가상현실을 이용한 교육시스템에서 학습자를 대신한 에이전트의 설계에 대한 많은 연구가 이루어지고 있다. 이러한 에이전트의 설계에 있어서 가장 중요한 점은 동적으로 변화되는 환경에서 이루어지는 다양한 현상과 사건들을 인식하는 방법과 이에 대해 반응하는 행동의 설계와 구현에 있다. 본 논문에서는 에이전트의 행동을 설계함에 있어서 교육 시스템의 목적에 부합하기 위한 주위 객체들과의 상호작용을 통한 행위의 인식, 장이론을 이용한 공간객체와의 상호작용 등을 이용하여 좀 더 효율적으로 주위 환경에 반응할 수 있는 자율 에이전트의 행위에 대한 방안을 제시한다.

윤리란 행위의 옳고 그름이나 선과 악 또는 도덕적인 것과 비도덕적인 것에 관한 판단기준의 체계 혹은 이를 대상으로 하는 학문을 말한다. 또한 윤리는 그 적용대상이 무엇인가에 따라 가정윤리, 사회윤리, 직업윤리, 기업윤리, 정보윤리 등 여러가지로 나누어 볼 수 있다. 여기서 정보통신윤리란 윤리의 문제를 정보통신 또는 정보화사회의 관점에서 조명한 것이라 볼 수 있으며 정보를 다루는데 있어 개인이나 사회구성원들의 행동이나 규범체계로서 그들의 행동이나 태도의 옳고 그름, 좋고 나쁨, 그리고 윤리적인 것과 비윤리적인 것을 판단하게 해주는 기준체계라 할 수 있다.

인공 신경망은 체계적인 알고리즘으로 풀기 어려운 문제들을 해결하는데 사용되어오고 있다. 이는 인간의 뇌세포가 외부자극에 대해 반응하는 과정을 컴퓨터 시스템 상에서 구현한 것으로 새 인간과 컴퓨터의 상호작용을 연구하는데 흥미로운 접근방식이다. 본 논문에서는 신경망의 접근방법을 이용하여 인간행위 인식시스템을 구현하였다. 신경망을 이용해 구현된 컴퓨터 인식 시스템이 인간의 두 가지 정서 하에서 일어난 세가지 서로 다른 행동을 보고 행위자의 성별이나 강정상태를 얼마나 인식해낼 수 있는지 실험해 보았다. 특히, 성별 인식 실험에서는 신호탐지 이론에서 사용하는 인장도(discriminability)를 이용해 사람에 대한 이 시스템의 효율도를 계산하였다

최근에 이르러 자동차의 대수는 급격히 증가해 왔다. 이런 경향성의 결과로 나타난 교통사고의 인적 및 물질적인 손실이 최악의 상태에 이르른 것이 사실상 오늘날 우리들의 불행한 현실이다. 대다수의 교통사고가 운전자의 교통법규 위반에 기인되고 있다는 전제하 에 본 논문은 심리학적인 관점에서 그와같은 위반적인 운전자 행동의 이론적 배경을 비판적으로 분석하고자 시도한다. 아울러 이 논문에서는 운전자의 법규 위반적 행동에 대해 취할 수 있는 기본적이 대책을 마련 하는데 있어 특별히 기여할 수 있을 "인간-환경-경험" 모델을 구축하는 기초를 마련하고자 노력하고 있다.자 노력하고 있다.

The design and implementation of agents is an essential part of the development of immersive types of tutoring systems using virtual reality. This paper proposes several effective mechanisms for the design and implementation of agents. Unlike existing researches we focus on accommodating diversity of agents' behavior in the proposed mechanisms. First, we define the space object based on the field theory. The introduction of the field theory allows us to approach the space objects in a structural manner rather than by their classification. We can also achieve dynamic genesis and extinction of the space objects, and derivation of overall changes in spatio-temporal situations. Second, we classify the behavior of agents into composite behaviors and primitive actions in order to achieve its dynamic planning. Finally, we distribute the knowledge among agents and their associated objects according to their interrelations. By this distribution, we can handle the otherwise prohibitively large amount of knowledge related to agents' behaviors and construct a dynamic environment. By implementing a situation with agent's navigation across a composite space object, we demonstrate the effectiveness of these schemes presented above.

