We report a case of spleen abscess cased by foreign body (gossypiboma) after 40 years. After physical examination, laboratory, ultrasonography and CT findings with diagnosis of acute abdomen, 73 years old woman had undergone laparatomy. Operation revealed intraabdominal spleen abscess. Capsulotomy and drainage of the collection was performed before splenectomy. Histological examination showed f...

In this paper we prove a lower bound of Ω(n log n) for the common element problem on two sets of size n each. Two interesting consequences of this lower bound are also discussed. In particular, we show that linear space neural network models that admit unbalanced rules cannot draw all inferences in time independent of the knowledge base size. We also show that the join operation in data base ap...

Mutual guarantee systems (MGS) of small and medium enterprises (SMEs) are complex system mainly serving the SMEs, including the mutual guarantee institutions formed by SMEs, financial institutions, industry associations and credit re-guarantee institutions. From the perspective of system theory, this paper illuminates the self-organization mechanisms and the self-organization characteristics of...

In this paper, I will argue that individual preferences toward religion have a significant relationship with an individual’s level of support for welfare spending. Specifically, this research finds that as religiosity increases support for welfare spending decreases. This assessment is reached through Ordinary Least Squares (OLS) regressions using the World Values Survey (WVS). Furthermore it l...

Does the human visual system contain a specialized system for face recognition, not used for the recognition of other objects? This question was addressed using the "face inversion effect" which refers to the loss of our normal proficiency at face perception when faces are inverted. We found that a prosopagnosic subject paradoxically performed better at matching inverted faces than upright face...

In this work, our primary focus is to determine the intersections that exist between the family of QL-implications and the families of (S, N)and R-implications. Toward this end, firstly, we investigate the conditions under which a QL-operation becomes a fuzzy implication. Since the exchange principle and the ordering property of fuzzy implications play an important role in this study, we propos...

Visual stabilization of the retina during rotational head movements requires that in far vision the eyes rotate about the same axis as the head but in opposite direction with a gain close to unity (optimal strategy). To achieve this goal the vestibulo-oculomotor system must be able to independently control all three rotational degrees of freedom of the eye. Studies of the human rotational vesti...

In paper-based workflow systems, signatures by individual or groups of people have been used extensively for various purposes. Currently there are many studies on computerizing workflow systems. Also there are studies on implementing signatures in electronic media. But the diversified purposes of a signature in workflow makes a straightforward implementation of digital signature schemes inadequ...

These last years have pointed out a significant increase of the power that needs to be transported by underground power cables. As a consequence, large cross section conductors, up to 2500mm2 are now customarily used. The CIGRE group B1-03 has completed in 2005 a work that analyses the actual AC resistance of these large cross section conductors as a function of their design. The authors discus...

introduction & objective: adequate and proper hydration during surgery is one of the duties of anesthesiologist. based on the different effects of dextrose–containing fluids and dextrose-free fluids on the level of blood sugar, we decided to evaluate the effects of these fluids on the blood sugar level after short-term surgeries. materials & methods: one hundred patients who were scheduled for ...
