Feature Selective Validation Application to Effect Analysis of Coiling on the Impedance Profiles of Augmented Cables for IoT Infrastructure
Authors: Ogundapo Olusegun 
Published: August 2024

The increasing demand for Power-over-Ethernet (PoE) applications in Internet of Things (IoT) infrastructure has led to a rise in the use of augmented cables as it is cost-effective. Augmented category 6 (Cat 6a) cable is now the standard for new installations requiring the aforesaid functions. Cat 6a cables for POE applications are required to be able to withstand the effects of repeated coiling they would be subjected to during installation. There is a paucity of literature on the effect of coiling on the impedance profiles of augmented cables across their length. The drawback of the available pieces of literature is that the effect of coiling is based on the frequency of operation. Examining the effect of coiling on the impedance profiles of Cat 6a cables across their length can help determine their physical integrity and aid fault location. Therefore, a method that can be used to examine the effect of coiling on impedance profiles of augmented cables across their length using the Feature Selective Validation (FSV) technique is provided. The ability of the FSV to accurately present the comparison between two data sets as a comprehensible output makes it better than other common methods. Three Cat 6a cables from different manufacturers were selected for the experiment. The Cat 6a cables were exposed to two rounds of coiling and uncoiling to imitate the stress anticipated from handling during installation. The FSV results revealed the cables with the lowest and highest impedance profile variations from the stress tests. The approach presented showed that it can be used to undertake an objective quantification of the effect of coiling on the impedance profiles of the cables across the length.

Authors: Obarisiagbon O.E. , Kayoma D.H. 
Published: August 2024

Background: Routine eye examinations form part of the scope of the health care plan for children to prevent avoidable causes of blindness. This study assessed parents' knowledge of routine eye exam in school children in Evbuomore community and how this affects access to eye examinations.
Methods: This was a descriptive cross-sectional study. Multi-stage sampling technique was employed in the selection of 380 participants in Evbomore community in Edo State. Statistical significance was set at p<0.05.
Results: Atotal of 308 parents with a mean age of 37.4 ±6.1 years participated in this survey. There was poor awareness 46.3% and knowledge 57.9% of routine eye examination in children. Religion (p=0.02), skill level (p<0.01), level of education and monthly income (p<0.01) positively influenced knowledge.
Conclusion: The knowledge of parents regarding routine eye examination in children was poor. Increasing household income, socio-economic status and higher skill levels were significant determinants of good knowledge. These factors can be harnessed by stakeholders in the planning and implementation of health education programs for parents in order to improve knowledge of routine eye examination in children.

INTRODUCTION: Adolescent pregnancy is a global public health challenge, and in Rwanda, though the percentage of adolescent girls experiencing pregnancy has decreased slightly, it remains a concern, particularly in Karongi District, with high incidences. This study aims to identify the risk factors associated with adolescent pregnancy in Karongi district.
METHODS: A case-control study design with a 1:2 ratio of adolescent girls aged 13-19 years was carried out in Karongi District, Western Province, Rwanda. The data were collected using a structured questionnaire and face-to-face interviews. Multivariate logistic regression analysis was performed to identify factors independently associated with adolescent pregnancy. The findings were presented as adjusted odds ratios (aORs) with 95% confidence intervals (CIs).
RESULTS: A total of 522 adolescent girls participated in the study. In bivariate analysis, the majority of variables were significantly associated with adolescent pregnancy. In multivariable analyses, significant factors independently associated with adolescent pregnancy were low socioeconomic status [Ubudehe category 1 (aOR = 4.6, CI = 1.47-14.28), and Ubudehe category 2 (aOR = 5.6, CI = 2.06-14.61)], lack of sexual education from parents/guardians [aOR = 4.5, CI = 1.71-11.82], peer pressure to engage in sexual intercourse (aOR = 3, CI = 1.23-7.32), first sexual intercourse at ≥ 16 years old (aOR = 32, CI = 5.98-88.52).
CONCLUSION: Low socioeconomic status, lack of sexual education from parents/guardians, peer pressure, and first-sex intercourse at ≥ 16 years old were found to be positively associated with adolescent pregnancy. Interventions focusing on increasing parental involvement in sexual health education, supporting low-income families, and addressing peer influence may play a vital role in preventing adolescent pregnancy.

Safety Assessment on the Safety and Efficacy of an Additive of Chromium Propionate (KemTRACE Chromium) as a Feed Additive for All Growing Poultry Species (RP634)
Authors: Food Standards Agency  , Food Standards Scotland  
Published: August 2024

An application was submitted to the Food Standards Agency in March 2021 from Kemin (‘the applicant’) for the new authorisation of an additive (KemTRACE Chromium) containing chromium propionate, under the category ‘zootechnical’ additive, functional group ‘other zootechnical additives’. The additive is proposed to be used at an inclusion rate of 0.2 – 0.4 mg/kg of complete feed (12% moisture) for all growing poultry. The Advisory Committee on Animal Feedingstuffs (ACAF) was asked to review the dossier and the supplementary information submitted by the Applicant, and to advise the Food Standards Agency and Food Standards Scotland (FSA/FSS) in evaluating the dossier. The FSA/FSS concluded, based on the ACAF’s advice, that the additive was correctly characterised, and that it is stable for 24 months at 25oC at 60% humidity, for 6 months as part of a premixture. Homogeneity in feed was also demonstrated. The mixture was pelleted at 90oC, but retention time was not given by the applicant, therefore no conclusion could be drawn on pelleting stability. No further concerns were raised for the identity section, Section II, of the dossier. The proposed level of inclusion in feed is safe for the target species, but no margin of safety could be determined. No conclusion could be drawn on the prenatal developmental toxicity potential of the additive, and therefore, on the safety of the additive for consumers. The additive is non-genotoxic, and no concerns about its metabolism were raised, however, no conclusion could be drawn on the applicant’s proposed 0-hour withdrawal period, given the impossibility to conclude on the prenatal developmental toxicity potential of the additive. The active substance is non-irritant to the skin, however another major ingredient, propionic acid, is corrosive to skin and eyes, and the additive should be considered as such. As the active ingredient is corrosive to skin and eyes and it may be sprayed onto the feed, it would be prudent to regard it as potentially harmful by inhalation. The additive is not a skin sensitizer. The additive poses an acceptable risk to the environment. Chromium propionate has the potential to be efficacious for all growing poultry at the maximum proposed dose of 0.4 mg/kg of complete feed with 12% moisture. The views of ACAF have been taken into account in this safety assessment which represents the opinion of the FSA/FSS.

