Sanal müze sistemleri, eğlenceli ve eğitici yaklaşımları sayesinde kültürel içeriklerin iletişimi için önemlidir. Bu bağlamda sanal müze deneyimi yaşayan ziyaretçilerin bu durumdan memnun olup ...olmadıklarını ortaya koymanın önemi de kolayca anlaşılmaktadır. Gerçekleştirilen çalışmada, sanal müzede sanal tur yapan bireylerin memnuniyet düzeyleri ortaya konmuştur. Bu amacı gerçekleştirmek için sanal müze deneyimi yaşayan 227 kişiden veriler toplanmıştır. Verilerin toplanması dijital ortamlarla gerçekleştirilmiştir. Araştırma sonucunda, sanal tur memnuniyeti ve sanal ortamın kullanılabilirliği olmak üzere iki değişkenli bir yapı ortaya çıkmıştır. Bununla beraber sanal ortamın kullanılabilirliği ile sanal tur memnuniyeti arasında pozitif yönde anlamlı bir ilişki olduğu görülmüştür. Buna göre sanal ortamın kullanılabilirliği arttıkça, sanal tur memnuniyeti artmaktadır.
Bireylerin sanal tur kullanım niyetini etkileyen faktörlerin Teknoloji Kabul Modeli’ne güven dış değişkeni eklenerek geliştirilen bir modelle belirlenmesi amaçlanmaktadır. Veriler mobil internet ...kullanıcısı olan ve en az bir kere sanal tur uygulamasını kullanmış olan 511 kişiden çevrimiçi anket yöntemi ile toplanmıştır. Verilerin tanımlayıcı istatistikleri, güvenilirlik analizi için IBM SPSS Statistics 21 paket programı kullanılmıştır. Yapısal Eşitlik Modeli için AMOS 21 paket programı kullanılarak analiz gerçekleştirilmiştir. Analiz sonuçlarına göre; güvenin algılanan kullanım kolaylığı ve algılanan fayda üzerinde anlamlı ve pozitif yönde bir etkisinin olduğu, algılanan kullanım kolaylığının algılanan fayda ve tutum üzerinde anlamlı ve pozitif yönde bir etkisinin olduğu, algılanan faydanın tutum üzerinde anlamlı ve pozitif yönde bir etkisinin olduğu tespit edilmiştir. Fakat algılanan faydanın niyet üzerinde doğrudan anlamlı ve pozitif bir etkisinin olmadığı tespit edilmiştir. Dijital turizm çağında şehirler ve destinasyonlar hakkında bilgi edinmede sanal tur kullanımının önemi ve gerekliliği vurgulanmıştır.
Abstract
Traffic simulation models are one of the most important tools that are widely used to analyse and manage transport systems. These tools are used to model complex traffic sites and evaluate ...various traffic alternatives and testing their effect prior to application in real sites. Median U- turn is an example of such complicated sites. There are many microsimulation tools such as VISSIM, ALIMSUN and PARAMICS. The goal of this study is to develop the simulation model of median U-turns and compares between VISSIM and PARAMICS models. The data were collect from two-selected site at Al-Diwaniyah city, Iraq. The data used in verification of the developed model represent the through traffic volumes and turning traffic volumes at both directions as well as the average queue length created at the U-turn site. The calibration and validation process of the developed models show that both VISSIM and PARAMICS models can provides reasonable approximation for real traffic at the selected site. Further research is needed to examine these tools based on additional sites and to apply such tools to examine different scenarios to enhance traffic conditions at U-turn sites.
En bloc resection of bladder tumors (ERBT) has been used as a treatment option to improve pathologic diagnostic accuracy in non-muscle invasive bladder cancer. We report on the feasibility of a novel ...ERBT technique using an electrosurgical snare with flexible cystoscope: flexible cystoscopic En bloc Snare Resection of Bladder Tumor (f-ESRBT).
We used the electrosurgical snare to resect a superficial bladder tumor after injection of 50% glucose in the submucosa at the tumor base. We collected each resected tumor with a basket catheter and coagulated the resected area with a coagulation electrode. A flexible cystoscope was used for all procedures.
