The seaside plaza at the Dodong-port of Ulleung-gun is cognized having characters of space. these characters are a gateway connecting to land, the image of Ulleung's symbol, cleanness as a whole and The scenery is beautiful beyond expression. But the seaside plaza be jammed up and be disordered with visitors, natives and mobiles, and then they didn't make the best use of the expressionist nature and landscape on the images of Ulleung of cleanness and pleasant. Therefore this study was to plan on the seaside plaza at the Dodong-port toward the heightening of Ulleung's symbol, identity, individuality through the presentation of images on cleanness and pleasant, and the expropriation of variety activities on the visitors and natives. The seaside plaza was designed with seven schemes those can be summarized as follows. The first was the adaptation of an existing variety outer functions and activities, the second was the efficient distribution of hard-pavements and green-fields, the third was the treatment of existing slopes and terraces, the fourth was the adaptation of the existing understructures and facilities, the fifth was the creation of nightscape for a night use, the sixth was for harmony of forms and functions like a meet, chat, rest, stroll and assembly, the last was the preparation for erecting a symbolic structure in the future.

Hyponatremia is the most common electrolyte disorder in hospitalized patients, and incidence of hyponatremia is about 1-4%. It is suggested that hyponatremia is closely related with morbidity and mortality in these patients. Diuretic-induced hyponatremia is one of the most common causes of hyponatremia associated with hypovolemic hypoosmolality, but serious hyponatremia due to diuretic use is relatively uncommon. Advanced age may be a predisposing cause, and women is more susceptible than men, but no definite proof has been documented. The severity of symptoms can be roughly correlated with velocity and degree of hyponatremia, and neurological symptoms generally do not occur until the serum sodium falls below 125 mEq/L. Rapid development of hypoosmolality can result in brain edema before brain adaptation occurs by excreting intracellular solutes. In the most severe cases death can result from respiratory arrest after cerebral herniation. So, it is need to optimal treatment for neurological symptoms. We report a case of serious thiazide-induced hyponatremia in elderly hypertensive man which were aggravated by infusion of simple dextrose solution without electrolyte for severe watery diarrhea.

The tetrameric STRs loci were studied in a population of Korean(n=223) for allele frequency distribution and applicability to identity and paternity testing, using multiplex PCR with electrophoresis of the PCR products in DNA sequencing gels and subsequent detection of allelic fragments by silver staining. The STRs loci analyzed were HUMCSF1PO, HUMTPOX, and HUMTHO1 ; in the Korean population, 9 alleles with their frequency range of 0.002-0.363 are detected in the HUMCSF1PO, 5 alleles with those of 0.020-1.480 in the HUMTPOX, and 6 alleles with those of 0.002-0.489 in the HUMTHO1. The highest observed heterozygosity is found at the locus HUMCSF1PO(0.709), those of the loci HUMTPOX and HUMTHO1 being 0.646 and 0.632, respectively. All loci meet Hardy-Weinberg expectations ; there are good agreement between the observed and expected values under Hardy-Weinberg equilibrium. Moreover, pairwise comparisons between loci show allelic independence for all the 3 loci comparisons. The power of discrimination (PD) determined for the locus HUMCSF1PO is 0.8896 (88.96%), that of the HUMTPOX is 0.8818(88.18%), and that for the HUMTHO1 is 0.8367(83.67%) ; the combined power of discrimination for the triplex is 0.9976(99.76%). The power of exclusion(PEX) calculated for the loci HUMCSF1PO, HUMTPOX, and HUMTHO1, being prior probability that a falsely accused father will be excluded, and 0.5173(51.73%), 0.4610(46.10%), and 0.5101(510.01%), respectively, and the cummulative power of exclusion(CPE) for all the three loci is 0.8726(87.26%). Thus, these allelic frequency data can be used to construct the database of the multiplex PCR-based DNA profile in the Korean population. The calculated parameter, "power of discrimination(PD)" and "power of exclusion(PEX)", show the informativeness of these loci for the determination of identity and relatedness of individuals.

