        하악이부와 두개안면골격의 상관성에 관한 측모두부방사선 계측학적 연구

        노상호,이기수,박영국 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.1

        안모의 수직적 부조화에 부합되는 하악이부 형태에 관하여 보고되어 왔다. 이연구는 하악이부의 형태적 변이와 두개안면골격의 수직적 변이사이에 상관성을 관찰하기 위하여 시행되었다. 성인 남녀 부정교합자 212명의 측모두부 방사선사진에서 이부의 후경과 고경을 계측하고 이부비를 산출한 후, 이부비 평균-1 표준편차에 포함되는 측모군(low symphysis군)과 이부비 평균+1 표준편차에 포함되는 측모군(high symphysis군)으로 분류하고, 이들의 측모두부방사선사진을 계측하고 비교 분석하여 다음의 결론을 얻었다. 1. 이부비가 크면 hyperdivergent face이고, 이부비가 작으면 hypodivergent face가 되는 경향을 보였다. 2. 이부비가 크면 하악각도 컷으며, 이들 사이의 상관성은 높았다. 3. 이부비와 수직안면 고경사이에 중등도의 상관성이 있었으며, 특히 이부 후경과 전안면고경사이 및 이부 고경과 후안면 고경사이에도 중등도의 상관성이 있었다. 4. 이부의 형태적 변이와 설골의 위치사이에는 상관성이 없었다. The configuration of mandibular symphysis is likely to be dependent upon the genetic predeterminants and/or compensatory adjustments onto functional demands. The interrelation of morphological distinctives of symphysis in conjunction to the craniofacial skeleton had been scarcely anecdotal, therefore, the objective was to determine the correlation of morphological modifications between the mandibular symphysis and craniofacial complex. Lateral cephalometric headfilms of 212 subjects were employed for the conventional measurements. The proportion of chin height against chin depth length was referred as chin ratio, then, Low Symphysis (LS) and High Symphysis (HS) groups were turned out by means of the chin ratio. These samples yielded 35 in LS and 35 in HS groups. The data per capita were statistically analyzed and the following results were drawn ; 1. Overall characteristics of the craniofacial skeleton in HS group manifested hyperdivergence and LS group showed hypodivergence. 2. Gonial angle increased as chin ratio increased and was highly correlated to the chin ratio. 3. The chin ratio presented high correlation to the vertical face height, especially in terms of the chin height to anterior face height and the chin depth to posterior face height. 4. The morphological configuration of chin was hardly correlated with hyoid bone position.

      • 마이크로 박막 유량센서의 제작

        노상수,최영규,정귀상 경북대학교 센서기술연구소 1997 센서技術學術大會論文集 Vol.8 No.1

        Pt thin films flow sensors were fabricated by using aluminum oxide films as medium layer and their characteristics were investigated after annealing at 600 ℃ for 60min. Aluminum oxide improved adhesion of Pt thin films to SiO_(2) layer without any chemical reactions to Pt thin films under high annealing temperatures. Output voltages increased as gas flow rate and gas conductivity increased because heat loss of heater, which was integrated with a sensing resistor in the flow sensor, increased. Output voltage of flow sensor fabricated on membrane strucrure was 101mV at O_(2) flow rate of 2000sccm, heating power of 0.8W while flow sensor fabricated on Si substrate without membrane had output voltage of 78mV under the same conditions.

      • 인삼의 산지판별을 위한 전자코의 Conducting Polymer 센서와 Metal Oxide 센서의 이용

        노봉수,고재원,김상용 서울여자대학교 자연과학연구소 1997 자연과학연구논문집 Vol.9 No.-

        인삼의 원산지를 확인하기위하여 전자코를 사용하였다. 농산물에서 배출되는 가스성분을 아무런 전처리 과정 없이 coducting polymer센서와 metal oxide 센서를 각각 사용하였을 때와 동시에 함께 사용하였을 때 정준판별분석결과 두 가지 형태의 센서를 활용하였을 때 인삼의 산지를 뚜렷하게 판별할 수 있었다. The habitats of ginseng was investigated by using electronic nose without any pretreatment. Metal oxide sensor and conduction polymer sensor as a sensing material were used, respectively and also used both of them. The difference of Canonical discriminant scores in case of using both rather than one sensor was distinctly shown. The separation of Chinese ginseng and the locally produced one could be obtained by using composite sensing systems of electronic nose.

