Abstract
The aim of this research is to analyse the students' attendance at the Faculty of Business and Economics. The study is divided into two parts: the first part analyses why some students are not motivated to attend lectures and practical hours and the second part analyses the impact of students' attendance (motivation, bonus) in lectures and practical hours and their final success. This paper provides results of a survey completed at the beginning of the summer semester and results of the final success in three courses for the academic year 2010/11 (Business Mathematics, Statistics and Managerial Economics) with first, second and third-year students at the Faculty of Business and Economics, at South East European University in Tetovo. This paper uses logical regression to give an overview of the impact of students' attendance (motivation, bonus) at lectures and practical hours in their final success. Results show that, besides other daily engagements during studies, students have other excuses for absence from lectures and practical hours such as conditions, management and methods of teaching in the Faculty. Final results of three subjects which are considered as more practical show that attendance has a big influence in students' final success. The software MedCalc was used for the elaboration of data.

Abstract
E.indica specie is a native grass that grow almost everywhere in Nigeria. This study was designed to assess the inhibitory effect of high level accumulation of the metals; Cu, Cd, Cr, and Ni on seed germination and growth E. indica. Sets of laboratory pot experiment were conducted. Viable seeds of the experimental grass were seeded into one kilogram soil amended with the metals and placed in plastic pots. The various levels of: 50, 250, 80, and 250 mg/kg for Cd, Cu, Cr, and Ni respectively. Our results show that seedling growth is more sensitive to the metals; Cu, Cr, Cd, and Ni in comparison to seed germination, Cu, Ni, and Cr displayed relatively strong toxicity whereas Cd expresses mild symptoms of toxicity. This observation could be due to the high accumulated levels of the metals in the root: 155.4, 124.3, and 226.9 (μg/g) for Cu, Cr, and Ni respectively. Although some the grass survived the effect of the high levels of the metals, continuous cropping is suggested for high biomass production.

Abstract
The quality of fresh sardine (Sardina pilchardus) has been evaluated using 8 groups of the fish stored under 2 modes of preservation: chilling (2°C) for 5 days and icing (0 – 2°C) in 4 days. The chemical evaluation made showed that the total volatile basic nitrogen parameters and trimethylamine constitute suitable indices for the evaluation of the spoilage of sardine and of the proposed standards of control. The onset of deterioration and the organoleptic limit of acceptability coincide well with the results of the chemicals analysis. A negative correlation was established between the evolution of the organoleptic parameters and the content of total volatile basic nitrogen and trimethylamine, demonstrating that these two parameters can be used as indicator of the deterioration of sardines.

Abstract
We report a case of perimortem caesarean section following cardiac arrest during labour and review the literature.A perimortem caesarean section was conducted on a 29 year old woman, with resultant neonatal survival and maternal death. It is a procedure rarely done and standard National guidelines are lacking. Peri mortem (PMCS) caesarean section in the case of cardiac arrest is the most important life saving procedure. It should be commenced within 5minutes of initiating cardiopulmonary resuscitation. Timely intervention is crucial in ensuring maternal and neonatal survival.

Abstract
Values are an inherent part of all decision processes. Hence, values are at least implicity included in all expert systems intended for decision support. This paper outlines the concepts and methodology, which are based on the principles and procedures of decision analysis, to address explicity the values in an expert system logically and consistently. Implementation of the concepts and methodology involves the elicitation of values using the same general approach as that used by knowledge engineers to explicate expert knowledge.

Abstract
Interactive planning systems are a relatively new phenomenon in the practice of operations research. We review the role of quantitative models and methods and the need for man-machine interaction in practical planning situations. We specify a number of desirable functional requirements of an interactive planning system, and discuss the graphical user interface and the use of various representations. We comment on the types of solution strategies involved and relate some of our own experience.

Abstract
Dealing with uncertainty of facts and rules in an inference system will be discussed. The assessment and evaluation of uncertainties will be done within Dempster's and Shafer's theory of evidence. The relation between this theory and classical probability theory will be stressed.

Abstract
First the concept of a decision support system (dss) is described. Then the first approach, in which the development of a network of models forms the kernel, is given. An example illustrates this approach. Then, architectures of decision support systems according to the first approach are given. Afterwards a second approach is considered, in which an (abstract) dss machine is described that can be tuned to specific decision situations. Finally the applicability of this approach is illustrated with an example.

Abstract
This paper reviews a part of the literature on behavioral decision research (policy capturing, psychophysics of numerical judgments and cognitive illusions) and examines implication for knowledge elicitation in expert systems. The literature on policy capturing demonstrates that simple and compact numerical models of expert knowledge can be built, but that experts are poor in verbalizing the knowledge expressed in them. The psychophysical literature indicates that numerical encoding of expert knowledge may be difficult and biased, but that it has definitive advantages over qualitative elicitation schemes: Numerical encoding forces hard throught, encourages precision, and allows to access a substantial computational apparatus. The literature on cognitive illusions suggests that the expert knowledge one elicits may be an illusion. The review concludes by recommending to use numerical judgments and explicit models by experts where possible, and to decompose the elicitation task in order to avoid cognitive illusions.

Abstract
Within the range of new technology applications 'flexible manufacturing systems' are expected to give a productivity edge in market competition. Their function is based on a decentralized manufacturing organisation in form of semi-autonomous workgroups. These workgroups, consisting of a small number of workers, form so-called production cells. In this paper we want to present considerations on the architecture of a decision support system for personnel assignment scheduling within production cell organisation. Beside this, social, organisational, and qualificational aspects and requirements for the use of such systems are discussed.
