김기현(Kim, Ki-Hyun),안세진(Ahn, Se-Jin),전영갑(Chun, Young-Gab),박병옥(Park, Byun-Ok),윤경훈(Yoon, Kyung-Hoon) 한국신재생에너지학회 2005 한국신재생에너지학회 학술대회논문집 Vol.2005 No.06

나노 입자 분무 기법을 이용한 Cu(In,;Ga)Se₂ (CIGS) 광흡수층 제조 기법은 고진공 장치를 사용하지 않는다는 점에서 대면적 저가형 CIGS 태양전지 양산에 적합한 차세대 기술로 인식되고 있다. 그러나 일반적으로 스프레이 된 상태의 CIGS충 자체는 태양전지 제조에 적합하지 않은데 이는 스프레이 막의 다공성 구조 때문이다. 본 연구에서는 나노입자 분무 기법을 이용하여 증착한 CIGS 광흡수층막을 질소 또는 셀레늄 분위기에서 열처리함으로써 태양전지 제조에 적합한 치밀한 구조의 CIGS 광흡수충을 제조하고자 하였다. 실험 결과, 질소 분위기 500?C의 온도에서 1시간 열처리하여도 CIGS 나노 입자의 성장은 거의 일어나지 않는 것으로 나타났다. 반면 셀레늄 분위기 500?C의 온도에서 30분 열처리시 입자 크기가 1{mu}m이상인 치밀한 광흡수층을 얻을 수 있었다. 본 결과는 CIGS 나노 입자의 입자 성장 반응에서 열에너지 단독에 의한 표면 에너지 감소 효과는 미미하며 셀레늄 증기의 역할이 더욱 크다는 것을 의미하는 것이다.

튀김할 때 식용유는 가열매체인 동시에 풍미나 영양원이 된다. 튀김용 식용유의 품질변화방지를 위한 기초자료를 얻을 목적으로 식용대두유로서 고온처리 및 튀김을 할 때 BHA, TBHQ, silicone 및 시트르산 첨가가 식용유의 품질에 미치는 영향을 실험하였다. 98℃이하의 열처리 결과 시트르산 1ppm, TBHQ는 50∼200ppm첨가한 것이 산화방지에 효과적이었으나 BHA와 silicone은 효과가 거의 없었다. 180℃ 가열처리 및 튀김시험에 있어서는 시트르산은 산화를 촉진하는 경향이 있었고 BHA 및 TBHQ는 별 효과가 없었으며 silicone이 가장 효과가 좋았다. silicone 1∼5ppm가지는 품질변화방지효과에 큰 차이가 없었으나 튀김할 때는 원료에 이행하는 양이 있으므로 첨가량이 증가할수록 효과가 좋았다. 그러므로 식용유 품질변화를 방지하는데 있어 100℃이하에서 처리할 때는 시트르산을 첨가하는 것이 효과적이고, 튀김처럼 고온처리하는 식용유에서는 1∼5ppm의 silicone을 첨가하는 것이 효과적이라는 결론을 얻었다. Edible oils serve both as a heat transfer medium and a source of flavor and nutrition since ,some of the fat is absorbed by the food being fried. In this paper, the effects of butyl hydroxyanisole(BHA), teritary butyl hydroquinone(TBHQ), silicone and citric acid on thermal stability of the soybean oil during heating and frying were evaluated. Judging from the results of swift stability test (active oxygen method) that the minimum effective concentration of citric acid and TBHQ for ,the thermal stability of soybean oil when heated at 98℃ was 1 ppm and 50 to 200 ppm, respectively. But BHA and silicone showed no effect. On the other hand, silicone seemed to improve the thermal stability of soybean oil during heating at 180℃ or frying with potato while BHA and TBHQ showed no significant effect.

Sound is the sensation produced when longitudinal variations of molecules in the external environment. ie, altenate phases of condensation and rarefaction of the molecules, strike the tympanic membrane. The purpose of speaking is communication between humans. It is very important for social life to speak and hear exactly. It there were problems to speak, it is very unconvenient for social life psychologically. The purpose of this experiment was to analyse the frequency and duration of pronunciation. Each 20 male and female who were living in Seoul and speaking standard Korean, had participated in this experiment. Each 10 male and female, who were wearing dentures and adapted at least over 1 years, had participated in this experiment also. The data were taken and analysed by Philips PM 3350A Storage Oscilloscope which had 68008 up microprocessor IEEE-488 interface. The results were as follows 1. High pitches were appeared in early stage of pronunciation in plosive sounds(ㅂ, ㅋ, ㅌ, ㅍ)and Y system vowel diphthorgs. 2. Condensation waves were seen in later stage of pronunciation in frictional sounds(ㅅ,ㅎ) and nasal sound(ㄴ, ㅁ). 3. the average data of frequency and duration were as follows ◁ 표 삽입 ▷ (원문을 참조하세요) 4. There were special pitches such as 111, 181, 200, 250, 333, 400, 500, 1000, 2000 Hz in all subjects

