In 1993 and 1999, a number of specimens of a poecilid fish collected from a drainage area of the hot spring at Kojyohama, Shiraoi-cho, Shiraoi-gun, southern Hokkaido, Japan was identified as Poecilia sphenops. Identifications were based on males having elongated pelvic-fin tips, in having the dorsal-fin origin posterior to a vertical through the pelvic-fin base, 9-10 dorsal fin rays, no horizontal pigment band and ocellus on the body, no opening of the cephalic sensory canal on the snout, and many tricuspid teeth in the inner row of teeth on the upper jaw. It is believed that small fish were introduced into this area longer than 20 years ago to assist in reducing mosquito populations. At present, high density schools of these small fish were observed swimming throughout the drainages. This report represents the record of habitation and natural breeding of this species in Japan.

1950年代までの予備校は、大学入試に備えた授業と、出版社・学生団体が作成した模擬試験を提供するだけの場であった。しかし、1960年代になると、情報化の重要性に気がつき着手する予備校が出始める。中でも先駆的だったのが名古屋の河合塾であり、高等学校との情報交換を密にし、従来はテリトリーの外であった東京に校舎を設置して、中央の受験情報を独自に収集する体制を取る。それはやがて全国の高等学校・予備校の進路指導に影響を与える「全国型予備校」への第一歩となった。

This research is a historical survey of 16 student organizations, such as "Tokyo University Correspondence Society," that conducted "Academic Competition." These competitions were essentially trial examinations for students of high schools and preparatory schools (private schools for students preparing for university entrance examinations) all over the country. Using university facilities, these student organizations were founded by students to address the problems of student poverty and at the same time to improve the academic achievement of high school students. In this time period, national universities did not properly publicize information regarding campus life. Instead, the universities relied on student organizations to disseminate such information to students and the public. For this reason, they were fostered by university authorities, and their activities were reported in the media. A study of the history of these organizations reveals the following three points: First, there was a dramatic change in the perception of student organizations over the time under consideration. Initially, student organizations were seen as addressing student poverty and improving academic achievement of high school students. Over time, however, these same organizations were thougut to only be taking money from students and worsening "examination hell." As the latter perception became predominant among the public, student organizations were dismantled by 1970. This trend reflects the impact of post-war reconstruction and rapid economic growth that led to a dramatic increase in the number of students seeking a university education. Second, dispite the external shock of entrance exam changes and negative popular preception, these student organizations continued their business as usual. Even as they were seen as money-making ventures, student organizations remained a vital source of information regarding university for entrance examinees and for high schools and preparatory schools. Third, the business model designed by student organizations was unique and innovative, so much so that after their dissolution, their role was inherited by a new entrance exam "industry." After a fouryear absence of practice exams specific to each university, in 1974 Kawaijuku founded "The Tokyo University Open." Thereafter, variations of this model multiplied, and Kawaijuku became nationally recognized and moved its operation to Tokyo in 1977. Kawaijuku's success launched the "preparatory schools war," that lasted until the late 1980s. In a sense, student organizations were the precursors of the "preparatory schools war."

The purpose of this paper is to clarify the ownership patterns and management characteristics of the Indian zaibatsu from the standpoint of the types of the zaibatsu families; a) the joint family type (the Walchands, the Singhanias, the Bajajs), b) the split type (the Goenkas, the Birlas), and c) other types (small family type; the Mahindras, alien type; the Tatas).Some of the concluding observations are as follows : 1) On the whole, inter-corporate investment and multiple directorship as the instrument of control play the significant role in all the zaibatsu, though the pattern varies widely among the groups. Generally it can be said that the larger the joint family is, the stronger tends to be the zaibatsu families' holds over both ownership and management. 2) In the case of the split type, both ownership and management are retained independently by each sub-group of the zaibatsu family. To be noted is the case of the ownership of the R.P. Goenkas, one of the three subgroups of the Goenkas, where a number of investment companies that are subsidiaries of the four main companies of the group play the decisive role in the shareholdings of the group companies. 3) In the Mahindras, the small family type, the main family members hold the ultimate decision making power of the nuclear (holding) company, thereby controling quite a few of their group companies.
