  • A new simplified procedure for identifying human plasmin was developed using a DTT copolymerized agarose stacking gel (ASG) system. Agarose (1%) was used for the stacking gel because DTT inhibits the polymerization of acrylamide. Human plasmin showed the lowest activity at pH 9.0. There was a similar catalytically active pattern observed under acidic conditions (pH 3.0) to that observed under alkaline conditions (pH 10.0 or 11.0). Using the ASG system, the primary structure of the heavy chain could be established at pH 3.0. This protein was found to consist of three fragments, 45 kDa, 23 kDa, and 13 kDa. These results showed that the heavy chain has a similar structure to the autolysed plasmin (Wu et al., 1987b) but there is a different start amino acid sequence of the N-termini.

  • Cytochrome P45O 2El (CYP2El)의 retropseudogene이 사람에 존재하는지 확인하기 위해 혈액에서 분리한 DNA를 주형으로 한 polymerase chain reaction (PCR)을 수행하였다. Primer는 CYP2E1 유전자를 기초하여 여러개 제작하되 적절한 조합에 따라 정상유전자와 retropseudogene이 동시에 증폭될 수 있도록 고안하였다. 본 실험의 결과 그동안 예상은 되었지만 DNA차원에서 미처확인되지 못하였던 CYP2E1의 retropseudogene을 직접 증폭해낼 수 있었다. 세부 구조는 Southern blotting과 DNA 염기서열 결정에서 최종 분석되었다. PCR 반응으로 증폭된 부분에서는 염기서열이 mRNA와 완전히 일치하고 있는 점으로 미루어서 CYP2E1의 retropseudogene은 비교적 최근에 발생했을 것으로 추정되었다.

  • Today, the convergence of fashion design and digital technology has become a popular method and accordingly been tried variously in the fashion area. This study aimed to analyze the character of the collaboration with fashion and technology, and the meaning of technology as emotional expression methods. Selected designer's collections, literature and other related studies were reviewed in order to analyze the generative structure of the meaning and the binary-opposition in the convergence of body, fashion design and technology. Literatures and selected designer's collections were reviewed and quantitatively studies were performed to classify the convergence of human bodies, fashion design and technology through Greimas Semiotics rectangle based on binary-opposition of meaning and isotophy analysis. The research presents three types of fashion technology methods: mechanical movement, light/digital media, and virtual image. The convergence of fashion and technology was classified as the direct convergence and the indirect convergence. The direct convergence was characterized by variability and has automatic, independent movement, but the indirect convergence was shown closed and to have contradistinctive images.

  • P-glycoprotein (P-gp) is a member of the ATP-Binding Cassette transporter superfamily and mediates transmembrane efflux of many drugs. Since it is involved in multi-drug resistance activity in various cancer cells, the development of P-gp inhibitor is one of the major concerns in anticancer therapy. Human P-gp protein has at least two "functional" drug binding sites that are called "H" site and "R" site, hence it has multi-binding-specificities. Though the amino acid residues that constitute in drug binding pockets have been proposed by previous experimental evidences, the shapes and the binding poses are not revealed clearly yet. In this study, human P-gp structure was built by homology modeling with available crystal structure of mouse P-gp as a template and docking simulations were performed with inhibitors such as verapamil, hoechst33342, and rhodamine123 to construct the interaction between human P-gp and its inhibitors. The docking simulations were performed 500 times for each inhibitor, and then the interaction frequency of the amino acids at the binding poses was analyzed. With the analysis results, we proposed highly contributing residues that constitute binding pockets of the human P-gp for the inhibitors. Using the highly contributing residues, we proposed the locations and the shapes of verapamil binding site and "R" site, and suggested the possible position of "H" site.

  • The Purpose of the study was to understand the experience of chronic renal failure patients for the qualified individual care for them. The purpose of this study was to explore the experience of patients living with chronic renal failure and to identify the meaning and structure of their experience. The subjects were four patients, two females and two males. The age range was from 21 to 54. Data was collected with a few in-depth interviews by the authors until the data was fully saturated. The framework and methodology of this study was based on Parse′s "Human Becoming methodology," an existential phenomenological research methodology. The findings of this study were as follows. Three experience structures of chronic renal failure patients were : 1. Sufferings and conflicts originated in the frustration caused by uncurable disease. 2. Dependence upon God and significant others with complex emotions. 3. Acceptance of sufferings, emerging hope for serving people, and gratitude for living. In conclusion the experience of chronic renal failure patients could be described from the findings (three structures) as "Experiencing the sufferings, conflicts originated in the frustration caused by uncurable disease, dependence upon God and significant others with complex emotion, acceptance of the suffering and hope for serving people, and gratitude for living." The three structures of the lived experience of patients with chronic renal failure, the findings of this study, could be explained by the three concepts of "Theory of Human Becoming," the first structure could be explained with values, the second with revealing-concealing, and the third with transforming.

  • Oriental medicine which is based on internal activeness has constantly been developed for over thousands years and during that time it has encountered Western medicine that has the different system. Because of a lot of different viewpoints of how to understand human and nature, there exist lots of problems to cope with for the integration of two medicines as follows: (1) Oriental medicine regards each person as a cosmos in miniature but Western medicine is based on dualism, substantialism and mechanism. (2) Oriental medicine thinks much of totality as a cosmos in a miniature but Western medicine investigates individual structure and function of human organ and system. (3) Oriental medicine considers that organs are the core of the Oriental medical physiology and makes much account of their functions and their relationships with fundamental texture, but Western medicine gives much emphasis on the structure than functions. Despite of these differences, Oriental medicine and Western medicine should develop mutual understanding and this will facilitate the achievement of the third medicine that is suitable for the primary object of medicine that is to enhance human health and cure diseases.
