Seminar

Today I went to the University of Tokyo to give a seminar.

As it happens, today was a day for the announcement of those who passed the university, so there were many students.

I thought that youth and vigorous energy were nice with a feeling of "shinmiri."

"Shinmiri" is a word that represents a deep feeling or a loneliness feeling.

In the seminar, I presented the results of my study to university teachers and companies.

Since I could get various questions and opinions to my study, it was a very nice opportunity for me.

I will do my study more from now on.

セミナー

今日はセミナーをしに、東京大学へ行きました。

すると今日が大学の合格発表の日だったらしく、多くの受験生や在校生で賑わっていました。

若いっていいなぁとしんみり思いました。

「しんみり」とは、深く心に感じるようすや寂しい気分を表す言葉です。

セミナーでは、私のこれまでの研究成果を、大学の先生や企業の方々に紹介しました。

多くの方から研究に対する質問や意見を頂くことができ、とても良い機会となりました。

今後も研究を頑張っていきたいという気持ちにより一層なりました。

  This means that they were going to graduate. I don't think that you meant this; you probably meant that they passed entrance exams.

• Since I could get various opinions on questions and opinions to my study, it was a very good nice opportunity for me.

  I had to remove the questions aspect because it doesn't really fit in. They don't work in the same sentence-->You can't say, "Since I could get various opinions and questions on my study..." since you can't get questions on a study, only about a study. You have to choose one or the other or somehow completely rephrase it to include both.
  
  "Nice" isn't used in this context. Most of the time it's used to describe people (e.g. Mary was nice) or sort of one liner to compliment something (e.g. Nice shoes!).

• I will do my study more from now on.
• I will work on do my study more from now on.
