During 2008, the IEICE Korea, communication section had organized special workshop given by three experts on green IT area from Japan and Korea. This Green IT workshop was held in conjunction with the 19th HSN (high speed network) workshop, which is renowned workshop in communication field in Korea. The workshop was related to an important and rapidly growing green IT research area: energy and environmental technologies, new renewable energy policy, solar energy, USN technologies for green IT, climate change and green IT, ubiquitous sensor network technology and green IT biz model. About 60 attendees have signed in, including around 20 students and 40 engineers from manufactures and R&D area. The invited speakers brought their valuable experience and newest development in the field to the attendees, in particular, many young researchers through their clear presentation.

[PROGRAM]
17:00-17:10	Opening Remarks, "Status report on IEICE communications society" Prof. Chul-Hee Kang / The representative of IEICE Korea section, communication
Prof. Kang introduced the current status on the IEICE communication society as well as the IEICE to attendees.

17:10-17:40	"Trend in Energy and Environmental Technologies in ICT" "Status report on IEICE communications society" Tohru Maruno (President) /Energy and Environment Systems Labs. NTT, Japan
As concern for global warming and other environment problems heightens, many ICT 1 researchers are doing much work in energy and environmental R&D to promote a safe, secure and sustainable society. To this end, an accurate understanding of the environment must first be obtained in the form of tangible information. Next, measures for achieving specific reductions of environmental load must be implemented based on that environmental information, and finally, the effect of those measures must be appropriately evaluated. This presentation outlines the work from the following four main perspectives to enable people to lead safe, secure and sustainable lives. (1) Construct an efficient energy infrastructure to support the ICT system (2) Develop clean-energy technologies for ICT system (3) Develop sensors and other environmental technologies to visualize and/or to reduce environmental loads (4) Develop environmental-impact assessment technology for ICT services

17:40-18:10	"Solar Energy and IT" Young-Sun Kim (Principal Member of Engineering Staff) / Advanced Solar Techs. ETRI, Korea
The facts about solar energy are very positive and as you know solar energy comes in many different forms. The majority of us are most familiar with solar cells, but how does solar energy work because there are many different ways to create and store solar energy. Here are a few of those ways to become familiar with how solar energy works: (1) Solar Cells Most of us have seen solar cells used on calculators with LCDs. But they have also been used in many other ways. Solar cells use semiconductors (oftentimes, silicon) to generate electricity, directly from the sunlight. (2) Solar Fibers This is also a photovoltaic device (like the solar cells), only it does not use silicon. Rather, it has a solar tape that is made with titanium dioxide. This tape could actually be combined with building materials or even clothing. (3) Solar Pond A solar pond is made of three layers: the top layer as low salt content. The middle layer is an insulating layer with salt, and it prevents natural convection in the water (which would normally cause heat exchange). The bottom layer as a very high salt content and this layer can approach high temperatures. Because of all the densities in salt of the different layers, there are no convection currents (which normally transfer heat to the surface and then the air). These are just a few ways in which solar energy has been and is being created. As we gather more facts about solar energy we are beginning to see notice that the most common household type of solar energy is that created by solar cells. Nonetheless, these other types are very promising and certainly have their place and show the many opportunities we have to improve how solar energy works.
18:10-18:40	"�gKT Mobile USN Technologies for Green IT�h Yoon-Kee Kim (Director) / Future Techs. Lab. KT, Korea
Energy saving and the protection of environment for sustainable society is now global agenda, that we must achieve for the next generation and for our Earth. This activity around IT and ICT industry is called as Green IT/ICT. Though the most of the green IT/ICT would focus on the energy saving of IT/ICT equipments, we are focusing on the energy saving by IT/ICT technologies. The real target is not the energy saving, but is to establish ubiquitous digital sensor and actuator network environment and to encourage the technical innovation/revolution or new applications using this network platform. This is the end-to-end model that the Internet has achieved. In this presentation, he showed mobile USN technologies for green IT and computer monitoring of environment by KT project. The real goal of this project is sharing any digital information over the globe to achieve higher efficiency on human and social activities and to establish the digital network infrastructure to achieve sustainable innovations.
