  • 해상 사고에 의한 익수자는 저체온증에 의한 사망 위험에 노출되어 있다. 구명 동의 등을 착용함으로써 부력은 유지할 수 있으나 해수의 낮은 온도에 의한 신체의 열손실은 짧은 시간 내에 체온을 하강시키고 그에 따른 저체온증 사망이 우려된다. 전통적인 구명 동의는 고체형 부력체를 사용하여 부력을 향상 시키고 있으나, 구명 동의에 공기를 채움으로써 부력 및 체온 보존 효과를 얻을 수 있을 것으로 판단된다. 본 연구는 고체형 충진재를 이용한 기존의 비 팽창형 구명 동의와 공기를 채운 팽창형 구명 동의의 단열 성능을 비교하고, 각각의 방법이 체온 변화에 미치는 영향을 정성적으로 평가하고자 한다. 먼저 열저항 모델을 이용한 대략적인 단열 성능의 비교를 실시하고, 유한요소법을 이용하여 Pennes의 신체 열전달 해석을 수행하여 시간에 따른 체온 변화를 수치적으로 검토하였다.

  • DNA methylation is a regulatory mechanism in epigenetics that is frequently altered during human carcinogenesis. To detect critical methylation events associated with gastric cancer (GC), we compared three DNA methylomes from gastric mucosa (GM), intestinal metaplasia (IM), and gastric tumor (GT) cells that were microscopically dissected from an intestinal-type early gastric cancer (EGC) using methylated DNA binding domain sequencing (MBD-seq) and reduced representation bisulfite sequencing (RRBS) analysis. In this study, we focused on differentially methylated promoters (DMPs) that could be directly associated with gene expression. We detected 2,761 and 677 DMPs between the GT and GM by MBD-seq and RRBS, respectively, and for a total of 3,035 DMPs. Then, 514 (17%) of all DMPs were detected in the IM genome, which is a precancer of GC, supporting that some DMPs might represent an early event in gastric carcinogenesis. A pathway analysis of all DMPs demonstrated that 59 G protein-coupled receptor (GPCR) genes linked to the hypermethylated DMPs were significantly enriched in a neuroactive ligand-receptor interaction pathway. Furthermore, among the 59 GPCRs, six GI hormone receptor genes (NPY1R, PPYR1, PTGDR, PTGER2, PTGER3, and SSTR2) that play an inhibitory role in the secretion of gastrin or gastric acid were selected and validated as potential biomarkers for the diagnosis or prognosis of GC patients in two cohorts. These data suggest that the loss of function of gastrointestinal (GI) hormone receptors by promoter methylation may lead to gastric carcinogenesis because gastrin and gastric acid have been known to play a role in cell differentiation and carcinogenesis in the GI tract.

  • The cinema of Peter Greenaway has consistently engaged questions of the relationship between the arts and particularly the relations of image and writing to cinema. When different types of images are correlated and merged with each other on the borders of painting, photography, film, video and computer animation, the interrelationships of the distinct elements cause a shift in the notion of the whole image. This analysis proposes to articulate the complex relationship between the 'interartial' dimension and the 'intermedial' dimension in Peter Greenaway's film, (1991). If the interartiality is interested in the interaction between various arts, including the transition from one to another, the intermediality articulates the same type of relationship between two or more media. The interactional relationship is the same on both sides; on the contrary, the relationship between art and media does not show the same symmetry. All art is based on one or more media - the media is a condition existence of art - but no art can't be reduced to the status of media. This suggests that if the interartiality always involves the intermediality, this proposal may not be reversed. First, we analyse a self-conscious investigation into digital art and technology. Prosospero's Books can be read as a daring visual essay that self-consciously investigates the technical and philosophical functions of letters, books, images, animated paintings, digital arts, and the other magical illusions, which have been modern or will be post-modern media to represent the world. Greenaway uses both conventional film techniques and the resources of high-definition television to layer image upon image, superimposing a second or third frame within his frame. Greenaway uses the frame-within-frame as the cinematic equivalent of Shakespeare's paly-within-play : it offer him the possibility to analyse the work of art/artist/spectator relationship. Secondly, we analyse the relationship between the written word, oral word and the books. Like the written word, the oral word changes into a visual image: The linguistic richness and nuances of Shakeaspeare's characters turn into the powerful and authoritative, but monotone, voices of Gielgud-Prospero, who speaks the Shakespearean lines aloud, shaping the characters so powerfully through his worlds that they are conjured before us. Specially each book is placed over the frame of the play's action, only partially covering the image, so that it gives virtually every frame at least two space-time orientations. Thirdly, we try to show how Peter Greenaway uses pictorial references in order to illustrate the context of the Renaissance as well as pictorial techniques and language in order to question the nature of artistic representation. For exemple, The storm is visualised through reference to Botticelli's : the storm of papers swirling around the library is constructed to look like a facsimili copy of Michelangelo's Laurentiana Library in Florence. Greenaway's modern mannerism consists in imposing his own aesthetic vision and his questioning of art beyond the play's meta-theatricality: in other words, Shakespeare''s text has been adapted without being betrayed.

