Published: April 2024

El retraso académico constituye una problemática preocupante debido a las diversas consecuencias que produce. Los trabajos realizados en esta área han permitido identificar distintos factores que lo generan. También se ha estudiado variables de naturaleza “subjetiva” que inciden sobre este. Sin embargo, pese a que los programas universitarios que ofrecen apoyo al estudiantado apuestan a un fuerte componente afectivo y relacional, la experiencia emocional asociada al retraso aún es un campo poco abordado. El siguiente trabajo tuvo como objetivo conocer la experiencia emocional vivida ante el retraso académico. Se realizó un estudio cualitativo recurriendo a entrevistas semiestructuradas. Participaron 11 estudiantes de pedagogía de una universidad pública chilena. Se realizó un análisis cualitativo de contenido sobre los datos construidos. Los resultados apuntan hacia diferentes direcciones, tales como el impacto económico del retraso, el rol de contención de las y los compañeros, las influencias extraacadémicas en la génesis de esta situación, entre otros. Asimismo, el trabajo detalla diversos elementos utilizados para describir la experiencia emocional. Se construyeron cinco categorías, cuyos resultados fueron analizados en función de diversas aristas, considerando aspectos de orden conceptual y metodológico, hasta prácticos, como aquellos relacionados con la prevención e intervención de esta problemática.

Authors: Tong Xing , Wei Yemei
Published: April 2024

This study analyzed the mechanism of school autonomy on principals' organizational commitment by applying self-determination theory. Participants were 223 Chinese principals from primary and secondary schools. The survey results revealed that (a) school autonomy, job satisfaction, self-efficacy,
principal–teacher relationships, and organizational commitment were positively correlated with each other; (b) job satisfaction, self-efficacy, and principal–teacher relationships played multiple mediating roles between school autonomy and organizational commitment; and (c) the
respective strength of the three mediation effects was not significantly different. The findings enrich knowledge of school principals' organizational commitment and imply a need to pay attention to the satisfaction of their psychological needs.

Studies of microclimate parameters have shown the influence of microbial contamination on the productivity, growth and development of young pigs. It is known from the literature that exceeding the level of microbial contamination by 5 percent led to a decrease in the growth of piglets at weaning by 13.3 percent, in fattening pigs - to a decrease in live weight at slaughter by 3.7 percent. In addition, infectious diseases caused by pathogenic microorganisms affect the productivity of animals. For example, pneumogastroenteritis, transmitted aerogenically, affects from 30 to 95 percent of suckling piglets and weaning piglets. The damage caused by animal disease takes form of loss in productivity, death of sick animals and forced slaughter, as well as treatment costs. One of the promising and effective ways to clean the ventilation air in pig-breeding premises is the use of electrofiltration, including a wet electrofilter. There is little information in the scientific literature on the issues of disinfection of the air environment of pig-breeding premises from microbial contamination using electrofilters, which necessitates a more thorough consideration of this issue. (Research purpose) The research purpose is substantiating the prerequisites for the development of a methodology for determining the effectiveness of air disinfection with wet electrostatic filtering. (Materials and methods). The available studies on supply and exhaust ventilation systems and methods for determining the effectiveness of air purification by electrofilters from microorganisms were reviewed. Cited their shortcomings. (Results and discussion). It was found that wet electrostatic precipitators in the process of air purification generate ozone into the air, which is capable of destroying up to 95-99 percent of the population of dangerous microorganisms. It has been shown that by modernizing the air purification system in terms of improving the mechanisms for controlling ozone generation with a wet electrostatic precipitator, it is possible to improve the quality of the air environment by disinfecting the air with ozone. (Conclusions) It was determined that the effectiveness of cleaning the air of pig-breeding premises from microorganisms using wet electrostatic precipitators is relevant, further theoretical and experimental studies are needed.

