208. Revisiting “The Meaning of Of” as a Theory for Collaborative System of Systems.

Author

Baldwin, W. Clifton, Sauser, Brian J., and Boardman, John

Abstract

At the 2006 IEEE International Conference on Systems of Systems Engineering, Boardman and Sauser presented a set of characteristics based on an integrative review of the literature. These characteristics are the foundation of the Boardman–Sauser system of systems (SoS) theory. We accept this theory as the basis of collaborative SoS and desire a means to validate this assertion. While numerous simulations have been published, the target SoS is usually a specific implementation. These specialized simulations produce results applicable primarily to the system under study but not necessarily SoS in general. Simulating the mathematical model of the Boardman–Sauser SoS theory in the form of an agent-based model produces results that can be compared with chemical reactions. This paper contends that the formation of molecules from atoms is an analog of systems forming any collaborative SoS, which we call our molecule organization model. The result is a supported logical argument that validates the Boardman–Sauser SoS theory as definitive of a generic SoS with behavior applicable to collaborative SoS. This paper seeks to provide a unique contribution to the SoS body of knowledge by increasing our understanding of collaboration in an SoS, so we may better understand their health, maintenance, replication, and evolution.

Abstract

Use of porcelain denture teeth may be desirable in many clinical situations, including implant-supported prostheses. However, lack of space because of frameworks often precludes the use of conventional retention by diatorics and pins. Adhesion of porcelain denture teeth to denture resin could also stiffen and possibly strengthen dentures and decrease stain ingress between porcelain teeth and resin denture bases. Unlike previous studies that investigated the bond between conventional feldspathic metal-ceramic porcelain and bis-GMA based composite resin, this study investigated adhesion of denture tooth porcelain to polymethyl methacrylate (PMMA). High-energy air abrasion, hydrofluoric acid etching, and the use of a general purpose bonding agent resulted in an improved bond strength of heat-cured denture PMMA bonded to denture tooth porcelain. Silane, coating did not improve bond strengths, and conventional air abrasion was no more effective than polishing with 600-grit, silicon carbide. Storage in water and artificial aging substantially decreased bond strengths. The strongest bond strengths were achieved by a high-energy-abrasion + etching + multiple-purpose bonding-agent treatment, but a simpler etching + multiple-purpose bonding-agent treatment also produced reliable results. A laboratory technique was suggested. The role of surface treatment in the mechanism of adhesion was examined with scanning electron microscopy. High-energy abrasion produced a slightly more detailed initial topography than conventional air abrasion, but after etching, the high-energy topography became much more detailed. Surface topography alone did not account for all differences found.

Abstract

Current trends for health care reform and increasing emphasis on managed care threaten to erode the base of patients of many practices. A constant flow of new patients is critical to the success of a dental practice. This article discusses the nature of business markets and similarities between industries and their correlation to the delivery of prosthodontic services. The purpose of this article is to offer a strategy for increasing new patient flow without the use of advertising.

Abstract

States that if you are too timid to dive into the overheated stock market, too unhappy with paltry returns to stay in cash, there is a plausible middle course: a package of bond mutual funds. There are many circumstances in which investors, even well-heeled ones, do better buying their bonds through a fund than directly. Four rules of bond fund investing; Recommendations.

Abstract

Determining the optimum fee for prosthodontic services is difficult. Most methods of determining fees are based on comparisons with other practitioners or with established fee schedules. However, comparisons alone are inadequate because they ignore the practitioner's underlying costs. Since it costs each individual practitioner different amounts to produce dentistry, dental fees should be highly individualized. This article presents a model for evaluating fees for prosthodontic services based on both underlying costs and intangible variables such as the dentist's skill, experience, and quality of care.
