Gastrointestinal complications (GI) after thoracoabdominal aortic repair can be classified as biliary disease, heptic dysfunction, pancreatitis, GI bleeding, peptic ulcer disease, bowel ischemia, paralytic ileus, and aortoenteric fistula. Theses complications are associated with high post operative morbidity and mortality. Most of the aortoenteric fistulae after thoracoabdominal aortic surgery are found at the duodenum, near the surgical site. These rare complications are caused by an indirect communication with abdominal aorta that originated from an aneursymal formation ruptured into the duodenum. Such aorto-duodenal fistula formation is considered as a result of inflammatory change from secondary infection near the surgical instruments. Herein, we report two cases of massive upper GI bleeding from aorto-duodenal fistulae and spontaneous lower GI perforation related to cytomegalovirus infection after abdominal aortic aneurysmal repair operations.

Adefovir dipivoxil, an acyclic nucleoside analogue, has been approved for the treatment of patients with chronic hepatitis B. This agent is efficacious particularly in those who have developed lamivudine resistance. The report according to hypophosphatemia induced by low dose adefovir therapy is very rare. We report one case in which osteomalacia with hypophosphatemia developed in a patient with chronic hepatitis B on adefovir dipivoxil at a low dose, 10 mg daily. A 66-year-old man, who had been taking adefovir for more than 4 years due to lamivudine resistance, presented with muscle weakness and bone pain in both thighs. After 3 years of adefovir therapy, hypophosphatemia and elevated serum alkaline phosphatase levels had been noted. A bone scan showed multiple hot uptakes. All the image findings and clinical symptoms, such as bone pain and muscle weakness were improved after correcting the hypophosphatemia with oral phosphorous supplementation.

This study analyzed ship traffic using in IBS (Integrated Bridge System) in relation to the volume of traffic at traffic separation zone marine traffic on route to or from Yeosu-Gwangyang Port and examined the risk factors and countermeasures for marine transport safety management. As a result of marine traffic survey in Yeous-Gwangyang port for three days in October 2017, daily average passing ships were 411 ships, and about 65% of the total passing ships between 06:00 and 18:00. The volume of traffic in the traffic separation zone as an incoming and outgoing vessel were about 370 of the total vessels and accounted for about 30%. The Dangerous cargo carriers accounted for 58% of all vessels, 27% of general cargo vessels, 9% of containership and 6% of other vessels. As a result of VHF, general reports were the most common items with 65%, information provision were 19%, response ship communication were 11%, non-response and warning measures were 5%. It was found that many cargo ships and tanker vessels in the traffic separation zone encountered the most frequently when incoming and outgoing routes. Consequently, the safety traffic separation schemes are as follows; A vessel using a traffic separation schemes needs the active passing management system in the traffic separation zone, where the medium work ships incoming and outgoing in the specified areas including the costal traffic routes is urgently needed safety management for the passing routes of large ships.

We are studying some multi-functional switch, especially rotary type, for the control of several devices in car. And these switches can be applied with the several feeling patterns. detent force, detent angle, detent counts and so on. These switches are called as a haptic switch. A actuator inside the switch like electromagnetic, motor and so on is allowed to control these functions. So we need to control these actuators effectively for emotional operation of the switch. We have to understand the controlled characteristics of the switch. Here we study the these characteristics of the haptic switch with test. There are some factor to control the actuator with a program and environmental factors. We would like to find the output torque corresponding to these input factors like magnitude and width of the detent and rotational speed, voltage, ambient temperature. And it is useful to make the emotional feeling and to understand other physical phenomenon.

Background/Aims: Metabolomics is a powerful tool for measuring low-molecular-weight metabolites in an organism at a specified time under specific environmental conditions. The aim of this study was to determine the usefulness of metabolomics in identifying the metabolites in stool-fat-positive specimens, and to establish whether the results could be used to predict the long-term prognosis. Methods: Fecal specimens were collected from 52 subjects with bowel habit change. The subjects were accessed using Rome III questionnaires and Bristol stool scale form, and followed after three years. The feces samples were centrifuged and the resulting extracts reconstituted for liquid chromatography/mass spectrometry analysis. The datasets were autoscaled, log-transformed, and mean-centered in a column-wise fashion prior to principal-components analysis and partial least-squares-discrimination analysis modeling. Results: Fecal samples from 10 of the 52 patients gave a positive stool-fat result of 30-100 μm; those of the remaining 42 contained neither fatty acids nor neutral fats. The peak intensities of lithocholic acid (p=0.001), lysophosphatidyl ethanolamine (lysoPE) 16:0 (p=0.015), and lysoPE 18:1/0:0 (p=0.014) were correlated with the size of the fatty acid. Subjects with positive stool-fat result showed higher score in Bristol stool scale form than those with negative stool-fat result at initial (p=0.040) and after three years (p=0.012). Conclusions: The metabolomic assay of stool fatty acid revealed mainly lysoPEs and lithocholic acid. The size of the fatty acid was correlated with higher concentrations of lysoPEs and lithocholic acid in stool-fat-test-positive specimens and related to loose stool even after three years of follow-up period.

Compartment syndrome is rarely associated with non-traumatic rhabdomyolysis. We report the case of a 23-year-old man who developed compartment syndrome associated with rhabdomyolysis caused by prolonged immobilization after antidepressive drug overdose. Elevation of serum creatine phosphorkinase and myoglobinuria indicated rhabdomyolysis. Painful swelling of the right buttock and thigh and right lower limb paralysis with sensory and motor deficit were suggestive of gluteal and thigh compartment syndrome with the complication of sciatic nerve injury. The patient received an immediate fasciotomy, medical treatment and rehabilitation. At five months after initial treatment, the patient could walk independently with nearly full recovery of his right lower limb function.

This paper investigates the application styles in reduplication within the framework of Correspondence Theory(McCarthy & Prince, 1995a); normal application, overapplication, underapplication, and the emergence of the unmarked. In this paper, we argue that the application styles are results from the conflict of faithfulness constraints and well-formedness constraints. To explain reduplication, Generative Phonology(Chomsky & Halle, 1968) has assumed a mapping from underlying to surface forms. This idea of the grammar allows us to determine a single form from which it is possible to derive all shapes. In Correspondence Theory, which is based on Optimality Theory(McCarthy & Prince, 1993), however, the input-output mapping is determined by the interaction of faithfulness constraints and well-formedness constraints. This paper is organized as follows: In Section 1, we provide an introductory remark about this paper. In Section 2, we introduce Correspondence Theory(McCarthy & Prince, 1995a), and then argue that the application styles are results from the conflict of faithfulness constraints and well-formedness constraints. Section 3 is a concluding summary of this paper.
