This paper is an exploratory study on the success factors of Defence Quality Management System (DQMS) which is the certification system granted by the military for improving the quality of munitions. DQMS is established by adding military requirements to the ISO standard, thus, we especially focus on the additional requirements to figure out success key factors of DQMS certification. The 51 additional requirements of Korean Defense Specification (KDS) are empirically investigated from 67 companies that acquired DQMS certification. Firstly, we conduct an independent t-tests on 51 additional requirements of KDS 0050-900-3 to determine if there is a difference between an easily certified company and a hard-to-certify company, and obtain 8 requirements such as ‘Internal propagation of performance’, ‘Preparation of documented work instructions’, ‘Work instructions in the workplace’, ‘Documentation of equipment management’, ‘Inventory management’, ‘Packaging and identification’, ‘Guarantee of access to internal audit result for customers’, ‘Notification to the customer for improper product.’ Secondly, we carry out an factor analysis to the 51 additional requirements for classification, and figure out that 4 requirements among the 8 requirements above mentioned are grouped together in the same factor. The 4 requirements are ‘Preparation of documented work instructions’, ‘Work instructions in the workplace’, ‘Packaging and identification’, and ‘Guarantee of access to internal audit result for customers.’ The result of this paper will provide useful information to the company preparing for DQMS.

경피경간담즙배액술은 담석, 양성협착, 악성종양 등에 의한 폐쇄성 황달을 감압시키기 위한 방사선학적 방법이다. 담관을 통한 담즙의 내부배액이 회복되면 경피경간담즙배액 도관은 경피적으로 제거할 수 있다. 본례에서는 병상에서 경피경간담즙배액 도관을 제거할 때, 도관이 복강으로 이동하여 복막염이 발생하였고 경구내시경으로 도관을 제거하였다. 경피경간담즙배액 도관을 제거할 때는 도관이 복강으로 이동하지 않도록 주의하여야 하며, 부주의로 인하여 도관이 복강으로 이동하였을 경우에는 경구내시경으로 도관을 제거할 후 있다.

Insects or insect remains found in beer are one of major issues in consumer claim. Accurate estimation of inflow time isa critical factor for the settlement of such claims related with beer-contaminating insects but no reliable methods have been developed. In an attempt to establish a molecular marker-based diagnostic method, the degradation rates of 18S rRNA genes in the insectssoaked in 500 ml beer were investigated by quantitative real-time PCR (qPCR) over one month period at room temperature. Among the six insect species tested, the house fly (Musca domestica) and honey bee (Apis mellifera) revealed high correlations (r2=0.974-0.990) between the degradation of 18S rRNA gene and inflow time. In these insects, statistically significant distinction was possible between the samples stored in beer less than 14 days and more than 14 days. Other insects, including the fruit fly, common house mosquito, German cockroach and Indian meal moth, displayed poor correlations, which appeared attributed to the inefficient genomic DNA extraction likely due to small sample size or disintegration of body parts during storage in beer. With proper improvement in DNA extraction, this 18S rRNA-based diagnostic method would be applicable for estimating the inflow time of beer-contaminating insects.
