Hvaležnost obdarjenca – pravna in moralna obveznost
Authors: Dimitrijević Miloš
Published: March 2023

Pričakovana (in zahtevana) hvaležnost obdarjenca, ki je utemeljena z neodplačnostjo darilne pogodbe, se najbolj izrazito kaže v obliki preklica darila zaradi hude nehvaležnosti. Darovalec lahko prekliče darilno pogodbo zaradi hude nehvaležnosti, če se po njeni sklenitvi obdarjenec proti njemu ali njegovemu bližnjemu obnaša tako, da bi bilo po temeljnih moralnih načelih nepravično, da bi obdarjenec prejeto obdržal. Upoštevaje težavnost opredelitve darila ter primerjalnopravno neenotnost ureditve daril in neodplačnih pravnih poslov, ne preseneča, da se pri uporabi instituta preklica darila zaradi nehvaležnosti pojavljajo praktične težave. Te izhajajo iz neopredeljenega teoretičnega izhodišča, najizraziteje pa se kažejo pri remunatoričnih darilih, darilih danih iz drugih posebnih nagibov,
ter v okoliščinah, v katerih je obdarjenec svojo moralno obveznost hvaležnosti že izpolnil. Sociološki in antropološki zaključek je, da je družbeni pojav dajanja, prejemanja in vračanja daril odvisen od konteksta (okoliščin) primera, predvsem pa vseh kompleksnosti razmerja med konkretnim darovalcem in konkretnim obdarjencem. Zdi se, da pravni
sistemi neuspešno poskušajo uporabiti splošne pogodbenopravne (tržne) režime na darilih, ki so nedvomno, zunajtržna in s tem v bistvenem nepogodbena kategorija. Posebna pravila, ki naj bi odražala posebnost daril kot neodplačnih pravnih poslov, so pravzaprav zgolj izraz nezaupljivosti prava do daril. Bistveno odprto vprašanje je, ali je ta nezaupljivost utemeljena ali pa je zgolj posledica zastarelih zgodovinskih teoretičnih izhodišč.
The European Union after the Crisis: Risks and Opportunities—The Problem of “Uncomfortable Knowledge” and “Institutionalised Forgetfulness”
Authors: Straus Joseph (Jože)
Published: March 2023

The crisis caused by the war in Ukraine and the COVID-19 pandemic constitutes the most serious challenge for Europe since World War II. The crisis threatens Europe’s security and economy to an unprecedented level. No prediction on when and how the crisis will end is possible. However, irrespective of its end, there is no doubt that for Europe, it will generate costs amounting to several hundreds of billions if not even some trillions of Euros, i.e. seriously harm and weaken the European economy and endanger Europe’s position as a global economic power. It will also result in fundamental changes of international economic and political relations. Searching for, working on and designing rational and effective solutions to successfully master the aftermath of the crisis politically and economically should have a priority for the European Union, coming next only to the incredibly challenging efforts to master the ongoing crisis. The COVID-19 pandemic as well as the war in Ukraine caught the EU by surprise and unprepared. Europe should avoid such an experience in the future. Regardless of how this crisis will end, mastering
its aftermath and identifying the respective risks and opportunities of the EU will have to start with identifying the main beneficiary(ies) of the crisis and analysing its (their) treatment of the EU and its Member States before and during the crisis. This will not be possible by limiting the actions to the day-to-day business, such as finding new suppliers for raw materials and energy, harmonising fiscal rules, providing the necessary funds to
master the financial crisis, etc. A much broader visionary approach will be necessary to find solutions for sustainable peace in Europe. An outcome such as that of the Treaty of Versailles should be avoided. One should prevent the “sleepwalkers” of today, i.e. those ignoring the “uncomfortable knowledge”, letting Europe slide into World War III. The
EU should make it clear to all of its Members, for Europe, the “European Solidarity’, with all of its attributes, constitutes the core of the EU’s genuine interests, including those of security and defence. This will require also amendments of the TEU and TFEU discussed in this paper. Otherwise, the EU and its Members will never acquire the status of an equal animal—in the global context—i.e. become truly sovereign and independent.
Association of Reproductive Parameters with Dermatoglyphics in Breast Cancer Patients, Healthy and High-Risk Individuals
Authors: Rangan Rahul , Shedge Swapna , Kakade Satish
Published: March 2023

Background
Breast cancer has a wide array of risk factors, and its confounding reproductive aetiologies have been paramount in defining the predictive ability of the disease. Similarly, a strong link between qualitative dermatoglyphic patterns and predisposition to breast cancer has been well documented through genetic linkage. Therefore, this study aimed to discern the affiliation between the aforementioned risk factors of breast cancer. 
 