To study the herbs drying process by solar energy using, a series of experiments on alfalfa in the third year of development were conducted. The site selection’s all requirements for crops’ placement and plots’ division with field experience methodology are consistence. To determine the drying regime’s effect on the alfalfa drying process kinetics, a series of experiments to effect of coolant humidity, its speed and temperature on the drying process studying were conducted. The experimental data analysis showed that the coolant’s temperature has the greatest influence on the herbs drying rate. At heliuoplant’s experimental studies’ course for drying herbs, influence degree of various indicators on the drying regime, alfalfa layer height, its grinding degree and the green mass’s initial moisture content on the drying process duration and alfalfa quality was determined. The drying duration, in depending on one factor at constant remaining of the other parameters was studied. Based on the analyses’ results, graphs of changes in the alfalfa’s carotene content in depending on the drying mode, green mass layer height and its granulometric state were constructed. It can be seen that at the coolant temperature decreasing, alfalfa quality is sharply decreased, that is not observed when the drying mode’s other parameters are changing, i. e. at the coolant change’s humidity and velocity, the carotene content is changed slightly. The best from the high quality feed’s obtaining point of view is drying alfalfa, crushed to a size of 0,03 m at a coolant temperature of 80 ...90°C. As a result of experimental data’s mathematical processing, a formula of the herbs drying coefficient’s dependence on the process’s main parameters was obtained. A comparison of the experimental data and the data calculated using the formula showed that the discrepancy does not exceed 17%. A comparison of the theoretical calculations and experimental studies’ results using possibility at theoretical developments in the new drying plants design has shown.

Published: April 2024

Tourism livelihood has become an essential livelihood decision for people to get rid of poverty. Under the background of the internet era, it is of great significance to study how ethnic village farm households can participate in tourism livelihood with the help of information capacity. Applying the Resource Orchestration Theory and taking Guolan Yao Village in Jiangyong County of Hunan Province as an example, this paper uses binary logistic regression model and fuzzy set qualitative comparative analysis method to explore the mechanism of farm households’ information capacity affecting their tourism livelihood. The findings are as follows: Firstly, in addition to financial capital, other livelihood capital and information capacity have a significant impact on farm households’ participation in tourism livelihood. Secondly, when financial capital is lacking, farm households in ethnic villages with information capacity can unite with human capital, social capital, natural capital or physical capital to make up for the non-existent defect of financial capital and help realize tourism livelihood. Thirdly, when human capital is lacking, farm households in ethnic villages with information capacity can make up for the absence of human capital by combining natural capital, financial capital and social capital to help realize tourism livelihood.

Published: April 2024

With the dynamic and complex changes in the farmers’ living environment and the vigorous development of entrepreneurial activities worldwide, farmer entrepreneurship is experiencing rapid growth. However, whether farmer entrepreneurship enhances the welfare of farmers’ families demands further scrutiny. Utilizing data from the Chinese Family Tracking Survey and drawing on Amartya Sen’s capability approach, this article formulates a farmer family welfare evaluation index system to comprehensively assess the impact of farmer entrepreneurship on farmer families. The research findings reveal the following: (1) Entrepreneurship contributes to enhancing the welfare of farmer families, with entrepreneurial farmer families experiencing higher welfare levels than their non-entrepreneurial counterparts. (2) Farmer entrepreneurship falls short of delivering complete welfare improvements to farmers’ families. While various welfare conditions, such as family economics, social security, living conditions, and psychological conditions, have improved after starting a business, health welfare has seen a decline. (3) Farmland transfer significantly influences the process of farmer entrepreneurship, directly fostering the family welfare of entrepreneurial farmers. (4) Farmers’ entrepreneurial behavior yields greater welfare benefits for the new generation, farmers with higher education levels, and those situated in the central region. Building on these findings, this study proposes relevant improvement suggestions to offer robust support for policy considerations.

