This main study was the subject of the play facilities of children picnicking place which was installed in apartment complex. As to the production period of the facilities, the materiality and the materials of the play facilities, we examined the safety estimation about them. And we drew up a plan which could build and manage the children play facilities improved the better. According to the installation place, the result of safety estimation, the safety of play facilities in Ga-Kyeong-dong apartment complex which built up after 1997 years was the most excellent, the play facilities of Sa-Gik-Dong apartment Complex which built long ago have showed even poorer in all items of safety estimation. According to the materiality of play facilities, though the safety of association play rod in the safety estimation was the most excellent, the safety of swing was the very poor. According to the materiality of materials, the association of wood, stainless in the safety estimation was the safest. Especially, even though wood is soft and kind materials, as it has a shortcoming, the practical use depreciates. If iron materials like stainless associates with wood, we have thought that they have the good effect of the practical use. We have judged that the distance of contiguity facilities and the safety of corrosion or rottenness within the item of safety estimation as a subordination variable were the poorest. The arrangement of play facilities and the selection of materials happened to these problems. And we have known that they should get accomplished the construction work to make a plan thoroughly from it early.

In medium and small firm, the management system which is simple and where there is a practicality is required Ill)re than the management system which is complicated and minute of the centered around large company so that the introduction of the standard costs can be activated and it can be usefully used as a tool of management decisions. A difference between the standard costs introduction plan proposed in this paper and the preexistance study literature are as follows. In this paper, by breaking from the whole cost accounting aiming at all item, that is the traditional introduction method, and presenting the product cost accounting method by group the standards setting object was minimized and simplified. In this way, if the standards setting object is simplified, it is quick at the perimeter environment change as the little man power and flexibly it corresponds to and the cost information calculation which is exact with the setting up and maintenance of the efficient cost standard becomes available. As a result of applying for real through S corp., the usability of the method that the standard costs introduction method proposed in this paper produced the standard costs relatively short within period, it manages was verified. And the standard costs introduction method proposed in this paper went by the various cost information for each products, the management class did the management will decision which was objective and reasonable in the putting first.

Through the consensus algorithm, which is the core technology of the blockchain, the same data is accurately shared between connected nodes. The use of an appropriate consensus algorithm that considers the user and the usage environment ensures efficient maintenance of data integrity and accuracy. In this paper, we proposed a performance evaluation method for efficient selection of a consensus algorithm among authorized nodes considering the characteristics of a private blockchain platform, and applied the modified item to the existing published formula considering the number of authoritative connected nodes. Through this process, it was possible to simplify the consensus process considering the stability between nodes. The stability of the consensus process can be improved by selecting an appropriate consensus algorithm based on the proposed research.
