Authors: AIT HAMADOUCHE Yasmine , DIB Soulef , MECHOUET Ouezna
Published: July 2024

This research work is part of a project to develop the natural substances of higher basidiomycetes from Algeria’s forest.  This study aimed to evaluate the bioactive compounds of higher fungi, by quantifying phenols and flavonoids using spectrophotometry. The assay, showed that the highest quantity of flavonoids was recorded in the extract of Trametes quercina (10.27 ± 0.015 mg QE/g), followed by Suillus mediterraneensis (7.82 ± 0.011 mg QE/g). For phenols, amount of 442.23 and 432.88 mg GAE/g were respectively found in Lactarius zonarioides and S. mediterraneensis. In addition, TLC chromatographic screening was carried out for the first time in order to select higher basidiomycetes containing secondary metabolites. The results reported that all the basidiomycete extracts are rich in phenols, tannins and flavonoids with a similarity of secondary metabolites between the different extracts. Following these chemical investigations, eight extracts showing a phyto-stimulating effect were selected for analysis by high-performance liquid chromatography (HPLC). The presence of flavones and flavonols was detected: Flavones were found in Agaricus bisporus, Boletus sp., Pleurotus dryinus, S. mediterraneensis, Coprinus atramentarius, T. quercina and Xerocomus sp. On the other hand, flavonols were found in C. atramentarius, Pleurotus ostreatus and P. dryinus. Additionally, tannic acid was found in S. mediterraneensis, chromatographic profiles show that basidiomycete extracts produce a wide range of secondary metabolites, with many compounds common to all extracts. The study of plant growth enhancement by extracts of basidiomycetes on eggplant, in hydroponic conditions, is a novelty. The chemical study confirmed that these extracts do indeed contain a diversity of bioactive products that contribute to increasing plant yield, thus offering strong agricultural potential.

Seed germination is a vital process, yet extremely sensitive to salinity. This is particularly true for coastal halophytes like the annual oilseed species Cakile maritima, which faces the simultaneous impact of wind, salt-spray and seawater inundations in its natural biotopes. At the early developmental stages, this may jeopardize seed germination, plant establishment capacity and hence its development and persistence. Osmopriming is a pre-sowing approach aiming to improve seedling emergence and establishment in adverse environments. Here, we investigate the effect of proline (at 0, 1, 5, and 20 mM) pre-treatment on salt tolerance of C. maritima at the juvenile stage under salinity (0, 100, and 200 mM NaCl). Proline seed priming enhanced the germination rate (28% to 92%) and promoted seedling establishment of C. maritima by stimulating α-amylase activity even at the highest salinity (+55 %). Besides, after transfer of non-germinated seeds on distilled water, salt impact was fully reversible. At the seedling stage, chlorophyll fluorescence parameters showed that this osmoticum increased the maximal quantum yield of PSII photochemistry (Fv/Fm) and the quantum yield of photochemical energy conversion [Y(II)]. In contrast, the quantum yield of nonregulated nonphotochemical energy dissipation [Y(NO)] and the quantum yield of regulated nonphotochemical energy dissipation [Y(NPQ)], which might be correlated to the mitigation of the salt deleterious effects on PSII. Proline and carbohydrate concentrations also increased following priming. Overall, our data provide strong arguments for using proline at low doses (1 and 5 mM) as a successful priming agent to alleviate salinity-induced adverse effect on plants.

Seed dormancy is a major impediment for the production of Salvia officinalis L. (sage) seedlings. This study aims to test seed priming methods to break the dormancy of sage seeds in controlled conditions. Seeds were subjected to four treatments respectively hydropriming, magneto-priming, electro-priming and control with no seed priming techniques. During germination development stage all parameters were registered according to BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) standardized scale. Daily assessments were made, germination indices were calculated, new germination secondary stages were observed and described, and daily range for each secondary stage were obtained. All priming methods had different effect on sage seeds. The hydropriming treatment was the most effective with 70% seeds germinated in 10 days. Sage seeds from magneto-priming determine more than 50% seeds to germinate in only 8 days. Control and electropriming treatment showed a similar value of seed germination, set around 64-65%. In control, electro- and hydropriming treatments are necessary 6 days for the achievement of more than 50% seed germination, while for magneto-priming are necessary 8 days. Hydropriming has the highest germination index, significantly higher than control and magneto-priming. During the germination, hydropriming shows a gradual transition of seeds from one BBCH sub-stage to another, while electro- and magneto-priming induce a heterogenous variation through the entire process. Overall, the hydropriming treatment registered better results of sage germination compared to the control treatment.

