Published: August 2023

ABSTRAK  Pemanasan global telah menjadi momok untuk kehidupan manusia. Tindakan manusia yang tidak terkontrol mengakibatkan tercemarnya lingkungan, pencemaran lingkungan semakin tidak terkendali pada masa industrialisasi karena industri mengeksploitasi sumber daya alam dan menghasilkan limbah industri berbahaya yang tidak di kelola dengan baik. Walaupun dengan adanya industri dapat meningkatkan pendapatan nasional, namun jika tidak ada pengawasan maka kehidupan manusia yang harus di korbankan. Penelitian ini bertujuan untuk mengetahui pengaruh kinerja lingkungan dan tingkat pertumbuhan berkelanjutan terhadap kinerja keuangan perusahaan di Indonesia. Kinerja lingkungan di ukur dengan PROPER dengan melihat kinerja perusahaan dalam pengelolaan lingkungannya, sedangkan tingkat pertumbuhan di ukur dengan sustainable growth rate. Pemilihan sampel menggunakan teknik purposive sampling dan menghasilkan 30 perusahaan yang bergerak di sektor manufaktur, pertanian dan pertambangan selama periode 2018-2021. Teknik analisis menggunakan regresi data panel. Hasil penelitian menunjukkan kinerja lingkungan tidak berpengaruh terhadap kinerja keuangan perusahaan karena memproduksi produk yang ramah lingkungan membutuhkan biaya ekstra sehingga laba yang di hasilkan perusahaan berkurang. Sedangkan tingkat pertumbuhan berkelanjutan berpengaruh terhadap kinerja keuangan karena perusahaan yang baik akan menjaga kepercayaan dan meningkatkan investasi investor sehingga naiknya penjualan yang akan meningkatkan laba serta perusahaan akan memiliki umur panjang yang menjadi salah satu faktor penentu keputusan berinvestasi.

This study identifies transformational leadership, human capital, and job satisfaction as significant determinants of organizational performance. The analysis focused on the employees of diverse manufacturing organizations in Bangladesh treated as the targeted population. The data collection was conducted using a survey methodology, wherein a questionnaire was distributed to the participants via postal mail along with a cover letter to enhance comprehension. The ultimate sample consisted of 294 participants, obtained from a pool of 400 individuals who were sent survey questionnaires. The response rate for the survey was 73.5%. Furthermore, a significance level of 5% was employed to assess the hypotheses, and the data pertaining to the research objective of this study were analyzed using SPSS software. The study results indicate that organizational performance is significantly influenced by transformational leadership, human capital, and job satisfaction. These three independent variables explain (R2) 59.6% variance in organizational performance. It is also found that transformational leadership (β-value = 0.443) has the highest impact on the organizational performance of manufacturing firms. This study provides implications for organizational management to improve long-term organizational performance.

Authors: Guo Wen-Dar , Chen Wei-Bo , Chang Chih-Hsin
Published: August 2023

This study coupled the ensemble learning method with residual error (RE) correction to propose a more accurate hydrologic model for the time-series prediction of the reservoir inflow. To enhance the prediction capability of the model in mountain catchments, three deep learning (DL) models, namely the encoder–decoder gated recurrent units (ED-GRU), encoder–decoder long short-term memory network (ED-LSTM), and combined convolutional neural network with LSTM (CNN-LSTM), were deployed to train reservoir inflow prediction model for the lead times of 1–24 h. The prediction outputs from three DL models were then incorporated into the categorical gradient boosting regression (CGBR) model to resolve the highly non-linear relationship between model inputs and outputs. In the final procedure, the RE correction method was implemented by using the outcomes of the CGBR model to construct the proposed hybrid model. The proposed model was applied to simulate the hourly inflow in the Shihmen and Feitsui Reservoirs. The proposed model achieved improved performance by an average proportion of 66.2% compared to the three DL models. It is demonstrated that the proposed model is accurate in predicting the reservoir peak and total inflows and also performs well for storm events with multi-peak hydrographs.
Tariff setting for the sustainability of communal water points in Mangochi District, Malawi
Authors: Andreah Kondwani , Manda Mtafu , Tembo Mavuto
Published: August 2023

