Its fully grown body will attain more than 80 em in mantle length or more than 19 kg in weight and its robust body with the enormously developed fins makes it quite distinct from all other teuthoidean cephalopods; these features seem to deserve well of its being called a noticeable creature in the ocean. This cephalopod is found rather frequently and in a moderate quantity in certain districts of Japan and well known to local fishermen by various Japanese names such as "taru-ika" (barrel squid), "hako-ika" (box squid), "sode-ika" (sleeved squid), "kasa­ ika" (umbrella squid), "aka-ika" (red squid), etc. However, it is apparently very scarce in other parts of the world, being recorded outside the Japanese waters so far only from the Mediterranean (TROSCHEL 1857; JATTA 1896; NAEF 1921-28; etc.), the waters around Madeira (REES & MAUL 1956) and the Cape of Good Hope (BARNARD 1934), and almost nothing is known of its life history including migration, behavior, life span, etc.

The aim of this study was to assess the prevalence of ADCA subtypes among patients of Asahikawa Medical Center in Hokkaido. Patients and Methods This study was performed from July 2012 to June 2015. PCR and/or direct sequencing were carried out for 50 participants who were each clinically diagnosed with spinocerebellar ataxia (SCA). Results Among the 50 participants, 25 had familial SCA, and 25 had sporadic SCA. SCA6 was the most common type identified, found in 14 (43.8%) cases among 32 genetically confirmed cases. SCA6 was followed by SCA1, SCA31, and dentatorubral-pallidoluysian atrophy (DRPLA), which each accounted for four (12.5%) of the 32 cases. SCA7 and SCA17 were not detected in this study. Two SCA6 patients were homozygous for a 21-CAG repeat allele, and each presented with early onset, pure cerebellar ataxia. Among the 25 sporadic patients, 11cases (44%) was clarified one case with SCA1, six SCA6, one SCA8, one SCA31, and two DRPLA. Notably, 18 participants could not be classified into an SCA type.

  • Geographical Variation of Dental Measurements in the Jomon Population Abstract Mesiodistal and Buccolingual Crown Measurements W
    J.Anthrop. Soc. Nippon 人 類 誌 97(1):493-512 (1989) Geographical Variation of Dental Measurements in the Jomon Population Hirofumi MATSUMURA Department of Anatomy, Sapporo Medical College Abstract Mesiodistal and buccolingual crown measurements were taken from the permanent tooth remains of the five Middle to Latest Jomon population samples from the Hokkaido, Tohoku, Kanto, Tokai and San'yo districts of Japan. The metrical data were compared with each other through multi- variate statistical methods. The analysis of variance for these crown meas- urements suggested that most of the variables showing significant geogra- phical difference were buccolingual diameters. The distance analysis based on the crown measurements revealed that the Hokkaido Jomon was isolated from the Jomon in Honshu, the main island of Japan. The Honshu Jomon groups were closely related to each other, although the male Tohoku Jomon was slightly closer to the Hokkaido Jomon. The principal factor analysis revealed that the overall dental proportion of the Hokkaido Jomon was dif- ferent from those of the Honshu Jomon groups, and the Tohoku Jomon carried the smallest overall tooth size among the five Jomon population samples com- pared. From the comparisons with recent groups, it was indicated that 1) the diversity in dental morphology between the Hokkaido and Honshu Jomon was smaller than that between the recent Kanto Japanese and the Jomon as a whole ; 2) the dentition of the Jomon population was characterized by relatively small canines, premolars and second molars as compared with the first molars; 3) these dental characteristics could also be seen in the dentition of the Ainu.

