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.

In this work, Ag3PO4/In2S3 nanocomposites with low loading of In2S3 (5-15 wt %) are fabricated by two step chemical precipitation approach. The microstructure, composition and improved photoelectrochemical properties of the asprepared composites are studied by X-ray diffraction pattern (XRD), field emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photocurrent density, EIS and amperometric i-t curve analysis. It is found that most of In2S3 nanoparticles are deposited on the surfaces of Ag3PO4. The as-prepared Ag3PO4/ In2S3 composite (10 wt%) is selected and investigated by SEM and TEM, which exhibits special morphology consisting of lager size substrate (Ag3PO4), particles and some nanosheets (In2S3). The introduction of In2S3 is effective at improving the charge separation and transfer efficiency of Ag3PO4/In2S3, resulting in an enhancement of photoelectric behavior. The origin of the enhanced photoelectrochemical activity of the In2S3-modified Ag3PO4 may be due to the improved charge separation, photocurrent stability and oriented electrons transport pathways in environment and energy applications.

Background: Augmented somatosensory feedback stimulates the mechanoreceptor to deliver information on bodily position, improving the postural control. The various types of such feedback include ankle-foot orthoses (AFOs) and vibration. The optimal feedback to mitigate postural sway remains unclear, as does the effect of augmented somatosensory feedback on muscle co-contraction. Objects: We compared postural sway and ankle muscle co-contraction without feedback (control) and with either of two forms of somatosensory feedback (AFOs and vibration). Methods: We recruited 15 healthy subjects and tested them under three feedback conditions (control, AFOs, vibration) with two sensory conditions (eyes open, or eyes closed and the head tilted back), in random order. Postural sway was measured using a force platform; the mean sway area of the 95% confidence ellipse (AREA) and the mean velocity of the center-of-pressure displacement (VEL) were assessed. Co-contraction of the tibialis anterior and gastrocnemius muscles was measured using electromyography and converted into a cocontraction index (CI). Results: We found significant main effects of the three feedback states on postural sway (AREA, VEL) and the CI. The two sensory conditions exerted significant main effects on postural sway (AREA and VEL). AFOs reduced postural sway to a level significantly lower than that of the control (p = 0.014, p < 0.001) or that afforded by vibration (p = 0.024, p < 0.001). In terms of CI amelioration, the AFOs condition was significantly better than the control (p = 0.004). Vibration did not significantly improve either postural sway or the CI compared to the control condition. There was no significant interaction effect between the three feedback conditions and the two sensory conditions. Conclusion: Lower-extremity devices such as AFOs enhance somatosensory perception, improving postural control and decreasing the CI during static standing.

Carbon materials with tailorable structures and superior properties have great potential applications in environmental protection, energy conversion, and catalysis. Plant biomass as abundant and green non-toxic raw materials has been considered as good precursors for synthesizing heteroatom-doped carbon materials. However, few studies have been reported on the different natures of carbon materials derived from different parts of the same plant biomass. In this study, we prepared carbon materials from the petioles and blades of apricot leaves by direct pyrolysis without additives. Detailed characterizations indicate that these two carbon materials are similar in element composition and graphitization degree, but differ greatly in surface area and pore volume. These differences can be attributed to the different contents of inorganic salts, vascular bundles, and proteins in petioles and blades. When used as catalysts for the oxidation of ethylbenzene, the petiole-derived carbon shows better catalytic performance than the blades derived carbon due to its high surface area, large average pore size, and doped nitrogen atoms. Furthermore, the carbon catalysts derived from the petioles and blades of poplar leaves and parasol tree leaves show the same difference in catalytic reaction, implying that the above-mentioned conclusion is rather universal, which can provide reference for the synthesis of carbon materials from leaves.

Energy and environmental are always two major challenges for the sustainable development of the modern human being. For avoiding the serious environmental pollution caused in the fabrication process of porous carbon, a popular energy storage material, we reported a facile, green and activating agent free route hereby directly carbonizing a special biomass, Glebionis coronaria. A nitrogen doped hierarchical porous carbon with a specific surface area of up to 1007 m2 g−1 and a N doping content of up to 2.65 at.% was facilely fabricated by employing the above route. Benefiting from the peculiarly hierarchical porous morphology, enhanced wettability and improved conductivity, the obtained material exhibits superior capacitance performance, which capacitance reaches up to 205 F g−1 under two-electrode configuration, and no capacitance loss is observed after 5000 cycles. Meanwhile, the capacitance retention of the obtained material arrives up to 95.0% even under a high current density of 20 A g−1, illuminating its excellent rate capability. The fabricated nitrogen-doped hierarchical porous carbon with larger capacitance than commercial activated carbon, excellent rate capability and cycle stability is an ideal cost-efficient substitution of commercial activated carbon for supercapacitor application.

