Artykuł odnosi się do kwestii odpowiedzialności karnej za zachowania związane z dawstwem zarodka, które mogą mieć miejsce w ramach realizacji umów o macierzyństwo zastępcze. W tym celu przeanalizowano przede wszystkim znamiona czynów zabronionych stypizowanych w przepisach ustawy z 25 czerwca 2015 r. o leczeniu niepłodności (tekst jedn.: Dz.U. z 2017 r., poz. 865) – to jest: zbywania lub nabywania zarodka w celu uzyskania korzyści majątkowej lub osobistej, rozpowszechniania ogłoszeń o odpłatnym zbyciu lub nabyciu zarodka oraz postępowania z zarodkami w sposób niezgodny z przepisami powyżej ustawy. Tekst zawiera ponadto odniesienia do wyjaśnienia zjawiska macierzyństwa zastępczego oraz jego statusu w prawie polskim.
This article is on criminal liability under Polish law for behaviour related to the donation of embryos that may take place as part of surrogate arrangements. I analyse the features of prohibited acts specified in the provisions of Ustawa z 25 czerwca 2015 r. o leczeniu niepłodności (the Treatment of Infertility Act of 25th June 2015, Dziennik Ustaw 2017, Item 865, uniform text) i.e. embryo disposal or acquisition to derive material or personal benefit, dissemination of advertisements for embryo provision or receipt in return for payment, and embryo handling in breach of the legal provisions. I also refer to descriptions of surrogate maternity and its status in Polish law.

Opis:
Building my argument on the analysis of two cases of anti-Roma violence (Oświęcim 1981 and Mława 1991), I would like to search for a pattern of evolution of anti-gypsyism in Poland. In the 1980s, the ambiguous stereotype of Roma, has been giving way to the picture of Roma as a convenient scapegoat to be blamed for the insecurity and economic hardships. This shift in the stereotypical image of Roma, together with the specific “management of discontent” performed by the communist authorities, prompted pogrom-like outbreaks of anti-Roma violence in the towns of Konin and Oświęcim. Similar attacks on Roma have taken place again in the beginning of the next decade, already in post-communist Poland. The mob aggression against Roma in the town of Mława in 1991, although retained many features of the earlier acts of violence, has already represented a new pattern in which Roma personified the fears associated with the transformation toward neoliberal capitalist economy. This new pattern of perception has provided fertile ground for the racialization of the anti-Roma discourse which I intend to trace down in the most contemporary instances of hate speech against Roma.

Opis:
Contemporary medicine offers more and more possibilities as far as procreation is concerned. They are available, first of all, to infertile couples (IVF – In Vitro Fertilization). However, the advanced reproductive technology is also used by people who are biologically capable of having children. These people are ready to resign voluntarily from pregnancy and childbirth difficulties. The surrogate motherhood appears as a phenomenon known already from biblical times but existing nowadays in a different context. At the same time, some issues are emerging – questions concerning social, ethical, moral and legal consequences. This paper presents the issue of surrogate motherhood in the context of social changes, which could lead to a development of such practices as well as the reasons of parents and surrogate mothers. Can this phenomenon be perceived as a service for people who want to fulfill their desires for having children? Would surrogate motherhood become a socially approved practice? What are the ethical, religious and legal norms concerning this phenomenon? The religious norms are connected, first of all, with an attitude of the Catholic Church which recognizes surrogacy as unacceptable and states that “it offends the dignity and the right of a child to be conceived, carried in the womb, delivered to the world and brought up by their own parents”. The ethical norms refer to the biotechnological issues and include matters of creating and implanting human embryos as well as the problem of the surrogate mother – child – biological parents relationship. As far as legal norms are concerned, the case is still open hence Polish law does not take into consideration in vitro fertilization or the admissibility of surrogate motherhood.

The history of surrogacy is composed of cases of happy solving family problems, but also of conflicts and lawsuits concerning a child and his welfare. In modern times it became the next to adoptions additional possibility of ensuring infertile individuals fulfillment of their dreams of posterity. It can also be used for comfort of a woman - to avoid the burdens of pregnancy and delivery, or for a comfort of a man – to be a single father without a mother of a child, wife and family ties with her. Since its beginning in late 70-ties of XX century, legality and ethical aspects of surrogacy are lively discussed, as well in the court rooms, as in the doctrine. The following article is an attempt to deal with just some of the mentioned ethical problems.

