Opis:
Introduction: Exercise at various durations and intensities impact on blood and stem cells. This pilot study examined the effects of 30 minutes of treadmill walking on hematological indices and progenitor stem cells CD34+ in healthy subjects. Materials and methods: A total of 17 non-smoking, healthy students, aged 20 to 22 years participated. Hemoglobin, hematocrit, white blood cells, platelets, and stem cell CD34+ numbers were assessed before and after moderate exercise. Statistical analyses examined the relationships between CD34+ cells versus hematological indices, age, and body mass index. Results: Following exercise, significant increases were observed in leukocytes, neutrophils, eosinophils, and CD34+ cells numbers. For CD34+ cells, a fourfold increase was seen. Significant correlations between CD34+ cells, white blood cells, and neutrophils were found. Conclusion: Our results suggest that moderate exercise has a physiological impact on hematologic parameters and stem cells CD34+ in healthy subjects. Furthermore, our findings suggest that brief treadmill exercise may enhance tissue repair mechanisms so important in physiotherapy.

Opis:
In the days of the visual culture a manner of the transmission of information plays a very important role. Adopting a technique of the join of text, graphics, sound and animation in frames of the uniform structure of presenting data, particularly in the education, it is possible to achieve good results in handing over of knowledge than at using only one of the media. The article presents the results of research devoted to the influence of visual and textual teaching materials, on the level of assimilation of knowledge subjects and their involvement in the assimilation of content. The analysis of the results showed that the visualization of teaching content is a factor significantly activating the educational process and affecting the level of knowledge assimilation.

Opis:
Over the last few decades, scientists exploring the aspects of engineering education and investigating the strong connection between the engineering profession and society have argued for a more rounded, holistic approach to the engineering curriculum. In addition to fundamental technical subjects, they have proposed the inclusion of a broad range of social subjects in order to equip young engineers with social and communication skills relevant for teamwork, and to enhance their awareness about both the way social changes influence the implementation of certain engineering solutions and about the way develop-ments in engineering have a considerable impact on society in general. This paper presents the results of a two-year qualitative study of the importance of social subjects within the engineering academic curriculum at the Faculty of Mechanical Engineering and Naval Ar-chitecture in Zagreb, Croatia.

Opis:
Introduction: The aim of the work was to evaluate one-time recording of ENG and VNG in healthy subjects selected for the given diagnostic tests with reference to the sensitivity and usefulness of this kind of testing in vertigo diagnostics. Material and methods: The tests covered 50 healthy subjects, including 24 women and 26 men aged 20-22 (the mean age of 20,5 years) who did not report any inconvenience from otorhinolaryngological organs and the conducted interview did not reveal any balance disorder or vertigo. Every patient underwent otoneurological subjective and objective tests, electronystagmography (ENG), including a calibration test, head-tracking test, optokinetic nystagmus test, rotatory chair test, positional tests according to Cawthorne and Rose, a Hallpike caloric test as well as videonystagmography which included a calibration test, spontaneous nystagmus evaluation, head-tracking test, positional tests according to Cawthorne and Rose with a head rotation test and Hallpike caloric test. The above tests were performed separately, 24 hours one by one. One-time recording of ENG and VNG was made 48 hours following the last test while each of the two tests was preceded by an additional calibration test. The final recording included the spontaneous nystagmus evaluation, positional tests according to Cawthrone and Rose together with the head rotation test and Hallpike caloric test. Results: Any negative mutual influence of the conducted tests has not been observed. Both in the one-time and separate recording, the caloric test revealed lower values of the mean velocity of the nystagmus free phase in ENG with relation to VNG. No signs from spontaneous nystagmus, as well as optokinetic and positional nystagmus, could be found in any case. Conclusions: The conducted tests did not show any possibility of mutual exclusion of the given ENG and VNG diagnostic tests one-time recording. However, their use in diagnostics of balance disorders and vertigo requires further studies

