金萬善小說硏究 : 「洪水」와 「解防의 노래」를 중심으로 Focusing on ‘The Floods’and ‘The song of the Liberation’
朴丁奎 서울産業大學校 1995 논문집 Vol.41 No.1
In the periods of cataclysm, the Liberation and the Division, because of the problems of ideologies which important writers had chosen for himself, history of our literature remained damaged. After that the lifting of the ban on works of writers gone or kidnapped to North Korea has paved the way for the restoration of the damaged history of our literature. But this has not been completed yet. That's because varied studies on these writers were insufficient and it was impossible to define their rightful places in literary history. This thesis, in that respect, attemps to be a little help to the restoration of the damaged history of literature by examining the works of Kim Man-Sun, who has not been yet rediscovered, through new methodologies.First this thesis examines his life and literary activity and then his two works, ‘The Floods’and ‘The song of the Liberation’as a subject of study. The reason they are chosen is that each of them is representative of his works respectively in his early period and the later period directly after the Liberation when he wrote energetically. The methodology used in this analysis is time-plot analysis. As a result, ‘The floods’can be said to be catagorized in time sequence-novels and belong to relistic novels in the trend of literature, putting trust in the progress. In the case of ‘The Song of the Liberation. the writer's world-view is shown through the process of putting up Kim Byung-Hak, a conservative and reactionary, as a agent of focalization and satirizing and jeering ignorance and reactionary activities of comprodor capital forces represented by Kim Byung-Hak, against historical development, using irony. On this occasion the time-plot which runs against the time sequence contributes to revealing conserative-reactionary activies of focus-narrator, Kim Byung-Hak.

Wildfires destroy forests, a resource for mankind, and cause great damage to wild animals and plants. These wildfires are caused by weather conditions and human activities. Various researches are being conducted in each country to detect and effectively suppress wildfires. In this study, a machine learning model that can predict wildfires was proposed. In the study, the proposed model was validated using a reliable forest fire database. For verification, data set collection, data preprocessing, model training, and model testing were performed. ANN was used to create a forest fire prediction model. A website was built to predict wildfires and take quick action using the learned model. As a result of the experiment using the proposed model, it was confirmed that the accuracy was 87%. 산불은 인류의 자원인 산림을 파괴하고 야생 동식물에 많은 피해를 주고 있다. 이와 같은 산불은 기상 조건 및 인간의 활동에 의해서 발생하고 있다. 각 국가별로 산불을 감지하고 효율적으로 진압하기 위해서 다양한 연구를 진행하고 있다. 본 연구에서는 산불을 예측할 수 있는 머신 러닝 모델을 제안하였다. 연구에서는 신뢰할 수 있는 산불 데이터베이스를 사용하여 제안하는 모델을 검증하였다. 검증을 위해서 데이터 세트 수집, 데이터 전 처리, 모델 학습, 모델 테스트 등을 수행하였다. 산불 예측 모델을 만들기 위해서 ANN을 활용하였다. 학습한 모 델을 이용하여 산불을 예측하고 빠른 조치를 하기 위해서 웹 사이트를 구축하였다. 제안하는 모델을 이용하여 실 험한 결과 87%의 정확도를 보이는 것을 확인하였다.

In this paper, we developed the proximity exposure system with the vertical structure of glass and mask stage to minimize the mask's warp caused by the pull of gravity. This system, which canirradiate the ultra violet through 1440 H 850 $\textrm{mm}^2$ and 1330X 1015 $\textrm{mm}^2$ exposure area, has the followingcharacteristics. The glass stage can be inclined by 80 degrees at vertical structure to load substrate withsafety on it. When the glass stage is the vertical state, the gap control, alignment control and exposureof ultra violet are executed. So, it enhances the pattern uniformity by minimizing the mask's warp. Theglass stage can also control the gap between the mask and the substrate by the coarse and fine motioncontrol. The mask stage can adjust the posture of photomask to the position of substrate by imageprecessing method. The galss stage for the gap control and the mask stage for the alignment aredesigned independently for each function.
Thermal transport in thorium dioxide

In this research paper, the thermal transport in thorium dioxide is investigated by using nonequilibriummolecular dynamics. The thermal conductivity of bulk thorium dioxide was measured to be 20.8 W/m-K,confirming reported values, and the phonon mean free path was estimated to be between 7 and 8.5 nmat 300 K. It was observed that the thermal conductivity of thorium dioxide shows a strong dependencyon temperature; the highest thermal conductivity was estimated to be 77.3 W/m-K at 100 K, and thelowest thermal conductivity was estimated to be 4.3 W/m-K at 1200 K. In addition, by simulatingthorium dioxide structures with different lengths at different temperatures, it was identified that shortwavelength phonons dominate thermal transport in thorium dioxide at high temperatures, resulting indecreased intrinsic phonon mean free paths and minimal effect of boundary scattering while

A Laser Doppler Velocimetry was applied to meadure the turbulence within the engine cylinder. In this study, the variation of turbulence with respect to time and space was analyzed and discussed. The main velocity was obtained from low-pass filter output and the turbulence intensity was obtained from high-pass filter output. The effect of cut-off frequency was investigated for the turbulence analysis. Also, the effect of cycle variation, average velocity, squish and swirl on the turbulence intensity were investigated.
