잉크젯 헤드의 발열체에 적용하기 위해 poly-Si/Sio_2/si 의 다층기판 위에 결정화된 안정한 CoSi_2 코발트실리사이드 박막을 증착하여 발열체를 제작하고 이들 발열체의 구조적 형상과 온도저항계수 등 전기적 특성을 조사하였다. CoSi_2 코발트실리사이드 박막의 형성은 금속 Co 박막을 급속 열처리장치를 이용하여 800℃에서 20초 동안 질소 분위기에서 열처리하여 실리사이드 박막을 형성하였다. 발열체의 온도정항계수값은 약 0.0014/℃ 값을 얻을 수 있었다. 인가전압 10v,주파수 10kHz 및 펄스 간격 1 ㎲ 인가시 발열체의 순간전력은 최대 2 watt를 나타내었다.

PREDICTION OF SEVERE ACCIDENT OCCURRENCE TIME USING SUPPORT VECTOR MACHINES
김승근,노영규,성풍현 한국원자력학회 2015 Nuclear Engineering and Technology Vol.47 No.1
If a transient occurs in a nuclear power plant (NPP), operators will try to protect the NPP byestimating the kind of abnormality and mitigating it based on recommended procedures. Similarly, operators take actions based on severe accident management guidelines whenthere is the possibility of a severe accident occurrence in an NPP. In any such situation,information about the occurrence time of severe accident-related events can be veryimportant to operators to set up severe accident management strategies. Therefore, supportsystems that can quickly provide this kind of information will be very useful whenoperators try to manage severe accidents. In this research, the occurrence times of severalevents that could happen during a severe accident were predicted using support vectormachines with short time variations of plant status variables inputs. For the preliminarystep, the break location and size of a loss of coolant accident (LOCA) were identified. Training and testing data sets were obtained using the MAAP5 code. The results show thatthe proposed algorithm can correctly classify the break location of the LOCA and can estimatethe break size of the LOCA very accurately. In addition, the occurrence times ofsevere accident major events were predicted under various severe accident paths, withreasonable error. With these results, it is expected that it will be possible to apply theproposed algorithm to real NPPs because the algorithm uses only the early phase data afterthe reactor SCRAM, which can be obtained accurately for accident simulations

The crystallized stable cobalt silicide$(CoSi_2)$ films were prepared on $poly-Si/SiO_2/Si$substrates for the application of inkjet printing head as a heating element with omega shape. The structural images and temperature resistance coefficient were investigated. The value of temperature resistance coefficient of the heating element was found to be about $0.0014/^{\circ}C$. The maximum power of the heating element was 2 W at the applied voltage of 2 V, 10 kHz in frequency and $1{\mu}s$ in pulse width. From the investigation of fatigue property according to the repeated applied voltages, there was no drastic changes in the resistances of heating element under the condition of $10^8$ pulsed cycles at below 15 V biased voltage. In contrast, the resistance of heating element was greatly increased at $10^6$ pulsed cycles when the heating element was operated at 17 V. 잉크젯 헤드의 발열체에 적용하기 위해 $poly-Si/SiO_2/Si$ 다층기판 위에 결정화된 안정한 코발트실리사이드$(CoSi_2)$ 박막을 형성하여 오메가 형태의 발열체를 제작하고 발열체의 구조적 형상과 온도저항계수 등 전기적 특성을 조사, 연구하였다 $(CoSi_2)$ 박막의 형성은 금속 Co 박막을 급속 열처리장치를 이용하여 $800^{\circ}C$에서 20초 동안 질소 분위기에서 열처리하여 실리사이드 박막을 형성하였다. 발열체의 온도 저항계수 값은 약 $0.0014/^{\circ}C$ 값을 얻을 수 있었다. 인가전압 10 V, 주파수 10KHz 및 펄스간격 $1{\mu}s$ 인가시 발열체의 순간전력은 최대 2W를 나타내었다. 반복된 전압인가에 따른 발열체의 피로특성을 조사한 결과 15 V 이하의 전압인가시 $10^8$ 펄스 cycle 까지 저항변화가 거의 없었으나 17 V 인가전압에서는 $10^6$ cycle에서 발열체의 저항이 급격히 증가하였다.

洪淳馨,盧永圭 부산대학교 과학교육연구소 1985 교사교육연구 Vol.11 No.-
Author has investigated on the charcter of plant community which was carried out extending several times from 1982 to 1984. The results can be summuarized as follows: 1. All vascular plants in Sang-Kye-Sa area consisted of 78 families, 236 genera, 280 species, 47 varieties, 1 forme. There are 131 species of woody plants and 197 species of herbaceous plants among 328 kinds. 2. Judging from spectrum by Raunkiaer, Sang-kye-Sa area belong to the southern part of the temperate regions which is high in the formation rate of phanerophytes. 3. This region is located in the southeast slope of Mt. Ji-Ri, so the annual precipitation is prevalent. And there is In the comfortable condition of plant growth because the annual average of temperature is also high in winter. 4. At the foot of mountains in less than 500m above sea level, dominant species were found Pinus densiflora, Carpinus laxiflora, Quercus variabilis and so on. 5. At 500-1,000m above sea level, dominant species were found Stewartia Koreana, Betula costata, Quercus variabilis, Carpinus laxiflora and so on. 6. Dominant species were found Quercus dentata, Betula ermani, Stewartia Koreana at 1,000-1,350m above sea level. 7. The plant community of Quercus mongolica was found at ridge line of mountains in more than 1,000m above sea level.
