  1. Core Univ. Seminar : Distance learning sub-group of e-Learning team（2004.5.14) Practical study of Korean and Japan Distance Learning between three points with DVTS Takashi FUJIKI, Byungdug JUN, Yusuke Morita, Daisuke YAGYU, (Nagasaki University) Sangsoo Lee (Chonnam Nat’l University) Kenji WATANABE, Toshihiko SHIMOKAWA (Saga University) (Kyushusangyo University)

  2. We performed international distance exchange/learning Feb. 18(Exchange), 19(Learning), 2004

  3. Exchange flow 1)Greeting speech(Head master of ChNU's MS) 2)Introduction of each school Introduction of each city, school, school events etc. 4)Q & A Q & A by each group using translation chat. 5)Greeting speech(Head master of NU's MS)

  4. Class Work Content • Learning about Energy Problem (Theme: Lets think future of energy beyond the sea!) • Materials: Map and graph using Web-GIS (Comparing with quantity of electric power by power generation about Korea, Japan, and other country) • Explanation by expert (Kind of power generation and quantity, and new energy)

  5. Class Work Expansion • Showing Coals • Burning coal has many problems. (Done away with fossil fuel, Exhaust harmful gases, Air pollution, Rise in temperature, Acid rain) • Electric power is clean. • Electric power is generated with coals. • Our countries, Korea and Japan, 60% of electric power generation need coal etc.. • Thinking dream energy together.

  6. Concept • Learning of Earth Environment breaking through the wall of country “ Let’s think about future energy beyond the sea “ • Connecting between three points, Gwangju, Fukuoka and Nagasaki

  7. Purpose • Practical study on international distance learning between three points with DVTS and Web-GIS

  8. DVTS Factors on International Distance Exchange Environmental Education Content Environment • Language-- Human Translation, Trans. Chat • Content-- Environmental Education • Materials of Learning -- Coal, Energy Map with Web-GIS • Environment -- DVTS(Video/Audio quality) Materials Human Translation,Trans. Chat Korean Japanese Language

  9. 3 Points Venue by DVTS Main Teacher & Translator Sub Teacher & Students Sub Teacher & Students Fukuoka Gwangju Nagasaki

  10. Reason for 3 points venue • Necessity of main teacher • Necessity of equal footing for each students ・School teachers have to care their students ・Main teacher’s class will be a master class and not main teacher’s class will be a slave class.

  11. Network • Link of schools : 100Mbps DVTS KOREN Genkai QGPOP JGN 1Gbps 1Gbps Chonnam Univ. Nagasaki Univ. Middle School Middle School 100Mbps 100Mbps

  12. DVTS DVTS DVTS DVTS DVTS DVTS DVTS DVTS DVTS Construction for 3 DVTS venue Kyusyusangyo Univ. Chonnam Univ. Nagasaki Univ. Video Mixer

  13. Classroom Construction ChNU • 3 Screens 1)DVTS 2)Trans. Chat 3)Web-GIS • 2 Mics • 2 Video Cameras for DVTS NU

  14. Nagasaki/Gwangju System Video out DV cam Video Switcher Audio Mixer Echo Canceller Etc. Video out DV cam Video out Video Out Projector DV cam DV cam Audio Out Audio Out IEEE1394 IEEE1394 DVTS Receiver DVTS Sender 100Base-TX Campus LAN HUB Projector Translation Chat PC Projector Web GIS PC

  15. Snap shots (ChNU) • Exchange • Introduction and Q&A with Trans. Chat

  16. Construction of KSU • Monitors 1)2 schools 2)Sending picture 3)Trans. Chat 4)IRC • 2MICs • video camera

  17. KSU System DVTS Sender to ChNU DVTS Receiver from ChNU Media Converter 100Base-TX IEEE1394 HUB DVTS Sender to NU DVTS Receiver from NU Media Converter IEEE1394 DV Deck DV Deck DV Deck Video Mixer Audio, Video Output Audio, Video Out Audio Mixer Echo Canceller etc Projector or Monitor Projector or Monitor Translation Chat PC Video Out Video Camera Projector or Monitor Web GIS PC

  18. Translation Chat • Short sentence • Divide a sentence by block • Expression look like not conversation

  19. Web-GIS as Learning Material • Displaying ratio of electric power generation • Also using graph

  20. Behavior of Bit Rate in Learning NU-KSU ChNU-KSU • NU KSU : 29 Mbps (Full frame) • ChNU KSU : 6 Mbps (7 fps) ChNU KSU : 8 Mbps (7 fps)

  21. Example of DVTS Screen Image Nagasaki (Recording at KSU) Gwangju (Recording at NU)

  22. Results of Questionnaire • Learner’s evaluation : good • Teacher’s evaluation : not so good

  23. Conclusion • We practiced international distance learning about environment education using high quality movie through gigabit network, human and chatting translation system between Korea and Japan.

  24. Future Work • Distance Learning using HDTV

  25. Acknowledgement • Core Univ. project • QGPOP • TAO • KOREN • G/H • e! project • KEPCO(Kyushu Electric Power Company) • Middle School of Chonnam Nat’l Univ. • Middle School of Nagasaki Univ.