        사람 뇌척수액중 Transthyretin의 항산화작용

        양성렬,최기오,박종근,류문희,홍석노,김수한,안봉환,이제혁,이민화 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.4

        Protective effects of human cerebrospinal fluid antioxidants against enzyme inactivation caused by metal-catalyzed oxidation systems were investigated. When purified glutamine synthetase(GS) was incubated with human cerebrospinal fluid(CSF), the enzyme was progressively inactivated. Catalase and EDTA could inhibit the enzyme inactivation by 50-80%. Small-molecular(Mr< -10,000) fraction of CSF inactivated the exogenous GS, but large-molecular(Mr> -10,000) fraction did not. The GS inactivation by the small-molecular fraction was also markedly inhibited by catalase and EDTA. These results suggested that metal-catalyzed oxidation is involved in the GS inactivation by the small-molecular fraction of CSF. Dithiothreitol(DTT) was shown to inhibit almost completely the oxidative inactivation of GS by CSF. However, DTT inhibited only partially the oxidative inactivation of GS caused by small-molecular fraction of CSF. When large-molecular fraction of CSF was separated by anion-exchange HPLC chromatogrpahy, there was a peak of antioxidant activity inhibiting the small-molecular fraction-induced GS inactivation in the presence of DTT. The antioxidant activity was neutralized by monoclonal antibodies to transthyretin. Purified transthyretin was found to efficiently inhibit ascorbate/Cu^(2+)-induced GS inactivation in the presence of DTT. Uric acid and glucose did not show any protective effect on the GS inactivation in the same condition. The above results suggest that metal-catalyzed oxidation occurs normally in human CSF, and that transthyretin may play an important role as a CSF antioxidant in protecting proteins from metal-catalyzed oxidation.

      • 9/11 테러와 미국의 정보공동체 변화

        장노순,박수홍,조상태 한라대학교 2007 論文集 Vol.10 No.-

        The emergence and broad spread of transnational threats since the collapse of the Soviet Union have emphasized the need of efficient intelligence agencies as well as military forces as means of national security. The attack of September 11, 2001 upon the United States brought on a drastic transformation of its domestic security policy and governmental structure. This study is aimed at exploring how the 9/11 attack has influenced America's intelligence community and how such an intelligence failure has changed the security policy. One of the biggest reforms is to establish the National Security Agency (NSA) that is designed to control and coordinate all members of the intelligence community. However, the adaptation of America's intelligence community to the current security environment is not sufficient to maintain its leadership in the global society from new threats such as terrorists. Agents with skill of foreign languages and local informants will play a key role of collecting and analyzing information concerning the adversary.

      • 일렉트로크로믹 소자용 작용전극에 관한 연구

        정귀상,노상수 東西大學校 1999 동서논문집 Vol.5 No.-

        Tungsten oxide(WO₃) thin films were prepared by reactive magnetron sputtering in an Ar/0₂ atmosphere from a compressed powder WO₃ target and their electrochromic(EC) phenomena were investigated. PEO-LiClO₄- PC polymer electrolyte can easely be formed into thin films and showed high transmittance. Such electrolyte has electrochromic properties suitable for large-scale electrochromic devices.For the devices using WO3₃thin films of 1500,2500,4000Å thickness with glass/IT0/W0₃/PEO-LiClO₄-Pc/ITO/g1ass structure, an optical modulation of 50∼60% were obtained at a potential range of 1-2 V. It has shown tphat transmittance and reflectance of light could be electrically controlled by low applied voltage.

      • 담금 방법을 달리하여 제조한 고추장중 에탄올 및 미생물의 변화

        이택수,전명숙,박성오,노봉수 서울여자대학교 자연과학연구소 1996 자연과학연구논문집 Vol.7 No.-

        메주, 코오지, 아밀레이스, 프로테이스 등을 사용해서 담금방법을 달리하여 제조한 고추장중 미생물균수의 변화와 에탄올 생성을 관찰하였다. 가장 많은 미생물은 호기성 세균이었으며 총균수는 1.1X10-1.3X10CFU/g이었고 반면 혐기성 세규수는 7.4X10-1.7X10CFU/g이었다. 90일 숙성 후 곰팡이보다 효모가 많았으며 코오지로 만든 고추장의 경우 30일 지난 후 곰팡이의 수가 4.2X10로 최대치를 보인 반면 효소를 첨가한 구는 90일 지나서 최고치에 도달하였다. 효모수는 프로테이스를 첨가한 구가 90일 지나서 최고치에 도달하였다. 효모수는 프로테이스나 아밀레이스를 첨가한 고추장이 90일 후에 가장 많았으며 메주 고추장은 90일후 가장 적은 것으로 나타났다. 에탄올 생성은 효모수가 가장 많은 아밀레이스 고추장보다 코오지 고추장이 제일 많이 생성되었다.
