Authors: Harold I. , Okpara K. , Harold A.I.
Published: March 2024

Introduction. Early sexual initiation is the art of initiating sexual activity before age 15. This study aimed to identify the burden and predictors of early sexual initiation among school-­going adolescents in rural settlements in Rivers State, Nigeria. Materials and Methods. A cross-­sectional study was conducted among 420 school-­going senior secondary school adolescents of coeducational schools aged 15–19 from May 2023 to September 2023. A multi-­stage sampling procedure was used to select respondents from four senior secondary coeducational schools. Data were collected using a semi-structured interviewer-­assisted questionnaire. Frequency tables were generated and Logistic regression analysis was used to determine predictors of early sexual initiation at a 5% level of significance. Results. The mean age of respondents was 15.7 ± 0.8 years. The mean age at early sexual initiation was 12.2 ± 1.2 years. The burden of early sexual initiation and ever-had sex among the respondents was 46% and 54.8% respectively with poor academic performance, school dropout, STI infection, pregnancy, and HIV infection experienced as outcomes of first sexual initiation among the respondents. The statistically significant predictors of early sexual initiation were adolescents having worked for pay, currently working for pay, and adolescents’ age at first sexual partner (OR = 4.6; 95% CI = 1.6–12.7; P = 0.004, OR = 6.6; 95% CI = 1.9–23.7; P = 0.003 and OR = 3.1; 95% CI = 1.3–7.2; P = 0.009). Conclusion. Sexuality education and programmes aimed at encouraging school-­going adolescents to delay first-sex initiation should be encouraged.

Bronchogenic cyst is a rare congenital anomaly of the formation of the pulmonary germ, a thin–walled formation filled with thick contents, which distinguishes it from aerial bronchial cysts. Clinically, a bronchogenic cyst can manifest itself as obstructive respiratory failure, swallowing disorders, and lead to recurrent purulent-­inflammatory processes. In this article, we present a clinical case of bronchogenic cyst in a newborn child, detected during pregnancy at the 2nd ultrasound screening and successfully operated on as planned. A 5-day-old boy was transferred to a surgical hospital for surgical treatment of cystic formation of the left lung S10 with dimensions 16.0×12.0×15.0 mm; the cyst contents were homogeneous, corresponding to the fluid. Surgical treatment was performed — the formation was separated from the parietal pleura and sent to the pathology department for histological examination. No complications were observed in the postoperative period. The macroscopically studied object was a three-­dimensional formation of gray-red color with a bluish tinge of irregular shape, dull, with a dark red fine sprinkling. A thin-walled cavity filled with cloudy jelly-like contents was determined on the incision. Microscopic description — a cyst lined with ciliated epithelium, partially flattened to cubic due to dystrophic changes, subepithelial islets of mature cartilage tissue and small groups of mucous glands. Thus, a bronchogenic cyst was morphologically verified. Differential diagnosis of bronchogenic cysts from inflammatory lung diseases (tuberculosis, abscess) with untimely diagnosis in the absence of clinical manifestations is practically impossible without histological examination. Therefore, prenatal diagnosis and morphological examination of the surgical material are crucial.

Published: March 2024

Concern regarding secular trend of declining age of menarche has increased in the last few decades. Prevalence of childhood and adolescents obesity in Indonesia has also increased lately while some studies suggest that increased body mass index associates with the early onset of puberty which known to be the risk factor of many health problems. This study aims to investigate whether age of menarche is associated with body mass index in adolescents in Palembang. Sample of this cross sectional designed study was elementary and junior high school girls from 8 schools in Palembang taken with stratified random sampling. A total of 388 respondents met the inclusion criteria. Age of menarche and body mass index got from the questionnaire and anthropometric examination were analysed using Chi-square test. Out of 388 respondents, 49.5% experienced menarche at the earlier age than the mean age of menarcheof 12.36 years and 20.1% were classified as overweight and obese. The average menarcheal age of overweight and obese respondents was earlier than those classified as normal and underweight. This study proved that there is a highly significant association between age of menarche and body mass index with the p-value of 0.000 (Chi-squaretest). There is a highly significant association between body mass index during peripubertal period and the age of menarche. Strict monitoring on body mass index of elementary and junior high school girls is necessary to prevent early puberty.

