Anatomy and Assessment of the Autonomic Nervous System
Gülseren Akyüz,Merve AKDEN？Z LEBLEB？C？ER
Türkiye Fiziksel Tip ve Rehabilitasyon Dergisi , 2012,
Abstract: Autonomic Nervous System (ANS) is responsible for the vegetative functions of the body. It is composed of many ganglions, plexi, cerebrospinal nuclei and nerves. ANS, which is also known as visceral or vegetative nervous system, helps to control many functions, such as blood pressure, gastrointestinal motility, glands, bladder functions, sweating and body temperature. ANS innervates all the smooth muscles and the heart, and keeps to stabilize body functions within certain limits. ANS is composed of 3 components: sympathetic system (thoracolomber-adrenergic), parasympathetic system (craniosacral- cholinergic) and enteric system (nonadrenergic- noncholinergic). Autonomic nerves are classified with regard to their origin from central nervous system, the distribution of peripheral ganglions, their various physiological effects on visceral organs, and response to pharmacological agents. It is essential to know the anatomy and the physiology of the ANS, in order to evaluate disorders, achieve the correct diagnosis and to plan accurate treatment.

Abstract: Background: In this study, it is aimed to evaluate the reliability and validity of the Turkish version of the Burden Assessment Scale.Methods: The study was carried out on 100 volunteers who were caregivers of in- or outpatients at a university hospital, department of psychiatry. The diagnoses of the patients were schizophrenia (25%), bipolar disorder (22%), major depressive disorder (24%), and anxiety disorder (29%). The mean duration of the illness was 8.2±8.7 years. For the concurrent validity, the Perceived Family Burden Scale and the Zarit Caregiver Burden Scale were used. In the statistical analyses, internal consistency, item-total score correlation, explorative factor analysis, correlation with other scales were calculated.Results: The Turkish version of the Burden Assessment Scale was prepared after the translation and back-translation of the original scale and after the consensus on the translated form. In the internal consistency analysis, Cronbach alpha coefficient was found to be 0,894 and item-total score correlation coefficients were between 0.297 and 0.742. In the explorative factor analysis, a five-factor solution explaining 67.2% of the total variance was obtained and the conceptual themes of the factors were limitations in daily life, negative emotions, worry for the patient, losses of the caregiver, and disruption in activities. The correlation of the Burden Assessment Scale with the Perceived Family Burden Scale was r=0.485 and with the Zarit Caregiver Burden Scale was r=0.610. Conclusion: It is demonstrated that the Turkish version of the Burden Assessment Scale which is convenient in the milder forms of psychiatric disorders and which is developed for the assessment burden of patients on their caregivers is reliable and valid.

An Application for a Production System by Using Simulation Modelling Tecniques
Celaleddin Lu,Z. Rafet Akden
Asian Journal of Information Technology , 2012,
Abstract: With the increasing challenge confronting businesses to develop better systems for providing good and services. Computer simulation is emerging as a powerful decision making tool for achieving significant improvements in the design and operation of manufacturing systems. We decided to write this paper with the hope of removing mystery- surrounding simulation by providing practical techniques for managers and engineers who have been too skeptical and perhaps even timid about putting it to use. In a highly competitive manufacturing industry simulation lets you experiment with a computer model of your system in compressed time giving you decision making capability without disturbing your system. During this workshop, production lines of a factory is modeled and simulated. Multiple replications are made for getting outcomes of the model. Regarding to outcomes of the model, bottlenecks analysis, forklift work distribution analysis are made. Proposal solutions are made for this production system referring to the analyses of the simulation model outcomes.
Data Processing System for a Production Factory
Celaleddin Lu,Rafet Akden Z
Asian Journal of Information Technology , 2012,
Abstract: Scope of this project is to control production processes and outputs of production, in order to reduce cycle time, production losses and to increase product quality and productivity. In order to take production parameters under control, one should get and process data, which could be taken from pre-process, in process, after process. These data give us information about row material needs, stock level for semi-product and products. This information may be gotten from pre-process or in process or after process. These data shows us row material needs, stock levels. If any of these data were missed, final decision would not be made. Data processing system is developed for an automobile glass-manufacturing factory, in order to increase product quality, decrease cycle time and reduce semi-product losses between production lines.

