Liquid organic hydrogen carriers (LOHC) are recently recognized as an attractive solution for H2 storage and transportation. Among several challenging tasks for practical application, the most stringent limitations stem from the dehydrogenation reaction requiring high temperatures thermodynamically. Unlike previous reviews focusing on the LOHC concept, LOHC molecules, and process integration, this review highlights the state-of-the-art catalysts reported for the dehydrogenation of homocyclic and heterocyclic LOHC molecules. In the conversion of heterocyclic LOHC, Pd-based catalysts overnumbered Pt-based ones owing to preferential adsorption of heteroatoms onto the Pd surface. However, because of low stability of C-heteroatom bonds, catalyst development needs to concentrate on inhibiting the generation of byproducts while maintaining superior performance under mild conditions. In the case of homocyclic LOHC, Pt is overwhelmed in single metal and bimetallic catalysts owing to pronounced C-H bond cleavage. Nevertheless, the ability of Pt in C-C bond cleavage should be diminished for higher H2 selectivity, better catalyst stability, and steady LOHC recyclability, which is possible by tuning electronic and geometric effects of main active metals, as well as adding metal promoters. Consequently, great efforts will be diversely devoted to achieving an active and stable dehydrogenation catalyst for future LOHC demonstration.

조선소 강재적치장에 입고된 선반용 후판은 오버헤드 크레인을 이용한 반복적인 선별 작업을 통해 강재 절단 일정에 따라 재적치된 후 가공 공장으로 출고된다. 본 연구에서는 병렬적으로 선별 작업을 수행하는 두 대의 오버헤드 크레인을 대상으로 makespan 최소화를 위한 크레인 스케줄링 알고리즘을 제안한다. 제안된 알고리즘은 강화학습 기반의 동적 스케줄링 방법론을 적용하여 출고 시점이 불확실성을 고려한 실시간 의사결정을 지원한다. 제안된 알고리즘은 휴리스틱과의 성능 비교를 통해 크레인 간 간섭을 고려한 보다 효율적인 스케줄링이 가능함을 확인하였다.

Today, the Korean wave headed by K-pop is newly named as ‘New Korean Wave’ in that it has been extended to United States, Europe and Russia. K-POP, the main player of the new Korean wave, has been successful in SNS marketing channels. Furthermore, the content of K-pop has attracted the attention of the global audience. The media and public attention on the Korean Wave is meaningful because it is not merely a cultural export. It also makes Korean people feel national pride, seeing the mental influence of its culture on other regions. Moreover, the development of the cultural industry in our society, which is different from industrial or material development, is a proof that Korean society is at the center of globalization. Until the 20th century, Korean culture had been rather receptive than dominant. In other words, it was focused more on acceptance of other cultures than active creation or outflow of its own. Now, however, K-POP is not anymore copying Western culture. It is creating its own unique characters, which makes K-pop very competitive. Korean culture has been formed for a long time in Korea's unique historical background. Korean popular culture also has to establish a solid foothold in world markets through its distinctive and traditional feature. The positive consumer response to Korean pop culture will create the added value of Korean contents and their derivatives, which will heighten Korea’s national image also. In other words, if traditional art and K-POP are converged and equipped with our own unique and highly artistic culture, they will take the lead in the global cultural art market. In this study, we will recognize the possibility, growth and development of K-pop culture and analyze the cases of combining K-pop and Korean traditional art. First, we have to blend traditional art and other various genres to create diverse contents, and we have to actively utilize media channels. Second, we must improve people’s awareness of the copyrights of traditional art. Also, we have to mitigate the copyrights of creative dance to expand the disclosure of contents which can be utilized. Third, we have to learn about traditional arts from younger age. Fourth, we will expand traditional arts to the whole of Korean cultural policies, which can enhance the nation’s cultural value and create economic benefits. These four are expected to be effective ways to preserve the identity of traditional art and at the same time, globalize Korean culture.
