Flipped learning is necessary for modern education but quite difficult to implement. In pedagogical science, the question remains to what extent the practical work of the teacher in combination with the technologies of flipped learning will improve the quality of higher education. The aim of this article is to study the effectiveness and feasibility of using flipped learning technologies, assessing their perception by students (advantages and problems), identified an algorithm for introducing flipped learning technology in higher education institutions. Research methods. The main method is an experiment. An evaluation of the effectiveness of the study was conducted using a questionnaire and observation method. Statistical methods were used to evaluate the results of the experiment. The research hypothesis is that flipped learning allows the teacher to spend more time on an individual approach, to understand the real needs of students, and provide effective feedback, thereby improving the quality of learning and motivation of students, especially while studying complex material. The results of the study are to prove the effectiveness of the technology of flipped education in the study of complex disciplines, courses, topics. The use of flipped learning strategies improves the self-regulation of the educational process, group work skills, improves students' ability to learn, overcome difficulties. The technology of flipped learning in the presence of modern technical means and constant work on improving the level of digital literacy is an effective means for students to master complex topics and problematic issues that require additional consideration and discussion. The perspective of further research is the consideration of integrated approaches to the application of flipped learning technologies to the principles of STEAM-education, multilingual and multicultural programs, etc. It is also worth continuing to develop a set of methods aimed at enhancing the student's learning activities, the formation of group work skills, direct participation in creating the foundations of higher education.

Repressive measures in the Crimea against the Ukrainian media and the ban on the entry of international and Ukrainian monitoring missions created the conditions for the function of providing information to be performed by representatives of civil society. Such a phenomenon was called Crimean citizen journalism and became a post-occupation phenomenon characteristic of the Crimean information sphere. The journalists' activities are aimed at reporting on human rights violations and repression against Ukrainian citizens who find themselves in conditions of information bans and restrictions. Crimean citizen journalism, which connects the peninsula with the mainland of Ukraine, is monothematic in nature, and its emergence has become a form of nonviolent resistance to the occupation of Crimea. The purpose of the study is to cover the characteristic features, the development of common Crimean citizen journalistic movement features as a social phenomenon, a phenomenon that arose after the occupation through the identification of a modern journalist portrait. The study uses the general scientific method of empirical research as the main one, the sociological method of a questionnaire survey, as well as the methods of classification, generalisation, observation, statistical calculation. An analysis of a survey of Crimean citizen journalists demonstrates the existence of an active, mobile community in Crimea that seeks to provide information and human rights nonviolent resistance to the occupation.

This study is on the pedagogical convention of architectural history in Korea, especially that of Western Architecture. Recent institutional change in architectural school in Korea has caused overall restructuring of academic program. In spite of extension in the field of history there was no progress of method and way of thinking. There is no change in the point of view to see the western architecture and its history as a unique and specialized phenomenon in the civilization of mankind. Because of no recognition about for what, for whom, and how to, and because of orientalism, the cultural position of western architectural history and its narrative was not asked. With the help of post-colonialism, de-constructivism and critical historiography this paper tries to show the fundamental premise of western architectural history as a myth and show its prejudice as not being justifiable. The background of the discourse there has been a representation effect with regard to knowledge as a power. we need to escape from this kind of cognitional frame With the analysis of the its premise and narrative we can find it is a historical construct that was made in the age of imperialism. In fact it has a lot of false information and problematic point of view. The Identity and originality of western architecture and its history has no logical reason or foundation if we think that it depends on the difference and comparison with other civilization. For example the explanation of its historical origin western architecture has big difference with Islamic architecture in spite of the resemblance each other. This paper try to show several reasons that discourse of western architectural history can not be survived any longer. So we need to reconstruct new pedagogy with deconstruction for the students of non western, or Korean students. Because it has important effect to see and think about architecture and its history.

본 연구에서는 오픈소스 SW인 Blender를 사용하여 인터넷에서 쉽게 구할 수 있는 3D 프린터용 STL(stereolithography) 파일 기반의 3D 애니메이션을 제작하는 방법을 제시하고 이를 OBJ(Object) 파일과 FBX(filmbox) 파일을 이용하는 경우와 비교하였다. STL 파일은 무료로 제공되는 장점이 있지만 OBJ나 FBX 파일과는 달리 계층 구조(hierarchy), 머티리얼(material) 및 텍스쳐(texture) 정보를 포함하지 않기 때문에 3D 애니메이션 제작과정이 좀 더 복잡해진다. 특히 계층구조 정보의 누락은 3D 애니메이션의 핵심인 리깅(rigging) 작업 시에 원하지 않는 부위가 움직이는 심각한 문제를 발생시키는 원인이 된다. 본 연구에서는 Blender의 웨이트 페인팅 기능을 이용하여 계층구조 누락으로 인한 문제를 해결할 수 있음을 예증하였으며 샘플링 횟수와 해상도가 렌더링(rendering) 시간에 미치는 영향도 함께 조사하였다. 한편 3D 프린터로 출력한 곤충 모형은 초등과학교육에서 새로운 형태의 교육 자료로 활용이 가능할 것으로 기대된다.

The purpose of this study was to investigate significant differences between the application group and nonapplication group of integrated science education in the science class about elementary teachers' perceptions and PCK. The results are as follows. First, no significant differences were found about science teachers' fundamental background variables between the two groups. This results showed that the application of integrated science education didn't have relation with the fundamental background variables. It was found that the application group of integrated science education has a lower frequency than the application group, however, it has been analysed that the application group has been applied at the introduction stage for students' motivation, focused on biology as twice every month. Second, to apply a successful integrated education in the elementary science class, it has analysed that not only teachers should need to understand about application method and concept of integrated science education but also science textbook and teaching-learning material should be developed and diffused in the well-integrated science. Third, it was found that professionality of elementary teachers to teach the scientific content knowledge is not comparatively high and non-application group of integrated science education has a lower PCK than the application group. Therefore, it should be provided that not only training programmes to learn interdisciplinary knowledge related to science, can lead to more understanding about instructional design, teaching strategies and concept for integrated science education should be developed but also chances to participate in various training programmes should be provided to enhance elementary teachers' professionality for integrated science education.

One of the major threats to the stability of classical columns and colonnades are earthquakes. The behavior of columns under high seismic excitation loads is non-linear and complex since rocking, wobbling and sliding failure modes can occur. Therefore, three dimensional simulation approaches are essential to investigate the in-plane and out-of-plane response of such structures during harmonic and seismic loading excitations. Using a software based on the Distinct Element Method (DEM) of analysis, a three dimensional numerical study has been performed to investigate the parameters affecting the seismic behaviour of colonnades' structural systems. A typical section of the two-storey colonnade of the Forum in Pompeii has been modelled and studied parametrically, in order to identify the main factors affecting the stability and to improve our understanding of the earthquake behaviour of such structures. The model is then used to compare the results between 2D and 3D simulations emphasizing the different response for the selected earthquake records. From the results analysis, it was found that the high-frequency motion requires large base acceleration amplitude to lead to the collapse of the colonnade in a shear-slip mode between the drums. However, low-frequency harmonic excitations are more prominent to cause structural collapse of the two-storey colonnade than the high-frequency ones with predominant rocking failure mode. Finally, the 2D analysis found to be unconservative since underestimates the displacement demands of the colonnade system when compared with the 3D analysis.