The Malawian Government adopted a community-based management model for rural water supply systems, which assumes that users would cover costs related to the operation and maintenance (O&M) of their communal water points through regular cash contributions. These communal water points are mostly boreholes fitted with Afridev hand pumps. However, studies have shown that Afridev hand pumps continue to fail within 3–5 years after installation, despite having a design lifespan of 10–15 years, mostly due to insufficient O&M. Therefore, this study assessed the adequacy of tariffs being used at different water points in Mangochi District in Malawi through a household (HH) survey with a sample size of 288 HHs and a market prices survey. The results showed that 90% of the HHs were making contributions that could not sustainably support the lifecycle O&M costs or the afterlife replacement of the Afridev hand pump. This study suggests a consistent minimum annual water point fund collection of MWK142,050 (US$172.29)1. It is recommended that the study be replicated in other areas. It is also recommended that further studies should focus on HH affordability with respect to the recommended tariff.

Authors: Żądło Andrzej
Published: August 2023

Współczesny kontekst życia sprzyja pogłębieniu refleksji na temat ojczyzny. Żyjemy w czasach, w których idea ojczyzny na nowo odżywa w naszej świadomości, budzi w nas troskę o to, co jest z nią związane, co sprzyja jej bezpieczeństwu i rozwojowi oraz życiu w pokoju. Święta liturgia, nie deprecjonując ojczyzny ziemskiej, zaszczepia oraz gruntuje w uczniach Chrystusa wiarę w życie wieczne w domu Ojca, w którym jest mieszkań wiele (por. J 14,2). Tę ojczyznę przygotowaną dla wierzących w niebie liturgia Kościoła nazywa wieczną lub prawdziwą – taką więc, do której wierzących prowadzi Jezus, Prekursor życia szczęśliwego w niebie. Według przeanalizowanych w niniejszym artykule tekstów Mszału, zadanie stawiane uczniom Chrystusa polega na tym, by przebywanie i życie na ziemi przybierało znamiona drogi prowadzącej do ojczyzny niebieskiej.

The Left ventricular ejection fraction and left ventricular volumes assessed from 99mTC
single photon emission tomography technique during stress and rest in relation to age in
normal volunteer students.
Authors: Kadam Satar M.
Published: August 2023

The heart is subject to structural and functional changes with advancing age. Left
ventricular compliance appears to decline with age, which could explain why the
elderly have such a high rate of heart failure. Changes in heart function with age
are associated with an increased risk of cardiovascular death and morbidity. Various techniques have been used to measure the impact of age on heart structure and
function. Subject and methods: The study included 221 healthy adult male and
female volunteers (160 females and 61 males, 20–80 years of age). All healthy
subjects volunteered to participate in this study. They were classified according to
their age. All healthy subjects enrolled in the study underwent myocardial perfusion imaging following the 2-day rest–stress 99mTc sestamibi (GSPECT) protocol.
At rest and during stress, end-diastolic volume, end-systolic volume, and ejection
fraction using the GSPECT software were assessed both at rest and during stress
for comparison. The following parameters were measured: left ventricular
end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV),
and left ventricular ejection fraction (LVEF). The results show that the change in
left ventricular ejection fraction (LVEF) decreased during rest and stress in all age
groups. In contrast, the change in left ventricular end-systolic volume (LVESV)
increased during stress and rest compared with the left ventricular end-diastolic
volume (LVEDV) for all ages. Results show a significant change in EDV, ESV,
and EF% (16.49%, 30.35%, -7.49%) with p-value < 0.05 for the groups (20- 49).
Also a significant change in EDV, ESV, and EF% (12.13%, 24.86%,-1.62%),
respectively, with p-value <0.05. for age range (50-80) years. In conclusion, in
people with no cardiac functional or structural problems, the aging process is
linked to considerable alterations in left and right ventricular EF, ESV, and EDV.
When assessing SPECT with 99mTc investigations, our findings highlight the need
to adopt age-adapted data as a reference standard.

