A Novel Flag-Language Remote Control Design for a Laparoscopic Camera Holder Using Image Processing
Kateryna Zinchenko,Wayne Shin-Wei Huang,Kai-Che Liu,Kai-Tai Song 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10
Minimally invasive surgeries(MIS) possess obvious advantages for patients but require more specially trained personnel than common, open procedure. With modern advances in robotics, it becomes possible to ease these requirements by introducing robotized assistants into operation. However, for robot-assisted solo MIS, it is crucial to have appropriate methods for robot control. This work presents a design of flag language as a novel human-to-robot communication method based on image processing of the endoscope video during real-time intervention. The proposed system comprises autonomous positioning of endoscope holder combined with recognition of surgeon intention by analyzing surgical instrument postures. The proposed algorithm has been evaluated using experimental setup as well as video clips from laparoscopic operation. Experimental results show that the flag posture can be detected satisfactorily with speed of 12 frames per second, as well as system robustness under moderate lighting and noise conditions.

Pleural Metastasis of Atypical Bronchial Carcinoid
Eugeniy Igorevich Zinchenko,Olga Sergeevna Maslak,Vadim Grigorievich Pischik,Aleksandr Dmitrievich Obornev,Aleksandr Igorevich Kovalenko 대한흉부외과학회 2020 Journal of Chest Surgery (J Chest Surg) Vol.53 No.5
Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management. We report a case of atypical carcinoid with local recurrence and pleural metastases treated by video-assisted thoracoscopic surgery lobectomy and total pleurectomy with photodynamic therapy after non-radical wedge resection.

Background: S tudies on the specificity of ABH antigen-antibody interactions at different pH values are rare. Therefore, the aim of this study was to estimate the effect of acidification of the reacting medium on the agglutinating ability of anti-A monoclonal antibodies (mABs) and their inhibition by glycoconjugates of red blood cell membranes. Methods: Anti-A mABs were obtained from the Fourth International Workshop on Monoclonal Antibodies Against Human Red Blood Cell and Related Antigens (on July 19-20, 2002, in Paris, France). The glycoconjugates were isolated from erythrocytes' membranes. The inhibition of the lipid and protein isotypes of the blood group A antigen was assessed. Results: The acidic medium decreased the agglutinating ability of acid immunoglobulin M (IgM) anti-A mABs, in contrast to alkaline immunoglobulin G (IgG) mABs. Meanwhile, at pH 6.5, IgM antibodies exhibited a high adsorption capacity, while IgG antibodies demonstrated a strong adsorption capacity at an alkaline pH. mABs 2-19, 2-28, 2-22, and 2-8 were inhibited by the acidic lipid and protein glycotopes of erythrocyte membranes. However, mAB 2-8 was inhibited by both acidic and alkaline glycotope variants. Conclusions: The agglutinating and adsorbing abilities of mABs, which are revealed at opposing pH values, should be taken into account during studies of antigen-antibody interactions.

Conceptual Approaches to Training Specialists Using Multimedia Technologies
Shchyrbul, Oleksandr,Babalich, Viktoriya,Mishyn, Sergii,Novikova, Viktoriia,Zinchenko, Lina,Haidamashko, Iryna,Kuchai, Oleksandr International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.9
Modernization of the educational sector requires globalization, democratization, and the transition to an information technology society. The main goal of education at the present stage is to solve the problem of ensuring the priority of the development of education and science. In modern conditions, the quality of training of qualified specialists is becoming particularly relevant. The great role of teacher education is emphasized by its main goal, which is to train specialists who can ensure the versatile and innovative development of a person as a person and the highest value of society, its mental, physical and aesthetic abilities, high moral qualities, and, consequently, the enrichment on this basis of the intellectual, creative and cultural potential of the people. Among the strategic tasks of modernizing higher education is to ensure informatization of the educational process and access to International Information Systems. The essence of the concept of multimedia is clarified. In the context of media education, multimedia lists a number of functions: informational, interpretive, cultural, entertainment, and educational. The need to meet the needs outlined in the article in the conditions of informatization of the educational process requires the teacher to have knowledge and skills in the field of multimedia pedagogical technologies, knowledge of advanced methods and means of modern science. It is considered what relevant concepts of media education have been developed and are being developed in Ukraine and form an important basis for the modernization of education, which will contribute to the construction of an information society in the country and the formation of civil society. Distance learning is considered - the most democratic form of education that allows broad segments of society to get an education. Distance learning methods are used in higher education institutions, in school education, in the system of advanced training of teachers, in the system of training managerial personnel.
