Integrated learning at primary schools in Lithuania
Authors: Tandzegolskienė-Bielaglovė Ilona , Jakavonytė-Staškuvienė Daiva , Kaminskienė Lina 
Published: January 2024

The research on integrated learning in primary grades in Lithuania was based on the curriculum spider web concept proposed by Akker (2003, 2010). In discussing successful experience of integrated curriculum design, development and implementation, researchers emphasize the balance between the main components of the curriculum: 1. The rationale or vision; 2. Goals and objects; 3. Content; 4. Educational activities; 5. Teacher's role; 6. Materials and resources; 7. Grouping; 8. Place; 9. Time; 10. Assessment. When evaluating the experience of implementing integrated curriculum at schools, all ten components should be addressed in a coherent way, to understand where the challenges and problems of implementing integrated curriculum exist, as well as to identify the strengths of schools’ practices and to anticipate where changes and improvements are needed. The research aim was to reveal attitudes of primary school teachers towards integrated curriculum and barriers to the implementation of integrated education in primary education.
The study shows that a significant number of Lithuanian primary school teachers work in collaborative teams, and that educational practice is associated with the principle of fusion, which is developed at the school level through collaboration between practicing teachers, administrators, and researchers. Such areas as character education, citizenship, cooperation, communication, creativity, critical thinking, and skills are integrated into the curriculum.
The lack of teaching materials for the organization of integrated curriculum (especially in the case of multidisciplinary activity sets) poses a particular challenge for primary school teachers, which requires a significant increase in the amount of time for preparing learning activities. The results of the study show that teachers express concern that, if integrated learning dominates the subject-based curriculum, students will achieve lower academic results in national standardized tests. Practice of integrated learning in other countries shows that when students receive targeted individual support, and when they participate in peer learning with a systemic teacher guidance, they develop both their social skills and critical, creative thinking through project-based or experimental activities. This makes students more motivated, eager to learn in a positive learning environment, and they perform significantly better on tests and show better individual progress.

Resumo: A presente revisão objetivou analisar a produção científica acerca da violência contra a mulher com destaque para a forma de agressão, idade, etnia e classe social no período pré e pandêmico (Covid-19). As buscas pelos artigos foram realizadas no PubMed e na Biblioteca Virtual em Saúde (BVS), resultando em 62 artigos. Após a aplicação das estratégias de seleção, a amostra final foi composta por 16 artigos. Os principais resultados dos estudos foram agrupados de acordo com o tema principal, e os resultados indicaram que não há uma distribuição proporcional de publicações entre os últimos cinco anos, entre antes e durante a pandemia, a maioria dos estudos foram realizados antes da pandemia. Em relação à raça/cor a que prevaleceu foi a negra/parda, e a idade das vítimas que prevaleceu foi a faixa etária de 20 a 39 anos. Não houve equilíbrio entre os estudos quanto a abordagem, a maioria deles utilizou a abordagem quantitativa. Prevaleceu os estudos realizados por análise documental sendo poucos realizados com pesquisa de campo. A raça, nível de escolaridade, renda mensal, ocupação e estado civil são apontados como fatores que influenciaram no surgimento de violência contra mulher, destacando-se artigos referentes a violência contra mulheres por parceiro íntimo (VPI) antes da pandemia do Covid-19, e poucos artigos sobre violência contra mulheres no período de pandemia Covid-19. Novos estudos podem ser desenvolvidos sobre os casos de violência doméstica durante a pandemia, e fazer uma relação dos casos antes, durante e depois da pandemia.

Salmonellosis is a disease caused by Salmonella gallinarum, which can cause digestive tract infections. Probiotics are good microorganisms for the host because they can increase the normal bacteria flora in the digestive tract. They can maintain the intestinal mucosal barrier and prevent bacterial adhesion. This study aimed to determine the histomorphometric characteristics of the jejunum from the intestines of mice (Mus musculus) after being infected with S. gallinarum. A total of 20 mice, 4-6 weeks, were divided into four research groups: P1 (probiotics and S. gallinarum infection), P2 (probiotic administration), P3 (S. gallinarum infection), and P4 (control). The probiotics used contain microorganisms such as Lactobacillus casei, Saccharomyces cerevisiae, and Rhodopseudomonas palustris, dissolved in distilled water in a ratio of 1:1000. Probiotics were given orally at 0.5 ml for 7 days. S. gallinarum infection was given orally, with a volume of 0.5 ml (1.5 x 108 CFU/ml). The results showed that the mean score of intestinal lesions differed between groups. The width of the villi, the thickness of the mucosa, and the depth of the intestinal crypts were significantly different. The best result of histology findings was in the group of mice that were induced with probiotics (P2).

