A series of ZIF-67-C-IL catalysts were prepared using ZIF-67 and 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl] imide ([ BMIM]NTf2) ionic liquid as precursors. The structure of the catalysts was characterized by XRD, TEM, SEM and XPS. The catalytic performance of the catalysts for the oxygen reduction reaction (ORR) was evaluated in a three-electrode system. The results confirmed that the high-temperature treatment of the precursors resulted in the formation of N, S codoped carbon-encapsulated Co9S8 nanoparticles. To create N, S co-doped carbon coated Co9S8 nanoparticle catalysts, ionic liquids are used as sulfur and nitrogen sources. The catalytic activity of ORR can be improved using N, S co-doped carbon to prevent the aggregation of Co9S8 nanoparticles. Graphitized and N, S co-doped carbon shells are optimal for achieving high activity stability. Optimal 600-ZIF-67-C(1:1.5)-30IL catalytic activity was observed for ORR. The half-wave potential of ORR was 0.88 V vs. RHE in 0.1 mol L− 1 KOH, with a limit current density of 4.70 mA cm− 2. Similar ORR electrocatalytic activity was observed between this catalyst and commercial Pt/C (20 wt%).

As a promising anode for sodium-ion batteries (SIBs), cobalt sulfide ( CoS2) has attracted extensive attention due to its high theoretical capacity, easy preparation, and superior electrochemical activity. However, its intrinsic low conductivity and large volume expansion result in poor cycling ability. Herein, nitrogen-doped carbon-coated CoS2 nanoparticles (N–C@ CoS2) were prepared by a C3N4 soft-template-assisted method. Carbon coating improves the conductivity and prevents the aggregation of CoS2 nanoparticles. In addition, the C3N4 template provides a porous graphene-like structure as a conductive framework, affording a fast and constant transport path for electrons and void space for buffering the volume change of CoS2 nanoparticles. Benefitting from the superiorities, the Na-storage properties of the N–C@CoS2 electrode are remarkably boosted. The advanced anode delivers a long-term capacity of 376.27 mAh g− 1 at 0.1 A g− 1 after 500 cycles. This method can also apply to preparing other metal sulfide materials for SIBs and provides the relevant experimental basis for the further development of energy storage materials.

This study examines consumer reaction to different luxury advertising information (promotion-focus vs. prevention-focus). Studies examine the relationship between consumers’ face concern and individual regulatory focus, and explore the relationship between face concern and luxury advertising type with a 2 (face concerns) × 2 (advertising information) experiment design.

This study aims to investigate the effect of word-of-mouth on the purchase of genuine and counterfeit luxury brands. It also examines the roles of attitude functions and social norm in the relationship between word-of-mouth communication and consumers’ luxury brand evaluation. A 2 (information source: advertising vs. word-of-mouth) × 2 (luxury brand: genunie vs. counterfeit) between-subjects experimental design was used to collect the data. A total of 153 adult consumers from Shanghai, China were recruited and randomly assigned to one of the four experimental conditions. Prior to the conduction of the actual experiment, a pretest of 30 respondents was conducted to determine the brands and scenarios selected for the experiments. Attitude function (social-adjustive function or value-expressive function) is measured by a self-monitoring scale. Social norm, luxury brand evaluations on genuine and counterfeit luxury brands were measured. MANOVA and ANOVA were performed to examine the proposed hypotheses. Results indicated that purchase intention for counterfeit luxury brand was moderated by subjective norm. Word-of-mouth increased the subjective norm related to the disapproval of counterfeits, compared to traditional advertising. Subjective norm was found to strongly influence consumers’ counterfeit luxury brand evaluation. The relationship between subjective norm and counterfeit consumption was positively significant. The moderating effects of self-monitoring and subjective norm on consumers’ evaluations and consumption for counterfeit luxury brands were found to significant. In short, the findings support the proposed hypotheses and showed that positive word-of-mouth was an efficient way to enhance consumers’ purchase intentions for genuine luxury brands, and also an effective means to decrease purchase intentions for counterfeit luxury brands. The results reveal that social-adjustive function and value-expressive function served by luxury brand consumption can be increased by positive word-of-mouth. Furthermore, higher levels of social-adjustive function and value-expressive function served by publicly consumed product (vs. privately consumed product) are found, indicating that product categories also affect the attitude functions served by luxury brand consumption. Managerial recommendations are provided to the marketing managers for luxury brands.

