This research was conducted with the aim to reveal the influence of online travel communities on tourism destinations choice, with the focus on the Russian tourism market. The preliminary results indicated that social media has significant influence on consumer behaviour and decision-making process of Russian travellers. Still, there is additional activity of Russian tourist market actors is needed to more fully use the opportunities of online travel communities.

Introduction The article presents a technique for studying the perception of images of animated characters based on the application of psychophysiological methods of recording data in combination with classical sociological methods. The theoretical justification of the EEG, GSR, PPG and video-oculography methods application in testing affective stimuli is provided. The applications of the technique at various stages of creating animated characters are presented. The main advantages of the technique are noted: the ability to work with a target audience starting from the age of 3 years old and the recording of physiological data directly while viewing a stimulus material. One of the most topical objectives for the authors of animation films is the creation of animated characters, which elicits viewers’ sympathy, influences general perception of the movie and affects its distribution and final box office. The methodology that allows to study a perception of characters at different stages of its creation, from conception to final embodiment, will help authors to make changes and adjustments before moving to another technological stage, which will reduce production costs and more accurately meet the needs of the audience. The advantage of the proposed methodology on the one hand, is the efficiency of working with child audience, which is the most difficult in terms of obtaining valid information. On the other hand, it is the possibility of obtaining data directly during the perception of stimuli, which is impossible while using sociological methods. Theoretical development The EEG method is an integral component of classical neuromarketing studies of perception of audiovisual materials, allowing assessing the attractiveness and motivational component in the choice situation. A significant number of scientific publications demonstrate the correlation between the arousal of positive emotions and the activation of the left hemisphere. This is determined by the lower power of the alpha rhythm in the left frontal lobe as compared to the right one. While a person experiences negative emotion, the right frontal lobe is more active, thus, the alpha rhythm power is lower there (Rusalov, 1988, 1999; Aftanas, 2000; Vecchiato, et al. 2011; Ravaja, 2013, Harmon-Jones, et al. 2009). In our methodology the stimuli attractiveness index is calculated based on the EEG data. The high index scores are associated with positive emotions and the interest to object; low scores are associated with negative feelings and indifference. Changes in the indicators of the vegetative nervous system activity are strongly connected to an emotional manifestation; these changes are caused by anatomical and physiological conditions. Numerous studies have demonstrated that a decrease in the amplitude of the plethysmogram is observed when a person experiences negative emotions. On the contrary, an increase in the amplitude is observed during positive emotions experience (Sylvia, et al, 2008; Kreibig, et al., 2007). The emotional involvement indicator refers to the power of emotional inclusion when viewing a character. It is calculated by the registration of vegetative indices related to emotions (EDA, plethysmogram, breathing). Interest is a cognitive need to learn about what is happening on the screen; it reflects the direct interest in visual information. The understanding of interest is mostly based on the psychological researches (Izard, 1999; Silvia, 2006), however, the intensity of the parameter can correlate with objective physiological indicators based on oculomotor activity. The process of the characters’ image scanning is accompanied by the distribution of attention to individual areas of interest (Jenkin, 2001). In this methodology we allocated the areas of interest according to a different character or a separate element of the visual image of the hero. Research design The method is based on a complex approach combining neurophysiological methods of recording physiological reactions while the demonstration of animated characters’ images in combination with sociological research methods used after the stimuli demonstration. The developed technique allows the use of any audiovisual materials created at different stages of work on a character as stimuli (design of character, design of character accessories, character model in static in 2D or 3D, technological test from 10 to 30 seconds). The data was recorded via the high-speed remote binocular eye-tracking system RED250, the professional computer polygraph (PCP) “Energia” and the electroencephalograph B-AlertX24. Result and conclusion 20 images of animated movie characters were tested on 150 respondents during the research (a child audience of animated films and an adult audience with children aged 3-8 years, who make the decision to choose an animated film). A restriction for the EEG method has been found in working with children under 7 years old. At this age the analyzed rhythms are slowed down and not completely formed. The analysis of this group of respondents was focused on vegetative indices. The predicting method of perception of animated characters’ images allows us to define the evaluation parameters of the image of the animated character in terms of attractiveness, emotional involvement and interest. The methodology will be further developed and will include a differential analysis of emotional reactions by virtue of the electroencephalography method in response to the presentation of characters or video samples. The commercial use of the technique is planned for the purpose of testing characters at all stages of animation film production.

