Instructional objectives clearly show what teachers should teach in the class and how they lead the class, focusing on a certain activity for their students in the class. Clear instructional objectives are a prerequisite for teachers to accomplish effectively their curriculum. The revised Bloom's taxonomy table of educational objectives has been introduced in 50 years since the publication of his original taxonomy table in 1956. Bloom's revised taxonomy table of educational objectives has two-dimensions, the "cognitive process" dimension and the "knowledge" dimension, and it classifies class objectives more elaborately and clearly. This study was designed to classify instructional objectives stated in elementary science guidebooks for teachers into Bloom's revised taxonomy table, and see how the objectives of elementary science classes were categorized by grade level and areas. In addition, this study examined how the objectives of elementary science classes by study area were classified into the new taxonomy table. This study classified 618 elementary science instructional objectives of third- to sixth-grade science guidebooks for teachers into Bloom's revised taxonomy table. The results showed that the objectives of elementary science classes emphasized disproportionately some of the knowledge and cognitive process dimensions. In the area of subjects while the percentages of factual knowledge were very high, those of meta-cognitive knowledge were low.

A knowledge map, a taxonomy of knowledge repositories, must have capabilities supporting and enhancing knowledge user's activity to search and select proper knowledge for problem-solving. Conventional knowledge maps, however, have been hierarchically categorized, and could not support such activity that must coincide with the user's cognitive process for knowledge utilization. This paper, therefore, aims to verify and develop a methodology to build a networked knowledge map that can support user's activity to search and retrieve proper knowledge based on the referential navigation between content-relevant knowledge. This paper deploys keywords as the semantic information between knowledge, because they can represent the overall contents of a given document, and because they can play the role of semantic information on the link between related documents. By aggregating links between documents, a document network can be formulated: a keyword-based networked knowledge map can be finally built. Domain expert-based validation test was also conducted on a networked knowledge map of 50 research papers, which confirmed the performance of the proposed methodology to be outstanding with respect to the precision and recall.

The application of modern ecological, ultrastructural and molecular methods, aided by the cultivation of numerous cyanobacterial morphotypes, has substantially changed our knowledge of these organisms. It has led to major advances in cyanobacterial taxonomy and criteria for their phylogenetic classification. Molecular data provide basic criteria for cyanobacterial taxonomy; however, a correct phylogenetic system cannot be constructed without combining genetic data with knowledge from the previous 150 years research of cyanobacterial diversity. Thus, studies of morphological variation in nature, and modern morphological, ultrastructural, ecophysiological and biochemical characters need to be combined in a “polyphasic” approach. Taxonomic concepts for generic and infrageneric ranks are re-evaluated in light of combined phenotypic and molecular criteria. Despite their usefulness in experimental studies, the limitations of using strains from culture collections for systematic and nomenclatural purposes is highlighted. The need for a continual revision of strain identification and proper nomenclatural practice associated with either the bacteriological or botanical codes is emphasized. Recent advances in taxonomy are highlighted in the context of prospects for understanding cyanobacterial diversity from natural habitats, and the evolutionary and adaptational processes that cyanobacteria undergo.

The purpose of this study was to explore instructional objectives of 'Wise Life' based on Bloom's Revised Taxonomy of Educational Objectives. It was to extend understanding the 7th and the revised Wise Life 2007 as well. The written objectives of two curriculum of Wise Life were divided into two, the 'knowledge' dimension and the 'cognitive process' dimension based on Bloom's Revised Taxonomy of Educational Objectives. Major activity subjects presented in the 7th and the revised Wise Life 2007 were dominantly the basic inquiry activity types. It was found from this research that the 'factual' knowledge of the 'knowledge' dimension and the 'understand' of the 'cognitive process' dimension took a large proportion of the revised Wise Life 2007 objectives. The 'meta-cognitive' knowledge was increased. 'Remember' of the 'cognitive process' dimension was decreased and the high level objectives as 'analyze' and 'create', in the 'cognitive process' dimension was increased from the 7th to the revised curriculum. The 'factual' knowledge, 'conceptual' knowledge and 'metacognitive' knowledge were engaged with 'understand' and the 'procedural' knowledge were engaged with 'apply'. The 'meta- cognitive' were engaged with 'create' is the 'procedural' knowledge in the revised Wise Life 2007. 'Remember' was decreased. 'Create' was increased in the basic inquiry activities. It was analysed in zero percent of 'Observing', 'Investigating and Presenting', and 'Making'.