The Carers' Fall Concern Instrument (CFC-I) is a tool used to measure the level of concern caregivers have when caring for older people who may be at risk of falling. However, it has not been determined whether this tool is valid for use among caregivers of elderly persons in Malaysia. Therefore, this study aimed to translate and to establish the psychometric properties of the Malay version of the CFC-I for use among caregivers of elderly persons. The researchers used the "forward-backwards" procedure to translate the CFC-I into Malay and then conducted a pilot study to evaluate the feasibility of the translated version. The study included 86 caregivers of elderly persons who analysed the validity and reliability of the Malay version of the CFC-I. The results indicated that the content validity of the 16-item CFC-I Malay version was excellent, as evidenced by I-CVI and k* values is 1.0. Moreover, experts agreed that the items were relevant, as shown by S-CVI/Ave and S-CVI/UA values of 1.0. Concurrent validity was established by a strong, positive correlation between the total scores of the Malay and original English versions (r = 0.762, p < 0.001). The instrument's internal consistency was also high, with a Cronbach's alpha coefficient of 0.89. Overall, participants rated their understanding of the instructions and questions of the CFC-I Malay version as level 4 or 5 (agree or strongly agree). The mean inter-item correlation was 0.51, ranging from 0.18 to 0.79. In conclusion, the Malay version of the Carers' Fall Concern Instrument is a valid and reliable tool for evaluating the level of fall concern among caregivers of elderly persons in Malaysia. Healthcare professionals can use this instrument to strengthen fall prevention strategies for older people in the country.

Published: April 2024

Understanding engagement in therapy is crucial for all stakeholders seeking to enhance child abilities through parent participation. Collaboration among stakeholders, including parents, and service providers could significantly impact the development of best practices in paediatric rehabilitation. However, there is a lack of research on parent engagement among children with autism spectrum disorder (ASD), specifically in measuring how parents and children engage during therapy sessions. This study aimed to understand the engagement of parents of children with autism spectrum disorder in therapy sessions. The study used a survey questionnaire namely the Paediatric Rehabilitation Intervention Measure of Engagement-Parent Version (PRIME-P), to identify the level of engagement comprising of affective, cognitive, and behavioural aspects. The study also assessed the probable stress factors influencing parent engagement using the Parental Stress Scale (PSS). One hundred and two (102) parents participated in this study. The data was analyzed for descriptive statistics, a correlation between engagement and parental stress, and regression analysis to determine the best predictor of engagement. The results showed that the levels of affective, cognitive, and behavioural engagement were high and promising, corresponding with a low level of parental stress. The findings contribute to the understanding of parent engagement, highlighting the role of service providers such as occupational therapists (OTs) and special education (SPED) teachers reflecting the most effective intervention approaches for children with ASD.

pediatric patients with acute lymphoblastic leukemia (ALL), focusing on
steroid-induced ocular hypertension, cytomegalovirus (CMV) retinitis,
and fungal chorioretinitis. Methods: We performed a
retrospective study among pediatric patients with ALL during the period
from January 2013 to December 2022. The ocular manifestations,
complications, and patients’ condition were recorded and analyzed.
Results: This retrospective study analyzed 167 patients with
ALL diagnosed between 2013-2022. Ocular examinations (including
intraocular pressure and/or retinal evaluation) were performed for 114
patients. Among examined patients, 37% (32/87) developed
steroid-induced ocular hypertension with mean intraocular pressure
(IOP): 25.08 mmHg, 95% CI [24.11, 26.06] which demonstrated a
significant difference compared to the study’s population’s (18.94 mmHg,
95% CI [17.98,19.90]). One patient had unilateral cytomegalovirus
(CMV) retinitis, and three had fungal chorioretinitis.
Conclusion: This 10-year retrospective study highlights the
substantial occurrence of ocular hypertension, and infectious
chorioretinitis, emphasizing the importance of early ophthalmic
evaluation and prompt intervention for pediatric ALL patients. Further
prospective studies are needed to refine risk assessment and optimize
management strategies.

