Authors: Wang Jilong , Huo Tangbin , Li Peilun , Lu Wanqiao 
Published: December 2023

To study their feeding habits, Coregonus ussuriensis samples were collected seasonally in the Amur River, China. A total of 574 samples were collected, including 200 individuals with empty stomachs. The stomach contents of the remaining 374 samples were identified, counted, weighed, and analyzed. The results showed that the vacuity rate of Coregonus ussuriensis was 34.84% in total; the rates in summer and autumn were higher than in spring and winter. Prey items could be divided into three categories: fish, benthos, and mammals, with 62 taxonomic units. Of these, fish had the highest relative importance index (IRI), followed by benthos and mammals. Specifically, Exopalaemon modestus was the dominant species among the food species of Coregonus ussuriensis, and unidentified fish, Hydropsyche sp., Hemiculter leucisculus, Abbottina rivularis, and Saurogobio dabryi were important species. The average repletion index (RI, %) of Coregonus ussuriensis was highest in autumn (1.86), followed by winter (1.40), summer (1.26), and spring (1.02). The main food of Coregonus ussuriensis was benthos in spring and autumn, and fish in summer and winter. Cluster analysis showed that, according to the similarity level of the bait biological composition, the fork length group samples of Coregonus ussuriensis could be divided into three groups: 210–330 mm, 330–450 mm, and &gt;450 mm. The highest IRI% of feed organisms in these three groups of samples were fish (73.67%), benthos (75.12%), and benthos (94.46%), respectively. It can be observed that with the growth of the fork length of Coregonus ussuriensis, the importance of benthos in its diet increases. The results of an RDA analysis on the relationship between main bait organisms and various factors indicated that season, river level, river width, and fish size have a significant impact on bait organisms and a positive or negative impact on the quality scores of some bait species. This study filled the gap in biological research on the feeding ecology of Coregonus ussuriensis and laid a research foundation for ecological research on this species and its resource protection and aquaculture.

Relevance. The eruption of deciduous teeth is a distinct physiological process marked by local and systemic manifestations, along with alterations in oral microbiota in children.Research objective. A comparative clinical study evaluating the efficacy of different medications in managing localized symptoms during challenging deciduous teeth eruption, alongside an assessment of a homeopathic medicine's influence on oral microbiota in children (in vitro).Material and methods. The study encompassed 120 infants ranging from 5 months to 2 years old, randomized into three groups (40 individuals per group), all experiencing challenging deciduous teeth eruption. The research groups were assigned the following interventions: a homeopathic medicine, a dental gel containing an antiseptic and analgesic properties, and a dental gel infused with plant extracts. Clinical assessments of the children were performed using the E.M. Kuzmina index (2000), while concurrent evaluations of the oral microbiota were also conducted.Results. After the course of the medicinal homeopathic preparation, the condition of the gums, as per the E.M. Kuzmina index, indicated good oral hygiene, in contrast to medicinal preparations containing synthetic and plant-based antiseptics and anesthetics, which resulted in a satisfactory level of oral hygiene. Microbiological research indicated that the utilization of the investigated samples of the homeopathic medicine facilitated the creation of conditions fostering indirect competition of the stabilizing oral micro versus the pathogenic group of microorganisms.Conclusion. The clinical effectiveness of the homeopathic medicine for challenging deciduous teeth eruption was notably higher. A more substantial positive trend was observed in relation to the oral microbiota in children following the twice-daily application of the homeopathic medicine solution.

