Several animal species including pigs are directly involved in the zoonotic transmission of the hepatitis E virus (HEV) to humans. This study was conducted to detect HEV in bovine and porcine raw livers by nested reverse transcription-polymerase chain reaction. Zoonotic HEV strains were identified in 1.0 and 3.0% of the tested bovine and porcine livers, respectively. HEV-4 was detected in the bovine livers, but both HEV-3 and HEV-4 were identified in the porcine livers. These results indicate that zoonotic transmission of HEV may occur via consumption of raw or undercooked livers of pigs and cattle.

Background: The ginsenoside Rg1 has been shown to exert various pharmacological activities with health benefits. Previously, we have reported that Rg1 promoted myogenic differentiation and myotube growth in C2C12 myoblasts. In this study, the in vivo effect of Rg1 on fiber-type composition and oxidative metabolism in skeletal muscle was examined. Methods: To examine the effect of Rg1 on skeletal muscle, 3-month-old mice were treated with Rg1 for 5 weeks. To assess muscle strength, grip strength tests were performed, and the lower hind limb muscles were harvested, followed by various detailed analysis, such as histological staining, immunoblotting, immunostaining, and real-time quantitative reverse transcription polymerase chain reaction. In addition, to verify the in vivo data, primary myoblasts isolated from mice were treated with Rg1, and the Rg1 effect on myotube growth was examined by immunoblotting and immunostaining analysis. Results: Rg1 treatment increased the expression of myosin heavy chain isoforms characteristic for both oxidative and glycolytic muscle fibers; increased myofiber sizes were accompanied by enhanced muscle strength. Rg1 treatment also enhanced oxidative muscle metabolism with elevated oxidative phosphorylation proteins. Furthermore, Rg1-treated muscles exhibited increased levels of anabolic S6 kinase signaling. Conclusion: Rg1 improves muscle functionality via enhancing muscle gene expression and oxidative muscle metabolism in mice.

Over the past 20 years, academic interest in body and embodiment has become a key topic, with a sharp increase in social science, cognitive science, and neuroscience. The contemporary era is undergoing major changes in our daily lives through digital technology and globalised networks. Digital technology promotes widespread shifts and interaction between people, language, and artifacts on a previously unimaginable scale, and is rapidly changing our environment. The ability to read, write, and communicate for this should not just be the ability to operate media, but should be able to interact with each other, reflecting the process of creating a person’s existence, thinking, and meaning in a critical and human way. Contemporary communication crosses the media and huge information in the digital world is made quickly and in a variety of ways. Now that the world is constantly moving rapidly in the digital world, education cannot rule out the communication flow of reading and writing for this movement. Text for education is no longer written letters. The body can not only allow external experiences through these digital media tools, but also influence our internal experiences with the help of digital media. Now that the digital world is spreading at a rapid pace, it is essential to consider whether it is a contemporary bodily knowledge, and to consider what changes dance education should interact with digital space in a time of rapid change in communication. Therefore, this study aims to recognise the need for change in dance education, depict the body’s cognitive embodiment in the digital world, and consider digital identity expression through this, and examine untact dance education cases as follows. First, for the discussion of digital embodiment, the digital existence and body through transliteracy are considered. Second, in order to consider the expression of digital identity, experience through untact dance education cases is discussed along with transliteracy dance text.

성인의 전환적 학습과 무용

When learning adults, we no longer see it as simply acquiring knowledge and skills. Adult learners often seek more education to learn new knowledge or not fall behind in order to adapt to social changes. At the same time, we should learn to make our own interpretations rather than act on other people’s purposes, beliefs, judgments, and emotions. Promoting such understanding is the basic goal of adult education. The core of transformative learning is defined as the process of transforming the frame of reference already held by adults, including mental habits, perspectives, assumptions, and expectations, and focuses on understanding the meaning of experience with autonomous thinking. This study explores the question of how basic values and assumptions already established throughout adult life, such as society, culture, and education, can be transformed through learning by exploring the transformative learning as a way to transform the meaning of these experiences into new thinking. Therefore, this study discusses the value and role of dance as the transformative learning for adults by discussing where dance is located and how it plays its role in transform the frame of reference for communication, and aims to expand dance education. This study discusses the following purpose: First, to investigate education for value and communication to a new perspective in adults, it discusses the concept of the transformative learning and the critical reflection, which is the essence of adult education, and explore the dance to communication. Second, to explore the transformative learning as open communication that sympathises with others, it explores emotion and body implications in the transformative learning recognition and depicts the role of dance for the reconstruction and expansion of adult baseline frames.

The advent of massmedia introduces the change of perspectives with offering expanded the spectrum of the learning methods through various languages of technology, platform, communication format, and different contents. This allows great challenges to the various disciplines especially the education sphere. There is learning, which is under the environment of rapid changes, through the enhanced interaction, participation, ubiquitous information and communication penetration. Consequently, it causes the occurrence of the new forms of expression through media literacy and digital literacy. This means it is inevitable that we have to be aware of reading and writing through media technology. Transmedia is able to develop the contents of communication through learning of the media technology method of the application. It becomes popular as a learning method internationally because it adapts the space between learners, learners and teachers into a new sphere with amplifying the synergy. Therefore, this study aims at offering the principles and the foundation of dance learning design. This study considers that, Firstly, it explores the elements of the consideration during the process of constructing story to contemplate transmedia space as learning, and the potential capacities of learning, which contains the characteristics of each media, to offer the validity of transmedia learning. Secondly, it examines the notion and the role of text to operate transmedia learning and explores various strategies for the text. Finally, it discusses what is transmitted and what design is approachable to multimedia design and a learning process in dance. It illustrates a transmedia learning design for dance through exploring the narrative elements of dance to solve the problem in online as well as the physical environment.

발제주의 관점을 통한 무용 어포던스 공간 고찰

During the development of our childhood cognition, we naturally learn to recognise how certain objects provide other similar afford in environmental affords for ourselves, permeating the customs shared by our society through experience and becoming a part of the world. Human experience leads to embodied cognition and understands human behaviour. This may in part interchangeably discuss the theory of enactivism approach and affordance theory, with an understanding of areas such as architecture, arts, etc. Dance relies on synesthesia in many ways. The space of dance given to a dancer is made up of the dynamic movements of the dancer’s body, whose dance is constantly moving. However, the dynamics of the body are often underestimated despite the underlying position that the affordance evolves mutually between the agent and the environment in discussing the ever-adjusted affordance, including direct contextual and action-oriented perceptions. Thus, in this study, it extends the intersubjectivity of environments and organisms from organisms to the interaction of agents and others, feeling the need to consider dance with dynamic characteristics of the dancer’s body. Therefore, it aims to extend the affordance space and the concept of dancer’s cognition for dance research field as well as the affordacne research field. First, in order to discuss the affordance of dance, it analyses the correlation between enactivism and the affordance theory to provide validity to the discussion, and analyse the process of dance as a body cognition of the agent’s movements through the special ‘moment’ of dance. Second, it explores how the expansion of the affordance space of dance is achieved through the concept of social affordance, and consider the expansion of intersubjective affordance space of dance.
