We as a civil investment enterprise have been constructing In-cheon International Airport Railway which is a transportation means to approach In-cheon International Airport. In this alignment, a section between the Seoul station and Ka-joa follows the existing Yong-san line at the center of Seoul city and traverses Seoul subway 2,5,6 lines. So we planned that the alignment would have the shallowest depth to lie under Kyung-eui line and above the airport railroad. The alignment is planned to construct an open-box structure only 3.6m apart from the subway line 5 tunnel structure and construct the open-box structure 0.7m apart from the subway line 2 box structure. In the line planning, we investigated both the security of the existing subway structures during and after construction and the stability and workability between newly structured tunnel structures with three dimensions numerical analysis methods. Also we raised the reliability of design verification which was achieved by specialty society"s review on the planned construction method.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

CFWE was found to exhibit a ingibitory activity on the compound 48/80-induced anaphylaxis. CFWE inhibited the serum histamine release induced in anaphylaxis by compound 48/80. CFWE was also showed a dose-depent activity on the conpound 40/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. This result suggest that CFWE may be useful for the prevention and treatment of allergy related disease.

韓ㆍ日語의 音聲ㆍ音韻學的比較硏究 : 日本語 音聲敎育을 中心으로

辛容泰 新羅大學校 1979 論文集 Vol.7 No.-

The writer compared the pronuciation of Japanes with that Korean, and found the following problems. 1. The pronunciation of Japanese phonemes which do not exist as distinctive sounds in Korean isdifficult to master for the Korean Students. In Korean, there are three variants of velar stop consonant(??). while there are only /K/and /g/in Japanese. Difficulty in pronunciation arises when voiced/g/comes as initial position. 2. Peculiar Japanese syllables/N/,/Q, and /R/are I mora sounds, and Korean students do not give thelong vowel its correct value. 3. Asthere are many cases where vowelsounds are omitted in Japanese when the vowel/it/or/u/ comes between voiceless consonants, there is a tendency to devoice vowels, Though the vowel sound in the Koreanword 칙칙[??] is devoice there are not many instances, So Korean students have difficlty in devoicing the Japanese vowels. 4. Japanese accent is pition-accent. In Korean there is no accent except in the Kyungsang-do dialect. Therefore the Japanese accent is difficult for the Korean students, and the students form Kyungsang-do province tend to speak Japanese with the Kyungsang-do accent. The purpose of this study is to find out difficult sounds to pronounce and then present an easier way of teaching theme

오늘날 정보화가 빠르게 진행되면서 정보과학의 중요성이 수학, 과학의 중요성 못지않게 대두되고 있기 때문에 이 분야의 영재 역시 조기에 판별하여 교육시켜야 한다는 필요성이 강조되고 있다. 하지만 이에 대한 연구는 초보적인 단계에 머물고 있다. 이에, 본 연구에서는 영재의 판별에 대한 이론적 고찰을 통해서 영재의 특성, 정의 및 판별방법과 도구의 제작과정을 살펴보고 영재의 올바른 판별과정을 조사, 분석하였다. 또한 이를 바탕으로 정보과학의 기반이 되는 이산수학의 특성을 규정하여 이를 바탕으로 정보영재의 특성 및 정의를 내렸으며 이를 근거로 정보영재를 판별할 수 있는 도구를 제작하였다. 판별도구를 이용하여 적용한 결과 판별도구는 신뢰성이 있는 것으로 분석되었으며 향후 정보영재의 의미 있는 판별도구로 활용될 수 있을 수 것이다. Since the science of information is appearing no less important than mathematics and natural science as our society is rapidly becoming information-oriented, the necessity to distinguish prodigies of this field and to educate them as early as possible is also being emphasized. Unfortunately, however, the pertinent study is still in its beginning stage. In this study, I have reviewed the character, definition and method to distinguish prodigies and the procedure of developing a test, as well as researching and analyzing the proper process of distinguishing prodigies, through theoretical contemplation on the method of distinguishing the gifted children. Also, I have characterized and defined the information prodigies after clarifying the character of 'Discrete Mathematics' which becomes the basis of the science of information, paving the way to make a test method that can distinguish those information prodigies. As a result of our applying the system by using the distinction test, it turned out that the distinction test was pretty reliable. Accordingly, it can be utilized as a significant distinction test for information prodigies in the forthcoming future.

