The oxidative polymerization of aryl sulfoxides provides a novel polysulfo-nium compound, poly(methylsulfonio-1,4-phenylenethio-1,4-phenylene cation) in quantita-tive yield. The polymerization proceeds efficiently in an acidic solution under atmosphericconditions. Oxygen, chemical and electrochemical oxidations are available. Vanadyl acety-lacetonate and cerium ammonium nitrate act as an effective catalyst for the oxygen ox-idative polymerization. The polymerization mechanism involves multielectron oxidation ofthe sulfides followed by successive electrophilic substitution. The resulting polyarylenesul-fonium cations are useful as a soluble precursor for the synthesis of high molecular weight(M_w>10~5) poly(thio arylne)s.

day work and shift work) and cigarette smoking in Japanese workers. We used data of 3,238 men (39.3 ± 10.5 years) and 5,111 women (37.1 ± 10.9 years), aged 20 - 59 years, by cross-sectional clinical investigation study. Work style i.e. day work and shift work, cigarette smoking, status of stress and stress coping were obtained by questionnaires by well-trained medical staff. A total of 227 men (7.0%) and 339 women (6.6%) were shift workers, and 1346 men (41.6%) and 649 women (12.7%) were current smokers. Work style was significantly linked to cigarette smoking, stress and stress coping after adjusting for age in women. In addition, the level of stress coping in subjects with cigarette smoking was significantly lower than that in subjects without cigarette smoking even after adjusting for age in women. However, these associations were not noted in men. Work style was critically associated with cigarette smoking in Japanese female workers.

The effect of cigarette smoking on flexibility in Japanese

作者： Kanae Oda Nobuyuki miyatake Noriko Sakano Takeshi Saito Akihiko Katayama kenji Nishii Takeyuki Numata Department of Hygiene Faculty of Medicine Kagawa University Kagawa Japan Okayama Health Foundation Hospital Okayama Japan Okayama Southern Institute of Health Okayama Health Foundation Okayama Japan

To investigate the link between cigarette smoking and flexibility in the Japanese population, we used data of 4234 men and 9169 women, aged 20-79 years, in this cross-sectional investigation study. Flexibility such as sit and reach were measured. In addition, habits of cigarette smoking and exercise were obtained by well-trained medical staff. The effect of cigarette smoking on flexibility was evaluated. A total of 1613 men (38.1%) and 995 women (10.9%) were having habits of cigarette smoking. Flexibility in men was decreased with aging and that in women increased with aging under 60’s. Flexibility in subjects with cigarette smoking was significantly lower than that in subjects without cigarette smoking even after adjusting for age and exercise habits in both sexes. Cigarette smoking might be modifiable factor of flexibility in the Japanese.
