Öğe Synchronization Analysis of a Master-Slave BEC System via Active Control(GAZI UNIV., 2023-02-18) Tosyalı, Eren; Aydoğmuş, FatmaThis paper will focus on theoretical treatment of the dynamic of the Bose-Einstein Condensate (BEC) systems contained different external trapping potentials. We construct the phase space diagrams and Lyapunov Characteristic Exponents (LCEs) for master and slave systems depended on the system parameters and propose a nonlinear control for the synchronization of systems in their chaotic states. The synchronization is obtained in master-slave scheme for different initial values. Numerical results are also given to show the efficiency of the used control technique.Öğe Effects of nutrition and exercise habits in patients with type 2 diabetes(European Journal of Therapeutics, 2018) Duymaz, TomrisABSTRACT: Objective: Diet and exercise therapy form the basis of treatment of type 2 diabetes mellitus (T2DM). The objective of the present study was to evaluate the effects of diet and physical activity interventions for patients with T2DM. Methods: We assessed the prospective association between levels of physical activity, diet, and quality of life (QOL) in patients with T2DM. We measured body mass index (BMI), waist-to-hip ratio, and QOL index (36-item Short Form Health Survey). A total of 300 patients (169 women and 131 men) were enrolled in the study. Results: The mean age and BMI of the patients were 53.50±8.58 years, 30.39±3.97 kg/m2 in women and 56.32±8.80 years, 30.28±1.79 kg/m2 in men, respectively. QOL was significantly increased in patients with T2DM with regular exercise and diet (p=0.001, 0.024, and 0.012). Conclusion: Our findings show that combined diet and physical activity interventions achieved clinically meaningful increase in the QOL. Especially, aerobic exercise program improved the QOL in women with T2DM.Öğe Use of mirror therapy to treat psychogenic tremors(European Journal of Therapeutics, 2018) Duymaz, TomrisABSTRACT: Psychogenic tremors present with various clinical demonstrations in neurological practice. In mirror therapy, the patient concentrates on the image of the normal limb and learns to manage pain and movement. This study aimed to use mirror therapy for the treatment of psychogenic tremors. A 19-year-old female presented in the hospital with complaints of incompetence in manual skills, sluggish movements, reduction in muscle strength, weakness of fine motor activities, and presence of involuntary movements, such as tremors in the right upper extremity, which appeared approximately 2 years ago but worsened in the last 1 year. Both before and after treatment, we used a digital goniometer to assess the range of motion of the forearm and wrist, digital hand-held dynamometer to evaluate flexor and extensor muscles of the hand and wrist, hand grip dynamometer and pinchmeter to evaluate muscle strength, Disabilities of the Arm, Shoulder and Hand (DASH)questionnaire to assess the functional capacity of the upper extremity, Jebsen hand function test to evaluate the functionality of the hand, Grooved Pegboard test to evaluate manipulative skills, and functional independence measure (WeeFIM) to evaluate the quality of life. There was an improvement in all the parameters when compared before and after treatment. The results of this study showed that mirror therapy was a very useful approach in the treatment of psychogenic tremors, which significantly disrupt exercise compliance and are characterized by severe psychogenic tremors that reduce the quality of life.Öğe Use of creative activities in physiotherapy and rehabilitation(European Journal of Therapeutics, 2018) Duymaz, TomrisABSTRACT: Objective: A survey was performed to study the use of creativity in the field of physiotherapy and rehabilitation. There has been little research on this topic in Turkey and only a few studies are reported to have used music therapy for children. Therefore, the present study aimed to perform a similar survey as conducted in Sweden. Methods: In this study, we sent a survey to physiotherapists in İstanbul via email. Recorded data included sociodemographic characteristics (gender, age, and education) of the physiotherapists; where and how long they had been working; the specialties of the physicians that they work with; whether they continued training/education after graduation, and if so how did they maintain their studies; whether/how often they involve creative activities in the treatment sessions; which activities they prefer; whether they get any negative reaction from patients or colleagues while applying the creative activities; and whether they apply any treatment method other than conventional methods. Results: According to the results of the study, 59% of the physiotherapists benefit from using creative activities during their sessions. While 21% of them use handcrafts, 19% make use of computer games, 8% take advantage of music/theater activities, 6% use exercise painting, and 2% use practice gardening. Conclusion: There has been no previous study on this topic in Turkey, this study provides insight into existing practices and may encourage further use of creative methods in therapy. Further studies should expand on the experience of physiotherapists concerning the benefits of creative activities.