AbstractPedestrian-induced footbridge vibration comfort level is a complex problem that has been studied for a long time. However, no consensus has been reached on a quantitative calculation index for assessing vibration comfort level. Only simple comfort limits, rather than specific relationships between comfort level and the vibration endurance capacity of pedestrians, are currently available for assessing vibration comfort level of footbridges. This article aims to propose a sensitivity model for pedestrian-induced vibration comfort calculation based on the vibration endurance capacity of pedestrians and the vibration response of footbridges. The concepts of “human body resistance” and “vibration effect” were established according to the principle of probability and statistics. Mathematical definition of sensitivity was put forward. Calculation expressions for a pedestrian and pedestrians were deduced respectively. A theory of pedestrian-induced footbridge vibration comfort level was proposed. Field survey and experiment were conducted, the results of the field survey demonstrated that sensitivity values were in good agreement with the international vibration comfort standards. Furthermore, the field experiment results showed that the errors between the experimental results and the calculated results were within 6%. The proposed sensitivity theory can be used for pedestrian-induced footbridge vibration comfort quantitative calculation.

Broad Meaning

The definition of person and non-person always change through legal history. Long time ago, law did not recognize the personality of slaves. Recently, it accepted non-human legal subject as legitimate person before the law. This article examines sufficient conditions for being person in the eye of law according to its particular purposes, and then, analyses the meaning of legal person in criminal law. In order to do that, scientific methodology that is adopted in this research is doctrinal legal research combined with philosophical approach. Some theories regarding person and legal person were analysed, and then the concept of person was associated with the accepted definition of legal person that is adopted in the latest Indonesian drafted criminal code. From the study that has been done, can be construed that person in criminal law concerned with norm adressat of the rule, as the author of the acts or omissions, and not merely the holder of rights. It has to be someone or something with the ability to think rationally and the ability to be responsible for the choices he/she made. Drafted penal code embraces human and corporation as its norm adressat. Corporation defined with broad meaning of collectives. Consequently, it will include not only entities with legal personality, but also associations without legal personality. Furthermore, it may also hold all kind of collective namely states, states bodies, political parties, state’s corporation, be criminally liable.

And Control

In this paper, Linear Quadratic (LQ) optimal control concepts are applied for the active control of vibrations in helicopters. The study is based on an identified dynamic model of the rotor. The vibration effect is captured by suitably augmenting the state vector of the rotor model. Then, Kalman filtering concepts can be used to obtain a real-time estimate of the vibration, which is then fed back to form a suitable compensation signal. This design rationale is derived here starting from a rigorous problem position in an optimal control context. Among other things, this calls for a suitable definition of the performance index, of nonstandard type. The application of these ideas to a test helicopter, by means of computer simulations, shows good performances both in terms of disturbance rejection effectiveness and control effort limitation. The performance of the obtained controller is compared with the one achievable by the so called Higher Harmonic Control (HHC) approach, well known within the helicopter community.

The article is devoted to the consideration of such an object of interdisciplinary research as the elite, namely, the latest trends in its study. It is shown that the consideration of this phenomenon has been going on for a long time, but now there is a sharp change in the focus of research – a new methodology is being developed. This is due to the fact that the axiom taken is the provision of a significant influence of the elite not only on the distribution of resources (economic, political, administrative) but also on the development (or recession) of the nation as a whole. The article presents a detailed analysis of the methodology for measuring the elite quality index which formed the basis for an international study conducted in 2020.

This review explores certain challenges related to the notion of customary international law. It seems that it was a long time ago when international law academics and practitioners ever thought that the nature of this source was a well-settled topic. Nowadays international lawmaking processes involve an extraordinary number of interactions, taking place both formally and informally. Such complex features are reflected by an exponential increase in the scholarly study of international legal sources. The legal nature, its applicability and principles regulating customary international law are addressed in the book under review (Brian D Lepard (ed), Reexamining Customary International Law (Cambridge University Press 2017)) through several topical essays. The chapters offer a comprehensive analysis of these lawmaking processes and the challenges they portray from various perspectives and in various fields, such as: What is customary international law and why is it law? Is it law because it reflects a ‘global legislative’ model? What is the current value of the persistent objector theory? Is the two-element definition of customary international law still applicable? By meticulously addressing these and other inquiries, the book presents novel arguments and represents a stimulating addition to the literature on sources of international law.

