that they have hope and as long as they can do that and as long as they have encouraging signs, like the knocking sound that they've heard, then we will continue volunteers at the safe side community center, giving what help they can just a vive as, as the tense wait for news of loved ones continues. people are starting to demand answers. the new york times is reporting that an engineering assessment in 2016 detailed structural failures in the building. the building managers were still shaping plans for a repair project that was set to get underway. quote soon, but those trapped under the rubble. it was not soon enough. well, joining us now on the phone as audra as using the meaning. he's the director of the florida international university school of construction. we can't see him right now, but he is actually sending next to this collapse. building in miami doctor is using the meaning. i'm going to start with what is perhaps the most obvious question. how

could something like this happen? this is the one of those, you know, accident that happens. the do not know exactly what the cause or causes of. this is a day number 3. so morning formation is becoming available. but it's gonna take probably months, maybe yes, to put the pieces together. and so i, so i didn't find the main cause or cause at this point, you know, we have lots of information becoming available by all probably what the investigators on setting up their thinking, all those into our accounts. but if it is right now it's, it's pretty much what to say that exactly what the cause of cause. we heard in the report just now that engineers raised concerns about major structural damages on the building years ago. does that mean in your opinion, that the collapse could have been prevented? that's one piece of information that has become available. i have not read that

report. very detailed, but i have seen parts of it. so that particular reports, the parts of the diagram was related to the swimming pool, but i do not know exactly where the swimming pool is located with respect to the buildings. again, that's just the one piece of information. there are some other pieces of information that the study was conducted a few years ago. the gong, the sampling, the city that have been reports of the many heavy construction material stored on the roof of the building that has been report that has been happening. engineers have reported that the cracking in the basement so on. so these are all different factors that you have to take a look at it. of course they can contribute, but you cannot at this point say, any one of them where the, the main reason for,

for this class. sure, you yourself are not involved directly in this investigation. but what can you tell us about how structural engineers approach cases like that? like i said, this is a rare accident. but social engineers, i mean there has been some other collapses and there is a very set procedures for investigating. so you look at every pieces of information that may be attached to this from design plan design calculations, construction notes. they will be taking notes of david taking the samples of the steel and the concrete. went into building this building, making sure that that matches the design assumption that going to designing this thing. the computer simulation modeling to sol building. we have the knowledge and

we have the tools to simulate numerically actually through the very detailed analysis, the sequence of the collapse, the same way you saw on the video that that's being captured. so once you do that, then you can pinpoint exactly what the cause of cause of this is going to take some time, maybe yet, but in this to get so they're going to release the formation as they become available. especially if it's related to the safety of similar buildings. but one thing that i believe that we need to do is show the inspection. i didn't need to be done more frequently. and this was the, the way i just start shop inspection was done in 40 years, 40 years, the, to me a full long day too long. and the one of the counties here have found the law that after the 1st for the inspection, then you do every 10 years,

but the fit for the as you have to do more investigation. all right, agile rod as easy. now me in miami, thank you very much for your analysis. you but thanks look will say in the united states because former police officer derrick shelven has been jailed for 22 and a half years for the murder of george floyd, the victim's family. believe the sentence is not enough. the judge says he base the term on show and abuse of his position and the cruelty he showed to his victim. but the world's gaze was fixed on minneapolis. court house. outside emotions were high on the sentencing day. in a case that had triggered traumatic memories, of many other cases of police violence in the u. s. george floyd's family called on the court to send a message. every day, i have been the justice to be served, re live in the execution of george mason that please plan is to forgive us to show

them the maximum of soon as possible. shelving remained silent during his trial, but now he addressed his victims. family. want us in michael's as a court family there's going to be some other information in the future that would be of interest. and i hope things will give you some some peace of mind. there was silence on the streets outside and as the judge read out his ruling. and i want to acknowledge the deep and tremendous pain that all the families are feeling, especially the void family. the court committed to the cause, the commission of corrections for a period of 270 months as to $70.00. also, the judge added that he was facing the sentence on the law and not public opinion. but the question everyone was asking is 22 years enough for show vins crime

for some, the sentence represented accountability, but now they will focus on the other officers involved employees, murder. but his family is outraged. 22 and a half years is not enough. we will serve the life sentence. we can give george back. the murder of george floyd created anger and gave rise to one of the u. s. largest ever civil rights movements. one man has now been convicted for that crime . in many other cases, remain unresolved. these activists believe that in the us, justice has not yet been served law time now for a look at some other stories making headlines around the world today. police and turkey a fire tear gas to break up a pride parade. some 20 people were arrested at the rally and assemble, including a prominent photographer, l g, b t q groups accused the turkish government of encouraging violence against

