  • SaaS provides software hosted on the cloud computing in a form of service. Thus, it enables the extension of service functions by combining or reusing the existing software. As an analysis technique, this paper suggests a method of verifying the reusability of a process by analyzing it with the process algebra. The suggested method can confirm the reusability of existing software, ensure the consistency of modifications by tenants or requests, and provide probabilities of combining processes.

  • 대규모 개발사업을 시행함에 있어 우리는 종종 무의식적으로 토양층을 교란시키게 된다. 식물 성장에 있어 토양은 영양분을 공급하는 중요한 역할을 하고 특히 토양 중 표토층은 식물 생장에 필요한 많은 영양성분을 갖고 있으므로 토양층의 파괴는 식재된 수목의 하자와 직접 연결된다. 살아있는 식물을 다루는 조경공사에서는 공사 후 높은 하자율을 걱정하기에 앞서 수목의 원활한 활착을 위해 토양을 건강하게 유지하도록 노력해야 한다. 본 연구에서는 수목과 토양의 생리학적 관계 및 토양의 기본적인 성질과 표토의 중요성, 표토의 특성을 유지하는 방안 등에 대해 고찰하고 사례연구로 한국토지공사에서 시행한 용인 동백지구의 표토 활용사례를 검토하여 문제점을 파악하고 보다 효과적인 표토층 보존을 위한 방향을 제시하고자 한다. 수목의 성장률, 건강도, 수형 등은 직접적으로 토양의 질과 연결되고 양질의 토양은 수목의 원활한 생장을 가져와 결국 수준 높은 경관을 형성할 수 있게 된다. 본 연구를 통해 수목과 토양의 생리학적 관계를 파악하고 수목의 성장에 적정한 환경을 제공함으로써 불량한 토양으로 인한 수목의 하자율을 사전에 방지하고 수목의 건강성을 유지하는 방안 설정에 도움이 되고자 한다.

  • Modern telecommunications are increasingly demanding the addition of complex switching features to switching system software. These improvements also should satisfy customer demands for quick provisioning of new service features. But whenever we have developed the switching system in various types, we met problems that are lack of system engineers and short developments terms. We need new guidelines of software design to meet the demands and overcome our problems. So we propose new software platform, scenario driven call control engine (SDCCE) for ATM switching system software and implement an effective call control software using scenarios for ATM Switching System. A scenario is a set of procedures and supplementary scenarios written in data structure and gives benefits to easy adapt new or modified function by adding a scenario. The goal of SDCCE is to increase reusability and readability of software. Especially, it gives a good software extensibility and maintainability. And when we developed ptmp call processing control software, we could get high productivity by reusing scenarios and procedures of ptp call processing control software. We applied the scenario driven call control software to ATM switching system.

  • This paper presents a top-down approach to implement an MPEG-2 audio encoder in VLSI. As the algorithm of an MPEG-2 audio encoder is heavy-weighted and heterogeneous(to be mixture of several strategies), the encoder design process is undertaken carefully from the algorithmic level to the architectural level. Firstly, the encoding algorithm is analyzed and divided into sub-algorithms, called tasks, and the tasks are partitioned in the way of reusing the same designs. Secondly, the partitioned tasks are scheduled and synthesized to make the most efficient use of time and space. In the end, a real-time 5 channel MPEG-2 audio encoder is designed which is a heterogeneous multiprocessor system; two hardwired logic blocks and one specialized DSP processor.

  • This experimental study was to determine the fitness in each cervical margin of reusing porcelain gold alloy. The gold alloy used in this experimental study was a Au-Pt-Pd alloy (BDCG-898, Bukwang Inc, Korea) for the fabrication of porcelain fused to metal crown. Twenty-five copings were divided into the five groups. And the group A, B, C, D and E were cording successively according to the frequency of reuse to five times. Each specimen was reused without adding new metal. The experimental results were as follows: 1. The group A, B, C showed good fitness in each cervical margin. 2. The group D got good fitness in labio and linguo cervical margin, but the mesio and disto cervical margin showed more than $40{\mu}m$ 3. The group E showed worse fitness than the other groups in each cervical margin.

