SAFETY EDUWORKS is  the EDUWORK  networking cluster for Occupational Safety and Health. Instead of doing it in the spare (free) time of the employees, employees could be trained during the actual work. This is money saving also for the management and assures a better safety training  for the employee.

SAFETY EDUWORK should be based on a risk ontology- that should include the most  significant content , should be knowledge based and should be available for continous upgrades.
A key reason for using ontologies in risk research is that ontologies are offering structured means to represent risk as we know it today. Ontologies can specify the context in which risks occur, the hazards on which risk is based, the risk trigger and also the aftermath effects. Ontologies could be also a collaborative instrument- on which a lot of safety experts from various domains could give a hand in better understanding and better training. Ontologies are meaning:
1. Selected and processed knowledge in a proper form;
2. Continuous development and upgrade from various sources. Moreover, considering the need to have the main ontology public, the development tools are allowing to keep some specific parts of the ontology (like the ones that are involving IPR s  or process sensitive ontologies) out of the access of unwanted  readers.
This paper describes an initiative started with the late Trevor Ketz in 2004 and near the finish now- regarding the development of a safety seed of knowledge- as we conceived then like a knowledge base and in its final form as open risk ontology.
The usages of this ontology are focused mainly in the safety training process- that could be now planned on the map of the enterprise workplace and could be tailored to assure the specific notions needed in order to perform an optimal safety service- while not forgetting the eventual connections with more boarder terms.
Every term in the ontology is loaded with the necessary knowledge- as content when possible or at least as a link to the  content.
The next step in the development would be the on-line transposition and making the ontology multi-lingual. Moreover, the  enteprises that are implementing EDUWORK would use the instrument as the start-up basis for training planning and schedule.
The next figures are presenting some images with a test ontology.

Figure 1. Ontological tree

We have experimented with a lot of ontological instruments till finding the most proper one- the one for EDUWORK. 

Figure 2. Text option for ontology

Finally we found a free and acceptable instrument- IHMC Cmap. Their Logo is presented in figure 3. 

Figure 3 IHMC Cmap Logo

Cmap- as we have used it- works with Concepts and Links between concepts. 
For every Concept there could be included additional resources (as doc, xlm and pdf files), links or short pieces of information.

 Figure 6. Identification of concepts on the ontological map

We found that  risk ontologies are extremely usefull given the restrictions of time and resources of EDUWORK. The learner could search after the training specific concepts inside the ontological map- together with the learning resources. Alternatively, at introducing a new concept- the map could be accessed in order to see the new concept place into the whole story.
A global image of the ontological map in one of the development stages is given below.

Figure 7.Global image of the demo risk ontology

The ontology could be translated into a Web page- that could be accessed on-line by the students. Image 8 shows the capture from the site. 

Figure 8. The ontology turned into an interactive site. 

The resources could be accessed interactively.The resulting propositions inside the ontology could be illustrated like in the next figure.  

Figure 9. Illustration of the propositions of the ontology.

The ontological approach is a very useful one- in the wake of the training part of the system. The development of the training content could be made using the developed ontology which could guide the tutor in selecting and processing the best content.

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. It is a supporting toolset that allows managers to bridge the gap between control requirements, technical issues and business risks. COBIT was first released in 1996; the current version, COBIT 5, was published in 2012. Its mission is “to research, develop, publish and promote an authoritative, up-to-date, international set of generally accepted information technology control obj…


Așa după cum s-a văzut dintr-o postare trecută, graful de risc poate fi un instrument util- și nu numai în cazul bolilor profesionale. Vom adapta în continuare  teoria existentă la teoria și practica din România și vom detalia câteva aspecte considerate de interes.
Este interesant de adaptat  graful de risc pornind de la clasicul sistem Om-Mașină folosit în practica de specialitate din domeniul SSM din România. În acest sens, folosind experiența existentă și datele statistice putem dezvolta în mod corespunzător- așa cum se prezintă în continuare în acest material.
