  • Teacher guidebooks are practical and commonly used resources for teachers to deliver the goals and contents of science curriculum in classroom teaching. Thus, the alignment of teacher guidebooks and science curriculum could be critical to undertake the effectiveness of curriculum implication in science classrooms. This study is to investigate how the learning objectives of science curriculum are implicated in teacher guidebooks by analyzing the dimensions of knowledge and cognitive process in learning objectives in both documents. Grade 3~4 learning objectives (82 objectives in the curriculum, 459 in the teacher guidebook, 541 in total) in 2009 Revised science curriculum and teacher guidebooks were coded and analyzed based on the Revised Bloom's Taxonomy. The analysis focused on how the knowledge dimensions and cognitive processes of the curriculum were emphasized and restructured in the teacher guidebooks to examine the coalition between the two important documents. The study found: 1) the learning objectives in Grade 3~4 in both documents were skewed to certain knowledge dimension (conceptual) and cognitive process (understand); 2) there was a high coalition between unit objectives and lesson objectives in the teacher guidebooks, however, relatively low coalition between the curriculum and the teacher guidebooks; and 3) learning objectives in the curriculum were delivered in teacher guidebooks in various patterns (similar, detailed, additional, in portion, and the same), and 'detailed' and 'additional' were frequently shown. There also appeared new objectives in the teacher guidebooks, which were not present in the curriculum. The findings in this study could provide some suggestions to the current project of developing 2015 Science Curriculum in regard to understanding the dimensions of knowledge and cognitive process of learning objectives and their alignments with textbooks and teacher guidebooks.

  • 본 연구는 4차 산업혁명 시대를 예고하는 사회 변화 속에서 Bloom의 신교육목표분류학에 기초하여 2015 개정 가정과 성취기준을 분석하고 핵심역량과 지식의 연관성을 찾는데 목적을 두었으며 본 연구의 결과는 다음과 같다. 첫째, 지식 차원은 중학교 성취기준에서는 메타인지적 지식이, 고등학교 성취기준에서는 사실적 지식이 가장 높게 나타났으며 지식 차원의 하위유형은 구체적 사실과 요소에 대한 지식이 가장 높게 나타났다. 인지과정 차원은 중학교 성취기준에서 '적용하다', '분석하다', '평가하다', '이해하다', '창안하다'의 순으로, 고등학교 성취기준에서는 '이해하다', '평가하다', '창안하다', '적용하다', '분석하다' 순으로 나타났다. 둘째, 핵심 개념별로 지식 차원과 인지과정 차원은 '발달'에서 메타인지 지식과 '이해하다', '관계'에서 개념적 지식, 메타인지적 지식과 '이해하다', '생활문화'에서 메타인지적 지식과 '적용하다', '안전'에서 절차적 지식과 '평가하다', '분석하다', '관리'에서 사실적 지식, 절차적 지식과 '적용하다', '생애설계'에서 메타인지적 지식, 사실적 지식과 '이해하다'가 높게 나타났다. 셋째, 성취기준에 사용된 동사의 진술은 '탐색하다', '이해하다', '분석하다', '실천하다', '제안하다', '인식하다', '평가하다'의 순으로 나타났다. 행동 동사의 진술은 수행과정을 판단할 수 있는 기준이 되므로 교과내용 지식과 다양한 인지과정을 나타내는 성취기준에 반영되어 구체적인 역량을 성취할 수 있다. 따라서 성취기준을 통해 학습자의 수행능력의 습득에 더욱 효과적인 인지과정을 제공하고 내용요소와 기능과의 연결을 정교화하는 전략을 통해 교육의 방향성을 높이고 학습자들이 미래를 대비하는 역량을 함양해나갈 수 있도록 지원해야할 것이다.