Published: July 2024

The need of an automated support system that helps beekeepers maintain and improve beehive population was always a very stressing aspect of their work considering the importance of a healthy bee population. This paper presents a proof of concept, further referred as a PoC solution, based on the Internet of Things technology which proposes a smart monitoring system using machine learning processes, diligently combining the power of edge computing by means of communication and control. Beehive maintenance is improved, having an optimal state of health due to the Deep Learning inference triggered at the edge level of devices which processes hive’s noises. All this is achieved by using IoT sensors to collect data, extract important features and a Tiny ML network for decision support. Having Machine Learning inference to be performed on low-power microcontroller devices leads to significant improvements in the autonomy of beekeeping solutions.

Published: July 2024

Abstract Brazil has one of the greatest diversity of ferns and lycophytes in the world, especially in its humid forests. The knowledge about these plants in the 27 federative units is uneven and can potentially hamper conservation actions aimed at them. In the state of Sergipe, collections of these groups have been sporadic and about 50 species have been cataloged so far, a low number when compared to other states. This study aimed to compile the species of ferns and lycophytes occurring in Sergipe based on herbaria materials and recent samples collected. Therefore, specimens from herbaria were accessed, together with online databases, as well as 13 botanical expeditions were carried out in three areas. Our study recorded of 20 families, 44 genera and 86 species (75 ferns and 11 lycophytes), with eight new records for the state. The most representative families were Pteridaceae (21 spp.), Polypodiaceae (12), Anemiaceae (nine) and Selaginellaceae (eight). The genera Adiantum L. (eight spp.), Anemia Sw. (nine spp.) and Selaginella P.Beauv. (eight spp.) had the highest number of species. The study shows that efforts like these are extremely necessary and may eventually indicate the extent to which the richness of ferns and lycophytes in Sergipe is underestimated, also promoting researches in this area of Botany.
Mujeres-brujas y naturaleza: hechizos para re-existir y resistir
Authors: Parra-Valencia Liliana , Páez Alison Salazar , Fernandes Saulo
Published: July 2024

Resumen Presentamos una revisión teórica sobre la relación mujeres-brujas, naturaleza, re-existencias y resistencias afrodiaspóricas en Latinoamérica y el Caribe, ante la división moderna/colonial entre lo humano y no humano. Problematizamos las diversas formas de violencia y discriminación contra las mujeres subalternizadas, en particular aquellas denominadas “brujas”; también el silenciamiento epistémico moderno/colonial de los saberes otros. Los ejes de interpretación, construidos como categorías emergentes del análisis cualitativo, abordan la persecución de las mujeres-brujas y el capitalismo, la relación con la naturaleza, brujería y saberes otros, y la resistencia descolonial de las mujeres en la afrodiáspora. El reto para la Psicología está en descolonizar el modo de entender la naturaleza y proponer investigaciones capaces de acercarse a otras interpretaciones del mundo, otras formas de conocer, de ser y existir, como las de las mujeres-brujas. Su relación con la naturaleza, no sigue la ontológica moderna, dual, patriarcal y capitalista; por el contrario, las plantas, los animales, los minerales, entes y divinidades configuran su cotidianidad, sus re-existencias y resistencias.

