Organizational Change and Applicability of Six Sigma Management Model in the Turkish National Soccer Team
(Gdansk Univ Physical Education & Sport, 2018) Cobanoglu, Halil Orbay; Terekli, Mustafa Serdar; Gursakal, Necmi; Sever, Necip Serdar
Background: In recent years, the Six Sigma Methodology has been primarily applied to the enhancement of performance. The purpose of this study was to implement Six Sigma Management Models in the Turkish National Soccer Team. Material and methods: 24 matches of the Turkish National Soccer Team constituted the sample of research. The DMAIC method was used in this study. For statistical analysis of research data, IBM SPSS 18.0 for Windows and Minitab 17 statistical software program were used. As statistical techniques, brainstorm, fishbone, chi-square correlation analysis, Spearman correlation test, process capability analysis and control charts were used, which were the six sigma tools. The numerical values obtained were tested at P < 0.01 and P < 0.05 significance levels. Result: As a result of the research, a statistically significant correlation was found among the match outcomes of the Turkish National Soccer Team and the game formation (P = 0.04), the positive shoot rate (P = 0.03), the positive defence rate on the first zone (P = 0.00) and the positive defence rate on the second zone (P = 0.00). As a result of the improvement, the z bench value for the positive defence rate on the first zone was increased from 0.47 to 0.59. Conclusion: It can be said that the Six Sigma Management Model is applicable for coaching or training in soccer.

Isokinetic Knee Muscular Strength Is Associated With Hematologic Variables in Female Modern Dancers
(Spanish Assoc Sports Performance Analysis-aearedo, 2018) Agopyan, Ani; Tekin, Demet
It is important to expose the risk factor in injury in the context of the health and the careers of dancers. 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.

Balance Training in Modern Dancers Proprioceptive-Neuromuscular Training Vs Kinesio Taping
(Science & Medicine inc, 2018) Tekin, Demet; Agopyan, Ani; Baltaci, Gul
Kinesio 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.

Parametric Trigger Signal Generation With Microcontroller and Fpga Based Architectures
(Ieee, 2019) Kazma, Coskun; Levent, Vecdi Emre; Aydin, Nizamettin
A new system to obtain information from the central nervous system has been developed. Our system consists of two main components. The first of these components is the machine, which is located on the index and middle finger tips, stimulating mechanoreceptors according to the test protocol. The other 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 system board on the machine. The embedded system board takes step motors to apply the relevant test parameters. The desktop software expects the subject to answer the question using the right and/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 system board with 3 18F46K22 PIC microcontrollers produces 2 square wave signals with different frequencies and amplitudes simultaneously. The embedded system card developed with the PIC microcontroller is also implemented on an FPGA. The system has also been tested on 24 blue- and white-collar employees and a significant result has been obtained.

Skeletal Muscle Fatigue Does Not Affect Shooting Accuracy of Handball Players
(Ios Press, 2019) Akyuz, Beyza; Avsar, Pinar Arpinar; Bilge, Murat; Deliceoglu, Gokhan; Korkusuz, Feza
BACKGROUND: Shooting accuracy and ball speed are important factors relating to scoring in handball that could be affected by skeletal muscle fatigue. 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.

An Integrative Approach To Relationship Marketing, Customer Value, and Customer Outcomes in the Retail Banking Industry: a Customer-Based Perspective From Turkey
(Routledge Journals, Taylor & Francis Ltd, 2019) Sayil, Emine Mediha; Akyol, Ayse; Simsek, Gulhayat Golbasi
Given how important it is to provide superior value to customers and to maintain customer loyalty for a sustainable competitive advantage, the aim of this paper is to examine the relationships among relationship marketing components of - trust, competency, commitment, communication, and conflict handling, - relationship investment, relationship quality, perceived customer value, satisfaction and loyalty in an integrated framework in the Turkish retail banking industry. 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.

