Objective: Bruxism is a jaw muscle activity disorder characterized by clenching or grinding of the teeth and can be seen in both children and adults. The purpose of this study is to evaluate the parental knowledge about bruxism in children. Methods: A cross-sectional study was conducted with 265 parents whose children were attended at University of Mersin pediatric dentistry and oral and maxillofacial surgery clinics. Children’s ages varied from 6 months to 16 years old. A 20-questioned questionnaire was used to collect the data. IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) program was used for the analysis. Re . . .sults: A total of 265 parents (159 were female and 106 were male) participated in the study. The majority of the parents were between the ages of 31-40 (60.8%). The rate of clenching and grinding of teeth during sleep (21.5%) was higher than the rate when they were awake (7.2%). The ratio of the parents seeking treatment for their children because of this harmful habit was very low (3.8%). The majortiy of parents (37.7%) reported that they seek help from dentists. The participants believed that bruxism was associated with dental problems (33.6%) and emotional factors (32.8%). A significant difference was found between the educational background of the parents and the ability to define bruxism. Conclusion: Parents had inadequate knowledge about bruxism in children and this was mostly related to the educational background of the parents.

Visible Light Communication (VLC), an alternative to radio frequency (RF), was born as a promising technology. In VLC systems, orthogonal frequency division multiplexing (OFDM) has received much attention due to its high data rate, simple equalization and robustness against inter symbol interference (ISI). However, high peak to average power ratio (PAPR) and LED non-linearity have remarkable effects on the performance of indoor VLC-OFDM systems. Asymmetrically clipped optical OFDM (ACO-OFDM) is a technique that sacrifices spectral efficiency to transmit a unipolar frequency division multiplexed signal over a unipolar channel. In thi . . .s study, fast Walsh Hadamard transform based ACO-OFDM (FWHT-ACO-OFDM) method is proposed to improve the performance of ACO-OFDM system by recovering this spectral efficiency. The performance of the proposed method is verified by computer simulation studies for bit error rate (BER) and PAPR performance criteria. From the simulation consequence, it is seen that the proposed method is better for both performance criteria than ACO-OFDM method Daha fazlası Daha az

In this paper, combining with the fast Walsh Hadamard transform (FWHT) to improve the performance of the double-tree complex wavelet transform (DTCWT) based OFDM technique developed to eliminate the disadvantages of the orthogonal frequency division multiplexing (OFDM) system is suggested. In order to test the achievement of the proposed DTCWT FWHT OFDM method, computer simulation studies are performed in AWGN and flat Rayleigh fading channel environments. In addition, peak to average power ratio (PAPR) simulations, which are one of the major disadvantages of the classical OFDM system, are also realized. From the achieved simulation . . . results, it is seen that the suggested method has better performance than classical OFDM, Discrete Wavelet Transform (DWT) based OFDM and DTCWT OFDM techniques for both performance metrics Daha fazlası Daha az

Objective: Pain, a nonmotor symptom in Parkinson’s disease (PD), affects approximately 40%–85% of patients and adversely affects their daily activities. Therefore, our aim was to establish the validity and reliability of the Turkish version of King’s PD Pain Scale (KPDPS) and to make it available for Turkish patients with PD patients. Methods: The first phase of the study involved the translation and adaptation of the KPDPS to Turkish. For the language validity of the scale, a translation back‑translation method was applied, and expert’s opinion was considered for content validity. In the second stage, the developed Turkish scale wa . . .s administered to 152 patients with PD. In the study, test‑retest was performed in 50 patients for 1 week. Results: The internal consistency value was found as 0.856 in the KPDPS. When the test‑retest was performed, the internal consistency value of the scale showed excellent reliability. The test‑retest‑Cronbach’s alpha value for the whole scale was 0.827. According to the data analysis results, it showed that 14 items on the scale were sufficient for the evaluation of pain in patients with PD. Conclusion: The results from this study show that KPDPS items have adequate internal consistency and test‑retest reliability. The Turkish KPDPS can be used as a reliable and valid instrument for assessing the pain symptoms common to patients with PD Daha fazlası Daha az
