Formation and development of the language training methodology for foreign students at classical universities. Part 3. Teaching the Ukrainian language

The article is another part of a series of scientific and methodical studies on the formation and development of language training methods for foreign students at classical university. Previous research has analyzed the formation of the conceptual foundations of language training of educational migrants of various study profiles, the history, principles, and features of language education of students of higher education of non-linguistic and philological specialties based on the activity of the Language Training Department 1 of V. N. Karazin Kharkiv National University. The third part is devoted to the analysis of problems and achievements of the department in teaching Ukrainian as a foreign language. The gradual transition to teaching the state language was carried out from the end of the 90-s of the XX century. This required a rethinking of methodological approaches and principles, the development of principles and provisions of the methodology of teaching Ukrainian as a foreign language, and educational and methodical support of the teaching process. The research tools of the article as a part of the series are the method of systematic analysis of the scientific work on the linguistic problems of the Ukrainian language done by the department’s specialists, characteristics of dissertation studies, scientific publications, didactic work, and their methodical implementations. The main stages of the formation of the methodological foundations of teaching Ukrainian as a foreign language at classical university, the optimal methods of teaching language aspects, the formation of speech activity skills, the intercultural communication are also highlighted in the paper. The authors defined the main scientific and methodological principles and components of the educational process organization (in particular, the development of the program as one of the main factors in the creation of methodical and informational support for language training of foreign students studying at Ukrainian universities). The authors relied on the concept of language education of foreigners presented in the first article of the series, the structure of the modern educational paradigm, analysis of the influence of the competence approach on curricula creation, and professionally oriented language training of foreigners. The article also contains an analysis of some educational and methodical Ukrainian language guides and manuals that have been used for forming components of communicative competence of educational migrants during language acquisition in a new social-cultural environment, in the academic space of a Ukrainian classical university.

Choreographic Culture of Ukraine in Scientific Research in 2017–2021: Analysis of Main Directions

The purpose of the article is to analyse a number of dissertation studies that have actualised the cultural problems of the Ukrainian choreographic culture development. The research methodology is based on the use of scientific research methods, such as analysis, synthesis, and generalisation. The possibilities of a personalised approach to the study of choreographic culture are emphasised, thanks to which the theoretical aspects and practical experience of Ukrainian scientists are outlined. The scientific novelty of the work consists in the systematisation of scientific research conducted in recent years in the field of choreographic culture of Ukraine. Conclusions. The topics of dissertation research in recent years have revealed noticeable trends in the study of theoretical issues and practices, namely the formation and development of Ukrainian choreographic culture of the 20th-21st centuries, folk choreographic art as a carrier of ethno-cultural identity (I. Klymchuk), transformational processes of Ukrainian folk choreography (V. Lytvynenko), and the phenomenon of virtuosity in Ukrainian folk-stage dance (A. Morozov). Significant are the studies that focus on the regional and stylistic features of the folk choreographic culture of Ukraine (V. Hordeev, O. Kvetsko, I. Mostova, A. Pidlypskyi, A. Tymchula, L. Shchur). A noticeable segment in modern scientific research belongs to the problems of ballet art, which organically combines folk and classical dance, having a practical reflection in performances of national themes, the use of national artistic images, as well as consideration of the creative activity of ballet masters and ballet dancers of Ukraine. Key words: culture, Ukrainian choreographic culture, folk choreographic art, ballet art, folk stage dance, classical dance.

СУЧАСНА ЗАРУБІЖНА КОНСТИТУЦІОНАЛІСТИКА: ІНСТИТУТ ПОРІВНЯЛЬНОГО ПУБЛІЧНОГО ПРАВА ТА МІЖНАРОДНОГО ПРАВА ІМЕНІ МАКСА ПЛАНКА (MAX PLANCK INSTITUTE FOR COMPARATIVE PUBLIK LAW AND INTERNATIONAL LAW)

