Virtual property in the metaverse as an object of civil rights
Authors: Buletsa S.
Published: November 2022

The scientific article substantiates the need to include virtual property as an incorporeal object in the list of objects of civil rights. A comprehensive analysis of the development of the metauniverse, markets for the purchase of virtual property, the peculiarities of the legal regulation of legal issues in the Metauniverse in foreign countries, and the prospects for improving national legal regulation in this area was made. The author of the article analyzed the advantages of virtual property compared to real property and proposed to use smart contracts that use blockchain technology to settle legal issues in the Metaverse. The author of the article notes that currently there are no clear rules at the legislative level regarding the legal attributes and mechanism of virtual property transactions. Especially with the emergence of a new type of business such as Metaverse, the validation and use of relevant virtual properties will raise more complex legal issues that require further study. For Metaverse operators, in the process of creating virtual business scenarios, they should focus on providing a complete protection system for users' virtual property.

In addition, there is a problem with the value of property, because in the metauniverse it is not constant. It is mainly determined by the consensus of the group or both parties to the transaction. This method of determining value is similar to determining the value of collectibles and works of art in today's real society. However, it would be foolish to treat everything in the Metaverse as collectibles and works of art. In terms of impacting the real-world economic order, it may also do more harm than good. Thus, even if the problem of ownership of the metauniverse and the medium of exchange can be largely resolved, the problem of realizing the ownership of the metauniverse will still arise. The author analyzed a number of problematic aspects on the way to the development of quality legislation for the regulation of virtual property in Ukraine and provided some recommendations for their further consideration when developing legislation in this area.
Concept and legal nature of methods of protecting family rights and interests
Authors: Gavrik R.
Published: November 2022

In the scientific article, the author conducted a scientific study of doctrinal sources devoted to the issue of the concept of methods of protection of family rights and interests, determining on this basis the legal nature of methods of protection of family rights and interests. In the family legal doctrine has developed several approaches to the concept of "methods of protection of family rights and interests", which are mainly related to the application of other categories to the content of this concept - "form of protection of family rights and interests", "means of protection of family rights and interests", "about "objects of protection of family rights and interests", "grounds for the protection of family rights and interests" or the complete or partial separation of these concepts from the concept of methods of protection. Based on the conducted research, the author came to the conclusion that the methods of protection of family rights and interests are coercive measures defined by family legislation or a family contract, with the help of which influence is exerted on the participants of family relations, which are applied by bodies or persons specially authorized by the law to apply them or by the participants of family relations themselves in relation to themselves or other participants, and are aimed at the restoration of violated, unrecognized or contested family law, taking into account the family interest of the participant in family relations. The concepts of "methods of protection of family rights and interests" and "measures of protection of family rights and interests" are essentially identical. The application of a specific method of protection of family rights and interests is carried out with the help of means of protection of family rights, which is a relevant act of law enforcement, which is aimed at applying the relevant method of protection. The concepts of "method of protection" and "form of protection" are not identical, the latter is a procedural aspect of solving the question of the possibility and expediency of applying the appropriate method of protection.

The legal nature of the method of protection of family law or interest is that it: 1) the possibility of its application by the relevant jurisdictional subject or participant in family relations must be provided for by family legislation or a family contract; 2) represents a set of actions, which must be committed in accordance with the adopted law enforcement act or which are actually committed by a person in self-defense; 3) affects a violated, unrecognized or disputed family right or an unaccounted-for family interest, restores or takes into account a family right or a family interest; 4) the object of protection is any family right or interest, which are violated, not recognized, disputed or not taken into account; 5) may be applied in the interests of another participant in family relations if this is allowed by family law.
Theoretical approaches to certification of wills by the consul
Authors: Fursa Ye.
Published: November 2022

The article is devoted to the theoretical analysis of the procedure for certification of wills by a notary and a consul. It was emphasized that the certification of wills by notary differs from consul, since they carry out their activities in foreign countries and can apply not only the norms of Ukrainian legislation, but also international treaties and the legislation of foreign countries. The author proposed such a type of will as a "will with a foreign element", the certification procedure of which has its own peculiarities. A foreigner can apply to the Ukrainian consul to certify a will, but the consul can certify it only if it is related to entities living in Ukraine or concerns property located on the territory of Ukraine.Ensuring the secrecy of the will at consuls is due to the fact that it will be under several degrees of protection: notarial secrecy, as well as the inviolability of diplomatic and consular premises from state authorities. Therefore, taking into account these degrees of protection, it is advisable to certify wills at the consuls. But when a will is certified by a foreign notary, it will enter the system of registration of wills of that country, and a will certified by a Ukrainian consul - into the legal system of Ukraine, unless otherwise determined by the testator himself.The vision regarding the procedure for registration of wills by the consul in accordance with the Basel Convention on the introduction of the system of registration of wills is expressed, and theoretical approaches to solving some practical situations regarding the registration and archival storage of wills certified by the consul are proposed. Reasoned author's opinion about the possibility of a consul to certify a secret will of a spouse. Emphasis is placed on theoretical approaches to the type of notarial proceedings and some features of the stages of the notarization of the will by the consul and the consul’s consultative activity with the applicant regarding the choice of the best way to protect his property, rights and interests in the event of death by providing him with a memorandum of the will developed by the consul and its material nature , the certification and registration procedure with drafts of the will for preliminary review and processing by the applicant.

