Factor analysis, an important research method, has been conducted as a pre-analysis of empirical researches. Sometimes, the researchers expect more information than factor analysis' limitation as well. Therefore, I suggest a method to overcome this problem. This study presents a combined research method which allow to solve the limitation of the factor analysis in social science. The combined research method consist of factor analysis, AHP(analytic hierarchy process) analysis, diffusion theory and system dynamics, which is able to explain causalities.

Korean government built "2040 Science and Technology Future Vision" in order to show positive future scenarios and suggest a long-term guideline for a progress in science and technology. The S&T Future Vision was built based on an analysis of global megatrends and a prospect of domestic social change. After building S&T Future Vision, the "Government R&E Strategy"s was established as a follow-up action plan. The Government R&D Strategy consists of lists of future emerging technologies for future leadership, government R&D investment status and investment portfolio plans. Exploring future emerging technologies aggressively and making a governmental R&D strategic policy are requirements for national competitiveness, leadership in the world. Therefore search and selection for future emerging technologies is getting more and more important recently. Generally qualitative methodologies have been used such as expert-panel discussion method and portfolio analysis with expert valuation method in order to explore future technologies. These experts-based qualitative methodologies are well defined but lacking in some objectivity because size of expert-panels has limitations. We suggest a quantitative methodology, science mapping method to compensate this shortcoming in this study. There is another limitation related governmental R&D strategy which is that general R&D portfolios are static until a point of technology realization. We also propose a dynamic R&D investment portfolio which present different portfolios at a intermediate point and a point of technology realization. We expect this try with science mapping method and a dynamic R&D portfolio could strengthen strategic aspect of government R&D policy.

In this paper, we conducted a comparative study on the methodology for impact analysis as the economic grounds for formulating policy and investment plan concerned with utilizing spectrum resource. In order to provide numerical results for objective comparison and selection among policy and investment planning, methods to be analyzed are focused on quantitative methodology based on mathematical models, consequently the utility and limits of econometric model, input-output analysis, computable general equilibrium and system dynamics are compared from various viewpoints including analysis cost. Besides, we compared the methodologies in the standpoint of utilizing spectrum and discussed the recent findings of mixed models combining multiple methodologies to exploit the advantages of each methodology and to offset the limit. Results of the research can be used as reference indicators to select the method that conforms to the purpose and priority of analysis verifying the efficiency of execution of policies and investment plans.

본 연구는 과학 커뮤니케이션 분야에서 널리 쓰이고 있는 뉴스 내용분석 방법론이 하이프 사이클 모델에 부합하는 지를 탐색적으로 살펴보고자 한다. 즉 과학기술 뉴스 내용분석이 하이프 사이클 모델에서 설명하는 사회적 가시성의 실체적 파악을 위한 기술기획의 유용한 보완적 방법론으로 쓰일 수 있음을 밝히는데 본 연구의 의의가 있다. 이를 위해 대표적인 유망기술로 클라우드 컴퓨팅을 대상으로 뉴스 내용분석을 수행하였다. 분석의 초점은 클라우드 컴퓨팅 기술 관련 뉴스의 빈도, 보도태도(긍정, 중립, 부정), 5가지 뉴스 프레임 관점에서 분석이 이루어졌고, 뉴스 보도경향이 하이프 사이클 흐름을 따라가는 지를 살펴보았다. 종합지 경제지와 IT전문지를 대상으로 한 뉴스 내용분석 결과는 뉴스 빈도, 보도 태도, 뉴스 프레임 모두 하이프 사이클의 흐름을 따르고 있었으며, 특히 2014년 이후의 흐름은 하이프 사이클 상에서 기대붕괴 지점을 지나 현실인식의 지점으로 진화되는 시점임을 추론할 수 있었다. 본 연구결과는 최근 확산되고 있는 텍스트 마이닝, 감성어 자동식별 분석 기술 등과 접목하여 사회적 맥락 파악을 위한 기술기획 분석의 보완적 방법론으로 기여할 수 있을 것으로 판단된다.

