Objectives The purpose of this study is to investigate the development process of learner initiative(student agen-cy) and the cultivation of future creative convergence competency in creative problem solving class based on learner initiative(student agency) and to explore implications. Methods The qualitative data was collected from 15 weeks of class reflection, class project results, teacher inter-views, peer evaluation papers, etc. The amount of collected data was 683 sheets of A4 paper and line by line anal-ysis was used. In order to support and supplement qualitative research, quantitative data collection was also conducted. Based on the operational definition of future creative convergence talent competency by Park Hyun-hee and Kwak Min-jung (2023), future creative convergence measurement was conducted before and after the 15-week class using questions suitable for this study through expert validity.The collected quantitative data were analyzed using the Spss 21 statistical program. Results As a result of qualitative data analysis, it was categorized into three core themes ⁇ understanding and demonstrating learner initiative, practicing communication and cooperation, and ⁇⁇recognizing continuous re-flection as a lifelong learner.As a result of quantitative data analysis, it was verified that the future creative con-vergence ability of college students who applied for the creative problem solving ability course based on learner initiative was cultivated. Conclusions The implications of this study are that the creativity problem solving class based on the learner ini-tiative, which is the core educational capacity for the future, has a high level of convergence ability of future crea-tivity, which is related to the core theme, and it is confirmed that the class in which the learner initiative is culti-vated through the team project activity was performed.Through this, discussions on the results, implications of limitations of the study, and future research directions were suggested.

Enzyme activity test paper with high wet strength and anion adsorption properties fabricated from whole cationized softwood chemical fiber

Paper-based test film material is widely used in a variety of test instruments for different applications. The enzyme activity test paper sheet is one of the most popularly used test papers. Here we present a novel fabrication of paper-based enzyme activity test paper without cationic resin added in. The chemical pulping fibers were first beaten to different degrees (from 14.6 to 41.5°SR) with a PFI beater. After that, the fibers were modified with a cationic agent (3-chloro-2-hydroxypropyl trimethyl ammonium chloride) under the system of alkali and water solution. Finally, the test papers were made with the modified fiber by a regular paper former in lab. The results showed that beating is beneficial for the improvement of the cationization reaction which is indicated by the Zeta potential, FTIR and EDS. The main mechanisms involved are the destruction of crystalline zone, increase of free hydroxyl group and defibrillation. This hypothesis was supported by the SEM, XRD and fiber analyzer. Beating under the optimized condition, the wet strength and liquid absorbability of test paper can meet the application requirement, and the test results of enzyme activity are quite close to those of commercial test papers.

A Comprehensive View of Food Microbiota: Introducing FoodMicrobionet v5.

Amplicon-targeted metagenomics is now the standard approach for the study of the composition and dynamics of food microbial communities. Hundreds of papers on this subject have been published in scientific journals and the information is dispersed in a variety of sources, while raw sequences and their metadata are available in public repositories for some, but not all, of the published studies. A limited number of web resources and databases allow scientists to access this wealth of information but their level of annotation on studies and samples varies. Here, we report on the release of FoodMicrobionet v5, a comprehensive database of metataxonomic studies on bacterial and fungal communities of foods. The current version of the database includes 251 published studies (11 focusing on fungal microbiota, 230 on bacterial microbiota, and 10 providing data for both bacterial and fungal microbiota) and 14,035 samples with data on bacteria and 1114 samples with data on fungi. The new structure of the database is compatible with interactive apps and scripts developed for previous versions and allows scientists, R&D personnel in industries and regulators to access a wealth of information on food microbial communities.

Botany of Mt. Saramati and its Environs

The paper gives a brief account of botany of Mt. Saramati in Nagaland, India which represents the state's highest mountain peak (3841m), the remotest and the botanically unexplored area. A brief note on topography, geology, climate and vegetation together with a comprehensive analysis of the floristic compositions of the vegetation types and is followed by enumeration of the species of angiosperms and gymnosperms. Analysis of the species collected established the following five families as the richest ones on the basis of the number of the species. Orchidaceae (25), Poaceae (24), Asteraceae (17), Ericaceae (13), Cyperaceae (9). These together represent about 40% of the total number of species collected. All the species recorded in this paper, except Deyeuxia pulchella (Griseb.) Hook. f. (Poaceae) are new additions to the Kanjilal's Herbarium (ASSAM) from the area. There is also no record of any representation of plant species from there by Clarke (1886, 1889), Hooker (1872-97), Kanjilal et al. (1934-40), Bor (1942), Jamir and Rao (1088). The present paper, therefore, represents the first source of information regarding botany of the Mt. Saramati.

Asclepiadaceae of Maharashtra

Family Asclepiadaceae is represented by 250 genera and ca 3000 species mainly distributed in tropical and subtropical regions of the world. It is represented by 43 genera and ca 243 species in India, of which, 31 genera, 82 species, 2 subspecies and 7 varieties are known from the State of Maharashtra. The family is well known for endemism, most elaborate complicated flower of all the dicots and contrivances for pollination. Most of the members of the family are restricted in distribution and many of them fall under some IUCN categories of rare plants. Many of the species are not available for taxonomic studies due to rarity of plant materials. Similarly fleshy nature of flowers makes it difficult to study floral structure in dried herbarium specimens. During last decade, deliberate attempts were made to collect asclepiads of Maharashtra and study their characters in fresh and prickled liquid preserved materials. During 10 years intensive survey of asclepiads of Maharashtra, about 63 species of the total 82 species reported for the State have been collected, documented, photographed, studied and reported in the present paper. The genus Ceropegia alone accounts for 24 species and 2 varieties for the state. Photographs of asclepiad flowers are found to be of paramount value in easy identifications than their descriptions. The paper gives an account of Asclepiads of Maharashtra, their distribution and present field status.

A comparative study assessing the validity of water absorption methods when applied to secondary fine aggregates

The valorization of secondary sands is crucial for fostering a circular economy within the construction sector. One significant obstacle in this endeavor stems from the high water absorption (WA) rates commonly reported for secondary sands. This high WA leads to increased water and cement demand in cementitious mixes and elevates costs. The only widely standardized method to measure the WA of fine aggregates is the cone method, which has proven ill-suited for fine aggregates with angular particles or a high content of fines. This study undertakes a comparative evaluation of the cone method and seven alternative methods: immersion, centrifugation, paper sheet, colorimetric, volumetric flask, continuous drying, and electrical conductivity. Tests were performed on natural river sand and three types of secondary sand. Findings reveal that the continuous drying and electrical conductivity methods demonstrates the greatest potential in terms of reliability and applicability. Also the volumetric flask and centrifugation methods show some potential, provided that critical refinements are made to the corresponding test protocols.
