SOA는 하나의 시스템이 아니며 다양한 서비스를 제공하기 위한 다양한 시스템이 SOA개념 하에 서로 유기적으로 연계되어 있다. 이러한 SOA를 실현하는 미들웨어이며, 분산된 서비스 컴포넌트의 효율적인 통합을 실현하는 ESB는 BPEL 혹은 솔루션 벤더의 자체적인 표준을 따르는 프로세스 매니저와 연동해 프로세스 기반의 통합을 지원한다. 기업 차원에서 볼 때, 안정적인 SOA를 기반으로 BPM을 구축하면 BPM이 보다 민첩하고 유연해지며, 여러 부서와 위치에 걸쳐 BPM을 보다 쉽게 확장할 수 있고, 기본 IT 시스템의 변화에 보다 탄력적으로 대응할 수 있다. 또한, 프로세스에 필요한 일부 서비스를 거래 파트너에 아웃소싱할 수 있고, 회사의 고유한 프로세스를 내외부의 신규 고객에게 서비스로 제공할 수 있는 새로운 비즈니스 모델을 만들 수 있다. 이런 비즈니스 프로세스를 운영하면서 서비스에 대한 품질과 각 프로세스에 대한 관리를 효율적으로 하기 위하여 본 논문에서는 EERP (End to End Resource Planning)을 적용하여 QoS를 보장하고자 한다. EERP는 SO(Service Oriented)-SCM이나 SO-CRM과 같은 엔터프라이즈 환경에서의 내부, 외부의 리소스들을 최적화 하며, 프로세싱에 사용되는 각 리소스들을 실시간으로 감시하며 QoS를 보장하는 매커니즘을 통하여 최적화한다. 이를 기반으로 본 논문에서는 이러한 EERP QoS 구조를 제시한다.

The East Sea Branch (ESB) of KORDI will be launched in 2008. She will take a role of monitoring the sea surface topography and temperature by satellites, short- and long-term sea levels by tide gauges, coastal currents and open-sea circulation by setting up coastal radars and mooring current-meters and acoustic equipments, as well as monitoring nearshore processes, coastal erosion and water pollution. A basic program of coastal zone management will help ocean-policy makers to set up right decisions based upon scientific background of the regional data in the East Sea. Networking among the neighboring countries around the sea will supply more useful information not only for experts but also for ordinary vacationers or fishermen. In order for this program to be successfully settled down during the next decade, it is necessary for a leader to have the right vision to attract more experts from global brain pools and to manage the ESB as a leading-edge observatory in the world. Details about this leading-edge operational program are introduced in the text.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced, and the Web services and ESB (Enterprise Service Bus) ate also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which is introduced in this paper, will be a good reference for future SOA implementation.

In order to succeed in today's changing business environment, the enterprise should adapt their process flexible. To increase their business process flexibility they need to establish and end-to-end integration internally as well as among partners. Now that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced And the Web services and ESB (Enterprise Service Bus) are also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which introduced in this paper, will be a good reference for future SOA study.

In this work, we studied a fluorite structure oxides: Yttria stabilized zirconia, (YSZ); Gd doped $CeO_2$ (GDC); erbia stabilized $Bi_2O_3$ (ESB); Zr doped erbia stabilized $Bi_2O_3$ (ZESB); Ca doped erbia stabilized $Bi_2O_3$ (CESB) in the temperature range of 250 to $600^{\circ}C$ using electrochemical impedance spectroscopy (EIS). As is well known, grain boundary blocking effect was observed in YSZ and GDC. However, there is no grain boundary effect on ESB, ZESB, and CESB. The Nyquist plots of these materials exhibit a single arc at low temperature. This means that there is no space charge effect on ${\delta}-Bi_2O_3$. In addition, impedance data were analyzed by using the brick layer model. We indirectly demonstrate that grain boundary ionic conductivity is similar to or even higher than bulk ionic conductivity on cubic bismuth oxide.

국내외적으로 차세대 아키텍처인 SOA에 대한 관심이 높아지고 있으며, 수년 내에 SOA가 일반적인 아키텍처가 될 것으로 전망 되고 있다. 하지만, 여전히 많은 기업들이 막연하게 SOA가 현실화 되기 에는 아직은 많은 위험 요소가 있는 것으로 판단 하고 있다. 본 논문에서는 SOA기반 차세대 Architecture에 대한 시나리오 기반의 정성적, 정량적인 검증을 수행 하여 아키텍처적인 관점에서 타당성을 제시하고, SOA를 실제 구축 프로젝트에 적용하기 위한 방안을 제시하여, 이론 및 사상적인 측면에서 벗어나 현실화된 Architecture로써 SOA가 도입 될 수 있도록 하고자 한다.

