Authors: Pasisingi Nuralim , Olii Abdul Hafidz , Kadim Miftahul Khair 
Published: December 2024

Objective: Providing information on the perspectives of local communities and fishers living around the nike fishing area regarding the Bone Estuary Protected Area implementation plan.

Theoretical Framework: Previous studies have examined biology, ecology, socio-economics, and technology for catching nike resources in Gorontalo. Policy and regulation are also essential aspects that need to be implemented as a form of biodiversity and habitat conservation.

Method: As the primary respondents, local communities and fishermen were directly involved in the Estuary Protected Area plan. Data collection was carried out through in-depth structured interviews and observations using questionnaires.

Results and Discussion: The local community and fishermen agree with the Bone Estuary protection plan to maintain the sustainability of the nike fish. However, restrictions on fishing gear, time, and area have not been entirely accepted to preserve the nike population due to their ignorance of the importance of the nike life cycle in supporting population recruitment.

Research Implications: This study serves as fundamental insights for stakeholders to develop and implement technical strategies to sustain nike fish resources by protecting the Bone Estuary. Engaging community or traditional leaders is crucial to facilitating communication between the government, scientists, and local residents, fostering responsible participation to ensure the success of the protected area.

Originality/Value: Local communities and fishermen residing in the Bone Estuary area have expressed partial disagreement with implementing the Bone Estuary Protected Area plan.

Authors: Kondakova A. P. , Platonova Z. N. 
Published: December 2024

Introduction. Childhood obesity is a pressing public health problem worldwide. According to WHO, in 2022, there were 390 million overweight children and adolescents aged 5 to 19 years in the world. Experts consider this problem not only from a somatic point of view, but also from a psychological component.The objective was to identify the features of adaptive resource potential, personal anxiety and the specifics of parental attitudes of overweight and obese adolescents.Methods and materials. A total of 120 respondents took part in the study, including 30 overweight and obese adolescents and 30 their parents. The comparison group consisted of adolescents with a normal body mass index and their parents. Psychodiagnostic survey techniques were used aimed at studying adaptive resource potential, the level of personal anxiety and the specifics of parental attitudes.Results. It was revealed that overweight and obese adolescents highly value their external adaptive potential more than their internal individual psychological adaptive potential. The level of psychological stability is most based on the external system: support from the family, friendly relationships with peers. In assessing the level of manifestation of personal anxiety in adolescents, a low level of anxiety is observed, possibly as an external manifestation of a defense mechanism. In the system of child-parent relations among overweight and obese adolescents, there is a tendency to display negative feelings, low control, and perhaps a more permissive attitude towards the process of raising and educating the child.Conclusions. For overweight and obese adolescents, correctional and developmental classes should be conducted on self-regulation of their emotional state, increasing self-esteem, accepting their individual psychological qualities, as well as psychological work with the parents of adolescents, in general, with the family system.

Introduction. The creation of new compounds with pronounced cytotoxic activity is one of the priority goals in modern medicinal chemistry due to the emergence of multidrug resistance (MDR) to existing chemotherapy drugs for many types of tumour diseases.The objective was the synthesis of DNA-tropic heterocyclic systems containing a quaternized nitrogen atom and one or two styryl moieties as side chains. The synthesized compounds must have pronounced cytotoxic activity and moreover bind with DNA macromolecules effectively.Methods and materials. In this paper, 2 new compounds containing a 10-methyl substituted pyrimidobenzimidazolium core and 1 or 2 4-dimethylaminostyryl moieties as side chains were synthesized. The structures of targeting compounds were confirmed using mass spectrometry and NMR spectroscopy methods. The electronic spectra of these compounds were studied in this work. The investigations of targeting compounds proved their ability to bind with DNA macromolecules. The cytotoxicity of the synthesized compounds was studied on four cell lines.Results. The target compounds were obtained in four-stage synthetic procedure. The purity of the target products was confirmed using NMR spectroscopy and mass spectrometry. The synthesized compounds are effective cyanine dyes with absorption maxima in the dark red and dark violet regions of the visible spectrum for mono and bis 4-dimethylaminostyryl derivatives, respectively in the its electronic absorption spectra. Both of the synthesized compounds can form a stable complex with DNA macromolecules with a significant deepening of the colour in the solutions. The compounds showed pronounced cytotoxic activity in in vitro experiments on a number of cancer-transformed cell lines. The target compounds were shown a high cytotoxic activity against triple-negative breast cancer cells, which are extremely resistant to chemotherapy.Conclusion. 4-Dimethylaminostyryl derivatives of N-methyl-pyrimidobenzimidazolium iodides require a further study as new promising compounds with pronounced antitumor activity.