Methods
The study was carried out in 3 groups of 90 age-matched individuals of - breast cancer patients, high-risk individuals and healthy individuals. A detailed reproductive history was taken including factors such as age at menarche, menstrual regularity, age at menopause (if attained), breastfeeding, obstetric parameters and age at first live birth. Qualitative dermatoglyphics were procured through the standardised ink and paper method to get a remarkable rolled fingerprint. The variations in gynaecological and obstetric parameters and qualitative dermatoglyphic patterns were studied and their significance was computed using the chi-square test on InStat software where p values < 0.05 were considered significant with a 95% confidence interval.
 
Results
Highly significant values (p<0.0001) were found in all gynaecological and obstetric parameters where a higher frequency of whorls in breast cancer patients, arches in high-risk individuals and an equivalent frequency of arches and whorls were predisposed to healthy individuals.
 
Limitations
Although this study might have identified certain predominating patterns with higher frequency, the consistency might vary from place to place due to differing dermatoglyphics according to ethnicity. 
A small number of patients receiving chemotherapy experienced - chemotherapy-induced adermatoglyphia - where the loss of fingerprints or very faint fingerprints was difficult to perceive. These patients were not included in the study to ensure maximum efficacy in interpreting the dermatoglyphics.
 
Conclusion
Previous attempts failed to link dermatoglyphic indices and reproductive parameters, this study found a significant correlation between the variables in the three distinct groups. Most breast cancer patients are diagnosed late with a majority presenting to doctors in advanced stages where survival rates are marginal, so by this method, we can get a simple, practical, non-invasive and easily affordable screening technique for the above risk factors. This technique could also be employed for non-symptomatic women who might have a positive family history of breast cancer as a part of risk assessment for early diagnosis and treatment. Therefore, paving way for further research into the prognostic abilities of gynaecological parameters through qualitative dermatoglyphic indices.

Published: March 2023

Background: One of the leading cause of death in Thailand is coronary artery disease (CAD). There are several studies that demonstrated a significant correlation between diagonal earlobe creases (DELC) or Frank’s sign and CAD, but data in Thai populations still remains unclear. Because of Frank’s sign is easily to observe by health-care professional including medical students, so it was very interesting to use to identify risk of atherosclerosis of the patients in hospital which has limitation of resources. The purpose of the study was to assess the prevalence of Frank’s sign and evaluate the diagnostic accuracy in CAD among the angina chest pain patients at Lampang Hospital.
Methods: This study was a cross-sectional, observational, study. Three hundred and nine patients with angina chest pain who underwent coronary angiography (CAG) and followed up at the coronary clinic at Lampang Hospital were enrolled in the study. Both ears of the patients were inspected for Frank’s sign. The accuracy of Frank’s sign was confirmed by three cardiologists and clinical data was collected in medical record form. We excluded the patients whose earlobe could not be clearly observed, including those with keloid/ulcer on the earlobe or those with no earlobe. The correlation of Frank’s sign and CAD were analyzed by using logistic regression and receiving operative curve (ROC) curve.  
Results: 64.4% of the angina chest pain patients (N=199) have demonstrated for Frank’s sign, unilateral Frank’s sign in 12.3% (N=38) and bilateral Frank’s sign in 52.1% (N=161). Twenty-one patients (6.8%) were normal CAG and 288 patients (93.2%) were significant CAD, single vessel disease CAD (N=86), double vessel disease CAD (N=83) and triple vessel disease CAD (N=119). The diagnostic accuracy of the Frank’s sign revealed that 64.6% for the sensitivity and 38.1% for the specificity. Besides, the positive predictive value (PPV) was 0.935 and for negative predictive value (NPV) showed 0.073. Nevertheless, the positive likelihood ratio (LR+) was 1.032 and 0.947 for the negative likelihood ratio (LR-). Moreover, the area under the curve (AuROC) of Frank’s sign with respect to detection of CAD was 0.513 (95% Confidence Interval was 0.385-0.642, P= 0.838).
 
Conclusion: Frank’s sign was observed in two-third of angina chest pain patients at Lampang Hospital and mostly of the patients with Frank’s sign were significant CAD. The results of this study showed that Frank’s sign was a simple, non-expensive and non-invasive method for medical student and health-care professional to identify risk of CAD.