Öğe Hekim ve hastanenin cerrahi robot kullanımının hastaya verdiği zarardan sorumluluğu(Selçuk Üniversitesi Hukuk Fakültesi Dergisi, 2021) Aktaş, Nihan KoyuncuÖZET: Tıbbi robotların bir alt türü olan cerrahi robotların kullanımı yabancı ülkelerin yanı sıra ülkemizde de giderek yaygınlaşmaktadır. Ancak günümüz uygulamasında cerrahi robotlar kendi kendine öğrenen, öğrendikleri neticesinde yeni kararlar veren veya cerrahi müdahaleyi tamamen bağımsız olarak yürütebilen seviyeye henüz ulaşmamıştır. Örneğin cerrahi robotların en başarılı ve yaygın örneği olan da Vinci cerrahi robot tamamı ile hekimin kontrolünde ve hekimin komutları ile hareket etmektedir. Bunun yanı sıra ROBODOC gibi yine kendi kendine öğrenemeyen; ancak sınırlı da olsa bağımsızlığı olan robotlardan da faydalanılmaktadır. Cerrahi robotların sağlık hizmetine dahil edilmesi ile beraber hekim ve hastanenin robotik cerrahiye bağlı olarak hastaya verilen zarardan sorumluluğunun tartışılması gerekmektedir. Bu tartışma, cerrahi robotun otonomi derecesine bağlı olarak şekillenir. Bu çalışmada hekim ve hastanenin sorumluluğu, robotun otonomi derecesine bağlı olarak özellikle TBK md. 116 hükmü kapsamında değerlendirilmiştir.Öğe Turkish version study of Parkinson’s disease quality of life questionnaire (PDQL)(Nöropsikiyatri Arşivi, 2015) Çakmak, Aycan; Dereli, Elif ElçinABSTRACT: Introduction: This study aimed to evaluate Turkish transcultural adaptation, reliability, and validity of “Parkinson’s Disease Quality of Life Questionnaire” (PDQL), which has been developed to assess the quality of life of patients with Parkinson’s disease. Methods: Eighty-nine patients who were included in the study were diagnosed with Parkinson’s disease. They were presented to the outpatient clinic of the Istanbul Faculty of Medicine, Physical Medicine and Rehabilitation department between July 2005 and April 2008. The Turkish translated version of PDQL (PDQL-TR), “Unified Parkinson’s Disease Rating Scale” (UPDRS), and Hoehn & Yahr (HY) were used as the main outcome measures. Results: The calculated Pearson correlation coefficient for PDQL, H&Y, and UPDRS ranged between ?0.36 and ?0.80. Cronbach’s alpha coefficients of the PDQL-TR complete questionnaire and subdomains were higher than 0.80. The absolute value of item-total score correlation coefficients by Pearson fluctuated between 0.40 (question 4-total score) and 0.88 (question 26-total score), whereas the subdomain-total score correlation coefficients ranged between 0.81 and 0.96. PDQL-TR showed high stability according to the ICC results, ranging between 0.75 (Emotional Function) and 0.88 (Parkinsonian Symptoms). Conclusion: The psychometric features of PDQL-TR are satisfactory, and our results are consistent with the previous literature findings. PDQLTR is a valid and reliable tool to measure health-related quality of life in patients with Parkinson’s disease.Öğe Clinical pulmonary infection score (CPIS) as a screening tool in ventilatory associated pneumonia (VAP)(KARE PUBL, 2017) Başyiğit, SelmaObjective: Ventilator-associated pneumonia (VAP) is one of the leading nosocomial infections in intensive care units (ICUs), causing high mortality and increased health care costs. It is known that early diagnosis and treatment reduces mortality and morbidity. In this study, we aimed to assess the efficacy of Clinical Pulmonary Infection Score (CPIS) in early diagnosis in VAP. Material and Methods: The study was performed on 43 cases. Clinical Pulmonary Infection Score parameters of each patient; body temperature, leukocyte count and morphology, volume and character of tracheal secretions, arterial oxygenation, pulmonary infiltration on chest X-ray, progression of pulmonary infiltration, microbiological culture results were recorded. Clinical Pulmonary Infection Scores were calculated at admission using the first five parameters of CPIS (basal CPIS) and after 48 hours following intubation, using seven parameters with the tracheal aspirate (TA) culture results. The patients were followed with CPIS calculated during the mechanical ventilation and with tracheal aspirate (TA) cultures obtained every three days. The patients were grouped as VAP (+) and VAP (-) in accordance with the obtained data. Results: Basal CPIS levels were similar between the two groups (p>0.05), while significant differences were detected between the 48th hour and 5th day CPIS (p<0.01). There was difference between the pre-diagnosed CPIS levels of VAP (+) and VAP (-) cases (p<0.01). Conclusion: Serial CPIS measurements can help the clinician in early diagnosis and treatment of VAP.