Authors: Pauluk Dorota 
Published: December 2023

RESEARCH OBJECTIVE: The purpose of this article is to show, based on UNICEF and UNHCR documents, the problems of migrant children that hinder/impede their inclusion in the education of the host community and to identify ways to deal with these problems.
THE RESEARCH PROBLEM AND METHODS: Using document analysis, I will answer the following questions: What threats are children on the move exposed to? What are the priority areas for action? How can they be protected and integrated into the new education system?
THE PROCESS OF ARGUMENTATION: The paper presents the causes and risks associated with migration for children, important concepts for educational practice, recommendations and proposed solutions
RESEARCH RESULTS: The documents show the risks faced by children on the move. Such children are often marginalized and stigmatized in host communities. Ensuring their well-being (meeting their psychological needs and respecting their rights) is a priority and a necessary condition for them to be able to start education. The discussion shows the importance of education in dealing with difficult conditions or in counteracting negative phenomena (discrimination, xenophobia). Education is treated as capital that is supposed to give these children a chance for a better future.
CONCLUSIONS, RECOMMENDATIONS AND APPLICABLE VALUE OF RESEARCH: The following conclusions can be drawn for practice from UNICEF and UNHCR documents: children on the move should have the same rights and opportunities for education as their peers in host com- munities; they need friendly and safe places to live, play and learn; children have resources and experiences that should be considered when organizing educational environments.

Published: December 2023

The government of Sri Lanka implemented a range of developmental interventions to eliminate poverty by enhancing agricultural productivity, income diversification and economic growth in rural areas. The "Divineguma" (Livelihood upliftment) program was one such massive-scale livelihood improvement program that had multiple interventions at different levels. The intermediaries who link the government and the beneficiaries are the field-level extension officers (EOs). The beneficiaries have severely criticized the field-level extension service, especially the assistance on agricultural interventions. This study was done to examine the roles of the field-level EOs and beneficiaries’ perceptions regarding the knowledge, skills, and personal qualities of the EOs in the implementation of this rural development program, with special relevance to home gardens. A survey study was carried out in the Elapata Divisional Secretary division in Ratnapura district with a sample size of 150 beneficiaries. Beneficiaries perceived that the EO’s were influential in the startup motives of the participants but in follow-up roles, which are the most important roles for the success of the home garden program, were not fulfilled by these EOs. The participants also perceived that the field-level EOs were not well prepared when communicating with the participants and always neglected the importance of feedback in the communication process and they were not fully committed to the activities related to the home garden program. This study reveals that policymakers should constantly review the performance of the EOs and assess their training requirements.

Published: December 2023

Мета. З’ясувати перспективність використання рослин виду G. biloba та його сортів у техніках китайсько-японського садового топіарного мистецтва бонсай та нівакі. Методи. Дослідження виконували методами теоретичного аналізу, систематизації, порівняння й узагальнення літературних даних, а також користуючись власними методичними напрацюваннями. Результати. З’ясовано, що рослини G. biloba здатні продукувати химерні, схожі на коріння структури: повітряні та базальні чичі. Виділяють три різні стилі ґінкго-бонсаю: стиль «чичі», утворюваний унаслідок розмноження відсадками з дерев, які вже мали сформовані чичі; стиль «сталактит», отримуваний з повітряних чичі зі старих дерев і садіння їх з перевертом (долішньою частиною догори); стиль «грудка або брила», отримуваний відокремленням від базального чичі або внаслідок вторинного проростання базальних чичі з формуванням багатостовбурних ґінкго-бонсай у вигляді «лісу». Залежно від особливостей розвитку G. biloba, розрізняють звичайний ґінкго-бонсай — виконуваний у класичному прямостоячому стилі «Текан»; у стилі «Моєгі», характерними ознаками якого є «вигнута» або «звивиста» форми стовбура; у стилі «Сокан», що характеризується наявністю двох стовбурів, які можуть бути різними за розміром однак утворювати одну спільну крону, та ін., а також ґінкго-чичі бонсай. Для створення некласичних стилів нівакі G. biloba розроблено техніку плетіння стовбура косичкою та по колу. Висновки. Розглянуто особливості використання G. biloba у мистецтві бонсай, залежно від біологічних характеристик рослини. Описані особливості формування повітряних і базальних чичі G. biloba та їхня роль у створенні різних стилів бонсаю. Показано, що рослини G. biloba є перспективними для використання у техніках китайсько-японського садового топіарного мистецтва бонсай та нівакі.