At present, ECDIS has been widely used in ship positioning, collision avoidance and navigation, and has developed into an important part of integrated navigation and automation system. However, most ECDIS software focuses too much on system function and technical level when realizing powerful navigation AIDS, neglecting the problems that the crew are most concerned about, such as realizing the human-computer interface operation quickly and simply as well as obtaining the information of human-computer interaction effectively and accurately. In order to improve the design of Electronic Chart Display and Information system（ECDIS）human-computer interface and its usability effectively, a new method for evaluating ECDIS human-computer interface is proposed. Starting from the concept and connotation of usability, five-factor personality model is used to measure the users’ personality type in reference to the essence of usability (user’s emotional experience) and calculate the basic emotional variant of users. Then, according to the users’ emotional stimulation after finishing the given ECDIS task and combining with the system Usability scale (SUS), a tool dedicated to usability testing and five dimensions of usability evaluation proposed by Jakob Nielsen, father of usability, the emotion relationship model of usability and users is established by using partial least square method ( PLS ), and the validity of the model is verified with an aim to locate the key indicators that affect the usability of the ECDIS human-computer interface, It will be more helpful to improve the usability of ECDIS human-computer interface.

The present work introduces a new method for the recycling of waste flocculation sludge to prepare electrode materials for supercapacitor. Hazardous azo dye was removal from textile dying wastewater by a new chitosan-based flocculant, and the generated dye sludge flocs was used as a nitrogen-containing precursor for the fabrication of N-doped carbon materials. The influence of azo dye on specific surface areas, nitrogen content, pore evolution of the resulting products and their electrochemical performance were investigated in detail. The results demonstrated a dual role of azo dye worked as both a nitrogen resource and pore-forming agent. The resulting N-doped carbon nanosheets derived from azo dye flocs demonstrated high electrochemical capacitance and good stability for supercapacitor electrode, which is attributed to the unique nitrogen doping, higher specific surface area and efficient charge transfer ability.

The purpose of this paper is to compare seafarers’ behavior according to traffic conditions of a road and an onshore locations. Behaviors are classified into three categories: Skill-, Rule- and knowledge-based mode. Experimental data were collected using the questionnaires for navigators, working in a merchant ship. To compare the behaviors, we used the four analysis method; the degree of frequency, reliability test, correlation and linear regression. As a result of the study, it was found that Skill-based behavior shows more higher in the road traffic than the maritime traffic, and rule-based behavior shows more higher in the maritime traffic than the road traffic. Also, the behavior in the navigation situation showed statistical significance. Especially, in the case of Rule-based behavior, a high correlation between road and maritime was found. This study can be expected to apply to complementary system utilization between error management system of onshore and maritime traffic.

In recent years brands have come under the spotlight for delivering unique and authentic brand experiences. Consumers find themselves looking for brands that add experiential value to their daily life, from a sensory, behavioral, intellectual and relational perspective (Brakus et al., 2009). Moreover, there is a growing demand for brands that are able to deliver their brand promise authentically (Morhart et al., 2015; Schallehn et al., 2014). On this background, our research was conducted in order to examine the role of brand experience and brand authenticity in generating brand love. In addressing this issue, the present study attempts to perform a test on research hypotheses by empirically validating the proposed conceptual model in a cross-country context (Japan and Portugal) for the brands Apple and Samsung. Additionally, it analyses the moderating effect of self-authenticity in relation to brand experience and brand authenticity. Data collection was done using a structured questionnaire to final consumers, who are owners of Apple and Samsung devices. A total of 574 valid questionnaires were collected regarding Apple brand (Japan = 300; Portugal = 274). Following the testing of the structural equation model, results demonstrate the correlation between brand authenticity and brand experience and show that the greater the self-authenticity, the higher is the effect of brand authenticity on brand love. It is worth noting however that the direct and moderating effects are different for Apple and Samsung in Japan and Portugal. This accounts for the cultural differences in how consumers perceive the experiential and authentic brand value propositions and how they relate emotionally to brands. Our study also provides important managerial implications by helping brand managers to understand how to drive passionate and intense feelings towards brands and to target consumers who are looking for compelling, meaningful and authentic brand experiences.

