    Objective: We used the results from the first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (20092019) and the first organized population-based screening program implemented in a county of Istanbul, Turkey, to assess the potential cost-effectiveness of a population-based mammography screening program in Turkey. Materials and Methods: Two screening strategies were compared: BMSP (includes three biennial screens for women between 40-69) and Turkish National Breast Cancer Registry Program (TNBCRP) which includes no organized population-based screening. Costs were estimated using direct data from the BMSP project and the reimbursement rates of Turkish Social Security Administration. The life-years saved by BMSP were estimated using the stage distribution observed with BMSP and TNBCRP. Results: A total of 67 women (out of 7234 screened women) were diagnosed with breast cancer in BMSP. The stage distribution for AJCC stages O, I, II, III, IV was 19.4%, 50.8%, 20.9%, 7.5%, 1.5% and 4.9%, 26.6%, 44.9%, 20.8%, 2.8% with BMSP and TNBCRP, respectively. The BMSP program is expected to save 279.46 life years over TNBCRP with an additional cost of 677.171,whichimpliesanincrementalcosteffectivenessratio(ICER)of 677.171, which implies an incremental cost-effectiveness ratio (ICER) of 2.423 per saved life year. Since the ICER is smaller than the Gross Demostic Product (GDP) per capita in Turkey ($ 10.515 in 2014), BMSP program is highly cost-effective and remains cost-effective in the sensitivity analysis. Conclusion: Mammography screening may change the stage distribution of breast cancer in Turkey. Furthermore, an organized population-based screening program may be cost-effective in Turkey and in other developing countries. More research is needed to better estimate life-years saved with screening and further validate the findings of our study.Roche Turkey; Breast Health Society of Turkey (MEMEDER); Clinical and Translational Science Award (CTSA) program, through the NIH National Center for Advancing Translational Sciences (NCATS)United States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Center for Advancing Translational Sciences (NCATS) [UL1TR000427]; NATIONAL CENTER FOR ADVANCING TRANSLATIONAL SCIENCESUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Center for Advancing Translational Sciences (NCATS) [UL1TR000427] Funding Source: NIH RePORTERThe study was funded by Roche Turkey and in part by the Breast Health Society of Turkey (MEMEDER).

    Fotoğrafta gerçeğin saptırılması ve yeni/başka gerçeklik arayışları

    ÖZET İnsanlık varoluşundan beri ‘gerçek’ dünya ile çevrelenmiş olmasına rağmen, hep kendi öznel gerçeğini oluşturmuş ve bu gerçeklikle yaşamıştır. Gerçeklik, her bireyin kendi bakış açısıyla oluşturduğu izlenimler aracılığıyla algılandığından, onu mutlak ve genel geçerli bir tanıma indirgemek ve ifade edebilmek olası değildir. Yaşamını anlamlandırma isteği, bireyi felsefi düşünmeye ve üretmeye iterken, yaratma dürtüsünün getirisi olan gerçeklik arayışları sanatla doğrudan ilişkilidir. Teknolojik gelişmeler doğrultusunda 19. yüzyılın ortalarında fotoğrafın devreye girmesi ile, görüntüler ve gerçeklik arasındaki ilişki bambaşka bir tartışma ortamına taşınır. Fotoğrafı, dış gerçekliği ‘tarafsız’ ve ‘birebir’ yeniden üretip çoğaltabilen bir araç olarak görmek ile, sanatsal anlatı dilini oluşturacak yaratıcı bir ifade biçimi olarak görmek arasındaki ikilem nedeniyle; bu karmaşık ilişki hiç bir zaman yalın ve net bir biçimde açıklanamaz. İnsanlık gün geçtikçe teknolojinin de hiç sorgulanmaksızın kullanılması sonucu, duyarsızlaşmaktadır. Sistem yavaş yavaş insan ve doğa arasına koyduğu mesafeyi artırırken toplumu dış dünya gerçekliğinden koparır. Gerçeklik arayışı ve sanatsal kaygı da, artık yalnızca geri kalan her şey gibi ‘tüketilmek’ için vardır. Dolayısıyla bugüne değin tanımlanmış tüm kavramların içi boşalır. Kitlesel iletişim araçları içi boşaltılmış anlamları yineleyerek, gerçeği unutturur ve toplumları kendilerine yabancılaştırır. Etrafımız bireysel olarak asla algılayamayacağımız kadar çok fotoğrafla donatılmış durumdadır. Bu fotoğraflar dünyanın gerçekliğiyle olan ilişkimizi dönüştürerek, yeni, yabancılaşmış bir “görme etiği” oluşturur. Platon’un Mağara Alegorisi’ne atıfla; koşullar değişmiş olsa bile, bizler hala Platon’un mağarasında oturmaya devam ediyoruz. Günümüzde birer ifade ve iletişim kurma biçimi olan fotoğraflar, görselliğimizi somutlaştırdığımız kişiye özel gerçeklik arayışlarıdır. Fotografik süreç, görünüşlerin birebir tasvirlerinin kaydedilmesinin ötesine geçen ve örtücünün kapanmasından sonra gerçekleşen bir gerçekliğe dönüşüyor.

