Published: October 2024

The study examined the effects of flipped classroom learning on perception in genetics concepts among secondary school students in Gusau, Zamfara State, Nigeria. The research design employed was quasi-experimental; specifically, pre-test, post test, non equivalent control group design. A sample of 279 SS 3 Biology students drawn using multistage sampling technique from 5,804 SS 3 students for 2020/2021 session from 29 senior secondary schools in Gusau Local Government Area, Zamfara State, Nigeria. Students’ Perception of Genetics Concepts Scale (SPGCS) was the instrument used in collecting data, as Pretest and Post-test. A reliability coefficient of 0.98 was found using Cronbach’s alpha. The data were analysed using mean, standard deviation and Independence Z-test at 0.05 level of significance. Results indicated that students taught using Flipped Classroom Learning possessed high level of perception in genetic concepts than those exposed to lecture method with significant difference in the mean perception scores. The findings equally indicated the insignificant difference between the perception of male and female students exposed to Flipped Classroom Learning. The study recommends among others that Biology teachers should be encouraged to use Flipped Classroom Learning as the main teaching strategy to improve students’ perception in genetics concepts in senior secondary schools. Similarly, Biology teachers should be trained by the Ministry of Education and other education agencies on effective procedures for implementing Flipped Classroom Learning for high level of perception in genetics concepts.

Authors: Rivera Carolina González , Guadarrama Xochipilli Delgado , Miranda Miriam Puebla , Velo Juan-Antonio Vázquez , Mejía Teresa Cuestas
Published: October 2024

Poroid hidradenoma (PH) is a rare benign neoplasm of eccrine origin, typically located within the dermis. It most commonly affects individuals in the sixth and seventh decades of life, though it can present at any age. The head, neck, and trunk are typical locations. This case report details a 26-year-old male with a large PH on the right hip, an atypical location. The lesion began as a small, painful nodule and progressively grew over 18 months. Initial treatment, suspected to be for an abscess, was unsuccessful. A dermatological evaluation revealed a 7 x 8 cm exophytic, ulcerated mass, and biopsy confirmed the diagnosis of PH. Histopathological analysis showed solid and cystic components, with poroid cells identified. Immunohistochemistry was positive for markers such as CEA, CK-7, and p63, which are consistent with this tumor type. Following the confirmed diagnosis, complete surgical excision was performed, and the patient remains asymptomatic with no signs of recurrence. Poroid hidradenoma is characterized by both poroid and cuticular cells, and although it is generally benign, malignant transformation has been reported in less than 1% of cases. Therefore, complete excision is recommended to reduce the risk of recurrence and malignancy. This case highlights the importance of early diagnosis and appropriate management of PH, including long-term follow-up to ensure the absence of recurrence.

Published: October 2024

Introduction

Managing chronic conditions such as endocrinology and diabetes requires consistent access to medications. Traditional methods of medication refill often involve in-person visits to healthcare providers or pharmacies, posing challenges for patients. Online medication refill services offer a promising solution to improve accessibility and convenience.

Methods

This is a digital-based solution using online medication refill services to enhance the management of endocrinology and diabetes medication refills. It examines the process of online medication refill, including patient registration, refill request submission, verification, provider input, processing, and pickup or delivery.

Results

Online medication refill services empower patients to easily request refills from the comfort of their homes, streamlining the refill process, and reducing walk-in pressure in clinics. The online medication refill with the option for home delivery option eliminates the need for patients to visit the hospital, further enhancing the patient experience. Before implementing the online medication refill solution, 26 patients will come to the clinic as walk-ins to request medication refills. The average waiting time for each patient is 45 minutes. Each provider will be interrupted for an average of 10 minutes to accommodate the request. The overall processing time required for each walk-in patient to submit the medication request is 1 hour on average. After implementing the online medication refill intervention, zero patients come to the clinic as walk-ins and hence, no interruption to the daily regular clinics. The overall processing time required for submitting the online medication request is now 2 minutes. These interventions promote medication adherence and patient engagement by facilitating access to medications and offering educational resources.

