The only existing heavy-ion accelerator in Greece, the 5.5 MV TANDEM at the National Research Center “Demokritos” in Athens has been used to date primarily for investigations centering around nuclear physics. Here, we propose to establish the new (for Greece) discipline of Atomic Physics with Accelerators, a strong field in the EU with important contributions to fusion, hot plasmas, astrophysics, accelerator technology and basic atomic physics of ion-atom collision dynamics, structure and technology. This will be accomplished by combining the existing interdisciplinary atomic collisions expertise from three Greek universities, the strong support of distinguished foreign researchers and the high technical ion-beam know-how of the TANDEM group into a cohesive initiative.Using the technique of Zero-degree Auger Projectile Spectroscopy (ZAPS), we shall complete a much needed systematic isoelectronic investigation of K-Auger spectra emitted from collisions of pre-excited ions with gas targets using novel techniques. Our results are expected to lead to a deeper understanding of the neglected importance of cascade feeding of metastable states [1] in collisions of ions with gas targets and further elucidate their role in the non-statistical production of excited three-electron states by electron capture, recently a field of conflicting interpretations awaiting further resolution.
Towards the development of a radiological box model for Aegean Sea: considerations and perspectives
Authors: Eleftheriou G. , Iøsjpe M.
Published: February 2020

The development steps of the radiological box model of the Aegean Sea are presented here. The applied methodology combines all the available and necessary site specific information. The modelling approach includes terms describing the radionuclide dispersion into oceanic space with time (non-instantaneous mixing), while the model’s algorithms also cover whole processes of radionuclides’ transfer, bioaccumulation and doses assessment. The model includes 50 marine and sediment boxes, optimized based on experimental radiocesium measurements followed the Chernobyl accident. The process is expected to reveal the key parameters controlling the radionuclides’ fate as well as their effect on the model’s prediction.

Some More Insight into the Fate of the "Skevra Evangeliary"

The colophons of the Armenian manuscripts from Crimea that were recently published by Tatevik E. Sargsyan make it possible to put forward a thesis that the 12th-century evangeliary created in Skevra (Cilician Armenia), which is now held in the National Library in Warsaw, was kept in Crimea during the 15th century. At the time it belonged to Simeon, a monk from the hermitage of St. Gregory the Illuminator, next to Saint John the Baptist Church in Otuz, and was later sold in 1422 to its next owner known under the name of Khutlupek. There are no other records of this book prior to those found in Lwów (Lviv) in 1592. Its history before that year remains unknown.
Evolution of Legg-Calvé-Perthes disease following proximal femoral varus osteotomy performed in the avascular necrosis stage: A prospective study
Authors: Singh Kumar Amerendra , Shah Hitesh , Joseph Benjamin , Aarvold Alexander , Kim Harry K. W.
Published: February 2020

Purpose

This prospective study was undertaken to describe patterns of fragmentation of the femoral epiphysis following a proximal femoral varus osteotomy (PFVO) done during stage I of LCPD and to assess the disease duration and outcome in each pattern.

Methods

A total of 25 children treated by a PFVO in stage I of LCPD were followed until healing. The MRI Perfusion Index, radiographic changes in the femoral epiphysis, disease duration and the Sphericity Deviation Score (SDS) at healing were documented. The reproducibility of classification of the pattern of fragmentation, estimation of disease duration and SDS were assessed. The duration of the disease and SDS in the patterns of fragmentation were compared.

Results

Four patterns of fragmentation were noted, namely, typical fragmentation, bypassing fragmentation, abortive fragmentation and atypical fragmentation with horizontal fissuring. The reproducibility of classifying the pattern of fragmentation was moderate (Kappa: 0.48) while the reproducibility of other continuous variables was excellent. The Perfusion Index was less than 50% in every affected hip. The duration of the disease and SDS were lowest in children in whom the stage of fragmentation was bypassed but these differences were not statistically significant.

Conclusion

Following a proximal femoral osteotomy during stage I of LCPD the fragmentation stage may be bypassed partially or completely and the chances of a good outcome appear to be very good if fragmentation is bypassed.

