  • Implementing conventional DFT solution for arrays of DNN accelerators having large number of processing elements (PEs), without considering architectural characteristics of PEs may incur overwhelming test overheads. Recent DFT based techniques have utilized the homogeneity and dataflow of arrays at PE-level and Core-level for obtaining reduction in; test pattern volume, test time, test power and ATPG runtime. This paper reviews these contemporary test solutions for ASIC based DNN accelerators. Mainly, the proposed test architectures, pattern application method with their objectives are reviewed. It is observed that exploitation of architectural characteristic such as homogeneity and dataflow of PEs/ arrays results in reduced test overheads.

  • The toxic responses of flagellate Euglena agilis Carter to 8 heavy metals (Ag, Cd, Cr (VI), Cu, Hg, Ni, Pb, Zn) were measured using E. agilis system (E-Tox), an automated biomonitoring system. The E-Tox measures cell movement parameters, such as velocity, motility, and forms of the cells, as biological endpoints. $EC_{50}$ values from the E. agilis biomonitoring test were compared with the literature data from the tests with Daphnia magna, Vibrio fischeri and Euglena gracilis. Measurement of the E. agilis movement behavior and D. magna acute toxicity test were also conducted for the wastewater samples. E. agilis is less sensitive than D. magna but is comparable to or more sensitive than V. fischeri and E. gracilis for the heavy metals tested in this study. E. agilis shows prompt changes of these parameters for the toxic metal plating wastewater. Major advantages of the E-tox are automatic, easy to handle and fast ecotoxicity monitoring system compared to other biological test systems. These results imply that E. agilis biomonitoring test using E-Tox can be a putative ecotoxicity test as a good early warning tool for the monitoring of toxic wastewater.

  • This paper presents and analyzes field test results of E-VSB(Enhanced-VSB) system proposed by Zenith/ATl and adopted ATSC standard. In the field test, according to types of antennas we measured reception possibility, noise margin, ease of reception to analyze performance improvement of E-VSB system at each outdoor/indoor test point. Also, we verify a backward compatibility between E-VSB and conventional 8-VSB system and check selection of test point, and configuration of transmitter and test vehicle. By the field test results, E-VSB system did not only outperform over 8-VSB system at severe multipath environment such as indoor reception, but also verified backward compatibility with it.

  • This research has designed and implemented the standard conformance test system for e-Business solutions that supports the ebXML, which is currently being focused on as the leading electronic commerce framework. The adoption of standards such as ebXML is probably the best way to achieve interoperability among electronic commerce systems, and more and more e-Business solutions around the world are supporting ebXML. This research primarily discusses the concept and needs for the standard conformance tests on e-Business solutions. The standard conformance test system is developed based on the detailed specifications of the ebXML framework. This system was used to test commercial e-Business solutions supporting ebXML.

  • Several methods for rapid and accurate detection of VTe-producing E coli were established. These methods contain beta-glucuronidase-secretion test, beta-haemolysis-production test in blood agar, verocytotoxicity test, and PCR. All of the VTe-producing strains made beta-haemolysis on 5% sheep blood agar. VTe-producing strains secreted beta-glucuronidase whereas 0157:H7 strains producing VTI or VTII did not secrete that enzyme. Verocytotoxicity test was established for rapid diagnosis. VTe detection was rapider in Vero cell suspension than Vero cell monolayer. In PCR, there was a positive result only in VTe-producing E coli, not in VTI or VTII-producing E coli. In this experiment, 165 strains of E coli were islated from feces or intestinal contents of post-weaning piglets showing nervous sign or diarrhea. And 20 strains of E coli that produced VTe were selected by verocytotoxicity test and PCR. According to these experiments, there was a direct correlation between verocytotoxicity test and PCR. And verocytotoxicity test is recommended as a routine diagnostic method and PCR does as a accurate diagnostic method to detect VTe-producing E coli.

  • The fluorescent-antibody-to-membrane-antigen (FAMA) test is regarded as the "gold standard" to detect protective antibodies to varicella-zoster virus (VZV) because of its high sensitivity and specificity. Because the classic FAMA test uses an infectious virus for detection of antibodies to VZV, it is labor-intensive, and also requires special equipment for handling the virus. For this reason, we attempted to develop a simple and safe FAMA assay. Because VZV glycoprotein E (gE) is one of the major VZV glycoproteins, we used the gE protein for the FAMA test (gE FAMA). Here, we demonstrate that overexpression of gE in HEK293T cells can be used to measure antibodies in human serum, and that gE FAMA titers are closely correlated with gpEIA ELISA data. These results indicate that our gE FAMA test has the potential to measure antibodies to VZV.

  • Feasibility tests on using liposomes for detecting food-borne pathogenic bacteria were studied with E. coli 0157:H7 as a model analyte. lmmunoliposomes, whose surface was conjugated with anti-E. coli 0157:H7 IgG and which encapsulated the marker dye, sulforhodamine B, were used for the detection label. Among the feasibility tests, the first test was to use a test-strip on which antibodies to anti-E. coli O157:H7 IgG were immobilized. In this format, immunoliposomes that did not bind to E. coli O157:H7 in sample were captured and then exhibited a visible signal which was inversely related with the number of E. coli O157:H7 in sample. The second test was a direct liposome assay followed by immunomagnetic separation. In this format, immunoliposomes which were bound to E. coli O157:H7 were lysed with detergent and produced a signal which was proportionally related with the number of E. coli O157:H7 in sample. The results from both formats indicate that liposomes can be utilized as a detection label.

  • Allergy is conditions when a hypersensitivity reaction happens with a certain element, called as an allergen, which is commonly not reactive to ordinary individuals. Allergic diseases involve various organs or systems in the body. The purpose of allergy tests is to make a diagnosis of allergic diseases and to identify the affecting allergens. In vivo tests, more relevant in clinical situation, include skin test, patch test and provocation test. In in vitro tests, there are specific IgE test, histamine releasing assay, and lymphocyte activation test, safer and more objective than in vivo tests. In the view point of clinical practice, skin test, provocation test, total IgE test and specific IgE test were reviewed in depth.

  • Recently the design of SoCs(System-on-Chips) in which TCM is embedded for high speed operation increases rapidly. In this paper, a parallel test structure for eDRAM-based TCM embedded in SoCs is proposed. In the presented technique, the MUT (Memory Under Test) is changed to parallel structure and it increases testability of MUT with boundary scan chains. The eDRAM is designed in structure for parallel test so that it can be tested for each modules. Dynamic test can be performed based on input-output data. The proposed techniques are verified their performance by circuits simulation.
