It also bore some telltale characteristics of terrorist attacks, such as the fact that there was no obvious cause of the collapse. An internal explosion, perhaps from a terrorist bomb, would have accounted for why the building fell, but upon investigation, it was revealed that there were only small fires fueled by gasoline from cars in the parking garage as opposed to the huge infernos that usually accompany bomb blasts. Sampson) Also, the debris from the structure fell straight down instead of outward, like an explosion would have caused, so a terrorist attack was quickly ruled out. (Superstore Collapse) With this news, investigators would need to look to the structure itself for answers. The building was constructed in the late sasss and was completed in 1989. (Mclean, Anderson, Petersen, Del voice) It was originally planned to be an office building, but late in construction, the owners opted to change their structure into a department store-a fact that would later prove to be vital to the case. Superstore Collapse) The building was built on an old landfill site, so the integrity of the foundation was obviously suspect to failure, but after in depth testing, it was revealed that the alluding had a solid foundation that remained in place and did not fail. (Mclean, Anderson, Petersen, Del voice) Investigators began to research into the history of the structure, which they learned had originally been planned as office space. The sasss were booming for South Korea. Their economy was rapidly growing, and Seoul was to host the 1988 Olympic Games. (Mclean, Anderson, Petersen, Del voice) The combination of these two factors led to a boom in construction in the late sasss (the era that the Sampson Department Store was constructed) that was too great for the builders of Seoul to Andre, and since international construction firms were not allowed to sign contracts, the firms in Seoul were overloaded and as a result, many buildings had cut corners and were less than desirable. Mclean, Anderson, Petersen, Del voice) to build the entire office building, but after Sampson executives proposed drastic changes in the plans, the situation was complicated. The owners of the building decided they wanted to change the building into a department store, which meant they would need escalators on each floor. This meant cutting into the main columns supporting the structure. On top of this, they wanted to add a fifth floor to house a skating ring, to which the Housing crew refused, saying that the building wouldnt support the changes. Superstore Collapse) They were fired and an in house construction company was hired to finish the Job. They carried out the changes, and accidentally MIS-aligned the columns on the fifth floor with the columns below, so instead of the weight being shifted straight down the columns and into the ground, the weight was shifted across the 5th floor and down to the fourth floor columns. (Superstore Collapse) The building was changed to a department store, with awakened columns and the added load of a fifth floor. Mclean, Anderson, Petersen, Del voice) On top of this, Sampson executives changed their minds again later, changing the top floor into 8 traditional Korean restaurants instead of a skating ring. Since Korean tradition is to eat on the floor, the floor had to be thickened by 4 feet to allow for heavy heating elements, which pushed the building dangerously close to its limit. (Superstore Collapse) The faults were adding up and pointed to a general disregard for building codes and safety, but there was still no definite answer for what caused the collapse until a reengineering discovery was made. Three 1 5-ton air conditioning units on the roof (which was of insufficient width to hold that much weight) (Mclean, Anderson, Petersen, Del voice) had been re-positioned some 2 years earlier. Standard practice would have been to hire professionals with expensive cranes to lift the units, and gently set them down into their new positions, but in order to cut costs, they were placed on rollers and dragged across the roof. (Mclean, Anderson, Petersen, Del voice) This caused an enormous amount of weight to shift across the whole roof, causing tress, fractures and huge visible cracks throughout the concrete slab. Mclean, Anderson, Petersen, Del voice) After vibrations from the badly placed air conditioning units caused the cracks to widen over the years, the building finally reached its breaking point on that tragic day. The Sampson building had been planned as office space, but late in construction, executives decided to change the building into a department store. After firing Housing Construction for refusing to carry out the changes, an in house construction company was hired. The columns were weakened to allow for escalators, ND the columns added to the slab above the 4th floor were not aligned with the columns below. The heaviest floor in the building was added on top of these MIS- aligned columns, and on the roof, the heavy air conditioning units. After they were dragged across the insufficient roof, huge fractures in the slab should have warned Sampson executives that they had a problem, but instead of taking action, they simply ignored the huge structural flaw for 2 years. For 2 years, every time the air conditioning units turned on, workers reported feeling the whole building vibrate; Hess vibrations caused the cracks in the roof and 5th floor slab to widen around the MIS-aligned columns. Oases coming from the upper levels of the building, but he took no action. Workers reported huge cracks in the fifth floor slab that had formed overnight and the sagging ceiling that morning, but instead of closing the whole building, only sections of the fifth floor were closed. (Superstore Collapse) A meeting was held behind closed doors between the building owner, the structural engineer who oversaw const ruction of the building and the store manager. Superstore Collapse) The engineer urged the en to close the store immediately for urgent repairs, as he believed the building was in danger of collapse, but the men ignored his warnings (although they themselves were allowed to go home early after that meeting). A few hours later, at about 5:50 p. M. , a powerful showplace shook the whole building. Workers sounded alarms to evacuate the building, but by now it was too late. At 5:57 p. M. The roof around the air conditioning units gave way, and the air conditioning units crashed down onto the already overloaded and weakened 5th floor. This caused each floor to pancake down onto the floor beneath it, and in 20 seconds, the building had gone from a 5-story superstore to a pile of rubble with almost 1 500 people trapped inside. This event shook South Korea to the core, where intensive building code modifications were made. It was discovered that 14% of Korean buildings were unsafe, while 84% needed repair work. Only 2% of the buildings in Korea were up to par with the new building codes. The Sampson Department Store was only one of the 14% of the buildings in Korea that were unsafe at the time, and this event brought that into the publics eye.

The Amazing Sixth Sense essays

The Amazing Sixth Sense essays With obvious gifts for directing children, creating atmospheric stories, and working honestly with deeply felt themes about the role of the dead in our lives, writer-director M. Night Shyamalan has followed up last year's touching Wide Awake with an even better film about a boy in the grip of loss and fear. Bruce Willis stars as child psychologist Malcolm Crowe, who is shot by a former patient who claims Crowe did nothing to alleviate his supernatural childhood terrors. Months later, Crowe is a changed man, isolated, remote from his wife (Olivia Williams), and quietly bent on helping another boy named Cole (Haley Joel Osment) who seems to be undergoing similar traumas to that of the gun-wielding assailant. For most of the film, young Cole seems like a sharp but terribly frightened child, his slight frame a natural metaphor for an inability to cope with some awful, invisible force in his life. He tells Crowe he has learned to deflect the worries of his single mother (Toni Collette) by drawing happy pictures instead of the horrifying ones he actually sees, and he has even made a deal with a local bully to pretend to be his friend. Crowe sees through Cole's facade, but it takes a long time before the boy reveals what's ailing him: he has an unwanted gift for seeing the dead, particularly those who have died violent, unjust deaths and seem to be seeking him out. While The Blair Witch Project is more primal in its suggestive scares, The Sixth Sense has an old-fashioned Gothic touch that Shyamalan uses with effective economy. For most of the film's running time, all the director really needs to do is frame certain shots with an airy anticipation and throw in a few evocative details: chilled breath, leaves blowing along a street, the hint of a spectre rushing past a doorframe. (Interestingly, Cole often seeks refuge in a makeshift tent in his room, which ends up amplifying his and our fear in much the same way as in Blair Witch.) By ...
