The America film, Beauty and Beast has grossed over 4,273,401 after being released for 21 days. The growth of movie profit in the video market is also developing rapidly. In this paper, we will focus on the PLF(Premium Large-Format) video technology, because PLF video technology can help audience to enhance the sense of 'immersion' and enjoy a different visual feast. In PLF video technology, IMAX, screen X, 360 degrees circular screen are the most important formats. By comparative analysis of these 3 formats, the biggest difference is their number of screens and appearance. Based on the result we can understand the 3 kinds of PLF platforms better and help us to make a choice between them. In addition, further research about the manufacture method of PLF technology will be discussed.

To understand the postharvest characteristics of soybean sprouts, 5-day-old sprouts were harvested, packed in PE film, and stored at 4, 12, and $20^{\circ}C$ for up to 4 days. In addition, the sprout respiration rate was measured after storage at 4, 8, 12, 16, 20, and $24^{\circ}C$ for up to 20h. During the first day of storage at $20^{\circ}C$, the sprouts maintained temperature-dependent longitudinal growth, especially of hypocotyl length; hypocotyl and root grew 0.8cm and 0.2cm, respectively. The hypocotyl thickness decreased by 11, 13, and $18\%$ after 4 days of storage at 4, 12, and $20^{\circ}C$, respectively. No temperature-dependent differences in fresh weight, dry weight, or water content were found, despite decreases of $3\%$ over the 4 days of storage. A significant postharvest decrease of $50\%$ in vitamin C content was observed in the sprouts stored at $20^{\circ}C$ for 3days. Based on the $CO_2$ production rate, the soybean sprouts exhibited an increase in respiration in proportion to the storage temperature; sprouts stored at 8, 12, 16, 20 and $24^{\circ}C$ showed approximately 2, 5, 6, 11, and 17 times, respectively, than the respiration rate of sprouts stored at $4^{\circ}C$. These results indicate the importance of low temperature storage during market circulation for minimizing the postharvest morphological and nutritional degradation of soybean sprouts.

The remarkable development of digital technologies and the success of 3D stereoscopic films have led to started drawing attention to stereoscopic images. The stereoscopic images have not become a passing fad in the present time unlike in the past, but have constantly showed their potentials. Unfortunately, the domestic stereoscopic images market is faced with difficulties, such as lack of the capital strength and of insufficient production infrastructure, and the production of 3D from 2D. As a result, it is not easy to produce creative stereoscopic animation contents. Therefore, in Korea, more efforts should be made in accumulating a plenty of data on production techniques. In order to make film production reflecting stereoscopy and effective stereoscopic implementation, which are necessary to produce high-quality stereoscopic contents, this thesis gave an explanation about a production technique studied on the basis of 3D graphic. Stereoscopic images are definitely one of the most promising image contents in the 21st digital contents industry. For the reason, in order to produce stereoscopic animation contents with high quality, fundamental studies on the stereoscopic images should be performed in a constant and cautions way.

All over the world, the interest in technology and industrial value has been increasing rapidly due to the continuing commercial successes of three dimensional films. However, after the commercial success of , without exception, lots of three dimensional films had been produced thoughtlessly. Hereby, these films incurred a censure owing to bad degree of completion related to insufficient storytelling and directing. For three dimensional films, characteristic of producing should be considered perfectly in the planning stage unlike previous films. This study concentrates upon proper directing for three dimensional films, and analyzes the method of it, roughly divided into three parts ; the lapse of time, directing the screen which can highlight space sense, and the point of sight. Henceforth, The demand of three dimensional contents will increase all around the world, at such time, we also should take note of the change, and then produce excellent contents which can lead to have a chance to gain the supper hand in the market of three dimensional contents.

Dardenne brothers' films deals with minorities' issues who are shoved out to periphery of society, and especially takes interest in value-deprived human life in labor market of today. This study examines such social awareness of Dardenne brothers targeting their latest works awarded in Cannes Film Festival, , , , , . And analysis is attempted about Dardenne brothers' unique formal aesthetical style that exactly captures such social awareness. In Dardenne brothers' films a person shows up who faces abject matter of living. Their agony is closely connected to unemployment, and shows images of irresistible anxiety and alienation. Dardenne brothers' images are not only simple platform with contents embodied, but designed form showing essential thematic consciousness. Location and gaze, motion of camera capturing a character makes us to reflect the situation a character is facing in the world. There are almost no regard about plots, no dramatic devices, superficial and even straightforward, but Dardenne brothers' films have such independent formal aesthetic, which makes able to give endless tension.

