The purposes of this study were to analyze the process of ego identity reconfirmation in the athletic retirement, to identify the roles of anticipatory socialization and time perspective in the process, and to examine the effect of retiring experience for the middle-age crisis. Subjects were two former Olympians who had experienced the middle-age crisis. Several semi-structured interviews were done to each of them. The following 3 points were suggested. 1) Four stages were found in the process of ego identity reconfirmation in the athletic retirement; I: the onset of taking account of his/her athletic retirement, II: reconsideration of his/her life as an athlete and choosing his/her course toward athletic retirement, III: transition from athletic activity, : active commitment into his/her workplace. 2) Anticipatory socialization encouraged to transfer to the next stage of life, and time perspective was a major indicator for the degree of resolution of the developmental tasks in ego identity reconfirmation. 3) Unresolved tasks with ego identity reconfirmation on the athletic retirement were brought up again in middle age

o clarify the levels of organochlorine compounds (OCs) and the metabolism of OCs in the body of Steller sea lion Eumetopias jubatus migrating along the coast of Hokkaido, OCs in the sea lion's blubbers for each age, sex and reproductive status were determined by gas chromatography linked to ion trap mass spectrometer. In sea lions, the compounds accumulated in the highest concentrations are DDT and its metabolites (DDTs) suggesting these animals are still exposed to DDTs from the surrounding land. The levels of DDTs and polychlorinated biphenyls (PCBs) in sea lions may cause small effects such as the induction of drug metabolizing enzymes. The concentrations of DDTs, PCBs, hexachlorocyclohexanes and chlordanes in the old female sea lions were lower than those in the males and young females. This is most likely due to the loss of these compounds during nursing. In addition, the concentrations of each compound differed in the degree of difference between the young and the old females. This result may reflect ecological and physiological difference between the young and the old females. The proportions of tetrachlorinated biphenyl concentrations with vicinal hydrogen atoms in para- and meta- positions to total tetrachlorinated biphenyl concentrations were found to be higher in older animals implying low “phenobarbital inducible type” enzyme activity.