The lack of a legal framework did not prevent Ukraine from ranking third among the world leaders in the use of cryptocurrencies in 2022. In terms of the sum of indicators, Ukraine is ahead of such tech giants as the United States (5th place), China (10th place), and the United Kingdom (17th place). The purpose of the study is to identify the underlying principles for the introduction of a new legal definition of “digital things” and “digital content” and their prospects for use, which are laid down in draft laws No. 6447 and No. 6576, as initiatives that are satellites to the relevant law on virtual assets. As a reminder, the Parliament of Ukraine adopted the Law of Ukraine “On Virtual Assets” No. 2074-IX on February 17, 2022. Since the adoption of Law 2074 by the Parliament of Ukraine on February 17, 2022 and until the period of 2023, significant events have taken place. They have significantly affected the plans of the Parliament of Ukraine to launch mandatory amendments to the Tax Code of Ukraine provided for in the Draft Law 7150 and simultaneously enact Law 2074 from October 1, 2022. The study was based on the analysis of the legislative framework of Ukraine, the European Union and other international acts, including those ratified by the Parliament of Ukraine. The study has led to a number of conclusions. Draft Law No. 6447 introduces the definition of a “digital thing” that is in circulation only in digital form; these include virtual assets, digital content, online accounts, money and securities that exist exclusively in digital form. Its adoption will help potential consumers to protect their rights to digital content, online accounts, virtual assets, even money and securities that exist exclusively in digital form. Comparing the concepts of “digital thing” and “digital content” proposed by draft laws No. 6447 and No. 6576, we found signs of legal tautology in determining what is primary and what is secondary. The addition of the words “digital content” to Article 177 of the Civil Code and the expansion of the concept of a thing to “material and digital things” is at least more declarative.

One of the most areas of research in recent years, is decision making methodologies under conflicting multi-objective. Due to this, several techniques have been developed. Among them, Surrogate Worth Trade - Off (SWT) method is interested to solve the multi-objective problem by analysts and researchers. This paper intends to review and application of Surrogate Worth Trade - Off technique. The SWT method is one approach that provides an interference between the decision maker’s preferences and the mathematical models associated with the non-dominated solutions. In the final part of this work a method is proposed in order to use SWT technique with multiple decision - makers.

Term “jet fuel” is well known and recognized worldwide - it applies to aviation product used to power all turbine engines in aircrafts and helicopters. Its’ properties are clearly and strictly defined in international specifications. However, in the discussion concerning jet fuels, and in most research material, many people seem to forget that this fuel is a mixture of different hydrocarbons, is produced from different feedstock (crude oil from different sources available worldwide) and as a final product is obtained with different production processes. Thus, however jet fuel must meet the requirements defined in international standards, these fuels differ each other and as a result, differences can be observed in logistic chain and in combustion process. This paper points out some differences between jet fuels and its aim is to convict users, researchers and all people in aviation industry dealing with jet engines operation, that - when talking about jet fuel - many factors and details about final product must be considered, and this type of product should not be seen as single-type fuel, as most people see it now. The article has been prepared within the research project funded by the National Science Centre in Poland and granted with decision no. DEC-2011/01/D/ST8/06567.

Opis:
Background: The aim of this review is to present the available clinical and surrogate endpoints that may be used in future studies performed in patients with peripheral artery occlusive disease (PAOD). Importantly, we describe statistical limitations of the most commonly used endpoints and offer some guidance with respect to study design for a given sample size. The proposed endpoints may be used in studies using surgical or interventional revascularization and/or drug treatments. Methods: Considering recently published study endpoints and designs, the usefulness of these endpoints for reimbursement is evaluated. Based on these potential study endpoints and patient sample size estimates with different non-inferiority or tests for difference hypotheses, a rating relative to their corresponding reimbursement values is attempted. Results: As regards the benefit for the patients and for the payers, walking distance and the ankle brachial index (ABI) are the most feasible endpoints in a relatively small study samples given that other non-vascular impact factors can be controlled. Angiographic endpoints such as minimal lumen diameter (MLD) do not seem useful from a reimbursement standpoint despite their intuitiveness. Other surrogate endpoints, such as transcutaneous oxygen tension measurements, have yet to be established as useful endpoints in reasonably sized studies with patients with critical limb ischemia (CLI). Conclusions: From a reimbursement standpoint, WD and ABI are effective endpoints for a moderate study sample size given that non-vascular confounding factors can be controlled.

