Objectives: To build and imprint knowledge into student’s skills and abilities is an essential desire for every  educational process and tutorial system. In this respect, the main objective of our research was the study (and development) of an efficient, optimal and relative inexpensive knowledge structure, called eduknowledge. This structure is specially taylored in order to assure an individual and optimal learning process. The paper presents the most significant aspects of this research together with applications in medical training, especially in diagnosis.
Methods: We had used an inter-disciplinary, cross-link approach in our research, taking into account some significant aspects like:
-the financial aspect- we have tried at the begining to use just Open Source instruments- but they were not sufficient in order to build our structures. So we have obtained free access to some efficient development tools combining them with the available Open Source software.
-the need for a self-training instrument that should use knowledge instead of data- in order to efficientize the process of  skills acquirement.
-the necessity for knowledge engineering – especially regarding knowledge mining and knowledge update.This lead us towards topic maps as the major way in order to obtain an efficient knowledge upgrade.
-the necessity for knowledge distributed structures- in order to assure an efficient knowledge generation/dissemination process these structures- build around knowledge seeds – could be easily developed at specific structures (like universities, important medical centers, etc.) and inter-connected in order to assure specific chunks of knowledge.

Obtained results: Till now our results were focused towards the development of a conceptual frame for such knowledge structure, modelling and testing this frame in real situations and transition towards development of a prototype.
Our conceptual frame is considering two distinct structures:
-The Front (Eduknowledge based tutorial system) based on:
-the extensive use of  highly structured knowledge in order to obtain quickly the desired skills;
-the optimal inter-relation between the individual student- with his/hers
            specific learning style and learning attitudes and the tutor (tutorial
            system), correlated with  an efficient knowledge dissemination and
-The Logistics (knowledge storage and upgrading structures) based on:
-an inter-connected structure of specific knowledge bases, evolved from knowledge seeds , able to contribute actively at specific knowledge development (for example heuristic diagnosis methods for a specific disease- from various medical centers around the world- taking into account specific aspects regarding environmental conditions, race, age, etc.);
-upgrade on-line from other knowledge sources- through knowledge maps.
As a highly structured knowledge structure, focused towards the goal of mastering specific techniques- we found during our research eduknowledge as, perhaps the best suited tool for medical training. The learning process improved its efficiency by 17%...35.4% taking into account other computer based training systems and by 45% taking into account classic tuition. The new method  uses extensively knowledge especially structured in order to achieve a peculiar goal-it is based on individual interaction between the training system and the trainee, the subject of training could individually improve his/hers training paths and rise the efficiency of personal training contributing to the increase in the whole training process. After understanding the basics in his specific activity the trainee interacts with various scenarios, in order to use the acquired knowledge and develop his abilities in virtual environments re-enacting the real ones. After the end of training the learned abilities will be naturally and efficiently imprinted in the trainee which will use them as an integrant part of the work process.
A generic image of eduknowledge is presented in the next figure.

Conclusion: Our paper presents the most significant aspects of a research having as a final result  a libre based, low cost eduknowledge training system, with very important applications in medical training. This system could be easy upgraded using topic maps. Also, even if  it is developed especially for mastering diagnosis processes,  it could be easy focused towards various  specific medical techniques.

GENERAL ASPECTS Safety domain of research is by excellence a domain based on expertise. Textbooks and theoretical knowledge are good but the safety expert which inspects three times a day a certain part of an enterprise is the ultimate safety dealer here. A lot of expertise is transformed into lessons learned- that are used for training and improvement of existing safety attitudes. On the other part, this expertise could be also valued in order to build optimal and effective safety assessment systems. An expert system is software that emulates the decision-making ability of a human expert. In our case- the expert part should interrogate the specific employees regarding safety aspects of an enterprise. The next figure illustrates how a safety expert, with the necessary knowledge into the problem could impr…


Analiza cauzelor rădăcină este o metodă extrem de folosită de către managementul de performanță  din firmele dezvoltate. Metoda este considerată ca o metodă primară- care trebuie utilizată în primele faze ale analizei specifice procesului managerial. Ne propunem să prezentăm o metodă de analiză a cauzelor rădăcină care să poată fi aplicată atât pentru managementul calității cât și pentru managementul securității – ținând seama de faptul că în cea mai mare parte, cauzele rădăcină ale problemelor de calitate și problemelor de securitate și sănătate sunt comune. Figura 1 prezintă modul  global de analiză pentru cauzele rădăcină Din figură se poate observa că avem 2 procese distincte: ·         -un proces de identificare- care va fi realizat pe baza metodei cunoscute și ca 5 W ( 5 Why); ·         -un proces de analiză; procesul de analiză urmărește: o   stabilirea cauzelor specifice managementului calității și managementului de SSM; o   ierarhizarea cauzelor identificate;

KPI definitionA key performance indicator(KPI) is a measure of performance, commonly used to help an organization defineand evaluate how successful it is, typically in terms of making progress towards its long-term organizational goals.
–KPIs provide business-level context to security-generated data –KPIs answer the “so what?” question –Each additional KPI indicates a step forward in program maturity –None of these KPIs draw strictly from security data
COBITControl Objectives for Information and Related Technology (COBIT) is a framework created by ISACA for information technology (IT) management and IT governance.
