본 연구의 목적은 뉴미디어의 특성을 이해하기 위해 활용되는 상호작용성 개념의 폭넓은 함의를 인지하고 그것을 구체화시키는 것이다. 이미 제안된 여러 상호작용성의 유형들을 참고하여 우연적인 상호작용성(contingent interactivity)을 고려하였다. 우연성이란 수행이나 선택이 필연적이거나 확정적인 것으로 간주할 수 없는 상태를 말하며, 또한 주체의 활동이 다양하게 이루어질 수 있는 잠재성을 말한다. 이러한 관점에서 우연적 상호작용이란 메시지나 콘텐츠를 대하는 사용자들의 관여가 필연적인 것이 아니고 실험적이거나 창의적인 경우를 말한다. 상호작용은 콘텐츠의 완성이나 특정한 현실의 몰입을 지향하지 않는다. 오히려 우연적 수행의 결과는 최종적 콘텐츠가 아니며 또 다른 사용자들의 상호작용을 유도하는 특성을 지닌다. 본 연구는 이렇게 개념화된 우연적 상호작용성의 의미를 영화 리컷과 게임 모딩의 두 가지 사례로 고찰하였다. 두 가지 경우 모두 상호작용을 행하는 주체가 우연적인 상황에 놓여있으며, 아울러 리컷이나 모딩을 통해 개별적인 콘텐츠들이 지속적으로 창출되도록 한다는 점을 이해할 수 있다.

We have proposed and fabricated the new bottom-gated polycrystalline silicon (poly-Si) thin film transistor (TFT) with a partial amorphous-Si region by employing the selective laser annealing. The channel layer of the proposed TFTs is composed of poly-Si region in the center and a-Si region in the edge. The TEM image shows that the local a-Si region is successfully fabricated by the effective cut out of the incident laser light in the upper a-Si layer. Our experimental results show that the ON/OFF current ratio is increased significantly by more than three orders in the new poly-Si TFT compared with conventional poly-Si TFT. The leakage current is decreased significantly due to the highly resistive a-Si re TFTs while the ON-series resistance of the local a-Si is reduced significantly due to the considerable inducement of electron carriers by the positive gate bias, so that the ON-current is not decreased much.

Meat becomes brown and rancid during storage in the refrigerator and display in the case. Color changes, metmyoglobin formation and lipid oxidation are the important problems in the transportation / distribution of meat and retail display. The freshness of meat is determined by the sense of vision and smell. Since conventional method determining lipid oxidation is time consuming and destructive (it needs to homogenize meat with reagents, filtrate, time for reaction and read optical density using spectroscopy), more rapid and nondestructive technical tools are desired. The objective of this work was to evaluate near-infrared spectroscopy as an analytical tool for determining meat color, metmyoglobin formation and lipid oxidation. in beef, pork and chicken. Semitendinosus and longissimus thoracis muscles from six beef steers, biceps femoris and longissimus thoracis muscles from twelve LWD crossbred pigs, and superficial pectoral muscles from twenty-four broilers were used. About a 5-cm diameter and 1-cm thick sample (20.0g) was cut from the muscle and placed on plastic foam, over-wrapped with PVC film, and displayed under flourescent lights at 4 degrees C. during 10 days for beef and pork or 4 days for chicken. The spectra was measured by NIR systems Model 5500 Spectrophotometer using fiber optic scan at range of 400 - 1100 nm. Data were recorded at 2 nm intervals and 10 scans / 10 sec were averaged for every sample. Data obtained were saved as log 1/Re, where Re is the reflectance energy, and then mathematically transformed to second derivatives to reduce effects of differences in particle size. $L^{*}$, $a^{*}$ and $b^{*}$, and metmyoglobin formation were determined by conventional spectrophotometer using the integrating sphere unit. 2-Thiobarbituric acid reactive substances (TBARS) were measured for lipid oxidation. A multiple linear regression was used to find the equation which would best fit the data. The number of wavelengths used in the equation was selected based on the fewer number compared to the increasing multiple correlation and Decreasing standard error. (omitted)
