  • As online learning forms centered on video lectures become more common and constantly increasing, the video-based learning environment applying various educational methods is also changing and developing to enhance learning effectiveness. Learner's log data has emerged for measuring the effectiveness of education in the online learning environment, and various analysis methods of log data are important for learner's customized learning prescriptions. To this end, the study analyzed learner behavior data and predictions of achievement by machine learning in video-based learning environments. As a result, interactive behaviors such as video navigation and comment writing, and learner-led learning behaviors predicted achievement in common in each model. Based on the results, the study provided implications for the design of the video learning environment.

  • 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.

  • This study sought to examine how internal market orientation of service organizations affects the service providers' adaptive service behavior and to determine what psychological processes go through for this purpose. To achieve this purpose, based on previous research, a research model was set up to predict that internal market orientation of service organizations will increase service providers' adaptive service behavior by continuously mediating the psychological processes of person-environment fit and work engagement. To test the hypothesis, a survey was conducted and data were collected from nutritionists at consignment catering companies located in Busan and Gyeongnam. As a result of testing the hypotheses proposed in this study's research model, internal market orientation increased person-job fit and person-organization fit, which are key elements of person-environment fit. And, it was confirmed that person-job fit and person-organization fit have a positive effect on work engagement. Additionally, work engagement improved service providers' adaptive service behavior. Lastly, this study confirmed that the influence of internal market orientation on adaptive service behavior is continuously mediated by person-environment fit and job enthusiasm.

  • The aim of this paper is to examine the so-called theory of automatic action attributed to Plotinus, according to which the sage can act automatically without deliberation or reasoning. Concerns were raised that such a theory runs the risk of turning the agent into an automaton by reducing action to mechanical reflexes to external stimuli. I attempt to show that Plotinus does not hold a theory of automatic action by arguing that the Plotinian sage's non-deliberative action is not automatic at all. For this purpose, I first draw attention to the non-deliberative action of the World-Reason (i.e. the reason of the World-Soul), which is supposed to present an ideal model of action. Indeed, Plotinus mentions that the World-Reason rules the world "as if automatically". This is, however, meant to indicate the spontaneous and natural manner in which the World-Reason rules. In this respect, the way the World-Reason works is compared to the way nature (i.e. the productive power of the World-Soul) works. But Plotinus points out that the World-Reason knows what to do, whereas nature works without knowing. In this connection, Plotinus makes it clear that the World-Reason does not calculate or deliberate about what to do because it already knows it. To clarify this point, I turn to Plotinus' analogy of practical wisdom (phronêsis) and skill, according to which the World-Reason is compared to an accomplished craftsman or artist, who confidently works without any doubt, hesitation or difficulty, thereby expressing her intelligence, unmediated by deliberation. From this perspective, non-deliberative action according to practical wisdom turns out to be superior to deliberative action. Plotinus admits that there are difficult circumstances in which even the skilled craftsman, unlike the World-Reason who always controls the whole situation, needs to deliberate or calculate, but he is nevertheless confident that the craftsman easily finds the solution. This suggests that the sage, who possesses practical wisdom, can act normally like a great master or virtuoso without deliberation, but in an emergency situation he also employs deliberation, but resourcefully and creatively responds to challenge. The attempt is made to elucidate the Plotinian model of sage's action with the help of Csikzentmihalyi's concept of 'flow' and Annas' application of it to the analogy of virtue and skill. Finally, it is shown that the sage's virtuous action, in spite of being a habituated action, is not a passive, routinized, automatic action, but an active, flexible, intelligent action.

  • To improve the understanding and predicting power of littering behavior in natural recreation areas, a model was proposed based on the theory of reasoned action by Fishbein and Ajzen. Among the visitors of Kaeryongsan National Park in Korea, three hundred and ninety nine (399) groups were interviewed to obtain such data as beliefs about the behavioral consequences, attitudes, normative belief, socioeconomic status and etc. A significant but practically weak relationship was found between beliefs, normative belief and past behavior (R=0.3). Using Logit analysis, past behavior could be explained with relevant variables in an acceptable power ($R^2$=0.35). In the model, education, social group, occupation, age and visiting frequency were all negatively related to past behabavior. Beliefs and normative belief also behaved as expected by the theory. The study results show that the theory may be useful in predicting the undesirable behaviors in recreation areas and establishing management policy to control them. The cause of weak relationships between relevant variables were discussed and future research implications were also suggested.

  • In this paper, we present an algorithm to determine the abnormal behavior through a CCTV-based behavioral recognition and a pattern of hand using ConvexHull. In the existing way that using CCTV for crime prevention, facial recognition is mainly used. Facial recognition is the way that compares the faces that are seen on the screen and faces of criminals for determining how dangerous targets are, however, this way is hard to predict future criminal behavior. Therefore, to predict more various situations, abnormal behaviours are determined with targets' incline of arms, legs and bodys and patterns of hand movements. it can forecast crimes when an acting has been getting within common normality out, comparing whose acting patterns with the crime patterns.

  • This study attempted to investigate the effects of self-leadership on organizational citizenship behavior and turnover intention among beauty salon employees and analyze the moderating effects of job satisfaction. For this purpose, data were collected for 330 people working in beauty salons and analyzed using SPSS v. 21.0. According to multiple regression analysis, self-leadership revealed a statistically significant positive effect on the OCB and urnover intention Therefore, it was shown that self-leadership is a critical factor. To determine if self-leadership having an influence on the OCB and turnover intention is moderated by job satisfaction, variables were applied to the following models, and hierarchical regression was performed: self-leadershipto model I, job satisfaction to model II, self-leadership and job satisfaction to model III. The results found a statistically significant positive influence in all three models. Therefore, this shows that job satisfaction has a moderating effect on self-leadership, OCB and turnover intention. Self-development education as well as technical training should be strengthened to enhance self-leadership, which leads beauty salon employees' thoughts and behavior in the right direction.
