  • Severe sepsis and septic shock is a life-threatening disease. It is combined with multi-organ failure. In the past decade, early goal directed therapy has been proposed as an effective treatment strategy for better outcome. Recent epidemiologic studies showed that the outcome of sepsis has been improved with the introduction of early goal directed therapy. However, it is unclear which elements of early goal directed therapy contributed to the better outcome. Recent prospective and randomized trials suggested that some elements of early goal directed therapy did not have any effect on the outcome benefit. In this paper, recent articles about early goal directed therapy will be reviewed and the effectiveness of individual elements of early goal directed therapy will be discussed.

  • Obtaining the complete trajectory of the object is a very important task in computer vision applications, such as video surveillance. Previous studies to recover the trajectory between two disconnected trajectory segments, however, do not takes into account the object's motion characteristics and uncertainty of trajectory segments. In this paper, we present a novel approach to recover the trajectory between two disjoint but associated trajectory segments, called goal-directed tracking. To incorporate the object's motion characteristics and uncertainty, the goal-directed state equation is first introduced. Then the goal-directed tracking framework is constructed by integrating the equation to the object tracking and trajectory linking process pipeline. Evaluation on challenging dataset demonstrates that proposed method can accurately recover the missing trajectory between two disconnected trajectory segments as well as appropriately constrain a motion of the object to the its goal(or the target state) with uncertainty.

  • The focus of this study was to investigate whether flow occurs during both goal-directed and experiential activities, if experiential and foal-directed flow states differ in terms of various measures and dimensions. Fifty male and eighteen female subjects were participated in controlled, comparative experiment between goal-directed and experiential activities in problem-solving tasks. The findings indicate that subjects experience more curiosity and involvement(focus) in problem solving tasks with experiential activities. However, the results showed subjects experience more enjoyment in tasks with goal-directed activities. Findings of this study suggested that more sophisticated and quantitative measures in various dimensions should be constructed and verified in order to apply flow theory to human-computer interaction.

  • This study is to apply a goal-directed model for ethical consumption behavior and to see which factors influence consumers' boycott intention. We identify factors related to a goal-directed model for consumers, level of ethical consumption tendency, and boycott desire; in addition, factors that affect boycott intentions were also analyzed. The results of this study are as follows. First, consumers' boycott intentions are not high and public intention motivation is relatively low. Second, negative anticipated emotion shows an indirect effect with boycott desire as a mediator. Third, ethical consumption tendency has a significant effect on boycott desire and boycott intention. Therefore, we have to let consumers know that boycott actually shows a consumer's right and that it is also necessary to conduct various ethical consumption education.

  • Inspired by the multi-scale nature of hippocampal place cells, a biologically inspired model based on a multi-scale spatial representation for goal-directed navigation is proposed in order to achieve robotic spatial cognition and autonomous navigation. First, a map of the place cells is constructed in different scales, which is used for encoding the spatial environment. Then, the firing rate of the place cells in each layer is calculated by the Gaussian function as the input of the Q-learning process. The robot decides on its next direction for movement through several candidate actions according to the rules of action selection. After several training trials, the robot can accumulate experiential knowledge and thus learn an appropriate navigation policy to find its goal. The results in simulation show that, in contrast to the other two methods(G-Q, S-Q), the multi-scale model presented in this paper is not only in line with the multi-scale nature of place cells, but also has a faster learning potential to find the optimized path to the goal. Additionally, this method also has a good ability to complete the goal-directed navigation task in large space and in the environments with obstacles.

  • This paper proposes two contributions. One is an analysis for the limit of the subject of goal-directed reactive robot navigation, and the other is an effective navigation method employing the scheme of the subject. The analysis for the subject is presented in order to clarify the limit of the method. On the basis of the analysis, a safety-guaranteeing and deadlock-free reactive navigation method is newly proposed. The proposed method has a simple behavior-based frame such that it can make the required navigation tasks such as obstacle avoidance, deadlock resolving, and etc. with a very small set of behaviors in entirely unknown environments such as a living room, an office, and etc. Some results of experiments show these validities.

  • This study is intended to help internet marketers by trying to segment consumer who had experience in buying clothing in internet shopping-malls. Concrete purpose of this study was 1)to segment by Buying Motives of Internet Clothing Buyer, 2) to identify demographic traits of segmented groups and 3) to identify buying behavior traits, internet shopping-mall choice criteria of segmented groups. The data of 500 respondents were collected by questionnaires in internet survey site. The results were as follows : 1) 5 factors; convenience, informational, hedonic, economic, easiness of refund were revealed by factor analysis, 2) 3 group types by buying motives; information-oriented, hedonic, convenience-oriented were identified by cluster analysis, 3) 3 groups were different in demographic traits, 4) goal-directed/experience-directed behavior and shopping-mall choice criteria of three groups were different. And then marketing implications were discussed.

  • When 'rational' is understood to be 'complying with the principles of reason', we can discern two kinds of rationality---one is what may be called 'instrumentally rationality', which is involved in achieving an already fixed goal most effectively, and the other 'goal-directed' rationality, which we should have recourse to in finding out the desirable goals. The critical situations in the age of science is thought to be closely related with the fact that the 'goal-directed' rationality has been discarded as nonsensical. The goal-directed rationality was dealt a severe blow in the latter part of the last century, when the rationality of science was challenged by the scientific relativists. This paper investigates the possibility of making sense of the goal-directed rationality in the modern age of science.

  • The purpose of this study is to explore structural relationship between cognitive factors and emotional factors in predicting behavioral intention of duty-free users. This study conducted questionnaire survey on 246 users of duty-free shops and analyzed it by using structural equation. As the result of the study, attitude was significantly associated with both desire and behavioral intention. Subjective norm had a significant impact on desire, but had no significant imfact on behavioral intention. Whereas perceived behavioral control did not have a significant influence on desire and intention. Desire, which plays mediating role as a major variable in goal-directed behavioral model, turned out to not only have significant impact on behavioral intention but has the strongest effect as well. This study has its academic meaning in that it explored factors which have effect on decision-making process of duty-free users focusing on goal-oriented behavioral model, which is one of integrated psychological models. In practical terms, this study can be used as a basic material for corporations to establish goals in domestic duty-free shops.
