Hi Yuya, There should be no problem to use the Apache Kudu logo in your conference slides, assuming you are just using as intended to describe or refer to the project itself. This is considered "nominative use" under trademark laws.
You can read more about nominative use at: https://www.apache.org/foundation/marks/#principles Thanks for including Kudu in your upcoming talk! I hope you will share the slides with the community.
