Article Citation - Scopus: 3The Effects of Maternal Omega-3 Fatty Acid Supplementation on Breast Milk Fatty Acid Composition(İstanbul Medipol University, 2018) Ay, E.; Büyükuslu, N.; Batırel, S.; İlktaç, H.Y.; Garipağaoğlu, M.Breast milk is the first source of omega-3 fatty acids (FA) for infants. We hypothesized that maternal omega-3 FAs supplementation affects the FA composition of breast milk. Thirtysix women received 950 mg omega-3 polyunsaturated (PUFA) supplementation per day for 9 months from 22-24 weeks of pregnancy until the 6 months of lactation and 26 women were enrolled as controls. Demographic data and nutritional status were taken by a questionnaire. Breast milk samples were collected at just after birth and 6 months of lactation. Fatty acids were analyzed by gas chromatography mass spectrometry (GC-MS). Data was assessed using SPSS 22.0 software. The supplementation increased the level of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) while decreased the level of saturated fatty acids (SFA) in breast milk. The ratio of omega-6/omega-3 FAs was also decreased in the supplemented mothers’ milk. In conclusion the maternal supplementation of omega-3 FAs improved the DHA and EPA levels. © 2018, İstanbul Medipol University.

Female are at greater risk of developing anemia than men, yet scarce data exist on anemia associated outcomes in female dancers. The aim of the present study was to investigate the relationships between bilateral isokinetic knee extensor and flexor muscles strength, and biochemical hematologic parameters in female modern dancers. Concentric isokinetic peak torque [(PT)-N.m], peak torque % body weight [(PT% BW)-N.m.kg(-1)], average peak torque [(AVGPT)-N.m] and total work [(TW)-J)] of the knee extensor and flexor muscles were measured at a velocity of 60 degrees, 180 degrees and 300 degrees s(-1). To determine hematological parameters [red blood cell count (RBC), hematocrit (Hct), and Hb] were determined. The dancers of LHG and HHG had significant differences (p <= 0.05) for hematological parameters. HHG dancers' strength production in extensors muscles of PT, TW and AVGPT in non-dominant left leg (p <= 0.05) were significantly higher than LHG dancers. There were significant (p <= 0.05) negative correlations between TW (300 degrees s(-1)) of left leg extensor muscles and RBC, Hct and Hb variables. Isokinetic knee muscular strength is associated with hematologic variables in female modern dancers. The current study provides evidence that the low-level hematologic parameters has decreased performance on torque production of extensors knee muscles in non-dominant leg during isokinetic muscle strength endurance in female modern dancers.Book Part Marketing Ethics and Ethical Issues Related To Marketing Communication(Springer-verlag Singapore Pte Ltd, 2018) Sayil, Emine Mediha[No Abstract Available]Article Citation - WoS: 2Citation - Scopus: 3Identification Problem of a Leading Coefficient To the Time Derivative of Parabolic Equation With Nonlocal Boundary Conditions(Springer international Publishing Ag, 2019) Kanca, Fatma; Mishra, Vishnu NarayanIn this study, the problem of determining the time-dependent leading coefficient to the time derivative of heat equation with nonlocal boundary and integral addition conditions is considered.

Unlike previous studies, this research extends the literature by analysing affective as well as cognitive dimensions in the same model with a holistic view by simultaneously examining the direct and indirect effects of the related concepts. The distinctive nature of this study is its evaluation of customer satisfaction and loyalty from the perspective of actual consumers. The research model was tested using data collected from 685 retail banking customers by applying structural equation modelling. The findings show that relationship marketing induces loyalty through relationship quality, customer value, and satisfaction, which are mainly provided by trust, communication, and relationship investment. Furthermore, relationship investment and relationship quality are the most important factors in the development of customer value, satisfaction, and loyalty. The emotional value dimension, which captures the affective aspects of perceived value, has the strongest effect on both satisfaction and loyalty.Article Citation - WoS: 4Citation - Scopus: 6A Systematic Approach for Improving the Software Management Process(World Scientific Publ Co Pte Ltd, 2019) Birgun, Semra; Cerkezoglu, Burcu TanrikutInformation technology is an indispensable element in applications in today's industrial era.

