Après avoir longtemps effleuré l’idée de décentralisation, la République démocratique du Congo a franchi le pas : la constitution qui a créé en 2006 la IIIème République instaure un système institutionnel ou les régions se voient attribuer un rôle pivot dans l’administration du territoire. La décentralisation devient un principe constitutionnel et les articles relatifs aux régions et à leur champ de compétence traduisent un régionalisme volontariste. Mais pour comprendre cette décentralisation, il importe d’aller au-delà du texte et de la replacer dans son contexte de court et long termes. Elle devient alors plus ambiguë, voire change complètement de sens au point qu’on peut se demander si cette décentralisation n’est pas, en réalité, une recentralisation. De ce fait, bien que les compétences des provinces forment un inventaire hétéroclite et qu’elles disposent de l’autonomie budgétaire, leurs pouvoirs effectifs actuels, ainsi que ceux des autres entités territoriales décentralisées apparaissent dans la pratique comme une antithèse de ce qui est sur le papier. A rebours de la décentralisation, les collectivités décentralisées congolaises sont entrain de jouir de non pas plus mais moins de pouvoirs à l’aune de l’écart entre droit et réalité.
A busy place such as a market is one to consider circulation for as movement in a facility is continuous whenever it is in use. One would want to also want to pay attention to fire safety as well because it is part of the primary consideration to protect life and properties. Fire safety and movement in an ultra modern market is a quintessential priority as in the case of fire emergency, the means of circulation provided will aid egress and may determine a level of safety that will be attained. Data collections were achieved through studies from different publications and a case study. Ultra modern markets in Nigeria are still evolving as there are not many to lay hold on. The way to handle cases of circulation and fire safety are careful considerations from design standards and process which would be carefully implemented during construction. Proper measures should also be put in place to supervise the fire safety, ensuring that they are all in place. Keyword- Market, circulation, fire safety.
In recent years, the importance of career guidance for senior high school students has gained significant attention. This study examined the factors that influenced the course preferences among senior high school students, including personal interest, parental influence, and support systems. Using a descriptive survey design, quantitative data was collected from 174 Grade 11 students from Southern de Oro Philippines College through random sampling.

Breast cancer (BC) is the most frequently diagnosed cancer in women worldwide with more than 2 million new cases in 2020.Its incidence and death rates have increased over the last three decades due to the change in risk factor profiles, better cancer registration, and cancer detection.The number of risk factors of BC is significant and includes both the modifiable factors and non-modifiable factors. Currently, about 80% of patients with BC are individuals aged >50.Survival depends on both stage and molecular subtype.Invasive BCs comprise wide spectrum tumors that show a variation concerning their clinical presentation, behavior, and morphology.Based on mRNA gene expression levels, BC can be divided into molecular subtypes (Luminal A, Luminal B, HER2-enriched, and basal-like).The molecular subtypes provide insights into new treatment strategies and patient stratifications that impact the management of BC patients.The eighth edition of TNM classification outlines a new staging system for BC that, in addition to anatomical features, acknowledges biological factors.Treatment of breast cancer is complex and involves a combination of different modalities including surgery, radiotherapy, chemotherapy, hormonal therapy, or biological therapies delivered in diverse sequences.Body fatness is a dynamic exposure throughout life.To provide more insight into the association between body mass index (BMI) and postmenopausal breast cancer, we aimed to examine the age at onset, duration, intensity, and trajectories of body fatness in adulthood in relation to risk of breast cancer subtypes.Based on self-reported anthropometry in the prospective Norwegian Women and Cancer Study, we calculated the age at onset, duration, and intensity of overweight and obesity using linear mixed-effects models.BMI trajectories in adulthood were modeled using group-based trajectory modeling.We used Cox proportional hazards models to calculate hazard ratios (HRs) with 95% confidence intervals (Cis) for the associations between BMI exposures and breast cancer subtypes in 148,866 postmenopausal women.Advanced glycation end products (AGEs) are reactive metabolites intrinsically linked with modern dietary patterns.Processed foods, and those high in sugar, protein and fat, often contain high levels of AGEs.Increased AGE levels are associated with increased breast cancer risk, however their significance has been largely overlooked due to a lack of direct cause-and-effect relationship.Immunohistochemistry and immunofluorescence were used to assess cellular proliferation and stromal fibroblast and macrophage recruitment.The Kruskal–Wallis test were used to compare continuous outcomes among groups.Mammary epithelial cell migration and invasion in response to AGE-mediated fibroblast activation was determined in two-compartment co-culture models.In vitro experiments were performed in triplicate.The nonparametric Wilcoxon rank sum test was used to compare differences between groups.Deep learning analysis of radiological images has the potential to improve diagnostic accuracy of breast cancer, ultimately leading to better patient outcomes.This paper systematically reviewed the current literature on deep learning detection of breast cancer based on magnetic resonance imaging (MRI).The literature search was performed from 2015 to Dec 31, 2022, using Pubmed. Other database included Semantic Scholar, ACM Digital Library, Google search, Google Scholar, and pre-print depositories (such as Research Square).Articles that were not deep learning (such as texture analysis) were excluded.PRISMA guidelines for reporting were used.We analyzed different deep learning algorithms, methods of analysis, experimental design, MRI image types, types of ground truths, sample sizes, numbers of benign and malignant lesions, and performance in the literature.
