Economia : Seria Management , 2010,
Abstract: The textile industry is an industrial field that affects the environment, from the plant growth until the production process. The obtaining of environmental licence for Romanian companies that produce textile products is related to elaboration and implementation of a modern system for an environmental management, that consist in utilization of ecological technologies for finishing, in diminution the water and energy consumption, cleaning of waste waters, reutilization of cleaned waters, sustainable management of wastes. In this study, the surfactant categories used in the textile industry that fulfil the conditions of environment protection, are presented. Some exemplifications were made involving the existing surfactants in Romanian textile industry, obtained from both domestic and external production. Also, some recommendation are suggested regarding the utilization of surfactants manufactured from either vegetal oils or chemical/petrochemical wastes, with similar properties as those from import having decreased prices an that affect as small as possible the environment.

Abstract: The present work is part of a more complex study referring to chemical substances known under the name of surfactants” or tensioactive agents” which can alter the conductivity of fibers, textile materials, etc. in order to diminish some negative physiological effects on the human body. The use of raw materials, indigenous or imported, refers to the strategy adopted by each firm, concerning their own technology, which should include both organization and management of production processes, and ways of introducing the technical progress with economic efficiency.

Economia : Seria Management , 2009,
Abstract: The paper analyses how the data envelopment analysis (DEA) and fuzzy set theory can be used to measure and evaluate the efficiency of a hierarchical system with n decision making units and a coordinating unit. It is presented a model for determining the of activity levels of decision making units so as to achieve both fuzzy objectives of achieving global target levels of coordination unit on the inputs and outputs and individual target levels of decision making units, and then some methods to resolve fuzzy models are proposed.

Abstract: Taking carefully into consideration the way in which emerged and evolved the actual economic and financial crisis, in Europe and in Romania, one can conclude that the educational management, as an academic program, or as a scientific research, can provide some solutions. First are analyzed the initiatives taken by the decision factors from the superior European education, in 1999, before the breaking out of the crisis, through the Bologna Convention. Due to the educational management's particularity to establish a communication channel between academics, specialists in educational sciences, educational institutions managers and political leaders, are presented the beneficial effects which a number of decisions like the stimulation of young people's interest for the studying of economical and entrepreneurial sciences, systematic programs open socially and culturally of knowing the foreign languages, the analysis of career's dynamic in parallel to the modernization of the career education, could have.

Abstract: Many of Xenopol’s studies, articles and economic papers fully prove his permanent interest in this area, so important for the life of a country.. This fact urged him to look into the economic state of his people, to search for its causes and formulate solutions, some of them among the most realistic ones, for its improvement, for the reduction of the gap that separated us from the most economically developed countries
