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.

To investigate the effect of maternal job activity on the preterm delivery, low birth weight infant and spontaneous abortion, 1646 delivery data were analyzed from Jan. 1991 to Dec. 1992 in Chungnam University Hospital. The results obtained were as follows; 1. The percentage of subjects who had job during pregnancy was 20.3% and the variables of maternal age, education level, prepregnancy weight, maternal height, number of abotion showed significant difference in the distribution of subjects whether they had job or not. 2. There were no significant difference between the group who had job during pregnancy and those who had no job in the mean gestational period, number of spontaneous abortion, rate of preterm delivery and spontaneous abortion. However mean birth weight and rate of low birth weight showed significant difference between the groups. 3. The rate of preterm delivery of the group who had job were higher than those who had no job activity in the subgroup of 35 years or more age, prematurity history presence, 2 or more abortion history, obstetric complication presence, but there were no significant difference. The rate of low birth weight also higher in the group who had job than those who had no job activity in the same subgroup except obstetric complication presence. 4. The rate of spontaneous abortion of the group who had job were higher than those who had no job activity in the subgroup of 35 years or more age, below high school, height of 163cm or above, but there were no significant difference. 5. Rate of preterm delivery still showed better results in the group who had job than the group who had no job when adjusted for variables related, but there was no statistical significance. 6. Rate of low birth weight still showed better results with statistical significance in the group who had job than the group who had no job when adjusted for variables related. 7. Spontaneous abortion had occured less frequently in the group who had job than the group who had no job when adjusted for variables related. 8. Rate of preterm delivery and low birth weight were lower in the group of teacher, bank clerk, medical personnel, citizen servant than the group who had no job, but higher in the job of company employee, commerce. Spontaneous abortion was most frequent in group of commerce, and the group of teacher, company employee showed higher rate of abortion than the group who had no job.

Three different treatments for induction of estrus in Korean native black goats were compared: follicle stimulating hormone(FSH, FSH-p^TM), FSH combined with MAP(intravaginal impregnated sponges, Veramix^ⓡ, containing 60 ㎎ medroxy progesterone acetate for 14 days), and FSH combined with progesterone(Ovaron^ⓡ, 10 ㎎ IM for 10 days) and PGF_2α(Lutalyse^ⓡ, 3 ㎎ IM at first FSH injection). FSH for inducing estrus and superovulation was given a total 20 ㎎ intramuscularilly in decreasing dosage injections twice daily over 4 days. The MAPs were withdrawn at the 3rd day of FSH injection. Estrus observations were conducted every 6 hours from last FSH injection for 24 hours by placing the does with fertile male goats. Estrus and superovulation were more successfully induced with treatment of MAP + FSH than other treatments(FSH only, or progesterone + PGF_2α + FSH) (estrus induction; 100 vs 42.8 and 71.4%, ovulation points; 11.4 vs 5.4 and 4.4, respectively). The effect of gonadotropin releasing hormone(GnRH) on the ovulation rate was also examined. However, no difference was observed for inducing ovulation with treatment or dosage(100 ㎍ 200 ㎍) of GnRH. Low midline laparotomies were performed, and then ovarian responses (ovulations and follicular development) were examined by exteriorization of the reproductive tracts. Ova were recovered from oviducts by retrograde flushing 60-146 hours after MAP removal, and were classified the developmental stages. Overall 66.1% (236/357) of recovery rate was obtained from 30 superovulated does. The optimal recovery time of microinjectable 1-cell zygotes was approximately 72-76 hours after MAP removal.

The current study evaluates the capacity of Caryophylli Flos water extract(CFWE) to regulate immediate allergic reaction by control of histamine release. 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.

급성 심근경색 초기에 도플러 심초음파를 이용한 좌심실 이완기 기능의 평가

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.

신용승,김태형,윤종학,노승남,이철구 서울産業大學校 2002 논문집 Vol.53 No.1

The shot peening process is most often used to improve fatigue properties of metal parts. In order to achieve optimum, repeatable and reliable fatigue enhancement from the shot peening process, the important shot peening parameters must be controlled. In this paper, the optimum shot peening condition is investigated. Rotary bending fatigue test was accomplished to investigate the effects of shot peening on the fatigue strength. Experimental results show that the fatigue strength was tremendously increased by optimum peening.
