ABSTRACT:The concepts of structured and object-oriented programming methods are not relatively new but these approaches are still very much useful and relevant in today's programming paradigm. In this paper, we distinguish the features of structured programs from that of object oriented programs. Structured programming is a method of organizing and coding programs that can provide easy understanding and modification, whereas objectoriented programming (OOP) consists of a set of objects, which can vary dynamically, and which can execute by acting and reacting to each other, in much the same way that a real-world process proceeds (the interaction of realworld objects). An object-oriented approach makes programs more intuitive to design, faster to develop, more amenable to modifications, and easier to understand. With the traditional, procedural-oriented/structured programming, a program describes a series of steps to be performed (an algorithm). In the object-oriented view of programming, instead of programs consisting of sets of data loosely coupled to many different procedures, objectoriented programs consist of software modules called objects that encapsulate both data and processing while hiding their inner complexities from programmers and hence from other objects. @ JASEM Structured programming can be viewed as the pulling together, or synthesization of such ideas as program modularity and top down design, and the concrete representation of them at the program-coding level. It is a manner of coding and organizing programs that makes them easier to understand, to test and to modify. Results have demonstrated that employed together with other improved programming technologies, can lead to spectacular increases in programmer productivity and correspondingly spectacular decreases in the error rate of resultant code (Champeaux, 1990), and(Istatkova, 2001). Structured programming methodology tries to resolve the issues associated with unconditional transfers to enable programmers follow the logic of programs.

“…This possibility was already suggested, for example, by Ivar Jacobson in a conference panel [12]. Briefly, we can comment that the UML meta-model defines an association between ModelElement and Statemachine, called behavior [56, p. 2-145].…”

“…There were several attempts to combine these two approaches [8][9][10][11], but none of them is widely used. Although some researchers [12] argue that object-oriented analysis and structured analysis are fundamentally incompatible, we believe that the topic deserves more research effort in order to understand if the integration can be effectively achieved and, if a positive answer is obtained, how that can be accomplished.…”

Integration of DFDs into a UML-based Model-driven Engineering Approach

The main aim of this article is to discuss how the functional and the object-oriented views can be inter-played to represent the various modeling perspectives of embedded systems. We discuss whether the object-oriented modeling paradigm, the predominant one to develop software at the present time, is also adequate for modeling embedded software and how it can be used with the functional paradigm. More specifically, we present how the main modeling tool of the traditional structured methods, data flow diagrams, can be integrated in an object-oriented development strategy based on the unified modeling language. The rationale behind the approach is that both views are important for modeling purposes in embedded systems environments, and thus a combined and integrated model is not only useful, but also fundamental for developing complex This article is an extension of two papers [1,2] published in the systems. The approach was integrated in a model-driven engineering process, where tool support for the models used was provided. In addition, model transformations have been specified and implemented to automate the process. We exemplify the approach with an IPv6 router case study.

ABSTRACT:The antioxidant activity of the aqueous crude extract of Ocimum gratissimum Linn. leaf on the basal and traumatized (cadmium-induced) serum levels of alkaline phosphatase (ALP), total acid phosphatase (ACP T ) and prostatic acid phosphatase (ACP P ) of the male guinea-pig (GP) were evaluated. Preliminary experimentation showed that the effects of the aqueous crude extract of O. gratissimum on basal serum phosphatases were slightly more in the oral than the intraperitoneal (i.p) route. Oral administration of 20mg of O. gratissimum caused a timedependent decrease in the basal serum levels of ACP T and ACP P without an effect on ALP values. The inhibitory effects compared to the control were maximum at 4 hours. Furthermore, O. gratissimum given orally, caused significant dose-dependent decreases (p<0.05) of the basal serum levels of ACP T and ACP P at p<0.05. Basal serum concentrations of ACP T and ACP P changed from 23.50±1.04 and 7.50±0.29 to 8.25±0.75 and 2.25±0.29 IU at 20mg, representing 65 and 70 % decreases respectively. In contrast, 0.25-8mg/kg of cadmium (Cd) given intraperitoneally, caused significant dose-dependent increases (p<0.05) in the phosphatase enzymes. However pretreatment with 5mg of the crude extract, which on its own had little effect on basal serum phosphatase levels, followed by i.p administration of Cd, caused a reversal of the Cd-induced dose-response curves on the various phosphatase levels to negative values. These results may be due to the oxidative and the antioxidative biochemical antagonistic properties of the agents used in these experiments. They may also be due to enzyme conformational changes and effects of eugenols and flavonoids in the crude extract of O. gratissimum. @ JASEM Oxidation is an essential process in all organisms which involves redox reactions. These reactions normally generate reactive oxygen species (ROS) or highly reactive free radicals that can react virtually with all cell components to cause tissue injury (Collier et al., 1992). Exogenous sources of free radicals include tobacco smoke, ionization radiation, certain pollutants such as cadmium, vanadium, crude oil, organic solvents and pesticides (Robinson et al., 1997). The resulting oxidative free radicals are obligate intermediates of many metabolic reactions but may also cause pathological damage (Floyd et al., 1990). Similarly, antioxidation is the reversal of the above described processes mediated through scavenging of the free radicals, by dismutase enzyme systems, and phenolic-rich compounds such as flavonoids (Sardesai 1995;Rice-Evans et al., 1996). The body has evolved a number of interrelated antioxidant mechanisms to maintain redox homeostasis (Toyokuni et al., 1999). These antioxidant mechanisms include antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), gluthathione peroxidase (GSH-Px), heme oygenase (HO) etc (Ames et al., 1993;Sardesai 1995;Sies, 1997;Vertuani et al., 2004). A disturbance in the balance between the production of reactive oxygen species or free radicals an...