  • The model of a FMS (Flexible Manufacturing System) admits to a natural hierarchical decomposition of highly decoupled units with similar structure and control. The FMS fractal architecture model represents a hierarchical structure built from elements of a single basic design. A SES (System Entity Structure) is a structural knowledge representation scheme that contains knowledge of decomposition, taxonomy, and coupling relationships of a system necessary to direct model synthesis. A substructure of a SES is extracted for use as the skeleton for a model. This substructure is called pruned SES and the extraction operation of a pruned SES from a SES is called pruning (or pruning operation). This paper presents a pruning operation called recursive pruning. It is applied to SES for generating a model structure whose sub-structure contains copies if itself as in FMS fractal architecture. Another pruning operation called delay pruning is also presented. Combined with recursive pruning the delay pruningis a useful tool for representing and constructing complex systems.

  • 2015 개정 교육과정에서 제시한 백워드 디자인은 목표와 평가의 일관성을 고려하고, 지식의 본질을 강조하고 있다. 그러나 기존의 수업 설계 방식과 달라서 현장의 교사들이 적용하는데 어려움이 있다. 이에 본 연구는 정보과의 관점에서 교사들에게 익숙한 교육목표분류학과는 어떤 차이가 있는지 비교하기 위한 목적이 있었다. 분석 결과, 백워드 디자인에서 어려워하는 '이해'의 6관점은 수준(hierarchy)이 없다고 했지만, 교육목표분류학에서 제시한 6단계의 수준(a hierarchy of six levels)과 유사한 것으로 논의되었다. 새로운 이론이 제시될 때, 해당 지식을 받아들이고 적용하는 것은 매우 어려운 일이다. 본 연구는 새로운 이론에 대해서 충분한 분석을 토대로 받아들여야 한다는 것, 현장 적용성을 높이기 위해 노력해야 할 부분을 제시했다는 점에 의의가 있다.

  • The need for cyber resilience is increasingly important in our technology-dependent society where computing devices and data have been, and will continue to be, the target of cyber-attackers, particularly advanced persistent threat (APT) and nation-state/sponsored actors. APT and nation-state/sponsored actors tend to be more sophisticated, having access to significantly more resources and time to facilitate their attacks, which in most cases are not financially driven (unlike typical cyber-criminals). For example, such threat actors often utilize a broad range of attack vectors, cyber and/or physical, and constantly evolve their attack tactics. Thus, having up-to-date and detailed information of APT's tactics, techniques, and procedures (TTPs) facilitates the design of effective defense strategies as the focus of this paper. Specifically, we posit the importance of taxonomies in categorizing cyber-attacks. Note, however, that existing information about APT attack campaigns is fragmented across practitioner, government (including intelligence/classified), and academic publications, and existing taxonomies generally have a narrow scope (e.g., to a limited number of APT campaigns). Therefore, in this paper, we leverage the Cyber Kill Chain (CKC) model to "decompose" any complex attack and identify the relevant characteristics of such attacks. We then comprehensively analyze more than 40 APT campaigns disclosed before 2018 to build our taxonomy. Such taxonomy can facilitate incident response and cyber threat hunting by aiding in understanding of the potential attacks to organizations as well as which attacks may surface. In addition, the taxonomy can allow national security and intelligence agencies and businesses to share their analysis of ongoing, sensitive APT campaigns without the need to disclose detailed information about the campaigns. It can also notify future security policies and mitigation strategy formulation.

