  • The isolation of respiratory viruses, especially from clinical specimens, often shows poor efficiency with classical cell culture methods. The lack of suitable methods to generate virus particles inhibits the development of diagnostic assays, treatments, and vaccines. We compared three inoculation methods, classical cell culture, the addition of a JAK2 inhibitor AZD1480, and centrifugation-enhanced inoculation (CEI), to replicate human respiratory syncytial virus (HRSV) and human metapneumovirus (HMPV). In addition, a combined method using AZD1480 treatment and CEI was used on throat swabs to verify that this method could increase virus isolation efficiency from human clinical specimens. Both CEI and AZD1480 treatment increased HRSV and HMPV genome replication. Also, the combined method using CEI and AZD1480 treatment enhanced virus proliferation synergistically. The combined method is particularly suited for the isolation of interferon-sensitive or slowly growing viruses from human clinical specimens.

  • The purpose of this study is to find out how to use emotional activity rate in sentence. The aim is to estimate the Emotion-Codon status of emotion-DNA wiggling as well as the sequence of codons in which amino acids of human body are spread. It is as if the amino acids are translated from the DNA of the human body, and the emotions that cooperate with each other are diversified and refined. Through these attempts, we anticipate the change of emotions by literary works and present the direction of the synapse working and the direction of the encoding. Therefore, this study analyzed the emotional activity of Rated Emotion-Codon, which works as Rated Sijo. At this time, the emotional change in the human body, in which the sentence is more clearly pronounced, is predicted and detected. This result shows how emotions can activate the human body. This state of activation is an indicator of how much the sentence pushes the physiological action of the human body. It is judged that Codon is constructed precisely for the activation of the rated Sijo additive definition by this index. Our result is evidenced by the fact that three sentences of Rated Sijo show an array with the same rating as the Rated Codon's, The first sentence fuses with the sentiment between the second sentence and the third sentence of Rated Sijo. The emotional symbols between the sentence symbols "A, U, J, L" in the first base of the Codon table and the sentences fusing between the sentences of the first sentence and the third sentence are "A, U, J, L". The emotional symbols between the sentences flowing in the second base of the Codon table and between the sentences of the first sentence and the second sentence are structured in the third base of the Codon table as "A, U, J, L". The Rated Sijo, which is resiliently and precisely assigned to the human body's Rated Emotion-Codon, will require a rich experience in our Rated Life.

  • Natural Medicine is a medical system that tries to find the cause and cure of the disease in the nature emphasizing on natural healing power of human body. The most important value of traditional medicine in east Asia lies on the fact that this medicine is a medical culture and natural medicine that was selected by instinct and human nature reflecting the best possible remedy by the wisdom of evolution, and views the living phenomenon based on relation and circulation. This medicine is a natural medicine that tries to recover and promote the natural healing power by vitality and is a system that cumulates various empirical information about unique and complicated life phenomenon as a legacy of evolution in the body and the disease. The understanding of variation and adaptation of human species should be based on thorough knowledge of origin, instinct and nature of human as well as knowledge of survival and adaptation of human and environment based on evolution. And through this insight, the prevention and treatment of modern diseases should be developed. In this regards, traditional medicine in east Asia should be highlighted again as a study on adaptation and harmony of penetrating the cultural history of mind which has led the history of biological body and change of society and culture, and the repository of practical wisdom and knowledge.

  • Human pluripotent stem cells (hPSCs) include human embryonic stem cells (hESCs) derived from blastocysts and human induced pluripotent stem cells (hiPSCs) generated from somatic cell reprogramming. Due to their self-renewal ability and pluripotent differentiation potential, hPSCs serve as an excellent experimental platform for human development, disease modeling, drug screening, and cell therapy. Traditionally, hPSCs were considered to form a homogenous population. However, recent advances in single cell technologies revealed a high degree of variability between individual cells within a hPSC population. Different types of heterogeneity can arise by genetic and epigenetic abnormalities associated with long-term in vitro culture and somatic cell reprogramming. These variations initially appear in a rare population of cells. However, some cancer-related variations can confer growth advantages to the affected cells and alter cellular phenotypes, which raises significant concerns in hPSC applications. In contrast, other types of heterogeneity are related to intrinsic features of hPSCs such as asynchronous cell cycle and spatial asymmetry in cell adhesion. A growing body of evidence suggests that hPSCs exploit the intrinsic heterogeneity to produce multiple lineages during differentiation. This idea offers a new concept of pluripotency with single cell heterogeneity as an integral element. Collectively, single cell heterogeneity is Janus-faced in hPSC function and application. Harmful heterogeneity has to be minimized by improving culture conditions and screening methods. However, other heterogeneity that is integral for pluripotency can be utilized to control hPSC proliferation and differentiation.

