The construction works with concrete has the potential problems of water-tightness. The conventional treatments for water-tight concrete are not satisfactory in terms of strength and water-tightness. However, ACPC(asphalt coated portland cement), which was invented by Hong in 1972, was satisfactory in terms of water-tightness and compressive strength. ACPC was made by coating OPC(ordinary portland cement )with asphalt and adding with carbon black as pore filler in the rate of weight ranging from 0.1%to 0.9% respectively. The cause of permeation is the connection of crack and pore which are in the concrete. The purpose of this study was to find the optimum composition of ACPC according to the permeability test, the compressive strength test, and workability test. The major findings of this experiment are as follows; 1) The optimum composition of ACPC for water-tightness and compressive strength was found at 0.3% asphalt, 0.5% carbon black at the rate of the weight of cement in view of the economic consideration. 2) The compressive strength of the specimen of ACPC was lower than that of OPC in the case of aging of 7 days and 28 days but the compressive strength of the specimen of ACPC was higher that of OPC after aging 35 days. 3) The workability of ACPC was higher than that of OPC in through of the slump value test and fresh concrete air content test.

사이트 자치성은 분산 데이타베이스 시스템의 질의 처리 ,권한 관리 방식, 뷰 관리, 카탈로그 관리 등에 많은 영향을 미친다. 원거리 분산 데이타베이스 시스템에서는 사이트 자치성이 중요한 목적이 되지만, 근거리 분산 데이타베이스 시스템에서는 그다지 중요하지 않다. 이 논문에서는 분할 및 중복된 객체들을 제공하는 근거리 분산 데이타베이스 시스템의 전체적인 구조, 카탈로그 관리, 질의 처리 모델을 기술하였다. 질의 처리 모델은 통신 비용뿐만 아니라 사이트마다 서로 다를 수 있는 CPU 비용과 디스크 엑세스 비용을 모두 고려하였다.

短形導波管內의 연속 테이퍼에 依한 反射特性

洪義錫 光云大學校 1974 論文集 Vol.3 No.-

The tapered waveguide is regarded as a two-mode system, the modes being the forward and reverse waves. A reflection parameter can be defined, relating the amplitude of the reverse wave generated at a point in the taper to the amplitude of the forward wave at that point. The reflection parameter can be regarded as a coupling parameter between the two modes and coupled-mode theory can be used to obtain the overall reflection coefficient of the taper. A detailed analysis is given for the case of a homogeneously- filled tapered waveguide, with perfectly conducting walls, working in the dominant mode. The reflectionless tapers are constructed on theoretical back-grounds discussed in this thesis. The working freguency on design procedure is chosen 9 GHz. The measured results theoretical values are plotted on graph and compared with VSWR values of Linear tapers.

박기홍,김재욱,김의훈,김채옥 漢陽大學校 基礎科學硏究所 1992 基礎科學論文集 Vol.11 No.-

Y??NdxBa₂Cu₃O?? 고온초전도체의 X-선 회절 분석 과 적외선 투과율 측정은 실온에서 수행되었다. 또한 수송임계 전류밀도는 77K에서 측정되었고, 저항은 80~140K 범위의 온도에서 조사되었으며, 시료들은 고상 반응법에 의해서 제조되었다. 한편 x의 양이 변함에 따라서 전이온도 Tc는 88K 근처의 값을 가지며, 거의 x의 양에 따라 변하지 않았다. 적외선 투과율 측정에서 날카로운 peak들은 472.23~618.87㎝?범위에 있었다. 이것은 특이할 정도로의 low-lying plasmalike edge와 낮은 에너지의 전자적인 여기가 존재함을 나타내는 것이다. 수송임계 전류밀도는 22~92 A/㎠ 범위에 있었다. X-ray pellet diffraction and IR transmittance measurements were been carried out at room temperature. Also the transport critical current density and resistivity of high Tc superconducting Y??NdxBa₂Cu₃O?? system were determined at 77K and in the range of 80~140 K. The sample were prepared by solid state recation. As x varied, the superconducting transition temperature Tc near 88K did not depend on x. In the infrared transmittance measurements, several sharp peaks were observed in the range of 472.33~618.87㎝-1. This indicates that unusual low-lying plasmalike edge and low energy electronic excitation exist. The transport critical current densities determined ranged from 22 to 92A/㎠.

