본 연구에서는 중심부를 MMA 개질 폴리머 모르타르로 하고 양표면부를 고인장, 고내구성인 GFRP (Glass Fiber Reinforced Plastics)로 보강하여 샌드위치를 제작하고, 이에 대한 단순 휨시험을 실시하여 GFRP 보강 MMA 개질 폴리머 모르타르 샌드위치패널의 단면결정시 필요한 설계 휨 모멘트의 산정을 위한 기초적인 자료로 제공코저 한다. 그 결과 중심부 MMA개질 폴리머 모르타르의 두께에 관계없이 압축 및 인장 GFRP 보강층 두께가 0에서 1.50∼2.76mm로 증가함에 따라 휨강도는 2.3∼5.6, 변형에너지는 40∼70배 보강효과를 나타내었다. 이것은 얇은 두께를 갖는 휨부재의 보강에 철근 또는 메쉬를 사용하는 것 보다 양표면부를 GFRP로 보강하는 것이 현저한 보강효과가 있음을 보여주는 결과이다. In this study, a MMA modified polymer mortar sandwich panels was developed : Core was made of the MMA polymer modified mortar, compressive strength of which was about 1020 kgf/㎠, and both facing were made of the glass fiber reinforced plastics (GFRP). The result showed that the strain energies increased 23-33 times as the thicknesses of facings increased from 1.50 to 2.76mm with fixing the core thickness to constants (30-50 mm). On the other hand, these values showed a tendency of decreases as the core thickness increases regardless of thickness of facings. A set of basic data for the structural analysis could be provided by investigating the correlations, within the scope of this research, between the resisting moment and the thicknesses of core and facing.

不織布의 構成條件에 따른 壓縮彈性의 變化에 관한 硏究

金泳錫,申鉉世 崇田大學校 1983 論文集 Vol.13 No.1

Lately, non-woven fabric is used for materials of industry, and the uses of the fabric are increasing continuously. The purpose of this study is to investigate the difference of compressional properties in various structures of non-woven fabrics and is to research into the effective forming conditions to improve the quality of above fabric. The results of this study are summarized as follows; 1) If non-woven fabric has same packing factor, the works of compression and recovery are increasing proportionally by the increase of thickness. 2) If non-woven fabric has same thickness, compressibility is decreasing proportionally by the increase of packing factor. 3) The compressional properties of non-woven fabric are related deeply to the properties of composed fibres. The good compressional properties are obtained when composed fibre has a good elastic recovery. From the above results, it is recognized that suitable fibre, thickness and packing factor are very important conditions in manufacturing of non-owven fabric.

중·근세 국어 연구에 대한 반성 : Based on Morphology and Lexicon 형태와 어휘를 중심으로

김영신 新羅大學校 1983 論文集 Vol.14 No.-

This study aims to review the studies on the morphology and vocabulary of Middle Korean and Early Modern Korean which have been worked out so far by many scholars in an attempt to correct some mistakes if any and provide their alternatives. One of the reasons for the possible mistakes is probably that not many data concerned were referred to. No doubt, it is never easy to consult so many referential data coming to some hundreds, but it is required that we examine thoroughly all the data concerned if we want to obtain convincible findings. Some of the mistakes and their correct alternatives which are provided in this study are summed up as follows: 1. "??"(저녁, 夕) is not the compound of "??"(彼) and "??"(岸) but the compound of "??"(져믈-) and "??". 2. "??"(더위잡-) is not a derivational word but a compound word. 3. The base of "naon, naontja"(나온, 나온댜) is "nap-"(납-, 樂). 4. The base of "??"(??) is "??"(??). To add up a final word, I'm afraid that I have criticized the arguments of the predecessors' studies too impudently.