Abstract: As known; goal programming, which is a type of multi-objective programming that its priority is satisfaction and based on optimization, allows decision maker to design an optimal system. Hence; a solution set provides simultaneous satisfactory is determined. Fuzzy goal programming model is analyzed in two different forms with respect to objective preemptive priority structure. In the first form, an importance level of preferences is specified quantitatively. In the second form, preference priority is added to model as linguistic information.In fuzzy goal programming; additive model which is adapted to mentioned two forms is developed by Tiwari, Dharmar and Rao (1987). Goal programming based on more satisfaction instead of optimization. Thus, using of fuzzy logic in this area is appealing. Goal programming approaches based on fuzzy logic is developed by the time of progress and every approach is aimed at getting better models. A model that allows preemptive priority in fuzzy goal programming in order to reach maximum membership and makes its solution to one structural problem is developed by Chen and Tsai (2001). Additive model which is proposed by Chen and Tsai allows for making desired success of level for every fuzzy goal by a decision maker. Thus, relative importance of these goals is stated clearly. In this paper, additive model used in fuzzy goal programming applied to plastic factory which is established in Izmir. The relationship between goals of production planning chief and model outputs is evaluated and presented.

Abstract: The aim of this study is to investigate the effectiveness of context based and traditional physics problems comparatively. First of all, we reviewed the literature and assigned some criteria in order to prepare context based problems, and developed two different tests as context based and traditional based physics tests based on the described criteria. Secondly these tests were applied to 30 high school students. Also we held an interview with randomly selected five students in order to determine the views of students about the differences between these two different tests. A semi-structured interview form was used in this interview process. Finally, we used a paired-samples t test in order to compare students’ achievements scores on these two different tests. Content analysis method was performed to analysis qualitative data collected through interviews. Study findings showed that there was no significant difference between students’ context based and traditional test scores. However, students appreciated context based problems more understandable, concrete and interesting than traditional ones.

Abstract: 23rd International Universiade Olympic Games will be held in Izmir between July 6 and 16 and is the second largest organisation after World Olympic Games. Almost 8000 athletes from 170 different countries will attend to the games and a well organised airway transportation traffic is one of the major concerns. Thus optimization of the airway traffic is needed also because of the expected increase of the density of Adnan Menderes Airport due to continuing national air traffic. Waiting time optimization of the incoming and outgoing planes is a necessity. So it will be examined if a new landing field is need or not. In order to do this the most crowded day 08 30 2002 is selected as a reference and analysis has been carried. Data have been collected from the observation of 100 planes that had been used on the selected date.

Merve Bi？er, Murat Arslan, Vedat Ulug, Zekeriya Güner, Suleyman Akarsu, Mert Gol
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.612123
Abstract: Within the advance ports and instruments, laparoendoscopic single-site (LESS) surgery has been increasingly used among gynaecologic surgeons. In addition, advanced port systems have enabled to perform concomitant surgical procedures via transumbilical incision. However, combined surgical operations are rarely reported in the literature, particularly in gynaecology. This case report presents a 42-year-old woman who undergo concomitant LESS hysterectomy and nephrectomy due to deep infiltrating endometriosis (DIE) and end stage renal disease. The operation is performed in approximately 3 hours without any complications, and the patient is discharged on postoperative third day. This case demonstrates that complex concomitant operations even in a patient with DIE can be performed using a LESS surgical approach.

Abstract:

Biosphere Reserves (BR) are special areas or regions highly recognized for their conservation, logistic functions and sustainable development initiatives. However, not much work has explored into the BRs’ roles or functions as tourism learning destination, especially during the early years of their recognition as BR. This article aims to identify the mechanism utilised in the learning tourism function at Tasik Chini Biosphere Reserve since its inception in 2009 to the present year of 2013. The results reveal that learning of science and culture of the locals are the two-tier perspectives utlised in conceptualizing a tourism learning destination. Activities introduced in the specific themes of The Sustainability of Tropical Heritage fulfils the fundamental need of deep learning of scientific research and learning of the BR’s ecosystem, while the Ecosystem Health fulfils both deep and surface learning of the young visitors. The cultural knowledge of the community, on the other hand, offers a unique and authentic experience to the learners or visitors. As a learning tourism destination, the learning community, nevertheless, expects that the standard of tourism services should not be marginalised and must meet the high standard of tourism services. It is imperative that the science of Biosphere Reserve and the local culture are linked to set a holistic foundation in the creation of the learning programmes at the Tasik Chini Biosphere Reserve.

Türkiye Fiziksel Tip ve Rehabilitasyon Dergisi , 2008,
Abstract: Paget’s disease of bone (PD) is characterized by focal increases in bone turnover of unknown etiology that affects mainly elderly population. PD is the second most common metabolic bone disease after osteoporosis in western countries. The diagnosis of PD is made most commonly, incidentally in patients undergoing biochemical or radiologic investigations for other conditions. Pain in the involved bone(s) is the most common symptom of PD. Bisphosphonates are first line drugs in treatment of PD. We report a patient who was previously followed with the diagnosis of osteoporosis, partially improved from bisphosphonate treatment and diagnosed as PD in our clinic.Turk J Phys Med Rehab 2008;54:184-6.