As an important cultural industry, animation, with its unique affinity and communication power, is one of the important carriers of cultural communication. It can build up the national cultural image, reflect the comprehensive strength of the country, and contribute greatly to the achievement of national brands and the aggregation of national images. It is a great tool for international communication and exchange under the background of globalization. By studying the development status of contemporary Chinese animation, analyzing the contemporary artistic characteristics of Chinese animation, this paper puts forward the methods and principles of Chinese animation creation under the construction of national cultural image, that is use animation themes to highlight the connotation of Chinese culture, improve China's recognition through role shaping, innovate scripts to tell Chinese stories and use new means to promote Chinese animation. Finally realizes the transformation and innovative development of excellent traditional ideas and values in the modern cultural context, and improves the national cultural soft power and the international influence of Chinese culture.

요즘 중한 양국 문화 영역의 합작이 심화하고 있다. '원소스 멀티테리토리'모식으로 제작한 중한 영화들을 관객의 주목을 받았다. 하지만 <용하형경>과 <극한직업>이 개봉하면서 양극화 관영 평가와 현격 한 흥행 차이가 생겼다. 따라서 본 논문에서는 두 영화를 중심으로 내러티브, 캐릭터로서 현지화 원소의 운용을 대비하고 분석한다. 같은 스토리는 어떻게 다른 나라의 현지화 사회 문화를 표현할 수 있는 것에 대해 살펴보고 더 우수한 중국 영화를 만들기 위해 현지화 원소의 활용 방법을 총결해야 한다.

지난 수십 년 동안, 변화하는 기후를 이해하기 위해 많은 연구가 있었고, 여러 기후 변량의 변화추세가 발견되었다. 이들 추세를 설명하기는 쉽지 않 고, 때로는 서로 모순적으로 보여지기도 한다. 다양한 기후 변량의 변화추세를 일반적으로 설명하기 위한 가설을 제시하기 위해 많은 시도도 있었다. 어느 정도 지식이 축적된 이 시점에서, 우리 시대에 진행되는 기후 변화에 대해 우리가 알고 있는 것을 되돌아보고 신중히 정리해볼 필요가 있다. 여기서는 기온, 일사량, 풍속, 증발, 강수에 초점을 맞추어 변화하는 기후에 대해 우리가 얻은 지식을 종합적으로 살펴보고자 한다. 온난화, 흐 려짐, 잔잔하기로 대변되는 주요 변화추세 및 증발의 역설, 강수 변동성의 증가를 서울 지점 자료를 예시로 들어 설명한다. 이러한 변화에 대한 이해를 근거로 수문학자와 공학자들에게 네 가지 함의를 제시하려 한다.

The potential antioxidant and anticancer activities of Hexane, EtOAc (Ethyl acetate), BuOH (n-Buthanol) and water fractions from methanolic (MeOH) extract of Picrasma quassioides (D. Don) Benn. were evaluated in vitro. Tested fractions showed strong antioxidant activity, especially EtOAc fraction had the highest activity (IC50 = 114.01 μg/mL), containing high total phenolics and total flavonoids contents, showed 67.59 Tan μg/mg and 64.95 Que μg/mg respectively. Anticancer activity of these fractions was tested by MTT assay on HT-29 (the human colon carcinoma cells) cell line. BuOH fraction not only showed very high anticancer activity, but also had no cytotoxic effect on 293 (the human normal kidney cells) cell line. Considering these results, we used BuOH fraction of MeOH crude extract from P. quassioides (D.Don) Benn. to do assessment of apoptosis by flow cytometry and the mRNA expression levels of widely established apoptotic-related genes on HT-29 cell line. All the experiments showed that BuOH fraction can induce apoptosis on HT-29 cell line strongly. Taken together, methanolic extract of P. quassioides has potential for antioxidant and anticancer activities products.