Published: March 2023

Background: World Health Organization (WHO) verified 780 cases of monkeypox across 27 countries between 13 May 2022 and 2 June 2022. The World Health Organization (WHO) classified the growing worldwide monkeypox epidemic a PHEIC on July 23; the bulk of confirmed cases have been found in European locations. The purpose of this research is to assess the level of awareness toward human monkeypox virus among the Syrian medical students, general practitioners (GPs), medical residents, and specialists.
Methods: We performed a cross-sectional online survey in Syria between 2 may and 8 September, 2022 to assess medical students', general practitioners', residents', and specialists' knowledge about the monkeypox virus. The utilized tool was developed with input from the World Health Organization, the Centers for Disease Control and Prevention, and cross-sectional studies conducted in Indonesia. The survey has 53 questions divided into three groups: demographic information, work-related details, and monkeypox knowledge. The time-efficient and simple snowball method of sampling was used. Version 28.0 of SPSS was used to analyze the data.
Results: A total of 1257 healthcare workers and medical students throughout all of Syria's governorates took part in the research. The percentage of responders who learned anything about monkeypox in medical school was just 6.2% (n = 78). As a whole, students scored 10.23 out of a possible 15, with 11 being the adequate level for knowledge. About half of the participants (n = 700) are familiar with the term "monkeypox." As well, half of the respondents (n = 663) just learned about monkeypox during the last few days, while almost half (n = 530) only learned about it within the past month. Almost participants didn't know adequately about monkeypox. The natural host and incubation time for monkeypox were correctly identified by just 2.7% of responders and 33.3% of the whole population, respectively. 1.8% of participants gave the right response when asked about the symptoms of monkeypox. Sixty percent of the study sample think the symptoms of monkeypox and smallpox are identical. The females had higher knowledge toward monkeypox (aOR = 1.5, 95% CI = 1.26-1.80, p<0.001) than males. Respondents who are specialist doctors had higher knowledge toward monkeypox (aOR = 2.96, 95% CI = 2.24-3.92, p<0.001) than others.
Conclusion: Due to the critical lack of knowledge about monkeypox among Syrian clinicians and undergraduate medical students, urgent action to solve this local issue is required. Therefore, education and awareness regarding monkeypox vaccinations are of paramount importance. In order to improve the medical community's capacity to respond to human monkeypox cases and report them into a disease surveillance system, it is crucial that doctors have a better understanding of the illness.

Authors: Alibrahim Hidar , Swed Sarya , Bohsas Haidara , Shoib Sheikh , Alsakka Shahm , Jawish Nagham , Alabdeen Othman Zain , Sawaf Bisher
Published: March 2023

Background: After the widespread of COVID-19 around the globe, it was imperative to establish preventative measures to restrict the virus's transmission and enable clinicians to remotely monitor patients' status and avoid direct contact with them. The purpose of this research was to present an overview of the awareness, knowledge, attitude, and abilities of Syrian physicians about telemedicine technology.
Methods: An online cross-sectional study was conducted from 1 April to 15 May, 2022 to assess Syrian doctors' awareness, knowledge, attitude, and skills towards telemedicine. The questionnaire was taken from published study, and the inclusion criteria consist the Syrian doctors who worked in hospitals during the COVID19 pandemic, mainly those who had direct contact with patients. Data were analyzed using descriptive and multivariate logistic regression analysis in IBM, SPSS V. 28.0.
Results: Among 385 responses, 52.72% of them were females, 83.9% of them were aged less than 30 years old, and 66% were working in the governmental sector. 66% of participants have moderate knowledge about using computers and the internet, 80% have heard about telemedicine. Despite that, 95.1% of participants have not attended any training workshop on telemedicine, and most of them have reported no availability of a telemedicine unit in their department. Only 31.7% participants have shown high awareness of telemedicine. Furthermore, no significant correlation was identified between the academic level with the age and telemedicine awareness, knowledge, attitude, or computer skills. Despite that, there was an obvious correlation between age and computer skills (P Value<0.05). There was a significant correlation between the medical specialty and awareness, and computer abilities, especially the anesthesiology (88.5±5.2), (84±8.7) respectively.
Conclusion: The study results demonstrate that most of the participating clinical doctors have a neutral view of telemedicine, even though they don't know much about it and don't have considerable experience with it. It is practical to educate and train academic staff, practicing physicians, residents and medical students within the clinical stages about telemedicine.

