Ever since the Enlightenment period, judgment, information representation, and actions were believed to be rational in the sense that they are carried out according to the universal rules and principles. It has been a belief that the standard rules that support the rationality of human judgment, reasoning, and decision-making can be restored to the principles of deductive logic or to algorithmic and probabilistic law. Such classical rationality is based on the idea of autonomy of reason that a certain system of knowledge can be established from individualistic viewpoint. The idea of classical rationality ignores the social and cultural origin on a mass level. However, since the 1970s, many inconsistencies have been observed between the rational norm of inference, judgment, decision and the real judgment of human. Especially, the study of cognitive science raised questions about the rationality of human reasoning and actions, by reporting many reasoning errors that failed to follow the logical rules. In these situations, G. Gigerenzer and his colleagues suggest the bounded rationality model. It is an effort to question the very idea of traditional rationality itself, and to figure out a new paradigm or model for rationality. They first reject many kinds of dichotomy-that is, the division of what is logical and psychological, formal and content, theoretical and practical, context of discovery and context of justification, biological and cultural-which serves as the foundation for classical rationality. After the elimination of dichotomy, they pay attention to the adaptive nature that is possessed by our human recognition. According to their study, human reasoning and actions are the result of adaptive thinking. Also, the rationality in the real world is ecological, bounded, social, and heuristic. Currently, bounded rationality is the topic for interdisciplinary study that is being established by the reflection of traditional rationality. The purpose of this essay is to examine the idea of bounded rationality, and to diagnose its potentials and limitations. For this purpose, the discussion in this essay shall develop as follows. First, we will define the idea and history of bounded rationality. Second, we will investigate the organistic relational model of judgment and information representation that the inseparability of judgment and ecological structure implies in bounded rationality. Here, a recognition model will be given based on the organistic relational model. Third, we will discover the clue to solve the problem of misconception by applying the organistic relational model of judgment and information representation to scientific education. Fourth, we will discuss the role of law, rule and norm that are applied to practical problem solving in coherence to bounded rationality. Finally, we will compare the traditional arguments of scientific rationality and the idea of bounded rationality, and indicate the limitations of bounded rationality.

Bile duct web is a very rare disease. Since it has been first described in 1939 by Carter, about 40 cases have been reported worldwidely. It is frequently associated with bile duct stone, and occasionally related to bile duct trauma or primary sclerosing cholangitis. Here we report a case of common bile duct web treated with balloon dilatation.

This paper describes an approach for estimating the unsteady flowrate through a hydraulic pipe lines and a components in real time. Concerning the dynamic characteristics of a hydraulic pipe lines, experimental research from the view point of focusing on the unsteady flowrate through a pipe is insufficient because of the lack of adequate flowmeters. In this experiment, a new instantaneous flowrate measurement system making use of a sharp-edged cylindrical choke and LDV has been proposed and developed by the authors. The unsteady flowrate is obtained from the measurements center-line velocity of a circular pipe using LDV and the pressure difference using a sharp-edged cylindrical choke, and experiments on the frequency characteristics are carried out. The results show a good agreement between the estimated and directly measured flowrate waveforms illustrates the validity of the method proposed here.

저자들은 형제 자매간에서 발견된 3예의 선천성 담관확장증을 경험 하였기에 문헌 고찰과 함께 보고하는 바이다. Congenital biliary ectasia is characterized by cystic dilatation of the major intrahepatic radicles (Caroli's disease) or the inter-and intralobular ducts (congenital hepatic fibrosis) or both. Caroli's disease is characterized by communicating cavernous ectasia of the intrahepaic bile dusts. Congenital hepatic fibrosis is characterized by diffuse portal and perilobular fibrosis and multiple irrebulal buzarreshaped bile ductules in the area of fibrosis. Both result from similar malformations of the embryonic ductal plate at different levels of the biliary trees. Endoscopic retrograde cholangiography or percutaneouse transhepatic cholangiography seems to be the ideal method for diagnosis of the congenital biliary ectasia. Authors experienced 3 cases of congenital biliary ectasia in 3 siblings confirmed by endoscopic retrograde cholangiography and report the cases with the review of the literature.
