Authors: Aksoy Yunus , Sehitogulları Abidin
Published: May 2024

Giriş: Sternum fraktürleri, şiddetli toraks travmasının bir göstergesi olarak kabul edilir. Bu çalışmanın amacı, izole ve komplike sternum fraktürlerinin klinik prognoz üzerindeki etkilerini karşılaştırmaktır.
Gereç ve Yöntemler: Ocak 2018- Ocak 2023 tarihleri arasında künt travmaya bağlı sternum fraktürü tespit edilen 139 hastanın verileri retrospektif olarak değerlendirildi. Olgular izole sternum fraktürü (İSF) (n=57, %41) ve komplike sternum fraktürü (KSF) (n=82, %59) olarak iki gruba ayrıldı.
Bulgular: Olguların yaş ortalaması 52,9±12 (minimum=20 yıl, maksimum=80 yıl) idi ve olguların çoğunluğu erkekti (n=99, %71,2). KSF olgularında en sık görülen ek patoloji, %47,5 (n=66) ile kemik fraktürüydü. En sık eşlik eden kemik dışı patoloji, poststernal hematom (n=26, %18,7) idi. Bir olguda mortalite gözlendi (%0,7). Yedi olguda (%5,0) cerrahi sternal fiksasyon uygulandı. İSF grubunda istatistiksel olarak daha fazla nondeplase sternum fraktürü gözlendi (%87,7'ye karşılık %61,0, p=0.001). İSF grubunda yoğun bakım ünitesinde kalış süresi (medyan 1 gün karşılık medyan 3 gün, p=0.04) ve hastanede kalış süresi (medyan 2 gün karşılık medyan 3 gün, p=0.001) daha kısaydı. Deplase sternum fraktürü saptanan hastalarda, hastanede kalış süresi daha uzundu (medyan 4 gün karşılık 2 gün, p=0.001).
Sonuç: Sternum fraktürlerinde prognoz, fraktüre eşlik eden patolojilerle ilişkilidir. Sternum fraktürünün komplike olması veya deplase olması hastanede kalış süresini uzatmaktadır. İSF olan olguların hastanede kalış süresi kısadır ve prognozları iyidir.

Published: May 2024

La creatividad ha tenido una notable trayectoria a lo largo de la historia, ya que su conceptualización se remonta a Aristóteles, quien la abordó en su texto sobre la autopoiesis. Se destaca la transformación y el poder de crear inherentes al ser humano. Posteriormente, Foucault (1994) profundizó el tema en su obra Hermenéutica del sujeto, donde se expone la creatividad como el acto de transformación e interpretación de la realidad. Por consiguiente, este capítulo se enfoca en la reconceptualización de la creatividad en la educación, aplicada tanto por maestros como por estudiantes.

HOTS is one of the reforms and priorities for implementing learning in Indonesia. The results of interviews with colleagues obtained information that students had difficulty understanding the material on Quadratic Equations and Functions. This difficulty occurs because students often memorize formulas in finding roots or solving quadratic equations. LKPD is currently used on average contains material, sample questions, and exercises, and rarely invites students to find concepts. Researchers consider it necessary to develop LKPD characterized by the online guided discovery of Quadratic Equations and Functions that meet the valid, practical, and effective criteria. Guided by the Plomp development model, by testing the validity, practicality, and effectiveness of LKPD in learning. The results showed that the average practicality of the observers was 3.0, meaning that the worksheets used were practical with a high level of practicality. The average student response through a questionnaire of 3.67 shows a positive attitude, and the average mastery of teaching materials is 79.56 with a completeness level of 78% indicating that the HOTS-based LKPD Guide Discovery is effective.

HISTORICAL BACKGROUND OF THE CONSTRUCTION OF MOSQUES IN IRAN
Authors: Krupa Michał , Shevchenko Lidiia
Published: May 2024

The article examines the historical prerequisites for the development of the Iranian Islamic school of architecture. Islam was transferred to the territory of the developed Persian kingdom, with thousands of years of cultural and architectural traditions, with the powerful religion of Zoroastrianism. These traditions turned out to be so resistant to changes that they did not disappear, but in a transformed form penetrated into Islamic architecture in the territory of Iran and influenced the creation of a peculiar type of "aywan type" mosque with a modified dome "chartac" in the planning structure.
The non-coincidence of historical and architectural periods is argued, three periods of mosque construction are highlighted: early, middle and high.
Historical periodization of mosques in Iran does not correspond to architectural periodization, which is based on changes in the image of mosques.
In particular, in the early period of the establishment of Islam in Iran in the 7th - 8th centuries. not. the influence of pre-Islamic traditions of construction and decoration is felt. There are quite a few mosques, they are dominated by constructions over decoration, interiors are monochrome.
In the middle period of the 9th - 15th centuries. not. the restriction of the construction of new mosques is caused by the rule of foreigners. During this period, new structural schemes are introduced and the decor becomes more complicated.
Period XVI - beginning XVIII century marked by the flourishing of the religion of Islam, which is expressed in the activation of the construction of new mosques with a more complex and developed layout and a formed hierarchy of mosques (cathedral mosques "jame", city mosques, village mosques, etc.).
In all three periods, the main centers of mosque construction were Isfagan and Shiraz, through which the Great Silk Road passed.
