APPLICATION OF BUILDING INFORMATION MODELLING (BIM) FOR SAFETY MANAGEMENT (SM) DURING THE OPERATION AND MAINTENANCE (O&M) PHASE IN BUILDINGS IN KAZAKHSTAN
(Nazarbayev University School of Engineering and Digital Sciences, 2022) Kopeyev, Dastan
Safety management is one of the key concerns of the construction objects industry.
Building information modeling enables the creation of a digital built environment of the
building. It could also be applied for early safety issues identification and safety management
throughout the construction project lifecycle. Currently, BIM usage for building O&M phase
safety still has little attention. There are different studies evaluating its general efficiency in early
safety risks identification and usage of the BIM model for safety management during building
operation and maintenance. Kazakhstan is currently in the important stage of BIM adoption, but
no studies observe BIM application for Kazakhstani building O&M safety.

ENGINEERING PROPERTIES OF CEMENT-TREATED SILTY SAND SUBJECTED TO FREEZE THAW CYCLES
(Nazarbayev University School of Engineering and Digital Sciences, 2022) Sagidullina, Nazerke
The problem of soft ground is currently of great interest, as with the rapid development of
infrastructure, researchers are trying to cope with the improvement of properties of problematic
soil to build structures on it since any structures built on weak soils can be easily damaged. In cold
regions, the problem of weak soils is further exacerbated by freeze-thaw cycling, resulting in
reduced soil strength. For the improvement of soil properties, the soil stabilization method can be
used. For such purposes, ordinary Portland Cement (OPC) is commonly used. However, despite
the effectiveness of OPC cement as a binding material, it produces a significant amount of carbon
dioxide emission. As an alternative to OPC, calcium sulfoaluminate (CSA) cement can be used.
Therefore, the purpose of this research study is to present the results from laboratory experiments
to evaluate the effectiveness of the soil treatment method using CSA cement for the improvement
of the properties of silty sand. The unconfined compressive strength (UCS) and ultrasonic pulse
velocity (UPV) testing conducted on the soil samples that were cured for 3, 7, and 14 days and
subjected to 0, 1, 3, 5, 7, 10, and 15 freeze-thaw cycles. The water content is defined from the
optimum moisture content and three different cement content were used, 3%, 5%, and 7%.
Applying the results from the unconfined compressive strength (UCS) test, the strength loss/gain
and resilient modulus parameters were obtained. The findings of the study show that the strength
and pulse velocity values decreased with the exposure of soil specimens to cyclic freezing and
thawing. However, improvement in soil performance can be observed with the use of CSA cement.
Overall, the application of CSA cement for treatment purposes could be an effective method to
enhance soil performance and meet the subgrade design requirements.
УСТОЙЧИВОСТЬ УНИВЕРСИТЕТОВ В ОТНОШЕНИИ МОДЕЛИ ФИНАНСИРОВАНИЯ СИСТЕМЫ ВЫСШЕГО ОБРАЗОВАНИЯ В РЕСПУБЛИКЕ КАЗАХСТАН В УСЛОВИЯХ ПЕРЕХОДНОГО ПЕРИОДА.
(Nazarbayev University Graduate School of Education, 2019) Айт Си Мхамед, Али; Каса, Рита; Сагинтаева, Аида; Воссенштейн, Ганс
В течение последних четырех лет международная команда, состоящая из научных сотрудников и преподавателей Высшей школы образования Назарбаев Университета, а также казахстанских политических деятелей, практиков и представителей заинтересованных сторон, работала над диагностическим анализом приоритетных направлений текущих образовательных реформ в Республике Казахстан. Цель исследования заключается в оказании аналитической поддержки при разработке и осуществлении национальной политики в различных секторах образования.
В 2016 году, исходя из обсуждений с представителями государственных органов, лидерами в области образования, практиками и другими заинтересованными сторонами, команда проекта сосредоточилась на изучении вопросов устойчивости университетов к действующей модели финансирования системы высшего образования как на одном
из основных приоритетных направлений развития страны. Руководствуясь такими стратегическими программными документами, как «План нации «100 конкретных шагов», «Государственная программа развития образования на 2011-2020 годы», «Государственная программа развития образования и науки на 2016-2019 годы», команда проекта
осуществляла сбор и анализ данных посредством организации встреч с практиками, посещала общеобразовательные средние школы, колледжи и университеты по всей стране. Все это позволило получить информацию о состоянии образовательных реформ, а также выявить их сильные и слабые стороны с целью дальнейшей модернизации системы образования в стране. Команда проекта также встретилась с ведущими международными экспертами, которые поделились своим опытом работы над приоритетными темами
проекта. В ходе исследования был проведен всесторонний обзор и анализ предыдущих и действующих политик и практик РК. Эти данные легли в основу диагностического отчета ВШО НУ “Разработка стратегических направлений реформирования образования Республики Казахстан на 2015 - 2020 гг.” (2014).
The Effects of Perturbation-Based Training (PBT) on Functional Balance in Children with Cerebral Palsy: Pre-Post Clinical Trial
(Nazarbayev University School of Medicine, 2024-04-03) Karibzhanova, Dilnoza
This study investigates the efficacy of a combined perturbation therapy, delivered simultaneously from the ground and in the transverse plane, to enhance gait stability and functional balance in children diagnosed with cerebral palsy at Gross Motor Function Classification System (GMFCS) levels I–II. With a minimum expectation of three participants aged between 14 to 18 years old, our research hypothesizes that combining perturbations will lead to greater improvements in functional balance, endurance, power and Muscle Activation Index. We anticipate that participants receiving combined perturbations will exhibit superior functional balance outcomes. The study employs standard equipment alongside an indigenous autonomous system developed to administer random perturbations to participants. Through this investigation, we aim to determine the effects of perturbations given from the ground and in the transverse plane on postural and functional balance of children with CP to enhance their overall quality of life.