Is early migration enough to explain late clinical loosening of hip prostheses?
Authors: Mjöberg Bengt
Published: February 2020

Prosthetic loosening has been debated for decades, both in terms of the timing and nature of the triggering events. Multiple radiostereometric studies of hip prostheses have now shown that early migration poses a risk of future clinical failure, but is this enough to explain late clinical loosening? To answer this question, the progression of loosening from initiation to radiographic detection is described; and the need for explanations other than early prosthetic loosening is analysed, such as stress-shielding, particle disease, and metal sensitivity. Much evidence indicates that prosthetic loosening has already been initiated during or shortly after the surgery, and that the subsequent progression of loosening is affected by biomechanical factors, fluid pressure fluctuations and inflammatory responses to necrotic cells and cell fragments, i.e. the concept of late loosening appears to be a misinterpretation of late-detected loosening. Clinical implications: atraumatic surgery and initial prosthetic stability are crucial in ensuring low risk of prosthetic loosening.

Chondrosarcomas in children and adolescents
Authors: Puri Ajay
Published: February 2020

Chondrosarcomas in children and adolescents are uncommon and constitute < 5% of all chondrosarcomas. There are very few studies discussing extremity chondrosarcomas in young patients. The pelvis is the most common site, followed by the proximal femur. As cartilaginous tumours can be quite challenging to diagnose, it is best for these lesions to be discussed in a multidisciplinary meeting which includes a radiologist and a pathologist specializing in bone tumours. Treatment principles are similar to those in adults, with adequate surgical excision respecting oncologic principles being the mainstay of treatment. Select extremity Grade I chondrosarcomas may be managed with extended intralesional curettage without increasing the risk for local recurrence or metastatic disease, but case selection is critical and should be based on clinical, imaging and histological characteristics. Chondrosarcomas are resistant to chemotherapy and relatively radioresistant. For mesenchymal chondrosarcomas, there may be a role for chemotherapy, though data on this is limited. Prognosis and rate of recurrence correlate directly to the adequacy of the surgical resection. Chondrosarcomas in younger patients behave in a similar fashion to those in adults, and outcomes in the young are no different from those in adults.

CONTROL SYSTEM FOR COMPLETE BURNING IN FURNACE USING LAMBDA PROBE
Authors: Pedruzi Gerson Ovidio Luz , Rodrigues Santos Raquel , De Oliveira Resende Michael , Arêdes Martins Márcio , Meira Santana Marcus
Published: February 2020

The objective of this work was to evaluate the biomass burning process in a furnace, using chip as a raw material and an oxygen sensor (lambda probe) to monitor the percentage of oxygen in the gases exhausted during combustion, aiming to maintain the percentage of the coefficient of excess air (α) in the operating range of 1.20 to 1.25%, considered ideal for the biomass (chip) used in the study. Once the excess air is identified at the upper furnace exit, the air entrance in the system will be closed by means of a butterfly valve using a servo motor driven by a Programmable Logic Controller (PLC). The valve was opened or closed according to the oxygen level; when it was lower than 1.20%, the door remained open, and it was closed when the level reached 1.25%, finishing the cycle of the process. The open and closed states of the valve occurred by means of two reed switch magnetic key sensors installed in the air intake system. For the control, monitoring and data acquisition, a supervisory system created using the Elipse SCADA software was used so it was possible to obtain a system database, which will provide important information to maximize the efficiency of the furnace.

Software Defect Prediction (SDP) provides insights that can help software teams to allocate their limited resources in developing software systems. It predicts likely defective modules and helps avoid pitfalls that are associated with such modules. However, these insights may be inaccurate and unreliable if parameters of SDP models are not taken into consideration. In this study, the effect of parameter tuning on the k nearest neighbor (k-NN) in SDP was investigated. More specifically, the impact of varying and selecting optimal k value, the influence of distance weighting and the impact of distance functions on k-NN. An experiment was designed to investigate this problem in SDP over 6 software defect datasets. The experimental results revealed that k value should be greater than 1 (default) as the average RMSE values of k-NN when k>1(0.2727) is less than when k=1(default) (0.3296). In addition, the predictive performance of k-NN with distance weighing improved by 8.82% and 1.7% based on AUC and accuracy respectively. In terms of the distance function, kNN models based on Dilca distance function performed better than the Euclidean distance function (default distance function). Hence, we conclude that parameter tuning has a positive effect on the predictive performance of k-NN in SDP.
User position tracking system using marker-based AR for exploring VR museum galleries
Authors: Anggoro Pius Dian Widi
Published: February 2020

This study examines the user position tracking system using marker-based AR on smartphones camera. The tracking system uses a homographic algorithm integrated into the Galeri Museum VR application. In the test, the user performed exploration interactions by 6 degrees of freedom in ten different positions in the museum gallery. The physical space used in this study was 4 x 4 m2 and a marker attached to the wall in front of the user. This system results in errors in XYZ field (0.102 m, 0.047 m, 0.044 m). If the camera's orientation is not directing to the marker and the user is moving, jitter appears because of the untracked marker. The use of marker-based AR successfully applied to track the position of users who perform natural locomotion interactions in the VR environment.

