산업혁명 이후 가장 많이 사용되고 있는 에너지인 화석연 료를 통해 생활의 편의를 얻었지만, 주 연료인 석유는 약 40 년, 석탄은 약 220년, 가스는 약 60년 후에 고갈될 것이라 예 상된다. 또한 화석연료의 연소 배출물은 미세먼지를 포함 한 대기 오염을 일으키고 지구 온난화를 가속하는 주 원인이 기도 하다. 이러한 화석 에너지의 고갈에 대비하고 지구 환 경을 보존하기 위해 신 재생 에너지에 대한 기술적 요구가 증가하고 있으며, 이 중 수력, 지열, 풍력, 조력, 태양열과 같 이 탄소를 배출하지 않는 대체 에너지원 중 태양 에너지는 공해를 일으키지 않으면서 무한대의 자원으로 사용이 가능 하여 그 발전성이 기대되고 있다. 태양 에너지는 여러 가지 형태의 에너지로 변환되어 에너지원으로 사용이 가능한데, Emitter Electrode Design to Optimize the Optical and Electrical Characteristics of Planar Solar Cells
虽然通过产业革命后使用最多的能源——化石燃料获得了生活的便利，但据预测，主要燃料——石油、煤炭和天然气将分别在40年、220年和60年后枯竭。另外，化石燃料的燃烧排放物会引起包括浮尘在内的大气污染，也是加速地球变暖的主要原因。针对这些化石能源的枯竭,为了保存地球环境,对新能源和可再生能源技术的要求正在增加,其中水力、地热、风力,潮汐,不像太阳能和碳排放的替代能源中,太阳能源的不引起公害,无限的资源,可以用,发展他很期待着。太阳能可转换成多种形式的能源，可作为能源使用:Emitter Electrode Design to Optimize the Optical and Electrical Characteristics of Planar Solar Cells

In this article, we suggest a new method for measuring an aerosol’s extinction coefficient using a commercial camera. For a given image, we choose three pixel-points that are imaged for the same kinds of objects located in similar directions. We suggest and calculate aerosol extinction coefficients from these RGB gray levels and the different distances of the three objects. To compare our measurement results, we also measure extinction coefficients using lidar. Finally, we find that there are meaningful and sensible correlations between these two measurements, with a correlation coefficient of 0.86. We measure the aerosol extinction coefficient at three different RGB wavelengths using the same method. From these aerosol extinction coefficients at three different wavelengths, we find that the Angstrom exponent ranges from 0.7 to 1.6 over a full daytime period. We believe that these Angstrom exponents can give important information about the size of the fine particles.

Kum-Ho Kim, Sung‐Chan Park
In this study, we present methods to quantitatively analyze and correct the distortions and biocular parallaxes in a head-up display (HUD). To analyze asymmetrical distortions, five kinds of distortions are proposed and evaluated at five eye positions of an eyebox. The differences between distortions evaluated at the four corners of the eyebox and that at the center are defined as the relative distortions, which occur due to head motion of the driver. We also define the convergence and divergence parallaxes at six biocular positions in the eyebox to quantitatively analyze them. Using these analytical methods, we constrain the degree of biocular parallaxes and distortion changes with eye position to be small, so that an optical system nearly free from them can be obtained by optimization design for HUD optics