Solving the Sales Problem of a Poultry Meat Company With Thinking Process
(Future Acad, 2019) Onursal, Fatma Serab; Aydin, Selman; Birgun, Semra
The use of new technology in order to achieve real improvement and to increase productivity in a business can be effective in the long term only through the correct analysis of the current status of the business. After the current status is detected, the improvement studies should be continued towards the existing constraints and the studies for eliminating new constraints that will occur at certain time intervals should be repeated. Unless improvement can be sustained, long-term solutions cannot be in question. In family foundations or charitable foundations; factors such as close relationships, special connection, and lack of education come to the forefront, and bulky organizations prevent innovative developments. There is a need for approaches that see the business as a whole and predict the future by uncovering the real situation. One of them is Theory of Constraints. In this paper, a case study is presented in which the problems arising from production and planning, sales and management mistakes in a food business, which is a charitable foundation, were elevated with the application of Theory of Constraints. In the study, the steps such as Current Reality Tree, the Evaporating Cloud and the Future Reality Tree from the Thinking Process were realized. As a result of putting the recommendations into practice, significant improvements were made in the business under examination. (C) 2019 Published by Future Academy www.FutureAcademy.org .UK
Toc-Thinking Process Approach for Problem Solving in Trademark Registration Process
(Future Acad, 2019) Birgun, Semra; Erol, Serpil; Alpar, A. Arzu Ceylan
Industry 4.0 has caused many changes in commerce as well as in industry. Institutions should therefore revise their strategies and make strategic decisions that will adapt to today's digital world. In the current physical or digital business competition environment, firms want to make their products more attractive by branding and delivering them to large masses. A brand is a feature that separates the product or company from the others and is an advantage both the produces and the consumer. Firms have a wider market share by ensuring the transportation and awareness of its products, and while ensuring its sustainability, consumers can gain prestige, protect their rights, and so on. The trademark must be registered in order to be valid. However, when the application was made in Turkey rejection rate of the brand has increased steadily. This situation causes great waste for the applicant and the applicant institution. In this paper, a study has been conducted with the aim of revealing how problems should be resolved by investigating the causes of rejection of applications and thus increasing the acceptance rate. In this study, Thinking Processes application was made within the framework of the Theory of Constraints approach, which aims to achieve continuous improvement by removing constraints. Thus, it is foreseen that there will be a guide on the possible mistakes of the firm managers who will make a trademark application and how these problems can be resolved.

(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.
Satisfying 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.

The Relation of The Duration of Work in Dentists With Postural Problems, Range of Motion and Pain
(Bezmialem Vakif Univ, 2020) Tekin, Demet; Koksal, Mesut
Objective: The aim of this study is to determine the relationship between cervical and lumbar range of motions, pain and postural problems with the time spent in the occupation in dentists. Methods: A total of 56 dentists (27 males, 29 females), participated in this research as a volunteer (age=29.55 +/- 9.5 years). Firstly, the participants were divided into 3 groups according to the working years in their life and the time spent at unit during the day; they were also divided into 2 groups according to the intermittent or uninterrupted working conditions during the day. Cervical and lumbar joint range of motions were measured to determine limitations. The McGill pain scale survey was used to evaluate the pain. Kruskal Wallis and Mann-Whitney U tests with a posthoc Bonferroni test were used for all statistical analyses. Results: It was seen that the cervical and lumbar joint range of motions decreased, and the postural deformities in the spine and knee were observed and the level of pain increased significantly in comparatively to the excess of the time spent in the profession. However, in the analysis according to the time spent at the unit during the day, only the decrease in the range of motion of the regions was determined with the increase of the time spent at the unit during the day. Conclusion: With the increase in the working years in the dentists, it was revealed that the limitation of the range of motion increased and posture disorders and pain were formed. It is thought that all these problems will be caused by working in non-ergonomic environments for a long time. In this respect, it is important to include experts in the field of physiotherapy in the courses given under the name of preventive medicine. As a result, it can be said that the health problems encountered with the increase in time spent in the profession have increased.