Background Ganglioneuroblastoma intermixed (GNBi) and ganglioneuroma
(GN) are benign subtypes of neuroblastic tumors. Primary observation has
become accepted management for some patients with surgical operative
strategies evolving to be less aggressive. Objectives Our study examines
evolving management in a UK cohort investigating natural history,
biology and clinical features of GN and ganglioneuroblastoma-intermixed
(GNBi) in those having observation or surgery. Methods Retrospective
review of histologically confirmed GN and GNBi managed over a 30 year
period. Clinical, pathological features, tumor dimensions, management
and outcomes are all recorded. Results A total of 259 patients were
identified (GN= 163, GNBi = 93, median age = 62 months). 201(78%) had
upfront surgery and 58 (22%) were actively observed. Of the 58 observed
- 21 (36%) later required surgery due to progressive tumour growth
(52%). Gross total resection was achieved in 79% of patients with a
19% complication rate. Presence of image defined risk factors and large
tumour size correlated with incomplete resection (p < 0.05 in
both). Forty-five index cases (39%) had change in pathology between
biopsy and surgery with 14 patients (12%) altered from ‘favourable‘ to
‘unfavourable’. Conclusion Our findings show surveillance alone may be
considered a safe approach. However, a significant number of index
patients may eventually require operative surgery with development of
symptoms. Extent of surgical resection did not impact overall survival
(OS); however it improved symptom(s) resolution.

Background. Surveillance programmes for influenza and other
respiratory pathogens are important to generate vaccine effectiveness
(VE) estimates and to inform vaccine composition. We aimed to explore
the feasibility and acceptability of home-based testing.
Methods In 3/9 provinces in South Africa, we established a
self-referral system for individuals aged ≥18 years with respiratory
symptoms of ≤10 days duration. Following electronic consent, swab
collection material was delivered to participants who also completed a
questionnaire including self-reported vaccination status. Swabs were
tested by PCR for influenza, respiratory syncytial virus (RSV) and
SARS-CoV-2. A test negative methodology was used to estimate influenza
VE. Results Of 1456 samples collected between 1 December 2021
and 31 August 2022, 73 (5%) tested positive for influenza, 38 (3%)
tested positive for RSV and 394 (27%) for SARS-CoV-2. We subtyped 55%
(40/73) of the influenza positive specimens; 16/40 (40%) were influenza
A (A(H1N1)pdm09; 10/40 (25%)A (H3N2)) and all 14/40(35%) influenza B
were B/Victoria. Only 20% (279/1451) of participants reported
influenza-like illness case definition symptoms of fever and cough.
Influenza vaccine coverage was 11% (157/1454). The overall influenza VE
was 26% (95% confidence interval, -73%;69%). Of the completed
acceptability questionnaires, 123/127 (97%) participants would make use
of the service again. 36% (46/127) of enrolled participants were
recruited through the testing centre’s webpage and 13% (17/127) through
social media. Conclusions Home-based swabbing was feasible and
acceptable. We were able to calculate an influenza VE, although a large
sample size and verification of vaccine status may improve the VE
estimate in the future.
Organelle Genome Utilities: a toolbox for better utilizing organelle genomic data
Authors: Wu Ping , Xue Ningning , Yang Jie , Zhang Qiang , Sun Yuzhe , Zhang Wen
Published: April 2024

Organelle genomes serve as crucial datasets for investigating the
genetics and evolution of plants and animals, genome diversity, and
species identification. To enhance the collection, analysis, and
visualization of such data, we have developed a novel open-source
software tool named Organelle Genome Utilities (OGU). The software
encompasses three modules designed to streamline the handling of
organelle genome data. The data collection module is dedicated to
retrieving, validating, and organizing sequence information. The
evaluation module assesses sequence variance using a range of methods,
including novel metrics termed stem and terminal phylogenetic diversity,
as well as observed resolution. The primer module could design universal
primers for downstream applications. Finally, a visualization pipeline
has been developed to present comprehensive insights into organelle
genomes across different lineages rather than focusing solely on
individual species. The performance, compatibility, and stability of OGU
have been rigorously evaluated through benchmarking with four datasets,
including one million mixed GenBank records, plastid genomic data from
the Lamiaceae family, mitochondrial data from rodents, and 308 plastid
genomes sourced from various angiosperm families. Based on software
capabilities, we have identified 30 plastid intergenic spacers that
exhibit a moderate evolutionary rate and offer practical utility
comparable to coding regions, which highlights the potential
applications of intergenic spacers in organelle genomes. We anticipate
that OGU will substantially enhance the efficient utilization of
organelle genomic data and broaden the prospects for related research
endeavors.