AbstractIn the people of South Kalimantan, there are sub-ethnic groups who are well-known as successful business people / entrepreneurs and can maintain their business in a relatively long time, namely Alabio. historically, Alabio have become traders/businessmen who are undoubtedly their trade characteristics. His success in commerce even began when there was a belief in "mysticism", namely since the days of the state of Daha and Dipa were founded. The results of research on business ethics values used by Alabio for social studies showed that the business ethics values of Alabio for social studies learning were not fully utilized by social studies teachers, to facilitate teachers in compiling learning resources based on the Competency Standards of Business Ethics / Economic Ethics, namely Business ethics values used by Alabio can be used in social studies material in class VII, namely on the material of economic ethics in utilizing the factors of production in the life of business, the definition of business, company and business entity, and considerations that need to be considered in doing business.Key Word:  Business Ethics, Alabio People, Social Studies Learning AbstractMasyarakat Kalimantan Selatan, ada kelompok sub-etnis yang dikenal sebagai pengusaha sukses dan dapat mempertahankan bisnis mereka dalam waktu yang relatif lama, yaitu Alabio. Secara historis, Alabio telah menjadi pedagang/pengusaha yang tidak diragukan lagi adalah karakteristik perdagangan mereka. Keberhasilannya dalam perdagangan bahkan dimulai ketika ada keyakinan dalam "mistisisme", yaitu sejak zaman negara bagian Daha dan Dipa didirikan. Hasil penelitian tentang nilai etika bisnis yang digunakan oleh Alabio untuk studi sosial menunjukkan bahwa nilai etika bisnis Alabio untuk pembelajaran IPS tidak sepenuhnya dimanfaatkan oleh guru IPS, untuk memfasilitasi guru dalam menyusun sumber belajar berdasarkan Standar Kompetensi Etika Bisnis. Etika Ekonomi, yaitu nilai etika bisnis yang digunakan oleh Alabio dapat digunakan dalam bahan studi sosial di kelas VII, yaitu pada materi etika ekonomi dalam memanfaatkan faktor-faktor produksi dalam kehidupan suatu perusahaan dan entitas bisnis, dan pertimbangan yang perlu dipertimbangkan dalam melakukan bisnis.Kata Kunci: Etika Bisnis, Masyarakat Alabio, Pembelajaran IPS

Increasing the inclusion of underrepresented individuals in coding is an intractable problem, with a variety of initiatives trying to improve the situation. Many of these initiatives involve STEAM education, which combines the arts with traditional STEM disciplines. Evidence is emerging that this approach is making headway on this complex problem. We present one such initiative, iLumiDance Coding, which attempts to pique the interest and increase confidence of students in coding, by combining it with a fun and physical activity: dance. The connections between dance and coding, while not immediately obvious, are authentic, and we hypothesize that this approach will increase student comfort level with coding. We used student surveys of attitudes toward coding and a variety of statistical approaches to analyze our initiative. Each analysis showed a positive effect on student comfort level with coding. These results are useful for both educators and researchers since they contribute to a deeper understanding of how to increase interest in coding, which we hope will lead to an increase in representation.

The article summarizes the definition of the term “hikikomori”, analyzes the situation of quarantine restriction: its essence and features of the impact on adolescence. Peculiarities of manifestation of hikikomori markers at adolescence are determined. We consider the studied phenomenon in the system of approaches like a way to meet needs, as a set of manifestations of syndromes of a new era, as a psychological defence mechanism, as a psychological state and process. Depending on the intensity of markers, we divide hikikomori into counter-dependent, poorly adaptable and interdependent, super dependent. The parameters that determine the level of manifestations of hikikomori include antisocial solitude at home, antisocially with leaving the house, selective society. The levels of manifestation of hikikomori include physical, emotional, social. Quarantine restrictions, as unusual living conditions that require forced solitude, selfisolation can be a factor that encourages the emergence of markers of hikikomori in adolescents. Such people have a shift in activity in cyberspace and at night, inseparable stay with the gadget (during meals, in the bathroom, in the toilet, etc.). Neglect of the organization of life (do not clean the bed after sleep, do not clean the room for a long time, do not change clothes during the day and wear night pyjamas around the clock, neglect a healthy diet, eat outside the regime, mostly fast food, etc.). In communication with others, they show irritability with the desire to avoid contact and solitude in their room. Also, at such a person, disorganization of educational activity hastily is observed. It is difficult for them to organize the learning process; they show procrastination (postponement of tasks). If the classes are as videoconferencing, they do not include video and microphone. They are away from contact with the group and the teacher, even if they need contact for feedback, they ignore it. An empirical study of the susceptibility to hikikomori markers in adolescents revealed that about 40% of subjects have a high susceptibility to hikikomori markers, and almost 11% of young men – very high.

