With the rapid advancement of educational technology, recent studies have connected teachers' professional noticing with the use of digital resources in mathematical instructions. In this study, I examined elementary mathematics preservice teachers' attending and interpreting a mathematical software, ST Math, in the exploring and implementing phases. The findings indicate that preservice teachers paid attention to visual representations and manipulation prior to interactions with children and further took into consideration on task structures and situated context after interactions. They interpreted the events based on connected mathematical knowledge of prior interactions and further reflected on the progression of problem-solving strategies and sequence of tasks. In addition, four distinctive profiles of transitioning of evaluation on ST Math activities were identified with illustrations. Implications for noticing and teacher education were discussed.

Though information exists regarding the pathogenesis of the shot-hole disease (SH) in flowering cherry (FC), there has been a lack of research focusing on SH management. Therefore, here, we investigated the inhibitory activities of antagonistic bacteria against SH pathogens both in vitro and in vivo as well as their biochemical characteristics and bioactive compounds. Two biosurfactant-producing bacterial antagonists, identified as Bacillus velezensis strains JCK-1618 and JCK-1696, exhibited the best effects against the growth of both bacterial and fungal SH pathogens in vitro through their cell-free culture filtrates (CFCFs). These two strains also strongly inhibited the growth of the pathogens via the action of their antimicrobial diffusible compounds and antimicrobial volatile organic compounds (VOCs). Crude enzymes, solvent extracts, and biosurfactants of the two strains exhibited antimicrobial activities. Liquid chromatography/electrospray ionization time-of-flight mass spectrometric analysis of the partially purified active fractions revealed that the two antagonists produced three cyclic lipopeptides, including iturin A, fengycin A, and surfactin, and a polyketide, oxydifficidin. In a detached leaf assay, pre-treatment and co-treatment of FC leaves with the CFCFs led to a large reduction in the severity of the leaf spots caused by Epicoccum tobaicum and Bukholderia contaminans, respectively. In addition, the two antagonists produced indole-3-acetic acid, siderophore, and a series of hydrolytic enzymes, along with the formation of a substantial biofilm. To our knowledge, this is the first report of the antimicrobial activities of the diffusible compounds and VOCs of B. velezensis against the SH pathogens and their efficiency in the biocontrol of SH.

A significant number of cases of illness has been attributed to food consumption in restaurants, and as the number of meals eaten away from home continues to rise, the potential for large-scale, foodborne illness outbreaks will continue to increase. It is critical that hospitality and culinary arts students preparing for careers as professionals in foodservice establishments or restaurants have an appropriate understanding of food safety. The level of food safety knowledge was similar between hospitality and culinary arts students, and an analysis of 266 questionnaires indicated that specific areas, such as hand washing, cross contamination in refrigerator, reheating leftovers, refrigeration of cooked food within two hours, proper temperature of food storage, using of thermometers to monitor temperatures, proper egg handling, and possible food borne illness caused by fruits, should be the primary focus of educational resources. Student respondents showed a higher awareness level of responsibility in their roles for food safety, but more emphasis needs to be given to the correct understanding of food safety issues. Hospitality and culinary arts educators can use this precise information to develop food safety education materials and programs to assist in the prevention of foodborne illness and to knowledgeably educate their graduates about food safety.

With biomedical literature expanding so rapidly, there is an urgent need to discover and organize knowledge extracted from texts. Although factual databases contain crucial information the overwhelming amount of new knowledge remains in textual form (e.g. MEDLINE). In addition, new terms are constantly coined as the relationships linking new genes, drugs, proteins etc. As the size of biomedical literature is expanding, more systems are applying a variety of methods to automate the process of knowledge acquisition and management. In my talk, I focus on the project, GENIA, of our group at the University of Tokyo, the objective of which is to construct an information extraction system of protein - protein interaction from abstracts of MEDLINE. The talk includes (1) Techniques we use fDr named entity recognition (1-a) SOHMM (Self-organized HMM) (1-b) Maximum Entropy Model (1-c) Lexicon-based Recognizer (2) Treatment of term variants and acronym finders (3) Event extraction using a full parser (4) Linguistic resources for text mining (GENIA corpus) (4-a) Semantic Tags (4-b) Structural Annotations (4-c) Co-reference tags (4-d) GENIA ontology I will also talk about possible extension of our work that links the findings of molecular biology with clinical findings, and claim that textual based or conceptual based biology would be a viable alternative to system biology that tends to emphasize the role of simulation models in bioinformatics.