Opis:
The intention of this paper is to clarify how state patrons control non-state proxy forces fighting on their behalf. In order to address the subject matter thoroughly, specific attention was paid to a number of questions including a) the criteria determining patronproxy relations, b) factors influencing the selection process of proxy forces, and c) principles governing the maximisation of potential benefits of using proxies, whilst simultaneously reducing risks and associated costs. The author applied a neo-realistic research paradigm to his work. Patron-proxy relations were presented in the context of the principal-agent theory, as well as through detailed analysis of ongoing scenarios involving Iran and Hezbollah, Russia and the Donbass separatists, Pakistan and Kashmiri militias, the US and Syrian rebels. The essence of war by proxy is to influence the strategic result of an armed conflict without direct, full-scale, military intervention. The use of non-state proxy, external actors is aimed at maximising their political goals and strategic interests whilst maintaining “plausible deniability”. By supporting non-state proxies, indirectly or by providing limited direct assistance, sponsors operate below the threshold of war. Empirical analysis of proxy war cases proves that such models may both guarantee “strategic victory” or become a “double-edged sword”. One of the key challenges for external powers engaged in war by proxy is to avoid unintended consequences (blowback). The author argues that elements such as ideology, ethnicity or religion do not necessarily ensure control over proxies, whilst the range of common goals and interests, and the level of the proxy’s dependency, are crucial.

Opis:
In many cases, a X̅ control chart based on a performance variable is used in industrial fields. Typically, the control chart monitors the measurements of a performance variable itself. However, if the performance variable is too costly or impossible to measure, and a less expensive surrogate variable is available, the process may be more efficiently controlled using surrogate variables. In this paper, we present a model for the economic statistical design of a VSI (Variable Sampling Interval) X̅ control chart using a surrogate variable that is linearly correlated with the performance variable. We derive the total average profit model from an economic viewpoint and apply the model to a Very High Temperature Reactor (VHTR) nuclear fuel measurement system and derive the optimal result using genetic algorithms. Compared with the control chart based on a performance variable, the proposed model gives a larger expected net income per unit of time in the long-run if the correlation between the performance variable and the surrogate variable is relatively high. The proposed model was confined to the sample mean control chart under the assumption that a single assignable cause occurs according to the Poisson process. However, the model may also be extended to other types of control charts using a single or multiple assignable cause assumptions such as VSS (Variable Sample Size) X̅ control chart, EWMA, CUSUM charts and so on.

Opis:
Because of their prolific nature on the battlefield, rocket propelled and gun-launched grenades are of particular concern to the soldier, particularly because of the severe reaction that occurs when a munition is hit by the shaped charge jet. As a result of the danger that such a detonation poses, it is necessary to more precisely understand the behaviour of munitions subjected to these types of devices. In response to these threats, standardized 81 mm and 40 mm shaped charge warheads were developed for use during threat assessment testing to act as a consistent, lower-cost representative of shaped charge projectiles commonly encountered on the battlefield, and to help quantify the interaction of these jest with explosive charges. The international standards for shaped charge jet threat testing uses the Held initiation criteria V²D, where V is the jet velocity and D is the diameter. V²D was computationally predicted using the high-rate continuum models CALE and ALE-3D. The surrogate warheads were test fired through aluminium target plates to strip off jet mass to adjust the V²D to the threat munition.

What is the definition of family? why is the conventional nuclear family being replaced by new types of households? and what are the potential consequences of redefinition of family for society as a whole? These are some of the most important questions. Family ethics and bioethics could be an excellent framework to present the historical and social background of these kinds of phenomena.

