  • 본 논문은 RAID 시스템의 몇 가지 구성에 대해 시뮬레이션을 통해 그 성능을 분석한다. 대용량의 RAID를 구성하기 위해서는 다수의 디스크가 필요한데 반해, 하나의 PCI의 버스에 연결될 수 있는 장치의 개수 제한되어 있어 이 경우 확장 PCI 버스가 필요하다. 본 논문에서는 RAID 시스템의 하드웨어 구조, 특히 각 구성요소를 연결하는 PCI버스의 부하에 초점을 맞춘다. 버스 트랜잭션을 세 가지로 분류하고, 각각의 경우를 분석하고 평가한다. 이 분석으로부터 RAID 시스템의 두 가지 구조에 대해 성능을 계산하고 시뮬레이션 한 결과를 비교한다.

  • In this paper, a design and experiment of PCI Express Core verification Model is described. The model targeting Endpoint core verification is designed by using newly-emerging SystemC which is a system design language based on a new C++ class library and simulation engine. In the verification model, we developed a SystemC Host System model which act as a Root Complex and Device Driver dedicated to the PCI Express Endpoint RTL Core. The test of Host System Model is guided by scenarios which implements and acts point of Device Driver and Root Complex and shows the result of simulation. Also, We present the full structure of verification model and Host model.

  • The research develops the calculation steps of Z sigma level, process capability index(PCI) and process performance index(PPI) applicable to the discrete process in the service industry. The paper presents three following topics used related process indexes according to the precision and accuray in the continuous process. The contents include diverse process indexs for nonconformities by SPC attribute control charts and bias coefficient. The same technique of the nonconformites is also used in the nonconforming units. The practical examples are provided to help easier understanding for users.

  • This study was performed to analyse the economic value of abciximab which is used in PCI to prevent high-risk patients with ischemic complications. The effectiveness of abciximab was extracted from published clinical trials by search-ing CCIS, and the direct medical costs relevant to using abciximab were estimated from the NHI claims database. The results in terms of cost per life-year gained (LYG) and cost per QALY gained showed that abciximab was cost-effective enough to deserve its cost. Social net benefit resulting from abciximab in PCI was estimated to be 60-70 billion Won per year.

  • In this paper, we present a design and experiment of PCI Express core verification model. The model targeting Endpoint core based on Verilog HDL is designed by newly-emerging SystemC, which is a new C++ class library based system design approach. In the verification model, we designed and implemented a SystemC host system model which acted as Root Complex and device driver dedicated to the PCI Express Endpoint RTL core. The verification process is scheduled by scenarios which are implemented in host model. We show that the model is useful especially for verifying the RTL model which has dependencies on system software.

  • Despite recent progresses in nanoparticle-based drug delivery systems, there are still many unsolved limitations. Most of all, a major obstacle in current nanoparticle-based drug carrier is the lack of sufficient drug delivery into target cells due to various biological barriers, such as: extracellular matrix, endolysosomal barrier, and drug-resistance associated proteins. To circumvent these limitations, several research groups have utilized photochemical internalization (PCI), an extension of photodynamic therapy (PDT), in design of innovative and efficient nano-carriers drug delivery. This review presents an overview of a recent research on utilization of PCI in various fields including: anti-cancer therapy, protein delivery, and tissue engineering.

  • The purpose of this study was to investigate the effects of clinical characteristics of chronic stroke patients on physiological cost index (PCI) during walking. Fourteen stroke patients participated in this study. To investigate the clinical characteristics, Fugl-Meyer score (FMS), gait velocity (GV), muscle strength of the knee extensor, modified Ashworth scale (MAS) of ankle plantar flexor, devices, and gait patterns during walking were measured and analyzed. The results were as follows: Firstly, use of devices and high MAS of the ankle plantar flexor significantly increased PCI. Secondly, PCI was significantly correlated with the FMS and MAS of the ankle plantar flexor. In conclusion, inhibition of spasticity of the ankle plantar flexor is considered to reduce PCI during walking for chronic stroke patients.
