There has been a tendency that the hi story of design is described with focus on design outputs rather than on what lies behind the outputs. This study examines the history of design thorough the changes in nature of design methodology used by designers in each age, instead of focusing on de sign outputs. First of all, assuming that the design methodology evolves around certain change factors such as a product , a user and a designer from the diachronic perspective reflecting social phenomena of the age, we analyze how it has evolved through th e ages and research into the related cases. As the concept of the product is changed from an industrial product of physical properties to a digital product of virtual properties or a product combined with environment, more items need to be taken into cons ideration when selecting a design methodology such as usability, target user, service contact, platform, and ecological perspective. In addition, as the users have become active and positively involved in design and equipped with their own design capabilit y, the design methodology that utilizes collective intelligence or involves the user directly into the design process has been devised. As for the designers, the scope of design has become wider to an extent that they have to design the concept of a produc t, its interaction, contents, service contact and system in general, not to mention its physical appearance. Therefore, integrated thinking and decision making have become an inevitable part of design and the scope of the designer's work has been expanded to the overall product development process. This study aims at analyzing and summarizing the age specific characteristics and evolution of the design methodology within the context of correlation between the design methodology and change factors. It is expected that this study can help find useful design methodologies for the future, as a basic research on the development of the design methodology from the historical dimension

Our study in this paper aims to show railway stations’ experiences for stroller s from the point of users’ view To approach this purpose, we propose a visualizing web application to archive the views of railway stations experiments between stroller users and other people. We create a system to collect the views from Twitter and our own contribution system We apply language analysis to the views and extract users’ sentiment and key phrases. In addition, we visualize these views to overview with sentiment and key phrases simultaneously. We consider that our work will give a better understanding of various inconveniences for s troller users , and propose guidelines of what kind of behavior and understand ing are required for each other .

I n Right now, population of the world is increasing rapidly day by day, and as it will in the future. Large numbers of people gathered in a city which makes the city grow into a megacity. Especially in East Asia, according to the survey of population in the world, we can see that most of cities in East Asia have extremely high density and population. Most of people come to city to find a job, and work is the biggest source of stress, also past studies have shown people who live in a megacity get stressed easily as crowded and polluted environment. We need to deal with the stress, or it may cause some serious health problem. The objective of this design project is to create a modular space which provides relaxing time for the people who live in a megacity of East Asia, an example of new lifestyle.