Published: December 2024

Improving the vibration isolation performance of the helicopter’s main gearbox strut can reduce the vibration level transmitted to the aircraft body and the level of structural noise radiation. This article proposes a piezoelectric stack periodic strut (PSPS) scheme based on the piezoelectric stack and rubber periodic arrangement. Piezoelectric stack actuators can achieve active vibration and noise control, and the periodic structure of the piezoelectric stack actuators and rubber also has wideband stopband characteristics for reducing vibration and noise. Therefore, PSPS has active and passive hybrid control capabilities, which has advantages in vibration and noise reduction performance, the power of active control, volume and mass, etc. This article presents a full-parameter model that can describe the electromechanical coupling dynamic performance of PSPS. The correctness of the model was verified by the finite element software, and the concept of optimal isolation potential of PSPS was proposed and evaluated. Finally, the hybrid control capability of PSPS for single-frequency and wide-frequency noise was verified through experiments. The results show that compared with the noise level of the cabin using an ordinary strut, PSPS has wideband vibration reduction and noise reduction performance above 500 Hz, with a maximum noise attenuation exceeding 25 dB. When applying active noise control to the PSPS on the helicopter model, a control effect of 12.63–15.56 dB at 900 Hz was achieved.

Published: December 2024

Objectives:
Age estimation is an integral part of legal investigations for forensic purposes. When the chronological age of the individual is not documented or he/she is under the conflict of the law, age estimation comes into play. The need for age estimation may arise in various legal incidences involving children, and juveniles, for civil aspects such as adoption, child labor, or other criminal proceedings such as rape, kidnapping, and illegal immigration. An accurate and dependable method, that can estimate age with high probability, can aid in narrowing down the list of possible victims or even play a decisive role in such cases. The reliability of the method and the probability of correct age estimation play a decisive role in the court of law. Bedek et al’s model (2019) was recently developed and tested in Croatian and South Indian populations with satisfactory results. As there is no evidence of study in the Western Indian population, looking into the accessibility of the population group, the present study aims to evaluate the validity and reliability of the Bedek method in the Western Indian population.

Materials and Methods:
Approval was sought from the Institutional Ethical Committee. Five hundred and twenty-five orthopantomographs (OPG) of patients aged 5–15 were obtained. A double-blinded study was done, where the radiographs were analyzed using ImageJ software, independently by two investigators. The data were tabulated and subjected to statistical analysis for accuracy of age estimation and intra- as well as inter-observer reliability.

Results:
There was an underestimation by a range of −1.3038 to −0.74536. There was underestimation in all the models of Bedek with P < 0.005, for all the teeth models except, the three- and two-teeth model (P > 0.005).

Conclusion:
In our study, we found that the accuracy of age estimation increases significantly with the number of teeth used. Seven four-teeth models were the most suitable for age estimation on OPG. All models except the three-teeth model and two-teeth model were found to be more accurate.

The article examines the situation of online media as a new challenge to the ideology of the Tajik state. At the same time, the main emphasis is on the formation of a network society and its impact on the transformation of the political life of the country as a whole. The social and economic foundations of the strategy of control over online media are revealed. On this basis, the main trends in the development of online media and the media strategy formed in relation to them are determined, creating an appropriate communication space focused on preserving information security. The results and conclusions of the proposed study are based on original sources, empirical data and comparative studies of Tajikistan in the context of the countries of the Central Asian region. This aspect also includes the study of sociological and journalistic investigations, both regional and international organizations. The empirical basis of the study is also the materials of online media and the content of laws that define Internet content in the country. The conceptual basis of the study is that the emergence of online media in modern Tajikistan has contributed to the establishment of a less regulated information network space in the country, but the political regime of censorship and control over the media seeks to make this system integrative and sends all opposition views to the periphery.