The biggest strength of the Internet is to enable to access information without any limitation of time and space. As the Internet and IT technologies have been developed, various kinds of teaching ways in education field such as remote lectures, video lectures, and CAI(Computer Adapted Instruction) have emerged. In terms of education, evaluation can be a basic foundation to help teach students in the next learning stage according to each student's level. In addition, it is able to give the information of students'abilities and provides proper learning programs to teach students on a case-by-case basis. The purpose of the paper is to establish evaluation system on the WWW(World Wide Web) that can reflect learning activities part of students in their evaluation scores based on the two important learning theories, Behaviorism and constructivism, which are mainly used in evaluation procedures to judge learning ability of students. This system will give information about learners, and analyze the learning interest of learners. The proposed system enables teachers to evaluate learning ability of students through various kinds of information of learners, and to execute level-based education.

In this study, the achievement of Korean biology gifted-students was compared with that of International Biology Olympiad(IBO) participants to explore international achievement level of biology and to suggest the need of teaching program for biology gifted-students. Korean thirty gifted-students were selected through test by Korean Biology Olympiad Committee. They examined theoretical test two times in January and March. 1998. Theoretical part consisted of eight domains as follows; cell biology. anatomy and physiology of plants, anatomy and physiology of animals, ethology. genetics and evolution, ecology, systematics, and microbiology. As a result, Korean biology gifted-students had lower achievement than IBO participants in eight domains. and especially much lower achievement in ethology and systematics. Though thirty Korean gifted-students were found to had much lower achievement than lBO participants, four higher rankers of them are in prospect of winning bronze medals. Thus, it is necessary to develope an appropriate teaching program for biology gifted-students with theoretical lectures and inquiry activities.

With the advent of the era of mass tourism in China and people's yearning for a better life, the demand for family tourism is increasing. This paper adds the filial piety concept variable to the original model based on the theory of planned behavior (TPB). It tests the influence mechanism of attitude, subjective norm, perceived behavior control and filial piety on the intention of family tourism behavior. The results show that； Attitude and subjective norms have significant influence on the intention of family tourism behavior; Perceptual behavior control has no significant influence on the intention of family tourism behavior; Mutual filial piety has a significant impact on family tourism behavior and authoritative filial piety has no significant effect on family tourism decision-making behavior. This conclusion expands the application boundary of the theory of planned behavior in the study of family tourism behavior intentions, and provides application reference for tourists and tourism enterprises.

The purpose of this study is to explain the teacher librarians' intentions to implement collaborative instruction in school libraries by applying theory of planned behavior. Independent variables that affect the intention to implement were set as attitudes, subjective norms, teacher efficacy, and perceived controllability. A questionnaire survey of 218 teacher librarians was conducted. As a result of the study, there was a difference in teacher librarian's intention to implement collaborative instruction in school library according to the age, the size of school and previous experience. Attitudes, subjective norms, and perceived controllability affected the intention to implement collaborative instruction. Teacher efficacy did not affect teacher librarian's intention to implement collaborative instruction in school library. The results of the study were interpreted as a mixed method by using open-ended questions. Based on the results, implication was proposed to expand collaborative instruction in school library.

A growing body of research has focused on the negative effects of Internet gaming. This issue has become an increased public health concern in Korea. However, little is known regarding the positive effect of Internet gaming and its etiology. This study examined the effects of gaming motivations on gaming behaviors based on self-determination theory. Specifically, we investigated the associations of intrinsic and extrinsic gaming motivations with adaptive and maladaptive game uses. A cross-sectional data collected from a sample of 3,000 young adults using 2016 Korean Video Gaming Survey was analyzed. Measurement model analysis and structural equation modeling were conducted as primary analyses. The findings highlight the different effects of intrinsic and extrinsic motivations on gaming behaviors, such as adaptive and maladaptive game uses. Intrinsic motivations, such as experience-seeking and achievement-seeking, were associated with adaptive game use. Meanwhile, extrinsic motivations, such as sensation-seeking and monetary reward-seeking, were associated with maladaptive game use. The findings provide a better understanding of video gaming in light of both adaptive and maladaptive game uses. The implications for practice and policy were discussed.
