By the code of ethics concerning ethnographical research, I am not in the measure to show you the people who are the most important for my work – my key informants and the participants from my fields. This is why on following pictures you will not find the faces of people, except the sociologist. I am sorry for that, because after so many years some of them become my close friends. Guys! Professional secret! I am sorry! But you are always in my heart! Thank you for your time, patience and understanding! Than you for supporting me so long time! And thank you for explaining me your work, sharing yours worries and dreams! Hope my work will be useful for you too. This is also a reason why I create this cite. This is Yours place, and the place of all researchers working in a lab.
