A 10-year-old intact female Miniature Schnauzer dog was referred with the primary complaint of persistentanorexia, remittent fever, vomiting and abdominal pain. Hemogram suggested a chronic inflammatory disease. Serumbiochemistry showed moderate hepatobiliary cellular damage with severe cholestasis. Abdominal radiography andultrasonography revealed hepatomegaly, choleliths and sludges in gall bladder and small stones in urinary bladder. Basedcholecystectomy and cystectomy, choleliths and uroliths were removed from gall bladder and urinary bladder,respectively. The clinical condition was dramatically improved after surgery.

Abstract - Removable protective adhesives for automobiles were synthesized by the emulsion polymerization of monomers, such as n-butyl acrylate(BA), n-butyl methacrylate(BMA), acrylonitrile(AN), acrylic acid(AA) and 2-hydroxyethyl methacrylate(2-HEMA), in which AA and 2-HEMA were functional monomers. Emulsion polymerization was conducted with a semi-batch type reactor. Tensile strength, extension, peel strength, viscosity and solid content of the synthesized adhesives were measured. In addition, acid resistance, alkali resistance and smoke resistance were also examined. As a result, with 0,43 mol of BA, 0,57mol of AN and 0.14~0.21 mol of BMA, the tensile strength, extension and peel strength of the synthesized adhesives satisfied the standard of removable protective adhesives for automobiles.

Residual wall thicknesses, corrosion rates, and residual life of thirty four samples of cast iron pipes(CIPs) and ductile cast iron pipes(DCIPs) collected from water mains of B city were studied to estimate their remaining service life or optimum time of rehabilitation. The internal maximum corrosion depths of samples measured using a dial gauge after shot blasting were twice higher than the external in most cases. Therefore corrosion of water pipes was much more affected by internal water quality than soil. Residual wall thicknesses of DCIPs were higher than those of CIPs. That reason was thought to be that DCIPs have been protected from internal corrosion by lining cement mortar. Residual life calculated by maximum corrosion rate was ranged up to 44 years with 12.40 years average. Since most CIPs were much deteriorated, rehabilitation plan should be established soon in B city. Residual life of DCIP was 33.52 years average. When cement mortar lining is used up by neutralization of DCIPs. DCIP also should be rehabilitated.

The sickle cell disease are a group of hemoglobin disorders characterized by red cells that undergo sickle shape transformation when they are deoxygenated. Sickle cell disease is transmit-ted as an autosomal recessive trait. This unusual property, due to the polymerization of sickle hemoglobin results in anemia and vasoocclusive complication. 1) The most clinically significant of these disease are sickle cell anemia, sickle cell hemoglobin C disease, and sickle cell beta thalassemia. Symptoms of pallor, fever, abdominal and joint pain, enlargement of the liver and spleen, swelling of hands and feet first appear near the latter part of the first year of life. Intravascular sickling affects all organs. For clinical and therapeutic purposes, exacerbations may be classified as vasoocclusive or pain, aplastic, hemolytic or sequestration crisis. we experienced a 22 year old female patient who suffered severe multiple joint pain and back pain thought to be caused by vasoocclussive phenomena.

Problems of wastes that pigs produce are increasing rapidly in the hog raising industry nowadays. consequently, the generation volume of excreta also is increasing but most of that is not disposed appropriately and exposed in eco-system therefore the disposal of stock excreta is becoming more and more serious. considering the physical and chemical characteristics of livestock excreta, the pollution loading rate - BOD, COD etc. - is very high. as alternative plan, that is, as one method kind of composisting, the utilization of the soil reformation agent will become one solution in managing the upper problems. also, the flyash of 3.7 million tons are producing every year and about 32.2% of that, 1.18 million ton is recycled as concrete, cement, cementassistance, road etc. consequently, the discharged flyash is not abandoned and a plan of recycling is needed acutely. gypsum of 4.16 million tons in 1998 presently was produced and about 57.2% of that, 2.38 million tons was recycled as cement, construction materials. the present stock is 25 million tons. therefore, in this study, because organic materials can be obtained in pig excreta and calciums can be obtained in gypsum, the small amount of elements can be acquired in flyash for the soil reformation agents, mixing the three materials - pig excreta, gypsum, flyash - adequately, investigated technique of making the soil reformation agents and described below in comparrision with the changes of temperature, PH TOC, T-N, TOC/T-N ratio etc.

We examined empirically the causes of the lead-lag relation existing in Korean stock returns, using the daily return data from 1985 to 1995. We have run the regressions of the lead-lag measures of the stock returns compared to the bench mark portfolio return on firm-sizes, trading frequencies, institutional investor's ownerships, trading volumes, and the standard deviations of returns and found the empirical evidences as followings. First, we found that the stock returns of small firms lagged the ones of the large firms. Also, the returns on less trading stocks lagged those on more trading stocks. Second, The impacts that size, frequency and volume have on the lead-lag relation of the stock returns are appeared to have the directional consistencies regardless to the analysis periods. Third, the institution's ownerships have the slightly different effects on the lead-lag relation of the stock returns according to the analysis periods. Finally, The impacts that the standard deviations of the stock returns have on the serial correlations of the stock returns have shown the considerable differences on its directions and degrees according the the analysis periods.

Generally, Educational Buildings was selected a direction, plan and scale of building according to the figure of a site. However, In the result. The selection was spent more energy and made every effort to achieve the Thermal Comfort. In the Evaluation of Energy Performance, You must consider whether it will be worthwhile. In this study, we found a difference of Energy Consumption changes according to corridor style, direction, vertical and horizontal location, and roof-space by using DOE-2.1E energy simulation program. Based on this simulation results, found a probability of reducing energy consumption in educational buildings.

This study aims to evaluate the economic performance of infiltration prevention devices for the refrigerated warehouse. It is showed that the cooling loads of refrigerated warehouses is changed by assembling of infiltration prevention devices in a previous study. Space loads and cooling energy costs according to the types of the infiltration prevention devices are analyzed by the DOE-2.1E simulation. Based on the Life Cycle Costs considered the costs of initial construction, repair·replace, cooling energy and operating energy, the probability of reducing energy consumption and application of infiltration prevent devices in vestibule of refrigerated warehouse is founded.

In evolutionary algorithm, there exist various models for the evolution of the population with respect to schemes and strategies for reproduction, in the application of the algorithm to a specific problem, one model suitable to the problem is to be properly chosen and a program expert or a software is needed to help implement and test a designed algorithm. In this study, object oriented modeling and the class library for simple evolutionary algorithms(SEA) with one population is developed. The library proposed here can be used as a generalized tool for solving problems in a wide range of domains.
