  • A cordycipitoid fungus infecting Hepialidae sp. in Nepal was supposed to be identical to Cordyceps liangshanensis, originally described from southwestern China, and thus, transferred to the genus Metacordyceps or Papiliomyces in previous studies. However, our multi-gene (nrSSU-nrLSU-tef-1α-rpb1-rpb2) phylogenetic and morphological studies based on the type specimen and additional collections of C. liangshanensis revealed that the fungus belongs to the genus Ophiocordyceps (Ophiocordycipitaceae). Therefore, a new combination O. liangshanensis was made, and a detailed description of this species was provided.

  • 'Yeeun' an Asiatic hybrid lily was released in 2005 at National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Suwon, Korea. The cross was made in 1994 between Liliium Asiatic 'White Bird' white colored, and Liliium Asiatic 'Cote d'Azur', pink colored variety. It was preliminarily selected as 'A96-5' in 1996. Multiplication and bulbing, and characteristic tests were conducted from 1997 to 2004. The evaluation of characteristics was investigated as 'Wongyo C1-21' in 2004 at Suwon. 'Yeeun' flowers in the end of June and grows 41.6 cm stem length. Flowers are upward-facing, unspotted in petals and yellow green (RHS, 18C). Year-round flowering can be by storing the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. It is needed to control Botrytis disease in wet season.

  • In this study, the sintering mechanism of woodceramics (WCs) from cashew nut shell waste (CNSW) was studied by analyzing chemical reactions and structural changes during the sintering process of of CNSW powder, liquefied wood and green bodies of WCs at $900^{\circ}C$ for 60 minutes in the $CO_2$ atmosphere. The chemical and structural properties of the products were investigated by X-ray diffraction (XRD), Raman spectroscopy, Fourier Transform Infrared (FTIR), and scanning electron microscope (SEM). The results showed that the decomposition reactions of liquefied wood and CNSW occurred simultaneously to form the hard carbon and the soft carbon at high temperature. The sintering mechanism of WCs has been presented.

  • The Republic of Korea (ROK) has had a successful experience in greening its land because of strong state policy and public participation. This paper aims to analyze the interest positions, participation, and accountability of multiple actors in the process of greening movements in the ROK. These movements were divided into two phases: forest rehabilitation (1973-1997) and urban greening (1998-2017). During the first phase, farmers caused deforestation by slash-and-burn farming and illegal logging, and governmental agencies acted as helpers controlled the farmers' deforestation activities. During the second phase, government agencies and enterprises caused deforestation with urban development projects, including construction of housings and roads. Multiple actors including citizens, NGOs, and enterprises helped urban greening through campaigns, donations, and monitoring. As a result, managing interest positions is significant to motivate multiple actors to participate in the greening movement. Participation with clear accountability is meaningful for successful greening. Therefore interest-based participation requiring accountability contributes to greening. This phenomenon indicates interconnection for interest positions, participation and accountability should be considered in designing greening policies.

  • Recently, ESG bond issuance has been gradually spreading to banks and non-financial private companies in Korea. However, the Korean ESG bond market is still in its infancy in terms of size, diversity and investor base compared to the global ESG bond market. In other words, ESG bonds are rapidly forming in the global market, but are still in the formation stage in the domestic market, and various policy and practical measures such as system, incentives, and infrastructure are needed to activate them. In this paper, we examine the domestic and international status of ESG bonds in relation to responsible investment. In addition, this paper explores specific measures to revitalize the domestic ESG bond market in four aspects: establishing ESG bond standards, procedures and regulations, increasing ESG bond investment demand, increasing ESG bond issuance, building market infrastructure and market efforts. This study is expected to contribute to the development of the domestic ESG bond market and responsible investment.

  • A new type of precast steel reinforced concrete (PSRC) column was put forward in this paper. In order to study the static performance of PSRC column and hollow precast steel reinforced concrete (HPSRC) column subjected to combined compression and shear loading, a parametric test was carried out and effects of axial compression ratio, concrete strength and shear ratio on the mechanical behavior of composite PSRC column and HPSRC column were explored. In addition, the cracks development, load-span displacement relationship, strain distribution and shear bearing strength of column specimens were emphatically focused. Test results implied that shear failure of all specimens occurred during the test, and higher strength of cast-in-place concrete, smaller shear ratio and larger axial compression ratio could lead to greater shear resistance, but when the axial compression ratio was larger than 0.36, the shear capacity began to decrease gradually. Furthermore, truss-arch model for determining the shear strength of PSRC column and HPSRC column was proposed and the calculated results obtained from proposed method were verified to be valid.

  • This paper examines the current status of the Korean tea culture industry and explores ways to restore and develop Korean tea culture by referring to the responses of the neighboring countries of China. In order for the Korean tea industry and tea culture to expand, based on a strong tea industry, high-quality tea should be created to satisfy consumers' needs, health, convenience, and reasonable prices, and effective promotion and marketing should be carried out. In addition, it is necessary to reinterpret the traditional tea house and inherit the spirit of tea.

  • Color conversion layer refers to a layer that converts the blue light emitted from the backlight into the red and green light. Heavy metal-free quantum dots and perovskite nanocrystals have attracted great attention as base materials for color conversion layers due to their outstanding optical characteristics. Here, we review recent advances in the development of color conversion layers based on quantum dots. First, we overview the representative optical characteristics of quantum dots and perovskite nanocrystals, and then introduce printing techniques for color converting layers including photolithography, inkjet printing, and nanoimprinting. Finally, we conclude this review with a brief perspective.

  • Objectives: The coronavirus disease 2019 has deteriorated mental health, particularly in mothers with elementary school children. Although the country has developed several health promotion programs to preserve mental health, no program has incorporated Korean medicine. Thus, this study focuses on developing vital Korean medicine mental health care programs. Methods: The program follows the Korean medicine health promotion program principles. Guidelines, reports, research, and previous programs were analyzed to form interventions and lecture content. Results: Pellets, hot packs, meditation, lavender oil, and green tea were selected as final intervention strategies. Mental health-related guidelines were analyzed to produce stress management lecture materials. In addition, an operational methods and evaluation tool manual was created. Conclusion: We designed a health promotion program capitalizing on Korean medicine to improve mental health. This program will be assessed and accordingly improved through practical applications.
