We propose a multilingual lecture-on-demand system, which searches lecture videos for segments relevant to user information needs across languages. We utilize the benefits of textbooks and audio/video data corresponding to a single lecture. We extract the audio track from a target lecture video, generate a transcription by large vocabulary continuous speech recognition, and produce a textual in...

THEORY LECTURES are boring and sleep inducing for students, and it is difficult to get their full attention during 1 h of lecture (7). The ability of students to concentrate diminishes 20–25 min after the start of the lecture (5). There is also a lack of active participation of students during theory lectures (10). In an effort to break the monotony of the lecture, an online blood grouping game...

We show here that the refined theorems for both lecture hall partitions and anti-lecture hall compositions can be obtained as straightforward consequences of two q-Chu Vandermonde identities, once an appropriate recurrence is derived. We use this approach to get new lecture hall-type theorems for truncated objects. The truncated lecture hall partitions are sequences (λ1, . . . , λk) such that λ...

This paper discusses the speech recognition of Japanese classroom lecture speech. In particular, we mention the influences of microphone differences and the language model differences on the speech recognition performance of classroom lectures. First, we collected actual classroom lecture contents from several universities in Japan. In this paper, we recorded the lecture speech using lapel micr...

We propose a lecture-on-demand system, which searches lecture videos for segments relevant to user information needs. We utilize the benefits of textbooks and audio/video data corresponding to a single lecture. Our system extracts the audio track from a target lecture video, generates a transcription by large vocabulary continuous speech recognition, and produces a textual index. Users can sele...

BACKGROUND/OBJECTIVES This research was conducted to compare lecture-and experience-based methods of nutritional education as well as provide fundamental data for developing an effective nutritional education program in elementary schools. SUBJECTS/METHODS A total of 110 students in three elementary schools in Jeollanam-do were recruited and randomly distributed in lecture-and experience-base...

Recently, various kinds of high-quality media systems have been developed. It is expected that these systems can be used to remote lectures. We are adopting these systems including high-speed network to construct a remote lecture based on "Instruction with Blackboard", which provides old-fashioned but very common style of lecture. This instruction style has been often avoided in remote lecture ...

The storyline of operas, with historical or fictional characters, often include potions and poisons. This has prompted a study of the chemistry behind some operatic plots. The results were originally presented as a lecture given at the University of Minho in Portugal, within the context of the International Year of Chemistry. The same lecture was subsequently repeated at other Universities as a...

Overview These notes consists of ve lectures. Each lecture covers the material that I will present with fuller details and exercises. I have also included some material in appendices which the reader might nd interesting but which I will not have time to cover in my lectures. Lecture 1 introduces both linear Grr obner bases and Grr obner bases for algebras. Lecture 2 surveys some of the basis a...

Background Osteoporosis is the most common metabolic bone disease that decreases bone mass, causes destruction and eventually friability. This disease is preventable, and because adolescent females are the high-risk population, teaching this age group is of the utmost importance. The aim of this study was to compare the effects of the two educational methods (Lecture and Pamphlet) on osteoporos...
