ENVIRONMENTAL PERFORMANCES OF BALKAN COUNTRIES AND TURKEY: A COMPARISON THROUGH THE ENVIRONMENTAL PERFORMANCE INDEX
Sustainable development is a multidimensional concept relating to bothenvironmental and social issues. The concept of sustainable development is theresult of the growing awareness of the global links between mountingenvironmental problems, socio-economic issues to do with poverty and inequalityand concerns about a healthy future for humanity. There are various indicesworldwide focusing on assessing the environmental dimension of sustainability.These indices try to measure and compare the environmental performances of worldcountries. Since the 1992 Rio Earth Summit, governments are trying to demonstrateimproved environmental performance through quantitative metrics across a rangeof pollution control and natural resource management challenges.Environmental performance index (EPI) compiles environmental data of almost allof the world countries, therefore it is a useful tool to make cross-countrycomparisons. The purpose of this paper, after a literature review on the countryenvironmental performance and its indicators, is to compare the environmentalperformances of Balkan countries and Turkey through their EPI scores. Findingswill contribute future environmental policy decisions of these countries
A probabilistic analysis framework for malicious insider threats
Malicious insider threats are difficult to detect and to mitigate. Many approaches for explaining behaviour exist, but there is little work to relate them to formal approaches to insider threat detection. In this work we present a general formal framework to perform analysis for malicious insider threats, based on probabilistic modelling, verification, and synthesis techniques. The framework first identifies insiders' intention to perform an inside attack, using Bayesian networks, and in a second phase computes the probability of success for an inside attack by this actor, using probabilistic model checking

Determınatıon of suıtabılıty of douglas-fır (pseudotsuga menziesii (mirb.) franco) specıes for partıcleboard productıon
Bu çalışmada, hızlı büyüyen ağaç türlerinden biri olan ve Trabzon’un Maçka bölgesinde başarılı plantasyon sonuçları veren Douglas Göknarı (Pseudotsuga menziesii (Mirb.) Franco)’nın yonga levha üretimine uygunluğu araştırılmıştır. Üretilen levhaların fiziksel (şişme oranı, yoğunluk) ve mekanik özellikleri (eğilme direnci, yüzeye dik çekme direnci ve elastiklik modülü) belirlenmiştir. Pres sıcaklığı ile presleme süresinin ve levha yoğunluğunun yonga levha özellikleri üzerine etkileri araştırılmıştır. Elde edilen sonuçlar EN standartlarında öngörülen değerler ile karşılaştırılmıştır. Test sonuçlarına göre 0.70 g/cm3 yoğunlukta üretilen yonga levhalar EN standartlarında öngörülen minimum eğilme ve yüzeye dik çekme direnci ihtiyacını karşılamışlardır. Yoğunluğu 0.60 g/cm3 olan levhalar ise standartlarda öngörülen eğilme ve yüzeye dik çekme direnci değerlerine ulaşabilmek için 150 °C pres sıcaklığında ve 7 dakika presleme süresi kullanılarak üretilmelidir. Douglas Göknarı (Pseudotsuga menziesii (Mirb.) Franco)’ndan üretilen yonga levhaların şişme oranları standartlarda öngörülen değerlerden yüksek bulunmuştur. Bu nedenle bu levhaların kalınlığına şişme oranlarını azaltıcı ek bir çalışmanın yapılması gerektiği sonucuna ulaşılmıştır.In this study, Douglas-Fir (Pseudotsuga menziesii (Mirb.) Franco), one of the fast growing trees and planted succesfully in Maçka, Trabzon area was investigated for manufacturing particleboard. All panels were tested for physical property (thickness swelling (TS), density (D)) and mechanical properties (bending strength (BS), internal bond (IB), and modulus of elasticity (MOE)). The effects of press temperature, press time and board density on the some properties of particleboards were investigated. The results were compared with EN standard values. Results showed that Douglas-Fir particleboards produced at 0.70 g/cm3 density had the requirements of IB and BS. The particleboards which have 0.60 g/cm3 board density, needed 150 °C press temperature, 7 min. press time, respectively. In these production conditions, the particleboards had the required level of IB and BS according to the EN standards. But, TS values were higher than the required levels of the standard. For this reason, additional work is needed to improve the thickness swelling of Douglas-Fir particleboards
Análisis comparativo del impacto, de la segregación de los datos por género, en los protocolos de investigación de fisiología reproductiva y cardio-respiratoria
Es un hecho conocido que el dimorfismo sexual se presenta en la mayoría de las
especies animales. Las diferencias que esto conlleva, tienen una base genética que sustenta
características físicas propias de machos o hembras. Conocido esto, es evidente la necesidad de
determinar la incidencia genérica en el funcionamiento de cualquier organismo. Sin embargo, el
presente análisis, ha permitido comprobar que, la inclusión en la segregación de los resultados
por género en estudios de Bio-Medicina (clínicos y pre-clínicos) aún no es algo generalizado.