  • Developments in the understanding of fire behaviour for large open-plan spaces typical of tall buildings have been greatly outpaced by the rate at which these buildings are being constructed and their characteristics changed. Numerous high-profile fire-induced failures have highlighted the inadequacy of existing tools and standards for fire engineering when applied to highly-optimised modern tall buildings. With the continued increase in height and complexity of tall buildings, the risk to the occupants from fire-induced structural collapse increases, thus understanding the performance of complex structural systems under fire exposure is imperative. Therefore, an accurate representation of the design fire for open-plan compartments is required for the purposes of design. This will allow for knowledge-driven, quantifiable factors of safety to be used in the design of highly optimised modern tall buildings. In this paper, we review the state-of-the-art experimental research on large open-plan compartment fires from the past three decades. We have assimilated results collected from 37 large-scale compartment fire experiments of the open-plan type conducted from 1993 to 2019, covering a range of compartment and fuel characteristics. Spatial and temporal distributions of the heat fluxes imposed on compartment ceilings are estimated from the data. The complexity of the compartment fire dynamics is highlighted by the large differences in the data collected, which currently complicates the development of engineering tools based on physical models. Despite the large variability, this analysis shows that the orders of magnitude of the thermal exposure are defined by the ratio of flame spread and burnout front velocities (VS / VBO), which enables the grouping of open-plan compartment fires into three distinct modes of fire spread. Each mode is found to exhibit a characteristic order of magnitude and temporal distribution of thermal exposure. The results show that the magnitude of the thermal exposure for each mode are not consistent with existing performance-based design models, nevertheless, our analysis offers a new pathway for defining thermal exposure from realistic fire scenarios in large open-plan compartments.

  • 본 연구는 고려시대부터 조선 후기까지 궁궐 왕의 행차, 나례, 사신영접, 연회 등의 목적으로 조설되었던 전통공연예술분야의 무대장치인 산대(山臺)의 유형, 구조적 형상, 표상의 원리를 고찰하여 동시대 석가산(石假山) 조영 문화의 확장성을 제시하고자 하였으며, 그 결론은 다음과 같다. 첫째, 산대의 발달사와 그 의미를 통해 외부공간에 '산'의 형상을 실체화하고자 한 석가산의 조영 문화와의 동질성을 갖고 있다는 사실을 확인할 수 있었다. 산대를 만드는 행위 자체는 명산을 숭배하는 전통과 관련이 깊다. 이는 고려 예종 '청연각' 앞뜰에 조성된 석가산에서 중국의 명산명호(名山名湖)가 표상적으로 비유되어 모사(摹寫)된 사실과도 일치한다. 둘째, 산대와 석가산은 그 구조적 형상과 재료, 기술적 제작방식은 달랐으나 산의 형상을 조형하여 완상하거나 국가행사의 무대배경으로 활용되며, 다양한 유형으로 나타나고 있었다. 산을 모사한 산대의 형상과 상징적 의미는 요산요수(樂山樂水)로 대표되는 당대의 정원 및 예술적 관심사가 산수의 다양한 조형적 표현으로 귀결되고 있음을 알 수 있다. 셋째, 신재효의 고택의 정원 중앙에 위치했던 것으로 추정되는 연(蓮)이 심겨진 방지와 이에 인접한 수각과 석가산은 정원을 수식하는 요소일 뿐 아니라 신재효의 문하생의 수련 및 공연무대의 배경으로 기능을 수행했을 것으로 추정된다.

