Published: September 2024

The purpose of this study was to investigate the challenges Teachers face in Implementing Eclectic Approach for students’ English-speaking skills. Case study of Two secondary schools in Rwanda. Two specific objectives guided this study: To identify the challenges and suggest sustainable solutions to the challenges. The study was guided by Learning by Doing Theory by Dewey to encourage people to learn any new concept through the practice and it matches with the solution to the challenges that they may face when exercising an Eclectic approach in teaching and learning process. Qualitative research design was used in this study. The data were collected using interviews for English teachers and directors of studies and classroom observation. The total targeted population was14 of 12 English teachers and 2 directors of studies from the schools under the study. The sample size was 11 English teachers sampled through table of Risk-Based formula. The data was analysed through a thematic technique. The findings exposed that lack of knowledge about the approach, inability to integrate all four languages together. The respondents have proposed some sustainable solutions such as participation in-service trainings about the approach, provision of free time for teachers to plan their lessons together, love of work culture. The researchers drew some conclusions such as challenges still exist and teachers have to change their mindset to help students learn English by incorporating all the language skills and be supported regarding their individual differences. The researchers recommend English teachers to learn by doing and they will be able to apply the eclectic approach towards the students’ English language skills.

Background Fentanyl is a powerful opioid. The abuse and overdoses related to Illicitly Manufactured Fentanyl (IMF) have become more prevalent. The majority of clinical studies on fentanyl have focused on its medical and biological aspects, particularly its addictive properties. Few studies have delved into the psychological aspects of illicit fentanyl use, and there is currently no comprehensive review providing a structured psycho-social profile of the population groups most vulnerable to its effects. The goal of this Scoping Review was to construct a psychological and social profile of individuals at risk of using illicit fentanyl. This profile will serve as a guiding force for shaping behavioral policies and public health prevention efforts necessary to face the recent pandemic. Methods Following the PRISMA guidelines we conducted a Scoping Review focused on the following research question: What are the practical psycho-social implications of illicit fentanyl use in the global population? Results The bibliographic research was carried out in the databases of Medline, Scopus, and PsycNet. The articles resulting from the research phase in the databases listed above produced a total of 17737 reports. After the screening process, 10 studies were included in the scoping review. Discussion and Conclusion This scoping review was the first to consistently and systematically outline the psychosocial implications of fentanyl dependence. Users of IMF are consistently younger than other drug users. People using fentanyl have a relatively low perception of risk. On the psycho-social levels, there is a significant correlation between fentanyl use and mental disorders such as suicidal thoughts, anxiety disorders, and depression. The development of psychotherapy, along with digital tools such as apps and online platforms, can be an initial step in addressing this challenge.

Study design Systematic review Background Conservative treatment is clinically preferred for lumbar disc herniation (LDH), and surgery is considered when patients’ life quality is still affected by LDH symptoms after three months’ conservative treatment. Spontaneous resorption of nucleus pulposus (NP) is common during conservative treatment. However, the current understanding for the mechanism of NP spontaneous resorption is lacking. Purpose The aim of this study was to elucidate the rate of NP spontaneous resorption, the evidence of predicting spontaneous resorption, and the pathophysiologic mechanisms of spontaneous resorption in the conservative management of LDH based on existing evidence from literature. Methods Studies related to NP spontaneous resorption of LDH were retried from PubMed, Embase, and Cochrane databases. Based on the studies conforming to inclusion criteria, a systematic review was generated for describing the proportion of NP spontaneous resorption, evidence of predicted resorption, and pathophysiologic mechanisms of spontaneous resorption. Results We reviewed a total of 34 articles dealing with the percentage of LDH resorption. The percentage of NP spontaneous resorption after conservative treatment was 76.6% (1684/2199), ranging from 20% to 96.2%. A total of 25 papers were reviewed, involving evidence of predicting resorption using predictors including NP size, inflammatory response to NP herniation, NP prolapse, the percentages edge-enhancing area and posterior longitudinal ligament coverage of the herniation measured by enhanced MRI. Moreover, we analyzed a total of 22 papers describing the pathophysiologic mechanisms of NP spontaneous resorption, where main mechanisms include inflammatory response, neovascular growth, macrophage infiltration, immune intervention, and matrix degradation. Conclusions A percentage of 76.6% in LDH patients undergo NP resorption. Prolapsed NP has a greater contact surface with blood system, which is easily to trigger immune response and thus promote spontaneous resorption. The mechanism of NP spontaneous resorption is mainly due to macrophage infiltration leading to immune response.

BACKGROUND Among all MBD cases, 3% have an unidentified origin and are commonly misdiagnosed. On average, nearly 75% of MBD cases with an unknown origin take four months to diagnose. This difficulty in identifying the primary cancer limits the treatment of skeletal metastases to palliative measures, negatively impacting a patient’s prognosis. The purpose of this systematic review is to evaluate the current diagnostic work-up approaches available for MBD. METHODS This systematic review was carried out according to the guidelines of the (PRISMA) 2020 Statement, including studies with a population of interest of MBD with unknown primary origin. We excluded studies with non-English language and MBD cases with known origin. The intervention of the diagnostic approach was the primary outcome. The authors searched three electronic medical databases. Individual reviewers performed quality and risk of bias assessments. RESULTS All ten articles were cohort studies, with the median age of the subjects ranging from 55.6 to 65.2 years. The most frequently recommended supporting examination was biopsy, with a detection rate of 38.2%, followed by chest X-ray and CT scan, both with a detection rate of 26.7%. Overall, the detection rate of the primary lesion from individual examinations ranged from 2.8% to 38.2%, highlighting the difficulty of diagnosis when relying solely on a single examination. CONCLUSIONS Biopsy is crucial in identifying the primary lesion of metastatic bone disease with an unknown origin, with a detection rate of 38.2%, making it the most frequently recommended examination. However, this review has several limitations. A few assumptions were made in the synthesis of numerical data.

