Decabromodiphenyl ether (BDE209) is a persistent aromatic compound widely associated with environmental pollutants. Given its persistence and possible bioaccumulation, exploring a feasible technique to eradicate BDE209 efficiently is critical for today’s environmentally sustainable societies. Herein, an advanced nanocomposite is elaborately constructed, in which a large number of titanium dioxide ( TiO2) nanoparticles are anchored uniformly on two-dimensional graphene oxide (GO) nanosheets ( TiO2/GO) via a modified Hummer’s method and subsequent solvothermal treatment to achieve efficient photocatalytic degradation BDE209. The obtained TiO2/ GO photocatalyst has excellent photocatalytic due to the intense coupling between conductive GO nanosheets and TiO2 nanoparticles. Under the optimal photocatalytic degradation test conditions, the degradation efficiency of BDE209 is more than 90%. In addition, this study also provides an efficient route for designing highly active catalytic materials.

This paper probes the elements of theoretical necessity, starting with the word ruo (若) in Duan Yucai’s Shuo Wen Jie Zi Zhu (段玉裁《說文解字註》). From the prospective of theoretical methods of “Ruo (若) ,” the theoretical necessity of “Ruo (若) ,” the exegesis functions of “Ruo (若) ” and different intonations with different modal particles, the author conducted multi-level and multi-dimensional analysis on “Ruo (若) ” in Duan Yucai’s Shuo Wen Jie Zi Zhu (段玉裁《說文解 字註》) so as to explore the concepts of theoretical necessity from Duan Yucai.

Core–shell ZIFs wrapped CuO hybrid materials (CuO@ZIF-67(Co)) were designed, synthesized, characterized, and employed as peroxymonosulfate (PMS) activators to degrade methylene blue (MB). It demonstrated outstanding catalytic activity on account of the unique structure and the synergistic effect between CuO cores and ZIF-67(Co) shells, resulting in complete degradation of MB (10 mg/L) in 1 min. Reactive oxygen species (ROSs) research showed that both SO4 − and OH were responsible for the removal of MB. The synergistic activation mechanisms in the CuO@ZIF-67(Co)/PMS system were investigated, which mainly involved the effective electron transfer of CuO and ZIF-67(Co) for accelerating the cycle of CuII/ CuI and CoIII/ CoII. This study broadens the application of MOF-derived materials for wastewater treatment.

Background: Virtual reality (VR) programs based on motion capture camera are the most convenient and cost-effective approaches for remote rehabilitation. Assessment of physical function is critical for providing optimal VR rehabilitation training; however, direct muscle strength measurement using camera-based kinematic data is impracticable. Therefore, it is necessary to develop a method to indirectly estimate the muscle strength of users from the value obtained using a motion capture camera. Objects: The purpose of this study was to determine whether the pedaling speed converted using the VR engine from the captured foot position data in the VR environment can be used as an indirect way to evaluate knee muscle strength, and to investigate the validity and reliability of a camera-based VR program. Methods: Thirty healthy adults were included in this study. Each subject performed a 15-second maximum pedaling test in the VR and built-in speedometer modes. In the VR speedometer mode, a motion capture camera was used to detect the position of the ankle joints and automatically calculate the pedaling speed. An isokinetic dynamometer was used to assess the isometric and isokinetic peak torques of knee flexion and extension. Results: The pedaling speeds in VR and built-in speedometer modes revealed a significantly high positive correlation (r = 0.922). In addition, the intra-rater reliability of the pedaling speed in the VR speedometer mode was good (ICC [intraclass correlation coefficient] = 0.685). The results of the Pearson correlation analysis revealed a significant moderate positive correlation between the pedaling speed of the VR speedometer and the peak torque of knee isokinetic flexion (r = 0.639) and extension (r = 0.598). Conclusion: This study suggests the potential benefits of measuring the maximum pedaling speed using 3D depth camera in a VR environment as an indirect assessment of muscle strength. However, technological improvements must be followed to obtain more accurate estimation of muscle strength from the VR cycling test.

