Aeromagnetic data over the Mamfe Basin have been processed. A regional magnetic gridded dataset was obtained from the Total Magnetic Intensity (TMI) data grid using a 3 × 3 convolution (Hanning) filter to remove regional trends. Major similarities in magnetic field orientation and intensities were observed at identical locations on both the regional and TMI data grids. From the regional and TMI gridded datasets, the residual dataset was generated which represents the very shallow geological features of the basin. Processing this residual data grid using the Source Parameter Imaging (SPI) for magnetic depth suggests that the estimated depths to magnetic sources in the basin range from about 271 m to 3552 m. The highest depths are located in two main locations somewhere around the central portion of the study area which correspond to the area with positive magnetic susceptibilities, as well as the areas extending outwards across the eastern boundary of the study area. Shallow magnetic depths are prominent towards the NW portion of the basin and also correspond to areas of negative magnetic susceptibilities. The basin generally exhibits a variation in depth of magnetic sources with high, average and shallow depths. The presence of intrusive igneous rocks was also observed in this basin. This characteristic is a pointer to the existence of geologic resources of interest for exploration in the basin.

The Automated Actuarial Pricing and Underwriting Model has been enhanced and expanded through the implementation of Artificial Intelligence to automate three distinct actuarial functions: loss reserving, pricing, and underwriting. This model utilizes data analytics based on Artificial Intelligence to merge microfinance and car insurance services. Introducing and applying a no-claims bonus rate system, comprising base rates, variable rates, and final rates, to three key policyholder categories significantly reduces the occurrence and impact of claims while encouraging increased premium payments. We have enhanced frequency-severity models with eight machine learning algorithms and adjusted the Automated Actuarial Pricing and Underwriting Model for inflation, resulting in outstanding performance. Among the machine learning models utilized, the random Forest (rANGEr) achieved the highest Total Aggregate Comprehensive Automated Actuarial Loss reserve risk Pricing Balance (ACAALrrPB), establishing itself as the preferred model for developing Automated Actuarial Underwriting models tailored to specific policyholder categories.

Background: Treatment non-adherence poses significant risks to health outcomes and impedes the health system’s efficiency, hence curtailing progress towards the end Tuberculosis (TB) strategy under SDG 3.3. Despite interventions to address TB treatment non-adherence, Kenya still reports high TB treatment non-adherence rates of 35% and consequently poor treatment outcome rates. Health Care Workers (HCWs) play a critical role in linking the population to health services, yet little is known of their influence on patients’ TB treatment non-adherence in Kenya. Objective: To analyze HCW-related factors associated with TB treatment non-adherence among patients in Kisumu East Sub-County. Methods: Health facility-based analytical cross-sectional mixed-method study. A Semi-structured questionnaire on treatment adherence and patients’ perceptions of HCWs during the clinic visit was administered to 102 consenting adult (out of a total census of 107 adults) drug-susceptible TB patients. 12 purposively selected HCWs by rank from 6 health facilities participated in Key Informant Interview sessions. Medication adherence was measured using the Morisky Medication Adherence Scale and then expressed as a dichotomous variable. Quantitative analysis utilized STATA version 15.1 while qualitative deductive thematic analysis was done using NVIVO version 14. results: TB treatment non-adherence rate of 26% (CI: 18% - 36%) was recorded. Overall, patients who felt supported in dealing with the illness were 8 times more likely to adhere to treatment compared to those who were not (aOr = 7.947, 95% CI: 2.214 - 28.527, p = 0.001). Key HCW related factors influencing adherence to treatment included: friendliness (cOr = 4.31, 95% CI: 1.514 - 12.284, p = 0.006), respect (cOr = 6.679, 95% CI: 2.239 - 19.923, p = 0.001) and non-discriminatory service (cOr = 0.1478, 95% CI: 0.047 - 0.464, p = 0.001), communication [adequacy of consultation time (cOr = 6.563, 95% CI: 2.467 - 17.458, p = 0.001) and patie