Internal audit has become a vital process in the smooth and fair running of an organization as it entails a systematic and independent investigation of records, financial statements and business operations and performances. In this study, the effect of internal audit on the business organization performance in Ekiti State, Nigeria is examined. The specific objectives are to assess the independence of internal audit department and examine their level of competence. Also, the effect of size of internal audit department on the performance of business organization was evaluated. Probabilistic sampling technique was adopted and one hundred and twenty (120) copies of close-ended questionnaire were self-distributed to respondents that are either business owners or business employers in Ekiti State. Data collected were analyzed using mainly frequency counts and mean score while the stated hypotheses were tested using simple regression statistical tool via SPSS version 20.0 at 5% level of significance. The result from the study carried out showed that 83% of the total questionnaires distributed were analyzed and the analysis revealed that a positive relationship between the independent variables and the dependent variable. This mean that the internal audit process has positive effect on the performance of business organization in the study area which is statistically significant at P < 0.05. It is therefore recommended that business in the study area and beyond should ensure uncompromising engagement of internal audit process in their businesses in order to improve their performances and organization.

In this write up I explored the fast-paced nature of the African Contemporary culture acts as a catalyst for anxiety due to overstimulation. I also explored how the built environment of a retreat Centre can be designed in order to be aesthetically pleasing to the eye and bring people from a state of over-stimulation to a state of dignified calmness and composure. This paper achieved the goal of exploring the power of relaxation and helped one understand the power aesthetically pleasing architecture has in helping people lives be it thoughtful and relational. My Retreat facility was designed in such a way, that, it provided avenues by which planned meeting groups, various groups, individuals or organizations may gather together to find solution to a particular problem and problems that affects them which could be in form of lectures, seminars, debates and short courses. In This Write-up the fact that Nature over time has been overlooked and unappreciated for too long was put into consideration and I designed to proffer solution to this problem. I reintroduced the fact that Nature provides us with many benefits and is very important to our existence. Despite all these, we have failed to reciprocate any of it. My design process used initiated with a comprehensive analysis of the site and an understanding of the program required for such a project was fantastic. I made sure site-specific functions were incorporated as well into the overall programmatic layout. My design created a serene and peaceful environment where people can go for rejuvenation, relaxation, away from their normal life and daily activities. I reintroduce individuals to an experience, which states that individuals attending the retreat will be engulfed in experiencing the moment and living each breath of sensation. I explained how meditation in the lives of humans is important in contemplation, relaxation and mental hygiene and provides a platform, and serves as a vessel for self-exploration and internal growth.

