The purpose of this paper was to analyze the kinds and roles of multimedia materials in E-works that are distributed with elementary textbooks (3~6 grade) of the 2009 revised science curriculum. Five criteria (forms, goals, key competencies, inquiry process, running time) were set for this. The sample of the paper was the 784 multimedia materials in E-works of elementary science textbooks (3~6 grade) of the 2009 revised science curriculum. The results of the multimedia materials analysis are as follows: The result of the material forms of multimedia is that the form of highest ratio is text type. But all forms were used evenly in E-work. 56.2% of the multimedia materials are for "inquiry" in the goal criteria, and 65.0% of the multimedia materials are related to "science inquiry" in the key competencies criteria. Two facts indicate many multimedia is used to develop students' inquiry ability. However the ratio of multimedia materials in motivation step is higher than that in inquiry activity step. In analysis of running time, the ratio of "under 5 min" multimedia materials is the highest. But, the ratio of 5~10 min multimedia materials in inquiry part is higher than that in motivation part in The Chi-square test between "running time" and "parts" that consist of motivation part and inquiry part. Through the analysis of module and the categorizing the multimedia materials, we found that the multimedia materials play eleven roles in E-works that are distributed with elementary textbooks.

The zombies in AVG games are not divided into different game occupations. To address this issue, this paper starts by selecting those popular zombie games as the research object. Then, a number of samples will be collected from the roles of zombie and these different roles of zombie will be classified by profession depending on the characteristics of these roles. On this basis, the roles will be given a new title to describe their profession. Then, semantic analysis will be conducted to search for the words that can be used to describe the roles of zombie. Besides, there will be 10 experts in design and 10 professional zombie game players invited to choose from the collected adjectives. The most selected words will be used in this study to conduct cognition assessment, before the making of questionnaire. Then, the questionnaire data will be collected and converted into a statistical model form for indicating the value of ability by group and profession.

Recent advances in Internet-of-Things and wearable computing have established computationally sufficient infrastructure to remove the barriers of physical locations. The recent COVID-19 pandemic has accelerated the use of remote collaboration, work-from-home, teleconferencing, online education, digital twin, and metaverse enriched with various configurations of augmented reality, virtual reality, mixed reality, and extended reality. Beyond specialized niche wearable applications in the medical and entertainment domains, we aim to identify the underlying characteristics of smartglass-enabled killer applications for everyday use. In this paper, we analyze intermediary roles in remote collaboration consisting of authoritative supervisors, synergetic collaborators, and speculative explorers. We also propose technical components for smartglass-assisted interactive remote collaboration composed of personal tracking, teleconference, and interaction components. More specifically, the application tasks of each intermediary role and objectives of three functional components are defined and elaborated.

In 2013, Academy Award for Best Animated Short Film was granted to Walt Disney's short animation, (2012). With various aspects of its excellence, I focus on the very effective use of digital lightings and underscores for storytelling as its success factors. In this respect, this paper aims at analyzing the roles of the visual factors, especially tone, contrast, etc. created by lightings, and audio factors, especially underscores, in the film's story development. I find that can be characterized by the well-built story structure with distinct three acts. The main stream of the story is expressed with the overall mood that is created by the fine adjustments of brightness of the main light, and contrast. And the direction and the intensity of the lighting successfully describe the emotions of the characters in each scene. In addition, I find that properly chosen and positioned underscores make the development of the story more dynamic and more harmonized.

멀티미디어 교육의 중요한 목표 중 하나는 멀티미디어 컨텐츠를 직접 저작하는 능력을 함양하는 데 있다. 이를 위한 방법으로 프로젝트기반의 멀티미디어 컨텐츠 저작 교육을 실시하고 그 효과를 검정해 봄으로써 더 나은 교수전략의 개발에 기여할 수 있다. 본 연구에서는 멀티미디어 교육의 목표에 충실하기 위하여 멀티미디어 컨텐츠 저작을 위한 프로젝트 진행방식으로 대학에서 한학기 동안 멀티미디어 교육을 수행하고 그 효과를 학습자의 특성에 따라 분석하였다. 그 결과 학습자 개인의 특성 중 '나이', '편입학석부' 등에 따른 학습효과의 차이가 통계적으로 유의한 것으로 드러났으며 '프로젝트에 대한 관심도'와 '프로젝트에서의 역할' 등에 의한 성취도 차이도 뚜렷하게 나타났다.

이론적으로 U-Learning 환경 하에서는 학습자가 학습하고 있다는 느낌이 들지 않을 정도로 실시간으로 또한 상황대응적으로 학습이 이루어진다. 그러나 본 연구에서는 u-Learning 도입의 초기단계를 가정하고 PMP(Personal Multimedia Player)를 이용한 학습 환경을 주로 살펴보았다. 또한 본 논문에서는 PMP를 활용한 학습 환경 하에서 사용자들이 인지하는 학습활동의 장애요인을 도출하는데 주요 목적이 있다. 이를 위해 64명의 사용자와 비사용자를 중심으로 요구분석을 실시했으며, 그 결과 PMP사용동기, 비용, 사용콘텐츠, 불만족 사항 등을 분석 보고하고 이를 토대로 6가지 확산의 장애요인인 인식의 부족, 자신감의 상실, 부작용, 교육 및 지원의 부족, 비용, 콘텐츠 부족 등을 제시하였다. 더불어 이러한 PMP 활용 u-Learning 확산의 장애요인을 최소화하기 위한 가이드라인도 제언하였다.

This paper examine the changing ecosystems in Malaysia, starting with the government policy driven greenfield cluster of Cyberjaya, which is part of the Multimedia Super Corridor (MSC) mega project. In this context of an emerging economy, predominantly production oriented, the role of the government was crucial with respect to implementing policies and building infrastructure for the ecosystems. First, the roles played by the cluster development agency, universities, and industry are explained. As the cluster developed, this paper, taking an entrepreneurial ecosystem approach, explores how some actors evolved and changed their roles to become catalyst organisations established for the cluster now serving nationwide. This was followed by the emergence of new actors in the ecosystems, for example, knowledge intermediaries, and new roles for universities. In addition to actors such as universities and industry, this paper recognizes the emergence of media organisations as new actors in the entrepreneurial ecosystems in Malaysia.

In this study, Monte Carlo (MC) simulation is conducted with recurrence relation to study the effect of SiO₂ with different particle size and their roles in enhancing the ionic conductivity and lithium transference number of PMMA composite polymer electrolytes (CPEs). The MC simulated ionic conductivity is verified with the measurements from Electrochemical Impedance Spectroscopy (EIS). Then, the lithium transference number of CPEs is calculated using recurrence relation with the MC simulated current density and the reference transference number obtained. Incorporation of micron-size SiO₂ (≤10 ㎛) fillers into the mixture improves the ionic conductivity from 8.60×10^-5 S/cm to 2.35×10^-4 S/cm. The improvement is also observed on the lithium transference number, where it increases from 0.088 to 0.3757. Furthermore, the addition of nano-sized SiO₂ (≤12 nm) fillers further increases the ionic conductivity up towards 3.79×10^-4 S/cm and lithium transference number of 0.4105. The large effective surface area of SiO₂ fillers is responsible for the improvement in ionic conductivity and the transference number in PMMA composite polymer electrolytes.
