Article Citation - WoS: 4Citation - Scopus: 5Qualitative and Artificial Intelligence-Based Sentiment Analysis of Turkish Tweets Related To Schizophrenia(Turkiye Sinir ve Ruh Sagligi dernegi, 2023) Dikec, Gul; Oban, Volkan; Usta, Mirac BarisObjective: The aim of this study was to qualitatively examine Turkish tweets about schizophrenia in respect of stigmatization and discrimination within a one-month period and to conduct emotional analysis using artificial intelligence applications. Method: Using the keyword 'schizophrenia,' Turkish tweets were gathered from the Python Tweepy application between December 19, 2020 and January 18, 2021. Features were extracted using the Bidirectional Encoder Representations from Transformers (BERT) method and artificial neural networks and tweets were classified as positive, neutral, or negative. Approximately 5% of the tweets were qualitatively analyzed, constituting those most frequently liked and retweeted. Results: The study found that, of the total of 3406 schizophrenia-related messages shared in Turkey over a period of one-month, 2996 were original, and were then retweeted a total of 1823 times, and liked by 25,413 people. It was determined that 63.4% of the tweets shared about schizophrenia contained negative emotions, 28.7% were neutral, and 7.71% expressed positive emotions. Within the scope of the qualitative analysis, 145 tweets were examined and classified under four main themes and two sub-themes; namely, news about violent patients, insult (insulting people in interpersonal relationships, insulting people in the news), mockery, and information. Conclusion: The results of this study showed that the Turkish tweets about schizophrenia, which were emotionally analyzed using artificial intelligence were found often to contain negative emotions. It was also seen that Twitter users used the term schizophrenia, not in a medical sense but to insult and make fun of individuals, frequently shared the news that patients were victims or perpetrators of violence, and the messages shared by professional branch organizations or mental health professionals were primarily for conveying information to the public.Article Opinions of Students in the Field of Health on Distance Education During the Covid-19 Pandemic: a Cross-Sectional Study(Galenos Publ House, 2024) Kaya, Gizem; Karaca, Anita; Beji, Nezihe KizilkayaObjective: It is important to determine the opinions and preferences of students about distance education as its use is becoming more and more prevalent because of the Coronavirus disease-19 (COVID-19) pandemic. It was aimed to determine the opinions of students in the field of health about distance education during the COVID-19 pandemic. Methods: This was a cross-sectional, descriptive study which was conducted at the Faculty of Health Sciences of a foundation university in stanbul. The data were obtained from 476 students who were studying at the Faculty of Health Sciences of a university between June and July 2021, using a Student Information Form and Student Opinions on Distance Education Survey. Results: When asked their opinions on distance education, most described that face-to-face education was more useful than distance education (65.1%) and that having practical lessons with distance education negatively affected their learning (61.1%). Conversely, most of the students expressed that they could listen to the parts of the lessons they did not understand again (93.1%), could listen to the lessons they missed (90.3%), and that distance education provided them with the convenience of taking lessons wherever internet access was available (76.7%). Conclusion: The results indicated that students did not have considerable problems during distance education, they benefited from the advantages of distance education and were generally satisfied with it. In relation to the problems experienced during the pandemic, we recommend to take measures especially for applied lessons, to continue to benefit from the advantages of distance education by combining it with formal education in appropriate lessons, and to make necessary improvements by evaluating the opinions of students on a departmental basis.Article Design and Implementation of a Low Cost and Portable Tactile Stimulator Br(Tubitak Scientific & Technological Research Council Turkey, 2022) Kazma, Coskun; Levent, Vecdi Emre; Cardak, Merve; Aydin, NizamettinWhen central nervous system has a problem, somatic area I and II respond to stimulation differently. Therefore, it is possible to identify some of the central nervous diseases when somatosensory on the fingertip is stimulated and responses are recorded and analyzed. We designed a system to stimulate the mechanoreceptors on fingertips. It is composed of a mechanical system for fingertip stimulation, an embedded controller, a control computer, and a software to control overall operation. During test, mechanoreceptors are stimulated according to the test protocols. Individuals' answers are recorded to be evaluated by the developed software. In this study, several design approaches for embedded controller were also examined and an FPGA based controller with the same functionality but higher performance was implemented. A test procedure was performed on 51 individuals at the department of pediatric psychiatry in a hospital, to investigate whether the sex has an effect on attention deficit and hyperactivity disorder.
