Abstract: A qualitative descriptive study was used for the process of internalizing palawija farmers to watermelon farmers in Wotgalih village, Yosowilangun sub-district, Lumajang regency. Based on the existing phenomena, the impact arising from the internalization process can be seen from the realm of economic education, especially non-formal education. Data and data sources were collected based on observations and interviews with several informants who lived in the Wotgalih Yosowilangun area. The results of the analysis of data collected from the management and members of the Margo Tani group are twofold: first, the process of internalization of palawija farmers and watermelon farmers together through three things, namely learning while working, learning by word of mouth and learning while practicing. The difference is among the three of them on palawija farmers, that is, palawija farmers' profession is obtained from generation to generation from the family. Unlike the farming of watermelons obtained through these three things without having to pay personal expenses. Second, the Impact of Internalization of Economic Education in the "Margo Tani" Watermelon Farmer Group in the village of Wotgalih brought the price of rent and the selling price of land to rise. The income of the watermelon farmers has increased and is living a prosperous life and the local village is well-built and neat.

Published: September 2021

Los sistemas de comunicación entre nodos sensores y los equipos de búsqueda y rescate presentan posibles vulnerabilidades ante emergencias o catástrofes, como el fallo de la infraestructura del sistema o la saturación de la red. Por ello, es necesario evaluar alternativas para garantizar la disponibilidad del sistema y los datos necesarios para la estrategia del equipo. Los requerimientos de una red de largo alcance y bajo consumo apuntan a evaluar las distintas tecnologías que engloban las redes LPWAN (Low Power, Wide Area Network). Entre ellas, destaca el protocolo LoRaWAN (Long Range, Wide Area Network) por ofrecer una flexibilidad operativa que no tienen los demás. De lado del hardware, se realizó una selección de componentes abiertos para los nodos sensores y el gateway. Para conseguir una red ad-hoc se ha usado el proyecto ChirpStack como servidor de red y de aplicación. Finalmente, se ha integrado el software de aplicación QGIS con la base de datos PostgreSQL que almacena los datos en la misma tarjeta host del gateway. El sistema fue probado en las XV Jornadas Internacionales de la Universidad de Málaga sobre Seguridad, Emergencias y Catástrofes.

How Do Disruptive Innovators Prepare Today's Students to Be Tomorrow's Workforce?: Minerva's Co-op Model: A Pathway to Closing the Skills Gap
Authors: Goldemberg Diana , Genone James , Wisor Scott
Published: September 2021

Bridging the skills gap is necessary to increase productivity and equity. In Latin America and the Caribbean, this challenge has manifested in high rates of youth unemployment, informality, and inactivity. Traditional higher education has struggled to respond to this challenge, with rising costs limiting access and poor outcomes forcing students to question the value of a university degree. In this paper, we explore a model for collaboration between higher education providers and employers designed to overcome these challenges. In this co-op model, students earn a bachelors degree in three years, while also working part-time during the second and third years. This model provides students with the foundational skills and knowledge needed to become broad, interdisciplinary thinkers, while also giving them valuable work experience for which they earn credit while pursuing their degree. Economic constraints are addressed by students degrees being partly subsidized by an employer, who benefits by easily hiring employees who can fill their most critical human resource needs.
Position and Speed Estimation of PMSM Based on Extended Kalman Filter Tuned by Biogeography-Based-Optimization
Authors: Allaoui Samia , Laamari Yahia , Chafaa Kheireddine , Saad Salah
Published: September 2021

In a sensorless control of PMSM based on Extended Kalman Filter (EKF), the correct selection of system and measurement noise covariance has a great influence on the estimation performances of the filter. In fact, it is extremely difficult to find their optimal values by trial and error method. Therefore, the main contribution of this work is to prove the efficiency of Biogeography-Based-Optimization (BBO) technique to obtain the optimal noise covariance matrices Q and R. The BBO and EKF combination gives a BBO-EKF algorithm, which allows to estimate all the state variables of PMSM drive particularly, the rotor position and speed. In this paper, three evolutionary algorithms namely Particle Swarm Optimization (PSO), genetic algorithms (GAs) and BBO are used to get the best Q and R of EKF. Simulations tests performed in Matlab Simulink environment show excellent performance of BBO-EKF compared to GAs-EKF and PSO-EKF approaches either in resolution or in convergence speed.
Preferences based interventions to address the use of antibiotics without prescription: a discrete choice experiment
Authors: Aponte-González Johanna , Brown Paul , Eslava-Schmalbach Javier
Published: September 2021

Background: In many countries, concerns have arisen over the population using antibiotics without consulting a physician. This practice can place patients at risk and increase antibiotic resistance in the community.