To meet the increased performance and cost requirements of commercial supercapacitor, a N and O self-doped hierarchical porous carbon is fabricated via a green and simple self-activation route utilizing leaves of wild hollyhock as raw materials. Comparing to commercial activated carbon, the reported material exhibits some marked merits, such as simple and green fabrication process, low cost, and superior capacitance performance. The specific surface area of the obtained N and O codoped hierarchical porous carbon arrives 954 m2 g−1, and the content of the self-doped nitrogen and oxygen reaches 2.64 at.% and 7.38 at.%, respectively. The specific capacitance of the obtained material reaches 226 F g− 1 while the specific capacitance of the symmetric supercapacitor arrives 47.3 F g− 1. Meanwhile, more than 90.3% of initial specific capacitance is kept under a current density of 20 A g− 1, and no arresting degradation is observed for capacitance after 5000 times cycle, perfectly demonstrating the excellent cycle and rate capability of the obtained material. The obtained N and O co-doped hierarchical porous carbon are expected to be an ideal substitution for commercial activated carbon.

Previous research has found that taking photos during travel for the purpose of sharing with others via SNS (social networking sites) induces self-presentational concerns, which can decrease engagement and enjoyment of the experience. However, the previous studies have defined travel engagement and enjoyment too narrowly and failed to consider the heterogeneity in terms of the importance of photo-taking. While some travelers are reluctant photo takers and regard taking photos as a bother, others place more importance on photo-taking than sightseeing, and may therefore find it difficult to enjoy the travel experience without taking photos. To address these deficiencies, we modeled not only negative, but also positive relationships between photo-taking and travel engagement and enjoyment. The results showed that when taking photos, travelers who regard photo-taking as important were more engaged in the experience and enjoyed it more than travelers who regarded photo-taking as less important. Thus, this study provides a theoretical contribution to research on travel engagement.

Employee innovation is critical to business success and draws knowledge and ideas from customer engagement (CE). In particular, customer interaction, a key aspect of CE, offers opportunities for, and act as a source of, hotel employees’ innovative behaviors (Jaakkola & Alexander, 2014; Li & Hsu, 2016). Focusing on the hotel industry, this study investigates the role of customer interaction, positive affect, and employee motivations in enhancing employees’ innovative behaviors. A structural model was developed based on relevant literature and pilot tested on data collected via a quantitative survey of 196 hotel employees who were in a position requiring interactions with customers. The findings provide support for the proposed model and suggest customer interaction, positive affect, and intrinsic and extrinsic motivations as influential factors impacting on employees’ innovative behaviors directly and/or indirectly. This pilot study forms the basis of a larger project modeling the customer interaction - employee innovation relationship (findings to be presented at the conference). The study contributes to the limited literature on innovation through enhancing CB and employee emotional welfare, addressing the call to strengthen research on the antecedents and outcomes of CB (So, King, Sparks, & Wang, 2016). Practically, the results highlight a need for hotels’ benefit and reward systems to incorporate measures of employee performance in relation to CB.

Ever since the notion of a sharing economy was highlighted by Time Magazine as one of the ten ideas that will one day change the world, there has been a significant increase in scholarly attention dedicated to investigating the impact sharing economies will have on individuals, organizations and society as a whole. Particularly, sharing economy has revolutionized the landscape of the tourism industry through Airbnb (Fang, Ye, & Law, 2016). Academic research has focused on studying consumption practices and behaviors from a recipient perspective, but relatively little attention has been given to understand what impacts sharing economy has, from a sharer point of view (Fagerstrøm, Pawar, Sigurdsson, Foxall, & Yani-de-Soriano, 2017). Specifically, the existing literature has yet to explore in what ways and to what extent sharers are engaged with sharing economy platforms, and explore what consequences accrue from engaging in sharing economy activities. As a result, this paper seeks to fill this gap by proposing a framework drawing on self-determination theory (SDT), in conjunction with a tourism well-being perspective to examine how sharers’ perception of extrinsic rewards indirectly influences their well-being through the mediating role of engagement in tourism sharing economy activities. Data from Airbnb hosts in London were analyzed through PLS. The findings show that hosts’ engagement with Airbnb fully mediates the relationship between extrinsic rewards and their wellbeing. In other words, extrinsic rewards from using the sharing platform have a positive effect on sharers’ engagement in sharing economy activities (Tussyadiah & Pesonen, 2016; Guttentag, 2015). In turn, engagement in sharing economy activities has been found to have a positive effect on the sharers’ well-being (Kim, Uysal, & Sirgy, 2013; Ganju, Pavlou, & Banker, 2016). The paper has some important managerial implications.

