The effect of spatial attention gradually decreases as a function of the distance between the locus of attention and a target. According to this hypothesis, we tested the spatial-effect profile of visual attention when it operates on perception and memory. Experiment 1 measured accuracy of discriminating the color of a simultaneously masked target after presenting a pre-cue to either at the target location or away from the target (perception-intensive task). Experiment 2 measured accuracy of recognizing the color of several items at and around the pre-cued location (memory-intensive task). In the perception-intensive condition, the accuracy gradually dropped as the distance between the cue and target location increases. However, in the memory-intensive condition, subjects remembered only the item at the cued location. This suggests spatial attention in a memory-intensive process would operate on object-based representations. Experiment 2 showed the object-based effect observed in Experiment 1 can be also present in perception under a special circumstance. The results indicate that spatial attention can operate on object-based representations in a memory-intensive process whereas it flexibly can operate either on location-based or object-based representations in a perception-intensive process.

The purpose of this study is to identify the effect of problem solving with task-based activities on understanding of major concepts and learning attitude in 'Applications of ICT' subject. In teaching the 4th class of 'Applications of ICT' subject, problem solving with reasoning task-based activities are used for the experimental groups and instructor-oriented teaching for the comparative groups. The results are as follows: First, no meaningful difference was found in the pretest result of concepts of ICT, while posttest found that the students with problem solving with reasoning task-based activities in experimental group marked average 5.87 point higher than the control group and showed meaningful difference at significance level p<.05. Dividing concepts about Information Communication Technology into four domains, there were no meaningful difference between two groups in the concept test about communication principles and methods and network, while the test results about the other two concepts, that is, expressions and patterns of information and compositions and types of communication network, showed the meaningful difference at significance level p<.05. Second, the research proved that the experimental group with problem solving with reasoning task-based activity teaching, compared to the control group with lecture, showed desirable change in learning attitude. From the results, the solving with reasoning task-based activity model is better teaching-learning method compared to lecture, revealing positive change in understanding major concepts of information and communication technology and learning attitude.

This study aims to investigate what to be prepared and implemented for the military integration when South and North Korea are making progress toward unification. Although we can not exactly predict when the unification will be completed at this time, preparations for the military integration should be ready ahead of time. Since the failure of the military integration can threat the unification, elaborated and practical solutions are required. Therefore, the study tries to answer the following questions : 1) What types of the military integration are desirable and what are the prerequisites for the unification of Korean Peninsular? ; 2) What potential military tasks could be caused by military integration? ; 3) What are the core and major tasks among them and how could they be solved in practical aspects?

"여성은 수학을 못한다" 또는 "수학적 능력에 있어서 남학생이 여학생보다 우월하다"는 우리 사회의 일반적 통념은 근거가 있는 것인가? 1970년대 이후 구미를 중심으로 외국에서는 교육에서의 성 평등(equity) 문제에 대한 관심이 높아지면서 수학에서의 성별차이(gender difference)에 대한 연구들이 상당히 이루어져 왔다. 그러나 국내의 연구는 한국학술진흥재단의 연구지원을 반아서 수행된 96년부터 98년까지의 3년 연구(권오남, 박경미, 임형, 허라금의 공동연구) 이외에는 거의 전무하다. 이 글에서는 수학적 능력에서의 성별차이라는 논제를 3년 연구의 결과를 중심으로 양적, 질적 연구방법으로 접근하며, 이를 바탕으로 수학교육에서의 양성평등의 과제와 전망을 논의한다.

Recently, the importance of team based learning has emerged as the method for conducting the constructivist learning theory. College students, however, have the low preference toward team projects. Thus, this research suggested that the information literacy education should be designed to overcome the problems in team project activities after analyzing the college students' information problem solving process. The in-depth interviews were conducted twice with 10 subjects. As a result, the main problems during team project activities were task definition, judgement on relevant information, evaluation of result and process, absence of accountability and synthesis. The recommendations for information literacy course are as follows: introduction to different types of information sources, support for communication problems between team members, education of credibility judgment on information and criteria for evaluating the results.

The purpose of this study is to analyze tasks for mathematical competencies in the 8th grade mathematics textbooks based on the 2015 revised mathematics curriculum. And our study is based on the distribution of competencies of tasks for mathematical competencies in the 8th grade mathematics textbooks The results of this study were as follows. First, there are distributed in order, in general, geometry unit, letter expression unit, function unit among 8th grade mathematics textbooks for mathematical competencies. Second, there are unbalanced distribution of mathematical competencies among in 8th grade 'mathematics' textbooks. Lastly, there are comprised of textbooks focused on specific elements among subelements of tasks for mathematical competencies in the textbooks.

혁명과 퇴폐라는 양극적 문화형태는 어디까지나 중심이 아닌 주변문화의 형태인 것이다. 그렇다면 중심은 없고 주변문화만 왕성했던 지금까지의 청년문화는 어떤 방향에서 중심문화를 잡아나가야 할 것인가가 이제 과제가 된다. 중심 없는 주변문화의 극성은 청년문화의 실종인 동시에 우리 모든 문화의 구조적 취약점이다.
