Abstract: Provided is an air cleaning system including: an ozone generation unit that generates ozone gas; and a discharge unit that atomizes or vaporizes an aqueous alcohol solution and discharges the aqueous alcohol solution. A mole fraction of an alcohol included in the aqueous alcohol solution with respect to the aqueous alcohol solution is 0.05 or more and 0.35 or less. A hydroxyl radical is generated through a reaction of the ozone gas with the aqueous alcohol solution that has been atomized or vaporized.

Abstract: A value chain flow diagram expresses the flow of money, things, claims, persons, information, services, values or the like related to the lifecycle of products (planning, designing, manufacturing, distribution, sale, use, disposal) which are generated among enterprises, departments of an enterprise, clients, users, stockholders, authentication organizations or regional inhabitants. In the product value chain flow diagram, individual components such as the enterprises, the departments of the enterprise, the clients, the users, the stockholders, the authentication organization or the regional inhabitants are expressed by block shapes such as boxes and circles and the flow of the money, the things, the claims, the persons, the information, the services, the values or the like is expressed by specific symbols or linear or curved arrows labeled with icons. Further, the components which are expressed by blocks are connected with each other.

Abstract: There is provided a project risk management method by using a Failure Modes and Effects Analysis (FMEA), comprising the steps of: inputting tasks (work items) of a project; generating a process model having information representing dependence relations among the tasks, information about an output of each task and information about a resource necessary for executing each task; and generating an applicant list of a failure mode by looking up the process model.