「석보상절」의 어휘 연구

김영신 新羅大學校 1983 論文集 Vol.15 No.-

Seogbosangjeol can be considered as a representative reference of the korean prose in the fifteenth century. The seven Books (Book 6, 9, 11, 13, 19, 23, 24) of Seogbosangjeol which are transmitted until now might contain a sufficient lexical entries. The synthetic lexical research, however, is not made, so that the aims of this paper are to look over the entire lexical entries, to write down their index, to reveal their meanings and structures, to find uncommon words, and to study the diachronic significance of Seogbosangjeol. it is quite regrettable that the dta in the Book 3 of Seogbosangjeol which is said to be discovered recently are not quotated in this research since the book cannot be obtained. Therefore, the book should be known to everyone sooner or later. The results of this research will be given as follows; 1. Seogbosangjeol contains 1428 genuine Korean words, and 1950 Sino-Koreans. 2. It contains about 100 uncommon words. 3. There are 8 words that can change their meanings. 4. It contains many derivtive words added by affixes. The patterns are given as follow; a. Noun→Verb b. Adjective →Verb c. Verb→Verb d. Noun→Adjective e. Verb→Adjective f. Verb→Adverb g. Adjective→Adverb h. Verb→Noun i. Adjective→Noun j. Noun→Noun k. Adjective→Determiner 5. The lexical compound words amjong the compound has the forms, as given by a. Noun+Noun b. Noun+Verb(Adjective) c. Adverb+Verb 6. The root of ?? , ?? , ?? 'to obtain' can not be explained until now. sitc??p??e in the page 20 of Book 24, however, proposes a good confirmation that the root of three examples is just sit-.

「박 통사 상」 (朴通事 上)의 연구

김영신 東亞大學校 國語國文學科 1976 국어국문학 Vol.1 No.-

To study analytically a Korean biblioraphy which deserve to be called a classic and to examine its orthography, phonology, vocabulary and grammatical rules will contribute to the study of the Korean language at a given time and indicate the correct direction of its study in its historical setting. This essay is based on 'the First version of Bak Tong Sa, Book 1' printed by the Kyong Buk University Press. I have organized the linguistic materials in the same book and have added some views of my own. There are three different Korean version of the Bak Tong Sa. The dirst was done by some twelve scholars including Byon Sum(邊暹) and Bak Se Wha(朴世華) at the time of king Suk Jong(肅宗) in 1677; another, which was named 'the New Version', by Kim Chang Jo(金昌祚) in 1765, King Yong Jo's(英祖) time; and then the last one on which this essay is based. This last one is, however, believed to have been compiled by a scholar, Choe Se Jin(崔世珍) sometime between 1506 and 1517 at time of King Chung Jong's(中宗) reign and the only copy now belong to Cho Sung Mok(趙誠穆) at the town of Sang Ju in Kyung Buk(慶北 尙州邑) Province. In May, 1959, the Research Room of the Korean Language and Literure attached to the Graduate School of Kyong Buk University succeeded in gaining access to this version and printed it under the title, 'Materials of The Korean Literature Book 4.' Therefore, of the three versions already mentioned, this is the oldest version and it will be referred to as 'the New Version' in my essay. A book, 'Jung Bo Mun Hyon bi Ko, (增補文獻備考) 'literally Meaning the enlarged bibliographical reference, has a passagge which suggests that the Korean Version done by Choe Se Jin had originally three separate books. Accordingly we can safely imagine there should be two more books beside this one in question, but, to our great regret, none have been able to locate them. Bak Tong Sa, as well all know, was a Chinese language text book for Korean students and it is written in the Chinese characters and is translated into Korean below the text. The translation was done, it is believed, completely in the collequialism in the latter part of the fifteenth century or in the early sixteenth century. The vivid collequial style of the common people then has no equal the field of classic works. In comparison, the Song Gang Ka Sa(松江歌辭), for instance, is somewhat stiff and formal in its versification, and the Du Si En Hae(杜詩諺解), with its word-by-word translation is rather flat. This essay does not cover a bibliographical study. Main emphasis is put on phonology, vocabulary, and grammar and some corrections, if need be.

This study was carried out to decect efficient method of sucker control classifed by cultivation hectarage per farm in 57 farms selected in the main producing districts of flue-cured and burley tobacco. In topping, it was no difference of working hours by cultivation hectarage per farm in flue-cured and burley tobacco. Suckering was the best in working hours among working type, and the more cultivation hectarage per farm was small, the more working hours of topping, suckering and application of suckercide was increased. Application of system suckercide shows a decrease as compared with application of contact suckercide but the decrease of working hours in application of contact suckercide by cultivation hectarage per farm was larger than in system suckercide. 경작면적별 효율적인 곁순억제방법을 알아보고자 황색종 및 버어리종 주산지에서 57개 경작농가를 선정하여 조사한 결과를 요약하면 다음과 같다. 1. 적심작업의 경우 황색종과 버어리종 모두 경작면적에 의한 노력소요량의 차이는 없었다. 2. 곁순제거작업은 다른 작업에 비해 노력소요량이 가장 많았고, 경작면적이 작을수록 노력소요량이 증가하였다. 3. 황색종과 버어리종 모두 침투성 곁순억제살포작업에 비해 접촉성 약제살포작업에서 노력소요량이 많았으나 경작면적이 큰 경우 접촉성 약제 살포작업 노력소요량 감소폭이 침투성 곁순억제제 살포작업에 대한 노력소요량 감소폭보다 컸다. 4. 각 작업에 대하여 농가간 최저 및 최고 노력소요량 차이가 큰 것으로 나타나 조사방법과 시기를 보완하여 보다 체계적이고 세밀한 조사가 추가적으로 이루어져야 할 필요가 있다.