Conclusion

Online medication refill services represent a valuable tool in the comprehensive management of endocrinology and diabetes. They offer accessibility, convenience, and patient empowerment, potentially improving health outcomes and enhancing the overall patient experience.

Published: October 2024

A apneia obstrutiva do sono (AOS) é um distúrbio respiratório prevalente, caracterizado pela obstrução parcial ou total das vias aéreas durante o sono, resultando em fragmentação do sono e oxigenação inadequada. Associada a uma série de comorbidades, como hipertensão e doenças cardiovasculares, a AOS afeta significativamente a qualidade de vida dos pacientes. O tratamento padrão, com o uso de CPAP, apresenta alta taxa de abandono, o que justifica a necessidade de alternativas terapêuticas, principalmente cirúrgicas. Este estudo tem como objetivo revisar os avanços cirúrgicos no tratamento da AOS, com foco em técnicas como uvulopalatofaringoplastia (UPFP), avanço maxilomandibular e estimulação do nervo hipoglosso. A metodologia adotada foi uma revisão narrativa da literatura, abrangendo artigos publicados entre 2007 a 2024 nas bases de dados PubMed, SciELO e Google Scholar. A análise qualitativa dos estudos revelou que as cirurgias avançaram significativamente em termos de eficácia e segurança, sendo a estimulação do nervo hipoglosso uma alternativa promissora para pacientes que não toleram o CPAP. Embora os avanços maxilomandibulares e a UPFP também se mostrem eficazes, há variações nos resultados dependendo das características anatômicas individuais. Conclui-se que os avanços cirúrgicos oferecem uma alternativa importante para o tratamento da AOS, mas a escolha do procedimento deve ser personalizada para otimizar os resultados. A falta de acessibilidade e o custo elevado ainda são desafios a serem superados, e estudos comparativos são necessários para estabelecer diretrizes mais claras.

Effigy Mounds National Monument: Paleontological resource inventory (sensitive version)
Authors: Tweet Justin , Santucci Vincent , Santucci Vincent , Tweet Justin
Published: October 2024

Effigy Mounds National Monument (EFMO) in northeastern Iowa was proclaimed on October 25, 1949 to protect a significant concentration of Native American burial mounds, many of which were built in the shapes of animals such as bears. Many of these effigy mounds are found atop commanding bluffs flanking the Yellow River at its junction with the Mississippi River. The geology of the monument has not been a central interest in its history, but the rocks contain evidence of millions of years of shallow marine life from the early Paleozoic. Paleozoic fossils were first documented at what is now EFMO in the mid-19th century, with few other reports. This inventory is the first report to focus on the paleontological resources of EFMO, documenting the scope, significance, distribution, and management issues associated with these non-renewable resources. It is based around two field visits that took place in July and November 2023.
The bedrock geology exposed within EFMO includes several rock formations dating from between roughly 490 and 450 million years ago, from the end of the Cambrian into the Late Ordovician. These formations capture parts of two major cycles of marine transgression and regression, with a depositional hiatus between. These rocks were deposited in and near shallow continental seas, at a time when the Upper Midwest was at tropical latitudes south of the Equator. A variety of fossils have been observed in the Jordan Formation (late Cambrian age), Prairie du Chien Group (Early Ordovician), and Platteville Formation (Late Ordovician). Most of the fossils in the two older units are burrows and other trace fossils. The Platteville Formation includes fossils of a much broader array of life. More than two dozen distinct fossil forms, most identifiable to a genus, have been recognized from the Platteville Formation at EFMO. The fossils belong to a typical Platteville assemblage of horn corals, bryozoans, brachiopods, bivalves, nautiloids, gastropods, trilobites, ostracodes, crinoids, and others. Fossiliferous areas are uncommon in EFMO but predictable. EFMO also has a small Holocene record from Founders Pond that is useful for reconstructing the monument?s ecology during the time when the mounds were built.
In addition to the above, this report documents cultural associations with paleontological resources and the monument?s museum collections (including the extensive fossil collections of foundational figure Ellison Orr). Discussion and recommendations for research, interpretation, and paleontological resource management are included.

