The purpose of this study is to suggest the implications for the domestic media education policy which is still in a state of pace by document research of the case in France which has a long history of media education. France has consistently maintained the tradition of the philosophical value of media education, such as 'the cultivation of consciousness and qualities as a democratic citizen' through legal, policy and educational improvement. At the same time, in the digital era, conceptual expansion was carried out that embraced the concept of 'information' rather than resting on classical media education. This was complemented by education legislation, enforcing information education programs in school, and the manage of CLEMI, the media and information education training organization. It will be necessary to construct software system for media education of Korea through the manage of governmental organization and the cooperation system with related institutes under the constant philosophic direction.

This paper examines the significance of records as knowledge information resources that are illuminated by the electronic record environment nowadays based on existing research results and examples. As the production mode of records changes, it is possible to avoid the tendency to prioritize historical and cultural values when keeping records. In addition, according to the change of the operating mode and the work pattern of an organization, the value of knowledge information resource is also important. For this purpose, this paper reviews the recent changes in the work environment in Chapter 2 and then examines attributes not only as evidence but also as information. Based on these discussions, the paper explores the relationship between the records and the information that has been discussed in western academic circles since the 1980s in Chapter 3. With this, it also analyzes the correlation between record management and knowledge management. In Chapter 4, it reviews recent trends to link records management and knowledge management in Australia, the United Kingdom, and the United States. In addition to the current state of public records management in Korea, this paper presents the direction of institutional improvement in three aspects.

In 2012, the International Council on Archives(ICA) distributed AtoM public release, an archival description software based on web, for free to support small archival institutions. The purpose of AtoM project was to let a single or multiple repositories describe archival materials based on ICA descriptive standards and access via a web browser. The value of AtoM project is to promote actual business experience by sharing technical expertise and form active community between users and developers. Recently, there is a growing interest in open source software in the field of domestic record management. This interest is to not only reduce cost, but to escape technology dependencies and to address requirements on the field. The critical mind of this study lies in the fact that there is no practical methodology to establish AtoM system. Even when using AtoM itself, basic tasks such as the migration of the existing data or the improvement of user interface are required. That is why this study suggests the process and methodologies to establish and customize archival information system based on AtoM software.

The purpose of this study is to examines the factors influencing college students' adaptation to College life adaptation, and to investigate the relationship between relationship between variables and College life adaptation. Structured questionnaire was given on 210 freshman, and data was analyzed using SPSS/WIN 22.0. There was a significant correlation between College life adaptation and Department satisfaction (r = .216, p <.001) and Ego identity (r = 395, p <.001). As a result of the statistical significance of the model predicted to College life adaptation, the F statistic value is 12.222 and the significance probability is .000. Variables have significant explanations for college adjustment at a significance level of 0.1. College life adaptation is also explained by 44% variable. If we develop the adaptation program for college life considering variables, it is expected that it will have a positive effect on the improvement of adaptation ability of college students.

Digital technologies in the digital image field are developing and changing rapidly while creating various forms of media environments. In particular, broadcasting image-processing technologies provide more realistic images through the development of multimedia technology. Consequently, the needs of flat image quality have been nearly met, leading to technological saturation. Currently, flat images possess the advantages of popularity and freedom from visual fatigue over three-dimensional stereoscopic images. A complementary technology for flat images is the stereoscopic perception improvement technology. To examine correlations between stereoscopic perception and colour attributes for graphic images on flat displays, we have conducted experiments related to stereoscopic perception and analysed the results. In these experiments, the colour attributes of hue, value, and chroma were applied at different levels. Next, the factors that provide the highest stereoscopic perception and their interactions were analysed through analysis of variance. Finally, this study defines the significance of colour factors related to stereoscopic perception by analysing the experimental results, and proposes a colour adjustment method for improved stereoscopic perception in graphics image processing.

