Purpose: This study aimed to identify the prevalence of alcohol and cigarette use and assess its relationship with socio-environmental, psychological, violent and behavioral factors among a sample of high school students from Lima and Callao, Peru. Methods: We utilized the data from a cross-sectional study conducted by the Yonsei Global Health Center in collaboration with the Korea International Cooperation Agency (KOICA) Peru office in November 2016. The total sample size of this study was 1,477 students. For analysis, we used bivariate and multivariate logistic regression to calculate the unadjusted and adjusted odds ratios and their respective 95% confidence intervals. Results: The current prevalence of alcohol and cigarette use among adolescents was found to be 24.2% and 12.1%, respectively. Alcohol use was affected by age, friends' alcohol use, experience of physical fighting, and involvement in other risk behaviors (smoking, drug use, and sexual intercourse). Cigarette use was affected by perceived academic performance, friends' cigarette use, and involvement in other risk behaviors (drinking, drug use, and sexual intercourse). Furthermore, students who received affection from their parents and whose parents monitored their activities were less likely to report using both alcohol and cigarettes. Conclusion: Alcohol and cigarette use among Lima and Callao adolescents is affected by socio-environmental, violent and behavioral factors. Alcohol and cigarette use prevention initiatives should promote positive parenting practices, family togetherness, and a supportive school climate. In addition, it is needed to establish peer-led programs that promote behavioral changes in students and strengthen social relations without the presence of alcohol, cigarettes, and other harmful substances.

This research examines factors affecting behavioral intention to use integrated platform (IP), which is one of the business models regarding paid digital contents, based on extended United Theory of Acceptance and Use of Technology (UTAUT2). IP is a service which is designed to make digital content charged. It combines digitalized format of newspaper, premium news or behind news, and additional information. The results of this paper show that effort expectancy, social influence and hedonic motivation have positive relationship with behavioral intention to use IP (BI). Satisfaction with newspaper shows negative relationship with BI, which means that newspaper and IP can be replaced with each other. Newspaper subscribers tend to have higher BI than non-subscribers. Performance expectancy, gender, age, and satisfaction with website do not have significant effect on BI.

The study explored the key factors(content satisfaction factor, functional satisfaction factor, inertia factor and situational factor) that influence OTT users' continued use from the perspective of Behavioral Economics. In addition to rational factors that make OTT users feel satisfied after experiencing the contents and functions by the platform, we assumed that it would also affect habitual factors from the 'status quo bias'. To verify this, an online survey was conducted on 523 adults in 20s and 40s who have subscribed to the Top3 OTT platform(Netflix, Wavve, and Tving). As a result of regression analysis, 'content satisfaction factor', 'functional satisfaction factor' and 'inertia factor' were significant in OTT continued use. 'Inertia factor' did not affect domestic OTT users. Unlike previous studies that supposed OTT service users as beings with complete rationality, this study is meaningful to explain OTT continued use by applying 'bounded rationality'.

The purpose of the study is to identify land use characteristics which have influence on residents' mental health. Land use and housing types indicators including green areas and parks were selected by analyzing the related environment and health researches. Research database for every variable from 33 neighborhoods in Jeonju city were established through National Health Insurance Corporation, where is available for getting mental and behavioral disabilities (F code) expenses. The relation between those indexes and mental health were analysed. The findings of this study are as follows : First, the higher price area like apartments and raw houses the residents lived in, the more expenditure of F-code was paid. It could be interpreted by the relatively high frequency of medical treatment and interests on the health. Second, the more green area except park were there, the more F-code expenditure was given, which could be explicated with the spatial co-relation between location of green area and apartments of Jeonju city. It was very high, and apartment element's affect on the F-code was much more than the green zone. Third, the nearer to park were the residents, the less F-code expenses was paid.