Bisphenol-A is a standard monomer used in manufacturing plastics and epoxy resins, and it is widely used in food preservation and packaging. It is an endocrine-disrupting chemical miming the endogenous estradiol hormone. Melatonin regulates sleep-wake cycles and plays essential physiological roles in the body through its antioxidative properties. This research aims to ascertain the impact of Bisphenol A on the hypothalamic-pituitary-ovarian axis and determine melatonin's function on possible BPA-induced effects. Six adult male Wistar rats and 12 adult female Wistar rats of proven fertility were bred and organized into groups. These animals were subjected to subcutaneous injections of high and low doses of bisphenol A from postnatal days 0-3, then oral melatonin. The rats were allowed to mature into full-grown adults and euthanized at 120 ±4 days. The serum and hypothalamic-pituitary-ovarian tissues were collected for various assays. Compared to the control groups, groups administered varying doses of bisphenol A showed significant overexpression of estrogen and androgen receptors. Administration of Melatonin showed some reversal and reparative effects on damage of the hypothalamic pituitary ovarian axis. Elevated estrogen receptor levels induced by Bisphenol A altered receptor function. Melatonin showed some promising reparative effects.

Machine learning algorithms are utilized in various practical applications and academic research. Due to the advent of digital technology, there is now a greater availability of massive, organized, and georeferenced datasets. This has simplified the use of algorithms for trend analysis and detection as well as forecasting, which helps users make decisions. The purpose of this study is to determine which Machine Learning (ML) algorithms are most effective in projecting housing price and to assess how the COVID-19 has affected these prices. The method includes the stages of data preprocessing, feature manipulation, hyperparameter tuning, evaluation, selection, and, in the end, interpretation of the model. Another objective is to assess and compare several ensemble learning strategies, comprising bagging techniques like random forest, and boosting techniques like Gradient Boosting Regressor, using a linear regression model. The results of this study confirm that the real estate sector is very resistant to pandemics, as the decline in prices was not as severe as initially anticipated. Among the several models that were examined, extreme gradient boosting demonstrated the highest level of accuracy, albeit with a minimal difference.

ABSTRACT: Scheduling is an information medium used to facilitate the timing of the implementation of activities. As well as the implementation of the practicum at the Faculty of Information Technology, Bale Bandung University which determines the schedule using a scheduling application. However, in this practicum scheduling application, you can still input the same data and of course this can cause the practicum schedule to conflict. So to avoid the similarity of the practicum schedule data, it must be checked again manually. This practicum scheduling application needs to be developed again so that the implementation of the practicum will be helped more easily and practically. The development of this practicum scheduling application uses genetic algorithms to avoid the same data and recommend non- conflicting schedules. In the process of developing the application, practicum scheduling is carried out using the System Development Life Cycle (SDLC) waterfall model method with stages of analysis, design, implementation and testing. In addition to scheduling avoiding conflicts and displaying schedule recommendations using genetic algorithms plus also by using the add, edit and delete features multiple in one action to make it easier for users to process data, especially practical data, because every year they have to input practices or new students.

Authors: Zubkov Oleksandr , Torchynskyi Victor 
Published: September 2024

Introduction: A common complication after hip arthroplasty is pain and inflammation in other large joints, especially the knee joint. Displacement of the centre of rotation of the femoral head after endoprosthetics can change the redistribution of force vectors acting on the femur, change its tilt and pressure on the surface of the knee joint. Objective: The investigation of the effect of displacement of the centre of rotation of the hip joint after arthroplasty on the knee joint.Methods: Using SolidWorks software and the SimulationXpress tool, a 3D model of the lower limb was created that reproduced the interaction between the components of the musculoskeletal system.Results: As a result, it was found that the displacement of the centre of rotation of the hip joint medially and laterally from the anatomical position leads to a significant increase in pressure on the corresponding tibial condyles. The increase in load is linear and increases from a minimum value of 1.77 N⋅m in anatomical position to 123.79 N⋅m with a medial displacement of up to 8 mm.Conclusions: This study indicates the need for proper restoration of the centre of rotation of the hip joint after implantation and the possible consequences of changes in knee joint loads. The data may be useful for specialists working in the field of implantology and the development of hip prosthesis systems

In the present study, a checklist of butterflies from the Ananda Tea Estate of Lakhimpur district, Assam is prepared and presented. During the study, surveys were carried out from October 2022 to April 2024 in the Ananda tea estate (27°27' N and 94°14' E) and its nearby areas– Dulung reserve forest and Subansiri river. A total of 36 species across 32 genera belonging to five families viz., Nymphalidae, Pieridae, Papilionidae, Lycaenidae, Riodinidae were recorded during the study. Amongst all the families, Nymphalidae was the most diverse family comprising 17 species which belong to 16 different genera. Approximately 48% of the recorded species belong to the Nymphalidae family, indicating the highest species richness. The dominant nature of the family Nymphalidae can be attributed to the polyphagous nature of the species under the family which help them to live in diverse habitats. The species Common albatross (Appias albina), recorded during the study, is protected under Schedule II of the Wildlife (Protection) Amendment Act, 2022 of India. The Whittaker β-diversity was found to be 0.6875, indicating a moderate level of species turnover among the study sites. In the tea estate, due to the spraying of chemical pesticides large number of butterflies die each year which can be saved by replacing the chemical pesticides with biopesticides and other eco-friendly pest control methods including use of botanicals, Indigenous Technical Knowledge (ITKs) and microbial antagonists.
