       Improving the methodology for assessment of the "quality of life" (QoL) of patients in ophthalmic practice is a regular process aimed at increasing the efficiency of clinical diagnostic examination. An analysis of how the quality of life assessment methodology is being improved in the practice of foreign ophthalmologists reveals two interrelated areas — the introduction of various methods of mathematical analysis in order to confirm the content and constructive validity of the developed questionnaire, as well as the wider distribution of approved questionnaires based on adaptation to a specific state language. The accumulated experience of the authors indicates that the involvement (as experts) of ophthalmologists in the development of a QоL questionnaire, as well as the optimal procedure for scaling patient responses, are effective ways to improve the methodology for assessing QoL, which is confirmed by an assessment of the original QoL questionnaires designed for patients with vitreoretinal pathologies, computer vision syndrome and cataracts.   Совершенствование методики оценки «качества жизни» пациента (КЖ) в офтальмологической практике является закономерным процессом, направленным на повышение эффективности клинико-диагностического обследования пациента. Анализ совершенствования методики оценки КЖ в практике зарубежных офтальмологов указывает на два взаимосвязанных направления: внедрение различных методов математического анализа с целью подтверждения содержательной и конструктивной валидности разработанного опросника и более широкое распространение апробированных опросников на основе адаптации к конкретному государственному языку. Накопленный авторский опыт указывает, что привлечение (в качестве экспертов) врачей-офтальмологов к разработке опросника КЖ, а также оптимальная процедура шкалирования ответов пациента являются эффективными направлениями совершенствования методики оценки КЖ, что подтверждается проведенной оценкой оригинальных опросников КЖ пациента при витреоретинальной патологии, компьютерном зрительном синдроме и катаракте

    Proces stvaranja novčanica je dugotrajan i složen, što rezultira kompleksnim rješenjima koja predstavljaju pravo remek djelo grafike. Novčanice su prožete brojnim detaljima i prenose različite informacije koje se analiziraju u teorijskom dijelu rada. Prvotno se postavljaju kriteriji po kojima se izrađuje detaljna analiza velikog broja zaštitnih i konceptualnih elemenata na primjerima novčanica. Time je prikazan okvirni povijesni pregled razvoja novčanica i utjecaji kojima je bio izložen. Analizira se međuovisnost dizajna o sigurnosnim značajkama, te se ispituje razina informiranosti javnosti o zaštitama na novčanicama. Zaključuje se koje metode zaštite su najučinkovitije, te kako šira javnost najčešće provjerava autentičnost novčanica. U eksperimentalnom dijelu rada se na temelju donesenih zaključaka iz teorijskog dijela izrađuje prototip novčanice koja je u najvećoj mjeri prožeta individualiziranim PostScript programskim rješenjima elemenata linijske grafike (rozete, mikrotekst, zaštitne linije, brojevi apoena), a od ostalih zaštita modeliran je individualizirani raster transformacijom matematičkog izraza u PostScript programski kod. Sve ostale zaštite tipične za novčanice simulirane su alatima za rastersku i vektorsku grafiku. U radu se ispituje utjecaj kompozicije zaštitnih elemenata na prepoznavanje autentičnosti novčanica, te efikasnost samih individualiziranih programskih rješenja

    Рurpose. Evaluation of the clinical efficacy of the original procedure for fixing the posterior chamber intraocular lens (IOL) after phacoemulsification of cataracts (FEC), complicated by the violation of capsular lens support.Patients and Methods. 194 patients were examined after FEC,  complicated by a capsular lenticular impairment. They were divided  into 3 groups. In the main group (OG, 64 eyes) the IOL was sutured  with an original technique, fundamentally different method, there  nodes formed at the ends of the filaments were fixed in the layers of the cornea. In 2 controls groups, there the traditional IOL under  the scleral flap (K1, 68 eyes) was performed and the IOL was  attached to the iris (K2, 62 eyes). A comprehensive examination of  the patients’ vision state included an evaluation of clinical, functional and subjective indicators.Results. The lowest total probability of postoperative complications development was noted in OG (6.4%) compared to K2 and K1  (16.0–17.7%). The overall probability of changing the positions of  the IOL in the exhaust gas is 6.4%, which is significantly lower than  in the K2 (9.6%) and K1 (14.6%) groups. The developed method in  comparison with the traditional methods of fixation provides a higher level of patient’s quality of life (by 10.2–11.7%, p < 0.05)  and functional indicators associated with the brightness and contrast sensitivity of the eye.The conclusion. The developed technique provides, in comparison with the traditional, a higher level of safety and functionality of IOL fixation
