본 연구는 'Bloom의 신교육목표 분류체계'에 준거하여 2007 개정 10학년 교과서 6권과 성취기준을 지식차원과 인지과정 차원의 이차원적 분석을 하였다. 분석을 위해 'Bloom의 신교육목표 분류체계'에 따른 분석에 참여한 경험이 있는 전문가 2명으로 코더(coder)를 선정하여 개별적으로 1차 분석을 한 후 2차에 걸친 협의회를 통해서 최종 판정에 합의하였다. 본 연구의 결과, 교과서에 진술되어 있는 학습목표는 지식차원의 주요유형은 "미래의 가족생활" 단원에서는 사실적 지식과 절차적 지식 범주에, "가정생활문화" 단원에서는 사실적 지식과 개념적 지식 범주에 편중되어 있었으며, 성취기준에 진술되어 있는 "미래의 가족생활" 단원과 "가정생활문화" 단원 모두 사실적 지식에 해당하는 학습목표로만 구성되어 있었다. 교과서와 성취기준에서 지식차원의 하위유형은 구체적 사실과 요소에 관한 지식(AB)이 가장 많았다. 인지과정차원의 주유목은 교과서에서는 '이해하다'와 '분석하다'의 범주에 집중되어 있었고, 성취기준에서는 "미래의 가족생활" 단원에서는 '분석하다' 범주로만, "가정생활문화" 단원에서는 '이해하다' 범주로만 진술되어 있었다. 연구결과로부터 교과서와 성취기준은 메타인지에 대한 지식과 고차적 인지과정의 활동이 미흡함을 알 수 있었다. 따라서 교사는 수업을 설계할 때 성취기준과 교과서에 진술된 학습목표에만 의존할 것이 아니라 고등사고 능력 신장을 위한 학습목표 재진술이 필요하고, 성취기준은 중단원보다 더 세부적인 소단원 및 내용요소별로 구체적이고 세분화하여 제시하여야 하며, 이후 2009 개정 교육과정에 따라 개발되는 교과서에서는 다양한 지식차원과 인지과정 차원을 고려한 학습목표의 진술이 요구된다.

이 연구는 지식유형에 따른 표상 차이를 확인하기 위해서 범주지식과 각본지식의 위계성과 전형성에 대한 점화효과를 측정하였다. 실험 1에서는 상위개념을 점화단어로 제시하고 하위개념을 목표단어로 제시한 다움 목표단어의 어휘판단시간을 측정하였다. 그 결과, 범주지식은 전형단어가 비전형단어보다 반응시간이 빨랐지만, 각본지식은 두 조건간의 차이가 없었다. 실험 2에서는 하위개념을 점화단어로 제시하고 상위개념을 목표단어로 제시한 다음 목표단어의 어위판단시간을 측정하였다. 범주지식이 각본지식보다 반응시간이 빨랐으며, 두 지식 모두 전형성 효과는 관찰되지 않았다. 이러한 결과는 범주지식은 전형성에 따른 위계구조를 구성하지만 각본지식은 범주지식에 비해서 위계성과 전형성이 약회된 구조로 표상될 가능성을 시사하는 것이다.

분산 협동 정보시스템은 분산. 이질적인 정보환경에서 다양한 지식원과 문제 해결 능력 등을 가지면서 이들이 서로 통합되어 사용되는 시스템을 말한다. 이러한 시스템에서는 구성 정보를 서로 활용하고 제어할 수 있는 조정기능이 필요하고 이러한 조정기능의 역할에 따라 전체 시스템의 양태가 다양하게 결정된다. 본 논문에서는 다중에이전트 패러다임을 적용하여 분산 협동 정보시스템의 한 가지 모델을 제시하고 테스트 시스템을 구현해보았다. 제안 시스템은 분산된 구성원을 에이전트화하고 이들 간의 협동을 원활하게 할 수 있도록 조정 에이전트를 사용하고 조정 에이전트를 사용하고 있다. 본 시스템에서 제안된 조정 에이전트는 지식의 세밀도(granularity) 레벨을 이용하여 에이전트 활성화 순서를 조정한다. 즉, 처음에는 단수하면서도 빠른 속도의 지식 형태를 활용하고 그 결과에 따라 좀 더 복잡한 지식 베이스를 활용하도록 하는 것이다. 제안구조는 동일한 주제에 대하여 여러 레벨의 지식원이 존재할 때 이들을 적절히 순서화함으로써 마치 인지과정에서 의식의 초점(focusing)이 자연스럽게 바뀌는 것과 같은 효과를 얻을 수 있을 것이다.

