Opis:
The pandemic is not in favour of any scientific symposia and conferences, especially the international ones. Many have been cancelled, while some managed to migrate into the Internet. This was the case of the conference organised by the Progect Network for the Study of Progressive Rock, entitled ‘Progressive Rock and Metal: Towards a Contemporary Understanding’ and originally scheduled to take place in May 2020 in Ottawa, Canada. Due to pandemic restrictions, the event was first moved to 2021 to finally, a few months later, offer a fully remote and “virtual” formula; hence the name change to Virtual Progect.

Opis:
Multiple sclerosis (MS) is a demyelinating, inflammatory, autoimmune disease of the central nervous system which affects most commonly young adults. It has wide spectrum of clinical and radiological presentations with relapses or steady progression. Recent years have brought new reports on the pathogenesis of MS. This systematized the current MS classification and created new parameters describing the course of the disease, such as activity and progression. Attention has been paid to the need for new drugs that focus on the treatment of progressive MS. Until now, the primary and secondary progressive MS have been somewhat forgotten, and most of modifying-disease drugs have been registered in the treatment of relapsing-remitting subtype. In recent years, not only new drug has been registered for the treatment of progressive MS (ocrelizumab) and another one is planned to be approved soon (siponimod), but also indications of old medicines (interferon-beta1b, cladribine, mitoxantrone, cyclophosphamide, azathioprine) have been extended. Despite intensive development, there is still a great need to seek new drugs that will stop the progression of disability in MS patients.

Opis:
After a prolonged absence of the topic of education reformers in the public discussion nowadays it’s obviously an increased interest in their approaches and models of performance. The theoretical reflections of the progressive education based on the ideas of the creative power of the child figuring in a mythical, romantic-coded image of the child as a genius. This conception was in opposite to the rigid forms of teaching, to every automatism of learning, against the authoritarian treating of teachers with students.

Prison penalty, progressive penitentiary system
Opis:
The article is concentrated on the procedure of carrying out the prison penalty in 1918–1938. You can distinguish two periods important for Polish penitentiary law in these times. The first of them was marked by taking out prisons from the occupants’ hands and by building grounds of Polish penitentiary system. The important step on this field was done on March 7th, 1928, when the President’s decree on system of prison organization was passed. This decree opens new period in Polish penitentiary system, because the progressive system of carrying out the prison penalty was introduced to Polish law then. The model was in accordance with the European standards and was taking into account the resolutions of penitentiary congresses of this time. However, the reality of prisons However, the reality of prisons was significantly different. The progressive system was introduced only with small group The progressive system was introduced only with small group of sentenced persons. More than 70% of prisoners had no work and they were kept in crowded prisons with no sufficient hygienic conditions. The problem of crowded prisons was only partially solved by the amnesty acts.

Opis:
The current article is an attempt by the authors to present a bioethical case, or rather a search being undertaken to develop tools to interpret the novel ontological realm which has been created, and continues to be transformed in real time, by the COVID19 pandemic and its aftermath. The ontological realm is new, but the physical features of the world and the human in it are partially constants and identical to the previous realm parameters, the pre-COVID19 space-time. The question of existence in the new ontological realm is...how can the continuum of Homo sapiens and its existence be sustained in this new realm? The tools being developed use of previous information and knowledge of the members of Homo sapiens as a starting point and source of metaphors as tools to facilitate existence in the new realm. In this way, existing knowledge, which is held by individual members of Homo sapiens, and which exists and continues being created in the continuum of Homo sapiens, can be the foundation for the creation of new knowledge about the post-COVID19 realm and the individual and collective comprehension of humans of it and in it. Conceptual metaphors, the creation of compound metaphor and the prospective dialectic are suggested by authors as a possible epistemic implementation mechanisms in this context. The adaptation of humanity, its imagination and some professions are used to demonstrate the case for the ‘new science of human existence’ in the post-COVID19 world.

