<p>This paper describes behavior of the jump robot which is connected by tether. The internal environment of the hole existing on the moon is not clear and is expected to be investigated. For research of the unknown environment, exploration is planned using a rover with umbilical tether connecting a mother rover near the hole. Then, it is important to study how tether influences jumping behavior of the rover. Equation of motion and differential algebraic equation is formulated by the use of Absolute Nodal Coordinate Formulation (ANCF) and multibody dynamics. Rover is regarded as two bodies with slider joint. Telescopic motion of spring expresses effect of jump. Numerical analysis reveals the relation of jumping behavior and parameters, and is compared with experimental result.</p>

The authors attempted to confirm the necessity of free shared spaces at schools and researched the function of such spaces in four junior high and high schools where free shared spaces were intentionally planned and built about 30-35 years ago and are still being used today. We also distributed a questionnaire to 100 Showa Women's University students, some of whom are graduates from the schools with free shared spaces mentioned above, asking about free spaces at their high schools: how they are used and what type of free space they felt they needed during out-of-class time while at high school. Observation of the spaces at the four schools revealed the usefulness of the spaces as venues for communication among small groups of students. In addition, the researchers found that other spaces, like corridors and staircases, were also used as free shared spaces, that large free spaces were effectively used as venues for school events and for preparation for those events, and that free spaces near students' home rooms were frequently used. The results of the questionnaire also support the necessity of such spaces on the grounds that students' satisfaction with their school life is related largely to school events, friendship, and club activities, and that satisfaction with the school buildings in which these activities take place correlates to the availability of these free spaces.