Although This study was designed to evaluate internet communities based on knowledge creation and learning. To do so, we created and tested our research model, by using selected 20 different knowledge communities. Using the K-Means Clustering techniques, we found different characteristics and evaluated these characteristics by the criterion. The results of discriminant analysis suggested 4 different models such as 'Search Engine,' 'Open Communities,' 'Specialty Communities,' and 'Activity Communities.' The results of this study indicated that it can cover some reasons for development process of knowledge communities and that it can also create a strategic framework for practical use of knowledge communities.

이 연구는 식물학의 학문분류 체계와 문헌분류 체계를 비교 분석함으로써 식물학의 분류특성과 문제점을 분석하고, 이를 토대로 KDC 식물학의 분류체계를 개선할 수 있는 방안을 제시하고자 시도되었다. 이 연구결과를 요약하면 아래와 같다. 첫째, 식물학의 학문분류는 주로 식물의 연구대상에 따라 식물 형태학, 식물 생리학, 식물 생태학, 식물 계통학, 식물 유전학, 식물 진화학 등으로 구분하고 있다. 둘째, 식물의 분류는 식물 계통학이라는 하위 분과학문에서 다루고 있으며, Engler 체계 등이 일반화되어 있다. 셋째, 식물학의 문헌분류 체계는 대부분 식물학의 분과학문 위주가 아니라 식물의 분류 위주로 구성되어 있다. 이때 KDC, NDC, UDC, CC에서는 식물분류를 식물의 발달과정 즉, 진화순서에 의해 하등식물에서 고등식물로 배열되어 있는 Engler 체계를 적용하고 있으며, DDC와 LCC는 현존하는 식물에 더 중점을 두고, 고등식물에서 하등식물로 배열되어 있는 Bentham & Hooker 체계와 유사성이 있다. 넷째, KDC 식물학에서 있어서는 DDC나 CC와 같이 일반 식물학에서 다루고 있는 식물의 구조나 속성 등을 482-489에 나열되어 있는 모든 식물에 공통적으로 적용하여 세분할 수 있도록 구조화 하는 것이 바람직할 것이다.

The purposes of this study were to classify the objectives in elementary science for the 2007 revised national curriculum in accordance with Bloom's Revised Taxonomy of Educational Objectives, and to compare the classified data of 2007 revised curriculum with 7th national curriculum from a view of creative objectives. For the purpose, the frame and manuel was developed to classify the objectives. In this study, elementary science instructional objectives of third- to forth-grade level were classified through the frame. The finding of this study revealed that the objectives, stated in elementary science for the 2007 revised national curriculum, are biased to the 'conceptional knowledge', 'factual knowledge' and the 'understand' cognitive process dimension. And the remaining dimension of the Bloom's revised taxonomy is very scanty. Comparing with 7th national curriculum, the 2007 revised national curriculum's objectives system has not conspicuous improvement in creativity area. It was suggested to improve present objectives system, because of give learners more experience to opportunity about creativity.

This study examined three elementary school computing curriculum - the CSTA K-12 computer science standards, the computing programme of the national curriculum in England, and the 2015 national curriculum in Korea - focusing on the educational objectives with the perspective of the revision of Bloom's Taxonomy of Educational Objectives. The CSTA K-12 computer science standards mainly addressed applying procedural knowledge and using digital technology is the main theme. The computing programme in England concentrated on understanding factual and conceptual knowledge of computer science, such as algorithms. The 2015 national curriculum also addressed applying procedural knowledge, but the main focus is making softwares and robots. The findings of this comparative analysis suggest that it is needed to set up concrete educational objectives for lower grade and make them related to the secondary education to make more coherent elementary-level learning objectives. And elementary-level computing learning objectives are needed to be organized with the perspective of knowledge and cognitive process level.