The European vector of modern Ukrainian politics involves a broad and thorough acquaintance with the latest achievements of European and world legal thought. Domestic jurisprudence, which has been developing for many years in line with the orthodox Marxist methodology, overcomes not only ideological isolation, but also produces a new research culture based on the study and understanding of modern trends in foreign jurisprudence. It is necessary to emphasize that this process is only unfolding and is not always implemented in specific studies, in particular, dissertation studies, where the use of works by foreign authors on the studied issues is often absent, and, therefore, the latest methodological approaches and theoretical and doctrinal developments of the world's leading experts are not taken into account. As before, little information is published in domestic legal periodicals about foreign research centers and schools in various fields of law, activities of foreign legal scholars, academic publishing houses and authoritative periodicals. All this fully applies to our science of constitutional law, which encourages us to more actively cover the study of constitutional law in foreign countries, publishing activity and activities of scientific centers related to the problems of constitutional law. One of the internationally recognized centers of modern constitutional studies is the Max Planck Institute of Comparative Public Law and International Law (Heidelberg, Germany). His research in many respects sets the tone and determines the direction of modern constitutional and legal investigations. The article provides a detailed description of the work of the Institute, which is built on the principles of theoretical and methodological pluralism, individual projects are specifically directed to the use of different methodological approaches. It is noted that the research is conducted in two forms: 1) doctrinal and theoretical analysis - problem-oriented fundamental research that seeks to reveal the structures, development and regularities of constitutional and international law; 2) systematic analysis and comparison of legal norms in order to solve current legal problems or carry out reforms. The relatively low level of abstraction of such studies is explained by the need to provide specific recommendations to officials or practicing lawyers. The institute strives for broad relations with the public. It is noted that the Institute occupies a leading position in world constitutionalism in terms of the volume of research conducted, the wide coverage of topics and the depth of theoretical analysis. His achievements must be taken into account by the domestic science of constitutional law.

Medical PhD Programs in Ukraine through the Prism of Accreditation and Licensing: Candidate of Medical Science or PhD in Healthcare

The first defence of dissertation studies for obtaining the scientific degree of Doctor of Philosophy (PhD) in Ukraine took place in 2019. As of November 1, 2022, 51 institutions are conducting PhD training in Ukraine's speciality 222 "Medicine". The total licensed amount of PhD training in the speciality 222 "Medicine" is 4,784 places. Still, the number of applicants who obtain the degree of Doctor of Philosophy is three times lower - 33% of the licensed amount (1,575 applicants). As of November 1, 2022, 120 applicants (8%) studied under non-accredited educational and scientific programs in the speciality 222 "Medicine".

Predictors of dissertation publication in clinical and counseling psychology.

A doctoral dissertation constitutes a student's original research and a novel contribution to scientific knowledge. Yet, few psychology dissertations, particularly in professional subfields, are published in the peer-reviewed literature, and the reasons for this are unclear. The present study investigated student, advisor, and doctoral program variables that might predict dissertation publication in professional psychology. Using a stratified random cohort sample of 169 Ph.D. dissertations in clinical and counseling psychology, we conducted exhaustive searches to determine whether dissertation studies were published in peer-reviewed journals within 0-7 years following their completion. Logistic regression models were estimated to test whether dissertation publication was predicted by student and advisor prior research productivity, dissertation length, and doctoral program's training emphasis, accreditation status, and subfield. Results indicated that dissertations that were supervised by more research-productive advisors and that were relatively brief (<180 pages) were significantly more likely to be published in peer-reviewed journals. No other predictors were significant. Results are discussed with regard to implications for training and mentorship. Faculty advisors who publish frequently might be more likely to attract research-oriented students, to mentor students in preparing a publishable dissertation, and/or to encourage students to publish their dissertation research. By systematically promoting research dissemination as part of doctoral research training, graduate programs and faculty mentors in clinical and counseling psychology could help facilitate students' sharing their dissertation findings with the scientific community.