In the context of the consumption of luxury goods, WOM generation seems to be an important way for individuals to express their identity. It has long been implied that luxury goods should be “conspicuous” because, generally, individuals are motivated to consume particular goods to communicate their social identity (cf. Belk, 1988; Berger & Health 2007). However, once individuals send positive messages about a luxury good, that item may be adopted by others whom they dislike. Thus, individuals may use moderation in generating positive WOM and prevent use of their favorite luxury brands from trickling down (Berger & Ward, 2010). In this regard, recent research has examined the effects of need-for-uniqueness (NFU) on consumers’ intention to generate word-of-mouth (WOM) and suggested that high-NFU consumers are unwilling to generate (positive) WOM because WOM results in the adoption of the product and would harm the consumers’ unique image (Cheema & Kaikati, 2010). However, they have focused on only one (avoidance-of-similarity) of the three types of NFU: avoidance of similarity (AS), unpopular choice counter-conformity (UCC), and creative choice counter-conformity (CCC) (Tian, Bearden, & Hunter, 2001). The purpose of this study is to examine how different types of NFU affect consumers’ willingness to generate WOM, considering the moderating role of product domain in the relationship between NFU and WOM. We examined the effects of types of NFU and product domain on positive WOM generation using a 3 (WOM sender type: high-AS/high-UCC/high-CCC consumers) × 2 (product domain: more identity-relevant, luxury vs. less identity-relevant, ordinary goods) between-subjects experimental design. The participants were 80 university students. We selected a high-quality coat as a luxury item and a high-end flash drive as an ordinary product. The former was represented as more identity-related than the latter. The results of ANOVA showed that three types of NFU have different effects on consumer’ willingness to generate positive WOM. High-AS consumers, as well as high-UCC consumers, are more unwilling to generate positive WOM, whereas high-CCC consumers are more willing to generate WOM; moreover, these effects are more pronounced when the consumers were referencing a more identity-relevant, luxury good. The implications of this study may help firms understand the factors that elicit or prevent WOM generation.

This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g−1 and 1.17 cm3 g−1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large mesopores centered at 9.9 nm was observed. The specific capacitance of the reported materials reached up to 328 F g−1, which was 2.1 times higher than that of pristine CMK-3. The capacitance retention rate was found to be higher than 87.9% after 1000 charge/discharge cycles. The supplementary pseudocapacitance as well as the enhanced wettability and conductivity due to the incorporation of nitrogen heteroatoms within the carbon matrixes were found to be responsible for the excellent capacitive performance of the reported NOMC materials.

There has been an increasing trend of using code-switching to enhance ad persuasion among local and global brands. Ads that include two or more languages are referred to as code-switched ads (Luna and Peracchio 2005a; 2005b). It is noted that previous studies investigating code-switched ad effectiveness have focused on bilinguals, not monolinguals. Due to the emerging use of code-switching in ads in monolingual markets, more research efforts are required to understand its effectiveness and boundaries among the monolinguals. The purpose of this study is to investigate the moderating role of consumer local-global identity in the effectiveness of code-switched ads among monolinguals. Two experiments were conducted and the results confirmed our hypothesis that consumer local-global identity moderates the effect of code-switched ads. The results indicated that congruence between consumer local-global identity and code-switching enhanced persuasiveness. In addition, the mediating effect of ad involvement was identified. These findings provide managerial implications for marketers.

The present work reports a systematic study of using carboxymethylated cellulose (CMC) as water-bornebinder to produce Li4Ti5O12-based anodes for manufacture of high rate performance lithium ion batteries. When theLTO-to-CB-to-CMC mass ratio is carefully optimized to be 8:1:0.57, the special capacity of the resulting electrodes is144 mAh·g−1 at 10 C and their capacity retention was 97.7% after 1000 cycles at 1C and 98.5% after 500 cycles at5C, respectively. This rate performance is comparable or even better than that of the electrolytes produced using con-ventional, organic, polyvinylidene fluoride binder.