Dieser Band beschreibt, wie der Mobilitätsalltag von Einkommensarmen aussieht. Präsentiert werden Ergebnisse des von der Deutschen Forschungsgemeinschaft geförderten Projekts MobileInclusion. Auf Grundlage von 40 qualitativen Interviews mit „Hartz IV“-Beziehenden und einer räumlichen Analyse wird die Verbindung zwischen subjektiver Wahrnehmung und objektivierter Erreichbarkeit in Berlin und Hamburg hergestellt. Das ÖPNV-Angebot ist überdurchschnittlich, wird allerdings in dicht bewohnten Gebieten durch große Nachfrage (über-)kompensiert. Wesentliches Hemmnis für Befragte ist nicht die Taktdichte, sondern der Fahrpreis. Zentral ist außerdem ihr Möglichkeitsraum, also vorstellbare Mobilität. Einige können keine Wunschziele außerhalb des Aktionsraums (mehr) benennen, andere nennen Ziele weit jenseits des Alltäglichen. Letztere leiden am meisten unter eingeschränkter Mobilität. Aus den Ergebnissen werden drei politische Strategien entwickelt, um Möglichkeitsräume für Betroffene zu erweitern.
Academic-Support Environment Impacts Learner Affect in Higher Education
Authors: Voisin Lindsey E. , Phillips Casey , Afonso Veronica M.
Published: March 2023

Unlike university classrooms, academic support services provide students opportunities for enactive mastery of a skill with immediate feedback in a low-risk learning environment. Given that this environment likely alters affective states, this study tracked support-seekers’ perception (n=107) of their anxiety and confidence before and after repeated 1 hour academic skill development sessions (n=384). Results showed that academic-support environment had a robust, immediate, and long-lasting effect on decreasing anxiety and increasing confidence. Positive outcomes such as reduced anxiety and increased confidence during an academic skill development session were associated with increased academic performance. There was a high rate of participants (98%) persisting into the next year of their program. Together this study demonstrates that the academic-support environment can provide intervention in the form of enhancing affective states in situations of high anxiety and low confidence to potentially affect academic outcomes and retention rates.

Published: March 2023

Australian university students who are the first in their family to attend university are more likely to encounter challenges in their transition to university, and programs to support students are important for success and retention. Fifteen first-in-family (FiF) students participated in an Australian-first pilot orientation program. Program students had better engagement (attendance and study hours) and higher grades compared to a control group. There were no group differences in self-efficacy, program participants had steady social support over time while the control group experienced a decline across semester 1. Qualitative findings indicate that participants felt confident about their transition and did not report academic challenges. They had made connections and felt supported. Commute times were the most common adjustment reported.

El notario en el siglo XXI
Authors: Gomá Lanzón Ignacio
Published: March 2023

No es fácil explicar a un lego a qué se dedica exactamente el notario. La abstracción de su función —que opera con la idea de la confianza y las presunciones jurídicas—, su conformación histórica por accesión de funciones y su particular naturaleza híbrida público-privada no permiten encajarlo en los moldes profesionales habituales. A su origen como redactor de contratos se le añade con el tiempo la fe pública y la conservación de los documentos; más tarde, el asesoramiento y el control de legalidad. Con la Ley de 1862 se fija su estatuto actual, que se desarrolla exitosamente en el siglo xx. En el siglo xxi se han señalado ya varias líneas de transformación: la extensión del valor intrínseco del instrumento público; la evolución tecnológica del documento y corporativa; el nacimiento del concepto de regularidad material; nuevas funciones en materia de jurisdicción voluntaria, y nuevas funciones del notario en su actuación profesional en general y en el asesoramiento en particular.

An integrated optimization for minimizing the operation cost of home delivery services in O2O retail
Authors: Wang Xu , Zhong Jian
Published: March 2023

