본 연구의 주요 목적은 정부에서 추진하고 있는 신재생에너지 보급정책의 현재까지의 성과를 분석하고, 장애요인을 파악하여 개선방안을 제시하는 데에 있다. 따라서 보급정책의 하위 프로그램들의 정성적 평가를 위하여 미국 DOE(Department of Energy) 산하 EERE(Energy Efficiency and Renewable Energy)에서 제시하고 있는 Peer Review Guide(2004)를 따라 외부동료평가(Peer Review)를 사용하였다. 그러나, 미국 EERE에서 제시하고 있는 가이드를 한국에 곧바로 적용함에는 무리가 있기에, 하위프로그램들의 외부동료평가를 실시하기에 앞서서 외부동료평가 설문 평가속성 결정을 위해 전문가 설문을 한 차례 더 진행하였다. 첫 번째 전문가 설문에서는 투입요소의 적정성 (Quality), 생산성 (Productivity), 성취도 (Accomplishments), 연계성(Relevance), 관리 (Management), 전체적 평가 (Overall Assesment) 항목 중 어떠한 항목을 선택해야 하는지, 국문 번역이 적절한지 등을 살펴보았다. 두 번째 설문에서는 이렇게 해서 선정된 항목을 바탕으로 각 프로그램 별로 Peer Review Guide에서 제시한 외부동료평가를 시행할 예정이다.

아키텍쳐 기술 언어(ADL : Architecture Description Language)는 상위 추상화 수준에서의 소프트웨어 시스템의 구조와 행위를 기술하는데 필요한 아키텍쳐 모델 요소들에 대한 직접적인 표현 수단을 제공한다. ADL온 특히 명세 수준의 논리적인 아키텍처를 모델링, 분석하는데 유용하다. 그렇지만 ADL로 기술된 상위 수준의 아키텍쳐 명세가 하위 수준의 구현 시스템으로 어떻게 상세화 되는지 알기가 쉽지 않다. 즉, 상위 수준의 아키텍쳐 명세와 하위 수준의 아키텍쳐 구현 사이에 의미적 차이가 존재한다. 본 논문은 이러한 의미적 차이를 효율적으로 줄일 수 있는 방법을 찾기 위한 일차적인 연구 결과로서, C2 스타일 기반의 ADL로 기술된 아키텍쳐 모델을 Java 구현 코드로 자동 변환하는 방법을 제안한다.

본 논문에서는 메타레벨의 XML 보안 기법을 이용한 처방전 보안 시스템을 제안하였다. XML/EDl의 암호화를 위하여 XML 문서에만 전자서명을 첨부하는 것이 아니라, DTD에 전자 서명을 첨부하는 방법을 사용함으로써 보다 안전한 처방전 전송 시스템을 구축하고자 한다. 처방전 DTD는 처방전의 각 구성요소에 따라 처방전 정보, 환자 정보, 의료기관 정보, 처방내역 정보, 조제내역정보 엘리먼트를 정의하고 그 하위에 정보 전송에 따른 정보를 관리하기 위한 하위 엘리먼트를 정의하였다. 안전한 처방전 전송을 위하여 DTD파일을 읽어 들이면서 파싱을 하고 여기서 추출되는 엘리먼트나 속성, 엔티티들을 해시테이블에 저장한다. 파싱이 종료되면 해시 테이블을 읽어 들여서 메시지 다이제스트를 수행하고 이를 개인키와 합성하여 전자 서명을 생성한다.

This study is a research synthesis analyzing how field geology education is conducted in domestic and foreign countries in the recent 20 years and how it reflects the characteristics of authentic geologic inquiry. For these purposes, we first drew five elements of inquiry in field geology (observation, representation, abductive reasoning, spatial thinking, and diachronic thinking) considering the field geologists' actual research method as well as its pedagogical significance in science education. We developed analysis criteria for field geology education. The 53 cases were analyzed based on each element of inquiry in field geology and its sub-elements, and also the tendency of overall elements. As a result, observation and representation were included in most cases, but there appeared less frequency in order of abductive reasoning, spatial thinking, and diachronic thinking. For observation, the ratio of purposive observation and autonomous observation is high. For representation, both visualizing and linguistic type of representation and free-form representation appear frequently. For abductive reasoning, the step of generating hypothesis is often included and the hypothesis tends to be about the geological formatting process. For spatial thinking, type of self-location and perception of the spatial configuration of the structure appear at a high rate. For diachronic thinking, type of stratigraphic sequence is the most frequent. The proportions of the cases including three or more elements of inquiry in field geology consist 87% of the total. We suggested implications for improving geological fieldwork as authentic science inquiry in the future.

Defoliation effect of two soybean cultivars on the grain yield was studied under different planting densities planted at two different planting date. Leaf removal caused a linear decrease of grain yield with increased amounts of defoliation in the case of lower population densities, while in the case of higher population densities over 40 plants per sqare meter, the slight removal of lower leaves indicated increased grain yields by 13% to 35% compared with control depending on the cultivar and planting time. The pod number per plant was the most effective factor influencing grain yield. The grain weight and the percent of matured grain become more important components for higher yield with decreased population densities depending on cultivar.

The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

Illustrations and letters are two components of school textbooks. In the case of low grades of elementary school, textbook's illustrations play an important role in learning because many parts of curriculums(lessons) are represented by the visual forms through illustrations. So elementary mathematics textbook's illustrations have to make clear mathematical concepts and principles by visual simplification and bring out of the interest and motivation of elementary school students' learning. In this paper, we analysed the external and content aspects of textbook's illustrations, focusing on the textbook of the second grade. We investigated number, kindness, size, ratio, and clearness of illustrations in regard to external aspects. On the aspects of content, we analysed the role of illustrations and the degree of agreement with contents. Also we classified types of error in the textbook's illustrations and presented examples of errors which was found.

The purpose of this study is to draw the elements of encouraging language from the literatures of encouragement and develop the encouraging language model for elementary school teachers. To achieve this, first of all, the literatures about the methods of encouragement were collected. And then the collected literatures were categorized according to the main concept which each literature contained. As a result, 5 categories and 17 subcategories were drawn. 5 categories were valuing a child as a human-being itself, trusting a child, thinking rationally about a child's mistakes, giving a feedback about a child's behaviors non-evaluatively, and reflecting a child's positive feeling. These 5 categories were established as the elements of encouraging language. The encouraging language model was developed on the bases of the 5 elements of encouraging language. The model was constructed of the examples of encouraging language in various classroom situations. The model contains various situations which elementary school teachers often confront in their classrooms. And the model shows the examples of encouraging language proper for each situation. Every example was constructed on the bases of the elements of encouraging language.

Instagram, a photo and image centered social networking service, has received increasing attention these days, from scholars and practitioners. However, little is known about the social and psychological factors that lead consumers to use this service. To provide a baseline understanding on Instagram users, the current study was conducted to discover perfectionistic self-presentation tendency expressed by the Instagram users and explore the relationships between identified perfectionistic self-presentation and intention to use Instagram variables with 250 participants. In addition, this study tried to determine the moderator effect of self-efficacy and self-construal. A comprehensive survey was directed and a total of 380 participants were recruited to verify anticipated hypotheses and research questions. The research results suggest that perfectionistic self-presentation has five sub factors: others conscious self-presentation, subjective self-presentation, environmental adaptation self-presentation, self-expansion self-presentation, and social self-presentation. The implications of this research findings are discussed.
