ABSTRACT Decisions regarding maintenance discipline have begun to change due to developments in the industrial field. Issues such as equipment condition monitoring, remaining useful life estimation, and maintenance planning have become essential business operations. In this study, predictive maintenance models were developed to prevent labor and economic losses caused by excessive and unnecessary maintenance and the remaining useful life estimated. NASA's Turbofan Engine Degradation Simulation Dataset helped to produce the predictive maintenance model and to validate models. The predictive maintenance model utilized five different machine learning methods in regression type and two different deep learning methods in classification type. Models designed using two other cross-validation methods and a variety of intelligent algorithms have assisted in determining the best outcome for the dataset under consideration. The analyzes and comparisons showed that Stacking Ensemble Learning and Convolutional Neural Network methods provided high performance for the preferred dataset. Models were compared based on accuracy and performance metrics, and the Stacking Ensemble Learning approach produced the most optimal result for the dataset applied.

Indoor and outdoor radon measurements at lung cancer patients’ homes in the dwellings of Rize Province in Turkey
No full textAkbulut Ozen, Songul/0000-0001-8025-2141In this study, indoor and outdoor radon (Rn-222) surveys were carried out in the summer and winter seasons in homes of one hundred lung cancer patients in the year 2013-2014. the aim was to investigate the relationship between radon and cancer patients. Lung cancer patients completed a questionnaire concerning their living environment, various physical parameters and living habits. Pearson correlation and t tests revealed no meaningful results between radon concentrations, on one hand, and environmental and personal living habits, on the other hand. Consequently, the BEIR VI model was adapted and Rn-222 exposure was estimated to be responsible for about 12% of the lung cancer incidences in the winter season and around 5% in the summer season in the Rize Province. However, due to the limited number of data and numerous parameters that could lead to lung cancer, the estimations done with the model should be taken very lightly. the annual effective doses due to inhalation of indoor and outdoor Rn-222 were estimated to be, respectively, 1.43 and 0.94 mSv y(-1). the indoor and outdoor annual effective doses were, respectively, close and below the world annual effective dose (1.3 mSv y(-1)). At the district level, the indoor annual effective dose equivalent in the A degrees yidere district was 4.52 mSv y(-1), which was 3.5 times greater than the world average. the number of patients in the majority of the houses in this district was more than one.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112S652]; Recep Tayyip Erdogan University Academic Research Projects UnitRecep Tayyip Erdogan University [2013.102.01.3]This work was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) with project number 112S652 and by the Recep Tayyip Erdogan University Academic Research Projects Unit with project number 2013.102.01.3. the authors would like to thank Prof. Dr. Orhan Karsli from Recep Tayyip Erdog. an University, Department of Geological Engineering, for the geological map of Rize

The Role Of Audit Committee In Achieving Auditing Effectiveness: A Study On External Auditing Firms
No full textMuhasebe denetiminin etkin olarak yapılmadığını, dünyada yaşanan birçok şirket yolsuzlukları ve hileli finansal raporlama uygulamaları göstermiştir. Bu durum finansal raporlama yapan ve bu raporları denetleyen kişilerin sorumluluklarını yeterince yerine getirmediklerini göstermiştir. Bu çalışma, muhasebe denetiminin etkin olarak uygulanabilmesinde denetim komitesinin rolünü ortaya koyarak bu alandaki bilgi boşluğunu doldurmayı amaçlamaktadır. Bunun için ülkemizde SPK’ya bağlı bağımsız denetim faaliyeti yapan firmalar arasından borsaya kayıtlı şirketleri denetleyen firmalar seçilmiştir. Denetimden sorumlu komitelerin bu firmaların etkinliklerine ne derece katkı sağladıklarını belirlemek için bir uygulama yapılmış ve sonuçlar değerlendirilmiştir.
Uygulamada yüz yüze anket yöntemi kullanılmıştır. Anket formundaki soruların belirlenmesinde ilgili literatür ve SPK’nın “ Seri X, No: 22 Sermaye Piyasasında Bağımsız Denetim Standartları Hakkında Tebliğ “ temel alınmıştır. Toplanan verilerin analizi üç aşamada gerçekleştirilmiştir. İlk önce araştırmayla ilgili tanımlayıcı istatistikler sunulmuştur. Daha sonra anket verilerinin büyük bir kısmına faktör analizi uygulanmıştır. Son aşamada ise elde edilen faktörler ve diğer bağımsız değişkenler kullanılarak regresyon analizi yapılmış ve araştırmanın amacına yönelik hipotezler test edilmiştir. Ulaşılan sonuçlar öz olarak şöyle belirtilebilir: Denetimden sorumlu komite işletmede iç kontrol sistemi yoksa bunun tesis edilmesini, iç denetim birimi yoksa bunun kurulmasını zorlamakta ve bunların sağlıklı işlemesini temin etmektedir. Bunun yanında yönetim, yönetim kurulu, iç denetçi ve bağımsız denetçiler arasında köprü görevi görmektedir. Bağımsız denetçinin bağımsızlığını güçlendirmekte ve bağımsız denetimin etkinliğini artırmaktadır. Ayrıca işletmenin karşılaşabileceği riskler konusunda da uyarı görevi görmektedir.auditing has not been done effectively. This has shown that people who do financial reporting and audit this reports have not fulfilled their responsibilities. This study aims to fill the lack of information on this field by showing the role of audit committee in the effective implementation of auditing. For this purpose firms which audit stock exchange registered companies are chosen among the external auditing firms which are members of SPK. A practice has been carried out to determine the extent of contribution of committees responsible for auditing to these firms and the results have been evaluated.
In this practice, person to person questionnaire method is chosen. The relevant literature and SPK’s “ Serie X, No: 22 Notice about Capital Market External Auditing Standarts.” is the basis for the questionnaire guestions. The analysis of the collected data is carried out in there stages. First descpriptive statistics about the research is presented. Next factor analysis is performed on a major part of the findings. At the last stage regression analysis is done with acquired factors and other independent variables and the hypotehesis of the study are tested. Results can be summarised as follows: Committee responsible for auditing enforces the establisment of an internal control system and internal auditing unit if there aren’t any and assures the proper function of these. Moreover it functions as a bridge between management, board of directors, internal auditor and external auditor. It reinforces the indepence of the external auditor and increases the effectiveness of external auditing. Also functions as warning mechanism for the risks the company may come across
