물류 프로세스는 일반적인 비즈니스 프로세스와는 달리, 서로 이질적인 조직이 참여하여 프로세스를 진행한다는 특징을 보인다. 따라서 각 참여조직들 간의 상호작용을 제어하면서 프로세스를 수행하는 것이 필요하다. 프로세스의 실행이라는 측면에서 이를 제어하는 가장 좋은 대안으로 비즈니스 프로세스 관리(BPM) 시스템을 들 수 있으나, 참여조직 간의 프로세스 소유권과 접근 권한 관리 문제와 함께, 현재의 일반적인 상용 시스템들은 참여조직 간의 상호작용을 관리하기 위한 기능을 거의 제공하지 못한다는 문제점을 안고 있다. 또한 RFID 기술 기반의 물류 환경에서, RFID 이벤트의 적용과 처리를 지원하는 물류프로세스 관리에 대한 고려가 미흡한 실정이다. 따라서 본 연구에서는 물류 환경에서 발생하는 다조직 프로세스를 RFID 이벤트 기반의 통제를 위한 새로운 방법론을 제시하고자 한다. Interworkflow(워크플로우 간) 패턴으로 표현되는 참여조직들 간의 프로세스 자동 트리거링(Auto-Triggering)을 위하여 ECA(Event-Condition-Action) 규칙에 복합이벤트(Complex Event)를 활용한 RFID 이벤트 기반의 RFID-based ECA 규칙을 제공한다. In logistic environments, a process, in that it manages the flow of materials among partners, involves more than one organization. In this regard, a logistic process, as a combined process consisting of multiple sub processes, needs to be managed with controling interaction among partners. In achieving systematic management of a logistic process, traditional Business Process Management (BPM) cannot be used for the entire flow, since it lacks the ability to manage interactions among partners. Particularly in logistic environments where RFID technologies are used, how to deal with the connection between RFID event and logistic flow has not been properly addressed. To overcome this limitation, this paper proposes a new method of managing multi-organizational logistic processes based on RFID events. We define inter-workflow pattern, and suggest ECA(Event-Condition-Action) rules for auto triggering of logistic processes. To adjust the rules to RFID events, we invent RFID-based ECA rules using complex event. A prototype system has been developed for the purpose of demonstrating the effectiveness of our approach.

<P>Infection by microorganisms may cause fatally erroneous interpretations in the biologic researches based on cell culture. The contamination by microorganism in the cell culture is quite frequent (5% to 35%). However, current approaches to identify the presence of contamination have many limitations such as high cost of time and labor, and difficulty in interpreting the result. In this paper, we propose a model to predict cell infection, using a microarray technique which gives an overview of the whole genome profile. By analysis of 62 microarray expression profiles under various experimental conditions altering cell type, source of infection and collection time, we discovered 5 marker genes, <I>NM_005298</I>, <I>NM_016408</I>, <I>NM_014588</I>, <I>S76389</I>, and <I>NM_001853</I>. In addition, we discovered two of these genes, <I>S76389</I>, and <I>NM_001853</I>, are involved in a <I>Mycolplasma</I>-specific infection process. We also suggest models to predict the source of infection, cell type or time after infection. We implemented a web based prediction tool in microarray data, named Prediction of Microbial Infection (http://www.snubi.org/software/PMI).</P>

<P>We demonstrate all-solid-state flexible supercapacitors with high physical flexibility, desirable electrochemical properties, and excellent mechanical integrity, which were realized by rationally exploiting unique properties of bacterial nanocellulose, carbon nanotubes, and ionic liquid based polymer gel electrolytes. This deliberate choice and design of main components led to excellent supercapacitor performance such as high tolerance against bending cycles and high capacitance retention over charge/discharge cycles. More specifically, the performance of our supercapacitors was highly retained through 200 bending cycles to a radius of 3 mm. In addition, the supercapacitors showed excellent cyclability with C(sp) (~20 mF/cm(2)) reduction of only <0.5% over 5000 charge/discharge cycles at the current density of 10 A/g. Our demonstration could be an important basis for material design and development of flexible supercapacitors.</P>
