We selected literature from the core collection of the Web of Science (WOS) database as the research object and used visualization bibliometric software to analyse the 1313 collected studies. We found that the research on the graphene-based adsorption of heavy metals from wastewater has received widespread attention in various countries around the world, especially developing countries, since 2015, and Chinese researchers have made significant contributions. The adsorption mechanisms, adsorbent materials, and advanced adsorption techniques for the removal of heavy metals from wastewater by graphene have been the focus and hotspots in the research in this field in recent years. Heavy metal removal from wastewater with graphene has strong application potential. In the future, researchers in this area can focus on exploring issues such as “new materials,” “recyclability,” and “interdisciplinarity” to break through existing technological bottlenecks, supplement the technical research and development of graphene materials, and promote advances in this field.

Biomass porous carbons derived from Laminaria japonica were prepared by KOH and H3PO4 activation methods, respectively. The results indicated that the chemical activation had an apparent effect on the molecular framework and space of materials. To enhance the selective adsorption for organic acids, biomass carbons were modified by dopamine combined with N-(2-aminoethyl)-3-aminopropyltrimethoxysilane. The SEM and BET results illustrated the effect of the chemical activation approach on the morphology and porous texture. The biomass porous carbon using KOH activation method had the highest surface area (up to 1558 m2/ g). Compared with unmodified materials, the modified materials showed higher adsorption capacity for organic acids (27.90 μg/mL for chlorogenic acid and 25.47 μg/mL for caffeic acid). It was suggested that modification of porous carbons might be a viable pathway to increase the specific adsorption affinity and efficiency for organic acids in dried jujube samples.

인체 ‘자연법칙훈련’은 무용수에 대한 신체 훈련 및 신체 기 술 훈련이 더 이상 유일한 교학 목적이 아니라 과학적으로 사 람 신체의 전반적인 체험의 획득을 중시한 것이다. 이론과 실천의 일체화인 ‘현대무용 창작 실습수업’에서 무용 수의 창의력에 대한 유도는 ‘호흡, 동작과 상상’으로 일관해야 한다. 이러한 신체의 훈련과 체험을 통해 몸과 마음이 서로 부 합함으로 미(美)의 예술 체험을 얻을 수 있다. 이로 우샤오방 (吴晓邦)의 ‘전면적 인재육성’ 무용 교수법의 핵심 관점을 연구 분석하였다. 이는 많은 무용수(교육에 종사하는 무용수)들에게 방향을 제 시하여 과학적이고 체계적인 참고자료를 제공할 것이다.

모고사무(毛古斯舞)는 상서 토가족(湘西土家族)에서 가장 오랜 역사를 가진 독특한 무용으로 인물ㆍ대화ㆍ플롯과 일정한 퍼포먼스 격식을 갖춘 집단적 민간 무용이다. 가장 원시적인 무용으로 모고사무는 예술ㆍ문화ㆍ종교ㆍ민속ㆍ역사적 가치가 깊이 함축되어 있어 ‘중 국 무용의 산화석’으로 삼고 있다. 철저하고 세밀한 현장연구를 바탕으로, 상서 토가족 모고사무를 대상으로, 구술사의 연구적 시각에서 현지를 방문하여 취재하였다. 토가족 모고사무의 전승인과 관련된 목격자의 구술 내용을 관련 문헌 기록과 상호 비교를 통해, 시대의 변천 속에서 상서 토가족 모구사무가 예로부터 지금까지의 역사적 궤적, 다종 예술 원소와 완벽한 결합, 독특하고 고정된 무대 이미지에 대해 발굴ㆍ조사ㆍ정리하였다. 그리고 새로운 시대의 격류 속에서 계 속 생존하기 위해 시대와 더불어 발전하는 시대적 특징과 전통의 융합을 제시하였다. 건전한 전승인 육성 메커니즘을 보호 및 수립하여 재정적인 투자를 확대하고, 뉴미디어 플랫폼을 통해 전승ㆍ발전과 발양 혁신을 서로 결합하는 비전을 목적으로 토가족의 모고사무를 더 잘 전승하고 선양하기 위한 참고를 제공하려는 데 있다.

With the tremendous development of social media in recent years, luxury brands have welcomed social media with open arms as a means to engage with their customers. How luxury brands can make good use of social media marketing strategy is a top priority for both academicians and partitions but has not been well investigated. Many significant research gaps are present in this area warranting further explorations. For example, there is little research on the effectiveness of celebrity endorsement on social media (except for Chung and Cho’ (2017) study), even less for luxury brands. In addition, previous research on social media marketing mainly focuses on western-based platforms such as Facebook and Twitter. Given the mentioned research gaps, this study builds on social media marketing and celebrity endorsement literature and aims to investigate the key factors influencing the effectiveness of celebrity-based social media marketing efforts for luxury brands. In particular, China market and Sina Weibo are selected as our research setting. We propose the message characteristics, celebrity characteristics, celebrity-brand relationship and brand characteristics have impact on customer engagement in celebrity-based social media marketing activities. We combined two data sources to generate the key variables. First, we derived posts on the brand pages of 12 luxury brands (e.g., Cartier, Tiffany, BVLGARI and PIAGET) that were published on Sina Weibo from September 2016 to March 2017 on the middle of December 2017. Then celebrity-related posts were all picked out. The final sample includes more than five hundred celebrity-related brand posts. For each post, it contains three kinds of engagement measures (i.e., the number of Likes, Retweets and Comments) observed on Sina Weibo. They are dependent variables in our model. We built up regression models to test the hypotheses. To generate those variables that cannot be derived directly from the posts, a set of independent coders was recruited to quantify those variables. The exploratory results show that posts related to celebrities (e.g., brand ambassador/spokesman) take a significant part of posts on Sina Weibo brand pages.