Published: February 2020

The encryption of digital images has become essential since it is vulnerable to interception while being transmitted or stored. A new image encryption algorithm to address the security challenges of traditional image encryption algorithms is presented in this research. The proposed scheme transforms the pixel information of an original image by taking into consideration the pixel location such that two neighboring pixels are processed via two separate algorithms. The proposed scheme utilized the Gray code number system. The experimental results and comparison shows the encrypted images were different from the original images. Also, pixel histogram revealed that the distribution of the plain images and their decrypted images have the same pixel histogram distributions, which means that there is a high correlation between the original images and decrypted images. The scheme also offers strong resistance to statistical attacks.

Published: February 2020

The paper focuses on the competence of the European Parliament and the EU Council to adopt directives in the area of substantive criminal law provided in Articles 83 and 84 of the TFEU, which confirm the earlier ECJ rulings on the subject. The competence granted to those institutions also ensure greater effectives of the adopted directives in combating serious crimes within the European Union. The creation of certain ‘emergency brakes’ and application of the principle of proportionality taking into account the fundamental principles of criminal law systems of individual Member States, has enabled the EU institutions to establish common definitions of most serious crimes.

The essay presents the issue of the principle of self-determination from the perspective of international human rights law. The author highlights the close relationship between the principle of self-determination and the principle of respect for human rights and fundamental freedoms. In practice, the principle of self-determination is a prerequisite for the effective guarantee of human rights, and, at the same time, guaranteed protection of human rights is a prerequisite for implementing the principle of national self determination. The author presents the issue of self-determination in the context of the basic regulations of international human rights law, considering regulations of both a ‘hard’ and ‘soft’ law character.
Linguistic Human Rights in Education
Authors: Szoszkiewicz Łukasz
Published: February 2020

Linguistic human rights are a concept remaining on the crossroads of several scientific disciplines, e.g. linguistics, anthropology, psychology and, last but not least, human rights law. Taking the latter as a lens, this study seeks to clarify the concept of linguistic human rights in education – presumably, the most linguistically sensitive sphere in the life of individuals and communities. The paper demonstrates that despite little mention of language in the UN treaties (ICESCR, CRC, CERD, CADE), its importance is reflected in the practice of the relevant treaty-based bodies. Moreover, increasing interest from scholars across a range of disciplines is contributing to the development of a linguistic human rights doctrine and is penetrating the UN human rights framework.

İşletmeler, gittikçe artan ölçüde, kendi sahip oldukları yetenek ve becerilere dayalı işleri yapmak istemekte ve öz (temel-çekirdek) yetkinliklerini kullanmadıkları işlerin yapılmasında dış kaynaklardan yararlanmayı tercih etmektedirler. Son yıllarda insan kaynakları yönetimi faaliyetlerinde dış kaynaklardan yararlanma yoluna gidildiği görülmektedir. İşletmelerin dış kaynaklardan yararlanmaya yönelmelerinde iki temel yaklaşımın etkisi söz konusu olmaktadır. Bunlardan birincisi olan “Maliyetlere Dayalı Yaklaşım”; işletmeye özgü olmayan faaliyetler (örneğin; taşıma, temizlik, güvenlik vb...) için dış kaynaklardan yararlanılması gerektiğini ileri sürerken; “Kaynaklara Dayalı Yaklaşım” ise işletmenin temel faaliyetleri açısından kritik olmayan konularda dış kaynaklardan destek alınmasını ileri sürmektedir. Çalışmamızda ele aldığımız işletmelerde, insan kaynakları yönetimi işlevinin (insan kaynakları bölümlerinin) hangi yaklaşımlar /gerekçeler doğrultusunda dış kaynaklardan yararlanma uygulamalarına geçtikleri belirlenmeye çalışılmıştır.

