클라우드 서비스 공급자가 제공하는 클라우드 스토리지 시스템은 대량의 데이터 저장 및 클라우드 컴퓨팅 처리의 핵심구성요소이다. 구글, 유투브, 페이스북 등과 같은 대형 벤더에서도 클라우드 스토리지를 사용하여 태블릿, 스마트폰 등 이기종 장치에서 사진, 동영상, 문서등을 공유하며, 쉽고 빠르게 네트워크를 통해 데이터의 대량 전송과 접근이 가능하다. 이로 인해 전세계적으로 데이터 성장 발전과 함께 클라우드 스토리지가 비지니스모델로 새롭게 부각받고 있다. 클라우드 스토리지는 네트워크 스토리지의 새로운 서비스 개념이며 데이터 구성, 스토리지 가상화, 데이터 복제와 중복제거, 보안 등을 포함한 클라우드 컴퓨팅 핵심기술이다. 본 논문에서는 클라우드 스토리지에 대해 분석한다.

This Study is to develop the suitable hydrologic models for determination of the size and location of detention storage facilities to restrain stormwater runoff in urban areas. Hypothetical areas of two levels are considered to seize the hydrologic response characteristics. A one-square-kilometer ares is selected for the catchment level, and a 10-square-kilometer area consisting of 10 catchments is adapted at the watershed level as representative of urban drainage area. In this analysis, different rainfall freqyencies, land uses, drainage patte군, basin shates and detention storage policies are considered. Folw reduction effect of detention storage facilities is deduced from storage ratio and detention basin factor. A substantial saving in detention storage volumes is achieved 노두 the detention storage is planned at the watershed level rather than the catchment level. For the application of real watersheds, two watersheds in Seoul metropolitan area-Jamshil 2 and Seongnae 1-are selected on the basis of hydrologic response charactaristics. Through the regression analysis between dimensionless deterntion storage volume, dimensionless upstream area ratio and reduction rate of storage ratio, the regression equations to determine the size and location of detention storage faclities are presented.

The changes of the color, texture and volatile flavor compounds of Yu-gwa were investigated that affected by the oxidation during storage to characteristic Yu-gwa quality. Among the proximate compositions, carbohydrate was the most abundant component, and followed by lipid and moisture. Although the change of the color showed different pattern by the packaging materials during the storage period, the value of yellowness(b) increased but that of lightness(L) decreased dramatically after 3 month storage. In the textural properties reported closely related with the moisture content, hardness was fairly affected on the period of the storage rather than the type of packaging materials. The flavor compounds of Yu-gwa were analyzed to evaluate the change of distinct volatile compounds during storage. Of the twenty one separated volatile compounds, major volatiles were aldehydes, alcohols and alkenes. The results also showed that polyethylene(PE) contained less volatiles than polypropylene(PP) by the oxidation process during storage.2,4-Decadienal was gradually increased with the period of the storage, whereas octane and furan were decreased. The results provided that the change of the flavor distribution during the storage, and also the possibility of the volatiles such as hexanal, nonanal and 2,4-decadienal as the indicator for the oxidation process.

This paper aims to reduce the frequency of dangerous goods storage accidents in China. Advocating the managers of warehousing and logistics enterprises to pay attention to the operation process of dangerous goods warehousing business. Improving the safe storage and management capabilities of dangerous goods warehouses. This article first collects official data on dangerous goods storage accidents in China and conducts a general statistical analysis of the accidents. Based on the results of accident statistics and related literature research on dangerous goods storage management, establish a dangerous goods storage safety management factor system, use the analytic hierarchy process, establish a factor importance questionnaire and implement data collection. Through statistics, this paper finds that the storage accidents of dangerous goods in China in the past ten years mainly occurred in the inbound phase of dangerous goods and the storage phase of dangerous goods warehouses. Through the results of the analytic hierarchy process, it is found that the professionalism of the dangerous goods storage practitioners, the compliance of the practitioners with safety regulations, and the awareness of operational safety are the most important.

본 연구는 에틸렌 처리와 저장조건에 따른 '오텀센스' 다래의 저장성과 품질 변화를 조사하기 위하여 수행하였다. 다래의 저장 중 품질변화를 관찰한 결과, 48시간과 96시간동안 에틸렌을 처리한 모든 처리구에서 경도는 저장기간이 경과함에 따라 급격히 감소하였으나, 당도는 급격히 증가하였다. 산도는 모든 처리구에서 0.7~1.4%수준으로 나타났다. 저장기간 동안 다래의 중량감소율을 조사한 결과, 48시간동안 에틸렌을 처리하고 저장한 다래는 저장 24일 동안 $20^{\circ}C$저장구에서 30.9%로 가장 높았으며, $2^{\circ}C$에 상대습도 90%저장구에서 5.9%로 가장 낮게 나타났다. 96시간동안 에틸렌을 처리하고 저장한 다래는 저장 22일 동안 $20^{\circ}C$저장구에서 29.4%, $4^{\circ}C$저장구에서 20.7%, $2^{\circ}C$저장구에서 12.1% 그리고 $2^{\circ}C$에 상대습도 90%저장구에서 6.0% 감소하였다. 저장기간 동안 다래의 식미는 모든 처리구에서 증가하다 감소하였다. 특히 $20^{\circ}C$저장구는 저장 초기에 급격히 증가하다 감소하였고, $2^{\circ}C$에 상대습도 90%저장구는 저장 18일 후에 감소하였다. 부패율은 모든 처리구에서 저장기간 동안 증가하였으며, $20^{\circ}C$저장구는 저장 2일 후, $2^{\circ}C$에 상대습도 90%저장구는 16일부터 급격히 증가하였다. 따라서, $2^{\circ}C$에 상대습도 90%의 저장조건이 다래의 품질을 유지하는데 효과적일 것으로 판단되며, '오텀센스' 다래의 적정 저장조건과 후숙시기를 판단할 수 있을 것이라 생각된다.

the purpose of this study is to estimate the storage deficit by Run's Characteristics of (-)Run-length and (-)Run-sum. Runoff data are obtained from the guaging stations of Y대-Ju in Hanriver Basin, Wae-Gwan in Nak Dong River Basin and Gyo Am in Geum River Basin. In order to estimate the storage deficit, runhydrographs are established with each return period of 10, 30, ......, 200 years and regression equation is derived from relationship between (-) run-length and storage deficit. From the comparison of estimated reservoir storage with observed values., it was proved that this suggested method can be used for the estimation of the storage deficit.

This paper examines the effect of storage location configurations on dual command cycle times for the efficient operation of automated storage/retrieval systems. We use a contour line approach to determine storage location configurations. We present a contour line configuration generating scheme and a location indexing scheme. Given a contour line configuration, the location indexing scheme provides a unique priority to each location. The location priority is then used for determining the storage location of an incoming load. To investigate the effect of alternative contour line configurations on dual command cycle times, we perform a series of experiments under various storage policies.