Impact of Imputation on Performance of Goodness-of-Fit Tests for the Logistic Panel Data Model
Authors: Otieno Opeyo Peter , Weihu Cheng , Makled Randa A.
Published: October 2024

Goodness-of-fit tests aim at discerning model misspecification and identifying a model which is poorly fitting a given data set. They are methods used to determine the suitability of the fitted model. The subject of assessment of goodness-of-fit in logistic regression model has attracted the attention of many scientists and researchers. Several methods for assessing how well observed data can fit into logistic regression models have been proposed and discussed where test statistics are functions of the observed data values and their corresponding estimated values after parameter estimation. Considering a correctly specified panel data model with balanced data set, the conditional maximum likelihood estimates of the parameters are less biased and the estimated response variable values are actually in the neighborhood of the observed values. Relative to the induced biases of the parameter estimates resulting from imputation of missing covariates, the performances of the goodness-of-fit tests may be misjudged. This study looks at the susceptibility of the goodness-of-fit tests for logistic panel data models with imputed covariates. Simulation results show that Bayesian imputation impacts less on the goodness-of-fit test statistics and therefore stands out as the better technique against other classical imputation methods. An increased proportion of missingness however appeared to reduce the confidence interval of the test statistics which in turn reduces the chances of adopting the model under study.

Authors: Muzanenhamo Tonderai Joseph , Tsvere Maria , Mubaya Chipo Plaxedes
Published: October 2024

Mobile applications have provided a new way for agricultural transformation. This is set to revolutionise the agriculture sector with easy access to vital agricultural information on weather, market trends, pest, and disease management, and best agriculture practices to enhance agricultural productivity and profitability. However, there is a dearth of studies on the adoption of mobile applications in agriculture. It was important for this study to understand the impact of farmers’ demographic characteristics on the adoption of mobile applications in small-scale commercial agriculture. The study applied the quantitative research approach, a sample size of 213 small-scale commercial farmers, a descriptive cross-sectional research design, and the structured household questionnaire survey instrument, purposive random and stratified sampling techniques to collect primary data. Data was analyzed using descriptive statistics. The findings of the study revealed a higher adoption rate of mobile applications among young farmers than old farmers. The study indicated that female small-scale commercial farmers adopted mobile applications than male farmers. The study revealed that the majority of small-scale commercial farmers were literate. Further, the study highlighted that married farmers exhibited a greater tendency to adopt mobile applications than single, divorced, separated, and widowed. Furthermore, the study revealed that the majority of small-scale commercial farmers were engaged in agriculture as their primary occupation. The study argued that young farmers, female farmers, educated farmers, married farmers, and farming as a primary occupation positively influenced the adoption of mobile phone applications for improved small-scale commercial agriculture. The study recommends that policymakers and implementers should consider socio-demographic characteristics as critical determinants of the adoption of mobile phone applications for improved small-scale commercial agriculture to tailor strategies that promote the adoption of mobile applications based on different farmer age groups

Artificial Neural Network-Based Hybrid Controller for Electric Vehicle Applications
Authors: Bodapati Rakesh Babu , Srinivas R. S. , Rao P. V. Ramana
Published: October 2024

Power management among different energy sources of electric vehicles (EV) is one of the complex issues during the transition from one to another. A specific control is modeled based on the current and speed range of the electric motor named as Measurement of Parameter-Based Controller (MPBC), which will play a key role during transition of energy sources as per the load requirement. Two bidirectional converters are utilized to control the pulse signals generated by the traditional controllers which are connected at the battery and Supercapacitors (SCap) ends, which are treated as passive sources of the system. The Controller's artificial neural network (ANN), fuzzy logic (FLC), and proportional-integral (PI) are utilized to generate the pulse signal to the switches present in the converters by load. Further, specific controller MPBC is combined with three controllers ANN/FLC/PI individually and obtained three separate hybrid controllers as per the proposed control technique. The MPBC+PI/FLC/ANN controller-based MATLAB/Simulink model was designed, and applied to the electric motor individually at different load conditions. This model considered three different power delivery states from the PV array and assessed the motor's performance under different load scenarios. Compare the three hybrid controllers' final results to find out which one is more effective than the others.
Comparing gastrointestinal dysfunction score and acute gastrointestinal injury grade for predicting short-term mortality in critically ill patients
Authors: Shen Chao , Wang Xi , Xiao Yi-Ying , Zhang Jia-Ying , Xia Guo-Lian , Jiang Rong-Lin
Published: October 2024