During the spread of the epidemic, the home delivery service (HDS) has been quickly introduced by retailers which helps customers avoid the risk of viral infection while shopping at offline stores. However, the operation cost of HDS is a huge investment for O2O retailers. How to minimize the operating costs of HDS is an urgent issue for the industry. To solve this problem, we outline those management decisions of HDS that have an impact on operating costs, including dynamic vehicle routing, driver sizing and scheduling, and propose an integrated optimization model by comprehensively considering these management decisions. Moreover, the dynamic feature of online orders and the heterogeneous workforces are also considered in this model. To solve this model, an efficient adaptive large neighborhood search (ALNS) and branch-and-cut algorithms are developed. In the case study, we collected real data from a leading O2O retailer in China to assess the effectiveness of our proposed model and algorithms. Experimental results show that our approach can effectively reduce the operating costs of HDS. Furthermore, a comprehensive analysis is conducted to reveal the changing patterns in operating costs, and some valuable management insights are provided for O2O retailers. The theoretical and numerical results would shed light on the management of HDS for O2O retailers.
Pricing and coordination of remanufacturing supply chain considering remanufacturing capacity and preferences under government mechanisms
Authors: Feng Yanhua , Yu Shujun
Published: March 2023

The management of recycling and remanufacturing supply chains, which can help enterprises achieve low pollution, low energy consumption and sustainable development, has become a new strategy of modern enterprises. The factors of supply chain and government mechanisms will have an impact on enterprise decisions for recycling, remanufacturing and social welfare. In order to promote the sustainable operation of the supply chain, considering the coordination role of government mechanisms and supply chain, a recycling and remanufacturing supply chain model composed of a manufacturer, retailer and recycler is constructed. This paper discusses the pricing decision of new/remanufactured products, supply chain performance level, such as remanufacturing effort, publicity service efforts and profit, and social welfare in five models of three situations: centralized situation, including non-government mechanisms and non-supply chain coordination; manufacturer-led situation, including non-government mechanisms and non-supply chain coordination, government mechanisms and non-supply chain coordination, government mechanisms and supply chain coordination; government-led situation, including government mechanisms and non-supply chain coordination. It is found that under manufacturer-led situations, the government subsidy and bonus-penalty mechanisms can encourage manufacturer and retailer to actively participate in the recycling and remanufacturing activities. The supply chain coordination contract can further enhance the role of the consumer market and promote the implementation of government mechanisms. Manufacturer adopts a cost-sharing contract to encourage recyclers to carry out recycling activities. Under certain conditions, the contract can effectively improve the benefits and social welfare. The research conclusions have important theoretical and practical application value for the coordination and cooperation among enterprises in the supply chain and the formulation of government mechanisms.

Predictors of Length of Care in Tibial Fracture Patients: Analysis of Secondary Data
Authors: Hakam Mulia , Pratama Fernanda Reza , Ridla Akhmad Zainur
Published: March 2023

Introduction: Predicting the length of care becomes important for intervention in the care system. However, it still seems that the ability to predict the length of treatment is not optimal, so that the length of treatment is prolonged. If the ability to predict the length of treatment can be done optimally, it will improve the patient's return time.

Methods: This study uses a retrospective study approach.

Result: There was no relationship between the predictor of length of stay with a length of treatment.

Conclusion: The predictor of length of stay in this study were patients with tibia fractures at RSD dr. Soebandi. Most of the patients with tibial fractures were in the early elderly, with the gender of patients with tibia fractures being mostly male. Most of the patients with tibial fractures have no complications and the type of fracture in patients with tibia fractures is mostly in the fracture of the shaft of the tibia. There was no correlation between the predictors of length of stay and length of stay in patients with tibia fractures.

"This paper aims to highlight the devastating impact of the imposed restrictions during the COVID-19 Pandemic towards the mental health of the sailing crew. It is well known that the employees in the navy domain were already accustomed to distinct working conditions, depriving themselves of factors that are vital for a balanced, functional state of mental health. The seamen are subjected to solitude, uncertain and unpredictable weather, a constant fear of danger and the anxiety of being prepared to ensure their own safety at any time needed. This paper aims to highlight the devastating impact of the imposed restrictions during the COVID-19 Pandemic towards the mental health of the sailing crew. Isolation, research shows, has an impact on both mental and physical health, from reducing the ability to manage stressful situations, to difficulties in making decisions, memorizing and processing information to the onset of depression, anxiety, attacks of panic and increasing the risk of illness, because the immune system of a person responds differently in the fight against viruses. In this paper were presented the procedures that the crew members of the ships that made voyages in the areas where the imposed restrictions were among the toughest to follow. Also, the mental state of the crew during the voyage and after arrival were analyzed, from in terms of the staff's statements but also individually."

