  • 신경과 의사들은 실제 임상에서 환자들에게 대뇌피질감각의 이상 여부를 알기 위해 손바닥에 숫자나 문자를 쓰게 하여 알아 맞추게 하는 검사를 시행한다. 손바닥에 쓰여진 문자나 숫자를 인식하기 위해서는 몇 가지 단계의 인지과정이 필요할 것으로 생각된다. 첫번째로 손바닥에 닿는 감각을 인지해야 하고, 다음 단계로 이 감각들을 시공간적으로 통합하는 과정이 필요할 것이고, 이러한 정보들을 유지하면서 마지막 단계로 우리 머리 속에 있는 문자와 일치시키는 과정이 필요할 것이다. 본 연구에서는 위와 같은 가설 아래 각각에 해당할 수 있는 뇌영역을 밝히기 위해 기능적 뇌자기공명영상을 이용하였다. 손바닥의 일차적 감각을 인지하는 데는 일차감각영역이 활성화 되었고, 이차감각영역의 활성은 감각들의 시공간적 통합과 관련될 것으로 생각되었으며, 이것들을 유지하는 것은 작업기억의 하부구조인 시공간 그림판과 관련되는 영역이며, 문자를 일치시키는 과정은 브로카영역 부근의 활성과 관련되는 것으로 생각되었다. 위의 가설에 대한 추가검증 및 실제로 일어나는 인지과정에 대한 추가적인 연구가 필요할 것이다.

  • This research is for acquiring implications to science education based on learner's characteristics by analyzing the relationship between contents on science learning and cognitive domain of students in elementary schools through TIMSS 2011-based academic achievement test. Forty one multiple choice items from by TIMSS 2011 were used on 317 primary school students, fourth to sixth grade, and according to grade and achievement level of research targets, test results were analyzed. With these data, the relationship between contents on science learning and the score by cognitive domains, and through correlation by items, we drew static and negative correlations, and then compared the value. The result are as follows: First, other fields except for 'physical science' and 'inference' revealed meaningful differences by learners' grade, and the interrelationship between all contents domains and cognitive fields also appeared statically different. Second, both achievement level of contents and cognition of learners presented significant differences, but the correlation between scientific contents and cognitive field of learners showed different aspects. Third, in static and negative correlation by items, the complexity and their aspects could be classified by targets' academic achievement levels.

  • The consistency and balance of objectives by objective domains in units, sub-units and instructional units were investigated. The 6th elementary biology curricular teaching guidebooks were analysed. Domains of objectives are cognitive, inquiry process, instrumental skill, creative, affective and STS. Cognitive objectives were most dominant in all units, sub-units and instructional units. But no objective for creative domain were suggested. In unit and sub-unit, proportions of objectives were cognitive, inquiry process, affective, instrumental skill and STS domains in order. Objectives for cognitive and inquiry process domains were more than others in instructional units, Except cognitive and inquiry process domains, objectives for the others were not consistent in all units, sub-units and instructional units. Especially, the percentages of objectives for affective domain decreased in units, sub-units and instructional units orderly. These resulted from teaching objective domains categorized formally, Thus, it is necessary to develope curriculum and textbook to be consistent and balanced with objective domains and reflect upon the characteristics of them.

  • The purpose of this paper is to show the limitations of Just War Theory in evaluating ethical issues that can be raised in cognitive warfare, which is emerging as a new area of war. To this end, we will provide the background of cognitive warfare, derive the features of cognitive warfare based on conceptual analysis of cognitive warfare, and clarify the differences between cognitive warfare and traditional warfare. Afterwards, we will turn the discussion and take a look at the background and areas of Just War Theory as a theory that evaluates comprehensive ethical issues related to war. Then, we will elaborate what Just War Theory is and apply the ethical judgment criteria presented in the three areas of this theory, jus ad bellum, jus in bello, and jus post bellum, to cognitive warfare. Finally, we will evaluate the appropriateness of ethical judgment in cognitive warfare by applying criteria for each area and specify the limitations, thereby showing that Just War Theory has limitations as an ethical judgment criteria in cognitive warfare.

  • In order to understand the character of university students, this study confirmed the gender tendency of whether there is a difference in the character of university students according to gender, and if there is a difference, what characteristics there are. It was confirmed through which pathways the cognitive, emotional, and behavioral factors, which are the character factors of university students, affect them. The research results are as follows. First, according to gender, the character of university students was found to be different in all areas of cognition, emotion, and behavior. It was confirmed that female students were higher than male students in all areas. Second, as for the pathways of university student character factors, it was confirmed that the higher the level of the cognitive domain, the higher the level of the affective domain, and the behavioral domain was improved. The results derived from this study can be objective basic data for developing a character education course or program for university students.

  • The goal of this study is to investigate the features of Korean eighth graders' achievement and its trend in Chemistry in TIMSS 2011 and TIMSS 2015, and to explore its implications for Korean science curriculum and in teaching science. With three science educators and six science teachers, we analyzed the characteristics of Korean eighth graders' achievement in Chemistry by test-curriculum matching analysis. According to the trend analysis of science topics with released items for Chemistry in TIMSS 2015, Korean students' percentage for correct answers has dropped in topics such as regularities in chemical reactions, oxidation-reduction, etc. since these topics are covered after the ninth grade in the 2009 revised curriculum. For science cognitive domains, Korean students showed weaknesses in 'applying' domain in TIMSS 2015. Based on the results, we suggested implications for improvement in middle school chemistry curriculum and how to improve science teaching and learning for students' better science competencies and real-world application of science knowledge.

  • The framework for mathematics assessments traditionally has been organized around two dimensions, a content dimension specifying the subject matter to be assessed within mathematics, and a cognitive dimension specifying the domains or thinking processes to be assessed. The cognitive dimensions describe the sets of behaviors expected of students as they engage with the mathematics content. The purpose of this paper is an attempt to make diversify and concrete the sets of behaviors by reviewing the current strands suggested by CAST(College Scholastic Ability Test), assessment framework developed by KEDI, and NAEA(National Assessment of Educational Achievement), and as famous foreign tests PISA, TIMSS, NAEP and NCTM.

  • We have analyzed the science-gifted educational program (year 2002) at the Seoul National University in terms of its educational objectives, scientific models, and cognitive processes in scientific inquiry in order to provide insights into developing and improving science-gifted educational program. We assumed the following items as important factors for teaching scientifically gifted students: higher-order thinking skills involving synthesis domain in the educational objectives, highly abstract nature and complexity in the scientific models, cognitive processes of planning experiments in the cognitive processes in scientific inquiry. According to the analyzed results, the program has the following characteristics: (1) the rates of both higher and lower-order thinking skill domain in the educational objectives are similarly high, but the rate of synthesis domain is relatively low; (2) in the case of the scientific models, the rate of the multiple concepts and/or processes model is relatively low, while the level of the abstractness is relatively on average (3) cognitive processes of authentic scientific inquiry is not thoroughly reflected in the scientific inquiry activities, and very few cognitive processes of planning experiments factor is reflected. Therefore, we conclude in the synthesis domain in the educational objectives, multiple concepts and/or processes model, and cognitive processes of planning experiments should be especially reflected more on the science-gifted educational program in order to serve the needs of scientifically gifted students.
