조영수,장건익,Cho, Youngsoo,Jang, Guneik 한국결정성장학회 2021 한국결정성장학회지 Vol.31 No.4

상온에서 PET 기판 위에 Mn-SnO₂/Ag/Mn-SnO₂ 3중 다층막을 RF/DC 마그네트론 스파터링 방식으로 제조하였다. EMP 시뮬레이션 결과에 따라 Mn-SnO₂의 막 두께는 40 nm, Ag 막 두께는 13 nm로 고정하였다. 550 nm 파장대역에서 측정한 3중막의 투과율은 82.9에서 88.1 % 범위였으며 면저항은 5.9에서 6.9 Ω/☐로 변화하였다. 가장 높은 성능지수(ϕ_TC)는 48.1 × 10^-3 Ω^-1로 나타났다. 곡률반경 4, 5 mm 조건에서 inner 밴딩과 out 밴딩의 굽힘시험을 10,000회 실시한 결과 Mn-SnO₂/Ag/Mn-SnO₂ 3중막의 저항변화율은 약 1.5 %로 탁월한 기계적 유연성을 보였다. Typical Mn-SnO₂/Ag/Mn-SnO₂ tri-layer films were prepared on a PET substrate by RF/DC magnetron sputtering method at room temperature. Based on EMP simulation, the thicknesses of the top and bottom Mn-doped SnO₂ layers were kept at 40 nm and the Ag layer was maintained at 13 nm for continuous electrical conduction. The experimentally measured optical transmittances at 550 nm wavelength were ranged from 82.9 to 88.1 % and sheet resistances were varied from 5.9 to 6.9 Ω/☐. The highest value of figure of merit, ϕ_TC was 48.1 × 10^-3 Ω^-1. Based on bending test under 4 and 5 mm of inner and outer curvature radius condition, tri-layer film resistance varies only by approximately 1.5 % after 10,000 bending cycles, showing excellent mechanical flexibility.

본 고에서는 텔레매틱스/LBS용 실내외 연속측위를 위해 무선통신 기반 실내측위 및실외측위 기술에 대하여 동향을 분석한다. 위치기반서비스에서 측위기술은 핵심.기반기술로 오늘날 GPS가 그 중심을 차지하고 있지만 실내와 같은 음영지역에서는 새로운방식의 측위기술을 필요로 하고 있으며, 무선통신 인프라 기반의 측위 기술이 연구되어 오고 있다. 실외에서는 CDMA 기반 무선측위 기술, 실내에서는 WLAN, UWB, 적외선, 초음파, RFID 등의 인프라를 이용한 무선측위 기술이 연구되고 부분적으로 상용화되고 있다. 그러나 아직 실내외 연속측위를 위한 기술은 개념적으로 설계만 되고 있으며 상용화를 위한 기반기술이 연구중에 있다. 본 고에서는 실내외 연속측위를 위해 실내측위와 실외측위로 나누어 각각의 기술 동향을 분석하고 이 기술을 구현하기 위한 무선측위 기술을 분류, 설명한다.

한국어, 독일어, 영어에 나타난 색깔의 상징의미(II) - 빨강, 노랑, 초록 -

조영수,Cho Young-Soo 한국독어학회 2003 독어학 Vol.8 No.-

In dieser Arbeit wird versucht, einen weiteren theoretischen Rahmen $f\"{u}r$ die Farbensymbole(Rot, Gelb und Grun) in der deutschen, englischen und korearischen Sprache, vor allem in Idiomatik weiterzuentwickeln. Rot und Grun sind in diesen Sprachen reichlicher als Gelb vertreten. Die symbolische Bedeutung von Rot ist besonders ambivalent Es ist die Farbe der Gesundheit, aber auch die Farbe des Blutes, Krieges und Todes. Rot ist in den untersuchten Sprachen als 'sehr', 'gut', 'gesund' oder 'schlecht' belegt Rot zeigt aber einzelsprachliche Eigenschaften. Im Koreanischen ist Rot syrnbollisch mit 'Frau', im Englischen mit $'B\"{u}rokratismus'$ verbunden.. Gelb hat auch $widerspr\"{u}chliche$ Symbolbedeutung .Es ist die Farbe der $Fr\'{u}hlingsblumen$, der Sonne und des Lichtes. Aber Gelb kann die Farbe von 'Neid, Eifersucht' oder 'feige, schlecht' sein. Grun ist die wichtigste Farbe der Natur. So ist diese Farbe symbolisch mit 'gut', 'unreif, 'sehr, viel', 'Wachstum und Gedeihen' assozziert. Durch Vergleich und Analyse der Farbensymbole in diesen drei Sprachen und durch Resultat der Antwort auf Fragenbogen an denen 99 Deutschen, 100 Amerikaner und 101 Koreaner teilnahmen, zeichnen sich folgende Ergebnisse ab. Sprachsymbole von dieser Farbe hat auf die Farbenwahrnehmungen von diesen Leuten nicht direkte $Einfl\"{u}sse{\;} ausge\"{u}bt$. Rot assoziert in 89 Koreanern und 5 Amerikanern 'Leidenschaft': Gelb in 52 Amerikanem, 47 Deutschen und 38 Koreanern $'W\"{a}rme'$: Grun in 33 Amerikanern, '37 Deutschen und 11 Koreanern 'Frieden'. Im Englischen und Deutschen zeigt sich die Assoziation von Gelb mit 'Neid, Eifersucht', was mit kulturellen Vorstellungen $\"{u}bereinstimmt$. 38 Deutsche und 4 Amerikaner geben $f\"{u}r$ Gelb die Symbolbedeutung 'Neid' an. Hier bin ich mit sprachlichem Determinismus von Wharf-Hypothese einverstanden: Verschiroene Sprachgemeinschaften erfassen die Wirklichkeit in ganz verschiedener Weise. Sprachsymbol und Kul­tursymbol scheinen an die Farbenwahrnehmungen von untersuchten Leuten $anzukn\"{u}pfen$.

