Authors: USLU Abdullah 
Published: December 2018

Bu
çalışma, konaklama işletmelerine gelen müşteriler ile çalışanlar arasındaki
bağların neler olduğunu belirlemek amacıyla gerçekleştirilmiştir. Çalışma
sonucunda ortaya çıkan müşteri-çalışan bağı boyutlarının, demografik
değişkenlere ve kullanım davranışına göre değişip değişmediği incelenecek
ayrıca kişilerarası kurulan bağların müşteriler tarafından ne düzeyde
algılandıkları da belirlenmeye çalışılacaktır. Araştırmanın
evrenini Fethiye’yi ziyaret eden İngiliz turistler oluşturmaktadır. Bu bağlamda
825 İngiliz turiste anket yapılmıştır. Elde
edilen sonuçlara göre konaklama işletmelerinde müşteri-çalışan arasında kurulan
bağların; aşinalık, arkadaşlık, umursama, uyum ve güven boyutlarından oluştuğu
tespit edilmiştir. Müşterilerin cinsiyet, müşteri-çalışan bağ seviyesi, tesise
geliş sayısı, yaşları, eğitim seviyeleri, hane halkı aylık gelirleri, seyahati
satın alma yöntemleri ve konaklama sürelerine göre müşteri-çalışan bağı
boyutlarını farklı algıladıkları yine bu boyutların memnuniyet üzerindeki etkisinin
olduğu belirlenmiştir.
SURİYE KRİZİ SONRASI TÜRKİYE’DEKİ SIĞINMACILARIN VE GÖÇMENLERİN EĞİTİMİ: GEÇMİŞ, BUGÜN VE GELECEK PERSPEKTİFLERİ

Published: December 2018

Cumhuriyetin
kuruluşundan beri kriz bölgelerinden Türkiye’ye dönemsel olarak göç akını
olmaktadır. Bulgaristan’daki komünist rejimin baskısıyla 1989’da 300 binin
üzerinde Türk ve Pomak, Saddam Hüseyin’in Kürtlere yönelik katliamları
sonucunda ise yarım milyon Kürt Türkiye’ye göç etmişti. Son olarak Türkiye,
bugün sayları 3,5 milyona varan Suriyeli sığınmacıya “açık kapı’’ politikası
uyguladı. Bu rakam ülkesi dışına göç eden Suriyelilerin büyük kısmını
oluşturuyordu. Göçlerin
gerek transit göç, gerekse kalıcı göç alması, eğitimde göçmenlere yönelik
politika geliştirme zorunluluğu doğurmuştur. Türkiye, çoğunluğu Suriyelilerden
oluşan fakat Suriyelilerin yanı sıra, Afganistan, Irak, İran ve Pakistan başta
olmak üzere 300 binin üzerinde sığınmacıya ev sahipliği yapmaktadır. İlk yıllarında
Suriye’deki iç savaşın kısa süreceği ve Suriyeli göçmenlerin ülkelerine
gidecekleri ile ilgili yaygın kanaat kısa vadeli planlar yapılmasına neden
olmuştu. Türkiye’nin
bulunduğu konum itibarıyla bölgesel krizlerle birlikte dönemsel olarak göç akınına
uğrayacağı aşikâr bir gerçektir. Göç edenlerin büyük bir kısmının çocuk ve genç
olması göç yönetiminde fırsatlar oluşturduğu gibi riskleri de barındırmaktadır.
Kültürel farklılıkları kabullenmenin uyum sürecinde yapıcı adımlar atmanın ve
toplumsal uyum sağlayabilmenin en önemli adımlarından biri eğitimdir. Türkiye krizlerle birlikte gündeme gelen göç
politikaları yerine göçmenler için uzun, kalıcı ve sürdürülebilir eğitim
politikaları geliştirmek durumundadır. Bu
makale, 2011 Suriye krizi ile birlikte siyasilerin ve bürokratların,
göçmenlerin eğitimleri hususundaki söylemlerini ve [1]eğitimde
bugüne kadar yapılan hukuki ve idari değişiklikleri ele almakta ve Türkiye’de
yaşayan göçmenlerin mevcut durumlarını, eğitimde yaşadıkları sorunları ve bu
sorunlara getirilen çözüm önerilerini de içeren perspektif sunmaktadır.

