    Detecting coastal urbanization and land use change in Southern Turkey

    One of the most important needs in contemporary landscape planning is quantitative land use/land cover (LU/LC) change information. The reason a strong emphasis is placed on landscape change information is that it serves as an ecological and geographical basis for preparing and implementing development plans in a more sustainable manner. Multi-temporal analysis of LU/LC changes on the Eastern Mediterranean coast of Turkey revealed that there is a marked preference for these areas primarily for building development. This paper demonstrates a methodology that relies on quantitative analysis techniques for assessing spatiotemporal changes in LU/LC in the case of the eastern Mediterranean coast of Turkey. In this respect, satellite image datasets (SPOT panchromatic, Landsat TM) acquired in 1989, 1995, 2001 and 2007 were enhanced. Resulting images were classified and compared to detect coastal urbanization and development trends.  Post-classification change analyses were employed to quantify land cover conversions in three periods from 1985 to 1995, from 1995 to 2001 and from 2001 to 2007. This paper demonstrated that urban, agriculture and shrublands changed rapidly in this part of the Mediterranean coast

    Change detection in Southern Turkey using normalized difference vegetation index (NDVI)

    This study analyzed landscape changes in the Mediterranean using remotely sensed satellite images. Bitemporal Thematic Mapper (TM) scenes of Erdemli (Southern Turkey) acquired by Landsat satellites were analyzed to detect landscape changes in the study area, which supports a mosaic of landscapes from coastline to altitudes over tree line. Visible and near infrared bands (i.e. bands 3 and 4) of the near-anniversary (August) images from 1984 and 2006 were used to derive Normalized Difference Vegetation Index (NDVI) images. NDVI images for the earlier and later dates were analyzed. ASTER and Quickbird images, topographic maps, forest stand maps were used as ancillary data. Spatial distribution of change is mapped and interpreted. Results showed that forest regeneration took place especially in upper lands, while deforestation occurred at lower altitudes in relatively smaller patches in close proximity to the coast and to the roads.

    peer reviewedAllogeneic hematopoietic stem cell transplantation (HSCT) is the gold standard curative therapy for infants and children with many inborn errors of immunity (IEI), but adolescents and adults with IEI are rarely referred for transplant. Lack of published HSCT outcome data outside small, single-center studies and perceived high risk of transplant-related mortality have delayed the adoption of HSCT for IEI patients presenting or developing significant organ damage later in life. This large retrospective, multicenter HSCT outcome study reports on 329 IEI patients (age range, 15-62.5 years at HSCT). Patients underwent first HSCT between 2000 and 2019. Primary endpoints were overall survival (OS) and event-free survival (EFS). We also evaluated the influence of IEI-subgroup and IEI-specific risk factors at HSCT, including infections, bronchiectasis, colitis, malignancy, inflammatory lung disease, splenectomy, hepatic dysfunction, and systemic immunosuppression. At a median follow-up of 44.3 months, the estimated OS at 1 and 5 years post-HSCT for all patients was 78% and 71%, and EFS was 65% and 62%, respectively, with low rates of severe acute (8%) or extensive chronic (7%) graft-versus-host disease. On univariate analysis, OS and EFS were inferior in patients with primary antibody deficiency, bronchiectasis, prior splenectomy, hepatic comorbidity, and higher hematopoietic cell transplant comorbidity index scores. On multivariable analysis, EFS was inferior in those with a higher number of IEI-associated complications. Neither age nor donor had a significant effect on OS or EFS. We have identified age-independent risk factors for adverse outcome, providing much needed evidence to identify which patients are most likely to benefit from HSCT

    Bu çalışmada, Van Gölü Güney kıyı bölgesinde alanın doğal ve sosyo-kültürel peyzaj özellikleri ile biyofiziksel peyzaj özelliklerini bir bütün olarak ele alıp yerleşime uygunluk tespitinde yardımcı olabilecek bir model oluşturulması amaçlanmıştır. Bu kapsamda Van Gölü Güney kıyı bölgesi ve yakın çevresinde yerleşim uygunluğu ve göl görünürlük haritasının üretilmesi üzere uzaktan algılama ve coğrafi bilgi sistemleri araçlarından yararlanmıştır. Araştırma sonucunda alanını yerleşim uygunluklarına göre değerlendirme, yerleşim uygunlukları ile göl manzarası varlığına göre değerlendirme ve yerleşim uygunlukları ile seçilmiş bakı noktalarının uzman görüşleri sonuçlarına göre değerlendirmeler gerçekleştirilmiştir. Ortaya çıkan haritalar, veriler, bilgiler ve öneriler; doğal ve kültürel değerler açısından zengin olan Van Gölü'nün Güney kıyıları ve yakın çevresinde alan kullanım planlamaları ve önemli bir göl peyzajı niteliğindeki alanın yüksek değer taşıyan görsel kaynaklarının korunması için temel altlık durumunda olabilecektirThe present study was conducted with aims to create a model through visual analysis approaches for the southern coastal areas of the Van Lake that could aid in settlement suitability assessments, taking into consideration the socio-cultural and biophysical landscape properties of the region as a whole. With respect to this scope, remote sensing and geographical information tools were employed to create settlement suitability and lake visibility maps of the southern coastal areas of the lake. Assessments were made for settlement suitability of the lake coastal zones, for settlement suitability and lake view, and for settlement suitability and selected points of orientation along with expert opinions. Resulting maps, data, information and suggestions of this study may constitute a basic database for settlement planning of coastal zones and close surroundings of the Van Lake, and for preservation of visual aspects of lake landscape
