홍원표,황의환 충남대학교 공업교육연구소 1984 論文集 Vol.7 No.1

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.

Purpose : Diagnostic estimation of destruction and formation of bone has the typical limit according to capacity of x-ray generator and image detector. So the aim of this study was to find out how much it can reproduce the shape and the density of bone in the case of using recently developed dental type of cone beam computed tomography, and which image is applied by new detector and mathematic calculation. Materials and Methods : Cone beam computed tomography (PSR 9000N, Asahi Roentgen Ind. Co., Ltd., Japan) and soft x-ray radiography were executed on dry mandible that was already decalcified during 5 hours, 10 hours, 15 hours, 20 hours, and 25 hours. Estimating and comparing of those came to the following results. Results : The change of inferior border of mandible and anterior border of ramus in the region of cortical bone was observed between first 5 and 10 hours of decalcification. The reproduction of shape and density in the region of cortical bone and cancellous bone can be hardly observed at cone beam computed tomography compared with soft x-ray radiography. The difference of decrease of bone density according to hours of decalcification increase wasn’t reproduced at cone beam computed tomography compared with soft x-ray radiography. Conclusion : CBCT images revealed higher spatial resolution. However, contrast resolution in region of low contrast sensitivity is the inferiority of images’ property.

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.

합천 지역어 연구 (Ⅰ) : 마을 이름을 중심으로 Centering on village names

홍의표,문병우 진주여자전문대학 1995 論文集 Vol.18 No.-

In this thesis I have investigated the property of a vocabulery morphology, and phonology represented in the village name which it being used at present from synchronic point of view and have researched with a to tracing a proper language which remains. The result is as follows. 1 First of all, I have investigated an etymology, distribuyion, a meaning cateory and so on etracting twenty kinds or so from the latter elements represented in the village name at habch'on area. The latter elements are divided into what is exclusively used temporarily from a general word and what is used as a latter element and though it is exclusively used from a genera word, Only base from comes out in a general word and an allomorphy is used only as the latter element in a place-name. 1) The temporarily exclusive use from a general word. -ku˘ri, -kol, -mog, -pawi, -nae, chngo˘, -t'o˘, -tu˘l, -pat', -san, -mit' 2) The latter element use in a place name. -tam, -ttu˘m, -mal, -sil, -choˇm, -kae, -ma, -tal, -mi 3) The exclusive use from a general suffix. -i 4) Seen from diachromic point of view, -tal, -tam, -sil and dhat not were originally a free from but lost thir self-reliamce to become bard into a bound from and come out as a latter element in a place-name. 2. There are many case the latter element in a place-name is expanded extensively to be used exclusively as a village-name, a main meaning and a topogra phical name which has flexibility rather tharn it is limitedly used as a main meaning. -ko˘ri, -kol, -pawi, -i, -cho˘ng, -t'oˇ ete apply to this case as a latter element. 3. I have thought that it is glad to derive an old form of lexical element from our proper village names gradually wearing out by the social change and living environment. Basic lexical elements used in the place names disuppear by degrees, and they now seems to be little adopted when new place names are given. chash, t'ung, ha kal, sil and tal. And besides, I could find 'tarari', one of the place names in ssangch'aeg myoˇn. I wonder whether this word show that this area is 'tara-nation'. I think that much yet remains to be studied and examined. 4. In morphological consideration, I analyzed the morphemes of village names, dividing them into M1+M2 and Ml+M2+M3, extracting many word-constructions according to the combination of immediate constituents. In particular, it is noticed that the word-construction [N+V] (mul+koˇnnoˇ) come out in place names. 5. In phonological consideration, I classified the phonological phenomenon in village names into consonant varialile and vowel variable : assimilation, deletion, and palatalization in consonant variable, and deletion, Umlaut phenomenon, monophthong, and adhesion phenomenon of 'i'vowel variable.

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.

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.