Opis:
The paper looks at personal income tax (PIT) in Poland from the perspective of its progressiveness, redistribution effect and influence on prosperity. Household budget surveys carried out by the Central Statistical Office (GUS) in 2003-2005 are the main source of data. The statistical and econometric analysis included in the paper takes into account some basic measures of tax progression. The author also uses a decomposition approach to determine PIT’s effect on the average tax rate in the country. The empirical study conducted by Aksman shows that even though Poland’s PIT is progressive, its overall redistribution effect is not very strong; in the analyzed period it reduced household income inequalities by only 5.22% on average. This is mainly due to a low effective tax rate, Aksman says. What’s more, PIT leads to a decline in prosperity measured with the Sen index; in the analyzed period of time prosperity declined by 11.23% annually on average. With PIT, “poverty aversion” is stronger than “inequality aversion,” the author says, which means that the loss of prosperity resulting from the fall in average income is greater than the increase of prosperity resulting from reduced income disparities.

Opis:
Horizontal crash at road and rail vehicles generates human and material injuries, many of them with important negative effects. Damper in bumper a known solution for vehicles protection at crash is realized with different damping devices, from passive elements to actuators. Usually the devices are tunedfor 5 km/h crash speed. After collision the passive solutions destroy and must be removed with other new devices. The solutions using standard shock absorbers and actuators are improper the first dissipating insufficient energy and actuators being more expensive and having a long reaction time so the damping coefficient changing is realized in too low steps. VZN damper concept granted with European Patent EP l 190 184 and Romanian Patent RO l 18546, characterized by progressive damping coefficients with the stroke is a great opportunity to realize simple and cheap protection at crash, due to its capacity to realize constant damping force without mechanisms and electronics. li is necessary only to tune accordingly VZN damping characteristic to this desiderate. VZN concept consist of u piston rod attached to a piston without valves moving inside inner cylinder close at both ends and filled at rebound and compression by specific fllling valves placed in upper /bottom lids or on the ends of the inner cylinder. The damping effect is realized by valves or in cheap solution by metering orifices (holes/slots) placed sideways inner cylinder in convenient position. Due to this structure VZN tuning for constant damping force at different piston speed can be realize both with identical metering holes/slots placed at optimal distances, or placing metering holes/slots of different areas at eąual distances. The numbers of metering holes/slots are enough such the steps speed evolution be practical continuous and thus the damping force be practical constant. The VZN behaviour is increased by new components e.g. levelling pistons, double guiding elements and balancing solutions. Paper presents the theory used to dimension VZN damper placing metering orifices at eąual distances, a practical device with levelling piston and simulation comparative to standard one. The standard damper dissipates 30-40% lower energy comparative to VZN one. This means in the same situation in which VZN damper reduces constant speed from 30, respectively 20 [km/h] to zero, the standard dampers reduces speed up to 14, respectively 11 [km/h], then collapsing the vehicle.

Opis:
Traditional masculinity has been thoroughly explored in psychological research, but its counterpart, progressive masculinity, has undergone relatively little scientific investigation. To determine whether this lack of attention to or understanding of progressive masculinity is mirrored more largely in mainstream culture, we examined how men and women conceptualize and experience gender roles in their everyday lives. Participants were randomly assigned to describe a time in which they had behaved either traditionally or progressively with regard to their gender. Over 80% of men and women in the traditional condition and women in the progressive condition provided condition-appropriate examples. However, men in the progressive condition only provided progressive examples 17% of the time, suggesting that many men may not have an understanding of progressive masculinity. Additional themes, implications, and directions for research on progressive masculinity are discussed.

