    For more about the East-West Center, see http://www.eastwestcenter.org/Over the next 30 years, the share of South Korea's population age 65 and older is projected to grow from 15 to 40 percent. Given this extreme rate of population aging, Korean policymakers face two critical challenges--ensuring an adequate level of support for the elderly while maintaining robust economic growth. Keeping healthy older people in the labor force can help achieve both these goal

    The Role of Evaluability Bias and the Fairness Effect in the Escalation of Commitment to Troubled Software Product Development Projects

    New software product development entails considerable risks. One significant risk is that decision makers can become overly committed to troubled software product development projects (i.e., escalation of commitment). While prior research has identified factors that promote escalation in information technology projects, there has been little attempt to leverage the context of software product development, which can include evaluating attributes of a software product under development and weighing a personal financial reward tied to a successful product launch. In this study, we conducted two experiments to investigate how evaluability bias concerning software attributes and the fairness effect that arises from the relative amount of a personal financial reward influence the escalation of commitment to troubled software product development projects. Our findings suggest that the escalation of commitment to troubled software product development projects is influenced by both evaluability bias, which affects the perceived attractiveness of a software product under development, and the fairness effect, which influences the perceived attractiveness of a personal financial reward tied to a successful product launch. This study contributes to both the information systems literature and the escalation literature by providing novel theoretical explanations as to why escalation occurs in the context of new software product developmen

    NtGCM User's Manual: 1.1 (High Pressure High Temperature Laser based) Nanotube Growth Chamber Monitor

    Get PDF
    This manual describes the installation and use of NtGCM software. NtGCM is software designed for monitoring the growth of nanotubes in a high temperature and high pressure chamber using a laser*. NtGCM software monitors a dozen dierent parameters that are important to understanding the growth of the nanomaterials including the laser input power, the temperature at eight separate locations inside and outside the growth chamber, as well as the pressure and ow rate of the gaseous media that control the environment in the chamber. The measurements are all made in real time. The program features a robust user account management layer and a rich data display manager that allows plotted data, displayed units and other parameters to be changed on the y for the operator's convenience

    Human error control in the collaborative workflow modeling tool based on GEMS model

    Business process should support the execution of collaboration process with agility and flexibility through the integration of enterprise inner or outer application and human resources from the collaborative workflow view.Although the dependency of enterprise activities to the automated system has been increasing, human role is as important as ever.In the workflow modelling this human role is emphasized and the structure to control human error by analysing decision-making itself is needed.Also, through the collaboration of activities agile and effective communication should be constructed, eventually by the combination and coordination of activities to the aimed process the product quality should be improved.This paper classifies human errors can be occurred in collaborative workflow by applying GEMS(Generic Error Modelling System) to control them, and suggests human error control method through hybrid based modelling as well.On this base collaborative workflow modeling tool is designed and implemented. Using this modelling methodology it is possible to workflow modeling could be supported considering human characteristics has a tendency of human error to be controlled

    The mechanism of low-concentration sodium nitroprusside-mediated protection of chondrocyte death

    Sodium nitroprusside (SNP), a widely used nitric oxide donor, has recently been shown to mediate chondrocyte apoptosis by generating reactive oxygen species, whereas more potent nitric oxide donors do not induce chondrocyte apoptosis. The present study was performed to investigate the protective effect of a low concentration of SNP upon the cytotoxicity of chondrocytes to higher concentrations of SNP, and to elucidate the underlying mechanism. Human osteoarthritis chondrocytes were cultured as monolayers, and first-passage cells were used for the experiments. Chondrocyte death induced by 1 mM SNP was completely inhibited by pretreating with 0.1 mM SNP. This protective effect of SNP was replicated by the guanosine-3',5'Îș-cyclic monophosphate analog, DBcGMP. Protection from chondrocyte death conferred by 0.1 mM SNP was mediated by heme oxygenase 1 (HO-1), as was revealed by the increased expression of HO-1 in 0.1 mM SNP pretreated chondrocytes and by the reversal of this protective effect by the HO-1 inhibitor, zinc protoporphyrin. SNP-mediated chondrocyte protection correlated with the downregulation of both extracellular signal-regulated protein kinase 1/2 and p38 kinase activation. SNP at 0.1 mM induced significant NF-ÎșB activation as revealed by electrophoretic mobility shift assays, and the inhibition of NF-ÎșB by MG132 or Bay 11-7082 nullified 0.1 mM SNP-mediated chondrocyte protection. The upregulation of p53 and the downregulation of Bcl-(XL )and Mcl-1 by 1 mM SNP were reversed by 0.1 mM SNP pretreatment at the protein level by western blotting. Our study shows that priming with 0.1 mM SNP confers complete protection against cell death induced by 1 mM SNP in human articular chondrocytes. This protective effect was found to be correlated with the upregulation of both HO-1 and NF-ÎșB and with the concomitant downregulation of both extracellular signal-regulated protein kinase 1/2 and p38 activation

    SNP@Ethnos: a database of ethnically variant single-nucleotide polymorphisms

    Inherited genetic variation plays a critical but largely uncharacterized role in human differentiation. The completion of the International HapMap Project makes it possible to identify loci that may cause human differentiation. We have devised an approach to find such ethnically variant single-nucleotide polymorphisms (ESNPs) from the genotype profile of the populations included in the International HapMap database. We selected ESNPs using the nearest shrunken centroid method (NSCM), and performed multiple tests for genetic heterogeneity and frequency spectrum on genes having ESNPs. The function and disease association of the selected SNPs were also annotated. This resulted in the identification of 100 736 SNPs that appeared uniquely in each ethnic group. Of these SNPs, 1009 were within disease-associated genes, and 85 were predicted as damaging using the Sorting Intolerant From Tolerant system. This study resulted in the creation of the SNP@Ethnos database, which is designed to make this type of detailed genetic variation approach available to a wider range of researchers. SNP@Ethnos is a public database of ESNPs with annotation information that currently contains 100 736 ESNPs from 10 138 genes, and can be accessed at and or directly at