The proportion of collision in the total marine accidents is high. The main causes of collisions are navigation rule violation, safety speed violation, neglected watch-keeping and improper collision avoidance action. There are two main ways of avoiding collision situations during maritime navigation: the method of altering course and reducing ship’s speed. The purpose of this study is to analyze the result of the collision avoidance action of the reserve officer in case of encountering a multiple number of ships using the ship handling simulator. Full-mission ship handling simulator was used to experiment the situation scenarios that encountered multiple ships. After the experiment, the questionnaire about the experiment was investigated. A total of 50 subjects were participated in the experiment. Experimental results showed that the number of the experimenters who used the engine was 11 and the number of the experimenters who did not use the engine was 39. In the case of using the engine, there were 0 collision accident, 1 grounding accident, and 10 no accidents. However, when the engine was not used, there were 28 collision accidents, 2 grounding accidents, and 9 no accidents. The causes of these results can be found in the survey results. 74 % of the non used engine participants said they were hesitate to use the engine. As can be seen from these results, the reserve officer are hesitant to use the engine and need a way to get correct of it. Maritime course subject can emphasize the importance of using ship’s engines and case study also can be it. So, It is considered that various case study scenario will need to developed by various tools in the future.

Focusing on the effectiveness of a glocalization advertising strategy in China, findings suggest that the ethnicity of endorser moderates the effect of bilingual brand naming (use of both foreign and Chinese brand names) on perceptions of a brand’s luxury quality. Introduction Given a long debate between standardization and localization, many corporations, as a solution, prefer to use both (Featherstone 1990, Sklair, 1995; Friedman, 1999). The right balance of standardization and localization is viewed as the key to success of brands being implemented at a global level, especially in countries the cultural values of which completely differ from those of the brand’s country of origin. The degree of standardization or localization in advertising is determined by various advertising elements. Advertising transfers cultural meaning through signs such as language, aesthetics, endorsers, and so forth, with brands hoping that target audiences positively associate the cultural meanings with the advertised brand (Leclerc, Schmitt & Dubé, 1994; Schmitt, Pan & Tavassoli, 1994; Cheng & Schweitzer, 1996). A brand name and the ethnicity of an endorser, out of the advertising signs, have been recognized as significant cues for conveying a brand image to consumers. This suggests that, in such a place as China, a foreign brand name or a foreign endorser in advertising produces more positive advertising-related responses for a product with foreign characteristics, compared with a Chinese brand name or a Chinese endorser (Zhang & Zhang, 2010). However, when taking a combination of the two strategies or considering the extent of localization in China, little is known about the effectiveness of a glocalization strategy in global advertising in China, which is one of the most attractive international markets to global brands, in particular, luxury brands. In reality, consistent with the argument that the combination of standardization and localization is effective, a number of luxury brands (e.g., Chanel ‘香奈儿’, Dior ‘迪奥’, Bottega Veneta ‘葆蝶家’, Estée Lauder ‘雅诗兰黛’, etc.) create their Chinese brand names when entering the Chinese market while retaining their foreign brand names. This is because most foreign brand names are either too complicated or lengthy, making it difficult for Chinese consumers to remember them or pronounce them (Zheng, 2013). Therefore, the current study attempts to examine the effectiveness of bilingual brand names as a means of a glocalization strategy. Specifically, this study investigates how languages of brand name (presentation of brand name: foreign brand name only vs. Chinese brand name only vs. both of the foreign and Chinese brand names) and the ethnicity of an endorser (Western vs. Chinese) affect consumer perception of the brand’s luxuriousness and consequently influence purchase intention. Method A 3 (language of brand name: foreign brand name only vs. Chinese brand name only vs. both foreign and Chinese brand names) x 2 (ethnicity of celebrity endorser: Western vs. Chinese) between-subject experimental study was conducted to test proposed hypotheses. Six versions of a manipulated print advertisement represented the experimental conditions. For the experiment, data were collected from a sample of 150 undergraduate students in Mainland China through a snowballing sampling technique. To increase internal validity, undergraduate students were used as the sample in the current study as it is suggested that university students are relatively a homogeneous group to reduce individual differences. In addition, considering that most of consumers for luxury goods in China are under 45 years old (Atsmon & Dixit, 2009), and the younger generation (25-35 years old) has been growing into the core consumers for luxury goods in China (Bain & Company, 2014), undergraduates are the potential consumers of luxury brands as they will, in the near future, accumulate consumption power. All subjects logged onto the study’s website, where they were randomly assigned to one of the six experimental conditions. LONGINES, a Switzerland luxury watch brand, was selected as the representative of a luxury brand for subjects, as this particular brand embraces a high degree of localization, having both English and Chinese brand names and both foreign and Chinese celebrity endorsers. It also enjoys high awareness among Chinese consumers. To manipulate the language of the brand name, three variations were used: presentation of brand name in a foreign language [LONGINES], presentation of brand name in Chinese [ 浪琴], and presentation of both brand names in a print advertisement. In the history of its advertising, LONGINES has employed 15 celebrity endorsers, 4 being Chinese. To manipulate the ethnicity of the celebrity endorser, out of the 15 endorsers, Simon Baker and Kate Winslet were selected as Western endorsers while Aaron Kwok, and Lin Chi-ling were used as Chinese endorsers. To reduce confounding effects by using a real brand, brand familiarity and brand attitude were included as covariates in the study. Findings Luxurious Perception of the Brand While controlling brand familiarity (p < .05) and brand attitude (p < .001), the language of the brand name, F(2,142) = 5.254, p < .01, had a significant main effect on the perception of a brand’s luxury quality. More specifically, a follow-up post hoc test indicated that subjects who saw the ad presenting the foreign brand name in Latin showed a stronger perception of a