Published: July 2024

ABSTRACT Objective: To investigate the association between the dimensions of the Health Belief Model (HBM) and complete vaccination for hepatitis B among healthcare workers (HCW). Methods: Cross-sectional epidemiological study with HCW in Primary Health and Medium Complexity Care. Univariate and bivariate analyses were performed to test the association between the outcome variable (complete vaccination for hepatitis B based on self-report) and the variables of the HBM dimensions. Prevalence ratio (PR) and its respective 95% confidence intervals (95%CI) were calculated. Results: 453 HCW participated. The prevalence of complete vaccination for hepatitis B was 56.9%. In the final analysis model, the following variables were associated with complete vaccination for hepatitis B: chances of having hepatitis B (PR=1.73) – related to the susceptibility dimension; disease severity (PR=0.74) – related to severity; reduced risk of absenteeism (PR=1.29) – related to benefits; not spending time to get vaccinated (PR=1.41) and not worrying about Events Supposedly Attributable to Vaccination or Immunization (PR=1.43) – related to barriers. Conclusions: The completeness of the hepatitis B vaccination schedule, reported by the investigated HCW, reveals the prevalence is below the target established by the Ministry of Health, which follows the national scenario of low coverage presented for other age groups. Understanding the risk perception and severity of hepatitis B can contribute to increasing the prevalence of vaccination for this infection.
Education by the Escola Nacional Florestan Fernandes as Transmodernization from Capitalist Consumerism
Authors: Hemais Marcus Wilcox , Quintão Ronan Torres , Barros Denise Franca
Published: July 2024

ABSTRACT Objective: to analyze the critical debates raised by the Escola Nacional Florestan Fernandes (ENFF) in one of its courses, in order to highlight how this education fosters self-defense initiatives that marketing should acknowledge in consumerist discussions. Theoretical approach: the decolonial concept of transmodernity and Paulo Freire’s pedagogy of the oppressed are used to base our analysis. Methods: with a decolonial perspective as our guiding epistemology, we collected data from an online course offered by ENFF. Initially, the authors viewed all videos individually, and subsequently, discussed the pre-analyses. The second round of analysis included coding the data, so we could reach categories of analysis. Results: an approach aligned with the pedagogy of the oppressed is adopted by ENFF’s, since it: raises awareness of its students about the hegemonic structure that oppresses them; criticizes the illusion this oppressive structure creates about benefiting all, emphasizing that a rupture is only possible if the oppressed are behind it; and proposes a path beyond this oppressive structure, specifically through agroecology. The education by ENFF can thus be interpreted as a transmodernization from capitalist consumerism, given it foments, from subalternized settings, self-defense awareness among its students, who come from oppressed contexts. Conclusions: consumerism has been scantly questioned in marketing. However, its activism has been hardly able to deal with the racism, sexism, and coloniality associated to this concept. By presenting a form of educational perspective that resides outside of capitalist principles, a new self-defense model can be considered in the search to protect individuals from market forces.
Comprehensive and integrated care in healthy aging policies: comparison between Portuguese and Brazilian health systems
Authors: Weber Larissa , Craveiro Isabel , Colussi Cláudia Flemming
Published: July 2024

Abstract This study investigated how comprehensive and integrated care is expressed in the legislation of the Portuguese National Health Service and the Brazilian Unified Health System, especially in healthy aging policies. This qualitative and exploratory study was based on documentary research and included laws, decrees, ordinances, and plans, published until 2020. Twenty-four documents were selected, 12 from Portugal and 12 from Brazil. The data was subjected to content analysis. The findings indicated that Primary Health Care is the level of care responsible for integrating care in both countries. Both invested in the formation of care networks, intersectoral coordination, and the adoption of information and communication technologies to facilitate integration. Healthy aging policies have emphasized the importance of care at the community level, integrating users, their families, health equipment, and other sectors, promoting autonomy, and preventing chronic diseases and violence. The transformations in both countries follow scientific evidence published by the World Health Organization and research centers focused on healthy aging that contributes to making their systems more efficient and problem-solving. It is hoped that the aspects discussed will contribute to the development of successful ways of overcoming current challenges, such as those imposed by the COVID-19 pandemic.