정재훈,김영신,임흥빈,석영선,신주식,이학수 충북대학교 연초연구소 2004 煙草硏究 Vol.19 No.-

본 실험은 type별 흡연 장치의 담배 주류연 포집에 대한 차이를 비교하고자 주류연 중 일반적인 다량의 성분을 측정하였다. 1. 니코틴 함량은 대체로 linear-type 흡연 장치에서 높은 경향 이였으나 유의한 차이는 없었다. 2. 수분 함량은 두 가지 type 간에 유의한 차이는 없었다. 3. tar 함량은 저 농도에서 linear-type 보다 otary-type 흡연 장치가 높은 경향 이였으나 유의한 차이는 없었다. 4. 일산화탄소는 rotary-type과 linear-type 모두 유의한 차이는 없었다. 본 실험결과 ISO 표준 흡연 조건에서 담배 주류연의 tar, 니코틴, 일산화탄소 함량의 측정은 흡연 장치의 type별 통계적으로 유의한 차이는 없는 것으로 판단된다. This study was conducted to compare rotary-type with linear-type automatic smoking machine referred to ISO 3308 in the determination of tar, nicotine and CO in cigarette smoke. Sample were used with 4 kinds of domestic branded cigarettes(tar ; 1, 3, 6, 10 mg/cig) and CORESTA Monitor 4 cigarettes(tar ; 14 mg/cig). Tar and nicotine contents were analysed by gas-chromatograph methods in accordance with ISO 4387 and 10315-1. Determination of carbon monoxide in the vapour phase of cigarette smoke was meaured by NDIR method in ISO 8454. Sample preparation were performed in conditioning room at 22℃, 60 % for 48 hours according to ISO 3402. There was no significant difference between two smoking machine from 1 mg/cig to 14 mg/cig tar cigarettes, but, the contents of three components measured by rotary type showed higher tendency than those by linear type in the case of hight tar cigarettes. The results were the opposite in low tar cigarettes.

당뇨병과 관련된 정신병리 : 정신증상, 특히 우울증상을 중심으로 Deal with Psychiatric Symptoms, Especially Depressive Symptoms

This study was performed to find out psychopathological characteristics related with diabetes mellitus(DM) in comparison with known DM patients, newly diagnosed DM patients, normal subjects. These three groups were examined with Beck Depression Inventory(BDI) & Symptom Check List-90-Revision(SCL-90-R). The results were as follows : 1) Known DM patients showed significantly higher scores on BDI, and all subscales of SCL-90-R than normal subjects. 2) The BDI score of known DM patients was simillar with newly diagnosed DM patients while known DM patients showed significant differences in comparison with newly diagnosed DM patients on Depression and Obsession subscale in SCL-90-R. 3) The content of depressive symptoms of known DM patients was similar with that of newly diagnosed DM patients. 4) Newly diagnosed DM patients showed higher tendency on BDI score and Interpersonal sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety subscale score of SCL-90-R than normal subjects. 5) There were no differences in BDI score and all of SCL-90-R subscale score according to prevalence of DM except somatization subscale. Our study suggests that depression may be predisposed to DM and the man who has high interpersonal sensitivity, anxiety, hostility, phobic anxiety is more susceptible to DM. Futhermore, DM makes worse preivious psychopathology probably. Therefore in the management of DM, it is important to treat them according to the aspects of depression and other psychopathological characteristics.

An analysis on the load-bearing capacity of floor frame and body structure is investigated by the three dimensional rigid frame analysis. The load-bearing capacity of the body structure is estimated on the basis of comparison to the floor-frame-only structure. The location and magnitude of the maximum displacement are also determined and show good agreement with those of a previous study.In the present study the load-bearing capacity of the floor frame of van-type structures is about 80 percent of the total loadings.
