Diseases caused by air pollution and abnormal climate are occurring worldwide due to global warming. Accordingly, the international community has established a strategy to respond to climate change, and major countries have shifted their economic policies to eco-friendly industries. In this study, we investigate the current status of the renewable energy industry and that of responses to carbon neutrality and PM2.5 (air pollution) in the three major Northeast Asian countries of Japan, Korea, and China, covering changes in the corporate perceptions of Environment, Social, Governance and RE100. In more detail, the three major Northeast Asian countries, referred to as the climate villains in the international community, explain the importance of successful entry into the electric vehicles (EV) industry for a rapid transition to an eco-friendly industry. Moreover, we study the application of lightweight materials for vehicles to improve mileage in the EV industry and technical problems to be solved in the future.

The digital age start in earnest with the widespread use of the Internet. As a digital product, virtual idols bring new value to the design and dissemination of commercial brand images. "Luo Tianyi" is the world's first avatar and VOCALOID voice bank of Chinese. It has a large number of fans in China and is widely used in brand promotion. Therefore, "Luo Tianyi" is taken as the research object. Initially, we investigated the virtual idols through books, literature on the internet and other materials. Then we discussed semiotics and theories related to culture code brand design methodology (CCBD). After that, putting the above theories into practice, combined with brand design cases, we analyzed the strategy of virtual idols in brand promotion and dissemination, at last, we have the conclusion as followed. The results show that the virtual idols, visual symbol of "Luo Tianyi" can express the Index and Symbol corresponding to the brand information according to the characteristics of the brand. As an image of cultural code, "Luo Tianyi" can present three visual images at the same time, which are contemporary, traditional and future. In addition, these three visual images are presented in a strong and weak combination, which has a positive impact on the visual communication of the brand.

Drawing on mere exposure effect, we proposed that more exposure to a city, as measured by the number of channels of exposure, would increase familiarity, city image, and intention to visit that city. We conducted a survey of university students in seven Asian countries, asking them about a total of 14 cities, at least one from each of the surveyed countries. Exposure was found to be a significant antecedent and was most powerful when mediated by familiarity. Some types of exposure were stronger than others. Personal exposure, in the form of having visited a city or knowing someone who has, was the strongest type of exposure, with more than double the effect of media exposure. Social media, which is difficult to classify as either personal or media, was assessed separately and had a much smaller effect. The mere exposure effect exists whether the intention to visit a city is related to pleasure (tourism) or business.

After a loss of coolant accident (LOCA) in the prestressed concrete containment vessels (PCCVs) of nuclear power plants, the coupling of temperature and pressure can significantly affect the mechanical properties of the PCCVs. However, there is no consensus on how this coupling affects the failure mechanism of PCCVs. In this paper, a simplified finite element modeling method is proposed to study the effect of temperature and pressure coupling on PCCVs. The experiment results of a 1:4 scale PCCV model tested at Sandia National Laboratory (SNL) are compared with the results obtained from the proposed modeling approach. Seven working conditions are set up by varying the internal and external temperatures to investigate the failure mechanism of the PCCV model under the coupling effect of temperature and pressure. The results of this paper demonstrate that the finite element model established by the simplified finite element method proposed in this paper is highly consistent with the experimental results. Furthermore, the stress-displacement curve of the PCCV during loading can be divided into four stages, each of which corresponds to the damage to the concrete, steel liner, steel rebar, and prestressing tendon. Finally, the failure mechanism of the PCCV is significantly affected by temperature.

The results of the researches in the wig and the Boyo are as follows. The wig is to be classified into Bu, Pyun, Chah, Cheh, and kwik, Bu is an ornamental hairpin used by the empress, and it is decorated with Boyo. Pyun is a wig made of braided hair. Chah is made of Bal which is put together by its lenath, and it was also called Picheh or Pisuck. It is made, one by one, of hair of the convicts and the low-class people. 초도 has a meaning of toupee, and it is used to look beautiful with its thick black hair. Kwik is a wig made of hair as if it is weaved out of thread, and it is rounded with a wire. In ancient times, it was also called chah, Pi, or Pi People wore different wigs according to their class and the use, in order of Bu, Pyun, and Chah. There are remains of the Han Dynasty. Boyo, just like the wig, was originally a custom of the northern nomadic tribes which had been introduced to the later Han Dynasty. It is also called Cho Song and has a different meaning from the Boyo attached to a crown before the Han Dynasty. It became much more beautiful in the Which in period. Boyo gained its popularity by the women in Tang Dynasty, which is due to the influence by the customs of the western Ho tribe. The name of hairstyling using wigs in each period, and things such as hair, black thread, lignum, and paper were used as materials. Since the wig had differed according to the disparity in social standing it was prohibited to the general public, but it became in style later on. Wig also becomes popular in central Asia and gained its properity in the Tang Dynasty which is greatly influenced by the western countries. It is said in the records that the kobal Style had been exceedingly in fashion from the Ju to the Chung Dynasty, and the remains of the Han and Song Dynasty were found. times, it was also called chah, Pr, or period, and things such as hair, black thread, lignum, and paper were used as materials.

