Opis:
In recent years, Global Navigation Satellite Systems (GNSS) have gained great importance in terms of the benefi ts it provides such as precise geodetic point positioning, determining crustal deformations, navigation, vehicle monitoring systems and meteorological applications etc. As in Turkey, for this purpose, each country has set up its own GNSS station networks like Turkish National Permanent RTK Network analyzed precise station coordinates and velocities together with the International GNSS Service, Turkish National Fundamental GPS Network and Turkish National Permanent GNSS Network (TNPGN) stations not only are utilized as precise positioning but also GNSS meteorology studies so total number of stations are increased. This work is related to the reactivated of the TRAB IGS station which was established in Karadeniz Technical University, Department of Geomatics Engineering. Within the COST ES1206 Action (GNSS4SWEC) KTU analysis center was established and Trop-NET system developed by Geodetic Observatory Pecny (GOP, RIGTC) in order to troposphere monitoring. The project titled “Using Regional GNSS Networks to Strengthen Severe Weather Prediction” was accepted to the scientifi c and technological research council of Turkey (TUBITAK). With this project, we will design 2 new constructed GNSS reference station network. Using observation data of network, we will compare water vapor distribution derived by GNSS Meteorology and GNSS Tomography. At this time, KTU AC was accepted as E-GVAP Analysis Centre in December 2016. KTU reference station is aimed to be a member of the EUREF network with these studies.

Opis:
Graves’ orbitopathy is a rare autoimmune disorder characterized by the inflammation of orbital tissues. The course of disease can be described in terms of its activity and severity. Aim: The aim of our study was to determine the factors affecting the activity and severity of Graves’ orbitopathy, as well as to identify the predictive factors of poor response to glucocorticoid treatment followed by orbital irradiation. Methods: We performed a prospective observational study of 214 patients with Graves’ orbitopathy who were divided into two groups depending on the treatment they had previously obtained for their Graves’ disease. They received i.v. methylprednisolone pulses followed by orbital radiotherapy. They were examined and had their TSH, TRAb and FT4 levels evaluated prior to treatment and after 1, 6 and 12 months. Results: A pre-treatment TRAb concentration higher by one unit (U/L) implied a mean increase in the relative risk of active orbitopathy by 4.7% (p = 0.0362). A TRAb concentration higher by one U/L 1 month after treatment implied a mean increase in the relative risk of moderate-to-severe and severe GO by 8.7% (p = 0.0167) 6 months after treatment. As regards poor response to treatment, patients with moderate-to-severe and severe Graves’ orbitopathy on admission carried a higher risk of being non-responders. Each point scored on the NOSPECS scale prior to treatment increased the relative risk of the patient being a non-responder by 30%. Conclusions: Patients with higher TRAb levels have a higher risk of active Graves’ orbitopathy and moderate-to-severe and severe Graves’ orbitopathy. Monitoring TRAb serum concentration in those patients is of great importance. Patients with more severe Graves’ orbitopathy carry a higher risk of being poor responders to immunosuppressive treatment. Therefore, careful monitoring of patients with Graves’ orbitopathy and their early referral to specialized centers is essential.
