Business analytics in industry 4.0: a systematic review

Recently, the term “Industry 4.0” has emerged to characterize several Information Technology and Communication (ICT) adoptions in production processes (e.g., Internet-of-Things, implementation of digital production support information technologies). Business Analytics is often used within the Industry 4.0, thus incorporating its data intelligence (e.g., statistical analysis, predictive modelling, optimization) expert system component. In this paper, we perform a Systematic Literature Review (SLR) on the usage of Business Analytics within the Industry 4.0 concept, covering a selection of 169 papers obtained from six major scientific publication sources from 2010 to March 2020. The selected papers were first classified in three major types, namely, Practical Application, Reviews and Framework Proposal. Then, we analysed with more detail the practical application studies which were further divided into three main categories of the Gartner analytical maturity model, Descriptive Analytics, Predictive Analytics and Prescriptive Analytics. In particular, we characterized the distinct analytics studies in terms of the industry application and data context used, impact (in terms of their Technology Readiness Level) and selected data modelling method. Our SLR analysis provides a mapping of how data-based Industry 4.0 expert systems are currently used, disclosing also research gaps and future research opportunities.The work of P.

Evaluation of patulin in commercial baby foods by solid phase extraction and liquid chromatography PDA detection

A simple, reliable, and rapid RP-LC method has been developed for the determination of patulin in commercial baby foods from Turkish markets. Solid phase extraction and liquid chromatography with photodiode array detection technique were used for the analysis of patulin in samples. Linearity was obtained in different concentration ranges between 0.001 and 0.050 ?g/l. The recovery rates for patulin ranged from 92.85% to 100.45% with a coefficient of variation less than 3.0%. LOD and LOQ of the method were found to be 9.66 × 10-6 and 2.93 × 10-5 ?g/ml, respectively. The proposed method has been extensively validated in accordance with ICH guidelines. It can be used by routine analysis laboratories within a short time of analysis. All of the detected samples containing patulin were below the level suggested by the World Health Organization

Re: Long-term results of permanent memotherm urethral stent in the treatment of recurrent bulbar urethral strictures

Purpose: To evaluate the long term outcomes of permanent Memotherm urethral stent in the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty patients who underwent permanent Memotherm urethral stent implantation due to recurrent bulbar urethral stricture following previous unsuccessful surgical procedure from 1996 to 2002 were included in the study. Long-term outcomes of the patients were evaluated. Results: The overall success rate was 87.5% at the end of the tenth year. There was discomfort in implantation area in eight patients about 1 month following the procedure. These patients were treated with alpha-blocker and anti-inflammatory drugs. Stone formation was observed at the urethral stent implantation area in two patients. Post-void dripping has been observed in 15 patients up to the postoperative 3rd month. Stress urinary incontinence was observed in a patient with a 1-year follow-up. Partial stent migration was observed in two patients. None of the patients experienced pain during erection. Conclusion: Memotherm urethral stent is a minimal invasive surgical procedure which can be safely and effectively used in patients with recurrent urethral stricture

Venous port catheter implantation: An experience of 130 cases in general surgery [Venöz Port Katater implantasyonu: 130 Olguluk Genel Cerrahi Deneyimi]

Objective: Totally placed venous catheters for long-term chemotherapy, total parenteral nutrition and fluid replacement in oncologic patients improve quality of life. However, despite their usefulness, serious complications such as thrombosis, infection, perforation, pneumothorax, rupture, displacement and fistulization may occur in the placement and management of these catheters. The aim of our retrospective study was to share our clinical experience with the readers and to evaluate the early and late complications in the light of the literature. Material and Methods: Between February 2008 and December 2014, clinical and demographic data of 130 cancer patients with total implantable permanent venous port catheter in Izmir Bozyaka Training and Research Hospital 3rd General Surgery Clinic were retrospectively reviewed. Results: A total of 130 patients had a port catheter for chemotherapy. The average age of the patients is 54.1 years, 75 is female and 55 is female. All patients had malignancy. Port catheters were placed for disease chemotherapy. Complications included pneumothorax in one patient, malposition in one patient, infection at the port site in 8 patients, skin necrosis in one patient, and venous thrombosis in one patient. Conclusion: The use of central venules with percutaneous technique for permanent venous port catheter insertion is a technique that can be applied safely in experienced hands, has low complication rate, high success rate and is very comfortable for patients. © Copyright 2017 by Gazi University Medical Faculty
