Cilj: Ovim radom nastoji se ukazati na važnost uspostave sustava za ocjenu kvalitete radiološke slike u konvencionalnoj radiografiji. Metode: Studija je provedena retrospektivno, usporedbom kvalitete radiološke slike i načina dobivanja radiološke slike. Ocijenjeno je 20 radioloških slika zdjelice, a ocjena je provedena prema europskim kriterijima za kvalitetu radiološke slike zdjelice. Kvalitetu slike su ocjenjivali radiolog, radiološki tehnolog i student radiološke tehnologije. Usporedbom s istim kriterijem analiziran je i način rada pri oslikavanju zdjelice u 3654 pacijenta te srca i pluća u 57758 pacijenata. Analizirana je i praksa sužavanja rendgenskog snopa na područje od interesa za 50 radioloških slika srca i pluća. Rezultati: Samo jedna slika zdjelice ocijenjena je najvećom mogućom ocjenom od strane sva tri ocjenitelja. Subjektivne procjene ocjenitelja vezano uz odabir parametara ekspozicije razlikovale su se u većini ocjenjivanih slika zdjelice. Naponi na rendgenskoj cijevi korišteni pri oslikavanju zdjelice većinom su bili u preporučenom rasponu, dok su za srce i pluća u većini slučajeva bili manji od preporučene vrijednosti. Zdjelice su većinom oslikavane korištenjem udaljenosti žarišta rendgenske cijevi od prijemnika slike koje su bile u prihvatljivom rasponu osim u slučaju onih pacijenata koji su za vrijeme oslikavanja stajali. U slučaju oslikavanja srca i pluća ove su udaljenosti uglavnom bile u prihvatljivom rasponu osim u slučaju ležećih pacijenata kada je veći broj pacijenata oslikan korištenjem manjih udaljenosti. Svih 50 analiziranih radioloških slika srca i pluća bilo je uređeno na način da su po provedenom oslikavanju uklonjeni rubni dijelovi slike. Zaključci: Rezultati provedene analize ukazuju na potrebu uspostave i provedbe sustava za ocjenu kvalitete radiološke slike koji bi uključivao i analizu načina rada.
Dialogue of ideas in the baroque opera: socio-cultural and philosophical reflections
Authors: Ciobanu Liliana
Published: October 2024

The Baroque era represented a defining moment in the evolution and development of European culture, marking a period of transformations and innovations in all the artistic domains. Characterized by expressiveness, drama, and opulence, the Baroque was profoundly influenced by the socio-cultural and ideological context that shaped the thought and society of the 17th and 18th centuries. Within the cultural landscape of the period, opera played a central role, subtly illustrating the dialogue between the philosophical thought and opera creation. The Lyric Theater became a relevant medium for reflecting and reinterpreting the ideological principles, contributing to shaping the cultural consciousness of the time. The study analyzes the relationship between the philosophical ideas and the lyrical creation during the Baroque period, investigating the mode in which the social-cultural context and the ideology of the era influenced the opera art and the ways of expressing the philosophical ideas in this artistic form.

Indonesia is a country with diverse cultures, and these cultures need to be preserved, one way being through Law No. 11 of 2010 on Cultural Heritage. The traditional village of Cikondang in West Java has been designated as cultural heritage, which has a significant impact on the preservation of its customary forest. This study aims to analyze the impact of this designation on the conservation of the Customary Forest. Using a qualitative method, the research was conducted through interviews, observations, and literature studies. The results show that the designation as cultural heritage strengthens the protection, management, and preservation of the customary forest, which serves as a water reservoir, a habitat for flora and fauna, as well as a center for education and research. Strict customary regulations, such as restrictions on entering the forest on certain days and the use of resources only for customary purposes, help maintain the sustainability of the ecosystem. The designation as cultural heritage also boosts tourism and the economic well-being of the local community. Thus, the preservation of the customary forest in the traditional village of Cikondang is not only rooted in local wisdom but also reinforced by national legal policies, which overall support the sustainability of the ecosystem and the welfare of the local community.

