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.

This study presents the direction of data triggers and elements to be recorded in automated vehicles in the future in relation to the event data recorder (EDR) and data storage system for automated driving (DSSAD). It does not distinguish between the EDR and DSSAD, but suggests data triggers and elements in preparation for overall automated vehicle accidents and dangerous situations. To propose, the current status of discussions on EDR/DSSAD internationally and the case of investigating accidents with automated vehicles under temporary driving licenses in Korea were analyzed. Based on the analysis, the direction of data triggers and elements of the EDR/DSSAD of automated vehicles were presented.

This paper presents a new approach for the detection of seismic events using accumulated changes on time-frequency domain and variable threshold. To detect seismic P-wave arrivals with rapidness and accuracy, it is that the changes on the time and the frequency domains are simultaneously used. Their changes are parameters appropriated to reflect characteristics of earthquakes over moderate magnitude(${\geq}$ magnitude 4.0) and microearthquakes. In addition, adaptively controlled threshold values can prevent false P-wave detections due to low SNR. We tested our method on real earthquakes those have various magnitudes. The proposed algorithm gives a good detection performance and it is also comparable to STA/LTA algorithm in computational complexity. Computer simulation results shows that the proposed algorithm is superior to the conventional popular algorithm (STA/LTA) in the seismic P-wave detection.

Molecular mimicry is an attractive mechanism for triggering autoimmunity. In this review, we explore the potential role of evolutionary conserved bacterial proteins in the production of autoantibodies with focus on granulomatosis with polyangiitis (GPA) and rheumatoid arthritis (RA). Seven autoantigens characterized in GPA and RA were BLASTed against a bacterial protein database. Of the seven autoantigens, proteinase 3, type II collagen, binding immunoglobulin protein, glucose-6-phosphate isomerase, ${\alpha}$-enolase, and heterogeneous nuclear ribonuclear protein have well-conserved bacterial orthologs. Importantly, those bacterial orthologs are also found in human-associated bacteria. The wide distribution of the highly conserved stress proteins or enzymes among the members of the normal flora and common infectious microorganisms raises a new question on how cross-reactive autoantibodies are not produced during the immune response to these bacteria in most healthy people. Understanding the mechanisms that deselect auto-reactive B cell clones during the germinal center reaction to homologous foreign antigens may provide a novel strategy to treat autoimmune diseases.

The purpose of this study is to find the causes of malfunctions and defective operation of printed circuit boards(PCBs) built into home refrigerators to perform power saving functions. This study performed an electrostatic test of a PCB built-in using an Auto Triggering system; lightning and impulse tests using an LSS-15AX; and an impulse test using an INS-400AX. From the analysis of a secondarily developed product, it was found that electrostatic discharge(ESD) caused more malfunctions and defective operations than electric overstress(EOS) due to overvoltage. As a result of increasing the condenser capacity of the PCB circuit, withstanding voltage was increased to 7.4 kV. In addition, this study changed the power saving mode and connected a varistor to the #2 pin of an IC chip. As a result, the system consisting of all specimens of a finally developed product was operated stably with an applied voltage of less than 10 kV. This study found it necessary to perform quality control at the manufacturing stage in order to reduce the occurrence of electrostatic accidents to IC chips built into a PCB.

This experiment is carried out for test whether the addition temperament drugs of Danchisoyo-san have an anti-inflammatory effect and have suppression effect on immunocyte in the state of inflammation which induced by carageenan and zymosan. The freezing lyophilization powder which were extracted from Danchisoyo-san divided low dose group(200mg/kg-DSL) and high dose group(500mg/kg-DSH) and after melting in water, it was orally administered to the mouse. Compared with inflammation induced group which were induced by triggering-inflammation reagent carageenan and zymosan and normal contrast group, we measured the edema decrement effect, macrophage and spleen cell activation. 1. Danchisoyo-san has suppress inflammatory reaction induced by carrageenan. 2. Danchisoyo-san has suppress increasing activation of abdominal cavity macrophage cell in the carrageenan induced inflammation. 3. Danchisoyo-san has suppress increasing activation of spleen cell in the carrageenan induced inflammation. 4. Danchisoyo-san has suppress increasing activation of abdominal cavity macrophage in the zymosan induced inflammation. 5. Danchisoyo-san has suppress increasing activation of spleen cell in the zymosan induced inflammation. Based on the above result, Danchisoyo-san was improved its suppression effect to the inflammatory reaction through the suppression of spleen cell and macrophage activation. So we concluded that Danchisoyo-san is prospected as a anti-inflammatory agent to cure inflammation.

Type I diabetes, also known as insulin-dependent diabetes mellitus (IDDM) results from the destruction of insulin-producing pancreatic $\beta$ cells by a progressive $\beta$ cell-specific autoimmune process. The pathogenesis of autoimmune IDDM has been extensively studied for the past two decades using animal models such as the non-obese diabetic (NOD) mouse and the Bio-Breeding (BB) rat. However, the initial events that trigger the immune responses leading to the selective destruction of the $\beta$ cells are poorly understood. It is thought that $\beta$ cell auto-antigens are involved in the triggering of $\beta$ cell-specific autoimmunity. Among a dozen putative $\beta$ cell autoantigens, glutamic acid decarboxylase (GAD) has bee proposed as perhaps the strongest candidate in both humans and the NOD mouse. In the NOD mouse, GAD, as compared with other $\beta$ cell autoantigens, provokes the earliest T cell proliferative response. The suppression of GAD expression in the $\beta$ cells results in the prevention of autoimmune diabetes in NOD mice. In addition, the major populations of cells infiltrating the iselts during the early stage of insulitis in BB rats and NOD mice are macrophages and dendritic cells. The inactivation of macrophages in NOD mice results in the prevention of T cell mediated autoimmune diabetes. Macrophages are primary contributors to the creation of the immune environment conducive to the development and activation of $\beta$cell-specific Th1-type CD4+ T cells and CD8+ cytotoxic T cells that cause autoimmune diabetes in NOD mice. CD4+ and CD8+ T cells are both believed to be important for the destruction of $\beta$ cells. These cells, as final effectors, can kill the insulin-producing $\beta$ cells by the induction of apoptosis. In addition, CD8+ cytotoxic T cells release granzyme and cytolysin (perforin), which are also toxic to $\beta$ cells. In this way, macrophages, CD4+ T cells and CD8+ T cells act synergistically to kill the $\beta$ cells in conjunction with $\beta$ cell autoantigens and MHC class I and II antigens, resulting in the onset of autoimmune type I diabetes.
