1. 설계목표
- 설계 제한 조건을 고려하여 단일 유리로 해석을 하여 냉난방 용량을 구하고, 에너지 절약을 위 하여 여러 가지 개선책을 고안하여 타당성을 검토한다.

Thanks for the horse.
Hes a shy child, yet comfortable with Catherine.

You liked him?
CATHERINE
Hes beautiful...
Edward smiles, delighted he made her happy.

(ηabs : the absorption efficiency of the materials
ηdiss : the efficiency of exciton dissociation
ηout : the collection efficiency of separated charge carriers)
◈ Sun light reflection should be reduced as much as possible
at solar cell’s surface, for high Jsc
◈ lower band gap → higher Jsc
→ Higher efficiency of solar cell!!
Information System will be Virtual Reality (VR) meetings using computerized holographic projection, as these technologies have become available and is possibly being prepared and developed for mass marketing. As an obvious implementation of 3D Holographic Projection Technologies, virtual reality and spectral imaging will also be made available for sales presentations. By presenting the product
reflection.
In the micrometer scales of water, add the nano scales of
coloid.
Then, the coloids are surrounded by water, and they arrange themselves(the form of 3D photonic crystals).
After that, evaporate the water, we can get the photonic
crystals.
If the water replaced with photosensitive liquid, we can save the evaporation time.

Blackness. Then a hint of green becomes EARTH. It lies across an expanse of space. Richly colored. Fertile.
A GIGANTIC ASTEROID cuts into frame, Burning into EARTHS ATMOSPHERE and striking down in the currant area of Guzumel, Mexico.
Voice : An impact equivalent to ten thousand nuclear weapons detonating simultaneously.
A HUGE DINOSAUR FOOT steps down hard and is VAPORIZED with a deafening ROAR.
Silent and endless. The stars shine like the love of God... cold and remote. Against them drifts a tiny chip of technology.
CLOSER SHOT
It is the NARCISSUS, lifeboat of the ill-fated star-freighter Nostromo. Without interior or running lights it seems devoid of life. The PING of a RANGING RADAR grows louder, closer. A shadow engulfs the Narcissus. Searchlights flash on, playing over the tiny ship
