Building teams has a fundamental impact for execution of research and development projects. The teams appointed for the needs of given projects are based on individuals from both inside and outside of the organization. Knowledge is not only a product available on the market but also an intangible resource affecting their internal and external processes. Thus it is vitally important for businesses and scientific research facilities to effectively manage knowledge within project teams. The article presents a proposal to use Fuzzy AHP (Analytic Hierarchy Process ) and ANFIS (Adaptive Neuro Fuzzy Inference System) methods in working groups building for R&D projects on the basis of employees skills.

The selection of an effective team of employees is crucial to proper management of the company. The success of the project often depends on the competencies of employees who carry out those projects. Therefore, the selection of the workers, whose competences complement each other in terms of subject matter, in terms of personality, and also in practical terms, is very important. This article presents the proposal of applying the FAHP (fuzzy analytic hierarchy process) and TOPSIS (technique for order preference by similarity to an ideal solution) methods as a tool to facilitate the management of human resources in the metal production factories based on the skills of employees.

Because its chronic, progressive and irreversible nature it is one of the most common cause of work incapacity. It is also a common cause of disability in people in six decade of life.

Objective: The aim of this study was to evaluate the effect of cryogymnastic on quality of life and functional efficiency of patients with knee osteoarthritis.

Material and methods: The study consisted of group of 50 people diagnosed with osteoarthritis of the knee (gonarthrosis). Patients were tested twice. First examination was conducted before the start of therapy, a second examination was conducted after 10 treatments cryotherapy. To evaluate the results of cryogymnastic we used goniometric measurement, WOMAC questionnaire and functional test Up & Go.

Results: We found that applied local cryotherapy and exercise in studied group had been effective in increasing joint range of motion, improving quality of life and patients’ functional efficiency.


1. Our treatment for patients with knee arthritis after local cryotherapy and exercises improved significantly joint range of motion, quality of life and functional efficiency.

2. Local cryotherapy is a safe procedure and well tolerated by patients with knee osteoarthritis.
