1) Needs for PBM education were pointed out with relation to clinical research, medical care and health administration
.2) The meaning of population and PBM was discussed in historical context of health supervision and medical care.
3) Discussions were made on problems of undergraduate and postgraduate education in social medicine, importance of PBM education in the community, co-operative specialized training in relevant institutions and the role of thespecialists.

Although the Ministery of Health and Welfare, Japan, has an intention to revamp the medical care delivery system, the majority of physicians are currently practicing in the context of some sort of public medical insurance system. Therefore, it is madatory that medical students and young physicians understand public medical insurance system and economical issues to practice medicine in a cost-effective way. We propose here neurosurgical cases used for that purpose employing problem-based learning method in tutorial system.

The aim of this study is to clarify the present situation of activities of continuing medical education (CME) for the primary care physicians to whom the leading hospitals, such as universities and clinical trainee hospitals perform CME in their regions. A questionaire was designed for main 4 parts, as following: 1) On the purpose of CME for the physicians. 2) On the organization (office) managing CME in the hospitals. 3) On the strategies of CME. 4) On the evaluation of CME. Answers to a questionaire were replied from 234 institutions (58.1%). Analyzing the results, we recognized that the leading hospitals actively carried out CME for the primary care physicians in the community. Furthermore, conversion to experiential learning from passive learning and establishment of evaluation methods should be promoted in CME.

Because new media have come onstage in the information technology period, also self-learning methods have been diversified. Recently, small group discussion such as clinical conference using the mailing list is lively performed among the primary care physicians, and it is considered to be useful for continuing medical education. To promote the mailing list for continuing medical education, we present as follows; 1) present situation: to show a good example of TFC-ML (total family care-mailing list), 2) usefulness: to know new medical knowledge, new medical information and literatures etc., to discuss clinical cases. 3) issues: a role of moderator, excess of information, correspondence with slander, 4) future: to reevaluate usefulness for continuing medical education. We would like to expect effectiveness of mailing list for continuing medical education.

OBJECTIVESMetabolic rate is affected not solely by diet but also by environmental characteristics such as climate and seasonal changes in day length. In the present study, we conducted a controlled study in which we observed metabolic response to short-term energy restriction (ER).

MATERIALS AND METHODSThirty-two subjects were divided randomly into a slight ER group and a moderate ER group. The energy intake per day for slight ER vs moderate ER was 1462 kcal vs 1114 kcal. During the 4-day study periods, the same daily timetable, which consists of nutrition, exercise, sleeping and others, was imposed on both groups. The same environment was also provided to both groups.

RESULTSAfter the 4-day ER, significant decreases in body weight and basal metabolic rate (BMR) were shown in both groups. The decrease in body weight was 2% of the baseline level in both groups, and the decreases in the BMR were 6% of baseline levels in the slight ER group and 13% in the moderate ER group. The decrease in BMR in the moderate ER group was significantly larger than that in the slight ER group.

CONCLUSIONSIn a controlled study of short-term ER, we observed a significant decrease in BMR. There was a positive association between the degree of ER and the reduction in BMR. Reductions in BMR were greater than those in body weight. It, thus, appears that the minimization of weight loss is due to dramatic decreases in BMR. This suggests the existence of metabolic resistance against ER.

We used questionnaires to study the present status of undergraduate clinical training at medical schools in Japan in February 1996. Completed questionnaires were returned by 81%(65) of 80 medical schools and approximately 54%(1, 328 clinical departments) of the schools. The results were as follows. Courses for early clinical exposure in the 1st or 2nd year were provided at 83% of the 65 schools; clinical clerkships in the 5th and 6th years were provided at 28%. Specific behavioral objectives for clinical training were clearly shown to students and teaching staff at 75% of schools. Clinical procedures that medical students were permitted to perform were listed and announced to students and teaching staffs at 66% of schools. Patients were informed and gave consent for clinical training of students at 77% of schools. Essential knowledge and skills of students were assessed before the start of clinical training at 40% of schools, and summative assessment was made at the end of the training at 72%. Training of clinical teaching staff for faculty development was conducted at 51% of schools. Eightynine percent of schools reported a shortage of clinical teaching staff. Similar results were obtained in the survey of clinical departments of university hospitals: most departments complained of a shortage of teaching staff, of students not being active, and of students not being competent to enter clinical training courses. To improve clinical training, the introduction of clinical clerkships and cooperation with community facilities outside universities were the main issues.