HAPPINESS AND MEANING IN IMPRISONMENT: THE IMPORTANCE OF SUFFERING IN THE EXPERIENCES OF NICOLAE STEINHARDT AND VIKTOR FRANKL
Authors: STADOLEANU Carmen
Published: November 2022

The paper describes the experiences of Nicolae Steinhardt and Viktor Frankl, both imprisoned despite their innocence, and their discovery of happiness and meaning through suffering and pain. Nicolae Steinhardt was a Romanian political prisoner of the communist regime and Viktor Frankl was a Jew imprisoned in the Auschwitz concentration camp. While in prison, Nicolae Steinhardt is secretly baptized and his life takes a very interesting turn. The discovery of God gives him access to the phenomenon of happiness and as he confesses, in prison he will live the happiest days of his life. Despite the miserable conditions, the pain, and the physical and mental torment, Steinhardt characterizes his happiness as ecstatic, passionate and life-changing. Under similar conditions, Viktor Frankl discovers the importance of suffering in determining the meaning of life. For Frankl, life always holds a potential meaning and if there is a meaning in life at all, then there must be a meaning in suffering. Therefore, through suffering and sorrow, and not in spite of them, Steinhardt and Frankl gain access to happiness and meaning.
Analysis of the Different Influences of Chinese and Western Religions on Law
Authors: Li-Yuan Wang
Published: November 2022

Man has to face the unknown future anytime and anywhere. For this reason, he needs to believe in the truth beyond himself. Otherwise, society will decline, decay, and never come back. Similarly, human beings are always faced with social conflicts everywhere. For this reason, he needs a legal system. Otherwise, society will disintegrate and fall apart. However, from the constitutional text, there is no uniform title and standard definition of freedom of religious belief in all countries. Countries in the west are called religious freedom, while China adopts the concept of freedom of religious belief. This article will further analyze the different influences of Chinese and western religions on the law. It is worth pointing out that the living environment of law in the west is not as good as Chinese people think, and the authority of law and people's belief in law are gradually drifting away. Based on the basic theory of freedom of religious belief, this paper analyzes the different influences of Chinese and western religions on the law, analyzes the present situation and demands for legal protection of freedom of religious belief in contemporary China, and tries to put forward feasible solutions.

Published: November 2022

As águas subterrâneas são um recurso valioso para suprir as necessidades humanas, servindo de múltiplos usos como abastecimento, irrigação, estâncias hidrominerais termais e engarrafamento de água mineral. Todavia o risco de poluição de aquíferos, relacionada à ausência de monitoramento do ambiente, obriga à busca de novas informações e tecnologias para mitigar os efeitos contaminantes. O estudo objetivou mapear a vulnerabilidade à contaminação de aquíferos sob a Unidade de Negócio Oeste SABESP (MO), por meio do método do Índice de Susceptibilidade (IS) que se baseia em cinco variáveis físicas. Foram usados como amostras 230 poços tubulares cadastrados no Sistema de Informações de Águas Subterrâneas (SIAGAS). Como resultado, a MO apresentou um IS variando de risco extremamente baixo a risco moderado-alto, com um risco médio de 45 pontos, classificado como baixo e que as áreas mais vulneráveis à contaminação estão localizadas em perímetro urbano. Conclui-se que a espacialização do IS é eficiente na identificação de áreas que estão mais suscetíveis às cargas poluentes, além de auxiliar no planejamento ambiental.

Making public works work: A framework for initiating right public infrastructure investments
Authors: Alnsour Moawiah A.
Published: November 2022

Public works (PWs) in Jordan seek to deliver public services that contribute to socio-economic growth and service provision. A clear framework for initiating PWs investments is lacking in Jordan to meet the required level of development of the country. This work sought to develop a framework for delivering the right PWs investments. The study found that there are several steps that need to be followed to deliver a desired project’s objectives. The study employed a qualitative method using semi-structured interviews. Besides the interviews, the document analysis approach was used and an extensive literature review was conducted. Experts in Jordan regarding PWs development were selected to participate in this study of developing a framework for the initiation of PWs investments. The study found that the framework should involve different steps and measures. They are integrated together to create a framework reflecting international practices in the context of Jordan.
'I was like a one-man band': the theory and practice of national development experts' work at the messy-middle
Authors: Covey Jack
Published: November 2022