Published: July 2024

Resumo Este artigo tem como objeto a avaliação de desempenho docente na Educação Superior. Diante da obrigatoriedade legal de avaliar o desempenho do professor para fins de concessão de progressão e/ou promoção na carreira e da resistência de sindicatos e associações docentes a essa avaliação, pergunta-se: é possível avaliar o desempenho para além dos aspectos regulatórios da carreira, de tal forma que se possa resistir à implantação da cultura da performatividade em Instituições de Educação Superior? As análises foram feitas a partir: da inclusão daquela avaliação na carreira do magistério sob influência de organismos internacionais; da incorporação de elementos próprios da cultura performativa; da resistência, por meio do uso formativo dos resultados da avaliação de desempenho docente; e dos relatos de professores que atuam em cursos de graduação. As considerações finais indicam que a resistência à cultura performativa deve ser um compromisso assumido tanto individual quanto institucionalmente.
Strength behaviour of stacked phosphogypsum incorporating dissolution–recrystallisation equilibrium
Authors: Cai Zhang-Zheng , Ke Han , Zhang Peng-Ze , Lan Ji-Wu , Ma Peng-Cheng , Hu Jie , Xiao Bo , Chen Yun-Min
Published: July 2024

Large phosphogypsum (PG) stacks risk dam failure, with an insufficient consensus on the shear strength parameters for stability analysis. To this end, a combination of scanning electron microscopy and triaxial tests was undertaken to investigate the underlying mechanism between crystal structure and shear strength of in situ and remoulded PG samples. The shear strength and deformation of PG were significantly affected by dissolution and recrystallisation. Dissolution weakened the cementation between particles, leading to a stabilisation of approximate 11 kPa under different confining pressures in the initial shear stage. The hardening phenomenon was related to the formation of cluster crystals under saturated conditions. An increase from 1·57 to 1·73 in the critical state stress ratio on remoulded samples occurred as the K0 consolidation time increased from 4 to 28 days. The compressive deformation of PG is accompanied by chemical consolidation, which is mainly impacted by the consolidation conditions (saturation) rather than the consolidation time. In the engineering design of the PG stacks, ϕ′ could be taken to a higher value at saturation and c′ could be higher when the dry density is higher than 1·2.

Joint use of sodium silicate and polysaccharides in the flotation of talcose copper-nickel ores
Authors: Lavrinenko A. A. , Kuznetsova I. N. , Golberg G. Yu. , Lusinyan O. G.
Published: July 2024

The paper considers the combined effect of polysaccharides (carboxymethyl cellulose and carboxymethyl starch) with sodium silicate in the f lotation of talcose copper-nickel ore. The analysis of the f lotation results and the assessment of hydrophobicity and surface charge of minerals showed that the composition of carboxymethylated  polysaccharides  and  sodium  silicate  hydrophilizes  the talc surface more effectively than each of the reagents separately. Moreover, sodium silicate alone hardly depresses the talc surface at all. The depression of f lotation-active silicates is effective when polysaccharide and sodium silicate are sequentially supplied. Under these conditions, sodium silicate makes a significant contribution to increasing the negative charge on the talc particles surface. The effect is more pronounced for compositions with starch, characterized by a lower degree of substitution compared to cellulose. It results in a significantly reduced recovery of f lotation-active magnesium-containing silicates and a slight decrease in sulfide recovery. To determine the features of the mechanism of talc and sulfide minerals depression in f lotation, we performed calculations using the extended DLVO theory based on the obtained values of the zeta potential and force of detachment. We established that sulfide minerals have no potential barrier preventing their interaction with an air bubble, regardless of the compositions of the studied depressants used. We propose the following interaction mechanism: when sodium silicate is supplied first, the talc basal surface is very insignificantly hydrophilized as SiO(OH)– ions are not easy to fix. On the contrary, when the carboxymethylated polysaccharide is supplied first, significant hydrophilization of the talc surface with carboxyl groups occurs due to the hydrophobic interaction between the corresponding regions of the macromolecule and the talc basal surface.
The Jihadi Insurgency in Cabo Delgado: Ideology, Protagonists and Causes
Authors: Bonate Liazzat J. K.
Published: July 2024

