as demand from Japan hasn't recovered to the level before the March earthquake and economic recovery in the U.S. is still slow. The research firm also cut its forecast on revenue growth of the global semiconductor sector to 4%-5% this year, from 6%-8% previously, due to slower PC sales. It expects PC demand in Japan will return to pre-quake level next year, IDC added. problem is rooted in the 1990s and early 2000s, when not enough people went into the construction business. "The construction companies are able to recruit young, recently graduated people, but they also need experienced people who can manage projects," Tullstedt said. The industry has also seen large numbers of employees retiring in recent years, and there aren't enough experienced workers fill the void. The biggest concern right now is finding experienced project managers, engineers and technicians for civil construction projects, and the problem may be most pronounced for larger companies, such as Peab AB (PEAB-B.SK), NCC AB (NCC-A.SK) and Skanska AB (SKA-B.SK), which are active in civil construction and need to keep their market shares despite retirements and staff turnover. Peab's chief financial officer, Jesper Goransson, recently told Dow Jones Newswires in an interview that there has been competition for human resources for some time now, but he didn't want to say whether the company had been forced to refrain from bidding for contracts because of capacity constraints. "We don't see it that way.

"In this reality, we are obligated, as a security force, to expect all possibilities and various scenarios, and prepare accordingly. This is a national mission and a national challenge," Danino told the paper. Another official said the army hopes to avoid civilian casualties but would set "red lines" for the demonstrations. That means Israel will not allow demonstrators to burst across the borders during the coming week's protests -- as they did on the Syria-Israel border on May 15 -- or to enter Jewish settlements in the West Bank in September. He said Israel will not react to nonviolent demonstrations, including large gatherings near the settlements, but that it would be forced to take action in "life-threatening" situations. On May 15, the day on which Palestinians mourn the anniversary of Israel's founding, hundreds of demonstrators in Syria broke through the frontier and entered the Israeli-controlled Golan Heights, while in Lebanon, large crowds converged on the border. Some 14 protesters were killed in clashes with Israeli soldiers, who were