The aim of this paper is to apply of Quality Function Deployment for redesigning on fashion product. Quality Function Deployment is a useful tool in product development with the application of voice of customer. The findings could helps in redesigning Malaysia Batik sarong to be a better in design quality. According to Legino, 2012 and Yunus, 2013, local Batik producers in Malaysia are still producing batik sarong with printing or stamping method and freehand stylus batik using canting. This research will focus on the Batik sarong which locally produced in Kelantan and Terengganu states in Malaysia. Ismail et al. (2013) stated the batik designing activities frequency could boost up the sales performance of Small Medium Enterprises in Peninsular Malaysia. As in a Batik sarong tradition production, all the design specifications are from the ideas and creativity of the designer or the Batik producer (Yunus, 2013). The first objective of this research is to utilise the application of Voice of Customer in redesigning cultural fashion product. The customers’ feedback or known as the term ‘Voice of Customer’ could help the manufacturer to better the product before the following production. This Voice of Customer could offer a specific detailing for quality which needs to be redesigned in a product. Meanwhile, the second objective is to distinguish design specifications and characteristics using House of Quality. In product designing phase, it is crucial to identify each specification and characteristic which translated from Voice of Customer to the House of Quality matrix. This matrix would help designers to design according to qualities that customer wants for a better and successful product in a market. Quality Function Deployment is has been used in automotive industries in the decades back but now other industries are applying it as well. Golshan et al. (2012) studied on using Quality Function Deployment to detect important items influencing clothing industry in Iran focusing in men’s shirt. Meanwhile, Huang and Tan (2007) research was on how to characterise various key factors affecting apparel design and product quality. Ng and Wang (2007) explored further benefits of research collaboration between an innovative clothing-making technology and an effective design management instrument, Quality Function Deployment toward integrated products design development. Waisarayutt and Siritaweechai (2006) study about the potential of using Quality Function Deployment as a tool for product development, the communication transferred between marketing to research and development to prove Quality Function Deployment efficiency in producing sports bra in Thailand. The input that could be concluded in these researches is Quality Function Deployment could be applied to fashion product. It really helps to identify and managing a proper production process with specific technical aspects. But the challenge would be the cost and time constraint to test the results into production. The scope of this research would be limited on the Malaysia Batik sarong and the samples taken on Malaysian women consumers only. As a pilot test, a structured survey was executed with targeted sampling total the minimum of 10 and the maximum of 30 participants. It would be suffice to have the data from 10 to 30 participants to build the House of Quality model (Griffin and Hauser, 1993). The expertise opinion for matrices validation would be from the Malaysian expertise in fashion design with Malay Batik sarong knowledge. It is hope this research would indicate the customers’ requirements and production team idea could be measured and translated to a systematic data. It could be a detailed and specific technical requirement could be planned earlier before it is actually being produced. This could be a sustainable approach for a traditional product which could control the material that they use and sustain the quality as the past production. This research would help the Small Medium Enterprises design team or the designers to design a product from customers’ view and plan well. This research finding also could assist designers or batik producers to understand the consumers’ requirements in Batik sarong. The Small Medium Enterprises also could plan their sarong product using the identified specifications in the research as a starting point of research and development plan in sales and marketing strategy.

