    Selection of the most suitable sizes of ground control points in the satellite images
    (International Society for Photogrammetry and Remote Sensing, 2004) Yilmaz H.M.; Yakar M.; Mutluoglu O.; Yildiz F.
    Nowadays, satellite images have been used for many applications intensively. Using of the digital satellite images in relevant approaches may give more accurate ideas about the researched fields. Besides, different methods could be used for derivation of maps from relevant digital data in many scientific disciplines. One of these methods is to use satellite images. The most important reason of using the maps, which are derived from satellite images, is accuracy of data. To obtain maps from satellite images or use satellite images as map, the satellite images required certain rectification. For a rectification process, ground control points are plotted in field. In the present study, the most suitable ground control point sizes were investigated for multi-spectral images from IKONOS satellite of one-meter resolution. The present study showed that the most suitable size of ground control point was 2.5 m diameter points. © 2004 International Society for Photogrammetry and Remote Sensing. All rights reserved.

    The effects of inhaled steroid and theophylline on systemic inflammation in COPD
    (2011) Boyacy H.; Pala A.; Argun Bariş S.; Basyigit I.; Yildiz F.; Ilgazli A.
    Chronic obstructive pulmonary disease (COPD) is a systemic disease characterized by chronic, progressive airflow limitation and airway inflammation. In this study, our aim is to compare the effects of inhaled corticosteroids and theophylline on systemic inflammatory markers in COPD. Twenty-nine moderate to severe COPD patients were randomly separated into two groups. In Group 1, inhaled corticosteroids (fluticasone propionate, 1000 mcg/ day) were added to regular bronchodilator therapy for 8 weeks, and theophylline (400mg/day) was added in Group 2. Pulmonary function tests were performed and serum CRP, TNF-?, and IL-6 levels were measured before and after treatment. There was a statistically significant decrease in serum CRP levels in both groups following treatment (ICS group 1.06±1.2 vs 0.49±0.22 mg/dl p< 0.05; THEO group 1.66±2.23 vs 0.59±0.35 mg/dl p< 0.05). There was a significant reduction in serum TNF-? levels in the THEO group (3.82±3.44 vs 1.89±1.33 pg/ml p< 0.05). There was no significant change in IL-6 level following treatment in either group. There was a significant increase in FEV 1 in the ICS group while a non-significant increase was noted in the THEO group following treatment. It has been suggested that both ICS and THEO could be used as an anti-inflammatory agent in the treatment of COPD. Furthermore, the measurement of serum inflammatory markers is an easy and non-invasive method for the determination and follow-up of systemic inflammation in COPD. Further studies including larger patient population are needed. Copyright © by BIOLIFE, s.a.s.