Communication Culture

The article analyzed the peculiarities of the interpretation of the «communication culture» in the context of scientific researches of the past and contemporary domestic researchers. An analysis was carried out to define the concept of «communication culture of a person», the approaches to the definition of this concept are singled out. The positions of scientists concerning the role of eloquence in the formation of the linguistic personality are analyzed, the language is analyzed as a «social and psychological phenomenon», historical conditions of the formation of the concept of «communication culture» are characterized, in particular, attention is focused on the formation of the linguistic personality. It was found out that studies of the ancient traditions of the formation of the language of culture make it possible to better understand modern trends in the development of the person's communication culture. Modern studies have shown that in linguistics for a long time there was no unity in the interpretation of the concepts of «language» and «communication». Problems of the formation of the culture of broadcasting have become the object of research by eminent thinkers, beginning with the period of Antiquity. The question of the formation of a culture of speech has long traditions. Note that in European linguistics, the first decades of the twentieth century. Theoretical study and approval of the concept of «culture of language» in the scientific circulation is underway. It should be noted that in connection with the introduction of information and communication technologies in all spheres of society life has increased interest in the theory and practice of eloquence. This is explained by the fact that the active use of information and communication technologies involves the search for ways of speaking influence, both on the interpersonal and on the public level. According to authoritative experts in rhetoric, L. Matsko, O. Matsko, N. Mykhailychenko, V. Poltupets, etc., there are also communicative reasons that ensure the actual and further development of the theory and practice of oratory in the XX-beginning of the XXI century.

Architectural forming in the Moderne movement lies, or rather stems from the function, that is, from the structure bulk, whose composition dictates volumetry which is the principal characteristics of a structure. It can be stated that this simplified definition of architectural forming in the Nis Moderne is only partially true, because many other factors influenced forming and creation of the Nis Moderne. The very introduction states that until 30's of the last century, the prevailing styles and directions in Serbian Moderne, and by virtue of this, in Nis, were classicistic pseudo styles, national romantic architecture based on Serbian-Byzantine style, as well as folk architecture. Many authors leading the Moderne in Serbia and Nis, often designed at the beginning of their careers in some of the mentioned styles or combined them, so that the influence of these styles and directions was felt for a very long time in their designing opus. Often, the investors' wishes to add an element or two on the fa?ade in order to make it 'more beautiful and richer' left its mark - the majority of Moderne buildings in Serbia and Nis are a sort of compromise resulting from this struggle between old styles, investors' preferences and architects' aspirations to something new.

It is a complex problem to study the interaction between sand castle and flowing water, which needs to consider the complexity of seawater flow and the stress of sand castle structure. The authors use the fluid-solid coupling model to establish the connection between the fluid field and the structural mechanical field, and use the finite element analysis to complete the simulation modeling of the transient process of wave impact and sandcastle foundation deformation. This paper analyzes the stress and the first principal strain of the sand castle foundation in the direction of flow velocity when the sand castle foundation is hit by waves, as a method to judge the strength of the sand castle.The best shape: the boundary value of sand castle collapse caused by strain have been determined, so as to obtain the maximum stress that a sand castle foundation can bear before collapse, which makes it possible to use the fatigue strength calculation theory of sand castle solid to carry out the quantitative calculation of sand castle durability. At the same time, the impact of waves is abstracted as wave motion equation. Finally, the finite element analysis technology is adopted to calculate the main strain of sandcastles of different shapes under the impact of the same wave, and through the comparison of the main strain, the authors get the sandcastle shape with the strongest anti-wave impact ability, which is the eccentric circular platform body.Affected by rain: the authors considered the effect of rainwater infiltration on the sandcastle's stress, and simplified the process of rain as a continuous and uniform infiltration of rain into the sandcastle's surface. The rain changes the gravity of the sand on the castle's surface. Simulation analysis is adopted to calculate the surface stress of sand castle with different degree of water seepage and different geometry. By comparison, it has been found that the smooth cone is more able to withstand the infiltration of rain without collapse.
