 The greatest challenge is to, several, but first of all, I think is to challenge itself, challenge the success of the area itself, to implement or to actually to achieve the change that the management and staff have identified. For instance, we identified one area that needs particular attention, that is the quality assurance. Quality assurance are in a broad sense of risk management of the institute. We identified that as a priority area. Now, you might say, after such a successful institute for 45 years, how can you say that you have not had a quality assurance? Yes, we have had. Yes, we have done produced quality research. But in the meantime, we must confess that there are areas, documents are not properly stored, data not properly managed. We must address, we must establish a system. And this is one area that I have not done enough during my tenure to address it. And I regret really, I feel sorry that this is something that I should take responsibility also. I have not done so well after seven years. So, you see, this is a challenge. We have to face it. Let's face it. It's a challenge. And after 45 years, many NRS still feel there is no mechanism in HR in human resource management, which allows married based professional growth. I mean, isn't that strange after 45 years? We have to be brave to admit that there are such challenges. So, agree and identify challenges for the institute itself first. And then secondly, is to mobilize resources to achieve the goals that we have set for ourselves.
