Anxiety for employment of workers has been increased due to rapid change of management environment, which tends to increase psychological instability on the job of all workers. Accordingly, this study examined the moderating effect of self-efficacy between job instability and organizational citizenship behavior. The research subjects were employees of small and medium companies in the manufacturing industry in Daejeon-si, Sejong-si and Chungcheongnam-do and Chungcheongbuk-do. 500 sheets of the questionnaire were distributed from August 5, 2015 to August 30, 2015. Among them, 321 were collected with 64.2% of the response rate. Total 312 sheets were used for analysis excluding 9 sheets with incomplete answers. The results are as follows. Firstly, it proved that job instability had negative (-) effect on organizational citizenship behavior. Secondly, in the relation between job instability and organizational citizenship behavior, there was moderating effect of self-efficacy. Accordingly, if self-efficacy of the workers is higher in the threat of job instability, it means organizational citizenship behavior would increase. In conclusion, in the current situation where there is instable survival of corporation and job, the management of small and medium manufacturing company needs to increase self-efficacy through training and internal reward to employees. The limit of the study is that the research subjects were employees of small and medium companies in the manufacturing industry in Daejeon-si, Sejong-si and Chungcheongnam-do and Chungcheongbuk-do.

A movie information program has a positive effect on the viewer's intention to watch the movie by providing an indirect experience of the movie based on trust. In order to increase the effectiveness of a movie information program, a data service that provides the additional information on the movies introduced in a movie information program has been studied. However, since the study limited the data service to one movie information program, it was difficult to apply it to the actual environment of general cable broadcasting companies or satellite broadcasting companies that transmit multiple movie information programs. Therefore, this study expanded the existing research limited to one movie information program to provide additional information of several movie information programs. This study is meaningful in that it suggests a data service that can be operated in the realistic environment of a broadcaster that actually transmits several movie information programs.

Chungcheongbuk-do can be said that it is not developed well because its surface accounts for 7.5% of Korea's whole land surface, and it accounts for 3.1% of population and main economical index from those of whole Korea. However, Chungcheongbuk-do should develop itself more by integrating of Cheongju-si and Cheongwon-gun, transfer of government facilities to Sejong city, and dispersing manufacturing companies of Seoul Metropolitan area. The factor which affects Chungcheongbuk-do's regional specialized industries is the distance from Cheongju-si and Gyeonggi-do. Service industries are specialized in urban area; manufacturing industries are specialized in regions which are close to Cheongju-si or Gyeonggi-do; and primary industries and consumer service industries are specialized in areas that is far from Cheongju-si. This study can be a foundation for studies on regional and industrial change of Chungcheongbuk-do by looking at its population and location quotient.

In this research paper, the analysis, and improvement, of conditions of fire investigation related to products were derived. The results of the research showed that the main entity that plays the role of coordinator on the scene of fire investigation is unclear, systematic devices to protect the rights and interests of fire victims are inadequate, there are limitations in deriving the cause of fire due to the lack of fire appraisal organizations in fire departments, and the product companies are passive in their initial actions. As for improvement measures, it was found that the adoption of the system in which fire departments can play the role of mediator on the scene of fire investigation, the establishment and operation of fire appraisal organizations and research institutes in fire departments, and the establishment of network between fire departments and product companies are needed.

For decades, the pursuit of volume commercialization of low-power reflective displays with a paper-like look has been an unfulfilled dream. While steady technical progress was made throughout the late 1990s, there were still no volume products incorporating electronic paper displays (EPD) on the market. Now, microencapsulated electrophoretic display technology, also called electronic ink, has moved into volume production with a frontplane laminate (FPL) display component called E Ink Imaging Film™. This film is coated roll to roll on a flexible plastic substrate and integrated into a display module. Today, all-plastic segmented displays are being shipped as well as displays with electronic ink FPL being driven by glass TFT backplanes. A roadmap to active matrix flexible electrophoretic displays is being enabled by rapid technical progress on flexible TFT backplanes by a variety companies. Each of the approaches to these backplanes and flexible active matrix displays has different advantages for the various market segments being pursued including large format flexible displays for e-news and other reader applications, rollable displays for compact readers, and high resolution small format displays up to 400 ppi that can have fully integrated drive electronics to reduce size and drive down costs. Backplane approaches include Si on plastic, organic transistors on plastic, and Si transistors on flexible stainless steel substrate. Progress is also being made on next generation inks, including more reflective inks with higher contrast ratios. A full color 6 inch, 170 pixel per inch (PPI) active matrix display using a newer generation ink has been developed and this will be described and demonstrated. Large format segmented flexible displays will also be described.
