    Electric vehicles (EVs) are expected to reduce carbon emissions from transportation. For this reason, many vehicle manufacturers, countries and international organizations develop their energy and transportation policies in this direction and also support them with practices. As a result of the policies implemented and developments in battery technologies, serious increases are expected in the sales of the EV sector. However, there should be sufficient charging stations for EV charging. The increase in charging stations is expected to cause some positive and negative effects on the grid. In order for electric vehicles to be more acceptable in terms of power systems, it is necessary to understand what kind of electrical character they show. In this article, EV electrical modeling is performed over a charging period by Monte Carlo Simulation using the actual charging data of some EV models charged in a single phase 7, 2 kW-240 V charger. The generated probabilistic model was validated by comparing it with real data. Thus, a reliable modeling has been presented for EV, which is a new load in power systems

    Giriş: Dünyada ve ülkemizde genel nüfus yaşlandıkça bu grubun sağlık bakı- mına olan gereksinimleri arttığından yaşlı bireylerin bakım gereksinimlerinin belirlenmesinde sağlık durumunun değerlendirilmesi önemlidir. Amaç: Çalışma yaşlıların sağlık durumlarını değerlendirmek amacıyla yapılmıştır. Yöntem: Aralık 2010 tarihinde, iletişim problemi olmayan, bağımsız veya yarı bağımlı olan, 65 yaş üstü toplam 212 yaşlı bireyde tanımlayıcı olarak yapılmıştır. Yaşlı sağlığını değerlendirmek amacıyla araştırmacılar tarafından geliştirilen sosyodemografik özellikler, fiziksel yeterlilik durumu ve sistemlere özgü fiziksel muayene bulgularını içeren “Yaşlı değerlendirme Formu” kullanılmıştır. Bağımlılık durumu, yaşam bulguları, beden kitle indeksi hesaplanmış, sistemlere özgü değerlendirilmesinde baştan-ayağa ve sistemlerin fiziksel muayenesi yapılmıştır. Bulgular: Çalışmada değerlendirmeye alınan bireylerin 65-95 yaş arasında (70.74+7.07), %55,7’sinin erkek, %28.3’ünün ilkokul mezunu, %10.8’inin alerjisi olduğu, %54.7’sinin sigara kullandığı, %42.5’inin barsak alışkanlıklarında sorun yaşadığı, %26.4 ’ünün de uyku sorunu olduğu belirlenmiştir. Yaş- lıların %63.2’sinin en az bir ameliyat geçirdiği, %61.8’inin hipertansiyon başta olmak üzere diyabet ve kalp yetersizliği gibi kronik bir hastalığı, %50.9 ’unun ağrı yakınması olduğu bu nedenlerle %84,9’unun sürekli kullandığı ilaçlarının olduğu saptanmıştır. Yaşlıların %58.5’inin bağımsız olarak fiziksel gereksinimlerini karşıladığı, %80.7’sinin açık ve anlaşılır bir konuşmasının olduğu, %72.6 ’sının baston, gözlük, tekerlekli sandalye, diş protezi kullandığı, sistemleri ile ilgili fiziksel muayenesinde en yoğun kas zayıflığı, yürüme güçlüğü (%71.2), ödem, noktüri, yorgunluk, çarpıntı (%65.6) öksürük, dispne, balgam çıkarma (%61.8), halsizlik, baş ağrısı, baş dönmesi (%59.4) sık idrar yapma, idrar kaçırma (%47.6) sorunu belirlenmiştir. Elde edilen sonuçlar yaşa bağlı anatomik ve fizyolojik değişkenlerin yansıması olarak değerlendirilmiştir. Sonuç: Yaşlıların bağımsızlıklarını etkileyen sağlık sorunları görüşme, gözlem ve ayrıntılı fizik muayene ile belirlendiğinden hemşirelerin etkinliği önemlidir

    This study aimed to evaluate the effect of a levonorgestrel-releasing intrauterine system (LNG-IUS) on the sexual function of women. Participants who had abnormal uterine bleeding (AUB) complaints with LNG-IUSs were included (study registration: Kanuni Sultan Suleyman Training and Research Hospital, 2018/10/34). The demographic data of all participants were recorded. The female sexual function index (FSFI) questionnaire was used to participants before the insertion of LNG-IUSs and 6 months after its insertion. FSFI scores were calculated at both timepoints and were compared. The total FSFI score after LNG-IUS insertion was significantly higher than the total FSFI score application (p < .001). The scores of the desire, arousal, lubrication, orgasm, satisfaction and pain categories significantly increased after LNG-IUS compared to those before LNG-IUS. As a result, the present study demonstrated that after LNG-IUS insertion, these women had higher FSFI scores.Impact Statement What is already known on this subject? There are many publications in the literature comparing the effects of LNG-IUSs, IUSs, OCs and other contraceptive methods on female sexuality. However, there are markedly few studies that compare sexual function before and after LNG-IUS insertion. What do the results of this study add? The total FSFI score after LNG-IUS insertion was significantly higher than the total FSFI score before the insertion (p < .001). The scores of the desire, arousal, lubrication, orgasm, satisfaction and pain categories significantly increased after LNG-IUS insertion compared to those before the application. The number of participants with FSFI scores ≥26.5 before LNG-IUS insertion was 17 (12.5%), and this number increased to 71 (52.5%) after the application What are the implications of these findings for clinical practice and/or further research? This study contributes to the literature because there are few researches that compare sexual function before and after LNG-IUS insertion. As a result of our study, sexual dysfunction decreased after LNG-IUS, and the scores increased in all sub-groups together with the total FSFI scores

    The purpose of this study was to analyze, which recreational sport or non- sport such as cultural/ art activities that university students prefer in their leisure time and underlying reasons that constrains participating in these activities with regard to different variables. Randomly chosen 339 students from The Faculty of Arts and Faculty of Sciences and Engineering at University of Dumlupiınar volunteered for the study. In this research as a data collection tool “Leisure Constraint Scale” was used. During the evaluation of the data in addition to descriptive statistical methods such as Percentage (%) and frequency (f) Independent Samples t-test and One way Anova were used. As a result it was found that 19.2% participants choose recreational sport activities in their leisure time. In addition, significant differences have emerged between participants’ gender and constrains to leisure in "lack of information", "lack of friends" and "time" sub-dimensions, between age and barriers to leisure in "time" sub-dimension, and between average monthly income levels and constrains to leisure in "individual psychology" and "facilities / services" sub dimensions (p <0.05). But no significant differences were found according to activities that they choose in their leisure time

    Introduction: A 25 year-old woman admitted to our clinic due to left lomber pain, weakness and abdominal mass. On computerized tomography, 140×110×50 mm in diameter solid mass was detected in upper pole of the left kidney on computerized tomography (CT). The patient underwent left radical nephrectomy and histopathological examination of the specimen was reported as pyelonephritis. Six months after the operation, the patient admitted to our clinic with huge intraabdominal mass. It was defined as hematoma or abcess on CT. One thousand cc necrotic clot like material was evacuated in exploration. Histopathological examination of this material indicated desmoplastic small round cell tumor
