  • Architects and designers of the 20th Century made various efforts to establish new design languages reflecting the changes of society, the times, and environment. They used furniture, especially chairs, as controversial items of aesthetic value, society and ideology. Le Corbusier and Alvar Aalto are furniture designers as well as architects, who adopted this ‘spirit of the times’ actively and have greatly contributed to modernism. This study will help us to understand the diversity of design since modernism, by comparing these two designers' furniture design. It also covers the common factors In modern furniture design, and analyses their individuality and likeness In design. The following is a comparison of furniture design by Le Corbusier and Alvar Aalto. Le Courbusier linked International design and Aalto linked Rational design and Organic concept design to their furniture, just as they did in their architecture. They were able to establish the base of modern furniture design by adapting new concepts and pursuing humanism. In structure, Le Corbusier's furniture Is simple and proportional. It demonstrates a sophisticated geometric composition, mechanical beauty. On the other hand, Aalto rationally linked nature with human requirements and his furniture is organic and in harmony with geometric structure. In function, Le Corbusier's furniture is standardized and prefabricated. He designed for the user so they could choose to use the furniture efficiently to suit their needs. In comparison with Le Corbusier, Aalto Invented the ‘Stacking Chair’ which allows a more effective use of space and reflected the structure of the human body to improve the user's comfort. In materials and techniques, Le Corbusier used new materials like metal or leather, and attempted new ways such as welding, prefabrication, and standardization for production. On the contrary, Alto mainly used birch, which is the traditional material in Finland, and tried new bent wood techniques and joining methods.

  • Digital image forgery detection is one of very important fields in the field of digital forensics. As the forged images change naturally through the advancement of technology, it has made it difficult to detect forged images. In this paper, we use passive forgery detection for copy paste forgery in digital images. In addition, it detects copy-paste forgery using the L0 Norm-based LE operator, and compares the detection accuracy with the forgery detection using the existing L2, L1 Norm-based LE operator. In comparison of detection rates, the proposed lower triangular(Ayalneh and Choi) window was more robust to BAG mismatch detection than the conventional window filter. In addition, in the case of using the lower triangular window, the performance of image forgery detection was measured increasingly higher as the L2, L1 and L0 Norm LE operator was performed.

  • AB-type amphiphilic copolymers (abbreviated as LE) composed of poly (L-leucine) (PLL) as the A component and poly (ethylene oxide) (PEO) as the B component were synthesized by the ring-opening polymerization of L-leucine N-carboxy-anhydride initiated by methoxy polyoxyethylene amine $(Me-PEO-NH_2)$ and characterized. Core-shell type nanoparticles were prepared by the diafiltration method. Particle size distribution obtained by dynamic light scattering was dependent on PLL composition and the size for LE-1, LE-2 and LE-3 was $369.6{\pm}267$, $523.4{\pm}410$ and $561.2{\pm}364 nm$, respectively. Shapes of the nanoparticies observed by transmission electron microscope (TEM) were almostly spherical. The critical micelle concentration (CMC) of the nanoparticles determined by a fluorescence probe technique was dependent on the composition of hydrophobic PLL, and the CMC for LE-1, LE-2 and LE-3 was $2.0{\times}10^{-6},1.7{\times}10^{-6}$ and $1.5{\times}10^{-6}(mol/l) $, respectively. Clonazepam release from core-shell type nanoparticles in vitro was dependent on PLL composition and drug loading content.

  • CRISPR/Cas9 genome editing systems have been established in a broad range of eukaryotic species. Herein, we report the first method for genetic engineering in pyogo (shiitake) mushrooms (Lentinula edodes) using CRISPR/Cas9. For in vivo expression of guide RNAs (gRNAs) targeting the mating-type gene HD1 (LeA1), we identified an endogenous LeU6 promoter in the L. edodes genome. We constructed a plasmid containing the LeU6 and glyceraldehyde-3-phosphate dehydrogenase (LeGPD) promoters to express the Cas9 protein. Among the eight gRNAs we tested, three successfully disrupted the LeA1 locus. Although the CRISPR-Cas9-induced alleles did not affect mating with compatible monokaryotic strains, disruption of the transcription levels of the downstream genes of LeHD1 and LeHD2 was detected. Based on this result, we present the first report of a simple and powerful genetic manipulation tool using the CRISPR/Cas9 toolbox for the scientifically and industrially important edible mushroom, L. edodes.

  • A chitinolytic bacterium having a strong antagonistic activity against various pathogens including Phytophtora capsici was isolated from rhizosphere soil, and identified as Lysobacter enzymogenes (named as LE429) based on 16S rRNA gene sequence analysis. This strain produced a number of substances such as chitinase, ${\beta}-1$, 3-glucanase, lipase, protease, gelatinase and an antibiotic compound. This antibiotic compound was purified by diaion HP-20, sephadex LH-20 column chromatography and HPLC. The purified compound was identified as phenylacetic acid by gas chromatography-electron ionization (GC-EI) and gas chromatography-chemical ionization (GC-CI) mass spectrometry. In field experiment, pepper plants were treated by the strain LE429 culture (CB), neem oil solution (NO), combination (CB+NO) or control (CON). Plant height and number of branches, flowers and pods of pepper plant in CB treatment were generally highest, and followed by CB+NO, CON and NO. The fungal pathogens were strongly inhibited, while several insect pests were discovered in CB treatment. Any insect pests were not found, while all fungal pathogens tested were not suppressed in NO treatment. However, in CB+NO treatment, non incidence of fungal pathogens and insect pests were found. The strain LE429 producing secondary metabolites with neem oil should be a potential agent to control fungal diseases and insect pests.

