It is important to get the objective evaluation of human sensation for vibration. The one of the methods is to use the vibration contour for human sensation standardized by ISO. It explains the relation between the frequency and the vibration level at a certain frequency range where the subject feels those vibrations in the equal strength. This study investigates the vibration responses of the human body at the equivalent strength to understand why they feel those vibrations equal. As a result, an average contour of plural subjects for human sensation becomes similar to the contour standardized by ISO. The conditions of human vibration change at about 10Hz.

In this study, the vertical jump is examined as a basic study of jump. And we examine the influence of each muscle of the human body in vertical jump. The human body is modeled as four rigid bodies and analyzed in detail by using the model that includes muscles of the leg. In this research, the mechanism of jump is discussed by using numerical model to which the concept of multibody dynamics and biomechanics is adapted. We performed the experiment of jump and observe the feature behavior of vertical jump. Experimental results show that the angle of each body becomes vertical for ground and the change of the foot angle is small. Then we perform the numerical simulation referring to this experimental data. In order to reduce the amount of calculation, we calculate muscular activity level by correlating it with fewer parameters. We discuss which muscles are necessary for vertical jump. It is found that vasti exerts the biggest power and gluteus maximus has the highest state of normalized muscle activity.

Media has been transforming its shape rapidly due to the fast development of information technology. Up until recently, so-called "mass media" had been enjoying the privilege of gathering information and disseminating it to the public. Now, mass media's monopolistic manners have been gradually eroding and concerned groups and individuals, empowered by the introduction of new technology, are gravitating towards the media's sphere. Even though we don't have the established term for this situation of the media, there is no doubt that the practitioners of the media are no longer limited to the "media professionals, " but have widened its boundaries to the non-professional individuals. One of the tools that have made it possible has been the proliferation of the WWW (World Wide Web). Its versatility is a great advantage for those who wish to publish something for the public. People who are not satisfied with being a recipient of information are using this opportunity to become providers of information. This indicates an emergence of regional journalism where residents can discuss and publish their concerns and interests without the aid of conventional media. In this paper, the authors would like to show the actual example of "Civic Media, " where the authors belong, which is practicing civic journalism in Sapporo. Discussion will be focused on how this movement was founded in the region and how its members have acquired community awareness through its activities.
