Intelligence benevolent tools: A global system automating integration of structured and semistructured sources in one process

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 6 2004
Mbale Jameson
In this article, we investigate a global mechanism that merges and automates interoperability of heterogeneity structured and semistructured sources in one process. In particular, we introduce the intelligence benevolent tool (IBT) system comprised of tools like assertions, integration rules, conceptual model constructs, and agents that boost the architectural components' versatility to reconcile the semantics involved in data sharing. Going by the title, the term benevolent in this case refers to tools' ability to do what they are told to do. In this way, the tools shall rejuvenate the system's intelligence to withstand the test of time against the existing terrifically dynamic computer technology in the present and future information age. The first three IBTs are passive objects, whereas the agent has a strong versatility to perceive events, perform actions, communicate, make commitments, and satisfy claims. The IBT's vast intelligence allows the system to filter out and process only the relevant operational sources such as preferences (i.e., customer's interest) from the sites. In addition, the IBT's richness in knowledge and flexibility to accommodate various data models manages to smoothly link system-to-system or firm-to-firm regardless of any field such as engineering, insurance, medicine, space science, and education, to mention a few. © 2004 Wiley Periodicals, Inc.

Agrarian Transformation and Rural Diversity in Globalizing East Asia

INTERNATIONAL JOURNAL OF JAPANESE SOCIOLOGY, Issue 1 2004
Atsushi Kitahara
Abstract:, In East Asia the rural society is not a society based upon agricultural industry anymore and the peasant society with its long history has been disappearing. The occupation and income sources of rural inhabitants have diversified and among them those who specialized in farming are the minority. There is a shortage of rural labor, which used to be abundant in the past, and presently it is not as easy to hire the farm workers. The reason for the diversification of the rural occupations is, to put it simply, because people cannot live merely on farm income. Indeed the farm operation costs have become more expensive due to labor saving techniques, but the livelihood costs have become more expensive due the new uniform lifestyle standards from globalization. Electric machines and education are the typical of these increased costs. The background of this rural change is industrialization and urbanization in the context of globalization and its strong impact is penetrating into the rural society through the regional urban center as the relay point of the global mechanism. This change is different based upon the location of each rural society. Generally, rural societies around a big urban center enjoy opportunities for the younger generation, but remote areas have serious problems with few employment opportunities and a smaller youth population. To reproduce and sustain the regional society as a whole, it is necessary to attract younger people and make them stay. We should plan to develop a variety of industries and the resultant diversified work opportunities in the broader region beyond the narrowly demarcated village and community. Subsistence and commercial agriculture might merely be a part of such diversity. [source]

Regulation of nitrogen metabolism in Mycobacterium tuberculosis: A comparison with mechanisms in Corynebacterium glutamicum and Streptomyces coelicolor

IUBMB LIFE, Issue 10 2008
Catriona Harper
Abstract The mechanisms governing the regulation of nitrogen metabolism in Corynebacterium glutamicum and Streptomyces coelicolor have been extensively studied. These Actinomycetales are closely related to the Mycobacterium genus and may therefore serve as a models to elucidate the cascade of nitrogen signalling in other mycobacteria. Some factors involved in nitrogen metabolism in Mycobacterium tuberculosis have been described, including glutamine synthetase and its adenylyltransferase, but not much data concerning the other components involved in the signalling cascade is available. In this review a comparative study of factors involved in nitrogen metabolism in C. glutamicum and S. coelicolor is made to identify similarities with M. tuberculosis on both a genomic and proteomic level. This may provide insight into a potential global mechanism of nitrogen control in Mycobacterium tuberculosis. © 2008 IUBMB IUBMB Life, 60(10): 643,650, 2008 [source]

The unfolding story of the Escherichia coli Hsp70 DnaK: is DnaK a holdase or an unfoldase?

MOLECULAR MICROBIOLOGY, Issue 5 2002
Sergey V. Slepenkov
Summary We discuss recent experiments that have illuminated individual steps in the reaction cycle of the Escherichia coli Hsp70 molecular chaperone DnaK. Using this new information, we comparetwo distinctly different global mechanisms of action , holding versus unfolding , and argue that the available evidencesuggests that DnaK is an unfoldase.
