Within the field of Korean linguistics, it has been observed that subjective adjectival predicate constructions are characteristic of imposing 'coreference constraint' on the higher and lower subjects, while evidential -te- constructions imposing 'non-coreference constraint' on them. I interpret these constraints as dependency constraints between higher and lower judge-sensitive semantic predicates, and investigate the interactions among subjective adjectival predicates, evidential -te-, and modal -keyss- in Korean. The paper ultimately argues for the necessity to add a new indexical element, the judge of evaluation(Lasersohn 2005, Stephenson 2007), to the traditional set of indices that were confined to the world and the time.

Amputation of diabetic foot ulcer and infection is a critical modality for saving a patient's life from life threatening infections or ischemic limbs. However, it can cause serious handicaps or complications, such as lifetime shortening and re-amputation of the other limb. The minimal amputation is the main goal of amputation in diabetic patients. However, insufficient amputation can have a harmful effect on patients. The decision of amputation is very difficult and should be made using multidisciplinary approaches. All aspects of the patient's situation, including vascular status, degree of infection, and medical conditions should be considered. The foot surgeon should keep in mind the notion that proper amputation can lead to a new life for diabetic foot patients.

The fact that colloidal particulates of rdaiogold are mainly and effectively eliminated from the blood stream by phagocytic activity of Kupffer's cells of the liver has been successfully adopted to the diagnosis if certain liver diseases and the same principle has opened a new avenue to the study of the organ by obtaining scan. Indeed, the latter procedure has been widely used for the detection of space-occupying lesions of cirrhosis of the liver. Nevertheless problem of differential diagnosis of monochromatic "cold" areas or "mottling" of the internal structure on the scan limited the value of this diagnostic modality. The present investigation is aimed at improving intepretation of photoscan findings with the aid of blood clearance rate of the intravenously injected colloidal $^{198}Au$.

PET/CT is a new imaging technology that combines high-quality Positron Emission Tomography (PET) and Computed Tomography (CT). This imaging provides simultaneous anatomical and metabolic information. Therefore PET/CT is useful diagnostic modality for early detection of malignant tumor, accurate staging, decision on therapeutic plan, monitoring response to therapy and rapid detection of recurrence. We report oral and maxillofacial cancers diagnosed by using PET/CT and the usefulness of PET/CT in the evaluation of postoperative recurrence.

Recent development of magnetic resonance imaging (MRI) equipment enables interventional radiology (IVR) as diagnosis and treatment under MRI usage. In this paper, a new methodology for magnetic resonance (MR) scanner to apply not only diagnostic equipment but for treatment one is discussed. The temperature measuring procedure under MR is to measure phase shift of $T_1$, which is the longitudinal relaxation time of proton, for the position inside a sample material with the application of pulsed RF for heating inside the sample as artificial dielectrics. The result shows the possibility to apply MR as temperature measuring equipment and as a heating equipment for applying such as hyperthermia heating modality.

This study presents an approach to synthesize multispectral images at a higher resolution by exploiting a high-resolution image acquired in panchromatic modality. The synthesized images should be similar to the multispectral images that would have been observed by the corresponding sensor at the same high resolution. The proposed scheme is designed to reconstruct the multispectral images at the higher resolution with as less color distortion as possible. It uses a regression model of the second order to fit panchromatic data to multispectral observations. Based on the regression model, the multispectral images at the higher spatial resolution of the panchromatic image are optimized by a quadratic programming. In this study, the new method was applied to the IKONOS 1m panchromatic and 4m multispectral data, and the results were compared with them of several current approaches. Experimental results demonstrate that the proposed scheme can achieve significant improvement over other methods.

This study presents a pansharpening method, so called FitPAN, to synthesize multispectral images at a higher resolution by exploiting a high-resolution image acquired in panchromatic modality. FitPAN is a modified version of the quadratic programming approach proposed in (Lee, 2008), which is designed to generate synthesized multispectral images similar to the multispectral images that would have been observed by the corresponding sensor at the same high resolution. The proposed scheme aims at reconstructing the multispectral images at the higher resolution with as less spectral distortion as possible. This study also proposes a sharpening process to eliminate some distortions appeared in the fused image of the higher resolution. It employs the Point-Jacobian MAP iteration utilizing the contextual information of the original panchromatic image. In this study, the new method was applied to the IKONOS 1m panchromatic and 4m multispectral data, and the results were compared with them of several current approaches. Experimental results demonstrate that the proposed scheme can achieve significant improvement in both spectral and block distortion.

The photodynamic therapy (PDT) is a new treatment modality of destroying malignant tumors and pre-malignant lesions based on the use of photodynamical damage to tumor cells under the photochemical reactions. But the clinical reports of photodynamic application on the benign tumor of the internal organs were extremely rare. So we decribed our experience of one case of benign tracheal tumor successfully treated by PDT.

Helicobacter pylori is one of the most commonly encountered human pathogens. It has been shown to be closely associated with peptic ulcer disease (PUD), gastric adenocarcinoma, and the gastric mucosa-associated lymphoid tissue (MALT) that may lead to gastric lymphoma. The current diagnostic methods include histology, microbiological culture, classic serology unease activity detection, polymerase chain reaction (PCR) and stool antigen detection. Its treatment modality options are multiple; however, a triple regimen consisting of a proton pump inhibitor (PPI), and two antibiotics for 10 to 14 days is preferred. Drug resistance is a growing problem in this organism and new therapeutic options are currently limited .

Impedance tomography (EIT) is a relatively new imaging modality in which the internal impedivity distribution is reconstructed based on the known sets of injected currents through the electrodes and induced voltages on the surface of the object. We describe a dynamic EIT imaging technique for the case where the resistivity distribution inside the object changes rapidly within the time taken to acquire a full set of independent measurement data, In doing so, the inverse problem is treated as the nonlinear state estimation problem and the unknown state (resistivity) is estimated with the aid of extended Kalman filter in a minimum mean square error sense. In particular, additional electrodes are attached to the known internal structure of the object ...
