 Welcome to ITU Telecom World 2017 here in Busan in the Republic of Korea. I'm very pleased to be joining the studio today by Chi-Hung Lee, who is president and CEO of the Seoul Digital Foundation. So Lee, thank you very much for being with us today. It's my pleasure. Now I'd like to start off by talking about smart digital transformation. It's a question I've been asking most people who've been coming into the studio here. It's the key word, the theme here for ITU Telecom World. Perhaps you could tell us, what does it mean to you? Okay, so let me make it very simple. So digital technology is connecting people and things and space within a city. And cities are generating huge amount of data. Those data are collected and online to make a city smarter. In short, digital transformation is city becoming smarter using digital technology. Okay, fantastic. Now tell us a little bit about the Seoul Digital Foundation. What do you focus on mainly? Okay, so Seoul Digital Foundation is under Seoul Metropolitan Government. We work for a city of Seoul. We developed a strategy for the smart city. And also we are offering digital education for the city. And what are the key smart opportunities and challenges for Seoul in the next five years, let's say? We are investing lots of money to build a data network. We believe that the data network is the basis to make the city smarter. And also we are building up the capability to analyze data systems. So we much focus on data network and data analytics capability in the next five years. I mean, Seoul is a big city so there must be a lot of data coming in. Right. We are trying to combine the different source of the data into the one single platform. That is the most challenging but the most important thing. Sure. And how is Seoul managing public data for citizens? Okay, so we believe that opening public data is very important for the city. So we published important data on the website and mobile. And also we published very important but private sensitive information at a very close area. Where citizens are allowed to get into that place. They have access to private information. Then they can process them for their purpose. They can take the results to the outside. They are not allowed to bring raw data to the outside. And what kind of data are people most interested in? People and business are interested in the data such as personal transaction information. So the business can make a decision based on that information. Then they can forecast the sales also. Right. So in other words, people taking public transport, people using their mobile telephones, people using electricity I would imagine, all of these kind of elements as well. It's okay. Great. And how do you measure the smartness of Seoul? Can we talk a little bit about how is this all this data collected? Actually, we still don't have a specific guideline for the KPI for smart city at this moment. We are working on to have our own KPI. We believe that KPI shouldn't be the same to most cities because the city has their own priority. So we now much focus on the digital business side as well as the innovative public services. So we try to combine both into the one KPI at this moment. Okay. Great. And now you're here at ITU Telecom World. This is a key event in the ITU calendar. Why is it important to you to be here? And do you have perhaps a message to the participants here? Why? So the ITU, this event is very famous for the smart city readers. So I saw lots of people at this place. So it will be great for me to expand our network and share the experience with the readers. That is a great value for me. And also I like to communicate excellent in digital capability of the server to the world. Fantastic. Well, that's great. You certainly have here. And many thanks for being with us in the studio. And we look forward hopefully to catching up with you again in the future. Yeah, it will be great. Thank you so much. Thank you. Thank you.