Based on fieldwork interviews with the internally displaced Muslims from the regions affected by the insurgency, such as Palma, Mocímboa da Praia, Macomia, Quissanga and others, this article unpacks the context, ideology and protagonists that gave rise and afforded sustenance to the insurgency in Cabo Delgado. After providing an overview of the historical trajectory of Islam in Mozambique, the article presents the ideological and historical underpinnings of the contemporary global jihadi movements, expanding into Africa and Mozambique. The article argues that for jihadism to take roots in any place, there should exist militant protagonists and the grievances that serve as emotional entry points for recruitment. Thus, the article examines the processes by which jihadi protagonists emerged in various communities and the grievances they articulated in order to provoke the insurgency against the State.
Growing Apart: The Historical Construction of Difference in Northern Cabo Delgado, Mozambique
Authors: Santos Ana Margarida Sousa
Published: July 2024

How do past experiences of violence map onto present day narratives of insurgency in northern Mozambique? In the insurgency that began in northern Mozambique in 2017, narratives of past violent encounters and animosity between different ethnic groups sharing the coastal space emerge as a way of making sense of the conflict. This article explores the ways these narratives stem from existing historical tensions between Makonde and Mwani inhabiting the northern districts of Cabo Delgado. Drawing on ethnography and oral history to highlight the continuities in narrative, I will explore the ways in which current violence is interpreted through references to pivotal moments of violence in the past. I will address the historical construction of difference between Makonde and Mwani to consider what it may tell us about the fractures that underpin the insurgency.
The Morality of Schooling: Women's Education as an Arena for Social Tension in Cabo Delgado
Authors: Rosario Carmeliza
Published: July 2024

In this article, I reflect on education as a continuing arena of tension for people in Cabo Delgado. The tension between formal (state-sponsored) and religious education as a backdrop of the conflict in Cabo Delgado has been widely mentioned but largely misunderstood. Scholars have consistently mentioned poverty and people's lack of access to formal education as drivers of the disenfranchisement that has led to violent extremism in the province. There are also references to how the insurgent movement has shunned formal education in favour of Islamic teachings. The existing literature about the insurgent's rejection of state-sponsored education, especially for girls, fails to address a trajectory whereby formal (state-sponsored) education has been a field of tension for a long time. Similar tensions happened across the Swahili coast in both English and French colonies. From interviews focused on women's relationships and experiences with both the colonial and postcolonial state, it emerged that Muslim populations in Cabo Delgado, particularly on the coast, have a long history of suspicion towards state-sponsored education. This includes showcasing a locally established practice for women's education that predated and existed alongside formal education. This follows that cultural and religious dynamics do not preclude women's influence in society, particularly education. In fact, it relies on her active participation. At the same time, despite potential violent cooptation, in the context of the conflict, the insurgent movement is able to tap into the existing tensions, including that around state-sponsored education. Evidence from the field indicates that, despite the disadvantages of resisting formal education, religious education remains central to most people, not just those following the extremist movement. What may appear to be an extremist rupture from mainstream practice should be understood within a logic operating on shared and familiar values.

Optimizing Structural Integrity of Fighter Aircraft Wing Stations: a Finite Element Analysis Approach
Authors: Haider Bhutta Aun
Published: July 2024

Modern fighter aircraft are equipped with multiple stations on the fuselage and under the wings to accommodate various external stores, both jettisonable and non-jettisonable. Each configuration undergoes airworthiness certification, including structural analysis of individual stations within the carriage flight envelope. This study focuses on the structural analysis of a fighter aircraft wing station within this specified envelope. To perform this analysis, the wing station is extracted from the comprehensive global wing model, creating a sub-model with equivalent stiffness properties. Utilizing ANSYS Workbench®, Finite Element Analysis (FEA) is conducted for critical load cases to determine the Factor of Safety (FoS). The initial analysis reveals that the wing station has an FoS of 1.2 under the maximum design load. Prestressed modal and buckling analyses indicate a 10% increase in stiffness due to stress-stiffening effects. To further enhance load-carrying capacity, parametric design changes are introduced. Increasing the bolt diameter from 8 mm to 10 mm raises the FoS to 1.33, resulting in an 8% increase in the maximum load-carrying capacity of the wing station. This comprehensive approach, employing FEA, ensures the wing’s structural integrity under static load conditions within the carriage envelope. The study's findings support the wing station's enhanced performance and contribute to safer and more efficient aircraft operations.
Determination of the number and width of class intervals using R
Authors: José Moral de la Rubia
Published: July 2024