First dissertation in medical geography at the Medico-Surgical Academy

Little-known scientific facts related to the circumstances of writing and defending the dissertation for the Medico-Surgical Academy Eduard Blaschke entitled "Medical topography of the Novo-Arkhangelsk port, the main Russian settlement in North America were considered. Medical topographic descriptions of various territories and settlements of the Russian Empire were numerous in the 18th19th centuries, but dissertation studies of this kind are rare. The authors of the article carried out a bibliographic work covering a wide range of reliable sources in order to identify the earliest dissertation research in the field of medical geography. According to updated information, E. Blaschkes work stored in the library of the Kirov Military Medical Academy was the first scientific work in the history of the Medical and Surgical Academy in the field of medical geography, presented as a dissertation for the degree of Doctor of Medicine. The dissertation was written based on E. Blaschkes materials and stay in the Russian colonial possessions in North America as the head doctor of the Novo-Arkhangelsk Hospital. Local living conditions, lifestyle, occupation, and nature of work and leisure of the population were systematically described, and as a result, due to all these reasons, since endemic diseases can be associated not only with climatic causes the endemic specificity of the incidence of the inhabitants of this region, and with a wider range of local territorial factors. E. Blaschkes medical-geographical research was of great scientific and practical importance for its time. It was timely and relevant, but today this work is not known to a wide range of specialists, which, of course, has a significant gap in the knowledge of the history of the formation and development of medical geography, which needs to be replenished. The historical research conducted by the authors of the article allows us to highly appreciate the role of graduates of the Medical and Surgical Academy in healthcare systems organization in the Russian colonial possessions in America: all the chief doctors of the central hospital of the settlements were its graduates. Of particular interest is the experience of E. Blaschke in combating the smallpox epidemic in the Aleutian Islands and the local populations mass vaccination.

THE METHOD OF FORMING THE NEED FOR PHYSICAL SELF-IMPROVEMENT OF STUDENTS OF HIGHER EDUCATION INSTITUTIONS OF UKRAINE

The article, based on the analysis of sources, defines and analyzes the need for physical self-improvement of student youth, namely: the structure and main components of this need have not yet been fully disclosed; the method of step-by-step application of means and methods in forming the need for physical exercises has not been developed; methods of interest formation and motives of independent physical exercises are not sufficiently researched. It is noted that the professional training of student youth cannot be complete if it is limited only to mastering knowledge in the specialty, an indispensable requirement for the successful training of students of higher education in Ukraine is the mandatory availability of physical capabilities for each student to use their knowledge as efficiently as possible in future professional activities.&#x0D; The analysis of literary sources and dissertation studies shows that the problem of forming the need for physical self- improvement is just beginning to be developed. Until now, the concept of "need for physical self-improvement" has not been clearly defined, the structure and main components of this need have not been revealed, the methodology for the step-by-step application of means and methods in the formation of the need for physical exercises has not been developed, the means and methods of forming interest and motives for independent exercises have not been sufficiently researched physical exercises.&#x0D; The purpose of the article is to theoretically substantiate and experimentally verify the effectiveness of the method of forming the need for physical self-improvement among students of higher education institutions of Ukraine. Principal results. It is proved that the three-component program of formation of the need for physical self-improvement of future specialists proposed by the author covers all aspects of physical education and allows it to act as a fundamental process of forming a students’ physical culture, when the valuable components of this sphere of culture become for them an internal asset and an objective vital need.

To the question of the modern structure of a separate forensic methodology

The article analyzes the structure of the forensic method of investigation of certain types of crimes, proposes its modern structure, in particular, a separate forensic method must necessarily include a forensic characteristic, typical investigative situations and programs (algorithms) of the investigator's actions in each judicial investigation. stages of the investigation, specifics of the tactics of individual investigative (search) actions, other measures and tactical operations, as well as specifics of the investigation under martial law.&#x0D; Forensic characterization is considered as an important structural unit of a separate methodology, which reflects its purely forensic aspect, describes forensically significant, statistically derived features of crimes of a certain group. The author comes to the conclusion that forensic characteristics include signs of circumstances that are subject to proof (but not all), but only those signs that determine the choice of appropriate forensic means, techniques and methods of crime investigation (forensically significant). Therefore, he claims that the refusal to study the circumstances to be proven in the methodology and in most of the modern dissertation studies in criminology will be justified.&#x0D; Based on the analysis of existing scientific views and concepts, the author substantiates the position of highlighting the initial stage of the investigation, as well as the feasibility of developing recommendations for the organization of the investigator's actions at this stage and in the investigation process at two traditional stages. forensic stages: initial and subsequent. Based on a comparison of a specific investigative situation that arose during the investigation of a specific crime with a typical one, investigators should choose the appropriate, most effective forensic means and methods of establishing objective reality.&#x0D; The inclusion in the structure of a separate forensic methodology of investigation features under martial law is considered as an urgent need of practical workers. After all, the conditions of martial law make changes both in the program (algorithm) of the investigator's actions and in the tactics of conducting investigative (search) actions. This is due to the fact that the legislator departed from the principle of immediacy of the research of evidence.&#x0D; It is noted that the study of other forensic aspects of the investigation of certain types of crimes may take place.

