본 논문은 한국 근대 디자인, 나아가 한국 근대 미술을 발굴하기 위한 프로젝트의 일환으로, 일본의 제국미술학교(1948년 무사시노 미술학교로 개칭, 1962년 무사시노미술 대학으로 승격) 및 제국미술학교에 유학했던 조선인 유학생들(1929-1945)에 대하여, 무사시노 미술대학과 공동으로 행한 연구조사와 발굴을 바탕으로, 이루어 진 논문이다. 근대 미술과 디자인의 수용과정에서 가장 많은 조선인이 유학하였던 근대 적 미술교육기간이 바로 제국미술학교이 다. 제국미술학교 도안 공예과에 유학했던 조선인 학생들의 활동과 도안 공예과 교수들과의 관계를 고찰함으로서 궁극적으로 일본 제국미술학교 교육을 통한 다자인의 학습과 수용이 조선 유학생들에게 어떠한 영 향을 주었고, 전후의 한국 디자인 교육과 어 떠 한 연관성을 가지는 지 알아보았다. 연구결과 147명의 조선인 유학생 명단과 13명의 공예도안과 유학생명단을 새로 작성하였으며, 본 논문이 자료가 취약한 우리 근대 디자인 사를 복원할 중요한 단서가 될 것이다.

Phthalate plasticizers residue in food is a serious threat to public health. Spores of Ganoderma lucidum are easy to be contaminated with phthalates during collection and processing. In this study, supercritical fluid extraction (SFE) was performed to remove phthalates in spores of G. lucidum, and the effects on acid and peroxide values of spores' oil were also evaluated. The results showed SFE removed 100% of the residual di-iso-butyl phthalate, di-n-butyl phthalate and di-2-ethylhexyl phthalate in the spores of G. lucidum. No significant differences in polysaccharides content and fatty acid composition were observed between SFE and control spores. However, the triterpenoid extracts of SFE spores had a 7.45% increase, significantly higher than that in control spores. Accelerated oxidation tests further implied that SFE could improve the stability of spores' oil. Our results suggested SFE is a potential approach to remove phthalate from food related products.

This thesis is a study on Sook-Jae Lim(1899~1937) and Korean modern design. In modern Korea, design like most cultural advances came from western culture, that was introduced via Japan. So Korean design can be betterunderstood from observing Japanese modern design history. The research on Japanese modern design, however, is not being done actively. Sook-Jae Lim was the first Korean to graduate from the Department of Design at Tokyo Fine Arts School (currently the Tokyo National University of Fine Arts and Music). He died at a premature 38 years old, so very little of his works exist. That makes the study about him very difficult. From this perspective, the study aims to examine modern design concepts and styles accepted into Korea from Japan and position Lim as an early design pioneer in Korean design history, by using research of Korean and Japanese design fields in the modern era with focus on Lim and his works. Chapter II researches the process of how the concept of design was formed in modern Japan and how the "Art-Nouveau" style not only represents early modern design but also features Lim's works dominantly. Chapter III looks into the process of how the concept of design was formed and which design styles were introduced and applied in modern Korea. Chapter IV analyzes how Lim's viewpoint on design and his works were developed with observations about the tendency of the Japanese design field and curriculums of the Tokyo Fine Arts School during the period of his college days.

Purpose - The purpose of this paper is to analyze the net effect of the green total factor productivity (GTFP) of China's manufacturing industry from the China-Korea Free Trade Area (China-Korea FTA) quantitatively. Design/methodology - Firstly, the Global Malmquist-Luenberger (GML) index based on the SBM directional distance function is used to measure the GTFP of China's manufacturing and analyze the driving force for its growth. Secondly, the regression discontinuity quantitative analysis is used to determine the impact of the China-Korea FTA on China's manufacturing GTFP. Findings - Our main findings can be summarized as follows: the China-Korea FTA has promoted the GTFP of China's manufacturing with an effect evaluation mainly resulting from green technology progress. And there is industry heterogeneity in the policy effect on the manufacturing GTFP due to the China-Korea FTA. Namely, policy promotion from the China-Korea FTA is more effective on the GTFP of equipment manufacturing than it is on those of other industries. Originality/value - First, an evaluation and analysis of the GTFP development of China's manufacturing that employs GML index based on SBM directional distance function. Second, a quantitative estimate of China-Korea FTA's net effect on China's manufacturing industrial GTFP that uses regression discontinuity analysis, which is considered to be the closest method to natural experiments and superior to other causal inference methods. Third, an in-depth discussion of the practical steps that China's manufacturing can take to improve GTFP development and integrate China-Korea FTA construction into economic development.

Ginsenoside Rb₁ (Rb₁), one of the most important ingredients in Panax ginseng Meyer, has been confirmed to have favorable activities, including reducing antioxidative stress, inhibiting inflammation, regulating cell autophagy and apoptosis, affecting sugar and lipid metabolism, and regulating various cytokines. This study reviewed the recent progress on the pharmacological effects and mechanisms of Rb₁ against cardiovascular and nervous system diseases, diabetes, and their complications, especially those related to neurodegenerative diseases, myocardial ischemia, hypoxia injury, and traumatic brain injury. This review retrieved articles from PubMed and Web of Science that were published from 2015 to 2020. The molecular targets or pathways of the effects of Rb₁ on these diseases are referring to HMGB1, GLUT4, 11β-HSD1, ERK, Akt, Notch, NF-κB, MAPK, PPAR-γ, TGF-β1/Smad pathway, PI3K/mTOR pathway, Nrf2/HO-1 pathway, Nrf2/ARE pathway, and MAPK/NF-κB pathway. The potential effects of Rb₁ and its possible mechanisms against diseases were further predicted via Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and disease ontology semantic and enrichment (DOSE) analyses with the reported targets. This study provides insights into the therapeutic effects of Rb₁ and its mechanisms against diseases, which is expected to help in promoting the drug development of Rb₁ and its clinical applications.

Background: Ginsenoside Rg₁ (Rg₁) is one of the main active components in Chinese medicines, Panax ginseng and Panax notoginseng. Research has shown that Rg₁ has a protective effect on the cardiovascular system, including anti-myocardial ischemia-reperfusion injury, anti-apoptosis, and promotion of myocardial angiogenesis, suggesting it a potential cardiovascular agent. However, the protective mechanism involved is still not fully understood. Methods: Based on network pharmacology, ligand-based protein docking, proteomics, Western blot, protein recombination and spectroscopic analysis (UV-Vis and fluorescence spectra) techniques, potential targets and pathways for Rg₁ against myocardial ischemia (MI) were screened and explored. Results: An important target set containing 19 proteins was constructed. Two target proteins with more favorable binding activity for Rg₁ against MI were further identified by molecular docking, including mitogen-activated protein kinase 1 (MAPK1) and adenosine kinase (ADK). Meanwhile, Rg₁ intervention on H9c2 cells injured by H₂O₂ showed an inhibitory oxidative phosphorylation (OXPHOS) pathway. The inhibition of Rg₁ on MAPK1 and OXPHOS pathway was confirmed by Western blot assay. By protein recombination and spectroscopic analysis, the binding reaction between ADK and Rg₁ was also evaluated. Conclusion: Rg₁ can effectively alleviate cardiomyocytes oxidative stress injury via targeting MAPK1 and ADK, and inhibiting oxidative phosphorylation (OXPHOS) pathway. The present study provides scientific basis for the clinical application of the natural active ingredient, Rg₁, and also gives rise to a methodological reference to the searching of action targets and pathways of other natural active ingredients.
