Matt Flanigan, President, TIA: Well, today I would say speed and bandwidth. Especially, a little smile up to the consumer' is probably a big issue holding back the Internet. But security is also important with electronic commerce. And until they really solve that, people are not gonna feel secure.
Host: All right. Well, Let's introduce our guest.
We're joined by an executive from Effnet: Tomas Althen. Welcome to the program. We're delighted to have you. Tomas, let's start with this. What sort of Internet issue is Effnet dealing with? What kind of solutions do you bring to the table?
Tomas Althen, CEO, Effnet Group: The Internet is growing at a very rapid speed at the moment. As you must know, the number of users doubles every year. However, also the information on the net doubles every month. And this calls up the two issues we have been hearing about here, speed and security.
Host: Well, let's look at more details. Look at this video about the city council of Stockholm, Sweden.
Narrator on the video: Here is the power. The politicians and high civil servants at Stockholm County Council are used to having access to qualified information. Now with everyone using Internet and Intranet, some information has to remain secret. The decision on how to do this are mad here at IT Control. They have found the way to let 10, 000 employees use the Internet but some information can still be accessed only by qualified people.
This is the firewall keeping the information system secure. A box in the basement with software from Effnet. Scandinavia is known for its technology. Cellular phones and Internet are part of daily life. And here in Sweden there are some young, very innovative up-starting companies. One is Effnet, founded in 1997 and already on the world market.
As the world demands speed and security and reliability, Effnet's gigabit router on a card makes security easier. The generic plug-in card, firewaller and router in one, proves that they are ready to meet the world demand.
Host: Well, how does the firewall work? We were told a few days ago that one of the new methods of transmission was to break everything up into little packets, send them all into the Internet and hope they arrive in the same order, and so on. Is the protection of these packets from being raided is this the principle task of the firewall?
Tomas Althen: You can say that in one sense. You also don't want packets to come in to your data system, or into your network, packets which you don't want to be there. You want to be able to decide for yourself as an organization or as a company: hey, I don't want these guys to be able to access my treasure. And to do that you need to do some filtering. You need to decide which packets are allowed, which packets are not allowed. You have to do that very fast so you don't end up with yet another bottleneck. And we solved that problem.
Host: Let's look ahead a couple of years and have you estimate for us how you see this technology evolving. What do you think will be different or new on the horizon in a couple of years? Tomas?
Tomas Althen: More and more has been put into smaller and smaller spaces. We are making quite a leap in putting all these features on one card. But the next step is clearly putting them on one chip. And we are talking to chip vendors to try to do that as quickly as reasonable.
They usually say that one year in this business is seven ordinary years. So, that would be 14 years from now. We'll see things more and more integrated. For Effnet, in two years I would s

A. The quality of being easy to use.
B. For most of us, broadband access is years in the future.
C. To maximize the Internet's sufficiency.

Mobile Phone and Diseases
A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said,
But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec(魁北克), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.
The study at Finland’s Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said.
“We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body,” Leszczynski said.
Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brain’s protective shield against harmful substances.
The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said.
The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的), he said.
“Increased protein activity might cause cells to shrink—not the blood vessels but the cells themselves—and then tiny gaps could appear between those cells through which some molecules could pass.” he said.
Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result.
“These are not life-threatening problems but can cause a lot of discomfort,” he said, adding that a Swedish group had also suggested a possible link with Alzheimer’s disease.
“Where the truth is do not know,” he said.
Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.
According to Leszczynski, how does mobile phone affect one’s health? ______

A. Mobile phone radiation can increase protein activities and such activities can make the protective shield more permeable.
B. Mobile phone radiation can shrink the blood vessels and prevent blood from flowing smoothly.
C. Mobile phone radiation will bring stress to people exposed to it.
D. Mobile phone radiation kills blood cells at a rapid speed.