Throughout the agricultural season fall 2020/2021, research has been carried out
in the vegetable research field of the Dept. of Horticulture and Landscaping,
Univ. of Mosul, to investigate the genetic performance of several Faba bean genotypes under consideration of Mosul conditions. Seeds of 7 bean cultivars were
sown (S2009-175, FBSPN2, Aguadulce, ILD1814, Histal, Favada Orio, and
Luzde otono). The genotypes differed considerably in all of the examined variables at a probability threshold of 5%, according to the results of an ANOVA table
analysis of sources of variance. The genotype FBSPN2 has been superior in characteristics of plant height and seed yields regarding each of the experimental
units. S2009-175 produced the maximum number of dry pods for each plant,
Favada Orio in the trait of seed length and pod weight, and Histal produced the
maximum diameter of a pod and number of seeds in each one of the pods and diameter of seed for each experimental unit. The genetic and phenotypic variance
was high for the weight of the pods for each one of the plants, the weight of 100
seeds, and the height of the plant, according to the results of the genetic parameter analysis, and the percentage of heritability in a broader sense had exceeded
60% for the traits, number of pods, and plant length. For the experimental unit,
dry pod weight for each plant, dry pods per plant, seed diameter, pod length and
diameter, dry seed yield, and 100-seed weight were all high, and genetic improvement for pod weight, seed weight, and weight of a 100-seeds was high as
well.

Published: August 2023

The objectives of this study were to detect and isolate the Parainfluenza-3 virus (PIV-3) in camels with naturally developed respiratory illness and to determine the titer of the isolates using the virus titration. Therefore, an overall 100 nasal swabs and jugular vein blood samples were collected from diseased camels in four districts in Wasit province (Iraq) from December (2019) to March (2020). The swabs were subjected to six subsequent passages on bovine kidney cell culture (BKCC) to isolate the virus and to confirm infection by molecular PCR assay. Fever (40°C), abundant runny nasal discharge, ocular discharge, coughing, depression, increased respiratory rate, abnormal breath sounds, and mainly wheezing are the most observed clinical signs. Positive findings were involved 24% by ELISA and 37% by RT-PCR. The age group from 1-2 years old showed a high infection rate, while the lower level was in the 4-6 years old group. Regarding season, the infection rate was high in winter compared to spring. Sheik Saad city appeared to have a higher infection rate than other districts. The positive samples inoculated into the Bovine kidney cell culture (BKCC) revealed the cytopathic effects (CPE) after three successive passages, which appeared as clumping and rounding with the progression of infection time at the 4th passage. Elongation and giant cell formation were shown in some isolates after the 5th and 6th passages until they reached complete detachments of the cells from the cell sheet. The titer of viral tissue culture infective dose (TCID50) of the 3rd passage was determined in BKCC cells at 10–3/0.05 ml, and the high titer was shown at the 5th and the 6th passages equal to 10-5/ 0.05 ml. In conclusion, PIV-3 is widespread among camels infected with respiratory illness; therefore, studies are necessary to detect the prevalence rate among camels in other Iraqi regions.

Authors: Hussein Jabal Amin , Abdulkaree Mohammed A.
Published: August 2023

Silicon can be used as a soil amendment to reduce deleterious soil salinity and improve nutrient availability under different irrigation water salinity
levels. Four treatments of Si (0,150 and 300 kg Si ha-1
as nano-silica and 300 kg
Si ha-1
as potassium silicate) along with four salinity levels of irrigation water
(1.65,3,6and 9 dSm-1
) were used to investigate their effect on soil salinity at
three soil depth ( 0-15, 15-30 and 30-45 cm ) and availability of N, P and K in
soil cultivated with tomato. The experiment was conducted under greenhouse
conditions using a random complete block design with three replicates. According to the results, increasing irrigation water salinity level increased soil salinity
and decreased available N, P and K to tomatoes. Si treatments decreased soil salinity and increased available amounts of N, P and K . Using 300 Kg Si ha-1 of
nano-silica caused the lowest soil salinity of 1.89, 2.51 and 3.23 dSm-1
for 0-15,
15-30, and 30-45cm depth, respectively and increased availability of N, P and K

The efficiency of Pseudomonas mendocina in biodegradation of chlorpyrifos
insecticides
Authors: Abbas Al-Khafaji Zahraa Khudhair , Sabah Hashim Hassanin , Jabbar Nasser Maryam , Dabbi Mohammed A.
Published: August 2023

