(Tubitak Scientific & Technological Research Council Turkey, 2022) Levent, Vecdi Emre; Levent, Vecdi Emre; Cardak, Merve; Aydin, Nizamettin; Bilgisayar Mühendisliği Bölümü
When 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.

(Turkish J Pediatrics, 2024) Sumengen, Aylin Akca; Ismailoglu, Abdul Veli; Ismailoglu, Pelin; Gumus, Terman; Celiker, Alpay; Namlisesli, Deniz; Cakir, Gokce Naz
Background. Understanding the severity of the disease from the parents' perspective can lead to better patient outcomes, improving both the child's health -related quality of life and the family's quality of life. The implementation of 3 -dimensional (3D) modeling technology in care is critical from a translational science perspective. Aim. The purpose of this study is to determine the effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases. Additionally, we aim to identify challenges and potential solutions related to this innovative technology. Methods. The study is a two -group pretest -posttest randomized controlled trial protocol. The sample size is 15 in the experimental group and 15 in the control group. The experimental group's heart models will be made from their own computed tomography (CT) images and printed using a 3D printer. The experimental group will receive surgical simulation and preoperative parent education with their 3D heart model. The control group will receive the same parent education using the standard anatomical model. Both groups will complete the Sociodemographic Information Form, the Surgical Simulation Evaluation Form - Part I -II, and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module. The primary outcome of the research is the average PedsQL Family Impacts Module score. Secondary outcome measurement includes surgical success and patient outcomes. Separate analyses will be conducted for each outcome and compared between the intervention and control groups. Conclusions. Anomalies that can be clearly understood by parents according to the actual size and dimensions of the child's heart will affect the preoperative preparation of the surgical procedure and the recovery rate in the postoperative period.

(Aves, 2022) Harmancı Seren, Arzu Kader; Seren, Arzu Kader Harmanci; Karayurt, Ozgul; Kul, Gulay Aksu; Kilic, Murat; Bozoklar, Cemal Ata; Tokat, Yaman; Hemşirelik Bölümü
Background: The purpose of this study was to evaluate the risk factors affecting psychosocial outcomes of living liver donors after liver transplantations. Methods: This was a descriptive, cross-sectional study. The sample consisted of living liver donors followed by 2 liver transplantation centers in 2 private hospitals in 2 different provinces, between August 2017 and October 2019. All the living liver donors were contacted without a time frame after donation and all the participants were evaluated once. The Beck Depression Scale, SF-36, General Self-Efficacy Scale, and Perceived Available Support Scale were used to collect data. The t-test, Kruskal-Wallis test, Mann-Whitney U-test, and Pearson correlation analysis were used for data analysis. Results: The mean age of the patients was 34.31 +/- 8.22 years. There was a positive, weak correlation between age and physical function. Gender, marital status, financial status, and education levels significantly affected physical components, social function, vitality, depression, and self-efficacy scores. High depression levels negatively affected the physical component, self-efficacy, and social support scores of the living liver donors. High self-efficacy positively affected social support. Conclusion: The study revealed that gender, marital status, employment status, and education levels were associated with psychosocial outcomes. The financial status was the main factor affecting each psychosocial variable. Financial status needs to be assessed in detail before and after the operation.

An Integrated Methodology Proposal for Sustainable Fashion: Understanding and Examining Criteria Affecting the Second-Hand Clothes Shopping
(Gazi Univ, Fac Engineering Architecture, 2022) Usta, Saliha Karadayı; Kadaifci, Cigdem; Endüstri Mühendisliği Bölümü
Sustainable fashion is an important movement that offers numerous benefits in the long run by questioning the actual needs of the consumer, selecting the natural fabrics, preferring the brands providing ethical working conditions for the employees, using the acquired clothes as long as possible, repairing when necessary, and recycling into yarn when the lifetime is over, or transforming into a new product by changing the function of the items. In this context, the most active role of consumers is to prefer quality products that can last for many years and to extend the time of the products remaining in use, especially through the purchase and sale of second-hand clothes. While current papers provide roadmaps based on conceptual details, and consumer perception and attitude, there is no comprehensive study in second-hand shopping practices specific to clothing. Hence, the aim of this study is proposing an integrated methodology to understand the criteria that consumers pay attention in second-hand clothes shopping platforms as a tool that makes sustainable fashion possible via literature review, individual interviews and text mining, to determine the weights of these criteria according to their importance via Step-Wise Weight Assessment Ratio Analysis (SWARA) methodology, and to compare the prominent platform alternatives via Weighted Aggregated Sum Product Assessment (WASPAS) technique. The criteria weights vary depending on the sustainability awareness of consumers, and on the generation gap.