Aim. Lipoprotein(a) [Lp(a)] and low molecular weight (LMW) apolipoprotein(a) [apo(a)] phenotype are risk factors of сoronary heart disease and stroke. Data about the role of Lp(a) and phenotypes apo(a) in the development of lower extremity artery disease (LEAD) is scarce. The aim of our study was to assess the association of Lp(a), apo(a) phenotypes and autoantibodies to apolipoprotein B100 (apoB100) lipoproteins with LEAD.Materials and methods. The study included 622 patients (386 male and 236 female, average age 61±12 years), examined in the Department of Atherosclerosis of National Medical Research Center of Cardiology. Patients were divided into 2 groups: the main group included 284 patients with LEAD, 338 patients without significant atherosclerosis of coronary, carotid and lower limbs arteries formed the control group. LEAD was diagnosed as atherosclerotic lesions with at least one stenosis of low limb artery ≥50 % and ankle­brachial index ≤0.9. The concentration of Lp(a), lipids was measured in blood serum of all the patients, level of autoantibodies to apoB100 lipoproteins was measured in 247 patients, and apo(a) phenotypes were determined in 389 patients.Results.Patients with LEAD were older, were more frequently male, and had a greater prevalence of risk factors including hypertension, type 2 diabetes, smoking than the control group patients (p<0.001 in all the cases). The level of Lp(a) was significantly higher in the main group compared to control group: 35 [14; 67] mg / dl vs. 14 [5; 32] mg / dl, p<0,001. ROC analysis demonstrated that the level of Lp(a) ≥26 mg / dl was associated with LEAD (sensitivity 61 %, specificity 70 %). The prevalence of Lp(a) ≥26 mg / dl and LMW apo(a) phenotype were higher in the main group in comparison with the control group: 61 % vs. 30 % and 48 % vs. 26 % respectively (p<0.001 in the both cases). The odds ratio of LEAD in the presence of Lp(a) ≥26 mg / dl was 3.7 (95 % confidence interval (CI), 2.6–5.1, p<0.001) and in the presence of LMW apo(a) phenotype was 2.6 (95 % CI, 1.7–4.0, p<0.001). In logistic regression analysis adjusted for age, sex, hypertension, smoking, diabetes, both Lp(a) and LMW apo(a) phenotype were independent predictors of LEAD when included separately. The level of IgM autoantibodies to Lp(a) was significantly higher in the control group compared to the patients with LEAD (p=0.01). Concentration of IgG autoantobodies to Lp(a) and LDL in the plasma did not differ essentially in the both groups.Conclusion.The level of Lp(a) ≥26 mg / dl and LMW apo(a) phenotype are independent predictors of LEAD, whereas the contribution of autoantobodies to Lp(a) in LEAD development is controversial.

Aim.To investigate the difference in characteristics of patients admitted to the Tomsk National Research Medical Center with a diagnosis of heart failure (HF) in 2002 and 2016.Methods. Medical charts of all patients hospitalised in a single centre, with a diagnosis of HF, were included. Two three‑month periods were compared from January 2002 (n=210) and January 2016 (n=378).Results.Fewer patients with HF had symptoms or required diuretics in 2016 (63 % vs 98,6 %, p<0.001). During this period the percentage of patients with HFpEF increased from 58.6 % to 74.1 % (p=0.001) whereas those with HFrEF remained similar (19.5 % vs 14.0 %, p=0.1) and those with HFmrEF declined (21.9 % vs 11,9 %, p=0.007). In patients with HFrEF the prescription of ACEi / ARB remained similar (80.4 vs 88 %, p=0.3), beta‑blockers increased from 68 to 85 % (p=0.03) and aldosterone antagonists from 9.7 to 49 % (p<0.001).Conclusion.Prescription rates for prognostic medications in HFrEF improved in 2016. The substantial percentage of patients diagnosed with HFpEF without symptoms or diuretic raises the question of whether a diagnosis of HF was appropriate in some cases.