Published: February 2020

Neutrophil is a key element in inflammation and stress disease, which are associated with poor clinical outcomes in various cardiac diseases. However, the clinical availability of neutrophil in patients with ST-elevation myocardial infarction (STEMI) and chronic renal dysfunction has not been known. Accordingly, we designed this retrospective cohort study to evaluate the differences of major adverse cardiovascular events incidence between renal dysfunctional STEMI patients with normal and high neutrophil levels. The primary end point was all-cause mortality. We analyzed 377 consecutive STEMI patients with chronic renal dysfunction. The results showed that during 12-48 months follow-up, death from any-cause occurred in 1.4% patients (4 of 290) in normal-level neutrophil group, as compared with 3.4% in high-level neutrophil group (3 of 87) (hazard ratio, 2.174 95% confidence interval, 1.024-10.248; P = 0.025). Kaplan-Meier survival analysis showed that there were significant differences between the two groups with respect to the risk of death (P=0.018), and heart failure (P=0.037).

Published: February 2020

The effect of V-pits in the upper waveguide (UWG) on device performance of GaN-based laser diodes (LDs) has been studied. Experimental results demonstrate that in comparison with the LDs with u-In0.017Ga0.983N/u-GaN multiple UWG or u-In0.017Ga0.983N one, the LDs with a single u-GaN UWG has the best device performance. They have a smaller threshold current density, and a larger and more stable output optical power. The lowest threshold current density is as low as 1.3 kA/cm2, and the optical power reaches to 2.77 W. Furthermore, atomic force microscopy suggests that the deterioration of device performance of former kinds of devices may be attributed to the increase of V-pits’ size and quantity in the undoped-In0.017Ga0.983N UWG layer, and these V-pits could introduce more nonradiative recombination centers and exacerbate the inhomogeneity of injection current. Moreover, theoretical calculation results indicate that the increase of leakage current and optical loss are additional reasons for the device performance deterioration, which may be caused by a reduction of the potential barrier height for electrons in the quantum wells and by an increased background electron concentration in UWG.
Proportional Downscaling of Glutamatergic Release Sites by the General Anesthetic Propofol atDrosophilaMotor Nerve Terminals

Published: February 2020

Propofol is the most common general anesthetic used for surgery in humans, yet its complete mechanism of action remains elusive. In addition to potentiating inhibitory synapses in the brain, propofol also impairs excitatory neurotransmission. We use electrophysiological recordings from individual glutamatergic boutons in male and female larvalDrosophila melanogastermotor nerve terminals to characterize this effect. We recorded from two bouton types, which have distinct presynaptic physiology and different average numbers of release sites or active zones. We show that a clinically relevant dose of propofol (3 μm) impairs neurotransmitter release similarly at both bouton types by decreasing the number of active release sites by half, without affecting release probability. In contrast, an analog of propofol has no effect on glutamate release. Coexpressing a truncated syntaxin1A protein in presynaptic boutons completely blocked this effect of propofol. Overexpressing wild-type syntaxin1A in boutons also conferred a level of resistance by increasing the number of active release sites to a physiological ceiling set by the number of active zones or T-bars, and in this way counteracting the effect of propofol. These results point to the presynaptic release machinery as a target for the general anesthetic. Proportionally equivalent effects of propofol on the number of active release sites across the different bouton types suggests that glutamatergic circuits that involve smaller boutons with fewer release sites may be more vulnerable to the presynaptic effects of the drug.
“Teaching the Abbasid Muḥdathūn at the Global Turn”1
Authors: Fakhreddine Huda J.
Published: February 2020

This essay addresses the challenges of teaching the poetry of the Abbasid modernizers (muḥdathūn) in a global context. The historicist approach to Arabic poetry in general, and to pre-modern Arabic poetry in particular, makes it difficult to engage with the work of these revolutionary poets poetically. A creative and comparatist approach to translation and an insistence on foregrounding this poetry’s relevance beyond its historical moment are ways of overcoming the hegemony of the historical imperative and inviting students to connect with this body of literature rhetorically and creatively. My observations are grounded in readings of samples from the work of Abbasid poets Abū Nuwās (d. 815) and Abū Tammām (d.845).

