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.

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

이동 호스트를 위한 계층적 멀티캐스트 경로 재설정

신용태,김선집 崇實大學校 2000 論文集 Vol.30 No.1

A Mobile computing environment allows hosts to roam while retaining access to the Internet. Multicast is communication between a single sender and multiple receivers on a network. In this paper, we consider the difficulties which transpire when providing multicast to mobile hosts during times they are not located their home network. Providing multicast in an internetwork with mobile hosts is problematic because the established multicast delivery paths may frequently restructure along with host migrations, incurring overheads. We present a new strategy which provides multicast to mobile hosts while keeping a low overhead in adopting multicast routes to mobile host locations. This is achieved by partitioning the mobile environment into intra-region, intra-domain and inter-domain, which is hierarchical. So that changes in the multicast routes due to host intra-region movements are hidden from other regions, intra-domain movements are hidden from other domains. In a performance evaluation, our approach is compared with the best known proposal and shows that is reduces the multicast latency and route reconstruction overhead.

산화구리에 의한 배기 가스 중의 아황산 가스 제거 : 반응속도에 관한 연구 A Kinetic Study

신창섭,노용우,이태희 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.2

The reaction of cupric oxide powder with 2% sulfur dioxide was investigated over a temperature range of 300-500℃ and over a particle size range of 0.051-3㎜. The experimental data were correlated well by the shrinking unreacted core model and the optimal reaction temperature was found to be 450℃. With average particle diameter less than 1㎜ and superficial gas velocity higher than 8.8 ㎝/sec, the reaction of cupric oxide powder with sulfur dioxide was found to be controlled by the chemical reaction and the intrinsic rate constant was k=8987 exp(-8134/RT).

Picric Acid에 依한 鹽酸 Verapamil의 分光光度 定量

申台容,安文圭 又石大學校 1991 論文集 Vol.13 No.-

A spectrophotometric method is proposed for determination of VP. The method is based on solvent extract of complex formed between VP and colored PCA into chloroform. The optimum pH range for the extraction is 3.0∼6.0. The binding ratio of VP-PCA complex was presumed as VP-1 to PCA-1 by means of continuous variation and molar ratio. Beer's law is obeyed over the range of VP concentration 1×10 5^M∼1.2×10 4^M. The complex was differentiated from physical mixture of the two compounds by IR spectroscopy and the exsistance of intermolecular hydrogen bonding between the basic nitrogen of VP and the OH group of PCA was confirmed. This method was suitable for the spectrophotometric determination of VP in mixed pharmaceutical preparation.

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.

We investigated the effect of aqueous extract of Ammomum xanthioides(AXAE) on immediate hypersensitivity. AXAE inhibited systemic anaphylaxis induced by compound 48/80 in mice. AXAE inhibited serum histamine levels induced by compound 48/80 in mice. Moreover, AXAE dose-dependently inhibited histamine release in peritoneal mast cells activated by compound 48/80. These results indicate that the AXAE may be benificial in the regulation of immediate type allergic reaction.

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.
