Summary

Background/Aim: The loss of teeth and its consequences for health, as well as the psychological discomfort it entails, have a negative impact on both self-reported health state and quality of life (QoL). Dental implantation aims to increase patients’ health and satisfaction and to improve all aspects of QoL. The purpose of this cross-sectional correlational study was to compare the patients’ QoL before and after dental implantation.

Material and Methods: The study comprised 62 patients aged between 24 and 77, including 28 (45.16%) women and 34 (54.84%) men, who reported to a private dental clinic in Szczecin, Poland to replace missing teeth with implants. The survey was carried out twice: prior to the treatment, when the decision to use implants had been made, and three months after implantation, during the first check-up. QoL was measured using the 36-Item Short Form Health Survey (SF-36), and sociodemographic data were collected using a questionnaire of the author.

Results: There were statistically significant differences between the assessment of health and QoL before and after implantation treatment. Both the patients’ health and comfort of life improved after therapy.

Conclusions: Replacement of missing teeth with dental implants brought overall improvement in patients’ QoL, social comfort, and general health. Dental implantation should be recommended in the early phase of edentulism, after tooth loss.

Abstract

Introduction. The illness acceptance is one of the most effective strategies to cope with a chronic illness.

Aim. The purpose of this study is to recognize which factors determine and favor acceptance of a chronic illness, in regard to the personal resources of alcohol-dependent patients.

Material and methods. The study was conducted on 60 alcohol-dependent patients. During the study, the following research tools were used: Rosenberg’s SES questionnaire and AIS scale questionnaire.

Results and conclusions. The study group is characterized by an average level of acceptance of the disease. The level of self-esteem is an important factor in determining the level of acceptance of the disease in patients.

Abstract

The wing is the main aircraft construction element, whose main task is to produce the lift, balancing the aircraft weight as well as ensuring the execution of all flight states for which the aircraft was designed. The selection of appropriate airfoils or the development of new ones is one of the most important constructions goals. As a rule, constructors aim at ensuring a sufficiently large lift with little aerodynamic drag in order to increase the scope of utility angles of attack and such shaping of these characteristics so that the aircraft performance, close to the critical angles of attack, guarantees an adequate level of safety. One of the methods of improving the aerodynamic properties of airfoils is the Kline-Fogleman modification. It involves an application of a step into the airfoil contour at a place. It enforces the creation of a swirling air stream, preventing the separation and maintaining airflow over the profile and thus the reduction of drags, as well as delaying separation. The use of this type of a solution is justified when designing unmanned aerial vehicles, of small sizes, which move with slow speeds and sometimes-large angles of attack, including those close to critical angels of attack. The Kline-Fogleman modification decreases the likelihood of aircraft stalling.

The aim of this work is to present an analysis of airflow over NACA0012 airfoil with Kline-Fogleman modification. The calculations were made by solving the problem of numerical fluid mechanics. For calculations, the Comsol Maribor programme was used. The investigation focused on several different airfoil modifications (KFm-1, KFm-2, KFm-3). This enabled a selection of a solution, providing the most desirable aerodynamic characteristics.

Abstract

Personality traits, especially in sport are modulatory factors of athletes’ behavior – his/ her conscientiousness, the will to achieve an aim, perseverance and motivation of activity. Not only are biological predispositions related to anatomical or biochemical traits of success, but they are also largely determined by personality traits that result from genetic factors. In our research we joined tests of athlete’s personality in correlation with genotypes of the dopamine transporter (DAT1) gene polymorphism. The selection of this polymorphism was based on previous reports connecting the influence of dopamine with motivation and numerous arguments supporting its correlation with human behavior. We observed significant differences among polymorphisms DAT 9/9, 9/10, 10/10 in terms of proportion of particular genotypes between athletes and the control group. We also found significant differences in the NEO FFI sten scale for conscientiousness. We noticed that anxiety was related with genotypic variants of DAT1, specifically the 9/10 VNTR variant, which conditioned lower levels of anxiety in the group of tested athletes. By contrast, the lower sten value of agreeability was statistically significant for the group of athletes that were carriers of the 10/10 VNTR genotype. Heterozygous 9/10 VNTR among athletes showed lower levels of anxiety in comparison with the control group, whereas agreeability determined using the NEO FFI scale represented a lower value among athletes that had the 10/10 polymorphism. We may thus conclude that the presence of polymorphic variants of the dopamine transporter gene corresponds to athletes’ personality traits.

Abstract

Introduction. A review of Polish and international literature does not give a clear indication of the level of anaerobic capacity that sailors with disabilities demonstrate with regard to their functional capacities. This study sought to determine differences in functional capacity levels between sailors from three medical and functional groups. Material and methods. The research was carried out during a sports camp at the National Sailing Centre in Górki Zachodnie in 2014. Eighteen males with locomotor disabilities were included in the study. The athletes were members of the National Team of Sailors with Disabilities of the Polish Yachting Association. The sportsmen competed in the Skud 18 and 2.4mR Paralympic classes. A 30-second Wingate test for upper limbs was employed in the study. Results. Significant differences in mean power (MP) values were noted between the groups under investigation. The group of wheelchair sailors with improper core stability (A) and the group of wheelchair sailors with proper core stability (B) had significantly lower scores than the group of study participants who were able to move freely, that is to walk (C). Conclusions. The study revealed that a 30-second anaerobic capacity test performed on an arm ergometer differentiated disabled sailors from selected groups in terms of mean power. Research on anaerobic capacity may be used to verify the current classification in Paralympic sailing and will make it possible to differentiate present competition categories.
