Systemic risks are relevant to most segments of financial and economic activity, which creates the threat of financial instability of enterprises. Financial security, in this case, implies the state of financial soundness; it is expressed through various parameters including the level of solvency, financial stability, business activity, and efficiency of management. These questions are specific to each indicator, and this paper aims to understand their relations and how changes in them can result in risks. It elaborates the risk analysis and assessment procedure that uses a set of common financial analysis tools and determines key financial coefficients. Liquidity ratios, solvency ratios, profitability ratios, and the risk exposure metrics are the key areas that the research is based on. Correlating the financial indicators from a rich dataset from Yahoo’s Stock market data, regression analysis is used to determine these relationships between these indicators and risk management factors. A positive relationship between liquidity ratios and profitability is detected points to the fact that, firms with high liquidity levels are more capable of attaining good financial health and returns. It establishes the need for the development of a credible risk management structure that would lower threats to fiscal and economic activities. In light of this, the research shows that the liquidity and solvency management lowers financial risk and improves return for companies. The regression analysis was conducted to ascertain the degree of predictability of each independent variable to the dependent variable and the findings revealed that approximately 94 percent of each independent variable is predictable of the dependent variable that able to establish as much as 5% of the total variability in profitability, with the PE ratios being an indication of this aspect, was attributed to stock prices, as a result, the firm must be keen on its financials. This paper explores the employability of the proposed methods and models to assess the risks with high accuracy and supports optimum decision making in regard with the needed security of the enterprises. By adopting these methodologies, the businesses can observe and estimate risks which exist in the future which would help them to avoid certain issues or dangers and also pave the way for the improvements of the financial stability of the businesses. On this note, the study establishes the fact that incorporating the notion of total risk management into the framework of analyzing business and making financial decisions is inevitable in maintaining corporate financial stability and realizing perpetual economic solidity. This research enriches the literature on financial risk management, as it outlines viable strategies for the protection of enterprise financial sustainability.

Background: The prevalence of bacterial infections in children is increasing by the day, this gives a cause for concern regarding the high rate of bloodstream infection (BSI) and associated mortality in developing countries. Physical signs and symptoms may be useful but have limited specificity which would be addressed with bacteriologic blood culture. This study was aimed at determining the etiologic agents of bacteremia and the prevalence in pediatric patients aged 0-5years. Methods: Two hundred and sixty- two (262) blood samples were analyzed from children aged 0-5years, attending hospitals within Bauchi metropolis with features suggestive of septicemia. Samples were collected under aseptic conditions and automated blood culture was done on BacT/ALERT 3D Biomerieux, Germany. Positive blood culture was sub-cultured on blood agar and MacConkey agar and identified on Vitek2 (bioMѐrieux, France) automated system after gram staining. Changes in pathogen distribution according to age and gender were determined by the chi-square test and statistical significance confirmed if a two-tailed p-value was not more than 0.01. Results: Bacteria was isolated in 119 (45.4) of samples with highest rate among neonates 54(45.3). Staphylococcus aureus 21 (17.6) was the most predominant organism isolated across all age groups with a higher occurrence in patients<1year old. A chi-square test of independence for culture positivity and age/gender at p<.01 was not significant Conclusion: In this study both Gram-positive and Gram-negative bacteria are implicated in pediatric bloodstream infections. Staphylococcus aureus was the most predominant organism followed by members of the Enterobacterales (Enterobacter spp, Klebsiella spp and Escherichia coli).

The advent of artificial intelligence (AI) has ushered in a new era of efficiency and accuracy across various industries, with inventory management and demand forecasting being at the forefront of these advancements. Traditional inventory management techniques, often reliant on historical data and simple statistical models, fall short in addressing the dynamic and complex nature of contemporary markets (Chopra & Meindl, 2016). AI, with its advanced algorithms and machine learning capabilities, offers a transformative approach to these critical business functions. This paper explores the integration of AI technologies in optimizing inventory management and predicting customer demand. AI-enhanced inventory management involves the application of various AI technologies such as machine learning, natural language processing (NLP), computer vision, and robotics process automation (RPA) (Ivanov et al., 2017). Machine learning algorithms analyze vast amounts of historical data to identify patterns and trends, enabling more accurate predictions and adjustments in inventory levels. NLP processes unstructured data from sources like social media and customer reviews to provide deeper insights into market trends and customer preferences (Cambria & White, 2014). Computer vision technologies assist in real-time monitoring of inventory levels and identifying discrepancies through visual data, while RPA automates repetitive tasks like order processing and inventory tracking, thereby reducing human error and increasing efficiency (Aguirre & Rodriguez, 2017). This paper highlights significant improvements in forecast accuracy and inventory turnover rates achieved through AI implementation and discusses future implications for supply chain management.

Objective. This study aimed to explore the "In Vitro" antimicrobial activity of extracts of leafy stems of M. charantia on a few multi-resistant germs. Methods: Phytochemical screening of M. charantia leafy stem powder was carried out by the methods of colorimetry and thin layer chromatography followed by the search for larval cytotoxicity. The sensitivity test by the solid medium diffusion method and the search for resistance genes were carried out on E. coli ATCC25922 then on K. pneumoniae, K. oxytoca, and E. coli isolated from hospital samples. Flavonoids, alkaloids, stetol-terpenes and saponosides were identified in the powder of the leafy stems of M. charantia. Results: No cytotoxic effects were observed in Artemia salina at the LC 50 of 6.25 mg/ml. With the exception of Ciprofloxacin, Ertapenem and Ceftriaxone which showed respective resistance rates of 60%, 90% and 90%, absolute resistance, i.e. 100%, was observed against Ampicillin, Aztreonam, and Augmentin. The resistance genes present in the bacterial strains studied were SHV, TEM, CTX-M1 and CTX-M15. The sensitivity tests carried out indicate that the aqueous and ethanolic extracts were active on the strains tested with respectively average inhibition diameters of between 9 ±1 and 14 ±1 mM then between 9 ±1 and 12 ±1 mM. Conclusion: This study revealed antimicrobial activity of each of the aqueous and ethanolic extracts of the leafy stems of M. charantia of the multidrug-resistant bacterial strains studied.

