Background
: Since the Independence in 1945, the Republic of Korea(ROK) has maintained fundamentally the liberal health care system by the influence of U.S.A. Therefore, as in the case of U.S.A., the primary health care system of ROK has fallen in the chaos. Recently, the new government of ROK seems to retry the introduction of 'Family Doctor Registration System(FDRS)' in spite of the 1996's failure. In order to conduct FDRS efficiently, there should be a thorough investigation on the opinions of doctors and people in the community. This study was conducted with a view to collecting necessary information regarding the implementation of FDRS.

Methods : By mailing, the self-administered questionnaires were collected twice during March 18 to May 12 in 1998. The questionnaire had been prepared trough several discussions, pretest, and final correction by five family physicians and two health care policy professors. The subjects consisted of 2,093 family physicians.

Results : Though the overall response rate was only 28.2%(591) subjects, age distribution for the study subjects was similar to that of average family physicians. The subjects consisted of 451 males and 138 females. The number of those whose age was less than 40 was 49.9%(195). 'The group that agrees with the introduction of FDRS' was 58.5% of all respondents; 'the group that objects' 14.4%; and 'the group undetermined' 24.7%. The 73.6% of all respondents had negative opinion on increased administrative work. Only 21.3% expected their net income to increase. On multiple logistic regression analysis, relatively large city rather than metropolitan Seoul, the smaller number of visiting patients a month, regular resident training experience, and male sex resulted in having a significant positive relationship with the introduction of FDRS. Further analyses are called for to identify differences of opinions between family physicians and single specialty medical practitioners

Conclusion : The results of this survey should be reflected into the health care policy when retrying to implement FDRS in Korea.

Background
: Osteoporosis is one of the characteristic adult diseases and important health problem. It brings to high prevalence, easy fracture, many complications, and lowers geriat-ric quality of life. With concern about osteoporosis as a primary care physician, we would like to know the relations between risk factors and BMD.

Methods : Among the patients who have taken the Bone-mineralodensitometry(BMD) ex-amination, from January. 4, 1994, to July. 31, 1995, at Sung Nam Central Hospital, we sele-cted 112. Data was gathered from the BMD examination and questionnaire. These data were analysed using SPSS/PC correlation and stepwise multiple regression statistic program.

Results : The study subjects were composed of 112 patients (female:51, male:61). By osteoporosis definition, the 2.5 S.D. below the peak bone mass is 51(45.5%), the normal group is 61(54.5%). In the stepwise multiple regression analysis, the most important risk factors are age and weight in female, exercise and weight in male.

Conclusion : In the prevention and early diagnosis and treatment of osteoporosis, the physician should consider the risk factors. Due to noticeable frequency of male osteoporosis, more studies are needed.
