  • This study discusses cognition as a computable mapping in cognitive system and relates G del's Incompleteness Theorems to the computability of cognition from a metamathematical perspective. Understanding cognition as a from of computation requires not only Turing machine models but also neural network models. In previous studies of computation by cognitive systems, it is remarkable to note how little serious attention has been given to the issue of computation by neural networks with respect to G del's Incompleteness Theorems. To address this problem, first, we introduce a definition of cognition and cognitive science. Second, we deal with G del's view of computability, incompleteness and speed-up theorems, and then we interpret G del's disjunction on the mind and the machine. Third, we discuss cognition as a Turing computable function and its relation to G del's incompleteness. Finally, we investigate cognition as a neural computable function and its relation to G del's incompleteness. The results show that a second-order representing system can be implemented by a finite recurrent neural network. Hence one cannot prove the consistency of such neural networks in terms of first-order theories. Neural computability, theoretically, is beyond the computational incompleteness of Turing machines. If cognition is a neural computable function, then G del's incompleteness result does not limit the compytational capability of cognition in humans or in artifacts.

  • DNA damage checkpoint is an important self-defense mechanism for the maintenance of genome stability. Defects in DNA damage signaling and repair lead to various disorders and increase tumor incidence in humans. In the past 10 years, we have identified many components involved in the DNA damage-signaling pathway, including the product of breast cancer susceptibility gene 1 (BRCA1). Mutations in BRCA1 are associated with increased risk of breast and ovarian cancers, highlighting the importance of this DNA damage-signaling pathway in tumor suppression. While it becomes clear that BRCA1 plays a crucial role in the DNA damage responsive pathway, exactly how BRCA1 receives DNA damage signals and exerts its checkpoint function has not been fully addressed. A series of recent studies reported the discovery of many novel components involved in DNA damage-signaling pathway. These newly identified checkpoint proteins, including RNF8, RAP80 and CCDC98, work in concern in recruiting BRCA1 to DNA damage sites and thus regulate BRCA1 function in G2/M checkpoint control. This review will summarize these recent findings and provide an updated view of the regulation of BRCA1 in response to DNA damage.

  • A new herbal composition. HemoHIM, was developed using irradiated animal models and was successfully applied as an immune-improving agent. In a view that the protection and recovery of immune, hematopoietic and self-renewal tissues are essential for radioprotective agents, HemoHIM was developed based on a novel combination of three edible herbs (Angelica Radix, Cnidii Rhizoma. Paeonin Radix) that meet all those requirements. HemoHIM significantly protected the immune and hematopoietic system and enhanced their recovery in y-irradiated mice. For the application of HemoHIM as a health functional food and a supplementary agent for the cancer patients, the efficacy of HemoHIM to improve the immune functions was further evaluated in immune-depressed animals and humans. Animal studies demonstrated that HemoHIM significantly improved the immune functions in cyclophosphamide-treated mice, aged mice, and dexamethasone-treated mice. In human studies, HemoHIM enhanced the immune activity and cytokine secretion in sub-healthy volunteers, and alleviated the severe leukocyre depression in cancer patients during radiation and chemotherapy. Based on these results, HemoHIM was approved by Korea FDA as a material of health functional food for immune function improvement and will be commercially available soon. This case of HemoHIM research and development suggested that irradiated animals can be good models for biological degenerations such as immune depression, self-renewal tissue damage, and aging for the development of biological modulators.

  • Tritium is the one of the most important radionuclide for workers in nuclear power plants (NPPs) and the public, from the dosimetric point of view. Humans are likely to have internal radiation exposure by tritium inhalation. Radiation exposure by tritium accounts for approximately 7% and 60~90% of the total radiation exposure of NPP workers and the public during normal operation, respectively. Thus, many researches have been conducted to estimate the internal dose by tritium precisely in the world. In terms of tritium dosimetry, this paper provides the current status of research for tritium metabolism and dosimetry.

  • To achieve fully autonomous driving, the perceptual skills of the surrounding environment must be superior to those of humans. The $60^{\circ}$ angle, $120^{\circ}$ wide angle cameras, which are used primarily in autonomous driving, have their disadvantages depending on the viewing angle. This paper uses a multi-angle object recognition system to overcome each of the disadvantages of wide and narrow-angle cameras. Also, the aspect ratio of data acquired with wide and narrow-angle cameras was analyzed to modify the SSD(Single Shot Detector) algorithm, and the acquired data was learned to achieve higher performance than when using only monocular cameras.

  • Modern medical science tends to categorize addiction as a kind of disease, but a Taoist world-view would not consider addiction to be a disease. Taoists do not have a concept of addiction as an eternal substance. Within the Taoist world-view, human beings are meant to live in harmony with the transformative cycles of nature. Human beings achieve self-realization through balancing themselves with nature. This is what is meant by Self-Realization in Harmony with Nature. There is no disease known as addiction when one's life is in harmony with nature. There are two main principles in the Taoist medical worldview. First, is the theory of correspondences. This theory of correspondences is the foundational to Taoism's value-neutral world-view wherein humans are seen as working together with Heaven and Earth in correlative relationships to create harmonious societies. Second, is the principle of harmony and balance in the Universe. One creature can be in harmony with other creatures and learn to appreciate the interconnectedness of all living beings. Survival of the forest is vital to the survival of natural harmony, balance, morality, and environment. The vitality of the human body depends on the movement of Qi energy. According to the principles of Korean traditional medicine, all human problems stem from the mind. There is no madness, no illness, no tempting fate, and even no death outside of what stems from the mind. Within the human body, there are two principles behind energy systems: harmony and balance. When human beings achieve the state of homeostasis, they obtain Qi flows which are associated with the various organs. In doing so, they can always maintain a healthy state of life in accordance with the cosmic rhythm. Taoist philosophy contains advice that prevents addiction. Empty your mind of all thought. Let your heart be peaceful. Finally, all worries are washed away by the cosmic wave.

