Train to Busan(2016) and Seoul Station(2016) contain trans-media properties in terms of the expansion of 'possible worlds' from the original story, and show the cultural and economic potential of the domestic trans-media contents with industrial systems added to the artist's competence of Dir. Yeon Shang-ho, an animator and film director. But they also have limits of the lack of continuity in time and characters between each media, various derived contents and suitable marketing strategy. For the development of Korean trans-media contents, it is necessary to extend the range of contents, find changes in production time and style, and improve the distribution environment to encourage a user to integrate contents from each platforms.

The purpose of this study is to investigate the mechanical properties of floor slab structures with high-strength and lightweight CFRC panel using fly ash, PAN-derived and Pitch-derived carbon fiber. As a result, the flexural strength of CFRC is remarkably increased by CF contents, but compressive strength of the CFRC is not so increased as flexural strength. The bulk specific gravity is influenced by FA contents more than by CF contents, The compressive strength and the flexural strength are increased by FA contests, but decreased the case of 30% of contents. In order to increasing the flexural-carrying capacity of floor slab structures, it is recommended that the shape of anchor for reinforcement is required type-C and the spacing of anchor is required below 60mm.

In this study, we derived key factors required for the activation of the domestic e-book market and evaluated its importance. Specifically, we derived key evaluation items of C-P-N-D ecosystem perspective through literature review. In addition, we analyzed the implications by evaluating the importance depending on AHP after derived items were modified and classified together with the publisher working group. As the results of analysis, experts considered price(0.785), quality(0.149) and service(0.066) as the important items among three items derived as the primary upper class. A total of 23 factors were derived as the secondary lower class. The importance depending on C-P-N-D areas is as follows: contents(0.43), platform(0.35), device(0.11) and network(0.05). Among the entire sub-factors, three items such as 'distribution of profits with platform', 'profitability of product costs of contents' and 'appropriate rental price of contents and streaming service' showed significantly higher importance than that of other 20 items.

The objective of this study was to derive approximate closed-form error rates for M-ary burst symbol transmission (MBST) of dual-hop adaptive decode-and-forward (ADF) cooperative relay systems over quasi-static Rayleigh fading channels. Within a burst, there are pilot symbols and data symbols. Pilot symbols are used for channel estimation schemes and each relay node's transmission mode selection schemes. At first, our focus was on ADF relay systems' error-events at relay nodes. Each event's occurrence probability and probability density function (PDF) were then derived. With error-event based approach, we derived a tractable form of PDF for combined signal-to-noise ratio (SNR). Averaged error rates were then derived as approximate expressions for arbitrary link SNR with different modulation orders and numbers of relays. Its accuracy was verified by comparison with simulation results.

The purpose of this study was to develop indicators for quality management of educational institutions, and to achieve this, literature analysis and expert interviews were conducted. Through literature analysis, the components of TQM were derived focusing on factors to improve the quality of education, engineering education accreditation standards, and a representative education accreditation system, were considered. Additionally, seven areas as well as 32 indicators required for education quality management, were derived by comparing the EFQM excellence model and the MBNQA education model, applied for quality management of companies and institutions. By comparing and synthesizing these results, a draft was developed for the quality management index of educational institution. Next, opinions on correction and supplementation of quality management indicators derived from literature analysis, were collected from five education experts. From the comparisons and integration of these results, eight criteria (leadership, strategy, customers, people, facilities and environment, curriculum management, curriculum improvement, and performance management) and 34 indicators, were proposed for quality management indicators for educational institutions. Curriculum management, people, and performance management criteria were considered more significantly in quality management of educational institutions, and several implications are suggested based on the study results.