BACKGROUND

The prognosis of critically ill patients is closely linked to their gastrointestinal (GI) function. The acute GI injury (AGI) grading system, established in 2012, is extensively utilized to evaluate GI dysfunction and forecast outcomes in clinical settings. In 2021, the GI dysfunction score (GIDS) was developed, building on the AGI grading system, to enhance the accuracy of GI dysfunction severity assessment, improve prognostic predictions, reduce subjectivity, and increase reproducibility.

AIM

To compare the predictive capabilities of GIDS and the AGI grading system for 28-day mortality in critically ill patients.

METHODS

A retrospective study was conducted at the general intensive care unit (ICU) of a regional university hospital. All data were collected during the first week of ICU admission. The primary outcome was 28-day mortality. Multivariable logistic regression analyzed whether GIDS and AGI grade were independent risk factors for 28-day mortality. The predictive abilities of GIDS and AGI grade were compared using the receiver operating characteristic curve, with DeLong’s test assessing differences between the curves’ areas.

RESULTS

The incidence of AGI in the first week of ICU admission was 92.13%. There were 85 deaths (47.75%) within 28 days of ICU admission. There was no initial 24-hour difference in GIDS between the non-survival and survival groups. Both GIDS (OR 2.01, 95%CI: 1.25-3.24; P = 0.004) and AGI grade (OR 1.94, 95%CI: 1.12-3.38; P = 0.019) were independent predictors of 28-day mortality. No significant difference was found between the predictive accuracy of GIDS and AGI grade for 28-day mortality during the first week of ICU admission (Z = -0.26, P = 0.794).

CONCLUSION

GIDS within the first 24 hours was an unreliable predictor of 28-day mortality. The predictive accuracy for 28-day mortality from both systems during the first week was comparable.
Metabolic dysfunction-associated steatotic liver disease: The question of long-term high-normal alanine aminotransferase as a screening test
Authors: Moyana Terence N
Published: October 2024

The growing prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is being driven by the obesity epidemic. The quest for solutions continues particularly with regard to early detection. This editorial comments on the utility of long-term high-normal alanine aminotransferase (ALT) in screening for MASLD. Chen et al found that new onset MASLD can be detected by repetitively high normal ALT. Implicit in this concept is the question of what should be the accepted upper limit of normal (ULN) for ALT. It was previously set at 40 IU/L based on studies that included people with subclinical liver disease but the new consensus is 30/19 U/L in healthy males/females. Thus, when Chen et al defines the ULN as 40 U/L, others may view it as excessively high. It is important to recognize the variables affecting ULN e.g. instrumentation, diurnal variations, exercise and ageing. These variables matter when the distinctions are subtle e.g. normal vs high-normal. In this regard, the utility of long-term high normal ALT as a disease marker could be enhanced by combining it with other biomarkers, imaging and MASLD genetics to create machine learning classifiers. All in all, Chen et al ’s work on long-term high normal ALT as a marker of new-onset MASLD deserves merit.

Authors: Yang Jia-Chen , Chen Liu-Xiang , Hu Bing
Published: October 2024

Crawling-type gastric adenocarcinoma is a rare subtype of gastric cancer with diagnostic and therapeutic challenges due to its flat, ill-defined lesions. Advanced diagnostic techniques, such as narrow-band imaging and linear endoscopic ultrasonography, improve detection, but endoscopic submucosal dissection poses a risk of incomplete resection. Despite negative resection margins, vigilant postoperative monitoring is crucial due to the potential for recurrence. This letter highlights the importance of refined diagnostic criteria, individualized treatment approaches, and continuous follow-up to optimize management of this unique gastric cancer subtype.
Improving early diagnosis of multiple endocrine neoplasia type 1 by assessing the gastrointestinal symptoms, hypercalcemia, and elevated serum gastrin
Authors: Velikova Tsvetelina , Lazarov Velik
Published: October 2024

Despite advancements in the field, early diagnosis of multiple endocrine neoplasia type 1 (MEN1) remains unachievable. This letter to the editor highlighted the importance of carefully assessing gastrointestinal symptoms, hypercalcemia, and elevated serum gastrin levels, as suggested by Yuan et al in their paper. They focused on a patient with recurrent abdominal pain and diarrhea whose diagnostic path led to establishing a MEN1 diagnosis within a year. This emphasized the need for clinicians to consider MEN1 in patients with similar presentations, particularly when gastrointestinal symptoms persist or recur after discontinuation of proton pump inhibitors, especially knowing that early recognition and intervention are crucial for improving patient outcomes.