  • Network-on-chip (NoC) has evolved to overcome the issues of traditional bus-based on-chip interconnect. In NoC-reuse as TAM, the test schedulers are constrained with the topological position of cores and test access points, which may negatively affect the test time. This paper presents a scalable hybrid test data transportation scheme that allows to simultaneously test multiple heterogeneous cores of NoC-based SoCs, while reusing NoC as TAM. In the proposed test scheme, single test stimuli set of multiple CUTs is embedded into each flit of the test stimuli packets and those packets are multicast to the targeted CUTs. However, the test response packets of each CUT are unicast towards the tester. To reduce network load, a flit is filled with maximum possible test response sets before unicasting towards the tester. With the aid of Verilog and analytical simulations, the proposed scheme is proved effective and the results are compared with some recent techniques.

  • Aspergillus sojae B-l0 was immobilized and used to treat model dye compounds. The model wastewater, containing 10 ppm of azo dyes such as Amaranth, Sudan III, and Congo Red, was treated with cells attached to a rotating disc contactor (RDC). Amaranth was decolorized more easily than were Sudan III and Congo Red. Decolorization of Amaranth began within a day, and the dye was completely decolorized within 5 days of incubation. Both Sudan III and Congo Red were almost completely decolorized after 5 days of incubation. Semicontinuous decolorization of azo by reusing attached mycelia resulted in almost complete decolorization in 20 days. This experiment indicated that decolorization was successfully conducted by removing azo dyes with Aspergillus sojae B-10.

  • 건조는 열풍, 스팀 및 전자기파 등의 직접 또는 간접적인 에너지를 투입하여 최종 제품, 가공, 후처리 과정에서 수분을 제거하는 필수 단위공정으로서 화공, 섬유, 식품, 제지·목재, 금속부품 및 폐기물 등에 이르기까지 모든 산업의 생산과정에서 널리 사용되고 있다. 건조공정은 국내 총에너지소비량의 1.2%('95년기준 1,413천TOE), 산업부문 에너지소비량의 2.2%를 소비하는 에너지다소비 장치의 하나이다. 실제론 산업분야 건조설비 사용업체의 에너지사용 비중 중에서 건조공정의 에너지사용 비중이 30%를 초과하고 있으나, 대부분의 건조공정의 에너지 이용효율이 50%이하로서 매우 낮은 실정이다.(중략)

  • In this paper, we classify web-based social network into two types: open and community, and model user behavior in social activities. After that, we also propose the combination of instant messaging and web system as the method of support asynchronous/synchronous social activities. Furthermore, we introduce ImCoWeb prototype system that supports both asynchronous social activities (ex. social bookmark, comment, rate, and data share) and synchronous ones (ex. real-time communication, file transfer, co-browsing, and co-work). Because it is built on the existing instant messaging, it reduces costs by reusing the facilities such as session management, user management, and security of instant messaging.

  • 자막은 청각장애인들의 의사 소통, 정보 전달 및 정보 획득에 중요한 부분을 차지하는 서비스이다. 특히, 지상파 DTV 에서 청각장애인의 방송시청권보장을 위한 일환으로 제공되고 있는 폐쇄자막은 지상파 DTV 뿐만 아니라, 케이블, 위성방송, IPTV 및 VOD 서비스에서도 활용이 가능한 재활용성이 높은 콘텐츠이다. 그러나, 속기사에 의한 실시간 폐쇄자막 서비스가 제공되는 방송환경에서 많은 방송 프로그램의 폐쇄자막들이 일회성으로 사용되고 사라지는 경우가 많다. 본 논문에서는 이러한 폐쇄자막 콘텐츠의 미디어 매체별 재활용성을 높이기 위한 한 방법으로 CEA-708 표준을 지원하는 폐쇄자막의 사전 제작 및 기저작된 자막의 편집을 위한 저작도구를 소개한다.