The purposes of this study were to develop STEAM teaching materials about 'world of small organisms' unit on elementary science education and to apply lesson using them for the 5th and 6th graders. Compared to other STEAM programs studied previously, the STEAM teaching materials of this study includes students' STEAM, teachers' guide, story-telling books and multimedia teaching aids consisted of practical resources to manage STEAM lessons. The whole program was designed from multidisciplinary integration to extradisciplinary integration through activities making creative products, meanwhile each period had discretionary S, T, E, A, M factors specifically. To examine the effects of integrated lesson on scientific knowledge, process skills, and affective domain, the study subjects were divided into two groups. The experimental group was composed of 69 individuals participated in STEAM lesson, while students of the control group were 67 individuals learned through general learning methods. The developed STEAM teaching materials affected significantly on scientific knowledge and affective domain of elementary school students, but process skills were not increased significantly. In the present study, therefore, the approach applying STEAM education could be suggested as alternative learning materials or supplementary teaching materials at the field of small organisms in elementary science sufficiently.

Research and national standards, such as the Next Generation Science Standards (NGSS) in the United States, promote the development and implementation of K-12 interdisciplinary curricula integrating the disciplines of science, technology, engineering, mathematics, and computer science (STEM+CS). However, little research has explored how teachers provide epistemic support in interdisciplinary contexts or the factors that inform teachers' epistemic support in STEM+CS activities. The goal of this paper is to articulate how interdisciplinary instruction complicates epistemic knowledge and resources needed for teachers' instructional decision-making. Toward these ends, this paper builds upon existing models of teachers' instructional decision-making in individual STEM+CS disciplines to highlight specific challenges and opportunities of interdisciplinary approaches on classroom epistemic supports. First, we offer considerations as to how teachers can provide epistemic support for students to engage in disciplinary practices across mathematics, science, engineering, and computer science. We then support these considerations using examples from our studies in elementary classrooms using integrated STEM+CS curriculum materials. We focus on an elementary school context, as elementary teachers necessarily integrate disciplines as part of their teaching practice when enacting NGSS-aligned curricula. Further, we argue that as STEM+CS interdisciplinary curricula in the form of NGSS-aligned, project-based units become more prevalent in elementary settings, careful attention and support needs to be given to help teachers not only engage their students in disciplinary practices across STEM+CS disciplines, but also to understand why and how these disciplinary practices should be used. Implications include recommendations for the design of professional learning experiences and curriculum materials.

Purpose: Curricula for surgical residents should include training in trauma care; however, such training is absent in many low income countries. At the largest surgical training institution in Ethiopia, a trauma training program was developed, integrated into the existing surgical curriculum, and implemented. This study was conducted to evaluate the trainees' response to the new program. Methods: Over a 5-month period, 35 first-year surgical residents participated in weekly trauma care training sessions. The program included journal clubs, practical sessions, didactic sessions, and case-based discussions. Six months after the conclusion of the training, changes in knowledge, attitude, and practices were evaluated through a self-report survey. Results: For knowledge-based items, the survey data revealed reported improvements in 83.8% to 96.8% of students. Furthermore, 90.3% to 93.5% of participants indicated improvements in practice, while 96.7% exhibited a change in attitude. Respondents reported that attending didactic courses improved their presentation skills and facilitated the acquisition of knowledge. They suggested the inclusion of additional practical sessions. Conclusions: Training structures that are simple to implement are crucial for residency programs with limited resources. Such programs can be developed using existing academic staff and can aid residents in delivering improved care to trauma patients.

Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.
