한국산 머리파과 계통분류의 일환으로 북한에서 채집된 머리파리류를 동정하던 중, Eudorylas속에 닮았으나 지금까지 알려지지 않은 새로운 속에 속하는 4신종을 발견하였기에 기재 보고코자하며 다음과 같다. Moriparia gen. nov.(머리파리속, 신칭), M. alata sp. nov.(날개머리파리, 신칭), M.amica sp. nov.(친구머리파리, 신칭), M. spinosa sp. nov.(가시머리파리, 신칭) 및 M. nigripennis sp. nov.(검은날 개머리파리, 신칭).
Soybean was originated from the regions of Manchuria where it was processed into Dujang, the fermented soybean souce. It was not until the Han dynasty in China that 'Shi', one type of Dujang, was introduced. 'Shi', which is also known as 'Sanguk'(loose soybean Meju), is made by first boiling and then fermenting the kernel of cooked soybean. It was admitted by the Chinese scholors that the 'Shi' which was used in China was introduced from Manchurian, the neighboring people to China at that time and the concestor of Korean. 'Maljang' is a form of caked-shaped 'Meju' which is made by formenting cooked and mashed soybean. The 'Maljang' of Manchuria was introduced to China, where it was called 'Maldo'. This fact is stated in a book, 'Saminwolyong', written during the 2nd century. 'Maljang' is presently used in Korea, but China has abandoned the use of 'Maljang' since the 6th century. It was introduced to Japan from Korea around the 7th century, and is remained in a few local regions. Although the term 'Jang' is representing all sort of fermented soybean preducts, including 'Shi' and 'Maljang', today, the definition of 'Jang' differs between China and Korea. According to the Chinese definition of 'Jang'. it is fermented soybean mixed with other cereal Koji. 'Jang' was first mentioned in 'Jaeminyo sool' in China and it was lator introduced to Japan However, in Korea, the Chinese type of 'Jang' was not commonly used due to the popularity of 'Maljang'.
비선형의 특성을 갖고 있는 DC 서보 모터의 속도 제어에 퍼지 제어기의 사용을 제안하였다. 퍼지 제어기는 퍼지 모델로부터 설계되며, 그 퍼지 모델은 시스템의 입출력 데이터로 인식되고 비선형 시스템의 표현에 뛰어난 능력을 갖고 있다. 따라서 퍼지 모델로부터 설계되는 퍼지 제어기는 시스템의 비선형 특성이 잘 반영되어지며 그러한 점은 서보 모터의 속도 제어에 응용한 결과 잘 알 수 있었다. 즉 퍼지 제어기에 비해 고속 제어가 가능해졌으며 정상 리플(ripple)이 감소하였다. 또한 이 퍼지 제어기에서 사용되는 퍼지 집합의 멤버쉽 함수는 간단한 선형 구분 함수이므로 퍼지 제어기도 간략한 형태로 표현되었다