brand’s luxury quality than did those exposed to the ads that presented the Chinese brand name or both of the foreign and Chinese brand names. However, we found no significant difference between the presentation of the Chinese brand name and the presentation of both foreign and Chinese brand names. On the other hand, the ethnicity of the endorser was not found to have a significant effect on the perception of a brand’s luxury quality (p > .05). The results further revealed a significant interaction between the language of the brand name and the ethnicity of the endorser on the perception of a brand’s luxury quality, F(2,142) = 5.647, p < .01. Specifically, Figure 1 shows that both brand names produced a weaker perception of a brand’s luxury quality than the foreign brand name only when the Western endorser is presented, however, both brand names produced an equal effect to the foreign brand name only when the Chinese endorser is presented. The language of brand name, while controlling brand familiarity (p < .05) and brand attitude (p < .001), exhibited a significant effect on purchase intention, F(2,142) = 3.472, p < .05. A follow-up post hoc test revealed that the presentation of the foreign brand name or both of the foreign and Chinese brand names in the ad generated higher purchase intention than the presentation of the Chinese brand name. However, there was no significant difference between the conditions of the foreign brand name and the both brand names. With respect to the main effect of the ethnicity of an endorser on purchase intention, the data did not exhibit a significant effect (p > .05). No significant interaction effect between the language of brand name and the ethnicity of an endorser emerged (p > .05). Mediating Role of Luxurious Perception of the Brand To confirm the moderated mediation of the perception of a brand’s luxury quality on purchase intention, the PROCESS macro model 8 was performed. The study found significant effects of the interaction on the perception of a brand’s luxury quality: βBrand name x Endorser = .54, SE = .17, p < .01. Then, when we examined the joint effects of the interaction effect and luxurious perception of the brand on purchase intention, no significant effect was found from the interaction; βBrand name x Endorser = -.02, SE = .24, p > .05, emerged on purchase intention. However, the effect of the perception of a brand’s luxury quality was still significant; βBrand name x Endorser = .33, SE = .12, p < .01. This implies that the interaction effect of the two independent variables had an indirect effect on purchase intention through the perception of a brand’s luxury quality (CI95, 1,000 bootstrapped samples [.0492, .4229]). Specifically, the perception of a brand’s luxury quality mediated the effect of the language of brand name on purchase intention only in the condition of a Western endorser (CI95: [-.3161, -.0429]), but not in the condition of a Chinese endorser (CI95: [-.0298, .1254]). Discussion The study supports the argument that a brand name is a strong cue for consumer judgment (Thakor & Lavack, 2003; De Mooij, 2010; Elena & Segev, 2012) by suggesting that when a brand uses a foreign brand name (Roman Alphabet), consumers are more likely to view the brand as luxurious; also consumers are more likely to be willing to purchase the brand than when it uses a Chinse brand name. Interestingly, bilingual brand naming has been found to be somewhat complicated. The study suggests that using both foreign and Chinese brand names is as ineffective as using a Chinese brand name only for luxurious perception of the brand. This may be because the use of a Chinese brand name along with a foreign brand name dilutes the cultural meanings (e.g., status, social distinction, etc.) that the foreign brand name on its own transfers to consumers. With respect to purchase intention, however, the use of bilingual brand naming produces an effect equal to the use of a foreign brand name only. This finding indicates that a brand name may be more associated with the perception of brand’s luxury quality than intention to purchase the brand. This further implies that the effectiveness of a glocalization strategy of the brand name by adding a Chinese brand name to an original foreign brand name should be considered with caution. In addition, the current study extends prior research on multi-cue models of country-of-origin effects by demonstrating the moderating role of the ethnicity of an endorser in the effectiveness of the language of a brand name. When a brand uses a Western celebrity endorser, the glocalization strategy of bilingual brand naming seems to be less effective; consumers have a weaker perception of a brand’s luxury quality, compared with a foreign brand name. However, bilingual brand naming is just as effective as foreign brand naming when it uses a Chinese celebrity as the endorser. Supporting previous findings about the synergistic effect of multiple foreign cues (Huang, Fan, & Zhou, 2008), this study implies while the foreign brand name still serves as a foreign cue in bilingual brand naming, the Chinese brand name attenuates the positive effect of the foreign brand name and weakens the synergistic effect from the foreign cues of the foreign brand name and the Western endorser. On the other hand, when a Chinese celebrity endorses the brand, there may not be a synergistic effect from the multiple foreign cues of the foreign brand name and the endorser. Therefore, adding a Chinese brand name to a foreign brand name may not significantly moderate the positive effect of the foreign brand name. Finally, this paper suggests that consumer perception of a product having luxury quality seems to be a strong driver in determining the purchase of a luxury brand, especially when a western celebrity endorsers the brand. Managerially, the study provides insights into the selection of an effective brand-naming strategy and an endorser for advertising when luxury brands do business in the Chinese market. Bilingual brand naming is becoming a common practice in China. Given such a trend in China, is the glocalization strategy on brand naming being deemed effective? If viewing advertising effectiveness from the perspective of enhancing luxurious brand image, the strategy of bilingual brand naming seems to work poorly in China compared with standardized foreign brand naming. It may not be that simple, though, because multiple cues are used to infer cultural meanings of luxury brands and, furthermore, the cues would interact with one another. Considering that many luxury brands use celebrities, especially Chinese celebrities in the Chinese market, foreign or bilingual brand naming is critical to the success of luxury brands, yielding equal effectiveness in luxury perception. This implies that if a brand uses a foreign brand name only, a Western endorser would be more desirable. If the brand adopts bilingual brand naming, then utilizing a Chinese endorser would seem advisable. The study further suggests that the localized strategy in brand name–the use of a Chinese brand name only–is not a good idea for luxury brands in China.