Noise pollution is considered to be any unwanted or distressing sound that causes the health issues and affects the well-beings of humans and other organisms. Exposure to loud noise can also cause health hazards. The evolution of noise control and sound quality are briefly discussed. Series of research work has been done seeking to provide insights both theoretical and empirical into the problems that are related to the halls and auditoriums of conference centers, however, most of these researches seem to agree that the issue of acoustics is one of the most commonly observed challenge. Therefore the motivating factor behind this work is the desire to contribute to the improvement of acoustics in a large building such as that of a conference center. Conference center are spaces of communication and due to their size and form they often suffer from flutter echoes and room resonances. To ensure that meetings take place successfully without any itch, there is the need to have a facility that will be adequate and functional. It is therefore of paramount importance that the acoustic factors be considered and methods to mitigate the noise be implemented where necessary. To achieve success in the study, qualitative research method research as well as case studies were adopted, literatures were reviewed, and physical site observations were also made. Results from the finding revealed that the use of parallel walls in the auditorium is a major cause of echo as it causes sound waves to easily bounce back and forth over the entire room which later creates an unwanted noise and echoes that could spoil the overall sound production, the shape of the building, the size of the auditorium and materials in the room, all together play vital roles in how sound was being produced, distributed and absorbed. To solve this problem, the use of a completely squared shape should avoided for the main auditorium, the use of absorptive materials on the floor, some part of the wall and ceiling were deployed to reduce echo and reverberations.
It is believed that in the current dynamic business environment human resources is a potential source of sustained competitive advantage. Thus, creating employee job satisfaction in the workplace is a concept that should be focused while improving organizational performance. The purpose of this study is to explore the impact of employee job satisfaction on organizational performance, regarding MOJO cable and wire factory. Based on this, in this research job satisfaction is represented by five determinants, namely remuneration, working environment, supervision, promotion and teamwork. Whereas, the evaluation of the effectiveness of these independent variables practices at the mojo cable and wire factory was done through a 5-point Likert scale questionnaire. Data were collected through closed-ended structured questionnaires from the sample of 136 permanent employees through simple random method of sampling selected from the factory. However, out of 136 respondents 135 (99.26%) questionnaire was obtained valid. Consequently, Data were analyzed using descriptive and inferential statistics with the aid of Statistical Packages for Social Scientists (SPSS) version 26. However primarily Cronbach Alpha formula was used to measure the internal consistency of the questionnaire items. And, the result suggested that all the pilot variables have the crobach’s alpha value greater than 0.7 and this revealed that all the variables were reliable. Moreover, the findings from Pearson correlation articulated that there were a significant and positive relationship between each independent variables and organizational performance, and this approved that all the positive hypothesis was accepted. In addition, the result of multiple regression analysis suggested that the total correlation of all independent variable to dependent variable was 0.895. This implies there were strong and positive correlation between job satisfaction and organizational performance. In light of this, the analysis discovered remuneration was the most significant employee job satisfaction factor against the performance of mojo cable and wire factory. Therefore, it’s forwarded for the top management of the mojo cable and wire factory to improve the above variables.

Metakaolin (MK) holds promise for enhancing lateritic soil strength. The natural lateritic soil is initially classified as A4 fine silty material. MK, obtained through calcination at 700°C, is added to the soil in varying proportions (10% to 60% by dry soil weight). Unconfined compressive strength (UCS) tests are conducted under different conditions: samples conditioned for 7 days with 7 days of subsequent soaking, and unconditioned samples with a 14-day curing period. UCS exhibits improvement with rising MK content, peaking at 29.5%. Beyond this point, UCS starts to decline. For unconditioned samples, UCS increases from 224.93 kPa (10% MK) to 340 kPa (29.5% MK), and for conditioned samples, it ranges from 169.46 kPa to 270 kPa. The presence of MK results in an average 23% variation in UCS between unconditioned and conditioned samples. Regarding durability, the optimal MK content for the MK-lateritic soil combination lies within 20% to 35%, where the loss in strength remains at or below 20%. A Linear Regression Analysis establishes a predictive model for UCS at 14 days), with an R2 value of 0.926. Keywords: Metakaolin, lateritic soil, soil stabilization, unconfined compressive strength, durability, mechanical properties, calcination, soil classification, Linear Regression Analysis.