우석 황종하(우석(友石), 인왕산인(仁王山人) 황종하(黃宗河) 1887-1952), 우청 황성하(又淸, 黃成河, 1891-1965), 국인 황경하(菊人, 黃敬河, 1895-?), 미산 황용하(美山 黃庸河, 1899-?)는 네 살 터울의 형제들이며 모두 서화가로 이름을 남겼던 인물들이다. 이들은 특별한 교육기관에 몸담지 않고 중국에서 유입된 화보나 선배 대가들의 작품을 보며 독학으로 그림 공부를 하였지만 각자 선호하는 기법과 잘 그리는 소재가 달랐다. 즉 황종하는 호랑이 그림을, 황성하는 지두화를, 황경하는 인삼도를, 황용하는 사군자화를 잘 그린 것이다. 각종 전람회나 전시회에 참여하는 태도에는 차이가 있었지만, 그들은 사형제전을 함께 개최하거나 합작도를 자주 제작하면서 형제간의 우의를 쌓아 나갔다. 특히 1922년에 그들의 고향인 개성에서 창립한 ${\ll}$송도서화연구회${\gg}$는 후배를 양성하는 교육기관이자 스스로의 작품을 소개할 수 있는 문화의 장으로 그 역할을 다하였다. 이렇듯 황씨 사형제는 서로의 생각과 취미를 공유할 수 있었던 친구들이였고, 동시에 각자 개성 있는 작품세계를 펼쳤던 예술가였다. 그리고 구한말에 태어나 역사의 격변시기를 경험하면서도 전통 한국화의 맥을 지켜왔고, 타계할 때까지 평생 지필묵을 고집하면서 글을 짓고 그림을 그리며 화제를 썼던 작가들이었다.

This paper investigates sixteen rock-cut arhat images of the Koryo period at Sungbul-sa (成佛寺) in Chunan (天安), South Chungchung Province. These images, together with a Buddha triad in the center, are carved in thin relief on the large granite wall ($375cm{\times}248cm$), and below them is engraved a huge lotus petal which looks to be supporting all the images above. According to extant textual sources, arhats were popularly worshipped in the Koryo period. The Painting of Five Hundred Arhat Images was brought to Koryo from Later Liang (後梁) of the Five Dynasties (五代) in 923. From that time on, the cult of arhat had become gradually known in Koryo. More than thirty ceremonies worshipping arhats (羅漢齊) were officially held in Koryo court. The Sixteen Arhat images (十六羅漢像) were enshrined in many temples. In Boje-sa (普濟寺), which kings and aristocrats often visited for ritual ceremonies, had its main hall dominated by the Five Hundred Arhats, called Nahan-pocheon (羅漢寶殿). However, a limited number of arhat images of the Koryo period, originally made as sets of sixteen or five hundred arhats, are now extant. The Sixteen Arhat images at Sungbul-sa are unique examples that show all sixteen images in situ. The Sixteen Arhat images, though some of them are abraded, show various postures and gesture. One of them sits with his knee bent, and one arhat is sitting on a chair with his hand held upward. Each image is carved in a niche, just as the arhat images of Northern Song China are normally represented in niches of a cave, and are quite similar in style to the arhat images of the Northern Song period at Qinglindong (靑林洞) cave, Feilaifeng (飛來峰), Zejiang province (浙江省). This similarity between the arhat images of Sungbul-sa and those of Qinglindong certifies the strong impact of Song Buddhist art on Koryo frequently mentioned in texts. The Sixteen Arhat images surround the central Buddha raising his hand up to his chest. This Buddha triad could be ascribed to be either the Maitreya Buddha triad or the Sakyamuni Buddha triad based on the Lotus Sutra (妙法蓮華經). Still, the Sakyamuni Buddha triad was more often represented with sixteen or five hundred arhats in the Koryo period, as was seen in the record of Boje-sa where the Sakyamuni triad was enshrined with five hundred arhat images. The Sixteen Arhat images of Sungbul-sa arc most likely to be a rare example of Koryo Arhat images showing the Sakyamuni Buddha triad and the Sixteen Arhats who were predicted to be Buddhas by Sakyamuni in the Lotus Sutra.

Rhus chinensis is a shrub widely distributed in Asia. It has been used for traditional medicine and ecological restoration. Here, we report the complete chloroplast genome sequence of two R. chinensis genotypes collected from China and Korea. The assembled chloroplast genome of Chinese R. chinensis is 149,094 bp long, consisting of a large single copy (97,246 bp), a small single copy (18,644 bp) and a pair of inverted repeats (16,602 bp). Gene annotation revealed 77 protein coding genes, 30 tRNA genes, and 4 rRNA genes. A phylogenomic analysis of the chloroplast genomes with 11 known complete chloroplast genomes clarified the relationship of R. chinensis with the other plant species in the Sapindales order. A comparative chloroplast genome analysis identified 170 SNPs and 85 InDels at intra-species level of R. chinensis between Chinese and Korean collections. Based on the sequence diversity between Korea and Chinese R. chinensis plants, we developed three DNA markers useful for genetic diversity and authentication system. The chloroplast genome information obtained in this study will contribute to enriching genetic resources and conservation of endemic Rhus species.