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.

The purpose of this study is to classify the deficient abilities of seafarers into SRK (Skill, Rule, and Knowledge) and analyze and identify the SRK by the type of accident and ship. Experimental data used the SRK cumulative frequency for 1,606 marine accident records and two-way ANOVA and t-test were used for the analysis tools. The results of two-way ANOVA showed that it is possible to identify the deficient abilities by using the cumulative frequency of SRK in both accident and ship types. As a result of the t-test, the adoption of the null hypothesis (H=0) that the mean of two pairs is equal and the rejection of the null hypothesis (H=1) were 29.2 % and 70.8 %, respectively. For the ship type, H=0 is 33.3 % and H=1 is 66.7 %. Through this study, it was found that about 70 % of the deficient abilities of seafarers inherent in maritime accidents can be identified using the proposed method.

We report the use of carrot, a new and inexpensive biomaterial source, for preparing high quality carbon dots (CDs) instead of semi-conductive quantum dots for bioimaging application. The as-derived CDs possessing down and up-conversion photoluminescence features were obtained from carrot juice by commonly used hydrothermal treatment. The corresponding physiochemical and optical properties were investigated by electron microscopy, fluorescent spectrometry, and other spectroscopic methods. The surfaces of obtained CDs were highly covered with hydroxyl groups and nitrogen groups without further modification. The quantum yield of as-obtained CDs was as high as 5.16%. The cell viability of HaCaT cells against a purified CD aqueous solution was higher than 85% even at higher concentration (700 μg mL−1) after 24 h incubation. Finally, CD cultured cells exhibited distinguished blue, green, and red colors, respectively, during in vitro imaging when excited by three wavelength lasers under a confocal microscope. Offering excellent optical properties, biocompatibility, low cytotoxicity, and good cellular imaging capability, the carrot juice derived CDs are a promising candidate for biomedical applications.
