Background
: In recent years, the interest of people in health promotion and disease prevention is increased by virtue of economic growth. And the effort of promoting health, preventing and treating disease through food is added up too. In order to investigate the recognition about food which affects health and disease, we carried out this study.

Methods : We selected randomly the patients (group 1) who visited family medicine clinic of SNUH during period from August to September 1993 and one high school students family members(group 2) who are above 20 years old, for 4 paged questionnaire.

Results : Group 1 consists of 292 persons(male 36.0%, chronic patients 50%) and group 2 consists of 172 persons(male 35.5%, chronic patients 16.5%). Both groups answer that the food is the most important factor that affects health and disease. And they think that the best food for health is vegetable and the worst food is irritative one. They answer that the recommendation from the doctor is the most important factor that affects the diet therapy in chronic patients.

Conclusion : People regard food as the most important tool to promote health. The response on the importance of the food as the way of preventing and treating disease in positive in general. And it is proved that doctors play the most significant role of the diet therapy education for the chronic patients.

Background
: Computer use in medicine is also incresing now in primary health care. Untill now, there has been no report on the clinical use of computer in family pracice in Korea.

Methods : Among 525 members of Korean Academy of Family Physicians woh are in primary practice in Seoul, 297 physicaian's office telephone numbers are on phone-directory. In August 1993, four-page questionnaires were sent to 297 physicians. To get higher response rate was 52%. To compensate low response rate, phone interview of 38 physician was done by random sampling of nonresponders.

Results : 79% of responders currently use computer in clinic, while 32% use computer personally. There were no differences between responders and nonresponders in sex, rate of computer use, but mean age of responders is lower than that of nonresponders(50.8±13.5 vs. 57.1±10.9). Among clinical usages of computer, billing is by far common(100%). Medical record retrieval systems anre used by 26.4%, Drug management by 14.6% of physicians with computers in their offices. Only one physician used complete electronic medical record.

Conclusion : Majority of family physicians in primary health care use computer in clinic. But the use is confined to a few areas. Among the variabels, age and personal computer use seem to be related to the number of arease used. Major obstacles to the medical computing are 'not acquainted with computer use', 'lack of standardization of programs'. So there are urgent needs for education of computing and standardization of programs.