Public facilities are facilities provided for public purposes such as roads, street lighting, bus stops, sidewalks, and crossing bridges. The facilities provided are facilities that provide convenience for the community so that they must be properly maintained. Pedestrian facilities function to separate pedestrians from vehicle traffic lanes to ensure pedestrian safety and smooth traffic. Hospitals have a classification according to the Regulation of the Minister of the Republic of Indonesia Number 56 of 2004 concerning Hospital Classification and Licensing. This is in line with research conducted by researchers that not all hospitals treat all problems/diseases that arise in sick individuals, there are classifications that have been stated in these regulations. Text mining is text analysis where data sources are usually obtained from documents, and the goal is to find words that can represent the contents of the document so that an analysis of the relationships, linkages and classes between documents can be carried out. The Hospital Classification Information System created can classify hospitals based on the data entered which can be accessed using an Android-based smartphone. This Hospital Classification Information System was created using the K-Means Clustering Method in hospital classification.

Abstract
UPI (Fishing Unit) is a group of fishermen in Payangan waters, Jember Regency that uses conventional tools and methods in the form of attractants made of bamboo. The attractant used is easily washed away by the waves and causes the position of the attractant to move. the use of single-use bamboo attractants can increase the operating costs of the equipment. FIABLE (Fish Attractor Portable) is a technology innovation attractant based on sound frequency and blue lacuba (underwater dip lamp). The power source used comes from the Seawater Wave Power Plant (PLTGL) with a pendulum system that is integrated with IoT (Internet of Things) using aapplication system mobile. The method used is through direct interview surveys to fishermen, FIABLE technology design, technology application and training, and data analysis using Independent Sample t-Test. The results of the attractant test produce a frequency of 1000 Hz with blue light at a wavelength of 450-295 nm. The PLTGL test of the pendulum system can charge a 12 V battery for 3.8 hours. Fishing using FIABLE is proven to work well even with a range of 1 km radius.

This study investigates the perceptions of cocoa farmers in Offinso and Adansi Districts, Ghana, regarding the impact of climate change on their yields, income, and food security. The findings aim to inform policy development and potential mitigation and adaptation strategies. A total of 282 cocoa farmers participated alongside Key Informants. The results indicate a strong consensus among farmers that climate change has negatively affected their yields (0.518 ± 0.501), increased pest and disease prevalence (0.518 ± 0.501), and contributed to cocoa tree mortality (0.482 ± 0.501). This perception is reinforced by the ranking of challenges, where poor yields and increased pest/disease emerged as the most prominent challenges (Relative Importance Index of 0.87 and 0.79, respectively). Interestingly, farmers' perceptions diverged regarding food security. They expressed neutrality towards statements suggesting a negative climate change impact on their food security status (Perception Index = 2.89). These findings highlight the critical challenge of reduced cocoa yield due to climate change for farmers. It is therefore recommended that the Ghana Cocoa Board (COCOBOD), through its extension division, implement immediate actions to educate farmers within the two districts on climate change mitigation strategies. This intervention aligns with achieving the Sustainable Development Goals 1 (No Poverty), 2 (Zero Hunger), and 13 (Climate Action).

Authors: Yahya AL Alrezami Afrah 
Published: August 2024

The current research aims to use non-parametric tests to predict the benefits of switching to e-learning. Non-parametric tests (Chi-square goodness of fit, Chi-square independence and Kruskal Wallis) were used. For the empirical analysis, a questionnaire was used as a tool to collect data and distribute it in 8 Saudi public universities. The research questions included: What are the readiness students of switching to e-learning? What are the most significance indicators of the positive and negative impact of switching to e-learning? The findings indicated that (67.1%) of the students have a high the readiness. It had been seen that the most significance of indicators related to the benefits of switching to e-learning are: (e-learning solves the problem of increasing the number of students, e-learning focuses more on knowledge, it reduces time, it is flexible, e-learning has succeeded in developing programs, e-learning offers topics are well organized, it increases the sharing of experiences between students, assessment methods are fair; and it gives me enough time to think). The most significance indicators related to the challenges, are (e-learning prompted students not to underestimate the education, the professor can identify the negative student, the university provides a virtual library, I have get sufficient training , indirect communication does not affect the understanding , virtual laboratories have been activated, there is no difficulty in submitting exams , the internet is strong in my area, virtual classes are more effective, e-learning helps in exchanging assignments, and the university provides technical support). The findings showed that the course content was the decisive factor of switching to e-learning. The findings can benefit for educators and policy makers for the effective implementation of e-learning in Saudi universities, through attention is paid to all indicators that have a negative impact. And adopting the positive indicators to encourage students to continue e-learning in the future.
