Yalın hizmet işlemleri uygulaması: Türk bankacılık endüstrisinden bir örnek olay analizi

Öz (Tr): Bu çalışmada yalın yönetim ve bankacılık uygulaması ele alınmaktadır. Yalın yönetimin imalat ortamında anlamlı çıktılar sağlayacak şekilde atıl kaynakları ortadan kaldırmasından dolayı hizmet endüstrisi de yalın uygulamalarına odaklanmaya başlamıştır. Buradan hareketle, bu çalışma, özellikle yalın araçları kullanılarak Türkiye'de bankacılık sektöründeki atıl kullanımın ortadan kaldırılması anlamında öncü çalışmalardan birisi olmaktadır. Bu amaçla devlet bankalarından birisinin Ege Bölgesi'ndeki şubelerinden birisi pilot uygulama alanı olarak seçildi ve bu pilot çalışma alanında müşteriler, banka müşteri temsilcileri ve operasyonlar üzerinde gözlemler yapılarak veri toplanmıştır. Toplanan veriler analiz edildikten sonar gereksiz işlemlerin ortadan kaldırılmasına bağlı olarak bazı iyileştirmeler önerilmektedir. Elde edilen sonuçlar bankacılık sektörü için; katma değerli iş elemanlarına yoğunlaşmak suretiyle yapılan basit iyileştirmelerle anlamlı sonuçlara ulaşılabileceğini göstermektedir. Elde edilen sonuçlar bankanın diğer şubelerine de aynı şekilde uygulanabilmektedir. Öz (Yabancı): This paper describes lean management and its application in banking industry. Since lean management eliminates waste effectively in manufacturing environment with significant outputs, service industry has started to focus on lean implementations. In this sense, this paper is a pioneer especially for banking in service sector in Turkey to eliminate waste by means of lean methods. For this reason, a branch of a nationwide state bank in Aegean region was selected as pilot to collect data by observing customers, employee and operations. After analyzing the collected data, some improvements due to eliminations of unnecessary operations were offered. Our results show that significant improvements in banking sector are easy to achieve just by focusing value adding operations. Obtained results are also valid for other branches of the bank

Effects of immunosuppressive drugs on COVID-19 severity in patients with autoimmune hepatitis

Background: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). Patients and methods: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. Results: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. Conclusion: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.Fil: Efe, Cumali.

Twenty-three unsolved problems in hydrology (UPH) – a community perspective

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through on-line media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focussed on process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come

Diagnostic value of S100P, IMP3, Maspin, and pVHL in the differantial diagnosis of pancreatic ductal adenocarcinoma and normal/chronic pancreatitis in fine needle aspiration biopsy

Introduction: Differentiation between pancreatic ductal adenocarcinoma (PDAC) from benign mimickers is a well-known problem in cytological materials. Recent studies incorporated biological markers into this question and some studies showed that expression of S100P, IMP3, and maspin as well as nonexpression of von Hippel-Lindau gene product (pVHL) were significantly correlated with PDAC. In this study, we aimed to investigate diagnostic value of maspin, IMP3, S100P, and pVHL immunostaining in fine needle aspiration biopsies (FNABs) of pancreatic lesions. Materials and Method: In all, 33 cases of FNAB cell blocks of PDAC and 34 cases of surgical non-neoplastic pancreas specimens which were retrieved from the archives slides from 2007 to 2011 were included in this study. All the cases were stained with maspin, IMP3, S100P, and pVHL. Expression patterns of markers were scored and compared with benign mimickers. Test performance of each antibody and possible antibody combinations were also evaluated. Results: The study was composed of 33 PDAC and 34 control cases (8 chronic pancreatitis, 3 mucinous cystic neoplasm, and 23 nontumoral pancreatic tissue of PDAC). Diagnostic sensitivity for malignancy in S100P, IMP3, and maspin was 84.8%, 81.8%, and 87.5%, respectively. Specificity of these three markers was 100%. Sensitivity and specificity of pVHL for detecting nontumoral pancreatic tissue were 100% and 81.8%, respectively. When maspin, IMP3, and S100P expression were used together as triple test, sensitivity was 62.5% and specificity 100%. However, when any two of each three markers were evaluated (triple test/dual response), sensitivity reached 93.8% and specificity 100%. Conclusion: We observed that dual response in triple test (positive staining with two of these three markers) of maspin, IMP3, and S100P immunocytochemistry is very sensitive and specific in differential diagnosis of PDA and non-neoplastic pancreatic lesions. pVHL may have an additional role, when triple assessment is not satisfactory
