Abstract
Purpose
The purpose of this paper is to investigate the blood flow and temperature distribution in human extremities.
Design/methodology/approach
The simulation is carried out from three aspects. Firstly, the hemodynamics in the human upper limb is analyzed by one‐dimensional model for pulsalite flow in an elastic tube. Secondly, the blood flow and heat transfer through living tissues are described basing on porous media theory, and the tissue model is coupled with the one‐dimensional blood flow model. With respect to geometric modeling, MR‐image‐based modeling method is employed to construct a realistic model of the human finger.
Findings
It is found that the temperature variation is closely related to the blood flow variation in the fingertip and the blood flow distribution in the tissue is dependent on the locations of large arteries and veins.
Originality/value
Blood flow and temperature distribution in a 3D realistic human finger are firstly obtained by coupling the blood circulation and porous media model.

Abstract
In this second part of the report on Printed Circuit World Convention IV held at the Tokyo Prince Hotel, Tokyo, from 3–5 June 1987, a general synopsis of the content of the papers presented in the eighteen technical sessions will be given. As three sessions were run in parallel throughout the 2½‐day conference, and therefore not all presentations were heard by those reporting on the technical programme, a number of them have been briefly summarised from the Convention Proceedings.