Opis:
In the present study a novel method is introduced to detect meaningful regions of a gray-level noisy images of binary structures. The method consists in generating surrogate data for an analyzed image. A surrogate image has the same (or almost the same) power spectrum and histogram of gray-level values as the original one but is random otherwise. Then minmax paths are generated in the original image, each characterized by its length, minmax intensity and the intensity of the starting point. If the probability of the existence of a path with the same characteristics but within surrogate images is lower than some user-specified threshold, it is concluded that the path in the original image passes through a meaningful object. The performance of the method is tested on images corrupted by noise with varying intensity.

Opis:
This work examines the reduced-cost design optimization of dual- and multi-band antennas. The primary challenge is independent yet simultaneous control of the antenna responses at two or more frequency bands. In order to handle this task, a feature-based optimization approach is adopted where the design objectives are formulated on the basis of the coordinates of so-called characteristic points (or response features) of the antenna response. Due to only slightly nonlinear dependence of the feature points on antenna geometry parameters, optimization can be attained at a low computational cost. Our approach is demonstrated using two antenna structures with the optimum designs obtained in just a few dozen of EM simulations of the respective structure.

Opis:
In the framework of good laboratory praxis the emphasis is placed on the quality of reproducible results. Methods of mathematic statistics are very useful for this reason. In the form of regulating diagrams they can help to quick identification of that results which are outside the required tolerances. There are a lot of various samples used for statistical regulation. One possibility how to control the efficiency of whole analytic process, from preparing to the final determination, is using of surrogate standard. 2,4,5,6-tetrachloro-m-xylene and decachlorobiphenyl were used as surrogate standards for the determination of PCB in various types of water. These compounds were examined during relatively complicate determination of PCB in beer. The concentration was determined by Shewhart’s diagrams for individual values and sliding span according to standard ČSN ISO 8258. This example of PCB determination in beer indicates the possibility of using surrogate standards as a powerful tool for determination of quality results.
W ramach dobrej praktyki laboratoryjnej kładzie się nacisk na jakość uzyskanych wyników. Do ich oceny wykorzystuje się matematyczne metody statystyczne. Za pomocą schematycznych diagramów można szybko zidentyfikować wyniki pozostające poza wymaganymi granicami tolerancji. Istnieje wiele różnych metod statystycznych używanych do tych celów. Jedną z możliwości kontroli efektywności całego procesu analitycznego, od przygotowania próbki do końcowego oznaczenia, jest użycie standardów zastępczych. Do oznaczania PCB w różnych rodzajach wody użyto 2,4,5,6-tetrachloro-m-ksylenu i dekachlorobifenylu jako wzorców zastępczych. Związki te zostały zbadane podczas stosunkowo skomplikowanego oznaczania PCB w piwie. Stężenie zostało określone za pomocą schematów Shewharta dla poszczególnych wartości, zgodnie z normą ČSN ISO 8258. Ten przykład oznaczania PCB w piwie wskazuje na możliwość korzystania ze standardów zastępczych jako istotnego narzędzia do określenia jakości wyników.

Opis:
This paper is the theoretical analysis of the method for determining viscous friction characteristics in an industrial robot joint. For the purpose of calculating the value of viscous friction, the surrogate mass of driven robot arms and their common surrogate center of gravity was used. In order to ensure the value of surrogate mass to be correct, the analysis of friction hysteresis influence on a motor's driven torque was performed. The analysis of dynamic phenomenon of friction was performed by numerical robot joint and robot arms models.
Identyfikacja parametrów dynamicznych robota przemysłowego wymaga stosowania złożonych procedur pomiarowych oraz obliczeniowych. Proces identyfikacji w ogólnej postaci sprowadza się do opracowania modelu matematycznego, który opisuje badany obiekt w sposób ogólny a następie wyznaczane są wartości parametrów tego modelu. W tym celu swoje zastosowanie znajdują różne techniki estymacji, które pozwalają na wyznaczenie parametrów modelu w taki sposób, aby wyniki działania modelu jak najbardziej zgadzały się z wynikami rzeczywistych pomiarów. Powszechnie stosowaną metodą estymacji jest Metoda Najmniejszych Kwadratów. Podczas stosowania tej techniki dynamiczny model robota reorganizowany jest do postaci liniowej. Wówczas wszystkie identyfikowane parametry zestawiane są w jednej macierzy. Umożliwia to zastosowanie algorytmu jednocześnie estymującego wartości wszystkich parametrów. Jest to często proces złożony i czasochłonny ze względu na dużą liczbę pomiarów oraz dużą liczbę parametrów branych pod uwagę. Utrudnia to także badanie dynamicznych zjawisk tarcia w przegubach robota. Autorzy pracy proponują podejście upraszczające proces identyfikacji parametrów dynamicznych robota przez zastosowanie zastępczej masy unoszonych ramion. Wprowadzenie masy zastępczej pozwoli na wyznaczenie charakterystyki tarcia w sposób niezależny od grawitacji i kierunku ruchu a także na obniżenie liczby jednocześnie identyfikowanych parametrów dynamicznych. W celu określenia technicznych możliwości wdrożenia proponowanego podejścia, autorzy przeprowadzili analizę teoretyczną wpływu histerezy tarcia statycznego w przegubie robota na jakość pomiarów. Analizę teoretyczną poparto symulacjami komputerowymi. Podejście to pozwoli także na uniknięcie konieczności stosowania wiedzy a priori.