Background & Objective : Covid-19 caused insurmountable misery
to individuals and health systems and caused millions of infections and
deaths globally. The situation was not different in India. This study
based upon primary household survey generated evidence on the health
seeking behavior during COVID 19, OOPE (Out Of Pocket Expenditure) due
to COVID related hospital visits and how a federal unit under the India
union responded to the crisis. Methodology: The study collected
primary data from a representative sample of 3,584 households and 276
COVID-19 positive patients who received treatment in an institution or
hospital as in-patients were selected from four district of Odisha,
India. Descriptive statistics like mean, median and percentage were used
to present the findings of the study. Results: More than half
of the sample households faced difficulty in accessing health services
during the COVID and a majority of them had difficulty due to
non-availability of transport facility followed by closure of medical
facilities. Our findings further suggested that 53% of the households
in the first wave and 63% in the second wave did not pay any anything
out of their pocket for availing outpatient care services. For inpatient
care, 70% in the first wave and 62% in the second wave did not spend
anything from their pocket. It was also observed that a majority around
90% in the wave 1 and 74% in the wave 2 accessed public health
facilities for Covid related inpatient care. From among those incurred
any OOPE, the average OOPE for the outpatient visit was INR 2312 in the
wave 1 and INR 2694 in the wave 2. Similarly for the inpatient care, it
was Rs 21,045 in the wave 1 and Rs 1,09,335 in the wave 2.
Conclusion: Our findings offer crucial insights into the
health-seeking behavior of individuals and the difficulties experienced
by both COVID and non-COVID-19 patients during the pandemic. Moreover,
the findings suggested that the initiatives introduced by the state
government resulted in averting OOPE by many households. Learning from
managing large disasters experienced earlier, the state’s health
management strategies were unique which resulted in more individuals
accessed care from public health systems and incurred less OOPE.

Published: April 2024

In real-world games, players may face an uncertain environment where
fuzziness and randomness coexist. The main difficulty in dealing with games
involving fuzziness and randomness arises when comparing the payoffs. The
purpose of this paper is to introduce a new approach to deal with
constrained matrix games where the entries of the constraint matrices are
LR-fuzzy random variables. Our methodology is based on constructing a new
matrix game using the chance constraint method adapted to the
probability-possibility measures. First, a specific type of saddle point is
defined as an equilibrium solution. Then, conditions for the existence of
the proposed solution are established. Further, a technique based on
second-order programming for computing the saddle point is presented.
Finally, a numerical illustration of the approach is provided.

Objective: This study aimed to investigate the radiological features of the permanent canines and the treatment carried out to ensure their eruption relative to certain features involved in Dental Anomaly Patterns (DAP).
Material and Methods: The cross-sectional part of this retrospective register­-based study focused on 1,315 dental panoramic tomographs (DPTs) of children aged 8.5–10.5 years, while the longitudinal part involved information on the treatment provided for 1,269 canines after the DPTs and on their eruption into the oral cavity.
Results: The canines of the DAP children more often showed evidence of early treatment (p = 0.014), with girls having more frequently interceptive treatment (p = 0.004) and boys early headgear (p = 0.022). Delayed dental age was associated with early treatment (OR 3.29, 95% CI 1.08–9.99). Either no or clear overlapping of a canine with the lateral incisor occurred more often in the DAP children, whereas canine inclination did not differ between the groups. The root development stage of the canine was more often either beginning or well advanced in the DAP children.
Conclusions: The children with dental developmental abnormalities more often showed evidence of early treatment for the canines. Monitoring of the erupting canines after the first mixed stage is important to enable timely early treatment.