  • This study aimed to analyse the test contents of the national examination for the registered nurses (NERN) over 3 years from 1991 to 1993 in Korea. In recent years in Korea, the MCQ(multiple choice question) has been showing to be a highly recognized method for assessing the qualification of registered nurses. Unfortunately, nursing faculties have found NERN had some bad MCQs through having evaluation workshop for Some MCQs often provide so many unwriting clues which become a bias of the results, and some items fell into the category of the lower level of educational taxonomy such as isolated recall a fact or data. Frequently the stems of the questions are ambigous, unclear, disputable, esoterical or trivial. Considering those fallacies of the national examination, it is very critical to review the test items to see whether it is of high quality, is more fair, reliable and objective in depth. Therefore, this study was done to provide data for the improvement of the test contents as well as the teachers's assessment skill. For this study, the ad hoc committee was composed of 16 members, including 5 education board members of Korean Academic Nurses Association and 11 nursing faculty members. This committee had one day panel discussion and filled the checklist for this study. The process of analysing data was held over 10 times during 1992-1994. The analysis focussed on educational taxonomy such as cognitive domain(knowledge), psychmotor domain (skill), affective domain(attitude) and the level of learning such as recall, understanding, problems solving, and learning area of theory and practice, and the learning content categorised by nursing process and disease process. The test analysed using difficulty index and the structure of the test items was analysed. The conclusions and suggestion as follows : 1. In learning area, the average ratio of the theory and practice was 1 : 1.1 which was less than 1 : 2 suggested by Korean National Health Institute, and the ratio was different by the 8 leaning subjects of nursing. 2. In category of the educational taxonomy, the knowledge domain was emphasized mostly(79. 7%), the skill domain was 14.9%, and the attitude domain was 5.4% only. 3. In the level of learning, generally, the test items of the level of recall(45.5%) and the understanding(46.3%) were covered almost and the problem solving was 8.1%. 4. In the learning contents, generally, the test items related to nursing process was 67.2% and that of disease process was 32.8%. However, this proportion was different by the 8 leaning subjects. Even though the nursing diagnosis has been emphasized in nursing curricula recently, the test items of this was identified very few. 5. In the structure of the test item, some were not clear, incorrect grammar, unclear description and some have clues to answer. 6. In the item analysis, the non-acceptable level of the difficulty index (means too easy) was 65.7%, and the acceptable level was 33.9%. Considering the results we would like to suggest the followings, 1. Since the test items of knowledge domain was dominant, the test items of the practice domain and attitude domain should be emphasized more. 2. The regular review and analysis of NERN should be arranged in order to improve the quality of the test items which will give influence to the nursing education positively.

  • Enhanced machine reliability has dramatically reduced the rate and number of railway accidents but for further reduction human error should be considered together that accounts for about 20% of the accidents. Therefore, the objective of this study was to suggest a new taxonomy of performance shaping factors (PSFs) that could be utilized to identify the causes of a human error associated with railway accidents. Four categories of human factor, task factor, environment factor, and organization factor and 14 sub-categories of physical state, psychological state, knowledge/experience/ability, information/communication, regulation/procedure, specific character of task, infrastructure, device/MMI, working environment, external environment, education, direction/management, system/atmosphere, and welfare/opportunity along with 131 specific factors was suggested by carefully reviewing 8 representative published taxonomy of Casualty Analysis Methodology for Maritime Operations (CASMET), Cognitive Reliability and Error Analysis Method (CREAM), Human Factors Analysis and Classification System (HFACS), Integrated Safety Investigation Methodology (ISIM), Korea-Human Performance Enhancement System (K-HPES), Rail safety and Standards Board (RSSB), $TapRoot^{(R)}$, and Technique for Retrospective and Predictive Analysis of Cognitive Errors (TRACEr). Then these were applied to the case of the railway accident occurred between Komo and Kyungsan stations in 2003 for verification. Both cause decision chart and why-because tree were developed and modified to aid the analyst to find causal factors from the suggested taxonomy. The taxonomy was well suited so that eight causes were found to explain the driver's error in the accident. The taxonomy of PSFs suggested in this study could cover from latent factors to direct causes of human errors related with railway accidents with systematic categorization.

  • What is learning in the math classroom? Does a new term need to be coined for learning? Is the term over-used and it has lost it meaning? The responses of one hundred five teacher-candidates and graduate students were coded using the five levels researcher designed rubric which was modeled after Bloom's Taxonomy for depth of knowledge. The effects of understanding learning include the preparation of lesson plans, classroom instruction, the guiding of student learning, and the professional development of teacher leaders.
