The purpose of this paper look at the basis of the cultural differences of Korean and Japan by comparing the craftsmanship. Korean craftsmanship and master craftsman making traditional handcrafts and artwork would die out at a critical moment. The craftsmanship and system could not be established because of discrimination in the traditional four classes of society( scholars, farmers, artisans and tradesmen), invasions of other countries and discontinuity of tradition from modernization. On the contrast, in Japan, it was possible to establish traditional handcrafts and artworks, technique and craftsmanship with apprentice system and various social privilege and treatment even in the same traditional four classes of society ( scholars, farmers, artisans and tradesmen). It was common to pass down the family business for a hundreds of years with self respect between Japanese master craftsmen and lots of people succeed the family business will now. Japanese craftsmanship is originated from 'worship to god' Medieval Japanese believed that the thing changes human mind, artistic talent, masterpieces and faith were connected to sacred power. Therefore, master craftsmen and their works were also made by the power of god. In this context, craftsmen were protected and treated in socially and nationally. It is that the social treatments and supports in national level and their own pride and continuous training of techniques and abilities as the main driving force to maintain the craftsmanship in Japan. Korea has the sale level of competitive tradition and technique in comparison any other countries. Japanese craftsmanship study will be a critical data in the protection and maintenance of Korean traditional and technique.

게이트 전류가 흐르지 않는 MOSFET를 사용한 단안정 멀티바치브레이터는 도전시에도 게이트 전압이 일정하게 유지되지 않기 때문에 이 전압을 기준으로 한 회로해석이나 설계는 매우 어려워서, 비교적 간단히 해결할 수있는 도식방법을 소개하였다. 즉 각FET의 전압이득곡선을 구하고 이 유선의 기본적인 성질과 국로 설계에 이용하는 방법들에 대해서 논하였다. In a MOSFET multivibrator, the gate do not hold into a constant clamp voltage during a conduction period. The analysis of the operation and the 43sign of a MOSFET multivibrator circuit are much more discult than that using a bipolar transistor and a electron tube because of above reason. And therefore, in the designing procedures of the MOSFET monostable multivibrator of this paper, a graphical method is adopted in order to analyze and design easily. The voltage gain curves of the both FETs are drawn using a parameter the voltage Vc across the coupling condenser, and the curves are utilized to investigate the voltages of the drains and the gates and determine the gate bias voltage. The diagram gives also important informations for the design of the multivibrator.
