Young's modulus of a substrate is an important parameter for measuring thin film magnetostriction. We report a simple method of measuring it using a sensitive capacitance bridge. The thin plate sample parallely cantileverd to a metal plate holder below forms a capacitive unit. The bending force due to gravity is mg cos θas sample is rotated θfrom the horizontal. The capacitance change due to this bending is detected by a transformer-ratio-arm bridge. Young's modulus is obtained with theoretical analysis by the capacitance change. This method can be used for thin conducting plate also. Several results almost agreed with published data.

The purpose of this study is to find out the process of change in the regulations for judgements in Judo game according to the division of the era. The study is to deal about how the process of change in the regulations for judgements conducts. Also, it is to find out the meaning abut the regulations for judgements of Judo Games. According to the division of the era, the first period was when Kanojigoro of Japan created the method that judges Judo free game in the operation of Kodokan techniques before consulting the regulations of authorized wrestling in 1930. The second period was when the regulations of Judo game were made with the help of the regulations of wrestling in 1930 and it was from the foundation of the International Judo Association in 1951 to before the choice with regular game in Olympic Games. The third period was when the regulations that judges Judo were reinforced since the choice in Olympic games. The regulations that judges Judo were settled and the time of the Judo game, the uniform, number, role of referees, the items of prohibition and the guidelines of scores were fixed in details. As mentioned above, the great change in regulations of Judo Games gave rise to the change of the new codified regulations in Kodokan in 1930's. In addition, before the foundation of the International Judo Association, the regulations made by the various kinds of organizations that held Judo game included the characteristic contents of them and since 1930's each organization such as Japanese police agency, Mudeokhoi and Kodokan made the similar game rules with one another. After the foundation of the International Judo Association, the regulations for judgements of Judo game were changed as the starting point many types of Olympics. Since 1996, Judo has established as a international game and the regulations for judgements of Judo game have reflected the impartiality of rules by being aware of audiences and TV hook up. Above all, since 1990's it has characterized by the enforcement of regulations for stronger judgements rather than the items of penalty regulations. As a result, the regulations for judgments of Judo game include impartiality of game operation, safety of players and absoluteness of referees' judgments. First, impartiality of game operation is that the practical regulations are the game rules for judgments in Judo game. Referees must judge in the game rules and prohibited techniques must be punished definitely and impartially right away. At this time, The translation of the regulations must not judge individually, and must be objective as soon as possible. Most of the regulations of the judgments consist of three referees considering the difficult tasks of referees. The threereferees consist of a referee and two judges. Two judges are placed to support a referee as they judge independently standing abetter location. The referee must accept the judgments of the judges without question and the final judgement made by three referees must be fair and accurate. Second, safety of players is close connected with Judo techniques. Also, we can know how safety of playershas developed by the change of prohibited techniques. Before 1990's players had to punish by using irregular techniques and uselimited techniques to protect the injury of the players. These change in the regulations for judgments include a great meaning in Judo game. Third, absoluteness of referees' judgments made for the right judgment and the consideration of audience and after 1990's the regulations for judgments included the details of penalty items. These seems to consider Judo modern sportscontrolled by audiences than self-training. Thus, the method for judgments in Judo game is suitable for the events and must keep the objective rules. These are satisfied with the esthetic demands of the audiences through the characteristics and the distinctive, lively shape of Judo. Therefore, in the future the facilities and regulations for judgements in Judo have to be suitable for thetechnical aspect. In terms of the sports Judo is required to various kinds of the development of regulations for judgements because of the demands of the spectators.

Background: Pulmonary tuberculosis is a great public health problem in Korea. Early detection of Mycobacterium tuberculosis (M. tuberculosis) in clinical samples becomes more and more important in the control of tuberculosis. Recently, molecular methods have been applied to early detection of M. tuberculosis. Methods: To elucidate the effectiveness of nested polymerase chain reaction (PCR) in early diagnosis of pulmonary tuberculosis, we peformed Acid-fast bacilli (AFB) stain, AFB culture, and nested PCR on 84 sputa. Results: 8 (9.5%) specimens were positive by AFB stain, 17 (20.2%) by AFB culture, and 15 (17.9%) by nested PCR. Using AFB culture as standard method, the sensitivity of AFB stain and nested PCR was 47.1% and 82.4%, respectively. The specificity of AFB stain and nested PCR was 100% and 98.5%, respectively. Conclusions: Nested PCR was more sensitive than AFB stain and had shorter processing time(24-48hrs) than AFB culture. So it may be effective to use nested PCR in order to detect M. tuberculosis when AFB smear Is negative.