Reality is through each individual’s own impressions, that’s the reason why it is not possible to reduce and render it to an absolute and de facto recognition. The desire to make sense out of his life pushes the individual into philosophical thinking and production; the urge to create comes about the search for reality which is also directly linked to or related to art. As a result of the technological developments in the middle of the 19th century, the introduction of the photograph brings out the relationship between images and reality to a completely different discussion environment. Due to the dilemma between seeing the photograph as a means to reproduce external reality ‘objectively’ and ‘as is’ or seeing it as a creative form of expression which is constituent of the artistic narrative language; the complex relationship can never simply and clearly be explained. Today photography is a form of expression and communication, through which we search for our own specific reality and embody our visuality. The infinite information access provided by the Internet and the means of the digital age provide endless freedom and opportunity for us to produce our own realities. The photographic process turns into an event and reality that goes beyond the recording of one-to-one descriptions of appearances and begins to take place after the shutter closes

    WOS: 000254501100010PubMed: 17999670Hepatitis A and E are enteric viral diseases that are characteristically found in developing countries. Sero-epidemiological data about both infections showed higher prevalence rates soon after the 1999 earthquakes in Duzce, Turkey. The aim of the present study was to evaluate the data 4 years after the earthquakes. The study group included 589 children (72.3% boys) who were between the ages of 6 months and 17 years (mean age 11.5 years). The children were separated into three groups: Group 1 (ages 6 months to 5.9 years), Group 2 (ages 6.0-12.9 years) and Group 3 (ages 13.0-17.0 years). Serum anti-hepatitis A virus IgG and anti-hepatitis E virus IgG were determined using commercial enzyme-linked immunosorbent assay kits. The data were tested for statistical significance with the chi(2)-test. The sero-prevalence rates of hepatitis A and E were 63.8% and 0.3%, respectively. The sero-prevalence rates of both hepatitis A and E increased with age, and there was no significant difference between the genders. Hepatitis A infection was associated with socio-economic condition, crowded living environment, and education level of the family (P < 0.01). Hepatitis A infection is still common, whereas hepatitis E infection appears to be relatively rare in paediatric age groups in Duzce, Turkey

    Simulation based design and fabrication of a PPy coated PDMS based pressure sensor

    Flexible sensors have attracted widespread attention because of their highly desired multifunctionality such as flexibility, high sensitivity, and large workable range in electronic skin or wearable health monitoring applications. Among these, piezoresistive pressure sensors are expected to deliver these functions in a stable fashion whilst being produced in a low cost and scalable manner. It is known that sensor performance directly depends on the 3D geometrical and material composition. In this study a flexible pressure sensor with a unique interconnected and porous geometry is designed and fabricated using a simulation based design approach and a two-step manufacturing technique. The substrate of the sensor is cast using Poly- dimethylsiloxane (PDMS) which is known for its mold-release properties and ability to replicate fine features with low shrinkage and excellent elastic properties. The 3D PDMS structures were prepared by mixing base solution and curing agent at a weight ratio of 10:1 following poured onto 3D printed molds and cured at 80 °C for over 2 h. The sensing capability of the composite material was achieved by the facile solution based dip coating method of polypyrrole (PPy) thin film onto the PDMS structure. The mechanical and electrical response of the proposed PPy coated PDMS sensor was characterized using compression tests via a multimeter setup integrated to Universal Testing Machine and a four-point probe measurement system. Micro-computed tomography characterizations were used to analyze the cast sensor’s geometrical features. Simulations were carried out using Finite Element Analysis software COMSOL Multiphysics. Both simulations and measurements demonstrate that the proposed sensor delivers a stable piezoresistive behavior with high sensitivity. The proposed production technique’s flexibility to produce sensors with complex 3D geometries combined with the tuning potential of the sensor’s sensitivity should prove useful for a wide range of applications with different desired pressure ranges