The poultry industry is crucial in meeting the population's nutritional needs worldwide. However, various bacterial infections have been reported in poultry chickens, decreasing their production rate. Farmers have been using synthetic antibiotic agents to manage these infections, which are costly and have several side effects. One of the most commonly reported bacterial pathogens is Salmonella enteritidis, which causes high mortality and low poultry production. Mortality and illness rates are associated with gastrointestinal diseases caused by suboptimal absorption. This study was conducted to evaluate the anti-inflammatory and antioxidant effect of Chlorogenic acid (CGA) from robusta lampung green coffee extract on S. enteritidis infected chickens. ISA brown day-old layer chickens were used in this study. A total of sixty chickens were divided into five groups, with each group having 12 replications. The formulated groups were C+ (chicken infected by S. enteritidis 108 CFU/ml), C- (healthy chicken), T1 (chicken infected by S. enteritidis 108 CFU/ml and 500 mg/kg BW (bodyweight) coffee extract), T2 (chicken infected by S. enteritidis 108 CFU/ml and 1000 mg/kg BW coffee extract), T3 (chicken infected by S. enteritidis 108 CFU/ml and 1500 mg/kg BW coffee extract). The Nrf2, HO-1, and SOD levels were measured using BD cell quest ProT programmed through the flow cytometry method. Data of total cells were calculated for their average value and obtained data were statistically analyzed by One Way ANOVA (p<0,5). The results of the study showed that giving coffee extract at a dosage of 500 mg/kg BW to S. enteritidis infected chickens increased the Nrf2 and SOD levels but decreased HO levels. This research showed that Lampung robusta coffee extract could potentially be an anti-inflammatory compound and antioxidant for poultry industries.
Political Risk in Latin America

Published: January 2024

Abstract
Political risk (PR) is a fascinating concept in the political science literature, yet researchers could do more to evaluate PR in Latin America. In this paper, we contribute to filling the gap by presenting the risks investors must consider when building portfolios in developing economies, such as changes in economic policy or impeachment processes. As for the methodology, widely accepted statistical methods are used to test our hypotheses as well as reliable data. Regarding our findings, we discovered that political color determines economic policy (to a certain degree) and that macroeconomic consequences vary based on policy. In addition, we indicate the adverse effects that specific economic policies and impeachment processes have on Latin American stock markets. In conclusion, this research proposed to advance the political science literature and finance interception, and it does it by motivating the discussions.

Published: January 2024

Malocclusion is a manifestation of the interplay between genetic and environmental variables on the development of the orofacial region, whereas growth is the cumulative effect of numerous environmental and genetic variables over time. When diagnosing orthodontic problems hereditary variables should be taken into account in order to identify the root of the problem, as this may also impact how orthodontic therapy turns out in the end. Treatment options for malocclusions resulting from genetic causes are generally considered to be less effective than those resulting from environmental factors. The likelihood of a good orthodontic intervention outcome decreases with increasing hereditary component. A clinician's capacity to treat malocclusions effectively would be substantially improved by understanding the different effects of inherited and environmental variables.When diagnosing almost all dentofacial anomalies, orthodontists may be concerned with genetics to learn more about the reasons behind a patient's specific occlusion. Genetic variables are a crucial component of treatment.

To evaluate the smile esthetic perception on varying gingival display and black triangles among individuals aged between 18-35 and 36-50 using a visual analog scale (VAS). To evaluate the two variables (gingival display and Black triangle), a photo album is created that consist of two sets of photos which included six different photographs in each set. The frontal view of young adult female smile was selected for evaluating the esthetic perception. The smile features in the photographs is digitally altered using Adobe Photoshop CS6. Black triangles images are created using 0.5-mm increments. The gingival display by decreasing (−) the distance (2.0 and 4.0 mm) and increasing (+) the distance (2.0, 4.0, and 6.0 mm). The photographs are printed on photographic paper to create a photo album and coded from 1 to 6 and the scoring was done using a 10 cm visual analog scale (VAS). The participants are asked to mark the VAS score according to the attractiveness of each smile image separately with individual ratings.The comparisonofsmile esthetic perception among age groups was done using the Mann-Whitney U test. On comparing, the results revealed that laypeople with 18-35 yrs have given more scores for 0 mm Black triangle and for 2 mm gingival display which showed statistically significant results. Comparison of images among different age groups does not show significant results. The impact on the perception of smile esthetics vary among different age groups in terms of gingival display and black triangle.

Orthodontic tooth movement following application of force features bone remodelling changes in periodontal and dental tissues. These necessary orthodontic tooth movement achieved by numerous orthodontic procedures that evokes pain sensations in patients, such as separator placement, archwire placement and activations. The aim of the study is to compare the levels of interleukin 1-beta and prostaglandin E2 in GCF with pain perception after placement of elastomeric separators with and without low level laser therapy. 12 patients scheduled for orthodontic treatment, were screened test and control. Mesial and distal elastomeric separators flanked the maxillary first molar arch. The experimental side received 20s of Ga Al As, diode laser irradiation at 810 nm, 2 J/cm2, 200 mW power output, while the control tooth did not. GCF was collected from the mesiobuccal and mesiopalatal sides of first molars in the maxillary quadrant before, 1hr, 24 hours, and 48 hours after separator installation from both groups to quantify IL1-b and PGE2. The control and experimental group had IL-1β levels of 18.609 ng/ml (SD = 3.833) and 17.582 ng/ml (SD = 2.425) at the 'Before' time point, with p&#60; 0.001. Significant variations in IL-1β and PGE2 were observed from baseline, with p &#60; 0.001. After 1 hour, IL-1β levels significantly increased to 132.678 ng/ml (SD = 9.628)/ 83.848 ng/ml (SD = 8.833).In the 24-hour interval, IL-1β levels increased dramatically to 185.283 ng/ml (SD = 9.875) and 116.998 ng/ml (SD = 5.680). By 48 hours, IL-1β levels remained high at 157.459 ng/ml (SD = 10.141) and 103.664 ng/ml (SD = 9.662). Low-level laser therapy has been shown to reduce pain perception and decrease inflammatory mediators IL-1β and PGE2 in GCF patients with elastomeric separators. A positive correlation exists between these biomarkers, pain perception, and laser irradiation across all time intervals.