(Cukurova Univ, Fac Medicine, 2020) Eroglu, Nermin; Temiz, Gamze
Purpose: This study was planned and applied semi-experimentally to examine the effect of education given to patients receiving infertility treatment on stress and coping with stress. Materials and Methods: The study is semi-experimental. It was held between May 2017 and January 2018 with individuals who applied to a foundation hospital in Istanbul province for IVF treatment. The sample was made up of 40 infertile individuals. The data were collected by the researcher through face-to-face interview method. Training was given after pretesting. Post-test was performed one month after the training. Results: The pre-education stress scale of middle school graduates of infertile women was higher, this difference disappeared after education, and there was a statistically significant difference between the infertility stress and coping scale subscale mean scores. As the use of active ignoring, active struggling and passive ignoring coping methods of women, the use of the methods of coping with the infertility subscale scores increased, the infertility stress subscale scores increased.. Conclusion: In this study, the relationship between infertility and stress research was investigated and it was concluded that the treatment process and results are an important source of stress in patients. According to the results obtained, it is recommended to determine the stress level and methods of coping with stress, and provide training and counseling on patients who apply to the hospital for infertility treatment.
Potential Publicity of the Remnant Space in the Upper Modern City: London Low-Line Railway Example
(Yildiz Technical Univ, Fac Architecture, 2020) Akaydin, Ozlem Eren; Onal, Feride
Cities have been exposed to an uncontrolled change, consumption, and transformation process because of the profit-oriented planning systems with the developments dependent on technology and capital. Due to the reasons that can be detailed under major circumstances such as the increase in the private vehicle usage, the planning approaches generated for public spaces during the modernism period, the determination of regional distinctions with stable boundaries, the disconnection in the transitions of public-private spaces, and the inaccurate applications in decontamination of city centres from industry, military and massive transportation areas; caused the existence of the remnant space problematic nature. Especially in cities that are developed very fast, urban outdoor spaces cannot adapt to this process and transform into remnant spaces with generating different problems in daily life. The main theme of the study is to define these problematic urban pieces formally and conceptually in today's upper-modern city context, which is defined with extremism. In the upper-modern city, there are critical changes in public space because of globalization. All the terms and qualifications that are attached to public space; remain incapable because those changes occur in a very fast time period. To explain the upper modern urban space through the scope of anthropology; the urban fabric should produce daily identical interactions, but in upper-modern cities, urban fabric has various losses because of temporary interactions. In the scope of anthropology, the historical and contextual side of the urban space is so valuable, unique, and nominative but in an upper-modern cities, urban space is general and has connectivity problems with its context and close environment. After expanding the meaning of the upper-modern city; remnant space is defined within the interactive relation of the existing similar terms in the international literature. Lands of contempt, empty space, border vacuums, defensible space, lost space, space of uncertainty, awkward space, residual space, gapscape, modern wasteland, and liminal space are associated with the remnant terms. These associated terms helped to explain the remnant space through the emphasis of potentials as new public spaces of the upper-modern cities. The aim of the study is to evaluate the potentials of remnant spaces within the publicity, questioning their spatial offsets in the upper modern city and emphasise the necessity of regenerating these spaces through a theoretical approach that focuses on the human experience. In this context, the Low-Line Railway, which is one of the most important transportation arteries of London, has been examined as a remnant space. The Low-Line refers to the important city flows along the route in between Southwark tube station in the west, London Bridge Station in the east. The most important key approach is to evaluate a remnant space within its unique context to explore its core potential of the remnant space. For this reason, the remnant space is evaluated within its dynamic context by addressing a group of specifications that emphasise the human scale importance as a basis. Resilience; adapting to contextual changes. Placemaking; defining the functional requirements by understanding user needs, regeneration; supporting the remnant space with new values. Social interaction; encouraging active living and recreation. Exemplary; creating an example approach by enhancing biodiversity within the city. Green infrastructure; generating nature-based sustainable solutions for the area. Active pedestrian flow: providing opportunities to reduce the dominance of vehicles. Communication and engagement; getting involved in the user experience, residents, and businesses into the process. Through these criteria, awarded competition projects have been evaluated and potentials of the remnant space have been exposed by enhancing user experience importance.

The Governance of Turkey's Cyberspace: Between Cyber Security and Information Security
(Routledge Journals, Taylor & Francis Ltd, 2020) Eldem, Tuba
This article explores Turkey's multifaceted cyberspace governance policy and argues that positioned between two opposites of cyberspace governance that has close military and security ties to the West, and domestic Internet policies more similar of Russia-China axis, Turkey should be considered as a swing state in global cyberspace governance debates. The article shows that despite her official discourse on multi-stakeholderism and its compliance with the emerging norms in the Euro-Atlantic alliance concerning cyber-security, cyber-crime, and cyber-defense; Turkey's domestic Internet policy converges towards the Russia-China axis characterized by the rise of information controls and increasing efforts to establish "digital sovereignty" to national cyber space.

How Should Data Science Education Be?
(Igi Global, 2020) Gursakal, Necmi; Ozkan, Ecem; Yilmaz, Firat Melih; Oktay, Deniz
The interest in data science is increasing in recent years. Data science, including mathematics, statistics, big data, machine learning, and deep learning, can be considered as the intersection of statistics, mathematics and computer science. Although the debate continues about the core area of data science, the subject is a huge hit. Universities have a high demand for data science. They are trying to live up to this demand by opening postgraduate and doctoral programs. Since the subject is a new field, there are significant differences between the programs given by universities in data science. Besides, since the subject is close to statistics, most of the time, data science programs are opened in the statistics departments, and this also causes differences between the programs. In this article, we will summarize the data science education developments in the world and in Turkey specifically and how data science education should be at the graduate level.
