Few studies have examined medical students' perceptions of community medicine and specialty choice through comparison between students of quotas related to community medicine and regular admission. We conducted a questionnaire survey on students' desire for future work places, types of health facility/hospital, medical specialization, and community medicine involving year 1 to year 5 students in Gifu University School of Medicine (n=335, selective admission: regular admission=81:254) . This study demonstrated that the selected students for community medicine (years 1 to 5) preferred to work at a core/small-sized hospital in a rural area and tended to choose the specialties that were characterized by primary care, such as pediatrics. Moreover, they had positive perceptions of community medicine. Further follow-up study needs to be undertaken in order to explore how students are actually engaging in community medicine after graduation.

Aim : Since it was reported that acupuncture at Danchu (CV17) was critical when the needle penetrated through the congenital sternal foramen, we decided to study the incidence of the congenital sternal foramen, as well as the distance between the body surface and the back side of the sternum at Danchu, in order to know the safe depth of acupuncture penetration.
Method : 1) We selected 51 cadavers to examine the incidence of congenital sternal foramen and, if any, to study its structure. We also selected 21 cadavers to measure the cadaveric thickness of the sternum. 2) We selected 31 people to measure the incidence of the congenital sternal foramen and the distancebetween the body surface and the back side of the sternum at the point of Danchu.
Results : 1) We found one out of 51 cadavers which had congenital sternal foramen. The location of the foramen was at the height of the fourth intercostal space. It was round-shaped, 9mm in diameter, and filled with hard connective tissue. The thickness of the sternum ranged from 9 to 15mm with an average of 11.5 ± 2mm. 2) There was no one who had the congenital sternal foramen among the 32 people. The distance between the body surface and the back side of the sternum ranged from 11 to 31mm with an average of 18.8 ± 5mm.
Conclusion; 1) The incidence of the congenital sternal foramen in this study was one in 51 cadavers and zero in 32 people. 2) We concluded that acupuncture at Danchu within a depth of 10mm is sufficiently, even if congenital sternal foramen exists.