Succinylation이 葉濃縮蛋白質의 機能性에 미치는 影響

조영수(Yeong Su Cho),김종규(Jong Kyu Kim) 한국식품영양과학회 1983 한국식품영양과학회지 Vol.12 No.3

葉濃縮蛋白質(LPC)을 이용해서 人工乳를 만들 수 있는 기틀을 마련코저, 葉濃縮蛋白質의 機能的 性質을 milk casein 수준으로 높이기 위해 섬바디(Dystaenia takeshimana Nakai) 잎에서 추출한 chloroplastic protein과 cytoplasmic protein 및 Italian ryegrass(Lolium multiflorum Lamb.)에서 抽出한 葉濃縮蛋白質 1g당 succinic anhydride 0. 10, 0. 25, 100g씩을 加해 숙시닐화시켜 기능성을 조사한 결과는 다음과 같다.<br/> 1. bulk density는 섬바디잎에서 추출한 chloroplastic protein 및 cytoplasmic protein과 Italian ryegrass에서 추출한 LPC가 succinic anhydride의 무처리구에서 높았으며 숙시닐화 시킴으로 감소한 후 숙시닐화가 증가하므로서 bulk density는 어느 정도 증가하는 추세였다.<br/> 2. 용해도는 숙시닐화를 시킨 각 구에서는 Italian ryegrass LPC 1g에 succinic anhydride 1g 첨가반응시 섬바디 chloroplastic protein에서는 시료 1g당 succinic anhydride 0.1g이상 첨가반응시 milk casein 보다 용해도가 높은 경향이었다.<br/> 3. 흡수도 및 지방흡착에서는 숙시닐화 시킨 것과 시키지 않은 것 모두가 milk casein 보다 높은 경향이었다.<br/> 4. 유화능과 유제의 안정성에서는 숙시닐화를 시키지 않은 各 LPC가 약간 낮은 반면 숙시닐화 시킴에 따라 milk casein 보다도 높고 점점 증가하는 경향이었다. This experiment was carried out to investigate the capability of production of artificial milk for leaf protein concentrate (LPC). Chloroplastic protein and cytoplasmic protein were extracted from leaves of Dystaenia takeshimana Nakai and LPC was extracted from leaves of Italian ryegrass to increase the functional properties of LPC as a level of milk casein.<br/> One gram of chloroplastic protein and cytoplasmic protein and Ig of LPC were succinylated by addition of succinic anhydride 0.1, 0.25, and lg respectively. Their functional properties were inves tigated in this experiment.<br/> The results obtained were summarized as follows:<br/> 1. The non-succinylated LPC showed a higher value in bulk density than the chloroplastic protein, the cytoplasmic protein and LPC succinylated by addition of succinic anhydride 0.1, 0.25, and lg respectively. Nevertheless, succinylation had an enhancing effect as indicated by the rises as the degrees of succinylation was increased.<br/> 2. Although solubility of non-succinylated LPC was lower than that of milk casein, succinylation caused an effective increase in the solubili ty of the protein and LPC.<br/> 3. Water absorption and fat absorption of succinylated LPC were twice to eight times higher than those of milk casein. Fat absorption was not influenced to the extent by succinylation as the water absorption. Excessive succinylation resulted in the decrease of both water absorption and fat absorption.<br/> 4. Emulsifying activity and emulsion stability were increased in proportion to the succinylated degree of LPC. More than 10% increase in the amount of succinic anhydride resulted in an apparent increase in emulsifying activity and emulsion stability. Besides, the succinylated LPC showed more excellent functional properties in emulsifying activity and emulsion stability than milk.

Orotic acid 투여가 흰쥐의 혈청 , 간장 및 신장 지질 농도에 미치는 영향

조영수(Young Su Cho),김석환(Seok Hwan Kim),차재영(Jae Young Cha) 한국응용생명화학회 1996 Applied Biological Chemistry (Appl Biol Chem) Vol.39 No.3

It was generally known that over-ingestion of dietary orotic acid caused hepatic disorder by the lesion of fatty acid and cholesterol synthesis in rats. The present study was carried out to investigate the effects of dietary orotic acid on the Lipid composition of semen, liver and kidney of rats. For the experiments, rats were fed with commercialized chow powder diet in the presence or absence of 1% orotic acid. The prepared diets were fed to male rats (Sprague-Dawley strain, 90∼100 g of body weight) for 21 days. According to the results, orotic acid treated group showed that each concentration of serum cholesterol, triglyceride and phospholipid was significantly decreased (p$lt;0.05). The centration of liver triglyceride was significantly decreased (p$lt;0.05). In the presence of 1% orotic acid, the weight of liver increased while that of kidney decreased. The treatment of orotic acid seemed to have no effects on the phospholipid composition in liver and kidney, except the Kidney lysophosphatidylcholine. In the comparison of the phospholipid composition between liver and kidney. the leves of sphingomyeline and phosphtidylethanolamine in the kidney were higher than those in the liver. Among the composition of fatty acid in kidney, the concentration of linoleic acid (18:2) was increased, and the concentration of arachidonic acid (20:4) was decreased with the addition of the orotic acid.
