Compared to other methods 4 A Model on Kansei Engineering in Aective Engineering, Kansei Engineering is the only Methodology method that can establish and quantify connections be- tween abstract feelings and technical specications.
For every Kansei word a number of product properties are In Japanese publications, dierent types of Kansei En- found, aecting the Kansei word.

The research into constructing these links has been a core Choice of Domain part of Nagamachis work with Kansei Engineering in the last few years.

Some of the most common tools are : an assembly of products, i.

From this, a domain description is formulated, serving as the basis for Genetic Algorithm further evaluation.

The Critique of Pure Reason Kritik der reinen Vernunft ; second edition is a book by the German philosopher Immanuel Kant , in which the author seeks to determine the limits and scope of metaphysics. In the preface to the first edition, Kant explains that by a "critique of pure reason" he means a critique "of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience " and that he aims to reach a decision about "the possibility or impossibility of metaphysics". Kant builds on the work of empiricist philosophers such as John Locke and David Hume , as well as rationalist philosophers such as Gottfried Wilhelm Leibniz and Christian Wolff. This is argued through the transcendental idealism of objects as appearance and their form of appearance. Kant regards the former "as mere representations and not as things in themselves", and the latter as "only sensible forms of our intuition, but not determinations given for themselves or conditions of objects as things in themselves". This grants the possibility of a priori knowledge, since objects as appearance "must conform to our cognition

Sociology as a Science
In the time of Enlightenment the idea of science was to promote the Good society. There was yet not perceived to be a contradiction in science between at the same time being objective and progressive. The response from the scientist was paradoxically Technology and Society Luela to defend objectivity. Thus when sociology was established as a science around the University of Technology SE year it became inherently contradictory, i. The conclusion is: by taking understanding as the point of departure sociology can be progressive: promoting the good society and still be a science. Author s. This is since the time of Enlightenment - the meaning of science cf.