This study presents a comparative analysis of the baseline geotechnical properties and bearing capacity estimation of coastal sands in Nigeria, focusing on the Lagos and Opobo estuaries. Bearing capacity is a key parameter needed for most geotechnical/structural designs. Accurate estimation of the Bearing capacity of soft clays can be challenging to obtain in the laboratory due to the difficulty in remoulding the clay to its in-situ conditions before testing, and as a result, the bearing capacity is estimated from the shear strength and index properties. The study employs field and laboratory investigations to gather data and employs established engineering principles to estimate bearing capacities. This study was carried out at Tarkwa bay site which is located in Lagos state, and ALSCON/Opobo harbor located in Imo state, Nigeria. A total of thirty (30) boreholes were drilled and soil samples were collected at 1.5 m intervals for Tarkwa bay and Opobo harbor up to a depth of 25 m. Laboratory tests were used to obtain the moisture content, bulk unit weight, liquid and plastic limit, while CPT was used in obtaining the shear strength. Laboratory Classification of the soil samples was done by adopting the Unified Soil Classification System and statistical analysis relating the shear strength with the soil properties were developed. The result showed the soils at both sites were predominately inorganic clay of high plasticity which are problematic due to the expansion and shrinking nature of this type of soil. The descriptive analysis showed that the shear strength ranged from 18kN/m2 to 21 kN/m2 for Tarkwa bay and from 12 kN/m2 to 77 kN/m2 for Opobo harbor. The mean ultimate bearing capacity was estimated as 106.24 kN/m2 and 173.88 kN/m2 for Tarkwa bay and Opobo harbor site, respectively. This research contributes to both practical engineering knowledge and broader scientific understanding of coastal geotechnics in Nigeria, with potential applications in infrastructure development, environmental conservation, disaster risk reduction, and policy formulation. Keywords: Bearing capacity, bulk unit weight, liquid, plastic limit, shear strength
This study investigates the influence of curing time (T) on the strength evolution of cement-stabilized lateritic soil. Initial experiments were conducted to classify the untreated lateritic soil, followed by cement stabilization at varying levels of 0%, 2%, 4%, 6%, 8%, and 10% cement content (CC). Unconfined compressive strength (UCS) properties were determined using appropriate procedures after 3, 7, 14, 21, and 28 days of membrane curing. Analysis revealed the untreated lateritic soil as an A4 silty soil with a fine material content. Investigating the effect of cement content on UCS gain, a clear linear strength increase was observed for cement content up to 4%, beyond which strength gain became minimal and plateaued, declining at 10% cement addition. This indicates that the impact of cement on strength gain is significant up to around 8% cement content, beyond which diminishing returns are observed. The impact of curing duration on UCS gain indicated increasing strength from the 3rd to the 14th day of curing, followed by a reduction. Notably, interactions between modifiers and water, as well as between soil and water, significantly affected strength properties, with modifier-acid interactions exerting the least influence. This suggests that early-stage curing promotes more substantial strength gains compared to later stages. ANOVA analysis highlighted that curing duration's effect on strength increase exceeded that of percent cement addition, as evidenced by the p-values (1.12E-10 and 0.959639, respectively). A multiple regression model demonstrated a strong fit with an R2 = 0.766. Hypothesis testing using a t-statistic at a 5% significance level yielded a computed t-value (0.000191) lower than the critical t-value (t0.975,29 = 2.045). Consequently, the null hypothesis was accepted, indicating no significant difference between experimental and predicted UCS values. This study provides insights into the dynamic relationship between curing time, cement content, and strength development in cement-stabilized lateritic soils, paving the way for optimizing stabilization procedures. Keywords: Curing time, Strength development, Cement-stabilized, Lateritic soils, Experimental investigations, Untreated lateritic soil, Unconfined compressive strength (UCS), Membrane curing, Modifier-acid interaction, ANOVA analysis, Multiple regression model, Hypothesis testing, Significance, Optimize stabilization procedures.