A Comparison of Boosting Performance by Learner
Authors:   The Korean Data Analysis Society, Kim Hojung , Cho HyungJun
Published: October 2024

Ensemble learning is a learning method that combines several models to create a model with strong performance, showing excellent performance in many fields of real life. Ensemble learning methods largely have boosting and bagging techniques, and the difference between these two methods arises from whether the learner is trained sequentially or independently. In most boosting methodologies, decision trees are used as learners to perform well, and there are papers comparing them. However, models other than decision trees can also be used as learners of boosting, thus in this paper, various learning methods were applied and the results were compared. Limited to the situation of binomial classification problems, the accuracy of boosting was compared by applying a generalized linear model, a support vector machine, a K-nearest neighbors, discriminant analysis, and an artificial neural network as learners. As a result, out of all six learning methodologies, boosting based on decision trees was the best, and boosting based on generalized linear models, K-nearest neighbors, and artificial neural networks generally showed good performance, and worst performance based on support vector machines and discriminant analysis.

The purpose of this study is to analyze the cost efficiency of Korean professional baseball(KBO) teams through Data Envelopment Analysis(DEA) and Stochastic Frontier Analysis(SFA) and to examine its determinants.. In this study, we used 20 years of data from 2003 to 2022 for eight teams to examine the cost efficiency and its influencing factors of each team through DEA window analysis and SFA reflecting the time series. The empirical results showed that the cost efficiency of KBO teams is not high, but it is generally improving. Among them, the size of the stadium and the number of wins have a positive effect on cost efficiency, while the number of new stadiums and free agents has a negative effect on cost efficiency. In particular, the difference between the efficiency values derived from the two methods is quite large, which means that it is highly sensitive to external shocks due to the probable error. The fact that many teams react greatly to external shocks suggests that the support of parent companies and local governments greatly affects the sustainability of the teams due to the lack of self-reliance of the teams. In order to increase the self-reliance of KBO teams facing a new competitive environment after COVID-19, continuous efforts are needed to transform into solid companies, including positive external support and cooperation with local governments, as well as creating higher-quality cultural content and discovering diverse sources of revenue.
Stock market returns and trading behavior of individual investors
Authors:   The Korean Data Analysis Society, Ko Kwangsoo
Published: October 2024

This study examines the relationship between individual investors and the KOSPI stock market using long-term data spanning 25 years from 1999 to 2023. However, this study analyzes the relationship between individual investors' net buys and KOSPI returns by dividing the entire period into five sun-periods of five years and applying two-sided regression and structural vector autoregressive (SVAR) models. The main findings are as follows: First, compared to foreign investors, both institutional and individual investors exhibit relatively higher turnover ratios. Second, cross-sectional analysis shows that KOSPI returns decrease monotonically with the individuals' net buys. Third, the results of the two-sided regressions indicate a Granger causality, where past returns negatively influence individual investors' net buys. In addition, today's individual net buys negatively Granger cause future returns. Fourth, the SVAR analysis also shows that KOSPI returns have a strong negative effect on individual net buys. Finally, according to the results of SVAR impulse response function, net buys response negatively to KOSPI shocks, and this response dissipates almost entirely by the third day. In summary, individual investors tend to engage in net selling in response to positive news in the KOSPI market, and this tendency may be a key reason for their lower performance.
The relationship between investors sentiment and stock liquidity
Authors:   The Korean Data Analysis Society, Lee Hyung Chul
Published: October 2024

