail the role of coping strategies. The sample consisted of 272 undergraduate students. The participants were asked to fill out items measuring cyberloafing behaviors, coping strategies (emotion-focused and problem-focused), and psychological symptoms (depression, anxiety, anger, and somatization). The results revealed that cyberloafing is positively related to psychological symptoms. Furthermore, it is observed that cyberloafing moderates the relationship between emotion-focused coping and psychological symptoms such that at high levels of cyberloafing, emotion-focused coping is associated with higher levels of psychological symptoms. These findings contribute to the existing literature on students' psychological well-being in terms of highlighting its relation with coping strategies and problematic Internet use.

Insights From Pupil Size To Mental Workload of Surgical Residents: Feasibility of an Educational Computer-Based Surgical Simulation Environment (ece) Considering the Hand Condition
(Sage Publications inc, 2018) Dalveren, Gonca Gokce Menekse; Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, Hakan; Menekse Dalveren, Gonca Gokce
The advantage of simulation environments is that they present various insights into real situations, where experimental research opportunities are very limited-for example, in endoscopic surgery. These operations require simultaneous use of both hands. For this reason, surgical residents need to develop several motor skills, such as eye-hand coordination and left-right hand coordination. While performing these tasks, the hand condition (dominant, nondominant, both hands) creates different degrees of mental workload, which can be assessed through mental physiological measures-namely, pupil size. Studies show that pupil size grows in direct proportion to mental workload. However, in the literature, there are very limited studies exploring this workload through the pupil sizes of the surgical residents under different hand conditions. Therefore, in this study, we present a computer-based simulation of a surgical task using eye-tracking technology to better understand the influence of the hand condition on the performance of skill-based surgical tasks in a computer-based simulated environment. The results show that under the both-hand condition, the pupil size of the surgical residents is larger than the one under the dominant and nondominant hand conditions. This indicates that when the computer-simulated surgical task is performed with both hands, it is considered more difficult than in the dominant and nondominant hand conditions. In conclusion, this study shows that pupil size measurements are sufficiently feasible to estimate the mental workload of the participants while performing surgical tasks. The results of this study can be used as a guide by instructional system designers of skill-based training programs.