This study aims to improve the learning of Catholic Religious Education in class X Tari at SMK Negeri 1 Kasihan, which was initially dominated by the less interactive lecture method, affecting the motivation and learning outcomes of students. To overcome this, the Problem Based Learning (PBL) method assisted by video media is applied, which involves active students in solving problems relevant to everyday life. The research was conducted in two cycles, with PBL steps such as problem orientation, individual and group investigation, and presentation and evaluation of results. The results showed significant improvements in the cognitive, skill and affective aspects of learners. The cognitive average score of the group task increased by 11.2%, from 79.7 in cycle I to 90.8 in cycle II, while the individual task increased by 12%, from 76.8 to 89. In terms of skills, the average score increased by 13%, from 76 to 88. The affective aspect also experienced a significant increase of 23.2%, from 63.4 to 88. The application of PBL assisted by video media proved effective in improving students' learning outcomes, both in terms of critical thinking, responsibility, and understanding and application of Catholic teachings. This study recommends the use of PBL method and video media as an effective learning strategy to improve the quality of learning Catholic Religious Education and Cultivation.

The basis of the poultry industry is the presence of parent flocks, and the lack of this causes the eggs to be transported for long periods and long distances, reducing the quality of hatching eggs and producing poor-quality, low-weight chicks. Therefore, the current study investigates the effect of different storage periods for different types of broiler chickens on the internal immunity of the egg and some qualitative characteristics of stored eggs. Three lines of broiler were used from three hatcheries (Ross 308-1: Ross 308-2: Cobb 508); these lines of eggs were imported from Türkiye and the Netherlands to Iraq, and all eggs were storage for four periods (15, 20, 25 and, 30 days) at seven c⸰. The results showed a significant (P≤0.05) increase for (line- 2) in total IgY at 25 days, and line three increased significantly (P≤0.05) in the HU unit at 25 days too. Meanwhile, there is no significant difference between periods in egg weight loss (Table 2), albumin pH, relative albumin weight, and yolk weight. It is concluded from the study's results that any storage duration may affect the egg's internal immunity and its qualitative characteristics. Thus, it may negatively affect the hatching rate and characteristics of the hatched chicks.

Pulmonary TB (PTB) may recur due to reinfection or relapse after initial successful treatment. Based on microbiologically documented cases, we searched Embase, PubMed, Web of Science, and Medline for PTB recurrence. The timeframe of overall recurrences, relapse, reinfection, and risk factors were assessed. We compared the time to recurrence, relapse, and reinfection from treatment completion and plotted this using Kaplan–Meier curves. This systematic review included 23 articles describing 2,153 PTB recurrences in 75,224 treated people across all continents. Genotyping data to distinguish relapse from reinfection was available for 402 recurrences. The cumulative recurrence percentage was 2.9% over 5 years, and the median time for recurrence was 18 months (95% CI 16.99–19.0). Most recurrences (93%) were in HIV-negative people. Relapse occurred earlier than reinfection at 12 months (95% CI 10.86–13.14) vs 24 months (95% CI 21.61–26.39) (P< 0.001, χ259.89). In low TB burden settings, recurrences were mainly caused by relapse (85%), whereas in high-burden settings, relapses comprised 56% of recurrences. Recurrences occurred slightly earlier in HIV-positive patients (P= 0.038, χ24.30). The emergence of resistance to one or more first-line anti-TB agents was documented in 40 of 421 cases (9.5%). Early recurrences are mainly relapses, while late recurrences are mainly reinfections.

A ceratoconjuntivite seca (CCS) ou olho seco é uma doença ocular frequentemente diagnosticada em cães. Objetivou-se com esse estudo retrospectivo caracterizar o perfil dos cães diagnosticados com CCS no Hospital Veterinário da Universidade Federal do Rio Grande do Sul no período entre Janeiro de 2007 e Agosto de 2024. Dados relativos à raça, ao gênero e à idade dos pacientes diagnosticados com CCS foram analisados. No período analisado foram diagnosticados 1127 cães com CCS. As raças mais acometidas foram a Shih Tzu (24,84%), Lhasa Apso (9,76%). Yorkshire Terrier (9,67%), Poodle (7,54%) e Cocker Spaniel (6,92%). Cães sem raça definida (SRD) também foram diagnosticados com CCS (14,55%). Em relação ao sexo dos animais, 52,44% dos pacientes eram fêmeas e 47,47% machos. Quanto a idade, 51,90% dos pacientes tinham mais do que sete anos de idade. Com base nos resultados apresentados foi possível concluir que a CCS acomete tanto cães de raças puras quanto cães SRD. Além disso, afeta principalmente fêmeas e cães com idade avançada.
