Introduction. The collection and analysis of anthropometric and body composition data from different regions is essential for anthropological, medical, and epidemiological research. These data make it possible to assess the state of physical development at the individual and population levels, as well as adapt prevention and treatment strategies to the specific needs of different population groups. Our study aimed to investigate age- and sex-related variability in height, weight, body mass index (BMI), body composition, and phase angle among residents of the Russian Federal Territory Sirius using bioelectrical impedance analysis data. Materials and methods. In 2021–2025, a non-clinical cross-sectional observational study was conducted of 1,699 conventionally healthy individuals aged 5 to 73 years who visited annual sports and cultural events organized for residents of the Federal Territory Sirius. Of these, 812 were male and 887 were female. Measurements were taken using InBody 770 body composition analyzers and InBody BSM 370 digital height meters (Biospace, Seoul, Republic of Korea). Using the RefCurv software ver. 0.4.2 and the built-in LMS method, centile tables of the above-mentioned traits were constructed depending on age and sex. Sex differences in these traits were assessed in different age groups. The obtained centile curves were compared to WHO growth reference data for 5-19 years and to nation-wide reference data from Russian health centers. Results. Average height was found to be relatively high among young men, reaching up to 181.2 centimeters. BMI data generally followed the WHO growth references, with some slight upward differences for males and downward differences for females beginning in the second childhood period. During puberty, boys experienced accelerated musculoskeletal development, while girls experienced significant development of adipose tissue. After the initial growth phase, the decrease in percentage of skeletal muscle mass started early in life, at the age of 13–14 for females and at the age of 18–20 for males. A gradual increase in the percentage of fat mass was observed in adults, while fat-free mass and skeletal muscle mass remained relatively stable during the first and second periods of mature age. Phase angle was higher among males across all age groups, reaching a peak around 28–30 years for males and 30–35 years for females, and then gradually declining. Conclusion. For the first time, age- and sex-related reference values for anthropometric measurements, BIA body composition, and phase angle are developed for residents of the FT Sirius. These data can be used as a proxy for establishing regional standards for physical development and monitoring population health. Our future efforts will focus on conducting a more detailed medical and biological examination of the population, with random sampling, expansion of age range, and an increased number of traits studied, including segmental body composition and bilateral asymmetry. This would allow for the improvement of regional standards for a better understanding of interindividual differences and the development of personalized physical activity programs.
В работе изучается асимптотика решения задачи Дирихле для оператора Лапласа в области, полученной из бесконечной горизонтальной полосы присоединением вертикальной бесконечной полуполосы малой ширины. Методами теории потенциала задача сводится к интегральному уравнению на границе области. К полученному уравнению применяется альтернирующий метод Шварца в подходящем банаховом пространстве. Решение выражается через "операторы отражения". Формулу для одного из таких операторов удается получить лишь при дополнительных ограничениях на правую часть уравнения, заключающихся в конечности некоторых весовых норм. Библиография: 11 названий.

A fully functional algorithm for assessing the effectiveness of learning the design modules based on PCB in intelligent adaptive systems is determined by the step of technological operations to ensure the uniformity of the learning quality control. Conclusion. This system can be useful for teachers and specialists-studying the design modules based on PCB. This system can be used at the stage of assessing the achievable characteristics which can significantly speed up the learning process. The research methods are applied in training the design modules based on PCB to the personnel of the shipyard X52 in Vietnam. It is suitable not only for training shipyard personnel to work, for teaching various levels of training of personnel of any industrial enterprise, for example, in aircraft engineering, mechanical engineering or instrument making, and for teaching any CAD system in general.

С использованием обобщения понятия классической вейлевской $m$-функции, а также связанных с ним формул для резольвент операторов краевых задач изучается асимптотическое поведение решений "задачи трансмиссии" для высококонтрастного включения в непрерывной среде. Для указанной задачи показана сходимость по норме разности резольвент к предельной задаче "электростатического" типа. В частности, результаты работы влекут за собой сходимость спектров семейства задач с высоким контрастом к спектру предельного оператора с точной оценкой скорости указанной сходимости. Разработанный нами метод является общим и потому может успешно применяться и в других задачах этого типа. Библиография: 34 названия.