AbstractParkinson’s disease is a neurological disorder in which there is a gradual loss of brain cells that make and store dopamine. Researchers estimate that four to six million people worldwide, are living with Parkinson’s. The average age of patients is 60 years old, but some are diagnosed at age 40 or even younger and the worst thing is some patients are late to find out that they have Parkinson's disease. In this paper, we present a diagnosis system based on Fuzzy K-Nearest Neighbor (FKNN) to detect Parkinson’s disease. We use Parkinson’s disease dataset taken from UCI Machine Learning Repository. The first step is normalize the Parkinson’s disease dataset and analyze using Principal Component Analysis (PCA). The result shows that there are four new factors that influence Parkinson’s disease with total variance is 85.719%. In classification step, we use several percentage of training data to classify (detect) the Parkinson's disease i.e. 50%, 60%, 70%, 75%, 80% and 90%. We also use k = 3, 5, 7, and 9. The classification result shows that the highest accuracy obtained for the percentage of training data is 90% and k = 5, where 19 are correctly classified i.e. 14 positive data and 5 negative data, while 1 positive data is classified incorrectly.Keywords: Parkinson's disease; Fuzzy K-Nearest Neighbor; Principal Component Analysis. AbstrakPenyakit Parkinson merupakan kelainan sel saraf pada otak yang menyebabkan hilangnya dopamin pada otak. Para peneliti mengestimasi bahwa, empat sampai enam juta orang di dunia, menderita Parkinson. Penyakit ini rata-rata diderita oleh pasien berusia 60 tahun, namun beberapa orang terdeteksi saat berusia 40 tahun atau lebih muda dan hal terburuk adalah seseorang terlambat untuk mendeteksinya. Di dalam artikel ini, kami menyajikan sistem diagnosa penyakit Parkinson menggunakan metode Fuzzy K-Nearest Neighbor (FKNN). Kami menggunakan Data uji yang diperoleh dari UCI Machine Learning Repository yang telah banyak diterapkan pada masalah klasifikasi. Tahapan pertama yang kami lakukan adalah menormalisasi data kemudian menganalisisnya menggunakan Analisis Komponen Utama (Principal Component Analysis). Hasil Analisis Komponen Utama menunjukkan bahwa terdapat empat factor baru yang mempengaruhi penyakit Parkinson dengan variansi total 87,719%. Pada tahap klasifikasi, kami menggunakan beberapa prosentase data latih untuk mendeteksi penyakit yaitu 50%, 60%, 70%, 75%, 80% and 90%. Selain itu, kami menggunakan beberapa nilai k yaitu 3, 5, 7, and 9. Hasil menunjukkan bahwa klasifikasi dengan akurasi tertinggi diperoleh untuk 90% data latih dengan k = 5, dimana 19 diklasifikasikan secara tepat yaitu 14 data positif dan 5 data negatif, sedangkan satu data positif tidak diklasifikasikan dengan tepat.Keywords: penyakit Parkinson; Fuzzy K-Nearest Neighbor; Analisis Komponen Utama.
La representación social sobre lo indígena urbano en Costa Rica. El caso de mujeres ngäbes-buglé panameñas
Authors: Pérez Granados Mónica María
Published: February 2020

Exploro la representación social (RS) sobre “lo indígena urbano”, en concreto, el caso de mujeres ngäbe-buglé de origen panameño ubicadas en la Avenida Central, en San José de Costa Rica, y las consecuencias de la misma en el ejercicio de derechos. Para cumplir con tal propósito, utilizo el concepto de RS de la Escuela Francesa de Psicología Social, que las considera como constructos establecidos en la intersubjetividad, sobre un objeto social, que orientan la acción. Considerando que estas se expresan en los discursos de los actores sociales, realicé visitas periódicas en esa avenida, durante los meses de octubre y noviembre de 2018, en ese lapso conversé con transeúntes, y entrevisté a trabajadores(as) del área. Como resultado, encontré que la RS sobre “lo indígena urbano” se contrapone a la de “lo indígena” nacida en el marco del colonialismo, lo cual deviene en discriminación, a la vez que limita la aplicación de la normativa internacional que reconoce los derechos de personas y pueblos indígenas.
Balance control of the orthostatic body pose in physical education of students
Authors: Zanevskyy Ihor , Nowak Stanislaw
Published: February 2020