Background : Congestive heart failure after acute myocardial infarction relate to left ventricular systolic sysfunction. Also, left ventricular diastolic function contribute to heart failure. The aims of this study were, firstly to characterize left ventricular diastolic function by transmitral flow velocity, and secondly to study the significance of Doppler measurements in relation to the development of heart failure in the early phase of myocardial infarction. Method : Pulsed Doppler echocardiography of transmitral flow was assessed in 34 patients with acute myocardial infarction. According to the Doppler transmitral flwo velocity profile, the study patients were assigned to the three groups: normal filling pattern (DT > 140ms, IVRT < 100ms), relaxation abnormality (DT > 140ms, IVRT ≥ 100ms), pseudonormal or restrictive pattern (DT ≤ 140ms). Also, on the basis of the presence of heart failure during first week of hospitalization, the patients were divided into two groups: patients with no sign of heart failure (Killip class Ⅰ) and heart failure (Killip class Ⅱ-Ⅳ). Results : Of the 34 patients studied, 10(29%) were normal filling pattern, 17(50%) abnormal relaxation and 7(21%) were restrictive patterns. The left ventricular ejection fraction(EF, 40 ±6%) of restrictive pattern was significantly lower than that of normal filling pattern of abnormal relaxation(p < 0.01). And, the IVRT, DT, E/A and left ventricular EF were reduced in patients with heart failure(14 patients) compared to no sign of heart failure(20 patients)(p<0.05). Of the patients with heart failure, IVRT and left ventricular EF were reduced in patients with DT≤140 ms compared to DT> 140ms(p=0.001). Conclusion : Left ventricular diastolic dysfunction is present early after onset of symptoms of acute myocardial infarction. Assessment of left ventricular diastolic function complements measurements of systolic function in the evaluation of cardiac function. DT, IVRT, E/A and left ventricular EF are useful predictors for development of congestive heart failure following acute myocardial infarction.

전력선 통신(PLC)을 위한 모뎀 개발에 관한 연구

신관우,김용태,이윤섭 공주대학교 생산기술연구소 2001 論文集 Vol.9 No.-

PLC (Power Line Communication) is the communication method using the existing power line installed in houses and offices to convert and transmit high frequency communication signal from tens of KHz to tens of MHz, and receive the filtered signal using high frequency filter. The advantage of PLC is that PLC uses the existing power line installed in houses and offices so it does not require separate power line. Easy and convenient access using electric outlets is another advantage of PLC. However, PLC has some disadvantages such as limited transmission power, high load interference and noise, variable signal attenuation, characteristic of impedance, selective possibility of frequency property. This study designed the boiler temperature control system by unit using the modem designed on the basis of technology used for PLC modem. After conducting experiments with systems, it was possible to control stably. By commercializing this product, we can avoid unnecessary heating of separate temperature control unit, and save the cost accordingly.

Picric Acid에 依한 Disopyramide Phosphate의 抽出分光光度 定量

申台容 又石大學校 1990 論文集 Vol.12 No.-

A spectrophotometric method is proposed for the deternunation of Disopyramide phosphate. The method is based on solvent extract of the ion-pair formed between Disopyramide phosphate and colored Picric acid into 1, 2-dichloroethane. The extract should a maximum absorbance at 375nm The optimum pH range for the extraction is 2~7. The absorbance should a linear relationship to the concentration of Disopyramide phosphate 1×10^-5∼12×10^-5M. Continuous variation plots and mole ratio plots indicated a 1:1 Disopyramide phosphate-Picric acid ratio. The binding state of Disopyramide phosphate-Picric acid was presumed by IR spectra as intermolecular hydrogen boinding. This method was suitable for the spectrophotometric determination of Disopyramide phosphate in mixed pharmaceutical preparation.