Socio-psychological portrait of a modern schoolchild

Introduction. The relevance of studying the socio-psychological characteristics of modern children and adolescents is associated with the processes of globalization, informatization, digitalization of modern society in relation to the education system in general and the personality of a modern schoolboy in particular. In this article, an attempt is made to present a socio-psychological portrait of a modern schoolboy, to determine the role of a teacher in the digital educational environment, as well as the possibilities of his professional and personal growth in the conditions of digitalization by analyzing and systematizing the results of theoretical and experimental research on the problem.Materials and Methods. This article uses an analytical approach to the consideration of modern domestic and foreign studies, which allows to identify the positive and negative sides of the digitalization of the modern education system. We focused on scientific articles, monographs, teaching aids, dissertation studies containing the results of theoretical and experimental studies of various aspects of this problem.Results. As the analysis of the literature has shown, the studies of foreign authors widely cover this problem from the perspective of the "theory of generations", while domestic research is largely based on the methodology of domestic psychology. In the Russian psychological literature, a number of studies are devoted to the study of the socio-psychological characteristics of modern adolescents, in particular, the system of value orientations, attitudes to educational activities, socialization, including using social networks, adaptability to the conditions of the educational environment, but such studies are insufficient due to the complexity of the studied issues and the constantly changing conditions of the social life of a modern student.Discussion and Conclusions. The discussion of issues related to the socio-psychological characteristics of a modern schoolboy in the conditions of digitalization of the system of national education invariably rests on the need to find forms, methods, means of organizing effective school education and assumes that teachers of the general education system have a minimum of psychological knowledge about age and individual psychological patterns of the development of the psyche of a younger schoolboy and a teenager, the formation of his personality.

Development of the Methodology of Early Foreign Language Teaching in Modern Research

The article describes the results of the research, revealing the analysis of dissertation research devoted to two areas: firstly, the problems of teaching foreign language methods, and secondly, the problems of teaching and educating preschool children. The purpose of the research is to determine the ways of developing the methodology of early foreign language teaching. As a result, a quantitative and qualitative analysis of 123 dissertation studies on scientific specialties 13.00.01 General pedagogy, history of pedagogy and education, 13.00.02 Theory and methodology of teaching and upbringing (by fields of education), 13.00.08. Theory and methodology of vocational education, for the period from 2012 to 2021, that allow to determine the main directions of the methodology development of early foreign language teaching. The question of the interdisciplinary orientation of the works is considered. Scientific developments are devoted to the methodology of early teaching foreign languages, in particular, the integration of foreign language education in the process of education of value orientations, moral education, intellectual development, the development of speech communication. It is concluded that most studies in the field of foreign language teaching methods are devoted to the formation of language sub-skills, speech skills, and the formation of competencies, however, they are focused on school-age students, adult learners. Insufficient attention is paid to the methodology of early learning of foreign languages; despite the fact that many local and foreign researchers believe that preschool children are ready for foreign language learning. Dissertation research is devoted to education and upbringing of preschool children studies aspects such as the formation of cognitive interest, development of socio-personal qualities, formation of emotional and moral guidelines, study of general pedagogical principles that contribute to the development of preschool children, that is, first of all, pedagogical aspects, while methodological aspects of teaching a foreign language are integrated into the process of upbringing a child.

IMPROVING THE MECHANISMS OF REGULATORY AND LEGAL REGULATION OF HOME EDUCATION IN UKRAINE

The article deals with one of the important problems of improving the mechanisms of regulatory and legal regulation of home schooling and ensuring the quality of home schooling, the implementation of the «New Ukrainian School». The legislative framework and scientific literature on defining the concepts of «home education», «normative and legal framework», and «mechanisms» have been analyzed. Acquiring education in the family (home) form is possible for persons under the age of 18, whose parents have expressed a desire to organize the educational process independently, taking into account the abilities, interests, needs, motivation, opportunities and experience of their children, to ensure their individual pace of acquiring education. The requirements that orient the teacher and parents to the use of home education, adequate level of development of modern technologies are disclosed. The features that characterize the priorities and components of educational activity that best provide home (family) education are determined. The purpose of the article is to develop the implementation of modern approaches to the problems of improving the mechanisms of normative and legal regulation of home education. The publication analyzes the problems and prospects of home schooling in Ukraine. Dissertation studies of Ukrainian and foreign scientists devoted to the development of state administration in the field of family education were analyzed, methodological and methodical approaches to the formation of strategic mechanisms of state administration in the specified area and a new approach of state policy were determined. The main direction of further research should be the disclosure of the content and nature of modern transformations of the state administration system, the introduction of information space regarding legal issue the sphere of family education (homeschooling) in our country, the outline of modern trends and prospects for the development of state management of family (home) education at the regional level. The following research methods are used in the article: the method of theoretical and practical direction. s in recent years, the dissemination of information on the identification of priority directions for reforming.