Despite their importance to project outcomes, the work of individuals who occupy the meso-level of international development projects at the interfaces between an ever-growing number of actor groups is often poorly reflected on. Using four typically disparate bodies of literature (brokers and translators, street level bureaucracy, policy entrepreneurs, and institutional bricolage), I analyze how the work of national development experts (NDEs) at the meso-level influences how project intentions become social realities that reshape local lives. Normative and personal-professional motivations underpin NDEs' work at the messy-middle, encouraging them to work in a 'bottom-up' manner and to formally and informally create room for maneuver for all actors involved, drawing on relational skills and negotiating and utilizing multiple aspects of their individual identities. NDEs also work through conscious institutional bricolage, which they try to manage formally through contracts and informally through relationship-building, to integrate the project with the social environments in which it is being implemented. The analysis helps address key questions in existing meso-level actor literatures. It also shows that understanding meso-level work can facilitate improved understandings of how development projects move from intentions to social effects, which is a key concern for political ecology. I conclude by proposing that critical reflection could be a suitable methodology for assessing meso-level practice as it allows meso-level work to be discussed and learnt from without fully removing the spaces of informality and discretion that are vital to its success.

Continuous dependence for double diffusive convection in a Brinkman model with variable viscosity
Authors: Meften Ghazi Abed , Ali Ali Hasan
Published: November 2022

This current work is presented to deal with the model of double diffusive convection in porous material with variable viscosity, such that the equations for convective fluid motion in a Brinkman type are analysed when the viscosity varies with temperature quadratically. Hence, we carefully find a priori bounds when the coe cients depend only on the geometry of the problem, initial data, and boundary data, where this shows the continuous dependence of the solution on changes in the viscosity. A convergence result is also showen when the variable viscosity is allowed to tend to a constant viscosity.
A typology of adolescent online gamers. Part I
Authors: Pawłowska Beata , Potembska Emilia
Published: November 2022

Introduction: For several years now, there has been an increased interest on the part of psychiatrists, pediatricians, psychologists, specialists in education, and sociologists in the issue of so-called behavioral addictions, which include Internet addiction and computer gaming addiction. The aim of this study was to draw a typology of Internet gamers.

Material and methods: The examined group and method: The study involved 576 individuals aged 16 to 19 years. The participants were surveyed using an Inquiry Form and the Online Gaming Addiction Questionnaire designed by the present authors.

Results: The participants of this study were divided into four types of online gamers: gamers who scored the highest on the KBUGI scales and items corresponding to the DSM-5 criteria for Internet Gaming Disorder (Type 1); gamers who mostly played violent online games in which the player kills his enemies, destroys things, breaks traffic rules, and experiences power and new sensations (Type 2); individuals who played mainly to eliminate the feeling of boredom, enhance their mood and experience pleasure, new sensations and rivalry (Type 3); and people who only played occasionally and were not at risk of Internet gaming addiction (Type 4).

Conclusions: The four groups included gamers severely addicted to gaming; gamers who played violent games to satisfy their need for aggression (moderate Internet gaming addiction); gamers who played mainly to eliminate boredom and seek new stimuli (mild Internet gaming addiction); and non-addicted gamers.

Legal Status and Protection for Women Human Rights Defenders in Indonesia
Authors: Savitri Niken , Sitanggang Dyan Franciska Dumaris
Published: November 2022

The term "Human Rights Defenders" (Pembela HAM in Indonesia) refers to individuals or groups dedicated to defending and promoting human rights and fundamental freedoms. In their efforts, human rights defenders frequently encounter verbal threats, attacks, and even physical violence that significantly hinder their activities. Women human rights defenders play a crucial role in human rights activism; however, they are particularly vulnerable due to their gender. Their bodies, sexuality, and identities are often violently targeted, with gender stereotypes being exploited to justify these attacks. Despite this vulnerability, women human rights defenders in Indonesia lack adequate protection. This paper utilizes a normative analytical descriptive research method to explore the unique challenges faced by women human rights defenders as a vulnerable group and to examine the existing protective norms. The Indonesian government has an obligation, under current legal frameworks, to ensure the protection of women human rights defenders, taking into account their specific vulnerabilities.
Prisma Application as a Measuring Instrument of Corporate Obligations to Respect Human Rights
Authors: Rehulina Rehulina
Published: November 2022