Opis:
In this work, a genetic-algorithm-based Kriging model with multi-point addition sequence optimization strategy is addressed to make up for the shortcomings of Kriging model with single point criterion. This approach combines the multi-point addition strategy with genetic algorithm to enable the Kriging model to efficiently capture the globally optimal solution. Based on this, a multi-level surrogate method is presented by employing a local surrogate model to modify the Kriging global surrogate model, and then applied to design optimization to improve the accuracy and efficiency of global optimization. Meanwhile, a reliability design optimization method based on multi-level surrogate model is studied by dealing with the reliability constraints with an adaptive reliability penalty function. Numerical examples show that the proposed method can find the optimal solution of the object problem with the least calculation cost under the condition of satisfying the reliability constraint.

Opis:
Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various substrates is presented. The proposed approach is based on inverse surrogate modeling with the scaling model constructed for several reference designs that are optimized for selected values of the substrate permittivity. The surrogate is set up at the level of coarse-discretization EM simulation model of the antenna and, subsequently, corrected to provide prediction at the high-fidelity EM model level. The dimensions of the antenna scaled to any substrate permittivity within the region of validity of the surrogate are obtained instantly, without any additional EM simulation necessary. The proposed approach is demonstrated using an ultra-wideband monopole with the permittivity scaling range from 2.2 to 4.5. Numerical validation is supported by physical measurements of the fabricated prototypes of the re-designed antennas.

Artificial procreation and reproductive genetics have become a reality in which, thanks to the tools of contemporary medicine, all sorts of interference into human organism are possible. Man has become to create himself. In this context, it is vital to take into account positive law regulations because of the variety of standpoints and differences in defining the core of natural law. Undoubtedly, religious aspect has to be part of bioethical discussions, because for many people religion is a source of moral behaviour. However, we have to remember that public and private sphere of ethics are two different aspects which should not be mingled in a democratic state. Bioethical discussions have resulted in international regulations, for example bans on reproductive cloning of humans, eugenic practices aiming at selecting people, therapies resulting in changes within the human genome, commercialization of a human body, etc. Polish legislators are facing a difficult problem to determine a detailed legal framework of artificial procreation and reproductive genetics to meet not only the European standards of the Bioethical Convention, but also cultural determinants and expectations of the society.

Opis:
This paper uses a Genetic Algorithm (GA) to reduce total tardiness in an identical parallel machine scheduling problem. The proposed GA is a crossover-free (vegetative reproduction) GA but used for four types of mutations (Two Genes Exchange mutation, Number of Jobs mutation, Flip Ends mutation, and Flip Middle mutation) to make the required balance between the exploration and exploitation functions of the crossover and mutation operators. The results showed that use of these strategies positively affects the accuracy and robustness of the proposed GA in minimizing the total tardiness. The results of the proposed GA are compared to the mathematical model in terms of the time required to tackle the proposed problem. The findings illustrate the ability of the propounded GA to acquire the results in a short time compared to the mathematical model. On the other hand, increasing the number of machines degraded the performance of the proposed GA.
