A molar with negligible attrition was fixed in the tricuspal position where the position of the protoconid, metaconid and hypoconid were in a horizontal plane. A moire photograph in the pitch of 0.2 mm was thus obtained and examined. The frequency of occurrence of a tubercle was counted in three grades according to its contour patterns. The traits and their sex-pooled frequencies were as follows (n=45): (1) Mesial Accessory Tubercle, 17.8%;(2) Metaconid Mesial Accessory Tubercle, 8.9%;(3) Metaconid Distal Accessory Tubercle, 57.8%; (4) Distal Trigonid Crest, 17.8%;(5) Deflecting Wrinkle, 46.7%;(6) Sixth Cusp, 35.5%; (7) Entoconid Mesial Accessory Ridge, 0%; (8) Protostylid, 73.3%. The incidences of the traits were compared with those in the permanent first molars previously studied. The traits nos. 2, 3, 4 and 8 were significantly more frequent in the deciduous molars than in the permanent ones when tested by χ2 test. On the other hand, the frequencies of trait nos. 1, 5, 6 and 7 were not significantly different between both molars. Three of four traits showing significant difference located around the metaconid, which indicated the high morphological variability of the metaconid in the deciduous lower second molar.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"100 1","pages":"43-51"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67030515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the following were recognized as the characteristics of fast speed walking in old men; (1) the walking speed, step length, and brake impulse as well as acceleration impulse began to decrease pronouncedly from the age group in their 60s, (2) the walking of subjects in their 60s and 70s were hastened from the ordinary speed level with almost the same ratios as in the younger subjects, (3) increase of the step length during the fast speed walking, against those during the ordinary speed walking, was smaller in subjects in their 70s than in the younger, (4) increase of the brake impulse during the fast speed walking, against those during the ordinary speed walking, began to decrease from the age-group in their 60s, while (5) that of the acceleration impulse remained unchanged with age. The principal component analysis revealed that (6) the contents of the fast speed walking are almost identical in ages between 20s and 50s, suggesting that they begin to change at one's 60s.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"43 1","pages":"499-509"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1537/ASE1911.100.499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67030539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These data were analyzed in order to evaluate the magnitude of inter-population differences and the influence of secular change on the interpopulation differences. Cranial measurements taken for four populations from the late Edo period were used to estimate the inter-population differences that can be caused by systematic inter-observer measurement errors and by the bias in the sampling. The distance measures based on the measurement items with small intraand inter-observer measurement errors indicate that the inter-population differences in modern Japanese crania are much greater than the differences caused by the measurement error. However, the differences caused by sample bias are as large as some of the inter-population differences. The results of cluster analyses indicate that the influence of secular change can not be ignored. According to the results of discriminant analysis, the key characteristic in determining inter-population difference is maximum cranial breadth. Since secular change is observed in seven out of 13 measurement items with significant inter-population differences, a considerable part of so-called geographic differences among modern Japanese crania is likely to be due to the secular change that took place during the 100 year period required to collect the materials.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"92 1","pages":"405-416"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67030504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
