New solar-powered street lamps were featured on the main 8pm evening news on North Korean state TV this week.
The solar panel and battery combo that powers the lamps was developed by Kim Chaek University of Technology and was introduced by an associate professor at the university named Cho Hyon Ho.
From the images, it’s possible to see a plate explaining the solar cell is based on a Cadmium Telluride (CdTe) compound. Here’s what Wikipedia says about such solar cells:
CdTe is used to make thin film solar cells, accounting for about 6 percent of all solar cells installed in 2010. They are among the lowest-cost types of solar cell, although a comparison of total installed cost depends on installation size and many other factors, and has changed rapidly from year to year. — Wikipedia, “Cadmium Telluride,” accessed February 10, 2013.
There are some shots of the lights installed outside. The technology behind the development isn’t particularly advanced, especially compared to the solar panels being produced in Japan and China, but the frequent power failures in North Korea could make this an important domestic technology.
Here’s the report and below it, some stills.
North Korea is continuing to strengthen its ranks of elite hackers and could have up to 3,000 of them, a North Korean defector said in Seoul on Wednesday. (Update: New information below)
Kim Heung-kwang, a former professor at Pyongyang Computer Technology University and member of the North Korea Intellectuals Solidarity group, told a cyber security conference that North Korea likely has around 3,000 hackers, according to local news reports.
The state previously had around 500, but raised the number last year when the cyber warfare unit saw its status raised, Yonhap reported him as saying. The unit sits under the Reconnaissance General Bureau.
Kim told the Joong Ang Ilbo that students with computer skills are identified at a young age and sent to a middle school in Pyongyang where those skills are further developed.
The students then progress to Kim Il Sung University or the Kim Chaek University of Technology and some are even sent abroad to perfect their skills, he told the newspaper.
Kim said North Korea realized that building the ranks of cyberwarriors “costs less money than to train Army or Air Force soldiers.”
He said North Korea uses IP addresses from China for its attacks, making them difficult to trace. – The Joong Ang Ilbo, June 2, 2011.
North Korea has been blamed for a string of recent cyber attacks against South Korean banks, companies and government institutions.
Earlier this week, the South Korean military said it believed hackers in North Korea had sent e-mail messages containing malicious attachments to around 60 graduates of a military school. The extent of that hacking incident and the damage are still being evaluated.
Update 1: The Daily NK has more details from the cyber security conference, including details of North Korea’s supposed hacking center and its location. The online publication quotes information from an unnamed defector, who didn’t attend the conference out of fears for his safety.
According to the report, the hacking center is called the “No. 91 Office” and is located in a two-storey building in Dangsang-dong in the Mangkyungdae-district of Pyongyang. He defector claimed to have been inside the building several times.
In 2006, the center had a staff of about 80, all in their 20s and 30s with the exception of the leadership. The staff came from Kim Il Sung University, Chosun Computer University, Kim Chaek University of Technology and other elite schools. They frequently spoke of travel to Shenyang and Dandong in China.
An affiliated trading company, “May 18th Trading Company,” obtained equipment needed for the No.91 Office to carry out its work.
In mid November the North Korean state media carried stories about the inauguration of a new distance-learning network. The reports expand on a brief bulletin issued in early October about the start of an “online lecture” service.
The network is based at the Grand People’s Study House in Pyongyang and connects to centers of learning throughout the country, including local people’s study houses, libraries, scientific centers and educational institutions, according to the reports.
The distance-learning application works on any operating system, said KCNA. That most likely points to a Web-based application, but it could also mean a more complex set-up based on Java or applications for Windows and Linux. Real-time images, audio and documents can be shared via the network, which is connected by optical fiber:
People’s study houses in different provinces including Jagang and North Hwanghae provinces and libraries in cities and counties have already made full arrangements for receiving distance lectures from the Grand People’s Study House by use of high-speed information system provided by optical fiber communication. This has paved the way for putting the people’s educational system on the latest science and technology.
The DPRK began installing a nationwide fiber optic telecommunications network in 1998 with funding support from the UN Development Program.
The network also collects lectures into a database for call-up on-demand, the KCNA report said:
Thanks to the establishment of the new distance lecture system which puts main emphasis on the lectures based on real-time dialogue while providing the subscribers with opportunities to review what had been lectured anytime necessary, working people and students across the country can receive distance lectures in diverse ways according to their study plans.
The new network was inaugurated by the Grand People’s Study House and the Joint Information Institute of the State Academy of Sciences, according to KCNA.
It’s not the first time media has reported such a system in North Korea. Kim Chaek University of Technology started a similar system in January 2007, according to a KCNA report from the time.
Pyongyang, September 12 (KCNA) — General Secretary Kim Jong Il provided field guidance to the Manpho Unhwa Factory alive with the dynamic drive for pushing back the frontiers of latest science and technology.
