Authors: ПОЛЯКОВ Д В. , ВЕЛЕГУРИНА Е Ю. 
Published: July 2024

В статье предложен алгоритм построения структуры данных на основе ограниченного сверху диапазона натуральных чисел. Эта структура позволяет осуществлять факторизацию чисел из данного диапазона в худшем случае за логарифмическое время и проверку на простоту за константное. Сопутствующим эффектом построения предложенной структуры является нахождение всех простых чисел в заданном диапазоне и представление их в виде двусвязного списка. В работе приведена оценка асимптотической сложности всех предложенных алгоритмов, в том числе показано, что асимптотическая сложность построения предложенной структуры не превышает линейную. Предложен подход к использованию построенных алгоритмов и структуры данных для реализации длинной арифметики в факторизованном виде. Рассмотрен класс прикладных задач, для решения которых целесообразно использовать длинную арифметику в факторизованном виде с предложенным алгоритмом факторизации.
In the article an algorithm for constructing a data structure is given which based on a range of natural numbers limited from above. This structure allows factorization of numbers from a given range in the worst case in logarithmic time and checking for primality in constant time. A side effect of constructing the proposed structure is to nd all prime numbers in a given range and represent them as a doubly linked list. The paper provides an estimate of the asymptotic complexity of all proposed algorithms, including showing that the asymptotic complexity of constructing the proposed structure does not exceed linear. An approach to using the constructed algorithms and data structure to implement long arithmetic in factorized form is proposed. A class of applied problems is considered, for the solution of which it is advisable to use long arithmetic in factorized form with the proposed factorization algorithm.

Published: July 2024

The herbaceous Belugas leaves (Pluchea indica L.) belong to the Asteraceae family and are commonly utilized as food and hedges. They typically grow wild. Alkaloids, saponins, flavonoids, tannins, triterpenes, and steroids are among the substances found in belugas leaves that may have insecticidal properties. The purpose of this study is to use the leaf extract of Beluntas (Pluchea indica L.) as a foundational component for liquid mosquito repellant. In order to produce a thick extract of beluntas leaves, this study used an extraction process that involved evaporating 96% ethanol solvent. Several concentrations of the thick extract were diluted, including 15%, 25%, 35%, 45%, and 55%. The collected data, which was mosquito mortality, was subjected to a One-Way Anova test with a significance level of p = 0.000 <0.05, and then the Duncan test. The findings demonstrated that the number of mosquitoes that perished varied depending on the concentration fluctuations of beluntas leaf extract, with the highest concentration of beluntas leaf extract killing mosquitoes at a rate of 55% and a mosquito mortality percentage of 98.4%.

This article investigates the ways in which language is employed in the construction of social power in selected institutional discourses. Speech acts theory and Fairclough’s concept of language and power serve as the study’s theoretical anchor. Data were generated through (non)participant observations in a five-year fieldwork to examine the peculiarities in instantiating social power using specific terms in workplace interactions involving participants with unequal power derived from the social roles they perform within the scope of this study. During the period, institutional discourses that demonstrate the enactment of social power in medical, religious, political, legal, academic and security domains in Calabar Metropolis, South-south Nigeria, were closely observed and documented. The linguistic choices show institutional and power differentials in the rehearsal of social power among discourse participants where one wields more than the other(s). Social power, as demonstrated, is dynamic and excised using the domain’s registers and enacted towards the punishment, reward, confinement, reformation, freedom or general wellbeing of the recipient. The study enriches the understanding of how social power holders rely on inferred authority and certification from their professional affiliations and work conventions to construct and maintain social power.

Published: July 2024

Diabetes mellitus and metabolic disorders are the priority programs in Indonesia. There is one program to reduce the fatality impact of diabetes which is diabetic self-management education (DSME). This study aimed to examine the effectiveness of Diabetes Self-Management Education (DSME) on dietary habits, physical activity, and obesity. This study is a quasi-experimental approach with one group pre-test post-test design. The sample in this study was 75 people with DM type II. The intervention for all samples was done for 4 sessions. Each session lasted 60 to 120 minutes/day with a maximum of 10 patients. The findings revealed that dietary habits were good from 56.0% to 69.3%, physical activity was good from 54.7% to 76.0%, and obesity decreased from 69.3% to 57.35, respectively for pre and post-test. The paired t-test result revealed that DSME correlates with dietary habits, physical activity, and obesity (obesity, physical activity, and dietary habit with p-values 0.024; 0.007; and 0.02, respectively). In conclusion, DSME has significantly influenced dietary habits, physical activity, and obesity. Education is crucial in promoting physical activity among individuals with diabetes. By enhancing self-efficacy, providing education on self-care behaviors, and emphasizing the importance of regular physical activity, these programs contribute to improving metabolic control, quality of life, and overall health outcomes in diabetic patients.