The paper presents the implementation of methods for progressive mesh encoding. The described implementation is a modification of the software published in 2008 by Zhao He, which is based on studies by Michael Garland and Hugues Hoppe. We focused on improving the performance of the software. In particular we modified the data structures to ensure their better indexing, which significantly improved the computational complexity of the algorithm. We also implemented the support for simplified meshes with textures. The authors present the comparison of the performance of these methods in relation to the original He Zhao's algorithm. The performance of progressive mesh encoding in our implementation was significantly improved.
W artykule przedstawiono implementację algorytmu kodowania siatek trójwymiarowych do postaci progresywnej. Opisana implementacja jest rozwinięciem oprogramowania opublikowanego w 2008 roku przez He Zhao, które bazuje na opracowaniach Michaela Garlanda [1] oraz Huguesa Hoppe [5]. Celem autorów było wykorzystanie prezentowanego oprogramowania do kodowania siatek o znacznym rozmiarze, reprezentujących między innymi skany eksponatów muzealnych lub modele uzyskane w wyniku obrazowania medycznego. Wobu przypadkach kodowanie do postaci progresywnej ma na celu zapewnienie efektywnego przesyłania i szybkiej prezentacji siatek na różnych poziomach wizualizacji szczegółów (levels of detals). Jednocześnie powinno ono umożliwiać szybkie odzyskanie oryginalnej siatki w razie potrzeby wykonania pomiarów. Skupiono się na poprawie szybkości działania algorytmu poprzez wprowadzenie struktur danych zapewniających ich odpowiednie indeksowanie, co znacząco poprawiło złożoność obliczeniową. W porównaniu do możliwości oferowanych przez oprogramowanie He Zhao została także dodana uproszczona obsługa progresywnego kodowania siatek z teksturami. Przeprowadzono i przedstawiono w artykule porównanie czasów działania oprogramowania w prezentowanej wersji oraz w implementacji He Zhao i wykazano, że wydajność czasowa uległa znaczącej poprawie.

The non-linear structural analysis is considered as a basic design procedure, which is used for checking of the structural robustness in accidental design situation. It is explained by following reason: a non-linear structural analysis based on realistic constitutive relations for basic variables (average values) makes possible a simulation of a real structural behavior. It should be pointed that, implementation of the non-linear structural analysis in design of concrete structures requires an alternate approach to safety verification. The paper presents a new approach to safety format for non-linear analysis of RC structures subjected to accidental loads.

Nowadays, when schools are closing and teachers are made redundant, a question arises whether the current educational system and the teaching methods or the knowledge and skills which people leave school with are adequate. Now, as never before, students and em-ployers realize how important practical skills are in the labor market. Where are schools and universities in meeting this need? Do schools answer the natural needs people have for self--development? Does the educational system stimulate development of individuals interests? Unfortunately, I think the answer to a lot of these questions would be negative. Yet, if so, it is time we fi nd a way to offer something more, not only to young people, but also to adults who want to explore the area of their interests by taking the trouble to obtain further degrees. One of the solutions to the urgent needs for the educational system is a pragmatic approach towards learning and teaching.

Opis:
The paper is founded on the distinction between traditional school represented by Johann F. Herbart and progressive school here represented by Bell Hooks. The main purpose of this article is to describe specific characteristics of these two educational models taking into account changes within them. Foucault’s disciplinary power schema provides methodological tools for better apprehension of the location of power in the classroom. In particular, the concept of exam mentioned by Foucault in his Discipline and Punish: The Birth of the Prison has great importance for better understanding of changes within the two aforementioned educational models and student-teacher relations. It appears that power is a fundamental element in these relations, which is exemplified by the presence of the hidden curriculum and how it affects students. Conceiving teaching as a technical activity the autor argues that the way this power is performed depends on the teacher’s character, skills and will.