Background and Study Aim. Maintaining upright body posture is fundamental for humans. The aim of the research is to determine influence of the feet situation on the balance of the orthostatic body pose in physical education.
Material and Methods. Ten 19–21 years old university students were involved into the research. The test consisted of five measurements − each of them in another feet situation with ten minutes relax before every measurement. Measurements were done using two twin platforms kinesis-meter CQStab2P. A length of the horizontal projection of centre of pressure during 30 seconds was measured as a test result.
Results. Because near normal distribution (SW-W = 0.893−0.963, p = 0.183−0.806), parametric statistics were used to elaborate results on the balance test reliability: two ways ANOVA, intra-class correlation, t-Student, and Pearson correlation. Groups variations of results in all the five feet situations were derived about the border between moderate and great: V = 20.0 − 23.5%. Test-retest results correlate between groups repeated measurement on moderate − high levels (r = 0.593 − 0.954).
Conclusions. In the balance control of the orthostatic body pose in the physical education of students a feet situation should be taken into consideration, because a significant difference between lengths of the centre of pressure during the control on the balance platform relatively a body pose (p < .046). Balance testing on the platform could be conducted on the appropriable, good, and excellent levels of reliability using intra-class correlation coefficient (ICC = 0.791 – 0.975).

This study compares the physico- and electro- chemical properties of LiNi0.8Mn0.10Co0.1O2 (NMC811) and LiNi0.83Mn0.06Co0.09Al0.1O2 (NMCA) prepared by an oxalic acid co-precipitation. Deposition of a SiO2 surface coating was attempted via reaction of the powder with an amino silane prior to the final heat treatment. It was found that either the presence of small amounts of Al3+, or the compositional gradient resulting from a two step co-precipitation, caused increased crystal growth of the NMCA in comparison to NMC811. This led to improved cyclability in LP40 electrolyte. However, the SiO2 coating appeared incomplete and negatively impacted performance. Crystal cleavage preferably on the 001 planes was observed after 100 charge-discharge cycles, with consequent cathode electrolyte interphase formation in the crystal cracks. This is believed to cause capacity decay via lithium loss, and increased charge transfer resistance. An FEC based electrolyte improved the cyclability in all cases and even under extreme conditions (45°C and upper cycling potential of 4.5 V) NMCA showed a capacity retention of 85% after 100 cycles.

A contribuição do pensamento de Paul Tillich para a importância da religião nas culturas urbanas da atualidade
Authors: Cunha Carlos Alberto Motta
Published: February 2020

O pensamento de Paul Tillich continua atual e desafiador. Em 2019, completa 100 anos da conferência proferida por ele na sociedade kantiana de Berlim, 16 de abril de 1919, intitulada “Sobre a ideia de uma teologia da cultura”. A explanação de Tillich é tida como o marco inicial da sua Teologia da Cultura e fonte de inspiração para pensar a correlação entre religião e cultura. Em comemoração a esse referencial, a reflexão aqui proposta busca fazer alguns apontamentos introdutórios sobre a contribuição do pensamento tillichiano para a importância da religião nas culturas urbanas da atualidade. Para isto, o texto está dividido em dois momentos. Primeiro, uma breve análise da crise da religião, do sujeito religioso e da devoção ao mercado financeiro, segundo, a teologia da cultura de Tillich empenhada em ressignificar os símbolos da fé e correlacionar religião e cultura como caminho de busca de sentido para o ser humano de hoje.
Signage Form and Character
Authors: Nafisur Rahman Muhammad , Mehta Vikas
Published: February 2020

Signs contribute significantly to the visual identity of neighborhoods, often representing the interplay of the collective social, political, cultural and economic values of the people who live and work there. On-premise signs displayed on building facades and storefronts in the neighborhood business district of three distinct neighborhoods in Cincinnati, OH are examined to document the typographic styles and form (material, size and scale, color, etc.) of the signs. An empirical photographic survey is employed for elevation mapping, to record the full range of on-premise signs in each neighborhood business district. Over 150 on-premise signs are documented and analyzed. Our findings suggest that as neighborhoods get gentrified, particularly with non-local capital and investment, the signage form and character, represented by the typeface, shape, material, illumination and other properties, become more homogeneous, replacing the variety of typefaces as well as signage form. The study found that the signage used by the chain stores and other new businesses that are not place based to be mostly all-capitalized, three-dimensional, back-lit, and having other properties that are undifferentiated, generic, and visually monotonous.