Carbon monoxide is generated from the incomplete combustion of carbon-containing materials. Carbon monoxide cause muscle necrosis leading to myoglobinuria and acute renal failure. The hyperbaric oxygen exposure is increased production of active free radicals. Free radicals which promoted peroxidation of unsaturated fatty acids may destroy essential cellular components and itself cytotoxic materials. Superoxide dismutase, one of the protective mechanisms against tissue damage, catalyzed the dismutation of superoxide anion to less toxic product. The author performs the present study to investigate on Mn-SOD and Cu, Zn-SOD immunoreactivities in kidney and heart carbon monoxide (CO) and hyperbaric oxygen (HBO) exposure. The animals were divided CO exposure group, air release after CO exposure group, HBO exposure group and, CO and HBO exposure group. The specimen were sectioned in 16㎛ with cryostate. The Mn-SOD and CuZn-SOD immunohistochemistry was performed in renal corpuscle, proximal and distal convoluted tubules of kidney and, in sarcoplasm and sarcolemma of heart muscle. The results obtained were as follows: 1. The immunoreactivity of Mn-SOD were increased in renal corpuscles and distal convoluted tubules, were similar to control group in proximal convoluted tubules. 2. The immunoreactivity of Cu, Zn-SOD were increased than that of control group in renal corpuscles and distal convoluted tubules, were same that of the control group in proximal convouted tubules. 3. The immunoreactivity of Mn-SOD were increased at all experimental group of sarcoplasms of heart muscle. 4. The immunoreactivity of Cu,Zn-SOD were increased than that of control group in sarcolemma of heart muscle. These results suggest that the immunoreactivity of SOD after CO or HBO exposure is greatly increased in kidney and heart.

김세열,정천석 울산대학교 1998 공학연구논문집 Vol.29 No.2

고유전율의 유전체 세라믹 기판을 사용하여 GPS(Global Positioning System) 위성수신용 단일 급전 원형편파 마이크로스트립 패치 안테나를 제작하여 시험하였다. 제작된 안테나는 작기 때문에 차량과 같은 이동체에 사용하기 적합하였다. 우선회 원형편파를 구현하기위해 정방형 패 치면의 모서리를 잘랐다. 급전 방식은 패치면의 50Ω지점에 동축 프로브로 하였고, 시뮬레이션 하여 1.57542GHz에서 공진되도록 설계하였다. 제작된 안테나의 반사손실은 -13.394dB이고, 공진 주파수는 설계 주파수보다 약간 높은 1.591GHz로 측정되었다. 따라서 이 안테나는 GPS 위성수신용으로 사용하기에 적합하였다. Single-feed circularly polarized microstip patch antenna for GPS Satellite Receiver was fabricated by using high permittivity dielectric ceramic substrate and tested. This miniature antenna is suitable to be used for mobile such as cars. By truncating the corners of squared patch, right hand circular polarization was realized. It was fed by coaxial probe on patch at 50Ω impedance, and was simulated to resonate at 1.57542GHz. The return loss of this antenna was -13.394dB, and resonant frequency was measured at 1.591GHz higher than desired frequency. Therefore, it could be used for GPS Satellite Receiver.

An experimental study on the preparation of monolithic porous polymers by environmentally friend process in supercritical carbon dioxide has been carried out. Polymerization mixture composed of a cross-linking monomer, initiator and functional co-polymer was charged in the reactor with sapphire window. After the system was purged with a flow of CO₂ for 15 min, the reactor was pressurized with liquid CO₂ up to 100 bars. The reactor was isolated from and placed back to the system via quick connector for shaking until the mixture had become fully homogeneous. The reactor was then heated and pressurized to the required reaction conditions and left overnight. After cooling and CO₂ evacuation, the polymer was removed from the reactor as dry, white, continuous monoliths. The effect of experimental conditions on the physical properties of porous polymer was systematically examined, and it was found that monomer content had a major effect on the physical properties of the polymers.

Ion exchange of Na­fluor­tetrasilicic Mica (Na­TSM) by univalent cations of Li^+, K^-, and bivalent cations of Mg^2+, Ca^2+, Ba^2+, was studied to investigate the fundamental properties of cation exchangability of it. The absorbed equivalents of the alkali and alkali earth metal ions were smaller than Na^2+ ion equivalents dissolved from the Na­TSM. The difference of their ion exchange capacities was changed by the kind and concentration of the cations and was considered that H^+ ions from the dissociation of water were absorbed in the surface of the Na­TSM. H^+ ion and cation exchange capacities were about 80% of the interlayer Na^+ ion in the Na­TSM, and it was considered in terms of the particle size and the drying condition of the starting material.