We performed 10 operations. Mean tumor size was 10.2 ± 7.3 mm and mean surgery time was 13.8 ± 6.8 minutes. All procedures were performed without complications. Results showed f-ESRBT to be simple and minimally invasive and to enable accurate pathologic diagnoses.
f-ESRBT is a feasible treatment option for small and non-muscle invasive bladder cancer.
To examine oncological, surgical, and functional outcomes of radical prostatectomy (RP) in patients with history of transurethral resection of the prostate (TUR-P).
Retrospective analysis of 18,681 ...RP-patients including 470 patients with previous TUR-P at a single institution (2002–2015). Kaplan-Meier as well as multivariable Cox and logistic regression analyses compared surgical, oncological, and functional outcomes between TUR-P and non-TUR-P patients after propensity score matching (nearest neighbor in a 1:3 fashion).
After propensity score adjustment, pathological and surgical results were similar between both groups. Specifically, rates of positive surgical margins and nerve-sparing (NS) procedure did not differ between groups (positive surgical margins: 18.5% vs. 17.2%, P = 0.7; nerve-sparing: 89.4% vs. 91.6%, P = 0.5). In addition, there was no difference in mean operating room time (185 vs. 184 minutes, P = 0.6), blood loss (710 vs. 666 ml, P = 0.1), and catheterization time (12 days, P = 0.3). In multivariable analyses, TUR-P patients did not exhibit higher risk of biochemical recurrence, metastatic progression, or mortality (all P > 0.05). However, TUR-P patients exhibited higher risk for urinary incontinence at third month (OR: 1.47; 95% confidence interval CI 1.01–2.12, P = 0.04) and first year (OR: 2.06; 95% CI 1.23–3.42, P = 0.006) and worse 1-year erectile function recovery (OR: 0.48; 95% CI 0.27–0.86, P = 0.02).
This large series of TUR-P RP patients demonstrated that RP could be safely performed in patients with history of TUR-P without compromising oncological results. However, functional outcomes were worse for patients with previous TUR-P.
In this work, we consider a gauge R & R study in which a part measured in production is randomly placed in the measuring device. In assessing a measurement system, one does not want a possible ...within-part variation included in the estimated gauge variation and we propose a way to eliminate it. We consider a pellet measurement system and demonstrate the benefits of eliminating within-part variation in its assessment.

Abstract Context The European Association of Urology (EAU) Guidelines Office has set up a guideline working panel to analyse the scientific evidence published in the world literature on lasers in ...urologic practice. Objective Review the physical background and physiologic and technical aspects of the use of lasers in urology, as well as current clinical results from these new and evolving technologies, together with recommendations for the application of lasers in urology. The primary objective of this structured presentation of the current evidence base in this area is to assist clinicians in making informed choices regarding the use of lasers in their practice. Evidence acquisition Structured literature searches using an expert consultant were designed for each section of this document. Searches were carried out in the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Medline and Embase on the Dialog/DataStar platform. The controlled terminology of the respective databases was used, and both Medical Subject Headings and EMTREE were analysed for relevant entry terms. One Cochrane review was identified. Evidence synthesis Depending on the date of publication, the evidence for different laser treatments is heterogeneous. The available evidence allows treatments to be classified as safe alternatives for the treatment of bladder outlet obstruction in different clinical scenarios, such as refractory urinary retention, anticoagulation, and antiplatelet medication. Laser treatment for bladder cancer should only be used in a clinical trial setting or for patients who are not suitable for conventional treatment due to comorbidities or other complications. For the treatment of urinary stones and retrograde endoureterotomy, lasers provide a standard tool to augment the endourologic procedure. Conclusions In benign prostatic obstruction (BPO), laser vaporisation, resection, or enucleation are alternative treatment options. The standard treatment for BPO remains transurethral resection of the prostate for small to moderate size prostates and open prostatectomy for large prostates. Laser energy is an optimal treatment method for disintegrating urinary stones. The use of lasers to treat bladder tumours and in laparoscopy remains investigational.
