SOFIA http://www.grizzliesprostore.com/kids-brice-johnson-grizzlies-jersey/ , May 18 (Xinhua) -- Representatives of various Bulgarian institutions here on Monday urged the government to develop and implement a comprehensive approach to protect children on the Internet.
"We want to have a national policy, a structured national approach, in order to be assured that our children will get on the internet a lot of what is useful and will rarely face those things that are harmful and dangerous," Georgi Apostolov, coordinator at the Bulgarian Safer Internet Center, told a roundtable organized by the Ministry of Transport, Information Technologies and Communications.
Children cannot be completely isolated from the dangers online, but should be prepared to face them, Apostolov said.
The fight against child pornography and pedophilia is crucial in introducing a comprehensive and structured approach, he said.
However, counseling is not less important because more than 90 percent of the problems were caused by underage persons to underage persons, such as fake web pages containing degrading information, Apostolov said.
Research of latest trends, along with training of children, parents, teachers, social workers and police officers, and implementation of legislative initiatives were also needed, he added.
Kalin Kamenov, Deputy Minister of Youth and Sports, said according to the EU Digital Inclusion and Skills report, over 80 percent of Bulgarian population had low or no digital skills.
Therefore, he said IT companies should train teachers, IT students could help in schools, and that a national information campaign be launched for parents about the importance of digital skills for their children.
Meanwhile, Orlin Kouzov, ICT expert at the Ministry of Education and Science, said the integrated approach required the active participation of all stakeholders such as teachers, parents, NGOs and government.
Digital campaigns on social media platforms "would reach many more people and be more durable than if taught in a special class on these topics," Kouzov said.

ATHENS， Aug. 28 (Xinhua) -- Lacking funds partly because of the debt crisis， Greece which is rich in underwater antiquities， is now working closely with archaeological groups from other countries to explore， preserve and display the treasure trove.
Located in the heart of the old town of Athens， stands the Ephorate of Underwater Antiquities (EUA). This elegant building of neoclassical style houses almost all of the antiquities discovered in various bodies of water in Greece -- sea， lakes and rivers.
A wealth of statues， urns， busts， coins and other remarkable findings are painstakingly cleaned and preserved here， before they can be exposed to the public.
Founded in 1976， the EUA is a special subdivision of the Greek Ministry of Culture and is tasked with the preservation of underwater antiquities.
The recession in the last few years has struck the EUA hard. It is now working closely together with other countries. Archaeological operations include islands such as Delos， Ikaria， Naxos， Skiathos and Crete.
The most famous underwater excavation currently in progress is the Antikythera wreck. Dating from the second quarter of the first century BC， this Roman shipwreck was discovered by sponge divers off the Greek island of Antikythera in 1900.
Found in the wreck were numerous statues， coins and other artifacts， as well as the remains of the device commonly considered to be the world's first analog computing device， the Antikythera mechanism.
Since 2014， the EUA has been collaborating with the Woods Hole Oceanographic Institution from the United States. The team completed an underwater circumnavigation of Antikythera， documented several isolated finds， relocated the Antikythera wreck， and identified a second ancient shipwreck， a few hundred meters south of the wreck. The Woods Hole Oceanographic Institution supports the EUA both on equipment and know-how.
"The water (in the wreck) is very deep， about 50 meters， hence we can't approach the underwater findings via conventional diving. It requires technical diving， which few of those employed in the Ephorate are familiar with，"Angeliki Simosi， the archaeologist and head of the EUA， told Xinhua.
The laboratory staff of the EUA is working on a number of findings， including the bronze head of a youth， a spear from the Antikythera wreck， and numerous urns.
"I'm standing before a bronze statue. It is a cuirassed rider of the late Hellenistic Period. It was found at sea between the Kos and Kalymnos islands. You can see how remarkably it has been preserved by the EUA's staff. See how wonderfully made is both the cuirass and the tunic of the rider，" Simosi told Xinhua， presenting the most impressive recent finding of the EUA.
As the laboratory gradually became overcrowded with new finds， the EUA recently acquired a second laboratory. There， findings from the shipwrecks can be desalinized， also known as scaling， which means striping salt and other excess material accumulated on the object's surface and interior over the years.
"The most important stage in the preservation of underwater antiquities is the process of desalination. It is a time-consuming process， during which all incoming findings are placed in water tanks. This process can take up to a year. The time needed depends on the volume of the object involved and how extensive the scaling on the object is，" preserver Spyridoula Papanikou， who has been working with the EUA since 2007， told Xinhua.
Preservation is a long and often arduous process. Papanikou showed a process of mechanical cleaning for an urn found in a Mycenaean shipwreck. "We must slowly remove all the scaling and finally reach the original surface of the urn， using either a scrapper or a pneumatic tool，" she said.
Fellow preserver Theoni Dimitropoulou shared another.