Opis:
Objectives: The aim of the study was the epidemiological analysis and evaluation of selected clinical and sociodemographic factors in Polish patients with primary progressive multiple sclerosis. Methods: The study included patients from 7 provinces in central and eastern Poland registered in the Registry of Patients with Multiple Sclerosis on 31 December 2016. The incidence of various forms of the disease was compared, and clinical, demographic and social disparities between relapsing-remitting and primary progressive multiple sclerosis were analysed. Results: Of 3,199 registered patients, 2,188 persons (66.2%) had the relapsing-remitting form of multiple sclerosis, 774 (24.2%) had the secondary progressive type and 307 (9.6%) suffered from primary progressive disease. The first symptoms of primary progressive multiple sclerosis appeared almost 10 years later than in patients with the relapsing-remitting type (39.2 ± 11.4 vs. 29.8 ± 9.8). The period from the first symptoms to diagnosis was more than twice as long in patients with primary progressive multiple sclerosis (5.8 ± 3.4) as in those with relapsing-remitting disease (2.4 ± 1.6). The average degree of disability in the Expanded Disability Status Scale was similar and amounted to 3.2 ± 2.1 for relapsing-remitting and 3.6 ± 2.4 for primary progressive multiple sclerosis. The relapsing-remitting form was observed more often in women (2.4:1), and the primary progressive form appeared with equal frequency in both sexes (1:1). Disease-modifying treatment was received by 34% of patients with relapsing-remitting and in only 1.9% of patients with primary progressive multiple sclerosis. Conclusions: The primary progressive form affects approximately 10% of Polish patients with multiple sclerosis. The first symptoms appear at about 40 years of age with equal frequency in both sexes, and its diagnosis takes more than twice as much time as in the case of relapsing-remitting multiple sclerosis.
Cel: Celem badania była analiza epidemiologiczna oraz ocena wybranych czynników klinicznych i socjodemograficznych polskich pacjentów z pierwotnie postępującym stwardnieniem rozsianym. Metody: Do badania włączono pacjentów zamieszkujących 7 województw środkowej i wschodniej Polski, objętych Rejestrem Chorych ze Stwardnieniem Rozsianym w dniu 31 grudnia 2016 roku. Porównywano częstość występowania poszczególnych postaci choroby, a także analizowano różnice kliniczne, demograficzne i społeczne między postacią rzutowo-remisyjną i pierwotnie postępującą stwardnienia rozsianego. Wyniki: Spośród 3199 zarejestrowanych pacjentów postać rzutowo-remisyjną miało 2188 osób (66,2%), wtórnie postępującą – 774 (24,2%), a pierwotnie postępującą – 307 (9,6%). Pierwsze objawy postaci pierwotnie postępującej stwardnienia rozsianego pojawiały się prawie 10 lat później niż w przypadku postaci rzutowo-remisyjnej (39,2 ± 11,4 vs 29,8 ± 9,8). U chorych z postacią pierwotnie postępującą okres od pierwszych objawów do rozpoznania był ponad dwukrotnie dłuższy (5,8 ± 3,4) niż u tych z postacią rzutowo-remisyjną (2,4 ± 1,6). Średni stopień niesprawności w Rozszerzonej Skali Niewydolności Ruchowej (Expanded Disability Status Scale, EDSS) był zbliżony i wynosił 3,2 ± 2,1 dla postaci rzutowo- -remisyjnej i 3,6 ± 2,4 dla pierwotnie postępującej. Postać rzutowo-remisyjną częściej stwierdzano u kobiet (2,4:1), natomiast postać pierwotnie postępująca występowała z równą częstością u obu płci (1:1). Leczenie modyfikujące przebieg choroby otrzymywało 34% osób z postacią rzutowo-remisyjną i tylko 1,9% z pierwotnie postępującą. Wnioski: Postać pierwotnie postępująca występuje u około 10% polskich pacjentów ze stwardnieniem rozsianym, pierwsze objawy pojawiają się około 40. roku życia z jednakową częstością u obu płci, a diagnoza postaci pierwotnie postępującej zajmuje ponad dwukrotnie więcej czasu niż rozpoznanie postaci rzutowo-remisyjnej.

Opis:
In recent times, German as a language with a well-functioning tense system is developing a special progressive form, marking actions and processes which are continual and not yet terminated. There is a variety of forms like beim Arbeiten or gerade im Begriff sein zu arbeiten, but most usual and by far most grammaticalised is the am-progressive (er ist am Arbeiten, “he is working”). In this paper the restrictions which still exist are discussed. They are limited, but although they are not entirely accepted in standard German, the range of these constructions is extensive. In spite of this fact, the German language does not tend to develop general aspectual markers. A comparison with English shows this clearly. However, in its early periods the German language had overt aspectual characteristics. Especially constructions with the present participle and the auxiliary verbs sein and warden could function as aspect partners. These constructions gradually disappeared at the end of Middle High German. Thus, modern German has only very few aspectual markers, which are restricted to progressive constructions verbalizing actions and processes in actual situations.

Opis:
This paper presents a fully scalable image coding scheme based on the set partitioning in hierarchical trees (SPIHT) algorithm. The proposed algorithm, called fully scalable SPIHT (FS-SPIHT), adds the spatial scalability feature to the SPIHT algorithm. It provides this new functionality without sacrificing other important features of the original SPIHT bitstream such as: compression efficiency, full embeddedness and rate scalability. The flexible output bitstream of the FS-SPIHT encoder which consists of a set of embedded parts related to different resolutions and quality levels can be easily adapted (reordered) to given bandwidth and resolution requirements by a simple parser without decoding the bitstream. FS-SPIHT is a very good candidate for image communication over heterogenous networks which requires high degree of scalability from image coding systems.

