what does the word yaavetz mean, as in Mishnat Yaavetz?

Dear Rabbi, I work in a Chassidish establishment that has a number of public bathrooms. I am concerned regarding some issues related to personal hygiene. My main concern is that there is no handwashing (with soap) taking place inside or outside of the bathroom. As a matter of fact, there is not even a sink in the bathroom with which to wash ones hands, only one OUTSIDE of the bathroom. Now when the folks come out, they wash their hands with a washing cup but no soap. They then move about the facility and continue to spread germs all over the place. Can you please explain to me how a group of people who is so makpid in every area of life can be so lackadaisical in this very important area of personal hygiene? Thank you, Concerned.

Dear Rabbi, I want to know the meaning of Anosh Un Nahoor. Is it like Light of Human Being? If not what it will be the in Hebrew? And If Nohshon Un Akhim is the Hebrew of Clever among the Brothers? If not what is it? Thank You. Shamim