В работе анализируются каналы глав регионов Российской Федерации. Исследование каналов было разделено на 4 этапа: отбор каналов, сбор статистической информации, выгрузка сообщений и обработка текстовой информации. Для сбора данных был использован инструмент TGStat. Вся полученная информация была сохранена в единую базу для сравнительного анализа. Фиксировались такие параметры, общее количество подписчиков, индекс цитирования, средний охват одной публикации, общее количество публикаций, доля читающих подписчиков. Дополнительно, были проанализированы даты создания каналов и установлено, что более половины исследуемых каналов было создано в марте 2022 года. Итоговая база выгруженных сообщений составила 98,5 тыс. постов. Была поставлена задача автоматически определить, какие темы упоминаются в текстах имеющегося набора данных. Для этого был применен алгоритм решения задач кластеризации текста. В результате кластерного анализа сообщений были выделены 13 тематических кластеров, описанных ключевыми словами. Таким образом, полученные данные позволяют оценить основные темы, которые освещаются в аккаунтах официальных лиц. Пилотное исследование проведено в рамках проекта РНФ, реализуемого в Центре технологий электронного правительства Института дизайна и урбанистики Университета ИТМО, ориентированного на изучение специфики электронного взаимодействия органов власти с гражданами на региональном уровне.
The paper analyzes the channels of the heads of regions of the Russian Federation. The research of channels was divided into 4 stages: selection of channels, collection of statistical information, unloading of messages and processing of text information. The TGStat tool was used to collect data. All the information received was stored in a single database for comparative analysis. The following parameters were recorded: the total number of subscribers, the citation index, the average coverage of one publication, the total number of publications, the share of reading subscribers. Additionally, the dates of channel creation were analyzed and it was found that more than half of the studied channels were created in March 2022. The total base of unloaded messages amounted to 98.5 thousand posts. The task was set to automatically determine which topics are mentioned in the texts of the existing dataset. For this, an algorithm for solving text clustering problems was applied. As a result of cluster analysis of messages, 13 thematic clusters were identified, described by keywords. Thus, the data obtained allow us to evaluate the main topics that are covered in the accounts of officials. The pilot study was carried out as part of the RSF project, implemented at the E-Governance Center of the Institute of Design and Urban Studies ITMO University, focused on studying the specifics of electronic interaction between authorities and citizens at the regional level.
Синтез нелинейного наблюдателя для оценивания динамических сбоев с применением спектральной H∞-оптимизации
Authors: Князькин Я.В. 
Published: December 2024

В представленной работе рассматривается задача синтеза наблюдателей - фильтров для оценивания воздействия аддитивных динамических сбоев в системах с липщицевой нелинейной частью. За счет выбора параметров асимптотического наблюдателя-фильтра обеспечивается его невосприимчивость к внешнему возмущению, в том числе обладающему известными спектральными свойствами. В основе предложенного метода лежит специальный спектральный подход в частотной области, использующий параметризацию множества передаточных функций замкнутой системы, дробно-рациональную матричную интерполяция и условие асимптотической устойчивости нулевого положения равновесия динамики ошибки оценивания. Предложен новый метод аналитического синтеза адаптивного нелинейного наблюдателя для оценивания воздействия динамических сбоев, эффективность которого продемонстрирована на практическом примере – движении морского судна в горизонтальной плоскости с постоянной скоростью под действием морского волнения. Для проведения имитационного моделирования динамики судна используется среда MATLAB.
The presented paper is devoted to the problem of the fault estimation observers design in case of plants with the Lipschitz system nonlinearity. Insensitivity of the observer to external disturbances, including ones with the given spectral properties, is to be guaranteed by the choice of its parameters. The proposed method is based on the special spectral approach in frequency domain, using parametrization of the set of transfer functions of the closed-loop system, Nevanlinna-Pick rational function interpolation and the condition of asymptotic stability of the zero equilibrium position of the estimation error dynamics. A novel approach to analytical synthesis of the adaptive nonlinear fault estimation observer is proposed, and its effectiveness is demonstrated on the practical example – the marine ship horizontal motion with the constant longitudinal speed under the sea waves action. The MATLAB package is used for numerical simulation of the ship dynamics.
