箱庭療法やMSSM（交互ぐるぐる描き物語統合法）などの表現療法では，心理療法の進展に伴い，変容の鍵となるようなイメージが現れ展開する。本稿では，不登校男子中学生が心理面接の中で，箱庭療法やMSSMで表現したイメージについて検討した。クライエントは，初回箱庭で砂漠での遭難をイメージし，初回のMSSMでは「伝説の卵を探す旅」の物語を作った。それらのイメージは変化し続け，彼も変容し，最後には統合の物語が作られて面接は終結した。クライエントの変容と，表現療法の中でのイメージの変化は，同時的に生じていた。本稿では「卵」イメージを中心に，「思春期内閉」と「孵化」の観点から，心理療法でのイメージの働きについて考察した。

The purpose of this article is to analyze the business development and entrepreuriship of Japanese computer game companies such as SEGA, Namco, and Nintendo.
Until the 1970's, these firms were all once small manufactures of amusement machines or toys. How did such relatively small firms in the urban area grow up to be the profitable corporations we see today?
The first step is to analyze how they have been as the leading companies in the fragmented computer game market which has been characterized by frequent changes with increasing speed since the formative years of the industry. Nintendo, the first mover, created its business system based on the strategy of outsourcing in software production and quasi-integration of distributors as “Shoshinkai”. SEGA and Namco tried to attack Nintendo's system using the strategy of building internal software development capabilities, which generated software production organizations which are, in using Michael Cusumano's terminology, 'software factories'.
The second step is to analyze the mechanism of the 'software factory' as in the case study of 'AM 2 ken' (the 2nd R & D division of arcade machines) of SEGA. Its origin is intrafirm venture business in the crisis era of the arcade game market in 1985. AM 2 ken has been developing and driving SEGA's innovation since then. Its software production is done by small cross functional teams, and its advantage is based on the communication 'on the shop floor', where old business resources and new technologies are combined. It enabled gestalt change from 'waterfall' model to 'revise' model in grasping the process flow of software production.
The study shows that small manufacturers in the urban area pzoneeringly introduced basic hardware technology from US in 70's and created the new market by developing and concentrating on the innovation of software and contents. In this way, relatively small firms could grow by bypassing the demerit of economy of scale. Here is the logic of 'small is storong'.
