Contemporary maintenance management: process, framework and supporting pillars

Abstract: This paper presents a holistic framework for managing the maintenance function heretofore inundated by myriad tools, trappings, practices, and prescriptions. It begins by reviewing the concepts, state-of-art processes and standards available to help maintain today’s complex systems. It then proposes a framework in which to couch the various maintenance functions in an organization. In doing so, this paper characterizes factors that breed complexity in maintaining today’s operations. Next, it closely analyzes the strategic, tactical and operational aspects ofmaintenance and sets up a structure to help complete the tasks at each ofthese levels. The term “process” in this paper implies actions directly associated with maintenance, while “framework” embodies the supporting infrastructure. The results are clear statements of(1) the f required of enablers such as IT to abet maintenance; (2) the distinctive capabilities extended by modern maintenance engineering; and (3) the critical requirement of relationship competencies in maintenance. This work sums up decades spent in maintenance shops, engineering, standardization, and research in maintenance management. 2004 Elsevier Ltd. All rights reserved.

Metabolic Syndrome and Periodontitis: Is Oxidative Stress a Common Link?

Abstract: A review of pathological mechanisms that can explain the relationship between periodontitis and cardiovascular disease (CVD) is necessary to improve the management of both conditions. Metabolic syndrome is a combination of obesity, hypertension, impaired glucose tolerance or diabetes, hyperinsulinemia, and dyslipidemia. All these have been examined in recent years in terms of their relationship to periodontitis. Reviewed data indicate an association between some of them (body mass index, high-density lipoprotein-cholesterol [HDL-C], triglycerides, high blood pressure, among others) and periodontitis. Oxidative stress may act as a potential common link to explain relationships between each component of metabolic syndrome and periodontitis. Both conditions show increased serum levels of products derived from oxidative damage, with a pro-inflammatory state likely influencing each other bidirectionally. Adipocytokines might modulate the oxidant/anti-oxidant balance in this relationship.
