1. 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) Core Univ. Seminar : Distance learning sub-group of e-Learning team （ 2004.5.14)

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

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

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.

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 NUKSU : 29 Mbps (Full frame) ChNUKSU : 6 Mbps (7 fps) ChNUKSU : 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