Authors: Koigerov A. S. , Korlyakov A. V.
Published: March 2024

Introduction. Bandpass filters on surface acoustic waves (SAW) are important components in frequency selection devices for receiving and transmitting electronic equipment. Among the variety of existing requirements for SAW filters, particular attention is paid to those for the quality of characteristics, including reduction of insertion losses, unevenness in the bandwidth, etc., and those for reducing the development time of the filter. Reduction in the development time along with a simultaneous reduction in expenses can be achieved through the application of preliminary computer simulation. This task can be implemented only through an integrated approach to developing a computer-aided design system capable of solving optimization problems with a large number of degrees of freedom.

Aim. Development of a prototype of a fully functional complex for simulating and calculating SAW filters. Approbation of work on the creation of actual frequency filters on the example of resonator SAW filters with low losses on leaky SAWs. Development of a methodological approach to creation of a technology of computer-aided design of SAW filters using optimization algorithms.

Materials and methods. The theoretical part of the work was carried out using statistical analysis methods, circuit theory, and coupled mode theory. In the course of the work, mathematical processing and calculation were carried out in the MATLAB environment.

Results. A concept for creating a system of automated design of SAW filters with specified frequency characteristics was developed. An original method is proposed for optimizing the topology of SAW filter elements to obtain the maximum achievable frequency responses. The proposed approach was tested when calculating a resonator filter on leaky SAWs at 64° YX-cut lithium niobate.

Conclusion. The proposed integrated approach to designing SAW filters allows a rapid and relatively accurate prediction of filter characteristics at the modeling stage, which has a significant advantage compared to conducting numerous real experimental studies or numerical studies in the presence of a large number of degrees of freedom.

Authors: Bobkov I. V. , Yukhanov Yu. V.
Published: March 2024

Introduction. The conventional approach to extending the operating frequency band of Vivaldi antenna arrays consists in increasing the radiating element length. However, this inevitably leads to an increase in the mass of the entire array, and, therefore, to a rapid growth in the cross-polarization level. Recent studies in this field have mainly focused on techniques for reducing the cross-polarization level. At the same time, the possibility of developing Vivaldi antenna arrays with an extended operating frequency band, primarily without changing the overall dimensions of the elements or the antenna array pitch, remains insufficiently studied.

Aim. Design and study of the Vivaldi antenna radiating element that ensures operation of the array in a wider operating frequency band without increasing its overall dimensions and weight.

Materials and methods. A numerical study of the characteristics of a unit-cell with periodic boundary conditions on the side faces was carried out in the ANSYS HFSS software. A comparative analysis of the unit-cell characteristics of the prototype antenna array and the proposed design was carried out.

Results. The design of the Vivaldi antenna radiating element is presented. The influence of some geometric parameters on the characteristics of the antenna array is studied. A comparative analysis of the unit-cell characteristics of two infinite single-polarization antenna arrays based on a regular Vivaldi element and the proposed solution is carried out. The possibility of improving the antenna array bandwidth by 18.6 % and improving cross-polarization by 15 dB on certain frequencies without increasing the overall dimensions or the antenna array pitch is shown.

Conclusion. The proposed Vivaldi antenna design makes it possible to extend its operating frequency band without increasing the overall dimensions. The results of the conducted numerical study should be used when developing antenna arrays based on the proposed solution.

Published: March 2024

With the continued changes in the way businesses work, cyber-attack targets are in a constant state of flux between organizations, individuals, as well as various aspects of the supply chain of interconnected goods and services. As one of the 16 critical infrastructure sectors, the manufacturing sector is known for complex integrated Information Systems (ISs) that are incorporated heavily into production operations. Many of these ISs are procured and supported by third parties, also referred to as interconnected entities in the supply chain. Disruptions to manufacturing companies would not only have significant financial losses but would also have economic and safety impacts on society. The vulnerabilities of interconnected companies created inherited exploitations in other interconnected companies. Cybersecurity practices need to be further enhanced to understand supply chain cybersecurity posture and manage the risks from lower-tier interconnected entities up to the top-level dependent organization. This paper will provide an overview of the Theory of Cybersecurity Footprint to emphasize the relationship among interconnected entities and the cybersecurity effects one organization can have on another regardless of size. This paper provides a literature review on the manufacturing industry with a recommendation for future developmental research using the Delphi method with a panel of experts to develop an index to measure cybersecurity posture based on interconnected entities from lower tiers and establish index weights specifically for the manufacturing industry.