A REPRESENTAÇÃO DO COMBATENTE NA FICÇÃO DE ANTÓNIO LOBO ANTUNES: FANTASMAS DE UM PORTUGAL ANTIÉPICO
Authors: Von Pfeil Rommel Leonardo 
Published: December 2018

Resumo O presente artigo analisa a representação antiépica do combatente português em três romances do escritor português António Lobo Antunes, sendo eles: Memória de elefante (1979), Os cus de Judas (1979) e Conhecimento do inferno (1980). A literatura portuguesa que tematiza a Guerra Colonial destaca-se por apresentar um discurso contrário ao modelo camoniano e ao seu discurso laudatório, buscando reinterpretar o sentido da história contemporânea de Portugal. Para discutir o tema, usaram-se os teóricos Bakhtin (1998) e Anna Kalewska (2000). Demonstrou-se, assim, que a ficção de Lobo Antunes constitui-se em um discurso antiépico, que causa uma ruptura na identidade e no imaginário coletivo nacional ao questionar, através da figura do combatente da Guerra Colonial, o discurso épico de fundação de toda a mitologia imperial lusitana, o que configura uma das suas marcas na história literária portuguesa. Palavras-chave: Antiépico; anti-herói; Guerra Colonial; identidade nacional; António Lobo Antunes

Acute aortic dissection type 3 was occurred in 10 patients and two of them were complicated with rupture into the left pleural cavity. 10 patients with chronic aortic dissection type bunderwent operations and one of them was complicated with rupture into the left pleural cavity. Among 8 operated patients due to chronic aneurysms of descending part of thoracic aorta, 4 patients were manifested with symptoms of hemothorax. In 3 patients with aortic dissection type 1 in long-term period, endovascular stent-grafting was performed concerning with the dilatation of descending thoracic aorta and patent false lumen. During in-hospital and long-term periods immediate clinical results, serious clinical complications and long-term survival were compared.Results: technical success of endovascular stent-grafting was achieved in 100 % of cases. In-hospital mortality was 4 (14,2 %) and 30-day mortality was 3 (10,7 %). Events of paraplegia, TIA (Transient Ischemic Attack), prosthetic infection were not found in our research. Two clinical occurrences of vascular approach site complication were found; one case of endoleak type 1 and stent-graft dislocation which required repeated endovascular stent-grafting and one case of endoleak type 2 which was performed subclaviancarotid bypass and ligation of left subclavian artery. Prolong intubation was needed in 5 patients (18,5 %).conclusion: Endovascular stent-grafting in dissections and atherosclerotic aneurysms of descending part of thoracic aorta contributes good immediate clinical results associating with less quantity of serious complications.
Implementation of Codigestion and sludge management system in Portugal
Authors: Di Berardino Santino 
Published: December 2018

Anaerobic digestion is carried out to stabilize biosolids so that it is acceptable for land disposal. Although no precise definition A solution based on sludge and Olive oil mill effluent (OME) codigestion, coupled with a management plan, has been implemented, to treat and dispose safely, the mixed residues, into the natural forest and agricultural land.
The mixture of up to 25 % OME to the sludge improved anaerobic degradation of phenols and fats. High density fats compounds, presents in OME, enhanced aggregation, settling and acetoclastic activity of anaerobic sludge. The full scale unit, obtained by modification of a cold digester, allowed to set-up a low capital cost system. The system produced large quantity of biogas and electric energy.
Anaerobic degradation of the mixture improved fertilizing properties, making feasible land application of the digested mixture. Regional plan based in Geographical Information System (GIS) selected 800 ha of adequate land area for application near the WWTP. The experience is technically and economically successful. Main incomes are provided by energy use and OME charge. Sludge application in local agriculture does generate any income, but eliminated landfill costs and reduced transportation costs.
Towards model predictive control: online predictions of ammonium and nitrate removal by using a stochastic ASM
Authors: Stentoft Peter Alexander , Munk-Nielsen Thomas , Vezzaro Luca , Madsen Henrik , Mikkelsen Peter Steen , Møller Jan Kloppenborg 
Published: December 2018

