The effect of high electric current density on the sintering of Ag wires manufactured by screen printing is evaluated throughelectrical resistivity analysis and microstructure observation. Different forms (continuous and pulsed) of electric currentwith different current densities are applied to the specimens. Conventional heat treatment is also performed as a controlgroup to examine the athermal effect of electropulsing treatment. Compared to the conventional heat treatment, the resistivityis reduced more under the electropulsing treatment with continuous current for the same temperature and treatment time.Also, the process time of electropulsing treatment can be reduced by applying a pulse form of high density current insteadof continuous current without losing the benefit of enhanced reduction of resistivity. The microstructural observationsobtained from high angle annular dark field scanning transmission electron microscope and a digital precession instrumentclearly show that necking connecting the crystals is formed more firmly under electric current. In addition, the temperaturechange of Ag wire and substrate is calculated according to the change of the resistivity when the electric current is appliedto confirm the reliability.

김홍범 ( Hong Beom Kim ),이영주 ( Young Ju Lee ) 한말연구학회 2012 한말연구 Vol.- No.31

Based on the semantic description model of Hong-Beom Kim [2008], we utilized the Microsoft Excel and analyzed 339 symbolic words in the「Classification Dictionary of Korean Onomatopoeic and Mimetic Words」. They found the limit of the consistency and systematic method of the semantic description contents by analyzing「Classification Dictionary of Korean Onomatopoeic and Mimetic Words」. It is difficult to systematize human`s psychology, emotion and the like. We classified the sectors as sense, emotion and perception to solve this problem. The results of the analysis for symbolic words based on the methology of this paper remain to be studied.

To investigate the role of adjuvant for cytotoxic T lymphocytes (CTL) induction, squalene-based adjuvant was studied its capability eliciting to the induction of cellular immunity as well as humoral immunity to exogeneous proteins. Ovalbumin (OVA) was used as model proteins. It was demonstrated that antigen formulation consisted of metabolizable oil squalene mixed with Tween 80 and pluronic L121 (S/TJ121) could induced the antigen specific CTL responses and antibodies irrespective of immunization routes in mice. We also demonstrated that this antigen formulation was a inducer of CD8+, major histocompatibility complex(MHC) class I-restricted, and antigen-specific C;1'Ls. These data suggest that the squalene-based emulsion system is a potent adjuvant inducing cellular immunity as well as humoral immunity.

Cytokine and Tumor Environments

Jin Tae Hong1*, Ju Kyung Song, Sun Mi Kwon, Byung Woo Ahn, Youngsoo Kim, Sang Bae Han 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.1

Cytokines are known to function as regulatory molecules that can be produced by virtually every nucleated cell type in the body, including lymphocytes, monocytes/macrophages, epithelial cells, fibroblasts, and many others. Cytokines include lymphocyte-derived factors (lymphokines), monocyte-derived factors (monokines), hematopoietic factors (colony-stimulating factors), connective tissue/growth factors, and chemotactic chemokines. Cytokines released in response to infection can affect tumor development in different ways. When exposed to infectious agents, cytokines are secreted by sentinel cells, such as macrophages and dendritic cells. These cytokines include interleukin 1 (IL-1) and tumor necrosis factor-α, as well as others, such as IL-6, IL-12, and IL-18. When released in sufficient quantities, these molecules can cause inflammation. Chronic inflammation is highly associated with tumor initiation, promotion, and progression. In this article, we review the roles and mechanisms of cytokines in tumor development.

The object of this research is about how jeon-ju, which is one of the historical cities is changed according to the flow of generation. In this analysis, product and enemy factors will be studied. The inner and urban landscape of the generations of the 1860s, 1930s and modern times will be surveyed and compared in the context to grasp those factors. Analysis will be applied to this modern historical city by theorizing how these factors will effect future development. Today's modern landscape will be compared and analyzed based on the effects and abstractions of the recent landscape immediately preceeding current times. Modern conditions will again be placed in context, by suggesting future potential developments. In the result, first, considering present conditions of the landscape which set the stage for the Japanese invasion, an evaluation will be made on the best course of action for future development of street landscape. Second, the question of preserving the history and culture of this rich and ancient city through network of modern street landscape naturally will be posed. Finally, an analysis of the difference between the old and modern landscape will be evaluated, in preparation for suggestions of future development.

The Identification of Aucklandiae Radix, Inulae Radix, Vladimiriae Radix and Aristolochiae Radix, Using Macroscopic, Microscopic and Physicochemical Methods

Yoon, Jee-Hyun,Park, Ha-Yeong,Kim, Tae-Ju,Lee, Seung-Ho,Kim, Jung-Hoon,Lee, Guem-San,Kim, Hong-Jun,Ju, Young-Sung The Society of Korean Medicine 2014 대한한의학회지 Vol.35 No.4

Objectives: This study aimed for establishing the discriminative criteria for Aucklandiae Radix, Inulae Radix, Vladimiriae Radix and Aristolochiae Radix, which can be confused as 'Mokhyang', because of similar appearances and synonyms. Methods: Morphological characteristics of dried herbal medicines were compared by macroscopic observation. To examine microscopic features of 'Mokhyang', paraffin embedding and the staining by using Ju's method were conducted. Physicochemical experiments were performed using HPLC analysis and antioxidant assay. Results: The types of stem, phyllotaxy and leaf shape were chosen as macroscopic criteria and the size, oil spots, color and root top as well as phloem and central cylinder were compared using microscopic features. The HPLC results showed different amounts of costunolide and dehydrocostuslactone among Aucklandiae Radix, Inulae Radix and Vladimiriae Radix. However, Aristolochiae Radix only contained aristolochic acid. The antioxidant assays also showed that Vladimiriae Radix exhibited strongest antioxidant activity followed by Aucklandiae Radix, Inulae Radix and Aristolochiae Radix. Conclusions: These results demonstrate that macroscopic, microscopic and physicochemical methods would be useful tools for the discrimination of 4 kinds of 'Mokhyang'.

Stress induced cardiomyopathy is characterized by transient left ventricular dysfunction with typical regional wall motion abnormality of basal segment hyperkinesia and apical hypokinesia after physical or psychological stress. Stress induced cardiomyopathy mimics acute myocardial infarction but coronary angiography shows normal and usually recovers rapidly. Stress induced cardiomyopathy appears to occur almost exclusively in old females. Only a few cases have been reported in younger women but not yet in korea. The pathogenesis is not well known. Currently, it is thought that catecholamine may play important role. Especially, epinephrine may be most important catecholamine in the pathogenesis of steress induced cardiomyopathy. We report a case of stress induced cardiomyopathy occurred in young female after local epinephrine injection for hemostasis during tonsillectomy. 스트레스성 심근병증은 고령의 여성에서 주로 발생하며 카테콜라민 중 특히 epinephrine이 병리기전의 주요한 원인의 하나로 생각되어지고 있다. 저자들은 28세의 젊은 여성에서 편도절제술 도중 지혈을 목적으로 epinephrine을 국소 주사한 후 발생한 스트레스성 심근병증 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.
