콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.

Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

A marine structural material was well known to have high tensile strength, good weldability and proper corrosion resistance . Cu-containing high strength low alloy (HSLA) steel was recently developed for their purposes mentioned above, And the steel is free about preheating for welding, therefore it is reported that shipbuilding cost by using it can be saved more or less. However the marine structural materials like Cu-containing HSLA steel are being generally adopted with cathodic protection method in severe corrosive environment like natural sea water but the high strength steel may give rise to Hydrogen Embrittlement due to over protection at high cathodic current density for cathodic protection. In this study, Cu-containing HSLA steel using well for marine atructure was investigated about the susceptibility of Hydrogen Embrittlement as functions of tensile strength, strain ratio, fracture time, and fracture mode, etc. and an optimum cathodic protection potential by slow strain rate test(SSRT) method as well as corrosion properties in natural sea water. And its corrosion resistance was superior to SS400 steel , but Hydrogen Embrittlement susceptibility of Cu-containing HSLA steel was hider than that of SS400 steel. However Hydrogen Embrittlement of its steel by SSRT method was showed with pheonomena such as decreasing of fracture time. strain ratio and fracture mode of QC (quasi-cleavage) Eventually it is suggested that an optimum cathodic protection potential not presenting Hydrogen Embrittlement of Cu-containing of HSLA steel by SSRT method was from-770mV(SCE) to - 900mV(SCE) under natural sea water.

With the steady enforcement of the Five-Year Plans for Economic Development, the Korean Economy has grown rapidly in volume and structure. However, the rate of increase of the Wholesale Price Index(WPI) or the Consumer Price Index(CPI) has proved to the high caused by core, demand-pull and cost-push inflation. The primary purpose of this study is to develop stabilization measures by industry, based on methods of price compilation. First, in the mining and manufacturing sector, market structure was constituted to the pattern of monopoly and oligopoly and the market power was concentrated in the process of high growth and in A study of the wholesale price changes over 1973―1975, price changes was higher in the concentrated industries than in the competitive or less concentrated industries. Thus in the mining and manufacturing industry, effective anti-inflation policy is to control administered-prices and build up workable-competition. Second, as the stable countermeasures of the price of agricultural products. We must rearrange circulation channels, widen domestic production base and apply saving for emergency system moderately. Third, in order to induce the appropriate level of rise in service goods, government must improve productivity of the public enterprise and regulate estate prices, especially, apartment price and rent. Finally, to concrete recent price stability basis, inflation expectation mentality should be abolished and a great austerity in the living is required.

In this study, the behavior analysis of the soft ground is carried out by CRISP 4.02, finite element program using Modified Cam-Clay Model. The used values of the initial parameters were assumed rationally to represent the initial conditions of the ground. In order to analyze the behavior aspect of the soft ground, theory formula, field measure data, and finite element analysis were respectively compared. The result of the present finite element analysis were overestimated in comparison with field measure data. However, field measure data was overestimated in comparison with FEM concerning excess pore water pressure because of the efficiency degree of drain materials and decrease of permeability in the process of consolidation. Both the results of FEM and estimated values by hyperbolic mode1 were overestimated in comparison with field measure, data concerning settlement after three step embankment, but the results of FEM in comparison with estimated values by hyperbolic model were closer field measure data. Therefore, FEM under the careful laboratory tests is recommended as a future research concerning behavior aspect soft ground.

Bioequivalence of two flouxetine capsule, ProzacR (Lilly kora Ltd.) and LanclicR (Samsung Pharm. IND. Co.), was evalated according to the guideline of KFDA. Twenty four healthy male volunteers (21-26 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After 60mg of fluoxetine was orally administered, blood was taken at 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 32, 48 and 72 hours after administration and just before administration. Plasma was analyzed for fluoxetine and internal standard (clomipramine) by a sensitive and validated HPLC assay. The pharmaco kinetic parameters (AUCt, Cmax and Tmax) wre calculated and ANOVA test was used for the statistical analysis of parameters. Differences in (AUCt, Cmax and Tmax between two capsules were -0.90, 3.46 and -14.08% respectively. All powers (1-β) for AUGt, Cmax and Tmax were more than 0.9. Detectable differences (Δ) and confidence interval were all less than ±20%. All the parameters above met the criteria of KFDA for bioequivalence and indicated that LanclicR capsules are bioequivalent to ProzacR capsules.
