The management and deposit of paper document costs are increased gradually. Specially, it is too expensive to safekeeping paper document in the warehouse. Also paper based document system is exposed in several security problems. Therefore, demands of transformation process from paper document into electronic ones are quietly needed. Electronic document repository system is one of the best solutions for solving paper based document system issues. Electronic document repository system can reduce overall costs and provides some advantages in comparison with paper based document system. But, electronic document repository system has no formal methodology for guarantee safeties. Therefore, we suggest a security mechanism for establish electronic document repository system. Suggested security methodology can help for design of more secure electronic document repository system.

모든 가축사양에 있어 물은 매우 중요하다. 하지만 그보다도 더욱 결정적인 것은 사료이므로 매우 주의해 관리해야 한다. 그러므로 사료는 일정기간 동안 사료의 품질을 유지할 수 있는 적정한 시설에 보관하는 것 역시 매우 중요하다. 모든 농장에서 사료를 적절히 보관하는 것은 필수적인 관리 항목이다. 불량한 상태의 시설에 사료를 보관하면 품질이 떨어지기 때문이다. 이는 결국 사육하는 가축의 성장을 늦추고 영양균형을 깨뜨리면서 건강상의 문제가 발생하고 높은 폐사율로 이어질 수밖에 없다.

The microbial contamination rate of contact lens cases in multi-purpose solution(MPS) care systems of 80 asymptomatic soft contact lens wearers was investigated. In caring for their lenses 72 patients (90%) used chemical disinfection(include MPS), six patients(7%) used hydrogen peroxide, and two patients(3%) used heat. Fifty-nine percent of patients used MPS in their care systems. Of 80 contact lens cases, contamination was found in 68%(54) of cases. There is a significant relationship between the ages of lens cases and contamination: older cases being more frequently contaminated. Of the contaminated 31 lens cases(57%) in MPS care systems, four contact lens cases(13%) were contaminated by single organism, 15 cases(48%) by two kinds of organisms, and 12 cases(39%) by more than three kinds of organisms. Of the organisms that were contaminated lens cases, Pseudomonas. Serratia, Bacillus, E. coli and Aspergillus were frequently isolated. When considering the high contamination rate of soft contact lens cases in MPS care systems more effective and hygienical lens care system is important, especially frequent and regular disposal of lens cases may prove to prevent the build-up of microbial colonisation in containers.

대부분의 도면은 종이나 천 또는 마일라(Mylar, 주:강화 폴리에스테르 필름, 세피아 라고도 부름) 등에 저장하거나, 현대에 와서는 디지탈 방식으로 컴퓨터에 저장한다. 그러나 최근에 와서는 광학적으로 저장하는 제3의 방법이 등장하였다. 도면과 지도를 콤팩트디스크에 광학적으로 보관하면 종이나 천 등에 보관할 때보다 더 오래 보존되고 더 쉽게 관리할 수 있을 뿐만 아니라, 전 시스템을 전산화 시킨 도면관리방식에 비해 훨씬 낮은 비용으로 저장과 관리가 가능해진다.

사료공장에서 생산한 사료를 휘드빈에 보관하게 되는데 자칫 보관이 소홀하면 변패한 사료급여로 경영적 손실을 초래한다. 중요하면서도 소홀히 다루고 있는 Bin의 위생관리 요령을 체크해본다.

Purpose: This study was conducted to investigate the actual condition of caring soft contact lens cases and the change in contamination level of lens cases by wearing and storage period of soft contact lens. Methods: The actual condition of caring soft lens cases was surveyed with sixty-three of contact lens wearers. Soft contact lenses were worn for 1, 3, 7 and 14 days, and the lenses were separately stored in 12 lens cases for 1, 3 and 7 days. The contamination level of lens cases was determined by counting the numbers of microorganisms, gram negative bacteria and fungi. Results: Only 14% of survey answerers cleaned their lens cases with a brush, rinsed and dried them upside down before next usage of lens case when those lenses were kept for a long time. Furthermore, 54% of total answerers just kept soft contact lens in the case without changing the multipurpose solution. Microorganisms, gram negative bacteria and fungi were detected in lens cases even when soft contact lens were kept for 1 day in the lens case after wearing for 1 day and cleaning it with multipurpose solution. The numbers of microorganisms, gram negative bacteria and fungi in lens cases increased with storage periods of soft contact lens, and also contamination level of lens cases was increased in accordance with wearing period of lens. In the lens cases without changing multipurpose solution, the numbers of microorganisms, gram negative bacteria and fungi increased with storage period of lens with statistical significance. Conclusions: This study showed that lens wearers' concerns on caring contact lens case were not satisfactory. As the result, the contamination of lens cases was related to increase of lens wearing and storage periods suggesting that the proper instruction and education for lens wearers are required.

CeDA (Certified e-Document Authority) was adopted in March 2005. It is possible to register/store/send/receive/transfer/revoke e-documents by using trusted third party, CeDA. It is important to store not only e-documents of users but also logs produced by CeDA. Thus all logs must be electronically signed using certificate of CeDA. But management of electronically signed logs is difficult. In this paper, the method which can be applicable to authenticate all logs of CeDA using "Hash Tree" is present.

CMS(Contents Management Solution)는 컨텐츠를 관리하는 시스템을 의미. 시장조사기관 Ovum은 CMS에 대하여 'e-Business에 포함되는 모든 컨텐츠를 생성, 보관, 관리하는 일련의 작업(Task)과 과정(Process)'이라고 정의. 일반적으로는 '기업 내에 존재하는 다양한 포맷의 컨텐츠인 문서, 이미지, 동영상, 소리 등을 제작, 출판, 관리하는 솔루션으로 보통 컨텐츠 생성, 출판, 배포, 보관 등으로 정리되는 컨텐츠 라이프스타일 전체를 관리하는 것'으로 규정. (중략)

여름철에 사료를 보관시 고온다습한 환경을 피하고 공기가 잘 통하게 하고, 사료를 보관하는 바닥에는 반드시 나무판이나 처란을 깔아야 한다. 또한 생산일자별로 사료를 관리하여 오래된 사료부터 먼저 급여하도록 한다.
