Software release over the network is the most efficacious way of software update. Software release of electronic switching system, considering its environments, is the typical case that is in need of adopting the method. The media of transferring software and data of TDX-10A electronic switching system are magnetic tapes containing them, so the MT must be delivered between remotely placed office and package generation system. SMART-10A system provides the file tranfer on the data network between TDX-10A and the package generation system and ability of remote application of new software. This paper shows the implementation of file transfer between TDX-10A and computer system connected by data networks, status handling for duplicated system, and monitor process design with IPC on UNIX system.

오늘날 클라우드 서버 시스템 환경은 급속도로 증가하는 데이터를 효율적으로 처리 및 저장하기 위해 네트워크로 연결된 다수의 서버 머신들로 clustering 이나 분산 시스템 환경, 또는 SAN(Storage Area Network) 환경 등을 구성하여 보다 효율적인 서버시스템을 구현하고 있다. 이러한 서버시스템 환경에서의 병목현상은 주로 디스크기반의 스토리지에서 발생하며, 이를 극복하기 위해 고성능 스토리지에 대한 요구가 증가하고 있다. 그러나, 단순히 디바이스를 교체하는 것 만으로는 고성능 장비의 뛰어난 성능을 제대로 활용할 수 없으며 그에 맞는 최적화 작업이 요구된다. 본 논문에서는 기존의 SAN Solution 의 문제를 분석하고, 고성능 스토리지의 성능을 잘 활용할 수 있는 설정 및 최적화 방법을 제안한다.

To examine toddlers’adjustment in child care centers according to the quality of child care environment, the followings were asked; 1. Are toddlers’adjustment in child care centers different by toddlers’individual characterisitcs, caregiyer’s individual characteristics, and/or care center variabless\ulcorner 2. Are the quality of child care center different by caregiver’s individual characteristics and child care center variables\ulcorner 3. Are toddlers’adjustment in child care centers different according to the quality of child care center\ulcorner Forty caregivers and 108 toddlers in 40 child care centers in Inchon were randomly selected. After 2 hours of observation in each child care center, the quality of child care environment were rated using Infant/Toddler Environment Rating Scate(ITERS) by 2 observers and toddlers’adjustment in child care centers were rated by caregivers using the Preschool Adjustment Questionnaire(PAQ). Toddlers’adjustment in centers were different by toddlers’gender, caregiver’s age, caregiver’s educational level, group size, and the adult/child ratio. The quality of child care environment of child care centers was different by caregiver’s age, caregiver’s career level, the length of working time, group size, and the adult/child ratio. Finally, toddler’s adjustment in child care centers were significantly different by the quality of child care environment of child care centers.

Rural multi-purpose buildings needs to ensure their safety against various disasters. Therefore, a pile foundation, which is a foundation type that can transmit the load of the structure to the bedrock layer, has been designed. The pile foundation method is largely divided into driving piles method and pre-bored pile method. Recently, in order to respond to the Noise and Vibration Control Act and related environmental complaints, construction of pile foundation adopts pre-bored pile method. The bearing capacity of the pre-bored pile method is calculated through a load test in situ. However, a disadvantage stems in that it is difficult to measure the ultimate bearing capacity due to field conditions. Therefore, in this study, the skin frictional force of pre-bored pile was measured through a model test in laboratory for each pile filling material. In result, the pile filling material with using circulating resources shows superior skin frictional force than ordinary portland cement. This study also judged that the result can be applied in place of ordinary Portland cement in the field.

Objective : In order to compare of hyperlipidemia effect of C. wilfordii, C. auriculatum in korea and C. auriculatum in China, it was performed on the hyperlipidemia in rats induced by Triton WR-1339. Method : The 70% MeOH extracts from dried root of C. wilfordii and C. auriculatum in korea and C. auriculatum in china were fractionated into H2O layer and CHCl3 layer. The level of total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, AST and ALT in serum were used to observe the effectiveness of C. wilfordii korean C. auriculatum and chinese C. auriculatum. Results : In the hyperlipidemic rats induced by Triton WR-1339, C. wilfordii and korean C. auriculatum significantly decreased total cholesterol, triglyceride, otherwise significantly increased HDL. And C. wilfordii and chinese C. auriculatum significantly decreased AST and ALT. Conclusion : This study indicate that C. wilfordii korean C. auriculatum and chinese C. auriculatum were effective in the hyperlipidemic rats induced by Triton WR-1339. According to the results, C. wilfordii korean C. auriculatum and chinese C. auriculatum need to considered for the application in hyperlipidemia.
