The recent emergence of innovative learning spaces, Future Classroom Lab (FCL), provides educators the use of physical learning spaces (to research, interact, exchange, develop, create, and present) and diverse technological tools to work according to active methodologies. Learners become more active in the learning process with the introduction of innovative learning environments that enable the application of interdisciplinary STEAM methodology and foster the development of 21st century competences. This study aims to uncover the probable link between application active and gamified STEAM educational interventions in the FCL and Pre-Service Teachers' (PSTs) affective domain.

Article Synopsis
  • This pilot study examined how the season and region affect the prevalence of Theileria orientalis and blood health in dairy cows in Korea.
  • A total of 365 healthy Holstein Friesian cows from various provinces were sampled during both warm (July-August) and cold (October-December) periods.
  • Results showed a 20.0% overall prevalence of T. orientalis, with significantly higher rates in southern regions (35.9%) and during warm seasons (43.0%), which were linked to lower red blood cell counts and other hematological issues in infected cows.

Caseous lymphadenitis (CLA) caused by is a chronic disease that affects goats. The Korean native goat (KNG) is the most popular goat breed raised in Korea. In this study, the distribution of CLA in the KNG population and the relevance of sex and age in disease development were determined.

During the last decade, there has been a strong emphasis on developing new instruction methodologies for the effective teaching of different contents. Here, it is important to teach Science, Technology, Engineering and Mathematics (STEM) education, specially, in scientific and mathematical concepts. In the context of active learning and gamification, educational Escape Room - Breakout (ERB) could be a useful strategy to improve students' affective and cognitive domain towards STEM (science and mathematics).

Teaching mathematics in higher education has been followed traditionally by teacher-centered methodology. With this methodology, there are always certain difficulties in mathematics learning, revealing students are not capable of dealing properly with calculations and/or problems. This research presents the comparison and examination of two different instruction methodologies, traditional-classroom methodology (TCM) and flipped-classroom methodology (FCM) about self-belief of pre-service teacher (PST) in a mathematics course.

Due to the worldwide COVID-19 pandemic, university education has faced a significant challenge that requires adaptation to virtual and online education. Here, a fruitful flipped methodology with increased popularity can support adaption to and improvement of the current pandemic situation. This research presents a comparison of two different instruction situations with an identical teaching methodology, face-to-face (F2F) and face-to-screen (F2S) flipped methodology, in terms of students' performance and affective domain in a science, technology, engineering and mathematics (STEM) course.

KS1, a fastidious anaerobe, was isolated from a bovine digital dermatitis (BDD)-infected dairy cattle in Chungnam, Korea. Initial data indicated that KS1 exhibited putative virulent phenotypic characteristics. This study reports the whole genome assembly and annotation of KS1 (KCTC14157BP) to assist in the identification of putative pathogenicity related factors.

This study analyzed the diversity and phylogenetic relationship of the microbiome of bovine digital dermatitis (BDD) lesions and normal skin from cattle foot by using 16S rRNA amplicon sequencing. Three BDD samples and a normal skin sample were pre-assessed for analysis. The Illumina Miseq platform was used for sequencing and sequences were assembled and were categorized to operational taxonomic units (OTUs) based on similarity, then the core microbiome was visualized.

Sustainable development in education is growing a public awareness and is gaining an increasing importance to improve a long-term learning program. However, a higher sustainability education is an initial phase as ever in many universities. E-learning systems in science education based on innovative information and Information and Communication Technologies (ICTs) have close relationship in effective long-standing learnings of sustainability and numerous criteria.

Article Synopsis
  • This study analyzed the presence of Treponema bacteria in bovine digital dermatitis (BDD) lesions using PCR methods and high-throughput DNA sequencing.
  • A total of 29 BDD lesions from 25 South Korean dairy farms showed that Spirochaetes was the dominant phylum, with Treponema being the most prevalent genus, followed by Tenericutes and Bacteroidetes.
  • The research found that while Treponema species are the primary causative agents of BDD, other bacteria may contribute to the severity of the infection, indicating a complex interaction within the microbial community.

Destruction of extracellular matrix (ECM) leads to degeneration of the intervertebral disk (IVD), which is a major contributor to many spine disorders. IVD degeneration is induced by pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β), which are secreted by immune cells, including macrophages and neutrophils. The cytokines modulate ECM-modifying enzymes such as matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in human annulus fibrosus (AF) cells.

The aim of the present study is to investigate the learning-related changes in brain activation induced by the training of hypothesis generation skills regarding biological phenomena. Eighteen undergraduate participants were scanned twice with functional magnetic resonance imaging (fMRI) before and after training over a period of 2 months. The experimental group underwent eight biological hypothesis generation training programs, but the control group was not given any during the 2-month period.

Hypothesis generation has been regarded as one of the core reasoning processes in creative thinking and scientific discovery. To investigate changes in the amount of information transmission during scientific hypothesis generation, the averaged cross-mutual-information (A-CMI) of EEGs was estimated. Twenty-five 5th grade students were sampled in this study.

The purpose of the present study was to investigate differences in neural information transmission between gifted and normal children involved in scientific hypothesis generation. To investigate changes in the amount of information transmission, the children's averaged-cross mutual information (A-CMI) of EEGs was estimated during their generation of scientific hypotheses. We recorded EEG from 25 gifted and 25 age-matched normal children using 16 electrodes on each subject's scalp.
