The Snowball Effect: From a Study to a Big Investigation   Eun Hui bae, M.D.,Ph.D.   Departments of Internal Medicine, Chonnam National University Medical School, Gwangju, Korea   Doing well in research and publishing good paper in high impact factor journals can be every doctor's dream. But why do we spend time researching and publishing papers? For long-lasting research, it is necessary to clarify the purpose first. Today, in this hour, I would like to mainly talk about the characteristics and types of the research and papers, and the types and characteristics of research funds. Finally, I will summarize the papers I published last year, and introduce the research funds I applied for last year. I think the best way to do long-lasting research is to have a fun with the many people you work with.   Keywords: Kidney, Research, Fund, Investigation, paper, journal. Co-worker.
