    The better the literacy of the people, the better the level of thinking and the achievement of the progress of the community in various aspects of life. However, in reality our current literacy culture is still low.  Currently the partner has a side of the reading garden established in 2021 known as Fontabaca Park. But unfortunately, the establishment of a reading garden was not fully utilized by children and teenagers. This is exacerbated by the lack of reading material available in the reading garden. The lack of interest in reading or borrowing books is partly due to the lack of socialization related to literacy activities to children and adolescents in the Fontania region. The method of implementing activities starts from counseling, training, mentoring and evaluation. The results of each stage of the implementation activity start from the counseling activities carried out by analyzing the problem then continued with mapping the solutions provided for partners. Followed by providing training activities related to reading literacy and the formation of reading garden cadres. Mentoring activities are in the form of procurement of needed reading book materials and involving participants to label and collect reading books. Evaluation activities obtained an average percentage of 98% of the impact of activities carried out by the implementation team as an effort to optimize the existing Fontabaca park.The better the literacy of the people, the better the level of thinking and the achievement of the progress of the community in various aspects of life.

    Utilizing Random Forest with iForest-based outlier detection and SMOTE to detect movement and direction of RFID tags

    Get PDF
    In recent years, radio frequency identification (RFID) technology has been utilized to monitor product movements within a supply chain in real time. By utilizing RFID technology, the products can be tracked automatically in real-time. However, the RFID cannot detect the movement and direction of the tag. This study investigates the performance of machine learning (ML) algorithms to detect the movement and direction of passive RFID tags. The dataset utilized in this study was created by considering a variety of conceivable tag motions and directions that may occur in actual warehouse settings, such as going inside and out of the gate, moving close to the gate, turning around, and static tags. The statistical features are derived from the received signal strength (RSS) and the timestamp of tags. Our proposed model combined Isolation Forest (iForest) outlier detection, Synthetic Minority Over Sampling Technique (SMOTE) and Random Forest (RF) has shown the highest accuracy up to 94.251% as compared to other ML models in detecting the movement and direction of RFID tags. In addition, we demonstrated the proposed classification model could be applied to a web-based monitoring system, so that tagged products that move in or out through a gate can be correctly identified. This study is expected to improve the RFID gate on detecting the status of products (being received or delivered) automatically.Web of Science153art. no. 10

    Get PDF
    Background: Several studies have revealed the potential use of tocilizumab in treating COVID-19 since no therapy has yet been approved for COVID-19 pneumonia. Tocilizumab may provide clinical benefits for cytokine release syndrome in COVID-19 patients. Methods: We searched for relevant studies in PubMed, Embase, Medline, and Cochrane published from March to October 2020 to evaluate optimal use and baseline criteria for administration of tocilizumab in severe and critically ill COVID-19 patients. Research involving patients with confirmed SARS-CoV-2 infection, treated with tocilizumab and compared with the standard of care (SOC) was included in this study. We conducted a systematic review to find data about the risks and benefits of tocilizumab and outcomes from different baseline criteria for administration of tocilizumab as a treatment for severe and critically ill COVID-19 patients. Results: A total of 26 studies, consisting of 23 retrospective studies, one prospective study, and two randomised controlled trials with 2112 patients enrolled in the tocilizumab group and 6160 patients in the SOC group, were included in this meta-analysis. Compared to the SOC, tocilizumab showed benefits for all-cause mortality events and a shorter time until death after first intervention but showed no difference in hospital length of stay. Upon subgroup analysis, tocilizumab showed fewer all-cause mortality events when CRP level ≥100 mg/L, P/F ratio 200-300 mmHg, and P/F ratio <200 mmHg. However, tocilizumab showed a longer length of stay when CRP <100 mg/L than the SOC. Conclusion: This meta-analysis demonstrated that tocilizumab has a positive effect on all-cause mortality. It should be cautiously administrated for optimal results and tailored to the patient's eligibility criteria

