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.

Succinylcholine is a depolarizing neuromuscular blocking agent(NMB) and is used in induction of anesthesia. Succinylcholine-assisted endotracheal intubation has been routinely used in the operating room and rapid sequence intubation with NMB agent has been the method for airway management in emergency department(ED). Adverse effects of succinylcholine are hyperkalemia, malignant hyperthermia, transient hypotension, arrhythmia, and increased intracranial, intraocular and gastric pressure, etc. This study carried out the change of serum potassium as an adverse effects of succinylcholine during endotracheal intubation in ED. A prospective, noncontrolled design was used to study serial serum potassium levels in pre-and postendotracheal intubation(5min) from February 1996 to August 1996. Succinycholine was selectively used in patient with a ploblem of difficult endotracheal intubation (alert to drowsy mental status with intact gag reflex). The dose of succinylcholine was 1.5 mg/kg and injected into intravenous line during preoxygenation with bag-valve-mask device. Student's two-tailed t-test was used and p-value was<0.05. Among the total of 48 patients(male 27, female 21), the postintubation level of the serum potassium of 25 patients were increased and those of 21 persons were decreased compared with preintubation level. Two patient showed no change in amount. The average serum potassium indicated 3.7±0.8 mEq/L before the injection of the succinylcholine and 3.8±0.9 mEq/L 5 minutes after its injection. P-value showed more than 0.05 and as the result statistically there was no noteworthy difference. All patients were intubated within 30 sec and no patients were failed. We concluded that succinylcholine-assisted endotracheal intubation is a rapid and safe method as an endotracheal intubation practiced in ED and succinylcholin-induced hyperkalemia is miniimal and no adverse effect.

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 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.

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

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.
