This study aims to know what the physicochemical properties and physical properties of the Korean traditional rice cake injulmi made from persimmon powder and glutinous rice (powder), and to come up with a standard recipe of it with the premixed powder of persimmon and glutinous rice. Cooked rice powder with 9 different levels of persimmon in cooking dough(75, 100 and 150㎛ powder with each 20, 40, and 60%) was tested for rheological parameters, the rate of swelling, degree of gelatinization, sensory evaluation, and the observation of cross section used to electronmicroscope. 1. sensory evaluation conducted by 20 university students as panelists showed that sample C received notable preference among a samples in appearance, texture and flavour. 2. The observation of cross section used to electronmicroscope revealed that mixed glutinous rice powder and persimmon powder lost their regular forms. increase in persimmon powder content increased a thin layer of starch granule, presumably due to sugar and fiber in the mixed persimmon powder granule. 3. In cooking the rice cake with 20∼60% of persimmon, it showed 6.3 to 5.5 pH. 4. Quantitative description analysis conducted by 20 university student as panelists showed that sample that sample C was preferred among 9 samples. From these results, it was concluded that glutinous rice cake cooked with 20% of persimmon powder was quite acceptable. Optimum cooking condition for the glutinous rice with persimmon powder rice cake was 30min of cooking time and 250℃ of cooking temperature with gas oven.

After establishing improved HPLC analytical method ofcefaclor in human plasma samples, a bioavailability study of cefaclor capsules was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). The standard calibration curve using an HPLC with UV detector was constructed in a range of 0.0324--16 μg/m1. The 6% perchloric acid instead of 6% trichloroacetic acid was used to precipitate plasma protein. The HPLC chromatograms were precisely and accurately resolved when spiked with human plasma spiked with cefaclor and cephalexin (internal standard). Twenty healthy male Korean volunteers received two commercial cefaclor capsules, Neocef ' capsule (Jinyang Pharm. Co., Ltd) or Ceclor" capsule {Lilly Korea. Co., Ltd.) at the 250 mg cefaclor in a 2 x 2 crossover study. There was a one-week washout period between the doses. Plasma concentrations of cefaclor were monitored for 8 hours after oral drug administration. AUC, the area under the plasma concentration-time curve from time zero to 8 hr (13 points), was calculated by the linear trapezoidal rule method. C,,,a" (maximum plasma drug concentration) and Tmax (time to reach Cma,) were compiled from the plasma concentration-time data. Analysis of variance was carried out using logarithmically transformed AUC, and Cmax. No significant sequence effect was found for all of the bioavailability parameters indicating that the cross-over design was properly performed. The 90% confidence intervals of the AUC, ratio and the Cmax ratio for Neocer/Ceclor" were 0.9049 S S < 1.0304 and 0.9776 5 S 1.226, respectively. These values were within the acceptable bioequivalence intervals of 0.80-1.25. Thus, our study demonstrated the bioequivalence of Neocef"/Ceclor" with respect to the extent of absorption.

Since Buonocore developed acid etching to enamel in 1955, resin has been widely used reluctantly in may area of dental practic. Acid etching to dentin also has developed since 1977,yet,there are many controversies on dentin bonding agents reaction to dentin comprised of high organic and water content and on its pulp response. This study is to evaluate the microscopic structural change and histologic pulp response using 3 newly developed DBAs(Clearfil photobond,Prisma Univ. Bond 2, All bond 2),after cavity preparetion on 60 human premolars scheduled for extractions. The results and the conclusion are as follows: 1.Scanning electron microscopic views on resin tag penetration,hybrid layer formation were similar among materials used. 2.Dentin bonding agents penetrated to dentinal tubules forming resin tags either in smear layer removal groups or modifying groups. 3.Hybrid layer was formed widly in all material groups. 4.Under the cut dentimal tubules,slight pulp response were noted,but the area of rihgt under the cut dentinal tubules,the pulp response were normal. 5.Pulp response of acid pretreatment to dontin was normal,but Prisma Univ. Bond 2 group showed severe vacuole formation.