At present, wide varieties of pesticides are being used, but the demand for Organophosphorus pesticides is increasing globally to control insects. Chlorpyrifos
is a broad-spectrum, highly toxic, and chlorinated organophosphate insecticide
that is synthetic in origin and is normally ester or thiol derivatives of phosphoric.
The mode of action involves inhibiting acetyl-cholinesterase, leading to the accumulation of acetylcholine, causing neurotoxicity. Bacteria capable of degrading
the pesticide chlorpyrifos were isolated from soil contaminated with pesticides.
This way, three distinct chlorpyrifos degrading strains of p.mendocina were isolated and characterized using morphological and biochemical analysis. Strains
exhibited the greatest chlorpyrifos degradation rate, reaching 100%, and were
consequently selected for further investigation. Degradation of chlorpyrifos by
strains was rapid at 20 and 37C. Bacteria species were able to effectively degrade
chlorpyrifos in the sterilized medium using high inoculum levels. The maximum
degradation rate of chlorpyrifos was calculated as 100% during 6-12 days. Bacteria such as strain PC1 that use chlorpyrifos as a carbon source could be employed
for the biodegradation of sites contaminated with pesticides

Published: August 2023

Bee venom BV draws attention in the medical field to manage several diseases,
including type 2 diabetes mellitus (T2DM). Due to limited research on this field in
Iraq, the study aimed to detect BV's histological and anti-oxidant impact in diabetic
mice. Fifteen male mice were randomly assigned into three groups. The first group
is control (C), the second is diabetic, and the last group is BV. At the end of 30
days, the obtained serum was used to measure the level of glucose, insulin, superoxide dismutase (SOD), and malondialdehyde (MDA). Furthermore, the pancreas
was histologically assessed using the Gomori stain. Alloxan showed significant
elevation and reduction in the level of glucose and insulin compared to the control.
These alterations were positively enhanced by BV. BV promoted significant elevation in the activity of SOD and suppressed MDA compared to diabetic mice.
Histologically, diabetic mice pancreas displayed a reduction of capsular tissue, islets and beta cells vacuolization, beta cells initial degeneration, reduction in the
shape and size of the islets and beta cells, and vascular hemorrhage. These changes
were remarkably enhanced nearly to normal by BV. Therefore, BV could control
the diabetic condition, which may be considered a potential anti-diabetic agent.

Effectiveness of Social Virtual Reality Training in Enhancing Social Interaction Skills in Children With Attention-Deficit/Hyperactivity Disorder: Protocol for a Three-Arm Pilot Randomized Controlled Trial
Authors: Wong Ka Po , Qin Jing
Published: August 2023

Background

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders among children. Children with ADHD have challenges in understanding social cues and behavioral problems when entering a social setting. Virtual reality (VR) has been applied to improve cognitive behaviors in children with ADHD. Previous studies have not adopted VR to improve social interaction competence and appropriateness in children with ADHD. VR offers a more effective alternative to therapeutic strategies for children with ADHD.

Objective

This study aims to examine the feasibility and effectiveness of social VR training in enhancing social interaction skills compared to traditional social skills training in children with ADHD. We hypothesize that participants in the social VR training group are likely to perform better on social interaction skills than those in the traditional social skills training group.

Methods

In this nonblinded, 3-arm randomized controlled trial (RCT), 90 participants with ADHD recruited from the community will be randomized 1:1:1 to the social VR intervention group, traditional social skills training group, or waitlist control group. The child psychiatrist will conduct assessments for each participant at baseline and after the intervention. The Social Skills Rating Scale–Parent will be used to assess the social interaction skills of the participants before and after the intervention. Participants in the social VR intervention group and traditional social skills training group will receive twelve 20-minute training sessions for 3 weeks. The participants in the waitlist control group will receive no training. The primary outcome measure is training acceptability and compliance. The secondary outcome measures are the child psychiatrist's assessment and the Social Skills Rating Scale–Parent before and after the intervention. Another outcome measure is the Behavior Rating Inventory of Executive Function and Attention. Differences in the scale scores will be examined using a t test and an F test.

Results

This study is set to commence in the fourth quarter of 2023. It is anticipated that participants in the social VR intervention group will exhibit superior social interaction skills than those in the traditional social skills training group.

Conclusions

To our knowledge, this RCT is the first study examining the feasibility and effectiveness of a social VR-based intervention for enhancing the social interaction skills of children with ADHD in Hong Kong. The VR-based social skills training is expected to provide a safer and more effective environment for children with ADHD to learn than the traditional approach. This study can lead to a full-scale RCT.

