On the theory of information needsThe rapid development of modern information and cognitive technologies prompts to revision of the theoretical basis of the information processes communication. The theory of information needs is one of the recent. The rather general approach to information needs is addressed in the article.

Development and application of the generalized functional model of one-stage chemical manufacturingOne of the approaches of chemical manufacturing information support is model-driven engineering
which focuses on the abstract representation of the knowledge as the domain model. From one
side, domain models are intuitive and user-friendly for the expert. From the other side, such models
are formal and can be translated to software constructions. The IDEF specifications are used for the
model definitions creating. First, we provide the generalized functional model on the basis of informal
descriptions of one-step chemical manufacturing. We begin with top-level context diagram to specify
the main inputs, outputs, controls and mechanisms of the chemical manufacturing. From this diagram
the derived diagram is generated. The derived diagram describes the sequence of base technological
steps such as row materials preparation, chemical transformation, product refinement and condensate
separation. The quality inspection is added to the end of the sequence. Feedback arrows present recycles
of raw materials. Then the implementation of this model for the production of methyl tertiary butyl
ether is described. The detailing of the generalized model means naming of functional blocks and
arrows while the model structure does not change. So the generalized model can be treated as a template
for any chemical one-stage manufacturing model.
