The major issues of managing an organization and its environments are on how to establish a community for their co-survival and collaboration. This study is on the principles and management practices for establishing the community of organization and its environments based on the power circulatory approach, so that it contributes to creation of the social orders for co-survival and collaboration. In order to do this I discussed the theories and practices of the power circulatory approach, and then suggest their application to establishment of the co-survival community for organization and its environment. According to results the power circulatory approach offers theoretical and managerial tools which establish the co-survival community for organization and its environments, so that it increases likelihood of their co-survival and collaboration. Furthermore I discussed the position of the power circulatory approach to co-survival and collaboration in a manner that displays similarities and differences with exiting approaches such as the contingency and population ecology model.

In this study, in order to minimize the increase in the amount of various industrial by-products due to the rapid growth of the industry and the intensification of the depletion of natural aggregate resources, the material test using recycled aggregate and steelmaking slag and the proper mixing ratio of recycled concrete were to be derived. In this study, first, the conformity of the quality standards of the materials used in the field was confirmed, and the workability and molding results were shown when used alone or mixed. Therefore, the feasibility of application as aggregate for concrete was evaluated through a total of 4-type mixtures of cement types, admixtures, coarse aggregates, and fine aggregates. As a result of the experiment, it was confirmed that the slump of unhardened concrete, the amount of air, chloride and compressive strength of hardened concrete according to the replacement rate were different from the measured values of general concrete quality characteristics. According to this, it was confirmed that the quality characteristics of the standard design criteria were satisfied.
