윤규택,이동주,최만용,박해원,박정학 한국공작기계학회 2002 한국공작기계학회 춘계학술대회논문집 Vol.2002 No.-

An automobile hub is composed of a hollow cylindrical part with inner and outer diameters. These hub diameters must be precise, as any irregularities in them (diameters) can influence/degrade the motion of an automobile with this problem. Highly accurate and reliable hub inner and outer diameters measurement systems are therefore required for inspection of the diameters. In this research, an automobile hub inner and outer diameters measurement system has been developed and tested. The system consists of measuring heads with LVDT sensors, and associated software for automatic measurement and calibration of the diameters and the sensors respectively. The system has been evaluated in comparison with an existing measurement system, and the following outcomes have been achieved; ·Improved and guaranteed quality and reliability ·Increased productivity and cost reduction These results prove the system developed in this research to be suitable for automobile hub inspection.

최만용,박정학,윤규택 한국비파괴검사학회 2001 한국비파괴검사학회지 Vol.21 No.6

정밀부품이나 기기는 개발과정이나 완료단계에서 부적절한 설계에 의하여 발생할지도 모르는 잠재적인 결함을 방지하기 위하여 시험평가를 실시하게 된다. 본 논문에서는 신뢰성 기술 분야의 기초가 되는 환경시험기술을 소개 하였으며 엔코더, 교통신호제어기, 계측기기 및 위성항법 수신기 등 제품단위의 대상품에 대한 시험조건 및 방법 등을 기술하고 시험사례를 보고하였다. 이러한 사례를 통하여 제품의 신뢰성 향상을 위한 복합환경시험의 중요성을 강조하였고 최근 환경시험기술에 대한 인식이 날로 증대되면서 시험기술자 양성, 지그설계기술 그리고 고장해석 및 대책기술의 확보가 매우 필요함을 제안하였다. Precision parts and instruments are tested to evaluate performance in development-process and product-step to prement a potential defect due to a failure design. In this paper, Environmental test technology, which is the basis of reliability analysis, is introduced with examples of test criterion, test method for products, encoder and traffic signal controller, and measuring instruments. Recently, as the importance of the environmental test technology is recognized, It is proposed that tranining of test technician and technology of jig design and failure analysis are very essential.

kyu-Tek PARK 한국응용곤충학회 1996 INSECTA KOREANA Vol.13 No.-

루마니아의 수도 Bucharest에 있는 “Grigore Antipa" 자연사박물관에 소장된 A. Caradja의 뿔나방과 모식표본(Type specimen) 40여종 중 현재까지 보고되지 않았던 21종의 암수생식기를 검경, 이들을 도해하였으며, 그들의 분류학적 위치를 재정리하였다. 타 연구자들에 의해 이미 생식기검경이 이루어졌던 13 종에 대해서는 그들의 분류학적 지위가 논의 되었으며, 금번 조사기간중 표본점검이 누락된 나머지 5종은 간단히 그들의 표본정보만 수록하였다. 본 조사결과 5종은 다른 속으로 이전, 재조합(comb. nov.)이 이루어졌으며, 4종은 새로운 synonym으로 정리하였다. Male or female genitalia of 21 species of Gelechiidae described by A Caradja are dissected and illustrated, with discussion on 34 type-speciemens for their taxonomic status: five species are newly combined, and five species are proposed to be new synonyms.

Discovery of 500 New Species, with Taxonomist’s Contributions Needed in Facing with the Global Warming

Kyu-Tek Park 한국응용곤충학회 2013 한국응용곤충학회 학술대회논문집 Vol.2013 No.10

Since Linneaus (1758) named 4,162 species of living organism, 1.75 milion species have been described and named. It is less than 20% of the commonly accepted estimates of 10 million species on the planet earth. An average of 7,000 species per year was described during last 250 years, and, at this rate of species description, it will take another 1400 years to complete documentation of them. Who will do it? The real facing problem is the number of trained and practising taxonomists is declining worldwide at a time when demands for taxonomic science are increasing. A recent estimate suggests that the number of professional taxonomists worldwide is only 4,000-6,000 (Haas and Hauser, 2006). How about the situation is in Korea? In addition, the change of weather and the global warming accelerates more frequent invasion of harmful subtropical species, and taxonomist’s activity is needed more than ever. In shortly speaking, we are facing with a taxonomic “crisis” with erosion of taxonomy during last decades. The major reason is maybe that systematics has made little impact on the science with a narrow intellectual perspective, and most taxonomists have become accustomed to working on their speciality taxon without concern for relating their work to other broader environmental and societal issues in the facing with the global warming; e.g., invasive species, quarantine, use of bioresources, and ecosystem services. There is no question that taxonomy is the fundamental disciplines of biology, however, first of all, taxonomists should realize that how their research is related to other related sciences and how they make collaborative works. Especially, the basic taxonomic knowledge and skills generated by taxonomists is more needed to cope with the change of weather, due to the global warming which make critical change of the ecological structure in nature. In the presentation, the strategy for innovation of the living organism on our planet, with a crisis of taxonomy, will be discussed, and emphasized how taxonomists serve and contribute to other related topics. In addition, author will introduce his acitivity for innovation works on Lepidoptera, representing more than 500 new species and 23 new genera of moths described worldwide during last 40 years of his taxonomic research. The total number of new species described in Korea by him is 104 species, including 57 species of Gelechiidae, and more than 400 species and 22 new genera in the subtropical region, including Thailand, Vietnam, and New Guinea. Will it be possible to exceed 500 insect species described worldwide by a taxonomist in future?