Recent technological advancements have had a substantial impact on consumer buying behavior. This research aims to determine the factors affecting consumer behavior related to the adoption of self-service technologies (SSTs). The intended findings of this study are expected to contribute to understanding consumer behavior towards the adoption of SSTs taking into account the logic of two main theories in this regard: the Technology Acceptance Model (TAM) and the assumptions of the Behavioral Perspective Model (BPM). This research follows a triangulation approach. Consequently, a number of semi structured interviews were conducted with experts and executive directors from selected SSTs providers in Jordan. In addition, the convenience sampling technique was employed focusing on current (or) previous users of SSTs in the public and private sectors in Jordan using a self-administrative questionnaire (66% response rate). The results confirmed the influence (direct and indirect) of previous experience and personal initiatives and characteristics on consumer intention to use SSTs. In addition, the results indicated the important role of the mediator variables namely: perceived ease of use (EOU), perceived risk (PR), and perceived usefulness (PU) on consumer attitude towards SSTs which in turn will positively affect consumer intention to use SSTs.

Online learning is becoming ubiquitous worldwide because of its accessibility anytime and from anywhere. However, it cannot be successfully implemented without understanding constructs that may affect its adoption. Unlike previous literature, this research extends the Unified Theory of Acceptance and Use of Technology with three well-known theories, namely compatibility, online self-efficacy, and knowledge sharing and acquisition to examine online learning adoption. A total of 264 higher education students took part in this research. Partial Least Squares-Structural Equation Modeling was used to evaluate the proposed theoretical model. The findings suggested that performance expectancy and compatibility were significant predictors of behavioral intention, whereas behavioral intention, facilitating conditions, and compatibility had a significant and direct effect on online learning's actual use. The results also showed that knowledge acquisition, knowledge sharing, and online self-efficacy were determinates of performance expectancy. Finally, online self-efficacy was a predictor of effort expectancy. The proposed model achieved a high fit and explained 47.7%, 75.1%, 76.1%, and 71.8% of the variance of effort expectancy, performance expectancy, behavioral intention, and online learning actual use, respectively. This study has many theoretical and practical implications that have been discussed for further research.

This study was purposed to apply Aizen's Theory of Planned Behavior to workers using personal protective equipment. For this purpose, occupational health nurses conducted a survey of 173 male workers who were working at 6 different factories during the period from August to October 2003. The score of each variable related to the Theory of Planned Behavior was calculated: attitude (3.74); subjective norm(4.10); and perceived behavioral control (3.48). Four preceding factors were also assessed: behavioral belief(3.63); outcome evaluation(4.05); normative belief (4.20); and motivation to comply(4.03). Analysing the results, we found that two factors of the Theory of Planned Behavior are important in this case, which were subjective norm and perceived behavioral control that were found to be in a strong positive linkage with the use of personal protective equipment. Thus enhancing subjective norm and perceived behavioral control must be the most important goal of health education for workers who must use personal protective equipment. In addition, though behavioral intention, an intermediate factor of the Theory of Planned Behavior, was not measured in this study, subsequent studies are expected to include the factor in their models.

Computer games use an intelligent method called flocking for boids' group behavioral modeling. Flocking can naturally model group behavioral patterns of unpredictable forms such as birds and fishes using some computer resource. In this paper, we implemented an ecosystem which is composed of predator and prey for group behavioral modeling of real underwater ecosystem. Also fuzzy logic is applied to implement instinct desire of ecosystem elements. As the result, we confirmed that the model can overcome breakdown of ecosystem and model naturally ecosystem behavior.

Previous studies on user training have largely focused on assessing models which describe the determinants of information technology usage or examined the effects of training on user satisfaction, productivity, performance, and so on. Scant research efforts have been made, however, to examine those effects of training by using theoretical models. This study presented a conceptual model to predict intention to use information technology and conducted an experiment to understand how training for computer skill acquisition affects primary variables of the model. The data were obtained from 32 student subjects of an experimental group and 31 students of a control group, and the information technology employed for this study was a university's electronic mail system. The study results revealed that attitude toward usage and perceived behavioral control helped to predict user intentions; outcome expectations were positively related to attitude toward usage; and self - efficacy and perceived behavioral control. The changes in those variables suggest more causal effects of user training than other survey studies.