    Background: Management of systemic lupus erythematosus (SLE) and lupus nephritis (LN) in pregnancy has been improving in recent decades. However, SLE can still lead to adverse pregnancy outcomes if not appropriately treated. Optimal dose of steroids, as one of the most commonly used for the treatment of SLE and LN in pregnancy is still a subject of debate. In this review, we determine the pregnancy outcomes in SLE and LN patients treated with low vs high doses of steroids. Methods: ProQuest, Pubmed, Science Direct, Scopus, and Web of Science were carefully searched for relevant studies published in English. A total of 2,596 studies were reviewed. We extracted the data from previous studies showing the use of steroids treatment in high-dose and low-dose related to pregnancy outcomes. We provide larger data about maternal (preterm rupture of membrane, fetal loss, pre-eclampsia, and flare up) and fetal outcomes (prematurity, small gestational age, low birth weight) receiving high vs low steroid in patients with SLE and LN in this systematic review and meta-analysis. Results: A total of 13 studies were included. Of these, one study discussed a group with LN and 12 other studies discussed SLE with related maternal and fetal outcomes. Maternal outcome in the group with low-dose steroid showed a lower risk of fetal loss (odds ratio (OR): 1.93; 95% confidence interval (CI) 1.01-3.70), but there were no differences in other maternal outcomes. The low-dose steroid group showed a better fetal outcome, with a lower risk of prematurity (OR: 3.06; 95% CI 1.98-4.71), small gestational age (OR: 2.63; 95% CI 1.15-6.00), and low birth weight (OR: 2.43; 95% CI 1.23-4.79). Conclusions: In pregnant patients with SLE or LN, high-dose steroids are associated with the high risk of fetal loss during pregnancy, preterm birth, small gestational age, and low birth weight

    Propolis contains a wide range of pharmacological activities because of their various bioactive compounds. The beneficial effect of propolis is interesting for treating type-2 diabetes mellitus (T2DM) owing to dysregulation of multiple metabolic processes. In this study, 275 of 658 Asian propolis compounds were evaluated as potential anti-T2DM agents using the DIA-DB web server towards 18 known anti-diabetes protein targets. More than 20% of all compounds could bind to more than five diabetes targets with high binding affinity (&lt;&minus;9.0 kcal/mol). Filtering with physicochemical and pharmacokinetic properties, including ADMET parameters, 12 compounds were identified as potential anti-T2DM with favorable ADMET properties. Six of those compounds, (2R)-7,4&prime;-dihydroxy-5-methoxy-8-methylflavone; (RR)-(+)-3&prime;-senecioylkhellactone; 2&prime;,4&prime;,6&prime;-trihydroxy chalcone; alpinetin; pinobanksin-3-O-butyrate; and pinocembrin-5-methyl ether were first reported as anti-T2DM agents. We identified the significant T2DM targets of Asian propolis, namely retinol-binding protein-4 (RBP4) and aldose reductase (AKR1B1) that have important roles in insulin sensitivity and diabetes complication, respectively. Molecular dynamic simulations showed stable interaction of selected propolis compounds in the active site of RBP4 and AKR1B1. These findings suggest that Asian propolis compound may be effective for treatment of T2DM by targeting RBP4 and AKR1B1

    ABSTRACT Excessive release of interleukin-6 (IL-6) during the progression of coronavirus disease 2019 (COVID-19) induces cytokine storms, resulting in multi-organ damages including liver injury, similar in nature with mechanism of viral hepatitis. Systemic IL-6 has been associated with the incidence of liver injury among COVID-19 patients; however, studies on IL-6 expression in the liver tissue are completely lacking. The aim of this study was to measure the IL-6 expression in the liver tissues and to determine its correlation with the degree of liver injury in fatal COVID-19 patients. Through this first cross-sectional study, IL-6 expression was measured through immunohistochemical staining and the degree of liver injury was identified based on level of serum alanine aminotransferase (ALT). The Spearman correlation test was used to identify the correlation between IL-6 expression and the degree of liver injury. A total of 47 deceased COVID-19 patients were included and IL-6 expression was observed in all post-mortem liver specimens, ranging from mild to strong expression. Liver injury at various degrees (mild to severe) was found in more than half (59.5%) of the cases. The Spearman correlation analysis suggested a statistically insignificant correlation between liver IL-6 expression and the degree of liver injury (r=0.152; p=0.309). In conclusion, even IL-6 expression was observed in all post-mortem liver specimens, there was an insignificant correlation between IL-6 expression in the liver tissue with the degree of liver injury among fatal COVID-19 patients, suggesting that IL-6 was not the only main factor contributing to liver damage in COVID-19 patients
