Succeeding the study as introduced in the last report, this research shows the details of structure of community, centering round direct communication, the medium which unites individuals into an collective body. Two channels of communication can be noticed in regional groups in urban areas : one is through the channel of neighbourhood; the other through certain indirect communication media. The former has the more of the nature of community communication which remains unliquidated in the process of urbanization; and the latter is a uniquely urban phenomenon. These two are quite incompatible with each other; and the original idea of community carries the former way of communication. However, this original community communication channel of neighbourhood has possibilities of rebirth through collective movements even within a region where neighbourhood channel is no longer available, for the inevitable regionality of the movements reclaims the channel of neighbourhood in a specific scope within which efficient operation of communication channel can be obtained. The communication channel through indirect media, however, no longer limits its sphere within regional bounds, but takes care of city-sized or intercitysized communication. Thus, as revealed in this research, each of these two natures of human unity in urban areas is unique in its size or its pattern of relation of dwellers, and uniquely determines the material and external features, for instance, the structural features of its public institutions which the dwellers demand, such as assembly halls.