The Unintentional Insider Threat (UIT) concept highlights that insider threats might not always stem from malicious intent and can occur across various domains. This research examines how individuals with medical or psychological issues might unintentionally become insider threats due to their perception of being targeted. Insights from the survey A Survey of Unintentional Medical Insider Threat Category indicate that such perceptions can be linked to underlying health conditions. The study Emotion Analysis Based on Belief of Targeted Individual Supporting Insider Threat Detection reveals that anger is a common emotion among these individuals. The findings suggest that UITs are often linked to medical or psychological issues, with anger being prevalent. To mitigate these risks, it is recommended that Insider Threat programs integrate expertise from medicine, psychology, and cybersecurity. Additionally, handwriting analysis is proposed as a potential tool for detecting insider threats, reflecting the evolving nature of threat assessment methodologies.

Introduction: Technological advances have greatly influenced the healthcare sector. The ability to transmit information and deliver services using telecommunication tools continues to transform the way healthcare is delivered around the world. The aim of this study was to highlight the epidemiological, clinical and therapeutic profile of oral and maxillofacial surgery patients consulted using the WhatsApp application. Methodology: This was a three-year descriptive study with a retrospective data collection, from 2021 to 2023, of WhatsApp communications between our team and oral and maxillofacial surgeons in Cameroon. In this study, the type/content of messages received, the epidemiological data of practitioners and patients, the various pathologies diagnosed and the procedures performed were evaluated. results: 319 communications were received for a total of 146 cases. Written messages associated with images (photographs and/or X-rays) were the most frequently received, at 85.62%. Hospitals in urban areas were the most represented at 93.84%. Oral health professionals in the private sector sent more messages (65.75%). In terms of diagnoses, tumour and cystic pathologies were the most common (28.08%), followed by impacted/retained teeth (22.6%). Patients were referred to our hospital for treatment in 62.33% of cases. Conclusion: The WhatsApp application is an easy-to-use telecommunications tool. It facilitates exchanges between practitioners and improves patient care in oral and maxillofacial surgery.

目的:通过使用无目标不加权及目标加权的复杂网络模型方法,分析睡眠障碍运动员睡前神经机能状态与睡眠质量的复杂作用方式,揭示运动员发生睡眠障碍的神经机能状态特征。方法:在睡眠实验室内使用多导睡眠仪监测14名男性睡眠障碍运动员4晚完整睡眠,并在睡前使用便携式脑电仪、超慢波涨落潮技术、Polar H10心率胸带和心境状态量表,分别测试或评估中枢机能状态、脑内神经递质水平、自主神经状态以及情绪状态。基于测试数据分别建立无目标不加权,以及以睡眠质量为目标的加权复杂网络模型。结果:1)无目标不加权的复杂网络模型中,介数中心性结果提示,慌乱、精力和愤怒情绪、α抑制%、去甲肾上腺素(NE)和多巴胺、相邻窦性r-r间期差值大于50 ms所占百分比(PNN50)、平均r-r间隔、平均心率(MHr)和睡眠总时间是此网络的关键影响节点。特征向量中心性分析结果显示,上述指标中除PNN50、NE和MHr外,抑郁、紧张和疲劳情绪与其他指标仍是网络的重要连接节点。2)在以睡眠质量为目标的加权复杂网络模型中,目标介数中心性结果发现,情绪状态在到达睡眠质量指标的最短路径中出现频率最高(48.57%),其次神经递质和睡眠指标频率相同(14.29%),而中枢神经机能状态和自主神经状态出现的频率最低(11.43%)。目标特征向量中心性结果表明,情绪状态成为影响睡眠质量最重要的影响因素,出现频率为82.86%,其次是自主神经状态出现频率为8.57%,而中枢神经机能状态、神经递质和睡眠指标出现频率相同(2.86%)。结论:运动员睡眠障碍的主要表现为总时长短,睡眠期间觉醒时间长导致睡眠效率低。复杂网络模型方法揭示了情绪(主要为消极情绪)是睡眠质量低和睡眠障碍发生的主要影响节点和关键因素,其中愤怒、慌乱情绪与脑内神经递质(5-HT和DA)、中枢疲劳程度相关,中枢疲劳程度和自主神经协调性与精力状态相关。
