    Opis:
    Turning requirements into working systems is the essence of software engineering. This paper proposes automation of one of the aspects of this vast problem: generating user interfaces directly from requirements models. It presents syntax and semantics of a comprehensible yet precise domain specification language. For this language, the paper presents the process of generating code for the user interface elements. This includes model transformation procedures to generate window initiation code and event handlers associated with these windows. The process is illustrated with an example based on an actual system developed using the presented approach.

    Introduction and objective. In the light of current data concerning the growing exposure to ionizing radiation (IR) originating from atrificial sources, especially from medical ones, and also related to occupational exposure, it is justifiable to systematize the state of knowledge concerning the effect of IR on the male reproductive system. Brief description of the state of knowledge. There is no basis for the application of the hypothesis of hormesis in the area of male reproductive health. Regarding the impact of IR on spermatogenesis, spermatogonia are less susceptible to the occurrence of DNA damage after exposition to IR, but are characterized by slower DNA repair compared to somatic cells. Damage to the genes after exposure to IR is possible at each stage of spermatogenesis; however, haploidal spermatids show the highest radiosensitivity in this respect. The genetic risk of the cells differentiating during spermatogenesis is limited to one cycle of spermatogenesis, whereas the genetic instability may persist for the whole period of life, and DNA damage induced by IR may be transmitted to future generations. The minimum dose causing detectable DNA damage was 30 Gy. While exceeding this dose, the number of single-strand DNA breaks increases. Among males exposed to IR, a decrease was observed in sperm motility and in the percentage of morphologically normal spermatozoa as well as in an intensification of vacuolization. The genetic material in the sperm of these males showed higher fragmentation and methylation of genomic DNA. Conclusion. In the context of the epidemiological situation concerning the prevalence of infertility, while assessing the health effects of exposure to IR from artificial, including medical sources, the reproductive risk should be considered.

    Introduction and objective. Bioimpedance analysis (BIA) phase angle (PhA) is an index of the integrity of cells and cellular membranes. The aim of the study was identification of behavioural and anthropometric predictors of PhA in a group of young adults. Materials and method. A cross-sectional observational study of health behaviours, anthropometric indicators and body composition assessed by the BIA method was conducted in a group of Polish young adults (n=92) aged 18 – 24 (mean – 19.33, STD – 0.915). Behavioural variables included: level of physical activity, eating behaviours and nutritional knowledge. Body composition was analysed by means of BIA phase-sensitive 8-electrode medical SECA mBCA 525 device. Results. The mean PhA value in the examined cohort was 6.38±0.75 (males – 7.22±0.72; females – 6.13±0.57). Males also showed higher statistically significant other body composition indices, excluding fat mass. The multiple regression model, including anthropometric variables and gender, which explained the effect of these variables on PhA, occurred to be significant (p<0.0000) and allowed explanation of the 82.49% of PhA variability. PhA was significantly predicted from body mass index (BMI), absolute fat mass, visceral adipose tissue value, skeletal muscle mass value and gender. The regression model, including behavioural predictors and gender, allowed explanation of the lower percentage of PhA variability (42.75%; p<0.0000) and included general intensity of health behaviours, level of nutritional knowledge, and gender. A regression model which would consider simultaneously anthropometric and behavioural variables could not be constructed. Conclusions. In the examined cohort, anthropometric and body composition variables showed a stronger predictive value with respect to PhA, compared to behavioural variables.

    Opis:
    Purpose: of this article is to present the results of tests carried out on the impact of repeated heating on the corrosion resistance of a Co-Cr-W prosthetic alloy. Design/methodology/approach: The study used samples prepared in a manner analogous to the production of a dental prosthesis. The effect of three and six-time heating of the material on its properties such as corrosion resistance, microstructure and material hardness were carried out. Findings: Repeated heating of the chromium-cobalt alloy has no significant effect on the polarization resistance and the potentiodynamic characteristics of the material. The introduction of heating in alloy treatment results in an increase in the hardness of the material, however, the number of annealing cycles does not affect this feature significantly. Samples subjected to different amounts of thermal treatments have different microstructure; it should be assumed that this will change the mechanical properties. Research limitations/implications: Microstructure tests carried out after electrochemical corrosion tests showed changes in the microstructure of samples subjected to subsequent annealing. The tests of material hardness and corrosion did not show any significant differences that may result from differences in structure, therefore further tests characterizing the physical properties of the material will be carried out. Originality/value: The article is a description of preliminary research on the impact of multiple annealing used in dental prosthetics on the properties of metallic material. Further work will be carried out to identify the properties that may be affected by the indicated changes in microstructure.

