This study makes an attempt to understand the changes in the National R&D policy by the comparative analysis in terms of R&D policy regime. We characterize the related issues on the National R&D policy, and analyze the direction of science and technology(S&T) policy using the method of scientometrics. The result shows that the policy regime can be categorized into three groups with respect to the R&D efficiency and the keywords; Regime 1: National S&T Innovation 5-year Plan(1999-2002) and National S&T Master plan of the previous adminstration(2003-2007), Regime 2: National S&T Master Plan(2002-2006) and National S&T Master Plan of the previous administration(2003-2007), Regime 3: National S&T Master Plan of the current administration (2008-present).

The purpose of this study was to explore the manners in which models are used in secondary science classrooms. A total of thirteen video-recordings of science lessons dealing with the domains of atmospheric and oceanic earth sciences and their verbatim transcripts were analysed both quantitatively and qualitatively. Interviews with three inservice science teachers were also conducted. Six interrelated assertions were generated as the result of the study: 1) The most frequently used models in secondary earth science classrooms include two-dimensional pictorial, symbolic, iconic, and diagrammatic ones; 2) Science teachers employ models as a mode of representation to make the subject matter available to students; 3) In earth science classrooms, teachers use typical forms of models in intensive manners; 4) Students themselves deal with models on a few occasions, but they just follow similar procedures with the same models; 5) Teachers talk rarely about the nature of scientific models and provide few opportunities for students to think about it; and, 6) Teachers in practice think that the value of using models should be appraised in consideration of the pedagogical intentions of the teacher. Implications for science education and science education research were discussed.

By measuring the consumption risk sharing for the EU regions, we evaluate the performance of various risk sharing channels for the EU. We identify which countries are likely to form the highest risk sharing group among the EU regions by using the DFFITS and DFBETAS diagnostics derived in a statistical regression. Our finding suggests that most western European countries seem to display homogeneous degree of risk sharing. In addition, our result confirms that high risk sharing regions as well as low risk sharing regions are mainly located in many eastern European countries that joined the EU later than western European countries, and implies that the EU members are still dichotomized at large in terms of consumption risk sharing.

The purpose of this study was to establish an analytical framework and quantitative methodologies to analyze 'the cognitive effects of web map use' and to empirically test it. This experimental design was established based on the literature about spatial cognition. Accuracy, reaction time, and confidence within each participant were compared to measure the cognitive effects of web map use for wayfinding. Geometric accuracy of the cognitive maps was estimated and calculated based on the bidimensional regression. The experimental results showed that characteristics of map users and repetition of map use rather than types of map representation did significantly affect accuracy and reaction time of spatial cognition by using web maps. And confidence appeared to be low when the participants referred to both 2D and 3D maps for wayfinding tasks on the web maps. Understanding spatial cognition of web map users, which was suggested in the study, will help cartographers make more effectively-communicated maps.

Among class quantitative tests for the credit rating systems, the credit rating tests for calibration are to test the class homogeneous differences between observed and predicted probabilities. For one time period, binomial test and chi-square test are included, and normal test and extended traffic lights test are also contained for several time peroids. In this work, we consider real data in which there exists correlation among variables, so that these test methods could be applied to the credit rating systems as well as various kinds of the class data such as BWT data and FSI data.

This paper empirically examines the relationship between a firm's external technology acquisition and in-house R&D in Korean manufacturing sectors. Using the technology innovation survey conducted by the Korean government in 2002, and developing a semi-structural empirical model, we find that the firm's in-house R&D and technology acquisition have a complementary relationship: A firm's technology acquisition increases in its in-house R&D. Moreover, government R&D funding and tax incentives have positive effects on the in-house R&D, while the existence of the failed projects encourage a firm to acquire more external technologies.

There have been a great many ups and downs in Korean Credit Card Industries after 2000. It is certain that each Credit Card Company copes with the situations by means of its organizational capabilities. According to the evolutionary view of Institutionalism, a company's capabilities are composed of every day routines, codes, rules, learning(by doing, using, interacting) and decision makings. The purpose of this article is to verify how two Korean Credit Card Companies showed their strategic differences and what factors exposed each company's own limits. To examine the company's ordinary conducts, this study used Q methodology with a random sample of 16 members from each company. Especially from the results of Q factor analysis, it becomes clear that each company still takes a serious view of the economy of scale rather than the innovation or improvement of organizational and relational dynamics.

This research aims to introduce the theoretical basis of the studies of tourism resources, by review the research trends of tourism resources in the geography field. The geographical approaches to tourism resouces can be subdicided into 3 categories according to the subject. First, the classification of tourism resource types and the approach on the spatial distribution may be enumerated. This subject has been the object of the most interest and discussion to the geographers for tourism up to now. And from the viewpoint of contents, it has been developed by classifying the types of tourism resoures, which is based on the establishment of the range and standard of tourism resources and the spatial classification of types based on the distribution feature of the area. Second, the approach about cognition, preference and interpretation on the tourism resources as the background to induce tourism phenomenon and decide the tourism destination. Judging from the fact that most of this subject is starting from the behavioural study and that the right understanding and interpretation of tourism resource is the important factor to decide the preference degree of tourists, we have to have much interest about the field of tourism geoaraphy. Third, the development of tourism resources which is showing the active study recently and its influence and effect attendant upon it may be enumerated. Today, as the economic value of tourism is become important internationally, tourism resources are recognized as the important factor to induce the industrialization of tourism. And in the series of analytical studies related to it the interest has been transferred from the economic benefit analysis attendant upon tourism development including tourism resource and to the cultural, educational, environmental and psychological influence, etc. As the result of composite examination, for the geographical studies about tourism resources, the spatial scale and the contents are being subdivided and specialized. And in the side of subject and method of study, it is developing into the positive study based on the concrete data and the measuring and analytical frame.

최근 하천관리 정책은 단편적인 홍수방어뿐만 아니라 맑은 물을 안전하게 확보하고 건강한 생태계가 유지되는 하천으로 관리하는 방향에 주안점을 두고 있다. 그러나 치수 목적의 하천관리 기술에 비하여 하천환경관리를 위한 기술은 요소기술 개발 및 적용으로 산재되어 있어, 체계가 정립되지 못하고 실무 적용에서도 활용에 한계가 있는 실정이다. 따라서 본 연구에서는 치수, 이수, 하천환경 목적의 다차원 하천관리를 위하여 하천복원의 기술적 체계를 기술수준의 정도를 기준으로 단계별로 정립하였다. 첫 단계는 수문특성, 수리특성, 하상변동/유사특성, 생물/화학특성의 분석이다. 이 단계에서는 각 특성의 현황과 하천복원 방법에 따른 물리특성 변화를 분석하는 것이다. 다음 단계는 하천복원에 따른 정량적인 기대효과 분석이다. 수위저감 및 안정하도 확보, 수질개선, 생물서식처 효과분석 등이 수행된다. 마지막 단계는 하천복원 등의 관리계획에 의한 기대효과 전망이다. 사회경제적 가치, 생물종 다양성 확대가치 등이 분석항목에 포함된다. 각 단계에서는 계량 가능한 지표를 설정하여 계획의 성과를 비교한다. 제안된 다차원 하천복원 기술적 프레임웍을 통해 하천사업에 따른 물리, 생물, 사회, 경제 등 다양한 분야의 구조를 통합한 방법론을 제시함으로써 하도개선 위주의 획일적인 하천복원사업에 변화를 주고, 더 나아가 하천공간 복원 등 적극적인 하천복원사업이 활성화되길 기대한다.