Background/Objective: There are many different fields of human endeavours from which students can make their future career. Professionals in the field of health information management can choose from a variety of options such as health/medical, management, ethics and legal, health informatics, and health data analysis, among others. However, despite the critical roles played in the cycle of healthcare delivery, the profession is still relatively unknown and underappreciated, both locally and globally. This study therefore aims at assessing the psychological factors influencing career choice among students of School of Health Information Management OAUTHC. Method/Design: The study employed a descriptive survey design to elucidate information from the students about their Knowledge of the HIM Profession, motivational factors influencing their choice of career and their perception of the HIM Profession. A complete enumeration technique was adopted to recruit all the research participants. A total of 270 questionnaires were distributed to all 270 students of SHIM OAUTHC, and 208 were retrieved back, giving the percentage return rate of 77.04%. Results: The findings of this study revealed that the majority (84.13%) of the students had poor knowledge about health information management (HIM) profession before their admission to study the course and the majority (67.31%) had no initial plan of making HIM their first choice of career. However, the perception of the participants are both good and fair with response rates of 53.14% and 46.86% respectively. The findings also shown that the majority (57.21%) are highly motivated with their choice of HIM Profession as a career and the major factors responsible for this are the fact HIM is a healthcare profession, it helps patients and touch their lives, it offers a good education and has a brighter future prospect among others. Conclusion: Health Information Management Profession is a very important profession/Career whose impact in healthcare delivery system cannot be overemphasized. Nevertheless, the profession lack due awareness and recognition as its existence and importance is unknown to the vast majority of the public. This makes the majority of professionals go into it without having a deep knowledge of what in entails. The study therefore recommends that better awareness about the existence and importance of Health Information Management Profession should be created through various available media and potential professionals be properly guided and counseled before making a choice of career in HIM in order to get the best out of them.
The plasma membrane is made up mainly of lipids and proteins. Lipids act by ensuring the structure of the membrane, while proteins are related to the main functions performed by this cellular structure. This membrane is semipermeable in nature, being responsible for transporting and selecting molecules that enter and leave the cell. It has, as one of its functions, isolation from the surrounding environment, it is about 5 nanometers (nm) thick, and delimits the internal cellular space. The membrane has a characteristic in its structure of great importance for the maintenance of life in living beings: selective permeability. It is responsible for transporting and selecting the substances that enter and leave the cells, in addition to ensuring the elimination of components of cellular metabolism. The currently accepted model of the structure of the plasma membrane is known as fluid mosaic and was proposed by Jonathan Singer and Garth Nicolson in 1972. In this model, the plasma membrane is described as a phospholipid bilayer with the presence of proteins. The plasma membrane is a structure present in all cells, both eukaryotic and prokaryotic, and it is what separates the interior of the cells from the external environment. No wonder this envelope is present in all known cell types.

La section suivante se penche sur les défis, mettant en lumière les risques de biais et de manque de compréhension contextuelle lors de l'utilisation de l'IA dans ce contexte. De plus, les préoccupations relatives à la confidentialité et à la sécurité des données sont explorées, soulignant les points critiques à considérer lors de l'intégration de l'IA dans le domaine de la e-évaluation.
This journal article explores the enduring influence of French colonialism in former African colonies, shedding light on the various dimensions of this complex relationship. The legacies of French colonial rule continue to shape politics, economics, culture, and society in these nations. Through a comparative analysis of selected African countries, this study delves into the mechanisms and consequences of this influence, including language, trade, security, and political structures. By examining both the positive and negative aspects of French colonialism's legacy, this article provides valuable insights into the contemporary challenges and opportunities faced by these nations as they navigate their post-colonial trajectories. The study employed a mixed paradigm and descriptive survey design that sampled Institutions of higher learning, members of Parliament, Government Ministry (Judiciary) and Non-Governmental Organizations and interviewed, members of Parliament (from both ruling and opposition), senior civil servants, university lecturers, university students and NGO members. Data was obtained from respondents by means of interviews, questionnaires and project observation schedules. The sample consisted of two hundred respondents. Frequency, percentages, tables, graphs and pie-charts were used to analyze the quantitative and qualitative data obtained. Data was then analyzed manually in some cases and also, a combination of software MS Access and MS Excel. The findings revealed that the influence of French colonialism on former African colonies remains a deeply ingrained aspect of these nations' identities and trajectories though the impact varies from one country to another and across different aspects of society, but it is undeniable that the legacy of colonialism, including French colonialism, continues to shape the present and future of these African nations. and the study recommended that addressing the ongoing influence of French colonialism in former African colonies is a complex and multifaceted issue. It requires the collaboration of individuals, organizations, governments, and international bodies to foster positive change and empower African nations to shape their own destinies.
