In order to investigate the dynamics of powder snow avalanches, the experiment on fronts of gravity currents on the inclined wall is carried out. Experiments concerned are inclined thermals using saline water and turbid water into fresh water. The saline gravity current is conservative and turbid one is non-conservative. The speed and the maximum height of the front of gravity currents are measured for all cases. The salinity concentration profits are measured for the case of saline gravity currents. The non-dimensional speed of saline inclined wall plumes and thermals are nearly constant in the flow direction. On the contrary, the non- dimensional speed of turbid inclined thermal decreases in the flow direction.

The development and practical application of the falling weight deflectometer (FWD) which is a nondestructive testing equipment to define the shape of deflection basin, are described. The estimation of the structural condition of the pavements in Nagaoka city, Niigata prefecture is performed. The procedure is based on multilayered elastic theory to backcalculate elastic moduli from FWD deflection data. The study has indicated that it is possible to evaluate structural defect without destroying the pavement.

Many Japanese orchestras have difficulty thriving due to the lack of adequate subsidies, the abundance of competition or the inability to attract new patrons In order to grasp a common problem in Japanese orchestras, we investigated fiom the viewpoint of organization and management, having used mainly eight Japanese orchestras as the case study We conclude the solution of their problems on three levels, governance, business and management In governance, we insist on the necessity of increasing subsidies for art and a taxation system with good tieatment to donations In business, since income and expense is not well balanced, income increases and cost reductions must be carried out In order to increase income, they have to aim at not only ticket sales but the income expansion of those other than a mam business, symphony gift shop It is also necessary to cut down the personnel, especially artists' expenses with the heaviest burden in orchestra for cost reduction Finally in management, the big issues are marketing and consistent perfoimances Japanese orchestras have performed marketing foi new customers eagerly However, marketing is indispensable in order to survive For consistent and high quality performances to attract the audiences, executive director will become more important, who has the responsibility for strategic management to solve organizational dilemmas between economics and professional artists

The overturning of a motor vehicle passing along Route 8 at Yoneyama along the Japan Sea coast is reported to have occurred on 29 October, 1976, due to a strong onshore wind. This paper reports a model study aimed to elucidate the mechanism of this incident. The model terrain and vehicle were scaled down to one to 30. Wind velocity, pressure distribution along the terrain as well as model vehicle are measured, and the drag and lift force and the overturning moment of the model vehicle are calculated. The result of the study points to the possibility of studying the mechanism of overturning accident.

Cultural administration in Japan matured in the 1980' s. It was partly because people had begun to seek not only material affluence but spiritual and personal fulfilment after going through the experience of environmental pollution, and partly because a rapid increase in interest among Japanese in culture and cultural pursuits expected much of measures concerning cultural affairs to the government and the local authorities. The key words that promoted the cultural administration in those days were "Age of Culture" (Bunka-no-zidai)and "Age of Local Areas" (Chiho\^^^-no-zidai). There two words are significant and meaningful in cultural policy of today. In this paper, I want to make clear why these key words had been professed in the 1980' s and how those had functioned on cultural administration.
