Diversity, Distribution, and Zonation Patterns of Mangrove Species in Sulaman Lake, Tuaran, Sabah
No full textSulaman Lake is located in Tuaran-Kota Belud, Sabah is an important wetland area that supports rich mangrove ecosystems and provides resources for nearby communities. This study aimed to document and compare the diversity of mangrove species found across four zones which are Sulaman Lake, Sungai Kindu, Kampung Serusop, and Sungai Betutai. A total of 24 mangrove species were identified throughout this floral survey consisting of 12 exclusive and 12 associate mangrove species. Kampung Serusop was noted for having the greatest number of mangrove species found (18 species), followed by Sungai Betutai (19 species), Sungai Kindu (7 species), and Sulaman Lake (5 species). The Rhizophoraceae family was the most dominant and widely distributed particularly Rhizophora apiculata, R. mucronata, and Bruguiera gymnorhiza, which thrive in areas with strong tidal impact. The differences between exclusive and associate species reflected distinct zonation patterns, likely influenced by tidal changes and surrounding habitat features. All recorded species were listed as Least Concern by the IUCN. Overall, the findings highlight Sulaman Lake as a valuable and biodiverse mangrove habitat
Data-driven triage: exploring AI models for predicting emergency department outcomes
No full textIntroduction: Machine learning has become a significant trend in the healthcare sector recently, and its capabilities appear promising. This study aims to develop and validate four machine learning models in predicting triage outcomes in emergency departments.
Methodology: A retrospective cohort study utilising electronic health records in the emergency department of a teaching hospital, with four machine learning models to be evaluated: Random Forest (RF), Gradient Boosted Decision Tree (GBDT), K-Nearest Neighbors (KNN), and XGBoost.
Results: A total of 312 emergency patient records were acquired. The scores for accuracy, precision recall, and F1-score were 100% for RF, GBDT, and XGBoost. The models are also able to predict
a few classes accurately, potentially improving the triage process. Respiratory rate has a high impact on the decision in triaging to actual_class_5, which is the red zone (resuscitation), with an R-value of 0.36. Diastolic blood pressure and systolic blood pressure have a high correlation, as evidenced by the R-value, 0.61. Respiratory rate has a negative impact on oxygen saturation and a positive impact on body temperature, with R-values -0.49 and 0.32, respectively.
Discussion: On the performance tests of accuracy, precision, recall, and F1-score, the models (RF, GBDT and XGBoost) scored 100% for each of the tests, indicating a perfect classifier. This result indicates the overall ability of the model to improve triage by classifying accurately, as supported by Aljubran et al.'s (2023) statement that machine learning is a promising tool for improving triage decision-making. According to Elhaj, Achour, Tania, & Aciksari, (2023), in these performance tests the models (KNN and RF) achieved the highest score overall from 9 models trained by the researchers with an accuracy of 89.1% and 88.5%, precision of 89.0% and 88.7%, recall of 89.1% and 88.7%, and F1-score of 89.0% and 88.6%, while the CatBoost model (accuracy = 0.930, recall = 0.915, precision = 0.930, F1-score = 0.930) is clinically excellent to be developed as suggested by Aljubran et al., (2023).
Conclusion: Machine learning models can accurately triage patients when properly trained covering the possible variations of variables presented during triage. A prospective study is needed
to evaluate the models' ability further
Correlation between spinal column length and the spread of subarachnoid hyperbaric bupivacaine in the term parturient
No full textBackground: Anaesthetists frequently tailor the subarachnoid local anaesthetic dosage according to parturient height to achieve sensory blockade up to the T4 dermatome for lower segment Caesarean sections (LSCSs). Studies that have been conducted have demonstrated that height does not affect the spread of subarachnoid hyperbaric bupivacaine. This study aimed to find the correlation between the spinal column length of termparturients and the highest level of sensory blockade after spinal anaesthesia.Methods: The authors studied 60 singleton term parturients of American Society of Anesthesiologists (ASA) physical status I or II scheduled for elective LSCSs. The length of the spinal column was taken as an averageof three measurements from the C7 spinous process to the sacral hiatus in a sitting upright and facing forward position. Spinal anaesthesia was given by administering 1.8 ml of 0.5% hyperbaric bupivacaine and 25 μg fentanyl through the L3/L4 or L4/L5 intervertebral space. The level of sensory blockade was assessed using pin-prick testing for pain sensation. Linear regression analysis was used to analyse the correlation; R < 0.25 indicates no correlation with the level of significance being < 0.05.Results: The spinal column lengths measured were between 42.2 cm and 85.8 cm (median: 58.5 cm). Spinal anaesthesia given was adequate for all patients, with the highest levels of anaesthesia ranging from T8 to T2 with sensory levels between T6 and T4. The parturients’ spinal column length showed no correlation with the highest level of sensory blockade achieved, namely R = 0.11.Conclusions: The study found no correlation between the parturients’ spinal column length and the highest level of sensory blockade achieved.Keywords: spinal anaesthesia; spinal column; hyperbaric bupivacaine; parturients; lower segment Caesarean section (LSCS
METHOD OF TALAQQI MUSYAFAHAH IN TEACHING AL QURAN WA AL-HIFZ DINI CURRICULUM SABK IN PERAK
No full textThis study was conducted to identify the implementation of Talaqqi Musyafahah on teaching al-Quran in Dini Curriculum at the Perak Government Assisted Religious Schools
(SABK), to study the level of achievement in Al Quran reading and the relationship between the implementation of Talaqqi Musyafahah with the achievement of Al Quran reading of SABKs’ students. Research information was obtained through quantitative methods from questionnaires involving 304 form four SABKs’ students in Perak. The collected data was processed using the windows program of SPSS software version 22.0. The results of the study indicate that the
implementation of Talaqqi Musyafahah was high (mean=4.15, sp.= 0.65) and the achievement of al Quran reading was high (mean=4.28, sp=0.52). The study also shows that there was a
moderate high relationship (r=0.514, p <0.01) between the implementation of Talaqqi Musyafahah with the achievement of the al Quran reading. Overall, the relationship between
the implementation of Talaqqi Musyafahah with the achievement level was strong. This proved that Talaqqi Musyafahah is important in teaching and learning of al-Quran. Implications from the study show that the implementation of Talaqqi Musyafahah can enhance the achievement of reading the al Quran among the students