This study consists in clarifying the meaning of various angles and velocity, and two types of the stroke of a pushing shot and hitting shot through the three-dimensional image analyses among the factors of exercise. To attain the purpose of such studies, the result of experiment and analysis for each of three athletes of boys and girls in high school and three persons in general came to the conclusion as follows; 1. The last motion of a group of A having a command of a follow shot showed greatly, compared with two groups of B and C, and this showed that a group of A took a rectilinear motion greatly to gain power and two group of B and C took a rotary motion greatly to gain speed. 2. A group of A having a command of a pushing shot move body weight forward from behind and give the first consideration to a rectilinear motion, and two groups of B and C having a command of the stroke of hitting shot used the turning of the shoulder and the waist and gave much weight to a rotary motion than a rectilinear one. 3. The position of the hitting point of a group of A having a command of a pushing shot turned out to be the waist, and that of the hitting point of two groups of B and C, the chest, and namely this showed that the position of the hitting point was decided according to the form of the stroke and pictures of various kinds. 4. In impacting, the speed decreased, for the power was controled to keep an accurate timing of stroke just before impacting

The incidence of bleeding complications may be decreasing. But, upper gastrointestinal(UGI) bleeding is a still significant complication of chronic renal failure(CRF). Although there are many controversies about clear cut guidelines for blood transfusion, blood transfusions are critically important and essential in many emergency cases. Recombinant erythropoietin has been used in the past in treatment of anemia in Jehovah's witness patients from surgery, chemotherapy, and trauma. We here report a case of the use of erythropoietin in Jehovah's witness patients with an active upper gastrointestinal bleeding and chronic anemia from end-stage renal disease. A 59-year-old male Jehovah's witness patient with a past medical history of diabetes mellitus and end-stage renal disease(receiving hemodialysis) was admitted because of hematemesis and melena. He was diagnosised with gastric ulcer on emergency gastroenteroscopy and treated with argon plasma coagulation. His hematocrit was 12.1% at admission. He refused blood transfusion and was treated with intravenous iron, ulcer medication and high dose erythropoietin. After 2 weeks, he was discharged with hematocrit 23%.

Multilocular cystic nephroma is a rare and non-inherited benign renal neoplasm occuring in the both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as simple cyst, metastatic renal tumor, cystic adenoma or angiomyolipoma in adults. We report a case of multilocular cystic nephroma presented with painful abdominal mass treated with laparoscopic nephrectomy and confirmed with pathology.

Scanning multishot irradiations on a large-area glass substrate for Xe-Arc flash lamp crystallization of amorphous silicon thin-film

<P><B>Abstract</B></P> <P>Applying an in-line Xe-arc flash lamp annealing (FLA) process for the fabrication of low-temperature polycrystalline silicon (LTPS) on a large-scale glass substrate, this study investigates the effects of scanning multishot irradiations on the thermo-mechanical deformation of the substrate and the microscopic phase-change of the amorphous silicon (a-Si) thin-film. A glass substrate with thin-film structures was preheated at 650 °C, exposed to sequential multiple flashes, and thus heated rapidly far beyond the glass softening temperature to achieve crystallization of a-Si. Temperature variations in the substrate were predicted by one-dimensional heat conduction model with radiation absorption, and the structural deformations were simulated through a FEM code and compared to the experimental observations. The maximum temperatures arisen in the substrate during the second or subsequent flash irradiations were substantially lower than that during the first irradiation owing to reduced absorptions of flash energies. These absorption reductions were resulted from phase-changes of silicon from amorphous to polycrystalline. Those temperatures, however, were still sufficiently high to cause a significant thermal warpage, resulting in the bathtub shape of the substrate. The critical mechanisms for the warpage were the structural shrinkage and the gravitational sagging. In addition, the microscopic structural characteristics of the LTPS fabricated by the scanning multishot FLA process were explored through optical and Raman spectroscopies, and transmission electron microscopy.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Scanning multishot flash lamp annealing process for large-area display. </LI> <LI> Scanning speed of 40 mm/s and flashing frequency of 2 Hz. </LI> <LI> Simulation using a viscoelastic model and experimentation using Xe arc flashes. </LI> <LI> Thermal warpage due to local softening/stress relaxation and gravitational sagging. </LI> <LI> Crystallinity estimated by transmittances, Raman spectra, TEM images. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

SiC-coated graphite was successfully fabricated at different temperatures (1300-1600 oC) through a silicon vapor depositionreaction (Si-VDR) process. Si powder was used for the Si source of the SiC coating layers. When Si powder was evaporatedat high temperature near the melting point of bulk Si, Si gases are moved and changed into Si liquid at the surface of thegraphite. The high-temperature process facilitated the formation of SiC coating layers on the graphite. The microstructural,mechanical, and thermal oxidation properties of the coated graphite were investigated.