Preparation and Application of Caffeic Acid Imprinted Polymer
(Tubitak Scientific & Technological Research Council Turkey, 2023) Karaman Ersoy, Şeyda; Tutem, Esma; Baskan, Kevser SoeZGEN; Apak, Resat; Temel Eczacılık Bilimleri Bölümü
In the present study, molecularly imprinted polymers were synthesized using caffeic acid (CA) as a template molecule and then used for the extraction of CA and chlorogenic acid (CLA) from complex matrices. Syntheses were carried out in tetrahydrofuran as porogenic solvent using 4-vinyl pyridine, methacrylic acid, acrylamide, and 1-vinyl imidazole as monomers, ethylene glycol dimethacrylate as crosslinker and 2,2'-azobisisobutyronitrile as initiator. In polymerization processes, different ratios of the template:monomer:crosslinker (T:M:CrL) were used to obtain the most suitable polymer. Caffeic acid:4-vinylpiridine:ethylene glycol dimethacrylate's 1:4:16 mole ratio of MIP was determined as the most convenient polymer for CA recognition. In addition, nonimprinted polymers (NIPs) without templates were prepared. Dynamic and static adsorption tests were applied to determine the absorption features of the NIPs and CA-MIPs. Separation and purification studies of CA and CLA were performed with molecular imprinted solid phase extraction (MISPE) application. All steps of MISPE (loading, washing, elution) were optimized by HPLC analysis.

Qualitative and Artificial Intelligence-Based Sentiment Analysis of Turkish Tweets Related To Schizophrenia
(Turkiye Sinir ve Ruh Sagligi dernegi, 2023) Dikeç, Gül; Oban, Volkan; Usta, Mirac Baris; Hemşirelik Bölümü
Objective: 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.

RELATIONSHIP OF DAILY TIME SPENT OUTDOORS WITH SLEEP QUALITY AND EMOTIONAL WELL-BEING AMONG COMMUNITY-DWELLING OLDER ADULTS DURING COVID-19 RESTRICTIONS
(Gunes Kitabevi Ltd Sti, 2021) Karagözoğlu Coşkunsu, Dilber; Balci, Leyla Atas; Cinar, Fadime; Coskunsu, Dilber Karagozoglu; Tanriover, Sezin Hatice; Uluengin, Mehmet Bengu; Fizyoterapi Ve Rehabilitasyon Bölümü
Introduction: Given the recent constraints imposed due to the ongoing COVID-19 pandemic and the importance of the daily light-dark cycle for entraining the human circadian system, it is possible to state that the elderly are likely to be at serious risk of experiencing sleep-related problems. Whilst reduced or limited time outdoors, and thus, exposure to diurnal bright light appear to be detrimental to sleep and emotional well-being in old age, further research is required to confirm this relationship. Materials and Method: To build on earlier work, a two-week study was conducted in a sample of 79 community-dwelling older adults recruited by using snowball sampling method. Throughout the study, the participants were allowed to be outdoors from 10.00 a.m. to 1.00 p.m. on weekdays. Whilst the participants were performing their daily habitual activities, they were asked to keep an activity diary and report on their sleep quality and emotional wellbeing using two questionnaires. Results: The results demonstrated that participants' daily time spent outdoors (49.13 minutes on average) positively correlated with their perceived sleep quality and emotional well-being at various - but significant - levels (p<0.05). Moreover, significant negative correlations were identified between participants' sleep quality and experienced emotional disturbances (p<0.001). Conclusion: Based on the research findings, it is reasonable to conclude that spending momentary periods outdoors may have adverse consequences for the elderly. To maintain a healthy sleep-wake cycle and alleviate related emotional problems in old age, increasing outdoor time and diurnal bright light exposure should be encouraged.
