Deploying new and renewable energy should be encouraged due to scarce of natural resources and to reduce the $CO_2$ emission. Regarding the Green Building Certification System, '2.2.1 new and renewable energy use', and '2.3.1 carbon dioxide emission reductions' are related to new and renewable energy. Applying new and renewable energy can achieve the score in two criteria mentioned above and most of buildings get a perfect score in the green building certification system. So these criteria needs to be revised to have discrimination. In this study, supply rate of new and renewable energy of the buildings that have achieved Green Building Certification by E Green Building Certification Institute was analyzed. The improvement of assessment criteria related to new and renewable energy is proposed and could be applied to the revisions.

Current international negotiation and cooperation for sustainable development are focused on three main themes. The first theme is implementation of Sustainable Development Goals (SDGs). The second theme is development of measures for climate change. The third theme is sustainable management of biodiversity and ecosystem services. In South Korea, responses of government policies and academic studies have been predominantly to one of these three themes. There have not been many integrated efforts to develop countermeasures considering all three international themes. In addition, while "green growth" policies have been setting national agendas for Korea's sustainable development, they must be scrutinized such as why they have not dealt with some parts of these three themes and whether they have ignored one of these themes due to lack of integrated responses. This study finds critical issues in South Korea on how to harmoniously respond to the three themes of international efforts and improve green growth policies. First, to achieve SDGs, the domestic statistical system must be reorganized to track the achievement of "inclusiveness" and "green growth". Second, the climate change response policy should seek inclusion between countries and between social groups. Third, in the field of biodiversity and ecosystem services, it is necessary to establish Korea's identity in global geopolitics and enhance its own traditional ecological knowledge. Fourth, it is necessary to consider how to solve discrepancy between climate change response policies and biodiversity-ecosystem service management policies. Finally, proactive improvement of laws and institutions must occur to promote inclusive green growth.

The green synthesis of inorganic nanoparticles (NPs) using biomaterials has garnered considerable attention in recent years because of its eco-friendly, non-toxic, simple, and low-cost nature. In this study, we synthesized NPs of noble metals, such as Ag and Au using an aqueous extract of a marine seaweed, Ecklonia cava. The formation of AgNPs and AuNPs was confirmed by the presence of surface plasmon resonance peaks in UV-Vis absorption spectra at approximately 430 and 530 nm, respectively. Various properties of the NPs were evaluated using characterization techniques, such as dynamic light scattering, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis. Phytochemicals in the seaweed extract, such as phlorotannins, acted as both reducing and stabilizing agents for the growth of the NPs. The green-synthesized AgNPs and AuNPs were found to exhibit high catalytic activity for the decomposition of organic dyes, including azo dyes, methylene blue, rhodamine B, and methyl orange.

We report the feasibility of TaC production via self-propagating high temperature synthesis, and the influence of the initial green compact density on the final composite particle size. Experiments are carried out from a minimum pressure of 0.3 MPa, the pressure at which the initial green body becomes self-standing, up to 3 MPa, the point at which no further combustion occurs. The green density of the pellets varies from 29.99% to 42.97%, as compared with the theoretical density. The increase in green density decreases the powder size of TaC, and the smallest particle size is observed with 1.5 MPa, at $10.36{\mu}m$. Phase analysis results confirm the presence of the TaC phase only. In the range of 0.3-0.5 MPa, traces of unreacted Ta and C residues are detected. However, results also show the presence of only C residue in the matrix within the pressure range of 0.6-3.0 MPa.

The Go-Chang county in Jeon-Buk province has been progressed the diversified agricultural crops production region. The Go-Chang county is known as the famous cultural tour place that has the many historical and cultural resources (provincial natural park, traditional music, great stone cluster area, military castle walls, good tasted eel food and wine). But, today, the circumstances of global agricultural free trading situations is rapidly proliferated, it invited the depression of the agricultural incomes in rural regions in Korea. So, the Go-Chang county seeks trying to alternative development methods. The new frontier like scenic landscape agriculture is the one of the innovative strategies in this processes. The Go-Chang county selects and supports the scenic landscape agriculture for the new income production policy in connection with the green tourism. This study finds out the important components of the success of a scenic landscape agriculture for the introduction to the new frontier of peen tourism in Go-Chang county. First the scenic landscape agriculture development must be related the 4 season-ecological cultivation methods connected well-being trends. Second, it will be increased the income level of rural people by the competitive the rural green products and diversified green tourism programs which produced by the efforts of the rural people.

Two Tobamoviruses, Cucumber green mottle mosaic virus (CGMMV) and Zucchini green mottle mosaic virus (ZGMMV), occurred in Korea in 463 ha in 1998, 33.9 ha in 1999, and 44.2 ha in 2000. CGMMV was detected in watermelon, cucumber, oriental melon, and melon, whereas ZGMMV was mainly detected in zucchini squash. Thirty-six CGMMV isolates wee classified into three types by analysis of single strand cDNA conformational polymorphism (SSCP) of the coat protein gene. In a comparison of serological relationships among CGMMV, ZGMMV, and Kyuri green mottle mosaic virus (KGMMV), the three tobamoviruses specifically reacted with each homologous antibody in the double-antibody sandwich enzyme-linked immunosorbent assay and rapid imunofilter paper assay (RIPA), although ZGMMV and KGMMV were slightly biologcially similar. In a survey of the three tobamoviruses in cucurbitgrowing field in Korea by RIPA, CGMMV and ZGMMV were detected but KGMMV was not found in commercially growing cucurbit crops so far. Seed contamination ratio of CGMMV in bottle gourd seeds tested was 84%, while seed trasmission ratio from the virus-contaminated seeds was 2.0%. Soil transmission ratio was 0-3.5% in fields naturally infested with CGMMV or ZGMMV. Control measures of the virus diseases are roguing and sanitation. These suggest that it is important to rogue the first infected crops, which include the seed and soil, especially early in the season. This may be practicable to control the diseases because CGMMV and ZGMMV have a narrow host range restricted to cucurbitaceous crops.

This paper investigates the color rank system of the Wonsam, ceremonial topcoat, worn as a court formal costume of the Joseon dynasty by analyzing the court costume system and the actual examples of wearing. The research shows that there were some discrepancies of the color rank of the Wonsam between the court costume system and the actual wearing examples. There were red, purple, blue, green, and black Wonsam in the Joseon dynasty. The color rank of the Wonsam is as follows: the Queen's color was red, the Crown Princess's was green and purple, the royal concubine's was usually green and blue, but they could wear purple when they won the King's favor. A prince's wife's was usually green, but she wore blue and purple if she became the mother of the King. The princess's was green, and the court lady's was green, blue, and black. In most cases, the textiles of Wonsam were made by silk with patterns, even though Joseon dynasty was ordered to use silks without patterns in court weddings and funeral ceremonies to avoid extravagance.
