Animation is showing the highest record in entertainment around the world and writing the history of 3D animation again. The image contents effect thanks to the proper introduction of the state-of-art digital technology, which is one of the causes of the outstanding entertainment and the factual reproduction of the images, provided an opportunity to transmit the meaning of image aesthetics, which is a virtual reality and image reproduction through the reality realization of photo medium, and to reinterpret the boundary of virtual reality. Especially, the development of digital contents technology due to scientific technologies demolishes the boundary of virtual reality and reality and creates the effect of making viewers be absorbed by realizing the virtual reality by means of 3D reality images which highlight the special characteristic of photos. The aspect of the contents technology and image aesthetics which can be interpreted in a view point beyond the existing concept of reality is found in the aura theory of Benjamin and in the Simulacres of Baudrillard. The 3D image by photo-reality herein presents various suggestions in the aspect of real existence of spatial expression, the meaning creation process of reality, the existence value of virtual images.

At the recent 19th General Election, Korean papers waged a surrogate war for the parties they share ideology with. All the conventional practices remained the same - the horse race-like presentations, furthering of confrontations, disregarding policy issues, allocating larger space for commentaries and negative issues, and etc. On top of these, papers began to focus on generational conflicts and individuals at the center of widespread attention and controversies, as a new trend. Photo images are largely used in the commentaries and articles dealing with confrontational or controversial situations. Of course, while the visual images seem to reinforce the emotional appeal of the messages papers try to get across, the potential problems need be noticed that could rise when irrelevant images are used.

Poly(vinyl alcohol) (PVA) composites with various graphite oxide (GO) contents (0 to 10 wt%) were prepared by sonicating the mixture of PVA and GO, followed by crosslinking with glutaraldehyde. GO was pre-treated with oxyfluorination ($O_2:F_2$ = 8:2) in order to modify the surface of GO to allow it to carry hydrophilic functional groups. PVA/GO composite hydrogels were characterized by scanning electron microscopy and Fourier-transform infrared spectrometer (FT-IR). The morphology of the PVA/GO composite hydrogels and the variations in soluble gel portion were investigated under various GO contents and UV irradiation doses. The variation in the chemical structure of photo degraded PVA/GO composite hydrogels was studied by FT-IR. The photochemical stability of PVA/GO composite hydrogels under UV irradiation was found to improve noticeably with increasing content of uniformly dispersed GO.

In recent, there has been a great change in the shopping market due to the development of the Internet and the generalization of mobile devices. Customers have become more comfortable with online shopping where they can purchase clothes without having to visit their own shop directly. While online shopping is convenient and easy to buy, it is difficult to judge whether it is suitable for you to buy clothes. This paper proposes an application that users virtually coordinate on their own full-body photo or a user-specified model. The proposed application encourages smart purchases by enabling users to see their virtual coordination on their bodies.

As social network service platforms grow and one-person media market expands, people upload their own photos and/or videos through multiple open platforms. However, it can be illegal to upload the digital contents containing the faces of others on the public sites without their permission. Therefore, many people are spending much time and effort in editing such digital contents so that the faces of others should not be exposed to the public. In this paper, we propose an automatic face hiding system called 'autoblur', which detects all the unregistered faces and mosaic them automatically. The system has been implemented using the GitHub MIT open-source 'Face Recognition' which is based on deep learning technology. In this system, two dozens of face images of the user are taken from different angles to register his/her own face. Once the face of the user is learned and registered, the system detects all the other faces for the given photo or video and then blurs them out. Our experiments show that it produces quick and correct results for the sample photos.

Technologies related to sealed-type ultrasonic sensors and driving circuit modules for them are the key elements for intelligent robot industry. Those technologies are believed to yield a drastic enhancement of the performance measuring distances in the intelligent robot systems. Modulization technologies of ultrasonic sensors are expected to develop ASIC and MEMS technologies in the future. The size of domestic market for sealed-type ultrasonic sensor modules is expected to grow to 1 billion and 5.72 billion Won by 2008 and 2012, respectively. Recent interest to service robots and government-driven programs are promoting the rapid growth of the market for the service robots. Successful application of the sealed-type ultrasonic modules to the service robots is expected to replace the conventional photo-sensors in a near future.

North Korean youth is a youth aged 6 to 18 who lives in a South Korean society after having left North Korea. In this study, photo-in-education (PIE) provides North Korean youths with opportunities for cultural and arts education, and to help them adjust themselves to South Korean society. As a result, they, as young people who are exploring a new life in South Korea, have been able to express their own inner world through photos, videos, and writings. Also, young people have developed a bright and clear mind, and enhanced an expressive power and logical power that helps grow healthily and intelligently. Further, it is the aim of this education to help them to have a positive feeling for society and to do their best to become a healthy member of society, who will be able to contribute to society. Through PIE, it was found that North Korean defectors were able to see themselves positively and express their own inner self positively, despite that they are still in the negative and shady side of life.

$TiO_2$ films were modified by adding a glass frit as a light scattering particle and applied to an anode electrode in dye-sensitized solar cells (DSSCs) to enhance the adhesion between $TiO_2$ and fluorine doped transparent oxide (FTO). Low melting point glass frits at contents of (3 to 7wt%) were added to the nano crystalline $TiO_2$ films. The light scattering properties, photovoltaic properties and microstructures of the photo electrodes were examined to determine the role of the low glass transition temperature ($T_g$) glass frit. Electrochemical impedance spectroscopy, Brunauer-Emmett-Teller method and scratch test were conducted to support the results. The DSSC with the $TiO_2$ film containing 3wt% low Tg glass frit showed optimal performance (5.1%, energy conversion efficiency) compared to the $TiO_2$-based one. The photocurrent density slightly decreased by adding 3wt% of the frit due to its large size and non conductivity. However, the decrease of current density followed by the decrease of electron transfer due to the large frit in $TiO_2$ electrode was compensated by the scattering effect, high surface area and reduced the electron transfer impedance at the electrolyte-dye-$TiO_2$ interface. The stability of the photo electrodes was improved by the frit, which chemically promoted the sintering of $TiO_2$ at relatively low temperature ($450^{\circ}C$).
