What we call the present society 'the knowledge centered society' is because the knowledge centered information determines our survival. 'Knowledge centered society' means that the value of economic activities is changing from the form of a concrete resources to the form of a metaphysical resources. The metaphysical resources means the various formless information which human beings create. As these metaphysical resources directly connect with an economic value we can say that they lead a radical social changes. We need diverse human resources to adapt ourselves to a social changes and to create new information effectively and to utilize them. Under the existing uniform educational system, we have difficulty in training diverse human resources effectively. Therefore, it is a general tendency to make various policies, to establish related laws from necessity and to improve a social environment for the effective human resources development. At present, human resources development and training are becoming a competitive power for the national survival. In our country from 2000, we have supported the full-scale research and policy-making which are necessary for the human resources development. we established 'Basic Human Resources Development Act' in 2002. 'The Basic Human Resources Development Act' is the process of embodying the realistic human resources development plan through the improvement of a present educational environment. It is to make a legal basis for forming an effective political support system for the purpose of the effective human resources training and utilization. Various forms of verification need to make an effective human resource training system by 'Basic Human Resources Development Act'. We have to grope a concrete method to coincide in 'the Basic Human Resources Development Act' which was established with the object of human resources development.

Abstract When a sheet steel plate is under the action of local lateral load, it simply deformed plastically. This study has made to investigate the behavior of he plastic deformation of carbon sheet steel plate subject to a concentrated load. The measured experimental results is compared with the theoretical output, and they agree well.

This study aims to clarify the behavior of fatigue crack propagation through observation and study on the fatigue crack propagation, its propagation rate and stress intensity factor. The results obtained in this study are summarised as follows; 1. According to the study, it is said that no effect is influenced on the fatigue endurance by stress concentration factor of a bar with transverse hole of spring steel if diameter of hole is 1mm or more. The effect of hole diameter is influenced in spring steel if diameter of hole is 0.5mm or more through present experiment. 2, On the crack initiation in the vicinity of the transverse hole, the slip band is generated and accumulated to the direction of maximum shearing as the bending stress level becomes low and it grows up the micro-crack. 3. The fatigue crack of spring steel is initiated after 10∼20% of the fatigue life and spent almost fatigue life by crack propagation.