  • 본 연구는 중의성을 가진 어휘가 심성 어휘집에 표상된 방식과 감각 양상에 따른 처리 과정을 알아보기 위하여 한국어 동음동철이의 어절의 시·청각 재인 과정을 조사하였다. 청각 어절 판단 과제(실험 1)와 시각 어절 판단 과제(실험 2)를 이용한 두 실험에서 두 가지 이상의 의미를 가진 동음동철이의 어절(예: '물었다')과 단일한 의미만을 가진 통제 어절(예: '고통을')이 사용되었다. 어절 자극들의 누적 빈도는 조작하는 한편, 각 동음동철이의 어절의 다양한 의미가 가지는 상대적 빈도는 통제하였다. 어절 판단 과제를 사용한 두 실험 모두에서 유의한 빈도의 주효과와 함께 의미 수에 따른 어절 유형과 빈도 간의 상호작용이 발견되었다. 실험 1에서 청각적으로 제시된 동음동철이의 어절은 저빈도 조건에서 단의 어절에 비해 반응시간이 빠른 중의성 이득 효과가 나타난 반면, 고빈도 조건에서는 이와 반대로 비이득 효과가 나타났다. 마찬가지로 시각적으로 제시된 실험 2의 자극에서도 유사한 상호작용 패턴이 발견되었다. 본 연구 결과는 시각 및 청각 양상 모두에서 어휘-의미 처리가 상호의존적으로 이루어짐을 보여주며, 이는 의미 처리가 감각 의존적 단계보다는 일반적 어휘 지식 처리 단계에서 이루어질 가능성을 시사한다. 이와 더불어 의미 선택 과정에서 동음동철이의 어절이 가지는 다양한 의미의 후보군은 어절의 빈도가 상대적으로 낮을 때에만 촉진적 피드백을 제공함을 보여준다.

  • Given the prevalence of violence in Ukrainian families, measures to prevent parental abusive treatment against children are urgent. It is important to study today's youth awareness about violence within families in order to enhance a culture of engagement with spouses and children in future. The aim of the study is to examine students' reflective experiences and their attitudes towards forms, frequency, causes and effects of parental abusive treatment. During the research the following methods were used step-by-step: theoretical analyses of scientific resources, anonymous questionnaire, quantitative and correlation analyses. According to result of survey 98 students who were interviewed, none of them fell victim of sexual abuse in their families. However, more than a half (51%) of the students surveyed experienced some forms of parental physical punishment. All the interviewed students encountered psychological cases of parental violence. The mostprevalent forms of parental abuse among the interviewees are criticism, negative comparison, emotional detachment, arrogance, intimidation, blackmail and humiliation. The most prevalent consequences of parental abuse among students are anxiety, low self-esteem, insecurity, impatience, suspiciousness, constraint in communication. Students agree that budget limitations, forced labor, criticism, spanking, emotional detachment, ignoring type of communication, reproach, blackmail are acceptable methods of punishment to use when raising their own children. These results clearly demonstrate the problem of the impact of parental abuse on children and its consequences in the future. A virtual dimension of the actualized problem is considered, namely: - virtualization of aggression and cruelty in the postmodern world. - the level of determining the factor of cruelty from the space of virtual culture. - the mirror image of everyday cruelty in the virtual environment; - the phenomenon of video games as a source and context of representation of the factor of cruelty in behavioral realities; - cybercrime as a virtualized result of cruelty in family and everyday realities. - futurological perspectives of virtualization of cruelty in communicative culture in general and in family relations in particular. The postmodern world is fundamentally different from the traditions and culture of the past, primarily due to the development of computer technologies and the virtualization of life in general. So, for example, virtual communities have become, in a certain way, another world, a second reality of life in general. And certain behavioral factors, in particular cruelty in the private environment, became a projection of such a phenomenon as cybercrime. Video games are a unique modern phenomenon, which multipolarly absorb all facets of human potential, communicative tendencies, behavioral and characterological factors, from the warmth of interpersonal relationships to the extreme degree of cruelty.

  • European integration processes have acted as a catalyst for the emergence of a new type of educational environment, which is characterized by competent flexibility of specialists. Therefore, the article focuses on professional training of teachers in the context of European integration processes using information technology and the search for innovative methods of training specialists. One of the educational priorities in Europe is to create a new model of a teacher who has an academic education, knows innovative methods, is able to perform functions and tasks efficiently and professionally, adequately, quickly and correctly respond to changes and innovations. The tasks facing education in the European dimension are formulated. The main trends in the education of teachers in modern Europe are described: the need to deepen and expand subject training programs in pedagogical institutions of Higher Education, which will allow autonomy of activity, awareness of responsibility for independent creative decisions, create favorable conditions for the development of professionalism through the use of Information Technology and the search for innovative methods of training specialists. At the present stage, various models of teacher training are being developed based on the University and practical concept using information technology and searching for innovative methods of training specialists. On this basis, two different theories of perception of teacher education were formed: as preparation of teachers for work throughout their professional career; as preparation for the first years of professional work, which is periodically repeated in the process of continuous professional training and improvement. Among the advantages that the use of Information Technology and the search for innovative methods of training specialists to implement the learning process, it is worth mentioning the following: simultaneous use of several channels of perception of the student or student in the learning process, thanks to which the integration of information processed by different sensory organs is achieved; the ability to simulate complex real experiments; visualization of abstract information by dynamic representation of processes, etc.