a vulnerable community. 3 members of doctors without borders have been killed in ethiopia as war torn t grier region. at least a dozen aid workers have diets and fighting broke out last november, the 8 agency says its staff are brutally murdered. the u. s. government has released an eagerly await report on unidentified flying objects. the federal government is unable to explain as many as 143 objects encountered by military aircraft in the last several decades despite speculation. social media and the report does not suggest aliens might be behind the sightings, but it does say that identifying the object or phenomenon may be beyond this thing mean of the american military. and the w reporter aaron tilton, has been following the story for us. you f o seem like a notion from sci fi movie,

but to the us government. this is serious business isn't it will, of course, is the matter of national security because according to the government, they've detected well, 143 different objects that they couldn't identify. zipping around in their airspace over the last 2 decades and for them to think about national security. because at the end of the day, these are objects, if they do actually exist, which could be put in military life, losses and buildings life in danger. and you have to realize they're not the only country actually looking at right now. china and russia, you cave and seeking as well also admit that they've had that they have programs working in the business. if you are trying to figure out what these objects could be if they're cited and at least in the u. s. context, this has a tradition which goes back to 1952. that's when they 1st open their 1st project called product blue book, which is looking at the existence of your votes for them for the american military . it's a very serious issue and one that has to deal primarily with national security. the internet loves a good phone story, but why has this report in particular,

sparked so much interest online? well, i mean, partially, it's because even though, as i was saying this is an issue of national security for the military. when we hear you are foes, a lot of people are conditioned to think that there's a little green man, a somebody from another planet city and then trying to thing around. and unfortunately, that's just not the case. i mean, are you for basically just something up there that we don't know what it is? so, you know, because that association people gets start speculating very, very quickly at the same time. it has to do with the observers to a certain extent. these aren't just some like country local claim that they were abducted by aliens. rather, these are well trained military pilots who are trained to keep their cool know what they're looking at in. also you have to remember they're flying some of the most sophisticated insensitive observation planes that have ever existed in the history of humanity. so i think you have kind of like a double punch there, like a one to whammy where you're having some really interesting phrase israel like you f o is combined with some really high quality observers. and it's just kind of creates a perfect clip, b type situation for,

for the internet. what could be behind these signing? well, that really is the big question. the report itself did not mention extra drills at any point, of course have to throw that out there. right from the get go. instead, people are speculating. these could be some type of sensor errors. it could be problems with the cameras. still others, especially the authors of port, seen that there are actual physical objects. 243 sightings. that was actually something physical physical in the air. so that has some speculation. i'm pointing to certain drone technologies. now we know other countries are looking into supersonic drones, which can fly many times faster than the speed of sound. and we do know that russia and china in the us itself, are looking at drone technology. so some people are speculating that this could be some type of new military technology that we just haven't seen yet. and while personally, i would love to have this report actually say we're one step closer to she can unfortunately, i think the real answer is going to be a bit more terrestrial. all right, there, until then. thank you very much for the details on the story. thank you. you're

watching t w news coming up next to our digital technology show shift. i will be back with more as a call to the thank you so much for watching the news every day for us and for our planet. legal ideas, it is on its way to bring you more conservation. how do we make cities greener? how can we protect animals and their habitats? what to do with all our waste? we can make a difference by choosing reforestation over deforestation recycling over disposable

martin solutions overseas. our ways are, is truly unique and we know that, that uniqueness is what allows us to live and survive. why dia, the environmental global $3000.00 on d, w, and special . how block chain is revolutionized in the financial system in the philippines, lima, as i said, is an entrepreneur from germany and an expert on crypto currency. she's traveling around the philippines to meet people who use block chain technologies to provide everyone with access to financial services. mm

the cleaner the current open source to the people that were not involved in financial actions. there are a lot of, i'm bank people, people that then have no access to services that we would take for granted. like insurance, saving money, borrowing money, just planning ahead further than the day that they live because they only have money for that they. they are living actively the me i bought a lacrosse and that that i need to be blended them and that it's not that i'm putting them down and i'm putting them fair that

1000. i'm but put me on a 1000 to 2 months to pay for your pain jane to them and then putting them up by the end. then i learned, i learned since i've been alone. benign jelly, i don't, i don't need to see them. i was going to be begun when i'm on the phone. i mean by mother of the guys nursing mama, last name is la . the

people thought that above boucher i believe maybe get maybe getting them you know mr. young was on telecom for you know, there are a lot of over still work from the philippines going to other countries because they can earn more there than they couldn't be. so even though their salary compared to the global standards is really low, even overseas. they can send it back to the philippines

the uses that they pay really high fee, just to remove the money to their families at home. where currency comes in and technology comes in already, is that they can send back the money with crypt currency. their family can exchange it in tom shops where they, where they live and the fees are so much lower. and that is something that is already happening today and that is just going to develop and improve, i believe average amount that the filipino sent home is $200.00. they'll be $20.00 out of that to get that money for their family.

