The major GreenHouse Gas(GHG) exhausted from vehicles are CO₂, CH₄, N₂O. emission is mostly CO₂. but, according to global warming potential, CH₄is 21 times, N₂O is 310 times worse than CO₂. To reduce the Greenhouse gases(GHG) emission, we must need to develop Non-CO₂emission factor. For more detailed emission development we need a level of Tier3 emission factor development that are reflected in Domestic Vehicles emissions control technology. In this Study, it would be used as a basic reference for establishing GHG Reduction policy through developing Non-CO₂ emission factor of Tier3 level about domestic Vehicles.

본 연구에서는 페로망간 제조공정에서 발생한 집진분의 황산침출에 대하여 조사하였다. 황산의 농도, 반응온도, 교반속도, 입자크기 및 고-액비가 집진분 중의 Mn과 Fe의 침출에 미치는 영향에 대하여 검토하였다. Mn과 Fe의 침출속도는 황산의 농도가 높고 반응온도가 높을수록 높아졌다. 실험결과를 입자수축모델을 이용하여 검토한 결과 침출반응은 입자표면에서의 화학반응에 의해서 율속되는 것으로 생각된다. Mn과 Fe 침출반응의 활성화에너지는 각각 79.55 kJ/mol과 77.48 kJ/mol로 계산되었다. The sulfuric acid leaching of ferromanganese dust was studied. The effect of acid concentration, reaction temperature, stirring rate, particle size and solid to liquid ratio on Mn and Fe extraction in the solution were investigated. It was found that the leaching rate of Mn and Fe increased with increasing reaction temperature and sulfuric acid concentration. Examination of data by shrinking core model suggested that the leaching rate is controlled by chemical reaction at the surface of particle. The activation energy for the leaching reaction of Mn and Fe were calculated to be 79.55 kJ/mol and 77.48 kJ/mol, respectively.

The circular and flat heat pipe were experimentally investigated by using neutron imaging technique. This experimental study was performed at the DINGO of OPAL research reactor, Australia. The diameter of the circular heat pipe is 10 mm and the dimension of flat is 10(width) × 3(thickness) mm2, respectively. We used the distilled water as a coolant. The coolant distributions and 2-phase flow patterns were measured under heating conditions. Experimental results show that neutron imaging technique is a good tool to visualize the 2-phase flow and phenomena in the heat pipe. The coolant distributions and 2-phase flow patterns depend on installation posture of the heat pipe and volume ratio of the coolant. Finally, it was discussed to calculate the void fraction by neutron imaging technique.

Generally, human eye blinks are closely associated with the cognitive state or visual attention such as attentional requirements on visual stimuli. These previous studies have reported that eye blinks are related to explicit visual attention using blink rate, pattern and blink timing across subjects. However, these results have been obtained in a well-controlled experimental settings. So, it would prove difficult to investigate human's natural response in a continuous and realistic situation. In our study, we measured the eye blink intervals while participants viewed a movie clip. And we analyzed the blink interval data for relationship between visual attention and eye blink intervals. 24 participants took part in two experimental sessions, first session to measure the IEBI while viewing the movie clip and second session to conduct a memory performance test using a self-questionnaire, which were spaced 3 weeks apart. The results indicate significantly higher memory performance at long IEBI period than short IEBI period while watching a movie clip(t = 3.257, df = 17, p < 0.005, 2-tailed). In addition, memory performance score significantly correlated with the IEBI value(spearman's rho = 0.40, N = 36, p < 0.01, 2-tailed). Our results suggest that IEBI is used to measure or assess visual attention while wiewing the movie that it is capable of simulating aspects of real-life experiences by visual attention. Thus, we expect IEBI to be used to measure or assess our visual attention, cognition, further emotion about not only movies, advertisements and other cultural contents but also cognitive science.