    Introduction and objective. The tendency towards postponement of maternity implies a greater exposure of female germ cells to damaging environmental effects, including ionizing radiation (IR). Progress in paediatric oncology, based on the use of radiotherapy, also implies the occurrence of gonadal dysfunctions and subsequent female fertility disorders. Therefore, it seems justifiable to systematize the state of knowledge concerning the effect of IR on the female reproductive system. Brief description of the state of knowledge. A considerable part of studies concerning the effect of IR on female germ cells have been conducted on animals. Their extrapolation to humans is hindered because in animal studies high acute exposures are applied, which do not reflect human environmental exposures characterized by chronic low dose exposure. Studies on animals provide a heterogenous image, which hinders the formulation of unequivocal conclusions and indicates that radiosensitivity depends, i.a. on IR dose, stage of development of oocytes, the applied marker of the effects of IR, or on the species. LD50 of human oocytes is estimated to be below 2 Gy. The effect of IR depends, i.a. on the dose fractionation and the age (older women are more radiosensitive). In females, the effective sterilizing dose is: at birth 20.3 Gy, at 10 years 18.4 Gy, at 20 years 16.5 Gy, whereas at 30 years 14.3 Gy, which is associated with the available pool of ovarian follicles. Conclusions. Within the range of low doses received as a result of environmental exposure to IR, there is no evidence for the occurrence of either adverse pregnancy outcomes, nor fertility disorders in females. These effects may be related to the cancer radiotherapy, or exposure to high IR doses during nuclear accidents.

    INTRODUCTION: The results of direct surgical release of the median nerve in patients with carpal tunnel syndrome are frequently far from being satisfactory. Aim of the presented study is to assess the early results of bipolar pulsed radiofrequency (PRF) neuromodulation of the median nerve (MN) for treatment of carpal tunnel syndrome (CTS). MATERIAL AND METHODS: Fifteen adult patients with CTS (10 women and 5 men, mean age 58.5 years) were treated. The bipolar technique of neuromodulation was applied, with confirmation of the correct electrode position by neurophysiological examination. The study protocol included the Boston Carpal Tunnel Questionnaire (BCTQ), Numerical Rating Scale (NRS) for pain assessment and tip pinch strength assessment performed before neuromodulation as well as 4 and 12 weeks after treatment. Moreover, the sensory nerve conduction velocity (SNCV) was assessed before and 12 weeks after the intervention. RESULTS: A significant improvement in symptom severity (33.53 ± 8.25 at the baseline vs. 18.33 ± 11.06 and 25.67 ± 12.39 at 4 and 12 weeks) and functional status (21.0 ± 5.79 vs. 12.07 ± 7.20 and 17.73 ± 9.09) BCTQ subscores, as well as tip pinch strength (3.39 ± 1.68 vs. 5.86 ± 1.98 and 4.93 ± 2.22) were observed. A reduction in pain and improvement in SNCV were also found, but did not reach statistical significance. CONCLUSIONS: Bipolar PRF neuromodulation of MN is a promising therapeutic tool for patients with CTS and could potentially be an alternative to direct surgical release of MN. A longer follow-up period is required to assess the longevity of clinical improvement after the treatment.
    WSTĘP: Wyniki chirurgicznego odbarczenia nerwu pośrodkowego u części chorych z zespołem cieśni nadgarstka są niezadowalające. Celem pracy jest ocena wczesnych wyników leczenia zespołu cieśni nadgarstka (carpal tunnel syn-drome – CTS) za pomocą bipolarnej neuromodulacji nerwu pośrodkowego (median nerve – MN) z użyciem prądu o częstotliwości radiowej w trybie pulsacyjnym (pulsed radiofrequency – PRF). MATERIAŁ I METODY: Leczeniu poddano 15 dorosłych pacjentów z CTS (10 kobiet i 5 mężczyzn, średni wiek 58,5 roku). Zastosowano technikę bipolarnej neuromodulacji z użyciem prądu PRF. Prawidłowość położenia elektrod potwierdzano neurofizjologicznie. Protokół badania składał się z kwestionariusza objawów zespołu cieśni nadgarstka (Boston Carpal Tunnel Questionnaire – BCTQ), skali numerycznej NRS (Numerical Rating Scale) dla oceny bólu oraz oceny siły mięśniowej przed neuromodulacją oraz 4 i 12 tygodni po leczeniu. Ponadto oceniano szybkość przewodnictwa czuciowego w nerwie pośrodkowym (sensory nerve conduction velocity – SNCV) przed i 12 tygodni po interwencji. WYNIKI: Stwierdzono znamienną poprawę w zakresie podskal BCTQ dotyczących ciężkości objawów (33,53 ± 8,25 przed zabiegiem vs. 18,33 ± 11,06 i 25,67 ± 12,39 po upływie 4 i 12 tygodni od zabiegu) oraz stanu czynnościowego (21,0 ± 5,79 vs. 12,07 ± 7,20 i 17,73 ± 9,09), a także poprawę siły mięśniowej (3,39 ± 1,68 vs. 5,86 ± 1,98 i 4,93 ± 2,22). Ponadto stwierdzono redukcję bólu i poprawę SNCV, jednak parametry te nie osiągnęły znamienności statystycznej. WNIOSKI: Neuromodulacja nerwu pośrodkowego za pomocą prądu PRF przeprowadzona techniką bipolarną jest obiecującą metodą leczenia pacjentów z CTS i może być alternatywą dla chirurgicznego uwolnienia nerwu pośrodkowego. Dla oceny trwałości poprawy klinicznej po zastosowanym leczeniu konieczny będzie dłuższy okres obserwacji.
