Opis:
Oral cavity lesions are amongst the earliest manifestations of HIV-infection. Thorough examination of oral cavity as well as awareness of associations between specific symptoms and HIV-infection can lead to early diagnosis of this life-long disease. Consequently, early diagnosis of HIV infection allows for prompt introduction of antiretroviral therapy allowing to improve patients’ quality of life, their life expectancy but also reducing the risk of transmission. Therefore, raising awareness on oral cavity disorders suggestive of HIV-infection among general physicians and dentists is of a great importance. In this article we described the most common oral cavity manifestations associated with HIV infection including: oral candidiasis, hairy leukoplakia and Kaposi’s sarcoma in detail.

Opis:
Malignancies were one of the earliest diagnosed manifestations that resulted in the description of acquired immunodeficiency syndrome (AIDS). Most cancers in AIDS patients are associated with coinfection with oncogenic viruses. Knowledge and public awareness about HIV infectious materials are important elements in preventing the spread of HIV infections. The aim of the study was to assess the knowledge about HIV infectious materials among three populations in Poland. A Poland-wide on-line survey was conducted and 2205 anonymous answers were analysed. Almost half of the answers came from students, of which 40% were medical students.

Opis:
Sexually transmitted infections (STIs) spread through sexual contact and can be responsible for many clinically significant complications, such as pelvic inflammatory disease, infertility, ectopic pregnancy, fetal or neonatal death, premature delivery and increased susceptibility to HIV infection. Worldwide, millions of cases of STIs, such as chlamydia, syphilis or gonorrhoea occur every year, and hundreds of millions of people are currently infected. Some STIs can be cured following appropriate therapy. Others cannot be completely cured, but medicines can be used to manage symptoms and prevent ongoing transmission. According to the World Health Organization, STIs are one of the five types of diseases for which adults most commonly seek medical support worldwide. In this paper, we present the results of the analysis of data collected in Poland on the awareness of Polish society about sexually transmitted infections.

Opis:
Heavy-duty, oil-cooled brake discs (MMOTs) are often used in heavy-duty brake systems manufactured by companies such as Caterpilar, Clark, Komatsu and Liebherr. These discs are usually made of special steels, and in most cases, the flatness of the working surfaces should not exceed 0.15–0.30 mm. Although the technological processes of friction disc production include several stages of heat treatment and grinding, the required accuracy is not achieved in some cases. In addition, the remaining residual stresses lead to the deformation of the discs during their lifetime. In production practice, three methods are used to reduce residual stresses: thermo-fixing, dynamic stabilisation and vibratory stabilisation consisting in bringing discs to transverse resonance vibrations and maintaining resonance until significant stress reduction. The article proposes a method of stabilising the discs using the resonance phenomenon at the first few frequencies. In this article, Cauchy’s function method and characteristic series method are used to develop solution value problem for clamped circular plates with discrete inclusions as concentrated masses and springs. Calculation methods for quick estimation of the own frequency of discs with additional ring mass enabling the use of low power vibration inductors are presented. The use of a special membrane and a pneumatic cushion in the construction of the stand allows to induce vibrations of higher frequencies.

Opis:
Sexuality is a significant pillar of a romantic relationship, and sexual satisfaction is closely related to the stability of the relationship as well as satisfaction associated with it. The aim of this paper was to briefly characterize the sex life of Poles, especially regarding safe sex, sexual assertiveness and satisfaction with sexual life. A Poland-wide on-line survey was conducted between January and March 2019. 2205 anonymous answers were analyzed. To compare the knowledge of heterosexual and non-heterosexual persons, medical students were excluded from both groups. We identified three studied populations: heterosexuals excluding medical students, non-heterosexuals excluding medical students and medical students. Participants were asked for taking a stance to a few statements. The majority of respondents declared that their sexual contacts are always as safe as they want and they can easily refuse sexual contact with another person. Furthermore, most of the respondents were also satisfied with their sex life, especially the group of medical students.

HIV testing
Opis:
The first people were infected with HIV in the early twentieth century. However, due to the non-specific clinical symptoms and long asymptomatic period of infection, the world became aware of the virus only many years later. HIV testing is one of the basic elements of HIV prevention. Other elements include the use of condoms, pharmacological prophylaxis and, in the case of infection, antiretroviral treatment. Knowledge of places where it is possible to get tested for HIV in a free way and basic information about tests seem to be important in reducing HIV transmission. In this work respondents from Poland were asked a few questions about HIV testing.

Opis:
Viral hepatitis is caused by viruses, the most important of which are hepatitis A virus (HAV), hepatitis B virus (HBV) and hepatitis C virus (HCV). New discoveries and new therapeutic options result in better and better results of treatment. However, the public's awareness of the occurrence of these diseases and the detection of infections as soon as possible is still important, what is associated with better outcomes. In order to assess the basic knowledge about viral hepatitis among Polish society, an online survey spread throughout Poland and covering mainly young people was created. 2205 responses were collected and analyzed. On the basis of the results obtained, it can be concluded that Polish youth have little knowledge about viral hepatitis, what is associated with less awareness of the possibility of infection.

Opis:
W pracy zaprezentowano wybrane aspekty badań pokryć antykorozyjnych elementów maszyn. Omówiono komorę solną, która jest wykorzystywana w metodzie sprawdzania pokryć antykorozyjnych. W komorze rozpylony został chlorek sodu. Jego zadaniem jest pokazanie, która powłoka spełnia wymagania oraz która powinna zostać jeszcze dopracowana (znalezienie przyczyny odpowiedzialnej za negatywny wynik badania). Jest to badanie, które wykonuje się w temperaturze 35°C i 5% NaCl w atmosferze. Badania w rozpylonej obojętnej solance (NSS) przeprowadzone są wg PN-EN ISO 9227 oraz ISO 3574. W pracy przedstawiono wyniki badań pomiarów próbek, które zostały podzielone ze względu na technologie przygotowania powierzchni, śrutowanie, producenta farby, grubość powłoki oraz stopień odwarstwienia.
The paper presents selected aspects of testing corrosion protection of machine elements. The salt chamber is discussed, which is used in the method of checking anti-corrosion coatings. Sodium chloride was sprayed into the chamber. His task is to show which coating meets the requirements and which should be further refined (finding the reason responsible for the negative test result). This is a test that is performed at 35°C and 5% NaCl in the atmosphere. Tests in atomized neutral brine (NSS) are carried out according to PN-EN ISO 9227 and ISO 3574. The paper presents test results of sample measurements, which were divided by surface preparation technologies, shot blasting, paint manufacturer, coating thickness and degree of detachment.

Opis:
Efforts of the scientific community led to the development of multiple screening approaches for COVID-19 that rely on machine learning methods. However, there is a lack of works showing how to tune the classification models used for such a task and what the tuning effect is in terms of various classification quality measures. Understanding the impact of classifier tuning on the results obtained will allow the users to apply the provided tools consciously. Therefore, using a given screening test they will be able to choose the threshold value characterising the classifier that gives, for example, an acceptable balance between sensitivity and specificity. The presented work introduces the optimisation approach and the resulting classifiers obtained for various quality threshold assumptions. As a result of the research, an online service was created that makes the obtained models available and enables the verification of various solutions for different threshold values on new data.