Compressed stabilised earth blocks (CSEBs) are produced from inorganic soil compacted under high pressure to create a solid block. This study explores the potential benefits of incorporating coconut coir into CSEBs to enhance their mechanical properties and water absorption. It focused on optimising the mix design of CSEBs with coconut coir reinforcement to achieve maximum compressive strength and minimise water absorption. The study employs a quadratic model to analyse the effects of moisture ratio, cement ratio, and coconut coir content on compressive strength. The results indicate that the moisture content and cement ratio significantly affect compressive strength, while coconut coir content is insignificant. However, the findings suggest that adding coconut coir can reduce water absorption in CSEBs. The analysis of variance reveals that the model is significant, with a predicted R-squared of 0.5884 and an adjusted R-squared of 0.6592. The results contribute to the growing research on using coconut coir as a reinforcement material in CSEBs, offering practical recommendations for their application in building construction.
压缩稳定土块（CSEBs）是由无机土壤经高压压实而成的固体块体。本研究探讨了在 CSEB 中加入椰糠以提高其机械性能和吸水性的潜在好处。研究重点是优化椰糠加固 CSEB 的混合设计，以达到最大抗压强度和最小吸水率。研究采用二次模型分析了水分比、水泥比和椰糠含量对抗压强度的影响。结果表明，水分含量和水泥比对抗压强度有显著影响，而椰糠含量则不显著。然而，研究结果表明，添加椰糠可以减少 CSEB 的吸水率。方差分析显示该模型是显著的，预测 R 方为 0.5884，调整 R 方为 0.6592。这些研究结果有助于推动在 CSEB 中使用椰糠作为加固材料的研究，并为其在建筑施工中的应用提供了实用建议。

The aim of this work is design and implementation of a lecture alert system for Computer Science Department which makes use of Short Message Service (SMS) to enable lecturers to know when they have lectures and also deliver the venue, department, day, date and time to their phones. The motivation for this work is due to the challenges of the consistence report of errors in the process of filling and allocating the lectures on the time table, lack of effective record system or database system to store the record of time table and clashes of lecture because one venue can be allocated to different lecturers at the same time. The methodology that will be employed in this study is the object-oriented analysis and design methodology (OOADM) which will make use of the following programming languages; JavaScript for controls and flexibility, PHP for effective linking and communication with the database machine, HTML for browser communicator, a database machine, MySQL, and macromedia flash (11.0) for the video output display. The expected result that will be obtained is to a design a conventional lecture alert system using Short Messaging Service (SMS), also to provide a new method of checking lectures using mobile phone short messaging service work and to alert students ahead of their lectures and inform them of the venue of the lecture.

The expected result that will be obtained is to a design a conventional lecture alert system using Short Messaging Service (SMS), also to provide a new method of checking lectures using mobile phone short messaging service work and to alert students ahead of their lectures and inform them of the venue of the lecture.","PeriodicalId":23739,"journal":{"name":"World Journal of Advanced Research and Reviews","volume":"9 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite numerous reforms, the Judiciary of Kenya has seen a rise in complaints about its service delivery. Common issues include slow service, missing files, corruption, delayed rulings, and delayed orders. This increase in complaints is surprising given the efforts to improve the judiciary's service delivery. Consequently, it is important to examine the planning strategies within the Judiciary and how they impact service delivery. This area has rarely been studied, leading to a lack of understanding in the existing literature about the effects of planning on service delivery in Kenya's Judiciary. This study aimed to fill that gap by focusing on the Meru High Court. The study aimed to examine the impact of planning strategy on service delivery at the Meru High Court, with a target population of 86 respondents. The research was guided by Kotter’s Eight Step Change Model. A descriptive survey design was employed. Before collecting the main data, a pilot test with 9 respondents was conducted at the Chuka Law Courts to assess the questionnaire's reliability and validity. Data analysis involved descriptive statistics such as frequency distribution, percentages, mean, and SD, along with regression and correlation analyses. The findings showed that a plan is created prior to implementing any changes. Respondents confirmed that the information provided by the Judiciary regarding changes is both reliable and pertinent. The research is significant as it helps the Judiciary understand how planning strategies affect service delivery.

Sepsis after caesarean section (CS) is still a major problem in our hospitals. A large percentage of caesarean section wound infections arise from preventable causes which if addressed could significantly reduce rate of wound sepsis. The aim of this study was to identify the prevalence of bacterial pathogens associated with post caesarean wound infections and determine their relationship with some risk factors. A prospective descriptive study was conducted in randomly selected hospitals in Otukpo which included 278 women (mean age; 26.94) who underwent surgical procedure for delivery. Data were collected from patients following wound examination and compared in terms of surgical site infection and study variables (age, parity, type of CS, type of incision, duration of hospital stay and duration of Labour. Out of the 278 caesarean sections, 187(67.3%) were emergency procedures and 91 (32.7%) were elective procedures. Twenty three of the cases developed surgical site infections (SSI). Staphylococcus aureus (n=11; 47.83%) was the most commonly isolated organism followed by E. coli (n=5; 21.74). Caesarean section infection was found to be common in women who had emergency CS (p<0.0001), who had longer duration of Labour and hospital stay (p<0.0001) and had sub-umblical type of skin incision (p<0.0001). Development of infection following caesarean section is multifactorial and can be minimized or prevented if health care professionals develop and implement strict protocol for performing caesarean sections.
