By using the DEA, technical efficiency, pure technical efficiency, and super-efficiency were analyzed. Food industry statistic information of the FIS was employed for the reference. Furthermore, input variables were total asset, number of employees, selling and administrative expenses and compute variables were sales, operating profits, and net profits. First, according to the primary analysis results, the descriptive statistics of the food service industry were higher in western restaurants on average. Second, the technical efficiency was 0.6634, the pure technical efficiency was 0.7640, and the scale efficiency was 0.8741. Moreover, the technical efficiencies of Korean food and other food restaurants were lower than the average whereas those of canteens and western food restaurants were high. Third, a restaurant which has an efficiency of 1 had 10 technical efficiencies and 15 pure technical efficiencies and an efficiency rank was classified by using a progressive marginal analysis. Fourth, efficient restaurant chains injected less amount into the total asset, number of employees, and sales and administrative expenses compared to inefficient restaurants. Also, in the group efficiency comparison, canteens had higher technical, pure technical, and scale efficiencies whereas Korean restaurants had lower efficiencies. Based on the analysis results, implications for administrative improvement of the food service industry can be suggested.

Allotment gardens in Japan began for recreational purposes. However, recently, allotment gardens are viewed from the perspective of farm managers as a part of agricultural business management with the benefits including prevention of fallow ground, voluntary service activities and profits from the cost of using the gardens. For urban residents, allotment gardens are a means to partially participate in farm management or a space for experience-type farming activities. From these viewpoints, allotment gardens have a high possibility of community activation and of assisting people in accepting agriculture as a part of life. This study aimed at discussing the aspects of allotment garden developments in legal and systematic viewpoints and at analyzing key contents of a reference area. The results are as of the following. First, allotment gardens in Japan are being developed systematically under the related laws and systems. In addition, allotment gardens in Japan are installed in various ways, such as by local public organizations agricultural cooperative associations or according to the status of owning farmland or not owning farmland. Second, allotment gardens in the reference area are located in an urban district and are mainly used by the senior citizens. The allotment gardens are being maintained and developed through the activities of self-governing organization among the users.