Digital learning (DL) in vocational education has become a crucial issue that continues to be developed for innovation, including in the automotive engineering department. However, the problem is related to the relevance of the competencies to be achieved in accordance with industry qualifications. In addition, the stages of DL have not been fully understood by various educational practitioners. This study aims to analyze the perceptions of industry and education practitioners regarding the implementation of DL in automotive engineering (DL-AE). Sixteen key informants were involved in data collection through semi-structured interview techniques. Qualitative data were analyzed thematically with the help of the NVivo 12 Plus Software. The findings in this study are classified into three main aspects, namely activities prior to DL-AE implementation (Pre-DL-AE implementation), activities during DL-AE implementation, and evaluation of the DL-AE program. However, the lack of accessibility tools and the lack of intensive monitoring during the DL-AE was an obstacle that had to be solved. During the implementation of DL-AE, roles and responsibilities are needed which include aspects of facilitating, guiding and teaching material according to the portion. Evaluations regarding adjustments or changes to methods and ensuring equitable accessibility are also special considerations in increasing the effectiveness and efficiency of DL-AE in the future. These results have important implications in the development of digital learning that takes into account the aspects found in this research.

Online learning has become popular globally in every field of education as a result of advances in information and communication technology despite the COVID-19 pandemic. Online learning can be done synchronously and asynchronously. Based on this explanation, the purpose of this study was to analyze and compare synchronous and asynchronous online learning on students' oral presentation skills. This research method is an experiment with a quasi-experimental design. Two classes were selected as the sample for this study using a purposive sampling technique. With the provisions of one class as experimental class 1 by treating students with asynchronous online learning, while the experimental class 2 learning is carried out synchronously online. The research instrument used was a performance test, in which students made oral presentations. Analysis of research data using SPSS with the stages of normality test, homogeneity test, and t test. The results of the study showed that there was a difference in the average student learning outcomes, namely oral presentation skills and synchronous and asynchronous online learning processes. Based on the average difference, it shows that students are better at making oral presentations when learning is carried out asynchronously. Based on the results of this research, it can be concluded that online learning can be used as an alternative for the learning process, especially asynchronously, especially in relation to oral presentations.

Education is undergoing a profound revolution in the current era of digital technology, primarily due to the implementation of Massive Open Online Courses (MOOCs). These courses have facilitated worldwide accessibility to education of exceptional quality, transcending geographical and institutional limitations. This study aims to evaluates the implementation of gamification in Massive Open Online Courses (MOOCs) to enhance students' intrinsic motivation and graduation rates. Facing the challenge of low graduation rates in MOOCs, this study designed and implemented a Gamified MOOC (GMOOC) platform using a new gamification framework, MARC. Through an experimental method, this study involved 101 students and collected data through a questionnaire based on the Instructional Materials Motivation Survey (IMMS) and ARCS Model. The data was analyzed using Structural Equation Modelling (SEM), and the results showed that all MARC variables have high reliability and positively impact students' intrinsic motivation, with the Autonomy variable having the most significant impact. This study underlines the importance of a gamification framework in enhancing motivation and graduation rates in MOOCs, as well as the importance of considering the correct design elements and gamification components in the development of MOOCs. This study provides significant implications for developing and implementing effective and engaging MOOCs.

Published: April 2024

Dehydration is a state of decreasing the amount of fluid in the body accompanied by increased heart rate. One of the treatments that must be done for dehydrated patients is to give infusions periodically, which must be supervised by medical personnel. However, controlling patient intravenous fluid drops in some hospitals or public health centres is still done manually. Based on this problem, a device can adjust the drip rate of intravenous fluids based on heart rate. This research made a prototype of controlling the drip rate of intravenous fluid based on heart rate using NodeMCU ESP8266 microcontroller, MAX30100 sensor for heart rate reading, optocoupler sensor for drip rate reading, and servo motor for roller clamp drive. From the test results, the system has been able to control the drip rate of infusion based on heart rate with a range of (80 – 89) bpm which has the number of infusion droplets (24 – 35) TPM and a range (90 – 99) bpm that has the number of drip infusions (36 – 47) TPM, then send the heart rate data and drip rate of the injection to the thing speak website every 15 seconds. Heart rate readings with MAX30100 sensors have an error of 2.51% and an accuracy of 97.49%. Meanwhile, the drip rate reading with the optocoupler sensor has an error of 0.83% and an accuracy of 99.17%.