This study investigated the effect of films treated with anti-fogging (LA) agent on the freshness extension of 'Fuji' Apples. Preference, weight loss, total ascorbic acid, sugar content, acidity, change of gas composition in package were evaluated during storage at $15^{\circ}C$. After 150 days of storage, the weight loss of apples in control (L), LA was 1.0 to 1.1%. Total ascorbic acid content of apples in control after 150 days was 2.09 mg/100g F.W, that of apple in LA was 2.47 mg/100g F.W. The titratable acidity of apple in LA was lower than that in control, while soluble solids content of LA was higher than that in control after 150 days. Ethylene gas adsorbability in control package was 192.2 ppm and that in LA was 195.7 ppm. It was verified that LA treated with anti-fogging agent are few different compare to control, but commerdity on the display in market was considered higher than that of non-treated anti-fogging agent.

This study was conducted to investigate the optimum storage temperature and the effect of ethylene on the postharvest quality of astringent persimmon (Diospyros kaki L) 'Cheongdobansi' fruits. We treated fruits with $10{\mu}L{\cdot}L^{-1}$ ethylene at 20, 15 and $10^{\circ}C$. Our results indicated that higher storage temperature rapidly reduced firmness and astringency. The soft persimmon fruits stored at $15^{\circ}C$ showed the best quality relative to the fruits stored at $20^{\circ}C$ and $10^{\circ}C$. Our findings also showed that ethylene generators, which are sold on the market, can effectively induce persimmons to soften in plastic film.

Currently, e-textile market is rapidly expanding and the emerging area of e-textiles requires electrically conductive threads for diverse applications, including wearable innovative e-textiles that can transmit/receive and display data with a variety of functions. This study introduces hybrid nano-structures which may help increase the conductivity of the textile threads for use in wearable and flexible smart apparels. For this aim, Ag was selected as a conductive material, and yarn treatment was implemented where silver nanowire (AgNW) and graphene flake (GF) hybrid structures overcome the limitations of the AgNW alone. The yarn treatment includes several treatment conditions, e.g., annealing temperature, annealing time, binder material such as polyurethane (PU), coating time, in order to search for the optimum method to form stable conductive nano-scale composite materials as thin film on the surface of textile yarns. Treatedyarns showed improved electrical resistance readings. The functionality of the spandex yarn as a stretchable conductive thread was also demonstrated. When the yarn specimens were treated with colloid of AgNW/GF, relatively good electrical conductivity value was obtained. During the extension and recovery cycles of the treated yarns, the initial resistance values did not deteriorate significantly, since the network of nanowire structure with the support of GF and polyurethane stayed flexible and stable. Through this research, it was found that when one-dimensional structure of AgNW and two-dimensional structure of GF were mixed as colloids and treated on the surface of textile yarns, flexible and stretchable electrical conductor could be formed.

As archives, photograph is the evident records of historical facts and experiences. Thus, it is worth preserving. Unlike other documents silver halide photographic films and prints are quite sensitive to environmental factors such as light, temperature and humidity, which demands careful treatment in preservation. This study was carried out to select popular photographic films and papers on the market, to examine their photographic speeds (or sensitivities) and to compare and analyze their preservative features after keeping them some time in a weather-o-meter. Consequently, B/W materials were superior to color ones in preservation. And films were better than papers in the same manner. But we were not able to observe remarkable differences among material's manufacturers.

Recently, discussions for the eradication of illegal shooting have been carried out in a socially-oriented way. The government has established comprehensive measures to eradicate cyber sexual violence crimes such as illegal shooting. Although the social interest in illegal shooting has increased, the illegal film shooting case is evolving more and more due to the development of information and communication technology. Applications that can hide confused videos are constantly circulating around the market and community sites. As a result, field investigators and professional analysts are experiencing difficulties in collecting and analyzing evidence. In this paper, we propose an evidence collection and analysis framework for illegal shooting cases in order to give practical help to illegal shooting investigation. We also proposed a system that can detect hidden applications, which is one of the main obstacles in evidence collection and analysis. We developed a detection tool to evaluate the effectiveness of the proposed system and confirmed the feasibility and scalability of the system through experiments using commercially available concealed apps.
