The aim of our project is to provide opportunities of smoking cessation to smokers by health guidance in the community health service, industrial health care, and school health care etc. Finally, we hope to increase the number of smokers who perform the smoking cessation and successfully quit smoking. In order to achieve this objective, we will develop e-learning system, science-based information booklet for staff in the field of health/medical care and social services to know how to support smoking cessation for smokers. In particular, we can offer learning opportunities for many people using e-learning system. However, it is difficult to build an instructor network with only e-learning system, we will also have training session in the conventional classroom structure.
