  • In the past few decades, effects of natural hazards, such as earthquakes and wind, on existing structures have attracted the attention of researchers and designers. More recently, however, the phenomenon of progressive collapse is becoming more recognized in the field of structural engineering. In practice, the phenomenon can result from a number of abnormal loading events, such as bomb explosions, car bombs, accidental fires, accidental blast loadings, natural hazards, faulty design and construction practices, and premeditated terrorist acts. Progressive collapse can result not only in disproportionate structural failure, but also disproportionate loss of life and injuries. This paper provides an up-to-date comprehensive review of this phenomenon and its momentousness in structural engineering communities. The literature reveals that although the phenomenon of progressive collapse of buildings is receiving considerable attention in the professional engineering community, more research work is still needed in this field to develop a new methodology for efficient and inexpensive design to better protect buildings against progressive collapse.

  • The development of life science has given many insights into life phenomenons to mankind. Nevertheless, many questions for various phenomenon in life has not been satisfied. Recently, scientific development in human's knowledge showed the limitation of science comparing With the variety of life phenomenon. The fundmental reason of the limitation is thought that the subject of study in life science has been material, and so life has been thought a matter of material in life science. The thought of Hu Jun about this problem, the nature of living things is an important interest in Korean Traditional Medicine, Haneuihak(韓醫學). In this study, the view of human body and disease of Hu Jun(許浚) about the nature of living things which was appeared in 『Donguibogam』 was illuminated. The content of 『Donguibogam』 was edited in the order of Naekyung(內景篇; internal part of the body)ㆍOuihyung(外形編; external part of the body)ㆍJabbyung(雜病篇; diseases)ㆍTangaek(湯液偏; medicinal decoction)ㆍChimgu(針灸篇; acupuncture and moxibustion). The part of Naekyung(內景篇; internal part of the body) is thesis about basic theories and his thought about human body and life, which was seen in ‘Shinhyungjangbu-do(身形臟腑圖; figure of body and shape, and the organs and viscera)’ㆍthe part of ‘Jeong(精)’ㆍ‘Gi(氣)’ㆍ‘Sin(神)’ theory. In this study, the parts which were related with his view of life were selected and compared with the China philosohy of those days to elucidate what is his thought of life appeared in 『Donguibogam』.

  • As the demand of internet networks using backbone communication systems recently increased, the researches on the high-speed wideband optical communication systems are required. For high-speed optical communication systems, asymmetric sampled grating distributed feedback laser diodes (DFB-LDs) are developed and the reliability of DFB-LDs is examined. The reliability of DFB-LDs is performed by monitoring I-V and L-I characteristics and two degradation phenomena related to the electrical characteristics of LDs are observed during the life tests. The first degradation phenomenon by increasing the reverse current is considered as a formation of leakage current path enough to prevent lasing operation in lateral blocking layer near active region of lasers. The second degradation phenomenon by decreasing the forward current is considered as activation of non-radiative Auger recombination process by thermal energy and the second degradation phenomenon is recovered after the off-test period at room temperature Eventually, evaluating the reliability of DFB LDs can allow us to improved the manufacturability in high-volume manufacturing.

  • Mukbang, which appeared through the new media platform in the early 2000s, reflected the life of the young generation who had to eat alone in the face of deteriorating socio-economic conditions. Many young people were able to watch Mukbang together, and gain comfort by establishing a virtual community of everyday life with those who suffered similar difficulties. Since then, Mukbang has evolved into various forms, reflecting the society and also accommodating the needs of viewers, and now it has become a global phenomenon, not just in Korea. Early research focuses on the phenomenon as a bizarre side that appears in the early stages rather than the growth and change of Mukbang, and deals with it in a limited way. This article critically examines these limitations, and examines how the growth and development of Mukbang interacted with the social change process, and how the uniqueness of Mukbang could emerge in the characteristics of the new media. Through this, we will be able to look at the context of the growth of Mukbang as a global phenomenon and the impact on the legacy media.

  • From 20th century, the perception of the problem on self-loss originated from philosophy and emerged in the pursuit of study on humans in real life, not from metaphysical questions. In particular, Phenomenon theory originating from Husserl has been unfolding around, above all, body concepts about human experiences. This is the part where Phenomenon theory finds its meaning as an analytical method of real space concepts. In addition, subjects' perception of situation is done through sense organs not only with sight but also with space-sensible aspects. And since these perceptions are done in consecutive and procedural times, they are done in the experience which shows transitional attributes. The experience elements of transitional senses in situation should be considered more about perception experience of human beings than other spaces, and classify into physical and program elements the introductory parts of eating and drinking spaces where the movements of active perceptionists and the flow of spaces can be felt. And this grants experimental, not usual, characteristics

  • Contemporary Chinese "micro-perspective" painting is an artistic phenomenon that we cannot ignore. It is the young artists who focus on themselves and their communities, record their stories and emotions in their life fragments into the coming history, and diary paintings as "micro-perspective" paintings allow "marginal people" to find their place. Based on the analysis of the aesthetic form and aesthetic characteristics of Chinese contemporary art, this paper explores the three aesthetic dimensions and their inherent aesthetic value, and explains its significance from the perspective of "micro-view" aesthetics. In the contemporary context, "micro-perspective" painting has become a unique cultural phenomenon, a consciousness situation. However, this phenomenon has a very unique artistic value and cultural value for the youth art group and even the formation of aesthetic culture and zeitgeist in China's current society.

  • Purpose: The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience. Methods: Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory. Results: The core of the category found in this study was "overcoming the unstable sense of self- control and integrating disease experience into their life". The causal conditions triggering the central phenomenon were "restriction in daily life" and "manifestation and aggravation of symptom". The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was "unstable sense of self control". The intervening condition for unstable self control were "micro system support" and "motivational resources". This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management. Conclusion: This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

  • Reading and writing in the past make noble significance in 'narration', in other words, in 'the creation of narration', through the process of 'recording'; but in the modern times, it engenders controversies over narration and linearity. In other words, reading/writing in digital era, is devalued as the simple arrangement of test or the connection of vast information without narration nor linearity. However, the reading/writing through text and hypertext reading is not the phenomenon which should be criticized because of the lack of narration or linearity-not only the lack of narration and linearity -, a process of social and cultural transition; it should be revalued as a result. The change of reading and writing methods will inevitably accompany the layers, status, significance and value of the contents; thus it makes more sense, when the reading and writing methods in digital contents are approached as new pop culture phenomenon. This is the "The prose of everyday life", based on pop culture and "The society of Conversation", based on communication; proposed 'Digitelling' ; this is the reason why we should pay attention to the digital contents, created infinitely by the citizens of the world, as new mass-culture phenomenon.