Objective: To evaluate individuals' preferences regarding the use of antibiotics. The study also assessed the likely effectiveness of interventions aimed at reducing inappropriate use of antibiotics.

Methods: A discrete choice experiment (DCE) was conducted in Bogotá, Colombia. The attributes were determined by a systematic literature review and four focus group sessions. The DCE included nine factors – cost, time to get attention, level of symptoms, efficacy, safety, among others- and one label -using or not antibiotics. Data analysis was carried out using a generalized multinomial logit (GMNL) model. Marginal probabilities of different sets of attributes' levels were compared to estimate the likely effectiveness of interventions.

Results: The survey was administered to 222 participants from diverse socioeconomic backgrounds. The results suggest that participants preferred not taking antibiotics and having a physician as an advisor, but the probability of inappropriate antibiotic use increased as the waiting time or the cost of receiving advice rose. The pharmacy was the preferred source of antibiotics, and participants chose the pharmacy worker (nonprofessional) as an advisor over the nurse on the phone. In the absence of any interventions aimed at reducing the use of antibiotics, approximately 47.3% of people would misuse antibiotics. This reduces to 26.5% when people perceive the efficacy of the antibiotics as low and the potential risks of self-medicating as high. An alternative model using a nursing service would likely lower inappropriate use of antibiotics.

Conclusions: Even though people prefer not using antibiotics or visiting a physician in case of disease rather than self-medicating, current access conditions might discourage them from appropriately use antibiotics. The results suggest that interventions that informing people about the risks of self-medication and the low efficacy might significantly reduce inappropriate use of antibiotics. Our results also suggest that programs that empower other health professionals to provide access to antibiotics would likely further lower inappropriate use.

Published: September 2021

BACKGROUND: Psoriasis is an autoimmune disease involving genetic-environmental factors. Human Leukocyte Antigen (HLA)-Cw6 allele is the main genetic risk factor of psoriasis, but its prevalence varies widely. HLA-Cw6 allele correlates with psoriasis clinical type and treatment responses. Narrowband ultraviolet B (NB-UVB) and methotrexate (MTX) are effective psoriasis treatments but their association with HLA-Cw6 allele has not been identified. The study aims to determine the association between HLA-Cw6 allele expression, NB-UVB, and MTX treatment responses in Javanese-Indonesian psoriasis subjects.METHODS: Ninety Javanese-Indonesian psoriasis subjects were recruited in this study, 45 subjects were treated using NB UVB, while the other 45 subjects were treated using MTX, respectively, for 12 weeks. The psoriasis diagnosis and treatment responses were evaluated by dermatologists using Psoriasis Area Severity Index (PASI) score. The HLA-Cw6 allele was examined using the single-specific-primer polymerase chain reaction method. Fisher's Exact and Chi-square tests were employed, where p-value<0.05 was considered of significant association.RESULTS: The HLA-Cw6 allele positivity was identified in 23 psoriasis subjects (25.56%), while the other 67 subjects expressed HLA-Cw6 allele negative (74.44%). Female with HLA-Cw6 allele positivity who did not have comorbid disease show good response to NB-UVB than MTX. Meanwhile, subjects who were treated with MTX showed no association between therapeutic response and HLA-Cw6. HLA-Cw6 status was not correlated with the onset of psoriasis, family history, and comorbid diseases in all subjects.CONCLUSION: HLA-Cw6 allele expression is more associated with good NB-UVB treatment response than with MTX treatment response in female Javanese-Indonesian psoriasis subjects without comorbid disease.KEYWORDS: HLA-Cw6, narrowband ultraviolet B, methotrexate, Javanese, psoriasis