Authors: Correia Jorge César , Ahmad Sarmad Shaharyar , Waqas Ahmed , Meraj Hafsa , Pataky Zoltan
Published: August 2023

BACKGROUND

Obesity is a chronic, multifactorial, and relapsing disease, affecting people of all ages worldwide, and is directly related to multiple complications. Understanding public attitudes and perceptions toward obesity is essential for developing effective health policies, prevention strategies, and treatment approaches.

OBJECTIVE

This study investigated the sentiments of the general public, celebrities, and important organizations regarding obesity using social media data, specifically from Twitter (subsequently rebranded as X).

METHODS

The study analyzes a dataset of 53,414 tweets related to obesity posted on Twitter during the COVID-19 pandemic, from April 2019 to December 2022. Sentiment analysis was performed using the XLM-RoBERTa-base model, and topic modeling was conducted using the BERTopic library.

RESULTS

The analysis revealed that tweets regarding obesity were predominantly negative. Spikes in Twitter activity correlated with significant political events, such as the exchange of obesity-related comments between US politicians and criticism of the United Kingdom’s obesity campaign. Topic modeling identified 243 clusters representing various obesity-related topics, such as childhood obesity; the US President’s obesity struggle; COVID-19 vaccinations; the UK government’s obesity campaign; body shaming; racism and high obesity rates among Black American people; smoking, substance abuse, and alcohol consumption among people with obesity; environmental risk factors; and surgical treatments.

CONCLUSIONS

Twitter serves as a valuable source for understanding obesity-related sentiments and attitudes among the public, celebrities, and influential organizations. Sentiments regarding obesity were predominantly negative. Negative portrayals of obesity by influential politicians and celebrities were shown to contribute to negative public sentiments, which can have adverse effects on public health. It is essential for public figures to be mindful of their impact on public opinion and the potential consequences of their statements.

Published: August 2023

BACKGROUND

The relationship between educational outcomes and the use of online clinical knowledge support systems in teaching hospitals remains unknown in Japan. A previous study in this regard could have been affected by recall bias because of using a self-reported questionnaire survey.

OBJECTIVE

Therefore, we aimed to explore the relationship between the use of the UpToDate clinical knowledge support system in teaching hospitals and residents’ General Medicine In-Training Examination (GM-ITE) scores. In this study, we objectively evaluated the relationship between the total number of hospital usage logs in UpToDate and the GM-ITE scores.

METHODS

This nationwide cross-sectional study included postgraduate year 1–2 residents who had taken the examination in the academic year 2020. Hospital-level information was obtained from published WEB pages, and hospital usage logs of UpToDate were provided by Wolters Kluwer. We evaluated the relationship between the total number of hospital usage logs in UpToDate and residents’ GM-ITE scores. We analyzed 215 teaching hospitals with at least five GM-ITE examinees and hospital usage logs from 2017 to 2019.

RESULTS

The study population consisted of 3,013 residents (39.2%) from 215 teaching hospitals (36.2%) with at least five GM-ITE examinees and online resource usage log data from 2017 to 2019. High-use hospital residents had significantly higher GM-ITE scores than low-use hospital residents (26.9 ± 2.0 vs. 26.2 ± 2.3, p=0.009, Cohen’s d, 0.35; 95% confidence interval, 0.08–0.62). The GM-ITE score was significantly correlated with the total number of hospital usage logs (Pearson’s r=0.28, p < 0.001). Multi-level analysis revealed a positive association between the total logs divided by the number of hospital physicians and the GM-ITE score (estimated coefficient, 0.36; 95% confidence interval, 0.14–0.59; p = 0.001).

