Unsupervised Machine Learning for Improved Delaunay Triangulation

Physical oceanography models rely heavily on grid discretization. It is known that unstructured grids perform well in dealing with boundary fitting problems in complex nearshore regions. However, it is time-consuming to find a set of unstructured grids in specific ocean areas, particularly in the case of land areas that are frequently changed by human construction. In this work, an attempt was made to use machine learning for the optimization of the unstructured triangular meshes formed with Delaunay triangulation in the global ocean field, so that the triangles in the triangular mesh were closer to equilateral triangles, the long, narrow triangles in the triangular mesh were reduced, and the mesh quality was improved. Specifically, we used Delaunay triangulation to generate the unstructured grid, and then developed a K-means clustering-based algorithm to optimize the unstructured grid. With the proposed method, unstructured meshes were generated and optimized for global oceans, small sea areas, and the South China Sea estuary to carry out data experiments. The results suggested that the proportion of triangles with a triangle shape factor greater than 0.7 amounted to 77.80%, 79.78%, and 79.78%, respectively, in the unstructured mesh. Meanwhile, the proportion of long, narrow triangles in the unstructured mesh was decreased to 8.99%, 3.46%, and 4.12%, respectively.

Assessment of human impact on flooding for Thai East coast - gulf basin

Due to a rapid increase in urban and built-up areas, the East Coast – Gulf basin of Thailand faces flood hazards more frequently than in the past. In this study, we aim to assess the effects of building construction on flooding, and any link between them. The FloodMap model is used to simulate flooding in the study area in September 2015. Two flooding scenarios were designed; one based only on land surface elevation and the other one with building construction included on the land surface. According to the result, we found that human construction increases flood hazard in the study areas, particularly flood depth. Flood areas are also found to increase if the human factor is added into the model, but in a lesser extent. With human construction, paved road is found to have the highest flood potential compared to other types of road. Built up areas are more flooded, while flooding extent is almost similar to results from the scenario of no human construction in forest and agricultural areas.

Identity of personality and specificity of its self-presentation in virtual communicative space

The purpose of the article is to reveal the features of constructing a personal identity in a virtual environment. Methodology. The choice of research methods is determined by the purpose of the article and the subject of research, in particular, general scientific and empirical techniques are used, based on a systematic approach to the analysis of works on the problems of interpretation of virtual identity. The scientific novelty of the obtained research results lies in the correlation of the essence of the concepts "real identity" and "virtual identity", identifying the features and risks of the formation of the latter. The article highlights the factors of human construction of a "virtual" identity, which often occurs due to dissatisfaction of the individual with his real identity. It is emphasized that virtual reality provides ample opportunities for self-expression and disclosure of personal potential, but the desire to always "be online" affects the physical health of the user, thereby increasing his anxiety, leads to fatigue and irritability, exacerbation of hyperdynamic. The problem of excessive immersion in cyberspace has been identified: by abusing being in it, an unformed personality can lose life landmarks, assimilate programmed solutions and ready-made mental stamps. Conclusions. In social networks, a person can easily create an ideal image of himself, which is less authentic than the real one, because it reflects the individual's idea of an invented, ideal set of their own qualities, which are completed with ready visual, textual and audio network tools. Social "slowing down" in the Internet environment significantly reduces the moral level of communication in social networks and messengers. Even today, the level of trust among young people in semi-anonymous messages on the Internet is higher than in traditional sources of information. At the same time, the unsystematic acquisition of knowledge in this way does not allow young people to form an established picture of the world, leaving it largely fragmented.

Contemporary Vietnam Economy Present Situation and Development Trend

Human development is one of the most important goals of development. Under the impact of socio-economic conditions and the practical needs, the issue of human development is conceived more and more completely, comprehensively and deeply in the current period. The article analyzes and clarifies the basic issues related to human construction and development in Vietnam today.

Embodiment of Ancestral Spirits, the Social Interface, and Ritual Ceremonies: Construction of the Shamanic Landscape among the Daur in North China

The case study in this paper is on the Daur (as well as the Evenki, Buriat, and Bargu Mongols) in Hulun Buir, Northeast China. The aim of this research is to examine how shamanic rituals function as a conduit to actualize communications between the clan members and their shaman ancestors. Through examinations and observations of Daur and other Indigenous shamanic rituals in Northeast China, this paper argues that the human construction of the shamanic landscape brings humans, other-than-humans, and things together into social relations in shamanic ontologies. Inter-human metamorphosis is crucial to Indigenous self-conceptualization and identity. Through rituals, ancestor spirits are active actors involved in almost every aspect of modern human social life among these Indigenous peoples.

Kesehatan Jiwa Islam Telaah terhadap Pemikiran Abu Zaid al-Balkhi dalam Buku Maṣāliḥu al-Abdān wa al-Anfus

The discourse on mental health is often an interesting and beneficial discussion across time. There are many developing concepts adopted from western thoughts. The concept offered by Islamic Psychology has not been explored yet. One of them is the concept of mental health from the perspective of Abu Zaid al-Balkhi. This study aims to analyze the concept of Islamic mental health, specifically the thought of Abu Zaid al-Balkhi in the book Maṣāliḥu al-Abdān wa al-Anfus. By using a type of qualitative research with a descriptive-analytical method specifically in describing and analyzing mental health concepts, according to Abu Zaid al-Balkhi. Based on this research, it can be seen that mental health or a healthy soul is the stability of the soul’s strength in humans so that it can defeat the turmoil of psychiatric signs. Al-Balkhi classifies psychiatric symptoms into four groups, namely, sadness and anxiety (al-ḥuzn wal jazʻ), obsession (al-waswas), anger (al-gaḍab), and finally, fear and phobia (al-khauf wa al-fazʻ). To achieve happiness, humans should always try and strive for a balance between the body and soul. The attachment of both (body and soul) is in harmony with human construction, namely physical and spiritual. Caring for and maintaining health as a preventive effort is preferred than treating it if already sick. This is what distinguishes the concept of healing the soul of Islam, according to al-Balkhi, with the concept of western secular psychotherapy