An Environmental Specimen Bank (ESB) is an archive for samples that can be used to document and assess the quality of the environment in which we live. An ESB program looks at changes in the concentration of human and environmental specimens over long periods of time through retrospective analysis of archived samples of a particular area collected at regular intervals. The idea of ESB was first proposed by German and American scientists in the early 1970s and has been established since 1979 in Germany, USA, and Japan. Korea plans to establish a National Environmental Specimen Bank (NESB) in 2010. The NESB will be able to assess and improve the quality of analytical measurements as well as to compare the past and current environmental quality as a time capsule. The concept and design for the NESB facility was developed and its Standard Operation Procedures (SOPs) are being developed based on an evaluation of ESBs and SOPs of Germany, USA, and Japan. Environmental specimens proposed for banking are based on typical representatives of every level of the food chain from each type of ecosystem that are widely distributed thus enabling comparisons between different sampling areas. Through retrospective analysis of environmental specimens, the NESB will improve the reliability of environmental monitoring, ecological risk assessment, and health impact assessment.

In this study, we developed real-time urban stream discharge forecasting model using short-term rainfall forecasts data simulated by a regional climate model (RCM). The National Centers for Environmental Prediction (NCEP) Climate Forecasting System (CFS) data was used as a boundary condition for the RCM, namely the Global/Regional Integrated Model System(GRIMs)-Regional Model Program (RMP). In addition, we make ensemble (ESB) forecast with different lead time from 1-day to 3-day and its accuracy was validated through temporal correlation coefficient (TCC). The simulated rainfall is compared to observed data, which are automatic weather stations (AWS) data and Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA 3B43; 3 hourly rainfall with $0.25^{\circ}{\times}0.25^{\circ}$ resolution) data over midland of Korea in July 26-29, 2011. Moreover, we evaluated urban rainfall-runoff relationship using Storm Water Management Model (SWMM). Several statistical measures (e.g., percent error of peak, precent error of volume, and time of peak) are used to validate the rainfall-runoff model's performance. The correlation coefficient (CC) and the Nash-Sutcliffe efficiency (NSE) are evaluated. The result shows that the high correlation was lead time (LT) 33-hour, LT 27-hour, and ESB forecasts, and the NSE shows positive values in LT 33-hour, and ESB forecasts. Through this study, it can be expected to utilizing the real-time urban flood alert using short-term weather forecast.

This study was to investigate characteristics of Seoho watershed in Suwon city. $BOD_5$ and SS were selected due to the one of the important factors of the water qualities. Monitoring was conducted monthly for four years during the non-rainfall time. Also, we have been monitored $BOD_5$, $COD_{Mn}$, SS, TN and TP with two times sampling after the rainfalls. The highest concentrations of $BOD_5$ and SS were observed in downstream compare with upstream and midstream during the non-rainfall time. No change was observed in $BOD_5$ and $COD_{Mn}$ during the non-rainfall time and after the rainfalls. The monitoring result indicated that the concentration of SS was the highest in downstream after the rainfalls. We have collected the samples two times after the rainfalls. The rainfall intensity in first sampling was two times higher than second sampling. TN and TP concentrations were increased with increasing the rainfall intensity at all stream. The ESB (Ecological Score of Benthic macroinverterbrate community) index was used to evaluate the statement of stream. ESB results were identified that the upstream is protected waters and the down and midstream is reformed waters. EBS analysis results indicated that the Seoho watershed was ${\beta}$-mesosaprobic at all stream.

전력시스템의 배전분야 정보모델 및 데이터교환 국제표준인 CIM(Common Information Model, IEC61968) 기반 MDMS(Meter Data Management System, 미터데이터관리시스템) 개발에 있어서, 가장 중점을 두는 부분은 짧은 주기로 수집되는 데이터의 효과적인 관리와 AMI 데이터를 활용하기 위하여 상위시스템들과 어떻게 통합서비스 할 것인가에 대한 이슈이다. 본 논문에서는 기존의 AMR 환경과 다르게 양방향 서비스 인프라를 제공하는 AMI 환경에서 MDMS 구현 방안과 기능들을 제안한다. 본 논문에서 제안하는 MDMS의 특징은 국제전력표준인 CIM과 통합서비스버스(ESB)를 활용하여 상호운영성을 확보했다는 점과 컴포넌트 기반으로 시스템 모듈을 구현하여 현장 활용도 향상이 가능하다는 점이다. 본 연구의 제안된 결과는 지능형전력망 구현에 있어서 CIM 기반 전력시스템의 효율적인 개발 및 운영에 기여할 것으로 기대한다.
