Хураангуй: Энэ судалгааны зорилго нь өгөгдөл олборлолтын холболтын дүрэм (association rule) ашиглан оюутнуудын хичээлийн сурлагын хамаарлыг тодорхойлох явдал юм. Оюутнуудын хичээлийн үнэлгээ хоорондын хамаарлыг илрүүлснээр оюутны гүйцэтгэлийг урьдчилан таамаглах, хичээлийн ачааллыг зохицуулах, сургалтын хөтөлбөрийг үр дүнтэй болгох зэрэг боловсролын чанарыг сайжруулахад бодитой хувь нэмэр оруулах боломжтой. Судалгаанд Монгол улсын их сургуулийн Мэдээллийн технологи бакалаврын хөтөлбөрийн 5 жилийн туршид хуримтлагдсан оюутнуудын хичээл ба үнэлгээний өгөгдлийг ашиглав. Apriori алгоритмын тусламжтайгаар хичээлүүдийн A үнэлгээний давтамж болон хоорондын давхцал дээр үндэслэн хамаарлын дүрмүүдийг гаргасан. Түүнчлэн дээрх аргаар F үнэлгээний давтамж болон хоорондын давхцал дээр үндэслэн амжилтгүй суралцах хамаарлын дүрмүүдийг гаргасан. Судалгааны үр дүнд, жишээлбэл, “XXX хичээлд A үнэлгээ авсан оюутнуудын XXX% нь XXX хичээлд мөн A авсан" гэх мэт өндөр итгэлцүүр бүхий дүрмүүд илэрсэн. Энэ нь хичээлүүдийн агуулгын уялдаа, оюутны чадварын чиг хандлага, болон сургалтын төлөвлөгөөг оновчтой болгоход үнэтэй мэдээлэл өгч байгааг харуулж байна.
SISi information system is a web-based, centralized storage of information and web-based service providers based on linked databases developed for business requirements. Due to the growth of this user demand and the continuous improvement of connection speed and availability of users and devices accessing web systems, the need for additional solutions has arisen. In particular, the distribution of limited resources in the web environment has led to a tendency for clients to access resources first, creating a very competitive demand situation in the system. In that situation, this phenomenon was observed in the course selection process of the School Information Management System of NUM and the reliability of the service continued to decrease in each term, which became the reason for conducting this research
In this article, we discuss web-based system development, including its trends, stages of software architecture development, comparison of service-oriented, microservices, and serverless architectures, and research on scalability. We also delve into software re-engineering techniques, methods for migrating old web system architectures to new ones, and the new architecture's structure and components. Our research and methodology aimed to improve the architecture of a web access system in need of change, and we implemented a test using a case study on the SiSi system of the National University of Mongolia.
Managing high-demand concurrent requests in web-based systems such as a university management system's course selection module is crucial to database management, especially in centralized databases where multiple users(students) may select and modify data concurrently. In a centralized database system, concurrency control mechanisms are implemented to ensure that transactions are executed orderly and controlled, preventing issues such as lost updates, uncommitted data, and inconsistent reads. Concurrency control systems in centralized databases play a crucial role in managing data consistency and ensuring that transactions are executed correctly in a multi-user environment. In this paper, we will introduce the course reservation module of the university management system and solutions for managing high concurrent access to the centralized web-based database system. Course reservations is an end-to-end booking, distribution, and fulfillment solution for managing students’ personalized curriculum plans, including course selection, classroom seat reservations, pricing, and payment services. Pricing allows us to build and deliver the total tuition fee for various course rates based on local university rules and government taxes.
Сургалт удирдлагын систем үйл ажиллагаа, системийн архитектурын тухай. Өндөр хандалтын үед систем ачаалал даах чадварыг нэмэгдүүлэхийн тулд авч хэрэгжүүлж байгаа архитектурын өөрчлөлт, шийдлүүдийн талаарх илтгэл.
As virtual tour and virtual reality technology advances, resolution with gigapixel panoramic images become available. Visualization technique for gigapixel panoramic image needs to perform fast without any delay to access gigapixel ultra high resolution image data through wired or wireless internet by a Mobile, Tablet or a standard PC. Also, several popular visualization formats like equirectangular projection were developed to map a real scene to a panoramic image. However, Equirectangular projection may not the best choice when considering an image quality because of the distortion on both poles of the sphere. In this paper, we show the result of the evaluation for the projection formats using various comparison method to find which projection format (Equirectangular Projection, Cubemap Projection and Octahedron projection) and visualization technologies provides better image quality and speed of loading over internet. We exclude other format that has lower quality than the equirectangular projection format used in this experiment.
The most important problems (facing higher education institutions) are enhancing quality assurance. Quality assurance is at the heart of academic activities in higher education institutions (HEI) in today’s world. One of the methods to determine the quality of HEI is analyzing and summarize the satisfaction of stakeholders. The most important problems (facing higher education institutions) are enhancing quality assurance. One of the best ways to overcome this problem is by using a decision support framework for quality assurance. That framework is analyzing HEI’s historical data and supporting decision-making activities.
Equirectangular panoramas based virtual tours are popular tool for achieving 360-degree immersed viewing experiences. Nowadays, virtual tours are very popular and many people would like to see a virtual house before the acquisition of the real one. A virtual tour captures a scene from one point and viewers software allows the user to control the viewing direction, but usually the viewer is not allowed to move around and interact the objects in the virtual tour. This study proposes a strategy for transforming virtual tour with the effect of moving and interacting in three dimensions using full body motion sensor - Shadow. Preliminary proof of concept test shows that the strategy allows free translation within 360 virtual tours.
