Schellbach-style Formulae for the Derousseau-Pampuch Generalizations of the Malfatti Circles

It is known that there exist 32 triplets of circles such that each circle is tangent to the other two circles and to two of the sides of the triangle or their extensions. We provide formulae to obtain the radii of the circles for each of the 32 triplets from the side lengths of the reference triangle by means of trigonometric or hyperbolic functions.Comment: 48 pages, 34 figures.

Changing Labor Market in Japan since the end of World War II

The purpose of this paper is to clarify changes in the spatial structure of the labor market in Japan since the end of World War II. The author therefore discusses the following points: 1) the changes in the labor market in Japan, 2) the spatial structure of labor market in Japan, The results are summarized as follows. In labor market studies, it has been recognized that the labor market is not a homogeneous structure but a segmented one, because there are some differences among the labor force in terms of wage disparity, labor movement, etc. In recent years, much research indicates that the boundaries of the segmentation of the labor market are fluid and indistinct. However, Labor economics are not very interested in issues related to spatial relations. In Geography labor market studies have changed in scope since the 1960s. Since the 1960s a number of manufacturing plants for, notably, textiles and electronics have been located in the rural areas to take advantage of cheap labor. These factories have influenced the local labor market and the occupational structure in this area, as would be expected. Following the collapse of the ""bubble economy"", young people entering the labor market as non-regular workers have increased in metropolitan areas. In the 1990s, production from manufacturing tended to decline in Japan. As a result of this decline, both the proportion of part-time workers and the unemployment rate increased. On the other hand, we can see some growth in the welfare service sector for the elderly in the rural areas in the 1990s. However, this sector can be characterized by such working conditions as low wages and instability of status. In order to develop research methods in this field further, we have some issues to resolve: 1) the character of spatial structure of the labor market in Japan since the 1990s, and 2) the mechanism of the regional differences on the labor market condition

Changing Employment Structure in Middle-South Kyushu : the Analysis in the 1990's by Population Census and Establishment Census

This paper analyses changes m the employment structure in Middle South Kyushu after 1970, especially in the 1990's. For this purposes, the author uses principal component analysis and cluster analysis. The districts for these analyses are 234 administrative units (shi, cho, son) in Kumamoto, Miyazaki and Kagoshima prefectures. The results are summarized as follows. The employed persons in construction industry have increased in the 1970's and the period of 1991-1996, and decreased in the period of 1996-1999. These changes reflect the movement of the Japanese public investment policy after 1970. The employed persons in manufacturing industry have decreased in 1991-1999 year period. The decrease of the employed persons was remarkable with manufacture of textiles and manufacture of apparel and other finished textile products. The employed persons in these two types of manufacturing sectors decreased markedly in the districts that showed more than 10 percent in the percentage of these manufacturing sectors in 1991. In 1970-1990 year period the employed persons in service industries have increased remarkably in the districts which have a large growth in population. In the 1990's, however, the employed persons in service industries showed a tendency of increasing even in the districts that have a decrease in population. Moreover, the employed persons have increased remarkably in the medical service and the welfare service sector for the elderly in the 1990's

本研究では，愛知県を事例として大都市圏における介護サービス業の労働市場の特徴を統計データの分析をもとに検討した．分析の結果，介護保険制度の導入以降，介護サービス事業所で従事する労働者が増加するのみならず，居住密度の高い名古屋市都心部では特に営利企業の訪問介護事業所の立地が著しく，訪問介護労働者の割合が増大していることが確認された．さらに，介護サービス業では求人に対する充足率が低く，必要とする労働力を確保できていないこと，また充足率が名古屋市およびその周辺地域で低く，名古屋市から離れた愛知県東部で高いという地域的な差異が明らかになった

本研究では， 名古屋市での実態調査をもとに， 大都市圏の介護サービス業における女性従業者の増加要因を， 介護サービス産業側と従業者側の両面から検討した． 分析の結果， 家事の合間に身近な職場で家計補助として働きたい， あるいは資格や経験を生かしたいと考える女性の存在と， 駐車場や託児施設の確保など事業所による雇用面での工夫が合致して， 女性従業者が増加したことが明らかになった

本研究では， 人材サービス業にとって主要な労働力調達地域である国内周辺地域を対象に， 人材サービス業で就業する労働者の就業状況を分析し， この産業への労働力供給の要因を考察する． このため， 鹿児島市の 17 の人材サービス事業所で得た聞き取り調査の結果， および就職説明会参加者 68 人に対する聞き取り調査の結果を用いて分析を行った．労働者データの分析の結果， 人材サービス業での就職を希望する最大の理由は 「賃金支給額の多さ」 であり， 賃金の地域差がこの地域からの労働力供給の要因になっている． ただし， 年齢で動機や就業行動が異なると考えられるため， 回答者を 35 歳未満と 35 歳以上に分類して分析すると， 35 歳未満の若年者とりわけ単身者では， 条件の良い職業を求めて短期間で転職を繰り返している点が特徴的である． これに対して 35 歳以上の中高年では， 製造業務の経験を生かせる職業を求めて人材サービス業に応募している点が特徴的である． 後者には直接雇用での製造業務経験者が 57％と多く， 近年減少した直接雇用求人の代わりに人材サービス業を選択している

Effective Dini's Theorem on Effectively Compact Metric Spaces

AbstractWe show that if a computable sequence of real-valued functions on an effectively compact metric space converges pointwise monotonically to a computable function, then the sequence converges effectively uniformly to the function. This is an effectivized version of Dini's Theorem