CONCLUSIONS

The findings suggest that that the development of residents' clinical reasoning abilities through UpToDate is associated with high GM-ITE scores. Thus, the higher use of UpToDate may lead physicians and residents in high-use hospitals to increase the implementation of evidence-based medicine, advancing educational outcomes.
Evaluation of Engineering Geological Conditions for Slope Stability Analysis of Diversion Tunnel Portal of Jlantah Dam, Karanganyar, Central Java
Authors: Ismanda Yayi , Indrawan I Gde Budi , Hendrayana Heru
Published: August 2023

This paper presents the research results carried out to analyze the slope stability of the diversion tunnel portal of Jlantah Dam based on the quality of the rock mass. The classification of the rock mass quality at the tunnel location refers to the Geological Strength Index (GSI) method while the analysis of portal slope stability is modelled numerically with the element method using Phase2 software. The modelling of the tunnel portal slope design with and without earthquake load was carried out to obtain the safety factor (SF) value. The results showed that the study area consists of residual soil, andesite breccia and lapilli tuff rocks with rock mass quality based on the GSI value ranging from poor to fair. The inlet portal slope is composed of rocks that have poor and fair mass quality while the inlet section is composed of rocks that have poor mass quality. The SF value>1.3 for conditions without earthquake effect was achieved on slope design 1V:1.5H and SF value>1.1 for conditions with earthquake effect was achieved on slope design 1V:2H. The SRF value at the portal outlet location is greater than the SRF value at the portal inlet location for the same slope design conditions indicating that the rock mass quality at the portal outlet location is better than the rock mass quality at the portal inlet location.

Published: August 2023

This work evaluated the possibility of generating electricity from flared gases through the application of combined power cycle (Organic Rankine and Brayton circle) which was simulated using Aspen Hysys. The data for the stimulation was obtained from literature in terms of the process plant operating conditions. The results obtained from the simulation were presented in terms of material balance, energy balance, costing, sensitivity analysis and exergy analysis, which is otherwise known as energy availability. The major equipment in the plants were: pump, heat exchanger, compressor, combustion chamber (conversion reactor), and an expender modeled as a gas and steam turbine respectively in Aspen Hysys simulation. The condenser was modeled as a cooler. The material and balance results were in agreement with the principles of conservation of mass and energy for a stead state process. The costing of the plant in terms of total capital cost, total operating cost, total utility cost, equipment cost and total installation cost were: $16,762,100.00, $70,661,490.00, $4,745,230.00, $11,323,700.00 and $12,359,400.00 correspondingly. The sensitivity analysis results revealed that efficiency of the gas turbine increase with an increase in exhaust gas pressure (kPa), signifying that the efficiency increased from 81.5% to 85% when the exhaust gas pressure was raised from 100 kPa to 500 kPa. The efficiency of the steam turbine increased from 72.6% to 74.2% when the outlet pressure was raised from 100 kPa to 900 kPa. Finally, the exergy result for gas turbine in terms of total exergy inlet and outlet are 14187 kW and 3710 kW respectively. This indicates an exergy efficiency of 26.15% or 10,477 kW exergy destruction. Similarly, the exergy result for steam turbine in terms of total exergy inlet and outlet are 1,856 kW and 1,357 kW respectively. This indicates an exergy efficiency of 73.12% or 498kW exergy destruction

Muchos de los aspectos asociados a la evolución de los entornos virtuales de enseñanza y aprendizaje podemos situarlos en la zona de tensión entre la tradición didáctica y la necesidad de incorporar cambios metodológicos. Durante la pandemia por Covid-19, se han generado cambios sociales y culturales en cuanto a las posibilidades de acceso a la educación y formas de comunicación, construcción y gestión del conocimiento. Las instituciones educativas necesitan adaptarse a los escenarios de transformación digital, implementando modelos pedagógicos híbridos. Entendemos que la formación continua debe considerar nuevas formas de acercarse a los docentes para dar respuesta a la demanda formativa tomando en cuenta la experiencia, el contexto y el aprendizaje social, es decir, en colaboración con otros.

Este trabajo se elaboró en el marco de la una beca de iniciación en la investigación de alumnos de posgrado de Maestría en Educación en Entornos Virtuales, en el proyecto PI 29/b255, denominado “La formación de recursos humanos en escenarios de transformación digital”, radicado en el Instituto de Educación y Ciudadanía (IEC) UNPA-UACO. La investigación que se desarrolló buscó, conocer el estado inicial de las competencias digitales de los docentes de nivel primario. Para ello se elaboró un cuestionario basado en el DigCompEdu, que fue aplicado virtualmente a docentes de nivel primario de la Cuenca Carbonífera de Río Turbio, en la Patagonia Argentina. Los resultados obtenidos nos brindan información relevante para la elaboración de recomendaciones que orienten la conformación de una comunidad virtual de aprendizaje que permita ampliar dichas competencias y mejorar las prácticas docentes con propuestas pedagógicas mediante TIC.
Recursos Educativos Abiertos Inclusivos (REAI), prácticas educativas abiertas (PEA) en el nivel superior en entornos virtuales
Authors: Vittaz Natalia , Vilanova Gabriela , Varas Jorge
Published: August 2023

