having different evaluations of economic and social results. This represents the most complicated case of assessment which lmpl les simultaneous comparison and evaluation of variants by different Indicators measured by different units. In such a case one utilizes various approaches and methods of evaluation either by bringing the social result to value measuring unit or by model levelling of compared variants by one of the directions of obtaining the desired effect while selecting the best variant by the other. While using the first approach it Is necessary to have a set of Indicators making It possible to present all multlpl !city of social results of new technology or scientific achievements as economic results. Besides. It Is necessary to elaborate methods and means of transforming physical social Indicators into economic Indicators. This problem Is highly compl lcated and at present It Is solved mainly through expert evaluation, analogy method, social Inquest and statistical methods. In the second approach a certain standard level of social results which can be attained with a given type of technological Innovation Is set. Then alI compared variants of this Innovation are hypothetically brought to this level accompanied by calculation of total reduced costs of creating of new technology prototype and bringing It to the desired level In all variants at other conditions being equal. The best variant is selected on the basis of minimum costs. The notion of "damage" Is widely used In many approaches and methods of economic assessment of social effects of new technology. Especially It Is widely used In economic assessment of S and T progress effects on ecology. On the one hand, every new type of technology should be assessed from the point of view of Its damage to the environment, and, on the other ha~d. various Innovations Improving environment protection qualities of new 
**Analysis**
The text discusses the evaluation of social and economic results of new technologies and scientific achievements. It highlights the complexity of assessment and proposes various approaches and methods to compare and evaluate different variants. The text also mentions the concept of "damage" in the context of environmental impact. Based on this, it can be inferred that the text is related to the evaluation of the consequences of technological advancements, which is a key aspect of the Science and Technology category.