Consumers are increasingly using social networking sites to get information about their interests. Among them, Instagram has recently reached 800 million active users (Instagram, 2017) and has a higher rate of engagement compared to Facebook or Twitter (Locowise, 2017). Despite its growing relevance, the academic research related to Instagram is still scarce. To go a step further in this topic, this research aims to examine the role played by creativity and positive emotions in driving users’ behaviour on Instagram. On the basis of the Stimulus-Organism-Response (S-O-R) framework (Donovan and Rossiter, 1982; Mehrabian and Rusell, 1974), we propose that perceived creativity (stimulus) applied to the uploaded photos or videos on Instagram results in developing positive emotions (organism) [H1]. In the same way, the use of creative posts can also affect human responses on that account, as affective commitment [H2] and interaction intention [H3]. Additionally, as a consequence of processing the information posted on Instagram account, positive feelings may arouse, resulting in greater affective commitment [H4] and interaction intention [H5]. Finally, users who experience an affective commitment with an account may tend to be more involved by interacting in the account [H6]. Data to test these hypotheses was collected from an Instagram account focused on fashion due to the relevant role that creativity has in this industry and the increasing use of this social networking site among fashion companies (Casaló et al., 2017). We obtained a sample of 808 participants which answered a questionnaire including several multiple-items measurements scales adapted from previous literature. We used a seven-point Likert-type as the response format, from 1 (“strongly disagree”) to 7 (“strongly agree”). Data analyses were carried out using SmartPLS 2.0 (Ringle et al., 2005). First, we analysed data to check validity of measures so as to confirm the factor structure, ensuring internal consistency and both convergent and discriminant validity. Results of the proposed model revealed the positive influence of perceived creativity on positive emotions (H1: β=.24, p<.01), affective commitment (H2: β=.40, p<.01) and interaction intentions (H3: β=.60, p<.01). In addition, positive emotions affect both affective commitment (H4: β=.15, p<.01) and interaction intentions (H5: β=.18, p<.01). Finally, affective commitment is also positively related to interaction intentions (H6: β=.25, p<.01). This study confirms the key role that both perceived creativity and positive emotions have on users’ responses in the Instagram context. These findings have interesting implications for management of Instagram accounts suggesting the development of creative content as well as generating positive emotions to engage followers to a greater extent in the account.

This study was carried out to estimate the effect of selected inoculants on chemical compositions and fermentation characteristics of rye silage. Rye was harvested at dough stage and divided into 5 treatments, following: No additives (CON); L. plantarum R48-27 (LP27); L. buchneri R4-26 (LB26); Mixture of LP27 and LB26 at 1:1 ratio (MIX); and L. buchneri (LB). The rye forage was ensiled into 10 L bucket silo for 100 days. The contents of NDF and ADF were lowest (P<0.05) in LB26. The pH in LB26, MIX, and LB were lower (P<0.05) than CON and LP27. Lactate content in LB was higher (P<0.05) than the others, while acetate content in LB26 and LB were higher (P<0.05) than that in CON and LP27. Lactate to acetate ratio was highest (P<0.05) in LB, but lowest in LB26. Lactic acid bacteria (LAB) count in LB was higher (P<0.05) than that in CON, while yeast count in CON was lower than in all silages applied inoculants. In conclusion, silages inoculated with LB26 could improve potentially the aerobic stability caused by increases of acetate and propionate concentrations.

We report facile solution processing of mesoporous hematite (α-Fe2O3) thin films for high efficiency solar-driven water splitting. Fe2O3 thin films were prepared on fluorine doped tin oxide(FTO) conducting substrates by spin coating of a precursor solution followed by annealing at 550 oC for 30 min. in air ambient. Specifically, the precursor solution was prepared by dissolving non-toxic FeCl3 as an Fe source in highly versatile dimethyl sulfoxide(DMSO) as a solvent. The as-deposited and annealed thin films were characterized for their morphological, structural and optical properties using field-emission scanning electron microscopy(FE-SEM), X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS) and UV-Vis absorption spectroscopy. The photoelectrochemical performance of the precursor (α-FeOOH) and annealed (α-Fe2O3) films were characterized and it was found that the α-Fe2O3 film exhibited an increased photocurrent density of ~0.78 mA/cm2 at 1.23 V vs. RHE, which is about 3.4 times higher than that of the α-FeOOH films (0.23 mA/cm2 at 1.23 V vs. RHE). The improved performance can be attributed to the improved crystallinity and porosity of α-Fe2O3 thin films after annealing treatment at higher temperatures. Detailed electrical characterization was further carried out to elucidate the enhanced PEC performance of α-Fe2O3 thin films.

