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.

하악이부와 두개안면골격의 상관성에 관한 측모두부방사선 계측학적 연구

노상호,이기수 慶熙大學校 齒科大學 1995 慶熙齒大論文集 Vol.17 No.2

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.

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.

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.

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.

이상훈,노연희,한중수,고재경 한양대학교 의과대학 1993 한양의대 학술지 Vol.13 No.1

G proteins, a family of guanine nucleotide-binding protein superfamily, are involved in transmembrane signaling systems as transducers. In this study cDNAs encoding αsubunit of the stimulatory G protein (G α ) from rabbit liver were cloned and their nucleotide sequences were determined : a λgt 11 cDNA library from total cellular poly (A)' mRNA in rabbit liber was screened for recombinant λDNA that codes for G α with labeled probe. The probe used was an EcoRI digested 3' end fragment of cDNA for G α from olfactory neuroepithelium of rat. Six of the approximately recombinant clones were screened by in situ hybridization and by autoradiography, detecting sixteen positive clones. These clones were tested using polymerase chain reaction (PCR) technique and thirteen of them were turned out to have two sets of conserved sequence in αcDNA. Four clonse among them were selected form analysis of their cDNA sequences, showing the presence of two types of cDNA, namely and with the total length of nucleotide sequence of1.392bp and 1.613bp, respectively . From nucleotide sequence analysis the amino acid residues of -1 and α-2 were deduced : they contain 335 and 386 amino acid residues (including the initiator methionine), respectively. The calculated molecular weights for and were 38.9kd and 44.6kd, respectively. The significant difference in size between two cDNAs for G αseemed to be due to the assumption that alternative promoter and leading exon might be involved in transcribing the mRNA for . Two types of cDNA from rabbit liver shared over 95% of amino acid homology with that from rat olfactory neuroepichelium if deleted portions are not counted. More information on the cDNAs could be obtained through further studies such as Sl nuclease protection experiment, expression and mutation study.

마그네트론 코스퍼터링에 의한 측온저항체 온도센서용 Pt-Co 합금박막의 증착과 그 특성

정귀상,김서연,노상수 東西大學校 1997 동서논문집 Vol.3 No.1

Plantinum-Cobalt alloy thin films were deposited on Al₂O₃ substrate by cosputtering for RTD(Resistance Thermometer Devices) temperature sensors. We made Pt-Co alloy resistance patterns on the Al₂O₃substrate by lift-off method and investigated the physical and electrical characteristics of these films under various conditions, the input power, working vacuum, annealing temperature and time, and also after annealing these films. The resistivity and sheet resistivity of these films were decreased with increasing the annealing temperature. After the annealing treatment at 800℃ for 60 min, the resistivity and sheet resistivity of Pt-Co thin films was 15μΩ·cm and 0.5Ω/□, respectively and the TCR value of Pt-Co alloy thin films with thickness of 3000Å was 3740 ppm/℃ in the temperature range of 25∼400℃. These results indicate that Pt-Co alloy thin films have potentiality for the RTD temperature sensors.