Debido a las condiciones y necesidades que se plantean en la actual sociedad del conocimiento, las instituciones educativas de nivel superior deben redefinir los procesos de enseñanza y aprendizaje. Como menciona Salinas (2004), las universidades necesitan involucrarse en procesos de cambio y de mejora de la calidad. Ello incluye promover procesos de innovación en prácticas docentes y de aprendizaje, apoyados por las tecnologías de la información y comunicación (TIC).

Se destaca el uso de los recursos educativos abiertos (REA) desde una perspectiva de inclusión educativa y accesibilidad en entornos virtuales en el ámbito de la educación superior. Es prioritario entender la inclusión tal y como lo menciona Cabero y Córdoba (2009), cuyo objetivo es el de la integración, ya que se centra en todos los alumnos y tiene como eje la transformación cultural, la organización educativa y la práctica docente.

En Argentina existen leyes que promueven la distribución de los recursos y el acceso a procesos educativos de calidad de manera equitativa con el fin de reducir la brecha digital (Silvio, 2006). Entendiendo la brecha digital tal como la define Cabero y Córdoba (2009), como aquella que manifiesta la diferenciación producida en términos de igualdad en el acceso a la información, conocimiento y educación, un ejemplo de ello es la Ley de Educación Nacional Nº 26.206/06.

La presente investigación se vincula a diversas líneas de investigación del Grupo de Innovación en Educación en Ambientes Virtuales de Aprendizaje (GIEAVA), tales como modelos pedagógicos, comunidades virtuales de práctica, competencias digitales, e-tutoría, evaluación. Este trabajo se desarrolla en el contexto de una beca de iniciación a la investigación de alumnos de posgrado, en el ámbito del proyecto de investigación 29b254 titulado “Integración de Sistemas de Gestión del Aprendizaje (LMS) y entornos de web social en la Educación Superior, del Instituto de Educación y Ciudadanía (IEC)” de la Universidad Nacional de la Patagonia Austral – Unidad Académica Caleta Olivia (UNPA UACO).

Se aborda como caso de estudio el Centro Educativo de Nivel Terciario (CENT Nº 35) Profesor Julián José Godoy de la provincia de Tierra del Fuego Antártida e Islas del Atlántico Sur, en la asignatura Semiótica y Comunicación de primer año de la carrera Técnico Superior en Diseño Gráfico. Se describen prácticas educativas basadas en la innovación en las prácticas docentes de carácter abierto (PEA) en el marco de las normativas nacionales e internacionales referidas al uso de las diversas tecnologías y de la aplicación de mecanismos de planificación y organización en las prácticas educativas.

Los metales pesados son de gran interés en química ambiental debido, principalmente, al impacto negativo que presentan dichos elementos no degradables en el medio ambiente.

La técnica espectroscópica de absorción atómica (AA) es una de las más utilizadas para la determinación de metales. En este contexto, nos enfocamos en la determinación cuantitativa de hierro (Fe), plomo (Pb) y zinc (Zn) haciendo uso del equipo Perkin Elmer AA200 y el software WinLab32. Se realizó la validación del método analítico utilizado, verificando los parámetros de linealidad y límite de detección, obteniendo para el Fe linealidad hasta 3 mg/l, para el Pb hasta 10 mg/l y para el Zn hasta 0,75 mg/l. Los límites de detección calculados fueron aproximadamente 8, 25 y 2 ppb; respectivamente. Se puede concluir que la técnica utilizada podría resultar factible para la determinación de estos metales pesados en aguas superficiales, colectoras pluviales y canales en la provincia de Santa Cruz, como así también para analizar contenido metálico en agua destinada al consumo humano, ya que los límites admisibles por la ley de evaluación de impacto ambiental de la provincia y el código alimentario argentino, son superiores a los obtenidos.
El Paisaje natural en las memorias de los pioneros de las estancias rurales del Noreste de Santa Cruz, su antropización y su utilización como recurso turístico
Authors: Musacchia Damián Rafael , Sampaoli Patricia
Published: August 2023

Este trabajo tiene como base las memorias y recuerdos de los pioneros de las estancias del noreste de la provincia de Santa Cruz y las producciones académicas obtenidas en dos décadas de trabajos de investigación del equipo donde se ha desarrollado la presente beca.