Man in a network society

Today we are not talking about criticism of the traditional image of man, but about the end of faith in human exceptionalism. The human rights movement is recognized as a form of logo-centrism and is shifting towards the protection of the rights of women, children, the disabled, prisoners, migrants and other minorities. Voices are heard in defense of the rights of animals and non-human beings with artificial intelligence (a pair of robots have already obtained citizenship rights); scientists are discussing the possibility of reconstructing human beings based on gene technology. A profound transformation of perceptions about man is taking place in the models of the new network globalization, which replaces the liberal and conservative projects of the unity of mankind. The development of PR technology, which dealt a blow to the ideals of individual freedom and democracy in civil society, has turned man into a controlled being. The order of a global network society is no longer determined by human criteria of good and evil, but by information and financial flows. The digital revolution in work and entertainment, education and culture, as well as economics and politics has led to the creation of many digital counterparts, while man himself, deprived of the protection of the state and society, has found himself in a situation of anomie and total loneliness. Thus, transhumanism is no longer a mental experiment of marginal philosophy, but a post-human stage of civilization development. Discussions about the future of a network society, artificial intelligence and human construction based on gene technologies should not be perceived as intellectual entertainment, which free minds have been exposed to in recent years. They should not be neglected, because the more scenarios of possible development will be created and calculated, the better humanity will respond to the next crisis.

The problem of certainty of legal cognition (in the context of the evolution of Nature Law)**

The article deals with the problem of certainty of legal cognition in the context of the evolution of Natural Law. It is noted that the category of certainty was understood differently by representatives of various scientific schools and strands of theoretical framework idea. However, the classical doctrines were similar in the sense that certainty is necessary as the initial principle of cognition of legal reality, in contrast to the relativistic post-classical theories, which took the diametrically opposite principle as a methodological basis, namely «uncertainty». The article actualizes the understanding that Nature Law as a classical type of legal understanding has an internal logic of development. It is noted that modern theories of «Resurgence of Natural Law» generally remain within the framework of natural law concepts, but still overcome the dualism and parallelism of the systems of natural and positive law. In ontology, the modern Natural Law recognizes the human construction of law, the participation of the subject in the constant reproduction of legal reality; in epistemology, it recognizes the inclusion of the subject in the process of cognition, the rejection of the absolutization of the «legislative» mind and the transition to an interpretive «communicative» mind; in axiology, it defends socio – cultural concretization, including in the current legal system. The authors actualize the idea of intersubjectivity of law as integrating various aspects of legal cognition and the operation of law, focusing on identifying the meaning of law not from the point of view of one – dimensional monosubjectivity (individual or homogeneous society), but in dialogical (polylogical) intersubjectivity - in the interaction of subjects of legal communication. Recognition of the dynamism of law, the actualization of law in law enforcement activities problematizes the idea of certainty in law, but on a new, human-centered methodological and theoretical basis.

NATURAL HISTORY OF THE BLACK IGUANA Ctenosaura similis (SQUAMATA: IGUANIDAE) IN ISLA CONTOY, QUINTANA ROO, MEXICO

The genera Iguanaand Ctenosaurabelong to the Iguanidae family, and populations of most species of these genera have decreased due to anthropogenic effects. The natural history of most species of this family is poorly known, including Ctenosaura similis. Therefore, this study documents some ecological aspects of the species, such as its feeding habits, and habitat and microhabitat use in a population on Isla Contoy in Quintana Roo, Mexico. The data showed that even though C. similisis distributed throughout the island, individuals more commonly use human construction (buildings) of Parque Nacional Isla Contoy (PNIC) and mangrove areas. Microhabitats most used by all age classes and sexes were rocks and trees. The diet of the species is omnivorous; however, the frequency of prey type consumed changes with the age of the individuals (hatchlings, juveniles, and adults), as well as with the season of the year. The practice of cannibalism by some individuals is also reported, as well as coprophagy and scavenging. This work provides general information on the life history of C. similis, complementing the scarce information that is currently available.

How we speak and think about gender: Conceptual metaphors in the Serbian language

The influence of human experience on observations about different physical and non-physical entities has been ignored and even denied for a long time within the framework of Western philosophy, which has been occupied with the question of language, among other things. Mark Johnson and George Lakoff's cognitive approach to language, which developed in the 1980s, has shown that ways in which people interact with their environment have a strong effect on the ways of understanding concepts. Such understandings, if not entirely then in a fair degree, are realized by metaphors that therefore cease to be primary and only defined as a stylistic device. Taking into account that gender and/or its contextual background are often overlooked in many analyses of conceptual metaphors, this paper endeavours to examine the abstractness of the concepts woman and man through the research in The Corpus of Contemporary Serbian. If the human understanding of abstract concepts comes, at least partially, through metaphors, and woman and man as a subcategory of the concept human are abstract, then man and woman must also be represented through one of the possible forms of the metaphor - metaphorical linguistic expressions. At the same time, the social context in which we are talking and thinking about women and men is marked by contemporary patriarchy and heteronormativity, and this is by no means negligible in its closer definition. Woman and man do not exist, or it is unimportant if they exist beyond human construction and imaginative conceptualization. The fact that something is a construct does not mean that it is without real and dangerous consequences.
