This work aimed to classify Aspergillus (8 species, 28 strains) by using a secondary metabolite profile-based chemotaxonomic classification technique. Secondary metabolites were analyzed by liquid chromatography ion-trap mass spectrometry (LC-IT-MS) and multivariate statistical analysis. Most strains were generally well separated from each section. A. lentulus was discriminated from the other seven species (A. fumigatus, A. fennelliae, A. niger, A. kawachii, A. flavus, A. oryzae, and A. sojae) with partial least-squares discriminate analysis (PLS-DA) with five discriminate metabolites, including 4,6-dihydroxymellein, fumigatin, 5,8-dihydroxy-9-octadecenoic acid, cyclopiazonic acid, and neosartorin. Among them, neosartorin was identified as an A. lentulus-specific compound that showed anticancer activity, as well as antibacterial effects on Staphylococcus epidermidis. This study showed that metabolite-based chemotaxonomic classification is an effective tool for the classification of Aspergillus spp. with species-specific activity.

In Vietnam, the airline service sector plays an important economic role. However, it is a complicated industry that is open to failures. Negative emotions are an essential variable for the airline service industry because they can trigger a variety of coping behaviors that affect consumer loyalty as well as the image and reputation of the airline service providers. However, negative emotions and the accompanying coping behaviors are often investigated partially or as separate issues, thus leading to an incomplete understanding. This study is conducted to fill this gap by proposing and testing the causal relationship between negative emotions (anger, frustration, regret) and coping behaviors (complaint, negative word-of-mouth (WOM), and switching intention) in the context of the airline industry. Eight research hypotheses are tested. Using the partial least squares structural equation modeling (PLS-SEM) on a sample of 587 passengers in Vietnam, the empirical results show that anger and frustration influence complaints, negative WOM, and switching intention, while regret leads to switching intention and negative WOM. Thus, the research has important academic and practical implications. The empirical outcome could be of major importance for airline companies in planning to provide new services and achieve high performance in the long run.

This study aims to test the interrelationship among perceived value, tourist satisfaction, quality of life, and tourist loyalty in an Indonesian tourist adventure destination. The respondents were recruited from Bromo Mountain, East-Java Province, Indonesia. For this study, 250 questionnaires were distributed, of which 240 could be used for analysis, yielding a response rate of 96%. Data was analyzed using Partial Least Squares with smartPLS 3 software. Both outer model and inner model evaluation were conducted to ensure the robustness of the proposed model. The findings showed that perceived value does not have a direct significant effect on tourist loyalty. However, tourist satisfaction and quality of life have significant effects on tourist loyalty. The mediating effect test indicated that tourist satisfaction and quality of life significantly mediated the effect of perceived value on tourist loyalty. The multi-group analysis test found that the demographic factor does not have any influence. By accomplishing its research objectives, this study provides both theoretical and practical contributions. From a theoretical standpoint, this study provides a comprehensive conceptual model in explaining Indonesia adventure tourist loyalty. From a practical standpoint, this study offers recommendations to adventure tourism management to enhance the sustainability of the tourism destination, especially the adventure tourism destination.

This study examined the relationship among constructs that impact on strategic use of IS(Information Systems). Independent variables were OIQ(Organizational Intelligence Quotient) and role of CIO(Chief of Information Officer) as a top manager, and dependent variable are strategic use of IS. The dependent variable has three-sub constructs: 1) IT infrastructure flexibility; 2) operation-orientation; and 3) market-orientation. Seven research hypotheses derived from the research model, and were empirically tested using the PLS (Partial Least Squares) method. The research results confirmed that both OIQ and CIO's roles have strong impact on organizations' strategic use of IS. Communication and business network among the sub-constructs of OIQ have effect on strategic use of IS. CIO's role as a top manager was found to be significant. CIO's role as a resource allocator and innovator among the CIO's roles showed significant influence on strategic use of IS. OIQ was also significantly related to CIO's role as a top manager. This study suggests practical implications and insights to the enterprises which aim to apply IT strategically.

A method is described for measuring clinically relevant levels of glucose in a pH 7.4 phosphate buffer by nearinfrared (NIR) absorption spectroscopy. Three types of NIR spectrometer, dispersive type, photo-diode array (PDA) type, and fourier transform (FT) type spectrometer were used and the performance was compared. Spectra were collected with a cuvette cell or quartz liquid fiber of 1 mm or 2 mm optical pathlength as transmittance method. Glucose absorption band appeared at second overtone, first overtone, and combination region for all systems. By use of the multivariate technigue of partial least squares (PLS) regression, glucose concentrations can be determined with a 16, 44, and 9.1 mg/d l standard error of prediction for dispersive type, photo-diode array type, and fourier transform type system, respectively. Sensitivity of spectrometer was evaluated by absorbance for the difference of 10 mg/d l glucose. Three absorption bands, second overtone, first overtone, and combination region were suited to three types systems, dispersive type, photo-diode array type, and fourier transform type systems, respectively. This investigation showed that three types NIR spectrometer were proper method for identification and quantitative analysis of glucose and possible for noninvasive blood glucose monitoring.

In recent years, O2O (Online to Offline) services get a lot of attention to improve the trust in online shopping and minimize the inconvenience and the cost burden in offline shopping as the number of consumers, who do not show concern about the purchase platform like online or offline, increases. Even though the services have been getting the spotlight as a strong business platform for next generation commerce, there have been only a few studies on the O2O services. The purpose of this research is to investigate the factors which affect the consumer's intention to use location-based O2O services. The study is based on VAM (Value-based Adoption Model) which is able to analyze those factors from the aspects of benefit and sacrifice. We used the partial least squares (PLS) method for empirical analysis, and the result shows that contextual offers, instant connectivity, webrooming and economic efficiency, which fall under the benefit, affect perceived value positively while annoyance and face consciousness, which fall under the sacrifice, do not affect perceived value significantly. In addition, contextual offers and instant connectivity affect trust positively. Location accuracy, which falls under the benefit of location-based O2O service, do not significantly affect perceived value and trust while security risk affects trust and use intention negatively. It appears that trust affects perceived value and use intention positively.