  • This study is a review of the role of Christian education in the face of ecological crisis and the task of its recovery from the perspective of Moltmann's creation theory. Mankind has achieved epoch-making industrial development through several industrial revolutions. However, as a result, the ecosystem has suffered severe physical aches and has reached the point of revealing anomalies. In the face of such destruction and suffering of the ecosystem, Christian education needs to approach the ecological sensitivity toward the natural world more holistically and present a practical alternative. Moltmann reminds us that today's growing exploitation of nature by humans stems from a human-centered ecological consciousness that the world belongs to humans. At the same time, it suggests a transition to a God-centered ecological world consciousness. 'A community of creation', 'the fellowship of the Triune God', and 'eschatological new creation through the Sabbath' are key concepts that integrate God-centered ecological world consciousness. Based on Moltmann's creation theory, this article examines the ecological sensibility that Christian education should pursue from the point of view of the sacramental creative community, and reviews the role and practical alternatives of Christian education. Through this, it was derived that the world, including humans, is not owned by humans, but is a sacramental community that is built together toward the end as a part of nature and reveals the glory of God. In addition, it was suggested that Christian education need to be recognized as a suffering subject which mediates humanity and the nature of the mutual fellowship of reconciliation. in the fellowship of God. Sabbath keeping education, which celebrates God's creation and aims for the completion of the eschatological creation, will become a practical area for Christian education to practice for the restoration of the collapsed ecosystem. Moltmann's creation theory is significant in that it provides a meaningful Christian educational insight to restore the ecological environment as well as interest in the ecological environment that has been overlooked or ignored by Christian education.

Analysis of the Views of Nature of Elementary and Secondary School Students and Teachers and Its Implications for Science Education : Focusing on the Korean Traditional Views of Nature (초·중등학교 학생과 교사의 자연관 분석 및 과학교육에 주는 함의 : 한국의 전통적 자연관을 중심으로)

  • In this study, it was analyzed first the views of nature of elementary and middle school students using the analysis framework of the views of nature that reflects the results of the literature analysis on the traditional views of nature that Koreans traditionally have. Next, it was analyzed characteristics of the views of nature which elementary and secondary school teachers. Finally, it was discussed the implications of the results of analysis of students' and teachers' views on science education in elementary and secondary schools. For this purpose, the framework for analysis the views of nature was reconstructed by combining the characteristics of Korean's traditional views of nature (Lee & Son, 2017) with the framework developed by Cobern and his colleagues (Cobern, Gibson, & Underwood, 1995). And in order to analyze in depth how students and teachers perceive nature, each question was asked to write a reason why they thought about their responses. According to the study, students and teachers respected nature and viewed it as a living creature, and had the view that nature was cyclical and that humans and nature interacted with each other. And they also had a traditional Korean view of nature that they consider naturalness important and nature is beautiful. It can be said that this is different from the view of Western modern science which perceives the world as a material and see nature with the view of linear time. Therefore, Korea's traditional views of natures, which students and teachers have, can be a conflict with the view of modern science in science class. Therefore, the science teaching strategy for students and teachers with different natural views will require consideration of the individual's understanding of nature and lesson strategies related to it. And it is also necessary that science textbook and science class cultures need to actively interact with teachers and students, and between students to share and understand each other's view of nature, and create a science class culture that considers the values students have and views on nature.

  • This paper focuses on the social implication of new media art, which has evolved with the advance of technology. To understand the notion of human-computer interactivity in media art, it examines the meaning of "cybernetics" theory invented by Norbert Wiener just after WWII, who provided "control and communication" as central components of his theory of messages. It goes on to investigate the application of cybernetics theory onto art since the 1960s, to which Roy Ascott made a significant contribution by developing telematic art, utilizing the network of telecommunication. This paper underlines the significance of the relationship between human and machine, art and technology in transforming the work of art as a site of communication and experience. The interactivity in new media art transforms the viewer into the user of the work, who is now provided free will to make decisions on his or her action with the work. The artist is no longer a godlike figure who determines the meaning of the work, yet becomes another user of his or her own work, with which to interact. This paper believes that the interaction between man and machine, art and technology can lead to various ways of interaction between humans, thereby restoring a sense of community while liberating humans from conventional limitations on their creativity. This paper considers the development of new media art more than a mere invention of new aesthetic styles employing advanced technology. Rather, new media art provides a critical shift in subverting the modernist autonomy that advocates the medium specificity. New media art envisions a new art, which would embrace impurity into art, allowing the coexistence of autonomy and heteronomy, embracing a technological other, thereby expanding human relations. By enabling the birth of the user in experiencing the work, interactive new media art produces an open arena, in which the user can create the work while communicating with the work and other users. The user now has freedom to visit the work, to take a journey on his or her own, and to make decisions on what to choose and what to do with the work. This paper contends that there is a significant parallel between new media artists' interest in creating new experiences of the art and Jacques Ranci$\grave{e}$re's concept of the aesthetic regime of art. In his argument for eliminating hierarchy in art and for embracing impurity, Ranci$\grave{e}$re provides a vision for art, which is related to life and ultimately reshapes life. Ranci$\grave{e}$re's critique of both formalist modernism and Jean-Francois Lyotard's postmodern view underlines the social implication of new media art practices, which seek to form "the common of a community."