Opis:
Two human clinical studies were performed. One was an open-label non-controlled study involving 30 healthy female subjects for 8 weeks. Significant improvements were observed by combining 6 mg per day oral supplementation and 2 ml (78.9 μM solution) per day topical application of astaxanthin. Astaxanthin derived from the microalgae, Haematococcus pluvialis showed improvements in skin wrinkle (crow's feet at week-8), age spot size (cheek at week-8), elasticity (crow's feet at week-8), skin texture (cheek at week-4), moisture content of corneocyte layer (cheek in 10 dry skin subjects at week-8) and corneocyte condition (cheek at week-8). It may suggest that astaxanthin derived from H. pluvialis can improve skin condition in all layers such as corneocyte layer, epidermis, basal layer and dermis by combining oral supplementation and topical treatment. Another was a randomized double-blind placebo controlled study involving 36 healthy male subjects for 6 weeks. Crow's feet wrinkle and elasticity; and transepidermal water loss (TEWL) were improved after 6 mg of astaxanthin (the same as former study) daily supplementation. Moisture content and sebum oil level at the cheek zone showed strong tendencies for improvement. These results suggest that astaxanthin derived from Haematococcus pluvialis may improve the skin condition in not only in women but also in men.

In a specific manifestation in public administration, coordination is vigorous activity of the subject that stipulated the disclosure of its essence through the managerial relations thesaurus and its related categories: managerial interrelations, managerial interaction, managerial communications. It is proved that for the public administration system the most appropriate classification is the division of managerial relations, depending on the way of achieving the end result of public authorities staying in relations: subordinated, coordinative, reordinated.

W artykule podjęto próbę przybliżenia problematyki społecznego wartościowania pracy zawodowej nauczycieli, ze szczególnym uwzględnieniem specyfiki ich funkcjonowania w środowisku wiejskim. W tekście zaprezentowano przemiany społecznych oczekiwań wobec nauczyciela w środowisku wiejskim w świetle literatury, a następnie dokonano prezentacji wyników własnych badań nad społecznymi oczekiwaniami wobec pracy nauczycieli na wsi w wymiarze temporalnym. A zatem, jak praca ta jest postrzegana przez podmioty edukacyjne będące w różnym wieku, a także, co się z tym wiąże, znajdujące się w innym usytuowaniu czasowym swego życia (cyklu życia), jak i czasu historycznego (pokolenia): uczniów, studentów kierunków nauczycielskich wywodzących się ze wsi, rodziców oraz dziadków i innych mieszkańców wsi.
The article is an attempt to present the issues of social evaluation of teachers’ professional work, with particular emphasis on the specificity of their functioning in a rural environment. The text presents the changes in social expectations towards teachers in rural areas in the light of literature and then shows the results of the author’s own research on social expectations towards teachers’ work in rural areas in a temporal dimension, which includes the presentation of how their work is perceived by education subjects of different age and, therefore, in different times of their lives (life cycle) and historical time (generation): pupils, students of teaching faculties coming from rural areas, parents and grandparents, as well as other inhabitants of rural areas.

Opis:
The article presents the proposal for rules for granting a pass out of mathematics for business studies. The proposed schema guarantees that each student demonstrates a mastery of all the required skills, not only 60 or 70 percent as at the traditional exams. The proposed organization also eliminates the need for time-consuming repeated checking solutions of similar tasks written by the same student. The idea of the assessment procedure is based on two rules: (1) students must demonstrate that they have mastered all the required knowledge and all the skills, having three attempts; (2) each subsequent attempt includes only the previously failed topics. The proposed system was introduced on a trial basis at the Faculty of Management at the University of Warsaw, where it was subject to the assessment of circa 150 students. The conclusions and examples of students’ comments have been provided in the article.

Opis:
For workers such as police motorcyclists or couriers, traffic and engine noise reaching the ears is an important factor contributing to the overall condition of their work. This noise can be reduced with motorcycle helmets. In this study, insertion loss of motorcycle helmets was measured with the microphone-in-real-ear technique and sound attenuation with the real-ear-at-threshold method. Results for 3 Nolan helmets show essentially no protection against external noise in the frequency range <250 Hz. In the frequency range >500 Hz, attenuation increases linearly at a rate of 8–9 dB per octave, to ~30 dB at 8 kHz. Lack of attenuation in the low-frequency range may cause annoying effects. In addition, high attenuation in the high-frequency range may decrease intelligibility of speech signals for a rider in a helmet. Attenuation measured in this study does not take into account noise generated by turbulent wind around the helmet. Thus, the measured values of attenuation represent a motorcycle rider’s best conditions of hearing.