"Refrigeration is an industry of high importance in our modern times. It plays also a key role in maritime transport of perishables, where vapour compression refrigeration systems are dominant. These energy systems are indispensable, but they should be wise exploited because their high energy necessity. One of the frequent refrigerant chemical adopted in this system is the hydrofluorocarbon R134a. This refrigerant came to substitute traditional refrigerants, such as chlorofluorocarbons or hydro chlorofluorocarbons – substances being under environmental regulations. In this study, it is approached a single stage vapour compression refrigeration system working with R134a. The aim is to find the conditions in which this system is more energy efficient. In this respect, based on the laws of thermodynamics, are obtained information on Coefficient of Performance and energy destruction trends – when the evaporator temperature increases. Our results indicate that, although the analysis based on the first law of thermodynamics reveals that the performance of the system is higher for high evaporator temperatures, the energy destructions in this system increase together with the evaporator temperature increase.

Do Current Pre-Exercise Fluid Recommendations for Athletes Need to be Updated? A Short Review
Authors: Kostelnik Samantha , Valliant Melinda
Published: March 2023

Introduction: Maintaining adequate hydration throughout the day is extremely important, especially for the athletic population. While several recommendations have been developed to aid in timing (i.e., before, during and after exercise) and quantity of fluid intake, research has shown that approximately 70% of collegiate athletes arrive to practice in a dehydrated state. This review aims to identify the studies that have developed fluid protocols or utilized fluid recommendations for athletes prior to exercise.
Methods: Two databases and 13 search terms were used to find relevant articles.
Results: To date, several position papers, observational, and experimental (25 investigations total) studies that included a pre-exercise fluid recommendation and protocols to achieve euhydration were identified.
Conclusions: Many of the fluid recommendations and protocols identified are different and some are not supported with evidence. In addition, very few have utilized fluid recommendations based on body weight. Future research could further investigate the use of fluid protocols catered to body weight or based on other practical assessment methods, in an effort to make individualized hydration plans.
A szabadidő-felhasználás és az önkéntesség kapcsolatának vizsgálata a magyarországi fiatalok körében

A nemzetközi szakirodalom a szabadidőeltöltés és az önkéntesség összekapcsolása során leginkább elméleti és definíciós problémákat tár fel, de nem vizsgálja a fiatalok szabadidőeltöltési típusainak összefüggéseit az önkéntesség esélyével. Alapvetésünk, hogy az önkéntesség és a szabadidő az életmód összekapcsolódó szeletei, még ha ennek irányáról a kutatói vélemények el is térnek. A tanulmány célja, hogy megvizsgálja, milyen tényezők alakítják a fiatalok önkéntességét, és ebben a rendszerben a szabadidőeltöltésnek mi a szerepe. Tanulmányunkban az önkéntesség esélyére ható tényezőket tárjuk fel a magyarországi fiatalok körében, különös tekintettel a szabadidőeltöltési formák hatására. Empirikus elemzésünk alapja a Magyar Ifjúság Kutatás 2020, mely a 15-29 éves korcsoportot reprezentálja egy 2000 fős valószínűségi mintán. Elsőként feltáró faktorelemzéssel szabadidőeltöltési típusokat határoltunk körül, majd az önkéntesség esélyét magyarázó regressziós modellünkbe a szakirodalomban előforduló standard magyarázó tényezők mellé beemeltük a kapott szabadidős faktorokat. A "kulturális mindenevők" elméletével összhangban eredményeink szerint két "mindenevő" faktor azonosítható, amelynek hangsúlyai vagy a magaskultúrára, vagy a rekreációra helyeződnek, ám végletesen nem választják el a két dimenziót. Regressziós modellünk szerint nagyobb az önkéntesség esélye, ha a fiatal rendelkezik saját megtakarítással, ha az apa alap- vagy középfokú végzettségű, ha nő, illetve akkor, ha a "szórakozásorientált mindenevő" faktor magasabb értéket kap. Ez azt mutatja, hogy az önkéntesség és a szabadidőeltöltés nem egyértelműen komplementer jelenségek, illetve annak oka, hogy az önkéntesség esélyét éppen a rekreációs faktor növeli, az lehet, hogy napjaink fiataljainak önkéntes tevékenységét és a szórakozásorientált szabadidőeltöltést is elsősorban a társas-közösségi jelleg motiválja és jellemzi. Elemzésünk tanulsága, hogy a fiatal kohorszot megcélzó, önkéntességet elősegítő programok megtervezésekor a közösségi és rekreációs elemek kiemelkedően fontosak lehetnek.
Önkéntesek szigete – a fesztivál önkéntesek motivációs vizsgálatának eredményei

