The analysis of convergence process of voivodships’ efficiency in Poland using the DEA metod

Since 1999 – when the new administrative division in Poland was introduced – it has been possible to measure and compare standard of living between Polish and other European regions (NUTS II). In 2004 Poland has joined the European Union. Since that year voivodships have become main beneficiaries of the EU funds. The essential part of that aid is related to the EU cohesion policy (convergence objective). According to the fifth cohesion report “cohesion policy has made a significant contribution to spreading growth and prosperity across the Union, while reducing economic, social and territorial disparitiesâ€. However, the differences in standard of living still remains significant between countries as well as between regions within one country. In many researches the level of welfare is measured using “classic†indicators (GDP per capita, GNI per capita, unemployment rate, etc.). In this paper the authors focus on the regional economies’ efficiency. The efficiency will be measured using the Data Envelopment Analysis. Due to the method used, the efficiency will be measured as relative in nature, i.e. will be compared between voivodships within the period of research. The goal of the paper is to analyze variety of relative voivodships’ efficiency in order to answer the question if the dispersion in efficiency is increasing or decreasing over time.

Advances in Molecular Characterization and Targeted Therapy in Dermatofibrosarcoma Protuberans

The molecular pathogenesis of dermatofibrosarcoma protuberans (DFSP) involves distinctive rearrangement of chromosomes 17 and 22 leading to formation of the COL1A1-PDGFB fusion gene. The knowledge of molecular events underlying development of DFSP resulted in the implementation of targeted therapy with imatinib—a tyrosine kinase inhibitor (TKI), to the clinical practice. The striking efficacy of imatinib in advanced cases of DFSP has been demonstrated in a few clinical trials. Thus, imatinib is currently considered the gold standard in the treatment of inoperable and/or metastatic and/or recurrent cases of DFSP. Therapy with imatinib may potentially facilitate resection or decrease possible disfigurement related to radical surgical procedure. Following partial response on imatinib significant percentage of patients may be rendered free of the disease by surgery of the residual tumor

Placenta percreta leading to uterine rupture at 18 weeks of pregnancy with consecutive hysterectomy: a case report

A 26-year-old woman in the fourth pregnancy with a history of two Cesarean sections and one dilation and curettage was admitted to the hospital at 18 weeks of gestation with acute abdominal pain. Life-saving laparotomy revealed uterine rupture and placental invasion into the uterine wall. Supracervical hysterectomy was performed. This case shows that pathological placentation due to previous cesarean sections may be the cause of uterine rupture

EXTERNAL BARREL TEMPERATURE OF A SMALL BORE OLYMPIC RIFLE

Investigations on changes in a rifle’s barrel temperature during shooting in a rhythm typical for practitioners of Olympic shooting sports are presented. Walther KK300 (cal. 5.6 mm), a typical rifle often used in Olympic competitions, R50 RWS ammunition and a high speed thermographic camera were used in the study. Altair version 5 software was used to process thermal images and a stationary wavelet transform was applied to denoise signals for all the studied points. It was found that the temperature of the rifle barrel does not exceed 0.3°C after one shot whereas the total temperature increase does not exceed 5°C after taking 40 shots and does not affect the position of the hitting point on a target. In fact, contrary to popular belief, the so-called “warming shots” are not done for barrel heating but for cleaning of remnants in the barrel

Ultrasonographic signs of acute ovarian torsion

Ovarian torsion is defined as partial or complete rotation of the ovarian vascular pedicle and causes obstruction to venous outflow and arterial inflow. Teenage patient was referred to the gynecology ward with pain located in the lower, right abdomen, after an initial misdiagnosis of a dermoid cyst. The patient was diagnosed with a torsion of the right ovarian peduncle. The patient was given diastolic drugs and was discharged in good general condition two days later after the symptoms had resolved. Final USG showed normally vasculated corpus luteum. Among the various treatment options, the wait-and-watch attitude turned out to be the best solution. It is particularly important in the case of young patients, who are planning pregnancy in the future
