First, the mega-mat foundation construction technologies are shown, including ultra-low heat concrete, heat of hydration control programs, and the logistics plan. Then, high strength concrete technologies of 50~80 MPa are introduced and discussed within the context of the highest pumping record in Korea at 514.25 meters. Structural design concepts of gravity load and lateral force resistance systems are introduced, along with surveying systems using GNSS and temporary installation plans of special heavy equipment like tower cranes, hoists, and high pressure concrete pumps. -

Shanghai, China Overview Introduction
Shanghai, China Overview Introduction The name Shanghai still conjures images of romance, mystery and adventure, but for decades it was an austere backwater. After the success of Mao Zedong's communist revolution in 1949, the authorities clamped down hard on Shanghai, castigating China's second city for its prewar status as a playground of gangsters and colonial adventurers. And so it was. In its heyday, the 1920s and '30s, cosmopolitan Shanghai was a dynamic melting pot for people, ideas and money from all over the planet. Business boomed, fortunes were made, and everything seemed possible. It was a time of breakneck industrial progress, swaggering confidence and smoky jazz venues. Thanks to economic reforms implemented in the 1980s by Deng Xiaoping, Shanghai's commercial potential has reemerged and is flourishing again. Stand today on the historic Bund and look across the Huangpu River. The soaring 1,614-ft/492-m Shanghai World Financial Center tower looms over the ambitious skyline of the Pudong financial district. Alongside it are other key landmarks: the glittering, 88- story Jinmao Building; the rocket-shaped Oriental Pearl TV Tower; and the Shanghai Stock Exchange. The 128-story Shanghai Tower is the tallest building in China (and, after the Burj Khalifa in Dubai, the second-tallest in the world). Glass-and-steel skyscrapers reach for the clouds, Mercedes sedans cruise the neon-lit streets, luxury- brand boutiques stock all the stylish trappings available in New York, and the restaurant, bar and clubbing scene pulsates with an energy all its own. Perhaps more than any other city in Asia, Shanghai has the confidence and sheer determination to forge a glittering future as one of the world's most important commercial centers. -

Vertical Transportation: Ascent & Acceleration
Tall Buildings in Numbers Vertical Transportation: Ascent & Acceleration As part of a recent collaboration with the Guinness Book of World Records, CTBUH certified that Shanghai Tower has the fastest elevator and the longest elevator run of all commercial buildings in the world. Expanding upon this study, CTBUH sought to determine the records for speed and length of run among the world’s tall buildings. The findings and related data are displayed here. The World’s Five Fastest Elevator Installations* Key 615 m 600 m Length of Elevator Run Distance Traveled = = (may include fl oors 504.9 m in 30 seconds below ground) 375 m 318 m 20.5 m/s 20.0 m/s 16.83 m/s 12.5 m/s 10.6 m/s Shanghai Tower CTF Finance Center Taipei 101 Landmark Tower Two International Shanghai, 632 m Guangzhou, 530 m Taipei, 508 m Yokohama, 296 m Finance Center Hong Kong, 412 m *The speeds shown are maximum vertical speed achieved during the run.

SYNOPSIS : Modern city have had a lot of high-rise building in high standards and multi-level performance. Using of city space reach better stages by using integration. These skyscraper have increased working load on ground. that building is efficiently designed for that soil capacity is well applied. With material side, big size pile, high strength concrete and high strength steel is used for that getting enough lobby space and resisting load increased of high-rise building. limit load test and load transmitted test can make soil capacity optimized. By the way, method of measuring pile capacity is more advanced and bigger. pile type applied by high rise building have underground excavation space, also reflect regional soil property and have some fact reviewed. A lot of high rise building recently is built as land mark in Seoul, Busan and Incheon. about method of measuring capacity of foundation pile, example of construction field is compared and reviewed. Key words : pile toe load test, high-rise building, bi-directional pile load test, pile load test 1. -

Contemporary South Korea: The Uniqueness of the “Han River Miracle” Greg Scarlatoiu Executive Director Committee for Human Rights in North Korea (HRNK) October 2, 2014 Korea’s Economic Status: Take-aways • Korea is an economic powerhouse, the world’s 15th largest economy • Korea achieved extraordinary economic success, going “from rags to riches” over only a few decades. This process took others two centuries. • The U.S.-Korea alliance was key to Korea’s economic success. • Koreans achieved this extraordinary economic success through hard work, bold entrepreneurship and innovation. The “Han River Miracle” is a source of great national pride. • Trouble on the Korean peninsula is likely to have a cataclysmic impact on the world economy. • Korea’s economic status has a significant impact on Korea’s restrained and responsible behavior as a nation-state.