Published: February 2020

ÖZ Amaç:
Lökositoklastik vaskülit, primer deri tutulumu ile seyreden, esas olarak
post kapiller venülleri
etkileyen bir küçük damar vaskülit formudur. Etiyolojide ilaçlar, enfeksiyonlar, maligniteler,
sistemik inflamatuvar hastalıklar gibi çeşitli nedenler yer almaktadır. Ancak
olguların bir kısmında neden
saptanamamakta ve bu olgular idiyopatik olarak değerlendirilmektedir. Klinik olarak özellikle alt ekstremitelerde sınırlı
palpe edilebilen purpuralar ile karakterize olup,
nadiren yaygın tutulum da gözlenebilmektedir. Bu çalışmada, kliniğimizde lökositoklastik
vaskülit tanısı almış hastalarda etiyolojik faktörler, demografik ve klinik özelliklerin belirlenmesi amaçlanmıştır. Gereç
ve Yöntemler: Çalışmaya Ocak 2018 - Nisan 
2019 arasında Romatoloji Bilim Dalında 2012 Uluslararası Chapel Hill
Toplantısına göre lökositoklastik vaskülit  tanısı konulan 
40 hasta dahil edildi. Çalışmaya 18 yaş üstü hastalar dahil edildi.
Hastaların epidemiyolojik, klinik,
laboratuar bulguları ve tedavi bilgileri retrospektif olarak dosya kayıtları
incelenerek elde edildi.Bulgular: Kırk hastanın (25 kadın, 15 erkek)
yaş ortalaması 48.02±19.9 olduğu tespit edildi. Kutanöz lezyonlar en sık alt
ekstremite yerleşimli, palpe edilebilen purpurik
papül-plaklar şeklindeydi ve lezyonlara en sık eşlik eden semptomun kaşıntı olduğu saptandı.
Hastaların %37.5 ’inde herhangi
bir etyolojik neden saptanmamasına karşın,
kalan hastaların %25’inde
enfeksiyon ve/veya ilaç kullanımı öyküsü
mevcuttu. Hastaların % 37.5’ine malignite
ve romatizmal hastalık eşlik ediyordu.
Sistemik kortikosteroidler en sık tercih
edilen tedavi seçeneğiydi.

Sonuç: Lökositoklastik vaskülit çoğunlukla ilaçlar ve enfeksiyon tarafından tetiklenen, malignite ve romatolojik
hastalıkların da eşlik edebileceği iyi seyirli, kendi kendini sınırlayan bir hastalıktır. Altta yatan etiyolojinin belirlenmesi tedavide önemli bir basamak
olmakla birlikte sistemik kortikosteroidler de etkin
bir tedavi seçeneğidir.

Akhaimenid Döneminde Büyük Phrygia ve Bölgedeki Yol Ağları
Authors: DURAN Muzaffer
Published: February 2020

Persler Anadolu’ya hakim olduktan sonra Anadolu topraklarını idari yönetim bölgelerine (satraplık) ayırmıştı. Bu bölgelerden biri de Phrygia’dır. Ancak Pers döneminde Hellespontos Phrygia’sı (Daskyleion) ve Büyük Phrygia adı altında iki ayrı Phrygia bulunmaktaydı. Kıyı Phrygia olarak da bilinen Hellespontos Phrygia’sı üzerine yapılan bir çok çalışma mevcuttur. Ancak doğrudan Büyük Phrygia adı altında yapılan çalışmalar oldukça sınırlıdır. Bu çalışmamızın temel amacı Pers döneminde Büyük Phrygia’da vuku bulan meseleler; bölgede söz sahibi olan yöneticiler; bölgede bulunan şehirler ve yol ağlarına dair açıklamalarda bulunmaktır. Bu hususta bir çok sorun bulunmaktadır. Sorunların kaynağı antik kaynakların yeterince bilgi vermemesidir. Çalışmamızın neticesinde Büyük Phrygia hakkında MÖ. 4. yüzyıldan itibaren kaynakların daha fazla bilgi vermeye başladığını; bölgenin özellikle II. Artakserkses dönemi ile birlikte sorunlara gebe kaldığını; aynı yüzyıldan itibaren bölgede çıkan ayaklanmalar ve dış müdahaleler konusunda Anadolu’nun batısındaki diğer satraplıklara nazaran olayların çok fazla içinde yer almadığını; Kral Yolu güzergahında bulunmasından dolayı bölgenin stratejik öneme haiz olduğunu; özellikle Kelainai kentinin anahtar şehir konumunda bulunduğunu söyleyebiliriz.