  • Blood Types in Japan 1
    Yap. or. Human Genet. 23, 197-209, 1978 THE DISTRIBUTION OF THE RH(D) BLOOD TYPES IN JAPAN 1 Yoshiko FUJITA, Katumi TANAKA,and Masako TANIMURA Department of Human Genetics, Tokyo Medical and Dental University, Tokyo Summary Data on the Rh(D) types of 2,745,618 individuals were collected from prefectural health departments, health centers, and Red Cross blood centers in 35 of 47 prefectures in the whole country. Phenotypic and gene frequencies for each subpopulations were calculated and tabulated. The frequency of Rh(D) negatives in the whole sample is 0.5428~ and the frequency of the Rh(D) negative gene is estimated to be 7.37__+0.03~. An insignificant cline of the frequencies is suggested, i.e. the Rh(D) negative gene is increased from the northeast to the southwest of Japan. INTRODUCTION Frequencies of Rh blood types in different localities in Japan were summarized by Akaishi and Kudo (1975) who compiled available data on 10 prefectures from literature and through their own surveys. A majority of the studied prefectures cluster in the northmost part of the country and, therefore, distribution of the Rh system in the whole of Japan was still uncertain. Recently, examination of the Rh(D) type is extensively carrying out at health centers and blood centers in the whole country. The present authors collected such data and report here the results of the analyses. MATERIALS AND METHODS The data on the numbers of Rh(D) positives and negatives were obtained from health centers, prefectural health departments and Red Cross blood centers by mail.

Furthermore, the preferences and tastes of people from one region to another are rather different. On culture and history, for instance, people in Hokkaido Prefec­ ture, located in far northern Japan, are considerably different from people in Okinawa prefecture, located in far southern Japan. Recently, I unearthed some findings on these problems from analyses based on survey results. Two of them are presented in this paper. One is the differences of consumer attitude among seven districts in Japan. The other is the sensitivity analyses about the respondents' partiality as revealed in answers to questions in the questionnaire. In this paper especially, I would like to emphasize the following results: The questions which cause the respondents' partiality are very important, for they are the bases for differences among the respondents from the various districts. 1. Introduction This paper investigates consumer sensitivity and behavior in seven different districts of Japan. The characteristics of the commercial system; (numbers, types, and sizes of retailers and so on) in those districts could influence their citizens.

Introduction For the research to prevent natural disasters of a district such as landslides and earthquakes, it is necessary to know the geology of this distrct, and it is useful to understand the physical growth or geological history of the district. In this sense the writer intends to try to write the Cainozoic* geological history of the Kinki district in the central part of which our city Kyoto is situated. The Kinki district is located in a western central part of Japan, its area and population being about 33,000 km2 and 15,500,000 respectively. The Kinki district is one of the most densely populated districts of Japan. In this district there are three large cities of over one million inhabitants, i.e. Kyoto (1,220,000), Osaka (3,012,000) and Kobe (1,114,000). The Kinki district occupies the western central part of Honshu, extending between 35°45' N and 33°27' N and between 134°12' E and 136°55' E. The Kinki faces the Japan Sea on the north side and the Pacific on the south. Since the end of the World War II the resarch of the Cainozoic of the Kinki district has been very actively carried out by many geologists, new scientific data having much accumulated.

    Journal of the Faculty of Environmental Science and Technology, Okayama University Vol.18, No.1, pp.1-17, March 2013 The Management of Arable Land in Japan - An Analysis on Transition of Non-cultivated Arable Land - ICHIMINAMI Fumikazu * and DINCSOY Enver Erdinc ** In Japan, the number of full-time farm households had continued to decrease since the latter halfof20th century. The number of part-time households has been also decreasing remarkably in the last twenty years. Cultivated acreage also aligned with these tendencies and it has decreased. As a result, the farmland which is not cultivated increased and it may also grow into a social problem. Therefore, the present condition and future view of Japanese agriculture was elaborately examined in the study by analyzing the transition of non-cultivated arable lands from a historical perspective. Key words: Non-cultivated arable land, Part-time farm households, Non-farm households, Japan 1 INTRODUCTION economic growth on and after the middle of the 20th The two of the main labor force features of century, the non-cultivated lands have been increasing agriculture in Japan are a small size of management and gradually resulting in a significant decrease of the high rate of the elderly employment and part-time farm number of farm households and farmers. households, etc. Another characteristic of agriculture in The subject of non-cultivated arable land is also Japan is the rice, which planted in the paddy field of examined by researchers from different points.

They believed that production of wheat, barley, clover, potatoes, and the like should be encouraged, while rice-plant, soybean, and sweet potato growing should be discouraged.