Digital Humanities System is a method to effectively share and spread Humanities information and knowledge to users by using information technology. It Also comes into the spotlight as a new research methodology for researches of Humanities researchers. Digital Humanities System distinguishes itself from other existing information systems. Therefore, when the system is developed, it needs to supply with manpower related to development process which is specialized for Digital Humanities System, not for the several established construction methodology. Digital Humanities System studies recently is mostly constructed using the usual methodology of information system construction. Because of its falling efficiency and usability after constructing the system, however, examples of failure of operating system occur. In this paper, accordingly, effective and creative Digital Humanities System development methodology will be studied from the point of view of information technology through collaboration with various field of expertise. In detail, based on information system methodologies in software engineering perspective, we propose a methodology to build a specialized system in the digital humanities.

인지의 주체로서 마음을 연구하는 인지과학은 인간 마음이 가지고 있는 본성을 탐구하고 인간이 가지고 있는 정보전달체계(information processing system)를 밝힘으로써 미를 컴퓨터에 응용하려는 것이 그 목적 중의 하나이다. 이러한 맥락에서 인식론도 어떤 명제를 믿는 것이 정당성을 갖느냐, 다시 말해서, 어떤 명제를 믿어야 하느냐는 규범적 문제보다는 실제로 우리가 어떻게 믿음을 형성하고 있느냐는 서술적인 문제에 중점을 두는 자연주의적 인식론이 큰 세력을 얻게 되었다. 자연주의적 인식론의 대두와 함께, 그것이 규범적인 문제를 다루는 전통적인 인식론과 이떠한 관계가 있는가에 많은 철학자들이 관심을 표명하였다. 그 중 콰인(W. V. O. Quine)은 자연주의적 인식론이 전통적인 인식론을 대체해야 한다는 급진적인 주장을 하였으며, 콘블리쓰(Hilary Kornblith)는 전통적인 인식론과 자연주의적 인식론이 같은 목표를 향한 다른 방법론을 쓰는 것이므로 적어도 전통적인 인식론자들은 자연주의적 인식론의 영향을 받아야만 한다고 단언하였다. 본고에서는 이 두 사람의 논증을 살펴보고 전통적인 인식론과 자연주의적 인식론이 얼마나 밀접하게 연결되어 있는가를 검토해 보기로 하겠다.

Social phenomena require the fundamentals of novel scientific epistemology and methodology due to the continual change by complex variables. A systematic understanding of paradigm shifts is also necessary for analyzing the problems currently faced in society. This study presents chaos theory, which was developed from the natural sciences, to discuss the abnormality of modern society that underscores the importance of the chaos paradigm. Chaos theory is applicable to diverse social phenomena that stretches across politics, economics, and sociology. If social science research can appropriately and effectively develop and apply chaos theory, the theory can be utilized as a useful paradigm to reinforce the fundamentals of epistemology and methodology in exploring social phenomena.

In this study, I took the evidence-explanation (E-E) continuum perspective to examine the epistemological implications of scientific reasoning cases designed by preservice elementary teachers during their simulation teaching. The participants were four preservice teachers who conducted simulation instruction on the seasons and high/low air pressure and wind. The selected discourse episodes, which included cases of inductive, deductive, or abductive reasoning, were analyzed for their epistemological implications-specifically, the role played by the reasoning cases in the E-E continuum. The two preservice teachers conducting seasons classes used hypothetical-deductive reasoning when they identified evidence by comparing student-group data and tested a hypothesis by comparing the evidence with the hypothetical statement. However, they did not adopt explicit reasoning for creating the hypothesis or constructing a model from the evidence. The two preservice teachers conducting air pressure and wind classes applied inductive reasoning to find evidence by summarizing the student-group data and adopted linear logic-structured deductive reasoning to construct the final explanation. In teaching similar topics, the preservice teachers showed similar epistemic processes in their scientific reasoning cases. However, the epistemological implications of the instruction were not similar in terms of the E-E continuum. In addition, except in one case, the teachers were neither good at abductive reasoning for creating a hypothesis or an explanatory model, nor good at using reasoning to construct a model from the evidence. The E-E continuum helps in examining the epistemological implications of scientific reasoning and can be an alternative way of transmitting scientific reasoning.
