The pseudo hologram provides a floating image to audience by reflecting the projected digital content on flat screen. However, this technique fails to provide 3D effect according to the audience’s viewpoint so that it has been mainly used in the field of the stage performance whose viewpoints are fixed. In this paper, we present a framework of the 3D pseudo hologram that can generate natural hologram images according to audience’s viewpoint. We use a 3D physical mock-up as a projection screen and project digital content onto the mock-up to generate the pseudo hologram image having 3D effect. The proposed system is an appropriate technique for digital exhibition to be provided by various viewpoints. In particular, it is expected to be utilized for digital museums, product promotion, and media art.

A beneficial radioprotective agent has been used to treat the radiation-induced lung injury. This study was performed to investigate whether curcumin, which is known to have anti-inflammatory and antioxidant properties, could ameliorate radiation-induced pulmonary inflammation and fibrosis in irradiated lungs. Rats were given daily doses of intragastric curcumin (200 mg/kg) prior to a single irradiation and for 8 weeks after radiation. Histopathologic findings demonstrated that macrophage accumulation, interstitial edema, alveolar septal thickness, perivascular fibrosis, and collapse in radiation-treated lungs were inhibited by curcumin administration. Radiation-induced transforming growth factor-${\beta}1$ (TGF-${\beta}1$), connective tissue growth factor (CTGF) expression, and collagen accumulation were also inhibited by curcumin. Moreover, western blot analysis revealed that curcumin lowered radiation-induced increases of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), TNF receptor 1 (TNFR1), and cyclooxygenase-2 (COX-2). Curcumin also inhibited the nuclear translocation of nuclear factor-${\kappa}B$ (NF-${\kappa}B$) p65 in radiation-treated lungs. These results indicate that long-term curcumin administration may reduce lung inflammation and fibrosis caused by radiation treatment.

Radiation-induced transforming growth factor-Ղ1 (TGF-Ղ1), connective tissue growth factor (CTGF) expression, and collagen accumulation were also inhibited by curcumin. Moreover, western blot analysis revealed that curcumin lowered radiation-induced increases of tumor necrosis factor-Ձ (TNF-Ձ), TNF receptor 1 (TNFR1), and cyclooxygenase-2 (COX-2). Curcumin also inhibited the nuclear translocation of nuclear factor-ՊB (NF-ՊB) p65 in radiation-treated lungs. These results indicate that long-term curcumin administration may reduce lung inflammation and fibrosis caused by radiation treatment.
