The purpose of this study was to find out taxonomic characteristics of objectives infered from questions of summative evaluation by analyzing those objectives with Bloom's revised taxonomy of educational objectives. 1,711 questions of midterm and final examinations collected from 25 middle schools were analyzed to classify objective of each question. The major findings of the study were as follows: first, from the analysis of objectives in the knowledge dimension, the assessment of factual knowledge was most prevailing(67.6%) in the biology summative evaluation. In the cognitive process dimension, memory assessment was most dominant(76.1%). Thus, the main objectives of evaluation leaned toward particular classes in the Bloom's revised taxonomy, which was different from the findings of earlier studies on the weights of evaluation areas. Second, the level of the objectives should be determined in consideration of the grade of middle schoolers, as their cognitive level improves with grade. In fact, however, there was no difference among three grades in characteristics of objective taxonomy.

Learning objectives is used to be a good guidance of a class evaluation and activity design for an effective teaching and learning activities in class. Anderson's taxonomy of Educational Objectives that was a revision of Bloom's taxonomy has presented in research field of other subject matters and used as a better guideline for analyzing learning objectives in textbook and achievement levels in test recently. This study has behaved some questionnaires for that Anderson's taxonomy is suitable for a guideline of stating learning objective in Informatics subject matter, and analyzed the learning objectives in 6 Informatics textbooks by Anderson's taxonomy. It has proposed that Anderson's taxonomy is satisfactory for expressing learning objective of Informatics subject matter in class and some dimensions, such as conceptual and procedural knowledge, understand, and apply, are much more used in learning objectives in 6 Informatics textbooks. This results will be a good case study in research about taxonomy of educational objectives and development of Informatics textbooks.

Education is an intentional and planned change process for achieving the objective. Thus, an educational objects sets is very important in elementary and secondary instructional practice. Bloom created the original taxonomy of the cognitive, affective, psychomotor domain for categorizing level of abstraction of questions that commonly occur in educational settings in 1956. During the 1990, Anderson & Krathwohl, Marzano led a new educational taxonomy which met for the purpose of updating the Bloom's taxonomy, hoping to add relevance for 21st century teaching and learning. The educational taxonomy with information literacy process is relationship. The purpose of this study is restructure of information literacy process based on educational object taxonomy.

The purpose of this study is to propose the expansion of headings for digital trends of Korean Decimal Classification. In order to achieve the purpose, this study first analyzed the change process of classification items related to digital resources in DDC and KDC. Second, subject names related to digital in LCSH and Korean National Library Subject Heading were analyzed. Third, comparisons between the items related to digital of DDC 23rd with LCSH and KDC with Korean National Library Subject Heading were conducted. The result of comparative analysis was identified that KDC 6th edition faces with difficulties in reasonable classification because item names related to digital of KDC 6th edition have 11 items. Therefore, the item related to digital has to be expanded to new classification item name and has to add include notes and class here notes in KDC.

This study has analyzed the learning objectives in 6 Informatics textbooks that were published this year in the basis of 2009 revised curriculum using Anderson's taxonomy of Educational Objectives that was a revision of Bloom's taxonomy and Fuller's taxonomy that was presented for programming activities. Some dimensions of Anderson's taxonomy, such as conceptual and procedural knowledge, understand and apply in cognitive process are much more used in learning objectives in 6 Informatics textbooks. Interpreting and producing dimensions of taxonomy are well presented to balance in 6 Informatics textbooks by analysis of Fuller's taxonomy. This results will be a good case study in research about taxonomy of educational objectives and development of Informatics textbooks.