朴木月 詩 硏究 : 話者와 聽者의 關係類型을 중심으로

洪義杓 진주여자전문대학 1993 論文集 Vol.16 No.-

This is a Study on Mogwol's poetry. First, in his early 36 poems speaker and hearer do not appear in 22(61%) and only speaker appears in 11 poems(31%). And both speaker and hearer appear in 3 poems. Second, in the middle period of his poetry it shows the opposite phenomena. In his middle 103 poems speaker only appears in 70 poems(68%), and neither speaker nor hearer appears in 25 poems(24%) and both speaker and hearer appear in 8 poems(8%). Third, in his late 279 poems speaker alone appears in 199 poems(71%). Both speaker and hearer appear in 69 poems(25%) and neither speaker nor hearer appears in 11 poems(4%). Thus, the rate that speaker alone appears is increasing from 31% in the early poems via 68% in the middle poems to 71% in the late poems. Therefore Mogwol's poetry is speaker-oriented and represents speaker himself through consciousness. So most of thorn have lyrical form which represents the style of speaking himself.

木月詩와 心理的 距離硏究

洪義杓 진주여자전문대학 1991 論文集 Vol.14 No.-

This is a study on the psychic or aesthetic distance of Mogwol's poetry. The psychic or aesthetic distance in literature is the inner distance. So the psychic or aesthetic distance cannot be measured. The psychic or aesthetic distance is showed variously in line with poet's ability. In Mogwol's poetry, the underdistancing on account of the overexposure of emotion is showed in the poetry of the middle and the last years This is the reason why the speaker in the poetry outcrops the emotion on account of the attachment to man or his life too much in the poetry of the middle years. And the speaker in the poetry of the last years attaches to the Christian belief, so the poetry becomes to the underdistancing. The overdistancing on account of the underexposure of the emotion is showed in the poetry of the early years. This is the characteristic of the physical poetry and the speaker in the physical poetry suppresses his feelings. The proper aesthetic distance in Mogwol's poetry is showed in the poetry of the last years. The results of this is related to the attitude of the speaker in Mogwol's poetry.

자궁 경부 도말표본에서 Chlamydia trachomatis의 양성율에 대한 연구

홍기언,김의한,김민관,양승하,강상균 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.1

The uterine cervicitis by chlamydia trachomatis(CT) shows no specific clinical symptoms except mucopurulent leukorrhea, but it causes severe complications such as endometritis, salpingitis, abortion and infertility. Fortunately, the treatment of cervicitis by CT is simple and effective, so that this infection is once diagnosed and then confirmed, the treatment is not difficult. To study the positive rate of CT infection, we collected 65 patients inflicted with mucopurulent leukorrhea in Chonan city. Specimen was collected by swab and for the detection of CT, ELISA was carried out. The positive cases are observed in 15 out of 65 patients (positive rate is 23.1%). This positive rate was rather lower than other reports, however, this results were higher we expected With this result, the clinicians keep in mind the fact that the causes of uterine cervicitis by CT occupy the large proportions as gonorrhea.

金東仁 小說 硏究

洪義杓 진주여자전문대학 1990 論文集 Vol.12 No.-

This is a study on 'Baetaragi', Kim Dong-In's novel. The first, its plot is a kind of frame-story. It has three frames. They are the outer story, the inner story and the inner main story. The inner main story is the most important part in the novel. At the beginning the outer story is introducted. And the inner story, which connects the outer story and the inner main story, is unfolded. The second, time in this novel consists of two parallel axes of time. One is time of fiction and the other is time of narration. In this novel, time of narration progresses in order for one year. On the other hand, the inner main story is composed of the story in the past and the outer one is composed of the story in the present. The third, the writer takes advantage of the technique of description which appeals to the readers' sensory organ. Especially he appeals to the organ of vision. And he really describes the mental state of the characters well by using sensual description and the dialect.

땅이름의 유래에 대한 연구 : 합천지역의 마을이름을 중심으로 Centering on the village names in Hapchoˇn Area

홍의표,문병우 진주여자전문대학 1996 論文集 Vol.19 No.-

I have analyzed the origin of village names in Hapchoˇngun. I found that the origin of village names must not be taken as the current names as I examined over the origin of village names on the basis of anon-the-spot survey and information gathered from the information. For many of the current village names have undergone a great change for a long time and have been fixed. Thus I suggest that we should consider the original figure and meaning of the words. I found out the key to see the root of village names. I examined that there were many of the same names among the village names in pure Korean even though I examined them in a limited area. I think there is a general principle by which proper names are given to villages. This study showed that many of the village names had been given according to the value and topography of the place. Hence what we should do for the future is to establish the general principle for naming places by examining the rest of village names and the origin of all the places names such as mountains, rivers, and hills.