is really a decentralized financial system. doesn't need a government. it doesn't have central authority. if interoperable it's global, it's borderless. basically, it's an option for people who are excluded from the existing system where people can send money from anywhere in the world, things affiliate using different. yeah, so a normal overseas for worker wouldn't know how to use going. and you know, that was one of the 1st challenges we had and what we did was we partnered with similar services based in canada or south 3 or hong kong or singapore. and what

they did was they provided up the 1st mile for communities that have been a communities that have been overseas workers. they will just basically advertise a cheaper, faster way to send money to the philippines, making the bit going by invisible. so using bit by and as a platform, we were able to provide a service where you could just easily sign up, make an account, putting the amount you want to put in, put in the pickup option delivery option. and then i choose the fun shop. and it's done like i've sent money basically $20.00 from anywhere in the world through the philippines. and i can go downstairs from the font shops, pick it up. soon as i get this text message or email,

the benefit of being, there's 15000000 people younger than that 24 envelope. and they are tech savvy. they're not afraid of technology. they're not afraid of the initial world. they kind of don't trust the banks. it's kind of like brewing, you know, like we say like a perfect storm for this kind of technology to take hold that was being used for fraudulent activity, for sake investments games for these games and just for scans because it was easy for the people. there was the height, there is excitement, not a lot of knowledge, but hope of being put into it. so it doesn't only attract good people with bad

people as well. that them can make a lot of money out of that. that is not, you know, that is just a very small part of the space that doesn't reflect this, this technology and what the technology can do. me a way to doc chain works as opposed to a centralized system, is that the information data and control is not in the hands of a centralized entity but is distributed and called the nodes all over the world. the nodes are handled independently and anybody that has enough computing cars, syria could run a node, meaning anybody could take part in the process of verifying transactions, building block chain. oh,

this is where the big difference. nice because the par and the show is given back to the people i guess the plastic bank has launched a block chain based banking application for the poor, an opportunity to use plastic as money, individual collectors that would otherwise sell to a middle man who then sells to another middle man and remove the middleman. and then we transport directly from the hands of the collector to the recycler, all of the extra value that was going to all those middleman are now shared amongst the collector use. there's a powerful roadmap ahead for the plastic bank in the applications including financial

inclusion, credit rating that service. and the app in this community is used not just to register the collector, not just to give a sense of identity, but to give a transaction history. to give the collector an opportunity to have authentic value exchanged into their account, it allows her to have a savings account. it allows her to be free of cash. how powerful to look into a bank account now and see that you actually have value. our mobile phone veneration is over 100 percent. and one of the fastest growing in

the world. instead of making people go to the let's just put banking into their hands. the not the bank, so we need the bank by putting the bank in the smartphone. it's so much more accessible. we want everybody to the benefits and by connecting our app to the existing systems, you know, it makes it, it makes that transition easier. and it makes people adopting that because you are using this kinds of apps, not that scary. and eventually the goal would be like, you know, if the apps are really useful and if they work, then you don't need to convince people. think you're working, you're doing the pioneer work there because you're may be struggling with the image

that locks into a cooper kinds. the is this disruptive kind of thing that endangers traditional business, where you're doing by working together, sort of working against things you're doing very important. i believe block chain technology will fundamentally change the way our society works. in the long run, it will enable new processes. we can't think of right now, but the option is there. what i can do is i can include people can narrow down the gap between rich and for me this is the show for africa.

my jersey is 77 percent this time our st debate comes from come on in germany. our focus is on everybody's talking about africa stolen or the when will it finally be returned to hold of that needs to be brought back to the 77 percent. that shows that the issue is changing the continents. the news africa was gone. med what's making the headline? what's behind the way on the street to give you enough reports and insights. all the trends. my talk to you in 60 minutes on the w. ah.

what matters to us me that's why we listened to their stories reporter every weekend on d. w. hello and welcome to another edition of the 77 percent. this is the show for africa. majority the youth like you and i, eddie micah, julia is the name and i'll be driving you through the program. this week, our focus is on art. let's check out what we have for you on the show. st to be fixed as we use it in germany to discuss what happens with that for some assets then we'll meet africa.
