For the effective operation of manufacturing system, FMS(Flexible Manufacturing System) and CIM(Computer Integrated Manufacturing) system are developed. In these systems, a machine tool is the target of integration in last 3 decades. In nowadays, the conventional concept of machine tools is changing to the autonomous manufacturing device based on knowledge-evolution through applying advanced information technology in which open architecture controller, high speed network and internet technology are contained. In this environment, a machine tool is not the target of integration but the subject of cooperation. In the future, a machine tool will be more improved in the form of a knowledge-evolution based device. In order to develop the knowledge-evolution based machine tools, this paper proposes the structure of knowledge evolution in M2M(Machine To Machine) and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design the dialogue agent module in M2M environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge-evolution based machine tools can be hereafter more easily implemented.

The purpose of this study was to introduce a software task processing evaluation model that considers the following situations: i) a software system is integratedly composed of several number of modules, ii) each modules has its corresponding module task, iii) all module tasks are tested simultaneously, and iv) the processing times of the module tasks are mutually dependent. The software task completion probability with the module dependency was derived using the joint distribution function of Farlie [11]. The results showed that the task completion probability of software increases with increasing module dependency parameter.

Recently, the conventional concept of a machine-tool in manufacturing systems is changing from the target of integration to the autonomous manufacturing device based on a knowledge evolution. Subsequently, a machine-tool has been the subject of a cooperation through an advanced environment where an open architecture controller, high speed network and internet technology are contained In the future, a machine-tool will be more improved in the form of a knowledge evolution based device. In order to develop the knowledge evolution based machine-tool, this paper proposes the structure of knowledge evolution and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation.

New RF matcher module has been proposed in this paper for improvement of RF matcher in plasma etcher system using in semiconductor and display panel manufacturing process. New designed warm gear was used instead of bevel gear in new driving module, and control system was re-arranged with one-chip micro-process technique. The matching performance of new match module was improved in various process condition with reduction of backlash and matching time, and flexible motion of motor compared commercial match module. However this new type RF match module will improve the productivity in etching process of the mass production line.

The advancement of information and communication technology has caused a few dysfunction such as hacking. To keep an organization from a harmful hacking, demands for cryptographic modules have been increased. However, the evaluation criteria of cryptographic modules in Korea have been less firmly established. It is difficult for the consumers of cryptographic module to choose an appropriate cryptographic module, and to establish interoperability between applications and cryptographic modules. This study analyzes evaluation criteria, evaluation processes and evaluation policy of CMVP(Cryptographic Module Verification Program) in the advanced countries. The paper suggests a policy for Korea CMVP, in resulting a provision of foundations for international standard and cooperations for international cryptographic policies and systems.

The use of the PMP (Protection Module Package) was proposed as a solution for the shorter battery lifetime. The PMP means that a protection circuit consists of a semiconductor single. In this study, basic research was carried out to select a suitable epoxy material of the EMC module through finite element analysis. First, the stress on the external force was compared by the flexural strength analysis. In the following thermal analysis, the temperature change of the EMC module and the internal part was compared using the calculated heating value. Finally, the filling ratio was compared with the injection of the melting epoxy in the EMC module.