BACKGROUND: Hyaluronic acid (HA) is an essential component of extracellular matrix and mediates signaling in wound healing. HA could induce growth factor release from Advanced Platelet Rich Fibrin (A-PRF), including Vascular Endothelial Growth Factor (VEGF) and Platelet-derived Growth Factor (PDGF). However, concentrations of the released-VEGF and PDGF have not been clearly disclosed. Therefore, current study was conducted to measure the release of these growth factors in HA + A-PRF gel of diabetic foot ulcer (DFU) subjects.METHODS: Twenty DFU subjects were included in the study and treated with A-PRF or HA+A-PRF. A-PRF was derived from autologous peripheral blood and processed with low-speed centrifugation. HA was added with a ratio of 1:0.6. A-PRF or HA + A-PRF was applied topically on DFU. Upper tips of A-PRF or HA + A-PRF gels were collected on day 0, 3 and 7 for measurements of VEGF and PDGF concentrations with Enzyme-linked Immune-sorbent Assay (ELISA) methods.RESULTS: On day-3, both VEGF and PDGF concentrations of HA + A-PRF group were significantly higher than the VEGF (p=0.000) and PDGF (p=0.019) concentrations of A-PRF group. The VEGF and PDGF concentrations were continuously and significantly increased on day-7 of HA + A-PRF group, compared to the VEGF (p=0.000) and PDGF (p=0.004) concentrations of A-PRF group.CONCLUSION: Combination HA+A-PRF induces VEGF and PDGF release from A-PRF. A mixture of A-PRF and HA could be more effective than A-PRF alone for treatment of DFU.KEYWORDS: hyaluronic acid, advanced platelet rich fibrin, PRF, growth factor, VEGF, PDGF, diabetic foot ulcer

BACKGROUND: Colon cancer is still a crucial concern in the development of chemotherapeutic drugs due to the drug resistance phenomenon and various side effects to patients. One of the newest compound that show anticancer activities against several cancer cells, Chemoprevention Curcumin Analog 1 (CCA-1.1), has increasingly been explored to overcome the limitation of conventional drugs.METHODS: We evaluated the anti-migratory effect of CCA-1.1 and Pentagamavunone-1 (PGV-1) by using WiDr colon cancer cells. The expression profiles of Tumor Protein 53 (TP53) and Matrix Metalloproteinase-9 (MMP9) in colon cancer were obtained from the UALCAN database. Survival outcomes of TP53 and MMP9 in colon cancer patients were analyzed using the Kaplan-Meier method. We used 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT), scratch wound healing, and gelatin zymography assays to observe the cytotoxic effect, anti-migratory activity, and MMP9 expression, respectively, in CCA-1.1 or PGV-1-treated cells.RESULTS: Level of MMP9 was found significantly overexpressed in the primary tumor and metastasis nodal, while TP53 mutation sample types were observed and influenced the survival outcome in colon cancer patients. CCA-1.1 and PGV-1 exhibited strong cytotoxic activity after 24 and 48 h treatment against WiDr cells. The migration assay demonstrated that PGV-1 and CCA-1.1 at 1 mM inhibited cell migration up to 40% after 48 h in single and combination with doxorubicin. The MMP9 expression was significantly inhibited by 0.5 mM CCA-1.1.CONCLUSION: This study emphasizes that the anti-migratory effect of CCA-1.1 is better than PGV-1 via MMP9 suppression on WiDr. Thus, CCA-1.1 is prominent to be developed as an anti-metastatic agent.KEYWORDS: chemopreventive curcumin analog 1.1 (CCA-1.1), PGV-1, WiDr cells, anti-migration, MMP9
Citrullinated Histone H3 Level as a Novel Biomarker in Pediatric Clinical Sepsis