THE GENESYS OF LEGAL AND STRUCTURAL SUPPORT OF THE STATE CULTURE MANAGEMENT IN UKRAINE

The article considers sphere of cultural sphere development at the level of state management, besides, the state program of economical and social development in Ukraine, the programs of the Cabinet of Ministers of Ukraine, the target programs in the spheres of culture during the times of the State independence. It is also mainly focused on comparative historical analysis of the cultural content and organizational and legal support of culture state management on the territory of Ukraine. The main problems of regulatory, legal and financial support for the cultural development in the conditions of transformational changes are revealed. The essence of the concepts «state administration», «sphere of culture», «culture» is highlighted. The problems of state management in the cultural sphere in the social, spiritual, humanitarian, and organizational aspects were studied, and the cultural sphere was defined as an integral component of the full­fledged development of the individual and society as a whole. Culture itself is the basis for each citizen self­identification and is remains the significant lever of state policy providing its contribution to the development of the national outlook. Modernization in the cultural sphere of Ukraine will allow to effectively form Ukrainian cultural values as an investment to the future of the State. Today, the sphere of culture is integrated into all aspects of social life, economy and politics, which specifies the urgency of the reform direction determination, requires certain shifts in the state regulation of the cultural sphere in Ukraine. Dissertation studies of Ukrainian scientists devoted to the development of state management in the sphere of culture were analyzed. Methodological and methodical approaches to the formation of strategic mechanisms of state management in the specified sphere and the reformation potential of the state’s cultural policy were determined. The main direction of further research should be the transformational reform content and nature disclosure of the state management system in the field of culture during the period of Ukrainian independence, the determination of priority directions for reforming the sphere of culture in our country, modern trends and prospects for the development of state culture management at the regional level.

A Review on Federated Learning and Machine Learning Approaches: Categorization, Application Areas, and Blockchain Technology

Federated learning (FL) is a scheme in which several consumers work collectively to unravel machine learning (ML) problems, with a dominant collector synchronizing the procedure. This decision correspondingly enables the training data to be distributed, guaranteeing that the individual device’s data are secluded. The paper systematically reviewed the available literature using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guiding principle. The study presents a systematic review of appliable ML approaches for FL, reviews the categorization of FL, discusses the FL application areas, presents the relationship between FL and Blockchain Technology (BT), and discusses some existing literature that has used FL and ML approaches. The study also examined applicable machine learning models for federated learning. The inclusion measures were (i) published between 2017 and 2021, (ii) written in English, (iii) published in a peer-reviewed scientific journal, and (iv) Preprint published papers. Unpublished studies, thesis and dissertation studies, (ii) conference papers, (iii) not in English, and (iv) did not use artificial intelligence models and blockchain technology were all removed from the review. In total, 84 eligible papers were finally examined in this study. Finally, in recent years, the amount of research on ML using FL has increased. Accuracy equivalent to standard feature-based techniques has been attained, and ensembles of many algorithms may yield even better results. We discovered that the best results were obtained from the hybrid design of an ML ensemble employing expert features. However, some additional difficulties and issues need to be overcome, such as efficiency, complexity, and smaller datasets. In addition, novel FL applications should be investigated from the standpoint of the datasets and methodologies.

The Application of Particle Swarm Optimization in Neural Networks

The birth of the neural network model has provided a technological platform for the development of various industries. Among them, the branch network scientific research management model represented by the scientific research field is particularly profitable. China’s traditional research management system has been unable to meet the requirements of the present era and the management system reform is imperative. Therefore, based on Particle Swarm Optimization (PSO), this dissertation studies the neural network model based on the prerequisite that the branch network research management system retains the advantages of the traditional model. It tracks the optimal value of current search through cross and mutation. The optimal solution value is finally determined by solving the relationship between particle weight and inertia weight. In the final test, we establish the feasibility of the program.

