Ushbu maqolada ogʻir atletika sport turi doirasida dast koʻtarish mashqining texnik, tarixiy va fiziologik xususiyatlari ilmiy-nazariy asosda yoritilgan. Dast ko‘tarish harakati og‘ir atletikaning eng muhim va murakkab elementlaridan biri hisoblanadi. Maqolada ushbu harakatning bosqichlari, treningga tayyorgarlik jarayoni, mushaklar va asab tizimining ishtiroki, energiya almashinuvi jarayonlari, hamda sportchilarning texnikasi va natijalarini yaxshilash bo‘yicha takliflar berilgan. Shuningdek, dast ko‘tarishdagi jarohat xavfi va uni kamaytirish yo‘llari ham tahlil qilingan. Maqola og‘ir atletika bilan shug‘ullanayotgan sportchilar va murabbiylar uchun foydali nazariy va amaliy tavsiyalarni o‘z ichiga oladi.

Pneumonia is a significant health concern in pediatric populations, and while its respiratory effects are well-studied, its systemic impacts, particularly on the gastrointestinal system, are less explored. This paper aims to investigate the morphofunctional changes in the large intestine of children diagnosed with pneumonia, focusing on alterations in intestinal structure and function that may arise as a consequence of the disease. Pneumonia, often accompanied by systemic inflammation and antibiotic treatment, can lead to disturbances in gut microbiota, altered intestinal motility, and changes in mucosal integrity. These factors are essential to understanding the broader effects of pneumonia beyond the lungs. Through reviewing recent studies and clinical observations, this paper discusses the possible mechanisms behind gastrointestinal symptoms, such as diarrhea, abdominal discomfort, and changes in the gut microbiome, commonly observed in children with pneumonia. Furthermore, it examines how systemic inflammation during infection could exacerbate intestinal disturbances and impact the overall health and recovery of pediatric patients.

Mazkur maqolada 15–17 yoshli sambochi qizlarda tezkor-kuch sifatlarini rivojlantirishda murabbiylarning metodik yondashuvlari va ularning amaliy ahamiyati tahlil qilingan. Tezkor-kuch sifatining mazmuni, uni rivojlantirishda qo‘llaniladigan samarali metodlar, kuzatuvlar asosidagi natijalar va amaliy tavsiyalar yoritilgan. Tadqiqotlar natijasi murabbiylik jarayonida individual yondashuvning yuqori samara berishini ko‘rsatdi.

Ushbu maqolada tarmoq administratorlari tomonidan amalga oshiriladigan harakatlarni aniq qayd etish, ularni kuzatish va tahlil qilish maqsadida TACACS+ (Terminal Access Controller Access-Control System Plus) protokoli asosida monitoring tizimini loyihalash va amaliyotga joriy etish tajribalari ko‘rib chiqiladi. TACACS+ orqali markazlashtirilgan autentifikatsiya, avtorizatsiya va hisobga olish (AAA) xizmatlari yordamida tarmoq xavfsizligini ta’minlashning texnik va tashkiliy jihatlari yoritiladi.

Ushbu maqolada zamonaviy telekommunikatsiya tarmoqlarida markazlashtirilgan kirishni boshqarish tizimlarida TACACS+ va RADIUS protokollarining autentifikatsiya, avtorizatsiya va hisobga olish (AAA – Authentication, Authorization, Accounting) jarayonlaridagi o‘rni yoritiladi. Protokollarning texnik xususiyatlari, ishlash prinsiplari, afzalliklari va kamchiliklari taqqoslanadi hamda ularning tarmoq xavfsizligini ta’minlashdagi salohiyati tahlil qilinadi.
