A comparison of simple true-false questions (STFQ) and multiple choice questions (MCQ) plus multiple true-false questions (MTFQ), in the same contents was done at the graduation examination of our department (on 1987. 12. 7.). The mean score of STFQ was 83.7 mark and its standerd deviation was 4.6 mark, and in MCQ plus MTFQ the value was 77.1, 9.0, respectively. At the same student, the mark of STFQ and MCQ plus MTFQ was correlated. We concluded that the handling of the question with high percent of correct answer was induction of the individual total item check method. Then, evaluation got more validity.

Generally, sport players of boxing or football who contact roughly with other players use mouth guard during match or game to prevent the breaking of jow boneor bursting of soft oral cavity. Moreover, mouth-guard are used for the purpose to lighter the load to root of teeth and to improve the skill and power of sport's player.
The purpose of this study was to examine the charactaristic of unfitted by H shape-mouth guard compared to U shape mouth guard.
The following results were obtained.
1. The H shape-mouth guard of this study could reduce the impact to 1/7 level.
2. A relative decrease in ventilation level was shown when H shape mouth guard fitted.
3. With reference to respiratory function, reduction of the amount of oxygen up-take was not observed at heart rate lower than 170 beats/min, and in this case a player feells subjective symptom of stiffing.

We have developed a mouth guard which has revolutionized the shape and material of the conventional mouth piece. The H shape mouth guard has the unique shape like that of an H. Even with the new shape of the mouth piece it does not hinder the performance of the wearer. The following are the fundamental data collected by our group. In this study we examined its influences on leg power, the carry (the distance a golf ball is hit) and the motion of the club head during a tee off.
The results are as follows:
1) By wearing or setting the mouth guard, the variation of leg power, measured with a Sybex II, showed an increase at selected angular verocity. The rate of increase averaged aproximately 15%.
2) The amount of work in anaerodush, an intensive, but short exercise, increased significantly by 1.25 seconds.
3) As for golf, all four of the test subjects joint performance increased their carries by 5.2 to 11.6 yards, using a 1st wood.
4) Also the fluctuation of the head of the club decreased from 7.3 cm to 3.6 cm on average.
Our group have found that the new H shaped mouth guard can absorb shock as well as not hinder the performance of the individual who is wearing it. Thus, the H shape mouth guard can be worn during sports to enhance the participant's performance.

Background : Since 2002, Keio University Hospital's Kampo Clinic has promoted itself actively through the media, public presentations, faculty outreach and an internet home page. However, the relative value of these promotions is unknown. Additionally, the range and prevalence of presenting concerns, and the ages and the gender ratio of the patients served at Keio is unknown.Objective and Methods : To better understand and better serve the patients, the medical charts of every new patient who presented to Keio University Hospital's Kampo Clinic from November 2004 to November 2005 (n=791) were retrospectively analyzed for 1) referral source, 2) age, 3) gender, and, 4) disease category.Results : The internet webpage was by far the best source of new patient referrals. The out-of-hospital referral rate to the clinic was remarkably low. Women exceeded men by a 3 : 1 ratio. Most women were in their thirties but male patients were fairly evenly distributed across the age spectrum. Patients under 16 and over 70 were gender-balanced. The vast majority of patients presented with general medicine/pediatric, dermatological or gynecological problems.Conclusion : A patient-oriented internet home page provides a good source of new patient referrals. Given the low rate of referrals from outside hospitals and physicians, additional outreach directed at internal medicine, dermatology or obstetrics/gynecology physicians appears warranted.
