The Dynamic Drawing Examination (DRV) is a method developed by István Hárdi, which holds a significant position in the history of the psychology of visual expression. Hárdi began to create this method in 1956 and developed it over 67 years. The DRV focuses on the dynamic process of clinical and drawing changes, distinguishing among various aspects including formal categories, content features, personality levels, and temporal changes. The method pays special attention to avoiding signes-fixed and prejudicial psychoanalytic interpretations. During the evaluation, participants are asked to create a human drawing, an animal drawing, and a free drawing, which are then assessed based on the principle of confrontation and comparative analysis. The DRV represented an important advancement in psychiatric and psychological diagnostics, as it was built on new perspectives instead of traditional approaches.

Összefoglaló. Bevezetés: A koronavírus elleni védőoltással kapcsolatos vélekedések igen aktuális, társadalmi szempontból fontos területét adják az egészségmagatartással foglalkozó kutatásoknak. Célkitűzés: Vizsgálatunk a védőoltásról különbözőképpen vélekedő (oltást elutasító, oltást választó, oltáson nem gondolkodó, valamint bizonytalan) csoportok elemzését tűzte ki célul az oltás előnyeinek és hátrányainak, valamint az információforrások használatának tekintetében. Módszer: A mintát "A koronavírus-járvány okozta lelki tényezők utánkövetéses vizsgálatának" 2020 decemberében felvett adatai adják; a vizsgálat során 1009 fő válaszait egyszempontos varianciaanalízissel elemeztük. Eredmények: Eredményeink azt mutatják, hogy a budapestiek és a Közép-Magyarországon élők, az idősebbek, a férfiak, a magasabb iskolai végzettségűek, valamint a házasok választják nagyobb eséllyel a védőoltást. Az oltásról különbözőképpen vélekedő csoportokat az oltás előnyei jobban elkülönítik egymástól, mint az oltás hátrányai. Az előnyök közül a csoportokat főképp a társas, társadalmi érdekekre fókuszáló tételek differenciálják, melyek a járvány megfékezéséről, a fertőzés átadásáról szólnak. A használt információforrásokat elemezve pedig elmondható, hogy mind a négy csoport jobban támaszkodik a személyes (család, barátok) és az orvosi, egészségügyből érkező információkra, mint a médiából érkező hírekre. Következtetés: Az oltási csoportok véleménye az oltás pozitív hozadékait, különösképp társadalmi hasznosságát illetően tér el, mely vélemények a leginkább a személyes kapcsolatokon, így az egészségügyi dolgozók álláspontján keresztül formálódnak. Tehát az egészségügyben dolgozóknak kiemelkedő szerepük van a hozzájuk tanácsért fordulók differenciált megértésében, szakértői tájékoztatásában és megfelelő tanácsokkal való ellátásában. Orv Hetil. 2021; 162(24): 931-937., Introduction: Beliefs regarding coronavirus vaccination provide very actual and socially important area in mental health research., Objective: The aim of our study was to differentiate the opinions related to coronavirus vaccination (acceptance, refusal, ignorance, hesitation). We analyzed advantages and disadvantages of vaccination, and the different channels in getting information about the vaccine., Method: Our study is part of the "Longitudinal examination of mental factors caused by the coronavirus epidemic" research project, wave of December 2020. We analyzed the responses of 1009 people by one-way analysis of variance tests., Results: Our results show that elder people, males, and those who have higher education are more likely to accept the vaccine. In addition, those who live in Budapest and Cental Hungary are more likely to choose vaccination against the coronavirus than those living in other areas. The groups with different opinions on vaccination are better discriminated by benefit-related than risk-related opinions. Those benefit-related items showed the largest variance between groups, which focused on social usefulness on curbing the epidemics, preventing the spread of the infection. Analyzing the sources of information, we found that all groups rely more on personal (family, friends) and medical health information than on news from the media., Conclusion: The opinions of the vaccination groups differ mostly regarding the positive benefits of vaccination, especially the social usefulness. Opinions are mostly formed through personal relationships including relations with healthcare workers. Healthcare professionals therefore have a key role in providing a differentiated understanding of those seeking advice, providing expert information and appropriate advice.

Introduction: Due to sedentary lifestyle, not only the risk of many chronic diseases and multimorbidity increase, but older people also lose their functional independency earlier. The first step to design effective interventions aiming to decrease sedentary lifestyle is to explore the factors associated with sedentary lifestyle., Aim: Our aims were to describe the type and duration of sitting activities and to examine the factors associated with sedentary lifestyle, namely 1) sociodemographic factors (i.e., age, gender, education level, marital status); 2) medical factors (chronic diseases, use of walking aids); 3) lifestyle factors (i.e., duration of institutionalization, smoking status) among older people living in nursing homes providing long-term care., Method: Data collected with questionnaire from 248 participants were analysed using logistic regression., Results: There were 159 participants (64.1%) in total who were characterized by sedentary lifestyle. In our sample, the sedentary lifestyle was associated with the smoking status, the number of age-related chronic diseases, the duration of institutionalization, and the use of walking aids., Conclusion: The older people who have more chronic diseases, who are smokers and were institutionalized earlier are more likely to be characterised by sedentary lifestyle. Therefore, decision-making graduate health-care professionals should preferably focus their efforts on these older people in order to change the sedentary lifestyle by providing information about risk of this lifestyle, and offering programs relevant to older people's interests and functional status.

The studies were focused on the corrosion stability of dental alloys (containing NiCr and stainless steel), for a possible release of Nickel (Ni). The investigations were carried out in artificial saliva at 37 degrees C. The potential range, where Ni dissolution may occur, was determined by transient measurements. It has been established, that: 1. Under in vivo conditions the probability of the pitting corrosion is very low. 2. The Ni release takes place on the temporarily damaged, locally activated parts of the surfaces.

The authors describe a computer analysable etiological card used for registration of data of Ni hypersensitive patients' with oral symptoms. The collection and evaluation of the data related to the pathological changes and predisposing factors can be useful in prevention of development of hypersensitivity or clinical symptoms of hypersensitivity in cases belonging to this risk group.