  • This paper considers the historical background of the emergence of 'thinking-machine,' that has changed the ontological statue of human and machine. In particular, British mathematician Charles Babbage's Calculating Engines is examined as a material iteration of thinking-machine, focusing on the discursive process by which thought is not the faculty of human, but the function of machine. In Chapter II, I review the dualism of René Descartes who denied the possibility of machine intelligence by separating the substance of body and mind. In Chapter III, Babbage's philosophical assertions which emphasized the function of human associated with thought by rejecting the fundamental opposition between human and machine. Therefore, this paper verifies that the conception of 'thinking-machine' essentially causes the reorganization and reformulation of concepts involved with human identity, and provides the sophisticated sources to prepare new perspective on the artificial technology nowadays.

  • The purpose of this study is to analyze the structural relationship and direct and indirect effects among high school students' self-esteem, democratic parenting attitude, school adaptation, and human rights awareness. The subject of this study is panel data of a total of 3,456 high school students who responded to a study on the implementation of the Convention on the Rights of Children and Youth of the Korea Youth Policy Institute. Data analysis was statistically processed using SPSS 21 and AMOS 21.0 programs. The results of this study showed that high school students' self-esteem had a direct effect on democratic parenting attitudes, school adaptation, and human rights awareness. It was confirmed that the self-esteem of high school students had an indirect effect on human rights awareness through democratic parenting attitudes and school adaptation as a medium. In conclusion, in order to improve high school students' human rights awareness, school of social work is needed considering the causal relationship of all variables.

  • We have cloned a soluble type human folate receptor(hFR type${\gamma}$) from human thymus cDNA library using the PCR amplification technique. To examine whether hFR type${\gamma}$ has a folate transport activity, CHO cells were transfected with the pcDNAhFR${\gamma}$ expression plasmid, and the stable cell line CHO/hFR${\gamma}$ expressing a high level of the hFR type${\gamma}$ was identified by northern and western blot analysis. The CHO/hFR${\gamma}$ cells produced a [$H^3$]folic acid binding protein in the culture medium. However, we couldn't detect any cell surface [$H^3$] folic acid binding and transport activities. The growth of the CHO/hFR${\gamma}$ cells was more rapidly inhibited than the wild type CHO cells in the low concentration folic acid media. These observations indicate that although soluble type human folate receptor can bind [$H^3$]folate, it does not involve in folate transport.

  • So many patterns of the clothing give the specific indication for one's clothing behavior and present the common style for the society. Human being gives the one's free expression and attempts to change the existing cultural environment by the clothing even though human being would be restricted in choosing the clothing within the category of the society & the culture. The value of human being which attempts to escape the restriction through the behavior theory of T. Parsons is analysed and studied. The role of the modern society is being transformed and human being attempts to express one's self through the clothing very strongly. The clothing behavior means the expression of oneself for others. This phenomenon comes from the changing of human being's view of value through the social & cultural environment which give human being the freedom of the individual to choose the various clothing.

  • Mesenchymal stem cells (MSCs) have shown great potential in treating bone deficiency. Human adipose-derived stem cells (HASCs) are multipotent progenitor cells with multi-lineage differentiation potential. Human amnion-derived mesenchymal stem cells (HAMSCs) are capable of promoting osteogenic differentiation of MSCs. In this study, we investigated the effect of HAMSCs on HASCs by a transwell co-culture system. HAMSCs promoted proliferation, osteogenic differentiation, angiogenic potential and adiponectin (APN) secretion of HASCs. Moreover, the positive effect of HAMSCs was significantly inhibited by U0126, a highly selective inhibitor of extracellular signaling-regulated kinase 1/2 (ERK1/2) mitogen-activated protein kinase (MAPK) signaling pathway. These observations suggested that HAMSCs induced bone regeneration in HASCs via ERK1/2 MAPK signaling pathway.
