본 논문에서는, 복수의 사용자가 MH 공개키 시스템을 이용하는 경우, 복수의 개별키에 공통으로 적용할 수 있는 마스터키를 새로이 제안하여 보도하였다. 이러한 마스터키를 시스템내에 도입하면 개별키의 크기의 총화보다 작은 마스터키를 선택하여 기억용량을 절약시킬 수 있고, 디지탈서명에 의한 인증이 용이해진다. 또 RSA 공개키 시스템과 비교해 볼 때, 마스터키를 사용하더라도 개별키를 사용할 때에 비해서 처리시간에 큰 영향이 없음을 컴퓨터 시뮬레이션에 의해 입증하였다.

Special quality of automobile clutch master cylinder(CMC) and analyzed aluminum, plastic material comparison. Efficiency of plastic master cylinder can modularize higher, light weight anger of parts, several piece parts by single parts, prove NVH(Noise, Vibration, Harshness) than aluminum master cylinder as analysis result. Also, structure is easy simplicity, exchange, maintenance costs can be reduced and decrease environmental pollution because recycling is superior. According as content of glass fiber increases, mechanical properties of matter of material increase equally and glass fiber changed variously by condition on manufacturing process. Through comparison analysis with Plastic Body development connection site, did verification.

The characteristics of rubber cup seal is highly nonlinear due to the nature of the material's non-linearity and large deformation with frictional contact. And the performance of sealing in master cylinders of automobile is one of the most important factors which affects the safety of drivers. The effects of various shape of the primary cup seal in clutch master cylinder was investigated to reduce oil leakage and to obtain a long reliable life. Deformation and distribution of stresses on the primary cup seal against hydraulic oil pressure were analyzed with changing design parameters such as depth and radius in cup-seal. The obtained results indicate that the depth of cup seal plays a major role on deformation resulting in the sealing force to the wall of clutch master cylinder.

This report is that the scenery of the town with a different measure is different. There are the framework and the story in the rural communities master plan . This master plan's story intends the self-help and living with meaning of citizens in own city and town. It is the philosophy of the master plan that citizens' daily bread is the local resourses, lives in safety and keeps the healthy living. But these contents are the different means by the condition of each cities' and towns' geography. The scenery of introducing two towns appears to each different plan by different conditions.

Load master is authorized to be controlled all of loading stuffs for safety of flight such as passenger, baggage, cargo and e.t.c. There are many things are missed even though the weight and balance is the most important process. This study analyzes how the differences of C.G. by among ten load masters of each careers. This study is tested how load-master takes load-control by the respective result based on differences of each practical experiences, gender and a number of certification. In result, all of load masters set C.G. on the stability region. But the practical experience of load master is relative to set better C.G. for economical effectiveness of weight and balance control work.

Master-slave (M-S) strategies implemented with chain circuits are the main option in order to distribute clock signals along synchronous networks in several telecommunication and control applications. Here, we study the two types of masterslave chains: Without clock feedback, i.e., one-way master-slave (OWMS) and with clock feedback, i.e., two-way master-slave (TWMS) considering the slave nodes as second-order phase-locked loops (PLL) for several types of loop low-pass filters.