Published: March 2023

A hazai legnagyobb könnyűzenei fesztivál, a Sziget Fesztivál, húszéves fennállása óta sikeresen követi a nemzetközi trendeket, nem csak kulturálisan, hanem az önkéntesek foglalkoztatása terén is. A rendezvény lebonyolítása során egyre nagyobb szerepe van a fesztivál önkénteseknek, ez mind az önkéntesek növekvő számában, mind pedig az önkéntesek feladatait szervező Fesztivál Önkéntes Központ munkájában tetten érhető. A fesztiválönkéntesség egy sajátos esete az epizodikus önkéntességnek. Tanulmányunk a Sziget Fesztivál fiatal önkéntesei példáján mutatja be azokat a motivációs tényezőket, ahol eltérés van az epizodikus önkéntesség különböző formái között ezen fajtája és az önkéntesség egyéb formái között. Kutatásunkat 2022 nyarán végeztük a Sziget Fesztivál önkéntesei körében kérdőíves módszerrel, az érvényes válaszok száma 311 volt. A korábbi, nemzetközi epizodikus önkéntesek körében végzett motivációs vizsgálatok eredményeivel egybehangzóan a Sziget Fesztivál önkéntesei számára is vezető motivációs tényező az elismertség és a társas interakció voltak. Ezt a motivációs bázist javaslatunk szerint a munkaszervezéskor érdemes szem előtt tartani az ellentételezésként nyújtott fesztiválbelépőn felül is. Kutatásunk fontos eredménye, hogy az epizodikus önkéntesség gyakorisága szerint megfigyelhető volt némi eltérés a motivációk sorrendjében és erősségében aszerint, hogy első alkalommal vagy visszatérő epizodikus önkéntesről van-e szó. A 25 év feletti fesztivál önkéntesek, akik más szervezeteknél rendszeresen végeztek önkéntes munkát jóval nagyobb hangsúlyt fektettek az önkéntes munka önbecsülésben betöltött szerepére, mint a kevésbé gyakori önkéntesek.

Comparative evaluation of impact strength of natural tooth and two different fragment reattachment technique
Authors: Dedgaonkar Amruta K. , Patel Alok R. , Jajoo Shweta S. , Shah Rohan , Shah Preetam , Choudhary Shweta
Published: March 2023

Background: The reattached fragments are prone to re-fracture if another traumatic episode occurs or under non-physiological use of the restored teeth. There is a scarcity of literature regarding the management of uncomplicated crown fracture reattachment following a further fracture Therefore, concerns have been directed towards the strength of reattachment of the fractured teeth. Hence the aim of the in-vitro study was to evaluate & compare the impact strength of reattached fragments with composite resin & polyethylene fiber impregnated in composite resin with that of the natural tooth. Methodology: Total samples of 42 teeth were collected and indicated for extraction. They were cleaned ultrasonically and later stored in a 0.9% saline solution. The samples were divided into three groups of 14 samples each. The fracture was induced by disk, only Ellis class II fractured teeth were included in the study. Group 1 (control group) sound tooth: Directly checked for impact strength. Group 2: Reattachment of the fractured fragment using composite resin. Group 3: Reattachment using polyethylene fiber impregnated in composite resin with minimal preparation. All samples were thermocycled between 5°C - 55°C for 500 cycles with 30 seconds dwell time and tested in an ‘impact testing machine’.
Biskup Vrhovac i Zagrebački kaptol za trajanja vizitacije Katedralnog arhiđakonata 1792. – 1794. godine u svjetlu rasprava Reflexiones de reformatione cleri Zagrabiensism i Vindiciae cleri Zagrabiensis
Authors: Ledić Stipe
Published: March 2023

U Zagrebu je u rujnu 1792. godine objavljena anonimna rasprava Reflexiones de reformatione cleri Zagrabiensis, a početkom 1793. Josip Keresturi odgovorio je također anonimno raspravom Vindiciae cleri Zagrabiensis.1 Obje su rasprave nastale u kontekstu Vrhovčeve vizitacije Katedralnog arhiđakonata od 1792. do 1794. godine. Cilj ovoga rada je detaljnom analizom latinskog teksta predstaviti oba djela kao narativne povijesne izvore u kojima se iščitava i otkriva problematika Zagrebačke biskupije te mentalitet i namjere naručitelja spisa. Pažljivim iščitavanjem dolazi se do zaključka da je Reflexione de reformatione cleri Zagrabiensis odražavao reformsku politiku biskupa Vrhovca i da nije bio koncipiran samo kao difamacija Zagrebačkog kaptola. Također, djelo pisca Josipa Keresturija Vindiciae cleri Zagrabiensis ne iscrpljuje se samo na »obrani« Kaptola nego svojim slojevitim diskursom ostavlja svjedočanstvo intenzivnog reformskog zamaha biskupa Vrhovca, ali i tadašnje problematike Zagrebačke biskupije i mentaliteta protagonista sukoba.
Uloga apostolskog delegata Pierrea Bastiena oko ne/uvođenja kongrue za katolički kler u Bosni i Hercegovini (1911. – 1914.)
Authors: Krešić Milenko
Published: March 2023

