Korea film market is heterogeneously divided market that comes from competition between Korean movies and foreign imported movies. This research empirically analyzes genre differentiation in Korean film market with three dimensions (film audience preference, production and import, box office hit). The results indicate that, first, audiences who preferring Korean movie preferred 'cultural factor oriented genres', but audiences who preferring foreign movie preferred 'high budget oriented genres'. Second, imported foreign movie genre distribution was little bit different with box office hit genre of foreign movies. Foreign movie was imported not only hit genre (action genre) but also low cost genre (comedy and Drama/melodrama genre), but most of all Korean film was produced in box office hit genres (comedy and Drama/melodrama genre), third, Korean movies hit a box office in comedy and Drama/melodrama genre, but foreign movies hit a box office in action and SF/Fantasy genre. Those results show that Korea movies' genres are concentrated very much in cultural factor oriented genre. Those results can give implication of diversity policy and movie production strategy of Korea film market.

Recently, Pleurotus eryngii, King oyster mushroom is the main export item in South Korea mushroom industry. For appropriate transportation to Europe and USA markets, it is necessary to elucidate suitable conditions of storage and treatment of post-harvest during long time shipping. Whole mushrooms were packed with polypropylene anti-fog film (30 um) without trimming. The range of package weight and oxygen permeability of film were 200 g~400 g and 2000~5000 $cc/m^2$, 24 h,atm, respectively. The weight loss ratio was increased with increasing storage time. There were no big differences in weight loss ratio according to package weight and oxygen permeability of film at low temperature storage($4^{\circ}C$). In case of package weight is 400 g and oxygen permeability of film is 3000 $cc/m^2$, 24 h, atm. As a results of freshness, the optimum packing weight and oxygen permeability of film of P. eryngii were 400 g and below 2,000 $cc/m^2$, 24 h, atm, respectively.

Transmittances of SiO2 and ZrO2 thin films, made by the electron beam evaporation method, were measured with a spectrophotometer to be used in determining their optical constants and thicknesses in the envelop method. New color glass lenses with high transmittance, which now can be manufactured in the industry, was successfully designed by using these constants. Also the vacuum evaporator could be mechanically corrected with these constants as correction factors.

Many flat panel displays displays rely on polymeric substrates with thin film coatings, such as anti-reflective, anti-static and hardcoats, to improve optical and mechanical properties of the display. In this paper we briefly discuss the principles underlying the mechanical robustness of such coated structures, and examine two fitness-for-use tests currently employed by the industry. We compare the teachings with some results obtained with our hardcoats and anti-reflective coatings.

The information display industry this century has to improve our life without increasing energy consumption. Suftla technology together with high-performance silicon thin film transistors (TFTs) and ink-jet technology for forming metal-wiring and organic TFTs will play leading roles for achieving this requirement. In this paper these technologies are reviewed and the concept of the information displays in near future is discussed.

Recently, TFT LCD (thin film transistor liquid crystal display) manufacturing industry is more concerned with the ways of cleaning large TFT LCD´s with high pixed density than ever Ultrasonic cleaners with high frequencies like 1MHz (megasonic cleaners) are effective in removing very small particles without causing mechanical damage to the surface. In this study a megasonic cleaner for TFT LCD manufacturing process is developed and the performance is evaluated through experiments. The experimental results show that the developed magasonic cleaners is effective in removing very small particle from the LCD panel.

Ultra short pulse laser processing with the PI (polyimide) substrate is conducted to increase flexibility and radius of curvatures. A femtosecond laser is used to perform micro machining by minimizing the heat effect in PI substrate. The laser processing according to the parameters, such as fabricated line width, depth, laser power, distance between lines, is carried out to understand the characteristics of fabricated lines. A bending test is carried out to evaluate bending shapes and the radius of curvature after bending and spreading it 1000 times. The results demonstrates that the radius of curvature decreases in deepen lines and increases with the augment of the number of the fabricated lines, and distance between lines.