The histogram and frequency table are fundamental tools for describing continuous variables or discrete variables with many values. Most statistical programs are not flexible, nor do they explicitly state the rules they use to construct histograms or provide guidelines for constructing interval tables. However, by programming or applying the appropriate procedures, this can be achieved with Excel, MATLAB, and R. The objective of this methodological article is to provide a script for the R program to calculate the number and width of class intervals using eight rules that provide a uniform width (four depending on the sample size and four based on optimal width). The script automates the selection of the rule to produce an interval table and a histogram with overlaid density and normal curves. Additionally, symmetry is assessed using the D’Agostino test, mesokurtosis with the Anscombe-Glynn test, and normality with the Lilliefors, Anderson-Darling, and Shapiro-Francia tests. Furthermore, three rules are calculated that provide variable width: one for samples of 25 to 39 data points (multiple of 5) and two for samples of at least 40 data points (Mann-Wald and Moore). Once one of these three rules is chosen, it is applied to the normality check using the likelihood ratio test. Additionally, an optimal histogram provided by R from its basic library is computed. The script is applied to two examples and is adapted to the small samples (< 25 data points) in a third example. It is concluded that this script can be of practical and didactic use.

The Ghaghara River is one of the longest tributary of the Ganga River. The Ghaghara, a snow fed river is well known for channel shifting/migration. It was analyzed for lateral migration using multi-temporal satellite images and SOI toposheets. It shows 4.2 to 6.1 km lateral migration in last 45 years (1975–2020) between Bahraich and Deoria in the state of Uttar Pradesh. The lateral migration on the left side of the river (NNE) is 6144, 4838, 6475 and 4755 m, whereas on the right side (SSW) is 7021, 4555, 4718 and 4257 m during 1975–1990, 1975–2000, 1975–2010 and 1975–2020, respectively. The rate of migration (m/year) on left side (NNE) is 410, 194, 185 and 106, whereas on the right side (SSW) is 468, 182, 135 and 95 during 1975–1990, 1975–2000, 1975–2010 and 1975–2020, respectively. The major factors such as heavy precipitation, reactivation of chute channels, deposition of sediments, breaching of embankments and sand mining etc. might be responsible for the lateral migration of the river. Human settlements should be constructed away from the migration-prone area and regular monitoring and management system needs to be in place to mitigate the impacts of such natural events.

We investigate the site characterization and shallow shear velocity profiles from the analysis of the Horizontal to Vertical Spectral ratio (HVSR) around the Hyderabad metropolitan region (HMR), which falls under the southern Indian shield. This work uses both the ambient noise and microearthquake data to compute the HVSR, and additionally the Random Decrement technique to compute the HVSR of extracted Rayleigh waves. This study indicates comparable HVSR curves at each station with the three different datasets, from which we obtain the average dominant frequency (f0) and amplification value (A0). They are further used to calculate the seismic vulnerability index value (Kg). We observe that the value of f0 around the HMR is not fixed, but is varying in the range of 3.4 to 18 Hz, whereas the value of A0 is in the range of 1.7 to 12 approximately and Kg in the range of 0.16 to 1.68 approximately, with an exception of ∼ 33 at VKB (Vikarabad) station, which may be due to a local unconsolidated sub-surface structure. Based on the Diffused Field Assumption (DFA), we invert the average HVSR curves and average dispersion curves of Rayleigh waves, and provide the shallow shear velocity profiles up to 300 m, along with an approximate estimate of VS30 (in upper 30 m depth). The estimated VS30 values vary between 911 to 3143 m/s, falling under the classifications A and B (mostly Hard Rock and Rock type) of National Earthquake Hazards Reduction Program (NEHRP) (BSSC, 2001). However, our study shows some stations with shear velocity inversions at shallow depths within 300 m, indicating layers of low velocity, needing further study. In the absence of detailed near-surface findings, these findings are valuable inputs for geotechnical engineering studies and urban-city planning around the HMR, and emphasizes the effectiveness the HVSR method to determine sub-surface topography and/or unknown soil structures as an economical investigation viability.