The obligation of corporations to uphold human rights is a legal duty, as articulated in the UN Framework Protect, Respect, and Remedy on Business and Human Rights, which, while not a binding convention, is recognized as a source of customary international law due to widespread adherence among nations. This paper will focus on how states implement this resolution and ensure corporate compliance rather than discussing the UN resolution itself. In September 2014, Indonesia introduced the draft National Action Plan (NAP) for Business and Human Rights, which has yet to be legislated. However, the government has enacted policies to ensure that corporations respect human rights in their operations. In 2021, the Ministry of Law and Human Rights launched the PRISMA application (Business Risk Assessment and Human Rights) to help corporations assess potential human rights violations in their activities. This article aims to evaluate whether PRISMA can effectively measure the state’s duty to protect and corporate compliance with human rights from a due diligence perspective.
The Urgency of Whistleblowers legal Protection in the Criminal Justice System
Authors: Wahid Abdul
Published: November 2022

The role of whistleblowers is crucial in exposing criminal activities, as many cases remain undisclosed due to the absence of reports or whistleblowers coming forward. Whistleblowers are legally protected from both civil and criminal prosecution. Although the Witness and Victim Protection Agency (LPSK) is tasked with protecting witnesses and victims, its current scope does not fully extend to whistleblowers. Existing protections for whistleblowers primarily focus on reducing punishment if they are implicated in the case or witness the perpetrator's actions. Legal protection is unique and contingent upon the whistleblower providing testimony in good faith. To address this gap, revisions to the Criminal Procedure Code and the Law on the Protection of Witnesses and Victims are necessary to ensure that whistleblowers, even if involved in the crime, receive protection from criminal charges when they expose wrongdoing.

Takotsubo cardiomyopathy is a reversible cardiomyopathy with a unique morphological feature of the left ventricle characterized by an apical ballooning appearance known for approximately known 25 years. Catecholamine drive plays an essential role in the pathogenesis and pathophysiology of Takotsubo cardiomyopathy; hence, it is also called stress cardiomyopathy. Physical stress could also have an impact and leads to a greater variety of characteristics in Takotsubo cardiomyopathy.

Supportive and symptomatic medication remains the mainstay therapy with priority to improving the function of the left ventricle for several days and full recovery in 3-4 weeks. Due to its similarity with myocardial infarction, Takotsubo cardiomyopathy requires careful diagnosis and management for the best possible outcome.

The problem of lower limb preservation with symptoms of critical ischemia, resulting in necrosis of the distal foot portion, remains open. These cases require solving few tactical questions, such as the primary revascularization method, limb-preserving amputation, stimulation of regeneration, and finally, determining the criteria for auto-dermal transplantation.

We analyzed 29 patient cases with critical lower limb ischemia of fourth grade, according to the Fontaine classification (or the sixth category according to Rutherford�s classification), who underwent partial foot amputation due to dry gangrene and were threated using PRGF�-ENDORET� platelet-rich plasma and platelet-rich fibrin technology. The control group was comprised of 21 patients who received traditional postoperative wound treatment. All patients went through a combination of transluminal revascularization and platelet-rich plasma to create a �therapeutic� neoangiogenic effect. Indications for these procedures were severe distal arterial occlusion and stenosis.

Using transluminal procedures with platelet-rich plasma therapy improves the blood perfusion to the distal portions of the limb in patients with critical ischemia in a short time, which is an informative diagnostic criterion for wound healing after amputation. Plasmatic membranes create an optimal environment for tissue regeneration, thus reducing the wound closure time using an auto-dermal transplant.

Endometriosis is a chronic benign hormone-dependent condition when the endometrial tissue, identical with the endometrium by its morphological and functional properties, grows outside the borders of the uterine mucous membrane. Recent studies have pointed to the possible role of matrix metalloproteinases (MMPs) in the pathogenesis of endometriosis. We suggested a hypothesis that increased expression of MMPs activity in eutopic and ectopic endometrium of patients with endometriosis might correlate with the presence of endometriotic lesions.

The aim of the study was to evaluate the level of MMP-2 and MMP-9 expression in the ectopic endometrium of women with visible endometriotic lesions and eutopic endometrium in patients with no signs of endometriosis.

The study was conducted on 43 patients. They were divided into two groups. Group 1 included 31 patients with peritoneal/ovarian endometriosis who had undergone laparoscopy and hysteroscopy. Group 2 consisted of 12 patients with leiomyoma, endometrial polyps or relatively healthy patients who had undergone hysterectomy or polypectomy and endometrial curettage.

This study showed statistically higher expression of MMP-2 (1.7783 ± 0.22 immunohistochemistry (IHC) optical density score compared to the control group – 1.41± 0.34, p = 0.0017) and MMP-9 (1.352 ± 0.067 versus 1.85 ± 0.26 in the control group, p = 0.001) in ectopic and eutopic endometrium samples from patients with endometriosis compared to samples taken from patients without endometriosis. A strong correlation between expression of the above-mentioned MMPs (r=0.74 for MMP-2 and r=0.88 for MMP-9) in ectopic and eutopic endometrium might be of promising diagnostic value.