Öğe Addiction Profile Index-Family (BAPY-A): The Study of Validity and Reliability(KLINIK PSIKIYATRI DERGISI, 2017) Ögel, Kültegin; Çelikay, Hande; Başabak, AslıObjectives: Addiction is a disease that affects the family and also requires family's participation on treatment. Therefore, determination of the family property will contribute to organize the treatment. Method: Addiction Profile Index-Family (BAPi-A) was developed as a scale consisting of 10 questions to asess family's abilities to set rules, give responsibility, resolve conflict, family bond and the attitude of the family towards the addict. BAPi-A developed on practiced with parents, spouces and their relatives of addicts applied the Addiction Clinic and Family Assessment Device (ADO) were applied. The application was repeated after 15 days. Results: Cronbach Alpha coefficient of the scale was found as 0.82. 4 factors explained %30.81 of the total variance were obtained on explanatory factor analysis. These factors were named "establish relationship", "family bonds" and "attitude towards the addict". A correlation of 0.52 (p<0.01) was found between the average total scores of ADO and BAPi-A. The correlation of between pre-test and post-test of BAPi-A was found 0.67 (o<0.01). When comparing the scale scores of families that have an addict member and not, the variance between average total scores was found statistically significant. And also similar findings were obtained when parents, spouces and other relatives were evaluated. Conclusion: Thus, the Addiction Profile Index-Family (BAPi-A) can be used as a valid and reliable instrument to asses family's abilities to set rules, give responsibility, resolve conflict, and establish relationship, family bonds and the attitude towards the addict.Öğe Common Behaviors of Spinor-Type Instantons in 2D Thirring and 4D Gursey Fermionic Models(Hindawi Ltd, 2014) Tosyalı, Eren; Aydoğmuş, FatmaWe investigate two examples of conformal invariant pure spinor fermionic models, which admit particle-like solutions of the classical field equations. For different dimensions and quantum spinor numbers, the vector field visualizations of the models are constructed to provide a better understanding of the spinor-type instanton dynamics in phase space. The hierarchical cluster analysis method investigations of the models are also presented. Finally, the autocorrelation and power spectrum graphs of models are constructed and frequencies of motions are defined.Öğe Gait speed and related factors in Parkinson's disease(Soc Physical Therapy Science, 2015-12) Demircioğlu, Demet Tekdöş[Purpose] The aim of this study was to investigate the relationship between gait speed and various factors in ambulatory patients with idiopathic Parkinson's disease. [Subjects] Fifty ambulatory patients with idiopathic Parkinson's disease who were admitted to an outpatient clinic were included in this cross-sectional study. [Methods] The Hoehn and Yahr Scale was used for measurement of the disease severity. Gait speed was measured by the 10-Meter Walk Test. Mobility status was assessed by Timed Up and Go Test. The Hospital Anxiety and Depression Scale was used for evaluation of emotional state. Cognitive status was examined with the Mini-Mental State Examination. The Downton Index was used for fall risk assessment. Balance was evaluated with the Berg Balance Scale. Comorbidity was measured with the Cumulative Illness Rating Scale. The 36-Item Short Form Health Survey was completed for measurement of quality of life. [Results] The mean age was 66.7 (47-83) years. Twenty-eight (56%) patients were men. Gait speed was correlated positively with height, male gender, Mini-Mental Examination score, Berg Balance Scale score and physical summary scores of the 36-Item Short Form Health Survey. On the other hand, there was a negative correlation between gait speed and age, disease severity, TUG time, Downton Index, fear of falling, previous falls and the anxiety and depression scores of the Hospital Anxiety and Depression Scale. There was no correlation between gait speed and comorbidity. [Conclusion] The factors related with the slower gait speed are, elder age, clinically advanced disease, poor mobility, fear of falling, falling history, higher falling risk, and mood disorder.Öğe Master-slave synchronization of Bose-Einstein condensate in 1D tilted bichromatical optical lattice(INST Condensed Matter Physics NATL ACAD Sciences Ukranie, 2020) Tosyalı, Eren; Aydoğmuş, FatmaThis paper investigates the synchronization of chaotic behavior in a model of Bose-Einstein condensate (BEC) held in a 1D tilted bichromatical optical lattice potential by using the active control technique. The synchronization is presented in the master-slave configuration which implies that the master system evolves freely and drives the dynamics of the slave system. Also the numerical simulations are given to indicate the practicability and the effectiveness of the used controllers.