Event-based hydrologic models are very useful to predict peak flow and flood volume, particularly in semi-arid regions. In HEC-HMS software methods selected for loss, transformation, routing and base flow were soil conservation service (SCS) curve number (CN), SCS unit hydrograph (UH), Muskingum and recession, respectively. A total of six extreme events from the year 2011 to 2019 were selected, out of which four were used for calibration, one each for validation and application. The developed model can identify the peak discharge and flood volume satisfactorily at 2-hour intervals. During validation performance statistical viz. percent difference in runoff volume (DV%), percent difference in peak flow (DP%), Nash Sutcliffe Efficiency (NSE), percent bias (%BIAS), coefficient of determination (R2) and ratio of the root mean square error to the standard deviation (RSR) were −3.68, −25.93, 0.52, 3.52, 0.53 and 0.69, respectively. The sensitivity analysis revealed that the CN is the highest sensitive parameter followed by the storage time constant (K), which affects the peak discharge. Whereas, for flood volume, CN is the highest sensitive parameter followed by the recession constant (Rc). The relative sensitivity of CN for peak flow and flood volume were 2.11 and 1.73, respectively. Out of center maximum rainfall (CeMR) and cumulative maximum rainfall (CuMR) distribution, CeMR distribution has given higher peak discharge for all rainfall duration. The rainfall characteristics of the 2016 flood event suggest a hypothetical 9-day rainfall duration can be considered. The 9-day event with CeMR gives 70.64% higher discharge as compared to the observed peak discharge during the 2016 flood.
Interprofessional Education Collaboration between Chung Ang Medical School and Sungshin Nursing School
Authors: Kim Young Ju
Published: July 2024

Interprofessional collaboration is crucial for patient-centered care and safety. Since healthcare students will be part of interprofessional teams in the future, they need to understand the unique contributions of various healthcare professions to patient care and develop skills in collaboration, communication, leadership, and mutual respect. In response to this need, healthcare faculties have adopted interprofessional education as an innovative teaching method. However, traditional health education has typically taken place within individual schools, resulting in a limited understanding of other professional roles and identities. In our study, we introduced an interprofessional education model involving two different colleges. A total of 152 undergraduate students, comprising 101 medical students from Chung Ang University and 51 nursing students from Sungshin Women’s University, participated in the program. A one-day interprofessional education program was conducted to promote collaboration between medical and nursing students. The program included team building and communication games, scenario-based simulations, such as a “room of errors,” and tabletop exercises. Key factors for successful interprofessional education include carefully planned scheduling, leadership, and commitment from participating colleges, faculty support and training, the use of diverse teaching methods and technology, and alignment regarding educational directions among the faculty. We believe that this model may provide valuable insights for healthcare institutions aiming to develop and implement interprofessional curricula.

Published: July 2024

This protocol has been optimized for the recombinant expression of a codon-optizimed Pfu-Sso7d DNA polymerase. This is a fusion protein composed of the Pfu enzyme from Pyrococcus furiosus for DNA amplification by PCR fused to a small 7 kDa protein from Sulfobulus solfataricus that binds to double-stranded DNA without any preference for specific sequences, thus enhancing polymerization processivity without affecting the catalytic activity or thermal stability of the enzyme. The goal of this protocol was to eliminate the use of large volumes for dyalisis and potential issues with the protein crashing out of the solution due to the use of concentrators for buffer exchange of this enzyme into storage conditions. We also eliminated the use of DTT, which is often found in other similar protocols. The plasmid encoding the codon-optimized Pfu-Sso7d enzyme used here can be found on reclone.org