  • This study aimed to assess the feasibility of composting spent mushroom substrate (SMS) materials of Lentinula edodes (Le), Hericium erinaceus (He), and Pleurotus ostreatus (Po). The different SMSs were composted for 7 to 10 days at high temperatures over 50℃; the composting procedure was completed in 30 days. A maturity test was conducted using the radish seed germination index and CoMMe-100. The composted SMS (CSMS) from Le and He showed gemination indices of 130% and 81%, respectively, that satisfied the criteria of maturity standard (gemination index over 70%) and the CoMMe-100 analysis. The physicochemical changes of CSMSs included an increase in the pH range from 4-5 to 6-7, slight reduction in the EC to 1-1.4 dS/m, and an organic content of 36.9% in LeCSMS. In LeCSMS, the contents of N, P, and K were 1.2%, 2.3%, and 0.77%, respectively, and heavy metals were detected below the standard value in all CSMSs; the Ca and Mg contents in the CSMSs were increased from 30% to 60% when compared to those in the SMSs. The C/N ratio (from 26-33) in LeSMS and HeSMS decreased to 15.3-15.9 in CSMSs. The growth effect of LeCSMS treatment on pepper seedlings was 60% higher than that in the control groups, one of which was treated with commercial organic compost; the former showed a superior growth effect on the leaf width, leaf length, and leaf number compared to other control groups. In conclusion, LeCSMS and HeCSMS could be utilized as compost resources capable of efficient soil amendment and plant growth promotion.

  • The purpose of this research is to analyze the influence and legacy of Le Corbusier, who has been neglected in the past discourse of landscape architecture, on the formation of modernism in landscape architecture. The research examined the relationship between Le Corbusier's ideas and practices and modern landscape architecture in three parts. The first part analyzed chronologically the relationship between architecture and landscape in Le Corbusier's theories and practices. The evaluations and criticisms of Le Corbusier's landscape practices were also examined. The second part analyzed the relationship between Le Corbusier and European Modernism in landscape architecture and his influence on European modern landscape architects focusing on Vera, Lurcat, and Canneel-Claes. The third part looked into Le Corbusier's influence on American and British modern landscape architects including Tunnard, Chruch, Rose, Eckbo, and Kiley. The result of the research showed Le Corbusier's works and theories heavily influenced important landscape architects in Europe and America, who played key roles in forming Modernism in landscape architecture. Rather than introducing Le Corbusier's Modernism theory into the discourse of landscape architecture without questioning, modern landscape architects accepted his theory and practice of Modernism selectively with praise as well as criticism. Canneel-Claes, Turnnad, and Eckbo were the pioneers who tried to establish the basis of Modernism in landscape architecture by positively accepting Le Corubiser's thoughts on Modernism; whereas, Steel and Rose criticized Le Corubiser's attitude on landscape architecture. Church and Kiely were indirectly influenced by Le Corbusier in forming their Modernism style.

  • Objective : Lithospermum Erythrorhizon (LE) has been used as an anti-bacterial and anti-inflammatory agent. However, it is unclear that LE aqueous extract could show the anti-inflammatory effects in RAW 264.7cells. The purpose of this study was to investigate the anti-inflammatory effect of aqueous extract from LE on lipopolysaccharide (LPS) - induced inflammatory response. Methods : To measure out the cytotoxicity of LE, we performed the MTT assay. To evaluate the anti-inflammatory effects of LE, we examined the inflammatory mediators such as nitric oxide (NO), prostaglandin E2 ($PGE_2$) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-${\alpha}$, interleukin, (IL)-$1{\beta}$ and (IL)-6) on RAW 264.7 cells. We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B (NF-${\kappa}B$) activation by western blot. Results : Aqueous Extract from LE itself did not have any cytotoxic effect in RAW 264.7 cells. Aqueous extract from LE inhibited LPS-induced productions of inflammatory mediators such as NO, $PGE_2$, and pro-inflammatory cytokines including TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 in RAW 264.7cells. In addition, LE inhibited the phosphorylation of p38 kinases (p38), c-Jun $NH_2$-terminal kinase (JNK), and NF-${\kappa}B$ activation in RAW 264.7 cells. Conclusion : LE down-regulated LPS-induced production of inflammatory mediators through the inhibition of p38, JNK and NF-${\kappa}B$ activation. Taken together, these results could provide the evidence for the anti-inflammatory effects of LE. Therefore, LE may be a novel target in the management of inflammation and help to support a potential strategy for prevention and therapy of inflammatory diseases.