Para ello, se han revisado y combinado los resultados de un conjunto de estudios (fechados
entre 2011 y 2017) escogiéndose dos áreas (en cuyas fisio-patologías se acepte diferente grado
de impacto del género): aparato reproductivo y el sistema cardio-respiratorio. Los resultados
obtenidos confirman la necesidad de concienciar a la comunidad científica de la importancia de
la inclusión de la variable “género” en este tipo de estudios.It is a known fact that sexual dimorphism occurs in most animal species. The differences that this
entails have a genetic basis that supports physical characteristics of males or females. Once this
is known, the need to determine the generic incidence in the functioning of any organism is
evident. However, the present analysis has shown that inclusion in the segregation of results by
gender in Bio-Medicine studies (clinical and pre-clinical) is not yet widespread. For that, the
results of a series of studies (dated between 2011 and 2017) have been reviewed and combined,
choosing two areas (in whose physio-pathologies a different degree of gender impact is
accepted): reproductive system and the cardio-respiratory system. The results obtained confirm
the need to make the scientific community aware of the importance of including the gender
variable in this type of studies
Evaluation of clinical, diagnostic and treatment aspects in hydatid disease: analysis of an 8-year experience
Background & Objective: Echinococcosis is still a common health problem. The aim of this study was to discuss our 8-year data in terms of diagnosis, treatment and follow-up of cystic Echinococcosis.Methods: A total of 178 patients who had hydatid cyst were analyzed retrospectively from the hospital records. The diagnosis of hydatid cyst was based on clinical-serological and radiological findings. Treatment response was evaluated with clinical, radiological and serological findings.Results: A total of 178 medical records were evaluated; the male:female ratio was 0.73 and mean age 44.6±16.9 years. The most common symptom was abdominal pain (94, 52.8%). The mean cyst size was 9.5±3.9 cm. Eosinophilia was significantly higher in patients with complicated cyst (35.3%) (p=0.002). The average duration of hospitalization in surgical patients was shorter than non-surgical patients (p=0.026). There was no significant correlation between the preference of scolicidal agent (hypertonic saline, H2O2, povidone iodine) and recurrence in patients who underwent surgery (p>0.05). There was no significant difference between the patients who underwent radical and conservative surgery in terms of complication and recurrence (p=0.077, p=0.557). No significant difference was found between percutaneous and surgical treatment in terms of complication and recurrence (p=0.264, p=0.276).Conclusion: Even though considerable progress has been made, uncertainties remain in the diagnosis and treatment of Echinococcosis. Hence, standardized diagnostic and treatment procedures should be established with well-designed studies.Keywords: Echinococcosis, hydatid cyst, diagnosis, treatment

Model based analysis of insider threats
In order to detect malicious insider attacks it is important to model and analyse infrastructures and policies of organisations and the insiders acting within them. We extend formal approaches that allow modelling such scenarios by quantitative aspects to enable a precise analysis of security designs. Our framework enables evaluating the risks of an insider attack to happen quantitatively. The framework first identifies an insider's intention to perform an inside attack, using Bayesian networks, and in a second phase computes the probability of success for an inside attack by this actor, using probabilistic model checking. We provide prototype tool support using Matlab for Bayesian networks and PRISM for the analysis of Markov decision processes, and validate the framework with case studies