This paper empirically investigates the relation of investors' sentiment and stock liquidity. Particularly, this research explores whether investors' sentiment is related to stock liquidity and whether the level of individual trading and information environment in each firm affects the relation. Three hypotheses were drawn and tested. To test the hypotheses, stock prices and relevant data of firms listed on Korea Exchange(KRX) were put together, and the hypotheses were studied by panel and Fama-MacBeth regressions. This research discovers that investor sentiment has positive effects on stock liquidity. Further, this study finds that the level of individual trading and the level of information environment increases the positive relation between investors' sentiment and stock liquidity. This work finds individual trading and information has a certain role in the relationship between investors sentiment and stock liquidity. The findings suggest that increased investor sentiment may cause noise trading to increase. In addition, firms with more uninformed trading may have a more liquid stock market.
Factors Affecting Clinical Competency for New Graduate Nurses
Authors:   The Korean Data Analysis Society, Kim Da Hye , Min Haeyoung
Published: October 2024

The purpose of this study was to examine the effects of new graduate nurses’ self-leadership, organizational socialization, and preceptors’ communication style on clinical competency in order to improve their clinical competency. A total of study subject were 123 nurses who had worked for less than 12 months of clinical experiences at an advanced general hospital in J city. The collected data were analyzed using frequency percentage, mean, standard deviation, independent t-test, one-way ANOVA, Pearson’s correlation coefficient, and stepwise multiple regression analysis by SPSS/WIN 27.0 program. There were no significant differences between new graduate nurses’ general characteristics and clinical competency(F=1.01, p=.390). The factors affecting new graduate nurse’s clinical competency were self-leadership (β=.59, p<.001), and organizational socialization-job satisfaction (β=.15, p=.046), explaining 45.1% of the variance (F=49.24, p<.001). Based on the results of this study, the effective education program is needed to enhance new graduate nurses’ positive self-leadership as well as to increase job satisfaction in order to better perform clinical competency.
Comparative Analysis of Performance by Skill Level and Score Prediction for Screen Golf Users
Authors:   The Korean Data Analysis Society, Chun Young Jin
Published: October 2024

This study aimed to analyze and compare various performance variables, such as hole-by-hole scores, putts, greens in regulation, and par save rates among screen golf users at different skill levels, to identify their characteristics and predict round scores based on these variables. To achieve this, images of 'screen golf score cards' were collected from an internet portal using the keyword, resulting in a total of 441 records. Performance variables, including putts per hole, greens in regulation, and par save rates, were input into an Excel program for calculation. The analysis revealed differences in performance variables such as hole-by-hole scores, total putts, occurrences of three-putts or more, greens in regulation, and par save rates across different skill levels. Specifically, greens in regulation was found to have the greatest impact on scores. The proportion of putts in scores did not differ between the under and single handicap groups, and differences in par save opportunities were not observed except in the double bogey group. Therefore, it is essential to focus on improving greens in regulation through accurate iron shots and developing the ability to finish with a one-putt even if greens are missed. Future research should consider including variables related to tee shots, such as driver distance and fairway accuracy.
The Impact of Resource Scarcity on Self-Efficacy: The Mediating Role of Perceived Control
Authors:   The Korean Data Analysis Society, Won Yunha , Hong Seok-sung , Kim Kyungil
Published: October 2024

This study aimed to test the mediating effect of perceived resource scarcity to determine whether perceived resource scarcity reduces one's sense of control over one's personal and personal life and whether this reduced sense of control has a negative effect on self-efficacy. Data were collected from 400 adults and the paths between perceived resource scarcity, perceived control, and self-efficacy were analysed. In addition, we conducted a confirmatory factor analysis(CFA) of the perceived resource scarcity scale and a one-way ANOVA to examine whether perceived resource scarcity differs across age groups. The results showed that the three factors of the perceived scarcity scale were confirmed and only material scarcity showed significant generational differences. In particular, among the three factors of perceived scarcity, psychological scarcity was significant with a partial mediation effect, material scarcity was significant only with a full mediation effect, and time scarcity was significant only with a direct effect. The significance of this study is that it not only examines the psychological impact of perceived resource scarcity, but also the mechanisms through which it reduces self-efficacy. Finally, limitations and future research directions are presented.