Expensive handbags, in particular, luxury designer handbags are incredibly popular among fashionable women. This is why many fashion houses such as Chanel and Hermes offer handbags as another product line as part of their accessories category (Juggessur, 2011). Some retailers claim that owning a luxury designer handbag worth more than £1,000 can make financial sense to middle-class women, who may not spend as much on clothing, but view an expensive luxury designer handbag as an investment piece which can be used every day, adding a touch of glamour (Juggessur, 2011). The global handbag market encompasses exceedingly dynamic players and an expanding consumer base, which is expected to flourish due to increasing demand from emerging markets and strong performances by the international luxury brands (Digital Luxury Group, 2013). The top 10 markets for luxury handbags, collectively gathered over 120 million online searches, demonstrating substantial global demand for the world’s most covetable luxury items (Digital Luxury Group, 2013) (see Figure 1) . Figure 1: demand of luxury handbag globally (Digital Luxury Group, 2013) The country subjects are UK and Indonesia. Despite the fact that both of Indonesia and UK are reflected as positive luxury market (Digital Luxury Group, 2013; Euromonitor, 2014), both of the countries have differences which may lead to different motivation of luxury purchase. Indonesia is emerging market, while UK is a mature market. The rise of emerging market makes difference. Back then, individualist country is more refer to western developed countries, while collectivistic country is refer to eastern developing countries (Hofstede, 2011; Shukla, 2012). Nowadays, emerging countries are catching up with developed countries (Nielsen, 2013). Increasing exposure to global media and the depiction of western lifestyles in local media seem to have increased the desire for high-quality goods and services among consumers in emerging markets (Belk, 1999). With regards to luxury products and services, studying the consumption patterns in emerging markets is particularly important due to the phenomenal growth of luxury consumption among consumers in these markets (Shukla, 2012). For example, according to Bain and Company (2012), 85 per cent of all luxury stores will be opening in emerging markets over the coming decade. Moreover, recent studies highlight the significantly strong influence of the materialism trait with luxury consumption in emerging markets (Lertwannawit and Mandhachitara, 2011; Podoshen et al., 2011). As predicted by BCG (2010), in 2015, emerging-market cities will account for around 20 per cent which is $2.6 trillion of the total global consumption of clothing and house as a priority of future expenditures. The key consumer base for luxury goods has long since left Europe, moving West to the United States, but also East to the Gulf States and Asia, and South to Latin America, particularly Brazil (Business of Fashion, 2014). Luxury companies are no longer focusing for mature market. However, luxury goods enable consumers to satisfy their material as well as socio-psychological needs to a greater degree than regular goods (Vigneron and Johnson, 2004; Wiedmann et al., 2009). Luxury brands are one of the most profitable and fastest-growing brand segments, yet at the same time, the social influences associated with luxury brands are poorly understood and under investigated (Shukla, 2010; Wiedmann et al., 2009; Tynan et al., 2010). Increasing exposure to global media and the depiction of western lifestyles in local media seem to have increased the desire for high-quality goods and services among consumers in emerging markets (Belk, 1999). With regards to luxury products and services, studying the consumption patterns in emerging markets is particularly important due to the phenomenal growth of luxury consumption among consumers in these markets (Shukla, 2012). From those passages, it can be inferred that emerging market countries are the targets of luxury brand companies to invest in the market. Culture is changing: The rise of Emerging Market As previously discussed in the second chapter, when the political, societal, and economic environments change, people's cultural values also change. Thus, many cultural theories should be updated and re-evaluated periodically. Hence, Wu (2006) said that Individualistic vs. Collectivistic Dimension theory is no longer applicable. Additionally Saiq et al. (2014) said that Hofstede’s Individualistic Dimension work is too old and can’t be effectively implemented in the era of rapidly changing environment, convergence and globalization. The arguments by Wu (2006) and Saiq et al. (2013) is supporting Bian and Forsythe (2012) which argue that culture is changing as a consequence of the increasingly global economy especially in emerging market, converging in the direction of greater individualism. As a result, collectivist societies might adopt some individualistic elements, but this would not change their societal identity or their social label as a collective society (Bian and Forsythe, 2012). The contrasts between few contemporary studies of luxury value perception in Individualistic vs. Collectivistic Country (Bian Forsythe; 2012, Li et al, 2012; Shukla and Purani, 2012) (see Table 1) are leading to confusion in understanding value perception on luxury purchase between individualistic country vs. collectivistic country. For an instance, according to Li et al. (2012), a collectivistic country (China) has high consideration of functional value dimension for luxury purchase, but according to Shukla and Purani (2012), a collectivistic country (India) has low consideration of functional value perception for luxury purchase. Another example, according to Bian and Forsythe (2012), an individualistic county (US) consider high personal and social value dimension for luxury purchase, but according to Shukla and Purani (2012), individualistic country (UK) consider low personal and social value dimension on the luxury purchase. The study results were supporting a statement of Shukla (2012) that culture is not static and it keeps changing Table 1: The contrast between study results about value perception across culture Impact on the Future Brand Strategy Consumer value plays as critical role at the heart of all marketing movement and hence undoubtedly deserves attention of every consumer scholars (Holbrook, 1999) especially, in the next decade, customer is predicted as the key orientation of luxury business (BCG Report, 2014) (see Figure 2). The current crisis in luxury marketing area is encouraging companies to look more deeply into the links between consumers and luxury brands (Godey et al., 2013). Consumption of luxury products is based on two main reasons: the purchase for one’s self, for pleasure and purchase as a symbol of success (Godey et al., 2013). Nevertheless, whatever the perspective chosen, the brand remains the main vehicle for connecting with the consumer (Godey et al., 2013).To understand the right brand strategy, the purpose of this study is to identify the constructs of perceived peer communication in social media activities of luxury fashion brands, and to evaluate the influence of those activities on purchase intention in the UK and Indonesia. This research will propose a strategy to enhance brands' performance by defining specific factors relating to purchase intention. Moreover, the findings will enable luxury brands to forecast customer purchasing behaviour. The full conceptual model of this study can be found on Figure 2. Figure 2: The conceptual model of the study Methodology Steenkamp and Baumgartner (1998) suggest using a structural equation modelling approach for cross-culture study. SEM analysis has been successfully applied by many scholars to measure luxury value perception (Bian & Forysthe, 2012; Shukla, 2012; Casidy, 2012; Monkhouse et al., 2013; Hennigs et al., 2013). The structural equation design of this study is illustrated on Figure 3. The method of self-completion questionnaire allows for a greater geographical coverage than face-to-face interviews without incurring the additional costs of time and travel and they are particularly useful when carrying out research with geographically dispersed populations (Seale, 2012). Self-completed questionnaires were distributed to thirty students with snowball sampling by online survey to each country (UK and Indonesia) and twenty valid samples were utilised from each country. Criterion sampling strategy reviews all cases that meet predetermined criteria (Patton, 2002). Both criterion and snowball sampling techniques were components of a purposeful sampling strategy designed to identify participants with this criteria: A. Originally from and live in Indonesia or originally from and live in the UK. B. Having experience in purchasing at least one of luxury handbag. Figure 3: The structural equation design of the study Result There are significant differences of value perception on luxury handbag between Indonesian consumers and UK consumers. Indonesian consumers are highly influenced by Social Value Perception while British consumers are less influenced by Social Value Perception when buying luxury handbags. British luxury handbag consumers are more focusing on the Functional Value Perception which is not much considered by Indonesian consumers. However, consumers from both countries are highly influenced by Personal Value Perception.

