This study examined the influence of the separation of prescribing and dispensing roles(SPD) policy implemented in Korea in July 2000, especially on the change in the net profit of medical institutions. Using the data set from the Korea's National Health Insurance and the previous research, this study elicited the following main results. First, tertiary care institutions was estimated to lose about 631 billion won after the SPD policy. Second, general hospitals and hospitals gained about 557 billion and 564 billion won, respectively. Third, it is shown that clinics also gained 389-659 billion won. Finally, however, the change in net profit of medical institutions after the SPD policy largely depends on different estimation models. Moreover, it also varies from the assumptions on the price differential of a reimbursable drug which worked as cross-subsidy to insufficient physician's fee before the SPD policy. Despite such limitations as lack of data outside of the National Health Insurance's coverage, this study differs from others. This is the first research to explore the effect of the SPD policy on different types of medical institutions and to attempt to purely focus on the SPD policy. In this study, we can draw the policy implication that preparing for a policy change, the government should set up the policy evaluation system to collect the concerned data and develop the methodologies in advance to the policy implementation.

Objective : The objective of this study was to determine a discriminat validity of the Sensory Processing Scale-Children (SPS-C) for children with and without Sensory Processing Disorder (SPD). Method : The SPS-C was completed by parents of 151 Korean children including 68 typically developing children (control group), 83 children with SPD (known group) in the age range 3-5 years, in South Korea. ANCOVA with sex as covariable was used to identified the difference between the children with typically development and SPD. Results : Sensory processing differences in sensory domains and sensory factors were detected and the gender differences were not effective between typically developing children and children with SPD. Significant differences were found in all sensory domain score and total score except proprioceptive processing in sensory domain. In sensory factors, significant differences were found in overrsensitivity, underresponsivity, and discrimination, but sensory seeking was not significant. SPS-C was a valid assessment tool to identify or screen of SPD in Korea. Conclusion : The psychometric characteristics for the standardization study of SPS-C were presented, and the discriminant validity to screen the children with sensory processing problems was presented as a verified evaluation tool. SPS-C will be helpful in screening, analyzing and interpreting characteristics of sensory processing, and establishing an intervention plan.

TCP 프로토콜과 ATM 프로토콜과의 형태 및 제어방식의 차이로 인한 이질성 문제 때문에 ATM 층에서 한 개의 셀 손실은 상위 TCP층에서 하나의 패킷 손실을 초래하게 되어 망에 대한 충분한 QoS를 제공하지 못한다. 이러한 문제들을 해결하기 위해 처리율면에서 Early Packet Discard(EPD)와 공정성면에서 Selective Packet Discard(SPD), Fair Buffer Allocation (FBA) 등이 제안되었다. 본 논문에서는 ATM상에서 TCP 성능성향을 위해 기존의 알고리즘과 제안한 알고리즘에 대하여 비교분석하고 , VC의 수를 가변적으로 변화시켜도 제안한 알고리즘은 SPD나 FBA보다 나은 공정성을 보였고, 처리율면에서는 차이가 없음을 시뮬레이션결과를 통해 나타내었다.

The paper reviews three Split Plot Designs (SPDs) of fixed factors, and those are SPD (RCBD, RCBD), SPD (CRD, RCBD) and SBD (Split Block Design). RCBD (Randomized Complete Block Design) and CRD (Completely Randomized Design) are used to deploy whole plot and sub plot. The models explained in this study are derived from random, crossed and nested models.

The tendency of lightning surge to propagate is a eared variously depend on the power system and subject equipment of protection. However, looking into the subject equipment with the lightning surge, the invasion route of lightning surge can be divided in between the two lines of power, between the power line and the ground, the power line and the PE conductor, between the neutral line and the ground and the like. In addition, in the event of the communication equipment, there exists the route of lightning surge incoming from between the communication lines, the communication line and the ground in addition to the power lines. In this study, the tendency of propagation of lightning surge penetrated on to the subject equipment is analyzed through the empirical experiment in accordance with the ground method by using the independent ground, common ground and bypass arrester ground for safety improvement in power lines.

Recently, the natural environment changes drastically and the frequency of occurrence for lightning has gradually been increased. Such lightning delivers high volume of energy along the power line and communication line to the equipment in use. The high volume of energy arising from the lightning surge develops in fast velocity to destroy the facilities in power source and many other facilities in operation in sequential destruction with vast energy. This paper examines the characteristics of ZnO varistor to prevent from thermal runaway. We carry out performance evaluation of electrical characteristics on ZnO varistor. we will develop ZnO varistor Prevented from thermal explosion using test result of this paper.

The importance of service industries is growing as the portion of the service sector increases fast in the recent decades. This research deals with service prototyping and testing in a service laboratory. While products are generally tested through prototyping in new product development processes, services are difficult to test because of the characteristic of service, intangibility. A service laboratory, named s-Scape, is the experiment environment which has been developed to test services in virtual space for the purpose of analysis and improvement of real-world services such as hospitals and automobile show rooms. In this research, we present a service prototyping tool and language to support service test in the service laboratory. We first analyze key elements of service prototypes, and then design the service prototype diagram (SPD) and the service prototype description language (SPDL). SPD, which is a variant of the service blueprint, is a graphical tool to be used to generate SPDL. SPDL is an executable language of describing a service prototype of a real-world service in extensible markup language (XML) to experiment the service environment in virtual space. SPD reflects the control and interface of virtual reality devices, as well as key elements of service modeling. SPD represents a service process in which service providers and customers interact with each other in a service scape.

Recently military industrial company, utilizing company funded R&D and goverment and industry contracts, has developed ACTS/DACS technology. This technology can be utilized to rapidly steer "smart" bullets, "smart" rounds, tactical missile, cruise missile and kill vehicles for both endo- and exoatmospheric applications. The ACTS/DACS typically consists of a Smart Bus Controller(SCB), a proprietary network firing bus, Smart Pyrotechnic Devices(SPD), rocket motors, and a structure. The SCB communicates with the SPDs over the propretary network firing bus. Each rocket motor contains an SPD which provides rocket motor ignition. Firing energy is stored locally in the SPD so surge currents do not occur in the system as rocket motors are fired. This approach allows multiple, truly simultaneous firings without the need for large, dedicated batteries. Each SPD also functions as a network tranceiver and high reliability fir set all in the space of a single-sided 10 millimeter diameter circuit. The present work develops a new means for igniting explosive materials. The volume of semiconductor bridge (SCB) is over 30 times smaller than a conventional hot wire. We believe that the present work has a potential for development of a new igniter such as smart pyrotechnic device.