OBJECTIVE: To explore the effects of muscle fatigue on male handball players' shooting accuracy and ball speed. METHODS: Sixteen elite handball players (M-age = 17.1 +/- 1.7 years) participated in the laboratory and the field-testing sessions. Running speeds equal to 75% of participants' maximal oxygen uptake (VO2max) values from laboratory tests were used as the initial velocity for the 30-15 intermittent fitness test (30-15(IFT)) in the fatigue protocol. Participants shot to the target at random visual signals placed behind the target before and after fatigue. In order to measure wrist acceleration and ball speed, an accelerometer and a radar gun are used respectively and numbers of accurate and inaccurate shots also recorded. RESULTS: There were no significant differences between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots, and ball speed. Only wrist acceleration in the Y axis (M-pre(-fatigue) = 33.12, SD = 1.17msec; M-post - fatigue = 34.50, SD = 1.21msec) was affected by the fatigue protocol in inaccurate shots (p = 0.042). CONCLUSIONS: Muscular fatigue does not affect shooting accuracy and ball speed in male handball players.Conference Object Citation - WoS: 1Citation - Scopus: 4Fpga Based Dco-Ofdm Phy Transceiver for Vlc Systems(Institute of Electrical and Electronics Engineers Inc., 2019) Levent, V.E.; Uysal, M.; Saglam, G.; Ugurdag, H.F.; Fajar Rizqi Annafianto, N.; Aydin, F.; Kebapci, B.; Tesfay, Shewit Weldu; Annafianto, Nur Fajar RizqiSatisfying the demand for high bandwidth and low latency in Visible Light Communication (VLC) systems is a difficult challenge. VLC channels exhibit frequency-selectiveness at peak-speeds. This phenomenon generates a serious inter-symbol interference effect. A physical layer (PHY) design that can carry out physical layer communication tasks to overcome all these strains is required. In this study, an FPGA based PHY design that implements DCO-OFDM algorithm is described for VLC systems. A demo was performed with the developed PHY design using an LED transmitter and a photodetector receiver. © 2019 Chamber of Turkish Electrical Engineers.Conference Object Citation - WoS: 1Citation - Scopus: 1Design and Development of a New Tactile Stimulator(Ieee, 2019) Kazma, Coskun; Levent, Vecdi Emre; Aydin, NizamettinWe have designed and implement a tactile stimulator to obtain information from the central nervous system. Our system consists of two main components. The first one is tactile stimulator, which was designed to stimulate index and middle finger tips, stimulating mechanoreceptors according to the test protocol. Second one is a personal computer running a desktop software for the implementation of test protocols. The flow is as follows; the subjects are asked the question of the test protocol through the personal computer. The parameters are then transmitted to the embedded board on the machine. The embedded board drives step motors to apply the relevant test parameters. The desktop software expects the individual to answer the question using the right or the left mouse button of the computer mouse. After answering the relevant question, the test proceeds to the next step. According to the test protocol, the stimulation process of the mechanoreceptors located at the index and middle finger tips must start and terminate at the same time. From this perspective, the embedded board with 3 18F46K22 PIC microcontrollers produces 2 square wave signals with different frequencies and amplitudes at the same time. The embedded system card developed with the PIC microcontroller is also developed with FPGA. The system has also been tested on 24 blue and white collar employees and a significant result has been obtained.Article Citation - WoS: 16Citation - Scopus: 23Balance Training in Modern Dancers Proprioceptive-Neuromuscular Training Vs Kinesio Taping(Science & Medicine inc, 2018) Tekin, Demet; Agopyan, Ani; Baltaci, GulKinesio tape and proprioceptive exercises are both used for increasing balance in dancers. The purposes of this study were to: a) determine the acute effect of kinesio tape (KT) application on the ankle joint on balance performance, b) investigate the effects of an 8-week proprioceptive-neuromuscular (PN) training program on balance performance, and c) compare their effects vs modern dance technique classes alone. Thirty-three trained, university-level modern dance students (9 male, 24 female) were divided randomly into three groups: kinesio tape (KT, n=11), proprioceptive-neuromuscular (PN, n=11), or control (n=11). Static (turn-out passe-opened eyes/releve and turn-out passe-closed eyes/flat foot), semi-dynamic (airplane), and dynamic balance (monopodalic-straight and -transverse in a turn-out passe-eyes opened/flat foot) tests were performed before and after the intervention. One day after pre-tests, KT mechanical correction technique was applied to the left ankle joint (supporting leg) in the KT group, and tests were repeated to determine the acute effect of KT. The PN group participated in an 8-week balance training program (2 days/wk, 60 min/day) involving exercises using stable and unstable surfaces. Significant improvements were observed for all static and dynamic balance tests in the PN group; semi-dynamic airplane and dynamic monopodalic-straight and transverse tests improved in the KT group; and only semi-dynamic airplane test scores changed significantly for the control group (p<0.05). Our findings suggest that with the exception of the semi-dynamic airplane test, both PN training and KT application were more effective at improving balance performance for modern dancers than modern dance technique classes alone.
