        오덕호 국제기독교언어문화연구원 1997 기독교언어문화논집 Vol.1 No.-

        Duck Ho Oh.1997. A Study of the Narrative Degree in the Gospels. Collected Papers on Christian Language Culture, A narrative shows a complex system of tellers or voices located on various levels (narrative degrees) of the discourse. Narrative degrees are determined by who the teller is and who the audience is. Since the meaning of the passage is profoundly influenced by the teller and the audience of the passage, the study of the narrative degrees of the Gospels is crucial to understand them. Several important merits of the study of the narrative degrees are to help the reader 1) to decide the extent of a passage: 2) to find the unity of the passage; 3) to recognize the irony of the text; and 4) to understand the message of a text more clearly (Honam Theological University & Seminary)

      • 혈중 젖산농도를 지표로 한 고령자의 전신운동 효과에 관한 연구

        정일호,김덕중 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.3

        This study is to identify the effect of moderate endurance exercise based on blood lactate accumulation. 8 volunteers who live in S-Gu and are over 65 tears, were separated in two groups. One is exercise group(EG) consisting of 5 people and the other is control group(CG) consisting 3 people. Research was carried out for 12 weeks. Results were as follows: 1. VO₂ change EG have shown insignificant statistical change with approx. 3.74ml/㎏/min increase in max. VO₂ while CG have shown approx. 7.19ml/㎏/min(p<0.05) increase compared to normal status. It is considered that the amount of physical for CG have increased since they routinely take exercise program at a senior center. 2. Blood Lactate accumulation change Incremental change of blood lactate accumulation under full-load execise for EG have indicated approx. 1.81mmol/l(p<0.05) increase during 6 minute of the test while that of CG have decrease. However, the decreasing tendency was not that much meaningful.

      • 소음·진동에 따른 참전복(Haliotis dissus hannai)의 행동·생태학적 변화

        최상덕,정형택,윤호섭,안치영,이삼노,이우범 國立 麗水大學校 환경문제硏究所 2001 環境硏究論文集 Vol.4 No.-

        These days, the underwater excavation and the piling work have been commonly used to reclaim land and to build a breakwater. As the piling work generates high underwater sound pressure in all direction, various kinds of marine organisms are largely affected even if they live a long distance from the piling work. Therefore, this paper describes the relationship between the behavior of abalone(Haliotis discus hannai) of 50cm long and the environmental noise level with vibration due to the piling work. We have separated the research into two parts. The one is continuance impact, the other is intermittent impact. The following are the results obtained from the present investigation: Comparing 0.5cm/sec vibration with 50dB noise and 0.9cm/sec vibration with 60dB, the previous one show a faster reaction speed than the later one. Futhermore the later one showed that pulling up on their shell, in order to avoid the epidemic, moving around, small organisms are included to hide under big organisms, alerting posture. However we couldn't find a consistent standard in our research.

        나노기술을 이용해 제작한 불소함유 접착필름의 치아우식증 예방효과

        박덕용,이난영,이상호 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

        필름 형태의 새로운 불소 delivery system을 개발하고 이에 대한 치아 우식증 예방효과를 기존의 전문가 불소 도포 제재인 APF gel 및 불소 바니쉬와 비교 평가해 보고자 하였다. 소의 법랑잘 시편에 APF gel (60 seconds taste^(?), 1.23% APF, PASCAL, USA)과 불소 바니쉬 (CavityShield^(?), 5% sodium fluoride, Ominii Pharmaceuticals, USA), 그리고 최근 개발된 3% 불소 함유 필름, 5% 불소 함유 필름 시제품을 도포한 후 인공 우식을 유발시켜 표면미세경도와 병소깊이를 측정하 여 다음과 같은 결과를 얻었다. 1. 실험군과 대조군의 표면미세경도의 차이는 II군, IV군, III군, I군의 순으로 컸으며, I군은 II군, III군, IV군에 비해 유의한 차이가 있었으나, II군, III군, IV군 간에는 유의한 차이가 없었다. 2. 실험군과 대조군의 병소 깊이의 차이는 II군이 가잣 컸으며(P<0.05). I군이 가장 작았다(P<0.05). III군과 IV군은 유의한 차이가 없었다. 이상의 결과로 미루어 보아 새로 개발된 불소 전달 사스템인 불소 함유 필름은 불소 젤보다 치아 우식증 예방효과가 우수한 것으로 나타났으며, 불소 바니쉬와 유사한 효과를 나타내었다. The purpose of this in vitro study was to evaluate the effect of fluoride containing adhesive film on prevention of enamel demineralization. Eighty bovine enamel blocks were divided randomly into 4 groups of 25: (1) APF gel applied ; (2) Cavityflhield™ applied; (3) 3% fluoride film applied; (4) 5% fluoride film applied: Early caries lesions were produced by placing each specimen into demineralization solution at pH 4.0 for 72 hours. Then lesion of the surface microhardness were measured by the Vicker's hardness test and the lesions depth were measured by polarizing light microscope. The results of the present study are as follows: 1. Difference of microhardness value (M±SD) between control and experimental side was the highest in group II, followed by group IV, III, I but, no significant difference was between group II, III and IV. 2. Difference of mean lesion depth (M±SD) between control and experimental side was the highest in group II, followed by group III, IV and I but no significant difference was between group III and IV. The results of the present study indicate that the fluoride film application is more effective than APF gel and is similar to fluoride varnish application for prevention of dental caries.