본 논문에서는 저압 배선 진단 시스템 구축을 위한 퍼지-베이시안 분류기 기반 지능형 차단 시스템 개발을 목표로 한다. Time-Frequency Domain Reflectometry (TFDR)방법이 바탕이 되어 도선의 이상 상태를 측정하게 되며, 진단 부분에서 받은 정보를 능동적으로 해석하고 이상 유무에 따른 차단의 역할을 수행하는 시스템 개발이 최종 목표이다. 제안하고자 하는 분류 알고리즘은 퍼지-베이시안 분류 알고리즘을 중심으로 구성되며, 분류하고자 하는 도선의 이상상태인 damage, open 그리고 short에 대한 분류 기준을 마련하고자 한다. 또한, 실제 저압 배선에서 얻어진 데이터를 바탕으로 퍼지 분류 규칙의 생성 및 분류 알고리즘 생성을 구체화하여 좀 더 나은 성능의 분류기를 개발하고자 하는 것이 본 논문의 목표이다.

This study was to analyze the educational objectives of evaluation of practice quizzes and learning objectives of chemistry I textbooks for the 2009 revised curriculum by Klopfer's taxonomy. The result revealed that the objectives of science education indicated in the 2009 revised curriculum were contained the educational meaning of all categories except 'manual skills' of Klopfer's taxonomy of educational objectives. The learning objectives of chemistry I textbooks laid mostly on 'the knowledge and comprehension' and 'the process of scientific inquiry'. It showed that 'the objectives of scientific knowledge and methods', 'manual skills' and 'scientific attitude and interest', 'orientation' seemed to be taken in a relatively careless way. The result on the practice quizzes in textbooks, they also laid stress on 'the knowledge and comprehension' were covered much, even though they were emphasized in the other objectives of the curriculum. It was concluded that the educational objectives of the science textbooks did not reflect much on educational objectives of the 2009 revised curriculum.

This study was to analyze the subject objectives of Middle school 7th grade Science textbooks based on the Korean 7th curriculum by using Klopfer’s taxonomic system and find out how much compatible they were with the requiring objectives of the curriculum. Particularly, this study makes educational objectives for textbooks coherent wit the requiring objectives of the curriculum, through the analysing the problems. The results are follows. The Middle school science educational objective of the 7th curriculum sets up almost of the objectives through all of the domains of the Klopfer’s taxonomy system, except the operational function (Category G.0), and emphasizes on emotionable domain (Category $H.0\~I.0$) more. However, comparing with an encouragement objective rate of NSTA, Middle school Science textbooks based on the 7th curriculum were published putting more importance in a cognitive domain, and the intention objective (Category I.0) was not mentioned.

자동차 번호판의 이미지에서 번호의 추출이나, 직물 이미지에서 오염 또는 훼손부분의 추출 또는 방사성 폐기물이나 기타 독극물 보관함의 이미지에서 오염이나 산화에 의한 훼손부위 등과 같은 목표물 이미지 추출은 흑백 이미지에서 명암의 차이를 이용하는 것보다는 컬러 이미지에서 색상의 차이를 이용하는 것이 더 효율적일 때가 많으며, 특히 배경과 목표물의 명암차이가 크지 않은 경우에 효과적이다. 배경과 목표물이 갖는 색상의 차이를 이용하여 분리하기 위해서 적색(R), 녹색(G), 청색(B) 의 RGB 평면 또는 순도(H), 포화도(S), 휘도(I)를 사용하는 HSI 컬러 평면 등이 많이 사용되며, 이 때 배경과 목표물의 색상의 히스토그램을 구해보면 보면 많은 경우 유사한 색 정보가 배경과 목표물에 공통으로 포함되어 분리에 어려움을 겪게 된다. 본 논문에서는 Fisher 선형 분리자(Fisher's linear discriminant)[1] 함수를 이용하여 3차원의 색상 특징 벡터를 1차원 직선에 투사하여 변환된 1차원 공간상에서 복잡성을 줄이고 효과적으로 분류할 수 있는 기법을 제안하였으며, 이를 도축된 식용 가금류의 영상에 적용하고 변질된 부분이 포함되어 식용으로 사용할 수 없는 것들을 효과적으로 분류할 수 있음을 보였다.