Abstract
Online model predictive control (MPC) of water resource recovery facilities (WRRFs) requires simple and fast models to improve the operation of energy-demanding processes, such as aeration for nitrogen removal. Selected elements of the activated sludge model number 1 modelling framework for ammonium and nitrate removal were included in discretely observed stochastic differential equations in which online data are assimilated to update the model states. This allows us to produce model-based predictions including uncertainty in real time while it also reduces the number of parameters compared to many detailed models. It introduces only a small residual error when used to predict ammonium and nitrate concentrations in a small recirculating WRRF facility. The error when predicting 2 min ahead corresponds to the uncertainty from the sensors. When predicting 24 hours ahead the mean relative residual error increases to ∼10% and ∼20% for ammonium and nitrate concentrations respectively. Consequently this is considered a first step towards stochastic MPC of the aeration process. Ultimately this can reduce electricity demand and cost for water resource recovery, allowing the prioritization of aeration during periods of cheaper electricity.
Novel advanced porous concrete in constructed wetlands: preparation, characterization and application in urban storm runoff treatment
Authors: Tang Van Tai , Pakshirajan Kannan 
Published: December 2018

Abstract
Common porous concrete templates (CPCT) and advanced porous concrete templates (APCT) were employed in this study to construct wetlands for their applications in pollutant removal from storm runoff. The planting ability of the concrete was investigated by growing Festuca elata plants in them. Strength of the porous concrete (7.21 ± 0.19 Mpa) decreased by 1.8 and 4.9% over a period of six and 12 months, respectively, due to its immersion in lake water. The height and weight of Festuca elata grass growth on the porous concrete were observed to be 12.6–16.9 mm and 63.4–95.4 mg, respectively, after a duration of one month. Advanced porous concrete template based constructed wetland (APCT-CW) showed better removal of chemical oxygen demand (COD) (49.6%), total suspended solids (TSS) (58.9), NH3-N (52.4%), total nitrogen (TN) (47.7%) and total phosphorus (TP) (45.5%) in storm water, when compared with the common porous concrete template based constructed wetland (CPCT-CW) with 20.6, 29.8, 30.1, 35.4 and 26.9%, respectively. The removal of Pb, Ni, Zn by the CPCT-CW unit were 28.9, 33.3 and 42.3%, respectively, whereas these were 51.1, 62.5 and 53.8%, respectively, with the APCT-CW unit. These results demonstrate that the advanced porous concrete template in constructed wetland could be employed successfully for the removal of pollutants from urban storm water runoff.
The chemistry of Cr(VI) adsorption on to poly(p-phenylenediamine) adsorbent

Published: December 2018

Abstract
Water pollution due to industrial processes has necessitated and spurred robust research into the development of adsorbent materials for remediation. Polyphenylenediamines (PPD) have attracted significant attention because of their dual cationic and redox properties. They are able to reduce Cr(VI) to Cr(III) in solution. Interrogation of the chemical processes involved in the Cr(VI) adsorption on para-PPD was primarily by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectroscopy. It was confirmed that the underlying oxidation of the amino groups to imines during the reduction of Cr(VI) to Cr(III) was irreversible. This process occurred at both acidic and alkaline conditions. Reduction was accompanied by Cr(III) chelation on the adsorbent surface. Further, regeneration with dilute aqueous NaOH and HCl extended the polymer's adsorptive capacity beyond exhaustion of its redox potentials.
