In recent years, group work has become popular in education, and studies for the suitable environment are required. In this study, to clarify the part of the environment in which users ask for group work, focusing on the table. We let users do group work and design desks through experiments, and we produce prototypes those desks. After that, examine the awareness when they design desks and user satisfaction when they use them. Findings are considered to help improve the environment of group work techniques and furniture design in the future.

  In a human error study, new knowledge to prevent an office work error is demanded. An office work error is an error to happen when it cannot put unsureness of the work in a range without the problem.

  In this paper, I arrange the example of the office work error that I investigated by the hearing to the A junior college. And I classify factors to cause an error to lead to an office work error systematically and clarity each problem. In this paper, I adopt a theory of Reason about a factor to cause an error, the type of the error. As a factor to cause an error from the result of the classification, six became clear. The six are time pressure, manner of “can do”, documentation, insufficient communication, inexperience, task frequency.

  Therefore I think that it leads to the prevention of the office work error to assume a factor to cause six errors a chief problem.

  This paper is reported on the results of the site visit surveys, interviews with the master of the Fabrication Sharing Space for the Personal-Fabrication, and, in the most characteristic facility, the stay surveys. The goal of these surveys is to contribute to a better workspace design. These surveys revealed that such a space is required to be able to communicate with others and a variety of activities beyond Personal-Fabrication.

  This Study is focused on “Color” that expresses a corporate identity and stimulates the creativity of office workers. It is also looking for a possibility of practical use of color in Office Space. Recently, the office functions not only as “a Location for Working” but also plays the role of “the Corporate Image Brand”.

  This paper describes results of research A) and B), and changes a direction of interior design process.

  A) A research of method of use of color in Office Space based on photos of 135 case studies.

  B) A comparison of two surveys done in 1986 and 2010, on 213 employees, which shows the influence of difference color use on office employees.
