Today (19th), the ninth day of the accident, the search operation started at 7:30 in the morning.
However, there is no news of further rescue of the remaining missing persons.
Eight rescue dogs have been dispatched since this morning to search for traces of missing persons in debris and yards near the accident site.
A total of 205 people and 51 equipment were also put into the site, and we plan to remove the risk factors by gradually removing debris such as reinforcing bars located on the 22nd or higher floors.
State-of-the-art equipment, such as endoscope cameras and video detectors, is also used for search operations.
Continuing from yesterday, work is also being done to reinforce the wire to dismantle the tower crane that leans precariously next to the building.

Are the investigations continuing to reveal the cause and responsibility of the accident?
<Reporter>
Yes, it is. The police have been working with the Ministry of Employment and Labor since this morning to search and search the Hyundai Industrial Development Headquarters and Gwangju Seo-gu Office in Yongsan-gu, Seoul.
It has been five days since the search and seizure of the Gwangju apartment collapse site office and the supervision office.
The police are also investigating the situation where some of the concrete samples suspected of 'bad health' have disappeared.
To test the strength of concrete before pouring, a sample is made and the sample must be stored for 28 days.
The police are checking how the concrete samples were not found.