Opis:
The progressive collapse of a space grid structure which has a large number of members and a large span is the focus of current research. Before the progressive collapse of the structure, there is a problem of instability of the members. In this paper, dynamic nonlinear analysis of a super-long span latticed steel arch structure is carried out to study its progressive collapse process using a Kinematic Hardening Plasticity constitutive model compiled by Vumat material subprogram in Abaqus, which takes into account instability of the members. Differences in the dynamic response process of the structure at the collapse moment and the failure sequence of the members using the member stability model and the material failure constitutive model are compared. Compared with the material failure constitutive model, when the member stability constitutive model is used, the proportion of compressive buckling members in the structural failure is higher, and the bearing capacity of the structure is lower when the initial failure occurs. The structure suffers from localized member compressive failure rather than material yielding, which leads to the progressive collapse of the structure.

Opis:
The gear which is the central safety element of the friction drive lift during braking is exposed to overloading connected with changeable weight which loads the lift braking system. In the article the results of numerical analysis for braking process of CHP 2000 type progressive gear distinguished by an innovative design have been presented. The numerical analysis was conducted with the use of a simulation of the gear roller displacement depending on changeable loading with the support of Abaqus/CAE software. Displacement of the gear roller from the neutral position in which the gear starts loosing energy of speeding up weight to zero was simulated. The results obtained from computer simulations were verified on the basis of a physical experiment at the bench station created to verify braking parameters of the gears with the use of free fall method.

Opis:
Passive security at crash is an importami problem both for road, and aerial vehicles, first case at horizontal collision and second at vertical one, on landing operation on ground or deck. Both generate human and material injuries, many of them with important negative effects. Damper in bumper a known solution for vehicles protection at crash is realized with different damping devices, from passive elements to actuators. Usually the devices are tuned for 5 km/h crash speed and after collision the passive solutions destroy and must be replaced with other new devices. The solutions using standard shock absorbers and actuators are improper the first dissipating insufficient energy and actuators being more expensive and having a long reaction time so the damping coefficient changing is realized in too low steps. VZN damper concept granted with European Patent EP l 190 184 and Romanian Patent RO l 18546, characterized by progressive damping coefficients with the stroke assures protection at crash, due to its capacity to realize constant damping force without mechanisms and electronics, tuning damping characteristic to this desiderate. The paper presents the differences between the energy must to be dissipated at the same crash speed in horizontal and vertical situation, it being increased at vertical situation, due to the gravity. The same paper evaluates the advantages confers by VZN damper concept comparative to standard one, for both vertical and horizontal collision and concludes the VZN one is better 39% at vertical crash and 25% at horizontal crash comparative to standard one, due to its efficient dissipating system.

Opis:
On landing operation, a brutal contact with the dech or ground, can damage the plane or chopper and hurt the pilot, the crew or the passengers. The paper presents the advantages confer by suspensions using VZN dampers, in this situation. The Romanian self adjustable damper (shock-absorber) concept- VZN-granted with European Patent EU 1190184 and Romanian Patent 118546 assures damping coefficients increasingly by stroke from lower value up to the very high values, giving thus possibility to dissipate a huge energy at all speed regimes high, medium or low. With a convenient damping valve placement and/or dimension, the VZN concept confers possibilities to assure constant decelerationforces, at the human body limit resistance, this solution dissipating the maximal energy ąuantity. The paper indicates solutions for VZN tuning in order to be used to realize constant deceleration at crash and developed one of them for a practical device realizes. The samples where developed so to be realized with components used in actual automotive shock absorber manufacturing, so prototypes being easy to realize. Despite the simulations was realized considering standard damper dissipating energy function piston speed, not sąuare piston speed, the standard damper dissipated 48.5% lower energy comparative to VZN one. This means in the same situation in which VZN damper reduces constant speed from 20 [km/h] to zero, the standard dampers reduces speed up to 11.5[km/h], then collapsing the aerial vehicle.
