대부분의 디자이너는 3DS MAX와 같은 전문 3D 애니메이션 저작도구를 사용하여 수작업으로 애니메이션을 제작한다. 이 방법은 많은 시간과 노력을 필요로 하며, 애니메이션 캐릭터들이 서로 상호작용 할 수 없다. 이를 개선하기 위해, 본 논문에서는 3DS MAX플러그인 형태의 인공지능 미들웨어를 설계하고 미들웨어에 필요한 인공지능 표현 구조와 내부 처리 방안을 제안한다. 제안 방법은 캐릭터가 보유할 인공지능 요소를 도형과 선분으로 그려 표현하는 방법으로 캐릭터의 인공지능 구조를 제작한다. 실험을 위해 기존 방법과, 제안하는 방법을 사용하여 동일한 애니메이션을 제작하고 작업량을 측정하였다. 실험 결과 소규모 작업에서는 기존의 방법과 비슷하거나 작업량이 많으나, 대규모의 작업에서는 기존 방법에 비해 최대 43%의 작업량 감소를 확인하였다. 본 논문에서 제안하는 방법을 사용하면, 애니메이션에서 캐릭터간의 상호작용이 가능하며 작업량 감소 효과를 얻을 수 있다.

Today, further education of adults in the UK is one of the developing areas of continuing education. The Open University with distance learning, in the process of which innovative forms and methods based on computer and telecommunication technologies are used, is particularly successful in the organization of additional education of the adult population. The advantages of distance learning, multimedia - the latest information technologies, which provide the combination of graphic images, video, sound with the help of modern computer tools, are noted. The basic principles and forms underlying the technologies and forms of work with the elderly are defined. The international experience of implementing "Universities of the Third Age" is summarized. The most widespread approach in adult education in Great Britain is informational. The use of computer technologies motivates a new paradigm in educational methods and strategies, which requires new approaches, forms of learning, and innovative ways of delivering educational materials to adult learners. Information technologies have gained great popularity in such activities as distance learning, online learning, assistance in the education management system, development of programs and virtual textbooks in various subjects, online search for information for the educational process, computer testing of students' knowledge, creation of electronic libraries, formation of a single scientific electronic environment, publication of virtual magazines and newspapers on pedagogical topics, teleconferences, expansion of international cooperation in the field of Internet education. The information technology of synchronous distance learning "online" has gained considerable popularity in the educational process today. A promising direction is the use of multimedia technologies in educational activities to create a design of a virtual computer environment by decoding audiovisual information.

It is not practically feasible to apply hardware-based fault-tolerant schemes, such as hardware replication, in mobile devices. Therefore, software-based fault-tolerance techniques, such as checkpoint and rollback schemes, are required. In checkpoint and rollback schemes, the optimal checkpoint interval should be applied to obtain the best performance. Most previous studies focused on minimizing the expected execution time or response time for completing a given task. Currently, most mobile applications run in real-time environments. Therefore, it is extremely essential for mobile devices to employ optimal checkpoint intervals as determined by the real-time constraints of tasks. In this study, we tackle the problem of determining the optimal inter-checkpoint interval of checkpoint and rollback schemes to maximize the deadline meet ratio in real-time systems and to build a probabilistic cost model. From this cost model, we can numerically find the optimal checkpoint interval using mathematical tools. The performance of the proposed solution is evaluated using analytical estimates.

Use of a hypertext is growing as multimedia and hypermedia systems become popular. The major difference between hypertext-based and ordinary user interfaces is navigation. Typically, there are two major navigation problems in a hypertext compared to the ordinary user interface: "Disorientation" and "Cognitive Overload". To reduce or eliminate these problems of the hypertext system, a variety of aiding tools have been proposed. Among them, a local map is a good tool for helping users navigate through screens, especially for a large and complex system. This study examined three major design variables of a local map in a hypertext: breadth, depth, and functionality of a map. A human factors experiment was conducted to investigate the effects of these variables. Based upon the results of the experiment, design guidelines are suggested.