Acute myocardial infarction(AMI) due to coronary embolism can occur in patients with normal coronary artery. Coronary embolism is believed to be a cause of acute myocardial infarction when emergent coronary angiography shows perfectly normal coronary trees, except for the finding of coronary artery occlusion. In this report, we describe four patients with AMI due to coronary embolism who were successfully treated using a thrombus aspiration device and anticoagulation, and those patients had intracardial thrombus arising from the left atrium due to chronic atrial fibrillation and valvular heart disease. Patients with chronic or paroxysmal atrial fibrillation can present with AMI due to coronary embolism, and thrombus aspiration with percutaneous aspiration device is a feasible treatment option for these patients along with anticoagulation the rapy.

Costume has expressed the life style and influence on natural and social environment, The purpose of this study is to understand changes of hair style and millinery life in the west. The data used in this study included in the literature on this subject. The research results can be summarized as follows. 1. A hair style of ancient times was frizz or chignon or dyed hair style. Sometimes, they wore wigs of false hair, or put on a head kerchief. Millinery has been not worn until then. 2. In the middle ages, the hat serve to symbolize the social rank or authority or religion. Turbans were worn which concealed the hair. The hair style were large stuffed rolls over which the wimple was sometimes draped. These stuffed rolls were also used to form some shapes of the hennin, principally the heart-shaped and circular cone style. The hennin was brought to France by Isabella of Bavaria in the latter part of the fourteenth century and its vogue lasted a hundred years. There were many styles of the hennin, invariably draped with a veil, floating or with wired edge. They became so extravagant in size that I found it necessary to regulate the height according to the socal position of the wearer.

This study conducted bending experiment to examine reinforcing effects after preloading of reinforced concrete by reinforcing materials and obtained the following conclusions. To sum up experimental results, it was found that CFS reinforced specimens were excellent in improving bending force and ductility capacity and CB reinforced specimen showed higher reinforcing effects. GFS reinforced specimen had lower reinforcing effects due to lower attachment than fiber reinforced material CFS. GSP reinforced specimen had larger internal force than other reinforced specimens, but it showed the lowest reinforce effects due to its low attachment to concrete and GSP reinforcing specimen showed the same or higher reinforcing effects than other reinforcing materials if its attachment to concrete is improved.

This study was to investigate the survey analysis on the environmental sanitation state within wards in a hospital by means of questionnaires and field measurement at summer and winter in 1998. The collected data were tested by ANOVA, correlative analysis and multiple regression analysis on the basis of the SPSS 7.5 package(window version). Based on the results, within wards the temperatures were 27.2℃ in summer, and 24.9℃ in winter, the moistures were 62.1% rh in summer and 26.4% rh in winter by mean. And the illuminations were 304lux in summer and 301lux in winter, the sound levels were 55.ldB in summer and 57.7dB in winter by mean. In addition, inpatients' recognition about temperatures, moistures, colors, sound levels and spaces were common in all in summer and winter. But the illuminations were somewhat higher than average in summer and winter. It is apparent that the physical, mental and sanitary environment factors have a great effect on the treatment and health care for the patients. So it is required more and more to improve and provide medical care services centering around patients. And it is necessary that the administrator be much interested in environmental quality factors to create comfortable and convenient ward environments.

도플러검사법을 이용한 새로운 심기능평가법 : 급성 심근경색증에 의한 심기능장애의 선별진단법으로서 심기능지표의 유용성 The Utility of Cardiac Performance Index in the Screening Test of Cardiac Dysfunction due to Acute Myocardial Infarction

Background : Because systolic and diastolic dysfunction frequently coexist in acute myocardial infarction (AMI), we hypothesize that a combined measure of ventricular performance using Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic chest pain. Method and Results : Seventy-one patients with AMI (47 male, 59±11 years) and 45 patients with normal coronary artery (29 male, 52±11 years) were included in the study for measurement of cardiac performance index and established parameters of ventricular function using conventional echo-Doppler methods. a new derived index of cardiac performance: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The mean value of the index was significantly different between normal and AMI(p<0.01). The degree of inter-group overlap was smaller for the index compared to other parameters. within functional groups, the value of the index did not appear to be related to heart rate, mean arterial pressure and the degree of mitral regurgitation. Conclusion : cardiac performance index is a conceptually new, simple and reproducible Doppler index of combined systolic and diastolic myocardial performance, and it is useful as screening test for patients with cardiac dysfunction due to AMI
