The occurrence of physiological artifacts generated by eye movements in electrical brain activity (electroencephalography, EEG) is a well-known problem in clinical practice. In order to increase the accuracy of the detection of eye movements during EEG examination, additional electrooculogram channels (electrooculography, EOG) with a standard PC keyboard are used. The EOG technique is not always comfortable for patients. Another issue is that the use of EOG channels in the EEG examination leads to the prolongation of time required for patient preparation. To solve these problems, we developed a new peripheral device suitable for the indication of common ocular artifacts in EEG. The obtained differences between the recommended methods (i.e., EOG, PC keyboard) and our new device have been presented using RMSE (root mean square error). The presented equipment can be used either during EEG examination or after registration of EEG signals in order to indicate the ocular artifacts. Furthermore, this device is compatible with the EEG software used in clinical practice.

In every language a twofold process could be observed: 1) a huge surge of new terms and 2) a big part of these new terms make their way into the common language. The nucleus of the vocabulary and the grammatical system of the common language make the essence of a language and its national originality. Because of such an intensive development in the future terminological lexis can become a basis of a common language and it ought to be not a spontaneously formed sum of terminological lexis, but an entirety of consciously created terms, which meet the requirements of language, logic and terminology. Computer terminology, by comparison with terminology of other fields, is being created in a slightly unusual way. The first computation institutions in Lithuania were established in early sixties and a decade later there were a few computation centres and a number of key-operated and punch machines working. Together with the new computational technology many new devices, units, parts, phenomena and characteristics appeared, which needed naming. Specialists faced an obvious shortage of Lithuanian terms for computing equipment. In 1971 this gap was partly filled by „Rusų-lietuvių-anglų kalbų skaičiavimo technikos žodynas“ (Russian-Lithuanian-English dictionary of computing equipment), which for a long time (for more than 20 years) was the only one terminological dictionary of this field. Only during nineties a few dictionaries of different scope appeared. Computer terminology from ten dictionaries, which are presently available, shows that 35 year period of computer terminology is a stage of its creation, the main features of which are reasonable synonymy (when both international term are being used to name the concept) and variability. Such state of Lithuanian computer terminology is predetermined by some linguistic, interlinguistic and sociolinguistic factors. At present in Lithuania terminological dictionaries of various fields are being given to the State Commission of the Lithuanian Language for its approval. The regulations of the evaluation of terminological dictionaries suggest two-level approbation. If terms are systematized and normalized to a satisfactory level, on the title page of the dictionary there is an inscription “The State Commission of the Lithuanian Language does not object”. If terms are systematized and normalized very well, the value of the most of terms is proven by the longer usage and the ratio of Lithuanian and borrowed terms is acceptable, the dictionary gets an approbations “The State Commission of the Lithuanian language approves”. All terminology dictionaries have an approbation of the first level. Thus doubts should arise concerning the needs of such an approbation.

Kiekvienoje kalboje reiškiasi dvilypis procesas: 1) didžiulis naujų terminų antplūdis ir 2) dalies tų naujų terminų skverbimasis į bendrinę kalbą, kurios leksikos branduolys ir gramatinė sandara sudaro kalbos esmę, jos nacionalinį savitumą. Dėl tokios intensyvios raidos termininė leksika ateityje gali tapti bendrinės kalbos pagrindu, kuris turėtų būti ne stichiškai susidariusi termininės leksikos (terminų, terminoidų, kvaziterminų ir pan.) visuma, bet sąmoningai sukurtų terminų, atitinkančių kalbos, logikos, terminologijos reikalavimus, visetas. Kad to neatsitiktų, kiekvienos mokslo srities terminija turėtų būti nagrinėjama mikrosistemomis. Straipsnyje pateikta pagrindinių kompiuterijos terminų, t. y. kompiuteris, aparatinė įranga, programinė įranga, mikrosistemos raidos apžvalga. Analizės šaltinis - kompiuterijos žodynai.