The 47th Session of the UNCITRAL finalized the draft Convention on Transparency in Treaty-based Investor-State Arbitration. It aims to provide a mechanism to allow the UNCITRAL Rules on Transparency to be applied to investment dispute arbitrations mandated by investment treaties concluded before April 1, 2014. This paper intends to examine these UNCITRAL Rules on Transparency and the draft Convention on Transparency. It is particularly in contrast with the relevant rules in the NAFTA, the U.S. Model BIT 2012 and the ICSID Rules 2006, to see if transparency can be enhanced in treaty-based investor-State arbitrations and to extrapolate the implications of the Rules on Transparency and the draft Convention for China’s strategy in BIT or FTA negotiations amid the trendy advancement of transparency standards.

Stroke is the most basic element in modern Chinese character structure unit, normalization and standardization of stroke cannot only be essential to literacy teaching, and writing, retrieval and computer processing of Chinese characters, but can further improve normalization and standardization levels of Chinese characters. However, there are lots of disputes about many issues of stroke in academia, and contents about stroke in modern Chinese teaching materials in colleges and universities are inconsistent. Ten representative teaching materials of Modern Chinese are selected in this article to take strokes in these teaching materials as study object for comparison and analysis of classification, names and sequence of strokes, so as to give suggestion to normalization and standardization of strokes. The teaching materials involved in this article include: Modern Chinese (the 4th revised edition) written by Huang Borong and Liao Xudong in 2007, referred to as “Huang and Liao‟s Version”; Modern Chinese written by Hu Yushu in 1992, referred to as “Hu‟s Version”; New Modern Chinese written by Zhang Bin in 2002, referred to as “Zhang‟s Version 1”; Modern Chinese written by Zhang Zhigong in 1982, referred to as “Zhang‟s Version 2”; Introduction to Modern Chinese written by Shao Jingmin in 2001, referred to as “Shao‟s Version”; Modern Chinese written by modern Chinese teaching and research office of Department of Chinese Language and Literature of Peking University in 2000, referred to as “Bei‟s Version”; Modern Chinese Character Outline written by Su Peicheng in 2001, referred to as “Su‟s Version”; Modern Chinese Tutorial written by Xing Fuyi① in 1986, referred to as “Xing's Version"; Modern Chinese written by Zhou Yimin in 2006, referred to as “Zhou's Version”; Modern Chinese written by Ma Guorong in 1990, referred to as “Ma's Version”.

We have examined morphological change and movements of individual sunspots within a sunspot group in association with a large solar flare activity (3B/X1.5) appeared on 13 May 1981. For this purpose we measured distance among spots during the period before and after the flare activity and estimated the average velocity of their movement. Our main results are as follows: (1) The longitudinal displacement among sunspots are generally greater than the latitudinal displacement. (2) During the period the spots moved with an average velocity of 1.2 km/s in longitude and 0.86 km/s in latitude. (3) The most notable change took place in the central part placed between the two ribbons of the flare.
