We present the in-flight performance of the X-ray telescopes (XRTs) onboard Suzaku. The imaging capability is significantly improved over the ASCA XRT, which had half-power diameters of 3'.6, to 1'.8-2'.3 for all four XRT-I modules. Contemporaneous fits of a power law to all the XIS spectra of the Crab Nebula taken at the two standard observing positions (XIS/HXD-default positions) gives a flux consistent with that obtained by Toor & Seward (1974) to within〜2%. The pre-collimator on the top of each XRT module successfully reduces the intensity of the stray light from the 20' and 50'-off directions down to the level of pre-flight expectations. We also present the thermal wobbling of the satellite. The wobbling causes the alignment error between the XRT-XIS system and the attitude and orbit control system. The wobbling of the alignment is as large as〜1arcmin. In the currently processed data, the absolute coordinate also has systematic uncertainty of up to〜1arcmin.

After World War II, the idea of education and teaching profession changed completely in Japan. The old concepts were replaced by the new ones, chiefly of professionalism and unionism. The purpose of this study is to examine the attitudes toward 'professionalism' which the present-day teachers assumes. Our questionnaires were sent to 1,085 teachers of senior and junior schools and primary schools in three prefectures. Our aim of this questioning was to explore the three aspects which we thought to be the most important as the elements of the profession. They are (I) autonomy in teachers' instructional activities, (II) autonomy of the professional organization, and (III) professional ethics and belief. We received 736 auswers from the teachers. And as a whole, (I) showed the most remarkable result and (II) the least. Teachers are discreet enough to think it important to select textbooks freely and adopt his own teaching methods, but they considerably allow for the role of their principals. There are few who think that the professional organization should participate in the decison of the criteria of the teacher's certificate. Most teachers assume that they are performing an essential function of the society, but not many regard the belief in public service as of importance. There is a close relation between attributes of teachers and (I) and (II). It is the teachers lower in rank-members of Japan Teachers Union (JTU) and of its friendly organizations, graduates of national or municipal universities or collges, and teachers from twenty to thirty-nine years of age-who constantly demand their professional autonomy; whereas it is the head teachers and those next to them in rank-members of anti-JTU associations, graduates of normal schools, and teachers over fifty years of age-who are committed to (III). On the whole, their professional consciousness is inferior to that of the former. And we proceed to examine the relation between the conception of profession and morality, for it functions as a standard of demmand in teaching. These analysis give the result that the morality of the teacher more attached to professionalism is lower than that of those less attached.
