Conflict of interersts in scientific study and bioethics as professionalism

Science in the 21st century does not consider participants' welfare, safety and human rights in clinical studies, but modern science puts economic profits in its priority. This leads to a growing concern about social responsibility and professionalism ethics of companies, sponsors and scientists. Specifically, there is no way to control conflicts of participants' welfare with economic profits, leading to simply relying on individual ethics, social responsibilities and audit. This paper helps relevant agencies and people involved understand conflict of interest. Also this study presents the guidelines as well as independence, autonomy, ethical imagination and phronesis required for scientists.