Dramatic development of information technology requires new type of sales strategy to enterprise S/W dealers. That is, one should thoroughly consider diversified types of enterprise S/W and more elaborated consumer needs to establish successful sales strategy. However, various factors that should be considered in establishing enterprise S/W sales strategy are different according to types of enterprise S/W and hard to be managed systematically which led to the current situation where they have not been discussed enough. Therefore, this study introduced the relationship between the factors that affect selection of enterprise S/W using the concept of cognitive map on various enterprise S/W sales cases. Through this process, this study grouped the cognitive maps of similar cases to introduce their characteristics and made this result to be practically useful to enterprise S/W sales strategy.

Spectrum sensing is an important functionality for cognitive users to look for spectrum holes before taking transmission in dynamic spectrum access model. Unlike previous works that assume perfect knowledge of the SNR of the signal received from the primary user, in this paper we consider a realistic case where the SNR of the primary user's signal is unknown to both fusion center and cognitive radio terminals. A Kalman filter based adaptive Takagi and Sugeno's fuzzy system is designed to make the global spectrum sensing decision based on the observed energies from cognitive users. With the capacity of adapting system parameters, the fusion center can make a global sensing decision reliably without any requirement of channel state information, prior knowledge and prior probabilities of the primary user's signal. Numerical results prove that the sensing performance of the proposed scheme outperforms the performance of the equal gain combination based scheme, and matches the performance of the optimal soft combination scheme.

The dependence on cars for urban mobility and the exponential increase in traffic and urban infrastructure to sustain traffic have lead to an encapsulated way of life, where the connection with the natural environment is much more reduced and programmed. In a previous study, a process based on estimating distances showed that children who move around their city by automobile do not appreciate their environment as a spatial continuum, but rather as a series of independent spaces that are reached by automobile or bus, thereby evidencing a different way of conceptualizing urban space in the light of different cognitive structures (Goluboff, Garc$\acute{i}$a-Mira, and Garc$\acute{i}$a-Font$\acute{a}$n, 2002). The present study is concerned with the process of understanding and knowledge of urban space, and contrasting the cognitive structure of different groups. The implications that this study may have for urban planning are discussed.

This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

This study examined the effects of the learning cycle model by learner's characteristics such as I.Q., cognitive levels, inquiry skins, cognitive style, activity, reflectiveness. To see the effects of the learning cycle model, nonequivalent control group pretest-posttest multiple treatment designs was used in the study. 99 middle school second-graders(female) were divided into two groups. One group was selected as the experimental group (n=50), the other served at the comparison group(n=49). During the eight-month period, the students in the experimental group were instructed according to the learning cycle model, while the students in the comparison group were instructed according to the traditional instruction methods. Achievement data from science achievement test were analyzed by an ANOVA technique. The results of the study are as follows : 1. Science knowledge achievement. For the lower level students of activity, the learning cycle model is superior to the traditional approaches in science knowledge achievement. 2. Science inquiry skills. For the upper level students of I.Q., cognitive levels, inquiry skills, cognitive style and reflectiveness, the learning cycle model is superior to the traditional approaches in science inquiry skills. 3. Attitudes toward science. For the lower level students of I.Q., cognitive levels, inquiry skills, cognitive style, activity and reflectiveness, the learning cycle model is superior to the traditional approaches in attitudes toward science.

For an appropriate assessment in mathematics, students should play an active role in their learning by becoming aware of what they have learned in mathematics and by being able to assess their attainment of mathematical knowledge. The process of actively examining and monitoring students' own progress in learning and understanding of their mathematical knowledge, process, and attitude is called self-assessment, Researchers in mathematics education have found some important facts about the meta-cognitive process which is related to self-assessment : i. e. meta-cognition progress is composed of being aware of ones' own personal thinking of content knowledge and cognitive process(self-awareness) and engagement in self-evaluation. Tipical method for self-assessment in mathematics developed upon above finding about meta-cognitive progress is describing about students' knowledge and their problem solving strategies. In the beginning of the description in mathematics about themselves, students are required to answer which part they know and which part they don't know. Self-assessment of students' attitudes and dispositions can be just as important as assessment of their specific mathematical abilities. To make the self-assessment method a success, teachers should let students' have confidence and earn their cooperation by let them overcoming fear to be known the their ability to other students. In conclusion, self-assessment encourages students to assume an active role in development of mathematical power. For teachers, student self-assessment activities can provide a prism through which the development of students' mathematical power can be viewed.