A través de distintas metodologías, incluidas entrevistas de historia oral, se ha buscado enlazar las formas de ver el paisaje natural prístino y solitario de comienzos del siglo XX, período de asentamiento de los primeros productores lanares, y relacionarlos con los actuales, que tienen una potencialidad turística.

De este modo, podrá ser posible desarrollar un concepto de cambio y antropización del paisaje en base a lo aportado en las entrevistas y los trabajos de relevamiento bibliográfico que llevaron a variadas producciones académicas del equipo que analiza ese mundo rural y las variaciones del patrimonio cultural y natural que llega al tiempo actual. El paisaje antrópico que va modificando geomorfológicamente el paisaje, también es un actor protagonista en su relación con el paisaje natural y cierra un circulo, cuyo núcleo comienza a partir del poblamiento de las estancias del noreste de la provincia.

Desde los resultados parciales aquí construidos será posible enriquecer los circuitos turísticos ya delimitados, atravesándoles una nueva mirada, aquella que evoque el recuerdo a través de historias personales y de la observación del paisaje, incluyendo los cambios en el mismo y su relación con la inmaterialidad del patrimonio cultural.

En esta propuesta se pretende abrir una puerta de trabajo y teorización en materias referidas a memorias, rescate, puesta en valor y turismo en base a las experiencias de investigación y sus producciones académicas.

Effects of inactivated Streptococcus iniae, Edwardsiella tarda, and Poly I:C on mRNA Expression Levels of CXCL-10 and CXCL-9 Genes in Japanese Flounder
Authors: Bahrioğlu Ergi , Kondo Hidehiro , Hırono Ikuo

The present study accomplished the successful cloning and sequencing of the JfCXCL9_L and JfCXCL10_L genes found in the spleen cDNA of the Japanese flounder (Paralichthys olivaceus). The tissue distribution of these two genes was determined before any stimuli administration at the zero-hour mark. The qRT-PCR analysis demonstrated that the expression of JfCXCL10_L closely mirrored that of IL1-β, displaying an upregulation following the application of Poly I:C (Viral mimic) and formalin-killed Edwardsiella tarda (Gram-Negative mimic), while showing a downregulation after the application of formalin-killed Streptococcus iniae (Gram-Positive mimic) treatment. These findings strongly suggest a role for JfCXCL10_L in the immune response to viral and gram-negative bacterial stimuli. Regarding JfCXCL9_L, mRNA levels were found to be significantly downregulated after FKCET and FKCSI treatments, though to varying extents. Interestingly, at specific time points, JfCXCL9_L levels were even lower compared to Poly I:C treatment. These intriguing findings shed valuable light on the roles of both JfCXCL9_L and JfCXCL10_L in potential functions of immune response mechanisms of the Japanese flounder'.

In clinical management of carbon monoxide (CO) poisoning, serum cardiac enzyme biomarkers and electrocardiogram (ECG) are both highly recommended emergency check-ups to evaluate myocardial injuries. Medical imaging – including head CT or MRI – are not routine for CO poisoning emergency management. We herein report on a comatose patient who was diagnosed with cerebral infarction secondary to 24 hours previous acute CO poisoning, warned by a typical cerebral-type T waves on ECG in advance, and confirmed by a head MRI. Fortunately, the patient made a full recovery based on a timely treatment with medications and hyperbaric oxygen (HBO2) therapy. We would like to propose that a vital, stable, conscious CO poisoning patient who remains a higher risk for hemorrhagic or ischemic stroke should be closely monitored for potential neurological abnormalities, and a continuous ECG monitoring should be reinforced throughout the treatment. A head MRI or CT is a priority in evaluating the secondary cerebral stroke and should be arranged immediately in the event of an abnormal ECG or if unusual new symptoms are apparent.