      • DENAR교합기 사용시 INTEROCCLUSAL RECORD의 정확도에 관한 연구

        김덕송,진태호,조혜원 圓光大學校 1991 論文集 Vol.25 No.2

        This study was performed to investigate the accuracy and availability of the interocclusal recording materials for Denar articulator and compare with the accuracy of the Pantronics. 15dental students in Wonkwang University were paticipated in this study and interocclusal recording materials used in this study were Wax(Modelling wax, Dentrey, England), Corpl wax(Surgident, Columbus Dental, U.S.A.), Impression compound(Pericompound, G-C, Japan)and Impression plaster(Xanthano, Bayer, Germany). The immediate side shift and protrusive condylar guidance were measured from Denar articulator(MarkⅡ,Denar Corp.) and Pantronic(Denar Corp.) The obtained results were as follows: 1. The mean values of left and right immediate side shift were some higher with Impression plaster and Wax, but there were no statistical difference. 2. The mean value of protrusive condylar guidance was higher with Impression compound, but there was no statistical difference. 3. All interocclusal recording materials used in this study were available for interocclusal record.

      • 螢光燈의 磁氣場에 의한 影響調査

        朴德圭,金銀伶,琴慶浩 慶北大學校 1991 論文集 Vol.51 No.-

        In this study, it was observed that the discharge voltage is increased(Vd ∝ H), the discharge current and luminous intensity are decreased(L ∝ H^2) as the magnetic field intensity(H) applied on the several commercial fluorescent lamps is increased. Magnetic insulation is appeared in the condition that critical transverse magnetic field is applied on the fluorescent lamps. At that condition, discharge current is reduced very low level, and then glow is disappeared. As the length of the lamp tubes is decreased, magnetic field intensity has to increased in order to occur "magnetic insulation". The experimental relation between critical magnetic field intensity for magnetic insulation anil the length of the lamp tubes (H^*d_eff/V_d^(1/2) = A) is obtained.

      • 시그마 환에서의 위상

        李德浩 공주대학교 사범대학 과학교육연구소 1992 과학교육연구 Vol.23 No.1

        Σ를 집합Ω의 부분집합들의 σ-환 이라할 때, Σ에 위상을 정의하여 Σ를 위상 σ-환으로 만든다. 이 위상을 τ라 할 때, Σ에서의 단조 감소(증가)하는 집합렬 E??은 수렴하고 그 극한은 ∩??E??(∪E??)과 같다. X가 어떤 집합일 때, X의 net의 극한을 정해주므로서 X에 위상을 줄 수 있다. 이 논문에서는 (E??)이 Σ에서의 집합렬일 때, E??이 E??·Σ에 수렴한다는 것을 임의의 ??∈Ω에 대하여 자연수 N이 존재하여 모든 n≥N에 대하여 ??E??△E인 것으로 정의한다. 이 극한의 정의에 의하여 Σ에서의 위상 τ가 일의적으로 정해져서 τ-수렴하는 모든 집합렬의 집합이 위 극한의 정의에 의해 수렴하는 모든 집합렬의 집합과 일치한다. 이 논문에서는 위상 τ에 대하여 연구하고 다음 결과를 얻었다. (1) (Σ,τ)는 Hausdorff공간이다. (2) (Σ,τ)는 Sequentially compact이다. (3) 함수 λ:∑→X가 연속일 필요충분조건은 임의의 (E??) Σ에 대하여 E??→E이면 λ(E??)→λ(E)인 것이다.