The Korea Astronomy and Space Science Institute plans to develop a coronagraph in collaboration with National Aeronautics and Space Administration (NASA) and to install it on the International Space Station (ISS). The coronagraph is an externally occulted one-stage coronagraph with a field of view from 3 to 15 solar radii. The observation wavelength is approximately 400~nm, where strong Fraunhofer absorption lines from the photosphere experience thermal broadening and Doppler shift through scattering by coronal electrons. Photometric filter observations around this band enable the estimation of 2D electron temperature and electron velocity distribution in the corona. Together with a high time cadence ($<$12~min) of corona images used to determine the geometric and kinematic parameters of coronal mass ejections, the coronagraph will yield the spatial distribution of electron density by measuring the polarized brightness. For the purpose of technical demonstration, we intend to observe the total solar eclipse in August 2017 with the filter system and to perform a stratospheric balloon experiment in 2019 with the engineering model of the coronagraph. The coronagraph is planned to be installed on the ISS in 2021 for addressing a number of questions (e.g., coronal heating and solar wind acceleration) that are both fundamental and practically important in the physics of the solar corona and of the heliosphere.

Four chemical treatments with hydrogen peroxide (H2O2), copper sulfate (CuSO4), potassium permanganate (KMnO4) and chlorine (Cl2) were applied to the effluent pond water of a hybrid striped bass saltwater recirculating aquaculture system to compare their oxidation power. Four chemicals were applied at concentrations of 0 (control), 1, 5, 10 and 20 mg/l. An additional concentration of 40 mg/l was included in the chlorine treatment. Water samples from four hybrid striped bass ponds were tested with KMnO4 and Cl2. H2O2 did not reduce any of BOD, COD and chlorophyll-a, and copper sulfate was only effective on chlorophyll-a for the effluent pond. Removal efficiencies for chlorophyll-a by copper sulfate were 19.2%, 37.5%, 54.2% and 74.1% dose-dependently. Potassium permanganate effectively removed the BOD, COD and chlorophyll-a. The COD removal rates in four fish ponds varied from 15.9% to 31.6% at the concentration of 10 mg/l. Interestingly, Cl2 did not reduce the BOD and COD at all, but the BOD and COD instead increased drastically with increasing the Cl2 concentration. The pond water with the highest initial BOD and COD values among the fish ponds tested increased by 350% in the BOD and 150% in the COD at 20 mg/l. Furthermore, Cl2 did not significantly reduce any types of solid matter in this study, while KMnO4 seemed to reduce some extent volatile dissolved solid in the fish pond.

Research on the useful mushroom was done at Aurora Memorial National Park (AMNP). The Park is situated in Central Luzon Region with a total land area of 5,676 hectares. AMNP has no distinct wet and dry season thus provides a favorable climate, which promotes the growth of useful mushrooms. The photo-documentation and collections were performed to assess diversity. Five Transect Lines (TL) were laid out in five areas, with 20m x 30m quadrat and interval of 100 meters between quadrats. The study resulted in the identification of 36 families, 53 genera, and 104 species of which 97 are basidiomycetes and 6 are ascomycetes. Simpson’s and Shannon diversity indexes resulted in 0.7254 and 1.4295, respectively. In both indexes, useful mushrooms at AMNP showed moderately diverse. While the evenness revealed 0.1565 indicating low species evenness in each TL. Among the significant findings revealed two new possible new species of Microporus and Cymatoderma.

This study was conducted to estimate the effect of home or hetero fermentative lactic acid bacteria(LAB) on chemical composition, fermentation quality, and aerobic stability of rye silage. Rye forage was harvested at dough stage(28.9% of dry matter), chopped to 3-5 cm length, and divided into 4 piles for different inoculations as treatment, following 1) No additives(CON); 2) Lactobacillus plantarum at rate of 1.5 x 105 cfu/g of fresh forage(LP); 3) L. buchneri at rate of 1.2 x 105 cfu/g of fresh forage(LB); and 4) Mixture of LP and LB at 1:1 ratio(MIX). Rye silage was ensiled into 20 L bucket silo in quadruplicate for 0, 1, 4, 7, and 100 day periods. After 100 days of ensiling, the silage treated with LB had lower acid detergent fiber content(p<0.05), but higher in vitro dry matter digestibility(p<0.05). The LB and MIX reduced (p<0.05) pH more rapidly than CON and LP across the ensiling days, but had no difference on 100 days. Silage treated LP had lowest(p<0.05) acetic acid, but highest(p<0.05) propionic acid. In contrast, LB treated silage had highest(p<0.05) acetic acid, but lowest(p<0.05) propionic acid with the absence of butyric acid. On microbial count, LP treated silage had lowest(p<0.05) LAB, yeast, and aerobic stability, whereas LB and MIX treated silages had highest(p<0.05). Mold was not detected across all silages. Therefore, it could be concluded that heterofermentative LAB solely or combo with homofermentative LAB might improve in vitro dry matter digestibility, fermentation characteristics, and aerobic stability of rye silage harvested at dough stage.
