The Government Informatization Policy Plan represents the government's technology policy vision and a set of ICT policy agenda and initiatives for the tenure of the government. The Policy Plan, however, normally produces an excess of disconcerted and superfluous ICT policy proposals from various policy units in the government. To cope with the superficiality of the ICT policy set in the Policy Plan, this paper proposes an analysis of the epistemology of the policy set. A policy is constructed as an argument and the structure of the policy argument is analysed using a model of argumentation. The findings show that the present informatization policy is driven by three epistemological motives - the production, consumption, and performance of the ICT Technology. The various assumptions and premises that underlie and direct the generation of ICT policy arguments with different motives are idenfied and then are exposed to strong rebuttal arguments to evaluate their epistemological tenability. The policy implications of the epistemological analysis are discussed in the end.

The purpose of this research is to analyse Korean elementary mathematics curriculum taking a philosophical view of mathematics education. In this research, 1 will analyze not only the current elementary mathematics curriculum but also the past ones. There have been intermittently quantitative and external analysis so far to comprehend the elementary mathematics curriculum. But, I thought we also need qualitative and internal comprehension and examined the curriculums through a philosophical analysis. Generally, mathematics curriculums at every period have their own mathematical philosophy consciously or tacitly. And, the school mathematics is the practice of mathematics curriculum based on that mathematical philosophy. Mathematical curriculum reflects both the philosophical aspect in mathematical philosophy that forms the background of the mathematical curriculum and the sociological aspect in real-class that is the output of the curriculum. With this view, the logic of social constructivism can be an appropriate way that leads mathematical philosophical analysis and sociological analysis in mathematics education. So, I comprehend the tendency of the Korean elementary mathematics curriculum from the first to the seventh through the philosophical views. In view of the results so far achieved, after the second half of the 20th century, the Korean mathematical curriculums mainly have the tendency from the Ideology of progressive educator (the first) to of technological pragmatist (the second), from that of old humanist (the third and forth) to progressive educator (the fifth and sixth), and lastly that of social constructivism (the seventh).

The purpose of this study is to derive policy implications in allocating day care centers for the elderly with more efficiency and/or equity by calculating and analysing the accessibility scores of individual dongs to day care centers for the elderly in Seoul using GIS spatial analysis techniques. The study finds that the spatial distribution of the centers does not respond to the distribution of the potential users very well and that dongs in Gangseo-gu and Songpa-gu at the outskirt of Seoul has the lowest level of accessibility. The findings of the study has policy implications in the management of day care centers for the elderly. First, in order to improve the accessibility of the elderly to the centers, an increase in the number and the capacity of the centers needs to be made especially in areas with lower level of services provided. Second, if policy decision is made in the way to increase the capacity of the existing centers rather than to increase the number of centers due to, for example, the budget limit, capacity expansion needs to be made in the centers with higher proximity in order for more elderly people to use the centers more frequently with easy access. Finally, this type of accessibility analysis techniques needs to be used to allocate, expand, and evaluate other types of care facilities for the elderly and social welfare facilities in order to preserve the welfare right of the users of the facility who usually have a lower mobility and to assure the necessity of the resource investment.

The character is not dependent on an original story world any more. It is not limited to it's own story, but gets out and expands the other story with new character, background story, and event regardless of genre and media. The purpose of this study is to analyze why should this phenomenon happen from the media perspective and to build a character storytelling model through the specific examples. With the advent of the digital paradigm the storytelling model is emphasized character storytelling. Character is no longer limited to just one narrative and extended beyond the boundary narrative, media and genre. There are four background. First, disappearance of the big story with the advent of postmodernism and the emergnece of small story. Second, the emergence of fandom culture and charater's liberalization. Third, character as public goods with database. Fourth, changes in author's position. In fact, in the traditional narrative theory there has been discussion about the character all the time. But character storytelling meets transmedia storytelling, discussions were accelerated. The character was preceded by a narrative independent existence. Even if that character has occurred even while leading cause narrative. In this paper, we suggest two model as specific methodology to expand the story world fixed character. One is phychology transition, another is roll transition. This study get the value to build the new storytelling model with digital paradigm.

In the highly competitive cosmetic industry, each cosmetic brand is striving to increase its profit by providing excellent product quality and delightful marketing campaigns. In this regard, this study investigates consumers' post-purchasing decision-making processes. It considers the two critical post-purchasing behaviors as repurchasing intention and recommendation intention. We posit customer satisfaction and brand image as the key antecedents of post-purchasing behaviors. The effects of cosmetic quality, price fairness, and event activities on consumer satisfaction and brand image are examined. We conducted a questionnaire survey of women in their twenties, which are critical groups in consumer life cycle of cometic products. Data collected from 163 female respondents were empirically tested against a theoretical framework using partial least squares. Analysis results found that both consumer satisfaction and brand image significantly influence post-purchasing behaviors, respectively. Especially, brand image has a stronger effect on post-purchasing behaviors than customer satisfaction does. Cosmetic quality and price fairness play an important role on customer satisfaction and brand image. However, event activities significantly affect consumer satisfaction, while they do not significantly influence brand image.

The purpose of this study was to explore the elements of teaching behavior and classify instructional types through the teacher's classroom observation in elementary school science classrooms. 18 elementary school teachers were selected at Seoul city and Kyungkido. The topic of lesson was 'How the weight of object is changed according to the shape to sink in the water'. Each class was recorded and analyzed that. The teaching behavior elements were used inductional analysis method. The instruction types were classified into instructional organization, teaching strategies in teaching-learning processes, the level of openness of inquiry at science classroom. The validity and reliability of the data were analyzed by 7 science educators. The results of the analysis of the teachers discourse showed that there are 23 types of teaching behavior elements. Used teaching behavior elements revealed the differences from each teacher. There were 7 types among the 12 types of class and the most common types of instruction were unsystematic, teacher-centered, and guided-inquiry. The result showed that guided inquiry type was found more than open inquiry type and teacher-centered instructional, content-centered instructional, superficial inquiry process showed characteristic.

In this study, we introduce a concept of advanced neurofuzzy polynomial networks(ANFPN), a hybrid modeling architecture combining neurofuzzy networks(NFN) and polynomial neural networks(PNN). These networks are highly nonlinear rule-based models. The development of the ANFPN dwells on the technologies of Computational Intelligence(Cl), namely fuzzy sets, neural networks and genetic algorithms. NFN contributes to the formation of the premise part of the rule-based structure of the ANFPN. The consequence part of the ANFPN is designed using PNN. At the premise part of the ANFPN, NFN uses both the simplified fuzzy inference and error back-propagation learning rule. The parameters of the membership functions, learning rates and momentum coefficients are adjusted with the use of genetic optimization. As the consequence structure of ANFPN, PNN is a flexible network architecture whose structure(topology) is developed through learning. In particular, the number of layers and nodes of the PNN are not fixed in advance but is generated in a dynamic way. In this study, we introduce two kinds of ANFPN architectures, namely the basic and the modified one. Here the basic and the modified architecture depend on the number of input variables and the order of polynomial in each layer of PNN structure. Owing to the specific features of two combined architectures, it is possible to consider the nonlinear characteristics of process system and to obtain the better output performance with superb predictive ability. The availability and feasibility of the ANFPN are discussed and illustrated with the aid of two representative numerical examples. The results show that the proposed ANFPN can produce the model with higher accuracy and predictive ability than any other method presented previously.