Fuel cell power plant which has advantages as a distributed generation is influenced by high cost of investment and uncertainty of electricity price. This study suggests the model of real options which considers the irreversibility of investment in the fuel cell plant and the uncertainty of electricity price. Most models of real options assume the geometric Brownian motion for convenience, but this study develops the model for the feasibility analysis considering the mean reverting process of electricity price, with the closed form solution on the value of investment option. The result of the empirical analysis considering the data related to the fuel cell generation with the scale of 20MW and the domestic RPS circumstance represents that the investment is feasible without the uncertainty, and is not feasible with the uncertainty. This result implies that the political support as well as the improvement of profit system including revenue and cost are necessary for the activation of the fuel cell power plant.

Background: The diagnosis of pediatric acute respiratory distress syndrome (PARDS) is a pragmatic decision based on the degree of hypoxia at the time of onset. We aimed to determine whether reclassification using oxygenation metrics 24 hours after diagnosis could provide prognostic ability for outcomes in PARDS. Methods: Two hundred and eighty-eight pediatric patients admitted between January 1, 2010 and January 30, 2017, who met the inclusion criteria for PARDS were retrospectively analyzed. Reclassification based on data measured 24 hours after diagnosis was compared with the initial classification, and changes in pressure parameters and oxygenation were investigated for their prognostic value with respect to mortality. Results: PARDS severity varied widely in the first 24 hours; 52.4% of patients showed an improvement, 35.4% showed no change, and 12.2% either showed progression of PARDS or died. Multivariate analysis revealed that mortality risk significantly increased for the severe group, based on classification using metrics collected 24 hours after diagnosis (adjusted odds ratio, 26.84; 95% confidence interval [CI], 3.43 to 209.89; P=0.002). Compared to changes in pressure variables (peak inspiratory pressure and driving pressure), changes in oxygenation (arterial partial pressure of oxygen to fraction of inspired oxygen) over the first 24 hours showed statistically better discriminative power for mortality (area under the receiver operating characteristic curve, 0.701; 95% CI, 0.636 to 0.766; P<0.001). Conclusions: Implementation of reclassification based on oxygenation metrics 24 hours after diagnosis effectively stratified outcomes in PARDS. Progress within the first 24 hours was significantly associated with outcomes in PARDS, and oxygenation response was the most discernable surrogate metric for mortality.

The emergence of environmental and social issues has led to global discussions for the realization of sustainable development. The purpose of this study is to propose a method of sustainable fashion design using waste Hanbok, focusing on men's Hanbok with cultural values. The study utilizes literature research and fashion design development. From the literature study, reform was judged to be a higher concept encompassing reduction, recycling, and upcycling. Reduction is a design method through removal, and recycling design transforms from its original form into a completely different product. Upcycling design focuses on improvement and change in functionality. Accordingly, nine redesigns using men's Hanbok were developed from which three were produced. Consequently, the reduction design demonstrated a small range of variation without changing the item, and cultural sustainability was confirmed through the design that removed the components and recombined the Hanbok. Second, recycling redesign can be reconstituted into a different item. Third, upcycling enables various designs through module assembly, which prolongs the lifespan of the product and confirms its value as a raw material for waste Hanbok. This study is meaningful in realizing sustainable fashion and suggesting practical measures for the sustainability of Korean traditional culture and creative fashion design planning.

This paper propose the VSS-FC-MMA algorithm that is possible to improve the equalization performance based on varying step size to the FC-MMA adaptive equalization algorithm in order to reducing the intersymbol interference effect occurred in the nonconstant modulus signal transmission, and improved performance were confirmed. The FC-MMA is possible to improve the convergence speed, and degrades the steady state performance based on the fixed step size and modified dispersion constant considering the level number of signal symbol for obtain the error signal in adaptive equalization compared to MMA. The proposed VSS-FC-MMA uses varying step size and current FC-MMA possible to improve the steady state equalization performance, it was confirmed by computer simulation. For this, the signal recovery capabilities and residual isi, MSE, SER were applied for performance comparison index in the same channel and signal to noise ratio. As a result of computer simulation, the proposed VSS-FC-MMA improve the risidual value in steady state and SER performance than the FC-MMA, but has 1.7 times slow convergence time by using varying step size.
