摘要:
Novel cyclic adenosine monophosphate derivatives represented by the following general formula: ##STR1## wherein A stands for --S-- or --NH-- and n is an integer of from 2 to 12, ARE SUPERIOR TO KNOWN CYCLIC ADENOSIENE DERIVATIVES IN BIOLOGICAL AND PHARMACOLOGICAL ACTIVITIES, ESPECIALLY PDE-inhibiting activity and membrane permeability. Accordingly, these derivatives are very effective for remedying and controlling diseases caused by disorder of the intracellular cyclic adenosine monophosphate level, such as asthma and scabies. These derivaives can readily be synthesized by reacting an 8-halogeno cyclic adenosine monophosphate of the following general formula ##STR2## wherein X is a halogen atom such as bromine, with an alkali metal salt of a linear alkylmercaptan having 3 to 13 carbon atoms in the alkyl group or a linear alkylamine having 3 to 13 carbon atoms in the alkyl group.

摘要:
Simulation for evaluating approval/rejection of an action plan of the type in which work breakdown struction is changed by influences of external risk factors is achieved. A simulation apparatus includes a plan/risk input portion for accepting input of action plan data and risk scenario data, a plan/risk simulation portion for conducting simulation of an action plan by using the action plan data and the risk scenario data so accepted, and a plan evaluation output portion for evaluating a simulation result. The plan/risk simulation portion simulates occurrence of a risk phenomenon by using the risk scenario data, determines influence information given by the risk phenomenon to the action plan when the risk phenomenon is simulated as occurring and conducts simulation of the action plan by reflecting the influences of the risk scenario on the action plan by using the influence information so determined.

A project pre-review estimate method capable of estimating influence of alteration in each process of a project on the whole process (project) considering structural alteration and fluctuating values regarding each process and their factors is provided. The project pre-review estimate method is carried out employing a process evaluation procedure which calculates quantitative and structural alteration amounts of the process plan using not only information on constraints (which has been used by conventional techniques) but also scenario information (in which probability of occurrence of a risk (i.e. a factor of alteration to a process) and the content/degree of influence regarding alteration of arbitrary processes caused by the occurrence of the risk are defined in a scenario format) and information for correcting parameters of the scenario by use of qualitative information on the project.

In a graph displaying method for displaying as an analysis subject a collection of constituent members each having a plurality of information parameters, each information parameter of each constituent member is assigned to a display attribute of graphic representation, and a value of the information parameter of each constituent member is converted into a value of the assigned display attribute. Next, a display corresponding to the information parameter of each constituent member is provided by using the converted display attribute value. Then, the value of each information parameter indicating affiliation between constituent members is converted into the display attribute value of a display element which couples display elements of the constituent members, and a display corresponding to the affiliation between the constituent members is provided by using the converted display attribute value.