The Super-vision of Autoethnographic Dissertation Studies: Transformative Stories of the Supervisor and the Supervised Revealed

The purpose of this paper is to explore the super-vision of dissertations, from the perspective of the supervisor and two supervisees who did dissertations that had an evocative autoethnographic component. We argue that autoethnography in context of scholarly writing encourages both an inner looking, and an outward looking that results in a super-vision, that is the result of the relationship between the supervisor and the supervisee, which evokes further insights, analysis, and reflexive stories.

Academician Nikolai Nikolaevich Petrov (1876–1964) (on the 145th anniversary of his birth)

Nikolai Nikolaevich Petrov was born on December 2 (14), 1876 in St. Petersburg in the family of a famous scientist, professor of mechanics Nikolai Pavlovich Petrov. In 1894, Nikolai graduated from the First Classical Gymnasium and entered the Imperial Military Medical Academy. After graduation in 1898, Nikolai Nikolaevich was left at the Academy for 3 years to prepare for a professorship at the Department of Surgical Pathology, and in 1902 completed his dissertation experimental work for the degree of Doctor of Medicine on the topic: «Tuberculosis of the joints due to injury». After defending his thesis, he was sent for 2 years to further improve in Western Europe, and after returning to St. Petersburg in 1905, N. N. Petrov was elected to the position of privatdozent of the Military Medical Academy. From 1905 to 1912, Nikolai Nikolaevich published about 40 scientific papers, including two fundamental monographs: «The General Doctrine of tumors (pathology and clinic)» (1910) – the first monograph in Russian devoted to oncology, and the monograph «Free Bone plastic Surgery», published in 1912. From 1912 to 1913, he was the Professor of the Hospital Surgical Clinic of the University of Warsaw. From 1913 to 1964, he was the Professor of the Surgical Clinic of the State Institute for Advanced Medical Training. In 1920, N. N. Petrov took an active part in the creation of the first university in the Kuban, especially in the organization of the Faculty of Medicine in Krasnodar. In 1917, N. N. Petrov was elected to the position of the Head of the Department of Hospital Surgery of the Women’s Medical Institute (later the Pavlov First Leningrad Medical Institute, and now the Pavlov First Saint Petersburg State Medical University (Pavlov University)), which he headed until 1927. Due to the duty trips, he began to head the Department only in 1921 after returning from the front. In 1921, N. N. Petrov and his family returned to Petrograd. Thanks to the perseverance and high authority of Nikolai Nikolaevich as a surgeon, scientist and health organizer, he managed to achieve the creation of a specialized practical and research oncological center in Leningrad, and on March 15, 1927, the Institute of Oncology was founded, which in 1966 was named after N. N. Petrov. Nikolay Nikolaevich made a significant contribution to the development of experimental oncology thanks to the organization in 1938 of the laboratory of experimental cancer in Sukhumi on the basis of a nursery for monkeys, which was at that time a branch of All-Union Institute of Experimental Medicine (VIEM). Nikolay Nikolaevich was the author and co-author of more than 300 scientific papers, more than 50 dissertation studies were carried out under his supervision. His most famous student was F.G. Uglov, who headed the Department of Hospital Surgery of the Pavlov First Leningrad Medical Institute in 1950. For outstanding services to Soviet healthcare and great achievements in medical science, N. N. Petrov was awarded three Orders of Lenin and two Orders of the Red Banner of Labor. Academician Nikolai Nikolaevich Petrov died on March 2, 1964 and was buried at the cemetery in the village of Komarovo near Leningrad.

Delay-probability-dependent state estimation for neural networks with hybrid delays

This dissertation studies the delay-probability-dependent H∞ state estimation issue of neural networks (NNs) with hybrid delays. First, more general system model and state estimator are established by considering discrete delay, distributed delay and probability distribution of time delays. Second, a innovative Lyapunov-Krasovskii functional (LKF) containing augmented non-integral and single-integral quadratic terms is put forward, which can inflect internal connections of multiple functional terms. Meanwhile, in order to handle the infinitesimal operators of LKF effectively, generalized free-weighting-matrix integral inequality (GFWMII) is chosen to cooperate with wirtinger-based inequality. As a consequence, less conservative criteria are obtained, which ensure that the considered system is asymptotically mean-square stable with a desired H∞ performance. Finally, two simulated examples are displayed to bring out the advantage of the achieved approach.