Autor u radu obrađuje ulogu apostolskog delegata Pierrea Bastiena oko uvođenja, odnosno neuvođenja kongrue za katolički kler u Bosni i Hercegovini. Congrua (prikladno uzdržavanje svećenika) bio je jedan od »kamena spoticanja« u odnosima između nadbiskupa Stadlera i dijecezanskog klera s jedne strane i franjevaca i biskupa iz njihova reda s druge strane. Kako se pitanje nije moglo riješiti međusobnim dogovorom, Sveta Stolica je rješenje tog pitanja pridržala sebi. Ulogu istražitelja povjerila je apostolskom delegatu Pierreu Bastienu, koji se pitanjem kongrue bavio od 1911. do 1914. godine. U radu su obrađena Bastienova izvješća i prijedlozi, prijedlog austrougarskih vlasti i Bastienove objekcije, odluka Svete Stolice o tom pitanju i reakcije klera na tu odluku.

A Review of Multimodel User Interface in Human Computer Interface Design
Authors: A. Chu Ying , Wu Chu Michael
Published: March 2023

The evolution of computers has inspired the conception of Human-Computer Interaction (HCI). Experiments in HCI are increasingly including members of the next generation (those in their twenties and thirties) who are well educated and proficient in modern technologies. In this paper, behavioral and technological issues are both addressed in the field of HCI. The primary goal of this research in HCI is to shed light on previously unseen perspectives of human behavior and its connection to technology. The concept of resilience has been used in several contexts, including the corporate world, psychology, education, and the economics. Self-efficacy, optimism, self-awareness, and the ability to derive meaning from one's experiences are just a few of the foundational factors that contribute to resilience. An improved organization's resilience may be achieved via the use of this method. All of this will be done by resilience in order to increase people's awareness of the tools at their disposal for dealing with the difficulties that already exist.
A Review of Art and Real World Applications of Intelligent Perception Systems
Authors: Ergenc Ceren , LI Yifei
Published: March 2023

Sensory data and AI/ML techniques are crucial to several robotics applications, which is why perception in robots is a hot topic. Some of these applications include: object recognition, scene understanding, environment representation, activity identification, semantic location classification, object modeling, and pedestrian/human detection. Robotic perception, as used in this article, is the collection of machine learning (ML) techniques and methods that allow robots to process sensory data and form conclusions and perform actions accordingly. It is clear that recent development in the field of ML, mostly deep learning methodologies, have led to improvements in robotic perception systems, which in turn make it possible to realize applications and activities that were previously unimaginable. These recent advancements in complex robotic tasks, human-robot interaction, decision-making, and intelligent thought are in part due to the fast development and widespread usage of ML algorithms. This article provides a survey of real-world and state of the art applications of intelligent perception systems in robots.
UMA DEVOÇÃO PERUANA NA ITÁLIA CENTRAL ENTRE PIEDADE POPULAR E CATOLICISMO OFICIAL
Authors: Cruzzolin Riccardo
Published: March 2023

No presente artigo são abordados dois temas entre eles entrelaçados. Em primeiro lugar é produzida uma reflexão sobre o modo em que a Igreja católica, como instituição, concebeu historicamente a diversidade cultural se detendo, em particular, no conceito de inculturação e em como deve ser conduzida a missão evangelizadora. Em segundo lugar, demos espaço à devoção popular expressada pelas populações não europeias, tomada aqui como resposta de baixo, senão como forma de resistência, às atividades de predicação e de apostolado desenvolvidas pelas figuras eclesiásticas. O êxito desses embates é uma rica dialética em que, por um lado, a Igreja tenta de incorporar e assim legitimar as expressões devocionais das classes mais humildes, por outro lado, os fieis se esforçam para defender uma religiosidade mais próxima de sua própria sensibilidade.