BACKGROUND: Sepsis is still leading cause of death in critically ill children. Early recognition of sepsis and treatments are needed to reduce its mortality. The use of citrullinated Histone H3 (Cit-H3) as an early sepsis marker and outcome predictor has been validated in previous studies among adults. However, only one study in pediatric meningococcal sepsis was reported with contradictory results. This study aims to determine Cit-H3 levels in pediatric clinical sepsis and analyze its association with sepsis severity and survival rate.METHODS: A prospective observational cohort study involving 67 pediatric subjects clinically diagnosed with sepsis was conducted. Cit-H3 levels, Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score, and Pediatric Sequential Organ Failure Assessment (pSOFA) score were assessed at the time of diagnosis (0-hour) and 48 hours later. Pearson Correlation test was used to determine the correlation between Cit-H3 levels with PELOD-2 and pSOFA scores and receiver operating curve to find the cut-off of Cit-H3 levels on clinical sepsis patients.RESULTS: Among clinically sepsis patients, the median Cit-H3 level was 1,210 (800-32,160) ng/mL, with optimal cut-off point ≥1200 ng/mL (sensitivity 83.3% and specificity 75.7%) to discriminate sepsis. The median Cit-H3 levels at 0-hour were lower in survivor compared to non-survivor group (p=0.016). Cit-H3 level was able to predict mortality with optimal cut-off point ≥1,200 ng/mL, sensitivity 72.2% and specificity 57.1% (AUC of 69.2%; p=0.017). Using survival analysis, Cit-H3 was significantly associated with the mortality rate (p=0.023; hazard ratio of 3.45).CONCLUSION: Cit-H3 level could be potential to predict pediatric sepsis events and its outcome.KEYWORDS: citrullinated histone H3, neutrophil extracellular traps, pediatric sepsis, PELOD-2 score, pSOFA score, survival

BACKGROUND: T lymphocyte activation depends on the balance of co-stimulatory and co-inhibitory signals determined by Cluster of Diffrentiation (CD)28 and Programmed Cell Death Protein 1 (PD-1) expression. Alteration in CD28 and PD-1 expression might affect the progression of chronic hepatitis B (CHB). Current study was conducted to evaluate the correlations of the CD28 and PD-1 expressions of T lymphocytes and CHB progression.METHODS: Subjects were recruited, selected and divided into 3 groups, inactive CHB, active CHB and CHB with End-Stage Liver Disease (ESLD). HBeAg was determined by using Enzyme-Linked Fluorescence Assay while HBV-DNA was carried out by the RT-PCR method. Numbers of T lymphocytes expressing CD3, CD4, CD8, CD45, CD28 and PD-1 molecules were determined by flowcytometry. RESULTS: There was no significant difference in the expression of CD28 by CD4+ and CD8+ T lymphocytes of inactive CHB, active CHB and CHB with ESLD subjects. There was also no significant difference in the expression of PD-1 in CD4+ lymphocytes of inactive CHB, active CHB and ESLD subjects. In contrast there was a significant increase in the expression of PD-1 in CD8+ T lymphocytes of ESLD subjects.CONCLUSION: CD28 expression among CHB subjects was within normal range and not related to disease progression, but PD-1 expression of CD8+ T lymphocyte was increased along with disease progression, especially in CHB subjects with ESLD. This suggests that PD-1-overexpressed CD8+ T lymphocyte play a role in increasing CHB disease progression.KEYWORDS: chronic hepatitis B, CD28, PD-1, T lymphocyte, disease progression

BACKGROUND: Millions of cells in multicellular organisms regenerate every day to replace aged and died cells. Effective cell clearance (efferocytosis) is critical for tissue homeostasis, as the human body recycles its cellular components. We summarize what is known about the mechanisms of efferocytosis and how it impacts the physiology of the organism, effects on inflammation and the adaptive immune response, as well as the consequences of defects in this critical homeostatic mechanism in this review.CONTENT: Cell death is the process by which the human body replaces aged or damaged cells with new ones. It can be triggered by genetically encoded machinery or regulated cell death, or by specific pharmacologic or genetic interventions, resulting in accidental cell death. Dying cells release signals that entice phagocytes to engulf them in a process known as efferocytosis. Efferocytosis is a multistep process involving the release of “find me” and “eat me” signals and destruction of death cells by phagocytes. Different types of cell death including apoptosis and necroptosis can express pro- or anti-inflammatory signals via macrophage activity modulation.SUMMARY: Failed or ineffective efferocytosis can result in disruption of tissue homeostasis, which can contribute to the development of chronic inflammatory diseases such as atherosclerosis, obesity, diabetes, and heart failure. Therefore, any therapeutic strategy that enhances efferocytosis will have a beneficial effect on the treatment of these metabolic disorders.KEYWORDS: apoptosis, necroptosis, phagocytosis, efferocytosis, macrophage.
